Ned Deily0203a802013-10-25 00:40:07 -0700293- Issue #15663: Tcl/Tk 8.5.15 is now included with the OS X 10.6+
294 64-bit/32-bit installer for 10.6+. It is no longer necessary
295 to install a third-party version of Tcl/Tk 8.5 to work around the
296 problems in the Apple-supplied Tcl/Tk 8.5 shipped in OS X 10.6
297 and later releases.

Ned Deilyf84b5312013-10-25 00:44:46 -0700299- Issue #19019: Change the OS X installer build script to use CFLAGS instead
300 of OPT for special build options. By setting OPT, some compiler-specific
301 options like -fwrapv were overridden and thus not used, which could result
302 in broken interpreters when building with clang.

1349 In particular, fix extension module build failures when trying to use
1350 32-bit-only installer Pythons on systems with Xcode 4 (currently
1351 OS X 10.8, 10.7, and optionally 10.6).
1352 * Backport 3.3.0 fixes to 2.7 branch (for release in 2.7.4)
1353 * Since Xcode 4 removes ppc support, extension module builds now
1354 check for ppc compiler support and by default remove ppc and
1355 ppc64 archs when they are not available.
1356 * Extension module builds now revert to using system installed
1357 headers and libs (/usr and /System/Library) if the SDK used
1358 to build the interpreter is not installed or has moved.
1359 * Try to avoid building extension modules with deprecated
1360 and problematic Apple llvm-gcc compiler. If original compiler
1361 is not available, use clang instead by default.

Florent Xiclunac2279652012-02-12 14:49:03 +01001785- Issue #13994: Earlier partial revert of Distutils enhancements in 2.7
Ned Deilyc47a4592012-02-11 20:40:24 +01001786 has left two versions of customize_compiler, the original in
1787 distutils.sysconfig and another copy in distutils.ccompiler, with some
1788 parts of distutils calling one and others using the other.

1790 is the case in 3.x.

Ned Deily0d0ea482012-02-10 12:59:06 +01001792- Issue #13590: On OS X 10.7 and 10.6 with Xcode 4.2, building
1793 Distutils-based packages with C extension modules may fail because
1794 Apple has removed gcc-4.2, the version used to build python.org
1795 64-bit/32-bit Pythons. If the user does not explicitly override
1796 the default C compiler by setting the CC environment variable,
1797 Distutils will now attempt to compile extension modules with clang
1798 if gcc-4.2 is required but not found. Also as a convenience, if
1799 the user does explicitly set CC, substitute its value as the default
1800 compiler in the Distutils LDSHARED configuration variable for OS X.
1801 (Note, the python.org 32-bit-only Pythons use gcc-4.0 and the 10.4u
1802 SDK, neither of which are available in Xcode 4. This change does not
1803 attempt to override settings to support their use with Xcode 4.)
1804

1871 raised when the wrapped raw file is non-blocking and the write would block.

Ned Deily87e82bb2011-06-28 19:52:59 -07002053- Issue #9516: On Mac OS X, change Distutils to no longer globally attempt to
2054 check or set the MACOSX_DEPLOYMENT_TARGET environment variable for the
2055 interpreter process. This could cause failures in non-Distutils subprocesses
2056 and was unreliable since tests or user programs could modify the interpreter
Ezio Melotti302ad8d2013-01-19 19:44:58 +02002057 environment after Distutils set it. Instead, have Distutils set the
Ned Deily87e82bb2011-06-28 19:52:59 -07002058 deployment target only in the environment of each build subprocess. It is
2059 still possible to globally override the default by setting
2060 MACOSX_DEPLOYMENT_TARGET before launching the interpreter; its value must be
2061 greater or equal to the default value, the value with which the interpreter
2062 was built.

2091 updating the check interval, so if the user decreases the check interval,
2092 the ticker doesn't have to wind down to zero from the old starting point
2093 before the new interval takes effect. And if the user increases the
2094 interval, it makes sure the new limit takes effect right away rather have an
2095 early task switch before recognizing the new interval.

3076 This prevents user-created self-referencing ordered dictionaries from
3077 becoming permanently uncollectable GC garbage. The downside is that

3537
Ezio Melottiab2eb0e2010-06-05 19:21:32 +00003538- Issue #8271: during the decoding of an invalid UTF-8 byte sequence, only the
3539 start byte and the continuation byte(s) are now considered invalid, instead
3540 of the number of bytes specified by the start byte.
3541 E.g.: '\xf1\x80AB'.decode('utf-8', 'replace') now returns u'\ufffdAB' and
3542 replaces with U+FFFD only the start byte ('\xf1') and the continuation byte
3543 ('\x80') even if '\xf1' is the start byte of a 4-bytes sequence.
3544 Previous versions returned a single u'\ufffd'.

Mark Dickinson23f0d6b2010-06-05 11:52:24 +00003546- Issue #8627: Remove bogus "Overriding __cmp__ blocks inheritance of

3548 arises from the "Overriding __eq__ blocks inheritance ..." warning
3549 when turned into an exception: in this case the exception simply
3550 gets ignored.

Mark Dickinson4ca7c3c2010-05-30 13:18:10 +00003552- Issue #8748: Fix two issues with comparisons between complex and integer
3553 objects. (1) The comparison could incorrectly return True in some cases
3554 (2**53+1 == complex(2**53) == 2**53), breaking transivity of equality.
3555 (2) The comparison raised an OverflowError for large integers, leading
3556 to unpredictable exceptions when combining integers and complex objects
3557 in sets or dicts.
3558
Mark Dickinson81336372010-05-30 12:12:25 +00003559- Issue #5211: Implicit coercion for the complex type is now completely
3560 removed. (Coercion for arithmetic operations was already removed in 2.7
3561 alpha 4, but coercion for rich comparisons was accidentally left in.)
3562
Victor Stinnerc49dfcc2010-05-25 22:30:32 +00003563- Issue #3798: Write sys.exit() message to sys.stderr to use stderr encoding

Georg Brandlfee0f442010-05-22 21:26:21 +00003750- Issue #8567: Fix precedence of signals in Decimal module: when a Decimal
3751 operation raises multiple signals and more than one of those signals is
3752 trapped, the specification determines the order in which the signals should be
3753 handled. In many cases this order wasn't being followed, leading to the wrong
3754 Python exception being raised.

3940 with a non-empty format string. This is an effort to future-proof user
3941 code. If a derived class does not currently implement __format__ but later
3942 adds its own __format__, it would most likely break user code that had
Antoine Pitrou01a196a2011-01-02 20:05:11 +00003943 supplied a format string. This will be changed to a DeprecationWarning in
Georg Brandlfee0f442010-05-22 21:26:21 +00003944 Python 3.3 and it will be an error in Python 3.4.

Georg Brandlfee0f442010-05-22 21:26:21 +00003994- Issue #7279: Comparisons involving a Decimal signaling NaN now signal
3995 InvalidOperation instead of returning False. (Comparisons involving a quiet
3996 NaN are unchanged.) Also, Decimal quiet NaNs are now hashable; Decimal
3997 signaling NaNs remain unhashable.

Georg Brandlfee0f442010-05-22 21:26:21 +00003999- Issue #2531: Comparison operations between floats and Decimal instances now
4000 return a result based on the numeric values of the operands; previously they
4001 returned an arbitrary result based on the relative ordering of id(float) and
4002 id(Decimal).

Barry Warsawf7f2d6f2010-03-31 21:07:16 +00004004- Issue #8233: When run as a script, py_compile.py optionally takes a single
Georg Brandlfee0f442010-05-22 21:26:21 +00004005 argument `-` which tells it to read files to compile from stdin. Each line is
4006 read on demand and the named file is compiled immediately. (Original patch by
4007 Piotr Ożarowski).

4017 Fractions instance now raise TypeError instead of returning True/False. This
4018 makes Fraction <=> complex comparisons consistent with int <=> complex, float
4019 <=> complex, and complex <=> complex comparisons.

