Git Push error: refusing to update checked out branch

Hi I have solved some merge conflicts, committed then tried to Push my changes and received the following error:

c:\Program Files (x86)\Git\bin\git.exe push --recurse-submodules=check "origin" master:master
Done
remote: error: refusing to update checked out branch: refs/heads/master
remote: error: By default, updating the current branch in a non-bare repository
remote: error: is denied, because it will make the index and work tree inconsistent
remote: error: with what you pushed, and will require 'git reset --hard' to match
remote: error: the work tree to HEAD.
remote: error:
remote: error: You can set 'receive.denyCurrentBranch' configuration variable to
remote: error: 'ignore' or 'warn' in the remote repository to allow pushing into
remote: error: its current branch; however, this is not recommended unless you
remote: error: arranged to update its work tree to match what you pushed in some
remote: error: other way.
remote: error:
remote: error: To squelch this message and still keep the default behaviour, set
remote: error: 'receive.denyCurrentBranch' configuration variable to 'refuse'.
To C:/Development/GIT_Repo/Project
! [remote rejected] master -> master (branch is currently checked out)
error: failed to push some refs to 'C:/Development/GIT_Repo/Project'


Does anyone know what could be causing this error?

Thanks

Answer

There are two types of repositories: bare and non-bare

Bare repositories do not have a working copy and you can push to them. Those are the types of repositories you get in Github! If you want to create a bare repository, you can use

git init --bare

So, in short, you can't push to a non-bare repository (Edit: Well, you can't push to the currently checked out branch of a repository. With a bare repository, you can push to any branch since none are checked out. Although possible, pushing to non-bare repositories is not common). What you can do, is to fetch and merge from the other repository. This is how the pull request that you can see in Github works. You ask them to pull from you, and you don't force-push into them.


Update: Thanks to VonC for pointing this out, in the latest git versions (currently 2.3.0), pushing to the checked out branch of a non-bare repositories is possible. Nevertheless, you still cannot push to a dirty working tree, which is not a safe operation anyway.
