- Around line 365-367: Remove the `PreviewImage().save_images` call and
`ui["background_images"]` assignment in the bounding-box output path; the
registered widget uses the connected input node’s image URL and does not consume
this field.

Commit at the top of each entry instead, so the hash runs with no transaction open. * Seed settled watch-list entries through insert_asset_specs tick_watch_list seeded each settled file through seed_asset_specs in the caller's session, where the enrich phase still held drain_pending's writes open, and each seed ran in a deferred savepoint that reads before it writes. Collect the settled specs and hand them to insert_asset_specs, which stats and hashes before opening one write session. The seeder commits the pending verifications before ticking, so no transaction is open while the watch list stats or waits for the write lock. * Read upload metadata before the claim transaction _create_upload_record read the file for system metadata after the content claim had opened a write transaction. Callers now extract the metadata before opening their session (or, when reusing content, before claiming it) and pass it in. The claim's own stat re-check stays inside the transaction: that is what makes the claim sound. * Keep the upgrade error when restoring the backup also fails If restoring the pre-upgrade backup raised, that exception replaced the upgrade's, and the backup's location was never logged. Log the upgrade error first, log where the pre-upgrade copy is kept if the restore or its cleanup fails, and re-raise the upgrade error either way. * Note the drains' session requirement and word the restore log for either failure The drains' per-entry commit only leaves no transaction open on a create_session() session. The restore log now covers a failed backup removal as well as a failed restore. The watch-list admission test patches insert_asset_specs, the seam tick_watch_list now calls. * Log the real error when a seed spec cannot be read observe_asset_specs treated every OSError as a vanished file, so a permission error or an I/O error on a file that still exists was reported only as "Skipping vanished asset during scan". A missing file is still handled as before; any other OSError is now also logged through _log_scan_error before the spec is skipped. The vanished-path test's fake now raises FileNotFoundError, the error a vanished file produces. * Report an unreadable seed spec once, without also calling it vanished * Skip a pending verification whose row changed while it was hashed Committing per entry means no lock is held while the file is hashed, so another writer can retire or replace the row in that time. The drain would then store a hash on a missing row, or split it and attach a record to the other writer's row. Re-read the row after hashing and skip it unless it is still live with the hash, size and mtime it was loaded with, as apply_reference_observations does. * Remove the stored upload file in the reupload claim test The test cleaned up its temp files but left the first upload's stored file in the output directory. * feat: ming-image support (Comfy-Org#16482) * Fix saving/loading ming image model breaking detection.

Only the attempt is capped at once per pass. * test(api): derive the expected assets flag from the manager under test The assertion asked for the flag with no argument, so it read the parameter default rather than anything the manager reported - in a test whose subject is the two agreeing. Passing the manager's own state keeps it honest if the setup ever yields an enabled manager. * test(assets): let a broken prompt worker import fail instead of skipping The fixture wrapped importlib.import_module in a bare except that called pytest.skip, so a circular import, a missing dependency or a syntax error in app/prompt_worker.py would retire all four resume-contract tests while CI stayed green. The whole premise of extracting the module is that main.py can import it, so an import failure has to be a collection error. The CPU guard is genuinely load-bearing — comfy.model_management selects its device at import time and a CUDA build with no driver raises there — so it is kept, but as a precondition rather than an exception handler, matching the args.cpu-before-import convention already used by the comfy_test and comfy_api_nodes_test modules. Nothing is caught now. * docs(assets): name the unattempted rows instead of the ones behind the cursor The cursor moves forward through ascending ids, so 'the rows behind it' reads as the rows already passed - the opposite