Todo List
Member ApiUpload::handleStashException ( $e)
Internationalize the exceptions then get rid of this
Class Article

Move and refactor remaining code


Member Article::getRobotPolicy ( $action, ParserOutput $pOutput=null)
actions other than 'view'
Member BackupDumper::backupDb ()
Fixme: the –server parameter is currently not respected, as it doesn't seem terribly easy to ask the load balancer for a particular connection by name.
Class BaseTemplate
Phase this class out and make it an alias for QuickTemplate. Move methods individually as-appropriate either down to QuickTemplate, or (with deprecation) up to SkinTemplate.
Class BitmapMetadataHandler
Other image formats.
Member BitmapMetadataHandler::Tiff ( $filename)
Add XMP support, so this function actually makes sense to put here.
Class BufferingStatsdDataFactory
Evaluate upstream's StatsdService class, which implements similar buffering logic and was released in statsd-php-client 1.0.13, shortly after we implemented this here for statsd-php-client 1.0.12 at the time.
Member CacheTime::isDifferentRevision ( $id)
We always return false if $this->getCacheRevisionId() is null; this prevents invalidating the whole parser cache when this change is deployed. Someday that should probably be changed.
Class ChangesListSpecialPage
Most of the functions here should be protected instead of public.
Member ChangesListSpecialPage::getExtraOptions ( $opts)

Not called by anything in this class (but is in subclasses), should be called by something… doHeader() maybe?

This should handle options returned by getDefaultOptions().

Class ChangeTagsLogItem
Abstract out a base class for this and RevDelLogItem, similar to the RevisionItem class but specifically for log items.
Member Content::getTextForSearchIndex ()

Test that this actually works

Make sure this also works with LuceneSearch / WikiSearch

Member Content::getWikitextForTransclusion ()

Allow native handling, bypassing wikitext representation, like for includable special pages.

Allow transclusion into other content models than Wikitext!

Used in WikiPage and MessageCache to get message text. Not so nice. What should we use instead?!

Member ContentHandler::createDifferenceEngine (IContextSource $context, $old=0, $new=0, $rcid=0, $refreshCache=false, $unhide=false)
This is page-level functionality so it should not belong to ContentHandler. Move it to a better place once one exists (e.g. PageTypeHandler).
Member ContentHandler::getFieldsForSearchIndex (SearchEngine $engine)
Expose title, redirect, namespace, text, source_text, text_bytes field mappings here. (see T142670 and T143409)
Member ContribsPager::formatRow ( $row)
This would probably look a lot nicer in a table.
Member Cookie::validateCookieDomain ( $domain, $originDomain=null)

fixme fails to detect 3-letter top-level domains

fixme fails to detect 2-letter top-level domains for single-domain use (probably not a big problem in practice, but there are test cases)

Member CoreTagHooks::gallery (?string $content, array $attributes, Parser $parser)
break Parser::renderImageGallery out here too.
Member DBLockManager::getLocksOnServer ( $lockSrv, array $pathsByType)
change this code to work in one batch
Member DBSiteStore::__construct (ILoadBalancer $dbLoadBalancer)
inject some kind of connection manager that is aware of the target wiki, instead of injecting a LoadBalancer.
Member DeleteAction::runExecuteChecks ()
Should use Action::checkCanExecute instead
Member DeletedContribsPager::formatRow ( $row)
This would probably look a lot nicer in a table.
File deleteOrphanedRevisions.php
More efficient cleanup of text records
Member Diff::__construct ( $from_lines, $to_lines)
Don't do work in the constructor, use a service to create diffs instead (T257472).
Class DifferenceEngine
This class is huge and poorly defined. It should be split into a controller responsible for interpreting query parameters, retrieving data and checking permissions; and a HTML renderer.
Class DiffFormatter


