281 (2**53+1 == complex(2**53) == 2**53), breaking transivity of equality.

Mark Dickinsond2f3e3f2010-05-05 22:23:58 +0000626 (Optimization was unintentionally turned on in gcc --with-pydebug builds in

649-----------------
650
Philip Jenveyaebbaeb2010-04-06 23:24:45 +0000651- Issue #7301: Add environment variable $PYTHONWARNINGS.
652
Benjamin Peterson3a1dfa22010-04-06 21:50:00 +0000653- Issue #8329: Don't return the same lists from select.select when no fds are
654 changed.
655
Georg Brandlfee0f442010-05-22 21:26:21 +0000656- Issue #8259: ``1L << (2**31)`` no longer produces an 'outrageous shift error'
Mark Dickinson82791672010-04-06 16:47:55 +0000657 on 64-bit machines. The shift count for either left or right shift is
658 permitted to be up to sys.maxsize.
659
Benjamin Peterson4ceeeb02010-04-03 22:48:51 +0000660- Ensure that tokenization of identifiers is not affected by locale.

Benjamin Peterson1c7c11e2010-04-03 01:28:57 +0000664- Raise a TypeError when trying to delete a T_STRING_INPLACE struct member.
665
Georg Brandlfee0f442010-05-22 21:26:21 +0000666- Issue #7994: Issue a PendingDeprecationWarning if object.__format__ is called
667 with a non-empty format string. This is an effort to future-proof user
668 code. If a derived class does not currently implement __format__ but later
669 adds its own __format__, it would most likely break user code that had
670 supplied a format string. This will be changed to a DeprecationWaring in
671 Python 3.3 and it will be an error in Python 3.4.
Eric Smithd44b2fc2010-04-02 12:30:56 +0000672
Antoine Pitroua57df2c2010-03-31 21:32:15 +0000673- Issue #8268: Old-style classes (not just instances) now support weak

697
Antoine Pitrouf9de5342010-04-05 21:35:07 +0000698- Issue #8321: Give access to OpenSSL version numbers from the `ssl` module,
Georg Brandlfee0f442010-05-22 21:26:21 +0000699 using the new attributes `ssl.OPENSSL_VERSION`, `ssl.OPENSSL_VERSION_INFO` and
700 `ssl.OPENSSL_VERSION_NUMBER`.

703
Georg Brandlfee0f442010-05-22 21:26:21 +0000704- Issue #8257: The Decimal construct now accepts a float instance directly,
705 converting that float to a Decimal of equal value:
Mark Dickinson8a950712010-04-03 15:47:46 +0000706
707 >>> Decimal(1.1)
708 Decimal('1.100000000000000088817841970012523233890533447265625')
709
Raymond Hettinger34c35b22010-04-03 10:22:00 +0000710- collections.Counter() now supports a subtract() method.
711
Georg Brandlfee0f442010-05-22 21:26:21 +0000712- The functools module now has a total_ordering() class decorator to simplify
713 the specification of rich comparisons.
Raymond Hettingera551f312010-04-04 18:34:45 +0000714
Georg Brandlfee0f442010-05-22 21:26:21 +0000715- The functools module also adds cmp_to_key() as a tool to transition old-style
716 comparison functions to new-style key-functions.
Raymond Hettingera551f312010-04-04 18:34:45 +0000717
Georg Brandlfee0f442010-05-22 21:26:21 +0000718- Issue #8294: The Fraction constructor now accepts Decimal and float instances
719 directly.
Mark Dickinson7c63eee2010-04-02 22:27:36 +0000720
Georg Brandlfee0f442010-05-22 21:26:21 +0000721- Issue #7279: Comparisons involving a Decimal signaling NaN now signal
722 InvalidOperation instead of returning False. (Comparisons involving a quiet
723 NaN are unchanged.) Also, Decimal quiet NaNs are now hashable; Decimal
724 signaling NaNs remain unhashable.
Mark Dickinsone096e822010-04-02 10:17:07 +0000725
Georg Brandlfee0f442010-05-22 21:26:21 +0000726- Issue #2531: Comparison operations between floats and Decimal instances now
727 return a result based on the numeric values of the operands; previously they
728 returned an arbitrary result based on the relative ordering of id(float) and
729 id(Decimal).
Mark Dickinson99d80962010-04-02 08:53:22 +0000730
Barry Warsawf7f2d6f2010-03-31 21:07:16 +0000731- Issue #8233: When run as a script, py_compile.py optionally takes a single
Georg Brandlfee0f442010-05-22 21:26:21 +0000732 argument `-` which tells it to read files to compile from stdin. Each line is
733 read on demand and the named file is compiled immediately. (Original patch by
734 Piotr Ożarowski).
Barry Warsawf7f2d6f2010-03-31 21:07:16 +0000735
Georg Brandlfee0f442010-05-22 21:26:21 +0000736- Issue #3135: Add ``inspect.getcallargs()``, which binds arguments to a

Florent Xicluna58b65662010-03-30 16:29:03 +0000739- Backwards incompatible change: Unicode codepoints line tabulation (0x0B) and
740 form feed (0x0C) are now considered linebreaks, as specified in Unicode
Georg Brandlfee0f442010-05-22 21:26:21 +0000741 Standard Annex #14. See issue #7643. http://www.unicode.org/reports/tr14/

Georg Brandlfee0f442010-05-22 21:26:21 +0000743- Comparisons using one of <, <=, >, >= between a complex instance and a
744 Fractions instance now raise TypeError instead of returning True/False. This
745 makes Fraction <=> complex comparisons consistent with int <=> complex, float
746 <=> complex, and complex <=> complex comparisons.
Mark Dickinson9588d992010-03-27 11:14:37 +0000747
Michael Foorde6410c52010-03-29 20:04:23 +0000748- Addition of ``WeakSet`` to the ``weakref`` module.

759 silenced.
Antoine Pitrou513d9ae2010-03-22 19:59:46 +0000760
Florent Xicluna9e7a4c92010-03-22 16:07:38 +0000761- Issue #7703: ctypes supports both buffer() and memoryview(). The former is

Vinay Sajipecfa08f2010-03-12 09:16:10 +0000801- Issue #8117: logging: Improved algorithm for computing initial rollover time
Georg Brandlfee0f442010-05-22 21:26:21 +0000802 for ``TimedRotatingFileHandler`` by using the modification time of an existing
803 log file to compute the next rollover time. If the log file does not exist,
804 the current time is used as the basis for the computation.
Vinay Sajip9098ee42010-03-12 06:01:21 +0000805
Georg Brandlba83f822010-03-14 09:50:54 +0000806- Issue #6472: The ``xml.etree`` package is updated to ElementTree 1.3. The

Georg Brandlfee0f442010-05-22 21:26:21 +0000853 produces a DeprecationWarning in this case. (In Python 2.6, the behaviour was
854 inconsistent: __int__ was used for some integer codes but not for others, and
855 the set of integer codes for which it was used differed between native packing
856 and standard packing.)

1053 common TestCase for some tests: test_genericpath.CommonTest.
1054
Georg Brandlba83f822010-03-14 09:50:54 +00001055- Print platform information when running the whole test suite, or using the
1056 ``--verbose`` flag.

Georg Brandlba83f822010-03-14 09:50:54 +00001061- Issue #6292: For the moment at least, the test suite runs cleanly if python
R. David Murrayf28fd242010-02-23 00:24:49 +00001062 is run with the -OO flag. Tests requiring docstrings are skipped.
1063
Georg Brandlba83f822010-03-14 09:50:54 +00001064- Issue #7712: test_support gained a new ``temp_cwd`` context manager which is
1065 now also used by regrtest to run all the tests in a temporary directory. The
1066 original CWD is saved in ``test.test_support.SAVEDCWD``. Thanks to Florent
1067 Xicluna who helped with the patch.

Antoine Pitroubb445a12010-02-05 17:05:54 +00001083- Issue #5677: Explicitly forbid write operations on read-only file objects,
1084 and read operations on write-only file objects. On Windows, the system C
Georg Brandlba83f822010-03-14 09:50:54 +00001085 library would return a bogus result; on Solaris, it was possible to crash the
1086 interpreter. Patch by Stefan Krah.

Georg Brandlba83f822010-03-14 09:50:54 +00001099- Issue #7766: Change ``sys.getwindowsversion()`` return value to a named tuple
1100 and add the additional members returned in an OSVERSIONINFOEX structure. The
1101 new members are service_pack_major, service_pack_minor, suite_mask, and
1102 product_type.

