571 This prevents user-created self-referencing ordered dictionaries from
572 becoming permanently uncollectable GC garbage. The downside is that
573 removing __del__ means that the internal doubly-linked list has to wait for
574 GC collection rather than freeing memory immediately when the refcnt drops
575 to zero.

Ezio Melottiab2eb0e2010-06-05 19:21:32 +00001034- Issue #8271: during the decoding of an invalid UTF-8 byte sequence, only the
1035 start byte and the continuation byte(s) are now considered invalid, instead
1036 of the number of bytes specified by the start byte.
1037 E.g.: '\xf1\x80AB'.decode('utf-8', 'replace') now returns u'\ufffdAB' and
1038 replaces with U+FFFD only the start byte ('\xf1') and the continuation byte
1039 ('\x80') even if '\xf1' is the start byte of a 4-bytes sequence.

Mark Dickinson4ca7c3c2010-05-30 13:18:10 +00001048- Issue #8748: Fix two issues with comparisons between complex and integer
1049 objects. (1) The comparison could incorrectly return True in some cases
1050 (2**53+1 == complex(2**53) == 2**53), breaking transivity of equality.
1051 (2) The comparison raised an OverflowError for large integers, leading
1052 to unpredictable exceptions when combining integers and complex objects
1053 in sets or dicts.

Mark Dickinson81336372010-05-30 12:12:25 +00001055- Issue #5211: Implicit coercion for the complex type is now completely

Georg Brandlfee0f442010-05-22 21:26:21 +00001435- Issue #7994: Issue a PendingDeprecationWarning if object.__format__ is called
1436 with a non-empty format string. This is an effort to future-proof user
1437 code. If a derived class does not currently implement __format__ but later
1438 adds its own __format__, it would most likely break user code that had
Antoine Pitrou01a196a2011-01-02 20:05:11 +00001439 supplied a format string. This will be changed to a DeprecationWarning in
Georg Brandlfee0f442010-05-22 21:26:21 +00001440 Python 3.3 and it will be an error in Python 3.4.

Mark Dickinson8efef5c2010-01-12 22:23:56 +00001888
Georg Brandlba83f822010-03-14 09:50:54 +00001889 (1) a serious 'wrong output' bug that could occur for long (> 40 digit) input
1890 strings,
1891 (2) a crash in dtoa.c that occurred in debug builds when parsing certain long
1892 numeric strings corresponding to subnormal values,
1893 (3) a memory leak for some values large enough to cause overflow, and
1894 (4) a number of flaws that could lead to incorrectly rounded results.

Georg Brandlba83f822010-03-14 09:50:54 +00001933 file position when calling `truncate()`. It would previously change the file
1934 position to the given argument, which goes against the tradition of
Antoine Pitrouf3fa0742010-01-31 22:26:04 +00001935 ftruncate() and other truncation APIs. Patch by Pascal Chambon.

1938 class used to represent files stored inside an archive. The new
1939 implementation is significantly faster and can be wrapped in a
1940 ``io.BufferedReader`` object for more speedups. It also solves an issue
1941 where interleaved calls to ``read()`` and ``readline()`` give wrong results.

Georg Brandlba83f822010-03-14 09:50:54 +00001952- Issue #7748: Since unicode values are supported for some metadata options in
1953 Distutils, the DistributionMetadata get_* methods will now return an utf-8
1954 encoded string for them. This ensures that the upload and register commands
1955 send the correct values to PyPI without any error.

2030-----------------
2031
Georg Brandlba83f822010-03-14 09:50:54 +00002032- The ``__complex__()`` method is now looked up on the class of instances to
2033 make it consistent with other special methods.

Antoine Pitrou5b7139a2010-01-02 21:12:58 +00002035- Issue #7462: Implement the stringlib fast search algorithm for the `rfind`,
2036 `rindex`, `rsplit` and `rpartition` methods. Patch by Florent Xicluna.
2037
Mark Dickinson1b34d252010-01-01 17:27:30 +00002038- Issue #5080: A number of functions and methods previously produced a
Georg Brandlba83f822010-03-14 09:50:54 +00002039 DeprecationWarning when passed a float argument where an integer was expected.
2040 These functions and methods now raise TypeError instead. The majority of the
2041 effects of this change are in the extension modules, but some core functions
2042 and methods are affected: notably the 'chr', 'range' and 'xrange' builtins,
2043 and many unicode/str methods.

2057 of integers: the result of a/b is now correctly rounded for ints a and b (at
2058 least on IEEE 754 platforms), and in particular does not depend on the
2059 internal representation of a long.

2067
Georg Brandlba83f822010-03-14 09:50:54 +00002068 These executables now work properly with the arch(1) command: ``arch -ppc
2069 python`` will start a universal binary version of python in PPC mode (unlike

2210 to 'g' for large values.
Amaury Forgeot d'Arcd7288712009-12-01 21:51:04 +00002211

Georg Brandlba83f822010-03-14 09:50:54 +00002226- Issue #7117: ``repr(x)`` for a float x returns a result based on the shortest
2227 decimal string that's guaranteed to round back to x under correct rounding
2228 (with round-half-to-even rounding mode). Previously it gave a string based on
2229 rounding x to 17 decimal digits. repr(x) for a complex number behaves
2230 similarly. On platforms where the correctly-rounded strtod and dtoa code is
2231 not supported (see below), repr is unchanged.
Mark Dickinsonb678de82009-11-19 18:41:49 +00002232
Georg Brandlba83f822010-03-14 09:50:54 +00002233- Issue #7117: On almost all platforms: float-to-string and string-to-float
2234 conversions within Python are now correctly rounded. Places these conversions
2235 occur include: str for floats and complex numbers; the float and complex
2236 constructors; old-style and new-style numeric formatting; serialization and
2237 deserialization of floats and complex numbers using marshal, pickle and json;
2238 parsing of float and imaginary literals in Python code; Decimal-to-float
2239 conversion.
Mark Dickinsonb678de82009-11-19 18:41:49 +00002240
Georg Brandlba83f822010-03-14 09:50:54 +00002241 The conversions use a Python-adapted version of David Gay's well-known dtoa.c,
2242 providing correctly-rounded strtod and dtoa C functions. This code is
2243 supported on Windows, and on Unix-like platforms using gcc, icc or suncc as
2244 the C compiler. There may be a small number of platforms on which correct
2245 operation of this code cannot be guaranteed, so the code is not used: notably,
2246 this applies to platforms where the C double format is not IEEE 754 binary64,
2247 and to platforms on x86 hardware where the x87 FPU is set to 64-bit precision
2248 and Python's configure script is unable to determine how to change the FPU
2249 precision. On these platforms conversions use the platform strtod and dtoa,
2250 as before.
Mark Dickinsonb678de82009-11-19 18:41:49 +00002251
Georg Brandlba83f822010-03-14 09:50:54 +00002252- Issue #7117: Backport round implementation from Python 3.x. ``round()`` now
2253 uses the correctly-rounded string <-> float conversions described above (when
2254 available), and so produces correctly rounded results that will display nicely
2255 under the float repr. There are two related small changes: (1) round now
2256 accepts any class with an ``__index__()`` method for its second argument (but
2257 no longer accepts floats for the second argument), and (2) an excessively
2258 large second integer argument (e.g., ``round(1.234, 10**100)``) no longer
2259 raises an exception.

