fix(storage): make factory-reset recovery deterministic (#591, #593) - #592
fix(storage): make factory-reset recovery deterministic (#591, #593)#592qnbs wants to merge 3 commits into
Conversation
…eload Fixes #591. ensureWelcomePortalEntry()'s Factory-Reset recovery flow (PR #590) necessarily navigates to Settings before triggering the reset, which writes #/settings into the URL via pushHash(). wipeAllAppData()'s final window.location.reload() preserves that same URL, and useApp.ts's readInitialView() reads the hash (then the 'view' query param) with higher priority than checking whether a project even exists -- so a genuinely successful data wipe can still reboot straight back into the pre-reset view instead of the WelcomePortal. Root-caused via the actual Playwright trace/accessibility-snapshot artifacts from two independent CI runs: the console-log timeline proved the wipe itself succeeded (no persisted-project rehydration message after reload), ruling out an IDB-deletion race -- confirmed separate from and unrelated to #589 and to PR #583's IDB reset-gate work (neither hooks/useApp.ts nor services/deepLinkService.ts is touched by #583). sanitizeViewCarryingUrlState() strips the hash and the 'view' query param via history.replaceState immediately before the real reload, preserving unrelated query/path state and the existing reload timing. Does not touch normal deep-link priority for ordinary navigation.

This PR correctly fixes the factory-reset URL state bug described in issue #591. The implementation is clean and well-tested.
Changes Reviewed:
- factoryResetService.ts: Added
sanitizeViewCarryingUrlState()to strip hash andviewquery parameter before reload, fixing the bug where reset would redirect back to the pre-reset view - factoryResetService.test.ts: Added comprehensive regression test verifying URL sanitization happens before reload and preserves unrelated URL state
- README.md: Updated test count badges (7357+ → 7358+)
Strengths:
- The fix is correctly positioned in the execution flow (after IDB/cache clearing, before reload)
- Test coverage includes call order verification to ensure sanitization precedes reload
- Edge cases are properly handled (try-catch prevents URL sanitization from blocking reset)
- The regex-based cache filtering and Tauri data clearing remain unchanged and correct
No blocking issues found. The implementation aligns with the PR description and successfully addresses the root cause where readInitialView() reads URL state before checking project existence.

…nd stop reserializing unrelated query state Two fixes, both discovered during #592's own validation: 1. services/factoryResetService.ts: url.searchParams.delete('view') + reading url.search back reserializes every retained query parameter via URLSearchParams.toString(), not just the one being removed -- e.g. turning a raw %20 into +, or a bare flag ?foo into ?foo=. Replaced with a string-level stripViewQueryParam() that removes only the view key, leaving every other parameter's raw encoding untouched. (Valid Cubic P3 finding on PR #592.) 2. Fixes #593. index.tsx's visibilitychange handler (and the desktop quit-flush, and register-sw.ts's update flush -- all three funnel through flushPersistedState()) fires on window.location.reload() itself, since a reload triggers visibilitychange before the page actually unloads. wipeAllAppData() doesn't stop the running app or its listeners during the 300ms settle window before that reload, so this flush can reopen and repopulate the IndexedDB database it just deleted with the stale, pre-reset in-memory state -- settings appear to reappear (a write far enough along to survive the unload) while the project usually doesn't (interrupted first, later in the same Promise.allSettled), producing exactly the 'settings-only persisted state' shape that makes index.tsx's isNewUser = !preloadedState false and skips the WelcomePortal. Confirmed via trace/console-log evidence: no project-rehydration log after the reset-triggered reload (ruling out an IDB-deletion race), yet the app boots into the Dashboard with a synthetically-seeded placeholder project -- exactly what useProjectBootstrapEffect produces once isPortalActive is (wrongly) false, which only happens if some persisted state, even settings-only, was found. isFactoryResetInProgress() (factoryResetService.ts) is set before any wipe work starts and guards flushPersistedState() itself, so all three call sites are protected by one change. Resets back to false if the reset itself fails and never reloads, so a failed attempt doesn't silently block every future save for the rest of the session. Confirmed independent of PR #583's IDB reset-gate architecture in mechanism (this closes one specific persistence-during-reset race with a minimal flag, not the general-purpose admission/generation/fail- closed gate #583 builds for every long-lived connection) but the same class of problem -- when #583 rebases, this invariant needs to be preserved inside its hardened reset implementation, not reintroduced separately.

Decode query keys before filtering.
stripViewQueryParam compares raw keys, but hooks/useApp.ts reads decoded keys with URLSearchParams.get('view'). Thus %76iew=settings survives reset and can restore Settings after reload. Decode each key for comparison and add coverage for encoded spellings.

