Eric Smitha985a3a2009-05-05 18:26:08 +0000159- Issue #5920: For float.__format__, change the behavior with the
160 empty presentation type (that is, not one of 'e', 'f', 'g', or 'n')
161 to be like 'g' but with at least one decimal point and with a
162 default precision of 12. Previously, the behavior the same but with
163 a default precision of 6. This more closely matches str(), and
164 reduces surprises when adding alignment flags to the empty
165 presentation type. This also affects the new complex.__format__ in
166 the same way.
167

197
198- Issue #5515: 'n' formatting for ints, longs, and floats handles
199 leading zero formatting poorly.

232 reduce the size of collections and therefore the garbage collection overhead
233 on long-running programs, depending on their particular use of datatypes.
234
Mark Dickinson0b666bf2009-03-23 18:25:13 +0000235- Issue #5512: Rewrite PyLong long division algorithm (x_divrem) to

268 on a 64-bit system.
269
Antoine Pitrou76a4b892009-02-13 13:52:33 +0000270- Issue #5186: Reduce hash collisions for objects with no __hash__ method by

303 destroying them does not show quadratic performance. Based on a proposal by
Benjamin Petersond50a5d52009-07-13 00:03:20 +0000304 Martin von Löwis at
Antoine Pitrou4c5ecb72009-01-09 21:40:55 +0000305 http://mail.python.org/pipermail/python-dev/2008-June/080579.html.

308
Antoine Pitroue96d4ea2009-01-06 18:10:47 +0000309- Issue #1180193: When importing a module from a .pyc (or .pyo) file with
310 an existing .py counterpart, override the co_filename attributes of all
311 code objects if the original filename is obsolete (which can happen if the
312 file has been renamed, moved, or if it is accessed through different paths).
313 Patch by Ziga Seilnacht and Jean-Paul Calderone.
314
Martin v. Löwis5344c992009-01-02 20:32:55 +0000315- Issue #4075: Use OutputDebugStringW in Py_FatalError.
316
Hirokazu Yamamoto99a1b202009-01-01 15:45:39 +0000317- Issue #4797: IOError.filename was not set when _fileio.FileIO failed to open
318 file with `str' filename on Windows.
319
Antoine Pitrouaa687902009-01-01 14:11:22 +0000320- Issue #3680: Reference cycles created through a dict, set or deque iterator
321 did not get collected.
322
Nick Coghlan180e4002008-12-30 01:18:48 +0000323- Issue #4701: PyObject_Hash now implicitly calls PyType_Ready on types
324 where the tp_hash and tp_dict slots are both NULL.
325
Benjamin Peterson7af65562008-12-29 17:56:58 +0000326- Issue #4764: With io.open, IOError.filename is set when trying to open a
327 directory on POSIX systems.
328
Benjamin Petersonfe231b02008-12-29 17:47:42 +0000329- Issue #4764: IOError.filename is set when trying to open a directory on POSIX
330 systems.
331
Georg Brandl6425a2f2008-12-28 11:54:53 +0000332- Issue #4759: None is now allowed as the first argument of
333 bytearray.translate(). It was always allowed for bytes.translate().
334
Skip Montanarof205c132008-12-23 03:30:15 +0000335- Added test case to ensure attempts to read from a file opened for writing
336 fail.
337
Antoine Pitrou73c0e652008-12-17 22:46:54 +0000338- Issue #2467: gc.DEBUG_STATS reported invalid elapsed times. Also, always

348 context manager returns a value that cannot be converted to a bool.
349
Jeffrey Yasskinffd42cf2008-12-10 07:35:02 +0000350- Issue #4597: Fixed several opcodes that weren't always propagating
351 exceptions.
352
Mark Dickinson826f3fe2008-12-05 21:55:28 +0000353- Issue #4445: Replace "sizeof(PyStringObject)" with
354 "offsetof(PyStringObject, ob_sval) + 1" when allocating memory for
355 str instances. On a typical machine this saves 3 bytes of memory
356 (on average) per string allocation.
357
Amaury Forgeot d'Arcdc619012008-11-22 20:01:18 +0000358- Issue #3996: On Windows, the PyOS_CheckStack function would cause the
359 interpreter to abort ("Fatal Python error: Could not reset the stack!")
360 instead of throwing a MemoryError.
361
Raymond Hettinger7989a4d2008-12-03 15:42:10 +0000362- Issue #3689: The list reversed iterator now supports __length_hint__
363 instead of __len__. Behavior now matches other reversed iterators.
364
Benjamin Petersonc078f922008-11-21 22:27:24 +0000365- Issue #4367: Python would segfault during compiling when the unicodedata
366 module couldn't be imported and \N escapes were present.
367
Vinay Sajip213faca2008-12-03 23:22:58 +0000368- Issue #4233: Changed semantic of ``_fileio.FileIO``'s ``close()``
Amaury Forgeot d'Arc32265652008-11-20 23:34:31 +0000369 method on file objects with closefd=False. The file descriptor is still
370 kept open but the file object behaves like a closed file. The ``FileIO``
371 object also got a new readonly attribute ``closefd``.
372
Benjamin Peterson46cc6d12008-11-19 21:49:09 +0000373- Issue #4348: Some bytearray methods returned that didn't cause any change to
374 the bytearray, returned the same bytearray instead of a copy.
375
Amaury Forgeot d'Arc7cfe7ea2008-11-18 22:19:37 +0000376- Issue #4317: Fixed a crash in the imageop.rgb2rgb8() function.

