Ezio Melottiab2eb0e2010-06-05 19:21:32 +0000422- Issue #8271: during the decoding of an invalid UTF-8 byte sequence, only the
423 start byte and the continuation byte(s) are now considered invalid, instead
424 of the number of bytes specified by the start byte.
425 E.g.: '\xf1\x80AB'.decode('utf-8', 'replace') now returns u'\ufffdAB' and
426 replaces with U+FFFD only the start byte ('\xf1') and the continuation byte
427 ('\x80') even if '\xf1' is the start byte of a 4-bytes sequence.

437 objects. (1) The comparison could incorrectly return True in some cases
438 (2**53+1 == complex(2**53) == 2**53), breaking transivity of equality.
439 (2) The comparison raised an OverflowError for large integers, leading

824 with a non-empty format string. This is an effort to future-proof user
825 code. If a derived class does not currently implement __format__ but later
826 adds its own __format__, it would most likely break user code that had
827 supplied a format string. This will be changed to a DeprecationWaring in

Antoine Pitrouf3fa0742010-01-31 22:26:04 +00001316- Issue #6939: Fix file I/O objects in the `io` module to keep the original
Georg Brandlba83f822010-03-14 09:50:54 +00001317 file position when calling `truncate()`. It would previously change the file
1318 position to the given argument, which goes against the tradition of
Antoine Pitrouf3fa0742010-01-31 22:26:04 +00001319 ftruncate() and other truncation APIs. Patch by Pascal Chambon.

Georg Brandlba83f822010-03-14 09:50:54 +00001321- Issue #7610: Reworked implementation of the internal ``zipfile.ZipExtFile``
1322 class used to represent files stored inside an archive. The new
1323 implementation is significantly faster and can be wrapped in a
1324 ``io.BufferedReader`` object for more speedups. It also solves an issue
1325 where interleaved calls to ``read()`` and ``readline()`` give wrong results.

Georg Brandlba83f822010-03-14 09:50:54 +00001336- Issue #7748: Since unicode values are supported for some metadata options in

1338 encoded string for them. This ensures that the upload and register commands
1339 send the correct values to PyPI without any error.

1414-----------------
1415
Georg Brandlba83f822010-03-14 09:50:54 +00001416- The ``__complex__()`` method is now looked up on the class of instances to
1417 make it consistent with other special methods.

1421
Mark Dickinson1b34d252010-01-01 17:27:30 +00001422- Issue #5080: A number of functions and methods previously produced a
Georg Brandlba83f822010-03-14 09:50:54 +00001423 DeprecationWarning when passed a float argument where an integer was expected.
1424 These functions and methods now raise TypeError instead. The majority of the
1425 effects of this change are in the extension modules, but some core functions
1426 and methods are affected: notably the 'chr', 'range' and 'xrange' builtins,
1427 and many unicode/str methods.

1441 of integers: the result of a/b is now correctly rounded for ints a and b (at
1442 least on IEEE 754 platforms), and in particular does not depend on the
1443 internal representation of a long.

Georg Brandlba83f822010-03-14 09:50:54 +00001589- Issue #7419: ``locale.setlocale()`` could crash the interpreter on Windows
1590 when called with invalid values.

Georg Brandlba83f822010-03-14 09:50:54 +00001592- Issue #3382: 'F' formatting for float and complex now convert the result to
1593 upper case. This only affects 'inf' and 'nan', since 'f' no longer converts
1594 to 'g' for large values.
Amaury Forgeot d'Arcd7288712009-12-01 21:51:04 +00001595
Georg Brandlba83f822010-03-14 09:50:54 +00001596- Remove switch from "%f" formatting to "%g" formatting for floats larger than
1597 1e50 in absolute value.
Mark Dickinson9dd5e162009-11-23 20:54:09 +00001598
Georg Brandlba83f822010-03-14 09:50:54 +00001599- Remove restrictions on precision when formatting floats. E.g., "%.120g" %
1600 1e-100 used to raise OverflowError, but now gives the requested 120
1601 significant digits instead.
Mark Dickinson18cfada2009-11-23 18:46:41 +00001602

1608 10.6.
Ronald Oussoren315cd0c2009-11-19 16:25:21 +00001609
Georg Brandlba83f822010-03-14 09:50:54 +00001610- Issue #7117: ``repr(x)`` for a float x returns a result based on the shortest
1611 decimal string that's guaranteed to round back to x under correct rounding
1612 (with round-half-to-even rounding mode). Previously it gave a string based on
1613 rounding x to 17 decimal digits. repr(x) for a complex number behaves
1614 similarly. On platforms where the correctly-rounded strtod and dtoa code is
1615 not supported (see below), repr is unchanged.
Mark Dickinsonb678de82009-11-19 18:41:49 +00001616
Georg Brandlba83f822010-03-14 09:50:54 +00001617- Issue #7117: On almost all platforms: float-to-string and string-to-float
1618 conversions within Python are now correctly rounded. Places these conversions
1619 occur include: str for floats and complex numbers; the float and complex
1620 constructors; old-style and new-style numeric formatting; serialization and
1621 deserialization of floats and complex numbers using marshal, pickle and json;
1622 parsing of float and imaginary literals in Python code; Decimal-to-float
1623 conversion.
Mark Dickinsonb678de82009-11-19 18:41:49 +00001624
Georg Brandlba83f822010-03-14 09:50:54 +00001625 The conversions use a Python-adapted version of David Gay's well-known dtoa.c,
1626 providing correctly-rounded strtod and dtoa C functions. This code is
1627 supported on Windows, and on Unix-like platforms using gcc, icc or suncc as
1628 the C compiler. There may be a small number of platforms on which correct
1629 operation of this code cannot be guaranteed, so the code is not used: notably,
1630 this applies to platforms where the C double format is not IEEE 754 binary64,
1631 and to platforms on x86 hardware where the x87 FPU is set to 64-bit precision
1632 and Python's configure script is unable to determine how to change the FPU
1633 precision. On these platforms conversions use the platform strtod and dtoa,
1634 as before.
Mark Dickinsonb678de82009-11-19 18:41:49 +00001635
Georg Brandlba83f822010-03-14 09:50:54 +00001636- Issue #7117: Backport round implementation from Python 3.x. ``round()`` now
1637 uses the correctly-rounded string <-> float conversions described above (when
1638 available), and so produces correctly rounded results that will display nicely
1639 under the float repr. There are two related small changes: (1) round now
1640 accepts any class with an ``__index__()`` method for its second argument (but
1641 no longer accepts floats for the second argument), and (2) an excessively
1642 large second integer argument (e.g., ``round(1.234, 10**100)``) no longer
1643 raises an exception.

