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

Ned Deily0d0ea482012-02-10 12:59:06 +0100953- Issue #13590: On OS X 10.7 and 10.6 with Xcode 4.2, building
954 Distutils-based packages with C extension modules may fail because
955 Apple has removed gcc-4.2, the version used to build python.org
956 64-bit/32-bit Pythons. If the user does not explicitly override
957 the default C compiler by setting the CC environment variable,
958 Distutils will now attempt to compile extension modules with clang
959 if gcc-4.2 is required but not found. Also as a convenience, if
960 the user does explicitly set CC, substitute its value as the default
961 compiler in the Distutils LDSHARED configuration variable for OS X.
962 (Note, the python.org 32-bit-only Pythons use gcc-4.0 and the 10.4u
963 SDK, neither of which are available in Xcode 4. This change does not
964 attempt to override settings to support their use with Xcode 4.)

Ned Deily87e82bb2011-06-28 19:52:59 -07001237- Issue #9516: On Mac OS X, change Distutils to no longer globally attempt to
1238 check or set the MACOSX_DEPLOYMENT_TARGET environment variable for the
1239 interpreter process. This could cause failures in non-Distutils subprocesses
1240 and was unreliable since tests or user programs could modify the interpreter
Ezio Melotti302ad8d2013-01-19 19:44:58 +02001241 environment after Distutils set it. Instead, have Distutils set the
Ned Deily87e82bb2011-06-28 19:52:59 -07001242 deployment target only in the environment of each build subprocess. It is
1243 still possible to globally override the default by setting
1244 MACOSX_DEPLOYMENT_TARGET before launching the interpreter; its value must be
1245 greater or equal to the default value, the value with which the interpreter
1246 was built.

1276 the ticker doesn't have to wind down to zero from the old starting point
1277 before the new interval takes effect. And if the user increases the
1278 interval, it makes sure the new limit takes effect right away rather have an
1279 early task switch before recognizing the new interval.

2220 by Andrew Bennetts.

2229
Raymond Hettinger20397532010-09-12 02:11:45 +00002230- Issue #9825: removed __del__ from the definition of collections.OrderedDict.
2231 This prevents user-created self-referencing ordered dictionaries from
2232 becoming permanently uncollectable GC garbage. The downside is that
2233 removing __del__ means that the internal doubly-linked list has to wait for
2234 GC collection rather than freeing memory immediately when the refcnt drops
2235 to zero.
2236

2240
Antoine Pitrouc818ed42010-09-07 21:40:25 +00002241- Issue #9792: In case of connection failure, socket.create_connection()
2242 would swallow the exception and raise a new one, making it impossible
2243 to fetch the original errno, or to filter timeout errors. Now the
2244 original error is re-raised.
2245
Antoine Pitrouf4f61712010-09-07 16:34:47 +00002246- Issue #9758: When fcntl.ioctl() was called with mutable_flag set to True,

2248 be updated back after the system call. Original patch by Brian Brazil.

2265
R. David Murray7c4bf552010-08-25 01:45:57 +00002266- Issue #1194222: email.utils.parsedate now returns RFC2822 compliant four
2267 character years even if the message contains RFC822 two character years.
2268
Daniel Stutzbach91287322010-08-24 21:09:30 +00002269- Issue #8750: Fixed MutableSet's methods to correctly handle

2282
Antoine Pitrou3ebaed62010-08-21 19:17:25 +00002283- Issue #9617: Signals received during a low-level write operation aren't

2285
Benjamin Peterson52c36052010-08-21 03:03:22 +00002286- Issue #2521: Use weakrefs on for caching in the abc module, so that classes

2288
Raymond Hettingera54b2da2010-08-17 19:03:06 +00002289- Issue #9626: the view methods for collections.OrderedDict() were returning

2295 without this marker will not be overwritten or removed.
2296
Antoine Pitroue1436d12010-08-12 15:25:51 +00002297- Issue #7467: when reading a file from a ZIP archive, its CRC is checked

2299 case in Python 2.5 and earlier).
2300
Antoine Pitroucb4f47c2010-08-11 13:40:17 +00002301- Issue #9550: a BufferedReader could issue an additional read when the

2303 when the underlying raw IO channel was e.g. a socket. Report and original
2304 patch by Jason V. Miller.

2693
Ezio Melottiab2eb0e2010-06-05 19:21:32 +00002694- Issue #8271: during the decoding of an invalid UTF-8 byte sequence, only the
2695 start byte and the continuation byte(s) are now considered invalid, instead
2696 of the number of bytes specified by the start byte.
2697 E.g.: '\xf1\x80AB'.decode('utf-8', 'replace') now returns u'\ufffdAB' and
2698 replaces with U+FFFD only the start byte ('\xf1') and the continuation byte
2699 ('\x80') even if '\xf1' is the start byte of a 4-bytes sequence.
2700 Previous versions returned a single u'\ufffd'.

2704 arises from the "Overriding __eq__ blocks inheritance ..." warning
2705 when turned into an exception: in this case the exception simply
2706 gets ignored.

