Git：在裸仓库中更改Active Branch的正确方法？ [英] Git: Correct way to change Active Branch in a bare repository?

问题描述

我有一个裸仓库，用作我项目的中央商店。所有开发人员都可以使用 git clone< repo> 来与之共享。当他们完成克隆时，他们会得到master分支的结账（除非他们执行 git clone -n​​ ），因为 repo.git / HEAD code>包含 ref：refs / heads / master ，这是活动分支。



问题是，如何正确更改 Active Branch ？我可以简单地直接对 repo.git / HEAD 文件进行破解，但这看起来令人讨厌，而且很好，哈。

我在repo .git 目录中尝试了 git checkout< otherbranch> ，但是失败了，因为我没有' t

我试过 git update-ref HEAD refs / heads / otherbranch 但刚刚更新refs / heads / master与refs / heads / otherbranch相同（好的，我在一个虚拟库中做了一个，不是我的产品！）

我尝试过 git update-ref --no-deref HEAD refs / heads / otherbranch 并且几乎可以工作。它更新了 HEAD 文件，但是它将它设置为由 refs / heads / otherbranch 指向的提交的SHA1。 。

我正在使用git版本 1.7.0.2.msysgit.0 。

测试

我猜测没有办法通过 git push 来做到这一点，因为允许所有和各种改变你的默认分支似乎有点不安全（！），但是当然在repo .git 目录中有一个更好的方法，比直接破解 HEAD file。

解决方案

如果您有权访问远程裸回购，文章建议：

 git symbolic-ref HEAD refs / heads / mybranch 
  

这将更新仓库中的HEAD文件，使其包含：

  ref：refs / heads / mybranch 
  

记录在 git-symbolic-ref

如果您无法访问远程回购，请参阅我以前的回答。

请记住，像 git remote set-head ：

• 不更改远程存储库的默认分支。
  
  它只会将本地存储库中存储的远程跟踪分支更改为 refs / remotes /< name> / HEAD




• 不会变更 HEAD 本身（同样，只有 refs / remotes /< name> / HEAD ），因此需要
  git symbolic-ref 。

所以 git remote set-head 不是答案在这里。如果你有直接的访问远程仓库，
git symbolic-ref HEAD 就是。

I have a bare repository that's used as the central store for my project. All the developers do git clone <repo> to share with it. When they do the clone, they get a checkout of the master branch (unless they do git clone -n) because repo.git/HEAD contains ref: refs/heads/master, making this the Active Branch.

The question is, how do I change the Active Branch properly? I could simply hack the repo.git/HEAD file directly, but that seems nasty and, well, hacky.

I tried doing git checkout <otherbranch> in the repo .git directory, but that failed because I wasn't in a work tree.

I tried git update-ref HEAD refs/heads/otherbranch but that just updated refs/heads/master to be the same as refs/heads/otherbranch (okay, I did that one in a dummy repository, not my production one!)

I tried git update-ref --no-deref HEAD refs/heads/otherbranch and that almost worked. It updated the HEAD file, but it set it to the SHA1 of the commit pointed to by refs/heads/otherbranch.

I'm testing with git version 1.7.0.2.msysgit.0.

I'm guessing there's no way to do this through git push, as allowing all and sundry to change your default branch seems a bit unsafe (!), but surely there's a better way to do it in the repo .git directory than directly hacking the HEAD file.

解决方案

If you have access to the remote bare repo, this article suggests:

git symbolic-ref HEAD refs/heads/mybranch

Which will update the HEAD file in your repository so that it contains:

ref: refs/heads/mybranch

as documented in the git-symbolic-ref

---

If you don't have access to the remote repo, see my previous answer.

---

Remember that a command like git remote set-head:

• doesn't change the default branch of the remote repo.
  It only changes a remote tracking branch stored in your local repo as refs/remotes/<name>/HEAD

• doesn't change HEAD itself (again, only refs/remotes/<name>/HEAD), hence the need for git symbolic-ref.

So git remote set-head is not the answer here.
git symbolic-ref HEAD is, if you have direct access to the remote repo.