1646
Georg Brandlba83f822010-03-14 09:50:54 +00001647- Fix several issues with ``compile()``. The input can now contain Windows and

1787 (2) parsing of strings representing infinities and nans was locale aware; and
1788 (3) the interpretation of fromhex('-nan') didn't match that of float('-nan').

Georg Brandlba83f822010-03-14 09:50:54 +00001790- Issue #5920: For ``float.__format__()``, change the behavior with the empty
1791 presentation type (that is, not one of 'e', 'f', 'g', or 'n') to be like 'g'
1792 but with at least one decimal point and with a default precision
1793 of 12. Previously, the behavior the same but with a default precision of 6.
1794 This more closely matches ``str()``, and reduces surprises when adding
1795 alignment flags to the empty presentation type. This also affects the new
1796 complex.__format__ in the same way.
1797
1798- Issue #5890: In subclasses of 'property' the __doc__ attribute was shadowed by
1799 classtype's, even if it was None. property now inserts the __doc__ into the
1800 subclass instance __dict__.

Georg Brandlba83f822010-03-14 09:50:54 +00002020- On windows, ``os.chdir()`` given unicode was not working if
2021 GetCurrentDirectoryW returned a path longer than MAX_PATH. (But It's doubtful
2022 this code path is really executed because I cannot move to such directory on
2023 win2k)

Georg Brandlba83f822010-03-14 09:50:54 +00002025- Issue #4069: When ``set.remove(element)`` is used with a set element, the
2026 element is temporarily replaced with an equivalent frozenset. But the
2027 eventual KeyError would always report the empty ``frozenset()`` as the missing
2028 key. Now it correctly refers to the initial element.

Walter Dörwalded960ac2009-05-03 22:36:33 +00002048- Issue #5108: Handle %s like %S and %R in PyUnicode_FromFormatV(): Call
2049 PyUnicode_DecodeUTF8() once, remember the result and output it in a second
2050 step. This avoids problems with counting UTF-8 bytes that ignores the effect
2051 of using the replace error handler in PyUnicode_DecodeUTF8().
2052
Walter Dörwald726ba8e2009-05-06 14:32:35 +00002053- Issue #3739: The unicode-internal encoder now reports the number of characters

2055
Georg Brandlba83f822010-03-14 09:50:54 +00002056- Issue #2422: When compiled with the ``--with-valgrind`` option, the pymalloc

2058 gives improved memory leak detection when running under Valgrind, while taking
2059 advantage of pymalloc at other times.

Georg Brandlba83f822010-03-14 09:50:54 +00003282 leak-chasing test runs give sensible results. The previous method of reaping
3283 threads could return successfully while some Thread objects were still
3284 referenced. This also introduces a new private function: ``thread._count()``.

3406 exactly the recursion limit is exceeded. Consequently, both exception types
3407 are caught and silenced.

3423
Martin v. Löwis9fa5a282008-09-11 06:53:30 +00003424- Issue #3642: Suppress warning in obmalloc when size_t is larger than uint.
3425
Amaury Forgeot d'Arc05e34492008-09-10 22:04:45 +00003426- Issue #3743: In a few places, PY_FORMAT_SIZE_T was incorrectly used with
3427 PyString_FromFormat or PyErr_Format to display size_t values. The macro
3428 PY_FORMAT_SIZE_T is designed to select the correct format for the OS
3429 ``printf`` function, whereas PyString_FromFormat has an independent
3430 implementation and uses "%zd" on all platforms for size_t values.
3431 This makes a difference on win64, where ``printf`` needs "%Id" to display
3432 64bit values.
3433
Benjamin Peterson97179b02008-09-09 20:55:01 +00003434- Issue #3634: _weakref.ref(Exception).__init__() gave invalid return value on
3435 error.
3436
Amaury Forgeot d'Arcd3ffb892008-09-09 07:24:30 +00003437- Issue #3777: long() applied to a float object now always return a long
3438 object; previously an int would be returned for small values. the __long__
3439 method is allowed to return either an int or a long, but the behaviour of
3440 float objects should not change to respect backward compatibility.
3441
Amaury Forgeot d'Arc3571fbf2008-09-01 19:52:00 +00003442- Issue #3751: str.rpartition would perform a left-partition when called with
3443 a unicode argument.
3444
Benjamin Peterson17f03ca2008-09-01 14:18:30 +00003445- Issue #3683: Fix compilation when --without-threads is given.
3446
Antoine Pitroud4ae97b2008-08-29 18:39:48 +00003447- Issue #3668: Fix a memory leak with the "s*" argument parser in
Vinay Sajip35e3b032008-09-01 14:33:59 +00003448 PyArg_ParseTuple and friends, which occurred when the argument for "s*"
Antoine Pitroud4ae97b2008-08-29 18:39:48 +00003449 was correctly parsed but parsing of subsequent arguments failed.
3450
Vinay Sajip35e3b032008-09-01 14:33:59 +00003451- Issue #2534: speed up isinstance() and issubclass() by 50-70%, so as to
Antoine Pitrou0668c622008-08-26 22:42:08 +00003452 match Python 2.5 speed despite the __instancecheck__ / __subclasscheck__
3453 mechanism. In the process, fix a bug where isinstance() and issubclass(),
3454 when given a tuple of classes as second argument, were looking up
3455 __instancecheck__ / __subclasscheck__ on the tuple rather than on each
3456 type object.
3457
Neal Norwitz18aa3882008-08-24 05:04:52 +00003458- Fix crashes on memory allocation failure found with failmalloc.
3459
3460- Fix memory leaks found with valgrind and update suppressions file.
3461
3462- Fix compiler warnings in opt mode which would lead to invalid memory reads.
3463
3464- Fix problem using wrong name in decimal module reported by pychecker.
3465
Christian Heimes7d4c3172008-08-22 19:47:25 +00003466- Silenced another compiler warning about a used but not defined
3467 function 'stringlib_contains_obj'.
3468
Benjamin Peterson712ee922008-08-24 18:10:20 +00003469- Added warnings on the use of ``__getslice__``, ``__setslice__``, or
3470 ``__delslice__``.
3471
Gregory P. Smith2bb25cc2008-09-02 05:29:51 +00003472- Issue #3678: Correctly pass LDFLAGS and LDLAST to the linker on shared
3473 library targets in the Makefile.
3474
Gregory P. Smith980b99b2008-09-07 05:15:18 +00003475- Issue #1204: The configure script now tests for additional libraries
3476 that may be required when linking against readline. This fixes issues
3477 with x86_64 builds on some platforms (a few Linux flavors and OpenBSD).

