Florent Xiclunac2279652012-02-12 14:49:03 +0100948- Issue #13994: Earlier partial revert of Distutils enhancements in 2.7
Ned Deilyc47a4592012-02-11 20:40:24 +0100949 has left two versions of customize_compiler, the original in
950 distutils.sysconfig and another copy in distutils.ccompiler, with some

953 is the case in 3.x.

Ned Deily0d0ea482012-02-10 12:59:06 +0100955- Issue #13590: On OS X 10.7 and 10.6 with Xcode 4.2, building
956 Distutils-based packages with C extension modules may fail because
957 Apple has removed gcc-4.2, the version used to build python.org
958 64-bit/32-bit Pythons. If the user does not explicitly override
959 the default C compiler by setting the CC environment variable,
960 Distutils will now attempt to compile extension modules with clang
961 if gcc-4.2 is required but not found. Also as a convenience, if
962 the user does explicitly set CC, substitute its value as the default
963 compiler in the Distutils LDSHARED configuration variable for OS X.
964 (Note, the python.org 32-bit-only Pythons use gcc-4.0 and the 10.4u
965 SDK, neither of which are available in Xcode 4. This change does not
966 attempt to override settings to support their use with Xcode 4.)

Ned Deily87e82bb2011-06-28 19:52:59 -07001239- Issue #9516: On Mac OS X, change Distutils to no longer globally attempt to
1240 check or set the MACOSX_DEPLOYMENT_TARGET environment variable for the
1241 interpreter process. This could cause failures in non-Distutils subprocesses
1242 and was unreliable since tests or user programs could modify the interpreter
Ezio Melotti302ad8d2013-01-19 19:44:58 +02001243 environment after Distutils set it. Instead, have Distutils set the
Ned Deily87e82bb2011-06-28 19:52:59 -07001244 deployment target only in the environment of each build subprocess. It is
1245 still possible to globally override the default by setting
1246 MACOSX_DEPLOYMENT_TARGET before launching the interpreter; its value must be
1247 greater or equal to the default value, the value with which the interpreter
1248 was built.

1278 the ticker doesn't have to wind down to zero from the old starting point
1279 before the new interval takes effect. And if the user increases the
1280 interval, it makes sure the new limit takes effect right away rather have an
1281 early task switch before recognizing the new interval.

2231
Raymond Hettinger20397532010-09-12 02:11:45 +00002232- Issue #9825: removed __del__ from the definition of collections.OrderedDict.
2233 This prevents user-created self-referencing ordered dictionaries from
2234 becoming permanently uncollectable GC garbage. The downside is that
2235 removing __del__ means that the internal doubly-linked list has to wait for
2236 GC collection rather than freeing memory immediately when the refcnt drops
2237 to zero.
2238

2242
Antoine Pitrouc818ed42010-09-07 21:40:25 +00002243- Issue #9792: In case of connection failure, socket.create_connection()
2244 would swallow the exception and raise a new one, making it impossible
2245 to fetch the original errno, or to filter timeout errors. Now the
2246 original error is re-raised.
2247
Antoine Pitrouf4f61712010-09-07 16:34:47 +00002248- Issue #9758: When fcntl.ioctl() was called with mutable_flag set to True,

2250 be updated back after the system call. Original patch by Brian Brazil.

2267
R. David Murray7c4bf552010-08-25 01:45:57 +00002268- Issue #1194222: email.utils.parsedate now returns RFC2822 compliant four
2269 character years even if the message contains RFC822 two character years.

2284
Antoine Pitrou3ebaed62010-08-21 19:17:25 +00002285- Issue #9617: Signals received during a low-level write operation aren't

2287
Benjamin Peterson52c36052010-08-21 03:03:22 +00002288- Issue #2521: Use weakrefs on for caching in the abc module, so that classes

2290
Raymond Hettingera54b2da2010-08-17 19:03:06 +00002291- Issue #9626: the view methods for collections.OrderedDict() were returning

2301 case in Python 2.5 and earlier).
2302
Antoine Pitroucb4f47c2010-08-11 13:40:17 +00002303- Issue #9550: a BufferedReader could issue an additional read when the

2305 when the underlying raw IO channel was e.g. a socket. Report and original
2306 patch by Jason V. Miller.

2695
Ezio Melottiab2eb0e2010-06-05 19:21:32 +00002696- Issue #8271: during the decoding of an invalid UTF-8 byte sequence, only the
2697 start byte and the continuation byte(s) are now considered invalid, instead
2698 of the number of bytes specified by the start byte.
2699 E.g.: '\xf1\x80AB'.decode('utf-8', 'replace') now returns u'\ufffdAB' and
2700 replaces with U+FFFD only the start byte ('\xf1') and the continuation byte
2701 ('\x80') even if '\xf1' is the start byte of a 4-bytes sequence.
2702 Previous versions returned a single u'\ufffd'.

2706 arises from the "Overriding __eq__ blocks inheritance ..." warning
2707 when turned into an exception: in this case the exception simply
2708 gets ignored.

