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

Ezio Melottiab2eb0e2010-06-05 19:21:32 +00001032- Issue #8271: during the decoding of an invalid UTF-8 byte sequence, only the
1033 start byte and the continuation byte(s) are now considered invalid, instead
1034 of the number of bytes specified by the start byte.
1035 E.g.: '\xf1\x80AB'.decode('utf-8', 'replace') now returns u'\ufffdAB' and
1036 replaces with U+FFFD only the start byte ('\xf1') and the continuation byte
1037 ('\x80') even if '\xf1' is the start byte of a 4-bytes sequence.

Mark Dickinson4ca7c3c2010-05-30 13:18:10 +00001046- Issue #8748: Fix two issues with comparisons between complex and integer
1047 objects. (1) The comparison could incorrectly return True in some cases
1048 (2**53+1 == complex(2**53) == 2**53), breaking transivity of equality.
1049 (2) The comparison raised an OverflowError for large integers, leading

Georg Brandlfee0f442010-05-22 21:26:21 +00001433- Issue #7994: Issue a PendingDeprecationWarning if object.__format__ is called
1434 with a non-empty format string. This is an effort to future-proof user
1435 code. If a derived class does not currently implement __format__ but later
1436 adds its own __format__, it would most likely break user code that had
Antoine Pitrou01a196a2011-01-02 20:05:11 +00001437 supplied a format string. This will be changed to a DeprecationWarning in
Georg Brandlfee0f442010-05-22 21:26:21 +00001438 Python 3.3 and it will be an error in Python 3.4.

Mark Dickinson8efef5c2010-01-12 22:23:56 +00001886
Georg Brandlba83f822010-03-14 09:50:54 +00001887 (1) a serious 'wrong output' bug that could occur for long (> 40 digit) input
1888 strings,
1889 (2) a crash in dtoa.c that occurred in debug builds when parsing certain long
1890 numeric strings corresponding to subnormal values,
1891 (3) a memory leak for some values large enough to cause overflow, and
1892 (4) a number of flaws that could lead to incorrectly rounded results.

Georg Brandlba83f822010-03-14 09:50:54 +00001931 file position when calling `truncate()`. It would previously change the file
1932 position to the given argument, which goes against the tradition of
Antoine Pitrouf3fa0742010-01-31 22:26:04 +00001933 ftruncate() and other truncation APIs. Patch by Pascal Chambon.

1936 class used to represent files stored inside an archive. The new
1937 implementation is significantly faster and can be wrapped in a
1938 ``io.BufferedReader`` object for more speedups. It also solves an issue
1939 where interleaved calls to ``read()`` and ``readline()`` give wrong results.

Georg Brandlba83f822010-03-14 09:50:54 +00001950- Issue #7748: Since unicode values are supported for some metadata options in
1951 Distutils, the DistributionMetadata get_* methods will now return an utf-8
1952 encoded string for them. This ensures that the upload and register commands
1953 send the correct values to PyPI without any error.

2027Core and Builtins
2028-----------------
2029
Georg Brandlba83f822010-03-14 09:50:54 +00002030- The ``__complex__()`` method is now looked up on the class of instances to
2031 make it consistent with other special methods.

Antoine Pitrou5b7139a2010-01-02 21:12:58 +00002033- Issue #7462: Implement the stringlib fast search algorithm for the `rfind`,
2034 `rindex`, `rsplit` and `rpartition` methods. Patch by Florent Xicluna.
2035
Mark Dickinson1b34d252010-01-01 17:27:30 +00002036- Issue #5080: A number of functions and methods previously produced a
Georg Brandlba83f822010-03-14 09:50:54 +00002037 DeprecationWarning when passed a float argument where an integer was expected.
2038 These functions and methods now raise TypeError instead. The majority of the
2039 effects of this change are in the extension modules, but some core functions
2040 and methods are affected: notably the 'chr', 'range' and 'xrange' builtins,
2041 and many unicode/str methods.

2055 of integers: the result of a/b is now correctly rounded for ints a and b (at
2056 least on IEEE 754 platforms), and in particular does not depend on the
2057 internal representation of a long.

2065
Georg Brandlba83f822010-03-14 09:50:54 +00002066 These executables now work properly with the arch(1) command: ``arch -ppc
2067 python`` will start a universal binary version of python in PPC mode (unlike

Georg Brandlba83f822010-03-14 09:50:54 +00002224- Issue #7117: ``repr(x)`` for a float x returns a result based on the shortest
2225 decimal string that's guaranteed to round back to x under correct rounding
2226 (with round-half-to-even rounding mode). Previously it gave a string based on
2227 rounding x to 17 decimal digits. repr(x) for a complex number behaves
2228 similarly. On platforms where the correctly-rounded strtod and dtoa code is
2229 not supported (see below), repr is unchanged.
Mark Dickinsonb678de82009-11-19 18:41:49 +00002230
Georg Brandlba83f822010-03-14 09:50:54 +00002231- Issue #7117: On almost all platforms: float-to-string and string-to-float
2232 conversions within Python are now correctly rounded. Places these conversions
2233 occur include: str for floats and complex numbers; the float and complex
2234 constructors; old-style and new-style numeric formatting; serialization and
2235 deserialization of floats and complex numbers using marshal, pickle and json;
2236 parsing of float and imaginary literals in Python code; Decimal-to-float
2237 conversion.
Mark Dickinsonb678de82009-11-19 18:41:49 +00002238
Georg Brandlba83f822010-03-14 09:50:54 +00002239 The conversions use a Python-adapted version of David Gay's well-known dtoa.c,
2240 providing correctly-rounded strtod and dtoa C functions. This code is
2241 supported on Windows, and on Unix-like platforms using gcc, icc or suncc as
2242 the C compiler. There may be a small number of platforms on which correct
2243 operation of this code cannot be guaranteed, so the code is not used: notably,
2244 this applies to platforms where the C double format is not IEEE 754 binary64,
2245 and to platforms on x86 hardware where the x87 FPU is set to 64-bit precision
2246 and Python's configure script is unable to determine how to change the FPU
2247 precision. On these platforms conversions use the platform strtod and dtoa,
2248 as before.