Georg Brandlba83f822010-03-14 09:50:54 +00001104- Issue #7561: Operations on empty bytearrays (such as ``int(bytearray())``)
1105 could crash in many places because of the ``PyByteArray_AS_STRING()`` macro
1106 returning NULL. The macro now returns a statically allocated empty string
1107 instead.
Antoine Pitroue80a6a42010-01-17 12:26:20 +00001108
Antoine Pitrou64672132010-01-13 07:55:48 +00001109- Issue #7622: Improve the split(), rsplit(), splitlines() and replace()

1117 strings,
1118 (2) a crash in dtoa.c that occurred in debug builds when parsing certain long
1119 numeric strings corresponding to subnormal values,
1120 (3) a memory leak for some values large enough to cause overflow, and
1121 (4) a number of flaws that could lead to incorrectly rounded results.
1122
1123- Issue #7319, #7770: Silence ``DeprecationWarning`` by default when the -3
1124 option is not used.

1139 interpreter shutdown.
1140
Georg Brandlba83f822010-03-14 09:50:54 +00001141- Issue #2746: Don't escape ampersands and angle brackets ("&", "<", ">") in

1143 by the XML specification, and are necessary when outputting e.g. PHP code in
1144 a processing instruction. Patch by Neil Muller.

Antoine Pitroud840e512010-02-04 20:20:18 +00001152- Issue #4772: Raise a ValueError when an unknown Bluetooth protocol is
Georg Brandlba83f822010-03-14 09:50:54 +00001153 specified, rather than fall through to AF_PACKET (in the ``socket`` module).
Antoine Pitroud840e512010-02-04 20:20:18 +00001154 Also, raise ValueError rather than TypeError when an unknown TIPC address
1155 type is specified. Patch by Brian Curtin.
1156
Vinay Sajip28c382f2010-02-04 18:48:53 +00001157- logging: Implemented PEP 391.

Antoine Pitrouf3fa0742010-01-31 22:26:04 +00001159- Issue #6939: Fix file I/O objects in the `io` module to keep the original
Georg Brandlba83f822010-03-14 09:50:54 +00001160 file position when calling `truncate()`. It would previously change the file
1161 position to the given argument, which goes against the tradition of
Antoine Pitrouf3fa0742010-01-31 22:26:04 +00001162 ftruncate() and other truncation APIs. Patch by Pascal Chambon.
1163
Georg Brandlba83f822010-03-14 09:50:54 +00001164- Issue #7610: Reworked implementation of the internal ``zipfile.ZipExtFile``
1165 class used to represent files stored inside an archive. The new
1166 implementation is significantly faster and can be wrapped in a
1167 ``io.BufferedReader`` object for more speedups. It also solves an issue
1168 where interleaved calls to ``read()`` and ``readline()`` give wrong results.
1169 Patch by Nir Aides.
Antoine Pitrou94c33eb2010-01-27 20:59:50 +00001170
Benjamin Peterson2deb5c72010-01-27 02:16:42 +00001171- Issue #7792: Registering non-classes to ABCs raised an obscure error.
1172
Georg Brandlba83f822010-03-14 09:50:54 +00001173- Removed the deprecated functions ``verify()`` and ``vereq()`` from

1177 when the release file is empty.
Benjamin Petersona43f34c2010-01-25 03:31:13 +00001178
Georg Brandlba83f822010-03-14 09:50:54 +00001179- Issue #7748: Since unicode values are supported for some metadata options in
1180 Distutils, the DistributionMetadata get_* methods will now return an utf-8
1181 encoded string for them. This ensures that the upload and register commands
1182 send the correct values to PyPI without any error.

1257-----------------
1258
Georg Brandlba83f822010-03-14 09:50:54 +00001259- The ``__complex__()`` method is now looked up on the class of instances to
1260 make it consistent with other special methods.
Benjamin Petersonecdae192010-01-04 00:43:01 +00001261
Antoine Pitrou5b7139a2010-01-02 21:12:58 +00001262- Issue #7462: Implement the stringlib fast search algorithm for the `rfind`,
1263 `rindex`, `rsplit` and `rpartition` methods. Patch by Florent Xicluna.
1264
Mark Dickinson1b34d252010-01-01 17:27:30 +00001265- Issue #5080: A number of functions and methods previously produced a
Georg Brandlba83f822010-03-14 09:50:54 +00001266 DeprecationWarning when passed a float argument where an integer was expected.
1267 These functions and methods now raise TypeError instead. The majority of the
1268 effects of this change are in the extension modules, but some core functions
1269 and methods are affected: notably the 'chr', 'range' and 'xrange' builtins,
1270 and many unicode/str methods.

1284 of integers: the result of a/b is now correctly rounded for ints a and b (at
1285 least on IEEE 754 platforms), and in particular does not depend on the
1286 internal representation of a long.

1294
Georg Brandlba83f822010-03-14 09:50:54 +00001295 These executables now work properly with the arch(1) command: ``arch -ppc

Georg Brandlba83f822010-03-14 09:50:54 +00001435- Issue #3382: 'F' formatting for float and complex now convert the result to
1436 upper case. This only affects 'inf' and 'nan', since 'f' no longer converts
1437 to 'g' for large values.
Amaury Forgeot d'Arcd7288712009-12-01 21:51:04 +00001438
Georg Brandlba83f822010-03-14 09:50:54 +00001439- Remove switch from "%f" formatting to "%g" formatting for floats larger than
1440 1e50 in absolute value.
Mark Dickinson9dd5e162009-11-23 20:54:09 +00001441
Georg Brandlba83f822010-03-14 09:50:54 +00001442- Remove restrictions on precision when formatting floats. E.g., "%.120g" %
1443 1e-100 used to raise OverflowError, but now gives the requested 120
1444 significant digits instead.

Ronald Oussoren315cd0c2009-11-19 16:25:21 +00001452
Georg Brandlba83f822010-03-14 09:50:54 +00001453- Issue #7117: ``repr(x)`` for a float x returns a result based on the shortest
1454 decimal string that's guaranteed to round back to x under correct rounding
1455 (with round-half-to-even rounding mode). Previously it gave a string based on
1456 rounding x to 17 decimal digits. repr(x) for a complex number behaves
1457 similarly. On platforms where the correctly-rounded strtod and dtoa code is
1458 not supported (see below), repr is unchanged.
Mark Dickinsonb678de82009-11-19 18:41:49 +00001459
Georg Brandlba83f822010-03-14 09:50:54 +00001460- Issue #7117: On almost all platforms: float-to-string and string-to-float
1461 conversions within Python are now correctly rounded. Places these conversions
1462 occur include: str for floats and complex numbers; the float and complex
1463 constructors; old-style and new-style numeric formatting; serialization and
1464 deserialization of floats and complex numbers using marshal, pickle and json;
1465 parsing of float and imaginary literals in Python code; Decimal-to-float
1466 conversion.
Mark Dickinsonb678de82009-11-19 18:41:49 +00001467
Georg Brandlba83f822010-03-14 09:50:54 +00001468 The conversions use a Python-adapted version of David Gay's well-known dtoa.c,
1469 providing correctly-rounded strtod and dtoa C functions. This code is
1470 supported on Windows, and on Unix-like platforms using gcc, icc or suncc as
1471 the C compiler. There may be a small number of platforms on which correct
1472 operation of this code cannot be guaranteed, so the code is not used: notably,
1473 this applies to platforms where the C double format is not IEEE 754 binary64,
1474 and to platforms on x86 hardware where the x87 FPU is set to 64-bit precision
1475 and Python's configure script is unable to determine how to change the FPU
1476 precision. On these platforms conversions use the platform strtod and dtoa,
1477 as before.
Mark Dickinsonb678de82009-11-19 18:41:49 +00001478
Georg Brandlba83f822010-03-14 09:50:54 +00001479- Issue #7117: Backport round implementation from Python 3.x. ``round()`` now
1480 uses the correctly-rounded string <-> float conversions described above (when
1481 available), and so produces correctly rounded results that will display nicely
1482 under the float repr. There are two related small changes: (1) round now
1483 accepts any class with an ``__index__()`` method for its second argument (but
1484 no longer accepts floats for the second argument), and (2) an excessively
1485 large second integer argument (e.g., ``round(1.234, 10**100)``) no longer
1486 raises an exception.

Georg Brandlba83f822010-03-14 09:50:54 +00001629 (1) inf and nan strings with trailing whitespace were incorrectly rejected;
1630 (2) parsing of strings representing infinities and nans was locale aware; and
1631 (3) the interpretation of fromhex('-nan') didn't match that of float('-nan').

