1684 32-bit-only installer Pythons on systems with Xcode 4 (currently
1685 OS X 10.8, 10.7, and optionally 10.6).
1686 * Backport 3.3.0 fixes to 2.7 branch (for release in 2.7.4)
1687 * Since Xcode 4 removes ppc support, extension module builds now
1688 check for ppc compiler support and by default remove ppc and
1689 ppc64 archs when they are not available.
1690 * Extension module builds now revert to using system installed
1691 headers and libs (/usr and /System/Library) if the SDK used
1692 to build the interpreter is not installed or has moved.
1693 * Try to avoid building extension modules with deprecated
1694 and problematic Apple llvm-gcc compiler. If original compiler
1695 is not available, use clang instead by default.

2045
Mark Dickinsondbbed042011-09-19 16:38:08 +01002046- Issue #12973: Fix overflow checks that invoked undefined behaviour in
2047 int.__pow__. These overflow checks were causing int.__pow__ to produce
2048 incorrect results with recent versions of Clang, as a result of the
Mark Dickinsona96b0d12011-09-24 09:01:16 +01002049 compiler optimizing the check away. Also fix similar overflow checks
2050 in list_repeat (listobject.c) and islice_next (itertoolsmodule.c). These
2051 bugs caused test failures with recent versions of Clang.

2063 cleared by the garbage collector. This fixes a segfault when an instance
2064 and its type get caught in a reference cycle, and the instance's
2065 deallocator calls one of the methods on the type (e.g. when subclassing

Florent Xiclunac2279652012-02-12 14:49:03 +01002119- Issue #13994: Earlier partial revert of Distutils enhancements in 2.7
Ned Deilyc47a4592012-02-11 20:40:24 +01002120 has left two versions of customize_compiler, the original in
2121 distutils.sysconfig and another copy in distutils.ccompiler, with some
2122 parts of distutils calling one and others using the other.

2124 is the case in 3.x.
2125
Ned Deily0d0ea482012-02-10 12:59:06 +01002126- Issue #13590: On OS X 10.7 and 10.6 with Xcode 4.2, building
2127 Distutils-based packages with C extension modules may fail because
2128 Apple has removed gcc-4.2, the version used to build python.org
2129 64-bit/32-bit Pythons. If the user does not explicitly override
2130 the default C compiler by setting the CC environment variable,
2131 Distutils will now attempt to compile extension modules with clang
2132 if gcc-4.2 is required but not found. Also as a convenience, if
2133 the user does explicitly set CC, substitute its value as the default
2134 compiler in the Distutils LDSHARED configuration variable for OS X.
2135 (Note, the python.org 32-bit-only Pythons use gcc-4.0 and the 10.4u
2136 SDK, neither of which are available in Xcode 4. This change does not
2137 attempt to override settings to support their use with Xcode 4.)

Ned Deily87e82bb2011-06-28 19:52:59 -07002387- Issue #9516: On Mac OS X, change Distutils to no longer globally attempt to
2388 check or set the MACOSX_DEPLOYMENT_TARGET environment variable for the
2389 interpreter process. This could cause failures in non-Distutils subprocesses
2390 and was unreliable since tests or user programs could modify the interpreter
Ezio Melotti302ad8d2013-01-19 19:44:58 +02002391 environment after Distutils set it. Instead, have Distutils set the
Ned Deily87e82bb2011-06-28 19:52:59 -07002392 deployment target only in the environment of each build subprocess. It is
2393 still possible to globally override the default by setting
2394 MACOSX_DEPLOYMENT_TARGET before launching the interpreter; its value must be
2395 greater or equal to the default value, the value with which the interpreter
2396 was built.

2425 updating the check interval, so if the user decreases the check interval,
2426 the ticker doesn't have to wind down to zero from the old starting point
2427 before the new interval takes effect. And if the user increases the
2428 interval, it makes sure the new limit takes effect right away rather have an
2429 early task switch before recognizing the new interval.

Raymond Hettinger20397532010-09-12 02:11:45 +00003409- Issue #9825: removed __del__ from the definition of collections.OrderedDict.
3410 This prevents user-created self-referencing ordered dictionaries from
3411 becoming permanently uncollectable GC garbage. The downside is that
3412 removing __del__ means that the internal doubly-linked list has to wait for
3413 GC collection rather than freeing memory immediately when the refcnt drops
3414 to zero.

3422 to fetch the original errno, or to filter timeout errors. Now the
3423 original error is re-raised.

3871
Ezio Melottiab2eb0e2010-06-05 19:21:32 +00003872- Issue #8271: during the decoding of an invalid UTF-8 byte sequence, only the
3873 start byte and the continuation byte(s) are now considered invalid, instead
3874 of the number of bytes specified by the start byte.
3875 E.g.: '\xf1\x80AB'.decode('utf-8', 'replace') now returns u'\ufffdAB' and
3876 replaces with U+FFFD only the start byte ('\xf1') and the continuation byte
3877 ('\x80') even if '\xf1' is the start byte of a 4-bytes sequence.
3878 Previous versions returned a single u'\ufffd'.

3884 gets ignored.

Mark Dickinson4ca7c3c2010-05-30 13:18:10 +00003886- Issue #8748: Fix two issues with comparisons between complex and integer
3887 objects. (1) The comparison could incorrectly return True in some cases
3888 (2**53+1 == complex(2**53) == 2**53), breaking transivity of equality.
3889 (2) The comparison raised an OverflowError for large integers, leading
3890 to unpredictable exceptions when combining integers and complex objects
3891 in sets or dicts.
3892
Mark Dickinson81336372010-05-30 12:12:25 +00003893- Issue #5211: Implicit coercion for the complex type is now completely

Georg Brandlba83f822010-03-14 09:50:54 +00004771 file position when calling `truncate()`. It would previously change the file
4772 position to the given argument, which goes against the tradition of

4776 class used to represent files stored inside an archive. The new
4777 implementation is significantly faster and can be wrapped in a

4779 where interleaved calls to ``read()`` and ``readline()`` give wrong results.

