Detailed Description

Controller-like object for creating and updating pages by creating new revisions.

PageUpdater instances provide compare-and-swap (CAS) protection against concurrent updates between the time grabParentRevision() is called and saveRevision() inserts a new revision. This allows application logic to safely perform edit conflict resolution using the parent revision's content.

See also: docs/pageupdater.txt for more information.

MCR migration note: this replaces the relevant methods in WikiPage.

Since: 1.32

◆ grabParentRevision()

MediaWiki\Storage\PageUpdater::grabParentRevision ( )

Returns the revision that was the page's current revision when grabParentRevision() was first called.

This revision is the expected parent revision of the update, and will be recorded as the new revision's parent revision (unless no new revision is created because the content was not changed).

This method MUST not be called after saveRevision() was called!

The current revision determined by the first call to this methods effectively acts a compare-and-swap (CAS) token which is checked by saveRevision(), which fails if any concurrent updates created a new revision.

Application code should call this method before applying transformations to the new content that depend on the parent revision, e.g. adding/replacing sections, or resolving conflicts via a 3-way merge. This protects against race conditions triggered by concurrent updates.

See also: DerivedPageDataUpdater::grabCurrentRevision()

Note: The expected parent revision is not to be confused with the logical base revision. The base revision is specified by the client, the parent revision is determined from the database. If base revision and parent revision are not the same, the updates is considered to require edit conflict resolution.

Exceptions

LogicException if called after saveRevision().

Returns: RevisionRecord|null the parent revision, or null of the page does not yet exist.

◆ hasEditConflict()

MediaWiki\Storage\PageUpdater::hasEditConflict ( $expectedParentRevision )

Checks whether this update conflicts with another update performed between the client loading data to prepare an edit, and the client committing the edit.

This is intended to detect user level "edit conflict" when the latest revision known to the client is no longer the current revision when processing the update.

An update expected to create a new page can be checked by setting $expectedParentRevision = 0. Such an update is considered to have a conflict if a current revision exists (that is, the page was created since the edit was initiated on the client).

This method returning true indicates to calling code that edit conflict resolution should be applied before saving any data. It does not prevent the update from being performed, and it should not be confused with a "late" conflict indicated by the "edit-conflict" status. A "late" conflict is a CAS failure caused by an update being performed concurrently between the time grabParentRevision() was called and the time saveRevision() trying to insert the new revision.

Note: A user level edit conflict is not the same as the "edit-conflict" status triggered by a CAS failure. Calling this method establishes the CAS token, it does not check against it: This method calls grabParentRevision(), and thus causes the expected parent revision for the update to be fixed to the page's current revision at this point in time. It acts as a compare-and-swap (CAS) token in that it is guaranteed that saveRevision() will fail with the "edit-conflict" status if the current revision of the page changes after hasEditConflict() (or grabParentRevision()) was called and before saveRevision() could insert a new revision.

See also: grabParentRevision()

Parameters

int $expectedParentRevision The ID of the revision the client expects to be the current one. Use 0 to indicate that the page is expected to not yet exist.

Returns: bool

Definition at line 290 of file PageUpdater.php.

References $parent, and MediaWiki\Storage\PageUpdater\grabParentRevision().

◆ inheritSlot()

MediaWiki\Storage\PageUpdater::inheritSlot ( SlotRecord $originalSlot )

Explicitly inherit a slot from some earlier revision.

The primary use case for this is rollbacks, when slots are to be inherited from the rollback target, overriding the content from the parent revision (which is the revision being rolled back).

This should typically not be used to inherit slots from the parent revision, which happens implicitly. Using this method causes the given slot to be treated as "modified" during revision creation, even if it has the same content as in the parent revision.

Parameters

SlotRecord $originalSlot A slot already existing in the database, to be inherited by the new revision.

Definition at line 379 of file PageUpdater.php.

References Revision\SlotRecord\newInherited().

◆ isNew()

MediaWiki\Storage\PageUpdater::isNew ( )

Whether saveRevision() was called and created a new page.

Returns: bool

Definition at line 827 of file PageUpdater.php.

◆ isUnchanged()

MediaWiki\Storage\PageUpdater::isUnchanged ( )

Whether saveRevision() did not create a revision because the content didn't change (null-edit).

Whether the content changed or not is determined by DerivedPageDataUpdater::isChange().

Returns: bool

Definition at line 838 of file PageUpdater.php.

◆ makeAutoSummary()

MediaWiki\Storage\PageUpdater::makeAutoSummary ( $flags )

private

Parameters

int $flags Bit mask: a bit mask of EDIT_XXX flags.

Returns: CommentStoreComment

◆ makeNewRevision()

MediaWiki\Storage\PageUpdater::makeNewRevision	(	CommentStoreComment	$comment,
		User	$user,
			$flags,
		Status	$status
	)

private

Constructs a MutableRevisionRecord based on the Content prepared by the DerivedPageDataUpdater.

This takes care of inheriting slots, updating slots with PST applied, and removing discontinued slots.

This calls Content::prepareSave() to verify that the slot content can be saved. The $status parameter is updated with any errors or warnings found by Content::prepareSave().

Parameters

CommentStoreComment	$comment
User	$user
int	$flags
Status	$status

Returns: MutableRevisionRecord

◆ removeSlot()

MediaWiki\Storage\PageUpdater::removeSlot ( $role )

Removes the slot with the given role.

This discontinues the "stream" of slots with this role on the page, preventing the new revision, and any subsequent revisions, from inheriting the slot with this role.

Parameters

string $role A slot role name (but not "main")

Definition at line 397 of file PageUpdater.php.

References MediaWiki\Storage\PageUpdater\ensureRoleNotRequired().

◆ saveRevision()

MediaWiki\Storage\PageUpdater::saveRevision	(	CommentStoreComment	$summary,
			$flags = `0`
	)

Change an existing article or create a new article.

Updates RC and all necessary caches, optionally via the deferred update array. This does not check user permissions.

It is guaranteed that saveRevision() will fail if the current revision of the page changes after grabParentRevision() was called and before saveRevision() can insert a new revision, as per the CAS mechanism described above.

The caller is however responsible for calling hasEditConflict() to detect a user-level edit conflict, and to adjust the content of the new revision accordingly, e.g. by using a 3-way-merge.

MCR migration note: this replaces WikiPage::doEditContent. Callers that change to using saveRevision() now need to check the "minoredit" themselves before using EDIT_MINOR.

Parameters

CommentStoreComment	$summary	Edit summary
int	$flags	Bitfield: EDIT_NEW Create a new page, or fail with "edit-already-exists" if the page exists. EDIT_UPDATE Create a new revision, or fail with "edit-gone-missing" if the page does not exist. EDIT_MINOR Mark this revision as minor EDIT_SUPPRESS_RC Do not log the change in recentchanges EDIT_FORCE_BOT Mark the revision as automated ("bot edit") EDIT_AUTOSUMMARY Fill in blank summaries with generated text where possible EDIT_INTERNAL Signal that the page retrieve/save cycle happened entirely in this request.

If neither EDIT_NEW nor EDIT_UPDATE is specified, the expected state is detected automatically via grabParentRevision(). In this case, the "edit-already-exists" or "edit-gone-missing" errors may still be triggered due to race conditions, if the page was unexpectedly created or deleted while revision creation is in progress. This can be viewed as part of the CAS mechanism described above.

Returns: RevisionRecord|null The new revision, or null if no new revision was created due to a failure or a null-edit. Use isUnchanged(), wasSuccessful() and getStatus() to determine the outcome of the revision creation.

MWException
RuntimeException
