Ned Deily18fae3f2013-01-31 01:24:55 -0800925- Issue #13590: OS X Xcode 4 - improve support for universal extension modules
926 In particular, fix extension module build failures when trying to use
927 32-bit-only installer Pythons on systems with Xcode 4 (currently
928 OS X 10.8, 10.7, and optionally 10.6).
929 * Backport 3.3.0 fixes to 2.7 branch (for release in 2.7.4)
930 * Since Xcode 4 removes ppc support, extension module builds now
931 check for ppc compiler support and by default remove ppc and
932 ppc64 archs when they are not available.
933 * Extension module builds now revert to using system installed
934 headers and libs (/usr and /System/Library) if the SDK used
935 to build the interpreter is not installed or has moved.
936 * Try to avoid building extension modules with deprecated
937 and problematic Apple llvm-gcc compiler. If original compiler
938 is not available, use clang instead by default.

1293 in list_repeat (listobject.c) and islice_next (itertoolsmodule.c). These

Ned Deily0d0ea482012-02-10 12:59:06 +01001369- Issue #13590: On OS X 10.7 and 10.6 with Xcode 4.2, building
1370 Distutils-based packages with C extension modules may fail because
1371 Apple has removed gcc-4.2, the version used to build python.org
1372 64-bit/32-bit Pythons. If the user does not explicitly override
1373 the default C compiler by setting the CC environment variable,
1374 Distutils will now attempt to compile extension modules with clang
1375 if gcc-4.2 is required but not found. Also as a convenience, if
1376 the user does explicitly set CC, substitute its value as the default
1377 compiler in the Distutils LDSHARED configuration variable for OS X.
1378 (Note, the python.org 32-bit-only Pythons use gcc-4.0 and the 10.4u
1379 SDK, neither of which are available in Xcode 4. This change does not
1380 attempt to override settings to support their use with Xcode 4.)

Ned Deily87e82bb2011-06-28 19:52:59 -07001630- Issue #9516: On Mac OS X, change Distutils to no longer globally attempt to
1631 check or set the MACOSX_DEPLOYMENT_TARGET environment variable for the
1632 interpreter process. This could cause failures in non-Distutils subprocesses
1633 and was unreliable since tests or user programs could modify the interpreter
Ezio Melotti302ad8d2013-01-19 19:44:58 +02001634 environment after Distutils set it. Instead, have Distutils set the
Ned Deily87e82bb2011-06-28 19:52:59 -07001635 deployment target only in the environment of each build subprocess. It is
1636 still possible to globally override the default by setting
1637 MACOSX_DEPLOYMENT_TARGET before launching the interpreter; its value must be
1638 greater or equal to the default value, the value with which the interpreter
1639 was built.

1669 the ticker doesn't have to wind down to zero from the old starting point
1670 before the new interval takes effect. And if the user increases the
1671 interval, it makes sure the new limit takes effect right away rather have an
1672 early task switch before recognizing the new interval.

2642 by Andrew Bennetts.

2651
Raymond Hettinger20397532010-09-12 02:11:45 +00002652- Issue #9825: removed __del__ from the definition of collections.OrderedDict.
2653 This prevents user-created self-referencing ordered dictionaries from
2654 becoming permanently uncollectable GC garbage. The downside is that
2655 removing __del__ means that the internal doubly-linked list has to wait for
2656 GC collection rather than freeing memory immediately when the refcnt drops
2657 to zero.

Ezio Melottiab2eb0e2010-06-05 19:21:32 +00003116- Issue #8271: during the decoding of an invalid UTF-8 byte sequence, only the
3117 start byte and the continuation byte(s) are now considered invalid, instead
3118 of the number of bytes specified by the start byte.
3119 E.g.: '\xf1\x80AB'.decode('utf-8', 'replace') now returns u'\ufffdAB' and
3120 replaces with U+FFFD only the start byte ('\xf1') and the continuation byte
3121 ('\x80') even if '\xf1' is the start byte of a 4-bytes sequence.

3131 objects. (1) The comparison could incorrectly return True in some cases
3132 (2**53+1 == complex(2**53) == 2**53), breaking transivity of equality.
3133 (2) The comparison raised an OverflowError for large integers, leading

Mark Dickinsond2f3e3f2010-05-05 22:23:58 +00003477 (Optimization was unintentionally turned on in gcc --with-pydebug builds in

3499Core and Builtins
3500-----------------
3501
Philip Jenveyaebbaeb2010-04-06 23:24:45 +00003502- Issue #7301: Add environment variable $PYTHONWARNINGS.
3503
Benjamin Peterson3a1dfa22010-04-06 21:50:00 +00003504- Issue #8329: Don't return the same lists from select.select when no fds are
3505 changed.
3506
Georg Brandlfee0f442010-05-22 21:26:21 +00003507- Issue #8259: ``1L << (2**31)`` no longer produces an 'outrageous shift error'
Mark Dickinson82791672010-04-06 16:47:55 +00003508 on 64-bit machines. The shift count for either left or right shift is
3509 permitted to be up to sys.maxsize.
3510
Benjamin Peterson4ceeeb02010-04-03 22:48:51 +00003511- Ensure that tokenization of identifiers is not affected by locale.

Benjamin Peterson1c7c11e2010-04-03 01:28:57 +00003515- Raise a TypeError when trying to delete a T_STRING_INPLACE struct member.
3516
Georg Brandlfee0f442010-05-22 21:26:21 +00003517- Issue #7994: Issue a PendingDeprecationWarning if object.__format__ is called
3518 with a non-empty format string. This is an effort to future-proof user
3519 code. If a derived class does not currently implement __format__ but later
3520 adds its own __format__, it would most likely break user code that had
Antoine Pitrou01a196a2011-01-02 20:05:11 +00003521 supplied a format string. This will be changed to a DeprecationWarning in
Georg Brandlfee0f442010-05-22 21:26:21 +00003522 Python 3.3 and it will be an error in Python 3.4.
Eric Smithd44b2fc2010-04-02 12:30:56 +00003523
Antoine Pitroua57df2c2010-03-31 21:32:15 +00003524- Issue #8268: Old-style classes (not just instances) now support weak

Victor Stinner66644262010-03-10 22:30:19 +00003537- Issue #3137: Don't ignore errors at startup, especially a keyboard interrupt
Georg Brandlba83f822010-03-14 09:50:54 +00003538 (SIGINT). If an error occurs while importing the site module, the error is

3554
Georg Brandlfee0f442010-05-22 21:26:21 +00003555- Issue #8257: The Decimal construct now accepts a float instance directly,
3556 converting that float to a Decimal of equal value:
Mark Dickinson8a950712010-04-03 15:47:46 +00003557
3558 >>> Decimal(1.1)
3559 Decimal('1.100000000000000088817841970012523233890533447265625')
3560
Raymond Hettinger34c35b22010-04-03 10:22:00 +00003561- collections.Counter() now supports a subtract() method.
3562
Georg Brandlfee0f442010-05-22 21:26:21 +00003563- The functools module now has a total_ordering() class decorator to simplify
3564 the specification of rich comparisons.
Raymond Hettingera551f312010-04-04 18:34:45 +00003565
Georg Brandlfee0f442010-05-22 21:26:21 +00003566- The functools module also adds cmp_to_key() as a tool to transition old-style
3567 comparison functions to new-style key-functions.
Raymond Hettingera551f312010-04-04 18:34:45 +00003568
Georg Brandlfee0f442010-05-22 21:26:21 +00003569- Issue #8294: The Fraction constructor now accepts Decimal and float instances
3570 directly.
Mark Dickinson7c63eee2010-04-02 22:27:36 +00003571
Georg Brandlfee0f442010-05-22 21:26:21 +00003572- Issue #7279: Comparisons involving a Decimal signaling NaN now signal
3573 InvalidOperation instead of returning False. (Comparisons involving a quiet
3574 NaN are unchanged.) Also, Decimal quiet NaNs are now hashable; Decimal
3575 signaling NaNs remain unhashable.
Mark Dickinsone096e822010-04-02 10:17:07 +00003576
Georg Brandlfee0f442010-05-22 21:26:21 +00003577- Issue #2531: Comparison operations between floats and Decimal instances now
3578 return a result based on the numeric values of the operands; previously they
3579 returned an arbitrary result based on the relative ordering of id(float) and
3580 id(Decimal).
Mark Dickinson99d80962010-04-02 08:53:22 +00003581
Barry Warsawf7f2d6f2010-03-31 21:07:16 +00003582- Issue #8233: When run as a script, py_compile.py optionally takes a single
Georg Brandlfee0f442010-05-22 21:26:21 +00003583 argument `-` which tells it to read files to compile from stdin. Each line is
3584 read on demand and the named file is compiled immediately. (Original patch by
3585 Piotr Ożarowski).
Barry Warsawf7f2d6f2010-03-31 21:07:16 +00003586
Georg Brandlfee0f442010-05-22 21:26:21 +00003587- Issue #3135: Add ``inspect.getcallargs()``, which binds arguments to a

