763

765 handles non-blocking readinto() returning None correctly.

768 SSLSocket.sendto() to match the corresponding socket methods. Also,
769 fix various SSLSocket methods to raise socket.error rather than an
770 unhelpful TypeError when called on an unconnected socket. Original patch
771 by Andrew Bennetts.
772
Raymond Hettinger74f869e2010-09-13 22:14:36 +0000773- Issue #9826: OrderedDict.__repr__ can now handle self-referential

780
Raymond Hettinger20397532010-09-12 02:11:45 +0000781- Issue #9825: removed __del__ from the definition of collections.OrderedDict.
782 This prevents user-created self-referencing ordered dictionaries from
783 becoming permanently uncollectable GC garbage. The downside is that
784 removing __del__ means that the internal doubly-linked list has to wait for
785 GC collection rather than freeing memory immediately when the refcnt drops
786 to zero.
787
Raymond Hettingerffd2a422010-09-10 10:47:22 +0000788- Issue #9816: random.Random.jumpahead(n) did not produce a sufficiently
Victor Stinnerd2f6ae62010-10-12 22:53:51 +0000789 different internal state for small values of n. Fixed by salting the
Raymond Hettingerffd2a422010-09-10 10:47:22 +0000790 value.
791
Antoine Pitrouc818ed42010-09-07 21:40:25 +0000792- Issue #9792: In case of connection failure, socket.create_connection()
793 would swallow the exception and raise a new one, making it impossible
794 to fetch the original errno, or to filter timeout errors. Now the
795 original error is re-raised.
796
Antoine Pitrouf4f61712010-09-07 16:34:47 +0000797- Issue #9758: When fcntl.ioctl() was called with mutable_flag set to True,
798 and the passed buffer was exactly 1024 bytes long, the buffer wouldn't
799 be updated back after the system call. Original patch by Brian Brazil.
800
Antoine Pitroudca9de92010-09-04 17:52:26 +0000801- Issue #1100562: Fix deep-copying of objects derived from the list and
802 dict types. Patch by Michele Orrù and Björn Lindqvist.
803

805 ConfigParser.write.
806
Daniel Stutzbach66c981b2010-08-31 20:29:39 +0000807- Issue #808164: Fixed socket.close to avoid references to globals, to
808 avoid issues when socket.close is called from a __del__ method.
809
Terry Reedyd2d2ae92010-11-11 23:22:19 +0000810- Issue #2986: difflib.SequenceMatcher gets a new parameter, autojunk, which

812 heuristic. Patch by Terry Reedy and Eli Bendersky
813
Senthil Kumaran7e8fd5e2010-08-26 06:20:13 +0000814- Issue #8797: urllib2 does a retry for Basic Authentication failure instead of
815 falling into recursion.
816
R. David Murray7c4bf552010-08-25 01:45:57 +0000817- Issue #1194222: email.utils.parsedate now returns RFC2822 compliant four
818 character years even if the message contains RFC822 two character years.
819
Daniel Stutzbach91287322010-08-24 21:09:30 +0000820- Issue #8750: Fixed MutableSet's methods to correctly handle
821 reflexive operations, namely x -= x and x ^= x.
822
Victor Stinnercaafd772010-09-08 10:51:01 +0000823- Issue #9129: smtpd.py is vulnerable to DoS attacks deriving from missing

827 errors.

832 module now correctly return a set. (Patch by Eli Bendersky.)
833
Antoine Pitrou3ebaed62010-08-21 19:17:25 +0000834- Issue #9617: Signals received during a low-level write operation aren't
835 ignored by the buffered IO layer anymore.
836
Benjamin Peterson52c36052010-08-21 03:03:22 +0000837- Issue #2521: Use weakrefs on for caching in the abc module, so that classes
838 are not held onto after they are deleted elsewhere.
839
Raymond Hettingera54b2da2010-08-17 19:03:06 +0000840- Issue #9626: the view methods for collections.OrderedDict() were returning
841 the unordered versions inherited from dict. Those methods are now
842 overridden to provide ordered views.
843
Éric Araujo0389ae62010-08-14 03:07:46 +0000844- Issue #8688: MANIFEST files created by distutils now include a magic
845 comment indicating they are generated. Manually maintained MANIFESTs
846 without this marker will not be overwritten or removed.
847
Antoine Pitroue1436d12010-08-12 15:25:51 +0000848- Issue #7467: when reading a file from a ZIP archive, its CRC is checked

850 case in Python 2.5 and earlier).
851
Antoine Pitroucb4f47c2010-08-11 13:40:17 +0000852- Issue #9550: a BufferedReader could issue an additional read when the
853 original read request had been satisfied, which could block indefinitely
854 when the underlying raw IO channel was e.g. a socket. Report and original
855 patch by Jason V. Miller.
856
Fred Drake0a1fa0e2010-08-10 13:09:54 +0000857- Issue #9551: Don't raise TypeError when setting the value to None for
858 SafeConfigParser instances constructed with allow_no_value == True.
859
Antoine Pitrou8cdede42010-08-10 00:04:13 +0000860- Issue #6915: Under Windows, os.listdir() didn't release the Global

877 behavior was wrong.

Ezio Melottiab2eb0e2010-06-05 19:21:32 +00001245- Issue #8271: during the decoding of an invalid UTF-8 byte sequence, only the
1246 start byte and the continuation byte(s) are now considered invalid, instead
1247 of the number of bytes specified by the start byte.
1248 E.g.: '\xf1\x80AB'.decode('utf-8', 'replace') now returns u'\ufffdAB' and
1249 replaces with U+FFFD only the start byte ('\xf1') and the continuation byte
1250 ('\x80') even if '\xf1' is the start byte of a 4-bytes sequence.
1251 Previous versions returned a single u'\ufffd'.

Mark Dickinson4ca7c3c2010-05-30 13:18:10 +00001259- Issue #8748: Fix two issues with comparisons between complex and integer
1260 objects. (1) The comparison could incorrectly return True in some cases
1261 (2**53+1 == complex(2**53) == 2**53), breaking transivity of equality.
1262 (2) The comparison raised an OverflowError for large integers, leading
1263 to unpredictable exceptions when combining integers and complex objects
1264 in sets or dicts.

Georg Brandlfee0f442010-05-22 21:26:21 +00001457- Issue #8567: Fix precedence of signals in Decimal module: when a Decimal
1458 operation raises multiple signals and more than one of those signals is
1459 trapped, the specification determines the order in which the signals should be
1460 handled. In many cases this order wasn't being followed, leading to the wrong
1461 Python exception being raised.

1647 with a non-empty format string. This is an effort to future-proof user
1648 code. If a derived class does not currently implement __format__ but later
1649 adds its own __format__, it would most likely break user code that had
Antoine Pitrou01a196a2011-01-02 20:05:11 +00001650 supplied a format string. This will be changed to a DeprecationWarning in
Georg Brandlfee0f442010-05-22 21:26:21 +00001651 Python 3.3 and it will be an error in Python 3.4.

Georg Brandlfee0f442010-05-22 21:26:21 +00001701- Issue #7279: Comparisons involving a Decimal signaling NaN now signal
1702 InvalidOperation instead of returning False. (Comparisons involving a quiet
1703 NaN are unchanged.) Also, Decimal quiet NaNs are now hashable; Decimal
1704 signaling NaNs remain unhashable.

Georg Brandlfee0f442010-05-22 21:26:21 +00001706- Issue #2531: Comparison operations between floats and Decimal instances now
1707 return a result based on the numeric values of the operands; previously they
1708 returned an arbitrary result based on the relative ordering of id(float) and
1709 id(Decimal).

Barry Warsawf7f2d6f2010-03-31 21:07:16 +00001711- Issue #8233: When run as a script, py_compile.py optionally takes a single
Georg Brandlfee0f442010-05-22 21:26:21 +00001712 argument `-` which tells it to read files to compile from stdin. Each line is
1713 read on demand and the named file is compiled immediately. (Original patch by
1714 Piotr Ożarowski).

1724 Fractions instance now raise TypeError instead of returning True/False. This
1725 makes Fraction <=> complex comparisons consistent with int <=> complex, float
1726 <=> complex, and complex <=> complex comparisons.

Georg Brandlba83f822010-03-14 09:50:54 +00001830- Issue #1530559: When passing a non-integer argument to struct.pack with *any*
1831 integer format code (one of 'bBhHiIlLqQ'), struct.pack attempts to use the

1835 the set of integer codes for which it was used differed between native packing
1836 and standard packing.)

Georg Brandlba83f822010-03-14 09:50:54 +00002144 file position when calling `truncate()`. It would previously change the file
2145 position to the given argument, which goes against the tradition of

2149 class used to represent files stored inside an archive. The new
2150 implementation is significantly faster and can be wrapped in a

2152 where interleaved calls to ``read()`` and ``readline()`` give wrong results.

