Extension:AbuseFilter/ru

Расширение AbuseFilter позволяет привилегированным пользователям устанавливать фильтры, контролирующие действия участников и автоматически реагирующие на определённое поведение.

Например, может быть создан фильтр, чтобы запретить анонимным пользователям добавлять внешние ссылки или блокировать пользователей, удаляющих более 2000 символов.

 * 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:
 * - Percent of matches over the total amount of actions in the observed period.
 * - Count of matches of the filter in the observed period.
 * - 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.
 * - 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.

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.

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 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. Filters can also get randomly throttled if the action count reaches, causing all filter matches count to reset to 0, and then someone repeatedly makes a filter to hit.

Создание и управление фильтрами
После того, как расширение установлено, фильтры могут быть созданы/проверены/изменены/удалены и журналы доступны на странице управления фильтрами злоупотребления Special:AbuseFilter.

 * Чтобы импортировать фильтры из Википедии: когда вы установили расширение, перейдите на страницу w:Special:AbuseFilter, выберите фильтр (w:Special:AbuseFilter/3), затем нажмите «Экспортировать этот фильтр на другую wiki», скопируйте текст, перейдите в «Special:AbuseFilter/import» в вашей wiki, и вставьте текст.

API
AbuseFilter добавляет два API-модуля, один для фильтров злоупотреблений ("abusefilters") и один для журнала злоупотреблений, так как он является самостоятельным журналом ("abuselog").

list = abusefilters
Список информации о фильтрах


 * Параметры:
 * - 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)

Когда фильтры являются непубличными, некоторые свойства с указанием функции  будут отсутствовать, если у вас нет соответствующих прав доступа.

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)

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. To do that, you should:


 * Add a handler for the hook. To add a variable, you should use , where   is the name of the variable, and   is the fragment of an i18n key. The full key will be.
 * 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 hook; this is specifically thought for page-related variables;
 * Implement the hook; this is specifically thought for user-related variables;
 * Implement the hook; this is for variables not bound to a specific page or user;
 * Implement the 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.
 * Inside the hook handler, there are two ways to add a variable:
 * The "direct" way is calling . 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 . 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  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.

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
 * 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  object, passing in the name of your group.
