Description

If you open a TRootBrowser, double click on a TFile, right click on TTree, select Scan from the Menu, and write some values in varexp and selection, and click OK, the input is ignored.

It fails at least since ROOT 6.18
It works well in ROOT 5.34
I did some debugging and it seems the problem is in metacling, the "params" argument is lost deep inside the TClingCallFunc routines.

It is correct here:

10 TCling::Execute TCling.cxx 5281 0x7efc7f542288
params = ""time","","",(Long64_t)kMaxEntries,(Long64_t)0"

with gDebug=6:

thanks for the report @ferdymercury . I added in the loop @bellenot who might have an idea on how to move forward.

[bellenot]

@dpiparo Well, since it's in the interpreter generated code, and not in the GUI per se, I don't know how to fix it, but I can try to have a look if you want. And note that this is most probably also the case for every methods annotated with // *MENU* (and maibe also // *SIGNAL*? ) and containing a constant like kMaxEntries. And this is more for @pcanal or any meta/interpreter expert, if you know any 😉

Oneliner reproducer in batch mode:

Fails:

root -l -e 'TTree* t = new TTree("t","tree"); bool event_pileup_flag; ULong64_t event_time; t->Branch("time", &event_time, "time/l"); t->Branch("pileup", &event_pileup_flag, "pileup/O"); event_time=1; event_pileup_flag=false; t->Fill(); event_time=2; event_pileup_flag=true; t->Fill(); gInterpreter->Execute(t, t->IsA(), "Scan", "\"time\",\"pileup==1\",\"\",(Long64_t)kMaxEntries,(Long64_t)0");' -b -q

Works:

root -l -e 'TTree* t = new TTree("t","tree"); bool event_pileup_flag; ULong64_t event_time; t->Branch("time", &event_time, "time/l"); t->Branch("pileup", &event_pileup_flag, "pileup/O"); event_time=1; event_pileup_flag=false; t->Fill(); event_time=2; event_pileup_flag=true; t->Fill(); gInterpreter->Execute(t, t->IsA(), "Scan", "\"time\",\"pileup==1\",\"\",(Long64_t)100,(Long64_t)0");' -b -q

Problem seems to be in LookupHelper::findFunctionArgs
