429 incorrect results with recent versions of Clang, as a result of the

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

Ned Deily0d0ea482012-02-10 12:59:06 +0100507- Issue #13590: On OS X 10.7 and 10.6 with Xcode 4.2, building
508 Distutils-based packages with C extension modules may fail because
509 Apple has removed gcc-4.2, the version used to build python.org
510 64-bit/32-bit Pythons. If the user does not explicitly override
511 the default C compiler by setting the CC environment variable,
512 Distutils will now attempt to compile extension modules with clang
513 if gcc-4.2 is required but not found. Also as a convenience, if
514 the user does explicitly set CC, substitute its value as the default
515 compiler in the Distutils LDSHARED configuration variable for OS X.
516 (Note, the python.org 32-bit-only Pythons use gcc-4.0 and the 10.4u
517 SDK, neither of which are available in Xcode 4. This change does not
518 attempt to override settings to support their use with Xcode 4.)

Ned Deily87e82bb2011-06-28 19:52:59 -0700791- Issue #9516: On Mac OS X, change Distutils to no longer globally attempt to
792 check or set the MACOSX_DEPLOYMENT_TARGET environment variable for the
793 interpreter process. This could cause failures in non-Distutils subprocesses
794 and was unreliable since tests or user programs could modify the interpreter
795 environment after Distutils set it. Instead, have Distutils set the the
796 deployment target only in the environment of each build subprocess. It is
797 still possible to globally override the default by setting
798 MACOSX_DEPLOYMENT_TARGET before launching the interpreter; its value must be
799 greater or equal to the default value, the value with which the interpreter
800 was built.

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

1752 with invalid characters after '=' in a Q-encoded word.
1753
Antoine Pitrou66b5df62010-09-27 18:16:46 +00001754- Issue #9950: Fix socket.sendall() crash or misbehaviour when a signal is
1755 received. Now sendall() properly calls signal handlers if necessary,
1756 and retries sending if these returned successfully, including on sockets
1757 with a timeout.

Antoine Pitrouf7f390a2010-09-14 14:37:18 +00001770- Issue #9729: Fix the signature of SSLSocket.recvfrom() and
1771 SSLSocket.sendto() to match the corresponding socket methods. Also,
1772 fix various SSLSocket methods to raise socket.error rather than an

1774 by Andrew Bennetts.

1783
Raymond Hettinger20397532010-09-12 02:11:45 +00001784- Issue #9825: removed __del__ from the definition of collections.OrderedDict.
1785 This prevents user-created self-referencing ordered dictionaries from
1786 becoming permanently uncollectable GC garbage. The downside is that
1787 removing __del__ means that the internal doubly-linked list has to wait for
1788 GC collection rather than freeing memory immediately when the refcnt drops
1789 to zero.
1790

1794
Antoine Pitrouc818ed42010-09-07 21:40:25 +00001795- Issue #9792: In case of connection failure, socket.create_connection()

1797 to fetch the original errno, or to filter timeout errors. Now the
1798 original error is re-raised.

1818 falling into recursion.
1819
R. David Murray7c4bf552010-08-25 01:45:57 +00001820- Issue #1194222: email.utils.parsedate now returns RFC2822 compliant four
1821 character years even if the message contains RFC822 two character years.
1822
Daniel Stutzbach91287322010-08-24 21:09:30 +00001823- Issue #8750: Fixed MutableSet's methods to correctly handle

1836
Antoine Pitrou3ebaed62010-08-21 19:17:25 +00001837- Issue #9617: Signals received during a low-level write operation aren't
1838 ignored by the buffered IO layer anymore.
1839
Benjamin Peterson52c36052010-08-21 03:03:22 +00001840- Issue #2521: Use weakrefs on for caching in the abc module, so that classes

1842
Raymond Hettingera54b2da2010-08-17 19:03:06 +00001843- Issue #9626: the view methods for collections.OrderedDict() were returning

1852 and a BadZipfile error is raised if it doesn't match (as used to be the
1853 case in Python 2.5 and earlier).
1854
Antoine Pitroucb4f47c2010-08-11 13:40:17 +00001855- Issue #9550: a BufferedReader could issue an additional read when the
1856 original read request had been satisfied, which could block indefinitely
1857 when the underlying raw IO channel was e.g. a socket. Report and original
1858 patch by Jason V. Miller.
1859
Fred Drake0a1fa0e2010-08-10 13:09:54 +00001860- Issue #9551: Don't raise TypeError when setting the value to None for

2251 E.g.: '\xf1\x80AB'.decode('utf-8', 'replace') now returns u'\ufffdAB' and

Mark Dickinsond2f3e3f2010-05-05 22:23:58 +00002609 (Optimization was unintentionally turned on in gcc --with-pydebug builds in
2610 2.7 beta1 as a result of the issue #1628484 fix, combined with autoconf's
2611 strange choice of default CFLAGS produced by AC_PROG_CC for gcc.)

2631Core and Builtins
2632-----------------
2633
Philip Jenveyaebbaeb2010-04-06 23:24:45 +00002634- Issue #7301: Add environment variable $PYTHONWARNINGS.
2635
Benjamin Peterson3a1dfa22010-04-06 21:50:00 +00002636- Issue #8329: Don't return the same lists from select.select when no fds are
2637 changed.
2638
Georg Brandlfee0f442010-05-22 21:26:21 +00002639- Issue #8259: ``1L << (2**31)`` no longer produces an 'outrageous shift error'
Mark Dickinson82791672010-04-06 16:47:55 +00002640 on 64-bit machines. The shift count for either left or right shift is
2641 permitted to be up to sys.maxsize.
2642
Benjamin Peterson4ceeeb02010-04-03 22:48:51 +00002643- Ensure that tokenization of identifiers is not affected by locale.
2644
Georg Brandlfee0f442010-05-22 21:26:21 +00002645- Issue #1222585: Added LDCXXSHARED for C++ support. Patch by Arfrever.
Tarek Ziadé00002952010-04-03 08:37:59 +00002646
Benjamin Peterson1c7c11e2010-04-03 01:28:57 +00002647- Raise a TypeError when trying to delete a T_STRING_INPLACE struct member.
2648
Georg Brandlfee0f442010-05-22 21:26:21 +00002649- Issue #7994: Issue a PendingDeprecationWarning if object.__format__ is called
2650 with a non-empty format string. This is an effort to future-proof user
2651 code. If a derived class does not currently implement __format__ but later
2652 adds its own __format__, it would most likely break user code that had
Antoine Pitrou01a196a2011-01-02 20:05:11 +00002653 supplied a format string. This will be changed to a DeprecationWarning in
Georg Brandlfee0f442010-05-22 21:26:21 +00002654 Python 3.3 and it will be an error in Python 3.4.
Eric Smithd44b2fc2010-04-02 12:30:56 +00002655
Antoine Pitroua57df2c2010-03-31 21:32:15 +00002656- Issue #8268: Old-style classes (not just instances) now support weak

2665 arguments to a function correct.
2666
Benjamin Peterson0dee9c12010-03-17 20:41:42 +00002667- Issue #8164: Don't allow lambda functions to have a docstring.
2668
Victor Stinner66644262010-03-10 22:30:19 +00002669- Issue #3137: Don't ignore errors at startup, especially a keyboard interrupt
Georg Brandlba83f822010-03-14 09:50:54 +00002670 (SIGINT). If an error occurs while importing the site module, the error is
2671 printed and Python exits. Initialize the GIL before importing the site
Victor Stinner66644262010-03-10 22:30:19 +00002672 module.

