The sandbox runtime copied only the three policy flags from the host's
features, so a flag an assistant area adds (sidePanel, files, ...) never
reached api.host.features and the plugin hid the feature. The runtime
now copies every other flag the host names as true or false.
The host bridge assertions compare against withAssistant(...) like the
snapshot ones already did, because the init payload and host-change
carry the assistant's flags on top of the three policy flags.
The assistant's new host calls come in four areas (context, actions,
Files, the panel in every view), built side by side. Each area gets its
own files under lib/plugin-sandbox/assistant for its permissions, method
table, dispatcher, host feature flags and sandbox methods; the shared
files only read the merged result. No area adds anything yet. The host
features test now compares against the core flags plus the areas' flags.
The review of offline mode found ways to send a message twice, to lose
unsent mail without a word, and to send mail without its signing,
encryption or check plugin. This fixes them and the smaller findings:
- each outbox message is taken for sending in one database transaction
under a Web Lock per account; only a failure before the submission
request (SendNotStartedError from the client) puts it back, any other
one marks it "may have gone out"; read-backs after the submission no
longer fail a send; a send of a closed tab turns uncertain after a minute
- every sign-out the user didn't confirm names the deleted messages on
the sign-in page, or in a toast when another account stays signed in
- nothing is queued while an enabled plugin isn't running (after a start
without the network none can); the composer says why
- the outbox waits for a fresh policy and holds messages the rules have
since made stricter (a required label, a required send check)
- another tab switching offline mode off sticks: only switching it on
may create the database
- only attachments of kept messages are kept, filed with their message,
deleted with it and under the cap between syncs; file names and types
are sealed; folders that went away leave the scope, and a folder that
couldn't be asked keeps its mail without holding the others back
- a group scope that forbids offline mode waits until the account's
groups are known; one server down no longer holds another's mail
- an offline start only when the server is really unreachable, and the
real sign-in follows by itself once it answers
- the service worker files pages and chunks under the build that served
them, and the shell list of another build isn't kept under this one
- a raw send counts as the composer's only from the plugin running its
takeover, for that identity
- errors and refusals are in all languages; the banner tells "offline"
from "server can't be reached"; outbox buttons name their message;
changes and messages go in the order they were made
The out-of-office calendar block (package B) syncs from the vacation store, so the plugin vacation API now reaches client.getAccountId and supportsCalendars. The real client has both; the test's mock client didn't, so two cases threw. The mock gains them; no assertion changed.