Benjamin Petersondcee09d2008-10-31 02:16:05 +0000382- Issue #4225: ``from __future__ import unicode_literals`` didn't work in an
383 exec statement.
384
Amaury Forgeot d'Arc69a9c5b2008-10-30 21:18:34 +0000385- Issue #4176: Fixed a crash when pickling an object which ``__reduce__``
386 method does not return iterators for the 4th and 5th items.
387
Benjamin Petersonbdca9422008-10-26 20:21:13 +0000388- Issue #4209: Enabling unicode_literals and the print_function in the same
389 __future__ import didn't work.
390
Benjamin Peterson399b1fe2008-10-25 02:53:28 +0000391- Using ``nonlocal`` as a variable name will now raise a Py3k SyntaxWarning
Georg Brandl7fb00ad2008-10-25 07:00:52 +0000392 because it is a reserved word in 3.x.
Benjamin Peterson399b1fe2008-10-25 02:53:28 +0000393
Hirokazu Yamamoto10a018c2008-10-09 10:00:30 +0000394- On windows, os.chdir given unicode was not working if GetCurrentDirectoryW
395 returned a path longer than MAX_PATH. (But It's doubtful this code path is
396 really executed because I cannot move to such directory on win2k)
397
Amaury Forgeot d'Arcd78b9dc2008-10-07 20:32:10 +0000398- Issue #4069: When set.remove(element) is used with a set element, the element
399 is temporarily replaced with an equivalent frozenset. But the eventual
400 KeyError would always report the empty frozenset([]) as the missing key. Now
401 it correctly refers to the initial element.
402
Antoine Pitrouae5bece2008-12-06 21:29:24 +0000403- Issue #4509: Various issues surrounding resize of bytearray objects to
404 which there are buffer exports.

Gregory P. Smith2b3eb372009-04-05 23:48:26 +0000418- Issue #5705: os.setuid() would not accept values > 2**31-1 but pwd.getpwnam()
419 returned them on 64bit platforms.
420
Walter Dörwalded960ac2009-05-03 22:36:33 +0000421- Issue #5108: Handle %s like %S and %R in PyUnicode_FromFormatV(): Call
422 PyUnicode_DecodeUTF8() once, remember the result and output it in a second
423 step. This avoids problems with counting UTF-8 bytes that ignores the effect
424 of using the replace error handler in PyUnicode_DecodeUTF8().
425
Walter Dörwald726ba8e2009-05-06 14:32:35 +0000426- Issue #3739: The unicode-internal encoder now reports the number of characters
427 consumed like any other encoder (instead of the number of bytes).

1571 leak-chasing test runs give sensible results. The previous method of
1572 reaping threads could return successfully while some Thread objects were
1573 still referenced. This also introduces a new private function:

1592 Lib/lib-tk/test/test_tkinter/test_loadtk. With this, these tests demonstrate

Georg Brandl2bd92a52009-10-11 21:10:07 +00001694- Issue #3850: recursion tests in Tools/scripts/find_recursion_limit.py can raise
Antoine Pitrou3c9f5412008-09-13 20:30:30 +00001695 AttributeError instead of RuntimeError, depending in which C API call
1696 exactly the recursion limit is exceeded. Consequently, both exception types
1697 are caught and silenced.

1711Core and Builtins
1712-----------------
1713
Martin v. Löwis9fa5a282008-09-11 06:53:30 +00001714- Issue #3642: Suppress warning in obmalloc when size_t is larger than uint.
1715
Amaury Forgeot d'Arc05e34492008-09-10 22:04:45 +00001716- Issue #3743: In a few places, PY_FORMAT_SIZE_T was incorrectly used with
1717 PyString_FromFormat or PyErr_Format to display size_t values. The macro
1718 PY_FORMAT_SIZE_T is designed to select the correct format for the OS
1719 ``printf`` function, whereas PyString_FromFormat has an independent
1720 implementation and uses "%zd" on all platforms for size_t values.
1721 This makes a difference on win64, where ``printf`` needs "%Id" to display
1722 64bit values.
1723
Benjamin Peterson97179b02008-09-09 20:55:01 +00001724- Issue #3634: _weakref.ref(Exception).__init__() gave invalid return value on
1725 error.
1726
Amaury Forgeot d'Arcd3ffb892008-09-09 07:24:30 +00001727- Issue #3777: long() applied to a float object now always return a long
1728 object; previously an int would be returned for small values. the __long__
1729 method is allowed to return either an int or a long, but the behaviour of
1730 float objects should not change to respect backward compatibility.
1731
Amaury Forgeot d'Arc3571fbf2008-09-01 19:52:00 +00001732- Issue #3751: str.rpartition would perform a left-partition when called with
1733 a unicode argument.
1734
Benjamin Peterson17f03ca2008-09-01 14:18:30 +00001735- Issue #3683: Fix compilation when --without-threads is given.
1736
Antoine Pitroud4ae97b2008-08-29 18:39:48 +00001737- Issue #3668: Fix a memory leak with the "s*" argument parser in
Vinay Sajip35e3b032008-09-01 14:33:59 +00001738 PyArg_ParseTuple and friends, which occurred when the argument for "s*"
Antoine Pitroud4ae97b2008-08-29 18:39:48 +00001739 was correctly parsed but parsing of subsequent arguments failed.
1740
Vinay Sajip35e3b032008-09-01 14:33:59 +00001741- Issue #2534: speed up isinstance() and issubclass() by 50-70%, so as to
Antoine Pitrou0668c622008-08-26 22:42:08 +00001742 match Python 2.5 speed despite the __instancecheck__ / __subclasscheck__
1743 mechanism. In the process, fix a bug where isinstance() and issubclass(),
1744 when given a tuple of classes as second argument, were looking up
1745 __instancecheck__ / __subclasscheck__ on the tuple rather than on each
1746 type object.
1747
Neal Norwitz18aa3882008-08-24 05:04:52 +00001748- Fix crashes on memory allocation failure found with failmalloc.
1749
1750- Fix memory leaks found with valgrind and update suppressions file.
1751
1752- Fix compiler warnings in opt mode which would lead to invalid memory reads.
1753
1754- Fix problem using wrong name in decimal module reported by pychecker.
1755
Christian Heimes7d4c3172008-08-22 19:47:25 +00001756- Silenced another compiler warning about a used but not defined
1757 function 'stringlib_contains_obj'.
1758
Benjamin Peterson712ee922008-08-24 18:10:20 +00001759- Added warnings on the use of ``__getslice__``, ``__setslice__``, or
1760 ``__delslice__``.
1761
Gregory P. Smith2bb25cc2008-09-02 05:29:51 +00001762- Issue #3678: Correctly pass LDFLAGS and LDLAST to the linker on shared
1763 library targets in the Makefile.
1764
Gregory P. Smith980b99b2008-09-07 05:15:18 +00001765- Issue #1204: The configure script now tests for additional libraries
1766 that may be required when linking against readline. This fixes issues
1767 with x86_64 builds on some platforms (a few Linux flavors and OpenBSD).