2686
Georg Brandlfee0f442010-05-22 21:26:21 +00002687- Issue #8257: The Decimal construct now accepts a float instance directly,
2688 converting that float to a Decimal of equal value:
Mark Dickinson8a950712010-04-03 15:47:46 +00002689
2690 >>> Decimal(1.1)
2691 Decimal('1.100000000000000088817841970012523233890533447265625')
2692
Raymond Hettinger34c35b22010-04-03 10:22:00 +00002693- collections.Counter() now supports a subtract() method.
2694
Georg Brandlfee0f442010-05-22 21:26:21 +00002695- The functools module now has a total_ordering() class decorator to simplify
2696 the specification of rich comparisons.
Raymond Hettingera551f312010-04-04 18:34:45 +00002697
Georg Brandlfee0f442010-05-22 21:26:21 +00002698- The functools module also adds cmp_to_key() as a tool to transition old-style
2699 comparison functions to new-style key-functions.
Raymond Hettingera551f312010-04-04 18:34:45 +00002700
Georg Brandlfee0f442010-05-22 21:26:21 +00002701- Issue #8294: The Fraction constructor now accepts Decimal and float instances
2702 directly.
Mark Dickinson7c63eee2010-04-02 22:27:36 +00002703
Georg Brandlfee0f442010-05-22 21:26:21 +00002704- Issue #7279: Comparisons involving a Decimal signaling NaN now signal
2705 InvalidOperation instead of returning False. (Comparisons involving a quiet
2706 NaN are unchanged.) Also, Decimal quiet NaNs are now hashable; Decimal
2707 signaling NaNs remain unhashable.
Mark Dickinsone096e822010-04-02 10:17:07 +00002708
Georg Brandlfee0f442010-05-22 21:26:21 +00002709- Issue #2531: Comparison operations between floats and Decimal instances now
2710 return a result based on the numeric values of the operands; previously they
2711 returned an arbitrary result based on the relative ordering of id(float) and
2712 id(Decimal).
Mark Dickinson99d80962010-04-02 08:53:22 +00002713
Barry Warsawf7f2d6f2010-03-31 21:07:16 +00002714- Issue #8233: When run as a script, py_compile.py optionally takes a single
Georg Brandlfee0f442010-05-22 21:26:21 +00002715 argument `-` which tells it to read files to compile from stdin. Each line is
2716 read on demand and the named file is compiled immediately. (Original patch by
2717 Piotr Ożarowski).
Barry Warsawf7f2d6f2010-03-31 21:07:16 +00002718
Georg Brandlfee0f442010-05-22 21:26:21 +00002719- Issue #3135: Add ``inspect.getcallargs()``, which binds arguments to a

Florent Xicluna58b65662010-03-30 16:29:03 +00002722- Backwards incompatible change: Unicode codepoints line tabulation (0x0B) and
2723 form feed (0x0C) are now considered linebreaks, as specified in Unicode
Georg Brandlfee0f442010-05-22 21:26:21 +00002724 Standard Annex #14. See issue #7643. http://www.unicode.org/reports/tr14/
Florent Xicluna22b24382010-03-30 08:24:06 +00002725
Georg Brandlfee0f442010-05-22 21:26:21 +00002726- Comparisons using one of <, <=, >, >= between a complex instance and a
2727 Fractions instance now raise TypeError instead of returning True/False. This
2728 makes Fraction <=> complex comparisons consistent with int <=> complex, float
2729 <=> complex, and complex <=> complex comparisons.
Mark Dickinson9588d992010-03-27 11:14:37 +00002730

Antoine Pitrou513d9ae2010-03-22 19:59:46 +00002740- Issue #7512: shutil.copystat() could raise an OSError when the filesystem
Georg Brandlfee0f442010-05-22 21:26:21 +00002741 didn't support chflags() (for example ZFS under FreeBSD). The error is now
2742 silenced.
Antoine Pitrou513d9ae2010-03-22 19:59:46 +00002743
Florent Xicluna9e7a4c92010-03-22 16:07:38 +00002744- Issue #7703: ctypes supports both buffer() and memoryview(). The former is

Vinay Sajipecfa08f2010-03-12 09:16:10 +00002784- Issue #8117: logging: Improved algorithm for computing initial rollover time
Georg Brandlfee0f442010-05-22 21:26:21 +00002785 for ``TimedRotatingFileHandler`` by using the modification time of an existing
2786 log file to compute the next rollover time. If the log file does not exist,
2787 the current time is used as the basis for the computation.
Vinay Sajip9098ee42010-03-12 06:01:21 +00002788

2829 integer format code, struct.pack first attempts to convert the non-integer

Georg Brandlba83f822010-03-14 09:50:54 +00002833- Issue #1530559: When passing a non-integer argument to struct.pack with *any*
2834 integer format code (one of 'bBhHiIlLqQ'), struct.pack attempts to use the
2835 argument's __int__ method to convert to an integer before packing. It also
Georg Brandlfee0f442010-05-22 21:26:21 +00002836 produces a DeprecationWarning in this case. (In Python 2.6, the behaviour was
2837 inconsistent: __int__ was used for some integer codes but not for others, and
2838 the set of integer codes for which it was used differed between native packing
2839 and standard packing.)

Georg Brandlba83f822010-03-14 09:50:54 +00003147 file position when calling `truncate()`. It would previously change the file
3148 position to the given argument, which goes against the tradition of
Antoine Pitrouf3fa0742010-01-31 22:26:04 +00003149 ftruncate() and other truncation APIs. Patch by Pascal Chambon.
3150

3152 class used to represent files stored inside an archive. The new
3153 implementation is significantly faster and can be wrapped in a
3154 ``io.BufferedReader`` object for more speedups. It also solves an issue
3155 where interleaved calls to ``read()`` and ``readline()`` give wrong results.
3156 Patch by Nir Aides.

Georg Brandlba83f822010-03-14 09:50:54 +00003166- Issue #7748: Since unicode values are supported for some metadata options in
3167 Distutils, the DistributionMetadata get_* methods will now return an utf-8
3168 encoded string for them. This ensures that the upload and register commands
3169 send the correct values to PyPI without any error.

Georg Brandlba83f822010-03-14 09:50:54 +00003440- Issue #7117: ``repr(x)`` for a float x returns a result based on the shortest
3441 decimal string that's guaranteed to round back to x under correct rounding
3442 (with round-half-to-even rounding mode). Previously it gave a string based on
3443 rounding x to 17 decimal digits. repr(x) for a complex number behaves
3444 similarly. On platforms where the correctly-rounded strtod and dtoa code is
3445 not supported (see below), repr is unchanged.
Mark Dickinsonb678de82009-11-19 18:41:49 +00003446
Georg Brandlba83f822010-03-14 09:50:54 +00003447- Issue #7117: On almost all platforms: float-to-string and string-to-float
3448 conversions within Python are now correctly rounded. Places these conversions
3449 occur include: str for floats and complex numbers; the float and complex
3450 constructors; old-style and new-style numeric formatting; serialization and
3451 deserialization of floats and complex numbers using marshal, pickle and json;
3452 parsing of float and imaginary literals in Python code; Decimal-to-float
3453 conversion.
Mark Dickinsonb678de82009-11-19 18:41:49 +00003454
Georg Brandlba83f822010-03-14 09:50:54 +00003455 The conversions use a Python-adapted version of David Gay's well-known dtoa.c,
3456 providing correctly-rounded strtod and dtoa C functions. This code is
3457 supported on Windows, and on Unix-like platforms using gcc, icc or suncc as
3458 the C compiler. There may be a small number of platforms on which correct
3459 operation of this code cannot be guaranteed, so the code is not used: notably,
3460 this applies to platforms where the C double format is not IEEE 754 binary64,
3461 and to platforms on x86 hardware where the x87 FPU is set to 64-bit precision
3462 and Python's configure script is unable to determine how to change the FPU
3463 precision. On these platforms conversions use the platform strtod and dtoa,
3464 as before.
Mark Dickinsonb678de82009-11-19 18:41:49 +00003465
Georg Brandlba83f822010-03-14 09:50:54 +00003466- Issue #7117: Backport round implementation from Python 3.x. ``round()`` now
3467 uses the correctly-rounded string <-> float conversions described above (when
3468 available), and so produces correctly rounded results that will display nicely
3469 under the float repr. There are two related small changes: (1) round now
3470 accepts any class with an ``__index__()`` method for its second argument (but
3471 no longer accepts floats for the second argument), and (2) an excessively
3472 large second integer argument (e.g., ``round(1.234, 10**100)``) no longer
3473 raises an exception.

