Ezio Melottiab2eb0e2010-06-05 19:21:32 +0000415- Issue #8271: during the decoding of an invalid UTF-8 byte sequence, only the
416 start byte and the continuation byte(s) are now considered invalid, instead
417 of the number of bytes specified by the start byte.
418 E.g.: '\xf1\x80AB'.decode('utf-8', 'replace') now returns u'\ufffdAB' and
419 replaces with U+FFFD only the start byte ('\xf1') and the continuation byte
420 ('\x80') even if '\xf1' is the start byte of a 4-bytes sequence.
421 Previous versions returned a single u'\ufffd'.

Mark Dickinson4ca7c3c2010-05-30 13:18:10 +0000429- Issue #8748: Fix two issues with comparisons between complex and integer
430 objects. (1) The comparison could incorrectly return True in some cases
431 (2**53+1 == complex(2**53) == 2**53), breaking transivity of equality.
432 (2) The comparison raised an OverflowError for large integers, leading
433 to unpredictable exceptions when combining integers and complex objects
434 in sets or dicts.

Mark Dickinson81336372010-05-30 12:12:25 +0000436- Issue #5211: Implicit coercion for the complex type is now completely
437 removed. (Coercion for arithmetic operations was already removed in 2.7

817 with a non-empty format string. This is an effort to future-proof user
818 code. If a derived class does not currently implement __format__ but later
819 adds its own __format__, it would most likely break user code that had
820 supplied a format string. This will be changed to a DeprecationWaring in
821 Python 3.3 and it will be an error in Python 3.4.

873 NaN are unchanged.) Also, Decimal quiet NaNs are now hashable; Decimal
874 signaling NaNs remain unhashable.

878 returned an arbitrary result based on the relative ordering of id(float) and
879 id(Decimal).

883 read on demand and the named file is compiled immediately. (Original patch by

Georg Brandlfee0f442010-05-22 21:26:21 +0000893- Comparisons using one of <, <=, >, >= between a complex instance and a
894 Fractions instance now raise TypeError instead of returning True/False. This
895 makes Fraction <=> complex comparisons consistent with int <=> complex, float
896 <=> complex, and complex <=> complex comparisons.

Georg Brandlba83f822010-03-14 09:50:54 +00001314- Issue #7610: Reworked implementation of the internal ``zipfile.ZipExtFile``
1315 class used to represent files stored inside an archive. The new
1316 implementation is significantly faster and can be wrapped in a
1317 ``io.BufferedReader`` object for more speedups. It also solves an issue
1318 where interleaved calls to ``read()`` and ``readline()`` give wrong results.

1408
Georg Brandlba83f822010-03-14 09:50:54 +00001409- The ``__complex__()`` method is now looked up on the class of instances to
1410 make it consistent with other special methods.

1414
Mark Dickinson1b34d252010-01-01 17:27:30 +00001415- Issue #5080: A number of functions and methods previously produced a
Georg Brandlba83f822010-03-14 09:50:54 +00001416 DeprecationWarning when passed a float argument where an integer was expected.
1417 These functions and methods now raise TypeError instead. The majority of the
1418 effects of this change are in the extension modules, but some core functions
1419 and methods are affected: notably the 'chr', 'range' and 'xrange' builtins,
1420 and many unicode/str methods.

1435 least on IEEE 754 platforms), and in particular does not depend on the
1436 internal representation of a long.

Georg Brandlba83f822010-03-14 09:50:54 +00001585- Issue #3382: 'F' formatting for float and complex now convert the result to
1586 upper case. This only affects 'inf' and 'nan', since 'f' no longer converts
1587 to 'g' for large values.
Amaury Forgeot d'Arcd7288712009-12-01 21:51:04 +00001588
Georg Brandlba83f822010-03-14 09:50:54 +00001589- Remove switch from "%f" formatting to "%g" formatting for floats larger than
1590 1e50 in absolute value.
Mark Dickinson9dd5e162009-11-23 20:54:09 +00001591
Georg Brandlba83f822010-03-14 09:50:54 +00001592- Remove restrictions on precision when formatting floats. E.g., "%.120g" %
1593 1e-100 used to raise OverflowError, but now gives the requested 120
1594 significant digits instead.

