Unexpected parsing of classes by ROOT 6.24 #40375

Open Dr15Jones opened 1 year ago

Dr15Jones commented 1 year ago

When turning on gDebug = 2 and INFO messages, I see the following

In both cases, we have explicit directives to generate the dictionaries https://github.com/cms-sw/cmssw/blob/6d2f66057131baacc2fcbdd203588c41c885b42c/TrackingTools/PatternTools/src/classes_def.xml#L2

I see this for other cases as well, such as reco::Muon.

One particular one that stands out is the message

where this does have an explicit dictionary

pcanal commented 1 year ago

Does std::vector<reco::Track> also have a dictionary? (does any FindUsingAdvance have a dictionary?)

Dr15Jones commented 1 year ago

Does std::vector also have a dictionary?

Yes https://github.com/cms-sw/cmssw/blob/6d2f66057131baacc2fcbdd203588c41c885b42c/DataFormats/TrackReco/src/classes_def.xml#L351

(does any FindUsingAdvance have a dictionary?)

No, as the type has no state and is not a member of Ref (it just says how to go to the next element in the container).

pcanal commented 1 year ago

For debugging purpose, can you request a dictionary for edm::refhelper::FindUsingAdvance<std::vector<reco::Track> and see it changes the behavior?

Dr15Jones commented 1 year ago

@pcanal adding the FindUsingAdvance dictionary made a small (I don't think overly important) difference.

Doing diff on the two logs (with the old being '<' and the new with the dictionary being '>')

Dr15Jones commented 1 year ago

I guess one difference is ROOT did not do Starting autoparse for vector<reco::Track> once there was an explicit FindUsingAdvance dictionary.

pcanal commented 1 year ago

Note that we were working on a similar issue (https://github.com/cms-sw/cmssw/issues/33196) last year but did not come to a conclusion.

The diff output seems to show 2 things. One is that adding the dictionary for the FindUsingAdvance class does seem to prevent the auto parsing. Second, for some reason to trying many times to auto parse the same classes (hypothesis: it might be because it fails when trying for FindUsingAdvance)

Dr15Jones commented 1 year ago

One can find the log files at FNAL /uscms_data/d2/cdj/build/temp/fix/root6/CMSSW_13_0_ROOT6_X_2022-12-15-2300/matrix/4.44_RunElectron2012A/rootdebug*.log

pcanal commented 1 year ago

It is puzzling why it is still doing the autoparse for reco::Track :(

makortel commented 1 year ago

I dug a bit of the history of the explicit FindUsingAdvance dictionary mentioned in https://github.com/cms-sw/cmssw/issues/33196#issuecomment-800505283. It was merged in master in https://github.com/cms-sw/cmssw/pull/8362, and in the ROOT6 branch of the time in https://github.com/cms-sw/cmssw/pull/5858. The latter PR suggests that the need for explicit FindUsingAdvance dictionary to avoid auto-parsing might have been observed already then?

Dr15Jones commented 1 year ago

From the debugging output from ROOT, here are all the classes for which it says it will be running the parser. The vast majority look like they are from member data we marked as transient.

@pcanal

What if in this loop https://github.com/root-project/root/blob/0336235b97dc8eda16536a182006e41e0a44e823/core/meta/src/TProtoClass.cxx#L241-L250

any element marked 'transient' would be skipped rather than having to try to load its TClass?

pcanal commented 1 year ago

In that loop we already suspend the autoparsing, so I would suspect it would make no difference. Do you see the autoparsing coming from that path?

Dr15Jones commented 1 year ago

I see the message prefixed by Treating beforehand mother class for the various classes which are associated with transient data members.

I believe I have found a race condition between calling TFile::Open and TClass::GetClass

If I modify the program to just call TFile::Open things are fine and if it just calls the TClass::GetClass functions. Only when they are done together does the problem appear.

pcanal commented 1 year ago

I see the message prefixed by Treating beforehand mother class for the various classes which are associated with transient data members.

That does indicates the loop is working as expected, but it should not imply auto-parsing triggered for those classes through that code path.

pcanal commented 1 year ago

I believe I have found a race condition between calling TFile::Open and TClass::GetClass

That looks indeed bad. Let me try to reproduce it.

Dr15Jones commented 1 year ago

On another run in gdb I get a segmentation fault in the TFile::Open path while the TClass:GetClass path is running

So adding 

   ROOT::EnableImplicitMT(
                          oneapi::tbb::global_control::active_value(oneapi::tbb::global_control::max_allowed_parallelism));

to the program seems to have resolved the crashes.

So adding ... [something related to ROOT threading] ... resolved the crashes.

Right. I missed it but the minimal example above is missing:

ROOT::EnableThreadSafety();
