return-to-picker.mp4

Follow-ups to #1626, the Startup Arguments "+N beta" pill. Closing Desktop Settings that was opened from the pill's "Manage beta features" (Escape, the close button or a backdrop click) now returns to that install's picker settings, instead of closing the popup and leaving the user to find their install again; Desktop Settings opened any other way still just closes. The rest lands the fixes from the review of #1626 that came in after it entered the merge queue (reply on #1626). The pill now asks once per open and per relevant change, never sends one install's args for another, keeps an open menu across a refresh, and drops a dead settings listener. Duplicated helpers for the schema revision, the launch command and the stored settings are now shared. The e2e checks read the pill's absence only once it has answered.

QA (Linux)

  • Independent QA passed the user-visible behaviour on a real build: return to the picker after opting out from Manage, the pill gone and back, switching installs, and other Settings entry points just closing.
  • e2e: 57/57 across the 4 pill specs and every spec that shares the touched helpers. The 4 pill specs passed 19/20 runs under CPU load (load average 40-56); the one failure is the restart-spec crash below.
  • Mutation-checked: returning to the wrong install or not at all, the preview ignoring the opt-out, an args commit asking twice, a stale schema or args, the session-key and answer-number rules, and the reload-count regressions each fail a test.

Known limitations

  • Test harness only, not the app: a shared e2e helper calls webContents.getURL() on every window from inside the app's main process; if one is mid-teardown, Electron segfaults (~1 in 60 restart-spec runs, also on main). No product code does this. Follow-up: look windows up by id via an e2e hook.
  • The restart spec rarely stalls: Restart is confirmed but the session never relaunches. It now fails within 30s with "restart never happened" rather than a 2-minute timeout. Tracked as a known flaky test; root-cause work is in progress.

📝 Walkthrough

Walkthrough

This change updates beta-argument preview inputs and pill refresh behavior, tracks settings freshness and session changes, and routes Desktop Settings dismissal back to the selected picker installation. It also updates settings-read handling and end-to-end test fixtures.

Changes

Beta-args preview and pill

Layer / File(s) Summary
Resolve preview inputs and revisions
src/main/lib/coreBetaAncestry.ts, src/main/lib/coreBetaInputs.ts, src/main/lib/comfy-args.ts, src/main/lib/coreBetaPreview.ts, src/main/lib/ipc/registerInstallationHandlers.ts, src/main/lib/ipc/sessionActions/launch.ts
Shared revision and SHA helpers feed schema lookup, launch discovery, and preview requests. Schema cache lookup uses the resolved revision.
Bound proofs and build previews
src/main/lib/coreBetaPreview.ts, src/main/lib/coreBetaAncestry.test.ts, src/main/lib/coreBetaPreview.test.ts, src/main/lib/coreBetaPreview.integration.test.ts
No new commit proofs start after the time budget. In-flight proofs may finish and cache answers. Tests cover proof timing, committed arguments, and relation-dependent grants.
Refresh beta-args pill data
src/renderer/src/views/comfyUISettings/BetaArgsPill.vue, src/renderer/src/views/comfyUISettings/settingsSectionsFresh.ts, src/renderer/src/components/settings/ComfyUISettingsContent.vue, src/renderer/src/stores/sessionStore.ts, src/renderer/src/composables/useComfyUISettings.ts, src/renderer/src/views/comfyUISettings/*test.ts, src/renderer/src/components/settings/ComfyUISettingsContent.test.ts, src/renderer/src/composables/useComfyUISettings.test.ts
The pill refreshes after session, argument, and schema changes. It waits for schema settlement, uses field arguments when settings sections are fresh, ignores stale responses, and tracks successful answers. The settings watcher reloads on session changes.
Exercise beta-args pill flows
e2e/support/betaArgsPill.ts, e2e/core-beta-args-pill*.test.ts
Shared helpers track answers, open Startup Arguments, and commit arguments. End-to-end tests cover grant display, commits, restart behavior, stopped installs, and request counts.

