- MCP teardown race: add shutdownGeneration counter to prevent
in-flight connections from resurrecting after disconnectAll
- MCP multi-key disconnect race: replace disconnectedSessions Set
with generation-based Map to track per-session disconnect events
- MCP clients: check shutdownGeneration in stdio/http client
creators before inserting into state.clients
- BackgroundManager: call clearTaskHistoryWhenParentTasksGone after
timer-based task removal in scheduleTaskRemoval and notifyParentSession
- BackgroundManager: clean completedTaskSummaries when parent has
no remaining tasks
- Plugin dispose: remove duplicate tmuxSessionManager.cleanup call
since BackgroundManager.shutdown already handles it via onShutdown
Test expected timers only after allComplete, but H2 fix intentionally
decoupled per-task cleanup from sibling completion state. Updated
assertion to expect timer after individual task notification.
Plugin created managers, hooks, intervals, and process listeners on
every load but had no teardown mechanism. On plugin reload, old
instances remained alive causing cumulative memory leaks.
- Add createPluginDispose() orchestrating shutdown sequence:
backgroundManager.shutdown() → skillMcpManager.disconnectAll() →
disposeHooks()
- Add disposeHooks() aggregator with safe optional chaining
- Wire dispose into index.ts to clean previous instance on reload
- Make dispose idempotent (safe to call multiple times)
Tests: 4 pass, 8 expects
H3: cancelTask(skipNotification=true) now schedules task removal.
Previously the early return path skipped cleanup, leaking task objects
in this.tasks Map permanently. Extracted scheduleTaskRemoval() helper
called from both skipNotification and normal paths.
H2: Per-task completion cleanup timer decoupled from allComplete check.
Previously cleanup timer only ran when ALL sibling tasks completed. Now
each finished task gets its own removal timer regardless of siblings.
H1+C2: TaskHistory.clearAll() added and wired into shutdown(). Added
clearSession() calls on session error/deletion and prune cycles.
taskHistory was the only data structure missed by shutdown().
Tests: 10 pass (3 cancel + 3 completion + 4 history)
H7: Process 'exit'/'SIGINT' listeners registered per-session were
never removed when all sessions disconnected, accumulating handlers.
- Add unregisterProcessCleanup() called in disconnectAll()
H8: Race condition where disconnectSession() during pending connection
left orphan clients in state.clients.
- Add disconnectedSessions Set to track mid-flight disconnects
- Check disconnect marker after connection resolves, close if stale
- Clear marker on reconnection for same session
Tests: 6 pass (3 disconnect + 3 race)
When queryWindowState returned null during session deletion, the
session mapping was deleted but the real tmux pane stayed alive,
creating zombie panes.
- Add closePending/closeRetryCount fields to TrackedSession
- Mark sessions closePending instead of deleting on close failure
- Add retryPendingCloses() called from onSessionCreated and cleanup
- Force-remove mappings after 3 failed retry attempts
- Extract TrackedSessionState helper for field initialization
Tests: 3 pass, 9 expects
Prune interval created inside hook was not exposed for disposal,
preventing cleanup on plugin unload.
- Add dispose() method that clears the prune interval
- Export dispose in hook return type
Tests: 2 pass, 6 expects
setInterval for model availability monitoring was never cleared,
keeping the hook alive indefinitely with no dispose mechanism.
- Add dispose() method to RuntimeFallbackHook that clears interval
- Track intervalId in hook state for cleanup
- Export dispose in hook return type
Tests: 3 pass, 10 expects
Sync call_omo_agent leaked entries in global activeSessionMessages
and activeSessionToolResults Sets when execution threw errors,
since cleanup only ran on success path.
- Wrap session Set operations in try/finally blocks
- Ensure Set.delete() runs regardless of success/failure
- Add guard against double-cleanup
Tests: 2 pass, 14 expects
processedCommands and recentResults Sets grew infinitely because
Date.now() in dedup keys made deduplication impossible and no
session.deleted cleanup existed.
- Extract ProcessedCommandStore with maxSize cap and TTL-based eviction
- Add session cleanup on session.deleted event
- Remove Date.now() from dedup keys for effective deduplication
- Add dispose() for interval cleanup
Tests: 3 pass, 9 expects
