167 int.__pow__. These overflow checks were causing int.__pow__ to produce

183 cleared by the garbage collector. This fixes a segfault when an instance
184 and its type get caught in a reference cycle, and the instance's
185 deallocator calls one of the methods on the type (e.g. when subclassing

247 Distutils-based packages with C extension modules may fail because
248 Apple has removed gcc-4.2, the version used to build python.org
249 64-bit/32-bit Pythons. If the user does not explicitly override
250 the default C compiler by setting the CC environment variable,
251 Distutils will now attempt to compile extension modules with clang
252 if gcc-4.2 is required but not found. Also as a convenience, if
253 the user does explicitly set CC, substitute its value as the default
254 compiler in the Distutils LDSHARED configuration variable for OS X.
255 (Note, the python.org 32-bit-only Pythons use gcc-4.0 and the 10.4u
256 SDK, neither of which are available in Xcode 4. This change does not
257 attempt to override settings to support their use with Xcode 4.)

Ned Deily87e82bb2011-06-28 19:52:59 -0700530- Issue #9516: On Mac OS X, change Distutils to no longer globally attempt to
531 check or set the MACOSX_DEPLOYMENT_TARGET environment variable for the
532 interpreter process. This could cause failures in non-Distutils subprocesses
533 and was unreliable since tests or user programs could modify the interpreter
534 environment after Distutils set it. Instead, have Distutils set the the
535 deployment target only in the environment of each build subprocess. It is
536 still possible to globally override the default by setting
537 MACOSX_DEPLOYMENT_TARGET before launching the interpreter; its value must be
538 greater or equal to the default value, the value with which the interpreter
539 was built.

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

1506 by Andrew Bennetts.

1515
Raymond Hettinger20397532010-09-12 02:11:45 +00001516- Issue #9825: removed __del__ from the definition of collections.OrderedDict.
1517 This prevents user-created self-referencing ordered dictionaries from
1518 becoming permanently uncollectable GC garbage. The downside is that
1519 removing __del__ means that the internal doubly-linked list has to wait for
1520 GC collection rather than freeing memory immediately when the refcnt drops
1521 to zero.
1522

1550 falling into recursion.
1551
R. David Murray7c4bf552010-08-25 01:45:57 +00001552- Issue #1194222: email.utils.parsedate now returns RFC2822 compliant four
1553 character years even if the message contains RFC822 two character years.
1554
Daniel Stutzbach91287322010-08-24 21:09:30 +00001555- Issue #8750: Fixed MutableSet's methods to correctly handle

1574
Raymond Hettingera54b2da2010-08-17 19:03:06 +00001575- Issue #9626: the view methods for collections.OrderedDict() were returning

1584 and a BadZipfile error is raised if it doesn't match (as used to be the
1585 case in Python 2.5 and earlier).
1586
Antoine Pitroucb4f47c2010-08-11 13:40:17 +00001587- Issue #9550: a BufferedReader could issue an additional read when the
1588 original read request had been satisfied, which could block indefinitely
1589 when the underlying raw IO channel was e.g. a socket. Report and original
1590 patch by Jason V. Miller.

1983 E.g.: '\xf1\x80AB'.decode('utf-8', 'replace') now returns u'\ufffdAB' and

1996 (2**53+1 == complex(2**53) == 2**53), breaking transivity of equality.

R. David Murray1a14d3d2010-04-12 16:35:19 +00002293- Issue #7585: difflib context and unified diffs now place a tab between
Georg Brandlfee0f442010-05-22 21:26:21 +00002294 filename and date, conforming to the 'standards' they were originally designed
2295 to follow. This improves compatibility with patch tools.

Mark Dickinsond2f3e3f2010-05-05 22:23:58 +00002341 (Optimization was unintentionally turned on in gcc --with-pydebug builds in
2342 2.7 beta1 as a result of the issue #1628484 fix, combined with autoconf's
2343 strange choice of default CFLAGS produced by AC_PROG_CC for gcc.)

2364-----------------
2365
Philip Jenveyaebbaeb2010-04-06 23:24:45 +00002366- Issue #7301: Add environment variable $PYTHONWARNINGS.
2367
Benjamin Peterson3a1dfa22010-04-06 21:50:00 +00002368- Issue #8329: Don't return the same lists from select.select when no fds are
2369 changed.
2370
Georg Brandlfee0f442010-05-22 21:26:21 +00002371- Issue #8259: ``1L << (2**31)`` no longer produces an 'outrageous shift error'
Mark Dickinson82791672010-04-06 16:47:55 +00002372 on 64-bit machines. The shift count for either left or right shift is
2373 permitted to be up to sys.maxsize.
2374
Benjamin Peterson4ceeeb02010-04-03 22:48:51 +00002375- Ensure that tokenization of identifiers is not affected by locale.
2376
Georg Brandlfee0f442010-05-22 21:26:21 +00002377- Issue #1222585: Added LDCXXSHARED for C++ support. Patch by Arfrever.
Tarek Ziadé00002952010-04-03 08:37:59 +00002378
Benjamin Peterson1c7c11e2010-04-03 01:28:57 +00002379- Raise a TypeError when trying to delete a T_STRING_INPLACE struct member.
2380
Georg Brandlfee0f442010-05-22 21:26:21 +00002381- Issue #7994: Issue a PendingDeprecationWarning if object.__format__ is called
2382 with a non-empty format string. This is an effort to future-proof user
2383 code. If a derived class does not currently implement __format__ but later
2384 adds its own __format__, it would most likely break user code that had
Antoine Pitrou01a196a2011-01-02 20:05:11 +00002385 supplied a format string. This will be changed to a DeprecationWarning in
Georg Brandlfee0f442010-05-22 21:26:21 +00002386 Python 3.3 and it will be an error in Python 3.4.
Eric Smithd44b2fc2010-04-02 12:30:56 +00002387
Antoine Pitroua57df2c2010-03-31 21:32:15 +00002388- Issue #8268: Old-style classes (not just instances) now support weak

Victor Stinner66644262010-03-10 22:30:19 +00002401- Issue #3137: Don't ignore errors at startup, especially a keyboard interrupt
Georg Brandlba83f822010-03-14 09:50:54 +00002402 (SIGINT). If an error occurs while importing the site module, the error is

2418
Georg Brandlfee0f442010-05-22 21:26:21 +00002419- Issue #8257: The Decimal construct now accepts a float instance directly,
2420 converting that float to a Decimal of equal value:
Mark Dickinson8a950712010-04-03 15:47:46 +00002421
2422 >>> Decimal(1.1)
2423 Decimal('1.100000000000000088817841970012523233890533447265625')
2424
Raymond Hettinger34c35b22010-04-03 10:22:00 +00002425- collections.Counter() now supports a subtract() method.
2426
Georg Brandlfee0f442010-05-22 21:26:21 +00002427- The functools module now has a total_ordering() class decorator to simplify
2428 the specification of rich comparisons.
Raymond Hettingera551f312010-04-04 18:34:45 +00002429
Georg Brandlfee0f442010-05-22 21:26:21 +00002430- The functools module also adds cmp_to_key() as a tool to transition old-style
2431 comparison functions to new-style key-functions.
Raymond Hettingera551f312010-04-04 18:34:45 +00002432
Georg Brandlfee0f442010-05-22 21:26:21 +00002433- Issue #8294: The Fraction constructor now accepts Decimal and float instances
2434 directly.

