It is recommended to drain queues with the previous +version before switching to this one. +********************************* WARNING ********************************* + +- greatly enhanced performance when compared to v3. +- added configuration directive "HUPisRestart" which enables to configure + HUP to be either a full restart or "just" a leightweight way to + close open files. +- added a setting "$OptimizeForUniprocessor" 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) +- reordered imudp processing. 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. +- bugfix: compressed syslog messages could be slightly mis-uncompressed + if the last byte of the compressed record was a NUL +- added $UDPServerTimeRequery option 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) +- doc bugfix: queue doc had wrong parameter name for setting controlling + worker thread shutdown period +- restructured rsyslog.conf documentation +--------------------------------------------------------------------------- Version 3.21.6 [DEVEL] (rgerhards), 2008-10-22 - consolidated time calls during msg object creation, improves performance and consistency - bugfix: solved a segfault condition - bugfix: subsecond time properties generated by imfile, imklog and internal messages could be slightly inconsistent +- bugfix: (potentially big) memory leak on HUP if queues could not be + drained before timeout - thanks to David Lang for pointing this out - added capability to support multiple module search pathes. Thank to Marius Tomaschewski for providing the patch. - bugfix: im3195 did no longer compile |
