Ned Deily18fae3f2013-01-31 01:24:55 -08001464- Issue #13590: OS X Xcode 4 - improve support for universal extension modules
1465 In particular, fix extension module build failures when trying to use
1466 32-bit-only installer Pythons on systems with Xcode 4 (currently
1467 OS X 10.8, 10.7, and optionally 10.6).
1468 * Backport 3.3.0 fixes to 2.7 branch (for release in 2.7.4)
1469 * Since Xcode 4 removes ppc support, extension module builds now
1470 check for ppc compiler support and by default remove ppc and
1471 ppc64 archs when they are not available.
1472 * Extension module builds now revert to using system installed
1473 headers and libs (/usr and /System/Library) if the SDK used
1474 to build the interpreter is not installed or has moved.
1475 * Try to avoid building extension modules with deprecated
1476 and problematic Apple llvm-gcc compiler. If original compiler
1477 is not available, use clang instead by default.

Mark Dickinsondbbed042011-09-19 16:38:08 +01001828- Issue #12973: Fix overflow checks that invoked undefined behaviour in
1829 int.__pow__. These overflow checks were causing int.__pow__ to produce
1830 incorrect results with recent versions of Clang, as a result of the
Mark Dickinsona96b0d12011-09-24 09:01:16 +01001831 compiler optimizing the check away. Also fix similar overflow checks
1832 in list_repeat (listobject.c) and islice_next (itertoolsmodule.c). These

Florent Xiclunac2279652012-02-12 14:49:03 +01001901- Issue #13994: Earlier partial revert of Distutils enhancements in 2.7
Ned Deilyc47a4592012-02-11 20:40:24 +01001902 has left two versions of customize_compiler, the original in
1903 distutils.sysconfig and another copy in distutils.ccompiler, with some

Ned Deily0d0ea482012-02-10 12:59:06 +01001908- Issue #13590: On OS X 10.7 and 10.6 with Xcode 4.2, building
1909 Distutils-based packages with C extension modules may fail because
1910 Apple has removed gcc-4.2, the version used to build python.org
1911 64-bit/32-bit Pythons. If the user does not explicitly override
1912 the default C compiler by setting the CC environment variable,
1913 Distutils will now attempt to compile extension modules with clang
1914 if gcc-4.2 is required but not found. Also as a convenience, if
1915 the user does explicitly set CC, substitute its value as the default
1916 compiler in the Distutils LDSHARED configuration variable for OS X.
1917 (Note, the python.org 32-bit-only Pythons use gcc-4.0 and the 10.4u
1918 SDK, neither of which are available in Xcode 4. This change does not
1919 attempt to override settings to support their use with Xcode 4.)

Ned Deily87e82bb2011-06-28 19:52:59 -07002169- Issue #9516: On Mac OS X, change Distutils to no longer globally attempt to
2170 check or set the MACOSX_DEPLOYMENT_TARGET environment variable for the
2171 interpreter process. This could cause failures in non-Distutils subprocesses
2172 and was unreliable since tests or user programs could modify the interpreter
Ezio Melotti302ad8d2013-01-19 19:44:58 +02002173 environment after Distutils set it. Instead, have Distutils set the
Ned Deily87e82bb2011-06-28 19:52:59 -07002174 deployment target only in the environment of each build subprocess. It is
2175 still possible to globally override the default by setting
2176 MACOSX_DEPLOYMENT_TARGET before launching the interpreter; its value must be
2177 greater or equal to the default value, the value with which the interpreter
2178 was built.

2207 updating the check interval, so if the user decreases the check interval,
2208 the ticker doesn't have to wind down to zero from the old starting point
2209 before the new interval takes effect. And if the user increases the
2210 interval, it makes sure the new limit takes effect right away rather have an
2211 early task switch before recognizing the new interval.

3193 becoming permanently uncollectable GC garbage. The downside is that
3194 removing __del__ means that the internal doubly-linked list has to wait for
3195 GC collection rather than freeing memory immediately when the refcnt drops
3196 to zero.

Ezio Melottiab2eb0e2010-06-05 19:21:32 +00003654- Issue #8271: during the decoding of an invalid UTF-8 byte sequence, only the
3655 start byte and the continuation byte(s) are now considered invalid, instead
3656 of the number of bytes specified by the start byte.
3657 E.g.: '\xf1\x80AB'.decode('utf-8', 'replace') now returns u'\ufffdAB' and
3658 replaces with U+FFFD only the start byte ('\xf1') and the continuation byte
3659 ('\x80') even if '\xf1' is the start byte of a 4-bytes sequence.

3669 objects. (1) The comparison could incorrectly return True in some cases
3670 (2**53+1 == complex(2**53) == 2**53), breaking transivity of equality.

3813 non-float non-integer argument is now converted to an integer (if possible)
3814 using its __int__ method. Previously, only small arguments were treated this
3815 way; larger arguments (those whose __int__ was outside the range of a C long)

3867 operation raises multiple signals and more than one of those signals is
3868 trapped, the specification determines the order in which the signals should be
3869 handled. In many cases this order wasn't being followed, leading to the wrong

Georg Brandlfee0f442010-05-22 21:26:21 +00004014- Issue #8625: Turn off optimization in ``--with-pydebug`` builds with gcc.
Mark Dickinsond2f3e3f2010-05-05 22:23:58 +00004015 (Optimization was unintentionally turned on in gcc --with-pydebug builds in
4016 2.7 beta1 as a result of the issue #1628484 fix, combined with autoconf's
4017 strange choice of default CFLAGS produced by AC_PROG_CC for gcc.)

4037Core and Builtins
4038-----------------
4039
Philip Jenveyaebbaeb2010-04-06 23:24:45 +00004040- Issue #7301: Add environment variable $PYTHONWARNINGS.
4041
Benjamin Peterson3a1dfa22010-04-06 21:50:00 +00004042- Issue #8329: Don't return the same lists from select.select when no fds are
4043 changed.
4044
Georg Brandlfee0f442010-05-22 21:26:21 +00004045- Issue #8259: ``1L << (2**31)`` no longer produces an 'outrageous shift error'
Mark Dickinson82791672010-04-06 16:47:55 +00004046 on 64-bit machines. The shift count for either left or right shift is
4047 permitted to be up to sys.maxsize.
4048
Benjamin Peterson4ceeeb02010-04-03 22:48:51 +00004049- Ensure that tokenization of identifiers is not affected by locale.
4050
Georg Brandlfee0f442010-05-22 21:26:21 +00004051- Issue #1222585: Added LDCXXSHARED for C++ support. Patch by Arfrever.
Tarek Ziadé00002952010-04-03 08:37:59 +00004052
Benjamin Peterson1c7c11e2010-04-03 01:28:57 +00004053- Raise a TypeError when trying to delete a T_STRING_INPLACE struct member.
4054
Georg Brandlfee0f442010-05-22 21:26:21 +00004055- Issue #7994: Issue a PendingDeprecationWarning if object.__format__ is called
4056 with a non-empty format string. This is an effort to future-proof user
4057 code. If a derived class does not currently implement __format__ but later
4058 adds its own __format__, it would most likely break user code that had
Antoine Pitrou01a196a2011-01-02 20:05:11 +00004059 supplied a format string. This will be changed to a DeprecationWarning in
Georg Brandlfee0f442010-05-22 21:26:21 +00004060 Python 3.3 and it will be an error in Python 3.4.
Eric Smithd44b2fc2010-04-02 12:30:56 +00004061
Antoine Pitroua57df2c2010-03-31 21:32:15 +00004062- Issue #8268: Old-style classes (not just instances) now support weak

4071 arguments to a function correct.
4072
Benjamin Peterson0dee9c12010-03-17 20:41:42 +00004073- Issue #8164: Don't allow lambda functions to have a docstring.
4074
Victor Stinner66644262010-03-10 22:30:19 +00004075- Issue #3137: Don't ignore errors at startup, especially a keyboard interrupt
Georg Brandlba83f822010-03-14 09:50:54 +00004076 (SIGINT). If an error occurs while importing the site module, the error is
4077 printed and Python exits. Initialize the GIL before importing the site

4092
Georg Brandlfee0f442010-05-22 21:26:21 +00004093- Issue #8257: The Decimal construct now accepts a float instance directly,
4094 converting that float to a Decimal of equal value:
Mark Dickinson8a950712010-04-03 15:47:46 +00004095
4096 >>> Decimal(1.1)
4097 Decimal('1.100000000000000088817841970012523233890533447265625')
4098
Raymond Hettinger34c35b22010-04-03 10:22:00 +00004099- collections.Counter() now supports a subtract() method.
4100
Georg Brandlfee0f442010-05-22 21:26:21 +00004101- The functools module now has a total_ordering() class decorator to simplify
4102 the specification of rich comparisons.
Raymond Hettingera551f312010-04-04 18:34:45 +00004103
Georg Brandlfee0f442010-05-22 21:26:21 +00004104- The functools module also adds cmp_to_key() as a tool to transition old-style
4105 comparison functions to new-style key-functions.
Raymond Hettingera551f312010-04-04 18:34:45 +00004106
Georg Brandlfee0f442010-05-22 21:26:21 +00004107- Issue #8294: The Fraction constructor now accepts Decimal and float instances
4108 directly.
Mark Dickinson7c63eee2010-04-02 22:27:36 +00004109
Georg Brandlfee0f442010-05-22 21:26:21 +00004110- Issue #7279: Comparisons involving a Decimal signaling NaN now signal
4111 InvalidOperation instead of returning False. (Comparisons involving a quiet
4112 NaN are unchanged.) Also, Decimal quiet NaNs are now hashable; Decimal
4113 signaling NaNs remain unhashable.
Mark Dickinsone096e822010-04-02 10:17:07 +00004114
Georg Brandlfee0f442010-05-22 21:26:21 +00004115- Issue #2531: Comparison operations between floats and Decimal instances now
4116 return a result based on the numeric values of the operands; previously they
4117 returned an arbitrary result based on the relative ordering of id(float) and
4118 id(Decimal).
Mark Dickinson99d80962010-04-02 08:53:22 +00004119
Barry Warsawf7f2d6f2010-03-31 21:07:16 +00004120- Issue #8233: When run as a script, py_compile.py optionally takes a single
Georg Brandlfee0f442010-05-22 21:26:21 +00004121 argument `-` which tells it to read files to compile from stdin. Each line is
4122 read on demand and the named file is compiled immediately. (Original patch by
4123 Piotr Ożarowski).
Barry Warsawf7f2d6f2010-03-31 21:07:16 +00004124
Georg Brandlfee0f442010-05-22 21:26:21 +00004125- Issue #3135: Add ``inspect.getcallargs()``, which binds arguments to a

