fix marshal uninitialized variable warnings (#4114)

2017-10-25T06:09:55+00:00

GCC says:
../cpython/Python/marshal.c: In function ‘PyMarshal_WriteLongToFile’:

This isn't a real problem because if the file pointer is not NULL, the
string-related fields are never touched. But, it doesn't hurt to set the unused
fields to NULL.

reduce marshal stack size in debug mode on windows (closes #27019)

2016-07-07T06:37:02+00:00

Fix reference leaks introduced by the patch for issue #5308.

Issue #5308: Raise ValueError when marshalling too large object (a sequence

2013-02-13T10:07:43+00:00

with size >= 2**31), instead of producing illegal marshal data.

Untabify C files. Will watch buildbots.

Issue #7332: Remove the 16KB stack-based buffer in

2010-04-21T22:53:29+00:00

PyMarshal_ReadLastObjectFromFile, which doesn't bring any noticeable
benefit compared to the dynamic memory allocation fallback.  Patch by
Charles-François Natali.

more _PyString_Resize error checking

2010-04-03T00:57:33+00:00

Set retval on PyOS_string_to_double failure.

2009-10-31T12:47:47+00:00

Removed PyOS_ascii_atof from marshal.c, as mentioned in issue 7117. Also brings it more in line with py3k.

2009-10-27T19:42:57+00:00

Removed calls to PyFloat_AsReprString.

2009-10-19T00:34:12+00:00

This is in anticipation of possibly implementing issue 7117 (short float repr).
This removes the last calls to PyFloat_AsString, PyFloat_AsReprString, and
PyFloat_AsStringEx, which are unsafe.

Also, switch to defines for error values to bring this code more in line
with the py3k branch.
