findElectron() probed exactly one path, and got three things wrong at
once for anyone not on a hoisted POSIX install:
* It looked only under the REPO ROOT. This is an npm workspaces repo and
npm hoists a dependency only when nothing conflicts, so `electron`
installing into apps/desktop/node_modules is an ordinary outcome, not a
broken tree.
* It joined a bare `electron`. On Windows the dist file is
`electron.exe`, so the probe could never match there.
* Its PATH fallback spawned `which`, which is not a command on Windows,
so the fallback failed for a reason unrelated to whether electron is on
PATH.
The three combine into a misleading error: the suite refuses to start
with 'Run "npm install" from the repo root' on a tree that has electron
installed. Reproduced on Windows 11 against this repo, where
apps/desktop/node_modules/electron/dist/electron.exe exists and the old
body throws that message; the reporter on #88036 hit the same thing on
Linux and had to hand-symlink the package before the suite would run.
Resolution now asks the installed `electron` package for its own path
first (its main export IS the absolute executable, resolved from
path.txt and honouring ELECTRON_OVERRIDE_DIST_PATH), then falls back to
explicit dist probes for each root, then to PATH with the platform's
lookup command. The error message lists what was searched.
The rules live in e2e/electron-binary.ts so they can be unit-tested
without importing the Playwright runner, with the platform passed in
rather than read from process.platform: reading it would leave every
Windows rule untested on the Linux CI runner.
Wiring: the vitest `electron` project picks up e2e/**/*.unit.test.ts and
Playwright ignores the same pattern, so helper unit tests run in exactly
one runner and the specs are untouched.
Verified: 5 unit tests pass; mutation-checked one rule at a time
(hardcoding the binary name fails 2, reversing the probe order fails 1,
hardcoding `which` fails 1). tsc -p . and tsc -p tsconfig.e2e.json
clean.
This is the environment blocker called out in #88036, not its rendering
bug, so it is deliberately a subset.
Refs #88036
The desktop journal synchronously read, parsed, cloned, and rewrote one
aggregate localStorage value while streamed turns were repainting. Large
tool results and multi-session state could therefore block the renderer and
leave the app unresponsive, while the existing macOS diagnostic path lacked
a real native hide/restore regression check.
Store bounded recovery projections under per-session keys, migrate legacy v1
data once, isolate quota and storage failures, and preserve the newest
recoverable tail without allowing oversized writes to replace valid state.
Add a real Electron/CDP macOS-arm64 A/B harness with native visibility control,
renderer heartbeat and Settings/composer/transcript checks, plus focused
regressions. Keep bulk tool payloads, diagnostics, and the existing recovery
merge behavior out of the hot path.
Fixes#63047
Test 1 in skills/index.test.tsx pays the full cold-start cost (jsdom env
init + module transform + the @/hermes/@/store/profile import graph),
which pushed past vitest's 5000ms default under load — caught at 8871ms
on one run, 6.6s pure test time on another. Tests 2-4 are ~30-130ms
each because all that setup is already cached, so only test 1 was at
risk of timing out.
Bump the describe-level timeout to 15s. Verified with 10 consecutive
runs, 4 of which took 5.5-6.6s of test time and would have hard-failed
under the old 5s default.
Add vitest.setup.ts with IS_REACT_ACT_ENVIRONMENT=true + auto-cleanup,
and wrap render()/fireEvent() calls in act() across 8 test files:
- provider-config-panel.test.tsx: wrap renderPanel + fireEvent in act
- providers-settings.test.tsx: wrap renderProvidersSettings + fireEvent
in act
- use-prompt-actions/index.test.tsx: add actRender helper, wrap all 38
render
calls, wrap Harness handle methods (submitText/cancelRun/steerPrompt/
restoreToMessage) in act at the onReady callback level
- attachments.test.tsx: make renderWithI18n async + wrap in act
- skills/index.test.tsx: make renderSkills async + wrap fireEvent in act
- messaging/index.test.tsx: make renderMessaging async + wrap fireEvent
in act
- gateway-connecting-overlay.test.tsx: wrap all render/rerender in act
- preview-pane.test.tsx: wrap render calls in act, make tests async
Reduces act warnings from 44 to 4 (remaining are fake-timer + pre-render
store mutation edge cases). All 146 test files / 1180 tests still pass.
