Signal handlers covered SIGINT/SIGTERM/SIGBREAK/beforeExit/exit, but a
synchronous throw or a top-level rejected promise terminated the process
without letting TmuxSessionManager (or any other registered manager) run
its shutdown hook. That reliably left orphan tmux panes after an opencode
crash.
Added registration for uncaughtException and unhandledRejection that fan
out through the existing cleanupAll() path, set process.exitCode = 1,
and arm the same 6 second forced-exit guard we use for signals. Test
helpers hold process-level spies so the new tests do not leak listeners
between runs.
Two issues fixed:
1. process-cleanup.ts used fire-and-forget void Promise for shutdown
handlers — now properly collects and awaits all cleanup promises
via Promise.allSettled, with dedup guard to prevent double cleanup
2. TmuxSessionManager was never registered for process cleanup —
now registered in create-managers.ts via registerManagerForCleanup
Also fixed setTimeout().unref() which could let the process exit
before cleanup completes.
- Revert getMessageDir to original join(MESSAGE_STORAGE, sessionID) behavior
- Fix dead subagentSessions.delete by capturing previousSessionID before tryFallbackRetry
- Add .unref() to process cleanup setTimeout to prevent 6s hang on Ctrl-C
- Add missing isUnstableAgent to fallback retry input mapping
- Fix process-cleanup tests to use exit listener instead of SIGINT at index 0
- Swap test filenames in compaction-aware-message-resolver to exercise skip logic correctly