Georg Brandlfee0f442010-05-22 21:26:21 +00002436- Issue #7279: Comparisons involving a Decimal signaling NaN now signal
2437 InvalidOperation instead of returning False. (Comparisons involving a quiet
2438 NaN are unchanged.) Also, Decimal quiet NaNs are now hashable; Decimal
2439 signaling NaNs remain unhashable.
Mark Dickinsone096e822010-04-02 10:17:07 +00002440
Georg Brandlfee0f442010-05-22 21:26:21 +00002441- Issue #2531: Comparison operations between floats and Decimal instances now
2442 return a result based on the numeric values of the operands; previously they
2443 returned an arbitrary result based on the relative ordering of id(float) and
2444 id(Decimal).
Mark Dickinson99d80962010-04-02 08:53:22 +00002445
Barry Warsawf7f2d6f2010-03-31 21:07:16 +00002446- Issue #8233: When run as a script, py_compile.py optionally takes a single
Georg Brandlfee0f442010-05-22 21:26:21 +00002447 argument `-` which tells it to read files to compile from stdin. Each line is
2448 read on demand and the named file is compiled immediately. (Original patch by
2449 Piotr Ożarowski).

Florent Xicluna58b65662010-03-30 16:29:03 +00002454- Backwards incompatible change: Unicode codepoints line tabulation (0x0B) and
2455 form feed (0x0C) are now considered linebreaks, as specified in Unicode
Georg Brandlfee0f442010-05-22 21:26:21 +00002456 Standard Annex #14. See issue #7643. http://www.unicode.org/reports/tr14/
Florent Xicluna22b24382010-03-30 08:24:06 +00002457
Georg Brandlfee0f442010-05-22 21:26:21 +00002458- Comparisons using one of <, <=, >, >= between a complex instance and a
2459 Fractions instance now raise TypeError instead of returning True/False. This
2460 makes Fraction <=> complex comparisons consistent with int <=> complex, float
2461 <=> complex, and complex <=> complex comparisons.

Georg Brandlba83f822010-03-14 09:50:54 +00002529- Issue #7143: email: ``get_payload()`` used to strip any trailing newline from

Mark Dickinson4846a8e2010-04-03 14:05:10 +00002560- Issue #8300: When passing a non-integer argument to struct.pack with any
2561 integer format code, struct.pack first attempts to convert the non-integer

Georg Brandlba83f822010-03-14 09:50:54 +00002565- Issue #1530559: When passing a non-integer argument to struct.pack with *any*
2566 integer format code (one of 'bBhHiIlLqQ'), struct.pack attempts to use the
2567 argument's __int__ method to convert to an integer before packing. It also
Georg Brandlfee0f442010-05-22 21:26:21 +00002568 produces a DeprecationWarning in this case. (In Python 2.6, the behaviour was
2569 inconsistent: __int__ was used for some integer codes but not for others, and
2570 the set of integer codes for which it was used differed between native packing
2571 and standard packing.)

2824 could crash in many places because of the ``PyByteArray_AS_STRING()`` macro
2825 returning NULL. The macro now returns a statically allocated empty string
2826 instead.

Georg Brandlba83f822010-03-14 09:50:54 +00002872 specified, rather than fall through to AF_PACKET (in the ``socket`` module).

Antoine Pitrouf3fa0742010-01-31 22:26:04 +00002878- Issue #6939: Fix file I/O objects in the `io` module to keep the original
Georg Brandlba83f822010-03-14 09:50:54 +00002879 file position when calling `truncate()`. It would previously change the file
2880 position to the given argument, which goes against the tradition of
Antoine Pitrouf3fa0742010-01-31 22:26:04 +00002881 ftruncate() and other truncation APIs. Patch by Pascal Chambon.
2882
Georg Brandlba83f822010-03-14 09:50:54 +00002883- Issue #7610: Reworked implementation of the internal ``zipfile.ZipExtFile``
2884 class used to represent files stored inside an archive. The new
2885 implementation is significantly faster and can be wrapped in a
2886 ``io.BufferedReader`` object for more speedups. It also solves an issue
2887 where interleaved calls to ``read()`` and ``readline()`` give wrong results.
2888 Patch by Nir Aides.

Georg Brandlba83f822010-03-14 09:50:54 +00002898- Issue #7748: Since unicode values are supported for some metadata options in
2899 Distutils, the DistributionMetadata get_* methods will now return an utf-8
2900 encoded string for them. This ensures that the upload and register commands
2901 send the correct values to PyPI without any error.

Georg Brandlba83f822010-03-14 09:50:54 +00003172- Issue #7117: ``repr(x)`` for a float x returns a result based on the shortest
3173 decimal string that's guaranteed to round back to x under correct rounding
3174 (with round-half-to-even rounding mode). Previously it gave a string based on
3175 rounding x to 17 decimal digits. repr(x) for a complex number behaves
3176 similarly. On platforms where the correctly-rounded strtod and dtoa code is
3177 not supported (see below), repr is unchanged.
Mark Dickinsonb678de82009-11-19 18:41:49 +00003178
Georg Brandlba83f822010-03-14 09:50:54 +00003179- Issue #7117: On almost all platforms: float-to-string and string-to-float
3180 conversions within Python are now correctly rounded. Places these conversions
3181 occur include: str for floats and complex numbers; the float and complex
3182 constructors; old-style and new-style numeric formatting; serialization and
3183 deserialization of floats and complex numbers using marshal, pickle and json;
3184 parsing of float and imaginary literals in Python code; Decimal-to-float
3185 conversion.
Mark Dickinsonb678de82009-11-19 18:41:49 +00003186
Georg Brandlba83f822010-03-14 09:50:54 +00003187 The conversions use a Python-adapted version of David Gay's well-known dtoa.c,
3188 providing correctly-rounded strtod and dtoa C functions. This code is
3189 supported on Windows, and on Unix-like platforms using gcc, icc or suncc as
3190 the C compiler. There may be a small number of platforms on which correct
3191 operation of this code cannot be guaranteed, so the code is not used: notably,
3192 this applies to platforms where the C double format is not IEEE 754 binary64,
3193 and to platforms on x86 hardware where the x87 FPU is set to 64-bit precision
3194 and Python's configure script is unable to determine how to change the FPU
3195 precision. On these platforms conversions use the platform strtod and dtoa,
3196 as before.

Georg Brandlba83f822010-03-14 09:50:54 +00003198- Issue #7117: Backport round implementation from Python 3.x. ``round()`` now
3199 uses the correctly-rounded string <-> float conversions described above (when
3200 available), and so produces correctly rounded results that will display nicely
3201 under the float repr. There are two related small changes: (1) round now
3202 accepts any class with an ``__index__()`` method for its second argument (but
3203 no longer accepts floats for the second argument), and (2) an excessively
3204 large second integer argument (e.g., ``round(1.234, 10**100)``) no longer
3205 raises an exception.

Georg Brandlba83f822010-03-14 09:50:54 +00003352- Issue #5920: For ``float.__format__()``, change the behavior with the empty
3353 presentation type (that is, not one of 'e', 'f', 'g', or 'n') to be like 'g'
3354 but with at least one decimal point and with a default precision
3355 of 12. Previously, the behavior the same but with a default precision of 6.
3356 This more closely matches ``str()``, and reduces surprises when adding

Georg Brandlba83f822010-03-14 09:50:54 +00003498- Issue #1180193: When importing a module from a .pyc (or .pyo) file with an
3499 existing .py counterpart, override the co_filename attributes of all code
3500 objects if the original filename is obsolete (which can happen if the file has

3555
Georg Brandlba83f822010-03-14 09:50:54 +00003556- Issue #4233: Changed semantic of ``_fileio.FileIO``'s ``close()`` method on
3557 file objects with closefd=False. The file descriptor is still kept open but
3558 the file object behaves like a closed file. The ``FileIO`` object also got a
3559 new readonly attribute ``closefd``.

