python subprocess模块
Logintern09 人气:0使用python的subprocess模块实现对SVN的相关操作。
设置GitSvn类，在该类下自定义执行SVN常规操作的方法。
SVN的常规操作包括：
（1）获取SVN当前版本，通过方法get_version()实现；
（2）下载SVN指定仓库，通过方法download()实现，实际是通过调用SVN的命令行操作指令svn checkout实现的下载整个仓库功能；
（3）获取SVN某个仓库下的所有文件列表，通过方法search_dir()实现，实际是通过调用SVN的命令行操作指令svn list实现的获取仓库文件列表功能；
（4）在SVN指定位置创建新的文件夹，通过方法mkdir_command()实现，实际是通过调用SVN的命令行操作指令svn mkdir实现的创建文件夹或者目录功能；
（5）将本地仓库文件添加到SVN仓库，通过方法upload_file()实现，实际是通过调用SVN的命令行操作指令svn add实现的添加文件功能；
（6）将本地仓库已添加的文件提交SVN指定仓库，通过方法commit_command()实现，实际是通过调用SVN的命令行操作指令svn commit实现的提交文件功能；
（7）删除SVN仓库的目录，通过方法delete_url()实现，实际是通过调用SVN的命令行操作指令svn delete实现的删除目录功能；
（8）锁定SVN仓库的文件，通过方法lock_file()实现，实际是通过调用SVN的命令行操作指令svn lock实现的锁定文件功能；
（9）将SVN仓库的文件解除锁定，通过方法unlock_file()实现，实际是通过调用SVN的命令行操作指令svn unlock实现的解除文件锁定功能；
（10）查看SVN仓库文件当前状态，通过方法check_status()实现，实际是通过调用SVN的命令行操作指令svn status实现的查看文件状态功能；
（11）更新SVN仓库的某个文件，通过方法update_file()实现，实际是通过调用SVN的命令行操作指令svn up实现的更新文件功能；
GitSvn类定义如下：