Florent Xicluna58b65662010-03-30 16:29:03 +00003590- Backwards incompatible change: Unicode codepoints line tabulation (0x0B) and
3591 form feed (0x0C) are now considered linebreaks, as specified in Unicode
Georg Brandlfee0f442010-05-22 21:26:21 +00003592 Standard Annex #14. See issue #7643. http://www.unicode.org/reports/tr14/
Florent Xicluna22b24382010-03-30 08:24:06 +00003593
Georg Brandlfee0f442010-05-22 21:26:21 +00003594- Comparisons using one of <, <=, >, >= between a complex instance and a
3595 Fractions instance now raise TypeError instead of returning True/False. This
3596 makes Fraction <=> complex comparisons consistent with int <=> complex, float
3597 <=> complex, and complex <=> complex comparisons.
Mark Dickinson9588d992010-03-27 11:14:37 +00003598

Antoine Pitrou513d9ae2010-03-22 19:59:46 +00003608- Issue #7512: shutil.copystat() could raise an OSError when the filesystem
Georg Brandlfee0f442010-05-22 21:26:21 +00003609 didn't support chflags() (for example ZFS under FreeBSD). The error is now
3610 silenced.

3702 integer format code (one of 'bBhHiIlLqQ'), struct.pack attempts to use the
3703 argument's __int__ method to convert to an integer before packing. It also
Georg Brandlfee0f442010-05-22 21:26:21 +00003704 produces a DeprecationWarning in this case. (In Python 2.6, the behaviour was
3705 inconsistent: __int__ was used for some integer codes but not for others, and
3706 the set of integer codes for which it was used differed between native packing
3707 and standard packing.)

Georg Brandlba83f822010-03-14 09:50:54 +00003919- Issue #7712: test_support gained a new ``temp_cwd`` context manager which is
3920 now also used by regrtest to run all the tests in a temporary directory. The
3921 original CWD is saved in ``test.test_support.SAVEDCWD``. Thanks to Florent
3922 Xicluna who helped with the patch.

3939 and read operations on write-only file objects. On Windows, the system C
Georg Brandlba83f822010-03-14 09:50:54 +00003940 library would return a bogus result; on Solaris, it was possible to crash the

Georg Brandlba83f822010-03-14 09:50:54 +00003959- Issue #7561: Operations on empty bytearrays (such as ``int(bytearray())``)
3960 could crash in many places because of the ``PyByteArray_AS_STRING()`` macro
3961 returning NULL. The macro now returns a statically allocated empty string
3962 instead.

3972 strings,
3973 (2) a crash in dtoa.c that occurred in debug builds when parsing certain long
3974 numeric strings corresponding to subnormal values,
3975 (3) a memory leak for some values large enough to cause overflow, and
3976 (4) a number of flaws that could lead to incorrectly rounded results.

Antoine Pitroud840e512010-02-04 20:20:18 +00004007- Issue #4772: Raise a ValueError when an unknown Bluetooth protocol is
Georg Brandlba83f822010-03-14 09:50:54 +00004008 specified, rather than fall through to AF_PACKET (in the ``socket`` module).
Antoine Pitroud840e512010-02-04 20:20:18 +00004009 Also, raise ValueError rather than TypeError when an unknown TIPC address
4010 type is specified. Patch by Brian Curtin.

Antoine Pitrouf3fa0742010-01-31 22:26:04 +00004014- Issue #6939: Fix file I/O objects in the `io` module to keep the original
Georg Brandlba83f822010-03-14 09:50:54 +00004015 file position when calling `truncate()`. It would previously change the file
4016 position to the given argument, which goes against the tradition of
Antoine Pitrouf3fa0742010-01-31 22:26:04 +00004017 ftruncate() and other truncation APIs. Patch by Pascal Chambon.
4018
Georg Brandlba83f822010-03-14 09:50:54 +00004019- Issue #7610: Reworked implementation of the internal ``zipfile.ZipExtFile``
4020 class used to represent files stored inside an archive. The new
4021 implementation is significantly faster and can be wrapped in a
4022 ``io.BufferedReader`` object for more speedups. It also solves an issue
4023 where interleaved calls to ``read()`` and ``readline()`` give wrong results.
4024 Patch by Nir Aides.

Benjamin Petersona43f34c2010-01-25 03:31:13 +00004033
Georg Brandlba83f822010-03-14 09:50:54 +00004034- Issue #7748: Since unicode values are supported for some metadata options in
4035 Distutils, the DistributionMetadata get_* methods will now return an utf-8
4036 encoded string for them. This ensures that the upload and register commands
4037 send the correct values to PyPI without any error.

Georg Brandlba83f822010-03-14 09:50:54 +00004114- The ``__complex__()`` method is now looked up on the class of instances to

4122 These functions and methods now raise TypeError instead. The majority of the
4123 effects of this change are in the extension modules, but some core functions
4124 and methods are affected: notably the 'chr', 'range' and 'xrange' builtins,
4125 and many unicode/str methods.

4149
Georg Brandlba83f822010-03-14 09:50:54 +00004150 These executables now work properly with the arch(1) command: ``arch -ppc
4151 python`` will start a universal binary version of python in PPC mode (unlike

Georg Brandlba83f822010-03-14 09:50:54 +00004308- Issue #7117: ``repr(x)`` for a float x returns a result based on the shortest
4309 decimal string that's guaranteed to round back to x under correct rounding
4310 (with round-half-to-even rounding mode). Previously it gave a string based on
4311 rounding x to 17 decimal digits. repr(x) for a complex number behaves
4312 similarly. On platforms where the correctly-rounded strtod and dtoa code is
4313 not supported (see below), repr is unchanged.
Mark Dickinsonb678de82009-11-19 18:41:49 +00004314
Georg Brandlba83f822010-03-14 09:50:54 +00004315- Issue #7117: On almost all platforms: float-to-string and string-to-float
4316 conversions within Python are now correctly rounded. Places these conversions
4317 occur include: str for floats and complex numbers; the float and complex
4318 constructors; old-style and new-style numeric formatting; serialization and
4319 deserialization of floats and complex numbers using marshal, pickle and json;
4320 parsing of float and imaginary literals in Python code; Decimal-to-float
4321 conversion.
Mark Dickinsonb678de82009-11-19 18:41:49 +00004322
Georg Brandlba83f822010-03-14 09:50:54 +00004323 The conversions use a Python-adapted version of David Gay's well-known dtoa.c,
4324 providing correctly-rounded strtod and dtoa C functions. This code is
4325 supported on Windows, and on Unix-like platforms using gcc, icc or suncc as
4326 the C compiler. There may be a small number of platforms on which correct
4327 operation of this code cannot be guaranteed, so the code is not used: notably,
4328 this applies to platforms where the C double format is not IEEE 754 binary64,
4329 and to platforms on x86 hardware where the x87 FPU is set to 64-bit precision
4330 and Python's configure script is unable to determine how to change the FPU
4331 precision. On these platforms conversions use the platform strtod and dtoa,
4332 as before.