4119 integer format code, struct.pack first attempts to convert the non-integer

4122
Georg Brandlba83f822010-03-14 09:50:54 +00004123- Issue #1530559: When passing a non-integer argument to struct.pack with *any*
4124 integer format code (one of 'bBhHiIlLqQ'), struct.pack attempts to use the
4125 argument's __int__ method to convert to an integer before packing. It also
Georg Brandlfee0f442010-05-22 21:26:21 +00004126 produces a DeprecationWarning in this case. (In Python 2.6, the behaviour was
4127 inconsistent: __int__ was used for some integer codes but not for others, and
4128 the set of integer codes for which it was used differed between native packing
4129 and standard packing.)

Georg Brandlba83f822010-03-14 09:50:54 +00004437 file position when calling `truncate()`. It would previously change the file
4438 position to the given argument, which goes against the tradition of

4442 class used to represent files stored inside an archive. The new
4443 implementation is significantly faster and can be wrapped in a

4445 where interleaved calls to ``read()`` and ``readline()`` give wrong results.

4534-----------------
4535
Georg Brandlba83f822010-03-14 09:50:54 +00004536- The ``__complex__()`` method is now looked up on the class of instances to
4537 make it consistent with other special methods.

4541
Mark Dickinson1b34d252010-01-01 17:27:30 +00004542- Issue #5080: A number of functions and methods previously produced a
Georg Brandlba83f822010-03-14 09:50:54 +00004543 DeprecationWarning when passed a float argument where an integer was expected.
4544 These functions and methods now raise TypeError instead. The majority of the
4545 effects of this change are in the extension modules, but some core functions
4546 and methods are affected: notably the 'chr', 'range' and 'xrange' builtins,
4547 and many unicode/str methods.

4559
Georg Brandlba83f822010-03-14 09:50:54 +00004560- Issue #1811: Improve accuracy and cross-platform consistency for true division
4561 of integers: the result of a/b is now correctly rounded for ints a and b (at
4562 least on IEEE 754 platforms), and in particular does not depend on the
4563 internal representation of a long.

4571
Georg Brandlba83f822010-03-14 09:50:54 +00004572 These executables now work properly with the arch(1) command: ``arch -ppc

Georg Brandlba83f822010-03-14 09:50:54 +00004708- Issue #7419: ``locale.setlocale()`` could crash the interpreter on Windows
4709 when called with invalid values.

Georg Brandlba83f822010-03-14 09:50:54 +00004711- Issue #3382: 'F' formatting for float and complex now convert the result to
4712 upper case. This only affects 'inf' and 'nan', since 'f' no longer converts
4713 to 'g' for large values.
Amaury Forgeot d'Arcd7288712009-12-01 21:51:04 +00004714
Georg Brandlba83f822010-03-14 09:50:54 +00004715- Remove switch from "%f" formatting to "%g" formatting for floats larger than
4716 1e50 in absolute value.
Mark Dickinson9dd5e162009-11-23 20:54:09 +00004717
Georg Brandlba83f822010-03-14 09:50:54 +00004718- Remove restrictions on precision when formatting floats. E.g., "%.120g" %
4719 1e-100 used to raise OverflowError, but now gives the requested 120
4720 significant digits instead.
Mark Dickinson18cfada2009-11-23 18:46:41 +00004721
Georg Brandlba83f822010-03-14 09:50:54 +00004722- Add Py3k warnings for parameter names in parentheses.

Benjamin Peterson89b1a5c2009-11-19 22:58:01 +00004725
Georg Brandlba83f822010-03-14 09:50:54 +00004726- Issue #7085: Fix crash when importing some extensions in a thread on MacOSX
4727 10.6.
Ronald Oussoren315cd0c2009-11-19 16:25:21 +00004728
Georg Brandlba83f822010-03-14 09:50:54 +00004729- Issue #7117: ``repr(x)`` for a float x returns a result based on the shortest
4730 decimal string that's guaranteed to round back to x under correct rounding
4731 (with round-half-to-even rounding mode). Previously it gave a string based on
4732 rounding x to 17 decimal digits. repr(x) for a complex number behaves
4733 similarly. On platforms where the correctly-rounded strtod and dtoa code is
4734 not supported (see below), repr is unchanged.
Mark Dickinsonb678de82009-11-19 18:41:49 +00004735
Georg Brandlba83f822010-03-14 09:50:54 +00004736- Issue #7117: On almost all platforms: float-to-string and string-to-float
4737 conversions within Python are now correctly rounded. Places these conversions
4738 occur include: str for floats and complex numbers; the float and complex
4739 constructors; old-style and new-style numeric formatting; serialization and
4740 deserialization of floats and complex numbers using marshal, pickle and json;
4741 parsing of float and imaginary literals in Python code; Decimal-to-float
4742 conversion.
Mark Dickinsonb678de82009-11-19 18:41:49 +00004743
Georg Brandlba83f822010-03-14 09:50:54 +00004744 The conversions use a Python-adapted version of David Gay's well-known dtoa.c,
4745 providing correctly-rounded strtod and dtoa C functions. This code is
4746 supported on Windows, and on Unix-like platforms using gcc, icc or suncc as
4747 the C compiler. There may be a small number of platforms on which correct
4748 operation of this code cannot be guaranteed, so the code is not used: notably,
4749 this applies to platforms where the C double format is not IEEE 754 binary64,
4750 and to platforms on x86 hardware where the x87 FPU is set to 64-bit precision
4751 and Python's configure script is unable to determine how to change the FPU
4752 precision. On these platforms conversions use the platform strtod and dtoa,
4753 as before.
Mark Dickinsonb678de82009-11-19 18:41:49 +00004754
Georg Brandlba83f822010-03-14 09:50:54 +00004755- Issue #7117: Backport round implementation from Python 3.x. ``round()`` now
4756 uses the correctly-rounded string <-> float conversions described above (when
4757 available), and so produces correctly rounded results that will display nicely
4758 under the float repr. There are two related small changes: (1) round now
4759 accepts any class with an ``__index__()`` method for its second argument (but
4760 no longer accepts floats for the second argument), and (2) an excessively
4761 large second integer argument (e.g., ``round(1.234, 10**100)``) no longer
4762 raises an exception.

Philip Jenveyfab8be22009-11-17 02:42:26 +00004764- Issue #1757126: Fix the cyrillic-asian alias for the ptcp154 encoding.
4765
Georg Brandlba83f822010-03-14 09:50:54 +00004766- Fix several issues with ``compile()``. The input can now contain Windows and
4767 Mac newlines and is no longer required to end in a newline.
Benjamin Petersone36199b2009-11-12 23:39:44 +00004768

Amaury Forgeot d'Arcd0052d12009-10-06 19:56:32 +00004797- Issue #1571184: The Unicode database contains properties for more characters.
4798 The tables for code points representing numeric values, white spaces or line
4799 breaks are now generated from the official Unicode Character Database files,
4800 and include information from the Unihan.txt file.

Georg Brandlba83f822010-03-14 09:50:54 +00004909- Issue #5920: For ``float.__format__()``, change the behavior with the empty
4910 presentation type (that is, not one of 'e', 'f', 'g', or 'n') to be like 'g'
4911 but with at least one decimal point and with a default precision
4912 of 12. Previously, the behavior the same but with a default precision of 6.
4913 This more closely matches ``str()``, and reduces surprises when adding
4914 alignment flags to the empty presentation type. This also affects the new
4915 complex.__format__ in the same way.

Georg Brandlba83f822010-03-14 09:50:54 +00004924- Issue #1588: Add complex.__format__. For example, ``format(complex(1, 2./3),
4925 '.5')`` now produces a sensible result.
Eric Smith9139cc62009-04-30 00:58:58 +00004926
Georg Brandlba83f822010-03-14 09:50:54 +00004927- Issue #5864: Fix empty format code formatting for floats so that it never
4928 gives more than the requested number of significant digits.
Mark Dickinson92fcc9c2009-04-29 20:41:00 +00004929
Georg Brandlba83f822010-03-14 09:50:54 +00004930- Issue #5793: Rationalize isdigit / isalpha / tolower, etc. Includes new

Eric Smith068f0652009-04-25 21:40:15 +00004936- Issue #5835: Deprecate PyOS_ascii_formatd and replace it with
4937 _PyOS_double_to_string or PyOS_double_to_string.
4938
Benjamin Peterson5083dc52009-04-25 00:41:22 +00004939- Issue #5283: Setting __class__ in __del__ caused a segfault.