Brett Cannon672237d2008-09-09 00:49:16 +00003501 return a list or None rather than a custom object.
3502
Benjamin Peterson6ac7d7c2008-09-06 19:28:11 +00003503- Issue #1638033: Cookie.Morsel gained the httponly attribute.

Brett Cannon1eaf0742008-09-02 01:25:16 +00003527 warnings.catch_warnings() along with some API cleanup. Expanding the tests
3528 for catch_warnings() also led to an improvement in the raising of a
3529 DeprecationWarning related to warnings.warn_explicit().
3530
Benjamin Peterson973e6c22008-09-01 23:12:58 +00003531- The deprecation warnings for the old camelCase threading API were removed.

Amaury Forgeot d'Arc293924b2008-09-02 23:19:56 +00003554- Issue #2975: When compiling several extension modules with Visual Studio 2008
3555 from the same python interpreter, some environment variables would grow
3556 without limit.
3557
Benjamin Peterson37346b22008-08-23 20:27:43 +00003558- Issue #3643: Added a few more checks to _testcapi to prevent segfaults by

Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00003595What's New in Python 2.6 beta 3?
3596================================
3597
Barry Warsaw07a4a382008-08-21 01:15:08 +00003598*Release date: 20-Aug-2008*
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00003599
3600Core and Builtins
3601-----------------
3602
Guido van Rossumf8402962008-08-20 15:01:50 +00003603- Issue #1878: Remove Py_TPFLAGS_HAVE_VERSION_TAG from
3604 Py_TPFLAGS_DEFAULT when not building the core. This means 3rd party
3605 extensions do not automatically benefit from the class attribute
3606 cache; they will have to explicitly add Py_TPFLAGS_HAVE_VERSION_TAG
3607 to their tp_flags field if they care. This is a backwards
3608 compatibility feature; in 3.0, all types will use the cache by
3609 default.
3610
Benjamin Petersonf647dc12008-08-20 01:27:30 +00003611- Keyword arguments can now follow starred arguments. (``f(a, *args,
3612 keyword=23)`` is now valid syntax.)
3613
Thomas Heller0ad5ae02008-08-19 19:25:04 +00003614- ctypes function pointers that are COM methods have a boolean True
3615 value again.
3616
Martin v. Löwisf91d46a2008-08-12 14:49:50 +00003617- Issue #3139: Make buffer-interface thread-safe wrt. PyArg_ParseTuple,
3618 by denying s# to parse objects that have a releasebuffer procedure,
3619 and introducing s*.
3620
Georg Brandl1e13ea92008-08-11 09:07:59 +00003621- Issue #3537: Fix an assertion failure when an empty but presized dict
3622 object was stored in the freelist.
3623
Mark Dickinsonb6467572008-08-04 21:30:09 +00003624- Issue #1481296: Make long(float('nan')) and int(float('nan')) raise
3625 ValueError consistently across platforms.
3626
Amaury Forgeot d'Arc39fd6722008-07-31 21:28:03 +00003627- Issue #3479: On platforms where sizeof(int) is smaller than sizeof(long)
3628 (64bit Unix, for example), unichr() would truncate its argument and return
3629 u'\x00' for unichr(2**32). Now it properly raises an OverflowError.
3630
Neal Norwitze7d8be82008-07-31 17:17:14 +00003631- Apply security patches from Apple.
3632
Amaury Forgeot d'Arc246daed2008-07-31 00:42:16 +00003633- Issue #2542: Now that issubclass() may call arbitrary code, ensure that
3634 PyErr_ExceptionMatches returns 0 when an exception occurs there.
3635
Antoine Pitrou92f82162008-07-25 22:22:08 +00003636- Issue #1819: function calls with several named parameters are now on
3637 average 35% faster (as measured by pybench).
3638
Amaury Forgeot d'Arce4921fe2008-07-21 22:00:38 +00003639- Issue #2378: An unexpected UnboundLocalError or NameError could appear when
3640 the python debugger steps into a class statement: the free variables (local
3641 variables defined in an outer scope) would be deleted from the outer scope.
3642
Gregory P. Smith0470bab2008-07-22 04:46:32 +00003643- Issue #2620: Overflow checking when allocating or reallocating memory
3644 was not always being done properly in some python types and extension
3645 modules. PyMem_MALLOC, PyMem_REALLOC, PyMem_NEW and PyMem_RESIZE have
3646 all been updated to perform better checks and places in the code that
3647 would previously leak memory on the error path when such an allocation
3648 failed have been fixed.

