1178
1179- As of 2.7.8, the 32-bit-only installer will support OS X 10.5
1180 and later systems as is currently done for Python 3.x installers.
1181 For 2.7.7 only, we will provide three installers:
1182 the legacy deprecated 10.3+ 32-bit-only format;
1183 the newer 10.5+ 32-bit-only format;
1184 and the unchanged 10.6+ 64-/32-bit format.
1185 Although binary installers will no longer be available from
1186 python.org as of 2.7.8, it will still be possible to build from
1187 source on 10.3.9 and 10.4 systems if necessary.
1188 See Mac/BuildScript/README.txt for more information.

2570 32-bit-only installer Pythons on systems with Xcode 4 (currently
2571 OS X 10.8, 10.7, and optionally 10.6).
2572 * Backport 3.3.0 fixes to 2.7 branch (for release in 2.7.4)
2573 * Since Xcode 4 removes ppc support, extension module builds now
2574 check for ppc compiler support and by default remove ppc and
2575 ppc64 archs when they are not available.
2576 * Extension module builds now revert to using system installed
2577 headers and libs (/usr and /System/Library) if the SDK used
2578 to build the interpreter is not installed or has moved.
2579 * Try to avoid building extension modules with deprecated
2580 and problematic Apple llvm-gcc compiler. If original compiler
2581 is not available, use clang instead by default.

Florent Xiclunac2279652012-02-12 14:49:03 +01003018- Issue #13994: Earlier partial revert of Distutils enhancements in 2.7
Ned Deilyc47a4592012-02-11 20:40:24 +01003019 has left two versions of customize_compiler, the original in
3020 distutils.sysconfig and another copy in distutils.ccompiler, with some
3021 parts of distutils calling one and others using the other.
3022 Complete the revert back to only having one in distutils.sysconfig as
3023 is the case in 3.x.
3024
Ned Deily0d0ea482012-02-10 12:59:06 +01003025- Issue #13590: On OS X 10.7 and 10.6 with Xcode 4.2, building
3026 Distutils-based packages with C extension modules may fail because
3027 Apple has removed gcc-4.2, the version used to build python.org
3028 64-bit/32-bit Pythons. If the user does not explicitly override
3029 the default C compiler by setting the CC environment variable,
3030 Distutils will now attempt to compile extension modules with clang
3031 if gcc-4.2 is required but not found. Also as a convenience, if
3032 the user does explicitly set CC, substitute its value as the default
3033 compiler in the Distutils LDSHARED configuration variable for OS X.
3034 (Note, the python.org 32-bit-only Pythons use gcc-4.0 and the 10.4u
3035 SDK, neither of which are available in Xcode 4. This change does not
3036 attempt to override settings to support their use with Xcode 4.)

Ned Deily87e82bb2011-06-28 19:52:59 -07003286- Issue #9516: On Mac OS X, change Distutils to no longer globally attempt to
3287 check or set the MACOSX_DEPLOYMENT_TARGET environment variable for the
3288 interpreter process. This could cause failures in non-Distutils subprocesses
3289 and was unreliable since tests or user programs could modify the interpreter
Ezio Melotti302ad8d2013-01-19 19:44:58 +02003290 environment after Distutils set it. Instead, have Distutils set the
Ned Deily87e82bb2011-06-28 19:52:59 -07003291 deployment target only in the environment of each build subprocess. It is
3292 still possible to globally override the default by setting
3293 MACOSX_DEPLOYMENT_TARGET before launching the interpreter; its value must be
3294 greater or equal to the default value, the value with which the interpreter
3295 was built.

3324 updating the check interval, so if the user decreases the check interval,
3325 the ticker doesn't have to wind down to zero from the old starting point
3326 before the new interval takes effect. And if the user increases the
3327 interval, it makes sure the new limit takes effect right away rather have an
3328 early task switch before recognizing the new interval.

4326 This prevents user-created self-referencing ordered dictionaries from
4327 becoming permanently uncollectable GC garbage. The downside is that

4787
Ezio Melottiab2eb0e2010-06-05 19:21:32 +00004788- Issue #8271: during the decoding of an invalid UTF-8 byte sequence, only the
4789 start byte and the continuation byte(s) are now considered invalid, instead
4790 of the number of bytes specified by the start byte.
4791 E.g.: '\xf1\x80AB'.decode('utf-8', 'replace') now returns u'\ufffdAB' and
4792 replaces with U+FFFD only the start byte ('\xf1') and the continuation byte
4793 ('\x80') even if '\xf1' is the start byte of a 4-bytes sequence.
4794 Previous versions returned a single u'\ufffd'.

4798 arises from the "Overriding __eq__ blocks inheritance ..." warning
4799 when turned into an exception: in this case the exception simply
4800 gets ignored.

Mark Dickinson4ca7c3c2010-05-30 13:18:10 +00004802- Issue #8748: Fix two issues with comparisons between complex and integer
4803 objects. (1) The comparison could incorrectly return True in some cases
4804 (2**53+1 == complex(2**53) == 2**53), breaking transivity of equality.
4805 (2) The comparison raised an OverflowError for large integers, leading
4806 to unpredictable exceptions when combining integers and complex objects
4807 in sets or dicts.
4808
Mark Dickinson81336372010-05-30 12:12:25 +00004809- Issue #5211: Implicit coercion for the complex type is now completely
4810 removed. (Coercion for arithmetic operations was already removed in 2.7
4811 alpha 4, but coercion for rich comparisons was accidentally left in.)
4812
Victor Stinnerc49dfcc2010-05-25 22:30:32 +00004813- Issue #3798: Write sys.exit() message to sys.stderr to use stderr encoding

Georg Brandlfee0f442010-05-22 21:26:21 +00005000- Issue #8567: Fix precedence of signals in Decimal module: when a Decimal
5001 operation raises multiple signals and more than one of those signals is
5002 trapped, the specification determines the order in which the signals should be
5003 handled. In many cases this order wasn't being followed, leading to the wrong
5004 Python exception being raised.

