* fix(config): report settings persistence failures (#220) Settings saves now go through one serialized config store (py/config_store.py). A commit re-reads config.json under a process lock, applies the change to a copy and replaces the file atomically (temp file beside it, fsync, close, os.replace), so a failed write leaves the old file in place. POST /prompt_manager/settings commits first and only then publishes the values at runtime. A write failure is 500 config-write-failed, an unparseable config.json is 409 config-unreadable (the file is kept instead of replaced) and a stale expected_revision is 409 settings-changed. A save reports persisted, revision, runtime_applied and restart_required_fields; GET adds the revision. Only submitted keys are written; other sections and the CivitAI key are kept. * fix(lora): report integration save failures (#220) POST /prompt_manager/lora/enable commits integrations.lora_manager through the config store and publishes the runtime values only after config.json holds them. Before, it set the runtime values, rewrote the whole runtime config (dropping sections it did not know) and reported success even when the write had failed. A write failure is 500 config-write-failed and changes nothing at runtime; an unparseable config.json is 409 config-unreadable. The body goes through the capped JSON reader and the flags must be booleans. A trigger word cache that fails to load is reported as persisted:true, cache_loaded:false. The CivitAI key is never echoed. The LoRA tests now write to a temporary config path. * fix(jobs): refuse legacy record-changing operations while a job runs The job registry gains admission classes. A records job is refused while any records or guarded job runs, a guarded job while a records job runs, and read jobs share only the one-job-per-kind rule. record_changing=True stays as the spelling of records. Job summaries add cancellable and admission, and a non-cancellable job ignores cancel. JobRegistry.hold() registers a running, non-cancellable job for a legacy-page operation and ends it when the request does. The legacy restore, maintenance, prompt cleanup, duplicate image delete, LoRA import and batch auto-tag routes hold as records; thumbnail generation (both routes) and thumbnail clear hold as guarded. A maintenance run of only read checks holds as read. So a restore during a scan, or a scan during a legacy restore, is refused with the running job named instead of interleaving; this closes the gap noted on #269. Refusals keep each route's shape: the JSON routes return the legacy 409 "<title> already running", and the thumbnail and LoRA streams send their existing error event. * test(lora): keep the preserved-section fixture free of secret values CodeQL flagged the fixture that writes the secret constant into a test config file as clear-text storage. The test only needs a marker value to prove the stored key survives a save. * fix(config): read under the commit lock and publish saves in write order - ConfigStore.read takes the commit lock, so no read handle is open while config.json is replaced (Windows refuses that replace). - os.replace is retried briefly on a Windows PermissionError (antivirus or indexer handles) before the save is reported as not written. - The temp file is written beside realpath(config.json), so a symlinked config keeps its link and a bind mount fails truthfully. - commit() takes a publish callback that runs under the lock after the write; settings and LoRA saves publish there, so two concurrent saves reach the runtime in write order and the runtime ends on the last one. - The concurrency tests now wait until the second caller is blocked on the lock (tests/lock_probe.py) before releasing the first. * fix(jobs): require an admission class, admit holds on entry, true Activity states - JobRegistry.start raises TypeError when neither admission nor record_changing is given, so a new job never runs as "read" beside a scan by omission. - hold() admits when its block is entered, so a hold that is never entered leaves no running records job behind; callers that answer a refusal in their own way check blocker() first, with no await before the block. - A held SSE operation that ends in an error event (thumbnail generation, legacy batch auto-tag) is listed as failed, and refused input (duplicate delete without paths, an unreadable thumbnail body) is answered before the hold, so it is not listed as a job. - Activity keeps a job's cancellable flag (true when an older server omits it) and shows Cancel only for a running, cancellable job, in Recent work and in the job view. A held legacy job no longer offers a Cancel that does nothing. * fix(admin): legacy pages show why a request was refused A job running in the workspace refuses the legacy record-changing requests, and a corrupt config.json refuses a settings save. The legacy pages now name the reason instead of hiding it: - LoRA import: the busy and failure frames carry status and progress, and the admin modal handles type "error": it shows the message, notifies and closes, instead of staying on "Initializing..." at 0%. - Legacy batch auto-tag: a refusal by another job is a 200 stream with one error frame ({type, status, message}), which both pages already render; a second batch keeps its exact JSON 409. - Gallery cache clear: a refused server clear shows the reason and stops before the success toast and the "Not generated" reset. - Admin settings save and maintenance show the reply's error ("config.json cannot be read...", "Scan for metadata already running") instead of "Failed to save settings" or "HTTP 409: Conflict". - Tests cover the read-only /maintenance branch: a read-only selection runs during a scan as a read hold; a mixed or default selection is refused. * refactor(api): move the settings routes out of admin.py GET and POST /prompt_manager/settings, their validation, the config commit and runtime publication, and the shared commit-failure reply now live in py/api/settings_routes.py as SettingsRoutesMixin, before S3 adds host fields there. No behaviour change: the same routes, payloads and status codes; admin.py drops about 300 lines. * chore(coverage): raise the floors of the frontend files this round touched admin.js, gallery.js, activity.mjs and activity-job-view.mjs, to their measured coverage. No floor is lowered. * fix(admin): the gallery starts no thumbnail status read while it leaves The gallery's startup thumbnail check runs one second after load. When that second ended while the page was leaving (CI, WebKit: the workflow test navigates from the gallery to the admin page), WebKit failed the new read with "Fetch API cannot load ... due to access control checks." and Playwright reported a page error. Like the admin page (#290), the gallery now has a page lifetime that ends on beforeunload and pagehide (and starts again on a back/forward restore). The check starts no read once it has ended and passes it as the read's signal. A page-clock workflow test that leaves before the second ends failed on both events, in Chromium and WebKit, before this change.
