为什么 git push all 不需要远程上游分支

Question

I created a new branch on my local repo and added a commit to it and then pushed it (along with changed on the master) to my remote repo using git push --all , which works fine, ie it created a new remote branch with the same name as my local branch and pushed the changes there.

However, when using git push whilst having the new branch checked out, it get the fatal: The current branch ... has no upstream branch. error.

Why does git push --all assume a default branch and git push doesn't?

Answer 1

The documentation for git push indicates that --all will assume defaults for all branches. https://git-scm.com/docs/git-push

--all: Push all branches (ie refs under refs/heads/); cannot be used with other <refspec>.

It's not the same for vanilla git push . You can, however, specify something like the following in your git configuration to make git push default to the current branch.

[push]                   
    default = current
