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 "url" -f y -u "name" -p "password"
背景说明:统计一个svn的url代码总行数其实也可以使用前面那个diff脚本,其中old_url设置为一个空url。
但是有2点不足:
1.svn diff只能在同一个物理库中进行,如果有多个物理库需要对应建多个空url;
2.如果url里面包含的代码非常多,使用diff脚本生成的temp文件将会很庞大,解析temp文件很慢甚至卡死。
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 list 输出此url包含的所有文件名到temp文件并排除以'/'结尾的文件夹;
使用svn blame 遍历所有文件并计算非空行数,排除二进制文件;
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;
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
1 #检验svn的用户名、密码和url是否正确 2 def svn_check_url_u_p(uname,pword,url,temp_svninfo): 3 cmd = "svn info --no-auth-cache --non-interactive --username='%s' --password='%s' %s >%s" %(uname,pword,url,temp_svninfo) 4 p = subprocess.Popen(cmd,shell=True,stdout=subprocess.PIPE,stderr=subprocess.PIPE) 5 (stderr_test,stdout_test) = p.communicate() 6 if len(stderr_test) == 0: 7 print "url正确,svn账号密码正确:",url 8 elif 'E170001' in stderr_test: 9 print "svn账号密码不正确,请联系值班CM!!!" 10 sys.exit(1) 11 elif 'E000002' in stderr_test: 12 print "url错误,请检查配置:",url 13 sys.exit(1)