1601 10.6.
Ronald Oussoren315cd0c2009-11-19 16:25:21 +00001602
Georg Brandlba83f822010-03-14 09:50:54 +00001603- Issue #7117: ``repr(x)`` for a float x returns a result based on the shortest
1604 decimal string that's guaranteed to round back to x under correct rounding
1605 (with round-half-to-even rounding mode). Previously it gave a string based on
1606 rounding x to 17 decimal digits. repr(x) for a complex number behaves
1607 similarly. On platforms where the correctly-rounded strtod and dtoa code is
1608 not supported (see below), repr is unchanged.
Mark Dickinsonb678de82009-11-19 18:41:49 +00001609
Georg Brandlba83f822010-03-14 09:50:54 +00001610- Issue #7117: On almost all platforms: float-to-string and string-to-float
1611 conversions within Python are now correctly rounded. Places these conversions
1612 occur include: str for floats and complex numbers; the float and complex
1613 constructors; old-style and new-style numeric formatting; serialization and
1614 deserialization of floats and complex numbers using marshal, pickle and json;
1615 parsing of float and imaginary literals in Python code; Decimal-to-float
1616 conversion.
Mark Dickinsonb678de82009-11-19 18:41:49 +00001617
Georg Brandlba83f822010-03-14 09:50:54 +00001618 The conversions use a Python-adapted version of David Gay's well-known dtoa.c,
1619 providing correctly-rounded strtod and dtoa C functions. This code is
1620 supported on Windows, and on Unix-like platforms using gcc, icc or suncc as
1621 the C compiler. There may be a small number of platforms on which correct
1622 operation of this code cannot be guaranteed, so the code is not used: notably,
1623 this applies to platforms where the C double format is not IEEE 754 binary64,
1624 and to platforms on x86 hardware where the x87 FPU is set to 64-bit precision
1625 and Python's configure script is unable to determine how to change the FPU
1626 precision. On these platforms conversions use the platform strtod and dtoa,
1627 as before.
Mark Dickinsonb678de82009-11-19 18:41:49 +00001628
Georg Brandlba83f822010-03-14 09:50:54 +00001629- Issue #7117: Backport round implementation from Python 3.x. ``round()`` now
1630 uses the correctly-rounded string <-> float conversions described above (when
1631 available), and so produces correctly rounded results that will display nicely
1632 under the float repr. There are two related small changes: (1) round now
1633 accepts any class with an ``__index__()`` method for its second argument (but
1634 no longer accepts floats for the second argument), and (2) an excessively
1635 large second integer argument (e.g., ``round(1.234, 10**100)``) no longer
1636 raises an exception.

1639
Georg Brandlba83f822010-03-14 09:50:54 +00001640- Fix several issues with ``compile()``. The input can now contain Windows and
1641 Mac newlines and is no longer required to end in a newline.

1787 This more closely matches ``str()``, and reduces surprises when adding
1788 alignment flags to the empty presentation type. This also affects the new
1789 complex.__format__ in the same way.

2020 eventual KeyError would always report the empty ``frozenset()`` as the missing

3416
Martin v. Löwis9fa5a282008-09-11 06:53:30 +00003417- Issue #3642: Suppress warning in obmalloc when size_t is larger than uint.
3418
Amaury Forgeot d'Arc05e34492008-09-10 22:04:45 +00003419- Issue #3743: In a few places, PY_FORMAT_SIZE_T was incorrectly used with
3420 PyString_FromFormat or PyErr_Format to display size_t values. The macro
3421 PY_FORMAT_SIZE_T is designed to select the correct format for the OS
3422 ``printf`` function, whereas PyString_FromFormat has an independent
3423 implementation and uses "%zd" on all platforms for size_t values.
3424 This makes a difference on win64, where ``printf`` needs "%Id" to display
3425 64bit values.
3426
Benjamin Peterson97179b02008-09-09 20:55:01 +00003427- Issue #3634: _weakref.ref(Exception).__init__() gave invalid return value on
3428 error.
3429
Amaury Forgeot d'Arcd3ffb892008-09-09 07:24:30 +00003430- Issue #3777: long() applied to a float object now always return a long
3431 object; previously an int would be returned for small values. the __long__
3432 method is allowed to return either an int or a long, but the behaviour of
3433 float objects should not change to respect backward compatibility.
3434
Amaury Forgeot d'Arc3571fbf2008-09-01 19:52:00 +00003435- Issue #3751: str.rpartition would perform a left-partition when called with
3436 a unicode argument.
3437
Benjamin Peterson17f03ca2008-09-01 14:18:30 +00003438- Issue #3683: Fix compilation when --without-threads is given.
3439
Antoine Pitroud4ae97b2008-08-29 18:39:48 +00003440- Issue #3668: Fix a memory leak with the "s*" argument parser in
Vinay Sajip35e3b032008-09-01 14:33:59 +00003441 PyArg_ParseTuple and friends, which occurred when the argument for "s*"
Antoine Pitroud4ae97b2008-08-29 18:39:48 +00003442 was correctly parsed but parsing of subsequent arguments failed.
3443
Vinay Sajip35e3b032008-09-01 14:33:59 +00003444- Issue #2534: speed up isinstance() and issubclass() by 50-70%, so as to
Antoine Pitrou0668c622008-08-26 22:42:08 +00003445 match Python 2.5 speed despite the __instancecheck__ / __subclasscheck__
3446 mechanism. In the process, fix a bug where isinstance() and issubclass(),
3447 when given a tuple of classes as second argument, were looking up
3448 __instancecheck__ / __subclasscheck__ on the tuple rather than on each
3449 type object.
3450
Neal Norwitz18aa3882008-08-24 05:04:52 +00003451- Fix crashes on memory allocation failure found with failmalloc.
3452
3453- Fix memory leaks found with valgrind and update suppressions file.
3454
3455- Fix compiler warnings in opt mode which would lead to invalid memory reads.
3456
3457- Fix problem using wrong name in decimal module reported by pychecker.
3458
Christian Heimes7d4c3172008-08-22 19:47:25 +00003459- Silenced another compiler warning about a used but not defined
3460 function 'stringlib_contains_obj'.
3461
Benjamin Peterson712ee922008-08-24 18:10:20 +00003462- Added warnings on the use of ``__getslice__``, ``__setslice__``, or
3463 ``__delslice__``.
3464
Gregory P. Smith2bb25cc2008-09-02 05:29:51 +00003465- Issue #3678: Correctly pass LDFLAGS and LDLAST to the linker on shared
3466 library targets in the Makefile.
3467
Gregory P. Smith980b99b2008-09-07 05:15:18 +00003468- Issue #1204: The configure script now tests for additional libraries
3469 that may be required when linking against readline. This fixes issues
3470 with x86_64 builds on some platforms (a few Linux flavors and OpenBSD).

