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 .

This is now fixed in fileobject.c 2.183 and 2.179.8.2.



The bug was triggered by a bug in dumbdbm: the mode argument

does not actually define the file mode, but the buffer size...

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.
