One day I got an error:
$ git push
warning: You did not specify any refspecs to push, and the current remote
warning: has not configured any push refspecs. The default action in this
warning: case is to push all matching refspecs, that is, all branches
warning: that exist both locally and remotely will be updated. This may
warning: not necessarily be what you want to happen.
warning:
warning: You can specify what action you want to take in this case, and
warning: avoid seeing this message again, by configuring 'push.default' to:
warning: 'nothing' : Do not push anything
warning: 'matching' : Push all matching branches (default)
warning: 'tracking' : Push the current branch to whatever it is tracking
warning: 'current' : Push the current branch
But usually I want to push only branch I’m currently working with, so I need to setup push.tracking
$ git config --global push.default tracking
$ git push