Georg Brandlba83f822010-03-14 09:50:54 +00004959- Issue #1869: Fix a couple of minor round() issues. ``round(5e15+1)`` was
4960 giving 5e15+2; ``round(-0.0)`` was losing the sign of the zero.

Antoine Pitrouf8387af2009-03-23 18:41:45 +00004979- Issue #4688: Add a heuristic so that tuples and dicts containing only
Georg Brandlba83f822010-03-14 09:50:54 +00004980 untrackable objects are not tracked by the garbage collector. This can reduce
4981 the size of collections and therefore the garbage collection overhead on
4982 long-running programs, depending on their particular use of datatypes.
Antoine Pitrouf8387af2009-03-23 18:41:45 +00004983
Georg Brandlba83f822010-03-14 09:50:54 +00004984- Issue #5512: Rewrite PyLong long division algorithm (x_divrem) to improve its

Georg Brandlba83f822010-03-14 09:50:54 +00004988- Issue #4258: Make it possible to use base 2**30 instead of base 2**15 for the
4989 internal representation of integers, for performance reasons. Base 2**30 is
4990 enabled by default on 64-bit machines. Add --enable-big-digits option to
4991 configure, which overrides the default. Add sys.long_info structseq to
4992 provide information about the internal format.
Mark Dickinsonefc82f72009-03-20 15:51:55 +00004993
Benjamin Peterson6ffe8522009-03-18 20:52:15 +00004994- Issue #4034: Fix weird attribute error messages of the traceback object. (As a
4995 result traceback.__members__ no longer exists.)
4996
Georg Brandlba83f822010-03-14 09:50:54 +00004997- Issue #4474: PyUnicode_FromWideChar now converts characters outside the BMP to
4998 surrogate pairs, on systems with sizeof(wchar_t) == 4 and sizeof(Py_UNICODE)
4999 == 2.
Mark Dickinson6b265f12009-03-18 16:07:26 +00005000
Georg Brandlba83f822010-03-14 09:50:54 +00005001- Issue #5237: Allow auto-numbered fields in str.format(). For example: ``'{}
5002 {}'.format(1, 2) == '1 2'``.
Eric Smith6f42edb2009-03-14 11:57:26 +00005003
Georg Brandlba83f822010-03-14 09:50:54 +00005004- Issue #3652: Make the 'line' argument for ``warnings.showwarning()`` a
Brett Cannon6c4cff02009-03-11 04:51:06 +00005005 requirement. Means the DeprecationWarning from Python 2.6 can go away.
5006
Georg Brandlba83f822010-03-14 09:50:54 +00005007- Issue #5247: Improve error message when unknown format codes are used when
5008 using ``str.format()`` with str, unicode, long, int, and float arguments.
Eric Smithe9fb6862009-02-20 14:02:36 +00005009
Georg Brandlba83f822010-03-14 09:50:54 +00005010- Running Python with the -3 option now also warns about classic division for
5011 ints and longs.
Raymond Hettinger08259e82009-02-18 23:10:19 +00005012
Georg Brandlba83f822010-03-14 09:50:54 +00005013- Issue #5260: Long integers now consume less memory: average saving is 2 bytes
5014 per long on a 32-bit system and 6 bytes per long on a 64-bit system.
Mark Dickinson2ffb26f2009-02-15 10:13:41 +00005015
Antoine Pitrou76a4b892009-02-13 13:52:33 +00005016- Issue #5186: Reduce hash collisions for objects with no __hash__ method by
5017 rotating the object pointer by 4 bits to the right.
5018
Georg Brandlba83f822010-03-14 09:50:54 +00005019- Issue #4575: Fix Py_IS_INFINITY macro to work correctly on x87 FPUs: it now
5020 forces its argument to double before testing for infinity.
Mark Dickinsonc97c9092009-02-09 14:18:43 +00005021
Benjamin Petersone18ef192009-01-20 14:21:16 +00005022- Issue #4978: Passing keyword arguments as unicode strings is now allowed.
5023
Georg Brandl29c6a282009-04-05 20:23:13 +00005024- Issue #1242657: the __len__() and __length_hint__() calls in several tools
Raymond Hettingerb5163702009-02-02 21:50:13 +00005025 were suppressing all exceptions. These include list(), filter(), map(),
5026 zip(), and bytearray().
5027
Benjamin Peterson596d3062009-01-19 15:42:23 +00005028- os.ftruncate raises OSErrors instead of IOErrors for consistency with other os
5029 functions.
5030
Benjamin Peterson5848d1f2009-01-19 00:08:08 +00005031- Issue #4991: Passing invalid file descriptors to io.FileIO now raises an
5032 OSError.
5033

5035
Georg Brandlba83f822010-03-14 09:50:54 +00005036- Issue #4935: The overflow checking code in the expandtabs() method common to
5037 str, bytes and bytearray could be optimized away by the compiler, letting the
5038 interpreter segfault instead of raising an error.
Antoine Pitrouc2f02212009-01-13 23:13:52 +00005039
Amaury Forgeot d'Arca40d5732009-01-12 23:36:55 +00005040- Issue #3720: Fix a crash when an iterator modifies its class and removes its
5041 __next__ method.
5042

5046
Antoine Pitrou4c5ecb72009-01-09 21:40:55 +00005047- Issue #4074: Change the criteria for doing a full garbage collection (i.e.
5048 collecting the oldest generation) so that allocating lots of objects without
5049 destroying them does not show quadratic performance. Based on a proposal by
Benjamin Petersond50a5d52009-07-13 00:03:20 +00005050 Martin von Löwis at
Antoine Pitrou4c5ecb72009-01-09 21:40:55 +00005051 http://mail.python.org/pipermail/python-dev/2008-June/080579.html.

5054
Georg Brandlba83f822010-03-14 09:50:54 +00005055- Issue #1180193: When importing a module from a .pyc (or .pyo) file with an
5056 existing .py counterpart, override the co_filename attributes of all code
5057 objects if the original filename is obsolete (which can happen if the file has
5058 been renamed, moved, or if it is accessed through different paths). Patch by
5059 Ziga Seilnacht and Jean-Paul Calderone.
Antoine Pitroue96d4ea2009-01-06 18:10:47 +00005060
Georg Brandlba83f822010-03-14 09:50:54 +00005061- Issue #4075: Use ``OutputDebugStringW()`` in Py_FatalError.

Hirokazu Yamamoto99a1b202009-01-01 15:45:39 +00005063- Issue #4797: IOError.filename was not set when _fileio.FileIO failed to open
5064 file with `str' filename on Windows.
5065
Antoine Pitrouaa687902009-01-01 14:11:22 +00005066- Issue #3680: Reference cycles created through a dict, set or deque iterator
5067 did not get collected.
5068
Georg Brandlba83f822010-03-14 09:50:54 +00005069- Issue #4701: PyObject_Hash now implicitly calls PyType_Ready on types where
5070 the tp_hash and tp_dict slots are both NULL.
Nick Coghlan180e4002008-12-30 01:18:48 +00005071
Benjamin Peterson7af65562008-12-29 17:56:58 +00005072- Issue #4764: With io.open, IOError.filename is set when trying to open a
5073 directory on POSIX systems.
5074
Benjamin Petersonfe231b02008-12-29 17:47:42 +00005075- Issue #4764: IOError.filename is set when trying to open a directory on POSIX
5076 systems.
5077
Georg Brandl6425a2f2008-12-28 11:54:53 +00005078- Issue #4759: None is now allowed as the first argument of
Georg Brandlba83f822010-03-14 09:50:54 +00005079 ``bytearray.translate()``. It was always allowed for ``bytes.translate()``.
Georg Brandl6425a2f2008-12-28 11:54:53 +00005080
Skip Montanarof205c132008-12-23 03:30:15 +00005081- Added test case to ensure attempts to read from a file opened for writing
5082 fail.
5083
Georg Brandlba83f822010-03-14 09:50:54 +00005084- Issue #2467: gc.DEBUG_STATS reported invalid elapsed times. Also, always print
5085 elapsed times, not only when some objects are uncollectable/unreachable.
5086 Original patch by Neil Schemenauer.
Antoine Pitrou73c0e652008-12-17 22:46:54 +00005087

