fix(desktop): open the window without waiting for the pane-sites clean-up - #9509
Startup no longer waits on the browser-pane migration's clean-up step. The window opens first, and the clean-up runs in the background.
The cookie copy stays before the window, so pane sites stay signed in on first load.
Why / Context
#9221 added movePaneSitesOnce, which startup awaits before the window is created. After it copies pane cookies to the pane session, it calls appSession.clearData({ origins }) to remove those sites from the app session. That call goes through the whole app session (HTTP cache, Service Worker storage, IndexedDB…), so its cost grows with the partition size, not the origin count. Nothing bounds it.
Reproduced in real Electron 44.10 with a clone of a real 2.6 GB Partitions/superset (1.1 GB Cache, 1.0 GB Service Worker):
clearData with 1,075 origins: 21 s. With 4,075 origins: also ~21 s.
Dev desktop on that profile (marker n/n, no .cleared), old code: window after 25 s, at the same moment .cleared is written. So the window is held until the clean-up finishes.
Both reporters got past it by creating pane-cookies-copied.cleared, which skips only that step. So on their profiles clearData did not finish at all, every launch. I could not make it hang forever locally. Either way the window must not depend on it.
How It Works
movePaneSitesOnce now only copies: it reads the app session's non-Paradev cookies, sets them on the pane session, and writes pane-cookies-copied as copied/total. It skips if either marker exists (users who applied the workaround keep working).
New clearMovedPaneSitesOnce does the clean-up. It runs only after a full copy, and writes .cleared only after clearData resolves. index.ts calls it after makeAppSetup (window created) with void …catch(log).
Safe if cut off: the clean-up only touches the app session, never the pane session. If the app quits mid-clear, .cleared is not written and the clean-up runs again next launch. The copy marker is still written only after every cookie was tried, as before.
Manual QA Checklist
Dev desktop, crafted profile (cloned 2.6 GB app partition, pane-cookies-copied = 2924/2924, no .cleared). Before: window (renderer page target on this worktree's DESKTOP_VITE_PORT, seen over CDP) after 25 s. After: window after 1 s. The clean-up still finished in the background and wrote .cleared at 26 s.
Fresh dev profile: window opens, migration markers written (0/0 + .cleared).
Cookie copy cost measured in Electron: 2,923/2,924 cookies in 0.2 s, so it stays on the startup path.
Testing
bun test src/main/lib/browser/move-pane-sites.test.ts. A new test "finishes the copy without waiting for the old sites to clear" (clearOldSites never settles) failed on the old code (Received: "hung"). After the split, a test covers copy without clear, plus a clean-up cut off part way that runs again without re-copying. 5/5 pass.
Then open Paradev again. No data is deleted. The app session keeps some old pane-site data that "Clear browsing data" won't reach.
Known Limitations
I did not find the exact profile state that makes clearData never resolve (vs. take ~20 s). The fix removes the dependency instead of tuning around one cause.
Summary by cubic
Fixes startup blocking in the desktop app where the pane-sites migration's clean-up step could delay the window by 20+ seconds or prevent it from opening on large profiles (T-1197, T-1198, regressed in #9221).
The cookie copy — fast at roughly 0.2 s for ~3,000 cookies — stays on the startup path so pane sites remain signed in on first load. The slow clearData over the whole app session now runs in the background after the window is created and retries on the next launch if it gets cut off.
Behavior notes
The clean-up only touches the app session, never pane cookies.
Profiles that already wrote the .cleared marker keep skipping both steps.
Written for commit 1348d9b. Summary will update on new commits.
Summary by CodeRabbit
Bug Fixes
Improved the handling of browser site data when moving pane data between sessions. Old site data is cleared only after copying completes successfully.
If clearing old site data fails, cleanup can be retried without copying the data again.
…n-up
Startup awaited movePaneSitesOnce before creating the window, and that
included appSession.clearData({ origins }) over the whole app session.
On a large session (2.6 GB here, mostly Cache and Service Worker) that
call blocks for 20+ seconds, and on the reporters' profiles it did not
finish, so 2.0.5 ran with no window (T-1197, T-1198).
The cookie copy (0.2 s for ~3,000 cookies) stays before the window so
pane sites stay signed in. The clean-up moves to its own function that
runs after the window opens and is not awaited. Its marker is written
only when clearData resolves, so a clean-up that is cut off runs again
next launch, and it only touches the app session, never pane cookies.
Cookie copying and old-site cleanup now run separately. Startup performs the copy first and launches cleanup after app setup. Cleanup checks that copying completed before clearing old sites, and tests cover retrying cleanup without copying cookies again.

