884 in list_repeat (listobject.c) and islice_next (itertoolsmodule.c). These
885 bugs caused test failures with recent versions of Clang.

955 distutils.sysconfig and another copy in distutils.ccompiler, with some

Ned Deily0d0ea482012-02-10 12:59:06 +0100960- Issue #13590: On OS X 10.7 and 10.6 with Xcode 4.2, building
961 Distutils-based packages with C extension modules may fail because
962 Apple has removed gcc-4.2, the version used to build python.org
963 64-bit/32-bit Pythons. If the user does not explicitly override
964 the default C compiler by setting the CC environment variable,
965 Distutils will now attempt to compile extension modules with clang
966 if gcc-4.2 is required but not found. Also as a convenience, if
967 the user does explicitly set CC, substitute its value as the default
968 compiler in the Distutils LDSHARED configuration variable for OS X.
969 (Note, the python.org 32-bit-only Pythons use gcc-4.0 and the 10.4u
970 SDK, neither of which are available in Xcode 4. This change does not
971 attempt to override settings to support their use with Xcode 4.)

Ned Deily87e82bb2011-06-28 19:52:59 -07001244- Issue #9516: On Mac OS X, change Distutils to no longer globally attempt to
1245 check or set the MACOSX_DEPLOYMENT_TARGET environment variable for the
1246 interpreter process. This could cause failures in non-Distutils subprocesses
1247 and was unreliable since tests or user programs could modify the interpreter
Ezio Melotti302ad8d2013-01-19 19:44:58 +02001248 environment after Distutils set it. Instead, have Distutils set the
Ned Deily87e82bb2011-06-28 19:52:59 -07001249 deployment target only in the environment of each build subprocess. It is
1250 still possible to globally override the default by setting
1251 MACOSX_DEPLOYMENT_TARGET before launching the interpreter; its value must be
1252 greater or equal to the default value, the value with which the interpreter
1253 was built.

1280
Barry Warsawc5643282011-07-19 17:06:30 -04001281- sys.setcheckinterval() now updates the current ticker count as well as
1282 updating the check interval, so if the user decreases the check interval,
1283 the ticker doesn't have to wind down to zero from the old starting point
1284 before the new interval takes effect. And if the user increases the
1285 interval, it makes sure the new limit takes effect right away rather have an
1286 early task switch before recognizing the new interval.

Raymond Hettinger20397532010-09-12 02:11:45 +00002237- Issue #9825: removed __del__ from the definition of collections.OrderedDict.
2238 This prevents user-created self-referencing ordered dictionaries from
2239 becoming permanently uncollectable GC garbage. The downside is that
2240 removing __del__ means that the internal doubly-linked list has to wait for
2241 GC collection rather than freeing memory immediately when the refcnt drops
2242 to zero.

2250 to fetch the original errno, or to filter timeout errors. Now the
2251 original error is re-raised.

Ezio Melottiab2eb0e2010-06-05 19:21:32 +00002701- Issue #8271: during the decoding of an invalid UTF-8 byte sequence, only the
2702 start byte and the continuation byte(s) are now considered invalid, instead
2703 of the number of bytes specified by the start byte.
2704 E.g.: '\xf1\x80AB'.decode('utf-8', 'replace') now returns u'\ufffdAB' and
2705 replaces with U+FFFD only the start byte ('\xf1') and the continuation byte
2706 ('\x80') even if '\xf1' is the start byte of a 4-bytes sequence.

Mark Dickinson4ca7c3c2010-05-30 13:18:10 +00002715- Issue #8748: Fix two issues with comparisons between complex and integer
2716 objects. (1) The comparison could incorrectly return True in some cases
2717 (2**53+1 == complex(2**53) == 2**53), breaking transivity of equality.
2718 (2) The comparison raised an OverflowError for large integers, leading

Mark Dickinson81336372010-05-30 12:12:25 +00002722- Issue #5211: Implicit coercion for the complex type is now completely

3582 XML processing instructions and comments. These raw characters are allowed
3583 by the XML specification, and are necessary when outputting e.g. PHP code in
3584 a processing instruction. Patch by Neil Muller.

Antoine Pitroud840e512010-02-04 20:20:18 +00003592- Issue #4772: Raise a ValueError when an unknown Bluetooth protocol is
Georg Brandlba83f822010-03-14 09:50:54 +00003593 specified, rather than fall through to AF_PACKET (in the ``socket`` module).
Antoine Pitroud840e512010-02-04 20:20:18 +00003594 Also, raise ValueError rather than TypeError when an unknown TIPC address
3595 type is specified. Patch by Brian Curtin.
3596

Antoine Pitrouf3fa0742010-01-31 22:26:04 +00003599- Issue #6939: Fix file I/O objects in the `io` module to keep the original
Georg Brandlba83f822010-03-14 09:50:54 +00003600 file position when calling `truncate()`. It would previously change the file
3601 position to the given argument, which goes against the tradition of
Antoine Pitrouf3fa0742010-01-31 22:26:04 +00003602 ftruncate() and other truncation APIs. Patch by Pascal Chambon.
3603
Georg Brandlba83f822010-03-14 09:50:54 +00003604- Issue #7610: Reworked implementation of the internal ``zipfile.ZipExtFile``
3605 class used to represent files stored inside an archive. The new
3606 implementation is significantly faster and can be wrapped in a
3607 ``io.BufferedReader`` object for more speedups. It also solves an issue
3608 where interleaved calls to ``read()`` and ``readline()`` give wrong results.
3609 Patch by Nir Aides.

