Ned Deily18fae3f2013-01-31 01:24:55 -0800733- Issue #13590: OS X Xcode 4 - improve support for universal extension modules
734 In particular, fix extension module build failures when trying to use
735 32-bit-only installer Pythons on systems with Xcode 4 (currently
736 OS X 10.8, 10.7, and optionally 10.6).
737 * Backport 3.3.0 fixes to 2.7 branch (for release in 2.7.4)
738 * Since Xcode 4 removes ppc support, extension module builds now
739 check for ppc compiler support and by default remove ppc and
740 ppc64 archs when they are not available.
741 * Extension module builds now revert to using system installed
742 headers and libs (/usr and /System/Library) if the SDK used
743 to build the interpreter is not installed or has moved.
744 * Try to avoid building extension modules with deprecated
745 and problematic Apple llvm-gcc compiler. If original compiler
746 is not available, use clang instead by default.

989 in list_repeat (listobject.c) and islice_next (itertoolsmodule.c). These

Ned Deilyc47a4592012-02-11 20:40:24 +01001059 has left two versions of customize_compiler, the original in
1060 distutils.sysconfig and another copy in distutils.ccompiler, with some

Ned Deily0d0ea482012-02-10 12:59:06 +01001065- Issue #13590: On OS X 10.7 and 10.6 with Xcode 4.2, building
1066 Distutils-based packages with C extension modules may fail because
1067 Apple has removed gcc-4.2, the version used to build python.org
1068 64-bit/32-bit Pythons. If the user does not explicitly override
1069 the default C compiler by setting the CC environment variable,
1070 Distutils will now attempt to compile extension modules with clang
1071 if gcc-4.2 is required but not found. Also as a convenience, if
1072 the user does explicitly set CC, substitute its value as the default
1073 compiler in the Distutils LDSHARED configuration variable for OS X.
1074 (Note, the python.org 32-bit-only Pythons use gcc-4.0 and the 10.4u
1075 SDK, neither of which are available in Xcode 4. This change does not
1076 attempt to override settings to support their use with Xcode 4.)

Ned Deily87e82bb2011-06-28 19:52:59 -07001349- Issue #9516: On Mac OS X, change Distutils to no longer globally attempt to
1350 check or set the MACOSX_DEPLOYMENT_TARGET environment variable for the
1351 interpreter process. This could cause failures in non-Distutils subprocesses
1352 and was unreliable since tests or user programs could modify the interpreter
Ezio Melotti302ad8d2013-01-19 19:44:58 +02001353 environment after Distutils set it. Instead, have Distutils set the
Ned Deily87e82bb2011-06-28 19:52:59 -07001354 deployment target only in the environment of each build subprocess. It is
1355 still possible to globally override the default by setting
1356 MACOSX_DEPLOYMENT_TARGET before launching the interpreter; its value must be
1357 greater or equal to the default value, the value with which the interpreter
1358 was built.

1388 the ticker doesn't have to wind down to zero from the old starting point
1389 before the new interval takes effect. And if the user increases the
1390 interval, it makes sure the new limit takes effect right away rather have an
1391 early task switch before recognizing the new interval.

2332 by Andrew Bennetts.

2341
Raymond Hettinger20397532010-09-12 02:11:45 +00002342- Issue #9825: removed __del__ from the definition of collections.OrderedDict.
2343 This prevents user-created self-referencing ordered dictionaries from
2344 becoming permanently uncollectable GC garbage. The downside is that
2345 removing __del__ means that the internal doubly-linked list has to wait for
2346 GC collection rather than freeing memory immediately when the refcnt drops
2347 to zero.
2348

2377
R. David Murray7c4bf552010-08-25 01:45:57 +00002378- Issue #1194222: email.utils.parsedate now returns RFC2822 compliant four
2379 character years even if the message contains RFC822 two character years.
2380
Daniel Stutzbach91287322010-08-24 21:09:30 +00002381- Issue #8750: Fixed MutableSet's methods to correctly handle

2415 when the underlying raw IO channel was e.g. a socket. Report and original
2416 patch by Jason V. Miller.

2601 compared to other unix systems. In particular, os.getgroups() does
2602 not reflect any changes made using os.setgroups() but basicly always
2603 returns the same information as the id command.
2604
2605 os.getgroups() can now return more than 16 groups on MacOSX.

2808 of the number of bytes specified by the start byte.
2809 E.g.: '\xf1\x80AB'.decode('utf-8', 'replace') now returns u'\ufffdAB' and
2810 replaces with U+FFFD only the start byte ('\xf1') and the continuation byte

2822 (2**53+1 == complex(2**53) == 2**53), breaking transivity of equality.

R. David Murray1a14d3d2010-04-12 16:35:19 +00003119- Issue #7585: difflib context and unified diffs now place a tab between
Georg Brandlfee0f442010-05-22 21:26:21 +00003120 filename and date, conforming to the 'standards' they were originally designed
3121 to follow. This improves compatibility with patch tools.

Mark Dickinsond2f3e3f2010-05-05 22:23:58 +00003167 (Optimization was unintentionally turned on in gcc --with-pydebug builds in
3168 2.7 beta1 as a result of the issue #1628484 fix, combined with autoconf's
3169 strange choice of default CFLAGS produced by AC_PROG_CC for gcc.)

3190-----------------
3191
Philip Jenveyaebbaeb2010-04-06 23:24:45 +00003192- Issue #7301: Add environment variable $PYTHONWARNINGS.
3193
Benjamin Peterson3a1dfa22010-04-06 21:50:00 +00003194- Issue #8329: Don't return the same lists from select.select when no fds are
3195 changed.
3196
Georg Brandlfee0f442010-05-22 21:26:21 +00003197- Issue #8259: ``1L << (2**31)`` no longer produces an 'outrageous shift error'
Mark Dickinson82791672010-04-06 16:47:55 +00003198 on 64-bit machines. The shift count for either left or right shift is
3199 permitted to be up to sys.maxsize.
3200
Benjamin Peterson4ceeeb02010-04-03 22:48:51 +00003201- Ensure that tokenization of identifiers is not affected by locale.
3202
Georg Brandlfee0f442010-05-22 21:26:21 +00003203- Issue #1222585: Added LDCXXSHARED for C++ support. Patch by Arfrever.
Tarek Ziadé00002952010-04-03 08:37:59 +00003204
Benjamin Peterson1c7c11e2010-04-03 01:28:57 +00003205- Raise a TypeError when trying to delete a T_STRING_INPLACE struct member.
3206
Georg Brandlfee0f442010-05-22 21:26:21 +00003207- Issue #7994: Issue a PendingDeprecationWarning if object.__format__ is called
3208 with a non-empty format string. This is an effort to future-proof user
3209 code. If a derived class does not currently implement __format__ but later
3210 adds its own __format__, it would most likely break user code that had
Antoine Pitrou01a196a2011-01-02 20:05:11 +00003211 supplied a format string. This will be changed to a DeprecationWarning in
Georg Brandlfee0f442010-05-22 21:26:21 +00003212 Python 3.3 and it will be an error in Python 3.4.
Eric Smithd44b2fc2010-04-02 12:30:56 +00003213
Antoine Pitroua57df2c2010-03-31 21:32:15 +00003214- Issue #8268: Old-style classes (not just instances) now support weak

3226
Victor Stinner66644262010-03-10 22:30:19 +00003227- Issue #3137: Don't ignore errors at startup, especially a keyboard interrupt
Georg Brandlba83f822010-03-14 09:50:54 +00003228 (SIGINT). If an error occurs while importing the site module, the error is
3229 printed and Python exits. Initialize the GIL before importing the site

