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.md for more information.

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

Since: 1.32

Definition at line 432 of file PageUpdater.php.

◆ getWikiPage()

MediaWiki\Storage\PageUpdater::getWikiPage ( )

private

Returns: WikiPage

Definition at line 464 of file PageUpdater.php.

◆ 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 method 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.

Definition at line 536 of file PageUpdater.php.

◆ 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 502 of file PageUpdater.php.

◆ 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.

Returns: $this

Definition at line 582 of file PageUpdater.php.

◆ isChange()

MediaWiki\Storage\PageUpdater::isChange ( )

Whether the prepared edit is a change compared to the previous revision.

Returns: bool

Definition at line 1104 of file PageUpdater.php.

Referenced by EditPage\createTempUser().

◆ isNew()

MediaWiki\Storage\PageUpdater::isNew ( )

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

Returns: bool

Definition at line 1084 of file PageUpdater.php.

◆ isUnchanged()

MediaWiki\Storage\PageUpdater::isUnchanged ( )

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

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

Deprecated:: since 1.38, use wasRevisionCreated() instead.

Returns: bool

Definition at line 1095 of file PageUpdater.php.

◆ makeAutoSummary()

MediaWiki\Storage\PageUpdater::makeAutoSummary ( )

private

Returns: CommentStoreComment

Definition at line 776 of file PageUpdater.php.

References $content, EDIT_AUTOSUMMARY, and CommentStoreComment\newUnsavedComment().

◆ makeNewRevision()

MediaWiki\Storage\PageUpdater::makeNewRevision	(	CommentStoreComment	$comment,
		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
Status	$status

Returns: MutableRevisionRecord

Definition at line 1159 of file PageUpdater.php.

References $content, $title, EDIT_MINOR, getTitle(), StatusValue\merge(), and wfWarn().

◆ markAsRevert()

MediaWiki\Storage\PageUpdater::markAsRevert	(	int	$revertMethod,
		int	$newestRevertedRevId,
		int	$revertAfterRevId = `null`
	)

Marks this edit as a revert and applies relevant information.

Will also cause the PageUpdater to add a relevant change tag when saving the edit.

Parameters

int	$revertMethod	The method used to make the revert: REVERT_UNDO, REVERT_ROLLBACK or REVERT_MANUAL
int	$newestRevertedRevId	the revision ID of the latest reverted revision.
int \| null	$revertAfterRevId	the revision ID after which revisions are being reverted. Defaults to the revision before the $newestRevertedRevId.

Returns: $this

See also: EditResultBuilder::markAsRevert()

Definition at line 634 of file PageUpdater.php.

◆ prepareUpdate()

MediaWiki\Storage\PageUpdater::prepareUpdate ( int $flags = 0 )

Prepare the update.

This sets up the RevisionRecord to be saved.

Since: 1.37

Parameters

int $flags Bitfield, will be combined with flags set via setFlags(). EDIT_FORCE_BOT and EDIT_INTERNAL will bypass the edit stash.

Returns: PreparedUpdate

Definition at line 316 of file PageUpdater.php.

◆ preventChange()

MediaWiki\Storage\PageUpdater::preventChange ( )

Disable new revision creation, throwing an exception if it is attempted.

Returns: $this

Definition at line 1113 of file PageUpdater.php.

Referenced by EditPage\createTempUser().

◆ 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 601 of file PageUpdater.php.

◆ saveRevision()

MediaWiki\Storage\PageUpdater::saveRevision	(	CommentStoreComment	$summary,
		int	$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, will be combined with the flags set via setFlags(). See there for details.

Note: 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 wasRevisionCreated(), wasSuccessful() and getStatus() to determine the outcome of the revision creation.

Exceptions

MWException
RuntimeException

Definition at line 831 of file PageUpdater.php.

References DeferredUpdates\addCallableUpdate(), EDIT_MINOR, EDIT_NEW, EDIT_UPDATE, ContentHandler\getLocalizedName(), StatusValue\newFatal(), StatusValue\newGood(), and wfMessage().

◆ setContent()

MediaWiki\Storage\PageUpdater::setContent	(		$role,
		Content	$content
	)

Set the new content for the given slot role.

Parameters

string	$role	A slot role name (such as "main")
Content	$content

Returns: $this

Definition at line 547 of file PageUpdater.php.

References $content.

◆ setFlags()

MediaWiki\Storage\PageUpdater::setFlags ( int $flags )

Sets any flags to use when performing the update.

Flags passed in subsequent calls to this method as well as calls to prepareUpdate() or saveRevision() are aggregated using bitwise OR.