Georg Brandlba83f822010-03-14 09:50:54 +00002250- Issue #7117: Backport round implementation from Python 3.x. ``round()`` now
2251 uses the correctly-rounded string <-> float conversions described above (when
2252 available), and so produces correctly rounded results that will display nicely
2253 under the float repr. There are two related small changes: (1) round now
2254 accepts any class with an ``__index__()`` method for its second argument (but
2255 no longer accepts floats for the second argument), and (2) an excessively
2256 large second integer argument (e.g., ``round(1.234, 10**100)``) no longer
2257 raises an exception.

Georg Brandlba83f822010-03-14 09:50:54 +00002404- Issue #5920: For ``float.__format__()``, change the behavior with the empty
2405 presentation type (that is, not one of 'e', 'f', 'g', or 'n') to be like 'g'
2406 but with at least one decimal point and with a default precision
2407 of 12. Previously, the behavior the same but with a default precision of 6.
2408 This more closely matches ``str()``, and reduces surprises when adding
2409 alignment flags to the empty presentation type. This also affects the new
2410 complex.__format__ in the same way.
2411

Georg Brandlba83f822010-03-14 09:50:54 +00002593- Issue #4445: Replace ``sizeof(PyStringObject)`` with
2594 ``offsetof(PyStringObject, ob_sval) + 1`` when allocating memory for str
2595 instances. On a typical machine this saves 3 bytes of memory (on average) per

Amaury Forgeot d'Arcdc619012008-11-22 20:01:18 +00002598- Issue #3996: On Windows, the PyOS_CheckStack function would cause the

2607
Georg Brandlba83f822010-03-14 09:50:54 +00002608- Issue #4233: Changed semantic of ``_fileio.FileIO``'s ``close()`` method on
2609 file objects with closefd=False. The file descriptor is still kept open but
2610 the file object behaves like a closed file. The ``FileIO`` object also got a
2611 new readonly attribute ``closefd``.

Georg Brandlba83f822010-03-14 09:50:54 +00002634- On windows, ``os.chdir()`` given unicode was not working if

2636 this code path is really executed because I cannot move to such directory on

Georg Brandlba83f822010-03-14 09:50:54 +00002639- Issue #4069: When ``set.remove(element)`` is used with a set element, the
2640 element is temporarily replaced with an equivalent frozenset. But the
2641 eventual KeyError would always report the empty ``frozenset()`` as the missing

Walter Dörwalded960ac2009-05-03 22:36:33 +00002662- Issue #5108: Handle %s like %S and %R in PyUnicode_FromFormatV(): Call
2663 PyUnicode_DecodeUTF8() once, remember the result and output it in a second
2664 step. This avoids problems with counting UTF-8 bytes that ignores the effect
2665 of using the replace error handler in PyUnicode_DecodeUTF8().
2666
Walter Dörwald726ba8e2009-05-06 14:32:35 +00002667- Issue #3739: The unicode-internal encoder now reports the number of characters

2669
Georg Brandlba83f822010-03-14 09:50:54 +00002670- Issue #2422: When compiled with the ``--with-valgrind`` option, the pymalloc
2671 allocator will be automatically disabled when running under Valgrind. This
2672 gives improved memory leak detection when running under Valgrind, while taking
2673 advantage of pymalloc at other times.

Martin v. Löwis9fa5a282008-09-11 06:53:30 +00004038- Issue #3642: Suppress warning in obmalloc when size_t is larger than uint.
4039
Amaury Forgeot d'Arc05e34492008-09-10 22:04:45 +00004040- Issue #3743: In a few places, PY_FORMAT_SIZE_T was incorrectly used with
4041 PyString_FromFormat or PyErr_Format to display size_t values. The macro
4042 PY_FORMAT_SIZE_T is designed to select the correct format for the OS
4043 ``printf`` function, whereas PyString_FromFormat has an independent
4044 implementation and uses "%zd" on all platforms for size_t values.
4045 This makes a difference on win64, where ``printf`` needs "%Id" to display
4046 64bit values.

Benjamin Peterson97179b02008-09-09 20:55:01 +00004048- Issue #3634: _weakref.ref(Exception).__init__() gave invalid return value on

4052 object; previously an int would be returned for small values. the __long__
4053 method is allowed to return either an int or a long, but the behaviour of
4054 float objects should not change to respect backward compatibility.

Amaury Forgeot d'Arc3571fbf2008-09-01 19:52:00 +00004056- Issue #3751: str.rpartition would perform a left-partition when called with

Vinay Sajip35e3b032008-09-01 14:33:59 +00004062 PyArg_ParseTuple and friends, which occurred when the argument for "s*"
Antoine Pitroud4ae97b2008-08-29 18:39:48 +00004063 was correctly parsed but parsing of subsequent arguments failed.
4064
Vinay Sajip35e3b032008-09-01 14:33:59 +00004065- Issue #2534: speed up isinstance() and issubclass() by 50-70%, so as to
Antoine Pitrou0668c622008-08-26 22:42:08 +00004066 match Python 2.5 speed despite the __instancecheck__ / __subclasscheck__
4067 mechanism. In the process, fix a bug where isinstance() and issubclass(),
4068 when given a tuple of classes as second argument, were looking up
4069 __instancecheck__ / __subclasscheck__ on the tuple rather than on each
4070 type object.

4215-----------------
4216
Guido van Rossumf8402962008-08-20 15:01:50 +00004217- Issue #1878: Remove Py_TPFLAGS_HAVE_VERSION_TAG from
4218 Py_TPFLAGS_DEFAULT when not building the core. This means 3rd party
4219 extensions do not automatically benefit from the class attribute
4220 cache; they will have to explicitly add Py_TPFLAGS_HAVE_VERSION_TAG
4221 to their tp_flags field if they care. This is a backwards
4222 compatibility feature; in 3.0, all types will use the cache by
4223 default.
4224
Benjamin Petersonf647dc12008-08-20 01:27:30 +00004225- Keyword arguments can now follow starred arguments. (``f(a, *args,
4226 keyword=23)`` is now valid syntax.)
4227
Thomas Heller0ad5ae02008-08-19 19:25:04 +00004228- ctypes function pointers that are COM methods have a boolean True
4229 value again.

