9Core and Builtins
10-----------------
11

20 is modified during the lifetime of the Python process after zipimport has
21 already cached the zip's table of contents we detect this and recover
22 rather than read bad data from the .zip (causing odd import errors).
23

32 state. Fix a crash when a generator is created in a C thread that is
33 destroyed while the generator is still used. The issue was that a generator
34 contains a frame, and the frame kept a reference to the Python state of the

602 options like -fwrapv were overridden and thus not used, which could result
603 in broken interpreters when building with clang.

1651 32-bit-only installer Pythons on systems with Xcode 4 (currently
1652 OS X 10.8, 10.7, and optionally 10.6).
1653 * Backport 3.3.0 fixes to 2.7 branch (for release in 2.7.4)
1654 * Since Xcode 4 removes ppc support, extension module builds now
1655 check for ppc compiler support and by default remove ppc and
1656 ppc64 archs when they are not available.
1657 * Extension module builds now revert to using system installed
1658 headers and libs (/usr and /System/Library) if the SDK used
1659 to build the interpreter is not installed or has moved.
1660 * Try to avoid building extension modules with deprecated
1661 and problematic Apple llvm-gcc compiler. If original compiler
1662 is not available, use clang instead by default.

Florent Xiclunac2279652012-02-12 14:49:03 +01002086- Issue #13994: Earlier partial revert of Distutils enhancements in 2.7
Ned Deilyc47a4592012-02-11 20:40:24 +01002087 has left two versions of customize_compiler, the original in
2088 distutils.sysconfig and another copy in distutils.ccompiler, with some
2089 parts of distutils calling one and others using the other.

2091 is the case in 3.x.

Ned Deily0d0ea482012-02-10 12:59:06 +01002093- Issue #13590: On OS X 10.7 and 10.6 with Xcode 4.2, building
2094 Distutils-based packages with C extension modules may fail because
2095 Apple has removed gcc-4.2, the version used to build python.org
2096 64-bit/32-bit Pythons. If the user does not explicitly override
2097 the default C compiler by setting the CC environment variable,
2098 Distutils will now attempt to compile extension modules with clang
2099 if gcc-4.2 is required but not found. Also as a convenience, if
2100 the user does explicitly set CC, substitute its value as the default
2101 compiler in the Distutils LDSHARED configuration variable for OS X.
2102 (Note, the python.org 32-bit-only Pythons use gcc-4.0 and the 10.4u
2103 SDK, neither of which are available in Xcode 4. This change does not
2104 attempt to override settings to support their use with Xcode 4.)

Ned Deily87e82bb2011-06-28 19:52:59 -07002354- Issue #9516: On Mac OS X, change Distutils to no longer globally attempt to
2355 check or set the MACOSX_DEPLOYMENT_TARGET environment variable for the
2356 interpreter process. This could cause failures in non-Distutils subprocesses
2357 and was unreliable since tests or user programs could modify the interpreter
Ezio Melotti302ad8d2013-01-19 19:44:58 +02002358 environment after Distutils set it. Instead, have Distutils set the
Ned Deily87e82bb2011-06-28 19:52:59 -07002359 deployment target only in the environment of each build subprocess. It is
2360 still possible to globally override the default by setting
2361 MACOSX_DEPLOYMENT_TARGET before launching the interpreter; its value must be
2362 greater or equal to the default value, the value with which the interpreter
2363 was built.

2393 the ticker doesn't have to wind down to zero from the old starting point
2394 before the new interval takes effect. And if the user increases the
2395 interval, it makes sure the new limit takes effect right away rather have an
2396 early task switch before recognizing the new interval.

Mark Dickinsoncb61e5d2010-09-26 10:37:12 +00003221- Issue #9869: Make long() and PyNumber_Long return something of type
3222 long for a class whose __long__ method returns a plain int. This
3223 fixes an interpreter crash when initializing an instance of a long

Antoine Pitrou0a7b65b2010-09-08 12:40:49 +00003228- Issue #9797: pystate.c wrongly assumed that zero couldn't be a valid
3229 thread-local storage key.
3230
Victor Stinnercaafd772010-09-08 10:51:01 +00003231- Issue #4947: The write() method of sys.stdout and sys.stderr uses their
3232 encoding and errors attributes instead of using utf-8 in strict mode, to get
3233 the same behaviour than the print statement.
3234
Antoine Pitrou9cf85f12010-09-01 21:17:34 +00003235- Issue #9737: Fix a crash when trying to delete a slice or an item from

3248 output with no type specifier failed to match the str output:
3249
3250 - format(complex(-0.0, 2.0), '-') omitted the real part from the output,
3251 - format(complex(0.0, 2.0), '-') included a sign and parentheses.
3252

3365 unhelpful TypeError when called on an unconnected socket. Original patch
3366 by Andrew Bennetts.
3367
Raymond Hettinger74f869e2010-09-13 22:14:36 +00003368- Issue #9826: OrderedDict.__repr__ can now handle self-referential

Antoine Pitroue4195e82010-09-12 14:56:27 +00003373- Issue #9837: The read() method of ZipExtFile objects (as returned by

3375
Raymond Hettinger20397532010-09-12 02:11:45 +00003376- Issue #9825: removed __del__ from the definition of collections.OrderedDict.
3377 This prevents user-created self-referencing ordered dictionaries from
3378 becoming permanently uncollectable GC garbage. The downside is that
3379 removing __del__ means that the internal doubly-linked list has to wait for
3380 GC collection rather than freeing memory immediately when the refcnt drops
3381 to zero.
3382
Raymond Hettingerffd2a422010-09-10 10:47:22 +00003383- Issue #9816: random.Random.jumpahead(n) did not produce a sufficiently

3386
Antoine Pitrouc818ed42010-09-07 21:40:25 +00003387- Issue #9792: In case of connection failure, socket.create_connection()
3388 would swallow the exception and raise a new one, making it impossible
3389 to fetch the original errno, or to filter timeout errors. Now the
3390 original error is re-raised.
3391
Antoine Pitrouf4f61712010-09-07 16:34:47 +00003392- Issue #9758: When fcntl.ioctl() was called with mutable_flag set to True,
3393 and the passed buffer was exactly 1024 bytes long, the buffer wouldn't
3394 be updated back after the system call. Original patch by Brian Brazil.
3395
Antoine Pitroudca9de92010-09-04 17:52:26 +00003396- Issue #1100562: Fix deep-copying of objects derived from the list and

Daniel Stutzbach66c981b2010-08-31 20:29:39 +00003402- Issue #808164: Fixed socket.close to avoid references to globals, to

3410 falling into recursion.
3411
R. David Murray7c4bf552010-08-25 01:45:57 +00003412- Issue #1194222: email.utils.parsedate now returns RFC2822 compliant four
3413 character years even if the message contains RFC822 two character years.
3414
Daniel Stutzbach91287322010-08-24 21:09:30 +00003415- Issue #8750: Fixed MutableSet's methods to correctly handle

