python-atexit-network-io

What problem does it solve?

This Skill resolves the issue of encountering "cannot schedule new futures after shutdown" errors when Python atexit handlers perform network I/O via async-backed sync clients, such as aiohttp/asyncio wrappers.

Core Features & Use Cases

• Fix atexit Network I/O Errors: Corrects the failure of atexit-registered handlers that call sync client methods with aiohttp/asyncio internally.
• Prevent Unclosed Client Session Warnings: Eliminates "Unclosed client session" and "Unclosed connector" warnings.
• Explicit Finalizer Call: Ensures the finalizer is called explicitly at the end of the main code path before interpreter teardown.

Quick Start

Implement the finalizer in your main code path, calling finalize_session() at the end of the __main__ block.
