Changes for version 2.50_3060 - 2012-07-28

  • -Fixed Helios::Config->init() RT#78616 -Added Helios::Error::ConfigError exception to throw in case of configuration problems.

Changes for version 2.50_3040 - 2012-07-26

  • -changes to Helios::ObjectDriver::DBI and helios.pl to properly handle database connections between parent and child processes (prevents children from attempting to disconnect parent db connections) -helios.pl: changed new worker_blitz_factor param to WORKER_BLITZ_FACTOR for consistency with OVERDRIVE, HOLD, etc. WORKER_BLITZ_FACTOR is now dynamically updated instead of set only at runtime. -Updated lib/Bundle/Helios.pm so it's proper package name is Bundle::Helios, not Bundle::Helios::Generic (oops).

Changes for version 2.50_2910 - 2012-07-16

  • -Helios::Service: changes to dbConnect(), jobsWaiting() to prevent clobbering of Helios::ObjectDriver::DBI connections in some cases. -Helios::Service: replaced try {} otherwise block with eval {} or do in getFuncidFromDb(). -Updated copyright notices in README and Helios.pm to include notifications of Logical Helion and Six Apart code (the notices were intact on the code in question).

Changes for version 2.50_2860 - 2012-07-15

  • -NEW Helios::Config module to handle parsing of configuration information, and modifications to Helios::Service and helios.pl to use it instead of the old getConfigFromIni() and getConfigFromDb() methods.

Changes for version 2.50_2850 - 2012-07-11

  • -Helios::TheSchwartz and Helios::ObjectDriver::DBI added to implement DBI-level database connection caching. Helios::Service, Helios::Logger, and Helios::Job and helios.pl have been changed to use the new connection handling scheme. -Changed Bundle::Helios::Generic to Bundle::Helios (since the RedHat-specific bundle has been eliminated). -helios.pl: added worker_blitz_factor configuration parameter to allow MAX_WORKERS workers to launch before there are that many jobs available in the job queue.
