PrefetchingTermLookup probably wants an implementation that allows composing a service from multiple different parts. This would for example allow MediaInfo to use a default null AliasTermBuffer (as aliases do not exist in that context), while using a LabelLookup etc that looks up from the correct place.

Class Wikibase\Lib\Formatters\CommonsLinkFormatter

Use MediaWiki renderer

Class Wikibase\Lib\Formatters\CommonsThumbnailFormatter

Most feature requests require this to be a SnakFormatter instead of a ValueFormatter

Class Wikibase\Lib\Formatters\DispatchingValueFormatter

Plain format() shouldn't be supported, formatValue() should require the dataType ID.

Class Wikibase\Lib\Formatters\MwTimeIsoFormatter

move me to DataValues-time

Member Wikibase\Lib\Formatters\OutputFormatValueFormatterFactory::applyLanguageDefaults (FormatterOptions $options)

: Sort out how the desired language is specified. We have two language options, each accepting different ways of specifying the language. That's not good.

this shouldn't be public at all. Perhaps factor it out into a helper class.

Member Wikibase\Lib\Formatters\QuantityDetailsFormatter::format ( $value)

Mark "unitless" units somehow, e.g. via CSS or with an appended message.

Display URIs that start with http:// or https:// as clickable links.

Display URIs to entities in the local repository as clickable labels.

Member Wikibase\Lib\Formatters\TypedValueFormatter::formatValue (DataValue $value, $dataTypeId=null)

make $dataTypeId mandatory.

Member Wikibase\Lib\Store\EntityIdLookup::getEntityIdForTitle (Title $title)

Switch this to using TitleValue once we can easily get the content model and handler based on a TitleValue.

Member Wikibase\Lib\Store\EntityStore::isWatching (User $user, EntityId $id)

move this to a separate service

Member Wikibase\Lib\Store\EntityStore::updateWatchlist (User $user, EntityId $id, $watch)

move this to a separate service

Member Wikibase\Lib\Store\EntityTitleLookup::getTitleForId (EntityId $id)

change this to return a TitleValue

Class Wikibase\Lib\Store\HashSiteLinkStore

Should be moved to the tests folder and namespace.

Member Wikibase\Lib\Store\Sql\SiteLinkTable::getItemIdForLink (string $globalSiteId, string $pageTitle)

may want to deprecate this or change it to always return entity id object only

Class Wikibase\Lib\Store\Sql\Terms\CleanTermsIfUnusedJob

Execute the cleanup of each table in its own transaction to further reduce lock contention

Interface Wikibase\Lib\Store\Sql\WikiPageEntityMetaDataAccessor

This whole interface may no longer be needed with the introduction of RevisionRecord which can represent a revision on any wiki. MetaData accessing can probably be killed and instead RevisionRecord just be returned.

Member Wikibase\Lib\StringNormalizer::removeBadCharFirst (string $string)

this was stolen from the Language class. Make that code reusable.

Member Wikibase\Lib\StringNormalizer::removeBadCharLast (string $string)

this was stolen from the Language class. Make that code reusable.

Class Wikibase\Lib\WikibaseSettings

Move this to a separate component.

Member Wikibase\Repo\Api\ResultBuilder::addSiteLinkList (SiteLinkList $siteLinkList, $path, $addUrl=false)

use a SiteLinkListSerializer when created in DataModelSerialization here

Member Wikibase\Repo\Api\SetClaim::getSummary (array $params, Statement $statement, StatementList $statementList)

this summary builder is ugly and summary stuff needs to be refactored

Member Wikibase\Repo\ChangeOp\ChangeOpsMerge::__construct (Item $fromItem, Item $toItem, array $ignoreConflicts, EntityConstraintProvider $constraintProvider, ChangeOpFactoryProvider $changeOpFactoryProvider, SiteLookup $siteLookup, StatementsMerger $statementsMerger)

Injecting ChangeOpFactoryProvider is an Abomination Unto Nuggan, we'll need a MergeChangeOpsSequenceBuilder or some such. This will allow us to merge different kinds of entities nicely, too.

Member Wikibase\Repo\Content\EntityHandler::__construct ( $modelId, $unused, EntityContentDataCodec $contentCodec, EntityConstraintProvider $constraintProvider, ValidatorErrorLocalizer $errorLocalizer, EntityIdParser $entityIdParser, FieldDefinitions $fieldDefinitions, $legacyExportFormatDetector=null)

Get rid of me

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

$flags here should ideally not refer to EDIT_ constants from mediawiki core.

Member Wikibase\Repo\EditEntity\MediaWikiEditEntity::updateWatchlist ( $watch)

move to separate service

Class Wikibase\Repo\GenericEventDispatcher

should go into MediaWiki core.

Member Wikibase\Repo\Hooks\ShowSearchHitHandler::onShowSearchHitTitle (&$title, &$titleSnippet, $result, $terms, $specialSearch, &$query, &$attributes)

Add highlighting when Q##-id matches and not label text.

Member Wikibase\Repo\LinkedData\EntityDataRequestHandler::MINIMUM_MAX_AGE

Hard maximum could be configurable somehow.

Member Wikibase\Repo\Merge\MergeFactory::newMergeOps (Item $fromItem, Item $toItem, array $ignoreConflicts=[])

Injecting ChangeOpFactoryProvider is an Abomination Unto Nuggan, we'll need a ItemMergeChangeOpsSequenceBuilder or some such.

Class Wikibase\Repo\ParserOutput\EntityParserOutputDataUpdaterCollection

have ItemParserOutputDataUpdater, etc. instead.

Class Wikibase\Repo\Parsers\MwTimeIsoParser

move me to DataValues-time

Member Wikibase\Repo\Rdf\RdfBuilder::addEntityMetaData (EntityId $entityId)

extract into MetaDataRdfBuilder

Member Wikibase\Repo\Rdf\RdfBuilder::addEntityRevisionInfo (EntityId $entityId, int $revision, string $timestamp)

extract into MetaDataRdfBuilder

Member Wikibase\Repo\Rdf\TruthyStatementRdfBuilder::addMainSnak (EntityId $entityId, Statement $statement)

share more of this code with FullStatementRdfBuilder

Member Wikibase\Repo\RepoHooks::onSkinTemplateNavigationUniversal (SkinTemplate $skinTemplate, array &$links)

T282549 Consider moving some of this logic into a place where it can be more adequately tested

Class Wikibase\Repo\StatementRankSerializer

this could be moved to DataModelSerialization (in some form)

Member Wikibase\Repo\Store\Sql\WikiPageEntityStore::isWatching (User $user, EntityId $id)

move this to a separate service

Member Wikibase\Repo\Store\Sql\WikiPageEntityStore::saveEntityContent (EntityContent $entityContent, User $user, $summary='', $flags=0, $baseRevId=false, array $tags=[])

Might be able to further optimize handling of prepared edit in WikiPage.

now we use PageUpdater do we still need the 2 clear calls below?

Interface Wikibase\Repo\Store\Store

provide getXXX() methods for getting local pseudo-singletons (shared service objects).

Member Wikibase\Repo\Validators\UrlSchemeValidators::getValidator ( $scheme)

'bitcoin', 'geo', 'magnet', 'news', 'sip', 'sips', 'sms', 'tel', 'urn', 'xmpp'.

protocol relative '//'.