Georg Brandlba83f822010-03-14 09:50:54 +00004334- Issue #7117: Backport round implementation from Python 3.x. ``round()`` now
4335 uses the correctly-rounded string <-> float conversions described above (when
4336 available), and so produces correctly rounded results that will display nicely
4337 under the float repr. There are two related small changes: (1) round now
4338 accepts any class with an ``__index__()`` method for its second argument (but
4339 no longer accepts floats for the second argument), and (2) an excessively
4340 large second integer argument (e.g., ``round(1.234, 10**100)``) no longer
4341 raises an exception.

Georg Brandlba83f822010-03-14 09:50:54 +00004488- Issue #5920: For ``float.__format__()``, change the behavior with the empty
4489 presentation type (that is, not one of 'e', 'f', 'g', or 'n') to be like 'g'
4490 but with at least one decimal point and with a default precision
4491 of 12. Previously, the behavior the same but with a default precision of 6.
4492 This more closely matches ``str()``, and reduces surprises when adding

4494 complex.__format__ in the same way.

Georg Brandlba83f822010-03-14 09:50:54 +00004634- Issue #1180193: When importing a module from a .pyc (or .pyo) file with an
4635 existing .py counterpart, override the co_filename attributes of all code

4691
Georg Brandlba83f822010-03-14 09:50:54 +00004692- Issue #4233: Changed semantic of ``_fileio.FileIO``'s ``close()`` method on
4693 file objects with closefd=False. The file descriptor is still kept open but
4694 the file object behaves like a closed file. The ``FileIO`` object also got a

Georg Brandlba83f822010-03-14 09:50:54 +00004718- On windows, ``os.chdir()`` given unicode was not working if

4720 this code path is really executed because I cannot move to such directory on
4721 win2k)

4724 element is temporarily replaced with an equivalent frozenset. But the
4725 eventual KeyError would always report the empty ``frozenset()`` as the missing

4747 PyUnicode_DecodeUTF8() once, remember the result and output it in a second
4748 step. This avoids problems with counting UTF-8 bytes that ignores the effect
4749 of using the replace error handler in PyUnicode_DecodeUTF8().
4750
Walter Dörwald726ba8e2009-05-06 14:32:35 +00004751- Issue #3739: The unicode-internal encoder now reports the number of characters

4753
Georg Brandlba83f822010-03-14 09:50:54 +00004754- Issue #2422: When compiled with the ``--with-valgrind`` option, the pymalloc

4756 gives improved memory leak detection when running under Valgrind, while taking
4757 advantage of pymalloc at other times.

6003 Lib/lib-tk/test/test_tkinter/test_loadtk. With this, these tests demonstrate
Georg Brandlba83f822010-03-14 09:50:54 +00006004 the same behaviour as test_ttkguionly (and now also test_tk) which is to skip
6005 the tests if DISPLAY is defined but can't be used.

6011 import both normal and optimised versions of modules. test_heapq and

Martin v. Löwis9fa5a282008-09-11 06:53:30 +00006125- Issue #3642: Suppress warning in obmalloc when size_t is larger than uint.
6126
Amaury Forgeot d'Arc05e34492008-09-10 22:04:45 +00006127- Issue #3743: In a few places, PY_FORMAT_SIZE_T was incorrectly used with
6128 PyString_FromFormat or PyErr_Format to display size_t values. The macro
6129 PY_FORMAT_SIZE_T is designed to select the correct format for the OS
6130 ``printf`` function, whereas PyString_FromFormat has an independent
6131 implementation and uses "%zd" on all platforms for size_t values.
6132 This makes a difference on win64, where ``printf`` needs "%Id" to display
6133 64bit values.

Benjamin Peterson97179b02008-09-09 20:55:01 +00006135- Issue #3634: _weakref.ref(Exception).__init__() gave invalid return value on

6139 object; previously an int would be returned for small values. the __long__
6140 method is allowed to return either an int or a long, but the behaviour of
6141 float objects should not change to respect backward compatibility.

Amaury Forgeot d'Arc3571fbf2008-09-01 19:52:00 +00006143- Issue #3751: str.rpartition would perform a left-partition when called with

Antoine Pitroud4ae97b2008-08-29 18:39:48 +00006150 was correctly parsed but parsing of subsequent arguments failed.
6151
Vinay Sajip35e3b032008-09-01 14:33:59 +00006152- Issue #2534: speed up isinstance() and issubclass() by 50-70%, so as to
Antoine Pitrou0668c622008-08-26 22:42:08 +00006153 match Python 2.5 speed despite the __instancecheck__ / __subclasscheck__
6154 mechanism. In the process, fix a bug where isinstance() and issubclass(),
6155 when given a tuple of classes as second argument, were looking up
6156 __instancecheck__ / __subclasscheck__ on the tuple rather than on each
6157 type object.

Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00006296What's New in Python 2.6 beta 3?
6297================================
6298
Barry Warsaw07a4a382008-08-21 01:15:08 +00006299*Release date: 20-Aug-2008*
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00006300
6301Core and Builtins
6302-----------------
6303
Guido van Rossumf8402962008-08-20 15:01:50 +00006304- Issue #1878: Remove Py_TPFLAGS_HAVE_VERSION_TAG from
6305 Py_TPFLAGS_DEFAULT when not building the core. This means 3rd party
6306 extensions do not automatically benefit from the class attribute
6307 cache; they will have to explicitly add Py_TPFLAGS_HAVE_VERSION_TAG
6308 to their tp_flags field if they care. This is a backwards
6309 compatibility feature; in 3.0, all types will use the cache by
6310 default.
6311
Benjamin Petersonf647dc12008-08-20 01:27:30 +00006312- Keyword arguments can now follow starred arguments. (``f(a, *args,
6313 keyword=23)`` is now valid syntax.)
6314
Thomas Heller0ad5ae02008-08-19 19:25:04 +00006315- ctypes function pointers that are COM methods have a boolean True
6316 value again.
6317
Martin v. Löwisf91d46a2008-08-12 14:49:50 +00006318- Issue #3139: Make buffer-interface thread-safe wrt. PyArg_ParseTuple,
6319 by denying s# to parse objects that have a releasebuffer procedure,
6320 and introducing s*.
6321
Georg Brandl1e13ea92008-08-11 09:07:59 +00006322- Issue #3537: Fix an assertion failure when an empty but presized dict
6323 object was stored in the freelist.
6324
Mark Dickinsonb6467572008-08-04 21:30:09 +00006325- Issue #1481296: Make long(float('nan')) and int(float('nan')) raise
6326 ValueError consistently across platforms.
6327
Amaury Forgeot d'Arc39fd6722008-07-31 21:28:03 +00006328- Issue #3479: On platforms where sizeof(int) is smaller than sizeof(long)
6329 (64bit Unix, for example), unichr() would truncate its argument and return
6330 u'\x00' for unichr(2**32). Now it properly raises an OverflowError.
6331
Neal Norwitze7d8be82008-07-31 17:17:14 +00006332- Apply security patches from Apple.
6333
Amaury Forgeot d'Arc246daed2008-07-31 00:42:16 +00006334- Issue #2542: Now that issubclass() may call arbitrary code, ensure that
6335 PyErr_ExceptionMatches returns 0 when an exception occurs there.
6336
Antoine Pitrou92f82162008-07-25 22:22:08 +00006337- Issue #1819: function calls with several named parameters are now on
6338 average 35% faster (as measured by pybench).
6339
Amaury Forgeot d'Arce4921fe2008-07-21 22:00:38 +00006340- Issue #2378: An unexpected UnboundLocalError or NameError could appear when
6341 the python debugger steps into a class statement: the free variables (local
6342 variables defined in an outer scope) would be deleted from the outer scope.
6343
Gregory P. Smith0470bab2008-07-22 04:46:32 +00006344- Issue #2620: Overflow checking when allocating or reallocating memory
6345 was not always being done properly in some python types and extension
6346 modules. PyMem_MALLOC, PyMem_REALLOC, PyMem_NEW and PyMem_RESIZE have
6347 all been updated to perform better checks and places in the code that
6348 would previously leak memory on the error path when such an allocation
6349 failed have been fixed.
6350
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00006351Library
6352-------
6353
Hirokazu Yamamoto838c79f2008-08-20 13:14:07 +00006354- Issue #3612: Added some missing basic types in ctypes.wintypes.
6355
Benjamin Petersone977ad42008-08-20 01:42:01 +00006356- The methods ``is_in_tuple()``, ``is_vararg()``, and ``is_keywordarg()`` of
6357 symtable.Symbol have been deprecated for removal in 3.0 and the next release.
6358
Amaury Forgeot d'Arc351ffb82008-08-18 19:23:47 +00006359- Issue #2234: distutils failed for some versions of the cygwin compiler. The
6360 version reported by these tools does not necessarily follow the python
6361 version numbering scheme, so the module is less strict when parsing it.
6362
Nick Coghlanf70385a2008-08-18 12:42:46 +00006363- Issue #2235: Added Py3k warnings for types which will become unhashable
6364 under the stricter __hash__ inheritance rules in 3.0. Several types
6365 which did not meet the rules for hash invariants and were already
6366 unhashable in 3.0 have now been explicitly flagged as unhashable in
6367 2.6 as well (collections.Mapping, collections.Set, unittest.TestSuite,
6368 xml.dom.minidom.NamedNodeMap, numbers.Number, UserList.UserList)
6369
Brett Cannon88f801d2008-08-18 00:46:22 +00006370- Update __all__ for cookielib, csv, os, urllib2, and weakref to include things
6371 imported into the module but exposed as part of the module's API.
6372
Brett Cannon7b96f072008-08-18 00:41:11 +00006373- Remove an unneeded import of abc.ABCMeta from 'inspect'.
6374
Brett Cannon46225e72008-08-18 00:36:52 +00006375- Remove unneeded imports of 'sys' and 'warnings' from 'io'.
6376
Brett Cannon25c9d6a2008-08-17 22:10:11 +00006377- Remove unneeded imports of 'warnings' from shelve, filecmp, and dummy_thread.
6378
Hirokazu Yamamoto41a81eb2008-08-17 13:10:46 +00006379- Issue #3575: Incremental decoder's decode function now takes bytearray
6380 by using 's*' instead of 't#'.
6381
Mark Dickinson3e4caeb2009-02-21 20:27:01 +00006382- Issue #2222: Fixed reference leak when occurred os.rename()
Hirokazu Yamamoto7f30a682008-08-17 09:46:56 +00006383 fails unicode conversion on 2nd parameter. (windows only)
6384
Georg Brandl222e2082010-08-01 22:27:39 +00006385- Issue #2464: urllib2 now supports a malformation in the URL received
Facundo Batista94f243a2008-08-17 03:38:39 +00006386 in a redirect.
6387
Brett Cannonabe423e2008-08-16 21:47:07 +00006388- Silence the DeprecationWarning raised when importing mimetools in
Brett Cannon721b1452008-08-16 22:00:27 +00006389 BaseHTTPServer, cgi (and rfc822), httplib.
Brett Cannonabe423e2008-08-16 21:47:07 +00006390
Facundo Batistaeb90b782008-08-16 14:44:07 +00006391- Issue #2776: fixed small issue when handling an URL with double slash
6392 after a 302 response in the case of not going through a proxy.
6393
Antoine Pitroub90a8be2008-08-15 21:03:21 +00006394- Issue #2676: in the email package, content-type parsing was hanging on
6395 pathological input because of quadratic or exponential behaviour of a
6396 regular expression.
6397
Antoine Pitrou11ec65d2008-08-14 21:04:30 +00006398- Issue #3476: binary buffered reading through the new "io" library is now
6399 thread-safe.
6400
Brett Cannonbf3157b2008-08-14 05:00:03 +00006401- Silence the DeprecationWarning of rfc822 when it is imported by mimetools
6402 since mimetools itself is deprecated. Because modules are cached, all
6403 subsequent imports of rfc822 will not raise a visible DeprecationWarning.
6404
Antoine Pitrou9fcd4b32008-08-11 17:21:36 +00006405- Issue #3134: shutil referenced undefined WindowsError symbol.
6406
Robert Schuppenies14646332008-08-10 11:01:53 +00006407- Issue #1342811: Fix leak in Tkinter.Menu.delete. Commands associated to
6408 menu entries were not deleted.
6409
Brett Cannon83e81842008-08-09 23:30:55 +00006410- Copied the implementation of reduce() to _functools.reduce() to have a
6411 version that did not raise a DeprecationWarning under -3.
6412
Antoine Pitrou76b8bee2008-08-09 17:27:23 +00006413- Issue #3205: When iterating over a BZ2File fails allocating memory, raise
6414 a MemoryError rather than silently stop the iteration.
6415
Guido van Rossum59ce9012008-08-09 14:55:34 +00006416- Issue #3487: sre "bytecode" validator. Passing invalid "re-bytecode"
6417 to _sre.compile() will now be rejected. This should not affect anybody
6418 since the re.compile() function never generates invalid re-bytecode.
6419
Skip Montanaroa032bf42008-08-08 22:52:51 +00006420- Issue #3436: Make csv.DictReader's fieldnames attribute a property so that
6421 upon first access it can be automatically initialized from the csv file if
6422 it wasn't initialized during instantiation.
6423
Brett Cannon3aa2a492008-08-06 22:28:09 +00006424- Issue #2338: Create imp.reload() to help with transitioning to Python 3.0 as
6425 the reload() built-in has been removed.
6426
Brett Cannon7e30b672008-08-04 21:52:25 +00006427- Changed code in the following modules/packages to remove warnings raised
Brett Cannonc1b76e42008-08-09 23:06:16 +00006428 while running under the ``-3`` flag: aifc, asynchat, asyncore, bdb, bsddb,

6430 filecmp, fileinput, inspect, logging, modulefinder, pdb, pickle, profile,
6431 pstats, pydoc, re, rlcompleter, SimpleXMLRPCServer, shelve, socket,
6432 subprocess, sqlite3, tarfile, Tkinter, test.test_support, textwrap,
6433 threading, tokenize, traceback, urlparse, wsgiref, xml, xmlrpclib.
Brett Cannon7e30b672008-08-04 21:52:25 +00006434
Lars Gustäbel727bd0b2008-08-02 11:26:39 +00006435- Issue #3039: Fix tarfile.TarFileCompat.writestr() which always
6436 raised an AttributeError.
6437
Benjamin Peterson01a24322008-07-28 23:35:27 +00006438- Issue #2523: Fix quadratic behaviour when read()ing a binary file without
Antoine Pitroude781a42008-08-09 12:43:23 +00006439 asking for a specific length. This problem only affected files opened
6440 using the new "io" module, not the built-in open() function.
Benjamin Peterson01a24322008-07-28 23:35:27 +00006441
Mark Dickinsonfe84cce2008-07-27 06:39:07 +00006442- Issue #3449: Update decimal module to use most recent specification
6443 (v. 1.68) and tests (v. 2.58) from IBM.
6444
Georg Brandl222e2082010-08-01 22:27:39 +00006445- Issue #3437: Bug fix in robotparser parsing of Allow: lines.
Skip Montanarof9ac43f2008-07-27 00:50:41 +00006446
Georg Brandl222e2082010-08-01 22:27:39 +00006447- Issue #1592: Improve error reporting when operations are attempted
Raymond Hettinger8c664e82008-07-25 18:43:33 +00006448 on a closed shelf.
6449
Georg Brandlf9efabb2008-07-23 15:16:45 +00006450- Deprecate the "ast" parser function aliases.
6451
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00006452- Issue #3120: On 64-bit Windows the subprocess module was truncating handles.
6453
6454- Issue #3303: Fix a crash in locale.strcoll() when calling it with
6455 invalid arguments.
6456
6457- Issue #3302: Fix several crashes when calling locale's gettext functions
6458 with None arguments.
6459
6460- Issue #3389: Allow resolving dotted names for handlers in logging
6461 configuration files.
6462
6463- Deprecate the sunaudio module for removal in Python 3.0.
6464
Antoine Pitrou5fdfa3e2008-07-25 19:42:26 +00006465- Issue #3394: zipfile.writestr sets external attributes when passed a
6466 file name rather than a ZipInfo instance, so files are extracted with
6467 mode 0600 rather than 000 under Unix.
6468
Gregory P. Smitha36f8fe2008-08-04 00:13:29 +00006469- Issue #1857: subprocess.Popen.poll gained an additional _deadstate keyword
6470 argument in python 2.5, this broke code that subclassed Popen to include its
6471 own poll method. Fixed my moving _deadstate to an _internal_poll method.