Georg Brandl1e13ea92008-08-11 09:07:59 +00004235- Issue #3537: Fix an assertion failure when an empty but presized dict
4236 object was stored in the freelist.

Mark Dickinsonb6467572008-08-04 21:30:09 +00004238- Issue #1481296: Make long(float('nan')) and int(float('nan')) raise
4239 ValueError consistently across platforms.
4240
Amaury Forgeot d'Arc39fd6722008-07-31 21:28:03 +00004241- Issue #3479: On platforms where sizeof(int) is smaller than sizeof(long)
4242 (64bit Unix, for example), unichr() would truncate its argument and return
4243 u'\x00' for unichr(2**32). Now it properly raises an OverflowError.
4244
Neal Norwitze7d8be82008-07-31 17:17:14 +00004245- Apply security patches from Apple.
4246
Amaury Forgeot d'Arc246daed2008-07-31 00:42:16 +00004247- Issue #2542: Now that issubclass() may call arbitrary code, ensure that

4249
Antoine Pitrou92f82162008-07-25 22:22:08 +00004250- Issue #1819: function calls with several named parameters are now on
4251 average 35% faster (as measured by pybench).
4252
Amaury Forgeot d'Arce4921fe2008-07-21 22:00:38 +00004253- Issue #2378: An unexpected UnboundLocalError or NameError could appear when
4254 the python debugger steps into a class statement: the free variables (local

Gregory P. Smith0470bab2008-07-22 04:46:32 +00004257- Issue #2620: Overflow checking when allocating or reallocating memory
4258 was not always being done properly in some python types and extension
4259 modules. PyMem_MALLOC, PyMem_REALLOC, PyMem_NEW and PyMem_RESIZE have
4260 all been updated to perform better checks and places in the code that
4261 would previously leak memory on the error path when such an allocation
4262 failed have been fixed.

Benjamin Petersone977ad42008-08-20 01:42:01 +00004269- The methods ``is_in_tuple()``, ``is_vararg()``, and ``is_keywordarg()`` of
4270 symtable.Symbol have been deprecated for removal in 3.0 and the next release.
4271
Amaury Forgeot d'Arc351ffb82008-08-18 19:23:47 +00004272- Issue #2234: distutils failed for some versions of the cygwin compiler. The
4273 version reported by these tools does not necessarily follow the python
4274 version numbering scheme, so the module is less strict when parsing it.
4275
Nick Coghlanf70385a2008-08-18 12:42:46 +00004276- Issue #2235: Added Py3k warnings for types which will become unhashable
4277 under the stricter __hash__ inheritance rules in 3.0. Several types
4278 which did not meet the rules for hash invariants and were already
4279 unhashable in 3.0 have now been explicitly flagged as unhashable in
4280 2.6 as well (collections.Mapping, collections.Set, unittest.TestSuite,
4281 xml.dom.minidom.NamedNodeMap, numbers.Number, UserList.UserList)
4282
Brett Cannon88f801d2008-08-18 00:46:22 +00004283- Update __all__ for cookielib, csv, os, urllib2, and weakref to include things

4315 since mimetools itself is deprecated. Because modules are cached, all
4316 subsequent imports of rfc822 will not raise a visible DeprecationWarning.
4317

4327 a MemoryError rather than silently stop the iteration.
4328
Guido van Rossum59ce9012008-08-09 14:55:34 +00004329- Issue #3487: sre "bytecode" validator. Passing invalid "re-bytecode"
4330 to _sre.compile() will now be rejected. This should not affect anybody
4331 since the re.compile() function never generates invalid re-bytecode.
4332
Skip Montanaroa032bf42008-08-08 22:52:51 +00004333- Issue #3436: Make csv.DictReader's fieldnames attribute a property so that
4334 upon first access it can be automatically initialized from the csv file if
4335 it wasn't initialized during instantiation.
4336
Brett Cannon3aa2a492008-08-06 22:28:09 +00004337- Issue #2338: Create imp.reload() to help with transitioning to Python 3.0 as
4338 the reload() built-in has been removed.
4339
Brett Cannon7e30b672008-08-04 21:52:25 +00004340- Changed code in the following modules/packages to remove warnings raised
Brett Cannonc1b76e42008-08-09 23:06:16 +00004341 while running under the ``-3`` flag: aifc, asynchat, asyncore, bdb, bsddb,

Antoine Pitroude781a42008-08-09 12:43:23 +00004352 asking for a specific length. This problem only affected files opened
4353 using the new "io" module, not the built-in open() function.

Antoine Pitrou5fdfa3e2008-07-25 19:42:26 +00004378- Issue #3394: zipfile.writestr sets external attributes when passed a
4379 file name rather than a ZipInfo instance, so files are extracted with
4380 mode 0600 rather than 000 under Unix.
4381
Gregory P. Smitha36f8fe2008-08-04 00:13:29 +00004382- Issue #1857: subprocess.Popen.poll gained an additional _deadstate keyword
4383 argument in python 2.5, this broke code that subclassed Popen to include its

4395 interaction with the tp_hash slot (added in 2.6b2) are now documented
4396
Nick Coghlan2a0c2b12008-08-04 12:47:17 +00004397- Issue #643841: The language reference now provides more detailed
4398 coverage of the lookup process for special methods. The disclaimers
4399 regarding lack of coverage of new-style classes have also been
4400 removed, since the coverage is now fairly reasonable.

Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00004406*Release date: 17-Jul-2008*

Raymond Hettingere3ae6552008-06-20 04:18:15 +00004408Core and Builtins
4409-----------------
4410
Georg Brandl3e483f62008-07-16 22:57:41 +00004411- Issue #3156: Fix inconsistent behavior of the bytearray type: all
4412 its methods now allow for items objects that can be converted to
4413 an integer using operator.index().
4414
Mark Dickinson64b7e502008-07-16 09:40:03 +00004415- Issue #3360: Fix incorrect parsing of '020000000000.0', which
4416 produced a ValueError instead of giving the correct float.
4417
Eric Smitha5fa5a22008-07-16 00:11:49 +00004418- Issue #3083: Add alternate (#) formatting for bin, oct, hex output
4419 for str.format(). This adds the prefix 0b, 0o, or 0x, respectively.
4420
Mark Dickinson7103aa42008-07-15 19:08:33 +00004421- Issue #3008: the float type has a new instance method 'float.hex'
4422 and a new class method 'float.fromhex' to convert floating-point
4423 numbers to and from hexadecimal strings, respectively.
4424
Nick Coghlan6d6bd442008-07-15 15:40:22 +00004425- Issue #2235: __hash__ is once again inherited by default. To allow
4426 collections.Hashable to remain meaningful in the presence of the
4427 default hash implementation (object.__hash__), it is now possible
4428 to explicit block inheritance of hash by setting __hash__=None at
4429 the Python level, or tp_hash=PyObject_HashNotImplemented at the C
4430 level.
4431
Nick Coghlanb028f502008-07-13 14:52:36 +00004432- Issue #3221: Issue a RuntimeWarning instead of raising SystemError if
4433 the parent module cannot be found while performing an absolute import.
4434 This means that an incorrectly defined __package__ attribute will
4435 now only prevent relative imports in that module rather than causing
4436 all imports from that module to fail.
4437
Nick Coghlan14ff9942008-07-08 14:21:42 +00004438- Issue #2517: Allow unicode messages in Exceptions again by correctly
4439 bypassing the instance dictionary when looking up __unicode__ on
4440 new-style classes.
4441
Amaury Forgeot d'Arcbdd941f2008-07-01 20:38:04 +00004442- Issue #3242: Fix a crash inside the print statement, if sys.stdout is
4443 set to a custom object whose write() method happens to install
4444 another file in sys.stdout.
4445
Amaury Forgeot d'Arc1f40c8a2008-06-30 22:42:40 +00004446- Issue #3088: Corrected a race condition in classes derived from
4447 threading.local: the first member set by a thread could be saved in
4448 another thread's dictionary.
4449
Mark Dickinson1ec2fcd2008-06-20 14:53:43 +00004450- Issue #3004: Minor change to slice.indices(): the start and stop
4451 arguments are now treated identically, making the behaviour easier
4452 to describe and understand. For example, slice(None, -10,
4453 1).indices(9) now returns (0, 0, 1) instead of (0, -1, 1), and
4454 slice(None, 10, -1).indices(10) returns (9, 9, -1) instead of (9,
4455 10, -1).
4456
Georg Brandl278fc502008-07-19 12:46:12 +00004457- Issue #3219: Calling a function with repeated keyword arguments,
4458 f(a=2, a=23), would not cause a syntax error. This was a regression
4459 from 2.4 caused by the switch to the new compiler.
Benjamin Peterson175e4d92008-07-01 19:34:52 +00004460
Georg Brandl278fc502008-07-19 12:46:12 +00004461- Issue #2862: Make int and float freelist management consistent with
4462 other freelists. Changes their CompactFreeList apis into
4463 ClearFreeList apis and calls them via gc.collect().
Gregory P. Smith2fe77062008-07-06 03:35:58 +00004464

Thomas Heller57adf222008-08-14 19:10:48 +00004468- Issue #3554: ctypes.string_at and ctypes.wstring_at did call Python
4469 api functions without holding the GIL, which could lead to a fatal
4470 error when they failed.
4471
Martin v. Löwisaabf4042008-08-02 07:20:25 +00004472- Issue #799428: Fix Tkinter.Misc._nametowidget to unwrap Tcl command objects.

Jesse Noller13e9d582008-07-16 14:32:36 +00004480- Issue #3125: Remove copy_reg in multiprocessing and replace it with
4481 ForkingPickler.register() to resolve conflict with ctypes.
4482
Vinay Sajip51e65192008-07-18 09:01:10 +00004483- Issue #3090: Fixed ARCHFLAGS parsing on OS/X

Thomas Heller880f5292008-07-15 19:39:38 +00004485- Issue #3313: Fixed a crash when a failed dlopen() call does not set
4486 a valid dlerror() message.
4487
Thomas Heller2bad6572008-07-15 17:19:50 +00004488- Issue #3258: Fixed a crash when a ctypes POINTER type to an
4489 incomplete structure was created.
4490

4494
Andrew M. Kuchlingcc3f2b12008-07-10 14:43:31 +00004495- Issue #3301: Bisect module behaved badly when lo was negative.
Raymond Hettinger3cd1e422008-07-10 14:03:19 +00004496
Amaury Forgeot d'Arc0f7cddc2008-07-06 21:34:39 +00004497- Issue #839496: SimpleHTTPServer used to open text files in text mode. This is
4498 both unnecessary (HTTP allows text content to be sent in several forms) and
Andrew M. Kuchlingcc3f2b12008-07-10 14:43:31 +00004499 wrong because the actual transmitted size could differ from the
Amaury Forgeot d'Arc0f7cddc2008-07-06 21:34:39 +00004500 content-length. The problem had been corrected in the 2.4 branch, but never
4501 merged into trunk.
4502
Georg Brandle78fbcc2008-07-05 10:13:36 +00004503- Issue #2663: add filtering capability to shutil.copytree().

Andrew M. Kuchlingcc3f2b12008-07-10 14:43:31 +00004514 when completed.
Facundo Batista66c52772008-07-02 16:52:55 +00004515
Nick Coghlanc060b0e2008-07-02 13:09:19 +00004516- Issue #3190: Pydoc now hides the automatic module attribute __package__ (the
4517 handling is now the same as that of other special attributes like __name__).
4518
Brett Cannon8bb8fa52008-07-02 01:57:08 +00004519- Issue #2885 (partial): The urllib.urlopen() function has been deprecated for
4520 removal in Python 3.0 in favor of urllib2.urlopen().

