598 the newer 10.5+ 32-bit-only format;
599 and the unchanged 10.6+ 64-/32-bit format.
600 Although binary installers will no longer be available from
601 python.org as of 2.7.8, it will still be possible to build from
602 source on 10.3.9 and 10.4 systems if necessary.

1982 32-bit-only installer Pythons on systems with Xcode 4 (currently
1983 OS X 10.8, 10.7, and optionally 10.6).
1984 * Backport 3.3.0 fixes to 2.7 branch (for release in 2.7.4)
1985 * Since Xcode 4 removes ppc support, extension module builds now
1986 check for ppc compiler support and by default remove ppc and
1987 ppc64 archs when they are not available.
1988 * Extension module builds now revert to using system installed
1989 headers and libs (/usr and /System/Library) if the SDK used
1990 to build the interpreter is not installed or has moved.
1991 * Try to avoid building extension modules with deprecated
1992 and problematic Apple llvm-gcc compiler. If original compiler
1993 is not available, use clang instead by default.

Mark Dickinsondbbed042011-09-19 16:38:08 +01002344- Issue #12973: Fix overflow checks that invoked undefined behaviour in
2345 int.__pow__. These overflow checks were causing int.__pow__ to produce
2346 incorrect results with recent versions of Clang, as a result of the
Mark Dickinsona96b0d12011-09-24 09:01:16 +01002347 compiler optimizing the check away. Also fix similar overflow checks
2348 in list_repeat (listobject.c) and islice_next (itertoolsmodule.c). These
2349 bugs caused test failures with recent versions of Clang.

Florent Xiclunac2279652012-02-12 14:49:03 +01002417- Issue #13994: Earlier partial revert of Distutils enhancements in 2.7
Ned Deilyc47a4592012-02-11 20:40:24 +01002418 has left two versions of customize_compiler, the original in
2419 distutils.sysconfig and another copy in distutils.ccompiler, with some

2422 is the case in 3.x.

Ned Deily0d0ea482012-02-10 12:59:06 +01002424- Issue #13590: On OS X 10.7 and 10.6 with Xcode 4.2, building
2425 Distutils-based packages with C extension modules may fail because
2426 Apple has removed gcc-4.2, the version used to build python.org
2427 64-bit/32-bit Pythons. If the user does not explicitly override
2428 the default C compiler by setting the CC environment variable,
2429 Distutils will now attempt to compile extension modules with clang
2430 if gcc-4.2 is required but not found. Also as a convenience, if
2431 the user does explicitly set CC, substitute its value as the default
2432 compiler in the Distutils LDSHARED configuration variable for OS X.
2433 (Note, the python.org 32-bit-only Pythons use gcc-4.0 and the 10.4u
2434 SDK, neither of which are available in Xcode 4. This change does not
2435 attempt to override settings to support their use with Xcode 4.)

Ned Deily87e82bb2011-06-28 19:52:59 -07002685- Issue #9516: On Mac OS X, change Distutils to no longer globally attempt to
2686 check or set the MACOSX_DEPLOYMENT_TARGET environment variable for the
2687 interpreter process. This could cause failures in non-Distutils subprocesses
2688 and was unreliable since tests or user programs could modify the interpreter
Ezio Melotti302ad8d2013-01-19 19:44:58 +02002689 environment after Distutils set it. Instead, have Distutils set the
Ned Deily87e82bb2011-06-28 19:52:59 -07002690 deployment target only in the environment of each build subprocess. It is
2691 still possible to globally override the default by setting
2692 MACOSX_DEPLOYMENT_TARGET before launching the interpreter; its value must be
2693 greater or equal to the default value, the value with which the interpreter
2694 was built.

2723 updating the check interval, so if the user decreases the check interval,
2724 the ticker doesn't have to wind down to zero from the old starting point
2725 before the new interval takes effect. And if the user increases the
2726 interval, it makes sure the new limit takes effect right away rather have an
2727 early task switch before recognizing the new interval.

3706
Raymond Hettinger20397532010-09-12 02:11:45 +00003707- Issue #9825: removed __del__ from the definition of collections.OrderedDict.
3708 This prevents user-created self-referencing ordered dictionaries from
3709 becoming permanently uncollectable GC garbage. The downside is that
3710 removing __del__ means that the internal doubly-linked list has to wait for
3711 GC collection rather than freeing memory immediately when the refcnt drops
3712 to zero.

3717
Antoine Pitrouc818ed42010-09-07 21:40:25 +00003718- Issue #9792: In case of connection failure, socket.create_connection()

3720 to fetch the original errno, or to filter timeout errors. Now the
3721 original error is re-raised.

4169
Ezio Melottiab2eb0e2010-06-05 19:21:32 +00004170- Issue #8271: during the decoding of an invalid UTF-8 byte sequence, only the
4171 start byte and the continuation byte(s) are now considered invalid, instead
4172 of the number of bytes specified by the start byte.
4173 E.g.: '\xf1\x80AB'.decode('utf-8', 'replace') now returns u'\ufffdAB' and
4174 replaces with U+FFFD only the start byte ('\xf1') and the continuation byte
4175 ('\x80') even if '\xf1' is the start byte of a 4-bytes sequence.
4176 Previous versions returned a single u'\ufffd'.

