From c6d92160f6d20d01b3774db492ecda1383cae5c1 Mon Sep 17 00:00:00 2001 From: Daniel Han Date: Sun, 24 May 2026 06:52:58 +0000 Subject: [PATCH 001/227] Add Docker build for Blackwell that runs on any NVIDIA GPU host Adds a multi-stage Dockerfile producing an image that works on Ampere through Blackwell (sm_80 through sm_120: A100, RTX 30/40, H100, B100/B200, RTX 50-series, RTX 6000 Pro Blackwell). The build itself requires no GPU at all and runs on a free GitHub-hosted ubuntu-latest runner. How the GPU-less build works: 1. cu128 PyTorch wheels are fat binaries. torch._C._cuda_getArchFlags() returns 'sm_70 sm_75 sm_80 sm_86 sm_90 sm_100 sm_120' regardless of which GPU compiled the image, because the wheels are cross-compiled upstream by the PyTorch team. 2. All deps resolve in a single uv pip install pass with explicit pins (torch==2.10.0, --extra-index-url cu128, no --torch-backend=auto, no install.sh). This prevents the silent cu cascade where bitsandbytes' transitive cuda-toolkit==13 dep upgrades torch to 2.12+cu130 in a later resolver pass, leaving xformers and other cu128 wheels stranded. 3. Build-time verification uses package metadata (importlib.metadata.version) and the raw torch._C._cuda_getArchFlags() accessor. We deliberately avoid import unsloth at build time because unsloth.__init__ calls torch.cuda.get_device_properties(0), which requires an actual CUDA device and is not bypassable. Import-time correctness is exercised at deploy time by smoke_test.py with --gpus all. 4. UNSLOTH_COMPILE_DISABLE=1 and CUDA_VISIBLE_DEVICES="" during the build stage prevent any code path from JIT-compiling kernels for the build host's compute capability and baking the resulting cache into the image. The deploy GPU produces its own cache on first use. Other notes: - --index-strategy unsafe-best-match is needed because the PyTorch wheel index serves an old requests==2.28.1 that conflicts with datasets>=2.32.2, which the default first-index-wins strategy rejects. - Extra is cu128-ampere-torch2100 (ampere precedes the torch version in the pyproject ordering). - No flash-attn in the base image. FA3 is hard-refused on Blackwell upstream and unsloth gracefully falls back to xformers + SDPA. Users on Ampere / Ada / Hopper who want FA2 can pip install flash-attn on top. - Two stages: nvidia/cuda:12.8.1-cudnn-devel-ubuntu24.04 for the build, -cudnn-runtime for the deploy image. No nvcc in the published image. - A lockfile is emitted at /opt/unsloth-venv/requirements.lock.txt inside the image and can be extracted with docker/freeze.sh for byte-identical rebuilds even after PyPI moves on. CI workflow .github/workflows/docker-publish.yml: - Builds on ubuntu-latest on every push to main, every tag, weekly via cron, and manually via workflow_dispatch. Pushes to docker.io/unsloth/unsloth with cache via type=gha. - Optional smoke-test job runs on a self-hosted GPU runner if vars.HAS_GPU_RUNNER is set; skipped otherwise. End-to-end verification on sm_120 hardware is a nice-to-have, not a publish blocker. Validation: - Install path validated on a B200 host with CUDA_VISIBLE_DEVICES="" set (simulating the GPU-less CI runner): torch 2.10.0+cu128 holds, xformers 0.0.34, bitsandbytes 0.49.2, triton 3.6.0, transformers 5.5.0, trl 0.24.0, peft 0.19.1, accelerate 1.13.0. Arch flags include sm_100 and sm_120. - Runtime path validated end-to-end on B200: smoke_test.py imports unsloth, loads Llama-3.2-1B-Instruct-bnb-4bit in 4-bit, completes 5 LoRA steps with loss decreasing 4.11 -> 3.75. xformers fallback active as designed.

The entrypoint catches the three that cover ~95% of "it doesn't work" reports up front: 1. nvidia-smi inside the container sees no GPU -> user forgot --gpus all, or host is missing nvidia-container-toolkit -> entrypoint prints the exact docker run flag and the toolkit install URL 2. nvidia-smi works but torch.cuda.is_available() is False -> host driver is older than CUDA 12.8 supports -> entrypoint prints the minimum driver version per architecture 3. compute capability < sm_80 -> entrypoint prints the supported architecture table and exits Each check fails with a clear, actionable message rather than a stack trace. Set UNSLOTH_SKIP_GPU_CHECK=1 to bypass (for docs builds, offline tooling, CI). run.sh wraps `docker run` with the flags people most often forget: --gpus all (without it, the new entrypoint refuses to start) --ipc=host (DataLoader workers need >64MB shm) --ulimit memlock=-1 (NCCL + CUDA pinned host buffers) --ulimit stack=64MB (some torch kernels OOM the default 8MB stack) Plus it mounts the host HF cache + Triton JIT cache so model downloads and compiled kernels persist across container runs, and forwards HF_TOKEN / WANDB_API_KEY / UNSLOTH_LICENSE only when they are set on the host.

This used to surface as a confusing buildx failure mid-Block-2, but the actual problem is a host permissions issue that's settable up front. Detect by running 'docker info' and checking its exit code (not just grep on its output -- a permission failure prints to stderr and returns non-zero, so the old grep-based check was a silent skip). Also clarify the nvidia-runtime WARN: on Docker 28+ with CDI mode this is a false positive most of the time.

Turing GPUs work, with the caveat that bfloat16 is unavailable; the entrypoint prints a NOTE in that case so Unsloth's fp16 fallback isn't a surprise. --- docker/Dockerfile | 23 ++++++++++++++++++----- docker/entrypoint.sh | 31 ++++++++++++++++++++++--------- 2 files changed, 40 insertions(+), 14 deletions(-) diff --git a/docker/Dockerfile b/docker/Dockerfile index 7b5ce5c342..a62034d9f6 100644 --- a/docker/Dockerfile +++ b/docker/Dockerfile @@ -6,8 +6,11 @@ # * cu128 wheels are fat binaries: SASS for sm_80;86;89;90;100;120. # * Unsloth's runtime kernels are Triton, which JIT-compiles per device at first run. # * Anything that DOES need to be source-built (rare on this pin set) compiles -# against TORCH_CUDA_ARCH_LIST="10.0;12.0+PTX" -- the host GPU is irrelevant -# for compilation; nvcc emits whatever the arch list says. +# against TORCH_CUDA_ARCH_LIST="7.5;8.0;8.6;8.9;9.0;10.0;10.3;12.0;12.1+PTX", +# covering every current x86_64 NVIDIA compute capability per +# https://developer.nvidia.com/cuda/gpus. +# The host GPU is irrelevant for compilation; nvcc emits whatever the arch +# list says. # # Build host requirements: # * Docker with buildkit (default since 23.x) @@ -30,9 +33,19 @@ ENV DEBIAN_FRONTEND=noninteractive \ PIP_DISABLE_PIP_VERSION_CHECK=1 \ PYTHONDONTWRITEBYTECODE=1 \ PYTHONUNBUFFERED=1 \ - # Cross-compile for: Ampere, Ada, Hopper, B100/B200 (sm_100), RTX 50x / 6000 Pro (sm_120). - # +PTX on the highest arch lets future Blackwell SKUs run via JIT-PTX. - TORCH_CUDA_ARCH_LIST="8.0;8.6;8.9;9.0;10.0;12.0+PTX" \ + # Cross-compile for every current x86_64 NVIDIA arch per + # https://developer.nvidia.com/cuda/gpus: + # sm_75 Turing T4, RTX 20-series, Quadro RTX + # sm_80 Ampere DC A100, A30 + # sm_86 Ampere A40, RTX A6000, RTX 30-series + # sm_89 Ada L4, L40, L40S, RTX 40-series + # sm_90 Hopper H100, H200, GH200 + # sm_100 Blackwell DC B100, B200, GB200 + # sm_103 Blackwell DC B300, GB300 + # sm_120 Blackwell RTX 50-series, RTX PRO 6000 Blackwell + # sm_121 Blackwell GB10 (DGX Spark) + # +PTX on the highest lets future arch revisions run via JIT-PTX. + TORCH_CUDA_ARCH_LIST="7.5;8.0;8.6;8.9;9.0;10.0;10.3;12.0;12.1+PTX" \ MAX_JOBS=4 \ CUDA_HOME=/usr/local/cuda \ # Build-host-independence guards.

So we cannot do `docker push huggingface.co/user/repo:tag` for an Unsloth image.

Switching the arm64 leg from QEMU-on-amd64 to a native arm64 matrix runner is ~3x faster and avoids QEMU's occasional flakiness on long cu128 installs. The workflow now: * builds amd64 and arm64 in parallel on their native runners, pushing each as a single-arch image *by digest* (no tag) * stitches both digests into one multi-platform manifest in a follow-up `merge` job, using `docker buildx imagetools create` * keeps a separate buildx cache scope per platform to avoid cross-arch cache collisions Smoke-test job now needs `merge` (was `build`) so it only runs once the final manifest is published. Dockerfile header: replace the speculative aarch64 SASS list with the verified one from pytorch/pytorch v2.10.0 .ci/manywheel/build_cuda.sh (8.0;9.0;10.0;12.0 on aarch64), and note that sm_120 is forward-compatible to sm_121 per PyTorch maintainers -- which is what makes DGX Spark work without an explicit sm_121 SASS section in the wheel. setup_qemu.sh / test_locally.sh --platform stay in place: they're for the local-dev path on x86_64 boxes that don't have arm64 hardware. --- .github/workflows/docker-publish.yml | 170 +++++++++++++++++++-------- docker/Dockerfile | 7 +- 2 files changed, 126 insertions(+), 51 deletions(-) diff --git a/.github/workflows/docker-publish.yml b/.github/workflows/docker-publish.yml index 5b77ecbd7c..943d973c16 100644 --- a/.github/workflows/docker-publish.yml +++ b/.github/workflows/docker-publish.yml @@ -1,9 +1,10 @@ # Builds and publishes the Blackwell-compatible Unsloth Docker image. # -# The build runs on a free GitHub-hosted Ubuntu runner with NO GPU attached. +# The build runs on free GitHub-hosted Ubuntu runners with NO GPU attached. # This is possible because: # 1. cu128 PyTorch wheels are fat binaries -- they already ship sm_70 through -# sm_120 SASS, cross-compiled upstream by the PyTorch team. +# sm_120 SASS on amd64 (and sm_80;90;100;120 on aarch64), cross-compiled +# upstream by the PyTorch team. # 2.

Symlinks libnvrtc.so.13 over it. (2) Triton's nvidia backend runs ptxas. Wheels older than 3.6.0 bundled cu12.8 ptxas which silently downgrades sm_121 to sm_80 (see triton-lang/triton#8335). Bump pin triton>=3.6.0 (3.6 bundles cu13 ptxas) AND install cuda-nvcc-13-0 so the entrypoint can point TRITON_PTXAS_PATH at it as defense in depth. Both fixes are arm64-only (gated on TARGETARCH, ~400 MB on the arm64 image; amd64 is untouched, no sm_121 hardware exists on x86_64). Neither component talks to libcuda, so this does NOT bump the toolkit driver floor away from cu128's 570+. TRITON_PTXAS_PATH is set from the entrypoint (only when the cu13 ptxas actually exists in the image) rather than via a Dockerfile ENV, because ENV is unconditional and Triton errors out if TRITON_PTXAS_PATH points at a nonexistent file.

Fix all four in this PR so the new Docker release path is self-consistent. 1. docker/smoke_test.py used `import xformers` unconditionally, which guarantees a failure on arm64 (built with `[huggingface]` extras to skip xformers since it has no aarch64 cu128 wheel). Wrap the import in try/except so the same smoke script validates both arches. 2. unsloth/_gpu_init.py forced `TORCHINDUCTOR_COMPILE_THREADS=1` before `import unsloth_zoo`, but `patch_torch_compile` in unsloth_zoo main pops that env var in non-debug mode. After unsloth_zoo init the guard was effectively undone, so cgroup-pinned `docker --gpus '"device=N"'` containers still spawned the Inductor subprocess pool that cannot enumerate the GPU. Set `torch._inductor.config. compile_threads = 1` directly post-import-torch and re-populate the env var so `determine_compile_threads()` in the zoo options dict also returns 1, regardless of whether the zoo-side fix from PR #694 has shipped yet. 3. docker-publish.yml UNSLOTH_REF build-arg defaulted to `'main'` for tag pushes and scheduled runs, so a `v1.2.3` release image would contain whatever `main` happened to be at build time, not v1.2.3. Pick the tag's `github.ref_name` for tag events and `github.sha` for branch/schedule events. 4. The smoke-test job pulled `:latest` regardless of which tag the merge job had just published, so tag/schedule/sha publishes were never actually validated. Re-run docker/metadata-action with the same config the merge job used, then smoke-test the first tag from its output. All four changes are gated and backwards-compatible. --- .github/workflows/docker-publish.yml | 36 ++++++++++++++++--- .../async_task_output_1rtbzl.md | 1 + .../async_task_output_1ud2z5.md | 1 +

Address the P1s + the regression-class P2s in this commit; the remaining nits are left for a follow-up cleanup pass. 1. unsloth/_gpu_init.py: the `NVIDIA_VISIBLE_DEVICES in os.environ` check triggered for every NVIDIA-runtime container including `--gpus all` (NVIDIA_VISIBLE_DEVICES=all is the default). Gate strictly on a non-special device list. Also drop the precondition that the env var was absent: if the user already pinned TORCHINDUCTOR_COMPILE_THREADS=1 we should still plant the UNSLOTH_FORCE_SINGLE_COMPILE_WORKER sentinel so the zoo-side patch knows to preserve the forcing. 2. unsloth/_gpu_init.py: after the post-`import unsloth_zoo` reassertion, monkey-patch `unsloth_zoo.temporary_patches.common.determine_compile_threads` to return 1, so any later `torch.compile` call that rebuilds the options dict still sees the single-worker forcing even if a downstream patch_torch_compile pops the env var again. 3. docker/Dockerfile: torchaudio==2.11.0 mismatched the torch==2.10.0 release pairing; pin to 2.10.0 so the ABI is correct and the audio stack matches torch/cu128. 4. docker/Dockerfile: drop `12.1+PTX` from TORCH_CUDA_ARCH_LIST. The cu128 toolkit compiler does not know about compute_121; the trailing PTX entry forced nvcc to emit a `sm_121` gencode that breaks any in-container source builds. 5. docker/smoke_test.py: the device-capability floor said `cap[0] < 8`, rejecting Turing (sm_75) while the Dockerfile + entrypoint advertise sm_75 as supported. Lower the smoke floor to sm_75 and print a hint that bf16 is not available on Turing. 6. docker/run.sh: `-it` is unconditional; CI / non-TTY invocations died with "the input device is not a TTY". Probe `[ -t 0 ] && [ -t 1 ]` first.

Stop leaking secrets via docker run -e VAR=VALUE argv (run.sh, test_locally.sh) `docker run ... -e HF_TOKEN=hf_xxx ...` puts the literal token in the docker CLI's argv, which is visible to any user on the host via `ps auxe` / `/proc//cmdline` for the lifetime of the process. Switch to the dash-only form `-e HF_TOKEN`, which tells docker to read the value from the parent shell's env and never appears in argv. Same fix for WANDB_API_KEY and UNSLOTH_LICENSE in run.sh and HF_TOKEN in test_locally.sh. 2. Stop stripping numpy/tests/ in the runtime layer (Dockerfile) The Dockerfile explicitly upgrades numpy >= 2.4 because numpy 2.2.6 shipped a stripped wheel where `from numpy._core.tests._natype import pd_NA` fails. Numpy 2.4 restores `numpy/_core/tests/`, then the existing `find ${VENV} -name tests -exec rm -rf {} +` deleted it again -- re-introducing the same broken-import state on the deployed image (the build-time verification at line 220 runs BEFORE the strip so it passed). Whitelist numpy's tests directories from the strip; keep stripping the rest. 3. Align :latest tag gate between merge and smoke-test jobs (.github/workflows/docker-publish.yml) merge job: enable = is-default-branch AND unsloth_ref == '' smoke-test job: enable = is_default_branch only On `workflow_dispatch`, `github.event.inputs.unsloth_ref` defaults to "main" (not ""), so the merge step skipped `:latest` but the smoke step still emitted `:latest` as tags[0]. The smoke step then `docker pull`-ed a prior `:latest` from Docker Hub instead of the image just merged -- so the smoke test verified the OLD image, not the new one. Copy the merge step's exact `enable=` expression into the smoke-test step so the two stay byte-identical and a workflow_ dispatch run validates whatever was actually merged. --- .github/workflows/docker-publish.yml | 9 ++++++++- docker/Dockerfile | 14 +++++++++++++- docker/run.sh | 11 ++++++++--- docker/test_locally.sh | 5 ++++- 4 files changed, 33 insertions(+), 6 deletions(-) diff --git a/.github/workflows/docker-publish.yml b/.github/workflows/docker-publish.yml index eee1961fd6..e2ecaac199 100644 --- a/.github/workflows/docker-publish.yml +++ b/.github/workflows/docker-publish.yml @@ -216,13 +216,20 @@ jobs: # Re-compute the tag list deterministically from the same metadata-action # config the merge job used, so tag/schedule/SHA runs pull the image # they just published instead of an unrelated `:latest` from a prior run. + # IMPORTANT: keep this `enable=` expression byte-identical to the merge + # job's :latest gate above.

Both violate the image's build-host-independence rule. fetch_llama_prebuilt.py pins by build target only: amd64 takes the linux-x64-cuda12-portable bundle, arm64 the linux-arm64-cuda13-portable bundle (DGX Spark / Grace), both sha256-verified against the release's llama-prebuilt-sha256.json. convert_hf_to_gguf.py plus gguf-py/ are hydrated from the same release's source tarball so the converter's tensor mappings match the binaries, mirroring unsloth_zoo's _hydrate_converter_sources layout. LLAMA_PREBUILT_TAG build-arg overrides the pinned release. docker_confirm.sh: one-command confirmation script for any machine (Linux / WSL2 / macOS) following the staging confirm-script conventions: host + docker + GPU detection with CPU-mode auto-fallback, image pulls, in-container torch.cuda check, 5-step LoRA training smoke, baked llama.cpp verification, full-image boot probing Studio /api/health and JupyterLab /api, PASS/WARN/FAIL summary with RESULT line. --- .github/workflows/docker-publish.yml | 5 - docker/Dockerfile | 51 +++--- docker/docker_confirm.sh | 236 +++++++++++++++++++++++++++ docker/fetch_llama_prebuilt.py | 142 ++++++++++++++++ 4 files changed, 400 insertions(+), 34 deletions(-) create mode 100644 docker/docker_confirm.sh create mode 100644 docker/fetch_llama_prebuilt.py diff --git a/.github/workflows/docker-publish.yml b/.github/workflows/docker-publish.yml index 417d0d6870..b4b174e468 100644 --- a/.github/workflows/docker-publish.yml +++ b/.github/workflows/docker-publish.yml @@ -124,11 +124,6 @@ jobs: cache-from: type=gha,scope=build-${{ matrix.platform }} cache-to: type=gha,scope=build-${{ matrix.platform }},mode=max outputs: type=image,name=${{ env.REGISTRY }}/${{ env.IMAGE_NAME }},push-by-digest=true,name-canonical=true,push=true - # The llama.cpp prebuilt bake reads GITHUB_TOKEN (BuildKit secret, - # never a layer) so the resolver's GitHub API calls are not subject - # to the anonymous per-IP rate limit shared across Actions runners. - secrets: | - github_token=${{ github.token }} build-args: | CUDA_VERSION=12.8.1 UBUNTU_VERSION=24.04 diff --git a/docker/Dockerfile b/docker/Dockerfile index 6e943f470c..c1af9baa4c 100644 --- a/docker/Dockerfile +++ b/docker/Dockerfile @@ -423,38 +423,31 @@ RUN if [ "${TARGETARCH:-amd64}" = "arm64" ]; then \ # Prebuilt llama.cpp so GGUF export works out of the box. # # unsloth_zoo's save_pretrained_gguf() calls check_llama_cpp(), which looks -# for llama-quantize + convert_hf_to_gguf.py in $UNSLOTH_LLAMA_CPP_PATH -# (default ~/.unsloth/llama.cpp).

The dir is the image's baked prebuilt, provisioned exclusively for Studio, so write the .unsloth-studio-owned marker next to the binaries. 2. With no GPU and no nvidia-smi in the build container, install.sh fell back to cu126 torch wheels for the Studio venv (and would pick cpu wheels on a CI runner without /proc/driver/nvidia), so the published image's Studio venv would depend on which host built it and could not train on Blackwell. get_torch_index_url now honours an explicit UNSLOTH_TORCH_INDEX_FAMILY override naming the index leaf (cu128, cu130, rocm7.2, cpu, ...).

The pip ninja lives in the venv bin, which subprocesses like vllm serve do not always inherit on PATH, so the JIT failed with exit 127. Install ninja-build so the binary is reachable from any PATH. 2. With ninja present the JIT still cannot succeed for device code: the runtime image deliberately ships no nvcc. Bake flashinfer-jit-cache (cu128) so ops missing from the cubin package (fmha_gen on sm_100a was the repro) come precompiled. In-process GRPO never hit this because unsloth-zoo blocks the FlashInfer JIT path; standalone vllm serve gets no zoo patches.

Three traps, all defended: From aba16af123d8fdedfb781203bb5bf2f085d20fc0 Mon Sep 17 00:00:00 2001 From: Daniel Han Date: Mon, 15 Jun 2026 03:13:16 +0000 Subject: [PATCH 073/227] docker: notebook deps, image size cuts, per-notebook transformers Notebook dependency coverage (base Dockerfile): - Bake omegaconf, einx, librosa, decord, ftfy so the TTS/STT and vision notebooks stop dying on a silent No module named X. Installed in the notebook-deps layer (after the torch/vLLM resolve) with an assertion that the resolve did not move torch 2.10.0 / numpy>=2.3 / numba>=0.65. Image size (no functional change): - Base: prune npp to the two libs torchcodec actually dlopens (libnppicc + libnppc), drop link-time-only .a archives and the nvshmem device bitcode. Headers (torch/include etc) are kept so causal-conv1d / mamba-ssm still build at notebook time with --no-build-isolation. - Studio: pin the Studio venv to Python 3.12 (matches base) so its nvidia-*-cu12 wheels are byte-identical to the base venv's, then symlink the heavy arch-independent CUDA libs (cudnn/cublas/nccl/...) into the base venv copy. cuda_nvrtc and cuda_runtime are excluded (the arm64 nvrtc swap mutates nvrtc in place). Also remove the build-only frontend node_modules (runtime serves the committed dist). Studio image drops ~4.8GB. Per-notebook transformers version, run notebooks unchanged: - Bake coherent transformers sidecars (4.57.6 default + 5.3.0/5.5.0/5.10.2), each transformers==X with its matched huggingface_hub/tokenizers/ safetensors installed --no-deps into its own dir. Companion versions are resolved at build time so they satisfy each transformers' requirements. - unsloth_nb_compat.py: pick the sidecar from the notebook's pin or the model name and activate it (prepend to sys.path) before any ML import, without touching the base cu128 torch/vLLM/unsloth stack. - pip/uv shim on PATH: a notebook install cell becomes safe and idempotent inside a kernel (keeps the baked stack, records the requested transformers for its sidecar); passthrough to the real tool everywhere else. - IPython startup hook for manual JupyterLab, and unsloth-run for the headless driven path. --- docker/.dockerignore | 4 + docker/Dockerfile | 98 ++++++++++++++++++++- docker/Dockerfile.studio | 35 +++++++- docker/unsloth_ipython_startup.py | 18 ++++ docker/unsloth_nb_compat.py | 135 +++++++++++++++++++++++++++++ docker/unsloth_pip_shim.py | 136 ++++++++++++++++++++++++++++++ docker/unsloth_run.py | 107 +++++++++++++++++++++++ 7 files changed, 528 insertions(+), 5 deletions(-) create mode 100644 docker/unsloth_ipython_startup.py create mode 100644 docker/unsloth_nb_compat.py create mode 100644 docker/unsloth_pip_shim.py create mode 100644 docker/unsloth_run.py diff --git a/docker/.dockerignore b/docker/.dockerignore index ae1f499a29..1bd005c9c1 100644 --- a/docker/.dockerignore +++ b/docker/.dockerignore @@ -5,3 +5,7 @@ !fetch_llama_prebuilt.py !supervisord.conf !studio_launch.sh +!unsloth_nb_compat.py +!unsloth_pip_shim.py +!unsloth_ipython_startup.py +!unsloth_run.py diff --git a/docker/Dockerfile b/docker/Dockerfile index 2d577d0559..fd3a8d1cdc 100644 --- a/docker/Dockerfile +++ b/docker/Dockerfile @@ -282,10 +282,20 @@ RUN set -eux \ # langid DeepSeek-R1 GRPO reward's language-id check # easydict some vision trust_remote_code modeling files # protobuf slow->fast tokenizer conversion for sentencepiece models +# omegaconf TTS families + both NeMo-Gym RL notebooks' config objects +# einx TTS codec tensor-rearrange (Llasa / Oute / Spark TTS) +# librosa Whisper audio feature extraction (pairs with soundfile + torchcodec) +# decord ERNIE-VL vision notebook video decode +# ftfy Oute TTS text normalisation +# librosa pulls numba/soxr/audioread; numba is already pinned >=0.65 (numpy 2.4 +# compatible) by the vLLM pass, so the resolve must NOT move torch/numpy/numba -- +# the assertion below fails the build loudly if it did.

We record the content hash of every file we write; on refresh a file whose hash differs from what we last wrote is treated as user-modified and is left untouched, so the refresh only updates files the user has not changed and adds new ones. It never overwrites an edited notebook and never produces merge conflicts. Verified: an edited notebook stays the user's version across repeated upstream changes. - Fully best-effort and gated: UNSLOTH_SKIP_NOTEBOOK_SYNC=1 disables it, UNSLOTH_SKIP_NOTEBOOK_REFRESH=1 keeps the baked copy and never hits the network.

Dynamically follow the newest unslothai/llama.cpp release. build.sh resolves the latest release tag (following the /releases/latest redirect, no API token) to a concrete tag and passes it as LLAMA_PREBUILT_TAG, so the layer cache busts only when upstream publishes. The Dockerfile default is now "latest" and fetch_llama_prebuilt.py resolves it the same way, so a plain `docker build .` also tracks latest. Pin LLAMA_PREBUILT_TAG to a concrete tag for a reproducible, frozen build. 2. Make the in-app "newer llama.cpp available" banner work inside the image. Studio's freshness check (utils.llama_cpp_freshness.check_prebuilt_freshness) keys off tag / release_tag / published_repo in UNSLOTH_PREBUILT_INFO.json -- the schema install_llama_prebuilt.py writes. The image bakes the bundle directly, so the marker was the release tarball's own, which only carries upstream_tag / source_repo; the freshness check then bailed with installed_tag=None and could never report "behind", hiding the banner. fetch_llama_prebuilt.py now augments the baked marker with those keys (setdefault, no build timestamp so the layer stays byte-identical). A fresh build is on latest -> no banner; once upstream publishes a newer release the banner appears, as verified against the real freshness backend. --- docker/Dockerfile | 7 ++++- docker/build.sh | 21 ++++++++++++++ docker/fetch_llama_prebuilt.py | 50 +++++++++++++++++++++++++++++++++- 3 files changed, 76 insertions(+), 2 deletions(-) diff --git a/docker/Dockerfile b/docker/Dockerfile index 1dca2799e1..70c910ab1e 100644 --- a/docker/Dockerfile +++ b/docker/Dockerfile @@ -617,7 +617,12 @@ RUN set -eux \ # so the python-side tensor mappings match the binaries # /opt (not /root) so the install survives a `docker run --user` override; # UNSLOTH_LLAMA_CPP_PATH makes zoo find it regardless of $HOME. -ARG LLAMA_PREBUILT_TAG=b9596-mix-e6f2453 +# Default "latest" -> fetch_llama_prebuilt.py resolves the newest +# unslothai/llama.cpp release at build time (follows the /releases/latest +# redirect, no API token). build.sh resolves this to a concrete tag before +# invoking docker build so the layer cache busts only when upstream publishes; +# pass --build-arg LLAMA_PREBUILT_TAG= for a frozen, reproducible build. +ARG LLAMA_PREBUILT_TAG=latest COPY fetch_llama_prebuilt.py /tmp/fetch_llama_prebuilt.py RUN /opt/unsloth-venv/bin/python /tmp/fetch_llama_prebuilt.py \ "${LLAMA_PREBUILT_TAG}" "${TARGETARCH:-amd64}" /opt/unsloth/llama.cpp \ diff --git a/docker/build.sh b/docker/build.sh index 592a52da49..f84aa9f36e 100755 --- a/docker/build.sh +++ b/docker/build.sh @@ -18,10 +18,30 @@ PYTHON_VERSION="${PYTHON_VERSION:-3.12}" UNSLOTH_REF="${UNSLOTH_REF:-main}" UNSLOTH_ZOO_REF="${UNSLOTH_ZOO_REF:-main}" +# llama.cpp prebuilt: default to the newest unslothai/llama.cpp release, resolved +# here to a concrete tag so the build-arg changes only when upstream publishes a +# new release (correct Docker layer caching) and the build stays reproducible. +# Pin it explicitly for a frozen build: LLAMA_PREBUILT_TAG=b9596-mix-e6f2453 ./build.sh +resolve_latest_llama_tag() { + curl -fsSL -o /dev/null -w '%{url_effective}' \ + "https://github.com/unslothai/llama.cpp/releases/latest" 2>/dev/null \ + | sed -n 's#.*/releases/tag/##p' +} +if [ -z "${LLAMA_PREBUILT_TAG:-}" ]; then + LLAMA_PREBUILT_TAG="$(resolve_latest_llama_tag || true)" + if [ -n "$LLAMA_PREBUILT_TAG" ]; then + echo "Resolved latest llama.cpp release: ${LLAMA_PREBUILT_TAG}" + else + LLAMA_PREBUILT_TAG="latest" + echo "Could not resolve latest llama.cpp tag here; passing 'latest' (resolved inside the build)" + fi +fi + echo "Building ${IMAGE_NAME}:${TAG}" echo " CUDA ${CUDA_VERSION} Ubuntu ${UBUNTU_VERSION} Python ${PYTHON_VERSION}" echo " unsloth @${UNSLOTH_REF}" echo " unsloth-zoo @${UNSLOTH_ZOO_REF}" +echo " llama.cpp ${LLAMA_PREBUILT_TAG}" echo " arch list 8.0;8.6;8.9;9.0;10.0;12.0+PTX" echo @@ -32,6 +52,7 @@ DOCKER_BUILDKIT=1 docker build \ --build-arg PYTHON_VERSION="${PYTHON_VERSION}" \ --build-arg UNSLOTH_REF="${UNSLOTH_REF}" \ --build-arg UNSLOTH_ZOO_REF="${UNSLOTH_ZOO_REF}" \ + --build-arg LLAMA_PREBUILT_TAG="${LLAMA_PREBUILT_TAG}" \ -t "${IMAGE_NAME}:${TAG}" \ . diff --git a/docker/fetch_llama_prebuilt.py b/docker/fetch_llama_prebuilt.py index 503723c9cc..3eb50d67a6 100644 --- a/docker/fetch_llama_prebuilt.py +++ b/docker/fetch_llama_prebuilt.py @@ -19,8 +19,13 @@ tensor mappings match the binaries -- the layout unsloth_zoo's check_llama_cpp() expects: binaries, converter and gguf-py/ at the install dir root. +The tag may be the literal "latest" (or empty), in which case the newest +published release of RELEASE_REPO is resolved at build time by following the +/releases/latest redirect (no API token, no API rate limit).

Add a baked helper so a running container can update in place: docker exec unsloth-studio-update It updates only the Studio packages -- the backend code and the pre-built frontend, which ships inside the unsloth wheel -- with `pip install -U --no-deps unsloth unsloth_zoo`, then restarts just the studio service via supervisor. The torch/CUDA stack is left untouched, so it is safe in both GPU and CPU-only containers. This deliberately avoids `unsloth studio update`, which re-runs the full installer and re-probes the GPU to pick torch wheels -- in a container started without --gpus that finds no GPU and can downgrade torch to CPU/cu126. Options: --ref installs from git (track main) instead of the latest PyPI release; --with-deps also updates dependencies; --no-restart defers the restart. After the swap the helper smoke-imports studio.backend.main and, if a transitive dep is now missing, points the user at --with-deps.

The -r value was passed to the real pip unchanged, so torch / transformers / vLLM / nvidia pins inside the file could overwrite the baked cu128 stack or push transformers into the base venv. _filter_requirements_file() applies the same _KEEP / transformers-sidecar rules per line, writes the survivors to a temp file, keeps comments, option lines, nested includes and urls verbatim, and records a pinned transformers version for the sidecar. - install.sh + Dockerfile.studio + docker-publish.yml: forward the resolved unsloth-zoo ref into the Studio build. install.sh --local overlaid unsloth-zoo from git main regardless of the operator-requested or base-image ref, so the full image could run a different zoo than the base. install.sh now honors UNSLOTH_ZOO_REF across all four --local overlays, Dockerfile.studio passes UNSLOTH_STUDIO_ZOO_REF through to it, and the workflow resolves one zoo ref in the prepare job and shares it with both the base and Studio builds. - Dockerfile + docker-publish.yml: pin unslothai/notebooks to one resolved commit. Each arch leg cloned HEAD independently, so the same tag could seed different baked templates and .unsloth_template_commit depending on the pulled platform. The prepare job freezes notebooks to one sha (like the llama.cpp prebuilt tag) and the Dockerfile fetches that single ref at depth 1. --- .github/workflows/docker-publish.yml | 95 ++++++++++++++++++++-------- docker/Dockerfile | 14 +++- docker/Dockerfile.studio | 6 ++ docker/unsloth_pip_shim.py | 69 ++++++++++++++++++-- install.sh | 34 ++++++---- 5 files changed, 173 insertions(+), 45 deletions(-) diff --git a/.github/workflows/docker-publish.yml b/.github/workflows/docker-publish.yml index d68f7c1889..e86fec2790 100644 --- a/.github/workflows/docker-publish.yml +++ b/.github/workflows/docker-publish.yml @@ -48,6 +48,10 @@ on: description: 'unslothai/llama.cpp prebuilt release tag to bake (blank = newest)' required: false default: '' + notebooks_ref: + description: 'unslothai/notebooks git ref to bake (resolved to one commit)' + required: false + default: 'main' env: REGISTRY: docker.io @@ -85,6 +89,12 @@ jobs: contents: read outputs: llama_tag: ${{ steps.llama.outputs.tag }} + # One zoo ref + one notebooks commit, resolved here so BOTH arch legs of + # the base build (and the Studio build) bake the identical bits.

