Changes for version 2.50_3161 - 2012-08-04

  • -Helios::Service->dbConnect(): new version to properly handle "options" config param for databases, properly separate Helios collective database connections from connections to other databases. Updated documentation. -Helios::Service: Updated copyright info in several places. -helios_job_submit.pl & helios_log_clean.pl: updated to use new configuration subsystem.

Changes for version 2.50_3160 - 2012-08-04

  • Significant changes to configuration subsystem. -Helios::Config->init() now clears all already parsed config data structures. The init() method should normally only be called once. -Helios::Service: significant changes to how Helios::Service interacts with Helios::Config. -Added ConfigClass() method to specify alternate config modules (like JobClass() and Helios::Job). -Added initConfig() method to call init() for whatever config module is specified and $INIT_CONFIG_CLASS to keep track of what config module has been initialized. -The prep() method will now only call initConfig() to initialize the config module once, but will always call parseConfig() to update current config parameters (unless a cached config was given when LAZY_CONFIG_UPDATE is active). -getConfigFromIni() and getConfigFromDb() have been rewritten to use Helios::Config (or whatever ConfigClass() is set). However, use of these methods is now deprecated, as Helios::Config and its subclasses can be used directly. -t/1.t and t/2.t have been updated to test Helios::Config functionality.

Changes for version 2.50_3070 - 2012-07-29

  • -helios.pl: Added DOUBLE_CLUTCH_INTERVAL config param to support WORKER_MAX_TTL functionaity. Updated copyright info.

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.
