Do the unit tests pass when you do it? :) (run "trial > twisted".) Well, I get errors: [ERROR]: twisted.test.test_failure exceptions.ImportError: No module named generator_failure_tests [FAIL]: twisted.web.test.test_webclient.WebClientTestCase.testDownloadPageError3twisted.trial.unittest.FailTest: did not catch an error, instead got None [FAIL]: twisted.web.test.test_webclient.WebClientSSLTestCase.testDownloadPageError3 twisted.trial.unittest.FailTest: did not catch an error, instead got None [FAIL]: twisted.test.test_plugin.PluginTestCase.test_deployedMode twisted.trial.unittest.FailTest: not equal: a = 0 b = 1 [FAIL]: twisted.test.test_plugin.DeveloperSetupTests.test_newPluginsOnReadOnlyPath twisted.trial.unittest.FailTest: not equal: a = 0 b = 1 [FAIL]: twisted.test.test_import.AtLeastImportTestCase.test_test exceptions.ImportError: No module named generator_failure_tests I had to run trial as root because otherwise, I get a lot of errors like this: [ERROR]: twisted.trial.test.test_loader.FileTest.test_directory exceptions.OSError: [Errno 13] Permission denied: '/usr/lib/python2.5/site-packages/twisted/trial/test/goodDirectory' [ERROR]: twisted.lore.test.test_lore.TestFactory.test_getProcessorWithFilenameGenerator exceptions.IOError: [Errno 13] Permission denied: '/usr/lib/python2.5/site-packages/twisted/lore/test/simple4.xhtml' [ERROR]: twisted.lore.test.test_lore.TestFactory.test_getProcessor exceptions.IOError: [Errno 13] Permission denied: '/usr/lib/python2.5/site-packages/twisted/lore/test/simple3.xhtml' [ERROR]: twisted.lore.test.test_lore.TestFactory.test_doFile_withFilenameGenerator exceptions.IOError: [Errno 13] Permission denied: '/usr/lib/python2.5/site-packages/twisted/lore/test/simple1.xhtml' [ERROR]: twisted.lore.test.test_lore.TestFactory.test_doFile exceptions.IOError: [Errno 13] Permission denied: '/usr/lib/python2.5/site-packages/twisted/lore/test/simple.xhtml' I suppose that test_deployedMode and test_newPluginsOnReadOnlyPath do not work as root.

Simply packaging these libraries the same way would not > require any special fixes or patches. There is only two packaging system for Python in Debian: python-central and python-support. This solution is then complete. Either the plugins are in /var/lib/python-support/python2.X/twisted/plugins, either they are in /usr/lib/site-packages/python2.X/twisted/plugins. Of course, the user can add twisted/plugins in other directories, but in this case, I think he will arrange to not put __init__.py file in this directory. I think that this patch is the less invasive change that we can do. -- I WON'T NOT USE NO DOUBLE NEGATIVES I WON'T NOT USE NO DOUBLE NEGATIVES I WON'T NOT USE NO DOUBLE NEGATIVES -+- Bart Simpson on chalkboard in episode BABF02