3427 module now correctly return a set. (Patch by Eli Bendersky.)
3428
Antoine Pitrou3ebaed62010-08-21 19:17:25 +00003429- Issue #9617: Signals received during a low-level write operation aren't
3430 ignored by the buffered IO layer anymore.
3431
Benjamin Peterson52c36052010-08-21 03:03:22 +00003432- Issue #2521: Use weakrefs on for caching in the abc module, so that classes

3434
Raymond Hettingera54b2da2010-08-17 19:03:06 +00003435- Issue #9626: the view methods for collections.OrderedDict() were returning

3440 comment indicating they are generated. Manually maintained MANIFESTs
3441 without this marker will not be overwritten or removed.
3442
Antoine Pitroue1436d12010-08-12 15:25:51 +00003443- Issue #7467: when reading a file from a ZIP archive, its CRC is checked
3444 and a BadZipfile error is raised if it doesn't match (as used to be the
3445 case in Python 2.5 and earlier).
3446
Antoine Pitroucb4f47c2010-08-11 13:40:17 +00003447- Issue #9550: a BufferedReader could issue an additional read when the

3449 when the underlying raw IO channel was e.g. a socket. Report and original
3450 patch by Jason V. Miller.
3451
Fred Drake0a1fa0e2010-08-10 13:09:54 +00003452- Issue #9551: Don't raise TypeError when setting the value to None for

3838
Ezio Melottiab2eb0e2010-06-05 19:21:32 +00003839- Issue #8271: during the decoding of an invalid UTF-8 byte sequence, only the
3840 start byte and the continuation byte(s) are now considered invalid, instead
3841 of the number of bytes specified by the start byte.
3842 E.g.: '\xf1\x80AB'.decode('utf-8', 'replace') now returns u'\ufffdAB' and
3843 replaces with U+FFFD only the start byte ('\xf1') and the continuation byte
3844 ('\x80') even if '\xf1' is the start byte of a 4-bytes sequence.
3845 Previous versions returned a single u'\ufffd'.

3849 arises from the "Overriding __eq__ blocks inheritance ..." warning
3850 when turned into an exception: in this case the exception simply
3851 gets ignored.
Mark Dickinson23f0d6b2010-06-05 11:52:24 +00003852
Mark Dickinson4ca7c3c2010-05-30 13:18:10 +00003853- Issue #8748: Fix two issues with comparisons between complex and integer
3854 objects. (1) The comparison could incorrectly return True in some cases
3855 (2**53+1 == complex(2**53) == 2**53), breaking transivity of equality.
3856 (2) The comparison raised an OverflowError for large integers, leading
3857 to unpredictable exceptions when combining integers and complex objects
3858 in sets or dicts.
3859
Mark Dickinson81336372010-05-30 12:12:25 +00003860- Issue #5211: Implicit coercion for the complex type is now completely
3861 removed. (Coercion for arithmetic operations was already removed in 2.7
3862 alpha 4, but coercion for rich comparisons was accidentally left in.)
3863
Victor Stinnerc49dfcc2010-05-25 22:30:32 +00003864- Issue #3798: Write sys.exit() message to sys.stderr to use stderr encoding
3865 and error handler, instead of writing to the C stderr file in utf-8
3866
Georg Brandlfee0f442010-05-22 21:26:21 +00003867- Issue #7902: When using explicit relative import syntax, don't try implicit
3868 relative import semantics.

4052 operation raises multiple signals and more than one of those signals is
4053 trapped, the specification determines the order in which the signals should be

4241 with a non-empty format string. This is an effort to future-proof user
4242 code. If a derived class does not currently implement __format__ but later
4243 adds its own __format__, it would most likely break user code that had
Antoine Pitrou01a196a2011-01-02 20:05:11 +00004244 supplied a format string. This will be changed to a DeprecationWarning in
Georg Brandlfee0f442010-05-22 21:26:21 +00004245 Python 3.3 and it will be an error in Python 3.4.

Georg Brandlfee0f442010-05-22 21:26:21 +00004278- Issue #8257: The Decimal construct now accepts a float instance directly,
4279 converting that float to a Decimal of equal value:
Mark Dickinson8a950712010-04-03 15:47:46 +00004280
4281 >>> Decimal(1.1)
4282 Decimal('1.100000000000000088817841970012523233890533447265625')
4283

Georg Brandlfee0f442010-05-22 21:26:21 +00004295- Issue #7279: Comparisons involving a Decimal signaling NaN now signal
4296 InvalidOperation instead of returning False. (Comparisons involving a quiet
4297 NaN are unchanged.) Also, Decimal quiet NaNs are now hashable; Decimal
4298 signaling NaNs remain unhashable.

Georg Brandlfee0f442010-05-22 21:26:21 +00004300- Issue #2531: Comparison operations between floats and Decimal instances now
4301 return a result based on the numeric values of the operands; previously they
4302 returned an arbitrary result based on the relative ordering of id(float) and
4303 id(Decimal).

Barry Warsawf7f2d6f2010-03-31 21:07:16 +00004305- Issue #8233: When run as a script, py_compile.py optionally takes a single
Georg Brandlfee0f442010-05-22 21:26:21 +00004306 argument `-` which tells it to read files to compile from stdin. Each line is
4307 read on demand and the named file is compiled immediately. (Original patch by
4308 Piotr Ożarowski).

Georg Brandlfee0f442010-05-22 21:26:21 +00004317- Comparisons using one of <, <=, >, >= between a complex instance and a
4318 Fractions instance now raise TypeError instead of returning True/False. This
4319 makes Fraction <=> complex comparisons consistent with int <=> complex, float
4320 <=> complex, and complex <=> complex comparisons.

4420 integer format code, struct.pack first attempts to convert the non-integer

Georg Brandlba83f822010-03-14 09:50:54 +00004424- Issue #1530559: When passing a non-integer argument to struct.pack with *any*
4425 integer format code (one of 'bBhHiIlLqQ'), struct.pack attempts to use the
4426 argument's __int__ method to convert to an integer before packing. It also
Georg Brandlfee0f442010-05-22 21:26:21 +00004427 produces a DeprecationWarning in this case. (In Python 2.6, the behaviour was
4428 inconsistent: __int__ was used for some integer codes but not for others, and
4429 the set of integer codes for which it was used differed between native packing
4430 and standard packing.)

Antoine Pitrouf3fa0742010-01-31 22:26:04 +00004737- Issue #6939: Fix file I/O objects in the `io` module to keep the original
Georg Brandlba83f822010-03-14 09:50:54 +00004738 file position when calling `truncate()`. It would previously change the file
4739 position to the given argument, which goes against the tradition of
Antoine Pitrouf3fa0742010-01-31 22:26:04 +00004740 ftruncate() and other truncation APIs. Patch by Pascal Chambon.

