Changelog for 5.5.6 (devel)

adisconteamChangelog, ,

Version 5.5.6  [DEVEL] (rgerhards), 2010-07-21

  • added parser modules
    • pmlastmsg, which supports the notoriously malformed “last message repeated n times” messages from some syslogd’s (namely sysklogd)
    • pmrfc3164sd (contributed), supports RFC5424 structured data in RFC3164 messages [untested]
  • added new module type “string generator”, used to speed up output processing. Expected speedup for (typical) rsyslog processing is roughly 5 to 6 percent compared to using string-based templates.
    They may also be used to do more complex formatting with custom C code, what provided greater flexibility and probably far higher speed, for example if using multiple regular expressions within a template.
  • added 4 string generators for
    • RSYSLOG_FileFormat
    • RSYSLOG_TraditionalFileFormat
    • RSYSLOG_ForwardFormat
    • RSYSLOG_TraditionalForwardFormat
  • bugfix: mutexes used to simulate atomic instructions were not destructed
  • bugfix: regression caused more locking action in msg.c than necessary
  • bugfix: “$ActionExecOnlyWhenPreviousIsSuspended on” was broken
  • bugfix: segfault on HUP when “HUPIsRestart” was set to “on” thanks varmojfekoj for the patch
  • bugfix: default for $OMFileFlushOnTXEnd was wrong (“off”).

This, in default mode, caused buffered writing to be used, what means that it looked like no output were written or partial lines. Thanks to Michael Biebl for pointing out this bug.

Changelog for 5.5.5 (devel)

Version 5.5.5 [DEVEL] (rgerhards), 2010-05-20

  • added new cancel-reduced action thread termination method
    We now manage to cancel threads that block inside a retry loop to terminate without the need to cancel the thread. Avoiding cancellation helps keep the system complexity minimal and thus provides for better stability.
    This also solves some issues with improper shutdown when inside an action retry loop.

rsyslog 5.5.5 (devel) released

adisconteamNews, Release Announcement, ,

Hi all,

We have just released rsyslog 5.5.5, a member of the devel branch. This is a bug-fixing release which contains a single fix that solves a potential hang condition on system shutdown when infinite action retries are configured for an asynchronous action using a queue in disk-assisted mode and the action was suspended. This is probably not a very common case, but a configuration recommended by our doc samples. If you do not use such a configuration, there is no need to update at this time. See Changelog for more details.
