48 utf-16 incremental encoders.
49
Ezio Melotti86e5e172010-07-03 05:34:39 +000050- Issue #8271: during the decoding of an invalid UTF-8 byte sequence, only the
51 start byte and the continuation byte(s) are now considered invalid, instead
52 of the number of bytes specified by the start byte.
53 E.g.: '\xf1\x80AB'.decode('utf-8', 'replace') now returns u'\ufffdAB' and
54 replaces with U+FFFD only the start byte ('\xf1') and the continuation byte
55 ('\x80') even if '\xf1' is the start byte of a 4-bytes sequence.
56 Previous versions returned a single u'\ufffd'.

Mark Dickinsonb671c292010-06-05 12:15:35 +000065 __hash__ in 3.x" warning. Also fix "XXX undetected error" that
66 arises from the "Overriding __eq__ blocks inheritance ..." warning
67 when turned into an exception: in this case the exception simply
68 gets ignored.

Georg Brandl0ba1f012010-08-01 22:00:39 +000070- Issue #4108: In urllib.robotparser, if there are multiple 'User-agent: *'
71 entries, consider the first one.

85 it from another thread. Patch by Daniel Stutzbach.
86
Mark Dickinsone02c9d22010-05-07 13:23:18 +000087- Issue #1533: fix inconsistency in range function argument
88 processing: any non-float non-integer argument is now converted to
89 an integer (if possible) using its __int__ method. Previously, only
90 small arguments were treated this way; larger arguments (those whose
91 __int__ was outside the range of a C long) would produce a TypeError.
92
Barry Warsaw60537442010-08-03 22:39:42 +000093- Issue #8417: Raise an OverflowError when an integer larger than sys.maxsize

119 <http://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2008-5983>`_.

1253
Barry Warsaw90971e02009-04-07 01:54:02 +00001254- Issue #4034: Fix weird attribute error messages of the traceback object. (As
1255 a result traceback.__members__ no longer exists.)
Benjamin Peterson53f098c2009-03-18 21:49:29 +00001256
Eric Smith1718b472009-02-20 14:07:55 +00001257- Issue #5247: Improve error message when unknown format codes are

1266
Georg Brandl21896072010-08-01 22:31:28 +00001267- Issue #1242657: the __len__() and __length_hint__() calls in several tools
Raymond Hettinger24e28722009-02-02 22:44:06 +00001268 were suppressing all exceptions. These include list(), filter(), map(),

1273 the interpreter segfault instead of raising an error.
1274
Georg Brandl686d53e2009-01-14 00:08:09 +00001275- Issue #4915: Port sysmodule to Windows CE.

1281 Patch by Ziga Seilnacht and Jean-Paul Calderone.
1282
Georg Brandl734373c2009-01-03 21:55:17 +00001283- Issue #4075: Use OutputDebugStringW in Py_FatalError.

1293
Georg Brandl47fe9812009-01-01 15:46:10 +00001294- Issue #4764: With io.open, IOError.filename is set when trying to open a
1295 directory on POSIX systems.
1296
1297- Issue #4764: IOError.filename is set when trying to open a directory on POSIX
1298 systems.

1306 fail.
1307
Jeffrey Yasskin69614982008-12-11 05:21:18 +00001308- Issue #4597: Fixed several opcodes that weren't always propagating

1310
Benjamin Petersonc6e80eb2008-12-21 17:01:26 +00001311- Issue #2467: gc.DEBUG_STATS reported invalid elapsed times. Also, always

Amaury Forgeot d'Arc79c9f762008-12-10 23:56:33 +00001316 context manager returns a value that cannot be converted to a bool.
1317
Vinay Sajip6badbe92009-01-20 22:49:13 +00001318- Issue #4233: Changed semantic of ``_fileio.FileIO``'s ``close()``
Georg Brandld2094602008-12-05 08:51:30 +00001319 method on file objects with closefd=False. The file descriptor is still
1320 kept open but the file object behaves like a closed file. The ``FileIO``
1321 object also got a new readonly attribute ``closefd``.
1322
Georg Brandlfa71a902008-12-05 09:08:28 +00001323- Issue #3689: The list reversed iterator now supports __length_hint__

1354- Issue #4572: added SEEK_* symbolic constants to io module.
1355
1356- Issue #1665206 (partially): Move imports in cgitb to the top of the module

Jesse Nollerb48cfa62009-03-30 16:19:10 +00001391 socket.SO_REUSEADDR on all connections so that the user no longer needs

1393
1394- Adjusted _tkinter to compile without warnings when WITH_THREAD is not
1395 defined (part of issue #5035).

1404 partial bzip2 compressed data.
1405
Benjamin Peterson373498f2009-03-22 17:49:21 +00001406- Issue #5536: urllib.urlretrieve makes sure to close the file it's writing to

Antoine Pitrou19fec8b2009-01-21 00:56:37 +00001495- Issue #5008: When a file is opened in append mode with the new IO library,
1496 do an explicit seek to the end of file (so that e.g. tell() returns the

1498 traditional 2.x file object.

