addWatch (UserIdentity $user, $target, ?string $expiry=null)

addWatchBatchForUser (UserIdentity $user, array $targets, ?string $expiry=null)

Add multiple items to the user's watchlist.

clearUserWatchedItems (UserIdentity $user)

Deletes ALL watched items for the given user when under $updateRowsPerQuery entries exist.

clearUserWatchedItemsUsingJobQueue (UserIdentity $user)

Queues a job that will clear the users watchlist using the Job Queue.

countExpired ()

Get the number of watchlist items that expire before the current time.

Since: 1.35

Returns: int

Check if the user is temporarily watching the page.

isWatched (UserIdentity $user, $target)

loadWatchedItem (UserIdentity $user, $target)

loadWatchedItemsBatch (UserIdentity $user, array $targets)

maybeEnqueueWatchlistExpiryJob ()

Probabilistically add a job to purge the expired watchlist items, if watchlist expiration is enabled, based on the value of $wgWatchlistPurgeRate.

Since: 1.36

mustClearWatchedItemsUsingJobQueue (UserIdentity $user)

overrideDeferredUpdatesAddCallableUpdateCallback (callable $callback)

Overrides the DeferredUpdates::addCallableUpdate callback This is intended for use while testing and will fail if MW_PHPUNIT_TEST is not defined.

removeExpired (int $limit, bool $deleteOrphans=false)

Remove some number of expired watchlist items.

Since: 1.35

Parameters

int	$limit	The number of items to remove.
bool	$deleteOrphans	Whether to also delete `watchlist_expiry` rows that have no related `watchlist` rows (because not all code knows about the expiry table yet). This runs two extra queries, so is only done from the purgeExpiredWatchlistItems.php maintenance script.

removeWatch (UserIdentity $user, $target)

removeWatchBatchForUser (UserIdentity $user, array $titles)

resetAllNotificationTimestampsForUser (UserIdentity $user, $timestamp=null)

Schedule a DeferredUpdate that sets all of the "last viewed" timestamps for a given user to the same value.

resetNotificationTimestamp (UserIdentity $user, $title, $force='', $oldid=0)

setNotificationTimestampsForUser (UserIdentity $user, $timestamp, array $targets=[])

Set the "last viewed" timestamps for certain titles on a user's watchlist.

◆ addWatch()

WatchedItemStore::addWatch	(	UserIdentity	$user,
			$target,
		?string	$expiry = null )

Since: 1.27 Method added.; 1.35 Accepts $expiry parameter.

Parameters

UserIdentity	$user
LinkTarget \| PageIdentity	$target	deprecated passing LinkTarget since 1.36

UserIdentity	$user
string \| int \| null	$timestamp	Value to set all timestamps to, null to clear them

Implements WatchedItemStoreInterface.

◆ resetNotificationTimestamp()

WatchedItemStore::resetNotificationTimestamp	(	UserIdentity	$user,
			$title,
			$force = '',
			$oldid = 0 )

Since: 1.27

Parameters

UserIdentity	$user
LinkTarget \| PageIdentity	$title	deprecated passing LinkTarget since 1.36
string	$force
int	$oldid

Returns: bool

Implements WatchedItemStoreInterface.

Definition at line 1384 of file WatchedItemStore.php.

◆ setNotificationTimestampsForUser()

WatchedItemStore::setNotificationTimestampsForUser	(	UserIdentity	$user,
			$timestamp,
		array	$targets = [] )

Set the "last viewed" timestamps for certain titles on a user's watchlist.

If the $targets parameter is omitted or set to [], this method simply wraps resetAllNotificationTimestampsForUser(), and in that case you should instead call that method directly; support for omitting $targets is for backwards compatibility.

If $targets is omitted or set to [], timestamps will be updated for every title on the user's watchlist, and this will be done through a DeferredUpdate. If $targets is a non-empty array, only the specified titles will be updated, and this will be done immediately (not deferred).

Since: 1.27

Parameters

UserIdentity	$user
string \| int	$timestamp	Value to set the "last viewed" timestamp to (null to clear)
LinkTarget[]	$targets	Titles to set the timestamp for; [] means the entire watchlist

Returns: bool

Implements WatchedItemStoreInterface.

Definition at line 1198 of file WatchedItemStore.php.

◆ setStatsdDataFactory()

WatchedItemStore::setStatsdDataFactory ( StatsdDataFactoryInterface $stats )

Parameters
