04c96d52a4 Issue #1996: float.as_integer_ratio() should return fraction in lowest terms. 2008-02-01 21:30:23 +00:00

4d4f270941 Patch #1970 by Antoine Pitrou: Speedup unicode whitespace and linebreak detection. The speedup is about 25% for split() (571 / 457 usec) and 35% (175 / 127 usec )for splitlines() 2008-01-30 11:32:37 +00:00

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.

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.

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.

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.

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.

c94e2b5c12 Now that I've learnt about structseq objects I felt like converting sys.float_info to a structseq. It's 
readonly and help(sys.float_info) explains the attributes nicely.

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.

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.

0b7b6fdff3 Patch #1549 by Thomas Herve. 
This changes the rules for when __hash__ is inherited slightly,
by allowing it to be inherited when one or more of __lt__, __le__,
__gt__, __ge__ are overridden, as long as __eq__ and __ne__ aren't.

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.

6c87af5d87 Optimize PyList_AsTuple(). Improve cache performance by doing the 
pointer copy and object increment in one pass.  For small lists,
save the overhead of the call to memcpy() -- this comes up in
calls like f(*listcomp).

90e10e79ea Fixed bug #1620: New @spam.getter property syntax modifies the property in place. 
I added also the feature that a @prop.getter decorator does not overwrite the doc string of the property if it was given as an argument to property().

f15c66e143 The new float repr causes too much trouble and pain. I'm disabling the feature until we have sorted out the issues on all machines. 64bit machines seem to have issues and Guido has reported even worse. 
Guido: It's pretty bad actually -- repr(1e5) comes out as '1.0'... Ditto for
repr(1eN) for most N... Both in 2.6 and in 3.0...

284d927625 Backport of r59456:59458 from py3k to trunk 
Issue #1580: New free format floating point representation based on "Floating-Point Printer Sample Code", by Robert G. Burger. For example repr(11./5) now returns '2.2' instead of '2.2000000000000002'.

Thanks to noam for the patch! I had to modify doubledigits.c slightly to support X64 and IA64 machines on Windows. I also added the new file to the three project files.
