AbuseFilter

2020 Coolest Tool
Award Winner

in the category
Quality


Az AbuseFilter (Vandálszűrő) kiterjesztés az arra jogosult felhasználóknak lehetővé teszi egyes szerkesztési mintákhoz tartozó szűrők beállítását.

Például lehetséges az anonim szerkesztők számára megtiltani külső hivatkozások beszúrását, vagy a 2000 karakternél többet törlőket blokkolni.


Telepítés

  • Töltsd le a kiterjesztés fájljait, és mentsd el az extensions/ mappán belüli AbuseFilter könyvtárba.
    Developers and code contributors should install the extension from Git instead, using:cd extensions/
    git clone https://gerrit.wikimedia.org/r/mediawiki/extensions/AbuseFilter
  • Csak Gitről telepítés esetén futtasd a Composert a PHP-függőségek telepítéséhez a composer install --no-dev parancs kiadásával a kiterjesztés könyvtárában. (Lásd a task T173141 lapot a lehetséges problémákért.)
  • Add hozzá az alábbi kódot a LocalSettings.php fájlod aljára: 
    wfLoadExtension( 'AbuseFilter' );
  • Futtasd le a frissítőszkriptet, ami automatikusan létrehozza a kiterjesztés által igényelt táblákat az adatbázisban.
  • Állítsd be a szükséges módon.
  •   Kész – A Special:Version oldalon ellenőrizheted, hogy a kiterjesztés ténylegesen feltelepült-e.

When installing from Git, please note that this extension requires Composer .

So, after installation from Git change to the directory containing the extension e.g. "../extensions/AbuseFilter/" and run composer install --no-dev, or when updating: composer update --no-dev.

Alternatively as well as preferably add the line "extensions/AbuseFilter/composer.json" to the "composer.local.json" file in the root directory of your wiki like e.g. 

{
	"extra": {
		"merge-plugin": {
			"include": [
				"extensions/AbuseFilter/composer.json"
			]
		}
	}
}

Beállítás

Felhasználói jogosultságok

Miután telepítetted a kiterjesztést, a "LocalSettings.php"-ben szükséges a jogosultságok definiálása.

Emergency throttling

AbuseFilter comes with a feature that automatically throttles (disables) filters that have been edited recently and match a certain threshold of the latest actions.

This is done to prevent harmful edits on the filters to block every user that performs an action on the wiki or similar.

The condition to disable the filter depend on those variables:

  • $wgAbuseFilterEmergencyDisableThreshold - Percent of matches over the total amount of actions in the observed period.
  • $wgAbuseFilterEmergencyDisableCount - Count of matches of the filter in the observed period.
  • $wgAbuseFilterEmergencyDisableAge - Age of the filter to take it into account. If the last edit of the filter is older than this number of seconds, the filter won't be throttled, unless it's already throttled.

Throttled filters can be identified in the list of filters (Special:AbuseFilter) with the state Bekapcsolva, Magas találati arány. Throttling happens silently, and there's no way to see when a filter got throttled, except when Extension:Echo is installed, then a notification is sent to the user who was last to modify the filter.

When a filter gets throttled, it doesn't perform any dangerous action (actions usually restricted to special rights like blocking the user, or removing it from groups, controlled by $wgAbuseFilterActionRestrictions), and only "safe" actions are allowed (the ones that can warn or prevent the ongoing action). Throttled filters don't get enabled automatically. To disable the throttling, you need to edit the filter. Note that you need to actually change something from the filter: changing something from the filter's notes is sufficient.

Note that editing the filter updates its age, and can cause it to be disabled if it reaches again the conditions to be throttled in a short period since the last edit, leading to a unusable filter if your wiki has more abuse edits than legitimate ones.

Szűrők létrehozása és kezelése

A kiterjesztés telepítése után a szűrők kezelése és a naplók megtekintése a Special:AbuseFilter lapon lehetséges.

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

Paraméterek
  • 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|protected|!protected)
  • 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.

Lehetséges hibák

  • 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)

Integration with other extensions

You can integrate AbuseFilter with other extension in various ways.

Adding variables for filtering

It is possible to add new variables, to be used in abuse filters. A list of examples is available . To do that, you should:

  • Add a handler for the AbuseFilter-builder hook. To add a variable, you should use $builder['vars']['variable_name'] = 'i18n-key';, where variable_name is the name of the variable, and i18n-key is the fragment of an i18n key. The full key will be abusefilter-edit-builder-vars-{$your_key}.
  • Add the i18n messages you chose at the previous point.
  • Choose a hook handler where the variable will be computed. Depending on your use case, you could:
    • Implement the AbuseFilter-generateTitleVars hook; this is specifically thought for page-related variables;
    • Implement the AbuseFilter-generateUserVars hook; this is specifically thought for user-related variables;
    • Implement the AbuseFilter-generateGenericVars hook; this is for variables not bound to a specific page or user;
    • Implement the AbuseFilterAlterVariables hook; this is a bit more flexible than the other hooks, but it has a downside: your variable will not be available when examining past RecentChanges entries. If you want to implement that feature (and it's recommended to do so), you should use one of the hooks listed above, and use its third parameter ($RCRow).
  • Inside the hook handler, there are two ways to add a variable:
    • The "direct" way is calling $vars->setVar( 'var_name', var_value );. This is ideal only when the value is easy and quick to compute: the value is computed even if no active filter will use it.
    • The "lazy" way is calling $vars->setLazyLoadVar( 'var_name', 'method_name', $params );. Here, 'method_name' is a (unique) identifier that will be used to compute the variable (it's recommended to prefix it with the name of your extension). To register the method, you should add a handler for the AbuseFilter-computeVariable hook; therein, you should check if the $method passed matches your 'method_name', and if so, compute the variable. Lastly, $params is an array of parameters that you'll need to compute the variable; these are passed to the computeVariable hook handler. For an example of this, you can check out CentralAuth's global_user_groups.

Adding custom actions

You can add custom action handlers, so that each filter may perform further actions. To do that, you choose a name for the action ('my-action' from now on), and then:

  • Create a class named e.g. MyAction, that should extend \MediaWiki\Extension\AbuseFilter\Consequence, which can also implement HookAborterConsequence or ConsequencesDisablerConsequence
  • Add a subscriber to the AbuseFilterCustomActions hook; the subscriber should provide a callback as documented in the hook documentation, that returns an instance of the class created above, for instance:
class MyAction extends \MediaWiki\Extension\AbuseFilter\Consequence {
    public function run() {
        throw new \Exception( 'Write me' );
    }
}

public function onAbuseFilterCustomActions( &$actions ) {
    $actions[] = function ( \MediaWiki\Extension\AbuseFilter\Consequence\Parameters $params, array $rawParams ) : MyConsequence {
        return new MyAction( $params, $rawParams );
    };
}

Then you should add the following i18n messages; you can replace 'my_action' with e.g. 'block' to see what the messages are for:

  • 'abusefilter-edit-action-${my_action}'
  • 'abusefilter-action-${my_action}'

Adding rule groups

You can also add extra rule groups, which can be used to group existing abuse filters. Note that, at the moment, each filter can only be in a single group (T116642). Currently, the only known consumer of this feature is Extension:StructuredDiscussions . To do that, you should:

  • Append the name of the group to $wgAbuseFilterValidGroups.
  • Add some code to run the filters with your group. Note that AbuseFilter won't do that on its own. To do that, you should construct an AbuseFilterRunner object, passing in the name of your group.