2248
Mark Dickinson1b34d252010-01-01 17:27:30 +00002249- Issue #5080: A number of functions and methods previously produced a
Georg Brandlba83f822010-03-14 09:50:54 +00002250 DeprecationWarning when passed a float argument where an integer was expected.
2251 These functions and methods now raise TypeError instead. The majority of the
2252 effects of this change are in the extension modules, but some core functions
2253 and methods are affected: notably the 'chr', 'range' and 'xrange' builtins,
2254 and many unicode/str methods.

Georg Brandlba83f822010-03-14 09:50:54 +00002416- Issue #7419: ``locale.setlocale()`` could crash the interpreter on Windows
2417 when called with invalid values.
Amaury Forgeot d'Arcd7288712009-12-01 21:51:04 +00002418
Georg Brandlba83f822010-03-14 09:50:54 +00002419- Issue #3382: 'F' formatting for float and complex now convert the result to
2420 upper case. This only affects 'inf' and 'nan', since 'f' no longer converts
2421 to 'g' for large values.
Amaury Forgeot d'Arcd7288712009-12-01 21:51:04 +00002422
Georg Brandlba83f822010-03-14 09:50:54 +00002423- Remove switch from "%f" formatting to "%g" formatting for floats larger than
2424 1e50 in absolute value.
Mark Dickinson9dd5e162009-11-23 20:54:09 +00002425
Georg Brandlba83f822010-03-14 09:50:54 +00002426- Remove restrictions on precision when formatting floats. E.g., "%.120g" %
2427 1e-100 used to raise OverflowError, but now gives the requested 120
2428 significant digits instead.
Mark Dickinson18cfada2009-11-23 18:46:41 +00002429
Georg Brandlba83f822010-03-14 09:50:54 +00002430- Add Py3k warnings for parameter names in parentheses.

Benjamin Peterson89b1a5c2009-11-19 22:58:01 +00002433
Georg Brandlba83f822010-03-14 09:50:54 +00002434- Issue #7085: Fix crash when importing some extensions in a thread on MacOSX
2435 10.6.
Ronald Oussoren315cd0c2009-11-19 16:25:21 +00002436
Georg Brandlba83f822010-03-14 09:50:54 +00002437- Issue #7117: ``repr(x)`` for a float x returns a result based on the shortest
2438 decimal string that's guaranteed to round back to x under correct rounding
2439 (with round-half-to-even rounding mode). Previously it gave a string based on
2440 rounding x to 17 decimal digits. repr(x) for a complex number behaves
2441 similarly. On platforms where the correctly-rounded strtod and dtoa code is
2442 not supported (see below), repr is unchanged.
Mark Dickinsonb678de82009-11-19 18:41:49 +00002443
Georg Brandlba83f822010-03-14 09:50:54 +00002444- Issue #7117: On almost all platforms: float-to-string and string-to-float
2445 conversions within Python are now correctly rounded. Places these conversions
2446 occur include: str for floats and complex numbers; the float and complex
2447 constructors; old-style and new-style numeric formatting; serialization and
2448 deserialization of floats and complex numbers using marshal, pickle and json;
2449 parsing of float and imaginary literals in Python code; Decimal-to-float
2450 conversion.
Mark Dickinsonb678de82009-11-19 18:41:49 +00002451
Georg Brandlba83f822010-03-14 09:50:54 +00002452 The conversions use a Python-adapted version of David Gay's well-known dtoa.c,
2453 providing correctly-rounded strtod and dtoa C functions. This code is
2454 supported on Windows, and on Unix-like platforms using gcc, icc or suncc as
2455 the C compiler. There may be a small number of platforms on which correct
2456 operation of this code cannot be guaranteed, so the code is not used: notably,
2457 this applies to platforms where the C double format is not IEEE 754 binary64,
2458 and to platforms on x86 hardware where the x87 FPU is set to 64-bit precision
2459 and Python's configure script is unable to determine how to change the FPU
2460 precision. On these platforms conversions use the platform strtod and dtoa,
2461 as before.
Mark Dickinsonb678de82009-11-19 18:41:49 +00002462
Georg Brandlba83f822010-03-14 09:50:54 +00002463- Issue #7117: Backport round implementation from Python 3.x. ``round()`` now
2464 uses the correctly-rounded string <-> float conversions described above (when
2465 available), and so produces correctly rounded results that will display nicely
2466 under the float repr. There are two related small changes: (1) round now
2467 accepts any class with an ``__index__()`` method for its second argument (but
2468 no longer accepts floats for the second argument), and (2) an excessively
2469 large second integer argument (e.g., ``round(1.234, 10**100)``) no longer
2470 raises an exception.

Philip Jenveyfab8be22009-11-17 02:42:26 +00002472- Issue #1757126: Fix the cyrillic-asian alias for the ptcp154 encoding.
2473
Georg Brandlba83f822010-03-14 09:50:54 +00002474- Fix several issues with ``compile()``. The input can now contain Windows and
2475 Mac newlines and is no longer required to end in a newline.
Benjamin Petersone36199b2009-11-12 23:39:44 +00002476

Amaury Forgeot d'Arcd0052d12009-10-06 19:56:32 +00002505- Issue #1571184: The Unicode database contains properties for more characters.
2506 The tables for code points representing numeric values, white spaces or line
2507 breaks are now generated from the official Unicode Character Database files,
2508 and include information from the Unihan.txt file.

Georg Brandlba83f822010-03-14 09:50:54 +00002617- Issue #5920: For ``float.__format__()``, change the behavior with the empty
2618 presentation type (that is, not one of 'e', 'f', 'g', or 'n') to be like 'g'
2619 but with at least one decimal point and with a default precision
2620 of 12. Previously, the behavior the same but with a default precision of 6.
2621 This more closely matches ``str()``, and reduces surprises when adding
2622 alignment flags to the empty presentation type. This also affects the new
2623 complex.__format__ in the same way.

Georg Brandlba83f822010-03-14 09:50:54 +00002632- Issue #1588: Add complex.__format__. For example, ``format(complex(1, 2./3),
2633 '.5')`` now produces a sensible result.
Eric Smith9139cc62009-04-30 00:58:58 +00002634
Georg Brandlba83f822010-03-14 09:50:54 +00002635- Issue #5864: Fix empty format code formatting for floats so that it never
2636 gives more than the requested number of significant digits.
Mark Dickinson92fcc9c2009-04-29 20:41:00 +00002637
Georg Brandlba83f822010-03-14 09:50:54 +00002638- Issue #5793: Rationalize isdigit / isalpha / tolower, etc. Includes new

2642 not their own uppercase.
Martin v. Löwis99f27792009-04-26 00:53:18 +00002643
Eric Smith068f0652009-04-25 21:40:15 +00002644- Issue #5835: Deprecate PyOS_ascii_formatd and replace it with
2645 _PyOS_double_to_string or PyOS_double_to_string.
2646
Benjamin Peterson5083dc52009-04-25 00:41:22 +00002647- Issue #5283: Setting __class__ in __del__ caused a segfault.
2648
Georg Brandlba83f822010-03-14 09:50:54 +00002649- Issue #5816: ``complex(repr(z))`` now recovers z exactly, even when z involves
2650 nans, infs or negative zeros.

Georg Brandlba83f822010-03-14 09:50:54 +00002658- Issue #5772: For float.__format__, don't add a trailing ".0" if we're using no
2659 type code and we have an exponent.
Eric Smithaca19e62009-04-22 13:29:05 +00002660
Georg Brandlba83f822010-03-14 09:50:54 +00002661- Issue #3166: Make long -> float (and int -> float) conversions correctly

Georg Brandlba83f822010-03-14 09:50:54 +00002667- Issue #1869: Fix a couple of minor round() issues. ``round(5e15+1)`` was
2668 giving 5e15+2; ``round(-0.0)`` was losing the sign of the zero.

