git 如何处理来自两个不同远程仓库的相同分支名称？

Question

如果我使用 git remote add 为一个 repo 设置了两个 remote，并且这两个 repo 包含一个同名的分支。当我使用 git checkout?

切换到它时，git 如何知道我打算使用哪个 repo 的哪个分支

Answer 1

How does git know which branch of which repo I intend to use when I switch to it using git checkout?

没有。通常，如果存在歧义，例如在这种情况下，两个遥控器（"origin" 和 "upstream2"）都有一个 devel 分支：

$ git branch -a
* master
  remotes/origin/HEAD -> origin/master
  remotes/origin/devel
  remotes/origin/master
  remotes/upstream2/devel
  remotes/upstream2/master

如果我只是尝试 git checkout devel 我得到：

$ git checkout devel
error: pathspec 'devel' did not match any file(s) known to git.

我需要说清楚：

$ git checkout -b devel remotes/upstream2/devel
Branch devel set up to track remote branch devel from upstream2 by rebasing.
Switched to a new branch 'devel'

将此与我只有一个遥控器的情况进行比较：

$ git branch -a
* master
  remotes/origin/HEAD -> origin/master
  remotes/origin/devel
  remotes/origin/master

然后：

$ git checkout devel
Branch devel set up to track remote branch devel from origin by rebasing.
Switched to a new branch 'devel'