Mark Dickinson4ca7c3c2010-05-30 13:18:10 +00002708- Issue #8748: Fix two issues with comparisons between complex and integer
2709 objects. (1) The comparison could incorrectly return True in some cases
2710 (2**53+1 == complex(2**53) == 2**53), breaking transivity of equality.
2711 (2) The comparison raised an OverflowError for large integers, leading
2712 to unpredictable exceptions when combining integers and complex objects
2713 in sets or dicts.
2714
Mark Dickinson81336372010-05-30 12:12:25 +00002715- Issue #5211: Implicit coercion for the complex type is now completely
2716 removed. (Coercion for arithmetic operations was already removed in 2.7

Georg Brandlba83f822010-03-14 09:50:54 +00003593 file position when calling `truncate()`. It would previously change the file
3594 position to the given argument, which goes against the tradition of

3598 class used to represent files stored inside an archive. The new
3599 implementation is significantly faster and can be wrapped in a
3600 ``io.BufferedReader`` object for more speedups. It also solves an issue
3601 where interleaved calls to ``read()`` and ``readline()`` give wrong results.

Georg Brandlba83f822010-03-14 09:50:54 +00003692- The ``__complex__()`` method is now looked up on the class of instances to
3693 make it consistent with other special methods.

3697
Mark Dickinson1b34d252010-01-01 17:27:30 +00003698- Issue #5080: A number of functions and methods previously produced a
Georg Brandlba83f822010-03-14 09:50:54 +00003699 DeprecationWarning when passed a float argument where an integer was expected.
3700 These functions and methods now raise TypeError instead. The majority of the
3701 effects of this change are in the extension modules, but some core functions
3702 and methods are affected: notably the 'chr', 'range' and 'xrange' builtins,
3703 and many unicode/str methods.

3719 internal representation of a long.

3727
Georg Brandlba83f822010-03-14 09:50:54 +00003728 These executables now work properly with the arch(1) command: ``arch -ppc

Georg Brandlba83f822010-03-14 09:50:54 +00003815- Issue #5080: The argument parsing functions ``PyArg_ParseTuple()``,
3816 ``PyArg_ParseTupleAndKeywords()``, ``PyArg_VaParse()``,
3817 ``PyArg_VaParseTupleAndKeywords()`` and ``PyArg_Parse()`` no longer accept
3818 float arguments for integer format codes (other than 'L'): previously an
3819 attempt to pass a float resulted in a DeprecationWarning; now it gives a
3820 TypeError. For the 'L' format code (which previously had no warning) there is
3821 now a DeprecationWarning.

3869 upper case. This only affects 'inf' and 'nan', since 'f' no longer converts
3870 to 'g' for large values.
Amaury Forgeot d'Arcd7288712009-12-01 21:51:04 +00003871
Georg Brandlba83f822010-03-14 09:50:54 +00003872- Remove switch from "%f" formatting to "%g" formatting for floats larger than
3873 1e50 in absolute value.
Mark Dickinson9dd5e162009-11-23 20:54:09 +00003874
Georg Brandlba83f822010-03-14 09:50:54 +00003875- Remove restrictions on precision when formatting floats. E.g., "%.120g" %
3876 1e-100 used to raise OverflowError, but now gives the requested 120
3877 significant digits instead.

Ronald Oussoren315cd0c2009-11-19 16:25:21 +00003885
Georg Brandlba83f822010-03-14 09:50:54 +00003886- Issue #7117: ``repr(x)`` for a float x returns a result based on the shortest
3887 decimal string that's guaranteed to round back to x under correct rounding
3888 (with round-half-to-even rounding mode). Previously it gave a string based on
3889 rounding x to 17 decimal digits. repr(x) for a complex number behaves
3890 similarly. On platforms where the correctly-rounded strtod and dtoa code is
3891 not supported (see below), repr is unchanged.
Mark Dickinsonb678de82009-11-19 18:41:49 +00003892
Georg Brandlba83f822010-03-14 09:50:54 +00003893- Issue #7117: On almost all platforms: float-to-string and string-to-float
3894 conversions within Python are now correctly rounded. Places these conversions
3895 occur include: str for floats and complex numbers; the float and complex
3896 constructors; old-style and new-style numeric formatting; serialization and
3897 deserialization of floats and complex numbers using marshal, pickle and json;
3898 parsing of float and imaginary literals in Python code; Decimal-to-float
3899 conversion.
Mark Dickinsonb678de82009-11-19 18:41:49 +00003900
Georg Brandlba83f822010-03-14 09:50:54 +00003901 The conversions use a Python-adapted version of David Gay's well-known dtoa.c,
3902 providing correctly-rounded strtod and dtoa C functions. This code is
3903 supported on Windows, and on Unix-like platforms using gcc, icc or suncc as
3904 the C compiler. There may be a small number of platforms on which correct
3905 operation of this code cannot be guaranteed, so the code is not used: notably,
3906 this applies to platforms where the C double format is not IEEE 754 binary64,
3907 and to platforms on x86 hardware where the x87 FPU is set to 64-bit precision
3908 and Python's configure script is unable to determine how to change the FPU
3909 precision. On these platforms conversions use the platform strtod and dtoa,
3910 as before.
Mark Dickinsonb678de82009-11-19 18:41:49 +00003911
Georg Brandlba83f822010-03-14 09:50:54 +00003912- Issue #7117: Backport round implementation from Python 3.x. ``round()`` now
3913 uses the correctly-rounded string <-> float conversions described above (when
3914 available), and so produces correctly rounded results that will display nicely
3915 under the float repr. There are two related small changes: (1) round now
3916 accepts any class with an ``__index__()`` method for its second argument (but
3917 no longer accepts floats for the second argument), and (2) an excessively
3918 large second integer argument (e.g., ``round(1.234, 10**100)``) no longer
3919 raises an exception.