Georg Brandlba83f822010-03-14 09:50:54 +00005098- Issue #4445: Replace ``sizeof(PyStringObject)`` with
5099 ``offsetof(PyStringObject, ob_sval) + 1`` when allocating memory for str
5100 instances. On a typical machine this saves 3 bytes of memory (on average) per
5101 string allocation.
Mark Dickinson826f3fe2008-12-05 21:55:28 +00005102
Amaury Forgeot d'Arcdc619012008-11-22 20:01:18 +00005103- Issue #3996: On Windows, the PyOS_CheckStack function would cause the
5104 interpreter to abort ("Fatal Python error: Could not reset the stack!")
5105 instead of throwing a MemoryError.
5106
Georg Brandlba83f822010-03-14 09:50:54 +00005107- Issue #3689: The list reversed iterator now supports __length_hint__ instead
5108 of __len__. Behavior now matches other reversed iterators.
Raymond Hettinger7989a4d2008-12-03 15:42:10 +00005109
Benjamin Petersonc078f922008-11-21 22:27:24 +00005110- Issue #4367: Python would segfault during compiling when the unicodedata
5111 module couldn't be imported and \N escapes were present.
5112
Georg Brandlba83f822010-03-14 09:50:54 +00005113- Issue #4233: Changed semantic of ``_fileio.FileIO``'s ``close()`` method on
5114 file objects with closefd=False. The file descriptor is still kept open but
5115 the file object behaves like a closed file. The ``FileIO`` object also got a
5116 new readonly attribute ``closefd``.
Amaury Forgeot d'Arc32265652008-11-20 23:34:31 +00005117
Benjamin Peterson46cc6d12008-11-19 21:49:09 +00005118- Issue #4348: Some bytearray methods returned that didn't cause any change to
5119 the bytearray, returned the same bytearray instead of a copy.
5120
Georg Brandlba83f822010-03-14 09:50:54 +00005121- Issue #4317: Fixed a crash in the ``imageop.rgb2rgb8()`` function.

5124
Benjamin Peterson6624a9f2008-11-03 15:14:51 +00005125- Issue #4048: The parser module now correctly validates relative imports.
5126
Benjamin Petersondcee09d2008-10-31 02:16:05 +00005127- Issue #4225: ``from __future__ import unicode_literals`` didn't work in an

5134 __future__ import didn't work.
5135
Benjamin Peterson399b1fe2008-10-25 02:53:28 +00005136- Using ``nonlocal`` as a variable name will now raise a Py3k SyntaxWarning
Georg Brandl7fb00ad2008-10-25 07:00:52 +00005137 because it is a reserved word in 3.x.
Benjamin Peterson399b1fe2008-10-25 02:53:28 +00005138
Georg Brandlba83f822010-03-14 09:50:54 +00005139- On windows, ``os.chdir()`` given unicode was not working if
5140 GetCurrentDirectoryW returned a path longer than MAX_PATH. (But It's doubtful
5141 this code path is really executed because I cannot move to such directory on
5142 win2k)
Hirokazu Yamamoto10a018c2008-10-09 10:00:30 +00005143
Georg Brandlba83f822010-03-14 09:50:54 +00005144- Issue #4069: When ``set.remove(element)`` is used with a set element, the
5145 element is temporarily replaced with an equivalent frozenset. But the
5146 eventual KeyError would always report the empty ``frozenset()`` as the missing
5147 key. Now it correctly refers to the initial element.
Amaury Forgeot d'Arcd78b9dc2008-10-07 20:32:10 +00005148

6544-----------------
6545
Martin v. Löwis9fa5a282008-09-11 06:53:30 +00006546- Issue #3642: Suppress warning in obmalloc when size_t is larger than uint.
6547
Amaury Forgeot d'Arc05e34492008-09-10 22:04:45 +00006548- Issue #3743: In a few places, PY_FORMAT_SIZE_T was incorrectly used with
6549 PyString_FromFormat or PyErr_Format to display size_t values. The macro
6550 PY_FORMAT_SIZE_T is designed to select the correct format for the OS
6551 ``printf`` function, whereas PyString_FromFormat has an independent
6552 implementation and uses "%zd" on all platforms for size_t values.
6553 This makes a difference on win64, where ``printf`` needs "%Id" to display
6554 64bit values.
6555
Benjamin Peterson97179b02008-09-09 20:55:01 +00006556- Issue #3634: _weakref.ref(Exception).__init__() gave invalid return value on
6557 error.
6558
Amaury Forgeot d'Arcd3ffb892008-09-09 07:24:30 +00006559- Issue #3777: long() applied to a float object now always return a long
6560 object; previously an int would be returned for small values. the __long__
6561 method is allowed to return either an int or a long, but the behaviour of
6562 float objects should not change to respect backward compatibility.
6563
Amaury Forgeot d'Arc3571fbf2008-09-01 19:52:00 +00006564- Issue #3751: str.rpartition would perform a left-partition when called with
6565 a unicode argument.
6566
Benjamin Peterson17f03ca2008-09-01 14:18:30 +00006567- Issue #3683: Fix compilation when --without-threads is given.
6568
Antoine Pitroud4ae97b2008-08-29 18:39:48 +00006569- Issue #3668: Fix a memory leak with the "s*" argument parser in
Vinay Sajip35e3b032008-09-01 14:33:59 +00006570 PyArg_ParseTuple and friends, which occurred when the argument for "s*"
Antoine Pitroud4ae97b2008-08-29 18:39:48 +00006571 was correctly parsed but parsing of subsequent arguments failed.
6572
Vinay Sajip35e3b032008-09-01 14:33:59 +00006573- Issue #2534: speed up isinstance() and issubclass() by 50-70%, so as to
Antoine Pitrou0668c622008-08-26 22:42:08 +00006574 match Python 2.5 speed despite the __instancecheck__ / __subclasscheck__
6575 mechanism. In the process, fix a bug where isinstance() and issubclass(),
6576 when given a tuple of classes as second argument, were looking up
6577 __instancecheck__ / __subclasscheck__ on the tuple rather than on each
6578 type object.
6579
Neal Norwitz18aa3882008-08-24 05:04:52 +00006580- Fix crashes on memory allocation failure found with failmalloc.
6581
6582- Fix memory leaks found with valgrind and update suppressions file.
6583
6584- Fix compiler warnings in opt mode which would lead to invalid memory reads.
6585
6586- Fix problem using wrong name in decimal module reported by pychecker.
6587
Christian Heimes7d4c3172008-08-22 19:47:25 +00006588- Silenced another compiler warning about a used but not defined
6589 function 'stringlib_contains_obj'.
6590
Benjamin Peterson712ee922008-08-24 18:10:20 +00006591- Added warnings on the use of ``__getslice__``, ``__setslice__``, or
6592 ``__delslice__``.
6593
Gregory P. Smith2bb25cc2008-09-02 05:29:51 +00006594- Issue #3678: Correctly pass LDFLAGS and LDLAST to the linker on shared
6595 library targets in the Makefile.
6596
Gregory P. Smith980b99b2008-09-07 05:15:18 +00006597- Issue #1204: The configure script now tests for additional libraries
6598 that may be required when linking against readline. This fixes issues
6599 with x86_64 builds on some platforms (a few Linux flavors and OpenBSD).

Amaury Forgeot d'Arc24cb3822008-09-11 20:56:13 +00006609- Issue #3640: Pickling a list or a dict uses less local variables, to reduce
6610 stack usage in the case of deeply nested objects.
6611

Nick Coghland2e09382008-09-11 12:11:06 +00006622- Issue #3781: Clean up the API for warnings.catch_warnings() by having it
Brett Cannon672237d2008-09-09 00:49:16 +00006623 return a list or None rather than a custom object.
6624
Benjamin Peterson6ac7d7c2008-09-06 19:28:11 +00006625- Issue #1638033: Cookie.Morsel gained the httponly attribute.
6626
Antoine Pitrouebcd0ce2008-09-05 23:30:23 +00006627- Issue #3535: zipfile couldn't read some zip files larger than 2GB.

