Bug #22643
Custom setPtr instantiations not honored
Description
With the change from art 2 to art 3, the template instantiations provided by mu2e's OwningPointerCollection are no longer picked up by the compiler, resulting in incorrect results. Analysis should be done whether this is a bug in art, or whether there are simple changes in mu2e code that can fix this error.
History
#1 Updated by Kyle Knoepfel 9 months ago
The problem is understood. A line of code deep within art (canvas, actually), changed from calling setPtr(...) to art::setPtr(...). The explicit 'art::' qualification thus discarded the customized mu2e::setPtr template specialization that Mu2e has provided for the mu2e::OwningPointerCollection. The customized behavior is restored by removing the explicit 'art::' qualification.
This fix requires a new art release. We have other bug fixes ready to go in, so we would like to release an art 3.02 bug-fix release. Does that sound reasonable?
