描述

In our service we had aiohttp==3.8.5 and upgraded aiohttp to 3.10.5 version. That is all. In production now we have issues like issue below.
Maybe i should to write issue to another libs, tell me about it if so, or maybe you have your own fix then tell me uvloop version i need to upgrade in my service.

traceback:

研究方向

從 uvloop/loop.pyx 中的 traceback 進入點開始,尤其是 _ensure_fd_no_transport 和 _add_writer,接著針對回報的相依套件版本,將它們與 aiohttp/connector.py 和 aiohappyeyeballs/impl.py 進行比較。使用 Debian 12 上的 Python 3.10.15,以及 uvloop 0.19.0 和 aiohttp 3.10.5,重現 file-descriptor 衝突;完成的標準是找出可重現的原因,並提供回歸測試或有文件記錄的相容性修正。