of what is selected again. * fix(assets): only absorb duplicate-path races when seeding scanned assets * fix(db): copy the legacy database inside the process lock * fix(assets): drop watch-list entries on stat errors instead of aborting the scan * fix(assets): clean up temp uploads on validation failures Multipart parsing writes the uploaded bytes to a temporary file before it validates the remaining form fields, so a request rejected after its file part had already been read left the temp file and its uuid directory on disk. Routing those removals through delete_temp_file_if_exists also changes the success path. The previous helper returned early when the temp file was already gone, so it never reached the parent rmdir; the shared helper attempts the rmdir unconditionally. Moving the upload to its destination leaves the temp path absent, so a successful upload now also discards its empty uuid directory, closing a pre-existing leak. * fix(assets): keep updated_at stable on no-op renames * docs(assets): make module docstrings and the rebuild warning truthful * fix(assets): correct event-log status snapshots and failure telemetry * test(assets): make the keyset tie-breaker and temp-exclusion tests falsifiable * chore: comment cleanup Comment-Gate: 3 quarantined * fix(assets): keep unreadable filesystem metadata from failing a whole scan batch * fix(assets): remove temporary uploads on non-UploadError failures * fix(assets): preserve successful specs when a scan batch fault propagates * test(db): drop the inert legacy-copy patch from the path preparation tests prepare_file_db_path no longer copies the legacy database - that moved inside the process lock in _init_file_db - so patching copy_legacy_default_db here did nothing. Leaving it implied a side effect the function does not have, and would have masked one if it were reintroduced. * fix(assets): report specs committed before a batch fault and preserve the fault itself * fix(assets): distinguish partial batch insert failures * refactor(assets): collapse the duplicated batch fault deferral into seed_asset_specs * fix(assets): reject duplicate file parts instead of stranding the first upload * refactor(assets): reap empty upload directories without importing the API layer * fix(assets): emit the invalid-mtime event once per scan Every other per-file emit on this scan path is gated -- mark_emitted( "stat_failed:enrich"), "hash_discarded_modified", "hash_failed", "enrich_failed" -- but scanner.invalid_mtime fired per file, so a restored archive or a FAT volume of pre-epoch mtimes put one structured event per file into the stream the closed vocabulary exists to keep parseable. Counted and emitted once, carrying the count. seed_asset_specs receives no _ScanProgress object and neither does insert_asset_specs above it, so routing this through mark_emitted would mean changing both signatures plus the seeder call site; the count form needs neither and the event is now strictly more informative than N identical fieldless lines. The per-file logging.warning is unchanged, and the emit stays inside seed_asset_specs so the static call-site manifest still matches. test_seed_skips_negative_fresh_mtime_with_warning_and_telemetry now pins the full list of invalid_mtime lines to exactly ["... count=1"] instead of asserting one such line exists -- a strictly stronger assertion, and the only change the new field required. * fix(assets): keep spec construction failures from wedging the watch list get_name_and_tags_from_asset_path raises ValueError by contract when a path stops resolving to a configured root, and it sat outside the guard, as did compute_loader_path and mimetypes.guess_type. An escape skipped the _WATCH_LIST[:] = remaining write at the end, so drained entries stayed on the list and were re-attempted every tick while entries past the fault never reached the increment _WATCH_SCAN_RETRIES needs to retire them. The list wedged permanently. Spec construction is now inside a guard that drops just the offending entry, and the list write moved into a finally so no future escape can skip it. The loop walks an iterator rather than the list, so the finally can put back the entries it never reached instead of discarding them. New event name rather than reusing one: scanner.watch_seed_failed is emitted only when seed_asset_specs returns an error, and widening it to also mean "never got as far as seeding" would make it lie -- a consumer treating it as a database-health signal would get false positives from what is really a path layout problem. scanner.watch_spec_failed