Georg Brandlfee0f442010-05-22 21:26:21 +0000614- Issue #8567: Fix precedence of signals in Decimal module: when a Decimal
615 operation raises multiple signals and more than one of those signals is

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

Georg Brandlfee0f442010-05-22 21:26:21 +0000858- Issue #7279: Comparisons involving a Decimal signaling NaN now signal
859 InvalidOperation instead of returning False. (Comparisons involving a quiet
860 NaN are unchanged.) Also, Decimal quiet NaNs are now hashable; Decimal
861 signaling NaNs remain unhashable.

Georg Brandlfee0f442010-05-22 21:26:21 +0000863- Issue #2531: Comparison operations between floats and Decimal instances now
864 return a result based on the numeric values of the operands; previously they
865 returned an arbitrary result based on the relative ordering of id(float) and
866 id(Decimal).

Barry Warsawf7f2d6f2010-03-31 21:07:16 +0000868- Issue #8233: When run as a script, py_compile.py optionally takes a single
Georg Brandlfee0f442010-05-22 21:26:21 +0000869 argument `-` which tells it to read files to compile from stdin. Each line is
870 read on demand and the named file is compiled immediately. (Original patch by
871 Piotr Ożarowski).

Georg Brandlfee0f442010-05-22 21:26:21 +0000880- Comparisons using one of <, <=, >, >= between a complex instance and a
881 Fractions instance now raise TypeError instead of returning True/False. This
882 makes Fraction <=> complex comparisons consistent with int <=> complex, float
883 <=> complex, and complex <=> complex comparisons.

992 the set of integer codes for which it was used differed between native packing
993 and standard packing.)

1318 encoded string for them. This ensures that the upload and register commands
1319 send the correct values to PyPI without any error.

1395
Georg Brandlba83f822010-03-14 09:50:54 +00001396- The ``__complex__()`` method is now looked up on the class of instances to
1397 make it consistent with other special methods.

1401
Mark Dickinson1b34d252010-01-01 17:27:30 +00001402- Issue #5080: A number of functions and methods previously produced a
Georg Brandlba83f822010-03-14 09:50:54 +00001403 DeprecationWarning when passed a float argument where an integer was expected.
1404 These functions and methods now raise TypeError instead. The majority of the
1405 effects of this change are in the extension modules, but some core functions
1406 and methods are affected: notably the 'chr', 'range' and 'xrange' builtins,
1407 and many unicode/str methods.

1421 of integers: the result of a/b is now correctly rounded for ints a and b (at
1422 least on IEEE 754 platforms), and in particular does not depend on the
1423 internal representation of a long.

Georg Brandlba83f822010-03-14 09:50:54 +00001569- Issue #7419: ``locale.setlocale()`` could crash the interpreter on Windows
1570 when called with invalid values.
Amaury Forgeot d'Arcd7288712009-12-01 21:51:04 +00001571
Georg Brandlba83f822010-03-14 09:50:54 +00001572- Issue #3382: 'F' formatting for float and complex now convert the result to
1573 upper case. This only affects 'inf' and 'nan', since 'f' no longer converts
1574 to 'g' for large values.
Amaury Forgeot d'Arcd7288712009-12-01 21:51:04 +00001575
Georg Brandlba83f822010-03-14 09:50:54 +00001576- Remove switch from "%f" formatting to "%g" formatting for floats larger than
1577 1e50 in absolute value.
Mark Dickinson9dd5e162009-11-23 20:54:09 +00001578
Georg Brandlba83f822010-03-14 09:50:54 +00001579- Remove restrictions on precision when formatting floats. E.g., "%.120g" %
1580 1e-100 used to raise OverflowError, but now gives the requested 120
1581 significant digits instead.
Mark Dickinson18cfada2009-11-23 18:46:41 +00001582
Georg Brandlba83f822010-03-14 09:50:54 +00001583- Add Py3k warnings for parameter names in parentheses.

Benjamin Peterson89b1a5c2009-11-19 22:58:01 +00001586
Georg Brandlba83f822010-03-14 09:50:54 +00001587- Issue #7085: Fix crash when importing some extensions in a thread on MacOSX
1588 10.6.
Ronald Oussoren315cd0c2009-11-19 16:25:21 +00001589
Georg Brandlba83f822010-03-14 09:50:54 +00001590- Issue #7117: ``repr(x)`` for a float x returns a result based on the shortest
1591 decimal string that's guaranteed to round back to x under correct rounding
1592 (with round-half-to-even rounding mode). Previously it gave a string based on
1593 rounding x to 17 decimal digits. repr(x) for a complex number behaves
1594 similarly. On platforms where the correctly-rounded strtod and dtoa code is
1595 not supported (see below), repr is unchanged.
Mark Dickinsonb678de82009-11-19 18:41:49 +00001596
Georg Brandlba83f822010-03-14 09:50:54 +00001597- Issue #7117: On almost all platforms: float-to-string and string-to-float
1598 conversions within Python are now correctly rounded. Places these conversions
1599 occur include: str for floats and complex numbers; the float and complex
1600 constructors; old-style and new-style numeric formatting; serialization and
1601 deserialization of floats and complex numbers using marshal, pickle and json;
1602 parsing of float and imaginary literals in Python code; Decimal-to-float
1603 conversion.
Mark Dickinsonb678de82009-11-19 18:41:49 +00001604
Georg Brandlba83f822010-03-14 09:50:54 +00001605 The conversions use a Python-adapted version of David Gay's well-known dtoa.c,
1606 providing correctly-rounded strtod and dtoa C functions. This code is
1607 supported on Windows, and on Unix-like platforms using gcc, icc or suncc as
1608 the C compiler. There may be a small number of platforms on which correct
1609 operation of this code cannot be guaranteed, so the code is not used: notably,
1610 this applies to platforms where the C double format is not IEEE 754 binary64,
1611 and to platforms on x86 hardware where the x87 FPU is set to 64-bit precision
1612 and Python's configure script is unable to determine how to change the FPU
1613 precision. On these platforms conversions use the platform strtod and dtoa,
1614 as before.
Mark Dickinsonb678de82009-11-19 18:41:49 +00001615
Georg Brandlba83f822010-03-14 09:50:54 +00001616- Issue #7117: Backport round implementation from Python 3.x. ``round()`` now
1617 uses the correctly-rounded string <-> float conversions described above (when
1618 available), and so produces correctly rounded results that will display nicely
1619 under the float repr. There are two related small changes: (1) round now
1620 accepts any class with an ``__index__()`` method for its second argument (but
1621 no longer accepts floats for the second argument), and (2) an excessively
1622 large second integer argument (e.g., ``round(1.234, 10**100)``) no longer
1623 raises an exception.