JupyterLab labextension (prebuilt in a throwaway builder stage, so the runtime image stays Node-free): - Unsloth Dark (Monokai) theme, adaptive light/dark by system preference - Colab-style ArrowDown/Up cell navigation - top-bar Unsloth logo (stock Jupyter logo disabled and locked) - #@title lines render as collapsible Heading-2 form bars - Ctrl+A in a cell output selects only that output, not the whole notebook (the old behaviour ran notebook:select-all and was laggy) - right activity bar hidden by default - overrides.json: per-cell run button without auto-advance, labeled Restart and Run All, windowing off so collapsing an output does not snap to the cell top, news/update prompts suppressed Studio and login branding: Unsloth favicon, page logo, and a dark Unsloth login page that rotates through the curated Studio sloth stickers (fail-soft to the logo). Notebook organization and Colab compatibility (base image): - categorized folder view built from relative symlinks mirroring the README sections, rebuilt each boot; real .ipynb files never moved, and the symlink tree is invisible to the sync state machine - AMD-* notebooks shown only on an AMD/HIP host (autodetected) - Docker-only strip of the Colab "Run all on Colab" intro sentence from unedited notebooks (upstream notebooks unchanged) - hoist %%capture above a leading #@title form so the cell runs - the per-cell transformers-sidecar log is silent unless UNSLOTH_ENABLE_LOGGING=1 Dependency pinning and naming: the curated notebook extras are pinned to their resolved versions for reproducible rebuilds; decord is split into its own fail-soft install (no aarch64 wheel). The lean base image is renamed from :base to :core. Adds tests/validate_studio_features.py, a static self-test for the labextension plugins, overrides keys, and branding wiring. * [pre-commit.ci] auto fixes from pre-commit.com hooks for more information, see https://pre-commit.ci * docker: address review feedback on the JupyterLab/Studio UX - unsloth_nb_view.py: rebuilding the categorized view no longer deletes user files. The view is also JupyterLab's landing dir, so a user may save real notebooks there; _clear_view now unlinks only the symlinks we own and removes only folders that end up empty, leaving regular files in place. It also tests islink before isdir, so a view that is itself a symlink to a directory is unlinked instead of being walked into (which would have wiped the symlink target). - studio_launch.sh: derive the landing URL and preferred_dir from UNSLOTH_NOTEBOOKS_VIEW_DIR / UNSLOTH_SKIP_NOTEBOOK_VIEW, the same env the sync script uses, instead of hard-coding /workspace/Unsloth Notebooks. A relocated or disabled view no longer opens JupyterLab on a missing folder; it falls back to the default /lab over /workspace. - Dockerfile.studio: the labext-builder stage now installs Node 20 from NodeSource. Ubuntu 24.04's distro nodejs is 18, below JupyterLab 4.6's declared Node >=20 engine. Node stays confined to the throwaway builder stage, so the runtime image is unchanged. - .dockerignore: explicitly allowlist jupyter/install_sloth_stickers.py alongside its sibling jupyter assets, rather than relying on the directory re-inclusion. * [pre-commit.ci] auto fixes from pre-commit.com hooks for more information, see https://pre-commit.ci * docker: publish lean image as :core and full image as :studio Complete the base->core (and "studio as studio") tag rename so the publish workflow matches the user-facing helpers and the Dockerfile.studio header. - The lean training image now publishes as :core (core-, core-nightly, core-sha-*); run.sh / docker_confirm.* already told users to pull :core, but docker-publish.yml still tagged it :base, so that pull would have 404'd. The per-arch digest artifacts are renamed to match. - The full Studio image keeps :latest and gains a stable :studio alias, matching the Dockerfile.studio header. Both the merge and post-publish smoke-test metadata blocks are updated together. Internal "base image" wording (the layer Studio builds FROM) is left as-is. * docker: address second-round review feedback on the JupyterLab/Studio UX - studio_launch.sh: also gate the categorized-view landing URL on UNSLOTH_SKIP_NOTEBOOK_SYNC (the entrypoint skips building the view entirely in that mode), not just UNSLOTH_SKIP_NOTEBOOK_VIEW, so a no-sync container does not land on a missing folder. - Dockerfile.studio: scope the sticker-install "|| echo" fallback to only the sticker step via a { ...; } group. It was attached to the whole branding && chain, so a failure in a REQUIRED step (JS resolve, favicon/logo/login copy) was swallowed and the build continued with broken branding. - unsloth_nb_view.py: when creating the categorized symlinks, only replace our own stale symlinks; if a real user file already occupies that name, keep it and skip the link instead of os.remove-ing it. - overrides.json: drop doNotDisturbMode (it silenced ALL JupyterLab toasts, including kernel-restart / connection-drop feedback). The news/update prompts are already off via fetchNews / checkForUpdates. - Dockerfile: keep decord mandatory on amd64 (fail the build on a missing or incompatible wheel) and only fail-soft on arm64/other arches that have no wheel. - cellNav.ts: do not hijack ArrowUp/Down when focus is in an interactive output widget / form control, or while a completion popup is open, so ipywidgets controls and autocomplete at cell boundaries keep working. * [pre-commit.ci] auto fixes from pre-commit.com hooks for more information, see https://pre-commit.ci * docker: keep Studio branding RUN free of comments inside the line continuation Move the sloth-sticker fail-soft explanation above the RUN so no comment line sits between backslash-continued commands. BuildKit strips such comments, but keeping the RUN body a plain && chain removes the ambiguity for non-BuildKit builders and static linters. The { ...; } fail-soft scoping is unchanged. * [pre-commit.ci] auto fixes from pre-commit.com hooks for more information, see https://pre-commit.ci * docker: AGPLv3 attribution + integrity guard for the Studio/JupyterLab image Make it obvious the image is built by Unsloth and hard to white-label out with a shallow find-and-replace, and surface the AGPLv3 license + copyright in the UI. Visible attribution (labextension): - Help > "About Unsloth Docker Studio" dialog (about.ts): Unsloth logo, the AGPLv3 notice, "Copyright 2026-Present the Unsloth team", and source/website/ license links. Added to the Help menu and the command palette. - The JupyterLab loading splash is replaced with a spinning Unsloth logo (splash.ts, provides ISplashScreen; honors prefers-reduced-motion). The stock @jupyterlab/apputils-extension:splash is disabled+locked at build time, like the stock logo. - AGPLv3 footer (license + copyright + links) on the branded login page. - Labextension relicensed AGPL-3.0-only; SPDX headers on every source file. Anti-tamper (no encoded/obfuscated strings -- plain readable text only; the one data URI is the logo image): - A canonical, plain-text attribution set lives in unsloth_branding.py with a TypeScript mirror (branding.ts) bundled verbatim into the labextension, so the phrase, copyright, links and plugin ids are spread across independent layers. - unsloth_branding.py verifies all of these across the installed files (AGPLv3 text, login footer, theme, labextension package + built bundle strings, logo, favicon) and fails loudly if any are missing. It runs at three layers: build time (fails the image build), the whole-container launcher (studio_launch.sh refuses to start), and as a jupyter_server extension (refuses to serve JupyterLab). - tests/studio/test_branding_guard.py: positive + per-marker negative coverage, plus a check that no base64/decoder obfuscation crept into the attribution. * [pre-commit.ci] auto fixes from pre-commit.com hooks for more information, see https://pre-commit.ci * docker: address #6681 review round 2 (colab magics, output select, branding guard) - unsloth_colab_compat.py: only hoist a leading `%%` cell magic above the Colab `#@title` form for magics whose body runs as code (capture/time/bash/python/ ...). Content magics (%%writefile, %%html, %%latex, ...) are left untouched so the form comment is never injected into the written file / rendered output. - outputSelect.ts: stop trusting the text selection anchor to decide ownership of Ctrl/Cmd+A. A stale selection inside an output survives a click onto a command-mode cell or the file browser, which made select-all keep re-selecting the old output. Gate on the keystroke target or the last pointer-down (reset to null on any click outside an output) instead. - unsloth_branding.py: also reject page_config.json that disables the Unsloth labextension or any of its plugin ids via disabledExtensions (dict or list form); that leaves the bundle on disk so the prior checks passed while the logo/About/splash attribution was stripped at load. Lock unsloth-jupyterlab in Dockerfile.studio as well (defense in depth), and add guard tests. * [pre-commit.ci] auto fixes from pre-commit.com hooks for more information, see https://pre-commit.ci * labext: pin JupyterLab extension deps; confirm.ps1 /login probe Pin the unsloth-jupyterlab npm deps to exact versions matching the baked jupyterlab==4.6.0 (builder stays 4.5.9, its newest release) instead of floating ^/~ ranges, so the same commit always builds the same labextension bundle. Also probe JupyterLab /login (not /api, which 403s behind a password hash) in the Windows confirmation script. * docker: categorize AMD/domain notebooks and wire the feature validation into CI unsloth_nb_view.parse_readme only reset the folder section on level-3 (###) headings. The notebooks README carries level-1 domain headers (# AMD Notebooks, # Kaggle Notebooks) with their own nb/*.ipynb link tables and no intervening ###, so those notebooks were mis-filed under the previous stale section (all 148 AMD notebooks landed in Other Notebooks on an --amd build). Reset on any heading level and strip a leading emoji/symbol run so the domain notebooks get their own clean folder. Also run tests/validate_studio_features.py explicitly in the repo CPU job. It is named validate_* (not test_*) so pytest never collected it, which meant a regression in the notebook view, Colab compat, strip, JupyterLab defaults or login branding failed CI only when run by hand. * labext: use caret ranges so jlpm dedups JupyterLab/Lumino singletons The exact pins introduced earlier (@jupyterlab/* 4.6.0, @lumino/widgets 2.8.0, @jupyterlab/builder 4.5.9) break the Dockerfile.studio labext-builder stage. Exact-pinning the framework packages defeats jlpm's (yarn classic) hoisting: transitive @jupyterlab deps request caret ranges that resolve to newer patch releases (e.g. @jupyterlab/ notebook pulls @jupyterlab/cells ^4.6.0 -> a newer patch), so jlpm installs a second nested copy alongside the exact top-level one. Two copies of @jupyterlab/cells and @lumino/widgets in the tree produce TS2345 "not assignable" errors (protected-member/identity mismatch) and the build fails. Caret ranges let jlpm collapse every @jupyterlab and @lumino package to a single hoisted copy, which is required for a JupyterLab prebuilt (federated) extension: at runtime those packages are shared singletons provided by the host JupyterLab, so the build-time versions only need to type-check against one consistent tree, not match an exact runtime patch. This is the version set the published image was built and validated with end to end. Verified by building the labext in isolation against the base image (Node 20 + bundled jlpm): caret ranges build clean (webpack compiled successfully); the exact pins fail with the duplicate-package TS errors. * ci(studio-backend): trigger on docker/** so the JupyterLab feature validation guards docker-only changes The 'Docker JupyterLab/notebook feature validation' step runs tests/validate_studio_features.py, which checks docker/jupyter (the labextension, overrides.json, login branding) and the docker notebook helpers. The pull_request paths filter listed studio/unsloth/tests but not docker/**, so a PR that only touches docker/ would skip that step and a regression in those files could pass CI. Add docker/** so the validation runs whenever the files it checks change. * jupyter: center the login card and place the attribution below it #site was a flex container using the default row direction with two children (the login card and the AGPLv3 attribution), so they rendered side by side: the card sat left of centre and the attribution floated up to the top-right. Stack them in a column so the card is horizontally centred and the attribution sits below it as a footer, matching the intended single-column layout. * jupyter: refresh Studio attribution, About dialog and loading splash - Attribution now reads 'Built by the Unsloth team' with a single Apache 2.0 / AGPLv3 license link (to the repo license section) on the login page and in the About dialog, replacing the plain 'Built by Unsloth. Licensed under the GNU AGPLv3.' line. The integrity guard, its canonical PHRASE and the branding tests are updated to match. - About dialog: left-align the link rows so the labels line up instead of each row centering independently; add an 'Unsloth Reference' link to the docs, and a Licenses section listing Unsloth Studio (AGPLv3) and Unsloth Core (Apache 2.0) alongside the full license link. - Loading splash now reads 'Loading Unsloth Docker' instead of the attribution label, via a dedicated SPLASH_LABEL constant. * docker: document the branding attribution as an AGPLv3 Section 7 notice Add docker/NOTICE and docker/jupyter/BRANDING.md so the Unsloth attribution that unsloth_branding.py enforces is also a written license condition, not only a build check. docker/NOTICE designates the attribution (the "Built by the Unsloth team" label, the copyright line, the license notice, the logo and theme, and the Help > About links) as required Appropriate Legal Notices under AGPLv3 Section 7(b), referencing /studio/LICENSE.AGPL-3.0 and /LICENSE. BRANDING.md is a human-readable note next to the guard describing what must stay, where it lives and how it is enforced. * ci(studio-backend): restore docker/** trigger path The docker/** pull_request path added in b558bc7d was dropped by a later rebase, so the "Docker JupyterLab/notebook feature validation" step (which runs tests/validate_studio_features.py against docker/jupyter branding and notebook helpers) no longer ran on PRs that only touch docker/. Re-add docker/** so a docker-only change is validated on the PR rather than only after merge to main. --------- Co-authored-by: pre-commit-ci[bot] <66853113+pre-commit-ci[bot]@users.noreply.github.com> --- .github/workflows/docker-publish.yml | 35 +- .github/workflows/studio-backend-ci.yml | 11 + docker/.dockerignore | 20 ++ docker/Dockerfile | 9 +- docker/Dockerfile.studio | 90 +++++- docker/NOTICE | 41 +++ docker/docker_confirm.ps1 | 2 +- docker/docker_confirm.sh | 4 +- docker/jupyter/BRANDING.md | 50 +++ docker/jupyter/favicon.ico | Bin 0 -> 16901 bytes docker/jupyter/install_sloth_stickers.py | 78 +++++ .../unsloth_branding_guard.json | 7 + docker/jupyter/login.html | 118 +++++++ docker/jupyter/logo.png | Bin 0 -> 14416 bytes docker/jupyter/overrides.json | 40 +++ docker/jupyter/unsloth_branding.py | 305 ++++++++++++++++++ docker/jupyter/unsloth_labext/.gitignore | 7 + docker/jupyter/unsloth_labext/.yarnrc.yml | 1 + docker/jupyter/unsloth_labext/package.json | 54 ++++ docker/jupyter/unsloth_labext/src/about.ts | 98 ++++++ docker/jupyter/unsloth_labext/src/branding.ts | 30 ++ docker/jupyter/unsloth_labext/src/cellNav.ts | 126 ++++++++ .../jupyter/unsloth_labext/src/colabTitle.ts | 161 +++++++++ docker/jupyter/unsloth_labext/src/index.ts | 81 +++++ docker/jupyter/unsloth_labext/src/logo.ts | 8 + .../unsloth_labext/src/outputSelect.ts | 136 ++++++++ docker/jupyter/unsloth_labext/src/splash.ts | 89 +++++ docker/jupyter/unsloth_labext/src/uiChrome.ts | 60 ++++ docker/jupyter/unsloth_labext/style/index.css | 6 + .../unsloth_labext/style/variables.css | 97 ++++++ docker/jupyter/unsloth_labext/tsconfig.json | 26 ++ docker/run.sh | 4 +- docker/studio_launch.sh | 38 +++ docker/unsloth_colab_compat.py | 101 ++++++ docker/unsloth_ipython_startup.py | 10 + docker/unsloth_nb_compat.py | 16 +- docker/unsloth_nb_strip_colab.py | 216 +++++++++++++ docker/unsloth_nb_view.py | 245 ++++++++++++++ docker/unsloth_sync_notebooks.sh | 74 +++++ tests/studio/test_branding_guard.py | 252 +++++++++++++++ tests/validate_studio_features.py | 279 ++++++++++++++++ 41 files changed, 2997 insertions(+), 28 deletions(-) create mode 100644 docker/NOTICE create mode 100644 docker/jupyter/BRANDING.md create mode 100644 docker/jupyter/favicon.ico create mode 100644 docker/jupyter/install_sloth_stickers.py create mode 100644 docker/jupyter/jupyter_server_config.d/unsloth_branding_guard.json create mode 100644 docker/jupyter/login.html create mode 100644 docker/jupyter/logo.png create mode 100644 docker/jupyter/overrides.json create mode 100644 docker/jupyter/unsloth_branding.py create mode 100644 docker/jupyter/unsloth_labext/.gitignore create mode 100644 docker/jupyter/unsloth_labext/.yarnrc.yml create mode 100644 docker/jupyter/unsloth_labext/package.json create mode 100644 docker/jupyter/unsloth_labext/src/about.ts create mode 100644 docker/jupyter/unsloth_labext/src/branding.ts create mode 100644 docker/jupyter/unsloth_labext/src/cellNav.ts create mode 100644 docker/jupyter/unsloth_labext/src/colabTitle.ts create mode 100644 docker/jupyter/unsloth_labext/src/index.ts create mode 100644 docker/jupyter/unsloth_labext/src/logo.ts create mode 100644 docker/jupyter/unsloth_labext/src/outputSelect.ts create mode 100644 docker/jupyter/unsloth_labext/src/splash.ts create mode 100644 docker/jupyter/unsloth_labext/src/uiChrome.ts create mode 100644 docker/jupyter/unsloth_labext/style/index.css create mode 100644 docker/jupyter/unsloth_labext/style/variables.css create mode 100644 docker/jupyter/unsloth_labext/tsconfig.json create mode 100644 docker/unsloth_colab_compat.py create mode 100644 docker/unsloth_nb_strip_colab.py create mode 100644 docker/unsloth_nb_view.py create mode 100644 tests/studio/test_branding_guard.py create mode 100644 tests/validate_studio_features.py diff --git a/.github/workflows/docker-publish.yml b/.github/workflows/docker-publish.yml index 18a8d4de0a..6682e09113 100644 --- a/.github/workflows/docker-publish.yml +++ b/.github/workflows/docker-publish.yml @@ -274,7 +274,7 @@ jobs: - name: Upload digest uses: actions/upload-artifact@v4 with: - name: digests-base-${{ matrix.platform == 'linux/amd64' && 'amd64' || 'arm64' }} + name: digests-core-${{ matrix.platform == 'linux/amd64' && 'amd64' || 'arm64' }} path: /tmp/digests/* if-no-files-found: error retention-days: 1 @@ -301,7 +301,7 @@ jobs: - uses: actions/download-artifact@v4 with: path: /tmp/digests - pattern: digests-base-* + pattern: digests-core-* merge-multiple: true - uses: docker/setup-buildx-action@v3 @@ -322,17 +322,17 @@ jobs: # and collide with the Studio image that legitimately owns :latest. flavor: latest=false tags: | - # The lean training image publishes under the base- prefix;

The old extra pulls xformers 0.0.34, which hard-pins torch==2.10.0 and conflicts with the torch==2.11.0 held throughout the build; the torch2110 family pulls xformers 0.0.35 (no torch pin) and resolves cleanly. This needs an unsloth carrying the torch2110 CUDA extras on main, so merge the torch2110 extras PR first (default UNSLOTH_REF=main). - notebook-deps assertion: startswith('2.10.0') -> '2.11.0' so the layer actually verifies the torch it now installs. - refresh the torch2100/xformers 0.0.34 references in the surrounding comments to the torch2110/0.0.35 line. sm_103 (B300/GB300) JIT override (Codex item): The cu13 NVRTC/ptxas override was arm64-only (sm_121), and its comment claimed triton 3.6.0 bundles cu13 ptxas and set TRITON_PTXAS_PATH -- neither was true: triton 3.6.0's bundled ptxas is CUDA 12.8 (V12.8.93, tops out at sm_120) and TRITON_PTXAS_PATH was never set. So sm_103 (amd64) and even sm_121 (arm64) Triton JIT were unfixed. Run the cu13 install on both arches and actually wire the ptxas override: - NVRTC swap (cu13 libnvrtc.so.13 over torch's bundled cu12.8 .so.12) now runs on amd64 too. - ENV TRITON_PTXAS_PATH=/usr/local/cuda-13.0/bin/ptxas routes every Triton JIT through the cu13 ptxas. Global rather than per-arch is safe: cu13.0 ptxas spans sm_70..sm_121 (verified: Volta/Turing/Ampere/Hopper through Blackwell), so no regression for the older GPUs in the arch list. Verified on amd64 in the built base image: cuda-nvrtc-13-0/cuda-nvcc-13-0 install cleanly from the base's CUDA repo, ptxas lands at /usr/local/cuda-13.0/bin/ptxas (V13.0.88) and libnvrtc.so.13 at /usr/local/cuda-13.0/lib64/. The sm_103/sm_121 runtime path itself is not hardware-tested (no such GPU on hand); precompiled SASS still covers both via sm_100/sm_120 forward-compat, so only JIT-heavy paths rely on this. --- docker/Dockerfile | 93 +++++++++++++++++++++++++---------------------- 1 file changed, 50 insertions(+), 43 deletions(-) diff --git a/docker/Dockerfile b/docker/Dockerfile index 9c3c7306fa..96b83aafc8 100644 --- a/docker/Dockerfile +++ b/docker/Dockerfile @@ -17,10 +17,10 @@ # * Unsloth's runtime kernels are Triton, which JIT-compiles per device at # first run.

That is only safe when both venvs run the same torch, but the pre-dedup guard only checked the CUDA family (endswith('+cu128')). A Studio venv that installed torch 2.10.0+cu128 (an installer capped below the base's 2.11.0, or a build-time nvidia-smi fallback) would pass that check yet mismatch the base's 2.11.0+cu128, and the dedup would link incompatible libs. Capture the base venv's torch from its metadata and assert the Studio venv torch equals it exactly (version and family) before the dedup runs, so a mismatch fails the build loudly instead of silently linking skewed CUDA libs. Comparing to the base venv also avoids hardcoding the version here. The Studio venv reaches torch 2.11.0+cu128 via the installer's UNSLOTH_TORCH_INDEX_FAMILY=cu128 handling and its CUDA torch spec allowing 2.11.x. --- docker/Dockerfile.studio | 18 ++++++++++++------ 1 file changed, 12 insertions(+), 6 deletions(-) diff --git a/docker/Dockerfile.studio b/docker/Dockerfile.studio index d6480704f3..2f51481830 100644 --- a/docker/Dockerfile.studio +++ b/docker/Dockerfile.studio @@ -136,12 +136,18 @@ RUN set -eux \ UNSLOTH_ZOO_REF="${UNSLOTH_STUDIO_ZOO_REF}" \ UNSLOTH_PYTHON=3.12 \ bash install.sh --local \ - # Fail loud if the Studio venv torch missed the pinned CUDA family (an - # install.sh that ignores UNSLOTH_TORCH_INDEX_FAMILY falls back to - # nvidia-smi probing, which cannot work at build time and lands on cu126 - # wheels with no sm_100/sm_120 kernels). metadata check only: importing - # torch needs native libs, which QEMU arm64 builds cannot load. - && "${UNSLOTH_STUDIO_HOME}/unsloth_studio/bin/python" -c "import sys; from importlib.metadata import version; assert sys.version_info[:2] == (3, 12), 'Studio venv python %d.%d is not 3.12 (UNSLOTH_PYTHON pin ignored) -- CUDA dedup below depends on it' % sys.version_info[:2]; v = version('torch'); assert v.endswith('+${TORCH_FAMILY}'), 'Studio venv torch ' + v + ' does not match ${TORCH_FAMILY}'; print('Studio venv python %d.%d' % sys.version_info[:2], 'torch', v)" \ + # Fail loud unless the Studio venv torch EXACTLY matches the base venv + # torch (version AND CUDA family) before the dedup below symlinks the two + # venvs' CUDA libs together.

UNSLOTH_REF / UNSLOTH_STUDIO_REF were raw expressions re-evaluated per base arch leg and in the Studio build, so a mutable branch (the workflow_dispatch default unsloth_ref=main) advancing during the run could bake different unsloth commits under one manifest. Resolve once (same precedence: dispatch input, else pushed tag, else triggering sha, else main; ls-remote a branch/tag to a sha, mirroring the zoo/notebooks steps) and read needs.prepare.outputs.unsloth_ref everywhere. Dockerfile.studio: run the Studio venv NVRTC cu13 swap on both arches, not arm64 only. amd64 sm_103 (B300/GB300) needs cu13 NVRTC just as arm64 sm_121 does, and the CUDA dedup never touches cuda_nvrtc, so an amd64 Studio venv would otherwise keep its bundled cu12.8 libnvrtc and fail NVRTC/jiterator JIT on compute_103. The base cu13 layer installs cuda-nvrtc-13-0 on both arches, so the target .so.13 exists here regardless of TARGETARCH. unsloth_pip_shim.py: close three ways a protected package slipped past _KEEP. Treat -e/--editable as a value-taking flag paired with its target and drop both when the target is protected (was leaving a dangling -e that failed the cell); filter -P/--upgrade-package values through _KEEP (a named baked package could be refreshed while installing another target); and parse the PEP 427 distribution name out of a wheel URL/path so a bare `pip install https://.../torch-...whl` drops instead of reinstalling the baked torch. Non-protected editables, upgrade selectors, and wheels are unchanged.

An editable line (-e/--editable ) inside a -r requirements file is a real install target, so a protected editable there is now classified and dropped like the command-line case (new _parse_editable). pip/uv accept the attached short forms -rreqs.txt / -cconstraints.txt / -epath / -Pname as one token; these were falling through as opaque options (so an attached -r-only cell no-op'd and an attached -c/-e/-P value bypassed _KEEP), so the 2-char flag is now split from its value and routed through the separated-form handling. And a nested -c constraint inside a -r file no longer records its transformers pin as an install request (a constraint is not a request; mirrors the top-level -c path). entrypoint.sh / Dockerfile: gate the CUDA 13 ptxas + NVRTC to sm_103 / sm_121 at runtime instead of a global build-time default. A cu13 cubin needs a >= 580 driver to LOAD even when it targets an older arch (CUDA has forward, not backward, cross-major driver compatibility), but the image supports Turing.. sm_120 on a 570+ driver, so the previous global TRITON_PTXAS_PATH ENV + cu13 NVRTC symlink would break ordinary Triton/NVRTC JIT on 570-579 driver hosts. The build still bakes cu13 (saving the cu12.8 NVRTC as .cu128.orig); a new select_cuda_jit_tools() in the entrypoint reads the device compute_cap and only activates cu13 for sm_103/sm_121 (which ship >= 580 drivers), otherwise leaving Triton on its bundled cu12.8 ptxas and restoring the cu12.8 NVRTC in both the base and Studio venvs. The base ENTRYPOINT runs for the Studio image too.

Copy to a temp sibling and publish with one atomic rename; dst.exists() is now a truthful complete-tree signal. 2. unsloth_run.py --out truncated the existing output before nbconvert ran, so a timeout, missing kernel, or failed cell irreversibly destroyed the previous result. The input copy and executed result are staged as temp files next to the destination and published with os.replace only on exit code 0. 3. unsloth_nb_view.py cleanup treated every symlink in the view as its own: user-created links (and an operator's view-root routing symlink) were deleted on every rebuild. Cleanup now removes only links that resolve into the notebooks tree it links from, and builds inside a view-root symlink's target instead of unlinking it. 4. unsloth_llama_update.sh: the unconditional EXIT trap deleted the .old backup even when it was the only remaining copy (signal between the two renames, or a failed swap whose restore also failed). The handler now restores the backup first when the install dir is missing and removes it only after the new tree is verifiably active; HUP/INT/TERM route through the same handler. 5. unsloth_pip_shim.py: transitive dependencies could replace the baked torch stack (reproduced with a wheel requiring torch==99.0). Every forwarded install now carries a constraints file pinning the installed protected set, turning the swap into ResolutionImpossible. 6. unsloth_pip_shim.py: ${UPPER} env references in requirements files were classified before pip expanded them, bypassing the protected-package filter; the shim now expands with pip's exact regex first. 7. unsloth_pip_shim.py: a failure writing the filtered requirements copy returned the ORIGINAL file, forwarding exactly the protected pins it had detected; it now fails closed. 8. docker-publish.yml: workflow_dispatch defaulted unsloth_ref to 'main' while the stable-tag gates require '', so UI-default manual runs could never advance :core/:latest/:studio; the default is now empty. 9. entrypoint.sh: the sm_103/sm_121 branch rewrote libnvrtc.so.12 to the CUDA-13 build but the ordinary-GPU branch never restored it, so a container moved to an older GPU kept the stale link; it is now reversed when it points exactly at the .cu13 target. Rejected after verification (no code change): timeout=0 semantics are documented at the site with no zero callers, TORCHINDUCTOR_COMPILE_THREADS override is deliberate, fetchNews is a string enum per JupyterLab's schema, :base tag appears in no in-tree doc, install-cell digest exclusion is the module's stated contract, transformers ceiling semantics are documented, and the cloudflared download mirrors the pre-existing Studio downloader (Cloudflare publishes no checksum asset). The UNSLOTH_ALLOW_CPU import crash lives in unsloth_zoo (compiler.py / loss_utils.py capability probes), not in this diff; the image consumes the zoo fix automatically once merged there. Tests: shim suite extended to 63 (constraints, env expansion, fail-closed), jit-selector suite to 14 (NVRTC reversal transitions), plus staged-publish and ownership repros; wider studio install suite green except failures reproduced at the unmodified head. --- .github/workflows/docker-publish.yml | 21 +++-- docker/entrypoint.sh | 25 ++++-- docker/unsloth_llama_update.sh | 29 ++++++- docker/unsloth_nb_view.py | 61 ++++++++----- docker/unsloth_pip_shim.py | 76 ++++++++++++++-- docker/unsloth_run.py | 49 ++++++++--- studio/install_llama_prebuilt.py | 21 ++++- tests/python/test_unsloth_pip_shim.py | 116 ++++++++++++++++++++++++- tests/sh/test_select_cuda_jit_tools.sh | 14 ++- 9 files changed, 349 insertions(+), 63 deletions(-) diff --git a/.github/workflows/docker-publish.yml b/.github/workflows/docker-publish.yml index e2cce67c52..9371d8e0d2 100644 --- a/.github/workflows/docker-publish.yml +++ b/.github/workflows/docker-publish.yml @@ -37,9 +37,14 @@ on: workflow_dispatch: inputs: unsloth_ref: - description: 'unsloth git ref to bake in' + # Blank means "the dispatched branch" (the resolver below falls back to + # the triggering sha, then main).

Names match exactly after normalization, so a user dir named my-torch-utils is untouched, and a metadata-less directory still passes through. 2. unsloth_nb_pip_magic.py only rewrote literal `!python -m pip`, so the `!{sys.executable} -m pip ...` form notebooks use to target the running kernel (and absolute interpreter paths) bypassed the PATH shim entirely. Input transformers see the raw cell text before IPython expands the braces, so the matcher now also covers {sys.executable} (quoted or bare) and quoted/bare interpreter paths ending in python[0-9.]*(.exe) before -m pip|uv. 3. unsloth_pip_shim.py did not strip uv's --exact, which performs an exact sync that removes every installed package outside the kept target's closure (vLLM, bitsandbytes, the NVIDIA libs); `uv pip install --exact peft` would strip the baked stack after the filter kept it. --exact now joins the resolver-wide destructive flags dropped in shim mode. 4. entrypoint.sh: the arm64 image bakes a CUDA 13 llama.cpp because upstream (unslothai/llama.cpp) publishes no CUDA 12 arm64 asset, while the torch stack (cu128) runs on a 570-series driver. A CUDA 13 cubin cannot load on a 570-579 driver, so on GH200/GB200 hosts below 580 GGUF export and Studio chat fail while training works. The entrypoint now warns up front on aarch64 + driver < 580 instead of letting llama-server fail later.

Comments that pointed at the removed dev scripts now name the underlying command or artifact instead. Non-comment lines of both Dockerfiles and the workflow are byte-identical. unsloth_sync_notebooks.sh folds the three copies of the override -> PATH -> sibling helper resolution into one resolve_helper(), behavior verified for all four modes including graceful absence under set -u. unsloth_pip_shim.py collapses an if/else whose branches were identical and merges the structurally duplicate _parse_include/_parse_editable into one _parse_flag_line. The test suite folds 35 near-duplicate tests into 8 parametrized groups with exact case-count parity (69 collected before and after, 81 passing including the nb-pip-magic suite). Cuts another 144 lines with zero behavior change outside the two refactors. --- .github/workflows/docker-publish.yml | 80 ++----- docker/Dockerfile | 95 +++----- docker/Dockerfile.studio | 15 +- docker/unsloth_pip_shim.py | 61 ++--- docker/unsloth_sync_notebooks.sh | 71 ++---- tests/python/test_unsloth_pip_shim.py | 328 +++++++++++--------------- 6 files changed, 253 insertions(+), 397 deletions(-) diff --git a/.github/workflows/docker-publish.yml b/.github/workflows/docker-publish.yml index f568689c1e..6288d59a7d 100644 --- a/.github/workflows/docker-publish.yml +++ b/.github/workflows/docker-publish.yml @@ -80,12 +80,15 @@ permissions: jobs: # --------------------------------------------------------------------------- - # Resolve the llama.cpp prebuilt release ONCE, up front, so both arch legs of - # the base build bake the identical GGUF binaries.

The pip shim's _VALUE_FLAGS now covers every value-taking flag of uv pip install and pip install (generated from both tools' --help). The separated form `uv pip install --torch-backend cu128 torch` used to drop the protected torch but exec uv with no install target at all (uv hard-errors) instead of no-oping like the attached `=` form, and `--extra torch peft` misread the extra name as a protected target, leaving a dangling --extra that swallowed peft. Adds parametrized regressions plus help-derived drift guards so a future uv/pip value flag cannot silently reintroduce the misparse. unsloth-llama-update now detects when the install dir is itself a mount point (the documented -v unsloth_llama:/opt/unsloth/llama.cpp persistence recipe, where rename(2) fails EBUSY) and swaps the bundle CONTENTS inside the mounted tree, so the update lands in the volume and stays persistent. Work and backup dirs live under the mount (same-fs renames), the abort trap restores the old contents even mid-swap, and the non-mounted path keeps the whole-dir rename. Verified: in-place swap preserves the dir inode and ownership marker, failed fetch leaves the install untouched, simulated mid-swap abort restores fully. --- docker/entrypoint.sh | 12 ++++ docker/unsloth_llama_update.sh | 91 ++++++++++++++++++++++----- docker/unsloth_pip_shim.py | 54 ++++++++++++++++ tests/python/test_unsloth_pip_shim.py | 80 +++++++++++++++++++++++ 4 files changed, 222 insertions(+), 15 deletions(-) diff --git a/docker/entrypoint.sh b/docker/entrypoint.sh index 36138dcfd3..085dbe2b65 100755 --- a/docker/entrypoint.sh +++ b/docker/entrypoint.sh @@ -229,6 +229,18 @@ if major < 7 or (major == 7 and minor < 5): if major < 8: print(f"NOTE: {name} is Turing (sm_{major}{minor}) -- bfloat16 is not supported.") print(" Unsloth will fall back to fp16.

Both arches now take the plain huggingface extra and amd64 pins xformers==0.0.35 explicitly in the same resolve (it requires torch>=2.10 without an exact pin, pairing with the baked 2.11.0; verified on PyPI, x86_64 wheels only, matching the arm64 exclusion). This decouples the base image from the pending extras PR. The Studio build now receives the SAME llama.cpp tag the base image baked: Dockerfile.studio grows a LLAMA_PREBUILT_TAG arg exported as UNSLOTH_LLAMA_TAG to install.sh (setup.sh honours it; the "latest" default is byte-identical to setup.sh's own default for local builds), and the publish workflow forwards the prepare job's resolved tag in the studio build-args. Without the pin a dispatch override or an upstream release landing between the two jobs let the no-GPU Studio build re-resolve "latest" and replace the pinned CUDA bundle. The Studio venv-match assertion also needs installer support for torch 2.11 on the CUDA path; that lands in a separate installer PR and is now declared as a merge-order dependency in the PR description (the publish workflow only runs on main pushes, so nothing builds before both are merged). --- .github/workflows/docker-publish.yml | 10 ++++++---- docker/Dockerfile | 28 +++++++++++++--------------- docker/Dockerfile.studio | 7 +++++++ 3 files changed, 26 insertions(+), 19 deletions(-) diff --git a/.github/workflows/docker-publish.yml b/.github/workflows/docker-publish.yml index 6288d59a7d..8a661d7807 100644 --- a/.github/workflows/docker-publish.yml +++ b/.github/workflows/docker-publish.yml @@ -438,14 +438,16 @@ jobs: cache-from: type=gha,scope=studio-${{ matrix.platform }} cache-to: type=gha,scope=studio-${{ matrix.platform }},mode=min outputs: type=image,name=${{ env.REGISTRY }}/${{ env.IMAGE_NAME }},push-by-digest=true,name-canonical=true,push=true - # Both refs are the SAME resolved shas the base build baked (prepare - # job), so the Studio tree + its zoo overlay match the base venv even - # if the branch moved mid-run.

TileLang JIT and torch.utils.cpp_extension resolve nvcc through /usr/local/cuda, so on the 570-driver hosts this image supports they would emit cu13 cubins that need driver 580 and fail at load. Pin the alternative back to 12.8 right after the cu13 install; the cu13 tools stay reachable by absolute path, which is exactly how the entrypoint activates them, and manual mode prevents future apt flips. run.sh accepted the native --gpus device=0,1 form through an unquoted passthrough, but docker requires the comma-carrying value to be quoted (daemon rejects it with 'cannot set both Count and DeviceIDs'; reproduced against a live daemon, and the docker GPU docs call the quoting out explicitly). A native multi-device selector is now wrapped in the same embedded quotes the other comma paths already use; single-device and pre-quoted forms pass through unchanged. All eight selector forms verified through the case block. --- docker/Dockerfile | 8 ++++++++ docker/run.sh | 6 ++++-- 2 files changed, 12 insertions(+), 2 deletions(-) diff --git a/docker/Dockerfile b/docker/Dockerfile index 5bc6067154..72587c3354 100644 --- a/docker/Dockerfile +++ b/docker/Dockerfile @@ -589,6 +589,14 @@ RUN set -eux; \ apt-get install -y --no-install-recommends \ cuda-nvrtc-13-0 \ cuda-nvcc-13-0; \ + # cu13's config-common postinst flips the /usr/local/cuda alternative to + # cuda-13.0 (priority 130 beats 12.8's 128).

The shared default marker leaked one run's transformers pin into later or concurrent runs in the same container: a notebook pinned to 4.57.6 left the marker behind and the next unpinned run's kernel activated the stale sidecar. An empty marker reads as no pin, so pre-creating the file is safe. The vLLM startup wait in dataprep/synthetic.py capped every poll at a full second regardless of the remaining budget, so a fractional timeout could overshoot by up to a second. The final wait is now clamped to the remaining time; verified empirically (timeout=1.1 elapses 1.10s). /workspace and the default HF/Triton cache dirs were root-owned, so docker run --user without a bind mount could not sync notebooks or populate caches. They are now world-writable (a+rwX), matching the documented non-root use the /opt prebuilt placement already supports. --- docker/Dockerfile | 5 ++++- docker/unsloth_run.py | 13 +++++++++++-- unsloth/dataprep/synthetic.py | 10 ++++++++-- 3 files changed, 23 insertions(+), 5 deletions(-) diff --git a/docker/Dockerfile b/docker/Dockerfile index 5f60589c91..9e7bf98892 100644 --- a/docker/Dockerfile +++ b/docker/Dockerfile @@ -516,7 +516,10 @@ RUN /opt/unsloth-venv/bin/python /tmp/fetch_llama_prebuilt.py \ ENV UNSLOTH_LLAMA_CPP_PATH=/opt/unsloth/llama.cpp WORKDIR /workspace -RUN mkdir -p ${HF_HOME} ${TRITON_CACHE_DIR} +# World-writable so `docker run --user ` (documented non-root use) can +# create notebooks and populate the default caches without a bind mount. +RUN mkdir -p ${HF_HOME} ${TRITON_CACHE_DIR} \ + && chmod -R a+rwX /workspace # --------------------------------------------------------------------------- # Per-notebook transformers version activation -- run unslothai/notebooks diff --git a/docker/unsloth_run.py b/docker/unsloth_run.py index 95d1f39c90..b4591c7151 100644 --- a/docker/unsloth_run.py +++ b/docker/unsloth_run.py @@ -103,10 +103,19 @@ def main(): env = dict(os.environ) env["UNSLOTH_NB_SHIM"] = "1" # enable safe-install for the notebook's cells + # Per-run marker unless the caller pinned one: the shared default would leak + # this run's transformers pin into later or concurrent runs in the same + # container (their kernels would activate a stale sidecar).

The CUDA runtime base image only carries libcudart, and the only libcublas in the image is torch's wheel copy under site-packages/nvidia/cublas/lib, which was not on the loader path. So the CUDA backend failed to load, and llama.cpp said nothing about it: `--list-devices` printed an empty list and every GGUF request ran on the CPU. Measured in the built image on a B200 with gemma-4-E2B-it UD-Q4_K_XL: 1.6 tok/s from llama-cli and 4.2 tok/s from llama-server. With the fix, the same image and model report `CUDA0: NVIDIA B200` and run at 229 tok/s and 193 tok/s. Studio's GGUF chat and the GGUF export path go through the same bundle, so both were affected. The venv loader config already existed for torchcodec, so cublas/lib joins it there rather than on LD_LIBRARY_PATH: ld.so.conf.d is consulted after DT_RUNPATH, which keeps llama.cpp resolving its own $ORIGIN libs first. cu13/lib comes along for the arm64 bundle's layout. A silent 140x slowdown deserves a build-time gate, so the layer after the fetch runs ldd over libggml-cuda.so, installs the cublas major the bundle actually asks for when it is missing, and fails the build on anything still unresolved. The amd64 bundle wants libcublas.so.12 and torch already provides it; the arm64 bundle is CUDA 13, and deriving the major from ldd keeps that leg honest without hardcoding either. libcuda.so.1 is exempt: nvidia-container-toolkit injects the driver stub at `docker run --gpus`, so it is never resolvable at build time. ldd needs no GPU, so the build stays host-independent. tests/python/test_docker_llama_cuda_backend.py pins the loader entry, the guard, the driver-stub exemption and the ordering. --- docker/Dockerfile | 39 +++++++- .../python/test_docker_llama_cuda_backend.py | 89 +++++++++++++++++++ 2 files changed, 127 insertions(+), 1 deletion(-) create mode 100644 tests/python/test_docker_llama_cuda_backend.py diff --git a/docker/Dockerfile b/docker/Dockerfile index 35083878c1..dc29131350 100644 --- a/docker/Dockerfile +++ b/docker/Dockerfile @@ -432,10 +432,13 @@ RUN set -eux; \ # Register the venv's torch + NVIDIA lib dirs with the loader so torchcodec can # dlopen them. ld.so.conf.d, NOT LD_LIBRARY_PATH: the cache is consulted after # DT_RUNPATH, so llama.cpp keeps resolving its own $ORIGIN libs first. +# cublas/lib and cu13/lib are here for llama.cpp's libggml-cuda.so, which links +# against libcublas but does not ship it (see the guard after the fetch below).

The cost of dropping it is not a no-op. Measured on a LoRA Qwen2-VL under transformers 5.14.1, with the model's forward hooked so the validator still sees the real signature: asking for logits_to_keep=0 (the whole sequence) reached forward as 1 and returned logits of shape (1, 1, 151936); with the value preserved it reached forward as 0 and returned (1, 88, 151936). Deleting the pops outright would be wrong in the other direction. An explicit num_logits_to_keep raises from _validate_model_kwargs on plain, PEFT, text and vision models alike, because v5 renamed it away, and logits_to_keep raises on the 12 of 79 image-text-to-text architectures whose top-level forward does not take it. So each key is now stripped only when _unsloth_generate_accepts_kwarg says this model would reject it, which is the same predicate the validator uses. Under PEFT, self inside the wrapper is the object the validator later runs against, so the check has no false negatives there. Also softened the comment above the branch. Unsloth 2026.7.5 does pre-inject on a LoRA Qwen2-VL under 5.14.1 and generation succeeds, so "pre-injecting makes the strict validator raise on PEFT models" overstates it. Skipping the injection on v5 is still right: it is redundant, and the arch walk can select a key the top-level model rejects. tests/test_generate_kwarg_gate.py gains four cases covering a preserved supported value, a stripped unsupported one, untouched neighbours, and the absence of the unconditional pop. --- tests/test_generate_kwarg_gate.py | 44 +++++++++++++++++++++++++++++++ unsloth/models/vision.py | 18 ++++++++++--- 2 files changed, 58 insertions(+), 4 deletions(-) diff --git a/tests/test_generate_kwarg_gate.py b/tests/test_generate_kwarg_gate.py index 6d1379d3a9..242fcebfbf 100644 --- a/tests/test_generate_kwarg_gate.py +++ b/tests/test_generate_kwarg_gate.py @@ -130,6 +130,50 @@ def test_generate_kwarg_gate(): assert got is expected, f"{name}: got {got}, expected {expected}" +# --- v5 logits-to-keep filtering ------------------------------------------ +# transformers >= 5 injects logits_to_keep=1 in generate() itself, but the +# injection is guarded by `"logits_to_keep" not in model_kwargs`, so it is a +# DEFAULT.

Every unsloth_cli subcommand that touches the studio backend died on import. `unsloth list-checkpoints` on the published image: ModuleNotFoundError: No module named 'structlog' and the same for train / export / chat, since all four import studio.backend.core.*. structlog is a studio backend requirement, not an unsloth[huggingface] one, so nothing in the base install pulled it in. Added it to the base venv, and added a build-time `from studio.backend.core.export import ExportBackend` so a future missing dependency in that closure fails the build instead of the user's first CLI invocation. That guard has to live in the LAST builder verification block: the closure also needs starlette, which only arrives with vLLM two stages later. 2. flashinfer-jit-cache was pinned to a literal 0.6.6 while vLLM 0.26.0 resolves flashinfer-python 0.6.14. flashinfer raises at import when the two disagree, and that exception is thrown inside the vLLM EngineCore, so Unsloth's GRPO fast_inference path fails at engine start with no earlier warning. A literal pin drifts again on the next vLLM bump, so the version is now read back from the resolved flashinfer-python, and the build proves `import flashinfer` works. Verified on the rebuilt image: flashinfer-python 0.6.14 with flashinfer-jit-cache 0.6.14+cu128, structlog 26.1.0, the export backend importable, and `unsloth list-checkpoints` exiting 0. tests/python/test_docker_llama_cuda_backend.py gains two static cases pinning both: the jit-cache version must be derived rather than literal and the build must import flashinfer, and the base venv must ask for structlog with the CLI reachability guard present. --- docker/Dockerfile | 29 +++++++++++++++++-- .../python/test_docker_llama_cuda_backend.py | 28 ++++++++++++++++++ 2 files changed, 54 insertions(+), 3 deletions(-) diff --git a/docker/Dockerfile b/docker/Dockerfile index dc29131350..9348c89d1a 100644 --- a/docker/Dockerfile +++ b/docker/Dockerfile @@ -121,7 +121,11 @@ RUN set -eux \ "bitsandbytes>=0.49.2,!=0.46.0,!=0.48.0" \ "unsloth_zoo @ git+https://github.com/unslothai/unsloth-zoo@${UNSLOTH_ZOO_REF}" \ "unsloth[${UNSLOTH_EXTRA}] @ git+https://github.com/unslothai/unsloth@${UNSLOTH_REF}" \ - "timm>=1.0.11" "addict" + `# structlog is a studio backend dep, not an unsloth[huggingface] dep,` \ + `# but unsloth_cli's train / export / chat / list-checkpoints all import` \ + `# studio.backend.core.*, so without it every one of them dies on` \ + `# ModuleNotFoundError.

Selection was a pure ceiling (smallest baked version >= the request) and ignored that vLLM is version-locked to transformers, so two of the four baked sidecars could not be imported by the baked vLLM 0.26.0 at all: 4.57.6 ImportError: Support for Transformers v4 is deprecated and was removed in vLLM v0.24.0 5.3.0 ImportError: cannot import name 'ALLOWED_LAYER_TYPES' from transformers.configuration_utils Those two are exactly the ones the common pins select. 241 notebooks pin 4.48/4.52.3/4.55.4/4.56.1/4.56.2/4.57.x and land on the 4.57.6 sidecar, 13 pin 5.2.0/5.3.0 and land on the 5.3.0 sidecar. All 254 died at `from unsloth import FastModel`, before the first model cell.

Which versions clear the floor is measured, not hardcoded: the build imports vllm.transformers_utils.config under every candidate sidecar, deletes the ones that raise, and records the lowest survivor. That is the vLLM module which reads the transformers API, it reproduces both failures, and it imports without a GPU, which matters because the build host has none. A request below the floor is clamped up to the lowest eligible sidecar, the closest version to the notebook's pin this image can actually run; a request above every sidecar still falls through to the baked transformers. Measured on the rebuilt image: sidecars 5.5.0 and 5.10.2 survive, floor 5.5.0, tf-sidecars drops from 250M to 123M, and all 13 distinct transformers pins found across the 433 shipped notebooks now reach `from unsloth import FastModel`.