Georg Brandlba83f822010-03-14 09:50:54 +00002402 (1) inf and nan strings with trailing whitespace were incorrectly rejected;
2403 (2) parsing of strings representing infinities and nans was locale aware; and
2404 (3) the interpretation of fromhex('-nan') didn't match that of float('-nan').

Georg Brandlba83f822010-03-14 09:50:54 +00002406- Issue #5920: For ``float.__format__()``, change the behavior with the empty
2407 presentation type (that is, not one of 'e', 'f', 'g', or 'n') to be like 'g'
2408 but with at least one decimal point and with a default precision
2409 of 12. Previously, the behavior the same but with a default precision of 6.
2410 This more closely matches ``str()``, and reduces surprises when adding
2411 alignment flags to the empty presentation type. This also affects the new
2412 complex.__format__ in the same way.
2413
2414- Issue #5890: In subclasses of 'property' the __doc__ attribute was shadowed by

Georg Brandlba83f822010-03-14 09:50:54 +00002595- Issue #4445: Replace ``sizeof(PyStringObject)`` with
2596 ``offsetof(PyStringObject, ob_sval) + 1`` when allocating memory for str
2597 instances. On a typical machine this saves 3 bytes of memory (on average) per
2598 string allocation.

Amaury Forgeot d'Arcdc619012008-11-22 20:01:18 +00002600- Issue #3996: On Windows, the PyOS_CheckStack function would cause the

2609
Georg Brandlba83f822010-03-14 09:50:54 +00002610- Issue #4233: Changed semantic of ``_fileio.FileIO``'s ``close()`` method on
2611 file objects with closefd=False. The file descriptor is still kept open but
2612 the file object behaves like a closed file. The ``FileIO`` object also got a
2613 new readonly attribute ``closefd``.

Georg Brandlba83f822010-03-14 09:50:54 +00002636- On windows, ``os.chdir()`` given unicode was not working if

2638 this code path is really executed because I cannot move to such directory on

Georg Brandlba83f822010-03-14 09:50:54 +00002641- Issue #4069: When ``set.remove(element)`` is used with a set element, the
2642 element is temporarily replaced with an equivalent frozenset. But the
2643 eventual KeyError would always report the empty ``frozenset()`` as the missing

Walter Dörwalded960ac2009-05-03 22:36:33 +00002664- Issue #5108: Handle %s like %S and %R in PyUnicode_FromFormatV(): Call
2665 PyUnicode_DecodeUTF8() once, remember the result and output it in a second
2666 step. This avoids problems with counting UTF-8 bytes that ignores the effect
2667 of using the replace error handler in PyUnicode_DecodeUTF8().
2668
Walter Dörwald726ba8e2009-05-06 14:32:35 +00002669- Issue #3739: The unicode-internal encoder now reports the number of characters

2671
Georg Brandlba83f822010-03-14 09:50:54 +00002672- Issue #2422: When compiled with the ``--with-valgrind`` option, the pymalloc
2673 allocator will be automatically disabled when running under Valgrind. This
2674 gives improved memory leak detection when running under Valgrind, while taking
2675 advantage of pymalloc at other times.

3842 __long__ method could be packed by 'q', 'Q', '*q', '*Q'; for x with
3843 neither __int__ nor __long__, TypeError used to be raised (with a

Martin v. Löwis9fa5a282008-09-11 06:53:30 +00004040- Issue #3642: Suppress warning in obmalloc when size_t is larger than uint.
4041
Amaury Forgeot d'Arc05e34492008-09-10 22:04:45 +00004042- Issue #3743: In a few places, PY_FORMAT_SIZE_T was incorrectly used with
4043 PyString_FromFormat or PyErr_Format to display size_t values. The macro
4044 PY_FORMAT_SIZE_T is designed to select the correct format for the OS
4045 ``printf`` function, whereas PyString_FromFormat has an independent
4046 implementation and uses "%zd" on all platforms for size_t values.
4047 This makes a difference on win64, where ``printf`` needs "%Id" to display
4048 64bit values.
4049
Benjamin Peterson97179b02008-09-09 20:55:01 +00004050- Issue #3634: _weakref.ref(Exception).__init__() gave invalid return value on

4054 object; previously an int would be returned for small values. the __long__
4055 method is allowed to return either an int or a long, but the behaviour of
4056 float objects should not change to respect backward compatibility.
4057
Amaury Forgeot d'Arc3571fbf2008-09-01 19:52:00 +00004058- Issue #3751: str.rpartition would perform a left-partition when called with

Vinay Sajip35e3b032008-09-01 14:33:59 +00004064 PyArg_ParseTuple and friends, which occurred when the argument for "s*"
Antoine Pitroud4ae97b2008-08-29 18:39:48 +00004065 was correctly parsed but parsing of subsequent arguments failed.
4066
Vinay Sajip35e3b032008-09-01 14:33:59 +00004067- Issue #2534: speed up isinstance() and issubclass() by 50-70%, so as to
Antoine Pitrou0668c622008-08-26 22:42:08 +00004068 match Python 2.5 speed despite the __instancecheck__ / __subclasscheck__
4069 mechanism. In the process, fix a bug where isinstance() and issubclass(),
4070 when given a tuple of classes as second argument, were looking up
4071 __instancecheck__ / __subclasscheck__ on the tuple rather than on each
4072 type object.
4073
Neal Norwitz18aa3882008-08-24 05:04:52 +00004074- Fix crashes on memory allocation failure found with failmalloc.

