Using Logog for crash analysis

[Joseph Shtok]

Dear John,

I would like to use the Logog in a fashoin that would permit presering (almost) all of the log messages in the case the code crashes. For example, I can keep a buffer and dump it to file once in 500 ms.

I have tried the following code (borrowed in parts from the unitest)

LOGOG_INITIALIZE();

{

LogFile logFile( "log.txt" );

LogBuffer logBuffer( &logFile );

logBuffer.SetNullTerminatesStrings( false );

logFile.UnsubscribeToMultiple( AllFilters() );

Formatter *pFormatter = &GetDefaultFormatter();

pFormatter->SetShowTimeOfDay( true );

ERR( _LG( "This is an error") );

DBUG( _LG( "This is debugging info ",) );

logBuffer.Dump();

WARN("a WARNING MESSAGE WITH number %.3f", 0.43543);

                logBuffer.Dump();

}

LOGOG_SHUTDOWN();

I would expect the logBuffer.Dump(); to save the first two errors to the file, but the file only appears to get filled with content when the whole program finishes. If the program crashes after a the first .Dump(), nothing is saved (I use 'break' in Debug mode to simulate the crash). What happens when the .Dump() is called?

Thank you,

Joseph Shtok

Set the bEnableOutputBuffering parameter on the logFile, when creating it, to false, and Bob's your uncle.

    LogFile logFile("log.txt", false);

I'm updating the test suite and the documentation accordingly.
