1168
1169- As of 2.7.8, the 32-bit-only installer will support OS X 10.5
1170 and later systems as is currently done for Python 3.x installers.
1171 For 2.7.7 only, we will provide three installers:
1172 the legacy deprecated 10.3+ 32-bit-only format;
1173 the newer 10.5+ 32-bit-only format;
1174 and the unchanged 10.6+ 64-/32-bit format.
1175 Although binary installers will no longer be available from
1176 python.org as of 2.7.8, it will still be possible to build from
1177 source on 10.3.9 and 10.4 systems if necessary.
1178 See Mac/BuildScript/README.txt for more information.

2560 32-bit-only installer Pythons on systems with Xcode 4 (currently
2561 OS X 10.8, 10.7, and optionally 10.6).
2562 * Backport 3.3.0 fixes to 2.7 branch (for release in 2.7.4)
2563 * Since Xcode 4 removes ppc support, extension module builds now
2564 check for ppc compiler support and by default remove ppc and
2565 ppc64 archs when they are not available.
2566 * Extension module builds now revert to using system installed
2567 headers and libs (/usr and /System/Library) if the SDK used
2568 to build the interpreter is not installed or has moved.
2569 * Try to avoid building extension modules with deprecated
2570 and problematic Apple llvm-gcc compiler. If original compiler
2571 is not available, use clang instead by default.

Florent Xiclunac2279652012-02-12 14:49:03 +01003008- Issue #13994: Earlier partial revert of Distutils enhancements in 2.7
Ned Deilyc47a4592012-02-11 20:40:24 +01003009 has left two versions of customize_compiler, the original in
3010 distutils.sysconfig and another copy in distutils.ccompiler, with some
3011 parts of distutils calling one and others using the other.
3012 Complete the revert back to only having one in distutils.sysconfig as
3013 is the case in 3.x.
3014
Ned Deily0d0ea482012-02-10 12:59:06 +01003015- Issue #13590: On OS X 10.7 and 10.6 with Xcode 4.2, building
3016 Distutils-based packages with C extension modules may fail because
3017 Apple has removed gcc-4.2, the version used to build python.org
3018 64-bit/32-bit Pythons. If the user does not explicitly override
3019 the default C compiler by setting the CC environment variable,
3020 Distutils will now attempt to compile extension modules with clang
3021 if gcc-4.2 is required but not found. Also as a convenience, if
3022 the user does explicitly set CC, substitute its value as the default
3023 compiler in the Distutils LDSHARED configuration variable for OS X.
3024 (Note, the python.org 32-bit-only Pythons use gcc-4.0 and the 10.4u
3025 SDK, neither of which are available in Xcode 4. This change does not
3026 attempt to override settings to support their use with Xcode 4.)

Ned Deily87e82bb2011-06-28 19:52:59 -07003276- Issue #9516: On Mac OS X, change Distutils to no longer globally attempt to
3277 check or set the MACOSX_DEPLOYMENT_TARGET environment variable for the
3278 interpreter process. This could cause failures in non-Distutils subprocesses
3279 and was unreliable since tests or user programs could modify the interpreter
Ezio Melotti302ad8d2013-01-19 19:44:58 +02003280 environment after Distutils set it. Instead, have Distutils set the
Ned Deily87e82bb2011-06-28 19:52:59 -07003281 deployment target only in the environment of each build subprocess. It is
3282 still possible to globally override the default by setting
3283 MACOSX_DEPLOYMENT_TARGET before launching the interpreter; its value must be
3284 greater or equal to the default value, the value with which the interpreter
3285 was built.

3315 the ticker doesn't have to wind down to zero from the old starting point
3316 before the new interval takes effect. And if the user increases the
3317 interval, it makes sure the new limit takes effect right away rather have an
3318 early task switch before recognizing the new interval.

4316 This prevents user-created self-referencing ordered dictionaries from
4317 becoming permanently uncollectable GC garbage. The downside is that

4777
Ezio Melottiab2eb0e2010-06-05 19:21:32 +00004778- Issue #8271: during the decoding of an invalid UTF-8 byte sequence, only the
4779 start byte and the continuation byte(s) are now considered invalid, instead
4780 of the number of bytes specified by the start byte.
4781 E.g.: '\xf1\x80AB'.decode('utf-8', 'replace') now returns u'\ufffdAB' and
4782 replaces with U+FFFD only the start byte ('\xf1') and the continuation byte
4783 ('\x80') even if '\xf1' is the start byte of a 4-bytes sequence.
4784 Previous versions returned a single u'\ufffd'.

4788 arises from the "Overriding __eq__ blocks inheritance ..." warning
4789 when turned into an exception: in this case the exception simply
4790 gets ignored.

Mark Dickinson4ca7c3c2010-05-30 13:18:10 +00004792- Issue #8748: Fix two issues with comparisons between complex and integer
4793 objects. (1) The comparison could incorrectly return True in some cases
4794 (2**53+1 == complex(2**53) == 2**53), breaking transivity of equality.
4795 (2) The comparison raised an OverflowError for large integers, leading
4796 to unpredictable exceptions when combining integers and complex objects
4797 in sets or dicts.

Mark Dickinson81336372010-05-30 12:12:25 +00004799- Issue #5211: Implicit coercion for the complex type is now completely
4800 removed. (Coercion for arithmetic operations was already removed in 2.7
4801 alpha 4, but coercion for rich comparisons was accidentally left in.)
4802
Victor Stinnerc49dfcc2010-05-25 22:30:32 +00004803- Issue #3798: Write sys.exit() message to sys.stderr to use stderr encoding

Georg Brandlfee0f442010-05-22 21:26:21 +00004990- Issue #8567: Fix precedence of signals in Decimal module: when a Decimal
4991 operation raises multiple signals and more than one of those signals is
4992 trapped, the specification determines the order in which the signals should be
4993 handled. In many cases this order wasn't being followed, leading to the wrong
4994 Python exception being raised.

5180 with a non-empty format string. This is an effort to future-proof user
5181 code. If a derived class does not currently implement __format__ but later
5182 adds its own __format__, it would most likely break user code that had
Antoine Pitrou01a196a2011-01-02 20:05:11 +00005183 supplied a format string. This will be changed to a DeprecationWarning in
Georg Brandlfee0f442010-05-22 21:26:21 +00005184 Python 3.3 and it will be an error in Python 3.4.

