* Studio: fix 4 failing studio_unit_tests on main
Three of the failing tests had drifted from production:
1. test_health_response_reports_desktop_capability_fields stubbed
`routes` with a SimpleNamespace that omitted `inference_studio_router`,
so importing studio.backend.main raised ImportError. Add the missing
router stub.
2. test_local_recipe_token_preserves_desktop_marker and
test_local_recipe_token_keeps_web_marker_absent decoded the local
provider's api_key as a JWT, but _inject_local_providers now mints
a unified sk-unsloth-* internal API key (not a forwarded JWT), so
jwt.decode raised "Not enough segments". Renamed and rewrote both
tests to validate the API-key contract: starts with
storage.API_KEY_PREFIX and authenticates via get_current_subject as
the real admin user. The web vs desktop distinction is irrelevant
at this layer because the unified API-key path does not carry
session flags.
The fourth failure was a real production bug:
3. test_github_validate_skips_live_access_with_honest_note expected
github-seed validation to return valid=True per
_GITHUB_VALIDATE_NOTE ("GitHub access and rate limits are checked
when the run starts"). The validate route called
build_config_builder which lazy-imports the optional data_designer
module; when it is missing, the bare except blocked the recipe.
Catch ImportError specifically and treat it as a deferred check,
matching the documented intent.
Verified all 4 tests pass and the rest of studio/backend/tests still
pass (608 total, with the only remaining failures being environment
specific: 4 GPU-aware tests on a no-GPU host and 1 Anthropic-API
smoke test, both unrelated).
* Studio: fix 3 test_gpu_selection route tests after load_model signature change
`routes/inference.load_model` gained a `fastapi_request: Request`
positional argument (used to read `app.state.llama_parallel_slots`
inside the GGUF path), but the three TestRouteErrors cases that
exercise the early validation path were not updated and failed with
`TypeError: load_model() missing 1 required positional argument:
'fastapi_request'`.
Pass a SimpleNamespace mock that satisfies the attribute path the
production code reads. The validation under test fires before the
mock is consumed, but supplying the realistic shape protects against
regressions if the validation order changes.
Affected tests:
- test_inference_route_rejects_gpu_ids_for_gguf
- test_inference_route_returns_400_for_invalid_gpu_ids
- test_inference_route_returns_400_for_uuid_parent_visibility_gpu_ids
* Studio: address review feedback on validate.py ImportError handling
Two reviewers flagged the ImportError bypass added in b0d33cf:
- chatgpt-codex-connector[bot]: catching bare ImportError marks recipes
as valid even when build_config_builder fails for unrelated import
problems (broken internal imports, missing transitive deps after a
version bump), hiding real regressions until run start.
- gemini-code-assist[bot]: silent pass discourages troubleshooting;
the deferred-validation case should be logged at debug level.
Tighten the bypass to ModuleNotFoundError where the missing module name
starts with "data_designer". Other ImportErrors propagate to the outer
handler and surface as validation failures, restoring the visibility
the reviewers asked for. Add a debug-level log entry that names the
missing module so operators can trace why validation deferred.
* add unsloth studio desktop app
* Fix review findings
- studio/src-tauri/tauri.conf.json: retarget updater to staging repo
(danielhanchen/unsloth-staging-2); switch to unslothai/unsloth on upstream merge.
- studio/src-tauri/linux/postremove.sh: drop the interactive read loop and the
/home/* iteration. Package maintainer scripts must stay non-interactive and
must not touch other users' data.
- studio/frontend/src/app/auth-guards.ts: honor tauriAutoAuth() boolean. Failed
auto-auth now redirects to /login; requireGuest/requirePasswordChangeFlow
only redirect to /chat when auth succeeds. The new early-return on failed
auth is intentional so the login / change-password flows remain reachable
when desktop auth is not yet established.
- studio/frontend/src/config/env.ts: keep fetched=false on health failure so
later calls retry instead of caching the client-side platform guess.
- studio/src-tauri/src/install.rs: pick the available system package manager
(apt-get, dnf, zypper, pacman); AppImage bundles run on non-Debian distros.
- studio/frontend/src/lib/open-link.ts + markdown-text/sources callers: return
boolean from openLink so callers only preventDefault on handled URLs; relative
hrefs now navigate natively.