Georg Brandlba83f822010-03-14 09:50:54 +00003619- Issue #7748: Since unicode values are supported for some metadata options in
3620 Distutils, the DistributionMetadata get_* methods will now return an utf-8
3621 encoded string for them. This ensures that the upload and register commands
3622 send the correct values to PyPI without any error.

3697-----------------
3698
Georg Brandlba83f822010-03-14 09:50:54 +00003699- The ``__complex__()`` method is now looked up on the class of instances to
3700 make it consistent with other special methods.

Antoine Pitrou5b7139a2010-01-02 21:12:58 +00003702- Issue #7462: Implement the stringlib fast search algorithm for the `rfind`,
3703 `rindex`, `rsplit` and `rpartition` methods. Patch by Florent Xicluna.
3704
Mark Dickinson1b34d252010-01-01 17:27:30 +00003705- Issue #5080: A number of functions and methods previously produced a
Georg Brandlba83f822010-03-14 09:50:54 +00003706 DeprecationWarning when passed a float argument where an integer was expected.
3707 These functions and methods now raise TypeError instead. The majority of the
3708 effects of this change are in the extension modules, but some core functions
3709 and methods are affected: notably the 'chr', 'range' and 'xrange' builtins,
3710 and many unicode/str methods.

3724 of integers: the result of a/b is now correctly rounded for ints a and b (at
3725 least on IEEE 754 platforms), and in particular does not depend on the
3726 internal representation of a long.

Ronald Oussoren92919a62009-12-24 13:30:58 +00003733 executables on OSX.
3734
Georg Brandlba83f822010-03-14 09:50:54 +00003735 These executables now work properly with the arch(1) command: ``arch -ppc
3736 python`` will start a universal binary version of python in PPC mode (unlike
3737 previous releases).

Georg Brandlba83f822010-03-14 09:50:54 +00003760 renaming of `cPickle` to `pickle`. The warning was annoying since there's no

3877 to 'g' for large values.
Amaury Forgeot d'Arcd7288712009-12-01 21:51:04 +00003878

3880 1e50 in absolute value.

Ronald Oussoren315cd0c2009-11-19 16:25:21 +00003892
Georg Brandlba83f822010-03-14 09:50:54 +00003893- Issue #7117: ``repr(x)`` for a float x returns a result based on the shortest
3894 decimal string that's guaranteed to round back to x under correct rounding
3895 (with round-half-to-even rounding mode). Previously it gave a string based on
3896 rounding x to 17 decimal digits. repr(x) for a complex number behaves
3897 similarly. On platforms where the correctly-rounded strtod and dtoa code is
3898 not supported (see below), repr is unchanged.
Mark Dickinsonb678de82009-11-19 18:41:49 +00003899
Georg Brandlba83f822010-03-14 09:50:54 +00003900- Issue #7117: On almost all platforms: float-to-string and string-to-float
3901 conversions within Python are now correctly rounded. Places these conversions
3902 occur include: str for floats and complex numbers; the float and complex
3903 constructors; old-style and new-style numeric formatting; serialization and
3904 deserialization of floats and complex numbers using marshal, pickle and json;
3905 parsing of float and imaginary literals in Python code; Decimal-to-float
3906 conversion.
Mark Dickinsonb678de82009-11-19 18:41:49 +00003907
Georg Brandlba83f822010-03-14 09:50:54 +00003908 The conversions use a Python-adapted version of David Gay's well-known dtoa.c,
3909 providing correctly-rounded strtod and dtoa C functions. This code is
3910 supported on Windows, and on Unix-like platforms using gcc, icc or suncc as
3911 the C compiler. There may be a small number of platforms on which correct
3912 operation of this code cannot be guaranteed, so the code is not used: notably,
3913 this applies to platforms where the C double format is not IEEE 754 binary64,
3914 and to platforms on x86 hardware where the x87 FPU is set to 64-bit precision
3915 and Python's configure script is unable to determine how to change the FPU
3916 precision. On these platforms conversions use the platform strtod and dtoa,
3917 as before.
Mark Dickinsonb678de82009-11-19 18:41:49 +00003918
Georg Brandlba83f822010-03-14 09:50:54 +00003919- Issue #7117: Backport round implementation from Python 3.x. ``round()`` now
3920 uses the correctly-rounded string <-> float conversions described above (when
3921 available), and so produces correctly rounded results that will display nicely
3922 under the float repr. There are two related small changes: (1) round now
3923 accepts any class with an ``__index__()`` method for its second argument (but
3924 no longer accepts floats for the second argument), and (2) an excessively
3925 large second integer argument (e.g., ``round(1.234, 10**100)``) no longer
3926 raises an exception.

Mark Dickinsonb1d45852009-05-11 15:33:08 +00004068
Georg Brandlba83f822010-03-14 09:50:54 +00004069 (1) inf and nan strings with trailing whitespace were incorrectly rejected;
4070 (2) parsing of strings representing infinities and nans was locale aware; and
4071 (3) the interpretation of fromhex('-nan') didn't match that of float('-nan').

