fix(client): contain previews and recover offline sessions and calls - #229
Merged
Merged
Conversation
Avoid retrying a deletion already accepted remotely when local persistence fails. Carry pause and seek through web audio decode, and detect extensionless photos from their bytes. Refs oxidezap#200
Keep media previews modal across call controls, retry the existing WhatsApp session over IPC v40, and reject stale calls after reconnect. Preserve local history and connection state while offline.
📝 WalkthroughWalkthroughThe PR adds an IPC request for WhatsApp reconnection and updates connection-aware call handling. It also changes modal hit testing, pending audio controls, extensionless image detection, and local handling of remote-delete results. ChangesWhatsApp reconnection and call lifecycle
Modal and call-card interactions
Pending audio controls
Media picker MIME detection

Move ReconnectSession into begin_slow.
Bridge::execute is awaited inside the bridge loop’s select!. The reconnect arm awaits client.retry_connection(), which awaits client.pause() and its teardown operations. While those operations are pending, the loop cannot handle another command or consume session events or video frames. The four-frame video channel can overflow.
Keep the logged-out refusal and outcome mapping. Hold an in-flight permit until the retry completes.

Summary
Keep media and attachment previews modal, recover the existing WhatsApp session when connectivity returns, and prevent stale calls from ringing after reconnect. Also complete the three CodeRabbit follow-ups from #200: pending WebAudio controls, extensionless photo detection, and deletion results after remote success.
PR #200 is already merged as
d414f89. This is a follow-up based directly on that merged commit, containing only142c2a9and4073ec3. At publication, it is zero commits behindorigin/main, and a merge-tree check completes without conflicts.Problems, causes, and fixes
1. Clicks through the fullscreen media viewer
2. Clicks through the paste/attachment confirmation preview
3. Call cards rendered above modal surfaces
4. WhatsApp disconnection treated as front-end attachment failure
DisconnectedUI event used the generic connection-ended path, and the session control feed did not explicitly subscribe to WhatsApp disconnection events.Disconnected, keep cached conversations readable inAppState::Offline, stop transient recording/playback controls, and retire call cards on transport loss. Preserve the existing daemon connection, session identity, and history store while the library's existing supervisor performs automatic reconnect with its existing backoff. Only a realConnectedevent restores sending.5. Manual Retry did not wake the existing WhatsApp reconnect supervisor
ReconnectSessionover IPC protocol v40, route it through the daemon to the live session, and use the existing client'spause/resumelifecycle to wake its supervisor. Render the offline strip wherever the selected conversation is not already showing it. This reuses the same session and store, preserves history, and does not construct a second bot or session writer. A late click on an already connected session is a no-op. A daemon refusal reports its reason and stays offline; only loss of IPC starts attachment recovery. Logged-out accounts must pair again. A successful request means retry was accepted, not that WhatsApp is connected. Older daemon/front-end protocol pairs are rejected rather than attempting this unknown request.6. Old calls reappeared after reconnect
IncomingCall; this is a conservative freshness policy allowing delivery delay and modest clock skew, not a claimed server TTL, and future timestamps remain accepted. Clear call state in disconnected snapshots and when the GUI is offline, and make repeated call IDs idempotent in ringing/active/waiting state.7. CodeRabbit follow-up: pause and seek during pending WebAudio decode
8. CodeRabbit follow-up: extensionless photos rejected by Photos & Videos
application/octet-streamdespite recognizable image bytes.9. CodeRabbit follow-up: deletion reported failure after remote success
Validation
All of the following passed on macOS for this branch:
cargo fmt --all -- --check cargo clippy --locked --offline --workspace --all-targets --all-features -- -D warnings cargo test --locked --offline --workspace --all-features --quietClippy and tests used the existing shared Cargo target directory with
CARGO_INCREMENTAL=0; the test run had access to the Unix sockets required by the daemon/IPC integration tests.Regression coverage includes real GPUI clicks at a previously verified call-control position under both previews, preservation of call state and restoration of keyboard ownership, offline history retention, rejected retry behavior, IPC v40 round-tripping and compatibility rejection, stale offers across reconnect and caller lookup, offline snapshots, duplicate call IDs, pending audio controls, extensionless picker images, and remote/local deletion ordering and failures.
docs/gotchas.mdrecords the reconnect and call-freshness constraints.Manual testing to date is macOS-only for the preceding work. The new fixes in this follow-up have not yet been exercised manually. No manual validation on Linux, Windows, or the web is claimed. The checks above are macOS host checks; they do not claim a wasm build or browser test run. CodeRabbit reviewed #200 and its three follow-ups are included here; this new PR has not yet received a CodeRabbit review.
Summary by cubic
Keeps media and attachment previews from activating call controls behind them, and recovers the existing WhatsApp session (not the whole client) when connectivity returns while preventing stale calls from ringing again. Also includes pending-audio playback controls, extensionless photo detection, and correct deletion reporting after remote success.
Connection and call recovery
Disconnectedevent now means offline: cached history stays readable, transient recording/playback controls stop, and call cards are retired; only a realConnectedevent restores sending.ReconnectSessionIPC request (protocol v40) addressed to the live session, waking its reconnect supervisor viapause/resume; a late click on an already connected session is a no-op, and a daemon refusal stays offline with its reason (only losing IPC starts front-end recovery).Picker, playback, and deletion follow-ups
Written for commit 4073ec3. Summary will update on new commits.