Nick Coghlan6e8fef02008-08-18 13:14:22 +00006481- Issue #2235: the C API function PyObject_HashNotImplemented and its
6482 interaction with the tp_hash slot (added in 2.6b2) are now documented
6483
Nick Coghlan2a0c2b12008-08-04 12:47:17 +00006484- Issue #643841: The language reference now provides more detailed
6485 coverage of the lookup process for special methods. The disclaimers
6486 regarding lack of coverage of new-style classes have also been
6487 removed, since the coverage is now fairly reasonable.

6491================================
6492
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00006493*Release date: 17-Jul-2008*
6494
Raymond Hettingere3ae6552008-06-20 04:18:15 +00006495Core and Builtins
6496-----------------
6497
Georg Brandl3e483f62008-07-16 22:57:41 +00006498- Issue #3156: Fix inconsistent behavior of the bytearray type: all
6499 its methods now allow for items objects that can be converted to
6500 an integer using operator.index().
6501
Mark Dickinson64b7e502008-07-16 09:40:03 +00006502- Issue #3360: Fix incorrect parsing of '020000000000.0', which
6503 produced a ValueError instead of giving the correct float.
6504
Eric Smitha5fa5a22008-07-16 00:11:49 +00006505- Issue #3083: Add alternate (#) formatting for bin, oct, hex output
6506 for str.format(). This adds the prefix 0b, 0o, or 0x, respectively.
6507
Mark Dickinson7103aa42008-07-15 19:08:33 +00006508- Issue #3008: the float type has a new instance method 'float.hex'
6509 and a new class method 'float.fromhex' to convert floating-point
6510 numbers to and from hexadecimal strings, respectively.
6511
Nick Coghlan6d6bd442008-07-15 15:40:22 +00006512- Issue #2235: __hash__ is once again inherited by default. To allow
6513 collections.Hashable to remain meaningful in the presence of the
6514 default hash implementation (object.__hash__), it is now possible
6515 to explicit block inheritance of hash by setting __hash__=None at
6516 the Python level, or tp_hash=PyObject_HashNotImplemented at the C
6517 level.
6518
Nick Coghlanb028f502008-07-13 14:52:36 +00006519- Issue #3221: Issue a RuntimeWarning instead of raising SystemError if
6520 the parent module cannot be found while performing an absolute import.
6521 This means that an incorrectly defined __package__ attribute will
6522 now only prevent relative imports in that module rather than causing
6523 all imports from that module to fail.
6524
Nick Coghlan14ff9942008-07-08 14:21:42 +00006525- Issue #2517: Allow unicode messages in Exceptions again by correctly
6526 bypassing the instance dictionary when looking up __unicode__ on
6527 new-style classes.
6528
Amaury Forgeot d'Arcbdd941f2008-07-01 20:38:04 +00006529- Issue #3242: Fix a crash inside the print statement, if sys.stdout is
6530 set to a custom object whose write() method happens to install
6531 another file in sys.stdout.
6532
Amaury Forgeot d'Arc1f40c8a2008-06-30 22:42:40 +00006533- Issue #3088: Corrected a race condition in classes derived from
6534 threading.local: the first member set by a thread could be saved in
6535 another thread's dictionary.
6536
Mark Dickinson1ec2fcd2008-06-20 14:53:43 +00006537- Issue #3004: Minor change to slice.indices(): the start and stop
6538 arguments are now treated identically, making the behaviour easier
6539 to describe and understand. For example, slice(None, -10,
6540 1).indices(9) now returns (0, 0, 1) instead of (0, -1, 1), and
6541 slice(None, 10, -1).indices(10) returns (9, 9, -1) instead of (9,
6542 10, -1).
6543
Georg Brandl278fc502008-07-19 12:46:12 +00006544- Issue #3219: Calling a function with repeated keyword arguments,
6545 f(a=2, a=23), would not cause a syntax error. This was a regression
6546 from 2.4 caused by the switch to the new compiler.

6549 other freelists. Changes their CompactFreeList apis into
6550 ClearFreeList apis and calls them via gc.collect().

6557 error when they failed.
6558
Martin v. Löwisaabf4042008-08-02 07:20:25 +00006559- Issue #799428: Fix Tkinter.Misc._nametowidget to unwrap Tcl command objects.

Georg Brandl5cc774e2008-06-11 20:28:06 +00006996 PPC64 and x86_64 support in one binary).
Ronald Oussoren5640ce22008-06-05 12:58:24 +00006997
6998 This is controlled by the configure argument ``--with-universal-archs``:
6999
7000 - ``--with-universal-archs=all``: install 4-way universal
7001
7002 - ``--with-universal-archs=32-bit``: install 2-way universal, 32-bit (the default)
7003
7004 - ``--with-universal-archs=64-bit``: install 2-way universal, 64-bit
7005
7006 This option should be used in combination with ``--enable-universalsdk=``.

Georg Brandl3ee81df2008-05-17 18:14:43 +00007058- Issue #1631171: Re-implement the 'warnings' module in C (the
7059 original Python code has been kept as backup). This will allow for
7060 using the 'warning's machinery in such places as the parser where
7061 use of pure Python code is not possible. Both the ``showarning()``
7062 and ``formatwarning()`` gain an optional 'line' argument which is
7063 not called by default for backwards-compatibility reasons. Setting
7064 ``warnings.showwarning()`` to an implementation that lacks support
7065 for the ``line`` argument will raise a DeprecationWarning.

7113 file.close() is called while an object is in use by another thread
7114 an IOError exception will be raised and the file will not be closed.

Georg Brandl3ee81df2008-05-17 18:14:43 +00007120- Issue #2385: distutils.core.run_script() makes __file__ available,
7121 so the controlled environment will more closely mirror the typical
7122 script environment. This supports setup.py scripts that refer to
7123 data files.

Georg Brandl3ee81df2008-05-17 18:14:43 +00007128- Issue #2550: The approach used by client/server code for obtaining
7129 ports to listen on in network-oriented tests has been refined in an
7130 effort to facilitate running multiple instances of the entire
7131 regression test suite in parallel without issue.
7132 test_support.bind_port() has been fixed such that it will always
7133 return a unique port -- which wasn't always the case with the
7134 previous implementation, especially if socket options had been set
7135 that affected address reuse (i.e. SO_REUSEADDR, SO_REUSEPORT). The
7136 new implementation of bind_port() will actually raise an exception
7137 if it is passed an AF_INET/SOCK_STREAM socket with either the
7138 SO_REUSEADDR or SO_REUSEPORT socket option set. Furthermore, if
7139 available, bind_port() will set the SO_EXCLUSIVEADDRUSE option on
7140 the socket it's been passed. This currently only applies to
7141 Windows. This option prevents any other sockets from binding to the
7142 host/port we've bound to, thus removing the possibility of the
7143 'non-deterministic' behaviour, as Microsoft puts it, that occurs
7144 when a second SOCK_STREAM socket binds and accepts to a host/port
7145 that's already been bound by another socket. The optional preferred
7146 port parameter to bind_port() has been removed. Under no
7147 circumstances should tests be hard coding ports!
7148
7149 test_support.find_unused_port() has also been introduced, which will
7150 pass a temporary socket object to bind_port() in order to obtain an
7151 unused port. The temporary socket object is then closed and
7152 deleted, and the port is returned. This method should only be used
7153 for obtaining an unused port in order to pass to an external program
7154 (i.e. the -accept [port] argument to openssl's s_server mode) or as
7155 a parameter to a server-oriented class that doesn't give you direct
7156 access to the underlying socket used.
7157
7158 Finally, test_support.HOST has been introduced, which should be used
7159 for the host argument of any relevant socket calls (i.e. bind and
7160 connect).
Trent Nelsone41b0062008-04-08 23:47:30 +00007161
7162 The following tests were updated to following the new conventions:
Georg Brandl3ee81df2008-05-17 18:14:43 +00007163 test_socket, test_smtplib, test_asyncore, test_ssl, test_httplib,
Trent Nelsone41b0062008-04-08 23:47:30 +00007164 test_poplib, test_ftplib, test_telnetlib, test_socketserver,
7165 test_asynchat and test_socket_ssl.
7166
Georg Brandl3ee81df2008-05-17 18:14:43 +00007167 It is now possible for multiple instances of the regression test
7168 suite to run in parallel without issue.