5190 with a non-empty format string. This is an effort to future-proof user
5191 code. If a derived class does not currently implement __format__ but later
5192 adds its own __format__, it would most likely break user code that had

Georg Brandlfee0f442010-05-22 21:26:21 +00005244- Issue #7279: Comparisons involving a Decimal signaling NaN now signal
5245 InvalidOperation instead of returning False. (Comparisons involving a quiet
5246 NaN are unchanged.) Also, Decimal quiet NaNs are now hashable; Decimal
5247 signaling NaNs remain unhashable.

Georg Brandlfee0f442010-05-22 21:26:21 +00005249- Issue #2531: Comparison operations between floats and Decimal instances now
5250 return a result based on the numeric values of the operands; previously they
5251 returned an arbitrary result based on the relative ordering of id(float) and
5252 id(Decimal).

Barry Warsawf7f2d6f2010-03-31 21:07:16 +00005254- Issue #8233: When run as a script, py_compile.py optionally takes a single
Georg Brandlfee0f442010-05-22 21:26:21 +00005255 argument `-` which tells it to read files to compile from stdin. Each line is
5256 read on demand and the named file is compiled immediately. (Original patch by
5257 Piotr Ożarowski).

5267 Fractions instance now raise TypeError instead of returning True/False. This
5268 makes Fraction <=> complex comparisons consistent with int <=> complex, float
5269 <=> complex, and complex <=> complex comparisons.

Mark Dickinson4846a8e2010-04-03 14:05:10 +00005368- Issue #8300: When passing a non-integer argument to struct.pack with any
5369 integer format code, struct.pack first attempts to convert the non-integer

5372
Georg Brandlba83f822010-03-14 09:50:54 +00005373- Issue #1530559: When passing a non-integer argument to struct.pack with *any*
5374 integer format code (one of 'bBhHiIlLqQ'), struct.pack attempts to use the
5375 argument's __int__ method to convert to an integer before packing. It also
Georg Brandlfee0f442010-05-22 21:26:21 +00005376 produces a DeprecationWarning in this case. (In Python 2.6, the behaviour was
5377 inconsistent: __int__ was used for some integer codes but not for others, and
5378 the set of integer codes for which it was used differed between native packing
5379 and standard packing.)

Georg Brandlba83f822010-03-14 09:50:54 +00005786- The ``__complex__()`` method is now looked up on the class of instances to
5787 make it consistent with other special methods.

5791
Mark Dickinson1b34d252010-01-01 17:27:30 +00005792- Issue #5080: A number of functions and methods previously produced a
Georg Brandlba83f822010-03-14 09:50:54 +00005793 DeprecationWarning when passed a float argument where an integer was expected.
5794 These functions and methods now raise TypeError instead. The majority of the
5795 effects of this change are in the extension modules, but some core functions
5796 and methods are affected: notably the 'chr', 'range' and 'xrange' builtins,
5797 and many unicode/str methods.

Georg Brandlba83f822010-03-14 09:50:54 +00005961- Issue #3382: 'F' formatting for float and complex now convert the result to
5962 upper case. This only affects 'inf' and 'nan', since 'f' no longer converts
5963 to 'g' for large values.
Amaury Forgeot d'Arcd7288712009-12-01 21:51:04 +00005964
Georg Brandlba83f822010-03-14 09:50:54 +00005965- Remove switch from "%f" formatting to "%g" formatting for floats larger than
5966 1e50 in absolute value.
Mark Dickinson9dd5e162009-11-23 20:54:09 +00005967
Georg Brandlba83f822010-03-14 09:50:54 +00005968- Remove restrictions on precision when formatting floats. E.g., "%.120g" %
5969 1e-100 used to raise OverflowError, but now gives the requested 120
5970 significant digits instead.
Mark Dickinson18cfada2009-11-23 18:46:41 +00005971
Georg Brandlba83f822010-03-14 09:50:54 +00005972- Add Py3k warnings for parameter names in parentheses.

5977 10.6.
Ronald Oussoren315cd0c2009-11-19 16:25:21 +00005978
Georg Brandlba83f822010-03-14 09:50:54 +00005979- Issue #7117: ``repr(x)`` for a float x returns a result based on the shortest
5980 decimal string that's guaranteed to round back to x under correct rounding
5981 (with round-half-to-even rounding mode). Previously it gave a string based on
5982 rounding x to 17 decimal digits. repr(x) for a complex number behaves
5983 similarly. On platforms where the correctly-rounded strtod and dtoa code is
5984 not supported (see below), repr is unchanged.
Mark Dickinsonb678de82009-11-19 18:41:49 +00005985
Georg Brandlba83f822010-03-14 09:50:54 +00005986- Issue #7117: On almost all platforms: float-to-string and string-to-float
5987 conversions within Python are now correctly rounded. Places these conversions
5988 occur include: str for floats and complex numbers; the float and complex
5989 constructors; old-style and new-style numeric formatting; serialization and
5990 deserialization of floats and complex numbers using marshal, pickle and json;
5991 parsing of float and imaginary literals in Python code; Decimal-to-float
5992 conversion.
Mark Dickinsonb678de82009-11-19 18:41:49 +00005993
Georg Brandlba83f822010-03-14 09:50:54 +00005994 The conversions use a Python-adapted version of David Gay's well-known dtoa.c,
5995 providing correctly-rounded strtod and dtoa C functions. This code is
5996 supported on Windows, and on Unix-like platforms using gcc, icc or suncc as
5997 the C compiler. There may be a small number of platforms on which correct
5998 operation of this code cannot be guaranteed, so the code is not used: notably,
5999 this applies to platforms where the C double format is not IEEE 754 binary64,
6000 and to platforms on x86 hardware where the x87 FPU is set to 64-bit precision
6001 and Python's configure script is unable to determine how to change the FPU
6002 precision. On these platforms conversions use the platform strtod and dtoa,
6003 as before.
Mark Dickinsonb678de82009-11-19 18:41:49 +00006004
Georg Brandlba83f822010-03-14 09:50:54 +00006005- Issue #7117: Backport round implementation from Python 3.x. ``round()`` now
6006 uses the correctly-rounded string <-> float conversions described above (when
6007 available), and so produces correctly rounded results that will display nicely
6008 under the float repr. There are two related small changes: (1) round now
6009 accepts any class with an ``__index__()`` method for its second argument (but
6010 no longer accepts floats for the second argument), and (2) an excessively
6011 large second integer argument (e.g., ``round(1.234, 10**100)``) no longer
6012 raises an exception.