4180 arises from the "Overriding __eq__ blocks inheritance ..." warning
4181 when turned into an exception: in this case the exception simply
4182 gets ignored.
Mark Dickinson23f0d6b2010-06-05 11:52:24 +00004183
Mark Dickinson4ca7c3c2010-05-30 13:18:10 +00004184- Issue #8748: Fix two issues with comparisons between complex and integer
4185 objects. (1) The comparison could incorrectly return True in some cases
4186 (2**53+1 == complex(2**53) == 2**53), breaking transivity of equality.
4187 (2) The comparison raised an OverflowError for large integers, leading
4188 to unpredictable exceptions when combining integers and complex objects
4189 in sets or dicts.

Mark Dickinson81336372010-05-30 12:12:25 +00004191- Issue #5211: Implicit coercion for the complex type is now completely
4192 removed. (Coercion for arithmetic operations was already removed in 2.7

Victor Stinnerc49dfcc2010-05-25 22:30:32 +00004195- Issue #3798: Write sys.exit() message to sys.stderr to use stderr encoding

Georg Brandlba83f822010-03-14 09:50:54 +00005069 file position when calling `truncate()`. It would previously change the file
5070 position to the given argument, which goes against the tradition of

5074 class used to represent files stored inside an archive. The new
5075 implementation is significantly faster and can be wrapped in a
5076 ``io.BufferedReader`` object for more speedups. It also solves an issue
5077 where interleaved calls to ``read()`` and ``readline()`` give wrong results.

5166-----------------
5167
Georg Brandlba83f822010-03-14 09:50:54 +00005168- The ``__complex__()`` method is now looked up on the class of instances to
5169 make it consistent with other special methods.

5173
Mark Dickinson1b34d252010-01-01 17:27:30 +00005174- Issue #5080: A number of functions and methods previously produced a
Georg Brandlba83f822010-03-14 09:50:54 +00005175 DeprecationWarning when passed a float argument where an integer was expected.
5176 These functions and methods now raise TypeError instead. The majority of the
5177 effects of this change are in the extension modules, but some core functions
5178 and methods are affected: notably the 'chr', 'range' and 'xrange' builtins,
5179 and many unicode/str methods.

5194 least on IEEE 754 platforms), and in particular does not depend on the
5195 internal representation of a long.

5203
Georg Brandlba83f822010-03-14 09:50:54 +00005204 These executables now work properly with the arch(1) command: ``arch -ppc

5291 ``PyArg_ParseTupleAndKeywords()``, ``PyArg_VaParse()``,
5292 ``PyArg_VaParseTupleAndKeywords()`` and ``PyArg_Parse()`` no longer accept
5293 float arguments for integer format codes (other than 'L'): previously an
5294 attempt to pass a float resulted in a DeprecationWarning; now it gives a
5295 TypeError. For the 'L' format code (which previously had no warning) there is
5296 now a DeprecationWarning.

5345 to 'g' for large values.
Amaury Forgeot d'Arcd7288712009-12-01 21:51:04 +00005346
Georg Brandlba83f822010-03-14 09:50:54 +00005347- Remove switch from "%f" formatting to "%g" formatting for floats larger than
5348 1e50 in absolute value.

Ronald Oussoren315cd0c2009-11-19 16:25:21 +00005360
Georg Brandlba83f822010-03-14 09:50:54 +00005361- Issue #7117: ``repr(x)`` for a float x returns a result based on the shortest
5362 decimal string that's guaranteed to round back to x under correct rounding
5363 (with round-half-to-even rounding mode). Previously it gave a string based on
5364 rounding x to 17 decimal digits. repr(x) for a complex number behaves
5365 similarly. On platforms where the correctly-rounded strtod and dtoa code is
5366 not supported (see below), repr is unchanged.
Mark Dickinsonb678de82009-11-19 18:41:49 +00005367
Georg Brandlba83f822010-03-14 09:50:54 +00005368- Issue #7117: On almost all platforms: float-to-string and string-to-float
5369 conversions within Python are now correctly rounded. Places these conversions
5370 occur include: str for floats and complex numbers; the float and complex
5371 constructors; old-style and new-style numeric formatting; serialization and
5372 deserialization of floats and complex numbers using marshal, pickle and json;
5373 parsing of float and imaginary literals in Python code; Decimal-to-float
5374 conversion.
Mark Dickinsonb678de82009-11-19 18:41:49 +00005375
Georg Brandlba83f822010-03-14 09:50:54 +00005376 The conversions use a Python-adapted version of David Gay's well-known dtoa.c,
5377 providing correctly-rounded strtod and dtoa C functions. This code is
5378 supported on Windows, and on Unix-like platforms using gcc, icc or suncc as
5379 the C compiler. There may be a small number of platforms on which correct
5380 operation of this code cannot be guaranteed, so the code is not used: notably,
5381 this applies to platforms where the C double format is not IEEE 754 binary64,
5382 and to platforms on x86 hardware where the x87 FPU is set to 64-bit precision
5383 and Python's configure script is unable to determine how to change the FPU
5384 precision. On these platforms conversions use the platform strtod and dtoa,
5385 as before.
Mark Dickinsonb678de82009-11-19 18:41:49 +00005386
Georg Brandlba83f822010-03-14 09:50:54 +00005387- Issue #7117: Backport round implementation from Python 3.x. ``round()`` now
5388 uses the correctly-rounded string <-> float conversions described above (when
5389 available), and so produces correctly rounded results that will display nicely
5390 under the float repr. There are two related small changes: (1) round now
5391 accepts any class with an ``__index__()`` method for its second argument (but
5392 no longer accepts floats for the second argument), and (2) an excessively
5393 large second integer argument (e.g., ``round(1.234, 10**100)``) no longer
5394 raises an exception.

