Ned Deily18fae3f2013-01-31 01:24:55 -0800991- Issue #13590: OS X Xcode 4 - improve support for universal extension modules
992 In particular, fix extension module build failures when trying to use
993 32-bit-only installer Pythons on systems with Xcode 4 (currently
994 OS X 10.8, 10.7, and optionally 10.6).
995 * Backport 3.3.0 fixes to 2.7 branch (for release in 2.7.4)
996 * Since Xcode 4 removes ppc support, extension module builds now
997 check for ppc compiler support and by default remove ppc and
998 ppc64 archs when they are not available.
999 * Extension module builds now revert to using system installed
1000 headers and libs (/usr and /System/Library) if the SDK used
1001 to build the interpreter is not installed or has moved.
1002 * Try to avoid building extension modules with deprecated
1003 and problematic Apple llvm-gcc compiler. If original compiler
1004 is not available, use clang instead by default.

1359 in list_repeat (listobject.c) and islice_next (itertoolsmodule.c). These

Ned Deily0d0ea482012-02-10 12:59:06 +01001435- Issue #13590: On OS X 10.7 and 10.6 with Xcode 4.2, building
1436 Distutils-based packages with C extension modules may fail because
1437 Apple has removed gcc-4.2, the version used to build python.org
1438 64-bit/32-bit Pythons. If the user does not explicitly override
1439 the default C compiler by setting the CC environment variable,
1440 Distutils will now attempt to compile extension modules with clang
1441 if gcc-4.2 is required but not found. Also as a convenience, if
1442 the user does explicitly set CC, substitute its value as the default
1443 compiler in the Distutils LDSHARED configuration variable for OS X.
1444 (Note, the python.org 32-bit-only Pythons use gcc-4.0 and the 10.4u
1445 SDK, neither of which are available in Xcode 4. This change does not
1446 attempt to override settings to support their use with Xcode 4.)

Ned Deily87e82bb2011-06-28 19:52:59 -07001696- Issue #9516: On Mac OS X, change Distutils to no longer globally attempt to
1697 check or set the MACOSX_DEPLOYMENT_TARGET environment variable for the
1698 interpreter process. This could cause failures in non-Distutils subprocesses
1699 and was unreliable since tests or user programs could modify the interpreter
Ezio Melotti302ad8d2013-01-19 19:44:58 +02001700 environment after Distutils set it. Instead, have Distutils set the
Ned Deily87e82bb2011-06-28 19:52:59 -07001701 deployment target only in the environment of each build subprocess. It is
1702 still possible to globally override the default by setting
1703 MACOSX_DEPLOYMENT_TARGET before launching the interpreter; its value must be
1704 greater or equal to the default value, the value with which the interpreter
1705 was built.

1735 the ticker doesn't have to wind down to zero from the old starting point
1736 before the new interval takes effect. And if the user increases the
1737 interval, it makes sure the new limit takes effect right away rather have an
1738 early task switch before recognizing the new interval.

Raymond Hettinger20397532010-09-12 02:11:45 +00002718- Issue #9825: removed __del__ from the definition of collections.OrderedDict.
2719 This prevents user-created self-referencing ordered dictionaries from
2720 becoming permanently uncollectable GC garbage. The downside is that
2721 removing __del__ means that the internal doubly-linked list has to wait for
2722 GC collection rather than freeing memory immediately when the refcnt drops
2723 to zero.

2732 original error is re-raised.

Georg Brandlfee0f442010-05-22 21:26:21 +00003461- Issue #8451: Syslog module now uses basename(sys.argv[0]) instead of the
3462 string "python" as the *ident*. openlog() arguments are all optional and
3463 keywords.

R. David Murray1a14d3d2010-04-12 16:35:19 +00003495- Issue #7585: difflib context and unified diffs now place a tab between
Georg Brandlfee0f442010-05-22 21:26:21 +00003496 filename and date, conforming to the 'standards' they were originally designed
3497 to follow. This improves compatibility with patch tools.

Georg Brandlfee0f442010-05-22 21:26:21 +00003542- Issue #8625: Turn off optimization in ``--with-pydebug`` builds with gcc.
Mark Dickinsond2f3e3f2010-05-05 22:23:58 +00003543 (Optimization was unintentionally turned on in gcc --with-pydebug builds in
3544 2.7 beta1 as a result of the issue #1628484 fix, combined with autoconf's
3545 strange choice of default CFLAGS produced by AC_PROG_CC for gcc.)

3566-----------------
3567
Philip Jenveyaebbaeb2010-04-06 23:24:45 +00003568- Issue #7301: Add environment variable $PYTHONWARNINGS.
3569
Benjamin Peterson3a1dfa22010-04-06 21:50:00 +00003570- Issue #8329: Don't return the same lists from select.select when no fds are
3571 changed.
3572
Georg Brandlfee0f442010-05-22 21:26:21 +00003573- Issue #8259: ``1L << (2**31)`` no longer produces an 'outrageous shift error'
Mark Dickinson82791672010-04-06 16:47:55 +00003574 on 64-bit machines. The shift count for either left or right shift is
3575 permitted to be up to sys.maxsize.
3576
Benjamin Peterson4ceeeb02010-04-03 22:48:51 +00003577- Ensure that tokenization of identifiers is not affected by locale.
3578
Georg Brandlfee0f442010-05-22 21:26:21 +00003579- Issue #1222585: Added LDCXXSHARED for C++ support. Patch by Arfrever.
Tarek Ziadé00002952010-04-03 08:37:59 +00003580
Benjamin Peterson1c7c11e2010-04-03 01:28:57 +00003581- Raise a TypeError when trying to delete a T_STRING_INPLACE struct member.
3582
Georg Brandlfee0f442010-05-22 21:26:21 +00003583- Issue #7994: Issue a PendingDeprecationWarning if object.__format__ is called
3584 with a non-empty format string. This is an effort to future-proof user
3585 code. If a derived class does not currently implement __format__ but later
3586 adds its own __format__, it would most likely break user code that had
Antoine Pitrou01a196a2011-01-02 20:05:11 +00003587 supplied a format string. This will be changed to a DeprecationWarning in
Georg Brandlfee0f442010-05-22 21:26:21 +00003588 Python 3.3 and it will be an error in Python 3.4.
Eric Smithd44b2fc2010-04-02 12:30:56 +00003589
Antoine Pitroua57df2c2010-03-31 21:32:15 +00003590- Issue #8268: Old-style classes (not just instances) now support weak

Victor Stinner66644262010-03-10 22:30:19 +00003603- Issue #3137: Don't ignore errors at startup, especially a keyboard interrupt
Georg Brandlba83f822010-03-14 09:50:54 +00003604 (SIGINT). If an error occurs while importing the site module, the error is
3605 printed and Python exits. Initialize the GIL before importing the site
Victor Stinner66644262010-03-10 22:30:19 +00003606 module.

