因为在trac中只能使用trac-admin命令一个个提交权限，很麻烦，所以就想写一个脚本来搞定它，如果是在以前，我就会用shell来做，现在我想用python来锻练一下：

trac-access-file content as follow:
permission_all = BROWSER_VIEW,CHANGESET_VIEW,CONFIG_VIEW,FILE_VIEW,LOG_VIEW,MILESTONE_ADMIN,MILESTONE_CREATE,MILESTONE_DELETE,MILESTONE_MODIFY,MILESTONE_VIEW,REPORT_ADMIN,REPORT_CREATE,REPORT_DELETE,REPORT_MODIFY,REPORT_SQL_VIEW,REPORT_VIEW,ROADMAP_ADMIN,ROADMAP_VIEW,SEARCH_VIEW,TICKET_ADMIN,TICKET_APPEND,TICKET_CHGPROP,TICKET_CREATE,TICKET_MODIFY,TICKET_VIEW,TIMELINE_VIEW,TRAC_ADMIN,WIKI_ADMIN,WIKI_CREATE,WIKI_DELETE,WIKI_MODIFY,WIKI_VIEW
 
team_all = alexxu,arielgu,ericgao,geminisshao,thunderzhang,junzhao,rogersong,johnshen,jackytian,sanzhong,yitangcheng
 
permission_allow = BROWSER_VIEW,LOG_VIEW,FILE_VIEW,CHANGESET_VIEW,TICKET_VIEW,MILESTONE_VIEW,ROADMAP_VIEW,REPORT_VIEW,WIKI_VIEW,TIMELINE_VIEW,SEARCH_VIEW
 
 
我已经编写了一个脚本permission.py：

#!/usr/bin/python
import os
f = open("/etc/apache2/trac-access-file","r");
str = f.read()
for line in str.split('\n'):
        if line == '':
                continue

        elif line[0:8] == 'team_all':
                for unit in line[11:].split(','):
                        command= "trac-admin /var/trac permission add %s team_all anonymous " %(unit)
                        if os.system(command) == 0:
                                print command,' Success'
                        else:
                                print command,'Failed'
                continue

        elif line[0:16] == 'permission_allow':
                for unit in line[19:].split(','):
                        command= "trac-admin /var/trac permission add team_all %s" %(unit)
                        command2= "trac-admin /var/trac permission add anonymous %s" %(unit)
                        if os.system(command) == 0 or os.system(command2)==0:
                                print command,' Success'
                        else:
                                print command,'Failed'
                continue

        elif line[0:14] == 'permission_all':
                for unit in line[17:].split(','):
                        command= "trac-admin /var/trac permission remove anonymous %s" %(unit)
                        if os.system(command) == 0:
                                print command,' Success'
                        else:
                                print command,'Failed'
                continue

我这个脚本只能算个简单的工作脚本而已，肯定会有高人能提出改进的意见，请不吝赐教，给思路也行。谢谢

不错。就是取名字的时候你使用定长。比较好的方式是使用splite('=',
1)来处理，这样按=进行拆分。然后再去掉首尾空格就好了。使用定长的话一旦前面的串名发生变化，改动就比较多，而且不通用。

另外权限可以与用户分开，这样互不影响。另外还可以有两种工作模式，一种是预设好的，即有哪些组，有哪些权限。一种是运行后再修改，这样可以提供一个交互环境。