Georg Brandlba83f822010-03-14 09:50:54 +00001633- Issue #5920: For ``float.__format__()``, change the behavior with the empty
1634 presentation type (that is, not one of 'e', 'f', 'g', or 'n') to be like 'g'
1635 but with at least one decimal point and with a default precision
1636 of 12. Previously, the behavior the same but with a default precision of 6.
1637 This more closely matches ``str()``, and reduces surprises when adding
1638 alignment flags to the empty presentation type. This also affects the new
1639 complex.__format__ in the same way.
1640
1641- Issue #5890: In subclasses of 'property' the __doc__ attribute was shadowed by

1759
Georg Brandlba83f822010-03-14 09:50:54 +00001760- Issue #4935: The overflow checking code in the expandtabs() method common to
1761 str, bytes and bytearray could be optimized away by the compiler, letting the
1762 interpreter segfault instead of raising an error.
Antoine Pitrouc2f02212009-01-13 23:13:52 +00001763
Amaury Forgeot d'Arca40d5732009-01-12 23:36:55 +00001764- Issue #3720: Fix a crash when an iterator modifies its class and removes its

1770
Antoine Pitrou4c5ecb72009-01-09 21:40:55 +00001771- Issue #4074: Change the criteria for doing a full garbage collection (i.e.
1772 collecting the oldest generation) so that allocating lots of objects without
1773 destroying them does not show quadratic performance. Based on a proposal by
Benjamin Petersond50a5d52009-07-13 00:03:20 +00001774 Martin von Löwis at

1778
Georg Brandlba83f822010-03-14 09:50:54 +00001779- Issue #1180193: When importing a module from a .pyc (or .pyo) file with an
1780 existing .py counterpart, override the co_filename attributes of all code
1781 objects if the original filename is obsolete (which can happen if the file has
1782 been renamed, moved, or if it is accessed through different paths). Patch by
1783 Ziga Seilnacht and Jean-Paul Calderone.
Antoine Pitroue96d4ea2009-01-06 18:10:47 +00001784

Hirokazu Yamamoto99a1b202009-01-01 15:45:39 +00001787- Issue #4797: IOError.filename was not set when _fileio.FileIO failed to open
1788 file with `str' filename on Windows.
1789
Antoine Pitrouaa687902009-01-01 14:11:22 +00001790- Issue #3680: Reference cycles created through a dict, set or deque iterator
1791 did not get collected.
1792
Georg Brandlba83f822010-03-14 09:50:54 +00001793- Issue #4701: PyObject_Hash now implicitly calls PyType_Ready on types where
1794 the tp_hash and tp_dict slots are both NULL.
Nick Coghlan180e4002008-12-30 01:18:48 +00001795
Benjamin Peterson7af65562008-12-29 17:56:58 +00001796- Issue #4764: With io.open, IOError.filename is set when trying to open a
1797 directory on POSIX systems.
1798
Benjamin Petersonfe231b02008-12-29 17:47:42 +00001799- Issue #4764: IOError.filename is set when trying to open a directory on POSIX
1800 systems.
1801
Georg Brandl6425a2f2008-12-28 11:54:53 +00001802- Issue #4759: None is now allowed as the first argument of
Georg Brandlba83f822010-03-14 09:50:54 +00001803 ``bytearray.translate()``. It was always allowed for ``bytes.translate()``.
Georg Brandl6425a2f2008-12-28 11:54:53 +00001804
Skip Montanarof205c132008-12-23 03:30:15 +00001805- Added test case to ensure attempts to read from a file opened for writing
1806 fail.
1807
Georg Brandlba83f822010-03-14 09:50:54 +00001808- Issue #2467: gc.DEBUG_STATS reported invalid elapsed times. Also, always print
1809 elapsed times, not only when some objects are uncollectable/unreachable.
1810 Original patch by Neil Schemenauer.
Antoine Pitrou73c0e652008-12-17 22:46:54 +00001811

Jeffrey Yasskinffd42cf2008-12-10 07:35:02 +00001821
Georg Brandlba83f822010-03-14 09:50:54 +00001822- Issue #4445: Replace ``sizeof(PyStringObject)`` with
1823 ``offsetof(PyStringObject, ob_sval) + 1`` when allocating memory for str
1824 instances. On a typical machine this saves 3 bytes of memory (on average) per
1825 string allocation.
Mark Dickinson826f3fe2008-12-05 21:55:28 +00001826
Amaury Forgeot d'Arcdc619012008-11-22 20:01:18 +00001827- Issue #3996: On Windows, the PyOS_CheckStack function would cause the
1828 interpreter to abort ("Fatal Python error: Could not reset the stack!")
1829 instead of throwing a MemoryError.
1830
Georg Brandlba83f822010-03-14 09:50:54 +00001831- Issue #3689: The list reversed iterator now supports __length_hint__ instead
1832 of __len__. Behavior now matches other reversed iterators.
Raymond Hettinger7989a4d2008-12-03 15:42:10 +00001833
Benjamin Petersonc078f922008-11-21 22:27:24 +00001834- Issue #4367: Python would segfault during compiling when the unicodedata
1835 module couldn't be imported and \N escapes were present.
1836
Georg Brandlba83f822010-03-14 09:50:54 +00001837- Issue #4233: Changed semantic of ``_fileio.FileIO``'s ``close()`` method on
1838 file objects with closefd=False. The file descriptor is still kept open but
1839 the file object behaves like a closed file. The ``FileIO`` object also got a
1840 new readonly attribute ``closefd``.
Amaury Forgeot d'Arc32265652008-11-20 23:34:31 +00001841
Benjamin Peterson46cc6d12008-11-19 21:49:09 +00001842- Issue #4348: Some bytearray methods returned that didn't cause any change to
1843 the bytearray, returned the same bytearray instead of a copy.
1844
Georg Brandlba83f822010-03-14 09:50:54 +00001845- Issue #4317: Fixed a crash in the ``imageop.rgb2rgb8()`` function.

1848
Benjamin Peterson6624a9f2008-11-03 15:14:51 +00001849- Issue #4048: The parser module now correctly validates relative imports.
1850
Benjamin Petersondcee09d2008-10-31 02:16:05 +00001851- Issue #4225: ``from __future__ import unicode_literals`` didn't work in an
1852 exec statement.
1853
Georg Brandlba83f822010-03-14 09:50:54 +00001854- Issue #4176: Fixed a crash when pickling an object which ``__reduce__`` method
1855 does not return iterators for the 4th and 5th items.
Amaury Forgeot d'Arc69a9c5b2008-10-30 21:18:34 +00001856
Benjamin Petersonbdca9422008-10-26 20:21:13 +00001857- Issue #4209: Enabling unicode_literals and the print_function in the same
1858 __future__ import didn't work.
1859
Benjamin Peterson399b1fe2008-10-25 02:53:28 +00001860- Using ``nonlocal`` as a variable name will now raise a Py3k SyntaxWarning
Georg Brandl7fb00ad2008-10-25 07:00:52 +00001861 because it is a reserved word in 3.x.
Benjamin Peterson399b1fe2008-10-25 02:53:28 +00001862
Georg Brandlba83f822010-03-14 09:50:54 +00001863- On windows, ``os.chdir()`` given unicode was not working if
1864 GetCurrentDirectoryW returned a path longer than MAX_PATH. (But It's doubtful
1865 this code path is really executed because I cannot move to such directory on
1866 win2k)
Hirokazu Yamamoto10a018c2008-10-09 10:00:30 +00001867
Georg Brandlba83f822010-03-14 09:50:54 +00001868- Issue #4069: When ``set.remove(element)`` is used with a set element, the
1869 element is temporarily replaced with an equivalent frozenset. But the
1870 eventual KeyError would always report the empty ``frozenset()`` as the missing
1871 key. Now it correctly refers to the initial element.
Amaury Forgeot d'Arcd78b9dc2008-10-07 20:32:10 +00001872
Georg Brandlba83f822010-03-14 09:50:54 +00001873- Issue #4509: Various issues surrounding resize of bytearray objects to which
1874 there are buffer exports.

1881
Georg Brandlba83f822010-03-14 09:50:54 +00001882- Issue #3845: In PyRun_SimpleFileExFlags avoid invalid memory access with short

Gregory P. Smith2b3eb372009-04-05 23:48:26 +00001888- Issue #5705: os.setuid() would not accept values > 2**31-1 but pwd.getpwnam()
1889 returned them on 64bit platforms.
1890
Walter Dörwalded960ac2009-05-03 22:36:33 +00001891- Issue #5108: Handle %s like %S and %R in PyUnicode_FromFormatV(): Call
1892 PyUnicode_DecodeUTF8() once, remember the result and output it in a second
1893 step. This avoids problems with counting UTF-8 bytes that ignores the effect
1894 of using the replace error handler in PyUnicode_DecodeUTF8().
1895
Walter Dörwald726ba8e2009-05-06 14:32:35 +00001896- Issue #3739: The unicode-internal encoder now reports the number of characters
1897 consumed like any other encoder (instead of the number of bytes).
1898
Georg Brandlba83f822010-03-14 09:50:54 +00001899- Issue #2422: When compiled with the ``--with-valgrind`` option, the pymalloc
1900 allocator will be automatically disabled when running under Valgrind. This
1901 gives improved memory leak detection when running under Valgrind, while taking
1902 advantage of pymalloc at other times.

