Issues Open tasks · Report a bug

The AbuseFilter extension allows privileged users to set specific actions to be taken when actions by users, such as edits, match certain criteria. For example, a filter could be created to prevent anonymous users from adding external links, or to block a user who removes more than 2000 characters.

Riquisiti

Nstallazzioni

  • Download and place the file(s) in a directory called AbuseFilter in your extensions/ folder.
  • Run Composer to install PHP dependencies, by issuing composer install in the extension directory. (See T173141 for potential complications.)
  • Add the following code at the bottom of your LocalSettings.php:
    wfLoadExtension( 'AbuseFilter' );
    
  • Run the update script which will automatically create the necessary database tables that this extension needs.
  • Yes Done – Navigate to Special:Version on your wiki to verify that the extension is successfully installed.

To users running MediaWiki 1.26 or earlier:

The instructions above describe the new way of installing this extension using wfLoadExtension() If you need to install this extension on these earlier versions (MediaWiki 1.26 and earlier), instead of wfLoadExtension( 'AbuseFilter' );, you need to use:

require_once "$IP/extensions/AbuseFilter/AbuseFilter.php";


Dritti utenti

Once you installed the extension, you'll have to set up the user rights in LocalSettings.php.

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;
Filters marked as private can only be viewed by users with either the abusefilter-modify or abusefilter-view-private permission.

Creating and managing filters

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.

$wgAbuseFilterProfileActionsCap 10000 Number of action that determines when to reset profiling stats.


API

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

List information about filters

Parameters
  • 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.

Esempi

List non-private abuse filters

list = abuselog

List instances where actions triggered an abuse filter.

Parameters
  • aflstart: The timestamp to start enumerating from
  • aflend: The timestamp to stop enumerating at
  • afldir: The direction in which to enumerate (older, newer)
  • afluser: Show only entries where the action was attempted by a given user or IP address.
  • afltitle: Show only entries where the action involved a given page.
  • aflfilter: Show only entries that triggered a given filter ID
  • afllimit: The maximum number of entries to list
  • aflprop: Which properties to get (ids|user|title|action|result|timestamp|details)
Example

List instances where the abuse filter was triggered in response to actions from the user "SineBot"

Possible errors

  • Some users might experience that creating new filters or modifying old filters fail and the user just gets redirected to the original page. If the Wiki is using SSL certificates, this error could possibly be because of the $wgServer value, which might be using "http://" instead of "https://". An indication of this error will be, the browser giving https warning for Special:AbuseFilter pages. (Topic:T23dyyih0ofjada5)
