Extension:AbuseFilter/da

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.

Krav
There are no required dependencies for this extension.

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

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:

Creating and managing filters
Når udvidelsen er installeret, kan filtre oprettes/testes/ændres/slettes, og logfiler kan tilgås fra misbrug filter håndterings side Special:AbuseFilter.


 * Regel format - The basics of how to write a filter
 * Handlinger
 * Globale Regler
 * Guide til optimering af forbrugs grænse.
 * Importeres filtre fra Wikipedia: Når du har installeret udvidelsen, skal du gå til w:Special:AbuseFilter, vælge et filter (sig w:Special:AbuseFilter/3), klik derefter på "Eksportere dette filter til en anden wiki", kopier teksten, gå til "Special:AbuseFilter/import" på din wiki, indsætte teksten.

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
Liste oplysninger om filtre


 * Parameters
 * : The filter id to start enumerating from
 * : The filter id to stop enumerating at
 * : The direction in which to enumerate (older, newer)
 * : Show only filters which meet these criteria (enabled|!enabled|deleted|!deleted|private|!private)
 * : The maximum number of filters to list
 * : Which properties to get (id|description|pattern|actions|hits|comments|lasteditor|lastedittime|status|private)

When filters are private, some of the properties specified with  will be missing unless you have the appropriate user rights.

Emergency throttling
AbuseFilter comes with a feature that automatically throttles (disable) filters that have been edited recently and match a certain theresold 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: Throttled filters can be identified in the list of filters (Special:AbuseFilter) with the state. Throttling happens silently, and there's no way to see when a filter got throttled.
 * $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.
 * $wgAbuseFilterProfileActionsCap: Maximum number of recent actions to count against the threshold. Note that each action increments a counter, and once this counter reaches this configured value, this counter and the number of recent actions that matches all filters are reset to 0.

When a filter gets throttled, it doesn't perform any dangerous action (the ones specified in ), and only "safe" actions are allowed. 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 somethin 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. Filters can also get randomly throttled if the action count reaches $wgAbuseFilterProfileActionsCap, causing all filter matches count to reset to 0, and then someone repeatedly makes a filter to hit.

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 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)
