Detailed Description

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

This logger is configured by the following global configuration variables:

  • $wgDebugLogFile
  • $wgDebugLogGroups
  • $wgDBerrorLog
  • $wgDBerrorLogTZ

See documentation in DefaultSettings.php for detailed explanations of each variable.

Constructor & Destructor Documentation

◆ __construct()

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

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$text
string$fileFilename

◆ 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', 'wfLogDBError' and 'wfErrorLog' channels receive special fomatting 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