Georg Brandlfee0f442010-05-22 21:26:21 +00005234- Issue #7279: Comparisons involving a Decimal signaling NaN now signal
5235 InvalidOperation instead of returning False. (Comparisons involving a quiet
5236 NaN are unchanged.) Also, Decimal quiet NaNs are now hashable; Decimal
5237 signaling NaNs remain unhashable.

Georg Brandlfee0f442010-05-22 21:26:21 +00005239- Issue #2531: Comparison operations between floats and Decimal instances now
5240 return a result based on the numeric values of the operands; previously they
5241 returned an arbitrary result based on the relative ordering of id(float) and
5242 id(Decimal).

Barry Warsawf7f2d6f2010-03-31 21:07:16 +00005244- Issue #8233: When run as a script, py_compile.py optionally takes a single
Georg Brandlfee0f442010-05-22 21:26:21 +00005245 argument `-` which tells it to read files to compile from stdin. Each line is
5246 read on demand and the named file is compiled immediately. (Original patch by
5247 Piotr Ożarowski).

Georg Brandlfee0f442010-05-22 21:26:21 +00005256- Comparisons using one of <, <=, >, >= between a complex instance and a
5257 Fractions instance now raise TypeError instead of returning True/False. This
5258 makes Fraction <=> complex comparisons consistent with int <=> complex, float
5259 <=> complex, and complex <=> complex comparisons.

5359 integer format code, struct.pack first attempts to convert the non-integer

5362
Georg Brandlba83f822010-03-14 09:50:54 +00005363- Issue #1530559: When passing a non-integer argument to struct.pack with *any*
5364 integer format code (one of 'bBhHiIlLqQ'), struct.pack attempts to use the
5365 argument's __int__ method to convert to an integer before packing. It also
Georg Brandlfee0f442010-05-22 21:26:21 +00005366 produces a DeprecationWarning in this case. (In Python 2.6, the behaviour was
5367 inconsistent: __int__ was used for some integer codes but not for others, and
5368 the set of integer codes for which it was used differed between native packing
5369 and standard packing.)

Georg Brandlba83f822010-03-14 09:50:54 +00005677 file position when calling `truncate()`. It would previously change the file
5678 position to the given argument, which goes against the tradition of

5682 class used to represent files stored inside an archive. The new
5683 implementation is significantly faster and can be wrapped in a

Georg Brandlba83f822010-03-14 09:50:54 +00005776- The ``__complex__()`` method is now looked up on the class of instances to
5777 make it consistent with other special methods.

5781
Mark Dickinson1b34d252010-01-01 17:27:30 +00005782- Issue #5080: A number of functions and methods previously produced a
Georg Brandlba83f822010-03-14 09:50:54 +00005783 DeprecationWarning when passed a float argument where an integer was expected.
5784 These functions and methods now raise TypeError instead. The majority of the
5785 effects of this change are in the extension modules, but some core functions
5786 and methods are affected: notably the 'chr', 'range' and 'xrange' builtins,
5787 and many unicode/str methods.

Georg Brandlba83f822010-03-14 09:50:54 +00005948- Issue #7419: ``locale.setlocale()`` could crash the interpreter on Windows
5949 when called with invalid values.

Georg Brandlba83f822010-03-14 09:50:54 +00005951- Issue #3382: 'F' formatting for float and complex now convert the result to
5952 upper case. This only affects 'inf' and 'nan', since 'f' no longer converts
5953 to 'g' for large values.
Amaury Forgeot d'Arcd7288712009-12-01 21:51:04 +00005954
Georg Brandlba83f822010-03-14 09:50:54 +00005955- Remove switch from "%f" formatting to "%g" formatting for floats larger than
5956 1e50 in absolute value.
Mark Dickinson9dd5e162009-11-23 20:54:09 +00005957
Georg Brandlba83f822010-03-14 09:50:54 +00005958- Remove restrictions on precision when formatting floats. E.g., "%.120g" %
5959 1e-100 used to raise OverflowError, but now gives the requested 120
5960 significant digits instead.
Mark Dickinson18cfada2009-11-23 18:46:41 +00005961
Georg Brandlba83f822010-03-14 09:50:54 +00005962- Add Py3k warnings for parameter names in parentheses.

5967 10.6.
Ronald Oussoren315cd0c2009-11-19 16:25:21 +00005968
Georg Brandlba83f822010-03-14 09:50:54 +00005969- Issue #7117: ``repr(x)`` for a float x returns a result based on the shortest
5970 decimal string that's guaranteed to round back to x under correct rounding
5971 (with round-half-to-even rounding mode). Previously it gave a string based on
5972 rounding x to 17 decimal digits. repr(x) for a complex number behaves
5973 similarly. On platforms where the correctly-rounded strtod and dtoa code is
5974 not supported (see below), repr is unchanged.
Mark Dickinsonb678de82009-11-19 18:41:49 +00005975
Georg Brandlba83f822010-03-14 09:50:54 +00005976- Issue #7117: On almost all platforms: float-to-string and string-to-float
5977 conversions within Python are now correctly rounded. Places these conversions
5978 occur include: str for floats and complex numbers; the float and complex
5979 constructors; old-style and new-style numeric formatting; serialization and
5980 deserialization of floats and complex numbers using marshal, pickle and json;
5981 parsing of float and imaginary literals in Python code; Decimal-to-float
5982 conversion.
Mark Dickinsonb678de82009-11-19 18:41:49 +00005983
Georg Brandlba83f822010-03-14 09:50:54 +00005984 The conversions use a Python-adapted version of David Gay's well-known dtoa.c,
5985 providing correctly-rounded strtod and dtoa C functions. This code is
5986 supported on Windows, and on Unix-like platforms using gcc, icc or suncc as
5987 the C compiler. There may be a small number of platforms on which correct
5988 operation of this code cannot be guaranteed, so the code is not used: notably,
5989 this applies to platforms where the C double format is not IEEE 754 binary64,
5990 and to platforms on x86 hardware where the x87 FPU is set to 64-bit precision
5991 and Python's configure script is unable to determine how to change the FPU
5992 precision. On these platforms conversions use the platform strtod and dtoa,
5993 as before.
Mark Dickinsonb678de82009-11-19 18:41:49 +00005994
Georg Brandlba83f822010-03-14 09:50:54 +00005995- Issue #7117: Backport round implementation from Python 3.x. ``round()`` now
5996 uses the correctly-rounded string <-> float conversions described above (when
5997 available), and so produces correctly rounded results that will display nicely
5998 under the float repr. There are two related small changes: (1) round now
5999 accepts any class with an ``__index__()`` method for its second argument (but
6000 no longer accepts floats for the second argument), and (2) an excessively
6001 large second integer argument (e.g., ``round(1.234, 10**100)``) no longer
6002 raises an exception.