3620
Georg Brandlfee0f442010-05-22 21:26:21 +00003621- Issue #8257: The Decimal construct now accepts a float instance directly,
3622 converting that float to a Decimal of equal value:
Mark Dickinson8a950712010-04-03 15:47:46 +00003623
3624 >>> Decimal(1.1)
3625 Decimal('1.100000000000000088817841970012523233890533447265625')
3626
Raymond Hettinger34c35b22010-04-03 10:22:00 +00003627- collections.Counter() now supports a subtract() method.
3628
Georg Brandlfee0f442010-05-22 21:26:21 +00003629- The functools module now has a total_ordering() class decorator to simplify
3630 the specification of rich comparisons.
Raymond Hettingera551f312010-04-04 18:34:45 +00003631
Georg Brandlfee0f442010-05-22 21:26:21 +00003632- The functools module also adds cmp_to_key() as a tool to transition old-style

Georg Brandlfee0f442010-05-22 21:26:21 +00003638- Issue #7279: Comparisons involving a Decimal signaling NaN now signal
3639 InvalidOperation instead of returning False. (Comparisons involving a quiet
3640 NaN are unchanged.) Also, Decimal quiet NaNs are now hashable; Decimal
3641 signaling NaNs remain unhashable.
Mark Dickinsone096e822010-04-02 10:17:07 +00003642
Georg Brandlfee0f442010-05-22 21:26:21 +00003643- Issue #2531: Comparison operations between floats and Decimal instances now
3644 return a result based on the numeric values of the operands; previously they
3645 returned an arbitrary result based on the relative ordering of id(float) and
3646 id(Decimal).
Mark Dickinson99d80962010-04-02 08:53:22 +00003647
Barry Warsawf7f2d6f2010-03-31 21:07:16 +00003648- Issue #8233: When run as a script, py_compile.py optionally takes a single
Georg Brandlfee0f442010-05-22 21:26:21 +00003649 argument `-` which tells it to read files to compile from stdin. Each line is
3650 read on demand and the named file is compiled immediately. (Original patch by
3651 Piotr Ożarowski).

Florent Xicluna58b65662010-03-30 16:29:03 +00003656- Backwards incompatible change: Unicode codepoints line tabulation (0x0B) and
3657 form feed (0x0C) are now considered linebreaks, as specified in Unicode
Georg Brandlfee0f442010-05-22 21:26:21 +00003658 Standard Annex #14. See issue #7643. http://www.unicode.org/reports/tr14/
Florent Xicluna22b24382010-03-30 08:24:06 +00003659
Georg Brandlfee0f442010-05-22 21:26:21 +00003660- Comparisons using one of <, <=, >, >= between a complex instance and a
3661 Fractions instance now raise TypeError instead of returning True/False. This
3662 makes Fraction <=> complex comparisons consistent with int <=> complex, float
3663 <=> complex, and complex <=> complex comparisons.

Antoine Pitrou513d9ae2010-03-22 19:59:46 +00003674- Issue #7512: shutil.copystat() could raise an OSError when the filesystem
Georg Brandlfee0f442010-05-22 21:26:21 +00003675 didn't support chflags() (for example ZFS under FreeBSD). The error is now
3676 silenced.
Antoine Pitrou513d9ae2010-03-22 19:59:46 +00003677
Florent Xicluna9e7a4c92010-03-22 16:07:38 +00003678- Issue #7703: ctypes supports both buffer() and memoryview(). The former is

4021 and add the additional members returned in an OSVERSIONINFOEX structure. The
4022 new members are service_pack_major, service_pack_minor, suite_mask, and

Georg Brandlba83f822010-03-14 09:50:54 +00004025- Issue #7561: Operations on empty bytearrays (such as ``int(bytearray())``)
4026 could crash in many places because of the ``PyByteArray_AS_STRING()`` macro
4027 returning NULL. The macro now returns a statically allocated empty string
4028 instead.

4038 strings,
4039 (2) a crash in dtoa.c that occurred in debug builds when parsing certain long
4040 numeric strings corresponding to subnormal values,
4041 (3) a memory leak for some values large enough to cause overflow, and
4042 (4) a number of flaws that could lead to incorrectly rounded results.

Georg Brandlba83f822010-03-14 09:50:54 +00004074 specified, rather than fall through to AF_PACKET (in the ``socket`` module).

Antoine Pitrouf3fa0742010-01-31 22:26:04 +00004080- Issue #6939: Fix file I/O objects in the `io` module to keep the original
Georg Brandlba83f822010-03-14 09:50:54 +00004081 file position when calling `truncate()`. It would previously change the file
4082 position to the given argument, which goes against the tradition of
Antoine Pitrouf3fa0742010-01-31 22:26:04 +00004083 ftruncate() and other truncation APIs. Patch by Pascal Chambon.
4084
Georg Brandlba83f822010-03-14 09:50:54 +00004085- Issue #7610: Reworked implementation of the internal ``zipfile.ZipExtFile``
4086 class used to represent files stored inside an archive. The new
4087 implementation is significantly faster and can be wrapped in a
4088 ``io.BufferedReader`` object for more speedups. It also solves an issue
4089 where interleaved calls to ``read()`` and ``readline()`` give wrong results.

Georg Brandlba83f822010-03-14 09:50:54 +00004100- Issue #7748: Since unicode values are supported for some metadata options in
4101 Distutils, the DistributionMetadata get_* methods will now return an utf-8
4102 encoded string for them. This ensures that the upload and register commands
4103 send the correct values to PyPI without any error.

Benjamin Peterson4f51baf2009-12-05 18:40:02 +00004172What's New in Python 2.7 alpha 2?
4173=================================

4178-----------------
4179
Georg Brandlba83f822010-03-14 09:50:54 +00004180- The ``__complex__()`` method is now looked up on the class of instances to
4181 make it consistent with other special methods.
Benjamin Petersonecdae192010-01-04 00:43:01 +00004182
Antoine Pitrou5b7139a2010-01-02 21:12:58 +00004183- Issue #7462: Implement the stringlib fast search algorithm for the `rfind`,
4184 `rindex`, `rsplit` and `rpartition` methods. Patch by Florent Xicluna.
4185
Mark Dickinson1b34d252010-01-01 17:27:30 +00004186- Issue #5080: A number of functions and methods previously produced a
Georg Brandlba83f822010-03-14 09:50:54 +00004187 DeprecationWarning when passed a float argument where an integer was expected.
4188 These functions and methods now raise TypeError instead. The majority of the
4189 effects of this change are in the extension modules, but some core functions
4190 and methods are affected: notably the 'chr', 'range' and 'xrange' builtins,
4191 and many unicode/str methods.
Mark Dickinson1b34d252010-01-01 17:27:30 +00004192

Amaury Forgeot d'Arc8645a5c2009-12-29 22:03:38 +00004201- Issue #7413: Passing '\0' as the separator to datetime.datetime.isoformat()
4202 used to drop the time part of the result.
4203
Georg Brandlba83f822010-03-14 09:50:54 +00004204- Issue #1811: Improve accuracy and cross-platform consistency for true division
4205 of integers: the result of a/b is now correctly rounded for ints a and b (at
4206 least on IEEE 754 platforms), and in particular does not depend on the
4207 internal representation of a long.
Mark Dickinson46572832009-12-27 14:55:57 +00004208
Georg Brandlba83f822010-03-14 09:50:54 +00004209- Issue #6108: ``unicode(exception)`` and ``str(exception)`` should return the
4210 same message when only ``__str__()`` (and not ``__unicode__()``) is overridden
4211 in the subclass.
Ezio Melottif84caf42009-12-24 22:25:17 +00004212

Ronald Oussoren92919a62009-12-24 13:30:58 +00004214 executables on OSX.
4215
Georg Brandlba83f822010-03-14 09:50:54 +00004216 These executables now work properly with the arch(1) command: ``arch -ppc
4217 python`` will start a universal binary version of python in PPC mode (unlike
4218 previous releases).
Ronald Oussoren92919a62009-12-24 13:30:58 +00004219
Georg Brandlba83f822010-03-14 09:50:54 +00004220- Issue #1680159: Unicode coercion during an 'in' operation no longer masks the
4221 underlying error when the coercion fails for the left hand operand.
R. David Murray0a0a1a82009-12-14 16:28:26 +00004222

Georg Brandlba83f822010-03-14 09:50:54 +00004232- Issue #6963: Added "maxtasksperchild" argument to ``multiprocessing.Pool``,
4233 allowing for a maximum number of tasks within the pool to be completed by the
4234 worker before that worker is terminated, and a new one created to replace it.