Brett Cannon1eaf0742008-09-02 01:25:16 +00006649 warnings.catch_warnings() along with some API cleanup. Expanding the tests
6650 for catch_warnings() also led to an improvement in the raising of a
6651 DeprecationWarning related to warnings.warn_explicit().
6652
Benjamin Peterson973e6c22008-09-01 23:12:58 +00006653- The deprecation warnings for the old camelCase threading API were removed.

6675
Amaury Forgeot d'Arc293924b2008-09-02 23:19:56 +00006676- Issue #2975: When compiling several extension modules with Visual Studio 2008
6677 from the same python interpreter, some environment variables would grow
6678 without limit.
6679
Benjamin Peterson37346b22008-08-23 20:27:43 +00006680- Issue #3643: Added a few more checks to _testcapi to prevent segfaults by
6681 exploitation of poor argument checking.
6682
Gerhard Häringef2276b2008-09-12 13:54:06 +00006683- sqlite3: Changed docstring of iterdump() to mark method as "Non-standard".

6696 wrapper for warnings.catch_warnings() that makes it easier to check
6697 that expected warning messages are being reported.
6698

Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00006717What's New in Python 2.6 beta 3?
6718================================

Barry Warsaw07a4a382008-08-21 01:15:08 +00006720*Release date: 20-Aug-2008*
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00006721
6722Core and Builtins
6723-----------------
6724
Guido van Rossumf8402962008-08-20 15:01:50 +00006725- Issue #1878: Remove Py_TPFLAGS_HAVE_VERSION_TAG from
6726 Py_TPFLAGS_DEFAULT when not building the core. This means 3rd party
6727 extensions do not automatically benefit from the class attribute
6728 cache; they will have to explicitly add Py_TPFLAGS_HAVE_VERSION_TAG
6729 to their tp_flags field if they care. This is a backwards
6730 compatibility feature; in 3.0, all types will use the cache by
6731 default.
6732
Benjamin Petersonf647dc12008-08-20 01:27:30 +00006733- Keyword arguments can now follow starred arguments. (``f(a, *args,
6734 keyword=23)`` is now valid syntax.)
6735
Thomas Heller0ad5ae02008-08-19 19:25:04 +00006736- ctypes function pointers that are COM methods have a boolean True
6737 value again.
6738
Martin v. Löwisf91d46a2008-08-12 14:49:50 +00006739- Issue #3139: Make buffer-interface thread-safe wrt. PyArg_ParseTuple,
6740 by denying s# to parse objects that have a releasebuffer procedure,
6741 and introducing s*.
6742
Georg Brandl1e13ea92008-08-11 09:07:59 +00006743- Issue #3537: Fix an assertion failure when an empty but presized dict
6744 object was stored in the freelist.
6745
Mark Dickinsonb6467572008-08-04 21:30:09 +00006746- Issue #1481296: Make long(float('nan')) and int(float('nan')) raise
6747 ValueError consistently across platforms.
6748
Amaury Forgeot d'Arc39fd6722008-07-31 21:28:03 +00006749- Issue #3479: On platforms where sizeof(int) is smaller than sizeof(long)
6750 (64bit Unix, for example), unichr() would truncate its argument and return
6751 u'\x00' for unichr(2**32). Now it properly raises an OverflowError.
6752
Neal Norwitze7d8be82008-07-31 17:17:14 +00006753- Apply security patches from Apple.
6754
Amaury Forgeot d'Arc246daed2008-07-31 00:42:16 +00006755- Issue #2542: Now that issubclass() may call arbitrary code, ensure that
6756 PyErr_ExceptionMatches returns 0 when an exception occurs there.
6757
Antoine Pitrou92f82162008-07-25 22:22:08 +00006758- Issue #1819: function calls with several named parameters are now on
6759 average 35% faster (as measured by pybench).
6760
Amaury Forgeot d'Arce4921fe2008-07-21 22:00:38 +00006761- Issue #2378: An unexpected UnboundLocalError or NameError could appear when
6762 the python debugger steps into a class statement: the free variables (local
6763 variables defined in an outer scope) would be deleted from the outer scope.
6764
Gregory P. Smith0470bab2008-07-22 04:46:32 +00006765- Issue #2620: Overflow checking when allocating or reallocating memory
6766 was not always being done properly in some python types and extension
6767 modules. PyMem_MALLOC, PyMem_REALLOC, PyMem_NEW and PyMem_RESIZE have
6768 all been updated to perform better checks and places in the code that
6769 would previously leak memory on the error path when such an allocation
6770 failed have been fixed.

6773-------
6774
Hirokazu Yamamoto838c79f2008-08-20 13:14:07 +00006775- Issue #3612: Added some missing basic types in ctypes.wintypes.
6776
Benjamin Petersone977ad42008-08-20 01:42:01 +00006777- The methods ``is_in_tuple()``, ``is_vararg()``, and ``is_keywordarg()`` of
6778 symtable.Symbol have been deprecated for removal in 3.0 and the next release.
6779
Amaury Forgeot d'Arc351ffb82008-08-18 19:23:47 +00006780- Issue #2234: distutils failed for some versions of the cygwin compiler. The
6781 version reported by these tools does not necessarily follow the python
6782 version numbering scheme, so the module is less strict when parsing it.
6783
Nick Coghlanf70385a2008-08-18 12:42:46 +00006784- Issue #2235: Added Py3k warnings for types which will become unhashable
6785 under the stricter __hash__ inheritance rules in 3.0. Several types
6786 which did not meet the rules for hash invariants and were already
6787 unhashable in 3.0 have now been explicitly flagged as unhashable in
6788 2.6 as well (collections.Mapping, collections.Set, unittest.TestSuite,
6789 xml.dom.minidom.NamedNodeMap, numbers.Number, UserList.UserList)
6790
Brett Cannon88f801d2008-08-18 00:46:22 +00006791- Update __all__ for cookielib, csv, os, urllib2, and weakref to include things
6792 imported into the module but exposed as part of the module's API.
6793
Brett Cannon7b96f072008-08-18 00:41:11 +00006794- Remove an unneeded import of abc.ABCMeta from 'inspect'.

6799
Hirokazu Yamamoto41a81eb2008-08-17 13:10:46 +00006800- Issue #3575: Incremental decoder's decode function now takes bytearray
6801 by using 's*' instead of 't#'.
6802
Mark Dickinson3e4caeb2009-02-21 20:27:01 +00006803- Issue #2222: Fixed reference leak when occurred os.rename()
Hirokazu Yamamoto7f30a682008-08-17 09:46:56 +00006804 fails unicode conversion on 2nd parameter. (windows only)
6805
Georg Brandl222e2082010-08-01 22:27:39 +00006806- Issue #2464: urllib2 now supports a malformation in the URL received
Facundo Batista94f243a2008-08-17 03:38:39 +00006807 in a redirect.
6808
Brett Cannonabe423e2008-08-16 21:47:07 +00006809- Silence the DeprecationWarning raised when importing mimetools in
Brett Cannon721b1452008-08-16 22:00:27 +00006810 BaseHTTPServer, cgi (and rfc822), httplib.
Brett Cannonabe423e2008-08-16 21:47:07 +00006811
Facundo Batistaeb90b782008-08-16 14:44:07 +00006812- Issue #2776: fixed small issue when handling an URL with double slash
6813 after a 302 response in the case of not going through a proxy.
6814
Antoine Pitroub90a8be2008-08-15 21:03:21 +00006815- Issue #2676: in the email package, content-type parsing was hanging on
6816 pathological input because of quadratic or exponential behaviour of a
6817 regular expression.
6818
Antoine Pitrou11ec65d2008-08-14 21:04:30 +00006819- Issue #3476: binary buffered reading through the new "io" library is now
6820 thread-safe.
6821
Brett Cannonbf3157b2008-08-14 05:00:03 +00006822- Silence the DeprecationWarning of rfc822 when it is imported by mimetools
6823 since mimetools itself is deprecated. Because modules are cached, all
6824 subsequent imports of rfc822 will not raise a visible DeprecationWarning.
6825

