syslog-ng 3.4.0alpha2 has been released

------------------------------------------------------------------------------ PACKAGE : syslog-ng VERSION : 3.4.0alpha2 SUMMARY : new stable release DATE : May 1, 2012 ------------------------------------------------------------------------------ DESCRIPTION: A new stable version of syslog-ng Open Source Edition (3.4.0alpha2) has been released. For latest fixes in the 3.4.x feature branch you are recommended to upgrade to this version. CHANGES: 3.4.0alpha2 Tue, 01 May 2012 08:59:21 +0200 Features: ========= * Added support for globbing when including files. Now you can use UNIX shell style wildcards in the names of include files and syslog-ng will properly source all matching files. * Allow huge messages. Earlier log messages were limited to 256k in size, with each name-value pair limited at 64k. These limitations were lifted, syslog-ng now uses a 32 bit integer field to hold the size information for both the whole data structure and individual fields. An artificial limit of 256MB is still applied though, but it is trivial to change that in the future, and until then this should suffice. Other changes: ============== * Flow-control logic was changed, instead of enabling flow-control for all branches of a log statement when a single flags(flow-control) was present, only enable it downwards. * Changed json-parser() to encode JSON array members as ${array[0]}, ${array[1]} and so on, instead of using ".index" suffixes. * Fixed Makefile.am files to avoid attempting to compile mongodb and smtp destination drivers when they are disabled. * Fixed --with-json configure option parsing and added --disable-json for consistency with other optional features. * Removed the "dummy" module, which only served as a placeholder when the original "pluginization" happened in 3.2. Bugfixes: ========= * Fixed a segmentation fault, which happened when source or destination objects were defined without any actual drivers. * Fixed a possible crash in config file parsing that happens when parsing a unix-dgram() source driver and file permissions (owner, group, perm) specified. * Fixed a possible crash (double-free) in the value-pairs command line parser used in $(format-json), in case the command line options have syntax errors. * Handle and print template compilation errors properly during configuration parsing. * Fixed some memory leaks in the configuration compilation code introduced in 3.4. Bugfixes backported from 3.3 (matching 3.3.5): ============================================== * Fixed a significant memory leak that occurred when the receiver side of a syslog connection is slower than syslog-ng. The message which we got EAGAIN for got leaked. * Fixed another memory leak that caused the complete queue for socket based destination drivers to be leaked at reload time. * Fixed a memory leak related to handling TLS enabled connections. As connections come and go the TLS context wasn't freed. * Fixed a small memory leak that occurred when worker threads exit (and later start again). * Fixed a deadlock in the SQL destination that occurred when a COMMIT TRANSACTION command failed. * Fixed an abort() which occurred when the retry timer of a suspended destination fired. * Fixed a framing error in RFC5424 destinations. * MongoDB & SQL: fixed a race condition that caused mongodb/sql destinations to hang. * Fixed handling the ENOBUFS error in udp() destinations on FreeBSD and related/derived platforms. Previously ENOBUFS caused syslog-ng to suspend the destination for time_reopen() (which defaults to 60 seconds), but that's excessive. Reading the literature suggests that there are three ways to handle an ENOBUFS: wait for some undetermined amount of time until the interface buffers are presumably emptied, or let the packet be dropped or go back to the poll loop and hope that by the next time the event is dispatched ENOBUFS will be gone. Right now, syslog-ng will drop the affected packet, as the other two could cause other tasks to starve (wait some time) OR syslog-ng to use 100% CPU. Credits: ======== syslog-ng is developed as a community project, and as such it relies on volunteers to do the work necessarily to produce syslog-ng. Reporting bugs, testing changes, writing code or simply providing feedback are all important contributions, so please if you are a user of syslog-ng, contribute.

syslog-ng 3.3.5 has been released

------------------------------------------------------------------------------ PACKAGE : syslog-ng VERSION : 3.3.5 SUMMARY : new stable release DATE : May 1, 2012 ------------------------------------------------------------------------------ DESCRIPTION: A new stable version of syslog-ng Open Source Edition (3.3.5) has been released. For latest fixes in the 3.3.x feature branch you are recommended to upgrade to this version. CHANGES: 3.3.5 Sat, 07 Apr 2012 10:35:25 +0200 Bugfixes: ========= * Fixed a significant memory leak that occurred when the receiver side of a syslog connection is slower than syslog-ng.

Right now, syslog-ng will drop the affected packet, as the other two could cause other tasks to starve (wait some time) OR syslog-ng to use 100% CPU. Other changes: ============== * The XML sources for manual pages are now included in the source tarball, along with a set of already built man pages to avoid having to install XML related toolings to compile syslog-ng. The path to the stylesheets and the path to xsltproc is hard-coded in the Makefiles right now (to the paths used by Ubuntu 11.10) In case you want to change and rebuild manpages these need to be adjusted. Patches to autodetect the proper paths on any system would be welcome. * Rewrite expressions report an error during the configuration parsing phase instead of silently (ok with a warning :) falling back to changing the MESSAGE macro.