6005
Georg Brandlba83f822010-03-14 09:50:54 +00006006- Fix several issues with ``compile()``. The input can now contain Windows and

6038 The tables for code points representing numeric values, white spaces or line
6039 breaks are now generated from the official Unicode Character Database files,
6040 and include information from the Unihan.txt file.

Georg Brandlba83f822010-03-14 09:50:54 +00006149- Issue #5920: For ``float.__format__()``, change the behavior with the empty
6150 presentation type (that is, not one of 'e', 'f', 'g', or 'n') to be like 'g'
6151 but with at least one decimal point and with a default precision
6152 of 12. Previously, the behavior the same but with a default precision of 6.
6153 This more closely matches ``str()``, and reduces surprises when adding

Georg Brandlba83f822010-03-14 09:50:54 +00007665 leak-chasing test runs give sensible results. The previous method of reaping
7666 threads could return successfully while some Thread objects were still
7667 referenced. This also introduces a new private function: ``thread._count()``.

7789 exactly the recursion limit is exceeded. Consequently, both exception types
7790 are caught and silenced.

7806
Martin v. Löwis9fa5a282008-09-11 06:53:30 +00007807- Issue #3642: Suppress warning in obmalloc when size_t is larger than uint.
7808
Amaury Forgeot d'Arc05e34492008-09-10 22:04:45 +00007809- Issue #3743: In a few places, PY_FORMAT_SIZE_T was incorrectly used with
7810 PyString_FromFormat or PyErr_Format to display size_t values. The macro
7811 PY_FORMAT_SIZE_T is designed to select the correct format for the OS
7812 ``printf`` function, whereas PyString_FromFormat has an independent
7813 implementation and uses "%zd" on all platforms for size_t values.
7814 This makes a difference on win64, where ``printf`` needs "%Id" to display
7815 64bit values.
7816
Benjamin Peterson97179b02008-09-09 20:55:01 +00007817- Issue #3634: _weakref.ref(Exception).__init__() gave invalid return value on
7818 error.
7819
Amaury Forgeot d'Arcd3ffb892008-09-09 07:24:30 +00007820- Issue #3777: long() applied to a float object now always return a long
7821 object; previously an int would be returned for small values. the __long__
7822 method is allowed to return either an int or a long, but the behaviour of
7823 float objects should not change to respect backward compatibility.
7824
Amaury Forgeot d'Arc3571fbf2008-09-01 19:52:00 +00007825- Issue #3751: str.rpartition would perform a left-partition when called with
7826 a unicode argument.
7827
Benjamin Peterson17f03ca2008-09-01 14:18:30 +00007828- Issue #3683: Fix compilation when --without-threads is given.
7829
Antoine Pitroud4ae97b2008-08-29 18:39:48 +00007830- Issue #3668: Fix a memory leak with the "s*" argument parser in
Vinay Sajip35e3b032008-09-01 14:33:59 +00007831 PyArg_ParseTuple and friends, which occurred when the argument for "s*"
Antoine Pitroud4ae97b2008-08-29 18:39:48 +00007832 was correctly parsed but parsing of subsequent arguments failed.
7833
Vinay Sajip35e3b032008-09-01 14:33:59 +00007834- Issue #2534: speed up isinstance() and issubclass() by 50-70%, so as to
Antoine Pitrou0668c622008-08-26 22:42:08 +00007835 match Python 2.5 speed despite the __instancecheck__ / __subclasscheck__
7836 mechanism. In the process, fix a bug where isinstance() and issubclass(),
7837 when given a tuple of classes as second argument, were looking up
7838 __instancecheck__ / __subclasscheck__ on the tuple rather than on each
7839 type object.
7840
Neal Norwitz18aa3882008-08-24 05:04:52 +00007841- Fix crashes on memory allocation failure found with failmalloc.
7842
7843- Fix memory leaks found with valgrind and update suppressions file.
7844
7845- Fix compiler warnings in opt mode which would lead to invalid memory reads.
7846
7847- Fix problem using wrong name in decimal module reported by pychecker.
7848
Christian Heimes7d4c3172008-08-22 19:47:25 +00007849- Silenced another compiler warning about a used but not defined
7850 function 'stringlib_contains_obj'.

7853 ``__delslice__``.
7854
Gregory P. Smith2bb25cc2008-09-02 05:29:51 +00007855- Issue #3678: Correctly pass LDFLAGS and LDLAST to the linker on shared
7856 library targets in the Makefile.
7857
Gregory P. Smith980b99b2008-09-07 05:15:18 +00007858- Issue #1204: The configure script now tests for additional libraries
7859 that may be required when linking against readline. This fixes issues
7860 with x86_64 builds on some platforms (a few Linux flavors and OpenBSD).

Brett Cannon1eaf0742008-09-02 01:25:16 +00007910 warnings.catch_warnings() along with some API cleanup. Expanding the tests
7911 for catch_warnings() also led to an improvement in the raising of a
7912 DeprecationWarning related to warnings.warn_explicit().
7913
Benjamin Peterson973e6c22008-09-01 23:12:58 +00007914- The deprecation warnings for the old camelCase threading API were removed.

Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00007978What's New in Python 2.6 beta 3?
7979================================
7980
Barry Warsaw07a4a382008-08-21 01:15:08 +00007981*Release date: 20-Aug-2008*
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00007982
7983Core and Builtins
7984-----------------
7985
Guido van Rossumf8402962008-08-20 15:01:50 +00007986- Issue #1878: Remove Py_TPFLAGS_HAVE_VERSION_TAG from
7987 Py_TPFLAGS_DEFAULT when not building the core. This means 3rd party
7988 extensions do not automatically benefit from the class attribute
7989 cache; they will have to explicitly add Py_TPFLAGS_HAVE_VERSION_TAG
7990 to their tp_flags field if they care. This is a backwards
7991 compatibility feature; in 3.0, all types will use the cache by
7992 default.
7993
Benjamin Petersonf647dc12008-08-20 01:27:30 +00007994- Keyword arguments can now follow starred arguments. (``f(a, *args,
7995 keyword=23)`` is now valid syntax.)
7996
Thomas Heller0ad5ae02008-08-19 19:25:04 +00007997- ctypes function pointers that are COM methods have a boolean True
7998 value again.
7999
Martin v. Löwisf91d46a2008-08-12 14:49:50 +00008000- Issue #3139: Make buffer-interface thread-safe wrt. PyArg_ParseTuple,
8001 by denying s# to parse objects that have a releasebuffer procedure,
8002 and introducing s*.
8003
Georg Brandl1e13ea92008-08-11 09:07:59 +00008004- Issue #3537: Fix an assertion failure when an empty but presized dict
8005 object was stored in the freelist.
8006
Mark Dickinsonb6467572008-08-04 21:30:09 +00008007- Issue #1481296: Make long(float('nan')) and int(float('nan')) raise
8008 ValueError consistently across platforms.
8009
Amaury Forgeot d'Arc39fd6722008-07-31 21:28:03 +00008010- Issue #3479: On platforms where sizeof(int) is smaller than sizeof(long)
8011 (64bit Unix, for example), unichr() would truncate its argument and return
8012 u'\x00' for unichr(2**32). Now it properly raises an OverflowError.
8013
Neal Norwitze7d8be82008-07-31 17:17:14 +00008014- Apply security patches from Apple.
8015
Amaury Forgeot d'Arc246daed2008-07-31 00:42:16 +00008016- Issue #2542: Now that issubclass() may call arbitrary code, ensure that
8017 PyErr_ExceptionMatches returns 0 when an exception occurs there.
8018
Antoine Pitrou92f82162008-07-25 22:22:08 +00008019- Issue #1819: function calls with several named parameters are now on
8020 average 35% faster (as measured by pybench).
8021
Amaury Forgeot d'Arce4921fe2008-07-21 22:00:38 +00008022- Issue #2378: An unexpected UnboundLocalError or NameError could appear when
8023 the python debugger steps into a class statement: the free variables (local
8024 variables defined in an outer scope) would be deleted from the outer scope.
8025
Gregory P. Smith0470bab2008-07-22 04:46:32 +00008026- Issue #2620: Overflow checking when allocating or reallocating memory
8027 was not always being done properly in some python types and extension
8028 modules. PyMem_MALLOC, PyMem_REALLOC, PyMem_NEW and PyMem_RESIZE have
8029 all been updated to perform better checks and places in the code that
8030 would previously leak memory on the error path when such an allocation
8031 failed have been fixed.

8037
Benjamin Petersone977ad42008-08-20 01:42:01 +00008038- The methods ``is_in_tuple()``, ``is_vararg()``, and ``is_keywordarg()`` of
8039 symtable.Symbol have been deprecated for removal in 3.0 and the next release.
8040
Amaury Forgeot d'Arc351ffb82008-08-18 19:23:47 +00008041- Issue #2234: distutils failed for some versions of the cygwin compiler. The
8042 version reported by these tools does not necessarily follow the python
8043 version numbering scheme, so the module is less strict when parsing it.
8044
Nick Coghlanf70385a2008-08-18 12:42:46 +00008045- Issue #2235: Added Py3k warnings for types which will become unhashable
8046 under the stricter __hash__ inheritance rules in 3.0. Several types
8047 which did not meet the rules for hash invariants and were already
8048 unhashable in 3.0 have now been explicitly flagged as unhashable in
8049 2.6 as well (collections.Mapping, collections.Set, unittest.TestSuite,
8050 xml.dom.minidom.NamedNodeMap, numbers.Number, UserList.UserList)
8051
Brett Cannon88f801d2008-08-18 00:46:22 +00008052- Update __all__ for cookielib, csv, os, urllib2, and weakref to include things
8053 imported into the module but exposed as part of the module's API.
8054
Brett Cannon7b96f072008-08-18 00:41:11 +00008055- Remove an unneeded import of abc.ABCMeta from 'inspect'.

8060
Hirokazu Yamamoto41a81eb2008-08-17 13:10:46 +00008061- Issue #3575: Incremental decoder's decode function now takes bytearray
8062 by using 's*' instead of 't#'.
8063
Mark Dickinson3e4caeb2009-02-21 20:27:01 +00008064- Issue #2222: Fixed reference leak when occurred os.rename()
Hirokazu Yamamoto7f30a682008-08-17 09:46:56 +00008065 fails unicode conversion on 2nd parameter. (windows only)
8066
Georg Brandl222e2082010-08-01 22:27:39 +00008067- Issue #2464: urllib2 now supports a malformation in the URL received

Antoine Pitroude781a42008-08-09 12:43:23 +00008121 asking for a specific length. This problem only affected files opened

