'git remote show'的详细解释

Question

老实说,找不到任何详细的输出文档git remote show(当然不在手册页上)

特别是,Local可以理解这些部分的清晰,准确的解释.

我发现令人困惑的一个例子:

这里我有两个遥控器,klas和origin以及它们产生的输出:

> git remote show klas
* remote klas
  Fetch URL: ..\klasrepo
  Push  URL: ..\klasrepo
  HEAD branch: master
  Remote branches:
    experiment  tracked
    feature     tracked
    master      tracked
    pu          tracked
    stashbranch tracked
  Local branch configured for 'git pull':
    pu merges with remote pu
  Local refs configured for 'git push':
    experiment pushes to experiment (fast-forwardable)
    feature    pushes to feature    (fast-forwardable)
    master     pushes to master     (fast-forwardable)
    pu         pushes to pu         (up to date)
> git remote show origin
* remote origin
  Fetch URL: C:/Temp/git/.\barerepo.git
  Push  URL: C:/Temp/git/.\barerepo.git
  HEAD branch: experiment
  Remote branches:
    experiment tracked
    master     tracked
  Local branches configured for 'git pull':
    experiment  merges with remote experiment
    master     rebases onto remote master
  Local refs configured for 'git push':
    experiment pushes to experiment (up to date)
    master     pushes to master     (fast-forwardable)

请注意,两者都列出了实验和主数据.那是什么意思？我已经配置了master和experiment来分别跟踪origin/master和origin/experiment(和pu来跟踪klas/pu). local refs configured for 'git push'

我的本地功能分支没有设置为跟踪任何内容,但仍然列在local refs configured for 'git push'(唯一的连接似乎是相同的名称,另一个非跟踪分支,foo,未提及).git push虽然在功能给予fatal: The current branch feature has no upstream branch.- 几乎"快速转发".

似乎列出的本地分支的标准local refs configured for 'git push'是,恰好存在一个具有相同名称的远程分支？

以供参考:

Answer 1

这似乎是 Git 1.8.1 中的一个错误。

浏览 Git 源代码（特别是remote.c和builtin/remote.c），“为‘git Push’配置的本地引用”下的列表计算如下：

1. 收集配置的推送参考规范：
   • 读取.git/remotes/<remotename>（过时的配置文件；请参阅git help repository-layout）
   • 读取.git/branches/<branchname>（另一个过时的配置文件）
   • 检查remote.<remotename>.push配置项
2. 如果步骤 #1 没有找到任何内容，则用作:唯一的推送 refspec
3. 查找与收集的推送引用规范匹配的所有{本地，远程}分支组合

请注意，上述算法不关注branch.<branchname>.remote、branch.<branchname>.merge或push.default。

在典型的使用模式下，上述算法中的步骤 #1 将永远不会找到任何配置的 refspec，因此:将被使用。该 refspec 是一个简单的匹配 refspec，因此在典型用法中，如果本地和远程存储库中都有指定的分支，则git remote show <remotename>始终会打印。<branchname> pushes to <branchname><branchname>