Viewer.js maintenance
ComfyUI serves the committed files in web/lib/viewerjs/. Node and npm are only
needed by maintainers and CI. Keep upstream files pristine; application behavior
belongs in web/js/, and theme overrides belong in comfyui-theme.css.
Install and verify
Use Node 24 or newer. From the repository root:
npm ci --prefix tools/vendor --ignore-scripts
npm run --prefix tools/vendor check
npm run --prefix tools/vendor test
node --test tests/js/*.test.js
npx --prefix tools/vendor playwright install chromium
npm run --prefix tools/vendor test:browser
On Linux, use playwright install --with-deps chromium when browser system
libraries are missing. The browser tests use synthetic images and mock the
ComfyUI API boundary; they run production viewer methods and the committed
Viewer.js JS/CSS, without a running ComfyUI instance.
check is read-only and fails if any JS, CSS, license, or provenance file differs
from the installed package. The manifest, lockfile, installed package, and asset
version banners must agree. The lockfile records npm's archive integrity;
provenance.json records the upstream source, package integrity, and SHA-256 of
each copied file. A normal npm ci --ignore-scripts verifies archive integrity.
Full-page workflows, frontend coverage gates, and required merge checks are
documented in TESTING.md. The viewerjs CI check runs both
the fixture tests above and the real-page workflows on every PR.
Update
npm run --prefix tools/vendor update
# Or select a specific stable version:
npm run --prefix tools/vendor update -- --version 1.15.2
The command installs an exact version with lifecycle scripts disabled and copies
dist/viewer.min.js, dist/viewer.min.css, and LICENSE. It writes deterministic
provenance with no timestamps. Repeat the checks above and commit the manifest,
lockfile, and all vendor files together. To regenerate files from the current
pin without changing versions, run npm run --prefix tools/vendor sync.
Automated update PRs
Update vendored Viewer.js checks npm's stable release daily at 07:30 UTC and
supports Actions → Update vendored Viewer.js → Run workflow, with an optional
version. It tests the generated update before opening deps/viewerjs-X.Y.Z.
Existing open or closed PRs for that release are left alone. A failed test does
not publish a branch or PR. Changes require review; the workflow never merges
or approves PRs.
The organization and repository must enable Actions → General → Workflow
permissions → Allow GitHub Actions to create and approve pull requests.
Keep default workflow permissions read-only. Only the update job requests
contents: write, pull-requests: write, and actions: write.
The workflow uses GITHUB_TOKEN; no personal token is needed. Because bot-token
pushes do not normally trigger other workflows, it explicitly dispatches the
read-only Viewer.js vendor and compatibility workflow on the update branch.
Both workflow files must be merged into the default branch before scheduling or
manual dispatch becomes available.
Compatibility checklist
Check gallery grid/list views, navigation across 100-image windows, metadata, slideshow/fullscreen, keyboard navigation, Escape and focus cleanup. Check the admin gallery/filmstrip and tag viewer. On touch devices, test long swipes, short drags, and pinch/rotate gestures. Confirm the ComfyUI theme remains usable.
The gallery keeps its bounded viewer and custom slideshow. Upstream navbar windowing is not a replacement for bounding the supplied image list: native slideshow playback can still preload every supplied original. Review new preloading defaults, gesture behavior, CSS changes, and any adapter use of Viewer.js internal methods before adopting another release.
Shared ComfyAssets test tooling
The exact toolkit commit archive in package.json / package-lock.json supplies
host orchestration and coverage helpers. comfyui-host.mjs is PromptManager's
configuration adapter; keep reusable lifecycle changes in the toolkit source.
The existing npm scripts remain the public maintainer entry points. See
TESTING.md for the managed real-host matrix and update policy.
Shared ComfyAssets browser controls
Prompt Manager (Classic) consumes the same pinned toolkit's browser controls.
The node identifier remains PromptManager; existing workflows, sockets, and
immediate result selection are preserved. PromptManager Text is unchanged.
Committed assets in web/js/shared/toolkit/ work without npm or KikoTools installed.
Maintain common controls in ComfyAssets Toolkit,
then update the exact archive pin and lockfile here. Regenerate using
npm run --prefix tools/vendor sync:toolkit; npm run --prefix tools/vendor check
verifies both Viewer.js and the toolkit without rewriting files. The toolkit
distribution includes its license, source history, archive integrity and per-file
hashes. Do not edit its copied files directly. Classic's controller and layout
remain in web/js/classic-node.js and web/js/classic-node.css.
Run the frontend coverage/browser suites and managed Classic/Nodes 2.0 matrix after updates. Shared modules participate in the frontend coverage gate. Pixaroma's reusable framework inspired this architecture; no Pixaroma code, styles or assets are included.