Georg Brandlba83f822010-03-14 09:50:54 +00005524- Issue #5829: complex("1e500") no longer raises OverflowError. This makes it
5525 consistent with float("1e500") and interpretation of real and imaginary
5526 literals.

Mark Dickinsonb1d45852009-05-11 15:33:08 +00005535- Issue #5981: Fix three minor inf/nan issues in float.fromhex:
Mark Dickinsonb1d45852009-05-11 15:33:08 +00005536
Georg Brandlba83f822010-03-14 09:50:54 +00005537 (1) inf and nan strings with trailing whitespace were incorrectly rejected;
5538 (2) parsing of strings representing infinities and nans was locale aware; and
5539 (3) the interpretation of fromhex('-nan') didn't match that of float('-nan').

Georg Brandlba83f822010-03-14 09:50:54 +00005541- Issue #5920: For ``float.__format__()``, change the behavior with the empty
5542 presentation type (that is, not one of 'e', 'f', 'g', or 'n') to be like 'g'
5543 but with at least one decimal point and with a default precision
5544 of 12. Previously, the behavior the same but with a default precision of 6.
5545 This more closely matches ``str()``, and reduces surprises when adding
5546 alignment flags to the empty presentation type. This also affects the new
5547 complex.__format__ in the same way.
5548
5549- Issue #5890: In subclasses of 'property' the __doc__ attribute was shadowed by
5550 classtype's, even if it was None. property now inserts the __doc__ into the
5551 subclass instance __dict__.

Antoine Pitrouf8387af2009-03-23 18:41:45 +00005611- Issue #4688: Add a heuristic so that tuples and dicts containing only
Georg Brandlba83f822010-03-14 09:50:54 +00005612 untrackable objects are not tracked by the garbage collector. This can reduce
5613 the size of collections and therefore the garbage collection overhead on

5621 internal representation of integers, for performance reasons. Base 2**30 is
5622 enabled by default on 64-bit machines. Add --enable-big-digits option to
5623 configure, which overrides the default. Add sys.long_info structseq to
5624 provide information about the internal format.

5773 this code path is really executed because I cannot move to such directory on

Georg Brandlba83f822010-03-14 09:50:54 +00005776- Issue #4069: When ``set.remove(element)`` is used with a set element, the
5777 element is temporarily replaced with an equivalent frozenset. But the
5778 eventual KeyError would always report the empty ``frozenset()`` as the missing

Walter Dörwalded960ac2009-05-03 22:36:33 +00005799- Issue #5108: Handle %s like %S and %R in PyUnicode_FromFormatV(): Call
5800 PyUnicode_DecodeUTF8() once, remember the result and output it in a second
5801 step. This avoids problems with counting UTF-8 bytes that ignores the effect
5802 of using the replace error handler in PyUnicode_DecodeUTF8().
5803
Walter Dörwald726ba8e2009-05-06 14:32:35 +00005804- Issue #3739: The unicode-internal encoder now reports the number of characters

5806
Georg Brandlba83f822010-03-14 09:50:54 +00005807- Issue #2422: When compiled with the ``--with-valgrind`` option, the pymalloc
5808 allocator will be automatically disabled when running under Valgrind. This
5809 gives improved memory leak detection when running under Valgrind, while taking
5810 advantage of pymalloc at other times.

Martin v. Löwis9fa5a282008-09-11 06:53:30 +00007178- Issue #3642: Suppress warning in obmalloc when size_t is larger than uint.
7179
Amaury Forgeot d'Arc05e34492008-09-10 22:04:45 +00007180- Issue #3743: In a few places, PY_FORMAT_SIZE_T was incorrectly used with
7181 PyString_FromFormat or PyErr_Format to display size_t values. The macro
7182 PY_FORMAT_SIZE_T is designed to select the correct format for the OS
7183 ``printf`` function, whereas PyString_FromFormat has an independent
7184 implementation and uses "%zd" on all platforms for size_t values.
7185 This makes a difference on win64, where ``printf`` needs "%Id" to display
7186 64bit values.
7187
Benjamin Peterson97179b02008-09-09 20:55:01 +00007188- Issue #3634: _weakref.ref(Exception).__init__() gave invalid return value on

Amaury Forgeot d'Arcd3ffb892008-09-09 07:24:30 +00007191- Issue #3777: long() applied to a float object now always return a long
7192 object; previously an int would be returned for small values. the __long__
7193 method is allowed to return either an int or a long, but the behaviour of
7194 float objects should not change to respect backward compatibility.
7195
Amaury Forgeot d'Arc3571fbf2008-09-01 19:52:00 +00007196- Issue #3751: str.rpartition would perform a left-partition when called with

Vinay Sajip35e3b032008-09-01 14:33:59 +00007202 PyArg_ParseTuple and friends, which occurred when the argument for "s*"
Antoine Pitroud4ae97b2008-08-29 18:39:48 +00007203 was correctly parsed but parsing of subsequent arguments failed.
7204
Vinay Sajip35e3b032008-09-01 14:33:59 +00007205- Issue #2534: speed up isinstance() and issubclass() by 50-70%, so as to
Antoine Pitrou0668c622008-08-26 22:42:08 +00007206 match Python 2.5 speed despite the __instancecheck__ / __subclasscheck__
7207 mechanism. In the process, fix a bug where isinstance() and issubclass(),
7208 when given a tuple of classes as second argument, were looking up
7209 __instancecheck__ / __subclasscheck__ on the tuple rather than on each
7210 type object.
7211
Neal Norwitz18aa3882008-08-24 05:04:52 +00007212- Fix crashes on memory allocation failure found with failmalloc.