1789
Nick Coghland2e09382008-09-11 12:11:06 +00001790- Issue #3781: Clean up the API for warnings.catch_warnings() by having it
Brett Cannon672237d2008-09-09 00:49:16 +00001791 return a list or None rather than a custom object.
1792
Benjamin Peterson6ac7d7c2008-09-06 19:28:11 +00001793- Issue #1638033: Cookie.Morsel gained the httponly attribute.

1817 warnings.catch_warnings() along with some API cleanup. Expanding the tests
1818 for catch_warnings() also led to an improvement in the raising of a
1819 DeprecationWarning related to warnings.warn_explicit().
1820
Benjamin Peterson973e6c22008-09-01 23:12:58 +00001821- The deprecation warnings for the old camelCase threading API were removed.

Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00001885What's New in Python 2.6 beta 3?
1886================================
1887
Barry Warsaw07a4a382008-08-21 01:15:08 +00001888*Release date: 20-Aug-2008*
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00001889
1890Core and Builtins
1891-----------------
1892
Guido van Rossumf8402962008-08-20 15:01:50 +00001893- Issue #1878: Remove Py_TPFLAGS_HAVE_VERSION_TAG from
1894 Py_TPFLAGS_DEFAULT when not building the core. This means 3rd party
1895 extensions do not automatically benefit from the class attribute
1896 cache; they will have to explicitly add Py_TPFLAGS_HAVE_VERSION_TAG
1897 to their tp_flags field if they care. This is a backwards
1898 compatibility feature; in 3.0, all types will use the cache by
1899 default.
1900
Benjamin Petersonf647dc12008-08-20 01:27:30 +00001901- Keyword arguments can now follow starred arguments. (``f(a, *args,
1902 keyword=23)`` is now valid syntax.)
1903
Thomas Heller0ad5ae02008-08-19 19:25:04 +00001904- ctypes function pointers that are COM methods have a boolean True
1905 value again.
1906
Martin v. Löwisf91d46a2008-08-12 14:49:50 +00001907- Issue #3139: Make buffer-interface thread-safe wrt. PyArg_ParseTuple,
1908 by denying s# to parse objects that have a releasebuffer procedure,
1909 and introducing s*.
1910
Georg Brandl1e13ea92008-08-11 09:07:59 +00001911- Issue #3537: Fix an assertion failure when an empty but presized dict
1912 object was stored in the freelist.
1913
Mark Dickinsonb6467572008-08-04 21:30:09 +00001914- Issue #1481296: Make long(float('nan')) and int(float('nan')) raise
1915 ValueError consistently across platforms.
1916
Amaury Forgeot d'Arc39fd6722008-07-31 21:28:03 +00001917- Issue #3479: On platforms where sizeof(int) is smaller than sizeof(long)
1918 (64bit Unix, for example), unichr() would truncate its argument and return
1919 u'\x00' for unichr(2**32). Now it properly raises an OverflowError.
1920
Neal Norwitze7d8be82008-07-31 17:17:14 +00001921- Apply security patches from Apple.
1922
Amaury Forgeot d'Arc246daed2008-07-31 00:42:16 +00001923- Issue #2542: Now that issubclass() may call arbitrary code, ensure that
1924 PyErr_ExceptionMatches returns 0 when an exception occurs there.
1925
Antoine Pitrou92f82162008-07-25 22:22:08 +00001926- Issue #1819: function calls with several named parameters are now on
1927 average 35% faster (as measured by pybench).
1928
Amaury Forgeot d'Arce4921fe2008-07-21 22:00:38 +00001929- Issue #2378: An unexpected UnboundLocalError or NameError could appear when
1930 the python debugger steps into a class statement: the free variables (local
1931 variables defined in an outer scope) would be deleted from the outer scope.
1932
Gregory P. Smith0470bab2008-07-22 04:46:32 +00001933- Issue #2620: Overflow checking when allocating or reallocating memory
1934 was not always being done properly in some python types and extension
1935 modules. PyMem_MALLOC, PyMem_REALLOC, PyMem_NEW and PyMem_RESIZE have
1936 all been updated to perform better checks and places in the code that
1937 would previously leak memory on the error path when such an allocation
1938 failed have been fixed.

1946 symtable.Symbol have been deprecated for removal in 3.0 and the next release.
1947
Amaury Forgeot d'Arc351ffb82008-08-18 19:23:47 +00001948- Issue #2234: distutils failed for some versions of the cygwin compiler. The
1949 version reported by these tools does not necessarily follow the python
1950 version numbering scheme, so the module is less strict when parsing it.
1951
Nick Coghlanf70385a2008-08-18 12:42:46 +00001952- Issue #2235: Added Py3k warnings for types which will become unhashable
1953 under the stricter __hash__ inheritance rules in 3.0. Several types
1954 which did not meet the rules for hash invariants and were already
1955 unhashable in 3.0 have now been explicitly flagged as unhashable in
1956 2.6 as well (collections.Mapping, collections.Set, unittest.TestSuite,
1957 xml.dom.minidom.NamedNodeMap, numbers.Number, UserList.UserList)
1958
Brett Cannon88f801d2008-08-18 00:46:22 +00001959- Update __all__ for cookielib, csv, os, urllib2, and weakref to include things

1967
Hirokazu Yamamoto41a81eb2008-08-17 13:10:46 +00001968- Issue #3575: Incremental decoder's decode function now takes bytearray
1969 by using 's*' instead of 't#'.
1970
Mark Dickinson3e4caeb2009-02-21 20:27:01 +00001971- Issue #2222: Fixed reference leak when occurred os.rename()
Hirokazu Yamamoto7f30a682008-08-17 09:46:56 +00001972 fails unicode conversion on 2nd parameter. (windows only)
1973
Facundo Batista94f243a2008-08-17 03:38:39 +00001974- Issue 2464. urllib2 now supports a malformation in the URL received
1975 in a redirect.