Florent Xicluna58b65662010-03-30 16:29:03 +00004128- Backwards incompatible change: Unicode codepoints line tabulation (0x0B) and
4129 form feed (0x0C) are now considered linebreaks, as specified in Unicode
Georg Brandlfee0f442010-05-22 21:26:21 +00004130 Standard Annex #14. See issue #7643. http://www.unicode.org/reports/tr14/
Florent Xicluna22b24382010-03-30 08:24:06 +00004131
Georg Brandlfee0f442010-05-22 21:26:21 +00004132- Comparisons using one of <, <=, >, >= between a complex instance and a
4133 Fractions instance now raise TypeError instead of returning True/False. This
4134 makes Fraction <=> complex comparisons consistent with int <=> complex, float
4135 <=> complex, and complex <=> complex comparisons.
Mark Dickinson9588d992010-03-27 11:14:37 +00004136

Antoine Pitrou513d9ae2010-03-22 19:59:46 +00004146- Issue #7512: shutil.copystat() could raise an OSError when the filesystem
Georg Brandlfee0f442010-05-22 21:26:21 +00004147 didn't support chflags() (for example ZFS under FreeBSD). The error is now
4148 silenced.
Antoine Pitrou513d9ae2010-03-22 19:59:46 +00004149
Florent Xicluna9e7a4c92010-03-22 16:07:38 +00004150- Issue #7703: ctypes supports both buffer() and memoryview(). The former is
4151 deprecated.

4244 the set of integer codes for which it was used differed between native packing
4245 and standard packing.)

4477 and read operations on write-only file objects. On Windows, the system C
Georg Brandlba83f822010-03-14 09:50:54 +00004478 library would return a bogus result; on Solaris, it was possible to crash the
4479 interpreter. Patch by Stefan Krah.

Georg Brandlba83f822010-03-14 09:50:54 +00004492- Issue #7766: Change ``sys.getwindowsversion()`` return value to a named tuple
4493 and add the additional members returned in an OSVERSIONINFOEX structure. The
4494 new members are service_pack_major, service_pack_minor, suite_mask, and

Georg Brandlba83f822010-03-14 09:50:54 +00004497- Issue #7561: Operations on empty bytearrays (such as ``int(bytearray())``)
4498 could crash in many places because of the ``PyByteArray_AS_STRING()`` macro
4499 returning NULL. The macro now returns a statically allocated empty string
4500 instead.

4510 strings,
4511 (2) a crash in dtoa.c that occurred in debug builds when parsing certain long
4512 numeric strings corresponding to subnormal values,
4513 (3) a memory leak for some values large enough to cause overflow, and
4514 (4) a number of flaws that could lead to incorrectly rounded results.
4515

4532 interpreter shutdown.
4533
Georg Brandlba83f822010-03-14 09:50:54 +00004534- Issue #2746: Don't escape ampersands and angle brackets ("&", "<", ">") in
4535 XML processing instructions and comments. These raw characters are allowed
4536 by the XML specification, and are necessary when outputting e.g. PHP code in
4537 a processing instruction. Patch by Neil Muller.

Antoine Pitroud840e512010-02-04 20:20:18 +00004545- Issue #4772: Raise a ValueError when an unknown Bluetooth protocol is
Georg Brandlba83f822010-03-14 09:50:54 +00004546 specified, rather than fall through to AF_PACKET (in the ``socket`` module).
Antoine Pitroud840e512010-02-04 20:20:18 +00004547 Also, raise ValueError rather than TypeError when an unknown TIPC address
4548 type is specified. Patch by Brian Curtin.

4551
Antoine Pitrouf3fa0742010-01-31 22:26:04 +00004552- Issue #6939: Fix file I/O objects in the `io` module to keep the original
Georg Brandlba83f822010-03-14 09:50:54 +00004553 file position when calling `truncate()`. It would previously change the file
4554 position to the given argument, which goes against the tradition of
Antoine Pitrouf3fa0742010-01-31 22:26:04 +00004555 ftruncate() and other truncation APIs. Patch by Pascal Chambon.
4556
Georg Brandlba83f822010-03-14 09:50:54 +00004557- Issue #7610: Reworked implementation of the internal ``zipfile.ZipExtFile``
4558 class used to represent files stored inside an archive. The new
4559 implementation is significantly faster and can be wrapped in a
4560 ``io.BufferedReader`` object for more speedups. It also solves an issue
4561 where interleaved calls to ``read()`` and ``readline()`` give wrong results.
4562 Patch by Nir Aides.
Antoine Pitrou94c33eb2010-01-27 20:59:50 +00004563
Benjamin Peterson2deb5c72010-01-27 02:16:42 +00004564- Issue #7792: Registering non-classes to ABCs raised an obscure error.

4570 when the release file is empty.
Benjamin Petersona43f34c2010-01-25 03:31:13 +00004571
Georg Brandlba83f822010-03-14 09:50:54 +00004572- Issue #7748: Since unicode values are supported for some metadata options in
4573 Distutils, the DistributionMetadata get_* methods will now return an utf-8
4574 encoded string for them. This ensures that the upload and register commands
4575 send the correct values to PyPI without any error.

4650-----------------
4651
Georg Brandlba83f822010-03-14 09:50:54 +00004652- The ``__complex__()`` method is now looked up on the class of instances to
4653 make it consistent with other special methods.

4657
Mark Dickinson1b34d252010-01-01 17:27:30 +00004658- Issue #5080: A number of functions and methods previously produced a

4660 These functions and methods now raise TypeError instead. The majority of the
4661 effects of this change are in the extension modules, but some core functions
4662 and methods are affected: notably the 'chr', 'range' and 'xrange' builtins,
4663 and many unicode/str methods.

4687
Georg Brandlba83f822010-03-14 09:50:54 +00004688 These executables now work properly with the arch(1) command: ``arch -ppc
4689 python`` will start a universal binary version of python in PPC mode (unlike

4829 to 'g' for large values.
Amaury Forgeot d'Arcd7288712009-12-01 21:51:04 +00004830
Georg Brandlba83f822010-03-14 09:50:54 +00004831- Remove switch from "%f" formatting to "%g" formatting for floats larger than
4832 1e50 in absolute value.
Mark Dickinson9dd5e162009-11-23 20:54:09 +00004833
Georg Brandlba83f822010-03-14 09:50:54 +00004834- Remove restrictions on precision when formatting floats. E.g., "%.120g" %

4836 significant digits instead.

Ronald Oussoren315cd0c2009-11-19 16:25:21 +00004844
Georg Brandlba83f822010-03-14 09:50:54 +00004845- Issue #7117: ``repr(x)`` for a float x returns a result based on the shortest
4846 decimal string that's guaranteed to round back to x under correct rounding
4847 (with round-half-to-even rounding mode). Previously it gave a string based on
4848 rounding x to 17 decimal digits. repr(x) for a complex number behaves
4849 similarly. On platforms where the correctly-rounded strtod and dtoa code is
4850 not supported (see below), repr is unchanged.
Mark Dickinsonb678de82009-11-19 18:41:49 +00004851
Georg Brandlba83f822010-03-14 09:50:54 +00004852- Issue #7117: On almost all platforms: float-to-string and string-to-float
4853 conversions within Python are now correctly rounded. Places these conversions
4854 occur include: str for floats and complex numbers; the float and complex
4855 constructors; old-style and new-style numeric formatting; serialization and
4856 deserialization of floats and complex numbers using marshal, pickle and json;
4857 parsing of float and imaginary literals in Python code; Decimal-to-float
4858 conversion.
Mark Dickinsonb678de82009-11-19 18:41:49 +00004859
Georg Brandlba83f822010-03-14 09:50:54 +00004860 The conversions use a Python-adapted version of David Gay's well-known dtoa.c,
4861 providing correctly-rounded strtod and dtoa C functions. This code is
4862 supported on Windows, and on Unix-like platforms using gcc, icc or suncc as
4863 the C compiler. There may be a small number of platforms on which correct
4864 operation of this code cannot be guaranteed, so the code is not used: notably,
4865 this applies to platforms where the C double format is not IEEE 754 binary64,
4866 and to platforms on x86 hardware where the x87 FPU is set to 64-bit precision
4867 and Python's configure script is unable to determine how to change the FPU
4868 precision. On these platforms conversions use the platform strtod and dtoa,
4869 as before.
Mark Dickinsonb678de82009-11-19 18:41:49 +00004870
Georg Brandlba83f822010-03-14 09:50:54 +00004871- Issue #7117: Backport round implementation from Python 3.x. ``round()`` now
4872 uses the correctly-rounded string <-> float conversions described above (when
4873 available), and so produces correctly rounded results that will display nicely
4874 under the float repr. There are two related small changes: (1) round now
4875 accepts any class with an ``__index__()`` method for its second argument (but
4876 no longer accepts floats for the second argument), and (2) an excessively
4877 large second integer argument (e.g., ``round(1.234, 10**100)``) no longer
4878 raises an exception.

