weekend rsyslog work log

Past two day’s rsyslog work log:
2008-01-26
– improved SIGSEGV handler a bit (now we get a core dump)
– partially fixed bug that caused rsyslogd to stall processing enqueued messages
after turning off DA mode and before any new message were arrived (if a new
message arrived, everything went back to normal, so it was a temporary halt)
2008-01-27
– fixed the situation where message processing could be stalled for some period
after DA mode turn off
– reduced number of unnecessary wakeups of DA worker thread when high water mark
is not yet reached
– fixed a cosmetic issue in timeoutValue calculation (just used for displaying)
– fixed a bug when shutting down DA queue
– some more fixing and cleanup on the queue shutdown sequence
– fixed queue termination in case bSaveOnShutdown is 0
– implemented the $MainMsgQueueSaveOnShutdown config directive
– implemented the $MainMsgQueueWorkerThreadMinimumMessages config directive
– implemented the $MainMsgQueueTimeoutWorkerThreadShutdown config directive