Georg Brandlba83f822010-03-14 09:50:54 +00003125 leak-chasing test runs give sensible results. The previous method of reaping
3126 threads could return successfully while some Thread objects were still
3127 referenced. This also introduces a new private function: ``thread._count()``.

Guilherme Polo7f146ab2009-06-21 17:22:50 +00003144- Issue #5450: Moved tests involving loading tk from Lib/test/test_tcl to
3145 Lib/lib-tk/test/test_tkinter/test_loadtk. With this, these tests demonstrate
Georg Brandlba83f822010-03-14 09:50:54 +00003146 the same behaviour as test_ttkguionly (and now also test_tk) which is to skip
3147 the tests if DISPLAY is defined but can't be used.

3153 import both normal and optimised versions of modules. test_heapq and
3154 test_warnings have been adjusted to use it, tests for other modules with both
3155 C and Python implementations in the stdlib can be adjusted to use it over
3156 time.

Georg Brandlba83f822010-03-14 09:50:54 +00003164- regrtest no longer treats ImportError as equivalent to SkipTest. Imports that
3165 should cause a test to be skipped are now done using import_module from test
3166 support, which does the conversion.

3268
Amaury Forgeot d'Arc05e34492008-09-10 22:04:45 +00003269- Issue #3743: In a few places, PY_FORMAT_SIZE_T was incorrectly used with
3270 PyString_FromFormat or PyErr_Format to display size_t values. The macro
3271 PY_FORMAT_SIZE_T is designed to select the correct format for the OS
3272 ``printf`` function, whereas PyString_FromFormat has an independent
3273 implementation and uses "%zd" on all platforms for size_t values.
3274 This makes a difference on win64, where ``printf`` needs "%Id" to display
3275 64bit values.

Benjamin Peterson97179b02008-09-09 20:55:01 +00003277- Issue #3634: _weakref.ref(Exception).__init__() gave invalid return value on

3281 object; previously an int would be returned for small values. the __long__
3282 method is allowed to return either an int or a long, but the behaviour of

Antoine Pitroud4ae97b2008-08-29 18:39:48 +00003292 was correctly parsed but parsing of subsequent arguments failed.

Vinay Sajip35e3b032008-09-01 14:33:59 +00003294- Issue #2534: speed up isinstance() and issubclass() by 50-70%, so as to
Antoine Pitrou0668c622008-08-26 22:42:08 +00003295 match Python 2.5 speed despite the __instancecheck__ / __subclasscheck__
3296 mechanism. In the process, fix a bug where isinstance() and issubclass(),
3297 when given a tuple of classes as second argument, were looking up
3298 __instancecheck__ / __subclasscheck__ on the tuple rather than on each
3299 type object.

Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00003438What's New in Python 2.6 beta 3?
3439================================
3440
Barry Warsaw07a4a382008-08-21 01:15:08 +00003441*Release date: 20-Aug-2008*
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00003442
3443Core and Builtins
3444-----------------
3445
Guido van Rossumf8402962008-08-20 15:01:50 +00003446- Issue #1878: Remove Py_TPFLAGS_HAVE_VERSION_TAG from
3447 Py_TPFLAGS_DEFAULT when not building the core. This means 3rd party
3448 extensions do not automatically benefit from the class attribute
3449 cache; they will have to explicitly add Py_TPFLAGS_HAVE_VERSION_TAG
3450 to their tp_flags field if they care. This is a backwards
3451 compatibility feature; in 3.0, all types will use the cache by
3452 default.
3453
Benjamin Petersonf647dc12008-08-20 01:27:30 +00003454- Keyword arguments can now follow starred arguments. (``f(a, *args,
3455 keyword=23)`` is now valid syntax.)
3456
Thomas Heller0ad5ae02008-08-19 19:25:04 +00003457- ctypes function pointers that are COM methods have a boolean True
3458 value again.
3459
Martin v. Löwisf91d46a2008-08-12 14:49:50 +00003460- Issue #3139: Make buffer-interface thread-safe wrt. PyArg_ParseTuple,
3461 by denying s# to parse objects that have a releasebuffer procedure,
3462 and introducing s*.
3463
Georg Brandl1e13ea92008-08-11 09:07:59 +00003464- Issue #3537: Fix an assertion failure when an empty but presized dict
3465 object was stored in the freelist.
3466
Mark Dickinsonb6467572008-08-04 21:30:09 +00003467- Issue #1481296: Make long(float('nan')) and int(float('nan')) raise
3468 ValueError consistently across platforms.
3469
Amaury Forgeot d'Arc39fd6722008-07-31 21:28:03 +00003470- Issue #3479: On platforms where sizeof(int) is smaller than sizeof(long)
3471 (64bit Unix, for example), unichr() would truncate its argument and return
3472 u'\x00' for unichr(2**32). Now it properly raises an OverflowError.
3473
Neal Norwitze7d8be82008-07-31 17:17:14 +00003474- Apply security patches from Apple.
3475
Amaury Forgeot d'Arc246daed2008-07-31 00:42:16 +00003476- Issue #2542: Now that issubclass() may call arbitrary code, ensure that
3477 PyErr_ExceptionMatches returns 0 when an exception occurs there.
3478
Antoine Pitrou92f82162008-07-25 22:22:08 +00003479- Issue #1819: function calls with several named parameters are now on
3480 average 35% faster (as measured by pybench).
3481
Amaury Forgeot d'Arce4921fe2008-07-21 22:00:38 +00003482- Issue #2378: An unexpected UnboundLocalError or NameError could appear when
3483 the python debugger steps into a class statement: the free variables (local
3484 variables defined in an outer scope) would be deleted from the outer scope.
3485
Gregory P. Smith0470bab2008-07-22 04:46:32 +00003486- Issue #2620: Overflow checking when allocating or reallocating memory
3487 was not always being done properly in some python types and extension
3488 modules. PyMem_MALLOC, PyMem_REALLOC, PyMem_NEW and PyMem_RESIZE have
3489 all been updated to perform better checks and places in the code that
3490 would previously leak memory on the error path when such an allocation
3491 failed have been fixed.
3492

