Review of the pop-out work found ways to lose text, a wrong sign-out and
changes reaching ordinary browser tabs.
- Drafts: a closing window hands text over only to a main window holding
its login, and asks instead when the last save failed, the browser is
offline, a save is running or plugins could still have a say. A failed
rescue goes to "Continue draft". The opening window lets go only once
the composer is on screen, also for Edit draft in a message window.
Send options travel with the draft. Closing during a send asks first.
- Sessions: answers are encrypted for the window that asked, and only a
window holding the login answers. A renewal queued on the lock can be
called off by a sign-out, signs nobody out once its account is gone, and
takes the cached token after waiting (Rauthy `nbf`, #552).
- Ordinary tabs run none of the host. No lock is held for life.
- A message window hides after a refused session and waits for its
folders; a composer stays on screen with its text. Another tab dropping a
login it couldn't restore no longer closes pop-outs.
- Plain-text mail stays selectable in the desktop app. Folder save renames
reserved and shell names and skips one refused name. All display-mode
checks know the overlay. The attachment bar keeps to one row.
The earlier test that accepted text being gone after a failed rescue now
asserts that it reaches the "Continue draft" slot.
Any site could POST a form to the share target on load: with no clicks
the composer opened with its subject and file, and autosave stored a
real draft on the server 2 seconds later. The worker can't see where a
POST came from, and Chromium's link capturing accepts form submissions,
so an installed-app window proves nothing either.
- every share landing now asks first, in every window and browser; a
text landing address gets the same question. Nothing goes up before
the answer.
- handed-in text and files are the composer's starting state: no
autosave, page-close save or sign-out flush before the first real
edit.
- the worker ignores frames, keeps at most 5 entries and 100 MB for 15
minutes, sweeps on activate, on each share and from a page timer,
and seals what it keeps with a key passed in the landing fragment.
Offline wipes clear it too.
- the server fallback uses the fragment and caps by encoded length:
3000 Japanese characters made a 27 KB `Location` and a 431.
- a second compose handoff waits until the composer closes, also one
set aside by reading a message, where it used to replace the first.
- a launch leaving the mail page saves what was just typed first.
- an expired handoff or a missing stored file now says so; shares get
the control-character stripping and limits of `parseMailto`.
Existing tests changed because the landing moved from the query to the
fragment, stored entries gained a sealed part, and a share now asks
first.
An installed app had no title bar of its own, no way to save attachments
except a zip, and "pop out" stayed inside the page. A new window was a
second copy of the app that had to restore the session itself, and on
start-up that evicts any login made without "Remember me" from the list
every window shares.
- Title bar: `display_override` with `window-controls-overlay`, one
`--titlebar-inset` variable at the page roots and skeletons, and a drag
strip with the window title. 0 without an overlay, so nothing moves.
- Save all to a folder: `showDirectoryPicker`, asking the device policy
before the picker and before each file, with the zip as the fallback.
- Pop-out routes `/popout/message/<id>` and `/popout/compose`, on offer in
an installed app or when the desktop bridge has windows. Hidden in Lite.
- A pop-out borrows the main window's session and never evicts or starts a
token timer. Every renewal now takes a Web Lock, so two windows can't
send the same refresh token, which Stalwart 1.0 may treat as a replay.
- A draft moves to its window under the same id. A closing window hands
unsaved text to the main window to save, since its own request wouldn't
survive the close.
- Read state, drafts, theme and language follow across windows, and
`html[data-desktop]` gates the app-like behaviour in `app/desktop.css`.
Review of the notification actions. With a plugin that may stop a move
or read change, or a silent tab holding the login, the message now
opens instead of the route acting. The route answers 401 under a
session limit, and neither path touches a message since moved to Trash
or Junk. A tab that thawed declines an old click, Archive follows the
gate of the notification's login and files into a shared-out Archive
as the app's button does, Reply opens a composer in the Pro shell, the
route retries once when another client made the folder first and
leaves no empty folder behind, and logins match however the server
address is written.
Two assertions of this feature's own tests change: the route answers
401, not 403, when a login's scopes can't be worked out, since that now
also covers session limits; a tab's message to the page now carries
`at`.
The Pro shell's mail surface now reads a parked link's query from the
handoff: the address bar may have none by its first render, which lost
`?slot=` and `?owner=` there too.
A notification for one message gets buttons where the browser has room
for them, and a click on its body works as before. The service worker
has no login, so an open tab takes the action first, through the store
actions. With no tab open a new same-origin route, /api/push/action,
does Mark read and Archive with the context cookie. When the cookie is
gone, the token has expired or the login can't be told apart, the
message opens in the app instead. Reply opens the composer through a
`?reply=1` link, with any text typed on the notification.
- `public/sw.js`: buttons, asking open tabs, the route, `sync` handling
- `app/api/push/action`: same-origin, checks the login and the account,
honours the admin's Archive gate, files by the mirrored archive mode
- `lib/pwa-notify`: the page's side, the mirror for the worker, and
`requestOutboxSync`, which the offline queue calls
- Background Sync, thin version: a `sync` event tells open tabs to flush
Two push-preview-route assertions change: they match the whole answer
for a named message, which now also carries `login`, what the action
route checks so a stale notification can't act on whoever holds the
cookie slot now.
Thunderbird's envelope line is when a message was copied into the folder, so a migrated folder showed years of mail on one day. The envelope date now counts only on Bulwark's own export lines and on lines with a time zone. The mbox writer tests now expect the export's own envelope sender, bulwark-export, in place of MAILER-DAEMON, which marks those lines.