1694What's New in Python 2.6.1
1695==========================
1696
1697*Release date: 04-Dec-2008*
1698
1699Core and Builtins
1700-----------------
1701
1702- Issue #3996: On Windows, the PyOS_CheckStack function would cause the
1703 interpreter to abort ("Fatal Python error: Could not reset the stack!")
1704 instead of throwing a MemoryError.
1705
1706- Issue #4367: Python would segfault during compiling when the unicodedata
1707 module couldn't be imported and \N escapes were present.
1708
1709- Issue #4348: Some bytearray methods returned that didn't cause any change to
1710 the bytearray, returned the same bytearray instead of a copy.
1711
1712- Issue #4317: Fixed a crash in the imageop.rgb2rgb8() function.
1713
1714- Issue #4230: If ``__getattr__`` is a descriptor, it now functions correctly.
1715
1716- Issue #4048: The parser module now correctly validates relative imports.
1717
1718- Issue #4225: ``from __future__ import unicode_literals`` didn't work in an
1719 exec statement.
1720
1721- Issue #4176: Fixed a crash when pickling an object which ``__reduce__``
1722 method does not return iterators for the 4th and 5th items.
1723
1724- Issue #4209: Enabling unicode_literals and the print_function in the same
1725 __future__ import didn't work.
1726
1727- On windows, os.chdir given unicode was not working if GetCurrentDirectoryW
1728 returned a path longer than MAX_PATH. (But It's doubtful this code path is
1729 really executed because I cannot move to such directory on win2k)
1730
1731- Issue #4069: When set.remove(element) is used with a set element, the element
1732 is temporarily replaced with an equivalent frozenset. But the eventual
1733 KeyError would always report the empty frozenset([]) as the missing key. Now
1734 it correctly refers to the initial element.
1735
1736- Fixed C99 style comments in several files. Python is now C89 compatible
1737 again.

1865 AttributeError instead of RuntimeError, depending in which C API call
1866 exactly the recursion limit is exceeded. Consequently, both exception types
1867 are caught and silenced.

1883
Martin v. Löwis9fa5a282008-09-11 06:53:30 +00001884- Issue #3642: Suppress warning in obmalloc when size_t is larger than uint.
1885
Amaury Forgeot d'Arc05e34492008-09-10 22:04:45 +00001886- Issue #3743: In a few places, PY_FORMAT_SIZE_T was incorrectly used with
1887 PyString_FromFormat or PyErr_Format to display size_t values. The macro
1888 PY_FORMAT_SIZE_T is designed to select the correct format for the OS
1889 ``printf`` function, whereas PyString_FromFormat has an independent
1890 implementation and uses "%zd" on all platforms for size_t values.
1891 This makes a difference on win64, where ``printf`` needs "%Id" to display
1892 64bit values.
1893
Benjamin Peterson97179b02008-09-09 20:55:01 +00001894- Issue #3634: _weakref.ref(Exception).__init__() gave invalid return value on
1895 error.
1896
Amaury Forgeot d'Arcd3ffb892008-09-09 07:24:30 +00001897- Issue #3777: long() applied to a float object now always return a long
1898 object; previously an int would be returned for small values. the __long__
1899 method is allowed to return either an int or a long, but the behaviour of
1900 float objects should not change to respect backward compatibility.
1901
Amaury Forgeot d'Arc3571fbf2008-09-01 19:52:00 +00001902- Issue #3751: str.rpartition would perform a left-partition when called with
1903 a unicode argument.
1904
Benjamin Peterson17f03ca2008-09-01 14:18:30 +00001905- Issue #3683: Fix compilation when --without-threads is given.
1906
Antoine Pitroud4ae97b2008-08-29 18:39:48 +00001907- Issue #3668: Fix a memory leak with the "s*" argument parser in
Vinay Sajip35e3b032008-09-01 14:33:59 +00001908 PyArg_ParseTuple and friends, which occurred when the argument for "s*"
Antoine Pitroud4ae97b2008-08-29 18:39:48 +00001909 was correctly parsed but parsing of subsequent arguments failed.
1910
Vinay Sajip35e3b032008-09-01 14:33:59 +00001911- Issue #2534: speed up isinstance() and issubclass() by 50-70%, so as to
Antoine Pitrou0668c622008-08-26 22:42:08 +00001912 match Python 2.5 speed despite the __instancecheck__ / __subclasscheck__
1913 mechanism. In the process, fix a bug where isinstance() and issubclass(),
1914 when given a tuple of classes as second argument, were looking up
1915 __instancecheck__ / __subclasscheck__ on the tuple rather than on each
1916 type object.
1917
Neal Norwitz18aa3882008-08-24 05:04:52 +00001918- Fix crashes on memory allocation failure found with failmalloc.
1919
1920- Fix memory leaks found with valgrind and update suppressions file.
1921
1922- Fix compiler warnings in opt mode which would lead to invalid memory reads.
1923
1924- Fix problem using wrong name in decimal module reported by pychecker.
1925
Christian Heimes7d4c3172008-08-22 19:47:25 +00001926- Silenced another compiler warning about a used but not defined
1927 function 'stringlib_contains_obj'.
1928
Benjamin Peterson712ee922008-08-24 18:10:20 +00001929- Added warnings on the use of ``__getslice__``, ``__setslice__``, or
1930 ``__delslice__``.
1931
Gregory P. Smith2bb25cc2008-09-02 05:29:51 +00001932- Issue #3678: Correctly pass LDFLAGS and LDLAST to the linker on shared
1933 library targets in the Makefile.
1934
Gregory P. Smith980b99b2008-09-07 05:15:18 +00001935- Issue #1204: The configure script now tests for additional libraries
1936 that may be required when linking against readline. This fixes issues
1937 with x86_64 builds on some platforms (a few Linux flavors and OpenBSD).

1959
Nick Coghland2e09382008-09-11 12:11:06 +00001960- Issue #3781: Clean up the API for warnings.catch_warnings() by having it
Brett Cannon672237d2008-09-09 00:49:16 +00001961 return a list or None rather than a custom object.
1962
Benjamin Peterson6ac7d7c2008-09-06 19:28:11 +00001963- Issue #1638033: Cookie.Morsel gained the httponly attribute.

Brett Cannon1eaf0742008-09-02 01:25:16 +00001987 warnings.catch_warnings() along with some API cleanup. Expanding the tests
1988 for catch_warnings() also led to an improvement in the raising of a
1989 DeprecationWarning related to warnings.warn_explicit().
1990
Benjamin Peterson973e6c22008-09-01 23:12:58 +00001991- The deprecation warnings for the old camelCase threading API were removed.