7436
Fred Drakea8ee94b2008-03-01 02:45:07 +00007437- Issue #2051: pyc and pyo files are no longer created with permission
Barry Warsaw52973612008-03-01 02:23:38 +00007438 644. The mode is now inherited from the py file.

Facundo Batistafc2d0102008-02-23 12:01:13 +00007446
Eric Smitha73fbe72008-02-23 03:09:44 +00007447- Added the future_builtins module, which contains hex() and oct().
7448 These are the PEP 3127 version of these functions, designed to be
7449 compatible with the hex() and oct() builtins from Python 3.0. They
7450 differ slightly in their output formats from the existing, unchanged
7451 Python 2.6 builtins. The expected usage of the future_builtins
7452 module is:
7453 from future_builtins import hex, oct
7454
Eric Smith7ef40bf2008-02-20 23:34:22 +00007455- Issue #1600: Modifed PyOS_ascii_formatd to use at most 2 digit
7456 exponents for exponents with absolute value < 100. Follows C99
7457 standard. This is a change on Windows, which would use 3 digits.
7458 Also, added 'n' to the formats that PyOS_ascii_formatd understands,
7459 so that any alterations it does to the resulting string will be
7460 available in stringlib/formatter.h (for float.__format__).
7461
Eric Smith5a3c1352008-02-19 13:21:56 +00007462- Implemented PEP 3101, Advanced String Formatting. This adds a new
7463 builtin format(); a format() method for str and unicode; a
7464 __format__() method to object, str, unicode, int, long, float, and
7465 datetime; the class string.Formatter; and the C API
7466 PyObject_Format().
7467
Georg Brandl3ee81df2008-05-17 18:14:43 +00007468- Fixed several potential crashes, all caused by specially crafted
7469 __del__ methods exploiting objects in temporarily inconsistent
7470 state.
Amaury Forgeot d'Arc632fad32008-02-16 20:55:24 +00007471
Vinay Sajipb7edfc42008-04-02 21:10:23 +00007472- Issue #2115: Important speedup in setting __slot__ attributes. Also
Georg Brandl3ee81df2008-05-17 18:14:43 +00007473 prevent a possible crash: an Abstract Base Class would try to access
7474 a slot on a registered virtual subclass.
Amaury Forgeot d'Arc60d6c7f2008-02-15 21:22:45 +00007475
Georg Brandl3ee81df2008-05-17 18:14:43 +00007476- Fixed repr() and str() of complex numbers with infinity or nan as
7477 real or imaginary part.
Christian Heimes2f0da532008-02-15 06:57:08 +00007478
Georg Brandl3ee81df2008-05-17 18:14:43 +00007479- Clear all free lists during a gc.collect() of the highest generation
7480 in order to allow pymalloc to free more arenas. Python may give back
7481 memory to the OS earlier.
Christian Heimes3b718a72008-02-14 12:47:33 +00007482
Georg Brandl3ee81df2008-05-17 18:14:43 +00007483- Issue #2045: Fix an infinite recursion triggered when printing a
7484 subclass of collections.defaultdict, if its default_factory is set
7485 to a bound method.
Amaury Forgeot d'Arcb01aa432008-02-08 00:56:02 +00007486
Christian Heimesf75dbef2008-02-08 00:11:31 +00007487- Fixed a minor memory leak in dictobject.c. The content of the free
7488 list was not freed on interpreter shutdown.
7489
Georg Brandl21e99f42010-03-07 15:23:59 +00007490- Limit free list of method and built-in function objects to 256
Georg Brandl3ee81df2008-05-17 18:14:43 +00007491 entries each.
Christian Heimes6075a822008-02-06 12:44:34 +00007492
Georg Brandl3ee81df2008-05-17 18:14:43 +00007493- Patch #1953: Added ``sys._compact_freelists()`` and the C API
7494 functions ``PyInt_CompactFreeList`` and ``PyFloat_CompactFreeList``
Christian Heimes422051a2008-02-04 18:00:12 +00007495 to compact the internal free lists of pre-allocted ints and floats.
7496
Georg Brandl3ee81df2008-05-17 18:14:43 +00007497- Issue #1983: Fixed return type of fork(), fork1() and forkpty()
7498 calls. Python expected the return type int but the fork familie
7499 returns pi_t.
Christian Heimes951cc0f2008-01-31 23:08:23 +00007500
Georg Brandl3ee81df2008-05-17 18:14:43 +00007501- Issue #1678380: Fix a bug that identifies 0j and -0j when they
7502 appear in the same code unit.

7511 the internal lookup cache for ref leak tests.
Christian Heimes908caac2008-01-27 23:34:59 +00007512
Georg Brandl3ee81df2008-05-17 18:14:43 +00007513- Patch #1473257: generator objects gain a gi_code attribute. This is
7514 the same object as the func_code attribute of the function that
7515 produced the generator.
Georg Brandl0cdf9a32008-01-26 14:14:20 +00007516
Georg Brandl3ee81df2008-05-17 18:14:43 +00007517- Issue #1920: "while 0" statements were completely removed by the
7518 compiler, even in the presence of an "else" clause, which is
7519 supposed to be run when the condition is false. Now the compiler
7520 correctly emits bytecode for the "else" suite.
Amaury Forgeot d'Arc31eaafe2008-01-24 22:59:25 +00007521
Guido van Rossumeead05f2008-01-24 18:21:02 +00007522- A few crashers fixed: weakref_in_del.py (issue #1377858);
7523 loosing_dict_ref.py (issue #1303614, test67.py);
7524 borrowed_ref_[34].py (not in tracker).
7525
Vinay Sajipd7cf32e2008-01-24 12:43:33 +00007526- Issue #1069410: The "can't load dll" message box on Windows is
Christian Heimesb2302ba2008-01-23 17:15:06 +00007527 suppressed while an extension is loaded by calling SetErrorMode in
7528 dynload_win.c. The error is still reported properly.
7529
Georg Brandl3ee81df2008-05-17 18:14:43 +00007530- Issue #1915: Python compiles with --enable-unicode=no again. However
Christian Heimes082c9b02008-01-23 14:20:50 +00007531 several extension methods and modules do not work without unicode
7532 support.
7533
Georg Brandl26543b12008-01-21 18:36:51 +00007534- Issue #1882: when compiling code from a string, encoding cookies in the
7535 second line of code were not always recognized correctly.
7536
Georg Brandl14404b62008-01-19 19:27:05 +00007537- Issue #1679: "0x" was taken as a valid integer literal.
7538
Georg Brandl6caad7d2008-01-26 14:19:22 +00007539- Issue #1865: ``bytes`` as an alias for ``str`` and b"" as an alias "" were
Christian Heimes288e89a2008-01-18 18:24:07 +00007540 added.
7541
Christian Heimesc94e2b52008-01-14 04:13:37 +00007542- sys.float_info / PyFloat_GetInfo: The floating point information
7543 object was converted from a dict to a specialized structseq object.
7544
Georg Brandl3ee81df2008-05-17 18:14:43 +00007545- Patch #1816: Added sys.flags structseq. It exposes the status of
7546 most command line arguments and PYTHON* environment variables.
Christian Heimesf31b69f2008-01-14 03:42:48 +00007547
Georg Brandl3ee81df2008-05-17 18:14:43 +00007548- Objects/structseq.c: Implemented new structseq representation. The
7549 patch makes structseqs (e.g. the return value of os.stat) more
7550 readable.
Christian Heimes9c201962008-01-14 03:33:52 +00007551
Georg Brandl3ee81df2008-05-17 18:14:43 +00007552- Patch #1700288: added a type attribute cache that caches method

Georg Brandl3ee81df2008-05-17 18:14:43 +00007564- Improve some exception messages when Windows fails to load an
7565 extension module. Now we get for example '%1 is not a valid Win32
7566 application' instead of 'error code 193'.

