As mentioned on Getting, Launchpad is not currently supported on Ubuntu Karmic Koala.

This page is a place to collect notes written for and by people living on the bleeding edge and attempting to get Launchpad working on Karmic.

Phase 1 - Python 2.4

Phase 1 is to get it working on Karmic using Python 2.4 - this requires rebuilding quite a few Python module packages, as Python 2.4 is not a supported Python version in Karmic. These packages are in my PPA for Launchpad-related packages https://launchpad.net/~maxb/+archive/launchpad and are mostly synced into the official Launchpad PPA.

Status: some test failures

• canonical.testing.layers.LaunchpadZopelessLayer tests:

  • lp.archiveuploader.tests.test_ppauploadprocessor.TestPPAUploadProcessor.testPPAUploadResultingInNoBuilds - FatalUploadError: Unable to find mandatory field 'files' in the changes file.

  • lp.archiveuploader.tests.test_uploadprocessor.TestUploadProcessor.testUploadResultingInNoBuilds - FatalUploadError: Unable to find mandatory field 'files' in the changes file.

  • lp.soyuz.tests.test_packageupload.PackageUploadTestCase.test_realiseUpload_for_delayed_copies - AssertionError: <DBItem PackageUploadStatus.DONE, (3) Done> != <DBItem PackageUploadStatus.ACCEPTED, (2) Accepted>

    • wgrant can't reproduce this on karmic i386

• canonical.testing.layers.LaunchpadFunctionalLayer tests:

  • lib/canonical/launchpad/ftests/../doc/canonical_url_examples.txt - http://launchpad.dev/+groups vs. http://translations.launchpad.dev/+groups

Once it becomes possible to run the testsuite successfully with Python 2.4 on Karmic, we move on to phase 2...

Phase 2 - Python 2.5

The ultimate goal is to migrate Launchpad to Python 2.6. Rather than go straight to Python 2.6, I (maxb) am focusing on Python 2.5 first as a stepping stone.

Launchpad code itself

https://code.launchpad.net/~maxb/launchpad/python2.5 contains a few fixes:

• Adjusting the Python version in the Makefiles
• Adjusting import statements to handle the built-in location of cElementTree in Python 2.5
• Making buildmailman.py compatible with Python 2.5 sys.path_importer_cache behaviour

• Fixing Launchpad's TestCase subclass for method renames in unittest in Python 2.5

• etc...

Launchpad source dependencies - Zope

Thanks to the completion and landing of Gary's zbuildout branch, the zope branch previously listed here is now obsolete.

However, you'll now need to fetch https://code.launchpad.net/~maxb/lp-source-dependencies/python2.5, for a patched version of zope.sendmail, working around a change in the ordering of atexit vs. waiting for non-main non-daemon threads to shut down which otherwise caused various Python processes to hang on shutdown.

Launchpad source dependencies - pygettextpo & pygpgme

The Makefiles of these two make direct reference to Python 2.4, you'll need to amend them appropriately.
