Merge lp:~ursinha/ubuntu-dev-tools/fix_getBinaryPackage into lp:~ubuntu-dev/ubuntu-dev-tools/trunk

[Ursula Junque]

Fixed the behavior of getBinaryPackage in lpapicache.py. It was using the same parameters to get Source and Binary packages build history, but source packages need a distro series, and binary packages need a distro arch series, the results are arch dependent. I've added a DistroArchSeries, and changed DistroSeries accordingly. Also added a method to get binaryFileUrls.

[Brian Murray (brian-murray)]

This looks good however, shouldn't archtag=None here:

68 + def getBinaryPackage(self, name, archtag, series=None, pocket=None):

As distro_arch_series is not required by Launchpad.

While a nitpick the following should be an not a:

17 + Returns a DistroSeries object for a architecture passed by name (e.g.

ubuntutools/lp/lpapicache.py: removed archtag as required in getBinaryPackage.

[Ursula Junque (ursinha)]

I've made archtag not required, and workarounded the code so _getPublishedItem will use distro_arch_series parameter instead of distro_series when calling getBinaryPackage (that is the bug that motivated this fix).
