Backport-CMSSW_15_0_X-fix-Repack-RawSkim-Logic

[LinaresToine]

PR description:

After validating the output of the new feature developed in #47525, we identified a bug in the logic in which the raw skim outputs are overwritten in the PSet file. I will provide details now:

• When a stream is mapped to multiple PDs, it has different HLT paths in each output, one for each PD.
• To make sure that we were selecting events based on the HLT path concerning one of the possible PDs, we create the process attribute in : https://github.com/cms-sw/cmssw/blob/master/Configuration/DataProcessing/python/Repack.py#L84
• The issue is that this is in a loop for each output, so such process.baseSelection object gets overwritten.
• The consequence is that when we enable ReserveDMu raw skim for ParkingDoubleMuonLowMass0 and ParkingDoubleMuonLowMass1, we get identical outputs for each raw skim dataset.

The previous behavior can be seen in the PSet section:

process.baseSelection = cms.EDFilter("HLTHighLevel",
    HLTPaths = cms.vstring('Dataset_ParkingDoubleMuonLowMass1'),
    TriggerResultsTag = cms.InputTag("TriggerResults","","HLT"),
    andOr = cms.bool(True),
    eventSetupPathsKey = cms.string(''),
    eventSetupPathsLabel = cms.string(''),
    mightGet = cms.optional.untracked.vstring,
    throw = cms.bool(True)
)

I have placed the bugged PSet and corresponding output in:

/eos/home-c/cmst0/public/RawSkim/bugged

PR validation:

We tested the changes in this PR locally, and now we get relevant outputs. In summary, we see the following:

• Input file: /eos/cms/store/t0streamer/Data/ParkingDoubleMuonLowMass0/000/391/950/run391950_ls0003_streamParkingDoubleMuonLowMass0_StorageManager.dat --> 321 events
• ParkingDoubleMuonLowMass0_ReserveDMu_RAW --> 56 events
• ParkingDoubleMuonLowMass1_ReserveDMu_RAW --> 32 events

I have placed the new PSet and corresponding output in:

/eos/home-c/cmst0/public/RawSkim/fixed