Antoine Pitrouf8387af2009-03-23 18:41:45 +00002687- Issue #4688: Add a heuristic so that tuples and dicts containing only
Georg Brandlba83f822010-03-14 09:50:54 +00002688 untrackable objects are not tracked by the garbage collector. This can reduce
2689 the size of collections and therefore the garbage collection overhead on
2690 long-running programs, depending on their particular use of datatypes.
Antoine Pitrouf8387af2009-03-23 18:41:45 +00002691
Georg Brandlba83f822010-03-14 09:50:54 +00002692- Issue #5512: Rewrite PyLong long division algorithm (x_divrem) to improve its

2694 150% faster.
Mark Dickinson0b666bf2009-03-23 18:25:13 +00002695
Georg Brandlba83f822010-03-14 09:50:54 +00002696- Issue #4258: Make it possible to use base 2**30 instead of base 2**15 for the
2697 internal representation of integers, for performance reasons. Base 2**30 is
2698 enabled by default on 64-bit machines. Add --enable-big-digits option to
2699 configure, which overrides the default. Add sys.long_info structseq to
2700 provide information about the internal format.
Mark Dickinsonefc82f72009-03-20 15:51:55 +00002701
Benjamin Peterson6ffe8522009-03-18 20:52:15 +00002702- Issue #4034: Fix weird attribute error messages of the traceback object. (As a
2703 result traceback.__members__ no longer exists.)
2704
Georg Brandlba83f822010-03-14 09:50:54 +00002705- Issue #4474: PyUnicode_FromWideChar now converts characters outside the BMP to
2706 surrogate pairs, on systems with sizeof(wchar_t) == 4 and sizeof(Py_UNICODE)
2707 == 2.
Mark Dickinson6b265f12009-03-18 16:07:26 +00002708
Georg Brandlba83f822010-03-14 09:50:54 +00002709- Issue #5237: Allow auto-numbered fields in str.format(). For example: ``'{}
2710 {}'.format(1, 2) == '1 2'``.
Eric Smith6f42edb2009-03-14 11:57:26 +00002711
Georg Brandlba83f822010-03-14 09:50:54 +00002712- Issue #3652: Make the 'line' argument for ``warnings.showwarning()`` a
Brett Cannon6c4cff02009-03-11 04:51:06 +00002713 requirement. Means the DeprecationWarning from Python 2.6 can go away.
2714
Georg Brandlba83f822010-03-14 09:50:54 +00002715- Issue #5247: Improve error message when unknown format codes are used when
2716 using ``str.format()`` with str, unicode, long, int, and float arguments.
Eric Smithe9fb6862009-02-20 14:02:36 +00002717
Georg Brandlba83f822010-03-14 09:50:54 +00002718- Running Python with the -3 option now also warns about classic division for
2719 ints and longs.
Raymond Hettinger08259e82009-02-18 23:10:19 +00002720
Georg Brandlba83f822010-03-14 09:50:54 +00002721- Issue #5260: Long integers now consume less memory: average saving is 2 bytes
2722 per long on a 32-bit system and 6 bytes per long on a 64-bit system.
Mark Dickinson2ffb26f2009-02-15 10:13:41 +00002723
Antoine Pitrou76a4b892009-02-13 13:52:33 +00002724- Issue #5186: Reduce hash collisions for objects with no __hash__ method by
2725 rotating the object pointer by 4 bits to the right.
2726
Georg Brandlba83f822010-03-14 09:50:54 +00002727- Issue #4575: Fix Py_IS_INFINITY macro to work correctly on x87 FPUs: it now
2728 forces its argument to double before testing for infinity.
Mark Dickinsonc97c9092009-02-09 14:18:43 +00002729
Benjamin Petersone18ef192009-01-20 14:21:16 +00002730- Issue #4978: Passing keyword arguments as unicode strings is now allowed.
2731
Georg Brandl29c6a282009-04-05 20:23:13 +00002732- Issue #1242657: the __len__() and __length_hint__() calls in several tools
Raymond Hettingerb5163702009-02-02 21:50:13 +00002733 were suppressing all exceptions. These include list(), filter(), map(),
2734 zip(), and bytearray().
2735
Benjamin Peterson596d3062009-01-19 15:42:23 +00002736- os.ftruncate raises OSErrors instead of IOErrors for consistency with other os
2737 functions.
2738
Benjamin Peterson5848d1f2009-01-19 00:08:08 +00002739- Issue #4991: Passing invalid file descriptors to io.FileIO now raises an
2740 OSError.
2741
Amaury Forgeot d'Arca18392a2009-01-13 23:19:08 +00002742- Issue #4807: Port the _winreg module to Windows CE.
2743
Georg Brandlba83f822010-03-14 09:50:54 +00002744- Issue #4935: The overflow checking code in the expandtabs() method common to
2745 str, bytes and bytearray could be optimized away by the compiler, letting the
2746 interpreter segfault instead of raising an error.
Antoine Pitrouc2f02212009-01-13 23:13:52 +00002747
Amaury Forgeot d'Arca40d5732009-01-12 23:36:55 +00002748- Issue #3720: Fix a crash when an iterator modifies its class and removes its
2749 __next__ method.
2750

2754
Antoine Pitrou4c5ecb72009-01-09 21:40:55 +00002755- Issue #4074: Change the criteria for doing a full garbage collection (i.e.
2756 collecting the oldest generation) so that allocating lots of objects without
2757 destroying them does not show quadratic performance. Based on a proposal by
Benjamin Petersond50a5d52009-07-13 00:03:20 +00002758 Martin von Löwis at
Antoine Pitrou4c5ecb72009-01-09 21:40:55 +00002759 http://mail.python.org/pipermail/python-dev/2008-June/080579.html.

2762
Georg Brandlba83f822010-03-14 09:50:54 +00002763- Issue #1180193: When importing a module from a .pyc (or .pyo) file with an
2764 existing .py counterpart, override the co_filename attributes of all code
2765 objects if the original filename is obsolete (which can happen if the file has
2766 been renamed, moved, or if it is accessed through different paths). Patch by
2767 Ziga Seilnacht and Jean-Paul Calderone.
Antoine Pitroue96d4ea2009-01-06 18:10:47 +00002768
Georg Brandlba83f822010-03-14 09:50:54 +00002769- Issue #4075: Use ``OutputDebugStringW()`` in Py_FatalError.

Hirokazu Yamamoto99a1b202009-01-01 15:45:39 +00002771- Issue #4797: IOError.filename was not set when _fileio.FileIO failed to open
2772 file with `str' filename on Windows.
2773
Antoine Pitrouaa687902009-01-01 14:11:22 +00002774- Issue #3680: Reference cycles created through a dict, set or deque iterator
2775 did not get collected.
2776
Georg Brandlba83f822010-03-14 09:50:54 +00002777- Issue #4701: PyObject_Hash now implicitly calls PyType_Ready on types where
2778 the tp_hash and tp_dict slots are both NULL.
Nick Coghlan180e4002008-12-30 01:18:48 +00002779
Benjamin Peterson7af65562008-12-29 17:56:58 +00002780- Issue #4764: With io.open, IOError.filename is set when trying to open a
2781 directory on POSIX systems.
2782
Benjamin Petersonfe231b02008-12-29 17:47:42 +00002783- Issue #4764: IOError.filename is set when trying to open a directory on POSIX
2784 systems.
2785
Georg Brandl6425a2f2008-12-28 11:54:53 +00002786- Issue #4759: None is now allowed as the first argument of
Georg Brandlba83f822010-03-14 09:50:54 +00002787 ``bytearray.translate()``. It was always allowed for ``bytes.translate()``.
Georg Brandl6425a2f2008-12-28 11:54:53 +00002788
Skip Montanarof205c132008-12-23 03:30:15 +00002789- Added test case to ensure attempts to read from a file opened for writing
2790 fail.
2791
Georg Brandlba83f822010-03-14 09:50:54 +00002792- Issue #2467: gc.DEBUG_STATS reported invalid elapsed times. Also, always print
2793 elapsed times, not only when some objects are uncollectable/unreachable.
2794 Original patch by Neil Schemenauer.
Antoine Pitrou73c0e652008-12-17 22:46:54 +00002795

Georg Brandlba83f822010-03-14 09:50:54 +00002806- Issue #4445: Replace ``sizeof(PyStringObject)`` with
2807 ``offsetof(PyStringObject, ob_sval) + 1`` when allocating memory for str
2808 instances. On a typical machine this saves 3 bytes of memory (on average) per
2809 string allocation.
Mark Dickinson826f3fe2008-12-05 21:55:28 +00002810
Amaury Forgeot d'Arcdc619012008-11-22 20:01:18 +00002811- Issue #3996: On Windows, the PyOS_CheckStack function would cause the
2812 interpreter to abort ("Fatal Python error: Could not reset the stack!")
2813 instead of throwing a MemoryError.
2814
Georg Brandlba83f822010-03-14 09:50:54 +00002815- Issue #3689: The list reversed iterator now supports __length_hint__ instead
2816 of __len__. Behavior now matches other reversed iterators.
Raymond Hettinger7989a4d2008-12-03 15:42:10 +00002817
Benjamin Petersonc078f922008-11-21 22:27:24 +00002818- Issue #4367: Python would segfault during compiling when the unicodedata
2819 module couldn't be imported and \N escapes were present.
2820
Georg Brandlba83f822010-03-14 09:50:54 +00002821- Issue #4233: Changed semantic of ``_fileio.FileIO``'s ``close()`` method on
2822 file objects with closefd=False. The file descriptor is still kept open but
2823 the file object behaves like a closed file. The ``FileIO`` object also got a
2824 new readonly attribute ``closefd``.
Amaury Forgeot d'Arc32265652008-11-20 23:34:31 +00002825
Benjamin Peterson46cc6d12008-11-19 21:49:09 +00002826- Issue #4348: Some bytearray methods returned that didn't cause any change to
2827 the bytearray, returned the same bytearray instead of a copy.
2828
Georg Brandlba83f822010-03-14 09:50:54 +00002829- Issue #4317: Fixed a crash in the ``imageop.rgb2rgb8()`` function.

