Every reader now stops at the read's character budget, a cell at 4,000
characters, one Office XML part at 12 MB, and parts with a DTD are
refused. A compound file named .docx is encrypted only when it holds an
EncryptedPackage stream, else unsupported; .eml files are unsupported
instead of raw MIME; maxChars that isn't a number falls back to 20,000.
attachment-text.test.ts: the zip bomb test passes the cap as an option
now, and a bare compound file named secret.docx is expected unsupported
(it is a legacy file under a new name; limits.test.ts covers the
password-protected one).
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.
EmailReadView.attachments gain cid and alt for images the HTML shows
inline. plugin-projection.test.ts now expects the cid on its inline
logo, since the view carries it.
api.email.getAttachmentText reads PDF (pdf.js), Word, Excel, PowerPoint
and OpenDocument files (own reader over fflate and DOMParser, unpacking
capped at 50 MB), text, CSV, HTML, calendar and address files, and
answers with a status for what it can't read. The extraction lives in
lib/attachment-text so Files can use it too.
The sandbox runtime now copies every flag the host sends into
api.host.features; before, it kept only the three core flags, so the
assistant's flags never reached a plugin. The host bridge assertions in
plugin-host-features.test.ts compare against the core flags plus the
assistant's (withAssistant), since the init payload and host-change now
carry attachmentText too.
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.
Settings > Backup & reset gets "Keep mail on this device", off until the
user turns it on in this browser. While it is on:
- the JMAP client hands the server's answers to an encrypted cache in
IndexedDB (AES-GCM, non-extractable key) and answers from it when the
network is gone: the folder list, the last 30 days of the Inbox and of
the folders the user opened, bodies and attachments, at most 250 MB,
oldest out first; a background sync keeps it current
- read, flag, tags and moves made offline are queued and sent in order
when the server answers again; deleting for good and emptying a folder
are refused offline
- the composer, quick reply and the S/MIME and PGP plugins' sends that
complete the composer's go to an outbox once every step up to the
transport ran (checks, label, signature, plugin send checks); only the
finished send waits, with files attached offline
- the service worker keeps this build's app shell, so the app also
starts offline from the kept session and the last policy
- a full sign-out, the idle sign-out and signing one account out delete
it, a sign-out the user starts asks first when mail is unsent, and the
login page names what an automatic sign-out deleted; a policy fetch
that forbids it (devices.noOffline) wipes that account
Not in Lite.