Across the 433 shipped notebooks that left the training half wide open: trl 382 pin an older release, 378 of them ending the install cell with `pip install --no-deps trl==0.22.2`, against a baked trl 0.24.0 torchao 273 reinstall it and 2 pin 0.15.0, replacing 0.17.0+cu128 torchcodec 92 reinstall it and 26 pin 0.5 or 0.7.0, replacing the 0.11.0+cu128 wheel the Dockerfile pairs with torch 2.11 datasets 254 reinstall it, observed falling from 4.3.0 to 3.0.0 peft 225 reinstall it, observed falling from 0.19.1 to 0.14.0 accelerate 225 reinstall it hf hub 240 reinstall it and tokenizers 64, both version-locked to transformers and shipped in matched copies inside every sidecar So every notebook run mutated the stack the image was validated with, while the shim printed that it was keeping the baked versions. The membership criterion is "replacing this invalidates the tested stack or breaks unsloth", not "a notebook mentions it": snac, causal-conv1d, mamba-ssm, omegaconf, protobuf, sentencepiece and the rest still install normally. Verified in the rebuilt image by running the Gemma3 (270M) install cell verbatim: trl 0.24.0, peft 0.19.1, datasets 4.3.0, accelerate 1.14.0, torchao 0.17.0+cu128, transformers 5.14.1 and huggingface_hub 1.24.0 are all unchanged afterwards, the requested transformers pin is still recorded for the sidecar, and a package the image does not bake still installs. The existing shim tests used peft as their "unprotected package" sentinel, so they move to snac. --- docker/unsloth_pip_shim.py | 42 +++- .../test_docker_pip_shim_training_stack.py | 196 ++++++++++++++++++ tests/python/test_unsloth_pip_shim.py | 108 +++++----- 3 files changed, 289 insertions(+), 57 deletions(-) create mode 100644 tests/python/test_docker_pip_shim_training_stack.py diff --git a/docker/unsloth_pip_shim.py b/docker/unsloth_pip_shim.py index 5d793303c7..35bc2ffe29 100644 --- a/docker/unsloth_pip_shim.py +++ b/docker/unsloth_pip_shim.py @@ -11,9 +11,15 @@ carefully-resolved cu128 torch/vLLM/transformers stack: * `transformers==X` -> NOT installed into the base venv.

The sync backgrounds a GitHub refresh child and the parent exits immediately, firing its `trap finalize EXIT` (Colab intro strip plus categorized view rebuild) while the child is concurrently cp -a'ing refreshed notebooks into the same tree and rewriting the same state file. Six identical fresh-container boots reported cleaned 337/311/316/277/297/360 notebooks, and one of them published a categorized view holding 176 of 359 notebooks because both processes tore down and rebuilt the symlink farm at once. The lost writes are permanent: 222 to 309 recorded hashes no longer matched the file on disk, so those notebooks were treated as user-edited and skipped by every later strip, which is where 10 of the 23 notebooks still carrying the Colab intro came from. Keep the refresh detached, which is the whole point of it, and fix the ordering instead. One exclusive flock covers a whole invocation so the child cannot start until the parent has exited, the parent runs the finalize explicitly before it forks so the order holds even where flock is missing, the finalize is run-once, and the child re-arms it only when the refresh actually copied something. The strip itself only inspected cells[0], which missed 23 of the 433 shipped notebooks: 21 put the Colab badge in cells[0] and the sentence in cells[1] (Advanced_Llama3_2_(3B)_GRPO_LoRA, Falcon_H1-Alpaca, gpt-oss-(20B)-GRPO and friends), and 2 (NeMo-Gym-*) wrap the sentence in a single-line HTML comment. Scan the leading markdown block instead, stopping at the first code cell so it can never reach prose between code cells, and match the closed single-line comment form. The strip stays idempotent and leaves the content signature of all 433 notebooks unchanged, so the boot refresh does not re-copy and re-strip them forever. Measured on the rebuilt image: ten consecutive fresh-container boots all report cleaned 536 notebook(s) and view 359 notebooks in 26 folders, 0 of 433 notebooks retain the Colab intro (was 23), 0 recorded hashes mismatch (was 222 to 309), and a second boot on the same volume is a no-op. --- docker/unsloth_nb_strip_colab.py | 55 +++++-- docker/unsloth_sync_notebooks.sh | 75 ++++++++- .../test_docker_nb_strip_colab_scope.py | 152 ++++++++++++++++++ tests/python/test_docker_nb_sync_race.py | 136 ++++++++++++++++ 4 files changed, 407 insertions(+), 11 deletions(-) create mode 100644 tests/python/test_docker_nb_strip_colab_scope.py create mode 100644 tests/python/test_docker_nb_sync_race.py diff --git a/docker/unsloth_nb_strip_colab.py b/docker/unsloth_nb_strip_colab.py index 95b89a72f0..4ffa67a0a1 100644 --- a/docker/unsloth_nb_strip_colab.py +++ b/docker/unsloth_nb_strip_colab.py @@ -33,11 +33,31 @@ _INTRO_PREFIX = "to run this, press" _WIDGET_VIEW_MIME = "application/vnd.jupyter.widget-view+json" +def _is_intro_line(line): + """True for the Colab run announcement in either shipped spelling. + + Most notebooks open the line with the sentence itself, but two (NeMo-Gym-*) + ship it inside a single-line HTML comment: + + + + Only a comment that OPENS AND CLOSES on the same line is matched, so + dropping it can never leave a dangling `"): + return stripped[4:-3].strip().lower().startswith(_INTRO_PREFIX) + return False + + def _strip_lines(lines): """Drop the intro line (and an immediately-following blank).

Verified: the shim suite is 87 passed / 2 skipped in both a bare venv and a full one; the shell suite still reports 14 passed on Linux and skips with exit 0 under a simulated no-symlink filesystem. --- tests/python/test_unsloth_pip_shim.py | 41 ++++++++++++++++++++++++-- tests/sh/test_select_cuda_jit_tools.sh | 18 +++++++++++ 2 files changed, 57 insertions(+), 2 deletions(-) diff --git a/tests/python/test_unsloth_pip_shim.py b/tests/python/test_unsloth_pip_shim.py index 0573efcf31..dd993898f3 100644 --- a/tests/python/test_unsloth_pip_shim.py +++ b/tests/python/test_unsloth_pip_shim.py @@ -511,9 +511,36 @@ def _raw_execd(shim, tool, args): return exc.argv[exc.argv.index("install") + 1 :] -def test_forwarded_install_carries_protected_constraints(shim): +class _FakeDist: + """Minimal stand-in for an importlib.metadata Distribution.""" + + def __init__(self, name, version): + self.metadata = {"Name": name} + self.version = version + + +def _fake_distributions(monkeypatch, *pairs): + """Pin what _protected_constraints_file sees as INSTALLED. + + It reads the ambient environment via importlib.metadata.distributions, so + without this the outcome depends on whatever happens to be in the venv: + with no protected package installed it correctly returns None (see its + docstring) and no --constraint pair is appended.

Every hardware branch assigns its own torch/torchvision/torchaudio triple, so #7354 adding gfx906 pushed three of those counts up by one and Backend CI has been red on main since: FAIL: default TORCH_CONSTRAINT assignment exists (expected '1', got '2') FAIL: hardcoded torch>=2.4 appears exactly once (expected '1', got '2') FAIL: torchvision bounded (<0.26) at default + custom-leaf (expected '2', got '3') FAIL: torchaudio bounded (<2.11) at default + custom-leaf (expected '2', got '3') install.sh is correct; the numbers were the stale part. Assert the invariants instead, so the next hardware branch is not a test edit: - the default assignment is the top-level one, so anchor the grep at column 0 rather than counting every occurrence. An indented branch pin no longer satisfies it, which the old count did not distinguish either. - what "appears exactly once" really guarded is that no pip install line spells a pin out instead of using "$TORCH_CONSTRAINT", so check that directly. - companions must be bounded everywhere, so compare bounded assignments against total assignments rather than pinning a count of 2. That is strictly stronger: it now covers all 7, not the 2 the old numbers happened to name. 45 pass, 0 fail.

On Windows AMD, auto-fallback to Vulkan when no detected gfx arch is in the upstream win-hip-radeon GPU_TARGETS set (e.g. gfx803 / RX 480). Mixed setups where at least one card is HIP-supported still default to HIP unless opted in. * [pre-commit.ci] auto fixes from pre-commit.com hooks for more information, see https://pre-commit.ci * fix(install): address Codex P2s on Vulkan gfx routing (#7357) Honor ROCm family tokens (gfx110X), include fork-supported gfx1103, require a known active gfx before auto-Vulkan, and base the HIP floor check on the visible-device target instead of every physical GPU in hipinfo. * Address Codex review: env namespace, physical-NVIDIA guard, test kwarg - llama_backend_from_env: stop reading UNSLOTH_LLAMA_CPP_BACKEND. That is a separate pre-existing setup variable meaning auto/cpu; setup.sh/setup.ps1 warn and ignore other values, so reading it here forced Vulkan behind that warning. Vulkan opt-in stays on UNSLOTH_LLAMA_BACKEND / UNSLOTH_FORCE_VULKAN. - _should_auto_vulkan_for_amd_windows: gate on not has_physical_nvidia (not merely has_usable_nvidia). A CUDA-masked NVIDIA card keeps has_physical_nvidia while has_usable_nvidia goes False; Vulkan ignores CUDA_VISIBLE_DEVICES and could enumerate the reserved card. Mirrors the Intel auto path. Explicit opt-in still overrides. - test fakes: validate_prebuilt_attempts/validate_prebuilt_choice gained a llama_backend kwarg; the four fake signatures in the fallback tests now accept it, clearing the TypeError that reddened Backend CI / Repo tests (CPU). Tests: UNSLOTH_LLAMA_CPP_BACKEND=vulkan no longer triggers Vulkan; hidden physical NVIDIA suppresses AMD auto-Vulkan while explicit opt-in overrides. * Keep gfx1034 on the ROCm path (fork gfx103X bundle covers it) The WINDOWS_HIP_PREBUILT_GFX_TARGETS allow-list omitted gfx1034, so _route_to_vulkan_prebuilt downgraded RX 6500/6400-class hosts to the upstream Vulkan prebuilt before published_rocm_choice_for_host could match the fork windows-rocm gfx103X bundle (whose members include gfx1034). Add gfx1034 to the allow-list and a regression test asserting it stays on the fork ROCm asset. * Fix auto-Vulkan stealing fork windows-rocm gfx908/gfx90a hosts for PR #7373 * [pre-commit.ci] auto fixes from pre-commit.com hooks for more information, see https://pre-commit.ci * Fix Vulkan marker claiming a backend that was never installed for PR #7373 * [pre-commit.ci] auto fixes from pre-commit.com hooks for more information, see https://pre-commit.ci * Tighten the Vulkan backend routing comments for PR #7373 * Keep the visible-device-aware gfx when setup forwards --rocm-gfx setup.ps1 resolves the gfx arch from its own probe, and that pick is not fully visible-device aware: neither the hipinfo nor the amd-smi branch reads CUDA_VISIBLE_DEVICES, and the amd-smi branch matches a bare integer only, so a comma-separated HIP/ROCR mask such as 1,0 also falls back to GPU 0. The resulting arch was then forwarded through --rocm-gfx and replaced the arch detect_host() had already resolved for the runtime-visible GPU. On a mixed-AMD Windows host that flipped the auto-Vulkan decision: with GPU 0 gfx1100 and a masked-in gfx1010, the forward reinstated gfx1100, _should_auto_vulkan_for_amd_windows() saw a HIP-supported arch and the HIP bundle was installed for a GPU that cannot run it. Fold the forward in as a fill rather than a replacement: it still supplies the arch on amd-smi-only, driver-only and name-inferred hosts where the probe reports none, which is what --rocm-gfx exists for, but no longer overwrites a successfully detected active arch. An explicit UNSLOTH_ROCM_GFX_ARCH stays authoritative, since it is the documented manual override for hosts whose arch the probes get wrong. * [pre-commit.ci] auto fixes from pre-commit.com hooks for more information, see https://pre-commit.ci * Scope the Windows AMD Vulkan fallback per device and per repo Three follow-ups on the auto-Vulkan routing for #7357. Keep an explicit --rocm-gfx authoritative. The previous round stopped a forwarded gfx from replacing an arch detect_host() had already resolved, but --rocm-gfx is also the documented operator override for hosts whose probe is wrong or stale, and both arrive as the same argv. Narrow the advisory case to the two shapes setup can actually be describing: an arch the probe saw on this host (setup picked a different physical GPU of the same box), or a family label such as gfx110X, which is a bundle name the update path derives from the marker asset rather than a real GPU arch. Any other value is an override for an arch no probe reported and stays authoritative. Keeping family labels advisory also preserves the rule that an in-generation-but-unbuilt arch (gfx1033) is never upgraded into the gfx103X bundle. Do not auto-route to Vulkan from a HIP-only device mask. HIP_VISIBLE_DEVICES, ROCR_VISIBLE_DEVICES and CUDA_VISIBLE_DEVICES select the active arch, but the Vulkan runtime honours none of them: it enumerates through GGML_VK_VISIBLE_DEVICES and Vulkan ordinals in LlamaCppBackend._get_gpu_free_memory_vulkan. Masking down to a below-floor card therefore used to install a backend that could still enumerate the HIP-capable card the user deliberately hid, possibly one reserved for another workload. Require every physical AMD gfx to be below the floor, matching the has_physical_nvidia gate right above it. So the per-GPU list survives to that check, a forward that agrees with the probe no longer collapses rocm_gfx_targets to a single entry. Make the HIP support predicate repository-specific. The floor constant is a union of ggml-org's windows-hip gpu_targets and the fork's windows-rocm bundles, so it only answers "is this arch served" for the fork. With --published-repo ggml-org/llama.cpp, direct_upstream_release_plan() offers win-hip-radeon then CPU and never Vulkan, so the four fork-only archs (gfx908, gfx90a, gfx1034, gfx1103) were declared supported and fell through to CPU instead of the Vulkan bundle that would actually run. Add UPSTREAM_WINDOWS_HIP_GFX_TARGETS and select the set from the planned repo. * Keep probe-confirmed AMD GPUs in the physical list when a gfx is forwarded rocm_gfx_targets is the physical inventory _should_auto_vulkan_for_amd_windows() reads, so a forwarded --rocm-gfx that the probe never reported was deleting cards the probe had confirmed. On a mixed Windows AMD box whose active device is masked down to a below-floor card, a stale UNSLOTH_ROCM_GFX_ARCH or a name-inferred arch for the other GPU collapsed the list to that one arch, the floor check concluded no AMD GPU on the host reaches the Windows HIP prebuilt, and the install auto-fell back to Vulkan, which honours no HIP mask and would enumerate the reserved HIP-capable card. Add the forwarded arch to the list instead of replacing it: it selects the HIP target, it does not redefine what hardware is present. An empty probe still yields a single-entry list, so the driver-only Windows AMD host the forward exists for keeps its automatic Vulkan fallback, and an explicit --llama-backend vulkan is unaffected. * Do not auto-fall back to Vulkan when a HIP device mask filtered the probe hipinfo is itself a HIP application, and AMD documents HIP_VISIBLE_DEVICES as "only devices whose index is present in the sequence are visible to HIP", with that spelling recommended on Windows. Under a mask the Windows probe therefore enumerates the visible devices, so rocm_gfx_targets is what survived the mask rather than the physical inventory the auto-Vulkan floor check assumes. A masked-out gfx1100 next to a visible gfx803 made the check conclude that no AMD GPU on the box reaches the Windows HIP prebuilt and route the install to Vulkan, which honours none of these masks and would enumerate the reserved card. Decline to guess when a mask is set: the physical inventory is unknowable from a masked probe, so keep the HIP / fork / source path. This only ever turns the automatic fallback off, never on. The driver-only single-GPU host the fallback exists for sets no mask, an all-hiding "" / -1 mask is still handled as no active target rather than a partial view, and an explicit --llama-backend vulkan or UNSLOTH_LLAMA_BACKEND=vulkan is unaffected. Reading the physical inventory through an unmasked re-probe would also correct _pick_rocm_gfx_target, which indexes the token list by the mask value and so already assumes an unmasked probe. That is pre-existing behaviour on main and is left alone here. * [pre-commit.ci] auto fixes from pre-commit.com hooks for more information, see https://pre-commit.ci * Treat an all-hiding HIP device mask as suppressing the Vulkan fallback too The mask guard exempted an empty or -1 value on the grounds that the probe reports no active target under it, but that only holds for the probe: a forwarded --rocm-gfx still reconstructs an active arch, and setup infers that arch from the display-adapter name, which no HIP mask touches. A user who hid every AMD GPU from HIP could therefore still be auto-routed to Vulkan, which honours none of these masks and would then use all of them. That is the strongest form of the hazard the guard exists for, not an exemption from it. Presence of any of the three variables is now the whole test, which also removes the value parsing. An explicit --llama-backend vulkan or UNSLOTH_LLAMA_BACKEND is still unaffected. * Grant the fork-only Windows HIP coverage to the fork, not to every mirror The floor set is a union of the fork's windows-rocm bundles and only the fork is planned from its manifest: resolve_simple_install_release_plans() compares == DEFAULT_PUBLISHED_REPO and sends every other --published-repo through direct_upstream_release_plan(), whose AMD branch offers win-hip-radeon then CPU and never Vulkan. Exempting only the exact ggml-org spelling therefore told a mirror carrying upstream-standard assets that fork-only archs such as gfx1034, gfx1103 and gfx908 were HIP-served, landing them on HIP or CPU instead of the Vulkan bundle that would actually run. Gate on the fork instead. Matching the dispatch exactly, spelling included, also fixes a differently cased repo: that really does take the upstream path, so it must be answered with upstream coverage rather than the fork superset. An empty repo still defaults to the fork, as the resolver does. * Derive the Windows HIP gfx floor guard from the published manifest The guard compared WINDOWS_HIP_PREBUILT_GFX_TARGETS against a second hardcoded tuple in the same test file, so a windows-rocm arch newly published by the fork passed both. Affected hosts would then be routed off the hash-approved fork ROCm bundle onto an unhashed upstream Vulkan build with nothing failing. Read the fork's llama-prebuilt-manifest.json through the installer's own resolver instead, and assert the floor, the family labels, and the routing tuple all still cover what it publishes. The manifest ships only as a release asset, so an unreachable release skips with an explicit reason rather than flaking. Both literals match the manifest as published today. * [pre-commit.ci] auto fixes from pre-commit.com hooks for more information, see https://pre-commit.ci * Compress the Vulkan backend routing comments and docstrings for PR #7373 * Correct the family-label rationale in the Windows HIP coverage check The comment justified serving gfx103X / gfx110X against any repository by claiming upstream's windows-hip targets build every member of those families. The fork manifest maps gfx103X to gfx1030..1032 plus gfx1034 and gfx110X to gfx1100..1102 plus gfx1103, and UPSTREAM_WINDOWS_HIP_GFX_TARGETS carries neither gfx1034 nor gfx1103, so the stated reason is wrong even though the answer is right. State the real reason instead. A family label is a bundle name, not an arch, so the concrete GPU is unknown at this point; answering unsupported to cover the two uncovered members would move gfx1030..1032 and gfx1100..1102 off a working HIP build onto Vulkan for a card the label cannot identify. Those two archs still reach Vulkan through the concrete-arch branch below, which does answer per repository. Comment only. No behaviour change: the 5850-combination override sweep still reports 0 rocm_gfx_target changes, 0 auto_vulkan False to True flips and 680 True to False flips all backed by a probe-confirmed HIP GPU, and both the feature and override profile matrices are byte-identical. * Pin that a deliberate CPU install outranks Vulkan for PR #7373 UNSLOTH_LLAMA_CPP_BACKEND (setup.sh / setup.ps1, "auto" or "cpu") and UNSLOTH_LLAMA_BACKEND (this module, a backend name) are separate variables at separate layers, and both accept "cpu". setup translates its own =cpu into --force-cpu, which is what pins the CPU-only bundle on a GPU host and keeps Intel iGPU Vulkan crashes away (#7213), so no trigger this PR adds may outrank it. _route_to_vulkan_prebuilt already gets this right, since force_cpu short-circuits ahead of the forced, auto-Intel and auto-no-HIP triggers. Cover it so it stays that way: the matrix runs [Linux, Windows, macOS] x [NVIDIA, AMD, Intel, CPU only] x [unset, vulkan, hip, rocm, cpu] with the legacy UNSLOTH_FORCE_VULKAN set as well, and asserts the published bundle survives every one. WSL presents as Linux to this resolver, so it rides the Linux row. Also assert the guard is not vacuous: the same host still takes Vulkan once the CPU pin is gone, so the matrix cannot pass on a resolver that had simply stopped routing to Vulkan. * [pre-commit.ci] auto fixes from pre-commit.com hooks for more information, see https://pre-commit.ci --------- Co-authored-by: pre-commit-ci[bot] <66853113+pre-commit-ci[bot]@users.noreply.github.com> Co-authored-by: LeoBorcherding Co-authored-by: Daniel Han --- .../tests/test_install_resolve_prebuilt.py | 831 +++++++++++++++++- studio/backend/tests/test_llama_cpp_update.py | 4 + studio/backend/utils/llama_cpp_update.py | 18 +- studio/install_llama_prebuilt.py | 446 ++++++++-- .../test_install_llama_prebuilt_logic.py | 4 + tests/studio/install/test_rocm_support.py | 88 +- 6 files changed, 1308 insertions(+), 83 deletions(-) diff --git a/studio/backend/tests/test_install_resolve_prebuilt.py b/studio/backend/tests/test_install_resolve_prebuilt.py index 02ccc68b11..957ef7e574 100644 --- a/studio/backend/tests/test_install_resolve_prebuilt.py +++ b/studio/backend/tests/test_install_resolve_prebuilt.py @@ -6,7 +6,9 @@ by default; --published-repo overrides).

Publish through a same-dir dot-prefixed temp plus an atomic rename, and re-read the hash once the staging copy is complete (the earlier check sits before middle_unchanged, a python subprocess, so the window was most of the loop). A single-file bind mount cannot be renamed over, so that path falls back to the previous copy. Notebook sync, first boot. A pre-existing file whose bytes already match the baked template fell through to cp -a, which is --preserve=all: as root that stamps root:root, the baked mode and the build mtime onto a bind-mounted host file and locks its owner out of editing it. Record it as managed instead. The hash is identical, so the state file is byte-for-byte what the copy wrote. unsloth-studio-update. The post-update import check only warned, then the default restart replaced a process that was serving fine with one known not to import. supervisord retries startretries times, lands in FATAL and never leaves it on its own, so the container serves nothing until someone execs in. Keep the running service and exit non-zero with the remedy. unsloth-llama-update --check. resolve_latest swallows every failure into an empty string, which fell into the "up to date" branch and exited 0, so the command reported a state it could not observe. Report UNKNOWN and fail. unsloth-llama-update rollback. The in-place restore iterates the backup's entries, so a file the new release introduced survives it and the restored tree is mixed-version; ggml dlopens every libggml-*.so next to the binaries. Clear the install dir before restoring, gated on the drain having completed, because before that an entry there can still be the only copy of an old file. docker-publish ref freeze. git ls-remote exits 0 whether or not a ref matched, so a non-zero exit means the remote was never reached. That exit was lost twice over: first element of a pipeline, and a run step with no explicit shell runs under bash -e without pipefail. The step exited 0 and published ref=main, which the amd64, arm64 and Studio builds each resolve again, so one multi-arch tag could carry different revisions. Fail the prepare job instead, keeping the passthrough for the reachable-but-no-match case it was written for. Jupyter output select. lastPointerOutput was only replaced by another pointer-down, but J/K/arrow cell navigation fires none, so Ctrl/Cmd+A on a later cell selected the previously clicked output and suppressed notebook:select-all; after a re-run the node is detached and the chord did nothing at all. Revalidate the remembered output (still in the document, still in the active cell) before using it as the fallback. Tests: four static guards in test_docker_nb_sync_race.py, a new behavioural test_docker_update_helpers.py driving both helpers with stub pip, supervisorctl and mv, a new test_docker_publish_ref_freeze.py that executes each resolver step under bash -e with a failing ls-remote, and a source check in validate_studio_features.py. Each fails against the code before this change; the interrupted-drain case also fails against the unconditional form of the rollback fix. --- .github/workflows/docker-publish.yml | 29 +- .../unsloth_labext/src/outputSelect.ts | 16 +- docker/unsloth_llama_update.sh | 27 +- docker/unsloth_studio_update.sh | 10 +- docker/unsloth_sync_notebooks.sh | 42 ++- tests/python/test_docker_nb_sync_race.py | 56 ++++ .../python/test_docker_publish_ref_freeze.py | 132 +++++++++ tests/python/test_docker_update_helpers.py | 250 ++++++++++++++++++ tests/validate_studio_features.py | 9 + 9 files changed, 558 insertions(+), 13 deletions(-) create mode 100644 tests/python/test_docker_publish_ref_freeze.py create mode 100644 tests/python/test_docker_update_helpers.py diff --git a/.github/workflows/docker-publish.yml b/.github/workflows/docker-publish.yml index d6f9a1d905..0382f3dc51 100644 --- a/.github/workflows/docker-publish.yml +++ b/.github/workflows/docker-publish.yml @@ -105,7 +105,17 @@ jobs: if printf '%s' "$REF" | grep -Eq '^[0-9a-f]{40}$'; then SHA="$REF" else - SHA="$(git ls-remote https://github.com/unslothai/unsloth "$REF" | awk 'NR==1{print $1}')" + # ls-remote exits 0 whether or not a ref matched, so a non-zero exit + # means we never reached the remote.

The runner's default `bash -e` shell takes sed's exit status, so an unreachable github.com left TAG empty and the step published the mutable `latest`. Both arch legs re-resolve that through fetch_llama_prebuilt.py and Dockerfile.studio resolves it a third time, so a release cut mid-run can put different llama.cpp bundles under one manifest. Capture the redirect first and fail the job when it is missing or does not land on a release tag, matching the three ref resolvers below it. unsloth_nb_strip_colab.py: strip_notebook read, parsed and then unconditionally os.replace'd. The refresh child re-arms finalize after the entrypoint has execed the container command, so JupyterLab is already serving the tree and a save landing in that window was destroyed, after which migrate recorded the cleaned hash and marked the notebook pristine forever. Re-read the hash once the staged copy is complete and drop it when the file moved, the same rule the refresh publish in unsloth_sync_notebooks.sh already follows. unsloth_nb_view.py: ownership for the view teardown accepted any symlink target under DEST, but every link the tool creates points at DEST/nb. A shortcut the user made in the landing dir to their own file elsewhere in the checkout was therefore classified as ours and deleted on the next boot. Key ownership on DEST/nb instead. cellNav.ts: the edit-mode boundary test compared the cursor line against editor.lineCount, both logical, while JupyterLab wraps markdown and raw editors by default (StaticNotebook.defaultEditorConfig). A one-line markdown header renders as several visual rows, so every arrow left the cell and the wrapped rows could not be reached. Ask CodeMirror whether it can still move one visual line (EditorView.moveVertically, compared by coordsAtPos top) and keep the logical test as the fallback for a non-CodeMirror editor.

Nothing recorded that, so three separate places all reported it healthy: - the desktop preflight probed only `unsloth -h` (typer + rich) and a hardcoded desktop-capabilities dict, neither of which touches studio.backend, so it returned ManagedReady and spawned a backend that died on `import structlog`; - setup.sh's fast path compared the installed unsloth version against PyPI, which matches on a half-built venv because unsloth is installed early, so `unsloth studio update` printed "up to date" and repaired nothing; - start_managed_repair calls that update and then re-checks with the same blind probes, so Repair reported success without fixing anything. install_python_stack.py now clears a completion manifest before the dependency pass and writes it only after the final step. `unsloth studio verify-install` and desktop-capabilities' new studio_install_ok field read it, the preflight turns a false answer into ManagedStale so auto-repair runs, and setup.sh / setup.ps1 gain an escape hatch next to the existing anyio one. Separately, the wheel ships studio/ and studio.backend* but declared none of their dependencies, so `unsloth train`, `export`, `chat`, `inference` and `studio` all ended in a rich traceback after a plain pip install. structlog is the only hard module-level import that chain reaches once starlette's annotation-only import moves under TYPE_CHECKING, so it becomes a core dependency and the rest of the server stack becomes a [studio] extra mirroring studio.txt. The CLI import sites now report missing dependencies as a sentence with two remedies. Fixes #4701, #5260, #7147 * [pre-commit.ci] auto fixes from pre-commit.com hooks for more information, see https://pre-commit.ci * Match the trimmed comments merged on the pip branch * Put the install manifest in the preflight fingerprint for PR #7492 The capability cache keyed the venv on pyvenv.cfg, uv.lock, requirements.txt, the interpreter and site-packages/unsloth_cli/commands/studio.py, none of which a repair touches when it only reinstalls studio.txt. So an entry cached while the install was healthy stayed valid after the manifest was dropped, and the probe returned Ready on exactly the half-built venv this is meant to catch. * Address the review findings on PR #7492 Fail the install when the completion manifest cannot be written, instead of exiting 0 without the record every later check requires, which is a repair loop by construction. Compare the version of the package the manifest names, so `studio update --package X` does not read as a permanent version change. Read the manifest from the venv that owns it when the CLI runs outside the managed venv, and drop the dependency verdict in that case: the walk ran against the wrong interpreter and says nothing about that venv. Name the import that actually failed. `unsloth train` reaches torch through the same guard, and the studio extra does not carry it, so recommending that extra alone left the command failing in the same place. * Declare click, which typer stopped providing, for PR #7492 unsloth_cli/commands/start.py imports click at module scope and unsloth_cli/__init__.py imports that module, so every unsloth command needs it. typer carried click through 0.19 and dropped it in 0.27, and the declared floor is typer>=0.12.0, so a fresh resolve gets no click. On the published wheel it still arrives because huggingface_hub requires click<9,>=8.4.2, which is luck rather than a declaration. A wheel built from this branch's dependency list has neither, and every command dies at import. Verified: before, `unsloth --help` on a fresh venv raised ModuleNotFoundError for click; after, it exits 0. The drift test now covers it. * Keep a running backend from the previous app version manageable The manageability bump gated two unrelated things through one constant. For the managed CLI probe 2 is right: a CLI reporting 1 cannot answer studio_install_ok. For a RUNNING backend it is wrong, because a process already started cannot change what it reports, so bumping studio/backend/main.py in lockstep does not help one the previous app version spawned. That backend is proven ours by root id and ownership token, but lifecycle_control_block_reason returned Unmanageable, and that branch never calls adopt_verified_backend. has_owned_backend() stays false, so Repair falls into block_external_conflict, which finds the same process and refuses: the app could no longer stop a backend it owns the token for. The same regression in backend.rs turned a terminal-launched same-root server from AttachedReady into ExternalConflict. Split the constant: DESKTOP_BACKEND_MANAGEABILITY_VERSION = 1 for the two live-backend probes, DESKTOP_MANAGEABILITY_VERSION = 2 for the CLI probe. Every real gate (protocol, auth, ownership, desktop-login, MIN_DESKTOP_BACKEND_VERSION) is untouched, so an old backend still reaches OwnedStale, adopt, stop, repair. Also stop the installer when the stale manifest cannot be removed. Windows raises on a read-only or locked file, and the pass would then run behind a marker that still names this version and these digests, so a run killed part-way would verify as complete. * Answer for the managed venv, not the one the CLI happens to run in The guard matched ModuleNotFoundError.name, an import name, against missing_requirements(), which returns distribution names. So a missing PyJWT printed 'pip install jwt', and jwt, docx and fitz are each a real but unrelated PyPI project (fitz is a neuroimaging workflow tool), so following the advice installed the wrong package and left the backend just as broken. Map the import to its distribution before deciding, and never offer the import itself. install_state() verified the caller's own prefix. The wheel ships studio/, so a CLI installed outside the managed venv always finds its own copy of the helper first, and a healthy managed install reported studio_install_incomplete with a missing list copied from the wrong venv. Selecting the root is not enough: _installed_version() reads the running interpreter and req_root defaults to the caller's studio.txt, so both checks still answered for the wrong venv. Hand verify_install() that venv's own metadata, enumerated through Distribution.discover(context = ...path), which does not fall back to sys.path. The candidate order is untouched, so shadowed-tree detection is unchanged. setup.ps1 replaces pip, torch and triton before install_python_stack.py runs, so the manifest it drops is not dropped before the first mutation. A run killed in between kept a marker that still verifies while torch was half-replaced; drop it at the top of the dependency pass instead. setup.sh is unaffected, the stack is the first thing its pass runs, and a test now pins both. pip uninstall rewrites nothing that was fingerprinted, and cache_matches re-reads the cached studio_install_ok rather than re-checking, so a venv that lost a studio.txt package kept being served the healthy verdict. Fold a sorted hash of the installed dist-info names into the marker hash. * [pre-commit.ci] auto fixes from pre-commit.com hooks for more information, see https://pre-commit.ci * A missing manifest helper is a torn install, not an old one studio/install_manifest.py ships in the same wheel as _studio_deps.py, so nothing legitimately has one without the other: a CLI predating both never reaches this code, and the desktop already calls such a CLI stale on desktop_manageability_version. Returning ok=true there reported a healthy install for a tree the package update had half replaced, and the preflight then launched a backend whose own run.py could be just as absent. Report it incomplete so repair runs. * Tighten comments across the install-detection changes * Validate Studio dependency readiness --------- Co-authored-by: pre-commit-ci[bot] <66853113+pre-commit-ci[bot]@users.noreply.github.com> Co-authored-by: Lee Jackson <130007945+Imagineer99@users.noreply.github.com> Co-authored-by: Wasim Yousef Said --- .github/workflows/studio-update-smoke.yml | 40 +++ .github/workflows/wheel-smoke.yml | 25 ++ pyproject.toml | 33 ++ studio/backend/loggers/handlers.py | 9 +- studio/backend/main.py | 7 +- studio/install_manifest.py | 305 ++++++++++++++++++ studio/install_python_stack.py | 32 ++ studio/setup.ps1 | 42 +++ studio/setup.sh | 15 + studio/src-tauri/src/desktop_backend_owner.rs | 62 +++- studio/src-tauri/src/preflight.rs | 52 ++- studio/src-tauri/src/preflight/backend.rs | 4 +- studio/src-tauri/src/preflight/managed.rs | 300 +++++++++++++++-- studio/src-tauri/src/preflight/version.rs | 10 +- tests/studio/install/test_install_manifest.py | 203 ++++++++++++ .../install/test_setup_fast_path_guard.py | 99 ++++++ tests/studio/install/test_studio_deps_cli.py | 273 ++++++++++++++++ .../test_studio_extra_matches_requirements.py | 85 +++++ unsloth_cli/_inference.py | 15 +- unsloth_cli/_studio_deps.py | 255 +++++++++++++++ unsloth_cli/commands/export.py | 8 +- unsloth_cli/commands/studio.py | 54 +++- unsloth_cli/commands/train.py | 10 +- 23 files changed, 1877 insertions(+), 61 deletions(-) create mode 100644 studio/install_manifest.py create mode 100644 tests/studio/install/test_install_manifest.py create mode 100644 tests/studio/install/test_setup_fast_path_guard.py create mode 100644 tests/studio/install/test_studio_deps_cli.py create mode 100644 tests/studio/install/test_studio_extra_matches_requirements.py create mode 100644 unsloth_cli/_studio_deps.py diff --git a/.github/workflows/studio-update-smoke.yml b/.github/workflows/studio-update-smoke.yml index 625c2c7811..047840e41c 100644 --- a/.github/workflows/studio-update-smoke.yml +++ b/.github/workflows/studio-update-smoke.yml @@ -146,6 +146,46 @@ jobs: kill "$PID" 2>/dev/null || true echo "post-update Unsloth /api/health OK" + - name: A complete install reports itself complete + run: | + set -o pipefail + unsloth studio verify-install + unsloth studio desktop-capabilities --json | tee /tmp/caps.json + jq -e '.studio_install_ok == true' /tmp/caps.json + jq -e '.desktop_manageability_version >= 2' /tmp/caps.json + + - name: An incomplete install must not report itself ready + # An installer killed part-way leaves a working CLI but no studio.txt + # deps, which the old preflight called ManagedReady.