Mark Dickinson4ca7c3c2010-05-30 13:18:10 +00002710- Issue #8748: Fix two issues with comparisons between complex and integer
2711 objects. (1) The comparison could incorrectly return True in some cases
2712 (2**53+1 == complex(2**53) == 2**53), breaking transivity of equality.
2713 (2) The comparison raised an OverflowError for large integers, leading
2714 to unpredictable exceptions when combining integers and complex objects
2715 in sets or dicts.
2716
Mark Dickinson81336372010-05-30 12:12:25 +00002717- Issue #5211: Implicit coercion for the complex type is now completely
2718 removed. (Coercion for arithmetic operations was already removed in 2.7

Georg Brandlba83f822010-03-14 09:50:54 +00003595 file position when calling `truncate()`. It would previously change the file
3596 position to the given argument, which goes against the tradition of

3600 class used to represent files stored inside an archive. The new
3601 implementation is significantly faster and can be wrapped in a
3602 ``io.BufferedReader`` object for more speedups. It also solves an issue
3603 where interleaved calls to ``read()`` and ``readline()`` give wrong results.

Georg Brandlba83f822010-03-14 09:50:54 +00003694- The ``__complex__()`` method is now looked up on the class of instances to
3695 make it consistent with other special methods.

3699
Mark Dickinson1b34d252010-01-01 17:27:30 +00003700- Issue #5080: A number of functions and methods previously produced a
Georg Brandlba83f822010-03-14 09:50:54 +00003701 DeprecationWarning when passed a float argument where an integer was expected.
3702 These functions and methods now raise TypeError instead. The majority of the
3703 effects of this change are in the extension modules, but some core functions
3704 and methods are affected: notably the 'chr', 'range' and 'xrange' builtins,
3705 and many unicode/str methods.

3721 internal representation of a long.

3729
Georg Brandlba83f822010-03-14 09:50:54 +00003730 These executables now work properly with the arch(1) command: ``arch -ppc

3818 ``PyArg_ParseTupleAndKeywords()``, ``PyArg_VaParse()``,
3819 ``PyArg_VaParseTupleAndKeywords()`` and ``PyArg_Parse()`` no longer accept
3820 float arguments for integer format codes (other than 'L'): previously an
3821 attempt to pass a float resulted in a DeprecationWarning; now it gives a
3822 TypeError. For the 'L' format code (which previously had no warning) there is
3823 now a DeprecationWarning.

3871 upper case. This only affects 'inf' and 'nan', since 'f' no longer converts
3872 to 'g' for large values.
Amaury Forgeot d'Arcd7288712009-12-01 21:51:04 +00003873
Georg Brandlba83f822010-03-14 09:50:54 +00003874- Remove switch from "%f" formatting to "%g" formatting for floats larger than
3875 1e50 in absolute value.

Georg Brandlba83f822010-03-14 09:50:54 +00003877- Remove restrictions on precision when formatting floats. E.g., "%.120g" %
3878 1e-100 used to raise OverflowError, but now gives the requested 120
3879 significant digits instead.

Ronald Oussoren315cd0c2009-11-19 16:25:21 +00003887
Georg Brandlba83f822010-03-14 09:50:54 +00003888- Issue #7117: ``repr(x)`` for a float x returns a result based on the shortest
3889 decimal string that's guaranteed to round back to x under correct rounding
3890 (with round-half-to-even rounding mode). Previously it gave a string based on
3891 rounding x to 17 decimal digits. repr(x) for a complex number behaves
3892 similarly. On platforms where the correctly-rounded strtod and dtoa code is
3893 not supported (see below), repr is unchanged.
Mark Dickinsonb678de82009-11-19 18:41:49 +00003894
Georg Brandlba83f822010-03-14 09:50:54 +00003895- Issue #7117: On almost all platforms: float-to-string and string-to-float
3896 conversions within Python are now correctly rounded. Places these conversions
3897 occur include: str for floats and complex numbers; the float and complex
3898 constructors; old-style and new-style numeric formatting; serialization and
3899 deserialization of floats and complex numbers using marshal, pickle and json;
3900 parsing of float and imaginary literals in Python code; Decimal-to-float
3901 conversion.
Mark Dickinsonb678de82009-11-19 18:41:49 +00003902
Georg Brandlba83f822010-03-14 09:50:54 +00003903 The conversions use a Python-adapted version of David Gay's well-known dtoa.c,
3904 providing correctly-rounded strtod and dtoa C functions. This code is
3905 supported on Windows, and on Unix-like platforms using gcc, icc or suncc as
3906 the C compiler. There may be a small number of platforms on which correct
3907 operation of this code cannot be guaranteed, so the code is not used: notably,
3908 this applies to platforms where the C double format is not IEEE 754 binary64,
3909 and to platforms on x86 hardware where the x87 FPU is set to 64-bit precision
3910 and Python's configure script is unable to determine how to change the FPU
3911 precision. On these platforms conversions use the platform strtod and dtoa,
3912 as before.
Mark Dickinsonb678de82009-11-19 18:41:49 +00003913
Georg Brandlba83f822010-03-14 09:50:54 +00003914- Issue #7117: Backport round implementation from Python 3.x. ``round()`` now
3915 uses the correctly-rounded string <-> float conversions described above (when
3916 available), and so produces correctly rounded results that will display nicely
3917 under the float repr. There are two related small changes: (1) round now
3918 accepts any class with an ``__index__()`` method for its second argument (but
3919 no longer accepts floats for the second argument), and (2) an excessively
3920 large second integer argument (e.g., ``round(1.234, 10**100)``) no longer
3921 raises an exception.