3578
Benjamin Peterson399b1fe2008-10-25 02:53:28 +00003579- Using ``nonlocal`` as a variable name will now raise a Py3k SyntaxWarning

Georg Brandlba83f822010-03-14 09:50:54 +00003582- On windows, ``os.chdir()`` given unicode was not working if
3583 GetCurrentDirectoryW returned a path longer than MAX_PATH. (But It's doubtful
3584 this code path is really executed because I cannot move to such directory on
3585 win2k)

Georg Brandlba83f822010-03-14 09:50:54 +00003587- Issue #4069: When ``set.remove(element)`` is used with a set element, the
3588 element is temporarily replaced with an equivalent frozenset. But the
3589 eventual KeyError would always report the empty ``frozenset()`` as the missing
3590 key. Now it correctly refers to the initial element.

Walter Dörwalded960ac2009-05-03 22:36:33 +00003610- Issue #5108: Handle %s like %S and %R in PyUnicode_FromFormatV(): Call
3611 PyUnicode_DecodeUTF8() once, remember the result and output it in a second
3612 step. This avoids problems with counting UTF-8 bytes that ignores the effect
3613 of using the replace error handler in PyUnicode_DecodeUTF8().
3614
Walter Dörwald726ba8e2009-05-06 14:32:35 +00003615- Issue #3739: The unicode-internal encoder now reports the number of characters

3617
Georg Brandlba83f822010-03-14 09:50:54 +00003618- Issue #2422: When compiled with the ``--with-valgrind`` option, the pymalloc
3619 allocator will be automatically disabled when running under Valgrind. This
3620 gives improved memory leak detection when running under Valgrind, while taking
3621 advantage of pymalloc at other times.

Georg Brandlba83f822010-03-14 09:50:54 +00004828- Issue #7431: Use TESTFN in test_linecache instead of trying to create a file
4829 in the Lib/test directory, which might be read-only for the user running the
4830 tests.
R. David Murray820b0ea2009-12-03 23:57:59 +00004831
Georg Brandlba83f822010-03-14 09:50:54 +00004832- Issue #7324: Add a sanity check to regrtest argument parsing to catch the case
4833 of an option with no handler.

Georg Brandlba83f822010-03-14 09:50:54 +00004844 leak-chasing test runs give sensible results. The previous method of reaping
4845 threads could return successfully while some Thread objects were still
4846 referenced. This also introduces a new private function: ``thread._count()``.
Antoine Pitrou59c44f32009-10-30 17:07:08 +00004847
Georg Brandlba83f822010-03-14 09:50:54 +00004848- Issue #7151: Fixed regrtest -j so that output to stderr from a test no longer
4849 runs the risk of causing the worker thread to fail.

Antoine Pitrou58d2f262009-10-10 20:52:11 +00004851- Issue #7055: test___all__ now greedily detects all modules which have an
4852 __all__ attribute, rather than using a hardcoded and incomplete list.
4853
R. David Murray14dcd432009-10-14 13:58:07 +00004854- Issue #7058: Added save/restore for things like sys.argv and cwd to
4855 runtest_inner in regrtest, with warnings if the called test modifies them,
4856 and a new section in the summary report at the end.

Guilherme Polo7f146ab2009-06-21 17:22:50 +00004863- Issue #5450: Moved tests involving loading tk from Lib/test/test_tcl to
4864 Lib/lib-tk/test/test_tkinter/test_loadtk. With this, these tests demonstrate
Georg Brandlba83f822010-03-14 09:50:54 +00004865 the same behaviour as test_ttkguionly (and now also test_tk) which is to skip
4866 the tests if DISPLAY is defined but can't be used.

Georg Brandlba83f822010-03-14 09:50:54 +00004871- Issue #5354: New test support function import_fresh_module() makes it easy to
4872 import both normal and optimised versions of modules. test_heapq and
4873 test_warnings have been adjusted to use it, tests for other modules with both
4874 C and Python implementations in the stdlib can be adjusted to use it over
4875 time.

Georg Brandlba83f822010-03-14 09:50:54 +00004883- regrtest no longer treats ImportError as equivalent to SkipTest. Imports that
4884 should cause a test to be skipped are now done using import_module from test
4885 support, which does the conversion.

4987
Amaury Forgeot d'Arc05e34492008-09-10 22:04:45 +00004988- Issue #3743: In a few places, PY_FORMAT_SIZE_T was incorrectly used with
4989 PyString_FromFormat or PyErr_Format to display size_t values. The macro
4990 PY_FORMAT_SIZE_T is designed to select the correct format for the OS
4991 ``printf`` function, whereas PyString_FromFormat has an independent
4992 implementation and uses "%zd" on all platforms for size_t values.
4993 This makes a difference on win64, where ``printf`` needs "%Id" to display
4994 64bit values.

Benjamin Peterson97179b02008-09-09 20:55:01 +00004996- Issue #3634: _weakref.ref(Exception).__init__() gave invalid return value on

5000 object; previously an int would be returned for small values. the __long__
5001 method is allowed to return either an int or a long, but the behaviour of
5002 float objects should not change to respect backward compatibility.

Antoine Pitroud4ae97b2008-08-29 18:39:48 +00005011 was correctly parsed but parsing of subsequent arguments failed.
5012
Vinay Sajip35e3b032008-09-01 14:33:59 +00005013- Issue #2534: speed up isinstance() and issubclass() by 50-70%, so as to
Antoine Pitrou0668c622008-08-26 22:42:08 +00005014 match Python 2.5 speed despite the __instancecheck__ / __subclasscheck__
5015 mechanism. In the process, fix a bug where isinstance() and issubclass(),
5016 when given a tuple of classes as second argument, were looking up
5017 __instancecheck__ / __subclasscheck__ on the tuple rather than on each
5018 type object.

5111-----------------
5112
Jesse Noller438195f2009-01-18 21:04:36 +00005113- Issue #4301: Patch the logging module to add processName support, remove
5114 _check_logger_class from multiprocessing.
5115
Amaury Forgeot d'Arc293924b2008-09-02 23:19:56 +00005116- Issue #2975: When compiling several extension modules with Visual Studio 2008
5117 from the same python interpreter, some environment variables would grow
5118 without limit.
5119
Benjamin Peterson37346b22008-08-23 20:27:43 +00005120- Issue #3643: Added a few more checks to _testcapi to prevent segfaults by
5121 exploitation of poor argument checking.
5122
Gerhard Häringef2276b2008-09-12 13:54:06 +00005123- sqlite3: Changed docstring of iterdump() to mark method as "Non-standard".
5124
Gerhard Häring6e1afcf2008-09-12 18:58:57 +00005125- Issue #3103: Reduced globals symbols used by sqlite3 module and made sure all
5126 remaining ones have "pysqlite_" prefix.
5127
Gerhard Häringe6872eb2008-09-12 22:33:22 +00005128- Issue #3846: Release the GIL during sqlite3_prepare calls. This improves

Nick Coghland2e09382008-09-11 12:11:06 +00005135- Issue #3781: Add test.test_support.check_warnings() as a convenience
5136 wrapper for warnings.catch_warnings() that makes it easier to check
5137 that expected warning messages are being reported.
5138
Amaury Forgeot d'Arcfeb8cad2008-09-06 20:53:51 +00005139- Issue #3796: Some tests functions were not enabled in test_float.

Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00005157What's New in Python 2.6 beta 3?
5158================================
5159
Barry Warsaw07a4a382008-08-21 01:15:08 +00005160*Release date: 20-Aug-2008*
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00005161
5162Core and Builtins
5163-----------------
5164
Guido van Rossumf8402962008-08-20 15:01:50 +00005165- Issue #1878: Remove Py_TPFLAGS_HAVE_VERSION_TAG from
5166 Py_TPFLAGS_DEFAULT when not building the core. This means 3rd party
5167 extensions do not automatically benefit from the class attribute
5168 cache; they will have to explicitly add Py_TPFLAGS_HAVE_VERSION_TAG
5169 to their tp_flags field if they care. This is a backwards
5170 compatibility feature; in 3.0, all types will use the cache by
5171 default.
5172
Benjamin Petersonf647dc12008-08-20 01:27:30 +00005173- Keyword arguments can now follow starred arguments. (``f(a, *args,
5174 keyword=23)`` is now valid syntax.)
5175
Thomas Heller0ad5ae02008-08-19 19:25:04 +00005176- ctypes function pointers that are COM methods have a boolean True
5177 value again.
5178
Martin v. Löwisf91d46a2008-08-12 14:49:50 +00005179- Issue #3139: Make buffer-interface thread-safe wrt. PyArg_ParseTuple,
5180 by denying s# to parse objects that have a releasebuffer procedure,
5181 and introducing s*.
5182
Georg Brandl1e13ea92008-08-11 09:07:59 +00005183- Issue #3537: Fix an assertion failure when an empty but presized dict
5184 object was stored in the freelist.
5185
Mark Dickinsonb6467572008-08-04 21:30:09 +00005186- Issue #1481296: Make long(float('nan')) and int(float('nan')) raise
5187 ValueError consistently across platforms.
5188
Amaury Forgeot d'Arc39fd6722008-07-31 21:28:03 +00005189- Issue #3479: On platforms where sizeof(int) is smaller than sizeof(long)
5190 (64bit Unix, for example), unichr() would truncate its argument and return
5191 u'\x00' for unichr(2**32). Now it properly raises an OverflowError.
5192
Neal Norwitze7d8be82008-07-31 17:17:14 +00005193- Apply security patches from Apple.
5194
Amaury Forgeot d'Arc246daed2008-07-31 00:42:16 +00005195- Issue #2542: Now that issubclass() may call arbitrary code, ensure that
5196 PyErr_ExceptionMatches returns 0 when an exception occurs there.
5197
Antoine Pitrou92f82162008-07-25 22:22:08 +00005198- Issue #1819: function calls with several named parameters are now on
5199 average 35% faster (as measured by pybench).
5200
Amaury Forgeot d'Arce4921fe2008-07-21 22:00:38 +00005201- Issue #2378: An unexpected UnboundLocalError or NameError could appear when
5202 the python debugger steps into a class statement: the free variables (local
5203 variables defined in an outer scope) would be deleted from the outer scope.
5204
Gregory P. Smith0470bab2008-07-22 04:46:32 +00005205- Issue #2620: Overflow checking when allocating or reallocating memory
5206 was not always being done properly in some python types and extension
5207 modules. PyMem_MALLOC, PyMem_REALLOC, PyMem_NEW and PyMem_RESIZE have
5208 all been updated to perform better checks and places in the code that
5209 would previously leak memory on the error path when such an allocation
5210 failed have been fixed.
5211
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00005212Library
5213-------
5214
Hirokazu Yamamoto838c79f2008-08-20 13:14:07 +00005215- Issue #3612: Added some missing basic types in ctypes.wintypes.
5216
Benjamin Petersone977ad42008-08-20 01:42:01 +00005217- The methods ``is_in_tuple()``, ``is_vararg()``, and ``is_keywordarg()`` of
5218 symtable.Symbol have been deprecated for removal in 3.0 and the next release.
5219
Amaury Forgeot d'Arc351ffb82008-08-18 19:23:47 +00005220- Issue #2234: distutils failed for some versions of the cygwin compiler. The
5221 version reported by these tools does not necessarily follow the python
5222 version numbering scheme, so the module is less strict when parsing it.
5223
Nick Coghlanf70385a2008-08-18 12:42:46 +00005224- Issue #2235: Added Py3k warnings for types which will become unhashable
5225 under the stricter __hash__ inheritance rules in 3.0. Several types
5226 which did not meet the rules for hash invariants and were already
5227 unhashable in 3.0 have now been explicitly flagged as unhashable in
5228 2.6 as well (collections.Mapping, collections.Set, unittest.TestSuite,
5229 xml.dom.minidom.NamedNodeMap, numbers.Number, UserList.UserList)
5230
Brett Cannon88f801d2008-08-18 00:46:22 +00005231- Update __all__ for cookielib, csv, os, urllib2, and weakref to include things
5232 imported into the module but exposed as part of the module's API.
5233
Brett Cannon7b96f072008-08-18 00:41:11 +00005234- Remove an unneeded import of abc.ABCMeta from 'inspect'.
5235
Brett Cannon46225e72008-08-18 00:36:52 +00005236- Remove unneeded imports of 'sys' and 'warnings' from 'io'.
5237
Brett Cannon25c9d6a2008-08-17 22:10:11 +00005238- Remove unneeded imports of 'warnings' from shelve, filecmp, and dummy_thread.
5239
Hirokazu Yamamoto41a81eb2008-08-17 13:10:46 +00005240- Issue #3575: Incremental decoder's decode function now takes bytearray
5241 by using 's*' instead of 't#'.
5242
Mark Dickinson3e4caeb2009-02-21 20:27:01 +00005243- Issue #2222: Fixed reference leak when occurred os.rename()
Hirokazu Yamamoto7f30a682008-08-17 09:46:56 +00005244 fails unicode conversion on 2nd parameter. (windows only)
5245
Georg Brandl222e2082010-08-01 22:27:39 +00005246- Issue #2464: urllib2 now supports a malformation in the URL received
Facundo Batista94f243a2008-08-17 03:38:39 +00005247 in a redirect.
5248
Brett Cannonabe423e2008-08-16 21:47:07 +00005249- Silence the DeprecationWarning raised when importing mimetools in
Brett Cannon721b1452008-08-16 22:00:27 +00005250 BaseHTTPServer, cgi (and rfc822), httplib.
Brett Cannonabe423e2008-08-16 21:47:07 +00005251
Facundo Batistaeb90b782008-08-16 14:44:07 +00005252- Issue #2776: fixed small issue when handling an URL with double slash
5253 after a 302 response in the case of not going through a proxy.
5254
Antoine Pitroub90a8be2008-08-15 21:03:21 +00005255- Issue #2676: in the email package, content-type parsing was hanging on
5256 pathological input because of quadratic or exponential behaviour of a
5257 regular expression.
5258
Antoine Pitrou11ec65d2008-08-14 21:04:30 +00005259- Issue #3476: binary buffered reading through the new "io" library is now
5260 thread-safe.
5261
Brett Cannonbf3157b2008-08-14 05:00:03 +00005262- Silence the DeprecationWarning of rfc822 when it is imported by mimetools
5263 since mimetools itself is deprecated. Because modules are cached, all
5264 subsequent imports of rfc822 will not raise a visible DeprecationWarning.
5265
Antoine Pitrou9fcd4b32008-08-11 17:21:36 +00005266- Issue #3134: shutil referenced undefined WindowsError symbol.
5267
Robert Schuppenies14646332008-08-10 11:01:53 +00005268- Issue #1342811: Fix leak in Tkinter.Menu.delete. Commands associated to
5269 menu entries were not deleted.
5270
Brett Cannon83e81842008-08-09 23:30:55 +00005271- Copied the implementation of reduce() to _functools.reduce() to have a
5272 version that did not raise a DeprecationWarning under -3.
5273
Antoine Pitrou76b8bee2008-08-09 17:27:23 +00005274- Issue #3205: When iterating over a BZ2File fails allocating memory, raise
5275 a MemoryError rather than silently stop the iteration.
5276
Guido van Rossum59ce9012008-08-09 14:55:34 +00005277- Issue #3487: sre "bytecode" validator. Passing invalid "re-bytecode"
5278 to _sre.compile() will now be rejected. This should not affect anybody
5279 since the re.compile() function never generates invalid re-bytecode.
5280
Skip Montanaroa032bf42008-08-08 22:52:51 +00005281- Issue #3436: Make csv.DictReader's fieldnames attribute a property so that
5282 upon first access it can be automatically initialized from the csv file if
5283 it wasn't initialized during instantiation.
5284
Brett Cannon3aa2a492008-08-06 22:28:09 +00005285- Issue #2338: Create imp.reload() to help with transitioning to Python 3.0 as
5286 the reload() built-in has been removed.
5287
Brett Cannon7e30b672008-08-04 21:52:25 +00005288- Changed code in the following modules/packages to remove warnings raised
Brett Cannonc1b76e42008-08-09 23:06:16 +00005289 while running under the ``-3`` flag: aifc, asynchat, asyncore, bdb, bsddb,
Brett Cannon047e4a92008-08-17 04:16:04 +00005290 ConfigParser, cookielib, csv, difflib, distutils, DocXMLRPCServer, email,
5291 filecmp, fileinput, inspect, logging, modulefinder, pdb, pickle, profile,
5292 pstats, pydoc, re, rlcompleter, SimpleXMLRPCServer, shelve, socket,
5293 subprocess, sqlite3, tarfile, Tkinter, test.test_support, textwrap,
5294 threading, tokenize, traceback, urlparse, wsgiref, xml, xmlrpclib.
Brett Cannon7e30b672008-08-04 21:52:25 +00005295
Lars Gustäbel727bd0b2008-08-02 11:26:39 +00005296- Issue #3039: Fix tarfile.TarFileCompat.writestr() which always
5297 raised an AttributeError.
5298
Benjamin Peterson01a24322008-07-28 23:35:27 +00005299- Issue #2523: Fix quadratic behaviour when read()ing a binary file without
Antoine Pitroude781a42008-08-09 12:43:23 +00005300 asking for a specific length. This problem only affected files opened
5301 using the new "io" module, not the built-in open() function.
Benjamin Peterson01a24322008-07-28 23:35:27 +00005302
Mark Dickinsonfe84cce2008-07-27 06:39:07 +00005303- Issue #3449: Update decimal module to use most recent specification
5304 (v. 1.68) and tests (v. 2.58) from IBM.
5305
Georg Brandl222e2082010-08-01 22:27:39 +00005306- Issue #3437: Bug fix in robotparser parsing of Allow: lines.