6015
Georg Brandlba83f822010-03-14 09:50:54 +00006016- Fix several issues with ``compile()``. The input can now contain Windows and

6048 The tables for code points representing numeric values, white spaces or line
6049 breaks are now generated from the official Unicode Character Database files,
6050 and include information from the Unihan.txt file.

Georg Brandlba83f822010-03-14 09:50:54 +00006159- Issue #5920: For ``float.__format__()``, change the behavior with the empty
6160 presentation type (that is, not one of 'e', 'f', 'g', or 'n') to be like 'g'
6161 but with at least one decimal point and with a default precision
6162 of 12. Previously, the behavior the same but with a default precision of 6.
6163 This more closely matches ``str()``, and reduces surprises when adding
6164 alignment flags to the empty presentation type. This also affects the new
6165 complex.__format__ in the same way.

Georg Brandlba83f822010-03-14 09:50:54 +00007675 leak-chasing test runs give sensible results. The previous method of reaping
7676 threads could return successfully while some Thread objects were still
7677 referenced. This also introduces a new private function: ``thread._count()``.

7816
Martin v. Löwis9fa5a282008-09-11 06:53:30 +00007817- Issue #3642: Suppress warning in obmalloc when size_t is larger than uint.
7818
Amaury Forgeot d'Arc05e34492008-09-10 22:04:45 +00007819- Issue #3743: In a few places, PY_FORMAT_SIZE_T was incorrectly used with
7820 PyString_FromFormat or PyErr_Format to display size_t values. The macro
7821 PY_FORMAT_SIZE_T is designed to select the correct format for the OS
7822 ``printf`` function, whereas PyString_FromFormat has an independent
7823 implementation and uses "%zd" on all platforms for size_t values.
7824 This makes a difference on win64, where ``printf`` needs "%Id" to display
7825 64bit values.
7826
Benjamin Peterson97179b02008-09-09 20:55:01 +00007827- Issue #3634: _weakref.ref(Exception).__init__() gave invalid return value on
7828 error.
7829
Amaury Forgeot d'Arcd3ffb892008-09-09 07:24:30 +00007830- Issue #3777: long() applied to a float object now always return a long
7831 object; previously an int would be returned for small values. the __long__
7832 method is allowed to return either an int or a long, but the behaviour of
7833 float objects should not change to respect backward compatibility.
7834
Amaury Forgeot d'Arc3571fbf2008-09-01 19:52:00 +00007835- Issue #3751: str.rpartition would perform a left-partition when called with
7836 a unicode argument.
7837
Benjamin Peterson17f03ca2008-09-01 14:18:30 +00007838- Issue #3683: Fix compilation when --without-threads is given.
7839
Antoine Pitroud4ae97b2008-08-29 18:39:48 +00007840- Issue #3668: Fix a memory leak with the "s*" argument parser in
Vinay Sajip35e3b032008-09-01 14:33:59 +00007841 PyArg_ParseTuple and friends, which occurred when the argument for "s*"
Antoine Pitroud4ae97b2008-08-29 18:39:48 +00007842 was correctly parsed but parsing of subsequent arguments failed.
7843
Vinay Sajip35e3b032008-09-01 14:33:59 +00007844- Issue #2534: speed up isinstance() and issubclass() by 50-70%, so as to
Antoine Pitrou0668c622008-08-26 22:42:08 +00007845 match Python 2.5 speed despite the __instancecheck__ / __subclasscheck__
7846 mechanism. In the process, fix a bug where isinstance() and issubclass(),
7847 when given a tuple of classes as second argument, were looking up
7848 __instancecheck__ / __subclasscheck__ on the tuple rather than on each
7849 type object.
7850
Neal Norwitz18aa3882008-08-24 05:04:52 +00007851- Fix crashes on memory allocation failure found with failmalloc.
7852
7853- Fix memory leaks found with valgrind and update suppressions file.
7854
7855- Fix compiler warnings in opt mode which would lead to invalid memory reads.
7856
7857- Fix problem using wrong name in decimal module reported by pychecker.
7858
Christian Heimes7d4c3172008-08-22 19:47:25 +00007859- Silenced another compiler warning about a used but not defined
7860 function 'stringlib_contains_obj'.

7863 ``__delslice__``.
7864
Gregory P. Smith2bb25cc2008-09-02 05:29:51 +00007865- Issue #3678: Correctly pass LDFLAGS and LDLAST to the linker on shared
7866 library targets in the Makefile.
7867
Gregory P. Smith980b99b2008-09-07 05:15:18 +00007868- Issue #1204: The configure script now tests for additional libraries
7869 that may be required when linking against readline. This fixes issues
7870 with x86_64 builds on some platforms (a few Linux flavors and OpenBSD).

Brett Cannon1eaf0742008-09-02 01:25:16 +00007920 warnings.catch_warnings() along with some API cleanup. Expanding the tests
7921 for catch_warnings() also led to an improvement in the raising of a
7922 DeprecationWarning related to warnings.warn_explicit().
7923
Benjamin Peterson973e6c22008-09-01 23:12:58 +00007924- The deprecation warnings for the old camelCase threading API were removed.

Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00007988What's New in Python 2.6 beta 3?
7989================================
7990
Barry Warsaw07a4a382008-08-21 01:15:08 +00007991*Release date: 20-Aug-2008*
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00007992
7993Core and Builtins
7994-----------------
7995
Guido van Rossumf8402962008-08-20 15:01:50 +00007996- Issue #1878: Remove Py_TPFLAGS_HAVE_VERSION_TAG from
7997 Py_TPFLAGS_DEFAULT when not building the core. This means 3rd party
7998 extensions do not automatically benefit from the class attribute
7999 cache; they will have to explicitly add Py_TPFLAGS_HAVE_VERSION_TAG
8000 to their tp_flags field if they care. This is a backwards
8001 compatibility feature; in 3.0, all types will use the cache by
8002 default.
8003
Benjamin Petersonf647dc12008-08-20 01:27:30 +00008004- Keyword arguments can now follow starred arguments. (``f(a, *args,
8005 keyword=23)`` is now valid syntax.)
8006
Thomas Heller0ad5ae02008-08-19 19:25:04 +00008007- ctypes function pointers that are COM methods have a boolean True
8008 value again.
8009
Martin v. Löwisf91d46a2008-08-12 14:49:50 +00008010- Issue #3139: Make buffer-interface thread-safe wrt. PyArg_ParseTuple,
8011 by denying s# to parse objects that have a releasebuffer procedure,
8012 and introducing s*.
8013
Georg Brandl1e13ea92008-08-11 09:07:59 +00008014- Issue #3537: Fix an assertion failure when an empty but presized dict
8015 object was stored in the freelist.
8016
Mark Dickinsonb6467572008-08-04 21:30:09 +00008017- Issue #1481296: Make long(float('nan')) and int(float('nan')) raise
8018 ValueError consistently across platforms.
8019
Amaury Forgeot d'Arc39fd6722008-07-31 21:28:03 +00008020- Issue #3479: On platforms where sizeof(int) is smaller than sizeof(long)
8021 (64bit Unix, for example), unichr() would truncate its argument and return
8022 u'\x00' for unichr(2**32). Now it properly raises an OverflowError.
8023
Neal Norwitze7d8be82008-07-31 17:17:14 +00008024- Apply security patches from Apple.
8025
Amaury Forgeot d'Arc246daed2008-07-31 00:42:16 +00008026- Issue #2542: Now that issubclass() may call arbitrary code, ensure that
8027 PyErr_ExceptionMatches returns 0 when an exception occurs there.
8028
Antoine Pitrou92f82162008-07-25 22:22:08 +00008029- Issue #1819: function calls with several named parameters are now on
8030 average 35% faster (as measured by pybench).
8031
Amaury Forgeot d'Arce4921fe2008-07-21 22:00:38 +00008032- Issue #2378: An unexpected UnboundLocalError or NameError could appear when
8033 the python debugger steps into a class statement: the free variables (local
8034 variables defined in an outer scope) would be deleted from the outer scope.
8035
Gregory P. Smith0470bab2008-07-22 04:46:32 +00008036- Issue #2620: Overflow checking when allocating or reallocating memory
8037 was not always being done properly in some python types and extension
8038 modules. PyMem_MALLOC, PyMem_REALLOC, PyMem_NEW and PyMem_RESIZE have
8039 all been updated to perform better checks and places in the code that
8040 would previously leak memory on the error path when such an allocation
8041 failed have been fixed.

8047
Benjamin Petersone977ad42008-08-20 01:42:01 +00008048- The methods ``is_in_tuple()``, ``is_vararg()``, and ``is_keywordarg()`` of
8049 symtable.Symbol have been deprecated for removal in 3.0 and the next release.
8050
Amaury Forgeot d'Arc351ffb82008-08-18 19:23:47 +00008051- Issue #2234: distutils failed for some versions of the cygwin compiler. The
8052 version reported by these tools does not necessarily follow the python
8053 version numbering scheme, so the module is less strict when parsing it.
8054
Nick Coghlanf70385a2008-08-18 12:42:46 +00008055- Issue #2235: Added Py3k warnings for types which will become unhashable
8056 under the stricter __hash__ inheritance rules in 3.0. Several types
8057 which did not meet the rules for hash invariants and were already
8058 unhashable in 3.0 have now been explicitly flagged as unhashable in
8059 2.6 as well (collections.Mapping, collections.Set, unittest.TestSuite,
8060 xml.dom.minidom.NamedNodeMap, numbers.Number, UserList.UserList)
8061
Brett Cannon88f801d2008-08-18 00:46:22 +00008062- Update __all__ for cookielib, csv, os, urllib2, and weakref to include things
8063 imported into the module but exposed as part of the module's API.
8064
Brett Cannon7b96f072008-08-18 00:41:11 +00008065- Remove an unneeded import of abc.ABCMeta from 'inspect'.

Brett Cannon25c9d6a2008-08-17 22:10:11 +00008069- Remove unneeded imports of 'warnings' from shelve, filecmp, and dummy_thread.
8070
Hirokazu Yamamoto41a81eb2008-08-17 13:10:46 +00008071- Issue #3575: Incremental decoder's decode function now takes bytearray
8072 by using 's*' instead of 't#'.
8073
Mark Dickinson3e4caeb2009-02-21 20:27:01 +00008074- Issue #2222: Fixed reference leak when occurred os.rename()
Hirokazu Yamamoto7f30a682008-08-17 09:46:56 +00008075 fails unicode conversion on 2nd parameter. (windows only)
8076
Georg Brandl222e2082010-08-01 22:27:39 +00008077- Issue #2464: urllib2 now supports a malformation in the URL received

Antoine Pitroude781a42008-08-09 12:43:23 +00008131 asking for a specific length. This problem only affected files opened

