1. 需求

Git仓库地址改变，需要代码迁移，但需要保留之前开发人员的提交记录，方便回溯

git clone  --bare 生成的文件夹名称会多出一个.git

git clone  --bare 解释

--bare

Make a bare Git repository. That is, instead of creating  and placing the administrative files in /.git, make the  itself the $GIT_DIR.

This obviously implies the -n because there is nowhere to check out the working tree.

Also the branch heads at the remote are copied directly to corresponding local branch heads, without mapping them to refs/remotes/origin/.

When this option is used, neither remote-tracking branches nor the related configuration variables are created.

git push --mirror 解释

--mirror

Instead of naming each ref to push, specifies that all refs under refs/ (which includes but is not limited to refs/heads/, refs/remotes/, and refs/tags/) be mirrored to the remote repository.

Newly created local refs will be pushed to the remote end, locally updated refs will be force updated on the remote end, and deleted refs will be removed from the remote end.

This is the default if the configuration option remote..mirror is set.
