I've been looking around the internet and can't find what this does:
git push origin master:refs/heads/master
What is the difference with just plain:
git push origin master
In versions of git before v18.104.22.168 there was an important difference between these commands. You needed to use the full name of the ref on the destination side of the refspec if that branch did not already exist. (The commit that changed this behaviour has an interesting description of the change.)
In current versions of git there is no difference between the two, as long as
master is unambiguous in the destination repository - this is almost always the case, unless you've done something deliberately confusing like create a tag called
master. When you do
git push origin master, git tries to interpret
master as a refspec. Since this refspec has no
: separating the source and destination refs, it assumes by default that you mean:
git push origin master:master
... and those incomplete ref names are expanded to
refs/heads/master on both sides (again, as long as
master is unambiguous both in the source and destination repositories).
There is no difference. One is just a more verbose version of the other.
master:refs/head/masteris saying push your local
master to the remotes