Brett Cannon1eaf0742008-09-02 01:25:16 +00004143 warnings.catch_warnings() along with some API cleanup. Expanding the tests
4144 for catch_warnings() also led to an improvement in the raising of a

4217-----------------
4218
Guido van Rossumf8402962008-08-20 15:01:50 +00004219- Issue #1878: Remove Py_TPFLAGS_HAVE_VERSION_TAG from
4220 Py_TPFLAGS_DEFAULT when not building the core. This means 3rd party
4221 extensions do not automatically benefit from the class attribute
4222 cache; they will have to explicitly add Py_TPFLAGS_HAVE_VERSION_TAG
4223 to their tp_flags field if they care. This is a backwards
4224 compatibility feature; in 3.0, all types will use the cache by
4225 default.
4226
Benjamin Petersonf647dc12008-08-20 01:27:30 +00004227- Keyword arguments can now follow starred arguments. (``f(a, *args,
4228 keyword=23)`` is now valid syntax.)
4229
Thomas Heller0ad5ae02008-08-19 19:25:04 +00004230- ctypes function pointers that are COM methods have a boolean True
4231 value again.

Martin v. Löwisf91d46a2008-08-12 14:49:50 +00004233- Issue #3139: Make buffer-interface thread-safe wrt. PyArg_ParseTuple,
4234 by denying s# to parse objects that have a releasebuffer procedure,
4235 and introducing s*.

Georg Brandl1e13ea92008-08-11 09:07:59 +00004237- Issue #3537: Fix an assertion failure when an empty but presized dict
4238 object was stored in the freelist.
4239
Mark Dickinsonb6467572008-08-04 21:30:09 +00004240- Issue #1481296: Make long(float('nan')) and int(float('nan')) raise
4241 ValueError consistently across platforms.
4242
Amaury Forgeot d'Arc39fd6722008-07-31 21:28:03 +00004243- Issue #3479: On platforms where sizeof(int) is smaller than sizeof(long)
4244 (64bit Unix, for example), unichr() would truncate its argument and return
4245 u'\x00' for unichr(2**32). Now it properly raises an OverflowError.
4246
Neal Norwitze7d8be82008-07-31 17:17:14 +00004247- Apply security patches from Apple.
4248
Amaury Forgeot d'Arc246daed2008-07-31 00:42:16 +00004249- Issue #2542: Now that issubclass() may call arbitrary code, ensure that

4251
Antoine Pitrou92f82162008-07-25 22:22:08 +00004252- Issue #1819: function calls with several named parameters are now on
4253 average 35% faster (as measured by pybench).
4254
Amaury Forgeot d'Arce4921fe2008-07-21 22:00:38 +00004255- Issue #2378: An unexpected UnboundLocalError or NameError could appear when
4256 the python debugger steps into a class statement: the free variables (local

Gregory P. Smith0470bab2008-07-22 04:46:32 +00004259- Issue #2620: Overflow checking when allocating or reallocating memory
4260 was not always being done properly in some python types and extension
4261 modules. PyMem_MALLOC, PyMem_REALLOC, PyMem_NEW and PyMem_RESIZE have
4262 all been updated to perform better checks and places in the code that
4263 would previously leak memory on the error path when such an allocation
4264 failed have been fixed.

Benjamin Petersone977ad42008-08-20 01:42:01 +00004271- The methods ``is_in_tuple()``, ``is_vararg()``, and ``is_keywordarg()`` of
4272 symtable.Symbol have been deprecated for removal in 3.0 and the next release.
4273
Amaury Forgeot d'Arc351ffb82008-08-18 19:23:47 +00004274- Issue #2234: distutils failed for some versions of the cygwin compiler. The
4275 version reported by these tools does not necessarily follow the python
4276 version numbering scheme, so the module is less strict when parsing it.
4277
Nick Coghlanf70385a2008-08-18 12:42:46 +00004278- Issue #2235: Added Py3k warnings for types which will become unhashable
4279 under the stricter __hash__ inheritance rules in 3.0. Several types
4280 which did not meet the rules for hash invariants and were already
4281 unhashable in 3.0 have now been explicitly flagged as unhashable in
4282 2.6 as well (collections.Mapping, collections.Set, unittest.TestSuite,
4283 xml.dom.minidom.NamedNodeMap, numbers.Number, UserList.UserList)
4284
Brett Cannon88f801d2008-08-18 00:46:22 +00004285- Update __all__ for cookielib, csv, os, urllib2, and weakref to include things

4317 since mimetools itself is deprecated. Because modules are cached, all
4318 subsequent imports of rfc822 will not raise a visible DeprecationWarning.

4329 a MemoryError rather than silently stop the iteration.
4330
Guido van Rossum59ce9012008-08-09 14:55:34 +00004331- Issue #3487: sre "bytecode" validator. Passing invalid "re-bytecode"
4332 to _sre.compile() will now be rejected. This should not affect anybody
4333 since the re.compile() function never generates invalid re-bytecode.
4334
Skip Montanaroa032bf42008-08-08 22:52:51 +00004335- Issue #3436: Make csv.DictReader's fieldnames attribute a property so that
4336 upon first access it can be automatically initialized from the csv file if
4337 it wasn't initialized during instantiation.
4338
Brett Cannon3aa2a492008-08-06 22:28:09 +00004339- Issue #2338: Create imp.reload() to help with transitioning to Python 3.0 as
4340 the reload() built-in has been removed.
4341
Brett Cannon7e30b672008-08-04 21:52:25 +00004342- Changed code in the following modules/packages to remove warnings raised
Brett Cannonc1b76e42008-08-09 23:06:16 +00004343 while running under the ``-3`` flag: aifc, asynchat, asyncore, bdb, bsddb,

Antoine Pitroude781a42008-08-09 12:43:23 +00004354 asking for a specific length. This problem only affected files opened
4355 using the new "io" module, not the built-in open() function.

