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

* 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.
