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.