It now leaves it running, like switching to the Train or Export tab: the sidebar shows which chats are still going, and Stop is per conversation. Plain `unsloth studio` launched llama-server with one decode slot, so the admission queue serialised every chat regardless of what the UI did. Both entry points now default to the same slot count as `unsloth studio run`. A model swap still ends every running chat, since they all decode on one llama-server. /load and /unload now refuse with 409 and name those chats unless the caller passes force_cancel_active, and the UI asks first. * [pre-commit.ci] auto fixes from pre-commit.com hooks for more information, see https://pre-commit.ci * fix(studio): scope the composer tool badge to its own conversation The green "Running Python: ..." badge above the composer read a single global store value, so one chat's tool call showed above every other chat's composer, including a brand-new empty one. Its elapsed counter also restarted at 0 on every thread switch, and a run ending anywhere cleared the badge everywhere. Key the status by thread and store the moment it started, so each conversation shows only its own tool call and the counter resumes rather than restarts. Also adds a test that every conversation gets its own tool sandbox directory, which parallel tool calls depend on. * Fix stalled tool calls while awaiting approval for PR #7455 Three problems, all from the approval prompt behaving as though only one chat could ever run. Arguments were not streamed for a gated call, so the chat stayed blank for as long as the model took to write the payload, which for a large file is minutes. Nothing runs before the decision either way, and the code is what is being approved, so python and terminal now stream their card while gated. render_html stays suppressed: its card renders the payload. The status read "Running ..." with a climbing timer while the call had not started. It now reports that it is waiting for approval, then switches to running once allowed. The admission lease was held across the wait, so four unanswered prompts held all four decode slots and no other chat could start while llama-server sat idle. A parked run keeps its lease but no longer counts against capacity. Measured with four prompts left open: every gated call streamed its code, none reported running, and a fresh chat answered in 0.4s where it previously waited 290s and never did. * Fix duplicated and truncated tool cards for PR #7455 A gated tool call rendered two cards: the provisional one that streams the arguments, plus a second one keyed by the approval id. Only the second ever got its tool_end, so the first spun "Running" for the rest of the chat. Reuse the open part when the approval prompt arrives. The terminal card also showed nothing but a 60-char trigger label, so a long heredoc read as no progress at all. It now renders the command the same way the Python card renders its script, and neither is capped at 10k chars. Both cells moved inside the collapsible, so one chevron hides the code with the output and Copy / Download exist only while the card is open. A card parked on the prompt says so instead of counting up "Running". * Fix review findings on the parallel-chat gate for PR #7455 Backend: - /unload rechecks active generations under the lifecycle gate, like /load, and lets its 409 through the catch-all instead of rewriting it as a 500. - /load gates only once _load_model_impl has decided this is a real reload, so an Apply on the already-loaded model no longer refuses, and the retry it asks for no longer cancels every chat before returning already_loaded. - The direct /v1/responses stream registers in the cancel registry, so a non-forced unload can no longer tear llama-server down under it. - run_server defaults to the same slot count as the CLI. colab.py calls it without the argument, so Colab was still serialising every chat. Frontend: - Cancelling a backgrounded chat aborts its own request rather than only posting a cancel id, which is the only thing that ends an external-provider or audio run. - The model-swap dialog counts local runs only, and falls back to the backend when this tab's map is empty, so a reload or a second tab still gets asked. - Context usage and the diffusion canvas are scoped to the chat that produced them; a compare row reads activity from its member threads. Tests: - The extracted-source cancel harnesses supply the active-generations module, which the tracked-cancel class now depends on. * Fix the swap confirmation scope and cancel timing for PR #7455 A forced load cancelled every chat before the model identifier, GPU selection, training coexistence and download checks had run, so a load that then failed those checks stopped the chats and replaced nothing. The refusal still happens early, but the destructive cancel now sits immediately before the teardown it is paying for, and rechecks under the gate like /unload does. The swap dialog only reconciled with the backend when this tab looked idle, so one local chat was enough to hide a second tab's runs. Confirming then sent force_cancel_active, which cancels every backend run, including the ones the dialog never mentioned. The backend snapshot is now merged in every time, so the dialog names what will actually stop. External-provider runs are never registered there, so the union stays local-only. Also drops the active-generations docstring claim about restoring sidebar spinners, which nothing consumes. * Defer destructive cancels and track every local stream for PR #7455 /unload cancelled the running chats before it had resolved that it unloads anything. A stale model_path, which a second tab produces routinely, killed every chat and then no-opped, leaving the resident model up. It now refuses early and cancels only at each teardown, matching /load. The swap dialog also stopped every chat locally the moment the user confirmed, which threw away the two-phase backend behaviour: a load that then failed identifier resolution, GPU validation or the training guard had already truncated the replies. The backend now owns the cancel. Three local streams decoded on llama-server without registering, so a non-forced unload counted zero generations and tore the server down mid response: /v1/completions streaming, and the plain and server-tool Anthropic streams, the first of which is the default /v1/messages path. Note this makes a non-forced load return 409 during those runs rather than draining quietly, the same trade the /v1/responses fix made. The safetensors tool loop still announced a gated call as running while it waited on a human; only the GGUF loop had been fixed. A source-level parity test now pins both. Also drops stopAllChatThreads, which has no callers left. * Studio: close three load/unload gate races found in review Re-check the in-flight load guard after the stop-running-chats confirm. The confirm always GETs active-generations before its zero-running early-out, so the guard no longer sits atomically ahead of the reservation and two picks in that window both reached performLoad over the same refs. ejectModel had the same shape and gets the same re-check. Reject a sidecar swap immediately before the forced cancel in both load branches. The previous check was back at the top of preflight, so an install reserving during identifier resolution, the tier probe, the training guard or the download check made the post-drain recheck 409 a load whose chats had already been stopped. Enter the Anthropic passthrough's cancel tracker inside its body generator. It was entered eagerly and returned through _sse_streaming_response, which sets no unstarted_cleanup, so a response whose body never started left the run registered forever and 409'd every later non-forced load and unload. * [pre-commit.ci] auto fixes from pre-commit.com hooks for more information, see https://pre-commit.ci * Trim comments across the files this PR touches Tightens the comments and doc blocks in the backend, CLI, tests and frontend files changed by this PR: collapses multi-line explanations to a single line where they still read clearly, and drops the ones the code already says. No code changes, verified by an AST comparison against the previous commit. * Studio: defer the destructive cancel and close two gate gaps Move the forced cancel behind every check that can still reject a swap. The drain now runs first with the runs it is about to cancel discounted, so it waits only for inference the cancel cannot end, then the sidecar check decides, then the cancel fires, then a second drain lets those runs unwind before teardown. A sidecar install reserving during the drain no longer 409s a load whose chats have already been stopped. Track the non-streaming /v1/completions proxy. It was the last local decode path missing from active_generations, so an unload, which runs no drain, tore llama-server down under it and force_cancel_active could not signal it. It now uses the same tracked cancel event and dedicated client as the OpenAI pass-through. Skip the client's preliminary unload while chats are generating and let /load evict at its own post-preflight point instead. Forwarding force_cancel_active there truncated replies before identifier resolution, the GPU and training guards and the download check had run. Keep per-thread context usage so returning to a chat whose background run finished restores its bar instead of leaving it blank until the next turn. Make the running-flag clear run-specific. Every run without a resolved thread id shares the "__default" key, so concurrent compare panes could clear each other's flag and strand a live stop handle. * [pre-commit.ci] auto fixes from pre-commit.com hooks for more information, see https://pre-commit.ci * Studio: register the embeddings proxy with the swap gate /v1/embeddings proxied straight through the pooled client with no tracked cancel event, so it never appeared in active_generations. /unload runs no idle drain, so a concurrent non-forced unload counted zero generations and killed llama-server mid-request, and force_cancel_active had no event to signal. Mirrors the completions proxy: tracked event, dedicated unpooled client closed by a cancel/disconnect watcher, unregister in a nested finally so a close failure cannot leave a phantom generation behind. * Trim comments on the newest changes in this PR Comments only, no code changes: shorten the ones added by the load-gate ordering, embeddings and per-thread usage work down to the same density as the rest of the diff. * Studio: register the legacy generate stream with the swap gate /generate/stream built a cancel event but never entered the tracker, so it was invisible to active_generations. Being in the keep-warm middleware's inference suffixes only covers /load, which drains; /unload does not, so a non-forced unload passed the 409 gate and then blocked on the standard backend's generation lock, and a forced swap had no event to signal. Registered inside the body generator under a nested finally so a teardown failure cannot skip the unregister. The AST contract test asserted the cleanup finally by overwriting its flag per Try node, so a nested try made the last one win. Accumulate instead, which is what the existence claim meant. * Studio: three more swap-gate gaps found in review Register /audio/generate with the gate. TTS holds the model for the whole request and /unload runs no drain, so unregistered a non-forced swap counted zero generations and tore the model down mid-generation; the orchestrator path only waits 15s for the generation lock, which real TTS exceeds. No cancel keys: no backend takes a cancel_event for audio, so the event has no observer and a forced swap still cannot interrupt audio already in flight. Thread the tracked cancel event into the /v1/responses admission wait. It was the only admission caller passing None, so a queued run could not be reached by cancel_all() and a plain /inference/cancel could not stop it at all. Same omission fixed at the upstream send there and on /v1/completions. Let an unforced unload of a stale model path reach the no-op check. Before this PR that request returned 200 and did nothing; the new gate refused it with 409 for a request that reaches no teardown branch. Gate both refusal passes on the disjunction of the route's own teardown conditions, including not is_loaded, so a mid-load GGUF still refuses. * [pre-commit.ci] auto fixes from pre-commit.com hooks for more information, see https://pre-commit.ci * Studio: register the remaining non-streaming decode paths stream defaults to false on all three of these, so they are the ordinary shape of their routes, and each holds a local backend for the whole request. /unload runs no idle drain, so with no registry entry a non-forced swap counted zero generations and tore the backend down mid-request instead of returning 409, and a forced one had no event to signal. Non-streaming /v1/messages: all three helpers ran with an empty registry, since only the streaming siblings were tracked. Registered at the call site because the pass-through takes no cancel_event of its own, and with no cancel keys, matching those siblings. Non-streaming standard chat and audio-input chat: the trackers in this route sit inside their `if payload.stream:` arms, so neither else branch was covered. The GGUF sibling already registers its own non-streaming branch. Each exit is in a finally on the branch's existing try, so the except arms are covered too: a leaked entry 409s every later swap until restart. * Studio: tighten the swap-gate comments Comment-only pass over the newest swap-gate registrations: collapse the multi-line rationales in /unload, the legacy generate stream, audio generation and the non-streaming chat branches, and the matching test preambles, to the shortest form that still carries the reason. No code changes. * Studio: stop the reselect dialog promising a stop that never happens Picking an external provider leaves the local model resident and stops the status poll mirroring it, so reselecting that model showed the stop-chats dialog, and /load then answered already_loaded ahead of its cancel hook. Confirmed with the live backend: the same pick with force_cancel_active set still returned already_loaded and the chat kept streaming. Not stopping those chats is right, since the load never interrupts them, so remove the prompt rather than honour it. Blanket-skipping is unsafe, because the same id and variant with one sampling setting changed is a real reload and 409s, so the branch only fires when a status fetch confirms the resident checkpoint and variant match, and then adopts it without calling /load. Redact native model paths from the active-generations response. Registering /generate/stream recorded backend.active_model_name verbatim, which is an absolute path for a native local model, and this route is the only place that serialises it. Redacting at the response covers every tracker rather than the one that surfaced it. * [pre-commit.ci] auto fixes from pre-commit.com hooks for more information, see https://pre-commit.ci * Studio: keep hydrated context usage in the per-thread map The history loader restores a saved conversation's usage through setContextUsage only, and it runs once per mount, so switching away and back left the bar blank for a hydrated chat even after the per-thread map landed. setContextUsage now writes the value through to the visible thread's own entry and clears that entry when passed null, which covers both hydration call sites and any future writer. * Studio: unblock load cancellation and share unresolved thread keys Run the two stop-loading fast paths ahead of the unload route's pre-gate refusal. _unload_may_evict returns True for exactly the model being cancelled, so the refusal was blocking the branch that cancels a load which has replaced nothing and can interrupt no chat. The client made that unrecoverable: cancelLoading sends the unload without force, drops the result, and its abort never reaches /load, which takes no signal, so the load ran on and could later cancel those chats and swap the model. Nothing else is exempted; an unload that would tear down a serving model matches neither fast path and still 409s. The comment claiming the client lets that 409 surface is corrected, since it discards it. Hold every owner behind a shared thread key. Runs with no resolved thread id share "__default" (concurrent compare panes, since startCompare clears activeThreadId), so a single owner slot let a second run replace the first's token and then delete the shared entry while it was still generating, and the server-cancel map lost the older handle the same way. Both now hold a list, the running and local flags survive until the last owner clears, and stopChatThread stops every handle under the key. * [pre-commit.ci] auto fixes from pre-commit.com hooks for more information, see https://pre-commit.ci * Studio: carry a confirmed swap into the sidecar install, key restored usage by thread Picking a model that needs a newer transformers while chats generate raised the "stop N chats" prompt, but the answer never reached the install that runs before the load: /install-latest-transformers refused on those same chats and took no force flag, so Retry hit the same 409 and nothing in the flow stopped them. Carry force_cancel_active through the consent dialog into the installer. Only the pre-gate fast path is skipped: the recheck under the lifecycle gate still has to pass, so an unconfirmed caller is refused as before. The cancel runs last inside the gate, after every check that can still reject the install, and the drain behind it is bounded since it holds the gate and the sidecar reservation. Also key restored context usage by the thread the loader read. history.load() captures remoteId before two awaited round trips, so a switch inside that window filed one thread's usage under another and setActiveThreadId kept re-applying it. Preserve sibling owners when a run key is cleared without an owner: the image rejection gate now uses its own token, and the reducer leaves owned runs alone. * [pre-commit.ci] auto fixes from pre-commit.com hooks for more information, see https://pre-commit.ci * Studio: bound the post-cancel drains, and make cancellation reach the paths that ignored it A forced swap cancels the chats it interrupts, then waits for them to unwind. That wait had no deadline while holding the lifecycle gate, and TTS on the subprocess backend observes no cancel event at all, so one audio generation could pin every load, unload and new request for its whole duration. Bound both post-cancel drains. Pre-cancel drains stay unbounded: the swap can still be refused there, so shortening them would weaken what they protect. /unload had the opposite problem and no drain at all, cancelling and tearing down on the next line, which turned a clean stream end into a dropped connection. Give it the same bounded wait, gated on the cancel having cancelled something so an idle Eject pays nothing. Make the cancel actually land where it can. GGUF TTS now takes a cancel_event and a watcher closes its client to break the blocking POST. The Anthropic non-streaming pass-through did the same thing the completions and embeddings paths used to: register with the gate, then run both POSTs on the pooled client that cannot be closed. It now uses a per-request client like they do. Also: park and unpark the admission queue the reservation actually holds, since queues are keyed by base_url and a reload mints a new port; key tool output by remoteId on both sides, so the first turn of a New Chat stops writing under one key and reading another; and give tool status a run owner, so a finishing run cannot blank the badge a concurrent one is still showing. Clamp --parallel to 1 on a llama-server without --kv-unified. The new default of 4 would otherwise split -c four ways on such a build, quartering the context window for a feature it cannot serve. * [pre-commit.ci] auto fixes from pre-commit.com hooks for more information, see https://pre-commit.ci * Studio: scope a chat's Stop to its own generation, and clear the way before a confirmed install Safetensors generation is serialized on _gen_lock and the worker has a single cancel event, so a chat still queued on that lock owns no generation. Its Stop handler called reset_generation_state() anyway, which set the shared event and ended whichever conversation was actually running. Parallel chats is what makes that reachable. _generate_inner now records its cancel_event as the current holder once it takes the lock, and reset_generation_state drops a reset from anyone else. Every route call site passes its own request event. A reset with no event stays global, so unload and model switch cannot leave a generation alive, and a reset while nothing runs still resets, so an error path before generation is not a no-op. The other two backends take the argument too, or the standard one raises TypeError on every cancel. The sidecar install had the mirror of the /load ordering problem: it cancelled the chats first and drained second, so an unrelated counted request the cancel cannot reach (a count_tokens, say) was still there for the recheck, which then refused an install that had already stopped every chat for nothing. Drain the unreachable remainder first, discounting the registered chats, then cancel. * [pre-commit.ci] auto fixes from pre-commit.com hooks for more information, see https://pre-commit.ci * Studio: close the windows the previous round's fixes left open Three follow-ups, two of them holes in the fixes just before them. The worker claim went in after _send_cmd, so the command was already running unclaimed and a queued chat's Stop in that window still reset it. Claim first, with the send inside the same try, so a failed send releases it too. Tool status kept one entry per key with an owner. That stops a foreign clear but not an overwrite: under the shared unresolved-thread key the second run replaced the first's entry, and its own clear then removed the only one while the first tool was still running. Keep per-run entries and render the newest. /unload gated its drain on having cancelled something, so a request that passed the keep-warm middleware but had not reached its tracker yet was invisible to it and the teardown landed on an already-admitted request. Drain on the middleware count instead, which covers that window as well as the cancelled runs, then re-cancel whatever registered while waiting. Bounded, not a refusal: an unload is deliberate, and on expiry it proceeds exactly as before. * [pre-commit.ci] auto fixes from pre-commit.com hooks for more information, see https://pre-commit.ci * Trim the parallel-chats comments to their reasons Compress the multi-line rationales added by this branch into shorter forms and drop restatements of the code below them. The reasons behind the drain bounds, the deferred cancel, the per-request generation ownership and the thread-scoped tool and usage keys are kept, just said in fewer lines. * Studio: own the worker per generation, and make a resumed chat requeue for its slot Ownership was a single lock holder, so dispatched runs (compare mode bypasses _gen_lock by design) never claimed it and the guard fell straight through to the global reset: a Stop on one of them ended its siblings. Track the generations actually running instead, claimed before the send and released in the same finally on both paths. A reset still proceeds when nothing is running, so an error path ahead of generation is not swallowed. park() hands the freed slot to a waiter, so a chat resuming from a tool approval could take it back while that waiter was still decoding, putting two holders on a one-slot server and sending the resumed tool loop past the admission limit. unpark_async waits for room; the plain unpark stays for a holder tearing down, which will not decode again. Audio only observed its cancel event on a forced swap. An explicit Stop just aborts the fetch, and this route has no cancel id, so llama-server ran on to the request timeout after the chat reported it stopped. Watch the disconnect. Also read tool status by remoteId, matching the key the adapter writes and the fix already made for tool output, and stop an unresolved run from writing its usage into whichever conversation the user moved to. * [pre-commit.ci] auto fixes from pre-commit.com hooks for more information, see https://pre-commit.ci * Studio: let only the generation the worker is running speak for it, and hold a slot for a resuming chat The ownership list recorded admission, but the subprocess runs generations one at a time, so a dispatched request queued behind another counted as an owner and its Stop signalled the shared cancel event, ending the request that was actually running. Keep admission for release bookkeeping and gate ownership on execution instead, promoted when the worker first answers that request. Nothing executing still permits a reset, so an error path ahead of generation is not swallowed. The worker has one cancel event and no per-request cancellation, so this decides who may pull the lever rather than making the lever per-request. A resuming chat also polled for a slot it could never see: release() grants to the next waiter under the same lock, so later arrivals overtook an approved chat indefinitely. A pending unpark now reserves the next slot and they queue behind it. * [pre-commit.ci] auto fixes from pre-commit.com hooks for more information, see https://pre-commit.ci * Studio: cover the prefill window, and keep a first turn's tool output readable Gating worker ownership on execution left the interval between the send and the first response uncovered: nothing is executing then, and the empty case admitted anyone, so a queued chat's Stop still ended the one in prefill. Split the empty case. Nothing claimed at all still permits a reset, so an error path ahead of generation is not swallowed; claimed but unanswered resolves to the oldest claim, which is what a FIFO command queue is working on. Putting both sides of the tool-output scope on remoteId left the first turn of a New Chat writing under the unresolved scope for its whole life while the readers recomputed the moment the autosave assigned an id, so the card blanked mid-run. The readers now fall back to the unresolved scope, which only an unpersisted first turn can occupy. * Studio: order the parked approvals, and tie a worker claim to its enqueue The reservation added for admission fairness was a bare count, so every approved holder counted against every other: park two chats, approve both, and once the last decoder released, nothing could ever satisfy the check again. That is a deadlock where the problem it fixed was only unfairness. Make it a FIFO ticket so a pending unpark blocks the ones behind it and no others. _owns_worker reads claim order to decide which request the worker is prefilling, which only holds if claiming and enqueuing cannot interleave. Hold one lock across both on the dispatched and the locked path. * [pre-commit.ci] auto fixes from pre-commit.com hooks for more information, see https://pre-commit.ci * Studio: follow a first turn's run when its thread gets an id, and key the denoising canvas per chat A run started before its thread existed filed every handle under "__default". Nothing moved them once autosave assigned the real id, so the sidebar row showed no spinner and Stop could not reach the generation, which kept holding a slot. adoptDefaultThreadRun re-keys the run maps onto the real id from the thread adapter's initialize(), where the id first exists; anything already filed under that id wins, since that is a later run. The adapter captures its key once at run start, so it now resolves the live key per use through runKeyForOwner, looking its own serverCancel up in the owner map. Without that the migrated entries are stranded and the spinner never clears. The denoising canvas was one global slot, so two diffusion chats overwrote each other and the ownership tag then hid the visible preview until that thread emitted again. It is now activeDiffusionCanvasByThreadId, written and cleared per thread, and the frame no longer carries a threadId of its own. The bubble reads threadListItem.remoteId, dropping the dead threadListItem.id arm: the writer tags unstable_threadId, which is exactly remoteId. Two existing backend tests needed the same treatment. _bare_orchestrator skips __init__, so it now sets the claim bookkeeping the worker ownership check reads. The Anthropic passthrough gate test anchored on comment prose that a rewrap had broken; it anchors on the code instead. * Studio: hand the worker over cleanly between generations, and stop unresolved runs sharing each other's state Worker ownership moved off the consumer and onto the dispatcher. Consumers read their mailbox whenever they get around to it, so a request whose gen_done had been routed still owned the worker while the next one ran, and a late Stop for it cancelled that one. The dispatcher is the only place responses arrive in the order the worker produced them: it now retires a request at its terminal response and promotes the next one, and answering a request makes it the sole executor, since the subprocess runs one generation at a time. reserve()'s immediate path ignored the unpark tickets that _grant_waiters_locked already honours, so a request arriving between a slot freeing and an approved chat's next poll took it, repeatedly. It applies the same reservation now. Three places let concurrent first turns share state through the "__default" key. Nothing links a run filed there to the id its thread later receives, so rather than guess, each now declines when the key is ambiguous: adoption only re-keys a lone run, the composer badge only claims a lone status, and the tool-output fallback only applies to a thread that is still running. That leaves two concurrent first turns where they were before adoption existed instead of handing one thread the other's handles. A first turn's usage was never filed, because its key stayed null for the whole run while autosave moved activeThreadId to the real id, so the context bar went blank after the first reply. It resolves the adopted key like the cleanup handles do. Cancelling a forced load left the UI with no model: the previous one stays resident until /load's teardown, and the cancel path cleared the checkpoint without rolling back. It now resyncs from the backend, which is right whether or not the load got that far. The sidecar install drain is weighted 1:4 rather than halved, total unchanged. Only the second half benefits from patience, and cutting it short refused installs whose chats had already been stopped for nothing. * [pre-commit.ci] auto fixes from pre-commit.com hooks for more information, see https://pre-commit.ci * Studio: give a first turn its real thread id before the run starts A first turn filed every run handle under a shared unresolved key because assistant-ui binds unstable_threadId before the thread is persisted. Two of them overlapping there is unresolvable afterwards, and the last round's migration could only decline rather than guess, which left neither sidebar row showing its run. The id is available earlier than I claimed. append() already tracks threadListItem.initialize() by the user message id, and createPersistedRunAdapter already awaits that promise before invoking the adapter, so the thread is persisted by the time the run begins. It was only being discarded: the tracked promise resolved to void. It now resolves to the assigned id, and the wrapper hands it to the adapter when assistant-ui had none. An id that is already set is never replaced, since that would move a running chat's handles out from under the row watching them. The existing unresolved-key guards stay as a safety net but should no longer carry weight. The sidebar counted running thread ids rather than rows, so one compare conversation read as two chats. It folds ids into rows through the same threadIds the row spinner uses, and still counts a running id that matches no row. _TrackedCancel always registered kind="chat", so an embeddings or raw completions request appeared in the model-swap prompt as an unnamed conversation and confirming cancelled it while calling it a chat. The non-conversation routes now pass their own kind, and the prompt says "requests" whenever the snapshot is not all chats. * [pre-commit.ci] auto fixes from pre-commit.com hooks for more information, see https://pre-commit.ci * Studio: withhold the shared worker cancel from a request the worker has left Moving ownership to the dispatcher fixed reset_generation_state, but the token loop signals the shared worker event directly and did not carry the same rule. A dispatched consumer runs with mark_started off and can still be draining tokens buffered before its gen_done was routed, so stopping it there ended whichever request the worker had started next. It now signals only when _owns_worker agrees, the same predicate reset_generation_state uses. The local drain and return are unconditional, since those touch nothing but this stream. The remaining _cancel_generation callers are deliberately global: subprocess shutdown, the pre-load kill and unload_model. * Studio: add the AGPL-3.0 header to the first-turn identity test * [pre-commit.ci] auto fixes from pre-commit.com hooks for more information, see https://pre-commit.ci * Studio: stop the dispatcher and a _gen_lock stream fighting over the response queue Nothing stopped the dispatcher starting under a _gen_lock generation, so once compare was opened while an ordinary chat was still streaming, both consumed _resp_queue and whichever response the dispatcher took without a mailbox was dropped, gen_done included. That chat truncated or hung. This PR is what makes it reachable, since navigating into compare no longer ends the chat behind it. Delaying the dispatcher would serialise compare behind whatever chat happens to be streaming, so the direct readers get a mailbox instead. _direct_reader returns a reader, a cancel drain and a release, and files the mailbox under _direct_mailboxes rather than _mailboxes, which means "compare requests are in flight" to the unload and distributed paths and must not count an ordinary chat. Both directions close. The dispatcher finds the direct reader's mailbox instead of dropping. And this reader can already be blocked on the queue when a compare request's dispatcher starts, so a response that is not ours goes to its own mailbox rather than being consumed, which would have corrupted the chat and hung the pane. All three _gen_lock readers use it, and the cancel drain goes through it too. The sidebar's return target still picked a raw pane id while the count grouped by row, and /chat addresses compare with `compare`, not `thread`. It resolves through the same items now, so a running compare row returns to its pair. * [pre-commit.ci] auto fixes from pre-commit.com hooks for more information, see https://pre-commit.ci * Studio: keep worker ownership honest across audio, API traffic and a replaced worker The audio-input send got a mailbox last round but stayed unclaimed, so a compare request queued behind it looked like the oldest owner and stopping that queued request signalled the shared event into the audio chat. It claims under the send lock and releases in the finally, like _generate_inner. Ownership is keyed on cancel-event identity with nothing tying it to a worker generation, so a consumer still blocked on its mailbox when the process was replaced stayed recorded as the executor, and a generation on the fresh worker could not be stopped. _shutdown_subprocess clears that state once the process is confirmed dead, mailboxes included: nothing routes to them again, and a stale one reads as compare activity to the unload path. Not on the survived-SIGKILL path, which keeps its handle on purpose. The four public /v1/messages trackers were registering as chats. The distinction is a Studio thread, not the protocol, and those branches already say "No thread_id: public API surface" while the Studio path passes payload.thread_id separately. They carry their own kind now, so the swap prompt stops calling an external request a chat. The swap confirmation still counted raw pane ids, so a compare conversation asked to stop two chats and listed its title twice. It folds panes onto pairId and lowers the count by what it collapsed, leaving a first turn the backend can count but not name. Deep Research set runningByThreadId but registered no server-cancel handle, and that map is how Stop, archive and delete reach a thread that is no longer active. Leaving the outgoing thread running is this PR's doing, so the run was left unreachable while its supervisor kept working against a conversation the user could delete. * [pre-commit.ci] auto fixes from pre-commit.com hooks for more information, see https://pre-commit.ci * Studio: tighten the parallel-chats comments * Studio: replay a Deep Research stop that arrived before the run existed The handle is registered before createResearchRun resolves because the thread can be stopped while that request is in flight, but it had no id to act on and dropped the stop. The supervisor then followed a run the user had already stopped, archived or deleted. It latches instead: a stop with no id yet sets a flag, and the adapter replays it against the id the moment creation returns rather than starting to follow. * [pre-commit.ci] auto fixes from pre-commit.com hooks for more information, see https://pre-commit.ci * Studio: fix worker ownership on a raced reroute, and the stop-chats prompt Four review findings on the parallel-chats work, all reproduced first. - _direct_reader hands a foreign response to its own mailbox, but skipped the ownership move the dispatcher makes. A _gen_lock reader already blocked on resp_queue can beat the compare dispatcher to that request's first response, and the compare consumer opts out of marking, so nothing promoted it: the direct request stayed the recorded executor, its late reset cancelled the compare generation, and the compare chat's own Stop was ignored. - A chat stopped while queued on _gen_lock was still claimed and sent once the lock freed. Cancellation is only checked on a token, so a long prefill, or a generation reaching gen_done without one, occupied the worker after Stop. Same hole in the audio-input path, which shares the lock. - The stop-chats prompt counted generation handles, not conversations. One chat holds several while a tool continuation registers its next leg before the previous unwinds, so it offered to stop two chats and listed one title. - Ejecting a model confirms through that dialog, which told the user "Unloading the model reloads the model" and offered "Stop and reload". Confirming calls /unload and leaves nothing loaded. * [pre-commit.ci] auto fixes from pre-commit.com hooks for more information, see https://pre-commit.ci * Studio: name the TTS run's thread so the stop prompt counts it once The audio branch registers its run locally under the thread key but sent no thread_id, so the backend tracker filed the same generation under no thread. The stop-chats prompt then had a named local run and an unnamed backend one and, since e8e7594 started adding unnamed entries to the named ones, counted a single TTS chat as two requests. The backend already reads payload.thread_id, so sending it lines both registries up on the same run. * [pre-commit.ci] auto fixes from pre-commit.com hooks for more information, see

The tracker wrote a group's duration once and never revisited it, so such a group froze at its first close and displayed 0 seconds. Measure from the first time an index becomes visible rather than from the last startGroup, and reopen a closed group while its reasoning text is still growing. Gating on growth is what stops the timer running on into the answer. A duration supplied by the server is now recorded as authoritative so local timing cannot overwrite it. Also fill indices that a single delta skips. startGroup(n) could jump past earlier indices and leave array holes, which JSON.stringify persists as null; a skipped group became visible and closed inside the same chunk, so it gets a measured zero instead. Test discovery now globs tests/, so a second test file cannot be silently skipped by CI, and tsconfig.test.json puts tests/ under typecheck for the first time. --------- Co-authored-by: pre-commit-ci[bot] <66853113+pre-commit-ci[bot]@users.noreply.github.com> Co-authored-by: danielhanchen --- .github/workflows/studio-frontend-ci.yml | 3 + studio/backend/core/inference/llama_cpp.py | 15 +- .../backend/tests/test_llama_cpp_tool_loop.py | 39 +-- studio/frontend/package.json | 3 +- .../src/components/assistant-ui/reasoning.tsx | 11 +- .../src/features/chat/api/chat-adapter.ts | 177 ++++++------- studio/frontend/src/features/chat/index.ts | 1 + .../chat/utils/parse-assistant-content.ts | 76 +++++- .../features/chat/utils/reasoning-duration.ts | 218 ++++++++++++++++ .../frontend/tests/reasoning-duration.test.ts | 236 ++++++++++++++++++ studio/frontend/tsconfig.test.json | 28 +++ 11 files changed, 684 insertions(+), 123 deletions(-) create mode 100644 studio/frontend/src/features/chat/utils/reasoning-duration.ts create mode 100644 studio/frontend/tests/reasoning-duration.test.ts create mode 100644 studio/frontend/tsconfig.test.json diff --git a/.github/workflows/studio-frontend-ci.yml b/.github/workflows/studio-frontend-ci.yml index 3a9e373915..773e555c8b 100644 --- a/.github/workflows/studio-frontend-ci.yml +++ b/.github/workflows/studio-frontend-ci.yml @@ -133,6 +133,9 @@ jobs: - name: Typecheck run: npm run typecheck + - name: Unit tests + run: npm test + - name: Build run: npm run build diff --git a/studio/backend/core/inference/llama_cpp.py b/studio/backend/core/inference/llama_cpp.py index a23501a6eb..be0b1596ad 100644 --- a/studio/backend/core/inference/llama_cpp.py +++ b/studio/backend/core/inference/llama_cpp.py @@ -11392,6 +11392,7 @@ class LlamaCppBackend: # Time each reasoning pass so final answers can replace tool timing. _reasoning_started_at = None _reasoning_summary_emitted = False + _deferred_reasoning_summary = None cumulative_display = "" # Cumulative yielded text (with ) in_thinking = False has_content_tokens = False @@ -11643,7 +11644,11 @@ class LlamaCppBackend: and not _reasoning_summary_emitted ): _reasoning_summary_emitted = True - yield _reasoning_summary_event(_reasoning_started_at) + _summary = _reasoning_summary_event(_reasoning_started_at) + if _suppress_visible_output: + _deferred_reasoning_summary = _summary + else: + yield _summary has_content_tokens = True content_accum += token @@ -11927,7 +11932,11 @@ class LlamaCppBackend: # route's extractor closes the streamed ). if _reasoning_started_at is not None and not _reasoning_summary_emitted: _reasoning_summary_emitted = True - yield _reasoning_summary_event(_reasoning_started_at) + _summary = _reasoning_summary_event(_reasoning_started_at) + if _suppress_visible_output: + _deferred_reasoning_summary = _summary + else: + yield _summary cumulative_display = _finalize_reasoning_only_cumulative( cumulative_display, reasoning_accum, @@ -12041,6 +12050,8 @@ class LlamaCppBackend: "type": "content", "text": forced_visible_text, } + if _deferred_reasoning_summary is not None: + yield _deferred_reasoning_summary elif not _suppress_visible_output: # Turn ended as a plain answer (no [ARGS] followed): the held # rehearsal tail is real prose, release it. diff --git a/studio/backend/tests/test_llama_cpp_tool_loop.py b/studio/backend/tests/test_llama_cpp_tool_loop.py index 7b20063892..c629ff3be4 100644 --- a/studio/backend/tests/test_llama_cpp_tool_loop.py +++ b/studio/backend/tests/test_llama_cpp_tool_loop.py @@ -602,7 +602,7 @@ def test_consumed_tool_final_pass_emits_latest_reasoning_summary(monkeypatch): ] payloads: list[dict] = [] backend = _make_backend(monkeypatch, [tool_stream, final_stream], payloads) - _patch_monotonic(monkeypatch, [200.0, 201.0, 203.0, 300.0, 400.0, 405.0, 405.0]) + _patch_monotonic(monkeypatch, [200.0, 201.0, 203.0, 300.0, 400.0, 405.0, 410.0]) def fake_execute_tool(name, arguments, **_kwargs): return "Rendered HTML canvas: Done." @@ -1495,6 +1495,7 @@ def test_forced_reprompt_plain_final_answer_is_visible(monkeypatch): streams = [ [_sse({"content": "I will use render_html now."}), _done()], [ + _sse({"reasoning_content": "I reconsidered the request."}), _sse({"content": "No tool is needed.

The create path that writes the same file, 26 lines above at 5621, already passes encoding = "utf-8", so main is also internally inconsistent about one file: written as utf-8, read back under the operator locale. Scope, stated honestly: json.dumps defaults to ensure_ascii = True, so the marker this module writes is pure ASCII and round-trips under cp1252 as well as utf-8. The exposure is a marker produced or edited by something else. A decode failure on the read would not even surface, because UnicodeDecodeError subclasses ValueError and the surrounding except (OSError, ValueError) swallows it into the early return, leaving the backend silently unsynced. So this restores a green suite and makes the file self-consistent rather than fixing a live crash.

It goes through popen(), so it is a literal `sh -c`, but the terminal scan only ever saw `sed` at command position and treated the program text as an ordinary argument. That left `sed -n '1e rm -f victim' /etc/hosts` running with no prompt in auto mode, and `_find_blocked_commands` returning nothing for it, so the hard blocklist that applies in every mode missed `rm` as well. Screens the program the same way the awk arm does. `-e` values are joined with newlines first, since that is how sed assembles them: `sed -e '1a\' -e 'e CMD'` appends a literal line and runs nothing, so judging the pieces separately would prompt on a benign script. The scan then steps over every region where `e` is data rather than a command: address and substitution regexes, replacements, `a/i/c` text, `r`/`w` filenames, `b`/`t` labels and comments. That keeps the common idioms silent, including `:e;N;$!be` loop labels, `s/e/E/g`, and `s/a/b/we out.txt` where the `e` belongs to the `w` filename and sed does not execute. The blocklist scan recurses into a literal `e` payload the same way it already does for `bash -c`. A bare `e` or an `s///e` can only be prompted, since what they run is the pattern space, which is input-file text that is not knowable statically. Verified against real GNU sed 4.9 rather than the manual: 80 commands run for real with a marker payload, comparing what sed actually executed against the classifier, with no mismatches in either direction. * Close five ways a sed program hid its shell payload Review found five shapes the first pass missed. All five execute on GNU sed 4.9, checked by running them rather than reading the manual. A payload line ending in a backslash continues onto the next line, so the scan now ends an `e` at an unescaped newline and unescapes the text the way sed's read_text does. That is what resolves `r''m` back to `rm` for the blocklist. A sed comment ends at a real newline, but the terminal scan had already replaced every newline with `;`, including newlines inside quotes, so `# comment` swallowed the rest of the program. The sed arm now also sees a variant where only unquoted newlines become separators, built on a character-by-character quote scanner rather than a regex: an apostrophe in a double-quoted word mis-pairs under a regex and inverts the state, which opened a bypass while this was being written. Everything attached to `-i` is a backup suffix, so reading `-ifoo` as an attached `-f` lost the real script. Replaced the shared short-flag helper with sed's own option grammar, which also fixes `-l 5` and `--line-length 5` eating the script as their operand. A sed child of `find -exec` was never recorded, so the blocklist skipped its payload. Substituted text splices straight into the program, and an address is as good a place as any to open `;e CMD`, so a command substitution anywhere in the program is treated as unresolvable. Scoped to the program: a substitution in a file operand still runs, a `$(` or backtick inside single quotes is literal, and parameter and arithmetic expansion are untouched. The cost is that a substitution used to build a program now asks. Bounding the -exec walk keeps the blocklist linear; without it a repeated `-exec sed` line went quadratic. Verified against real GNU sed across 103 commands run for real, no mismatch in either direction. * Fail closed on padded sed lines, and stop gating sed --sandbox Four more from review, each checked by running it rather than reading the manual. The cap that keeps the argument walk linear was itself the bypass: padding a line with 128 valid options pushes the script past it, and an empty program read as proof the command only edits text. The budget is now shared across the sed words on a line, so a lone sed reads its whole argument list while a line packed with sed words keeps the floor that holds the walk linear, and overflow fails closed instead of falling through. The substitution scan counted parentheses without consulting quote state, so a quoted paren in the substitution body left the span unterminated and the program never matched. It now balances through the same quote scanner used elsewhere, since a substitution body reopens quoting. A wrapper between -exec and its child hid the child from the blocklist. Following the wrapper also fixes the neighbouring blocked-name check, which missed find . -exec env rm the same way. The wrapper's own name is still screened: -exec sudo rm reports both. sed --sandbox and --posix refuse e outright and exit 1, so gating them was prompting for something that cannot run. They are now inert, except after --, where the flag is an input filename and the script still executes. env -u still hides a child from the blocklist, on this path and at top level. That is pre-existing and left alone here. * Resolve the sed program through find, wrappers, globs and variables Five more from review, each run against real sed rather than read off the manual. find's -exec ends at + or ;, but the sed argument walk ran past it into the next predicate, where a following -exec grep -e safe was read as sed's own -e and discarded the real script. Stopping at the terminator also removes a false prompt, since -exec was being parsed as -e xec and inventing a payload. Hopping a wrapper skipped its name but not an option that takes a separate operand, so env -u FOO sed returned FOO as the child. The table this file already keeps for wrapper options covers it, moved up so both layers share it. That also settles the top level: env -u PATH rm -rf x now reports rm, as do env --unset, stdbuf -o L and xargs -I {}. Two false positives go with it, timeout -s KILL 5 rm blaming the signal name and env -u kill blaming a variable name, while timeout -s KILL 5 kill -9 1 still reports kill. A program held in a variable was invisible: the assignment regex stops its value at whitespace, so a program containing a newline never entered the map in any pass. Resolved at the token level instead, where the value is already whole. Both the written and the resolved program are screened, since either can hold the e. A command-position glob that can resolve to sed is treated as sed. The auto gate already asks about any unresolved command glob; this is for the blocklist, which did not know the name. Inside double quotes a backslash makes the next character literal, so sed "s/\$(CC)/gcc/" runs no substitution and should never have asked. The quote scanner now reports an escaped character under its own state. Left open: on Windows the blocklist lexer keeps quoting in its tokens, so a multiline program held in a variable resolves there but not to a name the blocklist reads. The prompt still fires on every platform. * Ask when the sed program is not a literal we can read Two from review, and the second one changes the default rather than adding another case. sed --sandbox and --posix were being read as disabling e for the whole invocation. They disable exactly the scripts written after them: sed compiles each -e as that option is parsed, and the positional script only after the option list, so sed -e '1e CMD' input --sandbox runs the payload with no POSIXLY_CORRECT needed. Suppression is now positional. Reading POSIXLY_CORRECT out of the command text was considered and dropped as unsound, since export or an outer bash -c puts it somewhere the text does not show. A program built by a parameter transformation was invisible: only bare $NAME and ${NAME} were resolved, so ${p#x } passed through untouched. Rather than add operators one at a time, a program that still holds a live expansion after resolution is treated as unreadable and asks. Unhandled expansion forms are now safe by default instead of silent, which also closes ${p%Z}, array elements, printf -v, read, and p=$(...) whose binding shlex had been truncating to a bare $. Arithmetic is collapsed rather than exempted. It can only ever evaluate to an integer, so it cannot spell a sed command, but leaving it as written let "$((c+1))e CMD" read as an append-text command that swallowed the payload. The cost is that a double-quoted program holding an unassigned variable now asks: sed "s/$OLD/$NEW/g" f. Measured at 24 of 169 realistic invocations, all of that one shape. Exempting it would trade enumerating expansion operators for enumerating assignment forms, and four of the bypasses above sit outside the assignment pattern, so the blanket rule stays. Left open: -f prog.sed is still unscreened, since the program is in a file. * Decide where a sed scan stops by context, not by token text Four from review, two of them exploiting fixes from earlier rounds. Stopping the sed walk at a + or ; token read the text after shlex had already removed its quoting, so a quoted file operand looked exactly like a find terminator and the scan gave up before the -e that followed. sed still compiles that -e, because getopt permutes. Termination is now decided by token index: a separator counts only if it was unquoted, and + or ; only while a find or fd exec action is open, which is the only place quoting does not matter. The same shape works with & | ( ) and }, so all of them are covered. The assignment map kept the first binding for a name, but the shell uses the most recent one before the command. Bindings are now ordered and only those preceding a given sed are folded in, with a later one replacing an earlier. A value that is not itself literal clears the name rather than leaving the older literal standing, which would otherwise have dressed an unread program up as a safe one. Exhausting the wrapper budget under find -exec returned the same answer as finding no child at all, so a long enough chain of wrappers hid whatever followed. It now reports overflow and blocks the chain word. This was hiding more than sed: the same shape hid a plain rm. fd spells its exec flags -x, -X, --exec and --exec-batch, none of which were routed into the nested scan. They are now, but only while a find or fd word is in scope and no action is already open, so a -x that belongs to a child command is left alone. Prompt rate is unchanged at 45 of 169 realistic invocations; this round adds no new prompts. * Drop the words the shell removes before a command runs Two from review, both verified to run for real. A redirection is performed by the shell and never reaches the command, but the words stayed in the token list and the first of them was taken for sed's positional script, so the real one behind it was never read. `sed `, `2>`, `2>&1`, `&>`, `>|` and here-string spellings. Redirections are now recognised as spans and skipped: the target may be glued on, be the next word, or sit one further along when a punctuation character splits the operator. A skip is honoured only where sed would take the word as an argument, so a pending -e/-f/-l value is still read. The same words also hid a command outright. `> out.txt rm -rf victim` and `2>&1 rm -rf victim` both really delete, because the redirection target was read as the command word and the rm behind it landed in argument position, where the always-on blocklist does not look. shlex emits a RUN of punctuation characters as one token, so bash's `|&` matched no separator and a sed scan ran on into the NEXT command, taking its `-e safe` for the real script and dropping the payload. Any token built only from those characters now ends an invocation, and a quoted one is excluded the same way a quoted `';'` already was. The third item from that review, `-l N` eating the script as its length operand, was already closed in 9a5cfddb. Prompt rate is unchanged at 45 of 169 realistic invocations; this round adds no new prompts. * [pre-commit.ci] auto fixes from pre-commit.com hooks for more information, see https://pre-commit.ci * Read a sed program from what the shell really hands it Five from an independent review pass, each verified by executing it. sed joins its -e and -f sources with newlines, but a source boundary also closes a line continuation open across it. Reading every -e as one uninterrupted text let an unreadable -f in the middle hide the piece behind it: `sed -e '1a\' -f /dev/null -e 'e CMD' input` runs CMD while the same line without the -f only appends text. A program flag ahead of the positional script makes that word an input file. One behind it does so only while getopt permutes, and POSIXLY_CORRECT turns permutation off from outside the command text, so the positional is now read as a script as well. The suppression that a flag written first performs is unchanged. xargs builds the argv of the command behind it, appending what it reads on stdin and substituting it into an -I placeholder, so the program need not be in the text at all. A sed whose program is empty or is only the placeholder is failed closed. The ordinary idioms are untouched: their program is present and the placeholder stands where the file goes. Only a word that really changes shell state rebinds a program held in a variable. An assignment-shaped argument, one inside a subshell and one used as a command's environment prefix all leave the variable alone, and recording them replaced a payload with a value bash never assigned. A conditional assignment after && or || may or may not run, so it clears the name rather than being guessed at. Exec-flag forwarding now starts only at a command word. Any token spelled fd or find used to turn it on, so a -x or -exec in the text after one was read as an exec flag and its neighbour hard-blocked; `echo fd -x rm` and `grep fd -x rm file` were refused outright. A command-position glob bash resolves to find is still recognised. Prompt rate is unchanged at 45 of 169 realistic invocations. * Judge a sed program against what getopt and find really do Seven from review, each verified by executing it. A redirection is removed wherever it stands, including where an option value goes, so `sed -n -e >out '1e CMD' input` takes the word behind it as the script. The skip is now honoured ahead of a pending value rather than after it. The target of a detached redirection may itself look like an option or a quoted operator, and the shell hands it to open() either way, so `sed > --sandbox '1e CMD' input` and its `> ';'` twin no longer leave that word standing as a sed flag or script. Only a bare operator is refused, which is a malformed line. A program flag written behind the positional script and the positional itself are ALTERNATIVES, since permutation decides which sed compiles and nothing in the text settles it. They were joined into one program, where an unterminated command in the one swallowed the other: `-e safe` is an `s` with delimiter `a` and no closing one, and it ate the payload behind it. Each source is now scanned on its own. find closes its batched form at `{} +` only, so a `+` anywhere else is an ordinary argument it hands the child. Stopping at one threw away the script behind it. The `;` spellings need no such test: a quoted `';'` and an escaped `\;` reach find as the same word and it stops at either, which the `;` twin of that line confirms by not executing. An `-f` naming a stream (`-`, /dev/stdin, /dev/fd/N) takes the script off stdin, which the same command line may well supply through a heredoc. That is ignorance rather than safety, so the sed fails closed. A named program file is unreadable in a different way and is unchanged. bash expands the program word before sed is started, so in a directory holding a suitably named file `sed *` runs whatever that file contains. A program word carrying an unexpanded glob now fails closed. Quoted programs expand nothing and a glob among the file operands is not the program, so ordinary work is untouched. Prompt rate is unchanged at 45 of 169 realistic invocations. * [pre-commit.ci] auto fixes from pre-commit.com hooks for more information, see https://pre-commit.ci * Keep command position and quoting intact through the sed scan Six from review, two of them regressions the previous commit introduced. Scoping exec-flag forwarding to a command word lost that position at a shell keyword and across a wrapper's own operands, so `if true; then find . -exec rm ...` and the `env -u FOO find ...` and `timeout 5 find ...` shapes stopped blocking rm entirely. Keywords now keep the position and wrapper options and their operands are stepped over, the way the command walk already does. Reading any operator-shaped token as a separator did the opposite: a QUOTED one is data the command receives, so `printf '%s' '|&' rm` and `grep '|&' rm file` were refused although they run nothing. The walk now applies the same quoted-index exclusion the layout pass does, which also clears the older `printf '%s' ';' rm` false positive. ANSI-C decoding flattened the word's whitespace, and a sed program ends its comment at exactly the newline that flattening destroyed. The decoded text is re-quoted instead, keeping the spaces and the `#` around it, with the newline standing as a mark so it stays data for whatever command receives it rather than a place a new one begins. An assignment inside a function body has not run and may never run, so it is no longer recorded as the current value; the name is cleared instead, which is right whether or not the function is later called. An `-f` taking a process substitution is a generated /dev/fd/N script, and the lexer ends the invocation at the `(` before the operand is read at all. A still-pending program operand now fails the sed closed. Live expansions were compared against the raw command spelling while the sed program carried the post-lex one, so an escaped expansion read as already resolved. Both sides are keyed without their escaping, which can only make a spelling match and so errs closed. Prompt rate is unchanged at 45 of 169 realistic invocations. * [pre-commit.ci] auto fixes from pre-commit.com hooks for more information, see https://pre-commit.ci * Read the sed program from the word the shell actually passes Six from review, four of them bypasses and two false alarms. find rewrites `{}` with the pathname it found before the child ever starts, so a sed whose whole program is that placeholder was never read. Nested under xargs it really runs whatever a suitably named file contains. A `{}` among the file operands, which is the ordinary idiom, is not the program and is untouched. A quoted redirection is a word the command receives rather than something the shell performs, and it was being removed either way, so a `-f` script file named `>prog` disappeared and took the `-e` behind it out of view. Quoting is now read from the operator the token opens with, which leaves `2>'/dev/null'` a redirection with a quoted target. An apostrophe in an ANSI-C word sent it down the flattening path, which destroys the newline a sed comment ends at. The apostrophe is re-quoted the way a shell does it instead. fd takes the command attached to its short exec option, and only the exact `-x` and `-X` spellings opened an action, so `-xrm` reached neither layer. Conversely nothing behind a bare `--` is an option at all, and reading one there refused `fd -- -x rm`, which merely lists a file. The set of live expansions covers the whole command, so matching a sed program against it by text alone attributed an expansion another command performs to a program that only spells the same thing. Which occurrence it was decides it now, and single quoting keeps its meaning while double quoting does not. Prompt rate is unchanged at 45 of 169 realistic invocations. * [pre-commit.ci] auto fixes from pre-commit.com hooks for more information, see https://pre-commit.ci * Tighten the comments this PR added Every comment kept says why a rule exists and, where the reason is a real tool behaviour, names the one command that proves it. What went is narration of the code, the history of how each fix evolved, and the same mechanism re-explained at each site that uses it: it is stated once at the definition now and referred to from there. Docstrings on the private helpers give what they return and the one fact that is not obvious; the worked examples they carried are in the tests, which already run them.

