DXL Client Python3.12 Patch

This outlines how to patch the dependencies of the opendxl-python client for python3.12

Basic virtual env

Set up your python virtual environment. Install setuptools using pip.

Edit collections init file

In [python_install_path]/collections/_init__.py, change:

import collections.abc as _collections_abc

to:

import collections
try:
    from collections.abc import Callable
    _collections_abc = collections.abc
except ImportError:
    from collections import Callable
import sys as _sys

This change is made to deal with _collections_abc now being held in module collections.abc but still being referenced as _collections_abc frequently in code.

Libcrypto modification

In [python_install_path]/site-packages/oscrypto-1.3.0-py1.12.egg/oscrypto/_openssl/_libscrypto_ctypes.py change these lines:

version_match = re.search('\\b(\\d\\.\\d\\.\\d[a-z]*)\\b', version_string)
if not version_match:
    version_match = re.search('(?<=LibreSSL )(\\d\\.\\d(\\.\\d)?)\\b', version_string)
if not version_match:
    raise LibraryNotFoundError('Error detecting the version of libcrypto')
version = version_match.group(1)
version_parts = re.sub('(\\d)([a-z]+)', '\\1.\\2', version).split('.')
version_info = tuple(int(part) if part.isdigit() else part for part in version_parts)

to:

version_match = re.search(r'\b(\d+\.\d+\.\d+[a-z]*)\b', version_string)
if not version_match:
    # Attempt to match LibreSSL version format
    version_match = re.search(r'(?<=LibreSSL )(\d+\.\d+(\.\d+)?)\b', version_string)
if not version_match:
    raise RuntimeError(f'Error detecting the version of libcrypto from: {version_string}')
version = version_match.group(1)
version_parts = re.sub(r'(\d)([a-z]+)', r'\1.\2', version).split('.')
version_info = tuple(int(part) if part.isdigit() else part for part in version_parts)

This change is needed to capture the new version output string format of LibreSSL.

Install dxlbootstrap

Use pip to install dxlbootrap.

Conclusion

With these steps, you should now be able to run dxlclient provisionconfig [SERVER_IP] [CLIENT_NAME] which is used to create a config file that can be used by the opendxl client.