Georg Brandl5cc774e2008-06-11 20:28:06 +00004909 PPC64 and x86_64 support in one binary).
Ronald Oussoren5640ce22008-06-05 12:58:24 +00004910
4911 This is controlled by the configure argument ``--with-universal-archs``:
4912
4913 - ``--with-universal-archs=all``: install 4-way universal
4914
4915 - ``--with-universal-archs=32-bit``: install 2-way universal, 32-bit (the default)
4916
4917 - ``--with-universal-archs=64-bit``: install 2-way universal, 64-bit
4918
4919 This option should be used in combination with ``--enable-universalsdk=``.
4920
4921 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 +00004971- Issue #1631171: Re-implement the 'warnings' module in C (the
4972 original Python code has been kept as backup). This will allow for
4973 using the 'warning's machinery in such places as the parser where
4974 use of pure Python code is not possible. Both the ``showarning()``
4975 and ``formatwarning()`` gain an optional 'line' argument which is
4976 not called by default for backwards-compatibility reasons. Setting
4977 ``warnings.showwarning()`` to an implementation that lacks support
4978 for the ``line`` argument will raise a DeprecationWarning.

Georg Brandl3ee81df2008-05-17 18:14:43 +00005041- Issue #2550: The approach used by client/server code for obtaining
5042 ports to listen on in network-oriented tests has been refined in an
5043 effort to facilitate running multiple instances of the entire
5044 regression test suite in parallel without issue.
5045 test_support.bind_port() has been fixed such that it will always
5046 return a unique port -- which wasn't always the case with the
5047 previous implementation, especially if socket options had been set
5048 that affected address reuse (i.e. SO_REUSEADDR, SO_REUSEPORT). The
5049 new implementation of bind_port() will actually raise an exception
5050 if it is passed an AF_INET/SOCK_STREAM socket with either the
5051 SO_REUSEADDR or SO_REUSEPORT socket option set. Furthermore, if
5052 available, bind_port() will set the SO_EXCLUSIVEADDRUSE option on
5053 the socket it's been passed. This currently only applies to
5054 Windows. This option prevents any other sockets from binding to the
5055 host/port we've bound to, thus removing the possibility of the
5056 'non-deterministic' behaviour, as Microsoft puts it, that occurs
5057 when a second SOCK_STREAM socket binds and accepts to a host/port
5058 that's already been bound by another socket. The optional preferred
5059 port parameter to bind_port() has been removed. Under no
5060 circumstances should tests be hard coding ports!
5061
5062 test_support.find_unused_port() has also been introduced, which will
5063 pass a temporary socket object to bind_port() in order to obtain an
5064 unused port. The temporary socket object is then closed and
5065 deleted, and the port is returned. This method should only be used
5066 for obtaining an unused port in order to pass to an external program
5067 (i.e. the -accept [port] argument to openssl's s_server mode) or as
5068 a parameter to a server-oriented class that doesn't give you direct
5069 access to the underlying socket used.
5070
5071 Finally, test_support.HOST has been introduced, which should be used
5072 for the host argument of any relevant socket calls (i.e. bind and
5073 connect).
Trent Nelsone41b0062008-04-08 23:47:30 +00005074
5075 The following tests were updated to following the new conventions:
Georg Brandl3ee81df2008-05-17 18:14:43 +00005076 test_socket, test_smtplib, test_asyncore, test_ssl, test_httplib,
Trent Nelsone41b0062008-04-08 23:47:30 +00005077 test_poplib, test_ftplib, test_telnetlib, test_socketserver,
5078 test_asynchat and test_socket_ssl.
5079
Georg Brandl3ee81df2008-05-17 18:14:43 +00005080 It is now possible for multiple instances of the regression test
5081 suite to run in parallel without issue.

