effde12f5f Speed-up dictionary constructor by about 10%. 
New opcode, STORE_MAP saves the compiler from awkward stack manipulations
and specializes for dicts using PyDict_SetItem instead of PyObject_SetItem.

Old disassembly:
              0 BUILD_MAP                0
              3 DUP_TOP
              4 LOAD_CONST               1 (1)
              7 ROT_TWO
              8 LOAD_CONST               2 ('x')
             11 STORE_SUBSCR
             12 DUP_TOP
             13 LOAD_CONST               3 (2)
             16 ROT_TWO
             17 LOAD_CONST               4 ('y')
             20 STORE_SUBSCR

dfdfaab1c5 Feature #1534 
Added PyFloat_GetMax(), PyFloat_GetMin() and PyFloat_GetInfo() to the float API.
Added a dictionary sys.float_info with information about the internal floating point type to the sys module.

dafd32b730 Issue #1521: on 64bit platforms, str.decode fails on very long strings. 
The t# and w# formats were not correctly handled.

Will backport.

025c347d61 Issue #1402: PyInterpreterState_Clear() may still invoke user code 
(in deallocation of running threads, for example), so the PyGILState_Release()
function must still be functional.
On the other hand, _PyGILState_Fini() only frees memory, and can be called later.

Backport candidate, but only after some experts comment on it.

ffcd1e10b6 Added filename to compiling struct based on Martin's suggestion. 
I'm wonder why I was trying to add the filename to the node all the time. The compiling struct is more obvious.

02c9ab568d Fixed problems in the last commit. Filenames and line numbers weren't reported correctly. 
Backquotes still don't report the correct file. The AST nodes only contain the line number but not the file name.

e8954f8ce7 Backport of the PCbuild9 directory from the py3k branch. 
I've finished the last task for the PCbuild9 directory today. I don't think there is much left to do. Now you can all play around with the shiny new VS 2008 and try the PGO builds. I was able to get a speed improvement of about 10% on py3k.
Have fun! :)

327a39b047 Patch #1739468: Directories and zipfiles containing __main__.py are now executable 2007-11-18 11:56:28 +00:00

0d75f09177 Merge from py3k branch: 
Correction for issue1265 (pdb bug with "with" statement).

When an unfinished generator-iterator is garbage collected, PyEval_EvalFrameEx
is called with a GeneratorExit exception set.  This leads to funny results
if the sys.settrace function itself makes use of generators.
A visible effect is that the settrace function is reset to None.
Another is that the eventual "finally" block of the generator is not called.

It is necessary to save/restore the exception around the call to the trace
function.

This happens a lot with py3k: isinstance() of an ABCMeta instance runs
    def __instancecheck__(cls, instance):
        """Override for isinstance(instance, cls)."""
        return any(cls.__subclasscheck__(c)
                   for c in {instance.__class__, type(instance)})
which lets an opened generator expression each time it returns True.

Backport candidate, even if the case is less frequent in 2.5.

1e534b5425 Fix a crasher where Python code managed to infinitely recurse in C code without 
ever going back out to Python code in PyObject_Call().  Required introducing a
static RuntimeError instance so that normalizing an exception there is no
reliance on a recursive call that would put the exception system over the
recursion check itself.

2ef7582b52 Handle errors when generating a warning. 
The value is always written to the returned pointer if getting it was
successful, even if a warning causes an error. (This probably doesn't matter
as the caller will probably discard the value.)

Simplify the implementation of UnicodeError objects:
start and end attributes are now stored directly as

set functions.