Antoine Pitrou80157252010-01-08 19:20:17 +00004240- Issue #7092: Remove py3k warning when importing cPickle. 2to3 handles
Georg Brandlba83f822010-03-14 09:50:54 +00004241 renaming of `cPickle` to `pickle`. The warning was annoying since there's no
4242 alternative to cPickle if you care about performance. Patch by Florent

Ezio Melotti569e61f2009-12-30 06:14:51 +00004262 Initial patch by Brian Curtin.
4263
Georg Brandlba83f822010-03-14 09:50:54 +00004264- Distutils now correctly identifies the build architecture as "x86_64" when

Benjamin Petersonddd392c2009-12-13 19:19:07 +00004277- Issue #7349: Make methods of file objects in the io module accept None as an
4278 argument where file-like objects (ie StringIO and BytesIO) accept them to mean
4279 the same as passing no argument.
4280
Georg Brandlba83f822010-03-14 09:50:54 +00004281- Issue #7348: ``StringIO.StringIO.readline(-1)`` now acts as if it got no

4305 ``PyArg_VaParseTupleAndKeywords()`` and ``PyArg_Parse()`` no longer accept
4306 float arguments for integer format codes (other than 'L'): previously an

Georg Brandlba83f822010-03-14 09:50:54 +00004374- Issue #7117: ``repr(x)`` for a float x returns a result based on the shortest
4375 decimal string that's guaranteed to round back to x under correct rounding
4376 (with round-half-to-even rounding mode). Previously it gave a string based on
4377 rounding x to 17 decimal digits. repr(x) for a complex number behaves
4378 similarly. On platforms where the correctly-rounded strtod and dtoa code is
4379 not supported (see below), repr is unchanged.
Mark Dickinsonb678de82009-11-19 18:41:49 +00004380
Georg Brandlba83f822010-03-14 09:50:54 +00004381- Issue #7117: On almost all platforms: float-to-string and string-to-float
4382 conversions within Python are now correctly rounded. Places these conversions
4383 occur include: str for floats and complex numbers; the float and complex
4384 constructors; old-style and new-style numeric formatting; serialization and
4385 deserialization of floats and complex numbers using marshal, pickle and json;
4386 parsing of float and imaginary literals in Python code; Decimal-to-float
4387 conversion.
Mark Dickinsonb678de82009-11-19 18:41:49 +00004388
Georg Brandlba83f822010-03-14 09:50:54 +00004389 The conversions use a Python-adapted version of David Gay's well-known dtoa.c,
4390 providing correctly-rounded strtod and dtoa C functions. This code is
4391 supported on Windows, and on Unix-like platforms using gcc, icc or suncc as
4392 the C compiler. There may be a small number of platforms on which correct
4393 operation of this code cannot be guaranteed, so the code is not used: notably,
4394 this applies to platforms where the C double format is not IEEE 754 binary64,
4395 and to platforms on x86 hardware where the x87 FPU is set to 64-bit precision
4396 and Python's configure script is unable to determine how to change the FPU
4397 precision. On these platforms conversions use the platform strtod and dtoa,
4398 as before.
Mark Dickinsonb678de82009-11-19 18:41:49 +00004399
Georg Brandlba83f822010-03-14 09:50:54 +00004400- Issue #7117: Backport round implementation from Python 3.x. ``round()`` now
4401 uses the correctly-rounded string <-> float conversions described above (when
4402 available), and so produces correctly rounded results that will display nicely
4403 under the float repr. There are two related small changes: (1) round now
4404 accepts any class with an ``__index__()`` method for its second argument (but
4405 no longer accepts floats for the second argument), and (2) an excessively
4406 large second integer argument (e.g., ``round(1.234, 10**100)``) no longer

4634 internal representation of integers, for performance reasons. Base 2**30 is
4635 enabled by default on 64-bit machines. Add --enable-big-digits option to
4636 configure, which overrides the default. Add sys.long_info structseq to
4637 provide information about the internal format.

4757
Georg Brandlba83f822010-03-14 09:50:54 +00004758- Issue #4233: Changed semantic of ``_fileio.FileIO``'s ``close()`` method on
4759 file objects with closefd=False. The file descriptor is still kept open but
4760 the file object behaves like a closed file. The ``FileIO`` object also got a

Georg Brandlba83f822010-03-14 09:50:54 +00004784- On windows, ``os.chdir()`` given unicode was not working if
4785 GetCurrentDirectoryW returned a path longer than MAX_PATH. (But It's doubtful
4786 this code path is really executed because I cannot move to such directory on
4787 win2k)

Georg Brandlba83f822010-03-14 09:50:54 +00004789- Issue #4069: When ``set.remove(element)`` is used with a set element, the
4790 element is temporarily replaced with an equivalent frozenset. But the
4791 eventual KeyError would always report the empty ``frozenset()`` as the missing

4813 PyUnicode_DecodeUTF8() once, remember the result and output it in a second
4814 step. This avoids problems with counting UTF-8 bytes that ignores the effect
4815 of using the replace error handler in PyUnicode_DecodeUTF8().

Walter Dörwald726ba8e2009-05-06 14:32:35 +00004817- Issue #3739: The unicode-internal encoder now reports the number of characters

Amaury Forgeot d'Arc05e34492008-09-10 22:04:45 +00006193- Issue #3743: In a few places, PY_FORMAT_SIZE_T was incorrectly used with
6194 PyString_FromFormat or PyErr_Format to display size_t values. The macro
6195 PY_FORMAT_SIZE_T is designed to select the correct format for the OS
6196 ``printf`` function, whereas PyString_FromFormat has an independent
6197 implementation and uses "%zd" on all platforms for size_t values.
6198 This makes a difference on win64, where ``printf`` needs "%Id" to display
6199 64bit values.

Antoine Pitrou0668c622008-08-26 22:42:08 +00006219 match Python 2.5 speed despite the __instancecheck__ / __subclasscheck__
6220 mechanism. In the process, fix a bug where isinstance() and issubclass(),

6222 __instancecheck__ / __subclasscheck__ on the tuple rather than on each
6223 type object.

Brett Cannon1eaf0742008-09-02 01:25:16 +00006294 warnings.catch_warnings() along with some API cleanup. Expanding the tests
6295 for catch_warnings() also led to an improvement in the raising of a
6296 DeprecationWarning related to warnings.warn_explicit().
6297
Benjamin Peterson973e6c22008-09-01 23:12:58 +00006298- The deprecation warnings for the old camelCase threading API were removed.

6320
Amaury Forgeot d'Arc293924b2008-09-02 23:19:56 +00006321- Issue #2975: When compiling several extension modules with Visual Studio 2008
6322 from the same python interpreter, some environment variables would grow
6323 without limit.
6324
Benjamin Peterson37346b22008-08-23 20:27:43 +00006325- Issue #3643: Added a few more checks to _testcapi to prevent segfaults by
6326 exploitation of poor argument checking.
6327
Gerhard Häringef2276b2008-09-12 13:54:06 +00006328- sqlite3: Changed docstring of iterdump() to mark method as "Non-standard".

Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00006362What's New in Python 2.6 beta 3?
6363================================
6364
Barry Warsaw07a4a382008-08-21 01:15:08 +00006365*Release date: 20-Aug-2008*
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00006366
6367Core and Builtins
6368-----------------
6369
Guido van Rossumf8402962008-08-20 15:01:50 +00006370- Issue #1878: Remove Py_TPFLAGS_HAVE_VERSION_TAG from
6371 Py_TPFLAGS_DEFAULT when not building the core. This means 3rd party
6372 extensions do not automatically benefit from the class attribute
6373 cache; they will have to explicitly add Py_TPFLAGS_HAVE_VERSION_TAG
6374 to their tp_flags field if they care. This is a backwards
6375 compatibility feature; in 3.0, all types will use the cache by
6376 default.
6377
Benjamin Petersonf647dc12008-08-20 01:27:30 +00006378- Keyword arguments can now follow starred arguments. (``f(a, *args,
6379 keyword=23)`` is now valid syntax.)
6380
Thomas Heller0ad5ae02008-08-19 19:25:04 +00006381- ctypes function pointers that are COM methods have a boolean True
6382 value again.
6383
Martin v. Löwisf91d46a2008-08-12 14:49:50 +00006384- Issue #3139: Make buffer-interface thread-safe wrt. PyArg_ParseTuple,
6385 by denying s# to parse objects that have a releasebuffer procedure,
6386 and introducing s*.
6387
Georg Brandl1e13ea92008-08-11 09:07:59 +00006388- Issue #3537: Fix an assertion failure when an empty but presized dict
6389 object was stored in the freelist.
6390
Mark Dickinsonb6467572008-08-04 21:30:09 +00006391- Issue #1481296: Make long(float('nan')) and int(float('nan')) raise
6392 ValueError consistently across platforms.
6393
Amaury Forgeot d'Arc39fd6722008-07-31 21:28:03 +00006394- Issue #3479: On platforms where sizeof(int) is smaller than sizeof(long)
6395 (64bit Unix, for example), unichr() would truncate its argument and return
6396 u'\x00' for unichr(2**32). Now it properly raises an OverflowError.
6397
Neal Norwitze7d8be82008-07-31 17:17:14 +00006398- Apply security patches from Apple.
6399
Amaury Forgeot d'Arc246daed2008-07-31 00:42:16 +00006400- Issue #2542: Now that issubclass() may call arbitrary code, ensure that
6401 PyErr_ExceptionMatches returns 0 when an exception occurs there.
6402
Antoine Pitrou92f82162008-07-25 22:22:08 +00006403- Issue #1819: function calls with several named parameters are now on
6404 average 35% faster (as measured by pybench).
6405
Amaury Forgeot d'Arce4921fe2008-07-21 22:00:38 +00006406- Issue #2378: An unexpected UnboundLocalError or NameError could appear when
6407 the python debugger steps into a class statement: the free variables (local
6408 variables defined in an outer scope) would be deleted from the outer scope.
6409
Gregory P. Smith0470bab2008-07-22 04:46:32 +00006410- Issue #2620: Overflow checking when allocating or reallocating memory
6411 was not always being done properly in some python types and extension
6412 modules. PyMem_MALLOC, PyMem_REALLOC, PyMem_NEW and PyMem_RESIZE have
6413 all been updated to perform better checks and places in the code that
6414 would previously leak memory on the error path when such an allocation
6415 failed have been fixed.

6418-------
6419
Hirokazu Yamamoto838c79f2008-08-20 13:14:07 +00006420- Issue #3612: Added some missing basic types in ctypes.wintypes.
6421
Benjamin Petersone977ad42008-08-20 01:42:01 +00006422- The methods ``is_in_tuple()``, ``is_vararg()``, and ``is_keywordarg()`` of
6423 symtable.Symbol have been deprecated for removal in 3.0 and the next release.
6424
Amaury Forgeot d'Arc351ffb82008-08-18 19:23:47 +00006425- Issue #2234: distutils failed for some versions of the cygwin compiler. The
6426 version reported by these tools does not necessarily follow the python
6427 version numbering scheme, so the module is less strict when parsing it.
6428
Nick Coghlanf70385a2008-08-18 12:42:46 +00006429- Issue #2235: Added Py3k warnings for types which will become unhashable
6430 under the stricter __hash__ inheritance rules in 3.0. Several types
6431 which did not meet the rules for hash invariants and were already
6432 unhashable in 3.0 have now been explicitly flagged as unhashable in
6433 2.6 as well (collections.Mapping, collections.Set, unittest.TestSuite,
6434 xml.dom.minidom.NamedNodeMap, numbers.Number, UserList.UserList)
6435
Brett Cannon88f801d2008-08-18 00:46:22 +00006436- Update __all__ for cookielib, csv, os, urllib2, and weakref to include things

6444
Hirokazu Yamamoto41a81eb2008-08-17 13:10:46 +00006445- Issue #3575: Incremental decoder's decode function now takes bytearray
6446 by using 's*' instead of 't#'.
6447
Mark Dickinson3e4caeb2009-02-21 20:27:01 +00006448- Issue #2222: Fixed reference leak when occurred os.rename()
Hirokazu Yamamoto7f30a682008-08-17 09:46:56 +00006449 fails unicode conversion on 2nd parameter. (windows only)
6450
Georg Brandl222e2082010-08-01 22:27:39 +00006451- Issue #2464: urllib2 now supports a malformation in the URL received
Facundo Batista94f243a2008-08-17 03:38:39 +00006452 in a redirect.
6453

Brett Cannon721b1452008-08-16 22:00:27 +00006455 BaseHTTPServer, cgi (and rfc822), httplib.
Brett Cannonabe423e2008-08-16 21:47:07 +00006456
Facundo Batistaeb90b782008-08-16 14:44:07 +00006457- Issue #2776: fixed small issue when handling an URL with double slash
6458 after a 302 response in the case of not going through a proxy.
6459
Antoine Pitroub90a8be2008-08-15 21:03:21 +00006460- Issue #2676: in the email package, content-type parsing was hanging on
6461 pathological input because of quadratic or exponential behaviour of a
6462 regular expression.
6463
Antoine Pitrou11ec65d2008-08-14 21:04:30 +00006464- Issue #3476: binary buffered reading through the new "io" library is now
6465 thread-safe.
6466
Brett Cannonbf3157b2008-08-14 05:00:03 +00006467- Silence the DeprecationWarning of rfc822 when it is imported by mimetools
6468 since mimetools itself is deprecated. Because modules are cached, all
6469 subsequent imports of rfc822 will not raise a visible DeprecationWarning.
6470
Antoine Pitrou9fcd4b32008-08-11 17:21:36 +00006471- Issue #3134: shutil referenced undefined WindowsError symbol.
6472
Robert Schuppenies14646332008-08-10 11:01:53 +00006473- Issue #1342811: Fix leak in Tkinter.Menu.delete. Commands associated to
6474 menu entries were not deleted.
6475
Brett Cannon83e81842008-08-09 23:30:55 +00006476- Copied the implementation of reduce() to _functools.reduce() to have a
6477 version that did not raise a DeprecationWarning under -3.
6478
Antoine Pitrou76b8bee2008-08-09 17:27:23 +00006479- Issue #3205: When iterating over a BZ2File fails allocating memory, raise
6480 a MemoryError rather than silently stop the iteration.
6481
Guido van Rossum59ce9012008-08-09 14:55:34 +00006482- Issue #3487: sre "bytecode" validator. Passing invalid "re-bytecode"
6483 to _sre.compile() will now be rejected. This should not affect anybody
6484 since the re.compile() function never generates invalid re-bytecode.
6485
Skip Montanaroa032bf42008-08-08 22:52:51 +00006486- Issue #3436: Make csv.DictReader's fieldnames attribute a property so that
6487 upon first access it can be automatically initialized from the csv file if
6488 it wasn't initialized during instantiation.
6489
Brett Cannon3aa2a492008-08-06 22:28:09 +00006490- Issue #2338: Create imp.reload() to help with transitioning to Python 3.0 as
6491 the reload() built-in has been removed.
6492
Brett Cannon7e30b672008-08-04 21:52:25 +00006493- Changed code in the following modules/packages to remove warnings raised
Brett Cannonc1b76e42008-08-09 23:06:16 +00006494 while running under the ``-3`` flag: aifc, asynchat, asyncore, bdb, bsddb,