is registered in ALLOWED_EVENTS and in the static call-site manifest. * refactor(assets): export the live-path conflict check as public API scanner.py reached past the package's own re-export surface to import _is_live_path_conflict directly out of records.py. The underscore said module-private while the import said otherwise, and records.py deliberately publishes its public names through app.assets.database.queries -- which the same import block three lines above was already using. The use is correct and unchanged; only the name and the route change. Renamed to is_live_path_conflict, listed in the package __init__ import and __all__ alongside its siblings, and scanner.py now takes it from the package like everything else it imports from there. * docs(db): restore the rationale for locking before migration Commit 1dbcdcd and the comment-cleanup pass 8205022 reduced this to "All database reads and writes, including the legacy import, run under the lock", dropping the part that did the work: upstream master locks after migrating and justifies it with "Alembic uses its own connection, so we must wait until it's done before locking -- otherwise our own lock blocks the migration". That is false, the lock is on a separate <db>.lock file, and the surviving sentence said nothing to stop a contributor "fixing" the ordering back. Restored and adapted rather than pasted: the legacy copy and the db_exists probe now happen inside the lock, which the original text predates, so both are named in the list of things the ordering makes mutually exclusive. * fix(assets): stop a scan on memory exhaustion instead of deferring it MemoryError is an Exception, so the per-spec and per-batch handlers stored it alongside ordinary faults and carried on - allocating for every remaining spec and then every remaining batch while the process was already out of memory. Both handlers now let it through, and the scan records a failure and stops. * docs(assets): document the prune failure response and its None result The route gained a 500 PRUNE_FAILED branch and the seeder method gained a None return, both so a prune that did not run cannot be reported as a clean one. Neither contract was written down. * test(assets): assert the surviving spec count after a propagated fault * docs(db): shorten the lock-ordering comment while keeping its rationale * docs(tests): drop the cross-module justification from the import-order comment * test(assets): restore the cpu flag after the guarded prompt worker import * test(assets): restore the cpu flag even when the prompt worker import fails * fix(assets): drop asset_meta in a new migration instead of editing 0007 0007 shipped in v0.36.0, v0.37.0 and v0.37.1, so editing it would leave two installs at that revision with different schemas depending on when they upgraded. Restore 0007 to its released form and drop the unused asset_meta table in 0008 instead. Nothing reads or writes asset_meta; asset metadata lives in the JSON columns on assets. 0008 downgrades by recreating the table and its four indexes exactly as 0007 creates them. * refactor(assets): keep prompt_worker in main.py Custom nodes may reference main.prompt_worker, and tests can already import main (test_db_init_locking does), so the function stays where it was. Its body keeps the resume-on-failure handling and the pause flag that persists across loop iterations; the tests now call main.prompt_worker. * fix(assets): report the selected manager through the existing feature flags * fix(assets): record a failed prune in the scan status A failed prune left the scan's error list empty, so the run looked clean. Record it instead and let discovery continue as before. * test(assets): test the feature flag API directly instead of copying the startup write Both parity tests wrote SERVER_FEATURE_FLAGS["assets"] themselves, so they passed whatever startup did. Pin the one real claim - a no-argument get_server_features() reports the flag - in the feature flags tests, and drop the disabled case, which default_asset_manager already covers. * Bring Comfy-Org#16486's watch-list batching and seed logging into this branch The merge before this commit is `git merge -X ours origin/master`: in conflicting hunks it keeps this branch's side. This commit ports what Comfy-Org#16486 changed in those hunks. - tick_watch_list takes no session. It collects settled entries and seeds them in one batch through insert_asset_specs, keeping this branch's per-entry stat and spec handling and the finally that always rewrites the watch list. A failed seed is reported