Georg Brandlba83f822010-03-14 09:50:54 +00004742- Issue #7610: Reworked implementation of the internal ``zipfile.ZipExtFile``
4743 class used to represent files stored inside an archive. The new
4744 implementation is significantly faster and can be wrapped in a
4745 ``io.BufferedReader`` object for more speedups. It also solves an issue
4746 where interleaved calls to ``read()`` and ``readline()`` give wrong results.

4759 encoded string for them. This ensures that the upload and register commands
4760 send the correct values to PyPI without any error.

4835-----------------
4836
Georg Brandlba83f822010-03-14 09:50:54 +00004837- The ``__complex__()`` method is now looked up on the class of instances to
4838 make it consistent with other special methods.

4842
Mark Dickinson1b34d252010-01-01 17:27:30 +00004843- Issue #5080: A number of functions and methods previously produced a
Georg Brandlba83f822010-03-14 09:50:54 +00004844 DeprecationWarning when passed a float argument where an integer was expected.
4845 These functions and methods now raise TypeError instead. The majority of the
4846 effects of this change are in the extension modules, but some core functions
4847 and methods are affected: notably the 'chr', 'range' and 'xrange' builtins,
4848 and many unicode/str methods.

4862 of integers: the result of a/b is now correctly rounded for ints a and b (at
4863 least on IEEE 754 platforms), and in particular does not depend on the
4864 internal representation of a long.

Georg Brandlba83f822010-03-14 09:50:54 +00004873 These executables now work properly with the arch(1) command: ``arch -ppc

Georg Brandlba83f822010-03-14 09:50:54 +00005012- Issue #3382: 'F' formatting for float and complex now convert the result to
5013 upper case. This only affects 'inf' and 'nan', since 'f' no longer converts
5014 to 'g' for large values.
Amaury Forgeot d'Arcd7288712009-12-01 21:51:04 +00005015
Georg Brandlba83f822010-03-14 09:50:54 +00005016- Remove switch from "%f" formatting to "%g" formatting for floats larger than
5017 1e50 in absolute value.
Mark Dickinson9dd5e162009-11-23 20:54:09 +00005018
Georg Brandlba83f822010-03-14 09:50:54 +00005019- Remove restrictions on precision when formatting floats. E.g., "%.120g" %
5020 1e-100 used to raise OverflowError, but now gives the requested 120
5021 significant digits instead.
Mark Dickinson18cfada2009-11-23 18:46:41 +00005022

5028 10.6.
Ronald Oussoren315cd0c2009-11-19 16:25:21 +00005029
Georg Brandlba83f822010-03-14 09:50:54 +00005030- Issue #7117: ``repr(x)`` for a float x returns a result based on the shortest
5031 decimal string that's guaranteed to round back to x under correct rounding
5032 (with round-half-to-even rounding mode). Previously it gave a string based on
5033 rounding x to 17 decimal digits. repr(x) for a complex number behaves
5034 similarly. On platforms where the correctly-rounded strtod and dtoa code is
5035 not supported (see below), repr is unchanged.
Mark Dickinsonb678de82009-11-19 18:41:49 +00005036
Georg Brandlba83f822010-03-14 09:50:54 +00005037- Issue #7117: On almost all platforms: float-to-string and string-to-float
5038 conversions within Python are now correctly rounded. Places these conversions
5039 occur include: str for floats and complex numbers; the float and complex
5040 constructors; old-style and new-style numeric formatting; serialization and
5041 deserialization of floats and complex numbers using marshal, pickle and json;
5042 parsing of float and imaginary literals in Python code; Decimal-to-float
5043 conversion.
Mark Dickinsonb678de82009-11-19 18:41:49 +00005044
Georg Brandlba83f822010-03-14 09:50:54 +00005045 The conversions use a Python-adapted version of David Gay's well-known dtoa.c,
5046 providing correctly-rounded strtod and dtoa C functions. This code is
5047 supported on Windows, and on Unix-like platforms using gcc, icc or suncc as
5048 the C compiler. There may be a small number of platforms on which correct
5049 operation of this code cannot be guaranteed, so the code is not used: notably,
5050 this applies to platforms where the C double format is not IEEE 754 binary64,
5051 and to platforms on x86 hardware where the x87 FPU is set to 64-bit precision
5052 and Python's configure script is unable to determine how to change the FPU
5053 precision. On these platforms conversions use the platform strtod and dtoa,
5054 as before.
Mark Dickinsonb678de82009-11-19 18:41:49 +00005055
Georg Brandlba83f822010-03-14 09:50:54 +00005056- Issue #7117: Backport round implementation from Python 3.x. ``round()`` now
5057 uses the correctly-rounded string <-> float conversions described above (when
5058 available), and so produces correctly rounded results that will display nicely
5059 under the float repr. There are two related small changes: (1) round now
5060 accepts any class with an ``__index__()`` method for its second argument (but
5061 no longer accepts floats for the second argument), and (2) an excessively
5062 large second integer argument (e.g., ``round(1.234, 10**100)``) no longer
5063 raises an exception.

5066
Georg Brandlba83f822010-03-14 09:50:54 +00005067- Fix several issues with ``compile()``. The input can now contain Windows and

Georg Brandlba83f822010-03-14 09:50:54 +00005210- Issue #5920: For ``float.__format__()``, change the behavior with the empty
5211 presentation type (that is, not one of 'e', 'f', 'g', or 'n') to be like 'g'
5212 but with at least one decimal point and with a default precision
5213 of 12. Previously, the behavior the same but with a default precision of 6.
5214 This more closely matches ``str()``, and reduces surprises when adding
5215 alignment flags to the empty presentation type. This also affects the new
5216 complex.__format__ in the same way.
5217
5218- Issue #5890: In subclasses of 'property' the __doc__ attribute was shadowed by
5219 classtype's, even if it was None. property now inserts the __doc__ into the

Georg Brandlba83f822010-03-14 09:50:54 +00005440- On windows, ``os.chdir()`` given unicode was not working if

5442 this code path is really executed because I cannot move to such directory on
5443 win2k)

Georg Brandlba83f822010-03-14 09:50:54 +00005445- Issue #4069: When ``set.remove(element)`` is used with a set element, the
5446 element is temporarily replaced with an equivalent frozenset. But the
5447 eventual KeyError would always report the empty ``frozenset()`` as the missing
5448 key. Now it correctly refers to the initial element.

Georg Brandlba83f822010-03-14 09:50:54 +00006705 leak-chasing test runs give sensible results. The previous method of reaping
6706 threads could return successfully while some Thread objects were still
6707 referenced. This also introduces a new private function: ``thread._count()``.