3494-------
3495
Hirokazu Yamamoto838c79f2008-08-20 13:14:07 +00003496- Issue #3612: Added some missing basic types in ctypes.wintypes.
3497
Benjamin Petersone977ad42008-08-20 01:42:01 +00003498- The methods ``is_in_tuple()``, ``is_vararg()``, and ``is_keywordarg()`` of
3499 symtable.Symbol have been deprecated for removal in 3.0 and the next release.
3500
Amaury Forgeot d'Arc351ffb82008-08-18 19:23:47 +00003501- Issue #2234: distutils failed for some versions of the cygwin compiler. The
3502 version reported by these tools does not necessarily follow the python
3503 version numbering scheme, so the module is less strict when parsing it.
3504
Nick Coghlanf70385a2008-08-18 12:42:46 +00003505- Issue #2235: Added Py3k warnings for types which will become unhashable
3506 under the stricter __hash__ inheritance rules in 3.0. Several types
3507 which did not meet the rules for hash invariants and were already
3508 unhashable in 3.0 have now been explicitly flagged as unhashable in
3509 2.6 as well (collections.Mapping, collections.Set, unittest.TestSuite,
3510 xml.dom.minidom.NamedNodeMap, numbers.Number, UserList.UserList)
3511
Brett Cannon88f801d2008-08-18 00:46:22 +00003512- Update __all__ for cookielib, csv, os, urllib2, and weakref to include things
3513 imported into the module but exposed as part of the module's API.
3514
Brett Cannon7b96f072008-08-18 00:41:11 +00003515- Remove an unneeded import of abc.ABCMeta from 'inspect'.
3516
Brett Cannon46225e72008-08-18 00:36:52 +00003517- Remove unneeded imports of 'sys' and 'warnings' from 'io'.
3518
Brett Cannon25c9d6a2008-08-17 22:10:11 +00003519- Remove unneeded imports of 'warnings' from shelve, filecmp, and dummy_thread.
3520
Hirokazu Yamamoto41a81eb2008-08-17 13:10:46 +00003521- Issue #3575: Incremental decoder's decode function now takes bytearray
3522 by using 's*' instead of 't#'.
3523
Mark Dickinson3e4caeb2009-02-21 20:27:01 +00003524- Issue #2222: Fixed reference leak when occurred os.rename()
Hirokazu Yamamoto7f30a682008-08-17 09:46:56 +00003525 fails unicode conversion on 2nd parameter. (windows only)
3526
Georg Brandl222e2082010-08-01 22:27:39 +00003527- Issue #2464: urllib2 now supports a malformation in the URL received
Facundo Batista94f243a2008-08-17 03:38:39 +00003528 in a redirect.
3529
Brett Cannonabe423e2008-08-16 21:47:07 +00003530- Silence the DeprecationWarning raised when importing mimetools in
Brett Cannon721b1452008-08-16 22:00:27 +00003531 BaseHTTPServer, cgi (and rfc822), httplib.
Brett Cannonabe423e2008-08-16 21:47:07 +00003532
Facundo Batistaeb90b782008-08-16 14:44:07 +00003533- Issue #2776: fixed small issue when handling an URL with double slash
3534 after a 302 response in the case of not going through a proxy.
3535
Antoine Pitroub90a8be2008-08-15 21:03:21 +00003536- Issue #2676: in the email package, content-type parsing was hanging on
3537 pathological input because of quadratic or exponential behaviour of a
3538 regular expression.
3539
Antoine Pitrou11ec65d2008-08-14 21:04:30 +00003540- Issue #3476: binary buffered reading through the new "io" library is now
3541 thread-safe.
3542
Brett Cannonbf3157b2008-08-14 05:00:03 +00003543- Silence the DeprecationWarning of rfc822 when it is imported by mimetools
3544 since mimetools itself is deprecated. Because modules are cached, all
3545 subsequent imports of rfc822 will not raise a visible DeprecationWarning.
3546
Antoine Pitrou9fcd4b32008-08-11 17:21:36 +00003547- Issue #3134: shutil referenced undefined WindowsError symbol.
3548
Robert Schuppenies14646332008-08-10 11:01:53 +00003549- Issue #1342811: Fix leak in Tkinter.Menu.delete. Commands associated to
3550 menu entries were not deleted.
3551
Brett Cannon83e81842008-08-09 23:30:55 +00003552- Copied the implementation of reduce() to _functools.reduce() to have a
3553 version that did not raise a DeprecationWarning under -3.
3554
Antoine Pitrou76b8bee2008-08-09 17:27:23 +00003555- Issue #3205: When iterating over a BZ2File fails allocating memory, raise
3556 a MemoryError rather than silently stop the iteration.
3557
Guido van Rossum59ce9012008-08-09 14:55:34 +00003558- Issue #3487: sre "bytecode" validator. Passing invalid "re-bytecode"
3559 to _sre.compile() will now be rejected. This should not affect anybody
3560 since the re.compile() function never generates invalid re-bytecode.
3561
Skip Montanaroa032bf42008-08-08 22:52:51 +00003562- Issue #3436: Make csv.DictReader's fieldnames attribute a property so that
3563 upon first access it can be automatically initialized from the csv file if
3564 it wasn't initialized during instantiation.
3565
Brett Cannon3aa2a492008-08-06 22:28:09 +00003566- Issue #2338: Create imp.reload() to help with transitioning to Python 3.0 as
3567 the reload() built-in has been removed.
3568
Brett Cannon7e30b672008-08-04 21:52:25 +00003569- Changed code in the following modules/packages to remove warnings raised
Brett Cannonc1b76e42008-08-09 23:06:16 +00003570 while running under the ``-3`` flag: aifc, asynchat, asyncore, bdb, bsddb,

3573 pstats, pydoc, re, rlcompleter, SimpleXMLRPCServer, shelve, socket,
3574 subprocess, sqlite3, tarfile, Tkinter, test.test_support, textwrap,
3575 threading, tokenize, traceback, urlparse, wsgiref, xml, xmlrpclib.
Brett Cannon7e30b672008-08-04 21:52:25 +00003576
Lars Gustäbel727bd0b2008-08-02 11:26:39 +00003577- Issue #3039: Fix tarfile.TarFileCompat.writestr() which always
3578 raised an AttributeError.
3579
Benjamin Peterson01a24322008-07-28 23:35:27 +00003580- Issue #2523: Fix quadratic behaviour when read()ing a binary file without
Antoine Pitroude781a42008-08-09 12:43:23 +00003581 asking for a specific length. This problem only affected files opened
3582 using the new "io" module, not the built-in open() function.
Benjamin Peterson01a24322008-07-28 23:35:27 +00003583
Mark Dickinsonfe84cce2008-07-27 06:39:07 +00003584- Issue #3449: Update decimal module to use most recent specification
3585 (v. 1.68) and tests (v. 2.58) from IBM.
3586
Georg Brandl222e2082010-08-01 22:27:39 +00003587- Issue #3437: Bug fix in robotparser parsing of Allow: lines.
Skip Montanarof9ac43f2008-07-27 00:50:41 +00003588

3591
Georg Brandlf9efabb2008-07-23 15:16:45 +00003592- Deprecate the "ast" parser function aliases.
3593
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00003594- Issue #3120: On 64-bit Windows the subprocess module was truncating handles.
3595
3596- Issue #3303: Fix a crash in locale.strcoll() when calling it with
3597 invalid arguments.
3598
3599- Issue #3302: Fix several crashes when calling locale's gettext functions
3600 with None arguments.
3601
3602- Issue #3389: Allow resolving dotted names for handlers in logging
3603 configuration files.
3604
3605- Deprecate the sunaudio module for removal in Python 3.0.
3606
Antoine Pitrou5fdfa3e2008-07-25 19:42:26 +00003607- Issue #3394: zipfile.writestr sets external attributes when passed a
3608 file name rather than a ZipInfo instance, so files are extracted with
3609 mode 0600 rather than 000 under Unix.
3610
Gregory P. Smitha36f8fe2008-08-04 00:13:29 +00003611- Issue #1857: subprocess.Popen.poll gained an additional _deadstate keyword
3612 argument in python 2.5, this broke code that subclassed Popen to include its
3613 own poll method. Fixed my moving _deadstate to an _internal_poll method.

3624 interaction with the tp_hash slot (added in 2.6b2) are now documented
3625
Nick Coghlan2a0c2b12008-08-04 12:47:17 +00003626- Issue #643841: The language reference now provides more detailed
3627 coverage of the lookup process for special methods. The disclaimers
3628 regarding lack of coverage of new-style classes have also been
3629 removed, since the coverage is now fairly reasonable.

3633================================
3634
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00003635*Release date: 17-Jul-2008*

Raymond Hettingere3ae6552008-06-20 04:18:15 +00003637Core and Builtins
3638-----------------
3639
Georg Brandl3e483f62008-07-16 22:57:41 +00003640- Issue #3156: Fix inconsistent behavior of the bytearray type: all
3641 its methods now allow for items objects that can be converted to
3642 an integer using operator.index().
3643
Mark Dickinson64b7e502008-07-16 09:40:03 +00003644- Issue #3360: Fix incorrect parsing of '020000000000.0', which
3645 produced a ValueError instead of giving the correct float.
3646
Eric Smitha5fa5a22008-07-16 00:11:49 +00003647- Issue #3083: Add alternate (#) formatting for bin, oct, hex output
3648 for str.format(). This adds the prefix 0b, 0o, or 0x, respectively.
3649
Mark Dickinson7103aa42008-07-15 19:08:33 +00003650- Issue #3008: the float type has a new instance method 'float.hex'
3651 and a new class method 'float.fromhex' to convert floating-point
3652 numbers to and from hexadecimal strings, respectively.
3653
Nick Coghlan6d6bd442008-07-15 15:40:22 +00003654- Issue #2235: __hash__ is once again inherited by default. To allow
3655 collections.Hashable to remain meaningful in the presence of the
3656 default hash implementation (object.__hash__), it is now possible
3657 to explicit block inheritance of hash by setting __hash__=None at
3658 the Python level, or tp_hash=PyObject_HashNotImplemented at the C
3659 level.
3660
Nick Coghlanb028f502008-07-13 14:52:36 +00003661- Issue #3221: Issue a RuntimeWarning instead of raising SystemError if
3662 the parent module cannot be found while performing an absolute import.
3663 This means that an incorrectly defined __package__ attribute will
3664 now only prevent relative imports in that module rather than causing
3665 all imports from that module to fail.
3666
Nick Coghlan14ff9942008-07-08 14:21:42 +00003667- Issue #2517: Allow unicode messages in Exceptions again by correctly
3668 bypassing the instance dictionary when looking up __unicode__ on
3669 new-style classes.
3670
Amaury Forgeot d'Arcbdd941f2008-07-01 20:38:04 +00003671- Issue #3242: Fix a crash inside the print statement, if sys.stdout is
3672 set to a custom object whose write() method happens to install
3673 another file in sys.stdout.
3674
Amaury Forgeot d'Arc1f40c8a2008-06-30 22:42:40 +00003675- Issue #3088: Corrected a race condition in classes derived from
3676 threading.local: the first member set by a thread could be saved in
3677 another thread's dictionary.
3678
Mark Dickinson1ec2fcd2008-06-20 14:53:43 +00003679- Issue #3004: Minor change to slice.indices(): the start and stop
3680 arguments are now treated identically, making the behaviour easier
3681 to describe and understand. For example, slice(None, -10,
3682 1).indices(9) now returns (0, 0, 1) instead of (0, -1, 1), and
3683 slice(None, 10, -1).indices(10) returns (9, 9, -1) instead of (9,
3684 10, -1).
3685
Georg Brandl278fc502008-07-19 12:46:12 +00003686- Issue #3219: Calling a function with repeated keyword arguments,
3687 f(a=2, a=23), would not cause a syntax error. This was a regression
3688 from 2.4 caused by the switch to the new compiler.

