[Bug 597041] Re: No way to get from binary package to source package

[Łukasz Zemczak]

Hi Colin!

Regarding your proposition in comment #4:
Archive.getPublishedSources(binary_name=...) would work perfectly for my
needs at least. It seems error proof and I could do the rest of
validation myself to be sure that it's the source package that I'm
actually interested in. Are there any plans on getting something like
this implemented soon? I know it's a low priority issue, but would be
nice to have something like that in the LP API. I could finally remove
those multiple hacks in all my analysis tools that do the binary ->
source conversion.

Thanks!

Title:
  No way to get from binary package to source package

Status in Launchpad itself:
  Triaged
Status in python-launchpadlib package in Ubuntu:
  Invalid

Bug description:
  Binary package hint: python-launchpadlib

  This is basically the same bug as bug #53171, but for the Launchpad
  API:

  There should be a way to either determine the "source_package" object
  or the "source_package_publishing_history" object when having a
  "binary_package_publishing_history" object.

  One could (for example) parse the launchpad page
  https://launchpad.net/ubuntu/maverick/i386/libgtk2.0-0 for the link to
  https://launchpad.net/ubuntu/+source/gtk+2.0 or run "dpkg-query -W
  -f='${Source}' libgtk2.0-0", but a API call would be very handy.

  Some attribute like "source_package_name" would also suffice, but
  "getSourcePackage()" or "getSourcePackagePublishingHistory()" would be
  really great.
