Encountering Python crash on numerous client connects to socketserver
On the SMPS package, I've refactored a bit since the last blog post, and I also encountered what looks like a bug in Python.Python can randomly crash if too many client connections are made to the socketserver, and it crashes in such a way that it is difficult for me as a regular Python programmer to understand what the problem could be.
So although I was tempted to do a bit of C debugging and poke around, I do have limited time and energy, so I did the smart thing and patched it up so that it is easy to reproduce the problem:
https://github.com/morphex/smps/commit/59fbc78ebddcc3a68c6ea...
and then I created an issue in the Python bug tracker:
https://github.com/python/cpython/issues/95204
[Added later:] Aha. So it turns out I was quitting threads, and this gave an unclear error message. Thanks to Jeff Epler for pointing that out.
That got worked on in this commit:
https://github.com/morphex/smps/commit/9b539075627dd2016fca6a98f70913f21671e072
and the parent commit. Now with > 400 test connections I get an SSL handshake timeout, but, that's in ssl.c and probably due to some configuration setting somewhere.
