python3 image seems to work with ctypes, docs say otherwise

[MShekow]

Describe the bug
The docs claim that ctypes is not supported.

To Reproduce
Using ctypes works just fine.

Following some commands from the official docs:

Start a container: docker run --rm -it gcr.io/distroless/python3 then type this in:

from ctypes import *
libc = CDLL("libc.so.6")
print(libc.rand())

Expected behavior

ctypes calls should not work.

I'm not a python user, if you know the underlying reason, that'd be useful knowledge to share and we can update the docs.

[MShekow]

No, I don't. While I'm a Python user, I don't fiddle with low-level details such as "loading of system libraries" and why that would (not) work.

I'm curious how you are asking that question, given that Git claims that it was you who introduced this note about ctypes ;) - see 9e62fd2

[loosebazooka]

Yeah it's possible that I was just advised about that at the time... Either something changed or I was just wrong. I think the path forward is finding the right answer though.
