It took me 1 year, a few sleepless nights, multiple attempts to understand the leak, but I eventually found it! WSASend() doesn't release the memory if it fails immediately. I wrote PR 11469 to fix the memory leak. ReadFile() has the same bug, I also fixed it. By the way, the _overlapped.Overlapped type has no traverse function: it may help the garbage collector to add once, since asyncio is famous for building reference cycles by design (Future.set_exception()). ---------- _______________________________________ Python tracker <rep...@bugs.python.org> <https://bugs.python.org/issue32710> _______________________________________ _______________________________________________ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