3244
Georg Brandlfee0f442010-05-22 21:26:21 +00003245- Issue #8257: The Decimal construct now accepts a float instance directly,
3246 converting that float to a Decimal of equal value:
Mark Dickinson8a950712010-04-03 15:47:46 +00003247
3248 >>> Decimal(1.1)
3249 Decimal('1.100000000000000088817841970012523233890533447265625')
3250
Raymond Hettinger34c35b22010-04-03 10:22:00 +00003251- collections.Counter() now supports a subtract() method.
3252
Georg Brandlfee0f442010-05-22 21:26:21 +00003253- The functools module now has a total_ordering() class decorator to simplify
3254 the specification of rich comparisons.
Raymond Hettingera551f312010-04-04 18:34:45 +00003255
Georg Brandlfee0f442010-05-22 21:26:21 +00003256- The functools module also adds cmp_to_key() as a tool to transition old-style
3257 comparison functions to new-style key-functions.
Raymond Hettingera551f312010-04-04 18:34:45 +00003258
Georg Brandlfee0f442010-05-22 21:26:21 +00003259- Issue #8294: The Fraction constructor now accepts Decimal and float instances
3260 directly.
Mark Dickinson7c63eee2010-04-02 22:27:36 +00003261
Georg Brandlfee0f442010-05-22 21:26:21 +00003262- Issue #7279: Comparisons involving a Decimal signaling NaN now signal
3263 InvalidOperation instead of returning False. (Comparisons involving a quiet
3264 NaN are unchanged.) Also, Decimal quiet NaNs are now hashable; Decimal
3265 signaling NaNs remain unhashable.
Mark Dickinsone096e822010-04-02 10:17:07 +00003266
Georg Brandlfee0f442010-05-22 21:26:21 +00003267- Issue #2531: Comparison operations between floats and Decimal instances now
3268 return a result based on the numeric values of the operands; previously they
3269 returned an arbitrary result based on the relative ordering of id(float) and
3270 id(Decimal).
Mark Dickinson99d80962010-04-02 08:53:22 +00003271
Barry Warsawf7f2d6f2010-03-31 21:07:16 +00003272- Issue #8233: When run as a script, py_compile.py optionally takes a single
Georg Brandlfee0f442010-05-22 21:26:21 +00003273 argument `-` which tells it to read files to compile from stdin. Each line is
3274 read on demand and the named file is compiled immediately. (Original patch by
3275 Piotr Ożarowski).
Barry Warsawf7f2d6f2010-03-31 21:07:16 +00003276
Georg Brandlfee0f442010-05-22 21:26:21 +00003277- Issue #3135: Add ``inspect.getcallargs()``, which binds arguments to a

Florent Xicluna58b65662010-03-30 16:29:03 +00003280- Backwards incompatible change: Unicode codepoints line tabulation (0x0B) and
3281 form feed (0x0C) are now considered linebreaks, as specified in Unicode
Georg Brandlfee0f442010-05-22 21:26:21 +00003282 Standard Annex #14. See issue #7643. http://www.unicode.org/reports/tr14/
Florent Xicluna22b24382010-03-30 08:24:06 +00003283
Georg Brandlfee0f442010-05-22 21:26:21 +00003284- Comparisons using one of <, <=, >, >= between a complex instance and a
3285 Fractions instance now raise TypeError instead of returning True/False. This
3286 makes Fraction <=> complex comparisons consistent with int <=> complex, float
3287 <=> complex, and complex <=> complex comparisons.
Mark Dickinson9588d992010-03-27 11:14:37 +00003288

3396 the set of integer codes for which it was used differed between native packing
3397 and standard packing.)

Georg Brandlba83f822010-03-14 09:50:54 +00003705 file position when calling `truncate()`. It would previously change the file
3706 position to the given argument, which goes against the tradition of
Antoine Pitrouf3fa0742010-01-31 22:26:04 +00003707 ftruncate() and other truncation APIs. Patch by Pascal Chambon.
3708

3710 class used to represent files stored inside an archive. The new
3711 implementation is significantly faster and can be wrapped in a
3712 ``io.BufferedReader`` object for more speedups. It also solves an issue
3713 where interleaved calls to ``read()`` and ``readline()`` give wrong results.
3714 Patch by Nir Aides.

Georg Brandlba83f822010-03-14 09:50:54 +00003724- Issue #7748: Since unicode values are supported for some metadata options in
3725 Distutils, the DistributionMetadata get_* methods will now return an utf-8
3726 encoded string for them. This ensures that the upload and register commands
3727 send the correct values to PyPI without any error.

Georg Brandlba83f822010-03-14 09:50:54 +00003998- Issue #7117: ``repr(x)`` for a float x returns a result based on the shortest
3999 decimal string that's guaranteed to round back to x under correct rounding
4000 (with round-half-to-even rounding mode). Previously it gave a string based on
4001 rounding x to 17 decimal digits. repr(x) for a complex number behaves
4002 similarly. On platforms where the correctly-rounded strtod and dtoa code is
4003 not supported (see below), repr is unchanged.
Mark Dickinsonb678de82009-11-19 18:41:49 +00004004
Georg Brandlba83f822010-03-14 09:50:54 +00004005- Issue #7117: On almost all platforms: float-to-string and string-to-float
4006 conversions within Python are now correctly rounded. Places these conversions
4007 occur include: str for floats and complex numbers; the float and complex
4008 constructors; old-style and new-style numeric formatting; serialization and
4009 deserialization of floats and complex numbers using marshal, pickle and json;
4010 parsing of float and imaginary literals in Python code; Decimal-to-float
4011 conversion.
Mark Dickinsonb678de82009-11-19 18:41:49 +00004012
Georg Brandlba83f822010-03-14 09:50:54 +00004013 The conversions use a Python-adapted version of David Gay's well-known dtoa.c,
4014 providing correctly-rounded strtod and dtoa C functions. This code is
4015 supported on Windows, and on Unix-like platforms using gcc, icc or suncc as
4016 the C compiler. There may be a small number of platforms on which correct
4017 operation of this code cannot be guaranteed, so the code is not used: notably,
4018 this applies to platforms where the C double format is not IEEE 754 binary64,
4019 and to platforms on x86 hardware where the x87 FPU is set to 64-bit precision
4020 and Python's configure script is unable to determine how to change the FPU
4021 precision. On these platforms conversions use the platform strtod and dtoa,
4022 as before.

Georg Brandlba83f822010-03-14 09:50:54 +00004024- Issue #7117: Backport round implementation from Python 3.x. ``round()`` now
4025 uses the correctly-rounded string <-> float conversions described above (when
4026 available), and so produces correctly rounded results that will display nicely
4027 under the float repr. There are two related small changes: (1) round now
4028 accepts any class with an ``__index__()`` method for its second argument (but
4029 no longer accepts floats for the second argument), and (2) an excessively
4030 large second integer argument (e.g., ``round(1.234, 10**100)``) no longer
4031 raises an exception.

Georg Brandlba83f822010-03-14 09:50:54 +00004178- Issue #5920: For ``float.__format__()``, change the behavior with the empty
4179 presentation type (that is, not one of 'e', 'f', 'g', or 'n') to be like 'g'
4180 but with at least one decimal point and with a default precision
4181 of 12. Previously, the behavior the same but with a default precision of 6.
4182 This more closely matches ``str()``, and reduces surprises when adding

Georg Brandlba83f822010-03-14 09:50:54 +00004324- Issue #1180193: When importing a module from a .pyc (or .pyo) file with an
4325 existing .py counterpart, override the co_filename attributes of all code
4326 objects if the original filename is obsolete (which can happen if the file has

4381
Georg Brandlba83f822010-03-14 09:50:54 +00004382- Issue #4233: Changed semantic of ``_fileio.FileIO``'s ``close()`` method on
4383 file objects with closefd=False. The file descriptor is still kept open but
4384 the file object behaves like a closed file. The ``FileIO`` object also got a
4385 new readonly attribute ``closefd``.