Georg Brandlba83f822010-03-14 09:50:54 +00003616 (1) inf and nan strings with trailing whitespace were incorrectly rejected;
3617 (2) parsing of strings representing infinities and nans was locale aware; and
3618 (3) the interpretation of fromhex('-nan') didn't match that of float('-nan').

Georg Brandlba83f822010-03-14 09:50:54 +00003620- Issue #5920: For ``float.__format__()``, change the behavior with the empty
3621 presentation type (that is, not one of 'e', 'f', 'g', or 'n') to be like 'g'
3622 but with at least one decimal point and with a default precision
3623 of 12. Previously, the behavior the same but with a default precision of 6.
3624 This more closely matches ``str()``, and reduces surprises when adding
3625 alignment flags to the empty presentation type. This also affects the new
3626 complex.__format__ in the same way.
3627
3628- Issue #5890: In subclasses of 'property' the __doc__ attribute was shadowed by

Georg Brandlba83f822010-03-14 09:50:54 +00003766- Issue #1180193: When importing a module from a .pyc (or .pyo) file with an
3767 existing .py counterpart, override the co_filename attributes of all code
3768 objects if the original filename is obsolete (which can happen if the file has

3823
Georg Brandlba83f822010-03-14 09:50:54 +00003824- Issue #4233: Changed semantic of ``_fileio.FileIO``'s ``close()`` method on
3825 file objects with closefd=False. The file descriptor is still kept open but
3826 the file object behaves like a closed file. The ``FileIO`` object also got a
3827 new readonly attribute ``closefd``.

Benjamin Peterson399b1fe2008-10-25 02:53:28 +00003847- Using ``nonlocal`` as a variable name will now raise a Py3k SyntaxWarning

Georg Brandlba83f822010-03-14 09:50:54 +00003850- On windows, ``os.chdir()`` given unicode was not working if
3851 GetCurrentDirectoryW returned a path longer than MAX_PATH. (But It's doubtful
3852 this code path is really executed because I cannot move to such directory on
3853 win2k)

Georg Brandlba83f822010-03-14 09:50:54 +00003855- Issue #4069: When ``set.remove(element)`` is used with a set element, the
3856 element is temporarily replaced with an equivalent frozenset. But the
3857 eventual KeyError would always report the empty ``frozenset()`` as the missing
3858 key. Now it correctly refers to the initial element.

Walter Dörwalded960ac2009-05-03 22:36:33 +00003878- Issue #5108: Handle %s like %S and %R in PyUnicode_FromFormatV(): Call
3879 PyUnicode_DecodeUTF8() once, remember the result and output it in a second
3880 step. This avoids problems with counting UTF-8 bytes that ignores the effect
3881 of using the replace error handler in PyUnicode_DecodeUTF8().
3882
Walter Dörwald726ba8e2009-05-06 14:32:35 +00003883- Issue #3739: The unicode-internal encoder now reports the number of characters

Georg Brandlba83f822010-03-14 09:50:54 +00003886- Issue #2422: When compiled with the ``--with-valgrind`` option, the pymalloc

3888 gives improved memory leak detection when running under Valgrind, while taking
3889 advantage of pymalloc at other times.

Georg Brandlba83f822010-03-14 09:50:54 +00004421- Issue #5679: The methods unittest.TestCase.addCleanup and doCleanups were
4422 added. addCleanup allows you to add cleanup functions that will be called

Georg Brandlba83f822010-03-14 09:50:54 +00005112 leak-chasing test runs give sensible results. The previous method of reaping
5113 threads could return successfully while some Thread objects were still
5114 referenced. This also introduces a new private function: ``thread._count()``.

Guilherme Polo7f146ab2009-06-21 17:22:50 +00005131- Issue #5450: Moved tests involving loading tk from Lib/test/test_tcl to
5132 Lib/lib-tk/test/test_tkinter/test_loadtk. With this, these tests demonstrate
Georg Brandlba83f822010-03-14 09:50:54 +00005133 the same behaviour as test_ttkguionly (and now also test_tk) which is to skip
5134 the tests if DISPLAY is defined but can't be used.

5140 import both normal and optimised versions of modules. test_heapq and
5141 test_warnings have been adjusted to use it, tests for other modules with both
5142 C and Python implementations in the stdlib can be adjusted to use it over

Georg Brandlba83f822010-03-14 09:50:54 +00005151- regrtest no longer treats ImportError as equivalent to SkipTest. Imports that
5152 should cause a test to be skipped are now done using import_module from test
5153 support, which does the conversion.

5255
Amaury Forgeot d'Arc05e34492008-09-10 22:04:45 +00005256- Issue #3743: In a few places, PY_FORMAT_SIZE_T was incorrectly used with
5257 PyString_FromFormat or PyErr_Format to display size_t values. The macro
5258 PY_FORMAT_SIZE_T is designed to select the correct format for the OS
5259 ``printf`` function, whereas PyString_FromFormat has an independent
5260 implementation and uses "%zd" on all platforms for size_t values.
5261 This makes a difference on win64, where ``printf`` needs "%Id" to display
5262 64bit values.

Benjamin Peterson97179b02008-09-09 20:55:01 +00005264- Issue #3634: _weakref.ref(Exception).__init__() gave invalid return value on

5268 object; previously an int would be returned for small values. the __long__
5269 method is allowed to return either an int or a long, but the behaviour of

Vinay Sajip35e3b032008-09-01 14:33:59 +00005281- Issue #2534: speed up isinstance() and issubclass() by 50-70%, so as to
Antoine Pitrou0668c622008-08-26 22:42:08 +00005282 match Python 2.5 speed despite the __instancecheck__ / __subclasscheck__
5283 mechanism. In the process, fix a bug where isinstance() and issubclass(),
5284 when given a tuple of classes as second argument, were looking up
5285 __instancecheck__ / __subclasscheck__ on the tuple rather than on each
5286 type object.

Amaury Forgeot d'Arc293924b2008-09-02 23:19:56 +00005384- Issue #2975: When compiling several extension modules with Visual Studio 2008
5385 from the same python interpreter, some environment variables would grow
5386 without limit.
5387
Benjamin Peterson37346b22008-08-23 20:27:43 +00005388- Issue #3643: Added a few more checks to _testcapi to prevent segfaults by

5404 wrapper for warnings.catch_warnings() that makes it easier to check
5405 that expected warning messages are being reported.

Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00005425What's New in Python 2.6 beta 3?
5426================================
5427
Barry Warsaw07a4a382008-08-21 01:15:08 +00005428*Release date: 20-Aug-2008*
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00005429
5430Core and Builtins
5431-----------------
5432
Guido van Rossumf8402962008-08-20 15:01:50 +00005433- Issue #1878: Remove Py_TPFLAGS_HAVE_VERSION_TAG from
5434 Py_TPFLAGS_DEFAULT when not building the core. This means 3rd party
5435 extensions do not automatically benefit from the class attribute
5436 cache; they will have to explicitly add Py_TPFLAGS_HAVE_VERSION_TAG
5437 to their tp_flags field if they care. This is a backwards
5438 compatibility feature; in 3.0, all types will use the cache by
5439 default.
5440
Benjamin Petersonf647dc12008-08-20 01:27:30 +00005441- Keyword arguments can now follow starred arguments. (``f(a, *args,
5442 keyword=23)`` is now valid syntax.)
5443
Thomas Heller0ad5ae02008-08-19 19:25:04 +00005444- ctypes function pointers that are COM methods have a boolean True
5445 value again.
5446
Martin v. Löwisf91d46a2008-08-12 14:49:50 +00005447- Issue #3139: Make buffer-interface thread-safe wrt. PyArg_ParseTuple,
5448 by denying s# to parse objects that have a releasebuffer procedure,
5449 and introducing s*.
5450
Georg Brandl1e13ea92008-08-11 09:07:59 +00005451- Issue #3537: Fix an assertion failure when an empty but presized dict
5452 object was stored in the freelist.
5453
Mark Dickinsonb6467572008-08-04 21:30:09 +00005454- Issue #1481296: Make long(float('nan')) and int(float('nan')) raise
5455 ValueError consistently across platforms.
5456
Amaury Forgeot d'Arc39fd6722008-07-31 21:28:03 +00005457- Issue #3479: On platforms where sizeof(int) is smaller than sizeof(long)
5458 (64bit Unix, for example), unichr() would truncate its argument and return
5459 u'\x00' for unichr(2**32). Now it properly raises an OverflowError.
5460
Neal Norwitze7d8be82008-07-31 17:17:14 +00005461- Apply security patches from Apple.
5462
Amaury Forgeot d'Arc246daed2008-07-31 00:42:16 +00005463- Issue #2542: Now that issubclass() may call arbitrary code, ensure that
5464 PyErr_ExceptionMatches returns 0 when an exception occurs there.
5465
Antoine Pitrou92f82162008-07-25 22:22:08 +00005466- Issue #1819: function calls with several named parameters are now on
5467 average 35% faster (as measured by pybench).
5468
Amaury Forgeot d'Arce4921fe2008-07-21 22:00:38 +00005469- Issue #2378: An unexpected UnboundLocalError or NameError could appear when
5470 the python debugger steps into a class statement: the free variables (local
5471 variables defined in an outer scope) would be deleted from the outer scope.
5472
Gregory P. Smith0470bab2008-07-22 04:46:32 +00005473- Issue #2620: Overflow checking when allocating or reallocating memory
5474 was not always being done properly in some python types and extension
5475 modules. PyMem_MALLOC, PyMem_REALLOC, PyMem_NEW and PyMem_RESIZE have
5476 all been updated to perform better checks and places in the code that
5477 would previously leak memory on the error path when such an allocation
5478 failed have been fixed.

5481-------
5482
Hirokazu Yamamoto838c79f2008-08-20 13:14:07 +00005483- Issue #3612: Added some missing basic types in ctypes.wintypes.
5484
Benjamin Petersone977ad42008-08-20 01:42:01 +00005485- The methods ``is_in_tuple()``, ``is_vararg()``, and ``is_keywordarg()`` of
5486 symtable.Symbol have been deprecated for removal in 3.0 and the next release.
5487
Amaury Forgeot d'Arc351ffb82008-08-18 19:23:47 +00005488- Issue #2234: distutils failed for some versions of the cygwin compiler. The
5489 version reported by these tools does not necessarily follow the python
5490 version numbering scheme, so the module is less strict when parsing it.
5491
Nick Coghlanf70385a2008-08-18 12:42:46 +00005492- Issue #2235: Added Py3k warnings for types which will become unhashable
5493 under the stricter __hash__ inheritance rules in 3.0. Several types
5494 which did not meet the rules for hash invariants and were already
5495 unhashable in 3.0 have now been explicitly flagged as unhashable in
5496 2.6 as well (collections.Mapping, collections.Set, unittest.TestSuite,
5497 xml.dom.minidom.NamedNodeMap, numbers.Number, UserList.UserList)
5498
Brett Cannon88f801d2008-08-18 00:46:22 +00005499- Update __all__ for cookielib, csv, os, urllib2, and weakref to include things
5500 imported into the module but exposed as part of the module's API.
5501
Brett Cannon7b96f072008-08-18 00:41:11 +00005502- Remove an unneeded import of abc.ABCMeta from 'inspect'.
5503
Brett Cannon46225e72008-08-18 00:36:52 +00005504- Remove unneeded imports of 'sys' and 'warnings' from 'io'.
5505
Brett Cannon25c9d6a2008-08-17 22:10:11 +00005506- Remove unneeded imports of 'warnings' from shelve, filecmp, and dummy_thread.
5507
Hirokazu Yamamoto41a81eb2008-08-17 13:10:46 +00005508- Issue #3575: Incremental decoder's decode function now takes bytearray
5509 by using 's*' instead of 't#'.
5510
Mark Dickinson3e4caeb2009-02-21 20:27:01 +00005511- Issue #2222: Fixed reference leak when occurred os.rename()
Hirokazu Yamamoto7f30a682008-08-17 09:46:56 +00005512 fails unicode conversion on 2nd parameter. (windows only)
5513
Georg Brandl222e2082010-08-01 22:27:39 +00005514- Issue #2464: urllib2 now supports a malformation in the URL received
Facundo Batista94f243a2008-08-17 03:38:39 +00005515 in a redirect.
5516
Brett Cannonabe423e2008-08-16 21:47:07 +00005517- Silence the DeprecationWarning raised when importing mimetools in
Brett Cannon721b1452008-08-16 22:00:27 +00005518 BaseHTTPServer, cgi (and rfc822), httplib.
Brett Cannonabe423e2008-08-16 21:47:07 +00005519
Facundo Batistaeb90b782008-08-16 14:44:07 +00005520- Issue #2776: fixed small issue when handling an URL with double slash
5521 after a 302 response in the case of not going through a proxy.
5522
Antoine Pitroub90a8be2008-08-15 21:03:21 +00005523- Issue #2676: in the email package, content-type parsing was hanging on
5524 pathological input because of quadratic or exponential behaviour of a
5525 regular expression.
5526
Antoine Pitrou11ec65d2008-08-14 21:04:30 +00005527- Issue #3476: binary buffered reading through the new "io" library is now
5528 thread-safe.
5529
Brett Cannonbf3157b2008-08-14 05:00:03 +00005530- Silence the DeprecationWarning of rfc822 when it is imported by mimetools
5531 since mimetools itself is deprecated. Because modules are cached, all
5532 subsequent imports of rfc822 will not raise a visible DeprecationWarning.
5533
Antoine Pitrou9fcd4b32008-08-11 17:21:36 +00005534- Issue #3134: shutil referenced undefined WindowsError symbol.
5535
Robert Schuppenies14646332008-08-10 11:01:53 +00005536- Issue #1342811: Fix leak in Tkinter.Menu.delete. Commands associated to
5537 menu entries were not deleted.
5538
Brett Cannon83e81842008-08-09 23:30:55 +00005539- Copied the implementation of reduce() to _functools.reduce() to have a
5540 version that did not raise a DeprecationWarning under -3.
5541
Antoine Pitrou76b8bee2008-08-09 17:27:23 +00005542- Issue #3205: When iterating over a BZ2File fails allocating memory, raise
5543 a MemoryError rather than silently stop the iteration.
5544
Guido van Rossum59ce9012008-08-09 14:55:34 +00005545- Issue #3487: sre "bytecode" validator. Passing invalid "re-bytecode"
5546 to _sre.compile() will now be rejected. This should not affect anybody
5547 since the re.compile() function never generates invalid re-bytecode.
5548
Skip Montanaroa032bf42008-08-08 22:52:51 +00005549- Issue #3436: Make csv.DictReader's fieldnames attribute a property so that
5550 upon first access it can be automatically initialized from the csv file if
5551 it wasn't initialized during instantiation.
5552
Brett Cannon3aa2a492008-08-06 22:28:09 +00005553- Issue #2338: Create imp.reload() to help with transitioning to Python 3.0 as
5554 the reload() built-in has been removed.
5555
Brett Cannon7e30b672008-08-04 21:52:25 +00005556- Changed code in the following modules/packages to remove warnings raised
Brett Cannonc1b76e42008-08-09 23:06:16 +00005557 while running under the ``-3`` flag: aifc, asynchat, asyncore, bdb, bsddb,

5562 threading, tokenize, traceback, urlparse, wsgiref, xml, xmlrpclib.
Brett Cannon7e30b672008-08-04 21:52:25 +00005563
Lars Gustäbel727bd0b2008-08-02 11:26:39 +00005564- Issue #3039: Fix tarfile.TarFileCompat.writestr() which always
5565 raised an AttributeError.
5566
Benjamin Peterson01a24322008-07-28 23:35:27 +00005567- Issue #2523: Fix quadratic behaviour when read()ing a binary file without
Antoine Pitroude781a42008-08-09 12:43:23 +00005568 asking for a specific length. This problem only affected files opened
5569 using the new "io" module, not the built-in open() function.
Benjamin Peterson01a24322008-07-28 23:35:27 +00005570
Mark Dickinsonfe84cce2008-07-27 06:39:07 +00005571- Issue #3449: Update decimal module to use most recent specification
5572 (v. 1.68) and tests (v. 2.58) from IBM.
5573
Georg Brandl222e2082010-08-01 22:27:39 +00005574- Issue #3437: Bug fix in robotparser parsing of Allow: lines.