Drain persistence work before deleting storage.
flushPersistedState() can enqueue saves before wipeAllAppData() sets resetInProgress. Because wipeAllAppData() does not await either persistence coordinator, those saves can run during or after deleteAllIndexedDBDatabases(). Await both coordinators after setting the flag, and add a deferred-save test.

…listeners The isFactoryResetInProgress() guard on flushPersistedState() (previous commit) only closed the visibilitychange/quit-flush race. Two OTHER onboarding-entry-precondition.spec.ts tests (unrelated to the Spanish- locale scenario the first fix targeted) still hit the identical #593 symptom on this PR's own discriminator CI run -- confirmed via the same trace-forensics method (no project-rehydration log after the reset, Dashboard rendered instead of the WelcomePortal). Root cause: app/listenerMiddleware.ts's own 1s-debounced project/ settings autosave listeners write directly via storageService, entirely bypassing flushPersistedState(). A debounce armed by a state change just before the Factory Reset navigation began (e.g. entering Settings) is still pending when wipeAllAppData() starts, and fires ~1s later -- inside or just past the reset's own delete-then-reload window -- repopulating the database the reset just deleted. Added the same isFactoryResetInProgress() check to addDebouncedListener itself (the shared factory every auto-save/auto-track listener in this file is built on), so project autosave, settings autosave, and codex auto-tracking are all protected by one change, the same way the prior fix centralized the flushPersistedState() call sites.

Summary
Fixes #591 and #593 — two real, independent bugs in
ensureWelcomePortalEntry()'s Factory-Reset recovery flow, both root-caused via the actual Playwright trace/accessibility-snapshot/console-log artifacts from CI runs during this PR's own convergence.Bug 1 — #591: stale view-carrying URL survives the reset reload
ensureWelcomePortalEntry()'s Factory-Reset recovery flow necessarily navigates to Settings before triggering the reset. Ordinary in-app navigation writes#/settingsinto the URL hash viapushHash().wipeAllAppData()'s finalwindow.location.reload()preserves that same URL, anduseApp.ts'sreadInitialView()reads the hash (then theviewquery param) with higher priority than checking whether a project even exists — so a genuinely successful wipe could still reboot straight back into Settings.Fix:
sanitizeViewCarryingUrlState()strips the hash and theviewquery param viahistory.replaceStateimmediately before the real reload. (A follow-up Cubic finding on this fix was also addressed — see below.)Bug 2 — #593: visibilitychange flush races the reset's own reload
After #591's fix, a different symptom appeared at the same final assertion: the app landed on the Dashboard with a synthetically-seeded placeholder project instead of the WelcomePortal. Traced via console-log timeline evidence (no project-rehydration message after the reset+reload, ruling out an IDB-deletion race) plus source tracing of
index.tsx's boot sequence:index.tsx'svisibilitychangehandler (and the desktop quit-flush, andregister-sw.ts's update flush — all three funnel throughflushPersistedState()) fires onwindow.location.reload()itself, since a reload triggersvisibilitychangebefore the page actually unloads.wipeAllAppData()doesn't stop the running app or its listeners during the 300ms settle window before that reload, so this flush can reopen and repopulate the IndexedDB database it just deleted with the stale, pre-reset in-memory Redux state.Promise.allSettled) — producing exactly the "settings-only persisted state" shape that makesindex.tsx'sisNewUser = !preloadedStateevaluatefalseand skip the WelcomePortal, landing on the Dashboard instead, whereuseProjectBootstrapEffectthen seeds a placeholder project title into the always-non-null default Redux project shell.Confirmed independent of PR #583's IDB reset-gate architecture in mechanism (this closes one specific persistence-during-reset race with a minimal flag; #583 builds a general-purpose admission/generation/fail-closed gate for every long-lived connection) but the same class of problem — when #583 rebases, this invariant needs to be preserved inside its hardened reset implementation, not reintroduced separately.
Fix:
isFactoryResetInProgress()is set before any wipe work starts and guardsflushPersistedState()itself, so all three call sites are protected by one change. Resets back tofalseif the reset itself fails and never reloads, so a failed attempt doesn't silently block every future save for the rest of the session.Bug 3 (review finding) — reserialization of unrelated query state
A Cubic P3 finding on the original #591 fix was valid:
url.searchParams.delete('view')followed by readingurl.searchback reserializes every retained query parameter viaURLSearchParams.toString(), not just the one being removed — e.g. turning a raw%20into+, or a bare flag?foointo?foo=. Replaced with a string-levelstripViewQueryParam()that removes only theviewkey, leaving every other parameter's raw encoding untouched.
