Previous versions could run without + any active workers. This simplifies the code at a very small expense. + See v5 compatibility note document for more in-depth discussion. +- enhance: UDP spoofing supported via new output module omudpspoof + See the omudpspoof documentation for details and samples +- bugfix: message could be truncated after TAG, often when forwarding + This was a result of an internal processing error if maximum field + sizes had been specified in the property replacer. +- bugfix: minor static memory leak while reading configuration + did NOT leak based on message volume +- internal: added ability to terminate input modules not via pthread_cancel + but an alternate approach via pthread_kill. This is somewhat safer as we + do not need to think about the cancel-safeness of all libraries we use. + However, not all inputs can easily supported, so this now is a feature + that can be requested by the input module (the most important ones + request it). +--------------------------------------------------------------------------- +Version 5.1.2 [DEVEL] (rgerhards), 2009-07-08 +- bugfix: properties inputname, fromhost, fromhost-ip, msg were lost when + working with disk queues +- some performance enhancements +- bugfix: abort condition when RecvFrom was not set and message reduction + was on. Happend e.g. with imuxsock. +- added $klogConsoleLogLevel directive which permits to set a new + console log level while rsyslog is active +- some internal code cleanup +--------------------------------------------------------------------------- +Version 5.1.1 [DEVEL] (rgerhards), 2009-07-03 +- bugfix: huge memory leak in queue engine (made rsyslogd unusable in + production). Occured if at least one queue was in direct mode + (the default for action queues) +- imported many performance optimizations from v4-devel (4.5.0) +- bugfix: subtle (and usually irrelevant) issue in timout processing + timeout could be one second too early if nanoseconds wrapped +- set a more sensible timeout for shutdow, now 1.5 seconds to complete + processing (this also removes those cases where the shutdown message + was not written because the termination happened before it) +--------------------------------------------------------------------------- +Version 5.1.0 [DEVEL] (rgerhards), 2009-05-29 + +*********************************** NOTE ********************************** +The v5 versions of rsyslog feature a greatly redesigned queue engine. The +major theme for the v5 release is twofold: + +a) greatly improved performance +b) enable audit-grade processing + +Here, audit-grade processing means that rsyslog, if used together with +audit-grade transports and configured correctly, will never lose messages +that already have been acknowledged, not even in fatal failure cases like +sudden loss of power. + +Note that large parts of rsyslog's important core components have been +restructured to support these design goals. As such, early versions of +the engine will probably be less stable than the v3/v4 engine. + +Also note that the initial versions do not cover all and everything. As +usual, the code will evolve toward the final goal as version numbers +increase. +*********************************** NOTE ********************************** + +- redesigned queue engine so that it supports ultra-reliable operations + This resulted in a rewrite of large parts. The new capability can be + used to build audit-grade systems on the basis of rsyslog. +- added $MainMsgQueueDequeueBatchSize and $ActionQueueDequeueBatchSize + configuration directives +- implemented a new transactional output module interface which provides + superior performance (for databases potentially far superior performance) +- increased ompgsql performance by adapting to new transactional + output module interface +--------------------------------------------------------------------------- Version 4.5.2 [DEVEL] (rgerhards), 2009-07-?? - legacy syslog parser changed so that it now accepts date stamps in wrong case. Some devices seem to create them and I do not see any harm |