4404
Benjamin Peterson399b1fe2008-10-25 02:53:28 +00004405- Using ``nonlocal`` as a variable name will now raise a Py3k SyntaxWarning

Georg Brandlba83f822010-03-14 09:50:54 +00004408- On windows, ``os.chdir()`` given unicode was not working if
4409 GetCurrentDirectoryW returned a path longer than MAX_PATH. (But It's doubtful
4410 this code path is really executed because I cannot move to such directory on
4411 win2k)

Georg Brandlba83f822010-03-14 09:50:54 +00004413- Issue #4069: When ``set.remove(element)`` is used with a set element, the
4414 element is temporarily replaced with an equivalent frozenset. But the
4415 eventual KeyError would always report the empty ``frozenset()`` as the missing
4416 key. Now it correctly refers to the initial element.

Walter Dörwalded960ac2009-05-03 22:36:33 +00004436- Issue #5108: Handle %s like %S and %R in PyUnicode_FromFormatV(): Call
4437 PyUnicode_DecodeUTF8() once, remember the result and output it in a second
4438 step. This avoids problems with counting UTF-8 bytes that ignores the effect
4439 of using the replace error handler in PyUnicode_DecodeUTF8().
4440
Walter Dörwald726ba8e2009-05-06 14:32:35 +00004441- Issue #3739: The unicode-internal encoder now reports the number of characters

4443
Georg Brandlba83f822010-03-14 09:50:54 +00004444- Issue #2422: When compiled with the ``--with-valgrind`` option, the pymalloc
4445 allocator will be automatically disabled when running under Valgrind. This
4446 gives improved memory leak detection when running under Valgrind, while taking
4447 advantage of pymalloc at other times.

5655 in the Lib/test directory, which might be read-only for the user running the
5656 tests.

Georg Brandlba83f822010-03-14 09:50:54 +00005670 leak-chasing test runs give sensible results. The previous method of reaping
5671 threads could return successfully while some Thread objects were still
5672 referenced. This also introduces a new private function: ``thread._count()``.
Antoine Pitrou59c44f32009-10-30 17:07:08 +00005673
Georg Brandlba83f822010-03-14 09:50:54 +00005674- Issue #7151: Fixed regrtest -j so that output to stderr from a test no longer

5682 and a new section in the summary report at the end.

Guilherme Polo7f146ab2009-06-21 17:22:50 +00005689- Issue #5450: Moved tests involving loading tk from Lib/test/test_tcl to
5690 Lib/lib-tk/test/test_tkinter/test_loadtk. With this, these tests demonstrate
Georg Brandlba83f822010-03-14 09:50:54 +00005691 the same behaviour as test_ttkguionly (and now also test_tk) which is to skip
5692 the tests if DISPLAY is defined but can't be used.

5698 import both normal and optimised versions of modules. test_heapq and
5699 test_warnings have been adjusted to use it, tests for other modules with both
5700 C and Python implementations in the stdlib can be adjusted to use it over
5701 time.

Georg Brandlba83f822010-03-14 09:50:54 +00005709- regrtest no longer treats ImportError as equivalent to SkipTest. Imports that
5710 should cause a test to be skipped are now done using import_module from test
5711 support, which does the conversion.

5813
Amaury Forgeot d'Arc05e34492008-09-10 22:04:45 +00005814- Issue #3743: In a few places, PY_FORMAT_SIZE_T was incorrectly used with
5815 PyString_FromFormat or PyErr_Format to display size_t values. The macro
5816 PY_FORMAT_SIZE_T is designed to select the correct format for the OS
5817 ``printf`` function, whereas PyString_FromFormat has an independent
5818 implementation and uses "%zd" on all platforms for size_t values.
5819 This makes a difference on win64, where ``printf`` needs "%Id" to display
5820 64bit values.

Benjamin Peterson97179b02008-09-09 20:55:01 +00005822- Issue #3634: _weakref.ref(Exception).__init__() gave invalid return value on

5826 object; previously an int would be returned for small values. the __long__
5827 method is allowed to return either an int or a long, but the behaviour of
5828 float objects should not change to respect backward compatibility.

Antoine Pitroud4ae97b2008-08-29 18:39:48 +00005837 was correctly parsed but parsing of subsequent arguments failed.
5838
Vinay Sajip35e3b032008-09-01 14:33:59 +00005839- Issue #2534: speed up isinstance() and issubclass() by 50-70%, so as to
Antoine Pitrou0668c622008-08-26 22:42:08 +00005840 match Python 2.5 speed despite the __instancecheck__ / __subclasscheck__
5841 mechanism. In the process, fix a bug where isinstance() and issubclass(),
5842 when given a tuple of classes as second argument, were looking up
5843 __instancecheck__ / __subclasscheck__ on the tuple rather than on each
5844 type object.

5938
Jesse Noller438195f2009-01-18 21:04:36 +00005939- Issue #4301: Patch the logging module to add processName support, remove
5940 _check_logger_class from multiprocessing.
5941
Amaury Forgeot d'Arc293924b2008-09-02 23:19:56 +00005942- Issue #2975: When compiling several extension modules with Visual Studio 2008
5943 from the same python interpreter, some environment variables would grow
5944 without limit.
5945
Benjamin Peterson37346b22008-08-23 20:27:43 +00005946- Issue #3643: Added a few more checks to _testcapi to prevent segfaults by
5947 exploitation of poor argument checking.
5948
Gerhard Häringef2276b2008-09-12 13:54:06 +00005949- sqlite3: Changed docstring of iterdump() to mark method as "Non-standard".

Gerhard Häring6e1afcf2008-09-12 18:58:57 +00005951- Issue #3103: Reduced globals symbols used by sqlite3 module and made sure all
5952 remaining ones have "pysqlite_" prefix.
5953
Gerhard Häringe6872eb2008-09-12 22:33:22 +00005954- Issue #3846: Release the GIL during sqlite3_prepare calls. This improves

5962 wrapper for warnings.catch_warnings() that makes it easier to check
5963 that expected warning messages are being reported.
5964
Amaury Forgeot d'Arcfeb8cad2008-09-06 20:53:51 +00005965- Issue #3796: Some tests functions were not enabled in test_float.

Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00005983What's New in Python 2.6 beta 3?
5984================================
5985
Barry Warsaw07a4a382008-08-21 01:15:08 +00005986*Release date: 20-Aug-2008*
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00005987
5988Core and Builtins
5989-----------------
5990
Guido van Rossumf8402962008-08-20 15:01:50 +00005991- Issue #1878: Remove Py_TPFLAGS_HAVE_VERSION_TAG from
5992 Py_TPFLAGS_DEFAULT when not building the core. This means 3rd party
5993 extensions do not automatically benefit from the class attribute
5994 cache; they will have to explicitly add Py_TPFLAGS_HAVE_VERSION_TAG
5995 to their tp_flags field if they care. This is a backwards
5996 compatibility feature; in 3.0, all types will use the cache by
5997 default.
5998
Benjamin Petersonf647dc12008-08-20 01:27:30 +00005999- Keyword arguments can now follow starred arguments. (``f(a, *args,
6000 keyword=23)`` is now valid syntax.)
6001
Thomas Heller0ad5ae02008-08-19 19:25:04 +00006002- ctypes function pointers that are COM methods have a boolean True
6003 value again.
6004
Martin v. Löwisf91d46a2008-08-12 14:49:50 +00006005- Issue #3139: Make buffer-interface thread-safe wrt. PyArg_ParseTuple,
6006 by denying s# to parse objects that have a releasebuffer procedure,
6007 and introducing s*.
6008
Georg Brandl1e13ea92008-08-11 09:07:59 +00006009- Issue #3537: Fix an assertion failure when an empty but presized dict
6010 object was stored in the freelist.
6011
Mark Dickinsonb6467572008-08-04 21:30:09 +00006012- Issue #1481296: Make long(float('nan')) and int(float('nan')) raise
6013 ValueError consistently across platforms.
6014
Amaury Forgeot d'Arc39fd6722008-07-31 21:28:03 +00006015- Issue #3479: On platforms where sizeof(int) is smaller than sizeof(long)
6016 (64bit Unix, for example), unichr() would truncate its argument and return
6017 u'\x00' for unichr(2**32). Now it properly raises an OverflowError.
6018
Neal Norwitze7d8be82008-07-31 17:17:14 +00006019- Apply security patches from Apple.
6020
Amaury Forgeot d'Arc246daed2008-07-31 00:42:16 +00006021- Issue #2542: Now that issubclass() may call arbitrary code, ensure that
6022 PyErr_ExceptionMatches returns 0 when an exception occurs there.
6023
Antoine Pitrou92f82162008-07-25 22:22:08 +00006024- Issue #1819: function calls with several named parameters are now on
6025 average 35% faster (as measured by pybench).
6026
Amaury Forgeot d'Arce4921fe2008-07-21 22:00:38 +00006027- Issue #2378: An unexpected UnboundLocalError or NameError could appear when
6028 the python debugger steps into a class statement: the free variables (local
6029 variables defined in an outer scope) would be deleted from the outer scope.
6030
Gregory P. Smith0470bab2008-07-22 04:46:32 +00006031- Issue #2620: Overflow checking when allocating or reallocating memory
6032 was not always being done properly in some python types and extension
6033 modules. PyMem_MALLOC, PyMem_REALLOC, PyMem_NEW and PyMem_RESIZE have
6034 all been updated to perform better checks and places in the code that
6035 would previously leak memory on the error path when such an allocation
6036 failed have been fixed.
6037
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00006038Library
6039-------
6040
Hirokazu Yamamoto838c79f2008-08-20 13:14:07 +00006041- Issue #3612: Added some missing basic types in ctypes.wintypes.
6042
Benjamin Petersone977ad42008-08-20 01:42:01 +00006043- The methods ``is_in_tuple()``, ``is_vararg()``, and ``is_keywordarg()`` of
6044 symtable.Symbol have been deprecated for removal in 3.0 and the next release.
6045
Amaury Forgeot d'Arc351ffb82008-08-18 19:23:47 +00006046- Issue #2234: distutils failed for some versions of the cygwin compiler. The
6047 version reported by these tools does not necessarily follow the python
6048 version numbering scheme, so the module is less strict when parsing it.
6049
Nick Coghlanf70385a2008-08-18 12:42:46 +00006050- Issue #2235: Added Py3k warnings for types which will become unhashable
6051 under the stricter __hash__ inheritance rules in 3.0. Several types
6052 which did not meet the rules for hash invariants and were already
6053 unhashable in 3.0 have now been explicitly flagged as unhashable in
6054 2.6 as well (collections.Mapping, collections.Set, unittest.TestSuite,
6055 xml.dom.minidom.NamedNodeMap, numbers.Number, UserList.UserList)
6056
Brett Cannon88f801d2008-08-18 00:46:22 +00006057- Update __all__ for cookielib, csv, os, urllib2, and weakref to include things
6058 imported into the module but exposed as part of the module's API.
6059
Brett Cannon7b96f072008-08-18 00:41:11 +00006060- Remove an unneeded import of abc.ABCMeta from 'inspect'.
6061
Brett Cannon46225e72008-08-18 00:36:52 +00006062- Remove unneeded imports of 'sys' and 'warnings' from 'io'.
6063
Brett Cannon25c9d6a2008-08-17 22:10:11 +00006064- Remove unneeded imports of 'warnings' from shelve, filecmp, and dummy_thread.
6065
Hirokazu Yamamoto41a81eb2008-08-17 13:10:46 +00006066- Issue #3575: Incremental decoder's decode function now takes bytearray
6067 by using 's*' instead of 't#'.
6068
Mark Dickinson3e4caeb2009-02-21 20:27:01 +00006069- Issue #2222: Fixed reference leak when occurred os.rename()
Hirokazu Yamamoto7f30a682008-08-17 09:46:56 +00006070 fails unicode conversion on 2nd parameter. (windows only)
6071
Georg Brandl222e2082010-08-01 22:27:39 +00006072- Issue #2464: urllib2 now supports a malformation in the URL received
Facundo Batista94f243a2008-08-17 03:38:39 +00006073 in a redirect.
6074
Brett Cannonabe423e2008-08-16 21:47:07 +00006075- Silence the DeprecationWarning raised when importing mimetools in
Brett Cannon721b1452008-08-16 22:00:27 +00006076 BaseHTTPServer, cgi (and rfc822), httplib.
Brett Cannonabe423e2008-08-16 21:47:07 +00006077
Facundo Batistaeb90b782008-08-16 14:44:07 +00006078- Issue #2776: fixed small issue when handling an URL with double slash
6079 after a 302 response in the case of not going through a proxy.
6080
Antoine Pitroub90a8be2008-08-15 21:03:21 +00006081- Issue #2676: in the email package, content-type parsing was hanging on
6082 pathological input because of quadratic or exponential behaviour of a
6083 regular expression.
6084
Antoine Pitrou11ec65d2008-08-14 21:04:30 +00006085- Issue #3476: binary buffered reading through the new "io" library is now
6086 thread-safe.
6087
Brett Cannonbf3157b2008-08-14 05:00:03 +00006088- Silence the DeprecationWarning of rfc822 when it is imported by mimetools
6089 since mimetools itself is deprecated. Because modules are cached, all
6090 subsequent imports of rfc822 will not raise a visible DeprecationWarning.
6091
Antoine Pitrou9fcd4b32008-08-11 17:21:36 +00006092- Issue #3134: shutil referenced undefined WindowsError symbol.
6093
Robert Schuppenies14646332008-08-10 11:01:53 +00006094- Issue #1342811: Fix leak in Tkinter.Menu.delete. Commands associated to
6095 menu entries were not deleted.
6096
Brett Cannon83e81842008-08-09 23:30:55 +00006097- Copied the implementation of reduce() to _functools.reduce() to have a
6098 version that did not raise a DeprecationWarning under -3.
6099
Antoine Pitrou76b8bee2008-08-09 17:27:23 +00006100- Issue #3205: When iterating over a BZ2File fails allocating memory, raise
6101 a MemoryError rather than silently stop the iteration.
6102
Guido van Rossum59ce9012008-08-09 14:55:34 +00006103- Issue #3487: sre "bytecode" validator. Passing invalid "re-bytecode"
6104 to _sre.compile() will now be rejected. This should not affect anybody
6105 since the re.compile() function never generates invalid re-bytecode.
6106
Skip Montanaroa032bf42008-08-08 22:52:51 +00006107- Issue #3436: Make csv.DictReader's fieldnames attribute a property so that
6108 upon first access it can be automatically initialized from the csv file if
6109 it wasn't initialized during instantiation.
6110
Brett Cannon3aa2a492008-08-06 22:28:09 +00006111- Issue #2338: Create imp.reload() to help with transitioning to Python 3.0 as
6112 the reload() built-in has been removed.
6113
Brett Cannon7e30b672008-08-04 21:52:25 +00006114- Changed code in the following modules/packages to remove warnings raised
Brett Cannonc1b76e42008-08-09 23:06:16 +00006115 while running under the ``-3`` flag: aifc, asynchat, asyncore, bdb, bsddb,
Brett Cannon047e4a92008-08-17 04:16:04 +00006116 ConfigParser, cookielib, csv, difflib, distutils, DocXMLRPCServer, email,
6117 filecmp, fileinput, inspect, logging, modulefinder, pdb, pickle, profile,
6118 pstats, pydoc, re, rlcompleter, SimpleXMLRPCServer, shelve, socket,
6119 subprocess, sqlite3, tarfile, Tkinter, test.test_support, textwrap,
6120 threading, tokenize, traceback, urlparse, wsgiref, xml, xmlrpclib.
Brett Cannon7e30b672008-08-04 21:52:25 +00006121
Lars Gustäbel727bd0b2008-08-02 11:26:39 +00006122- Issue #3039: Fix tarfile.TarFileCompat.writestr() which always
6123 raised an AttributeError.
6124
Benjamin Peterson01a24322008-07-28 23:35:27 +00006125- Issue #2523: Fix quadratic behaviour when read()ing a binary file without
Antoine Pitroude781a42008-08-09 12:43:23 +00006126 asking for a specific length. This problem only affected files opened
6127 using the new "io" module, not the built-in open() function.
Benjamin Peterson01a24322008-07-28 23:35:27 +00006128
Mark Dickinsonfe84cce2008-07-27 06:39:07 +00006129- Issue #3449: Update decimal module to use most recent specification
6130 (v. 1.68) and tests (v. 2.58) from IBM.
6131
Georg Brandl222e2082010-08-01 22:27:39 +00006132- Issue #3437: Bug fix in robotparser parsing of Allow: lines.

