Is "refs/heads/master" same as "refs/remotes/origin/master" in Git?
提问by Tower
The question is simple: is refs/heads/masterthe same thing as refs/remotes/origin/master? If it is not in some cases, how can I know when it is not and what it is then?
问题很简单：refs/heads/master与refs/remotes/origin/master? 如果在某些情况下不是，我怎么知道什么时候不是，然后是什么？

They are two different symbolic names that can point to different things. refs/heads/masteris a branch in your working copy named master. Frequently that is a tracking branch of refs/remotes/origin/masterbecause originis the default name for the remote created by git cloneand its primary branch is usually also named master.
它们是两个不同的符号名称，可以指向不同的事物。 refs/heads/master是工作副本中名为master. 通常这是一个跟踪分支，refs/remotes/origin/master因为它origin是远程创建的默认名称git clone，其主要分支通常也命名为master。
You can see the difference between them with git rev-list refs/heads/master..refs/remotes/origin/masterwhich will be empty if they are the same and will otherwise list the commits between them.
您可以看到它们之间的区别，git rev-list refs/heads/master..refs/remotes/origin/master如果它们相同，它将为空，否则将列出它们之间的提交。

The key difference to understand is that the branches under refs/heads/are branches that, when you have one checked out, you can advance by creating new commits. Those under refs/remotes/, however, are so-called "remote-tracking branches" - these refs just point to the commit that a remote repository was at the last time you did a git fetch <name-of-remote>, or a successful git pushto the corresponding branch in that remote repository. (I wrote a blog post that talks about this difference at some length here.)
要理解的主要区别在于，下面的分支refs/heads/是分支，当您签出一个分支时，您可以通过创建新提交来推进。refs/remotes/但是，在 下的那些是所谓的“远程跟踪分支” - 这些引用仅指向远程存储库在您上次执行git fetch <name-of-remote>或 成功git push时对该远程存储库中的相应分支进行的提交。（我写了一篇博客文章，在这里详细讨论了这种差异。）