Philip Jenveyfab8be22009-11-17 02:42:26 +00001625- Issue #1757126: Fix the cyrillic-asian alias for the ptcp154 encoding.
1626
Georg Brandlba83f822010-03-14 09:50:54 +00001627- Fix several issues with ``compile()``. The input can now contain Windows and
1628 Mac newlines and is no longer required to end in a newline.
Benjamin Petersone36199b2009-11-12 23:39:44 +00001629

Amaury Forgeot d'Arcd0052d12009-10-06 19:56:32 +00001658- Issue #1571184: The Unicode database contains properties for more characters.
1659 The tables for code points representing numeric values, white spaces or line
1660 breaks are now generated from the official Unicode Character Database files,
1661 and include information from the Unihan.txt file.

1772 but with at least one decimal point and with a default precision
1773 of 12. Previously, the behavior the same but with a default precision of 6.
1774 This more closely matches ``str()``, and reduces surprises when adding

3409 ``printf`` function, whereas PyString_FromFormat has an independent
3410 implementation and uses "%zd" on all platforms for size_t values.
3411 This makes a difference on win64, where ``printf`` needs "%Id" to display
3412 64bit values.

Benjamin Peterson97179b02008-09-09 20:55:01 +00003414- Issue #3634: _weakref.ref(Exception).__init__() gave invalid return value on
3415 error.
3416
Amaury Forgeot d'Arcd3ffb892008-09-09 07:24:30 +00003417- Issue #3777: long() applied to a float object now always return a long
3418 object; previously an int would be returned for small values. the __long__
3419 method is allowed to return either an int or a long, but the behaviour of
3420 float objects should not change to respect backward compatibility.
3421
Amaury Forgeot d'Arc3571fbf2008-09-01 19:52:00 +00003422- Issue #3751: str.rpartition would perform a left-partition when called with
3423 a unicode argument.
3424
Benjamin Peterson17f03ca2008-09-01 14:18:30 +00003425- Issue #3683: Fix compilation when --without-threads is given.

Antoine Pitroud4ae97b2008-08-29 18:39:48 +00003427- Issue #3668: Fix a memory leak with the "s*" argument parser in
Vinay Sajip35e3b032008-09-01 14:33:59 +00003428 PyArg_ParseTuple and friends, which occurred when the argument for "s*"
Antoine Pitroud4ae97b2008-08-29 18:39:48 +00003429 was correctly parsed but parsing of subsequent arguments failed.
3430
Vinay Sajip35e3b032008-09-01 14:33:59 +00003431- Issue #2534: speed up isinstance() and issubclass() by 50-70%, so as to
Antoine Pitrou0668c622008-08-26 22:42:08 +00003432 match Python 2.5 speed despite the __instancecheck__ / __subclasscheck__
3433 mechanism. In the process, fix a bug where isinstance() and issubclass(),
3434 when given a tuple of classes as second argument, were looking up
3435 __instancecheck__ / __subclasscheck__ on the tuple rather than on each
3436 type object.
3437
Neal Norwitz18aa3882008-08-24 05:04:52 +00003438- Fix crashes on memory allocation failure found with failmalloc.

Brett Cannon1eaf0742008-09-02 01:25:16 +00003507 warnings.catch_warnings() along with some API cleanup. Expanding the tests
3508 for catch_warnings() also led to an improvement in the raising of a
3509 DeprecationWarning related to warnings.warn_explicit().
3510
Benjamin Peterson973e6c22008-09-01 23:12:58 +00003511- The deprecation warnings for the old camelCase threading API were removed.

