python调用subprocess模块实现命令行操作控制SVN的方法

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;
