[New-bugs-announce] [issue26590] socket destructor: implement finalizer

[STINNER Victor]

New submission from STINNER Victor:

The PEP 442 helped to make object finalization safer, but it's just an API, it's not widely used in the Python core yet. io.FileIO has a nice implementation, but socket.socket and os.scandir don't.

I noticed this while working on the issue #26567 which indirectly resurected a destroyed socket (in test_socket).

As I workaround, I reverted my change on socket destructor, but I'm interested to enhance socket destructor to be able to use the new tracemalloc feature of the warnings module.