3536 without limit.
3537
Benjamin Peterson37346b22008-08-23 20:27:43 +00003538- Issue #3643: Added a few more checks to _testcapi to prevent segfaults by

Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00003575What's New in Python 2.6 beta 3?
3576================================
3577
Barry Warsaw07a4a382008-08-21 01:15:08 +00003578*Release date: 20-Aug-2008*
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00003579
3580Core and Builtins
3581-----------------
3582
Guido van Rossumf8402962008-08-20 15:01:50 +00003583- Issue #1878: Remove Py_TPFLAGS_HAVE_VERSION_TAG from
3584 Py_TPFLAGS_DEFAULT when not building the core. This means 3rd party
3585 extensions do not automatically benefit from the class attribute
3586 cache; they will have to explicitly add Py_TPFLAGS_HAVE_VERSION_TAG
3587 to their tp_flags field if they care. This is a backwards
3588 compatibility feature; in 3.0, all types will use the cache by
3589 default.
3590
Benjamin Petersonf647dc12008-08-20 01:27:30 +00003591- Keyword arguments can now follow starred arguments. (``f(a, *args,
3592 keyword=23)`` is now valid syntax.)
3593
Thomas Heller0ad5ae02008-08-19 19:25:04 +00003594- ctypes function pointers that are COM methods have a boolean True
3595 value again.
3596
Martin v. Löwisf91d46a2008-08-12 14:49:50 +00003597- Issue #3139: Make buffer-interface thread-safe wrt. PyArg_ParseTuple,
3598 by denying s# to parse objects that have a releasebuffer procedure,
3599 and introducing s*.
3600
Georg Brandl1e13ea92008-08-11 09:07:59 +00003601- Issue #3537: Fix an assertion failure when an empty but presized dict
3602 object was stored in the freelist.
3603
Mark Dickinsonb6467572008-08-04 21:30:09 +00003604- Issue #1481296: Make long(float('nan')) and int(float('nan')) raise
3605 ValueError consistently across platforms.
3606
Amaury Forgeot d'Arc39fd6722008-07-31 21:28:03 +00003607- Issue #3479: On platforms where sizeof(int) is smaller than sizeof(long)
3608 (64bit Unix, for example), unichr() would truncate its argument and return
3609 u'\x00' for unichr(2**32). Now it properly raises an OverflowError.
3610
Neal Norwitze7d8be82008-07-31 17:17:14 +00003611- Apply security patches from Apple.
3612
Amaury Forgeot d'Arc246daed2008-07-31 00:42:16 +00003613- Issue #2542: Now that issubclass() may call arbitrary code, ensure that
3614 PyErr_ExceptionMatches returns 0 when an exception occurs there.
3615
Antoine Pitrou92f82162008-07-25 22:22:08 +00003616- Issue #1819: function calls with several named parameters are now on
3617 average 35% faster (as measured by pybench).
3618
Amaury Forgeot d'Arce4921fe2008-07-21 22:00:38 +00003619- Issue #2378: An unexpected UnboundLocalError or NameError could appear when
3620 the python debugger steps into a class statement: the free variables (local
3621 variables defined in an outer scope) would be deleted from the outer scope.
3622
Gregory P. Smith0470bab2008-07-22 04:46:32 +00003623- Issue #2620: Overflow checking when allocating or reallocating memory
3624 was not always being done properly in some python types and extension
3625 modules. PyMem_MALLOC, PyMem_REALLOC, PyMem_NEW and PyMem_RESIZE have
3626 all been updated to perform better checks and places in the code that
3627 would previously leak memory on the error path when such an allocation
3628 failed have been fixed.

3632
Hirokazu Yamamoto838c79f2008-08-20 13:14:07 +00003633- Issue #3612: Added some missing basic types in ctypes.wintypes.
3634
Benjamin Petersone977ad42008-08-20 01:42:01 +00003635- The methods ``is_in_tuple()``, ``is_vararg()``, and ``is_keywordarg()`` of
3636 symtable.Symbol have been deprecated for removal in 3.0 and the next release.
3637
Amaury Forgeot d'Arc351ffb82008-08-18 19:23:47 +00003638- Issue #2234: distutils failed for some versions of the cygwin compiler. The
3639 version reported by these tools does not necessarily follow the python
3640 version numbering scheme, so the module is less strict when parsing it.
3641
Nick Coghlanf70385a2008-08-18 12:42:46 +00003642- Issue #2235: Added Py3k warnings for types which will become unhashable
3643 under the stricter __hash__ inheritance rules in 3.0. Several types
3644 which did not meet the rules for hash invariants and were already
3645 unhashable in 3.0 have now been explicitly flagged as unhashable in
3646 2.6 as well (collections.Mapping, collections.Set, unittest.TestSuite,
3647 xml.dom.minidom.NamedNodeMap, numbers.Number, UserList.UserList)
3648
Brett Cannon88f801d2008-08-18 00:46:22 +00003649- Update __all__ for cookielib, csv, os, urllib2, and weakref to include things

3657
Hirokazu Yamamoto41a81eb2008-08-17 13:10:46 +00003658- Issue #3575: Incremental decoder's decode function now takes bytearray
3659 by using 's*' instead of 't#'.
3660
Mark Dickinson3e4caeb2009-02-21 20:27:01 +00003661- Issue #2222: Fixed reference leak when occurred os.rename()
Hirokazu Yamamoto7f30a682008-08-17 09:46:56 +00003662 fails unicode conversion on 2nd parameter. (windows only)
3663
Georg Brandl222e2082010-08-01 22:27:39 +00003664- Issue #2464: urllib2 now supports a malformation in the URL received
Facundo Batista94f243a2008-08-17 03:38:39 +00003665 in a redirect.
3666

