Fixes from the review of the desktop import.
- A message another program holds is no longer recorded as deleted. Only a
real absence moves the import past it; anything else is tried again and
then reported as a failure, and the next run reads it.
- A resume that can't read some folders names them in a toast with a choice
to stop trying, keeps the job open and retries only those at the next start.
Files chosen by hand in the same dialog are named, since they can't come
back by themselves.
- A wipe or sign-out releases the job in the shell before the record goes.
Leaving the dialog without starting releases the confirmed files. Job
records are per account, and a start is refused while another window holds
that account's job.
- Dedupe goes by the bytes without state headers: a reused Message-ID of the
same length dropped a real message. Older records still count, so nothing
goes in twice.
- A lost connection on a folder or Email/import pauses instead of counting
towards the failures that stop an import.
- The taskbar goes through `lib/desktop/taskbar-progress.ts`.
Test changes: the taskbar test now renders the host, because its helper in
`local-import-job.ts` is gone, and the dedupe tests use `check`, which replaced
`keyFor` and `has`.
The import dialog in the desktop app can now find Thunderbird profiles and
Outlook PST files, show what it found and import what the user confirms.
Browsers behave as before.
- The bridge's `localImport` gives opaque handles and range URLs. The shell
asks natively before it looks, before it reads and before it goes on after
a restart.
- `lib/mail-import` gets a Maildir source and a per-file `folder`, so
Thunderbird's `.sbd` tree maps onto the account's folders. The PST worker
reads through a synchronous range XHR when there is no Blob.
- What was imported is remembered by Message-ID and size per folder, because
compacting a folder changes its checkpoint key and Email/import doesn't
dedupe. It runs from the dialog and on a resume.
- The job's record lives in IndexedDB, since Chromium writes localStorage too
late to survive a kill. Windows wait for the job's lock, so one takes over
when another goes.
- The desktop dialog says how long an import takes at the upload limit, warns
when Thunderbird is running, and turns down .ost files with the reason.
The engine used to be able to lose an import while offline: uploadBlob kept
the file on this device under a stand-in id and reported success. It now
passes `noHold`, Email/import is network only, an offline spell pauses without
using up a message's tries, and a device-only client stops at once. The same
fix applies to imports in the browser.
The lock is off by default, and an OS policy can require it and set the
timeout. It locks after a time without use counted across all windows and
tabs, on OS screen lock in the desktop app, and from Lock now.
Locking saves open composers, stops the outbox at its next message, closes
the store and stops its worker with every key, then reloads the page, so
nothing of the old page stays in reach. The new page holds the app back at a
Suspense boundary until someone unlocks. Pop-outs get no session while
locked, push notifications name nobody, and subjects leave plain storage.
One random lock key wraps each account's key as a layer. The PIN wraps the
lock key with PBKDF2 at 600,000 iterations, with a wait after wrong tries
that a reload doesn't reset. A passkey with PRF and the desktop's OS storage
wrap it too. Details and limits are in the decisions file.
A restored composer opened whatever the id named. Sending keeps the id, so its autosave would have destroyed the Sent copy, Send mailed it twice and Discard deleted it. It now needs the login in its address and a real draft, keeps its From with several accounts, and stays on the list if the server doesn't answer. A message from a bulwark:// link no longer marks itself read or sends a receipt. Native menus speak all 30 languages. Spellcheck dictionaries come from Google only after a yes, never in no-third-party mode.
A forced value could be got around from inside the app. Only a forced
value may now decide what's allowed: the keys that do are forced-only,
so a recommended one no longer acts as forced. With a plugin list a
package can name any id, so uploads are refused and only managed
plugins can match. A server taken off AllowedJmapServers stops its
accounts without signing out: client, push and sync stop, the switcher
drops them, restore and refresh answer 403 with the cookie kept, and
listing it again resumes with no sign-in. OAuth and SSO starts check
the list too.
- `policy.onWipeOfflineData` is gone from the bridge: main runs the wipe
- `KeystoreAllowedOrigins` added, and `POLICY_CONSUMERS` names who acts
on each key or who still owes it
- a Bulwark server's name must be plain after parsing, a wildcard in the
auth lists needs a domain of two labels
