Please describe the problem.

git annex push does not trigger git credential retrieval reliably, but forces manual credential entry.

What steps will reproduce the problem?

I have the following git-credential setup

[credential]
        helper = cache --timeout 21600
        helper = oauth

Most of my remotes are on some forgejo-aneksajo site. This setup makes git perform an oauth2 workflow against forgejo, and then use the cached credential for a couple of hours. I find this convenient.

git-annex usage also benefits from this setup, as it appears to be able to use a cached credential fine.

But when a credential is not yet cached, the oauth workflow is not triggered when git-annex needs a credential. Instead, it causes a prompt:

❯ git annex push
copy vid/trr379-metadata-website-update.mp4 (to origin...) Password for 'https://oauth2@<host>':

When I ctrl-c that and immediately afterwards run git-push, this is happening:

❯ git push
Please complete authentication in your browser...
https://<host>/login/oauth/authorize?client_id=a4792ccc-...&code_challenge=mHvQCJU...&code_challenge_method=S256&redirect_uri=http%3A%2F%2F127.0.0.1%3A43407&response_type=code&state=QTFf...
...
To https://<host>/<repo>.git
   0ee8c89..4977dac  main -> main

Afterwards, git-annex-push runs fine too.

❯ git annex push
copy vid/trr379-metadata-website-update.mp4 (to origin...) 
ok                                
(recording state in git...)
push origin 
Everything up-to-date
...
remote: 
remote: Create a new pull request for 'synced/git-annex':
remote:   https://<host>/<repo>/compare/main...synced/git-annex
remote: 
remote: 
remote: Create a new pull request for 'synced/main':
remote:   https://<host>/<repo>/compare/main...synced/main
remote: 
To https://<host>/<repo>.git
   aec36a7..18aa9ab  git-annex -> synced/git-annex
   0ee8c89..4977dac  main -> synced/main
ok

My expectation would be that a git-annex push would be able to trigger the oauth workflow in the same way that Git does.

What version of git-annex are you using? On what operating system?

git-annex version: 10.20260316-gf01ba218ffb36e8607516d9895dfaeaeaf101a05 on Debian forky/sid
