[Bug 1174797] Re: Canonical repos with Suite!=Codename cannot be mirrored

[David Medberry]

Precise SRU

[Impact]

This debmirror defect prevents users of stable releases from mirroring
certain ubuntu archives to minimize their network usage. In particular,
it forces users of clouds to REPEATEDLY exit the cloud at network
expense to archive ubuntu-cloud.archive.canonical.com (the repository
used to put newer versions of openstack on precise.)

The upload simply adds a special case for "Origin:Canonical" ubuntu
archives to be treated in the same way as "Origin:Ubuntu" archives and
the rest of the rules/logic remains the same.

[Test Case]

 * Reproduce:
 debmirror --debug --rsync-extra=none --host=ubuntu-cloud.archive.canonical.com --method=http --dist=precise-updates/folsom --section=main --arch=amd64,i386 --nosource --no-check-gpg  DIRNAME

In the error message, a tell-tale sign of the bug is a recursive
"folsom"

[Regression Potential]

 * discussion of how regressions are most likely to manifest as a result of this change. 
I don't foresee a regression unless we create NEW archives under a new Origin: ThereBeDragons at which point we may end up in the same situation. The folks involved with the Origin naming are subscribed to this bug. It seems unlikely this will recur.


[Other Info]
 
 * Tested against the Origin:Canonical repository (works), tested against Origin: Ubuntu (didn't break), tested against Origin: Debian (didn't break)

Title:
  Canonical repos with Suite!=Codename cannot be mirrored

Status in “debmirror” source package in Precise:

Bug description:
  Imported from Debian bug http://bugs.debian.org/702319:

  Package: debmirror
  Version: 1:2.14

  In sub "name_release" Release files with "Origin: Canonical"
  should be treated like those with "Origin: Ubuntu". Otherwise
  mirroring of some Canonical repos is not possible.
  Prominent example:
  ubuntu-cloud.archive.canonical.com with dist=precise-updates/folsom

  Would be glad, if this were fixed!

  Thanks
  Fabian
