_Py_char2wchar() callers usually need the result size in characters. Since it's
trivial to compute it in _Py_char2wchar() (O(1) whereas wcslen() is O(n)), add

namespace if it occurs as a free variable in a nested block. This limitation
of the compiler has been lifted, and a new opcode introduced (DELETE_DEREF).
This sample was valid in 2.6, but fails to compile in 3.x without this change::
>>> def f():
... def print_error():
... print(e)
... try:
... something
... except Exception as e:
... print_error()
... # implicit "del e" here
This sample has always been invalid in Python, and now works::
>>> def outer(x):
... def inner():
... return x
... inner()
... del x
There is no need to bump the PYC magic number: the new opcode is used
for code that did not compile before.

'once_registry'. This is bad as the warnings module had variables named
'defaultaction' and 'onceregistry' which are what people should be looking at
(technically those variables shouldn't be mucked with as they are undocumented,
but we all know better than to believe that isn't happening). So the variables
from _warnings have been renamed to come off as private and to avoid confusion
over what variable should be used.

Call _wfopen() on Windows, or fopen() otherwise. Return the new file object on
success, or NULL if the file cannot be open or (if PyErr_Occurred()) on unicode
error.
* On non-Windows OSes: the constructor accepts bytes filenames
and use surrogateescape for unicode filenames
* On Windows: use GetFileAttributesW() instead of GetFileAttributesA()
setup_context() replaces .pyc or .pyo filename suffix by .py, but it
didn't work if the filename contains a non-ascii character because the
function used the wrong unit for the length (number of characters
instead of the number of bytes).
With this patch, it uses unicode filenames instead of bytes filenames,
to fix the bug and to be fully unicode compliant.

DeprecationWarning is now silent by default.
This was originally suggested by Guido, discussed on the stdlib-sig mailing
list, and given the OK by Guido directly to me. What this change essentially
means is that Python has taken a policy of silencing warnings that are only
of interest to developers by default. This should prevent users from seeing
warnings which are triggered by an application being run against a new
interpreter before the app developer has a chance to update their code.
Closes issue #7319. Thanks to Antoine Pitrou, Ezio Melotti, and Brian Curtin
for helping with the issue.

http://code.google.com/p/data-race-test/wiki/ThreadSanitizer#Binaries pass many
but not all of the Python tests. All of regrtest still passes outside of tsan.
I've implemented part of the C1x atomic types so that we can explicitly mark
variables that are used across threads, and get defined behavior as compilers
advance.
I've added tsan's client header and implementation to the codebase in
dynamic_annotations.{h,c} (docs at
http://code.google.com/p/data-race-test/wiki/DynamicAnnotations).
Unfortunately, I haven't been able to get helgrind and drd to give sensible
error messages, even when I use their client annotations, so I'm not supporting
them.

POSIX systems with a C extension module. This is required in order for
the subprocess module to be made thread safe.
The pure python implementation is retained so that it can continue to be
used if for some reason the _posixsubprocess extension module is not
available.
The unittest executes tests on both code paths to guarantee compatibility.
* Moves PyLong_FromPid and PyLong_AsPid from posixmodule.c into longobject.h.

where the right hand operand is a set of constants, by turning the set into
a frozenset and pre-building it as a constant. The comparison operation
is made against the constant instead of building a new set each time it is
executed (a similar optimization already existed which turned a list of
constants into a pre-built tuple). Patch and additional tests by Dave

Issue #6603: Fix --with-tsc build failures on x86-64 that resulted
from a gcc inline assembler peculiarity. (gcc's "A" constraint
apparently means 'rax or rdx' in 64-bit mode, not edx:eax
or rdx:rax as one might expect.)

in wide builds, avoid storing high unicode characters from source code with surrogates
This is accomplished by decoding with utf-32 instead of utf-16 on all builds.

Fix issue #1590864, multiple threads and fork() can cause deadlocks, by
acquiring the import lock around fork() calls. This prevents other threads
from having that lock while the fork happens, and is the recommended way of
dealing with such issues. There are two other locks we care about, the GIL
and the Thread Local Storage lock. The GIL is obviously held when calling
Python functions like os.fork(), and the TLS lock is explicitly reallocated
instead, while also deleting now-orphaned TLS data.
This only fixes calls to os.fork(), not extension modules or embedding
programs calling C's fork() directly. Solving that requires a new set of API
functions, and possibly a rewrite of the Python/thread_*.c mess. Add a
warning explaining the problem to the documentation in the mean time.
This also changes behaviour a little on AIX. Before, AIX (but only AIX) was
getting the import lock reallocated, seemingly to avoid this very same
problem. This is not the right approach, because the import lock is a
re-entrant one, and reallocating would do the wrong thing when forking while
holding the import lock.
Will backport to 2.6, minus the tiny AIX behaviour change.