Georg Brandlba83f822010-03-14 09:50:54 +00004073- Issue #5920: For ``float.__format__()``, change the behavior with the empty
4074 presentation type (that is, not one of 'e', 'f', 'g', or 'n') to be like 'g'
4075 but with at least one decimal point and with a default precision
4076 of 12. Previously, the behavior the same but with a default precision of 6.
4077 This more closely matches ``str()``, and reduces surprises when adding
4078 alignment flags to the empty presentation type. This also affects the new
4079 complex.__format__ in the same way.
4080
4081- Issue #5890: In subclasses of 'property' the __doc__ attribute was shadowed by

Georg Brandlba83f822010-03-14 09:50:54 +00004277- Issue #4233: Changed semantic of ``_fileio.FileIO``'s ``close()`` method on
4278 file objects with closefd=False. The file descriptor is still kept open but
4279 the file object behaves like a closed file. The ``FileIO`` object also got a
4280 new readonly attribute ``closefd``.

4332 PyUnicode_DecodeUTF8() once, remember the result and output it in a second
4333 step. This avoids problems with counting UTF-8 bytes that ignores the effect

Walter Dörwald726ba8e2009-05-06 14:32:35 +00004336- Issue #3739: The unicode-internal encoder now reports the number of characters

Georg Brandlba83f822010-03-14 09:50:54 +00004339- Issue #2422: When compiled with the ``--with-valgrind`` option, the pymalloc

Martin v. Löwis9fa5a282008-09-11 06:53:30 +00005707- Issue #3642: Suppress warning in obmalloc when size_t is larger than uint.
5708
Amaury Forgeot d'Arc05e34492008-09-10 22:04:45 +00005709- Issue #3743: In a few places, PY_FORMAT_SIZE_T was incorrectly used with
5710 PyString_FromFormat or PyErr_Format to display size_t values. The macro
5711 PY_FORMAT_SIZE_T is designed to select the correct format for the OS
5712 ``printf`` function, whereas PyString_FromFormat has an independent
5713 implementation and uses "%zd" on all platforms for size_t values.
5714 This makes a difference on win64, where ``printf`` needs "%Id" to display
5715 64bit values.
5716
Benjamin Peterson97179b02008-09-09 20:55:01 +00005717- Issue #3634: _weakref.ref(Exception).__init__() gave invalid return value on
5718 error.
5719
Amaury Forgeot d'Arcd3ffb892008-09-09 07:24:30 +00005720- Issue #3777: long() applied to a float object now always return a long
5721 object; previously an int would be returned for small values. the __long__
5722 method is allowed to return either an int or a long, but the behaviour of
5723 float objects should not change to respect backward compatibility.
5724
Amaury Forgeot d'Arc3571fbf2008-09-01 19:52:00 +00005725- Issue #3751: str.rpartition would perform a left-partition when called with
5726 a unicode argument.

Vinay Sajip35e3b032008-09-01 14:33:59 +00005731 PyArg_ParseTuple and friends, which occurred when the argument for "s*"
Antoine Pitroud4ae97b2008-08-29 18:39:48 +00005732 was correctly parsed but parsing of subsequent arguments failed.
5733
Vinay Sajip35e3b032008-09-01 14:33:59 +00005734- Issue #2534: speed up isinstance() and issubclass() by 50-70%, so as to
Antoine Pitrou0668c622008-08-26 22:42:08 +00005735 match Python 2.5 speed despite the __instancecheck__ / __subclasscheck__
5736 mechanism. In the process, fix a bug where isinstance() and issubclass(),
5737 when given a tuple of classes as second argument, were looking up
5738 __instancecheck__ / __subclasscheck__ on the tuple rather than on each
5739 type object.
5740
Neal Norwitz18aa3882008-08-24 05:04:52 +00005741- Fix crashes on memory allocation failure found with failmalloc.

Brett Cannon1eaf0742008-09-02 01:25:16 +00005810 warnings.catch_warnings() along with some API cleanup. Expanding the tests
5811 for catch_warnings() also led to an improvement in the raising of a