Desktop Settings picker return

Layer / File(s) Summary
Track the picker return target
src/main/popups/titlePopup.ts
Picker-originated Desktop Settings opens record the selected installation. Escape and backdrop dismissal return to its config tab when the host entry is available.
Validate dismissal and popup close behavior
e2e/core-beta-args-pill-stopped.test.ts, e2e/support/cdpPages.ts
Tests cover picker return after Escape and backdrop dismissal, plus closing settings opened through another route. The popup-close helper detects a picker that appears after a close request.

Settings and session state

Layer / File(s) Summary
Read stored settings consistently
src/main/settings.ts, src/main/settings.test.ts
A shared reader handles parsing, optional backup restoration, and read status. Beta-feature peeks use it without restoring backups; tests cover locked, malformed, and unreadable settings.
Track session changes in settings
src/main/popups/titlePopup.ts, src/renderer/src/stores/sessionStore.ts, src/renderer/src/composables/useComfyUISettings.ts, src/renderer/src/composables/useComfyUISettings.test.ts
The session store exposes a key based on the running instance start time. The settings watcher reloads on session changes and clears restart and error state when the same installation restarts.

Fake install process ownership

Layer / File(s) Summary
Configure fake install lifetime
e2e/support/fakeComfyInstall.ts, e2e/process-ownership.test.ts
The fake server exits when its parent process changes unless the fixture opts out. The process-ownership test enables the option.

Menu test description

Layer / File(s) Summary
Clarify menu test description
src/renderer/src/components/ui/BaseMenu.test.ts
The test description now states that the menu starts on the first enabled item after disabled items. The test body is unchanged.

Merge Risk: 🔵 Low · up to eb864

Popup teardown can still occasionally crash the Electron main process during e2e runs, interrupting the test run and requiring a rerun. This is a bounded test-workflow risk, not an established production-user failure.

Review comments at @e2e/core-beta-args-pill-stopped.test.ts:
- Line 264: Update both dismissal tests in the stopped-pill test suite to seed a
second installation with the same Startup Arguments content, then assert that
the visible settings section’s data-install-id equals INSTALL_ID after each
dismissal. Keep the existing content-visibility checks and use the same
assertion approach in both tests.
- Around line 293-296: Update the return-path test to wait for the
get-core-beta-args request to complete before asserting the result. Then assert
that the PILL element is absent directly, rather than relying on pillAriaLabel()
returning null, which also matches a present button without an aria-label.

Base automatically changed from synap5e/feat/beta-args-pill-v2 to main October 3, 2026 04:33
- The pill asks once per open, not twice. It refreshes on the session, the
  committed args and the args field's schema load, which settles on mount,
  on an install change and on each picker reopen. An install change only
  clears the old answer.
- Drop the pill's settings-changed listener. The picker's bridge has no
  such event, so it never fired; a picker reopen is what refreshes the pill.
- An open menu survives a refresh: the loading placeholder shows only while
  there is nothing to show yet.
- The pill counts the answers it has applied (`data-answers`), so a test can
  tell "answered, nothing to show" from "not answered yet".
- Revert the Tooltip hide-on-disable watcher. The pill no longer uses Tooltip.
- One session identity, `sessionStore.sessionKey`, for the pill and the
  settings watch. The watch no longer splits its key apart, and it seeds the
  install it is tracking so a restart right after mount still clears
  "Restart to apply".
- Share the schema revision fallback (`recordedRevision`), the schema cache
  check (`getComfyArgsSchema` uses the peek), and the settings file read
  (`readStoredSettings`). `getRunningSessionStartedAt` is required.

Tests:
- e2e specs share their selectors and helpers. Absence is read only once the
  pill has applied an answer newer than the open, however long git takes.
- The real-git tests clear inherited GIT_DIR and related variables from the
  environment itself, so the app's own git calls are covered too.
- The integration negatives pair each hidden grant with one that shows only
  if the preview proved the same relation.
- A test pins the launch's warning for a git check that threw.
Product:
- After an install switch the pill no longer sends the previous install's
  args with the new install's first request. They are omitted until the
  field shows the new install's value, and main reads the stored ones.
- Switching between running installs reloads the settings once, not twice.
  The session watch leaves an install change to the installation watcher,
  and it tracks the install and session explicitly.
- The preview stops starting proofs at its budget. The proof in flight still
  finishes and caches its answer.
- get-comfy-args uses the same launch-command split and recorded revision as
  the launch and the preview, so all three share one schema cache entry. A
  cache miss reads HEAD once. FULL_SHA_RE has one definition for ancestry
  and preview.

