I think this is the tail end task for the 5.41.5 release this past weekend. I hadn't twigged that @bingos had updated Module::CoreList on CPAN. I'll look at this now.

[richardleach]

I've pushed 2cc57ab to blead, which should finish off the 5.41.5 release.

I'm not sure that this fixes this BBC though. Possibly I derped the ordering of changes prior to the CPAN release?

Blead (v5.41.5-17-g161ff7336a) is passing, but if I install it locally, then say ./bin/cpan and, inside the cpan shell, say test Module::CoreList, I am asked whether I want to downgrade that module.

The current configuration of allow_installing_outdated_dists is 'ask/no', but for this option we would need 'CPAN::DistnameInfo' installed. Please install 'CPAN::DistnameInfo' as soon as possible. As long as we are not equipped with 'CPAN::DistnameInfo' this option does not take effect
allow_installing_module_downgrades: BINGOS/Module-CoreList-5.20241020.tar.gz (called for Module::CoreList) contains downgrading module(s) (e.g. 'Module/CoreList.pm' would downgrade installed '5.20241120' to '5.20241020'). Do you want to allow installing it? [no]

cpan[2]> bye

So I think Module::CoreList needs a new CPAN release.

[bingos]

There is no way that the Module::CoreList released to CPAN following blead-point release can ever pass its tests when run against a Perl with a version that it does not know about

In this instance, Module-CoreList-5.20241020 has data on every Perl up to Perl v5.41.5

If you then test that against Perl v5.41.6 it doesn't know about that version and can't possibly know about that without using a time machine.

This is how we have always released Module::CoreList. It gets copied from a checkout of the tag of the blead-point release and I do the release to CPAN.

It isn't anything new either, go back through CPAN Testers results for previous months release of Module::CoreList and you see the same, fails from testing on a Perl version that M::CL has no knowledge of.

http://fast-matrix.cpantesters.org/?dist=Module-CoreList%205.20240920
http://fast-matrix.cpantesters.org/?dist=Module-CoreList%205.20240720
http://fast-matrix.cpantesters.org/?dist=Module-CoreList%205.20240702
etc etc etc.

There is no need for a new CPAN release.

I will put some sanity checks into is_core.t to skip those two tests if it doesn't have data for the version of Perl is being run as.

Phew. Thanks @bingos!