Brett Cannon1eaf0742008-09-02 01:25:16 +00003520 warnings.catch_warnings() along with some API cleanup. Expanding the tests
3521 for catch_warnings() also led to an improvement in the raising of a
3522 DeprecationWarning related to warnings.warn_explicit().
3523
Benjamin Peterson973e6c22008-09-01 23:12:58 +00003524- The deprecation warnings for the old camelCase threading API were removed.

Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00003588What's New in Python 2.6 beta 3?
3589================================
3590
Barry Warsaw07a4a382008-08-21 01:15:08 +00003591*Release date: 20-Aug-2008*
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00003592
3593Core and Builtins
3594-----------------
3595
Guido van Rossumf8402962008-08-20 15:01:50 +00003596- Issue #1878: Remove Py_TPFLAGS_HAVE_VERSION_TAG from
3597 Py_TPFLAGS_DEFAULT when not building the core. This means 3rd party
3598 extensions do not automatically benefit from the class attribute
3599 cache; they will have to explicitly add Py_TPFLAGS_HAVE_VERSION_TAG
3600 to their tp_flags field if they care. This is a backwards
3601 compatibility feature; in 3.0, all types will use the cache by
3602 default.
3603
Benjamin Petersonf647dc12008-08-20 01:27:30 +00003604- Keyword arguments can now follow starred arguments. (``f(a, *args,
3605 keyword=23)`` is now valid syntax.)
3606
Thomas Heller0ad5ae02008-08-19 19:25:04 +00003607- ctypes function pointers that are COM methods have a boolean True
3608 value again.
3609
Martin v. Löwisf91d46a2008-08-12 14:49:50 +00003610- Issue #3139: Make buffer-interface thread-safe wrt. PyArg_ParseTuple,
3611 by denying s# to parse objects that have a releasebuffer procedure,
3612 and introducing s*.
3613
Georg Brandl1e13ea92008-08-11 09:07:59 +00003614- Issue #3537: Fix an assertion failure when an empty but presized dict
3615 object was stored in the freelist.
3616
Mark Dickinsonb6467572008-08-04 21:30:09 +00003617- Issue #1481296: Make long(float('nan')) and int(float('nan')) raise
3618 ValueError consistently across platforms.
3619
Amaury Forgeot d'Arc39fd6722008-07-31 21:28:03 +00003620- Issue #3479: On platforms where sizeof(int) is smaller than sizeof(long)
3621 (64bit Unix, for example), unichr() would truncate its argument and return
3622 u'\x00' for unichr(2**32). Now it properly raises an OverflowError.
3623
Neal Norwitze7d8be82008-07-31 17:17:14 +00003624- Apply security patches from Apple.
3625
Amaury Forgeot d'Arc246daed2008-07-31 00:42:16 +00003626- Issue #2542: Now that issubclass() may call arbitrary code, ensure that
3627 PyErr_ExceptionMatches returns 0 when an exception occurs there.
3628
Antoine Pitrou92f82162008-07-25 22:22:08 +00003629- Issue #1819: function calls with several named parameters are now on
3630 average 35% faster (as measured by pybench).
3631
Amaury Forgeot d'Arce4921fe2008-07-21 22:00:38 +00003632- Issue #2378: An unexpected UnboundLocalError or NameError could appear when
3633 the python debugger steps into a class statement: the free variables (local
3634 variables defined in an outer scope) would be deleted from the outer scope.
3635
Gregory P. Smith0470bab2008-07-22 04:46:32 +00003636- Issue #2620: Overflow checking when allocating or reallocating memory
3637 was not always being done properly in some python types and extension
3638 modules. PyMem_MALLOC, PyMem_REALLOC, PyMem_NEW and PyMem_RESIZE have
3639 all been updated to perform better checks and places in the code that
3640 would previously leak memory on the error path when such an allocation
3641 failed have been fixed.

3649 symtable.Symbol have been deprecated for removal in 3.0 and the next release.
3650
Amaury Forgeot d'Arc351ffb82008-08-18 19:23:47 +00003651- Issue #2234: distutils failed for some versions of the cygwin compiler. The
3652 version reported by these tools does not necessarily follow the python
3653 version numbering scheme, so the module is less strict when parsing it.
3654
Nick Coghlanf70385a2008-08-18 12:42:46 +00003655- Issue #2235: Added Py3k warnings for types which will become unhashable
3656 under the stricter __hash__ inheritance rules in 3.0. Several types
3657 which did not meet the rules for hash invariants and were already
3658 unhashable in 3.0 have now been explicitly flagged as unhashable in
3659 2.6 as well (collections.Mapping, collections.Set, unittest.TestSuite,
3660 xml.dom.minidom.NamedNodeMap, numbers.Number, UserList.UserList)
3661
Brett Cannon88f801d2008-08-18 00:46:22 +00003662- Update __all__ for cookielib, csv, os, urllib2, and weakref to include things
3663 imported into the module but exposed as part of the module's API.
3664

3670
Hirokazu Yamamoto41a81eb2008-08-17 13:10:46 +00003671- Issue #3575: Incremental decoder's decode function now takes bytearray
3672 by using 's*' instead of 't#'.
3673
Mark Dickinson3e4caeb2009-02-21 20:27:01 +00003674- Issue #2222: Fixed reference leak when occurred os.rename()
Hirokazu Yamamoto7f30a682008-08-17 09:46:56 +00003675 fails unicode conversion on 2nd parameter. (windows only)
3676
Georg Brandl222e2082010-08-01 22:27:39 +00003677- Issue #2464: urllib2 now supports a malformation in the URL received
Facundo Batista94f243a2008-08-17 03:38:39 +00003678 in a redirect.
3679

