Trac-Bzr

Can't synchronize with repository "(default)" (Unsupported version control system "bzr"...

Asked by Brian Cox

Hello,

I'm trying to get TracBzr working on my Ubuntu 9.10 machine.

I have gone through the steps here:
http://trac.edgewall.org/wiki/Ubuntu-10.04-Bazaar

But I get this error within Trac:
Warning: Can't synchronize with repository "(default)" (Unsupported version control system "bzr": Can't find an appropriate component, maybe the corresponding plugin was not enabled? ). Look in the Trac log for more information.

I don't see anything in the log though, unless I am looking in the wrong place...

Any ideas on what could be causing this error?

my /etc/apache2/conf.d/trac.GDB.conf looks like:
WSGIScriptAlias /trac /var/tracprojects/GDB/deploy/cgi-bin/trac.wsgi

    <Directory /var/tracprojects/GDB/deploy/cgi-bin>
     WSGIApplicationGroup %{GLOBAL}
     Order deny,allow
     Allow from all
    </Directory>

    <Location "/trac/login">
     AuthType Basic
     AuthName "Trac"
     AuthUserFile /var/tracprojects/.htpasswd
     Require valid-user
    </Location>

 WSGIScriptAliasMatch ^/trunk/.*/\.bzr/smart$ /var/tracprojects/GDB/deploy/cgi-bin/bzr.wsgi

     #The three next lines allow regular GETs to work too
     RewriteEngine On
     RewriteCond %{REQUEST_URI} !^/trunk/.*/\.bzr/smart$
     RewriteRule ^/trunk/(.*/\.bzr/.*)$ /mnt/bazaar/trunk/$1 [L]

    <Directory /mnt/bazaar/trunk/>
     WSGIApplicationGroup %{GLOBAL}
    </Directory>

    <Location /trunk/>
     AuthType Basic
     AuthName "Trac Source Access"
     AuthUserFile /var/tracprojects/.htpasswd
    <LimitExcept GET>
        Require valid-user
    </LimitExcept>
    </Location>

my /var/tracprojects/GDB/deploy/cgi-bin/bzr.wsgi file looks like:
from bzrlib.transport.http import wsgi

def application(environ, start_response):
    app = wsgi.make_app(
        root="/mnt/bazaar/trunk/",
        prefix="trunk",
        readonly=False,
        enable_logging=False)
    return app(environ, start_response)

and my trac.ini file looks like:

The trac.ini file looks strange, because it has a large number of duplicate lines. Where does this come from? I'm particularly suspcious about the "tracbzr.backend.bzrconnector = disabled" lines. Try removing those.

I'm not sure where those came from, but that was the problem! Thank you for the quick reponse!