Georg Brandl5cc774e2008-06-11 20:28:06 +00004138 PPC64 and x86_64 support in one binary).
Ronald Oussoren5640ce22008-06-05 12:58:24 +00004139
4140 This is controlled by the configure argument ``--with-universal-archs``:
4141

4143
4144 - ``--with-universal-archs=32-bit``: install 2-way universal, 32-bit (the default)
4145
4146 - ``--with-universal-archs=64-bit``: install 2-way universal, 64-bit
4147

Georg Brandl3ee81df2008-05-17 18:14:43 +00004200- Issue #1631171: Re-implement the 'warnings' module in C (the
4201 original Python code has been kept as backup). This will allow for
4202 using the 'warning's machinery in such places as the parser where
4203 use of pure Python code is not possible. Both the ``showarning()``
4204 and ``formatwarning()`` gain an optional 'line' argument which is
4205 not called by default for backwards-compatibility reasons. Setting
4206 ``warnings.showwarning()`` to an implementation that lacks support
4207 for the ``line`` argument will raise a DeprecationWarning.

Georg Brandl3ee81df2008-05-17 18:14:43 +00004270- Issue #2550: The approach used by client/server code for obtaining
4271 ports to listen on in network-oriented tests has been refined in an
4272 effort to facilitate running multiple instances of the entire
4273 regression test suite in parallel without issue.
4274 test_support.bind_port() has been fixed such that it will always
4275 return a unique port -- which wasn't always the case with the
4276 previous implementation, especially if socket options had been set
4277 that affected address reuse (i.e. SO_REUSEADDR, SO_REUSEPORT). The
4278 new implementation of bind_port() will actually raise an exception
4279 if it is passed an AF_INET/SOCK_STREAM socket with either the
4280 SO_REUSEADDR or SO_REUSEPORT socket option set. Furthermore, if
4281 available, bind_port() will set the SO_EXCLUSIVEADDRUSE option on
4282 the socket it's been passed. This currently only applies to
4283 Windows. This option prevents any other sockets from binding to the
4284 host/port we've bound to, thus removing the possibility of the
4285 'non-deterministic' behaviour, as Microsoft puts it, that occurs
4286 when a second SOCK_STREAM socket binds and accepts to a host/port
4287 that's already been bound by another socket. The optional preferred
4288 port parameter to bind_port() has been removed. Under no
4289 circumstances should tests be hard coding ports!
4290
4291 test_support.find_unused_port() has also been introduced, which will
4292 pass a temporary socket object to bind_port() in order to obtain an
4293 unused port. The temporary socket object is then closed and
4294 deleted, and the port is returned. This method should only be used
4295 for obtaining an unused port in order to pass to an external program
4296 (i.e. the -accept [port] argument to openssl's s_server mode) or as
4297 a parameter to a server-oriented class that doesn't give you direct
4298 access to the underlying socket used.
4299
4300 Finally, test_support.HOST has been introduced, which should be used
4301 for the host argument of any relevant socket calls (i.e. bind and
4302 connect).
Trent Nelsone41b0062008-04-08 23:47:30 +00004303
4304 The following tests were updated to following the new conventions:
Georg Brandl3ee81df2008-05-17 18:14:43 +00004305 test_socket, test_smtplib, test_asyncore, test_ssl, test_httplib,
Trent Nelsone41b0062008-04-08 23:47:30 +00004306 test_poplib, test_ftplib, test_telnetlib, test_socketserver,
4307 test_asynchat and test_socket_ssl.
4308
Georg Brandl3ee81df2008-05-17 18:14:43 +00004309 It is now possible for multiple instances of the regression test
4310 suite to run in parallel without issue.

Thomas Heller78b8f442008-03-05 14:53:39 +00004514- The bundled libffi copy is now in sync with the recently released
4515 libffi3.0.4 version, apart from some small changes to
Georg Brandl3ee81df2008-05-17 18:14:43 +00004516 Modules/_ctypes/libffi/configure.ac. On OS X, preconfigured libffi
4517 files are used. On all linux systems the --with-system-ffi
4518 configure option defaults to "yes".

Eric Smitha73fbe72008-02-23 03:09:44 +00004589- Added the future_builtins module, which contains hex() and oct().
4590 These are the PEP 3127 version of these functions, designed to be
4591 compatible with the hex() and oct() builtins from Python 3.0. They
4592 differ slightly in their output formats from the existing, unchanged
4593 Python 2.6 builtins. The expected usage of the future_builtins
4594 module is:
4595 from future_builtins import hex, oct
4596
Eric Smith7ef40bf2008-02-20 23:34:22 +00004597- Issue #1600: Modifed PyOS_ascii_formatd to use at most 2 digit
4598 exponents for exponents with absolute value < 100. Follows C99
4599 standard. This is a change on Windows, which would use 3 digits.
4600 Also, added 'n' to the formats that PyOS_ascii_formatd understands,
4601 so that any alterations it does to the resulting string will be
4602 available in stringlib/formatter.h (for float.__format__).
4603
Eric Smith5a3c1352008-02-19 13:21:56 +00004604- Implemented PEP 3101, Advanced String Formatting. This adds a new
4605 builtin format(); a format() method for str and unicode; a
4606 __format__() method to object, str, unicode, int, long, float, and
4607 datetime; the class string.Formatter; and the C API
4608 PyObject_Format().
4609
Georg Brandl3ee81df2008-05-17 18:14:43 +00004610- Fixed several potential crashes, all caused by specially crafted
4611 __del__ methods exploiting objects in temporarily inconsistent
4612 state.
Amaury Forgeot d'Arc632fad32008-02-16 20:55:24 +00004613
Vinay Sajipb7edfc42008-04-02 21:10:23 +00004614- Issue #2115: Important speedup in setting __slot__ attributes. Also
Georg Brandl3ee81df2008-05-17 18:14:43 +00004615 prevent a possible crash: an Abstract Base Class would try to access
4616 a slot on a registered virtual subclass.
Amaury Forgeot d'Arc60d6c7f2008-02-15 21:22:45 +00004617

Georg Brandl3ee81df2008-05-17 18:14:43 +00004621- Clear all free lists during a gc.collect() of the highest generation
4622 in order to allow pymalloc to free more arenas. Python may give back
4623 memory to the OS earlier.
Christian Heimes3b718a72008-02-14 12:47:33 +00004624
Georg Brandl3ee81df2008-05-17 18:14:43 +00004625- Issue #2045: Fix an infinite recursion triggered when printing a
4626 subclass of collections.defaultdict, if its default_factory is set
4627 to a bound method.
Amaury Forgeot d'Arcb01aa432008-02-08 00:56:02 +00004628
Christian Heimesf75dbef2008-02-08 00:11:31 +00004629- Fixed a minor memory leak in dictobject.c. The content of the free
4630 list was not freed on interpreter shutdown.
4631
Georg Brandl21e99f42010-03-07 15:23:59 +00004632- Limit free list of method and built-in function objects to 256
Georg Brandl3ee81df2008-05-17 18:14:43 +00004633 entries each.
Christian Heimes6075a822008-02-06 12:44:34 +00004634
Georg Brandl3ee81df2008-05-17 18:14:43 +00004635- Patch #1953: Added ``sys._compact_freelists()`` and the C API
4636 functions ``PyInt_CompactFreeList`` and ``PyFloat_CompactFreeList``
Christian Heimes422051a2008-02-04 18:00:12 +00004637 to compact the internal free lists of pre-allocted ints and floats.
4638
Georg Brandl3ee81df2008-05-17 18:14:43 +00004639- Issue #1983: Fixed return type of fork(), fork1() and forkpty()
4640 calls. Python expected the return type int but the fork familie
4641 returns pi_t.
Christian Heimes951cc0f2008-01-31 23:08:23 +00004642
Georg Brandl3ee81df2008-05-17 18:14:43 +00004643- Issue #1678380: Fix a bug that identifies 0j and -0j when they
4644 appear in the same code unit.
Mark Dickinson105be772008-01-31 22:17:37 +00004645

