44
Ezio Melotti86e5e172010-07-03 05:34:39 +000045- Issue #8271: during the decoding of an invalid UTF-8 byte sequence, only the
46 start byte and the continuation byte(s) are now considered invalid, instead
47 of the number of bytes specified by the start byte.
48 E.g.: '\xf1\x80AB'.decode('utf-8', 'replace') now returns u'\ufffdAB' and
49 replaces with U+FFFD only the start byte ('\xf1') and the continuation byte
50 ('\x80') even if '\xf1' is the start byte of a 4-bytes sequence.
51 Previous versions returned a single u'\ufffd'.

Mark Dickinsonb671c292010-06-05 12:15:35 +000060 __hash__ in 3.x" warning. Also fix "XXX undetected error" that
61 arises from the "Overriding __eq__ blocks inheritance ..." warning
62 when turned into an exception: in this case the exception simply
63 gets ignored.

81
Mark Dickinsone02c9d22010-05-07 13:23:18 +000082- Issue #1533: fix inconsistency in range function argument
83 processing: any non-float non-integer argument is now converted to
84 an integer (if possible) using its __int__ method. Previously, only
85 small arguments were treated this way; larger arguments (those whose
86 __int__ was outside the range of a C long) would produce a TypeError.
87
Barry Warsaw60537442010-08-03 22:39:42 +000088- Issue #8417: Raise an OverflowError when an integer larger than sys.maxsize

1248
Barry Warsaw90971e02009-04-07 01:54:02 +00001249- Issue #4034: Fix weird attribute error messages of the traceback object. (As

Benjamin Peterson53f098c2009-03-18 21:49:29 +00001251
Eric Smith1718b472009-02-20 14:07:55 +00001252- Issue #5247: Improve error message when unknown format codes are

1269
Georg Brandl686d53e2009-01-14 00:08:09 +00001270- Issue #4915: Port sysmodule to Windows CE.

1273 an existing .py counterpart, override the co_filename attributes of all

1276 Patch by Ziga Seilnacht and Jean-Paul Calderone.
1277
Georg Brandl734373c2009-01-03 21:55:17 +00001278- Issue #4075: Use OutputDebugStringW in Py_FatalError.

1288
Georg Brandl47fe9812009-01-01 15:46:10 +00001289- Issue #4764: With io.open, IOError.filename is set when trying to open a

Vinay Sajip6badbe92009-01-20 22:49:13 +00001313- Issue #4233: Changed semantic of ``_fileio.FileIO``'s ``close()``
Georg Brandld2094602008-12-05 08:51:30 +00001314 method on file objects with closefd=False. The file descriptor is still
1315 kept open but the file object behaves like a closed file. The ``FileIO``
1316 object also got a new readonly attribute ``closefd``.
1317
Georg Brandlfa71a902008-12-05 09:08:28 +00001318- Issue #3689: The list reversed iterator now supports __length_hint__

1399 partial bzip2 compressed data.

1689What's New in Python 2.6.1
1690==========================
1691
1692*Release date: 04-Dec-2008*
1693
1694Core and Builtins
1695-----------------
1696
1697- Issue #3996: On Windows, the PyOS_CheckStack function would cause the
1698 interpreter to abort ("Fatal Python error: Could not reset the stack!")
1699 instead of throwing a MemoryError.
1700
1701- Issue #4367: Python would segfault during compiling when the unicodedata
1702 module couldn't be imported and \N escapes were present.
1703
1704- Issue #4348: Some bytearray methods returned that didn't cause any change to
1705 the bytearray, returned the same bytearray instead of a copy.
1706
1707- Issue #4317: Fixed a crash in the imageop.rgb2rgb8() function.
1708
1709- Issue #4230: If ``__getattr__`` is a descriptor, it now functions correctly.
1710
1711- Issue #4048: The parser module now correctly validates relative imports.
1712
1713- Issue #4225: ``from __future__ import unicode_literals`` didn't work in an
1714 exec statement.
1715
1716- Issue #4176: Fixed a crash when pickling an object which ``__reduce__``
1717 method does not return iterators for the 4th and 5th items.
1718
1719- Issue #4209: Enabling unicode_literals and the print_function in the same
1720 __future__ import didn't work.
1721
1722- On windows, os.chdir given unicode was not working if GetCurrentDirectoryW
1723 returned a path longer than MAX_PATH. (But It's doubtful this code path is
1724 really executed because I cannot move to such directory on win2k)
1725
1726- Issue #4069: When set.remove(element) is used with a set element, the element
1727 is temporarily replaced with an equivalent frozenset. But the eventual
1728 KeyError would always report the empty frozenset([]) as the missing key. Now
1729 it correctly refers to the initial element.
1730
1731- Fixed C99 style comments in several files. Python is now C89 compatible
1732 again.