Georg Brandlba83f822010-03-14 09:50:54 +00004870- The ``__complex__()`` method is now looked up on the class of instances to
4871 make it consistent with other special methods.

4875
Mark Dickinson1b34d252010-01-01 17:27:30 +00004876- Issue #5080: A number of functions and methods previously produced a
Georg Brandlba83f822010-03-14 09:50:54 +00004877 DeprecationWarning when passed a float argument where an integer was expected.
4878 These functions and methods now raise TypeError instead. The majority of the
4879 effects of this change are in the extension modules, but some core functions
4880 and methods are affected: notably the 'chr', 'range' and 'xrange' builtins,
4881 and many unicode/str methods.

4897 internal representation of a long.

4993 ``PyArg_ParseTupleAndKeywords()``, ``PyArg_VaParse()``,
4994 ``PyArg_VaParseTupleAndKeywords()`` and ``PyArg_Parse()`` no longer accept
4995 float arguments for integer format codes (other than 'L'): previously an
4996 attempt to pass a float resulted in a DeprecationWarning; now it gives a
4997 TypeError. For the 'L' format code (which previously had no warning) there is
4998 now a DeprecationWarning.

5047 to 'g' for large values.
Amaury Forgeot d'Arcd7288712009-12-01 21:51:04 +00005048
Georg Brandlba83f822010-03-14 09:50:54 +00005049- Remove switch from "%f" formatting to "%g" formatting for floats larger than
5050 1e50 in absolute value.
Mark Dickinson9dd5e162009-11-23 20:54:09 +00005051
Georg Brandlba83f822010-03-14 09:50:54 +00005052- Remove restrictions on precision when formatting floats. E.g., "%.120g" %
5053 1e-100 used to raise OverflowError, but now gives the requested 120
5054 significant digits instead.

Ronald Oussoren315cd0c2009-11-19 16:25:21 +00005062
Georg Brandlba83f822010-03-14 09:50:54 +00005063- Issue #7117: ``repr(x)`` for a float x returns a result based on the shortest
5064 decimal string that's guaranteed to round back to x under correct rounding
5065 (with round-half-to-even rounding mode). Previously it gave a string based on
5066 rounding x to 17 decimal digits. repr(x) for a complex number behaves
5067 similarly. On platforms where the correctly-rounded strtod and dtoa code is
5068 not supported (see below), repr is unchanged.
Mark Dickinsonb678de82009-11-19 18:41:49 +00005069
Georg Brandlba83f822010-03-14 09:50:54 +00005070- Issue #7117: On almost all platforms: float-to-string and string-to-float
5071 conversions within Python are now correctly rounded. Places these conversions
5072 occur include: str for floats and complex numbers; the float and complex
5073 constructors; old-style and new-style numeric formatting; serialization and
5074 deserialization of floats and complex numbers using marshal, pickle and json;
5075 parsing of float and imaginary literals in Python code; Decimal-to-float
5076 conversion.
Mark Dickinsonb678de82009-11-19 18:41:49 +00005077
Georg Brandlba83f822010-03-14 09:50:54 +00005078 The conversions use a Python-adapted version of David Gay's well-known dtoa.c,
5079 providing correctly-rounded strtod and dtoa C functions. This code is
5080 supported on Windows, and on Unix-like platforms using gcc, icc or suncc as
5081 the C compiler. There may be a small number of platforms on which correct
5082 operation of this code cannot be guaranteed, so the code is not used: notably,
5083 this applies to platforms where the C double format is not IEEE 754 binary64,
5084 and to platforms on x86 hardware where the x87 FPU is set to 64-bit precision
5085 and Python's configure script is unable to determine how to change the FPU
5086 precision. On these platforms conversions use the platform strtod and dtoa,
5087 as before.
Mark Dickinsonb678de82009-11-19 18:41:49 +00005088
Georg Brandlba83f822010-03-14 09:50:54 +00005089- Issue #7117: Backport round implementation from Python 3.x. ``round()`` now
5090 uses the correctly-rounded string <-> float conversions described above (when
5091 available), and so produces correctly rounded results that will display nicely
5092 under the float repr. There are two related small changes: (1) round now
5093 accepts any class with an ``__index__()`` method for its second argument (but
5094 no longer accepts floats for the second argument), and (2) an excessively
5095 large second integer argument (e.g., ``round(1.234, 10**100)``) no longer
5096 raises an exception.

Georg Brandlba83f822010-03-14 09:50:54 +00005226- Issue #5829: complex("1e500") no longer raises OverflowError. This makes it
5227 consistent with float("1e500") and interpretation of real and imaginary
5228 literals.

Mark Dickinsonb1d45852009-05-11 15:33:08 +00005237- Issue #5981: Fix three minor inf/nan issues in float.fromhex:
Mark Dickinsonb1d45852009-05-11 15:33:08 +00005238
Georg Brandlba83f822010-03-14 09:50:54 +00005239 (1) inf and nan strings with trailing whitespace were incorrectly rejected;
5240 (2) parsing of strings representing infinities and nans was locale aware; and
5241 (3) the interpretation of fromhex('-nan') didn't match that of float('-nan').

