Closed requested to merge pkoppenb-IDVAlgorithm into master
LoKi functors, as well as some other tools, assume they are owned by a DVAlgorithm and use the tools configured within. Typically, BPVIPCHI2() assumes the existence of the geometry tool. This was reported bu @amathad in https://gitlab.cern.ch/lhcb-dpa/project/-/issues/173 following https://mattermost.web.cern.ch/lhcb/pl/tddzihtuitbdtq1ifajt4pj6zh.
There's no point fixing LoKi as eventually its functors will be replaced by ThOr. BPVIPCHI2 is already. In the meantime make sure there is no crash but exit gracefully instead. With this MR the message is
FunctionalParticleMaker.LoKi::Hy... FATAL Exception with tag=Gaudi::Utils::getIDVAlgorithm is caught FunctionalParticleMaker.LoKi::Hy... ERROR Gaudi::Utils::getIDVAlgorithm Cannot find IAlgorithm. You probably cannot use this tool/functor in this context StatusCode=FAILURE ToolSvc ERROR Error initializing tool 'FunctionalParticleMaker.LoKi::Hybrid::TrackSelector' HiveDataBrokerSvc FATAL in sysInitialize(): exception with tag=FunctionalParticleMaker is caught HiveDataBrokerSvc ERROR FunctionalParticleMaker Failed to retrieve tool LoKi::Hybrid::TrackSelector/LoKi::Hybrid::TrackSelector StatusCode=FAILURE ServiceManager ERROR Unable to initialize service "HiveDataBrokerSvc" HLTControlFlowMgr FATAL Error retrieving HiveDataBrokerSvc ServiceManager ERROR Unable to initialize Service: HLTControlFlowMgr ApplicationMgr ERROR Application Manager Terminated with error code 1
I suggest to backport to run 2.