2010
Amaury Forgeot d'Arc293924b2008-09-02 23:19:56 +00002011- Issue #2975: When compiling several extension modules with Visual Studio 2008
2012 from the same python interpreter, some environment variables would grow
2013 without limit.
2014
Benjamin Peterson37346b22008-08-23 20:27:43 +00002015- Issue #3643: Added a few more checks to _testcapi to prevent segfaults by
2016 exploitation of poor argument checking.

Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00002052What's New in Python 2.6 beta 3?
2053================================
2054
Barry Warsaw07a4a382008-08-21 01:15:08 +00002055*Release date: 20-Aug-2008*
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00002056
2057Core and Builtins
2058-----------------
2059
Guido van Rossumf8402962008-08-20 15:01:50 +00002060- Issue #1878: Remove Py_TPFLAGS_HAVE_VERSION_TAG from
2061 Py_TPFLAGS_DEFAULT when not building the core. This means 3rd party
2062 extensions do not automatically benefit from the class attribute
2063 cache; they will have to explicitly add Py_TPFLAGS_HAVE_VERSION_TAG
2064 to their tp_flags field if they care. This is a backwards
2065 compatibility feature; in 3.0, all types will use the cache by
2066 default.
2067
Benjamin Petersonf647dc12008-08-20 01:27:30 +00002068- Keyword arguments can now follow starred arguments. (``f(a, *args,
2069 keyword=23)`` is now valid syntax.)
2070
Thomas Heller0ad5ae02008-08-19 19:25:04 +00002071- ctypes function pointers that are COM methods have a boolean True
2072 value again.
2073
Martin v. Löwisf91d46a2008-08-12 14:49:50 +00002074- Issue #3139: Make buffer-interface thread-safe wrt. PyArg_ParseTuple,
2075 by denying s# to parse objects that have a releasebuffer procedure,
2076 and introducing s*.
2077
Georg Brandl1e13ea92008-08-11 09:07:59 +00002078- Issue #3537: Fix an assertion failure when an empty but presized dict
2079 object was stored in the freelist.
2080
Mark Dickinsonb6467572008-08-04 21:30:09 +00002081- Issue #1481296: Make long(float('nan')) and int(float('nan')) raise
2082 ValueError consistently across platforms.
2083
Amaury Forgeot d'Arc39fd6722008-07-31 21:28:03 +00002084- Issue #3479: On platforms where sizeof(int) is smaller than sizeof(long)
2085 (64bit Unix, for example), unichr() would truncate its argument and return
2086 u'\x00' for unichr(2**32). Now it properly raises an OverflowError.
2087
Neal Norwitze7d8be82008-07-31 17:17:14 +00002088- Apply security patches from Apple.
2089
Amaury Forgeot d'Arc246daed2008-07-31 00:42:16 +00002090- Issue #2542: Now that issubclass() may call arbitrary code, ensure that
2091 PyErr_ExceptionMatches returns 0 when an exception occurs there.
2092
Antoine Pitrou92f82162008-07-25 22:22:08 +00002093- Issue #1819: function calls with several named parameters are now on
2094 average 35% faster (as measured by pybench).
2095
Amaury Forgeot d'Arce4921fe2008-07-21 22:00:38 +00002096- Issue #2378: An unexpected UnboundLocalError or NameError could appear when
2097 the python debugger steps into a class statement: the free variables (local
2098 variables defined in an outer scope) would be deleted from the outer scope.
2099
Gregory P. Smith0470bab2008-07-22 04:46:32 +00002100- Issue #2620: Overflow checking when allocating or reallocating memory
2101 was not always being done properly in some python types and extension
2102 modules. PyMem_MALLOC, PyMem_REALLOC, PyMem_NEW and PyMem_RESIZE have
2103 all been updated to perform better checks and places in the code that
2104 would previously leak memory on the error path when such an allocation
2105 failed have been fixed.

2113 symtable.Symbol have been deprecated for removal in 3.0 and the next release.
2114
Amaury Forgeot d'Arc351ffb82008-08-18 19:23:47 +00002115- Issue #2234: distutils failed for some versions of the cygwin compiler. The
2116 version reported by these tools does not necessarily follow the python
2117 version numbering scheme, so the module is less strict when parsing it.
2118
Nick Coghlanf70385a2008-08-18 12:42:46 +00002119- Issue #2235: Added Py3k warnings for types which will become unhashable
2120 under the stricter __hash__ inheritance rules in 3.0. Several types
2121 which did not meet the rules for hash invariants and were already
2122 unhashable in 3.0 have now been explicitly flagged as unhashable in
2123 2.6 as well (collections.Mapping, collections.Set, unittest.TestSuite,
2124 xml.dom.minidom.NamedNodeMap, numbers.Number, UserList.UserList)
2125
Brett Cannon88f801d2008-08-18 00:46:22 +00002126- Update __all__ for cookielib, csv, os, urllib2, and weakref to include things

2134
Hirokazu Yamamoto41a81eb2008-08-17 13:10:46 +00002135- Issue #3575: Incremental decoder's decode function now takes bytearray
2136 by using 's*' instead of 't#'.
2137
Jesus Cea585ad8a2009-07-02 15:37:21 +00002138- Issue #2222: Fixed reference leak when occurred os.rename()
Hirokazu Yamamoto7f30a682008-08-17 09:46:56 +00002139 fails unicode conversion on 2nd parameter. (windows only)
2140
Georg Brandl21896072010-08-01 22:31:28 +00002141- Issue #2464: urllib2 now supports a malformation in the URL received
Facundo Batista94f243a2008-08-17 03:38:39 +00002142 in a redirect.
2143