Benjamin Petersone977ad42008-08-20 01:42:01 +00003655- The methods ``is_in_tuple()``, ``is_vararg()``, and ``is_keywordarg()`` of
3656 symtable.Symbol have been deprecated for removal in 3.0 and the next release.
3657
Amaury Forgeot d'Arc351ffb82008-08-18 19:23:47 +00003658- Issue #2234: distutils failed for some versions of the cygwin compiler. The
3659 version reported by these tools does not necessarily follow the python
3660 version numbering scheme, so the module is less strict when parsing it.
3661
Nick Coghlanf70385a2008-08-18 12:42:46 +00003662- Issue #2235: Added Py3k warnings for types which will become unhashable
3663 under the stricter __hash__ inheritance rules in 3.0. Several types
3664 which did not meet the rules for hash invariants and were already
3665 unhashable in 3.0 have now been explicitly flagged as unhashable in
3666 2.6 as well (collections.Mapping, collections.Set, unittest.TestSuite,
3667 xml.dom.minidom.NamedNodeMap, numbers.Number, UserList.UserList)
3668
Brett Cannon88f801d2008-08-18 00:46:22 +00003669- Update __all__ for cookielib, csv, os, urllib2, and weakref to include things
3670 imported into the module but exposed as part of the module's API.
3671

3677
Hirokazu Yamamoto41a81eb2008-08-17 13:10:46 +00003678- Issue #3575: Incremental decoder's decode function now takes bytearray
3679 by using 's*' instead of 't#'.
3680
Mark Dickinson3e4caeb2009-02-21 20:27:01 +00003681- Issue #2222: Fixed reference leak when occurred os.rename()
Hirokazu Yamamoto7f30a682008-08-17 09:46:56 +00003682 fails unicode conversion on 2nd parameter. (windows only)
3683
Georg Brandl222e2082010-08-01 22:27:39 +00003684- Issue #2464: urllib2 now supports a malformation in the URL received
Facundo Batista94f243a2008-08-17 03:38:39 +00003685 in a redirect.
3686

3716 to _sre.compile() will now be rejected. This should not affect anybody
3717 since the re.compile() function never generates invalid re-bytecode.

Antoine Pitroude781a42008-08-09 12:43:23 +00003738 asking for a specific length. This problem only affected files opened
3739 using the new "io" module, not the built-in open() function.

3765 file name rather than a ZipInfo instance, so files are extracted with
3766 mode 0600 rather than 000 under Unix.
3767
Gregory P. Smitha36f8fe2008-08-04 00:13:29 +00003768- Issue #1857: subprocess.Popen.poll gained an additional _deadstate keyword

3781 interaction with the tp_hash slot (added in 2.6b2) are now documented
3782
Nick Coghlan2a0c2b12008-08-04 12:47:17 +00003783- Issue #643841: The language reference now provides more detailed
3784 coverage of the lookup process for special methods. The disclaimers
3785 regarding lack of coverage of new-style classes have also been
3786 removed, since the coverage is now fairly reasonable.

3795-----------------
3796
Georg Brandl3e483f62008-07-16 22:57:41 +00003797- Issue #3156: Fix inconsistent behavior of the bytearray type: all
3798 its methods now allow for items objects that can be converted to
3799 an integer using operator.index().
3800
Mark Dickinson64b7e502008-07-16 09:40:03 +00003801- Issue #3360: Fix incorrect parsing of '020000000000.0', which
3802 produced a ValueError instead of giving the correct float.
3803
Eric Smitha5fa5a22008-07-16 00:11:49 +00003804- Issue #3083: Add alternate (#) formatting for bin, oct, hex output
3805 for str.format(). This adds the prefix 0b, 0o, or 0x, respectively.
3806
Mark Dickinson7103aa42008-07-15 19:08:33 +00003807- Issue #3008: the float type has a new instance method 'float.hex'
3808 and a new class method 'float.fromhex' to convert floating-point
3809 numbers to and from hexadecimal strings, respectively.
3810
Nick Coghlan6d6bd442008-07-15 15:40:22 +00003811- Issue #2235: __hash__ is once again inherited by default. To allow
3812 collections.Hashable to remain meaningful in the presence of the
3813 default hash implementation (object.__hash__), it is now possible
3814 to explicit block inheritance of hash by setting __hash__=None at
3815 the Python level, or tp_hash=PyObject_HashNotImplemented at the C
3816 level.
3817
Nick Coghlanb028f502008-07-13 14:52:36 +00003818- Issue #3221: Issue a RuntimeWarning instead of raising SystemError if
3819 the parent module cannot be found while performing an absolute import.
3820 This means that an incorrectly defined __package__ attribute will
3821 now only prevent relative imports in that module rather than causing
3822 all imports from that module to fail.
3823
Nick Coghlan14ff9942008-07-08 14:21:42 +00003824- Issue #2517: Allow unicode messages in Exceptions again by correctly

3834 another thread's dictionary.
3835
Mark Dickinson1ec2fcd2008-06-20 14:53:43 +00003836- Issue #3004: Minor change to slice.indices(): the start and stop
3837 arguments are now treated identically, making the behaviour easier
3838 to describe and understand. For example, slice(None, -10,
3839 1).indices(9) now returns (0, 0, 1) instead of (0, -1, 1), and
3840 slice(None, 10, -1).indices(10) returns (9, 9, -1) instead of (9,
3841 10, -1).
3842
Georg Brandl278fc502008-07-19 12:46:12 +00003843- Issue #3219: Calling a function with repeated keyword arguments,
3844 f(a=2, a=23), would not cause a syntax error. This was a regression
3845 from 2.4 caused by the switch to the new compiler.

