tigefa4u projects Trac

New release candidate debian package

WikiContext: some semantic changes for relative wiki links:

1. `[/path]`: path is now relative to the Trac project (suggested by Tim Hatch)
2. `[//path]`: path is now relative to the Project URL (can be a parent URL for the Trac project itself, see `Context.local_url`)
3. `[..]`: links to the "parent" resource within the current pseudo-hierarchy (e.g. in the wiki)
4. `[./subpage]`: likewise, this links to a "sub" resource
5. `[../sibling]`: this links to a "sibling" resource

Added some unit tests and a handful of bugfixes.

WikiContext: introduce new `trac.wiki.api.Context` class to be used when rendering wiki content. Should fix #3711, #3842, #4144, #3936, #3958, #4139 and probably a few others.

Starting WikiContext working branch

VcRefactoring/BrowserQuickjump: removing branch merged in r4438

VcRefactoring/BrowserQuickjump branch merged in trunk. Completes #4223.

Fix #4369 re revision log header in verbose mode

VcRefactoring/BrowserQuickjump: implementing cmlenz's suggestion of merging the `branches` and `branch_folders` configuration options (and the same for tag)

Now there's only `branches` and `tags`:
{{{
[svn]
branches = trunk,branches/*
tags = tags/*
}}}
i.e. a "*" is used to specify that the content of the path should be used, instead of the path itself (and only subfolders are taken into account, not files).

Not only this simplifies the code, but this allows you to freely mix the fixed paths and the dynamic paths, in the order you want.

Make query "contains" filters case-insensitive on all db backends. Also
properly escape all LIKE queries. Closes #4363.

Ported r4433 to 0.10-stable (fixes #4332)