4381 file name rather than a ZipInfo instance, so files are extracted with
4382 mode 0600 rather than 000 under Unix.
4383
Gregory P. Smitha36f8fe2008-08-04 00:13:29 +00004384- Issue #1857: subprocess.Popen.poll gained an additional _deadstate keyword
4385 argument in python 2.5, this broke code that subclassed Popen to include its

4397 interaction with the tp_hash slot (added in 2.6b2) are now documented
4398
Nick Coghlan2a0c2b12008-08-04 12:47:17 +00004399- Issue #643841: The language reference now provides more detailed
4400 coverage of the lookup process for special methods. The disclaimers
4401 regarding lack of coverage of new-style classes have also been
4402 removed, since the coverage is now fairly reasonable.

4406================================
4407
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00004408*Release date: 17-Jul-2008*

Raymond Hettingere3ae6552008-06-20 04:18:15 +00004410Core and Builtins
4411-----------------
4412
Georg Brandl3e483f62008-07-16 22:57:41 +00004413- Issue #3156: Fix inconsistent behavior of the bytearray type: all
4414 its methods now allow for items objects that can be converted to
4415 an integer using operator.index().
4416
Mark Dickinson64b7e502008-07-16 09:40:03 +00004417- Issue #3360: Fix incorrect parsing of '020000000000.0', which
4418 produced a ValueError instead of giving the correct float.
4419
Eric Smitha5fa5a22008-07-16 00:11:49 +00004420- Issue #3083: Add alternate (#) formatting for bin, oct, hex output
4421 for str.format(). This adds the prefix 0b, 0o, or 0x, respectively.
4422
Mark Dickinson7103aa42008-07-15 19:08:33 +00004423- Issue #3008: the float type has a new instance method 'float.hex'
4424 and a new class method 'float.fromhex' to convert floating-point
4425 numbers to and from hexadecimal strings, respectively.
4426
Nick Coghlan6d6bd442008-07-15 15:40:22 +00004427- Issue #2235: __hash__ is once again inherited by default. To allow
4428 collections.Hashable to remain meaningful in the presence of the
4429 default hash implementation (object.__hash__), it is now possible
4430 to explicit block inheritance of hash by setting __hash__=None at
4431 the Python level, or tp_hash=PyObject_HashNotImplemented at the C
4432 level.
4433
Nick Coghlanb028f502008-07-13 14:52:36 +00004434- Issue #3221: Issue a RuntimeWarning instead of raising SystemError if
4435 the parent module cannot be found while performing an absolute import.
4436 This means that an incorrectly defined __package__ attribute will
4437 now only prevent relative imports in that module rather than causing
4438 all imports from that module to fail.
4439
Nick Coghlan14ff9942008-07-08 14:21:42 +00004440- Issue #2517: Allow unicode messages in Exceptions again by correctly
4441 bypassing the instance dictionary when looking up __unicode__ on
4442 new-style classes.
4443
Amaury Forgeot d'Arcbdd941f2008-07-01 20:38:04 +00004444- Issue #3242: Fix a crash inside the print statement, if sys.stdout is
4445 set to a custom object whose write() method happens to install
4446 another file in sys.stdout.
4447
Amaury Forgeot d'Arc1f40c8a2008-06-30 22:42:40 +00004448- Issue #3088: Corrected a race condition in classes derived from
4449 threading.local: the first member set by a thread could be saved in
4450 another thread's dictionary.
4451
Mark Dickinson1ec2fcd2008-06-20 14:53:43 +00004452- Issue #3004: Minor change to slice.indices(): the start and stop
4453 arguments are now treated identically, making the behaviour easier
4454 to describe and understand. For example, slice(None, -10,
4455 1).indices(9) now returns (0, 0, 1) instead of (0, -1, 1), and
4456 slice(None, 10, -1).indices(10) returns (9, 9, -1) instead of (9,
4457 10, -1).
4458
Georg Brandl278fc502008-07-19 12:46:12 +00004459- Issue #3219: Calling a function with repeated keyword arguments,
4460 f(a=2, a=23), would not cause a syntax error. This was a regression
4461 from 2.4 caused by the switch to the new compiler.
Benjamin Peterson175e4d92008-07-01 19:34:52 +00004462
Georg Brandl278fc502008-07-19 12:46:12 +00004463- Issue #2862: Make int and float freelist management consistent with
4464 other freelists. Changes their CompactFreeList apis into
4465 ClearFreeList apis and calls them via gc.collect().

Thomas Heller57adf222008-08-14 19:10:48 +00004470- Issue #3554: ctypes.string_at and ctypes.wstring_at did call Python
4471 api functions without holding the GIL, which could lead to a fatal
4472 error when they failed.
4473
Martin v. Löwisaabf4042008-08-02 07:20:25 +00004474- Issue #799428: Fix Tkinter.Misc._nametowidget to unwrap Tcl command objects.

Jesse Noller13e9d582008-07-16 14:32:36 +00004482- Issue #3125: Remove copy_reg in multiprocessing and replace it with
4483 ForkingPickler.register() to resolve conflict with ctypes.
4484
Vinay Sajip51e65192008-07-18 09:01:10 +00004485- Issue #3090: Fixed ARCHFLAGS parsing on OS/X

Thomas Heller880f5292008-07-15 19:39:38 +00004487- Issue #3313: Fixed a crash when a failed dlopen() call does not set
4488 a valid dlerror() message.
4489
Thomas Heller2bad6572008-07-15 17:19:50 +00004490- Issue #3258: Fixed a crash when a ctypes POINTER type to an
4491 incomplete structure was created.
4492

Andrew M. Kuchlingcc3f2b12008-07-10 14:43:31 +00004497- Issue #3301: Bisect module behaved badly when lo was negative.
Raymond Hettinger3cd1e422008-07-10 14:03:19 +00004498
Amaury Forgeot d'Arc0f7cddc2008-07-06 21:34:39 +00004499- Issue #839496: SimpleHTTPServer used to open text files in text mode. This is
4500 both unnecessary (HTTP allows text content to be sent in several forms) and
Andrew M. Kuchlingcc3f2b12008-07-10 14:43:31 +00004501 wrong because the actual transmitted size could differ from the
Amaury Forgeot d'Arc0f7cddc2008-07-06 21:34:39 +00004502 content-length. The problem had been corrected in the 2.4 branch, but never
4503 merged into trunk.
4504
Georg Brandle78fbcc2008-07-05 10:13:36 +00004505- Issue #2663: add filtering capability to shutil.copytree().