Georg Brandl278fc502008-07-19 12:46:12 +00003847- Issue #2862: Make int and float freelist management consistent with
3848 other freelists. Changes their CompactFreeList apis into

3855 api functions without holding the GIL, which could lead to a fatal
3856 error when they failed.
3857
Martin v. Löwisaabf4042008-08-02 07:20:25 +00003858- Issue #799428: Fix Tkinter.Misc._nametowidget to unwrap Tcl command objects.

Amaury Forgeot d'Arc0f7cddc2008-07-06 21:34:39 +00003883- Issue #839496: SimpleHTTPServer used to open text files in text mode. This is
3884 both unnecessary (HTTP allows text content to be sent in several forms) and
Andrew M. Kuchlingcc3f2b12008-07-10 14:43:31 +00003885 wrong because the actual transmitted size could differ from the
Amaury Forgeot d'Arc0f7cddc2008-07-06 21:34:39 +00003886 content-length. The problem had been corrected in the 2.4 branch, but never
3887 merged into trunk.

Nick Coghlanc060b0e2008-07-02 13:09:19 +00003902- Issue #3190: Pydoc now hides the automatic module attribute __package__ (the

3904
Brett Cannon8bb8fa52008-07-02 01:57:08 +00003905- Issue #2885 (partial): The urllib.urlopen() function has been deprecated for

Brett Cannonb61d8012008-05-11 23:39:04 +00004291- ``Lib/lib-old`` is now added to sys.path.
4292
Ronald Oussoren5640ce22008-06-05 12:58:24 +00004293- On MacOS X it is now possible to install the framework in 64-bit
4294 mode or even as a 4-way universal binary (that is, PPC, i386,
Georg Brandl5cc774e2008-06-11 20:28:06 +00004295 PPC64 and x86_64 support in one binary).
Ronald Oussoren5640ce22008-06-05 12:58:24 +00004296
4297 This is controlled by the configure argument ``--with-universal-archs``:
4298
4299 - ``--with-universal-archs=all``: install 4-way universal
4300
4301 - ``--with-universal-archs=32-bit``: install 2-way universal, 32-bit (the default)
4302
4303 - ``--with-universal-archs=64-bit``: install 2-way universal, 64-bit
4304
4305 This option should be used in combination with ``--enable-universalsdk=``.
4306
4307 NOTE: 64-bit and 4-way builds are only suppported on Mac OS X 10.5 (or later).

Georg Brandl3ee81df2008-05-17 18:14:43 +00004357- Issue #1631171: Re-implement the 'warnings' module in C (the
4358 original Python code has been kept as backup). This will allow for
4359 using the 'warning's machinery in such places as the parser where
4360 use of pure Python code is not possible. Both the ``showarning()``
4361 and ``formatwarning()`` gain an optional 'line' argument which is
4362 not called by default for backwards-compatibility reasons. Setting
4363 ``warnings.showwarning()`` to an implementation that lacks support
4364 for the ``line`` argument will raise a DeprecationWarning.

Georg Brandl3ee81df2008-05-17 18:14:43 +00004406- Issue #2513: distutils on Windows is now capable of cross-compiling
Mark Hammond495cf992008-04-07 01:53:39 +00004407 extension modules between 32 and 64 bit platforms. See the distutls

Georg Brandl3ee81df2008-05-17 18:14:43 +00004427- Issue #2550: The approach used by client/server code for obtaining
4428 ports to listen on in network-oriented tests has been refined in an
4429 effort to facilitate running multiple instances of the entire
4430 regression test suite in parallel without issue.
4431 test_support.bind_port() has been fixed such that it will always
4432 return a unique port -- which wasn't always the case with the
4433 previous implementation, especially if socket options had been set
4434 that affected address reuse (i.e. SO_REUSEADDR, SO_REUSEPORT). The
4435 new implementation of bind_port() will actually raise an exception
4436 if it is passed an AF_INET/SOCK_STREAM socket with either the
4437 SO_REUSEADDR or SO_REUSEPORT socket option set. Furthermore, if
4438 available, bind_port() will set the SO_EXCLUSIVEADDRUSE option on
4439 the socket it's been passed. This currently only applies to
4440 Windows. This option prevents any other sockets from binding to the
4441 host/port we've bound to, thus removing the possibility of the
4442 'non-deterministic' behaviour, as Microsoft puts it, that occurs
4443 when a second SOCK_STREAM socket binds and accepts to a host/port
4444 that's already been bound by another socket. The optional preferred
4445 port parameter to bind_port() has been removed. Under no
4446 circumstances should tests be hard coding ports!
4447
4448 test_support.find_unused_port() has also been introduced, which will
4449 pass a temporary socket object to bind_port() in order to obtain an
4450 unused port. The temporary socket object is then closed and
4451 deleted, and the port is returned. This method should only be used
4452 for obtaining an unused port in order to pass to an external program
4453 (i.e. the -accept [port] argument to openssl's s_server mode) or as
4454 a parameter to a server-oriented class that doesn't give you direct
4455 access to the underlying socket used.
4456
4457 Finally, test_support.HOST has been introduced, which should be used
4458 for the host argument of any relevant socket calls (i.e. bind and
4459 connect).
Trent Nelsone41b0062008-04-08 23:47:30 +00004460
4461 The following tests were updated to following the new conventions:
Georg Brandl3ee81df2008-05-17 18:14:43 +00004462 test_socket, test_smtplib, test_asyncore, test_ssl, test_httplib,
Trent Nelsone41b0062008-04-08 23:47:30 +00004463 test_poplib, test_ftplib, test_telnetlib, test_socketserver,
4464 test_asynchat and test_socket_ssl.
4465
Georg Brandl3ee81df2008-05-17 18:14:43 +00004466 It is now possible for multiple instances of the regression test
4467 suite to run in parallel without issue.