8165
Nick Coghlan2a0c2b12008-08-04 12:47:17 +00008166- Issue #643841: The language reference now provides more detailed

8179
Georg Brandl3e483f62008-07-16 22:57:41 +00008180- Issue #3156: Fix inconsistent behavior of the bytearray type: all
8181 its methods now allow for items objects that can be converted to
8182 an integer using operator.index().
8183
Mark Dickinson64b7e502008-07-16 09:40:03 +00008184- Issue #3360: Fix incorrect parsing of '020000000000.0', which
8185 produced a ValueError instead of giving the correct float.
8186
Eric Smitha5fa5a22008-07-16 00:11:49 +00008187- Issue #3083: Add alternate (#) formatting for bin, oct, hex output
8188 for str.format(). This adds the prefix 0b, 0o, or 0x, respectively.
8189
Mark Dickinson7103aa42008-07-15 19:08:33 +00008190- Issue #3008: the float type has a new instance method 'float.hex'
8191 and a new class method 'float.fromhex' to convert floating-point
8192 numbers to and from hexadecimal strings, respectively.
8193
Nick Coghlan6d6bd442008-07-15 15:40:22 +00008194- Issue #2235: __hash__ is once again inherited by default. To allow
8195 collections.Hashable to remain meaningful in the presence of the
8196 default hash implementation (object.__hash__), it is now possible
8197 to explicit block inheritance of hash by setting __hash__=None at
8198 the Python level, or tp_hash=PyObject_HashNotImplemented at the C
8199 level.
8200
Nick Coghlanb028f502008-07-13 14:52:36 +00008201- Issue #3221: Issue a RuntimeWarning instead of raising SystemError if
8202 the parent module cannot be found while performing an absolute import.
8203 This means that an incorrectly defined __package__ attribute will
8204 now only prevent relative imports in that module rather than causing
8205 all imports from that module to fail.
8206
Nick Coghlan14ff9942008-07-08 14:21:42 +00008207- Issue #2517: Allow unicode messages in Exceptions again by correctly

8217 another thread's dictionary.
8218
Mark Dickinson1ec2fcd2008-06-20 14:53:43 +00008219- Issue #3004: Minor change to slice.indices(): the start and stop
8220 arguments are now treated identically, making the behaviour easier
8221 to describe and understand. For example, slice(None, -10,
8222 1).indices(9) now returns (0, 0, 1) instead of (0, -1, 1), and
8223 slice(None, 10, -1).indices(10) returns (9, 9, -1) instead of (9,
8224 10, -1).

Georg Brandl278fc502008-07-19 12:46:12 +00008226- Issue #3219: Calling a function with repeated keyword arguments,

8267 both unnecessary (HTTP allows text content to be sent in several forms) and
Andrew M. Kuchlingcc3f2b12008-07-10 14:43:31 +00008268 wrong because the actual transmitted size could differ from the
Amaury Forgeot d'Arc0f7cddc2008-07-06 21:34:39 +00008269 content-length. The problem had been corrected in the 2.4 branch, but never

8673
Ronald Oussoren5640ce22008-06-05 12:58:24 +00008674- On MacOS X it is now possible to install the framework in 64-bit
8675 mode or even as a 4-way universal binary (that is, PPC, i386,
Georg Brandl5cc774e2008-06-11 20:28:06 +00008676 PPC64 and x86_64 support in one binary).
Ronald Oussoren5640ce22008-06-05 12:58:24 +00008677
8678 This is controlled by the configure argument ``--with-universal-archs``:
8679
8680 - ``--with-universal-archs=all``: install 4-way universal
8681
8682 - ``--with-universal-archs=32-bit``: install 2-way universal, 32-bit (the default)
8683
8684 - ``--with-universal-archs=64-bit``: install 2-way universal, 64-bit
8685
8686 This option should be used in combination with ``--enable-universalsdk=``.
8687
8688 NOTE: 64-bit and 4-way builds are only suppported on Mac OS X 10.5 (or later).

8697- The PyString functions have been renamed to PyBytes. A batch of
8698 defines were added so that the linker still sees the original
8699 PyString names.

Georg Brandl3ee81df2008-05-17 18:14:43 +00008737- Issue #1631171: Re-implement the 'warnings' module in C (the
8738 original Python code has been kept as backup). This will allow for
8739 using the 'warning's machinery in such places as the parser where
8740 use of pure Python code is not possible. Both the ``showarning()``
8741 and ``formatwarning()`` gain an optional 'line' argument which is
8742 not called by default for backwards-compatibility reasons. Setting
8743 ``warnings.showwarning()`` to an implementation that lacks support
8744 for the ``line`` argument will raise a DeprecationWarning.

Georg Brandl3ee81df2008-05-17 18:14:43 +00008786- Issue #2513: distutils on Windows is now capable of cross-compiling
Mark Hammond495cf992008-04-07 01:53:39 +00008787 extension modules between 32 and 64 bit platforms. See the distutls

Georg Brandl3ee81df2008-05-17 18:14:43 +00008807- Issue #2550: The approach used by client/server code for obtaining
8808 ports to listen on in network-oriented tests has been refined in an
8809 effort to facilitate running multiple instances of the entire
8810 regression test suite in parallel without issue.
8811 test_support.bind_port() has been fixed such that it will always
8812 return a unique port -- which wasn't always the case with the
8813 previous implementation, especially if socket options had been set
8814 that affected address reuse (i.e. SO_REUSEADDR, SO_REUSEPORT). The
8815 new implementation of bind_port() will actually raise an exception
8816 if it is passed an AF_INET/SOCK_STREAM socket with either the
8817 SO_REUSEADDR or SO_REUSEPORT socket option set. Furthermore, if
8818 available, bind_port() will set the SO_EXCLUSIVEADDRUSE option on
8819 the socket it's been passed. This currently only applies to
8820 Windows. This option prevents any other sockets from binding to the
8821 host/port we've bound to, thus removing the possibility of the
8822 'non-deterministic' behaviour, as Microsoft puts it, that occurs
8823 when a second SOCK_STREAM socket binds and accepts to a host/port
8824 that's already been bound by another socket. The optional preferred
8825 port parameter to bind_port() has been removed. Under no
8826 circumstances should tests be hard coding ports!
8827
8828 test_support.find_unused_port() has also been introduced, which will
8829 pass a temporary socket object to bind_port() in order to obtain an
8830 unused port. The temporary socket object is then closed and
8831 deleted, and the port is returned. This method should only be used
8832 for obtaining an unused port in order to pass to an external program
8833 (i.e. the -accept [port] argument to openssl's s_server mode) or as
8834 a parameter to a server-oriented class that doesn't give you direct
8835 access to the underlying socket used.
8836
8837 Finally, test_support.HOST has been introduced, which should be used
8838 for the host argument of any relevant socket calls (i.e. bind and
8839 connect).
Trent Nelsone41b0062008-04-08 23:47:30 +00008840
8841 The following tests were updated to following the new conventions:
Georg Brandl3ee81df2008-05-17 18:14:43 +00008842 test_socket, test_smtplib, test_asyncore, test_ssl, test_httplib,
Trent Nelsone41b0062008-04-08 23:47:30 +00008843 test_poplib, test_ftplib, test_telnetlib, test_socketserver,
8844 test_asynchat and test_socket_ssl.
8845
Georg Brandl3ee81df2008-05-17 18:14:43 +00008846 It is now possible for multiple instances of the regression test
8847 suite to run in parallel without issue.