Fred Drakea8ee94b2008-03-01 02:45:07 +00005350- Issue #2051: pyc and pyo files are no longer created with permission
Barry Warsaw52973612008-03-01 02:23:38 +00005351 644. The mode is now inherited from the py file.
Christian Heimes40346852008-02-23 17:52:07 +00005352
Georg Brandlad61bc82008-02-23 15:11:18 +00005353- Issue #2067: file.__exit__() now calls subclasses' close() method.
5354
5355- Patch #1759: Backport of PEP 3129 class decorators.
Christian Heimes5224d282008-02-23 15:01:05 +00005356
Vinay Sajipb7edfc42008-04-02 21:10:23 +00005357- Issue #1881: An internal parser limit has been increased. Also see
Georg Brandl222e2082010-08-01 22:27:39 +00005358 issue #215555 for a discussion.
Facundo Batistafc2d0102008-02-23 12:01:13 +00005359
Eric Smitha73fbe72008-02-23 03:09:44 +00005360- Added the future_builtins module, which contains hex() and oct().
5361 These are the PEP 3127 version of these functions, designed to be
5362 compatible with the hex() and oct() builtins from Python 3.0. They
5363 differ slightly in their output formats from the existing, unchanged
5364 Python 2.6 builtins. The expected usage of the future_builtins
5365 module is:
5366 from future_builtins import hex, oct
5367
Eric Smith7ef40bf2008-02-20 23:34:22 +00005368- Issue #1600: Modifed PyOS_ascii_formatd to use at most 2 digit
5369 exponents for exponents with absolute value < 100. Follows C99
5370 standard. This is a change on Windows, which would use 3 digits.
5371 Also, added 'n' to the formats that PyOS_ascii_formatd understands,
5372 so that any alterations it does to the resulting string will be
5373 available in stringlib/formatter.h (for float.__format__).
5374
Eric Smith5a3c1352008-02-19 13:21:56 +00005375- Implemented PEP 3101, Advanced String Formatting. This adds a new
5376 builtin format(); a format() method for str and unicode; a
5377 __format__() method to object, str, unicode, int, long, float, and
5378 datetime; the class string.Formatter; and the C API
5379 PyObject_Format().
5380
Georg Brandl3ee81df2008-05-17 18:14:43 +00005381- Fixed several potential crashes, all caused by specially crafted
5382 __del__ methods exploiting objects in temporarily inconsistent
5383 state.
Amaury Forgeot d'Arc632fad32008-02-16 20:55:24 +00005384
Vinay Sajipb7edfc42008-04-02 21:10:23 +00005385- Issue #2115: Important speedup in setting __slot__ attributes. Also
Georg Brandl3ee81df2008-05-17 18:14:43 +00005386 prevent a possible crash: an Abstract Base Class would try to access
5387 a slot on a registered virtual subclass.
Amaury Forgeot d'Arc60d6c7f2008-02-15 21:22:45 +00005388
Georg Brandl3ee81df2008-05-17 18:14:43 +00005389- Fixed repr() and str() of complex numbers with infinity or nan as
5390 real or imaginary part.
Christian Heimes2f0da532008-02-15 06:57:08 +00005391
Georg Brandl3ee81df2008-05-17 18:14:43 +00005392- Clear all free lists during a gc.collect() of the highest generation
5393 in order to allow pymalloc to free more arenas. Python may give back
5394 memory to the OS earlier.
Christian Heimes3b718a72008-02-14 12:47:33 +00005395
Georg Brandl3ee81df2008-05-17 18:14:43 +00005396- Issue #2045: Fix an infinite recursion triggered when printing a
5397 subclass of collections.defaultdict, if its default_factory is set
5398 to a bound method.
Amaury Forgeot d'Arcb01aa432008-02-08 00:56:02 +00005399
Christian Heimesf75dbef2008-02-08 00:11:31 +00005400- Fixed a minor memory leak in dictobject.c. The content of the free
5401 list was not freed on interpreter shutdown.
5402
Georg Brandl21e99f42010-03-07 15:23:59 +00005403- Limit free list of method and built-in function objects to 256
Georg Brandl3ee81df2008-05-17 18:14:43 +00005404 entries each.
Christian Heimes6075a822008-02-06 12:44:34 +00005405
Georg Brandl3ee81df2008-05-17 18:14:43 +00005406- Patch #1953: Added ``sys._compact_freelists()`` and the C API
5407 functions ``PyInt_CompactFreeList`` and ``PyFloat_CompactFreeList``
Christian Heimes422051a2008-02-04 18:00:12 +00005408 to compact the internal free lists of pre-allocted ints and floats.
5409
Georg Brandl3ee81df2008-05-17 18:14:43 +00005410- Issue #1983: Fixed return type of fork(), fork1() and forkpty()
5411 calls. Python expected the return type int but the fork familie
5412 returns pi_t.
Christian Heimes951cc0f2008-01-31 23:08:23 +00005413
Georg Brandl3ee81df2008-05-17 18:14:43 +00005414- Issue #1678380: Fix a bug that identifies 0j and -0j when they
5415 appear in the same code unit.
Mark Dickinson105be772008-01-31 22:17:37 +00005416
Georg Brandl3ee81df2008-05-17 18:14:43 +00005417- Issue #2025: Add tuple.count() and tuple.index() methods to comply
5418 with the collections.Sequence API.
Raymond Hettinger5b07ebc2008-02-07 00:54:20 +00005419
Georg Brandl3ee81df2008-05-17 18:14:43 +00005420- Patch #1970 by Antoine Pitrou: Speedup unicode whitespace and
5421 linebreak detection
Christian Heimes4d4f2702008-01-30 11:32:37 +00005422
Georg Brandl3ee81df2008-05-17 18:14:43 +00005423- Added ``PyType_ClearCache()`` and ``sys._clear_type_cache`` to clear
5424 the internal lookup cache for ref leak tests.
Christian Heimes908caac2008-01-27 23:34:59 +00005425
Georg Brandl3ee81df2008-05-17 18:14:43 +00005426- Patch #1473257: generator objects gain a gi_code attribute. This is
5427 the same object as the func_code attribute of the function that
5428 produced the generator.
Georg Brandl0cdf9a32008-01-26 14:14:20 +00005429
Georg Brandl3ee81df2008-05-17 18:14:43 +00005430- Issue #1920: "while 0" statements were completely removed by the
5431 compiler, even in the presence of an "else" clause, which is
5432 supposed to be run when the condition is false. Now the compiler
5433 correctly emits bytecode for the "else" suite.
Amaury Forgeot d'Arc31eaafe2008-01-24 22:59:25 +00005434
Guido van Rossumeead05f2008-01-24 18:21:02 +00005435- A few crashers fixed: weakref_in_del.py (issue #1377858);
5436 loosing_dict_ref.py (issue #1303614, test67.py);
5437 borrowed_ref_[34].py (not in tracker).
5438
Vinay Sajipd7cf32e2008-01-24 12:43:33 +00005439- Issue #1069410: The "can't load dll" message box on Windows is
Christian Heimesb2302ba2008-01-23 17:15:06 +00005440 suppressed while an extension is loaded by calling SetErrorMode in
5441 dynload_win.c. The error is still reported properly.
5442
Georg Brandl3ee81df2008-05-17 18:14:43 +00005443- Issue #1915: Python compiles with --enable-unicode=no again. However
Christian Heimes082c9b02008-01-23 14:20:50 +00005444 several extension methods and modules do not work without unicode
5445 support.
5446
Georg Brandl26543b12008-01-21 18:36:51 +00005447- Issue #1882: when compiling code from a string, encoding cookies in the
5448 second line of code were not always recognized correctly.
5449
Georg Brandl14404b62008-01-19 19:27:05 +00005450- Issue #1679: "0x" was taken as a valid integer literal.
5451
Georg Brandl6caad7d2008-01-26 14:19:22 +00005452- Issue #1865: ``bytes`` as an alias for ``str`` and b"" as an alias "" were
Christian Heimes288e89a2008-01-18 18:24:07 +00005453 added.
5454
Christian Heimesc94e2b52008-01-14 04:13:37 +00005455- sys.float_info / PyFloat_GetInfo: The floating point information
5456 object was converted from a dict to a specialized structseq object.
5457
Georg Brandl3ee81df2008-05-17 18:14:43 +00005458- Patch #1816: Added sys.flags structseq. It exposes the status of
5459 most command line arguments and PYTHON* environment variables.
Christian Heimesf31b69f2008-01-14 03:42:48 +00005460
Georg Brandl3ee81df2008-05-17 18:14:43 +00005461- Objects/structseq.c: Implemented new structseq representation. The
5462 patch makes structseqs (e.g. the return value of os.stat) more
5463 readable.
Christian Heimes9c201962008-01-14 03:33:52 +00005464
Georg Brandl3ee81df2008-05-17 18:14:43 +00005465- Patch #1700288: added a type attribute cache that caches method
5466 accesses, resulting in speedups in heavily object-oriented code.
Amaury Forgeot d'Arce4c270c2008-01-14 00:29:41 +00005467
Neal Norwitz3fc15b82008-01-10 05:42:58 +00005468- Bug #1776: __import__() no longer accepts filenames on any platform.
5469 The first parameter to __import__() must be a valid module name.
Christian Heimes3403f152008-01-09 19:56:33 +00005470