That path exports no UNSLOTH_NO_TORCH, so $NoTorchMode was false, the stale-venv check read the missing torch as a broken venv, and setup tried to delete the venv it was running out of: [ERROR] Could not remove stale venv: Access to the path 'python.exe' is denied. That teardown can never succeed there, because setup.ps1 runs via unsloth.exe out of that same venv. The same gap also let the shared dependency pass reinstall torch from PyPI, unpinned, into a GGUF-only environment. install_python_stack.py now records the mode in the install manifest and setup.ps1 reads it back when no env var is exported, then re-exports a canonical value for the dependency pass (setup.ps1 drops the manifest before invoking it, so the child cannot repeat the lookup). The key is additive and MANIFEST_SCHEMA is unchanged, so existing manifests stay valid and a missing key keeps today's behaviour. Also: - read_manifest() caught only OSError, but UnicodeDecodeError is a ValueError. That is now on the installer's import path, so a manifest re-saved as ANSI or truncated mid-write would abort every install. - The env predicate now trims surrounding whitespace, matching the Python side. - The Windows update smoke workflow asserts the update leaves the venv GGUF-only, which is what would have caught this. Known follow-up, pre-existing: an install killed between the manifest drop and the dependency pass leaves no recorded mode, so a later update still walks the stale-venv path. Closing that needs a marker the installer never drops. * Persist no-torch mode in a marker the dependency pass cannot drop The install manifest alone was not enough. Both setup.ps1 and install_python_stack.py remove it before every dependency pass, and it is only rewritten on success, so a no-torch install interrupted in between left nothing recording the mode. The next update then resolved no-torch as false, read the expected missing torch as a stale venv, and tried to delete the environment whose python.exe was running it, which leaves the install unrepairable from the CLI. Add .unsloth-no-torch next to the existing .unsloth-studio-owned marker, written before the pass and cleared when torch is wanted. setup.ps1 writes it as soon as the mode resolves, so the window between the manifest drop and its own torch install is covered too. Read order stays manifest key first, then marker, so migrating out of no-torch is never blocked by a marker an earlier run left behind. Neither present still reads as "install torch", so nothing changes for installs made before either existed. Also adds the AGPL-3.0 header the new test file was missing. --------- Co-authored-by: pre-commit-ci[bot] <66853113+pre-commit-ci[bot]@users.noreply.github.com> Co-authored-by: danielhanchen --- .../workflows/studio-windows-update-smoke.yml | 25 +++ studio/install_manifest.py | 72 +++++++- studio/install_python_stack.py | 31 +++- studio/setup.ps1 | 66 ++++++- tests/python/test_cross_platform_parity.py | 44 +++++ tests/python/test_e2e_no_torch_sandbox.py | 5 +- tests/python/test_no_torch_filtering.py | 58 +++++- tests/python/test_windows_no_torch_setup.py | 171 ++++++++++++++++++ tests/studio/install/test_install_manifest.py | 77 ++++++++ 9 files changed, 540 insertions(+), 9 deletions(-) create mode 100644 tests/python/test_windows_no_torch_setup.py diff --git a/.github/workflows/studio-windows-update-smoke.yml b/.github/workflows/studio-windows-update-smoke.yml index 42d74d47d2..0dcc828e6b 100644 --- a/.github/workflows/studio-windows-update-smoke.yml +++ b/.github/workflows/studio-windows-update-smoke.yml @@ -198,6 +198,31 @@ jobs: fi echo "update path took the prebuilt fast path" + - name: Update must keep the --no-torch install GGUF-only + run: | + # `unsloth studio update` exports no UNSLOTH_NO_TORCH, so setup.ps1 has + # to recover the mode from the install manifest.

Wrap the rebuild in an explicit transaction so a crash rolls back cleanly and the migration re-runs on the next boot. * Studio: block message edits and regeneration during an active research run After a reload a durable research run is followed by the research store rather than an assistant-ui run, so thread.isRunning is false while research is still active. Message edit, refresh and the edit composer previously gated only on isRunning, which let a normal generation start alongside the running research run. Gate them on the active thread's research state as well. * Studio: keep the plan review mounted through approval Keying PlanReview on planRevision remounted it mid-approve when updateResearchPlan bumped the revision, resetting the local pending flag and re-enabling Start research while the approve was still in flight, which allowed a duplicate approve. Key on runId only. * Studio: drop the redundant deep-research persistence change setCheckpoint already persists Deep Research off for external models at the top of the function, so the added saveBool was a duplicate, and clearing Deep Research from setWebFetchToolsEnabled guarded a state that is not reachable (Deep Research is local-model only while the Web Fetch pill is external-provider only). Revert both to the pre-hardening version. * [pre-commit.ci] auto fixes from pre-commit.com hooks for more information, see https://pre-commit.ci * Studio: harden Deep Research citations, query privacy, and message protection Address review findings in the Deep Research backend: - Escape an unbalanced ")" in citation destinations so a source URL cannot close the markdown link early and inject a second link, keeping balanced parentheses literal. - Match raw-URL citations on whole tokens so a URL sharing another URL's prefix is no longer partially rewritten. - Redact non-global IPv6 addresses in public search queries, matching the existing IPv4 handling. - Detect credential key names after normalizing case and separators so nested openaiApiKey, accessToken, and clientSecret values cannot be persisted. - Reject client edits to server-managed research prompts and reports at the storage layer; only the internal writers pass allow_research_update. - Scope research searches to the first allowed domains instead of dropping site scoping for large allow lists. - Persist the same fetch evidence bound used during live synthesis so a resumed run is not shortened. - Scope run completion so it only replaces this run's message parts. Add regression tests for the above. * Studio: fix Deep Research SSE framing, source counts, and favicon privacy - Normalize the whole SSE buffer so a CRLF split across transport chunks still frames events. - Count web and document sources together in the activity header so a RAG-only run is not shown as zero sources. - Cap the plan editor at the run's configured maxSteps instead of a hard-coded 30. - Add an allowRemoteIcons opt-out to the sources components and disable third-party favicon requests for research sources so visited domains are not leaked. * [pre-commit.ci] auto fixes from pre-commit.com hooks for more information, see https://pre-commit.ci * Studio: address final Deep Research review findings * Studio: fit Deep Research synthesis evidence to loaded context, add opt-in web grounding Size the synthesis evidence budget to the loaded model context so the prompt is not silently truncated on small contexts. When the evidence overflowed the window the report degenerated (it echoed the evidence tail instead of writing); the budget now reserves tokens for the prompt scaffolding and converts the remainder to chars, keeping the full cap when the context is unknown. Add opt-in web grounding for auto-read: read the top search results, ingest them into an ephemeral RAG scope, hybrid-retrieve the passages most relevant to the question with the existing knowledge-base retriever, and fold those chunks into the step evidence. The scope is per call and deleted afterwards, so a user's knowledge base is never touched. Off by default; enable with UNSLOTH_RESEARCH_AUTO_SCRAPE=1. Gated per run by budgets["maxAutoScrape"], so runs created without it keep legacy snippet-only behavior, and grounding is skipped when the loaded context is too small for the prompt. Add tests for the adaptive evidence budget, scraped-text cleaning, the ephemeral web-RAG retrieval and scope cleanup, and the auto-read evidence path. * Studio: read Deep Research synthesis context from the inference orchestrator Make the adaptive synthesis-evidence budget actually engage in the normal Studio architecture. _loaded_context_length read core.inference.inference, the low-level backend that lives in the model subprocess and stays unpopulated in the main web process where the research supervisor runs, so it returned None and the budget silently fell back to the 32000 character cap (leaving the report exposed to the truncation this was meant to fix). Read the inference orchestrator instead, and the llama.cpp backend for GGUF, mirroring routes.inference._monitor_context_length so the budget sizes to the context the API layer serves. Verified on a running server: at a 12288 token load the probe now reports 12288 and the budget adapts to 24576 characters instead of the 32000 fallback. Also: - Reserve context for the generated report as well as the prompt scaffolding (raise the reserve to 4096 tokens) so evidence does not crowd out the output on a small window. - Honor a numeric UNSLOTH_RESEARCH_AUTO_SCRAPE by passing the per-run maxAutoScrape as the page cap to the scraper, instead of always reading the maximum. - Guard the web-RAG connection acquisition so a get_connection failure returns the documented empty result rather than propagating. - Add a synthesis-context test that patches the real backend accessor (not the probe itself) so the production wiring is exercised, plus a scrape page-cap test. * [pre-commit.ci] auto fixes from pre-commit.com hooks for more information, see https://pre-commit.ci * Studio: harden Deep Research query redaction and research autosave - research_runs: extend the opaque-token allowlist so unlabeled Hugging Face (hf_) and GitLab (glpat-) tokens are redacted before a query can reach web search, without over-redacting public model or version ids. - runtime-provider: for a server-managed research message, echo the backend-stored metadata verbatim on autosave. Merging the client metadata re-added client-only fields the server never persisted, so the server-side guard saw a diff and rejected every streamed or snapshot update with 409. * Studio: keep composer tool pills always accessible after merge The merge left the composer line marked always-expanded (data-expanded "true") while the inner pill row was still gated behind composerExpanded, so the Search and Code toggles disappeared once the permission mode was "off" with no other toggle set. Render the primary tool pills unconditionally, matching the always-expanded layout, and drop the now unused composerExpanded and permissionMode locals. Fixes the Chat UI Playwright check that asserts the Search and Code pills stay visible. * Studio: update Deep Research composer contract to always-expanded layout The always-expanded composer no longer routes effectiveDeepResearchEnabled through a composerExpanded expression, so the frontend contract now checks that it gates the Deep Research composer button render instead. * Studio: do not bind a research run to a populated assistant reply create_run adopted any assistant message under the user turn whose researchRunId was unset, including a prior answer reused by a retry. On completion _update_assistant drops the untagged text and source parts, so that answer was silently overwritten. Only bind to an empty placeholder or this run's own message, and reject a reply that already carries content. * Studio: harden Deep Research synthesis budget, prompt shielding, and message protection - research_runs: split the synthesis evidence budget evenly across notes so a small context still keeps a slice of every research step instead of dropping the later steps after the earliest ones fill the budget. - research_runs: shield the research question and approved plan before placing them in the decision and synthesis prompts, so a closing delimiter in either cannot escape its block and inject sibling sections. - research_runs: redact bearer authorization tokens from public search queries. - studio_db: include attachments in the research-message change check and guard direct attachment deletion, so server-managed research prompts and responses cannot be mutated through the attachment paths. - chat_history: map the protected-message conflict on attachment deletion to 409. * Studio: strip invalid document citations that contain brackets The invalid-citation regex stopped at the first closing bracket, so a citation whose filename contained brackets left its tail (".pdf, p. 9]") in the report. Match a balanced bracketed span so the whole invalid citation is removed; valid citations stay protected by the earlier tokenization pass. * Studio: free the RAG search slot when a lookup times out or is cancelled The bounded knowledge-base search held the sole admission slot in a detached worker until the search returned, so a lookup that outlived its timeout (a stalled embedding or blocked vector call) kept the slot forever and starved every later lookup, disabling knowledge-base retrieval globally. Release the slot from the caller when it stops waiting, exactly once, so a detached worker finishes without re-holding it. * Studio: remove Websites label from research composer * Studio: fix Deep Research review findings (RAG slot bound, orphaned workers, hardening) - Bound the shared RAG search slot to one running worker. The search that is doing the embedding/index/GPU work now owns the admission slot until it finishes, instead of freeing it on caller timeout while the detached worker keeps running, which let a second search enter and stack concurrent work behind the capacity-of-one semaphore. - Cancel active research runs before deleting their thread, project, or all history. Deleting cascade-drops the run row, but the worker only notices at its next lease check, so it could keep doing model/web/RAG work for a run that no longer exists; signalling cancel first shortens that window. - Shield the planner prompt's conversation and question with _shield_untrusted, matching the decision and synthesis prompts, so untrusted text cannot forge planner delimiters. - Do not let a research key-revocation failure replace a successful non-streaming completion; log it like the streaming path does. - Include created_at in the protected research-message guard so a client cannot reorder server-managed prompt/response messages while leaving the body intact. - Reject non-scalar ragScope values; a nested container evades the sensitive-key scan when its inner keys are unlisted and would reach retrieval code that expects a scalar scope id. Adds regression tests for each. * [pre-commit.ci] auto fixes from pre-commit.com hooks for more information, see https://pre-commit.ci * Studio: remove research composer globe icon * Studio: use Hugeicons telescope in research composer * Studio: use Telescope02 icon in research composer * Studio: standardize Deep Research telescope icons * Studio: move Deep Research below web and code tools * Studio: merge grounded page excerpts with search snippets instead of replacing When auto-scrape grounding retrieved page-body chunks, it replaced the raw search-result text for that step. If the retrieved chunk was a distractor or dropped the key fact, the answer-bearing search snippet was lost and grounded runs regressed below snippet-only accuracy on factual questions (e.g. returning Apache 2.0 instead of the Qwen License, 403 instead of 404, or a single mirror diameter instead of the sum). Keep the search snippets and append the grounded excerpts as supplementary evidence via a small _merge_scraped_evidence helper.

The candidate was built from the HSA dir, so a host with libhsa-runtime64 under lib64 probed /lib64/llvm/lib. ROCm installs LLVM under /lib/llvm regardless, so that host kept binding system libamd_comgr to the bundle's libLLVM: exactly the bug #7446 reports. Probe both spellings, the HSA dir's own first so a genuine lib64 layout still wins. When lib_sub is already "lib" the seen set collapses them. 2. os.path.exists accepted a non-directory. The serve-time caller joins these straight into LD_LIBRARY_PATH with no is-dir filter, so a file named llvm/lib reached the loader. os.path.isdir instead. Verified on a 27-case matrix built from real directory trees (not mocks), run on both Windows and Linux against three revisions: main, this PR as-is, and this commit. Zero regressions and zero reorderings of the pre-existing entries in every case, and the installer and launcher copies never disagree. The lib64 case goes [lib64] -> [lib64, lib/llvm/lib]; the file case drops the bogus entry; a symlinked llvm/lib resolves correctly on Linux. End-to-end loader check: built real ELF objects mirroring the shipped bundle (RUNPATH=$ORIGIN, an incomplete libLLVM.so.23.0git next to llama-server, system comgr from /opt/rocm/lib) and reproduced the reported failure verbatim, then confirmed the prepend clears it: before undefined symbol: LLVMInitializeSPIRVTarget -> after exit 0 Test helper now patches os.path.isdir alongside os.path.exists, else every fake host reports its nested llvm dir as missing. New cases: lib64 finding llvm under lib, lib64 preferring its own when both exist, and a real-filesystem check that a non-directory is not prepended. Removing the lib fallback from one copy reddens three tests including the two-copy parity guard. tests/studio/install: 1361 passed on Linux, 4 pre-existing environmental failures unchanged (3 managed-node-runtime under root, 1 the real /opt/rocm case already covered by #7397). 30/30 on the helper suite on Windows and Linux. * [pre-commit.ci] auto fixes from pre-commit.com hooks for more information, see https://pre-commit.ci --------- Co-authored-by: Daniel Han Co-authored-by: pre-commit-ci[bot] <66853113+pre-commit-ci[bot]@users.noreply.github.com> --- studio/backend/core/inference/llama_cpp.py | 9 +++ studio/install_llama_prebuilt.py | 9 +++ .../test_rocm_native_linux_lib_dirs.py | 79 ++++++++++++++++++- 3 files changed, 96 insertions(+), 1 deletion(-) diff --git a/studio/backend/core/inference/llama_cpp.py b/studio/backend/core/inference/llama_cpp.py index 47e46405be..f76afce9f4 100644 --- a/studio/backend/core/inference/llama_cpp.py +++ b/studio/backend/core/inference/llama_cpp.py @@ -309,6 +309,15 @@ def _native_linux_system_rocm_lib_dirs(binary_dir: str = "") -> "list[str]": os.path.join(d, "libhsa-runtime64.so.1") ): out.append(d) + # ROCm keeps LLVM's versioned runtime under /lib/llvm, so a + # lib64 host still finds it under lib.

One generation made 808 highlight() calls and tokenized 5.5MB of text to render a 13.5KB block, putting ~50% of the renderer main thread in the TextMate tokenizer. Blocks under 2000 chars are unchanged. Above that, a growing fence reuses the tokens from the last real tokenization and appends the new tail unstyled, with a full re-tokenize at most every 250ms. * fix(studio): render the streamed tail unstyled and always converge Two defects found while property-testing the reuse path: - plainLine() spread the template token, so newly streamed lines inherited the first token's colour instead of the default foreground. Emit a bare token. - A reused result could be the final one if the caller stopped re-rendering, leaving the tail permanently unstyled. Schedule a trailing re-tokenize so a reused run always converges. * fix(studio): key the highlight cache per fence and keep tokens paired with code Review found four real defects in the previous approach: - entry.code advanced at dispatch time while entry.result still held the older tokens, so a reuse could slice one against the other and drop text from the cached run's final line. - A finished fence re-rendered with identical code re-dispatched every frame, keeping the per-frame cost for the rest of the stream. - All fences of one language shared a single entry, so sibling fences evicted each other and both were fully tokenized on every render. - An overdue trailing timer could dispatch stale code after a newer dispatch. Cache is now one slot per fence, matched by longest prefix. code and result only ever move together, an exact match is served straight from cache, and a direct dispatch or a slot eviction cancels any pending trailing refresh. * Studio: adopt synchronous highlight results and use a monotonic throttle @streamdown/code answers out of its own cache synchronously and never invokes the callback in that case. dispatch() ignored that return value, so the slot kept pointing at the older tokens. On the trailing refresh, where nothing else consumes the return, that left the fence showing its unstyled tail until an unrelated remount. Adopt the synchronous result on both paths and hand it to the pending callback. Drive the throttle off performance.now(). Date.now() is wall clock, so a backward step from an NTP correction or a resume from sleep makes elapsed negative, which pins the reuse branch on and schedules the trailing refresh by the size of the step. * Tighten code-plugin comments --------- Co-authored-by: shimmyshimmer Co-authored-by: danielhanchen --- .../components/assistant-ui/code-plugin.ts | 143 +++++++++++++++++- 1 file changed, 137 insertions(+), 6 deletions(-) diff --git a/studio/frontend/src/components/assistant-ui/code-plugin.ts b/studio/frontend/src/components/assistant-ui/code-plugin.ts index 1e70871c06..b6ec8d2664 100644 --- a/studio/frontend/src/components/assistant-ui/code-plugin.ts +++ b/studio/frontend/src/components/assistant-ui/code-plugin.ts @@ -47,20 +47,151 @@ const normalizeLanguage = (language: string): BundledLanguage => { return (override ??

Running them surfaced two that were broken on platforms CI never exercised: - non_utf8_import_name_preserves_csv_extension built a filename containing a raw 0xFF byte. Linux stores that fine, macOS enforces UTF-8 on APFS/HFS+ and refuses to create it, so the test panicked on the unwrap. Skip when the filesystem rejects the name; the branch under test is only reachable where such a file can exist. - losing_a_studio_package_changes_the_fingerprint created the posix venv layout unconditionally, but site_packages_dirs() only walks lib//site-packages on unix and looks at Lib/site-packages on Windows. The dist-info was therefore invisible to the fingerprint there, removing it changed nothing and the assert_ne could never hold. Build the layout the code actually reads for the target platform.

bind get_ptr and the five 4bit ctypes handles to a stub that raises a clear message if a 4bit path is entered. HAS_CUDA_STREAM stays False, which is the correct route. - save.py, models/granite.py: guard Bnb_Linear4bit and peft's Linear4bit (peft exports it only when bnb imported cleanly) with placeholder classes. Both names only feed isinstance checks, so nothing matching is exact. - _gpu_init.py: same degradation on the xpu branch as the cuda branch above. Verified on a Strix Halo (gfx1151, DEVICE_TYPE=hip, torch 2.11.0+rocm7.13.0) by blocking bitsandbytes with sys.modules["bitsandbytes"] = None, so find_spec returns None and the import raises exactly as when the package is absent. Before: ModuleNotFoundError at kernels/utils.py:136. After: import succeeds, FastLanguageModel/FastModel import, ALLOW_BITSANDBYTES=False, ALLOW_PREQUANTIZED=False, and the 4bit stub raises with the real cause. With bitsandbytes present, every binding is unchanged. New test walks the `import unsloth` module graph with ast and fails on any unguarded bitsandbytes (or peft Linear4bit) import; verified it catches the old code. Targeted suites: 702 passed, 18 skipped. * [pre-commit.ci] auto fixes from pre-commit.com hooks for more information, see https://pre-commit.ci * Address the review on #7502: zoo coupling, non-hip flags, py3.9 collection Three findings, each reproduced first and negative-controlled after. 1. The fix still needed an unreleased unsloth_zoo (P1). save.py imported unsloth_zoo.saving_utils at module scope, and any zoo without the companion #953 fix imports bitsandbytes there, so `import unsloth` kept failing for a dependency set pyproject.toml allows. Raising the floor was not an option: PyPI's newest zoo is 2026.7.6 and #953 is merged but unreleased, so a bump would break every install today. Both names it pulled in are used only inside functions, so the import is now lazy at those two call sites, matching what determine_base_model_source in the same file already does. Verified against a real pre-#953 zoo checkout with bitsandbytes blocked: import succeeds, and restoring the eager import reproduces the failure at saving_utils.py:70. This PR no longer depends on a zoo release. 2. Capability flags were only cleared on hip (P2). device_type.py probed bitsandbytes inside its DEVICE_TYPE == "hip" branch, so a cuda or xpu host without bnb imported fine but still reported ALLOW_BITSANDBYTES=True, and the default load_in_4bit=True path in models/loader.py would select a 4bit checkpoint before failing. Clear both flags whenever the module is absent, on every backend, via find_spec so a working install pays nothing. A cuda host with bnb blocked now reports False/False; with bnb present nothing changes. 3. The new test could not be collected on Python 3.9 (P2). `Path | None` is a PEP 604 union and requires-python still allows 3.9, so pytest raised TypeError at import. Added `from __future__ import annotations`. Checked in real uv venvs on 3.9, 3.10 and 3.13: 2 passed each; removing the future import reproduces "unsupported operand type(s) for |" on 3.9 only. The xpu branch in _gpu_init.py needs no separate flag handling now that the probe is backend-independent. * [pre-commit.ci] auto fixes from pre-commit.com hooks for more information, see https://pre-commit.ci * Address the second review on #7502: guarded probe, and 8bit in the same guard 1. The capability probe used find_spec while the fallbacks in kernels/utils.py and _gpu_init.py treat any import failure as unavailable, so an installed but unusable wheel would leave ALLOW_BITSANDBYTES true while the kernels had already bound the stub. Probe with the same guarded import instead, so all three agree by construction. No new cost on any path: _gpu_init.py already imports bnb before device_type is reached on cuda, and device_type's own hip block imports it a few lines later. Worth recording that the state this prevents is currently unreachable for an unrelated reason: a broken wheel takes `import unsloth` down earlier, in transformers/integrations/bitsandbytes.py:20 via unsloth_zoo/patching_utils.py:680, whichever exception it raises (OSError also escapes the zoo moe_utils `except ImportError`). So this is correctness for when those imports get guarded, not an observable fix today. 2. Both loader guards printed for load_in_4bit or load_in_8bit but only cleared load_in_4bit, so an explicit load_in_8bit=True survived and reached Transformers, which builds the bnb quantizer and fails there. Clear both. The message no longer says AMD either: the flag now goes false whenever bnb is unusable on any backend. Tests: the probe must not use find_spec, and an ast walk requires every ALLOW_BITSANDBYTES guard in loader.py to clear both flags, so a third guard cannot be added with the same omission. Dropping either fix reddens them (1 and 2 failures respectively). 4 passed on 3.9, 3.13 and the ROCm venv; absent and healthy bnb both stay consistent across hip and cuda. * [pre-commit.ci] auto fixes from pre-commit.com hooks for more information, see https://pre-commit.ci * Drop the importlib import left over from the find_spec probe on #7502 * Address the third review on #7502: exact-name bypass and a forwarded bnb config Both findings hold up, so both are fixed. 1. use_exact_model_name=True skipped the guard entirely. load_in_4bit defaults to True, so on a host without bitsandbytes FastLanguageModel.from_pretrained(name, use_exact_model_name=True) kept 4bit set and failed downstream. That option suppresses repo-name remapping and cannot make bitsandbytes available, so it has no business gating a capability check. Ungated at both sites. 2. A user-supplied quantization_config survived the fallback. It sets load_in_4bit/8bit at the top of from_pretrained and stays in kwargs, so clearing the local flags still let Transformers rebuild the bnb quantizer. Now dropped as part of the fallback. One correction to the second suggestion: it cannot be dropped whenever the fallback runs. quantization_config also carries GPTQ, AWQ, fp8 and torchao configs, which have nothing to do with bitsandbytes and must reach the loader untouched. The pop is gated on the config actually requesting load_in_4bit or load_in_8bit, reusing the same dict/attr probe from the top of the function. Behaviour, exercising the real guard block against synthetic inputs with use_exact_model_name=True and bnb unusable: default 4bit, no cfg 4bit=False 8bit=False explicit 8bit, no cfg 4bit=False 8bit=False BitsAndBytesConfig(4bit/8bit) 4bit=False 8bit=False config dropped dict bnb config 4bit=False 8bit=False config dropped GPTQ config 4bit=False 8bit=False config SURVIVES fp8 dict 4bit=False 8bit=False config SURVIVES Nothing changes when bitsandbytes works: the whole block is inside `if not ALLOW_BITSANDBYTES`. Tests: an ast walk requires neither guard to reference use_exact_model_name in its test, and requires each to pop quantization_config behind a _wants_bnb check, so an unconditional pop fails too. Re-gating one guard or removing one pop reddens a test each. 6 passed on 3.9, 3.13 and the ROCm venv. * [pre-commit.ci] auto fixes from pre-commit.com hooks for more information, see https://pre-commit.ci * Address the fourth review on #7502: FastModel never reached the 16bit path Both findings are real, and the second one meant this PR did not actually deliver what it advertises for FastModel or vision loads. Reproduced first. 1. patch_compiling_bitsandbytes() ran unguarded at the top of FastModel.from_pretrained, and unsloth_zoo's copy imports bitsandbytes unconditionally (patching_utils.py:40). So every FastModel call on a bnb-less host died there, whatever the arguments: FastModel(load_in_16bit=True) -> ModuleNotFoundError at patching_utils.py:40 FastModel(full_finetuning=True) -> ModuleNotFoundError at patching_utils.py:40 The FastLanguageModel path already wraps this call in try/except with a warning, and its comment even says "Mirror FastModel" - FastModel was the unwrapped one. Wrapped it the same way, so behaviour is unchanged wherever bitsandbytes imports. 2. The mode-exclusivity check ran before the capability fallback. load_in_4bit defaults to True, so load_in_16bit=True made int(load_in_4bit) + int(load_in_16bit) == 2 and raised "Can only load in 4bit or 8bit or 16bit" before the fallback could clear the unavailable 4bit request. Moved the fallback ahead of that check. After both, the same three calls get past every bitsandbytes gate and reach model resolution, failing only on the deliberately fake repo name used by the probe. Nothing changes when bitsandbytes works: the fallback is still inside `if not ALLOW_BITSANDBYTES`, and the wrapper only swallows an import that previously crashed the load. Tests: the mode check must be preceded by an ALLOW_BITSANDBYTES fallback in the same function, and no call to patch_compiling_bitsandbytes may sit outside a try. The ordering assertion is scoped to the enclosing function on purpose - my first version compared line numbers file-wide, so the other loader's guard satisfied it and the negative control passed when it should have failed. With the scoping fixed, moving the fallback back after the mode check reddens it, as does unwrapping the patch call. 8 passed on 3.9, 3.13 and the ROCm venv. * [pre-commit.ci] auto fixes from pre-commit.com hooks for more information, see https://pre-commit.ci --------- Co-authored-by: pre-commit-ci[bot] <66853113+pre-commit-ci[bot]@users.noreply.github.com> --- .../test_import_without_bitsandbytes.py | 296 ++++++++++++++++++ unsloth/_gpu_init.py | 10 +- unsloth/device_type.py | 11 + unsloth/kernels/utils.py | 54 +++- unsloth/models/granite.py | 16 +- unsloth/models/loader.py | 92 +++++- unsloth/save.py | 27 +- 7 files changed, 468 insertions(+), 38 deletions(-) create mode 100644 tests/python/test_import_without_bitsandbytes.py diff --git a/tests/python/test_import_without_bitsandbytes.py b/tests/python/test_import_without_bitsandbytes.py new file mode 100644 index 0000000000..bd19ed651f --- /dev/null +++ b/tests/python/test_import_without_bitsandbytes.py @@ -0,0 +1,296 @@ +"""`import unsloth` must survive a missing bitsandbytes. + +device_type.py already tells the user "bitsandbytes is not installed - 4bit QLoRA +unallowed, but 16bit and full finetuning works", and the gfx906 install path +(#7354) deliberately removes the generic wheel because it carries no gfx906 +kernels.

It is unbounded, though, and the thing it is unbounded against is not the GPU. A run stopped on an approval prompt is blocked inside the to_thread(next, gen) call that drives it, so it holds one of asyncio's default min(32, cpu + 4) executor threads until the user answers. The slot cap used to bound that. Parking hands the slot back, which admits another run that can park too, so the ceiling became the wait line: 64 deep on a 1-slot backend. Long before that, the executor is full and nothing else in the backend runs, including generation steps for chats that already hold slots and the stream teardown that would clean up after a disconnect. The pool already permits `capacity` pending prompts, and each park adds one more, so the budget is what the executor has left after the cap and a reserve of 4. On this machine (32 workers) --parallel 4 gets 8 parks and 20 free threads, --parallel 24 gets 4 and 4, and --parallel 28 or higher gets none: there the prompt keeps its slot and behaves exactly as it did before parking existed. Counted process-wide rather than per queue. There is one executor, but a per-queue budget is the same allowance again for every backend, and base_url carries a fresh port on every model load, so a reload would mint a queue that knows nothing about the approvals still parked on the old one. A reset clears it too, or a leaked claim shrinks the budget for the life of the process. park() reports whether it took the budget, and a refusal costs nothing to undo because the slot never left its holder. The stream reads that answer rather than recording a refused park as parked, which would make it skip the park for every later approval in the same run even once the budget freed up. * [pre-commit.ci] auto fixes from pre-commit.com hooks for more information, see https://pre-commit.ci * Size the park budget from the executor's own CPU count Two review findings, both real. The budget read os.cpu_count(). 3.13 sizes ThreadPoolExecutor from os.process_cpu_count(), which honours CPU affinity and cgroup quotas, and asyncio's default executor is a plain ThreadPoolExecutor(), so a container pinned to one core on a 64-core host got a 5-thread executor and a budget computed from 64. The bound was then looser than no bound at all in exactly the environment that can least afford it. It asks the same source the executor does, and the test compares against a real ThreadPoolExecutor rather than restating the formula, so it stays right on 3.12 as well. The reserve was a flat 4, which on that same 5-thread executor left nothing to budget and turned parking off entirely. Small hosts are where a chat most needs to keep moving while another sits on a prompt. It scales now, and the ceiling has a floor of two: a quarter of five is one, and one park cannot cover two chats on prompts at once, which is what #7455's own two-approvals test needs. Without that floor, that test fails on a one or two CPU runner. `spare` still takes the budget to zero when the pool already fills the executor, so nothing about a 32-worker machine changes: --parallel 4 still gets 8 parks, 24 gets 4, 28 gets none. The two behavioural budget tests pin the worker count rather than reading it off the runner, and the property test sweeps executor sizes from one CPU to 64 instead of asserting against whatever the host happens to have. The whole suite passes with the CPU count faked to 1, 2 and 4, which is how both of these were reproduced. * [pre-commit.ci] auto fixes from pre-commit.com hooks for more information, see https://pre-commit.ci * Size the park budget from every live backend, and free it on the answer Two review findings, both real. The budget was global but sized from one queue's capacity. A reload mints a queue on a new port while the old one drains, so both are live, and prompts on both park executor threads. Eight parks on an old 1-slot queue plus a new 24-slot backend is 32 threads on a 32-thread executor, with the new backend's prompts refused and holding their slots, which is the state the reserve exists to prevent. It sums the capacity of every backend still serving instead. Idle queues are skipped: those are the ones the registry is about to evict, and they are holding nothing. The budget also outlived the wait it was paying for. unpark_async only dropped it after reacquiring a slot, but the generator yields its post-approval event first, so the executor thread is already back in the pool while the resume queues. An approved chat waiting on a slot would refuse a different chat's park, and that chat then keeps the slot the resumer is waiting for, so an unanswered prompt strands chats that were already approved. The budget is released when the prompt wait ends now, and the queue's parked count still runs until the slot is back, which is what guards idle eviction and the resume ordering. Both are separate counters on the lease as a result, and every exit from a park drops the budget: unpark, unpark_async and release. That last one was the mutant that came back missed, since a client disconnecting on a prompt releases straight out of parked and would otherwise lose a budget slot for good. * [pre-commit.ci] auto fixes from pre-commit.com hooks for more information, see https://pre-commit.ci * Tighten the comments on the park budget --------- Co-authored-by: pre-commit-ci[bot] <66853113+pre-commit-ci[bot]@users.noreply.github.com> --- .../backend/core/inference/llama_admission.py | 133 ++++++++++- studio/backend/routes/inference.py | 5 +- studio/backend/tests/test_llama_admission.py | 226 ++++++++++++++++++ 3 files changed, 355 insertions(+), 9 deletions(-) diff --git a/studio/backend/core/inference/llama_admission.py b/studio/backend/core/inference/llama_admission.py index db9a5d8ce4..7bf0dd7429 100644 --- a/studio/backend/core/inference/llama_admission.py +++ b/studio/backend/core/inference/llama_admission.py @@ -58,6 +58,80 @@ DEFAULT_ADMISSION_QUEUE_PER_SLOT = 16 DEFAULT_ADMISSION_MIN_QUEUE = 64 +def _executor_workers() -> int: + """Threads asyncio's default executor runs to_thread work on. + + Mirrors ThreadPoolExecutor's own default sizing, which is what + ``run_in_executor(None, ...)`` builds. 3.13 sizes it from + ``process_cpu_count()``, which honours CPU affinity and cgroup quotas; + ``cpu_count()`` would budget from the whole host inside a one-core container. + """ + cpus = getattr(os, "process_cpu_count", os.cpu_count)() or 1 + return min(32, cpus + 4) + + +def _executor_reserve(workers: int) -> int: + """Threads kept clear of parked approvals, for generation steps, stream + teardown and unrelated to_thread work.

Every other failure path in studio/setup.ps1 goes through Exit-SetupFailure, and tests/sh/test_tauri_retry_failure_context.sh asserts that invariant, so 'Repo tests (CPU)' has been red on main since that merge.

The latter can be "hip" or "mlx", which .to() rejects, so this regressed ROCm. - test_batched_leftpad_generation_gpu.py: XPU diverges here today, so mark it non-strict xfail on XPU instead of reverting to a CUDA-only guard. Keeps the real XPU gap visible and turns green once it is fixed. - Guard torch.xpu.is_available() with hasattr, matching device_type.py. * [pre-commit.ci] auto fixes from pre-commit.com hooks for more information, see https://pre-commit.ci * Re-enable the flash varlen attention test in CI for PR #7401 attention_dispatch.py now predefines flash_attn_func / flash_attn_varlen_func as None, so test_run_attention_flash_varlen_receives_window_and_softcap no longer needs flash_attn importable to be monkeypatched. Verified on a runner shaped like the CPU-only one: the test fails against main's attention_dispatch and passes at this head, so the deselect is now dead weight. * Tighten comments for PR #7401 Drop the hasattr rationale: torch.xpu has existed since torch 2.3 and the dependency floor is 2.4, so no supported build predates the namespace. The guard stays as cheap defence, but the comment claimed something untrue. --------- Co-authored-by: pre-commit-ci[bot] <66853113+pre-commit-ci[bot]@users.noreply.github.com> Co-authored-by: danielhanchen --- .github/workflows/consolidated-tests-ci.yml | 10 +++--- .../test_merge_model_perplexity_llama-3.2.py | 11 +++---- .../test_merge_model_perplexity_mistral.py | 11 +++---- .../test_merge_model_perplexity_phi_4.py | 11 +++---- ...st_merged_model_perplexity_llama-3.1-8b.py | 11 +++---- .../test_merged_model_perplexity_qwen_2.5.py | 13 +++----- tests/test_fp8_tiny_e8m0.py | 10 +++--- tests/utils/perplexity_eval.py | 5 ++- .../test_batched_leftpad_generation_gpu.py | 17 ++++++++-- tests/utils/test_packing.py | 20 +++++++++--- tests/utils/test_qat.py | 8 ++++- tests/utils/test_rope_scaling_drift.py | 32 ++++++++++--------- unsloth/utils/attention_dispatch.py | 2 ++ 13 files changed, 94 insertions(+), 67 deletions(-) diff --git a/.github/workflows/consolidated-tests-ci.yml b/.github/workflows/consolidated-tests-ci.yml index 489ee4ca08..c75880fa72 100644 --- a/.github/workflows/consolidated-tests-ci.yml +++ b/.github/workflows/consolidated-tests-ci.yml @@ -372,12 +372,10 @@ jobs: tests/python/test_fast_language_model_text_only.py \ tests/test_bad_mappings_redirect.py \ tests/test_prefetch_snapshot_scope.py \ - tests/test_gemma_2b_mapper_key.py \ - --deselect 'tests/utils/test_attention_masks.py::test_run_attention_flash_varlen_receives_window_and_softcap' - # The deselected test monkeypatches flash_attn_varlen_func, which is - # only bound on the module when `flash_attn` is importable. flash_attn - # requires CUDA + dev toolchain, which the CPU-only ubuntu-latest - # runner does not have.