Brett Cannon721b1452008-08-16 22:00:27 +00003681 BaseHTTPServer, cgi (and rfc822), httplib.
Brett Cannonabe423e2008-08-16 21:47:07 +00003682
Facundo Batistaeb90b782008-08-16 14:44:07 +00003683- Issue #2776: fixed small issue when handling an URL with double slash
3684 after a 302 response in the case of not going through a proxy.
3685
Antoine Pitroub90a8be2008-08-15 21:03:21 +00003686- Issue #2676: in the email package, content-type parsing was hanging on
3687 pathological input because of quadratic or exponential behaviour of a
3688 regular expression.
3689
Antoine Pitrou11ec65d2008-08-14 21:04:30 +00003690- Issue #3476: binary buffered reading through the new "io" library is now

3694 since mimetools itself is deprecated. Because modules are cached, all
3695 subsequent imports of rfc822 will not raise a visible DeprecationWarning.

Antoine Pitroude781a42008-08-09 12:43:23 +00003731 asking for a specific length. This problem only affected files opened

3775
Nick Coghlan2a0c2b12008-08-04 12:47:17 +00003776- Issue #643841: The language reference now provides more detailed
3777 coverage of the lookup process for special methods. The disclaimers
3778 regarding lack of coverage of new-style classes have also been

3788-----------------
3789
Georg Brandl3e483f62008-07-16 22:57:41 +00003790- Issue #3156: Fix inconsistent behavior of the bytearray type: all
3791 its methods now allow for items objects that can be converted to
3792 an integer using operator.index().
3793
Mark Dickinson64b7e502008-07-16 09:40:03 +00003794- Issue #3360: Fix incorrect parsing of '020000000000.0', which
3795 produced a ValueError instead of giving the correct float.
3796
Eric Smitha5fa5a22008-07-16 00:11:49 +00003797- Issue #3083: Add alternate (#) formatting for bin, oct, hex output
3798 for str.format(). This adds the prefix 0b, 0o, or 0x, respectively.
3799
Mark Dickinson7103aa42008-07-15 19:08:33 +00003800- Issue #3008: the float type has a new instance method 'float.hex'
3801 and a new class method 'float.fromhex' to convert floating-point
3802 numbers to and from hexadecimal strings, respectively.
3803
Nick Coghlan6d6bd442008-07-15 15:40:22 +00003804- Issue #2235: __hash__ is once again inherited by default. To allow
3805 collections.Hashable to remain meaningful in the presence of the
3806 default hash implementation (object.__hash__), it is now possible
3807 to explicit block inheritance of hash by setting __hash__=None at
3808 the Python level, or tp_hash=PyObject_HashNotImplemented at the C
3809 level.
3810
Nick Coghlanb028f502008-07-13 14:52:36 +00003811- Issue #3221: Issue a RuntimeWarning instead of raising SystemError if
3812 the parent module cannot be found while performing an absolute import.
3813 This means that an incorrectly defined __package__ attribute will
3814 now only prevent relative imports in that module rather than causing
3815 all imports from that module to fail.
3816
Nick Coghlan14ff9942008-07-08 14:21:42 +00003817- Issue #2517: Allow unicode messages in Exceptions again by correctly
3818 bypassing the instance dictionary when looking up __unicode__ on
3819 new-style classes.

3826 threading.local: the first member set by a thread could be saved in
3827 another thread's dictionary.
3828
Mark Dickinson1ec2fcd2008-06-20 14:53:43 +00003829- Issue #3004: Minor change to slice.indices(): the start and stop
3830 arguments are now treated identically, making the behaviour easier
3831 to describe and understand. For example, slice(None, -10,
3832 1).indices(9) now returns (0, 0, 1) instead of (0, -1, 1), and
3833 slice(None, 10, -1).indices(10) returns (9, 9, -1) instead of (9,
3834 10, -1).
3835
Georg Brandl278fc502008-07-19 12:46:12 +00003836- Issue #3219: Calling a function with repeated keyword arguments,
3837 f(a=2, a=23), would not cause a syntax error. This was a regression
3838 from 2.4 caused by the switch to the new compiler.
Benjamin Peterson175e4d92008-07-01 19:34:52 +00003839
Georg Brandl278fc502008-07-19 12:46:12 +00003840- Issue #2862: Make int and float freelist management consistent with
3841 other freelists. Changes their CompactFreeList apis into

3848 api functions without holding the GIL, which could lead to a fatal
3849 error when they failed.
3850
Martin v. Löwisaabf4042008-08-02 07:20:25 +00003851- Issue #799428: Fix Tkinter.Misc._nametowidget to unwrap Tcl command objects.

Amaury Forgeot d'Arc0f7cddc2008-07-06 21:34:39 +00003876- Issue #839496: SimpleHTTPServer used to open text files in text mode. This is
3877 both unnecessary (HTTP allows text content to be sent in several forms) and
Andrew M. Kuchlingcc3f2b12008-07-10 14:43:31 +00003878 wrong because the actual transmitted size could differ from the
Amaury Forgeot d'Arc0f7cddc2008-07-06 21:34:39 +00003879 content-length. The problem had been corrected in the 2.4 branch, but never
3880 merged into trunk.

