PR description:

This PR fixes the following error:

----- Begin Fatal Exception 07-Jan-2025 11:36:39 CET-----------------------
An exception of category 'WrongPluginLoaded' occurred while
   [0] Constructing the EventProcessor
Exception Message:
The plugin 'Phase2HLTMuonSelectorForL3' should have been loaded from
 '/cvmfs/cms-ib.cern.ch/sw/x86_64/nweek-02870/el8_amd64_gcc12/cms/cmssw/CMSSW_15_0_X_2024-12-29-0000/lib/el8_amd64_gcc12/pluginRecoMuonL3MuonProducer.so'
 but instead it was already loaded from
 '/cvmfs/cms-ib.cern.ch/sw/x86_64/nweek-02870/el8_amd64_gcc12/cms/cmssw/CMSSW_15_0_X_2024-12-29-0000/lib/el8_amd64_gcc12/pluginRecoMuonL3TrackFinderPlugins.so'
 because some other plugin was loaded from the latter loadables.
To work around the problem the plugin 'Phase2HLTMuonSelectorForL3' should only be defined in one of these loadables.
----- End Fatal Exception -------------------------------------------------

I first noticed this when developing on top of one of the latest IBs and then followed it in the past few IBs. The IB logs mostly detect it in the arm backend, but I've found the reported error when trying to run the 29850.778 workflow. Curiously, this issue is only present in the IBs: I have not been able to reproduce it starting from CMSSW_15_0_0_pre1 and just merging #46897.

PR validation:

I've tested the fix once again on 29834 and 29850 workflows with no modifiers as well as .777 and .778 in both cases. No such error is reported anymore.

Comparison Summary

There are some workflows for which there are errors in the baseline:
29834.778 step 2
29850.778 step 2
The results for the comparisons for these workflows could be incomplete
This means most likely that the IB is having errors in the relvals.The error does NOT come from this pull request

Summary:

  • You potentially added 71 lines to the logs
  • Reco comparison results: 1 differences found in the comparisons
  • DQMHistoTests: Total files compared: 53

the whole package RecoMuon/L3TrackFinder could be reorganized such that all the plugins are actually in the plugins folder (and the SealModules.cc file is thus removed),

commit mmusich@aae2698 offers an implementation (I tested it passes both runTheMatrix.py --what upgrade -l 29850.778 --ibeos and addOnTests).

I would look into removing a bunch of SealModules at least from the Muon part of CMSSW in a separate PR

This pull request is fully signed and it will be integrated in one of the next master IBs (tests are also fine). This pull request will now be reviewed by the release team before it's merged. @antoniovilela, @rappoccio, @mandrenguyen, @sextonkennedy (and backports should be raised in the release meeting by the corresponding L2)
