Ezio Melottiab2eb0e2010-06-05 19:21:32 +0000399- Issue #8271: during the decoding of an invalid UTF-8 byte sequence, only the
400 start byte and the continuation byte(s) are now considered invalid, instead
401 of the number of bytes specified by the start byte.
402 E.g.: '\xf1\x80AB'.decode('utf-8', 'replace') now returns u'\ufffdAB' and
403 replaces with U+FFFD only the start byte ('\xf1') and the continuation byte
404 ('\x80') even if '\xf1' is the start byte of a 4-bytes sequence.

415 (2**53+1 == complex(2**53) == 2**53), breaking transivity of equality.

Georg Brandlfee0f442010-05-22 21:26:21 +0000611- Issue #8567: Fix precedence of signals in Decimal module: when a Decimal
612 operation raises multiple signals and more than one of those signals is

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

Georg Brandlfee0f442010-05-22 21:26:21 +0000855- Issue #7279: Comparisons involving a Decimal signaling NaN now signal
856 InvalidOperation instead of returning False. (Comparisons involving a quiet
857 NaN are unchanged.) Also, Decimal quiet NaNs are now hashable; Decimal
858 signaling NaNs remain unhashable.

Georg Brandlfee0f442010-05-22 21:26:21 +0000860- Issue #2531: Comparison operations between floats and Decimal instances now
861 return a result based on the numeric values of the operands; previously they
862 returned an arbitrary result based on the relative ordering of id(float) and
863 id(Decimal).

Barry Warsawf7f2d6f2010-03-31 21:07:16 +0000865- Issue #8233: When run as a script, py_compile.py optionally takes a single
Georg Brandlfee0f442010-05-22 21:26:21 +0000866 argument `-` which tells it to read files to compile from stdin. Each line is
867 read on demand and the named file is compiled immediately. (Original patch by
868 Piotr Ożarowski).

Georg Brandlfee0f442010-05-22 21:26:21 +0000877- Comparisons using one of <, <=, >, >= between a complex instance and a
878 Fractions instance now raise TypeError instead of returning True/False. This
879 makes Fraction <=> complex comparisons consistent with int <=> complex, float
880 <=> complex, and complex <=> complex comparisons.

Georg Brandlba83f822010-03-14 09:50:54 +0000984- Issue #1530559: When passing a non-integer argument to struct.pack with *any*
985 integer format code (one of 'bBhHiIlLqQ'), struct.pack attempts to use the

Georg Brandlfee0f442010-05-22 21:26:21 +0000987 produces a DeprecationWarning in this case. (In Python 2.6, the behaviour was
988 inconsistent: __int__ was used for some integer codes but not for others, and
989 the set of integer codes for which it was used differed between native packing
990 and standard packing.)

Georg Brandlba83f822010-03-14 09:50:54 +00001287 specified, rather than fall through to AF_PACKET (in the ``socket`` module).

Georg Brandlba83f822010-03-14 09:50:54 +00001294 file position when calling `truncate()`. It would previously change the file
1295 position to the given argument, which goes against the tradition of
Antoine Pitrouf3fa0742010-01-31 22:26:04 +00001296 ftruncate() and other truncation APIs. Patch by Pascal Chambon.

1299 class used to represent files stored inside an archive. The new
1300 implementation is significantly faster and can be wrapped in a

1398
Mark Dickinson1b34d252010-01-01 17:27:30 +00001399- Issue #5080: A number of functions and methods previously produced a
Georg Brandlba83f822010-03-14 09:50:54 +00001400 DeprecationWarning when passed a float argument where an integer was expected.
1401 These functions and methods now raise TypeError instead. The majority of the
1402 effects of this change are in the extension modules, but some core functions
1403 and methods are affected: notably the 'chr', 'range' and 'xrange' builtins,
1404 and many unicode/str methods.

1419 least on IEEE 754 platforms), and in particular does not depend on the
1420 internal representation of a long.

Georg Brandlba83f822010-03-14 09:50:54 +00001566- Issue #7419: ``locale.setlocale()`` could crash the interpreter on Windows
1567 when called with invalid values.
Amaury Forgeot d'Arcd7288712009-12-01 21:51:04 +00001568
Georg Brandlba83f822010-03-14 09:50:54 +00001569- Issue #3382: 'F' formatting for float and complex now convert the result to
1570 upper case. This only affects 'inf' and 'nan', since 'f' no longer converts
1571 to 'g' for large values.
Amaury Forgeot d'Arcd7288712009-12-01 21:51:04 +00001572
Georg Brandlba83f822010-03-14 09:50:54 +00001573- Remove switch from "%f" formatting to "%g" formatting for floats larger than
1574 1e50 in absolute value.
Mark Dickinson9dd5e162009-11-23 20:54:09 +00001575
Georg Brandlba83f822010-03-14 09:50:54 +00001576- Remove restrictions on precision when formatting floats. E.g., "%.120g" %
1577 1e-100 used to raise OverflowError, but now gives the requested 120
1578 significant digits instead.
Mark Dickinson18cfada2009-11-23 18:46:41 +00001579
Georg Brandlba83f822010-03-14 09:50:54 +00001580- Add Py3k warnings for parameter names in parentheses.
Benjamin Peterson89b1a5c2009-11-19 22:58:01 +00001581
Georg Brandlba83f822010-03-14 09:50:54 +00001582- Issue #7362: Give a proper error message for ``def f((x)=3): pass``.
Benjamin Peterson89b1a5c2009-11-19 22:58:01 +00001583
Georg Brandlba83f822010-03-14 09:50:54 +00001584- Issue #7085: Fix crash when importing some extensions in a thread on MacOSX
1585 10.6.
Ronald Oussoren315cd0c2009-11-19 16:25:21 +00001586
Georg Brandlba83f822010-03-14 09:50:54 +00001587- Issue #7117: ``repr(x)`` for a float x returns a result based on the shortest
1588 decimal string that's guaranteed to round back to x under correct rounding
1589 (with round-half-to-even rounding mode). Previously it gave a string based on
1590 rounding x to 17 decimal digits. repr(x) for a complex number behaves
1591 similarly. On platforms where the correctly-rounded strtod and dtoa code is
1592 not supported (see below), repr is unchanged.
Mark Dickinsonb678de82009-11-19 18:41:49 +00001593
Georg Brandlba83f822010-03-14 09:50:54 +00001594- Issue #7117: On almost all platforms: float-to-string and string-to-float
1595 conversions within Python are now correctly rounded. Places these conversions
1596 occur include: str for floats and complex numbers; the float and complex
1597 constructors; old-style and new-style numeric formatting; serialization and
1598 deserialization of floats and complex numbers using marshal, pickle and json;
1599 parsing of float and imaginary literals in Python code; Decimal-to-float
1600 conversion.
Mark Dickinsonb678de82009-11-19 18:41:49 +00001601
Georg Brandlba83f822010-03-14 09:50:54 +00001602 The conversions use a Python-adapted version of David Gay's well-known dtoa.c,
1603 providing correctly-rounded strtod and dtoa C functions. This code is
1604 supported on Windows, and on Unix-like platforms using gcc, icc or suncc as
1605 the C compiler. There may be a small number of platforms on which correct
1606 operation of this code cannot be guaranteed, so the code is not used: notably,
1607 this applies to platforms where the C double format is not IEEE 754 binary64,
1608 and to platforms on x86 hardware where the x87 FPU is set to 64-bit precision
1609 and Python's configure script is unable to determine how to change the FPU
1610 precision. On these platforms conversions use the platform strtod and dtoa,
1611 as before.
Mark Dickinsonb678de82009-11-19 18:41:49 +00001612
Georg Brandlba83f822010-03-14 09:50:54 +00001613- Issue #7117: Backport round implementation from Python 3.x. ``round()`` now
1614 uses the correctly-rounded string <-> float conversions described above (when
1615 available), and so produces correctly rounded results that will display nicely
1616 under the float repr. There are two related small changes: (1) round now
1617 accepts any class with an ``__index__()`` method for its second argument (but
1618 no longer accepts floats for the second argument), and (2) an excessively
1619 large second integer argument (e.g., ``round(1.234, 10**100)``) no longer
1620 raises an exception.
Mark Dickinsonbd15a062009-11-18 19:33:35 +00001621
Philip Jenveyfab8be22009-11-17 02:42:26 +00001622- Issue #1757126: Fix the cyrillic-asian alias for the ptcp154 encoding.
1623
Georg Brandlba83f822010-03-14 09:50:54 +00001624- Fix several issues with ``compile()``. The input can now contain Windows and
1625 Mac newlines and is no longer required to end in a newline.
Benjamin Petersone36199b2009-11-12 23:39:44 +00001626
Georg Brandlba83f822010-03-14 09:50:54 +00001627- Remove length limitation when constructing a complex number from a unicode
1628 string.
Mark Dickinsonc04c7c52009-10-26 22:28:14 +00001629
Georg Brandlba83f822010-03-14 09:50:54 +00001630- Issue #7244: ``itertools.izip_longest()`` no longer ignores exceptions raised
1631 during the formation of an output tuple.
Raymond Hettingerfa7dadd2009-11-01 20:45:16 +00001632

1634
Georg Brandlba83f822010-03-14 09:50:54 +00001635- Issue #1722344: ``threading._shutdown()`` is now called in ``Py_Finalize()``,
1636 which fixes the problem of some exceptions being thrown at shutdown when the
1637 interpreter is killed. Patch by Adam Olsen.
Antoine Pitrouefb60c02009-10-20 21:29:37 +00001638

1640 and note that they are unsafe and deprecated.
Eric Smithc12781a2009-10-19 14:38:14 +00001641

1646 module is the only object holding a reference to it.
Benjamin Peterson196b0922009-10-15 15:44:46 +00001647
Georg Brandlba83f822010-03-14 09:50:54 +00001648- Issue #1754094: Improve the stack depth calculation in the compiler. There
1649 should be no other effect than a small decrease in memory use. Patch by
1650 Christopher Tur Lesniewski-Laas.
Neil Schemenauer7fdd1cb2009-10-14 17:17:14 +00001651
Georg Brandlba83f822010-03-14 09:50:54 +00001652- Issue #7084: Fix a (very unlikely) crash when printing a list from one thread,
1653 and mutating it from another one. Patch by Scott Dial.
Antoine Pitroubeaf6a02009-10-11 21:03:26 +00001654
Amaury Forgeot d'Arcd0052d12009-10-06 19:56:32 +00001655- Issue #1571184: The Unicode database contains properties for more characters.
1656 The tables for code points representing numeric values, white spaces or line
1657 breaks are now generated from the official Unicode Character Database files,
1658 and include information from the Unihan.txt file.
1659

1664 running through the shell. Patch by Jean-Paul Calderone and Jani Hakala.
Philip Jenvey8b902042009-09-29 19:10:15 +00001665
Georg Brandlba83f822010-03-14 09:50:54 +00001666- Issue #7019: Raise ValueError when unmarshalling bad long data, instead of

Mark Dickinsonb1d45852009-05-11 15:33:08 +00001762
Georg Brandlba83f822010-03-14 09:50:54 +00001763 (1) inf and nan strings with trailing whitespace were incorrectly rejected;
1764 (2) parsing of strings representing infinities and nans was locale aware; and

Georg Brandlba83f822010-03-14 09:50:54 +00001767- Issue #5920: For ``float.__format__()``, change the behavior with the empty
1768 presentation type (that is, not one of 'e', 'f', 'g', or 'n') to be like 'g'
1769 but with at least one decimal point and with a default precision
1770 of 12. Previously, the behavior the same but with a default precision of 6.
1771 This more closely matches ``str()``, and reduces surprises when adding
1772 alignment flags to the empty presentation type. This also affects the new
1773 complex.__format__ in the same way.
1774
1775- Issue #5890: In subclasses of 'property' the __doc__ attribute was shadowed by

Walter Dörwalded960ac2009-05-03 22:36:33 +00002025- Issue #5108: Handle %s like %S and %R in PyUnicode_FromFormatV(): Call
2026 PyUnicode_DecodeUTF8() once, remember the result and output it in a second

2035 gives improved memory leak detection when running under Valgrind, while taking
2036 advantage of pymalloc at other times.

Amaury Forgeot d'Arc05e34492008-09-10 22:04:45 +00003403- Issue #3743: In a few places, PY_FORMAT_SIZE_T was incorrectly used with
3404 PyString_FromFormat or PyErr_Format to display size_t values. The macro
3405 PY_FORMAT_SIZE_T is designed to select the correct format for the OS
3406 ``printf`` function, whereas PyString_FromFormat has an independent
3407 implementation and uses "%zd" on all platforms for size_t values.
3408 This makes a difference on win64, where ``printf`` needs "%Id" to display

Benjamin Peterson97179b02008-09-09 20:55:01 +00003411- Issue #3634: _weakref.ref(Exception).__init__() gave invalid return value on
3412 error.
3413
Amaury Forgeot d'Arcd3ffb892008-09-09 07:24:30 +00003414- Issue #3777: long() applied to a float object now always return a long
3415 object; previously an int would be returned for small values. the __long__
3416 method is allowed to return either an int or a long, but the behaviour of
3417 float objects should not change to respect backward compatibility.
3418
Amaury Forgeot d'Arc3571fbf2008-09-01 19:52:00 +00003419- Issue #3751: str.rpartition would perform a left-partition when called with
3420 a unicode argument.

Antoine Pitroud4ae97b2008-08-29 18:39:48 +00003424- Issue #3668: Fix a memory leak with the "s*" argument parser in
Vinay Sajip35e3b032008-09-01 14:33:59 +00003425 PyArg_ParseTuple and friends, which occurred when the argument for "s*"
Antoine Pitroud4ae97b2008-08-29 18:39:48 +00003426 was correctly parsed but parsing of subsequent arguments failed.
3427
Vinay Sajip35e3b032008-09-01 14:33:59 +00003428- Issue #2534: speed up isinstance() and issubclass() by 50-70%, so as to
Antoine Pitrou0668c622008-08-26 22:42:08 +00003429 match Python 2.5 speed despite the __instancecheck__ / __subclasscheck__
3430 mechanism. In the process, fix a bug where isinstance() and issubclass(),
3431 when given a tuple of classes as second argument, were looking up
3432 __instancecheck__ / __subclasscheck__ on the tuple rather than on each
3433 type object.
3434
Neal Norwitz18aa3882008-08-24 05:04:52 +00003435- Fix crashes on memory allocation failure found with failmalloc.

Brett Cannon1eaf0742008-09-02 01:25:16 +00003504 warnings.catch_warnings() along with some API cleanup. Expanding the tests
3505 for catch_warnings() also led to an improvement in the raising of a
3506 DeprecationWarning related to warnings.warn_explicit().

3534
Benjamin Peterson37346b22008-08-23 20:27:43 +00003535- Issue #3643: Added a few more checks to _testcapi to prevent segfaults by

Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00003572What's New in Python 2.6 beta 3?
3573================================
3574
Barry Warsaw07a4a382008-08-21 01:15:08 +00003575*Release date: 20-Aug-2008*
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00003576
3577Core and Builtins
3578-----------------
3579
Guido van Rossumf8402962008-08-20 15:01:50 +00003580- Issue #1878: Remove Py_TPFLAGS_HAVE_VERSION_TAG from
3581 Py_TPFLAGS_DEFAULT when not building the core. This means 3rd party
3582 extensions do not automatically benefit from the class attribute
3583 cache; they will have to explicitly add Py_TPFLAGS_HAVE_VERSION_TAG
3584 to their tp_flags field if they care. This is a backwards
3585 compatibility feature; in 3.0, all types will use the cache by
3586 default.
3587
Benjamin Petersonf647dc12008-08-20 01:27:30 +00003588- Keyword arguments can now follow starred arguments. (``f(a, *args,
3589 keyword=23)`` is now valid syntax.)
3590
Thomas Heller0ad5ae02008-08-19 19:25:04 +00003591- ctypes function pointers that are COM methods have a boolean True
3592 value again.
3593
Martin v. Löwisf91d46a2008-08-12 14:49:50 +00003594- Issue #3139: Make buffer-interface thread-safe wrt. PyArg_ParseTuple,
3595 by denying s# to parse objects that have a releasebuffer procedure,
3596 and introducing s*.
3597
Georg Brandl1e13ea92008-08-11 09:07:59 +00003598- Issue #3537: Fix an assertion failure when an empty but presized dict
3599 object was stored in the freelist.
3600
Mark Dickinsonb6467572008-08-04 21:30:09 +00003601- Issue #1481296: Make long(float('nan')) and int(float('nan')) raise
3602 ValueError consistently across platforms.
3603
Amaury Forgeot d'Arc39fd6722008-07-31 21:28:03 +00003604- Issue #3479: On platforms where sizeof(int) is smaller than sizeof(long)
3605 (64bit Unix, for example), unichr() would truncate its argument and return
3606 u'\x00' for unichr(2**32). Now it properly raises an OverflowError.
3607
Neal Norwitze7d8be82008-07-31 17:17:14 +00003608- Apply security patches from Apple.
3609
Amaury Forgeot d'Arc246daed2008-07-31 00:42:16 +00003610- Issue #2542: Now that issubclass() may call arbitrary code, ensure that
3611 PyErr_ExceptionMatches returns 0 when an exception occurs there.
3612
Antoine Pitrou92f82162008-07-25 22:22:08 +00003613- Issue #1819: function calls with several named parameters are now on
3614 average 35% faster (as measured by pybench).
3615
Amaury Forgeot d'Arce4921fe2008-07-21 22:00:38 +00003616- Issue #2378: An unexpected UnboundLocalError or NameError could appear when
3617 the python debugger steps into a class statement: the free variables (local
3618 variables defined in an outer scope) would be deleted from the outer scope.
3619
Gregory P. Smith0470bab2008-07-22 04:46:32 +00003620- Issue #2620: Overflow checking when allocating or reallocating memory
3621 was not always being done properly in some python types and extension
3622 modules. PyMem_MALLOC, PyMem_REALLOC, PyMem_NEW and PyMem_RESIZE have
3623 all been updated to perform better checks and places in the code that
3624 would previously leak memory on the error path when such an allocation
3625 failed have been fixed.

3628-------
3629
Hirokazu Yamamoto838c79f2008-08-20 13:14:07 +00003630- Issue #3612: Added some missing basic types in ctypes.wintypes.
3631
Benjamin Petersone977ad42008-08-20 01:42:01 +00003632- The methods ``is_in_tuple()``, ``is_vararg()``, and ``is_keywordarg()`` of
3633 symtable.Symbol have been deprecated for removal in 3.0 and the next release.
3634
Amaury Forgeot d'Arc351ffb82008-08-18 19:23:47 +00003635- Issue #2234: distutils failed for some versions of the cygwin compiler. The
3636 version reported by these tools does not necessarily follow the python
3637 version numbering scheme, so the module is less strict when parsing it.
3638
Nick Coghlanf70385a2008-08-18 12:42:46 +00003639- Issue #2235: Added Py3k warnings for types which will become unhashable
3640 under the stricter __hash__ inheritance rules in 3.0. Several types
3641 which did not meet the rules for hash invariants and were already
3642 unhashable in 3.0 have now been explicitly flagged as unhashable in
3643 2.6 as well (collections.Mapping, collections.Set, unittest.TestSuite,
3644 xml.dom.minidom.NamedNodeMap, numbers.Number, UserList.UserList)
3645
Brett Cannon88f801d2008-08-18 00:46:22 +00003646- Update __all__ for cookielib, csv, os, urllib2, and weakref to include things
3647 imported into the module but exposed as part of the module's API.
3648
Brett Cannon7b96f072008-08-18 00:41:11 +00003649- Remove an unneeded import of abc.ABCMeta from 'inspect'.
3650
Brett Cannon46225e72008-08-18 00:36:52 +00003651- Remove unneeded imports of 'sys' and 'warnings' from 'io'.

3654
Hirokazu Yamamoto41a81eb2008-08-17 13:10:46 +00003655- Issue #3575: Incremental decoder's decode function now takes bytearray
3656 by using 's*' instead of 't#'.
3657
Mark Dickinson3e4caeb2009-02-21 20:27:01 +00003658- Issue #2222: Fixed reference leak when occurred os.rename()
Hirokazu Yamamoto7f30a682008-08-17 09:46:56 +00003659 fails unicode conversion on 2nd parameter. (windows only)
3660
Georg Brandl222e2082010-08-01 22:27:39 +00003661- Issue #2464: urllib2 now supports a malformation in the URL received
Facundo Batista94f243a2008-08-17 03:38:39 +00003662 in a redirect.
3663
Brett Cannonabe423e2008-08-16 21:47:07 +00003664- Silence the DeprecationWarning raised when importing mimetools in
Brett Cannon721b1452008-08-16 22:00:27 +00003665 BaseHTTPServer, cgi (and rfc822), httplib.
Brett Cannonabe423e2008-08-16 21:47:07 +00003666
Facundo Batistaeb90b782008-08-16 14:44:07 +00003667- Issue #2776: fixed small issue when handling an URL with double slash
3668 after a 302 response in the case of not going through a proxy.
3669
Antoine Pitroub90a8be2008-08-15 21:03:21 +00003670- Issue #2676: in the email package, content-type parsing was hanging on
3671 pathological input because of quadratic or exponential behaviour of a
3672 regular expression.
3673
Antoine Pitrou11ec65d2008-08-14 21:04:30 +00003674- Issue #3476: binary buffered reading through the new "io" library is now
3675 thread-safe.
3676
Brett Cannonbf3157b2008-08-14 05:00:03 +00003677- Silence the DeprecationWarning of rfc822 when it is imported by mimetools
3678 since mimetools itself is deprecated. Because modules are cached, all
3679 subsequent imports of rfc822 will not raise a visible DeprecationWarning.
3680
Antoine Pitrou9fcd4b32008-08-11 17:21:36 +00003681- Issue #3134: shutil referenced undefined WindowsError symbol.
3682
Robert Schuppenies14646332008-08-10 11:01:53 +00003683- Issue #1342811: Fix leak in Tkinter.Menu.delete. Commands associated to
3684 menu entries were not deleted.
3685
Brett Cannon83e81842008-08-09 23:30:55 +00003686- Copied the implementation of reduce() to _functools.reduce() to have a
3687 version that did not raise a DeprecationWarning under -3.
3688
Antoine Pitrou76b8bee2008-08-09 17:27:23 +00003689- Issue #3205: When iterating over a BZ2File fails allocating memory, raise
3690 a MemoryError rather than silently stop the iteration.
3691
Guido van Rossum59ce9012008-08-09 14:55:34 +00003692- Issue #3487: sre "bytecode" validator. Passing invalid "re-bytecode"
3693 to _sre.compile() will now be rejected. This should not affect anybody
3694 since the re.compile() function never generates invalid re-bytecode.

3773
Georg Brandl3e483f62008-07-16 22:57:41 +00003774- Issue #3156: Fix inconsistent behavior of the bytearray type: all
3775 its methods now allow for items objects that can be converted to
3776 an integer using operator.index().
3777
Mark Dickinson64b7e502008-07-16 09:40:03 +00003778- Issue #3360: Fix incorrect parsing of '020000000000.0', which
3779 produced a ValueError instead of giving the correct float.
3780
Eric Smitha5fa5a22008-07-16 00:11:49 +00003781- Issue #3083: Add alternate (#) formatting for bin, oct, hex output
3782 for str.format(). This adds the prefix 0b, 0o, or 0x, respectively.
3783
Mark Dickinson7103aa42008-07-15 19:08:33 +00003784- Issue #3008: the float type has a new instance method 'float.hex'
3785 and a new class method 'float.fromhex' to convert floating-point
3786 numbers to and from hexadecimal strings, respectively.
3787
Nick Coghlan6d6bd442008-07-15 15:40:22 +00003788- Issue #2235: __hash__ is once again inherited by default. To allow
3789 collections.Hashable to remain meaningful in the presence of the
3790 default hash implementation (object.__hash__), it is now possible
3791 to explicit block inheritance of hash by setting __hash__=None at
3792 the Python level, or tp_hash=PyObject_HashNotImplemented at the C
3793 level.

Nick Coghlanb028f502008-07-13 14:52:36 +00003795- Issue #3221: Issue a RuntimeWarning instead of raising SystemError if
3796 the parent module cannot be found while performing an absolute import.
3797 This means that an incorrectly defined __package__ attribute will
3798 now only prevent relative imports in that module rather than causing
3799 all imports from that module to fail.
3800
Nick Coghlan14ff9942008-07-08 14:21:42 +00003801- Issue #2517: Allow unicode messages in Exceptions again by correctly

3811 another thread's dictionary.
3812
Mark Dickinson1ec2fcd2008-06-20 14:53:43 +00003813- Issue #3004: Minor change to slice.indices(): the start and stop
3814 arguments are now treated identically, making the behaviour easier
3815 to describe and understand. For example, slice(None, -10,
3816 1).indices(9) now returns (0, 0, 1) instead of (0, -1, 1), and
3817 slice(None, 10, -1).indices(10) returns (9, 9, -1) instead of (9,
3818 10, -1).

Georg Brandl278fc502008-07-19 12:46:12 +00003820- Issue #3219: Calling a function with repeated keyword arguments,
3821 f(a=2, a=23), would not cause a syntax error. This was a regression
3822 from 2.4 caused by the switch to the new compiler.

3861 both unnecessary (HTTP allows text content to be sent in several forms) and
Andrew M. Kuchlingcc3f2b12008-07-10 14:43:31 +00003862 wrong because the actual transmitted size could differ from the
Amaury Forgeot d'Arc0f7cddc2008-07-06 21:34:39 +00003863 content-length. The problem had been corrected in the 2.4 branch, but never

Nick Coghlanc060b0e2008-07-02 13:09:19 +00003879- Issue #3190: Pydoc now hides the automatic module attribute __package__ (the

4267
Brett Cannonb61d8012008-05-11 23:39:04 +00004268- ``Lib/lib-old`` is now added to sys.path.
4269
Ronald Oussoren5640ce22008-06-05 12:58:24 +00004270- On MacOS X it is now possible to install the framework in 64-bit
4271 mode or even as a 4-way universal binary (that is, PPC, i386,
Georg Brandl5cc774e2008-06-11 20:28:06 +00004272 PPC64 and x86_64 support in one binary).
Ronald Oussoren5640ce22008-06-05 12:58:24 +00004273
4274 This is controlled by the configure argument ``--with-universal-archs``:
4275
4276 - ``--with-universal-archs=all``: install 4-way universal
4277
4278 - ``--with-universal-archs=32-bit``: install 2-way universal, 32-bit (the default)
4279
4280 - ``--with-universal-archs=64-bit``: install 2-way universal, 64-bit
4281
4282 This option should be used in combination with ``--enable-universalsdk=``.
4283
4284 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 +00004293
4294- The PyString functions have been renamed to PyBytes. A batch of
4295 defines were added so that the linker still sees the original
4296 PyString names.

Georg Brandl3ee81df2008-05-17 18:14:43 +00004334- Issue #1631171: Re-implement the 'warnings' module in C (the
4335 original Python code has been kept as backup). This will allow for
4336 using the 'warning's machinery in such places as the parser where
4337 use of pure Python code is not possible. Both the ``showarning()``
4338 and ``formatwarning()`` gain an optional 'line' argument which is
4339 not called by default for backwards-compatibility reasons. Setting
4340 ``warnings.showwarning()`` to an implementation that lacks support
4341 for the ``line`` argument will raise a DeprecationWarning.

4365
Gregory P. Smithd59fefb2008-04-22 08:11:33 +00004366- The getpass module has been improved on Unix. It now uses /dev/tty
4367 by default and uses stderr instead of stdout. A GetPassWarning is
4368 issued when input echo cannot be controlled.
Gregory P. Smith41e30182008-04-21 21:31:08 +00004369

4380 implementation detail of the public ``types`` module, has been
4381 removed and replaced by pure python code.
Amaury Forgeot d'Arc02f33b42008-04-08 23:10:07 +00004382
Georg Brandl3ee81df2008-05-17 18:14:43 +00004383- Issue #2513: distutils on Windows is now capable of cross-compiling
Mark Hammond495cf992008-04-07 01:53:39 +00004384 extension modules between 32 and 64 bit platforms. See the distutls

4397 so the controlled environment will more closely mirror the typical
4398 script environment. This supports setup.py scripts that refer to
4399 data files.

Georg Brandl3ee81df2008-05-17 18:14:43 +00004404- Issue #2550: The approach used by client/server code for obtaining
4405 ports to listen on in network-oriented tests has been refined in an
4406 effort to facilitate running multiple instances of the entire
4407 regression test suite in parallel without issue.
4408 test_support.bind_port() has been fixed such that it will always
4409 return a unique port -- which wasn't always the case with the
4410 previous implementation, especially if socket options had been set
4411 that affected address reuse (i.e. SO_REUSEADDR, SO_REUSEPORT). The
4412 new implementation of bind_port() will actually raise an exception
4413 if it is passed an AF_INET/SOCK_STREAM socket with either the
4414 SO_REUSEADDR or SO_REUSEPORT socket option set. Furthermore, if
4415 available, bind_port() will set the SO_EXCLUSIVEADDRUSE option on
4416 the socket it's been passed. This currently only applies to
4417 Windows. This option prevents any other sockets from binding to the
4418 host/port we've bound to, thus removing the possibility of the
4419 'non-deterministic' behaviour, as Microsoft puts it, that occurs
4420 when a second SOCK_STREAM socket binds and accepts to a host/port
4421 that's already been bound by another socket. The optional preferred
4422 port parameter to bind_port() has been removed. Under no
4423 circumstances should tests be hard coding ports!
4424
4425 test_support.find_unused_port() has also been introduced, which will
4426 pass a temporary socket object to bind_port() in order to obtain an
4427 unused port. The temporary socket object is then closed and
4428 deleted, and the port is returned. This method should only be used
4429 for obtaining an unused port in order to pass to an external program
4430 (i.e. the -accept [port] argument to openssl's s_server mode) or as
4431 a parameter to a server-oriented class that doesn't give you direct
4432 access to the underlying socket used.
4433
4434 Finally, test_support.HOST has been introduced, which should be used
4435 for the host argument of any relevant socket calls (i.e. bind and
4436 connect).
Trent Nelsone41b0062008-04-08 23:47:30 +00004437
4438 The following tests were updated to following the new conventions:
Georg Brandl3ee81df2008-05-17 18:14:43 +00004439 test_socket, test_smtplib, test_asyncore, test_ssl, test_httplib,
Trent Nelsone41b0062008-04-08 23:47:30 +00004440 test_poplib, test_ftplib, test_telnetlib, test_socketserver,
4441 test_asynchat and test_socket_ssl.
4442
Georg Brandl3ee81df2008-05-17 18:14:43 +00004443 It is now possible for multiple instances of the regression test
4444 suite to run in parallel without issue.

Eric Smitha73fbe72008-02-23 03:09:44 +00004723- Added the future_builtins module, which contains hex() and oct().
4724 These are the PEP 3127 version of these functions, designed to be
4725 compatible with the hex() and oct() builtins from Python 3.0. They
4726 differ slightly in their output formats from the existing, unchanged
4727 Python 2.6 builtins. The expected usage of the future_builtins
4728 module is:
4729 from future_builtins import hex, oct
4730
Eric Smith7ef40bf2008-02-20 23:34:22 +00004731- Issue #1600: Modifed PyOS_ascii_formatd to use at most 2 digit
4732 exponents for exponents with absolute value < 100. Follows C99
4733 standard. This is a change on Windows, which would use 3 digits.
4734 Also, added 'n' to the formats that PyOS_ascii_formatd understands,
4735 so that any alterations it does to the resulting string will be
4736 available in stringlib/formatter.h (for float.__format__).
4737
Eric Smith5a3c1352008-02-19 13:21:56 +00004738- Implemented PEP 3101, Advanced String Formatting. This adds a new
4739 builtin format(); a format() method for str and unicode; a
4740 __format__() method to object, str, unicode, int, long, float, and
4741 datetime; the class string.Formatter; and the C API
4742 PyObject_Format().
4743
Georg Brandl3ee81df2008-05-17 18:14:43 +00004744- Fixed several potential crashes, all caused by specially crafted
4745 __del__ methods exploiting objects in temporarily inconsistent
4746 state.

4757 memory to the OS earlier.
Christian Heimes3b718a72008-02-14 12:47:33 +00004758
Georg Brandl3ee81df2008-05-17 18:14:43 +00004759- Issue #2045: Fix an infinite recursion triggered when printing a
4760 subclass of collections.defaultdict, if its default_factory is set
4761 to a bound method.
Amaury Forgeot d'Arcb01aa432008-02-08 00:56:02 +00004762
Christian Heimesf75dbef2008-02-08 00:11:31 +00004763- Fixed a minor memory leak in dictobject.c. The content of the free
4764 list was not freed on interpreter shutdown.
4765
Georg Brandl21e99f42010-03-07 15:23:59 +00004766- Limit free list of method and built-in function objects to 256

4770 functions ``PyInt_CompactFreeList`` and ``PyFloat_CompactFreeList``
Christian Heimes422051a2008-02-04 18:00:12 +00004771 to compact the internal free lists of pre-allocted ints and floats.
4772
Georg Brandl3ee81df2008-05-17 18:14:43 +00004773- Issue #1983: Fixed return type of fork(), fork1() and forkpty()
4774 calls. Python expected the return type int but the fork familie

Georg Brandl3ee81df2008-05-17 18:14:43 +00004786- Added ``PyType_ClearCache()`` and ``sys._clear_type_cache`` to clear
4787 the internal lookup cache for ref leak tests.
Christian Heimes908caac2008-01-27 23:34:59 +00004788
Georg Brandl3ee81df2008-05-17 18:14:43 +00004789- Patch #1473257: generator objects gain a gi_code attribute. This is
4790 the same object as the func_code attribute of the function that
4791 produced the generator.
Georg Brandl0cdf9a32008-01-26 14:14:20 +00004792
Georg Brandl3ee81df2008-05-17 18:14:43 +00004793- Issue #1920: "while 0" statements were completely removed by the
4794 compiler, even in the presence of an "else" clause, which is
4795 supposed to be run when the condition is false. Now the compiler
4796 correctly emits bytecode for the "else" suite.
Amaury Forgeot d'Arc31eaafe2008-01-24 22:59:25 +00004797
Guido van Rossumeead05f2008-01-24 18:21:02 +00004798- A few crashers fixed: weakref_in_del.py (issue #1377858);
4799 loosing_dict_ref.py (issue #1303614, test67.py);
4800 borrowed_ref_[34].py (not in tracker).
4801
Vinay Sajipd7cf32e2008-01-24 12:43:33 +00004802- Issue #1069410: The "can't load dll" message box on Windows is
Christian Heimesb2302ba2008-01-23 17:15:06 +00004803 suppressed while an extension is loaded by calling SetErrorMode in
4804 dynload_win.c. The error is still reported properly.
4805
Georg Brandl3ee81df2008-05-17 18:14:43 +00004806- Issue #1915: Python compiles with --enable-unicode=no again. However
Christian Heimes082c9b02008-01-23 14:20:50 +00004807 several extension methods and modules do not work without unicode
4808 support.
4809
Georg Brandl26543b12008-01-21 18:36:51 +00004810- Issue #1882: when compiling code from a string, encoding cookies in the
4811 second line of code were not always recognized correctly.
4812
Georg Brandl14404b62008-01-19 19:27:05 +00004813- Issue #1679: "0x" was taken as a valid integer literal.
4814
Georg Brandl6caad7d2008-01-26 14:19:22 +00004815- Issue #1865: ``bytes`` as an alias for ``str`` and b"" as an alias "" were
Christian Heimes288e89a2008-01-18 18:24:07 +00004816 added.
4817
Christian Heimesc94e2b52008-01-14 04:13:37 +00004818- sys.float_info / PyFloat_GetInfo: The floating point information
4819 object was converted from a dict to a specialized structseq object.
4820
Georg Brandl3ee81df2008-05-17 18:14:43 +00004821- Patch #1816: Added sys.flags structseq. It exposes the status of
4822 most command line arguments and PYTHON* environment variables.
Christian Heimesf31b69f2008-01-14 03:42:48 +00004823
Georg Brandl3ee81df2008-05-17 18:14:43 +00004824- Objects/structseq.c: Implemented new structseq representation. The
4825 patch makes structseqs (e.g. the return value of os.stat) more
4826 readable.
Christian Heimes9c201962008-01-14 03:33:52 +00004827
Georg Brandl3ee81df2008-05-17 18:14:43 +00004828- Patch #1700288: added a type attribute cache that caches method
4829 accesses, resulting in speedups in heavily object-oriented code.
Amaury Forgeot d'Arce4c270c2008-01-14 00:29:41 +00004830
Neal Norwitz3fc15b82008-01-10 05:42:58 +00004831- Bug #1776: __import__() no longer accepts filenames on any platform.
4832 The first parameter to __import__() must be a valid module name.
Christian Heimes3403f152008-01-09 19:56:33 +00004833
Georg Brandlaed6c662008-01-07 17:25:53 +00004834- Patch #1668: renamed THREADDEBUG envvar to PYTHONTHREADDEBUG.
4835
Georg Brandl3ee81df2008-05-17 18:14:43 +00004836- Patch #602345: Add -B command line option, PYTHONDONTWRITEBYTECODE
4837 envvar and sys.dont_write_bytecode attribute. All these can be set
4838 to forbid Python to attempt to write compiled bytecode files.
Georg Brandl2da0fce2008-01-07 17:09:35 +00004839
Georg Brandl3ee81df2008-05-17 18:14:43 +00004840- Improve some exception messages when Windows fails to load an
4841 extension module. Now we get for example '%1 is not a valid Win32
4842 application' instead of 'error code 193'.

Christian Heimes0a8143f2007-12-18 23:22:54 +00004849- Issue #1635: Platform independent creation and representation of NaN
Georg Brandl3ee81df2008-05-17 18:14:43 +00004850 and INF. float("nan"), float("inf") and float("-inf") now work on
4851 every platform with IEEE 754 semantics.
Christian Heimes0a8143f2007-12-18 23:22:54 +00004852
Georg Brandl3ee81df2008-05-17 18:14:43 +00004853- Compiler now generates simpler and faster code for dictionary
4854 literals. The oparg for BUILD_MAP now indicates an estimated
4855 dictionary size. There is a new opcode, STORE_MAP, for adding
4856 entries to the dictionary.

Georg Brandl3ee81df2008-05-17 18:14:43 +00004885- Patch #1739468: Directories and zipfiles containing a __main__.py
4886 file can now be directly executed by passing their name to the
4887 interpreter. The directory/zipfile is automatically inserted as the
4888 first entry in sys.path.

Georg Brandl3ee81df2008-05-17 18:14:43 +00004890- Issue #1265: Fix a problem with sys.settrace, if the tracing
4891 function uses a generator expression when at the same time the
4892 executed code is closing a paused generator.
Amaury Forgeot d'Arc0d75f092007-11-13 21:54:28 +00004893
Raymond Hettinger1760c8a2007-11-08 02:52:43 +00004894- sets and frozensets now have an isdisjoint() method.
4895
Raymond Hettinger3f8caa32007-10-24 01:28:33 +00004896- optimize the performance of builtin.sum().
4897
Neal Norwitz44f326e2007-10-05 05:29:17 +00004898- Fix warnings found by the new version of the Coverity checker.
4899
Georg Brandl21e99f42010-03-07 15:23:59 +00004900- The enumerate() built-in function is no longer bounded to sequences
Georg Brandl3ee81df2008-05-17 18:14:43 +00004901 smaller than LONG_MAX. Formerly, it raised an OverflowError. Now,
4902 automatically shifts from ints to longs.
Raymond Hettinger8f669372007-10-03 21:18:11 +00004903
Georg Brandl3ee81df2008-05-17 18:14:43 +00004904- Issue #1686386: Tuple's tp_repr did not take into account the
4905 possibility of having a self-referential tuple, which is possible
4906 from C code. Nor did object's tp_str consider that a type's tp_str
4907 could do something that could lead to an inifinite recursion.
4908 Py_ReprEnter() and Py_EnterRecursiveCall(), respectively, fixed the
4909 issues.
Brett Cannon0b14f242007-09-30 19:45:10 +00004910
Georg Brandl3ee81df2008-05-17 18:14:43 +00004911- Issue #1164: It was possible to trigger deadlock when using the
4912 'print' statement to write to a file since the GIL was not released
4913 as needed. Now PyObject_Print() does the right thing along with
4914 various tp_print implementations of the built-in types and those in
4915 the collections module.
Brett Cannon01531592007-09-17 03:28:34 +00004916
Georg Brandl3ee81df2008-05-17 18:14:43 +00004917- Issue #1147: Exceptions were directly allowing string exceptions in
4918 their throw() method even though string exceptions no longer
4919 allowed.
Brett Cannon4c20bc42007-09-11 21:02:28 +00004920
Georg Brandl3ee81df2008-05-17 18:14:43 +00004921- Issue #1096: Prevent a segfault from getting the repr of a very
4922 deeply nested list by using the recursion counter.
Brett Cannona0c05512007-09-10 21:38:27 +00004923
Brett Cannon1e534b52007-09-07 04:18:30 +00004924- Issue #1202533: Fix infinite recursion calls triggered by calls to
Georg Brandl3ee81df2008-05-17 18:14:43 +00004925 PyObject_Call() never calling back out to Python code to trigger
4926 recursion depth updates/checks. Required the creation of a static
4927 RuntimeError instance in case normalizing an exception put the
4928 recursion check value past its limit. Fixes crashers
4929 infinite_rec_(1|2|4|5).py.
Brett Cannon1e534b52007-09-07 04:18:30 +00004930

Neal Norwitz0ac60192007-05-27 04:08:54 +00004944- Add new attribute names for function objects. All the func_* become
Georg Brandl3ee81df2008-05-17 18:14:43 +00004945 __*__ attributes. (Some already existed, e.g., __doc__ and
4946 __name__.)
Neal Norwitz0ac60192007-05-27 04:08:54 +00004947
Neal Norwitz8b2bfbc2007-05-23 06:35:32 +00004948- Add -3 option to the interpreter to warn about features that are
4949 deprecated and will be changed/removed in Python 3.0.
4950
Georg Brandl2134e752007-05-21 20:34:16 +00004951- Patch #1686487: you can now pass any mapping after '**' in function
4952 calls.
4953
Collin Winter62903052007-05-18 23:11:24 +00004954- except clauses may now be spelled either "except E, target:" or
Georg Brandl3ee81df2008-05-17 18:14:43 +00004955 "except E as target:". This is to provide forwards compatibility
4956 with Python 3.0.

Brett Cannon229cee22007-05-05 01:34:02 +00004958- Deprecate BaseException.message as per PEP 352.
4959
Georg Brandl3ee81df2008-05-17 18:14:43 +00004960- Issue #1303614: don't expose object's __dict__ when the dict is
Georg Brandl21e99f42010-03-07 15:23:59 +00004961 inherited from a built-in base.
Armin Rigo9790a272007-05-02 19:23:31 +00004962
Vinay Sajip8549ce32007-05-06 17:53:37 +00004963- When __slots__ are set to a unicode string, make it work the same as
Neal Norwitzcbd9ee62007-04-14 05:25:50 +00004964 setting a plain string, ie don't expand to single letter identifiers.
4965
Raymond Hettinger13936692007-04-11 18:40:58 +00004966- Request #1191699: Slices can now be pickled.
4967
Raymond Hettinger4db5fe92007-04-12 04:10:00 +00004968- Request #1193128: str.translate() now allows a None argument for
4969 translations that only remove characters without re-mapping the
4970 remaining characters.
4971
Georg Brandl5cb76c12007-03-21 09:00:39 +00004972- Patch #1682205: a TypeError while unpacking an iterable is no longer
4973 masked by a generic one with the message "unpack non-sequence".
4974
Neal Norwitzaa754b72007-03-21 06:39:48 +00004975- Remove unused file Python/fmod.c.
4976
Guido van Rossum143b5642007-03-23 04:58:42 +00004977- Bug #1683368: The object.__init__() and object.__new__() methods are
4978 now stricter in rejecting excess arguments. The only time when
4979 either allows excess arguments is when it is not overridden and the
4980 other one is. For backwards compatibility, when both are
4981 overridden, it is a deprecation warning (for now; maybe a Py3k
Guido van Rossum234b1ff2007-03-23 19:39:01 +00004982 warning later). Also, type.__init__() insists on the same signature
4983 as supported by type.__new__().
Guido van Rossum143b5642007-03-23 04:58:42 +00004984
Georg Brandl3ee81df2008-05-17 18:14:43 +00004985- Patch #1675423: PyComplex_AsCComplex() now tries to convert an
4986 object to complex using its __complex__() method before falling back
4987 to the __float__() method. Therefore, the functions in the cmath
4988 module now can operate on objects that define a __complex__()
4989 method.

5006
Georg Brandl7b9c5552007-03-12 14:30:05 +00005007- Bug #1678647: write a newline after printing an exception in any
5008 case, even when converting the value to a string failed.
5009
Georg Brandl871f1bc2007-03-12 13:17:36 +00005010- The dir() function has been extended to call the __dir__() method on
Georg Brandl3ee81df2008-05-17 18:14:43 +00005011 its argument, if it exists. If not, it will work like before. This
5012 allows customizing the output of dir() in the presence of a
5013 __getattr__().

Georg Brandl4e933132006-09-06 20:05:58 +00005128- Bug #1542051: Exceptions now correctly call PyObject_GC_UnTrack.

Georg Brandl3ee81df2008-05-17 18:14:43 +00005146 generator expressions (x for x, in ... ) works again. Fixing this
5147 problem required changing the .pyc magic number. This means that
5148 .pyc files generated before 2.5c2 will be regenerated.

Guido van Rossum8bc09652008-02-21 18:18:37 +00005187- Removed uses of dict.has_key() from distutils, and uses of

Georg Brandl3ee81df2008-05-17 18:14:43 +00005537 the client's request was successfully received, understood, and

Georg Brandl3ee81df2008-05-17 18:14:43 +00005578 AttributeError instead of an IOError when the server's response

5670 TestCase and TestSuite subclasses (not instances) are no longer

Georg Brandl3ee81df2008-05-17 18:14:43 +00006063 time so that opening a database previously created with the DB_DUP
6064 or DB_DUPSORT flag set will keep the proper behavior on subsequent
6065 opens. Specifically: dictionary assignment to a DB object will
6066 replace all values for a given key when the database allows
6067 duplicate values. DB users should use DB.put(k, v) when they want
6068 to store duplicates; not DB[k] = v.

6075 characters with ASCII value less than 32. Also, it correctly quotes
6076 dots only if they occur on a single line, as opposed to the previous
6077 behavior of quoting dots if they are the second character of any
6078 line.
