Move template modules to django.core.template package

[Adrian Holovaty]

There are too many template-related modules lying around in django.core. We should create a django.core.template package and put the following modules in it:

• django.core.defaultfilters
• django.core.defaulttags
• django.core.template (would be django.core.template.__init__ to retain identical interface)
• django.core.template_loader
• django.core.template_file

To maintain backwards compatibility, django.core.template_loader should still exist (at least until 1.0), because a lot of Django code does from django.core.template_loader import ....

We should probably do this before #582 and #625, because those tickets both add template-related modules to django.core.

Patch that causes circular-import problem.

I'm running into circular import problems in the implementation. See the attached patch, 626_import_error.patch. Any ideas?

This patch works and includes some of the changes that were omitted from the previous patch.

Svn diff utterly sucks. It does not include file moves or directory creations.
So to apply this, do from your trunk checkout:

mkdir django/core/template/
svn add django/core/template/
svn move django/core/template.py django/core/template/__init__.py
mkdir django/core/template/loaders/
touch django/core/template/loaders/__init__.py
svn add django/core/template/loaders/
svn move django/core/template_file.py django/core/template/loaders/filesystem.py
patch -p0 < /path/to/626_working.patch

I think that is it. Untested procedure. Little did I think we would be writing manual patch scripts on the verge of 2006....
bring on bazaar-ng ;-)

Got it. Basically you avoided the issue by importing specific objects from django.core.template instead of doing "from django.core import template".

(In [867]) Fixed #626 -- Moved template modules to django.core.template package. django.core.template_loader is deprecated, in favor of django.core.template.loader.
