[pypy-issue] [issue1060] datetime.utcfromtimestamp creates datetime objects which crash in __hash__

[Beda Kosata]

New submission from Beda Kosata <beda.kosata at gmail.com>:

When a datetime object is created from a float using the utcfromtimestamp
classmethod, the resulting instance crashes on hash() and is thus unusable in
dict keys, etc.

>> from datetime import datetime
>> x = datetime.utcfromtimestamp(123456789.0)
>> hash(x)

Traceback (most recent call last):
  File "<console>", line 1, in <module>
  File "/opt/pypy-1.8/lib_pypy/datetime.py", line 1882, in __hash__
    return hash(self._getstate()[0])
  File "/opt/pypy-1.8/lib_pypy/datetime.py", line 1897, in _getstate
    us1, us2, us3)
TypeError: expected integer, got float object

Instances created using fromtimestamp() behave as expected. The issue seems
specific to the utc method.