once per batch, since the batch only returns its first error. - seed_asset_specs no longer warns again for a skipped spec; observe_asset_specs already logged why. - Tests call tick_watch_list() without a session, bind the write session where they seed for real, and fake insert_asset_specs with its (created, error) return. The mid-drain fault now comes from stat, because seeding runs after the loop. * Note where the assets core flag is set and why prompt_worker catches BaseException --------- Co-authored-by: guill <jacob.e.segal@gmail.com> * Add missing RDNA2 arches to list. (Comfy-Org#16537) * feat(npu): support async weight offload streams (Comfy-Org#16057) Add device-aware torch-npu stream creation, current-stream lookup, and synchronization so the existing async offload path can run on Ascend NPU devices. Keep the feature opt-in and cover stream rotation and disabled behavior in the unit-test suite. * Small fix: skip unnecessary work. (Comfy-Org#16540) * Fix Qwen VL image preprocessing crash on 4-channel (RGBA) input (Comfy-Org#16548) process_qwen2vl_images() computed the patch grid from height/width only but flatten_patches kept every input channel, so a 4-channel image (e.g. Qwen-Image-2.1's RGBA VAEDecode output fed back as a reference image) inflated the patch count by channels/3 and crashed with a shape mismatch against the position embeddings. Drop extra channels up front so only RGB reaches the patch embed. * [Partner Nodes] feat(ByteDance): add Seedance 2.5 Draft mode (Comfy-Org#16529) Signed-off-by: bigcat88 <bigcat88@icloud.com> * chore: update workflow templates to v0.11.70 (Comfy-Org#16557) Co-authored-by: Purz <97489706+purzbeats@users.noreply.github.com> * Add HDR LogC3 and ACEScct to Convert Color Space node. (Comfy-Org#16541) * Fix HDR output issue with negative values in Convert Image Color Space. (Comfy-Org#16565) * Update sheetsage2 abc creation from upstream yue code. (Comfy-Org#16569) * perf(assets): replace pathlib prefix checks in the asset scan (Comfy-Org#16543) * Speed up the startup prune's owned-prefix check mark_contents_missing_outside_prefixes tested every live AssetContent row against every owned prefix with Path.is_relative_to, which walks the path's parents on each call: rows x prefixes x depth. At 9k rows and 150 prefixes that was 9.5s (15.5s with deeper output paths). path_prefix_matcher normalizes the prefixes once and checks each row with a normcase'd, separator-bounded str.startswith over a tuple, keeping is_relative_to's component bounds and platform case rules. The same case now takes about 0.04s, flat in prefix count and depth. * Move path_prefix_matcher next to the SQL containment predicate path_utils needs the same check for per-file tagging, and scanner_changes already imports path_utils, so the matcher moves to app.assets.helpers beside sql_path_under_prefix. * Speed up asset tag derivation during scans get_backend_system_tags_from_path checked every scanned file against every model base with Path.is_relative_to, which dominated the fast scan: 37s of build_asset_specs for 100k output files. Using path_prefix_matcher, the separator-bounded string check the startup prune already uses, brings that to about 7s. * Keep path_prefix_matcher's parity for paths starting with two slashes abspath keeps exactly two leading slashes, and pathlib treats that '//' as an anchor of its own, so Path('//server/f').is_relative_to('/') is False, but the string check accepted it. Prefixes are now split once by whether their anchor is '//', and a candidate is only checked against prefixes with the same anchor. The per-row check is still a single str.startswith. * Build tag-derivation prefix matchers once per folder config get_backend_system_tags_from_path built a path_prefix_matcher for input, output, temp and every model category on each call, so most of its cost was normalizing the same prefixes again for every scanned file. cached_prefix_matcher memoizes construction on the raw prefix tuple, which the callers pass as absolute folder paths; a folder-config change is a new key. 100k files, 58 model bases: tag derivation 81.8 -> 27.7 us/file, and build_asset_specs CPU 11.55 -> 6.40s. * State cached_prefix_matcher's absolute-prefix precondition The docstring presented absolute prefixes as a property of the callers. It is a precondition the caller must meet: folder_paths stores what it is given, and a relative prefix is resolved once, on first use, and then frozen. --------- Co-authored-by: guill <jacob.e.segal@gmail.com> * Mention some ComfyUI optimization details in README.

