MINOR: Save space in logs

Hi people! I just wanted to suggest to comment out two printouts in SVFit and HHKinFit as they are quite unuseful but very very frequent. TauAnalysis/ClassicSVfit/src/MeasuredTauLepton.cc L57-58 and HHKinFit2/HHKinFit2Scenarios/src/HHKinFitMasterHeavyHiggs.cpp L261-262-252

---

EDIT (Francesco)

To be fixed (see this comment below):

• SVFit/FastMTT warning --> see https://gitlab.cern.ch/cclubbtautau/AnalysisCore/-/merge_requests/50
• HHKinFit warnings

added enhancement label

For HHKinFit we clone the original repo, so we cannot silence the warnings (unless we fork the repo and clone from there).

For SVFit instead it can be done since we already clone a fork of the repository.

But are the logs really so much bigger? Could you give an estimate of size/how many lines of this warning are there?

There thousands of these warnings printed in every file!

Ok I took the log for one job of DYto2L-2Jets_MLL-50 from run3_2023_postBPix, which should correspond to file:

/store/mc/Run3Summer23BPixNanoAODv12/DYto2L-2Jets_MLL-50_TuneCP5_13p6TeV_amcatnloFXFX-pythia8/NANOAODSIM/130X_mcRun3_2023_realistic_postBPix_v2-v3/80000/11f26cf5-3eba-4d99-85d5-567f055c0ff4.root

which has 596432 events.
The log file size is:

File	size (bytes)	Gain wrt original
Original	68551	-
SVFit log removed	59172	13.7%
KinFit log removed	46344	32.4%
Both log removed	36965	46.1%

So overall maybe we should consider forking our own KinFit repo and commenting out those printouts. I could take a look at this after I'm done with DY stitching.

In any case, just for reference here are the exact lines to be commented out:

• SVFit: https://github.com/LLRCMS/ClassicSVfit/blob/bbtautau_CCLUB/src/MeasuredTauLepton.cc#L60-L61
• KinFit 1: https://github.com/bvormwald/HHKinFit2/blob/CMSSWversion/HHKinFit2Core/src/HHFitObjectE.cpp#L82-L86
• KinFit 2: https://github.com/bvormwald/HHKinFit2/blob/CMSSWversion/HHKinFit2Scenarios/src/HHKinFitMasterHeavyHiggs.cpp#L261-L263