Eric Smitha73fbe72008-02-23 03:09:44 +00004746- Added the future_builtins module, which contains hex() and oct().
4747 These are the PEP 3127 version of these functions, designed to be
4748 compatible with the hex() and oct() builtins from Python 3.0. They
4749 differ slightly in their output formats from the existing, unchanged
4750 Python 2.6 builtins. The expected usage of the future_builtins
4751 module is:
4752 from future_builtins import hex, oct
4753
Eric Smith7ef40bf2008-02-20 23:34:22 +00004754- Issue #1600: Modifed PyOS_ascii_formatd to use at most 2 digit
4755 exponents for exponents with absolute value < 100. Follows C99
4756 standard. This is a change on Windows, which would use 3 digits.
4757 Also, added 'n' to the formats that PyOS_ascii_formatd understands,
4758 so that any alterations it does to the resulting string will be
4759 available in stringlib/formatter.h (for float.__format__).
4760
Eric Smith5a3c1352008-02-19 13:21:56 +00004761- Implemented PEP 3101, Advanced String Formatting. This adds a new
4762 builtin format(); a format() method for str and unicode; a
4763 __format__() method to object, str, unicode, int, long, float, and
4764 datetime; the class string.Formatter; and the C API
4765 PyObject_Format().
4766
Georg Brandl3ee81df2008-05-17 18:14:43 +00004767- Fixed several potential crashes, all caused by specially crafted
4768 __del__ methods exploiting objects in temporarily inconsistent
4769 state.

4773 a slot on a registered virtual subclass.

4776 real or imaginary part.
Christian Heimes2f0da532008-02-15 06:57:08 +00004777
Georg Brandl3ee81df2008-05-17 18:14:43 +00004778- Clear all free lists during a gc.collect() of the highest generation
4779 in order to allow pymalloc to free more arenas. Python may give back
4780 memory to the OS earlier.
Christian Heimes3b718a72008-02-14 12:47:33 +00004781
Georg Brandl3ee81df2008-05-17 18:14:43 +00004782- Issue #2045: Fix an infinite recursion triggered when printing a
4783 subclass of collections.defaultdict, if its default_factory is set
4784 to a bound method.
Amaury Forgeot d'Arcb01aa432008-02-08 00:56:02 +00004785
Christian Heimesf75dbef2008-02-08 00:11:31 +00004786- Fixed a minor memory leak in dictobject.c. The content of the free
4787 list was not freed on interpreter shutdown.
4788
Georg Brandl21e99f42010-03-07 15:23:59 +00004789- Limit free list of method and built-in function objects to 256
Georg Brandl3ee81df2008-05-17 18:14:43 +00004790 entries each.
Christian Heimes6075a822008-02-06 12:44:34 +00004791
Georg Brandl3ee81df2008-05-17 18:14:43 +00004792- Patch #1953: Added ``sys._compact_freelists()`` and the C API
4793 functions ``PyInt_CompactFreeList`` and ``PyFloat_CompactFreeList``
Christian Heimes422051a2008-02-04 18:00:12 +00004794 to compact the internal free lists of pre-allocted ints and floats.
4795
Georg Brandl3ee81df2008-05-17 18:14:43 +00004796- Issue #1983: Fixed return type of fork(), fork1() and forkpty()
4797 calls. Python expected the return type int but the fork familie
4798 returns pi_t.
Christian Heimes951cc0f2008-01-31 23:08:23 +00004799
Georg Brandl3ee81df2008-05-17 18:14:43 +00004800- Issue #1678380: Fix a bug that identifies 0j and -0j when they
4801 appear in the same code unit.
Mark Dickinson105be772008-01-31 22:17:37 +00004802
Georg Brandl3ee81df2008-05-17 18:14:43 +00004803- Issue #2025: Add tuple.count() and tuple.index() methods to comply
4804 with the collections.Sequence API.
Raymond Hettinger5b07ebc2008-02-07 00:54:20 +00004805
Georg Brandl3ee81df2008-05-17 18:14:43 +00004806- Patch #1970 by Antoine Pitrou: Speedup unicode whitespace and
4807 linebreak detection