(Comfy-Org#16637) * fix(db): wait briefly for the database lock at startup (Comfy-Org#16602) * fix(db): wait briefly for the database lock at startup A relaunch can start while the previous process is still exiting and holding the lock. Wait up to 5 seconds for it to be released before treating the database as in use, and log how long the wait took. The lock is never taken from a holder. * fix(db): log the lock wait at info without guessing its cause * fix(db): say when startup waits for the database lock Log once before the wait instead of after it, so a lock that stays held explains the pause before the error. Document the wait in the docstring, and make the wait test release the lock only after the wait has started. * fix(assets): Start without the assets packages; --enable-assets reports what is missing and runs with assets disabled (Comfy-Org#16580) ComfyUI failed to start when the assets database packages (sqlalchemy, alembic, blake3) were missing, e.g. in a venv not re-synced after requirements.txt changed. That happened with assets off too, although that mode never needs them. - The asset imports in lifecycle.py, manager.py and server.py are guarded by db.py's existing dependencies_available() check. Without the packages, NoAssets registers no asset routes and temp cleanup still runs. - --enable-assets without the packages logs which packages are missing, prints the install command, and continues with assets disabled. - /view resolves blake3: filenames only when assets are enabled. Trade-off: if assets are turned off on an install whose saved workflows hold blake3: widget values, those previews return 404. Running such workflows already fails, since execution never resolves hashes. * perf(assets): keep the UI responsive during asset scans and rescan output by listing folders (Comfy-Org#16546) With --enable-assets, the scans that keep the asset database in sync could starve the web server's event loop and burn CPU on large libraries. Three changes: - First scan yields the GIL. The loop that derives names and tags for new files now sleeps briefly every 2 ms of work, so the event loop keeps running. At 51k files, time to a usable UI on the first run drops from 4.7 s to 2.0 s (1.5 s with assets off); the first scan takes about 3% longer. (was Comfy-Org#16546) - Output rescans list folders instead of stat'ing every file. The post-prompt output rescan compares directory listings against the database instead of stat'ing each catalogued file. That per-file stat was 70–95% of the rescan's cost: ~5.8 s per rescan at 200k outputs on local SSD, ~57 s at 10k on NFS. Any row the listing can't vouch for gets an individual stat before it is retired, and only "file not found" retires it: case-insensitive or normalizing filesystems, hidden folders, folders that fail to list, symlink aliases, and permission or I/O errors keep their rows. The one behaviour left to the next full scan is a file overwritten in place under the same name. (was Comfy-Org#16599) - Rescan loops pause. The listing and comparison loops pause every 10 ms of work, so prompts start and the UI stays responsive during a long rescan. At 200k outputs, without this a prompt could wait ~1 s to start. This costs 7–15% more rescan time. (was Comfy-Org#16600) Assets-only: none of this runs with assets off. * Speedup generation on qwen3.5/3.8 with long contexts.

(Comfy-Org#16663) Default CRF is now 18 on h264 and 24 on AV1. * feat: add DynamicGroup widget input (Comfy-Org#16260) * fix(assets): don't let a model category that can't be listed abort the scan (Comfy-Org#16658) folder_paths.get_filename_list raises when a folder it cached earlier has gone away (or on an OSError other than not-found), and collect_models_files let that abort the whole asset scan, so nothing in models, input or output was catalogued. Fall back to a fresh listing of the category, which skips a folder that's gone; if that raises too, skip the category with a warning and scan the rest. * fix(assets): recover records when a drive comes back with hashing off (Comfy-Org#16646) * fix(assets): recover records when a drive comes back with hashing off A scan that runs while a drive is offline marks every row on it missing. With hashing off (the default), nothing could recover those rows when the drive returned, so the scan created new records and the user's names, tags, metadata and job links stayed on the orphaned originals. - With hashing off, a file that reappears at a path no live