Known flags:

 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.

Parameters

int $flags Bitfield

Returns: $this

Definition at line 301 of file PageUpdater.php.

References MediaWiki\Storage\PageUpdater\$flags.

◆ setForceEmptyRevision()

MediaWiki\Storage\PageUpdater::setForceEmptyRevision ( bool $forceEmptyRevision )

Set whether null-edits should create a revision.

Enabling this allows the creation of dummy revisions ("null revisions") to mark events such as renaming in the page history.

Callers should typically also call setOriginalRevisionId() to indicate the ID of the revision that is being repeated. That ID can be obtained from grabParentRevision()->getId().

Since: 1.38

Note: this calls $this->setOriginalRevisionId() with the ID of the current revision, starting the CAS bracket by virtue of calling $this->grabParentRevision().; saveRevision() will fail with a LogicException if setForceEmptyRevision( true ) was called and also content was changed via setContent(), removeSlot(), or inheritSlot().

Parameters

bool $forceEmptyRevision

Returns: $this

Definition at line 419 of file PageUpdater.php.

◆ setOriginalRevisionId()

MediaWiki\Storage\PageUpdater::setOriginalRevisionId ( $originalRevId )

Sets the ID of an earlier revision that is being repeated or restored by this update.

The new revision is expected to have the exact same content as the given original revision. This is used with rollbacks and with dummy "null" revisions which are created to record things like page moves. setForceEmptyRevision() calls this implicitly.

Parameters

int | bool $originalRevId The original revision id, or false if no earlier revision is known to be repeated or restored by this update.

Returns: $this

Definition at line 617 of file PageUpdater.php.

◆ setRcPatrolStatus()

MediaWiki\Storage\PageUpdater::setRcPatrolStatus ( $status )

Sets the "patrolled" status of the edit.

Callers should check the "patrol" and "autopatrol" permissions as appropriate.

See also: $wgUseRCPatrol; $wgUseNPPatrol

Parameters

int $status RC patrol status, e.g. RecentChange::PRC_AUTOPATROLLED.

Returns: $this

Definition at line 383 of file PageUpdater.php.

◆ setSlot()

MediaWiki\Storage\PageUpdater::setSlot ( SlotRecord $slot )

Set the new slot for the given slot role.

Parameters

SlotRecord $slot

Returns: $this

Definition at line 560 of file PageUpdater.php.

References MediaWiki\Revision\SlotRecord\getRole().

◆ setUseAutomaticEditSummaries()

Can be used to enable or disable automatic summaries that are applied to certain kinds of changes, like completely blanking a page.

Parameters

bool $useAutomaticEditSummaries

Returns: $this

See also: $wgUseAutomaticEditSummaries

Definition at line 368 of file PageUpdater.php.

◆ setUsePageCreationLog()

◆ updateRevision()

MediaWiki\Storage\PageUpdater::updateRevision ( int $revId = 0 )

Updates derived slots of an existing article.

Does not update RC. Updates all necessary caches, optionally via the deferred update array. This does not check user permissions. Does not do a PST.

Use wasRevisionCreated(), wasSuccessful() and getStatus() to determine the outcome of the revision update.

Parameters

int $revId

Since: 1.36

Definition at line 965 of file PageUpdater.php.

References EDIT_INTERNAL, ContentHandler\getLocalizedName(), StatusValue\newFatal(), StatusValue\newGood(), and wfMessage().

◆ wasCommitted()

MediaWiki\Storage\PageUpdater::wasCommitted ( )

Whether saveRevision() has been called on this instance.

Returns: bool

Definition at line 1036 of file PageUpdater.php.

◆ wasRevisionCreated()

MediaWiki\Storage\PageUpdater::wasRevisionCreated ( )

Whether saveRevision() did create a revision.

This is not the same as wasSuccessful(): when the new content is exactly the same as the old one (DerivedPageDataUpdater::isChange() returns false) and setForceEmptyRevision( true ) is not set, no new revision is created, but the save is considered successful. This behavior constitutes a "null edit".

Since: 1.38

Returns: bool

Definition at line 1128 of file PageUpdater.php.

◆ wasSuccessful()

MediaWiki\Storage\PageUpdater::wasSuccessful ( )

Whether saveRevision() completed successfully.

This is not the same as wasRevisionCreated(): when the new content is exactly the same as the old one (DerivedPageDataUpdater::isChange() returns false) and setForceEmptyRevision( true ) is not set, no new revision is created, but the save is considered successful. This behavior constitutes a "null edit".

Returns: bool