5472
Georg Brandl3ee81df2008-05-17 18:14:43 +00005473- Patch #602345: Add -B command line option, PYTHONDONTWRITEBYTECODE
5474 envvar and sys.dont_write_bytecode attribute. All these can be set
5475 to forbid Python to attempt to write compiled bytecode files.
Georg Brandl2da0fce2008-01-07 17:09:35 +00005476
Georg Brandl3ee81df2008-05-17 18:14:43 +00005477- Improve some exception messages when Windows fails to load an
5478 extension module. Now we get for example '%1 is not a valid Win32
5479 application' instead of 'error code 193'.
Amaury Forgeot d'Arce0b76952008-01-04 02:04:15 +00005480
Georg Brandl3ee81df2008-05-17 18:14:43 +00005481- Bug #1481296: Fixed long(float('nan')) != 0L.

Georg Brandl3ee81df2008-05-17 18:14:43 +00005483- Issue #1640: Added math.isinf(x), math.isnan(x) and math.copysign(x,
5484 y) functions.
Christian Heimese2ca4242008-01-03 20:23:15 +00005485
Christian Heimes0a8143f2007-12-18 23:22:54 +00005486- Issue #1635: Platform independent creation and representation of NaN
Georg Brandl3ee81df2008-05-17 18:14:43 +00005487 and INF. float("nan"), float("inf") and float("-inf") now work on
5488 every platform with IEEE 754 semantics.
Christian Heimes0a8143f2007-12-18 23:22:54 +00005489
Georg Brandl3ee81df2008-05-17 18:14:43 +00005490- Compiler now generates simpler and faster code for dictionary
5491 literals. The oparg for BUILD_MAP now indicates an estimated
5492 dictionary size. There is a new opcode, STORE_MAP, for adding
5493 entries to the dictionary.
Raymond Hettingerfd7ed402007-12-18 21:24:09 +00005494

5523 file can now be directly executed by passing their name to the
5524 interpreter. The directory/zipfile is automatically inserted as the
5525 first entry in sys.path.
Nick Coghlan327a39b2007-11-18 11:56:28 +00005526
Georg Brandl3ee81df2008-05-17 18:14:43 +00005527- Issue #1265: Fix a problem with sys.settrace, if the tracing
5528 function uses a generator expression when at the same time the
5529 executed code is closing a paused generator.
Amaury Forgeot d'Arc0d75f092007-11-13 21:54:28 +00005530
Raymond Hettinger1760c8a2007-11-08 02:52:43 +00005531- sets and frozensets now have an isdisjoint() method.
5532
Raymond Hettinger3f8caa32007-10-24 01:28:33 +00005533- optimize the performance of builtin.sum().

Neal Norwitz44f326e2007-10-05 05:29:17 +00005535- Fix warnings found by the new version of the Coverity checker.
5536
Georg Brandl21e99f42010-03-07 15:23:59 +00005537- The enumerate() built-in function is no longer bounded to sequences
Georg Brandl3ee81df2008-05-17 18:14:43 +00005538 smaller than LONG_MAX. Formerly, it raised an OverflowError. Now,
5539 automatically shifts from ints to longs.
Raymond Hettinger8f669372007-10-03 21:18:11 +00005540
Georg Brandl3ee81df2008-05-17 18:14:43 +00005541- Issue #1686386: Tuple's tp_repr did not take into account the
5542 possibility of having a self-referential tuple, which is possible
5543 from C code. Nor did object's tp_str consider that a type's tp_str
5544 could do something that could lead to an inifinite recursion.
5545 Py_ReprEnter() and Py_EnterRecursiveCall(), respectively, fixed the
5546 issues.
Brett Cannon0b14f242007-09-30 19:45:10 +00005547
Georg Brandl3ee81df2008-05-17 18:14:43 +00005548- Issue #1164: It was possible to trigger deadlock when using the
5549 'print' statement to write to a file since the GIL was not released
5550 as needed. Now PyObject_Print() does the right thing along with
5551 various tp_print implementations of the built-in types and those in
5552 the collections module.
Brett Cannon01531592007-09-17 03:28:34 +00005553
Georg Brandl3ee81df2008-05-17 18:14:43 +00005554- Issue #1147: Exceptions were directly allowing string exceptions in
5555 their throw() method even though string exceptions no longer
5556 allowed.
Brett Cannon4c20bc42007-09-11 21:02:28 +00005557

Brett Cannon1e534b52007-09-07 04:18:30 +00005561- Issue #1202533: Fix infinite recursion calls triggered by calls to
Georg Brandl3ee81df2008-05-17 18:14:43 +00005562 PyObject_Call() never calling back out to Python code to trigger
5563 recursion depth updates/checks. Required the creation of a static
5564 RuntimeError instance in case normalizing an exception put the
5565 recursion check value past its limit. Fixes crashers
5566 infinite_rec_(1|2|4|5).py.
Brett Cannon1e534b52007-09-07 04:18:30 +00005567

Neal Norwitz0ac60192007-05-27 04:08:54 +00005581- Add new attribute names for function objects. All the func_* become
Georg Brandl3ee81df2008-05-17 18:14:43 +00005582 __*__ attributes. (Some already existed, e.g., __doc__ and
5583 __name__.)
Neal Norwitz0ac60192007-05-27 04:08:54 +00005584
Neal Norwitz8b2bfbc2007-05-23 06:35:32 +00005585- Add -3 option to the interpreter to warn about features that are
5586 deprecated and will be changed/removed in Python 3.0.
5587
Georg Brandl2134e752007-05-21 20:34:16 +00005588- Patch #1686487: you can now pass any mapping after '**' in function
5589 calls.

Georg Brandl3ee81df2008-05-17 18:14:43 +00005592 "except E as target:". This is to provide forwards compatibility
5593 with Python 3.0.

