Constructor & Destructor Documentation

◆ __construct()

Wikibase\Repo\EditEntity\MediawikiEditEntity::__construct	(	EntityTitleStoreLookup	$titleLookup,
		EntityRevisionLookup	$entityLookup,
		EntityStore	$entityStore,
		EntityPermissionChecker	$permissionChecker,
		EntityDiffer	$entityDiffer,
		EntityPatcher	$entityPatcher,
		?EntityId	$entityId,
		User	$user,
		EditFilterHookRunner	$editFilterHookRunner,
			$maxSerializedEntitySize,
			$baseRevId = `0`,
			$allowMasterConnection = `true`
	)

Parameters

EntityTitleStoreLookup	$titleLookup
EntityRevisionLookup	$entityLookup
EntityStore	$entityStore
EntityPermissionChecker	$permissionChecker
EntityDiffer	$entityDiffer
EntityPatcher	$entityPatcher
EntityId \| null	$entityId	the ID of the entity being edited. May be null when creating a new entity.
User	$user	the user performing the edit
EditFilterHookRunner	$editFilterHookRunner
int	$maxSerializedEntitySize	the maximal allowed entity size in Kilobytes
int	$baseRevId	the base revision ID for conflict checking. Use 0 to indicate that the current revision should be used as the base revision, effectively disabling conflict detections. true and false will be accepted for backwards compatibility, but both will be treated like 0. Note that the behavior of this class changed so that "late" conflicts that arise between edit conflict detection and database update are always detected, and result in the update to fail.
bool	$allowMasterConnection

Member Function Documentation

◆ attemptSave()

Wikibase\Repo\EditEntity\MediawikiEditEntity::attemptSave	(	EntityDocument	$newEntity,
			$summary,
			$flags,
			$token,
			$watch = `null`,
		array	$tags = `[]`
	)

Attempts to save the given Entity object.

This method performs entity level permission checks, checks the edit toke, enforces rate limits, resolves edit conflicts, and updates user watchlists if appropriate.

Success or failure are reported via the Status object returned by this method.

Parameters

EntityDocument	$newEntity
string	$summary	The edit summary.
int	$flags	The EDIT_XXX flags as used by WikiPage::doEditContent(). Additionally, the EntityContent::EDIT_XXX constants can be used.
string \| bool	$token	Edit token to check, or false to disable the token check. Null will fail the token text, as will the empty string.
bool \| null	$watch	Whether the user wants to watch the entity. Set to null to apply default according to getWatchDefault().
string[]	$tags	Change tags to add to the edit. Callers are responsible for checking that the user is permitted to add these tags (typically using `ChangeTags::canAddTagsAccompanyingChange`).

Returns: Status

Exceptions

MWException
ReadOnlyError

Exceptions

ReadOnlyError

◆ entityTypeIsReadOnly()

Wikibase\Repo\EditEntity\MediawikiEditEntity::entityTypeIsReadOnly ( EntityDocument $entity )

private

Parameters

EntityDocument $entity

Returns: bool

◆ fixEditConflict()

Wikibase\Repo\EditEntity\MediawikiEditEntity::fixEditConflict ( EntityDocument $newEntity )

private

Attempts to fix an edit conflict by patching the intended change into the latest revision after checking for conflicts.

Parameters

Exceptions

MWException

Returns: null|EntityDocument The patched Entity, or null if patching failed.

◆ getBaseRevision()

Wikibase\Repo\EditEntity\MediawikiEditEntity::getBaseRevision ( )

Return the base revision for the edit.

If no base revision ID was supplied to the constructor, this returns the latest revision. If the entity does not exist yet, this returns null.

Returns: EntityRevision|null

Exceptions

MWException

Implements Wikibase\Repo\EditEntity\EditEntity.

◆ getBaseRevisionId()

Wikibase\Repo\EditEntity\MediawikiEditEntity::getBaseRevisionId ( )

private

Return the ID of the base revision for the edit.

If no base revision ID was supplied to the constructor, this returns the ID of the latest revision. If the entity does not exist yet, this returns 0.

Returns: int

◆ getDesiredWatchState()

Wikibase\Repo\EditEntity\MediawikiEditEntity::getDesiredWatchState ( $watch )

private

Resolve user specific default default for watch state, if $watch is null.

Parameters

boolean | null $watch

Returns: bool

◆ getEntityId()

Wikibase\Repo\EditEntity\MediawikiEditEntity::getEntityId ( )

Returns the ID of the entity being edited.

May be null if a new entity is to be created.