Georg Brandlba83f822010-03-14 09:50:54 +00005243- Issue #5920: For ``float.__format__()``, change the behavior with the empty
5244 presentation type (that is, not one of 'e', 'f', 'g', or 'n') to be like 'g'
5245 but with at least one decimal point and with a default precision
5246 of 12. Previously, the behavior the same but with a default precision of 6.
5247 This more closely matches ``str()``, and reduces surprises when adding
5248 alignment flags to the empty presentation type. This also affects the new
5249 complex.__format__ in the same way.
5250
5251- Issue #5890: In subclasses of 'property' the __doc__ attribute was shadowed by
5252 classtype's, even if it was None. property now inserts the __doc__ into the
5253 subclass instance __dict__.

Antoine Pitrouf8387af2009-03-23 18:41:45 +00005313- Issue #4688: Add a heuristic so that tuples and dicts containing only
Georg Brandlba83f822010-03-14 09:50:54 +00005314 untrackable objects are not tracked by the garbage collector. This can reduce
5315 the size of collections and therefore the garbage collection overhead on

5323 internal representation of integers, for performance reasons. Base 2**30 is
5324 enabled by default on 64-bit machines. Add --enable-big-digits option to
5325 configure, which overrides the default. Add sys.long_info structseq to
5326 provide information about the internal format.

Georg Brandlba83f822010-03-14 09:50:54 +00005473- On windows, ``os.chdir()`` given unicode was not working if

5475 this code path is really executed because I cannot move to such directory on
5476 win2k)

Georg Brandlba83f822010-03-14 09:50:54 +00005478- Issue #4069: When ``set.remove(element)`` is used with a set element, the
5479 element is temporarily replaced with an equivalent frozenset. But the
5480 eventual KeyError would always report the empty ``frozenset()`` as the missing
5481 key. Now it correctly refers to the initial element.

Walter Dörwalded960ac2009-05-03 22:36:33 +00005501- Issue #5108: Handle %s like %S and %R in PyUnicode_FromFormatV(): Call
5502 PyUnicode_DecodeUTF8() once, remember the result and output it in a second
5503 step. This avoids problems with counting UTF-8 bytes that ignores the effect
5504 of using the replace error handler in PyUnicode_DecodeUTF8().
5505
Walter Dörwald726ba8e2009-05-06 14:32:35 +00005506- Issue #3739: The unicode-internal encoder now reports the number of characters

5508
Georg Brandlba83f822010-03-14 09:50:54 +00005509- Issue #2422: When compiled with the ``--with-valgrind`` option, the pymalloc
5510 allocator will be automatically disabled when running under Valgrind. This
5511 gives improved memory leak detection when running under Valgrind, while taking
5512 advantage of pymalloc at other times.

Martin v. Löwis9fa5a282008-09-11 06:53:30 +00006880- Issue #3642: Suppress warning in obmalloc when size_t is larger than uint.
6881
Amaury Forgeot d'Arc05e34492008-09-10 22:04:45 +00006882- Issue #3743: In a few places, PY_FORMAT_SIZE_T was incorrectly used with
6883 PyString_FromFormat or PyErr_Format to display size_t values. The macro
6884 PY_FORMAT_SIZE_T is designed to select the correct format for the OS
6885 ``printf`` function, whereas PyString_FromFormat has an independent
6886 implementation and uses "%zd" on all platforms for size_t values.
6887 This makes a difference on win64, where ``printf`` needs "%Id" to display
6888 64bit values.
6889
Benjamin Peterson97179b02008-09-09 20:55:01 +00006890- Issue #3634: _weakref.ref(Exception).__init__() gave invalid return value on
6891 error.
6892
Amaury Forgeot d'Arcd3ffb892008-09-09 07:24:30 +00006893- Issue #3777: long() applied to a float object now always return a long
6894 object; previously an int would be returned for small values. the __long__
6895 method is allowed to return either an int or a long, but the behaviour of
6896 float objects should not change to respect backward compatibility.
6897
Amaury Forgeot d'Arc3571fbf2008-09-01 19:52:00 +00006898- Issue #3751: str.rpartition would perform a left-partition when called with
6899 a unicode argument.

Vinay Sajip35e3b032008-09-01 14:33:59 +00006904 PyArg_ParseTuple and friends, which occurred when the argument for "s*"
Antoine Pitroud4ae97b2008-08-29 18:39:48 +00006905 was correctly parsed but parsing of subsequent arguments failed.
6906
Vinay Sajip35e3b032008-09-01 14:33:59 +00006907- Issue #2534: speed up isinstance() and issubclass() by 50-70%, so as to
Antoine Pitrou0668c622008-08-26 22:42:08 +00006908 match Python 2.5 speed despite the __instancecheck__ / __subclasscheck__
6909 mechanism. In the process, fix a bug where isinstance() and issubclass(),
6910 when given a tuple of classes as second argument, were looking up
6911 __instancecheck__ / __subclasscheck__ on the tuple rather than on each
6912 type object.
6913
Neal Norwitz18aa3882008-08-24 05:04:52 +00006914- Fix crashes on memory allocation failure found with failmalloc.