6136
Georg Brandlf9efabb2008-07-23 15:16:45 +00006137- Deprecate the "ast" parser function aliases.
6138
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00006139- Issue #3120: On 64-bit Windows the subprocess module was truncating handles.
6140
6141- Issue #3303: Fix a crash in locale.strcoll() when calling it with
6142 invalid arguments.
6143
6144- Issue #3302: Fix several crashes when calling locale's gettext functions
6145 with None arguments.
6146
6147- Issue #3389: Allow resolving dotted names for handlers in logging
6148 configuration files.
6149

6151
Antoine Pitrou5fdfa3e2008-07-25 19:42:26 +00006152- Issue #3394: zipfile.writestr sets external attributes when passed a
6153 file name rather than a ZipInfo instance, so files are extracted with
6154 mode 0600 rather than 000 under Unix.
6155
Gregory P. Smitha36f8fe2008-08-04 00:13:29 +00006156- Issue #1857: subprocess.Popen.poll gained an additional _deadstate keyword
6157 argument in python 2.5, this broke code that subclassed Popen to include its
6158 own poll method. Fixed my moving _deadstate to an _internal_poll method.

6166-------------
6167
Nick Coghlan6e8fef02008-08-18 13:14:22 +00006168- Issue #2235: the C API function PyObject_HashNotImplemented and its
6169 interaction with the tp_hash slot (added in 2.6b2) are now documented
6170
Nick Coghlan2a0c2b12008-08-04 12:47:17 +00006171- Issue #643841: The language reference now provides more detailed
6172 coverage of the lookup process for special methods. The disclaimers
6173 regarding lack of coverage of new-style classes have also been
6174 removed, since the coverage is now fairly reasonable.

Raymond Hettingere3ae6552008-06-20 04:18:15 +00006177What's New in Python 2.6 beta 2?
6178================================
6179
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00006180*Release date: 17-Jul-2008*
6181
Raymond Hettingere3ae6552008-06-20 04:18:15 +00006182Core and Builtins
6183-----------------
6184
Georg Brandl3e483f62008-07-16 22:57:41 +00006185- Issue #3156: Fix inconsistent behavior of the bytearray type: all
6186 its methods now allow for items objects that can be converted to
6187 an integer using operator.index().
6188
Mark Dickinson64b7e502008-07-16 09:40:03 +00006189- Issue #3360: Fix incorrect parsing of '020000000000.0', which
6190 produced a ValueError instead of giving the correct float.
6191
Eric Smitha5fa5a22008-07-16 00:11:49 +00006192- Issue #3083: Add alternate (#) formatting for bin, oct, hex output
6193 for str.format(). This adds the prefix 0b, 0o, or 0x, respectively.
6194
Mark Dickinson7103aa42008-07-15 19:08:33 +00006195- Issue #3008: the float type has a new instance method 'float.hex'
6196 and a new class method 'float.fromhex' to convert floating-point
6197 numbers to and from hexadecimal strings, respectively.
6198
Nick Coghlan6d6bd442008-07-15 15:40:22 +00006199- Issue #2235: __hash__ is once again inherited by default. To allow
6200 collections.Hashable to remain meaningful in the presence of the
6201 default hash implementation (object.__hash__), it is now possible
6202 to explicit block inheritance of hash by setting __hash__=None at
6203 the Python level, or tp_hash=PyObject_HashNotImplemented at the C
6204 level.
6205
Nick Coghlanb028f502008-07-13 14:52:36 +00006206- Issue #3221: Issue a RuntimeWarning instead of raising SystemError if
6207 the parent module cannot be found while performing an absolute import.
6208 This means that an incorrectly defined __package__ attribute will
6209 now only prevent relative imports in that module rather than causing
6210 all imports from that module to fail.
6211
Nick Coghlan14ff9942008-07-08 14:21:42 +00006212- Issue #2517: Allow unicode messages in Exceptions again by correctly
6213 bypassing the instance dictionary when looking up __unicode__ on
6214 new-style classes.
6215
Amaury Forgeot d'Arcbdd941f2008-07-01 20:38:04 +00006216- Issue #3242: Fix a crash inside the print statement, if sys.stdout is
6217 set to a custom object whose write() method happens to install
6218 another file in sys.stdout.
6219
Amaury Forgeot d'Arc1f40c8a2008-06-30 22:42:40 +00006220- Issue #3088: Corrected a race condition in classes derived from
6221 threading.local: the first member set by a thread could be saved in
6222 another thread's dictionary.
6223
Mark Dickinson1ec2fcd2008-06-20 14:53:43 +00006224- Issue #3004: Minor change to slice.indices(): the start and stop
6225 arguments are now treated identically, making the behaviour easier
6226 to describe and understand. For example, slice(None, -10,
6227 1).indices(9) now returns (0, 0, 1) instead of (0, -1, 1), and
6228 slice(None, 10, -1).indices(10) returns (9, 9, -1) instead of (9,

6682 mode or even as a 4-way universal binary (that is, PPC, i386,
Georg Brandl5cc774e2008-06-11 20:28:06 +00006683 PPC64 and x86_64 support in one binary).
Ronald Oussoren5640ce22008-06-05 12:58:24 +00006684
6685 This is controlled by the configure argument ``--with-universal-archs``:
6686
6687 - ``--with-universal-archs=all``: install 4-way universal
6688
6689 - ``--with-universal-archs=32-bit``: install 2-way universal, 32-bit (the default)
6690
6691 - ``--with-universal-archs=64-bit``: install 2-way universal, 64-bit
6692
6693 This option should be used in combination with ``--enable-universalsdk=``.

6732 two handlers that derive the same default base class.

Georg Brandl3ee81df2008-05-17 18:14:43 +00006745- Issue #1631171: Re-implement the 'warnings' module in C (the
6746 original Python code has been kept as backup). This will allow for
6747 using the 'warning's machinery in such places as the parser where
6748 use of pure Python code is not possible. Both the ``showarning()``
6749 and ``formatwarning()`` gain an optional 'line' argument which is
6750 not called by default for backwards-compatibility reasons. Setting
6751 ``warnings.showwarning()`` to an implementation that lacks support
6752 for the ``line`` argument will raise a DeprecationWarning.

