* added configuration directive "HUPisRestart"Rainer Gerhards2008-10-235-2/+41
| | | | | ...which enables to configure HUP to be either a full restart or "just" a leightweight way to close open files
* added a setting "$OptimizeForUniprocessor"Rainer Gerhards2008-10-228-3/+42
| | | | | | ...to enable users to turn off pthread_yield calls which are counter-productive on multiprocessor machines (but have been shown to be useful on uniprocessors)

* | | bugfix: (potentially big) memory leak on HUPRainer Gerhards2008-10-211-13/+32

* | | moved bParseHostname and bIsParsed to msgFlagsRainer Gerhards2008-10-096-6/+19
| | | | | | | | | | | | | | | | | | This enables us to use more efficient calling conventions and also helps us keep the on-disk structure of a msg object more consistent in future releases.

* | | added experimental pthread_yield()Rainer Gerhards2008-10-091-0/+5
| | | | | | | | | | | | | | | which so far seems to increase performance. There is also reason for it to do so, see http://kb.monitorware.com/post14216.html#p14216

* | | reordered imudp processing.Rainer Gerhards2008-10-087-8/+354
| | | | | | | | | | | | | | | | | | Message parsing is now done as part of main message queue worker processing (was part of the input thread) This should also improve performance, as potentially more work is done in parallel.
* | | restructured imudp receive loopRainer Gerhards2008-10-081-0/+1
| | | | | | | | | | | | | | | | | | | | | | | | cleaned up previous code and redid it in a way that makes it much easier to extend it also added a new macro DBGPRINTF which is a performance-optimzed version of dbgprintf

| | |
* | | "output" timestamp now taken from mesg's time generatedRainer Gerhards2008-10-075-11/+29
| | | | | | | | | | | | | | | | | | | | | This enhances performance and, as some have pointed out, is probably also more consistent with what users expect how the various output-timestamp related function should work. This commit needs some more testing.
* | | slightly improved lock contention situation by moving out ofRainer Gerhards2008-10-071-3/+9
| | | | | | | | | | | | the critical section what could so with acceptable consequences
* | | added $UDPServerTimeRequery optionRainer Gerhards2008-10-062-16/+60
| | | | | | | | | | | | | | | | | | | | | ...which enables to work with less acurate timestamps in favor of performance. This enables querying of the time only every n-th time if imudp is running in the tight receive loop (aka receiving messsages at a high rate)

| | | | | | | | | | | | | | | if that timestamp did not contain any subsecond information (the resulting string was garbagge but should have been "0", what it now is).
| * | consolidated time calls during msg object creationRainer Gerhards2008-10-021-0/+9
| | | | | | | | | | | | | | | | | | ...this improves performance and consistency and also fixes a bug where subsecond time properties generated by imfile, imklog and internal messages could be slightly inconsistent.

| * | | removed no longer needed mutex callsRainer Gerhards2008-10-021-3/+0
| | | | | | | | | | | | | | | | | | | | | | | | problem source is that getnameinfo() is not cancel-safe, not that it is not thread-safe. It is now guarded against cancellation.

| | | | | | | | | | | | | | | | | | | | | There was a wrong order of mutex lock operations. It is hard to believe that really caused problems, but in theory it could and with threading we often see that theory becomes practice if something is only used long enough on a fast enough machine with enough CPUs ;)
