Plugins running in iframe sandboxes previously lacked access to the user's regional formatting settings (dateLocale, timeFormat 12h/24h, timeZone, and firstDayOfWeek) unless they requested privileged settings:read permissions.
This mirrors the host's resolved presentation preferences into the plugin sandbox:
- Adds RegionalSnapshot (locale, dateLocale, hour12, timeZone, firstDayOfWeek) to BackgroundInit, SlotInit, and LocaleChangeMsg.
- Implements snapshotRegionalSettings() in host-bridge, reusing host resolveDateLocale() and getEffectiveTimeZone().
- Subscribes stores/plugin-store.ts to useSettingsStore to broadcast updates to running sandboxes when regional preferences change.
- Exposes api.i18n.formatTime(date, options) and api.i18n.formatDate(date, options) along with regional getters on api.i18n.
The admin page offered "User Plugin Uploads" and "Require Admin
Approval", but nothing in Settings used them: there was no upload, no
uninstall and no way to ask for approval, and the admin had no list of
requests. The approval code that existed pinned a hash of the code only
and showed the admin a manifest the browser sent, never the code.
Now:
- Settings > Plugins has an install button (when uploads are allowed),
a remove button for the user's own plugins, and lists in plain
language what each plugin may do, high-risk items first
- an install sends the ZIP to the server, which reads the manifest and
code itself and pins the request to a hash of both
- the admin Plugins tab lists requests with the code and approves or
denies them; a user may have 10 open requests
- a user plugin is checked again on every start, so a revoked approval
or turning user plugins off takes effect
- the consent dialog and the plugin settings are translated, use the
theme colours, and show the sites a plugin may send data to
The Settings upload, the admin upload, the marketplace install and the
marketplace preview each parsed the ZIP and manifest with their own copy
of the code, and the copies had drifted. A `permissions` string skipped
validation and was then matched by substring, a small ZIP could inflate
to hundreds of megabytes on the server, the Settings upload dropped
`locales` and took origin lists unchecked, and settings schemas were
never checked at all.
All of them now go through `lib/extension-package.ts`:
- every file is inflated through a byte cap, with a limit on entries
- one manifest check: types, permissions, entrypoint, version,
minAppVersion, settingsSchema, configSchema, locales and origin lists
- only checked fields are stored
