* There is no code covering page moves and deletions yet; do those hang on LinksUpdate as well?

(cross-posting wikitech-l and commons-l) I created a new extension ("CategoryIntersection") that allows for quick lookup of pages (and image) in intersecting categories. That would enable wiki(m|p)edia sites to use categories as tags, eliminating the need for oh-so-specialized categories. Intersection of two categories works very fast, but intersecting more categories is possible, and already implemented; the maximum number can be limited. I tried it on my (mostly empty) MediaWiki test setup, and it works peachy. However, *I NEED HELP* with * testing it on a large-scale installation * integrating it with MediaWiki more tightly (database wrappers, caching, etc.) * Brionizing the code, so it actually has a chance to be used on Wikipedia and/or Commons Techinical notes: * This was recently discussed on wikitech-l * More than two intersections are implemented by nesting subqueries * Hash values are implemented as VARCHAR(32). Could easily switch to INTEGER if desirable (less storage, faster lookup, but more false positives) * The hash values will only give good candidates (pages that *might* intersect in these categories). The candidates have then to be checked in a second run, which will have to be optimized; database people to the front! * Table to store hash values has to be created manually; SQL is in the main file * I didn't implement code to fill the table for an existing installation; however, since hash table updates solely hang on the LinksUpdate hook, this should be easy * There is no code covering page moves and deletions yet; do those hang on LinksUpdate as well? * SQL queries are currently "plain text" and not constructed through the DB wrappers; I wan't sure how to do that for the subqueries Cheers, Magnus _______________________________________________ Commons-l mailing list Commons-l(a)lists.wikimedia.org https://lists.wikimedia.org/mailman/listinfo/commons-l