6846
Martin v. Löwis9fa5a282008-09-11 06:53:30 +00006847- Issue #3642: Suppress warning in obmalloc when size_t is larger than uint.
6848
Amaury Forgeot d'Arc05e34492008-09-10 22:04:45 +00006849- Issue #3743: In a few places, PY_FORMAT_SIZE_T was incorrectly used with
6850 PyString_FromFormat or PyErr_Format to display size_t values. The macro
6851 PY_FORMAT_SIZE_T is designed to select the correct format for the OS
6852 ``printf`` function, whereas PyString_FromFormat has an independent
6853 implementation and uses "%zd" on all platforms for size_t values.
6854 This makes a difference on win64, where ``printf`` needs "%Id" to display
6855 64bit values.
6856
Benjamin Peterson97179b02008-09-09 20:55:01 +00006857- Issue #3634: _weakref.ref(Exception).__init__() gave invalid return value on
6858 error.
6859
Amaury Forgeot d'Arcd3ffb892008-09-09 07:24:30 +00006860- Issue #3777: long() applied to a float object now always return a long
6861 object; previously an int would be returned for small values. the __long__
6862 method is allowed to return either an int or a long, but the behaviour of
6863 float objects should not change to respect backward compatibility.
6864
Amaury Forgeot d'Arc3571fbf2008-09-01 19:52:00 +00006865- Issue #3751: str.rpartition would perform a left-partition when called with
6866 a unicode argument.
6867
Benjamin Peterson17f03ca2008-09-01 14:18:30 +00006868- Issue #3683: Fix compilation when --without-threads is given.
6869
Antoine Pitroud4ae97b2008-08-29 18:39:48 +00006870- Issue #3668: Fix a memory leak with the "s*" argument parser in
Vinay Sajip35e3b032008-09-01 14:33:59 +00006871 PyArg_ParseTuple and friends, which occurred when the argument for "s*"
Antoine Pitroud4ae97b2008-08-29 18:39:48 +00006872 was correctly parsed but parsing of subsequent arguments failed.
6873
Vinay Sajip35e3b032008-09-01 14:33:59 +00006874- Issue #2534: speed up isinstance() and issubclass() by 50-70%, so as to
Antoine Pitrou0668c622008-08-26 22:42:08 +00006875 match Python 2.5 speed despite the __instancecheck__ / __subclasscheck__
6876 mechanism. In the process, fix a bug where isinstance() and issubclass(),
6877 when given a tuple of classes as second argument, were looking up
6878 __instancecheck__ / __subclasscheck__ on the tuple rather than on each
6879 type object.
6880
Neal Norwitz18aa3882008-08-24 05:04:52 +00006881- Fix crashes on memory allocation failure found with failmalloc.
6882
6883- Fix memory leaks found with valgrind and update suppressions file.
6884
6885- Fix compiler warnings in opt mode which would lead to invalid memory reads.
6886
6887- Fix problem using wrong name in decimal module reported by pychecker.
6888
Christian Heimes7d4c3172008-08-22 19:47:25 +00006889- Silenced another compiler warning about a used but not defined
6890 function 'stringlib_contains_obj'.

Benjamin Peterson712ee922008-08-24 18:10:20 +00006892- Added warnings on the use of ``__getslice__``, ``__setslice__``, or
6893 ``__delslice__``.
6894
Gregory P. Smith2bb25cc2008-09-02 05:29:51 +00006895- Issue #3678: Correctly pass LDFLAGS and LDLAST to the linker on shared
6896 library targets in the Makefile.
6897
Gregory P. Smith980b99b2008-09-07 05:15:18 +00006898- Issue #1204: The configure script now tests for additional libraries
6899 that may be required when linking against readline. This fixes issues
6900 with x86_64 builds on some platforms (a few Linux flavors and OpenBSD).

Brett Cannon1eaf0742008-09-02 01:25:16 +00006950 warnings.catch_warnings() along with some API cleanup. Expanding the tests
6951 for catch_warnings() also led to an improvement in the raising of a
6952 DeprecationWarning related to warnings.warn_explicit().
6953
Benjamin Peterson973e6c22008-09-01 23:12:58 +00006954- The deprecation warnings for the old camelCase threading API were removed.

Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00007018What's New in Python 2.6 beta 3?
7019================================
7020
Barry Warsaw07a4a382008-08-21 01:15:08 +00007021*Release date: 20-Aug-2008*
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00007022
7023Core and Builtins
7024-----------------
7025
Guido van Rossumf8402962008-08-20 15:01:50 +00007026- Issue #1878: Remove Py_TPFLAGS_HAVE_VERSION_TAG from
7027 Py_TPFLAGS_DEFAULT when not building the core. This means 3rd party
7028 extensions do not automatically benefit from the class attribute
7029 cache; they will have to explicitly add Py_TPFLAGS_HAVE_VERSION_TAG
7030 to their tp_flags field if they care. This is a backwards
7031 compatibility feature; in 3.0, all types will use the cache by
7032 default.
7033
Benjamin Petersonf647dc12008-08-20 01:27:30 +00007034- Keyword arguments can now follow starred arguments. (``f(a, *args,
7035 keyword=23)`` is now valid syntax.)
7036
Thomas Heller0ad5ae02008-08-19 19:25:04 +00007037- ctypes function pointers that are COM methods have a boolean True
7038 value again.
7039
Martin v. Löwisf91d46a2008-08-12 14:49:50 +00007040- Issue #3139: Make buffer-interface thread-safe wrt. PyArg_ParseTuple,
7041 by denying s# to parse objects that have a releasebuffer procedure,
7042 and introducing s*.
7043
Georg Brandl1e13ea92008-08-11 09:07:59 +00007044- Issue #3537: Fix an assertion failure when an empty but presized dict
7045 object was stored in the freelist.
7046
Mark Dickinsonb6467572008-08-04 21:30:09 +00007047- Issue #1481296: Make long(float('nan')) and int(float('nan')) raise
7048 ValueError consistently across platforms.
7049
Amaury Forgeot d'Arc39fd6722008-07-31 21:28:03 +00007050- Issue #3479: On platforms where sizeof(int) is smaller than sizeof(long)
7051 (64bit Unix, for example), unichr() would truncate its argument and return
7052 u'\x00' for unichr(2**32). Now it properly raises an OverflowError.
7053
Neal Norwitze7d8be82008-07-31 17:17:14 +00007054- Apply security patches from Apple.
7055
Amaury Forgeot d'Arc246daed2008-07-31 00:42:16 +00007056- Issue #2542: Now that issubclass() may call arbitrary code, ensure that
7057 PyErr_ExceptionMatches returns 0 when an exception occurs there.
7058
Antoine Pitrou92f82162008-07-25 22:22:08 +00007059- Issue #1819: function calls with several named parameters are now on
7060 average 35% faster (as measured by pybench).
7061
Amaury Forgeot d'Arce4921fe2008-07-21 22:00:38 +00007062- Issue #2378: An unexpected UnboundLocalError or NameError could appear when
7063 the python debugger steps into a class statement: the free variables (local
7064 variables defined in an outer scope) would be deleted from the outer scope.
7065
Gregory P. Smith0470bab2008-07-22 04:46:32 +00007066- Issue #2620: Overflow checking when allocating or reallocating memory
7067 was not always being done properly in some python types and extension
7068 modules. PyMem_MALLOC, PyMem_REALLOC, PyMem_NEW and PyMem_RESIZE have
7069 all been updated to perform better checks and places in the code that
7070 would previously leak memory on the error path when such an allocation
7071 failed have been fixed.

