SVN与ReviewBoard联动（1）

公司的SVN服务器是在Windows上的，ReviewBoard是在Linux虚拟服务器上的。
好吧，主要是历史原因了哦。。。

解决思路是，利用SVN的post-commit钩子，在提交后，将版本号存到一个文件中。
在Linux服务器中，定时去扫描这些文件，有变动的话，则利用RBTools提交请求。

1、Windows中用post-commit钩子获取版本号
post-commit.bat

@echo off
SET REPOS=%1%
SET REV=%2%
SET RPATH=PATH_TO_STORE_FILE

CALL :getfilename %REPOS%

echo %REV% >> %RPATH%\%FNAME%.txt

:success
exit 0

:getfilename
set FNAME=%~nx1

2、Linux中用python脚本扫描文件变动
runme.py

#!/usr/bin/python
# -*- coding: utf-8 -*-

遍历监视文件夹下所有的txt文件
当文件多余两行时，对于每一行，调用rbt生成review请求
最后，只保留最后一行

        return 'no svn commiter'

#start here
#get_svn_log('193')
#get_svn_commiter('193')

3、建立定时任务，执行脚本

crontab -l

#半小时运行一次
*/30 * * * * /home/neohope/scripts/runme.py

比较麻烦的是，仍需要在Linux下面，先把SVN的repository检出才可以。
同时要注意，要做好SVN及ReviewBoard之间名称的映射。。。
