Hi Philippe,
following my questions from yesterday I spend another afternoon hunting
bugs in root (at least I consider this to be a bug).
What I do is (same file/library as yesterday):
1. Create a chain inputChain
2. Add a file to it
3. Then
inputChain->SetBranchStatus("*",0);
inputChain->SetBranchStatus("BRawHeader",1); <- This is a split branch
b_header=inputChain->GetBranch("BRawHeader");
TRawHeader *header=0;
b_header->SetAddress(&header);
inputChain->GetEntry(3)
-> No byte is read, but lots of constructors called, we had that
yesterday...
header->Print()
-> header is not filled, but at least no crash...
You can now nicely enable the individual branches of the split branch but
enabling them all via inputChain->SetBranchStatus("BRawHeader",1); does
not seem to work. This is especially problematic as I don't know in my
code which input branches I have to expect. I consider this behaviour a
bug, since enabling a branch should work irrespective of its split status.
Cheers,
Birger