Brett Cannon721b1452008-08-16 22:00:27 +00002145 BaseHTTPServer, cgi (and rfc822), httplib.
Brett Cannonabe423e2008-08-16 21:47:07 +00002146
Facundo Batistaeb90b782008-08-16 14:44:07 +00002147- Issue #2776: fixed small issue when handling an URL with double slash
2148 after a 302 response in the case of not going through a proxy.
2149
Antoine Pitroub90a8be2008-08-15 21:03:21 +00002150- Issue #2676: in the email package, content-type parsing was hanging on
2151 pathological input because of quadratic or exponential behaviour of a
2152 regular expression.
2153
Antoine Pitrou11ec65d2008-08-14 21:04:30 +00002154- Issue #3476: binary buffered reading through the new "io" library is now

Antoine Pitroude781a42008-08-09 12:43:23 +00002195 asking for a specific length. This problem only affected files opened

2239
Nick Coghlan2a0c2b12008-08-04 12:47:17 +00002240- Issue #643841: The language reference now provides more detailed

2252-----------------
2253
Georg Brandl3e483f62008-07-16 22:57:41 +00002254- Issue #3156: Fix inconsistent behavior of the bytearray type: all
2255 its methods now allow for items objects that can be converted to
2256 an integer using operator.index().
2257
Mark Dickinson64b7e502008-07-16 09:40:03 +00002258- Issue #3360: Fix incorrect parsing of '020000000000.0', which
2259 produced a ValueError instead of giving the correct float.
2260
Eric Smitha5fa5a22008-07-16 00:11:49 +00002261- Issue #3083: Add alternate (#) formatting for bin, oct, hex output
2262 for str.format(). This adds the prefix 0b, 0o, or 0x, respectively.
2263
Mark Dickinson7103aa42008-07-15 19:08:33 +00002264- Issue #3008: the float type has a new instance method 'float.hex'
2265 and a new class method 'float.fromhex' to convert floating-point
2266 numbers to and from hexadecimal strings, respectively.
2267
Nick Coghlan6d6bd442008-07-15 15:40:22 +00002268- Issue #2235: __hash__ is once again inherited by default. To allow
2269 collections.Hashable to remain meaningful in the presence of the
2270 default hash implementation (object.__hash__), it is now possible
2271 to explicit block inheritance of hash by setting __hash__=None at
2272 the Python level, or tp_hash=PyObject_HashNotImplemented at the C
2273 level.
2274
Nick Coghlanb028f502008-07-13 14:52:36 +00002275- Issue #3221: Issue a RuntimeWarning instead of raising SystemError if
2276 the parent module cannot be found while performing an absolute import.
2277 This means that an incorrectly defined __package__ attribute will
2278 now only prevent relative imports in that module rather than causing
2279 all imports from that module to fail.
2280
Nick Coghlan14ff9942008-07-08 14:21:42 +00002281- Issue #2517: Allow unicode messages in Exceptions again by correctly

2291 another thread's dictionary.
2292
Mark Dickinson1ec2fcd2008-06-20 14:53:43 +00002293- Issue #3004: Minor change to slice.indices(): the start and stop
2294 arguments are now treated identically, making the behaviour easier
2295 to describe and understand. For example, slice(None, -10,
2296 1).indices(9) now returns (0, 0, 1) instead of (0, -1, 1), and
2297 slice(None, 10, -1).indices(10) returns (9, 9, -1) instead of (9,
2298 10, -1).
2299
Georg Brandl278fc502008-07-19 12:46:12 +00002300- Issue #3219: Calling a function with repeated keyword arguments,
2301 f(a=2, a=23), would not cause a syntax error. This was a regression
2302 from 2.4 caused by the switch to the new compiler.

Georg Brandl278fc502008-07-19 12:46:12 +00002304- Issue #2862: Make int and float freelist management consistent with
2305 other freelists. Changes their CompactFreeList apis into

Amaury Forgeot d'Arc0f7cddc2008-07-06 21:34:39 +00002340- Issue #839496: SimpleHTTPServer used to open text files in text mode. This is
2341 both unnecessary (HTTP allows text content to be sent in several forms) and
Andrew M. Kuchlingcc3f2b12008-07-10 14:43:31 +00002342 wrong because the actual transmitted size could differ from the
Amaury Forgeot d'Arc0f7cddc2008-07-06 21:34:39 +00002343 content-length. The problem had been corrected in the 2.4 branch, but never

Nick Coghlanc060b0e2008-07-02 13:09:19 +00002359- Issue #3190: Pydoc now hides the automatic module attribute __package__ (the

Benjamin Peterson23681932008-05-12 21:42:13 +00002729
Vinay Sajip9828b7e2008-06-17 11:04:02 +00002730- Library: on MacOS X you can now set ``ARCHFLAGS`` in the shell
Ronald Oussoren5640ce22008-06-05 12:58:24 +00002731 environment to control the '-arch' flags that are used to build
2732 an extension. This was added for compatibility with Apple's build
2733 of Python.
2734
2735- The bundled OSX-specific copy of libbffi is now in sync with the version
2736 shipped with PyObjC 2.0 and includes support for x86_64 and ppc64 platforms.
2737
Georg Brandl25c34082008-08-18 23:09:49 +00002738- The threading module gained aliases for names that will be removed in the

2747
Brett Cannonb61d8012008-05-11 23:39:04 +00002748- ``Lib/lib-old`` is now added to sys.path.
2749
Ronald Oussoren5640ce22008-06-05 12:58:24 +00002750- On MacOS X it is now possible to install the framework in 64-bit
2751 mode or even as a 4-way universal binary (that is, PPC, i386,
Georg Brandl5cc774e2008-06-11 20:28:06 +00002752 PPC64 and x86_64 support in one binary).
Ronald Oussoren5640ce22008-06-05 12:58:24 +00002753
2754 This is controlled by the configure argument ``--with-universal-archs``:
2755
2756 - ``--with-universal-archs=all``: install 4-way universal
2757
2758 - ``--with-universal-archs=32-bit``: install 2-way universal, 32-bit (the default)
2759
2760 - ``--with-universal-archs=64-bit``: install 2-way universal, 64-bit
2761
2762 This option should be used in combination with ``--enable-universalsdk=``.
2763
2764 NOTE: 64-bit and 4-way builds are only suppported on Mac OS X 10.5 (or later).