Mark Dickinsonb1d45852009-05-11 15:33:08 +00004063
Georg Brandlba83f822010-03-14 09:50:54 +00004064 (1) inf and nan strings with trailing whitespace were incorrectly rejected;
4065 (2) parsing of strings representing infinities and nans was locale aware; and
4066 (3) the interpretation of fromhex('-nan') didn't match that of float('-nan').

Georg Brandlba83f822010-03-14 09:50:54 +00004068- Issue #5920: For ``float.__format__()``, change the behavior with the empty
4069 presentation type (that is, not one of 'e', 'f', 'g', or 'n') to be like 'g'
4070 but with at least one decimal point and with a default precision
4071 of 12. Previously, the behavior the same but with a default precision of 6.
4072 This more closely matches ``str()``, and reduces surprises when adding
4073 alignment flags to the empty presentation type. This also affects the new
4074 complex.__format__ in the same way.
4075
4076- Issue #5890: In subclasses of 'property' the __doc__ attribute was shadowed by

5504 __long__ method could be packed by 'q', 'Q', '*q', '*Q'; for x with
5505 neither __int__ nor __long__, TypeError used to be raised (with a

5701
Martin v. Löwis9fa5a282008-09-11 06:53:30 +00005702- Issue #3642: Suppress warning in obmalloc when size_t is larger than uint.
5703
Amaury Forgeot d'Arc05e34492008-09-10 22:04:45 +00005704- Issue #3743: In a few places, PY_FORMAT_SIZE_T was incorrectly used with
5705 PyString_FromFormat or PyErr_Format to display size_t values. The macro
5706 PY_FORMAT_SIZE_T is designed to select the correct format for the OS
5707 ``printf`` function, whereas PyString_FromFormat has an independent
5708 implementation and uses "%zd" on all platforms for size_t values.
5709 This makes a difference on win64, where ``printf`` needs "%Id" to display
5710 64bit values.
5711
Benjamin Peterson97179b02008-09-09 20:55:01 +00005712- Issue #3634: _weakref.ref(Exception).__init__() gave invalid return value on
5713 error.
5714
Amaury Forgeot d'Arcd3ffb892008-09-09 07:24:30 +00005715- Issue #3777: long() applied to a float object now always return a long
5716 object; previously an int would be returned for small values. the __long__
5717 method is allowed to return either an int or a long, but the behaviour of
5718 float objects should not change to respect backward compatibility.
5719
Amaury Forgeot d'Arc3571fbf2008-09-01 19:52:00 +00005720- Issue #3751: str.rpartition would perform a left-partition when called with
5721 a unicode argument.

Vinay Sajip35e3b032008-09-01 14:33:59 +00005726 PyArg_ParseTuple and friends, which occurred when the argument for "s*"
Antoine Pitroud4ae97b2008-08-29 18:39:48 +00005727 was correctly parsed but parsing of subsequent arguments failed.
5728
Vinay Sajip35e3b032008-09-01 14:33:59 +00005729- Issue #2534: speed up isinstance() and issubclass() by 50-70%, so as to
Antoine Pitrou0668c622008-08-26 22:42:08 +00005730 match Python 2.5 speed despite the __instancecheck__ / __subclasscheck__
5731 mechanism. In the process, fix a bug where isinstance() and issubclass(),
5732 when given a tuple of classes as second argument, were looking up
5733 __instancecheck__ / __subclasscheck__ on the tuple rather than on each
5734 type object.
5735
Neal Norwitz18aa3882008-08-24 05:04:52 +00005736- Fix crashes on memory allocation failure found with failmalloc.

Brett Cannon1eaf0742008-09-02 01:25:16 +00005805 warnings.catch_warnings() along with some API cleanup. Expanding the tests
5806 for catch_warnings() also led to an improvement in the raising of a

