The review found the store key readable from a copy of the disk. The
desktop app only added its OS layer with the lock on, the record from
before a lock stayed in LevelDB and opened the mail with no PIN, any
frame could unwrap the PIN record and guess at it, a lock left the key
in the renderer's memory, and a store waiting after a refused login went
to whoever signed in next under the same username@host.
- The desktop app wraps the store key with safeStorage, lock or no lock.
A record without the layer gets it at its next open. A refusal is said
out loud, and only a computer with no key store goes without, which
settings say. So do they for a browser, which has no such layer.
- A record that gained layers, and every record after a changed PIN, asks
for a new key: `sqlite3_backup` into a new file under a new key while
the store keeps working, one write to the record, then the old file
goes. A changed PIN makes a new lock key, since the old PIN's record
stays on disk too. The passkey and OS unlock go with the old key.
- `wrap` and `unwrap` come through `claim()`, and the key under the PIN
takes a secret from main, one counted trip per guess.
- A lock on the desktop ends the renderer rather than reload in it.
- A sign-in compares the waiting store's JMAP account and server first,
and wipes on a mismatch. The account id keeps its form: every store,
setting and server record of an account is keyed by it.
- The 30 days also run in an app that stays open.
Changes an existing assertion: turning the lock off now keeps the
safeStorage layer, by decision, so that test expects it to stay.
Eviction now goes by the base's signal: `storeLost` and the `store-reset`
notice, with `bulwark-store-opened` as the marker and `prune-files` for files
with no key. The storage page and the lost count hang off that. What a user
picks is stored under `bulwark-offline-scope`, the key `offlineScopeFor`
reads, and `email-snapshot` follows the base's rule. `OfflineEnabled` is read
from the desktop bridge when it's there.
The store took a scope only when it opened and acted on it only at a full
sync, so a lower cap left old mail on the device until something else
forced a resync. Now the engine applies a changed scope first, without the
network, and once a day as the window moves on.
Also tell the page whether an account's file was there when it opened, so
it can notice a store the browser deleted.
- `calendar-sync.test.ts` now syncs with `days: null`: its old events test
checks the calendar's own two years, and the calendar follows the scope now
- `page-side.test.ts`: the fake worker answers an open with what it found,
as the real one does
The IndexedDB cache, its crypto, the responder and the page-side sync
go. lib/offline keeps its structure, policy, wipes, sign-out gates and
notices; answers, the outbox and sync now live in lib/store, in a worker
behind lib/store/client/api.ts.
What users get besides that:
- every folder is kept, not just the Inbox and opened ones
- delete for good and empty trash work offline
- a change the server refuses, or that meets a message changed on
another device, is shown instead of dropped
- a send whose response got lost is looked up by a Message-ID fixed when
it was queued, then finished, submitted or sent again
- with the store on, a start paints from the local copy, then connects
An account the app drops by itself no longer wipes its data: only a
sign-out or an explicit removal does. The outbox of the old database
moves over once, in lib/offline/migrate-legacy.ts, and the old database
goes only after the store committed. `isNetworkFailure` now counts
timeouts and proxy 5xx. Sends and outbox requests are never answered
from the device.
Tests moved with the code: cache.test.ts and responder.test.ts are
replaced by lib/store/__tests__/, and review-fixes.test.ts, outbox.test.ts
and client-fallback.test.ts now run the real engine on node:sqlite.
Changed assertions: an uncertain send is looked up rather than left alone
forever, destroy and empty trash are queued rather than refused, and #9
(opened folders) became "a folder the server deleted goes", since all
folders are kept.