2832
Benjamin Peterson6624a9f2008-11-03 15:14:51 +00002833- Issue #4048: The parser module now correctly validates relative imports.
2834
Benjamin Petersondcee09d2008-10-31 02:16:05 +00002835- Issue #4225: ``from __future__ import unicode_literals`` didn't work in an

2842 __future__ import didn't work.
2843
Benjamin Peterson399b1fe2008-10-25 02:53:28 +00002844- Using ``nonlocal`` as a variable name will now raise a Py3k SyntaxWarning
Georg Brandl7fb00ad2008-10-25 07:00:52 +00002845 because it is a reserved word in 3.x.
Benjamin Peterson399b1fe2008-10-25 02:53:28 +00002846
Georg Brandlba83f822010-03-14 09:50:54 +00002847- On windows, ``os.chdir()`` given unicode was not working if
2848 GetCurrentDirectoryW returned a path longer than MAX_PATH. (But It's doubtful
2849 this code path is really executed because I cannot move to such directory on
2850 win2k)
Hirokazu Yamamoto10a018c2008-10-09 10:00:30 +00002851
Georg Brandlba83f822010-03-14 09:50:54 +00002852- Issue #4069: When ``set.remove(element)`` is used with a set element, the
2853 element is temporarily replaced with an equivalent frozenset. But the
2854 eventual KeyError would always report the empty ``frozenset()`` as the missing
2855 key. Now it correctly refers to the initial element.

4250
Martin v. Löwis9fa5a282008-09-11 06:53:30 +00004251- Issue #3642: Suppress warning in obmalloc when size_t is larger than uint.
4252
Amaury Forgeot d'Arc05e34492008-09-10 22:04:45 +00004253- Issue #3743: In a few places, PY_FORMAT_SIZE_T was incorrectly used with
4254 PyString_FromFormat or PyErr_Format to display size_t values. The macro
4255 PY_FORMAT_SIZE_T is designed to select the correct format for the OS
4256 ``printf`` function, whereas PyString_FromFormat has an independent
4257 implementation and uses "%zd" on all platforms for size_t values.
4258 This makes a difference on win64, where ``printf`` needs "%Id" to display
4259 64bit values.
4260
Benjamin Peterson97179b02008-09-09 20:55:01 +00004261- Issue #3634: _weakref.ref(Exception).__init__() gave invalid return value on
4262 error.
4263
Amaury Forgeot d'Arcd3ffb892008-09-09 07:24:30 +00004264- Issue #3777: long() applied to a float object now always return a long
4265 object; previously an int would be returned for small values. the __long__
4266 method is allowed to return either an int or a long, but the behaviour of
4267 float objects should not change to respect backward compatibility.
4268
Amaury Forgeot d'Arc3571fbf2008-09-01 19:52:00 +00004269- Issue #3751: str.rpartition would perform a left-partition when called with
4270 a unicode argument.
4271
Benjamin Peterson17f03ca2008-09-01 14:18:30 +00004272- Issue #3683: Fix compilation when --without-threads is given.
4273
Antoine Pitroud4ae97b2008-08-29 18:39:48 +00004274- Issue #3668: Fix a memory leak with the "s*" argument parser in
Vinay Sajip35e3b032008-09-01 14:33:59 +00004275 PyArg_ParseTuple and friends, which occurred when the argument for "s*"
Antoine Pitroud4ae97b2008-08-29 18:39:48 +00004276 was correctly parsed but parsing of subsequent arguments failed.
4277
Vinay Sajip35e3b032008-09-01 14:33:59 +00004278- Issue #2534: speed up isinstance() and issubclass() by 50-70%, so as to
Antoine Pitrou0668c622008-08-26 22:42:08 +00004279 match Python 2.5 speed despite the __instancecheck__ / __subclasscheck__
4280 mechanism. In the process, fix a bug where isinstance() and issubclass(),
4281 when given a tuple of classes as second argument, were looking up
4282 __instancecheck__ / __subclasscheck__ on the tuple rather than on each
4283 type object.
4284
Neal Norwitz18aa3882008-08-24 05:04:52 +00004285- Fix crashes on memory allocation failure found with failmalloc.
4286
4287- Fix memory leaks found with valgrind and update suppressions file.
4288
4289- Fix compiler warnings in opt mode which would lead to invalid memory reads.
4290
4291- Fix problem using wrong name in decimal module reported by pychecker.
4292
Christian Heimes7d4c3172008-08-22 19:47:25 +00004293- Silenced another compiler warning about a used but not defined
4294 function 'stringlib_contains_obj'.
4295
Benjamin Peterson712ee922008-08-24 18:10:20 +00004296- Added warnings on the use of ``__getslice__``, ``__setslice__``, or
4297 ``__delslice__``.
4298
Gregory P. Smith2bb25cc2008-09-02 05:29:51 +00004299- Issue #3678: Correctly pass LDFLAGS and LDLAST to the linker on shared
4300 library targets in the Makefile.
4301
Gregory P. Smith980b99b2008-09-07 05:15:18 +00004302- Issue #1204: The configure script now tests for additional libraries
4303 that may be required when linking against readline. This fixes issues
4304 with x86_64 builds on some platforms (a few Linux flavors and OpenBSD).
4305
Benjamin Peterson14cb6bc2008-08-26 17:08:40 +00004306C-API

4313
Amaury Forgeot d'Arc24cb3822008-09-11 20:56:13 +00004314- Issue #3640: Pickling a list or a dict uses less local variables, to reduce
4315 stack usage in the case of deeply nested objects.
4316
Guido van Rossume3c4fd92008-09-10 14:27:00 +00004317- Issue #3629: Fix sre "bytecode" validator for an end case.
4318
Martin v. Löwis24329ba2008-09-10 13:38:12 +00004319- Issue #3811: The Unicode database was updated to 5.1.
4320
Nick Coghland2e09382008-09-11 12:11:06 +00004321- Issue #3781: Further warnings.catch_warnings() cleanup to prevent
4322 silent misbehaviour when a single instance is nested in multiple
4323 with statements, or when the methods are invoked in the wrong order.
4324
Vinay Sajip844f7412008-09-09 13:42:08 +00004325- Issue #3809: Fixed spurious 'test.blah' file left behind by test_logging.
4326
Nick Coghland2e09382008-09-11 12:11:06 +00004327- Issue #3781: Clean up the API for warnings.catch_warnings() by having it
Brett Cannon672237d2008-09-09 00:49:16 +00004328 return a list or None rather than a custom object.
4329
Benjamin Peterson6ac7d7c2008-09-06 19:28:11 +00004330- Issue #1638033: Cookie.Morsel gained the httponly attribute.
4331
Antoine Pitrouebcd0ce2008-09-05 23:30:23 +00004332- Issue #3535: zipfile couldn't read some zip files larger than 2GB.
4333
4334- Issue #3776: Deprecate the bsddb package for removal in 3.0.
Brett Cannon32476fc2008-09-05 18:33:51 +00004335
Hirokazu Yamamoto42e459e2008-09-04 14:25:30 +00004336- Issue #3762: platform.architecture() fails if python is lanched via
4337 its symbolic link.
4338
Vinay Sajip65d66e12008-09-04 07:31:21 +00004339- Issue #3772: Fixed regression problem in StreamHandler.emit().

Facundo Batistac585df92008-09-03 22:35:50 +00004342 to the urlparse one. Added a PendingDeprecationWarning in the old
4343 module, it will be deprecated in the future.
4344
Marc-André Lemburgb339b2a2008-09-03 11:13:56 +00004345- Issue #2562: Fix distutils PKG-INFO writing logic to allow having

4351 path to the Python binary.
4352
Georg Brandl222e2082010-08-01 22:27:39 +00004353- Issue #3602: Moved test.test_support.catch_warning() to
Brett Cannon1eaf0742008-09-02 01:25:16 +00004354 warnings.catch_warnings() along with some API cleanup. Expanding the tests
4355 for catch_warnings() also led to an improvement in the raising of a
4356 DeprecationWarning related to warnings.warn_explicit().
4357
Benjamin Peterson973e6c22008-09-01 23:12:58 +00004358- The deprecation warnings for the old camelCase threading API were removed.
4359
Vinay Sajip35e3b032008-09-01 14:33:59 +00004360- logging: fixed lack of use of encoding attribute specified on a stream.
4361
Christian Heimesa27a62e2008-08-22 19:55:54 +00004362- Silenced a trivial compiler warning in the sqlite module.
4363
Christian Heimes1cc69632008-08-22 20:10:27 +00004364- Fixed two format strings in the _collections module.
4365
Benjamin Peterson17f03ca2008-09-01 14:18:30 +00004366- Issue #3703: _fileio.FileIO gave unhelpful error message when trying to open a
4367 directory.
Benjamin Petersonf22c26e2008-09-01 14:13:43 +00004368
Gregory P. Smithd7122032008-09-02 05:36:11 +00004369- Issue #3708: os.urandom no longer goes into an infinite loop when passed a
4370 non-integer floating point number.
4371
Vinay Sajip65d66e12008-09-04 07:31:21 +00004372- Issue #3110: multiprocessing fails to compiel on solaris 10 due to missing