5884-----------------
5885
Guido van Rossumf8402962008-08-20 15:01:50 +00005886- Issue #1878: Remove Py_TPFLAGS_HAVE_VERSION_TAG from
5887 Py_TPFLAGS_DEFAULT when not building the core. This means 3rd party
5888 extensions do not automatically benefit from the class attribute
5889 cache; they will have to explicitly add Py_TPFLAGS_HAVE_VERSION_TAG
5890 to their tp_flags field if they care. This is a backwards
5891 compatibility feature; in 3.0, all types will use the cache by
5892 default.
5893
Benjamin Petersonf647dc12008-08-20 01:27:30 +00005894- Keyword arguments can now follow starred arguments. (``f(a, *args,
5895 keyword=23)`` is now valid syntax.)
5896
Thomas Heller0ad5ae02008-08-19 19:25:04 +00005897- ctypes function pointers that are COM methods have a boolean True
5898 value again.
5899
Martin v. Löwisf91d46a2008-08-12 14:49:50 +00005900- Issue #3139: Make buffer-interface thread-safe wrt. PyArg_ParseTuple,
5901 by denying s# to parse objects that have a releasebuffer procedure,
5902 and introducing s*.
5903
Georg Brandl1e13ea92008-08-11 09:07:59 +00005904- Issue #3537: Fix an assertion failure when an empty but presized dict
5905 object was stored in the freelist.
5906
Mark Dickinsonb6467572008-08-04 21:30:09 +00005907- Issue #1481296: Make long(float('nan')) and int(float('nan')) raise
5908 ValueError consistently across platforms.
5909
Amaury Forgeot d'Arc39fd6722008-07-31 21:28:03 +00005910- Issue #3479: On platforms where sizeof(int) is smaller than sizeof(long)
5911 (64bit Unix, for example), unichr() would truncate its argument and return
5912 u'\x00' for unichr(2**32). Now it properly raises an OverflowError.
5913
Neal Norwitze7d8be82008-07-31 17:17:14 +00005914- Apply security patches from Apple.
5915
Amaury Forgeot d'Arc246daed2008-07-31 00:42:16 +00005916- Issue #2542: Now that issubclass() may call arbitrary code, ensure that
5917 PyErr_ExceptionMatches returns 0 when an exception occurs there.
5918
Antoine Pitrou92f82162008-07-25 22:22:08 +00005919- Issue #1819: function calls with several named parameters are now on
5920 average 35% faster (as measured by pybench).
5921
Amaury Forgeot d'Arce4921fe2008-07-21 22:00:38 +00005922- Issue #2378: An unexpected UnboundLocalError or NameError could appear when
5923 the python debugger steps into a class statement: the free variables (local
5924 variables defined in an outer scope) would be deleted from the outer scope.
5925
Gregory P. Smith0470bab2008-07-22 04:46:32 +00005926- Issue #2620: Overflow checking when allocating or reallocating memory
5927 was not always being done properly in some python types and extension
5928 modules. PyMem_MALLOC, PyMem_REALLOC, PyMem_NEW and PyMem_RESIZE have
5929 all been updated to perform better checks and places in the code that
5930 would previously leak memory on the error path when such an allocation
5931 failed have been fixed.

5937
Benjamin Petersone977ad42008-08-20 01:42:01 +00005938- The methods ``is_in_tuple()``, ``is_vararg()``, and ``is_keywordarg()`` of
5939 symtable.Symbol have been deprecated for removal in 3.0 and the next release.
5940
Amaury Forgeot d'Arc351ffb82008-08-18 19:23:47 +00005941- Issue #2234: distutils failed for some versions of the cygwin compiler. The
5942 version reported by these tools does not necessarily follow the python

5944
Nick Coghlanf70385a2008-08-18 12:42:46 +00005945- Issue #2235: Added Py3k warnings for types which will become unhashable
5946 under the stricter __hash__ inheritance rules in 3.0. Several types
5947 which did not meet the rules for hash invariants and were already
5948 unhashable in 3.0 have now been explicitly flagged as unhashable in
5949 2.6 as well (collections.Mapping, collections.Set, unittest.TestSuite,
5950 xml.dom.minidom.NamedNodeMap, numbers.Number, UserList.UserList)
5951

6007 the reload() built-in has been removed.
6008
Brett Cannon7e30b672008-08-04 21:52:25 +00006009- Changed code in the following modules/packages to remove warnings raised

Antoine Pitroude781a42008-08-09 12:43:23 +00006021 asking for a specific length. This problem only affected files opened
6022 using the new "io" module, not the built-in open() function.

6050
Gregory P. Smitha36f8fe2008-08-04 00:13:29 +00006051- Issue #1857: subprocess.Popen.poll gained an additional _deadstate keyword

6064 interaction with the tp_hash slot (added in 2.6b2) are now documented
6065
Nick Coghlan2a0c2b12008-08-04 12:47:17 +00006066- Issue #643841: The language reference now provides more detailed
6067 coverage of the lookup process for special methods. The disclaimers
6068 regarding lack of coverage of new-style classes have also been
6069 removed, since the coverage is now fairly reasonable.