5578
Georg Brandlf9efabb2008-07-23 15:16:45 +00005579- Deprecate the "ast" parser function aliases.
5580
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00005581- Issue #3120: On 64-bit Windows the subprocess module was truncating handles.
5582
5583- Issue #3303: Fix a crash in locale.strcoll() when calling it with
5584 invalid arguments.
5585
5586- Issue #3302: Fix several crashes when calling locale's gettext functions
5587 with None arguments.
5588
5589- Issue #3389: Allow resolving dotted names for handlers in logging
5590 configuration files.
5591
5592- Deprecate the sunaudio module for removal in Python 3.0.
5593
Antoine Pitrou5fdfa3e2008-07-25 19:42:26 +00005594- Issue #3394: zipfile.writestr sets external attributes when passed a
5595 file name rather than a ZipInfo instance, so files are extracted with
5596 mode 0600 rather than 000 under Unix.
5597
Gregory P. Smitha36f8fe2008-08-04 00:13:29 +00005598- Issue #1857: subprocess.Popen.poll gained an additional _deadstate keyword
5599 argument in python 2.5, this broke code that subclassed Popen to include its
5600 own poll method. Fixed my moving _deadstate to an _internal_poll method.

5609
Nick Coghlan6e8fef02008-08-18 13:14:22 +00005610- Issue #2235: the C API function PyObject_HashNotImplemented and its
5611 interaction with the tp_hash slot (added in 2.6b2) are now documented
5612
Nick Coghlan2a0c2b12008-08-04 12:47:17 +00005613- Issue #643841: The language reference now provides more detailed
5614 coverage of the lookup process for special methods. The disclaimers
5615 regarding lack of coverage of new-style classes have also been
5616 removed, since the coverage is now fairly reasonable.

Raymond Hettingere3ae6552008-06-20 04:18:15 +00005619What's New in Python 2.6 beta 2?
5620================================
5621
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00005622*Release date: 17-Jul-2008*
5623
Raymond Hettingere3ae6552008-06-20 04:18:15 +00005624Core and Builtins
5625-----------------
5626
Georg Brandl3e483f62008-07-16 22:57:41 +00005627- Issue #3156: Fix inconsistent behavior of the bytearray type: all
5628 its methods now allow for items objects that can be converted to
5629 an integer using operator.index().
5630
Mark Dickinson64b7e502008-07-16 09:40:03 +00005631- Issue #3360: Fix incorrect parsing of '020000000000.0', which
5632 produced a ValueError instead of giving the correct float.
5633
Eric Smitha5fa5a22008-07-16 00:11:49 +00005634- Issue #3083: Add alternate (#) formatting for bin, oct, hex output
5635 for str.format(). This adds the prefix 0b, 0o, or 0x, respectively.
5636
Mark Dickinson7103aa42008-07-15 19:08:33 +00005637- Issue #3008: the float type has a new instance method 'float.hex'
5638 and a new class method 'float.fromhex' to convert floating-point
5639 numbers to and from hexadecimal strings, respectively.
5640
Nick Coghlan6d6bd442008-07-15 15:40:22 +00005641- Issue #2235: __hash__ is once again inherited by default. To allow
5642 collections.Hashable to remain meaningful in the presence of the
5643 default hash implementation (object.__hash__), it is now possible
5644 to explicit block inheritance of hash by setting __hash__=None at
5645 the Python level, or tp_hash=PyObject_HashNotImplemented at the C
5646 level.
5647
Nick Coghlanb028f502008-07-13 14:52:36 +00005648- Issue #3221: Issue a RuntimeWarning instead of raising SystemError if
5649 the parent module cannot be found while performing an absolute import.
5650 This means that an incorrectly defined __package__ attribute will
5651 now only prevent relative imports in that module rather than causing
5652 all imports from that module to fail.
5653
Nick Coghlan14ff9942008-07-08 14:21:42 +00005654- Issue #2517: Allow unicode messages in Exceptions again by correctly
5655 bypassing the instance dictionary when looking up __unicode__ on
5656 new-style classes.
5657
Amaury Forgeot d'Arcbdd941f2008-07-01 20:38:04 +00005658- Issue #3242: Fix a crash inside the print statement, if sys.stdout is
5659 set to a custom object whose write() method happens to install
5660 another file in sys.stdout.
5661
Amaury Forgeot d'Arc1f40c8a2008-06-30 22:42:40 +00005662- Issue #3088: Corrected a race condition in classes derived from
5663 threading.local: the first member set by a thread could be saved in
5664 another thread's dictionary.
5665
Mark Dickinson1ec2fcd2008-06-20 14:53:43 +00005666- Issue #3004: Minor change to slice.indices(): the start and stop
5667 arguments are now treated identically, making the behaviour easier
5668 to describe and understand. For example, slice(None, -10,
5669 1).indices(9) now returns (0, 0, 1) instead of (0, -1, 1), and
5670 slice(None, 10, -1).indices(10) returns (9, 9, -1) instead of (9,
5671 10, -1).
5672
Georg Brandl278fc502008-07-19 12:46:12 +00005673- Issue #3219: Calling a function with repeated keyword arguments,
5674 f(a=2, a=23), would not cause a syntax error. This was a regression

Georg Brandl5cc774e2008-06-11 20:28:06 +00006125 PPC64 and x86_64 support in one binary).
Ronald Oussoren5640ce22008-06-05 12:58:24 +00006126
6127 This is controlled by the configure argument ``--with-universal-archs``:
6128
6129 - ``--with-universal-archs=all``: install 4-way universal
6130
6131 - ``--with-universal-archs=32-bit``: install 2-way universal, 32-bit (the default)
6132
6133 - ``--with-universal-archs=64-bit``: install 2-way universal, 64-bit
6134
6135 This option should be used in combination with ``--enable-universalsdk=``.

Georg Brandl3ee81df2008-05-17 18:14:43 +00006187- Issue #1631171: Re-implement the 'warnings' module in C (the
6188 original Python code has been kept as backup). This will allow for
6189 using the 'warning's machinery in such places as the parser where
6190 use of pure Python code is not possible. Both the ``showarning()``
6191 and ``formatwarning()`` gain an optional 'line' argument which is
6192 not called by default for backwards-compatibility reasons. Setting
6193 ``warnings.showwarning()`` to an implementation that lacks support
6194 for the ``line`` argument will raise a DeprecationWarning.

