After b464fdc3 (preserve .git on release switch), the hasGit-based
channel detection is unreliable — .git now exists for both release
and nightly installs, so page refresh always reset the channel.
- Add _resolveChannelFromSettings() with migration heuristic:
!hasGit → release (ZIP), detached HEAD → release (on tag),
on branch → nightly. Uses gitInfo.branch from check-updates.
- Persist resolved channel to settings.json on first load
(one-time migration) and on explicit switchChannel.
- Add update_channel validation (release|nightly) in backend
update_settings handler.
- Remove hasGit-based guessing from initialize(); defer to
checkForUpdates where full gitInfo is available.
- Channel resolution runs before checkForUpdates early-returns
to avoid null channelMode on reload-within-interval.
Tests: 361 passed.
Move reverse-migration logic from get_model_folder() (hot path, called on
every metadata/example-images request) to ExampleImagesMigration, where it
runs once at startup. On network storage this was causing 22-38s delays
per LoRA card click.
Additionally optimize prune_stale_example_images() to read the directory
listing once instead of per image entry (O(N*M) → O(M)). Also reorder
consolidation checks so regex filters run before filesystem stat calls.
Previously, switching to the release channel would delete .git/ and
fall back to a ZIP download. This broke update.bat, manual git
commands, and CM git-based update detection.
Now the release path uses git checkout <latest-tag> when .git exists,
and only falls back to ZIP when .git is absent (CM CNR installs).
.git is never deleted - the ZIP→nightly path remains a one-way
upgrade via _init_git_repo.
Also updates locale strings (en, zh-CN, zh-TW, ja) to remove the
now-inaccurate "remove the Git repository" wording.
switch_channel has three destructive code paths (git reset + clean,
git init + checkout --force, and rmtree + ZIP replace) that were
missing the _stage_preserved_items / _restore_preserved_items safety
net already applied to perform_update.
Wrap the channel-specific logic in a try/finally so preserved user
data (settings.json, civitai/, cache/, etc.) is physically moved
outside plugin_root before any git operation and always restored.
Move settings.json, civitai/, wildcards/, backups/, stats/, logs/,
cache/, and model_cache/ to a temp directory before git reset/clean
or ZIP replacement, then restore them in a try/finally block.
This prevents data loss on Windows where git clean -e exclusion
patterns can fail due to path-separator mismatches or where file
locks (open SQLite/log handles) cause the restore step to be skipped
on failure.
Also unifies three hardcoded skip lists (_clean_plugin_folder,
skip_items, skip_tracked) to derive from the single _PRESERVE_DIRS
constant, fixing drift where logs/ was missing from the ZIP path.
The compare API URL format compare/{local_hash}...main returns
status='ahead' when main is ahead of the local commit. The count is
in the ahead_by field, not behind_by. The old code only read behind_by
which is always 0 in this case, causing the UI to show 'Up to date'
when actually several commits behind.
Also handle status='diverged' (both sides have unique commits) by
reading ahead_by for the remote-ahead count.
Frontend adds a hash comparison fallback: if behind_by is 0 but local
and remote commit hashes differ, show 'Behind main' instead of the
incorrect 'Up to date'.
Tests: _AheadCompareDownloader and _DivergedCompareDownloader mocks
for the two status paths.
When downloading a diffusion model (UNet) from the checkpoints page, the
download modal's location step always showed checkpoint roots and paths.
Now the modal detects the file subtype and switches to unet_roots endpoint,
default_unet_root key, and 'unet' path template.
- Add POST /api/lm/switch-channel endpoint with git init / ZIP fallback
- Add _backup_git/_restore_git helpers with safe rollback
- Version-info endpoint now returns has_git flag for auto-detection
- Check-updates always returns releases (changelog) regardless of channel
- Nightly mode shows 'N commits behind main' with commit hash and date
- View on GitHub link points to /commits/main in nightly mode
- Channel toggle UI with pill-style buttons in update modal
- Confirmation dialog with Esc / backdrop-dismiss support
- Channel derived from has_git on every page load, no localStorage
- i18n: 11 new keys translated across 9 non-English locales
- CSS: unified card-style sections in _base.css
- Tests: 8 new tests covering switch-channel, nightly response, init_git_repo
Two bugs prevented type-signature-based fallback from working:
- metadata_hook.py used getattr(obj.__class__, 'RETURN_TYPES')
which fails when _async_map_node_over_list is called with
a class (not instance) — obj.__class__ is the metaclass
'type', which has no RETURN_TYPES. Fixed: getattr(obj, ...).