5879-----------------
5880
Guido van Rossumf8402962008-08-20 15:01:50 +00005881- Issue #1878: Remove Py_TPFLAGS_HAVE_VERSION_TAG from
5882 Py_TPFLAGS_DEFAULT when not building the core. This means 3rd party
5883 extensions do not automatically benefit from the class attribute
5884 cache; they will have to explicitly add Py_TPFLAGS_HAVE_VERSION_TAG
5885 to their tp_flags field if they care. This is a backwards
5886 compatibility feature; in 3.0, all types will use the cache by
5887 default.
5888
Benjamin Petersonf647dc12008-08-20 01:27:30 +00005889- Keyword arguments can now follow starred arguments. (``f(a, *args,
5890 keyword=23)`` is now valid syntax.)
5891
Thomas Heller0ad5ae02008-08-19 19:25:04 +00005892- ctypes function pointers that are COM methods have a boolean True
5893 value again.
5894
Martin v. Löwisf91d46a2008-08-12 14:49:50 +00005895- Issue #3139: Make buffer-interface thread-safe wrt. PyArg_ParseTuple,
5896 by denying s# to parse objects that have a releasebuffer procedure,
5897 and introducing s*.
5898
Georg Brandl1e13ea92008-08-11 09:07:59 +00005899- Issue #3537: Fix an assertion failure when an empty but presized dict
5900 object was stored in the freelist.
5901
Mark Dickinsonb6467572008-08-04 21:30:09 +00005902- Issue #1481296: Make long(float('nan')) and int(float('nan')) raise
5903 ValueError consistently across platforms.
5904
Amaury Forgeot d'Arc39fd6722008-07-31 21:28:03 +00005905- Issue #3479: On platforms where sizeof(int) is smaller than sizeof(long)
5906 (64bit Unix, for example), unichr() would truncate its argument and return
5907 u'\x00' for unichr(2**32). Now it properly raises an OverflowError.
5908
Neal Norwitze7d8be82008-07-31 17:17:14 +00005909- Apply security patches from Apple.
5910
Amaury Forgeot d'Arc246daed2008-07-31 00:42:16 +00005911- Issue #2542: Now that issubclass() may call arbitrary code, ensure that
5912 PyErr_ExceptionMatches returns 0 when an exception occurs there.
5913
Antoine Pitrou92f82162008-07-25 22:22:08 +00005914- Issue #1819: function calls with several named parameters are now on
5915 average 35% faster (as measured by pybench).
5916
Amaury Forgeot d'Arce4921fe2008-07-21 22:00:38 +00005917- Issue #2378: An unexpected UnboundLocalError or NameError could appear when
5918 the python debugger steps into a class statement: the free variables (local
5919 variables defined in an outer scope) would be deleted from the outer scope.
5920
Gregory P. Smith0470bab2008-07-22 04:46:32 +00005921- Issue #2620: Overflow checking when allocating or reallocating memory
5922 was not always being done properly in some python types and extension
5923 modules. PyMem_MALLOC, PyMem_REALLOC, PyMem_NEW and PyMem_RESIZE have
5924 all been updated to perform better checks and places in the code that
5925 would previously leak memory on the error path when such an allocation
5926 failed have been fixed.

5932
Benjamin Petersone977ad42008-08-20 01:42:01 +00005933- The methods ``is_in_tuple()``, ``is_vararg()``, and ``is_keywordarg()`` of
5934 symtable.Symbol have been deprecated for removal in 3.0 and the next release.
5935
Amaury Forgeot d'Arc351ffb82008-08-18 19:23:47 +00005936- Issue #2234: distutils failed for some versions of the cygwin compiler. The
5937 version reported by these tools does not necessarily follow the python
5938 version numbering scheme, so the module is less strict when parsing it.
5939
Nick Coghlanf70385a2008-08-18 12:42:46 +00005940- Issue #2235: Added Py3k warnings for types which will become unhashable
5941 under the stricter __hash__ inheritance rules in 3.0. Several types

Antoine Pitroude781a42008-08-09 12:43:23 +00006016 asking for a specific length. This problem only affected files opened

6059 interaction with the tp_hash slot (added in 2.6b2) are now documented
6060
Nick Coghlan2a0c2b12008-08-04 12:47:17 +00006061- Issue #643841: The language reference now provides more detailed

6068================================
6069
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00006070*Release date: 17-Jul-2008*
6071
Raymond Hettingere3ae6552008-06-20 04:18:15 +00006072Core and Builtins
6073-----------------
6074
Georg Brandl3e483f62008-07-16 22:57:41 +00006075- Issue #3156: Fix inconsistent behavior of the bytearray type: all
6076 its methods now allow for items objects that can be converted to
6077 an integer using operator.index().
6078
Mark Dickinson64b7e502008-07-16 09:40:03 +00006079- Issue #3360: Fix incorrect parsing of '020000000000.0', which
6080 produced a ValueError instead of giving the correct float.
6081
Eric Smitha5fa5a22008-07-16 00:11:49 +00006082- Issue #3083: Add alternate (#) formatting for bin, oct, hex output
6083 for str.format(). This adds the prefix 0b, 0o, or 0x, respectively.
6084
Mark Dickinson7103aa42008-07-15 19:08:33 +00006085- Issue #3008: the float type has a new instance method 'float.hex'
6086 and a new class method 'float.fromhex' to convert floating-point
6087 numbers to and from hexadecimal strings, respectively.
6088
Nick Coghlan6d6bd442008-07-15 15:40:22 +00006089- Issue #2235: __hash__ is once again inherited by default. To allow
6090 collections.Hashable to remain meaningful in the presence of the
6091 default hash implementation (object.__hash__), it is now possible
6092 to explicit block inheritance of hash by setting __hash__=None at
6093 the Python level, or tp_hash=PyObject_HashNotImplemented at the C
6094 level.
6095
Nick Coghlanb028f502008-07-13 14:52:36 +00006096- Issue #3221: Issue a RuntimeWarning instead of raising SystemError if
6097 the parent module cannot be found while performing an absolute import.
6098 This means that an incorrectly defined __package__ attribute will
6099 now only prevent relative imports in that module rather than causing
6100 all imports from that module to fail.
6101
Nick Coghlan14ff9942008-07-08 14:21:42 +00006102- Issue #2517: Allow unicode messages in Exceptions again by correctly
6103 bypassing the instance dictionary when looking up __unicode__ on
6104 new-style classes.
6105
Amaury Forgeot d'Arcbdd941f2008-07-01 20:38:04 +00006106- Issue #3242: Fix a crash inside the print statement, if sys.stdout is
6107 set to a custom object whose write() method happens to install
6108 another file in sys.stdout.
6109
Amaury Forgeot d'Arc1f40c8a2008-06-30 22:42:40 +00006110- Issue #3088: Corrected a race condition in classes derived from
6111 threading.local: the first member set by a thread could be saved in
6112 another thread's dictionary.
6113
Mark Dickinson1ec2fcd2008-06-20 14:53:43 +00006114- Issue #3004: Minor change to slice.indices(): the start and stop
6115 arguments are now treated identically, making the behaviour easier
6116 to describe and understand. For example, slice(None, -10,
6117 1).indices(9) now returns (0, 0, 1) instead of (0, -1, 1), and
6118 slice(None, 10, -1).indices(10) returns (9, 9, -1) instead of (9,
6119 10, -1).
6120
Georg Brandl278fc502008-07-19 12:46:12 +00006121- Issue #3219: Calling a function with repeated keyword arguments,
6122 f(a=2, a=23), would not cause a syntax error. This was a regression
6123 from 2.4 caused by the switch to the new compiler.
Benjamin Peterson175e4d92008-07-01 19:34:52 +00006124
Georg Brandl278fc502008-07-19 12:46:12 +00006125- Issue #2862: Make int and float freelist management consistent with
6126 other freelists. Changes their CompactFreeList apis into
6127 ClearFreeList apis and calls them via gc.collect().