Georg Brandl3ee81df2008-05-17 18:14:43 +00006257- Issue #2550: The approach used by client/server code for obtaining
6258 ports to listen on in network-oriented tests has been refined in an
6259 effort to facilitate running multiple instances of the entire
6260 regression test suite in parallel without issue.
6261 test_support.bind_port() has been fixed such that it will always
6262 return a unique port -- which wasn't always the case with the
6263 previous implementation, especially if socket options had been set
6264 that affected address reuse (i.e. SO_REUSEADDR, SO_REUSEPORT). The
6265 new implementation of bind_port() will actually raise an exception
6266 if it is passed an AF_INET/SOCK_STREAM socket with either the
6267 SO_REUSEADDR or SO_REUSEPORT socket option set. Furthermore, if
6268 available, bind_port() will set the SO_EXCLUSIVEADDRUSE option on
6269 the socket it's been passed. This currently only applies to
6270 Windows. This option prevents any other sockets from binding to the
6271 host/port we've bound to, thus removing the possibility of the
6272 'non-deterministic' behaviour, as Microsoft puts it, that occurs
6273 when a second SOCK_STREAM socket binds and accepts to a host/port
6274 that's already been bound by another socket. The optional preferred
6275 port parameter to bind_port() has been removed. Under no
6276 circumstances should tests be hard coding ports!
6277
6278 test_support.find_unused_port() has also been introduced, which will
6279 pass a temporary socket object to bind_port() in order to obtain an
6280 unused port. The temporary socket object is then closed and
6281 deleted, and the port is returned. This method should only be used
6282 for obtaining an unused port in order to pass to an external program
6283 (i.e. the -accept [port] argument to openssl's s_server mode) or as
6284 a parameter to a server-oriented class that doesn't give you direct
6285 access to the underlying socket used.
6286
6287 Finally, test_support.HOST has been introduced, which should be used
6288 for the host argument of any relevant socket calls (i.e. bind and
6289 connect).
Trent Nelsone41b0062008-04-08 23:47:30 +00006290
6291 The following tests were updated to following the new conventions:
Georg Brandl3ee81df2008-05-17 18:14:43 +00006292 test_socket, test_smtplib, test_asyncore, test_ssl, test_httplib,
Trent Nelsone41b0062008-04-08 23:47:30 +00006293 test_poplib, test_ftplib, test_telnetlib, test_socketserver,
6294 test_asynchat and test_socket_ssl.
6295
Georg Brandl3ee81df2008-05-17 18:14:43 +00006296 It is now possible for multiple instances of the regression test
6297 suite to run in parallel without issue.

Eric Smitha73fbe72008-02-23 03:09:44 +00006576- Added the future_builtins module, which contains hex() and oct().
6577 These are the PEP 3127 version of these functions, designed to be
6578 compatible with the hex() and oct() builtins from Python 3.0. They
6579 differ slightly in their output formats from the existing, unchanged
6580 Python 2.6 builtins. The expected usage of the future_builtins
6581 module is:
6582 from future_builtins import hex, oct
6583
Eric Smith7ef40bf2008-02-20 23:34:22 +00006584- Issue #1600: Modifed PyOS_ascii_formatd to use at most 2 digit
6585 exponents for exponents with absolute value < 100. Follows C99
6586 standard. This is a change on Windows, which would use 3 digits.
6587 Also, added 'n' to the formats that PyOS_ascii_formatd understands,
6588 so that any alterations it does to the resulting string will be
6589 available in stringlib/formatter.h (for float.__format__).
6590
Eric Smith5a3c1352008-02-19 13:21:56 +00006591- Implemented PEP 3101, Advanced String Formatting. This adds a new
6592 builtin format(); a format() method for str and unicode; a
6593 __format__() method to object, str, unicode, int, long, float, and
6594 datetime; the class string.Formatter; and the C API
6595 PyObject_Format().
6596
Georg Brandl3ee81df2008-05-17 18:14:43 +00006597- Fixed several potential crashes, all caused by specially crafted
6598 __del__ methods exploiting objects in temporarily inconsistent
6599 state.
Amaury Forgeot d'Arc632fad32008-02-16 20:55:24 +00006600
Vinay Sajipb7edfc42008-04-02 21:10:23 +00006601- Issue #2115: Important speedup in setting __slot__ attributes. Also
Georg Brandl3ee81df2008-05-17 18:14:43 +00006602 prevent a possible crash: an Abstract Base Class would try to access
6603 a slot on a registered virtual subclass.
Amaury Forgeot d'Arc60d6c7f2008-02-15 21:22:45 +00006604

Georg Brandl3ee81df2008-05-17 18:14:43 +00006608- Clear all free lists during a gc.collect() of the highest generation
6609 in order to allow pymalloc to free more arenas. Python may give back
6610 memory to the OS earlier.
Christian Heimes3b718a72008-02-14 12:47:33 +00006611
Georg Brandl3ee81df2008-05-17 18:14:43 +00006612- Issue #2045: Fix an infinite recursion triggered when printing a
6613 subclass of collections.defaultdict, if its default_factory is set
6614 to a bound method.
Amaury Forgeot d'Arcb01aa432008-02-08 00:56:02 +00006615
Christian Heimesf75dbef2008-02-08 00:11:31 +00006616- Fixed a minor memory leak in dictobject.c. The content of the free
6617 list was not freed on interpreter shutdown.
6618
Georg Brandl21e99f42010-03-07 15:23:59 +00006619- Limit free list of method and built-in function objects to 256
Georg Brandl3ee81df2008-05-17 18:14:43 +00006620 entries each.
Christian Heimes6075a822008-02-06 12:44:34 +00006621
Georg Brandl3ee81df2008-05-17 18:14:43 +00006622- Patch #1953: Added ``sys._compact_freelists()`` and the C API
6623 functions ``PyInt_CompactFreeList`` and ``PyFloat_CompactFreeList``
Christian Heimes422051a2008-02-04 18:00:12 +00006624 to compact the internal free lists of pre-allocted ints and floats.
6625
Georg Brandl3ee81df2008-05-17 18:14:43 +00006626- Issue #1983: Fixed return type of fork(), fork1() and forkpty()
6627 calls. Python expected the return type int but the fork familie
6628 returns pi_t.
Christian Heimes951cc0f2008-01-31 23:08:23 +00006629
Georg Brandl3ee81df2008-05-17 18:14:43 +00006630- Issue #1678380: Fix a bug that identifies 0j and -0j when they

Georg Brandl3ee81df2008-05-17 18:14:43 +00006642- Patch #1473257: generator objects gain a gi_code attribute. This is
6643 the same object as the func_code attribute of the function that
6644 produced the generator.
Georg Brandl0cdf9a32008-01-26 14:14:20 +00006645
Georg Brandl3ee81df2008-05-17 18:14:43 +00006646- Issue #1920: "while 0" statements were completely removed by the
6647 compiler, even in the presence of an "else" clause, which is
6648 supposed to be run when the condition is false. Now the compiler
6649 correctly emits bytecode for the "else" suite.
Amaury Forgeot d'Arc31eaafe2008-01-24 22:59:25 +00006650
Guido van Rossumeead05f2008-01-24 18:21:02 +00006651- A few crashers fixed: weakref_in_del.py (issue #1377858);
6652 loosing_dict_ref.py (issue #1303614, test67.py);
6653 borrowed_ref_[34].py (not in tracker).
6654
Vinay Sajipd7cf32e2008-01-24 12:43:33 +00006655- Issue #1069410: The "can't load dll" message box on Windows is
Christian Heimesb2302ba2008-01-23 17:15:06 +00006656 suppressed while an extension is loaded by calling SetErrorMode in
6657 dynload_win.c. The error is still reported properly.
6658
Georg Brandl3ee81df2008-05-17 18:14:43 +00006659- Issue #1915: Python compiles with --enable-unicode=no again. However
Christian Heimes082c9b02008-01-23 14:20:50 +00006660 several extension methods and modules do not work without unicode
6661 support.
6662
Georg Brandl26543b12008-01-21 18:36:51 +00006663- Issue #1882: when compiling code from a string, encoding cookies in the
6664 second line of code were not always recognized correctly.
6665
Georg Brandl14404b62008-01-19 19:27:05 +00006666- Issue #1679: "0x" was taken as a valid integer literal.
6667
Georg Brandl6caad7d2008-01-26 14:19:22 +00006668- Issue #1865: ``bytes`` as an alias for ``str`` and b"" as an alias "" were
Christian Heimes288e89a2008-01-18 18:24:07 +00006669 added.
6670
Christian Heimesc94e2b52008-01-14 04:13:37 +00006671- sys.float_info / PyFloat_GetInfo: The floating point information
6672 object was converted from a dict to a specialized structseq object.
6673
Georg Brandl3ee81df2008-05-17 18:14:43 +00006674- Patch #1816: Added sys.flags structseq. It exposes the status of
6675 most command line arguments and PYTHON* environment variables.
Christian Heimesf31b69f2008-01-14 03:42:48 +00006676
Georg Brandl3ee81df2008-05-17 18:14:43 +00006677- Objects/structseq.c: Implemented new structseq representation. The

