* test(browser): report a slow test reset with every thread's stack On #291 (run 39904288262, WebKit shard 2/2) one /__test__/reset {chronological_history} waited 16 s on its worker's server, with nothing on the server's stderr. The cause did not reproduce: the same worker's file sequence (library, library editor, tagging lifecycle, visual) at 2 CPUs three times, and WebKit shard 2/2 at 2 CPUs, kept every reset under 2 s. A reset still running after 2 s now reports, while it waits, every thread's stack (faulthandler), the default executor's threads and queue, the open connections and WAL size, and on Linux each thread's scheduler state and kernel wait channel. When it ends it reports the total and how long each executor call queued and ran. The lines carry a "pm-slow-reset| " prefix and the worker fixture copies them to the job log, so the next one shows up even in a test that passes. The report never reads another thread's connection. Reading even in_transaction on a connection busy in SQLite blocks on its mutex with the GIL held: a first version of this report froze the whole server until the 30 s busy timeout. A test holds a real write lock behind a reset and checks the server keeps answering while it waits. * test(browser): name each thread in the slow-reset stacks Before Python 3.14 faulthandler prints thread ids only, so the report now lists which name each id belongs to. CI on 3.10 to 3.13 failed the unit test that looks for the blocked thread by name. * test(browser): keep the slow-reset summary on a coarse clock On Windows the report timer can fire a few milliseconds short of the threshold, and the summary was then dropped. A reset that was reported now always gets its summary. The server test uses the plain reset, which the Windows jobs can seed, and puts the server stderr in its failure messages.
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.