Georg Brandl3ee81df2008-05-17 18:14:43 +00004655- Patch #1473257: generator objects gain a gi_code attribute. This is
4656 the same object as the func_code attribute of the function that
4657 produced the generator.
Georg Brandl0cdf9a32008-01-26 14:14:20 +00004658
Georg Brandl3ee81df2008-05-17 18:14:43 +00004659- Issue #1920: "while 0" statements were completely removed by the
4660 compiler, even in the presence of an "else" clause, which is
4661 supposed to be run when the condition is false. Now the compiler
4662 correctly emits bytecode for the "else" suite.
Amaury Forgeot d'Arc31eaafe2008-01-24 22:59:25 +00004663
Guido van Rossumeead05f2008-01-24 18:21:02 +00004664- A few crashers fixed: weakref_in_del.py (issue #1377858);
4665 loosing_dict_ref.py (issue #1303614, test67.py);
4666 borrowed_ref_[34].py (not in tracker).
4667
Vinay Sajipd7cf32e2008-01-24 12:43:33 +00004668- Issue #1069410: The "can't load dll" message box on Windows is
Christian Heimesb2302ba2008-01-23 17:15:06 +00004669 suppressed while an extension is loaded by calling SetErrorMode in
4670 dynload_win.c. The error is still reported properly.
4671
Georg Brandl3ee81df2008-05-17 18:14:43 +00004672- Issue #1915: Python compiles with --enable-unicode=no again. However
Christian Heimes082c9b02008-01-23 14:20:50 +00004673 several extension methods and modules do not work without unicode
4674 support.
4675
Georg Brandl26543b12008-01-21 18:36:51 +00004676- Issue #1882: when compiling code from a string, encoding cookies in the
4677 second line of code were not always recognized correctly.
4678
Georg Brandl14404b62008-01-19 19:27:05 +00004679- Issue #1679: "0x" was taken as a valid integer literal.
4680
Georg Brandl6caad7d2008-01-26 14:19:22 +00004681- Issue #1865: ``bytes`` as an alias for ``str`` and b"" as an alias "" were
Christian Heimes288e89a2008-01-18 18:24:07 +00004682 added.
4683
Christian Heimesc94e2b52008-01-14 04:13:37 +00004684- sys.float_info / PyFloat_GetInfo: The floating point information
4685 object was converted from a dict to a specialized structseq object.
4686
Georg Brandl3ee81df2008-05-17 18:14:43 +00004687- Patch #1816: Added sys.flags structseq. It exposes the status of
4688 most command line arguments and PYTHON* environment variables.
Christian Heimesf31b69f2008-01-14 03:42:48 +00004689
Georg Brandl3ee81df2008-05-17 18:14:43 +00004690- Objects/structseq.c: Implemented new structseq representation. The

4692 readable.
Christian Heimes9c201962008-01-14 03:33:52 +00004693
Georg Brandl3ee81df2008-05-17 18:14:43 +00004694- Patch #1700288: added a type attribute cache that caches method

Georg Brandl3ee81df2008-05-17 18:14:43 +00004706- Improve some exception messages when Windows fails to load an
4707 extension module. Now we get for example '%1 is not a valid Win32
4708 application' instead of 'error code 193'.

Georg Brandl3ee81df2008-05-17 18:14:43 +00004716 and INF. float("nan"), float("inf") and float("-inf") now work on
4717 every platform with IEEE 754 semantics.
Christian Heimes0a8143f2007-12-18 23:22:54 +00004718
Georg Brandl3ee81df2008-05-17 18:14:43 +00004719- Compiler now generates simpler and faster code for dictionary
4720 literals. The oparg for BUILD_MAP now indicates an estimated
4721 dictionary size. There is a new opcode, STORE_MAP, for adding
4722 entries to the dictionary.

Georg Brandl3ee81df2008-05-17 18:14:43 +00004751- Patch #1739468: Directories and zipfiles containing a __main__.py
4752 file can now be directly executed by passing their name to the
4753 interpreter. The directory/zipfile is automatically inserted as the
4754 first entry in sys.path.

Georg Brandl3ee81df2008-05-17 18:14:43 +00004756- Issue #1265: Fix a problem with sys.settrace, if the tracing
4757 function uses a generator expression when at the same time the
4758 executed code is closing a paused generator.
Amaury Forgeot d'Arc0d75f092007-11-13 21:54:28 +00004759
Raymond Hettinger1760c8a2007-11-08 02:52:43 +00004760- sets and frozensets now have an isdisjoint() method.

4763
Neal Norwitz44f326e2007-10-05 05:29:17 +00004764- Fix warnings found by the new version of the Coverity checker.
4765
Georg Brandl21e99f42010-03-07 15:23:59 +00004766- The enumerate() built-in function is no longer bounded to sequences
Georg Brandl3ee81df2008-05-17 18:14:43 +00004767 smaller than LONG_MAX. Formerly, it raised an OverflowError. Now,
4768 automatically shifts from ints to longs.
Raymond Hettinger8f669372007-10-03 21:18:11 +00004769
Georg Brandl3ee81df2008-05-17 18:14:43 +00004770- Issue #1686386: Tuple's tp_repr did not take into account the
4771 possibility of having a self-referential tuple, which is possible
4772 from C code. Nor did object's tp_str consider that a type's tp_str
4773 could do something that could lead to an inifinite recursion.
4774 Py_ReprEnter() and Py_EnterRecursiveCall(), respectively, fixed the
4775 issues.
Brett Cannon0b14f242007-09-30 19:45:10 +00004776
Georg Brandl3ee81df2008-05-17 18:14:43 +00004777- Issue #1164: It was possible to trigger deadlock when using the
4778 'print' statement to write to a file since the GIL was not released
4779 as needed. Now PyObject_Print() does the right thing along with
4780 various tp_print implementations of the built-in types and those in
4781 the collections module.
Brett Cannon01531592007-09-17 03:28:34 +00004782
Georg Brandl3ee81df2008-05-17 18:14:43 +00004783- Issue #1147: Exceptions were directly allowing string exceptions in
4784 their throw() method even though string exceptions no longer
4785 allowed.
Brett Cannon4c20bc42007-09-11 21:02:28 +00004786
Georg Brandl3ee81df2008-05-17 18:14:43 +00004787- Issue #1096: Prevent a segfault from getting the repr of a very
4788 deeply nested list by using the recursion counter.
Brett Cannona0c05512007-09-10 21:38:27 +00004789
Brett Cannon1e534b52007-09-07 04:18:30 +00004790- Issue #1202533: Fix infinite recursion calls triggered by calls to
Georg Brandl3ee81df2008-05-17 18:14:43 +00004791 PyObject_Call() never calling back out to Python code to trigger
4792 recursion depth updates/checks. Required the creation of a static
4793 RuntimeError instance in case normalizing an exception put the
4794 recursion check value past its limit. Fixes crashers
4795 infinite_rec_(1|2|4|5).py.
Brett Cannon1e534b52007-09-07 04:18:30 +00004796
Georg Brandl3ee81df2008-05-17 18:14:43 +00004797- Patch #1031213: Decode source line in SyntaxErrors back to its

Neal Norwitz0ac60192007-05-27 04:08:54 +00004810- Add new attribute names for function objects. All the func_* become
Georg Brandl3ee81df2008-05-17 18:14:43 +00004811 __*__ attributes. (Some already existed, e.g., __doc__ and
4812 __name__.)
Neal Norwitz0ac60192007-05-27 04:08:54 +00004813
Neal Norwitz8b2bfbc2007-05-23 06:35:32 +00004814- Add -3 option to the interpreter to warn about features that are
4815 deprecated and will be changed/removed in Python 3.0.
4816
Georg Brandl2134e752007-05-21 20:34:16 +00004817- Patch #1686487: you can now pass any mapping after '**' in function
4818 calls.
4819
Collin Winter62903052007-05-18 23:11:24 +00004820- except clauses may now be spelled either "except E, target:" or
Georg Brandl3ee81df2008-05-17 18:14:43 +00004821 "except E as target:". This is to provide forwards compatibility
4822 with Python 3.0.
Collin Winter62903052007-05-18 23:11:24 +00004823
Brett Cannon229cee22007-05-05 01:34:02 +00004824- Deprecate BaseException.message as per PEP 352.
4825
Georg Brandl3ee81df2008-05-17 18:14:43 +00004826- Issue #1303614: don't expose object's __dict__ when the dict is
Georg Brandl21e99f42010-03-07 15:23:59 +00004827 inherited from a built-in base.
Armin Rigo9790a272007-05-02 19:23:31 +00004828
Vinay Sajip8549ce32007-05-06 17:53:37 +00004829- When __slots__ are set to a unicode string, make it work the same as
Neal Norwitzcbd9ee62007-04-14 05:25:50 +00004830 setting a plain string, ie don't expand to single letter identifiers.
4831
Raymond Hettinger13936692007-04-11 18:40:58 +00004832- Request #1191699: Slices can now be pickled.
4833
Raymond Hettinger4db5fe92007-04-12 04:10:00 +00004834- Request #1193128: str.translate() now allows a None argument for
4835 translations that only remove characters without re-mapping the
4836 remaining characters.
4837
Georg Brandl5cb76c12007-03-21 09:00:39 +00004838- Patch #1682205: a TypeError while unpacking an iterable is no longer
4839 masked by a generic one with the message "unpack non-sequence".
4840
Neal Norwitzaa754b72007-03-21 06:39:48 +00004841- Remove unused file Python/fmod.c.
4842
Guido van Rossum143b5642007-03-23 04:58:42 +00004843- Bug #1683368: The object.__init__() and object.__new__() methods are
4844 now stricter in rejecting excess arguments. The only time when
4845 either allows excess arguments is when it is not overridden and the
4846 other one is. For backwards compatibility, when both are
4847 overridden, it is a deprecation warning (for now; maybe a Py3k
Guido van Rossum234b1ff2007-03-23 19:39:01 +00004848 warning later). Also, type.__init__() insists on the same signature
4849 as supported by type.__new__().
Guido van Rossum143b5642007-03-23 04:58:42 +00004850
Georg Brandl3ee81df2008-05-17 18:14:43 +00004851- Patch #1675423: PyComplex_AsCComplex() now tries to convert an
4852 object to complex using its __complex__() method before falling back
4853 to the __float__() method. Therefore, the functions in the cmath
4854 module now can operate on objects that define a __complex__()
4855 method.
Georg Brandl2b869942007-03-17 16:08:45 +00004856
Georg Brandl3ee81df2008-05-17 18:14:43 +00004857- Patch #1623563: allow __class__ assignment for classes with
4858 __slots__. The old and the new class are still required to have the
4859 same slot names.
Žiga Seilnacht6f2d09c2007-03-16 11:59:38 +00004860

