Mobile QoL: remote project add, auto-refresh, and daemon-restart recovery by Crabbotix · Pull Request #455 · Dimillian/CodexMonitor

Crabbotix · 2026-02-19T07:42:10Z

What

Add support for adding Projects from mobile while connected to a remote server (manual path entry fallback in remote+iPhone flow).
Improve automatic refresh behavior for remote usage:
- workspace refresh polling now responds correctly to backend mode/visibility lifecycle.
- thread live connection recovery is stronger after interruptions.
Add reconnect hardening for daemon restarts:
- stale live stream watchdog with auto-reconnect.
- reconnect on detached events when visible/focused.
- improved reconnect sequencing and cleanup handling.
Add server-side busy indication in the sidebar for workspaces with active processing/streaming thread activity.
Add regression tests for the new remote refresh/reconnect behaviors and mobile add-project flow.

Why

iPhone users connected to a remote Codex Monitor server currently hit friction when adding projects and when daemon/live-stream state changes.
After daemon restarts, the app could get stuck until manual restart; this patch improves self-healing reconnect behavior.
Workspace-level activity visibility helps users quickly see active/streaming work without drilling into each thread.

How

Frontend hooks:
- updated useWorkspaces to support remote mobile manual path entry.
- updated useWorkspaceRefreshOnFocus to properly rebind polling lifecycle by mode/interval/visibility.
- updated useRemoteThreadLiveConnection with stale-live detection, focus-aware reconnect triggers, and reconnect sequence hardening.
UI:
- sidebar computes workspace processing activity and renders a colored indicator in workspace rows.
Tests:
- added/expanded tests for reconnect races, stale recovery, focus/visibility polling behavior, and mobile remote add-project flow.

Testing status

Untested manually on device right now (I can only run end-to-end/manual verification this evening).

src/features/app/hooks/useRemoteThreadLiveConnection.ts

+      if (connectionStateRef.current === "live") {
+        lastThreadEventAtRef.current = Date.now();


Mark stream live on activity events

Gating lastThreadEventAt updates behind connectionStateRef.current === "live" means the hook now relies on thread/live_heartbeat to ever enter/maintain live mode, but the in-repo backends currently emit attach/detach only (see src-tauri/src/codex/mod.rs and src-tauri/src/bin/codex_monitor_daemon.rs thread/live_attached/thread/live_detached paths) and no heartbeat producer. In that environment the state can stay stuck in polling, so the stale watchdog (connectionStateRef.current === "live") never triggers after daemon interruptions and live-recovery logic is effectively bypassed.

Useful? React with 👍 / 👎.

Addressed in 2f35d4b.

What changed:

In useRemoteThreadLiveConnection, thread activity events (item/*, turn/*, error, thread/tokenUsage/updated) now update lastThreadEventAtRef and set connection state to "live".

Added regression test: promotes polling state to live on thread activity without heartbeat.

Addressed a follow-up reconnect-churn risk from RepoPrompt review in commit 274d092.

Change summary:

useRemoteThreadLiveConnection reconnect trigger now keys off stable workspace primitives (workspace id and connected) instead of full workspace object identity.
Added a guard to skip redundant reconnect when already subscribed and not disconnected.
Added regression test covering rerender with a new workspace object (same key) to ensure no extra subscribe/unsubscribe.

src/features/app/hooks/useRemoteThreadLiveConnection.ts

+          if (isDocumentVisible() && isWindowFocused()) {
+            void reconnectLive(activeWorkspaceId, selectedThreadId, {
+              runResume: true,


Ignore self-triggered detach events before reconnecting

This unconditional reconnect on thread/live_detached fires even when the detach was initiated locally by reconnectLive itself (the dedupe path now calls threadLiveUnsubscribe before re-subscribing for the same key). In a visible/focused window, that unsubscribe emits thread/live_detached, which re-enters reconnectLive and creates overlapping reconnect sequences for the same thread, causing redundant resume/subscribe calls and racey state transitions instead of a single reconnect attempt.

Useful? React with 👍 / 👎.

Addressed in commit 16ee857.

Fixes:

Added a self-detach ignore guard for the key currently being dedupe-unsubscribed, so a locally triggered thread/live_detached event does not recursively re-enter reconnect.

Added in-flight same-key reconnect coalescing to avoid concurrent duplicate subscribe/resume attempts.

Added regression tests for both behaviors.

src/features/app/hooks/useRemoteThreadLiveConnection.ts

+      const staleLive =
+        connectionStateRef.current === "live" &&
+        lastEventAt > 0 &&
+        now - lastEventAt >= REMOTE_LIVE_STALE_TIMEOUT_MS;


Skip stale-live recovery when thread is idle

This stale check assumes that no events for REMOTE_LIVE_STALE_TIMEOUT_MS means a broken connection, but it never gates on activeThreadIsProcessing; as a result, once a normal item/* or turn/* event marks the connection live, an idle thread will be treated as stale after 20s and trigger a false “Server connection interrupted” toast plus reconnect. I checked the backend emitters in src-tauri/src/codex/mod.rs and src-tauri/src/bin/codex_monitor_daemon.rs, and they emit attach/detach plus thread activity, not a guaranteed heartbeat cadence for idle periods, so this branch can fire during healthy idle sessions.

Never again PR like that with a bit of everything. ok? Overall, there is stuff I like, but I'm fixing some other things that I don't like and that are downgrading.

Dimillian · 2026-02-20T08:57:29Z

Overall best thing is that it can finally reconnect polling thread to live and that's so good!
