Memory leak when using BuiltinSSLAdapter

[bmourgues]

Hello,

you can reproduce this issue on Debian bookworm (12.5)

• python version 3.11.2
• cheroot version 9.0.0

I also managed to reproduce the same issue with cheroot version 10.0.0 in a virtual environment on the same system.

No log or console log, as everything works fine, but this memory leak

If needed, you can generate your certificate with following command :
openssl req -x509 -newkey rsa:2048 -nodes -keyout server.key -days 365 -out server.crt

After further investigation the leak appeared in version 8.3.0
Older versions do not seem to leak.

We suspect BuiltinSSLAdapter.get_environ(self, sock) method to be the root cause.
Removing all code in this method except the first dict creation, seems to solve leak issue.

I hope this may help you to target the problem ...

Hello. Is this reproducible with a distro-default Python in any official/public container image? I'd rather not have a repro dependent on compiling CPython from scratch.

Is there a console log output that you can share?
