User Name policy configurable?

[anonymous]

It seems it is hard coded the username policy. I think it would be nice if it could be configured in the trac.ini file.

Example, I don't want the minimum of 5 chars long user names. I found the code, but I don't know python. register.py:

username_regexp = Option('account-manager', 'username_regexp',
        r'(?i)^[A-Z0-9.\-_]{5,}$',
        doc="A validation regular expression describing new usernames.")

couldn't it be laoded from the inii file like:

 def validate_registration(self, req):
        acctmgr = AccountManager(self.env)

        """ New """
        regexp = req.args.get('username.regexp', '');
        if regexp=""
                username_regexp = Option('account-manager', 'username_regexp',
                        r'(?i)^[A-Z0-9.\-_]{5,}$',
                        doc="A validation regular expression describing new usernames.")
        else:
                username_regexp = Option('account-manager', 'username_regexp',
                        regexp, """ Notice I dont know how to handle the r'...' """
                        doc="A validation regular expression describing new usernames.")

        """ End new

        username = acctmgr.handle_username_casing(
            req.args.get('username', '').strip())
        if self.username_regexp != "" and \
                not re.match(self.username_regexp.strip(), username):
            raise RegistrationError(N_(
                "Username %s doesn't match local naming policy."),
                tag.b(username)
            )

...

Of course cleaning up constants and so on.
