Summary: test_dumbdbm failing

Initial Comment:
Getting the following failures:



test_close_twice (__main__.DumbDBMTestCase) ... ok

test_dumbdbm_creation (__main__.DumbDBMTestCase) ... 

ok

test_dumbdbm_keys (__main__.DumbDBMTestCase) ... 

ERROR

test_dumbdbm_modification (__main__.DumbDBMTestCase) 

... ERROR

test_dumbdbm_read (__main__.DumbDBMTestCase) ... 

ERROR

test_random (__main__.DumbDBMTestCase) ... ERROR

test_write_write_read (__main__.DumbDBMTestCase) ... 

ERROR





They all error out with the same problem:



Traceback (most recent call last):

  File "Lib/test/test_dumbdbm.py", line 73, in 

test_write_write_read

    f = dumbdbm.open(_fname)

  File "/Users/drifty/Progs/Python/CVS/python/dist/src/Lib/

dumbdbm.py", line 232, in open

    return _Database(file, mode)

  File "/Users/drifty/Progs/Python/CVS/python/dist/src/Lib/

dumbdbm.py", line 73, in __init__

    self._update()

  File "/Users/drifty/Progs/Python/CVS/python/dist/src/Lib/

dumbdbm.py", line 84, in _update

    key, pos_and_siz_pair = eval(line)

TypeError: expected string without null bytes





test_whichdb is also failing for essentially the same reason 

although it is hidden under some executed code:



test_whichdb_dbm (__main__.WhichDBTestCase) ... ok

test_whichdb_dumbdbm (__main__.WhichDBTestCase) ... 

FAIL



=====================================

FAIL: test_whichdb_dumbdbm (__main__.WhichDBTestCase)

Traceback (most recent call last):

  File "Lib/test/test_whichdb.py", line 56, in 

test_whichdb_name

    self.assertEqual(name, whichdb.whichdb(_fname))

  File "/Users/drifty/Progs/Python/CVS/python/dist/src/Lib/

unittest.py", line 292, in failUnlessEqual

    raise self.failureException, \

AssertionError: 'dumbdbm' != None





If I run the test by hand by copy-n-paste in the interpreter I 

get the same error as above about null bytes.



Now I compile with --enable-unicode=ucs4, if that has 

anything to do with it.



This is all on OS X 10.2.6 .

Martin, this appears to be caused by your recent patch to 

fileobject.c and fileobject.h.



FYI, it only fails when run with python_d.
