Eric Smith 8113ca63b9 Issue 2264: empty float presentation type needs to have at least one digit past the decimal point.
Added "Z" format_char to PyOS_ascii_formatd to support empty float presentation type.
Renamed buf_size in PyOS_ascii_formatd to more accurately reflect it's meaning.
Modified format.__float__ to use the new "Z" format as the default.
Added test cases.

Mark Dickinson c23b8a7af9 Issue 705836: Fix struct.pack(">f", 1e40) to behave consistently
across platforms:  it should now raise OverflowError on all
platforms.  (Previously it raised OverflowError only on
non IEEE 754 platforms.)

Also fix the (already existing) test for this behaviour
so that it actually raises TestFailed instead of just
referencing it.

Guido van Rossum 5bdff60617 Fix the overflows in expandtabs(). "This time for sure!"

Jeffrey Yasskin 960b9b7a2f Move abc._Abstract into object by adding a new flag Py_TPFLAGS_IS_ABSTRACT,
which forbids constructing types that have it set. The effect is to speed

  ./python.exe -m timeit -s 'import abc' -s 'class Foo(object): __metaclass__ = abc.ABCMeta' 'Foo()'

up from 2.5us to 0.201us. This fixes issue 1762.

Eric Smith 4b051eecb9 Corrected assert to check for correct type in py3k. 2008-02-24 21:41:49 +00:00
Christian Heimes 09bde04154 Use PY_FORMAT_SIZE_T instead of z for string formatting. Thanks Neal. 2008-02-24 12:26:16 +00:00
Facundo Batista c11cecf3d0 Issue 1742669. Now %d accepts very big float numbers.
Thanks Gabriel Genellina.

Georg Brandl ad61bc8d9b #2067: file.__exit__() now calls subclasses' close() method. 2008-02-23 15:11:18 +00:00
Eric Smith 8a803dd94b Now that PyOS_ascii_formatd supports the 'n' format, simplify the float formatting code to just call it. 2008-02-20 23:39:28 +00:00
Eric Smith bc32fee029 Added code to correct combining str and unicode in ''.format(). Added test case. 2008-02-18 18:02:34 +00:00
Eric Smith a9f7d62480 Backport of PEP 3101, Advanced String Formatting, from py3k.
Highlights:
 - Adding PyObject_Format.
 - Adding string.Format class.
 - Adding __format__ for str, unicode, int, long, float, datetime.
 - Adding builtin format.
 - Adding ''.format and u''.format.
 - str/unicode fixups for formatters.

The files in Objects/stringlib that implement PEP 3101 (stringdefs.h,
unicodedefs.h, formatter.h, string_format.h) are identical in trunk
and py3k.  Any changes from here on should be made to trunk, and
changes will propogate to py3k).

Amaury Forgeot d'Arc 632fad3933 Prevent a crash with nested scopes, again caused by calling Py_DECREF when the pointer
is still present in the containing structure.

Amaury Forgeot d'Arc 60d6c7f0cc Issue #2115: __slot__ attributes setting was 10x slower.
Also correct a possible crash using ABCs.

This change is exactly the same as an optimisation
done 5 years ago, but on slot *access*:

Eric Smith 3f91437e5f In PyNumber_ToBase, changed from an assert to returning an error when PyObject_Index() returns something other than an int or long. It should never be possible to trigger this, as PyObject_Index checks to make sure it returns an int or long. 2008-02-15 12:14:32 +00:00
Christian Heimes 2f0da53d28 Fixed repr() and str() of complex numbers. Complex suffered from the same problem as floats but I forgot to test and fix them. 2008-02-15 06:57:08 +00:00
Christian Heimes e247f0037f Use a static and interned string for __subclasscheck__ and __instancecheck__ as suggested by Thomas Heller in #2115 2008-02-14 22:40:11 +00:00

Raymond Hettinger a37430a0ce dict.copy() rises from the ashes. Revert r60687. 2008-02-12 19:05:36 +00:00
Eric Smith 5e527ebee1 Added PyNumber_ToBase and supporting routines _PyInt_Format and
_PyLong_Format.  In longobject.c, changed long_format to
_PyLong_Format.  In intobject.c, changed uses of PyOS_snprintf to
_PyInt_Format instead.

_PyLong_Format is similar to py3k's routine of the same name, except
it has 2 additional parameters: addL and newstyle.  addL was existing
in long_format, and controls adding the trailing "L".  This is
unneeded in py3k.  newstyle is used to control whether octal prepends
"0" (the pre-2.6 style), or "0o" (the 3.0 sytle).

PyNumber_ToBase is needed for PEP 3127 (Integer Literal Support and
Syntax) and PEP 3101 (Advanced String Formatting).

This changeset does not need merging into py3k.

Christian Heimes b4ee4a16f4 Added some statistics code to dict and list object code. I wanted to test how a larger freelist affects the reusage of freed objects. Contrary to my gut feelings 80 objects is more than fine for small apps. I haven't profiled a large app yet. 2008-02-07 17:15:30 +00:00
Raymond Hettinger 55285ef44c Return ints instead of longs for tuple.count() and tuple.index(). 2008-02-07 02:12:52 +00:00
Raymond Hettinger 5b07ebce86 Issue 2025: Add tuple.count() and tuple.index() to follow the ABC in collections.Sequence. 2008-02-07 00:54:20 +00:00
Christian Heimes 5b970ad483 Unified naming convention for free lists and their limits. All free lists
in Object/ are named ``free_list``, the counter ``numfree`` and the upper
limit is a macro ``PyName_MAXFREELIST`` inside an #ifndef block.

The chances should make it easier to adjust Python for platforms with
less memory, e.g. mobile phones.

Christian Heimes 6075a82243 Limit free list of method and builtin function objects to 256 entries each. 2008-02-06 12:44:34 +00:00
Christian Heimes 422051a367 Patch #1953
I implemented the function sys._compact_freelists() and C API functions PyInt_/PyFloat_CompactFreeList() to compact the pre-allocated blocks of ints and floats. They allow the user to reduce the memory usage of a Python process that deals with lots of numbers.
The patch also renames sys._cleartypecache to sys._clear_type_cache

Jeffrey Yasskin a26cf9b760 Make int() and long() fall back to __trunc__(). See issue 2002. 2008-02-04 01:04:35 +00:00
Amaury Forgeot d'Arc cab3d98ca1 Ensure that PySet_Add() operates on a newly created frozenset, like PyTuple_SetItem does.
Add PyFrozenSet_Check(), which was not needed before; The list of Py*Set_Check* macros seems to be complete now.

Add missing NEWS entries about all this.

Jeffrey Yasskin 3ea7b41b58 Moved Rational._binary_float_to_ratio() to float.as_integer_ratio() because
it's useful outside of rational numbers.

This is my first C code that had to do anything significant. Please be more
careful when looking over it.
