WikiSystem object instanciation and holding page names

[Shun-ichi Goto <gotoh@…>]

On using multi project, WikiSystem class object in trac/wiki/api.py fetch the page names in the project from db only when instanciation. Because the object holds them within other project, as result, wiki page links are rendered as missed page although the page is actually exist.

Actually, the problem is that notifications about added/removed pages only happen in a single process/interpreter, which is a problem when running under mod_python.

[Christian Boos]

Maybe, but there's anyway a problem here, even in the single process case: the link resolvers are stored in a Formatter class attributes (Formatter._link_resolvers), therefore tying a specific environment to the Formatter, which is not something one wants to do in a multi-environment setup.

I'm currently fixing that in the InterTrac branch.

[Christopher Lenz]

Fixed in [1977].

(cboos: that's a different issue then. If you have a fix, please apply it to trunk, too.)

[Shun-ichi Goto <gotoh@…>]

[1977] does not fix this issue, but [1979] does. Now the page lines are rendered correctly on mod_python multi-project environment.

[Christopher Lenz]

Yeah, [1977] is the fix for a single-project setup, [1979] for multi-project. The latter fixes the issue cboos raises above.

Thanks for verifying.
