GIT学习----第十四节：BUG分支

学习目的

遇到临时bug需要紧急修复，在git如何处理？
git如何进行工作区进行储藏，等待bug修复后的工作区恢复？

临时储藏

修改后查看工作区状态

$ git status
On branch master
Your branch is ahead of 'origin/master' by 10 commits.
  (use "git push" to publish your local commits)

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

no changes added to commit (use "git add" and/or "git commit -a")

临时存储git stash

$ git stash
Saved working directory and index state WIP on master: 118be5d --no-ff模式合并

查看工作区

$ git status
On branch master
Your branch is ahead of 'origin/master' by 10 commits.
  (use "git push" to publish your local commits)

nothing to commit, working tree clean

新建bug分支’issue-001’

$ git checkout -b issue-001
Switched to a new branch 'issue-001'

修改文件查看，添加’bug分支测试！’

$ cat readme.txt
Git is a version control system.
Git is free software.
Git is a distributed version control system.
Git is free software.
添加一行测试工作区、暂存区、分支。
cat 命令测试。
测试修改文件后各区状态！
测试git diff，查看工作区和分支文件的修改情况！
再次测试git diff对比工作区和版本库最新版本的区别。
测试撤销修改！
Creating a new branch is quick and simple.
测试分支合并冲突！

分支管理测试！

测试fast forward合并模式！

测试--no-ff合并模式！

bug分支测试！

bug分支提交

$ git add readme.txt

$ git commit -m "bug分支测试提交"
[issue-001 991a531] bug分支测试提交
 1 file changed, 3 insertions(+), 1 deletion(-)

切换到master分支，合并issue-001分支，删除issue-001分支

$ git checkout master
Switched to branch 'master'
Your branch is ahead of 'origin/master' by 10 commits.
  (use "git push" to publish your local commits)


$ git merge --no-ff -m "bug分支测试合并" issue-001
Merge made by the 'recursive' strategy.
 readme.txt | 4 +++-
 1 file changed, 3 insertions(+), 1 deletion(-)


$ git branch -d issue-001
Deleted branch issue-001 (was 991a531).

查看工作区，查看现场储藏区，恢复储藏文件，再查看工作区

查看工作区
$ git status
On branch master
Your branch is ahead of 'origin/master' by 12 commits.
  (use "git push" to publish your local commits)

nothing to commit, working tree clean

查看现场储藏区
$ git stash list
stash@{0}: WIP on master: 118be5d --no-ff模式合并

恢复储藏文件
$ git stash pop
Auto-merging readme.txt
CONFLICT (content): Merge conflict in readme.txt

再查看工作区
$ git status
On branch master
Your branch is ahead of 'origin/master' by 12 commits.
  (use "git push" to publish your local commits)

Unmerged paths:
  (use "git reset HEAD <file>..." to unstage)
  (use "git add <file>..." to mark resolution)

        both modified:   readme.txt

no changes added to commit (use "git add" and/or "git commit -a")

总结

正在工作区工作，突然进行紧急bug修复，储藏现场git stash；
新建bug分支，进行修复bug，提交修复，切换到master，合并bug分支，删除bug分支。
恢复工作区git stash pop(简写命令)。查看储藏列表git stash list；恢复储藏git stash apply；删除储藏git stash drop。
