Git----分支管理之bug分支04
---恢复内容开始---
软件开发中,bug就像家常便饭一样,有了bug就需要修复,在Git中,由于分支是如此强大,所以,每个bug都可以通过一个临时分支来修复,修复后,合并分支,然后将临时分支删除。
当你接到一个修复一个代号101的bug任务时,很自然地,你想创建一个分支issue-101来修复它,但是,等等,当前正在dev上进行的工作还没有提交:
$ git status
On branch master
Your branch is up to date with 'origin/master'.
Changes to be committed:
(use "git reset HEAD <file>..." to unstage)
new file: hello.py
Changes not staged for commit:
(use "git add <file>..." to update what will be committed)
(use "git checkout -- <file>..." to discard changes in working directory)
modified: readme.txt
并不是你不想提交,而是工作只进行到一半,还没发提交,预计完成还需1天时间,但是,必须在两个小时之内修复该bug,怎么办?
幸好,Git还提供了一个stash功能,可以把当前工作现场“储藏”起来,等以后恢复现场后继续工作
$ git stash
Saved working directory and index state WIP on dev: 45e3302 add merge
现在,用git status查看工作区,就是干净的(除非有没有被Git管理的文件),因此可以放心的创建分支来修复bug。
$ git status
On branch dev
nothing to commit, working tree clean
首先确定要在哪个分支上修复bug,假定需要在master分支上修复,就从master创建临时分支:
$ git checkout master
Switched to branch 'master'
Your branch is up to date with 'origin/master'.
$ git checkout -b issue-101
Switched to a new branch 'issue-101'
现在修复bug,需要把readme.txt里面的内容“Git is software...”改为“Git is a free software....”然后提交
$ git add readme.txt
$ git commit -m "fix bug 101"
[issue-101 27c08c6] fix bug 101
1 file changed, 1 insertion(+), 1 deletion(-)
修复完成以后,切换到master分支,并合并完成,最后删除issue-101
$ git checkout master
Switched to branch 'master'
Your branch is up to date with 'origin/master'.
$ git merge --no-ff -m "merged bug fix 101" issue-101
Merge made by the 'recursive' strategy.
readme.txt | 2 +-
1 file changed, 1 insertion(+), 1 deletion(-)
太棒了,原计划两个小时的bug修复只花了五分钟,现在,是时候接着回到dev分支干活了
$ git checkout dev
Switched to branch 'dev'
$ git status
On branch dev
nothing to commit, working tree clean
工作区是干净的,刚才的工作现场存到哪里去了?用git stash list命令看看:
$ git stash list
stash@{0}: WIP on dev: 45e3302 add merge
工作现场还在,Git把stash内容存到某个地方了,但是需要恢复一下,有两个办法:
一是用git stash apply恢复,但是恢复后,stash内容并不删除,你需要用git stash drop来删除;
另一种方式是用git stash pop,恢复的同时把stash内容也删了。
$ git stash pop
On branch dev
Changes to be committed:
(use "git reset HEAD <file>..." to unstage)
new file: hello.py
Changes not staged for commit:
(use "git add <file>..." to update what will be committed)
(use "git checkout -- <file>..." to discard changes in working directory)
modified: readme.txt
Dropped refs/stash@{0} (b0d65dce977ac8b90006982914b08c161363c942)
再用git stash list查看,就看不到任何stash内容了:
$ git stash list
你可以多次stash,恢复的时候,先用git stash list查看,然后恢复指定的stash,用命令:
$git stash apply stash@{0}