5310
Georg Brandlf9efabb2008-07-23 15:16:45 +00005311- Deprecate the "ast" parser function aliases.
5312
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00005313- Issue #3120: On 64-bit Windows the subprocess module was truncating handles.
5314
5315- Issue #3303: Fix a crash in locale.strcoll() when calling it with
5316 invalid arguments.
5317
5318- Issue #3302: Fix several crashes when calling locale's gettext functions
5319 with None arguments.
5320
5321- Issue #3389: Allow resolving dotted names for handlers in logging
5322 configuration files.
5323

5325
Antoine Pitrou5fdfa3e2008-07-25 19:42:26 +00005326- Issue #3394: zipfile.writestr sets external attributes when passed a
5327 file name rather than a ZipInfo instance, so files are extracted with
5328 mode 0600 rather than 000 under Unix.
5329
Gregory P. Smitha36f8fe2008-08-04 00:13:29 +00005330- Issue #1857: subprocess.Popen.poll gained an additional _deadstate keyword
5331 argument in python 2.5, this broke code that subclassed Popen to include its
5332 own poll method. Fixed my moving _deadstate to an _internal_poll method.

Nick Coghlan2a0c2b12008-08-04 12:47:17 +00005339Documentation
5340-------------
5341
Nick Coghlan6e8fef02008-08-18 13:14:22 +00005342- Issue #2235: the C API function PyObject_HashNotImplemented and its
5343 interaction with the tp_hash slot (added in 2.6b2) are now documented
5344
Nick Coghlan2a0c2b12008-08-04 12:47:17 +00005345- Issue #643841: The language reference now provides more detailed
5346 coverage of the lookup process for special methods. The disclaimers
5347 regarding lack of coverage of new-style classes have also been
5348 removed, since the coverage is now fairly reasonable.

Raymond Hettingere3ae6552008-06-20 04:18:15 +00005351What's New in Python 2.6 beta 2?
5352================================
5353
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00005354*Release date: 17-Jul-2008*
5355
Raymond Hettingere3ae6552008-06-20 04:18:15 +00005356Core and Builtins
5357-----------------
5358
Georg Brandl3e483f62008-07-16 22:57:41 +00005359- Issue #3156: Fix inconsistent behavior of the bytearray type: all
5360 its methods now allow for items objects that can be converted to
5361 an integer using operator.index().
5362
Mark Dickinson64b7e502008-07-16 09:40:03 +00005363- Issue #3360: Fix incorrect parsing of '020000000000.0', which
5364 produced a ValueError instead of giving the correct float.
5365
Eric Smitha5fa5a22008-07-16 00:11:49 +00005366- Issue #3083: Add alternate (#) formatting for bin, oct, hex output
5367 for str.format(). This adds the prefix 0b, 0o, or 0x, respectively.
5368
Mark Dickinson7103aa42008-07-15 19:08:33 +00005369- Issue #3008: the float type has a new instance method 'float.hex'
5370 and a new class method 'float.fromhex' to convert floating-point
5371 numbers to and from hexadecimal strings, respectively.
5372
Nick Coghlan6d6bd442008-07-15 15:40:22 +00005373- Issue #2235: __hash__ is once again inherited by default. To allow
5374 collections.Hashable to remain meaningful in the presence of the
5375 default hash implementation (object.__hash__), it is now possible
5376 to explicit block inheritance of hash by setting __hash__=None at
5377 the Python level, or tp_hash=PyObject_HashNotImplemented at the C
5378 level.
5379
Nick Coghlanb028f502008-07-13 14:52:36 +00005380- Issue #3221: Issue a RuntimeWarning instead of raising SystemError if
5381 the parent module cannot be found while performing an absolute import.
5382 This means that an incorrectly defined __package__ attribute will
5383 now only prevent relative imports in that module rather than causing
5384 all imports from that module to fail.
5385
Nick Coghlan14ff9942008-07-08 14:21:42 +00005386- Issue #2517: Allow unicode messages in Exceptions again by correctly
5387 bypassing the instance dictionary when looking up __unicode__ on
5388 new-style classes.
5389
Amaury Forgeot d'Arcbdd941f2008-07-01 20:38:04 +00005390- Issue #3242: Fix a crash inside the print statement, if sys.stdout is
5391 set to a custom object whose write() method happens to install
5392 another file in sys.stdout.
5393
Amaury Forgeot d'Arc1f40c8a2008-06-30 22:42:40 +00005394- Issue #3088: Corrected a race condition in classes derived from
5395 threading.local: the first member set by a thread could be saved in
5396 another thread's dictionary.
5397
Mark Dickinson1ec2fcd2008-06-20 14:53:43 +00005398- Issue #3004: Minor change to slice.indices(): the start and stop
5399 arguments are now treated identically, making the behaviour easier
5400 to describe and understand. For example, slice(None, -10,
5401 1).indices(9) now returns (0, 0, 1) instead of (0, -1, 1), and
5402 slice(None, 10, -1).indices(10) returns (9, 9, -1) instead of (9,

Georg Brandl5cc774e2008-06-11 20:28:06 +00005857 PPC64 and x86_64 support in one binary).
Ronald Oussoren5640ce22008-06-05 12:58:24 +00005858
5859 This is controlled by the configure argument ``--with-universal-archs``:
5860

5862
5863 - ``--with-universal-archs=32-bit``: install 2-way universal, 32-bit (the default)
5864
5865 - ``--with-universal-archs=64-bit``: install 2-way universal, 64-bit
5866

Georg Brandl3ee81df2008-05-17 18:14:43 +00005919- Issue #1631171: Re-implement the 'warnings' module in C (the
5920 original Python code has been kept as backup). This will allow for
5921 using the 'warning's machinery in such places as the parser where
5922 use of pure Python code is not possible. Both the ``showarning()``
5923 and ``formatwarning()`` gain an optional 'line' argument which is
5924 not called by default for backwards-compatibility reasons. Setting
5925 ``warnings.showwarning()`` to an implementation that lacks support
5926 for the ``line`` argument will raise a DeprecationWarning.

