`supportsSharing()` required `urn:ietf:params:jmap:principals:owner`,
which Stalwart advertises nowhere; its session only has `principals` and
`principals:availability`. The file menu therefore never showed
"Sharing & access", and `getPrincipals()` returned nothing, so the
calendar share sheet had no one to offer either.
- Gate sharing on `urn:ietf:params:jmap:principals`, like the webmail's
`supportsPrincipals()`.
- Keep `principals:owner` out of FileNode requests unless the server
advertises it, since an unknown capability in `using` fails the whole
request (why the gate had been tied to it).
- Page the principal lookup by `maxObjectsInGet`, as the webmail does:
one unbounded `Principal/query` fed every id to `Principal/get`, which
the server refuses once the directory has more than 500 entries.
`updateFileNode` and `deleteFileNodes` only looked for `notUpdated` and
`notDestroyed` in the first method response. A method-level `error`
reply (e.g. `forbidden`) has neither, so a refused rename, move or delete
reported success and the Files tab silently refreshed to the old state.
Every `FileNode/set` in `src/api/files.ts` now goes through
`requireMethodResult`, so the error reaches the existing alert in the
Files screen and the share sheet with the server's description.
The Files tab read the whole drive with `FileNode/get ids:null`, which
Stalwart silently caps at `maxObjectsInGet` (500 by default). Anything
past that, including folders created after the first 500 files and
everything inside them, never showed up, both for the own drive and for
shared accounts.
A full first page now counts as truncated, as in the webmail: the
remaining ids come from paging `FileNode/query`, are fetched in
`maxObjectsInGet`-sized `FileNode/get` batches packed into as few
requests as `maxCallsInRequest` allows, and parents that are still
unknown afterwards are fetched by id, which recovers folders on Stalwart
before 0.16.6 where the query returns files only. If the paging fails,
the first page is kept as before.
Adding a second account through the server's own OAuth opened the
authorization endpoint in the shared system browser with no `prompt`,
so the identity provider found the session of the account that was
already signed in and quietly handed back the same user.
When adding an account, the PKCE flow now sends
`prompt=select_account` like the webmail does (5771a213), or
`prompt=login` when the server's metadata lists no account picker, and
on iOS it runs the auth session ephemerally so the browser's cookies
don't carry over. The webmail hand-off gets the ephemeral session too.
Android's Custom Tabs have no private mode, so there the prompt is the
only guard.
With "Always send" the banner's auto-send ran in every page the viewer
pager keeps mounted, so opening one message also answered the receipt
requests of its unseen neighbours. The receipt is imported into Sent
before it is submitted, so a refused submission left a "Read: ..." copy
there, and the failure cleared the per-instance guard, so the next
render or remount imported another one.
- the pager marks the page on screen `active`, and the banner only
auto-sends there
- an automatic receipt is tried once per message per session, keyed by
account and id, so a failure or a remounted page does not send again
- `sendReadReceipt` destroys the imported copy when the submission
fails, which also covers the manual "Send receipt" button
The read receipt is assembled as raw RFC 5322 text, and every header
value in it comes from the message being answered. Stalwart returns
subjects already RFC 2047-decoded, so a sender could hide CRLF in an
encoded-word subject (or in the Message-ID or
Disposition-Notification-To) and have it interpolated verbatim. That
let them add headers such as Reply-To, or a whole body, to a message
the user's own account files in Sent and submits. `encodeHeaderWord`
passed any pure-ASCII value through untouched, CR/LF included.
Port the webmail fix: free-text values go through
`stripHeaderControls` (controls collapse to a space, then RFC 2047 if
non-ASCII), address-like values and message-ids through `headerAtom`
(controls and whitespace removed), and the From display name is quoted
when it uses specials.