Tests:
- The cross-platform stopped-pill e2e is opted in, with a grant the install
  qualifies for, and reads absence only once the pill has its answer.
- The committed-args path is tested with a launch command built from the
  record it is given.
- The save and args-commit request counts hold over a quiet window.
- The peek's locked-primary and unreadable branches have their own tests.
- New tests cover reload counts on install switches and after moving between
  stopped installs.
- commitArgs is shared.
…ned from Manage

"Manage beta features" in the Startup Arguments pill switches the picker
popup to Desktop Settings. Closing Settings closed the whole popup, so the
user lost their place. Settings opened from the picker's settings now
records that install, and Escape, the close button or a backdrop click
reopens the picker on its config tab. Settings opened any other way still
just closes, and every open clears the return target.

The e2e close helper now closes at most twice, since the first close of a
picker-opened Settings goes back to the picker.
…2e popup only once more for it

From review:
- The Manage handler takes a return target only when the sender is the
  picker, so a Settings view that ever used the channel could not inherit a
  stale selection.
- The e2e close helper closes a second time only when the first close showed
  the picker, rather than waiting out a timeout. A popup that reappears for
  any other reason still fails it.
- The backdrop click in the test targets the title popup's backdrop
  specifically.
…nce only once answered

From review:
- The stopped spec seeds a decoy install, listed first and with the same
  Startup Arguments, and asserts the returned picker shows the original
  install.
- The opt-out return test reads the pill's absence only once no loading
  placeholder is showing, so it cannot pass before the answer arrives.

@synap5e synap5e changed the title fix(settings): return to the picker when closing Desktop Settings opened from Manage fix(settings): beta-args pill follow-ups: return to the picker from Manage, and #1626 review fixes Oct 3, 2026
- The config pane is keyed by install, so the pill remounts on a switch
  and its install-switch watcher never ran. It is gone. On mount the field
  can still show the previous install's args, so the pill sends args only
  once the value has changed since mount; until then main reads the stored
  ones.
- The settings session watch tracks the install and its session as two
  watch sources, so the previous pair comes from the watch itself.
- The opt-in peek no longer logs a malformed settings.json on every ask;
  loading still does. loadOutcome's doc is back above it.
- The e2e close helper closes a picker once, so a picker that ignored its
  first close fails; only Desktop Settings that returned to the picker is
  closed a second time.
- The answered-with-no-pill check compares against the pill noted before
  the open, so a remounted pill's counter is not read against another
  pill's baseline.
- settings.test shares the locked-primary spy and restores it after each
  test.

Include startedAt in the instance-started event.

Production _addSession stores startedAt but omits it from the event payload. The renderer stores that payload unchanged, so successive starts can both produce an empty sessionKey. The settings watcher can then miss a running-to-running restart.

Review comment at @src/renderer/src/stores/sessionStore.ts at line 80:
Update _addSession to include the stored startedAt value in the instance-started
event payload, so the renderer receives a distinct sessionKey for successive
starts and detects running-to-running restarts.

Taken in 408f418. _addSession and the seeded-session path now put the stored startedAt on instance-started. A broadcast test pins that the payload carries the same value as the session record. In practice the main window also sees each stop between two sessions, but the key should not depend on that.

Correction: reverted in 2f07f43. A later review found nothing reads startedAt on instance-started. The session key is read only in the picker popup, which takes startedAt from its own snapshot and never receives this event, so my earlier "main window" premise was wrong. The broadcast and its test are back to main.

- instance-started carries the session's start time, which the renderer's
  session key reads. Without it every session in the main window had the
  same empty key.
- The pill asks only once the field's first schema load has settled, so
  sections that land before it no longer get an empty preview.
- A failed request still shows nothing, but no longer counts as an answer.