Brett Cannon1eaf0742008-09-02 01:25:16 +00006983 warnings.catch_warnings() along with some API cleanup. Expanding the tests
6984 for catch_warnings() also led to an improvement in the raising of a

7057-----------------
7058
Guido van Rossumf8402962008-08-20 15:01:50 +00007059- Issue #1878: Remove Py_TPFLAGS_HAVE_VERSION_TAG from
7060 Py_TPFLAGS_DEFAULT when not building the core. This means 3rd party
7061 extensions do not automatically benefit from the class attribute
7062 cache; they will have to explicitly add Py_TPFLAGS_HAVE_VERSION_TAG
7063 to their tp_flags field if they care. This is a backwards
7064 compatibility feature; in 3.0, all types will use the cache by
7065 default.
7066
Benjamin Petersonf647dc12008-08-20 01:27:30 +00007067- Keyword arguments can now follow starred arguments. (``f(a, *args,
7068 keyword=23)`` is now valid syntax.)
7069
Thomas Heller0ad5ae02008-08-19 19:25:04 +00007070- ctypes function pointers that are COM methods have a boolean True
7071 value again.
7072
Martin v. Löwisf91d46a2008-08-12 14:49:50 +00007073- Issue #3139: Make buffer-interface thread-safe wrt. PyArg_ParseTuple,
7074 by denying s# to parse objects that have a releasebuffer procedure,
7075 and introducing s*.
7076
Georg Brandl1e13ea92008-08-11 09:07:59 +00007077- Issue #3537: Fix an assertion failure when an empty but presized dict
7078 object was stored in the freelist.
7079
Mark Dickinsonb6467572008-08-04 21:30:09 +00007080- Issue #1481296: Make long(float('nan')) and int(float('nan')) raise
7081 ValueError consistently across platforms.
7082
Amaury Forgeot d'Arc39fd6722008-07-31 21:28:03 +00007083- Issue #3479: On platforms where sizeof(int) is smaller than sizeof(long)
7084 (64bit Unix, for example), unichr() would truncate its argument and return
7085 u'\x00' for unichr(2**32). Now it properly raises an OverflowError.
7086
Neal Norwitze7d8be82008-07-31 17:17:14 +00007087- Apply security patches from Apple.
7088
Amaury Forgeot d'Arc246daed2008-07-31 00:42:16 +00007089- Issue #2542: Now that issubclass() may call arbitrary code, ensure that
7090 PyErr_ExceptionMatches returns 0 when an exception occurs there.
7091
Antoine Pitrou92f82162008-07-25 22:22:08 +00007092- Issue #1819: function calls with several named parameters are now on
7093 average 35% faster (as measured by pybench).
7094
Amaury Forgeot d'Arce4921fe2008-07-21 22:00:38 +00007095- Issue #2378: An unexpected UnboundLocalError or NameError could appear when
7096 the python debugger steps into a class statement: the free variables (local
7097 variables defined in an outer scope) would be deleted from the outer scope.
7098
Gregory P. Smith0470bab2008-07-22 04:46:32 +00007099- Issue #2620: Overflow checking when allocating or reallocating memory
7100 was not always being done properly in some python types and extension
7101 modules. PyMem_MALLOC, PyMem_REALLOC, PyMem_NEW and PyMem_RESIZE have
7102 all been updated to perform better checks and places in the code that
7103 would previously leak memory on the error path when such an allocation
7104 failed have been fixed.

7110
Benjamin Petersone977ad42008-08-20 01:42:01 +00007111- The methods ``is_in_tuple()``, ``is_vararg()``, and ``is_keywordarg()`` of
7112 symtable.Symbol have been deprecated for removal in 3.0 and the next release.
7113
Amaury Forgeot d'Arc351ffb82008-08-18 19:23:47 +00007114- Issue #2234: distutils failed for some versions of the cygwin compiler. The
7115 version reported by these tools does not necessarily follow the python

7117
Nick Coghlanf70385a2008-08-18 12:42:46 +00007118- Issue #2235: Added Py3k warnings for types which will become unhashable
7119 under the stricter __hash__ inheritance rules in 3.0. Several types
7120 which did not meet the rules for hash invariants and were already
7121 unhashable in 3.0 have now been explicitly flagged as unhashable in
7122 2.6 as well (collections.Mapping, collections.Set, unittest.TestSuite,
7123 xml.dom.minidom.NamedNodeMap, numbers.Number, UserList.UserList)
7124

7180 the reload() built-in has been removed.
7181
Brett Cannon7e30b672008-08-04 21:52:25 +00007182- Changed code in the following modules/packages to remove warnings raised

Antoine Pitroude781a42008-08-09 12:43:23 +00007194 asking for a specific length. This problem only affected files opened

7237 interaction with the tp_hash slot (added in 2.6b2) are now documented
7238
Nick Coghlan2a0c2b12008-08-04 12:47:17 +00007239- Issue #643841: The language reference now provides more detailed
7240 coverage of the lookup process for special methods. The disclaimers
7241 regarding lack of coverage of new-style classes have also been
7242 removed, since the coverage is now fairly reasonable.

