Hi I have been testing out pypy for the first time... I wanted to get the datetime module working and found that there was a pure python implementation of it done before the C implementation, in the nondist/sandbox/datetime module on Python CVS. This implementation works fairly well on pypy: - in order to test it, the attached patch to test_datetime is needed to avoid problems with pickle and gc - other than pickling, the only test failures are below The datetime.py can be got directly here: http://cvs.sourceforge.net/viewcvs.py/*checkout*/python/python/nondist/sandbox/datetime/datetime.py?content-type=text%2Fplain&rev=1.160 ====================================================================== ERROR: test_combine (__main__.TestDateTime) ---------------------------------------------------------------------- Traceback (most recent call last): File "test_datetime.py", line 1396, in test_combine dt = combine(time=t, date=d) TypeError: newfunc() got 2 unexpected keyword arguments ====================================================================== ERROR: test_more_astimezone (__main__.TestDateTimeTZ) ---------------------------------------------------------------------- Traceback (most recent call last): File "test_datetime.py", line 2636, in test_more_astimezone dt = self.theclass.now(tz=f44m) TypeError: newfunc() got an unexpected keyword argument 'tz' ====================================================================== ERROR: test_tzinfo_fromtimestamp (__main__.TestDateTimeTZ) ---------------------------------------------------------------------- Traceback (most recent call last): File "test_datetime.py", line 2423, in test_tzinfo_fromtimestamp again = meth(ts, tz=off42) TypeError: newfunc() got an unexpected keyword argument 'tz' ====================================================================== ERROR: test_tzinfo_now (__main__.TestDateTimeTZ) ---------------------------------------------------------------------- Traceback (most recent call last): File "test_datetime.py", line 2385, in test_tzinfo_now again = meth(tz=off42) TypeError: newfunc() got an unexpected keyword argument 'tz' ====================================================================== FAIL: test_subclass_timedelta (__main__.TestTimeDelta) ---------------------------------------------------------------------- Traceback (most recent call last): File "test_datetime.py", line 469, in test_subclass_timedelta self.assert_(type(t3) is timedelta) File "/share/sjsoft/code/Python/pypy/dist-pypy/lib-python-2.3.4/unittest.py", line 278, in failUnless if not expr: raise self.failureException, msg AssertionError David