Antoine Pitroude781a42008-08-09 12:43:23 +00006505 asking for a specific length. This problem only affected files opened
6506 using the new "io" module, not the built-in open() function.
Benjamin Peterson01a24322008-07-28 23:35:27 +00006507

6533 mode 0600 rather than 000 under Unix.
6534

Raymond Hettingere3ae6552008-06-20 04:18:15 +00006556What's New in Python 2.6 beta 2?
6557================================
6558
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00006559*Release date: 17-Jul-2008*
6560
Raymond Hettingere3ae6552008-06-20 04:18:15 +00006561Core and Builtins
6562-----------------
6563
Georg Brandl3e483f62008-07-16 22:57:41 +00006564- Issue #3156: Fix inconsistent behavior of the bytearray type: all
6565 its methods now allow for items objects that can be converted to
6566 an integer using operator.index().
6567
Mark Dickinson64b7e502008-07-16 09:40:03 +00006568- Issue #3360: Fix incorrect parsing of '020000000000.0', which
6569 produced a ValueError instead of giving the correct float.
6570
Eric Smitha5fa5a22008-07-16 00:11:49 +00006571- Issue #3083: Add alternate (#) formatting for bin, oct, hex output
6572 for str.format(). This adds the prefix 0b, 0o, or 0x, respectively.
6573
Mark Dickinson7103aa42008-07-15 19:08:33 +00006574- Issue #3008: the float type has a new instance method 'float.hex'
6575 and a new class method 'float.fromhex' to convert floating-point
6576 numbers to and from hexadecimal strings, respectively.
6577
Nick Coghlan6d6bd442008-07-15 15:40:22 +00006578- Issue #2235: __hash__ is once again inherited by default. To allow
6579 collections.Hashable to remain meaningful in the presence of the
6580 default hash implementation (object.__hash__), it is now possible
6581 to explicit block inheritance of hash by setting __hash__=None at
6582 the Python level, or tp_hash=PyObject_HashNotImplemented at the C
6583 level.
6584
Nick Coghlanb028f502008-07-13 14:52:36 +00006585- Issue #3221: Issue a RuntimeWarning instead of raising SystemError if
6586 the parent module cannot be found while performing an absolute import.
6587 This means that an incorrectly defined __package__ attribute will
6588 now only prevent relative imports in that module rather than causing
6589 all imports from that module to fail.
6590
Nick Coghlan14ff9942008-07-08 14:21:42 +00006591- Issue #2517: Allow unicode messages in Exceptions again by correctly
6592 bypassing the instance dictionary when looking up __unicode__ on
6593 new-style classes.
6594
Amaury Forgeot d'Arcbdd941f2008-07-01 20:38:04 +00006595- Issue #3242: Fix a crash inside the print statement, if sys.stdout is
6596 set to a custom object whose write() method happens to install
6597 another file in sys.stdout.
6598
Amaury Forgeot d'Arc1f40c8a2008-06-30 22:42:40 +00006599- Issue #3088: Corrected a race condition in classes derived from
6600 threading.local: the first member set by a thread could be saved in
6601 another thread's dictionary.
6602
Mark Dickinson1ec2fcd2008-06-20 14:53:43 +00006603- Issue #3004: Minor change to slice.indices(): the start and stop
6604 arguments are now treated identically, making the behaviour easier
6605 to describe and understand. For example, slice(None, -10,
6606 1).indices(9) now returns (0, 0, 1) instead of (0, -1, 1), and
6607 slice(None, 10, -1).indices(10) returns (9, 9, -1) instead of (9,
6608 10, -1).
6609
Georg Brandl278fc502008-07-19 12:46:12 +00006610- Issue #3219: Calling a function with repeated keyword arguments,
6611 f(a=2, a=23), would not cause a syntax error. This was a regression
6612 from 2.4 caused by the switch to the new compiler.
Benjamin Peterson175e4d92008-07-01 19:34:52 +00006613
Georg Brandl278fc502008-07-19 12:46:12 +00006614- Issue #2862: Make int and float freelist management consistent with
6615 other freelists. Changes their CompactFreeList apis into
6616 ClearFreeList apis and calls them via gc.collect().
Gregory P. Smith2fe77062008-07-06 03:35:58 +00006617
Brett Cannon8bb8fa52008-07-02 01:57:08 +00006618Library
6619-------
6620
Thomas Heller57adf222008-08-14 19:10:48 +00006621- Issue #3554: ctypes.string_at and ctypes.wstring_at did call Python
6622 api functions without holding the GIL, which could lead to a fatal
6623 error when they failed.
6624
Martin v. Löwisaabf4042008-08-02 07:20:25 +00006625- Issue #799428: Fix Tkinter.Misc._nametowidget to unwrap Tcl command objects.
6626

6632
Jesse Noller13e9d582008-07-16 14:32:36 +00006633- Issue #3125: Remove copy_reg in multiprocessing and replace it with
6634 ForkingPickler.register() to resolve conflict with ctypes.
6635
Vinay Sajip51e65192008-07-18 09:01:10 +00006636- Issue #3090: Fixed ARCHFLAGS parsing on OS/X
Jesse Noller13e9d582008-07-16 14:32:36 +00006637
Thomas Heller880f5292008-07-15 19:39:38 +00006638- Issue #3313: Fixed a crash when a failed dlopen() call does not set
6639 a valid dlerror() message.
6640
Thomas Heller2bad6572008-07-15 17:19:50 +00006641- Issue #3258: Fixed a crash when a ctypes POINTER type to an
6642 incomplete structure was created.
6643
Brett Cannon3d0b9f02008-07-13 01:15:07 +00006644- Issue #3339: dummy_thread.acquire() should not return None.
6645
Raymond Hettingerb01713e2008-07-10 14:34:57 +00006646- Issue #3285: Fractions from_float() and from_decimal() accept Integral arguments.
6647
Andrew M. Kuchlingcc3f2b12008-07-10 14:43:31 +00006648- Issue #3301: Bisect module behaved badly when lo was negative.
Raymond Hettinger3cd1e422008-07-10 14:03:19 +00006649
Amaury Forgeot d'Arc0f7cddc2008-07-06 21:34:39 +00006650- Issue #839496: SimpleHTTPServer used to open text files in text mode. This is
6651 both unnecessary (HTTP allows text content to be sent in several forms) and
Andrew M. Kuchlingcc3f2b12008-07-10 14:43:31 +00006652 wrong because the actual transmitted size could differ from the
Amaury Forgeot d'Arc0f7cddc2008-07-06 21:34:39 +00006653 content-length. The problem had been corrected in the 2.4 branch, but never
6654 merged into trunk.
6655
Georg Brandle78fbcc2008-07-05 10:13:36 +00006656- Issue #2663: add filtering capability to shutil.copytree().