- studio/frontend/src/features/settings/tabs/about-tab.tsx: fetch(apiUrl(...))
so the version request targets the backend port in desktop mode. The bare
/api/health predates the Tauri webview (blame: the earlier onboarding commit,
which ran with same-origin frontend/backend); in desktop mode the webview
origin is tauri://localhost so the bare path fails.
- install.ps1: gate the install_python_stack.py hotfix on a sentinel comment
instead of a content regex; append the sentinel after applying so reruns
are unambiguous.
- unsloth_cli/commands/studio.py _write_auth_secret: use the atomic mkstemp +
os.replace path on Windows too; chmod calls are wrapped in try/except OSError.
- studio/src-tauri/src/preflight.rs probe_existing_backends: fan out the health
probes concurrently; desktop-auth status still runs sequentially per candidate.
reqwest::Client is internally Arc-wrapped so the in-loop .clone() is a
refcount bump, not a deep clone; annotated inline.
- studio/src-tauri/src/preflight.rs run_cli_probe: wait() after kill() to reap
the child, matching probe_cli_capability.
- studio/src-tauri/src/process.rs + main.rs: add stop_backend_detached and use
it from the tray quit handler so the 5s graceful-wait does not block the
Tauri main loop. RunEvent::Exit keeps the synchronous safety-net call.
- studio/backend/main.py: drop the permissive localhost CORS regex in
api-only mode; the explicit allow_origins list is sufficient.
- .github/workflows/release-desktop.yml: drop max-parallel: 1 so platform
builds run in parallel, and lift releaseBody to an env var so the three
tauri-action invocations share one source of truth.
* Fix review findings (loop 2)
- studio/backend/auth/storage.py update_password: clear_desktop_secret()
alongside clear_bootstrap_password() so rotating the admin password
also revokes any previously provisioned .desktop_secret. Without this,
an old local desktop credential keeps minting fresh admin tokens via
/api/auth/desktop-login after a password rotation.
- studio/src-tauri/src/desktop_auth.rs provision_desktop_auth: wrap
cmd.output().await in tokio::time::timeout(30s). DESKTOP_AUTH_LOCK is
held across the whole desktop_auth flow, and previously a hanging
`unsloth studio provision-desktop-auth` subprocess would pin the lock
indefinitely and freeze every subsequent desktop_auth call.
* Add review tests
* Consolidate review tests
Merge review-added tests into the existing studio/backend/tests/test_desktop_auth.py
(the PR's authoritative desktop-auth test file). Drops three scaffolding files under
tests/python/ in favor of five focused tests next to the tests they extend:
- test_update_password_clears_desktop_secret (runtime)
- test_update_password_on_unknown_user_leaves_desktop_secret_intact (runtime)
- test_cli_provisioning_delegates_to_storage_create_desktop_secret (source-level)
- test_cli_connect_auth_db_reads_storage_db_path (source-level)
- test_desktop_auth_provision_has_bounded_timeout (Rust source-level)
* Revert auth-guards.ts Tauri branches to unconditional form
The review loop on PR 5144 introduced a regression: the isTauri branch of
requireAuth redirected to /login when tauriAutoAuth() returned false, and
requireGuest / requirePasswordChangeFlow silently fell through on the same
condition. The Tauri desktop app authenticates via a local auto-generated
secret; it must never surface /login or /change-password to the user. A
failed auto-auth should let the startup layer retry, not expose a password
form.
Restore the three Tauri branches to the author's original unconditional
form (requireAuth: return; requireGuest / requirePasswordChangeFlow: throw
redirect({to: '/chat'})). Keep the rest of the review fixes -- the
apiUrl() fetch wrapping, authRedirect helper, and fetchAuthStatus refactor
are all legitimate improvements and are preserved.
* Revert release-desktop.yml to author's version
The review loop's workflow-file tweaks (drop max-parallel: 1, lift releaseBody
to an env var) are cosmetic. OAuth tokens cannot push workflow-file changes,
and fine-grained PATs cannot honor maintainerCanModify on a third-party fork.
Reverting the workflow file to wasimysaid's version lets the push go through
without needing a classic PAT with both repo and workflow scopes.
