Bringing Sphinx search support up to code: broken out to a plugin, now supports multiple sites on a single server.
Upgrade notes: * Index names have changed from hardcoded 'Identica_people' and 'Identica_notices' to use the database name and actual table names. Must reindex. New events: * GetSearchEngine to override default search engine class selection from plugins New scripts: * gen_config.php generates a sphinx.conf from database configuration (with theoretical support for status_network table, but it doesn't seem to be cleanly queriable right now without knowing the db setup info for that. Needs generalized support.) * Replaced old sphinx-indexer.sh and sphinx-cron.sh with index_update.php Other fixes: * sphinx.conf.sample better matches our live config, skipping unused stopword list and using a more realistic indexer memory limit Further notes: * Probably doesn't work right with PostgreSQL yet; Sphinx can pull from PG but the extraction queries currently look like they use some MySQL-specific functions.