4377
Jesse Noller438195f2009-01-18 21:04:36 +00004378- Issue #4301: Patch the logging module to add processName support, remove
4379 _check_logger_class from multiprocessing.
4380
Amaury Forgeot d'Arc293924b2008-09-02 23:19:56 +00004381- Issue #2975: When compiling several extension modules with Visual Studio 2008
4382 from the same python interpreter, some environment variables would grow
4383 without limit.
4384
Benjamin Peterson37346b22008-08-23 20:27:43 +00004385- Issue #3643: Added a few more checks to _testcapi to prevent segfaults by
4386 exploitation of poor argument checking.
4387
Gerhard Häringef2276b2008-09-12 13:54:06 +00004388- sqlite3: Changed docstring of iterdump() to mark method as "Non-standard".
4389
Gerhard Häring6e1afcf2008-09-12 18:58:57 +00004390- Issue #3103: Reduced globals symbols used by sqlite3 module and made sure all
4391 remaining ones have "pysqlite_" prefix.
4392
Gerhard Häringe6872eb2008-09-12 22:33:22 +00004393- Issue #3846: Release the GIL during sqlite3_prepare calls. This improves

4399
Nick Coghland2e09382008-09-11 12:11:06 +00004400- Issue #3781: Add test.test_support.check_warnings() as a convenience
4401 wrapper for warnings.catch_warnings() that makes it easier to check
4402 that expected warning messages are being reported.
4403
Amaury Forgeot d'Arcfeb8cad2008-09-06 20:53:51 +00004404- Issue #3796: Some tests functions were not enabled in test_float.
4405
4406- Issue #3768: Move test_py3kwarn over to the new API for catch_warnings().

Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00004422What's New in Python 2.6 beta 3?
4423================================
4424
Barry Warsaw07a4a382008-08-21 01:15:08 +00004425*Release date: 20-Aug-2008*
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00004426
4427Core and Builtins
4428-----------------
4429
Guido van Rossumf8402962008-08-20 15:01:50 +00004430- Issue #1878: Remove Py_TPFLAGS_HAVE_VERSION_TAG from
4431 Py_TPFLAGS_DEFAULT when not building the core. This means 3rd party
4432 extensions do not automatically benefit from the class attribute
4433 cache; they will have to explicitly add Py_TPFLAGS_HAVE_VERSION_TAG
4434 to their tp_flags field if they care. This is a backwards
4435 compatibility feature; in 3.0, all types will use the cache by
4436 default.
4437
Benjamin Petersonf647dc12008-08-20 01:27:30 +00004438- Keyword arguments can now follow starred arguments. (``f(a, *args,
4439 keyword=23)`` is now valid syntax.)
4440
Thomas Heller0ad5ae02008-08-19 19:25:04 +00004441- ctypes function pointers that are COM methods have a boolean True
4442 value again.
4443
Martin v. Löwisf91d46a2008-08-12 14:49:50 +00004444- Issue #3139: Make buffer-interface thread-safe wrt. PyArg_ParseTuple,
4445 by denying s# to parse objects that have a releasebuffer procedure,
4446 and introducing s*.
4447
Georg Brandl1e13ea92008-08-11 09:07:59 +00004448- Issue #3537: Fix an assertion failure when an empty but presized dict
4449 object was stored in the freelist.
4450
Mark Dickinsonb6467572008-08-04 21:30:09 +00004451- Issue #1481296: Make long(float('nan')) and int(float('nan')) raise
4452 ValueError consistently across platforms.
4453
Amaury Forgeot d'Arc39fd6722008-07-31 21:28:03 +00004454- Issue #3479: On platforms where sizeof(int) is smaller than sizeof(long)
4455 (64bit Unix, for example), unichr() would truncate its argument and return
4456 u'\x00' for unichr(2**32). Now it properly raises an OverflowError.
4457
Neal Norwitze7d8be82008-07-31 17:17:14 +00004458- Apply security patches from Apple.
4459
Amaury Forgeot d'Arc246daed2008-07-31 00:42:16 +00004460- Issue #2542: Now that issubclass() may call arbitrary code, ensure that
4461 PyErr_ExceptionMatches returns 0 when an exception occurs there.
4462
Antoine Pitrou92f82162008-07-25 22:22:08 +00004463- Issue #1819: function calls with several named parameters are now on
4464 average 35% faster (as measured by pybench).
4465
Amaury Forgeot d'Arce4921fe2008-07-21 22:00:38 +00004466- Issue #2378: An unexpected UnboundLocalError or NameError could appear when
4467 the python debugger steps into a class statement: the free variables (local
4468 variables defined in an outer scope) would be deleted from the outer scope.
4469
Gregory P. Smith0470bab2008-07-22 04:46:32 +00004470- Issue #2620: Overflow checking when allocating or reallocating memory
4471 was not always being done properly in some python types and extension
4472 modules. PyMem_MALLOC, PyMem_REALLOC, PyMem_NEW and PyMem_RESIZE have
4473 all been updated to perform better checks and places in the code that
4474 would previously leak memory on the error path when such an allocation
4475 failed have been fixed.

4478-------
4479
Hirokazu Yamamoto838c79f2008-08-20 13:14:07 +00004480- Issue #3612: Added some missing basic types in ctypes.wintypes.
4481
Benjamin Petersone977ad42008-08-20 01:42:01 +00004482- The methods ``is_in_tuple()``, ``is_vararg()``, and ``is_keywordarg()`` of
4483 symtable.Symbol have been deprecated for removal in 3.0 and the next release.
4484
Amaury Forgeot d'Arc351ffb82008-08-18 19:23:47 +00004485- Issue #2234: distutils failed for some versions of the cygwin compiler. The
4486 version reported by these tools does not necessarily follow the python
4487 version numbering scheme, so the module is less strict when parsing it.
4488
Nick Coghlanf70385a2008-08-18 12:42:46 +00004489- Issue #2235: Added Py3k warnings for types which will become unhashable
4490 under the stricter __hash__ inheritance rules in 3.0. Several types
4491 which did not meet the rules for hash invariants and were already
4492 unhashable in 3.0 have now been explicitly flagged as unhashable in
4493 2.6 as well (collections.Mapping, collections.Set, unittest.TestSuite,
4494 xml.dom.minidom.NamedNodeMap, numbers.Number, UserList.UserList)
4495
Brett Cannon88f801d2008-08-18 00:46:22 +00004496- Update __all__ for cookielib, csv, os, urllib2, and weakref to include things
4497 imported into the module but exposed as part of the module's API.
4498
Brett Cannon7b96f072008-08-18 00:41:11 +00004499- Remove an unneeded import of abc.ABCMeta from 'inspect'.

Brett Cannon25c9d6a2008-08-17 22:10:11 +00004503- Remove unneeded imports of 'warnings' from shelve, filecmp, and dummy_thread.
4504
Hirokazu Yamamoto41a81eb2008-08-17 13:10:46 +00004505- Issue #3575: Incremental decoder's decode function now takes bytearray
4506 by using 's*' instead of 't#'.
4507
Mark Dickinson3e4caeb2009-02-21 20:27:01 +00004508- Issue #2222: Fixed reference leak when occurred os.rename()
Hirokazu Yamamoto7f30a682008-08-17 09:46:56 +00004509 fails unicode conversion on 2nd parameter. (windows only)
4510
Georg Brandl222e2082010-08-01 22:27:39 +00004511- Issue #2464: urllib2 now supports a malformation in the URL received
Facundo Batista94f243a2008-08-17 03:38:39 +00004512 in a redirect.
4513
Brett Cannonabe423e2008-08-16 21:47:07 +00004514- Silence the DeprecationWarning raised when importing mimetools in
Brett Cannon721b1452008-08-16 22:00:27 +00004515 BaseHTTPServer, cgi (and rfc822), httplib.
Brett Cannonabe423e2008-08-16 21:47:07 +00004516
Facundo Batistaeb90b782008-08-16 14:44:07 +00004517- Issue #2776: fixed small issue when handling an URL with double slash
4518 after a 302 response in the case of not going through a proxy.
4519
Antoine Pitroub90a8be2008-08-15 21:03:21 +00004520- Issue #2676: in the email package, content-type parsing was hanging on
4521 pathological input because of quadratic or exponential behaviour of a
4522 regular expression.
4523
Antoine Pitrou11ec65d2008-08-14 21:04:30 +00004524- Issue #3476: binary buffered reading through the new "io" library is now
4525 thread-safe.
4526
Brett Cannonbf3157b2008-08-14 05:00:03 +00004527- Silence the DeprecationWarning of rfc822 when it is imported by mimetools
4528 since mimetools itself is deprecated. Because modules are cached, all
4529 subsequent imports of rfc822 will not raise a visible DeprecationWarning.
4530
Antoine Pitrou9fcd4b32008-08-11 17:21:36 +00004531- Issue #3134: shutil referenced undefined WindowsError symbol.
4532
Robert Schuppenies14646332008-08-10 11:01:53 +00004533- Issue #1342811: Fix leak in Tkinter.Menu.delete. Commands associated to
4534 menu entries were not deleted.