Georg Brandl3ee81df2008-05-17 18:14:43 +00004809- Added ``PyType_ClearCache()`` and ``sys._clear_type_cache`` to clear
4810 the internal lookup cache for ref leak tests.
Christian Heimes908caac2008-01-27 23:34:59 +00004811
Georg Brandl3ee81df2008-05-17 18:14:43 +00004812- Patch #1473257: generator objects gain a gi_code attribute. This is
4813 the same object as the func_code attribute of the function that
4814 produced the generator.
Georg Brandl0cdf9a32008-01-26 14:14:20 +00004815
Georg Brandl3ee81df2008-05-17 18:14:43 +00004816- Issue #1920: "while 0" statements were completely removed by the
4817 compiler, even in the presence of an "else" clause, which is
4818 supposed to be run when the condition is false. Now the compiler
4819 correctly emits bytecode for the "else" suite.
Amaury Forgeot d'Arc31eaafe2008-01-24 22:59:25 +00004820
Guido van Rossumeead05f2008-01-24 18:21:02 +00004821- A few crashers fixed: weakref_in_del.py (issue #1377858);
4822 loosing_dict_ref.py (issue #1303614, test67.py);
4823 borrowed_ref_[34].py (not in tracker).
4824
Vinay Sajipd7cf32e2008-01-24 12:43:33 +00004825- Issue #1069410: The "can't load dll" message box on Windows is
Christian Heimesb2302ba2008-01-23 17:15:06 +00004826 suppressed while an extension is loaded by calling SetErrorMode in
4827 dynload_win.c. The error is still reported properly.
4828
Georg Brandl3ee81df2008-05-17 18:14:43 +00004829- Issue #1915: Python compiles with --enable-unicode=no again. However
Christian Heimes082c9b02008-01-23 14:20:50 +00004830 several extension methods and modules do not work without unicode
4831 support.
4832
Georg Brandl26543b12008-01-21 18:36:51 +00004833- Issue #1882: when compiling code from a string, encoding cookies in the
4834 second line of code were not always recognized correctly.
4835
Georg Brandl14404b62008-01-19 19:27:05 +00004836- Issue #1679: "0x" was taken as a valid integer literal.
4837
Georg Brandl6caad7d2008-01-26 14:19:22 +00004838- Issue #1865: ``bytes`` as an alias for ``str`` and b"" as an alias "" were
Christian Heimes288e89a2008-01-18 18:24:07 +00004839 added.
4840
Christian Heimesc94e2b52008-01-14 04:13:37 +00004841- sys.float_info / PyFloat_GetInfo: The floating point information
4842 object was converted from a dict to a specialized structseq object.
4843
Georg Brandl3ee81df2008-05-17 18:14:43 +00004844- Patch #1816: Added sys.flags structseq. It exposes the status of
4845 most command line arguments and PYTHON* environment variables.
Christian Heimesf31b69f2008-01-14 03:42:48 +00004846
Georg Brandl3ee81df2008-05-17 18:14:43 +00004847- Objects/structseq.c: Implemented new structseq representation. The
4848 patch makes structseqs (e.g. the return value of os.stat) more
4849 readable.
Christian Heimes9c201962008-01-14 03:33:52 +00004850
Georg Brandl3ee81df2008-05-17 18:14:43 +00004851- Patch #1700288: added a type attribute cache that caches method
4852 accesses, resulting in speedups in heavily object-oriented code.
Amaury Forgeot d'Arce4c270c2008-01-14 00:29:41 +00004853
Neal Norwitz3fc15b82008-01-10 05:42:58 +00004854- Bug #1776: __import__() no longer accepts filenames on any platform.
4855 The first parameter to __import__() must be a valid module name.
Christian Heimes3403f152008-01-09 19:56:33 +00004856
Georg Brandlaed6c662008-01-07 17:25:53 +00004857- Patch #1668: renamed THREADDEBUG envvar to PYTHONTHREADDEBUG.
4858
Georg Brandl3ee81df2008-05-17 18:14:43 +00004859- Patch #602345: Add -B command line option, PYTHONDONTWRITEBYTECODE
4860 envvar and sys.dont_write_bytecode attribute. All these can be set
4861 to forbid Python to attempt to write compiled bytecode files.
Georg Brandl2da0fce2008-01-07 17:09:35 +00004862
Georg Brandl3ee81df2008-05-17 18:14:43 +00004863- Improve some exception messages when Windows fails to load an
4864 extension module. Now we get for example '%1 is not a valid Win32
4865 application' instead of 'error code 193'.
Amaury Forgeot d'Arce0b76952008-01-04 02:04:15 +00004866
Georg Brandl3ee81df2008-05-17 18:14:43 +00004867- Bug #1481296: Fixed long(float('nan')) != 0L.

4870 y) functions.
Christian Heimese2ca4242008-01-03 20:23:15 +00004871
Christian Heimes0a8143f2007-12-18 23:22:54 +00004872- Issue #1635: Platform independent creation and representation of NaN
Georg Brandl3ee81df2008-05-17 18:14:43 +00004873 and INF. float("nan"), float("inf") and float("-inf") now work on
4874 every platform with IEEE 754 semantics.
Christian Heimes0a8143f2007-12-18 23:22:54 +00004875
Georg Brandl3ee81df2008-05-17 18:14:43 +00004876- Compiler now generates simpler and faster code for dictionary
4877 literals. The oparg for BUILD_MAP now indicates an estimated
4878 dictionary size. There is a new opcode, STORE_MAP, for adding
4879 entries to the dictionary.

Georg Brandl3ee81df2008-05-17 18:14:43 +00004908- Patch #1739468: Directories and zipfiles containing a __main__.py
4909 file can now be directly executed by passing their name to the
4910 interpreter. The directory/zipfile is automatically inserted as the
4911 first entry in sys.path.
Nick Coghlan327a39b2007-11-18 11:56:28 +00004912
Georg Brandl3ee81df2008-05-17 18:14:43 +00004913- Issue #1265: Fix a problem with sys.settrace, if the tracing
4914 function uses a generator expression when at the same time the
4915 executed code is closing a paused generator.
Amaury Forgeot d'Arc0d75f092007-11-13 21:54:28 +00004916
Raymond Hettinger1760c8a2007-11-08 02:52:43 +00004917- sets and frozensets now have an isdisjoint() method.
4918
Raymond Hettinger3f8caa32007-10-24 01:28:33 +00004919- optimize the performance of builtin.sum().
4920
Neal Norwitz44f326e2007-10-05 05:29:17 +00004921- Fix warnings found by the new version of the Coverity checker.
4922
Georg Brandl21e99f42010-03-07 15:23:59 +00004923- The enumerate() built-in function is no longer bounded to sequences
Georg Brandl3ee81df2008-05-17 18:14:43 +00004924 smaller than LONG_MAX. Formerly, it raised an OverflowError. Now,
4925 automatically shifts from ints to longs.
Raymond Hettinger8f669372007-10-03 21:18:11 +00004926
Georg Brandl3ee81df2008-05-17 18:14:43 +00004927- Issue #1686386: Tuple's tp_repr did not take into account the
4928 possibility of having a self-referential tuple, which is possible
4929 from C code. Nor did object's tp_str consider that a type's tp_str
4930 could do something that could lead to an inifinite recursion.
4931 Py_ReprEnter() and Py_EnterRecursiveCall(), respectively, fixed the
4932 issues.
Brett Cannon0b14f242007-09-30 19:45:10 +00004933
Georg Brandl3ee81df2008-05-17 18:14:43 +00004934- Issue #1164: It was possible to trigger deadlock when using the
4935 'print' statement to write to a file since the GIL was not released
4936 as needed. Now PyObject_Print() does the right thing along with
4937 various tp_print implementations of the built-in types and those in
4938 the collections module.
Brett Cannon01531592007-09-17 03:28:34 +00004939
Georg Brandl3ee81df2008-05-17 18:14:43 +00004940- Issue #1147: Exceptions were directly allowing string exceptions in
4941 their throw() method even though string exceptions no longer
4942 allowed.
Brett Cannon4c20bc42007-09-11 21:02:28 +00004943
Georg Brandl3ee81df2008-05-17 18:14:43 +00004944- Issue #1096: Prevent a segfault from getting the repr of a very
4945 deeply nested list by using the recursion counter.
Brett Cannona0c05512007-09-10 21:38:27 +00004946
Brett Cannon1e534b52007-09-07 04:18:30 +00004947- Issue #1202533: Fix infinite recursion calls triggered by calls to
Georg Brandl3ee81df2008-05-17 18:14:43 +00004948 PyObject_Call() never calling back out to Python code to trigger
4949 recursion depth updates/checks. Required the creation of a static
4950 RuntimeError instance in case normalizing an exception put the
4951 recursion check value past its limit. Fixes crashers
4952 infinite_rec_(1|2|4|5).py.
Brett Cannon1e534b52007-09-07 04:18:30 +00004953

