* Finish backporting new buffer API to Python 2.6. Left to do: memoryview ↵Travis E. Oliphant2008-03-182-3/+5
| | | | 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.

* Move abc._Abstract into object by adding a new flag Py_TPFLAGS_IS_ABSTRACT,Jeffrey Yasskin2008-02-281-0/+3
| | | | | | | | 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.

* Backport of PEP 3101, Advanced String Formatting, from py3k.Eric Smith2008-02-173-0/+31
| | | | | | | | | | | | | | | 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).

* Added PyNumber_ToBase and supporting routines _PyInt_Format andEric Smith2008-02-102-0/+13
| | | | | | | | | | | | | | | | | _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.

* Patch #1953Christian Heimes2008-02-042-0/+5
| | | | | 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

* Backport of several functions from Python 3.0 to 2.6 including ↵Christian Heimes2008-01-253-7/+33
| | | | | | | 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.
* Don't repeat yourselfChristian Heimes2008-01-221-1/+2
| | | | Added the macros PyModule_AddIntMacro and PyModule_AddStringMacro. They shorten PyModule_AddIntConstant(m, "AF_INET", AF_INET) to PyModule_AddIntMacro(m, AF_INET)

| | | | | | | 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).

* Give meaning to the oparg for BUILD_MAP: estimated size of the dictionary.Raymond Hettinger2007-12-181-0/+1
| | | | | | | | | | | 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.
* Speed-up dictionary constructor by about 10%.Raymond Hettinger2007-12-181-0/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | New opcode, STORE_MAP saves the compiler from awkward stack manipulations and specializes for dicts using PyDict_SetItem instead of PyObject_SetItem.

* Backport of r59456:59458 from py3k to trunkChristian Heimes2007-12-101-0/+4
| | | | | | 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.
* Fix Issue 1045.Raymond Hettinger2007-12-061-17/+4
| | | | | Factor-out common calling code by simplifying the length_hint API. Speed-up the function by caching the PyObject_String for the attribute lookup.
* Feature #1534Christian Heimes2007-12-011-0/+4
| | | | | 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.
* Backport of the PCbuild9 directory from the py3k branch.Christian Heimes2007-11-221-2/+2
| | | | | 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! :)
* The incremental decoder for utf-7 must preserve its state between calls.Amaury Forgeot d'Arc2007-11-201-0/+7
| | | | | | | Solves issue1460. Might not be a backport candidate: a new API function was added, and some code may rely on details in utf-7.py.