Georg Brandl3ee81df2008-05-17 18:14:43 +00006703 and INF. float("nan"), float("inf") and float("-inf") now work on
6704 every platform with IEEE 754 semantics.
Christian Heimes0a8143f2007-12-18 23:22:54 +00006705
Georg Brandl3ee81df2008-05-17 18:14:43 +00006706- Compiler now generates simpler and faster code for dictionary
6707 literals. The oparg for BUILD_MAP now indicates an estimated
6708 dictionary size. There is a new opcode, STORE_MAP, for adding
6709 entries to the dictionary.

Georg Brandl3ee81df2008-05-17 18:14:43 +00006738- Patch #1739468: Directories and zipfiles containing a __main__.py
6739 file can now be directly executed by passing their name to the
6740 interpreter. The directory/zipfile is automatically inserted as the
6741 first entry in sys.path.

Georg Brandl3ee81df2008-05-17 18:14:43 +00006743- Issue #1265: Fix a problem with sys.settrace, if the tracing
6744 function uses a generator expression when at the same time the
6745 executed code is closing a paused generator.
Amaury Forgeot d'Arc0d75f092007-11-13 21:54:28 +00006746
Raymond Hettinger1760c8a2007-11-08 02:52:43 +00006747- sets and frozensets now have an isdisjoint() method.

Neal Norwitz44f326e2007-10-05 05:29:17 +00006751- Fix warnings found by the new version of the Coverity checker.
6752
Georg Brandl21e99f42010-03-07 15:23:59 +00006753- The enumerate() built-in function is no longer bounded to sequences
Georg Brandl3ee81df2008-05-17 18:14:43 +00006754 smaller than LONG_MAX. Formerly, it raised an OverflowError. Now,
6755 automatically shifts from ints to longs.
Raymond Hettinger8f669372007-10-03 21:18:11 +00006756
Georg Brandl3ee81df2008-05-17 18:14:43 +00006757- Issue #1686386: Tuple's tp_repr did not take into account the
6758 possibility of having a self-referential tuple, which is possible
6759 from C code. Nor did object's tp_str consider that a type's tp_str
6760 could do something that could lead to an inifinite recursion.
6761 Py_ReprEnter() and Py_EnterRecursiveCall(), respectively, fixed the
6762 issues.
Brett Cannon0b14f242007-09-30 19:45:10 +00006763
Georg Brandl3ee81df2008-05-17 18:14:43 +00006764- Issue #1164: It was possible to trigger deadlock when using the
6765 'print' statement to write to a file since the GIL was not released
6766 as needed. Now PyObject_Print() does the right thing along with
6767 various tp_print implementations of the built-in types and those in
6768 the collections module.
Brett Cannon01531592007-09-17 03:28:34 +00006769
Georg Brandl3ee81df2008-05-17 18:14:43 +00006770- Issue #1147: Exceptions were directly allowing string exceptions in
6771 their throw() method even though string exceptions no longer
6772 allowed.
Brett Cannon4c20bc42007-09-11 21:02:28 +00006773
Georg Brandl3ee81df2008-05-17 18:14:43 +00006774- Issue #1096: Prevent a segfault from getting the repr of a very
6775 deeply nested list by using the recursion counter.
Brett Cannona0c05512007-09-10 21:38:27 +00006776
Brett Cannon1e534b52007-09-07 04:18:30 +00006777- Issue #1202533: Fix infinite recursion calls triggered by calls to
Georg Brandl3ee81df2008-05-17 18:14:43 +00006778 PyObject_Call() never calling back out to Python code to trigger
6779 recursion depth updates/checks. Required the creation of a static
6780 RuntimeError instance in case normalizing an exception put the
6781 recursion check value past its limit. Fixes crashers
6782 infinite_rec_(1|2|4|5).py.
Brett Cannon1e534b52007-09-07 04:18:30 +00006783
Georg Brandl3ee81df2008-05-17 18:14:43 +00006784- Patch #1031213: Decode source line in SyntaxErrors back to its

Neal Norwitz0ac60192007-05-27 04:08:54 +00006797- Add new attribute names for function objects. All the func_* become
Georg Brandl3ee81df2008-05-17 18:14:43 +00006798 __*__ attributes. (Some already existed, e.g., __doc__ and
6799 __name__.)
Neal Norwitz0ac60192007-05-27 04:08:54 +00006800
Neal Norwitz8b2bfbc2007-05-23 06:35:32 +00006801- Add -3 option to the interpreter to warn about features that are
6802 deprecated and will be changed/removed in Python 3.0.
6803
Georg Brandl2134e752007-05-21 20:34:16 +00006804- Patch #1686487: you can now pass any mapping after '**' in function
6805 calls.
6806
Collin Winter62903052007-05-18 23:11:24 +00006807- except clauses may now be spelled either "except E, target:" or
Georg Brandl3ee81df2008-05-17 18:14:43 +00006808 "except E as target:". This is to provide forwards compatibility
6809 with Python 3.0.
Collin Winter62903052007-05-18 23:11:24 +00006810
Brett Cannon229cee22007-05-05 01:34:02 +00006811- Deprecate BaseException.message as per PEP 352.
6812
Georg Brandl3ee81df2008-05-17 18:14:43 +00006813- Issue #1303614: don't expose object's __dict__ when the dict is
Georg Brandl21e99f42010-03-07 15:23:59 +00006814 inherited from a built-in base.
Armin Rigo9790a272007-05-02 19:23:31 +00006815
Vinay Sajip8549ce32007-05-06 17:53:37 +00006816- When __slots__ are set to a unicode string, make it work the same as
Neal Norwitzcbd9ee62007-04-14 05:25:50 +00006817 setting a plain string, ie don't expand to single letter identifiers.
6818
Raymond Hettinger13936692007-04-11 18:40:58 +00006819- Request #1191699: Slices can now be pickled.
6820
Raymond Hettinger4db5fe92007-04-12 04:10:00 +00006821- Request #1193128: str.translate() now allows a None argument for
6822 translations that only remove characters without re-mapping the
6823 remaining characters.
6824
Georg Brandl5cb76c12007-03-21 09:00:39 +00006825- Patch #1682205: a TypeError while unpacking an iterable is no longer
6826 masked by a generic one with the message "unpack non-sequence".
6827
Neal Norwitzaa754b72007-03-21 06:39:48 +00006828- Remove unused file Python/fmod.c.
6829
Guido van Rossum143b5642007-03-23 04:58:42 +00006830- Bug #1683368: The object.__init__() and object.__new__() methods are
6831 now stricter in rejecting excess arguments. The only time when
6832 either allows excess arguments is when it is not overridden and the
6833 other one is. For backwards compatibility, when both are
6834 overridden, it is a deprecation warning (for now; maybe a Py3k
Guido van Rossum234b1ff2007-03-23 19:39:01 +00006835 warning later). Also, type.__init__() insists on the same signature
6836 as supported by type.__new__().
Guido van Rossum143b5642007-03-23 04:58:42 +00006837
Georg Brandl3ee81df2008-05-17 18:14:43 +00006838- Patch #1675423: PyComplex_AsCComplex() now tries to convert an
6839 object to complex using its __complex__() method before falling back
6840 to the __float__() method. Therefore, the functions in the cmath
6841 module now can operate on objects that define a __complex__()
6842 method.
Georg Brandl2b869942007-03-17 16:08:45 +00006843
Georg Brandl3ee81df2008-05-17 18:14:43 +00006844- Patch #1623563: allow __class__ assignment for classes with
6845 __slots__. The old and the new class are still required to have the
6846 same slot names.
Žiga Seilnacht6f2d09c2007-03-16 11:59:38 +00006847

