From b57f8f02bafcb74cd6c47f59f67d1b6bdfb33aec Mon Sep 17 00:00:00 2001 From: Tim Peters Date: Sat, 1 Feb 2003 02:54:15 +0000 Subject: There's no good reason for datetime objects to expose __getstate__() anymore either, so don't. This also allows to get rid of obscure code making __getnewargs__ identical to __getstate__ (hmm ... hope there wasn't more to this than I realize!). --- Lib/test/test_datetime.py | 12 ---------- Misc/NEWS | 4 ++-- Modules/datetimemodule.c | 56 ++++------------------------------------------- 3 files changed, 6 insertions(+), 66 deletions(-) diff --git a/Lib/test/test_datetime.py b/Lib/test/test_datetime.py index 73db033..f383d7b 100644 --- a/Lib/test/test_datetime.py +++ b/Lib/test/test_datetime.py @@ -278,8 +278,6 @@ class TestTimeDelta(unittest.TestCase): def test_pickling(self): args = 12, 34, 56 orig = timedelta(*args) - state = orig.__getstate__() - self.assertEqual(args, state) for pickler, unpickler, proto in pickle_choices: green = pickler.dumps(orig, proto) derived = unpickler.loads(green) @@ -832,8 +830,6 @@ class TestDate(unittest.TestCase): def test_pickling(self): args = 6, 7, 23 orig = self.theclass(*args) - state = orig.__getstate__() - self.assertEqual(state, ('\x00\x06\x07\x17',), self.theclass) for pickler, unpickler, proto in pickle_choices: green = pickler.dumps(orig, proto) derived = unpickler.loads(green) @@ -1186,8 +1182,6 @@ class TestDateTime(TestDate): def test_pickling(self): args = 6, 7, 23, 20, 59, 1, 64**2 orig = self.theclass(*args) - state = orig.__getstate__() - self.assertEqual(state, ('\x00\x06\x07\x17\x14\x3b\x01\x00\x10\x00',)) for pickler, unpickler, proto in pickle_choices: green = pickler.dumps(orig, proto) derived = unpickler.loads(green) @@ -1567,8 +1561,6 @@ class TestTime(unittest.TestCase): def test_pickling(self): args = 20, 59, 16, 64**2 orig = self.theclass(*args) - state = orig.__getstate__() - self.assertEqual(state, ('\x14\x3b\x10\x00\x10\x00',)) for pickler, unpickler, proto in pickle_choices: green = pickler.dumps(orig, proto) derived = unpickler.loads(green) @@ -1877,8 +1869,6 @@ class TestTimeTZ(TestTime, TZInfoBase): # Try one without a tzinfo. args = 20, 59, 16, 64**2 orig = self.theclass(*args) - state = orig.__getstate__() - self.assertEqual(state, ('\x14\x3b\x10\x00\x10\x00',)) for pickler, unpickler, proto in pickle_choices: green = pickler.dumps(orig, proto) derived = unpickler.loads(green) @@ -2080,8 +2070,6 @@ class TestDateTimeTZ(TestDateTime, TZInfoBase): # Try one without a tzinfo. args = 6, 7, 23, 20, 59, 1, 64**2 orig = self.theclass(*args) - state = orig.__getstate__() - self.assertEqual(state, ('\x00\x06\x07\x17\x14\x3b\x01\x00\x10\x00',)) for pickler, unpickler, proto in pickle_choices: green = pickler.dumps(orig, proto) derived = unpickler.loads(green) diff --git a/Misc/NEWS b/Misc/NEWS index c0aa976..5d3f57c 100644 --- a/Misc/NEWS +++ b/Misc/NEWS @@ -131,8 +131,8 @@ Extension modules The pickle format of date, time and datetime objects has changed completely.