🟠 High — Deleting the watch(() => props.disabled) block leaves nothing to hide a bubble that is already visible when disabled flips to true: useTooltip only consults canShow() inside show(), so the bubble lingers until the pointer leaves. Consumers do flip it reactively (ComfyUISettingsContent.vue tab tooltips via isTabLabelHidden, TruncatedText's :disabled="!isTruncated"), and an interactive bubble has pointer-events: auto, so the stale bubble can swallow clicks on whatever the trigger just opened. The two tests covering exactly this were removed in the same diff. Raised by 3 of 8 reviewers (claude-opus-5-thinking-max edge-case, claude-opus-5-thinking-max adversarial, gpt-5.6-sol-max adversarial).

Not taken. #1626 added this watcher for the pill, and the review of #1626 asked for its removal once the pill stopped using Tooltip, so this restores the behaviour from before #1626. Neither consumer that flips :disabled at runtime (TruncatedText, and the settings tab labels in ComfyUISettingsContent.vue) sets interactive, so their bubble keeps pointer-events: none and cannot swallow a click. It stays up until the pointer leaves, as it did before #1626.

🟠 High — Dropping immediate: true and gating on props.schemaVersion > 0 means a pill mounted after the parent's schema load has already settled (schemaVersion already non-zero, so the watcher never fires) never issues a request at all, and the onSettingsChanged subscription that previously provided a second trigger was removed in the same change. It also gates the running-install answer, which main serves from the in-memory session record (timing: 'session') and needs no args schema, behind a cold-cache python main.py --help round-trip (15s execFile timeout). Consider firing immediately when schemaVersion > 0 at mount, and not gating the session case.

Not taken. The pill cannot mount after its field's schema load has settled. It is a child of ArgsBuilderField, rendered on the field's own installationId. The field starts its schema load in the same setup (an immediate watch on that id), and the pane holding both is keyed by install, so every mount meets schemaVersion === 0 and gets the bump when the load settles. The onSettingsChanged listener was removed because it never fired in the picker popup, where the pill renders.

Waiting for the schema before a running install's answer is deliberate: the pill has one trigger path for every state. The launch already fills the schema cache for that revision, so it is normally a cache hit.

🟡 Medium — entry.returnToPickerInstallationId = returnTo is assigned unconditionally, but this channel's handler also runs for a sender whose kind is already global-settings. A Desktop Settings popup that re-invokes it computes returnTo = null and clobbers its own live return target, so the next Escape or backdrop click dismisses instead of returning to the picker.

Not taken: the case can't happen. The only sender on this channel is the beta-args pill (the picker settings' openGlobalSettings, via pickerSettingsApiShim). The pill renders only for an installationId, which Desktop Settings never has, so a global-settings entry never sends this channel and has no return target to lose. The beta notice and the deep-link router call openGlobalSettings from other renderers, which go through other handlers.

🟡 Medium — dismissTitlePopup reopens the picker on returnToPickerInstallationId without revalidating it against current installations. If the install is deleted, untracked, or hidden from the renderer while Desktop Settings is open, the picker reopens on a stale selection and stays blank, since later snapshots preserve the selected id.

Not taken. The return target is always the local install whose Startup Arguments held the Manage link (cloud installs have no launch args). While Desktop Settings is open, nothing in it can delete, untrack or hide a local install: hideCloudFromPicker only hides cloud installs. The popup's backdrop also covers this window's panel. So the target cannot go stale while Settings is open.

🟡 Medium — Making getRunningSessionStartedAt required on TitlePopupHostBindings and dropping the ?? {} fallback turns any binding object that omits it (partial test mocks, alternate hosts) into a runtime TypeError inside the snapshot broadcast path.

Not taken. The binding is required on purpose, so the compiler checks every registerTitlePopupIpc caller. The only objects that omit it are test doubles cast with as TitlePopupHostBindings. Those suites never reach the snapshot broadcast, and they pass.

🟡 Medium — requestTitlePopupClose keeps its own internal .catch, but titlePopupShowsPicker and the new expect.poll chains run unguarded: if the popup disappears between the visibility check and these probes, closeTitlePopupIfOpen now throws from a helper that used to be safe to call in teardown. Given this is the shared cleanup path for every title-popup spec, consider making the whole sequence tolerant of a popup that closed early. Raised by 1 of 8 reviewers (kimi-k2.7-code adversarial).