Nick Coghlanc060b0e2008-07-02 13:09:19 +00003895- Issue #3190: Pydoc now hides the automatic module attribute __package__ (the

3897
Brett Cannon8bb8fa52008-07-02 01:57:08 +00003898- Issue #2885 (partial): The urllib.urlopen() function has been deprecated for

Vinay Sajip9828b7e2008-06-17 11:04:02 +00004266- Library: on MacOS X you can now set ``ARCHFLAGS`` in the shell
Ronald Oussoren5640ce22008-06-05 12:58:24 +00004267 environment to control the '-arch' flags that are used to build
4268 an extension. This was added for compatibility with Apple's build
4269 of Python.
4270
4271- The bundled OSX-specific copy of libbffi is now in sync with the version
4272 shipped with PyObjC 2.0 and includes support for x86_64 and ppc64 platforms.
4273
Georg Brandl25c34082008-08-18 23:09:49 +00004274- The threading module gained aliases for names that will be removed in the

Brett Cannonb61d8012008-05-11 23:39:04 +00004284- ``Lib/lib-old`` is now added to sys.path.
4285
Ronald Oussoren5640ce22008-06-05 12:58:24 +00004286- On MacOS X it is now possible to install the framework in 64-bit
4287 mode or even as a 4-way universal binary (that is, PPC, i386,
Georg Brandl5cc774e2008-06-11 20:28:06 +00004288 PPC64 and x86_64 support in one binary).
Ronald Oussoren5640ce22008-06-05 12:58:24 +00004289
4290 This is controlled by the configure argument ``--with-universal-archs``:
4291
4292 - ``--with-universal-archs=all``: install 4-way universal
4293
4294 - ``--with-universal-archs=32-bit``: install 2-way universal, 32-bit (the default)
4295
4296 - ``--with-universal-archs=64-bit``: install 2-way universal, 64-bit
4297
4298 This option should be used in combination with ``--enable-universalsdk=``.
4299
4300 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 +00004350- Issue #1631171: Re-implement the 'warnings' module in C (the
4351 original Python code has been kept as backup). This will allow for
4352 using the 'warning's machinery in such places as the parser where
4353 use of pure Python code is not possible. Both the ``showarning()``
4354 and ``formatwarning()`` gain an optional 'line' argument which is
4355 not called by default for backwards-compatibility reasons. Setting
4356 ``warnings.showwarning()`` to an implementation that lacks support
4357 for the ``line`` argument will raise a DeprecationWarning.

Gregory P. Smithd59fefb2008-04-22 08:11:33 +00004382- The getpass module has been improved on Unix. It now uses /dev/tty
4383 by default and uses stderr instead of stdout. A GetPassWarning is
4384 issued when input echo cannot be controlled.

Georg Brandl3ee81df2008-05-17 18:14:43 +00004399- Issue #2513: distutils on Windows is now capable of cross-compiling
Mark Hammond495cf992008-04-07 01:53:39 +00004400 extension modules between 32 and 64 bit platforms. See the distutls

Georg Brandl3ee81df2008-05-17 18:14:43 +00004420- Issue #2550: The approach used by client/server code for obtaining
4421 ports to listen on in network-oriented tests has been refined in an
4422 effort to facilitate running multiple instances of the entire
4423 regression test suite in parallel without issue.
4424 test_support.bind_port() has been fixed such that it will always
4425 return a unique port -- which wasn't always the case with the
4426 previous implementation, especially if socket options had been set
4427 that affected address reuse (i.e. SO_REUSEADDR, SO_REUSEPORT). The
4428 new implementation of bind_port() will actually raise an exception
4429 if it is passed an AF_INET/SOCK_STREAM socket with either the
4430 SO_REUSEADDR or SO_REUSEPORT socket option set. Furthermore, if
4431 available, bind_port() will set the SO_EXCLUSIVEADDRUSE option on
4432 the socket it's been passed. This currently only applies to
4433 Windows. This option prevents any other sockets from binding to the
4434 host/port we've bound to, thus removing the possibility of the
4435 'non-deterministic' behaviour, as Microsoft puts it, that occurs
4436 when a second SOCK_STREAM socket binds and accepts to a host/port
4437 that's already been bound by another socket. The optional preferred
4438 port parameter to bind_port() has been removed. Under no
4439 circumstances should tests be hard coding ports!
4440
4441 test_support.find_unused_port() has also been introduced, which will
4442 pass a temporary socket object to bind_port() in order to obtain an
4443 unused port. The temporary socket object is then closed and
4444 deleted, and the port is returned. This method should only be used
4445 for obtaining an unused port in order to pass to an external program
4446 (i.e. the -accept [port] argument to openssl's s_server mode) or as
4447 a parameter to a server-oriented class that doesn't give you direct
4448 access to the underlying socket used.
4449
4450 Finally, test_support.HOST has been introduced, which should be used
4451 for the host argument of any relevant socket calls (i.e. bind and
4452 connect).
Trent Nelsone41b0062008-04-08 23:47:30 +00004453
4454 The following tests were updated to following the new conventions:
Georg Brandl3ee81df2008-05-17 18:14:43 +00004455 test_socket, test_smtplib, test_asyncore, test_ssl, test_httplib,
Trent Nelsone41b0062008-04-08 23:47:30 +00004456 test_poplib, test_ftplib, test_telnetlib, test_socketserver,
4457 test_asynchat and test_socket_ssl.
4458
Georg Brandl3ee81df2008-05-17 18:14:43 +00004459 It is now possible for multiple instances of the regression test
4460 suite to run in parallel without issue.