row occupies recovers the missing row there whose size and mtime match exactly. If several match, the newest recovers. Hashing on is unchanged. - A reference stat that fails with an I/O error other than not-found leaves the row live, as the output listing rescan already does. - seeder.marked_missing is emitted per root when a fast scan marks rows missing, and scan_completed carries missing_marked_count and recovered_count. * fix(assets): read recovery candidates before the write transaction; count recoveries only once committed * test(assets): a pruned model folder recovers its records when it is registered again * fix(assets): never recover a missing row whose records were all deleted * docs(assets): scope the multiple-match rule to hashing on * docs(assets): only new content splits a same-path edit * test(assets): scan_completed carries nonzero missing and recovered counts * perf(assets): let the partial live-path index serve the hashing-off recovery check Written as IS 0, the check that no live row occupies the path scanned asset_contents once per recovered file, inside the batch's write transaction. At 50k rows that stretched each batch's lock window to about 2.5s and made concurrent output registrations time out. * ci: run the checks against master * test(assets): import folder_paths at module level * Fix crash when selecting int8 or int4 cache in qwen image 2.1 (Comfy-Org#16667) * [Partner Nodes] feat(Anthropic): add Sonnet 5.5 model (Comfy-Org#16647) * [Partner Nodes] feat(Anthropic): add Claude Sonnet 5.5 to the Claude node Signed-off-by: bigcat88 <bigcat88@icloud.com> * [Partner Nodes] feat(Anthropic): allow max_tokens down to 1024 for Opus 5.5 and Sonnet 5.5 Signed-off-by: bigcat88 <bigcat88@icloud.com> --------- Signed-off-by: bigcat88 <bigcat88@icloud.com> * [Partner Nodes] feat(Ideogram): add Ideogram 4.5 text-to-image, edit and precise edit nodes (Comfy-Org#16689) Signed-off-by: bigcat88 <bigcat88@icloud.com> * Fix minimax vae offload issue.

From about 500 prefixes every models scan failed with "Expression tree is too large" and the catalog stayed empty. Run the prefix filter in batches of at most 200 prefixes and merge the results, deduping rows that nested or overlapping prefixes put in more than one batch. With 200 prefixes or fewer the statement is unchanged. The enrichment candidate query merges each batch's keyset page, which yields the same page a single statement would. * fix(assets): filter enrich candidates in one pass above one prefix batch Paging each prefix batch separately made every page scan to the end of the table for any batch with few matches, which is quadratic in catalog size. Above one batch, read the candidates in id order once and apply the same prefix test in Python, stopping at the page limit. At 200 prefixes or fewer the statement is unchanged. Run the many-prefix tests under a 999 bound-variable cap too, the limit of SQLite before 3.32, which each 200-prefix batch stays under. * fix(assets): yield the GIL while filtering enrich candidates in Python Above one prefix batch the enrich candidates are filtered in a Python loop, which could hold the GIL across many rows outside the prefixes. Yield it per row as the other scan loops do, so the UI stays responsive. * Revert "fix(assets): yield the GIL while filtering enrich candidates in Python" Measured, it bought nothing: with a 60k-asset catalogue at 450 and 2000 prefixes, p99 lateness of a 1 ms sleeper thread is the same within noise either way, because the Python work between 500-row fetches is short and sqlite3 releases the GIL during each fetch. The yield made the loop 30-90% slower. * test(assets): import db at module level in the many-prefix scan test * Update comfy-kitchen version to 0.2.37 (Comfy-Org#16738) * [Partner Nodes] chore(Luma): deprecate Ray 2 nodes (Comfy-Org#16741) Signed-off-by: bigcat88 <bigcat88@icloud.com> * chore: update workflow templates to v0.11.76 (Comfy-Org#16739) * Disable pinned memory automatically on integrated GPUs (Comfy-Org#16746) * Disable pinned memory automatically on AMD APUs APU VRAM is carved out of system RAM, so pinning host memory only takes RAM away from the GPU. Detect AMD integrated GPUs and treat them as if --disable-pinned-memory was passed. dGPUs and the flag are unchanged. * mm: generalize is_integrated pin disable check to all cuda --------- Co-authored-by: tvukovic-amd <tvukovic@amd.com> * feat(assets): report scan CPU and paused time, and classify scan failures (Comfy-Org#16719) seeder.scan_completed reported only elapsed_ms, which is wall-clock time and includes every pause taken while prompts ran. It now also carries: - cpu_ms: the scan thread's CPU time (time.thread_time()). - paused_ms: time blocked at the pause gate, summed across pauses. - dirs_listed_count: directories the input/output walk or the output rescan's folder listing listed. - files_statted_count: os.stat calls on files in the scan's per-file loops (reference sync, the listing check, discovery, admission, seed, watch list and enrich). Scan failure events carried only the exception class, so every SQLite failure read as OperationalError. seeder.scan_failed, batch_insert_failed and scanner.{fast_scan,temp_sync,mark_missing,stat,watch_stat,watch_seed} _failed now also carry error_kind, one of a closed set: expression_tree_too_large, too_many_variables, database_locked, disk_full, disk_io, unable_to_open, database_corrupt, permission_denied, file_locked, read_only, other. It is a closed enum rather than a scrubbed message because str() of a SQLAlchemy error includes the statement and its bound parameters, which are file paths. Classification reads SQLite's result code where the driver exposes it (Python 3.11+), then SQLite's fixed message on the driver exception (exc.orig), then errno and, on Windows, winerror. Co-authored-by: guill <jacob.e.segal@gmail.com> * fix(assets): don't take the database lock when assets are off; warn when it's held (Comfy-Org#16742) * fix(assets): don't take the database lock when assets are off An assets-off ComfyUI no longer initialises the database or takes its lock, so it can't block a later assets-on start on the same install. If another process holds the lock, it prints a startup warning saying a future version will refuse to start the second instance, and keeps running. * fix(assets): never let the lock check stop startup; tighten the lock tests * fix(assets): keep the lock check's release inside its guard * fix(assets): reword the shared-database startup warning * Echo the Create Bounding Boxes background as a UI preview (Comfy-Org#16636) * perf(assets): let the partial live-path index serve live-row-at-path lookups (Comfy-Org#16659) * perf(assets): let the partial live-path index serve every live-row-at-path lookup SQLite will not use the partial index uq_asset_contents_path_live (WHERE is_missing = 0) for a predicate written is_missing IS 0, which is what is_(False) renders. Each "live row at this path" lookup therefore scanned asset_contents. register_executed_output and the seeder's hash-on recovery check ran that scan under the write lock, so the lock window grew with the catalog. Compare with == false() instead; the column is NOT NULL, so the result is the same. * test(assets): match the pre-3.36 SQLite wording of a table scan too * test(assets): stage the upload where the upload route does, so the move stays on one drive * [Partner Nodes] feat(ElevenLabs): add Eleven v4 and v4 Turbo models (Comfy-Org#16737) Signed-off-by: bigcat88 <bigcat88@icloud.com> Co-authored-by: Daxiong (Lin) <contact@comfyui-wiki.com> * [Partner Nodes] fix(OpenAI): remove transparent background for GPT Image 2 (Comfy-Org#16744) Signed-off-by: bigcat88 <bigcat88@icloud.com> * fix(assets): write the prune and offline marking in short batches so saves aren't locked out (Comfy-Org#16696) * fix(assets): batch the prune's and the offline marking's writes The startup prune, POST /api/assets/prune and the fast scan's marking step each held the SQLite write lock for their whole loop, so foreground output registration failed with "database is locked" during a large one. They now write in short batches, wait while a prompt runs between batches, and the prune endpoint runs off the event loop. * fix(assets): start the queued scan after a standalone prune, and recheck listing rows after a pause A prompt that ends while POST /api/assets/prune runs queues its output rescan; the prune now starts it when it finishes, as a scan does. The output-listing rescan takes its batch gate before reading the live rows, so a pause during the walk makes the marking re-stat what it retires. A cancel that arrives after the last batch no longer reports a finished prune as cancelled. * refactor(assets): drop the pause rechecks and the cancellable standalone prune Batching the writes is what keeps the lock short; the layers on top of it guarded edge cases that heal on the next scan. Batches now just commit, sleep