Brett Cannon721b1452008-08-16 22:00:27 +00003668 BaseHTTPServer, cgi (and rfc822), httplib.
Brett Cannonabe423e2008-08-16 21:47:07 +00003669
Facundo Batistaeb90b782008-08-16 14:44:07 +00003670- Issue #2776: fixed small issue when handling an URL with double slash
3671 after a 302 response in the case of not going through a proxy.
3672
Antoine Pitroub90a8be2008-08-15 21:03:21 +00003673- Issue #2676: in the email package, content-type parsing was hanging on
3674 pathological input because of quadratic or exponential behaviour of a
3675 regular expression.
3676
Antoine Pitrou11ec65d2008-08-14 21:04:30 +00003677- Issue #3476: binary buffered reading through the new "io" library is now
3678 thread-safe.
3679
Brett Cannonbf3157b2008-08-14 05:00:03 +00003680- Silence the DeprecationWarning of rfc822 when it is imported by mimetools
3681 since mimetools itself is deprecated. Because modules are cached, all
3682 subsequent imports of rfc822 will not raise a visible DeprecationWarning.
3683
Antoine Pitrou9fcd4b32008-08-11 17:21:36 +00003684- Issue #3134: shutil referenced undefined WindowsError symbol.
3685
Robert Schuppenies14646332008-08-10 11:01:53 +00003686- Issue #1342811: Fix leak in Tkinter.Menu.delete. Commands associated to
3687 menu entries were not deleted.
3688
Brett Cannon83e81842008-08-09 23:30:55 +00003689- Copied the implementation of reduce() to _functools.reduce() to have a
3690 version that did not raise a DeprecationWarning under -3.
3691
Antoine Pitrou76b8bee2008-08-09 17:27:23 +00003692- Issue #3205: When iterating over a BZ2File fails allocating memory, raise
3693 a MemoryError rather than silently stop the iteration.

Antoine Pitroude781a42008-08-09 12:43:23 +00003718 asking for a specific length. This problem only affected files opened

3762
Nick Coghlan2a0c2b12008-08-04 12:47:17 +00003763- Issue #643841: The language reference now provides more detailed

3775-----------------
3776
Georg Brandl3e483f62008-07-16 22:57:41 +00003777- Issue #3156: Fix inconsistent behavior of the bytearray type: all
3778 its methods now allow for items objects that can be converted to
3779 an integer using operator.index().
3780
Mark Dickinson64b7e502008-07-16 09:40:03 +00003781- Issue #3360: Fix incorrect parsing of '020000000000.0', which
3782 produced a ValueError instead of giving the correct float.
3783
Eric Smitha5fa5a22008-07-16 00:11:49 +00003784- Issue #3083: Add alternate (#) formatting for bin, oct, hex output
3785 for str.format(). This adds the prefix 0b, 0o, or 0x, respectively.
3786
Mark Dickinson7103aa42008-07-15 19:08:33 +00003787- Issue #3008: the float type has a new instance method 'float.hex'
3788 and a new class method 'float.fromhex' to convert floating-point
3789 numbers to and from hexadecimal strings, respectively.
3790
Nick Coghlan6d6bd442008-07-15 15:40:22 +00003791- Issue #2235: __hash__ is once again inherited by default. To allow
3792 collections.Hashable to remain meaningful in the presence of the
3793 default hash implementation (object.__hash__), it is now possible
3794 to explicit block inheritance of hash by setting __hash__=None at
3795 the Python level, or tp_hash=PyObject_HashNotImplemented at the C
3796 level.
3797
Nick Coghlanb028f502008-07-13 14:52:36 +00003798- Issue #3221: Issue a RuntimeWarning instead of raising SystemError if
3799 the parent module cannot be found while performing an absolute import.
3800 This means that an incorrectly defined __package__ attribute will
3801 now only prevent relative imports in that module rather than causing
3802 all imports from that module to fail.
3803
Nick Coghlan14ff9942008-07-08 14:21:42 +00003804- Issue #2517: Allow unicode messages in Exceptions again by correctly

3814 another thread's dictionary.
3815
Mark Dickinson1ec2fcd2008-06-20 14:53:43 +00003816- Issue #3004: Minor change to slice.indices(): the start and stop
3817 arguments are now treated identically, making the behaviour easier
3818 to describe and understand. For example, slice(None, -10,
3819 1).indices(9) now returns (0, 0, 1) instead of (0, -1, 1), and
3820 slice(None, 10, -1).indices(10) returns (9, 9, -1) instead of (9,
3821 10, -1).
3822
Georg Brandl278fc502008-07-19 12:46:12 +00003823- Issue #3219: Calling a function with repeated keyword arguments,
3824 f(a=2, a=23), would not cause a syntax error. This was a regression
3825 from 2.4 caused by the switch to the new compiler.

Georg Brandl278fc502008-07-19 12:46:12 +00003827- Issue #2862: Make int and float freelist management consistent with
3828 other freelists. Changes their CompactFreeList apis into

3835 api functions without holding the GIL, which could lead to a fatal
3836 error when they failed.
3837
Martin v. Löwisaabf4042008-08-02 07:20:25 +00003838- Issue #799428: Fix Tkinter.Misc._nametowidget to unwrap Tcl command objects.

Amaury Forgeot d'Arc0f7cddc2008-07-06 21:34:39 +00003863- Issue #839496: SimpleHTTPServer used to open text files in text mode. This is
3864 both unnecessary (HTTP allows text content to be sent in several forms) and
Andrew M. Kuchlingcc3f2b12008-07-10 14:43:31 +00003865 wrong because the actual transmitted size could differ from the
Amaury Forgeot d'Arc0f7cddc2008-07-06 21:34:39 +00003866 content-length. The problem had been corrected in the 2.4 branch, but never
3867 merged into trunk.