Gregory P. Smithd59fefb2008-04-22 08:11:33 +00005951- The getpass module has been improved on Unix. It now uses /dev/tty

Georg Brandl3ee81df2008-05-17 18:14:43 +00005989- Issue #2550: The approach used by client/server code for obtaining
5990 ports to listen on in network-oriented tests has been refined in an
5991 effort to facilitate running multiple instances of the entire
5992 regression test suite in parallel without issue.
5993 test_support.bind_port() has been fixed such that it will always
5994 return a unique port -- which wasn't always the case with the
5995 previous implementation, especially if socket options had been set
5996 that affected address reuse (i.e. SO_REUSEADDR, SO_REUSEPORT). The
5997 new implementation of bind_port() will actually raise an exception
5998 if it is passed an AF_INET/SOCK_STREAM socket with either the
5999 SO_REUSEADDR or SO_REUSEPORT socket option set. Furthermore, if
6000 available, bind_port() will set the SO_EXCLUSIVEADDRUSE option on
6001 the socket it's been passed. This currently only applies to
6002 Windows. This option prevents any other sockets from binding to the
6003 host/port we've bound to, thus removing the possibility of the
6004 'non-deterministic' behaviour, as Microsoft puts it, that occurs
6005 when a second SOCK_STREAM socket binds and accepts to a host/port
6006 that's already been bound by another socket. The optional preferred
6007 port parameter to bind_port() has been removed. Under no
6008 circumstances should tests be hard coding ports!
6009
6010 test_support.find_unused_port() has also been introduced, which will
6011 pass a temporary socket object to bind_port() in order to obtain an
6012 unused port. The temporary socket object is then closed and
6013 deleted, and the port is returned. This method should only be used
6014 for obtaining an unused port in order to pass to an external program
6015 (i.e. the -accept [port] argument to openssl's s_server mode) or as
6016 a parameter to a server-oriented class that doesn't give you direct
6017 access to the underlying socket used.
6018
6019 Finally, test_support.HOST has been introduced, which should be used
6020 for the host argument of any relevant socket calls (i.e. bind and
6021 connect).
Trent Nelsone41b0062008-04-08 23:47:30 +00006022
6023 The following tests were updated to following the new conventions:
Georg Brandl3ee81df2008-05-17 18:14:43 +00006024 test_socket, test_smtplib, test_asyncore, test_ssl, test_httplib,
Trent Nelsone41b0062008-04-08 23:47:30 +00006025 test_poplib, test_ftplib, test_telnetlib, test_socketserver,
6026 test_asynchat and test_socket_ssl.
6027
Georg Brandl3ee81df2008-05-17 18:14:43 +00006028 It is now possible for multiple instances of the regression test
6029 suite to run in parallel without issue.

Eric Smitha73fbe72008-02-23 03:09:44 +00006308- Added the future_builtins module, which contains hex() and oct().
6309 These are the PEP 3127 version of these functions, designed to be
6310 compatible with the hex() and oct() builtins from Python 3.0. They
6311 differ slightly in their output formats from the existing, unchanged
6312 Python 2.6 builtins. The expected usage of the future_builtins
6313 module is:
6314 from future_builtins import hex, oct
6315
Eric Smith7ef40bf2008-02-20 23:34:22 +00006316- Issue #1600: Modifed PyOS_ascii_formatd to use at most 2 digit
6317 exponents for exponents with absolute value < 100. Follows C99
6318 standard. This is a change on Windows, which would use 3 digits.
6319 Also, added 'n' to the formats that PyOS_ascii_formatd understands,
6320 so that any alterations it does to the resulting string will be
6321 available in stringlib/formatter.h (for float.__format__).
6322
Eric Smith5a3c1352008-02-19 13:21:56 +00006323- Implemented PEP 3101, Advanced String Formatting. This adds a new
6324 builtin format(); a format() method for str and unicode; a
6325 __format__() method to object, str, unicode, int, long, float, and
6326 datetime; the class string.Formatter; and the C API
6327 PyObject_Format().
6328
Georg Brandl3ee81df2008-05-17 18:14:43 +00006329- Fixed several potential crashes, all caused by specially crafted
6330 __del__ methods exploiting objects in temporarily inconsistent
6331 state.
Amaury Forgeot d'Arc632fad32008-02-16 20:55:24 +00006332
Vinay Sajipb7edfc42008-04-02 21:10:23 +00006333- Issue #2115: Important speedup in setting __slot__ attributes. Also
Georg Brandl3ee81df2008-05-17 18:14:43 +00006334 prevent a possible crash: an Abstract Base Class would try to access
6335 a slot on a registered virtual subclass.
Amaury Forgeot d'Arc60d6c7f2008-02-15 21:22:45 +00006336

Georg Brandl3ee81df2008-05-17 18:14:43 +00006340- Clear all free lists during a gc.collect() of the highest generation
6341 in order to allow pymalloc to free more arenas. Python may give back
6342 memory to the OS earlier.
Christian Heimes3b718a72008-02-14 12:47:33 +00006343
Georg Brandl3ee81df2008-05-17 18:14:43 +00006344- Issue #2045: Fix an infinite recursion triggered when printing a
6345 subclass of collections.defaultdict, if its default_factory is set
6346 to a bound method.
Amaury Forgeot d'Arcb01aa432008-02-08 00:56:02 +00006347
Christian Heimesf75dbef2008-02-08 00:11:31 +00006348- Fixed a minor memory leak in dictobject.c. The content of the free
6349 list was not freed on interpreter shutdown.
6350
Georg Brandl21e99f42010-03-07 15:23:59 +00006351- Limit free list of method and built-in function objects to 256
Georg Brandl3ee81df2008-05-17 18:14:43 +00006352 entries each.
Christian Heimes6075a822008-02-06 12:44:34 +00006353
Georg Brandl3ee81df2008-05-17 18:14:43 +00006354- Patch #1953: Added ``sys._compact_freelists()`` and the C API
6355 functions ``PyInt_CompactFreeList`` and ``PyFloat_CompactFreeList``
Christian Heimes422051a2008-02-04 18:00:12 +00006356 to compact the internal free lists of pre-allocted ints and floats.
6357
Georg Brandl3ee81df2008-05-17 18:14:43 +00006358- Issue #1983: Fixed return type of fork(), fork1() and forkpty()
6359 calls. Python expected the return type int but the fork familie
6360 returns pi_t.
Christian Heimes951cc0f2008-01-31 23:08:23 +00006361
Georg Brandl3ee81df2008-05-17 18:14:43 +00006362- Issue #1678380: Fix a bug that identifies 0j and -0j when they
6363 appear in the same code unit.
Mark Dickinson105be772008-01-31 22:17:37 +00006364
Georg Brandl3ee81df2008-05-17 18:14:43 +00006365- Issue #2025: Add tuple.count() and tuple.index() methods to comply
6366 with the collections.Sequence API.

