Empty folders (tracked in the scan-recorded all_folders list, same source
the move/download destination picker uses) can now be surfaced in the
folder sidebar via a view-options toggle, dimmed when their subtree holds
no models. Folders can be created directly from the sidebar through a new
POST /api/lm/{prefix}/create-folder endpoint with library-root
containment checks; the scanner records the new directory incrementally
so the tree reflects it without a rescan.
The sidebar header moves its view toggles (tree/list, recursive, empty
folders) into a "..." menu to fit the new create-folder button.
A LoRA named `lora-sd1.5-backlight_slider_v10.safetensors` showed up in the
manager as `lora-sd1`, hid itself from searches for the rest of its name, and
collapsed into the same lora syntax tag as every sibling sharing the prefix.
The name was cut twice. `_process_model_file()` imports a third-party
`.civitai.info` sidecar by handing `from_civitai_info()` the local stem with
the extension already stripped, and the builder then stripped a second
"extension" from it -- `os.path.splitext` reads everything after the last dot
as one, so the version dot in `1.5` ended the name. The download path never
hit this because API filenames keep their extension and only need one strip.
Pass the real basename from the migration site, and make the builder strip
only a recognized model extension (`strip_model_extension`), so both input
shapes resolve to the same stem. The `model_name` fallback that reused the
same expression is fixed with it: on a sidecar without `model.name` the
display name was truncated too.
Libraries already corrupted do not heal on their own: the incremental Refresh
skips paths already in the cache (only a full rebuild reloads metadata) and
startup hydrates rows from SQLite as-is, so the wrong name survives restarts.
Reconcile now compares each cached row against the stem of its file path --
one string compare per file and no extra syscall, so a clean library pays
nothing -- and repairs mismatching rows through `load_metadata()` (which
normalizes the sidecar) and the existing in-place `_sync_cache_from_metadata_impl()`
path, which writes a targeted single-row SQL delta instead of a full save.
Repairs are one-shot, and a missing or corrupt sidecar keeps its row so a full
rebuild can recreate it without losing tags or civitai data.
Tests: the builder keeps dotted stems for all four model classes and still
strips real extensions; the migration writes the full local name to the
sidecar; and reconcile repairs memory, sidecar and SQLite row, runs exactly
once, and never reads metadata on a clean library.
A model file could only ever be linked to huggingface.co: `set_hf_url`
validated the URL with a huggingface-only regex, the agent fetched the card
from a hardcoded HF URL, and the readme processor built every relative image
path off `https://huggingface.co/{repo}/resolve/main`. ModelScope publishes the
same model-card convention (README.md + YAML frontmatter, often carrying
`base_model:` and `trigger_words:`) behind a public, key-less API, so the
enrichment pipeline could already serve it - it was the plumbing that was
HF-shaped, not the idea.
Make the external source a first-class, provider-driven concept:
- New `py/services/model_sources/` registry. A `ModelSource` owns URL
recognition (lenient for stored values, strict for user input), the
canonical page URL, model-card fetching, the asset base URL and the
capability flags. `HuggingFaceSource` is the previous logic relocated;
`ModelScopeSource` reads `/models/{o}/{n}/resolve/{master|main}/README.md`
and falls back to `/api/v1/models/{o}/{n}/repo`. `TensorArtSource` is
link-only on purpose: tensor.art answers plain HTTP clients with a
Cloudflare challenge and its internal API (ap-east-1.tensorart.cloud /
cn.tensorart.net) rejects every /v1/model/* route with "invalid
authorization header", so it declares supports_enrichment=False rather than
failing silently later.
- Metadata gains `source_platform` + `source_url`; `hf_url` stays as a
read/write alias, written only for Hugging Face, so existing sidecars,
cached rows and third-party consumers keep working. Normalisation runs at
the scanner, the persistent cache (both directions, plus two new columns
behind an ALTER migration) and the linking handler - which is what stops a
user who switches sources from leaving a stale `hf_url` on a ModelScope
model.
- The agent pipeline keys off the provider instead of `hf_url`: the fast-fail
gate now explains *why* a model is skipped (no source / unknown source /
source without a reachable card), the prompt context exposes
source_url/source_id/source_label/asset_base_url while still filling the
legacy hf_url/repo aliases, and the four README image extractors take a
base_url (defaulting to HF) so relative paths resolve against the right
site. Version grouping generalises to hf: / ms: / ta: keys.
