#13828 closed (fixed)

Refactor `dictsort` and `dictsortreversed` to make them more DRY

In django.template.defaultfilters, dictsort and dictsortreversed are almost the same except for the invocation of reverse() on the sorted list in the later function.

Now I have defined another function _dictsort(value, arg, reverse=False), and make dictsort and dictsortreversed call it.

It appears the diff attached was created from the template directory. diff's should be created against the base django directory.

I've attached a patch that is the same but with the diff generated from the root directory.

I can also confirm that the patch cleanly applies to trunk and tests pass.

Summary: [patch] Refactor `dictsort` and `dictsortreversed` to make them more DRYRefactor `dictsort` and `dictsortreversed` to make them more DRY

Both functions turn into one-liners in Python 2.4, so a common function isn't needed. The previous patch also had a subtle change in behavior: the original list was modified by use of filter. Current patch returns a new list instead. Also modified tests to explicitly check that the original list isn't modified.

PS. There already is a "has patch" flag. You don't need to write "patch" in the topic.
