Log extra messages in case of error #340

Open GoogleCodeExporter opened 9 years ago

GoogleCodeExporter commented 9 years ago
PeerBlock's tracelog functionality should store non-logged (i.e. too-highly 
verbose) messages in e.g. a ringbuffer, so that they can be logged to 
peerblock.log in the case where an error happens.  

We have lots of messages, but don't want to log them by default.  If an error 
condition happens though, all these extra messages can be of much use in 
helping to pinpoint the exact code path leading up to that error.  So we should 
store the last N messages (overwriting the oldest one once our buffer fills 
up), and then if we hit an exception or other detectable error condition we can 
log all the additional messages leading up to that problem.

This should help with troubleshooting problems, and minimize the requirement to 
reproduce the problem with a higher tracelog verbosity level.