Eric Smitha73fbe72008-02-23 03:09:44 +00009126- Added the future_builtins module, which contains hex() and oct().
9127 These are the PEP 3127 version of these functions, designed to be
9128 compatible with the hex() and oct() builtins from Python 3.0. They
9129 differ slightly in their output formats from the existing, unchanged
9130 Python 2.6 builtins. The expected usage of the future_builtins
9131 module is:
9132 from future_builtins import hex, oct
9133
Eric Smith7ef40bf2008-02-20 23:34:22 +00009134- Issue #1600: Modifed PyOS_ascii_formatd to use at most 2 digit
9135 exponents for exponents with absolute value < 100. Follows C99
9136 standard. This is a change on Windows, which would use 3 digits.
9137 Also, added 'n' to the formats that PyOS_ascii_formatd understands,
9138 so that any alterations it does to the resulting string will be
9139 available in stringlib/formatter.h (for float.__format__).
9140
Eric Smith5a3c1352008-02-19 13:21:56 +00009141- Implemented PEP 3101, Advanced String Formatting. This adds a new
9142 builtin format(); a format() method for str and unicode; a
9143 __format__() method to object, str, unicode, int, long, float, and
9144 datetime; the class string.Formatter; and the C API
9145 PyObject_Format().
9146
Georg Brandl3ee81df2008-05-17 18:14:43 +00009147- Fixed several potential crashes, all caused by specially crafted
9148 __del__ methods exploiting objects in temporarily inconsistent
9149 state.

Georg Brandl3ee81df2008-05-17 18:14:43 +00009155- Fixed repr() and str() of complex numbers with infinity or nan as
9156 real or imaginary part.
Christian Heimes2f0da532008-02-15 06:57:08 +00009157
Georg Brandl3ee81df2008-05-17 18:14:43 +00009158- Clear all free lists during a gc.collect() of the highest generation
9159 in order to allow pymalloc to free more arenas. Python may give back
9160 memory to the OS earlier.
Christian Heimes3b718a72008-02-14 12:47:33 +00009161
Georg Brandl3ee81df2008-05-17 18:14:43 +00009162- Issue #2045: Fix an infinite recursion triggered when printing a
9163 subclass of collections.defaultdict, if its default_factory is set
9164 to a bound method.
Amaury Forgeot d'Arcb01aa432008-02-08 00:56:02 +00009165
Christian Heimesf75dbef2008-02-08 00:11:31 +00009166- Fixed a minor memory leak in dictobject.c. The content of the free
9167 list was not freed on interpreter shutdown.
9168
Georg Brandl21e99f42010-03-07 15:23:59 +00009169- Limit free list of method and built-in function objects to 256
Georg Brandl3ee81df2008-05-17 18:14:43 +00009170 entries each.
Christian Heimes6075a822008-02-06 12:44:34 +00009171
Georg Brandl3ee81df2008-05-17 18:14:43 +00009172- Patch #1953: Added ``sys._compact_freelists()`` and the C API
9173 functions ``PyInt_CompactFreeList`` and ``PyFloat_CompactFreeList``
Christian Heimes422051a2008-02-04 18:00:12 +00009174 to compact the internal free lists of pre-allocted ints and floats.
9175
Georg Brandl3ee81df2008-05-17 18:14:43 +00009176- Issue #1983: Fixed return type of fork(), fork1() and forkpty()
9177 calls. Python expected the return type int but the fork familie
9178 returns pi_t.
Christian Heimes951cc0f2008-01-31 23:08:23 +00009179
Georg Brandl3ee81df2008-05-17 18:14:43 +00009180- Issue #1678380: Fix a bug that identifies 0j and -0j when they
9181 appear in the same code unit.
Mark Dickinson105be772008-01-31 22:17:37 +00009182
Georg Brandl3ee81df2008-05-17 18:14:43 +00009183- Issue #2025: Add tuple.count() and tuple.index() methods to comply
9184 with the collections.Sequence API.
Raymond Hettinger5b07ebc2008-02-07 00:54:20 +00009185
Georg Brandl3ee81df2008-05-17 18:14:43 +00009186- Patch #1970 by Antoine Pitrou: Speedup unicode whitespace and
9187 linebreak detection