6073================================
6074
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00006075*Release date: 17-Jul-2008*
6076
Raymond Hettingere3ae6552008-06-20 04:18:15 +00006077Core and Builtins
6078-----------------
6079
Georg Brandl3e483f62008-07-16 22:57:41 +00006080- Issue #3156: Fix inconsistent behavior of the bytearray type: all
6081 its methods now allow for items objects that can be converted to
6082 an integer using operator.index().
6083
Mark Dickinson64b7e502008-07-16 09:40:03 +00006084- Issue #3360: Fix incorrect parsing of '020000000000.0', which
6085 produced a ValueError instead of giving the correct float.
6086
Eric Smitha5fa5a22008-07-16 00:11:49 +00006087- Issue #3083: Add alternate (#) formatting for bin, oct, hex output
6088 for str.format(). This adds the prefix 0b, 0o, or 0x, respectively.
6089
Mark Dickinson7103aa42008-07-15 19:08:33 +00006090- Issue #3008: the float type has a new instance method 'float.hex'
6091 and a new class method 'float.fromhex' to convert floating-point
6092 numbers to and from hexadecimal strings, respectively.
6093
Nick Coghlan6d6bd442008-07-15 15:40:22 +00006094- Issue #2235: __hash__ is once again inherited by default. To allow
6095 collections.Hashable to remain meaningful in the presence of the
6096 default hash implementation (object.__hash__), it is now possible
6097 to explicit block inheritance of hash by setting __hash__=None at
6098 the Python level, or tp_hash=PyObject_HashNotImplemented at the C
6099 level.
6100
Nick Coghlanb028f502008-07-13 14:52:36 +00006101- Issue #3221: Issue a RuntimeWarning instead of raising SystemError if
6102 the parent module cannot be found while performing an absolute import.
6103 This means that an incorrectly defined __package__ attribute will
6104 now only prevent relative imports in that module rather than causing
6105 all imports from that module to fail.
6106
Nick Coghlan14ff9942008-07-08 14:21:42 +00006107- Issue #2517: Allow unicode messages in Exceptions again by correctly
6108 bypassing the instance dictionary when looking up __unicode__ on
6109 new-style classes.
6110
Amaury Forgeot d'Arcbdd941f2008-07-01 20:38:04 +00006111- Issue #3242: Fix a crash inside the print statement, if sys.stdout is
6112 set to a custom object whose write() method happens to install
6113 another file in sys.stdout.
6114
Amaury Forgeot d'Arc1f40c8a2008-06-30 22:42:40 +00006115- Issue #3088: Corrected a race condition in classes derived from
6116 threading.local: the first member set by a thread could be saved in
6117 another thread's dictionary.
6118
Mark Dickinson1ec2fcd2008-06-20 14:53:43 +00006119- Issue #3004: Minor change to slice.indices(): the start and stop
6120 arguments are now treated identically, making the behaviour easier
6121 to describe and understand. For example, slice(None, -10,
6122 1).indices(9) now returns (0, 0, 1) instead of (0, -1, 1), and
6123 slice(None, 10, -1).indices(10) returns (9, 9, -1) instead of (9,
6124 10, -1).
6125
Georg Brandl278fc502008-07-19 12:46:12 +00006126- Issue #3219: Calling a function with repeated keyword arguments,
6127 f(a=2, a=23), would not cause a syntax error. This was a regression
6128 from 2.4 caused by the switch to the new compiler.
Benjamin Peterson175e4d92008-07-01 19:34:52 +00006129
Georg Brandl278fc502008-07-19 12:46:12 +00006130- Issue #2862: Make int and float freelist management consistent with
6131 other freelists. Changes their CompactFreeList apis into
6132 ClearFreeList apis and calls them via gc.collect().

Thomas Heller57adf222008-08-14 19:10:48 +00006137- Issue #3554: ctypes.string_at and ctypes.wstring_at did call Python
6138 api functions without holding the GIL, which could lead to a fatal
6139 error when they failed.
6140
Martin v. Löwisaabf4042008-08-02 07:20:25 +00006141- Issue #799428: Fix Tkinter.Misc._nametowidget to unwrap Tcl command objects.

Amaury Forgeot d'Arc0f7cddc2008-07-06 21:34:39 +00006166- Issue #839496: SimpleHTTPServer used to open text files in text mode. This is
6167 both unnecessary (HTTP allows text content to be sent in several forms) and
Andrew M. Kuchlingcc3f2b12008-07-10 14:43:31 +00006168 wrong because the actual transmitted size could differ from the
Amaury Forgeot d'Arc0f7cddc2008-07-06 21:34:39 +00006169 content-length. The problem had been corrected in the 2.4 branch, but never
6170 merged into trunk.

Nick Coghlanc060b0e2008-07-02 13:09:19 +00006185- Issue #3190: Pydoc now hides the automatic module attribute __package__ (the

6187
Brett Cannon8bb8fa52008-07-02 01:57:08 +00006188- Issue #2885 (partial): The urllib.urlopen() function has been deprecated for

6577 mode or even as a 4-way universal binary (that is, PPC, i386,
Georg Brandl5cc774e2008-06-11 20:28:06 +00006578 PPC64 and x86_64 support in one binary).
Ronald Oussoren5640ce22008-06-05 12:58:24 +00006579
6580 This is controlled by the configure argument ``--with-universal-archs``:
6581
6582 - ``--with-universal-archs=all``: install 4-way universal
6583
6584 - ``--with-universal-archs=32-bit``: install 2-way universal, 32-bit (the default)
6585
6586 - ``--with-universal-archs=64-bit``: install 2-way universal, 64-bit
6587
6588 This option should be used in combination with ``--enable-universalsdk=``.
6589
6590 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 +00006640- Issue #1631171: Re-implement the 'warnings' module in C (the
6641 original Python code has been kept as backup). This will allow for
6642 using the 'warning's machinery in such places as the parser where
6643 use of pure Python code is not possible. Both the ``showarning()``
6644 and ``formatwarning()`` gain an optional 'line' argument which is
6645 not called by default for backwards-compatibility reasons. Setting
6646 ``warnings.showwarning()`` to an implementation that lacks support
6647 for the ``line`` argument will raise a DeprecationWarning.