Antoine Pitroude781a42008-08-09 12:43:23 +00004565 asking for a specific length. This problem only affected files opened

4609
Nick Coghlan2a0c2b12008-08-04 12:47:17 +00004610- Issue #643841: The language reference now provides more detailed
4611 coverage of the lookup process for special methods. The disclaimers
4612 regarding lack of coverage of new-style classes have also been

4622-----------------
4623
Georg Brandl3e483f62008-07-16 22:57:41 +00004624- Issue #3156: Fix inconsistent behavior of the bytearray type: all
4625 its methods now allow for items objects that can be converted to
4626 an integer using operator.index().
4627
Mark Dickinson64b7e502008-07-16 09:40:03 +00004628- Issue #3360: Fix incorrect parsing of '020000000000.0', which
4629 produced a ValueError instead of giving the correct float.
4630
Eric Smitha5fa5a22008-07-16 00:11:49 +00004631- Issue #3083: Add alternate (#) formatting for bin, oct, hex output
4632 for str.format(). This adds the prefix 0b, 0o, or 0x, respectively.
4633
Mark Dickinson7103aa42008-07-15 19:08:33 +00004634- Issue #3008: the float type has a new instance method 'float.hex'
4635 and a new class method 'float.fromhex' to convert floating-point
4636 numbers to and from hexadecimal strings, respectively.
4637
Nick Coghlan6d6bd442008-07-15 15:40:22 +00004638- Issue #2235: __hash__ is once again inherited by default. To allow
4639 collections.Hashable to remain meaningful in the presence of the
4640 default hash implementation (object.__hash__), it is now possible
4641 to explicit block inheritance of hash by setting __hash__=None at
4642 the Python level, or tp_hash=PyObject_HashNotImplemented at the C
4643 level.
4644
Nick Coghlanb028f502008-07-13 14:52:36 +00004645- Issue #3221: Issue a RuntimeWarning instead of raising SystemError if
4646 the parent module cannot be found while performing an absolute import.
4647 This means that an incorrectly defined __package__ attribute will
4648 now only prevent relative imports in that module rather than causing
4649 all imports from that module to fail.
4650
Nick Coghlan14ff9942008-07-08 14:21:42 +00004651- Issue #2517: Allow unicode messages in Exceptions again by correctly

4661 another thread's dictionary.
4662
Mark Dickinson1ec2fcd2008-06-20 14:53:43 +00004663- Issue #3004: Minor change to slice.indices(): the start and stop
4664 arguments are now treated identically, making the behaviour easier
4665 to describe and understand. For example, slice(None, -10,
4666 1).indices(9) now returns (0, 0, 1) instead of (0, -1, 1), and
4667 slice(None, 10, -1).indices(10) returns (9, 9, -1) instead of (9,
4668 10, -1).
4669
Georg Brandl278fc502008-07-19 12:46:12 +00004670- Issue #3219: Calling a function with repeated keyword arguments,
4671 f(a=2, a=23), would not cause a syntax error. This was a regression
4672 from 2.4 caused by the switch to the new compiler.

Amaury Forgeot d'Arc0f7cddc2008-07-06 21:34:39 +00004710- Issue #839496: SimpleHTTPServer used to open text files in text mode. This is
4711 both unnecessary (HTTP allows text content to be sent in several forms) and
Andrew M. Kuchlingcc3f2b12008-07-10 14:43:31 +00004712 wrong because the actual transmitted size could differ from the
Amaury Forgeot d'Arc0f7cddc2008-07-06 21:34:39 +00004713 content-length. The problem had been corrected in the 2.4 branch, but never

Nick Coghlanc060b0e2008-07-02 13:09:19 +00004729- Issue #3190: Pydoc now hides the automatic module attribute __package__ (the

5102 an extension. This was added for compatibility with Apple's build
5103 of Python.
5104
5105- The bundled OSX-specific copy of libbffi is now in sync with the version
5106 shipped with PyObjC 2.0 and includes support for x86_64 and ppc64 platforms.
5107
Georg Brandl25c34082008-08-18 23:09:49 +00005108- The threading module gained aliases for names that will be removed in the
5109 3.x series.

5117
Brett Cannonb61d8012008-05-11 23:39:04 +00005118- ``Lib/lib-old`` is now added to sys.path.
5119
Ronald Oussoren5640ce22008-06-05 12:58:24 +00005120- On MacOS X it is now possible to install the framework in 64-bit
5121 mode or even as a 4-way universal binary (that is, PPC, i386,
Georg Brandl5cc774e2008-06-11 20:28:06 +00005122 PPC64 and x86_64 support in one binary).
Ronald Oussoren5640ce22008-06-05 12:58:24 +00005123
5124 This is controlled by the configure argument ``--with-universal-archs``:
5125
5126 - ``--with-universal-archs=all``: install 4-way universal
5127
5128 - ``--with-universal-archs=32-bit``: install 2-way universal, 32-bit (the default)
5129
5130 - ``--with-universal-archs=64-bit``: install 2-way universal, 64-bit
5131
5132 This option should be used in combination with ``--enable-universalsdk=``.
5133
5134 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 +00005143
5144- The PyString functions have been renamed to PyBytes. A batch of
5145 defines were added so that the linker still sees the original
5146 PyString names.

Georg Brandl3ee81df2008-05-17 18:14:43 +00005184- Issue #1631171: Re-implement the 'warnings' module in C (the
5185 original Python code has been kept as backup). This will allow for
5186 using the 'warning's machinery in such places as the parser where
5187 use of pure Python code is not possible. Both the ``showarning()``
5188 and ``formatwarning()`` gain an optional 'line' argument which is
5189 not called by default for backwards-compatibility reasons. Setting
5190 ``warnings.showwarning()`` to an implementation that lacks support
5191 for the ``line`` argument will raise a DeprecationWarning.

Gregory P. Smithd59fefb2008-04-22 08:11:33 +00005216- The getpass module has been improved on Unix. It now uses /dev/tty
5217 by default and uses stderr instead of stdout. A GetPassWarning is
5218 issued when input echo cannot be controlled.

Georg Brandl3ee81df2008-05-17 18:14:43 +00005233- Issue #2513: distutils on Windows is now capable of cross-compiling
Mark Hammond495cf992008-04-07 01:53:39 +00005234 extension modules between 32 and 64 bit platforms. See the distutls

Georg Brandl3ee81df2008-05-17 18:14:43 +00005254- Issue #2550: The approach used by client/server code for obtaining
5255 ports to listen on in network-oriented tests has been refined in an
5256 effort to facilitate running multiple instances of the entire
5257 regression test suite in parallel without issue.
5258 test_support.bind_port() has been fixed such that it will always
5259 return a unique port -- which wasn't always the case with the
5260 previous implementation, especially if socket options had been set
5261 that affected address reuse (i.e. SO_REUSEADDR, SO_REUSEPORT). The
5262 new implementation of bind_port() will actually raise an exception
5263 if it is passed an AF_INET/SOCK_STREAM socket with either the
5264 SO_REUSEADDR or SO_REUSEPORT socket option set. Furthermore, if
5265 available, bind_port() will set the SO_EXCLUSIVEADDRUSE option on
5266 the socket it's been passed. This currently only applies to
5267 Windows. This option prevents any other sockets from binding to the
5268 host/port we've bound to, thus removing the possibility of the
5269 'non-deterministic' behaviour, as Microsoft puts it, that occurs
5270 when a second SOCK_STREAM socket binds and accepts to a host/port
5271 that's already been bound by another socket. The optional preferred
5272 port parameter to bind_port() has been removed. Under no
5273 circumstances should tests be hard coding ports!
5274
5275 test_support.find_unused_port() has also been introduced, which will
5276 pass a temporary socket object to bind_port() in order to obtain an
5277 unused port. The temporary socket object is then closed and
5278 deleted, and the port is returned. This method should only be used
5279 for obtaining an unused port in order to pass to an external program
5280 (i.e. the -accept [port] argument to openssl's s_server mode) or as
5281 a parameter to a server-oriented class that doesn't give you direct
5282 access to the underlying socket used.
5283
5284 Finally, test_support.HOST has been introduced, which should be used
5285 for the host argument of any relevant socket calls (i.e. bind and
5286 connect).
Trent Nelsone41b0062008-04-08 23:47:30 +00005287
5288 The following tests were updated to following the new conventions:
Georg Brandl3ee81df2008-05-17 18:14:43 +00005289 test_socket, test_smtplib, test_asyncore, test_ssl, test_httplib,
Trent Nelsone41b0062008-04-08 23:47:30 +00005290 test_poplib, test_ftplib, test_telnetlib, test_socketserver,
5291 test_asynchat and test_socket_ssl.
5292
Georg Brandl3ee81df2008-05-17 18:14:43 +00005293 It is now possible for multiple instances of the regression test
5294 suite to run in parallel without issue.

