你让我拉而不告诉我你要合并哪个分支

TL; DR:我有一个“跟踪”的分支,我无法拉动。

所以我在这里“斗斗4”:

$ git branch -v
  bucket-1       410f7b5 * gh-53 * gh-48 * "Share App"
  bucket-2       7ed70a2 * upgrade to SOLR 3.3.0
  bucket-3       400ffe4 * emergency fix prod issue
* bucket-4       64c2414 Merge branch 'bucket-3' into bucket-4
  master         8dc4854 [ahead 1] * gh-73

我想从我的遥控器中提取更改:

$ git pull

You asked me to pull without telling me which branch you
want to merge with, and 'branch.bucket-4.merge' in
your configuration file does not tell me, either. Please
specify which branch you want to use on the command line and
try again (e.g. 'git pull <repository> <refspec>').
See git-pull(1) for details.

If you often merge with the same branch, you may want to
use something like the following in your configuration file:

    [branch "bucket-4"]
    remote = <nickname>
    merge = <remote-ref>

    [remote "<nickname>"]
    url = <url>
    fetch = <refspec>

See git-config(1) for details.
嗯,奇怪,我以为我已经添加了“bucket-4”作为跟踪分支。我们来看看:

$ git remote show origin
* remote origin
  Fetch URL: git@github.com:abcd/main.git
  Push  URL: git@github.com:abcd/main.git
  HEAD branch (remote HEAD is ambiguous, may be one of the following):
    bucket-3
    master
  Remote branches:
    bucket-1       tracked
    bucket-2       tracked
    bucket-3       tracked
    bucket-4       tracked
    master         tracked
  Local branches configured for 'git pull':
    bucket-1       merges with remote bucket-1
    bucket-2       merges with remote bucket-2
    bucket-3       merges with remote bucket-3
    master         merges with remote master
  Local refs configured for 'git push':
    bucket-1       pushes to bucket-1       (up to date)
    bucket-2       pushes to bucket-2       (up to date)
    bucket-3       pushes to bucket-3       (up to date)
    bucket-4       pushes to bucket-4       (local out of date)
    master         pushes to master         (fast-forwardable)

实际上,bucket-4被标记为“已跟踪”,但不知何故,它被配置为推送,但不是拉动。

查看我的.git/config文件,我发现我的大多数分支机构都有“远程”和“合并”条目,但对于bucket-4则没有。如果没有这个,它甚至被视为“跟踪”?

[remote "origin"]
    url = git@github.com:abcd/main.git
    fetch = +refs/heads/*:refs/remotes/origin/*
[branch "master"]
    remote = origin
    merge = refs/heads/master
[branch "rel-2011-07-07"]
    remote = origin
    merge = refs/heads/rel-2011-07-07
[branch "bucket-1"]
    remote = origin
    merge = refs/heads/bucket-1
[branch "bucket-2"]
    remote = origin
    merge = refs/heads/bucket-2
[branch]
    autosetupmerge = true
[branch "bucket-3"]
    remote = origin
    merge = refs/heads/bucket-3

我看到这里可能的解决方案是在我的配置文件中为bucket-4添加remote/merge条目。但如果没有这个被认为是“跟踪”的呢? bucket-4是在本地创建的,然后从这个repo推送到服务器,所以我怀疑我没有为这个分支正确设置跟踪。

我是否可以添加一些配置,以便将来所有本地分支机构都能正确跟踪其遥控器?

它说bucket-4 pushes to bucket-4只是因为推送分支时的默认设置是将其推送到遥控器上具有匹配名称的分支。 (请注意,这仍然是默认设置,即使本地分支正在跟踪远程跟踪分支,并且远程跟踪分支对应于远程存储库中具有不同名称的分支。)

bucket-4中设置bucket-4origin之间关联的最简单方法是确保下次推送时:

git push -u origin bucket-4

或者,您可以这样做:

git branch --set-upstream-to origin/bucket-4

直接回答您的几个问题:

  

如果没有这个,它甚至被视为“跟踪”?

在这种情况下它不是 - 如果你的git配置中没有branch.bucket-4.mergebranch.bucket-4.remote,它就不会在任何意义上跟踪远程跟踪分支。 git remote show origin的输出只显示默认情况下推送分支的位置。

  

我是否可以添加一些配置,以便将来所有本地分支机构都能正确跟踪其遥控器?

我认为没有。当你在本地创建bucket-4时,正如我所假设的那样,远程跟踪分支不存在,所以它不能在那时设置 - 这将是非常混乱的默认行为。您只需要记住将-u添加到该分支的第一个git push到其上游存储库。

我希望能有所帮助。

至少从1.8.2.3(我的版本)开始,

git branch --set-upstream <branch> origin/<branch>已被弃用。

改为使用git branch --set-upstream-to=origin/<branch> <branch>
