Can you be more specific?
Only with an insane amount of work. I'll hold that off for a while.
I don't know if this is related at all (and I guess we won't until
Lennart can be more specific :), but here are some Twisted unit test
failures which are probably due to unittest changes in 2.7:
===============================================================================
[FAIL]: twisted.trial.test.test_loader.LoaderTest.test_sortCases
Traceback (most recent call last):
File
"/home/buildslave/pybot/trunk.glass-x86/build/Twisted/twisted/trial/test/test_loader.py",
line 167, in test_sortCases
[test._testMethodName for test in suite._tests])
twisted.trial.unittest.FailTest: not equal:
a = ['test_b', 'test_c', 'test_a']
b = ['test_c', 'test_b', 'test_a']
Is the order significant? Can you just compare sorted versions of the
lists instead?
If the order *is* significant I would be interested to know which change
caused this.
===============================================================================
[FAIL]: twisted.trial.test.test_loader.ZipLoadingTest.test_sortCases
Traceback (most recent call last):
File
"/home/buildslave/pybot/trunk.glass-x86/build/Twisted/twisted/trial/test/test_loader.py",
line 167, in test_sortCases
[test._testMethodName for test in suite._tests])
twisted.trial.unittest.FailTest: not equal:
a = ['test_b', 'test_c', 'test_a']
b = ['test_c', 'test_b', 'test_a']
Ditto.
===============================================================================
[FAIL]: twisted.trial.test.test_tests.TestSkipMethods.test_reasons
Traceback (most recent call last):
File
"/home/buildslave/pybot/trunk.glass-x86/build/Twisted/twisted/trial/test/test_tests.py",
line 143, in test_reasons
str(reason))
twisted.trial.unittest.FailTest: not equal:
a = 'skip1 (twisted.trial.test.test_tests.SkippingTests)'
b = 'skip1'
===============================================================================
[FAIL]: twisted.trial.test.test_class.AttributeSharing.test_shared
Traceback (most recent call last):
File
"/home/buildslave/pybot/trunk.glass-x86/build/Twisted/twisted/trial/test/test_class.py",
line 131, in test_shared
'test_2')
twisted.trial.unittest.FailTest: not equal:
a = 'test_2 (twisted.trial.test.test_class.ClassAttributeSharer)'
b = 'test_2'
These two test failures are due to the change in repr of something I
guess? Is a or b the original output?
===============================================================================
I'm not opposed to the improvement of unittest (or any part of
Python). Perhaps more of the improvements can be provided in new APIs
rather than by changing the behavior of existing APIs, though.
Well, introducing lots of new APIs has its own problems of course.
Hearing about difficulties changes cause is good though (the reason for
alphas I guess) and if it is possible to work out why things are broken
then maybe we can still have the new functionality without the breakage.
The problem with Lennart's report is that it is just "things are broken"
without much clue. I am sympathetic to this (working out *exactly* what
is broken in someone else's code can be a painful chore) but I'm not
sure what can be done about it without more detail.
All the best,
Michael