Mark Dickinsonb1d45852009-05-11 15:33:08 +00004061
Georg Brandlba83f822010-03-14 09:50:54 +00004062 (1) inf and nan strings with trailing whitespace were incorrectly rejected;
4063 (2) parsing of strings representing infinities and nans was locale aware; and
4064 (3) the interpretation of fromhex('-nan') didn't match that of float('-nan').

Georg Brandlba83f822010-03-14 09:50:54 +00004066- Issue #5920: For ``float.__format__()``, change the behavior with the empty
4067 presentation type (that is, not one of 'e', 'f', 'g', or 'n') to be like 'g'
4068 but with at least one decimal point and with a default precision
4069 of 12. Previously, the behavior the same but with a default precision of 6.
4070 This more closely matches ``str()``, and reduces surprises when adding
4071 alignment flags to the empty presentation type. This also affects the new
4072 complex.__format__ in the same way.
4073
4074- Issue #5890: In subclasses of 'property' the __doc__ attribute was shadowed by

5502 __long__ method could be packed by 'q', 'Q', '*q', '*Q'; for x with
5503 neither __int__ nor __long__, TypeError used to be raised (with a

Martin v. Löwis9fa5a282008-09-11 06:53:30 +00005700- Issue #3642: Suppress warning in obmalloc when size_t is larger than uint.
5701
Amaury Forgeot d'Arc05e34492008-09-10 22:04:45 +00005702- Issue #3743: In a few places, PY_FORMAT_SIZE_T was incorrectly used with
5703 PyString_FromFormat or PyErr_Format to display size_t values. The macro
5704 PY_FORMAT_SIZE_T is designed to select the correct format for the OS
5705 ``printf`` function, whereas PyString_FromFormat has an independent
5706 implementation and uses "%zd" on all platforms for size_t values.
5707 This makes a difference on win64, where ``printf`` needs "%Id" to display
5708 64bit values.
5709
Benjamin Peterson97179b02008-09-09 20:55:01 +00005710- Issue #3634: _weakref.ref(Exception).__init__() gave invalid return value on
5711 error.
5712
Amaury Forgeot d'Arcd3ffb892008-09-09 07:24:30 +00005713- Issue #3777: long() applied to a float object now always return a long
5714 object; previously an int would be returned for small values. the __long__
5715 method is allowed to return either an int or a long, but the behaviour of
5716 float objects should not change to respect backward compatibility.
5717
Amaury Forgeot d'Arc3571fbf2008-09-01 19:52:00 +00005718- Issue #3751: str.rpartition would perform a left-partition when called with
5719 a unicode argument.

Vinay Sajip35e3b032008-09-01 14:33:59 +00005724 PyArg_ParseTuple and friends, which occurred when the argument for "s*"
Antoine Pitroud4ae97b2008-08-29 18:39:48 +00005725 was correctly parsed but parsing of subsequent arguments failed.
5726
Vinay Sajip35e3b032008-09-01 14:33:59 +00005727- Issue #2534: speed up isinstance() and issubclass() by 50-70%, so as to
Antoine Pitrou0668c622008-08-26 22:42:08 +00005728 match Python 2.5 speed despite the __instancecheck__ / __subclasscheck__
5729 mechanism. In the process, fix a bug where isinstance() and issubclass(),
5730 when given a tuple of classes as second argument, were looking up
5731 __instancecheck__ / __subclasscheck__ on the tuple rather than on each
5732 type object.
5733
Neal Norwitz18aa3882008-08-24 05:04:52 +00005734- Fix crashes on memory allocation failure found with failmalloc.

Brett Cannon1eaf0742008-09-02 01:25:16 +00005803 warnings.catch_warnings() along with some API cleanup. Expanding the tests
5804 for catch_warnings() also led to an improvement in the raising of a
5805 DeprecationWarning related to warnings.warn_explicit().

