The London Perl and Raku Workshop takes place on 26th Oct 2024. If your company depends on Perl, please consider sponsoring and/or attending.

Changes for version 2.72_0950 - 2014-02-28

  • HELIOS 2.80 RELEASE CANDIDATE 1 -Resolved service/service_name inconsistency in Helios::Config API. Accessor method is set/getService, and the get/set/unsetParam methods take 'service' as a parameter. The set/getServiceName() methods are retained for backward compatibility. -Changed WORKER_LAUNCH_PATTERN names to be more descriptive: linear, dynmaic, optimistic. As before, linear is the default. -Filled gaps in Helios::Configuration guide and helios.pl POD. -Updated copyright info.

Changes for version 2.71_4770 - 2013-11-24

  • Removed .pl extension from all new commands.
  • Helios::Config->setParam(): fix so false values can be set.
  • helios.pl: tweaks to database reconnect code.
  • helios.pl: changes to command line option parsing so multiple jobtypes can be specified with multiple --jobtypes options.
  • helios.pl: removed all use Error-based try {} catch {} blocks. This will allow future Helios versions to use exceptions based on Exception::Class rather than Error.
  • Helios::TheSchwartz has been removed; Helios::TS has completely replaced it.

Changes for version 2.71_4460 - 2013-11-02

  • Minor changes and fixes to new commands:
  • helios_config_get.pl: fixed problem with not returning param values set in helios.ini.
  • helios_config_set.pl: fixed problem with setting param values that evaluate to false.
  • helios_config_unset.pl: changed output to make it more consistent with the other new commands.
  • helios_job_status.pl, helios_job_info.pl: specifying --jobid no longer required; the first arg is assumed to be the jobid.
  • helios_job_submit.pl: -v and -n now work in addition to --verbose and --no-validate.
  • helios_service_status.pl: separated service version to its own line in output. Added '--epoch-time' option to report time in epoch seconds instead of localtime() format.

Changes for version 2.71_4350 - 2013-10-25

  • NEW helios_service_status.pl - report service status.
  • NEW helios_job_status.pl - report job exitstatus (if completed).
  • NEW helios_job_info.pl - report job metainfo, args, and log msgs.
  • helios_config_*.pl: added documentation.
  • Helios::Config - fixed warning using getParam().

Changes for version 2.71_4250 - 2013-10-18

  • Helios::Config:
    • NEW set/get/unsetParam() methods to more easily work with individual config parameters in the HELIOS_PARAMS_TB table.
    • NEW helios_config_*.pl commands to make Helios config params more accessible to shell scripts and other utilities.
    • parseConfDb(): combined the 2 separate database queries into 1 to reduce database calls when config is updated.
    • separated Helios config parameter documentation into Helios::Configuration POD.
  • Helios::Service:
    • Added JobLockInterval() functionality to control the amount of time jobs are locked from a Helios API. Previously, the only way to control the amount of time jobs were locked was to override TheSchwartz::Worker's grab_for() method.
    • Changed hostname lookup handling to reduce the number of calls to Sys::Hostname::hostname().
  • helios.pl:
    • Changed cmd line option handling so --help and --version work again.
    • Added startup message to report the dsn of the collective database helios.pl is connected to.
    • Replaced most Error module-based try {} blocks with eval {}
    • Updated POD with new cmd options and referenced Helios::Configuration.
  • Helios::Job - replaced usage of Helios::TheSchwartz with the new Helios::TS class.
  • Helios::JobType - added debug() accessor method.
  • Makefile.PL: Added all helios_config_*.pl commands above and helios_jobtype_add.pl to EXE_FILES. Removed old LICENSE line.

Changes for version 2.71_4051 - 2013-10-04

  • Added code for "virtual jobtypes" - jobtypes w/o a service class. Allows a service to handle jobs of multiple jobtypes without creating new service classes.
  • NEW Helios::ObjectDriver class to improve driver init handling.
  • NEW Helios::JobType class to represent jobtypes; there should no longer be a need to use TheSchwartz::FuncMap directly.
  • NEW Helios::TS and Helios::TS::Job to:
    • replace Helios::TheSchwartz as a full-featured TheSchwartz subclass.
    • implement virtual jobtypes.
    • fix [RT79690] by dumping Helios::TS::Job objects w/o arg() values before they are passed to the higher Helios layers.
  • NEW helios_jobtype_add.pl to handle adding new jobtypes from the command line.
  • helios.pl:
    • now handles @ARGV completely differently to support virtual jobtype specification and add other options in future.
    • uses Helios::TS instead of Helios::TheSchwartz
  • Helios::Service:
    • new, better constructor
    • ton of NEW methods to support virtual jobtypes: set/getJobType() addAltJobType() set/getAltJobTypes() set/getAltJobtypeids() addAltJobtypeid() lookupAltJobtypeids() lookupJobtypeid()
    • jobsWaiting(): rewritten to support multiple, "virtual" jobtypes

Changes for version 2.71_3860 - 2013-09-21

  • Added PRIORITIZE_JOBS feature.
  • Added WORKER_LAUNCH_PATTERN feature.
