Hi all,
I noticed that SuggestBot's struggled with saving a user page earlier
this week, see http://en.wikipedia.org/w/index.php?title=User_talk:The_Master_of_Mayhem&ac…
Notice the larger number of saves that have a diff size of 0 bytes.
I suspect it's due to the size of the page, 300+kB, is this a typical
problem? If not I can start digging to see if I can figure out what's
going on. If it is a common problem, what are some typical ways of
solving it? Just checking the page size and skip/abort if it's too
large?
Regards,
Morten
Scott,
Nemo is referring to the dumpgenerator.py being broken on MediaWiki
versions above 1.20, and it should not actually affect older MediaWiki
versions.
You can safely continue with your grab. :)

Thank you again for your useful suggestions!
However, as already noted,
https://www.mediawiki.org/wiki/API:Query#Continuing_queries doesn't give
any info about supported releases.

P.s.: Small unreliable "temporary" things in MediaWiki, like the
"powered by MediaWiki" sentence we grep for, are usually the most
permanent ones, although I don't like it.

+1
https://www.mediawiki.org/wiki/API:Allpages ,
https://www.mediawiki.org/wiki/API:Lists and
https://www.mediawiki.org/wiki/API:Query#Continuing_queries don't really
shed any light.

Well, that in an ideal world. In this one, the best would probably be
suggestions for simple libraries to be used to solve such small
problems? (Which can become very big if one doesn't follow API evolution
very closely or know it's history from the beginning of time.)

It's completely broken:
https://code.google.com/p/wikiteam/issues/detail?id=56
It will download only a fraction of the wiki, 500 pages at most per
namespace.
Let me reiterate that
https://code.google.com/p/wikiteam/issues/detail?id=44 is a very urgent
bug and we've seen no work on it in many months. We need an actual
programmer with some knowledge of python to fix it and make the script
work properly; I know there are several on this list (and elsewhere),
please please help. The last time I, as a non-coder, tried to fix a bug,
I made things worse
(https://code.google.com/p/wikiteam/issues/detail?id=26).
Only after API is implemented/fixed, I'll be able to re-archive the 4-5
thousands wikis we've recently archived on archive.org
(https://archive.org/details/wikiteam) and possibly many more. Many of
those dumps contain errors and/or are just partial because of the
script's unreliability, and wikis die on a daily basis. (So, quoting
emijrp, there IS a deadline.)
