Can you help identify ambiguous CPAN distributions?

Hello, Perl community. As I work on converting legacy CPAN Testers (CT1.0) reports to the new CPAN Testers 2.0 (CT2.0) format, I’ve encountered a curious conundrum and could use some volunteer help.

CT1.0 indexes reports based on the distribution name and version, e.g. “Foo-Bar-1.23”. This is an unfortunate historical accident, since PAUSE does not prevent uploads with the same file name to different author directories:

  • JDOE/Foo-Bar-1.23.tar.gz
  • JQPUBLIC/Foo-Bar-1.23.tar.gz

CT2.0 will index reports based on the full unique distribution file path. I’m currently working on a heuristic to link any given legacy test report (on “Foo-Bar-1.23”) with the correct distribution file path for that distribution name and version for the conversion to CT2.0.

For the most part, it works. Usually, there is only one distribution file path on BackPAN that matches. Sometimes there is more than one possibility, but I’ve worked out ways to resolve the ambiguity by comparing the possibilities to information in the 01mailrc files or the 02packages.details file.

But there are about 50 distribution name-version pairs on BackPAN that my heuristic fails to resolve. Since this is a one-time conversion from CT1.0 to CT2.0, all I need is a mapping file with entries like this for these ambiguous cases:

YAML-0.39    INGY/YAML-0.39.tar.gz

If you think you can help – either through some automated approach or just by volunteering your human brain to do some basic research to identify the “authoritative” path (e.g. historical author list in the distribution documentation files), that would be a great help for me so I can keep plugging away on the conversion code and other todos.

Even confirming that the candidates on BackPAN have the same md5 sum would be helpful since then even if we guess the wrong author, the test results are still “good” for the mistaken distribution file.

Here is the list. The name-version pair is followed by an indented list of possible paths for that pair.