Georg Brandl3ee81df2008-05-17 18:14:43 +00006689- Issue #2513: distutils on Windows is now capable of cross-compiling
Mark Hammond495cf992008-04-07 01:53:39 +00006690 extension modules between 32 and 64 bit platforms. See the distutls

Georg Brandl3ee81df2008-05-17 18:14:43 +00006710- Issue #2550: The approach used by client/server code for obtaining
6711 ports to listen on in network-oriented tests has been refined in an
6712 effort to facilitate running multiple instances of the entire
6713 regression test suite in parallel without issue.
6714 test_support.bind_port() has been fixed such that it will always
6715 return a unique port -- which wasn't always the case with the
6716 previous implementation, especially if socket options had been set
6717 that affected address reuse (i.e. SO_REUSEADDR, SO_REUSEPORT). The
6718 new implementation of bind_port() will actually raise an exception
6719 if it is passed an AF_INET/SOCK_STREAM socket with either the
6720 SO_REUSEADDR or SO_REUSEPORT socket option set. Furthermore, if
6721 available, bind_port() will set the SO_EXCLUSIVEADDRUSE option on
6722 the socket it's been passed. This currently only applies to
6723 Windows. This option prevents any other sockets from binding to the
6724 host/port we've bound to, thus removing the possibility of the
6725 'non-deterministic' behaviour, as Microsoft puts it, that occurs
6726 when a second SOCK_STREAM socket binds and accepts to a host/port
6727 that's already been bound by another socket. The optional preferred
6728 port parameter to bind_port() has been removed. Under no
6729 circumstances should tests be hard coding ports!
6730
6731 test_support.find_unused_port() has also been introduced, which will
6732 pass a temporary socket object to bind_port() in order to obtain an
6733 unused port. The temporary socket object is then closed and
6734 deleted, and the port is returned. This method should only be used
6735 for obtaining an unused port in order to pass to an external program
6736 (i.e. the -accept [port] argument to openssl's s_server mode) or as
6737 a parameter to a server-oriented class that doesn't give you direct
6738 access to the underlying socket used.
6739
6740 Finally, test_support.HOST has been introduced, which should be used
6741 for the host argument of any relevant socket calls (i.e. bind and
6742 connect).
Trent Nelsone41b0062008-04-08 23:47:30 +00006743
6744 The following tests were updated to following the new conventions:
Georg Brandl3ee81df2008-05-17 18:14:43 +00006745 test_socket, test_smtplib, test_asyncore, test_ssl, test_httplib,
Trent Nelsone41b0062008-04-08 23:47:30 +00006746 test_poplib, test_ftplib, test_telnetlib, test_socketserver,
6747 test_asynchat and test_socket_ssl.
6748
Georg Brandl3ee81df2008-05-17 18:14:43 +00006749 It is now possible for multiple instances of the regression test
6750 suite to run in parallel without issue.

Amaury Forgeot d'Arc9a0d3462008-03-23 09:55:29 +00006804- Issue #1477: With narrow Unicode builds, the unicode escape sequence
Georg Brandl3ee81df2008-05-17 18:14:43 +00006805 \Uxxxxxxxx did not accept values outside the Basic Multilingual
6806 Plane. This affected raw unicode literals and the
6807 'raw-unicode-escape' codec. Now UTF-16 surrogates are generated in
6808 this case, like normal unicode literals and the 'unicode-escape'
6809 codec.

7032 differ slightly in their output formats from the existing, unchanged
7033 Python 2.6 builtins. The expected usage of the future_builtins
7034 module is:
7035 from future_builtins import hex, oct
7036
Eric Smith7ef40bf2008-02-20 23:34:22 +00007037- Issue #1600: Modifed PyOS_ascii_formatd to use at most 2 digit
7038 exponents for exponents with absolute value < 100. Follows C99
7039 standard. This is a change on Windows, which would use 3 digits.
7040 Also, added 'n' to the formats that PyOS_ascii_formatd understands,
7041 so that any alterations it does to the resulting string will be
7042 available in stringlib/formatter.h (for float.__format__).
7043
Eric Smith5a3c1352008-02-19 13:21:56 +00007044- Implemented PEP 3101, Advanced String Formatting. This adds a new
7045 builtin format(); a format() method for str and unicode; a
7046 __format__() method to object, str, unicode, int, long, float, and
7047 datetime; the class string.Formatter; and the C API
7048 PyObject_Format().
7049
Georg Brandl3ee81df2008-05-17 18:14:43 +00007050- Fixed several potential crashes, all caused by specially crafted
7051 __del__ methods exploiting objects in temporarily inconsistent
7052 state.

Georg Brandl3ee81df2008-05-17 18:14:43 +00007061- Clear all free lists during a gc.collect() of the highest generation
7062 in order to allow pymalloc to free more arenas. Python may give back
7063 memory to the OS earlier.
Christian Heimes3b718a72008-02-14 12:47:33 +00007064
Georg Brandl3ee81df2008-05-17 18:14:43 +00007065- Issue #2045: Fix an infinite recursion triggered when printing a
7066 subclass of collections.defaultdict, if its default_factory is set
7067 to a bound method.