6133 api functions without holding the GIL, which could lead to a fatal
6134 error when they failed.
6135
Martin v. Löwisaabf4042008-08-02 07:20:25 +00006136- Issue #799428: Fix Tkinter.Misc._nametowidget to unwrap Tcl command objects.

Amaury Forgeot d'Arc0f7cddc2008-07-06 21:34:39 +00006161- Issue #839496: SimpleHTTPServer used to open text files in text mode. This is
6162 both unnecessary (HTTP allows text content to be sent in several forms) and
Andrew M. Kuchlingcc3f2b12008-07-10 14:43:31 +00006163 wrong because the actual transmitted size could differ from the
Amaury Forgeot d'Arc0f7cddc2008-07-06 21:34:39 +00006164 content-length. The problem had been corrected in the 2.4 branch, but never
6165 merged into trunk.

Nick Coghlanc060b0e2008-07-02 13:09:19 +00006180- Issue #3190: Pydoc now hides the automatic module attribute __package__ (the

6182
Brett Cannon8bb8fa52008-07-02 01:57:08 +00006183- Issue #2885 (partial): The urllib.urlopen() function has been deprecated for

6572 mode or even as a 4-way universal binary (that is, PPC, i386,
Georg Brandl5cc774e2008-06-11 20:28:06 +00006573 PPC64 and x86_64 support in one binary).
Ronald Oussoren5640ce22008-06-05 12:58:24 +00006574
6575 This is controlled by the configure argument ``--with-universal-archs``:
6576
6577 - ``--with-universal-archs=all``: install 4-way universal
6578
6579 - ``--with-universal-archs=32-bit``: install 2-way universal, 32-bit (the default)
6580
6581 - ``--with-universal-archs=64-bit``: install 2-way universal, 64-bit
6582
6583 This option should be used in combination with ``--enable-universalsdk=``.
6584
6585 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 +00006635- Issue #1631171: Re-implement the 'warnings' module in C (the
6636 original Python code has been kept as backup). This will allow for
6637 using the 'warning's machinery in such places as the parser where
6638 use of pure Python code is not possible. Both the ``showarning()``
6639 and ``formatwarning()`` gain an optional 'line' argument which is
6640 not called by default for backwards-compatibility reasons. Setting
6641 ``warnings.showwarning()`` to an implementation that lacks support
6642 for the ``line`` argument will raise a DeprecationWarning.