Not taken. Both probes are already guarded: titlePopupShowsPicker ends in .catch(() => false), and isPopupVisible ends in .catch(() => false). A popup that closes early therefore reads as hidden, which ends the poll successfully.

🟡 Medium — Both failure paths of the freshness guard silently degrade to the weakest check: a missing answersBefore entry falls back to { answers: -1 }, and notePill's .catch(() => -1) leaves the DOM untagged so noted is false — in both cases the threshold becomes answers > 0, which an answer from a previous open already satisfies because the picker stays mounted while hidden. The miss is easy to hit since titlePopupPage() returns a fresh WebContentsPage per call, so the WeakMap only resolves for the exact object openStartupArgs returned. Given the repo's zero-tolerance flake policy, prefer throwing on an unnoted pill over falling back. Raised by 2 of 8 reviewers (claude-opus-5-thinking-max edge-case, kimi-k2.7-code edge-case).

Taken in 095f69c. expectAnsweredWithNoPill now throws when there is no note for that page, instead of falling back. When notePill finds no pill it has nothing to tag, and the pill that later appears is a new mount, so any answer it applies is newer.

🟢 Low — notePill records data-answers before the open, so a request already in flight at that instant resolves during the open sequence and bumps the counter with a pre-open answer that expectAnsweredWithNoPill then accepts as newer. The new closeTitlePopupIfOpen makes this the common case rather than a rarity: it dismisses Desktop Settings by reopening the picker, which bumps the reopen epoch and starts a refresh immediately before the note is taken.

Not taken. Every caller takes the note after the state change it then asserts on, so any request still in flight at the note was issued after that change, and its answer reflects it. The Manage return case takes its note while Desktop Settings is showing, when the picker (and so the pill) is unmounted and nothing is in flight.

🟢 Low — The new overBudget early-exit abandons the remaining SHAs instead of letting the walk finish and warm the cache, so an install whose proofs exceed PREVIEW_PROOF_BUDGET_MS re-pays up to 5s of git/pygit2 work on every picker open, args commit and session change, and needs several requests before a grant can appear — and each new HEAD restarts the cycle.

⚪ Nit — schemaCache is still an unbounded Map keyed by installation id; entries are replaced rather than added per revision, so growth is bounded by install count, but nothing evicts entries for installs the user has since removed.

Demo at 408f418 (Linux, 50 s): Startup Arguments pill, then Manage, then Desktop Settings. Turning the beta opt-in off and pressing Escape returns to the same install's picker settings with the pill gone. Turning it back on brings the pill back, and switching installs keeps each install's own answer. (The file upload is attributed to Simon's account; GitHub only accepts uploads from a user token.)

return-to-picker.mp4

…eading pill absence

- The fake ComfyUI now exits when Desktop dies. It inherits Desktop's
  listening CDP socket, so an orphan left by a crashed run failed the next
  launch on that port. process-ownership opts out with outlivesDesktop,
  since its subject is that orphan.
- expectAnsweredWithNoPill throws when the pill was never noted, rather
  than falling back to a check an earlier answer would pass.
- The pill numbers its answers across the document and never resets, so
  a remounted pill's answers are always newer than any noted before. The
  e2e helper loses its DOM token and remount branch, a failed read throws,
  and opening Startup Arguments waits for that open's own answer before a
  test changes state or counts requests.
- The cross-platform pill spec no longer seeds ops flags on macOS, where
  the app's config dir is the real userData and the seed would outlive
  the run; its stopped case is Linux and Windows only.
- Revert startedAt on instance-started: nothing reads it. The session key
  is read only in the picker popup, which takes startedAt from its
  snapshot.
- Drop titlePopupReturnTarget: every open clears the return target, so the
  kind check guarded a state that cannot occur.
- The opt-in peek's readFailed guard was redundant; comments name the
  Storage tab as the picker's other link into Desktop Settings.
- The restart spec fails within 30s with "restart never happened" instead
  of a 2-minute timeout; the last stopped test reads absence only once
  answered.
…-then-other-open case

