Details

purgeParserCache.php file is a maintenance script to remove old objects from the parser cache. This script only works when the parser cache is in an SQL database, by setting $wgMainCacheType or $wgParserCacheType to their appropriate values.

Options/Arguments

Option	Description	Required?
--expiredate	Delete objects expiring before this date. The date can be specified in any format supported by the strtotime() function, like, for example, 20241025030459.	Optional
--age	Delete objects created more than this many seconds ago, assuming $wgParserCacheExpireTime has been consistent.	Optional
--dry-run	Perform a dry run, to verify age and date calculation.	Optional
--msleep	Milliseconds to sleep between purge chunks of $wgUpdateRowsPerQuery.	Optional
--tag	Purge a single server only. This feature is designed for use by large wiki farms where one has to purge multiple servers concurrently in order to keep up with new writes. This requires using the SqlBagOStuff "servers" option in $wgObjectCaches .	Optional

You must specify either expiredate or age.

Usage

php maintenance/purgeParserCache.php [ --expiredate| --age | --dry-run| --msleep| --tag ]

Terminal

$ php maintenance/purgeParserCache.php --age 30