6776
Gregory P. Smithd59fefb2008-04-22 08:11:33 +00006777- The getpass module has been improved on Unix. It now uses /dev/tty

Georg Brandl3ee81df2008-05-17 18:14:43 +00006815- Issue #2550: The approach used by client/server code for obtaining
6816 ports to listen on in network-oriented tests has been refined in an
6817 effort to facilitate running multiple instances of the entire
6818 regression test suite in parallel without issue.
6819 test_support.bind_port() has been fixed such that it will always
6820 return a unique port -- which wasn't always the case with the
6821 previous implementation, especially if socket options had been set
6822 that affected address reuse (i.e. SO_REUSEADDR, SO_REUSEPORT). The
6823 new implementation of bind_port() will actually raise an exception
6824 if it is passed an AF_INET/SOCK_STREAM socket with either the
6825 SO_REUSEADDR or SO_REUSEPORT socket option set. Furthermore, if
6826 available, bind_port() will set the SO_EXCLUSIVEADDRUSE option on
6827 the socket it's been passed. This currently only applies to
6828 Windows. This option prevents any other sockets from binding to the
6829 host/port we've bound to, thus removing the possibility of the
6830 'non-deterministic' behaviour, as Microsoft puts it, that occurs
6831 when a second SOCK_STREAM socket binds and accepts to a host/port
6832 that's already been bound by another socket. The optional preferred
6833 port parameter to bind_port() has been removed. Under no
6834 circumstances should tests be hard coding ports!
6835
6836 test_support.find_unused_port() has also been introduced, which will
6837 pass a temporary socket object to bind_port() in order to obtain an
6838 unused port. The temporary socket object is then closed and
6839 deleted, and the port is returned. This method should only be used
6840 for obtaining an unused port in order to pass to an external program
6841 (i.e. the -accept [port] argument to openssl's s_server mode) or as
6842 a parameter to a server-oriented class that doesn't give you direct
6843 access to the underlying socket used.
6844
6845 Finally, test_support.HOST has been introduced, which should be used
6846 for the host argument of any relevant socket calls (i.e. bind and
6847 connect).
Trent Nelsone41b0062008-04-08 23:47:30 +00006848
6849 The following tests were updated to following the new conventions:
Georg Brandl3ee81df2008-05-17 18:14:43 +00006850 test_socket, test_smtplib, test_asyncore, test_ssl, test_httplib,
Trent Nelsone41b0062008-04-08 23:47:30 +00006851 test_poplib, test_ftplib, test_telnetlib, test_socketserver,
6852 test_asynchat and test_socket_ssl.
6853
Georg Brandl3ee81df2008-05-17 18:14:43 +00006854 It is now possible for multiple instances of the regression test
6855 suite to run in parallel without issue.

Eric Smitha73fbe72008-02-23 03:09:44 +00007134- Added the future_builtins module, which contains hex() and oct().
7135 These are the PEP 3127 version of these functions, designed to be
7136 compatible with the hex() and oct() builtins from Python 3.0. They
7137 differ slightly in their output formats from the existing, unchanged
7138 Python 2.6 builtins. The expected usage of the future_builtins
7139 module is:
7140 from future_builtins import hex, oct
7141
Eric Smith7ef40bf2008-02-20 23:34:22 +00007142- Issue #1600: Modifed PyOS_ascii_formatd to use at most 2 digit
7143 exponents for exponents with absolute value < 100. Follows C99
7144 standard. This is a change on Windows, which would use 3 digits.
7145 Also, added 'n' to the formats that PyOS_ascii_formatd understands,
7146 so that any alterations it does to the resulting string will be
7147 available in stringlib/formatter.h (for float.__format__).
7148
Eric Smith5a3c1352008-02-19 13:21:56 +00007149- Implemented PEP 3101, Advanced String Formatting. This adds a new
7150 builtin format(); a format() method for str and unicode; a
7151 __format__() method to object, str, unicode, int, long, float, and
7152 datetime; the class string.Formatter; and the C API
7153 PyObject_Format().
7154
Georg Brandl3ee81df2008-05-17 18:14:43 +00007155- Fixed several potential crashes, all caused by specially crafted
7156 __del__ methods exploiting objects in temporarily inconsistent
7157 state.
Amaury Forgeot d'Arc632fad32008-02-16 20:55:24 +00007158
Vinay Sajipb7edfc42008-04-02 21:10:23 +00007159- Issue #2115: Important speedup in setting __slot__ attributes. Also
Georg Brandl3ee81df2008-05-17 18:14:43 +00007160 prevent a possible crash: an Abstract Base Class would try to access
7161 a slot on a registered virtual subclass.
Amaury Forgeot d'Arc60d6c7f2008-02-15 21:22:45 +00007162

Georg Brandl3ee81df2008-05-17 18:14:43 +00007166- Clear all free lists during a gc.collect() of the highest generation
7167 in order to allow pymalloc to free more arenas. Python may give back
7168 memory to the OS earlier.
Christian Heimes3b718a72008-02-14 12:47:33 +00007169
Georg Brandl3ee81df2008-05-17 18:14:43 +00007170- Issue #2045: Fix an infinite recursion triggered when printing a
7171 subclass of collections.defaultdict, if its default_factory is set
7172 to a bound method.
Amaury Forgeot d'Arcb01aa432008-02-08 00:56:02 +00007173
Christian Heimesf75dbef2008-02-08 00:11:31 +00007174- Fixed a minor memory leak in dictobject.c. The content of the free
7175 list was not freed on interpreter shutdown.
7176
Georg Brandl21e99f42010-03-07 15:23:59 +00007177- Limit free list of method and built-in function objects to 256
Georg Brandl3ee81df2008-05-17 18:14:43 +00007178 entries each.
Christian Heimes6075a822008-02-06 12:44:34 +00007179
Georg Brandl3ee81df2008-05-17 18:14:43 +00007180- Patch #1953: Added ``sys._compact_freelists()`` and the C API
7181 functions ``PyInt_CompactFreeList`` and ``PyFloat_CompactFreeList``
Christian Heimes422051a2008-02-04 18:00:12 +00007182 to compact the internal free lists of pre-allocted ints and floats.
7183
Georg Brandl3ee81df2008-05-17 18:14:43 +00007184- Issue #1983: Fixed return type of fork(), fork1() and forkpty()
7185 calls. Python expected the return type int but the fork familie
7186 returns pi_t.
Christian Heimes951cc0f2008-01-31 23:08:23 +00007187
Georg Brandl3ee81df2008-05-17 18:14:43 +00007188- Issue #1678380: Fix a bug that identifies 0j and -0j when they
7189 appear in the same code unit.
Mark Dickinson105be772008-01-31 22:17:37 +00007190
Georg Brandl3ee81df2008-05-17 18:14:43 +00007191- Issue #2025: Add tuple.count() and tuple.index() methods to comply
7192 with the collections.Sequence API.

7198 the internal lookup cache for ref leak tests.
Christian Heimes908caac2008-01-27 23:34:59 +00007199
Georg Brandl3ee81df2008-05-17 18:14:43 +00007200- Patch #1473257: generator objects gain a gi_code attribute. This is
7201 the same object as the func_code attribute of the function that
7202 produced the generator.
Georg Brandl0cdf9a32008-01-26 14:14:20 +00007203
Georg Brandl3ee81df2008-05-17 18:14:43 +00007204- Issue #1920: "while 0" statements were completely removed by the
7205 compiler, even in the presence of an "else" clause, which is
7206 supposed to be run when the condition is false. Now the compiler
7207 correctly emits bytecode for the "else" suite.
Amaury Forgeot d'Arc31eaafe2008-01-24 22:59:25 +00007208
Guido van Rossumeead05f2008-01-24 18:21:02 +00007209- A few crashers fixed: weakref_in_del.py (issue #1377858);
7210 loosing_dict_ref.py (issue #1303614, test67.py);
7211 borrowed_ref_[34].py (not in tracker).
7212
Vinay Sajipd7cf32e2008-01-24 12:43:33 +00007213- Issue #1069410: The "can't load dll" message box on Windows is
Christian Heimesb2302ba2008-01-23 17:15:06 +00007214 suppressed while an extension is loaded by calling SetErrorMode in
7215 dynload_win.c. The error is still reported properly.
7216
Georg Brandl3ee81df2008-05-17 18:14:43 +00007217- Issue #1915: Python compiles with --enable-unicode=no again. However
Christian Heimes082c9b02008-01-23 14:20:50 +00007218 several extension methods and modules do not work without unicode
7219 support.
7220
Georg Brandl26543b12008-01-21 18:36:51 +00007221- Issue #1882: when compiling code from a string, encoding cookies in the
7222 second line of code were not always recognized correctly.
7223
Georg Brandl14404b62008-01-19 19:27:05 +00007224- Issue #1679: "0x" was taken as a valid integer literal.
7225
Georg Brandl6caad7d2008-01-26 14:19:22 +00007226- Issue #1865: ``bytes`` as an alias for ``str`` and b"" as an alias "" were
Christian Heimes288e89a2008-01-18 18:24:07 +00007227 added.
7228
Christian Heimesc94e2b52008-01-14 04:13:37 +00007229- sys.float_info / PyFloat_GetInfo: The floating point information
7230 object was converted from a dict to a specialized structseq object.
7231
Georg Brandl3ee81df2008-05-17 18:14:43 +00007232- Patch #1816: Added sys.flags structseq. It exposes the status of
7233 most command line arguments and PYTHON* environment variables.
Christian Heimesf31b69f2008-01-14 03:42:48 +00007234
Georg Brandl3ee81df2008-05-17 18:14:43 +00007235- Objects/structseq.c: Implemented new structseq representation. The
7236 patch makes structseqs (e.g. the return value of os.stat) more
7237 readable.
Christian Heimes9c201962008-01-14 03:33:52 +00007238
Georg Brandl3ee81df2008-05-17 18:14:43 +00007239- Patch #1700288: added a type attribute cache that caches method