5877-----------------
5878
Guido van Rossumf8402962008-08-20 15:01:50 +00005879- Issue #1878: Remove Py_TPFLAGS_HAVE_VERSION_TAG from
5880 Py_TPFLAGS_DEFAULT when not building the core. This means 3rd party
5881 extensions do not automatically benefit from the class attribute
5882 cache; they will have to explicitly add Py_TPFLAGS_HAVE_VERSION_TAG
5883 to their tp_flags field if they care. This is a backwards
5884 compatibility feature; in 3.0, all types will use the cache by
5885 default.
5886
Benjamin Petersonf647dc12008-08-20 01:27:30 +00005887- Keyword arguments can now follow starred arguments. (``f(a, *args,
5888 keyword=23)`` is now valid syntax.)
5889
Thomas Heller0ad5ae02008-08-19 19:25:04 +00005890- ctypes function pointers that are COM methods have a boolean True
5891 value again.
5892
Martin v. Löwisf91d46a2008-08-12 14:49:50 +00005893- Issue #3139: Make buffer-interface thread-safe wrt. PyArg_ParseTuple,
5894 by denying s# to parse objects that have a releasebuffer procedure,
5895 and introducing s*.
5896
Georg Brandl1e13ea92008-08-11 09:07:59 +00005897- Issue #3537: Fix an assertion failure when an empty but presized dict
5898 object was stored in the freelist.
5899
Mark Dickinsonb6467572008-08-04 21:30:09 +00005900- Issue #1481296: Make long(float('nan')) and int(float('nan')) raise
5901 ValueError consistently across platforms.
5902
Amaury Forgeot d'Arc39fd6722008-07-31 21:28:03 +00005903- Issue #3479: On platforms where sizeof(int) is smaller than sizeof(long)
5904 (64bit Unix, for example), unichr() would truncate its argument and return
5905 u'\x00' for unichr(2**32). Now it properly raises an OverflowError.
5906
Neal Norwitze7d8be82008-07-31 17:17:14 +00005907- Apply security patches from Apple.
5908
Amaury Forgeot d'Arc246daed2008-07-31 00:42:16 +00005909- Issue #2542: Now that issubclass() may call arbitrary code, ensure that
5910 PyErr_ExceptionMatches returns 0 when an exception occurs there.
5911
Antoine Pitrou92f82162008-07-25 22:22:08 +00005912- Issue #1819: function calls with several named parameters are now on
5913 average 35% faster (as measured by pybench).
5914
Amaury Forgeot d'Arce4921fe2008-07-21 22:00:38 +00005915- Issue #2378: An unexpected UnboundLocalError or NameError could appear when
5916 the python debugger steps into a class statement: the free variables (local
5917 variables defined in an outer scope) would be deleted from the outer scope.
5918
Gregory P. Smith0470bab2008-07-22 04:46:32 +00005919- Issue #2620: Overflow checking when allocating or reallocating memory
5920 was not always being done properly in some python types and extension
5921 modules. PyMem_MALLOC, PyMem_REALLOC, PyMem_NEW and PyMem_RESIZE have
5922 all been updated to perform better checks and places in the code that
5923 would previously leak memory on the error path when such an allocation
5924 failed have been fixed.

5930
Benjamin Petersone977ad42008-08-20 01:42:01 +00005931- The methods ``is_in_tuple()``, ``is_vararg()``, and ``is_keywordarg()`` of
5932 symtable.Symbol have been deprecated for removal in 3.0 and the next release.
5933
Amaury Forgeot d'Arc351ffb82008-08-18 19:23:47 +00005934- Issue #2234: distutils failed for some versions of the cygwin compiler. The
5935 version reported by these tools does not necessarily follow the python
5936 version numbering scheme, so the module is less strict when parsing it.
5937
Nick Coghlanf70385a2008-08-18 12:42:46 +00005938- Issue #2235: Added Py3k warnings for types which will become unhashable
5939 under the stricter __hash__ inheritance rules in 3.0. Several types

Antoine Pitroude781a42008-08-09 12:43:23 +00006014 asking for a specific length. This problem only affected files opened

6057 interaction with the tp_hash slot (added in 2.6b2) are now documented
6058
Nick Coghlan2a0c2b12008-08-04 12:47:17 +00006059- Issue #643841: The language reference now provides more detailed

6066================================
6067
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00006068*Release date: 17-Jul-2008*
6069
Raymond Hettingere3ae6552008-06-20 04:18:15 +00006070Core and Builtins
6071-----------------
6072
Georg Brandl3e483f62008-07-16 22:57:41 +00006073- Issue #3156: Fix inconsistent behavior of the bytearray type: all
6074 its methods now allow for items objects that can be converted to
6075 an integer using operator.index().
6076
Mark Dickinson64b7e502008-07-16 09:40:03 +00006077- Issue #3360: Fix incorrect parsing of '020000000000.0', which
6078 produced a ValueError instead of giving the correct float.
6079
Eric Smitha5fa5a22008-07-16 00:11:49 +00006080- Issue #3083: Add alternate (#) formatting for bin, oct, hex output
6081 for str.format(). This adds the prefix 0b, 0o, or 0x, respectively.
6082
Mark Dickinson7103aa42008-07-15 19:08:33 +00006083- Issue #3008: the float type has a new instance method 'float.hex'
6084 and a new class method 'float.fromhex' to convert floating-point
6085 numbers to and from hexadecimal strings, respectively.
6086
Nick Coghlan6d6bd442008-07-15 15:40:22 +00006087- Issue #2235: __hash__ is once again inherited by default. To allow
6088 collections.Hashable to remain meaningful in the presence of the
6089 default hash implementation (object.__hash__), it is now possible
6090 to explicit block inheritance of hash by setting __hash__=None at
6091 the Python level, or tp_hash=PyObject_HashNotImplemented at the C
6092 level.
6093
Nick Coghlanb028f502008-07-13 14:52:36 +00006094- Issue #3221: Issue a RuntimeWarning instead of raising SystemError if
6095 the parent module cannot be found while performing an absolute import.
6096 This means that an incorrectly defined __package__ attribute will
6097 now only prevent relative imports in that module rather than causing
6098 all imports from that module to fail.
6099
Nick Coghlan14ff9942008-07-08 14:21:42 +00006100- Issue #2517: Allow unicode messages in Exceptions again by correctly
6101 bypassing the instance dictionary when looking up __unicode__ on
6102 new-style classes.
6103
Amaury Forgeot d'Arcbdd941f2008-07-01 20:38:04 +00006104- Issue #3242: Fix a crash inside the print statement, if sys.stdout is
6105 set to a custom object whose write() method happens to install
6106 another file in sys.stdout.
6107
Amaury Forgeot d'Arc1f40c8a2008-06-30 22:42:40 +00006108- Issue #3088: Corrected a race condition in classes derived from
6109 threading.local: the first member set by a thread could be saved in
6110 another thread's dictionary.
6111
Mark Dickinson1ec2fcd2008-06-20 14:53:43 +00006112- Issue #3004: Minor change to slice.indices(): the start and stop
6113 arguments are now treated identically, making the behaviour easier
6114 to describe and understand. For example, slice(None, -10,
6115 1).indices(9) now returns (0, 0, 1) instead of (0, -1, 1), and
6116 slice(None, 10, -1).indices(10) returns (9, 9, -1) instead of (9,
6117 10, -1).
6118
Georg Brandl278fc502008-07-19 12:46:12 +00006119- Issue #3219: Calling a function with repeated keyword arguments,
6120 f(a=2, a=23), would not cause a syntax error. This was a regression
6121 from 2.4 caused by the switch to the new compiler.
Benjamin Peterson175e4d92008-07-01 19:34:52 +00006122
Georg Brandl278fc502008-07-19 12:46:12 +00006123- Issue #2862: Make int and float freelist management consistent with
6124 other freelists. Changes their CompactFreeList apis into
6125 ClearFreeList apis and calls them via gc.collect().

