Description Joel Natividad 2009-02-19 20:00:55 UTC
Currently, SRF-Ploticus creates a hash based on the query params, and if liveupdating is on, the query result set.

Though it may be slim, there is a small chance of a cache collision when two separate identical queries with liveupdating=false may retrieve the wrong results from the cache.

To eliminate this possibility, seed the hash with the article name and the query runnumber as well.
Comment 1 Joel Natividad 2009-02-20 21:29:32 UTC
Fixed in revision 47591 (

Seeded hash with $wgArticle->mTitle and $smwgIQRunningNumber to eliminate the possibility of cache collisions for identical ploticus queries across pages.
