Detailed Description

Maintain logfile related options.

Note
A Singleton using a Singleton implementation class, that's why there is no _pimpl like in other classes.

Member Typedef Documentation

◆ LineWriter

Constructor & Destructor Documentation

◆ LogControl()

zypp::base::LogControl::LogControl ( )
inlineprivate

Default ctor: Singleton.

Definition at line 205 of file LogControl.h.

Member Function Documentation

◆ instance()

static LogControl zypp::base::LogControl::instance ( )
inlinestatic

Singleton access.

Definition at line 102 of file LogControl.h.

◆ setLineFormater()

void zypp::base::LogControl::setLineFormater ( const shared_ptr< LineFormater > &  formater_r)

Assign a LineFormater.

If you want to format loglines by yourself. NULL installs the default formater.

Definition at line 846 of file LogControl.cc.

◆ logfile() [1/2]

void zypp::base::LogControl::logfile ( const Pathname logfile_r)

Set path for the logfile.

Permission for logfiles is set to 0640 unless an explicit mode_t value is given. An empty pathname turns off logging. "-" logs to std::err.

Exceptions
iflogfile_r is not usable.

Definition at line 811 of file LogControl.cc.

◆ logfile() [2/2]

void zypp::base::LogControl::logfile ( const Pathname logfile_r,
mode_t  mode_r 
)

Definition at line 820 of file LogControl.cc.

◆ logNothing()

void zypp::base::LogControl::logNothing ( )

Turn off logging.

Definition at line 854 of file LogControl.cc.

◆ logToStdErr()

void zypp::base::LogControl::logToStdErr ( )

Log to std::err.

Definition at line 862 of file LogControl.cc.

◆ emergencyShutdown()

void zypp::base::LogControl::emergencyShutdown ( )

will cause the log thread to exit and flush all sockets

Definition at line 870 of file LogControl.cc.

◆ notifyFork()

void zypp::base::LogControl::notifyFork ( )
static

This will completely disable logging.

It is supposed to be called in the child process after fork() was called to shut down all logging completely.

Definition at line 875 of file LogControl.cc.

◆ getLineWriter()

shared_ptr< LogControl::LineWriter > zypp::base::LogControl::getLineWriter ( ) const

Get the current LineWriter.

Definition at line 829 of file LogControl.cc.

◆ setLineWriter()

void zypp::base::LogControl::setLineWriter ( const shared_ptr< LineWriter > &  writer_r)

Assign a LineWriter.

If you want to log the (formated) loglines by yourself. NULL turns off logging (same as logNothing)