8175
Nick Coghlan2a0c2b12008-08-04 12:47:17 +00008176- Issue #643841: The language reference now provides more detailed

8189
Georg Brandl3e483f62008-07-16 22:57:41 +00008190- Issue #3156: Fix inconsistent behavior of the bytearray type: all
8191 its methods now allow for items objects that can be converted to
8192 an integer using operator.index().
8193
Mark Dickinson64b7e502008-07-16 09:40:03 +00008194- Issue #3360: Fix incorrect parsing of '020000000000.0', which
8195 produced a ValueError instead of giving the correct float.
8196
Eric Smitha5fa5a22008-07-16 00:11:49 +00008197- Issue #3083: Add alternate (#) formatting for bin, oct, hex output
8198 for str.format(). This adds the prefix 0b, 0o, or 0x, respectively.
8199
Mark Dickinson7103aa42008-07-15 19:08:33 +00008200- Issue #3008: the float type has a new instance method 'float.hex'
8201 and a new class method 'float.fromhex' to convert floating-point
8202 numbers to and from hexadecimal strings, respectively.
8203
Nick Coghlan6d6bd442008-07-15 15:40:22 +00008204- Issue #2235: __hash__ is once again inherited by default. To allow
8205 collections.Hashable to remain meaningful in the presence of the
8206 default hash implementation (object.__hash__), it is now possible
8207 to explicit block inheritance of hash by setting __hash__=None at
8208 the Python level, or tp_hash=PyObject_HashNotImplemented at the C
8209 level.
8210
Nick Coghlanb028f502008-07-13 14:52:36 +00008211- Issue #3221: Issue a RuntimeWarning instead of raising SystemError if
8212 the parent module cannot be found while performing an absolute import.
8213 This means that an incorrectly defined __package__ attribute will
8214 now only prevent relative imports in that module rather than causing
8215 all imports from that module to fail.
8216
Nick Coghlan14ff9942008-07-08 14:21:42 +00008217- Issue #2517: Allow unicode messages in Exceptions again by correctly

8227 another thread's dictionary.
8228
Mark Dickinson1ec2fcd2008-06-20 14:53:43 +00008229- Issue #3004: Minor change to slice.indices(): the start and stop
8230 arguments are now treated identically, making the behaviour easier
8231 to describe and understand. For example, slice(None, -10,
8232 1).indices(9) now returns (0, 0, 1) instead of (0, -1, 1), and
8233 slice(None, 10, -1).indices(10) returns (9, 9, -1) instead of (9,
8234 10, -1).

Georg Brandl278fc502008-07-19 12:46:12 +00008236- Issue #3219: Calling a function with repeated keyword arguments,

8277 both unnecessary (HTTP allows text content to be sent in several forms) and
Andrew M. Kuchlingcc3f2b12008-07-10 14:43:31 +00008278 wrong because the actual transmitted size could differ from the
Amaury Forgeot d'Arc0f7cddc2008-07-06 21:34:39 +00008279 content-length. The problem had been corrected in the 2.4 branch, but never

8683
Ronald Oussoren5640ce22008-06-05 12:58:24 +00008684- On MacOS X it is now possible to install the framework in 64-bit
8685 mode or even as a 4-way universal binary (that is, PPC, i386,
Georg Brandl5cc774e2008-06-11 20:28:06 +00008686 PPC64 and x86_64 support in one binary).
Ronald Oussoren5640ce22008-06-05 12:58:24 +00008687
8688 This is controlled by the configure argument ``--with-universal-archs``:
8689
8690 - ``--with-universal-archs=all``: install 4-way universal
8691
8692 - ``--with-universal-archs=32-bit``: install 2-way universal, 32-bit (the default)
8693
8694 - ``--with-universal-archs=64-bit``: install 2-way universal, 64-bit
8695
8696 This option should be used in combination with ``--enable-universalsdk=``.
8697
8698 NOTE: 64-bit and 4-way builds are only suppported on Mac OS X 10.5 (or later).

Georg Brandl3ee81df2008-05-17 18:14:43 +00008747- Issue #1631171: Re-implement the 'warnings' module in C (the
8748 original Python code has been kept as backup). This will allow for
8749 using the 'warning's machinery in such places as the parser where
8750 use of pure Python code is not possible. Both the ``showarning()``
8751 and ``formatwarning()`` gain an optional 'line' argument which is
8752 not called by default for backwards-compatibility reasons. Setting
8753 ``warnings.showwarning()`` to an implementation that lacks support
8754 for the ``line`` argument will raise a DeprecationWarning.

Georg Brandl3ee81df2008-05-17 18:14:43 +00008796- Issue #2513: distutils on Windows is now capable of cross-compiling
Mark Hammond495cf992008-04-07 01:53:39 +00008797 extension modules between 32 and 64 bit platforms. See the distutls

Georg Brandl3ee81df2008-05-17 18:14:43 +00008817- Issue #2550: The approach used by client/server code for obtaining
8818 ports to listen on in network-oriented tests has been refined in an
8819 effort to facilitate running multiple instances of the entire
8820 regression test suite in parallel without issue.
8821 test_support.bind_port() has been fixed such that it will always
8822 return a unique port -- which wasn't always the case with the
8823 previous implementation, especially if socket options had been set
8824 that affected address reuse (i.e. SO_REUSEADDR, SO_REUSEPORT). The
8825 new implementation of bind_port() will actually raise an exception
8826 if it is passed an AF_INET/SOCK_STREAM socket with either the
8827 SO_REUSEADDR or SO_REUSEPORT socket option set. Furthermore, if
8828 available, bind_port() will set the SO_EXCLUSIVEADDRUSE option on
8829 the socket it's been passed. This currently only applies to
8830 Windows. This option prevents any other sockets from binding to the
8831 host/port we've bound to, thus removing the possibility of the
8832 'non-deterministic' behaviour, as Microsoft puts it, that occurs
8833 when a second SOCK_STREAM socket binds and accepts to a host/port
8834 that's already been bound by another socket. The optional preferred
8835 port parameter to bind_port() has been removed. Under no
8836 circumstances should tests be hard coding ports!
8837
8838 test_support.find_unused_port() has also been introduced, which will
8839 pass a temporary socket object to bind_port() in order to obtain an
8840 unused port. The temporary socket object is then closed and
8841 deleted, and the port is returned. This method should only be used
8842 for obtaining an unused port in order to pass to an external program
8843 (i.e. the -accept [port] argument to openssl's s_server mode) or as
8844 a parameter to a server-oriented class that doesn't give you direct
8845 access to the underlying socket used.
8846
8847 Finally, test_support.HOST has been introduced, which should be used
8848 for the host argument of any relevant socket calls (i.e. bind and
8849 connect).
Trent Nelsone41b0062008-04-08 23:47:30 +00008850
8851 The following tests were updated to following the new conventions:
Georg Brandl3ee81df2008-05-17 18:14:43 +00008852 test_socket, test_smtplib, test_asyncore, test_ssl, test_httplib,
Trent Nelsone41b0062008-04-08 23:47:30 +00008853 test_poplib, test_ftplib, test_telnetlib, test_socketserver,
8854 test_asynchat and test_socket_ssl.
8855
Georg Brandl3ee81df2008-05-17 18:14:43 +00008856 It is now possible for multiple instances of the regression test
8857 suite to run in parallel without issue.

