Sending mail through Bulwark could leave the delivered message stuck in Drafts
(keeping the $draft keyword) and never file a copy into Sent, with no error
shown, for accounts whose Drafts/Sent mailbox JMAP id is a purely-numeric
string (e.g. "0").
The post-send Drafts->Sent move is expressed as onSuccessUpdateEmail on
EmailSubmission/set using `mailboxIds/<id>` JSON-Pointer patches. Stalwart
up to 0.16.4 (observed on 0.15.5) rejects an Email/set PatchObject whose
pointer token is all digits -- e.g. `mailboxIds/0` -- with invalidProperties
"Invalid patch value", treating the token as a JSON-Pointer array index even
though mailboxIds is a JSON object (cf. RFC 6901 section 4; RFC 8620 section
1.2 warns servers against such interop-hostile ids). Because the move runs
only AFTER the EmailSubmission already succeeded, the message is delivered but
the filing update is silently rejected: the send code inspects only
`notCreated`, not the onSuccessUpdateEmail `notUpdated` result, so nothing
surfaces to the user.
Stalwart fixed the pointer parsing server-side in 0.16.5
(stalwartlabs/stalwart@175f34ea, jmap-tools 0.1.4 -> 0.1.5; a sibling symptom
was stalwartlabs/stalwart#2985). The client-side change is still worthwhile:
earlier Stalwart deployments remain in the wild, and a full-property
replacement both states the actual intent of the move and emits no per-id
pointer token that another server could mishandle.
Replace the per-id pointer patches at every post-send / undo-send move site
(send, scheduled send, raw-import send, reschedule, and restoreEmailToDraft)
with a full `mailboxIds` property replacement via a new mailboxIdsReplacement()
helper. This states the actual intent -- after the move the message should
belong to exactly the target mailbox -- and is immune to the pointer-token
bug. Every one of these sites moves a message that Bulwark itself placed
solely in Drafts (or, for undo, in Sent), so the replacement is
behaviour-equivalent. Note it is a replacement: a membership added to the
message by another client between creation and send is not preserved.
restoreEmailToDraft now always lands the message in Drafts only (previously,
when no Sent mailbox id was passed, it left the Sent copy in place); the demo
client is aligned with the same contract.
Add regression tests for the full-replacement shape, a numeric ("0") Drafts id,
and restoreEmailToDraft.
Follow-up (not included here): the send paths still ignore the implicit
Email/set `notUpdated` result of onSuccessUpdateEmail, so any other post-send
filing failure would remain silent.
Clicking Send while attachments were still uploading silently dropped
them from the outgoing message: every place that builds the outgoing
attachment list filters on att.blobId && !att.uploading, and the Send
button never accounted for uploads still in flight. Attach a few files,
hit Send right away, and the email could go out missing some of them
with no warning.
handleSend now detects pending uploads before validating:
- Send is disabled with an explanatory tooltip
(validation.attachments_uploading) while it waits.
- Once uploads finish cleanly, the send proceeds automatically - no
second click needed.
- If an upload FAILS while waiting, the send is aborted with an error
toast (validation.attachment_upload_failed) instead of silently
shipping the email without the failed attachment - the user may not
be looking at the composer to notice the red error chip.
- If the draft is closed or discarded while waiting, the pending send
is cancelled cleanly.
The wait/decision logic lives in waitForPendingUploads() in
lib/email-composer-utils.ts (returns completed | cancelled | failed)
with unit tests covering all three outcomes. Outgoing-attachment
call sites read the freshest state via attachmentsRef since the
render closure captured at click time won't reflect uploads that
finished during the wait.
Both new i18n keys added to all 20 locales under
email_composer.validation.
