Issue type: Bug
Clarity: Mostly clear
Activity status: Stale
Tech stack: git, python
Domain: authentication, backend

Research direction

Start by comparing the pygit2 1.13.3 and 1.14.0 credentials APIs, focusing on the import in scmrepo/git/backend/pygit2/callbacks.py. Reproduce an HTTP clone with username and password, then verify that authentication works with pygit2 1.14.0 without the reported ImportError.

Written by the indexing model from the issue text.

Description

Upgrading to 1.14.0, and cloning via HTTP auth (username + password) gives this stack trace:

  File "/opt/conda/lib/python3.10/site-packages/pygit2/remotes.py", line 171, in ls_remotes
    self.connect(callbacks=callbacks, proxy=proxy)
  File "/opt/conda/lib/python3.10/site-packages/pygit2/remotes.py", line 120, in connect
    payload.check_error(err)
  File "/opt/conda/lib/python3.10/site-packages/pygit2/callbacks.py", line 93, in check_error
    raise self._stored_exception
  File "/opt/conda/lib/python3.10/site-packages/pygit2/callbacks.py", line 416, in wrapper
    return f(*args)
  File "/opt/conda/lib/python3.10/site-packages/pygit2/callbacks.py", line 484, in _credentials_cb
    ccred = get_credentials(credentials, url, username, allowed)
  File "/opt/conda/lib/python3.10/site-packages/pygit2/callbacks.py", line 569, in get_credentials
    creds = fn(url_str, username_str, allowed)
  File "/opt/conda/lib/python3.10/site-packages/scmrepo/git/backend/pygit2/callbacks.py", line 51, in credentials
    from pygit2.credentials import GIT_CREDENTIAL_USERPASS_PLAINTEXT, UserPass
ImportError: cannot import name 'GIT_CREDENTIAL_USERPASS_PLAINTEXT' from 'pygit2.credentials' (/opt/conda/lib/python3.10/site-packages/pygit2/credentials.py)

Version 1.13.3 works fine though :).

Thanks.