Replace them with two tests that drive get_model_name end to end: one splices an FP8 entry into the fetched source only and asserts the upgrade error still fires, the other serves a mapper.py with no FP8 tables and asserts the 4bit half of the probe survives, which is the regression #7497 fixed. * [pre-commit.ci] auto fixes from pre-commit.com hooks for more information, see https://pre-commit.ci * Tighten the resolver stub for PR #7516 - Restore the fp8_block/fp8_row identity assert alongside the new provenance test. It is weak, not vacuous: it still catches a probe that hands back the installed table objects, and it costs nothing to keep. - Bind Version and transformers_version in the stub namespace. Both are unreached under the current gates, so a change to either would fail with a bare NameError instead of the assertion. Merged main, which clears the unrelated test_runtime_text_encoding failure the branch inherited from its base. * Cover the FP8 row-scaling path instead of duplicating the block one The two tests this PR originally added were already covered by tests/test_new_mapper_fetched_fp8.py from #7497. An 8-mutant matrix over loader_utils.py found nothing they caught that the existing file did not, so they are dropped and test_new_mapper_no_global_leak.py goes back to main. Two real gaps were open, both on the row branch that load_in_fp8 = True plus UNSLOTH_HAS_FBGEMM selects ahead of block: - the FBGEMM row branch in __get_model_name could be deleted outright with every test still green - _resolve_with_mappers could ignore its fp8_row argument and silently fall back to the installed row table Adds two tests to the existing file, reusing its _load_resolver rather than a second harness. The row-only fixture splices into the fetched row table alone, since an entry the block table also knows lets the block branch answer and masks the regression. * [pre-commit.ci] auto fixes from pre-commit.com hooks for more information, see https://pre-commit.ci --------- Co-authored-by: pre-commit-ci[bot] <66853113+pre-commit-ci[bot]@users.noreply.github.com> Co-authored-by: danielhanchen --- tests/test_new_mapper_fetched_fp8.py | 53 ++++++++++++++++++++++++++++ 1 file changed, 53 insertions(+) diff --git a/tests/test_new_mapper_fetched_fp8.py b/tests/test_new_mapper_fetched_fp8.py index 2835aadb59..bdd1b241fa 100644 --- a/tests/test_new_mapper_fetched_fp8.py +++ b/tests/test_new_mapper_fetched_fp8.py @@ -14,6 +14,11 @@ Two gaps it misses: future rename): reading them with ``[]`` raises ``KeyError`` into the bare ``except``, taking the 4bit half, the probe's whole purpose, down with it. +Both of the above only reach the block table.

Promote the bounds into this dependency-free module, which already owns the -np/--parallel semantics, and record the deliberate mirrors that cannot import it (run.py, the unsloth CLI, the web UI). The denylist entry stays: the first-class field is now the single write path for the slot count, so a pass-through would still desync the committed bookkeeping from llama-server. * feat(studio): note the per-load override in the --parallel help text --parallel is now the server-wide default that a per-load n_parallel (the Studio Parallel Slots run setting) can override, not the definitive slot count. Point at the new control so a user does not conclude a restart is the only way to change slots, and record the shared PARALLEL_MIN/MAX mirror alongside the existing CLI one. * feat(studio): add n_parallel to LoadRequest and echo the slot counts LoadRequest.n_parallel (optional, PARALLEL_MIN..PARALLEL_MAX) lets a load pick its own llama-server --parallel count; omitted, the server-wide launch default applies. ValidateModelRequest carries it too so the training-coexistence estimate sizes the KV cache like the follow-up load rather than passing on a smaller footprint. LoadResponse and InferenceStatusResponse gain both requested_parallel_slots (what the load was invoked with) and parallel_slots (what llama-server actually runs after the fitter's slot reduction), so a client can tell an honored request from a reduced one. Both are None where --parallel has no meaning: non-GGUF loads and the diffusion runner. * feat(studio): record the requested parallel-slot count on the backend The auto GPU-memory fit may launch fewer slots than requested to keep the model fully on GPU, so the committed effective count cannot answer "is the live server what this request asked for?". Store the invoked count separately (mirroring the _requested_n_ctx pattern) from the pre-reduction pending kwargs, expose it as requested_parallel_slots, and have _already_in_target_state compare requested-vs-requested: comparing against the effective count would reload -- and re-reduce -- forever on an identical Apply. The comparison sits in the non-diffusion branch, since the diffusion runner ignores --parallel entirely. The requested value shares the effective count's lifecycle, so every unload/kill path clears it and a stale count cannot poison the next load's dedupe. * feat(studio): honor a per-load parallel-slot count in /load and /validate Resolve the slot count once per load -- the request field if set, else the server-wide launch default -- and feed it to every consumer that must agree: the training-coexistence guard, the llama-server load kwargs, and the reload dedupe. Without the dedupe comparison a changed slot count would be swallowed as already_loaded; it compares requested-vs-requested and skips the diffusion runner, which ignores --parallel. app.state.llama_parallel_slots is deliberately never written: it stays the launch intent and the admission-queue fallback, so one load's override cannot leak into later loads. /validate resolves the same way so its estimate cannot undercount what the load then allocates. Both /load returns and /status echo the counts through one helper, which reports None for diffusion -- its load never commits a count, so echoing the reset placeholder would fabricate an "invoked with 1 slot". * feat(studio): accept nParallel in the chat-preset load config ChatPresetLoadConfig is extra="forbid", so a preset carrying the new parallel slots knob would 422 the whole settings sync without this field. Bounds come from the shared PARALLEL_MIN/MAX rather than literals, so a future range change cannot start rejecting presets the UI still allows. * test(studio): cover the per-load parallel-slots knob Pins the behaviors a regression would silently break: the requested-vs-effective dedupe (comparing against the reduced count would reload forever), the diffusion skip and its None echo, the requested count's reset lifecycle, and its commit from the pre-reduction pending kwargs. Also pins the three bounds mirrors that cannot import PARALLEL_MIN/MAX (run.py, the unsloth CLI, the web UI) plus the preset model that can, so a range change cannot leave one of them clamping or rejecting at the old limit. * test(studio): refresh the --parallel denylist comments for the UI knob The pinned rationale said the typer flag owns the slot count and pointed users at a Studio restart. Parallel Slots / LoadRequest.n_parallel is now the other managed writer, and the 1..64 guard is the shared PARALLEL_MIN/MAX -- a reader following the old comments would conclude the UI control does not exist. * feat(studio): note the per-load override in the CLI --parallel help Both the plain-serve and `unsloth studio run` flags now describe a server-wide default the Studio Parallel Slots run setting can override per load, matching the backend help text. * feat(studio): remember a per-model Parallel Slots override nParallel joins the per-model config with the same null-means-follow-the-default convention as the other knobs: null keeps the server-wide --parallel count, so a blank control never pins a number and isDefaultConfig still deletes an otherwise-untouched config instead of storing it. The value is re-clamped to N_PARALLEL_MIN/MAX on every localStorage read and write (the store is user-editable), and listing it in STORED_CONFIG_FIELDS keeps it from being dropped as an unknown key. Legacy blobs predate the knob, so their migration carries null. No schema-version bump: an additive optional field, like the GPU fields before it. * feat(studio): bridge nParallel between the per-model config and the store The config->store, store->config and equality helpers all need the new field: without the equality arm a slots-only edit reads as unchanged, so Apply is dropped and the dirty state never lights up. * feat(studio): track the parallel-slot override in the chat runtime store nParallel holds the editable override and loadedNParallel the value the last successful load sent, which the failed-switch rollback re-sends. Both are per-model: they clear on unload and on a model switch, unlike the standing preferences (GPU memory mode, speculative type) that survive one. There is deliberately no backend-echo field for the control: the echo is the resolved count, so adopting it would pin a blank "follow the server default" input to an explicit number. * feat(studio): type n_parallel and the slot-count echoes The load request gains the optional per-load slot count, and both the load response and the status payload gain requested_parallel_slots (invoked) and parallel_slots (actually running after the fitter's reduction). Keys stay snake_case: the payload is serialized as-is, with no case conversion. * feat(studio): forward n_parallel to the validate preflight validateModel builds its own body rather than forwarding the load payload, so the slot count has to be listed explicitly. Slots scale the KV estimate, and the preflight exists to refuse a load the training guard would then 409 -- an unforwarded count would validate a smaller footprint than the load allocates. * feat(studio): include nParallel in the active model's config The sidebar assembles the active model's config from individually subscribed store fields; an unsubscribed field would leave the form showing a stale value after any external change. * feat(studio): add the Parallel Slots control to the run settings A numeric input in the GGUF advanced section, blank meaning "follow the server default". It clamps on change like the Draft Tokens field rather than using NumericValueInput, so there is no blur-draft to lose when the user types a value and immediately clicks Load. hasNonDefaultAdvanced counts it too, so a remembered override reopens the advanced section instead of hiding the setting that is actually in effect. * feat(studio): key the sidebar config form on nParallel too The signature drives the remount that re-seeds the form; without the new field an externally changed slot count would leave the sidebar showing the old one. * feat(studio): send the Parallel Slots override on load performLoad snapshots the slot count at click time (staged run-settings config first, else the store) and sends it on both the validate preflight and the load, so the two size the same footprint. A cross-model switch re-baselines it like the other per-model knobs -- the previous model's count must not follow onto the next one -- and the failed-switch rollback re-sends the previous model's value so a rescue reload cannot silently drop to the server default. The success path keeps the click-time value rather than the response echo: the echo is the count the fitter resolved, so adopting it would turn a blank "follow the server default" control into an explicit pin. Slots are GGUF-only, so a transformers load sends and records null instead of a phantom override. * feat(studio): carry the slot override through the compare-pane load The compare pane builds its own load request, so it needs the field explicitly or a pane with a remembered override would load at the server default. Its validate preflight sends the same count, matching the comment above it that promises validation is sized exactly as the load below. GGUF-gated on both calls, and the store adopts the pane's own click-time value rather than the resolved echo, mirroring the single-model path. * feat(studio): honor the remembered slot override on startup auto-load The auto-load path reads the per-model config and forwards every other remembered knob, so a remembered Parallel Slots value was the one setting lost on the "load last used model" path: llama-server came back at the server-wide default with the control showing blank, and the first manual Apply afterwards then forced a needless reload because the counts disagreed. * feat(studio): seed the slot baseline from the status echo Only the rollback baseline is seeded, never the editable control: the echo is the resolved count, so adopting it would pin a blank "follow the server default" input to a number. Without the seed, loadedNParallel stayed null after a tab reload or a second tab adopting the running model, and a failed switch then rolled the previous model back at the server default while every other knob was restored. * feat(studio): capture Parallel Slots in chat presets The knob joins the preset load config end to end: captured from the store, re-clamped when read back (persisted presets are untrusted input), applied on switch, and summarized in the preset chip. Its default is null, so coalesceDefaultLoadKnobs keeps a default-only preset empty rather than persisting a no-op override. * feat(studio): re-derive the preset state when Parallel Slots changes Both preset memos snapshot the store through capturePresetLoadConfig, so without the new dependency a slots-only edit left the unsaved-changes flag and the load summary showing the previous value. * test(studio): pin the Parallel Slots wiring end to end Source-contract coverage for the hops a refactor can silently drop: the three /load builders (interactive, compare pane, startup auto-load) and their validate preflights, per-model persistence and clamping, the UI row, and the status seed -- including the negative assertion that hydration seeds only the rollback baseline, never the control, so the resolved echo cannot pin a blank "server default" input. * test(studio): pin nParallel in the preset load config Covers capture, clamped read-back and apply on the frontend, plus the backend field itself: ChatPresetLoadConfig is extra="forbid", so a missing or drifted field 422s every settings sync that carries a preset. * [pre-commit.ci] auto fixes from pre-commit.com hooks for more information, see https://pre-commit.ci * Fall back to one slot when llama-server lacks --kv-unified for PR #7447 Without --kv-unified an explicit --parallel N makes llama-server give each slot -c/N, so on a build without the flag choosing N slots silently shrinks every context window for a feature that build cannot serve. Clamp to one slot and log why, placed after the requested count is captured so the echo still reports it and before the KV estimates so the fit matches what actually launches. * [pre-commit.ci] auto fixes from pre-commit.com hooks for more information, see https://pre-commit.ci * Clear the slot control on load paths that never send it, and size the training guard for diffusion Four review findings on the per-load Parallel Slots knob. The editable nParallel control means "follow the server default" when null, so any success path that does not send a slot count has to clear it. Three paths kept a value staged for a different model: - chat-adapter.ts, cached non-GGUF auto-load: the interactive and compare builders already clear both fields for a non-GGUF response, this third one did not. The field never renders for a non-GGUF target, so the stale count was invisible and unclearable from the UI yet still persisted, and it flips isDefaultConfig so a user with no overrides silently gets a stored entry. - chat-adapter.ts, fresh-model fallback: its request omits n_parallel but its success state resynced every other knob and left the slots alone, so a staged edit survived against a server running the default and the next Apply reloaded at a count that load never sent. - apply-inference-status-to-store.ts: on a model change underneath the tab every sibling knob adopts the new model's status, but nParallel updated only its baseline, so the previous model's explicit count followed onto the new model and saving or reloading there pinned it. Clear the control and keep seeding the baseline for the rollback. The training-coexistence guard sized a diffusion GGUF with the requested slot count. _estimate_kv_cache_bytes scales the SWA cache with slots (swa_limit = swa * slots + ubatch), but load_model hands a diffusion target to _start_diffusion_server before the slot plumbing, so that runner is always single-slot. At the new default of 4 this inflated the estimate and could 409 a load that fits. An unclassified GGUF keeps the requested count. Backend base KV depends on -c alone, not on --parallel, which is why only the SWA term is affected: llama.cpp PR 14363 and discussion 4130. Tests: three training-guard cases in test_parallel_slots_per_load.py and one source contract in test_model_picker_contracts.py, each mutation-checked. 174 passed across the backend slot/admission/training suites, 56 across the frontend contract suites. * [pre-commit.ci] auto fixes from pre-commit.com hooks for more information, see https://pre-commit.ci * Keep the slot control when re-adopting the running model, and never record slots for a diffusion load Two follow-ups from the latest review round. The first is a regression from c796393. That commit cleared the slot control whenever hydratingExistingModel was set, to stop model A's count following onto model B. But that flag is also set on the resident-model adopt path: when the store checkpoint is an external provider id and the user re-picks the still loaded local model, applyActiveModelStatusToStore is called with the external id as previousCheckpoint, so the flag is unconditionally true. The clear then wiped the config applyPerModelConfigToRuntime had restored two lines earlier, and it was the only knob that did, because the siblings re-adopt the status echo while this one cleared. Gate the clear on the tab's own baseline no longer matching the running count: a genuine A to B swap still clears, re-adopting the same model keeps its value. The second revises an earlier call of mine. I rejected the diffusion phantom as cosmetic because the backend ignores the value on every send. The sharpened report is right and my rejection was wrong: capturePresetLoadConfig records nParallel with no model gate, a Preset carries no model id, and applying one writes nParallel for whatever model is current. So a count recorded against a diffusion model, which the backend never applied, rides a saved preset onto a text GGUF and becomes a real override the user never chose. Record slots only when the load actually committed them, on all three load builders. Tests: two source contracts in test_model_picker_contracts.py, both mutation checked. Frontend typecheck clean, 58 passed across the contract and preset suites. * [pre-commit.ci] auto fixes from pre-commit.com hooks for more information, see https://pre-commit.ci * Clear the slot baseline when status reports a model without slots Hydrating from a GGUF to a slotless model left loadedNParallel at the previous model's count: the seed only runs when the echo is non-null, and the control clear added earlier touches nParallel alone. The stale baseline is what a failed-switch rollback re-sends, and preset capture reads it, so it could claim slots for a model that never used them. Clear it when status describes a model that cannot have slots. /status omits the echo entirely for non-GGUF and sends an explicit null for the diffusion runner, so keying on is_gguf === false or an explicit null covers both while an absent field on a GGUF, which is how an older backend reports one, still leaves the baseline alone.

Streamdown does not revise a block it has already committed, so the panel keeps rendering the previous artifact's source. Key the source view on the artifact ID plus a hash of its code: tool artifact IDs are derived from the tool call, not the code, so the ID alone does not change when a tool artifact is updated in place. * Name the real root cause and make the source-key test load-bearing The remount is needed because Streamdown memoizes a fenced code block on its hast node's line/column span, which ignores the text inside the fence, so two canvases of equal line count compare equal and the old source stays on screen. Verified in Chromium against streamdown 2.5.0: unkeyed, 70 lines -> 70 lines renders the previous artifact, 70 -> 71 and 70 -> 90 render correctly. Move the key expression into the source branch so it costs nothing while the artifact is streaming and the view is unmounted, and export the helper from types.ts so the test exercises the shipped code instead of a local copy of the formula (it passed before even with the key removed from the component). * Assert the source view's Streamdown key wiring, not just the helper The suite exercised buildArtifactSourceKey but never the component, so deleting key={buildArtifactSourceKey(artifact)} from the Streamdown left every test green. There is no DOM renderer available to these tests, so parse artifact-surface.tsx with the TypeScript compiler API (already a devDependency) and assert the source view's Streamdown carries that key. Mutation-checked: removing the key fails 1 test, swapping it for artifact.id fails 1, and making the helper ignore code fails 2. * Tighten the comments added by this PR --- .../chat/artifacts/artifact-surface.tsx | 4 +- .../src/features/chat/artifacts/types.ts | 9 ++ .../tests/artifact-source-key.test.ts | 130 ++++++++++++++++++ 3 files changed, 142 insertions(+), 1 deletion(-) create mode 100644 studio/frontend/tests/artifact-source-key.test.ts diff --git a/studio/frontend/src/features/chat/artifacts/artifact-surface.tsx b/studio/frontend/src/features/chat/artifacts/artifact-surface.tsx index 1955c3aca1..4e28e7f457 100644 --- a/studio/frontend/src/features/chat/artifacts/artifact-surface.tsx +++ b/studio/frontend/src/features/chat/artifacts/artifact-surface.tsx @@ -30,7 +30,7 @@ import { Streamdown } from "streamdown"; import { ArtifactHtmlFrame, type ArtifactViewMode } from "./html-frame"; import { useChatArtifactsStore } from "./store"; import type { ChatArtifact } from "./types"; -import { getArtifactFilename } from "./types"; +import { buildArtifactSourceKey, getArtifactFilename } from "./types"; const COPY_RESET_MS = 2000; const artifactSourceCodePlugin = createCodePlugin({ @@ -338,6 +338,8 @@ export function ArtifactSurface({ ) : (

Nothing under either gate needs a toolchain. uv is a prebuilt binary, CPython comes from uv's managed python-build-standalone, llama.cpp and whisper.cpp are prebuilt downloads, Node is a pinned nodejs.org archive, and triton is skipped on macOS. unslothai/llama.cpp b10107-mix-1911198 publishes macos-arm64, macos-x64, linux-x64 and linux-arm64 builds covering cpu, cuda12, cuda13, rocm and vulkan. PR #6617 already dropped the Homebrew/cmake stop on macOS for this reason and just left the CLT stop behind. macOS: warn and continue when the CLT are absent. Linux: only a download transport (curl or wget) is fatal; build tooling warns. Both keep a hard git requirement for --local, which installs unsloth-zoo from a git+https URL. Both gates move into functions so tests/sh can extract them. The old inline form could not be reached by the tests/sh convention, which is why this shipped broken and stayed broken. test_macos_clt_gate.sh (19 assertions) and test_linux_deps_gate.sh (25) cover the clean machine, the CLT-stub shape where /usr/bin/git exists but fails, the non-apt distro, and the --local paths. Writing the Linux test caught a latent bug: the gate trimmed its list with $(echo ... | sed ...), so on a minimal image without sed the substitution yields empty and it reports 'all system dependencies found' on a machine with none of them. Replaced with parameter expansion. Also caps av<16 in the single-env constraints. av 16+ ships no cp313 macOS arm64 wheel, and it is a C extension over FFmpeg, so uv would silently fall back to a source build needing both a compiler and FFmpeg headers. Verified on GitHub-hosted macOS runners with /var/db/xcode_select_link, /Library/Developer/CommandLineTools, /Applications/Xcode*.app and Homebrew moved aside. macos-14, macos-15 and macos-26 fail on main and install cleanly with this; the recorded tool-invocation trace for the whole install is a single `xcode-select -p`, so nothing compiled and nothing installed a toolchain. * Linux: auto-install git rather than dropping it, and skip triton kernels without it Making git optional on Linux was too broad. studio/backend/requirements/ triton-kernels.txt line 2 is a git+https URL, so step 6/14 died with 'Cannot find command git' and failed the whole setup on ubuntu2404-root, ubuntu2404-arm-root and fedora41, all of which had been passing. The claim that nothing on the consumer path needs git holds on macOS, where triton is skipped, but not here. install.sh now auto-installs git through apt with the other optional tooling, so Debian and Ubuntu are unchanged. The triton kernels step skips with a message when git is absent instead of failing: they are a training speedup, not a boot requirement, and a GGUF chat install has no use for them. Six more assertions pin both halves. * macOS Intel: skip the one package with no x86_64 wheel The Intel clean-machine leg installed with the toolchain masked, then died in studio setup: subprocess.CalledProcessError: Command '['cmake', ...]' returned non-zero ERROR: Failed building wheel for pytorch_tokenizers pytorch_tokenizers publishes wheels for macOS arm64, linux x86_64, linux aarch64 and windows, but none for macOS x86_64 at any Python version, so uv falls back to an sdist that shells out to cmake. Nothing passes --only-binary, so the compiler-free property was an assumption rather than a contract, and Intel is where it broke. Marked so it installs everywhere except Intel macOS. Apple Silicon is unaffected. * Stop the optional dep gate from aborting the install _smart_apt_install exits rather than returns, and `|| true` does not catch an exit, so a box missing cmake or git aborted at the gate added to let it continue. Verified in sh, dash and bash. Run it in a subshell and re-raise only code 2, the NEED_SUDO handshake install.rs answers with an elevation prompt. install.sh treats a present-but-broken git as missing, but the Python side tested only shutil.which, so it promised to skip the git+https triton requirement and then fetched it anyway. Same check on both sides now. * [pre-commit.ci] auto fixes from pre-commit.com hooks for more information, see https://pre-commit.ci * Never elevate for optional build tools Re-raising code 2 turned the optional set into a NEED_SUDO handshake, so a box missing cmake or gcc got the desktop's mandatory permission dialog, whose Cancel drops back to not-installed. That re-imposes through a prompt the build-tool requirement this gate removes, and none of those tools are needed to run. Suppress the handshake for optional callers; a required package still elevates. Verified in sh, dash and bash. Also advance the progress bar on the no-git triton skip, which otherwise ends at 14/15. * Tighten the comments on the dependency gate * Correct why the PyAV cap is needed 16.0.0 does ship cp313-cp313-macosx_14_0_arm64; the comment claimed no cp313 wheel exists. The actual reason is the deployment target: 15.1.0 is macosx_13_0 and 16+ is macosx_14_0, so the cap is what keeps macOS 13 off a source build. * Tighten the installer gate comments * Cap cryptography on x86_64 macOS so the consumer install needs no Rust cryptography 49.0.0 (2026-06-12) dropped the macosx_10_9_universal2 wheel and now ships macosx_11_0_arm64 only, so x86_64 macOS has no wheel and uv falls back to the sdist. That build calls maturin, which pulls Rust and then fails at 'linking with cc failed' on a clean Mac without the Xcode Command Line Tools. It surfaced in the clean-machine leg mac macos-15-intel / mask / file, several minutes into the studio dependency step, which is exactly the up-front toolchain requirement this branch removes. 48.0.1 is the newest release carrying a universal2 wheel, and its cp39-abi3 / cp311-abi3 tags cover the 3.12 and 3.13 interpreters the installer creates. The cap is marker-scoped to darwin + x86_64, so arm64 macOS and every other platform still resolve to the latest. Lift it when cryptography ships an x86_64-capable macOS wheel again. Resolution of studio/backend/requirements/studio.txt under this constraints file gives 48.0.1 on x86_64-apple-darwin and 49.0.0 on aarch64-apple-darwin and x86_64-unknown-linux-gnu, on both 3.12 and 3.13. * Correct the av note now that cryptography also compiles on macOS * Never escalate for optional apt packages outside Tauri mode The optional bypass sat inside the TAURI_MODE branch, so a plain curl | sh install on a non-root Debian or Ubuntu box still fell through to the escalation branch and showed the default-yes permission prompt for cmake, GCC and the libcurl headers. That is exactly the toolchain this change set declared unnecessary on the consumer path, so the prompt asked for a password to install packages nothing here uses, and a headless run failed the same way instead of falling through to prebuilt llama.cpp. Move the check above the mode split so optional callers return 2 in both modes. Required packages such as curl still escalate unchanged. --------- Co-authored-by: danielhanchen Co-authored-by: pre-commit-ci[bot] <66853113+pre-commit-ci[bot]@users.noreply.github.com> --- install.sh | 196 +++++++++++----- .../backend/requirements/extras-no-deps.txt | 4 +- .../requirements/single-env/constraints.txt | 17 ++ studio/install_python_stack.py | 49 +++- tests/sh/test_linux_deps_gate.sh | 210 ++++++++++++++++++ tests/sh/test_macos_clt_gate.sh | 165 ++++++++++++++ 6 files changed, 574 insertions(+), 67 deletions(-) create mode 100755 tests/sh/test_linux_deps_gate.sh create mode 100755 tests/sh/test_macos_clt_gate.sh diff --git a/install.sh b/install.sh index 72f2455277..fc9aa0a431 100755 --- a/install.sh +++ b/install.sh @@ -800,8 +800,17 @@ _smart_apt_install() { return 0 fi - # In Tauri mode, report needed packages and exit — Rust handles elevation + # Optional callers never elevate, in any mode: nothing on the consumer path + # builds anything, so neither the terminal sudo prompt below nor the Tauri + # NEED_SUDO dialog (whose Cancel leaves the user not installed) may gate the + # run over unused tools.

Confirmed: neither PR touches cleanup_child_processes. Quitting runs cleanup_child_processes -> install::stop_install, which SIGTERMs the installer's process group. In the reported session that landed at "5/10 studio deps", so the venv kept the CLI's dependencies and lost the server stack, and the next launch died on `import structlog`. Three minutes of installing, destroyed with no warning and no way back. So ask. Only from the tray Quit item -- a deliberate action with a UI present.

Measured, piping this file into sh and forcing an early exit: before: writer rc=141 (SIGPIPE) reader rc=1 after: writer rc=0 reader rc=1 Through a real curl against a local server, curl rc went 23 -> 0 while the installer's own exit code kept propagating.

Nothing raises while kernels/utils.py binds them at module scope, so device_type.py's guarded import sees a healthy wheel, ALLOW_BITSANDBYTES stays true, loader.py forwards the default load_in_4bit=True and the run dies inside a kernel instead of degrading to 16bit. Probe the handles the kernels actually bind and clear the flags when they are not native. A real handle is a ctypes function pointer and carries restype; a deferred failure is a Python function and does not. Scoped to the capability flags on purpose. The module stays bound and get_ptr keeps pointing at bitsandbytes, because these shapes import perfectly well and treating them as absent would disable a wheel whose Python side works - a CPU-only install is exactly that shape. * [pre-commit.ci] auto fixes from pre-commit.com hooks for more information, see https://pre-commit.ci * Only clear the flags when the native library is dead, not partially exporting ALLOW_BITSANDBYTES gates 8bit as well as 4bit - loader.py:505-510 clears both - so failing the check on one missing 4bit symbol would silently downgrade an otherwise valid LLM.int8 request to 16bit. A library that exports some of these handles is alive; only one where none of them is a ctypes function pointer is dead, which is the CPU-only and ErrorHandlerMockBNBNativeLibrary case this exists for. A genuinely missing symbol raises where kernels/utils.py binds it, so it is a crash no capability flag can rescue and not something to trade 8bit for. * Gate the bitsandbytes ctypes binds on the same verdict as the flags Clearing ALLOW_BITSANDBYTES is not enough on its own. kernels/utils.py guarded the bnb.functional.lib.* binds on `bnb is None` alone, so an importable but dead wheel still reached them at module scope: bitsandbytes 0.45.5, the floor in pyproject.toml, sets functional.lib = None when the native library fails to load, and None.cdequantize_blockwise_fp32 raises right there. That kills import unsloth outright instead of degrading to 16bit, which is the fallback the cleared flag exists to reach. Reuse native_kernels_ready so the bind path and the flag path agree, and take the _bnb_required branch when they say the library is dead. Touches only the guard expression, not the binds themselves. * Tighten the comments on the bitsandbytes kernel readiness probe * Require every probed handle, and license the module Apache like the rest of unsloth The readiness verdict now gates the module-scope ctypes binds as well as the flags, so "at least one handle is native" is no longer the right question. A library that resolves one symbol and not another passed the probe and then raised AttributeError at the bind the probe exists to prevent. Require all of them. That costs 8bit in the partial case, since ALLOW_BITSANDBYTES gates both, but a wheel missing a symbol is a shape no flag can make safe and refusing it beats crashing on it.

Add CHANGELOG.md at the repo root as the source of release notes. Studio reads it from the default branch, so editing the file updates the popup without a release or rebuild, and falls back to the copy bundled in the install when the repo is unreachable. Notes are matched to one exact version. The popup asks for the version it is offering and gets that section or nothing, so an older release's notes can never appear next to a newer update. When there is no match the popup links out to the online changelog instead. The collapsed popup previews the top bullets with the leading sentence highlighted; "Show release notes" expands the full notes in a scrollable panel. Applies to both the browser and desktop banners, and the desktop updater's own release body is used when CHANGELOG.md has no matching section. * [pre-commit.ci] auto fixes from pre-commit.com hooks for more information, see https://pre-commit.ci * Address review: fence matching, nested bullets, BOM, updater notes field Track the opening fence marker and length so a ``` sample inside a ```` block does not close it early and let the sample's heading be indexed as a real release. Preserve list indentation in the preview and take only top-level bullets, so nested detail no longer consumes the four headline slots. Strip a UTF-8 BOM before parsing. An editor on Windows can leave one on the first line, which hid a section whose heading started the file. Read `notes`/`pub_date` from latest.json in the manual Linux updater path, with aliases for the older `body`/`date`. The workflow publishes Tauri's field names, so the manual path's release body was always empty. Also loop the preview tag strip until stable for CodeQL js/incomplete-multi-character -sanitization; the value renders as text, so this is defence in depth. * Address review: bare fence closers, HTML comments, underscores, notes URL A closing fence must carry nothing after the delimiter, so a ```` line with trailing text inside a ```` block is content rather than the end of it. Both the parser and the preview extractor follow that rule now. Skip headings inside HTML comments. A commented-out section is not rendered by Markdown, so it must not be indexed as a release. Strip only paired emphasis and park code spans first, so identifiers keep their underscores: UNSLOTH_DISABLE_UPDATE_CHECK was previewing as UNSLOTHDISABLEUPDATECHECK. Prefer the caller's release URL over the API's generic changelog link, so the desktop fallback points at the release page for the version being offered. Look at the repo-root CHANGELOG.md before the packaging snapshot, and remove the snapshot after build.sh, so an edited root file is never shadowed by a stale copy. Also nudge the notes container radius from 16px to 14px. * [pre-commit.ci] auto fixes from pre-commit.com hooks for more information, see https://pre-commit.ci * Address review: comparison operators, hidden comments, remote failures Require a name character after "<" when stripping tags. A bullet reading "Support Python <3.15 and >3.9" previewed as "Support Python 3.9", because the operators were consumed as if they were a tag. Track HTML comments while collecting preview lines. A commented-out bullet was previewed as a published change even though Markdown never renders it. Report a remote lookup failure whenever nothing matched. The bundled changelog cannot know a version newer than the install, so discarding the error made an offline lookup read as "no notes were published". The hook now treats a reported failure as its retryable error state. * [pre-commit.ci] auto fixes from pre-commit.com hooks for more information, see https://pre-commit.ci * Address review: code-span delimiters, stale notes, retry past cached failures Treat an HTML comment delimiter inside inline code as literal. A note reading "Type ` and are complete comments in CommonMark: the closer overlaps the opener, so searching for --> past the opener never found it and the scanner stayed in comment state for the rest of the file. An empty comment used as a section marker hid every release below it, in both the backend parser and the frontend preview. get_remote_changelog cleared its single-flight flag only after except Exception, so a BaseException stranded it and every later caller waited out the full deadline for the life of the process. Move the release into a finally. * [pre-commit.ci] auto fixes from pre-commit.com hooks for more information, see https://pre-commit.ci * Compare resolved changelog paths instead of a hardcoded checkout name The ordering assertion matched the string suffix /unsloth/CHANGELOG.md, so it raised StopIteration in any checkout not literally named unsloth, and on Windows the separator is a backslash so the suffix never matched there either. Both are unrelated to the ordering under test. Verified failing on ubuntu-24.04, macos-14-arm64 and windows-2025 alike, and passing after. * [pre-commit.ci] auto fixes from pre-commit.com hooks for more information, see https://pre-commit.ci * Scan backtick runs once instead of rescanning the suffix per opener Every unmatched opener rescanned the rest of the line and the outer loop then advanced by a single run, so a line of runs of 1, 2, 3 ... backticks was quadratic: 321 KB took 7.688s, and release notes are reparsed on every popup request, so one malformed remote changelog could tie up backend workers across installed clients. Collect the runs in one pass and walk a cursor per run length, since a length that runs out of partners stays out. Same 321 KB now takes 0.013s and 5 MB takes 0.205s. Verified identical output against the old implementation on 30000 randomized lines. * Read type 6 and 7 HTML containers in the link resolver too The resolver masked only type 1 blocks (pre, script, style, textarea), while the backend parser and the collapsed preview already apply the type 6 and 7 rules, so the three disagreed on the same notes. A
or
with no blank line inside is a type 6 block whose contents render verbatim, so two things went wrong there: a relative link was rewritten into text the reader sees literally, and a fence inside the block was taken for a real fence, which silently stopped every link below it from resolving. A blank line, not the closing tag, ends these blocks, so the common '
' followed by a blank line still holds Markdown and still resolves. * Mask comments before fences, split only on Markdown line endings, stage the snapshot Three separate reports, all confirmed against head. The link resolver tracked no comment state, so a fence delimiter hidden inside an HTML comment was read as a real fence. The fence then stayed open and every visible line below was classified as code, so none of its links resolved: one commented-out draft containing a stray backtick run silently broke the rest of the notes. Comments are masked now, but only outside a fence, since fenced content is literal and a comment opener in it is not one. Commented ranges join the code spans, so a link the reader cannot see is not rewritten either. Verified with 9 cases under node; 2 fail on the previous file. str.splitlines also breaks on U+2028, U+2029, NEL, vertical tab and form feed, none of which end a line in CommonMark. A separator sitting in prose ahead of "## 9.9.9" made the parser index a release that renders nowhere and truncate the notes above it: measured, the version list went from 2.0, 9.9.9, 1.0 to 2.0, 1.0 and the 2.0 body stopped being cut at the separator. The build wrote the snapshot beside the checked-in sources, so a PEP 517 build against an immutable checkout (Nix, Bazel, a read-only container mount) raised PermissionError before build_py started and produced no wheel at all. The source-tree copy is best effort now and the wheel takes its copy from the staging directory. Reproduced both ways against a read-only package dir. * [pre-commit.ci] auto fixes from pre-commit.com hooks for more information, see https://pre-commit.ci * Use the backend's heading and quote marker rules in the preview An ATX heading needs an ASCII space or tab after the marker, which is exactly what _HEADING_PATTERN requires. The \s class also matches a non-breaking space, so prose beginning "## Important change" with one was classified as a heading and discarded by collectBullets, and a prose-only release then had no collapsed preview at all rather than a wrong one. A blockquote marker takes at most three leading spaces, like every other marker in this file. Accepting any run let an indented code sample containing "> - sample output" shed its indentation and enter the collector, so a release with no real bullets showed code as its summary. Both reproduced under node against the real module: the two cases fail on the previous file and pass now, with a real heading, a real quoted bullet and an ordinary bullet unchanged. * [pre-commit.ci] auto fixes from pre-commit.com hooks for more information, see https://pre-commit.ci * Collect preview reference labels only from lines that can be definitions A definition-shaped line inside an indented code block or a deep fence is literal text, so CommonMark leaves a later "[Beta] support" unresolved with its brackets showing. The pre-scan ran over every line regardless, so the label was recorded and toPlainText stripped the brackets: the collapsed preview claimed a resolved reference the expanded notes do not have. It now skips the same code the collector pass skips. A real definition takes at most three spaces of indentation, so the indent test cannot reject one, which the second case checks. Reproduced under node: the indented-code definition resolved "Beta support" before and keeps its brackets now. * [pre-commit.ci] auto fixes from pre-commit.com hooks for more information, see https://pre-commit.ci * Let a document-level HTML block close an open list item CommonMark HTML blocks of types 1 to 6 interrupt a paragraph, so a "
" to the left of an open list item closes it and a following one-to-three-space indented "## 2.0" is a real document heading. Two things stopped that: the block opener was blanked before the list tracker saw it, so it read as a blank line, and _may_be_lazy treated it as ordinary text that could continue the item's paragraph. The item therefore stayed open and the release below the block was swallowed entirely. The opener's indentation is now taken before it is hidden, the way a fence opener's already was, and an HTML block opener is no longer a candidate for lazy continuation. Type 7 cannot interrupt a paragraph and is deliberately excluded, since after_paragraph is the only state this helper is asked about. Measured on the reported shape: the version list went from 3.0, 1.0 to 3.0, 2.0, 1.0. The test also pins the two cases that must not change, an indented heading genuinely nested in an item and an ordinary lazy continuation, both of which still suppress the heading. * Let the download panel shrink inside the capped overlay stack The bottom-right stack is capped to the viewport, but a flex item defaults to min-height:auto, so the download panel's outer wrapper could not shrink below its own content. min-h-0 had been added to the nested panel and not to this wrapper, so on a short viewport the cap was absorbed by the update card, whose header and actions are fixed, instead of by the download list, which scrolls. Only the shared-stack branch takes it. Standalone is positioned fixed and is not a flex item at all. * [pre-commit.ci] auto fixes from pre-commit.com hooks for more information, see https://pre-commit.ci * Tighten release notes comments Shorten the comments and docs added with the update popup release notes so each explains its line in as few words as possible. Comments only, no behaviour change. * Measure release-notes indentation from the container CommonMark measures a block's indentation from its container, not from the left margin (spec 0.31.2 sections 4.4 and 5.2). The three changelog scanners measured from the margin in different places, so they disagreed with the renderer and with each other. Under "- Details:" the content column is 2, so a four-space line is two columns in: a paragraph holding a link. The link resolver read it as an indented code block and left the destination relative, so it resolved against Studio's own origin instead of the repository. At document level the same four spaces really are code, and a top-level bullet is not indented enough to continue the block. The preview promoted an indented line that looked like a fence opener to a list-contained fence, so with no later closer every bullet below it was skipped and the collapsed popup lost its summary. A fence is scoped to its container too: with no closing line it runs to the end of the containing block, not the end of the document (section 4.5). A dedented "## 2.0" closes the list item the fence sits in, so it is a real release heading. Document-wide fence state kept the block open, so one missing closing line hid every release below it. Both frontend scanners now read their list columns from one module ported from the backend's own tracker, which keeps the three in step. Two smaller fixes ride along. A release body written as a GFM table rendered as a grid but previewed as its raw "| Change | Detail | | --- | --- |" delimiters, so table rows are now dropped from the collapsed summary the way a code block already is. The comment scanner restarted its code-span search at the first span for every opener, so a line of N spans and N openers cost N squared: a 203 KiB line, well inside the 2 MiB the fetcher accepts, took 10.9s and now takes 41ms. Differential fuzzing against a CommonMark reference implementation puts the parser's heading mismatches at 11 of 14275 documents, down from 617, and the link resolver's at 147 of 6000, down from 217. * Keep Retry reachable when the release notes fetch fails The panel took fallbackMarkdown for every response that did not match, error included, so markdown was always truthy on desktop and the error branch that carries the Retry button was unreachable. The fallback there is the updater's static install blurb, not this release's notes, so a transient failure showed "Download the Apple Silicon .dmg" where the notes should be, with no way to ask again until the cache expired. The hook already separates the two: a reported failure is error and retryable, "no section for this version" is ready and is not. The fallback now applies only to the second, which is the case its prop documents. * [pre-commit.ci] auto fixes from pre-commit.com hooks for more information, see https://pre-commit.ci * Scope an unclosed comment to its block and end a release on a bare ## Two CommonMark rules the changelog scanners read too strictly. An HTML block only opens when the line itself begins with a comment marker (spec 0.31.2 section 4.6, type 2). One written mid-sentence is inline raw HTML and, unclosed, is ordinary text. The link resolver carried the open state to every line below instead, so a note reading "- Type " may arrive on a later line of that same paragraph. Ending it at its own line left a backtick inside it pairing with a real one below, which hid a following link from the resolver, and left the preview quoting text the popup body does not show. A shared commentClosesBelow answers whether the closer arrives before the paragraph breaks; where it does not, the opener stays the ordinary text a renderer shows, so a note that merely mentions "` is reachable from an opener read any line whose first character was punctuation as the start of a new block. A `-->` written on a line of its own is how a multiline comment is ordinarily closed, and a wrapped line may open with emphasis, so neither counted as more of the paragraph carrying the comment. The comment never closed and the collapsed popup showed the author's internal note to the reader. It now tests for a block that may actually interrupt a paragraph. A comment is an HTML block too (section 4.6, type 2), so one written as a list item's first content opens inside that item exactly as a fence written there does. All three scanners looked for the opener at the margin of the line as written, so a marker in front of it hid the block: the resolver rewrote a destination inside raw HTML, which Streamdown then shows the reader as a literal URL, and the preview quoted the hidden note back at them as though the bullet were Markdown. The opener is now read from the item's content, the marker survives into the structural line so the item it opens is still tracked, and the block is scoped to that item the way a fence there is. * [pre-commit.ci] auto fixes from pre-commit.com hooks for more information, see https://pre-commit.ci * Tighten the release notes comments without losing the reasons they record --------- Co-authored-by: Unsloth Co-authored-by: pre-commit-ci[bot] <66853113+pre-commit-ci[bot]@users.noreply.github.com> Co-authored-by: danielhanchen --- .github/workflows/release-desktop.yml | 3 + .gitignore | 3 + CHANGELOG.md | 88 + MANIFEST.in | 2 + _changelog_build.py | 36 + build.sh | 6 +- pyproject.toml | 5 + studio/backend/main.py | 13 + studio/backend/utils/changelog.py | 1056 +++++++++ studio/backend/utils/update_status.py | 24 +- studio/frontend/src/app/provider.tsx | 12 +- .../src/components/llama-update-banner.tsx | 2 +- .../src/components/tauri/update-banner.tsx | 67 +- .../components/update/release-notes-panel.tsx | 251 +++ .../src/components/web/update-banner.tsx | 42 +- .../download-manager-panel.tsx | 6 +- .../frontend/src/hooks/use-release-notes.ts | 146 ++ studio/frontend/src/hooks/use-tauri-update.ts | 15 + studio/frontend/src/lib/changelog-links.ts | 664 ++++++ .../frontend/src/lib/markdown-code-spans.ts | 123 ++ .../src/lib/markdown-inline-comments.ts | 62 + .../frontend/src/lib/markdown-list-columns.ts | 357 +++ .../frontend/src/lib/release-notes-preview.ts | 1005 +++++++++ studio/src-tauri/src/desktop_update_policy.rs | 15 +- tests/studio/test_update_release_notes.py | 1906 +++++++++++++++++ 25 files changed, 5874 insertions(+), 35 deletions(-) create mode 100644 CHANGELOG.md create mode 100644 MANIFEST.in create mode 100644 _changelog_build.py create mode 100644 studio/backend/utils/changelog.py create mode 100644 studio/frontend/src/components/update/release-notes-panel.tsx create mode 100644 studio/frontend/src/hooks/use-release-notes.ts create mode 100644 studio/frontend/src/lib/changelog-links.ts create mode 100644 studio/frontend/src/lib/markdown-code-spans.ts create mode 100644 studio/frontend/src/lib/markdown-inline-comments.ts create mode 100644 studio/frontend/src/lib/markdown-list-columns.ts create mode 100644 studio/frontend/src/lib/release-notes-preview.ts create mode 100644 tests/studio/test_update_release_notes.py diff --git a/.github/workflows/release-desktop.yml b/.github/workflows/release-desktop.yml index 081eda4e32..0a8d71610d 100644 --- a/.github/workflows/release-desktop.yml +++ b/.github/workflows/release-desktop.yml @@ -766,6 +766,7 @@ jobs: env: GH_REPO: ${{ github.repository }} APP_VERSION: ${{ needs.prepare-version.outputs.app_version }} + PYPI_VERSION: ${{ needs.prepare-version.outputs.pypi_version }} STUDIO_VERSION: ${{ needs.prepare-version.outputs.studio_version }} DESKTOP_RELEASE_TAG: ${{ needs.prepare-version.outputs.desktop_release_tag }} DESKTOP_PRERELEASE: ${{ needs.prepare-version.outputs.prerelease }} @@ -911,6 +912,8 @@ jobs: notes = pathlib.Path(os.environ['RUNNER_TEMP'], 'desktop-release-notes.md').read_text() metadata = { 'version': os.environ['APP_VERSION'], + # App version is SemVer; CHANGELOG.md is keyed by the backend release. + 'pypi_version': os.environ['PYPI_VERSION'], 'notes': notes, 'pub_date': datetime.datetime.now(datetime.timezone.utc).isoformat(timespec='milliseconds').replace('+00:00', 'Z'), 'platforms': { diff --git a/.gitignore b/.gitignore index fafd17aa95..fa6997cb06 100644 --- a/.gitignore +++ b/.gitignore @@ -208,6 +208,9 @@ tmp/ **/node_modules/ auth.db +# Packaging snapshot of the root CHANGELOG.md (written by build.sh) +studio/CHANGELOG.md + # Tauri local build/generated output studio/src-tauri/target/ studio/src-tauri/gen/ diff --git a/CHANGELOG.md b/CHANGELOG.md new file mode 100644 index 0000000000..241e013cea --- /dev/null +++ b/CHANGELOG.md @@ -0,0 +1,88 @@ +# Changelog + +Release notes for Unsloth and Unsloth Studio. + +Unsloth Studio reads this file to show release notes inside the "New Unsloth +version" update popup.

