"git remote show origin":为什么所有分支都显示"tracked"即使有些不是呢?

问题描述：

即使那些分支未链接到本地​​分支进行拉/推，为什么"git remote show origin"仍将远程分支列为已跟踪"?在这种情况下，跟踪"是否意味着其他含义?我认为这就是"tracked"的全部意思:有关分支跟踪的git文档.

Why does "git remote show origin" list remote branches as "tracked" even when those branches are not linked to a local branch for pull/push? Does "tracked" mean something else in this context? I thought that was the whole meaning of "tracked": git docs on branch tracking.

1)克隆具有多个远程分支的存储库

1) clone a repo with more than one remote branch

2)运行git remote show origin-表示已跟踪"testBranch".但是git branch -vv正确显示仅母版跟踪源/母版，而git branch -a正确显示仅一个本地分支母版.

2) run git remote show origin -- says "testBranch" is tracked. But git branch -vv correctly shows only master tracking origin/master, and git branch -a correctly shows that there's only the one local branch, master.

3)那么:git remote show origin将testBranch列为"tracked"是什么意思?需要明确的是:事情的设置没有错误":一切正常.我只是不明白为什么将远程testBranch标记为已跟踪".这就是我想要的答案.

3) So: what does git remote show origin mean when it lists testBranch as "tracked"? To be clear: there's nothing "wrong" with how things are setup: everything works fine. I just don't understand why the remote testBranch is labeled as "tracked". That's what I want an answer to.

hawk@Tug:~/temp/TestRepo (master)$ git remote show origin
* remote origin
  Fetch URL: git@github.com:haughki/TestRepo.git
  Push  URL: git@github.com:haughki/TestRepo.git
  HEAD branch: master
  Remote branches:
    master     tracked
    testBranch tracked
  Local branch configured for 'git pull':
    master merges with remote master
  Local ref configured for 'git push':
    master pushes to master (up to date)
hawk@Tug:~/temp/TestRepo (master)$ git branch -vv
* master 8df130e [origin/master] shoulda done this last time
hawk@Tug:~/temp/TestRepo (master)$ git branch -a
* master
  remotes/origin/HEAD -> origin/master
  remotes/origin/master
  remotes/origin/testBranch

答

git remote show提到的跟踪"与git branch -vv所说的跟踪"不同，发生在git checkout -b <branch> <upstream>上. (或者不同"一词太强了，因为基本思想是相同的，它是在谈论存储库中的远程跟踪分支，而不是您是否有一个本地分支恰好将其中一个作为上游分支)

The "tracked" that git remote show mentions is different from the "tracking" that git branch -vv talks about, that occurs with git checkout -b <branch> <upstream>. (Or maybe "different" is too strong a word, since the underlying idea is the same, it's talking about the remote-tracking branches in your repository, rather than whether you have a local branch that happens to have one of those as its upstream.)

尤其是，git remote show检查给定遥控器的fetch =行，并将其与遥控器上现在实际可用的参考进行比较(运行git ls-remote来查看这些参考).

In particular, git remote show examines the fetch = line(s) for the given remote, and compares this with the references actually available now on the remote (run git ls-remote to see those).

名为origin的远程服务器的默认fetch =行显示为:

The default fetch = line for the remote named origin reads:

fetch = +refs/heads/*:refs/remotes/origin/*

请注意两个*.左侧的一个匹配远程存在的所有分支，而右侧的一个则表示替换与左侧匹配的相同名称".

Note the two *s. The one on the left matches all branches that exist on the remote, while the one on the right means "replace with the same name matched on the left".

假设远程origin当前具有以下引用:

Suppose that remote origin currently has the following refs:

refs/heads/master
refs/heads/newbr
refs/tags/v1.2
refs/notes/commits

进一步假设分支newbr自上次克隆，获取或以其他方式与远程origin进行对话以来是新的，因此git branch -r仅列出origin/master，而不列出origin/newbr.

Suppose further that branch newbr is new since the last time you cloned, fetched, or otherwise talked to remote origin, so that git branch -r will only list origin/master, not origin/newbr.

如果您现在运行git remote show origin，您将获得此位(以及其他内容):

If you now run git remote show origin you will get (along with the other stuff) this bit:

    master tracked
    newbr  new (next fetch will store in remotes/origin)

这意味着两个分支都匹配，并且您已经有refs/remotes/origin/master，但是您还没有refs/remotes/origin/newbr.

This means that both branches match, and you already have refs/remotes/origin/master, but you do not yet have refs/remotes/origin/newbr.

运行git fetch后，您将获得origin/newbr.但是，如果在运行git fetch之前更改了fetch =行，从而使不会获取origin/newbr，则git remote show origin将停止提及它.

Once you run git fetch, you will acquire origin/newbr. But if, before you do run git fetch, you change your fetch = line so that you won't acquire origin/newbr, git remote show origin will stop mentioning it.