1877-----------------
1878
Martin v. Löwis9fa5a282008-09-11 06:53:30 +00001879- Issue #3642: Suppress warning in obmalloc when size_t is larger than uint.
1880
Amaury Forgeot d'Arc05e34492008-09-10 22:04:45 +00001881- Issue #3743: In a few places, PY_FORMAT_SIZE_T was incorrectly used with
1882 PyString_FromFormat or PyErr_Format to display size_t values. The macro
1883 PY_FORMAT_SIZE_T is designed to select the correct format for the OS
1884 ``printf`` function, whereas PyString_FromFormat has an independent
1885 implementation and uses "%zd" on all platforms for size_t values.
1886 This makes a difference on win64, where ``printf`` needs "%Id" to display
1887 64bit values.
1888
Benjamin Peterson97179b02008-09-09 20:55:01 +00001889- Issue #3634: _weakref.ref(Exception).__init__() gave invalid return value on
1890 error.
1891
Amaury Forgeot d'Arcd3ffb892008-09-09 07:24:30 +00001892- Issue #3777: long() applied to a float object now always return a long
1893 object; previously an int would be returned for small values. the __long__
1894 method is allowed to return either an int or a long, but the behaviour of
1895 float objects should not change to respect backward compatibility.
1896
Amaury Forgeot d'Arc3571fbf2008-09-01 19:52:00 +00001897- Issue #3751: str.rpartition would perform a left-partition when called with
1898 a unicode argument.
1899
Benjamin Peterson17f03ca2008-09-01 14:18:30 +00001900- Issue #3683: Fix compilation when --without-threads is given.
1901
Antoine Pitroud4ae97b2008-08-29 18:39:48 +00001902- Issue #3668: Fix a memory leak with the "s*" argument parser in
Vinay Sajip35e3b032008-09-01 14:33:59 +00001903 PyArg_ParseTuple and friends, which occurred when the argument for "s*"
Antoine Pitroud4ae97b2008-08-29 18:39:48 +00001904 was correctly parsed but parsing of subsequent arguments failed.
1905
Vinay Sajip35e3b032008-09-01 14:33:59 +00001906- Issue #2534: speed up isinstance() and issubclass() by 50-70%, so as to
Antoine Pitrou0668c622008-08-26 22:42:08 +00001907 match Python 2.5 speed despite the __instancecheck__ / __subclasscheck__
1908 mechanism. In the process, fix a bug where isinstance() and issubclass(),
1909 when given a tuple of classes as second argument, were looking up
1910 __instancecheck__ / __subclasscheck__ on the tuple rather than on each
1911 type object.
1912
Neal Norwitz18aa3882008-08-24 05:04:52 +00001913- Fix crashes on memory allocation failure found with failmalloc.
1914
1915- Fix memory leaks found with valgrind and update suppressions file.
1916
1917- Fix compiler warnings in opt mode which would lead to invalid memory reads.
1918
1919- Fix problem using wrong name in decimal module reported by pychecker.
1920
Christian Heimes7d4c3172008-08-22 19:47:25 +00001921- Silenced another compiler warning about a used but not defined
1922 function 'stringlib_contains_obj'.
1923
Benjamin Peterson712ee922008-08-24 18:10:20 +00001924- Added warnings on the use of ``__getslice__``, ``__setslice__``, or
1925 ``__delslice__``.
1926
Gregory P. Smith2bb25cc2008-09-02 05:29:51 +00001927- Issue #3678: Correctly pass LDFLAGS and LDLAST to the linker on shared
1928 library targets in the Makefile.
1929
Gregory P. Smith980b99b2008-09-07 05:15:18 +00001930- Issue #1204: The configure script now tests for additional libraries
1931 that may be required when linking against readline. This fixes issues
1932 with x86_64 builds on some platforms (a few Linux flavors and OpenBSD).

1954
Nick Coghland2e09382008-09-11 12:11:06 +00001955- Issue #3781: Clean up the API for warnings.catch_warnings() by having it
Brett Cannon672237d2008-09-09 00:49:16 +00001956 return a list or None rather than a custom object.
1957
Benjamin Peterson6ac7d7c2008-09-06 19:28:11 +00001958- Issue #1638033: Cookie.Morsel gained the httponly attribute.

Brett Cannon1eaf0742008-09-02 01:25:16 +00001982 warnings.catch_warnings() along with some API cleanup. Expanding the tests
1983 for catch_warnings() also led to an improvement in the raising of a
1984 DeprecationWarning related to warnings.warn_explicit().
1985
Benjamin Peterson973e6c22008-09-01 23:12:58 +00001986- The deprecation warnings for the old camelCase threading API were removed.

2005
Amaury Forgeot d'Arc293924b2008-09-02 23:19:56 +00002006- Issue #2975: When compiling several extension modules with Visual Studio 2008
2007 from the same python interpreter, some environment variables would grow
2008 without limit.
2009
Benjamin Peterson37346b22008-08-23 20:27:43 +00002010- Issue #3643: Added a few more checks to _testcapi to prevent segfaults by
2011 exploitation of poor argument checking.

Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00002047What's New in Python 2.6 beta 3?
2048================================
2049
Barry Warsaw07a4a382008-08-21 01:15:08 +00002050*Release date: 20-Aug-2008*
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00002051
2052Core and Builtins
2053-----------------
2054
Guido van Rossumf8402962008-08-20 15:01:50 +00002055- Issue #1878: Remove Py_TPFLAGS_HAVE_VERSION_TAG from
2056 Py_TPFLAGS_DEFAULT when not building the core. This means 3rd party
2057 extensions do not automatically benefit from the class attribute
2058 cache; they will have to explicitly add Py_TPFLAGS_HAVE_VERSION_TAG
2059 to their tp_flags field if they care. This is a backwards
2060 compatibility feature; in 3.0, all types will use the cache by
2061 default.
2062
Benjamin Petersonf647dc12008-08-20 01:27:30 +00002063- Keyword arguments can now follow starred arguments. (``f(a, *args,
2064 keyword=23)`` is now valid syntax.)
2065
Thomas Heller0ad5ae02008-08-19 19:25:04 +00002066- ctypes function pointers that are COM methods have a boolean True
2067 value again.
2068
Martin v. Löwisf91d46a2008-08-12 14:49:50 +00002069- Issue #3139: Make buffer-interface thread-safe wrt. PyArg_ParseTuple,
2070 by denying s# to parse objects that have a releasebuffer procedure,
2071 and introducing s*.
2072
Georg Brandl1e13ea92008-08-11 09:07:59 +00002073- Issue #3537: Fix an assertion failure when an empty but presized dict
2074 object was stored in the freelist.
2075
Mark Dickinsonb6467572008-08-04 21:30:09 +00002076- Issue #1481296: Make long(float('nan')) and int(float('nan')) raise
2077 ValueError consistently across platforms.
2078
Amaury Forgeot d'Arc39fd6722008-07-31 21:28:03 +00002079- Issue #3479: On platforms where sizeof(int) is smaller than sizeof(long)
2080 (64bit Unix, for example), unichr() would truncate its argument and return
2081 u'\x00' for unichr(2**32). Now it properly raises an OverflowError.
2082
Neal Norwitze7d8be82008-07-31 17:17:14 +00002083- Apply security patches from Apple.
2084
Amaury Forgeot d'Arc246daed2008-07-31 00:42:16 +00002085- Issue #2542: Now that issubclass() may call arbitrary code, ensure that
2086 PyErr_ExceptionMatches returns 0 when an exception occurs there.
2087
Antoine Pitrou92f82162008-07-25 22:22:08 +00002088- Issue #1819: function calls with several named parameters are now on
2089 average 35% faster (as measured by pybench).
2090
Amaury Forgeot d'Arce4921fe2008-07-21 22:00:38 +00002091- Issue #2378: An unexpected UnboundLocalError or NameError could appear when
2092 the python debugger steps into a class statement: the free variables (local
2093 variables defined in an outer scope) would be deleted from the outer scope.
2094
Gregory P. Smith0470bab2008-07-22 04:46:32 +00002095- Issue #2620: Overflow checking when allocating or reallocating memory
2096 was not always being done properly in some python types and extension
2097 modules. PyMem_MALLOC, PyMem_REALLOC, PyMem_NEW and PyMem_RESIZE have
2098 all been updated to perform better checks and places in the code that
2099 would previously leak memory on the error path when such an allocation
2100 failed have been fixed.
2101
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00002102Library
2103-------
2104
Hirokazu Yamamoto838c79f2008-08-20 13:14:07 +00002105- Issue #3612: Added some missing basic types in ctypes.wintypes.
2106
Benjamin Petersone977ad42008-08-20 01:42:01 +00002107- The methods ``is_in_tuple()``, ``is_vararg()``, and ``is_keywordarg()`` of
2108 symtable.Symbol have been deprecated for removal in 3.0 and the next release.
2109
Amaury Forgeot d'Arc351ffb82008-08-18 19:23:47 +00002110- Issue #2234: distutils failed for some versions of the cygwin compiler. The
2111 version reported by these tools does not necessarily follow the python
2112 version numbering scheme, so the module is less strict when parsing it.
2113
Nick Coghlanf70385a2008-08-18 12:42:46 +00002114- Issue #2235: Added Py3k warnings for types which will become unhashable
2115 under the stricter __hash__ inheritance rules in 3.0. Several types
2116 which did not meet the rules for hash invariants and were already
2117 unhashable in 3.0 have now been explicitly flagged as unhashable in
2118 2.6 as well (collections.Mapping, collections.Set, unittest.TestSuite,
2119 xml.dom.minidom.NamedNodeMap, numbers.Number, UserList.UserList)
2120
Brett Cannon88f801d2008-08-18 00:46:22 +00002121- Update __all__ for cookielib, csv, os, urllib2, and weakref to include things
2122 imported into the module but exposed as part of the module's API.
2123
Brett Cannon7b96f072008-08-18 00:41:11 +00002124- Remove an unneeded import of abc.ABCMeta from 'inspect'.
2125
Brett Cannon46225e72008-08-18 00:36:52 +00002126- Remove unneeded imports of 'sys' and 'warnings' from 'io'.

Brett Cannon25c9d6a2008-08-17 22:10:11 +00002128- Remove unneeded imports of 'warnings' from shelve, filecmp, and dummy_thread.
2129
Hirokazu Yamamoto41a81eb2008-08-17 13:10:46 +00002130- Issue #3575: Incremental decoder's decode function now takes bytearray
2131 by using 's*' instead of 't#'.
2132
Jesus Cea585ad8a2009-07-02 15:37:21 +00002133- Issue #2222: Fixed reference leak when occurred os.rename()
Hirokazu Yamamoto7f30a682008-08-17 09:46:56 +00002134 fails unicode conversion on 2nd parameter. (windows only)
2135
Georg Brandl21896072010-08-01 22:31:28 +00002136- Issue #2464: urllib2 now supports a malformation in the URL received
Facundo Batista94f243a2008-08-17 03:38:39 +00002137 in a redirect.
2138
Brett Cannonabe423e2008-08-16 21:47:07 +00002139- Silence the DeprecationWarning raised when importing mimetools in
Brett Cannon721b1452008-08-16 22:00:27 +00002140 BaseHTTPServer, cgi (and rfc822), httplib.
Brett Cannonabe423e2008-08-16 21:47:07 +00002141
Facundo Batistaeb90b782008-08-16 14:44:07 +00002142- Issue #2776: fixed small issue when handling an URL with double slash
2143 after a 302 response in the case of not going through a proxy.
2144
Antoine Pitroub90a8be2008-08-15 21:03:21 +00002145- Issue #2676: in the email package, content-type parsing was hanging on
2146 pathological input because of quadratic or exponential behaviour of a
2147 regular expression.
2148
Antoine Pitrou11ec65d2008-08-14 21:04:30 +00002149- Issue #3476: binary buffered reading through the new "io" library is now
2150 thread-safe.
2151
Brett Cannonbf3157b2008-08-14 05:00:03 +00002152- Silence the DeprecationWarning of rfc822 when it is imported by mimetools
2153 since mimetools itself is deprecated. Because modules are cached, all