Georg Brandlba83f822010-03-14 09:50:54 +00005025- Issue #5920: For ``float.__format__()``, change the behavior with the empty
5026 presentation type (that is, not one of 'e', 'f', 'g', or 'n') to be like 'g'
5027 but with at least one decimal point and with a default precision
5028 of 12. Previously, the behavior the same but with a default precision of 6.
5029 This more closely matches ``str()``, and reduces surprises when adding
5030 alignment flags to the empty presentation type. This also affects the new
5031 complex.__format__ in the same way.

Georg Brandl6425a2f2008-12-28 11:54:53 +00005194- Issue #4759: None is now allowed as the first argument of
Georg Brandlba83f822010-03-14 09:50:54 +00005195 ``bytearray.translate()``. It was always allowed for ``bytes.translate()``.
Georg Brandl6425a2f2008-12-28 11:54:53 +00005196
Skip Montanarof205c132008-12-23 03:30:15 +00005197- Added test case to ensure attempts to read from a file opened for writing
5198 fail.
5199
Georg Brandlba83f822010-03-14 09:50:54 +00005200- Issue #2467: gc.DEBUG_STATS reported invalid elapsed times. Also, always print

Georg Brandlba83f822010-03-14 09:50:54 +00005214- Issue #4445: Replace ``sizeof(PyStringObject)`` with
5215 ``offsetof(PyStringObject, ob_sval) + 1`` when allocating memory for str
5216 instances. On a typical machine this saves 3 bytes of memory (on average) per
5217 string allocation.

Amaury Forgeot d'Arcdc619012008-11-22 20:01:18 +00005219- Issue #3996: On Windows, the PyOS_CheckStack function would cause the
5220 interpreter to abort ("Fatal Python error: Could not reset the stack!")
5221 instead of throwing a MemoryError.
5222
Georg Brandlba83f822010-03-14 09:50:54 +00005223- Issue #3689: The list reversed iterator now supports __length_hint__ instead

Benjamin Petersonc078f922008-11-21 22:27:24 +00005226- Issue #4367: Python would segfault during compiling when the unicodedata

5228
Georg Brandlba83f822010-03-14 09:50:54 +00005229- Issue #4233: Changed semantic of ``_fileio.FileIO``'s ``close()`` method on
5230 file objects with closefd=False. The file descriptor is still kept open but
5231 the file object behaves like a closed file. The ``FileIO`` object also got a
5232 new readonly attribute ``closefd``.

Benjamin Peterson46cc6d12008-11-19 21:49:09 +00005234- Issue #4348: Some bytearray methods returned that didn't cause any change to
5235 the bytearray, returned the same bytearray instead of a copy.
5236
Georg Brandlba83f822010-03-14 09:50:54 +00005237- Issue #4317: Fixed a crash in the ``imageop.rgb2rgb8()`` function.

Benjamin Petersonbdca9422008-10-26 20:21:13 +00005249- Issue #4209: Enabling unicode_literals and the print_function in the same
5250 __future__ import didn't work.
5251
Benjamin Peterson399b1fe2008-10-25 02:53:28 +00005252- Using ``nonlocal`` as a variable name will now raise a Py3k SyntaxWarning
Georg Brandl7fb00ad2008-10-25 07:00:52 +00005253 because it is a reserved word in 3.x.
Benjamin Peterson399b1fe2008-10-25 02:53:28 +00005254
Georg Brandlba83f822010-03-14 09:50:54 +00005255- On windows, ``os.chdir()`` given unicode was not working if
5256 GetCurrentDirectoryW returned a path longer than MAX_PATH. (But It's doubtful
5257 this code path is really executed because I cannot move to such directory on
5258 win2k)
Hirokazu Yamamoto10a018c2008-10-09 10:00:30 +00005259
Georg Brandlba83f822010-03-14 09:50:54 +00005260- Issue #4069: When ``set.remove(element)`` is used with a set element, the
5261 element is temporarily replaced with an equivalent frozenset. But the
5262 eventual KeyError would always report the empty ``frozenset()`` as the missing
5263 key. Now it correctly refers to the initial element.

Gregory P. Smith2b3eb372009-04-05 23:48:26 +00005280- Issue #5705: os.setuid() would not accept values > 2**31-1 but pwd.getpwnam()
5281 returned them on 64bit platforms.
5282
Walter Dörwalded960ac2009-05-03 22:36:33 +00005283- Issue #5108: Handle %s like %S and %R in PyUnicode_FromFormatV(): Call
5284 PyUnicode_DecodeUTF8() once, remember the result and output it in a second
5285 step. This avoids problems with counting UTF-8 bytes that ignores the effect
5286 of using the replace error handler in PyUnicode_DecodeUTF8().
5287
Walter Dörwald726ba8e2009-05-06 14:32:35 +00005288- Issue #3739: The unicode-internal encoder now reports the number of characters
5289 consumed like any other encoder (instead of the number of bytes).
5290
Georg Brandlba83f822010-03-14 09:50:54 +00005291- Issue #2422: When compiled with the ``--with-valgrind`` option, the pymalloc
5292 allocator will be automatically disabled when running under Valgrind. This
5293 gives improved memory leak detection when running under Valgrind, while taking
5294 advantage of pymalloc at other times.

6087 rather than 0). This is consistent with the behaviour of the traditional 2.x

Guilherme Polo7f146ab2009-06-21 17:22:50 +00006539- Issue #5450: Moved tests involving loading tk from Lib/test/test_tcl to
6540 Lib/lib-tk/test/test_tkinter/test_loadtk. With this, these tests demonstrate
Georg Brandlba83f822010-03-14 09:50:54 +00006541 the same behaviour as test_ttkguionly (and now also test_tk) which is to skip
6542 the tests if DISPLAY is defined but can't be used.

Georg Brandlba83f822010-03-14 09:50:54 +00006547- Issue #5354: New test support function import_fresh_module() makes it easy to
6548 import both normal and optimised versions of modules. test_heapq and
6549 test_warnings have been adjusted to use it, tests for other modules with both
6550 C and Python implementations in the stdlib can be adjusted to use it over
6551 time.

6560 should cause a test to be skipped are now done using import_module from test
6561 support, which does the conversion.

6663
Amaury Forgeot d'Arc05e34492008-09-10 22:04:45 +00006664- Issue #3743: In a few places, PY_FORMAT_SIZE_T was incorrectly used with
6665 PyString_FromFormat or PyErr_Format to display size_t values. The macro
6666 PY_FORMAT_SIZE_T is designed to select the correct format for the OS
6667 ``printf`` function, whereas PyString_FromFormat has an independent
6668 implementation and uses "%zd" on all platforms for size_t values.
6669 This makes a difference on win64, where ``printf`` needs "%Id" to display
6670 64bit values.

6676 object; previously an int would be returned for small values. the __long__
6677 method is allowed to return either an int or a long, but the behaviour of

Antoine Pitroud4ae97b2008-08-29 18:39:48 +00006687 was correctly parsed but parsing of subsequent arguments failed.
6688
Vinay Sajip35e3b032008-09-01 14:33:59 +00006689- Issue #2534: speed up isinstance() and issubclass() by 50-70%, so as to
Antoine Pitrou0668c622008-08-26 22:42:08 +00006690 match Python 2.5 speed despite the __instancecheck__ / __subclasscheck__
6691 mechanism. In the process, fix a bug where isinstance() and issubclass(),

6693 __instancecheck__ / __subclasscheck__ on the tuple rather than on each
6694 type object.

Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00006833What's New in Python 2.6 beta 3?
6834================================
6835
Barry Warsaw07a4a382008-08-21 01:15:08 +00006836*Release date: 20-Aug-2008*
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00006837
6838Core and Builtins
6839-----------------
6840
Guido van Rossumf8402962008-08-20 15:01:50 +00006841- Issue #1878: Remove Py_TPFLAGS_HAVE_VERSION_TAG from
6842 Py_TPFLAGS_DEFAULT when not building the core. This means 3rd party
6843 extensions do not automatically benefit from the class attribute
6844 cache; they will have to explicitly add Py_TPFLAGS_HAVE_VERSION_TAG
6845 to their tp_flags field if they care. This is a backwards
6846 compatibility feature; in 3.0, all types will use the cache by
6847 default.
6848
Benjamin Petersonf647dc12008-08-20 01:27:30 +00006849- Keyword arguments can now follow starred arguments. (``f(a, *args,
6850 keyword=23)`` is now valid syntax.)
6851
Thomas Heller0ad5ae02008-08-19 19:25:04 +00006852- ctypes function pointers that are COM methods have a boolean True
6853 value again.
6854
Martin v. Löwisf91d46a2008-08-12 14:49:50 +00006855- Issue #3139: Make buffer-interface thread-safe wrt. PyArg_ParseTuple,
6856 by denying s# to parse objects that have a releasebuffer procedure,
6857 and introducing s*.
6858
Georg Brandl1e13ea92008-08-11 09:07:59 +00006859- Issue #3537: Fix an assertion failure when an empty but presized dict
6860 object was stored in the freelist.
6861
Mark Dickinsonb6467572008-08-04 21:30:09 +00006862- Issue #1481296: Make long(float('nan')) and int(float('nan')) raise
6863 ValueError consistently across platforms.
6864
Amaury Forgeot d'Arc39fd6722008-07-31 21:28:03 +00006865- Issue #3479: On platforms where sizeof(int) is smaller than sizeof(long)
6866 (64bit Unix, for example), unichr() would truncate its argument and return
6867 u'\x00' for unichr(2**32). Now it properly raises an OverflowError.
6868
Neal Norwitze7d8be82008-07-31 17:17:14 +00006869- Apply security patches from Apple.
6870
Amaury Forgeot d'Arc246daed2008-07-31 00:42:16 +00006871- Issue #2542: Now that issubclass() may call arbitrary code, ensure that
6872 PyErr_ExceptionMatches returns 0 when an exception occurs there.
6873
Antoine Pitrou92f82162008-07-25 22:22:08 +00006874- Issue #1819: function calls with several named parameters are now on
6875 average 35% faster (as measured by pybench).
6876
Amaury Forgeot d'Arce4921fe2008-07-21 22:00:38 +00006877- Issue #2378: An unexpected UnboundLocalError or NameError could appear when
6878 the python debugger steps into a class statement: the free variables (local
6879 variables defined in an outer scope) would be deleted from the outer scope.
6880
Gregory P. Smith0470bab2008-07-22 04:46:32 +00006881- Issue #2620: Overflow checking when allocating or reallocating memory
6882 was not always being done properly in some python types and extension
6883 modules. PyMem_MALLOC, PyMem_REALLOC, PyMem_NEW and PyMem_RESIZE have
6884 all been updated to perform better checks and places in the code that
6885 would previously leak memory on the error path when such an allocation
6886 failed have been fixed.
6887
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00006888Library
6889-------
6890
Hirokazu Yamamoto838c79f2008-08-20 13:14:07 +00006891- Issue #3612: Added some missing basic types in ctypes.wintypes.
6892
Benjamin Petersone977ad42008-08-20 01:42:01 +00006893- The methods ``is_in_tuple()``, ``is_vararg()``, and ``is_keywordarg()`` of
6894 symtable.Symbol have been deprecated for removal in 3.0 and the next release.
6895
Amaury Forgeot d'Arc351ffb82008-08-18 19:23:47 +00006896- Issue #2234: distutils failed for some versions of the cygwin compiler. The
6897 version reported by these tools does not necessarily follow the python
6898 version numbering scheme, so the module is less strict when parsing it.
6899
Nick Coghlanf70385a2008-08-18 12:42:46 +00006900- Issue #2235: Added Py3k warnings for types which will become unhashable
6901 under the stricter __hash__ inheritance rules in 3.0. Several types
6902 which did not meet the rules for hash invariants and were already
6903 unhashable in 3.0 have now been explicitly flagged as unhashable in
6904 2.6 as well (collections.Mapping, collections.Set, unittest.TestSuite,
6905 xml.dom.minidom.NamedNodeMap, numbers.Number, UserList.UserList)
6906
Brett Cannon88f801d2008-08-18 00:46:22 +00006907- Update __all__ for cookielib, csv, os, urllib2, and weakref to include things
6908 imported into the module but exposed as part of the module's API.
6909
Brett Cannon7b96f072008-08-18 00:41:11 +00006910- Remove an unneeded import of abc.ABCMeta from 'inspect'.
6911
Brett Cannon46225e72008-08-18 00:36:52 +00006912- Remove unneeded imports of 'sys' and 'warnings' from 'io'.
6913
Brett Cannon25c9d6a2008-08-17 22:10:11 +00006914- Remove unneeded imports of 'warnings' from shelve, filecmp, and dummy_thread.
6915
Hirokazu Yamamoto41a81eb2008-08-17 13:10:46 +00006916- Issue #3575: Incremental decoder's decode function now takes bytearray
6917 by using 's*' instead of 't#'.
6918
Mark Dickinson3e4caeb2009-02-21 20:27:01 +00006919- Issue #2222: Fixed reference leak when occurred os.rename()
Hirokazu Yamamoto7f30a682008-08-17 09:46:56 +00006920 fails unicode conversion on 2nd parameter. (windows only)
6921
Georg Brandl222e2082010-08-01 22:27:39 +00006922- Issue #2464: urllib2 now supports a malformation in the URL received
Facundo Batista94f243a2008-08-17 03:38:39 +00006923 in a redirect.
6924
Brett Cannonabe423e2008-08-16 21:47:07 +00006925- Silence the DeprecationWarning raised when importing mimetools in
Brett Cannon721b1452008-08-16 22:00:27 +00006926 BaseHTTPServer, cgi (and rfc822), httplib.
Brett Cannonabe423e2008-08-16 21:47:07 +00006927
Facundo Batistaeb90b782008-08-16 14:44:07 +00006928- Issue #2776: fixed small issue when handling an URL with double slash
6929 after a 302 response in the case of not going through a proxy.
6930
Antoine Pitroub90a8be2008-08-15 21:03:21 +00006931- Issue #2676: in the email package, content-type parsing was hanging on
6932 pathological input because of quadratic or exponential behaviour of a
6933 regular expression.
6934
Antoine Pitrou11ec65d2008-08-14 21:04:30 +00006935- Issue #3476: binary buffered reading through the new "io" library is now
6936 thread-safe.
6937
Brett Cannonbf3157b2008-08-14 05:00:03 +00006938- Silence the DeprecationWarning of rfc822 when it is imported by mimetools
6939 since mimetools itself is deprecated. Because modules are cached, all
6940 subsequent imports of rfc822 will not raise a visible DeprecationWarning.
6941
Antoine Pitrou9fcd4b32008-08-11 17:21:36 +00006942- Issue #3134: shutil referenced undefined WindowsError symbol.
6943
Robert Schuppenies14646332008-08-10 11:01:53 +00006944- Issue #1342811: Fix leak in Tkinter.Menu.delete. Commands associated to
6945 menu entries were not deleted.
6946
Brett Cannon83e81842008-08-09 23:30:55 +00006947- Copied the implementation of reduce() to _functools.reduce() to have a
6948 version that did not raise a DeprecationWarning under -3.
6949
Antoine Pitrou76b8bee2008-08-09 17:27:23 +00006950- Issue #3205: When iterating over a BZ2File fails allocating memory, raise
6951 a MemoryError rather than silently stop the iteration.
6952
Guido van Rossum59ce9012008-08-09 14:55:34 +00006953- Issue #3487: sre "bytecode" validator. Passing invalid "re-bytecode"
6954 to _sre.compile() will now be rejected. This should not affect anybody
6955 since the re.compile() function never generates invalid re-bytecode.
6956
Skip Montanaroa032bf42008-08-08 22:52:51 +00006957- Issue #3436: Make csv.DictReader's fieldnames attribute a property so that
6958 upon first access it can be automatically initialized from the csv file if
6959 it wasn't initialized during instantiation.
6960
Brett Cannon3aa2a492008-08-06 22:28:09 +00006961- Issue #2338: Create imp.reload() to help with transitioning to Python 3.0 as
6962 the reload() built-in has been removed.
6963
Brett Cannon7e30b672008-08-04 21:52:25 +00006964- Changed code in the following modules/packages to remove warnings raised
Brett Cannonc1b76e42008-08-09 23:06:16 +00006965 while running under the ``-3`` flag: aifc, asynchat, asyncore, bdb, bsddb,
Brett Cannon047e4a92008-08-17 04:16:04 +00006966 ConfigParser, cookielib, csv, difflib, distutils, DocXMLRPCServer, email,
6967 filecmp, fileinput, inspect, logging, modulefinder, pdb, pickle, profile,
6968 pstats, pydoc, re, rlcompleter, SimpleXMLRPCServer, shelve, socket,
6969 subprocess, sqlite3, tarfile, Tkinter, test.test_support, textwrap,
6970 threading, tokenize, traceback, urlparse, wsgiref, xml, xmlrpclib.
Brett Cannon7e30b672008-08-04 21:52:25 +00006971
Lars Gustäbel727bd0b2008-08-02 11:26:39 +00006972- Issue #3039: Fix tarfile.TarFileCompat.writestr() which always
6973 raised an AttributeError.
6974
Benjamin Peterson01a24322008-07-28 23:35:27 +00006975- Issue #2523: Fix quadratic behaviour when read()ing a binary file without
Antoine Pitroude781a42008-08-09 12:43:23 +00006976 asking for a specific length. This problem only affected files opened
6977 using the new "io" module, not the built-in open() function.
Benjamin Peterson01a24322008-07-28 23:35:27 +00006978
Mark Dickinsonfe84cce2008-07-27 06:39:07 +00006979- Issue #3449: Update decimal module to use most recent specification
6980 (v. 1.68) and tests (v. 2.58) from IBM.
6981
Georg Brandl222e2082010-08-01 22:27:39 +00006982- Issue #3437: Bug fix in robotparser parsing of Allow: lines.
Skip Montanarof9ac43f2008-07-27 00:50:41 +00006983
Georg Brandl222e2082010-08-01 22:27:39 +00006984- Issue #1592: Improve error reporting when operations are attempted
Raymond Hettinger8c664e82008-07-25 18:43:33 +00006985 on a closed shelf.
6986
Georg Brandlf9efabb2008-07-23 15:16:45 +00006987- Deprecate the "ast" parser function aliases.
6988
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00006989- Issue #3120: On 64-bit Windows the subprocess module was truncating handles.
6990
6991- Issue #3303: Fix a crash in locale.strcoll() when calling it with
6992 invalid arguments.
6993
6994- Issue #3302: Fix several crashes when calling locale's gettext functions
6995 with None arguments.
6996
6997- Issue #3389: Allow resolving dotted names for handlers in logging
6998 configuration files.
6999
7000- Deprecate the sunaudio module for removal in Python 3.0.
7001
Antoine Pitrou5fdfa3e2008-07-25 19:42:26 +00007002- Issue #3394: zipfile.writestr sets external attributes when passed a
7003 file name rather than a ZipInfo instance, so files are extracted with
7004 mode 0600 rather than 000 under Unix.
7005
Gregory P. Smitha36f8fe2008-08-04 00:13:29 +00007006- Issue #1857: subprocess.Popen.poll gained an additional _deadstate keyword
7007 argument in python 2.5, this broke code that subclassed Popen to include its
7008 own poll method. Fixed my moving _deadstate to an _internal_poll method.

7016-------------
7017
Nick Coghlan6e8fef02008-08-18 13:14:22 +00007018- Issue #2235: the C API function PyObject_HashNotImplemented and its
7019 interaction with the tp_hash slot (added in 2.6b2) are now documented
7020
Nick Coghlan2a0c2b12008-08-04 12:47:17 +00007021- Issue #643841: The language reference now provides more detailed
7022 coverage of the lookup process for special methods. The disclaimers
7023 regarding lack of coverage of new-style classes have also been
7024 removed, since the coverage is now fairly reasonable.