File dumpMessages.php
Make this more useful, right now just dumps content language
Member EditPage::internalAttemptSave (&$result, $markAsBot=false, $markAsMinor=false)
FIXME: This interface is TERRIBLE, but hard to get rid of due to various error display idiosyncrasies. There are also lots of cases where error metadata is set in the object and retrieved later instead of being returned, e.g. AS_CONTENT_TOO_BIG and AS_BLOCKED_PAGE_FOR_USER. All that stuff needs to be cleaned up some time.
Member EnhancedChangesList::makeCacheGroupingKey (RCCacheEntry $cacheEntry)
use rc_source to group, if set; fallback to rc_type
Class EraseArchivedFile
Maybe add some simple logging
Member Exif::__construct ( $file, $byteOrder='')
FIXME: The following are broke: SubjectArea. Need to test the more obscure tags. DigitalZoomRatio = 0/0 is rejected. need to determine if that's valid. Possibly should treat 0/0 = 0. need to read exif spec on that.
Member ExifBitmapHandler::getRotationForExifFromOrientation ( $orientation)
FIXME: Orientation can include flipping as well; see if this is an issue!
Member ExtensionProcessor::extractConfig1 (array $info)
In the future, this should be done via Config interfaces
Member ExtensionProcessor::extractConfig2 (array $info, $dir)
In the future, this should be done via Config interfaces
Member FileRepo::$name
make protected
Class FormOptions
This badly needs some examples and tests :) The usage in SpecialRecentchanges class is a good ersatz in the meantime.
Member GIFHandler::getImageArea ( $image)
Add unit tests
Member HTMLForm::displaySection ( $fields, $sectionName='', $fieldsetIDPrefix='', &$hasUserVisibleFields=false)
Member HTMLForm::setMessagePrefix ( $p)
Currently only used for the "<fieldset>" legend on forms with multiple sections; should be used elsewhere?
Member HTMLForm::setSubmitID ( $t)
FIXME: Integrity of $t is not validated
Member HTMLFormField::isSubmitAttempt (WebRequest $request)
Consider moving this to HTMLForm?
Class HTMLSelectAndOtherField
FIXME: If made 'required', only the text field should be compulsory.
Member Http::isValidURI ( $uri)
FIXME this is wildly inaccurate and fails to actually check most stuff
Class HttpStatus
File IEContentAnalyzer.php
Define the exact license of this file.
Member ImagePage::makeMetadataTable ( $metadata)
FIXME: Bad interface, see note on MediaHandler::formatMetadata().
Class JavaScriptContentHandler
Create a ScriptContentHandler base class, do highlighting stuff there?
Member Language::convertHtml ( $text)
this should get integrated somewhere sensible
Member Language::sprintfDate ( $format, $ts, DateTimeZone $zone=null, &$ttl='unused')
handling of "o" format character for Iranian, Hebrew, Hijri & Thai?
Member Language::translateBlockExpiry ( $str, UserIdentity $user=null, $now=0)
Maybe translate block durations.
Member LanguageYue::segmentByWord ( $string)
FIXME: Only do this for Han characters...
Member LanguageZh_hans::segmentByWord ( $string)
FIXME: Only do this for Han characters...
Class Linker
turn this into a legacy interface for HtmlPageLinkRenderer and similar services.
Member Linker::buildRollbackLink (RevisionRecord $revRecord, IContextSource $context=null, $editCount=false)
Unused outside of this file - should it be made private?
Member Linker::getRollbackEditCount (RevisionRecord $revRecord, $verify)
Unused outside of this file - should it be made private?
Member Linker::makeMediaLinkFile (LinkTarget $title, $file, $html='')
Handle invalid or missing images better.
Class LinkFilter
implement the filter. Currently these are just some functions to help maintenance/cleanupSpam.php remove links to a single specified domain. The next thing is to implement functions for checking a given page against a big list of domains.
File mcc.php


Member MediaHandler::formatMetadata ( $image, $context=false)
FIXME: This interface is not very flexible.
Member MediaWiki\Block\BlockUser::parseExpiryInput (string $expiry)
strtotime() only accepts English strings. This means the expiry input can only be specified in English.
Member MediaWiki\MainConfigSchema::ExtraNamespaces
Add a note about maintenance/namespaceDupes.php
Member MediaWiki\MainConfigSchema::FooterIcons
Reformat documentation.
Member MediaWiki\MainConfigSchema::TextModelsToParse

Make the ToC suppression configurable by the content model (T313455), not a side effect of inclusion here.