7077
Benjamin Petersone977ad42008-08-20 01:42:01 +00007078- The methods ``is_in_tuple()``, ``is_vararg()``, and ``is_keywordarg()`` of
7079 symtable.Symbol have been deprecated for removal in 3.0 and the next release.
7080
Amaury Forgeot d'Arc351ffb82008-08-18 19:23:47 +00007081- Issue #2234: distutils failed for some versions of the cygwin compiler. The
7082 version reported by these tools does not necessarily follow the python
7083 version numbering scheme, so the module is less strict when parsing it.
7084
Nick Coghlanf70385a2008-08-18 12:42:46 +00007085- Issue #2235: Added Py3k warnings for types which will become unhashable
7086 under the stricter __hash__ inheritance rules in 3.0. Several types
7087 which did not meet the rules for hash invariants and were already
7088 unhashable in 3.0 have now been explicitly flagged as unhashable in
7089 2.6 as well (collections.Mapping, collections.Set, unittest.TestSuite,
7090 xml.dom.minidom.NamedNodeMap, numbers.Number, UserList.UserList)
7091
Brett Cannon88f801d2008-08-18 00:46:22 +00007092- Update __all__ for cookielib, csv, os, urllib2, and weakref to include things
7093 imported into the module but exposed as part of the module's API.
7094
Brett Cannon7b96f072008-08-18 00:41:11 +00007095- Remove an unneeded import of abc.ABCMeta from 'inspect'.

7100
Hirokazu Yamamoto41a81eb2008-08-17 13:10:46 +00007101- Issue #3575: Incremental decoder's decode function now takes bytearray
7102 by using 's*' instead of 't#'.
7103
Mark Dickinson3e4caeb2009-02-21 20:27:01 +00007104- Issue #2222: Fixed reference leak when occurred os.rename()
Hirokazu Yamamoto7f30a682008-08-17 09:46:56 +00007105 fails unicode conversion on 2nd parameter. (windows only)
7106
Georg Brandl222e2082010-08-01 22:27:39 +00007107- Issue #2464: urllib2 now supports a malformation in the URL received

Antoine Pitroude781a42008-08-09 12:43:23 +00007161 asking for a specific length. This problem only affected files opened

7205
Nick Coghlan2a0c2b12008-08-04 12:47:17 +00007206- Issue #643841: The language reference now provides more detailed

7219
Georg Brandl3e483f62008-07-16 22:57:41 +00007220- Issue #3156: Fix inconsistent behavior of the bytearray type: all
7221 its methods now allow for items objects that can be converted to
7222 an integer using operator.index().
7223
Mark Dickinson64b7e502008-07-16 09:40:03 +00007224- Issue #3360: Fix incorrect parsing of '020000000000.0', which
7225 produced a ValueError instead of giving the correct float.
7226
Eric Smitha5fa5a22008-07-16 00:11:49 +00007227- Issue #3083: Add alternate (#) formatting for bin, oct, hex output
7228 for str.format(). This adds the prefix 0b, 0o, or 0x, respectively.
7229
Mark Dickinson7103aa42008-07-15 19:08:33 +00007230- Issue #3008: the float type has a new instance method 'float.hex'
7231 and a new class method 'float.fromhex' to convert floating-point
7232 numbers to and from hexadecimal strings, respectively.
7233
Nick Coghlan6d6bd442008-07-15 15:40:22 +00007234- Issue #2235: __hash__ is once again inherited by default. To allow
7235 collections.Hashable to remain meaningful in the presence of the
7236 default hash implementation (object.__hash__), it is now possible
7237 to explicit block inheritance of hash by setting __hash__=None at
7238 the Python level, or tp_hash=PyObject_HashNotImplemented at the C
7239 level.
7240
Nick Coghlanb028f502008-07-13 14:52:36 +00007241- Issue #3221: Issue a RuntimeWarning instead of raising SystemError if
7242 the parent module cannot be found while performing an absolute import.
7243 This means that an incorrectly defined __package__ attribute will
7244 now only prevent relative imports in that module rather than causing
7245 all imports from that module to fail.
7246
Nick Coghlan14ff9942008-07-08 14:21:42 +00007247- Issue #2517: Allow unicode messages in Exceptions again by correctly

7257 another thread's dictionary.
7258
Mark Dickinson1ec2fcd2008-06-20 14:53:43 +00007259- Issue #3004: Minor change to slice.indices(): the start and stop
7260 arguments are now treated identically, making the behaviour easier
7261 to describe and understand. For example, slice(None, -10,
7262 1).indices(9) now returns (0, 0, 1) instead of (0, -1, 1), and
7263 slice(None, 10, -1).indices(10) returns (9, 9, -1) instead of (9,
7264 10, -1).

Georg Brandl278fc502008-07-19 12:46:12 +00007266- Issue #3219: Calling a function with repeated keyword arguments,
7267 f(a=2, a=23), would not cause a syntax error. This was a regression
7268 from 2.4 caused by the switch to the new compiler.

7307 both unnecessary (HTTP allows text content to be sent in several forms) and
Andrew M. Kuchlingcc3f2b12008-07-10 14:43:31 +00007308 wrong because the actual transmitted size could differ from the
Amaury Forgeot d'Arc0f7cddc2008-07-06 21:34:39 +00007309 content-length. The problem had been corrected in the 2.4 branch, but never

7711
Brett Cannonb61d8012008-05-11 23:39:04 +00007712- ``Lib/lib-old`` is now added to sys.path.
7713
Ronald Oussoren5640ce22008-06-05 12:58:24 +00007714- On MacOS X it is now possible to install the framework in 64-bit
7715 mode or even as a 4-way universal binary (that is, PPC, i386,
Georg Brandl5cc774e2008-06-11 20:28:06 +00007716 PPC64 and x86_64 support in one binary).
Ronald Oussoren5640ce22008-06-05 12:58:24 +00007717
7718 This is controlled by the configure argument ``--with-universal-archs``:
7719
7720 - ``--with-universal-archs=all``: install 4-way universal
7721
7722 - ``--with-universal-archs=32-bit``: install 2-way universal, 32-bit (the default)
7723
7724 - ``--with-universal-archs=64-bit``: install 2-way universal, 64-bit
7725
7726 This option should be used in combination with ``--enable-universalsdk=``.
7727
7728 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 +00007777- Issue #1631171: Re-implement the 'warnings' module in C (the
7778 original Python code has been kept as backup). This will allow for
7779 using the 'warning's machinery in such places as the parser where
7780 use of pure Python code is not possible. Both the ``showarning()``
7781 and ``formatwarning()`` gain an optional 'line' argument which is
7782 not called by default for backwards-compatibility reasons. Setting
7783 ``warnings.showwarning()`` to an implementation that lacks support
7784 for the ``line`` argument will raise a DeprecationWarning.