6659
6660- Issue #1526: Allow more than 64k files to be added to Zip64 file.
6661
6662- Issue #1746: Correct handling of zipfile archive comments (previously
6663 archives with comments over 4k were flagged as invalid). Allow writing
Vinay Sajip51e65192008-07-18 09:01:10 +00006664 Zip files with archives by setting the 'comment' attribute of a ZipFile.
Martin v. Löwis8c436412008-07-03 12:51:14 +00006665
Vinay Sajip51e65192008-07-18 09:01:10 +00006666- Issue #449227: The rlcompleter module now adds "(" to callable objects
Andrew M. Kuchlingcc3f2b12008-07-10 14:43:31 +00006667 when completed.
Facundo Batista66c52772008-07-02 16:52:55 +00006668
Nick Coghlanc060b0e2008-07-02 13:09:19 +00006669- Issue #3190: Pydoc now hides the automatic module attribute __package__ (the
6670 handling is now the same as that of other special attributes like __name__).
6671
Brett Cannon8bb8fa52008-07-02 01:57:08 +00006672- Issue #2885 (partial): The urllib.urlopen() function has been deprecated for
6673 removal in Python 3.0 in favor of urllib2.urlopen().

6685
Gregory P. Smithdb3409c2008-07-17 03:13:05 +00006686- Issue #874900: after an os.fork() call the threading module state is cleaned

Georg Brandl3ee81df2008-05-17 18:14:43 +00007124- Issue #1631171: Re-implement the 'warnings' module in C (the
7125 original Python code has been kept as backup). This will allow for
7126 using the 'warning's machinery in such places as the parser where
7127 use of pure Python code is not possible. Both the ``showarning()``
7128 and ``formatwarning()`` gain an optional 'line' argument which is
7129 not called by default for backwards-compatibility reasons. Setting
7130 ``warnings.showwarning()`` to an implementation that lacks support
7131 for the ``line`` argument will raise a DeprecationWarning.

Georg Brandl3ee81df2008-05-17 18:14:43 +00007194- Issue #2550: The approach used by client/server code for obtaining
7195 ports to listen on in network-oriented tests has been refined in an
7196 effort to facilitate running multiple instances of the entire
7197 regression test suite in parallel without issue.
7198 test_support.bind_port() has been fixed such that it will always
7199 return a unique port -- which wasn't always the case with the
7200 previous implementation, especially if socket options had been set
7201 that affected address reuse (i.e. SO_REUSEADDR, SO_REUSEPORT). The
7202 new implementation of bind_port() will actually raise an exception
7203 if it is passed an AF_INET/SOCK_STREAM socket with either the
7204 SO_REUSEADDR or SO_REUSEPORT socket option set. Furthermore, if
7205 available, bind_port() will set the SO_EXCLUSIVEADDRUSE option on
7206 the socket it's been passed. This currently only applies to
7207 Windows. This option prevents any other sockets from binding to the
7208 host/port we've bound to, thus removing the possibility of the
7209 'non-deterministic' behaviour, as Microsoft puts it, that occurs
7210 when a second SOCK_STREAM socket binds and accepts to a host/port
7211 that's already been bound by another socket. The optional preferred
7212 port parameter to bind_port() has been removed. Under no
7213 circumstances should tests be hard coding ports!
7214
7215 test_support.find_unused_port() has also been introduced, which will
7216 pass a temporary socket object to bind_port() in order to obtain an
7217 unused port. The temporary socket object is then closed and
7218 deleted, and the port is returned. This method should only be used
7219 for obtaining an unused port in order to pass to an external program
7220 (i.e. the -accept [port] argument to openssl's s_server mode) or as
7221 a parameter to a server-oriented class that doesn't give you direct
7222 access to the underlying socket used.
7223
7224 Finally, test_support.HOST has been introduced, which should be used
7225 for the host argument of any relevant socket calls (i.e. bind and
7226 connect).
Trent Nelsone41b0062008-04-08 23:47:30 +00007227
7228 The following tests were updated to following the new conventions:
Georg Brandl3ee81df2008-05-17 18:14:43 +00007229 test_socket, test_smtplib, test_asyncore, test_ssl, test_httplib,
Trent Nelsone41b0062008-04-08 23:47:30 +00007230 test_poplib, test_ftplib, test_telnetlib, test_socketserver,
7231 test_asynchat and test_socket_ssl.
7232
Georg Brandl3ee81df2008-05-17 18:14:43 +00007233 It is now possible for multiple instances of the regression test
7234 suite to run in parallel without issue.

7390 processor information on Windows XP and later. As a result,
Marc-André Lemburga1867752008-03-20 18:08:00 +00007391 platform.machine() and platform.processor() will report this
7392 information as well.

Eric Smitha73fbe72008-02-23 03:09:44 +00007513- Added the future_builtins module, which contains hex() and oct().
7514 These are the PEP 3127 version of these functions, designed to be
7515 compatible with the hex() and oct() builtins from Python 3.0. They
7516 differ slightly in their output formats from the existing, unchanged
7517 Python 2.6 builtins. The expected usage of the future_builtins
7518 module is:
7519 from future_builtins import hex, oct
7520
Eric Smith7ef40bf2008-02-20 23:34:22 +00007521- Issue #1600: Modifed PyOS_ascii_formatd to use at most 2 digit
7522 exponents for exponents with absolute value < 100. Follows C99
7523 standard. This is a change on Windows, which would use 3 digits.
7524 Also, added 'n' to the formats that PyOS_ascii_formatd understands,
7525 so that any alterations it does to the resulting string will be
7526 available in stringlib/formatter.h (for float.__format__).
7527
Eric Smith5a3c1352008-02-19 13:21:56 +00007528- Implemented PEP 3101, Advanced String Formatting. This adds a new
7529 builtin format(); a format() method for str and unicode; a
7530 __format__() method to object, str, unicode, int, long, float, and
7531 datetime; the class string.Formatter; and the C API
7532 PyObject_Format().
7533
Georg Brandl3ee81df2008-05-17 18:14:43 +00007534- Fixed several potential crashes, all caused by specially crafted
7535 __del__ methods exploiting objects in temporarily inconsistent
7536 state.
Amaury Forgeot d'Arc632fad32008-02-16 20:55:24 +00007537
Vinay Sajipb7edfc42008-04-02 21:10:23 +00007538- Issue #2115: Important speedup in setting __slot__ attributes. Also
Georg Brandl3ee81df2008-05-17 18:14:43 +00007539 prevent a possible crash: an Abstract Base Class would try to access
7540 a slot on a registered virtual subclass.
Amaury Forgeot d'Arc60d6c7f2008-02-15 21:22:45 +00007541