Georg Brandl3ee81df2008-05-17 18:14:43 +00007296- Patch #1739468: Directories and zipfiles containing a __main__.py
7297 file can now be directly executed by passing their name to the
7298 interpreter. The directory/zipfile is automatically inserted as the
7299 first entry in sys.path.

Georg Brandl3ee81df2008-05-17 18:14:43 +00007301- Issue #1265: Fix a problem with sys.settrace, if the tracing
7302 function uses a generator expression when at the same time the
7303 executed code is closing a paused generator.
Amaury Forgeot d'Arc0d75f092007-11-13 21:54:28 +00007304
Raymond Hettinger1760c8a2007-11-08 02:52:43 +00007305- sets and frozensets now have an isdisjoint() method.

7310
Georg Brandl21e99f42010-03-07 15:23:59 +00007311- The enumerate() built-in function is no longer bounded to sequences
Georg Brandl3ee81df2008-05-17 18:14:43 +00007312 smaller than LONG_MAX. Formerly, it raised an OverflowError. Now,
7313 automatically shifts from ints to longs.
Raymond Hettinger8f669372007-10-03 21:18:11 +00007314
Georg Brandl3ee81df2008-05-17 18:14:43 +00007315- Issue #1686386: Tuple's tp_repr did not take into account the
7316 possibility of having a self-referential tuple, which is possible
7317 from C code. Nor did object's tp_str consider that a type's tp_str
7318 could do something that could lead to an inifinite recursion.
7319 Py_ReprEnter() and Py_EnterRecursiveCall(), respectively, fixed the
7320 issues.
Brett Cannon0b14f242007-09-30 19:45:10 +00007321
Georg Brandl3ee81df2008-05-17 18:14:43 +00007322- Issue #1164: It was possible to trigger deadlock when using the
7323 'print' statement to write to a file since the GIL was not released
7324 as needed. Now PyObject_Print() does the right thing along with
7325 various tp_print implementations of the built-in types and those in
7326 the collections module.
Brett Cannon01531592007-09-17 03:28:34 +00007327
Georg Brandl3ee81df2008-05-17 18:14:43 +00007328- Issue #1147: Exceptions were directly allowing string exceptions in

7330 allowed.

Brett Cannona0c05512007-09-10 21:38:27 +00007334
Brett Cannon1e534b52007-09-07 04:18:30 +00007335- Issue #1202533: Fix infinite recursion calls triggered by calls to
Georg Brandl3ee81df2008-05-17 18:14:43 +00007336 PyObject_Call() never calling back out to Python code to trigger
7337 recursion depth updates/checks. Required the creation of a static
7338 RuntimeError instance in case normalizing an exception put the
7339 recursion check value past its limit. Fixes crashers
7340 infinite_rec_(1|2|4|5).py.
Brett Cannon1e534b52007-09-07 04:18:30 +00007341

Neal Norwitz0ac60192007-05-27 04:08:54 +00007355- Add new attribute names for function objects. All the func_* become
Georg Brandl3ee81df2008-05-17 18:14:43 +00007356 __*__ attributes. (Some already existed, e.g., __doc__ and
7357 __name__.)
Neal Norwitz0ac60192007-05-27 04:08:54 +00007358
Neal Norwitz8b2bfbc2007-05-23 06:35:32 +00007359- Add -3 option to the interpreter to warn about features that are
7360 deprecated and will be changed/removed in Python 3.0.
7361
Georg Brandl2134e752007-05-21 20:34:16 +00007362- Patch #1686487: you can now pass any mapping after '**' in function
7363 calls.
7364
Collin Winter62903052007-05-18 23:11:24 +00007365- except clauses may now be spelled either "except E, target:" or
Georg Brandl3ee81df2008-05-17 18:14:43 +00007366 "except E as target:". This is to provide forwards compatibility
7367 with Python 3.0.

Vinay Sajip8549ce32007-05-06 17:53:37 +00007374- When __slots__ are set to a unicode string, make it work the same as
Neal Norwitzcbd9ee62007-04-14 05:25:50 +00007375 setting a plain string, ie don't expand to single letter identifiers.
7376
Raymond Hettinger13936692007-04-11 18:40:58 +00007377- Request #1191699: Slices can now be pickled.
7378
Raymond Hettinger4db5fe92007-04-12 04:10:00 +00007379- Request #1193128: str.translate() now allows a None argument for
7380 translations that only remove characters without re-mapping the
7381 remaining characters.
7382
Georg Brandl5cb76c12007-03-21 09:00:39 +00007383- Patch #1682205: a TypeError while unpacking an iterable is no longer

7385
Neal Norwitzaa754b72007-03-21 06:39:48 +00007386- Remove unused file Python/fmod.c.
7387
Guido van Rossum143b5642007-03-23 04:58:42 +00007388- Bug #1683368: The object.__init__() and object.__new__() methods are
7389 now stricter in rejecting excess arguments. The only time when
7390 either allows excess arguments is when it is not overridden and the
7391 other one is. For backwards compatibility, when both are
7392 overridden, it is a deprecation warning (for now; maybe a Py3k
Guido van Rossum234b1ff2007-03-23 19:39:01 +00007393 warning later). Also, type.__init__() insists on the same signature
7394 as supported by type.__new__().
Guido van Rossum143b5642007-03-23 04:58:42 +00007395
Georg Brandl3ee81df2008-05-17 18:14:43 +00007396- Patch #1675423: PyComplex_AsCComplex() now tries to convert an
7397 object to complex using its __complex__() method before falling back
7398 to the __float__() method. Therefore, the functions in the cmath
7399 module now can operate on objects that define a __complex__()
7400 method.
Georg Brandl2b869942007-03-17 16:08:45 +00007401
Georg Brandl3ee81df2008-05-17 18:14:43 +00007402- Patch #1623563: allow __class__ assignment for classes with

7404 same slot names.
Žiga Seilnacht6f2d09c2007-03-16 11:59:38 +00007405

7411 its type.

7417
Georg Brandl7b9c5552007-03-12 14:30:05 +00007418- Bug #1678647: write a newline after printing an exception in any
7419 case, even when converting the value to a string failed.
7420
Georg Brandl871f1bc2007-03-12 13:17:36 +00007421- The dir() function has been extended to call the __dir__() method on
Georg Brandl3ee81df2008-05-17 18:14:43 +00007422 its argument, if it exists. If not, it will work like before. This
7423 allows customizing the output of dir() in the presence of a
7424 __getattr__().

