Member Function Documentation

◆ canProbablyDeleteAssociatedTalk()

MediaWiki\Page\DeletePage::canProbablyDeleteAssociatedTalk ( )

Tests whether it's probably possible to delete the associated talk page.

This checks the replica, so it may not see the latest master change, and is useful e.g. for building the UI.

Returns: StatusValue

Definition at line 258 of file DeletePage.php.

◆ deleteIfAllowed()

MediaWiki\Page\DeletePage::deleteIfAllowed ( string $reason )

Same as deleteUnsafe, but checks permissions.

Parameters

string $reason

Returns: StatusValue

Definition at line 361 of file DeletePage.php.

◆ deleteInternal()

MediaWiki\Page\DeletePage::deleteInternal	(	WikiPage	$page,
		string	$pageRole,
		string	$reason,
		?string	$webRequestId = null )

Access: internal: The only external caller allowed is DeletePageJob. Back-end article deletion

Only invokes batching via the job queue if necessary per DeleteRevisionsBatchSize. Deletions can often be completed inline without involving the job queue.

Potentially called many times per deletion operation for pages with many revisions.

Parameters

WikiPage	$page
string	$pageRole
string	$reason
string \| null	$webRequestId

Returns: Status

Definition at line 529 of file DeletePage.php.

◆ deleteUnsafe()

MediaWiki\Page\DeletePage::deleteUnsafe ( string $reason )

Back-end article deletion: deletes the article with database consistency, writes logs, purges caches.

Note: This method doesn't check user permissions. Use deleteIfAllowed for that.

Parameters

string $reason Delete reason for deletion log

Returns

Status Status object:

If successful (or scheduled), a good Status
If a page couldn't be deleted because it wasn't found, a Status with a non-fatal 'cannotdelete' error.
A fatal Status otherwise.

Definition at line 449 of file DeletePage.php.

◆ deletionsWereScheduled()

MediaWiki\Page\DeletePage::deletionsWereScheduled ( )

Returns: bool[] Whether the deletions were scheduled

Exceptions

BadMethodCallException If no deletions were attempted

Definition at line 350 of file DeletePage.php.

◆ forceImmediate()

MediaWiki\Page\DeletePage::forceImmediate ( bool $forceImmediate )

If false, allows deleting over time via the job queue.

Parameters

bool $forceImmediate

Returns: self For chaining

Definition at line 247 of file DeletePage.php.

◆ getLegacyHookErrors()

MediaWiki\Page\DeletePage::getLegacyHookErrors ( )

Access: internal: BC method for use by WikiPage::doDeleteArticleReal only.

Returns: array|string

Definition at line 194 of file DeletePage.php.

◆ getSuccessfulDeletionsIDs()

MediaWiki\Page\DeletePage::getSuccessfulDeletionsIDs ( )

Returns: int[] Array of log IDs of successful deletions

Exceptions

BadMethodCallException If no deletions were attempted

Definition at line 341 of file DeletePage.php.

◆ isBatchedDelete()

MediaWiki\Page\DeletePage::isBatchedDelete ( int $safetyMargin = 0 )

Determines if this deletion would be batched (executed over time by the job queue) or not (completed in the same request as the delete call).

It is unlikely but possible that an edit from another request could push the page over the batching threshold after this function is called, but before the caller acts upon the return value. Callers must decide for themselves how to deal with this. $safetyMargin is provided as an unreliable but situationally useful help for some common cases.

Parameters

int $safetyMargin Added to the revision count when checking for batching

Returns: bool True if deletion would be batched, false otherwise

Definition at line 422 of file DeletePage.php.

◆ keepLegacyHookErrorsSeparate()

MediaWiki\Page\DeletePage::keepLegacyHookErrorsSeparate ( )

Access: internal: BC method for use by WikiPage::doDeleteArticleReal only.

Returns: self

Definition at line 202 of file DeletePage.php.

◆ setDeleteAssociatedTalk()

MediaWiki\Page\DeletePage::setDeleteAssociatedTalk ( bool $delete )

If set to true and the page has a talk page, delete that one too.

Callers should call canProbablyDeleteAssociatedTalk first to make sure this is a valid operation. Note that the checks here are laxer than those in canProbablyDeleteAssociatedTalk. In particular, this doesn't check whether the page exists as that may be subject to race condition, and it's checked later on (in deleteInternal, using latest data) anyway.

Parameters

bool $delete

Returns: self For chaining

Exceptions

BadMethodCallException If $delete is true and the given page is not a talk page.

Definition at line 283 of file DeletePage.php.

◆ setDeletionAttempted()

MediaWiki\Page\DeletePage::setDeletionAttempted ( )

Called before attempting a deletion, allows the result getters to be used.

Access: internal: The only external caller allowed is DeletePageJob.

Returns: self

Definition at line 316 of file DeletePage.php.

◆ setIsDeletePageUnitTest()

MediaWiki\Page\DeletePage::setIsDeletePageUnitTest ( bool $test )

Access: internal: FIXME: Hack used when running the DeletePage unit test to disable some legacy code.

Parameters

bool $test

Definition at line 304 of file DeletePage.php.

◆ setLogSubtype()

MediaWiki\Page\DeletePage::setLogSubtype ( string $logSubtype )

Set a specific log subtype for the deletion log entry.

Parameters

string $logSubtype

Returns: self For chaining

Definition at line 236 of file DeletePage.php.

◆ setSuppress()

MediaWiki\Page\DeletePage::setSuppress ( bool $suppress )

If true, suppress all revisions and log the deletion in the suppression log instead of the deletion log.

Parameters

bool $suppress

Returns: self For chaining

Definition at line 214 of file DeletePage.php.

◆ setTags()

MediaWiki\Page\DeletePage::setTags ( array $tags )

Change tags to apply to the deletion action.

Parameters

string[] $tags

Returns: self For chaining

Definition at line 225 of file DeletePage.php.