Brett Cannon1eaf0742008-09-02 01:25:16 +00007281 warnings.catch_warnings() along with some API cleanup. Expanding the tests
7282 for catch_warnings() also led to an improvement in the raising of a

7355-----------------
7356
Guido van Rossumf8402962008-08-20 15:01:50 +00007357- Issue #1878: Remove Py_TPFLAGS_HAVE_VERSION_TAG from
7358 Py_TPFLAGS_DEFAULT when not building the core. This means 3rd party
7359 extensions do not automatically benefit from the class attribute
7360 cache; they will have to explicitly add Py_TPFLAGS_HAVE_VERSION_TAG
7361 to their tp_flags field if they care. This is a backwards
7362 compatibility feature; in 3.0, all types will use the cache by
7363 default.
7364
Benjamin Petersonf647dc12008-08-20 01:27:30 +00007365- Keyword arguments can now follow starred arguments. (``f(a, *args,
7366 keyword=23)`` is now valid syntax.)
7367
Thomas Heller0ad5ae02008-08-19 19:25:04 +00007368- ctypes function pointers that are COM methods have a boolean True
7369 value again.
7370
Martin v. Löwisf91d46a2008-08-12 14:49:50 +00007371- Issue #3139: Make buffer-interface thread-safe wrt. PyArg_ParseTuple,
7372 by denying s# to parse objects that have a releasebuffer procedure,
7373 and introducing s*.
7374
Georg Brandl1e13ea92008-08-11 09:07:59 +00007375- Issue #3537: Fix an assertion failure when an empty but presized dict
7376 object was stored in the freelist.
7377
Mark Dickinsonb6467572008-08-04 21:30:09 +00007378- Issue #1481296: Make long(float('nan')) and int(float('nan')) raise
7379 ValueError consistently across platforms.
7380
Amaury Forgeot d'Arc39fd6722008-07-31 21:28:03 +00007381- Issue #3479: On platforms where sizeof(int) is smaller than sizeof(long)
7382 (64bit Unix, for example), unichr() would truncate its argument and return
7383 u'\x00' for unichr(2**32). Now it properly raises an OverflowError.
7384
Neal Norwitze7d8be82008-07-31 17:17:14 +00007385- Apply security patches from Apple.
7386
Amaury Forgeot d'Arc246daed2008-07-31 00:42:16 +00007387- Issue #2542: Now that issubclass() may call arbitrary code, ensure that
7388 PyErr_ExceptionMatches returns 0 when an exception occurs there.
7389
Antoine Pitrou92f82162008-07-25 22:22:08 +00007390- Issue #1819: function calls with several named parameters are now on
7391 average 35% faster (as measured by pybench).
7392
Amaury Forgeot d'Arce4921fe2008-07-21 22:00:38 +00007393- Issue #2378: An unexpected UnboundLocalError or NameError could appear when
7394 the python debugger steps into a class statement: the free variables (local
7395 variables defined in an outer scope) would be deleted from the outer scope.
7396
Gregory P. Smith0470bab2008-07-22 04:46:32 +00007397- Issue #2620: Overflow checking when allocating or reallocating memory
7398 was not always being done properly in some python types and extension
7399 modules. PyMem_MALLOC, PyMem_REALLOC, PyMem_NEW and PyMem_RESIZE have
7400 all been updated to perform better checks and places in the code that
7401 would previously leak memory on the error path when such an allocation
7402 failed have been fixed.

7408
Benjamin Petersone977ad42008-08-20 01:42:01 +00007409- The methods ``is_in_tuple()``, ``is_vararg()``, and ``is_keywordarg()`` of
7410 symtable.Symbol have been deprecated for removal in 3.0 and the next release.
7411
Amaury Forgeot d'Arc351ffb82008-08-18 19:23:47 +00007412- Issue #2234: distutils failed for some versions of the cygwin compiler. The
7413 version reported by these tools does not necessarily follow the python

7415
Nick Coghlanf70385a2008-08-18 12:42:46 +00007416- Issue #2235: Added Py3k warnings for types which will become unhashable
7417 under the stricter __hash__ inheritance rules in 3.0. Several types
7418 which did not meet the rules for hash invariants and were already
7419 unhashable in 3.0 have now been explicitly flagged as unhashable in
7420 2.6 as well (collections.Mapping, collections.Set, unittest.TestSuite,
7421 xml.dom.minidom.NamedNodeMap, numbers.Number, UserList.UserList)
7422
Brett Cannon88f801d2008-08-18 00:46:22 +00007423- Update __all__ for cookielib, csv, os, urllib2, and weakref to include things

7478 the reload() built-in has been removed.
7479
Brett Cannon7e30b672008-08-04 21:52:25 +00007480- Changed code in the following modules/packages to remove warnings raised

Antoine Pitroude781a42008-08-09 12:43:23 +00007492 asking for a specific length. This problem only affected files opened
7493 using the new "io" module, not the built-in open() function.

