技术生活杂烩-迟到的博客
一。使用场景: 本地新建一个分支后，必须要做远程分支关联。如果没有关联，git会在下面的操作中提示你显示的添加关联。关联目的是如果在本地分支下操作： git pull, git push ，不需要指定在命令行指定远程的分支． I create a new branch in Git:git branch my_branch
Push it:
git push origin my_branch
Now say someone made some changes on the server and I want to pull from origin/my_branch. I do:
git pull
But I get:
You asked me to pull without telling me which branch you
want to merge with, and 'branch.my_branch.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:
remote = <nickname>
merge = <remote-ref>
url = <url>
fetch = <refspec>
See git-config(1) for details.
I learned that I can make it work with:
git branch --set-upstream my_branch origin/my_branch
注意，推送到远程分支后，默认也不是跟踪snsconnct:mater分支，你只要没有显示指定，git pull的时候，就会提示你。
二。替代：
该语法等价与在第一次提交分支时，使用git push -u origin my_branch：
一种更简单的方式用来取代不好忘记的 git branch --set-upstream 是git push -u origin my_branch
在你第一次提交你的分支的时候使用。它会像git branch --set-upstream一样在本地分支与远程分去建立联系。
通常我们在新建分支的时候，一定要显式建立这种联系。
三。类似
thisbe equivalent to what is automatically done when you initially clone a repository
附：
下面部分就是git clone之后，添加到文件里的内容。感觉git clone主要是cline仓库。用来初始化。所以，它不能取代--set-upstream.
repositoryformatversion = 0
filemode = true
logallrefupdates = true
autocrlf = false
bare = false
url = ssh://root@hostname/path
fetch = +refs/heads/*:refs/remotes/origin/*
remote = origin
merge = refs/heads/sns
或者
# git remote add origin ssh://...
now configure master to know to track
# git config branch.master.remote origin
# git config branch.master.merge refs/heads/master
and push
# git push origin master
四。命令的最终修改都是针对config文件。
使用－－set-upstream去跟踪远程分支。
config在命令执行之前：
repositoryformatversion = 0
filemode = true
bare = false
logallrefupdates = true
ignorecase = true
fetch = +refs/heads/*:refs/remotes/origin/*
url = root@****************
remote = origin
merge = refs/heads/master
url = root@app220:/*******************
fetch = +refs/heads/*:refs/remotes/snsconnect/*
执行之后：
remote = snsconnect
merge = refs/heads/sns