Georg Brandl3ee81df2008-05-17 18:14:43 +00002814- Issue #1631171: Re-implement the 'warnings' module in C (the
2815 original Python code has been kept as backup). This will allow for
2816 using the 'warning's machinery in such places as the parser where
2817 use of pure Python code is not possible. Both the ``showarning()``
2818 and ``formatwarning()`` gain an optional 'line' argument which is
2819 not called by default for backwards-compatibility reasons. Setting
2820 ``warnings.showwarning()`` to an implementation that lacks support
2821 for the ``line`` argument will raise a DeprecationWarning.

2845
Gregory P. Smithd59fefb2008-04-22 08:11:33 +00002846- The getpass module has been improved on Unix. It now uses /dev/tty
2847 by default and uses stderr instead of stdout. A GetPassWarning is
2848 issued when input echo cannot be controlled.
Gregory P. Smith41e30182008-04-21 21:31:08 +00002849

Georg Brandl3ee81df2008-05-17 18:14:43 +00002863- Issue #2513: distutils on Windows is now capable of cross-compiling
Mark Hammond495cf992008-04-07 01:53:39 +00002864 extension modules between 32 and 64 bit platforms. See the distutls

Georg Brandl3ee81df2008-05-17 18:14:43 +00002884- Issue #2550: The approach used by client/server code for obtaining
2885 ports to listen on in network-oriented tests has been refined in an
2886 effort to facilitate running multiple instances of the entire
2887 regression test suite in parallel without issue.
2888 test_support.bind_port() has been fixed such that it will always
2889 return a unique port -- which wasn't always the case with the
2890 previous implementation, especially if socket options had been set
2891 that affected address reuse (i.e. SO_REUSEADDR, SO_REUSEPORT). The
2892 new implementation of bind_port() will actually raise an exception
2893 if it is passed an AF_INET/SOCK_STREAM socket with either the
2894 SO_REUSEADDR or SO_REUSEPORT socket option set. Furthermore, if
2895 available, bind_port() will set the SO_EXCLUSIVEADDRUSE option on
2896 the socket it's been passed. This currently only applies to
2897 Windows. This option prevents any other sockets from binding to the
2898 host/port we've bound to, thus removing the possibility of the
2899 'non-deterministic' behaviour, as Microsoft puts it, that occurs
2900 when a second SOCK_STREAM socket binds and accepts to a host/port
2901 that's already been bound by another socket. The optional preferred
2902 port parameter to bind_port() has been removed. Under no
2903 circumstances should tests be hard coding ports!
2904
2905 test_support.find_unused_port() has also been introduced, which will
2906 pass a temporary socket object to bind_port() in order to obtain an
2907 unused port. The temporary socket object is then closed and
2908 deleted, and the port is returned. This method should only be used
2909 for obtaining an unused port in order to pass to an external program
2910 (i.e. the -accept [port] argument to openssl's s_server mode) or as
2911 a parameter to a server-oriented class that doesn't give you direct
2912 access to the underlying socket used.
2913
2914 Finally, test_support.HOST has been introduced, which should be used
2915 for the host argument of any relevant socket calls (i.e. bind and
2916 connect).
Trent Nelsone41b0062008-04-08 23:47:30 +00002917
2918 The following tests were updated to following the new conventions:
Georg Brandl3ee81df2008-05-17 18:14:43 +00002919 test_socket, test_smtplib, test_asyncore, test_ssl, test_httplib,
Trent Nelsone41b0062008-04-08 23:47:30 +00002920 test_poplib, test_ftplib, test_telnetlib, test_socketserver,
2921 test_asynchat and test_socket_ssl.
2922
Georg Brandl3ee81df2008-05-17 18:14:43 +00002923 It is now possible for multiple instances of the regression test
2924 suite to run in parallel without issue.

Eric Smitha73fbe72008-02-23 03:09:44 +00003203- Added the future_builtins module, which contains hex() and oct().
3204 These are the PEP 3127 version of these functions, designed to be
3205 compatible with the hex() and oct() builtins from Python 3.0. They
3206 differ slightly in their output formats from the existing, unchanged
3207 Python 2.6 builtins. The expected usage of the future_builtins
3208 module is:
3209 from future_builtins import hex, oct
3210
Eric Smith7ef40bf2008-02-20 23:34:22 +00003211- Issue #1600: Modifed PyOS_ascii_formatd to use at most 2 digit
3212 exponents for exponents with absolute value < 100. Follows C99
3213 standard. This is a change on Windows, which would use 3 digits.
3214 Also, added 'n' to the formats that PyOS_ascii_formatd understands,
3215 so that any alterations it does to the resulting string will be
3216 available in stringlib/formatter.h (for float.__format__).
3217
Eric Smith5a3c1352008-02-19 13:21:56 +00003218- Implemented PEP 3101, Advanced String Formatting. This adds a new
3219 builtin format(); a format() method for str and unicode; a
3220 __format__() method to object, str, unicode, int, long, float, and
3221 datetime; the class string.Formatter; and the C API
3222 PyObject_Format().
3223
Georg Brandl3ee81df2008-05-17 18:14:43 +00003224- Fixed several potential crashes, all caused by specially crafted
3225 __del__ methods exploiting objects in temporarily inconsistent
3226 state.

