Summary of Changes
Hello @MervinPraison, 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!
This pull request implements a crucial fix to enhance the stability of the application during shutdown. By modifying the telemetry's exit handling, it ensures that all associated aiohttp sessions are gracefully closed, thereby resolving a specific ImportError that previously occurred due to resource mismanagement during Python interpreter termination.
Highlights
- Telemetry Shutdown Fix: I've updated the
atexithandler for telemetry to callshutdown()instead offlush(). This ensures thataiohttpsessions used by the PostHog client are properly closed during application exit. - Error Prevention: This change directly addresses and prevents an
ImportErrorthat could occur during Python shutdown. The error was caused by unclosedaiohttpsessions attempting to accesssys.meta_pathafter it had been set toNoneduring interpreter cleanup.

Code Review
This pull request correctly addresses the ImportError that occurs during Python shutdown by replacing the flush() call with shutdown() in the atexit handler. This is the proper way to ensure the underlying PostHog client and its aiohttp sessions are cleanly terminated, preventing errors during interpreter teardown. The change is concise, well-described, and effectively resolves the reported issue.
While the fix itself is correct, I noticed a related issue in an area outside of this PR's changes: the TelemetryCollector class in telemetry.py appears to use a different get_telemetry function that does not register this atexit handler. This could potentially lead to the same shutdown issue for users of that specific compatibility class. This is something to consider for a future improvement to ensure consistent behavior.
Overall, this is a good fix and I approve of the changes.
