  • Is there anything you've said about BackPAN which does not also apply to CPAN?

    Don't forget, a passive repository is harmless /until/ a human (directly or via a program) intervenes...
    • The big difference being that backpan contains all the files deleted from cpan, and those files were deleted for a reason.
      • Not such a difference.

        To delete V 1.00 because V 1.01 is better makes sense, but you're assuming V 1.01 is perfect, whereas in time CPAN (V 1.01) will be deemed just as faulty because V 1.02 will come along...
        • I'm not assuming anything of the kind. I think you've misunderstood.
          • Nope. But I see further discussion is pointless.
            • I'll rephrase what hex said. Sometimes modules (not just releases) are deleted from CPAN. For a reason.
              • Yes, absolutely. I hadn't thought of that, and it's a very serious addition to the point I was making.
            • Look. My point was, files are removed from CPAN because their replacement either (a) adds something new or (b) fixes something wrong. It's the old files with something wrong that we need to be worried about.

              Your comment about deleting V 1.00 because V 1.01 is better really doesn't have anything to do with the point of my journal entry.

        • I don’t see that assumption anywhere.

          The reason for deleting 1.00 and putting up 1.01 may have been that it is known to have contained a catastrophic bug. Whether or not 1.01 is perfect is irrelevant; we don’t know yet. The point is, we do know, and we know right now, that some fraction of the software on BackPAN is dangerous.

  • Let me introduce you to the Internet Archive [].
  • I think it's a good idea to have a warning, assuming people can stumble onto backpan and not realize that it's an archive meant only for historical record and is not the real CPAN. And I think you're right about the copyright/licensing issues; a module author doesn't necessarily hand over a module to the public domain just because it was uploaded to CPAN, or maybe it should just be explicit that by uploading something to CPAN you forfeit your rights to restrict the module's distribution? (or haven't you?)


    • Personally, I like BackPAN the way it is and wouldn’t want things on it to be deletable forever, because I think of it as an archæological record. The mistakes of the past should conserved with equal prominence to its achievements.

      But it sure would be handy if there was a way to flag known bad stuff so people are forewarned.

      a module author doesn’t necessarily hand over a module to the public domain just because it was uploaded to CPAN

      Well, by uploading to the CPAN, you have distribu

  • You unquestionably have a point. And for licensing reasons, files actually *have* been deleted from the backpan in the past. But this is manually and can be done by admins only. Since this isn't a very frequent occurrence, that's fine in terms of workload and workflow. I'm talking about the semi-official, of course. Everybody could potentially run his own kind of backpan by just copying over anything in the recent submissions to CPAN. There's no controlling that.

    Now, the real value of backp