Georg Brandl3ee81df2008-05-17 18:14:43 +00007432- Patch #1491866: change the complex() constructor to allow
7433 parthensized forms. This means complex(repr(x)) now works instead of
7434 raising a ValueError.
Collin Wintere38051d2007-03-09 20:33:07 +00007435
Georg Brandlaa2321b2007-03-07 00:40:28 +00007436- Patch #703779: unset __file__ in __main__ after running a file. This
Georg Brandl3ee81df2008-05-17 18:14:43 +00007437 makes the filenames the warning module prints much more sensible
7438 when a PYTHONSTARTUP file is used.
Georg Brandlaa2321b2007-03-07 00:40:28 +00007439
Georg Brandl49aafc92007-03-07 00:34:46 +00007440- Variant of patch #697613: don't exit the interpreter on a SystemExit
7441 exception if the -i command line option or PYTHONINSPECT environment
Georg Brandl3ee81df2008-05-17 18:14:43 +00007442 variable is given, but break into the interactive interpreter just
7443 like on other exceptions or normal program exit.

Georg Brandl098cd692007-03-06 12:17:50 +00007450
Georg Brandl0fca97a2007-03-05 22:28:08 +00007451- Patch #1674228: when assigning a slice (old-style), check for the
7452 sq_ass_slice instead of the sq_slice slot.
7453
Georg Brandl3ee81df2008-05-17 18:14:43 +00007454- When printing an unraisable error, don't print exceptions. before
7455 the name. This duplicates the behavior whening normally printing
7456 exceptions.

8084 -- the failure just occurred later, with a more cumbersome
8085 exception.

Georg Brandl3ee81df2008-05-17 18:14:43 +00008366- Issue #829951: In the smtplib module, SMTP.starttls() now complies
8367 with RFC 3207 and forgets any knowledge obtained from the server not
8368 obtained from the TLS negotiation itself. Patch contributed by Bill
8369 Fenner.
Gregory P. Smith2b3ba582008-01-17 08:03:17 +00008370
Georg Brandl3ee81df2008-05-17 18:14:43 +00008371- Issue #1339: The smtplib.SMTP class has been refactored a bit such
Gregory P. Smithbde4ae42008-01-17 08:35:49 +00008372 that the SMTP.starttls() caller no longer needs to call ehlo()
8373 beforehand. SMTP.starttls() now raises an exception of the server
Georg Brandl3ee81df2008-05-17 18:14:43 +00008374 does not claim to support starttls. Adds the
8375 SMTP.ehlo_or_helo_if_needed() method. Patch contributed by Bill
8376 Fenner.

Georg Brandl3ee81df2008-05-17 18:14:43 +00008430- itertools.chain() now has an alternate constructor,

8456 complex, tuple, list, dict, set, and frozenset. Formerly, it would
8457 silently miscode subclasses of those types. Now, it raises a
8458 ValueError instead.
Raymond Hettinger12e94202007-11-07 01:13:09 +00008459

Georg Brandl3ee81df2008-05-17 18:14:43 +00008474 time so that opening a database previously created with the DB_DUP
8475 or DB_DUPSORT flag set will keep the proper behavior on subsequent
8476 opens. Specifically: dictionary assignment to a DB object will
8477 replace all values for a given key when the database allows
8478 duplicate values. DB users should use DB.put(k, v) when they want
8479 to store duplicates; not DB[k] = v.
Gregory P. Smithec10a4a2007-11-05 02:32:26 +00008480

8486 characters with ASCII value less than 32. Also, it correctly quotes
8487 dots only if they occur on a single line, as opposed to the previous
8488 behavior of quoting dots if they are the second character of any
8489 line.
Georg Brandl4aef7272007-03-13 22:49:43 +00008490

Guido van Rossum7c862f82007-12-13 20:50:10 +00008752- Bug #1608: use -fwrapv when GCC supports it. This is important,
8753 newer GCC versions may optimize away overflow buffer overflow checks
8754 without this option!
8755
Martin v. Löwis63bf1492007-11-12 05:14:05 +00008756- Patch #1418: Make the AC_REPLACE_FUNCS object files actually work.

Raymond Hettingerdc1d1ba2007-11-07 02:45:46 +00008758- Add a FAST_LOOPS build option that speeds-up looping by trading away
Georg Brandl3ee81df2008-05-17 18:14:43 +00008759 periodic threadstate and signal checking in tight loops. By
8760 default, this option is turned-off. It should only be enabled in
8761 debugged, performance critical applications.

8777 returned by python-config if Python was built with --enable-shared
8778 because that prevented the shared library from being used.

8812-----
8813
Georg Brandl3ee81df2008-05-17 18:14:43 +00008814- Unified naming convention for free lists and their limits. All free
8815 lists in Object/ are named ``free_list``, the counter ``numfree``
8816 and the upper limit is a macro ``PyName_MAXFREELIST`` inside an
8817 #ifndef block.
Christian Heimes5b970ad2008-02-06 13:33:44 +00008818
Georg Brandl3ee81df2008-05-17 18:14:43 +00008819- ``PySet_Add()`` can now modify a newly created frozenset. Similarly
8820 to ``PyTuple_SetItem``, it can be used to populate a brand new
8821 frozenset; but it does not steal a reference to the added item.
Amaury Forgeot d'Arccab3d982008-02-03 22:51:43 +00008822
Vinay Sajipb7edfc42008-04-02 21:10:23 +00008823- Added ``PySet_Check()`` and ``PyFrozenSet_Check()`` to the set API.

8829- Patch #1720595: add T_BOOL to the range of structmember types.
8830
8831- Issue #1534: Added ``PyFloat_GetMax()``, ``PyFloat_GetMin()`` and
8832 ``PyFloat_GetInfo()`` to the float API.
8833
Georg Brandl3ee81df2008-05-17 18:14:43 +00008834- Issue #1521: On 64bit platforms, using PyArgs_ParseTuple with the t#
8835 of w# format code incorrectly truncated the length to an int, even
8836 when PY_SSIZE_T_CLEAN is set. The str.decode method used to return
8837 incorrect results with huge strings.
Georg Brandl6caad7d2008-01-26 14:19:22 +00008838
Georg Brandl3ee81df2008-05-17 18:14:43 +00008839- Issue #1629: Renamed Py_Size, Py_Type and Py_Refcnt to Py_SIZE,

8857- Fix some leftovers from the conversion from int to Py_ssize_t
8858 (relevant to strings and sequences of more than 2**31 items).
8859
8860- Make _PyGILState_NoteThreadState() static, it was not used anywhere
8861 outside of pystate.c and should not be necessary.
8862
Georg Brandl3ee81df2008-05-17 18:14:43 +00008863- ``PyImport_Import`` and ``PyImport_ImportModule`` now always do
8864 absolute imports. In earlier versions they might have used relative
8865 imports under some conditions.
Christian Heimes000a0742008-01-03 22:16:32 +00008866
Georg Brandl3ee81df2008-05-17 18:14:43 +00008867- Added case insensitive comparison methods ``PyOS_stricmp(char*,
8868 char*)`` and ``PyOS_strnicmp(char*, char*, Py_ssize_t)``.
Christian Heimes000a0742008-01-03 22:16:32 +00008869
Georg Brandl3ee81df2008-05-17 18:14:43 +00008870- Bug #1542693: remove semi-colon at end of PyImport_ImportModuleEx

8878 requires Windows 2000 or greater. The _WINVER and NTDDI_VERSION
8879 macros are set to Win2k for x86/32bit builds and WinXP for AMD64
8880 builds.
Christian Heimes95d64472008-02-09 19:55:22 +00008881

Georg Brandl3ee81df2008-05-17 18:14:43 +00008895- Removed the macfs module. It had been deprecated since Python 2.5.
8896 This lead to the deprecation of macostools.touched() as it relied
8897 solely on macfs and was a no-op under OS X.
