-- For a few generic cache operations if not using Memcached
CREATE TABLE /*$wgDBprefix*/objectcache (

Add an objectcache table for limited caching when memcached isn't available. Currently using for the message cache to avoid reading every message separately. This now is only slightly slower than memcached in my tests when $wgUseDatabaseMessages is enabled, so it's a bit of a speedup for common hosts. 2004-05-09 05:12:55 +00:00			`-- For a few generic cache operations if not using Memcached`
added /$wgDBprefix/ in various places, to support upgrading from old prefixed databases, e.g. mine 2005-01-14 13:33:17 +00:00			`CREATE TABLE /$wgDBprefix/objectcache (`
* (bug 11450) Fix creation of objectcache table on upgrade patch-objectcache.sql had an extra 'binary' specifier which wasn't needed and causes the table creation to fail. Whoops! :) 2007-09-25 15:08:50 +00:00			`keyname varbinary(255) NOT NULL default '',`

Use InnoDB by default for table creations if available. 2005-05-02 08:40:17 +00:00
* Removed mysql5 SQL files, obviously we're collectively incapable of keeping them up to date. They were littered with errors. The only deliberate difference appears to be the table character set, which can be adjusted programatically using a variable. * Added table option variable to the SQL patch files, so now upgrading a non-standard schema won't leave your database horribly corrupted. * Added sql.php, for sourcing SQL files with MediaWiki variable substitution. * Disable MySQL's strict mode at session start for MySQL 4.1+, to avoid the various problems that occur when it is on. 2007-04-22 14:04:06 +00:00			`) /$wgDBTableOptions/;`