Andrew M. Kuchlingcc3f2b12008-07-10 14:43:31 +00004516 when completed.
Facundo Batista66c52772008-07-02 16:52:55 +00004517
Nick Coghlanc060b0e2008-07-02 13:09:19 +00004518- Issue #3190: Pydoc now hides the automatic module attribute __package__ (the
4519 handling is now the same as that of other special attributes like __name__).
4520
Brett Cannon8bb8fa52008-07-02 01:57:08 +00004521- Issue #2885 (partial): The urllib.urlopen() function has been deprecated for
4522 removal in Python 3.0 in favor of urllib2.urlopen().

Georg Brandl5cc774e2008-06-11 20:28:06 +00004911 PPC64 and x86_64 support in one binary).
Ronald Oussoren5640ce22008-06-05 12:58:24 +00004912
4913 This is controlled by the configure argument ``--with-universal-archs``:
4914
4915 - ``--with-universal-archs=all``: install 4-way universal
4916
4917 - ``--with-universal-archs=32-bit``: install 2-way universal, 32-bit (the default)
4918
4919 - ``--with-universal-archs=64-bit``: install 2-way universal, 64-bit
4920
4921 This option should be used in combination with ``--enable-universalsdk=``.
4922
4923 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 +00004973- Issue #1631171: Re-implement the 'warnings' module in C (the
4974 original Python code has been kept as backup). This will allow for
4975 using the 'warning's machinery in such places as the parser where
4976 use of pure Python code is not possible. Both the ``showarning()``
4977 and ``formatwarning()`` gain an optional 'line' argument which is
4978 not called by default for backwards-compatibility reasons. Setting
4979 ``warnings.showwarning()`` to an implementation that lacks support
4980 for the ``line`` argument will raise a DeprecationWarning.

Georg Brandl3ee81df2008-05-17 18:14:43 +00005043- Issue #2550: The approach used by client/server code for obtaining
5044 ports to listen on in network-oriented tests has been refined in an
5045 effort to facilitate running multiple instances of the entire
5046 regression test suite in parallel without issue.
5047 test_support.bind_port() has been fixed such that it will always
5048 return a unique port -- which wasn't always the case with the
5049 previous implementation, especially if socket options had been set
5050 that affected address reuse (i.e. SO_REUSEADDR, SO_REUSEPORT). The
5051 new implementation of bind_port() will actually raise an exception
5052 if it is passed an AF_INET/SOCK_STREAM socket with either the
5053 SO_REUSEADDR or SO_REUSEPORT socket option set. Furthermore, if
5054 available, bind_port() will set the SO_EXCLUSIVEADDRUSE option on
5055 the socket it's been passed. This currently only applies to
5056 Windows. This option prevents any other sockets from binding to the
5057 host/port we've bound to, thus removing the possibility of the
5058 'non-deterministic' behaviour, as Microsoft puts it, that occurs
5059 when a second SOCK_STREAM socket binds and accepts to a host/port
5060 that's already been bound by another socket. The optional preferred
5061 port parameter to bind_port() has been removed. Under no
5062 circumstances should tests be hard coding ports!
5063
5064 test_support.find_unused_port() has also been introduced, which will
5065 pass a temporary socket object to bind_port() in order to obtain an
5066 unused port. The temporary socket object is then closed and
5067 deleted, and the port is returned. This method should only be used
5068 for obtaining an unused port in order to pass to an external program
5069 (i.e. the -accept [port] argument to openssl's s_server mode) or as
5070 a parameter to a server-oriented class that doesn't give you direct
5071 access to the underlying socket used.
5072
5073 Finally, test_support.HOST has been introduced, which should be used
5074 for the host argument of any relevant socket calls (i.e. bind and
5075 connect).
Trent Nelsone41b0062008-04-08 23:47:30 +00005076
5077 The following tests were updated to following the new conventions:
Georg Brandl3ee81df2008-05-17 18:14:43 +00005078 test_socket, test_smtplib, test_asyncore, test_ssl, test_httplib,
Trent Nelsone41b0062008-04-08 23:47:30 +00005079 test_poplib, test_ftplib, test_telnetlib, test_socketserver,
5080 test_asynchat and test_socket_ssl.
5081
Georg Brandl3ee81df2008-05-17 18:14:43 +00005082 It is now possible for multiple instances of the regression test
5083 suite to run in parallel without issue.

