gitエラー「refusing to update checked out branch」の回避法

「checked out branch」を「bare repo」に変換することによって「refusing to update checked out branch」などのエラーが出ないようにできる。

$ git push origin master

...

error: refusing to update checked out branch: refs/heads/master

error: By default, updating the current branch in a non-bare repository

error: is denied, because it will make the index and work tree inconsistent

error: with what you pushed, and will require 'git reset --hard' to match

error: the work tree to HEAD.

error: 

error: You can set 'receive.denyCurrentBranch' configuration variable to

error: 'ignore' or 'warn' in the remote repository to allow pushing into

error: its current branch; however, this is not recommended unless you

error: arranged to update its work tree to match what you pushed in some

error: other way.

error: 

error: To squelch this message and still keep the default behaviour, set

error: 'receive.denyCurrentBranch' configuration variable to 'refuse'.

To git.example.com:/home/git/yoyodyne

 ! [remote rejected] master -> master (branch is currently checked out)

error: failed to push some refs to 'git.example.com:/home/git/yoyodyne'

いつごろからか、古いrepoへプッシュしようとするとこういうメッセージが出るようになった。checkoutしてあるrepoへのプッシュしちゃいけないポリシーになったようだ。

checkoutされているrepoをbare repositoryにする

repo$ mv    yoyodyne    yoyodyne.outer

repo$ mv    yoyodyne.outer/.git    yoyodyne

repo$ rmdir   yoyodyne.outer/

repo$ cd   yoyodyne

repo$ git   config   --bool   core.bare   true

で再びトライ：

$ git push origin master

repoをbareにしたらプッシュできるようになった。めでたしめでたし。
