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
Christian Heimes 3b718a79af Implemented Martin's suggestion to clear the free lists during the garbage collection of the highest generation. 2008-02-14 12:47:33 +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.

Raymond Hettinger 17a74c395e Add -3 warnings that set.copy(), dict.copy(), and defaultdict.copy() will go away in Py3.x 2008-02-09 04:37:49 +00:00

The preceding test guarantees that 0 <= i < len.

Christian Heimes f75dbef208 Deallocate content of the dict free list on interpreter shutdown 2008-02-08 00:11:31 +00:00
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.

Raymond Hettinger ecdcb58950 Make PySet_Add() work with frozensets.
Works like PyTuple_SetItem() to build-up values in a brand new frozenset.
Also, PyFrozenSet_New() is now guaranteed to produce a distinct new frozenset.

Christian Heimes d7e1b2bd17 static PyObject* variables should use PyString_InternFromString() instead of PyObject_FromString() to store a python string in a function level static var. 2008-01-28 02:07:53 +00:00
Christian Heimes 908caac52e Added clear cache methods to clear the internal type lookup cache for ref leak test runs. 2008-01-27 23:34:59 +00:00
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.

Raymond Hettinger 3dbd4c536d Changes 54857 and 54840 broke code and were reverted in Py2.5 just before
it was released, but that reversion never made it to the Py2.6 head.

Christian Heimes 7f39c9fcbb Backport of several functions from Python 3.0 to 2.6 including PyUnicode_FromString, PyUnicode_Format and PyLong_From/AsSsize_t. The functions are partly required for the backport of the bytearray type and _fileio module. They should also make it easier to port C to 3.0.
First chapter of the Python 3.0 io framework back port: _fileio
The next step depends on a working bytearray type which itself depends on a backport of the nwe buffer API.

Neal Norwitz 5f95a79b2b Add prototypes to get the mathmodule.c to compile on OSF1 5.1 (Tru64)
and eliminate a compiler warning in floatobject.c.  There might be
a better way to go about this, but it should be good enough for now.