Fred Drakea8ee94b2008-03-01 02:45:07 +00005352- Issue #2051: pyc and pyo files are no longer created with permission
Barry Warsaw52973612008-03-01 02:23:38 +00005353 644. The mode is now inherited from the py file.
Christian Heimes40346852008-02-23 17:52:07 +00005354
Georg Brandlad61bc82008-02-23 15:11:18 +00005355- Issue #2067: file.__exit__() now calls subclasses' close() method.
5356
5357- Patch #1759: Backport of PEP 3129 class decorators.
Christian Heimes5224d282008-02-23 15:01:05 +00005358
Vinay Sajipb7edfc42008-04-02 21:10:23 +00005359- Issue #1881: An internal parser limit has been increased. Also see
Georg Brandl222e2082010-08-01 22:27:39 +00005360 issue #215555 for a discussion.
Facundo Batistafc2d0102008-02-23 12:01:13 +00005361
Eric Smitha73fbe72008-02-23 03:09:44 +00005362- Added the future_builtins module, which contains hex() and oct().
5363 These are the PEP 3127 version of these functions, designed to be
5364 compatible with the hex() and oct() builtins from Python 3.0. They
5365 differ slightly in their output formats from the existing, unchanged
5366 Python 2.6 builtins. The expected usage of the future_builtins
5367 module is:
5368 from future_builtins import hex, oct
5369
Eric Smith7ef40bf2008-02-20 23:34:22 +00005370- Issue #1600: Modifed PyOS_ascii_formatd to use at most 2 digit
5371 exponents for exponents with absolute value < 100. Follows C99
5372 standard. This is a change on Windows, which would use 3 digits.
5373 Also, added 'n' to the formats that PyOS_ascii_formatd understands,
5374 so that any alterations it does to the resulting string will be
5375 available in stringlib/formatter.h (for float.__format__).
5376
Eric Smith5a3c1352008-02-19 13:21:56 +00005377- Implemented PEP 3101, Advanced String Formatting. This adds a new
5378 builtin format(); a format() method for str and unicode; a
5379 __format__() method to object, str, unicode, int, long, float, and
5380 datetime; the class string.Formatter; and the C API
5381 PyObject_Format().
5382
Georg Brandl3ee81df2008-05-17 18:14:43 +00005383- Fixed several potential crashes, all caused by specially crafted
5384 __del__ methods exploiting objects in temporarily inconsistent
5385 state.
Amaury Forgeot d'Arc632fad32008-02-16 20:55:24 +00005386
Vinay Sajipb7edfc42008-04-02 21:10:23 +00005387- Issue #2115: Important speedup in setting __slot__ attributes. Also
Georg Brandl3ee81df2008-05-17 18:14:43 +00005388 prevent a possible crash: an Abstract Base Class would try to access
5389 a slot on a registered virtual subclass.
Amaury Forgeot d'Arc60d6c7f2008-02-15 21:22:45 +00005390
Georg Brandl3ee81df2008-05-17 18:14:43 +00005391- Fixed repr() and str() of complex numbers with infinity or nan as
5392 real or imaginary part.
Christian Heimes2f0da532008-02-15 06:57:08 +00005393
Georg Brandl3ee81df2008-05-17 18:14:43 +00005394- Clear all free lists during a gc.collect() of the highest generation
5395 in order to allow pymalloc to free more arenas. Python may give back
5396 memory to the OS earlier.
Christian Heimes3b718a72008-02-14 12:47:33 +00005397
Georg Brandl3ee81df2008-05-17 18:14:43 +00005398- Issue #2045: Fix an infinite recursion triggered when printing a
5399 subclass of collections.defaultdict, if its default_factory is set
5400 to a bound method.
Amaury Forgeot d'Arcb01aa432008-02-08 00:56:02 +00005401
Christian Heimesf75dbef2008-02-08 00:11:31 +00005402- Fixed a minor memory leak in dictobject.c. The content of the free
5403 list was not freed on interpreter shutdown.
5404
Georg Brandl21e99f42010-03-07 15:23:59 +00005405- Limit free list of method and built-in function objects to 256
Georg Brandl3ee81df2008-05-17 18:14:43 +00005406 entries each.
Christian Heimes6075a822008-02-06 12:44:34 +00005407
Georg Brandl3ee81df2008-05-17 18:14:43 +00005408- Patch #1953: Added ``sys._compact_freelists()`` and the C API
5409 functions ``PyInt_CompactFreeList`` and ``PyFloat_CompactFreeList``
Christian Heimes422051a2008-02-04 18:00:12 +00005410 to compact the internal free lists of pre-allocted ints and floats.
5411
Georg Brandl3ee81df2008-05-17 18:14:43 +00005412- Issue #1983: Fixed return type of fork(), fork1() and forkpty()
5413 calls. Python expected the return type int but the fork familie
5414 returns pi_t.
Christian Heimes951cc0f2008-01-31 23:08:23 +00005415
Georg Brandl3ee81df2008-05-17 18:14:43 +00005416- Issue #1678380: Fix a bug that identifies 0j and -0j when they
5417 appear in the same code unit.
Mark Dickinson105be772008-01-31 22:17:37 +00005418
Georg Brandl3ee81df2008-05-17 18:14:43 +00005419- Issue #2025: Add tuple.count() and tuple.index() methods to comply
5420 with the collections.Sequence API.
Raymond Hettinger5b07ebc2008-02-07 00:54:20 +00005421
Georg Brandl3ee81df2008-05-17 18:14:43 +00005422- Patch #1970 by Antoine Pitrou: Speedup unicode whitespace and
5423 linebreak detection
Christian Heimes4d4f2702008-01-30 11:32:37 +00005424
Georg Brandl3ee81df2008-05-17 18:14:43 +00005425- Added ``PyType_ClearCache()`` and ``sys._clear_type_cache`` to clear
5426 the internal lookup cache for ref leak tests.
Christian Heimes908caac2008-01-27 23:34:59 +00005427
Georg Brandl3ee81df2008-05-17 18:14:43 +00005428- Patch #1473257: generator objects gain a gi_code attribute. This is
5429 the same object as the func_code attribute of the function that
5430 produced the generator.
Georg Brandl0cdf9a32008-01-26 14:14:20 +00005431
Georg Brandl3ee81df2008-05-17 18:14:43 +00005432- Issue #1920: "while 0" statements were completely removed by the
5433 compiler, even in the presence of an "else" clause, which is
5434 supposed to be run when the condition is false. Now the compiler
5435 correctly emits bytecode for the "else" suite.
Amaury Forgeot d'Arc31eaafe2008-01-24 22:59:25 +00005436
Guido van Rossumeead05f2008-01-24 18:21:02 +00005437- A few crashers fixed: weakref_in_del.py (issue #1377858);
5438 loosing_dict_ref.py (issue #1303614, test67.py);
5439 borrowed_ref_[34].py (not in tracker).
5440
Vinay Sajipd7cf32e2008-01-24 12:43:33 +00005441- Issue #1069410: The "can't load dll" message box on Windows is
Christian Heimesb2302ba2008-01-23 17:15:06 +00005442 suppressed while an extension is loaded by calling SetErrorMode in
5443 dynload_win.c. The error is still reported properly.
5444
Georg Brandl3ee81df2008-05-17 18:14:43 +00005445- Issue #1915: Python compiles with --enable-unicode=no again. However
Christian Heimes082c9b02008-01-23 14:20:50 +00005446 several extension methods and modules do not work without unicode
5447 support.
5448
Georg Brandl26543b12008-01-21 18:36:51 +00005449- Issue #1882: when compiling code from a string, encoding cookies in the
5450 second line of code were not always recognized correctly.
5451
Georg Brandl14404b62008-01-19 19:27:05 +00005452- Issue #1679: "0x" was taken as a valid integer literal.
5453
Georg Brandl6caad7d2008-01-26 14:19:22 +00005454- Issue #1865: ``bytes`` as an alias for ``str`` and b"" as an alias "" were
Christian Heimes288e89a2008-01-18 18:24:07 +00005455 added.
5456
Christian Heimesc94e2b52008-01-14 04:13:37 +00005457- sys.float_info / PyFloat_GetInfo: The floating point information
5458 object was converted from a dict to a specialized structseq object.
5459
Georg Brandl3ee81df2008-05-17 18:14:43 +00005460- Patch #1816: Added sys.flags structseq. It exposes the status of
5461 most command line arguments and PYTHON* environment variables.
Christian Heimesf31b69f2008-01-14 03:42:48 +00005462
Georg Brandl3ee81df2008-05-17 18:14:43 +00005463- Objects/structseq.c: Implemented new structseq representation. The
5464 patch makes structseqs (e.g. the return value of os.stat) more
5465 readable.
Christian Heimes9c201962008-01-14 03:33:52 +00005466
Georg Brandl3ee81df2008-05-17 18:14:43 +00005467- Patch #1700288: added a type attribute cache that caches method
5468 accesses, resulting in speedups in heavily object-oriented code.
Amaury Forgeot d'Arce4c270c2008-01-14 00:29:41 +00005469
Neal Norwitz3fc15b82008-01-10 05:42:58 +00005470- Bug #1776: __import__() no longer accepts filenames on any platform.
5471 The first parameter to __import__() must be a valid module name.
Christian Heimes3403f152008-01-09 19:56:33 +00005472

