This is essentially a checkpoint.

Make readonly members defined in C throw an AttributeError on modification. This brings them into sync with Python-level attributes. Fixes bug #1687163.

(There was also a segfault but it disappeared when the tests
stopped erroring out; I presume the segfault is a pre-existing
problem somewhere in a destructor.)

NotImplemented.

(Is this worth backporting to 2.6?  It seems so useful...!)

inappropriately from ``e[0]`` to ``e.message`` instead of ``e.args[0]``.  The
reason it needs to be the last option is the dichotomy of 'message' and 'args':
'message' can be the empty string but args[0] can have a value if more than one
argument was passed.

(A symbol table entry was leaked every time a class was compiled.)

 * make some module variables static to prevent name pollution
 * Add some comments to clarify what's going on and some XXXs to address
 * Add a space after "for" before (
 * exc_value and tb can be NULL in some cases
 * Get working on Windows (I think)

Patch #1680961: remove sys.exitfunc and replace it with a private C API. Also, reimplement atexit in C so it can take advantage of this private API.

Use the local python binary to build the docs, not whatever 'python' is on the PATH (which is probably Python 2.x, and we need 3.x).

incorrectly assuming that err.message was the Py3k way of
writing err[0] in 2.x.  The correct spelling is err.args[0].

import_stmt accept ELLIPSes and DOTs.

(It is still broken w.r.t. the new nonlocal keyword.)

Remove a series of debug prints I accidentally left in test_ast.py.

PyFloat_FromString. (fixes bug #1650903)

The compiler package hasn't been updated yet; test_compiler.py fails.
Otherwise all tests seem to be passing now.  There are no occurrences
of __metaclass__ left in the standard library.
Docs have not been updated.

_seekable.

Daniel Stutzbach (already in) is main author of _fileio.c.

Add a missing forward declaration for PyFileIO_Type. The _fileio module now compiles with --with-pydebug.

to the cowboy way they are currently hacked in).

(see SF#1671314) with small tweaks.
The io module now uses this instead of its own implementation
of the FileIO class, if it can import _fileio.