4865 ``object.__reduce_ex__()`` is called with an object that is faking
4866 its type.
Žiga Seilnacht20f43d32007-03-15 11:44:55 +00004867
Georg Brandl3ee81df2008-05-17 18:14:43 +00004868- Patch #1680015: Don't modify __slots__ tuple if it contains an

4872
Georg Brandl7b9c5552007-03-12 14:30:05 +00004873- Bug #1678647: write a newline after printing an exception in any
4874 case, even when converting the value to a string failed.
4875
Georg Brandl871f1bc2007-03-12 13:17:36 +00004876- The dir() function has been extended to call the __dir__() method on
Georg Brandl3ee81df2008-05-17 18:14:43 +00004877 its argument, if it exists. If not, it will work like before. This
4878 allows customizing the output of dir() in the presence of a
4879 __getattr__().

4883
Georg Brandl3ee81df2008-05-17 18:14:43 +00004884- Patch #1675981: remove unreachable code from ``type.__new__()``

Georg Brandl3ee81df2008-05-17 18:14:43 +00004887- Patch #1491866: change the complex() constructor to allow
4888 parthensized forms. This means complex(repr(x)) now works instead of
4889 raising a ValueError.
Collin Wintere38051d2007-03-09 20:33:07 +00004890
Georg Brandlaa2321b2007-03-07 00:40:28 +00004891- Patch #703779: unset __file__ in __main__ after running a file. This
Georg Brandl3ee81df2008-05-17 18:14:43 +00004892 makes the filenames the warning module prints much more sensible
4893 when a PYTHONSTARTUP file is used.
Georg Brandlaa2321b2007-03-07 00:40:28 +00004894

Georg Brandl0fca97a2007-03-05 22:28:08 +00004906- Patch #1674228: when assigning a slice (old-style), check for the
4907 sq_ass_slice instead of the sq_slice slot.
4908
Georg Brandl3ee81df2008-05-17 18:14:43 +00004909- When printing an unraisable error, don't print exceptions. before
4910 the name. This duplicates the behavior whening normally printing
4911 exceptions.

5539 -- the failure just occurred later, with a more cumbersome
5540 exception.

Georg Brandl3ee81df2008-05-17 18:14:43 +00005821- Issue #829951: In the smtplib module, SMTP.starttls() now complies
5822 with RFC 3207 and forgets any knowledge obtained from the server not
5823 obtained from the TLS negotiation itself. Patch contributed by Bill
5824 Fenner.
Gregory P. Smith2b3ba582008-01-17 08:03:17 +00005825
Georg Brandl3ee81df2008-05-17 18:14:43 +00005826- Issue #1339: The smtplib.SMTP class has been refactored a bit such
Gregory P. Smithbde4ae42008-01-17 08:35:49 +00005827 that the SMTP.starttls() caller no longer needs to call ehlo()
5828 beforehand. SMTP.starttls() now raises an exception of the server
Georg Brandl3ee81df2008-05-17 18:14:43 +00005829 does not claim to support starttls. Adds the
5830 SMTP.ehlo_or_helo_if_needed() method. Patch contributed by Bill

5911 complex, tuple, list, dict, set, and frozenset. Formerly, it would
5912 silently miscode subclasses of those types. Now, it raises a
5913 ValueError instead.
Raymond Hettinger12e94202007-11-07 01:13:09 +00005914

Georg Brandl3ee81df2008-05-17 18:14:43 +00005929 time so that opening a database previously created with the DB_DUP
5930 or DB_DUPSORT flag set will keep the proper behavior on subsequent
5931 opens. Specifically: dictionary assignment to a DB object will
5932 replace all values for a given key when the database allows
5933 duplicate values. DB users should use DB.put(k, v) when they want
5934 to store duplicates; not DB[k] = v.
Gregory P. Smithec10a4a2007-11-05 02:32:26 +00005935

5941 characters with ASCII value less than 32. Also, it correctly quotes
5942 dots only if they occur on a single line, as opposed to the previous
5943 behavior of quoting dots if they are the second character of any
5944 line.
Georg Brandl4aef7272007-03-13 22:49:43 +00005945

6267-----
6268
Georg Brandl3ee81df2008-05-17 18:14:43 +00006269- Unified naming convention for free lists and their limits. All free
6270 lists in Object/ are named ``free_list``, the counter ``numfree``
6271 and the upper limit is a macro ``PyName_MAXFREELIST`` inside an
6272 #ifndef block.
Christian Heimes5b970ad2008-02-06 13:33:44 +00006273
Georg Brandl3ee81df2008-05-17 18:14:43 +00006274- ``PySet_Add()`` can now modify a newly created frozenset. Similarly
6275 to ``PyTuple_SetItem``, it can be used to populate a brand new
6276 frozenset; but it does not steal a reference to the added item.

6288
Georg Brandl3ee81df2008-05-17 18:14:43 +00006289- Issue #1521: On 64bit platforms, using PyArgs_ParseTuple with the t#
6290 of w# format code incorrectly truncated the length to an int, even
6291 when PY_SSIZE_T_CLEAN is set. The str.decode method used to return
6292 incorrect results with huge strings.
Georg Brandl6caad7d2008-01-26 14:19:22 +00006293
Georg Brandl3ee81df2008-05-17 18:14:43 +00006294- Issue #1629: Renamed Py_Size, Py_Type and Py_Refcnt to Py_SIZE,

6311
6312- Fix some leftovers from the conversion from int to Py_ssize_t
6313 (relevant to strings and sequences of more than 2**31 items).
6314
6315- Make _PyGILState_NoteThreadState() static, it was not used anywhere
6316 outside of pystate.c and should not be necessary.
6317
Georg Brandl3ee81df2008-05-17 18:14:43 +00006318- ``PyImport_Import`` and ``PyImport_ImportModule`` now always do
6319 absolute imports. In earlier versions they might have used relative
6320 imports under some conditions.
Christian Heimes000a0742008-01-03 22:16:32 +00006321
Georg Brandl3ee81df2008-05-17 18:14:43 +00006322- Added case insensitive comparison methods ``PyOS_stricmp(char*,
6323 char*)`` and ``PyOS_strnicmp(char*, char*, Py_ssize_t)``.
Christian Heimes000a0742008-01-03 22:16:32 +00006324
Georg Brandl3ee81df2008-05-17 18:14:43 +00006325- Bug #1542693: remove semi-colon at end of PyImport_ImportModuleEx

Georg Brandl3ee81df2008-05-17 18:14:43 +00006332- Patch #1706: Drop support for Win9x, WinME and NT4. Python now
6333 requires Windows 2000 or greater. The _WINVER and NTDDI_VERSION
6334 macros are set to Win2k for x86/32bit builds and WinXP for AMD64
6335 builds.
Christian Heimes95d64472008-02-09 19:55:22 +00006336

Georg Brandl3ee81df2008-05-17 18:14:43 +00006350- Removed the macfs module. It had been deprecated since Python 2.5.
6351 This lead to the deprecation of macostools.touched() as it relied
6352 solely on macfs and was a no-op under OS X.