Antoine Pitroude781a42008-08-09 12:43:23 +00002028 asking for a specific length. This problem only affected files opened
2029 using the new "io" module, not the built-in open() function.

2072
Nick Coghlan2a0c2b12008-08-04 12:47:17 +00002073- Issue #643841: The language reference now provides more detailed

2085-----------------
2086
Georg Brandl3e483f62008-07-16 22:57:41 +00002087- Issue #3156: Fix inconsistent behavior of the bytearray type: all
2088 its methods now allow for items objects that can be converted to
2089 an integer using operator.index().
2090
Mark Dickinson64b7e502008-07-16 09:40:03 +00002091- Issue #3360: Fix incorrect parsing of '020000000000.0', which
2092 produced a ValueError instead of giving the correct float.
2093
Eric Smitha5fa5a22008-07-16 00:11:49 +00002094- Issue #3083: Add alternate (#) formatting for bin, oct, hex output
2095 for str.format(). This adds the prefix 0b, 0o, or 0x, respectively.
2096
Mark Dickinson7103aa42008-07-15 19:08:33 +00002097- Issue #3008: the float type has a new instance method 'float.hex'
2098 and a new class method 'float.fromhex' to convert floating-point
2099 numbers to and from hexadecimal strings, respectively.
2100
Nick Coghlan6d6bd442008-07-15 15:40:22 +00002101- Issue #2235: __hash__ is once again inherited by default. To allow
2102 collections.Hashable to remain meaningful in the presence of the
2103 default hash implementation (object.__hash__), it is now possible
2104 to explicit block inheritance of hash by setting __hash__=None at
2105 the Python level, or tp_hash=PyObject_HashNotImplemented at the C
2106 level.
2107
Nick Coghlanb028f502008-07-13 14:52:36 +00002108- Issue #3221: Issue a RuntimeWarning instead of raising SystemError if
2109 the parent module cannot be found while performing an absolute import.
2110 This means that an incorrectly defined __package__ attribute will
2111 now only prevent relative imports in that module rather than causing
2112 all imports from that module to fail.
2113
Nick Coghlan14ff9942008-07-08 14:21:42 +00002114- Issue #2517: Allow unicode messages in Exceptions again by correctly

2124 another thread's dictionary.
2125
Mark Dickinson1ec2fcd2008-06-20 14:53:43 +00002126- Issue #3004: Minor change to slice.indices(): the start and stop
2127 arguments are now treated identically, making the behaviour easier
2128 to describe and understand. For example, slice(None, -10,
2129 1).indices(9) now returns (0, 0, 1) instead of (0, -1, 1), and
2130 slice(None, 10, -1).indices(10) returns (9, 9, -1) instead of (9,
2131 10, -1).
2132
Georg Brandl278fc502008-07-19 12:46:12 +00002133- Issue #3219: Calling a function with repeated keyword arguments,
2134 f(a=2, a=23), would not cause a syntax error. This was a regression
2135 from 2.4 caused by the switch to the new compiler.
Benjamin Peterson175e4d92008-07-01 19:34:52 +00002136
Georg Brandl278fc502008-07-19 12:46:12 +00002137- Issue #2862: Make int and float freelist management consistent with
2138 other freelists. Changes their CompactFreeList apis into

2145 api functions without holding the GIL, which could lead to a fatal
2146 error when they failed.
2147
Martin v. Löwisaabf4042008-08-02 07:20:25 +00002148- Issue #799428: Fix Tkinter.Misc._nametowidget to unwrap Tcl command objects.

Amaury Forgeot d'Arc0f7cddc2008-07-06 21:34:39 +00002173- Issue #839496: SimpleHTTPServer used to open text files in text mode. This is
2174 both unnecessary (HTTP allows text content to be sent in several forms) and
Andrew M. Kuchlingcc3f2b12008-07-10 14:43:31 +00002175 wrong because the actual transmitted size could differ from the
Amaury Forgeot d'Arc0f7cddc2008-07-06 21:34:39 +00002176 content-length. The problem had been corrected in the 2.4 branch, but never
2177 merged into trunk.

Nick Coghlanc060b0e2008-07-02 13:09:19 +00002192- Issue #3190: Pydoc now hides the automatic module attribute __package__ (the

Vinay Sajip9828b7e2008-06-17 11:04:02 +00002563- Library: on MacOS X you can now set ``ARCHFLAGS`` in the shell
Ronald Oussoren5640ce22008-06-05 12:58:24 +00002564 environment to control the '-arch' flags that are used to build
2565 an extension. This was added for compatibility with Apple's build
2566 of Python.
2567
2568- The bundled OSX-specific copy of libbffi is now in sync with the version
2569 shipped with PyObjC 2.0 and includes support for x86_64 and ppc64 platforms.
2570
Georg Brandl25c34082008-08-18 23:09:49 +00002571- The threading module gained aliases for names that will be removed in the

2580
Brett Cannonb61d8012008-05-11 23:39:04 +00002581- ``Lib/lib-old`` is now added to sys.path.
2582
Ronald Oussoren5640ce22008-06-05 12:58:24 +00002583- On MacOS X it is now possible to install the framework in 64-bit
2584 mode or even as a 4-way universal binary (that is, PPC, i386,
Georg Brandl5cc774e2008-06-11 20:28:06 +00002585 PPC64 and x86_64 support in one binary).
Ronald Oussoren5640ce22008-06-05 12:58:24 +00002586
2587 This is controlled by the configure argument ``--with-universal-archs``:
2588
2589 - ``--with-universal-archs=all``: install 4-way universal
2590
2591 - ``--with-universal-archs=32-bit``: install 2-way universal, 32-bit (the default)
2592
2593 - ``--with-universal-archs=64-bit``: install 2-way universal, 64-bit
2594
2595 This option should be used in combination with ``--enable-universalsdk=``.
2596
2597 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 +00002647- Issue #1631171: Re-implement the 'warnings' module in C (the
2648 original Python code has been kept as backup). This will allow for
2649 using the 'warning's machinery in such places as the parser where
2650 use of pure Python code is not possible. Both the ``showarning()``
2651 and ``formatwarning()`` gain an optional 'line' argument which is
2652 not called by default for backwards-compatibility reasons. Setting
2653 ``warnings.showwarning()`` to an implementation that lacks support
2654 for the ``line`` argument will raise a DeprecationWarning.