- `POST /api/lm/set-hf-url` keeps its path and its legacy payload keys but
accepts `source_url`, validates against every provider and returns the
platform. `GET /api/lm/model-sources` lets the UI render the supported-site
list from the server.
- Frontend: a `modelSourceHelpers` mirror of the registry drives the link
dialog, the card/modal globe (branded "View on ModelScope/TensorArt"), the
version-group key and the enrichment gate; the versions tab no longer sends
ms:/ta: keys to the CivitAI API.
TensorArt stays in the list because provenance is worth keeping even when the
card is unreadable - the dialog says so plainly ("Sites that don't expose one
(currently TensorArt) can only be linked") and the context menu disables
enrichment with a matching tooltip, instead of the user getting
"Unsupported URL".
Verified against the real ModelScope API: jj3550945163/Krea-2-LORA returns a
1882-byte card whose frontmatter carries base_model/tags/trigger_words, and
relative images resolve to .../resolve/master/....
Tests: backend 2815 passed; frontend 1130 JS + 91 Vue passed; pytest
tests/i18n and a Jinja compile pass over templates/. The nine locales carry
[TODO: Translate] for the new strings, completed in the next commit.
Other Models management is now opt-in: enable_other_models (default false)
plus the enabled_other_sub_types allow-list replace the unreleased additive
enabled_other_folders key.
- config._get_enabled_other_folder_keys() is the single scan gate; a new
refresh_other_roots() rebuilds roots and preview roots on toggle.
- ModelScanner gains a _should_keep_cached_entry() hydration hook and
on_library_changed(reconcile=...) so switching a sub_type off drops its
entries (and hash/autov3 rows) at load time and switching it on rescans.
- OtherScanner filters location-derived entries accordingly.
- Other routes reject every other type while off (or a disabled sub_type) and
expose an "other_disabled" page flag; download routing returns a disabled
marker instead of guessing; the download manager refuses other-type
downloads and default-path routing for switched-off sub_types.
- Doctor / init-status / refresh-all skip the other scanner while off; the
scanner stays registered so staged pending-deletes still merge.
- Tests updated with explicit opt-in fixtures plus new gating coverage.
The include_empty folder tree (download/move modals) walked every model
root synchronously on the event loop via get_all_folders(). On network
(NAS) roots this froze the whole server for the duration of the walk —
blocking WebSocket progress, aria2 RPC and the download queue — and the
5s TTL re-triggered the walk on nearly every modal interaction.
The scanners already visit every directory during cache scans, so record
the full directory list (including empty folders) there instead:
- _gather_model_data/_reconcile_cache collect directories during the
existing walks; reconcile refreshes and persists the list even when no
model files changed.
- ModelCache gains an all_folders field (None = never recorded).
- PersistentModelCache stores the list in a new folders table, with a
cache_meta flag distinguishing 'recorded empty' from legacy snapshots.
- get_all_folders() is now a pure in-memory read. A legacy snapshot
triggers a one-shot backfill walk in a worker thread (never on the
event loop) that records and persists the list.
- Moves add the destination folder (and parents) incrementally instead
of invalidating a TTL cache.
A no-change Refresh still computed os.path.realpath for every model file
in the library and for every cached entry. Both values are only ever
consulted when a discovered file is missing from the cache, so on a
50k-file library they cost ~1.3s and ~0.6s while being used zero times.
- Compute the per-file realpath only after the exact cache match fails
- Build the physical-path alias map lazily on the first miss; the
cross-run alias guard (overlapping roots / symlink layout changes)
still keeps the cached entry instead of a delete + re-add, which would
re-read metadata and re-hash the whole library
- Snapshot get_model_roots() once for the new-file pass instead of
re-reading it for every added file
- Run the duplicate-path integrity pass only when the snapshot already
contained duplicates or files were appended; a clean, unchanged cache
has nothing to clean. Duplicates can only be introduced by external
code rewriting raw_data or by this pass's own appends.
Zero-change reconcile drops from ~1400ms to ~120ms on 50k files, and an
alias flip still re-processes 0 files (#1108 investigation).
Moving a checkpoint into a unet root (or vice versa) moved the file and
updated the in-memory cache, but three stale spots survived until a
manual cache rebuild:
- The moved .metadata.json kept the old sub_type, and the opportunistic
sync_cache_from_metadata path (fired by get_model_metadata and example
image metadata updates) trusted it, reverting the cache entry and the
SQLite snapshot to the pre-move sub_type. Loader nodes filter strictly
on sub_type, so the model stayed listed under the old type.
