The Files page UI sat at 0% throughout an upload because uploadBlob()
uses fetch(), which does not surface upload progress events. The store
set loaded=0 before the call and loaded=file.size after it, so users
saw the progress bar jump from 0% straight to 100% on completion --
and on slow connections (or large files) it appeared frozen.
Switch uploadBlob() to XHR when the caller passes onProgress or an
AbortSignal, so progress events from xhr.upload.onprogress can drive
the UI. Callers that don't pass either keep the fetch path so we
preserve the existing 401-retry behaviour in authenticatedFetch().
Wire the file store to pass both onProgress (updates uploadProgress
in real time) and the existing AbortController's signal (so cancel
now actually aborts the network request, not just the post-upload
createFileNode step).
uploadBlob() is part of IJMAPClient so the signature change is also
applied to the demo client (synthesises 0% then 100%).
* Added account selection for protocol links when multiple connected accounts are available, including mailto: links
* Added support for handling mailto: links in an already-open PWA/session instead of always opening a new tab
* Added webcal: protocol handling for calendar links
* Added account selection for webcal: links when multiple calendar-capable accounts are connected
* Added an import-or-subscribe choice for detected webcal calendars
* Added protocol handler settings for registering mail and calendar handlers and choosing the open mode
* Added service worker/session coordination for passing protocol requests between browser/PWA contexts
* Added tests and translations for the new protocol handler flows
Adds an Override toggle in the composer's From row. When enabled, name
and address become free-text inputs. Mail is still submitted through the
selected identity, but the outgoing message's From: header — and the
SMTP envelope MAIL FROM when different — is set from the override.
The existing "Auto-select Reply Address" setting is extended: if the
incoming message was addressed to an alias on a domain that matches one
of your identities but isn't itself an identity (classic domain catch-
all), it now auto-enables Override and pre-fills the alias. Quick reply
honors the same resolution. The setting is relabeled to reflect the
broader behavior.
JMAP: client.sendEmail gains an optional envelopeMailFrom; when set, the
EmailSubmission includes an explicit envelope with that mailFrom and the
to/cc/bcc as rcptTo so header-From and envelope can diverge (JMAP §7.3).
S/MIME: override is incompatible with sign/encrypt and is refused with a
clear error — signing a different visible From from the identity's
certificate Subject would produce messages clients reject.
Tests: resolveReplyFrom covers exact match, sub-address stripping,
catch-all detection, identity preference, and foreign-domain null.