Raymond Hettingere3ae6552008-06-20 04:18:15 +00007027What's New in Python 2.6 beta 2?
7028================================
7029
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00007030*Release date: 17-Jul-2008*
7031
Raymond Hettingere3ae6552008-06-20 04:18:15 +00007032Core and Builtins
7033-----------------
7034
Georg Brandl3e483f62008-07-16 22:57:41 +00007035- Issue #3156: Fix inconsistent behavior of the bytearray type: all
7036 its methods now allow for items objects that can be converted to
7037 an integer using operator.index().
7038
Mark Dickinson64b7e502008-07-16 09:40:03 +00007039- Issue #3360: Fix incorrect parsing of '020000000000.0', which
7040 produced a ValueError instead of giving the correct float.
7041
Eric Smitha5fa5a22008-07-16 00:11:49 +00007042- Issue #3083: Add alternate (#) formatting for bin, oct, hex output
7043 for str.format(). This adds the prefix 0b, 0o, or 0x, respectively.
7044
Mark Dickinson7103aa42008-07-15 19:08:33 +00007045- Issue #3008: the float type has a new instance method 'float.hex'
7046 and a new class method 'float.fromhex' to convert floating-point
7047 numbers to and from hexadecimal strings, respectively.
7048
Nick Coghlan6d6bd442008-07-15 15:40:22 +00007049- Issue #2235: __hash__ is once again inherited by default. To allow
7050 collections.Hashable to remain meaningful in the presence of the
7051 default hash implementation (object.__hash__), it is now possible
7052 to explicit block inheritance of hash by setting __hash__=None at
7053 the Python level, or tp_hash=PyObject_HashNotImplemented at the C
7054 level.
7055
Nick Coghlanb028f502008-07-13 14:52:36 +00007056- Issue #3221: Issue a RuntimeWarning instead of raising SystemError if
7057 the parent module cannot be found while performing an absolute import.
7058 This means that an incorrectly defined __package__ attribute will
7059 now only prevent relative imports in that module rather than causing
7060 all imports from that module to fail.
7061
Nick Coghlan14ff9942008-07-08 14:21:42 +00007062- Issue #2517: Allow unicode messages in Exceptions again by correctly
7063 bypassing the instance dictionary when looking up __unicode__ on
7064 new-style classes.
7065
Amaury Forgeot d'Arcbdd941f2008-07-01 20:38:04 +00007066- Issue #3242: Fix a crash inside the print statement, if sys.stdout is
7067 set to a custom object whose write() method happens to install
7068 another file in sys.stdout.
7069
Amaury Forgeot d'Arc1f40c8a2008-06-30 22:42:40 +00007070- Issue #3088: Corrected a race condition in classes derived from
7071 threading.local: the first member set by a thread could be saved in
7072 another thread's dictionary.
7073
Mark Dickinson1ec2fcd2008-06-20 14:53:43 +00007074- Issue #3004: Minor change to slice.indices(): the start and stop
7075 arguments are now treated identically, making the behaviour easier
7076 to describe and understand. For example, slice(None, -10,
7077 1).indices(9) now returns (0, 0, 1) instead of (0, -1, 1), and
7078 slice(None, 10, -1).indices(10) returns (9, 9, -1) instead of (9,
7079 10, -1).
7080
Georg Brandl278fc502008-07-19 12:46:12 +00007081- Issue #3219: Calling a function with repeated keyword arguments,
7082 f(a=2, a=23), would not cause a syntax error. This was a regression
7083 from 2.4 caused by the switch to the new compiler.
Benjamin Peterson175e4d92008-07-01 19:34:52 +00007084
Georg Brandl278fc502008-07-19 12:46:12 +00007085- Issue #2862: Make int and float freelist management consistent with
7086 other freelists. Changes their CompactFreeList apis into
7087 ClearFreeList apis and calls them via gc.collect().

Thomas Heller57adf222008-08-14 19:10:48 +00007092- Issue #3554: ctypes.string_at and ctypes.wstring_at did call Python
7093 api functions without holding the GIL, which could lead to a fatal
7094 error when they failed.
7095
Martin v. Löwisaabf4042008-08-02 07:20:25 +00007096- Issue #799428: Fix Tkinter.Misc._nametowidget to unwrap Tcl command objects.

Thomas Heller2bad6572008-07-15 17:19:50 +00007112- Issue #3258: Fixed a crash when a ctypes POINTER type to an
7113 incomplete structure was created.

7528
Ronald Oussoren5640ce22008-06-05 12:58:24 +00007529- On MacOS X it is now possible to install the framework in 64-bit
7530 mode or even as a 4-way universal binary (that is, PPC, i386,
Georg Brandl5cc774e2008-06-11 20:28:06 +00007531 PPC64 and x86_64 support in one binary).
Ronald Oussoren5640ce22008-06-05 12:58:24 +00007532
7533 This is controlled by the configure argument ``--with-universal-archs``:
7534
7535 - ``--with-universal-archs=all``: install 4-way universal
7536
7537 - ``--with-universal-archs=32-bit``: install 2-way universal, 32-bit (the default)
7538
7539 - ``--with-universal-archs=64-bit``: install 2-way universal, 64-bit
7540
7541 This option should be used in combination with ``--enable-universalsdk=``.
7542
7543 NOTE: 64-bit and 4-way builds are only suppported on Mac OS X 10.5 (or later).

7579 two handlers that derive the same default base class.
Amaury Forgeot d'Arc96865852008-04-22 21:14:41 +00007580
Christian Heimese74c8f22008-04-19 02:23:57 +00007581- Added kill, terminate and send_signal(sig) to subprocess.Popen.
7582
Georg Brandl3ee81df2008-05-17 18:14:43 +00007583- Added phase(z) -> phi, polar(z) -> r, phi and rect(r, phi) -> z to
7584 the cmath module.
Christian Heimes6f341092008-04-18 23:13:07 +00007585

7590 when passed a value less than or equal to zero.
Gregory P. Smith671c5d92008-04-09 18:18:43 +00007591
Georg Brandl3ee81df2008-05-17 18:14:43 +00007592- Issue #1631171: Re-implement the 'warnings' module in C (the
7593 original Python code has been kept as backup). This will allow for
7594 using the 'warning's machinery in such places as the parser where
7595 use of pure Python code is not possible. Both the ``showarning()``
7596 and ``formatwarning()`` gain an optional 'line' argument which is
7597 not called by default for backwards-compatibility reasons. Setting
7598 ``warnings.showwarning()`` to an implementation that lacks support
7599 for the ``line`` argument will raise a DeprecationWarning.

7623
Gregory P. Smithd59fefb2008-04-22 08:11:33 +00007624- The getpass module has been improved on Unix. It now uses /dev/tty
7625 by default and uses stderr instead of stdout. A GetPassWarning is
7626 issued when input echo cannot be controlled.
Gregory P. Smith41e30182008-04-21 21:31:08 +00007627

Georg Brandl3ee81df2008-05-17 18:14:43 +00007641- Issue #2513: distutils on Windows is now capable of cross-compiling
Mark Hammond495cf992008-04-07 01:53:39 +00007642 extension modules between 32 and 64 bit platforms. See the distutls

Georg Brandl3ee81df2008-05-17 18:14:43 +00007662- Issue #2550: The approach used by client/server code for obtaining
7663 ports to listen on in network-oriented tests has been refined in an
7664 effort to facilitate running multiple instances of the entire
7665 regression test suite in parallel without issue.
7666 test_support.bind_port() has been fixed such that it will always
7667 return a unique port -- which wasn't always the case with the
7668 previous implementation, especially if socket options had been set
7669 that affected address reuse (i.e. SO_REUSEADDR, SO_REUSEPORT). The
7670 new implementation of bind_port() will actually raise an exception
7671 if it is passed an AF_INET/SOCK_STREAM socket with either the
7672 SO_REUSEADDR or SO_REUSEPORT socket option set. Furthermore, if
7673 available, bind_port() will set the SO_EXCLUSIVEADDRUSE option on
7674 the socket it's been passed. This currently only applies to
7675 Windows. This option prevents any other sockets from binding to the
7676 host/port we've bound to, thus removing the possibility of the
7677 'non-deterministic' behaviour, as Microsoft puts it, that occurs
7678 when a second SOCK_STREAM socket binds and accepts to a host/port
7679 that's already been bound by another socket. The optional preferred
7680 port parameter to bind_port() has been removed. Under no
7681 circumstances should tests be hard coding ports!
7682
7683 test_support.find_unused_port() has also been introduced, which will
7684 pass a temporary socket object to bind_port() in order to obtain an
7685 unused port. The temporary socket object is then closed and
7686 deleted, and the port is returned. This method should only be used
7687 for obtaining an unused port in order to pass to an external program
7688 (i.e. the -accept [port] argument to openssl's s_server mode) or as
7689 a parameter to a server-oriented class that doesn't give you direct
7690 access to the underlying socket used.
7691
7692 Finally, test_support.HOST has been introduced, which should be used
7693 for the host argument of any relevant socket calls (i.e. bind and
7694 connect).

7696 The following tests were updated to following the new conventions:
Georg Brandl3ee81df2008-05-17 18:14:43 +00007697 test_socket, test_smtplib, test_asyncore, test_ssl, test_httplib,
Trent Nelsone41b0062008-04-08 23:47:30 +00007698 test_poplib, test_ftplib, test_telnetlib, test_socketserver,
7699 test_asynchat and test_socket_ssl.
7700
Georg Brandl3ee81df2008-05-17 18:14:43 +00007701 It is now possible for multiple instances of the regression test
7702 suite to run in parallel without issue.