5474
Georg Brandl3ee81df2008-05-17 18:14:43 +00005475- Patch #602345: Add -B command line option, PYTHONDONTWRITEBYTECODE
5476 envvar and sys.dont_write_bytecode attribute. All these can be set
5477 to forbid Python to attempt to write compiled bytecode files.
Georg Brandl2da0fce2008-01-07 17:09:35 +00005478
Georg Brandl3ee81df2008-05-17 18:14:43 +00005479- Improve some exception messages when Windows fails to load an
5480 extension module. Now we get for example '%1 is not a valid Win32
5481 application' instead of 'error code 193'.
Amaury Forgeot d'Arce0b76952008-01-04 02:04:15 +00005482
Georg Brandl3ee81df2008-05-17 18:14:43 +00005483- Bug #1481296: Fixed long(float('nan')) != 0L.

Georg Brandl3ee81df2008-05-17 18:14:43 +00005485- Issue #1640: Added math.isinf(x), math.isnan(x) and math.copysign(x,
5486 y) functions.
Christian Heimese2ca4242008-01-03 20:23:15 +00005487
Christian Heimes0a8143f2007-12-18 23:22:54 +00005488- Issue #1635: Platform independent creation and representation of NaN
Georg Brandl3ee81df2008-05-17 18:14:43 +00005489 and INF. float("nan"), float("inf") and float("-inf") now work on
5490 every platform with IEEE 754 semantics.
Christian Heimes0a8143f2007-12-18 23:22:54 +00005491
Georg Brandl3ee81df2008-05-17 18:14:43 +00005492- Compiler now generates simpler and faster code for dictionary
5493 literals. The oparg for BUILD_MAP now indicates an estimated
5494 dictionary size. There is a new opcode, STORE_MAP, for adding
5495 entries to the dictionary.
Raymond Hettingerfd7ed402007-12-18 21:24:09 +00005496
Georg Brandl3ee81df2008-05-17 18:14:43 +00005497- Issue #1638: %zd configure test fails on Linux.

5525 file can now be directly executed by passing their name to the
5526 interpreter. The directory/zipfile is automatically inserted as the
5527 first entry in sys.path.
Nick Coghlan327a39b2007-11-18 11:56:28 +00005528
Georg Brandl3ee81df2008-05-17 18:14:43 +00005529- Issue #1265: Fix a problem with sys.settrace, if the tracing
5530 function uses a generator expression when at the same time the
5531 executed code is closing a paused generator.
Amaury Forgeot d'Arc0d75f092007-11-13 21:54:28 +00005532
Raymond Hettinger1760c8a2007-11-08 02:52:43 +00005533- sets and frozensets now have an isdisjoint() method.
5534
Raymond Hettinger3f8caa32007-10-24 01:28:33 +00005535- optimize the performance of builtin.sum().

Neal Norwitz44f326e2007-10-05 05:29:17 +00005537- Fix warnings found by the new version of the Coverity checker.
5538
Georg Brandl21e99f42010-03-07 15:23:59 +00005539- The enumerate() built-in function is no longer bounded to sequences
Georg Brandl3ee81df2008-05-17 18:14:43 +00005540 smaller than LONG_MAX. Formerly, it raised an OverflowError. Now,
5541 automatically shifts from ints to longs.
Raymond Hettinger8f669372007-10-03 21:18:11 +00005542
Georg Brandl3ee81df2008-05-17 18:14:43 +00005543- Issue #1686386: Tuple's tp_repr did not take into account the
5544 possibility of having a self-referential tuple, which is possible
5545 from C code. Nor did object's tp_str consider that a type's tp_str
5546 could do something that could lead to an inifinite recursion.
5547 Py_ReprEnter() and Py_EnterRecursiveCall(), respectively, fixed the
5548 issues.
Brett Cannon0b14f242007-09-30 19:45:10 +00005549
Georg Brandl3ee81df2008-05-17 18:14:43 +00005550- Issue #1164: It was possible to trigger deadlock when using the
5551 'print' statement to write to a file since the GIL was not released
5552 as needed. Now PyObject_Print() does the right thing along with
5553 various tp_print implementations of the built-in types and those in
5554 the collections module.
Brett Cannon01531592007-09-17 03:28:34 +00005555
Georg Brandl3ee81df2008-05-17 18:14:43 +00005556- Issue #1147: Exceptions were directly allowing string exceptions in
5557 their throw() method even though string exceptions no longer
5558 allowed.
Brett Cannon4c20bc42007-09-11 21:02:28 +00005559

Brett Cannon1e534b52007-09-07 04:18:30 +00005563- Issue #1202533: Fix infinite recursion calls triggered by calls to
Georg Brandl3ee81df2008-05-17 18:14:43 +00005564 PyObject_Call() never calling back out to Python code to trigger
5565 recursion depth updates/checks. Required the creation of a static
5566 RuntimeError instance in case normalizing an exception put the
5567 recursion check value past its limit. Fixes crashers
5568 infinite_rec_(1|2|4|5).py.
Brett Cannon1e534b52007-09-07 04:18:30 +00005569

