Bug 1a - RuntimeError when _registry_guard is None:
- Added explicit check for _registry_guard initialization
- Now raises clear RuntimeError instead of cryptic TypeError
- Helps users understand they need to call initialize_share_data() first
Bug 1b - Workspace async_locks not visible across processes:
- Created new _workspace_async_locks dict for per-process storage
- Fixed issue where async_locks modifications in one process were invisible to others
- This is correct design since asyncio.Lock objects cannot be pickled/shared
Why per-process async_locks:
- asyncio.Lock objects cannot be shared across processes
- Each process needs its own asyncio.Lock instances for coroutine sync
- Cross-process sync is handled by Manager.RLock() in _sync_locks
- Within-process async sync is handled by per-process asyncio.Lock
Testing:
- All 17 existing workspace lock tests pass
- Added 3 new tests specifically for bug verification
- Total 20 tests passing
Impact:
- Fixes potential race conditions in multiprocess scenarios
- Ensures proper synchronization both across and within processes
- Maintains backward compatibility
