git xxx

A successful Git branching model

the main branches

• master
• develop

git checkout -b myfeature develop
  --从develop分支新建分支myfeature  
git checkout develop
  -- 切换到分支develop

Creating a feature brach

一个新功能的出现，应该创建一个新功能分支，例如myfeature，在该分支上功能开发完毕之后，需要合并到develop上。

$ git checkout develop  
 Switched to branch 'develop'  
$ git merge --no-ff myfeature  
 Updating ea1b82a..05e9557
 (Summary of changes)
$ git branch -d myfeature
 Deleted branch myfeature (was 05e9557).
$ git push origin develop

• --no-ff 参数的作用，确保每次merge都是一次新的commit，避免一个必要的信息的丢失
  

creat a release branch

release 分支是从develop分支新建来的。新功能开发完毕之后，后续在release分支进入bug fixes阶段（这个阶段不应该给在develop上进行）。release分支一般伴随着版本号,如release-1.2

$ git checkout -b release-1.2 develop
 Switched to a new branch "release-1.2"
$ git commit -a -m "version number to 1.2"
 [release-1.2 74d9424] Bumped version number to 1.2
 1 files changed, 1 insertions(+), 1 deletions(-)

bug fixes结束之后，需要将代码merge到master和develop分支（master上每一次merge都是一个版本，伴随着tag）

$ git checkout master
 Switched to branch 'master'
$ git merge --no-ff release-1.2
 Merge made by recursive.
 (Summary of changes)
$ git tag -a 1.2

$ git checkout develop
 Switched to branch 'develop'
$ git merge --no-ff release-1.2
 Merge made by recursive.
 (Summary of changes)

creat a hotfix branch

hotfix分支来自于master分支.当线上环境有bug需要修复的时候，需要新建hotfix分支，用来修复bug，hotfix分支一般伴随着版本号，如hotfix-1.2.1。

$ git checkout -b hotfix-1.2.1 master
 Switched to a new branch "hotfix-1.2.1"
$ git commit -a -m "version number to 1.2.1"
 [hotfix-1.2.1 41e61bb] Bumped version number to 1.2.1
 1 files changed, 1 insertions(+), 1 deletions(-)

hotfix修完buf完毕之后，也需要将代码同步到master和develop分支。同release分支。

git 命令

• git branch -r
  查看远程分支
• git branch -a
  查看所有的分支，包括远程和本地分支，*表示当前分支

下面两条命令，表示在当前本地分支合并远程分支

• git merge origin/master
• git rebase origin/master
