Upgrade
The file /usr/lib/python2.3/site-packages/trac/notification.py was substantially modified to support looking up email addresses in LDAP, and will need to be re-adjusted if we upgrade to a new version of Trac.

Creating a trac instance
$ sudo trac-admin /var/www/trac/ initenv $ sudo trac-admin /var/www/trac/ permission add  TRAC_ADMIN $ sudo chown -R apache:apache /var/www/trac/


 * Update /var/www/trac///conf/trac.ini to enable email notification.

cpu = select cpu.label = CPU cpu.options = Unspecified|x86-32|x86-64|OSX/PPC|OSX/Intel|Other|All cpu.value = Unspecified

= Trac Spam =

We have had problems with trac spam when ticket create and ticket modify permissions were set to anonymous (the default). To get around this most (all?) instances have been changed to require authenticated users to do these actions.

But some projects strongly desire to support anonymous ticket creation and modification and at some point this might be viable using image captcha technology to keep out the spammers. A Trac plugin for this is apparently under development, and described at:
