406 start byte and the continuation byte(s) are now considered invalid, instead
407 of the number of bytes specified by the start byte.
408 E.g.: '\xf1\x80AB'.decode('utf-8', 'replace') now returns u'\ufffdAB' and
409 replaces with U+FFFD only the start byte ('\xf1') and the continuation byte
410 ('\x80') even if '\xf1' is the start byte of a 4-bytes sequence.

421 (2**53+1 == complex(2**53) == 2**53), breaking transivity of equality.

Georg Brandlfee0f442010-05-22 21:26:21 +0000617- Issue #8567: Fix precedence of signals in Decimal module: when a Decimal
618 operation raises multiple signals and more than one of those signals is
619 trapped, the specification determines the order in which the signals should be

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

Mark Dickinson8a950712010-04-03 15:47:46 +0000846
847 >>> Decimal(1.1)
848 Decimal('1.100000000000000088817841970012523233890533447265625')

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

Georg Brandlfee0f442010-05-22 21:26:21 +0000866- Issue #2531: Comparison operations between floats and Decimal instances now
867 return a result based on the numeric values of the operands; previously they
868 returned an arbitrary result based on the relative ordering of id(float) and
869 id(Decimal).

Barry Warsawf7f2d6f2010-03-31 21:07:16 +0000871- Issue #8233: When run as a script, py_compile.py optionally takes a single
Georg Brandlfee0f442010-05-22 21:26:21 +0000872 argument `-` which tells it to read files to compile from stdin. Each line is
873 read on demand and the named file is compiled immediately. (Original patch by

Georg Brandlfee0f442010-05-22 21:26:21 +0000883- Comparisons using one of <, <=, >, >= between a complex instance and a
884 Fractions instance now raise TypeError instead of returning True/False. This
885 makes Fraction <=> complex comparisons consistent with int <=> complex, float
886 <=> complex, and complex <=> complex comparisons.

Georg Brandlfee0f442010-05-22 21:26:21 +0000993 produces a DeprecationWarning in this case. (In Python 2.6, the behaviour was
994 inconsistent: __int__ was used for some integer codes but not for others, and
995 the set of integer codes for which it was used differed between native packing
996 and standard packing.)

1301 position to the given argument, which goes against the tradition of

1305 class used to represent files stored inside an archive. The new
1306 implementation is significantly faster and can be wrapped in a

1398
Georg Brandlba83f822010-03-14 09:50:54 +00001399- The ``__complex__()`` method is now looked up on the class of instances to
1400 make it consistent with other special methods.

1404
Mark Dickinson1b34d252010-01-01 17:27:30 +00001405- Issue #5080: A number of functions and methods previously produced a
Georg Brandlba83f822010-03-14 09:50:54 +00001406 DeprecationWarning when passed a float argument where an integer was expected.
1407 These functions and methods now raise TypeError instead. The majority of the
1408 effects of this change are in the extension modules, but some core functions
1409 and methods are affected: notably the 'chr', 'range' and 'xrange' builtins,
1410 and many unicode/str methods.

1424 of integers: the result of a/b is now correctly rounded for ints a and b (at
1425 least on IEEE 754 platforms), and in particular does not depend on the
1426 internal representation of a long.

1434
Georg Brandlba83f822010-03-14 09:50:54 +00001435 These executables now work properly with the arch(1) command: ``arch -ppc

Georg Brandlba83f822010-03-14 09:50:54 +00001572- Issue #7419: ``locale.setlocale()`` could crash the interpreter on Windows
1573 when called with invalid values.

Georg Brandlba83f822010-03-14 09:50:54 +00001575- Issue #3382: 'F' formatting for float and complex now convert the result to
1576 upper case. This only affects 'inf' and 'nan', since 'f' no longer converts
1577 to 'g' for large values.
Amaury Forgeot d'Arcd7288712009-12-01 21:51:04 +00001578
Georg Brandlba83f822010-03-14 09:50:54 +00001579- Remove switch from "%f" formatting to "%g" formatting for floats larger than
1580 1e50 in absolute value.
Mark Dickinson9dd5e162009-11-23 20:54:09 +00001581
Georg Brandlba83f822010-03-14 09:50:54 +00001582- Remove restrictions on precision when formatting floats. E.g., "%.120g" %
1583 1e-100 used to raise OverflowError, but now gives the requested 120
1584 significant digits instead.
Mark Dickinson18cfada2009-11-23 18:46:41 +00001585
Georg Brandlba83f822010-03-14 09:50:54 +00001586- Add Py3k warnings for parameter names in parentheses.

Benjamin Peterson89b1a5c2009-11-19 22:58:01 +00001589
Georg Brandlba83f822010-03-14 09:50:54 +00001590- Issue #7085: Fix crash when importing some extensions in a thread on MacOSX
1591 10.6.
Ronald Oussoren315cd0c2009-11-19 16:25:21 +00001592
Georg Brandlba83f822010-03-14 09:50:54 +00001593- Issue #7117: ``repr(x)`` for a float x returns a result based on the shortest
1594 decimal string that's guaranteed to round back to x under correct rounding
1595 (with round-half-to-even rounding mode). Previously it gave a string based on
1596 rounding x to 17 decimal digits. repr(x) for a complex number behaves
1597 similarly. On platforms where the correctly-rounded strtod and dtoa code is
1598 not supported (see below), repr is unchanged.
Mark Dickinsonb678de82009-11-19 18:41:49 +00001599
Georg Brandlba83f822010-03-14 09:50:54 +00001600- Issue #7117: On almost all platforms: float-to-string and string-to-float
1601 conversions within Python are now correctly rounded. Places these conversions
1602 occur include: str for floats and complex numbers; the float and complex
1603 constructors; old-style and new-style numeric formatting; serialization and
1604 deserialization of floats and complex numbers using marshal, pickle and json;
1605 parsing of float and imaginary literals in Python code; Decimal-to-float
1606 conversion.
Mark Dickinsonb678de82009-11-19 18:41:49 +00001607
Georg Brandlba83f822010-03-14 09:50:54 +00001608 The conversions use a Python-adapted version of David Gay's well-known dtoa.c,
1609 providing correctly-rounded strtod and dtoa C functions. This code is
1610 supported on Windows, and on Unix-like platforms using gcc, icc or suncc as
1611 the C compiler. There may be a small number of platforms on which correct
1612 operation of this code cannot be guaranteed, so the code is not used: notably,
1613 this applies to platforms where the C double format is not IEEE 754 binary64,
1614 and to platforms on x86 hardware where the x87 FPU is set to 64-bit precision
1615 and Python's configure script is unable to determine how to change the FPU
1616 precision. On these platforms conversions use the platform strtod and dtoa,
1617 as before.
Mark Dickinsonb678de82009-11-19 18:41:49 +00001618
Georg Brandlba83f822010-03-14 09:50:54 +00001619- Issue #7117: Backport round implementation from Python 3.x. ``round()`` now
1620 uses the correctly-rounded string <-> float conversions described above (when
1621 available), and so produces correctly rounded results that will display nicely
1622 under the float repr. There are two related small changes: (1) round now
1623 accepts any class with an ``__index__()`` method for its second argument (but
1624 no longer accepts floats for the second argument), and (2) an excessively
1625 large second integer argument (e.g., ``round(1.234, 10**100)``) no longer
1626 raises an exception.

Philip Jenveyfab8be22009-11-17 02:42:26 +00001628- Issue #1757126: Fix the cyrillic-asian alias for the ptcp154 encoding.
1629
Georg Brandlba83f822010-03-14 09:50:54 +00001630- Fix several issues with ``compile()``. The input can now contain Windows and
1631 Mac newlines and is no longer required to end in a newline.
Benjamin Petersone36199b2009-11-12 23:39:44 +00001632

1662 The tables for code points representing numeric values, white spaces or line
1663 breaks are now generated from the official Unicode Character Database files,
1664 and include information from the Unihan.txt file.

1775 but with at least one decimal point and with a default precision
1776 of 12. Previously, the behavior the same but with a default precision of 6.
1777 This more closely matches ``str()``, and reduces surprises when adding

Georg Brandlba83f822010-03-14 09:50:54 +00001844 untrackable objects are not tracked by the garbage collector. This can reduce
1845 the size of collections and therefore the garbage collection overhead on
1846 long-running programs, depending on their particular use of datatypes.

1853 internal representation of integers, for performance reasons. Base 2**30 is
1854 enabled by default on 64-bit machines. Add --enable-big-digits option to
1855 configure, which overrides the default. Add sys.long_info structseq to

1887
Georg Brandl29c6a282009-04-05 20:23:13 +00001888- Issue #1242657: the __len__() and __length_hint__() calls in several tools
Raymond Hettingerb5163702009-02-02 21:50:13 +00001889 were suppressing all exceptions. These include list(), filter(), map(),

1891
Benjamin Peterson596d3062009-01-19 15:42:23 +00001892- os.ftruncate raises OSErrors instead of IOErrors for consistency with other os

Georg Brandlba83f822010-03-14 09:50:54 +00001919- Issue #1180193: When importing a module from a .pyc (or .pyo) file with an
1920 existing .py counterpart, override the co_filename attributes of all code
1921 objects if the original filename is obsolete (which can happen if the file has

3406
Martin v. Löwis9fa5a282008-09-11 06:53:30 +00003407- Issue #3642: Suppress warning in obmalloc when size_t is larger than uint.
3408
Amaury Forgeot d'Arc05e34492008-09-10 22:04:45 +00003409- Issue #3743: In a few places, PY_FORMAT_SIZE_T was incorrectly used with
3410 PyString_FromFormat or PyErr_Format to display size_t values. The macro
3411 PY_FORMAT_SIZE_T is designed to select the correct format for the OS
3412 ``printf`` function, whereas PyString_FromFormat has an independent
3413 implementation and uses "%zd" on all platforms for size_t values.
3414 This makes a difference on win64, where ``printf`` needs "%Id" to display
3415 64bit values.
3416
Benjamin Peterson97179b02008-09-09 20:55:01 +00003417- Issue #3634: _weakref.ref(Exception).__init__() gave invalid return value on
3418 error.
3419
Amaury Forgeot d'Arcd3ffb892008-09-09 07:24:30 +00003420- Issue #3777: long() applied to a float object now always return a long
3421 object; previously an int would be returned for small values. the __long__
3422 method is allowed to return either an int or a long, but the behaviour of
3423 float objects should not change to respect backward compatibility.
3424
Amaury Forgeot d'Arc3571fbf2008-09-01 19:52:00 +00003425- Issue #3751: str.rpartition would perform a left-partition when called with
3426 a unicode argument.
3427
Benjamin Peterson17f03ca2008-09-01 14:18:30 +00003428- Issue #3683: Fix compilation when --without-threads is given.
3429
Antoine Pitroud4ae97b2008-08-29 18:39:48 +00003430- Issue #3668: Fix a memory leak with the "s*" argument parser in
Vinay Sajip35e3b032008-09-01 14:33:59 +00003431 PyArg_ParseTuple and friends, which occurred when the argument for "s*"
Antoine Pitroud4ae97b2008-08-29 18:39:48 +00003432 was correctly parsed but parsing of subsequent arguments failed.
3433
Vinay Sajip35e3b032008-09-01 14:33:59 +00003434- Issue #2534: speed up isinstance() and issubclass() by 50-70%, so as to
Antoine Pitrou0668c622008-08-26 22:42:08 +00003435 match Python 2.5 speed despite the __instancecheck__ / __subclasscheck__
3436 mechanism. In the process, fix a bug where isinstance() and issubclass(),
3437 when given a tuple of classes as second argument, were looking up
3438 __instancecheck__ / __subclasscheck__ on the tuple rather than on each
3439 type object.
3440
Neal Norwitz18aa3882008-08-24 05:04:52 +00003441- Fix crashes on memory allocation failure found with failmalloc.
3442
3443- Fix memory leaks found with valgrind and update suppressions file.
3444
3445- Fix compiler warnings in opt mode which would lead to invalid memory reads.
3446
3447- Fix problem using wrong name in decimal module reported by pychecker.
3448
Christian Heimes7d4c3172008-08-22 19:47:25 +00003449- Silenced another compiler warning about a used but not defined
3450 function 'stringlib_contains_obj'.
3451
Benjamin Peterson712ee922008-08-24 18:10:20 +00003452- Added warnings on the use of ``__getslice__``, ``__setslice__``, or
3453 ``__delslice__``.
3454
Gregory P. Smith2bb25cc2008-09-02 05:29:51 +00003455- Issue #3678: Correctly pass LDFLAGS and LDLAST to the linker on shared
3456 library targets in the Makefile.
3457
Gregory P. Smith980b99b2008-09-07 05:15:18 +00003458- Issue #1204: The configure script now tests for additional libraries
3459 that may be required when linking against readline. This fixes issues
3460 with x86_64 builds on some platforms (a few Linux flavors and OpenBSD).
3461
Benjamin Peterson14cb6bc2008-08-26 17:08:40 +00003462C-API
3463-----
3464
3465- Aliased PyObject_Bytes to PyObject_Str.

3469
Amaury Forgeot d'Arc24cb3822008-09-11 20:56:13 +00003470- Issue #3640: Pickling a list or a dict uses less local variables, to reduce
3471 stack usage in the case of deeply nested objects.
3472
Guido van Rossume3c4fd92008-09-10 14:27:00 +00003473- Issue #3629: Fix sre "bytecode" validator for an end case.
3474
Martin v. Löwis24329ba2008-09-10 13:38:12 +00003475- Issue #3811: The Unicode database was updated to 5.1.
3476
Nick Coghland2e09382008-09-11 12:11:06 +00003477- Issue #3781: Further warnings.catch_warnings() cleanup to prevent
3478 silent misbehaviour when a single instance is nested in multiple
3479 with statements, or when the methods are invoked in the wrong order.
3480
Vinay Sajip844f7412008-09-09 13:42:08 +00003481- Issue #3809: Fixed spurious 'test.blah' file left behind by test_logging.
3482
Nick Coghland2e09382008-09-11 12:11:06 +00003483- Issue #3781: Clean up the API for warnings.catch_warnings() by having it
Brett Cannon672237d2008-09-09 00:49:16 +00003484 return a list or None rather than a custom object.
3485
Benjamin Peterson6ac7d7c2008-09-06 19:28:11 +00003486- Issue #1638033: Cookie.Morsel gained the httponly attribute.
3487
Antoine Pitrouebcd0ce2008-09-05 23:30:23 +00003488- Issue #3535: zipfile couldn't read some zip files larger than 2GB.
3489
3490- Issue #3776: Deprecate the bsddb package for removal in 3.0.
Brett Cannon32476fc2008-09-05 18:33:51 +00003491
Hirokazu Yamamoto42e459e2008-09-04 14:25:30 +00003492- Issue #3762: platform.architecture() fails if python is lanched via
3493 its symbolic link.
3494
Vinay Sajip65d66e12008-09-04 07:31:21 +00003495- Issue #3772: Fixed regression problem in StreamHandler.emit().

Facundo Batistac585df92008-09-03 22:35:50 +00003498 to the urlparse one. Added a PendingDeprecationWarning in the old
3499 module, it will be deprecated in the future.
3500
Marc-André Lemburgb339b2a2008-09-03 11:13:56 +00003501- Issue #2562: Fix distutils PKG-INFO writing logic to allow having

3507 path to the Python binary.
3508
Georg Brandl222e2082010-08-01 22:27:39 +00003509- Issue #3602: Moved test.test_support.catch_warning() to
Brett Cannon1eaf0742008-09-02 01:25:16 +00003510 warnings.catch_warnings() along with some API cleanup. Expanding the tests
3511 for catch_warnings() also led to an improvement in the raising of a
3512 DeprecationWarning related to warnings.warn_explicit().
3513
Benjamin Peterson973e6c22008-09-01 23:12:58 +00003514- The deprecation warnings for the old camelCase threading API were removed.
3515
Vinay Sajip35e3b032008-09-01 14:33:59 +00003516- logging: fixed lack of use of encoding attribute specified on a stream.
3517
Christian Heimesa27a62e2008-08-22 19:55:54 +00003518- Silenced a trivial compiler warning in the sqlite module.
3519
Christian Heimes1cc69632008-08-22 20:10:27 +00003520- Fixed two format strings in the _collections module.
3521
Benjamin Peterson17f03ca2008-09-01 14:18:30 +00003522- Issue #3703: _fileio.FileIO gave unhelpful error message when trying to open a
3523 directory.
Benjamin Petersonf22c26e2008-09-01 14:13:43 +00003524
Gregory P. Smithd7122032008-09-02 05:36:11 +00003525- Issue #3708: os.urandom no longer goes into an infinite loop when passed a
3526 non-integer floating point number.
3527
Vinay Sajip65d66e12008-09-04 07:31:21 +00003528- Issue #3110: multiprocessing fails to compiel on solaris 10 due to missing

3533
Jesse Noller438195f2009-01-18 21:04:36 +00003534- Issue #4301: Patch the logging module to add processName support, remove
3535 _check_logger_class from multiprocessing.
3536
Amaury Forgeot d'Arc293924b2008-09-02 23:19:56 +00003537- Issue #2975: When compiling several extension modules with Visual Studio 2008
3538 from the same python interpreter, some environment variables would grow
3539 without limit.
3540
Benjamin Peterson37346b22008-08-23 20:27:43 +00003541- Issue #3643: Added a few more checks to _testcapi to prevent segfaults by
3542 exploitation of poor argument checking.
3543
Gerhard Häringef2276b2008-09-12 13:54:06 +00003544- sqlite3: Changed docstring of iterdump() to mark method as "Non-standard".
3545
Gerhard Häring6e1afcf2008-09-12 18:58:57 +00003546- Issue #3103: Reduced globals symbols used by sqlite3 module and made sure all
3547 remaining ones have "pysqlite_" prefix.
3548
Gerhard Häringe6872eb2008-09-12 22:33:22 +00003549- Issue #3846: Release the GIL during sqlite3_prepare calls. This improves

3555
Nick Coghland2e09382008-09-11 12:11:06 +00003556- Issue #3781: Add test.test_support.check_warnings() as a convenience
3557 wrapper for warnings.catch_warnings() that makes it easier to check
3558 that expected warning messages are being reported.
3559
Amaury Forgeot d'Arcfeb8cad2008-09-06 20:53:51 +00003560- Issue #3796: Some tests functions were not enabled in test_float.
3561
3562- Issue #3768: Move test_py3kwarn over to the new API for catch_warnings().

Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00003578What's New in Python 2.6 beta 3?
3579================================
3580
Barry Warsaw07a4a382008-08-21 01:15:08 +00003581*Release date: 20-Aug-2008*
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00003582
3583Core and Builtins
3584-----------------
3585
Guido van Rossumf8402962008-08-20 15:01:50 +00003586- Issue #1878: Remove Py_TPFLAGS_HAVE_VERSION_TAG from
3587 Py_TPFLAGS_DEFAULT when not building the core. This means 3rd party
3588 extensions do not automatically benefit from the class attribute
3589 cache; they will have to explicitly add Py_TPFLAGS_HAVE_VERSION_TAG
3590 to their tp_flags field if they care. This is a backwards
3591 compatibility feature; in 3.0, all types will use the cache by
3592 default.
3593
Benjamin Petersonf647dc12008-08-20 01:27:30 +00003594- Keyword arguments can now follow starred arguments. (``f(a, *args,
3595 keyword=23)`` is now valid syntax.)
3596
Thomas Heller0ad5ae02008-08-19 19:25:04 +00003597- ctypes function pointers that are COM methods have a boolean True
3598 value again.
3599
Martin v. Löwisf91d46a2008-08-12 14:49:50 +00003600- Issue #3139: Make buffer-interface thread-safe wrt. PyArg_ParseTuple,
3601 by denying s# to parse objects that have a releasebuffer procedure,
3602 and introducing s*.
3603
Georg Brandl1e13ea92008-08-11 09:07:59 +00003604- Issue #3537: Fix an assertion failure when an empty but presized dict
3605 object was stored in the freelist.
3606
Mark Dickinsonb6467572008-08-04 21:30:09 +00003607- Issue #1481296: Make long(float('nan')) and int(float('nan')) raise
3608 ValueError consistently across platforms.
3609
Amaury Forgeot d'Arc39fd6722008-07-31 21:28:03 +00003610- Issue #3479: On platforms where sizeof(int) is smaller than sizeof(long)
3611 (64bit Unix, for example), unichr() would truncate its argument and return
3612 u'\x00' for unichr(2**32). Now it properly raises an OverflowError.
3613
Neal Norwitze7d8be82008-07-31 17:17:14 +00003614- Apply security patches from Apple.
3615
Amaury Forgeot d'Arc246daed2008-07-31 00:42:16 +00003616- Issue #2542: Now that issubclass() may call arbitrary code, ensure that
3617 PyErr_ExceptionMatches returns 0 when an exception occurs there.
3618
Antoine Pitrou92f82162008-07-25 22:22:08 +00003619- Issue #1819: function calls with several named parameters are now on
3620 average 35% faster (as measured by pybench).
3621
Amaury Forgeot d'Arce4921fe2008-07-21 22:00:38 +00003622- Issue #2378: An unexpected UnboundLocalError or NameError could appear when
3623 the python debugger steps into a class statement: the free variables (local
3624 variables defined in an outer scope) would be deleted from the outer scope.
3625
Gregory P. Smith0470bab2008-07-22 04:46:32 +00003626- Issue #2620: Overflow checking when allocating or reallocating memory
3627 was not always being done properly in some python types and extension
3628 modules. PyMem_MALLOC, PyMem_REALLOC, PyMem_NEW and PyMem_RESIZE have
3629 all been updated to perform better checks and places in the code that
3630 would previously leak memory on the error path when such an allocation
3631 failed have been fixed.
3632
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00003633Library
3634-------
3635
Hirokazu Yamamoto838c79f2008-08-20 13:14:07 +00003636- Issue #3612: Added some missing basic types in ctypes.wintypes.
3637
Benjamin Petersone977ad42008-08-20 01:42:01 +00003638- The methods ``is_in_tuple()``, ``is_vararg()``, and ``is_keywordarg()`` of
3639 symtable.Symbol have been deprecated for removal in 3.0 and the next release.
3640
Amaury Forgeot d'Arc351ffb82008-08-18 19:23:47 +00003641- Issue #2234: distutils failed for some versions of the cygwin compiler. The
3642 version reported by these tools does not necessarily follow the python
3643 version numbering scheme, so the module is less strict when parsing it.
3644
Nick Coghlanf70385a2008-08-18 12:42:46 +00003645- Issue #2235: Added Py3k warnings for types which will become unhashable
3646 under the stricter __hash__ inheritance rules in 3.0. Several types
3647 which did not meet the rules for hash invariants and were already
3648 unhashable in 3.0 have now been explicitly flagged as unhashable in
3649 2.6 as well (collections.Mapping, collections.Set, unittest.TestSuite,
3650 xml.dom.minidom.NamedNodeMap, numbers.Number, UserList.UserList)
3651
Brett Cannon88f801d2008-08-18 00:46:22 +00003652- Update __all__ for cookielib, csv, os, urllib2, and weakref to include things
3653 imported into the module but exposed as part of the module's API.
3654
Brett Cannon7b96f072008-08-18 00:41:11 +00003655- Remove an unneeded import of abc.ABCMeta from 'inspect'.

3660
Hirokazu Yamamoto41a81eb2008-08-17 13:10:46 +00003661- Issue #3575: Incremental decoder's decode function now takes bytearray
3662 by using 's*' instead of 't#'.
3663
Mark Dickinson3e4caeb2009-02-21 20:27:01 +00003664- Issue #2222: Fixed reference leak when occurred os.rename()
Hirokazu Yamamoto7f30a682008-08-17 09:46:56 +00003665 fails unicode conversion on 2nd parameter. (windows only)
3666
Georg Brandl222e2082010-08-01 22:27:39 +00003667- Issue #2464: urllib2 now supports a malformation in the URL received
Facundo Batista94f243a2008-08-17 03:38:39 +00003668 in a redirect.
3669
Brett Cannonabe423e2008-08-16 21:47:07 +00003670- Silence the DeprecationWarning raised when importing mimetools in
Brett Cannon721b1452008-08-16 22:00:27 +00003671 BaseHTTPServer, cgi (and rfc822), httplib.
Brett Cannonabe423e2008-08-16 21:47:07 +00003672
Facundo Batistaeb90b782008-08-16 14:44:07 +00003673- Issue #2776: fixed small issue when handling an URL with double slash
3674 after a 302 response in the case of not going through a proxy.
3675
Antoine Pitroub90a8be2008-08-15 21:03:21 +00003676- Issue #2676: in the email package, content-type parsing was hanging on
3677 pathological input because of quadratic or exponential behaviour of a
3678 regular expression.
3679
Antoine Pitrou11ec65d2008-08-14 21:04:30 +00003680- Issue #3476: binary buffered reading through the new "io" library is now
3681 thread-safe.
3682
Brett Cannonbf3157b2008-08-14 05:00:03 +00003683- Silence the DeprecationWarning of rfc822 when it is imported by mimetools
3684 since mimetools itself is deprecated. Because modules are cached, all
3685 subsequent imports of rfc822 will not raise a visible DeprecationWarning.
3686
Antoine Pitrou9fcd4b32008-08-11 17:21:36 +00003687- Issue #3134: shutil referenced undefined WindowsError symbol.
3688
Robert Schuppenies14646332008-08-10 11:01:53 +00003689- Issue #1342811: Fix leak in Tkinter.Menu.delete. Commands associated to
3690 menu entries were not deleted.

Antoine Pitroude781a42008-08-09 12:43:23 +00003721 asking for a specific length. This problem only affected files opened

3765
Nick Coghlan2a0c2b12008-08-04 12:47:17 +00003766- Issue #643841: The language reference now provides more detailed

3778-----------------
3779
Georg Brandl3e483f62008-07-16 22:57:41 +00003780- Issue #3156: Fix inconsistent behavior of the bytearray type: all
3781 its methods now allow for items objects that can be converted to
3782 an integer using operator.index().
3783
Mark Dickinson64b7e502008-07-16 09:40:03 +00003784- Issue #3360: Fix incorrect parsing of '020000000000.0', which
3785 produced a ValueError instead of giving the correct float.
3786
Eric Smitha5fa5a22008-07-16 00:11:49 +00003787- Issue #3083: Add alternate (#) formatting for bin, oct, hex output
3788 for str.format(). This adds the prefix 0b, 0o, or 0x, respectively.
3789
Mark Dickinson7103aa42008-07-15 19:08:33 +00003790- Issue #3008: the float type has a new instance method 'float.hex'
3791 and a new class method 'float.fromhex' to convert floating-point
3792 numbers to and from hexadecimal strings, respectively.
3793
Nick Coghlan6d6bd442008-07-15 15:40:22 +00003794- Issue #2235: __hash__ is once again inherited by default. To allow
3795 collections.Hashable to remain meaningful in the presence of the
3796 default hash implementation (object.__hash__), it is now possible
3797 to explicit block inheritance of hash by setting __hash__=None at
3798 the Python level, or tp_hash=PyObject_HashNotImplemented at the C
3799 level.
3800
Nick Coghlanb028f502008-07-13 14:52:36 +00003801- Issue #3221: Issue a RuntimeWarning instead of raising SystemError if
3802 the parent module cannot be found while performing an absolute import.
3803 This means that an incorrectly defined __package__ attribute will
3804 now only prevent relative imports in that module rather than causing
3805 all imports from that module to fail.
3806
Nick Coghlan14ff9942008-07-08 14:21:42 +00003807- Issue #2517: Allow unicode messages in Exceptions again by correctly

3817 another thread's dictionary.
3818
Mark Dickinson1ec2fcd2008-06-20 14:53:43 +00003819- Issue #3004: Minor change to slice.indices(): the start and stop
3820 arguments are now treated identically, making the behaviour easier
3821 to describe and understand. For example, slice(None, -10,
3822 1).indices(9) now returns (0, 0, 1) instead of (0, -1, 1), and
3823 slice(None, 10, -1).indices(10) returns (9, 9, -1) instead of (9,
3824 10, -1).
3825
Georg Brandl278fc502008-07-19 12:46:12 +00003826- Issue #3219: Calling a function with repeated keyword arguments,
3827 f(a=2, a=23), would not cause a syntax error. This was a regression
3828 from 2.4 caused by the switch to the new compiler.
Benjamin Peterson175e4d92008-07-01 19:34:52 +00003829
Georg Brandl278fc502008-07-19 12:46:12 +00003830- Issue #2862: Make int and float freelist management consistent with
3831 other freelists. Changes their CompactFreeList apis into

3838 api functions without holding the GIL, which could lead to a fatal
3839 error when they failed.
3840
Martin v. Löwisaabf4042008-08-02 07:20:25 +00003841- Issue #799428: Fix Tkinter.Misc._nametowidget to unwrap Tcl command objects.

Amaury Forgeot d'Arc0f7cddc2008-07-06 21:34:39 +00003866- Issue #839496: SimpleHTTPServer used to open text files in text mode. This is
3867 both unnecessary (HTTP allows text content to be sent in several forms) and
Andrew M. Kuchlingcc3f2b12008-07-10 14:43:31 +00003868 wrong because the actual transmitted size could differ from the
Amaury Forgeot d'Arc0f7cddc2008-07-06 21:34:39 +00003869 content-length. The problem had been corrected in the 2.4 branch, but never
3870 merged into trunk.

Nick Coghlanc060b0e2008-07-02 13:09:19 +00003885- Issue #3190: Pydoc now hides the automatic module attribute __package__ (the

4258 an extension. This was added for compatibility with Apple's build
4259 of Python.
4260
4261- The bundled OSX-specific copy of libbffi is now in sync with the version
4262 shipped with PyObjC 2.0 and includes support for x86_64 and ppc64 platforms.
4263
Georg Brandl25c34082008-08-18 23:09:49 +00004264- The threading module gained aliases for names that will be removed in the
4265 3.x series.

4273
Brett Cannonb61d8012008-05-11 23:39:04 +00004274- ``Lib/lib-old`` is now added to sys.path.
4275
Ronald Oussoren5640ce22008-06-05 12:58:24 +00004276- On MacOS X it is now possible to install the framework in 64-bit
4277 mode or even as a 4-way universal binary (that is, PPC, i386,
Georg Brandl5cc774e2008-06-11 20:28:06 +00004278 PPC64 and x86_64 support in one binary).
Ronald Oussoren5640ce22008-06-05 12:58:24 +00004279
4280 This is controlled by the configure argument ``--with-universal-archs``:
4281
4282 - ``--with-universal-archs=all``: install 4-way universal
4283
4284 - ``--with-universal-archs=32-bit``: install 2-way universal, 32-bit (the default)
4285
4286 - ``--with-universal-archs=64-bit``: install 2-way universal, 64-bit
4287
4288 This option should be used in combination with ``--enable-universalsdk=``.
4289
4290 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 +00004299
4300- The PyString functions have been renamed to PyBytes. A batch of
4301 defines were added so that the linker still sees the original
4302 PyString names.

Georg Brandl3ee81df2008-05-17 18:14:43 +00004340- Issue #1631171: Re-implement the 'warnings' module in C (the
4341 original Python code has been kept as backup). This will allow for
4342 using the 'warning's machinery in such places as the parser where
4343 use of pure Python code is not possible. Both the ``showarning()``
4344 and ``formatwarning()`` gain an optional 'line' argument which is
4345 not called by default for backwards-compatibility reasons. Setting
4346 ``warnings.showwarning()`` to an implementation that lacks support
4347 for the ``line`` argument will raise a DeprecationWarning.

Gregory P. Smithd59fefb2008-04-22 08:11:33 +00004372- The getpass module has been improved on Unix. It now uses /dev/tty
4373 by default and uses stderr instead of stdout. A GetPassWarning is
4374 issued when input echo cannot be controlled.

Georg Brandl3ee81df2008-05-17 18:14:43 +00004389- Issue #2513: distutils on Windows is now capable of cross-compiling
Mark Hammond495cf992008-04-07 01:53:39 +00004390 extension modules between 32 and 64 bit platforms. See the distutls

Georg Brandl3ee81df2008-05-17 18:14:43 +00004410- Issue #2550: The approach used by client/server code for obtaining
4411 ports to listen on in network-oriented tests has been refined in an
4412 effort to facilitate running multiple instances of the entire
4413 regression test suite in parallel without issue.
4414 test_support.bind_port() has been fixed such that it will always
4415 return a unique port -- which wasn't always the case with the
4416 previous implementation, especially if socket options had been set
4417 that affected address reuse (i.e. SO_REUSEADDR, SO_REUSEPORT). The
4418 new implementation of bind_port() will actually raise an exception
4419 if it is passed an AF_INET/SOCK_STREAM socket with either the
4420 SO_REUSEADDR or SO_REUSEPORT socket option set. Furthermore, if
4421 available, bind_port() will set the SO_EXCLUSIVEADDRUSE option on
4422 the socket it's been passed. This currently only applies to
4423 Windows. This option prevents any other sockets from binding to the
4424 host/port we've bound to, thus removing the possibility of the
4425 'non-deterministic' behaviour, as Microsoft puts it, that occurs
4426 when a second SOCK_STREAM socket binds and accepts to a host/port
4427 that's already been bound by another socket. The optional preferred
4428 port parameter to bind_port() has been removed. Under no
4429 circumstances should tests be hard coding ports!
4430
4431 test_support.find_unused_port() has also been introduced, which will
4432 pass a temporary socket object to bind_port() in order to obtain an
4433 unused port. The temporary socket object is then closed and
4434 deleted, and the port is returned. This method should only be used
4435 for obtaining an unused port in order to pass to an external program
4436 (i.e. the -accept [port] argument to openssl's s_server mode) or as
4437 a parameter to a server-oriented class that doesn't give you direct
4438 access to the underlying socket used.
4439
4440 Finally, test_support.HOST has been introduced, which should be used
4441 for the host argument of any relevant socket calls (i.e. bind and
4442 connect).
Trent Nelsone41b0062008-04-08 23:47:30 +00004443
4444 The following tests were updated to following the new conventions:
Georg Brandl3ee81df2008-05-17 18:14:43 +00004445 test_socket, test_smtplib, test_asyncore, test_ssl, test_httplib,
Trent Nelsone41b0062008-04-08 23:47:30 +00004446 test_poplib, test_ftplib, test_telnetlib, test_socketserver,
4447 test_asynchat and test_socket_ssl.
4448
Georg Brandl3ee81df2008-05-17 18:14:43 +00004449 It is now possible for multiple instances of the regression test
4450 suite to run in parallel without issue.

Eric Smitha73fbe72008-02-23 03:09:44 +00004729- Added the future_builtins module, which contains hex() and oct().
4730 These are the PEP 3127 version of these functions, designed to be
4731 compatible with the hex() and oct() builtins from Python 3.0. They
4732 differ slightly in their output formats from the existing, unchanged
4733 Python 2.6 builtins. The expected usage of the future_builtins
4734 module is:
4735 from future_builtins import hex, oct
4736
Eric Smith7ef40bf2008-02-20 23:34:22 +00004737- Issue #1600: Modifed PyOS_ascii_formatd to use at most 2 digit
4738 exponents for exponents with absolute value < 100. Follows C99
4739 standard. This is a change on Windows, which would use 3 digits.
4740 Also, added 'n' to the formats that PyOS_ascii_formatd understands,
4741 so that any alterations it does to the resulting string will be
4742 available in stringlib/formatter.h (for float.__format__).
4743
Eric Smith5a3c1352008-02-19 13:21:56 +00004744- Implemented PEP 3101, Advanced String Formatting. This adds a new
4745 builtin format(); a format() method for str and unicode; a
4746 __format__() method to object, str, unicode, int, long, float, and
4747 datetime; the class string.Formatter; and the C API
4748 PyObject_Format().
4749
Georg Brandl3ee81df2008-05-17 18:14:43 +00004750- Fixed several potential crashes, all caused by specially crafted
4751 __del__ methods exploiting objects in temporarily inconsistent
4752 state.

Vinay Sajipb7edfc42008-04-02 21:10:23 +00004754- Issue #2115: Important speedup in setting __slot__ attributes. Also
Georg Brandl3ee81df2008-05-17 18:14:43 +00004755 prevent a possible crash: an Abstract Base Class would try to access
4756 a slot on a registered virtual subclass.

4763 memory to the OS earlier.
Christian Heimes3b718a72008-02-14 12:47:33 +00004764
Georg Brandl3ee81df2008-05-17 18:14:43 +00004765- Issue #2045: Fix an infinite recursion triggered when printing a
4766 subclass of collections.defaultdict, if its default_factory is set
4767 to a bound method.
Amaury Forgeot d'Arcb01aa432008-02-08 00:56:02 +00004768
Christian Heimesf75dbef2008-02-08 00:11:31 +00004769- Fixed a minor memory leak in dictobject.c. The content of the free
4770 list was not freed on interpreter shutdown.
4771
Georg Brandl21e99f42010-03-07 15:23:59 +00004772- Limit free list of method and built-in function objects to 256

4776 functions ``PyInt_CompactFreeList`` and ``PyFloat_CompactFreeList``
Christian Heimes422051a2008-02-04 18:00:12 +00004777 to compact the internal free lists of pre-allocted ints and floats.
4778
Georg Brandl3ee81df2008-05-17 18:14:43 +00004779- Issue #1983: Fixed return type of fork(), fork1() and forkpty()
4780 calls. Python expected the return type int but the fork familie
4781 returns pi_t.
Christian Heimes951cc0f2008-01-31 23:08:23 +00004782
Georg Brandl3ee81df2008-05-17 18:14:43 +00004783- Issue #1678380: Fix a bug that identifies 0j and -0j when they
4784 appear in the same code unit.
Mark Dickinson105be772008-01-31 22:17:37 +00004785
Georg Brandl3ee81df2008-05-17 18:14:43 +00004786- Issue #2025: Add tuple.count() and tuple.index() methods to comply
4787 with the collections.Sequence API.
Raymond Hettinger5b07ebc2008-02-07 00:54:20 +00004788
Georg Brandl3ee81df2008-05-17 18:14:43 +00004789- Patch #1970 by Antoine Pitrou: Speedup unicode whitespace and
4790 linebreak detection

