Detailed Description

PSR-3 logger that mimics the historic implementation of MediaWiki's former wfErrorLog logging implementation.

This logger is configured by the following global configuration variables:

$wgDebugLogFile
$wgDebugLogGroups
$wgDBerrorLog
$wgDBerrorLogTZ

See docs/Configuration.md for detailed explanations of these settings.

Constructor & Destructor Documentation

◆ __construct()

MediaWiki\Logger\LegacyLogger::__construct ( $channel )

Parameters

string $channel

Definition at line 104 of file LegacyLogger.php.

References MediaWiki\Logger\LegacyLogger\$channel, $wgDBerrorLog, $wgDebugLogFile, $wgDebugLogGroups, $wgDebugRawPage, $wgDebugToolbar, $wgShowDebug, and wfIsDebugRawPage().

Member Function Documentation

◆ destination()

static MediaWiki\Logger\LegacyLogger::destination	(	$channel,
		$message,
		$context )

staticprotected

Select the appropriate log output destination for the given log event.

If the event context contains 'destination'

Parameters

string	$channel
string	$message
array	$context

Returns: string

◆ emit()

static MediaWiki\Logger\LegacyLogger::emit	(		$text,
			$file )

static

Log to a file without getting "file size exceeded" signals.

Can also log to UDP with the syntax udp://host:port/prefix. This will send lines to the specified port, prefixed by the specified prefix and a space.

Parameters

string	$text
string	$file	Filename

◆ flatten()

static MediaWiki\Logger\LegacyLogger::flatten ( $item )

staticprotected

Convert a logging context element to a string suitable for interpolation.

Parameters

mixed $item

Returns: string

◆ format()

static MediaWiki\Logger\LegacyLogger::format	(	$channel,
		$message,
		$context )

static

Format a message.

Messages to the 'wfDebug' and 'wfLogDBError' channels receive special formatting to mimic the historic output of the functions of the same name. All other channel values are formatted based on the historic output of the wfDebugLog() global function.

Parameters

string	$channel
string	$message
array	$context

Returns: string