6904
Nick Coghlan2a0c2b12008-08-04 12:47:17 +00006905- Issue #643841: The language reference now provides more detailed

6918
Georg Brandl3e483f62008-07-16 22:57:41 +00006919- Issue #3156: Fix inconsistent behavior of the bytearray type: all
6920 its methods now allow for items objects that can be converted to
6921 an integer using operator.index().
6922
Mark Dickinson64b7e502008-07-16 09:40:03 +00006923- Issue #3360: Fix incorrect parsing of '020000000000.0', which
6924 produced a ValueError instead of giving the correct float.
6925
Eric Smitha5fa5a22008-07-16 00:11:49 +00006926- Issue #3083: Add alternate (#) formatting for bin, oct, hex output

6928
Mark Dickinson7103aa42008-07-15 19:08:33 +00006929- Issue #3008: the float type has a new instance method 'float.hex'
6930 and a new class method 'float.fromhex' to convert floating-point
6931 numbers to and from hexadecimal strings, respectively.
6932
Nick Coghlan6d6bd442008-07-15 15:40:22 +00006933- Issue #2235: __hash__ is once again inherited by default. To allow
6934 collections.Hashable to remain meaningful in the presence of the
6935 default hash implementation (object.__hash__), it is now possible
6936 to explicit block inheritance of hash by setting __hash__=None at
6937 the Python level, or tp_hash=PyObject_HashNotImplemented at the C
6938 level.
6939
Nick Coghlanb028f502008-07-13 14:52:36 +00006940- Issue #3221: Issue a RuntimeWarning instead of raising SystemError if
6941 the parent module cannot be found while performing an absolute import.
6942 This means that an incorrectly defined __package__ attribute will
6943 now only prevent relative imports in that module rather than causing
6944 all imports from that module to fail.
6945
Nick Coghlan14ff9942008-07-08 14:21:42 +00006946- Issue #2517: Allow unicode messages in Exceptions again by correctly

6956 another thread's dictionary.
6957
Mark Dickinson1ec2fcd2008-06-20 14:53:43 +00006958- Issue #3004: Minor change to slice.indices(): the start and stop
6959 arguments are now treated identically, making the behaviour easier
6960 to describe and understand. For example, slice(None, -10,
6961 1).indices(9) now returns (0, 0, 1) instead of (0, -1, 1), and
6962 slice(None, 10, -1).indices(10) returns (9, 9, -1) instead of (9,
6963 10, -1).

Georg Brandl278fc502008-07-19 12:46:12 +00006965- Issue #3219: Calling a function with repeated keyword arguments,

6967 from 2.4 caused by the switch to the new compiler.

7006 both unnecessary (HTTP allows text content to be sent in several forms) and
Andrew M. Kuchlingcc3f2b12008-07-10 14:43:31 +00007007 wrong because the actual transmitted size could differ from the
Amaury Forgeot d'Arc0f7cddc2008-07-06 21:34:39 +00007008 content-length. The problem had been corrected in the 2.4 branch, but never

Benjamin Peterson23681932008-05-12 21:42:13 +00007392
Vinay Sajip9828b7e2008-06-17 11:04:02 +00007393- Library: on MacOS X you can now set ``ARCHFLAGS`` in the shell
Ronald Oussoren5640ce22008-06-05 12:58:24 +00007394 environment to control the '-arch' flags that are used to build
7395 an extension. This was added for compatibility with Apple's build
7396 of Python.
7397
7398- The bundled OSX-specific copy of libbffi is now in sync with the version
7399 shipped with PyObjC 2.0 and includes support for x86_64 and ppc64 platforms.
7400
Georg Brandl25c34082008-08-18 23:09:49 +00007401- The threading module gained aliases for names that will be removed in the
7402 3.x series.

7410
Brett Cannonb61d8012008-05-11 23:39:04 +00007411- ``Lib/lib-old`` is now added to sys.path.
7412
Ronald Oussoren5640ce22008-06-05 12:58:24 +00007413- On MacOS X it is now possible to install the framework in 64-bit
7414 mode or even as a 4-way universal binary (that is, PPC, i386,
Georg Brandl5cc774e2008-06-11 20:28:06 +00007415 PPC64 and x86_64 support in one binary).
Ronald Oussoren5640ce22008-06-05 12:58:24 +00007416
7417 This is controlled by the configure argument ``--with-universal-archs``:
7418
7419 - ``--with-universal-archs=all``: install 4-way universal
7420
7421 - ``--with-universal-archs=32-bit``: install 2-way universal, 32-bit (the default)
7422
7423 - ``--with-universal-archs=64-bit``: install 2-way universal, 64-bit
7424
7425 This option should be used in combination with ``--enable-universalsdk=``.
7426
7427 NOTE: 64-bit and 4-way builds are only suppported on Mac OS X 10.5 (or later).

Christian Heimes7a990612008-05-26 13:15:11 +00007435
7436- The PyString functions have been renamed to PyBytes. A batch of
7437 defines were added so that the linker still sees the original
7438 PyString names.

Georg Brandl3ee81df2008-05-17 18:14:43 +00007476- Issue #1631171: Re-implement the 'warnings' module in C (the
7477 original Python code has been kept as backup). This will allow for
7478 using the 'warning's machinery in such places as the parser where
7479 use of pure Python code is not possible. Both the ``showarning()``
7480 and ``formatwarning()`` gain an optional 'line' argument which is
7481 not called by default for backwards-compatibility reasons. Setting
7482 ``warnings.showwarning()`` to an implementation that lacks support
7483 for the ``line`` argument will raise a DeprecationWarning.

Gregory P. Smithd59fefb2008-04-22 08:11:33 +00007508- The getpass module has been improved on Unix. It now uses /dev/tty
7509 by default and uses stderr instead of stdout. A GetPassWarning is
7510 issued when input echo cannot be controlled.

Georg Brandl3ee81df2008-05-17 18:14:43 +00007525- Issue #2513: distutils on Windows is now capable of cross-compiling
Mark Hammond495cf992008-04-07 01:53:39 +00007526 extension modules between 32 and 64 bit platforms. See the distutls

Georg Brandl3ee81df2008-05-17 18:14:43 +00007546- Issue #2550: The approach used by client/server code for obtaining
7547 ports to listen on in network-oriented tests has been refined in an
7548 effort to facilitate running multiple instances of the entire
7549 regression test suite in parallel without issue.
7550 test_support.bind_port() has been fixed such that it will always
7551 return a unique port -- which wasn't always the case with the
7552 previous implementation, especially if socket options had been set
7553 that affected address reuse (i.e. SO_REUSEADDR, SO_REUSEPORT). The
7554 new implementation of bind_port() will actually raise an exception
7555 if it is passed an AF_INET/SOCK_STREAM socket with either the
7556 SO_REUSEADDR or SO_REUSEPORT socket option set. Furthermore, if
7557 available, bind_port() will set the SO_EXCLUSIVEADDRUSE option on
7558 the socket it's been passed. This currently only applies to
7559 Windows. This option prevents any other sockets from binding to the
7560 host/port we've bound to, thus removing the possibility of the
7561 'non-deterministic' behaviour, as Microsoft puts it, that occurs
7562 when a second SOCK_STREAM socket binds and accepts to a host/port
7563 that's already been bound by another socket. The optional preferred
7564 port parameter to bind_port() has been removed. Under no
7565 circumstances should tests be hard coding ports!
7566
7567 test_support.find_unused_port() has also been introduced, which will
7568 pass a temporary socket object to bind_port() in order to obtain an
7569 unused port. The temporary socket object is then closed and
7570 deleted, and the port is returned. This method should only be used
7571 for obtaining an unused port in order to pass to an external program
7572 (i.e. the -accept [port] argument to openssl's s_server mode) or as
7573 a parameter to a server-oriented class that doesn't give you direct
7574 access to the underlying socket used.
7575
7576 Finally, test_support.HOST has been introduced, which should be used
7577 for the host argument of any relevant socket calls (i.e. bind and
7578 connect).
Trent Nelsone41b0062008-04-08 23:47:30 +00007579
7580 The following tests were updated to following the new conventions:
Georg Brandl3ee81df2008-05-17 18:14:43 +00007581 test_socket, test_smtplib, test_asyncore, test_ssl, test_httplib,
Trent Nelsone41b0062008-04-08 23:47:30 +00007582 test_poplib, test_ftplib, test_telnetlib, test_socketserver,
7583 test_asynchat and test_socket_ssl.
7584
Georg Brandl3ee81df2008-05-17 18:14:43 +00007585 It is now possible for multiple instances of the regression test
7586 suite to run in parallel without issue.

