CORE - Loader should load single-file plugins after egg plugins

[ilias@…]

The trac loader should load single-file plugins after the egg-plugins.

Single-File plugins rely more on egg-plugins than egg-plugins on single-file-plugins.

If any dependency is required, do not use a single-file plugin. The requirement should be documented in a way Trac (and setuptools) can see, which requires an egg. Using setuptools is not hard enough that it warrants additional hackery around the single-file system IMO. Propose a wontfix for this.

Single-file "system"? - what system? there's just a piece of draft-code.

Keep things complicated, thus users struggle even more and need the expertise of the team members.

"hackery"? - no hackery needed:

simply move this code block (single-file loader):

source:trunk/trac/loader.py@3557#L43​

after this one (egg loader):

source:trunk/trac/loader.py@3557#L62​

To have a more logical plugin-type-load-order (single-file after egg)

[Christopher Lenz]

It certainly makes sense to load single-file plugins after eggs.