6852 ``object.__reduce_ex__()`` is called with an object that is faking
6853 its type.
Žiga Seilnacht20f43d32007-03-15 11:44:55 +00006854
Georg Brandl3ee81df2008-05-17 18:14:43 +00006855- Patch #1680015: Don't modify __slots__ tuple if it contains an

6859
Georg Brandl7b9c5552007-03-12 14:30:05 +00006860- Bug #1678647: write a newline after printing an exception in any
6861 case, even when converting the value to a string failed.
6862
Georg Brandl871f1bc2007-03-12 13:17:36 +00006863- The dir() function has been extended to call the __dir__() method on
Georg Brandl3ee81df2008-05-17 18:14:43 +00006864 its argument, if it exists. If not, it will work like before. This
6865 allows customizing the output of dir() in the presence of a
6866 __getattr__().

Collin Winter276887b2007-03-12 16:11:39 +00006868- Patch #922167: Python no longer segfaults when faced with infinitely
6869 self-recursive reload() calls (as reported by bug #742342).
6870
Georg Brandl3ee81df2008-05-17 18:14:43 +00006871- Patch #1675981: remove unreachable code from ``type.__new__()``
6872 method.

Georg Brandl3ee81df2008-05-17 18:14:43 +00006874- Patch #1491866: change the complex() constructor to allow
6875 parthensized forms. This means complex(repr(x)) now works instead of
6876 raising a ValueError.
Collin Wintere38051d2007-03-09 20:33:07 +00006877
Georg Brandlaa2321b2007-03-07 00:40:28 +00006878- Patch #703779: unset __file__ in __main__ after running a file. This
Georg Brandl3ee81df2008-05-17 18:14:43 +00006879 makes the filenames the warning module prints much more sensible
6880 when a PYTHONSTARTUP file is used.
Georg Brandlaa2321b2007-03-07 00:40:28 +00006881

6883 exception if the -i command line option or PYTHONINSPECT environment
Georg Brandl3ee81df2008-05-17 18:14:43 +00006884 variable is given, but break into the interactive interpreter just
6885 like on other exceptions or normal program exit.

6891 condition.
Georg Brandl098cd692007-03-06 12:17:50 +00006892
Georg Brandl0fca97a2007-03-05 22:28:08 +00006893- Patch #1674228: when assigning a slice (old-style), check for the
6894 sq_ass_slice instead of the sq_slice slot.
6895
Georg Brandl3ee81df2008-05-17 18:14:43 +00006896- When printing an unraisable error, don't print exceptions. before
6897 the name. This duplicates the behavior whening normally printing
6898 exceptions.

7523 TestCase and TestSuite subclasses (not instances) are no longer
7524 accepted in TestSuite.addTest(). This should cause no

7526 -- the failure just occurred later, with a more cumbersome
7527 exception.

Georg Brandl3ee81df2008-05-17 18:14:43 +00007808- Issue #829951: In the smtplib module, SMTP.starttls() now complies
7809 with RFC 3207 and forgets any knowledge obtained from the server not
7810 obtained from the TLS negotiation itself. Patch contributed by Bill
7811 Fenner.
Gregory P. Smith2b3ba582008-01-17 08:03:17 +00007812
Georg Brandl3ee81df2008-05-17 18:14:43 +00007813- Issue #1339: The smtplib.SMTP class has been refactored a bit such
Gregory P. Smithbde4ae42008-01-17 08:35:49 +00007814 that the SMTP.starttls() caller no longer needs to call ehlo()
7815 beforehand. SMTP.starttls() now raises an exception of the server
Georg Brandl3ee81df2008-05-17 18:14:43 +00007816 does not claim to support starttls. Adds the
7817 SMTP.ehlo_or_helo_if_needed() method. Patch contributed by Bill

7898 complex, tuple, list, dict, set, and frozenset. Formerly, it would
7899 silently miscode subclasses of those types. Now, it raises a

Raymond Hettinger12e94202007-11-07 01:13:09 +00007901

Georg Brandl3ee81df2008-05-17 18:14:43 +00007916 time so that opening a database previously created with the DB_DUP
7917 or DB_DUPSORT flag set will keep the proper behavior on subsequent
7918 opens. Specifically: dictionary assignment to a DB object will
7919 replace all values for a given key when the database allows
7920 duplicate values. DB users should use DB.put(k, v) when they want
7921 to store duplicates; not DB[k] = v.
Gregory P. Smithec10a4a2007-11-05 02:32:26 +00007922

7928 characters with ASCII value less than 32. Also, it correctly quotes
7929 dots only if they occur on a single line, as opposed to the previous
7930 behavior of quoting dots if they are the second character of any
7931 line.
Georg Brandl4aef7272007-03-13 22:49:43 +00007932

Raymond Hettingerdc1d1ba2007-11-07 02:45:46 +00008200- Add a FAST_LOOPS build option that speeds-up looping by trading away
Georg Brandl3ee81df2008-05-17 18:14:43 +00008201 periodic threadstate and signal checking in tight loops. By
8202 default, this option is turned-off. It should only be enabled in
8203 debugged, performance critical applications.

8255
Georg Brandl3ee81df2008-05-17 18:14:43 +00008256- Unified naming convention for free lists and their limits. All free
8257 lists in Object/ are named ``free_list``, the counter ``numfree``

8259 #ifndef block.
Christian Heimes5b970ad2008-02-06 13:33:44 +00008260
Georg Brandl3ee81df2008-05-17 18:14:43 +00008261- ``PySet_Add()`` can now modify a newly created frozenset. Similarly
8262 to ``PyTuple_SetItem``, it can be used to populate a brand new
8263 frozenset; but it does not steal a reference to the added item.

8275
Georg Brandl3ee81df2008-05-17 18:14:43 +00008276- Issue #1521: On 64bit platforms, using PyArgs_ParseTuple with the t#
8277 of w# format code incorrectly truncated the length to an int, even
8278 when PY_SSIZE_T_CLEAN is set. The str.decode method used to return
8279 incorrect results with huge strings.
Georg Brandl6caad7d2008-01-26 14:19:22 +00008280
Georg Brandl3ee81df2008-05-17 18:14:43 +00008281- Issue #1629: Renamed Py_Size, Py_Type and Py_Refcnt to Py_SIZE,

8301
8302- Make _PyGILState_NoteThreadState() static, it was not used anywhere
8303 outside of pystate.c and should not be necessary.
8304
Georg Brandl3ee81df2008-05-17 18:14:43 +00008305- ``PyImport_Import`` and ``PyImport_ImportModule`` now always do
8306 absolute imports. In earlier versions they might have used relative
8307 imports under some conditions.
Christian Heimes000a0742008-01-03 22:16:32 +00008308
Georg Brandl3ee81df2008-05-17 18:14:43 +00008309- Added case insensitive comparison methods ``PyOS_stricmp(char*,
8310 char*)`` and ``PyOS_strnicmp(char*, char*, Py_ssize_t)``.
Christian Heimes000a0742008-01-03 22:16:32 +00008311
Georg Brandl3ee81df2008-05-17 18:14:43 +00008312- Bug #1542693: remove semi-colon at end of PyImport_ImportModuleEx

8322 builds.
Christian Heimes95d64472008-02-09 19:55:22 +00008323

Georg Brandl3ee81df2008-05-17 18:14:43 +00008337- Removed the macfs module. It had been deprecated since Python 2.5.
8338 This lead to the deprecation of macostools.touched() as it relied
8339 solely on macfs and was a no-op under OS X.