Eric Smitha73fbe72008-02-23 03:09:44 +00007865- Added the future_builtins module, which contains hex() and oct().
7866 These are the PEP 3127 version of these functions, designed to be
7867 compatible with the hex() and oct() builtins from Python 3.0. They
7868 differ slightly in their output formats from the existing, unchanged
7869 Python 2.6 builtins. The expected usage of the future_builtins
7870 module is:
7871 from future_builtins import hex, oct
7872
Eric Smith7ef40bf2008-02-20 23:34:22 +00007873- Issue #1600: Modifed PyOS_ascii_formatd to use at most 2 digit
7874 exponents for exponents with absolute value < 100. Follows C99
7875 standard. This is a change on Windows, which would use 3 digits.
7876 Also, added 'n' to the formats that PyOS_ascii_formatd understands,
7877 so that any alterations it does to the resulting string will be
7878 available in stringlib/formatter.h (for float.__format__).
7879
Eric Smith5a3c1352008-02-19 13:21:56 +00007880- Implemented PEP 3101, Advanced String Formatting. This adds a new
7881 builtin format(); a format() method for str and unicode; a
7882 __format__() method to object, str, unicode, int, long, float, and
7883 datetime; the class string.Formatter; and the C API
7884 PyObject_Format().
7885
Georg Brandl3ee81df2008-05-17 18:14:43 +00007886- Fixed several potential crashes, all caused by specially crafted
7887 __del__ methods exploiting objects in temporarily inconsistent
7888 state.

Vinay Sajipb7edfc42008-04-02 21:10:23 +00007890- Issue #2115: Important speedup in setting __slot__ attributes. Also
Georg Brandl3ee81df2008-05-17 18:14:43 +00007891 prevent a possible crash: an Abstract Base Class would try to access
7892 a slot on a registered virtual subclass.

7898 in order to allow pymalloc to free more arenas. Python may give back
7899 memory to the OS earlier.
Christian Heimes3b718a72008-02-14 12:47:33 +00007900
Georg Brandl3ee81df2008-05-17 18:14:43 +00007901- Issue #2045: Fix an infinite recursion triggered when printing a
7902 subclass of collections.defaultdict, if its default_factory is set
7903 to a bound method.
Amaury Forgeot d'Arcb01aa432008-02-08 00:56:02 +00007904
Christian Heimesf75dbef2008-02-08 00:11:31 +00007905- Fixed a minor memory leak in dictobject.c. The content of the free
7906 list was not freed on interpreter shutdown.
7907
Georg Brandl21e99f42010-03-07 15:23:59 +00007908- Limit free list of method and built-in function objects to 256
Georg Brandl3ee81df2008-05-17 18:14:43 +00007909 entries each.
Christian Heimes6075a822008-02-06 12:44:34 +00007910
Georg Brandl3ee81df2008-05-17 18:14:43 +00007911- Patch #1953: Added ``sys._compact_freelists()`` and the C API
7912 functions ``PyInt_CompactFreeList`` and ``PyFloat_CompactFreeList``
Christian Heimes422051a2008-02-04 18:00:12 +00007913 to compact the internal free lists of pre-allocted ints and floats.
7914
Georg Brandl3ee81df2008-05-17 18:14:43 +00007915- Issue #1983: Fixed return type of fork(), fork1() and forkpty()
7916 calls. Python expected the return type int but the fork familie
7917 returns pi_t.
Christian Heimes951cc0f2008-01-31 23:08:23 +00007918
Georg Brandl3ee81df2008-05-17 18:14:43 +00007919- Issue #1678380: Fix a bug that identifies 0j and -0j when they
7920 appear in the same code unit.
Mark Dickinson105be772008-01-31 22:17:37 +00007921
Georg Brandl3ee81df2008-05-17 18:14:43 +00007922- Issue #2025: Add tuple.count() and tuple.index() methods to comply
7923 with the collections.Sequence API.
Raymond Hettinger5b07ebc2008-02-07 00:54:20 +00007924

Georg Brandl3ee81df2008-05-17 18:14:43 +00007928- Added ``PyType_ClearCache()`` and ``sys._clear_type_cache`` to clear
7929 the internal lookup cache for ref leak tests.
Christian Heimes908caac2008-01-27 23:34:59 +00007930
Georg Brandl3ee81df2008-05-17 18:14:43 +00007931- Patch #1473257: generator objects gain a gi_code attribute. This is
7932 the same object as the func_code attribute of the function that
7933 produced the generator.
Georg Brandl0cdf9a32008-01-26 14:14:20 +00007934
Georg Brandl3ee81df2008-05-17 18:14:43 +00007935- Issue #1920: "while 0" statements were completely removed by the
7936 compiler, even in the presence of an "else" clause, which is
7937 supposed to be run when the condition is false. Now the compiler
7938 correctly emits bytecode for the "else" suite.
Amaury Forgeot d'Arc31eaafe2008-01-24 22:59:25 +00007939
Guido van Rossumeead05f2008-01-24 18:21:02 +00007940- A few crashers fixed: weakref_in_del.py (issue #1377858);
7941 loosing_dict_ref.py (issue #1303614, test67.py);
7942 borrowed_ref_[34].py (not in tracker).
7943
Vinay Sajipd7cf32e2008-01-24 12:43:33 +00007944- Issue #1069410: The "can't load dll" message box on Windows is
Christian Heimesb2302ba2008-01-23 17:15:06 +00007945 suppressed while an extension is loaded by calling SetErrorMode in
7946 dynload_win.c. The error is still reported properly.
7947
Georg Brandl3ee81df2008-05-17 18:14:43 +00007948- Issue #1915: Python compiles with --enable-unicode=no again. However
Christian Heimes082c9b02008-01-23 14:20:50 +00007949 several extension methods and modules do not work without unicode
7950 support.
7951
Georg Brandl26543b12008-01-21 18:36:51 +00007952- Issue #1882: when compiling code from a string, encoding cookies in the
7953 second line of code were not always recognized correctly.
7954
Georg Brandl14404b62008-01-19 19:27:05 +00007955- Issue #1679: "0x" was taken as a valid integer literal.
7956
Georg Brandl6caad7d2008-01-26 14:19:22 +00007957- Issue #1865: ``bytes`` as an alias for ``str`` and b"" as an alias "" were
Christian Heimes288e89a2008-01-18 18:24:07 +00007958 added.
7959
Christian Heimesc94e2b52008-01-14 04:13:37 +00007960- sys.float_info / PyFloat_GetInfo: The floating point information
7961 object was converted from a dict to a specialized structseq object.
7962
Georg Brandl3ee81df2008-05-17 18:14:43 +00007963- Patch #1816: Added sys.flags structseq. It exposes the status of
7964 most command line arguments and PYTHON* environment variables.
Christian Heimesf31b69f2008-01-14 03:42:48 +00007965
Georg Brandl3ee81df2008-05-17 18:14:43 +00007966- Objects/structseq.c: Implemented new structseq representation. The
7967 patch makes structseqs (e.g. the return value of os.stat) more
7968 readable.
Christian Heimes9c201962008-01-14 03:33:52 +00007969
Georg Brandl3ee81df2008-05-17 18:14:43 +00007970- Patch #1700288: added a type attribute cache that caches method
7971 accesses, resulting in speedups in heavily object-oriented code.
Amaury Forgeot d'Arce4c270c2008-01-14 00:29:41 +00007972
Neal Norwitz3fc15b82008-01-10 05:42:58 +00007973- Bug #1776: __import__() no longer accepts filenames on any platform.
7974 The first parameter to __import__() must be a valid module name.
Christian Heimes3403f152008-01-09 19:56:33 +00007975
Georg Brandlaed6c662008-01-07 17:25:53 +00007976- Patch #1668: renamed THREADDEBUG envvar to PYTHONTHREADDEBUG.
7977
Georg Brandl3ee81df2008-05-17 18:14:43 +00007978- Patch #602345: Add -B command line option, PYTHONDONTWRITEBYTECODE
7979 envvar and sys.dont_write_bytecode attribute. All these can be set
7980 to forbid Python to attempt to write compiled bytecode files.
Georg Brandl2da0fce2008-01-07 17:09:35 +00007981
Georg Brandl3ee81df2008-05-17 18:14:43 +00007982- Improve some exception messages when Windows fails to load an
7983 extension module. Now we get for example '%1 is not a valid Win32
7984 application' instead of 'error code 193'.