Eric Smitha73fbe72008-02-23 03:09:44 +00009136- Added the future_builtins module, which contains hex() and oct().
9137 These are the PEP 3127 version of these functions, designed to be
9138 compatible with the hex() and oct() builtins from Python 3.0. They
9139 differ slightly in their output formats from the existing, unchanged
9140 Python 2.6 builtins. The expected usage of the future_builtins
9141 module is:
9142 from future_builtins import hex, oct
9143
Eric Smith7ef40bf2008-02-20 23:34:22 +00009144- Issue #1600: Modifed PyOS_ascii_formatd to use at most 2 digit
9145 exponents for exponents with absolute value < 100. Follows C99
9146 standard. This is a change on Windows, which would use 3 digits.
9147 Also, added 'n' to the formats that PyOS_ascii_formatd understands,
9148 so that any alterations it does to the resulting string will be
9149 available in stringlib/formatter.h (for float.__format__).
9150
Eric Smith5a3c1352008-02-19 13:21:56 +00009151- Implemented PEP 3101, Advanced String Formatting. This adds a new
9152 builtin format(); a format() method for str and unicode; a
9153 __format__() method to object, str, unicode, int, long, float, and
9154 datetime; the class string.Formatter; and the C API
9155 PyObject_Format().
9156
Georg Brandl3ee81df2008-05-17 18:14:43 +00009157- Fixed several potential crashes, all caused by specially crafted
9158 __del__ methods exploiting objects in temporarily inconsistent
9159 state.

Georg Brandl3ee81df2008-05-17 18:14:43 +00009165- Fixed repr() and str() of complex numbers with infinity or nan as
9166 real or imaginary part.
Christian Heimes2f0da532008-02-15 06:57:08 +00009167
Georg Brandl3ee81df2008-05-17 18:14:43 +00009168- Clear all free lists during a gc.collect() of the highest generation
9169 in order to allow pymalloc to free more arenas. Python may give back
9170 memory to the OS earlier.
Christian Heimes3b718a72008-02-14 12:47:33 +00009171
Georg Brandl3ee81df2008-05-17 18:14:43 +00009172- Issue #2045: Fix an infinite recursion triggered when printing a
9173 subclass of collections.defaultdict, if its default_factory is set
9174 to a bound method.
Amaury Forgeot d'Arcb01aa432008-02-08 00:56:02 +00009175
Christian Heimesf75dbef2008-02-08 00:11:31 +00009176- Fixed a minor memory leak in dictobject.c. The content of the free
9177 list was not freed on interpreter shutdown.
9178
Georg Brandl21e99f42010-03-07 15:23:59 +00009179- Limit free list of method and built-in function objects to 256
Georg Brandl3ee81df2008-05-17 18:14:43 +00009180 entries each.
Christian Heimes6075a822008-02-06 12:44:34 +00009181
Georg Brandl3ee81df2008-05-17 18:14:43 +00009182- Patch #1953: Added ``sys._compact_freelists()`` and the C API
9183 functions ``PyInt_CompactFreeList`` and ``PyFloat_CompactFreeList``
Christian Heimes422051a2008-02-04 18:00:12 +00009184 to compact the internal free lists of pre-allocted ints and floats.
9185
Georg Brandl3ee81df2008-05-17 18:14:43 +00009186- Issue #1983: Fixed return type of fork(), fork1() and forkpty()
9187 calls. Python expected the return type int but the fork familie
9188 returns pi_t.
Christian Heimes951cc0f2008-01-31 23:08:23 +00009189
Georg Brandl3ee81df2008-05-17 18:14:43 +00009190- Issue #1678380: Fix a bug that identifies 0j and -0j when they
9191 appear in the same code unit.
Mark Dickinson105be772008-01-31 22:17:37 +00009192