Georg Brandl3ee81df2008-05-17 18:14:43 +00007545- Clear all free lists during a gc.collect() of the highest generation
7546 in order to allow pymalloc to free more arenas. Python may give back
7547 memory to the OS earlier.
Christian Heimes3b718a72008-02-14 12:47:33 +00007548
Georg Brandl3ee81df2008-05-17 18:14:43 +00007549- Issue #2045: Fix an infinite recursion triggered when printing a
7550 subclass of collections.defaultdict, if its default_factory is set
7551 to a bound method.
Amaury Forgeot d'Arcb01aa432008-02-08 00:56:02 +00007552
Christian Heimesf75dbef2008-02-08 00:11:31 +00007553- Fixed a minor memory leak in dictobject.c. The content of the free
7554 list was not freed on interpreter shutdown.
7555
Georg Brandl21e99f42010-03-07 15:23:59 +00007556- Limit free list of method and built-in function objects to 256
Georg Brandl3ee81df2008-05-17 18:14:43 +00007557 entries each.
Christian Heimes6075a822008-02-06 12:44:34 +00007558
Georg Brandl3ee81df2008-05-17 18:14:43 +00007559- Patch #1953: Added ``sys._compact_freelists()`` and the C API
7560 functions ``PyInt_CompactFreeList`` and ``PyFloat_CompactFreeList``
Christian Heimes422051a2008-02-04 18:00:12 +00007561 to compact the internal free lists of pre-allocted ints and floats.
7562
Georg Brandl3ee81df2008-05-17 18:14:43 +00007563- Issue #1983: Fixed return type of fork(), fork1() and forkpty()
7564 calls. Python expected the return type int but the fork familie
7565 returns pi_t.
Christian Heimes951cc0f2008-01-31 23:08:23 +00007566
Georg Brandl3ee81df2008-05-17 18:14:43 +00007567- Issue #1678380: Fix a bug that identifies 0j and -0j when they

Georg Brandl3ee81df2008-05-17 18:14:43 +00007579- Patch #1473257: generator objects gain a gi_code attribute. This is
7580 the same object as the func_code attribute of the function that
7581 produced the generator.
Georg Brandl0cdf9a32008-01-26 14:14:20 +00007582
Georg Brandl3ee81df2008-05-17 18:14:43 +00007583- Issue #1920: "while 0" statements were completely removed by the
7584 compiler, even in the presence of an "else" clause, which is
7585 supposed to be run when the condition is false. Now the compiler
7586 correctly emits bytecode for the "else" suite.
Amaury Forgeot d'Arc31eaafe2008-01-24 22:59:25 +00007587
Guido van Rossumeead05f2008-01-24 18:21:02 +00007588- A few crashers fixed: weakref_in_del.py (issue #1377858);
7589 loosing_dict_ref.py (issue #1303614, test67.py);
7590 borrowed_ref_[34].py (not in tracker).
7591

7595
Georg Brandl3ee81df2008-05-17 18:14:43 +00007596- Issue #1915: Python compiles with --enable-unicode=no again. However
Christian Heimes082c9b02008-01-23 14:20:50 +00007597 several extension methods and modules do not work without unicode
7598 support.
7599
Georg Brandl26543b12008-01-21 18:36:51 +00007600- Issue #1882: when compiling code from a string, encoding cookies in the
7601 second line of code were not always recognized correctly.
7602
Georg Brandl14404b62008-01-19 19:27:05 +00007603- Issue #1679: "0x" was taken as a valid integer literal.
7604
Georg Brandl6caad7d2008-01-26 14:19:22 +00007605- Issue #1865: ``bytes`` as an alias for ``str`` and b"" as an alias "" were
Christian Heimes288e89a2008-01-18 18:24:07 +00007606 added.
7607
Christian Heimesc94e2b52008-01-14 04:13:37 +00007608- sys.float_info / PyFloat_GetInfo: The floating point information
7609 object was converted from a dict to a specialized structseq object.
7610
Georg Brandl3ee81df2008-05-17 18:14:43 +00007611- Patch #1816: Added sys.flags structseq. It exposes the status of
7612 most command line arguments and PYTHON* environment variables.
Christian Heimesf31b69f2008-01-14 03:42:48 +00007613
Georg Brandl3ee81df2008-05-17 18:14:43 +00007614- Objects/structseq.c: Implemented new structseq representation. The
7615 patch makes structseqs (e.g. the return value of os.stat) more
7616 readable.

7625
Georg Brandl3ee81df2008-05-17 18:14:43 +00007626- Patch #602345: Add -B command line option, PYTHONDONTWRITEBYTECODE
7627 envvar and sys.dont_write_bytecode attribute. All these can be set
7628 to forbid Python to attempt to write compiled bytecode files.
Georg Brandl2da0fce2008-01-07 17:09:35 +00007629
Georg Brandl3ee81df2008-05-17 18:14:43 +00007630- Improve some exception messages when Windows fails to load an
7631 extension module. Now we get for example '%1 is not a valid Win32
7632 application' instead of 'error code 193'.

Christian Heimes0a8143f2007-12-18 23:22:54 +00007639- Issue #1635: Platform independent creation and representation of NaN
Georg Brandl3ee81df2008-05-17 18:14:43 +00007640 and INF. float("nan"), float("inf") and float("-inf") now work on
7641 every platform with IEEE 754 semantics.

Georg Brandl3ee81df2008-05-17 18:14:43 +00007643- Compiler now generates simpler and faster code for dictionary
7644 literals. The oparg for BUILD_MAP now indicates an estimated
7645 dictionary size. There is a new opcode, STORE_MAP, for adding
7646 entries to the dictionary.

7676 file can now be directly executed by passing their name to the
7677 interpreter. The directory/zipfile is automatically inserted as the
7678 first entry in sys.path.

Georg Brandl3ee81df2008-05-17 18:14:43 +00007680- Issue #1265: Fix a problem with sys.settrace, if the tracing
7681 function uses a generator expression when at the same time the
7682 executed code is closing a paused generator.
Amaury Forgeot d'Arc0d75f092007-11-13 21:54:28 +00007683

7689
Georg Brandl21e99f42010-03-07 15:23:59 +00007690- The enumerate() built-in function is no longer bounded to sequences
Georg Brandl3ee81df2008-05-17 18:14:43 +00007691 smaller than LONG_MAX. Formerly, it raised an OverflowError. Now,
7692 automatically shifts from ints to longs.
Raymond Hettinger8f669372007-10-03 21:18:11 +00007693
Georg Brandl3ee81df2008-05-17 18:14:43 +00007694- Issue #1686386: Tuple's tp_repr did not take into account the
7695 possibility of having a self-referential tuple, which is possible
7696 from C code. Nor did object's tp_str consider that a type's tp_str
7697 could do something that could lead to an inifinite recursion.
7698 Py_ReprEnter() and Py_EnterRecursiveCall(), respectively, fixed the
7699 issues.
Brett Cannon0b14f242007-09-30 19:45:10 +00007700
Georg Brandl3ee81df2008-05-17 18:14:43 +00007701- Issue #1164: It was possible to trigger deadlock when using the
7702 'print' statement to write to a file since the GIL was not released
7703 as needed. Now PyObject_Print() does the right thing along with
7704 various tp_print implementations of the built-in types and those in
7705 the collections module.
Brett Cannon01531592007-09-17 03:28:34 +00007706
Georg Brandl3ee81df2008-05-17 18:14:43 +00007707- Issue #1147: Exceptions were directly allowing string exceptions in

7709 allowed.