7246================================
7247
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00007248*Release date: 17-Jul-2008*
7249
Raymond Hettingere3ae6552008-06-20 04:18:15 +00007250Core and Builtins
7251-----------------
7252
Georg Brandl3e483f62008-07-16 22:57:41 +00007253- Issue #3156: Fix inconsistent behavior of the bytearray type: all
7254 its methods now allow for items objects that can be converted to
7255 an integer using operator.index().
7256
Mark Dickinson64b7e502008-07-16 09:40:03 +00007257- Issue #3360: Fix incorrect parsing of '020000000000.0', which
7258 produced a ValueError instead of giving the correct float.
7259
Eric Smitha5fa5a22008-07-16 00:11:49 +00007260- Issue #3083: Add alternate (#) formatting for bin, oct, hex output
7261 for str.format(). This adds the prefix 0b, 0o, or 0x, respectively.
7262
Mark Dickinson7103aa42008-07-15 19:08:33 +00007263- Issue #3008: the float type has a new instance method 'float.hex'
7264 and a new class method 'float.fromhex' to convert floating-point
7265 numbers to and from hexadecimal strings, respectively.
7266
Nick Coghlan6d6bd442008-07-15 15:40:22 +00007267- Issue #2235: __hash__ is once again inherited by default. To allow
7268 collections.Hashable to remain meaningful in the presence of the
7269 default hash implementation (object.__hash__), it is now possible
7270 to explicit block inheritance of hash by setting __hash__=None at
7271 the Python level, or tp_hash=PyObject_HashNotImplemented at the C
7272 level.
7273
Nick Coghlanb028f502008-07-13 14:52:36 +00007274- Issue #3221: Issue a RuntimeWarning instead of raising SystemError if
7275 the parent module cannot be found while performing an absolute import.
7276 This means that an incorrectly defined __package__ attribute will
7277 now only prevent relative imports in that module rather than causing
7278 all imports from that module to fail.
7279
Nick Coghlan14ff9942008-07-08 14:21:42 +00007280- Issue #2517: Allow unicode messages in Exceptions again by correctly
7281 bypassing the instance dictionary when looking up __unicode__ on
7282 new-style classes.
7283
Amaury Forgeot d'Arcbdd941f2008-07-01 20:38:04 +00007284- Issue #3242: Fix a crash inside the print statement, if sys.stdout is
7285 set to a custom object whose write() method happens to install
7286 another file in sys.stdout.
7287
Amaury Forgeot d'Arc1f40c8a2008-06-30 22:42:40 +00007288- Issue #3088: Corrected a race condition in classes derived from
7289 threading.local: the first member set by a thread could be saved in
7290 another thread's dictionary.
7291
Mark Dickinson1ec2fcd2008-06-20 14:53:43 +00007292- Issue #3004: Minor change to slice.indices(): the start and stop
7293 arguments are now treated identically, making the behaviour easier
7294 to describe and understand. For example, slice(None, -10,
7295 1).indices(9) now returns (0, 0, 1) instead of (0, -1, 1), and
7296 slice(None, 10, -1).indices(10) returns (9, 9, -1) instead of (9,
7297 10, -1).
7298
Georg Brandl278fc502008-07-19 12:46:12 +00007299- Issue #3219: Calling a function with repeated keyword arguments,
7300 f(a=2, a=23), would not cause a syntax error. This was a regression
7301 from 2.4 caused by the switch to the new compiler.
Benjamin Peterson175e4d92008-07-01 19:34:52 +00007302
Georg Brandl278fc502008-07-19 12:46:12 +00007303- Issue #2862: Make int and float freelist management consistent with
7304 other freelists. Changes their CompactFreeList apis into
7305 ClearFreeList apis and calls them via gc.collect().
Gregory P. Smith2fe77062008-07-06 03:35:58 +00007306

7309
Thomas Heller57adf222008-08-14 19:10:48 +00007310- Issue #3554: ctypes.string_at and ctypes.wstring_at did call Python
7311 api functions without holding the GIL, which could lead to a fatal
7312 error when they failed.
7313
Martin v. Löwisaabf4042008-08-02 07:20:25 +00007314- Issue #799428: Fix Tkinter.Misc._nametowidget to unwrap Tcl command objects.

7323 ForkingPickler.register() to resolve conflict with ctypes.
7324
Vinay Sajip51e65192008-07-18 09:01:10 +00007325- Issue #3090: Fixed ARCHFLAGS parsing on OS/X

7328 a valid dlerror() message.
7329
Thomas Heller2bad6572008-07-15 17:19:50 +00007330- Issue #3258: Fixed a crash when a ctypes POINTER type to an

Amaury Forgeot d'Arc0f7cddc2008-07-06 21:34:39 +00007339- Issue #839496: SimpleHTTPServer used to open text files in text mode. This is
7340 both unnecessary (HTTP allows text content to be sent in several forms) and
Andrew M. Kuchlingcc3f2b12008-07-10 14:43:31 +00007341 wrong because the actual transmitted size could differ from the
Amaury Forgeot d'Arc0f7cddc2008-07-06 21:34:39 +00007342 content-length. The problem had been corrected in the 2.4 branch, but never
7343 merged into trunk.
7344
Georg Brandle78fbcc2008-07-05 10:13:36 +00007345- Issue #2663: add filtering capability to shutil.copytree().

Facundo Batista66c52772008-07-02 16:52:55 +00007357
Nick Coghlanc060b0e2008-07-02 13:09:19 +00007358- Issue #3190: Pydoc now hides the automatic module attribute __package__ (the
7359 handling is now the same as that of other special attributes like __name__).
7360
Brett Cannon8bb8fa52008-07-02 01:57:08 +00007361- Issue #2885 (partial): The urllib.urlopen() function has been deprecated for
7362 removal in Python 3.0 in favor of urllib2.urlopen().

7748 mode or even as a 4-way universal binary (that is, PPC, i386,
Georg Brandl5cc774e2008-06-11 20:28:06 +00007749 PPC64 and x86_64 support in one binary).
Ronald Oussoren5640ce22008-06-05 12:58:24 +00007750
7751 This is controlled by the configure argument ``--with-universal-archs``:
7752
7753 - ``--with-universal-archs=all``: install 4-way universal
7754
7755 - ``--with-universal-archs=32-bit``: install 2-way universal, 32-bit (the default)
7756
7757 - ``--with-universal-archs=64-bit``: install 2-way universal, 64-bit
7758
7759 This option should be used in combination with ``--enable-universalsdk=``.
7760
7761 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 +00007810- Issue #1631171: Re-implement the 'warnings' module in C (the
7811 original Python code has been kept as backup). This will allow for
7812 using the 'warning's machinery in such places as the parser where
7813 use of pure Python code is not possible. Both the ``showarning()``
7814 and ``formatwarning()`` gain an optional 'line' argument which is
7815 not called by default for backwards-compatibility reasons. Setting
7816 ``warnings.showwarning()`` to an implementation that lacks support
7817 for the ``line`` argument will raise a DeprecationWarning.