Nick Coghlanc060b0e2008-07-02 13:09:19 +00003882- Issue #3190: Pydoc now hides the automatic module attribute __package__ (the

4270
Brett Cannonb61d8012008-05-11 23:39:04 +00004271- ``Lib/lib-old`` is now added to sys.path.
4272
Ronald Oussoren5640ce22008-06-05 12:58:24 +00004273- On MacOS X it is now possible to install the framework in 64-bit
4274 mode or even as a 4-way universal binary (that is, PPC, i386,
Georg Brandl5cc774e2008-06-11 20:28:06 +00004275 PPC64 and x86_64 support in one binary).
Ronald Oussoren5640ce22008-06-05 12:58:24 +00004276
4277 This is controlled by the configure argument ``--with-universal-archs``:
4278
4279 - ``--with-universal-archs=all``: install 4-way universal
4280
4281 - ``--with-universal-archs=32-bit``: install 2-way universal, 32-bit (the default)
4282
4283 - ``--with-universal-archs=64-bit``: install 2-way universal, 64-bit
4284
4285 This option should be used in combination with ``--enable-universalsdk=``.
4286
4287 NOTE: 64-bit and 4-way builds are only suppported on Mac OS X 10.5 (or later).

Christian Heimes7a990612008-05-26 13:15:11 +00004296
4297- The PyString functions have been renamed to PyBytes. A batch of
4298 defines were added so that the linker still sees the original
4299 PyString names.

Georg Brandl3ee81df2008-05-17 18:14:43 +00004337- Issue #1631171: Re-implement the 'warnings' module in C (the
4338 original Python code has been kept as backup). This will allow for
4339 using the 'warning's machinery in such places as the parser where
4340 use of pure Python code is not possible. Both the ``showarning()``
4341 and ``formatwarning()`` gain an optional 'line' argument which is
4342 not called by default for backwards-compatibility reasons. Setting
4343 ``warnings.showwarning()`` to an implementation that lacks support
4344 for the ``line`` argument will raise a DeprecationWarning.

4368
Gregory P. Smithd59fefb2008-04-22 08:11:33 +00004369- The getpass module has been improved on Unix. It now uses /dev/tty
4370 by default and uses stderr instead of stdout. A GetPassWarning is
4371 issued when input echo cannot be controlled.
Gregory P. Smith41e30182008-04-21 21:31:08 +00004372

Georg Brandl3ee81df2008-05-17 18:14:43 +00004386- Issue #2513: distutils on Windows is now capable of cross-compiling
Mark Hammond495cf992008-04-07 01:53:39 +00004387 extension modules between 32 and 64 bit platforms. See the distutls

4400 so the controlled environment will more closely mirror the typical
4401 script environment. This supports setup.py scripts that refer to
4402 data files.

Georg Brandl3ee81df2008-05-17 18:14:43 +00004407- Issue #2550: The approach used by client/server code for obtaining
4408 ports to listen on in network-oriented tests has been refined in an
4409 effort to facilitate running multiple instances of the entire
4410 regression test suite in parallel without issue.
4411 test_support.bind_port() has been fixed such that it will always
4412 return a unique port -- which wasn't always the case with the
4413 previous implementation, especially if socket options had been set
4414 that affected address reuse (i.e. SO_REUSEADDR, SO_REUSEPORT). The
4415 new implementation of bind_port() will actually raise an exception
4416 if it is passed an AF_INET/SOCK_STREAM socket with either the
4417 SO_REUSEADDR or SO_REUSEPORT socket option set. Furthermore, if
4418 available, bind_port() will set the SO_EXCLUSIVEADDRUSE option on
4419 the socket it's been passed. This currently only applies to
4420 Windows. This option prevents any other sockets from binding to the
4421 host/port we've bound to, thus removing the possibility of the
4422 'non-deterministic' behaviour, as Microsoft puts it, that occurs
4423 when a second SOCK_STREAM socket binds and accepts to a host/port
4424 that's already been bound by another socket. The optional preferred
4425 port parameter to bind_port() has been removed. Under no
4426 circumstances should tests be hard coding ports!
4427
4428 test_support.find_unused_port() has also been introduced, which will
4429 pass a temporary socket object to bind_port() in order to obtain an
4430 unused port. The temporary socket object is then closed and
4431 deleted, and the port is returned. This method should only be used
4432 for obtaining an unused port in order to pass to an external program
4433 (i.e. the -accept [port] argument to openssl's s_server mode) or as
4434 a parameter to a server-oriented class that doesn't give you direct
4435 access to the underlying socket used.
4436
4437 Finally, test_support.HOST has been introduced, which should be used
4438 for the host argument of any relevant socket calls (i.e. bind and
4439 connect).
Trent Nelsone41b0062008-04-08 23:47:30 +00004440
4441 The following tests were updated to following the new conventions:
Georg Brandl3ee81df2008-05-17 18:14:43 +00004442 test_socket, test_smtplib, test_asyncore, test_ssl, test_httplib,
Trent Nelsone41b0062008-04-08 23:47:30 +00004443 test_poplib, test_ftplib, test_telnetlib, test_socketserver,
4444 test_asynchat and test_socket_ssl.
4445
Georg Brandl3ee81df2008-05-17 18:14:43 +00004446 It is now possible for multiple instances of the regression test
4447 suite to run in parallel without issue.

