DIRAC v7r0

DIRACOS

As of v7r0, Externals and Lcgbundle packages are replaced by DIRACOS. Note that runit, as well as mySQL, are not anymore distributed, and you must install them by yourself. RPMs are provided here: http://diracproject.web.cern.ch/diracproject/rpm/

Core

it is now possible to use M2Crypto instead of PyGSI by setting the environment variable DIRAC_USE_M2CRYPTO=Yes in the bashrc. This is a technology preview as described here https://dirac.readthedocs.io/en/integration/AdministratorGuide/technologyPreviews.html

AccountingSystem

PR https://github.com/DIRACGrid/DIRAC/pull/3701 merges the ObjectLoaders and TypeLoaders used in AccountingSystem and MonitoringSystem into a single one. Pay attention in case you use them.

alter table `ac_key_LHCb-Production_Job_FinalMinorStatus` MODIFY value VARCHAR(256) NOT NULL;

alter table `ac_in_LHCb-Production_Job` MODIFY FinalMinorStatus VARCHAR(256) NOT NULL;

Jobs parameters on ElasticSearch backend

• It's possible (and advised) to store the Jobs parameters on ElasticSearch (up to now, they have been stored in a key/value pair MySQL table, part of JobDB).

TransformationSystem

PR https://github.com/DIRACGrid/DIRAC/pull/3703 replaces the TransformationInputDataQuery table with a new table TransformationMetaQuery, which stores both Input and Output MetaQueries. In order to guarantee backward compatibility, before deploying the release, it's necessary to rename the TransformationInputDataQuery table and create a view as following:

  ALTER TABLE `TransformationInputDataQuery` RENAME `TransformationMetaQuery`, 
  ADD COLUMN QueryType VARCHAR(8), 
  CHANGE COLUMN `ParameterName` `MetaDataName` VARCHAR(512) NOT NULL, 
  CHANGE COLUMN `ParameterValue` `MetaDataValue` blob NOT NULL,  
  CHANGE COLUMN `ParameterType` `MetaDataType` VARCHAR(8) NOT NULL;
  CREATE OR REPLACE VIEW `TransformationInputDataQuery` AS 
  SELECT TransformationID, 
  MetaDataName as ParameterName, 
  MetaDataValue as ParameterValue,  
  MetaDataType as ParamaterType
  from TransformationMetaDataQuery;

ProductionSystem

With v7r0, with PR https://github.com/DIRACGrid/DIRAC/pull/3703, a completely new system is put in place: the ProductionSystem, which is used for high-level productions management.