- metadata_registry.py used type(extractor) is GenericNodeExtractor
to dispatch return_types. NODE_EXTRACTORS stores class
references, not instances; type(Class) is always 'type',
never the class. Fixed: extractor is GenericNodeExtractor.
GenericNodeExtractor (previously a no-op) now inspects
RETURN_TYPES to detect MODEL loaders and CONDITIONING
encoders in nodes not registered in NODE_EXTRACTORS.
- Propagate return_types from the hook layer through the
registry to GenericNodeExtractor.extract() and update().
- MODEL detection: scan ckpt_name/unet_name/model_path/
model_name/gguf_name fields, validate by extension.
- CONDITIONING detection: scan text/clip_l/t5xxl/prompt
fields, store prompt text and conditioning tensor.
- _fill_missing_metadata also checks node_cache, so
GenericNodeExtractor-handled nodes survive cache.
Users can now right-click nodes and assign meta hints
(primary_model, primary_sampler, positive_prompt,
negative_prompt) to override the metadata processor's
heuristic inference.
- Store extra_data from the API request so workflow node
properties (including lm_marker_role) are accessible
during metadata processing.
- _get_user_marks scans extra_data.extra_pnginfo.workflow
for meta_* marks, falling back to prompt.original_prompt.
- extract_generation_params checks user marks before
heuristic inference for sampler, model, and prompts.
- Warn on duplicate marks or invalid marked nodes.
Drop the SequenceMatcher-based fuzzy_match fallback that froze the server
when FTS returned empty results. FTS now returns empty set for zero results
(no fallback), and when the index is not yet ready, search returns empty
rather than scanning all items in Python.
The previous tooltip was misleading: users thought workflow embedding was
automatic. New wording explains this opt-in flag stores the complete
workflow inside images, allowing one-click restoration via drag-and-drop.
PNG and WebP only.
Add two new optional parameters to the Save Image node:
- webp_method (INT, 0-6, default 6): Controls WebP compression level.
0=fastest/largest, 6=slowest/smallest. Previously hardcoded to 0.
- jpeg_subsampling (INT, 0-2, default 0): Controls JPEG chroma
subsampling. 0=4:4:4 (best quality), 1=4:2:2, 2=4:2:0.
Frontend JS extension hides/disables each parameter when the
selected file_format doesn't apply (e.g., webp_method is hidden
when saving as PNG or JPEG). 7 new tests cover parameter plumbing
and default consistency across INPUT_TYPES, save_images(), and
process_image().
hydrate_model_data replaces model_data with .metadata.json content which
may lack sha256 (corrupted file, concurrent write, etc.). Restore the
cached sha256 after hydration and persist the fix back to disk so
subsequent lookups don't hit the same error.
Also improve error log to include file_path for debugging.
- Replace plain-text Lora hashes with Hashes JSON dict matching A1111 convention
- Add Civitai resources JSON array with AIR URNs for direct model version linking
- Add Clip skip, Version: ComfyUI fields to generation params line
- Build AIR strings from local scanner cache (no API calls needed)
- Add complete sampler name mapping (CIVITAI_SAMPLER_MAP) and base model → AIR slug mapping (BASE_MODEL_AIR_SLUG) sourced from civitai ecosystem constants
- Remove lora text prepending from prompt line; LoRA info now in structured JSON sections
LM Studio and some other OpenAI-compatible servers reject
response_format=json_object but accept json_schema. Switch to the
equivalent json_schema format and add a fallback that retries
without response_format when the provider rejects the format type.
widget.value is a getter/setter that returns a new array on every read,
so handleStrengthDrag with updateWidget=false mutated a discarded copy.
Introduce __dragActive flag to suppress renderLoras in setValue during
drag, allowing mutations to persist through widget.value without
destroying the DOM. Use try-finally to guarantee flag cleanup.
The validation in getApiEndpoints threw for page types not in
MODEL_TYPES (e.g. 'recipes'), crashing the recipes page initialization
when FilterManager calls it via createBaseModelTags(). The throw was
synchronous and outside the fetch().catch() chain, causing an uncaught
promise rejection that aborted the entire app initialization.
getApiEndpoints is a URL builder -- validation belongs to callers that
need strict type checking (they already use isValidModelType()). For
non-model-type pages like recipes, the generated URLs are correct
(the backend does have /api/lm/recipes/* routes).
Fixes regression from f53f859a (feat(filter): add debounced tag search).