3230 a slot on a registered virtual subclass.

3233 real or imaginary part.

3236 in order to allow pymalloc to free more arenas. Python may give back
3237 memory to the OS earlier.
Christian Heimes3b718a72008-02-14 12:47:33 +00003238
Georg Brandl3ee81df2008-05-17 18:14:43 +00003239- Issue #2045: Fix an infinite recursion triggered when printing a
3240 subclass of collections.defaultdict, if its default_factory is set
3241 to a bound method.
Amaury Forgeot d'Arcb01aa432008-02-08 00:56:02 +00003242
Christian Heimesf75dbef2008-02-08 00:11:31 +00003243- Fixed a minor memory leak in dictobject.c. The content of the free
3244 list was not freed on interpreter shutdown.

Georg Brandl5a7eca12010-03-21 19:29:04 +00003246- Limit free list of method and built-in function objects to 256
Georg Brandl3ee81df2008-05-17 18:14:43 +00003247 entries each.
Christian Heimes6075a822008-02-06 12:44:34 +00003248
Georg Brandl3ee81df2008-05-17 18:14:43 +00003249- Patch #1953: Added ``sys._compact_freelists()`` and the C API
3250 functions ``PyInt_CompactFreeList`` and ``PyFloat_CompactFreeList``
Christian Heimes422051a2008-02-04 18:00:12 +00003251 to compact the internal free lists of pre-allocted ints and floats.
3252
Georg Brandl3ee81df2008-05-17 18:14:43 +00003253- Issue #1983: Fixed return type of fork(), fork1() and forkpty()
3254 calls. Python expected the return type int but the fork familie
3255 returns pi_t.
Christian Heimes951cc0f2008-01-31 23:08:23 +00003256
Georg Brandl3ee81df2008-05-17 18:14:43 +00003257- Issue #1678380: Fix a bug that identifies 0j and -0j when they
3258 appear in the same code unit.
Mark Dickinson105be772008-01-31 22:17:37 +00003259
Georg Brandl3ee81df2008-05-17 18:14:43 +00003260- Issue #2025: Add tuple.count() and tuple.index() methods to comply
3261 with the collections.Sequence API.
Raymond Hettinger5b07ebc2008-02-07 00:54:20 +00003262
Georg Brandl3ee81df2008-05-17 18:14:43 +00003263- Patch #1970 by Antoine Pitrou: Speedup unicode whitespace and
3264 linebreak detection
Christian Heimes4d4f2702008-01-30 11:32:37 +00003265
Georg Brandl3ee81df2008-05-17 18:14:43 +00003266- Added ``PyType_ClearCache()`` and ``sys._clear_type_cache`` to clear
3267 the internal lookup cache for ref leak tests.
Christian Heimes908caac2008-01-27 23:34:59 +00003268
Georg Brandl3ee81df2008-05-17 18:14:43 +00003269- Patch #1473257: generator objects gain a gi_code attribute. This is
3270 the same object as the func_code attribute of the function that
3271 produced the generator.
Georg Brandl0cdf9a32008-01-26 14:14:20 +00003272
Georg Brandl3ee81df2008-05-17 18:14:43 +00003273- Issue #1920: "while 0" statements were completely removed by the
3274 compiler, even in the presence of an "else" clause, which is
3275 supposed to be run when the condition is false. Now the compiler
3276 correctly emits bytecode for the "else" suite.
Amaury Forgeot d'Arc31eaafe2008-01-24 22:59:25 +00003277
Guido van Rossumeead05f2008-01-24 18:21:02 +00003278- A few crashers fixed: weakref_in_del.py (issue #1377858);
3279 loosing_dict_ref.py (issue #1303614, test67.py);
3280 borrowed_ref_[34].py (not in tracker).
3281
Vinay Sajipd7cf32e2008-01-24 12:43:33 +00003282- Issue #1069410: The "can't load dll" message box on Windows is
Christian Heimesb2302ba2008-01-23 17:15:06 +00003283 suppressed while an extension is loaded by calling SetErrorMode in
3284 dynload_win.c. The error is still reported properly.
3285
Georg Brandl3ee81df2008-05-17 18:14:43 +00003286- Issue #1915: Python compiles with --enable-unicode=no again. However
Christian Heimes082c9b02008-01-23 14:20:50 +00003287 several extension methods and modules do not work without unicode
3288 support.
3289
Georg Brandl26543b12008-01-21 18:36:51 +00003290- Issue #1882: when compiling code from a string, encoding cookies in the
3291 second line of code were not always recognized correctly.
3292
Georg Brandl14404b62008-01-19 19:27:05 +00003293- Issue #1679: "0x" was taken as a valid integer literal.
3294
Georg Brandl6caad7d2008-01-26 14:19:22 +00003295- Issue #1865: ``bytes`` as an alias for ``str`` and b"" as an alias "" were
Christian Heimes288e89a2008-01-18 18:24:07 +00003296 added.
3297
Christian Heimesc94e2b52008-01-14 04:13:37 +00003298- sys.float_info / PyFloat_GetInfo: The floating point information
3299 object was converted from a dict to a specialized structseq object.
3300
Georg Brandl3ee81df2008-05-17 18:14:43 +00003301- Patch #1816: Added sys.flags structseq. It exposes the status of
3302 most command line arguments and PYTHON* environment variables.
Christian Heimesf31b69f2008-01-14 03:42:48 +00003303
Georg Brandl3ee81df2008-05-17 18:14:43 +00003304- Objects/structseq.c: Implemented new structseq representation. The
3305 patch makes structseqs (e.g. the return value of os.stat) more
3306 readable.
Christian Heimes9c201962008-01-14 03:33:52 +00003307
Georg Brandl3ee81df2008-05-17 18:14:43 +00003308- Patch #1700288: added a type attribute cache that caches method
3309 accesses, resulting in speedups in heavily object-oriented code.
Amaury Forgeot d'Arce4c270c2008-01-14 00:29:41 +00003310
Neal Norwitz3fc15b82008-01-10 05:42:58 +00003311- Bug #1776: __import__() no longer accepts filenames on any platform.
3312 The first parameter to __import__() must be a valid module name.
Christian Heimes3403f152008-01-09 19:56:33 +00003313
Georg Brandlaed6c662008-01-07 17:25:53 +00003314- Patch #1668: renamed THREADDEBUG envvar to PYTHONTHREADDEBUG.
3315
Georg Brandl3ee81df2008-05-17 18:14:43 +00003316- Patch #602345: Add -B command line option, PYTHONDONTWRITEBYTECODE
3317 envvar and sys.dont_write_bytecode attribute. All these can be set
3318 to forbid Python to attempt to write compiled bytecode files.
Georg Brandl2da0fce2008-01-07 17:09:35 +00003319
Georg Brandl3ee81df2008-05-17 18:14:43 +00003320- Improve some exception messages when Windows fails to load an
3321 extension module. Now we get for example '%1 is not a valid Win32
3322 application' instead of 'error code 193'.
Amaury Forgeot d'Arce0b76952008-01-04 02:04:15 +00003323
Georg Brandl3ee81df2008-05-17 18:14:43 +00003324- Bug #1481296: Fixed long(float('nan')) != 0L.

