           Summary: API: Multiple page histories
           Product: MediaWiki

I have a particular use case for the API that could be streamlined a little.

It would be useful to have basic info for the last few revisions to a page
(say, 10 or so), for RC patrolling purposes, to help avoid the problem of
people reverting to the wrong revision when trying to deal with vandalism.

This is easy to do with prop=revisions. At the moment, though, it can only be
done one page at a time, unless I know the revision IDs beforehand, which I
don't, and a separate page history request on top of the diff request for every
change being reviewed is a little excessive, so I don't do it. (API diffs
wouldn't help here as the diff query would work in such a way as to make
combining it with a page history query impossible).

What I would like to be able to do is use something like the following query
string:

action=query&titles=Foo|Bar|Baz&prop=revisions&rvlimit=10

and have it return the last 10 revisions for each of the pages Foo, Bar and
Baz, i.e. 30 revisions in total. At the moment, of course, this doesn't work
because rvlimit can only be used with a single page. Obviously the
limit-checking code would have to be rewritten to check (rvlimit * title count)
<= 500 rather than rvlimit <= 500. As far as I can tell, asking for X revisions
this way should be no more of a performance hit than asking for X arbitrary
revisions, which is already possible. I'd probably give it about five titles
per query, so this would cut the number of queries needed to get the data by
four-fifths.