Eric Smitha73fbe72008-02-23 03:09:44 +00004739- Added the future_builtins module, which contains hex() and oct().
4740 These are the PEP 3127 version of these functions, designed to be
4741 compatible with the hex() and oct() builtins from Python 3.0. They
4742 differ slightly in their output formats from the existing, unchanged
4743 Python 2.6 builtins. The expected usage of the future_builtins
4744 module is:
4745 from future_builtins import hex, oct
4746
Eric Smith7ef40bf2008-02-20 23:34:22 +00004747- Issue #1600: Modifed PyOS_ascii_formatd to use at most 2 digit
4748 exponents for exponents with absolute value < 100. Follows C99
4749 standard. This is a change on Windows, which would use 3 digits.
4750 Also, added 'n' to the formats that PyOS_ascii_formatd understands,
4751 so that any alterations it does to the resulting string will be
4752 available in stringlib/formatter.h (for float.__format__).
4753
Eric Smith5a3c1352008-02-19 13:21:56 +00004754- Implemented PEP 3101, Advanced String Formatting. This adds a new
4755 builtin format(); a format() method for str and unicode; a
4756 __format__() method to object, str, unicode, int, long, float, and
4757 datetime; the class string.Formatter; and the C API
4758 PyObject_Format().
4759
Georg Brandl3ee81df2008-05-17 18:14:43 +00004760- Fixed several potential crashes, all caused by specially crafted
4761 __del__ methods exploiting objects in temporarily inconsistent
4762 state.

4766 a slot on a registered virtual subclass.

4772 in order to allow pymalloc to free more arenas. Python may give back
4773 memory to the OS earlier.
Christian Heimes3b718a72008-02-14 12:47:33 +00004774
Georg Brandl3ee81df2008-05-17 18:14:43 +00004775- Issue #2045: Fix an infinite recursion triggered when printing a
4776 subclass of collections.defaultdict, if its default_factory is set
4777 to a bound method.
Amaury Forgeot d'Arcb01aa432008-02-08 00:56:02 +00004778
Christian Heimesf75dbef2008-02-08 00:11:31 +00004779- Fixed a minor memory leak in dictobject.c. The content of the free
4780 list was not freed on interpreter shutdown.

Georg Brandl21e99f42010-03-07 15:23:59 +00004782- Limit free list of method and built-in function objects to 256
Georg Brandl3ee81df2008-05-17 18:14:43 +00004783 entries each.
Christian Heimes6075a822008-02-06 12:44:34 +00004784
Georg Brandl3ee81df2008-05-17 18:14:43 +00004785- Patch #1953: Added ``sys._compact_freelists()`` and the C API
4786 functions ``PyInt_CompactFreeList`` and ``PyFloat_CompactFreeList``
Christian Heimes422051a2008-02-04 18:00:12 +00004787 to compact the internal free lists of pre-allocted ints and floats.
4788
Georg Brandl3ee81df2008-05-17 18:14:43 +00004789- Issue #1983: Fixed return type of fork(), fork1() and forkpty()
4790 calls. Python expected the return type int but the fork familie
4791 returns pi_t.
Christian Heimes951cc0f2008-01-31 23:08:23 +00004792
Georg Brandl3ee81df2008-05-17 18:14:43 +00004793- Issue #1678380: Fix a bug that identifies 0j and -0j when they
4794 appear in the same code unit.
Mark Dickinson105be772008-01-31 22:17:37 +00004795