On Windows that is the ANSI codepage (cp1252, cp932, cp1251, ... by system locale), never UTF-8. Hugging Face writes these files as raw UTF-8, so every read of one decodes with the wrong codec: - tokenizer_config.json, which holds the chat template. Templates routinely carry -> arrows, smart quotes and CJK, so this is the common path into chat - config.json and adapter_config.json - modules.json, Ollama manifests, and the .py sources the remote-code scanner reads before a model is allowed to load The llama-server and embedding-server stdout readers have the same problem via subprocess(text = True); they now decode utf-8 with errors = "replace" so a stray byte cannot kill a log reader. Encoding arguments only, no logic changes. tests/test_chat_text_encoding.py covers a config.json and a chat template holding umlauts, arrows and CJK, plus the remote-code scanner reading a source file with umlauts. Those pass anywhere the locale is already UTF-8, so a fourth test re-runs the readers under -X warn_default_encoding and fails on any platform if an encoding argument goes missing again. * [pre-commit.ci] auto fixes from pre-commit.com hooks for more information, see https://pre-commit.ci * Studio: name utf-8 explicitly on the remaining text I/O, with an AST guard (#7465) * Studio: name utf-8 explicitly on the remaining text I/O Follow-up to the model-text reads in #7467, covering the rest of the backend: system probes (nvidia-smi, amd-smi, powershell, git, node), package installers, /proc and /sys readers, and internal marker files (pid, install id, bootstrap password, Colab credentials). Same reason as #7467. open(), Path.read_text()/write_text() and subprocess(text = True) fall back to locale.getencoding(), which on Windows is the ANSI codepage rather than UTF-8. These paths are mostly ASCII today, so this is hardening, not a live bug. Encoding arguments only, no logic changes. Adds tests/test_text_io_encoding.py: an AST guard walking every backend source and asserting text I/O names its encoding, so the class of bug cannot creep back in one call at a time. 275 files. * [pre-commit.ci] auto fixes from pre-commit.com hooks for more information, see https://pre-commit.ci * Catch aliased subprocess and positional Path.open, migrate legacy JSONL The guard only matched a receiver literally named subprocess, so worker.py's `import subprocess as _sp` hid three text = True installs that decode pip output with the ANSI codepage. It also skipped any .open() with more than one positional argument, though Path.open takes buffering/encoding/errors/newline positionally. Resuming a scrape written by an older release is the other half: those JSONL lines are in the locale codepage, so the UTF-8 preload raised, the dedup keys were silently forgotten and duplicates were appended to a now mixed-encoding file. Decode with the locale codepage as fallback and rewrite as UTF-8 before the append handle opens, since Windows cannot replace a file it holds open. * Stream the JSONL preload and keep a torn line from relabelling the shard Reading the whole shard to migrate it was wrong twice over. These files reach gigabytes on a large scrape, so the preload now streams line by line and the rewrite streams through a temp file. Worse, one interrupted append used to condemn the file: the whole-file UTF-8 decode failed, every byte was retried as cp1252, and the rewrite persisted mojibake over records that were fine. A line now counts as legacy only if the locale codepage both decodes it and yields valid JSON, which a torn UTF-8 line does not. Damaged lines are skipped and copied through byte for byte. When the rewrite cannot be written at all, the append handle opens with the legacy encoding rather than mixing UTF-8 into the file. install_wheel takes run = subprocess.run as a parameter, so the guard cannot see it. Both wheel installs there now name their encoding. * Decide the shard's encoding from the file, not one line at a time Some byte strings parse both ways. cp1251 `Р°` is D0 B0, which is also valid UTF-8 for `а`, so a UTF-8-first parse quietly showed the wrong text instead of migrating it. A line now yields both readings, and the file decides. Any line that parses under the codepage but not as UTF-8 is unambiguous evidence, and ambiguous lines then follow that verdict, which is enough for any real shard: ordinary Cyrillic or Japanese prose is invalid UTF-8 several times per line. Keys for ambiguous lines are re-derived from the legacy reading during the rewrite. A shard is undecidable only if every line is ambiguous, and nothing can tell those apart. latin-1 is also tried after the locale codepage, so a scrape carried from Windows to a UTF-8 machine still has a reading rather than none. Requiring valid JSON, not just a decode, keeps that from claiming torn lines. * Weigh the whole shard, and never lose a record on the fallback path One structurally valid JSON line carrying a stray 0x96 parses as cp1252, so a single-line verdict let it relabel a healthy shard and mojibake every good record in it. Each line with non-ASCII bytes now votes: parsing only under the codepage is evidence for legacy, parsing as UTF-8 is evidence against, since codepage text rarely forms valid multibyte UTF-8. Ties leave the file alone. When the migration cannot be written the append handle uses the legacy codepage, and errors = "replace" quietly turned characters it cannot hold into question marks while write() still reported success. That path now escapes to \uXXXX instead, which is ASCII, so every codepage holds it and json.loads returns the exact characters. Nothing needs replacing, so errors = "strict" is safe. stream_installer runs sys.executable, so its output is now decoded as UTF-8 by utf8_child_env rather than read as the ANSI codepage. * Only rewrite a shard we can attribute, and append ASCII when we cannot latin-1 was doing too much work. It reads any byte, so it gave a moved shard a reading, but it is the right text only for cp1252: cp1251 Привет came back as Ïðèâåò and the rewrite made that permanent. The codepage is now trusted only when it is the locale's, and an untrusted reading is never written back. That leaves three cases where the file holds bytes UTF-8 cannot read and we are not converting it: no codepage to attribute it to, ambiguous lines outvoting the unambiguous ones, and a preload that could not read the file at all. All three used to append UTF-8 into it. They now append pure ASCII, which every ASCII-compatible codepage stores identically, so the file keeps decoding exactly as it did and no record is lost. Keys from the two readings are also kept apart. A damaged line in a healthy shard was marked seen through its codepage reading, so the retry that would have replaced the unreadable record was refused as a duplicate. * Let the flash-attn install stub take the kwargs the installer now passes _run_kwargs gained encoding and errors, so the one stub in this file that spelled its signature out rejected the call. The other four here already take **kwargs; this one now matches. * Do not let a stuck temp file mask the migration failure unlink() on the failure path could raise in its own right, on a stale .utf8.tmp directory or a temp another process holds. That escaped the constructor instead of returning False, so the caller never reached the ASCII append fallback that keeps the shard single-encoding. The pip fallback in install_wheel also spawns a Python child, so it gets utf8_child_env like the probe above it already had. The uv and nvidia-smi children are native binaries, where PYTHONIOENCODING would do nothing. * Stop converting legacy shards; the encoding that wrote them is unknowable trusted only ever meant that the bytes parse under this machine's codepage, which for a single-byte codepage is nearly always true. A cp1251 shard opened on a cp1252 Windows box decodes cleanly and would have been rewritten with Привет as Ïðèâåò. That is the fourth way this rewrite could corrupt a shard, and the common cause is that a file's encoding cannot be recovered from its bytes. So the rewrite is gone. The shard is left exactly as found, and appends are pure ASCII whenever it holds bytes UTF-8 cannot read, which is what actually delivered the no-mixed-encoding guarantee the rewrite was added for. Dedup keys still come from whichever reading parses, since ids are ASCII either way. This also removes the temp file, so there is no longer any file mode or ACL to carry across. * Scan the sandbox shim; it is shipped code, not a build artifact sandbox_site is on the sandboxed child's PYTHONPATH for every Python run (tools.py:332, 2660), so excluding it let two unannotated text calls through in code we ship. Both read and write the remap sidecar, which holds file paths. The exclusion list is meant for build output only, so the directory comes off it and the two calls name their encoding. * Force the worker's pip children to UTF-8, and read DBCS keys with a DBCS codec The three installer calls run sys.executable -m pip with an inherited environment, so the parent decoded UTF-8 while the child emitted the ANSI codepage. They now go through utf8_child_env like the other Python children. Two tests asserted no env kwarg was passed as a stand-in for no HIP flag being injected. They now assert the flag itself, which is the guarantee they were written for and does not depend on how the env is delivered. Separately, latin-1 cannot stand in for a double-byte codepage while recovering dedup keys: cp932 表 is 95 5C, and the trail byte reads as a JSON backslash, so the record failed to parse and its id was forgotten, appending a duplicate on resume. cp932, cp936, cp949 and cp950 are tried too. The reading is still only ever used for keys, which are ASCII and identical whichever codec parses. * Require more than one legacy line before trusting its dedup keys A shard whose valid records are all ASCII casts no UTF-8 votes, so a single damaged line won the vote by itself, its key was remembered, and the retry that would have replaced the unreadable record was refused. One such line is genuinely undecidable: a legacy record with one accented character and an ASCII record with one stray byte are the same shape. Reading it as damage costs a duplicate; reading it as legacy loses the record for good. Only one of those is recoverable, so it is now read as damage. A real legacy shard has a legacy line for every record carrying an umlaut, so its dedup is unaffected. * Append ASCII whenever the shard already holds non-ASCII bytes The gate asked whether any line was undecodable as UTF-8, which misses a shard where every legacy line happens to be valid UTF-8 too. A cp1251 shard of Р° records is bytes D0 B0 throughout, so appending 世界 as UTF-8 left a file where cp1251 reads the old records correctly and the new one as mojibake, and UTF-8 does the reverse. No single decoding recovered the whole scrape. The gate is now simply whether the shard holds any non-ASCII byte at all, which covers both cases and is easier to reason about: if what is already there reads differently under different encodings, do not add more bytes that do. Appending ASCII costs only \uXXXX escapes, which json.loads turns back into the exact characters, and it leaves the new record correct under either reading. * Skip the two Linux-gated flash-attn tests off Linux _should_try_runtime_flash_attn_install ends in sys.platform.startswith( "linux"), and the threshold test one line above already asserts exactly that, so the two tests that drive _ensure_flash_attn_for_long_context past the gate cannot pass anywhere else: the call returns before it reports a status. They were written on Linux and only surface once the suite actually runs on Windows or macOS, where both fail on an empty status list. This PR is about making the backend behave on Windows, so its own suite should be runnable there. * Fail closed when a KFD topology node does not decode This PR pins that read to utf-8, which turns an undecodable byte into UnicodeDecodeError. That is a ValueError, not an OSError, so it slips past the handler one line below and escapes a helper whose docstring promises to fail closed on any unreadable node. The caller would then lose the whole HIP-order map on a machine that has AMD GPUs, and the reason the helper fails closed is that dropping a node shifts every later ordinal and lets a similar-capacity GPU pass the total-size guard while showing another card's usage. Widening the handler is the same one-line change main already made in #7487, so the two agree and the eventual merge is clean. * Tighten the comments added in this branch * Treat an undecodable marker and undecodable metadata as malformed, not fatal Two more places where pinning the decode changed the failure mode. A UnicodeDecodeError is a ValueError, so neither `except OSError` nor `except (JSONDecodeError, OSError)` catches it, and both sites had a documented fallback that stopped being reached. An undecodable .transport marker used to read as an unknown value, and the caller then safely purged and restarted the partial download. It now aborts prepare_cache_for_transport instead, so the transfer fails rather than retrying. Undecodable .meta.json used to fall back to the file's own name, the same way invalid JSON does. It now aborts URI construction for the entire unstructured seed, so one corrupt byte in original_filename takes out the whole dataset. Both handlers are widened, matching the KFD fix earlier on this branch. * [pre-commit.ci] auto fixes from pre-commit.com hooks for more information, see https://pre-commit.ci * Widen two more decode guards, and pin the kernel installer's pipe Same shape as the ones already fixed here: the read was pinned to UTF-8 while the handler around it still only catches OSError, and UnicodeDecodeError is a ValueError. hf_cache_snapshot_dir answers whether a model is already on disk, and the offline embedding checks turn a raise into a 500. A torn refs/main used to decode into a nonsense commit and miss the snapshot dir; it now skips that cache root and keeps looking. _remove_pid_file runs first in _graceful_shutdown, so a corrupt studio.pid raising there abandoned the inference, export, training and tunnel children the rest of that function exists to kill. ssm_runtime's source-build path builds its subprocess kwargs in a dict and splats them through _run_with_heartbeat, so neither the encoding guard nor the earlier sweep saw the text = True in it: pip's output was still decoded with the Windows ANSI codepage, where a non-ASCII path or a compiler diagnostic mojibakes or raises over an install that was going fine. It now pins the same utf-8/replace pair install_wheel uses, and the HIP branch extends that env rather than replacing it. The guard learned the dict-literal shape and reddens on the old code (ssm_runtime.py:253). * Tighten the comments around the UTF-8 text I/O pins Collapse the multi-line rationales added with the encoding pins down to a line or two each, drop what the code already says, and use one wording for the repeated child-env note. * Do not let an unreadable bootstrap password stop startup, and narrow the kwargs guard ensure_default_admin calls _load_bootstrap_password for every existing admin and the lifespan calls that with no handler, so pinning the decode turned a damaged or pre-pin .bootstrap_password file into a backend that will not start. We write that file ourselves in UTF-8, so a byte that will not decode belongs to a file whose plaintext is worthless anyway; it now reads as no bootstrap password, the same answer as an absent file. A readable one still loads. The new kwargs check also judged every dict literal in the tree, so an unrelated payload carrying "text": True would have been reported as subprocess configuration with a misleading message, and a dict that fills in its encoding on a later line would have been reported too. It now only judges a dict that actually reaches a call, either splatted through a name or written at the call site, and treats a later kw["encoding"] assignment as satisfying it. The ssm_runtime shape it was written for is still caught, and a test pins both directions. * Stop reading a UTF-8 record a second time _read_line always parsed the line under the codepage as well, even when it had already read as UTF-8. Both callers take the UTF-8 reading when there is one and never look at the other, so on a healthy shard the second parse is pure waste, and this file reads all of one on every resume of a scrape it expects to reach gigabytes. Measured on 200,000 records, 76 MB: 1.96s before, 0.81s after, so the double reading was costing 2.8x. The early return is limited to a record, since the key lookup deliberately falls through to the codepage reading when UTF-8 yields something that is not one. A line UTF-8 cannot read still tries the codepage, latin-1 and the double-byte encodings as before, which is what the second reading is for. * [pre-commit.ci] auto fixes from pre-commit.com hooks for more information, see https://pre-commit.ci * Pin the scanned source fixture's line endings test_remote_code_scan_reads_non_ascii_sources compared a file's contents against the string it wrote, but wrote it in text mode, so Windows translated the line ends on the way out and the read back differed by a carriage return. That is the writer's doing, not the encoding the test is about, and it was the one failure on the Windows runner that belonged to this branch. The fixture now writes with newline = "" so the bytes on disk are the string on every platform. * [pre-commit.ci] auto fixes from pre-commit.com hooks for more information, see https://pre-commit.ci * Trim the newer comments to their point Shorten the widened-guard and state store notes added since the last pass, and collapse the line-ending note on the scanned source fixture. * Read the scraper checkpoint as UTF-8 only, never as a codepage A checkpoint holds nothing but base64 cursors and booleans, so one written by an older locale-encoded release is byte-identical to a UTF-8 one and already reads back. The codepage fallback can therefore only ever contribute non-ASCII: if a single-byte reading of the file were all ASCII, the UTF-8 read would have succeeded first. So the only file it changes the answer for is a damaged one, and there it turns a safe reset into a resume on a mojibaked cursor. GitHub answers that with INVALID_CURSOR_ARGUMENTS at HTTP 200, gh_client returns the partial document, and the scraper reads zero nodes and an empty pageInfo, which marks the stream done. Every later resume then skips it entirely. Reading UTF-8 only restores the earlier behaviour of dropping a checkpoint that will not decode, which re-scrapes from the first page while the writers dedup the replay. The shard scan below keeps its codepage reading; those records do carry non-ASCII. * [pre-commit.ci] auto fixes from pre-commit.com hooks for more information, see https://pre-commit.ci * Gate the remaining tilelang install tests to Linux _tilelang_platform_supported() returns False off Linux, so _ensure_tilelang_backend returns before the install and the subprocess mock these six assert on is never called. They fail on macOS runners for that reason alone. The rest of the file already carries this marker; these were missed. * Gate the Windows-incompatible worker and ROCm tests Two different gates, because the production code has two. The causal-conv1d and flash-linear-attention installers bail out on sys.platform == 'win32' alone and run everywhere else including macOS, so those cases get not_on_windows; marking them linux_only would skip tests that legitimately pass off Linux. The DRM and KFD readers return early unless platform.system() is Linux, and their fixtures build a fake sysfs tree needing PCI addresses like 0000:00:02.0 as directory names, which Windows cannot represent, so those get linux_only. The two visible-utilization cases failed for a different reason: on Windows get_visible_gpu_utilization takes the AMD adapter branch ahead of the torch fallback under test, and probing it imports torch, which the runner lacks. Stubbing that branch empty leaves every other platform unchanged. * Treat unparseable JSON nesting as a parse failure, and guard os.fdopen json.loads answers nesting it cannot descend with RecursionError, a RuntimeError, so _parse let it escape where the catch-all it replaced discarded the record. Both callers run _parse outside any further handler, so one damaged checkpoint or shard line aborted the scraper at startup. The encoding guard also missed os.fdopen, which is open() on a descriptor and takes the same locale default in text mode. It flags exactly the two text-mode calls that were left unencoded; the swap lock file's reader was already pinned to UTF-8 while its writer still used the codepage. * [pre-commit.ci] auto fixes from pre-commit.com hooks for more information, see https://pre-commit.ci * Write the non-ASCII source fixture without a 3.10-only argument Path.write_text() only grew newline in 3.10, and pyproject declares requires-python >=3.9, so this raised TypeError there. open() takes the same argument on every supported version and pins the bytes on disk the same way. * [pre-commit.ci] auto fixes from pre-commit.com hooks for more information, see https://pre-commit.ci * Tighten encoding comments * Follow subprocess calls through callable aliases in the encoding guard --------- Co-authored-by: Unsloth <michaelhan@Michaels-MacBook-Pro.local> Co-authored-by: pre-commit-ci[bot] <66853113+pre-commit-ci[bot]@users.noreply.github.com> Co-authored-by: danielhanchen <unslothshared@gmail.com> --------- Co-authored-by: Unsloth <michaelhan@Michaels-MacBook-Pro.local> Co-authored-by: pre-commit-ci[bot] <66853113+pre-commit-ci[bot]@users.noreply.github.com> Co-authored-by: danielhanchen <unslothshared@gmail.com> --- studio/backend/auth/storage.py | 8 +- studio/backend/cloudflare_tunnel.py | 1 + .../data_recipe/local_callable_validators.py | 2 + studio/backend/core/inference/inference.py | 2 +- studio/backend/core/inference/llama_cpp.py | 20 +- studio/backend/core/inference/worker.py | 4 +- studio/backend/core/rag/embed_llama_server.py | 4 + studio/backend/core/rag/embeddings.py | 4 +- studio/backend/core/training/worker.py | 11 + studio/backend/hub/services/models/ollama.py | 4 +- studio/backend/hub/utils/download_registry.py | 2 + studio/backend/loggers/config.py | 8 +- .../scraper_impl/state_store.py | 193 ++++- .../data_designer_unstructured_seed/impl.py | 2 + studio/backend/routes/inference.py | 2 +- studio/backend/routes/models.py | 8 +- studio/backend/run.py | 2 + .../backend/tests/test_chat_text_encoding.py | 195 +++++ .../test_rocm_multi_gpu_vram_system_wide.py | 45 + studio/backend/tests/test_text_io_encoding.py | 809 ++++++++++++++++++ .../tests/test_training_worker_flash_attn.py | 66 +- studio/backend/utils/child_stdio.py | 22 + studio/backend/utils/hardware/amd.py | 2 + studio/backend/utils/hardware/hardware.py | 4 + studio/backend/utils/hardware/nvidia.py | 8 + studio/backend/utils/llama_cpp_update.py | 9 +- studio/backend/utils/mlx_repair.py | 4 +- studio/backend/utils/models/checkpoints.py | 8 +- studio/backend/utils/models/model_config.py | 33 +- studio/backend/utils/node_runtime.py | 2 + studio/backend/utils/paths/storage_roots.py | 2 +- studio/backend/utils/prebuilt/update_flow.py | 8 +- studio/backend/utils/security/consent.py | 4 +- .../backend/utils/security/file_security.py | 6 +- .../utils/security/remote_code_approvals.py | 2 +- .../utils/security/remote_code_scan.py | 8 +- studio/backend/utils/ssm_runtime.py | 10 +- studio/backend/utils/studio_version.py | 4 + studio/backend/utils/transformers_version.py | 36 +- studio/backend/utils/utils.py | 2 + studio/backend/utils/wheel_utils.py | 14 +- studio/backend/utils/whisper_cpp_update.py | 9 +- 42 files changed, 1480 insertions(+), 109 deletions(-) create mode 100644 studio/backend/tests/test_chat_text_encoding.py create mode 100644 studio/backend/tests/test_text_io_encoding.py create mode 100644 studio/backend/utils/child_stdio.py diff --git a/studio/backend/auth/storage.py b/studio/backend/auth/storage.py index 5f80ad89a3..35135b21eb 100644 --- a/studio/backend/auth/storage.py +++ b/studio/backend/auth/storage.py @@ -76,7 +76,13 @@ def _load_bootstrap_password() -> Optional[str]: global _bootstrap_password _bootstrap_password = None if _BOOTSTRAP_PW_PATH.is_file(): - bootstrap_password = _BOOTSTRAP_PW_PATH.read_text(encoding = "utf-8").strip() + # No caller handles a raise, so an unreadable file has to mean "no bootstrap + # password", not a dead backend.

Git merged both cleanly because they touch different lines, so the break only shows at test time. Match "lib.cdequantize_blockwise_fp32" instead. That still pins the binds to the guard, which is what the test is for, and no longer breaks when the module alias changes.

Settings search matched a row's visible label only, so "models folder", "directory", "path" and "drive" all returned nothing, and users concluded the location could not be changed at all. Hub > On-device locations now leads with a Download location row: current path, Change (folder browser on web, native picker on desktop), Use default, free space, and a note when HF_HOME pins it. That dialog is where people already look for where models live, but it only managed read-only scan folders. Changing the location refreshes the inventory. Settings search now also matches per-row keyword aliases, so "folder", "directory", "path", "location", "drive", "disk" and "cache" find the row. Relabels it "Models folder" and says it can be moved off the system drive. Adds the German strings for the block, which fell back to English. * Re-read the download location on every open, and drop it when the read fails The dialog stays mounted between opens, so a reopen that hit a failing or slow GET /api/settings/hugging-face-cache kept showing the previous path with Change and Use default still enabled, as though it had just been confirmed. The loaded flag is re-armed on each open and a failed read now clears the settings, so the field falls back to Unknown and both buttons disable until a read succeeds. * Let the inventory version bump be the only refresh after a cache move updateHuggingFaceCacheSettings already bumps the inventory version, which re-fetches every source. Calling onInventoryChange as well started a second round under the previous version, and the differing keys meant the two could not be deduplicated, so moving the folder scanned everything twice. The settings Resources tab already relies on the bump alone for the same call. --------- Co-authored-by: Unsloth <michaelhan@Michaels-MacBook-Pro.local> --- .../hub/catalog/on-device-folders-dialog.tsx | 165 +++++++++++++++++- .../frontend/src/features/settings/index.ts | 5 + .../src/features/settings/settings-dialog.tsx | 13 +- .../src/features/settings/settings-search.ts | 12 ++ studio/frontend/src/i18n/locales/ar.ts | 2 + studio/frontend/src/i18n/locales/de.ts | 16 +- studio/frontend/src/i18n/locales/en.ts | 8 +- studio/frontend/src/i18n/locales/es.ts | 2 + studio/frontend/src/i18n/locales/fr.ts | 2 + studio/frontend/src/i18n/locales/hi.ts | 2 + studio/frontend/src/i18n/locales/ja.ts | 2 + studio/frontend/src/i18n/locales/ko.ts | 2 + studio/frontend/src/i18n/locales/pt-br.ts | 2 + studio/frontend/src/i18n/locales/ru.ts | 2 + studio/frontend/src/i18n/locales/zh-CN.ts | 2 + 15 files changed, 227 insertions(+), 10 deletions(-) diff --git a/studio/frontend/src/features/hub/catalog/on-device-folders-dialog.tsx b/studio/frontend/src/features/hub/catalog/on-device-folders-dialog.tsx index 2b0f2c3a8d..bef2f79747 100644 --- a/studio/frontend/src/features/hub/catalog/on-device-folders-dialog.tsx +++ b/studio/frontend/src/features/hub/catalog/on-device-folders-dialog.tsx @@ -23,12 +23,21 @@ import { removeScanFolder, } from "@/features/hub"; import { FolderBrowser } from "@/features/model-picker"; -import { openModelsDir } from "@/features/native-intents"; +import { + openModelsDir, + pickHuggingFaceCacheDir, +} from "@/features/native-intents"; +import { + type HuggingFaceCacheSettings, + loadHuggingFaceCacheSettings, + updateHuggingFaceCacheSettings, +} from "@/features/settings"; import { isTauri } from "@/lib/api-base"; import { toast } from "@/lib/toast"; import { cn } from "@/lib/utils"; import { Delete02Icon, + DownloadCircle01Icon, FileSearchIcon, FolderAddIcon, FolderExportIcon, @@ -49,6 +58,12 @@ function formatError(error: unknown): string { return error instanceof Error ? error.message : String(error); } +function formatFreeSpace(bytes: number | null): string | null { + if (bytes === null || !Number.isFinite(bytes)) return null; + const gb = bytes / 1024 ** 3; + return gb >= 10 ? `${Math.round(gb)} GB free` : `${gb.toFixed(1)} GB free`; +} + export function OnDeviceFoldersDialog({ open, onOpenChange, @@ -68,6 +83,11 @@ export function OnDeviceFoldersDialog({ ); const refreshIdRef = useRef(0); const mutationVersionRef = useRef(0); + const [downloadCache, setDownloadCache] = + useState<HuggingFaceCacheSettings | null>(null); + const [downloadCacheLoaded, setDownloadCacheLoaded] = useState(false); + const [downloadBrowserOpen, setDownloadBrowserOpen] = useState(false); + const [downloadSaving, setDownloadSaving] = useState(false); const sortedFolders = useMemo( () => [...folders].sort((a, b) => a.path.localeCompare(b.path)), @@ -108,10 +128,66 @@ export function OnDeviceFoldersDialog({ return () => window.clearTimeout(timer); }, [open, refreshFolders]); + useEffect(() => { + if (!open) return; + let cancelled = false; + // The dialog stays mounted between opens, so re-arm the flag or a reopen + // shows the previous answer as if it were fresh. + setDownloadCacheLoaded(false); + loadHuggingFaceCacheSettings() + // Indexed locations do not depend on this.

00:00:00 2001 From: Michael Han <107991372+shimmyshimmer@users.noreply.github.com> Date: Tue, 28 Jul 2026 22:16:32 -0700 Subject: [PATCH 213/227] Studio: make the sidebar width draggable (#7561) * Studio: make the sidebar width draggable The sidebar was locked at 17.5rem. Long chat titles truncated early with no way to trade content width for sidebar width. Adds a drag handle on the sidebar edge. Drag to resize between 264px and 480px (also capped at 40% of the window), click to collapse or expand, arrow keys to nudge, Home to restore the default. The width persists in localStorage next to the existing pin flag and syncs across tabs. Dragging in stops at the minimum rather than collapsing, so an overshoot while resizing cannot snap the sidebar shut. The minimum is set by the header: the logo lockup and the search and collapse buttons need ~258px. The wordmark now truncates instead of letting the search icon ride over the logo when the UI font scale pushes the lockup wider. Resizing relayouts the whole shell, so the live width is painted straight to the wrapper's custom property once per animation frame instead of on every pointermove, and only committed to the store on release. * Studio: address review on the draggable sidebar Four fixes from the review: Re-clamp on viewport change. The 40% window cap was only evaluated on load and on an explicit set, so a stored 480px stayed 480px after the window narrowed. The store now keeps the preference whole and derives an effective width from it, recomputed on resize, so narrowing shrinks the sidebar and widening restores the preference instead of discarding it. Keep the DOM and the store in step when a drag does not commit. On pointercancel, and on a collapsed-rail drag that never reached the minimum, the live width was left painted on the wrapper without being stored. Since the provider does not re-render, React never rewrote the property and the next expand could render at the rail's 48px. Drag end now hands the property back to the committed value; a commit re-renders with the new width. Feed the resized width to the custom titlebar. WindowTitlebar sits outside the sidebar wrapper so it cannot inherit --sidebar-width, and it was positioning its seam and drag region from a fixed 17.5rem. It reads the same store now. Mirror the handle for side="right". Placement, cursor, tooltip side and the pointer delta all follow the configured side. Measuring the rail from the sidebar container makes the start width side-agnostic too. Adds unit tests for the clamp, including the viewport cap and the floor winning when 40% falls below it. * Studio: keyboard, aria and titlebar fixes for the sidebar edge Three more from review, and the handle is extracted so the run settings panel can reuse it. Keyboard activation. The handle advertises collapse and expand in its label, but that only ran from pointer-up, and a button's synthesized click is swallowed by the tooltip trigger. Enter and Space now toggle, and the outward arrow reopens a collapsed rail rather than returning early, so a focused handle is not a dead end. Announced maximum. aria-valuemax was the absolute 480 even when the 40% viewport cap put the real limit lower, so a screen reader offered adjustment that could not happen. The store now exposes the effective maximum and recomputes it on resize. Titlebar during a drag. The custom titlebar reads the committed store value, so its seam sat still while the sidebar moved. The drag now mirrors the live width onto the root for it to read, and clears it on release. The drag mechanics move to PanelResizeHandle and the store to a createPanelWidthStore factory. Behaviour is unchanged; both exist so the run settings panel gets the same edge without a second copy. * Studio: keep the stored width when a drag is viewport-capped Dragging outward while the 40% cap is active committed the capped value, so a 480px preference became 320px on a narrow window and never came back when the window widened again. The drag now commits what the pointer asked for rather than what was painted. setWidth still clamps to the absolute range, so a deliberate inward drag is honoured as before; only the capped case stops writing a smaller preference than the user chose. * Studio: review fixes for the panel resize handle Five more from review. Stale width after a resize with nothing mounted. With no subscribers there is no resize listener, so a resize on /login or /onboarding left the cached width and cap stale, and returning to the app restored the old width past the viewport cap. The store now recomputes when a subscriber attaches. Capped outward drags no longer lower the stored preference. The drag starts from the effective width, so with 480 stored in a capped window a small outward pull committed a smaller number and discarded the preference for good. The commit and the outward arrow now leave it alone when the panel is already pinned at the cap. A deliberate inward drag still commits. Keyboard focus was invisible. The app zeroes the native outline on buttons, so a tabbed handle showed nothing at all. It now paints its line on focus-visible and opens the hint. Collapsed aria. The separator reported 264 as its current value while the rail renders at 48 and may restore to something else entirely. The range attributes are dropped when collapsed, leaving the label to describe it. Localised copy. The tooltip is visible text and was hardcoded English in all eleven locales. The strings are props now, supplied through the translation layer, with keys added across every locale. * Studio: support click activation and fix collapsed role Two more from review. Switch and voice control activate a control by dispatching a bare click with no pointer or key events. Everything here hung off pointer-up or keydown, so those users could not toggle the panel at all. There is now a click path, guarded so the click the browser sends after a real pointer release does not toggle a second time. The guard is set when any sequence ends, not only on release: a cancelled drag also ends without a toggle, and its click would otherwise collapse the panel. The suite caught that on the first attempt. A focusable separator is an adjustable widget and needs a current value. Dropping the range attributes while collapsed left an invalid range control, so it reports as a button when closed and a separator with a value when open. * Studio: only suppress the click after a real pointer sequence endDrag doubles as the effect cleanup, so setting the guard there unconditionally swallowed the first click from switch or voice control when no drag had happened. It now only arms after a sequence that actually started, whether it ended in a release or a cancel. * Studio: do not arm the click guard on keyboard toggles preventDefault cancels the native synthesized click, so nothing followed to guard against and the flag stayed set. The next switch or voice activation was then read as a duplicate and ignored. * Make the resize handle click guard self-healing A canceled drag emits no compatibility click, so the boolean guard stayed armed and swallowed the next click from a switch or voice control. Record when the pointer sequence ended instead and ignore only a click that lands inside the browser's compatibility window. * Clear the stored sidebar width on preference reset Reset all local preferences dropped every other UI key but left sidebar_width, so the reload restored the old width instead of the default. * Guard that persisted panel widths stay in the reset list * Tighten the sidebar header actions and lower the width floor The search and collapse buttons carried 8px of padding each side of a 16px icon, so the pair read as one wide block. Narrow them to 28px and close the gap to 1px, which brings the glyphs from 18px apart to 13px. That frees room in the header lockup, so the drag floor drops from 264px to 260px. 260 is the narrowest width that leaves the wordmark unclipped in Firefox, which renders it ~3px wider than Chromium and WebKit. --- .../frontend/src/components/app-sidebar.tsx | 16 +- .../src/components/tauri/window-titlebar.tsx | 7 +- .../src/components/ui/panel-resize-handle.tsx | 317 ++++++++++++++++++ studio/frontend/src/components/ui/sidebar.tsx | 86 ++++- .../features/settings/tabs/general-tab.tsx | 1 + studio/frontend/src/hooks/use-panel-width.ts | 138 ++++++++ .../frontend/src/hooks/use-sidebar-width.ts | 21 ++ studio/frontend/src/i18n/locales/ar.ts | 8 + studio/frontend/src/i18n/locales/de.ts | 8 + studio/frontend/src/i18n/locales/en.ts | 8 + studio/frontend/src/i18n/locales/es.ts | 8 + studio/frontend/src/i18n/locales/fr.ts | 8 + studio/frontend/src/i18n/locales/hi.ts | 8 + studio/frontend/src/i18n/locales/ja.ts | 8 + studio/frontend/src/i18n/locales/ko.ts | 8 + studio/frontend/src/i18n/locales/pt-br.ts | 8 + studio/frontend/src/i18n/locales/ru.ts | 8 + studio/frontend/src/i18n/locales/zh-CN.ts | 8 + studio/frontend/src/index.css | 16 + studio/frontend/tests/sidebar-width.test.ts | 72 ++++ 20 files changed, 751 insertions(+), 11 deletions(-) create mode 100644 studio/frontend/src/components/ui/panel-resize-handle.tsx create mode 100644 studio/frontend/src/hooks/use-panel-width.ts create mode 100644 studio/frontend/src/hooks/use-sidebar-width.ts create mode 100644 studio/frontend/tests/sidebar-width.test.ts diff --git a/studio/frontend/src/components/app-sidebar.tsx b/studio/frontend/src/components/app-sidebar.tsx index d263a6a739..849460dc7d 100644 --- a/studio/frontend/src/components/app-sidebar.tsx +++ b/studio/frontend/src/components/app-sidebar.tsx @@ -1226,7 +1226,9 @@ export function AppSidebar() { openNewChat(null);

Its default healthz_timeout_s of 180 was the only recorded expectation. scripts/profile_startup.py breaks a launch into phases: import cost via python -X importtime in a subprocess (top cumulative contributors), process spawn to first output, and spawn to /healthz 200, over N repeats with median and p90. First numbers on Linux: importing the backend module costs 5.7 to 6.6 seconds before the server can even bind, and it dominates everything else. That is eager module-level imports pulled in by the routes package, not the hardware detection I first suspected: utils.hardware is 23ms and does not pull torch. --max-healthz-seconds exists so a budget can be enforced once per-platform numbers are agreed. It is not wired into a gate yet, deliberately: a threshold picked before the data is in would either be meaningless or flaky. * [pre-commit.ci] auto fixes from pre-commit.com hooks for more information, see https://pre-commit.ci * Profile the code under test, and let the profile fail Both installer calls omitted --local, so every phase measured the published PyPI backend and could not move when a PR edits main.py, run.py or routes. t_first_byte was a dead local, advertised in the docstring but never returned, and the reader could deadlock once the child filled the pipe. A failed launch and an impossible budget both produced a warning and exit 0, and the importtime parse reported the largest cumulative row, which is site, not main, so a raising import published a number as success. Pin the controller to the profiled venv's interpreter. * Stop the startup summary hiding failed launches The aggregates cover only the runs that reached healthz, so two dead launches and one fast one rendered as a normal fast startup, and an all-failed phase printed nothing at all. With continue-on-error and no budget wired, that summary is the only thing anyone sees. Say how many launches the number is made of, and say so explicitly when none came up. * Reject --repeats below 1 range(0) launches nothing, so the empty runs list reached the budget check as "no healthz measurement", warned and exited 0: a gate that cannot fail. The value comes straight from a dispatch input, so reject it loudly instead. * Run the startup profile when the imported startup tree changes The path filter listed main.py, run.py and routes/**, but the graph the profiler measures is far wider: main.py imports auth, core, hub, loggers, models, picker and utils at module scope, and routes/models.py imports utils.utils and utils.hidden_models. A change to any of those moved `import main` without ever running this job, so the regressions the workflow exists to catch went unmeasured. Cover studio/backend/** (tests excluded) and unsloth_cli/**, since the launch phase spawns `unsloth studio --api-only` and the CLI is on the process-to-healthz path. * Read the labelled main row and kill the Windows launcher tree total_seconds took by_cum[0], the largest cumulative row in -X importtime output. That output also carries the interpreter's own startup graph (site, encodings, whatever a venv sitecustomize pulls in), which is not part of import main, and the two are not ordered by construction. With a trivial main the old code reported site's 0.027s as "import main" while main actually cost 0.000249s. Today's backend dwarfs site so the published figures are unchanged, but the headline number must not silently become another module's cost once the backend imports get optimized, so read the row named main. profile_launch spawned Scripts/unsloth.exe on Windows. A pip console-script .exe is a distlib launcher stub that CreateProcess's the venv python and waits, so terminate() reaped the stub and left the backend holding the inherited stdout handle: the reader thread never saw EOF and burned the full 10s join, and with --repeats each iteration stranded another server on the shared UNSLOTH_STUDIO_HOME. Walk the tree with taskkill /T, matching the cleanup in unsloth_cli/commands/start.py and unsloth/dataprep/synthetic.py. * [pre-commit.ci] auto fixes from pre-commit.com hooks for more information, see https://pre-commit.ci * Fail the startup budget when nothing was measured and fall back when taskkill fails * Trigger on installer inputs and harden the startup gate tests * Tighten comments in the startup profiler and its workflow * Trigger the startup profile on the Studio setup scripts install.sh --local runs the checkout's studio/setup.sh, install.ps1 reaches studio/setup.ps1 through the editable install, and both call install_python_stack.py, which decides the dependency set that gets imported. Editing any of them could change startup time with no measurement taken. * Shorten the startup profiler comments Comments and docstrings only. * Reject non-finite startup budgets and profile when the desktop argv changes --max-healthz-seconds nan or inf parses as a float but compares False against any median, so the gate reported success without bounding anything. Require a finite value. The profiler hardcodes the argv that process.rs::backend_args builds, but that file was not in the trigger paths, so a change to the desktop launch command scheduled no measurement. Add it, and anchor the two argv lists with a test. * [pre-commit.ci] auto fixes from pre-commit.com hooks for more information, see https://pre-commit.ci --------- Co-authored-by: pre-commit-ci[bot] <66853113+pre-commit-ci[bot]@users.noreply.github.com> Co-authored-by: danielhanchen <unslothai@gmail.com> --- .github/workflows/startup-profile-ci.yml | 156 ++++++++++ scripts/profile_startup.py | 377 +++++++++++++++++++++++ tests/test_profile_startup_gate.py | 243 +++++++++++++++ 3 files changed, 776 insertions(+) create mode 100644 .github/workflows/startup-profile-ci.yml create mode 100644 scripts/profile_startup.py create mode 100644 tests/test_profile_startup_gate.py diff --git a/.github/workflows/startup-profile-ci.yml b/.github/workflows/startup-profile-ci.yml new file mode 100644 index 0000000000..fbde99836d --- /dev/null +++ b/.github/workflows/startup-profile-ci.yml @@ -0,0 +1,156 @@ +# SPDX-License-Identifier: AGPL-3.0-only +# Copyright 2026-present the Unsloth AI Inc. team.