On the long run, it would be nice to put categories etc into a separate structure, or at least parse only the contents of comments in the scripts.

Member MediaWiki\Permissions\PermissionManager::getPermissionErrors ( $action, User $user, LinkTarget $page, $rigor=self::RIGOR_SECURE, $ignoreErrors=[])
FIXME: This does not check throttles (User::pingLimiter()).
Class MediaWiki\Permissions\PermissionStatus
Add compat code for PermissionManager::getPermissionErrors and additional info about user blocks.
Member MediaWiki\Preferences\DefaultPreferencesFactory::profilePreferences (User $user, IContextSource $context, &$defaultPreferences)
Inject user Language instead of using context.
Member MediaWiki\Rest\Handler\ParsoidHandler::assertDomainIsCorrect ( $domain)
Remove this when we no longer need to support the {domain} parameter with backwards compatibility with the parsoid extension.
Member MediaWiki\Revision\RevisionStore::__construct (ILoadBalancer $loadBalancer, SqlBlobStore $blobStore, WANObjectCache $cache, BagOStuff $localCache, CommentStore $commentStore, NameTableStore $contentModelStore, NameTableStore $slotRoleStore, SlotRoleRegistry $slotRoleRegistry, ActorMigration $actorMigration, ActorStore $actorStore, IContentHandlerFactory $contentHandlerFactory, PageStore $pageStore, TitleFactory $titleFactory, HookContainer $hookContainer, $wikiId=WikiAwareEntity::LOCAL)
$blobStore should be allowed to be any BlobStore!
Member MediaWiki\Revision\RevisionStore::getRcIdIfUnpatrolled (RevisionRecord $rev)
This is overly specific, so move or kill this method.
Member MediaWiki\Revision\RevisionStore::getRecentChange (RevisionRecord $rev, $flags=0)
move this somewhere else?
Member MediaWiki\Revision\RevisionStore::newNullRevision (IDatabase $dbw, PageIdentity $page, CommentStoreComment $comment, $minor, UserIdentity $user)
Introduce newFromParentRevision(). newNullRevision can then be based on that (or go away).
Member MediaWiki\Settings\Config\ArrayConfigBuilder::build ()
Once we can use PHP 7.4, change the return type declaration to IterableConfig.
Class MediaWiki\Storage\DerivedPageDataUpdater
Define interfaces for the different use cases of DerivedPageDataUpdater, particularly providing access to post-PST content and ParserOutput to callbacks during revision creation, which currently use WikiPage::prepareContentForEdit, and allowing updates to be triggered on purge, import, and undeletion, which currently use WikiPage::doEditUpdates() and Content::getSecondaryDataUpdates().
Member MediaWiki\Storage\DerivedPageDataUpdater::getRevision ()
This is currently used by PageUpdater::makeNewRevision() to construct an unsaved MutableRevisionRecord instance. Introduce something like an UnsavedRevisionFactory service for that purpose instead!
Member MediaWiki\Storage\DerivedPageDataUpdater::isChange ()
This should probably be fixed.
Member MediaWiki\Storage\SqlBlobStore::compressData (&$blob)
make this private, there should be no need to use this method outside this class.
Member MediaWiki\Storage\SqlBlobStore::decompressData (string $blob, array $blobFlags)
make this private, there should be no need to use this method outside this class.
Member MediaWiki\Storage\SqlBlobStore::expandBlob ( $raw, $flags, $cacheKey=null)
make this private, there should be no need to use this method outside this class.
Member MediaWiki\Utils\UrlUtils::assemble (array $urlParts)
Need to integrate this into expand() (see T34168)
Member MediaWiki\Utils\UrlUtils::expand (string $url, $defaultProto=PROTO_FALLBACK)
this won't work with current-path-relative URLs like "subdir/foo.html", etc.
Member MediaWiki\Utils\UrlUtils::expandIRI (string $url)
handle punycode domains too
Member MediaWiki\Utils\UrlUtils::removeDotSegments (string $urlPath)
Need to integrate this into expand() (see T34168)
Member MediaWikiTitleCodec::splitTitleString ( $text, $defaultNamespace=NS_MAIN)

