Trac help links broken when wiki module is disabled

[Martijn Pieters <trac.edgewall.org@…>]

Various modules display a helpful message along the bottom of the page to direct users to documentation. For example, the code browser shows:

Note: See TracBrowser for help on using the browser.

The ticket module does this as well; the bottom of this ticket page has such a link, as does the query page.

These links depends on the wiki module being enabled. When that module is disabled, the links in question lead to 404 Not Found errors.

These links should be made conditional on the wiki module being active. For bonus points, the links could point to trac.edgewall.org instead, although this may lead to confusion as trac.edgewall.org deals with the latest released version, not the active version.

Or, more radical, the help pages could be served anyway, in a limited fashion, as a read-only wiki serving only these help pages.

Okay, I realise now that this can be considered a dupe of ticket #2656, and certainly TracDev/Proposals/NewHelp would fix this particular issue nicely.

However, perhaps the temporary workaround of making the links conditional is something to be considered for a future 0.11 release?

Yup, your request mirrors the general intention of the new help system.

Closing as duplicate of #2656.