7970
Fred Drakea8ee94b2008-03-01 02:45:07 +00007971- Issue #2051: pyc and pyo files are no longer created with permission
Barry Warsaw52973612008-03-01 02:23:38 +00007972 644. The mode is now inherited from the py file.
Christian Heimes40346852008-02-23 17:52:07 +00007973
Georg Brandlad61bc82008-02-23 15:11:18 +00007974- Issue #2067: file.__exit__() now calls subclasses' close() method.
7975
7976- Patch #1759: Backport of PEP 3129 class decorators.
Christian Heimes5224d282008-02-23 15:01:05 +00007977
Vinay Sajipb7edfc42008-04-02 21:10:23 +00007978- Issue #1881: An internal parser limit has been increased. Also see
Georg Brandl222e2082010-08-01 22:27:39 +00007979 issue #215555 for a discussion.
Facundo Batistafc2d0102008-02-23 12:01:13 +00007980
Eric Smitha73fbe72008-02-23 03:09:44 +00007981- Added the future_builtins module, which contains hex() and oct().
7982 These are the PEP 3127 version of these functions, designed to be
7983 compatible with the hex() and oct() builtins from Python 3.0. They
7984 differ slightly in their output formats from the existing, unchanged
7985 Python 2.6 builtins. The expected usage of the future_builtins
7986 module is:
7987 from future_builtins import hex, oct
7988
Eric Smith7ef40bf2008-02-20 23:34:22 +00007989- Issue #1600: Modifed PyOS_ascii_formatd to use at most 2 digit
7990 exponents for exponents with absolute value < 100. Follows C99
7991 standard. This is a change on Windows, which would use 3 digits.
7992 Also, added 'n' to the formats that PyOS_ascii_formatd understands,
7993 so that any alterations it does to the resulting string will be
7994 available in stringlib/formatter.h (for float.__format__).
7995
Eric Smith5a3c1352008-02-19 13:21:56 +00007996- Implemented PEP 3101, Advanced String Formatting. This adds a new
7997 builtin format(); a format() method for str and unicode; a
7998 __format__() method to object, str, unicode, int, long, float, and
7999 datetime; the class string.Formatter; and the C API
8000 PyObject_Format().
8001
Georg Brandl3ee81df2008-05-17 18:14:43 +00008002- Fixed several potential crashes, all caused by specially crafted
8003 __del__ methods exploiting objects in temporarily inconsistent
8004 state.
Amaury Forgeot d'Arc632fad32008-02-16 20:55:24 +00008005
Vinay Sajipb7edfc42008-04-02 21:10:23 +00008006- Issue #2115: Important speedup in setting __slot__ attributes. Also
Georg Brandl3ee81df2008-05-17 18:14:43 +00008007 prevent a possible crash: an Abstract Base Class would try to access
8008 a slot on a registered virtual subclass.
Amaury Forgeot d'Arc60d6c7f2008-02-15 21:22:45 +00008009
Georg Brandl3ee81df2008-05-17 18:14:43 +00008010- Fixed repr() and str() of complex numbers with infinity or nan as
8011 real or imaginary part.
Christian Heimes2f0da532008-02-15 06:57:08 +00008012
Georg Brandl3ee81df2008-05-17 18:14:43 +00008013- Clear all free lists during a gc.collect() of the highest generation
8014 in order to allow pymalloc to free more arenas. Python may give back
8015 memory to the OS earlier.
Christian Heimes3b718a72008-02-14 12:47:33 +00008016
Georg Brandl3ee81df2008-05-17 18:14:43 +00008017- Issue #2045: Fix an infinite recursion triggered when printing a
8018 subclass of collections.defaultdict, if its default_factory is set
8019 to a bound method.
Amaury Forgeot d'Arcb01aa432008-02-08 00:56:02 +00008020
Christian Heimesf75dbef2008-02-08 00:11:31 +00008021- Fixed a minor memory leak in dictobject.c. The content of the free
8022 list was not freed on interpreter shutdown.
8023
Georg Brandl21e99f42010-03-07 15:23:59 +00008024- Limit free list of method and built-in function objects to 256
Georg Brandl3ee81df2008-05-17 18:14:43 +00008025 entries each.
Christian Heimes6075a822008-02-06 12:44:34 +00008026
Georg Brandl3ee81df2008-05-17 18:14:43 +00008027- Patch #1953: Added ``sys._compact_freelists()`` and the C API
8028 functions ``PyInt_CompactFreeList`` and ``PyFloat_CompactFreeList``
Christian Heimes422051a2008-02-04 18:00:12 +00008029 to compact the internal free lists of pre-allocted ints and floats.
8030
Georg Brandl3ee81df2008-05-17 18:14:43 +00008031- Issue #1983: Fixed return type of fork(), fork1() and forkpty()
8032 calls. Python expected the return type int but the fork familie
8033 returns pi_t.
Christian Heimes951cc0f2008-01-31 23:08:23 +00008034
Georg Brandl3ee81df2008-05-17 18:14:43 +00008035- Issue #1678380: Fix a bug that identifies 0j and -0j when they
8036 appear in the same code unit.
Mark Dickinson105be772008-01-31 22:17:37 +00008037
Georg Brandl3ee81df2008-05-17 18:14:43 +00008038- Issue #2025: Add tuple.count() and tuple.index() methods to comply
8039 with the collections.Sequence API.
Raymond Hettinger5b07ebc2008-02-07 00:54:20 +00008040
Georg Brandl3ee81df2008-05-17 18:14:43 +00008041- Patch #1970 by Antoine Pitrou: Speedup unicode whitespace and
8042 linebreak detection
Christian Heimes4d4f2702008-01-30 11:32:37 +00008043
Georg Brandl3ee81df2008-05-17 18:14:43 +00008044- Added ``PyType_ClearCache()`` and ``sys._clear_type_cache`` to clear
8045 the internal lookup cache for ref leak tests.
Christian Heimes908caac2008-01-27 23:34:59 +00008046
Georg Brandl3ee81df2008-05-17 18:14:43 +00008047- Patch #1473257: generator objects gain a gi_code attribute. This is
8048 the same object as the func_code attribute of the function that
8049 produced the generator.
Georg Brandl0cdf9a32008-01-26 14:14:20 +00008050
Georg Brandl3ee81df2008-05-17 18:14:43 +00008051- Issue #1920: "while 0" statements were completely removed by the
8052 compiler, even in the presence of an "else" clause, which is
8053 supposed to be run when the condition is false. Now the compiler
8054 correctly emits bytecode for the "else" suite.
Amaury Forgeot d'Arc31eaafe2008-01-24 22:59:25 +00008055
Guido van Rossumeead05f2008-01-24 18:21:02 +00008056- A few crashers fixed: weakref_in_del.py (issue #1377858);
8057 loosing_dict_ref.py (issue #1303614, test67.py);
8058 borrowed_ref_[34].py (not in tracker).
8059
Vinay Sajipd7cf32e2008-01-24 12:43:33 +00008060- Issue #1069410: The "can't load dll" message box on Windows is
Christian Heimesb2302ba2008-01-23 17:15:06 +00008061 suppressed while an extension is loaded by calling SetErrorMode in
8062 dynload_win.c. The error is still reported properly.
8063
Georg Brandl3ee81df2008-05-17 18:14:43 +00008064- Issue #1915: Python compiles with --enable-unicode=no again. However
Christian Heimes082c9b02008-01-23 14:20:50 +00008065 several extension methods and modules do not work without unicode
8066 support.
8067
Georg Brandl26543b12008-01-21 18:36:51 +00008068- Issue #1882: when compiling code from a string, encoding cookies in the
8069 second line of code were not always recognized correctly.
8070
Georg Brandl14404b62008-01-19 19:27:05 +00008071- Issue #1679: "0x" was taken as a valid integer literal.
8072
Georg Brandl6caad7d2008-01-26 14:19:22 +00008073- Issue #1865: ``bytes`` as an alias for ``str`` and b"" as an alias "" were
Christian Heimes288e89a2008-01-18 18:24:07 +00008074 added.
8075
Christian Heimesc94e2b52008-01-14 04:13:37 +00008076- sys.float_info / PyFloat_GetInfo: The floating point information
8077 object was converted from a dict to a specialized structseq object.
8078
Georg Brandl3ee81df2008-05-17 18:14:43 +00008079- Patch #1816: Added sys.flags structseq. It exposes the status of
8080 most command line arguments and PYTHON* environment variables.
Christian Heimesf31b69f2008-01-14 03:42:48 +00008081
Georg Brandl3ee81df2008-05-17 18:14:43 +00008082- Objects/structseq.c: Implemented new structseq representation. The
8083 patch makes structseqs (e.g. the return value of os.stat) more
8084 readable.
Christian Heimes9c201962008-01-14 03:33:52 +00008085
Georg Brandl3ee81df2008-05-17 18:14:43 +00008086- Patch #1700288: added a type attribute cache that caches method
8087 accesses, resulting in speedups in heavily object-oriented code.
Amaury Forgeot d'Arce4c270c2008-01-14 00:29:41 +00008088
Neal Norwitz3fc15b82008-01-10 05:42:58 +00008089- Bug #1776: __import__() no longer accepts filenames on any platform.

8093
Georg Brandl3ee81df2008-05-17 18:14:43 +00008094- Patch #602345: Add -B command line option, PYTHONDONTWRITEBYTECODE
8095 envvar and sys.dont_write_bytecode attribute. All these can be set
8096 to forbid Python to attempt to write compiled bytecode files.
Georg Brandl2da0fce2008-01-07 17:09:35 +00008097
Georg Brandl3ee81df2008-05-17 18:14:43 +00008098- Improve some exception messages when Windows fails to load an
8099 extension module. Now we get for example '%1 is not a valid Win32
8100 application' instead of 'error code 193'.
Amaury Forgeot d'Arce0b76952008-01-04 02:04:15 +00008101

8105 y) functions.
Christian Heimese2ca4242008-01-03 20:23:15 +00008106
Christian Heimes0a8143f2007-12-18 23:22:54 +00008107- Issue #1635: Platform independent creation and representation of NaN
Georg Brandl3ee81df2008-05-17 18:14:43 +00008108 and INF. float("nan"), float("inf") and float("-inf") now work on
8109 every platform with IEEE 754 semantics.
Christian Heimes0a8143f2007-12-18 23:22:54 +00008110
Georg Brandl3ee81df2008-05-17 18:14:43 +00008111- Compiler now generates simpler and faster code for dictionary
8112 literals. The oparg for BUILD_MAP now indicates an estimated
8113 dictionary size. There is a new opcode, STORE_MAP, for adding
8114 entries to the dictionary.