Georg Brandl3ee81df2008-05-17 18:14:43 +00009189- Added ``PyType_ClearCache()`` and ``sys._clear_type_cache`` to clear
9190 the internal lookup cache for ref leak tests.
Christian Heimes908caac2008-01-27 23:34:59 +00009191
Georg Brandl3ee81df2008-05-17 18:14:43 +00009192- Patch #1473257: generator objects gain a gi_code attribute. This is
9193 the same object as the func_code attribute of the function that
9194 produced the generator.
Georg Brandl0cdf9a32008-01-26 14:14:20 +00009195
Georg Brandl3ee81df2008-05-17 18:14:43 +00009196- Issue #1920: "while 0" statements were completely removed by the
9197 compiler, even in the presence of an "else" clause, which is
9198 supposed to be run when the condition is false. Now the compiler
9199 correctly emits bytecode for the "else" suite.
Amaury Forgeot d'Arc31eaafe2008-01-24 22:59:25 +00009200
Guido van Rossumeead05f2008-01-24 18:21:02 +00009201- A few crashers fixed: weakref_in_del.py (issue #1377858);
9202 loosing_dict_ref.py (issue #1303614, test67.py);
9203 borrowed_ref_[34].py (not in tracker).
9204
Vinay Sajipd7cf32e2008-01-24 12:43:33 +00009205- Issue #1069410: The "can't load dll" message box on Windows is
Christian Heimesb2302ba2008-01-23 17:15:06 +00009206 suppressed while an extension is loaded by calling SetErrorMode in
9207 dynload_win.c. The error is still reported properly.
9208
Georg Brandl3ee81df2008-05-17 18:14:43 +00009209- Issue #1915: Python compiles with --enable-unicode=no again. However
Christian Heimes082c9b02008-01-23 14:20:50 +00009210 several extension methods and modules do not work without unicode
9211 support.
9212
Georg Brandl26543b12008-01-21 18:36:51 +00009213- Issue #1882: when compiling code from a string, encoding cookies in the
9214 second line of code were not always recognized correctly.
9215
Georg Brandl14404b62008-01-19 19:27:05 +00009216- Issue #1679: "0x" was taken as a valid integer literal.
9217
Georg Brandl6caad7d2008-01-26 14:19:22 +00009218- Issue #1865: ``bytes`` as an alias for ``str`` and b"" as an alias "" were
Christian Heimes288e89a2008-01-18 18:24:07 +00009219 added.
9220
Christian Heimesc94e2b52008-01-14 04:13:37 +00009221- sys.float_info / PyFloat_GetInfo: The floating point information
9222 object was converted from a dict to a specialized structseq object.
9223
Georg Brandl3ee81df2008-05-17 18:14:43 +00009224- Patch #1816: Added sys.flags structseq. It exposes the status of
9225 most command line arguments and PYTHON* environment variables.
Christian Heimesf31b69f2008-01-14 03:42:48 +00009226
Georg Brandl3ee81df2008-05-17 18:14:43 +00009227- Objects/structseq.c: Implemented new structseq representation. The
9228 patch makes structseqs (e.g. the return value of os.stat) more
9229 readable.
Christian Heimes9c201962008-01-14 03:33:52 +00009230
Georg Brandl3ee81df2008-05-17 18:14:43 +00009231- Patch #1700288: added a type attribute cache that caches method
9232 accesses, resulting in speedups in heavily object-oriented code.
Amaury Forgeot d'Arce4c270c2008-01-14 00:29:41 +00009233
Neal Norwitz3fc15b82008-01-10 05:42:58 +00009234- Bug #1776: __import__() no longer accepts filenames on any platform.
9235 The first parameter to __import__() must be a valid module name.
Christian Heimes3403f152008-01-09 19:56:33 +00009236
Georg Brandlaed6c662008-01-07 17:25:53 +00009237- Patch #1668: renamed THREADDEBUG envvar to PYTHONTHREADDEBUG.
9238
Georg Brandl3ee81df2008-05-17 18:14:43 +00009239- Patch #602345: Add -B command line option, PYTHONDONTWRITEBYTECODE
9240 envvar and sys.dont_write_bytecode attribute. All these can be set
9241 to forbid Python to attempt to write compiled bytecode files.
Georg Brandl2da0fce2008-01-07 17:09:35 +00009242
Georg Brandl3ee81df2008-05-17 18:14:43 +00009243- Improve some exception messages when Windows fails to load an
9244 extension module. Now we get for example '%1 is not a valid Win32
9245 application' instead of 'error code 193'.
Amaury Forgeot d'Arce0b76952008-01-04 02:04:15 +00009246
Georg Brandl3ee81df2008-05-17 18:14:43 +00009247- Bug #1481296: Fixed long(float('nan')) != 0L.

9250 y) functions.
Christian Heimese2ca4242008-01-03 20:23:15 +00009251
Christian Heimes0a8143f2007-12-18 23:22:54 +00009252- Issue #1635: Platform independent creation and representation of NaN
Georg Brandl3ee81df2008-05-17 18:14:43 +00009253 and INF. float("nan"), float("inf") and float("-inf") now work on
9254 every platform with IEEE 754 semantics.
Christian Heimes0a8143f2007-12-18 23:22:54 +00009255
Georg Brandl3ee81df2008-05-17 18:14:43 +00009256- Compiler now generates simpler and faster code for dictionary
9257 literals. The oparg for BUILD_MAP now indicates an estimated
9258 dictionary size. There is a new opcode, STORE_MAP, for adding
9259 entries to the dictionary.
Raymond Hettingerfd7ed402007-12-18 21:24:09 +00009260
Georg Brandl3ee81df2008-05-17 18:14:43 +00009261- Issue #1638: %zd configure test fails on Linux.

Georg Brandl3ee81df2008-05-17 18:14:43 +00009288- Patch #1739468: Directories and zipfiles containing a __main__.py
9289 file can now be directly executed by passing their name to the
9290 interpreter. The directory/zipfile is automatically inserted as the
9291 first entry in sys.path.
Nick Coghlan327a39b2007-11-18 11:56:28 +00009292
Georg Brandl3ee81df2008-05-17 18:14:43 +00009293- Issue #1265: Fix a problem with sys.settrace, if the tracing
9294 function uses a generator expression when at the same time the
9295 executed code is closing a paused generator.
Amaury Forgeot d'Arc0d75f092007-11-13 21:54:28 +00009296
Raymond Hettinger1760c8a2007-11-08 02:52:43 +00009297- sets and frozensets now have an isdisjoint() method.
9298
Raymond Hettinger3f8caa32007-10-24 01:28:33 +00009299- optimize the performance of builtin.sum().
9300
Neal Norwitz44f326e2007-10-05 05:29:17 +00009301- Fix warnings found by the new version of the Coverity checker.
9302
Georg Brandl21e99f42010-03-07 15:23:59 +00009303- The enumerate() built-in function is no longer bounded to sequences
Georg Brandl3ee81df2008-05-17 18:14:43 +00009304 smaller than LONG_MAX. Formerly, it raised an OverflowError. Now,
9305 automatically shifts from ints to longs.
Raymond Hettinger8f669372007-10-03 21:18:11 +00009306
Georg Brandl3ee81df2008-05-17 18:14:43 +00009307- Issue #1686386: Tuple's tp_repr did not take into account the
9308 possibility of having a self-referential tuple, which is possible
9309 from C code. Nor did object's tp_str consider that a type's tp_str
9310 could do something that could lead to an inifinite recursion.
9311 Py_ReprEnter() and Py_EnterRecursiveCall(), respectively, fixed the
9312 issues.
Brett Cannon0b14f242007-09-30 19:45:10 +00009313
Georg Brandl3ee81df2008-05-17 18:14:43 +00009314- Issue #1164: It was possible to trigger deadlock when using the
9315 'print' statement to write to a file since the GIL was not released
9316 as needed. Now PyObject_Print() does the right thing along with
9317 various tp_print implementations of the built-in types and those in
9318 the collections module.
Brett Cannon01531592007-09-17 03:28:34 +00009319
Georg Brandl3ee81df2008-05-17 18:14:43 +00009320- Issue #1147: Exceptions were directly allowing string exceptions in
9321 their throw() method even though string exceptions no longer
9322 allowed.
Brett Cannon4c20bc42007-09-11 21:02:28 +00009323
Georg Brandl3ee81df2008-05-17 18:14:43 +00009324- Issue #1096: Prevent a segfault from getting the repr of a very
9325 deeply nested list by using the recursion counter.
Brett Cannona0c05512007-09-10 21:38:27 +00009326
Brett Cannon1e534b52007-09-07 04:18:30 +00009327- Issue #1202533: Fix infinite recursion calls triggered by calls to
Georg Brandl3ee81df2008-05-17 18:14:43 +00009328 PyObject_Call() never calling back out to Python code to trigger
9329 recursion depth updates/checks. Required the creation of a static
9330 RuntimeError instance in case normalizing an exception put the
9331 recursion check value past its limit. Fixes crashers
9332 infinite_rec_(1|2|4|5).py.
Brett Cannon1e534b52007-09-07 04:18:30 +00009333
Georg Brandl3ee81df2008-05-17 18:14:43 +00009334- Patch #1031213: Decode source line in SyntaxErrors back to its