Eric Smitha73fbe72008-02-23 03:09:44 +00004726- Added the future_builtins module, which contains hex() and oct().
4727 These are the PEP 3127 version of these functions, designed to be
4728 compatible with the hex() and oct() builtins from Python 3.0. They
4729 differ slightly in their output formats from the existing, unchanged
4730 Python 2.6 builtins. The expected usage of the future_builtins
4731 module is:
4732 from future_builtins import hex, oct
4733
Eric Smith7ef40bf2008-02-20 23:34:22 +00004734- Issue #1600: Modifed PyOS_ascii_formatd to use at most 2 digit
4735 exponents for exponents with absolute value < 100. Follows C99
4736 standard. This is a change on Windows, which would use 3 digits.
4737 Also, added 'n' to the formats that PyOS_ascii_formatd understands,
4738 so that any alterations it does to the resulting string will be
4739 available in stringlib/formatter.h (for float.__format__).
4740
Eric Smith5a3c1352008-02-19 13:21:56 +00004741- Implemented PEP 3101, Advanced String Formatting. This adds a new
4742 builtin format(); a format() method for str and unicode; a
4743 __format__() method to object, str, unicode, int, long, float, and
4744 datetime; the class string.Formatter; and the C API
4745 PyObject_Format().
4746
Georg Brandl3ee81df2008-05-17 18:14:43 +00004747- Fixed several potential crashes, all caused by specially crafted
4748 __del__ methods exploiting objects in temporarily inconsistent
4749 state.

4759 in order to allow pymalloc to free more arenas. Python may give back
4760 memory to the OS earlier.
Christian Heimes3b718a72008-02-14 12:47:33 +00004761
Georg Brandl3ee81df2008-05-17 18:14:43 +00004762- Issue #2045: Fix an infinite recursion triggered when printing a
4763 subclass of collections.defaultdict, if its default_factory is set
4764 to a bound method.
Amaury Forgeot d'Arcb01aa432008-02-08 00:56:02 +00004765
Christian Heimesf75dbef2008-02-08 00:11:31 +00004766- Fixed a minor memory leak in dictobject.c. The content of the free
4767 list was not freed on interpreter shutdown.
4768
Georg Brandl21e99f42010-03-07 15:23:59 +00004769- Limit free list of method and built-in function objects to 256

4773 functions ``PyInt_CompactFreeList`` and ``PyFloat_CompactFreeList``
Christian Heimes422051a2008-02-04 18:00:12 +00004774 to compact the internal free lists of pre-allocted ints and floats.
4775
Georg Brandl3ee81df2008-05-17 18:14:43 +00004776- Issue #1983: Fixed return type of fork(), fork1() and forkpty()
4777 calls. Python expected the return type int but the fork familie

Georg Brandl3ee81df2008-05-17 18:14:43 +00004789- Added ``PyType_ClearCache()`` and ``sys._clear_type_cache`` to clear
4790 the internal lookup cache for ref leak tests.
Christian Heimes908caac2008-01-27 23:34:59 +00004791
Georg Brandl3ee81df2008-05-17 18:14:43 +00004792- Patch #1473257: generator objects gain a gi_code attribute. This is
4793 the same object as the func_code attribute of the function that
4794 produced the generator.
Georg Brandl0cdf9a32008-01-26 14:14:20 +00004795
Georg Brandl3ee81df2008-05-17 18:14:43 +00004796- Issue #1920: "while 0" statements were completely removed by the
4797 compiler, even in the presence of an "else" clause, which is
4798 supposed to be run when the condition is false. Now the compiler
4799 correctly emits bytecode for the "else" suite.
Amaury Forgeot d'Arc31eaafe2008-01-24 22:59:25 +00004800
Guido van Rossumeead05f2008-01-24 18:21:02 +00004801- A few crashers fixed: weakref_in_del.py (issue #1377858);
4802 loosing_dict_ref.py (issue #1303614, test67.py);
4803 borrowed_ref_[34].py (not in tracker).
4804
Vinay Sajipd7cf32e2008-01-24 12:43:33 +00004805- Issue #1069410: The "can't load dll" message box on Windows is
Christian Heimesb2302ba2008-01-23 17:15:06 +00004806 suppressed while an extension is loaded by calling SetErrorMode in
4807 dynload_win.c. The error is still reported properly.
4808
Georg Brandl3ee81df2008-05-17 18:14:43 +00004809- Issue #1915: Python compiles with --enable-unicode=no again. However
Christian Heimes082c9b02008-01-23 14:20:50 +00004810 several extension methods and modules do not work without unicode
4811 support.
4812
Georg Brandl26543b12008-01-21 18:36:51 +00004813- Issue #1882: when compiling code from a string, encoding cookies in the
4814 second line of code were not always recognized correctly.
4815
Georg Brandl14404b62008-01-19 19:27:05 +00004816- Issue #1679: "0x" was taken as a valid integer literal.
4817
Georg Brandl6caad7d2008-01-26 14:19:22 +00004818- Issue #1865: ``bytes`` as an alias for ``str`` and b"" as an alias "" were
Christian Heimes288e89a2008-01-18 18:24:07 +00004819 added.
4820
Christian Heimesc94e2b52008-01-14 04:13:37 +00004821- sys.float_info / PyFloat_GetInfo: The floating point information
4822 object was converted from a dict to a specialized structseq object.
4823
Georg Brandl3ee81df2008-05-17 18:14:43 +00004824- Patch #1816: Added sys.flags structseq. It exposes the status of
4825 most command line arguments and PYTHON* environment variables.
Christian Heimesf31b69f2008-01-14 03:42:48 +00004826
Georg Brandl3ee81df2008-05-17 18:14:43 +00004827- Objects/structseq.c: Implemented new structseq representation. The
4828 patch makes structseqs (e.g. the return value of os.stat) more
4829 readable.
Christian Heimes9c201962008-01-14 03:33:52 +00004830
Georg Brandl3ee81df2008-05-17 18:14:43 +00004831- Patch #1700288: added a type attribute cache that caches method
4832 accesses, resulting in speedups in heavily object-oriented code.
Amaury Forgeot d'Arce4c270c2008-01-14 00:29:41 +00004833
Neal Norwitz3fc15b82008-01-10 05:42:58 +00004834- Bug #1776: __import__() no longer accepts filenames on any platform.
4835 The first parameter to __import__() must be a valid module name.
Christian Heimes3403f152008-01-09 19:56:33 +00004836
Georg Brandlaed6c662008-01-07 17:25:53 +00004837- Patch #1668: renamed THREADDEBUG envvar to PYTHONTHREADDEBUG.
4838
Georg Brandl3ee81df2008-05-17 18:14:43 +00004839- Patch #602345: Add -B command line option, PYTHONDONTWRITEBYTECODE
4840 envvar and sys.dont_write_bytecode attribute. All these can be set
4841 to forbid Python to attempt to write compiled bytecode files.
Georg Brandl2da0fce2008-01-07 17:09:35 +00004842
Georg Brandl3ee81df2008-05-17 18:14:43 +00004843- Improve some exception messages when Windows fails to load an
4844 extension module. Now we get for example '%1 is not a valid Win32
4845 application' instead of 'error code 193'.

