Summary: Bug in catlib.py (Problems with caching-mechanism)

Initial Comment:
I detected a bug in catlib.py that is due to the caching-functionality.
Line 132 (if not page in cache:) causes problems.

If an article is part of [[Category:A]] and [[Category:B]] and a script iterates over both categories, the article is not yielded by catB.articles() because it was cached during an earlier call of catA.articles().

It would be better if the call of catB.articles() really yields all articles in this category, because sometimes the plain names of the articles are of interest.

I did not fix the bug by myself, because I do not understand the caching-mechanism by now.


My view of the sources is on revision 4720 (updated today).

Python seems to have some weird feature (or bug?) about default unused
parameters: it keeps them for the next run. Will fix that soon.

To solve my problem I put line 134 of catlib.py (yield ARTICLE, page) out
of the if-block of line 132 (if not page in cache:).