Georg Brandl3ee81df2008-05-17 18:14:43 +00007826- Issue #2513: distutils on Windows is now capable of cross-compiling
Mark Hammond495cf992008-04-07 01:53:39 +00007827 extension modules between 32 and 64 bit platforms. See the distutls

Georg Brandl3ee81df2008-05-17 18:14:43 +00007847- Issue #2550: The approach used by client/server code for obtaining
7848 ports to listen on in network-oriented tests has been refined in an
7849 effort to facilitate running multiple instances of the entire
7850 regression test suite in parallel without issue.
7851 test_support.bind_port() has been fixed such that it will always
7852 return a unique port -- which wasn't always the case with the
7853 previous implementation, especially if socket options had been set
7854 that affected address reuse (i.e. SO_REUSEADDR, SO_REUSEPORT). The
7855 new implementation of bind_port() will actually raise an exception
7856 if it is passed an AF_INET/SOCK_STREAM socket with either the
7857 SO_REUSEADDR or SO_REUSEPORT socket option set. Furthermore, if
7858 available, bind_port() will set the SO_EXCLUSIVEADDRUSE option on
7859 the socket it's been passed. This currently only applies to
7860 Windows. This option prevents any other sockets from binding to the
7861 host/port we've bound to, thus removing the possibility of the
7862 'non-deterministic' behaviour, as Microsoft puts it, that occurs
7863 when a second SOCK_STREAM socket binds and accepts to a host/port
7864 that's already been bound by another socket. The optional preferred
7865 port parameter to bind_port() has been removed. Under no
7866 circumstances should tests be hard coding ports!
7867
7868 test_support.find_unused_port() has also been introduced, which will
7869 pass a temporary socket object to bind_port() in order to obtain an
7870 unused port. The temporary socket object is then closed and
7871 deleted, and the port is returned. This method should only be used
7872 for obtaining an unused port in order to pass to an external program
7873 (i.e. the -accept [port] argument to openssl's s_server mode) or as
7874 a parameter to a server-oriented class that doesn't give you direct
7875 access to the underlying socket used.
7876
7877 Finally, test_support.HOST has been introduced, which should be used
7878 for the host argument of any relevant socket calls (i.e. bind and
7879 connect).
Trent Nelsone41b0062008-04-08 23:47:30 +00007880
7881 The following tests were updated to following the new conventions:
Georg Brandl3ee81df2008-05-17 18:14:43 +00007882 test_socket, test_smtplib, test_asyncore, test_ssl, test_httplib,
Trent Nelsone41b0062008-04-08 23:47:30 +00007883 test_poplib, test_ftplib, test_telnetlib, test_socketserver,
7884 test_asynchat and test_socket_ssl.
7885
Georg Brandl3ee81df2008-05-17 18:14:43 +00007886 It is now possible for multiple instances of the regression test
7887 suite to run in parallel without issue.

Eric Smitha73fbe72008-02-23 03:09:44 +00008166- Added the future_builtins module, which contains hex() and oct().
8167 These are the PEP 3127 version of these functions, designed to be
8168 compatible with the hex() and oct() builtins from Python 3.0. They
8169 differ slightly in their output formats from the existing, unchanged
8170 Python 2.6 builtins. The expected usage of the future_builtins
8171 module is:
8172 from future_builtins import hex, oct
8173
Eric Smith7ef40bf2008-02-20 23:34:22 +00008174- Issue #1600: Modifed PyOS_ascii_formatd to use at most 2 digit
8175 exponents for exponents with absolute value < 100. Follows C99
8176 standard. This is a change on Windows, which would use 3 digits.
8177 Also, added 'n' to the formats that PyOS_ascii_formatd understands,
8178 so that any alterations it does to the resulting string will be
8179 available in stringlib/formatter.h (for float.__format__).
8180
Eric Smith5a3c1352008-02-19 13:21:56 +00008181- Implemented PEP 3101, Advanced String Formatting. This adds a new
8182 builtin format(); a format() method for str and unicode; a
8183 __format__() method to object, str, unicode, int, long, float, and
8184 datetime; the class string.Formatter; and the C API
8185 PyObject_Format().
8186
Georg Brandl3ee81df2008-05-17 18:14:43 +00008187- Fixed several potential crashes, all caused by specially crafted
8188 __del__ methods exploiting objects in temporarily inconsistent
8189 state.

Georg Brandl3ee81df2008-05-17 18:14:43 +00008195- Fixed repr() and str() of complex numbers with infinity or nan as
8196 real or imaginary part.
Christian Heimes2f0da532008-02-15 06:57:08 +00008197
Georg Brandl3ee81df2008-05-17 18:14:43 +00008198- Clear all free lists during a gc.collect() of the highest generation
8199 in order to allow pymalloc to free more arenas. Python may give back
8200 memory to the OS earlier.
Christian Heimes3b718a72008-02-14 12:47:33 +00008201
Georg Brandl3ee81df2008-05-17 18:14:43 +00008202- Issue #2045: Fix an infinite recursion triggered when printing a
8203 subclass of collections.defaultdict, if its default_factory is set
8204 to a bound method.
Amaury Forgeot d'Arcb01aa432008-02-08 00:56:02 +00008205
Christian Heimesf75dbef2008-02-08 00:11:31 +00008206- Fixed a minor memory leak in dictobject.c. The content of the free
8207 list was not freed on interpreter shutdown.
8208
Georg Brandl21e99f42010-03-07 15:23:59 +00008209- Limit free list of method and built-in function objects to 256
Georg Brandl3ee81df2008-05-17 18:14:43 +00008210 entries each.
Christian Heimes6075a822008-02-06 12:44:34 +00008211
Georg Brandl3ee81df2008-05-17 18:14:43 +00008212- Patch #1953: Added ``sys._compact_freelists()`` and the C API
8213 functions ``PyInt_CompactFreeList`` and ``PyFloat_CompactFreeList``
Christian Heimes422051a2008-02-04 18:00:12 +00008214 to compact the internal free lists of pre-allocted ints and floats.
8215
Georg Brandl3ee81df2008-05-17 18:14:43 +00008216- Issue #1983: Fixed return type of fork(), fork1() and forkpty()
8217 calls. Python expected the return type int but the fork familie
8218 returns pi_t.
Christian Heimes951cc0f2008-01-31 23:08:23 +00008219
Georg Brandl3ee81df2008-05-17 18:14:43 +00008220- Issue #1678380: Fix a bug that identifies 0j and -0j when they
8221 appear in the same code unit.
Mark Dickinson105be772008-01-31 22:17:37 +00008222
Georg Brandl3ee81df2008-05-17 18:14:43 +00008223- Issue #2025: Add tuple.count() and tuple.index() methods to comply
8224 with the collections.Sequence API.
Raymond Hettinger5b07ebc2008-02-07 00:54:20 +00008225
Georg Brandl3ee81df2008-05-17 18:14:43 +00008226- Patch #1970 by Antoine Pitrou: Speedup unicode whitespace and
8227 linebreak detection