Georg Brandl3ee81df2008-05-17 18:14:43 +00006705- Issue #2550: The approach used by client/server code for obtaining
6706 ports to listen on in network-oriented tests has been refined in an
6707 effort to facilitate running multiple instances of the entire
6708 regression test suite in parallel without issue.
6709 test_support.bind_port() has been fixed such that it will always
6710 return a unique port -- which wasn't always the case with the
6711 previous implementation, especially if socket options had been set
6712 that affected address reuse (i.e. SO_REUSEADDR, SO_REUSEPORT). The
6713 new implementation of bind_port() will actually raise an exception
6714 if it is passed an AF_INET/SOCK_STREAM socket with either the
6715 SO_REUSEADDR or SO_REUSEPORT socket option set. Furthermore, if
6716 available, bind_port() will set the SO_EXCLUSIVEADDRUSE option on
6717 the socket it's been passed. This currently only applies to
6718 Windows. This option prevents any other sockets from binding to the
6719 host/port we've bound to, thus removing the possibility of the
6720 'non-deterministic' behaviour, as Microsoft puts it, that occurs
6721 when a second SOCK_STREAM socket binds and accepts to a host/port
6722 that's already been bound by another socket. The optional preferred
6723 port parameter to bind_port() has been removed. Under no
6724 circumstances should tests be hard coding ports!
6725
6726 test_support.find_unused_port() has also been introduced, which will
6727 pass a temporary socket object to bind_port() in order to obtain an
6728 unused port. The temporary socket object is then closed and
6729 deleted, and the port is returned. This method should only be used
6730 for obtaining an unused port in order to pass to an external program
6731 (i.e. the -accept [port] argument to openssl's s_server mode) or as
6732 a parameter to a server-oriented class that doesn't give you direct
6733 access to the underlying socket used.
6734
6735 Finally, test_support.HOST has been introduced, which should be used
6736 for the host argument of any relevant socket calls (i.e. bind and
6737 connect).
Trent Nelsone41b0062008-04-08 23:47:30 +00006738
6739 The following tests were updated to following the new conventions:
Georg Brandl3ee81df2008-05-17 18:14:43 +00006740 test_socket, test_smtplib, test_asyncore, test_ssl, test_httplib,
Trent Nelsone41b0062008-04-08 23:47:30 +00006741 test_poplib, test_ftplib, test_telnetlib, test_socketserver,
6742 test_asynchat and test_socket_ssl.
6743
Georg Brandl3ee81df2008-05-17 18:14:43 +00006744 It is now possible for multiple instances of the regression test
6745 suite to run in parallel without issue.

Amaury Forgeot d'Arc9a0d3462008-03-23 09:55:29 +00006799- Issue #1477: With narrow Unicode builds, the unicode escape sequence
Georg Brandl3ee81df2008-05-17 18:14:43 +00006800 \Uxxxxxxxx did not accept values outside the Basic Multilingual
6801 Plane. This affected raw unicode literals and the
6802 'raw-unicode-escape' codec. Now UTF-16 surrogates are generated in
6803 this case, like normal unicode literals and the 'unicode-escape'
6804 codec.

Eric Smitha73fbe72008-02-23 03:09:44 +00007024- Added the future_builtins module, which contains hex() and oct().
7025 These are the PEP 3127 version of these functions, designed to be
7026 compatible with the hex() and oct() builtins from Python 3.0. They
7027 differ slightly in their output formats from the existing, unchanged
7028 Python 2.6 builtins. The expected usage of the future_builtins
7029 module is:

7031
Eric Smith7ef40bf2008-02-20 23:34:22 +00007032- Issue #1600: Modifed PyOS_ascii_formatd to use at most 2 digit
7033 exponents for exponents with absolute value < 100. Follows C99
7034 standard. This is a change on Windows, which would use 3 digits.
7035 Also, added 'n' to the formats that PyOS_ascii_formatd understands,
7036 so that any alterations it does to the resulting string will be
7037 available in stringlib/formatter.h (for float.__format__).
7038
Eric Smith5a3c1352008-02-19 13:21:56 +00007039- Implemented PEP 3101, Advanced String Formatting. This adds a new
7040 builtin format(); a format() method for str and unicode; a
7041 __format__() method to object, str, unicode, int, long, float, and
7042 datetime; the class string.Formatter; and the C API
7043 PyObject_Format().
7044
Georg Brandl3ee81df2008-05-17 18:14:43 +00007045- Fixed several potential crashes, all caused by specially crafted
7046 __del__ methods exploiting objects in temporarily inconsistent
7047 state.
Amaury Forgeot d'Arc632fad32008-02-16 20:55:24 +00007048
Vinay Sajipb7edfc42008-04-02 21:10:23 +00007049- Issue #2115: Important speedup in setting __slot__ attributes. Also
Georg Brandl3ee81df2008-05-17 18:14:43 +00007050 prevent a possible crash: an Abstract Base Class would try to access
7051 a slot on a registered virtual subclass.
Amaury Forgeot d'Arc60d6c7f2008-02-15 21:22:45 +00007052

Georg Brandl3ee81df2008-05-17 18:14:43 +00007056- Clear all free lists during a gc.collect() of the highest generation
7057 in order to allow pymalloc to free more arenas. Python may give back
7058 memory to the OS earlier.
Christian Heimes3b718a72008-02-14 12:47:33 +00007059
Georg Brandl3ee81df2008-05-17 18:14:43 +00007060- Issue #2045: Fix an infinite recursion triggered when printing a
7061 subclass of collections.defaultdict, if its default_factory is set
7062 to a bound method.