Georg Brandl3ee81df2008-05-17 18:14:43 +00009202- Patch #1473257: generator objects gain a gi_code attribute. This is
9203 the same object as the func_code attribute of the function that
9204 produced the generator.
Georg Brandl0cdf9a32008-01-26 14:14:20 +00009205
Georg Brandl3ee81df2008-05-17 18:14:43 +00009206- Issue #1920: "while 0" statements were completely removed by the
9207 compiler, even in the presence of an "else" clause, which is
9208 supposed to be run when the condition is false. Now the compiler
9209 correctly emits bytecode for the "else" suite.
Amaury Forgeot d'Arc31eaafe2008-01-24 22:59:25 +00009210
Guido van Rossumeead05f2008-01-24 18:21:02 +00009211- A few crashers fixed: weakref_in_del.py (issue #1377858);
9212 loosing_dict_ref.py (issue #1303614, test67.py);
9213 borrowed_ref_[34].py (not in tracker).
9214
Vinay Sajipd7cf32e2008-01-24 12:43:33 +00009215- Issue #1069410: The "can't load dll" message box on Windows is
Christian Heimesb2302ba2008-01-23 17:15:06 +00009216 suppressed while an extension is loaded by calling SetErrorMode in
9217 dynload_win.c. The error is still reported properly.
9218
Georg Brandl3ee81df2008-05-17 18:14:43 +00009219- Issue #1915: Python compiles with --enable-unicode=no again. However
Christian Heimes082c9b02008-01-23 14:20:50 +00009220 several extension methods and modules do not work without unicode
9221 support.
9222
Georg Brandl26543b12008-01-21 18:36:51 +00009223- Issue #1882: when compiling code from a string, encoding cookies in the
9224 second line of code were not always recognized correctly.
9225
Georg Brandl14404b62008-01-19 19:27:05 +00009226- Issue #1679: "0x" was taken as a valid integer literal.
9227
Georg Brandl6caad7d2008-01-26 14:19:22 +00009228- Issue #1865: ``bytes`` as an alias for ``str`` and b"" as an alias "" were
Christian Heimes288e89a2008-01-18 18:24:07 +00009229 added.
9230
Christian Heimesc94e2b52008-01-14 04:13:37 +00009231- sys.float_info / PyFloat_GetInfo: The floating point information
9232 object was converted from a dict to a specialized structseq object.
9233
Georg Brandl3ee81df2008-05-17 18:14:43 +00009234- Patch #1816: Added sys.flags structseq. It exposes the status of
9235 most command line arguments and PYTHON* environment variables.
Christian Heimesf31b69f2008-01-14 03:42:48 +00009236
Georg Brandl3ee81df2008-05-17 18:14:43 +00009237- Objects/structseq.c: Implemented new structseq representation. The
9238 patch makes structseqs (e.g. the return value of os.stat) more
9239 readable.
Christian Heimes9c201962008-01-14 03:33:52 +00009240
Georg Brandl3ee81df2008-05-17 18:14:43 +00009241- Patch #1700288: added a type attribute cache that caches method
9242 accesses, resulting in speedups in heavily object-oriented code.
Amaury Forgeot d'Arce4c270c2008-01-14 00:29:41 +00009243
Neal Norwitz3fc15b82008-01-10 05:42:58 +00009244- Bug #1776: __import__() no longer accepts filenames on any platform.
9245 The first parameter to __import__() must be a valid module name.
Christian Heimes3403f152008-01-09 19:56:33 +00009246
Georg Brandlaed6c662008-01-07 17:25:53 +00009247- Patch #1668: renamed THREADDEBUG envvar to PYTHONTHREADDEBUG.
9248
Georg Brandl3ee81df2008-05-17 18:14:43 +00009249- Patch #602345: Add -B command line option, PYTHONDONTWRITEBYTECODE
9250 envvar and sys.dont_write_bytecode attribute. All these can be set
9251 to forbid Python to attempt to write compiled bytecode files.
Georg Brandl2da0fce2008-01-07 17:09:35 +00009252
Georg Brandl3ee81df2008-05-17 18:14:43 +00009253- Improve some exception messages when Windows fails to load an
9254 extension module. Now we get for example '%1 is not a valid Win32
9255 application' instead of 'error code 193'.
Amaury Forgeot d'Arce0b76952008-01-04 02:04:15 +00009256

9260 y) functions.
Christian Heimese2ca4242008-01-03 20:23:15 +00009261
Christian Heimes0a8143f2007-12-18 23:22:54 +00009262- Issue #1635: Platform independent creation and representation of NaN
Georg Brandl3ee81df2008-05-17 18:14:43 +00009263 and INF. float("nan"), float("inf") and float("-inf") now work on
9264 every platform with IEEE 754 semantics.
Christian Heimes0a8143f2007-12-18 23:22:54 +00009265
Georg Brandl3ee81df2008-05-17 18:14:43 +00009266- Compiler now generates simpler and faster code for dictionary
9267 literals. The oparg for BUILD_MAP now indicates an estimated
9268 dictionary size. There is a new opcode, STORE_MAP, for adding
9269 entries to the dictionary.

Georg Brandl3ee81df2008-05-17 18:14:43 +00009298- Patch #1739468: Directories and zipfiles containing a __main__.py
9299 file can now be directly executed by passing their name to the
9300 interpreter. The directory/zipfile is automatically inserted as the
9301 first entry in sys.path.
Nick Coghlan327a39b2007-11-18 11:56:28 +00009302
Georg Brandl3ee81df2008-05-17 18:14:43 +00009303- Issue #1265: Fix a problem with sys.settrace, if the tracing
9304 function uses a generator expression when at the same time the
9305 executed code is closing a paused generator.
Amaury Forgeot d'Arc0d75f092007-11-13 21:54:28 +00009306
Raymond Hettinger1760c8a2007-11-08 02:52:43 +00009307- sets and frozensets now have an isdisjoint() method.
9308
Raymond Hettinger3f8caa32007-10-24 01:28:33 +00009309- optimize the performance of builtin.sum().
9310
Neal Norwitz44f326e2007-10-05 05:29:17 +00009311- Fix warnings found by the new version of the Coverity checker.
9312
Georg Brandl21e99f42010-03-07 15:23:59 +00009313- The enumerate() built-in function is no longer bounded to sequences
Georg Brandl3ee81df2008-05-17 18:14:43 +00009314 smaller than LONG_MAX. Formerly, it raised an OverflowError. Now,
9315 automatically shifts from ints to longs.
Raymond Hettinger8f669372007-10-03 21:18:11 +00009316
Georg Brandl3ee81df2008-05-17 18:14:43 +00009317- Issue #1686386: Tuple's tp_repr did not take into account the
9318 possibility of having a self-referential tuple, which is possible
9319 from C code. Nor did object's tp_str consider that a type's tp_str
9320 could do something that could lead to an inifinite recursion.
9321 Py_ReprEnter() and Py_EnterRecursiveCall(), respectively, fixed the
9322 issues.
Brett Cannon0b14f242007-09-30 19:45:10 +00009323
Georg Brandl3ee81df2008-05-17 18:14:43 +00009324- Issue #1164: It was possible to trigger deadlock when using the
9325 'print' statement to write to a file since the GIL was not released
9326 as needed. Now PyObject_Print() does the right thing along with
9327 various tp_print implementations of the built-in types and those in
9328 the collections module.
Brett Cannon01531592007-09-17 03:28:34 +00009329
Georg Brandl3ee81df2008-05-17 18:14:43 +00009330- Issue #1147: Exceptions were directly allowing string exceptions in
9331 their throw() method even though string exceptions no longer
9332 allowed.
Brett Cannon4c20bc42007-09-11 21:02:28 +00009333
Georg Brandl3ee81df2008-05-17 18:14:43 +00009334- Issue #1096: Prevent a segfault from getting the repr of a very
9335 deeply nested list by using the recursion counter.
Brett Cannona0c05512007-09-10 21:38:27 +00009336
Brett Cannon1e534b52007-09-07 04:18:30 +00009337- Issue #1202533: Fix infinite recursion calls triggered by calls to
Georg Brandl3ee81df2008-05-17 18:14:43 +00009338 PyObject_Call() never calling back out to Python code to trigger
9339 recursion depth updates/checks. Required the creation of a static
9340 RuntimeError instance in case normalizing an exception put the
9341 recursion check value past its limit. Fixes crashers
9342 infinite_rec_(1|2|4|5).py.
Brett Cannon1e534b52007-09-07 04:18:30 +00009343
Georg Brandl3ee81df2008-05-17 18:14:43 +00009344- Patch #1031213: Decode source line in SyntaxErrors back to its

