| As mentioned on [[Getting]], Launchpad is not currently supported on Ubuntu Karmic Koala, primarily because it currently has a hard dependency on Python 2.4, which is no longer included in Karmic. 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 / Python 2.5 == launchpad-dependencies == First, there is the issue that the ~launchpad PPA doesn't have any packages for Karmic. I (maxb) have tweaked the launchpad-dependencies package to have a first approximation of suitable dependencies for Python 2.5, and uploaded it to my PPA [[https://launchpad.net/~maxb/+archive/ppa]], and copied the geoip-data-city-lite package from the ~launchpad PPA there as well for convenience. == 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 == Launchpad source dependencies - Zope == https://code.launchpad.net/~maxb/zope3/launchpad-3.4-py2.5 contains backports of some changes to zope.proxy and zope.security in post-3.4 Zope releases which are required for Python 2.5 compatibility (possibly only on 64-bit architectures). Without these, Launchpad produces perplexing !MemoryErrors. It also contains a patch to 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 - Twisted == I used to have a Twisted branch mentioned here. It's now obsoleted by the above patch to zope.sendmail. == Test Status == * unit tests: Ran 1328 tests with '''9 failures''' and '''1 errors''' * canonical.testing.layers.!BaseLayer tests: Ran 250 tests with 0 failures and '''1 errors''' * canonical.testing.layers.!LibrarianLayer tests: Ran 8 tests with 0 failures and '''1 errors''' * canonical.testing.layers.!DatabaseLayer tests: Ran 48 tests with 0 failures and '''1 errors''' * canonical.testing.layers.!LaunchpadLayer tests: Ran 23 tests with 0 failures and '''1 errors''' * canonical.testing.layers.!ZopelessLayer tests: Ran 17 tests with 0 failures and '''1 errors''' * canonical.testing.layers.!LaunchpadScriptLayer tests: Ran 72 tests with 0 failures and '''2 errors''' * canonical.testing.layers.!LaunchpadZopelessLayer tests: Ran 3110 tests with '''5 failures''' and '''10 errors''' * canonical.launchpad.ftests.test_system_documentation.!ProcessMailLayer tests: Ran 269 tests with 0 failures and '''1 errors''' * ''canonical.testing.layers.!FunctionalLayer tests: Ran 164 tests with 0 failures and 0 errors'' * canonical.testing.layers.!LaunchpadFunctionalLayer tests: Ran 8116 tests with '''11 failures''' and 0 errors * ''canonical.testing.layers.!AppServerLayer tests: Ran 128 tests with 0 failures and 0 errors'' * canonical.testing.layers.!DatabaseFunctionalLayer tests: Ran 3054 tests with '''1 failures''' and 0 errors * canonical.testing.layers.!PageTestLayer tests: ... * canonical.testing.layers.!TwistedLayer tests: ... * canonical.testing.layers.!TwistedLaunchpadZopelessLayer tests: ... * canonical.testing.layers.!TwistedAppServerLayer tests: ... * canonical.testing.layers.!ZopelessAppServerLayer tests: ... * canonical.testing.layers.!ZopelessDatabaseLayer tests: ... * lp.codehosting.tests.test_acceptance.SSHServerLayer tests: ... == Other Related Work == * Launchpad currently depends on a monolithic Zope source distribution. Zope upstream has since restructured itself as a group of separated modular eggs. Gary Poster is working on migrating Launchpad to this new structure at https://code.launchpad.net/~gary/launchpad/zbuildout - this is a prerequisite to upgrading to newer Zope, which would then avoid the need to cherrypick backports into the existing Zope sourcedep. |