Georg Brandl3ee81df2008-05-17 18:14:43 +00004802- Added ``PyType_ClearCache()`` and ``sys._clear_type_cache`` to clear
4803 the internal lookup cache for ref leak tests.
Christian Heimes908caac2008-01-27 23:34:59 +00004804
Georg Brandl3ee81df2008-05-17 18:14:43 +00004805- Patch #1473257: generator objects gain a gi_code attribute. This is
4806 the same object as the func_code attribute of the function that
4807 produced the generator.
Georg Brandl0cdf9a32008-01-26 14:14:20 +00004808
Georg Brandl3ee81df2008-05-17 18:14:43 +00004809- Issue #1920: "while 0" statements were completely removed by the
4810 compiler, even in the presence of an "else" clause, which is
4811 supposed to be run when the condition is false. Now the compiler
4812 correctly emits bytecode for the "else" suite.
Amaury Forgeot d'Arc31eaafe2008-01-24 22:59:25 +00004813
Guido van Rossumeead05f2008-01-24 18:21:02 +00004814- A few crashers fixed: weakref_in_del.py (issue #1377858);
4815 loosing_dict_ref.py (issue #1303614, test67.py);
4816 borrowed_ref_[34].py (not in tracker).
4817
Vinay Sajipd7cf32e2008-01-24 12:43:33 +00004818- Issue #1069410: The "can't load dll" message box on Windows is
Christian Heimesb2302ba2008-01-23 17:15:06 +00004819 suppressed while an extension is loaded by calling SetErrorMode in
4820 dynload_win.c. The error is still reported properly.
4821
Georg Brandl3ee81df2008-05-17 18:14:43 +00004822- Issue #1915: Python compiles with --enable-unicode=no again. However
Christian Heimes082c9b02008-01-23 14:20:50 +00004823 several extension methods and modules do not work without unicode
4824 support.
4825
Georg Brandl26543b12008-01-21 18:36:51 +00004826- Issue #1882: when compiling code from a string, encoding cookies in the
4827 second line of code were not always recognized correctly.
4828
Georg Brandl14404b62008-01-19 19:27:05 +00004829- Issue #1679: "0x" was taken as a valid integer literal.
4830
Georg Brandl6caad7d2008-01-26 14:19:22 +00004831- Issue #1865: ``bytes`` as an alias for ``str`` and b"" as an alias "" were
Christian Heimes288e89a2008-01-18 18:24:07 +00004832 added.
4833
Christian Heimesc94e2b52008-01-14 04:13:37 +00004834- sys.float_info / PyFloat_GetInfo: The floating point information
4835 object was converted from a dict to a specialized structseq object.
4836
Georg Brandl3ee81df2008-05-17 18:14:43 +00004837- Patch #1816: Added sys.flags structseq. It exposes the status of
4838 most command line arguments and PYTHON* environment variables.
Christian Heimesf31b69f2008-01-14 03:42:48 +00004839
Georg Brandl3ee81df2008-05-17 18:14:43 +00004840- Objects/structseq.c: Implemented new structseq representation. The
4841 patch makes structseqs (e.g. the return value of os.stat) more
4842 readable.
Christian Heimes9c201962008-01-14 03:33:52 +00004843
Georg Brandl3ee81df2008-05-17 18:14:43 +00004844- Patch #1700288: added a type attribute cache that caches method
4845 accesses, resulting in speedups in heavily object-oriented code.
Amaury Forgeot d'Arce4c270c2008-01-14 00:29:41 +00004846
Neal Norwitz3fc15b82008-01-10 05:42:58 +00004847- Bug #1776: __import__() no longer accepts filenames on any platform.
4848 The first parameter to __import__() must be a valid module name.
Christian Heimes3403f152008-01-09 19:56:33 +00004849
Georg Brandlaed6c662008-01-07 17:25:53 +00004850- Patch #1668: renamed THREADDEBUG envvar to PYTHONTHREADDEBUG.
4851
Georg Brandl3ee81df2008-05-17 18:14:43 +00004852- Patch #602345: Add -B command line option, PYTHONDONTWRITEBYTECODE
4853 envvar and sys.dont_write_bytecode attribute. All these can be set
4854 to forbid Python to attempt to write compiled bytecode files.
Georg Brandl2da0fce2008-01-07 17:09:35 +00004855
Georg Brandl3ee81df2008-05-17 18:14:43 +00004856- Improve some exception messages when Windows fails to load an
4857 extension module. Now we get for example '%1 is not a valid Win32
4858 application' instead of 'error code 193'.
Amaury Forgeot d'Arce0b76952008-01-04 02:04:15 +00004859

4863 y) functions.
Christian Heimese2ca4242008-01-03 20:23:15 +00004864
Christian Heimes0a8143f2007-12-18 23:22:54 +00004865- Issue #1635: Platform independent creation and representation of NaN
Georg Brandl3ee81df2008-05-17 18:14:43 +00004866 and INF. float("nan"), float("inf") and float("-inf") now work on
4867 every platform with IEEE 754 semantics.
Christian Heimes0a8143f2007-12-18 23:22:54 +00004868
Georg Brandl3ee81df2008-05-17 18:14:43 +00004869- Compiler now generates simpler and faster code for dictionary
4870 literals. The oparg for BUILD_MAP now indicates an estimated
4871 dictionary size. There is a new opcode, STORE_MAP, for adding
4872 entries to the dictionary.

Andrew M. Kuchling395fe442007-12-05 13:27:20 +00004882- Issue #1553: An erroneous __length_hint__ can make list() raise a
Christian Heimes7cc1c6f2007-12-05 12:52:34 +00004883 SystemError.
4884
Nick Coghlanef01d822007-12-03 12:55:17 +00004885- PEP 366: Allow explicit relative imports when executing modules

Georg Brandl3ee81df2008-05-17 18:14:43 +00004901- Patch #1739468: Directories and zipfiles containing a __main__.py
4902 file can now be directly executed by passing their name to the
4903 interpreter. The directory/zipfile is automatically inserted as the
4904 first entry in sys.path.
Nick Coghlan327a39b2007-11-18 11:56:28 +00004905
Georg Brandl3ee81df2008-05-17 18:14:43 +00004906- Issue #1265: Fix a problem with sys.settrace, if the tracing
4907 function uses a generator expression when at the same time the
4908 executed code is closing a paused generator.
Amaury Forgeot d'Arc0d75f092007-11-13 21:54:28 +00004909
Raymond Hettinger1760c8a2007-11-08 02:52:43 +00004910- sets and frozensets now have an isdisjoint() method.
4911
Raymond Hettinger3f8caa32007-10-24 01:28:33 +00004912- optimize the performance of builtin.sum().
4913
Neal Norwitz44f326e2007-10-05 05:29:17 +00004914- Fix warnings found by the new version of the Coverity checker.
4915
Georg Brandl21e99f42010-03-07 15:23:59 +00004916- The enumerate() built-in function is no longer bounded to sequences
Georg Brandl3ee81df2008-05-17 18:14:43 +00004917 smaller than LONG_MAX. Formerly, it raised an OverflowError. Now,
4918 automatically shifts from ints to longs.
Raymond Hettinger8f669372007-10-03 21:18:11 +00004919
Georg Brandl3ee81df2008-05-17 18:14:43 +00004920- Issue #1686386: Tuple's tp_repr did not take into account the
4921 possibility of having a self-referential tuple, which is possible
4922 from C code. Nor did object's tp_str consider that a type's tp_str
4923 could do something that could lead to an inifinite recursion.
4924 Py_ReprEnter() and Py_EnterRecursiveCall(), respectively, fixed the
4925 issues.
Brett Cannon0b14f242007-09-30 19:45:10 +00004926
Georg Brandl3ee81df2008-05-17 18:14:43 +00004927- Issue #1164: It was possible to trigger deadlock when using the
4928 'print' statement to write to a file since the GIL was not released
4929 as needed. Now PyObject_Print() does the right thing along with
4930 various tp_print implementations of the built-in types and those in
4931 the collections module.
Brett Cannon01531592007-09-17 03:28:34 +00004932
Georg Brandl3ee81df2008-05-17 18:14:43 +00004933- Issue #1147: Exceptions were directly allowing string exceptions in
4934 their throw() method even though string exceptions no longer
4935 allowed.
Brett Cannon4c20bc42007-09-11 21:02:28 +00004936
Georg Brandl3ee81df2008-05-17 18:14:43 +00004937- Issue #1096: Prevent a segfault from getting the repr of a very
4938 deeply nested list by using the recursion counter.
Brett Cannona0c05512007-09-10 21:38:27 +00004939
Brett Cannon1e534b52007-09-07 04:18:30 +00004940- Issue #1202533: Fix infinite recursion calls triggered by calls to
Georg Brandl3ee81df2008-05-17 18:14:43 +00004941 PyObject_Call() never calling back out to Python code to trigger
4942 recursion depth updates/checks. Required the creation of a static
4943 RuntimeError instance in case normalizing an exception put the
4944 recursion check value past its limit. Fixes crashers
4945 infinite_rec_(1|2|4|5).py.
Brett Cannon1e534b52007-09-07 04:18:30 +00004946