Christian Heimes0a8143f2007-12-18 23:22:54 +00004852- Issue #1635: Platform independent creation and representation of NaN
Georg Brandl3ee81df2008-05-17 18:14:43 +00004853 and INF. float("nan"), float("inf") and float("-inf") now work on
4854 every platform with IEEE 754 semantics.
Christian Heimes0a8143f2007-12-18 23:22:54 +00004855
Georg Brandl3ee81df2008-05-17 18:14:43 +00004856- Compiler now generates simpler and faster code for dictionary
4857 literals. The oparg for BUILD_MAP now indicates an estimated
4858 dictionary size. There is a new opcode, STORE_MAP, for adding
4859 entries to the dictionary.

Georg Brandl3ee81df2008-05-17 18:14:43 +00004888- Patch #1739468: Directories and zipfiles containing a __main__.py
4889 file can now be directly executed by passing their name to the
4890 interpreter. The directory/zipfile is automatically inserted as the
4891 first entry in sys.path.
Nick Coghlan327a39b2007-11-18 11:56:28 +00004892
Georg Brandl3ee81df2008-05-17 18:14:43 +00004893- Issue #1265: Fix a problem with sys.settrace, if the tracing
4894 function uses a generator expression when at the same time the
4895 executed code is closing a paused generator.
Amaury Forgeot d'Arc0d75f092007-11-13 21:54:28 +00004896
Raymond Hettinger1760c8a2007-11-08 02:52:43 +00004897- sets and frozensets now have an isdisjoint() method.
4898
Raymond Hettinger3f8caa32007-10-24 01:28:33 +00004899- optimize the performance of builtin.sum().
4900
Neal Norwitz44f326e2007-10-05 05:29:17 +00004901- Fix warnings found by the new version of the Coverity checker.
4902
Georg Brandl21e99f42010-03-07 15:23:59 +00004903- The enumerate() built-in function is no longer bounded to sequences
Georg Brandl3ee81df2008-05-17 18:14:43 +00004904 smaller than LONG_MAX. Formerly, it raised an OverflowError. Now,
4905 automatically shifts from ints to longs.
Raymond Hettinger8f669372007-10-03 21:18:11 +00004906
Georg Brandl3ee81df2008-05-17 18:14:43 +00004907- Issue #1686386: Tuple's tp_repr did not take into account the
4908 possibility of having a self-referential tuple, which is possible
4909 from C code. Nor did object's tp_str consider that a type's tp_str
4910 could do something that could lead to an inifinite recursion.
4911 Py_ReprEnter() and Py_EnterRecursiveCall(), respectively, fixed the
4912 issues.
Brett Cannon0b14f242007-09-30 19:45:10 +00004913
Georg Brandl3ee81df2008-05-17 18:14:43 +00004914- Issue #1164: It was possible to trigger deadlock when using the
4915 'print' statement to write to a file since the GIL was not released
4916 as needed. Now PyObject_Print() does the right thing along with
4917 various tp_print implementations of the built-in types and those in
4918 the collections module.
Brett Cannon01531592007-09-17 03:28:34 +00004919
Georg Brandl3ee81df2008-05-17 18:14:43 +00004920- Issue #1147: Exceptions were directly allowing string exceptions in
4921 their throw() method even though string exceptions no longer
4922 allowed.
Brett Cannon4c20bc42007-09-11 21:02:28 +00004923
Georg Brandl3ee81df2008-05-17 18:14:43 +00004924- Issue #1096: Prevent a segfault from getting the repr of a very
4925 deeply nested list by using the recursion counter.
Brett Cannona0c05512007-09-10 21:38:27 +00004926
Brett Cannon1e534b52007-09-07 04:18:30 +00004927- Issue #1202533: Fix infinite recursion calls triggered by calls to
Georg Brandl3ee81df2008-05-17 18:14:43 +00004928 PyObject_Call() never calling back out to Python code to trigger
4929 recursion depth updates/checks. Required the creation of a static
4930 RuntimeError instance in case normalizing an exception put the
4931 recursion check value past its limit. Fixes crashers
4932 infinite_rec_(1|2|4|5).py.
Brett Cannon1e534b52007-09-07 04:18:30 +00004933
Georg Brandl3ee81df2008-05-17 18:14:43 +00004934- Patch #1031213: Decode source line in SyntaxErrors back to its

