Deleting branch with repo abandon and git branch -D
提问by mrutyunjay
I am using git and git-repofor my project. I see when I try to delete my local branch which I am currently on using git command
我正在为我的项目使用 git 和git-repo。当我尝试删除我当前使用 git 命令的本地分支时，我看到了
git branch -D branch_name
It shows me error which I am expecting, as we can't delete current branch.
它显示了我期望的错误，因为我们无法删除当前分支。
But if I use repo command
但是如果我使用 repo 命令
repo abandon branch_name
I am able to delete the current branch. So my question is what command is repo using internally to delete the branch?
我可以删除当前分支。所以我的问题是 repo 在内部使用什么命令来删除分支？

The abandon.pysubcmdcalls project.AbandonBranch, which includes:
该abandon.pysubcmd调用project.AbandonBranch，其中包括：
head = self.work_git.GetHead()
if head == rev:
# We can't destroy the branch while we are sitting
# on it. Switch to a detached HEAD.
#
head = all_refs[head]
revid = self.GetRevisionId(all_refs)
if head == revid:
_lwrite(os.path.join(self.worktree, '.git', HEAD),
'%s\n' % revid)
else:
self._Checkout(revid, quiet=True)
In other words, it makes sure to notbe on the branch you are deleting, even if that mean setting up a detached HEAD(by a checkout of a SHA1 'revid').
换句话说，它确保不在您要删除的分支上，即使这意味着设置一个分离的 HEAD（通过检查 SHA1 ' revid'）。
