+request-daily-build oops with an AttributeError: 'NoneType' object has no attribute 'published_archives'

User was attempting to publish to this private ppa:

https://launchpad.net/~oem-solutions-group/+archive/ppa

Rex we need detailed information from you on exactly what you are doing so we can reproduce the problem. I have asked William Grant to contact you on 2011-08-31 on IRC to get more details from you.

I tried it again today, but now it shows "500 Internal Server Error".

Test procedures -
* Open https://code.launchpad.net/~chihchun/+recipe/freerdp-daily-1.0.0
* Click "Request builds"
* Chose "oem:maza" as ppa archive, "natty" for distribution series.
* Click Request Builds, it will return "oops" or "500 Internal Server Error".

22:17:21 <wgrant> So, ViewBuildFarmJobOld is buggy.
22:18:08 <wgrant> _getBuild can return an IBinaryPackageBuild or an ISourcePackageRecipeBuild. But it then passes that build into _checkBuildPermission,
                  which calls ViewBinaryPackageBuild on the build.
22:18:28 <wgrant> In this case it's a SourcePackageRecipeBuild, so ViewBinaryPackageBuild doesn't cope very well.

This bug isn't normally exposed, since ViewBinaryPackageBuild short-circuits if the user is a member of the owning team, and that works fine for SPRBs too. But in this case Rex is trying to request a build into an ~oem-archive PPA, where he isn't the owner but does have upload rights via a custom ArchivePermission. The ownership short-circuit isn't used, and we end up trying to retrieve a SourcePackageRelease from an SPRB.

So, to reproduce: create a private PPA, add an ArchivePermission for yourself, change the owner to a team of which you are not a member, and try to build a recipe into it.

Thanks Rex for the extra info. And thanks William for the insight about ArchivePermission. The fix for this bug will soon be in review.

Fixed in stable r13842 <http://bazaar.launchpad.net/~launchpad-pqm/launchpad/stable/revision/13842>.