7535 interaction with the tp_hash slot (added in 2.6b2) are now documented
7536
Nick Coghlan2a0c2b12008-08-04 12:47:17 +00007537- Issue #643841: The language reference now provides more detailed
7538 coverage of the lookup process for special methods. The disclaimers
7539 regarding lack of coverage of new-style classes have also been
7540 removed, since the coverage is now fairly reasonable.

7544================================
7545
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00007546*Release date: 17-Jul-2008*
7547
Raymond Hettingere3ae6552008-06-20 04:18:15 +00007548Core and Builtins
7549-----------------
7550
Georg Brandl3e483f62008-07-16 22:57:41 +00007551- Issue #3156: Fix inconsistent behavior of the bytearray type: all
7552 its methods now allow for items objects that can be converted to
7553 an integer using operator.index().
7554
Mark Dickinson64b7e502008-07-16 09:40:03 +00007555- Issue #3360: Fix incorrect parsing of '020000000000.0', which
7556 produced a ValueError instead of giving the correct float.
7557
Eric Smitha5fa5a22008-07-16 00:11:49 +00007558- Issue #3083: Add alternate (#) formatting for bin, oct, hex output
7559 for str.format(). This adds the prefix 0b, 0o, or 0x, respectively.
7560
Mark Dickinson7103aa42008-07-15 19:08:33 +00007561- Issue #3008: the float type has a new instance method 'float.hex'
7562 and a new class method 'float.fromhex' to convert floating-point
7563 numbers to and from hexadecimal strings, respectively.
7564
Nick Coghlan6d6bd442008-07-15 15:40:22 +00007565- Issue #2235: __hash__ is once again inherited by default. To allow
7566 collections.Hashable to remain meaningful in the presence of the
7567 default hash implementation (object.__hash__), it is now possible
7568 to explicit block inheritance of hash by setting __hash__=None at
7569 the Python level, or tp_hash=PyObject_HashNotImplemented at the C
7570 level.
7571
Nick Coghlanb028f502008-07-13 14:52:36 +00007572- Issue #3221: Issue a RuntimeWarning instead of raising SystemError if
7573 the parent module cannot be found while performing an absolute import.
7574 This means that an incorrectly defined __package__ attribute will
7575 now only prevent relative imports in that module rather than causing
7576 all imports from that module to fail.
7577
Nick Coghlan14ff9942008-07-08 14:21:42 +00007578- Issue #2517: Allow unicode messages in Exceptions again by correctly
7579 bypassing the instance dictionary when looking up __unicode__ on
7580 new-style classes.
7581
Amaury Forgeot d'Arcbdd941f2008-07-01 20:38:04 +00007582- Issue #3242: Fix a crash inside the print statement, if sys.stdout is
7583 set to a custom object whose write() method happens to install
7584 another file in sys.stdout.
7585
Amaury Forgeot d'Arc1f40c8a2008-06-30 22:42:40 +00007586- Issue #3088: Corrected a race condition in classes derived from
7587 threading.local: the first member set by a thread could be saved in
7588 another thread's dictionary.
7589
Mark Dickinson1ec2fcd2008-06-20 14:53:43 +00007590- Issue #3004: Minor change to slice.indices(): the start and stop
7591 arguments are now treated identically, making the behaviour easier
7592 to describe and understand. For example, slice(None, -10,
7593 1).indices(9) now returns (0, 0, 1) instead of (0, -1, 1), and
7594 slice(None, 10, -1).indices(10) returns (9, 9, -1) instead of (9,
7595 10, -1).
7596
Georg Brandl278fc502008-07-19 12:46:12 +00007597- Issue #3219: Calling a function with repeated keyword arguments,
7598 f(a=2, a=23), would not cause a syntax error. This was a regression
7599 from 2.4 caused by the switch to the new compiler.
Benjamin Peterson175e4d92008-07-01 19:34:52 +00007600
Georg Brandl278fc502008-07-19 12:46:12 +00007601- Issue #2862: Make int and float freelist management consistent with
7602 other freelists. Changes their CompactFreeList apis into
7603 ClearFreeList apis and calls them via gc.collect().

Thomas Heller57adf222008-08-14 19:10:48 +00007608- Issue #3554: ctypes.string_at and ctypes.wstring_at did call Python
7609 api functions without holding the GIL, which could lead to a fatal
7610 error when they failed.
7611
Martin v. Löwisaabf4042008-08-02 07:20:25 +00007612- Issue #799428: Fix Tkinter.Misc._nametowidget to unwrap Tcl command objects.

Amaury Forgeot d'Arc0f7cddc2008-07-06 21:34:39 +00007637- Issue #839496: SimpleHTTPServer used to open text files in text mode. This is
7638 both unnecessary (HTTP allows text content to be sent in several forms) and
Andrew M. Kuchlingcc3f2b12008-07-10 14:43:31 +00007639 wrong because the actual transmitted size could differ from the
Amaury Forgeot d'Arc0f7cddc2008-07-06 21:34:39 +00007640 content-length. The problem had been corrected in the 2.4 branch, but never
7641 merged into trunk.