6131 api functions without holding the GIL, which could lead to a fatal
6132 error when they failed.
6133
Martin v. Löwisaabf4042008-08-02 07:20:25 +00006134- Issue #799428: Fix Tkinter.Misc._nametowidget to unwrap Tcl command objects.

Amaury Forgeot d'Arc0f7cddc2008-07-06 21:34:39 +00006159- Issue #839496: SimpleHTTPServer used to open text files in text mode. This is
6160 both unnecessary (HTTP allows text content to be sent in several forms) and
Andrew M. Kuchlingcc3f2b12008-07-10 14:43:31 +00006161 wrong because the actual transmitted size could differ from the
Amaury Forgeot d'Arc0f7cddc2008-07-06 21:34:39 +00006162 content-length. The problem had been corrected in the 2.4 branch, but never
6163 merged into trunk.

Nick Coghlanc060b0e2008-07-02 13:09:19 +00006178- Issue #3190: Pydoc now hides the automatic module attribute __package__ (the

Ronald Oussoren5640ce22008-06-05 12:58:24 +00006569- On MacOS X it is now possible to install the framework in 64-bit
6570 mode or even as a 4-way universal binary (that is, PPC, i386,
Georg Brandl5cc774e2008-06-11 20:28:06 +00006571 PPC64 and x86_64 support in one binary).
Ronald Oussoren5640ce22008-06-05 12:58:24 +00006572
6573 This is controlled by the configure argument ``--with-universal-archs``:
6574
6575 - ``--with-universal-archs=all``: install 4-way universal
6576
6577 - ``--with-universal-archs=32-bit``: install 2-way universal, 32-bit (the default)
6578
6579 - ``--with-universal-archs=64-bit``: install 2-way universal, 64-bit
6580
6581 This option should be used in combination with ``--enable-universalsdk=``.
6582
6583 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 +00006633- Issue #1631171: Re-implement the 'warnings' module in C (the
6634 original Python code has been kept as backup). This will allow for
6635 using the 'warning's machinery in such places as the parser where
6636 use of pure Python code is not possible. Both the ``showarning()``
6637 and ``formatwarning()`` gain an optional 'line' argument which is
6638 not called by default for backwards-compatibility reasons. Setting
6639 ``warnings.showwarning()`` to an implementation that lacks support
6640 for the ``line`` argument will raise a DeprecationWarning.