5613
Guido van Rossum143b5642007-03-23 04:58:42 +00005614- Bug #1683368: The object.__init__() and object.__new__() methods are
5615 now stricter in rejecting excess arguments. The only time when
5616 either allows excess arguments is when it is not overridden and the
5617 other one is. For backwards compatibility, when both are
5618 overridden, it is a deprecation warning (for now; maybe a Py3k
Guido van Rossum234b1ff2007-03-23 19:39:01 +00005619 warning later). Also, type.__init__() insists on the same signature
5620 as supported by type.__new__().

Georg Brandl3ee81df2008-05-17 18:14:43 +00005622- Patch #1675423: PyComplex_AsCComplex() now tries to convert an
5623 object to complex using its __complex__() method before falling back
5624 to the __float__() method. Therefore, the functions in the cmath
5625 module now can operate on objects that define a __complex__()
5626 method.

5646
Georg Brandl871f1bc2007-03-12 13:17:36 +00005647- The dir() function has been extended to call the __dir__() method on
Georg Brandl3ee81df2008-05-17 18:14:43 +00005648 its argument, if it exists. If not, it will work like before. This
5649 allows customizing the output of dir() in the presence of a

5660 raising a ValueError.

Georg Brandlaa2321b2007-03-07 00:40:28 +00005662- Patch #703779: unset __file__ in __main__ after running a file. This
Georg Brandl3ee81df2008-05-17 18:14:43 +00005663 makes the filenames the warning module prints much more sensible
5664 when a PYTHONSTARTUP file is used.

Georg Brandl3ee81df2008-05-17 18:14:43 +00006592- Issue #829951: In the smtplib module, SMTP.starttls() now complies
6593 with RFC 3207 and forgets any knowledge obtained from the server not
6594 obtained from the TLS negotiation itself. Patch contributed by Bill
6595 Fenner.
Gregory P. Smith2b3ba582008-01-17 08:03:17 +00006596
Georg Brandl3ee81df2008-05-17 18:14:43 +00006597- Issue #1339: The smtplib.SMTP class has been refactored a bit such
Gregory P. Smithbde4ae42008-01-17 08:35:49 +00006598 that the SMTP.starttls() caller no longer needs to call ehlo()
6599 beforehand. SMTP.starttls() now raises an exception of the server
Georg Brandl3ee81df2008-05-17 18:14:43 +00006600 does not claim to support starttls. Adds the
6601 SMTP.ehlo_or_helo_if_needed() method. Patch contributed by Bill

6682 complex, tuple, list, dict, set, and frozenset. Formerly, it would
6683 silently miscode subclasses of those types. Now, it raises a
6684 ValueError instead.
Raymond Hettinger12e94202007-11-07 01:13:09 +00006685

Georg Brandl3ee81df2008-05-17 18:14:43 +00006700 time so that opening a database previously created with the DB_DUP
6701 or DB_DUPSORT flag set will keep the proper behavior on subsequent
6702 opens. Specifically: dictionary assignment to a DB object will
6703 replace all values for a given key when the database allows
6704 duplicate values. DB users should use DB.put(k, v) when they want
6705 to store duplicates; not DB[k] = v.
Gregory P. Smithec10a4a2007-11-05 02:32:26 +00006706

6712 characters with ASCII value less than 32. Also, it correctly quotes
6713 dots only if they occur on a single line, as opposed to the previous
6714 behavior of quoting dots if they are the second character of any
6715 line.
Georg Brandl4aef7272007-03-13 22:49:43 +00006716

Georg Brandl3ee81df2008-05-17 18:14:43 +00007060- Issue #1521: On 64bit platforms, using PyArgs_ParseTuple with the t#
7061 of w# format code incorrectly truncated the length to an int, even
7062 when PY_SSIZE_T_CLEAN is set. The str.decode method used to return
7063 incorrect results with huge strings.

Georg Brandl3ee81df2008-05-17 18:14:43 +00007065- Issue #1629: Renamed Py_Size, Py_Type and Py_Refcnt to Py_SIZE,
7066 Py_TYPE and Py_REFCNT.

Georg Brandl3ee81df2008-05-17 18:14:43 +00007068- PEP 3123: Provide forward compatibility with Python 3.0, while
7069 keeping backwards compatibility. Add Py_Refcnt, Py_Type, Py_Size,
7070 and PyVarObject_HEAD_INIT.

Georg Brandl3ee81df2008-05-17 18:14:43 +00007072- Py_ssize_t fields work in structmember when HAVE_LONG_LONG is not
7073 defined.

7075- Patch #1733960: Allow T_LONGLONG to accept ints.
7076
7077- T_PYSSIZET can now be used in PyMemberDef lists for Py_ssize_t members.

7082
7083- Fix some leftovers from the conversion from int to Py_ssize_t
7084 (relevant to strings and sequences of more than 2**31 items).
7085
7086- Make _PyGILState_NoteThreadState() static, it was not used anywhere
7087 outside of pystate.c and should not be necessary.
7088
Georg Brandl3ee81df2008-05-17 18:14:43 +00007089- ``PyImport_Import`` and ``PyImport_ImportModule`` now always do

Georg Brandl3ee81df2008-05-17 18:14:43 +00007093- Added case insensitive comparison methods ``PyOS_stricmp(char*,
7094 char*)`` and ``PyOS_strnicmp(char*, char*, Py_ssize_t)``.
Christian Heimes000a0742008-01-03 22:16:32 +00007095
Georg Brandl3ee81df2008-05-17 18:14:43 +00007096- Bug #1542693: remove semi-colon at end of PyImport_ImportModuleEx

Georg Brandl3ee81df2008-05-17 18:14:43 +00007103- Patch #1706: Drop support for Win9x, WinME and NT4. Python now
7104 requires Windows 2000 or greater. The _WINVER and NTDDI_VERSION
7105 macros are set to Win2k for x86/32bit builds and WinXP for AMD64
7106 builds.

Georg Brandl3ee81df2008-05-17 18:14:43 +00007121- Removed the macfs module. It had been deprecated since Python 2.5.
7122 This lead to the deprecation of macostools.touched() as it relied
7123 solely on macfs and was a no-op under OS X.