Georg Brandl3ee81df2008-05-17 18:14:43 +00002696- Issue #2513: distutils on Windows is now capable of cross-compiling
Mark Hammond495cf992008-04-07 01:53:39 +00002697 extension modules between 32 and 64 bit platforms. See the distutls

Georg Brandl3ee81df2008-05-17 18:14:43 +00002717- Issue #2550: The approach used by client/server code for obtaining
2718 ports to listen on in network-oriented tests has been refined in an
2719 effort to facilitate running multiple instances of the entire
2720 regression test suite in parallel without issue.
2721 test_support.bind_port() has been fixed such that it will always
2722 return a unique port -- which wasn't always the case with the
2723 previous implementation, especially if socket options had been set
2724 that affected address reuse (i.e. SO_REUSEADDR, SO_REUSEPORT). The
2725 new implementation of bind_port() will actually raise an exception
2726 if it is passed an AF_INET/SOCK_STREAM socket with either the
2727 SO_REUSEADDR or SO_REUSEPORT socket option set. Furthermore, if
2728 available, bind_port() will set the SO_EXCLUSIVEADDRUSE option on
2729 the socket it's been passed. This currently only applies to
2730 Windows. This option prevents any other sockets from binding to the
2731 host/port we've bound to, thus removing the possibility of the
2732 'non-deterministic' behaviour, as Microsoft puts it, that occurs
2733 when a second SOCK_STREAM socket binds and accepts to a host/port
2734 that's already been bound by another socket. The optional preferred
2735 port parameter to bind_port() has been removed. Under no
2736 circumstances should tests be hard coding ports!
2737
2738 test_support.find_unused_port() has also been introduced, which will
2739 pass a temporary socket object to bind_port() in order to obtain an
2740 unused port. The temporary socket object is then closed and
2741 deleted, and the port is returned. This method should only be used
2742 for obtaining an unused port in order to pass to an external program
2743 (i.e. the -accept [port] argument to openssl's s_server mode) or as
2744 a parameter to a server-oriented class that doesn't give you direct
2745 access to the underlying socket used.
2746
2747 Finally, test_support.HOST has been introduced, which should be used
2748 for the host argument of any relevant socket calls (i.e. bind and
2749 connect).
Trent Nelsone41b0062008-04-08 23:47:30 +00002750
2751 The following tests were updated to following the new conventions:
Georg Brandl3ee81df2008-05-17 18:14:43 +00002752 test_socket, test_smtplib, test_asyncore, test_ssl, test_httplib,
Trent Nelsone41b0062008-04-08 23:47:30 +00002753 test_poplib, test_ftplib, test_telnetlib, test_socketserver,
2754 test_asynchat and test_socket_ssl.
2755
Georg Brandl3ee81df2008-05-17 18:14:43 +00002756 It is now possible for multiple instances of the regression test
2757 suite to run in parallel without issue.

3024-----------------
3025
Fred Drakea8ee94b2008-03-01 02:45:07 +00003026- Issue #2051: pyc and pyo files are no longer created with permission
Barry Warsaw52973612008-03-01 02:23:38 +00003027 644. The mode is now inherited from the py file.

Christian Heimes5224d282008-02-23 15:01:05 +00003032
Vinay Sajipb7edfc42008-04-02 21:10:23 +00003033- Issue #1881: An internal parser limit has been increased. Also see
Facundo Batistafc2d0102008-02-23 12:01:13 +00003034 issue 215555 for a discussion.
3035
Eric Smitha73fbe72008-02-23 03:09:44 +00003036- Added the future_builtins module, which contains hex() and oct().
3037 These are the PEP 3127 version of these functions, designed to be
3038 compatible with the hex() and oct() builtins from Python 3.0. They
3039 differ slightly in their output formats from the existing, unchanged
3040 Python 2.6 builtins. The expected usage of the future_builtins
3041 module is:
3042 from future_builtins import hex, oct
3043
Eric Smith7ef40bf2008-02-20 23:34:22 +00003044- Issue #1600: Modifed PyOS_ascii_formatd to use at most 2 digit
3045 exponents for exponents with absolute value < 100. Follows C99
3046 standard. This is a change on Windows, which would use 3 digits.
3047 Also, added 'n' to the formats that PyOS_ascii_formatd understands,
3048 so that any alterations it does to the resulting string will be
3049 available in stringlib/formatter.h (for float.__format__).
3050
Eric Smith5a3c1352008-02-19 13:21:56 +00003051- Implemented PEP 3101, Advanced String Formatting. This adds a new
3052 builtin format(); a format() method for str and unicode; a
3053 __format__() method to object, str, unicode, int, long, float, and
3054 datetime; the class string.Formatter; and the C API
3055 PyObject_Format().
3056
Georg Brandl3ee81df2008-05-17 18:14:43 +00003057- Fixed several potential crashes, all caused by specially crafted
3058 __del__ methods exploiting objects in temporarily inconsistent
3059 state.
Amaury Forgeot d'Arc632fad32008-02-16 20:55:24 +00003060
Vinay Sajipb7edfc42008-04-02 21:10:23 +00003061- Issue #2115: Important speedup in setting __slot__ attributes. Also
Georg Brandl3ee81df2008-05-17 18:14:43 +00003062 prevent a possible crash: an Abstract Base Class would try to access
3063 a slot on a registered virtual subclass.
Amaury Forgeot d'Arc60d6c7f2008-02-15 21:22:45 +00003064
Georg Brandl3ee81df2008-05-17 18:14:43 +00003065- Fixed repr() and str() of complex numbers with infinity or nan as
3066 real or imaginary part.
Christian Heimes2f0da532008-02-15 06:57:08 +00003067
Georg Brandl3ee81df2008-05-17 18:14:43 +00003068- Clear all free lists during a gc.collect() of the highest generation
3069 in order to allow pymalloc to free more arenas. Python may give back
3070 memory to the OS earlier.

