Mod_wsgi and ticket #8365 (on trac.edgewall website) TROUBLE

[Tony]

Hello,

I have a windows 2003 server, its running apache 2.2 and python 2.6.2 and mod_wsgi. Trac 0.12dev was running ok on tracd but I had to change the genshi verssion on the file name as on the ticked I opened ticket #8365. When running the apache with wsgi web server trac sttoped working and only worked again when I changed the verssion on genshi package again to r0, but trac was not loading the pysql. It only loaded it when I placed a "import trac.db.pysql_backend" in my wsgi config file that is like this:

import os

os.environ['TRAC_ENV'] = '/usr/local/trac/mysite'
os.environ['PYTHON_EGG_CACHE'] = '/usr/local/trac/mysite/eggs'

import trac.web.main
import trac.db.pysql_backend
application = trac.web.main.dispatch_request

Now trac open but is now showing:

AttributeError: Cannot find an implementation of the "IRequestHandler" interface named "WikiModule". Please update the option trac.default_handler in trac.ini.

and when I try to log in:

Authentication information not available.

My authentication method is using the method described on ​http://trac.edgewall.org/wiki/TracStandalone using the trac-digest.py script to generate the passwords.

Any help will be appreciated.

Well, there's no such thing as:

import trac.db.pysql_backend

Start by fixing this, and see if the error persists.

Trac only works when I add the

import trac.db.pysql_backend

on my wsgi config.

If I remove it I get

Trac is configured in my httpd.conf file as follow:

NameVirtualHost *:80

    <VirtualHost *:80>
        ServerName www.trac.xxx.ba.gov.br
        ServerAlias *.trac.xxx.ba.gov.br
        ServerAdmin xxx@xxx.ba.gov.br
        WSGIScriptAlias / C:/TracProjects/SAS/conf/wsgiConfig.wsgi
        <Directory C:/TracProjects/SAS/conf>
            WSGIApplicationGroup %{GLOBAL}
            Order deny,allow
            Allow from all
        </Directory>
    </VirtualHost>
    
    <VirtualHost *:80>
        ServerName www.emarketing.xxx.ba.gov.br
        ServerAlias *.emarketing.xxx.ba.gov.br
        RewriteEngine On
        RewriteRule ^/(.*) \http://www.emarketing.xxx.ba.gov.br:8080/$1 [P]
    </VirtualHost>

Its weird. Trac worked ok running on tracd…

SORRY SORRY SORRY.

I gave the wrong command line I added in my wsgi config.

The correct import is:

import trac.db.sqlite_backend

This is what Im using just to make trac use sqlite. But there any still the issues I said before.