Georg Brandl3ee81df2008-05-17 18:14:43 +00008148- Issue #1265: Fix a problem with sys.settrace, if the tracing
8149 function uses a generator expression when at the same time the
8150 executed code is closing a paused generator.
Amaury Forgeot d'Arc0d75f092007-11-13 21:54:28 +00008151
Raymond Hettinger1760c8a2007-11-08 02:52:43 +00008152- sets and frozensets now have an isdisjoint() method.

8157
Georg Brandl21e99f42010-03-07 15:23:59 +00008158- The enumerate() built-in function is no longer bounded to sequences
Georg Brandl3ee81df2008-05-17 18:14:43 +00008159 smaller than LONG_MAX. Formerly, it raised an OverflowError. Now,
8160 automatically shifts from ints to longs.
Raymond Hettinger8f669372007-10-03 21:18:11 +00008161
Georg Brandl3ee81df2008-05-17 18:14:43 +00008162- Issue #1686386: Tuple's tp_repr did not take into account the
8163 possibility of having a self-referential tuple, which is possible
8164 from C code. Nor did object's tp_str consider that a type's tp_str
8165 could do something that could lead to an inifinite recursion.
8166 Py_ReprEnter() and Py_EnterRecursiveCall(), respectively, fixed the
8167 issues.

Georg Brandl3ee81df2008-05-17 18:14:43 +00008169- Issue #1164: It was possible to trigger deadlock when using the
8170 'print' statement to write to a file since the GIL was not released
8171 as needed. Now PyObject_Print() does the right thing along with
8172 various tp_print implementations of the built-in types and those in
8173 the collections module.
Brett Cannon01531592007-09-17 03:28:34 +00008174
Georg Brandl3ee81df2008-05-17 18:14:43 +00008175- Issue #1147: Exceptions were directly allowing string exceptions in
8176 their throw() method even though string exceptions no longer
8177 allowed.
Brett Cannon4c20bc42007-09-11 21:02:28 +00008178
Georg Brandl3ee81df2008-05-17 18:14:43 +00008179- Issue #1096: Prevent a segfault from getting the repr of a very
8180 deeply nested list by using the recursion counter.
Brett Cannona0c05512007-09-10 21:38:27 +00008181
Brett Cannon1e534b52007-09-07 04:18:30 +00008182- Issue #1202533: Fix infinite recursion calls triggered by calls to
Georg Brandl3ee81df2008-05-17 18:14:43 +00008183 PyObject_Call() never calling back out to Python code to trigger
8184 recursion depth updates/checks. Required the creation of a static
8185 RuntimeError instance in case normalizing an exception put the
8186 recursion check value past its limit. Fixes crashers
8187 infinite_rec_(1|2|4|5).py.
Brett Cannon1e534b52007-09-07 04:18:30 +00008188
Georg Brandl3ee81df2008-05-17 18:14:43 +00008189- Patch #1031213: Decode source line in SyntaxErrors back to its
8190 original source encoding.

8193 with %G.
8194
Georg Brandl3ee81df2008-05-17 18:14:43 +00008195- Prevent expandtabs() on string and unicode objects from causing a
8196 segfault when a large width is passed on 32-bit platforms.
Neal Norwitz7dbd2a32007-06-09 03:36:34 +00008197
Georg Brandl3ee81df2008-05-17 18:14:43 +00008198- Issue #1733488: Fix compilation of bufferobject.c on AIX.
Martin v. Löwisda587ab2007-06-08 17:29:20 +00008199
Georg Brandl3ee81df2008-05-17 18:14:43 +00008200- Issue #1722485: remove docstrings again when running with -OO.
Georg Brandla5ea6892007-06-01 11:33:33 +00008201
Neal Norwitz0ac60192007-05-27 04:08:54 +00008202- Add new attribute names for function objects. All the func_* become
Georg Brandl3ee81df2008-05-17 18:14:43 +00008203 __*__ attributes. (Some already existed, e.g., __doc__ and
8204 __name__.)
Neal Norwitz0ac60192007-05-27 04:08:54 +00008205
Neal Norwitz8b2bfbc2007-05-23 06:35:32 +00008206- Add -3 option to the interpreter to warn about features that are
8207 deprecated and will be changed/removed in Python 3.0.
8208
Georg Brandl2134e752007-05-21 20:34:16 +00008209- Patch #1686487: you can now pass any mapping after '**' in function
8210 calls.
8211
Collin Winter62903052007-05-18 23:11:24 +00008212- except clauses may now be spelled either "except E, target:" or
Georg Brandl3ee81df2008-05-17 18:14:43 +00008213 "except E as target:". This is to provide forwards compatibility
8214 with Python 3.0.
Collin Winter62903052007-05-18 23:11:24 +00008215
Brett Cannon229cee22007-05-05 01:34:02 +00008216- Deprecate BaseException.message as per PEP 352.
8217
Georg Brandl3ee81df2008-05-17 18:14:43 +00008218- Issue #1303614: don't expose object's __dict__ when the dict is
Georg Brandl21e99f42010-03-07 15:23:59 +00008219 inherited from a built-in base.
Armin Rigo9790a272007-05-02 19:23:31 +00008220
Vinay Sajip8549ce32007-05-06 17:53:37 +00008221- When __slots__ are set to a unicode string, make it work the same as
Neal Norwitzcbd9ee62007-04-14 05:25:50 +00008222 setting a plain string, ie don't expand to single letter identifiers.
8223
Raymond Hettinger13936692007-04-11 18:40:58 +00008224- Request #1191699: Slices can now be pickled.
8225
Raymond Hettinger4db5fe92007-04-12 04:10:00 +00008226- Request #1193128: str.translate() now allows a None argument for
8227 translations that only remove characters without re-mapping the
8228 remaining characters.
8229
Georg Brandl5cb76c12007-03-21 09:00:39 +00008230- Patch #1682205: a TypeError while unpacking an iterable is no longer
8231 masked by a generic one with the message "unpack non-sequence".
8232
Neal Norwitzaa754b72007-03-21 06:39:48 +00008233- Remove unused file Python/fmod.c.
8234
Guido van Rossum143b5642007-03-23 04:58:42 +00008235- Bug #1683368: The object.__init__() and object.__new__() methods are
8236 now stricter in rejecting excess arguments. The only time when
8237 either allows excess arguments is when it is not overridden and the
8238 other one is. For backwards compatibility, when both are
8239 overridden, it is a deprecation warning (for now; maybe a Py3k
Guido van Rossum234b1ff2007-03-23 19:39:01 +00008240 warning later). Also, type.__init__() insists on the same signature
8241 as supported by type.__new__().
Guido van Rossum143b5642007-03-23 04:58:42 +00008242
Georg Brandl3ee81df2008-05-17 18:14:43 +00008243- Patch #1675423: PyComplex_AsCComplex() now tries to convert an
8244 object to complex using its __complex__() method before falling back
8245 to the __float__() method. Therefore, the functions in the cmath
8246 module now can operate on objects that define a __complex__()
8247 method.
Georg Brandl2b869942007-03-17 16:08:45 +00008248
Georg Brandl3ee81df2008-05-17 18:14:43 +00008249- Patch #1623563: allow __class__ assignment for classes with
8250 __slots__. The old and the new class are still required to have the
8251 same slot names.
Žiga Seilnacht6f2d09c2007-03-16 11:59:38 +00008252
Georg Brandl3ee81df2008-05-17 18:14:43 +00008253- Patch #1642547: Fix an error/crash when encountering syntax errors
8254 in complex if statements.

Georg Brandl3ee81df2008-05-17 18:14:43 +00008256- Patch #1462488: Python no longer segfaults when
8257 ``object.__reduce_ex__()`` is called with an object that is faking
8258 its type.
Žiga Seilnacht20f43d32007-03-15 11:44:55 +00008259
Georg Brandl3ee81df2008-05-17 18:14:43 +00008260- Patch #1680015: Don't modify __slots__ tuple if it contains an
8261 unicode name.
Žiga Seilnacht71436f02007-03-14 12:24:09 +00008262
Georg Brandl5240d742007-03-13 20:46:32 +00008263- Patch #1444529: the builtin compile() now accepts keyword arguments.
8264
Georg Brandl7b9c5552007-03-12 14:30:05 +00008265- Bug #1678647: write a newline after printing an exception in any
8266 case, even when converting the value to a string failed.
8267
Georg Brandl871f1bc2007-03-12 13:17:36 +00008268- The dir() function has been extended to call the __dir__() method on
Georg Brandl3ee81df2008-05-17 18:14:43 +00008269 its argument, if it exists. If not, it will work like before. This
8270 allows customizing the output of dir() in the presence of a
8271 __getattr__().
Georg Brandl871f1bc2007-03-12 13:17:36 +00008272
Collin Winter276887b2007-03-12 16:11:39 +00008273- Patch #922167: Python no longer segfaults when faced with infinitely
8274 self-recursive reload() calls (as reported by bug #742342).
8275
Georg Brandl3ee81df2008-05-17 18:14:43 +00008276- Patch #1675981: remove unreachable code from ``type.__new__()``
8277 method.