From the delta review:
- The backdrop return test opens the picker on the decoy and switches to
  the install before Manage, so a return to the install the picker opened
  on fails.
- "Opened any other way" now opens Desktop Settings from the panel while
  the Manage-opened one is still showing, so it exercises the clear on
  open rather than a target the close helper had already used up.
- The restart spec reads the pill after the commit only once it has
  answered for the committed args.
- Comments: the picker-only check on the Manage channel is defensive;
  the session watch's comment no longer claims the pill.
…urn guards

From the final design review:
- Restore Tooltip's disabled watcher and its tests (back to main). The
  settings tab strip disables a tab's tooltip when the tab is clicked
  under 640px; without the watcher the bubble stayed up until the pointer
  left and took the first Escape.
- The Manage handler reads the picker's selection directly, and the
  dismiss path drops its destroyed-parent arm: neither case can occur.
- "Opened any other way" opens the panel's Desktop Settings on another
  tab and waits for it before Escape, since the two opens come from
  different renderers with no ordering between them.
- The restart spec reads the pill's absence after the restart only once
  it has answered.
… install

From the delta review: the pill sent args only once the field's value
had changed since mount, to avoid sending the previous install's args
after a switch. That also dropped this install's own edit whenever the
pill remounted, such as on Back from the full args editor: main then
previewed the stored args before the save landed, and the wrong pill
stayed until the next reopen or edit.

The settings view now provides whether its painted sections belong to its
install, and the pill sends the field's value whenever they do; only while
another install's sections are still shown does main read the stored args.

Tests: the zero-answer check holds its request pending instead of relying
on scheduling, and the "only the pill asks" quiet windows start once the
sections re-read has reached main.
…y answer

From the delta review: the in-time answer test answered with two args, so a
delay that was never cancelled stayed hidden behind them. An empty answer has
nothing to hide it.
…pplied

From the final review: the window started when main received the re-read,
before the view applied it, so a re-ask caused by applying it could land
after the window on a loaded machine. The test now counts applied sections
responses in the popup and starts the window after the save's one.

P1 Badge Avoid scanning tearing-down WebContents by URL

When the restart spec closes or reopens the title popup while another WebContents is being torn down, this new enumeration calls getURL() on that object; the commit's stress results report that Electron can segfault here roughly once in 60 runs, and the surrounding .catch() cannot recover from a native-process crash. Resolve the popup through a stable e2e hook or retained WebContents id instead so this modified suite does not remain flaky.

Taken in eb8649c. The picker probe now looks up the popup by the webContents id that closeTitlePopupIfOpen already resolved (webContents.fromId), so this PR adds no getURL scan. The URL-scanning lookups that predate it (findWebContentsId, requestTitlePopupClose, and others in other specs) are tracked for a follow-up that resolves WebContents through an e2e hook; the PR description lists the crash under Known limitations.

🩺 Stability & Availability | 🟡 Minor | ⚡ Quick win

Skip destroyed WebContents before reading its URL.

findWebContentsId runs once before polling. The polling callbacks repeatedly call isPopupVisible and titlePopupShowsPicker, which call getURL() without checking isDestroyed(). In Electron 40.4.1, getURL() accesses native WebContents state that destruction clears, so this can crash the main process. A JavaScript catch cannot recover from that native crash. Skip destroyed candidates before each URL lookup, including the initial lookup and close-request lookup.

From the Codex review: the probe that tells a returned picker from a
closed popup scanned every WebContents with getURL, which can crash
Electron on one mid-teardown. The close helper already has the popup's
webContents id, so the probe uses it and adds no URL scan.

@coderabbitai on the outside-diff finding for e2e/support/cdpPages.ts:350 (guard every getURL() with isDestroyed()): not taken. That guard was tried on this branch, and the restart spec still crashed Electron inside the guarded findWebContentsId (1 of 30 runs), because isDestroyed() still reads false during teardown. The fix is to stop scanning by URL, which is tracked as a follow-up and listed under Known limitations. This PR no longer adds a URL scan (eb8649c).