Eric Smitha73fbe72008-02-23 03:09:44 +00005573- Added the future_builtins module, which contains hex() and oct().
5574 These are the PEP 3127 version of these functions, designed to be
5575 compatible with the hex() and oct() builtins from Python 3.0. They
5576 differ slightly in their output formats from the existing, unchanged
5577 Python 2.6 builtins. The expected usage of the future_builtins
5578 module is:
5579 from future_builtins import hex, oct
5580
Eric Smith7ef40bf2008-02-20 23:34:22 +00005581- Issue #1600: Modifed PyOS_ascii_formatd to use at most 2 digit
5582 exponents for exponents with absolute value < 100. Follows C99
5583 standard. This is a change on Windows, which would use 3 digits.
5584 Also, added 'n' to the formats that PyOS_ascii_formatd understands,
5585 so that any alterations it does to the resulting string will be
5586 available in stringlib/formatter.h (for float.__format__).
5587
Eric Smith5a3c1352008-02-19 13:21:56 +00005588- Implemented PEP 3101, Advanced String Formatting. This adds a new
5589 builtin format(); a format() method for str and unicode; a
5590 __format__() method to object, str, unicode, int, long, float, and
5591 datetime; the class string.Formatter; and the C API
5592 PyObject_Format().
5593
Georg Brandl3ee81df2008-05-17 18:14:43 +00005594- Fixed several potential crashes, all caused by specially crafted
5595 __del__ methods exploiting objects in temporarily inconsistent
5596 state.

5606 in order to allow pymalloc to free more arenas. Python may give back
5607 memory to the OS earlier.
Christian Heimes3b718a72008-02-14 12:47:33 +00005608
Georg Brandl3ee81df2008-05-17 18:14:43 +00005609- Issue #2045: Fix an infinite recursion triggered when printing a
5610 subclass of collections.defaultdict, if its default_factory is set
5611 to a bound method.
Amaury Forgeot d'Arcb01aa432008-02-08 00:56:02 +00005612
Christian Heimesf75dbef2008-02-08 00:11:31 +00005613- Fixed a minor memory leak in dictobject.c. The content of the free
5614 list was not freed on interpreter shutdown.
5615
Georg Brandl21e99f42010-03-07 15:23:59 +00005616- Limit free list of method and built-in function objects to 256

Christian Heimes6075a822008-02-06 12:44:34 +00005618
Georg Brandl3ee81df2008-05-17 18:14:43 +00005619- Patch #1953: Added ``sys._compact_freelists()`` and the C API
5620 functions ``PyInt_CompactFreeList`` and ``PyFloat_CompactFreeList``
Christian Heimes422051a2008-02-04 18:00:12 +00005621 to compact the internal free lists of pre-allocted ints and floats.
5622
Georg Brandl3ee81df2008-05-17 18:14:43 +00005623- Issue #1983: Fixed return type of fork(), fork1() and forkpty()
5624 calls. Python expected the return type int but the fork familie
5625 returns pi_t.
Christian Heimes951cc0f2008-01-31 23:08:23 +00005626
Georg Brandl3ee81df2008-05-17 18:14:43 +00005627- Issue #1678380: Fix a bug that identifies 0j and -0j when they
5628 appear in the same code unit.
Mark Dickinson105be772008-01-31 22:17:37 +00005629
Georg Brandl3ee81df2008-05-17 18:14:43 +00005630- Issue #2025: Add tuple.count() and tuple.index() methods to comply
5631 with the collections.Sequence API.
Raymond Hettinger5b07ebc2008-02-07 00:54:20 +00005632
Georg Brandl3ee81df2008-05-17 18:14:43 +00005633- Patch #1970 by Antoine Pitrou: Speedup unicode whitespace and
5634 linebreak detection

Georg Brandl3ee81df2008-05-17 18:14:43 +00005636- Added ``PyType_ClearCache()`` and ``sys._clear_type_cache`` to clear
5637 the internal lookup cache for ref leak tests.
Christian Heimes908caac2008-01-27 23:34:59 +00005638
Georg Brandl3ee81df2008-05-17 18:14:43 +00005639- Patch #1473257: generator objects gain a gi_code attribute. This is
5640 the same object as the func_code attribute of the function that
5641 produced the generator.
Georg Brandl0cdf9a32008-01-26 14:14:20 +00005642
Georg Brandl3ee81df2008-05-17 18:14:43 +00005643- Issue #1920: "while 0" statements were completely removed by the
5644 compiler, even in the presence of an "else" clause, which is
5645 supposed to be run when the condition is false. Now the compiler
5646 correctly emits bytecode for the "else" suite.
Amaury Forgeot d'Arc31eaafe2008-01-24 22:59:25 +00005647
Guido van Rossumeead05f2008-01-24 18:21:02 +00005648- A few crashers fixed: weakref_in_del.py (issue #1377858);
5649 loosing_dict_ref.py (issue #1303614, test67.py);
5650 borrowed_ref_[34].py (not in tracker).
5651
Vinay Sajipd7cf32e2008-01-24 12:43:33 +00005652- Issue #1069410: The "can't load dll" message box on Windows is
Christian Heimesb2302ba2008-01-23 17:15:06 +00005653 suppressed while an extension is loaded by calling SetErrorMode in
5654 dynload_win.c. The error is still reported properly.
5655
Georg Brandl3ee81df2008-05-17 18:14:43 +00005656- Issue #1915: Python compiles with --enable-unicode=no again. However
Christian Heimes082c9b02008-01-23 14:20:50 +00005657 several extension methods and modules do not work without unicode
5658 support.
5659
Georg Brandl26543b12008-01-21 18:36:51 +00005660- Issue #1882: when compiling code from a string, encoding cookies in the
5661 second line of code were not always recognized correctly.
5662
Georg Brandl14404b62008-01-19 19:27:05 +00005663- Issue #1679: "0x" was taken as a valid integer literal.
5664
Georg Brandl6caad7d2008-01-26 14:19:22 +00005665- Issue #1865: ``bytes`` as an alias for ``str`` and b"" as an alias "" were
Christian Heimes288e89a2008-01-18 18:24:07 +00005666 added.
5667
Christian Heimesc94e2b52008-01-14 04:13:37 +00005668- sys.float_info / PyFloat_GetInfo: The floating point information
5669 object was converted from a dict to a specialized structseq object.
5670
Georg Brandl3ee81df2008-05-17 18:14:43 +00005671- Patch #1816: Added sys.flags structseq. It exposes the status of
5672 most command line arguments and PYTHON* environment variables.
Christian Heimesf31b69f2008-01-14 03:42:48 +00005673
Georg Brandl3ee81df2008-05-17 18:14:43 +00005674- Objects/structseq.c: Implemented new structseq representation. The
5675 patch makes structseqs (e.g. the return value of os.stat) more
5676 readable.
Christian Heimes9c201962008-01-14 03:33:52 +00005677
Georg Brandl3ee81df2008-05-17 18:14:43 +00005678- Patch #1700288: added a type attribute cache that caches method
5679 accesses, resulting in speedups in heavily object-oriented code.
Amaury Forgeot d'Arce4c270c2008-01-14 00:29:41 +00005680
Neal Norwitz3fc15b82008-01-10 05:42:58 +00005681- Bug #1776: __import__() no longer accepts filenames on any platform.
5682 The first parameter to __import__() must be a valid module name.
Christian Heimes3403f152008-01-09 19:56:33 +00005683
Georg Brandlaed6c662008-01-07 17:25:53 +00005684- Patch #1668: renamed THREADDEBUG envvar to PYTHONTHREADDEBUG.
5685
Georg Brandl3ee81df2008-05-17 18:14:43 +00005686- Patch #602345: Add -B command line option, PYTHONDONTWRITEBYTECODE
5687 envvar and sys.dont_write_bytecode attribute. All these can be set
5688 to forbid Python to attempt to write compiled bytecode files.
Georg Brandl2da0fce2008-01-07 17:09:35 +00005689
Georg Brandl3ee81df2008-05-17 18:14:43 +00005690- Improve some exception messages when Windows fails to load an
5691 extension module. Now we get for example '%1 is not a valid Win32
5692 application' instead of 'error code 193'.
Amaury Forgeot d'Arce0b76952008-01-04 02:04:15 +00005693

Georg Brandl3ee81df2008-05-17 18:14:43 +00005696- Issue #1640: Added math.isinf(x), math.isnan(x) and math.copysign(x,
5697 y) functions.
Christian Heimese2ca4242008-01-03 20:23:15 +00005698
Christian Heimes0a8143f2007-12-18 23:22:54 +00005699- Issue #1635: Platform independent creation and representation of NaN
Georg Brandl3ee81df2008-05-17 18:14:43 +00005700 and INF. float("nan"), float("inf") and float("-inf") now work on
5701 every platform with IEEE 754 semantics.
Christian Heimes0a8143f2007-12-18 23:22:54 +00005702
Georg Brandl3ee81df2008-05-17 18:14:43 +00005703- Compiler now generates simpler and faster code for dictionary
5704 literals. The oparg for BUILD_MAP now indicates an estimated
5705 dictionary size. There is a new opcode, STORE_MAP, for adding
5706 entries to the dictionary.