Georg Brandl3ee81df2008-05-17 18:14:43 +00008279- Patch #1491866: change the complex() constructor to allow
8280 parthensized forms. This means complex(repr(x)) now works instead of
8281 raising a ValueError.
Collin Wintere38051d2007-03-09 20:33:07 +00008282
Georg Brandlaa2321b2007-03-07 00:40:28 +00008283- Patch #703779: unset __file__ in __main__ after running a file. This
Georg Brandl3ee81df2008-05-17 18:14:43 +00008284 makes the filenames the warning module prints much more sensible
8285 when a PYTHONSTARTUP file is used.
Georg Brandlaa2321b2007-03-07 00:40:28 +00008286
Georg Brandl49aafc92007-03-07 00:34:46 +00008287- Variant of patch #697613: don't exit the interpreter on a SystemExit
8288 exception if the -i command line option or PYTHONINSPECT environment
Georg Brandl3ee81df2008-05-17 18:14:43 +00008289 variable is given, but break into the interactive interpreter just
8290 like on other exceptions or normal program exit.

Georg Brandl3ee81df2008-05-17 18:14:43 +00008295- Bug #1674503: close the file opened by execfile() in an error
8296 condition.
Georg Brandl098cd692007-03-06 12:17:50 +00008297
Georg Brandl0fca97a2007-03-05 22:28:08 +00008298- Patch #1674228: when assigning a slice (old-style), check for the
8299 sq_ass_slice instead of the sq_slice slot.
8300
Georg Brandl3ee81df2008-05-17 18:14:43 +00008301- When printing an unraisable error, don't print exceptions. before
8302 the name. This duplicates the behavior whening normally printing
8303 exceptions.
Neal Norwitz88516a62007-02-26 22:41:45 +00008304
Georg Brandl3ee81df2008-05-17 18:14:43 +00008305- Bug #1653736: Properly discard third argument to

Georg Brandl3ee81df2008-05-17 18:14:43 +00008311- Bug #1377858: Fix the segfaulting of the interpreter when an object
8312 created a weakref on itself during a __del__ call for new-style
8313 classes (classic classes still have the bug).
Brett Cannonf5bee302007-01-23 23:21:22 +00008314
Martin v. Löwis6c5c5022007-01-23 21:11:47 +00008315- Bug #1579370: Make PyTraceBack_Here use the current thread, not the

8360
Armin Rigo7ccbca92006-10-04 12:17:45 +00008361- A number of places, including integer negation and absolute value,
8362 were fixed to not rely on undefined behaviour of the C compiler
8363 anymore.

8366 number of arguments, as was the case in Python 2.4.
8367
Georg Brandl5d59c092006-09-30 08:43:30 +00008368- Patch #1567691: super() and new.instancemethod() now don't accept
Georg Brandl3ee81df2008-05-17 18:14:43 +00008369 keyword arguments any more (previously they accepted them, but
8370 didn't use them).

Georg Brandl3ee81df2008-05-17 18:14:43 +00008372- Fix a bug in the parser's future statement handling that led to
8373 "with" not being recognized as a keyword after, e.g., this
8374 statement: from __future__ import division, with_statement
Georg Brandla10d3af2006-09-24 12:35:36 +00008375

8383 method. This allows calling unicode() on exceptions classes
8384 directly to succeed.
Brett Cannon9adeab72006-09-20 18:34:28 +00008385
Georg Brandl4e933132006-09-06 20:05:58 +00008386- Bug #1542051: Exceptions now correctly call PyObject_GC_UnTrack.

8401 head is the original string if sep was not found.
8402
Neal Norwitzdac090d2006-09-05 03:53:08 +00008403- Bug #1520864: unpacking singleton tuples in list comprehensions and
Georg Brandl3ee81df2008-05-17 18:14:43 +00008404 generator expressions (x for x, in ... ) works again. Fixing this
8405 problem required changing the .pyc magic number. This means that
8406 .pyc files generated before 2.5c2 will be regenerated.
Neal Norwitzdac090d2006-09-05 03:53:08 +00008407

8911 Python would crash instead of raising an error.
8912

8929 incompatibility since it never made sense with ordinary subclasses
8930 -- the failure just occurred later, with a more cumbersome
8931 exception.

9208 obtained from the TLS negotiation itself. Patch contributed by Bill
9209 Fenner.
Gregory P. Smith2b3ba582008-01-17 08:03:17 +00009210
Georg Brandl3ee81df2008-05-17 18:14:43 +00009211- Issue #1339: The smtplib.SMTP class has been refactored a bit such
Gregory P. Smithbde4ae42008-01-17 08:35:49 +00009212 that the SMTP.starttls() caller no longer needs to call ehlo()
9213 beforehand. SMTP.starttls() now raises an exception of the server
Georg Brandl3ee81df2008-05-17 18:14:43 +00009214 does not claim to support starttls. Adds the
9215 SMTP.ehlo_or_helo_if_needed() method. Patch contributed by Bill

9296 complex, tuple, list, dict, set, and frozenset. Formerly, it would
9297 silently miscode subclasses of those types. Now, it raises a

Georg Brandl3ee81df2008-05-17 18:14:43 +00009314 time so that opening a database previously created with the DB_DUP
9315 or DB_DUPSORT flag set will keep the proper behavior on subsequent
9316 opens. Specifically: dictionary assignment to a DB object will
9317 replace all values for a given key when the database allows
9318 duplicate values. DB users should use DB.put(k, v) when they want
9319 to store duplicates; not DB[k] = v.

9326 characters with ASCII value less than 32. Also, it correctly quotes
9327 dots only if they occur on a single line, as opposed to the previous
9328 behavior of quoting dots if they are the second character of any
9329 line.

9657-----
9658
Georg Brandl3ee81df2008-05-17 18:14:43 +00009659- Unified naming convention for free lists and their limits. All free
9660 lists in Object/ are named ``free_list``, the counter ``numfree``
9661 and the upper limit is a macro ``PyName_MAXFREELIST`` inside an
9662 #ifndef block.
Christian Heimes5b970ad2008-02-06 13:33:44 +00009663
Georg Brandl3ee81df2008-05-17 18:14:43 +00009664- ``PySet_Add()`` can now modify a newly created frozenset. Similarly
9665 to ``PyTuple_SetItem``, it can be used to populate a brand new
9666 frozenset; but it does not steal a reference to the added item.
Amaury Forgeot d'Arccab3d982008-02-03 22:51:43 +00009667
Vinay Sajipb7edfc42008-04-02 21:10:23 +00009668- Added ``PySet_Check()`` and ``PyFrozenSet_Check()`` to the set API.

Georg Brandl3ee81df2008-05-17 18:14:43 +00009670- Backport of PyUnicode_FromString(), _FromStringAndSize(), _Format
9671 and _FormatV from Python 3.0. Made PyLong_AsSsize_t and
9672 PyLong_FromSsize_t public functions.
Georg Brandl6caad7d2008-01-26 14:19:22 +00009673
9674- Patch #1720595: add T_BOOL to the range of structmember types.
9675
9676- Issue #1534: Added ``PyFloat_GetMax()``, ``PyFloat_GetMin()`` and
9677 ``PyFloat_GetInfo()`` to the float API.
9678
Georg Brandl3ee81df2008-05-17 18:14:43 +00009679- Issue #1521: On 64bit platforms, using PyArgs_ParseTuple with the t#
9680 of w# format code incorrectly truncated the length to an int, even
9681 when PY_SSIZE_T_CLEAN is set. The str.decode method used to return
9682 incorrect results with huge strings.
Georg Brandl6caad7d2008-01-26 14:19:22 +00009683
Georg Brandl3ee81df2008-05-17 18:14:43 +00009684- Issue #1629: Renamed Py_Size, Py_Type and Py_Refcnt to Py_SIZE,
9685 Py_TYPE and Py_REFCNT.

Georg Brandl3ee81df2008-05-17 18:14:43 +00009687- PEP 3123: Provide forward compatibility with Python 3.0, while
9688 keeping backwards compatibility. Add Py_Refcnt, Py_Type, Py_Size,
9689 and PyVarObject_HEAD_INIT.

Georg Brandl3ee81df2008-05-17 18:14:43 +00009691- Py_ssize_t fields work in structmember when HAVE_LONG_LONG is not
9692 defined.
Georg Brandl6caad7d2008-01-26 14:19:22 +00009693
9694- Patch #1733960: Allow T_LONGLONG to accept ints.

9702- Fix some leftovers from the conversion from int to Py_ssize_t
9703 (relevant to strings and sequences of more than 2**31 items).
9704
9705- Make _PyGILState_NoteThreadState() static, it was not used anywhere
9706 outside of pystate.c and should not be necessary.
9707
Georg Brandl3ee81df2008-05-17 18:14:43 +00009708- ``PyImport_Import`` and ``PyImport_ImportModule`` now always do
9709 absolute imports. In earlier versions they might have used relative
9710 imports under some conditions.
Christian Heimes000a0742008-01-03 22:16:32 +00009711
Georg Brandl3ee81df2008-05-17 18:14:43 +00009712- Added case insensitive comparison methods ``PyOS_stricmp(char*,
9713 char*)`` and ``PyOS_strnicmp(char*, char*, Py_ssize_t)``.
Christian Heimes000a0742008-01-03 22:16:32 +00009714
Georg Brandl3ee81df2008-05-17 18:14:43 +00009715- Bug #1542693: remove semi-colon at end of PyImport_ImportModuleEx

Georg Brandl3ee81df2008-05-17 18:14:43 +00009721- Patch #1706: Drop support for Win9x, WinME and NT4. Python now
9722 requires Windows 2000 or greater. The _WINVER and NTDDI_VERSION
9723 macros are set to Win2k for x86/32bit builds and WinXP for AMD64
9724 builds.
Christian Heimes95d64472008-02-09 19:55:22 +00009725
Georg Brandl3ee81df2008-05-17 18:14:43 +00009726- Conditionalize definition of _CRT_SECURE_NO_DEPRECATE and

Georg Brandl3ee81df2008-05-17 18:14:43 +00009738- Removed the macfs module. It had been deprecated since Python 2.5.
9739 This lead to the deprecation of macostools.touched() as it relied
9740 solely on macfs and was a no-op under OS X.