Georg Brandl3ee81df2008-05-17 18:14:43 +00007574 and INF. float("nan"), float("inf") and float("-inf") now work on
7575 every platform with IEEE 754 semantics.
Christian Heimes0a8143f2007-12-18 23:22:54 +00007576
Georg Brandl3ee81df2008-05-17 18:14:43 +00007577- Compiler now generates simpler and faster code for dictionary
7578 literals. The oparg for BUILD_MAP now indicates an estimated
7579 dictionary size. There is a new opcode, STORE_MAP, for adding
7580 entries to the dictionary.

7623
Georg Brandl21e99f42010-03-07 15:23:59 +00007624- The enumerate() built-in function is no longer bounded to sequences
Georg Brandl3ee81df2008-05-17 18:14:43 +00007625 smaller than LONG_MAX. Formerly, it raised an OverflowError. Now,
7626 automatically shifts from ints to longs.
Raymond Hettinger8f669372007-10-03 21:18:11 +00007627
Georg Brandl3ee81df2008-05-17 18:14:43 +00007628- Issue #1686386: Tuple's tp_repr did not take into account the
7629 possibility of having a self-referential tuple, which is possible
7630 from C code. Nor did object's tp_str consider that a type's tp_str
7631 could do something that could lead to an inifinite recursion.
7632 Py_ReprEnter() and Py_EnterRecursiveCall(), respectively, fixed the
7633 issues.
Brett Cannon0b14f242007-09-30 19:45:10 +00007634
Georg Brandl3ee81df2008-05-17 18:14:43 +00007635- Issue #1164: It was possible to trigger deadlock when using the
7636 'print' statement to write to a file since the GIL was not released
7637 as needed. Now PyObject_Print() does the right thing along with
7638 various tp_print implementations of the built-in types and those in
7639 the collections module.
Brett Cannon01531592007-09-17 03:28:34 +00007640
Georg Brandl3ee81df2008-05-17 18:14:43 +00007641- Issue #1147: Exceptions were directly allowing string exceptions in
7642 their throw() method even though string exceptions no longer
7643 allowed.
Brett Cannon4c20bc42007-09-11 21:02:28 +00007644
Georg Brandl3ee81df2008-05-17 18:14:43 +00007645- Issue #1096: Prevent a segfault from getting the repr of a very
7646 deeply nested list by using the recursion counter.
Brett Cannona0c05512007-09-10 21:38:27 +00007647
Brett Cannon1e534b52007-09-07 04:18:30 +00007648- Issue #1202533: Fix infinite recursion calls triggered by calls to
Georg Brandl3ee81df2008-05-17 18:14:43 +00007649 PyObject_Call() never calling back out to Python code to trigger
7650 recursion depth updates/checks. Required the creation of a static
7651 RuntimeError instance in case normalizing an exception put the
7652 recursion check value past its limit. Fixes crashers
7653 infinite_rec_(1|2|4|5).py.
Brett Cannon1e534b52007-09-07 04:18:30 +00007654

Neal Norwitz0ac60192007-05-27 04:08:54 +00007668- Add new attribute names for function objects. All the func_* become
Georg Brandl3ee81df2008-05-17 18:14:43 +00007669 __*__ attributes. (Some already existed, e.g., __doc__ and
7670 __name__.)
Neal Norwitz0ac60192007-05-27 04:08:54 +00007671
Neal Norwitz8b2bfbc2007-05-23 06:35:32 +00007672- Add -3 option to the interpreter to warn about features that are
7673 deprecated and will be changed/removed in Python 3.0.
7674
Georg Brandl2134e752007-05-21 20:34:16 +00007675- Patch #1686487: you can now pass any mapping after '**' in function
7676 calls.
7677
Collin Winter62903052007-05-18 23:11:24 +00007678- except clauses may now be spelled either "except E, target:" or
Georg Brandl3ee81df2008-05-17 18:14:43 +00007679 "except E as target:". This is to provide forwards compatibility
7680 with Python 3.0.
Collin Winter62903052007-05-18 23:11:24 +00007681
Brett Cannon229cee22007-05-05 01:34:02 +00007682- Deprecate BaseException.message as per PEP 352.
7683
Georg Brandl3ee81df2008-05-17 18:14:43 +00007684- Issue #1303614: don't expose object's __dict__ when the dict is
Georg Brandl21e99f42010-03-07 15:23:59 +00007685 inherited from a built-in base.
Armin Rigo9790a272007-05-02 19:23:31 +00007686
Vinay Sajip8549ce32007-05-06 17:53:37 +00007687- When __slots__ are set to a unicode string, make it work the same as
Neal Norwitzcbd9ee62007-04-14 05:25:50 +00007688 setting a plain string, ie don't expand to single letter identifiers.
7689
Raymond Hettinger13936692007-04-11 18:40:58 +00007690- Request #1191699: Slices can now be pickled.
7691
Raymond Hettinger4db5fe92007-04-12 04:10:00 +00007692- Request #1193128: str.translate() now allows a None argument for
7693 translations that only remove characters without re-mapping the
7694 remaining characters.
7695
Georg Brandl5cb76c12007-03-21 09:00:39 +00007696- Patch #1682205: a TypeError while unpacking an iterable is no longer

7700
Guido van Rossum143b5642007-03-23 04:58:42 +00007701- Bug #1683368: The object.__init__() and object.__new__() methods are
7702 now stricter in rejecting excess arguments. The only time when
7703 either allows excess arguments is when it is not overridden and the
7704 other one is. For backwards compatibility, when both are
7705 overridden, it is a deprecation warning (for now; maybe a Py3k
Guido van Rossum234b1ff2007-03-23 19:39:01 +00007706 warning later). Also, type.__init__() insists on the same signature
7707 as supported by type.__new__().
Guido van Rossum143b5642007-03-23 04:58:42 +00007708
Georg Brandl3ee81df2008-05-17 18:14:43 +00007709- Patch #1675423: PyComplex_AsCComplex() now tries to convert an
7710 object to complex using its __complex__() method before falling back
7711 to the __float__() method. Therefore, the functions in the cmath
7712 module now can operate on objects that define a __complex__()
7713 method.
Georg Brandl2b869942007-03-17 16:08:45 +00007714
Georg Brandl3ee81df2008-05-17 18:14:43 +00007715- Patch #1623563: allow __class__ assignment for classes with
7716 __slots__. The old and the new class are still required to have the
7717 same slot names.