Georg Brandl3ee81df2008-05-17 18:14:43 +00007090- Patch #1473257: generator objects gain a gi_code attribute. This is
7091 the same object as the func_code attribute of the function that
7092 produced the generator.
Georg Brandl0cdf9a32008-01-26 14:14:20 +00007093
Georg Brandl3ee81df2008-05-17 18:14:43 +00007094- Issue #1920: "while 0" statements were completely removed by the
7095 compiler, even in the presence of an "else" clause, which is
7096 supposed to be run when the condition is false. Now the compiler
7097 correctly emits bytecode for the "else" suite.
Amaury Forgeot d'Arc31eaafe2008-01-24 22:59:25 +00007098
Guido van Rossumeead05f2008-01-24 18:21:02 +00007099- A few crashers fixed: weakref_in_del.py (issue #1377858);

7106
Georg Brandl3ee81df2008-05-17 18:14:43 +00007107- Issue #1915: Python compiles with --enable-unicode=no again. However
Christian Heimes082c9b02008-01-23 14:20:50 +00007108 several extension methods and modules do not work without unicode
7109 support.
7110
Georg Brandl26543b12008-01-21 18:36:51 +00007111- Issue #1882: when compiling code from a string, encoding cookies in the

7115
Georg Brandl6caad7d2008-01-26 14:19:22 +00007116- Issue #1865: ``bytes`` as an alias for ``str`` and b"" as an alias "" were
Christian Heimes288e89a2008-01-18 18:24:07 +00007117 added.
7118
Christian Heimesc94e2b52008-01-14 04:13:37 +00007119- sys.float_info / PyFloat_GetInfo: The floating point information
7120 object was converted from a dict to a specialized structseq object.
7121
Georg Brandl3ee81df2008-05-17 18:14:43 +00007122- Patch #1816: Added sys.flags structseq. It exposes the status of
7123 most command line arguments and PYTHON* environment variables.
Christian Heimesf31b69f2008-01-14 03:42:48 +00007124
Georg Brandl3ee81df2008-05-17 18:14:43 +00007125- Objects/structseq.c: Implemented new structseq representation. The
7126 patch makes structseqs (e.g. the return value of os.stat) more
7127 readable.
Christian Heimes9c201962008-01-14 03:33:52 +00007128
Georg Brandl3ee81df2008-05-17 18:14:43 +00007129- Patch #1700288: added a type attribute cache that caches method
7130 accesses, resulting in speedups in heavily object-oriented code.
Amaury Forgeot d'Arce4c270c2008-01-14 00:29:41 +00007131
Neal Norwitz3fc15b82008-01-10 05:42:58 +00007132- Bug #1776: __import__() no longer accepts filenames on any platform.

7138 envvar and sys.dont_write_bytecode attribute. All these can be set
7139 to forbid Python to attempt to write compiled bytecode files.
Georg Brandl2da0fce2008-01-07 17:09:35 +00007140
Georg Brandl3ee81df2008-05-17 18:14:43 +00007141- Improve some exception messages when Windows fails to load an
7142 extension module. Now we get for example '%1 is not a valid Win32
7143 application' instead of 'error code 193'.

7200
Georg Brandl21e99f42010-03-07 15:23:59 +00007201- The enumerate() built-in function is no longer bounded to sequences
Georg Brandl3ee81df2008-05-17 18:14:43 +00007202 smaller than LONG_MAX. Formerly, it raised an OverflowError. Now,
7203 automatically shifts from ints to longs.
Raymond Hettinger8f669372007-10-03 21:18:11 +00007204
Georg Brandl3ee81df2008-05-17 18:14:43 +00007205- Issue #1686386: Tuple's tp_repr did not take into account the
7206 possibility of having a self-referential tuple, which is possible
7207 from C code. Nor did object's tp_str consider that a type's tp_str
7208 could do something that could lead to an inifinite recursion.
7209 Py_ReprEnter() and Py_EnterRecursiveCall(), respectively, fixed the
7210 issues.
Brett Cannon0b14f242007-09-30 19:45:10 +00007211
Georg Brandl3ee81df2008-05-17 18:14:43 +00007212- Issue #1164: It was possible to trigger deadlock when using the
7213 'print' statement to write to a file since the GIL was not released
7214 as needed. Now PyObject_Print() does the right thing along with
7215 various tp_print implementations of the built-in types and those in
7216 the collections module.
Brett Cannon01531592007-09-17 03:28:34 +00007217
Georg Brandl3ee81df2008-05-17 18:14:43 +00007218- Issue #1147: Exceptions were directly allowing string exceptions in

Georg Brandl3ee81df2008-05-17 18:14:43 +00007226 PyObject_Call() never calling back out to Python code to trigger
7227 recursion depth updates/checks. Required the creation of a static
7228 RuntimeError instance in case normalizing an exception put the
7229 recursion check value past its limit. Fixes crashers

Georg Brandl5cb76c12007-03-21 09:00:39 +00007273- Patch #1682205: a TypeError while unpacking an iterable is no longer
7274 masked by a generic one with the message "unpack non-sequence".

Guido van Rossum143b5642007-03-23 04:58:42 +00007278- Bug #1683368: The object.__init__() and object.__new__() methods are
7279 now stricter in rejecting excess arguments. The only time when
7280 either allows excess arguments is when it is not overridden and the
7281 other one is. For backwards compatibility, when both are
7282 overridden, it is a deprecation warning (for now; maybe a Py3k
Guido van Rossum234b1ff2007-03-23 19:39:01 +00007283 warning later). Also, type.__init__() insists on the same signature
7284 as supported by type.__new__().

