Fails to import dlls which can't use TLS

[rkbennett]

Specifically, cryptography.hazmat.bindings._rust.pyd does not allow for TLS, but pythonmemorymodule forces use of TLS, not sure what the solution would be here, but it isn't compatible.

Hi, I was able to load _rust.pyd calling PyInit__rust using PythonMemoryModule.

The pyd has a TLS callback and it looks like it's correctly executed:

Can you elaborate on the issue you are facing?

[rkbennett]

I'm using python 3.11 and the pyd you get when you pip install OpenSSL with dependencies

[rkbennett]

I'll try to get a screenshot when I get back to my desk

[rkbennett]

This is what I'm seeing when I try to do the dll = pythonmemorymodule.MemoryModule(data=buf debug=True)

[rkbennett]

I've also tried importing it directly with _memimporter and it throws a different error

This one led me to do some searching and it appeared as though _rust wasn't meant to support TLS.

I was able to load _rust.pyd using Python 3.10.8 and pythonmemorymodule_wininet in the Pyramid dev branch.
Give it a try and let me know if that goes through also for you

[rkbennett]

I downloaded the pythonmemorymodule_wininet.zip file, extracted it and then imported it and tried again on python3.10.11 and still get the same error.

[naksyn]

I confirm that with version 3.10.10 and 3.10.8 you can successfully load the _rust.pyd contained in this archive

I don't know the nuances of _rust.pyd files compiled for other python versions. I usually stick with versions 3.10.x because that's what I tested the most.

[rkbennett]

How did you obtain that version of _rust.pyd?

[naksyn]

it's a freezed dependency for paramiko from late 2022. Check the about.py file, It's the cryptography package version 37.0.4, you can download it directly from PyPi.

[rkbennett]

Awesome, I'll take a look at that and give it a try