7723 ``object.__reduce_ex__()`` is called with an object that is faking
7724 its type.
Žiga Seilnacht20f43d32007-03-15 11:44:55 +00007725
Georg Brandl3ee81df2008-05-17 18:14:43 +00007726- Patch #1680015: Don't modify __slots__ tuple if it contains an

7730
Georg Brandl7b9c5552007-03-12 14:30:05 +00007731- Bug #1678647: write a newline after printing an exception in any
7732 case, even when converting the value to a string failed.
7733
Georg Brandl871f1bc2007-03-12 13:17:36 +00007734- The dir() function has been extended to call the __dir__() method on
Georg Brandl3ee81df2008-05-17 18:14:43 +00007735 its argument, if it exists. If not, it will work like before. This
7736 allows customizing the output of dir() in the presence of a
7737 __getattr__().
Georg Brandl871f1bc2007-03-12 13:17:36 +00007738
Collin Winter276887b2007-03-12 16:11:39 +00007739- Patch #922167: Python no longer segfaults when faced with infinitely

Georg Brandl3ee81df2008-05-17 18:14:43 +00007745- Patch #1491866: change the complex() constructor to allow
7746 parthensized forms. This means complex(repr(x)) now works instead of
7747 raising a ValueError.
Collin Wintere38051d2007-03-09 20:33:07 +00007748
Georg Brandlaa2321b2007-03-07 00:40:28 +00007749- Patch #703779: unset __file__ in __main__ after running a file. This
Georg Brandl3ee81df2008-05-17 18:14:43 +00007750 makes the filenames the warning module prints much more sensible
7751 when a PYTHONSTARTUP file is used.
Georg Brandlaa2321b2007-03-07 00:40:28 +00007752
Georg Brandl49aafc92007-03-07 00:34:46 +00007753- Variant of patch #697613: don't exit the interpreter on a SystemExit
7754 exception if the -i command line option or PYTHONINSPECT environment
Georg Brandl3ee81df2008-05-17 18:14:43 +00007755 variable is given, but break into the interactive interpreter just
7756 like on other exceptions or normal program exit.

Georg Brandl0fca97a2007-03-05 22:28:08 +00007764- Patch #1674228: when assigning a slice (old-style), check for the
7765 sq_ass_slice instead of the sq_slice slot.
7766
Georg Brandl3ee81df2008-05-17 18:14:43 +00007767- When printing an unraisable error, don't print exceptions. before
7768 the name. This duplicates the behavior whening normally printing
7769 exceptions.

8398 exception.

8671 members).
Walter Dörwald84a3efe2007-06-13 16:57:12 +00008672
Georg Brandl3ee81df2008-05-17 18:14:43 +00008673- Issue #829951: In the smtplib module, SMTP.starttls() now complies
8674 with RFC 3207 and forgets any knowledge obtained from the server not
8675 obtained from the TLS negotiation itself. Patch contributed by Bill
8676 Fenner.
Gregory P. Smith2b3ba582008-01-17 08:03:17 +00008677
Georg Brandl3ee81df2008-05-17 18:14:43 +00008678- Issue #1339: The smtplib.SMTP class has been refactored a bit such
Gregory P. Smithbde4ae42008-01-17 08:35:49 +00008679 that the SMTP.starttls() caller no longer needs to call ehlo()
8680 beforehand. SMTP.starttls() now raises an exception of the server
Georg Brandl3ee81df2008-05-17 18:14:43 +00008681 does not claim to support starttls. Adds the
8682 SMTP.ehlo_or_helo_if_needed() method. Patch contributed by Bill
8683 Fenner.

8721
Georg Brandl3ee81df2008-05-17 18:14:43 +00008722- Patch #1663329: added ``os.closerange()`` function to quickly close

8763 complex, tuple, list, dict, set, and frozenset. Formerly, it would
8764 silently miscode subclasses of those types. Now, it raises a
8765 ValueError instead.
Raymond Hettinger12e94202007-11-07 01:13:09 +00008766

Georg Brandl3ee81df2008-05-17 18:14:43 +00008781 time so that opening a database previously created with the DB_DUP
8782 or DB_DUPSORT flag set will keep the proper behavior on subsequent
8783 opens. Specifically: dictionary assignment to a DB object will
8784 replace all values for a given key when the database allows
8785 duplicate values. DB users should use DB.put(k, v) when they want
8786 to store duplicates; not DB[k] = v.
Gregory P. Smithec10a4a2007-11-05 02:32:26 +00008787

8793 characters with ASCII value less than 32. Also, it correctly quotes
8794 dots only if they occur on a single line, as opposed to the previous
8795 behavior of quoting dots if they are the second character of any
8796 line.
Georg Brandl4aef7272007-03-13 22:49:43 +00008797

9128-----
9129
Georg Brandl3ee81df2008-05-17 18:14:43 +00009130- Unified naming convention for free lists and their limits. All free
9131 lists in Object/ are named ``free_list``, the counter ``numfree``
9132 and the upper limit is a macro ``PyName_MAXFREELIST`` inside an
9133 #ifndef block.
Christian Heimes5b970ad2008-02-06 13:33:44 +00009134
Georg Brandl3ee81df2008-05-17 18:14:43 +00009135- ``PySet_Add()`` can now modify a newly created frozenset. Similarly
9136 to ``PyTuple_SetItem``, it can be used to populate a brand new
9137 frozenset; but it does not steal a reference to the added item.
Amaury Forgeot d'Arccab3d982008-02-03 22:51:43 +00009138
Vinay Sajipb7edfc42008-04-02 21:10:23 +00009139- Added ``PySet_Check()`` and ``PyFrozenSet_Check()`` to the set API.

9145- Patch #1720595: add T_BOOL to the range of structmember types.
9146
9147- Issue #1534: Added ``PyFloat_GetMax()``, ``PyFloat_GetMin()`` and
9148 ``PyFloat_GetInfo()`` to the float API.
9149
Georg Brandl3ee81df2008-05-17 18:14:43 +00009150- Issue #1521: On 64bit platforms, using PyArgs_ParseTuple with the t#
9151 of w# format code incorrectly truncated the length to an int, even
9152 when PY_SSIZE_T_CLEAN is set. The str.decode method used to return
9153 incorrect results with huge strings.
Georg Brandl6caad7d2008-01-26 14:19:22 +00009154
Georg Brandl3ee81df2008-05-17 18:14:43 +00009155- Issue #1629: Renamed Py_Size, Py_Type and Py_Refcnt to Py_SIZE,
9156 Py_TYPE and Py_REFCNT.

Georg Brandl3ee81df2008-05-17 18:14:43 +00009158- PEP 3123: Provide forward compatibility with Python 3.0, while
9159 keeping backwards compatibility. Add Py_Refcnt, Py_Type, Py_Size,
9160 and PyVarObject_HEAD_INIT.

9172
9173- Fix some leftovers from the conversion from int to Py_ssize_t
9174 (relevant to strings and sequences of more than 2**31 items).
9175
9176- Make _PyGILState_NoteThreadState() static, it was not used anywhere
9177 outside of pystate.c and should not be necessary.
9178
Georg Brandl3ee81df2008-05-17 18:14:43 +00009179- ``PyImport_Import`` and ``PyImport_ImportModule`` now always do
9180 absolute imports. In earlier versions they might have used relative
9181 imports under some conditions.
Christian Heimes000a0742008-01-03 22:16:32 +00009182
Georg Brandl3ee81df2008-05-17 18:14:43 +00009183- Added case insensitive comparison methods ``PyOS_stricmp(char*,
9184 char*)`` and ``PyOS_strnicmp(char*, char*, Py_ssize_t)``.
Christian Heimes000a0742008-01-03 22:16:32 +00009185
Georg Brandl3ee81df2008-05-17 18:14:43 +00009186- Bug #1542693: remove semi-colon at end of PyImport_ImportModuleEx

Georg Brandl3ee81df2008-05-17 18:14:43 +00009193- Patch #1706: Drop support for Win9x, WinME and NT4. Python now
9194 requires Windows 2000 or greater. The _WINVER and NTDDI_VERSION
9195 macros are set to Win2k for x86/32bit builds and WinXP for AMD64
9196 builds.
Christian Heimes95d64472008-02-09 19:55:22 +00009197

Georg Brandl3ee81df2008-05-17 18:14:43 +00009211- Removed the macfs module. It had been deprecated since Python 2.5.
9212 This lead to the deprecation of macostools.touched() as it relied
9213 solely on macfs and was a no-op under OS X.
