wwl_private.conf文件用于存放默认的svn账号密码：(如果执行python的时候没有输入-u -p 脚本调用此私密配置)

#(username)
SVN_USERNAME=wwl
#(password)
SVN_PASSWORD=wwl

使用环境：python2.7、svn1.6、Ubuntu13.04

使用命令：python xxx.py -o "old_url" -n "new_url" -f y -u "name" -p "password"

脚本解析：使用svn info 命令判断url是否正确，svn用户名、密码是否正确；

　　　　   使用svn diff 对比2个svn-url输出结果到temp文件，然后解析temp文件；

              使用svn blame 判断文件是否是二进制文件；

              设置过滤器EXCLUDE，过滤指定文件不统计；

              过滤空行增删，不过滤注释。

弊端：svn diff 命令对一个代码行的修改算成+1行和-1行，此脚本没有另行统计修改的行数。

改进方案：使用svn diff --diff-cmd /usr/bin/diff 命令调用linux的diff来对比。linux的diff使用(a - 增)(c - 改)(d - 删)，比较方便分别计算增删改代码行，后期尝试修改。

 PS:如果使用的是svn1.7版本：检验svn用户名、密码和url替换成下面代码

#检验svn的用户名、密码和url是否正确
def svn_check_url_u_p(uname,pword,url,temp_svninfo):
    cmd = "svn info --no-auth-cache --non-interactive --username='%s' --password='%s' %s >%s" %(uname,pword,url,temp_svninfo)
    p = subprocess.Popen(cmd,shell=True,stdout=subprocess.PIPE,stderr=subprocess.PIPE)
    (stderr_test,stdout_test) = p.communicate()
    if len(stderr_test) == 0:
        print "url正确，svn账号密码正确:",url
    elif 'E170001' in stderr_test:
        print "svn账号密码不正确，请联系值班CM！！！"
        sys.exit(1) 
    elif 'E000002' in stderr_test:
        print "url错误，请检查配置:",url
        sys.exit(1)
