Original Pull Request: https://github.com/anomalyco/opencode/pull/12877

State: open
Merged: No

Summary

  • Add global signal handlers (SIGTERM, SIGINT, SIGHUP) for graceful shutdown
  • Calls Instance.disposeAll() to clean up LSP servers, MCP clients, PTY sessions, workers
  • Uses 5-second timeout before force exit
  • Uses standard Unix exit codes (128 + signal number)

Fixes

  • Fixes #11527 - OpenCode leaves an orphaned process when killed
  • Fixes #12767 - Missing SIGHUP handler causes orphaned process accumulation
  • Fixes #10563 - Orphaned processes when terminal closes without explicit exit
