Do we use PROOF?

[iarspider]

In root-project/root#14513, PROOF was made optional (off by default), causing test failures when testing new ROOT master version: link.

However, it is only used by two tests:
FWCore/TFWLiteSelector/test/proof_thing_sel.C and FWCore/TFWLiteSelector/test/proof_thing2_sel.C.

Should we explicitly enable PROOF, or should we drop these two tests?

I'm OK with dropping PROOF support. I don't know of anyone who ever used our extra code built on top of PROOF.

[dan131riley]

I agree with dropping it, I think PROOF has been passed by in favor of other developments.

[makortel]

I'm fine with dropping it, but maybe we should announce it somewhere? (just to make sure)

[smuzaffar]

agree. Is announcing it on SW development forum enough?

We could hope so :) (i.e. I don't have a better forum to suggest)

PROOF tests were removed in #43996

[makortel]

The removal was announced in https://cms-talk.web.cern.ch/t/removal-of-roots-proof-in-the-future/34915

[makortel]

Do we already have a cmsdist PR that drops the PROOF from ROOT?

[iarspider]

@makortel kind of: cms-sw/cmsdist#8999 . Or should I make PR(s) to explicitly disable PROOF in branches where it is enabled by default?

[makortel]

No, I think the cmsdist PR of ROOT update (where they changed the default) does the job (and follows what your announcement message). I just wanted to record the cmsdist PR here.
