问题描述
我必须Git仓库repo1和repo2. repo1中有三个分支master，alpha和beta. repo2从repo1克隆.
I have to Git repos repo1 and repo2. There are three branches master, alpha and beta in repo1. repo2 clones from repo1.
在repo2中，我可以看到带有git branch -a的远程跟踪分支:
In repo2, I can see remote tracking branches with git branch -a:
remotes/origin/HEAD -> origin/master
remotes/origin/master
remotes/origin/alpha
remotes/origin/beta
但是repo2中的文件夹.git/refs/remotes/origin/只有一个文件HEAD，其内容为:
But the folder .git/refs/remotes/origin/ in repo2 only has a single file HEAD, whose content is:
ref: refs/remotes/origin/master
因此，此HEAD是符号引用.但是为什么它指向不存在的引用呢?顺便说一句，repo2在何处存储alpha和beta的信息? (repo2知道alpha和beta，因为它在git branch -a中显示它们.)
So this HEAD is a symbolic ref. But why does it point to a ref that doesn't exist? BTW, where does repo2 store the information of alpha and beta? (repo2 knows alpha and beta because it displays them in git branch -a.)
推荐答案
引用可能已打包"在.git/packed-refs中.
The refs are probably "packed" in .git/packed-refs.