Georg Brandl3ee81df2008-05-17 18:14:43 +00008229- Added ``PyType_ClearCache()`` and ``sys._clear_type_cache`` to clear
8230 the internal lookup cache for ref leak tests.
Christian Heimes908caac2008-01-27 23:34:59 +00008231
Georg Brandl3ee81df2008-05-17 18:14:43 +00008232- Patch #1473257: generator objects gain a gi_code attribute. This is
8233 the same object as the func_code attribute of the function that
8234 produced the generator.
Georg Brandl0cdf9a32008-01-26 14:14:20 +00008235
Georg Brandl3ee81df2008-05-17 18:14:43 +00008236- Issue #1920: "while 0" statements were completely removed by the
8237 compiler, even in the presence of an "else" clause, which is
8238 supposed to be run when the condition is false. Now the compiler
8239 correctly emits bytecode for the "else" suite.
Amaury Forgeot d'Arc31eaafe2008-01-24 22:59:25 +00008240
Guido van Rossumeead05f2008-01-24 18:21:02 +00008241- A few crashers fixed: weakref_in_del.py (issue #1377858);
8242 loosing_dict_ref.py (issue #1303614, test67.py);
8243 borrowed_ref_[34].py (not in tracker).
8244
Vinay Sajipd7cf32e2008-01-24 12:43:33 +00008245- Issue #1069410: The "can't load dll" message box on Windows is
Christian Heimesb2302ba2008-01-23 17:15:06 +00008246 suppressed while an extension is loaded by calling SetErrorMode in
8247 dynload_win.c. The error is still reported properly.
8248
Georg Brandl3ee81df2008-05-17 18:14:43 +00008249- Issue #1915: Python compiles with --enable-unicode=no again. However
Christian Heimes082c9b02008-01-23 14:20:50 +00008250 several extension methods and modules do not work without unicode
8251 support.
8252
Georg Brandl26543b12008-01-21 18:36:51 +00008253- Issue #1882: when compiling code from a string, encoding cookies in the
8254 second line of code were not always recognized correctly.
8255
Georg Brandl14404b62008-01-19 19:27:05 +00008256- Issue #1679: "0x" was taken as a valid integer literal.
8257
Georg Brandl6caad7d2008-01-26 14:19:22 +00008258- Issue #1865: ``bytes`` as an alias for ``str`` and b"" as an alias "" were
Christian Heimes288e89a2008-01-18 18:24:07 +00008259 added.
8260
Christian Heimesc94e2b52008-01-14 04:13:37 +00008261- sys.float_info / PyFloat_GetInfo: The floating point information
8262 object was converted from a dict to a specialized structseq object.
8263
Georg Brandl3ee81df2008-05-17 18:14:43 +00008264- Patch #1816: Added sys.flags structseq. It exposes the status of
8265 most command line arguments and PYTHON* environment variables.
Christian Heimesf31b69f2008-01-14 03:42:48 +00008266
Georg Brandl3ee81df2008-05-17 18:14:43 +00008267- Objects/structseq.c: Implemented new structseq representation. The
8268 patch makes structseqs (e.g. the return value of os.stat) more
8269 readable.
Christian Heimes9c201962008-01-14 03:33:52 +00008270
Georg Brandl3ee81df2008-05-17 18:14:43 +00008271- Patch #1700288: added a type attribute cache that caches method
8272 accesses, resulting in speedups in heavily object-oriented code.
Amaury Forgeot d'Arce4c270c2008-01-14 00:29:41 +00008273
Neal Norwitz3fc15b82008-01-10 05:42:58 +00008274- Bug #1776: __import__() no longer accepts filenames on any platform.
8275 The first parameter to __import__() must be a valid module name.
Christian Heimes3403f152008-01-09 19:56:33 +00008276
Georg Brandlaed6c662008-01-07 17:25:53 +00008277- Patch #1668: renamed THREADDEBUG envvar to PYTHONTHREADDEBUG.
8278
Georg Brandl3ee81df2008-05-17 18:14:43 +00008279- Patch #602345: Add -B command line option, PYTHONDONTWRITEBYTECODE
8280 envvar and sys.dont_write_bytecode attribute. All these can be set
8281 to forbid Python to attempt to write compiled bytecode files.
Georg Brandl2da0fce2008-01-07 17:09:35 +00008282
Georg Brandl3ee81df2008-05-17 18:14:43 +00008283- Improve some exception messages when Windows fails to load an
8284 extension module. Now we get for example '%1 is not a valid Win32
8285 application' instead of 'error code 193'.
Amaury Forgeot d'Arce0b76952008-01-04 02:04:15 +00008286

8290 y) functions.
Christian Heimese2ca4242008-01-03 20:23:15 +00008291
Christian Heimes0a8143f2007-12-18 23:22:54 +00008292- Issue #1635: Platform independent creation and representation of NaN
Georg Brandl3ee81df2008-05-17 18:14:43 +00008293 and INF. float("nan"), float("inf") and float("-inf") now work on
8294 every platform with IEEE 754 semantics.
Christian Heimes0a8143f2007-12-18 23:22:54 +00008295
Georg Brandl3ee81df2008-05-17 18:14:43 +00008296- Compiler now generates simpler and faster code for dictionary
8297 literals. The oparg for BUILD_MAP now indicates an estimated
8298 dictionary size. There is a new opcode, STORE_MAP, for adding
8299 entries to the dictionary.

