Description
The following code works 100% fine on 6.10.06 – but I tried the above ROOT versions and they all crash with the same error
import ROOT
|
|
|
for fname_in, fname_out in [
|
["copied/Sig_Gbb.offshell_mc16a_21.2.87-1_output_histfitter.root.2", "cloned/Sig_Gbb.offshell_mc16a_21.2.87-1_output_histfitter.root.1"],
|
["copied/Sig_Gbb.offshell_mc16e_21.2.87-1_output_histfitter.root.3", "cloned/Sig_Gbb.offshell_mc16e_21.2.87-1_output_histfitter.root.1"],

|
]:
|
print("Opening ", fname_in)
|
f_in = ROOT.TFile.Open(fname_in)
|
treenames = set(k.GetName() for k in f_in.GetListOfKeys())
|
|
|
print("Opening ", fname_out)
|
f_out = ROOT.TFile.Open(fname_out, "RECREATE")
|
|
|
for treename in treenames:
|
print("\t{}".format(treename))
|
tree_in = f_in.Get(treename)
|
print("\t\tCloning")
|
tree_out = tree_in.CloneTree(-1, "fast")
|
print("\t\tWriting")
|
f_out.Write("", ROOT.TObject.kOverwrite)
|
print("\tFinished")
|
|
|
print("Closing ", fname_out)
|
f_out.Close()
|
print("Closing ", fname_in)
|
f_in.Close()

This code will take a file that has a bunch of trees of various cycles, and just clone only the latest cycle into a new file (to try and clean up/reduce file sizes). Use any ROOT file that has a bunch of trees only. This crashes when trying to copy over the second tree with this sort of error

As you can see, the first tree was fine, but the second crashes. Note that this has no issues in 6.10.06.
