The custom-root sd.cpp removal requires the .unsloth-studio-owned marker (written by
install_sd_cpp_prebuilt) before deleting, so a user's own stable-diffusion.cpp checkout
beside a custom root is kept. The default-mode removal of ~/.unsloth/stable-diffusion.cpp
was unconditional, so a user who keeps their own checkout at that path (or points
UNSLOTH_SD_CPP_PATH there), or a pre-marker Studio build, would have it deleted on
uninstall. Guard the default-mode removal on the same owner marker in both uninstall.sh
and uninstall.ps1. Extends the sd.cpp uninstall shell test with owned (removed) and
unowned (kept) default-mode cases.
- _local_model_task now tags a local diffusers pipeline that resolves to a video
family (LTX / Wan / Hunyuan) as text-to-video, mirroring the cached-repo
_cached_repo_task, so supported local video pipelines surface in the Video
On-Device picker instead of being routed to the Images picker where the image
loader rejects them. Gated on _local_is_diffusers so only a real loadable
pipeline dir reaches the video check.
- Video validate_load_request now rejects a local pipeline pick whose directory has
no model_index.json before the GPU handoff, mirroring the image loader, so a bad
local pipeline can no longer evict the resident model and only then fail deep in
from_pretrained.
- The custom/env-mode uninstall now removes a sibling stable-diffusion.cpp only when
it carries the Studio owner marker. install_sd_cpp_prebuilt writes the canonical
.unsloth-studio-owned marker on install; uninstall.sh and uninstall.ps1 keep any
unowned checkout (a user's own git clone of stable-diffusion.cpp beside a custom
Studio root is no longer deleted). A pre-marker Studio build is left behind rather
than a user file removed.
Adds regression tests: local video pipeline tagged text-to-video (and a video-named
non-pipeline dir stays untagged so it can never trigger a doomed pipeline load), the
video local-pipeline preflight rejection, the install ownership marker, and the
uninstall keeping an unowned sibling while removing an owned one.
- Diffusion dataset upload now streams each file into a sibling temp file and
atomically os.replace()s it into place only after the whole file is written and
within the size cap. A mid-batch 413 (or any abort) removes the temp, never an
example already stored under the same name, so re-uploading a too-large batch can
no longer truncate or delete a previously uploaded image.
- _diffusion_dataset_summary counts an image as captioned only when it resolves to a
non-empty caption via the same sidecar-over-metadata precedence the trainer uses. An
empty (tombstone) sidecar shadows a metadata row and makes the trainer skip the
image, so counting it over-reported caption_count and mislabeled an effectively
uncaptioned dataset as captioned.
- uninstall.sh/.ps1 now remove a custom/env-mode Studio's native diffusion build that
installs beside the root as a stable-diffusion.cpp sibling (find_sd_cpp_binary
resolves it from the Studio home's parent), guarded by the same unsafe-path check,
and stop processes locking the default-mode stable-diffusion.cpp before removing it.
Adds regression tests for the upload data-loss and caption-count paths and a hermetic
shell test for the custom-root stable-diffusion.cpp removal.