Nick Coghlanc060b0e2008-07-02 13:09:19 +00007656- Issue #3190: Pydoc now hides the automatic module attribute __package__ (the
7657 handling is now the same as that of other special attributes like __name__).
7658
Brett Cannon8bb8fa52008-07-02 01:57:08 +00007659- Issue #2885 (partial): The urllib.urlopen() function has been deprecated for
7660 removal in Python 3.0 in favor of urllib2.urlopen().

8046 mode or even as a 4-way universal binary (that is, PPC, i386,
Georg Brandl5cc774e2008-06-11 20:28:06 +00008047 PPC64 and x86_64 support in one binary).
Ronald Oussoren5640ce22008-06-05 12:58:24 +00008048
8049 This is controlled by the configure argument ``--with-universal-archs``:
8050
8051 - ``--with-universal-archs=all``: install 4-way universal
8052
8053 - ``--with-universal-archs=32-bit``: install 2-way universal, 32-bit (the default)
8054
8055 - ``--with-universal-archs=64-bit``: install 2-way universal, 64-bit
8056
8057 This option should be used in combination with ``--enable-universalsdk=``.
8058
8059 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 +00008108- Issue #1631171: Re-implement the 'warnings' module in C (the
8109 original Python code has been kept as backup). This will allow for
8110 using the 'warning's machinery in such places as the parser where
8111 use of pure Python code is not possible. Both the ``showarning()``
8112 and ``formatwarning()`` gain an optional 'line' argument which is
8113 not called by default for backwards-compatibility reasons. Setting
8114 ``warnings.showwarning()`` to an implementation that lacks support
8115 for the ``line`` argument will raise a DeprecationWarning.

Georg Brandl3ee81df2008-05-17 18:14:43 +00008178- Issue #2550: The approach used by client/server code for obtaining
8179 ports to listen on in network-oriented tests has been refined in an
8180 effort to facilitate running multiple instances of the entire
8181 regression test suite in parallel without issue.
8182 test_support.bind_port() has been fixed such that it will always
8183 return a unique port -- which wasn't always the case with the
8184 previous implementation, especially if socket options had been set
8185 that affected address reuse (i.e. SO_REUSEADDR, SO_REUSEPORT). The
8186 new implementation of bind_port() will actually raise an exception
8187 if it is passed an AF_INET/SOCK_STREAM socket with either the
8188 SO_REUSEADDR or SO_REUSEPORT socket option set. Furthermore, if
8189 available, bind_port() will set the SO_EXCLUSIVEADDRUSE option on
8190 the socket it's been passed. This currently only applies to
8191 Windows. This option prevents any other sockets from binding to the
8192 host/port we've bound to, thus removing the possibility of the
8193 'non-deterministic' behaviour, as Microsoft puts it, that occurs
8194 when a second SOCK_STREAM socket binds and accepts to a host/port
8195 that's already been bound by another socket. The optional preferred
8196 port parameter to bind_port() has been removed. Under no
8197 circumstances should tests be hard coding ports!
8198
8199 test_support.find_unused_port() has also been introduced, which will
8200 pass a temporary socket object to bind_port() in order to obtain an
8201 unused port. The temporary socket object is then closed and
8202 deleted, and the port is returned. This method should only be used
8203 for obtaining an unused port in order to pass to an external program
8204 (i.e. the -accept [port] argument to openssl's s_server mode) or as
8205 a parameter to a server-oriented class that doesn't give you direct
8206 access to the underlying socket used.
8207
8208 Finally, test_support.HOST has been introduced, which should be used
8209 for the host argument of any relevant socket calls (i.e. bind and
8210 connect).
Trent Nelsone41b0062008-04-08 23:47:30 +00008211
8212 The following tests were updated to following the new conventions:
Georg Brandl3ee81df2008-05-17 18:14:43 +00008213 test_socket, test_smtplib, test_asyncore, test_ssl, test_httplib,
Trent Nelsone41b0062008-04-08 23:47:30 +00008214 test_poplib, test_ftplib, test_telnetlib, test_socketserver,
8215 test_asynchat and test_socket_ssl.
8216
Georg Brandl3ee81df2008-05-17 18:14:43 +00008217 It is now possible for multiple instances of the regression test
8218 suite to run in parallel without issue.

Amaury Forgeot d'Arc9a0d3462008-03-23 09:55:29 +00008272- Issue #1477: With narrow Unicode builds, the unicode escape sequence
Georg Brandl3ee81df2008-05-17 18:14:43 +00008273 \Uxxxxxxxx did not accept values outside the Basic Multilingual
8274 Plane. This affected raw unicode literals and the
8275 'raw-unicode-escape' codec. Now UTF-16 surrogates are generated in
8276 this case, like normal unicode literals and the 'unicode-escape'
8277 codec.

