Enable uploads to post-release pockets in PPA

snippet from the launchpad-users mailing list: https://lists.ubuntu.com/archives/launchpad-users/2007-October/002471.html where alternatives have been exposed by Celso Providelo.

He means that PPA packages are built with dependencies coming only
from 'release' pocket.

We can solve this problem in two different ways:

 1. Enable uploads to post-release pockets in PPA. They would use the
respective (and maintained) ubuntu chroots and get build-deps
according the target pocket.

 2. Wait for 'archive_purpose-specific-chroots' implementation, when
we will be able to customize the 'release' chroot for PPA to grab
build-deps from post-release pockets.

The former would represent more complexity to the PPA-owners, in the
sense they will have to coordinate uploads across pockets, and no
extra work for ubuntu-admins.

The latter solution is exactly the opposite, PPA-owners won't notice
any drawback in their workflow and would get post-release build-deps
for free, but ubuntu-admins will have to maintain a parallel chroot
for PPAs.

Another major side-effect of the second solution is that PPA users
(clients) will have to enable all post-release pockets in their
systems in other to install possible binary-dependencies required in
PPA packages.

It's a complicated decision.

As I mentioned in the lp-user@ message, it's a tough decision and we have to consult the involve parts to see what they prefer (ubuntu-team, buildd-admins, etc).

Is there any way I can help submitting the topic for discussion to other stakeholders? ... just to be sure it gets addressed someday...

Sure, you can point ubuntu-motu and other PPA users to this bug and collect suggestion, ideas, impacts of the proposed solution ... if you have time.

From my side, I can only say that we won't have time to address it before LP 1.1.11 (5 ~ 6 weeks), sorry :(.

PPA builds already use the Ubuntu chroots and will also use the same pocket dependencies as builds in the Ubuntu archive. In addition, PPA builds do not use the ogre model for components and can build against dependencies in any component in the primary archve. Therefore, I don't see any problems here and am marking this bug accordingly.

This bug has been reported on the Ubuntu ISO testing tracker.
