Alexandre Vassalotti fc91285c93 Remove code path in cpickle that does not exist in pickle. 2013-11-24 03:07:35 -08:00
Alexandre Vassalotti c49477b184 Make Ellipsis and NotImplemented picklable through the reduce protocol. 2013-11-24 02:53:45 -08:00
Alexandre Vassalotti 4c05d3bc56 Make built-in methods picklable through the reduce protocol. 2013-11-24 02:41:05 -08:00
Alexandre Vassalotti b6a2f2a0d1 Make framing optional in pickle protocol 4.
This will allow us to control in the future whether to use framing or not.
For example, we may want to turn it off for tiny pickle where it doesn't
help.

The change also improves performance slightly:

and warns about potential uninitialized use.

The following code didn't handle correctly the failure of

if (newobj_str == NULL) {
    newobj_str = PyUnicode_InternFromString("__newobj__");
    name_str = PyUnicode_InternFromString("__name__");
    if (newobj_str == NULL || name_str == NULL)

Victor Stinner 68c8ea25f1 Issue #18408: Fix _Pickler_New() and _Unpickler_New(): initialize all

_Pickler_New() now calls PyObject_GC_Del() instead of Py_DECREF() on error,
because the pickle object is created using PyObject_GC_New().

Fix a crash in the destructor when an attribute is not initiallized.

Alexandre Vassalotti 7c5e094cbf Make C and Python implementations of pickle load STRING opcodes the same way.
The C version tried to remove trailing whitespace between the last quote and
the newline character. I am not sure why it had this because pickle never
generated such pickles---for this to happen repr(some_string) would need to
return trailing whitespace. It was maybe there to make it easier for people
to write pickles in text editors. Anyhow, the Python version doesn't do this
so there is no point keeping this around anymore.

Also, I've changed the exception raised when a bad pickle is encountered.
Again this unlikely to make much difference to anyone though it does make
testing slightly nicer for us.
