Extension:RecentChangesLogFilter

RecentChangesLogFilter is a MediaWiki extension to filter log entries displayed in Special:RecentChanges.

It was primarily created to be able to hide all user creation log entries from recent changes in case the wiki is targetted by a spam bot network where many accounts are created. Hence, hiding user creation log entries is the default behaviour unless configured otherwise.

The filter is enabled by default and can be disabled at any time using the configuration options at the top of the recent changes list. In addition, registered users can change the default behavior for themselves in their preferences under the “recent changes” section.

Installation
To install this extension, extract the extension’s files into a folder  in the   directory and add the following line to  :

require_once( "$IP/extensions/RecentChangesLogFilter/RecentChangesLogFilter.php" );

Configuration
By default, the only log type that is hidden is the user creation type. It is possible to change this behaviour by modifying the  configuration variable. It is also possible to hide more than just one log type.

For example to hide uploads instead of user creations, set the configuration variable like this:

$wgRecentChangesLogFilterTypes = array( 'upload' );

To hide blocks and page protections, set the variable like this:

$wgRecentChangesLogFilterTypes = array( 'block', 'protect' );

You can find a list of valid log types here but note that some extensions or configuration settings, like $wgNewUserLog, may add additional types.

User preferences
The default behavior is to have the filter activated and hide log entries from recent changes. To give the extension the inverse behavior and make the filter disabled by default—while still allowing users to enable it temporarily on Special:RecentChanges, or permanently in their preferences—add the following line to :

$wgDefaultUserOptions['rchidelogs'] = 0;

Messages
When changing the types to hide, it is recommend to also change the system message, which is responsible for the link that is displayed on  , to match the new behavior. By default it will only mention user creation logs to match the default configuration. For example when hiding block and page protections like above, you might want to set it to “$1 block and protection logs”.

Similarly,  is responsible for the preferences text and should be adjusted as well.