Georg Brandl3ee81df2008-05-17 18:14:43 +00006703- Issue #2550: The approach used by client/server code for obtaining
6704 ports to listen on in network-oriented tests has been refined in an
6705 effort to facilitate running multiple instances of the entire
6706 regression test suite in parallel without issue.
6707 test_support.bind_port() has been fixed such that it will always
6708 return a unique port -- which wasn't always the case with the
6709 previous implementation, especially if socket options had been set
6710 that affected address reuse (i.e. SO_REUSEADDR, SO_REUSEPORT). The
6711 new implementation of bind_port() will actually raise an exception
6712 if it is passed an AF_INET/SOCK_STREAM socket with either the
6713 SO_REUSEADDR or SO_REUSEPORT socket option set. Furthermore, if
6714 available, bind_port() will set the SO_EXCLUSIVEADDRUSE option on
6715 the socket it's been passed. This currently only applies to
6716 Windows. This option prevents any other sockets from binding to the
6717 host/port we've bound to, thus removing the possibility of the
6718 'non-deterministic' behaviour, as Microsoft puts it, that occurs
6719 when a second SOCK_STREAM socket binds and accepts to a host/port
6720 that's already been bound by another socket. The optional preferred
6721 port parameter to bind_port() has been removed. Under no
6722 circumstances should tests be hard coding ports!
6723
6724 test_support.find_unused_port() has also been introduced, which will
6725 pass a temporary socket object to bind_port() in order to obtain an
6726 unused port. The temporary socket object is then closed and
6727 deleted, and the port is returned. This method should only be used
6728 for obtaining an unused port in order to pass to an external program
6729 (i.e. the -accept [port] argument to openssl's s_server mode) or as
6730 a parameter to a server-oriented class that doesn't give you direct
6731 access to the underlying socket used.
6732
6733 Finally, test_support.HOST has been introduced, which should be used
6734 for the host argument of any relevant socket calls (i.e. bind and
6735 connect).
Trent Nelsone41b0062008-04-08 23:47:30 +00006736
6737 The following tests were updated to following the new conventions:
Georg Brandl3ee81df2008-05-17 18:14:43 +00006738 test_socket, test_smtplib, test_asyncore, test_ssl, test_httplib,
Trent Nelsone41b0062008-04-08 23:47:30 +00006739 test_poplib, test_ftplib, test_telnetlib, test_socketserver,
6740 test_asynchat and test_socket_ssl.
6741
Georg Brandl3ee81df2008-05-17 18:14:43 +00006742 It is now possible for multiple instances of the regression test
6743 suite to run in parallel without issue.

Amaury Forgeot d'Arc9a0d3462008-03-23 09:55:29 +00006797- Issue #1477: With narrow Unicode builds, the unicode escape sequence
Georg Brandl3ee81df2008-05-17 18:14:43 +00006798 \Uxxxxxxxx did not accept values outside the Basic Multilingual
6799 Plane. This affected raw unicode literals and the
6800 'raw-unicode-escape' codec. Now UTF-16 surrogates are generated in
6801 this case, like normal unicode literals and the 'unicode-escape'
6802 codec.

Eric Smitha73fbe72008-02-23 03:09:44 +00007022- Added the future_builtins module, which contains hex() and oct().
7023 These are the PEP 3127 version of these functions, designed to be
7024 compatible with the hex() and oct() builtins from Python 3.0. They
7025 differ slightly in their output formats from the existing, unchanged
7026 Python 2.6 builtins. The expected usage of the future_builtins
7027 module is:

7029
Eric Smith7ef40bf2008-02-20 23:34:22 +00007030- Issue #1600: Modifed PyOS_ascii_formatd to use at most 2 digit
7031 exponents for exponents with absolute value < 100. Follows C99
7032 standard. This is a change on Windows, which would use 3 digits.
7033 Also, added 'n' to the formats that PyOS_ascii_formatd understands,
7034 so that any alterations it does to the resulting string will be
7035 available in stringlib/formatter.h (for float.__format__).
7036
Eric Smith5a3c1352008-02-19 13:21:56 +00007037- Implemented PEP 3101, Advanced String Formatting. This adds a new
7038 builtin format(); a format() method for str and unicode; a
7039 __format__() method to object, str, unicode, int, long, float, and
7040 datetime; the class string.Formatter; and the C API
7041 PyObject_Format().
7042
Georg Brandl3ee81df2008-05-17 18:14:43 +00007043- Fixed several potential crashes, all caused by specially crafted
7044 __del__ methods exploiting objects in temporarily inconsistent
7045 state.
Amaury Forgeot d'Arc632fad32008-02-16 20:55:24 +00007046
Vinay Sajipb7edfc42008-04-02 21:10:23 +00007047- Issue #2115: Important speedup in setting __slot__ attributes. Also
Georg Brandl3ee81df2008-05-17 18:14:43 +00007048 prevent a possible crash: an Abstract Base Class would try to access
7049 a slot on a registered virtual subclass.
Amaury Forgeot d'Arc60d6c7f2008-02-15 21:22:45 +00007050

Georg Brandl3ee81df2008-05-17 18:14:43 +00007054- Clear all free lists during a gc.collect() of the highest generation
7055 in order to allow pymalloc to free more arenas. Python may give back
7056 memory to the OS earlier.
Christian Heimes3b718a72008-02-14 12:47:33 +00007057
Georg Brandl3ee81df2008-05-17 18:14:43 +00007058- Issue #2045: Fix an infinite recursion triggered when printing a
7059 subclass of collections.defaultdict, if its default_factory is set
7060 to a bound method.

Georg Brandl3ee81df2008-05-17 18:14:43 +00007088- Patch #1473257: generator objects gain a gi_code attribute. This is
7089 the same object as the func_code attribute of the function that
7090 produced the generator.
Georg Brandl0cdf9a32008-01-26 14:14:20 +00007091
Georg Brandl3ee81df2008-05-17 18:14:43 +00007092- Issue #1920: "while 0" statements were completely removed by the
7093 compiler, even in the presence of an "else" clause, which is
7094 supposed to be run when the condition is false. Now the compiler
7095 correctly emits bytecode for the "else" suite.
Amaury Forgeot d'Arc31eaafe2008-01-24 22:59:25 +00007096
Guido van Rossumeead05f2008-01-24 18:21:02 +00007097- A few crashers fixed: weakref_in_del.py (issue #1377858);
7098 loosing_dict_ref.py (issue #1303614, test67.py);
7099 borrowed_ref_[34].py (not in tracker).
7100
Vinay Sajipd7cf32e2008-01-24 12:43:33 +00007101- Issue #1069410: The "can't load dll" message box on Windows is
Christian Heimesb2302ba2008-01-23 17:15:06 +00007102 suppressed while an extension is loaded by calling SetErrorMode in

