OpenSRF 3.1

We are pleased to announce the release of bugfix releases (3.0.3 and 3.1.1) of OpenSRF, a message routing network that offers scalability and failover support for individual services and entire servers with minimal development and deployment overhead.

OpenSRF 3.0.3 and 3.1.1 include a performance improvement; all users of OpenSRF 3.0.x and 3.1.x are encouraged to upgrade as soon as possible.

The following bugs are fixed in OpenSRF 3.0.3 and 3.1.1:

• LP#1824181 and LP#1824184: Improve the performance of certain logging statements. OpenSRF application code written in Perl can now pass a subroutine reference to a logging statement instead of a string. This allows complicated expressions to generate text for a log message to not be run unless actually needed at the current logging level. For example, a logging statement of$logger->debug('message')

  can now be alternatively be represented as

  $logger->debug(sub { return 'message' })

  OpenSRF now uses this mechanism for a debug logging statement in method_lookup(). This has the effect of reducing the time to run some methods in Evergreen’s open-ils.storage by 90%.

OpenSRF 3.1.1 also marks the end of formal installation support for Ubuntu 14.04 Trusty Tahr, which is no longer supported by Ubuntu.