Georg Brandl3ee81df2008-05-17 18:14:43 +00005735- Patch #1739468: Directories and zipfiles containing a __main__.py
5736 file can now be directly executed by passing their name to the
5737 interpreter. The directory/zipfile is automatically inserted as the
5738 first entry in sys.path.
Nick Coghlan327a39b2007-11-18 11:56:28 +00005739
Georg Brandl3ee81df2008-05-17 18:14:43 +00005740- Issue #1265: Fix a problem with sys.settrace, if the tracing
5741 function uses a generator expression when at the same time the
5742 executed code is closing a paused generator.
Amaury Forgeot d'Arc0d75f092007-11-13 21:54:28 +00005743
Raymond Hettinger1760c8a2007-11-08 02:52:43 +00005744- sets and frozensets now have an isdisjoint() method.
5745
Raymond Hettinger3f8caa32007-10-24 01:28:33 +00005746- optimize the performance of builtin.sum().
5747
Neal Norwitz44f326e2007-10-05 05:29:17 +00005748- Fix warnings found by the new version of the Coverity checker.
5749
Georg Brandl21e99f42010-03-07 15:23:59 +00005750- The enumerate() built-in function is no longer bounded to sequences
Georg Brandl3ee81df2008-05-17 18:14:43 +00005751 smaller than LONG_MAX. Formerly, it raised an OverflowError. Now,
5752 automatically shifts from ints to longs.
Raymond Hettinger8f669372007-10-03 21:18:11 +00005753
Georg Brandl3ee81df2008-05-17 18:14:43 +00005754- Issue #1686386: Tuple's tp_repr did not take into account the
5755 possibility of having a self-referential tuple, which is possible
5756 from C code. Nor did object's tp_str consider that a type's tp_str
5757 could do something that could lead to an inifinite recursion.
5758 Py_ReprEnter() and Py_EnterRecursiveCall(), respectively, fixed the
5759 issues.
Brett Cannon0b14f242007-09-30 19:45:10 +00005760
Georg Brandl3ee81df2008-05-17 18:14:43 +00005761- Issue #1164: It was possible to trigger deadlock when using the
5762 'print' statement to write to a file since the GIL was not released
5763 as needed. Now PyObject_Print() does the right thing along with
5764 various tp_print implementations of the built-in types and those in
5765 the collections module.
Brett Cannon01531592007-09-17 03:28:34 +00005766
Georg Brandl3ee81df2008-05-17 18:14:43 +00005767- Issue #1147: Exceptions were directly allowing string exceptions in
5768 their throw() method even though string exceptions no longer
5769 allowed.
Brett Cannon4c20bc42007-09-11 21:02:28 +00005770
Georg Brandl3ee81df2008-05-17 18:14:43 +00005771- Issue #1096: Prevent a segfault from getting the repr of a very
5772 deeply nested list by using the recursion counter.
Brett Cannona0c05512007-09-10 21:38:27 +00005773
Brett Cannon1e534b52007-09-07 04:18:30 +00005774- Issue #1202533: Fix infinite recursion calls triggered by calls to
Georg Brandl3ee81df2008-05-17 18:14:43 +00005775 PyObject_Call() never calling back out to Python code to trigger
5776 recursion depth updates/checks. Required the creation of a static
5777 RuntimeError instance in case normalizing an exception put the
5778 recursion check value past its limit. Fixes crashers
5779 infinite_rec_(1|2|4|5).py.
Brett Cannon1e534b52007-09-07 04:18:30 +00005780

Neal Norwitz0ac60192007-05-27 04:08:54 +00005794- Add new attribute names for function objects. All the func_* become
Georg Brandl3ee81df2008-05-17 18:14:43 +00005795 __*__ attributes. (Some already existed, e.g., __doc__ and
5796 __name__.)
Neal Norwitz0ac60192007-05-27 04:08:54 +00005797
Neal Norwitz8b2bfbc2007-05-23 06:35:32 +00005798- Add -3 option to the interpreter to warn about features that are
5799 deprecated and will be changed/removed in Python 3.0.
5800
Georg Brandl2134e752007-05-21 20:34:16 +00005801- Patch #1686487: you can now pass any mapping after '**' in function
5802 calls.
5803
Collin Winter62903052007-05-18 23:11:24 +00005804- except clauses may now be spelled either "except E, target:" or
Georg Brandl3ee81df2008-05-17 18:14:43 +00005805 "except E as target:". This is to provide forwards compatibility
5806 with Python 3.0.

Brett Cannon229cee22007-05-05 01:34:02 +00005808- Deprecate BaseException.message as per PEP 352.
5809
Georg Brandl3ee81df2008-05-17 18:14:43 +00005810- Issue #1303614: don't expose object's __dict__ when the dict is
Georg Brandl21e99f42010-03-07 15:23:59 +00005811 inherited from a built-in base.
Armin Rigo9790a272007-05-02 19:23:31 +00005812
Vinay Sajip8549ce32007-05-06 17:53:37 +00005813- When __slots__ are set to a unicode string, make it work the same as
Neal Norwitzcbd9ee62007-04-14 05:25:50 +00005814 setting a plain string, ie don't expand to single letter identifiers.
5815
Raymond Hettinger13936692007-04-11 18:40:58 +00005816- Request #1191699: Slices can now be pickled.
5817
Raymond Hettinger4db5fe92007-04-12 04:10:00 +00005818- Request #1193128: str.translate() now allows a None argument for
5819 translations that only remove characters without re-mapping the
5820 remaining characters.
5821
Georg Brandl5cb76c12007-03-21 09:00:39 +00005822- Patch #1682205: a TypeError while unpacking an iterable is no longer
5823 masked by a generic one with the message "unpack non-sequence".
5824
Neal Norwitzaa754b72007-03-21 06:39:48 +00005825- Remove unused file Python/fmod.c.
5826
Guido van Rossum143b5642007-03-23 04:58:42 +00005827- Bug #1683368: The object.__init__() and object.__new__() methods are
5828 now stricter in rejecting excess arguments. The only time when
5829 either allows excess arguments is when it is not overridden and the
5830 other one is. For backwards compatibility, when both are
5831 overridden, it is a deprecation warning (for now; maybe a Py3k
Guido van Rossum234b1ff2007-03-23 19:39:01 +00005832 warning later). Also, type.__init__() insists on the same signature
5833 as supported by type.__new__().

Georg Brandl3ee81df2008-05-17 18:14:43 +00005835- Patch #1675423: PyComplex_AsCComplex() now tries to convert an
5836 object to complex using its __complex__() method before falling back
5837 to the __float__() method. Therefore, the functions in the cmath
5838 module now can operate on objects that define a __complex__()
5839 method.

Georg Brandl871f1bc2007-03-12 13:17:36 +00005860- The dir() function has been extended to call the __dir__() method on
Georg Brandl3ee81df2008-05-17 18:14:43 +00005861 its argument, if it exists. If not, it will work like before. This
5862 allows customizing the output of dir() in the presence of a

Georg Brandl3ee81df2008-05-17 18:14:43 +00006387 the client's request was successfully received, understood, and

6520 TestCase and TestSuite subclasses (not instances) are no longer

Georg Brandl3ee81df2008-05-17 18:14:43 +00006913 time so that opening a database previously created with the DB_DUP
6914 or DB_DUPSORT flag set will keep the proper behavior on subsequent
6915 opens. Specifically: dictionary assignment to a DB object will
6916 replace all values for a given key when the database allows
6917 duplicate values. DB users should use DB.put(k, v) when they want
6918 to store duplicates; not DB[k] = v.

6925 characters with ASCII value less than 32. Also, it correctly quotes
6926 dots only if they occur on a single line, as opposed to the previous
6927 behavior of quoting dots if they are the second character of any
6928 line.