Neal Norwitz0ac60192007-05-27 04:08:54 +00009347- Add new attribute names for function objects. All the func_* become
Georg Brandl3ee81df2008-05-17 18:14:43 +00009348 __*__ attributes. (Some already existed, e.g., __doc__ and
9349 __name__.)
Neal Norwitz0ac60192007-05-27 04:08:54 +00009350
Neal Norwitz8b2bfbc2007-05-23 06:35:32 +00009351- Add -3 option to the interpreter to warn about features that are
9352 deprecated and will be changed/removed in Python 3.0.
9353
Georg Brandl2134e752007-05-21 20:34:16 +00009354- Patch #1686487: you can now pass any mapping after '**' in function
9355 calls.
9356
Collin Winter62903052007-05-18 23:11:24 +00009357- except clauses may now be spelled either "except E, target:" or
Georg Brandl3ee81df2008-05-17 18:14:43 +00009358 "except E as target:". This is to provide forwards compatibility
9359 with Python 3.0.
Collin Winter62903052007-05-18 23:11:24 +00009360
Brett Cannon229cee22007-05-05 01:34:02 +00009361- Deprecate BaseException.message as per PEP 352.
9362
Georg Brandl3ee81df2008-05-17 18:14:43 +00009363- Issue #1303614: don't expose object's __dict__ when the dict is
Georg Brandl21e99f42010-03-07 15:23:59 +00009364 inherited from a built-in base.
Armin Rigo9790a272007-05-02 19:23:31 +00009365
Vinay Sajip8549ce32007-05-06 17:53:37 +00009366- When __slots__ are set to a unicode string, make it work the same as
Neal Norwitzcbd9ee62007-04-14 05:25:50 +00009367 setting a plain string, ie don't expand to single letter identifiers.
9368
Raymond Hettinger13936692007-04-11 18:40:58 +00009369- Request #1191699: Slices can now be pickled.
9370
Raymond Hettinger4db5fe92007-04-12 04:10:00 +00009371- Request #1193128: str.translate() now allows a None argument for
9372 translations that only remove characters without re-mapping the
9373 remaining characters.
9374
Georg Brandl5cb76c12007-03-21 09:00:39 +00009375- Patch #1682205: a TypeError while unpacking an iterable is no longer
9376 masked by a generic one with the message "unpack non-sequence".
9377
Neal Norwitzaa754b72007-03-21 06:39:48 +00009378- Remove unused file Python/fmod.c.
9379
Guido van Rossum143b5642007-03-23 04:58:42 +00009380- Bug #1683368: The object.__init__() and object.__new__() methods are
9381 now stricter in rejecting excess arguments. The only time when
9382 either allows excess arguments is when it is not overridden and the
9383 other one is. For backwards compatibility, when both are
9384 overridden, it is a deprecation warning (for now; maybe a Py3k
Guido van Rossum234b1ff2007-03-23 19:39:01 +00009385 warning later). Also, type.__init__() insists on the same signature
9386 as supported by type.__new__().
Guido van Rossum143b5642007-03-23 04:58:42 +00009387
Georg Brandl3ee81df2008-05-17 18:14:43 +00009388- Patch #1675423: PyComplex_AsCComplex() now tries to convert an
9389 object to complex using its __complex__() method before falling back
9390 to the __float__() method. Therefore, the functions in the cmath
9391 module now can operate on objects that define a __complex__()

Georg Brandl4e933132006-09-06 20:05:58 +00009531- Bug #1542051: Exceptions now correctly call PyObject_GC_UnTrack.

Gregory P. Smithbde4ae42008-01-17 08:35:49 +000010357 that the SMTP.starttls() caller no longer needs to call ehlo()
10358 beforehand. SMTP.starttls() now raises an exception of the server
Georg Brandl3ee81df2008-05-17 18:14:43 +000010359 does not claim to support starttls. Adds the

Georg Brandl3ee81df2008-05-17 18:14:43 +000010459 time so that opening a database previously created with the DB_DUP
10460 or DB_DUPSORT flag set will keep the proper behavior on subsequent
10461 opens. Specifically: dictionary assignment to a DB object will
10462 replace all values for a given key when the database allows
10463 duplicate values. DB users should use DB.put(k, v) when they want
10464 to store duplicates; not DB[k] = v.

10471 characters with ASCII value less than 32. Also, it correctly quotes
10472 dots only if they occur on a single line, as opposed to the previous
10473 behavior of quoting dots if they are the second character of any
10474 line.

Georg Brandl3ee81df2008-05-17 18:14:43 +000010883- Removed the macfs module. It had been deprecated since Python 2.5.
10884 This lead to the deprecation of macostools.touched() as it relied
10885 solely on macfs and was a no-op under OS X.
