$ git clone <git-repo-url> --depth=1 repo
$ cd repo

现在浅克隆了一个git仓库repo。但仓库里查询远程分支只有一个默认分支（这里是 master ），没有其他分支（如 weekly ）：

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

查看git config：

$ git config --get remote.origin.fetch
+refs/heads/master:refs/remotes/origin/master

此时是无法拉取其他分支的。解决步骤如下：

$ git remote set-branches origin *

$ git config --get remote.origin.fetch
+refs/heads/*:refs/remotes/origin/*

$ git fetch --depth=1 origin weekly
remote: Enumerating objects: 31, done.
...
 * branch            weekly     -> FETCH_HEAD
 * [new branch]      weekly     -> origin/weekly

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

$ git checkout -b weekly origin/weekly
Switched to a new branch 'weekly'
branch 'weekly' set up to track 'origin/weekly'.

$ git branch -vv
  master 908e654 [origin/master] xxxx
* weekly 2b54b23 [origin/weekly] xxxx

搞定~