- The manager page discarded the move response's cache_entry, so the
card badge (CKPT/DM) and context menu label kept showing the old type.
Fixes:
- move_model now re-resolves sub_type from the target location (new
resolve_sub_type_for_path hook) and persists it into the moved
.metadata.json.
- _sync_cache_from_metadata_impl runs desired entries through
adjust_cached_entry so location-derived fields cannot be re-poisoned
by stale metadata snapshots.
- MoveManager carries cache_entry.sub_type into the in-place card
update so badge and context menu reflect the new type immediately.
Broadcast typed scan_progress messages over /ws/fetch-progress from the
manual refresh/rebuild paths of ModelScanner and RecipeScanner, and
render percent, processed/total, current file name and an EMA-smoothed
ETA in the loading overlay. Hardcoded refresh strings move to i18n
(common.scanProgress); WS connection failure falls back to the previous
static loading behavior.
Bulk delete merged staged batches by physically moving each loser's
files into the winner's batch dir with os.rename. Cross-volume bulks
(winner and loser on different filesystems) always hit EXDEV, forcing a
rollback and degrading to the batch_ids array with per-batch undo.
Merge is now manifest-only: loser entries are appended to the winner's
manifest with their staged paths unchanged, so staged files keep living
in each model's own .lm-pending-delete/<batch_id> dir (no data IO, no
EXDEV). Loser dirs are recorded in the winner manifest's merged_sources
and each loser manifest is stamped merged_into so its own purge timer, a
post-restart sweep or a direct undo call no-op. A cross-volume bulk is
one undoable batch again, and undo/purge clean up the loser dirs once
the merged batch settles.
Consolidate the duplicate name-matching logic into ModelScanner:
find_matching_models is now the single core, using each scanner's own
file_extensions for suffix stripping. get_model_info_by_name gains
require_unique/base_model kwargs while legacy route behavior is kept
byte-identical. reconnect_lora passes the recipe base model as a guard
and distinguishes ambiguous, base-model-mismatched, and missing LoRAs
in its error messages.
- Three-state autov3 field (not-checked / checked-unavailable / 12-hex value)
in .metadata.json sidecars, in-memory ModelHashIndex, and SQLite
(models.autov3 column + autov3_index table) with column-presence migration
- Background self-terminating backfill for legacy rows: per-model-type
concurrency guard, executor-offloaded I/O, Civitai-first resolution
(SHA256-matched version file) falling back to the embedded safetensors
header hash
- Civitai-first propagation on metadata refresh, scan, and download paths;
reject the empty-string SHA256 placeholder and strip OneTrainer 0x prefix
- List API hash filters and hash index lookups accept 12-char AutoV3
- Cap safetensors header reads at 64 MiB to prevent crafted-file allocation
- Prevent stale AutoV3 mappings on file replacement while preserving them on
same-file re-registration (lazy-hash completion)
- Add PersistentModelCache.update_single_model() for lightweight targeted
SQL update (single row + incremental tag/hash deltas, no full table scan)
- Add ModelScanner.sync_cache_from_metadata() with compare-first logic:
skips entirely when cache is already in sync; when stale, updates the
entry in-place (O(1) instead of O(n) remove+append), incrementally
adjusts tag counts/hash index/version index, and resorts only when
sort-relevant fields changed
- Wire sync_cache_from_metadata() into BaseModelService.get_model_metadata()
via fire-and-forget asyncio.create_task — disk I/O is already paid for
- Include identity re-validation guard against concurrent cache replacement
- Add 16 tests covering _cache_entries_differ, sync_cache_from_metadata
(no-change, in-place, fallback, conditional resort), and
update_single_model (insert, tag delta, hash delta)
Add a pure frontend node that shows filename and editable notes for
a selected LoRA. Connect any output from a LoRA Loader/Stacker/Randomizer/
WanVideoSelect to the lora_source input — selecting a LoRA in the source
widget updates the info display automatically.
- Python node (LoraInfoLM): display-only, no workflow execution
- Vue widget: filename label, auto-sizing notes textarea, save button
with ComfyUI toast feedback on save
- Frontend extension: wire-based selection propagation with stale-response
race guard; clears display on wire disconnect
- Backend: get-notes endpoint now returns file_path alongside notes;
matching supports full-path lora syntax; fix NoneType crash in
trigger words endpoint; document cache file_name invariant
- Wired into all four lora widget nodes (Loader, Stacker, Randomizer,
WanVideoSelect)
Cache corruption (NULL model_name/file_name from legacy DB rows or partial
writes) caused format_response to raise KeyError/AttributeError, failing the
entire /loras/list request and showing no models in the UI.
