zLOG triggers deprecation warnings in Zope >2.9
Below is an updated (2008-08-01) patch to fix this. (It does not touch the plugins directory. mathaction and latexwiki also use zLOG.)
Patch below. I'll leave it ugly as it is for convenient cutting from the source text. Later it should be indented for aesthetic reasons ;-):

might not be deprecated much longer --betabug, Tue, 20 Feb 2007 13:03:03 +0000 reply
Looking at this thread http://www.gossamer-threads.com/lists/zope/dev/205917 it looks like zLOG might not be deprecated much longer, since it's just a wrapper around the python logging module anyway. I don't think spending hours removing zLOG.LOG calls from ZWiki code is worth it - we would likely just be replacing it with another wrapper around the python logging module. Any reasons for really doing the change?
indeed, zLOG is undeprecated now --betabug, Tue, 20 Feb 2007 13:30:11 +0000 reply
See http://archives.free.net.ph/message/20070204.032739.0ddbd6a9.en.html "Undeprecated 'zLOG', which will remain a backward-compatibility shim for the Python logging module.".

I don't know, it might be worth doing, simply for cleanliness and consistency with modern zope code. Especially since there is a nice darcs patch here that claims to take care of it. I might try this later.

On the other hand: the patch doesn't apply (Bad patch bundle - I don't know why, it looks perfect). And it will conflict with more recent cleanups to the BLATHER, INFO etc. Better to just use it as inspiration.

I updated the patch (did also send via darcs but it does not show up on GeneralDiscussion). As Simon states above, I also think it should be applied even if zLOG is now undeprecated since it separates concerns in the code and gets rid of duplication.
