Thanks, it really helped to understand.
Since what I want to do is to run git pull/push from within a script in a Jenkins job and Jenkins already has the git user&password stored, I thougth is odd to store them at a git credential helper.
My solution is running (before git pull/push):
    git config remote.origin.url https://$GIT_USER:$GIT_PASSWORD@bitbucket.org/...
while at the start of the script trapping EXIT signal and resetting origin as following:
    trap "sudo git config remote.origin.url https://$GIT_USER@bitbucket.org/..." EXIT
Make sense or am I missing something?

Thanks in advance,
Bentzy Sagiv

Since you didn't specify a remote here, Git assumes origin. It uses your configured "push.default" behavior ("simple" by default) to determine which refs to push and pushes your master branch to the origin's master branch. Since it _knows_ it pushed to origin, it updates your local "refs/remotes/origin/master" ref with the same commit it just pushed, resulting in an "up-to-date" message.

This, on the other hand, _is not pushing to a configured remote_. It's pushing to an explicit URL, which happens to match the URL of a configured remote. But it's still not a configured remote. It's using origin's URL, but you didn't push to origin. As a result, "refs/remotes/origin/master" is not updated, and you get an "ahead" message.

Everything here is working as intended. If you want to push to a
_remote_, you either need to:
- Name the remote ("git push origin"), or
- Leave it off, so Git will assume origin ("git push")

Pushing to a URL that matches a remote's URL is _not_ pushing to a remote. It's pushing to an explicit URL.

Hope this helps, Bryan Turner
