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 4.5.0 [DEVEL] (rgerhards), 2009-??-?? - activation order of inputs changed, they are now activated only after privileges are dropped. Thanks to Michael Terry for the patch. |
