Bulwark had no read-receipt support (JMAP/Stalwart have no native MDN).
End-to-end, client-side, in three parts:
- Request (compose): a toolbar toggle (MailCheck, green when on) sets
Disposition-Notification-To on the outgoing message via the JMAP
"header:<name>:asText" create property. Threaded composer -> page ->
email-store -> client.sendEmail. Default from requestReadReceiptDefault.
- Detect (viewer): reads Disposition-Notification-To case-insensitively from
the parsed headers and shows a banner (green Send / red Ignore) in the
unified notification bar. Hidden in Sent/Drafts/Trash/Junk and once handled.
message/disposition-notification + message/delivery-status report parts are
filtered out of the attachment list.
- Respond (MDN): lib/mdn.ts builds an RFC 8098 multipart/report (text/plain +
message/disposition-notification, UTF-8/base64, localized subject + body).
client.sendReadReceipt uploads the blob, imports it into Sent via
Email/import, then submits with an explicit envelope. Both Send and Ignore
set the $MDNSent keyword (RFC 3503) so no client re-prompts. Behaviour
configurable: ask / always / never.
New: lib/mdn.ts, read-receipt-banner.tsx. Settings (requestReadReceiptDefault,
readReceiptResponse) + UI. All 17 locales.
The plugin runtime received the active locale (init payload + 'locale-change')
and plugins could declare a `locales` map, but none of it was usable: the
locales never reached the runtime, and buildPluginApi exposed no i18n. So
plugin code calling pluginApi.i18n.t(...) (as the External Link Warning plugin
does) always got undefined and fell back to English.
Thread plugin locales end to end and surface an i18n API:
- ServerPlugin gains `locales`; the upload route persists manifest.locales
(alongside configSchema/settingsSchema), and /api/plugins surfaces it to the
client so it flows registry -> client -> sandbox host-bridge -> runtime.
- runtime sets __PLUGIN_LOCALE__ at init (not only on later 'locale-change')
and buildPluginApi exposes `i18n.locale` + `i18n.t(key, vars)` resolving
against the plugin's declared locales (manifest.locales) with English/key
fallback and {placeholder} interpolation.
Lets any sandboxed plugin localize its strings from its manifest.
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%).
