The rebuildConceptCache.php maintenance script manages the concept caching functionality provided by SMW. The help page on concept caching provides detailed additional information on how to use this maintenance script.
- This maintenance script depreciated the former "SMW_conceptCache.php" script starting with Semantic MediaWiki 1.9.2 while options and usage at that time remain the same.
- Note: It is strongly encouraged to make the transition to this new script to take advantage of the new features added since and because the old one will will be removed with the release of Semantic MediaWiki 3.0 in early 2017.
- If SMW is not installed in its standard path then the "MW_INSTALL_PATH" environment variable must be set. See README in the maintenance directory.
Note: This only shows the script specific parameters.
- Display this help message
- Whether to supress non-error output
- Location of "LocalSettings.php", if not default
- For specifying the wiki ID
- Output globals at the end of processing for debugging
- Set a specific memory limit for the script, "max" for no limit or "default" to avoid changing it
- The protocol and server name to use in URLs, e.g. http://www.semantic-mediawiki.org. This is sometimes necessary because server name detection may fail in command line scripts.
Script dependant parameters
- The DB user to use for this script
- The password to use for this script
Script specific parameters