Georg Brandl3ee81df2008-05-17 18:14:43 +00004792- Added ``PyType_ClearCache()`` and ``sys._clear_type_cache`` to clear
4793 the internal lookup cache for ref leak tests.
Christian Heimes908caac2008-01-27 23:34:59 +00004794
Georg Brandl3ee81df2008-05-17 18:14:43 +00004795- Patch #1473257: generator objects gain a gi_code attribute. This is
4796 the same object as the func_code attribute of the function that
4797 produced the generator.
Georg Brandl0cdf9a32008-01-26 14:14:20 +00004798
Georg Brandl3ee81df2008-05-17 18:14:43 +00004799- Issue #1920: "while 0" statements were completely removed by the
4800 compiler, even in the presence of an "else" clause, which is
4801 supposed to be run when the condition is false. Now the compiler
4802 correctly emits bytecode for the "else" suite.
Amaury Forgeot d'Arc31eaafe2008-01-24 22:59:25 +00004803
Guido van Rossumeead05f2008-01-24 18:21:02 +00004804- A few crashers fixed: weakref_in_del.py (issue #1377858);
4805 loosing_dict_ref.py (issue #1303614, test67.py);
4806 borrowed_ref_[34].py (not in tracker).
4807
Vinay Sajipd7cf32e2008-01-24 12:43:33 +00004808- Issue #1069410: The "can't load dll" message box on Windows is
Christian Heimesb2302ba2008-01-23 17:15:06 +00004809 suppressed while an extension is loaded by calling SetErrorMode in
4810 dynload_win.c. The error is still reported properly.
4811
Georg Brandl3ee81df2008-05-17 18:14:43 +00004812- Issue #1915: Python compiles with --enable-unicode=no again. However
Christian Heimes082c9b02008-01-23 14:20:50 +00004813 several extension methods and modules do not work without unicode
4814 support.
4815
Georg Brandl26543b12008-01-21 18:36:51 +00004816- Issue #1882: when compiling code from a string, encoding cookies in the
4817 second line of code were not always recognized correctly.
4818
Georg Brandl14404b62008-01-19 19:27:05 +00004819- Issue #1679: "0x" was taken as a valid integer literal.
4820
Georg Brandl6caad7d2008-01-26 14:19:22 +00004821- Issue #1865: ``bytes`` as an alias for ``str`` and b"" as an alias "" were
Christian Heimes288e89a2008-01-18 18:24:07 +00004822 added.
4823
Christian Heimesc94e2b52008-01-14 04:13:37 +00004824- sys.float_info / PyFloat_GetInfo: The floating point information
4825 object was converted from a dict to a specialized structseq object.
4826
Georg Brandl3ee81df2008-05-17 18:14:43 +00004827- Patch #1816: Added sys.flags structseq. It exposes the status of
4828 most command line arguments and PYTHON* environment variables.
Christian Heimesf31b69f2008-01-14 03:42:48 +00004829
Georg Brandl3ee81df2008-05-17 18:14:43 +00004830- Objects/structseq.c: Implemented new structseq representation. The
4831 patch makes structseqs (e.g. the return value of os.stat) more
4832 readable.
Christian Heimes9c201962008-01-14 03:33:52 +00004833
Georg Brandl3ee81df2008-05-17 18:14:43 +00004834- Patch #1700288: added a type attribute cache that caches method
4835 accesses, resulting in speedups in heavily object-oriented code.
Amaury Forgeot d'Arce4c270c2008-01-14 00:29:41 +00004836
Neal Norwitz3fc15b82008-01-10 05:42:58 +00004837- Bug #1776: __import__() no longer accepts filenames on any platform.
4838 The first parameter to __import__() must be a valid module name.
Christian Heimes3403f152008-01-09 19:56:33 +00004839
Georg Brandlaed6c662008-01-07 17:25:53 +00004840- Patch #1668: renamed THREADDEBUG envvar to PYTHONTHREADDEBUG.
4841
Georg Brandl3ee81df2008-05-17 18:14:43 +00004842- Patch #602345: Add -B command line option, PYTHONDONTWRITEBYTECODE
4843 envvar and sys.dont_write_bytecode attribute. All these can be set
4844 to forbid Python to attempt to write compiled bytecode files.
Georg Brandl2da0fce2008-01-07 17:09:35 +00004845
Georg Brandl3ee81df2008-05-17 18:14:43 +00004846- Improve some exception messages when Windows fails to load an
4847 extension module. Now we get for example '%1 is not a valid Win32
4848 application' instead of 'error code 193'.
Amaury Forgeot d'Arce0b76952008-01-04 02:04:15 +00004849

Christian Heimes0a8143f2007-12-18 23:22:54 +00004855- Issue #1635: Platform independent creation and representation of NaN
Georg Brandl3ee81df2008-05-17 18:14:43 +00004856 and INF. float("nan"), float("inf") and float("-inf") now work on
4857 every platform with IEEE 754 semantics.
Christian Heimes0a8143f2007-12-18 23:22:54 +00004858
Georg Brandl3ee81df2008-05-17 18:14:43 +00004859- Compiler now generates simpler and faster code for dictionary
4860 literals. The oparg for BUILD_MAP now indicates an estimated
4861 dictionary size. There is a new opcode, STORE_MAP, for adding
4862 entries to the dictionary.

