The flush keeps one `outbox.dropOrphans` caller, the mail branch's daily
one with its 7 days, and drafts' own query says what's needed, so
`addHeldFileSource` and its test are gone. `unsentCount` counts local
drafts, and a draft a waiting send names counts once. The scope check in
`recordBlob` and the permanent-status rule moved to
`lib/store/mail/attachments.ts`, with tests.
Review of the offline drafts found these.
- Every new message gets new part ids and old ones die with it, so an
open composer failed with `blobNotFound` after a flush. The client and
the flush re-read the draft and re-point parts once. The fake now
gives new part ids, which is why `drafts.test.ts` and
`drafts-client.test.ts` compare file contents instead of blob ids.
- A Message-ID alone could destroy another client's message. A copy now
has to be solely in Drafts, with `$draft`, close to the attempt, with
the same subject and size, and what the lookup saw is the destroy's
base. Ghosts ride on the replacing row and only queue once it's up.
`drafts.created` no longer queues a copy that arrived for a replaced
row, so its test now expects the next flush to do it.
- Turning offline off asks about device-only drafts too.
- A kept file can't read back empty: chunks of a kept file are left
alone, and `keptBlob` and `heldFile` refuse pieces that don't add up.
- A flush stopped by a passing failure tries again, the banner shows
waiting drafts, and under the flush lock a `sending` row counts as
left by a dead tab at once. A lookup refused for good no longer stops
the outbox.
- `FetchTransport` streams downloads and reports a broken transfer as
interrupted, so one bad file doesn't end the pass.
- Raw messages come after every file, only into free room, and a file
needing room pushes them out first.
- An old version in another login stays until the new one is up. An
online send of an unflushed stand-in still removes its submission.
A draft saved offline now stays on the device under a stand-in id and
goes to the server by itself when it's back. Until now every save was
refused and the composer showed "not saved".
- `lib/store/drafts`: one pending create per draft, however often it's
saved. A draft from the server edited offline is replaced by create,
then destroy, so a failure leaves a copy. Each create has a fixed
Message-ID, looked up in Drafts after a lost response. A refused
draft stays on the device with its error and can be opened. Changed
on another device: both are kept and the user is told.
- `JMAPClient`: stand-in ids in Email/get and Email/set resolve like
calendar's, also when answering from the device. A file attached
offline stays readable, and is uploaded before a save that names it.
- Held files and kept mail files are stored in 1 MB chunks. Orphans are
dropped at the end of a flush, counting what drafts need.
- `lib/store/mail/attachments.ts`: attachments, inline images and raw
messages per scope, newest first, after everything else in a pass,
with eviction that spares pinned mail and never sees held files.
- `mail.rawBlob` and `mail.rawStatus` for an offline export.
Changed test assertions: `outbox.heldFile` and `mail.getBlob` return
`blob` instead of `data`, so a file isn't held whole in memory. The
attachment tests ignore raw downloads, and mail-sync runs with
attachments off, because raw messages add a commit per message.
Review of the calendar store found writes that went missing, went out
wrong, or appeared twice.
- Writes with different scheduling flags stay separate and go out in
order. Merging them collapsed the two steps of an occurrence change, so
attendees who had answered got no mail, and "don't notify" went out to
everyone with a later RSVP.
- An edit made after a create's lost response is sent as an update. An
import of a uid the server has updates what differs.
- `createCalendarEvent`, `batchCreateCalendarEvents` and
`createCalendarTask` choose a uid before the first send, so a lost
answer online doesn't duplicate.
- The client resolves stand-in ids before the network, which covers an
open dialog once the server is back.
- A stale whole `recurrenceOverrides` map no longer erases overrides.
- A 4xx refuses that write and the queue goes on. `serverFail`,
`rateLimit` or an answer with no verdict retry instead of deleting.
- "This and all following" is refused offline with a clear message.
- A full list only drops what the server says it doesn't have. Sync adopts
a stand-in by uid. Reminder keys survive a stand-in becoming real.
Accounts the session no longer lists are forgotten.
Changed tests: the one asserting a sticky scheduling flag is gone, it
locked in the bug. Reminder keys now use the account and uid. Two flush
assertions drop `sent: 1`, because sync reads a lost write back first. The
two-account id test uses a listed account, as unlisted ones are removed.
An existing assertion changes: resuming a full pass now starts from the last id seen rather than a position, since positions shift with every deletion.
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.
Adds a `calendar` area to the local store. It syncs calendars, participant
identities, events and tasks as masters, through CalendarEvent/changes,
and answers Calendar/get, CalendarEvent/query, /get and /set from SQLite
when the server can't be reached.
- A range query gets series in both client modes, with their overrides,
and the calendar store expands them as it does for an older server.
- The synthetic-id probe gets the verdict from the last sync, so a client
started offline behaves the same once the server is back.
- Create, edit, delete and RSVP queue in `calendar_pending`, one merged
row per event, and go out through `calendar.flush` or the next sync.
A create finds itself by uid after a lost response.
- A write the server refuses, or one on a value the server changed, goes
to `calendar.conflicts`.
- `lib/store/calendar/reminders.ts` lists upcoming alerts with keys that
don't depend on synthetic ids.