Georg Brandl3ee81df2008-05-17 18:14:43 +00003326- Issue #1640: Added math.isinf(x), math.isnan(x) and math.copysign(x,
3327 y) functions.
Christian Heimese2ca4242008-01-03 20:23:15 +00003328
Christian Heimes0a8143f2007-12-18 23:22:54 +00003329- Issue #1635: Platform independent creation and representation of NaN
Georg Brandl3ee81df2008-05-17 18:14:43 +00003330 and INF. float("nan"), float("inf") and float("-inf") now work on
3331 every platform with IEEE 754 semantics.
Christian Heimes0a8143f2007-12-18 23:22:54 +00003332
Georg Brandl3ee81df2008-05-17 18:14:43 +00003333- Compiler now generates simpler and faster code for dictionary
3334 literals. The oparg for BUILD_MAP now indicates an estimated
3335 dictionary size. There is a new opcode, STORE_MAP, for adding
3336 entries to the dictionary.
Raymond Hettingerfd7ed402007-12-18 21:24:09 +00003337
Georg Brandl3ee81df2008-05-17 18:14:43 +00003338- Issue #1638: %zd configure test fails on Linux.
Christian Heimesdb3d6cb2007-12-16 21:39:43 +00003339
Georg Brandl3ee81df2008-05-17 18:14:43 +00003340- Issue #1620: New property decorator syntax was modifying the
3341 decorator in place instead of creating a new decorator object.

Georg Brandl3ee81df2008-05-17 18:14:43 +00003343- Issue #1538: Avoid copying string in split/rsplit if the split char
3344 is not found.
Skip Montanaro26015492007-12-08 15:33:24 +00003345
Andrew M. Kuchling395fe442007-12-05 13:27:20 +00003346- Issue #1553: An erroneous __length_hint__ can make list() raise a
Christian Heimes7cc1c6f2007-12-05 12:52:34 +00003347 SystemError.
3348
Nick Coghlanef01d822007-12-03 12:55:17 +00003349- PEP 366: Allow explicit relative imports when executing modules

Georg Brandl3ee81df2008-05-17 18:14:43 +00003365- Patch #1739468: Directories and zipfiles containing a __main__.py
3366 file can now be directly executed by passing their name to the
3367 interpreter. The directory/zipfile is automatically inserted as the
3368 first entry in sys.path.
Nick Coghlan327a39b2007-11-18 11:56:28 +00003369
Georg Brandl3ee81df2008-05-17 18:14:43 +00003370- Issue #1265: Fix a problem with sys.settrace, if the tracing
3371 function uses a generator expression when at the same time the
3372 executed code is closing a paused generator.
Amaury Forgeot d'Arc0d75f092007-11-13 21:54:28 +00003373
Raymond Hettinger1760c8a2007-11-08 02:52:43 +00003374- sets and frozensets now have an isdisjoint() method.
3375
Raymond Hettinger3f8caa32007-10-24 01:28:33 +00003376- optimize the performance of builtin.sum().
3377
Neal Norwitz44f326e2007-10-05 05:29:17 +00003378- Fix warnings found by the new version of the Coverity checker.
3379
Georg Brandl5a7eca12010-03-21 19:29:04 +00003380- The enumerate() built-in function is no longer bounded to sequences
Georg Brandl3ee81df2008-05-17 18:14:43 +00003381 smaller than LONG_MAX. Formerly, it raised an OverflowError. Now,
3382 automatically shifts from ints to longs.
Raymond Hettinger8f669372007-10-03 21:18:11 +00003383
Georg Brandl3ee81df2008-05-17 18:14:43 +00003384- Issue #1686386: Tuple's tp_repr did not take into account the
3385 possibility of having a self-referential tuple, which is possible
3386 from C code. Nor did object's tp_str consider that a type's tp_str
3387 could do something that could lead to an inifinite recursion.
3388 Py_ReprEnter() and Py_EnterRecursiveCall(), respectively, fixed the
3389 issues.
Brett Cannon0b14f242007-09-30 19:45:10 +00003390
Georg Brandl3ee81df2008-05-17 18:14:43 +00003391- Issue #1164: It was possible to trigger deadlock when using the
3392 'print' statement to write to a file since the GIL was not released
3393 as needed. Now PyObject_Print() does the right thing along with
3394 various tp_print implementations of the built-in types and those in
3395 the collections module.
Brett Cannon01531592007-09-17 03:28:34 +00003396
Georg Brandl3ee81df2008-05-17 18:14:43 +00003397- Issue #1147: Exceptions were directly allowing string exceptions in
3398 their throw() method even though string exceptions no longer
3399 allowed.
Brett Cannon4c20bc42007-09-11 21:02:28 +00003400
Georg Brandl3ee81df2008-05-17 18:14:43 +00003401- Issue #1096: Prevent a segfault from getting the repr of a very
3402 deeply nested list by using the recursion counter.
Brett Cannona0c05512007-09-10 21:38:27 +00003403
Brett Cannon1e534b52007-09-07 04:18:30 +00003404- Issue #1202533: Fix infinite recursion calls triggered by calls to
Georg Brandl3ee81df2008-05-17 18:14:43 +00003405 PyObject_Call() never calling back out to Python code to trigger
3406 recursion depth updates/checks. Required the creation of a static
3407 RuntimeError instance in case normalizing an exception put the
3408 recursion check value past its limit. Fixes crashers
3409 infinite_rec_(1|2|4|5).py.
Brett Cannon1e534b52007-09-07 04:18:30 +00003410
Georg Brandl3ee81df2008-05-17 18:14:43 +00003411- Patch #1031213: Decode source line in SyntaxErrors back to its