This method should be split up and an appropriate interface defined for use by the Title class.

this method is only exposed as a temporary measure to ease refactoring. It was copied with minimal changes from Title::secureAndSplit().

Member MergeHistory::merge (Authority $performer, $reason='')
if all versions of page A are moved to B and then a user tries to do a reverse-merge via the "unmerge" log link, then page A will still be a redirect (as it was after the original merge), though it will have the old revisions back from before (as expected). The user may have to "undo" the redirect manually to finish the "unmerge". Maybe this should delete redirects at the source page of merges?
Class Message
  • test, can we have tests?
  • this documentation needs to be extended
Member Message::isBlank ()
FIXME: Merge with isDisabled()?
Member MimeAnalyzer::getMediaType (string $path=null, string $mime=null)

analyse file if need be

look at multiple extension, separately and together.

Member MimeAnalyzer::isRecognizableExtension (string $extension)
Be more accurate when using fancy MIME detector plugins; right now this is the bare minimum getimagesize() list.
File mwdocgen.php
Member MWException::getHTML ()
Rarely used, remove in favour of generic MWExceptionRenderer
Member MWException::getText ()
Rarely used, remove in favour of generic MWExceptionRenderer
Member MWHttpRequest::isValidURI ( $uri)
FIXME this is wildly inaccurate and fails to actually check most stuff
Member MWHttpRequest::setData (array $args)
overload the args param
Class OutputPage


FIXME: Another class handles sending the whole page to the client.

Member OutputPage::disallowUserJs ()
this should be given a more accurate name
Member PageArchive::listFiles ()
Does this belong in Image for fuller encapsulation?
Member Parser\ParserCacheMetadata::getCacheTime ()
remove legacy -1
Class Parser\Parsoid\Config\PageConfig
We should probably deprecate ParserOptions somehow, using a version of this directly instead.
Member Parser\Parsoid\HTMLTransform::getOriginalHtml ()
Make this method redundant, nothing should operate on HTML strings.
Class Preprocessor_Hash
: Consider replacing descriptor arrays with objects of a new class. Benchmark and measure resulting memory impact.
Member PurgeChangedPages::pageableSortedRows (IResultWrapper $res, $column, $limit)
move this elsewhere
File rebuildrecentchanges.php
File rebuildtextindex.php
Class RecentChange
Deprecate access to mAttribs (direct or via getAttributes). Right now we're having to include both rc_comment and rc_comment_text/rc_comment_data so random crap works right.
Member RevisionItem::getDiffLink ()
Essentially a copy of RevDelRevisionItem::getDiffLink. That class should inherit from this one, and implement an appropriate interface instead of extending RevDelItem
Member RevisionItem::getHTML ()
Essentially a copy of RevDelRevisionItem::getHTML.
Member RevisionItem::getRevisionLink ()
Essentially a copy of RevDelRevisionItem::getRevisionLink. That class should inherit from this one, and implement an appropriate interface instead of extending RevDelItem
Member Sanitizer::escapeClass ( $class)
For extra validity, input should be validated UTF-8.
Member Sanitizer::mergeAttributes ( $a, $b)
implement merging for other attributes such as style
Member Sanitizer::validateAttributes ( $attribs, $allowed)

Check for legal values where the DTD limits things.

Check for unique id attribute :P

Member Sanitizer::validateTagAttributes ( $attribs, $element)

Check for legal values where the DTD limits things.

