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 implemented a significant improvement to the Synchronizer actor's lifecycle management. Previously, its existence was tied to manual acquire and release calls. Now, the Synchronizer will automatically detect when its dependent modules, such as the Trainer and Explorer, are no longer active and will gracefully terminate itself. This change streamlines resource management and reduces the potential for orphaned actors.
Highlights
- Automatic Synchronizer Lifecycle: The Synchronizer actor now automatically terminates when all associated Trainer and Explorer modules are no longer running, replacing the previous manual reference counting mechanism.
- Synchronizer Module Tracking: The Synchronizer's constructor now accepts a reference to the module that creates it, and it continuously monitors the liveness of all registered modules to determine when to exit.
- Simplified Module Shutdown: Manual acquire and release calls for the Synchronizer have been removed from Trainer and Explorer classes, simplifying their shutdown procedures.
- New Liveness Checks: Trainer and Explorer classes now include an is_alive method, which the Synchronizer uses to check their operational status.
- New Test Coverage: A new test case, TestSynchronizerExit, has been added to validate the correct automatic termination behavior of the Synchronizer.

Code Review
This pull request introduces an automatic lifecycle management for the Synchronizer actor by tracking its client modules and exiting when all of them have terminated. This is a solid improvement over the previous manual reference counting system. My review includes suggestions to enhance the robustness and clarity of the implementation, such as using a set to track modules and employing more specific exception handling. Additionally, I've pointed out a potential flakiness issue in the new test case and suggested a way to make it more reliable.
