  r84209 | amaury.forgeotdarc | 2010-08-19 19:43:15 +0200 (jeu., 19 août 2010) | 5 lines

  Check the return values for all functions returning an ast node.
  Failure to do it may result in strange error messages or even crashes,
  in admittedly convoluted cases that are normally syntax errors, like:
      def f(*xx, __debug__): pass
........
  r84214 | amaury.forgeotdarc | 2010-08-19 23:32:38 +0200 (jeu., 19 août 2010) | 3 lines

  Add tests for r84209 (crashes in the Ast builder)
  Also remove one tab, and move a check closer to the possible failure.

fa84d923ec Remove two unneeded branches to an 'if' statement by applying De Morgan's Law 
and creating a single 'if' statement along with a NULL default value for a
variable.

Also clean up a bunch of whitespace.

Found using Clang's static analyzer.

99a5023c80 improve several corner cases related with argument names in parenthesis 
- Fix #7362: give a good error message for parenthesized arguments with
  defaults.

- Add a py3k warning for any parenthesized arguments since those are not allowed
  in Py3.  This warning is not given in tuple unpacking, since that incurs the
  tuple unpacking warning.

ea0e3b0d60 do a backport of r75928 
The added test does not fail without the patch, but we still fix the issue of
surrogates being used in wide builds where they should not be.

944f684ce6 Allow multiple context managers in one with statement, as proposed 
in http://codereview.appspot.com/53094 and accepted by Guido.

The construct is transformed into multiple With AST nodes so that
there should be no problems with the semantics.

9d53457e59 Merge in release25-maint r60793: 
Added checks for integer overflows, contributed by Google. Some are
 only available if asserts are left in the code, in cases where they
 can't be triggered from Python code.

dd96db63f6 This reverts r63675 based on the discussion in this thread: 
http://mail.python.org/pipermail/python-dev/2008-June/079988.html

Python 2.6 should stick with PyString_* in its codebase.  The PyBytes_* names
in the spirit of 3.0 are available via a #define only.  See the email thread.

3c60833e1e Patch #2477: Added from __future__ import unicode_literals 
The new PyParser_*Ex() functions are based on Neal's suggestion and initial patch. The new __future__ feature makes all '' and r'' unicode strings. b'' and br'' stay (byte) strings.

d21fb4c2e0 Issue#2238: some syntax errors from *args or **kwargs expressions 
would give bogus error messages, because of untested exceptions::

    >>> f(**g(1=2))
    XXX undetected error
    Traceback (most recent call last):
      File "<stdin>", line 1, in <module>
    TypeError: 'int' object is not iterable

instead of the expected SyntaxError: keyword can't be an expression

Will backport.