Summary
Filter and copy pane cookies apps/desktop/src/main/lib/browser/move-pane-sites.ts
The new paneCookies helper filters out own-host cookies. movePaneSitesOnce copies filtered cookies and records the copied and total counts.
Gate and retry old-site cleanup apps/desktop/src/main/lib/browser/move-pane-sites.ts, apps/desktop/src/main/lib/browser/move-pane-sites.test.ts
clearMovedPaneSitesOnce checks the copy marker and counts before clearing origins. Tests cover separate cleanup calls and retrying cleanup without repeating the copy.
Run the two operations at startup apps/desktop/src/main/index.ts
Startup calls movePaneSitesOnce with the shared marker path, then launches cleanup after app setup with browser-history URLs and the old-site clearing callback.

The title "fix(desktop): open the window without waiting for the pane-sites clean-up" follows conventional commit format and matches the main change.

Explanation
The description covers the required template sections in substance. The 'What & why' section states the problem, the cause (movePaneSitesOnce awaited before window creation), and the fix (copy stays before the window, clean-up moves after makeAppSetup). It links issues T-1197 and T-1198 and the regressing PR #9221. The 'How I tested it' section gives manual QA steps with before/after timings, a fresh-profile check, unit test results, typecheck, and lint. The checklist is not ticked, and the template's conventional-commit title and CLA/maintainer-edit items are not confirmed in the description. Those are non-critical for this check. The description also has a workaround section and known limitations that go beyond the template.

Preserve cleanup origins when copying cookies.
If a copied cookie expires before cleanup and its origin is absent from history, cleanup omits that origin but still writes the completion marker. Old storage can then remain in APP_PARTITION, outside subsequent migration attempts and “Clear browsing data”. Persist the cleanup origins for use after copying and on retries.

Review verdict: minor issues. The split fixes the blocker. I reproduced it on base b77bc046: with a slow clear simulated at 90 s, the window opened at 91.6 s. At head 1348d9bb it opened at 1.2 s and the clean-up finished in the background. Tests, typecheck and CI all pass.
Findings (non-blocking):
apps/desktop/src/main/index.ts:718, move-pane-sites.ts:98-100: on the reporters' profiles clearData never finishes. With this change it starts again in the background on every launch, against the partition the renderer uses, and nothing records it: no duration log and no attempt cap. Suggest logging the duration and writing .cleared after N unfinished attempts.
move-pane-sites.ts:98: the clean-up now reads the app-session cookies again after the window is open. Non-own cookies that the live window sets, such as localhost in dev, get cleared too. Suggest working out the origins before makeAppSetup and running only clearData in the background.
Question: on your 2.6 GB profile, did the UI stay responsive during the background clear? The QA timed when the page target appeared, not whether the UI responded.

bun test src/main/lib/browser/move-pane-sites.test.ts. A new test "finishes the copy without waiting for the old sites to clear" (clearOldSitesnever settles) failed on the old code (Received: "hung"). After the split, a test covers copy without clear, plus a clean-up cut off part way that runs again without re-copying. 5/5 pass.bun run typecheck(apps/desktop): passbun run lint:fix: cleanWorkaround for users still on 2.0.5 / 2.0.6
Quit Paradev, then:
Then open Paradev again. No data is deleted. The app session keeps some old pane-site data that "Clear browsing data" won't reach.
Known Limitations
clearDatanever resolve (vs. take ~20 s). The fix removes the dependency instead of tuning around one cause.Summary by cubic
Fixes startup blocking in the desktop app where the pane-sites migration's clean-up step could delay the window by 20+ seconds or prevent it from opening on large profiles (T-1197, T-1198, regressed in #9221).
The cookie copy — fast at roughly 0.2 s for ~3,000 cookies — stays on the startup path so pane sites remain signed in on first load. The slow
clearDataover the whole app session now runs in the background after the window is created and retries on the next launch if it gets cut off.Behavior notes
.clearedmarker keep skipping both steps.Written for commit 1348d9b. Summary will update on new commits.