Returns: null|EntityId

Implements Wikibase\Repo\EditEntity\EditEntity.

◆ getLatestRevision()

Wikibase\Repo\EditEntity\MediawikiEditEntity::getLatestRevision ( )

Returns the latest revision of the entity.

Returns: EntityRevision|null

Implements Wikibase\Repo\EditEntity\EditEntity.

◆ getLatestRevisionId()

private

Returns: int 0 if the entity doesn't exist

◆ getReplicaMode()

Wikibase\Repo\EditEntity\MediawikiEditEntity::getReplicaMode ( )

private

Returns: string

◆ getStatus()

Wikibase\Repo\EditEntity\MediawikiEditEntity::getStatus ( )

Get the status object.

Only defined after attemptSave() was called.

After a successful save, the Status object's value field will contain an array, just like the status returned by WikiPage::doEditContent(). Well known fields in the status value are:

new: bool whether the edit created a new page
revision: Revision the new revision object
errorFlags: bit field indicating errors, see the XXX_ERROR constants.

Returns: Status

Implements Wikibase\Repo\EditEntity\EditEntity.

◆ getTitle()

Wikibase\Repo\EditEntity\MediawikiEditEntity::getTitle ( )

private

Returns the Title of the page holding the entity that is being edited.

Returns: Title|null

◆ getWatchDefault()

Wikibase\Repo\EditEntity\MediawikiEditEntity::getWatchDefault ( )

private

Returns whether the present edit would, per default, lead to the user watching the page.

This uses the user's watchdefault and watchcreations settings and considers whether the entity is already watched by the user.

Note: Keep in sync with logic in EditPage!

Returns: bool

◆ hasEditConflict()

Wikibase\Repo\EditEntity\MediawikiEditEntity::hasEditConflict ( )

Determines whether an edit conflict exists, that is, whether another user has edited the same item after the base revision was created.

In other words, this method checks whether the base revision (as provided to the constructor) is still current. If no base revision was provided to the constructor, this will always return false.

If the base revision is different from the current revision, this will return true even if the edit conflict is resolvable. Indeed, it is used to determine whether conflict resolution should be attempted.

Returns: bool

Implements Wikibase\Repo\EditEntity\EditEntity.

◆ hasError()

Wikibase\Repo\EditEntity\MediawikiEditEntity::hasError ( $errorType = EditEntity::ANY_ERROR )

Checks whether this EditEntity encountered any of the given error types while executing attemptSave().

Parameters

int $errorType bit field using the EditEntity::XXX_ERROR constants. Defaults to EditEntity::ANY_ERROR.

Returns: bool true if this EditEntity encountered any of the error types in $errorType, false otherwise.

Implements Wikibase\Repo\EditEntity\EditEntity.

◆ isNew()

Wikibase\Repo\EditEntity\MediawikiEditEntity::isNew ( )

private

Is the entity new?

Returns: bool

◆ isNewPage()

Wikibase\Repo\EditEntity\MediawikiEditEntity::isNewPage ( )

private

Does this entity belong to a new page? (An entity may be new, and yet not belong to a new page, e.

 g. if it is stored in a non-main slot.)

Returns: bool

◆ isSuccess()

Wikibase\Repo\EditEntity\MediawikiEditEntity::isSuccess ( )

Determines whether the last call to attemptSave was successful.

Returns: bool false if attemptSave() failed, true otherwise

Implements Wikibase\Repo\EditEntity\EditEntity.

◆ isTokenOK()

Wikibase\Repo\EditEntity\MediawikiEditEntity::isTokenOK ( $token )

Make sure the given WebRequest contains a valid edit token.

Parameters

string $token The token to check.

Returns: bool true if the token is valid

Implements Wikibase\Repo\EditEntity\EditEntity.

◆ updateWatchlist()

Wikibase\Repo\EditEntity\MediawikiEditEntity::updateWatchlist ( $watch )

private

Watches or unwatches the entity.

Note: Keep in sync with logic in EditPage!

Todo:: move to separate service

Parameters

bool $watch whether to watch or unwatch the page.

Exceptions

MWException

◆ userWasLastToEdit()

Wikibase\Repo\EditEntity\MediawikiEditEntity::userWasLastToEdit	(	User	$user = `null`,
		EntityId	$entityId = `null`,
			$lastRevId = `false`
	)

private

Check if no edits were made by other users since the given revision.

This makes the assumption that revision ids are monotonically increasing.

Parameters

User \| null	$user
EntityId \| null	$entityId
int \| bool	$lastRevId

Returns: bool