8501 Python 2.6 builtins. The expected usage of the future_builtins
8502 module is:
8503 from future_builtins import hex, oct
8504
Eric Smith7ef40bf2008-02-20 23:34:22 +00008505- Issue #1600: Modifed PyOS_ascii_formatd to use at most 2 digit
8506 exponents for exponents with absolute value < 100. Follows C99
8507 standard. This is a change on Windows, which would use 3 digits.
8508 Also, added 'n' to the formats that PyOS_ascii_formatd understands,
8509 so that any alterations it does to the resulting string will be
8510 available in stringlib/formatter.h (for float.__format__).
8511
Eric Smith5a3c1352008-02-19 13:21:56 +00008512- Implemented PEP 3101, Advanced String Formatting. This adds a new
8513 builtin format(); a format() method for str and unicode; a
8514 __format__() method to object, str, unicode, int, long, float, and
8515 datetime; the class string.Formatter; and the C API
8516 PyObject_Format().
8517
Georg Brandl3ee81df2008-05-17 18:14:43 +00008518- Fixed several potential crashes, all caused by specially crafted
8519 __del__ methods exploiting objects in temporarily inconsistent
8520 state.

Georg Brandl3ee81df2008-05-17 18:14:43 +00008563- Patch #1473257: generator objects gain a gi_code attribute. This is
8564 the same object as the func_code attribute of the function that
8565 produced the generator.
Georg Brandl0cdf9a32008-01-26 14:14:20 +00008566
Georg Brandl3ee81df2008-05-17 18:14:43 +00008567- Issue #1920: "while 0" statements were completely removed by the
8568 compiler, even in the presence of an "else" clause, which is
8569 supposed to be run when the condition is false. Now the compiler
8570 correctly emits bytecode for the "else" suite.
Amaury Forgeot d'Arc31eaafe2008-01-24 22:59:25 +00008571
Guido van Rossumeead05f2008-01-24 18:21:02 +00008572- A few crashers fixed: weakref_in_del.py (issue #1377858);

8579
Georg Brandl3ee81df2008-05-17 18:14:43 +00008580- Issue #1915: Python compiles with --enable-unicode=no again. However
Christian Heimes082c9b02008-01-23 14:20:50 +00008581 several extension methods and modules do not work without unicode
8582 support.
8583

8588
Georg Brandl6caad7d2008-01-26 14:19:22 +00008589- Issue #1865: ``bytes`` as an alias for ``str`` and b"" as an alias "" were
Christian Heimes288e89a2008-01-18 18:24:07 +00008590 added.
8591
Christian Heimesc94e2b52008-01-14 04:13:37 +00008592- sys.float_info / PyFloat_GetInfo: The floating point information
8593 object was converted from a dict to a specialized structseq object.
8594
Georg Brandl3ee81df2008-05-17 18:14:43 +00008595- Patch #1816: Added sys.flags structseq. It exposes the status of
8596 most command line arguments and PYTHON* environment variables.
Christian Heimesf31b69f2008-01-14 03:42:48 +00008597
Georg Brandl3ee81df2008-05-17 18:14:43 +00008598- Objects/structseq.c: Implemented new structseq representation. The
8599 patch makes structseqs (e.g. the return value of os.stat) more
8600 readable.
Christian Heimes9c201962008-01-14 03:33:52 +00008601
Georg Brandl3ee81df2008-05-17 18:14:43 +00008602- Patch #1700288: added a type attribute cache that caches method
8603 accesses, resulting in speedups in heavily object-oriented code.
Amaury Forgeot d'Arce4c270c2008-01-14 00:29:41 +00008604

Georg Brandl3ee81df2008-05-17 18:14:43 +00008675 smaller than LONG_MAX. Formerly, it raised an OverflowError. Now,
8676 automatically shifts from ints to longs.
Raymond Hettinger8f669372007-10-03 21:18:11 +00008677
Georg Brandl3ee81df2008-05-17 18:14:43 +00008678- Issue #1686386: Tuple's tp_repr did not take into account the
8679 possibility of having a self-referential tuple, which is possible
8680 from C code. Nor did object's tp_str consider that a type's tp_str
8681 could do something that could lead to an inifinite recursion.
8682 Py_ReprEnter() and Py_EnterRecursiveCall(), respectively, fixed the
8683 issues.
Brett Cannon0b14f242007-09-30 19:45:10 +00008684

8686 'print' statement to write to a file since the GIL was not released
8687 as needed. Now PyObject_Print() does the right thing along with
8688 various tp_print implementations of the built-in types and those in
8689 the collections module.

Georg Brandl3ee81df2008-05-17 18:14:43 +00008699 PyObject_Call() never calling back out to Python code to trigger
8700 recursion depth updates/checks. Required the creation of a static

Raymond Hettinger4db5fe92007-04-12 04:10:00 +00008742- Request #1193128: str.translate() now allows a None argument for
8743 translations that only remove characters without re-mapping the
8744 remaining characters.
8745
Georg Brandl5cb76c12007-03-21 09:00:39 +00008746- Patch #1682205: a TypeError while unpacking an iterable is no longer

8750
Guido van Rossum143b5642007-03-23 04:58:42 +00008751- Bug #1683368: The object.__init__() and object.__new__() methods are
8752 now stricter in rejecting excess arguments. The only time when
8753 either allows excess arguments is when it is not overridden and the
8754 other one is. For backwards compatibility, when both are
8755 overridden, it is a deprecation warning (for now; maybe a Py3k
Guido van Rossum234b1ff2007-03-23 19:39:01 +00008756 warning later). Also, type.__init__() insists on the same signature
8757 as supported by type.__new__().

Georg Brandl3ee81df2008-05-17 18:14:43 +00008759- Patch #1675423: PyComplex_AsCComplex() now tries to convert an
8760 object to complex using its __complex__() method before falling back
8761 to the __float__() method. Therefore, the functions in the cmath
8762 module now can operate on objects that define a __complex__()
8763 method.