7104
Georg Brandl3ee81df2008-05-17 18:14:43 +00007105- Issue #1915: Python compiles with --enable-unicode=no again. However
Christian Heimes082c9b02008-01-23 14:20:50 +00007106 several extension methods and modules do not work without unicode
7107 support.
7108
Georg Brandl26543b12008-01-21 18:36:51 +00007109- Issue #1882: when compiling code from a string, encoding cookies in the

7113
Georg Brandl6caad7d2008-01-26 14:19:22 +00007114- Issue #1865: ``bytes`` as an alias for ``str`` and b"" as an alias "" were
Christian Heimes288e89a2008-01-18 18:24:07 +00007115 added.
7116
Christian Heimesc94e2b52008-01-14 04:13:37 +00007117- sys.float_info / PyFloat_GetInfo: The floating point information
7118 object was converted from a dict to a specialized structseq object.
7119
Georg Brandl3ee81df2008-05-17 18:14:43 +00007120- Patch #1816: Added sys.flags structseq. It exposes the status of
7121 most command line arguments and PYTHON* environment variables.
Christian Heimesf31b69f2008-01-14 03:42:48 +00007122
Georg Brandl3ee81df2008-05-17 18:14:43 +00007123- Objects/structseq.c: Implemented new structseq representation. The
7124 patch makes structseqs (e.g. the return value of os.stat) more
7125 readable.
Christian Heimes9c201962008-01-14 03:33:52 +00007126
Georg Brandl3ee81df2008-05-17 18:14:43 +00007127- Patch #1700288: added a type attribute cache that caches method
7128 accesses, resulting in speedups in heavily object-oriented code.
Amaury Forgeot d'Arce4c270c2008-01-14 00:29:41 +00007129
Neal Norwitz3fc15b82008-01-10 05:42:58 +00007130- Bug #1776: __import__() no longer accepts filenames on any platform.

7136 envvar and sys.dont_write_bytecode attribute. All these can be set
7137 to forbid Python to attempt to write compiled bytecode files.
Georg Brandl2da0fce2008-01-07 17:09:35 +00007138
Georg Brandl3ee81df2008-05-17 18:14:43 +00007139- Improve some exception messages when Windows fails to load an
7140 extension module. Now we get for example '%1 is not a valid Win32
7141 application' instead of 'error code 193'.

7198
Georg Brandl21e99f42010-03-07 15:23:59 +00007199- The enumerate() built-in function is no longer bounded to sequences
Georg Brandl3ee81df2008-05-17 18:14:43 +00007200 smaller than LONG_MAX. Formerly, it raised an OverflowError. Now,
7201 automatically shifts from ints to longs.
Raymond Hettinger8f669372007-10-03 21:18:11 +00007202
Georg Brandl3ee81df2008-05-17 18:14:43 +00007203- Issue #1686386: Tuple's tp_repr did not take into account the
7204 possibility of having a self-referential tuple, which is possible
7205 from C code. Nor did object's tp_str consider that a type's tp_str
7206 could do something that could lead to an inifinite recursion.
7207 Py_ReprEnter() and Py_EnterRecursiveCall(), respectively, fixed the
7208 issues.
Brett Cannon0b14f242007-09-30 19:45:10 +00007209
Georg Brandl3ee81df2008-05-17 18:14:43 +00007210- Issue #1164: It was possible to trigger deadlock when using the
7211 'print' statement to write to a file since the GIL was not released
7212 as needed. Now PyObject_Print() does the right thing along with
7213 various tp_print implementations of the built-in types and those in
7214 the collections module.
Brett Cannon01531592007-09-17 03:28:34 +00007215
Georg Brandl3ee81df2008-05-17 18:14:43 +00007216- Issue #1147: Exceptions were directly allowing string exceptions in

Georg Brandl3ee81df2008-05-17 18:14:43 +00007224 PyObject_Call() never calling back out to Python code to trigger
7225 recursion depth updates/checks. Required the creation of a static
7226 RuntimeError instance in case normalizing an exception put the
7227 recursion check value past its limit. Fixes crashers

Georg Brandl5cb76c12007-03-21 09:00:39 +00007271- Patch #1682205: a TypeError while unpacking an iterable is no longer
7272 masked by a generic one with the message "unpack non-sequence".

Guido van Rossum143b5642007-03-23 04:58:42 +00007276- Bug #1683368: The object.__init__() and object.__new__() methods are
7277 now stricter in rejecting excess arguments. The only time when
7278 either allows excess arguments is when it is not overridden and the
7279 other one is. For backwards compatibility, when both are
7280 overridden, it is a deprecation warning (for now; maybe a Py3k
Guido van Rossum234b1ff2007-03-23 19:39:01 +00007281 warning later). Also, type.__init__() insists on the same signature
7282 as supported by type.__new__().

Georg Brandl3ee81df2008-05-17 18:14:43 +00007284- Patch #1675423: PyComplex_AsCComplex() now tries to convert an
7285 object to complex using its __complex__() method before falling back
7286 to the __float__() method. Therefore, the functions in the cmath
7287 module now can operate on objects that define a __complex__()
7288 method.

