Subject: Namespace disorder confusing and risky
Some namespaces seem to have crossed the border between distros in the past. I just became aware of only one example: Mail::Reporter lives in both MARKOV/Mail-Box-2.120.tar.gz and MARKOV/Mail-Message-3.008.tar.gz. Both are indexed for various reasons. If a user first installs Mail::Message and later installs, say, Mail::Box::Dbx, then they will encounter a downgrade of Mail::Reporter because Mail::Box::Dbx would come from MARKOV/Mail-Box-2.120.tar.gz together with an old Mail::Reporter. Do you have any ideas how to prevent that in the future? One way to make sure it won't happen, would be to remove the old versions from the CPAN. Another would be to never abandon namespaces. Not sure what is worse:) Anyhow, I'd like to bring this to you attention. Regards from Berlin,

Dearest upper guru, Mail-Message-3 is not compatible with Mail-Box-2: in the 3* generation, I have split the huge Mail-Box (v2) suite into 4 separate (v3) packages. Mail::Reporter's new location is Mail::Message. The 2* is still on CPAN to help people which still you the old set-up... (besides dependencies, there are no implementation differences) Show quoted text

When I look at 02packages, I see that Mail::Reporter is only included in the correct distribution. The namespace is not abandoned. So, I do not see the issue you described.

The problem is there despite the index seems to favor the newer version. I repeat the story I wrote in the issue above, with some more redundancy thrown in: - a user first installs Mail::Message (so gets MARKOV/Mail-Message-3.008.tar.gz) - and later installs, say, Mail::Box::Dbx (so gets MARKOV/Mail-Box-2.120.tar.gz) - then they will encounter a downgrade of Mail::Reporter because MARKOV/Mail-Box-2.120.tar.gz has an older Mail::Reporter. This will probably not happen but it could. I'm intending to release a version of CPAN.pm that helps to prevent this from happening. But I thought I should let you know that this sort of problem exists before the CPAN.pm users do. -- andreas

Wait, I see the problem. Mail::Box::Dbx has been removed from Mail::Box. You can only install an older version which has it. Show quoted text

I think that PAUSE should remove packages from the index when they removed in newer versions of the same distribution. Mail::Box 3.007 M/MA/MARKOV/Mail-Box-3.007.tar.gz Mail::Box::Collection 3.007 M/MA/MARKOV/Mail-Box-3.007.tar.gz - Mail::Box::Dbx 2.120 M/MA/MARKOV/Mail-Box-2.120.tar.gz - Mail::Box::Dbx::Message 2.120 M/MA/MARKOV/Mail-Box-2.120.tar.gz Mail::Box::Dir 3.007 M/MA/MARKOV/Mail-Box-3.007.tar.gz Maybe I should remove 2.120 as well: I think no-one needs it anymore. -- Thank you for your care!