about as long as they held the lock, and between batches honour the scan's pause/cancel checkpoint. The standalone prune is batched but not pausable, so it needs no cancel status or pending-scan handling, and the API contract is unchanged apart from running off the event loop. * fix(assets): start the scan queued behind a standalone prune; skip the last batch's yield POST /api/assets/prune now runs off the event loop, so a prompt can finish while it runs and queue its output rescan; the prune starts it when it ends, as a scan does. The batch loop checks for a stop before every batch and no longer sleeps after the last one. * test(assets): compare the set-mark paths in their stored, absolute form create_content stores os.path.abspath(path), which carries a drive letter on Windows, so the expected list must be built the same way. * fix(assets): a seed request during an API prune waits for it instead of 409 The prune now runs off the event loop, so POST /api/assets/seed can arrive while it holds the seeder; start() fails and the route answered 409, which a client reads as "a scan is already coming". A prune emits no scan events, so the refresh was lost. The route now waits the prune out and starts the scan, as it effectively did when the prune blocked the loop. * fix(assets): a cancel or shutdown stops a standalone prune between batches The API prune runs on a worker thread that interpreter exit joins, so a shutdown that only flagged it left Ctrl-C waiting for the whole prune. It now stops at the next batch once cancelled, and shutdown waits for that. A seed request also retries start() once after any failure, covering a prune that ends between the failed start and the check. * fix(assets): report a cancelled API prune as cancelled, not completed A cancel now stops a standalone prune between batches, so its response can carry a partial count; say so with status "cancelled" rather than presenting it as a finished prune. * fix(assets): a cancelled standalone prune leaves a queued scan queued Shutdown cancels the prune; starting the scan a prompt had queued from the prune's finalizer would run it on into teardown after shutdown returned. It now stays queued for the next scan's finalizer. * test(assets): assert the cancelled prune's outcome in the test thread pytest.raises inside the worker thread only produced a warning when the exception was missing, so the test could not fail on it. * fix(assets): wait for a prune on the loop, and close shutdown gaps around it A seed request during an API prune now polls on the event loop instead of holding an executor thread for the prune's length, and retries while a prune holds the seeder. Shutdown marks the seeder so a prune that has not started yet does not, both of its waits share one deadline, and the prune's idle flag is set even if its cleanup raises. * Add new attention and compiler stuff to AGENTS.md (Comfy-Org#16762) --------- Signed-off-by: bigcat88 <bigcat88@icloud.com> Signed-off-by: Tokha233 <61346912+Tokha233@users.noreply.github.com> Co-authored-by: Alexander Piskun <13381981+bigcat88@users.noreply.github.com> Co-authored-by: Daxiong (Lin) <contact@comfyui-wiki.com> Co-authored-by: Jialong(Bruce) Li <chelsealong@126.com> Co-authored-by: Simon Pinfold <synap5e@users.noreply.github.com> Co-authored-by: Jukka Seppänen <40791699+kijai@users.noreply.github.com> Co-authored-by: comfyanonymous <121283862+comfyanonymous@users.noreply.github.com> Co-authored-by: guill <jacob.e.segal@gmail.com> Co-authored-by: yulun <100981785+Big2Wheel@users.noreply.github.com> Co-authored-by: Purz <97489706+purzbeats@users.noreply.github.com> Co-authored-by: Davide bert <dc.bert@outlook.com> Co-authored-by: rattus <46076784+rattus128@users.noreply.github.com> Co-authored-by: comfyanonymous <comfyanonymous@protonmail.com> Co-authored-by: jaeone lee <89377375+jaeone94@users.noreply.github.com> Co-authored-by: Comfy Org PR Bot <snomiao+comfy-pr@gmail.com> Co-authored-by: Tokha233 <61346912+Tokha233@users.noreply.github.com> Co-authored-by: Deep Mehta <42841935+deepme987@users.noreply.github.com> Co-authored-by: tvukovic-amd <tvukovic@amd.com> Co-authored-by: Terry Jia <terryjia88@gmail.com> Co-authored-by: Kosinkadink <7365912+Kosinkadink@users.noreply.github.com>

Most image nodes send no preview to the frontend, so the canvas could not show a background produced by them. Save the first background image to temp and return it as background_images so the editor can fall back to it.