6372 the internal lookup cache for ref leak tests.
Christian Heimes908caac2008-01-27 23:34:59 +00006373
Georg Brandl3ee81df2008-05-17 18:14:43 +00006374- Patch #1473257: generator objects gain a gi_code attribute. This is
6375 the same object as the func_code attribute of the function that
6376 produced the generator.
Georg Brandl0cdf9a32008-01-26 14:14:20 +00006377
Georg Brandl3ee81df2008-05-17 18:14:43 +00006378- Issue #1920: "while 0" statements were completely removed by the
6379 compiler, even in the presence of an "else" clause, which is
6380 supposed to be run when the condition is false. Now the compiler
6381 correctly emits bytecode for the "else" suite.
Amaury Forgeot d'Arc31eaafe2008-01-24 22:59:25 +00006382
Guido van Rossumeead05f2008-01-24 18:21:02 +00006383- A few crashers fixed: weakref_in_del.py (issue #1377858);
6384 loosing_dict_ref.py (issue #1303614, test67.py);
6385 borrowed_ref_[34].py (not in tracker).
6386
Vinay Sajipd7cf32e2008-01-24 12:43:33 +00006387- Issue #1069410: The "can't load dll" message box on Windows is
Christian Heimesb2302ba2008-01-23 17:15:06 +00006388 suppressed while an extension is loaded by calling SetErrorMode in
6389 dynload_win.c. The error is still reported properly.
6390
Georg Brandl3ee81df2008-05-17 18:14:43 +00006391- Issue #1915: Python compiles with --enable-unicode=no again. However
Christian Heimes082c9b02008-01-23 14:20:50 +00006392 several extension methods and modules do not work without unicode
6393 support.
6394
Georg Brandl26543b12008-01-21 18:36:51 +00006395- Issue #1882: when compiling code from a string, encoding cookies in the
6396 second line of code were not always recognized correctly.
6397
Georg Brandl14404b62008-01-19 19:27:05 +00006398- Issue #1679: "0x" was taken as a valid integer literal.
6399
Georg Brandl6caad7d2008-01-26 14:19:22 +00006400- Issue #1865: ``bytes`` as an alias for ``str`` and b"" as an alias "" were
Christian Heimes288e89a2008-01-18 18:24:07 +00006401 added.
6402
Christian Heimesc94e2b52008-01-14 04:13:37 +00006403- sys.float_info / PyFloat_GetInfo: The floating point information
6404 object was converted from a dict to a specialized structseq object.
6405
Georg Brandl3ee81df2008-05-17 18:14:43 +00006406- Patch #1816: Added sys.flags structseq. It exposes the status of
6407 most command line arguments and PYTHON* environment variables.
Christian Heimesf31b69f2008-01-14 03:42:48 +00006408
Georg Brandl3ee81df2008-05-17 18:14:43 +00006409- Objects/structseq.c: Implemented new structseq representation. The
6410 patch makes structseqs (e.g. the return value of os.stat) more
6411 readable.
Christian Heimes9c201962008-01-14 03:33:52 +00006412
Georg Brandl3ee81df2008-05-17 18:14:43 +00006413- Patch #1700288: added a type attribute cache that caches method

Georg Brandl3ee81df2008-05-17 18:14:43 +00006425- Improve some exception messages when Windows fails to load an
6426 extension module. Now we get for example '%1 is not a valid Win32
6427 application' instead of 'error code 193'.

Christian Heimes0a8143f2007-12-18 23:22:54 +00006437
Georg Brandl3ee81df2008-05-17 18:14:43 +00006438- Compiler now generates simpler and faster code for dictionary
6439 literals. The oparg for BUILD_MAP now indicates an estimated
6440 dictionary size. There is a new opcode, STORE_MAP, for adding
6441 entries to the dictionary.

Georg Brandl3ee81df2008-05-17 18:14:43 +00006470- Patch #1739468: Directories and zipfiles containing a __main__.py
6471 file can now be directly executed by passing their name to the
6472 interpreter. The directory/zipfile is automatically inserted as the
6473 first entry in sys.path.

Georg Brandl3ee81df2008-05-17 18:14:43 +00006475- Issue #1265: Fix a problem with sys.settrace, if the tracing
6476 function uses a generator expression when at the same time the
6477 executed code is closing a paused generator.

6484
Georg Brandl21e99f42010-03-07 15:23:59 +00006485- The enumerate() built-in function is no longer bounded to sequences
Georg Brandl3ee81df2008-05-17 18:14:43 +00006486 smaller than LONG_MAX. Formerly, it raised an OverflowError. Now,
6487 automatically shifts from ints to longs.
Raymond Hettinger8f669372007-10-03 21:18:11 +00006488
Georg Brandl3ee81df2008-05-17 18:14:43 +00006489- Issue #1686386: Tuple's tp_repr did not take into account the
6490 possibility of having a self-referential tuple, which is possible
6491 from C code. Nor did object's tp_str consider that a type's tp_str
6492 could do something that could lead to an inifinite recursion.
6493 Py_ReprEnter() and Py_EnterRecursiveCall(), respectively, fixed the
6494 issues.
Brett Cannon0b14f242007-09-30 19:45:10 +00006495
Georg Brandl3ee81df2008-05-17 18:14:43 +00006496- Issue #1164: It was possible to trigger deadlock when using the
6497 'print' statement to write to a file since the GIL was not released
6498 as needed. Now PyObject_Print() does the right thing along with
6499 various tp_print implementations of the built-in types and those in
6500 the collections module.
Brett Cannon01531592007-09-17 03:28:34 +00006501
Georg Brandl3ee81df2008-05-17 18:14:43 +00006502- Issue #1147: Exceptions were directly allowing string exceptions in

Brett Cannon1e534b52007-09-07 04:18:30 +00006509- Issue #1202533: Fix infinite recursion calls triggered by calls to
Georg Brandl3ee81df2008-05-17 18:14:43 +00006510 PyObject_Call() never calling back out to Python code to trigger
6511 recursion depth updates/checks. Required the creation of a static
6512 RuntimeError instance in case normalizing an exception put the
6513 recursion check value past its limit. Fixes crashers
6514 infinite_rec_(1|2|4|5).py.

Neal Norwitz0ac60192007-05-27 04:08:54 +00006529- Add new attribute names for function objects. All the func_* become
Georg Brandl3ee81df2008-05-17 18:14:43 +00006530 __*__ attributes. (Some already existed, e.g., __doc__ and
6531 __name__.)

6537 calls.
6538
Collin Winter62903052007-05-18 23:11:24 +00006539- except clauses may now be spelled either "except E, target:" or
Georg Brandl3ee81df2008-05-17 18:14:43 +00006540 "except E as target:". This is to provide forwards compatibility
6541 with Python 3.0.

6550
Raymond Hettinger13936692007-04-11 18:40:58 +00006551- Request #1191699: Slices can now be pickled.
6552
Raymond Hettinger4db5fe92007-04-12 04:10:00 +00006553- Request #1193128: str.translate() now allows a None argument for

6555 remaining characters.
6556
Georg Brandl5cb76c12007-03-21 09:00:39 +00006557- Patch #1682205: a TypeError while unpacking an iterable is no longer

6561
Guido van Rossum143b5642007-03-23 04:58:42 +00006562- Bug #1683368: The object.__init__() and object.__new__() methods are
6563 now stricter in rejecting excess arguments. The only time when
6564 either allows excess arguments is when it is not overridden and the
6565 other one is. For backwards compatibility, when both are
6566 overridden, it is a deprecation warning (for now; maybe a Py3k
Guido van Rossum234b1ff2007-03-23 19:39:01 +00006567 warning later). Also, type.__init__() insists on the same signature
6568 as supported by type.__new__().
Guido van Rossum143b5642007-03-23 04:58:42 +00006569
Georg Brandl3ee81df2008-05-17 18:14:43 +00006570- Patch #1675423: PyComplex_AsCComplex() now tries to convert an
6571 object to complex using its __complex__() method before falling back
6572 to the __float__() method. Therefore, the functions in the cmath
6573 module now can operate on objects that define a __complex__()
6574 method.

