The AbuseFilter extension allows privileged users to set specific controls on actions by users, such as edits, and create automated reactions for certain behaviors.
Requirements[edit | edit source]
It's not needed to install any dependencies for this extension, but you still might want to install Extension:AntiSpoof to use string normalization features.
Installation[edit | edit source]
- Download and extract the file(s) in a directory called
extensions/folder. If you're a developer and this extension is in a Git repository, then instead you should clone the repository using:
git clone https://gerrit.wikimedia.org/r/p/mediawiki/extensions/AbuseFilter.git
- Add the following code at the bottom of your LocalSettings.php:
- Run the update script which will automatically create the necessary database tables that this extension needs.
- Done! Navigate to "Special:Version" on your wiki to verify that the extension is successfully installed.
User rights[edit | edit source]
Once you installed the extension, you'll have to set up the user rights in
|abusefilter-modify||Modify abuse filters|
|abusefilter-view||View abuse filters|
|abusefilter-log||View the abuse log|
|abusefilter-log-detail||View detailed abuse log entries|
|abusefilter-private||View private data in the abuse log|
|abusefilter-modify-restricted||Modify abuse filters with restricted actions|
|abusefilter-revert||Revert all changes by a given abuse filter|
|abusefilter-view-private||View abuse filters marked as private|
|abusefilter-log-private||View log entries of abuse filters marked as private|
|abusefilter-hide-log||Hide entries in the abuse log|
|abusefilter-hidden-log||View hidden abuse log entries|
For example, the following sample configuration would allow sysops to do everything they want with AbuseFilter, and everyone to view the log and see public filter settings:
$wgGroupPermissions['sysop']['abusefilter-modify'] = true; $wgGroupPermissions['*']['abusefilter-log-detail'] = true; $wgGroupPermissions['*']['abusefilter-view'] = true; $wgGroupPermissions['*']['abusefilter-log'] = true; $wgGroupPermissions['sysop']['abusefilter-private'] = true; $wgGroupPermissions['sysop']['abusefilter-modify-restricted'] = true; $wgGroupPermissions['sysop']['abusefilter-revert'] = true;
Abuse filter management[edit | edit source]
Once the extension has been installed, filters can be created/tested/changed/deleted and the logs can be accessed from the Abuse filter management page Special:AbuseFilter.
- The rules format
- Global Rules
- To Import filters from Wikipedia: When you have installed the extension, go to w:Special:AbuseFilter, choose a filter (say w:Special:AbuseFilter/3), then click "Export this filter to another wiki", copy the text, go to "Special:AbuseFilter/import" on your wiki, paste the text.
Configuration[edit | edit source]
|Variable name||Default value||Description|
||The possible actions that can be taken by abuse filters.|
|$wgAbuseFilterConditionLimit||1000||The maximum number of 'conditions' that can be used each time the filters are run against a change. (More complex filters require more 'conditions').|
|$wgAbuseFilterValidGroups||'default'||The list of "groups" filters can be divided into. By default there is only one group.|
|$wgAbuseFilterEmergencyDisableThreshold||0.05||Disable a filter if it matched more than 2 edits, constituting more than 5 % of the actions which were checked against the filter's group in the "observed" period (at most one day), unless the filter has been changed in the last 86400 seconds (one day)|
||Name of AbuseFilter's parser class.|
|$wgAbuseFilterStyleVersion||Like $wgStyleVersion, but only for this extension. Developers should bump this number every time time they change any of the .css/.js files.|
||Users must have the "abusefilter-modify-restricted" user right as well as "abusefilter-modify" in order to create or modify filters which carry out these actions.|
||Like $wgRC2UDPPrefix, but only for AbuseFilter?|
||Like $wgRC2UDPAddress, but only for AbuseFilter?|
||Like $wgRC2UDPPort, but only for AbuseFilter?|
||Name of a database where global abuse filters will be stored in (only supported in the latest, development version).|
||Set this variable to true for the wiki where global AbuseFilters are stored in (only supported in the latest, development version).|
||Duration of blocks made by AbuseFilter|
||Duration of blocks made by AbuseFilter on users who are not logged in. The value of $wgAbuseFilterBlockDuration will be used if this is not set.|
API[edit | edit source]
AbuseFilter adds two API list modules, one for details of abuse filters ("abusefilters") and one for the abuse log, since it is separate from other MediaWiki logs ("abuselog"). It is not possible to create or modify abuse filters using the API.
list = abusefilters[edit | edit source]
List information about filters
abfstartid: The filter id to start enumerating from
abfendid: The filter id to stop enumerating at
abfdir: The direction in which to enumerate (older, newer)
abfshow: Show only filters which meet these criteria (enabled|!enabled|deleted|!deleted|private|!private)
abflimit: The maximum number of filters to list
abfprop: Which properties to get (id|description|pattern|actions|hits|comments|lasteditor|lastedittime|status|private)
When filters are private, some of the properties specified with
abfprop will be missing unless you have the appropriate user rights.