Georg Brandl7b9c5552007-03-12 14:30:05 +00008781- Bug #1678647: write a newline after printing an exception in any
8782 case, even when converting the value to a string failed.
8783
Georg Brandl871f1bc2007-03-12 13:17:36 +00008784- The dir() function has been extended to call the __dir__() method on
Georg Brandl3ee81df2008-05-17 18:14:43 +00008785 its argument, if it exists. If not, it will work like before. This
8786 allows customizing the output of dir() in the presence of a
8787 __getattr__().

8797 raising a ValueError.
Collin Wintere38051d2007-03-09 20:33:07 +00008798
Georg Brandlaa2321b2007-03-07 00:40:28 +00008799- Patch #703779: unset __file__ in __main__ after running a file. This
Georg Brandl3ee81df2008-05-17 18:14:43 +00008800 makes the filenames the warning module prints much more sensible
8801 when a PYTHONSTARTUP file is used.

8815 sq_ass_slice instead of the sq_slice slot.
8816
Georg Brandl3ee81df2008-05-17 18:14:43 +00008817- When printing an unraisable error, don't print exceptions. before

Georg Brandl2c1375c2006-10-12 11:27:59 +00008869- Bug #1545497: when given an explicit base, int() did ignore NULs
8870 embedded in the string to convert.
8871
Georg Brandl846f73a2006-10-08 07:11:54 +00008872- Bug #1569998: break inside a try statement (outside a loop) is now

Georg Brandl4e933132006-09-06 20:05:58 +00008902- Bug #1542051: Exceptions now correctly call PyObject_GC_UnTrack.

Georg Brandl3ee81df2008-05-17 18:14:43 +00008920 generator expressions (x for x, in ... ) works again. Fixing this

Georg Brandl3ee81df2008-05-17 18:14:43 +00009718- The implementation of UnicodeError objects has been simplified
9719 (start and end attributes are now stored directly as Py_ssize_t
9720 members).

Georg Brandl3ee81df2008-05-17 18:14:43 +00009722- Issue #829951: In the smtplib module, SMTP.starttls() now complies
9723 with RFC 3207 and forgets any knowledge obtained from the server not
9724 obtained from the TLS negotiation itself. Patch contributed by Bill
9725 Fenner.
Gregory P. Smith2b3ba582008-01-17 08:03:17 +00009726
Georg Brandl3ee81df2008-05-17 18:14:43 +00009727- Issue #1339: The smtplib.SMTP class has been refactored a bit such
Gregory P. Smithbde4ae42008-01-17 08:35:49 +00009728 that the SMTP.starttls() caller no longer needs to call ehlo()
9729 beforehand. SMTP.starttls() now raises an exception of the server
Georg Brandl3ee81df2008-05-17 18:14:43 +00009730 does not claim to support starttls. Adds the
9731 SMTP.ehlo_or_helo_if_needed() method. Patch contributed by Bill
9732 Fenner.

Georg Brandl3ee81df2008-05-17 18:14:43 +00009774- Patch #976880: ``mmap`` objects now have an ``rfind`` method that
Andrew M. Kuchling5c60bfc2008-01-19 18:18:41 +00009775 works as expected. ``mmap.find`` also takes an optional ``end``
9776 parameter.

9801 contents before adding elements from the iterable. This fix brings
9802 the behavior into line with that for list.__init__().
Raymond Hettingeradf9ffd2007-12-13 00:08:37 +00009803
Georg Brandl3ee81df2008-05-17 18:14:43 +00009804- Added wide char functions to msvcrt module: getwch, getwche, putwch

9810
Georg Brandl3ee81df2008-05-17 18:14:43 +00009811- Marshal.dumps() now expects exact type matches for int, long, float,
9812 complex, tuple, list, dict, set, and frozenset. Formerly, it would
9813 silently miscode subclasses of those types. Now, it raises a
9814 ValueError instead.
Raymond Hettinger12e94202007-11-07 01:13:09 +00009815

Georg Brandl3ee81df2008-05-17 18:14:43 +00009830 time so that opening a database previously created with the DB_DUP
9831 or DB_DUPSORT flag set will keep the proper behavior on subsequent
9832 opens. Specifically: dictionary assignment to a DB object will
9833 replace all values for a given key when the database allows
9834 duplicate values. DB users should use DB.put(k, v) when they want
9835 to store duplicates; not DB[k] = v.
Gregory P. Smithec10a4a2007-11-05 02:32:26 +00009836

9842 characters with ASCII value less than 32. Also, it correctly quotes
9843 dots only if they occur on a single line, as opposed to the previous
9844 behavior of quoting dots if they are the second character of any
9845 line.
Georg Brandl4aef7272007-03-13 22:49:43 +00009846

Georg Brandl3ee81df2008-05-17 18:14:43 +000010237- Patch #1706: Drop support for Win9x, WinME and NT4. Python now
10238 requires Windows 2000 or greater. The _WINVER and NTDDI_VERSION

Georg Brandl3ee81df2008-05-17 18:14:43 +000010254- Removed the macfs module. It had been deprecated since Python 2.5.
10255 This lead to the deprecation of macostools.touched() as it relied
10256 solely on macfs and was a no-op under OS X.