Georg Brandl3ee81df2008-05-17 18:14:43 +00004891- Patch #1739468: Directories and zipfiles containing a __main__.py
4892 file can now be directly executed by passing their name to the
4893 interpreter. The directory/zipfile is automatically inserted as the
4894 first entry in sys.path.
Nick Coghlan327a39b2007-11-18 11:56:28 +00004895
Georg Brandl3ee81df2008-05-17 18:14:43 +00004896- Issue #1265: Fix a problem with sys.settrace, if the tracing
4897 function uses a generator expression when at the same time the
4898 executed code is closing a paused generator.
Amaury Forgeot d'Arc0d75f092007-11-13 21:54:28 +00004899
Raymond Hettinger1760c8a2007-11-08 02:52:43 +00004900- sets and frozensets now have an isdisjoint() method.
4901
Raymond Hettinger3f8caa32007-10-24 01:28:33 +00004902- optimize the performance of builtin.sum().
4903
Neal Norwitz44f326e2007-10-05 05:29:17 +00004904- Fix warnings found by the new version of the Coverity checker.
4905
Georg Brandl21e99f42010-03-07 15:23:59 +00004906- The enumerate() built-in function is no longer bounded to sequences
Georg Brandl3ee81df2008-05-17 18:14:43 +00004907 smaller than LONG_MAX. Formerly, it raised an OverflowError. Now,
4908 automatically shifts from ints to longs.
Raymond Hettinger8f669372007-10-03 21:18:11 +00004909
Georg Brandl3ee81df2008-05-17 18:14:43 +00004910- Issue #1686386: Tuple's tp_repr did not take into account the
4911 possibility of having a self-referential tuple, which is possible
4912 from C code. Nor did object's tp_str consider that a type's tp_str
4913 could do something that could lead to an inifinite recursion.
4914 Py_ReprEnter() and Py_EnterRecursiveCall(), respectively, fixed the
4915 issues.
Brett Cannon0b14f242007-09-30 19:45:10 +00004916
Georg Brandl3ee81df2008-05-17 18:14:43 +00004917- Issue #1164: It was possible to trigger deadlock when using the
4918 'print' statement to write to a file since the GIL was not released
4919 as needed. Now PyObject_Print() does the right thing along with
4920 various tp_print implementations of the built-in types and those in
4921 the collections module.
Brett Cannon01531592007-09-17 03:28:34 +00004922
Georg Brandl3ee81df2008-05-17 18:14:43 +00004923- Issue #1147: Exceptions were directly allowing string exceptions in
4924 their throw() method even though string exceptions no longer
4925 allowed.
Brett Cannon4c20bc42007-09-11 21:02:28 +00004926
Georg Brandl3ee81df2008-05-17 18:14:43 +00004927- Issue #1096: Prevent a segfault from getting the repr of a very
4928 deeply nested list by using the recursion counter.
Brett Cannona0c05512007-09-10 21:38:27 +00004929
Brett Cannon1e534b52007-09-07 04:18:30 +00004930- Issue #1202533: Fix infinite recursion calls triggered by calls to
Georg Brandl3ee81df2008-05-17 18:14:43 +00004931 PyObject_Call() never calling back out to Python code to trigger
4932 recursion depth updates/checks. Required the creation of a static
4933 RuntimeError instance in case normalizing an exception put the
4934 recursion check value past its limit. Fixes crashers
4935 infinite_rec_(1|2|4|5).py.
Brett Cannon1e534b52007-09-07 04:18:30 +00004936

Neal Norwitz0ac60192007-05-27 04:08:54 +00004950- Add new attribute names for function objects. All the func_* become
Georg Brandl3ee81df2008-05-17 18:14:43 +00004951 __*__ attributes. (Some already existed, e.g., __doc__ and
4952 __name__.)
Neal Norwitz0ac60192007-05-27 04:08:54 +00004953
Neal Norwitz8b2bfbc2007-05-23 06:35:32 +00004954- Add -3 option to the interpreter to warn about features that are
4955 deprecated and will be changed/removed in Python 3.0.
4956
Georg Brandl2134e752007-05-21 20:34:16 +00004957- Patch #1686487: you can now pass any mapping after '**' in function
4958 calls.
4959
Collin Winter62903052007-05-18 23:11:24 +00004960- except clauses may now be spelled either "except E, target:" or
Georg Brandl3ee81df2008-05-17 18:14:43 +00004961 "except E as target:". This is to provide forwards compatibility
4962 with Python 3.0.

Brett Cannon229cee22007-05-05 01:34:02 +00004964- Deprecate BaseException.message as per PEP 352.
4965
Georg Brandl3ee81df2008-05-17 18:14:43 +00004966- Issue #1303614: don't expose object's __dict__ when the dict is
Georg Brandl21e99f42010-03-07 15:23:59 +00004967 inherited from a built-in base.

Vinay Sajip8549ce32007-05-06 17:53:37 +00004969- When __slots__ are set to a unicode string, make it work the same as
Neal Norwitzcbd9ee62007-04-14 05:25:50 +00004970 setting a plain string, ie don't expand to single letter identifiers.
4971
Raymond Hettinger13936692007-04-11 18:40:58 +00004972- Request #1191699: Slices can now be pickled.
4973
Raymond Hettinger4db5fe92007-04-12 04:10:00 +00004974- Request #1193128: str.translate() now allows a None argument for
4975 translations that only remove characters without re-mapping the
4976 remaining characters.
4977
Georg Brandl5cb76c12007-03-21 09:00:39 +00004978- Patch #1682205: a TypeError while unpacking an iterable is no longer
4979 masked by a generic one with the message "unpack non-sequence".
4980
Neal Norwitzaa754b72007-03-21 06:39:48 +00004981- Remove unused file Python/fmod.c.
4982
Guido van Rossum143b5642007-03-23 04:58:42 +00004983- Bug #1683368: The object.__init__() and object.__new__() methods are
4984 now stricter in rejecting excess arguments. The only time when
4985 either allows excess arguments is when it is not overridden and the
4986 other one is. For backwards compatibility, when both are
4987 overridden, it is a deprecation warning (for now; maybe a Py3k
Guido van Rossum234b1ff2007-03-23 19:39:01 +00004988 warning later). Also, type.__init__() insists on the same signature
4989 as supported by type.__new__().

Georg Brandl3ee81df2008-05-17 18:14:43 +00004991- Patch #1675423: PyComplex_AsCComplex() now tries to convert an
4992 object to complex using its __complex__() method before falling back
4993 to the __float__() method. Therefore, the functions in the cmath
4994 module now can operate on objects that define a __complex__()
4995 method.

Georg Brandl871f1bc2007-03-12 13:17:36 +00005016- The dir() function has been extended to call the __dir__() method on
Georg Brandl3ee81df2008-05-17 18:14:43 +00005017 its argument, if it exists. If not, it will work like before. This
5018 allows customizing the output of dir() in the presence of a
5019 __getattr__().

Georg Brandl3ee81df2008-05-17 18:14:43 +00005543 the client's request was successfully received, understood, and

Georg Brandl3ee81df2008-05-17 18:14:43 +00005584 AttributeError instead of an IOError when the server's response

Georg Brandl92a6bae2007-03-13 17:43:32 +00005618- Patch #1603688: ConfigParser.SafeConfigParser now checks values that
Georg Brandl3ee81df2008-05-17 18:14:43 +00005619 are set for invalid interpolation sequences that would lead to

5676 TestCase and TestSuite subclasses (not instances) are no longer

Georg Brandl3ee81df2008-05-17 18:14:43 +00006069 time so that opening a database previously created with the DB_DUP
6070 or DB_DUPSORT flag set will keep the proper behavior on subsequent
6071 opens. Specifically: dictionary assignment to a DB object will
6072 replace all values for a given key when the database allows
6073 duplicate values. DB users should use DB.put(k, v) when they want
6074 to store duplicates; not DB[k] = v.

6081 characters with ASCII value less than 32. Also, it correctly quotes
6082 dots only if they occur on a single line, as opposed to the previous
6083 behavior of quoting dots if they are the second character of any
6084 line.