Georg Brandl7b9c5552007-03-12 14:30:05 +00007306- Bug #1678647: write a newline after printing an exception in any
7307 case, even when converting the value to a string failed.
7308
Georg Brandl871f1bc2007-03-12 13:17:36 +00007309- The dir() function has been extended to call the __dir__() method on
Georg Brandl3ee81df2008-05-17 18:14:43 +00007310 its argument, if it exists. If not, it will work like before. This
7311 allows customizing the output of dir() in the presence of a
7312 __getattr__().

7322 raising a ValueError.

Georg Brandlaa2321b2007-03-07 00:40:28 +00007324- Patch #703779: unset __file__ in __main__ after running a file. This
Georg Brandl3ee81df2008-05-17 18:14:43 +00007325 makes the filenames the warning module prints much more sensible
7326 when a PYTHONSTARTUP file is used.

7340 sq_ass_slice instead of the sq_slice slot.
7341
Georg Brandl3ee81df2008-05-17 18:14:43 +00007342- When printing an unraisable error, don't print exceptions. before

7353 created a weakref on itself during a __del__ call for new-style
7354 classes (classic classes still have the bug).

Georg Brandl2c1375c2006-10-12 11:27:59 +00007394- Bug #1545497: when given an explicit base, int() did ignore NULs
7395 embedded in the string to convert.
7396
Georg Brandl846f73a2006-10-08 07:11:54 +00007397- Bug #1569998: break inside a try statement (outside a loop) is now

Georg Brandl4e933132006-09-06 20:05:58 +00007427- Bug #1542051: Exceptions now correctly call PyObject_GC_UnTrack.

Georg Brandl3ee81df2008-05-17 18:14:43 +00007445 generator expressions (x for x, in ... ) works again. Fixing this
7446 problem required changing the .pyc magic number. This means that
7447 .pyc files generated before 2.5c2 will be regenerated.

Georg Brandl3ee81df2008-05-17 18:14:43 +00008250- The implementation of UnicodeError objects has been simplified
8251 (start and end attributes are now stored directly as Py_ssize_t
8252 members).

Georg Brandl3ee81df2008-05-17 18:14:43 +00008254- Issue #829951: In the smtplib module, SMTP.starttls() now complies
8255 with RFC 3207 and forgets any knowledge obtained from the server not
8256 obtained from the TLS negotiation itself. Patch contributed by Bill
8257 Fenner.
Gregory P. Smith2b3ba582008-01-17 08:03:17 +00008258
Georg Brandl3ee81df2008-05-17 18:14:43 +00008259- Issue #1339: The smtplib.SMTP class has been refactored a bit such
Gregory P. Smithbde4ae42008-01-17 08:35:49 +00008260 that the SMTP.starttls() caller no longer needs to call ehlo()
8261 beforehand. SMTP.starttls() now raises an exception of the server
Georg Brandl3ee81df2008-05-17 18:14:43 +00008262 does not claim to support starttls. Adds the
8263 SMTP.ehlo_or_helo_if_needed() method. Patch contributed by Bill
8264 Fenner.

Georg Brandl3ee81df2008-05-17 18:14:43 +00008306- Patch #976880: ``mmap`` objects now have an ``rfind`` method that
Andrew M. Kuchling5c60bfc2008-01-19 18:18:41 +00008307 works as expected. ``mmap.find`` also takes an optional ``end``
8308 parameter.

8333 contents before adding elements from the iterable. This fix brings
8334 the behavior into line with that for list.__init__().
Raymond Hettingeradf9ffd2007-12-13 00:08:37 +00008335
Georg Brandl3ee81df2008-05-17 18:14:43 +00008336- Added wide char functions to msvcrt module: getwch, getwche, putwch

Georg Brandl3ee81df2008-05-17 18:14:43 +00008343- Marshal.dumps() now expects exact type matches for int, long, float,
8344 complex, tuple, list, dict, set, and frozenset. Formerly, it would
8345 silently miscode subclasses of those types. Now, it raises a
8346 ValueError instead.
Raymond Hettinger12e94202007-11-07 01:13:09 +00008347

Georg Brandl3ee81df2008-05-17 18:14:43 +00008362 time so that opening a database previously created with the DB_DUP
8363 or DB_DUPSORT flag set will keep the proper behavior on subsequent
8364 opens. Specifically: dictionary assignment to a DB object will
8365 replace all values for a given key when the database allows
8366 duplicate values. DB users should use DB.put(k, v) when they want
8367 to store duplicates; not DB[k] = v.
Gregory P. Smithec10a4a2007-11-05 02:32:26 +00008368

8374 characters with ASCII value less than 32. Also, it correctly quotes
8375 dots only if they occur on a single line, as opposed to the previous
8376 behavior of quoting dots if they are the second character of any
8377 line.
Georg Brandl4aef7272007-03-13 22:49:43 +00008378

Georg Brandl3ee81df2008-05-17 18:14:43 +00008783- Removed the macfs module. It had been deprecated since Python 2.5.
8784 This lead to the deprecation of macostools.touched() as it relied
8785 solely on macfs and was a no-op under OS X.
