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

Extensions may define additional errors.
$return->value will contain an associative array with members as follows: new: Boolean indicating if the function attempted to create a new article. revision: The revision object for the inserted revision, or null.

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.

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.
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. |
Definition at line 321 of file PageUpdater.php.
References MediaWiki\Storage\PageUpdater\grabParentRevision().
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.
SlotRecord | $originalSlot | A slot already existing in the database, to be inherited by the new revision. |
Definition at line 410 of file PageUpdater.php.
MediaWiki\Storage\PageUpdater::isNew | ( | ) |
Whether saveRevision() was called and created a new page.
Definition at line 865 of file PageUpdater.php.
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().

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().

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. Will do nothing if $oldestRevertedRevId is 0.
int | $revertMethod | The method used to make the revert: REVERT_UNDO, REVERT_ROLLBACK or REVERT_MANUAL |
int | $oldestRevertedRevId | The ID of the oldest revision that was reverted. |
int | $newestRevertedRevId | The ID of the newest revision that was reverted. This parameter is optional, default value is $oldestRevertedRevId |
Definition at line 462 of file PageUpdater.php.
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.
string | $role | A slot role name (but not "main") |

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.
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.