Neal Norwitz0ac60192007-05-27 04:08:54 +00003424- Add new attribute names for function objects. All the func_* become
Georg Brandl3ee81df2008-05-17 18:14:43 +00003425 __*__ attributes. (Some already existed, e.g., __doc__ and
3426 __name__.)
Neal Norwitz0ac60192007-05-27 04:08:54 +00003427
Neal Norwitz8b2bfbc2007-05-23 06:35:32 +00003428- Add -3 option to the interpreter to warn about features that are
3429 deprecated and will be changed/removed in Python 3.0.
3430
Georg Brandl2134e752007-05-21 20:34:16 +00003431- Patch #1686487: you can now pass any mapping after '**' in function
3432 calls.
3433
Collin Winter62903052007-05-18 23:11:24 +00003434- except clauses may now be spelled either "except E, target:" or
Georg Brandl3ee81df2008-05-17 18:14:43 +00003435 "except E as target:". This is to provide forwards compatibility
3436 with Python 3.0.
Collin Winter62903052007-05-18 23:11:24 +00003437
Brett Cannon229cee22007-05-05 01:34:02 +00003438- Deprecate BaseException.message as per PEP 352.
3439
Georg Brandl3ee81df2008-05-17 18:14:43 +00003440- Issue #1303614: don't expose object's __dict__ when the dict is
Georg Brandl5a7eca12010-03-21 19:29:04 +00003441 inherited from a built-in base.
Armin Rigo9790a272007-05-02 19:23:31 +00003442
Vinay Sajip8549ce32007-05-06 17:53:37 +00003443- When __slots__ are set to a unicode string, make it work the same as
Neal Norwitzcbd9ee62007-04-14 05:25:50 +00003444 setting a plain string, ie don't expand to single letter identifiers.
3445
Raymond Hettinger13936692007-04-11 18:40:58 +00003446- Request #1191699: Slices can now be pickled.
3447
Raymond Hettinger4db5fe92007-04-12 04:10:00 +00003448- Request #1193128: str.translate() now allows a None argument for
3449 translations that only remove characters without re-mapping the
3450 remaining characters.
3451
Georg Brandl5cb76c12007-03-21 09:00:39 +00003452- Patch #1682205: a TypeError while unpacking an iterable is no longer
3453 masked by a generic one with the message "unpack non-sequence".
3454
Neal Norwitzaa754b72007-03-21 06:39:48 +00003455- Remove unused file Python/fmod.c.
3456
Guido van Rossum143b5642007-03-23 04:58:42 +00003457- Bug #1683368: The object.__init__() and object.__new__() methods are
3458 now stricter in rejecting excess arguments. The only time when
3459 either allows excess arguments is when it is not overridden and the
3460 other one is. For backwards compatibility, when both are
3461 overridden, it is a deprecation warning (for now; maybe a Py3k
Guido van Rossum234b1ff2007-03-23 19:39:01 +00003462 warning later). Also, type.__init__() insists on the same signature
3463 as supported by type.__new__().
Guido van Rossum143b5642007-03-23 04:58:42 +00003464
Georg Brandl3ee81df2008-05-17 18:14:43 +00003465- Patch #1675423: PyComplex_AsCComplex() now tries to convert an
3466 object to complex using its __complex__() method before falling back
3467 to the __float__() method. Therefore, the functions in the cmath
3468 module now can operate on objects that define a __complex__()
3469 method.
Georg Brandl2b869942007-03-17 16:08:45 +00003470
Georg Brandl3ee81df2008-05-17 18:14:43 +00003471- Patch #1623563: allow __class__ assignment for classes with
3472 __slots__. The old and the new class are still required to have the
3473 same slot names.

Georg Brandl3ee81df2008-05-17 18:14:43 +00004543 time so that opening a database previously created with the DB_DUP
4544 or DB_DUPSORT flag set will keep the proper behavior on subsequent
4545 opens. Specifically: dictionary assignment to a DB object will
4546 replace all values for a given key when the database allows
4547 duplicate values. DB users should use DB.put(k, v) when they want
4548 to store duplicates; not DB[k] = v.

4557 behavior of quoting dots if they are the second character of any
4558 line.
