Christian Heimes 3c60833e1e Patch #2477: Added from __future__ import unicode_literals
The new PyParser_*Ex() functions are based on Neal's suggestion and initial patch. The new __future__ feature makes all '' and r'' unicode strings. b'' and br'' stay (byte) strings.

Eric Smith 7c47894a2a Backport of the print function, using a __future__ import.
This work is substantially Anthony Baxter's, from issue
1633807.  I just freshened it, made a few minor tweaks,
and added the test cases.  I also created issue 2412,
which is to check for 2to3's behavior with the print
function.  I also added myself to ACKS.

Travis E. Oliphant 3781aef8f8 Finish backporting new buffer API to Python 2.6. Left to do: memoryview object and structmodule. But, these need to be finished in Python 3.0 first. No objects support the new buffer API in Python 2.6 as of yet, and except for the memoryview object, I don't think they will. 2008-03-18 04:44:57 +00:00

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.

Christian Heimes a3c8c10201 Thomas Herve explained to me that PyCrypto depends on the constants. I'm adding the aliases because C code for Python 2.x should compile under 2.6 as well. The aliases aren't available in Python 3.x though. 2008-02-25 17:32:07 +00:00
Christian Heimes 5224d28d38 Patch #1759: Backport of PEP 3129 class decorators
with some help from Georg
2008-02-23 15:01:05 +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).

Eric Smith dd47aaebe8 Forgot to modify header file in r60707. 2008-02-10 15:07:44 +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 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

2008-01-26 14:14:20 +00:00
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.

Guido van Rossum 02de8979cc Patch #1583 by Adam Olsen.
This adds signal.set_wakeup_fd(fd) which sets a file descriptor to
which a zero byte will be written whenever a C exception handler runs.

I added a simple C API as well, PySignal_SetWakeupFd(fd).

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.
2007-12-18 21:24:09 +00:00
Raymond Hettinger effde12f5f Speed-up dictionary constructor by about 10%.

Christian Heimes 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.

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! :)

Amaury Forgeot d'Arc 5087980c1e The incremental decoder for utf-7 must preserve its state between calls.

Brett Cannon 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.
