centralized trac.ini

[Manuzhai]

I was just trying to trick the mod_python handler into displaying a prettier page where you can choose from different projects, and while I got it done in the end, it was not a very pretty solution. This was mainly due to the fact that only the env knows about things like template locations, htdocs_location, and other stuff.

To make it easier to use Trac with multiple projects, I think Trac should have a central configuration file (e.g., /etc/trac.ini) which contains defaults for all the options in the env trac.ini that are reasonable. These options can than be overwritten in env-specific trac.ini's.

Would this be as useful as I think? I could whip up a patch if necessary. :)

Patch that adds a CENTRAL_CONFIG var.

[Christopher Lenz]

Well, trac.siteconfig already knows the location of all the default directories, and the other stuff is really environment specific. I don't see how a central configuration file would help very much there. The centralini.diff patch will obviously only work on Unix systems, and hardcoding the path isn't pretty.

A proper solution would be (IMHO) to add a PythonOption like TracEnvIndexTemplate to the mod_python handler. If you want to get fancy, you could allow setting constant HDF values for use in the template from the Apache config, like:

<Location /projects>
  SetHandler mod_python
  PythonHandler trac.ModPythonHandler
  PythonOption TracUriRoot /projects
  PythonOption TracEnvParentDir "/var/trac"
  PythonOption TracEnvIndexTemplate "/var/trac/index.cst"
  PythonOption TracTemplateVar "htdocs_common = /trac"
</Location>

I've been thinking something like this would be useful for me as well.

I think I'm going to try a solution that will look for a trac.ini in TracEnvParentDir (to avoid the hardcoded path) and will provide a sort of templating ability for using the project path in the central ini (e.g. repository_dir = /var/svn/<project>, though with a different syntax)

I've built an implementation of a templated index, following the idea that Chris gave above. Here's a link to my writeup: ​http://blog.mugfu.com/2005/03/29/template-ized-trac-indices/ The latest patch is in the comments there, and I'll attach a copy here as well.

patch to cleanly apply to [1467] plus

[Christopher Lenz]

I've checked code based on Jasons patch in [1498]. As that doesn't resolve the central trac.ini issue raised here, this ticket remains open.