6585 its type.

6591
Georg Brandl7b9c5552007-03-12 14:30:05 +00006592- Bug #1678647: write a newline after printing an exception in any
6593 case, even when converting the value to a string failed.
6594
Georg Brandl871f1bc2007-03-12 13:17:36 +00006595- The dir() function has been extended to call the __dir__() method on
Georg Brandl3ee81df2008-05-17 18:14:43 +00006596 its argument, if it exists. If not, it will work like before. This
6597 allows customizing the output of dir() in the presence of a
6598 __getattr__().

Georg Brandl3ee81df2008-05-17 18:14:43 +00006606- Patch #1491866: change the complex() constructor to allow
6607 parthensized forms. This means complex(repr(x)) now works instead of
6608 raising a ValueError.
Collin Wintere38051d2007-03-09 20:33:07 +00006609
Georg Brandlaa2321b2007-03-07 00:40:28 +00006610- Patch #703779: unset __file__ in __main__ after running a file. This
Georg Brandl3ee81df2008-05-17 18:14:43 +00006611 makes the filenames the warning module prints much more sensible
6612 when a PYTHONSTARTUP file is used.

Georg Brandl0fca97a2007-03-05 22:28:08 +00006625- Patch #1674228: when assigning a slice (old-style), check for the
6626 sq_ass_slice instead of the sq_slice slot.
6627
Georg Brandl3ee81df2008-05-17 18:14:43 +00006628- When printing an unraisable error, don't print exceptions. before
6629 the name. This duplicates the behavior whening normally printing
6630 exceptions.

7196
Georg Brandl92a6bae2007-03-13 17:43:32 +00007197- Patch #1603688: ConfigParser.SafeConfigParser now checks values that
Georg Brandl3ee81df2008-05-17 18:14:43 +00007198 are set for invalid interpolation sequences that would lead to

7255 TestCase and TestSuite subclasses (not instances) are no longer
7256 accepted in TestSuite.addTest(). This should cause no
7257 incompatibility since it never made sense with ordinary subclasses
7258 -- the failure just occurred later, with a more cumbersome
7259 exception.

Georg Brandl3ee81df2008-05-17 18:14:43 +00007540- Issue #829951: In the smtplib module, SMTP.starttls() now complies
7541 with RFC 3207 and forgets any knowledge obtained from the server not
7542 obtained from the TLS negotiation itself. Patch contributed by Bill
7543 Fenner.
Gregory P. Smith2b3ba582008-01-17 08:03:17 +00007544
Georg Brandl3ee81df2008-05-17 18:14:43 +00007545- Issue #1339: The smtplib.SMTP class has been refactored a bit such
Gregory P. Smithbde4ae42008-01-17 08:35:49 +00007546 that the SMTP.starttls() caller no longer needs to call ehlo()
7547 beforehand. SMTP.starttls() now raises an exception of the server
Georg Brandl3ee81df2008-05-17 18:14:43 +00007548 does not claim to support starttls. Adds the
7549 SMTP.ehlo_or_helo_if_needed() method. Patch contributed by Bill

7630 complex, tuple, list, dict, set, and frozenset. Formerly, it would
7631 silently miscode subclasses of those types. Now, it raises a

Raymond Hettinger12e94202007-11-07 01:13:09 +00007633

Georg Brandl3ee81df2008-05-17 18:14:43 +00007648 time so that opening a database previously created with the DB_DUP
7649 or DB_DUPSORT flag set will keep the proper behavior on subsequent
7650 opens. Specifically: dictionary assignment to a DB object will
7651 replace all values for a given key when the database allows
7652 duplicate values. DB users should use DB.put(k, v) when they want
7653 to store duplicates; not DB[k] = v.
Gregory P. Smithec10a4a2007-11-05 02:32:26 +00007654

7660 characters with ASCII value less than 32. Also, it correctly quotes
7661 dots only if they occur on a single line, as opposed to the previous
7662 behavior of quoting dots if they are the second character of any
7663 line.
Georg Brandl4aef7272007-03-13 22:49:43 +00007664

Raymond Hettingerdc1d1ba2007-11-07 02:45:46 +00007932- Add a FAST_LOOPS build option that speeds-up looping by trading away
Georg Brandl3ee81df2008-05-17 18:14:43 +00007933 periodic threadstate and signal checking in tight loops. By
7934 default, this option is turned-off. It should only be enabled in
7935 debugged, performance critical applications.

7951 returned by python-config if Python was built with --enable-shared
7952 because that prevented the shared library from being used.

7986-----
7987
Georg Brandl3ee81df2008-05-17 18:14:43 +00007988- Unified naming convention for free lists and their limits. All free
7989 lists in Object/ are named ``free_list``, the counter ``numfree``
7990 and the upper limit is a macro ``PyName_MAXFREELIST`` inside an
7991 #ifndef block.
Christian Heimes5b970ad2008-02-06 13:33:44 +00007992
Georg Brandl3ee81df2008-05-17 18:14:43 +00007993- ``PySet_Add()`` can now modify a newly created frozenset. Similarly
7994 to ``PyTuple_SetItem``, it can be used to populate a brand new
7995 frozenset; but it does not steal a reference to the added item.
Amaury Forgeot d'Arccab3d982008-02-03 22:51:43 +00007996

8004
8005- Issue #1534: Added ``PyFloat_GetMax()``, ``PyFloat_GetMin()`` and
8006 ``PyFloat_GetInfo()`` to the float API.
8007
Georg Brandl3ee81df2008-05-17 18:14:43 +00008008- Issue #1521: On 64bit platforms, using PyArgs_ParseTuple with the t#
8009 of w# format code incorrectly truncated the length to an int, even
8010 when PY_SSIZE_T_CLEAN is set. The str.decode method used to return
8011 incorrect results with huge strings.
Georg Brandl6caad7d2008-01-26 14:19:22 +00008012
Georg Brandl3ee81df2008-05-17 18:14:43 +00008013- Issue #1629: Renamed Py_Size, Py_Type and Py_Refcnt to Py_SIZE,

8031- Fix some leftovers from the conversion from int to Py_ssize_t
8032 (relevant to strings and sequences of more than 2**31 items).
8033
8034- Make _PyGILState_NoteThreadState() static, it was not used anywhere
8035 outside of pystate.c and should not be necessary.
8036
Georg Brandl3ee81df2008-05-17 18:14:43 +00008037- ``PyImport_Import`` and ``PyImport_ImportModule`` now always do
8038 absolute imports. In earlier versions they might have used relative
8039 imports under some conditions.
Christian Heimes000a0742008-01-03 22:16:32 +00008040
Georg Brandl3ee81df2008-05-17 18:14:43 +00008041- Added case insensitive comparison methods ``PyOS_stricmp(char*,
8042 char*)`` and ``PyOS_strnicmp(char*, char*, Py_ssize_t)``.
Christian Heimes000a0742008-01-03 22:16:32 +00008043
Georg Brandl3ee81df2008-05-17 18:14:43 +00008044- Bug #1542693: remove semi-colon at end of PyImport_ImportModuleEx

8052 requires Windows 2000 or greater. The _WINVER and NTDDI_VERSION
8053 macros are set to Win2k for x86/32bit builds and WinXP for AMD64
8054 builds.
Christian Heimes95d64472008-02-09 19:55:22 +00008055

Georg Brandl3ee81df2008-05-17 18:14:43 +00008069- Removed the macfs module. It had been deprecated since Python 2.5.
8070 This lead to the deprecation of macostools.touched() as it relied
8071 solely on macfs and was a no-op under OS X.
