git“ - track”的区别是什么？和“设置 - 上游到”？ [英] What's the difference between git "--track" and "--set-upstream-to"?

问题描述

正如我所看到的，git - track 和 - set-upstream-to 修改了一个分支所以它成了一个跟踪（或上游）分支。但我无法理解的细微差别在哪里。 - track 记录remote branch tracks local：

  $ git checkout foo -b 
 $ git branch --track origin / retarget 
 
设置追踪本地分支foo的分支源/重定目标。 
 
 $ cat .git / config 
 [branchorigin / retarget] 
 remote =。 
 merge = refs / heads / foo 
  

- set -upstream-to 记录本地分支跟踪远程分支：

  $ git checkout foo -b 
 $ git branch --set-upstream-to origin / retarget 
 
设置分支foo以追踪远程分支从原点返回的目标。 
 
 $ cat .git / config 
 [branchfoo] 
 remote = origin 
 merge = refs / heads / retarget 
  

这两者有什么区别？我确信跟踪分支是一个简单的概念，在分支中跟踪头部指定分支位置的额外上游指针在远程存储库中。但似乎更复杂？

解决方案

  $ git checkout foo -b 
 $ git branch --track origin / retarget 
  

前两个命令指示git：

• 创建一个名为 origin / retarget 的本地分支（非常糟糕的想法，因为它是命名为远程跟踪分支，而它实际上是一个简单的本地分支，其名称中包含 / '）


• 开始从当前分支（ foo ，另一个本地分支）


• 使新的本地分支跟踪其起始点。 li>
  

请参阅 git branch

   - 曲目
  

创建新分支时，设置分支。< name> .remote 和分支。< name> .merge 配置条目

当你从一个分支开始创建一个分支时，你会使用跟踪远程跟踪一个。

换句话说，你的第一个例子不是你将如何使用 - track 。

这会更好：

  git checkout -b foo --track origin / retarget

至于之间的区别 - track 和 - set-upstream-to ：

   -  set-upstream-to 
  




如果指定分支还没有存在，或者如果 - force 已被给出，其行为与 - track 完全相同。

除非分支指向的地方没有改变，否则在创建分支时 设置配置，如 - track 。 >

As I can see, both git --track and --set-upstream-to modify a branch so it becames a tracking (or upstream) branch. But where is a subtle difference I can't comprehend. The --track records "remote branch tracks local":

$ git checkout foo -b
$ git branch --track origin/retarget

Branch origin/retarget set up to track local branch foo.

$ cat .git/config
[branch "origin/retarget"]
        remote = .
        merge = refs/heads/foo

While --set-upstream-to records "local branch tracks remote branch":

$ git checkout foo -b
$ git branch --set-upstream-to origin/retarget

Branch foo set up to track remote branch retarget from origin.

$ cat .git/config
[branch "foo"]
        remote = origin
        merge = refs/heads/retarget

What's the difference between this two? I was sure that "tracking branch" is simple concept with additional upstream pointer inside branch that tracks head position of specified branch in remote repository. But seems it's much more complicated?

解决方案

$ git checkout foo -b
$ git branch --track origin/retarget

The first two commands instruct git to:

• create a local branch named "origin/retarget" (very bad idea, as it is named as a remote tracking branch", while it is actually a simple local branch with a '/' in its name)
• starting from the current branch ("foo", another local branch)
• to make that new local branch tracking its starting point.

See git branch

--track

When creating a new branch, set up branch.<name>.remote and branch.<name>.merge configuration entries to mark the start-point branch as "upstream" from the new branch.

You would use track when you create a branch starting from a remote tracking one.

In other word, your first example isn't how you would use --track.
This would work better:

git checkout -b foo --track origin/retarget

---

As for the difference between --track and --set-upstream-to:

--set-upstream-to

If specified branch does not exist yet or if --force has been given, acts exactly like --track.
Otherwise sets up configuration like --track would when creating the branch, except that where branch points to is not changed.