Georg Brandl3ee81df2008-05-17 18:14:43 +00007880- Issue #2550: The approach used by client/server code for obtaining
7881 ports to listen on in network-oriented tests has been refined in an
7882 effort to facilitate running multiple instances of the entire
7883 regression test suite in parallel without issue.
7884 test_support.bind_port() has been fixed such that it will always
7885 return a unique port -- which wasn't always the case with the
7886 previous implementation, especially if socket options had been set
7887 that affected address reuse (i.e. SO_REUSEADDR, SO_REUSEPORT). The
7888 new implementation of bind_port() will actually raise an exception
7889 if it is passed an AF_INET/SOCK_STREAM socket with either the
7890 SO_REUSEADDR or SO_REUSEPORT socket option set. Furthermore, if
7891 available, bind_port() will set the SO_EXCLUSIVEADDRUSE option on
7892 the socket it's been passed. This currently only applies to
7893 Windows. This option prevents any other sockets from binding to the
7894 host/port we've bound to, thus removing the possibility of the
7895 'non-deterministic' behaviour, as Microsoft puts it, that occurs
7896 when a second SOCK_STREAM socket binds and accepts to a host/port
7897 that's already been bound by another socket. The optional preferred
7898 port parameter to bind_port() has been removed. Under no
7899 circumstances should tests be hard coding ports!
7900
7901 test_support.find_unused_port() has also been introduced, which will
7902 pass a temporary socket object to bind_port() in order to obtain an
7903 unused port. The temporary socket object is then closed and
7904 deleted, and the port is returned. This method should only be used
7905 for obtaining an unused port in order to pass to an external program
7906 (i.e. the -accept [port] argument to openssl's s_server mode) or as
7907 a parameter to a server-oriented class that doesn't give you direct
7908 access to the underlying socket used.
7909
7910 Finally, test_support.HOST has been introduced, which should be used
7911 for the host argument of any relevant socket calls (i.e. bind and
7912 connect).
Trent Nelsone41b0062008-04-08 23:47:30 +00007913
7914 The following tests were updated to following the new conventions:
Georg Brandl3ee81df2008-05-17 18:14:43 +00007915 test_socket, test_smtplib, test_asyncore, test_ssl, test_httplib,
Trent Nelsone41b0062008-04-08 23:47:30 +00007916 test_poplib, test_ftplib, test_telnetlib, test_socketserver,
7917 test_asynchat and test_socket_ssl.
7918
Georg Brandl3ee81df2008-05-17 18:14:43 +00007919 It is now possible for multiple instances of the regression test
7920 suite to run in parallel without issue.

Amaury Forgeot d'Arc9a0d3462008-03-23 09:55:29 +00007974- Issue #1477: With narrow Unicode builds, the unicode escape sequence
Georg Brandl3ee81df2008-05-17 18:14:43 +00007975 \Uxxxxxxxx did not accept values outside the Basic Multilingual
7976 Plane. This affected raw unicode literals and the
7977 'raw-unicode-escape' codec. Now UTF-16 surrogates are generated in
7978 this case, like normal unicode literals and the 'unicode-escape'
7979 codec.

8203 Python 2.6 builtins. The expected usage of the future_builtins
8204 module is:
8205 from future_builtins import hex, oct
8206
Eric Smith7ef40bf2008-02-20 23:34:22 +00008207- Issue #1600: Modifed PyOS_ascii_formatd to use at most 2 digit
8208 exponents for exponents with absolute value < 100. Follows C99
8209 standard. This is a change on Windows, which would use 3 digits.
8210 Also, added 'n' to the formats that PyOS_ascii_formatd understands,
8211 so that any alterations it does to the resulting string will be
8212 available in stringlib/formatter.h (for float.__format__).
8213
Eric Smith5a3c1352008-02-19 13:21:56 +00008214- Implemented PEP 3101, Advanced String Formatting. This adds a new
8215 builtin format(); a format() method for str and unicode; a
8216 __format__() method to object, str, unicode, int, long, float, and
8217 datetime; the class string.Formatter; and the C API
8218 PyObject_Format().
8219
Georg Brandl3ee81df2008-05-17 18:14:43 +00008220- Fixed several potential crashes, all caused by specially crafted
8221 __del__ methods exploiting objects in temporarily inconsistent
8222 state.
Amaury Forgeot d'Arc632fad32008-02-16 20:55:24 +00008223
Vinay Sajipb7edfc42008-04-02 21:10:23 +00008224- Issue #2115: Important speedup in setting __slot__ attributes. Also
Georg Brandl3ee81df2008-05-17 18:14:43 +00008225 prevent a possible crash: an Abstract Base Class would try to access
8226 a slot on a registered virtual subclass.
Amaury Forgeot d'Arc60d6c7f2008-02-15 21:22:45 +00008227

Georg Brandl3ee81df2008-05-17 18:14:43 +00008231- Clear all free lists during a gc.collect() of the highest generation
8232 in order to allow pymalloc to free more arenas. Python may give back
8233 memory to the OS earlier.
Christian Heimes3b718a72008-02-14 12:47:33 +00008234
Georg Brandl3ee81df2008-05-17 18:14:43 +00008235- Issue #2045: Fix an infinite recursion triggered when printing a
8236 subclass of collections.defaultdict, if its default_factory is set
8237 to a bound method.

