trac.wsgi does not work with multiple projects

[Michel Jouvin <jouvin@…>]

The template for trac.wsgi has a typo (in r8872, never used it before) which breaks the support for multiple projects: tt uses to trac.env_path_parent_dir instead of trac.env_parent_dir leading to an error in trac.web.main when trying to open the environment. This options is also undocumented in the mod_wsgi page.

BTW, the documentation about mod_wsgi support in Trac is very basic. In particular it suggests to define PYTHON_EGG_CACHE where probably it's better to use WSGIPythonEggs in embedded mode or the python-eggs option of daemons. If there is a good reason not to do it, it's probably worth documenting it too…

My somebody apply this patch to the trunk, this bug is annoying as it requires an edit at each upgrade and IMO is very trivial!

Thanks for the patch.

Patch applied in [8958]. Thanks!

[Lele Gaifax]

The problem seems still present: the same change is required a few lines below (source:trunk/trac/admin/templates/deploy_trac.wsgi#L28).

[Remy Blank]

Right, my bad. I should have checked more carefully.

Fixed in [9947].
