Should it be possible to import ssl?

[sggaffney]

A package that I'd like to use imports 'ssl'. Could you please advise if there is any way to make this available to a zeus-python kernel in jupyterlite? When I run import ssl in the demo notebook (https://jupyterlite.github.io/xeus-python-demo/retro/notebooks/?path=demo.ipynb), the traceback includes:

File /lib/python3.10/ssl.py:98
95 from collections import namedtuple
96 from enum import Enum as _Enum, IntEnum as _IntEnum, IntFlag as _IntFlag
---> 98 import _ssl # if we can't import it, let the error propagate
100 from _ssl import OPENSSL_VERSION_NUMBER, OPENSSL_VERSION_INFO, OPENSSL_VERSION
101 from _ssl import _SSLContext, MemoryBIO, SSLSession
ModuleNotFoundError: No module named '_ssl'

I've tried adding openssl to dependencies in the environment.yml file, but get the same result (and it breaks the rule of having a 'noarch' version').

File /lib/python3.10/ssl.py:98

Not sure, but this is on a very old stack, and the python3.11 build has some more features.

@sggaffney are you able to try jupyterlite-xeus-python v1.0.0a3?

[sggaffney]

Thank you for the suggestion. I've just tried that and get the same error when I run jupyter lite serve in an empty directory and run import ssl in a new notebook. (File /lib/python3.11/ssl.py:100, ModuleNotFoundError: No module named '_ssl')

My environment file, for reference, was:

name: build-env
channels:
  - conda-forge
dependencies:
  - python  # resolved to v3.12.0
  - pip
  - jupyter_server  # resolved to v2.11.2
  - jupyterlite-core  # resolved to v0.2.1
  - pip
  - pip:
    - --pre
    - jupyterlite-xeus-python==1.0.0a3

I'm using an arm64 Mac, fyi. The jupyter lite build/serve step installed:

This still seems to be the case with the latest versions.

I need ssl to work. A lot of the packages I install use ssl under the hood 😓

we need to port this recipe to emscripten-forge https://github.com/pyodide/pyodide/blob/main/packages/ssl/meta.yaml