2243
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00002244*Release date: 17-Jul-2008*

2247-----------------
2248
Georg Brandl3e483f62008-07-16 22:57:41 +00002249- Issue #3156: Fix inconsistent behavior of the bytearray type: all
2250 its methods now allow for items objects that can be converted to
2251 an integer using operator.index().
2252
Mark Dickinson64b7e502008-07-16 09:40:03 +00002253- Issue #3360: Fix incorrect parsing of '020000000000.0', which
2254 produced a ValueError instead of giving the correct float.
2255
Eric Smitha5fa5a22008-07-16 00:11:49 +00002256- Issue #3083: Add alternate (#) formatting for bin, oct, hex output
2257 for str.format(). This adds the prefix 0b, 0o, or 0x, respectively.
2258
Mark Dickinson7103aa42008-07-15 19:08:33 +00002259- Issue #3008: the float type has a new instance method 'float.hex'
2260 and a new class method 'float.fromhex' to convert floating-point
2261 numbers to and from hexadecimal strings, respectively.
2262
Nick Coghlan6d6bd442008-07-15 15:40:22 +00002263- Issue #2235: __hash__ is once again inherited by default. To allow
2264 collections.Hashable to remain meaningful in the presence of the
2265 default hash implementation (object.__hash__), it is now possible
2266 to explicit block inheritance of hash by setting __hash__=None at
2267 the Python level, or tp_hash=PyObject_HashNotImplemented at the C
2268 level.
2269
Nick Coghlanb028f502008-07-13 14:52:36 +00002270- Issue #3221: Issue a RuntimeWarning instead of raising SystemError if
2271 the parent module cannot be found while performing an absolute import.
2272 This means that an incorrectly defined __package__ attribute will
2273 now only prevent relative imports in that module rather than causing
2274 all imports from that module to fail.
2275
Nick Coghlan14ff9942008-07-08 14:21:42 +00002276- Issue #2517: Allow unicode messages in Exceptions again by correctly

2285 threading.local: the first member set by a thread could be saved in
2286 another thread's dictionary.
2287
Mark Dickinson1ec2fcd2008-06-20 14:53:43 +00002288- Issue #3004: Minor change to slice.indices(): the start and stop
2289 arguments are now treated identically, making the behaviour easier
2290 to describe and understand. For example, slice(None, -10,
2291 1).indices(9) now returns (0, 0, 1) instead of (0, -1, 1), and
2292 slice(None, 10, -1).indices(10) returns (9, 9, -1) instead of (9,
2293 10, -1).
2294
Georg Brandl278fc502008-07-19 12:46:12 +00002295- Issue #3219: Calling a function with repeated keyword arguments,
2296 f(a=2, a=23), would not cause a syntax error. This was a regression
2297 from 2.4 caused by the switch to the new compiler.
Benjamin Peterson175e4d92008-07-01 19:34:52 +00002298
Georg Brandl278fc502008-07-19 12:46:12 +00002299- Issue #2862: Make int and float freelist management consistent with
2300 other freelists. Changes their CompactFreeList apis into
2301 ClearFreeList apis and calls them via gc.collect().

2309
Martin v. Löwisaabf4042008-08-02 07:20:25 +00002310- Issue #799428: Fix Tkinter.Misc._nametowidget to unwrap Tcl command objects.

Amaury Forgeot d'Arc0f7cddc2008-07-06 21:34:39 +00002335- Issue #839496: SimpleHTTPServer used to open text files in text mode. This is
2336 both unnecessary (HTTP allows text content to be sent in several forms) and
Andrew M. Kuchlingcc3f2b12008-07-10 14:43:31 +00002337 wrong because the actual transmitted size could differ from the
Amaury Forgeot d'Arc0f7cddc2008-07-06 21:34:39 +00002338 content-length. The problem had been corrected in the 2.4 branch, but never

Nick Coghlanc060b0e2008-07-02 13:09:19 +00002354- Issue #3190: Pydoc now hides the automatic module attribute __package__ (the

2723 in Python 3.0.
Benjamin Peterson23681932008-05-12 21:42:13 +00002724
Vinay Sajip9828b7e2008-06-17 11:04:02 +00002725- Library: on MacOS X you can now set ``ARCHFLAGS`` in the shell
Ronald Oussoren5640ce22008-06-05 12:58:24 +00002726 environment to control the '-arch' flags that are used to build
2727 an extension. This was added for compatibility with Apple's build
2728 of Python.
2729
2730- The bundled OSX-specific copy of libbffi is now in sync with the version
2731 shipped with PyObjC 2.0 and includes support for x86_64 and ppc64 platforms.
2732
Georg Brandl25c34082008-08-18 23:09:49 +00002733- The threading module gained aliases for names that will be removed in the

2742
Brett Cannonb61d8012008-05-11 23:39:04 +00002743- ``Lib/lib-old`` is now added to sys.path.
2744
Ronald Oussoren5640ce22008-06-05 12:58:24 +00002745- On MacOS X it is now possible to install the framework in 64-bit
2746 mode or even as a 4-way universal binary (that is, PPC, i386,
Georg Brandl5cc774e2008-06-11 20:28:06 +00002747 PPC64 and x86_64 support in one binary).
Ronald Oussoren5640ce22008-06-05 12:58:24 +00002748
2749 This is controlled by the configure argument ``--with-universal-archs``:
2750
2751 - ``--with-universal-archs=all``: install 4-way universal
2752
2753 - ``--with-universal-archs=32-bit``: install 2-way universal, 32-bit (the default)
2754
2755 - ``--with-universal-archs=64-bit``: install 2-way universal, 64-bit
2756
2757 This option should be used in combination with ``--enable-universalsdk=``.
2758
2759 NOTE: 64-bit and 4-way builds are only suppported on Mac OS X 10.5 (or later).

