fix(runtime): harden JSONL async I/O and DB put_batch thread validation ( #3084 )
...
* fix(runtime): harden JSONL async I/O and DB put_batch thread validation (#2816 )
- JsonlRunEventStore: offload all file I/O to asyncio.to_thread() so the
event loop is never blocked; add per-thread asyncio.Lock to serialise
concurrent puts and prevent interleaved JSONL lines
- Split _ensure_seq_loaded into a sync _compute_max_seq (runs in thread)
and an async wrapper; seq counter is recovered from disk on fresh store init
- DbRunEventStore.put_batch: raise ValueError when events span multiple
thread_ids (previously silently assumed same thread)
- Add test_jsonl_event_store_async_io.py: 12 tests covering lock reuse,
concurrent seq monotonicity, disk recovery, and mixed-thread batch rejection

* fix: address Copilot review comments
- delete_by_thread: pop _write_locks after releasing the lock to prevent
unbounded growth when threads are repeatedly created and deleted
- tests: add regression guard asserting asyncio.to_thread is called for
_write_record in put(); assert _write_locks entry removed on delete
* fix(lint): move patch import to local scope to fix ruff I001
* fix(lint): apply ruff check+format fixes to test file
* fix(runtime): address review feedback for JSONL async I/O hardening (#2816 )
Use setdefault for atomic lock init in _get_write_lock; pop _write_locks
inside the held lock scope in delete_by_thread; update test docstring
and assert lock entry also cleared on delete.
