1:写在前面
在工作中经常会有这样的场景,线上发现紧急bug,需要切换到master进行修复,然后上线,但是此时我们还在开发分支,且因为一些原因本地的修改还不能提交,此时呢,如果我们直接切换分支到master的话会将分支修改的内容自动合并到master,这并不是我们想要的效果,本文看下如何处理这种情况。
2:测试
E:\workspace-idea\testtag>git branch -vv
master a85d924 [origin/master] add aa txt
* testtag-v1-new-branch-local a85d924 [origin/testtag-v1-new-branch] add aa txt
可以看到本地分支和远程分支的对应关系,此时我们在本地分支testtag-v1-new-branch-local ,先看下当前文件的内容:
E:\workspace-idea\testtag>dir
驱动器 E 中的卷是 新加卷
卷的序列号是 96D4-0486
E:\workspace-idea\testtag 的目录
2021/12/12 周日 16:06 <DIR> .
2021/12/12 周日 16:06 <DIR> ..
2021/12/12 周日 16:06 8 aa.txt
2021/12/12 周日 16:06 10,356 LICENSE
2021/12/12 周日 16:06 987 README.en.md
2021/12/12 周日 16:06 1,351 README.md
4 个文件 12,702 字节
2 个目录 457,044,774,912 可用字节
假设我们修改aa.txt 增加内容巴拉巴拉喇叭喇叭 ,如下:
$ cat aa.txt
111111
巴拉巴拉喇叭喇叭
然后增加一个新文件滴滴滴.txt ,内容为滴滴滴 ,如下:
$ cat 滴滴滴.txt
滴滴滴
此时,遇到了线上问题,需要切换到主干进行修复,先看下此时分支的内容:
JHP+Administrator@jhp MINGW64 /e/workspace-idea/testtag (testtag-v1-new-branch-local)
$ ls
aa.txt LICENSE README.en.md README.md 滴滴滴.txt
$ git add 滴滴滴.txt
warning: LF will be replaced by CRLF in 滴滴滴.txt.
The file will have its original line endings in your working directory
$ git status
On branch testtag-v1-new-branch-local
Your branch is up to date with 'origin/testtag-v1-new-branch'.
Changes to be committed:
(use "git restore --staged <file>..." to unstage)
new file: "\346\273\264\346\273\264\346\273\264.txt"
Changes not staged for commit:
(use "git add <file>..." to update what will be committed)
(use "git restore <file>..." to discard changes in working directory)
modified: aa.txt
在开发分支执行暂存--该操作很关键 ,如下:
$ git stash
Saved working directory and index state WIP on testtag-v1-new-branch-local: a85d924 add aa txt
JHP+Administrator@jhp MINGW64 /e/workspace-idea/testtag (testtag-v1-new-branch-local)
$ git stash show
aa.txt | 1 +
"\346\273\264\346\273\264\346\273\264.txt" | 1 +
2 files changed, 2 insertions(+)
此时我们已经将分支的修改暂存了,然后切换到主干修改紧急bug:
$ git checkout master
Switched to branch 'master'
Your branch is up to date with 'origin/master'.
JHP+Administrator@jhp MINGW64 /e/workspace-idea/testtag (master)
$ ls
aa.txt LICENSE README.en.md README.md
JHP+Administrator@jhp MINGW64 /e/workspace-idea/testtag (master)
$ cat aa.txt
111111
可以看到此时主干完全没有受到分支修改的影响,此时我们在主干修改bug,比如在aa.txt增加内容门店端的非跨组织流程收不到代办,需要周末加班处理 ,如下:
$ cat aa.txt
111111
门店端的非跨组织流程收不到代办,需要周末加班处理
好的,紧急bug修复完毕了,就push:
JHP+Administrator@jhp MINGW64 /e/workspace-idea/testtag (master)
$ git commit -am'门店端的非跨组织流程收不到代办,需要周末加班处理'
[master 57b8095] 门店端的非跨组织流程收不到代办,需要周末加班处理
1 file changed, 1 insertion(+)

a85d924..57b8095 master -> master
接下来就上线就行了,然后我们就可以切回到分支继续之前的开发了。
$ git checkout testtag-v1-new-branch-local
Switched to branch 'testtag-v1-new-branch-local'
Your branch is up to date with 'origin/testtag-v1-new-branch'.
JHP+Administrator@jhp MINGW64 /e/workspace-idea/testtag (testtag-v1-new-branch-local)
$ ls
aa.txt LICENSE README.en.md README.md
JHP+Administrator@jhp MINGW64 /e/workspace-idea/testtag (testtag-v1-new-branch-local)
$ cat aa.txt
111111
切换分支后可以看到之前修改的内容并没有恢复,这是因为我们已经暂存了,接下来弹出暂存的内容:
$ git stash pop
On branch testtag-v1-new-branch-local
Your branch is up to date with 'origin/testtag-v1-new-branch'.
Changes to be committed:
(use "git restore --staged <file>..." to unstage)
new file: "\346\273\264\346\273\264\346\273\264.txt"
Changes not staged for commit:
(use "git add <file>..." to update what will be committed)
(use "git restore <file>..." to discard changes in working directory)
modified: aa.txt
Dropped refs/stash@{0} (1fee21c566eb75f8c695247ffe691c8c68bf5c9d)
然后在查看,修改的内容就回来了:
$ ls
aa.txt LICENSE README.en.md README.md 滴滴滴.txt
JHP+Administrator@jhp MINGW64 /e/workspace-idea/testtag (testtag-v1-new-branch-local)
$ cat aa.txt
111111
巴拉巴拉喇叭喇叭
JHP+Administrator@jhp MINGW64 /e/workspace-idea/testtag (testtag-v1-new-branch-local)
$ cat 滴滴滴.txt
滴滴滴
接下里就可以继续愉快地写bug了。
