Summary of Changes
Hello @chenyushuo, I'm Gemini Code Assist1! I'm currently reviewing this pull request and will post my feedback shortly. In the meantime, here's a summary to help you and other reviewers quickly get up to speed!
I've addressed a bug in the Synchronizer class related to concurrency and asynchronous operations. My changes primarily focus on ensuring thread safety for shared state, converting synchronous methods to asynchronous ones where appropriate, and updating their call sites to correctly await their execution. This improves the robustness and responsiveness of the Synchronizer's module tracking and status update mechanisms.
Highlights
- Concurrency Control: I've implemented an
asyncio.Lockto ensure thread-safe operations on the_modulesset, preventing potential race conditions when modules are added or checked. - Asynchronous Method Conversion: I've converted key methods like
add_moduleandset_explorer_status, along with the nestedsync_failedfunction, to be asynchronous. This ensures properawaiting of these operations and aligns with theasyncioframework. - Await Call Updates: I've updated all call sites for the newly asynchronous
set_explorer_statusandsync_failedfunctions to correctlyawaittheir execution. - Performance Optimization: I've optimized the
_check_modulesloop by reducing the sleep interval from 5 seconds to 1 second, which should make the module checking more responsive. - Ray Actor Interaction Correction: I've adjusted the
get_actormethod to remove theray.getcall foradd_module, asadd_moduleis now anasyncmethod and doesn't require blocking retrieval of its remote execution result.

Code Review
This pull request primarily refactors the Synchronizer by moving it into a manager package, which is a good organizational improvement. The changes also address a bug in the Synchronizer's lifecycle management by introducing a lock for concurrent access to its tracked modules and improve exception handling for async iterators by correctly using StopAsyncIteration.
My review highlights a few areas for improvement:
- Test Robustness: A polling loop in a test should have a timeout to prevent it from hanging.
- Concurrency: A minor race condition in the
Synchronizer'sadd_modulemethod should be addressed. - Code Clarity: A leftover debug string in a docstring should be removed.
Overall, these are solid changes that enhance the codebase's structure and robustness. Addressing the feedback will further improve the quality of the code.