Check for unique id attribute :P

Member SearchEngine::getTextFromContent (Title $t, Content $c=null)
This isn't ideal, we'd really like to have content-specific handling here
Class SearchEngineDummy

FIXME: Dummy class should probably try something at least mildly useful, such as a LIKE search through titles.

Class SpecialAllPages
Rewrite using IndexPager
Member SpecialBlock::getSuggestedDurations (Language $lang=null, $includeOther=true)
FIXME: This uses a rather odd syntax for the options, should it be converted to the standard "**<duration>|<displayname>" format?
Member SpecialContributions::contributionsSub ( $userObj, $targetName)
FIXME: Almost the same as getSubTitle in SpecialDeletedContributions.php. Could be combined.
Member SpecialLinkSearch::getMaxResults ()
FIXME This special page should not use LIMIT for paging
Member SpecialRevisionDelete::addUsageText ()
FIXME: Wikimedia-specific policy text
Member SpecialRevisionDelete::tryShowFile ( $archiveName)
Mostly copied from Special:Undelete. Refactor.
Class SpecialUncategorizedImages
FIXME: Use an instance of UncategorizedPagesPage or something
Class SpecialUncategorizedPages
FIXME: Make $requestedNamespace selectable, unify all subclasses into one
Member SpecialUpload::rotationEnabled ()
What about non-BitmapHandler handled files?
Class StripState
document, briefly.
Class SwiftVirtualRESTService
caching support (APC/memcached)
Class TableDiffFormatter
Member TempFSFile::getUsableTempDirectory ()
Is there any useful way to test this? Would it be useful to make this non-static on TempFSFileFactory?
Member Title::getBrokenLinksFrom ()
check if needed (used only in SpecialBrokenRedirects.php, and should use redirect table in this case).
Member Title::getContentModel ( $flags=0)
Deprecate this in favor of SlotRecord::getModel()
Member TitleFormatter::getNamespaceName ( $namespace, $text)
Move this to a separate interface
Member TransformationalImageHandler::getClientScalingThumbnailImage ( $image, $scalerParams)
FIXME: No rotation support
Class UnregisteredLocalFile
Currently it doesn't really work in the repository role, there are lots of functions missing. It is used by the WebStore extension in the standalone role.
File update.php


Member UploadBase::checkSvgScriptCallback ( $element, $attribs, $data=null)
Replace this with a whitelist filter!
Member User::saveSettings ()
Only rarely do all these fields need to be set!
Member WatchAction::getExpiryOptions (MessageLocalizer $msgLocalizer, $watchedItem)
Move this somewhere better when it's being used in more than just this action.
Member wfShowingResults ( $offset, $limit)
Member WikiMap::getWikiName ( $wikiID)
We can give more info than just the wiki id!
Member Wikimedia\Rdbms\DatabasePostgres::doInsertSelectNative ( $destTable, $srcTable, array $varMap, $conds, $fname, array $insertOptions, array $selectOptions, $selectJoinConds)
FIXME: Implement this a little better (separate select/insert)?
Member Wikimedia\Rdbms\Platform\ISQLPlatform::makeWhereFrom2d ( $data, $baseKey, $subKey)
Does this actually belong in the library? It seems overly MW-specific.
Member WikiPage::getActionOverrides ()
Move this UI stuff somewhere else
Member WikiPage::insertOn ( $dbw, $pageId=null)
Factor out into a PageStore service, to be used by PageUpdater.
Member WikiPage::supportsSections ()

The skin should check this and not offer section functionality if sections are not supported.

The EditPage should check this and not offer section functionality if sections are not supported.

Member WikiPage::updateRevisionOn ( $dbw, RevisionRecord $revision, $lastRevision=null, $lastRevIsRedirect=null)
Factor out into a PageStore service, or move into PageUpdater.
Member WikiRevision::$isTemp
Member WordLevelDiff::__construct ( $linesBefore, $linesAfter)
Don't do work in the constructor, use a service to create diffs instead (T257472).