Georg Brandl3ee81df2008-05-17 18:14:43 +00003072- Issue #2045: Fix an infinite recursion triggered when printing a
3073 subclass of collections.defaultdict, if its default_factory is set
3074 to a bound method.
Amaury Forgeot d'Arcb01aa432008-02-08 00:56:02 +00003075
Christian Heimesf75dbef2008-02-08 00:11:31 +00003076- Fixed a minor memory leak in dictobject.c. The content of the free
3077 list was not freed on interpreter shutdown.
3078
Georg Brandl3ee81df2008-05-17 18:14:43 +00003079- Limit free list of method and builtin function objects to 256
3080 entries each.
Christian Heimes6075a822008-02-06 12:44:34 +00003081
Georg Brandl3ee81df2008-05-17 18:14:43 +00003082- Patch #1953: Added ``sys._compact_freelists()`` and the C API
3083 functions ``PyInt_CompactFreeList`` and ``PyFloat_CompactFreeList``
Christian Heimes422051a2008-02-04 18:00:12 +00003084 to compact the internal free lists of pre-allocted ints and floats.
3085
Georg Brandl3ee81df2008-05-17 18:14:43 +00003086- Issue #1983: Fixed return type of fork(), fork1() and forkpty()
3087 calls. Python expected the return type int but the fork familie
3088 returns pi_t.
Christian Heimes951cc0f2008-01-31 23:08:23 +00003089
Georg Brandl3ee81df2008-05-17 18:14:43 +00003090- Issue #1678380: Fix a bug that identifies 0j and -0j when they
3091 appear in the same code unit.
Mark Dickinson105be772008-01-31 22:17:37 +00003092
Georg Brandl3ee81df2008-05-17 18:14:43 +00003093- Issue #2025: Add tuple.count() and tuple.index() methods to comply
3094 with the collections.Sequence API.
Raymond Hettinger5b07ebc2008-02-07 00:54:20 +00003095
Georg Brandl3ee81df2008-05-17 18:14:43 +00003096- Patch #1970 by Antoine Pitrou: Speedup unicode whitespace and
3097 linebreak detection

Georg Brandl3ee81df2008-05-17 18:14:43 +00003099- Added ``PyType_ClearCache()`` and ``sys._clear_type_cache`` to clear
3100 the internal lookup cache for ref leak tests.
Christian Heimes908caac2008-01-27 23:34:59 +00003101
Georg Brandl3ee81df2008-05-17 18:14:43 +00003102- Patch #1473257: generator objects gain a gi_code attribute. This is
3103 the same object as the func_code attribute of the function that
3104 produced the generator.
Georg Brandl0cdf9a32008-01-26 14:14:20 +00003105
Georg Brandl3ee81df2008-05-17 18:14:43 +00003106- Issue #1920: "while 0" statements were completely removed by the
3107 compiler, even in the presence of an "else" clause, which is
3108 supposed to be run when the condition is false. Now the compiler
3109 correctly emits bytecode for the "else" suite.
Amaury Forgeot d'Arc31eaafe2008-01-24 22:59:25 +00003110
Guido van Rossumeead05f2008-01-24 18:21:02 +00003111- A few crashers fixed: weakref_in_del.py (issue #1377858);
3112 loosing_dict_ref.py (issue #1303614, test67.py);
3113 borrowed_ref_[34].py (not in tracker).
3114
Vinay Sajipd7cf32e2008-01-24 12:43:33 +00003115- Issue #1069410: The "can't load dll" message box on Windows is
Christian Heimesb2302ba2008-01-23 17:15:06 +00003116 suppressed while an extension is loaded by calling SetErrorMode in
3117 dynload_win.c. The error is still reported properly.
3118
Georg Brandl3ee81df2008-05-17 18:14:43 +00003119- Issue #1915: Python compiles with --enable-unicode=no again. However
Christian Heimes082c9b02008-01-23 14:20:50 +00003120 several extension methods and modules do not work without unicode
3121 support.
3122
Georg Brandl26543b12008-01-21 18:36:51 +00003123- Issue #1882: when compiling code from a string, encoding cookies in the
3124 second line of code were not always recognized correctly.
3125
Georg Brandl14404b62008-01-19 19:27:05 +00003126- Issue #1679: "0x" was taken as a valid integer literal.
3127
Georg Brandl6caad7d2008-01-26 14:19:22 +00003128- Issue #1865: ``bytes`` as an alias for ``str`` and b"" as an alias "" were
Christian Heimes288e89a2008-01-18 18:24:07 +00003129 added.
3130
Christian Heimesc94e2b52008-01-14 04:13:37 +00003131- sys.float_info / PyFloat_GetInfo: The floating point information
3132 object was converted from a dict to a specialized structseq object.
3133
Georg Brandl3ee81df2008-05-17 18:14:43 +00003134- Patch #1816: Added sys.flags structseq. It exposes the status of
3135 most command line arguments and PYTHON* environment variables.
Christian Heimesf31b69f2008-01-14 03:42:48 +00003136
Georg Brandl3ee81df2008-05-17 18:14:43 +00003137- Objects/structseq.c: Implemented new structseq representation. The
3138 patch makes structseqs (e.g. the return value of os.stat) more
3139 readable.
Christian Heimes9c201962008-01-14 03:33:52 +00003140
Georg Brandl3ee81df2008-05-17 18:14:43 +00003141- Patch #1700288: added a type attribute cache that caches method
3142 accesses, resulting in speedups in heavily object-oriented code.
Amaury Forgeot d'Arce4c270c2008-01-14 00:29:41 +00003143
Neal Norwitz3fc15b82008-01-10 05:42:58 +00003144- Bug #1776: __import__() no longer accepts filenames on any platform.
3145 The first parameter to __import__() must be a valid module name.
Christian Heimes3403f152008-01-09 19:56:33 +00003146
Georg Brandlaed6c662008-01-07 17:25:53 +00003147- Patch #1668: renamed THREADDEBUG envvar to PYTHONTHREADDEBUG.
3148
Georg Brandl3ee81df2008-05-17 18:14:43 +00003149- Patch #602345: Add -B command line option, PYTHONDONTWRITEBYTECODE
3150 envvar and sys.dont_write_bytecode attribute. All these can be set
3151 to forbid Python to attempt to write compiled bytecode files.
Georg Brandl2da0fce2008-01-07 17:09:35 +00003152
Georg Brandl3ee81df2008-05-17 18:14:43 +00003153- Improve some exception messages when Windows fails to load an
3154 extension module. Now we get for example '%1 is not a valid Win32
3155 application' instead of 'error code 193'.
Amaury Forgeot d'Arce0b76952008-01-04 02:04:15 +00003156
Georg Brandl3ee81df2008-05-17 18:14:43 +00003157- Bug #1481296: Fixed long(float('nan')) != 0L.

