Bug ID: 55754
Summary: list=allcampaigns API can run slowly or timeout if
data not cached
Product: MediaWiki extensions

ampaigns&uclimit=500

Currently the upload campaigns branch of the Android Commons app uses
UploadWizard's list=allcampaigns API to periodically refresh the list of
campaigns.
Unfortunately this can run really slowly on Commons, especially if the parsed
titles/descriptions/etc aren't cached due to a software update, massive cache
clear, or selection of a new language. The worst case is a timeout or outright
HTTP 500 error.
A few possibilities:
* (probably easy) could aggressively limit the number of items returned when
not cached, so you at least get a fast result with fewer items instead of a
timeout. This allows clients to continue fetching to get the rest of the
results as they are built.
* (a bit more work) could do more lightweight rendering -- at fetch time we
really only need the title; we could fetch the description and other fields
when we go to upload something. Separately caching/rendering 'just titles' and
'whole field sets' could allow the list to run *much* faster.
* (probably not feasible?) could pre-cache items in the JobQueue after their
dependencies change?