Christian Heimes7a990612008-05-26 13:15:11 +00002768
2769- The PyString functions have been renamed to PyBytes. A batch of
2770 defines were added so that the linker still sees the original
2771 PyString names.

Georg Brandl3ee81df2008-05-17 18:14:43 +00002809- Issue #1631171: Re-implement the 'warnings' module in C (the
2810 original Python code has been kept as backup). This will allow for
2811 using the 'warning's machinery in such places as the parser where
2812 use of pure Python code is not possible. Both the ``showarning()``
2813 and ``formatwarning()`` gain an optional 'line' argument which is
2814 not called by default for backwards-compatibility reasons. Setting
2815 ``warnings.showwarning()`` to an implementation that lacks support
2816 for the ``line`` argument will raise a DeprecationWarning.

Gregory P. Smithd59fefb2008-04-22 08:11:33 +00002841- The getpass module has been improved on Unix. It now uses /dev/tty
2842 by default and uses stderr instead of stdout. A GetPassWarning is
2843 issued when input echo cannot be controlled.

Georg Brandl3ee81df2008-05-17 18:14:43 +00002858- Issue #2513: distutils on Windows is now capable of cross-compiling
Mark Hammond495cf992008-04-07 01:53:39 +00002859 extension modules between 32 and 64 bit platforms. See the distutls

Georg Brandl3ee81df2008-05-17 18:14:43 +00002879- Issue #2550: The approach used by client/server code for obtaining
2880 ports to listen on in network-oriented tests has been refined in an
2881 effort to facilitate running multiple instances of the entire
2882 regression test suite in parallel without issue.
2883 test_support.bind_port() has been fixed such that it will always
2884 return a unique port -- which wasn't always the case with the
2885 previous implementation, especially if socket options had been set
2886 that affected address reuse (i.e. SO_REUSEADDR, SO_REUSEPORT). The
2887 new implementation of bind_port() will actually raise an exception
2888 if it is passed an AF_INET/SOCK_STREAM socket with either the
2889 SO_REUSEADDR or SO_REUSEPORT socket option set. Furthermore, if
2890 available, bind_port() will set the SO_EXCLUSIVEADDRUSE option on
2891 the socket it's been passed. This currently only applies to
2892 Windows. This option prevents any other sockets from binding to the
2893 host/port we've bound to, thus removing the possibility of the
2894 'non-deterministic' behaviour, as Microsoft puts it, that occurs
2895 when a second SOCK_STREAM socket binds and accepts to a host/port
2896 that's already been bound by another socket. The optional preferred
2897 port parameter to bind_port() has been removed. Under no
2898 circumstances should tests be hard coding ports!
2899
2900 test_support.find_unused_port() has also been introduced, which will
2901 pass a temporary socket object to bind_port() in order to obtain an
2902 unused port. The temporary socket object is then closed and
2903 deleted, and the port is returned. This method should only be used
2904 for obtaining an unused port in order to pass to an external program
2905 (i.e. the -accept [port] argument to openssl's s_server mode) or as
2906 a parameter to a server-oriented class that doesn't give you direct
2907 access to the underlying socket used.
2908
2909 Finally, test_support.HOST has been introduced, which should be used
2910 for the host argument of any relevant socket calls (i.e. bind and
2911 connect).
Trent Nelsone41b0062008-04-08 23:47:30 +00002912
2913 The following tests were updated to following the new conventions:
Georg Brandl3ee81df2008-05-17 18:14:43 +00002914 test_socket, test_smtplib, test_asyncore, test_ssl, test_httplib,
Trent Nelsone41b0062008-04-08 23:47:30 +00002915 test_poplib, test_ftplib, test_telnetlib, test_socketserver,
2916 test_asynchat and test_socket_ssl.
2917
Georg Brandl3ee81df2008-05-17 18:14:43 +00002918 It is now possible for multiple instances of the regression test
2919 suite to run in parallel without issue.

Eric Smitha73fbe72008-02-23 03:09:44 +00003198- Added the future_builtins module, which contains hex() and oct().
3199 These are the PEP 3127 version of these functions, designed to be
3200 compatible with the hex() and oct() builtins from Python 3.0. They
3201 differ slightly in their output formats from the existing, unchanged
3202 Python 2.6 builtins. The expected usage of the future_builtins
3203 module is:
3204 from future_builtins import hex, oct
3205
Eric Smith7ef40bf2008-02-20 23:34:22 +00003206- Issue #1600: Modifed PyOS_ascii_formatd to use at most 2 digit
3207 exponents for exponents with absolute value < 100. Follows C99
3208 standard. This is a change on Windows, which would use 3 digits.
3209 Also, added 'n' to the formats that PyOS_ascii_formatd understands,
3210 so that any alterations it does to the resulting string will be
3211 available in stringlib/formatter.h (for float.__format__).
3212
Eric Smith5a3c1352008-02-19 13:21:56 +00003213- Implemented PEP 3101, Advanced String Formatting. This adds a new
3214 builtin format(); a format() method for str and unicode; a
3215 __format__() method to object, str, unicode, int, long, float, and
3216 datetime; the class string.Formatter; and the C API
3217 PyObject_Format().
3218
Georg Brandl3ee81df2008-05-17 18:14:43 +00003219- Fixed several potential crashes, all caused by specially crafted
3220 __del__ methods exploiting objects in temporarily inconsistent
3221 state.

