Linus Rath b86e0a118e fix: size provider batches by what the Binder transaction carries #34
The batch budget counted JSON characters, but a Parcel carries strings
as UTF-16 plus a few hundred bytes per operation, so a full batch was
about 700 KB of a 1 MB Binder buffer the whole process shares. Batches
are now weighed at two bytes per character plus 300 bytes per op and
kept under 500 KB of that. The state op no longer joins a batch whose
last item already fills a provider yield window of 499 operations,
which ContactsProvider refused.

Bulwark Webmail

Bulwark Mobile

Beta - work in progress. Many features are unfinished or rough. Expect bugs, missing functionality, and breaking changes between releases. Do not rely on this for primary email yet.

React Native (Expo SDK 54) client for Bulwark Webmail - a JMAP-based mail, calendar, and contacts app.

What works today

  • Sign in to any JMAP server (e.g. Stalwart)
  • Multiple accounts
  • Email list, threads, compose
  • Calendar (basic)
  • Contacts (basic)
  • Push notifications via the Bulwark relay - FCM by default, or UnifiedPush (e.g. ntfy) for devices without Google Play services
  • In-app sideload updates from GitHub Releases

What's missing or rough

  • iOS builds, but push notifications and client certificates are Android-only so far
  • S/MIME, plugins, themes - UI stubs only (filters & rules, the vacation responder and file storage are real implementations)
  • Calendar editing is partial; contacts editing is basic
  • No Play Store distribution yet (sideload APK from Releases); iOS ships via TestFlight

Run locally

npm install
npx expo start

Then press a for Android, i for iOS, or scan the QR with Expo Go.

For release APK builds and signing see docs/android-release.md. For iOS builds and TestFlight distribution see docs/ios-release.md.