Georg Brandl3ee81df2008-05-17 18:14:43 +00003159- Issue #1640: Added math.isinf(x), math.isnan(x) and math.copysign(x,
3160 y) functions.
Christian Heimese2ca4242008-01-03 20:23:15 +00003161
Christian Heimes0a8143f2007-12-18 23:22:54 +00003162- Issue #1635: Platform independent creation and representation of NaN
Georg Brandl3ee81df2008-05-17 18:14:43 +00003163 and INF. float("nan"), float("inf") and float("-inf") now work on
3164 every platform with IEEE 754 semantics.
Christian Heimes0a8143f2007-12-18 23:22:54 +00003165
Georg Brandl3ee81df2008-05-17 18:14:43 +00003166- Compiler now generates simpler and faster code for dictionary
3167 literals. The oparg for BUILD_MAP now indicates an estimated
3168 dictionary size. There is a new opcode, STORE_MAP, for adding
3169 entries to the dictionary.
Raymond Hettingerfd7ed402007-12-18 21:24:09 +00003170
Georg Brandl3ee81df2008-05-17 18:14:43 +00003171- Issue #1638: %zd configure test fails on Linux.

Andrew M. Kuchling395fe442007-12-05 13:27:20 +00003179- Issue #1553: An erroneous __length_hint__ can make list() raise a
Christian Heimes7cc1c6f2007-12-05 12:52:34 +00003180 SystemError.
3181
Nick Coghlanef01d822007-12-03 12:55:17 +00003182- PEP 366: Allow explicit relative imports when executing modules

3187 running, and if the deallocation of its frames somehow calls the
3188 PyGILState_Ensure() / PyGILState_Release() functions.
Amaury Forgeot d'Arcbe49a902007-11-30 20:37:22 +00003189

Amaury Forgeot d'Arcce7d10c2007-11-24 13:44:17 +00003193 attribute of an empty cell object.
3194
Georg Brandl3ee81df2008-05-17 18:14:43 +00003195- Issue #1460: The utf-7 incremental decoder did not accept truncated
3196 input. It now correctly saves its state between chunks of data.
Amaury Forgeot d'Arcf57375a2007-11-21 01:38:26 +00003197
Georg Brandl3ee81df2008-05-17 18:14:43 +00003198- Patch #1739468: Directories and zipfiles containing a __main__.py
3199 file can now be directly executed by passing their name to the
3200 interpreter. The directory/zipfile is automatically inserted as the
3201 first entry in sys.path.
Nick Coghlan327a39b2007-11-18 11:56:28 +00003202
Georg Brandl3ee81df2008-05-17 18:14:43 +00003203- Issue #1265: Fix a problem with sys.settrace, if the tracing
3204 function uses a generator expression when at the same time the
3205 executed code is closing a paused generator.
Amaury Forgeot d'Arc0d75f092007-11-13 21:54:28 +00003206
Raymond Hettinger1760c8a2007-11-08 02:52:43 +00003207- sets and frozensets now have an isdisjoint() method.
3208
Raymond Hettinger3f8caa32007-10-24 01:28:33 +00003209- optimize the performance of builtin.sum().
3210
Neal Norwitz44f326e2007-10-05 05:29:17 +00003211- Fix warnings found by the new version of the Coverity checker.
3212
Georg Brandl3ee81df2008-05-17 18:14:43 +00003213- The enumerate() builtin function is no longer bounded to sequences
3214 smaller than LONG_MAX. Formerly, it raised an OverflowError. Now,
3215 automatically shifts from ints to longs.
Raymond Hettinger8f669372007-10-03 21:18:11 +00003216
Georg Brandl3ee81df2008-05-17 18:14:43 +00003217- Issue #1686386: Tuple's tp_repr did not take into account the
3218 possibility of having a self-referential tuple, which is possible
3219 from C code. Nor did object's tp_str consider that a type's tp_str
3220 could do something that could lead to an inifinite recursion.
3221 Py_ReprEnter() and Py_EnterRecursiveCall(), respectively, fixed the
3222 issues.
Brett Cannon0b14f242007-09-30 19:45:10 +00003223
Georg Brandl3ee81df2008-05-17 18:14:43 +00003224- Issue #1164: It was possible to trigger deadlock when using the
3225 'print' statement to write to a file since the GIL was not released
3226 as needed. Now PyObject_Print() does the right thing along with
3227 various tp_print implementations of the built-in types and those in
3228 the collections module.
Brett Cannon01531592007-09-17 03:28:34 +00003229
Georg Brandl3ee81df2008-05-17 18:14:43 +00003230- Issue #1147: Exceptions were directly allowing string exceptions in
3231 their throw() method even though string exceptions no longer
3232 allowed.
Brett Cannon4c20bc42007-09-11 21:02:28 +00003233
Georg Brandl3ee81df2008-05-17 18:14:43 +00003234- Issue #1096: Prevent a segfault from getting the repr of a very
3235 deeply nested list by using the recursion counter.
Brett Cannona0c05512007-09-10 21:38:27 +00003236
Brett Cannon1e534b52007-09-07 04:18:30 +00003237- Issue #1202533: Fix infinite recursion calls triggered by calls to
Georg Brandl3ee81df2008-05-17 18:14:43 +00003238 PyObject_Call() never calling back out to Python code to trigger
3239 recursion depth updates/checks. Required the creation of a static
3240 RuntimeError instance in case normalizing an exception put the
3241 recursion check value past its limit. Fixes crashers
3242 infinite_rec_(1|2|4|5).py.
Brett Cannon1e534b52007-09-07 04:18:30 +00003243
Georg Brandl3ee81df2008-05-17 18:14:43 +00003244- Patch #1031213: Decode source line in SyntaxErrors back to its