Vinay Sajipb7edfc42008-04-02 21:10:23 +00003223- Issue #2115: Important speedup in setting __slot__ attributes. Also
Georg Brandl3ee81df2008-05-17 18:14:43 +00003224 prevent a possible crash: an Abstract Base Class would try to access
3225 a slot on a registered virtual subclass.

3231 in order to allow pymalloc to free more arenas. Python may give back
3232 memory to the OS earlier.
Christian Heimes3b718a72008-02-14 12:47:33 +00003233
Georg Brandl3ee81df2008-05-17 18:14:43 +00003234- Issue #2045: Fix an infinite recursion triggered when printing a
3235 subclass of collections.defaultdict, if its default_factory is set
3236 to a bound method.
Amaury Forgeot d'Arcb01aa432008-02-08 00:56:02 +00003237
Christian Heimesf75dbef2008-02-08 00:11:31 +00003238- Fixed a minor memory leak in dictobject.c. The content of the free
3239 list was not freed on interpreter shutdown.

Georg Brandl5a7eca12010-03-21 19:29:04 +00003241- Limit free list of method and built-in function objects to 256
Georg Brandl3ee81df2008-05-17 18:14:43 +00003242 entries each.
Christian Heimes6075a822008-02-06 12:44:34 +00003243
Georg Brandl3ee81df2008-05-17 18:14:43 +00003244- Patch #1953: Added ``sys._compact_freelists()`` and the C API
3245 functions ``PyInt_CompactFreeList`` and ``PyFloat_CompactFreeList``
Christian Heimes422051a2008-02-04 18:00:12 +00003246 to compact the internal free lists of pre-allocted ints and floats.
3247
Georg Brandl3ee81df2008-05-17 18:14:43 +00003248- Issue #1983: Fixed return type of fork(), fork1() and forkpty()
3249 calls. Python expected the return type int but the fork familie
3250 returns pi_t.
Christian Heimes951cc0f2008-01-31 23:08:23 +00003251
Georg Brandl3ee81df2008-05-17 18:14:43 +00003252- Issue #1678380: Fix a bug that identifies 0j and -0j when they
3253 appear in the same code unit.
Mark Dickinson105be772008-01-31 22:17:37 +00003254
Georg Brandl3ee81df2008-05-17 18:14:43 +00003255- Issue #2025: Add tuple.count() and tuple.index() methods to comply
3256 with the collections.Sequence API.
Raymond Hettinger5b07ebc2008-02-07 00:54:20 +00003257
Georg Brandl3ee81df2008-05-17 18:14:43 +00003258- Patch #1970 by Antoine Pitrou: Speedup unicode whitespace and
3259 linebreak detection

Georg Brandl3ee81df2008-05-17 18:14:43 +00003261- Added ``PyType_ClearCache()`` and ``sys._clear_type_cache`` to clear
3262 the internal lookup cache for ref leak tests.
Christian Heimes908caac2008-01-27 23:34:59 +00003263
Georg Brandl3ee81df2008-05-17 18:14:43 +00003264- Patch #1473257: generator objects gain a gi_code attribute. This is
3265 the same object as the func_code attribute of the function that
3266 produced the generator.
Georg Brandl0cdf9a32008-01-26 14:14:20 +00003267
Georg Brandl3ee81df2008-05-17 18:14:43 +00003268- Issue #1920: "while 0" statements were completely removed by the
3269 compiler, even in the presence of an "else" clause, which is
3270 supposed to be run when the condition is false. Now the compiler
3271 correctly emits bytecode for the "else" suite.
Amaury Forgeot d'Arc31eaafe2008-01-24 22:59:25 +00003272
Guido van Rossumeead05f2008-01-24 18:21:02 +00003273- A few crashers fixed: weakref_in_del.py (issue #1377858);
3274 loosing_dict_ref.py (issue #1303614, test67.py);
3275 borrowed_ref_[34].py (not in tracker).
3276
Vinay Sajipd7cf32e2008-01-24 12:43:33 +00003277- Issue #1069410: The "can't load dll" message box on Windows is
Christian Heimesb2302ba2008-01-23 17:15:06 +00003278 suppressed while an extension is loaded by calling SetErrorMode in
3279 dynload_win.c. The error is still reported properly.
3280
Georg Brandl3ee81df2008-05-17 18:14:43 +00003281- Issue #1915: Python compiles with --enable-unicode=no again. However
Christian Heimes082c9b02008-01-23 14:20:50 +00003282 several extension methods and modules do not work without unicode
3283 support.
3284
Georg Brandl26543b12008-01-21 18:36:51 +00003285- Issue #1882: when compiling code from a string, encoding cookies in the
3286 second line of code were not always recognized correctly.
3287
Georg Brandl14404b62008-01-19 19:27:05 +00003288- Issue #1679: "0x" was taken as a valid integer literal.
3289
Georg Brandl6caad7d2008-01-26 14:19:22 +00003290- Issue #1865: ``bytes`` as an alias for ``str`` and b"" as an alias "" were
Christian Heimes288e89a2008-01-18 18:24:07 +00003291 added.
3292
Christian Heimesc94e2b52008-01-14 04:13:37 +00003293- sys.float_info / PyFloat_GetInfo: The floating point information
3294 object was converted from a dict to a specialized structseq object.
3295
Georg Brandl3ee81df2008-05-17 18:14:43 +00003296- Patch #1816: Added sys.flags structseq. It exposes the status of
3297 most command line arguments and PYTHON* environment variables.
Christian Heimesf31b69f2008-01-14 03:42:48 +00003298
Georg Brandl3ee81df2008-05-17 18:14:43 +00003299- Objects/structseq.c: Implemented new structseq representation. The
3300 patch makes structseqs (e.g. the return value of os.stat) more
3301 readable.
Christian Heimes9c201962008-01-14 03:33:52 +00003302
Georg Brandl3ee81df2008-05-17 18:14:43 +00003303- Patch #1700288: added a type attribute cache that caches method
3304 accesses, resulting in speedups in heavily object-oriented code.
Amaury Forgeot d'Arce4c270c2008-01-14 00:29:41 +00003305
Neal Norwitz3fc15b82008-01-10 05:42:58 +00003306- Bug #1776: __import__() no longer accepts filenames on any platform.
3307 The first parameter to __import__() must be a valid module name.
Christian Heimes3403f152008-01-09 19:56:33 +00003308
Georg Brandlaed6c662008-01-07 17:25:53 +00003309- Patch #1668: renamed THREADDEBUG envvar to PYTHONTHREADDEBUG.
3310
Georg Brandl3ee81df2008-05-17 18:14:43 +00003311- Patch #602345: Add -B command line option, PYTHONDONTWRITEBYTECODE
3312 envvar and sys.dont_write_bytecode attribute. All these can be set
3313 to forbid Python to attempt to write compiled bytecode files.
Georg Brandl2da0fce2008-01-07 17:09:35 +00003314
Georg Brandl3ee81df2008-05-17 18:14:43 +00003315- Improve some exception messages when Windows fails to load an
3316 extension module. Now we get for example '%1 is not a valid Win32
3317 application' instead of 'error code 193'.
Amaury Forgeot d'Arce0b76952008-01-04 02:04:15 +00003318
Georg Brandl3ee81df2008-05-17 18:14:43 +00003319- Bug #1481296: Fixed long(float('nan')) != 0L.

Georg Brandl3ee81df2008-05-17 18:14:43 +00003321- Issue #1640: Added math.isinf(x), math.isnan(x) and math.copysign(x,
3322 y) functions.
Christian Heimese2ca4242008-01-03 20:23:15 +00003323
Christian Heimes0a8143f2007-12-18 23:22:54 +00003324- Issue #1635: Platform independent creation and representation of NaN
Georg Brandl3ee81df2008-05-17 18:14:43 +00003325 and INF. float("nan"), float("inf") and float("-inf") now work on
3326 every platform with IEEE 754 semantics.
Christian Heimes0a8143f2007-12-18 23:22:54 +00003327
Georg Brandl3ee81df2008-05-17 18:14:43 +00003328- Compiler now generates simpler and faster code for dictionary
3329 literals. The oparg for BUILD_MAP now indicates an estimated
3330 dictionary size. There is a new opcode, STORE_MAP, for adding
3331 entries to the dictionary.
Raymond Hettingerfd7ed402007-12-18 21:24:09 +00003332
Georg Brandl3ee81df2008-05-17 18:14:43 +00003333- Issue #1638: %zd configure test fails on Linux.

Andrew M. Kuchling395fe442007-12-05 13:27:20 +00003341- Issue #1553: An erroneous __length_hint__ can make list() raise a
Christian Heimes7cc1c6f2007-12-05 12:52:34 +00003342 SystemError.
3343
Nick Coghlanef01d822007-12-03 12:55:17 +00003344- PEP 366: Allow explicit relative imports when executing modules

Georg Brandl3ee81df2008-05-17 18:14:43 +00003360- Patch #1739468: Directories and zipfiles containing a __main__.py
3361 file can now be directly executed by passing their name to the
3362 interpreter. The directory/zipfile is automatically inserted as the
3363 first entry in sys.path.
Nick Coghlan327a39b2007-11-18 11:56:28 +00003364
Georg Brandl3ee81df2008-05-17 18:14:43 +00003365- Issue #1265: Fix a problem with sys.settrace, if the tracing
3366 function uses a generator expression when at the same time the
3367 executed code is closing a paused generator.
Amaury Forgeot d'Arc0d75f092007-11-13 21:54:28 +00003368
Raymond Hettinger1760c8a2007-11-08 02:52:43 +00003369- sets and frozensets now have an isdisjoint() method.
3370
Raymond Hettinger3f8caa32007-10-24 01:28:33 +00003371- optimize the performance of builtin.sum().
3372
Neal Norwitz44f326e2007-10-05 05:29:17 +00003373- Fix warnings found by the new version of the Coverity checker.
3374
Georg Brandl5a7eca12010-03-21 19:29:04 +00003375- The enumerate() built-in function is no longer bounded to sequences
Georg Brandl3ee81df2008-05-17 18:14:43 +00003376 smaller than LONG_MAX. Formerly, it raised an OverflowError. Now,
3377 automatically shifts from ints to longs.
Raymond Hettinger8f669372007-10-03 21:18:11 +00003378
Georg Brandl3ee81df2008-05-17 18:14:43 +00003379- Issue #1686386: Tuple's tp_repr did not take into account the
3380 possibility of having a self-referential tuple, which is possible
3381 from C code. Nor did object's tp_str consider that a type's tp_str
3382 could do something that could lead to an inifinite recursion.
3383 Py_ReprEnter() and Py_EnterRecursiveCall(), respectively, fixed the
3384 issues.
Brett Cannon0b14f242007-09-30 19:45:10 +00003385
Georg Brandl3ee81df2008-05-17 18:14:43 +00003386- Issue #1164: It was possible to trigger deadlock when using the
3387 'print' statement to write to a file since the GIL was not released
3388 as needed. Now PyObject_Print() does the right thing along with
3389 various tp_print implementations of the built-in types and those in
3390 the collections module.
Brett Cannon01531592007-09-17 03:28:34 +00003391
Georg Brandl3ee81df2008-05-17 18:14:43 +00003392- Issue #1147: Exceptions were directly allowing string exceptions in
3393 their throw() method even though string exceptions no longer
3394 allowed.
Brett Cannon4c20bc42007-09-11 21:02:28 +00003395
Georg Brandl3ee81df2008-05-17 18:14:43 +00003396- Issue #1096: Prevent a segfault from getting the repr of a very
3397 deeply nested list by using the recursion counter.
Brett Cannona0c05512007-09-10 21:38:27 +00003398
Brett Cannon1e534b52007-09-07 04:18:30 +00003399- Issue #1202533: Fix infinite recursion calls triggered by calls to
Georg Brandl3ee81df2008-05-17 18:14:43 +00003400 PyObject_Call() never calling back out to Python code to trigger
3401 recursion depth updates/checks. Required the creation of a static
3402 RuntimeError instance in case normalizing an exception put the
3403 recursion check value past its limit. Fixes crashers
3404 infinite_rec_(1|2|4|5).py.
Brett Cannon1e534b52007-09-07 04:18:30 +00003405
Georg Brandl3ee81df2008-05-17 18:14:43 +00003406- Patch #1031213: Decode source line in SyntaxErrors back to its

