[PATCH] Add shared htdocs location

[itamaro]

Allow multiple Trac environments to share the same htdocs directory,
similar to the concept of a shared templates directory.

Attached patch​ (against 0.12 tag) adds htdocs_dir to [inherit] option group, and maps this directory to chrome/shared URL in Chrome.get_htdocs_dirs() under the 'shared' prefix.

Add shared htdocs_dir directory and return it from Chrome.get_htdocs_dirs()

Can you explain a bit more what would be the use case for this?

[itamaro]

of course.

This patch is a result of the following discussion on the mailing list:
​http://groups.google.com/group/trac-users/browse_thread/thread/ad54345c3fddd3be/b79c4ca9b4d56fab

Ok, I see, thanks for the reference.

Can you update the option documentation by also saying "This can be useful in site.html" (as well as the "since").

Which makes me think about creating a default site.html (with the same content as in TracInterfaceCustomization#SiteAppearance) on initenv, as well as a default site.css (empty, or even with something distinctively not "edgewall" like, to help for #6185). That would make customization of new environments a tad easier.

IIRC, we removed a stock site.html quite recently (#8869), to avoid its hiding a shared site.html.

Ah yes, [8952] which produces a site.html.sample.

Still, there are too many steps to perform in order to do some simple CSS customizations (like, adding a color for a group in [milestone-groups] ). Perhaps we could always provide a link to the site.css files present in any of the get_htdocs_dirs()?

Yes, I was thinking the same.

Updated (see the branch on my fork at GitHub: ​http://github.com/itamaro/trac/tree/9462-shared-htdocs).

Change committed in r10167.

I also committed the other little fixes found there, thanks!
