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 developing Launchpad on Karmic.

You'll need to fetch https://code.launchpad.net/~maxb/lp-source-dependencies/python2.5 instead of the trunk, 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.		 ##REMOVED (temporarily? permanently?) * Increased timeout for starting test Librarian - don't know if this is still needed

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

It has also become slightly co-opted as a place to manage the migration towards compatibility with the newer Python versions which Karmic prefers by default.

PPA Dependencies

The Launchpad PPA now contains a complete set of packages for the Karmic series.

Launchpad on Karmic with Python 2.4

It works pretty much, but there's an unresolved issue wherein setuptools' way of supporting Python namespace packages tends to leave you using the lazr.* packages installed into the system site-packages directory, despite the Launchpad buildout's best efforts.

This manifests as the following test failures:

  • Problems importing lazr.enum:

    • lp.codehosting.puller.tests.test_scheduler.TestPullerMasterIntegration.test_mirror

    • lp.codehosting.puller.tests.test_scheduler.TestPullerMasterIntegration.test_mirror_with_destination_self_locked

    • lp.codehosting.puller.tests.test_acceptance.TestBranchPuller.test_hosted_branch_stacked_on_mirrored_branch

    • lp.codehosting.puller.tests.test_acceptance.TestBranchPuller.test_manual_stacking

    • lp.codehosting.puller.tests.test_acceptance.TestBranchPuller.test_mirror_hosted_branch

    • lp.codehosting.puller.tests.test_acceptance.TestBranchPuller.test_mirror_hosted_loom_branch

    • lp.codehosting.puller.tests.test_acceptance.TestBranchPuller.test_mirror_imported_branch

    • lp.codehosting.puller.tests.test_acceptance.TestBranchPuller.test_mirror_mirrored_branch

    • lp.codehosting.puller.tests.test_acceptance.TestBranchPuller.test_mirror_private_branch

    • lp.codehosting.puller.tests.test_acceptance.TestBranchPuller.test_remirror_hosted_branch

    • lp.codehosting.puller.tests.test_acceptance.TestBranchPuller.test_stack_mirrored_branch

    • lp.codehosting.puller.tests.test_acceptance.TestBranchPuller.test_stack_mirrored_branch_onto_private

    • lp.services.scripts.tests.test_all_scripts.ScriptsTestCase.test_scripts

  • Unicode vs. bytestring issues:
    • eggs/launchpadlib-1.5.1-py2.4.egg/launchpadlib/docs/people.txt
    • eggs/launchpadlib-1.5.1-py2.4.egg/launchpadlib/docs/toplevel.txt

Workaround: Remove the symlinks at /usr/lib/python2.{4,5}/site-packages/lazr.*-nspkg.pth and trust to the fact that Karmic's default Python is 2.6 to hopefully not break anything on your system that wanted to use them.

Moving to newer Python versions: 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 tracks lp:launchpad/stable (or occasionally devel), on a manual basis, and acts as a one-stop-shop for something that people can check out and build using Python 2.5

Remaining changes in python2.5 branch:

  • Changed PYTHON_VERSION in Makefiles

  • Changed shebang in cronscripts/*, scripts/*,

Launchpad source dependencies (sourcecode bzr trees)

The Makefiles of pygettextpo & pygpgme make direct reference to Python 2.4, you'll need to amend them appropriately.