Neal Norwitz0ac60192007-05-27 04:08:54 +00009357- Add new attribute names for function objects. All the func_* become
Georg Brandl3ee81df2008-05-17 18:14:43 +00009358 __*__ attributes. (Some already existed, e.g., __doc__ and
9359 __name__.)
Neal Norwitz0ac60192007-05-27 04:08:54 +00009360
Neal Norwitz8b2bfbc2007-05-23 06:35:32 +00009361- Add -3 option to the interpreter to warn about features that are
9362 deprecated and will be changed/removed in Python 3.0.
9363
Georg Brandl2134e752007-05-21 20:34:16 +00009364- Patch #1686487: you can now pass any mapping after '**' in function
9365 calls.
9366
Collin Winter62903052007-05-18 23:11:24 +00009367- except clauses may now be spelled either "except E, target:" or
Georg Brandl3ee81df2008-05-17 18:14:43 +00009368 "except E as target:". This is to provide forwards compatibility
9369 with Python 3.0.

Brett Cannon229cee22007-05-05 01:34:02 +00009371- Deprecate BaseException.message as per PEP 352.
9372
Georg Brandl3ee81df2008-05-17 18:14:43 +00009373- Issue #1303614: don't expose object's __dict__ when the dict is
Georg Brandl21e99f42010-03-07 15:23:59 +00009374 inherited from a built-in base.

Vinay Sajip8549ce32007-05-06 17:53:37 +00009376- When __slots__ are set to a unicode string, make it work the same as
Neal Norwitzcbd9ee62007-04-14 05:25:50 +00009377 setting a plain string, ie don't expand to single letter identifiers.
9378
Raymond Hettinger13936692007-04-11 18:40:58 +00009379- Request #1191699: Slices can now be pickled.
9380
Raymond Hettinger4db5fe92007-04-12 04:10:00 +00009381- Request #1193128: str.translate() now allows a None argument for
9382 translations that only remove characters without re-mapping the
9383 remaining characters.
9384
Georg Brandl5cb76c12007-03-21 09:00:39 +00009385- Patch #1682205: a TypeError while unpacking an iterable is no longer
9386 masked by a generic one with the message "unpack non-sequence".
9387
Neal Norwitzaa754b72007-03-21 06:39:48 +00009388- Remove unused file Python/fmod.c.
9389
Guido van Rossum143b5642007-03-23 04:58:42 +00009390- Bug #1683368: The object.__init__() and object.__new__() methods are
9391 now stricter in rejecting excess arguments. The only time when
9392 either allows excess arguments is when it is not overridden and the
9393 other one is. For backwards compatibility, when both are
9394 overridden, it is a deprecation warning (for now; maybe a Py3k
Guido van Rossum234b1ff2007-03-23 19:39:01 +00009395 warning later). Also, type.__init__() insists on the same signature
9396 as supported by type.__new__().

Georg Brandl3ee81df2008-05-17 18:14:43 +00009398- Patch #1675423: PyComplex_AsCComplex() now tries to convert an
9399 object to complex using its __complex__() method before falling back
9400 to the __float__() method. Therefore, the functions in the cmath
9401 module now can operate on objects that define a __complex__()

Georg Brandl4e933132006-09-06 20:05:58 +00009541- Bug #1542051: Exceptions now correctly call PyObject_GC_UnTrack.

Georg Brandl3ee81df2008-05-17 18:14:43 +000010366- Issue #1339: The smtplib.SMTP class has been refactored a bit such
Gregory P. Smithbde4ae42008-01-17 08:35:49 +000010367 that the SMTP.starttls() caller no longer needs to call ehlo()
10368 beforehand. SMTP.starttls() now raises an exception of the server
Georg Brandl3ee81df2008-05-17 18:14:43 +000010369 does not claim to support starttls. Adds the
10370 SMTP.ehlo_or_helo_if_needed() method. Patch contributed by Bill

Georg Brandl3ee81df2008-05-17 18:14:43 +000010413- Patch #976880: ``mmap`` objects now have an ``rfind`` method that
Andrew M. Kuchling5c60bfc2008-01-19 18:18:41 +000010414 works as expected. ``mmap.find`` also takes an optional ``end``

10451 complex, tuple, list, dict, set, and frozenset. Formerly, it would
10452 silently miscode subclasses of those types. Now, it raises a
10453 ValueError instead.
Raymond Hettinger12e94202007-11-07 01:13:09 +000010454

Gregory P. Smithec10a4a2007-11-05 02:32:26 +000010468- pybsddb.sf.net Bug #477182: Load the database flags at database open
Georg Brandl3ee81df2008-05-17 18:14:43 +000010469 time so that opening a database previously created with the DB_DUP
10470 or DB_DUPSORT flag set will keep the proper behavior on subsequent
10471 opens. Specifically: dictionary assignment to a DB object will
10472 replace all values for a given key when the database allows
10473 duplicate values. DB users should use DB.put(k, v) when they want
10474 to store duplicates; not DB[k] = v.

10481 characters with ASCII value less than 32. Also, it correctly quotes
10482 dots only if they occur on a single line, as opposed to the previous
10483 behavior of quoting dots if they are the second character of any
10484 line.
Georg Brandl4aef7272007-03-13 22:49:43 +000010485

Georg Brandl3ee81df2008-05-17 18:14:43 +000010893- Removed the macfs module. It had been deprecated since Python 2.5.
10894 This lead to the deprecation of macostools.touched() as it relied
10895 solely on macfs and was a no-op under OS X.