Brett Cannona0c05512007-09-10 21:38:27 +00007713
Brett Cannon1e534b52007-09-07 04:18:30 +00007714- Issue #1202533: Fix infinite recursion calls triggered by calls to
Georg Brandl3ee81df2008-05-17 18:14:43 +00007715 PyObject_Call() never calling back out to Python code to trigger
7716 recursion depth updates/checks. Required the creation of a static
7717 RuntimeError instance in case normalizing an exception put the
7718 recursion check value past its limit. Fixes crashers
7719 infinite_rec_(1|2|4|5).py.
Brett Cannon1e534b52007-09-07 04:18:30 +00007720

Neal Norwitz0ac60192007-05-27 04:08:54 +00007734- Add new attribute names for function objects. All the func_* become
Georg Brandl3ee81df2008-05-17 18:14:43 +00007735 __*__ attributes. (Some already existed, e.g., __doc__ and
7736 __name__.)
Neal Norwitz0ac60192007-05-27 04:08:54 +00007737
Neal Norwitz8b2bfbc2007-05-23 06:35:32 +00007738- Add -3 option to the interpreter to warn about features that are
7739 deprecated and will be changed/removed in Python 3.0.
7740
Georg Brandl2134e752007-05-21 20:34:16 +00007741- Patch #1686487: you can now pass any mapping after '**' in function
7742 calls.
7743
Collin Winter62903052007-05-18 23:11:24 +00007744- except clauses may now be spelled either "except E, target:" or
Georg Brandl3ee81df2008-05-17 18:14:43 +00007745 "except E as target:". This is to provide forwards compatibility
7746 with Python 3.0.

Vinay Sajip8549ce32007-05-06 17:53:37 +00007753- When __slots__ are set to a unicode string, make it work the same as
Neal Norwitzcbd9ee62007-04-14 05:25:50 +00007754 setting a plain string, ie don't expand to single letter identifiers.
7755
Raymond Hettinger13936692007-04-11 18:40:58 +00007756- Request #1191699: Slices can now be pickled.
7757
Raymond Hettinger4db5fe92007-04-12 04:10:00 +00007758- Request #1193128: str.translate() now allows a None argument for
7759 translations that only remove characters without re-mapping the
7760 remaining characters.
7761
Georg Brandl5cb76c12007-03-21 09:00:39 +00007762- Patch #1682205: a TypeError while unpacking an iterable is no longer

7766
Guido van Rossum143b5642007-03-23 04:58:42 +00007767- Bug #1683368: The object.__init__() and object.__new__() methods are
7768 now stricter in rejecting excess arguments. The only time when
7769 either allows excess arguments is when it is not overridden and the
7770 other one is. For backwards compatibility, when both are
7771 overridden, it is a deprecation warning (for now; maybe a Py3k
Guido van Rossum234b1ff2007-03-23 19:39:01 +00007772 warning later). Also, type.__init__() insists on the same signature
7773 as supported by type.__new__().
Guido van Rossum143b5642007-03-23 04:58:42 +00007774
Georg Brandl3ee81df2008-05-17 18:14:43 +00007775- Patch #1675423: PyComplex_AsCComplex() now tries to convert an
7776 object to complex using its __complex__() method before falling back
7777 to the __float__() method. Therefore, the functions in the cmath
7778 module now can operate on objects that define a __complex__()
7779 method.

Georg Brandl3ee81df2008-05-17 18:14:43 +00007781- Patch #1623563: allow __class__ assignment for classes with
7782 __slots__. The old and the new class are still required to have the
7783 same slot names.

7790 its type.

7796
Georg Brandl7b9c5552007-03-12 14:30:05 +00007797- Bug #1678647: write a newline after printing an exception in any
7798 case, even when converting the value to a string failed.
7799
Georg Brandl871f1bc2007-03-12 13:17:36 +00007800- The dir() function has been extended to call the __dir__() method on
Georg Brandl3ee81df2008-05-17 18:14:43 +00007801 its argument, if it exists. If not, it will work like before. This
7802 allows customizing the output of dir() in the presence of a
7803 __getattr__().

Collin Winter276887b2007-03-12 16:11:39 +00007805- Patch #922167: Python no longer segfaults when faced with infinitely
7806 self-recursive reload() calls (as reported by bug #742342).
7807
Georg Brandl3ee81df2008-05-17 18:14:43 +00007808- Patch #1675981: remove unreachable code from ``type.__new__()``

7812 parthensized forms. This means complex(repr(x)) now works instead of
7813 raising a ValueError.
Collin Wintere38051d2007-03-09 20:33:07 +00007814
Georg Brandlaa2321b2007-03-07 00:40:28 +00007815- Patch #703779: unset __file__ in __main__ after running a file. This
Georg Brandl3ee81df2008-05-17 18:14:43 +00007816 makes the filenames the warning module prints much more sensible
7817 when a PYTHONSTARTUP file is used.
Georg Brandlaa2321b2007-03-07 00:40:28 +00007818

Georg Brandl0fca97a2007-03-05 22:28:08 +00007830- Patch #1674228: when assigning a slice (old-style), check for the
7831 sq_ass_slice instead of the sq_slice slot.
7832
Georg Brandl3ee81df2008-05-17 18:14:43 +00007833- When printing an unraisable error, don't print exceptions. before
7834 the name. This duplicates the behavior whening normally printing
7835 exceptions.

Georg Brandl3ee81df2008-05-17 18:14:43 +00008368 AttributeError instead of an IOError when the server's response
8369 didn't contain a valid HTTP status line.
Georg Brandlf66b6032007-03-14 08:27:52 +00008370

Georg Brandl3ee81df2008-05-17 18:14:43 +00008386- Patch #1530482: add pydoc.render_doc() which returns the

8401
Georg Brandl92a6bae2007-03-13 17:43:32 +00008402- Patch #1603688: ConfigParser.SafeConfigParser now checks values that
Georg Brandl3ee81df2008-05-17 18:14:43 +00008403 are set for invalid interpolation sequences that would lead to
8404 errors on reading back those values.

8460 TestCase and TestSuite subclasses (not instances) are no longer
8461 accepted in TestSuite.addTest(). This should cause no
8462 incompatibility since it never made sense with ordinary subclasses
8463 -- the failure just occurred later, with a more cumbersome
8464 exception.

Gregory P. Smithbde4ae42008-01-17 08:35:49 +00008745 that the SMTP.starttls() caller no longer needs to call ehlo()

Gregory P. Smithec10a4a2007-11-05 02:32:26 +00008846- pybsddb.sf.net Bug #477182: Load the database flags at database open
Georg Brandl3ee81df2008-05-17 18:14:43 +00008847 time so that opening a database previously created with the DB_DUP
8848 or DB_DUPSORT flag set will keep the proper behavior on subsequent
8849 opens. Specifically: dictionary assignment to a DB object will
8850 replace all values for a given key when the database allows
8851 duplicate values. DB users should use DB.put(k, v) when they want
8852 to store duplicates; not DB[k] = v.

9217 of w# format code incorrectly truncated the length to an int, even
9218 when PY_SSIZE_T_CLEAN is set. The str.decode method used to return
9219 incorrect results with huge strings.

Georg Brandl3ee81df2008-05-17 18:14:43 +00009249- Added case insensitive comparison methods ``PyOS_stricmp(char*,
9250 char*)`` and ``PyOS_strnicmp(char*, char*, Py_ssize_t)``.
