svn分支管理进行迭代开发

[root@ok svndata]# svn co svn://192.168.1.111/app01
＃ checkout项目到本机

开始规划我们的svn项目目录：

[root@ok svndata]# tree app01/　
app01/　＃项目根目录
├── branches　＃其他分支
│   ├── iterative-2　＃迭代分支
│   ├── iterative-2-feature1　＃基于迭代分支的特性１分支
│   └── iterative-2-feature2    ＃基于迭代分支的特性２分支
├── tags
└── trunk　＃主干分支

6 directories, 0 files

主干分支上创建第一个代码文件：

[root@ok app01]# svn mkdir trunk
A         trunk
[root@ok app01]# touch trunk/hello.py    
[root@ok app01]# svn add trunk/hello.py 
A         trunk/hello.py
[root@ok app01]# svn ci -m "init"
Adding         trunk
Adding         trunk/hello.py
Transmitting file data .
Committed revision 7.
[root@ok app01]# svn update
At revision 7.

首先创建分支目录：

[root@ok app01]# svn mkdir branches
A         branches
[root@ok app01]# svn ci -m "创建分支目录"
Adding         branches

Committed revision 8.
[root@ok app01]# svn update
At revision 8.

创建分支的方式一：

[root@ok app01]# svn cp trunk/ branches/iterative-2
A         branches/iterative-2
[root@ok app01]# svn ci -m "创建二期迭代分支"
Adding         branches/iterative-2

Committed revision 9.

创建分分支的方式二：

[root@ok app01]# svn cp svn://192.168.1.111/app01/trunk \
> svn://192.168.1.111/app01/branches/iterative-2 \
> -m "创建二期迭代分支"

注意一定要svn update 否则可能会看不到更新log
[root@ok app01]# svn update

[root@ok app01]# svn log -v

r11 | svnroot | 2016-08-26 12:22:45 +0800 (Fri, 26 Aug 2016) | 1 line
Changed paths:
   A /branches/iterative-2 (from /trunk:8)

创建二期迭代分支

基于迭代分支创建特性分支：
因为一次迭代开发可能包含很多新功能，面这些个功能可以由Ｎ个开发人员来并行开发。所以最佳方案是每个功能点再建一个分支出来，实现之后再合并回二期迭代分支。

[root@ok app01]# svn cp svn://192.168.1.111/app01/branches/iterative-2 \
> svn://192.168.1.111/app01/branches/iterative-2-feature-say-hi \
> -m "2期需求:say hi功能"

Committed revision 12.
[root@ok app01]# svn update
A    branches/iterative-2-feature-say-hi
A    branches/iterative-2-feature-say-hi/hello.py
Updated to revision 12.
[root@ok app01]# svn ci -m "2期需求:say hi功能"
[root@ok app01]# svn update

[root@ok app01]# svn log -v

实现特性功能：

[root@ok app01]# echo "加入代码实现一些功能！！！">branches/iterative-2-feature-say-hi/hello.py 
[root@ok app01]# svn commit -m "say hi 功能"

创建二期迭代分支

合并回迭代分支

[root@ok app01]# svn mkdir branches/{iterative-2-feature1,iterative-2-feature2}
A         branches/iterative-2-feature1
A         branches/iterative-2-feature2
[root@ok app01]# svn ci -m "基于迭代分支的特性1和2分支"

使用reintegrate合并后，迭代分支并没有保存特　性分支的提交历史（但是在branches目录下，能看到完整的提交历史）

迭代分支合并到 trunk 中

[root@ok trunk]# svn merge --reintegrate svn://192.168.1.111/app01/branches/iterative-2

删除特性分支

[root@ok iterative-2]# svn rm svn://192.168.1.111/app01/branches/iterative-2-feature-say-hi -m ""

[root@ok app01]# svn mkdir tags

创建分支：

[root@ok branches]# svn cp -m "create branch" svn://192.168.1.111/app01/trunk svn://192.168.1.111/app01/branches/br_feature001

获得分支：

[root@ok branches]# svn co svn://192.168.1.111/app01/branches/br_feature001
A    br_feature001/hello.py
Checked out revision 17.

合并主干上的最新代码到分支上

[root@ok br_feature001]# svn merge svn://192.168.1.111/app01/trunk

测试如下：

[root@ok br_feature001]# cat hello.py 
[root@ok br_feature001]# svn merge svn://192.168.1.111/app01/trunk
--- Merging r18 into '.':
U    hello.py 
[root@ok br_feature001]# cat hello.py 
12k

如果需要预览该刷新操做，可以使用svn mergeinfo:

[root@ok trunk]# svn mergeinfo svn://192.168.1.111/app01/trunk --show-revs eligible
r18

在分支上的开发结束，分支上的代码需要合并到主干，如下步骤:

[root@ok br_feature001]# cat hello.py 
12k
[root@ok br_feature001]# svn status
 M      .
M       hello.py
#末把分支合并到主干之前，查看代码：
[root@ok br_feature001]# cat ../../trunk/hello.py 
12k
[root@ok trunk]# cat hello.py 
12k
更新主干内容！！！
[root@ok trunk]# svn merge --reintegrate svn://192.168.1.111/app01/branches/br_feature001

分支合并到主干中完成后应当删该分支，因为在svn中该分支已经不能进行刷新也不能合并到主干。

[root@ok trunk]# svn log

init
------------------------------------------------------------------------
[root@ok trunk]# svn -r 18:19 merge svn://192.168.1.111/app01/trunk

建立tags

产品开发已经基本完成，并且通过很严格的测试，这时候我们就想发布给客户使用，发布为1.0版本

[root@ok app01]# svn copy svn://192.168.1.111/app01/trunk svn://192.168.1.111/app01/1.0 -m "Release 1.0"

Committed revision 20.

可以看出，就是简单的复制动做。
