git stash封存分支 以及关于开发新功能的处理

有种情况，我们要修复项目的bug时，但别的分支有修改的代码，要修复的bug可能会影响（所有分支共用一个暂存区）。可以单独创建一个bug分支，用于修复和提交bug，在修改前可以先stash封存分支修改的代码。

测试，首先在slave分支里修改文件：456的内容，然后执行git stash 封存slave分支未提交的代码。

laoni@DESKTOP-TPPLHIB MINGW64 /c/laoni/PycharmProjects/github_test (master)
$ git checkout slave
Switched to branch 'slave'

laoni@DESKTOP-TPPLHIB MINGW64 /c/laoni/PycharmProjects/github_test (slave)
$ git status
On branch slave
nothing to commit, working tree clean

laoni@DESKTOP-TPPLHIB MINGW64 /c/laoni/PycharmProjects/github_test (slave)
$ ls

$ cat 456

laoni@DESKTOP-TPPLHIB MINGW64 /c/laoni/PycharmProjects/github_test (slave)
$ vim 456

laoni@DESKTOP-TPPLHIB MINGW64 /c/laoni/PycharmProjects/github_test (slave)
$ cat 456
修改456文件

laoni@DESKTOP-TPPLHIB MINGW64 /c/laoni/PycharmProjects/github_test (slave)
$ git stash
warning: LF will be replaced by CRLF in 456.
The file will have its original line endings in your working directory.

创建bug01分支，并修复和提交bug文件：998，然后切换到master分支，合并bug01分支

$ git branch bug01

laoni@DESKTOP-TPPLHIB MINGW64 /c/laoni/PycharmProjects/github_test (slave)
$ git branch
  bug01
  master
* slave

laoni@DESKTOP-TPPLHIB MINGW64 /c/laoni/PycharmProjects/github_test (slave)
$ git checkout bug01
Switched to branch 'bug01'

laoni@DESKTOP-TPPLHIB MINGW64 /c/laoni/PycharmProjects/github_test (bug01)
$ vim 998

laoni@DESKTOP-TPPLHIB MINGW64 /c/laoni/PycharmProjects/github_test (bug01)
$ cat 998

$ git status

最后再解封slave,使用git stash pop可以解封最近的一次封存，使用git stash apply 封存编号可以解封指定的封存位置。