Fix across three layers:
- format_response (lora/checkpoint/embedding): replace direct dict[] access
with .get() fallbacks; return None for entries missing file_path
- handlers: filter None entries from list/excluded/fetch/duplicate/conflict
endpoints instead of letting them crash or appear as null in responses
- model_scanner: always use validate_batch repaired copies (previously
discarded when no invalid entries, leaving None values in raw_data)
- persistent_model_cache: add or-empty-string guards on read and write for
nullable TEXT columns (model_name, file_name, folder, base_model, etc.)
Autocomplete, copy/send-to-workflow, and recipe syntax now emit
<lora:folder/name:strength> instead of <lora:name:strength>, using
relative paths to disambiguate identically-named loras in different
subfolders without requiring file renames.
Backend: 3-tier hybrid resolution (path → bare → basename fallback)
across get_lora_info, get_lora_info_absolute, get_model_preview_url,
get_model_civitai_url, get_model_info_by_name, get_lora_metadata_by_filename,
and get_hash_by_filename. Also fix get_random_loras and get_cycler_list
to return path-prefixed names for randomizer/cycler consistency.
Frontend: autocomplete, copyLoraSyntax, handleSendToWorkflow emit
folder-prefixed syntax. extract_lora_name preserves relative paths.
Saved image metadata (<lora:...> in EXIF) intentionally keeps basename-only
for compatibility with A1111/Forge ecosystem.
Duplicate filename detection is only relevant for LoRAs, which use
basename-only syntax (<lora:name:strength>). Checkpoints and diffusion
models reference files via relative paths with extensions, so filename
conflicts there are false positives — there is no resolution ambiguity.
Both _log_duplicate_filename_summary() and DoctorHandler's
_check_filename_conflicts() now skip scanners with model_type != 'lora'.
Detects when multiple model files share the same basename (causing
ambiguity in LoRA resolution), logs warnings during scanning, and
provides a "Resolve Conflicts" button in the Doctor panel. Resolution
renames duplicates with hash-prefixed unique filenames, migrates all
sidecar and preview files, and updates the cache and frontend scroller
in-place so the model modal immediately reflects the new filename.

- UI: Implement virtual scrolling in TagsModal for performance
- Initial display 200 tags, load more on scroll
- Show all results when searching
- Remove lora_pool_tags_limit setting to simplify UX

- Revise technical documentation to mark Phase 5 as completed and remove outdated TODO items
All cleanup tasks for the model type refactoring are now complete, ensuring consistent use of `sub_type` across the codebase.
This commit resolves the semantic confusion around the model_type field by
clearly distinguishing between:
- scanner_type: architecture-level (lora/checkpoint/embedding)
- sub_type: business-level subtype (lora/locon/dora/checkpoint/diffusion_model/embedding)
Backend Changes:
- Rename model_type to sub_type in CheckpointMetadata and EmbeddingMetadata
- Add resolve_sub_type() and normalize_sub_type() in model_query.py
- Update checkpoint_scanner to use _resolve_sub_type()
- Update service format_response to include both sub_type and model_type
- Add VALID_*_SUB_TYPES constants with backward compatible aliases
Frontend Changes:
- Add MODEL_SUBTYPE_DISPLAY_NAMES constants
- Keep MODEL_TYPE_DISPLAY_NAMES as backward compatible alias
Testing:
- Add 43 new tests covering sub_type resolution and API response
Documentation:
- Add refactoring todo document to docs/technical/
BREAKING CHANGE: None - full backward compatibility maintained
- Return cache entry data from model move operations for immediate UI updates
- Add recalculate_type parameter to update_single_model_cache for proper type adjustment
- Propagate cache entry through API layer to frontend MoveManager
- Enable virtual scroller to update moved items with new cache data

- Extract file extension from model filename to handle different file types
- Update model scanner to pass file extension when deleting models
- Add test case for GGUF file deletion to ensure proper cleanup
- Maintain backward compatibility with existing safetensors models
This change allows the model lifecycle service to properly delete GGUF model files along with their associated metadata and preview files, expanding support beyond just safetensors format.
