Description

Just now upgraded to moin-1.3.3 and i am still getting the same error. I am using the following line in wikiconfig.py. Adding this line makes moin come up with the exception.

    url_mappings  = {"/cgi-bin/moin.cgi/":"/"}

Plain text traceback:

AttributeError: 'NoneType' object has no attribute 'startswith'

The cgitb output is more revealing. I am including here the part I couldnt understand:

[...]

Somehow line 862 of wikiutil.py is sending a valid URL to formatter.url, but the latter is not receiving any URL in its parameters.

Steps to reproduce

1. I am getting this on the site http://www.lug-delhi.org (you can take a look there to see if some combination of links out there is causing the problem).

2. I am getting this problem as soon as I add the following line in wikiconfig.py.

       url_mappings  = {"/cgi-bin/moin.cgi/":"/"}

Discussion

I am experiencing exactly the same bug with MoinMoin 1.3.3 and Python 2.2.2 on Linux.

I would like to use shorter urls, i.e. http://sitename/FrontPage instead of http://sitename/cgi-bin/moin.cgi/FrontPage, so I've added the necessary RewriteRule clauses to my .htaccess and now I would like MoinMoin to generate similar urls via url_mappings (is there a better way?), but url_mappings is causing this error.

I don't think you need this at all. You can define short urls by ScriptAlias or rewrite rules, as described in the installation docs. -- NirSoffer 2005-02-03 17:47:50

The patch fixes the traceback all right. I dont thing ScriptAlias or rewrite rules solves the complete problem. Incoming links can be routed to Moin using this all right. But the links that moin generates should also follow the url mapping that these rewrite rules provide.

Even now, URL mapping feature works partially. It doesnt work for URLs like the links, or the URLs in the titlepage. I dont want my users to bookmark pages with /cgi-bin/moin.cgi in them. I want them to use simple urls like http:/ /domain/PageName. But if moin doesnt cooperate sooner or later they will bookmark the ugly URLs instead.

• What do you mean by "It doesnt work for URLs like the links"? Sounds like "it does not really work". If that is true, reopen the bug.
  • No, do not open this bug as it is fixed and closed. This bug is about traceback while using url_mapping. If url_mapping is not working as described in the documentation, then open a new bug.

This has nothing to do with that specific fixed bug, so there is no point to discuss this here. As I said, you don't need url_mapping to get rid of cgi-bin/moin.cgi in urls. Please use the proper page, MoinMoinQuestions, or any Support* page to discuss your configuration difficulties. -- NirSoffer 2005-02-10 10:48:11
