backpan cache refresh for Mail::Chimp2

[norbu09]

Metacpan shows versions of Mail::Chimp2 that are not on backpan.

Please refresh the cache.

Please confirm the names of the tarballs which should be removed.

[norbu09]

the two archives are:

https://metacpan.org/source/NORBU/Mail-Chimp2-0.4
https://metacpan.org/source/NORBU/Mail-Chimp2-0.3

@andreeap We'll want to add a script to handle this. You can look at lib/MetaCPAN/Script for examples. The script will need to do the following:

• Maintain a list of blacklisted tarballs + author names
• Delete these files from our local CPAN if they exist there
• Delete any files which belonged to this release from the following endpoints:
  • file
  • release

So basically we'll hardcode the blacklisted archives in this script. There won't be many of them, but they could re-appear at any point after a sync, so we need to make sure we kill them if they ever re-appear.

You should write and test the code on your Vagrant VM. Once that is done, we can test this on a staging box to make sure only the right things get deleted. :)

@andreeap: I'd like to work on this issue if that's OK. I have a dist that needs to be removed ASAP.

@mjgardner Please go ahead, we will need something that can run in cron and take a list of files, I started andk/pause#144 to centralise that, but for now a local file, containing the list would be enough.

Deleted files are communicated the same way as added and changed files: File-Rsync-Mirror-Recent. The collection of "RECENT" files has them. The script should not have more than a few lines. But metacpan maybe wants to implement a policy how to translate the fact about a deletion to an actual deletion.

Thanks, @andk. We do track deletes because we need to know when to move a module's status from "cpan" or "latest" to "backpan". Having said that, we don't know how to differentiate a "delete but keep a copy in BackPAN" from a "permanently delete from CPAN and BackPAN".

andk/pause#144 was an idea to be able to centralise "permanently delete from CPAN and BackPAN"
