Constructor & Destructor Documentation

◆ __construct()

CirrusSearch\ElasticsearchIntermediary::__construct	(	Connection	$connection,
		UserIdentity	$user = null,
			$slowSeconds = null,
			$extraBackendLatency = 0 )

protected

Parameters

Connection	$connection
UserIdentity \| null	$user	user for which this search is being performed. Attached to slow request logs. Note that null isn't for anonymous users those are still User objects and should be provided if possible. Null is for when the action is being performed in some context where the user that caused it isn't available. Like when an action is being performed during a job.
float \| null	$slowSeconds	how many seconds a request through this intermediary needs to take before it counts as slow. 0 means none count as slow. Defaults to CirrusSearchSlowSearch config option.
int	$extraBackendLatency	artificial backend latency.

Member Function Documentation

◆ appendLastLogPayload()

static CirrusSearch\ElasticsearchIntermediary::appendLastLogPayload	(		$key,
			$value )

static

Parameters

string	$key
string	$value

◆ appendMetrics()

CirrusSearch\ElasticsearchIntermediary::appendMetrics ( SearchMetricsProvider $provider )

protected

Parameters

SearchMetricsProvider $provider

◆ failure()

CirrusSearch\ElasticsearchIntermediary::failure	(	ExceptionInterface	$exception = null,
		Connection	$connection = null )

Log a failure and return an appropriate status.

Public so it can be called from pool counter methods.

Parameters

ExceptionInterface \| null	$exception	if the request failed
Connection \| null	$connection	The connection that the failed request was performed against. Will use $this->connection when not provided.

Returns: Status representing a backend failure

◆ getClientTimeout()

CirrusSearch\ElasticsearchIntermediary::getClientTimeout ( $searchType = 'default' )

protected

Parameters

string $searchType

Returns: int the client side timeout

◆ getQueryTypesUsed()

static CirrusSearch\ElasticsearchIntermediary::getQueryTypesUsed ( )

static

Report the types of queries that were issued within the current request.

Returns: string[]

◆ getSearchMetrics()

CirrusSearch\ElasticsearchIntermediary::getSearchMetrics ( )

Get the search metrics we have.

Returns: array

◆ getTimeout()

CirrusSearch\ElasticsearchIntermediary::getTimeout ( $searchType = 'default' )

protected

Parameters

string $searchType

Returns: string search retrieval timeout

◆ hasQueryLogs()

static CirrusSearch\ElasticsearchIntermediary::hasQueryLogs ( )

static

Returns: bool True when query logs have been generated by the current php execution.

◆ isMSearchResultSetOK()

static CirrusSearch\ElasticsearchIntermediary::isMSearchResultSetOK ( MultiResultSet $multiResultSet )

static

check validity of the multisearch response

Parameters

MultiResultSet $multiResultSet

Returns: bool

◆ newLog()

CirrusSearch\ElasticsearchIntermediary::newLog	(		$description,
			$queryType,
		array	$extra = [] )

abstractprotected

Parameters

string	$description	A psr-3 compliant string describing the request
string	$queryType	The type of search being performed such as fulltext, get, etc.
array	$extra	A map of additional request-specific data

Returns: RequestLog

Reimplemented in CirrusSearch\BuildDocument\RedirectsAndIncomingLinks, CirrusSearch\CompletionSuggester, CirrusSearch\DataSender, CirrusSearch\Searcher, CirrusSearch\Updater, and CirrusSearch\Version.

◆ runMSearch()

CirrusSearch\ElasticsearchIntermediary::runMSearch	(	Search	$search,
		RequestLog	$log,
		Connection	$connection = null,
		callable	$resultsTransformer = null )

protected

Parameters

Search	$search
RequestLog	$log
Connection \| null	$connection
callable \| null	$resultsTransformer	that accepts a Multi/ResultSets

Returns: Status

◆ setResultPages()

static CirrusSearch\ElasticsearchIntermediary::setResultPages ( array $matches )

static

This is set externally because we don't have complete control, from the SearchEngine interface, of what is actually sent to the user.

Instead hooks receive the final results that will be sent to the user and set them here.

Accepts two result sets because some places (Special:Search) perform multiple searches. This can be called multiple times, but only that last call wins. For API's that is correct, for Special:Search a hook catches the final results and sets them here.

Parameters

ISearchResultSet[] $matches

◆ start()

CirrusSearch\ElasticsearchIntermediary::start ( RequestLog $log )

Mark the start of a request to Elasticsearch.

Public so it can be called from pool counter methods.

Parameters

RequestLog $log

◆ startNewLog()

CirrusSearch\ElasticsearchIntermediary::startNewLog	(		$description,
			$queryType,
		array	$extra = [] )

protected

Parameters

string	$description	A psr-3 compliant string describing the request
string	$queryType	The type of search being performed such as fulltext, get, etc.
array	$extra	A map of additional request-specific data

Returns: RequestLog

◆ success()

CirrusSearch\ElasticsearchIntermediary::success	(		$result = null,
		Connection	$connection = null )

Log a successful request and return the provided result in a good Status.

If you don't need the status just ignore the return. Public so it can be called from pool counter methods.

Parameters

mixed \| null	$result	result of the request. defaults to null in case the request doesn't have a result
Connection \| null	$connection	The connection the succesful request was performed against. Will use $this->connection when not provided.

Returns: Status wrapping $result

◆ successViaCache()

CirrusSearch\ElasticsearchIntermediary::successViaCache ( RequestLog $log )

Log a successful request when the response comes from a cache outside elasticsearch.

This is a combination of self::start() and self::success().

Parameters

RequestLog $log