Neal Norwitz0ac60192007-05-27 04:08:54 +00004947- Add new attribute names for function objects. All the func_* become
Georg Brandl3ee81df2008-05-17 18:14:43 +00004948 __*__ attributes. (Some already existed, e.g., __doc__ and
4949 __name__.)
Neal Norwitz0ac60192007-05-27 04:08:54 +00004950
Neal Norwitz8b2bfbc2007-05-23 06:35:32 +00004951- Add -3 option to the interpreter to warn about features that are
4952 deprecated and will be changed/removed in Python 3.0.
4953
Georg Brandl2134e752007-05-21 20:34:16 +00004954- Patch #1686487: you can now pass any mapping after '**' in function
4955 calls.
4956
Collin Winter62903052007-05-18 23:11:24 +00004957- except clauses may now be spelled either "except E, target:" or
Georg Brandl3ee81df2008-05-17 18:14:43 +00004958 "except E as target:". This is to provide forwards compatibility
4959 with Python 3.0.
Collin Winter62903052007-05-18 23:11:24 +00004960
Brett Cannon229cee22007-05-05 01:34:02 +00004961- Deprecate BaseException.message as per PEP 352.
4962
Georg Brandl3ee81df2008-05-17 18:14:43 +00004963- Issue #1303614: don't expose object's __dict__ when the dict is
Georg Brandl21e99f42010-03-07 15:23:59 +00004964 inherited from a built-in base.
Armin Rigo9790a272007-05-02 19:23:31 +00004965
Vinay Sajip8549ce32007-05-06 17:53:37 +00004966- When __slots__ are set to a unicode string, make it work the same as
Neal Norwitzcbd9ee62007-04-14 05:25:50 +00004967 setting a plain string, ie don't expand to single letter identifiers.
4968
Raymond Hettinger13936692007-04-11 18:40:58 +00004969- Request #1191699: Slices can now be pickled.
4970
Raymond Hettinger4db5fe92007-04-12 04:10:00 +00004971- Request #1193128: str.translate() now allows a None argument for
4972 translations that only remove characters without re-mapping the
4973 remaining characters.
4974
Georg Brandl5cb76c12007-03-21 09:00:39 +00004975- Patch #1682205: a TypeError while unpacking an iterable is no longer
4976 masked by a generic one with the message "unpack non-sequence".
4977
Neal Norwitzaa754b72007-03-21 06:39:48 +00004978- Remove unused file Python/fmod.c.
4979
Guido van Rossum143b5642007-03-23 04:58:42 +00004980- Bug #1683368: The object.__init__() and object.__new__() methods are
4981 now stricter in rejecting excess arguments. The only time when
4982 either allows excess arguments is when it is not overridden and the
4983 other one is. For backwards compatibility, when both are
4984 overridden, it is a deprecation warning (for now; maybe a Py3k
Guido van Rossum234b1ff2007-03-23 19:39:01 +00004985 warning later). Also, type.__init__() insists on the same signature
4986 as supported by type.__new__().
Guido van Rossum143b5642007-03-23 04:58:42 +00004987
Georg Brandl3ee81df2008-05-17 18:14:43 +00004988- Patch #1675423: PyComplex_AsCComplex() now tries to convert an
4989 object to complex using its __complex__() method before falling back
4990 to the __float__() method. Therefore, the functions in the cmath
4991 module now can operate on objects that define a __complex__()
4992 method.

Georg Brandl3ee81df2008-05-17 18:14:43 +00004994- Patch #1623563: allow __class__ assignment for classes with
4995 __slots__. The old and the new class are still required to have the
4996 same slot names.

5009
Georg Brandl7b9c5552007-03-12 14:30:05 +00005010- Bug #1678647: write a newline after printing an exception in any
5011 case, even when converting the value to a string failed.
5012
Georg Brandl871f1bc2007-03-12 13:17:36 +00005013- The dir() function has been extended to call the __dir__() method on
Georg Brandl3ee81df2008-05-17 18:14:43 +00005014 its argument, if it exists. If not, it will work like before. This
5015 allows customizing the output of dir() in the presence of a
5016 __getattr__().

Georg Brandl4e933132006-09-06 20:05:58 +00005131- Bug #1542051: Exceptions now correctly call PyObject_GC_UnTrack.

Georg Brandl3ee81df2008-05-17 18:14:43 +00005149 generator expressions (x for x, in ... ) works again. Fixing this
5150 problem required changing the .pyc magic number. This means that

Facundo Batistad918a652007-04-24 13:54:38 +00005539- As specified in RFC 2616, an HTTP response like 2xx indicates that
Georg Brandl3ee81df2008-05-17 18:14:43 +00005540 the client's request was successfully received, understood, and

Georg Brandl3ee81df2008-05-17 18:14:43 +00005581 AttributeError instead of an IOError when the server's response

5673 TestCase and TestSuite subclasses (not instances) are no longer

Georg Brandl3ee81df2008-05-17 18:14:43 +00006066 time so that opening a database previously created with the DB_DUP
6067 or DB_DUPSORT flag set will keep the proper behavior on subsequent
6068 opens. Specifically: dictionary assignment to a DB object will
6069 replace all values for a given key when the database allows
6070 duplicate values. DB users should use DB.put(k, v) when they want
6071 to store duplicates; not DB[k] = v.

6078 characters with ASCII value less than 32. Also, it correctly quotes
6079 dots only if they occur on a single line, as opposed to the previous
6080 behavior of quoting dots if they are the second character of any
6081 line.
