@perrotta @qliphy
Could you please confirm no change policy for production release in this case? Thanks.

[qliphy]

@srimanob Run3 production has been launched with 12_0_X, and this PR indeed bring changes.
Adding @rappoccio who may comment more.
Or we can discuss this at next ORP.

[civanch]

We discussed at the recent SIM meeting if we should backport to 12_0 and agree that we prepare backports of all PRs related to geometry. This does not mean that all will be merged. We do this in order to be ready if a decision would be made to have 12_0 geometry equal to 12_1.

[srimanob]

Thanks @civanch
I misunderstood that we need to merge it when PR is ready. So maybe I will hold it until we have a discussion at ORP.

[srimanob]

hold

[cmsbuild]

Pull request has been put on hold by @srimanob
They need to issue an unhold command to remove the hold state or L1 can unhold it for all

[srimanob]

unhold

[srimanob]

Following the release meeting, this PR can merge.

The 12_0 production uses 12_0_1 but with DB geometry equivalent to XML we have in 12_0_0. In principle, production can be controlled by GT if new CMSSW will be needed in future.

Note that, in the 12_0_X, autocond currently points to the new GT (with updated geometry) already
https://github.com/cms-sw/cmssw/blob/CMSSW_12_0_X/Configuration/AlCa/python/autoCond.py#L71
120X_mcRun3_2021_realistic_v7 is advance one compared to 120X_mcRun3_2021_realistic_v5 (GS) and 120X_mcRun3_2021_realistic_v6 (DR) used in production. v7 include updated in geometry introduced in 12_0_1.

+Upgrade

[cmsbuild]

This pull request is fully signed and it will be integrated in one of the next CMSSW_12_0_X IBs (tests are also fine) and once validation in the development release cycle CMSSW_12_1_X is complete. This pull request will now be reviewed by the release team before it's merged. @perrotta, @dpiparo, @qliphy (and backports should be raised in the release meeting by the corresponding L2)

[cvuosalo]

urgent

[perrotta]

backport of #35290 and (part of) #34983 and #35210

[perrotta]

Just trying to understand how this backport was designed: this line is from #34983, and it was apparently forgotten in some previous backport of that PR merged in master: could you please explain the logic and the history of previous backports?

[bsunanda]

We had a few PR for 12_1_X and these are combined in the backport PR. Please merge this PR. It is in the way of other back-outings

[bsunanda]

@perrotta @qliphy Please merge

[qliphy]

@perrotta @qliphy Please merge

I am fine with this PR. I will let @perrotta have a check again and merge later if possible.

[perrotta]

@bsunanda, I'm trying to follow the complicate line of backports from several sources...
Why there is not the backport of the "v2" of tecmaterial.xml? Is it the same as "v1", and therefore it is notbackported for simplicity?

[bsunanda]

@perrotta We found later there is no need to have "v2" for tecmaterial. So a later PR (#35290) deletes "v2" for tecmaterial and current version in 12_1_X makes use of v1 version of tecmaterial.