Neal Norwitz0ac60192007-05-27 04:08:54 +00004960- Add new attribute names for function objects. All the func_* become
Georg Brandl3ee81df2008-05-17 18:14:43 +00004961 __*__ attributes. (Some already existed, e.g., __doc__ and
4962 __name__.)
Neal Norwitz0ac60192007-05-27 04:08:54 +00004963
Neal Norwitz8b2bfbc2007-05-23 06:35:32 +00004964- Add -3 option to the interpreter to warn about features that are
4965 deprecated and will be changed/removed in Python 3.0.
4966
Georg Brandl2134e752007-05-21 20:34:16 +00004967- Patch #1686487: you can now pass any mapping after '**' in function
4968 calls.
4969
Collin Winter62903052007-05-18 23:11:24 +00004970- except clauses may now be spelled either "except E, target:" or
Georg Brandl3ee81df2008-05-17 18:14:43 +00004971 "except E as target:". This is to provide forwards compatibility
4972 with Python 3.0.

Brett Cannon229cee22007-05-05 01:34:02 +00004974- Deprecate BaseException.message as per PEP 352.
4975
Georg Brandl3ee81df2008-05-17 18:14:43 +00004976- Issue #1303614: don't expose object's __dict__ when the dict is
Georg Brandl21e99f42010-03-07 15:23:59 +00004977 inherited from a built-in base.

Vinay Sajip8549ce32007-05-06 17:53:37 +00004979- When __slots__ are set to a unicode string, make it work the same as
Neal Norwitzcbd9ee62007-04-14 05:25:50 +00004980 setting a plain string, ie don't expand to single letter identifiers.
4981
Raymond Hettinger13936692007-04-11 18:40:58 +00004982- Request #1191699: Slices can now be pickled.
4983
Raymond Hettinger4db5fe92007-04-12 04:10:00 +00004984- Request #1193128: str.translate() now allows a None argument for
4985 translations that only remove characters without re-mapping the
4986 remaining characters.
4987
Georg Brandl5cb76c12007-03-21 09:00:39 +00004988- Patch #1682205: a TypeError while unpacking an iterable is no longer
4989 masked by a generic one with the message "unpack non-sequence".
4990
Neal Norwitzaa754b72007-03-21 06:39:48 +00004991- Remove unused file Python/fmod.c.
4992
Guido van Rossum143b5642007-03-23 04:58:42 +00004993- Bug #1683368: The object.__init__() and object.__new__() methods are
4994 now stricter in rejecting excess arguments. The only time when
4995 either allows excess arguments is when it is not overridden and the
4996 other one is. For backwards compatibility, when both are
4997 overridden, it is a deprecation warning (for now; maybe a Py3k
Guido van Rossum234b1ff2007-03-23 19:39:01 +00004998 warning later). Also, type.__init__() insists on the same signature
4999 as supported by type.__new__().

Georg Brandl3ee81df2008-05-17 18:14:43 +00005001- Patch #1675423: PyComplex_AsCComplex() now tries to convert an
5002 object to complex using its __complex__() method before falling back
5003 to the __float__() method. Therefore, the functions in the cmath
5004 module now can operate on objects that define a __complex__()
5005 method.

Georg Brandl3ee81df2008-05-17 18:14:43 +00006079 time so that opening a database previously created with the DB_DUP
6080 or DB_DUPSORT flag set will keep the proper behavior on subsequent
6081 opens. Specifically: dictionary assignment to a DB object will
6082 replace all values for a given key when the database allows
6083 duplicate values. DB users should use DB.put(k, v) when they want
6084 to store duplicates; not DB[k] = v.

6091 characters with ASCII value less than 32. Also, it correctly quotes
6092 dots only if they occur on a single line, as opposed to the previous
6093 behavior of quoting dots if they are the second character of any
6094 line.
