与远程同名的Git分支以不同方式创建

Question

创建名称与远程分支名称匹配的分支时,push和pull的配置设置不同.

拥有当前的远程分支:

$ git branch -r
  origin/HEAD -> origin/master
  origin/master
  origin/someBranch

并创建一些跟踪远程分支的本地分支:

$ git branch someBranch origin/someBranch 
  Branch someBranch set up to track remote branch someBranch from origin.
$ git branch someOtherBranch origin/someBranch 
  Branch someOtherBranch set up to track remote branch someBranch from origin.

检查跟踪和上游信息:

$ git remote show origin
* remote origin
  Fetch URL: git@github.somewhere.com:maic/repo.git
  Push  URL: git@github.somewhere.com:maic/repo.git
  HEAD branch: master
  Remote branches:
    master     tracked
    someBranch tracked
  Local branches configured for 'git pull':
    master          merges with remote master
    someBranch      merges with remote someBranch
    someOtherBranch merges with remote someBranch
  Local refs configured for 'git push':
    master     pushes to master     (up to date)
    someBranch pushes to someBranch (up to date)

为什么没有推送配置创建第二个分支？

Answer 1

如果本地和远程分支具有相同的名称,则本地分支只能跟踪远程分支以进行推送.为了提取,本地分支不需要与远程分支具有相同的名称.有趣的是,如果你设置一个分支"富"跟踪远程分支"原产地/条"(与"git的分支富产地/条"),如果远程仓库不现在有一个分支命名为"富",那么如果以后遥控器确实得到一个名为foo的分支,然后本地分支foo将跟踪origin/foo!

$ git clone dev1 dev2
Cloning into 'dev2'...
done.
$ cd dev2
#
# After clone, local master tracks remote master.
#
$ git remote show origin
* remote origin
Fetch URL: /Users/ebg/dev1
Push  URL: /Users/ebg/dev1
HEAD branch: master
Remote branch:
  master 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)
#
# Create branch br1 to track origin/master
#
$ git branch br1 origin/master
Branch br1 set up to track remote branch master from origin.
#
# br1 tracks origin/master for pulling, not pushing
#
$ git remote show origin
* remote origin
Fetch URL: /Users/ebg/dev1
Push  URL: /Users/ebg/dev1
HEAD branch: master
Remote branch:
  master tracked
Local branches configured for 'git pull':
  br1    merges with remote master
  master merges with remote master
Local ref configured for 'git push':
  master pushes to master (up to date)
#
# Go to the origin repo and now create a new 'br1' branch
#
$ cd ../dev1
$ git checkout -b br1
Switched to a new branch 'br1'
#
# Go back to dev2, fetch origin
#
$ cd ../dev2
$ git fetch origin
From /Users/ebg/dev1
 * [new branch]      br1        -> origin/br1
#
# Now local branch 'br1' is tracking origin/br1 for pushing
#
$ git remote show origin
* remote origin
Fetch URL: /Users/ebg/dev1
Push  URL: /Users/ebg/dev1
HEAD branch (remote HEAD is ambiguous, may be one of the following):
  br1
 master
Remote branches:
  br1    tracked
  master tracked
Local branches configured for 'git pull':
  br1    merges with remote master
  master merges with remote master
Local refs configured for 'git push':
  br1    pushes to br1    (up to date)
  master pushes to master (up to date)

所以br1原本应该从主人那里拉/推,我们最终会从原点/主人那里拉出br1并推到我们从未知道的分支.
