ctypedbytes's Issues

Python 2.4 compatibility

The current fastb.c code is not compatible with Python < 2.5. I'm stuck with Python 2.4 on my Hadoop cluster :-(. The following diff fixes the extension. (I'm not configuring it as a fork/pull because it's so simple.)

See http://bugs.python.org/issue1485576 for a discussion

longs not read properly

It’s currently not caught by the unit tests, but after adding .reads() (in order to avoid falling back to the pure-Python typedbytes module) in tests/testio.py you get:

Failure in test testio (tests.testio.TestIO) 
Traceback (most recent call last):
  File "/usr/lib/python2.6/unittest.py", line 279, in run
    testMethod()
  File "/mir/klaas/gits/ctypedbytes/tests/testio.py", line 23, in testio
    self.assertEqual(objects[index], record)
  File "/usr/lib/python2.6/unittest.py", line 350, in failUnlessEqual
    (msg or '%r != %r' % (first, second))
AssertionError: 3000000000 != -1294967296L

Hence, longs are not read properly by the implementation in C.