Georg Brandl3ee81df2008-05-17 18:14:43 +00008265- Patch #1473257: generator objects gain a gi_code attribute. This is
8266 the same object as the func_code attribute of the function that
8267 produced the generator.
Georg Brandl0cdf9a32008-01-26 14:14:20 +00008268
Georg Brandl3ee81df2008-05-17 18:14:43 +00008269- Issue #1920: "while 0" statements were completely removed by the
8270 compiler, even in the presence of an "else" clause, which is
8271 supposed to be run when the condition is false. Now the compiler
8272 correctly emits bytecode for the "else" suite.
Amaury Forgeot d'Arc31eaafe2008-01-24 22:59:25 +00008273
Guido van Rossumeead05f2008-01-24 18:21:02 +00008274- A few crashers fixed: weakref_in_del.py (issue #1377858);

8281
Georg Brandl3ee81df2008-05-17 18:14:43 +00008282- Issue #1915: Python compiles with --enable-unicode=no again. However
Christian Heimes082c9b02008-01-23 14:20:50 +00008283 several extension methods and modules do not work without unicode
8284 support.
8285
Georg Brandl26543b12008-01-21 18:36:51 +00008286- Issue #1882: when compiling code from a string, encoding cookies in the

8290
Georg Brandl6caad7d2008-01-26 14:19:22 +00008291- Issue #1865: ``bytes`` as an alias for ``str`` and b"" as an alias "" were
Christian Heimes288e89a2008-01-18 18:24:07 +00008292 added.
8293
Christian Heimesc94e2b52008-01-14 04:13:37 +00008294- sys.float_info / PyFloat_GetInfo: The floating point information
8295 object was converted from a dict to a specialized structseq object.
8296
Georg Brandl3ee81df2008-05-17 18:14:43 +00008297- Patch #1816: Added sys.flags structseq. It exposes the status of
8298 most command line arguments and PYTHON* environment variables.
Christian Heimesf31b69f2008-01-14 03:42:48 +00008299
Georg Brandl3ee81df2008-05-17 18:14:43 +00008300- Objects/structseq.c: Implemented new structseq representation. The
8301 patch makes structseqs (e.g. the return value of os.stat) more
8302 readable.
Christian Heimes9c201962008-01-14 03:33:52 +00008303
Georg Brandl3ee81df2008-05-17 18:14:43 +00008304- Patch #1700288: added a type attribute cache that caches method
8305 accesses, resulting in speedups in heavily object-oriented code.
Amaury Forgeot d'Arce4c270c2008-01-14 00:29:41 +00008306
Neal Norwitz3fc15b82008-01-10 05:42:58 +00008307- Bug #1776: __import__() no longer accepts filenames on any platform.

8313 envvar and sys.dont_write_bytecode attribute. All these can be set
8314 to forbid Python to attempt to write compiled bytecode files.
Georg Brandl2da0fce2008-01-07 17:09:35 +00008315
Georg Brandl3ee81df2008-05-17 18:14:43 +00008316- Improve some exception messages when Windows fails to load an
8317 extension module. Now we get for example '%1 is not a valid Win32
8318 application' instead of 'error code 193'.

8375
Georg Brandl21e99f42010-03-07 15:23:59 +00008376- The enumerate() built-in function is no longer bounded to sequences
Georg Brandl3ee81df2008-05-17 18:14:43 +00008377 smaller than LONG_MAX. Formerly, it raised an OverflowError. Now,
8378 automatically shifts from ints to longs.
Raymond Hettinger8f669372007-10-03 21:18:11 +00008379
Georg Brandl3ee81df2008-05-17 18:14:43 +00008380- Issue #1686386: Tuple's tp_repr did not take into account the
8381 possibility of having a self-referential tuple, which is possible
8382 from C code. Nor did object's tp_str consider that a type's tp_str
8383 could do something that could lead to an inifinite recursion.
8384 Py_ReprEnter() and Py_EnterRecursiveCall(), respectively, fixed the
8385 issues.
Brett Cannon0b14f242007-09-30 19:45:10 +00008386
Georg Brandl3ee81df2008-05-17 18:14:43 +00008387- Issue #1164: It was possible to trigger deadlock when using the
8388 'print' statement to write to a file since the GIL was not released
8389 as needed. Now PyObject_Print() does the right thing along with
8390 various tp_print implementations of the built-in types and those in
8391 the collections module.

Georg Brandl3ee81df2008-05-17 18:14:43 +00008401 PyObject_Call() never calling back out to Python code to trigger
8402 recursion depth updates/checks. Required the creation of a static

Raymond Hettinger4db5fe92007-04-12 04:10:00 +00008444- Request #1193128: str.translate() now allows a None argument for
8445 translations that only remove characters without re-mapping the
8446 remaining characters.
8447
Georg Brandl5cb76c12007-03-21 09:00:39 +00008448- Patch #1682205: a TypeError while unpacking an iterable is no longer

8452
Guido van Rossum143b5642007-03-23 04:58:42 +00008453- Bug #1683368: The object.__init__() and object.__new__() methods are
8454 now stricter in rejecting excess arguments. The only time when
8455 either allows excess arguments is when it is not overridden and the
8456 other one is. For backwards compatibility, when both are
8457 overridden, it is a deprecation warning (for now; maybe a Py3k
Guido van Rossum234b1ff2007-03-23 19:39:01 +00008458 warning later). Also, type.__init__() insists on the same signature
8459 as supported by type.__new__().