Georg Brandl3ee81df2008-05-17 18:14:43 +00008328- Patch #1739468: Directories and zipfiles containing a __main__.py
8329 file can now be directly executed by passing their name to the
8330 interpreter. The directory/zipfile is automatically inserted as the
8331 first entry in sys.path.
Nick Coghlan327a39b2007-11-18 11:56:28 +00008332
Georg Brandl3ee81df2008-05-17 18:14:43 +00008333- Issue #1265: Fix a problem with sys.settrace, if the tracing
8334 function uses a generator expression when at the same time the
8335 executed code is closing a paused generator.
Amaury Forgeot d'Arc0d75f092007-11-13 21:54:28 +00008336
Raymond Hettinger1760c8a2007-11-08 02:52:43 +00008337- sets and frozensets now have an isdisjoint() method.
8338
Raymond Hettinger3f8caa32007-10-24 01:28:33 +00008339- optimize the performance of builtin.sum().
8340
Neal Norwitz44f326e2007-10-05 05:29:17 +00008341- Fix warnings found by the new version of the Coverity checker.
8342
Georg Brandl21e99f42010-03-07 15:23:59 +00008343- The enumerate() built-in function is no longer bounded to sequences
Georg Brandl3ee81df2008-05-17 18:14:43 +00008344 smaller than LONG_MAX. Formerly, it raised an OverflowError. Now,
8345 automatically shifts from ints to longs.
Raymond Hettinger8f669372007-10-03 21:18:11 +00008346
Georg Brandl3ee81df2008-05-17 18:14:43 +00008347- Issue #1686386: Tuple's tp_repr did not take into account the
8348 possibility of having a self-referential tuple, which is possible
8349 from C code. Nor did object's tp_str consider that a type's tp_str
8350 could do something that could lead to an inifinite recursion.
8351 Py_ReprEnter() and Py_EnterRecursiveCall(), respectively, fixed the
8352 issues.
Brett Cannon0b14f242007-09-30 19:45:10 +00008353
Georg Brandl3ee81df2008-05-17 18:14:43 +00008354- Issue #1164: It was possible to trigger deadlock when using the
8355 'print' statement to write to a file since the GIL was not released
8356 as needed. Now PyObject_Print() does the right thing along with
8357 various tp_print implementations of the built-in types and those in
8358 the collections module.
Brett Cannon01531592007-09-17 03:28:34 +00008359
Georg Brandl3ee81df2008-05-17 18:14:43 +00008360- Issue #1147: Exceptions were directly allowing string exceptions in
8361 their throw() method even though string exceptions no longer
8362 allowed.
Brett Cannon4c20bc42007-09-11 21:02:28 +00008363
Georg Brandl3ee81df2008-05-17 18:14:43 +00008364- Issue #1096: Prevent a segfault from getting the repr of a very
8365 deeply nested list by using the recursion counter.
Brett Cannona0c05512007-09-10 21:38:27 +00008366
Brett Cannon1e534b52007-09-07 04:18:30 +00008367- Issue #1202533: Fix infinite recursion calls triggered by calls to
Georg Brandl3ee81df2008-05-17 18:14:43 +00008368 PyObject_Call() never calling back out to Python code to trigger
8369 recursion depth updates/checks. Required the creation of a static
8370 RuntimeError instance in case normalizing an exception put the
8371 recursion check value past its limit. Fixes crashers
8372 infinite_rec_(1|2|4|5).py.
Brett Cannon1e534b52007-09-07 04:18:30 +00008373

Neal Norwitz0ac60192007-05-27 04:08:54 +00008387- Add new attribute names for function objects. All the func_* become
Georg Brandl3ee81df2008-05-17 18:14:43 +00008388 __*__ attributes. (Some already existed, e.g., __doc__ and
8389 __name__.)
Neal Norwitz0ac60192007-05-27 04:08:54 +00008390
Neal Norwitz8b2bfbc2007-05-23 06:35:32 +00008391- Add -3 option to the interpreter to warn about features that are
8392 deprecated and will be changed/removed in Python 3.0.
8393
Georg Brandl2134e752007-05-21 20:34:16 +00008394- Patch #1686487: you can now pass any mapping after '**' in function
8395 calls.
8396
Collin Winter62903052007-05-18 23:11:24 +00008397- except clauses may now be spelled either "except E, target:" or
Georg Brandl3ee81df2008-05-17 18:14:43 +00008398 "except E as target:". This is to provide forwards compatibility
8399 with Python 3.0.

Brett Cannon229cee22007-05-05 01:34:02 +00008401- Deprecate BaseException.message as per PEP 352.
8402
Georg Brandl3ee81df2008-05-17 18:14:43 +00008403- Issue #1303614: don't expose object's __dict__ when the dict is
Georg Brandl21e99f42010-03-07 15:23:59 +00008404 inherited from a built-in base.

Vinay Sajip8549ce32007-05-06 17:53:37 +00008406- When __slots__ are set to a unicode string, make it work the same as
Neal Norwitzcbd9ee62007-04-14 05:25:50 +00008407 setting a plain string, ie don't expand to single letter identifiers.
8408
Raymond Hettinger13936692007-04-11 18:40:58 +00008409- Request #1191699: Slices can now be pickled.
8410
Raymond Hettinger4db5fe92007-04-12 04:10:00 +00008411- Request #1193128: str.translate() now allows a None argument for
8412 translations that only remove characters without re-mapping the
8413 remaining characters.
8414
Georg Brandl5cb76c12007-03-21 09:00:39 +00008415- Patch #1682205: a TypeError while unpacking an iterable is no longer
8416 masked by a generic one with the message "unpack non-sequence".
8417
Neal Norwitzaa754b72007-03-21 06:39:48 +00008418- Remove unused file Python/fmod.c.
8419
Guido van Rossum143b5642007-03-23 04:58:42 +00008420- Bug #1683368: The object.__init__() and object.__new__() methods are
8421 now stricter in rejecting excess arguments. The only time when
8422 either allows excess arguments is when it is not overridden and the
8423 other one is. For backwards compatibility, when both are
8424 overridden, it is a deprecation warning (for now; maybe a Py3k
Guido van Rossum234b1ff2007-03-23 19:39:01 +00008425 warning later). Also, type.__init__() insists on the same signature
8426 as supported by type.__new__().

Georg Brandl3ee81df2008-05-17 18:14:43 +00008428- Patch #1675423: PyComplex_AsCComplex() now tries to convert an
8429 object to complex using its __complex__() method before falling back
8430 to the __float__() method. Therefore, the functions in the cmath
8431 module now can operate on objects that define a __complex__()

Georg Brandl4e933132006-09-06 20:05:58 +00008571- Bug #1542051: Exceptions now correctly call PyObject_GC_UnTrack.

9481 complex, tuple, list, dict, set, and frozenset. Formerly, it would
9482 silently miscode subclasses of those types. Now, it raises a
9483 ValueError instead.
Raymond Hettinger12e94202007-11-07 01:13:09 +00009484

Georg Brandl3ee81df2008-05-17 18:14:43 +00009499 time so that opening a database previously created with the DB_DUP
9500 or DB_DUPSORT flag set will keep the proper behavior on subsequent
9501 opens. Specifically: dictionary assignment to a DB object will
9502 replace all values for a given key when the database allows
9503 duplicate values. DB users should use DB.put(k, v) when they want
9504 to store duplicates; not DB[k] = v.
Gregory P. Smithec10a4a2007-11-05 02:32:26 +00009505

9511 characters with ASCII value less than 32. Also, it correctly quotes
9512 dots only if they occur on a single line, as opposed to the previous
9513 behavior of quoting dots if they are the second character of any
9514 line.
Georg Brandl4aef7272007-03-13 22:49:43 +00009515