3248 with %G.
3249
Georg Brandl3ee81df2008-05-17 18:14:43 +00003250- Prevent expandtabs() on string and unicode objects from causing a
3251 segfault when a large width is passed on 32-bit platforms.

Neal Norwitz0ac60192007-05-27 04:08:54 +00003257- Add new attribute names for function objects. All the func_* become
Georg Brandl3ee81df2008-05-17 18:14:43 +00003258 __*__ attributes. (Some already existed, e.g., __doc__ and
3259 __name__.)
Neal Norwitz0ac60192007-05-27 04:08:54 +00003260
Neal Norwitz8b2bfbc2007-05-23 06:35:32 +00003261- Add -3 option to the interpreter to warn about features that are
3262 deprecated and will be changed/removed in Python 3.0.
3263
Georg Brandl2134e752007-05-21 20:34:16 +00003264- Patch #1686487: you can now pass any mapping after '**' in function
3265 calls.
3266
Collin Winter62903052007-05-18 23:11:24 +00003267- except clauses may now be spelled either "except E, target:" or
Georg Brandl3ee81df2008-05-17 18:14:43 +00003268 "except E as target:". This is to provide forwards compatibility
3269 with Python 3.0.
Collin Winter62903052007-05-18 23:11:24 +00003270
Brett Cannon229cee22007-05-05 01:34:02 +00003271- Deprecate BaseException.message as per PEP 352.
3272
Georg Brandl3ee81df2008-05-17 18:14:43 +00003273- Issue #1303614: don't expose object's __dict__ when the dict is
Armin Rigo9790a272007-05-02 19:23:31 +00003274 inherited from a builtin base.
3275
Vinay Sajip8549ce32007-05-06 17:53:37 +00003276- When __slots__ are set to a unicode string, make it work the same as
Neal Norwitzcbd9ee62007-04-14 05:25:50 +00003277 setting a plain string, ie don't expand to single letter identifiers.
3278
Raymond Hettinger13936692007-04-11 18:40:58 +00003279- Request #1191699: Slices can now be pickled.
3280
Raymond Hettinger4db5fe92007-04-12 04:10:00 +00003281- Request #1193128: str.translate() now allows a None argument for
3282 translations that only remove characters without re-mapping the
3283 remaining characters.
3284
Georg Brandl5cb76c12007-03-21 09:00:39 +00003285- Patch #1682205: a TypeError while unpacking an iterable is no longer
3286 masked by a generic one with the message "unpack non-sequence".
3287
Neal Norwitzaa754b72007-03-21 06:39:48 +00003288- Remove unused file Python/fmod.c.
3289
Guido van Rossum143b5642007-03-23 04:58:42 +00003290- Bug #1683368: The object.__init__() and object.__new__() methods are
3291 now stricter in rejecting excess arguments. The only time when
3292 either allows excess arguments is when it is not overridden and the
3293 other one is. For backwards compatibility, when both are
3294 overridden, it is a deprecation warning (for now; maybe a Py3k
Guido van Rossum234b1ff2007-03-23 19:39:01 +00003295 warning later). Also, type.__init__() insists on the same signature
3296 as supported by type.__new__().
Guido van Rossum143b5642007-03-23 04:58:42 +00003297
Georg Brandl3ee81df2008-05-17 18:14:43 +00003298- Patch #1675423: PyComplex_AsCComplex() now tries to convert an
3299 object to complex using its __complex__() method before falling back
3300 to the __float__() method. Therefore, the functions in the cmath
3301 module now can operate on objects that define a __complex__()
3302 method.
Georg Brandl2b869942007-03-17 16:08:45 +00003303
Georg Brandl3ee81df2008-05-17 18:14:43 +00003304- Patch #1623563: allow __class__ assignment for classes with
3305 __slots__. The old and the new class are still required to have the
3306 same slot names.

3409 embedded in the string to convert.
3410

Georg Brandl3ee81df2008-05-17 18:14:43 +00003891 AttributeError instead of an IOError when the server's response
3892 didn't contain a valid HTTP status line.

Georg Brandl92a6bae2007-03-13 17:43:32 +00003925- Patch #1603688: ConfigParser.SafeConfigParser now checks values that
Georg Brandl3ee81df2008-05-17 18:14:43 +00003926 are set for invalid interpolation sequences that would lead to

3983 TestCase and TestSuite subclasses (not instances) are no longer

Georg Brandl3ee81df2008-05-17 18:14:43 +00004376 time so that opening a database previously created with the DB_DUP
4377 or DB_DUPSORT flag set will keep the proper behavior on subsequent
4378 opens. Specifically: dictionary assignment to a DB object will
4379 replace all values for a given key when the database allows
4380 duplicate values. DB users should use DB.put(k, v) when they want
4381 to store duplicates; not DB[k] = v.

4388 characters with ASCII value less than 32. Also, it correctly quotes
4389 dots only if they occur on a single line, as opposed to the previous
4390 behavior of quoting dots if they are the second character of any
4391 line.
Georg Brandl4aef7272007-03-13 22:49:43 +00004392