7989 y) functions.
Christian Heimese2ca4242008-01-03 20:23:15 +00007990
Christian Heimes0a8143f2007-12-18 23:22:54 +00007991- Issue #1635: Platform independent creation and representation of NaN
Georg Brandl3ee81df2008-05-17 18:14:43 +00007992 and INF. float("nan"), float("inf") and float("-inf") now work on
7993 every platform with IEEE 754 semantics.
Christian Heimes0a8143f2007-12-18 23:22:54 +00007994
Georg Brandl3ee81df2008-05-17 18:14:43 +00007995- Compiler now generates simpler and faster code for dictionary
7996 literals. The oparg for BUILD_MAP now indicates an estimated
7997 dictionary size. There is a new opcode, STORE_MAP, for adding
7998 entries to the dictionary.

Georg Brandl3ee81df2008-05-17 18:14:43 +00008027- Patch #1739468: Directories and zipfiles containing a __main__.py
8028 file can now be directly executed by passing their name to the
8029 interpreter. The directory/zipfile is automatically inserted as the
8030 first entry in sys.path.

Georg Brandl3ee81df2008-05-17 18:14:43 +00008032- Issue #1265: Fix a problem with sys.settrace, if the tracing
8033 function uses a generator expression when at the same time the
8034 executed code is closing a paused generator.
Amaury Forgeot d'Arc0d75f092007-11-13 21:54:28 +00008035
Raymond Hettinger1760c8a2007-11-08 02:52:43 +00008036- sets and frozensets now have an isdisjoint() method.
8037
Raymond Hettinger3f8caa32007-10-24 01:28:33 +00008038- optimize the performance of builtin.sum().
8039

8041
Georg Brandl21e99f42010-03-07 15:23:59 +00008042- The enumerate() built-in function is no longer bounded to sequences
Georg Brandl3ee81df2008-05-17 18:14:43 +00008043 smaller than LONG_MAX. Formerly, it raised an OverflowError. Now,
8044 automatically shifts from ints to longs.
Raymond Hettinger8f669372007-10-03 21:18:11 +00008045
Georg Brandl3ee81df2008-05-17 18:14:43 +00008046- Issue #1686386: Tuple's tp_repr did not take into account the
8047 possibility of having a self-referential tuple, which is possible
8048 from C code. Nor did object's tp_str consider that a type's tp_str
8049 could do something that could lead to an inifinite recursion.
8050 Py_ReprEnter() and Py_EnterRecursiveCall(), respectively, fixed the
8051 issues.
Brett Cannon0b14f242007-09-30 19:45:10 +00008052
Georg Brandl3ee81df2008-05-17 18:14:43 +00008053- Issue #1164: It was possible to trigger deadlock when using the
8054 'print' statement to write to a file since the GIL was not released
8055 as needed. Now PyObject_Print() does the right thing along with
8056 various tp_print implementations of the built-in types and those in
8057 the collections module.
Brett Cannon01531592007-09-17 03:28:34 +00008058
Georg Brandl3ee81df2008-05-17 18:14:43 +00008059- Issue #1147: Exceptions were directly allowing string exceptions in
8060 their throw() method even though string exceptions no longer
8061 allowed.

Georg Brandl3ee81df2008-05-17 18:14:43 +00008063- Issue #1096: Prevent a segfault from getting the repr of a very
8064 deeply nested list by using the recursion counter.
Brett Cannona0c05512007-09-10 21:38:27 +00008065
Brett Cannon1e534b52007-09-07 04:18:30 +00008066- Issue #1202533: Fix infinite recursion calls triggered by calls to
Georg Brandl3ee81df2008-05-17 18:14:43 +00008067 PyObject_Call() never calling back out to Python code to trigger
8068 recursion depth updates/checks. Required the creation of a static
8069 RuntimeError instance in case normalizing an exception put the
8070 recursion check value past its limit. Fixes crashers
8071 infinite_rec_(1|2|4|5).py.
Brett Cannon1e534b52007-09-07 04:18:30 +00008072

Neal Norwitz0ac60192007-05-27 04:08:54 +00008086- Add new attribute names for function objects. All the func_* become
Georg Brandl3ee81df2008-05-17 18:14:43 +00008087 __*__ attributes. (Some already existed, e.g., __doc__ and
8088 __name__.)

Neal Norwitz8b2bfbc2007-05-23 06:35:32 +00008090- Add -3 option to the interpreter to warn about features that are
8091 deprecated and will be changed/removed in Python 3.0.
8092
Georg Brandl2134e752007-05-21 20:34:16 +00008093- Patch #1686487: you can now pass any mapping after '**' in function
8094 calls.
8095
Collin Winter62903052007-05-18 23:11:24 +00008096- except clauses may now be spelled either "except E, target:" or
Georg Brandl3ee81df2008-05-17 18:14:43 +00008097 "except E as target:". This is to provide forwards compatibility
8098 with Python 3.0.

Vinay Sajip8549ce32007-05-06 17:53:37 +00008105- When __slots__ are set to a unicode string, make it work the same as
Neal Norwitzcbd9ee62007-04-14 05:25:50 +00008106 setting a plain string, ie don't expand to single letter identifiers.
8107
Raymond Hettinger13936692007-04-11 18:40:58 +00008108- Request #1191699: Slices can now be pickled.
8109
Raymond Hettinger4db5fe92007-04-12 04:10:00 +00008110- Request #1193128: str.translate() now allows a None argument for
8111 translations that only remove characters without re-mapping the
8112 remaining characters.
8113
Georg Brandl5cb76c12007-03-21 09:00:39 +00008114- Patch #1682205: a TypeError while unpacking an iterable is no longer
8115 masked by a generic one with the message "unpack non-sequence".
8116
Neal Norwitzaa754b72007-03-21 06:39:48 +00008117- Remove unused file Python/fmod.c.
8118
Guido van Rossum143b5642007-03-23 04:58:42 +00008119- Bug #1683368: The object.__init__() and object.__new__() methods are
8120 now stricter in rejecting excess arguments. The only time when
8121 either allows excess arguments is when it is not overridden and the
8122 other one is. For backwards compatibility, when both are
8123 overridden, it is a deprecation warning (for now; maybe a Py3k
Guido van Rossum234b1ff2007-03-23 19:39:01 +00008124 warning later). Also, type.__init__() insists on the same signature
8125 as supported by type.__new__().

Georg Brandl3ee81df2008-05-17 18:14:43 +00008127- Patch #1675423: PyComplex_AsCComplex() now tries to convert an
8128 object to complex using its __complex__() method before falling back
8129 to the __float__() method. Therefore, the functions in the cmath
8130 module now can operate on objects that define a __complex__()
8131 method.

Georg Brandl3ee81df2008-05-17 18:14:43 +00009198 time so that opening a database previously created with the DB_DUP
9199 or DB_DUPSORT flag set will keep the proper behavior on subsequent
9200 opens. Specifically: dictionary assignment to a DB object will
9201 replace all values for a given key when the database allows
9202 duplicate values. DB users should use DB.put(k, v) when they want
9203 to store duplicates; not DB[k] = v.

9212 behavior of quoting dots if they are the second character of any
9213 line.