Georg Brandl3ee81df2008-05-17 18:14:43 +00007095- Patch #1473257: generator objects gain a gi_code attribute. This is
7096 the same object as the func_code attribute of the function that
7097 produced the generator.
Georg Brandl0cdf9a32008-01-26 14:14:20 +00007098
Georg Brandl3ee81df2008-05-17 18:14:43 +00007099- Issue #1920: "while 0" statements were completely removed by the
7100 compiler, even in the presence of an "else" clause, which is
7101 supposed to be run when the condition is false. Now the compiler
7102 correctly emits bytecode for the "else" suite.
Amaury Forgeot d'Arc31eaafe2008-01-24 22:59:25 +00007103
Guido van Rossumeead05f2008-01-24 18:21:02 +00007104- A few crashers fixed: weakref_in_del.py (issue #1377858);

7111
Georg Brandl3ee81df2008-05-17 18:14:43 +00007112- Issue #1915: Python compiles with --enable-unicode=no again. However
Christian Heimes082c9b02008-01-23 14:20:50 +00007113 several extension methods and modules do not work without unicode
7114 support.
7115

7120
Georg Brandl6caad7d2008-01-26 14:19:22 +00007121- Issue #1865: ``bytes`` as an alias for ``str`` and b"" as an alias "" were
Christian Heimes288e89a2008-01-18 18:24:07 +00007122 added.
7123
Christian Heimesc94e2b52008-01-14 04:13:37 +00007124- sys.float_info / PyFloat_GetInfo: The floating point information
7125 object was converted from a dict to a specialized structseq object.
7126
Georg Brandl3ee81df2008-05-17 18:14:43 +00007127- Patch #1816: Added sys.flags structseq. It exposes the status of
7128 most command line arguments and PYTHON* environment variables.
Christian Heimesf31b69f2008-01-14 03:42:48 +00007129
Georg Brandl3ee81df2008-05-17 18:14:43 +00007130- Objects/structseq.c: Implemented new structseq representation. The
7131 patch makes structseqs (e.g. the return value of os.stat) more
7132 readable.
Christian Heimes9c201962008-01-14 03:33:52 +00007133
Georg Brandl3ee81df2008-05-17 18:14:43 +00007134- Patch #1700288: added a type attribute cache that caches method
7135 accesses, resulting in speedups in heavily object-oriented code.
Amaury Forgeot d'Arce4c270c2008-01-14 00:29:41 +00007136
Neal Norwitz3fc15b82008-01-10 05:42:58 +00007137- Bug #1776: __import__() no longer accepts filenames on any platform.

7143 envvar and sys.dont_write_bytecode attribute. All these can be set
7144 to forbid Python to attempt to write compiled bytecode files.
Georg Brandl2da0fce2008-01-07 17:09:35 +00007145
Georg Brandl3ee81df2008-05-17 18:14:43 +00007146- Improve some exception messages when Windows fails to load an
7147 extension module. Now we get for example '%1 is not a valid Win32
7148 application' instead of 'error code 193'.

7205
Georg Brandl21e99f42010-03-07 15:23:59 +00007206- The enumerate() built-in function is no longer bounded to sequences
Georg Brandl3ee81df2008-05-17 18:14:43 +00007207 smaller than LONG_MAX. Formerly, it raised an OverflowError. Now,
7208 automatically shifts from ints to longs.
Raymond Hettinger8f669372007-10-03 21:18:11 +00007209
Georg Brandl3ee81df2008-05-17 18:14:43 +00007210- Issue #1686386: Tuple's tp_repr did not take into account the
7211 possibility of having a self-referential tuple, which is possible
7212 from C code. Nor did object's tp_str consider that a type's tp_str
7213 could do something that could lead to an inifinite recursion.
7214 Py_ReprEnter() and Py_EnterRecursiveCall(), respectively, fixed the
7215 issues.
Brett Cannon0b14f242007-09-30 19:45:10 +00007216
Georg Brandl3ee81df2008-05-17 18:14:43 +00007217- Issue #1164: It was possible to trigger deadlock when using the
7218 'print' statement to write to a file since the GIL was not released
7219 as needed. Now PyObject_Print() does the right thing along with
7220 various tp_print implementations of the built-in types and those in
7221 the collections module.
Brett Cannon01531592007-09-17 03:28:34 +00007222

Georg Brandl3ee81df2008-05-17 18:14:43 +00007231 PyObject_Call() never calling back out to Python code to trigger
7232 recursion depth updates/checks. Required the creation of a static
7233 RuntimeError instance in case normalizing an exception put the
7234 recursion check value past its limit. Fixes crashers

Raymond Hettinger4db5fe92007-04-12 04:10:00 +00007274- Request #1193128: str.translate() now allows a None argument for
7275 translations that only remove characters without re-mapping the
7276 remaining characters.
7277
Georg Brandl5cb76c12007-03-21 09:00:39 +00007278- Patch #1682205: a TypeError while unpacking an iterable is no longer
7279 masked by a generic one with the message "unpack non-sequence".

7282
Guido van Rossum143b5642007-03-23 04:58:42 +00007283- Bug #1683368: The object.__init__() and object.__new__() methods are
7284 now stricter in rejecting excess arguments. The only time when
7285 either allows excess arguments is when it is not overridden and the
7286 other one is. For backwards compatibility, when both are
7287 overridden, it is a deprecation warning (for now; maybe a Py3k
Guido van Rossum234b1ff2007-03-23 19:39:01 +00007288 warning later). Also, type.__init__() insists on the same signature
7289 as supported by type.__new__().

