This pull request is fully signed and it will be integrated in one of the next CMSSW_12_4_X IBs (tests are also fine) and once validation in the development release cycle CMSSW_14_1_X is complete. This pull request will now be reviewed by the release team before it's merged. @sextonkennedy, @antoniovilela, @rappoccio (and backports should be raised in the release meeting by the corresponding L2)
hold
- This looks like a major change so will need to be discussed at the ORP meeting and signed off by PPD.
Pull request has been put on hold by @rappoccio
They need to issue an unhold
command to remove the hold
state or L1 can unhold
it for all
Hi @rappoccio , thanks for reviewing.
I would like to point out here that the large amount of changes shown by github are in large part refactorings - I have replaced the PowhegHooksBB4L.h
file that was in CMSSW by a clean - but functionally similar - version provided directly by the BB4L authors. Also, I think it is important to note that this change will only affect MC generation using the BB4L hooks, i.e. only the BB4L samples that we plan to submit once this is merged.
Since GEN L2s have signed off and no other parts of CMSSW are affected, I wanted to ask whether it is really necessary to go to PPD for approval here.
Cheers,
Laurids