Neal Norwitz0ac60192007-05-27 04:08:54 +00004967- Add new attribute names for function objects. All the func_* become
Georg Brandl3ee81df2008-05-17 18:14:43 +00004968 __*__ attributes. (Some already existed, e.g., __doc__ and
4969 __name__.)
Neal Norwitz0ac60192007-05-27 04:08:54 +00004970
Neal Norwitz8b2bfbc2007-05-23 06:35:32 +00004971- Add -3 option to the interpreter to warn about features that are
4972 deprecated and will be changed/removed in Python 3.0.
4973
Georg Brandl2134e752007-05-21 20:34:16 +00004974- Patch #1686487: you can now pass any mapping after '**' in function
4975 calls.
4976
Collin Winter62903052007-05-18 23:11:24 +00004977- except clauses may now be spelled either "except E, target:" or
Georg Brandl3ee81df2008-05-17 18:14:43 +00004978 "except E as target:". This is to provide forwards compatibility
4979 with Python 3.0.

Brett Cannon229cee22007-05-05 01:34:02 +00004981- Deprecate BaseException.message as per PEP 352.
4982
Georg Brandl3ee81df2008-05-17 18:14:43 +00004983- Issue #1303614: don't expose object's __dict__ when the dict is
Georg Brandl21e99f42010-03-07 15:23:59 +00004984 inherited from a built-in base.

Vinay Sajip8549ce32007-05-06 17:53:37 +00004986- When __slots__ are set to a unicode string, make it work the same as
Neal Norwitzcbd9ee62007-04-14 05:25:50 +00004987 setting a plain string, ie don't expand to single letter identifiers.
4988
Raymond Hettinger13936692007-04-11 18:40:58 +00004989- Request #1191699: Slices can now be pickled.
4990
Raymond Hettinger4db5fe92007-04-12 04:10:00 +00004991- Request #1193128: str.translate() now allows a None argument for
4992 translations that only remove characters without re-mapping the
4993 remaining characters.
4994
Georg Brandl5cb76c12007-03-21 09:00:39 +00004995- Patch #1682205: a TypeError while unpacking an iterable is no longer
4996 masked by a generic one with the message "unpack non-sequence".
4997
Neal Norwitzaa754b72007-03-21 06:39:48 +00004998- Remove unused file Python/fmod.c.
4999
Guido van Rossum143b5642007-03-23 04:58:42 +00005000- Bug #1683368: The object.__init__() and object.__new__() methods are
5001 now stricter in rejecting excess arguments. The only time when
5002 either allows excess arguments is when it is not overridden and the
5003 other one is. For backwards compatibility, when both are
5004 overridden, it is a deprecation warning (for now; maybe a Py3k
Guido van Rossum234b1ff2007-03-23 19:39:01 +00005005 warning later). Also, type.__init__() insists on the same signature
5006 as supported by type.__new__().

Georg Brandl3ee81df2008-05-17 18:14:43 +00005008- Patch #1675423: PyComplex_AsCComplex() now tries to convert an
5009 object to complex using its __complex__() method before falling back
5010 to the __float__() method. Therefore, the functions in the cmath
5011 module now can operate on objects that define a __complex__()

Gregory P. Smithbde4ae42008-01-17 08:35:49 +00005984 that the SMTP.starttls() caller no longer needs to call ehlo()
5985 beforehand. SMTP.starttls() now raises an exception of the server
Georg Brandl3ee81df2008-05-17 18:14:43 +00005986 does not claim to support starttls. Adds the
5987 SMTP.ehlo_or_helo_if_needed() method. Patch contributed by Bill
5988 Fenner.

6068 complex, tuple, list, dict, set, and frozenset. Formerly, it would
6069 silently miscode subclasses of those types. Now, it raises a
6070 ValueError instead.
Raymond Hettinger12e94202007-11-07 01:13:09 +00006071

Georg Brandl3ee81df2008-05-17 18:14:43 +00006086 time so that opening a database previously created with the DB_DUP
6087 or DB_DUPSORT flag set will keep the proper behavior on subsequent
6088 opens. Specifically: dictionary assignment to a DB object will
6089 replace all values for a given key when the database allows
6090 duplicate values. DB users should use DB.put(k, v) when they want
6091 to store duplicates; not DB[k] = v.
Gregory P. Smithec10a4a2007-11-05 02:32:26 +00006092

6098 characters with ASCII value less than 32. Also, it correctly quotes
6099 dots only if they occur on a single line, as opposed to the previous
6100 behavior of quoting dots if they are the second character of any
6101 line.
Georg Brandl4aef7272007-03-13 22:49:43 +00006102