Georg Brandl3ee81df2008-05-17 18:14:43 +00007291- Patch #1675423: PyComplex_AsCComplex() now tries to convert an
7292 object to complex using its __complex__() method before falling back
7293 to the __float__() method. Therefore, the functions in the cmath
7294 module now can operate on objects that define a __complex__()
7295 method.

Georg Brandl7b9c5552007-03-12 14:30:05 +00007313- Bug #1678647: write a newline after printing an exception in any
7314 case, even when converting the value to a string failed.
7315
Georg Brandl871f1bc2007-03-12 13:17:36 +00007316- The dir() function has been extended to call the __dir__() method on
Georg Brandl3ee81df2008-05-17 18:14:43 +00007317 its argument, if it exists. If not, it will work like before. This
7318 allows customizing the output of dir() in the presence of a
7319 __getattr__().

7329 raising a ValueError.
Collin Wintere38051d2007-03-09 20:33:07 +00007330
Georg Brandlaa2321b2007-03-07 00:40:28 +00007331- Patch #703779: unset __file__ in __main__ after running a file. This
Georg Brandl3ee81df2008-05-17 18:14:43 +00007332 makes the filenames the warning module prints much more sensible
7333 when a PYTHONSTARTUP file is used.

7347 sq_ass_slice instead of the sq_slice slot.
7348
Georg Brandl3ee81df2008-05-17 18:14:43 +00007349- When printing an unraisable error, don't print exceptions. before

Georg Brandl2c1375c2006-10-12 11:27:59 +00007401- Bug #1545497: when given an explicit base, int() did ignore NULs
7402 embedded in the string to convert.
7403
Georg Brandl846f73a2006-10-08 07:11:54 +00007404- Bug #1569998: break inside a try statement (outside a loop) is now

Georg Brandl3ee81df2008-05-17 18:14:43 +00007452 generator expressions (x for x, in ... ) works again. Fixing this
7453 problem required changing the .pyc magic number. This means that
7454 .pyc files generated before 2.5c2 will be regenerated.

Georg Brandl3ee81df2008-05-17 18:14:43 +00007884 AttributeError instead of an IOError when the server's response
7885 didn't contain a valid HTTP status line.

7917
Georg Brandl92a6bae2007-03-13 17:43:32 +00007918- Patch #1603688: ConfigParser.SafeConfigParser now checks values that
Georg Brandl3ee81df2008-05-17 18:14:43 +00007919 are set for invalid interpolation sequences that would lead to

7976 TestCase and TestSuite subclasses (not instances) are no longer
7977 accepted in TestSuite.addTest(). This should cause no

7979 -- the failure just occurred later, with a more cumbersome
7980 exception.

8259 members).
Walter Dörwald84a3efe2007-06-13 16:57:12 +00008260
Georg Brandl3ee81df2008-05-17 18:14:43 +00008261- Issue #829951: In the smtplib module, SMTP.starttls() now complies
8262 with RFC 3207 and forgets any knowledge obtained from the server not
8263 obtained from the TLS negotiation itself. Patch contributed by Bill
8264 Fenner.
Gregory P. Smith2b3ba582008-01-17 08:03:17 +00008265
Georg Brandl3ee81df2008-05-17 18:14:43 +00008266- Issue #1339: The smtplib.SMTP class has been refactored a bit such
Gregory P. Smithbde4ae42008-01-17 08:35:49 +00008267 that the SMTP.starttls() caller no longer needs to call ehlo()
8268 beforehand. SMTP.starttls() now raises an exception of the server
Georg Brandl3ee81df2008-05-17 18:14:43 +00008269 does not claim to support starttls. Adds the
8270 SMTP.ehlo_or_helo_if_needed() method. Patch contributed by Bill
8271 Fenner.

8351 complex, tuple, list, dict, set, and frozenset. Formerly, it would
8352 silently miscode subclasses of those types. Now, it raises a
8353 ValueError instead.
Raymond Hettinger12e94202007-11-07 01:13:09 +00008354

Georg Brandl3ee81df2008-05-17 18:14:43 +00008369 time so that opening a database previously created with the DB_DUP
8370 or DB_DUPSORT flag set will keep the proper behavior on subsequent
8371 opens. Specifically: dictionary assignment to a DB object will
8372 replace all values for a given key when the database allows
8373 duplicate values. DB users should use DB.put(k, v) when they want
8374 to store duplicates; not DB[k] = v.
Gregory P. Smithec10a4a2007-11-05 02:32:26 +00008375

8381 characters with ASCII value less than 32. Also, it correctly quotes
8382 dots only if they occur on a single line, as opposed to the previous
8383 behavior of quoting dots if they are the second character of any
8384 line.
Georg Brandl4aef7272007-03-13 22:49:43 +00008385

Georg Brandl3ee81df2008-05-17 18:14:43 +00008790- Removed the macfs module. It had been deprecated since Python 2.5.
8791 This lead to the deprecation of macostools.touched() as it relied
8792 solely on macfs and was a no-op under OS X.