Georg Brandl3ee81df2008-05-17 18:14:43 +00007286- Patch #1675423: PyComplex_AsCComplex() now tries to convert an
7287 object to complex using its __complex__() method before falling back
7288 to the __float__() method. Therefore, the functions in the cmath
7289 module now can operate on objects that define a __complex__()
7290 method.

Georg Brandl7b9c5552007-03-12 14:30:05 +00007308- Bug #1678647: write a newline after printing an exception in any
7309 case, even when converting the value to a string failed.
7310
Georg Brandl871f1bc2007-03-12 13:17:36 +00007311- The dir() function has been extended to call the __dir__() method on
Georg Brandl3ee81df2008-05-17 18:14:43 +00007312 its argument, if it exists. If not, it will work like before. This
7313 allows customizing the output of dir() in the presence of a
7314 __getattr__().

7324 raising a ValueError.

Georg Brandlaa2321b2007-03-07 00:40:28 +00007326- Patch #703779: unset __file__ in __main__ after running a file. This
Georg Brandl3ee81df2008-05-17 18:14:43 +00007327 makes the filenames the warning module prints much more sensible
7328 when a PYTHONSTARTUP file is used.

7342 sq_ass_slice instead of the sq_slice slot.
7343
Georg Brandl3ee81df2008-05-17 18:14:43 +00007344- When printing an unraisable error, don't print exceptions. before

7355 created a weakref on itself during a __del__ call for new-style
7356 classes (classic classes still have the bug).

Georg Brandl2c1375c2006-10-12 11:27:59 +00007396- Bug #1545497: when given an explicit base, int() did ignore NULs
7397 embedded in the string to convert.
7398
Georg Brandl846f73a2006-10-08 07:11:54 +00007399- Bug #1569998: break inside a try statement (outside a loop) is now

Georg Brandl3ee81df2008-05-17 18:14:43 +00007447 generator expressions (x for x, in ... ) works again. Fixing this
7448 problem required changing the .pyc magic number. This means that
7449 .pyc files generated before 2.5c2 will be regenerated.

Georg Brandl3ee81df2008-05-17 18:14:43 +00008252- The implementation of UnicodeError objects has been simplified
8253 (start and end attributes are now stored directly as Py_ssize_t
8254 members).

Georg Brandl3ee81df2008-05-17 18:14:43 +00008256- Issue #829951: In the smtplib module, SMTP.starttls() now complies
8257 with RFC 3207 and forgets any knowledge obtained from the server not
8258 obtained from the TLS negotiation itself. Patch contributed by Bill
8259 Fenner.
Gregory P. Smith2b3ba582008-01-17 08:03:17 +00008260
Georg Brandl3ee81df2008-05-17 18:14:43 +00008261- Issue #1339: The smtplib.SMTP class has been refactored a bit such
Gregory P. Smithbde4ae42008-01-17 08:35:49 +00008262 that the SMTP.starttls() caller no longer needs to call ehlo()
8263 beforehand. SMTP.starttls() now raises an exception of the server
Georg Brandl3ee81df2008-05-17 18:14:43 +00008264 does not claim to support starttls. Adds the
8265 SMTP.ehlo_or_helo_if_needed() method. Patch contributed by Bill
8266 Fenner.

Georg Brandl3ee81df2008-05-17 18:14:43 +00008308- Patch #976880: ``mmap`` objects now have an ``rfind`` method that
Andrew M. Kuchling5c60bfc2008-01-19 18:18:41 +00008309 works as expected. ``mmap.find`` also takes an optional ``end``
8310 parameter.

8335 contents before adding elements from the iterable. This fix brings
8336 the behavior into line with that for list.__init__().
Raymond Hettingeradf9ffd2007-12-13 00:08:37 +00008337
Georg Brandl3ee81df2008-05-17 18:14:43 +00008338- Added wide char functions to msvcrt module: getwch, getwche, putwch

8344
Georg Brandl3ee81df2008-05-17 18:14:43 +00008345- Marshal.dumps() now expects exact type matches for int, long, float,
8346 complex, tuple, list, dict, set, and frozenset. Formerly, it would
8347 silently miscode subclasses of those types. Now, it raises a
8348 ValueError instead.
Raymond Hettinger12e94202007-11-07 01:13:09 +00008349

Georg Brandl3ee81df2008-05-17 18:14:43 +00008364 time so that opening a database previously created with the DB_DUP
8365 or DB_DUPSORT flag set will keep the proper behavior on subsequent
8366 opens. Specifically: dictionary assignment to a DB object will
8367 replace all values for a given key when the database allows
8368 duplicate values. DB users should use DB.put(k, v) when they want
8369 to store duplicates; not DB[k] = v.
Gregory P. Smithec10a4a2007-11-05 02:32:26 +00008370

8376 characters with ASCII value less than 32. Also, it correctly quotes
8377 dots only if they occur on a single line, as opposed to the previous
8378 behavior of quoting dots if they are the second character of any
8379 line.
Georg Brandl4aef7272007-03-13 22:49:43 +00008380

Georg Brandl3ee81df2008-05-17 18:14:43 +00008785- Removed the macfs module. It had been deprecated since Python 2.5.
8786 This lead to the deprecation of macostools.touched() as it relied
8787 solely on macfs and was a no-op under OS X.
