Jeffrey Yasskin 9871d8fe22 Continue rolling back pep-3141 changes that changed behavior from 2.5. This
round included:
 * Revert round to its 2.6 behavior (half away from 0).
 * Because round, floor, and ceil always return float again, it's no
   longer necessary to have them delegate to __xxx___, so I've ripped
   that out of their implementations and the Real ABC. This also helps
   in implementing types that work in both 2.6 and 3.0: you return int
   from the __xxx__ methods, and let it get enabled by the version
   upgrade.
 * Make pow(-1, .5) raise a ValueError again.

Guido van Rossum 3b83549ea0 Patch #1725 by Mark Dickinson, fixes incorrect conversion of -1e1000
and adds errors for -0x.

Christian Heimes 123d5c9396 Moved include "Python.h" in front of other imports to silence a warning. 2008-01-04 03:15:05 +00:00
Amaury Forgeot d'Arc e0b7695286 Partial port of r59682 from py3k.
On Windows, when import fails to load a dll module, the message says
"error code 193" instead of a more informative text.

It turns out that FormatMessage needs additional parameters for some error codes.
For example: 193 means "%1 is not a valid Win32 application".
Since it is impossible to know which parameter to pass, we use
FORMAT_MESSAGE_IGNORE_INSERTS to get the raw message, which is still better
than the number.

Christian Heimes 000a074c95 Modified PyImport_Import and PyImport_ImportModule to always use absolute imports by calling __import__ with an explicit level of 0
Added a new API function PyImport_ImportModuleNoBlock. It solves the problem with dead locks when mixing threads and imports
2008-01-03 22:16:32 +00:00
Jeffrey Yasskin 2f3c16be73 Backport PEP 3141 from the py3k branch to the trunk. This includes r50877 (just
the complex_pow part), r56649, r56652, r56715, r57296, r57302, r57359, r57361,
r57372, r57738, r57739, r58017, r58039, r58040, and r59390, and new
documentation. The only significant difference is that round(x) returns a float
to preserve backward-compatibility. See http://bugs.python.org/issue1689.

Guido van Rossum 01dbc109a8 Improve performance of built-in any()/all() by avoiding PyIter_Next() --

Christian Heimes e93237dfcc #1629: Renamed Py_Size, Py_Type and Py_Refcnt to Py_SIZE, Py_TYPE and Py_REFCNT. Macros for b/w compatibility are available. 2007-12-19 02:37:44 +00:00

Christian Heimes 0a8143f646 Applied patch #1635: Float patch for inf and nan on Windows (and other platforms).
The patch unifies float("inf") and repr(float("inf")) on all platforms.

Raymond Hettinger fd7ed407d7 Give meaning to the oparg for BUILD_MAP: estimated size of the dictionary.
Allows dictionaries to be pre-sized (upto 255 elements) saving time lost
to re-sizes with their attendant mallocs and re-insertions.

Has zero effect on small dictionaries (5 elements or fewer), a slight
benefit for dicts upto 22 elements (because they had to resize once
anyway), and more benefit for dicts upto 255 elements (saving multiple
resizes during the build-up and reducing the number of collisions on
the first insertions).  Beyond 255 elements, there is no addional benefit.

Raymond Hettinger 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.

Raymond Hettinger 4e2f714031 Fix Issue 1045.
Factor-out common calling code by simplifying the length_hint API.
Speed-up the function by caching the PyObject_String for the attribute lookup.

Christian Heimes 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.
2007-12-01 11:20:10 +00:00
Amaury Forgeot d'Arc dafd32b730 Issue #1521: on 64bit platforms, str.decode fails on very long strings.
The t# and w# formats were not correctly handled.

Will backport.
2007-11-30 20:51:40 +00:00
Amaury Forgeot d'Arc 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.

Christian Heimes 28104c58d2 Expose Py_Py3kWarningFlag as sys.py3kwarning as discussed in #1504

Christian Heimes 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.
2007-11-24 01:36:02 +00:00
Christian Heimes 6d8fb1a444 And yet another fix for the patch. Paul Moore has send me a note that I've missed a declaration. The additional code has moved the declaration in the middle of the block. 2007-11-23 13:25:31 +00:00
Christian Heimes e36fe53d68 How did the comment get there? 2007-11-23 12:16:35 +00:00
Christian Heimes 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.

Christian Heimes 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! :)

Nick Coghlan 327a39b047 Patch #1739468: Directories and zipfiles containing __main__.py are now executable 2007-11-18 11:56:28 +00:00
Amaury Forgeot d'Arc 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.