Neal Norwitz0ac60192007-05-27 04:08:54 +00005583- Add new attribute names for function objects. All the func_* become
Georg Brandl3ee81df2008-05-17 18:14:43 +00005584 __*__ attributes. (Some already existed, e.g., __doc__ and
5585 __name__.)
Neal Norwitz0ac60192007-05-27 04:08:54 +00005586
Neal Norwitz8b2bfbc2007-05-23 06:35:32 +00005587- Add -3 option to the interpreter to warn about features that are
5588 deprecated and will be changed/removed in Python 3.0.
5589
Georg Brandl2134e752007-05-21 20:34:16 +00005590- Patch #1686487: you can now pass any mapping after '**' in function
5591 calls.

5595 with Python 3.0.

Guido van Rossum143b5642007-03-23 04:58:42 +00005616- Bug #1683368: The object.__init__() and object.__new__() methods are
5617 now stricter in rejecting excess arguments. The only time when
5618 either allows excess arguments is when it is not overridden and the
5619 other one is. For backwards compatibility, when both are
5620 overridden, it is a deprecation warning (for now; maybe a Py3k
Guido van Rossum234b1ff2007-03-23 19:39:01 +00005621 warning later). Also, type.__init__() insists on the same signature
5622 as supported by type.__new__().

Georg Brandl3ee81df2008-05-17 18:14:43 +00005624- Patch #1675423: PyComplex_AsCComplex() now tries to convert an

5626 to the __float__() method. Therefore, the functions in the cmath
5627 module now can operate on objects that define a __complex__()
5628 method.

5648
Georg Brandl871f1bc2007-03-12 13:17:36 +00005649- The dir() function has been extended to call the __dir__() method on

5651 allows customizing the output of dir() in the presence of a

5662 raising a ValueError.

Georg Brandlaa2321b2007-03-07 00:40:28 +00005664- Patch #703779: unset __file__ in __main__ after running a file. This
Georg Brandl3ee81df2008-05-17 18:14:43 +00005665 makes the filenames the warning module prints much more sensible
5666 when a PYTHONSTARTUP file is used.

6309 TestCase and TestSuite subclasses (not instances) are no longer

Georg Brandl3ee81df2008-05-17 18:14:43 +00006594- Issue #829951: In the smtplib module, SMTP.starttls() now complies
6595 with RFC 3207 and forgets any knowledge obtained from the server not
6596 obtained from the TLS negotiation itself. Patch contributed by Bill
6597 Fenner.
Gregory P. Smith2b3ba582008-01-17 08:03:17 +00006598
Georg Brandl3ee81df2008-05-17 18:14:43 +00006599- Issue #1339: The smtplib.SMTP class has been refactored a bit such
Gregory P. Smithbde4ae42008-01-17 08:35:49 +00006600 that the SMTP.starttls() caller no longer needs to call ehlo()
6601 beforehand. SMTP.starttls() now raises an exception of the server
Georg Brandl3ee81df2008-05-17 18:14:43 +00006602 does not claim to support starttls. Adds the
6603 SMTP.ehlo_or_helo_if_needed() method. Patch contributed by Bill

6684 complex, tuple, list, dict, set, and frozenset. Formerly, it would
6685 silently miscode subclasses of those types. Now, it raises a
6686 ValueError instead.
Raymond Hettinger12e94202007-11-07 01:13:09 +00006687

Georg Brandl3ee81df2008-05-17 18:14:43 +00006702 time so that opening a database previously created with the DB_DUP
6703 or DB_DUPSORT flag set will keep the proper behavior on subsequent
6704 opens. Specifically: dictionary assignment to a DB object will
6705 replace all values for a given key when the database allows
6706 duplicate values. DB users should use DB.put(k, v) when they want
6707 to store duplicates; not DB[k] = v.
Gregory P. Smithec10a4a2007-11-05 02:32:26 +00006708

6714 characters with ASCII value less than 32. Also, it correctly quotes
6715 dots only if they occur on a single line, as opposed to the previous
6716 behavior of quoting dots if they are the second character of any
6717 line.
Georg Brandl4aef7272007-03-13 22:49:43 +00006718

7061
Georg Brandl3ee81df2008-05-17 18:14:43 +00007062- Issue #1521: On 64bit platforms, using PyArgs_ParseTuple with the t#
7063 of w# format code incorrectly truncated the length to an int, even
7064 when PY_SSIZE_T_CLEAN is set. The str.decode method used to return
7065 incorrect results with huge strings.

Georg Brandl3ee81df2008-05-17 18:14:43 +00007067- Issue #1629: Renamed Py_Size, Py_Type and Py_Refcnt to Py_SIZE,
7068 Py_TYPE and Py_REFCNT.

7084
7085- Fix some leftovers from the conversion from int to Py_ssize_t
7086 (relevant to strings and sequences of more than 2**31 items).
7087
7088- Make _PyGILState_NoteThreadState() static, it was not used anywhere
7089 outside of pystate.c and should not be necessary.

Georg Brandl3ee81df2008-05-17 18:14:43 +00007095- Added case insensitive comparison methods ``PyOS_stricmp(char*,
7096 char*)`` and ``PyOS_strnicmp(char*, char*, Py_ssize_t)``.
Christian Heimes000a0742008-01-03 22:16:32 +00007097
Georg Brandl3ee81df2008-05-17 18:14:43 +00007098- Bug #1542693: remove semi-colon at end of PyImport_ImportModuleEx

Georg Brandl3ee81df2008-05-17 18:14:43 +00007105- Patch #1706: Drop support for Win9x, WinME and NT4. Python now
7106 requires Windows 2000 or greater. The _WINVER and NTDDI_VERSION
7107 macros are set to Win2k for x86/32bit builds and WinXP for AMD64
7108 builds.

Georg Brandl3ee81df2008-05-17 18:14:43 +00007123- Removed the macfs module. It had been deprecated since Python 2.5.
7124 This lead to the deprecation of macostools.touched() as it relied
7125 solely on macfs and was a no-op under OS X.