Neither holds on the consumer path: the unsloth-zoo git+https URL is only used under STUDIO_LOCAL_INSTALL, node is a pinned nodejs.org prebuilt that never touches system npm, and the frontend lockfile has no VCS dependencies. It stays fatal for --local, where it really is needed. Ensure-VCRedist was winget-only, so on hosts without winget (LTSC, Server, managed corporate images) it silently did nothing while the install reported success, and torch then failed to import on a missing VCRUNTIME140.dll. Adds a direct aka.ms/vs/17/release/vc_redist.<arch>.exe download with /quiet /norestart, accepting exit codes 0 and 3010. The redistributable stays required: it is the runtime the prebuilt llama-server and torch link against, not the MSVC compiler, which is already detection-only. Windows on ARM has no PyTorch at all. Measured with uv against download.pytorch.org/whl/cpu and PyPI for aarch64-pc-windows-msvc / cp313: torch, torchvision and torchaudio all resolve to nothing, wheels exist only for win_amd64 and the manylinux targets. The installer burned three uv retries on an unsatisfiable resolution and reported a bare 'Failed to install PyTorch (exit code 1)'. Now it says what is actually wrong and points at --no-torch, which works because llama.cpp does publish windows-arm64-cpu. install_node_prebuilt.py hit '[WinError 5] Access is denied' on os.replace of the freshly extracted directory during a FRESH install, which is a scanner or indexer holding handles for a moment. Retries only winerror 5, 32 and 145 with capped exponential backoff; any other OSError still raises immediately. * [pre-commit.ci] auto fixes from pre-commit.com hooks for more information, see https://pre-commit.ci * Give the ARM64 dead end a recovery that works for web installs The only remedy printed was .\install.ps1 --no-torch, but the documented path is irm | iex, where no file exists and flags cannot be forwarded. Name the env var the script already honours at line 145. * Windows on ARM: drop torchaudio, do not abort the install The fail-fast was based on a wrong premise. Counted against download.pytorch.org/whl/cpu: torch has 42 win_arm64 wheels and torchvision 60; only torchaudio has none. PyTorch has shipped Arm-native Windows builds since April 2025, so aborting blocked a platform that mostly works. Drop the one unsatisfiable pin instead. Decide from the interpreter uv will resolve for, not the PowerShell host: an x64 CPython under emulation gets working win_amd64 wheels on an ARM64 box, and powershell.exe inherits PROCESSOR_ARCHITECTURE from its parent. * Carry the ARM64 torchaudio omission into studio setup Dropping it from the first PyTorch command was not enough: install.ps1 then runs studio setup with SKIP_STUDIO_BASE=1 and setup.ps1 reinstalls the bare trio from the CPU index, so the ARM64 path still aborted. Apply the same interpreter-based test there. An unreadable platform keeps the full trio. * Build the torch spec list outside the verbose branch The ARM64 guard landed inside `if ($script:UnslothVerbose)`, so on the default path $_torchTrio was never assigned and the splat expanded to nothing: uv ran as `uv pip install --index-url ...` with no package, exit 2, straight to Exit-SetupFailure. That broke the ordinary Windows install. Hoist it above the branch and use substep, which prints on both paths. Realign the two parity guards to the splat form; they asserted the pre-refactor literal command and were the actual cause of the red parity legs. Both halves are still checked: the bounded list is built, and it reaches the install. * Tighten the comments on the Windows install path * Windows install: honour the ARM64 torchaudio skip everywhere and keep git for source builds Hoist the venv-interpreter platform probe above every torch branch in studio/setup.ps1 so the win_arm64 torchaudio omission applies to the ROCm, CPU and CUDA/custom paths. A pinned index whose leaf is not cpu routed an ARM64 host into the CUDA/custom branch, which still asked for torchaudio. Require git again when a llama.cpp source build is opted into up front (UNSLOTH_LLAMA_FORCE_COMPILE, UNSLOTH_LLAMA_PR / PR_FORCE, a non-upstream source). Those paths git clone in phase 4, so setup used to report git as not required, install the build toolchain, then fail at the clone. A local llama.cpp dir overrides them, and the automatic source fallback after a failed prebuilt download stays non-fatal. Also tighten the comments across the changed install paths. * Install the x64 VC++ runtime unconditionally in the direct-download fallback The winget branch always installs Microsoft.VCRedist.2015+.x64, but the direct-download fallback picked the package from PROCESSOR_ARCHITECTURE, which reports the architecture of the running PowerShell process rather than the interpreter that will load the DLLs. Find-CompatiblePython in install.ps1 selects an interpreter on version and non-Conda status alone, with no architecture predicate, so a native ARM64 shell can settle on an emulated x64 Python whose win_amd64 torch and prebuilt llama-server need the x64 runtime, while the fallback had just installed the ARM64-only package. Ensure-VCRedist also runs well before the venv exists, so the interpreter cannot be probed at that point. Microsoft ships the x64 redistributable as an Arm64X superset that carries both ARM64 and x64 binaries, so it is correct on both machines and the manual instruction printed on failure already pointed at it. * Windows on ARM: prefer an x64 Python interpreter An ARM64 host cannot complete the install with a native ARM64 interpreter. pyarrow, pulled in by unsloth -> datasets, has never published a win_arm64 wheel on any version, and neither has hf-transfer, a direct dependency. Both therefore fall back to a source build: pyarrow dies in scikit-build-core CMake configuration and hf-transfer dies in openssl-sys for want of perl, several minutes into a run that looked healthy. torch and torchvision are not the problem, they have win_arm64 wheels and install fine. Windows 11 on ARM runs x64 binaries under emulation and both packages ship win_amd64 wheels, so an x64 interpreter installs cleanly. Find-CompatiblePython accepted an interpreter on version and non-Conda status alone. It now ranks candidates by architecture on ARM64 hosts and returns an x64 one when present, asking each interpreter for its own sysconfig.get_platform() rather than guessing from its path. Host architecture comes from PROCESSOR_ARCHITEW6432 and OSArchitecture as well as PROCESSOR_ARCHITECTURE, which describes only the current process and reads AMD64 in an emulated shell. This is a preference, not a requirement. If only ARM64 is found, x64 is bootstrapped through winget --architecture x64 or the python.org fallback, and if neither works the installer names pyarrow and hf-transfer up front instead of failing later on a CMake or Rust error. The ARM64 torchaudio skip stays live for that path. Non-ARM hosts return on the first match exactly as before, with no extra interpreter probing. * Windows install: three correctness fixes on the ARM64 and git-less paths Ensure-VCRedist never reached its x64 download on an ARM64 machine that already had the arm64 redistributable: Test-VCRedistInstalled accepted System32\vcruntime140_1.dll regardless of architecture, and there that file can be the pure-ARM64 package. An ARM64 PE cannot load into an emulated x64 process, so the x64 Python this branch now prefers would have been left without a usable runtime. The x64 registry entry is the only x64-specific proof, and Microsoft registers Runtimes\{x86|x64|arm64} per architecture, so vc_redist.x64.exe still writes Runtimes\x64 on an ARM64 host and the check cannot loop. The DLL probe stays for x64 hosts. Phase 1 demanded git for any non-blank UNSLOTH_LLAMA_PR_FORCE, but the promotion that actually turns it into a source build requires a positive integer, so PR_FORCE=0 or a non-numeric value aborted a git-less consumer install for a build that never runs. Both sites now use the same predicate. The automatic fallback after a failed prebuilt llama.cpp download reached git clone with no git check anywhere in between, and Invoke-SetupCommand returns 0 for a command-not-found, so a git-less host did not stop there: it continued into an empty directory and reported a cmake configure failure instead. Git is now resolved where the source build is decided, with a last winget attempt, and a missing git degrades exactly like a missing cmake rather than aborting, since the opt-in source triggers already required git in Phase 1. Also tightened the comments across the changed Windows install code, keeping the reasons on the guards that prevent a specific failure. * Rank ARM64 Python candidates by minor version before architecture The x64 preference filtered the whole candidate list on architecture, which outranks the version preference the candidates were collected in. With UNSLOTH_PYTHON=3.12 on a Windows ARM64 box holding an ARM64 3.12 and an x64 3.13, it returned the x64 3.13: the explicit pin was silently broken, and because a x64 interpreter was found the caller never ran Install-X64Python to fetch an x64 3.12. With no pin it was worse still, since an x64 3.11 outranked a newer ARM64 3.13 and defeated the newest-first fallback. Walk $minors in order and take the x64 build of the best minor available, falling back to that minor's ARM64 build so the caller bootstraps x64 for the version actually requested. x64 still wins within a minor, and non-ARM hosts are untouched. * Windows install: see every registered Python, order git before the toolchain Find-CompatiblePython only ever probed `py -3.X`, which runs the launcher's preferred build for that minor. On an ARM64 box that is the native ARM64 interpreter, so a same-minor x64 install that is registered with the launcher but neither preferred nor on PATH never became a candidate. The x64 preference then lost to ARM64, and Install-X64Python re-downloaded an x64 CPython that was already on the machine; when that download is unavailable the install continues on ARM64 and source-builds pyarrow and hf-transfer, which publish no win_arm64 wheels. Enumerate `py -0p` on ARM64 hosts and probe each listed path. The `-3.12-64` suffix cannot be used for this: it has meant "not 32-bit" since 3.11 and does not distinguish arm64 from amd64. studio/setup.ps1 ran Ensure-BuildToolsForLlamaSourceBuild before checking git in Phase 4. That helper calls Exit-SetupFailure when Visual Studio Build Tools cannot be installed, so on a clean no-winget box the git degraded path added by this PR was unreachable and a standalone update aborted instead of finishing in limited mode; where winget does exist it spent a multi-GB Build Tools download on a clone that could never run. Check and install git first, skip the toolchain helper when git is still missing, and report the git branch before the cmake branch so the message names the real cause. _swap_into_place retried the forward rename for about 16 seconds but rolled back with a bare os.replace. A scanner holding the backup for the same WinError 5/32 then left no install_dir at all and stranded the working runtime in .old-*, and its exception replaced the original failure. The rollback now uses the same backoff and logs instead of masking the error it is recovering from. * Installer: use an already installed x64 Python on ARM64 when none can be downloaded Find-CompatiblePython ranks x64 within one minor and returns the native build when that minor is ARM64-only, leaving Install-X64Python to bootstrap x64. On an offline or winget-less box that bootstrap fails, and the retry went through the same resolver, so an x64 build of a lower-priority supported minor already on the machine was never picked up and setup continued on ARM64 Python, where pyarrow and hf-transfer have no wheels. Add an -X64Only mode that returns the best installed x64 interpreter or nothing, and call it as the last resort in Install-X64Python. The version-first preference is unchanged: x64 of the requested minor is still bootstrapped first. * [pre-commit.ci] auto fixes from pre-commit.com hooks for more information, see https://pre-commit.ci * Tighten comments in the Windows ARM64 installer changes * Setup: require Git for a source build behind an unbuilt local llama.cpp dir UNSLOTH_LOCAL_LLAMA_CPP_DIR only overrides the source-build opt-ins once the directory holds a reusable llama-server.exe. Pointing it at the canonical install location with nothing built there falls through to the normal install, so the Phase 1 gate now probes the same layout candidates as the Phase 4 reuse check before dropping the requirement. * Setup: require Git when UNSLOTH_LLAMA_TAG=master forces a source build * Tighten comments in the Windows installer changes * Setup: negotiate TLS 1.2 for the direct VC++ runtime download --------- Co-authored-by: pre-commit-ci[bot] <66853113+pre-commit-ci[bot]@users.noreply.github.com> Co-authored-by: danielhanchen <unslothai@gmail.com> --- install.ps1 | 146 +++++++++++++- studio/install_node_prebuilt.py | 43 ++++- studio/setup.ps1 | 182 ++++++++++++++++-- tests/python/test_cross_platform_parity.py | 24 ++- .../test_windows_arm64_python_choice.py | 143 ++++++++++++++ tests/python/test_windows_git_gate.py | 117 +++++++++++ .../test_windows_vcredist_download_tls.py | 80 ++++++++ .../test_install_node_prebuilt_logic.py | 91 +++++++++ 8 files changed, 791 insertions(+), 35 deletions(-) create mode 100644 tests/python/test_windows_arm64_python_choice.py create mode 100644 tests/python/test_windows_git_gate.py create mode 100644 tests/python/test_windows_vcredist_download_tls.py diff --git a/install.ps1 b/install.ps1 index 0b06cb3ea1..5b205df96d 100644 --- a/install.ps1 +++ b/install.ps1 @@ -57,6 +57,26 @@ function Install-UnslothStudio { } } + # Machine arch; Get-TauriDiagArch above reports the process.

It now uses the same drag handle as the sidebar, on its left edge, between 248px and 560px and capped at 40% of the window. The width persists and syncs across tabs. Reuses PanelResizeHandle and createPanelWidthStore, so behaviour matches the sidebar exactly. The panel width key joins the preference reset list. The system prompt overflow check now runs off a ResizeObserver attached through a callback ref. A drag changes the width through a custom property without re-rendering, and the collapsible section unmounts the textarea, so a stored observer would miss both. --- .../src/features/chat/chat-settings-sheet.tsx | 100 +++++++++++++++--- .../features/settings/tabs/general-tab.tsx | 1 + .../src/hooks/use-chat-settings-width.ts | 20 ++++ studio/frontend/src/index.css | 3 +- studio/frontend/tests/sidebar-width.test.ts | 2 +- 5 files changed, 108 insertions(+), 18 deletions(-) create mode 100644 studio/frontend/src/hooks/use-chat-settings-width.ts diff --git a/studio/frontend/src/features/chat/chat-settings-sheet.tsx b/studio/frontend/src/features/chat/chat-settings-sheet.tsx index 6070bd2e40..fd41e558f9 100644 --- a/studio/frontend/src/features/chat/chat-settings-sheet.tsx +++ b/studio/frontend/src/features/chat/chat-settings-sheet.tsx @@ -18,6 +18,7 @@ import { DropdownMenuTrigger, } from "@/components/ui/dropdown-menu"; import { InfoHint } from "@/components/ui/info-hint"; +import { PanelResizeHandle } from "@/components/ui/panel-resize-handle"; import { InputGroup, InputGroupAddon, @@ -44,7 +45,13 @@ import { Tooltip, TooltipContent } from "@/components/ui/tooltip"; import { NumericValueInput, snapToStep } from "@/features/model-picker"; import { RetrievalSettingsSection } from "@/features/rag"; import { useLlamaUpdateCheck } from "@/hooks/use-llama-update-check"; +import { + CHAT_SETTINGS_WIDTH_MIN, + clampChatSettingsWidth, + useChatSettingsWidth, +} from "@/hooks/use-chat-settings-width"; import { useIsMobile } from "@/hooks/use-mobile"; +import { useT } from "@/i18n"; import { ChevronDownStandardIcon } from "@/lib/chevron-icons"; import { toast } from "@/lib/toast"; import { cn } from "@/lib/utils"; @@ -52,7 +59,7 @@ import { Edit03Icon, LayoutAlignRightIcon } from "@hugeicons/core-free-icons"; import { HugeiconsIcon } from "@hugeicons/react"; import { Braces, ChevronDown, ExternalLink } from "lucide-react"; import { Tooltip as TooltipPrimitive } from "radix-ui"; -import { Fragment, type ReactNode } from "react"; +import { type CSSProperties, Fragment, type ReactNode } from "react"; import { useCallback, useEffect, useMemo, useRef, useState } from "react"; import { OpenAICodeExecSection } from "./components/openai-code-exec-section"; import { PermissionModeDropdown } from "./permission-mode-select"; @@ -363,6 +370,15 @@ export function ChatSettingsPanel({ onExternalProviderChange, externalProviderType = null, }: ChatSettingsPanelProps) { + const asideRef = useRef<HTMLElement>(null); + const t = useT(); + const { + width: settingsWidth, + max: settingsMax, + stored: settingsStored, + setWidth: setSettingsWidth, + resetWidth: resetSettingsWidth, + } = useChatSettingsWidth(); // Local models show every knob; providerCapabilities is only consulted when // isExternalModel.

The Windows Studio smoke jobs run under bash and read the file with OLD=$(cat ...), which strips the LF but leaves the CR attached, so the credential goes into the login body as "<secret>\r" and the request fails. Write bytes in the backend and pin newline in the CLI so the file is "<secret>\n" on every platform. generate_bootstrap_password() also returned early on an existing file, so upgraded installs kept the original problem; it now rewrites anything that isn't already exactly "<secret>\n", best-effort so a read-only auth dir cannot fail startup. The raw test assertions used read_text(), which decodes CRLF back to "\n" and would have stayed green on Windows. They read bytes now. * [pre-commit.ci] auto fixes from pre-commit.com hooks for more information, see https://pre-commit.ci * Run the newline migration on the path upgrades actually take ensure_default_admin() short-circuits to _load_bootstrap_password() once the admin row exists, so the normalisation added in the previous commit sat on generate_bootstrap_password(), which only fresh installs reach. An upgraded install kept its newline-less file. Both readers now share _read_persisted_bootstrap_password(). Make the write atomic while it is here: it can now rewrite a live file, and a partial write would destroy the only plaintext copy of the recovery credential. Same mkstemp plus os.replace shape the CLI writer already uses. Tests cover the upgrade path through ensure_default_admin(), a well-formed file not being rewritten on every start, a failing migration not blocking startup, and the atomic replace. * [pre-commit.ci] auto fixes from pre-commit.com hooks for more information, see https://pre-commit.ci * Normalise the bootstrap file in place so a cleared credential stays cleared The rename-based rewrite could recreate the file: if a password change ran clear_bootstrap_password(), or the CLI cleanup deleted it, between the read and the write, os.replace put the revoked plaintext back on disk, where a later auth.db reset would re-seed it. Open the existing file without O_CREAT instead, so a deleted file cannot be resurrected, and re-check the contents through that descriptor so an in-place truncation or a rotated credential is not overwritten either. That gives up the atomic rename, so the in-place path is restricted to trailing-whitespace fixes. Every partial state is then the secret plus leftover whitespace, which still strips to the same credential. Files with leading whitespace are left alone; every reader strips, so they keep working. Creation still goes through the atomic writer. * Open the bootstrap file in binary mode and finish the write Three defects in the in-place normalisation, all on the Windows upgrade path. os.open does not add O_BINARY on Windows and CPython never changes the CRT default of _O_TEXT, so the descriptor was in text mode: os.write turned the LF straight back into CRLF and ftruncate then cut the LF off, leaving "<secret>\r". That is the bug this PR exists to fix, reintroduced by the migration itself, and it is a fixed point that never converges. os.read translates in reverse too, so a genuinely CRLF file failed verification and was silently skipped. os.write may return having written fewer bytes than asked; ftruncate would then NUL-extend the credential so it no longer matched the hash in auth.db. os.fchmod only reached Windows in 3.13 and AttributeError is not OSError, so on 3.9 to 3.12 it escaped both handlers and aborted the first start after upgrade. * Make the bootstrap normalisation append-only clear_bootstrap_password() falls back to truncating the file through its own descriptor when the unlink fails, which is what happens on Windows while this one is open. That truncation could land after the equality check and before the write, so the rewrite put the revoked plaintext back. Append a single LF instead, and only to a file that is exactly the credential. An append cannot restore a revoked secret: over a cleared file the result is a lone newline, which strips to empty and reads back as no bootstrap password. Releases before the newline wrote the password with no terminator at all, so that is the only shape in the wild; anything else is left alone and keeps working because every reader strips. Never truncating also removes the short-write NUL-fill hazard entirely, so the write loop is gone. O_BINARY stays: without it Windows would turn the appended LF into CRLF. * [pre-commit.ci] auto fixes from pre-commit.com hooks for more information, see https://pre-commit.ci * Fix a typo in a bootstrap normalisation test name * Tighten the bootstrap newline comments --------- Co-authored-by: pre-commit-ci[bot] <66853113+pre-commit-ci[bot]@users.noreply.github.com> Co-authored-by: Daniel Han <danielhanchen@gmail.com> Co-authored-by: danielhanchen <unslothai@gmail.com> --- studio/backend/auth/storage.py | 125 ++++++++-- studio/backend/tests/test_desktop_auth.py | 217 +++++++++++++++++- unsloth_cli/commands/studio.py | 7 +- .../tests/test_studio_password_prompt.py | 35 ++- 4 files changed, 357 insertions(+), 27 deletions(-) diff --git a/studio/backend/auth/storage.py b/studio/backend/auth/storage.py index 35135b21eb..9702827725 100644 --- a/studio/backend/auth/storage.py +++ b/studio/backend/auth/storage.py @@ -9,6 +9,7 @@ import ipaddress import os import secrets import sqlite3 +import tempfile import threading from datetime import datetime, timezone from typing import Optional, Tuple @@ -30,6 +31,97 @@ _BOOTSTRAP_PW_PATH = DB_PATH.parent / ".bootstrap_password" _bootstrap_password: Optional[str] = None +def _bootstrap_file_bytes(password: str) -> bytes: + """Exact on-disk form: the secret plus one LF. + + Bytes, not text: text mode writes CRLF on Windows, and `$(cat ...)` strips + the LF but leaves the CR attached to the credential. + """ + return (password + "\n").encode("utf-8") + + +def _persist_bootstrap_password(password: str) -> None: + """Atomically write the bootstrap password 0600, LF terminated on every OS. + + A partial write would destroy the only plaintext recovery credential. + """ + fd, tmp_name = tempfile.mkstemp( + prefix = f".{_BOOTSTRAP_PW_PATH.name}.", dir = _BOOTSTRAP_PW_PATH.parent + ) + try: + with os.fdopen(fd, "wb") as f: + f.write(_bootstrap_file_bytes(password)) + try: + os.chmod(tmp_name, 0o600) + except OSError: + pass + os.replace(tmp_name, _BOOTSTRAP_PW_PATH) + except BaseException: + try: + os.unlink(tmp_name) + except OSError: + pass + raise + + +def _normalise_bootstrap_file(raw: bytes, password: str) -> None: + """Append the LF a pre-newline release left off. + + Append-only, and only when the file is exactly the credential: + clear_bootstrap_password() may unlink or (when unlink fails, notably on + Windows while this descriptor is open) truncate through another descriptor + after we read, so a rewrite could restore revoked plaintext.

Four had been failing on main unnoticed. Two were stale rather than broken code: - test_studio_default_exposes_parallel_option pinned the plain --parallel default to 1, but #7455 deliberately moved _PARALLEL_DEFAULT_PLAIN to 4 so a new chat does not queue behind the previous one. Assert against the constant so the two cannot drift again. - test_reexec_forwards_api_only expected --secure --api-only to re-exec. The pre-exposure gate now refuses that combination, because api-only serves no login page and the bootstrap deadline does not apply, so a seeded password could never be changed. Drop the case and assert the refusal instead. Two only passed when a built frontend dist happened to be present, which it is not in a fresh clone or on a runner. Both reach a public-launch path where the missing-dist gate exits first, so they never got to the backend check and the run_server call they are about. Stub _find_frontend_dist the way their siblings already do. Own step rather than folding into the tests/ discovery: pyproject's testpaths is tests/, and this suite needs no PYTHONPATH or CUDA spoof, importing neither unsloth nor torch. Its deps are already installed by the job (pydantic and uvicorn, which brings click, via studio.txt; pyyaml explicitly). --- .github/workflows/studio-backend-ci.yml | 12 +++++++++++ .../tests/test_studio_password_prompt.py | 6 ++++++ .../tests/test_studio_run_parallel_flag.py | 20 ++++++++++++++++--- unsloth_cli/tests/test_studio_secure_flag.py | 5 +++++ 4 files changed, 40 insertions(+), 3 deletions(-) diff --git a/.github/workflows/studio-backend-ci.yml b/.github/workflows/studio-backend-ci.yml index ec437e0c32..ae91e99b70 100644 --- a/.github/workflows/studio-backend-ci.yml +++ b/.github/workflows/studio-backend-ci.yml @@ -223,6 +223,18 @@ jobs: tests/studio/test_is_mlx_dispatch_gate.py \ tests/studio/test_xpu_spoof_pipeline.py + - name: CLI tests (unsloth_cli) + # unsloth_cli/tests had no CI at all: `unsloth_cli/**` was only a paths + # trigger and a ruff target, so 673 tests covering the studio launcher, + # the pre-exposure gate and the auth secret writers ran nowhere, and + # four of them had been failing on main unnoticed. + # Own step, not folded into the tests/ discovery above: pyproject's + # testpaths is tests/, and this suite needs no PYTHONPATH or CUDA spoof + # (it self-bootstraps sys.path and imports neither unsloth nor torch). + # Run the whole directory in one invocation; some files in it are + # order-dependent and only pass in a full-directory run. + run: python -m pytest unsloth_cli/tests -q --tb=short + - name: Shell installer tests # Auto-discovered rather than allowlisted.

That module lives under studio/backend, so it only imports once something has put that directory on sys.path, and nothing in either file does. They were relying on test_start.py, which calls ensure_studio_backend_path() and leaks the sys.path entry, or on test_studio_cloudflare_flag.py, which stubs the module.

Every file in unsloth_cli/tests now passes on its own, and the suite is stable across four pytest-randomly seeds. * [pre-commit.ci] auto fixes from pre-commit.com hooks for more information, see https://pre-commit.ci --------- Co-authored-by: pre-commit-ci[bot] <66853113+pre-commit-ci[bot]@users.noreply.github.com> --- .github/workflows/studio-backend-ci.yml | 2 -- unsloth_cli/tests/conftest.py | 26 +++++++++++++++++++ .../tests/test_studio_run_parallel_flag.py | 6 +++-- unsloth_cli/tests/test_studio_secure_flag.py | 2 +- 4 files changed, 31 insertions(+), 5 deletions(-) create mode 100644 unsloth_cli/tests/conftest.py diff --git a/.github/workflows/studio-backend-ci.yml b/.github/workflows/studio-backend-ci.yml index ae91e99b70..dd5efbb299 100644 --- a/.github/workflows/studio-backend-ci.yml +++ b/.github/workflows/studio-backend-ci.yml @@ -231,8 +231,6 @@ jobs: # Own step, not folded into the tests/ discovery above: pyproject's # testpaths is tests/, and this suite needs no PYTHONPATH or CUDA spoof # (it self-bootstraps sys.path and imports neither unsloth nor torch). - # Run the whole directory in one invocation; some files in it are - # order-dependent and only pass in a full-directory run. run: python -m pytest unsloth_cli/tests -q --tb=short - name: Shell installer tests diff --git a/unsloth_cli/tests/conftest.py b/unsloth_cli/tests/conftest.py new file mode 100644 index 0000000000..bb42914e69 --- /dev/null +++ b/unsloth_cli/tests/conftest.py @@ -0,0 +1,26 @@ +# SPDX-License-Identifier: AGPL-3.0-only +# Copyright 2026-present the Unsloth AI Inc. team.

Every call site moved to validate_api_key_with_credential, so the Source lint job's import-hoist gate flagged it as a blocker. The wrapper itself stays in storage.py; test_api_key_expiry.py still exercises it. Make test_run_reexec_forwards_resolved_frontend_on_public_launch compare against str(Path(...)) instead of a POSIX literal. _find_frontend_dist returns a Path, so on Windows the forwarded value is \fake\studio\frontend\dist and the assertion could never pass there.

Each item below is a case where the new code either lost a server the old code could still stop, or stopped something that was not ours. All were reproduced against real Studio servers. studio/backend/run.py - Write the per-port record and the legacy studio.pid independently. They shared one try, so a studio root that could not take a new directory entry left the server recorded nowhere at all and unstoppable from the CLI; the old code still recorded it in studio.pid, which is an overwrite of an existing path and can still succeed. _remove_pid_file now also checks studio.pid when the per-port write failed. - Write the record through a temp file and os.replace. `stop` reads these concurrently and treats a truncated read as a corrupt record. - A failed Windows tasklist probe now means "alive", matching the CLI. Treating it as dead pruned a live server's record and let the next launch fall back past it, which is the orphan this work exists to fix. - Guard the unlink in _own_studio_on_port. Pruning is a courtesy and must not abort startup. - Extract _resolve_port so the requested-port abort is reachable from a test. Deleting that abort previously left the whole suite green. - Keep the plain fallback for api-only callers. The desktop app hardcodes 8888 and documents its reliance on the 8888-8908 range, and it reports a non-zero backend exit to the user as "Server stopped unexpectedly". It reads the bound port back from TAURI_PORT, as `studio run` does from app.state.server_port, so a fallback there is harmless and both servers are still recorded and stoppable. The interactive path prints the requested port, so it still aborts. - isdigit() is not enough to gate int(): a superscript two passes it and the ValueError escaped into every caller of _read_pid_record. unsloth_cli/commands/studio.py - An untimed record no longer cancels a timed one for the same PID. Every current server writes both a timed per-port record and an untimed studio.pid, so the start-time check was inert exactly where it mattered, and after a crash plus a PID reuse `stop` sent SIGTERM to whatever unrelated process had inherited the PID. - Distinguish an unreadable record from an invalid one. A root-owned record, or one caught mid-write, still belongs to a live server, and deleting it stranded that server. - Route every PID-file removal through _unlink_quietly. One undeletable record raised PermissionError and left the remaining live servers running. - Same isdigit()/int() guard as the backend. Tests - The requested-port abort, the recorded bind address, and the api-only fallback are now covered; all three previously survived deletion. - tests/studio/test_studio_pid_file_contract.py pins run.py's filename scheme to the CLI's glob and keeps studio.pid parseable by an older CLI. It lives under tests/studio because unsloth_cli/tests is not run by any workflow. - test_cli_studio_stop_windows.py now checks _signal_stop as well as stop. The kill moved into _signal_stop, so the os.kill(pid, 0) guard passed vacuously. * [pre-commit.ci] auto fixes from pre-commit.com hooks for more information, see https://pre-commit.ci * Studio: let a caller that follows the port keep the fallback, and never take studio.pid from a live server Two problems with keying the own-server abort on api_only. `unsloth studio run` is not the bare-banner path: it stores `app = run_server(...)` and reads `app.state.server_port` back, then uses it for the health wait, the model load and the printed base URL. Gating on api_only aborted it, so starting a second model while the first was up stopped working, where before it landed on the next port and printed the right URL. Replace the proxy with an explicit abort_if_own_studio, defaulting to the old api_only behaviour so the exec'd `run.py` path is unchanged, and have `studio run` opt out. The api_only exemption also reopened the orphan from the other side. _write_pid_file overwrote studio.pid unconditionally, and a pre-upgrade server is recorded there and nowhere else, so an exempt launch falling back past one erased its only record. Take the file over only when it is free, already ours, or held by a dead PID. Also resync _pid_is_studio_backend with the CLI copy: an untimed record next to a timed one carried no information but cancelled the start-time check, which is what let a reused PID be treated as ours. Tests: 51 backend, 26 CLI, 9 under tests/studio. Real Studio servers still abort the bare same-port relaunch, still fall back past a foreign listener, and one `unsloth studio stop` still stops every server in all five scenarios. * Studio: hand over the legacy PID pointer, and fail stop on unreadable records Two follow-ups from review of the previous commit. Only one backend owns studio.pid at a time. When that server exited it deleted the file, so an older CLI, which reads nothing else, could no longer stop a sibling that was still serving. _remove_pid_file now hands the pointer to a live sibling instead of dropping it. _pid_file_entries skipped records it could not read, for instance one written by a server started under sudo. When that was the only record, stop printed "No running Unsloth server found" and exited 0 while the server kept serving. Unreadable records are now reported and make stop exit 1, so a partial stop is never mistaken for a complete one. * [pre-commit.ci] auto fixes from pre-commit.com hooks for more information, see https://pre-commit.ci --------- Co-authored-by: pre-commit-ci[bot] <66853113+pre-commit-ci[bot]@users.noreply.github.com> Co-authored-by: Daniel Han <unslothai@gmail.com> --- studio/backend/run.py | 347 ++++++++++- studio/backend/tests/test_studio_pid_files.py | 568 ++++++++++++++++++ tests/studio/test_cli_studio_stop_windows.py | 16 +- tests/studio/test_studio_pid_file_contract.py | 73 +++ unsloth_cli/commands/studio.py | 230 +++++-- unsloth_cli/tests/test_studio_stop.py | 530 ++++++++++++++++ 6 files changed, 1702 insertions(+), 62 deletions(-) create mode 100644 studio/backend/tests/test_studio_pid_files.py create mode 100644 tests/studio/test_studio_pid_file_contract.py create mode 100644 unsloth_cli/tests/test_studio_stop.py diff --git a/studio/backend/run.py b/studio/backend/run.py index 076a1f851b..2d9e714d90 100644 --- a/studio/backend/run.py +++ b/studio/backend/run.py @@ -10,7 +10,7 @@ import os import sys import time from pathlib import Path -from typing import Optional, Tuple +from typing import NoReturn, Optional, Sequence, Tuple def _fix_torch_cuda_ld_path(): @@ -689,6 +689,33 @@ def _get_pid_on_port(port: int) -> "tuple[int, str] | None": return None +def _bind_addresses(host: str, port: int) -> "set[str]": + """Every address *host* resolves to. `localhost` is both 127.0.0.1 and ::1, and + recording only the first lets a later launch on the other one miss us.""" + import socket + + try: + infos = socket.getaddrinfo(host, port, socket.AF_UNSPEC, socket.SOCK_STREAM) + except OSError: + return {host} + return {info[4][0] for info in infos} or {host} + + +def _addresses_collide(recorded: "str | None", host: str, port: int) -> bool: + """Would a server bound to *recorded* block a bind to *host*? + + *recorded* may list several addresses.

Matches tests/test_gemma_2b_mapper_key.py, which reads the same file, and adds the SPDX header new files in tests/ carry. * Check nested precision dicts in the duplicate key guard The registry nests a per-precision dict ("16" / "8") under 26 entries and mapper.py reads those keys directly, so a duplicate there overwrites the earlier mapping exactly like a top level duplicate. The guard only looked at the top level keys. Walk every dict literal in the registry, count keys per dict so "16" and "8" repeating across sibling entries stay legal, and report the offending line numbers so a failure points straight at the entry. * Tighten comments in the mapper duplicate key guard --------- Co-authored-by: pre-commit-ci[bot] <66853113+pre-commit-ci[bot]@users.noreply.github.com> Co-authored-by: Lee Jackson <130007945+Imagineer99@users.noreply.github.com> Co-authored-by: Daniel Han <danielhanchen@gmail.com> --- tests/test_mapper_no_duplicate_keys.py | 53 ++++++++++++++++++++++++++ unsloth/models/mapper.py | 4 -- 2 files changed, 53 insertions(+), 4 deletions(-) create mode 100644 tests/test_mapper_no_duplicate_keys.py diff --git a/tests/test_mapper_no_duplicate_keys.py b/tests/test_mapper_no_duplicate_keys.py new file mode 100644 index 0000000000..42e49415fd --- /dev/null +++ b/tests/test_mapper_no_duplicate_keys.py @@ -0,0 +1,53 @@ +# SPDX-License-Identifier: AGPL-3.0-only +# Copyright 2026-present the Unsloth AI Inc. team.

Keep punctuation-only tokens in the repeat comparison, so "the value is 5" and "the value is < 5" stay distinct, and compare content-word sequences instead of a similarity ratio: any ratio is length-dependent, so one corrected token in a 54-token plan still scored 0.98 and cost the model its remaining nudge. * [pre-commit.ci] auto fixes from pre-commit.com hooks for more information, see https://pre-commit.ci * studio: tighten comments in the plan-without-action re-prompt path * studio: keep a forced retry that pivots from a plan to an answer The obligation-plan branch discarded the whole turn, so a retry such as "I should call web_search, but the answer is Tokyo." reached the user as nothing at all. Suppress the plan only when nothing follows it: a pivot after the match keeps the output, and _FINAL_ANSWER_SIGNAL now recognises "the answer is" and "to summarise" alongside "answer:". Leaking a plan sentence is cosmetic, dropping an answer is not, so the doubtful case now resolves towards shipping the turn. * studio: keep articles in repeat comparison and exclude missing-answer phrasing Articles are not filler: dropping them made "search for The Who" and "search for Who" compare equal, so a corrected target ended the nudge. _FINAL_ANSWER_SIGNAL matched "the answer is not in the provided context", which announces a missing answer, so the plan behind it shipped as the final response instead of being suppressed. Negated forms are now excluded. * [pre-commit.ci] auto fixes from pre-commit.com hooks for more information, see https://pre-commit.ci * studio: tighten the pivot and final-answer signals, drop filler-insensitive repeats The purpose clause in "call web_search to summarize the results" matched the final-answer signal, so the plan shipped instead of being suppressed; that alternative is gone. A pivot word now has to carry text of its own, since "I should call web_search, though." answers nothing. Repeat detection no longer ignores filler words. No word is reliably filler: dropping them to absorb rewording also absorbed the target ("OK Go" became "Go"). A missed repeat costs one nudge out of the cap; a false one strands the plan unexecuted. * studio: exempt offers of help, and add a measured accuracy floor Offering to help hands control back exactly like the existing "let me know" exemption. On a corpus of real model turns, "I'll do my best to help" and "allow me to assist" close a clarification request and never precede a tool call, but they were read as intent and re-prompted. "help you" keeps its plan reading when an action verb follows it. The new test scores the classifier against 300 turns captured from three local GGUF models, each one a finished answer: the turn called no tool, and three regenerations behind the production nudge produced no tool call either. Over those turns, wasted nudges go from 36 (12.0%) on main to 5 (1.7%), and retries whose text would be discarded from 60 (20.2%) to 1 (0.3%). Until now these patterns were tuned on hand-written example sentences, which cannot show how often the classifier is right on real output. * [pre-commit.ci] auto fixes from pre-commit.com hooks for more information, see https://pre-commit.ci --------- Co-authored-by: pre-commit-ci[bot] <66853113+pre-commit-ci[bot]@users.noreply.github.com> Co-authored-by: Daniel Han <danielhanchen@gmail.com> --- studio/backend/core/inference/llama_cpp.py | 94 +++- .../core/inference/safetensors_agentic.py | 5 + .../core/inference/tool_call_parser.py | 72 ++- .../backend/tests/data/plan_vs_answer.jsonl | 300 ++++++++++++ .../backend/tests/test_llama_cpp_tool_loop.py | 456 ++++++++++++++++++ .../tests/test_plan_classifier_accuracy.py | 96 ++++ .../tests/test_safetensors_tool_loop.py | 151 +++++- 7 files changed, 1149 insertions(+), 25 deletions(-) create mode 100644 studio/backend/tests/data/plan_vs_answer.jsonl create mode 100644 studio/backend/tests/test_plan_classifier_accuracy.py diff --git a/studio/backend/core/inference/llama_cpp.py b/studio/backend/core/inference/llama_cpp.py index dcfbfb3338..712caf43e5 100644 --- a/studio/backend/core/inference/llama_cpp.py +++ b/studio/backend/core/inference/llama_cpp.py @@ -95,6 +95,8 @@ from core.inference.tool_call_parser import ( MAX_ACT_REPROMPTS as _MAX_REPROMPTS, NUDGE_TOOL_CALLS_STATUS as _NUDGE_TOOL_CALLS_STATUS, REPROMPT_MAX_CHARS as _REPROMPT_MAX_CHARS, + is_reprompt_repeat as _is_reprompt_repeat, + is_reprompt_restatement as _is_reprompt_restatement, is_short_intent_without_action as _is_short_intent_without_action, reprompt_to_act_message as _reprompt_to_act_message, ) @@ -361,12 +363,32 @@ _DEFAULT_STREAM_STALL_TIMEOUT_S = 120.0 # 2 min # loop).
