◆ MYTH_IMPLEMENT_VERBOSE

#define MYTH_IMPLEMENT_VERBOSE

Function Documentation

◆ verboseAdd()

void verboseAdd	(	uint64_t	mask,
		QString	name,
		bool	additive,
		QString	helptext
	)

Add a verbose level to the verboseMap.

Done at initialization.

Parameters

mask	verbose mask (VB_*)
name	name of the verbosity level
additive	true if this is to be ORed with other masks. false if is will clear the other bits.
helptext	Descriptive text for –verbose help output

Definition at line 791 of file logging.cpp.

◆ loglevelAdd()

void loglevelAdd	(	int	value,
		QString	name,
		char	shortname
	)

Add a log level to the logLevelMap.

Done at initialization.

Parameters

value	log level enumerated value (LOG_*) - matches syslog levels
name	name of the log level
shortname	one-letter short name for output into logs

Definition at line 811 of file logging.cpp.

◆ verboseInit()

void verboseInit ( void )

Initialize the logging levels and verbose levels.

Definition at line 826 of file logging.cpp.

Referenced by logLevelGet(), logLevelGetName(), resetLogging(), and verboseArgParse().

◆ verboseHelp()

void verboseHelp ( void )

Outputs the Verbose levels and their descriptions (for –verbose help)

Definition at line 851 of file logging.cpp.

Referenced by verboseArgParse().

◆ resetLogging()

void resetLogging ( void )

Intended for use only by the test harness.

Definition at line 111 of file logging.cpp.

◆ LogPrintLine()

void LogPrintLine	(	uint64_t	mask,
		LogLevel_t	level,
		const char *	file,
		int	line,
		const char *	function,
		QString	message
	)

Format and send a log message into the queue.

This is called from the LOG() macro. The intention is minimal blocking of the caller.

Parameters

mask	Verbosity mask of the message (VB_*)
level	Log level of this message (LOG_* - matching syslog levels)
file	Filename of source code logging the message
line	Line number within the source of log message source
function	Function name of the log message source
message	log message

Definition at line 528 of file logging.cpp.

◆ logPropagateCalc()

void logPropagateCalc ( void )

Generate the logPropagateArgs global with the latest logging level, mask, etc to propagate to all of the mythtv programs spawned from this one.

Definition at line 572 of file logging.cpp.

Referenced by MainServer::HandleSetLogLevel(), MainServer::HandleSetVerbose(), and logStart().

◆ logPropagateQuiet()

bool logPropagateQuiet ( void )

Check if we are propagating a "--quiet".

Returns: true if –quiet is being propagated

Definition at line 619 of file logging.cpp.

Referenced by BurnMenu::doBurn(), getFileDetails(), and MythSystemLegacy::SetCommand().

◆ logStart()

void logStart	(	const QString &	logfile,
		bool	progress,
		int	quiet,
		int	facility,
		LogLevel_t	level,
		bool	propagate,
		bool	testHarness
	)

Entry point to start logging for the application.

This will start up all of the threads needed.

Parameters

logfile	Filename of the logfile to create. Empty if no file.
progress	non-zero if progress output will be sent to the console. This squelches all messages less important than LOG_ERR on the console
quiet	quiet level requested (squelches all console output)
facility	Syslog facility to use. -1 to disable syslog output
level	Minimum logging level to put into the logs
propagate	true if the logfile path needs to be propagated to child processes.
testHarness	Should always be false. Set to true when invoked by the testing code.