Georg Brandl3ee81df2008-05-17 18:14:43 +00008461- Patch #1675423: PyComplex_AsCComplex() now tries to convert an
8462 object to complex using its __complex__() method before falling back
8463 to the __float__() method. Therefore, the functions in the cmath
8464 module now can operate on objects that define a __complex__()
8465 method.

Georg Brandl7b9c5552007-03-12 14:30:05 +00008483- Bug #1678647: write a newline after printing an exception in any
8484 case, even when converting the value to a string failed.
8485
Georg Brandl871f1bc2007-03-12 13:17:36 +00008486- The dir() function has been extended to call the __dir__() method on
Georg Brandl3ee81df2008-05-17 18:14:43 +00008487 its argument, if it exists. If not, it will work like before. This
8488 allows customizing the output of dir() in the presence of a
8489 __getattr__().

8499 raising a ValueError.
Collin Wintere38051d2007-03-09 20:33:07 +00008500
Georg Brandlaa2321b2007-03-07 00:40:28 +00008501- Patch #703779: unset __file__ in __main__ after running a file. This
Georg Brandl3ee81df2008-05-17 18:14:43 +00008502 makes the filenames the warning module prints much more sensible
8503 when a PYTHONSTARTUP file is used.
Georg Brandlaa2321b2007-03-07 00:40:28 +00008504

8517 sq_ass_slice instead of the sq_slice slot.
8518
Georg Brandl3ee81df2008-05-17 18:14:43 +00008519- When printing an unraisable error, don't print exceptions. before

Georg Brandl2c1375c2006-10-12 11:27:59 +00008571- Bug #1545497: when given an explicit base, int() did ignore NULs
8572 embedded in the string to convert.
8573
Georg Brandl846f73a2006-10-08 07:11:54 +00008574- Bug #1569998: break inside a try statement (outside a loop) is now

Georg Brandl4e933132006-09-06 20:05:58 +00008604- Bug #1542051: Exceptions now correctly call PyObject_GC_UnTrack.

Georg Brandl3ee81df2008-05-17 18:14:43 +00008622 generator expressions (x for x, in ... ) works again. Fixing this
8623 problem required changing the .pyc magic number. This means that

Guido van Rossum8bc09652008-02-21 18:18:37 +00008662- Removed uses of dict.has_key() from distutils, and uses of
8663 callable() from copy_reg.py, so the interpreter now starts up

9418 longer than 3 bytes.
Georg Brandl27562782006-10-27 20:39:43 +00009419
Georg Brandl3ee81df2008-05-17 18:14:43 +00009420- The implementation of UnicodeError objects has been simplified
9421 (start and end attributes are now stored directly as Py_ssize_t
9422 members).

Georg Brandl3ee81df2008-05-17 18:14:43 +00009424- Issue #829951: In the smtplib module, SMTP.starttls() now complies
9425 with RFC 3207 and forgets any knowledge obtained from the server not
9426 obtained from the TLS negotiation itself. Patch contributed by Bill
9427 Fenner.
Gregory P. Smith2b3ba582008-01-17 08:03:17 +00009428
Georg Brandl3ee81df2008-05-17 18:14:43 +00009429- Issue #1339: The smtplib.SMTP class has been refactored a bit such
Gregory P. Smithbde4ae42008-01-17 08:35:49 +00009430 that the SMTP.starttls() caller no longer needs to call ehlo()
9431 beforehand. SMTP.starttls() now raises an exception of the server
Georg Brandl3ee81df2008-05-17 18:14:43 +00009432 does not claim to support starttls. Adds the
9433 SMTP.ehlo_or_helo_if_needed() method. Patch contributed by Bill
9434 Fenner.

Georg Brandl3ee81df2008-05-17 18:14:43 +00009476- Patch #976880: ``mmap`` objects now have an ``rfind`` method that
Andrew M. Kuchling5c60bfc2008-01-19 18:18:41 +00009477 works as expected. ``mmap.find`` also takes an optional ``end``
9478 parameter.

9503 contents before adding elements from the iterable. This fix brings
9504 the behavior into line with that for list.__init__().
Raymond Hettingeradf9ffd2007-12-13 00:08:37 +00009505
Georg Brandl3ee81df2008-05-17 18:14:43 +00009506- Added wide char functions to msvcrt module: getwch, getwche, putwch

9512
Georg Brandl3ee81df2008-05-17 18:14:43 +00009513- Marshal.dumps() now expects exact type matches for int, long, float,
9514 complex, tuple, list, dict, set, and frozenset. Formerly, it would
9515 silently miscode subclasses of those types. Now, it raises a
9516 ValueError instead.
Raymond Hettinger12e94202007-11-07 01:13:09 +00009517

Georg Brandl3ee81df2008-05-17 18:14:43 +00009532 time so that opening a database previously created with the DB_DUP
9533 or DB_DUPSORT flag set will keep the proper behavior on subsequent
9534 opens. Specifically: dictionary assignment to a DB object will
9535 replace all values for a given key when the database allows
9536 duplicate values. DB users should use DB.put(k, v) when they want
9537 to store duplicates; not DB[k] = v.
Gregory P. Smithec10a4a2007-11-05 02:32:26 +00009538

9544 characters with ASCII value less than 32. Also, it correctly quotes
9545 dots only if they occur on a single line, as opposed to the previous
9546 behavior of quoting dots if they are the second character of any
9547 line.
Georg Brandl4aef7272007-03-13 22:49:43 +00009548

Georg Brandl3ee81df2008-05-17 18:14:43 +00009956- Removed the macfs module. It had been deprecated since Python 2.5.
9957 This lead to the deprecation of macostools.touched() as it relied
9958 solely on macfs and was a no-op under OS X.
