[git] git clone –mirror && git clone –bare

Method A : git clone –mirror
Method B : git clone –bare

Method A :
git clone –mirror to local
Go to another folder, git clone form local repository.
git push to local repository.
Go to local repository then type git push to push the commit to remote.

[core]
    repositoryformatversion = 0
    filemode = true
    bare = true
[remote "origin"]
    url = ssh://happy@168.95.1.1/home/happy/git/test
    fetch = +refs/*:refs/*
    mirror = true

Method B :
git clone –bare to local
Go to another folder, git clone form local repository.
git push to local repository.
Go to local repository then type git push to push the commit to remote.

[core]
    repositoryformatversion = 0
    filemode = true
    bare = false
    logallrefupdates = true
[remote "origin"]
    url = ssh://happy@168.95.1.1/home/happy/git/test
    fetch = +refs/heads/*:refs/remotes/origin/*
[branch "master"]
    remote = origin
    merge = refs/heads/master

Compare :

method A
When I git push under method A. git push no ask any question.

method B
When I git push under method B. git push ask question and type following command at the first push.
git push –set-upstream origin master

After push you can find log have keywork "merge". Because git clone --bare clone the repository to become a independent one. So even remote and local repository are the same content. When push from local to remote need to merge together. But mirror don't need.
That is the different.