Neal Norwitz0ac60192007-05-27 04:08:54 +00003419- Add new attribute names for function objects. All the func_* become
Georg Brandl3ee81df2008-05-17 18:14:43 +00003420 __*__ attributes. (Some already existed, e.g., __doc__ and
3421 __name__.)
Neal Norwitz0ac60192007-05-27 04:08:54 +00003422
Neal Norwitz8b2bfbc2007-05-23 06:35:32 +00003423- Add -3 option to the interpreter to warn about features that are
3424 deprecated and will be changed/removed in Python 3.0.
3425
Georg Brandl2134e752007-05-21 20:34:16 +00003426- Patch #1686487: you can now pass any mapping after '**' in function
3427 calls.
3428
Collin Winter62903052007-05-18 23:11:24 +00003429- except clauses may now be spelled either "except E, target:" or
Georg Brandl3ee81df2008-05-17 18:14:43 +00003430 "except E as target:". This is to provide forwards compatibility
3431 with Python 3.0.
Collin Winter62903052007-05-18 23:11:24 +00003432
Brett Cannon229cee22007-05-05 01:34:02 +00003433- Deprecate BaseException.message as per PEP 352.
3434
Georg Brandl3ee81df2008-05-17 18:14:43 +00003435- Issue #1303614: don't expose object's __dict__ when the dict is
Georg Brandl5a7eca12010-03-21 19:29:04 +00003436 inherited from a built-in base.
Armin Rigo9790a272007-05-02 19:23:31 +00003437
Vinay Sajip8549ce32007-05-06 17:53:37 +00003438- When __slots__ are set to a unicode string, make it work the same as
Neal Norwitzcbd9ee62007-04-14 05:25:50 +00003439 setting a plain string, ie don't expand to single letter identifiers.
3440
Raymond Hettinger13936692007-04-11 18:40:58 +00003441- Request #1191699: Slices can now be pickled.
3442
Raymond Hettinger4db5fe92007-04-12 04:10:00 +00003443- Request #1193128: str.translate() now allows a None argument for
3444 translations that only remove characters without re-mapping the
3445 remaining characters.
3446
Georg Brandl5cb76c12007-03-21 09:00:39 +00003447- Patch #1682205: a TypeError while unpacking an iterable is no longer
3448 masked by a generic one with the message "unpack non-sequence".
3449
Neal Norwitzaa754b72007-03-21 06:39:48 +00003450- Remove unused file Python/fmod.c.
3451
Guido van Rossum143b5642007-03-23 04:58:42 +00003452- Bug #1683368: The object.__init__() and object.__new__() methods are
3453 now stricter in rejecting excess arguments. The only time when
3454 either allows excess arguments is when it is not overridden and the
3455 other one is. For backwards compatibility, when both are
3456 overridden, it is a deprecation warning (for now; maybe a Py3k
Guido van Rossum234b1ff2007-03-23 19:39:01 +00003457 warning later). Also, type.__init__() insists on the same signature
3458 as supported by type.__new__().
Guido van Rossum143b5642007-03-23 04:58:42 +00003459
Georg Brandl3ee81df2008-05-17 18:14:43 +00003460- Patch #1675423: PyComplex_AsCComplex() now tries to convert an
3461 object to complex using its __complex__() method before falling back
3462 to the __float__() method. Therefore, the functions in the cmath
3463 module now can operate on objects that define a __complex__()
3464 method.

Georg Brandl3ee81df2008-05-17 18:14:43 +00004538 time so that opening a database previously created with the DB_DUP
4539 or DB_DUPSORT flag set will keep the proper behavior on subsequent
4540 opens. Specifically: dictionary assignment to a DB object will
4541 replace all values for a given key when the database allows
4542 duplicate values. DB users should use DB.put(k, v) when they want
4543 to store duplicates; not DB[k] = v.

4552 behavior of quoting dots if they are the second character of any
4553 line.
