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

1196 E.g.: '\xf1\x80AB'.decode('utf-8', 'replace') now returns u'\ufffdAB' and
1197 replaces with U+FFFD only the start byte ('\xf1') and the continuation byte
1198 ('\x80') even if '\xf1' is the start byte of a 4-bytes sequence.
1199 Previous versions returned a single u'\ufffd'.

1209 (2**53+1 == complex(2**53) == 2**53), breaking transivity of equality.

1459 indefinitely if the other end didn't respond.
1460
Georg Brandlfee0f442010-05-22 21:26:21 +00001461- The do_handshake() method of SSL objects now adjusts the blocking mode of the

Mark Dickinsond2f3e3f2010-05-05 22:23:58 +00001554 (Optimization was unintentionally turned on in gcc --with-pydebug builds in

Philip Jenveyaebbaeb2010-04-06 23:24:45 +00001579- Issue #7301: Add environment variable $PYTHONWARNINGS.
1580
Benjamin Peterson3a1dfa22010-04-06 21:50:00 +00001581- Issue #8329: Don't return the same lists from select.select when no fds are
1582 changed.
1583
Georg Brandlfee0f442010-05-22 21:26:21 +00001584- Issue #8259: ``1L << (2**31)`` no longer produces an 'outrageous shift error'
Mark Dickinson82791672010-04-06 16:47:55 +00001585 on 64-bit machines. The shift count for either left or right shift is
1586 permitted to be up to sys.maxsize.

Georg Brandlfee0f442010-05-22 21:26:21 +00001594- Issue #7994: Issue a PendingDeprecationWarning if object.__format__ is called
1595 with a non-empty format string. This is an effort to future-proof user
1596 code. If a derived class does not currently implement __format__ but later
1597 adds its own __format__, it would most likely break user code that had
Antoine Pitrou01a196a2011-01-02 20:05:11 +00001598 supplied a format string. This will be changed to a DeprecationWarning in
Georg Brandlfee0f442010-05-22 21:26:21 +00001599 Python 3.3 and it will be an error in Python 3.4.

Georg Brandlfee0f442010-05-22 21:26:21 +00001632- Issue #8257: The Decimal construct now accepts a float instance directly,

Georg Brandlfee0f442010-05-22 21:26:21 +00001649- Issue #7279: Comparisons involving a Decimal signaling NaN now signal
1650 InvalidOperation instead of returning False. (Comparisons involving a quiet
1651 NaN are unchanged.) Also, Decimal quiet NaNs are now hashable; Decimal
1652 signaling NaNs remain unhashable.
Mark Dickinsone096e822010-04-02 10:17:07 +00001653
Georg Brandlfee0f442010-05-22 21:26:21 +00001654- Issue #2531: Comparison operations between floats and Decimal instances now
1655 return a result based on the numeric values of the operands; previously they
1656 returned an arbitrary result based on the relative ordering of id(float) and
1657 id(Decimal).

Georg Brandlfee0f442010-05-22 21:26:21 +00001671- Comparisons using one of <, <=, >, >= between a complex instance and a
1672 Fractions instance now raise TypeError instead of returning True/False. This
1673 makes Fraction <=> complex comparisons consistent with int <=> complex, float
1674 <=> complex, and complex <=> complex comparisons.

Georg Brandlba83f822010-03-14 09:50:54 +00002092 file position when calling `truncate()`. It would previously change the file
2093 position to the given argument, which goes against the tradition of
Antoine Pitrouf3fa0742010-01-31 22:26:04 +00002094 ftruncate() and other truncation APIs. Patch by Pascal Chambon.

2097 class used to represent files stored inside an archive. The new
2098 implementation is significantly faster and can be wrapped in a

2100 where interleaved calls to ``read()`` and ``readline()`` give wrong results.

Georg Brandlba83f822010-03-14 09:50:54 +00002191- The ``__complex__()`` method is now looked up on the class of instances to
2192 make it consistent with other special methods.
Benjamin Petersonecdae192010-01-04 00:43:01 +00002193
Antoine Pitrou5b7139a2010-01-02 21:12:58 +00002194- Issue #7462: Implement the stringlib fast search algorithm for the `rfind`,

2196
Mark Dickinson1b34d252010-01-01 17:27:30 +00002197- Issue #5080: A number of functions and methods previously produced a
Georg Brandlba83f822010-03-14 09:50:54 +00002198 DeprecationWarning when passed a float argument where an integer was expected.
2199 These functions and methods now raise TypeError instead. The majority of the
2200 effects of this change are in the extension modules, but some core functions
2201 and methods are affected: notably the 'chr', 'range' and 'xrange' builtins,
2202 and many unicode/str methods.

2214
Georg Brandlba83f822010-03-14 09:50:54 +00002215- Issue #1811: Improve accuracy and cross-platform consistency for true division
2216 of integers: the result of a/b is now correctly rounded for ints a and b (at
2217 least on IEEE 754 platforms), and in particular does not depend on the
2218 internal representation of a long.
Mark Dickinson46572832009-12-27 14:55:57 +00002219
Georg Brandlba83f822010-03-14 09:50:54 +00002220- Issue #6108: ``unicode(exception)`` and ``str(exception)`` should return the

Ronald Oussoren92919a62009-12-24 13:30:58 +00002225 executables on OSX.
2226
Georg Brandlba83f822010-03-14 09:50:54 +00002227 These executables now work properly with the arch(1) command: ``arch -ppc
2228 python`` will start a universal binary version of python in PPC mode (unlike
2229 previous releases).

Georg Brandlba83f822010-03-14 09:50:54 +00002252 renaming of `cPickle` to `pickle`. The warning was annoying since there's no

Georg Brandlba83f822010-03-14 09:50:54 +00002392- Issue #7117: On almost all platforms: float-to-string and string-to-float
2393 conversions within Python are now correctly rounded. Places these conversions
2394 occur include: str for floats and complex numbers; the float and complex
2395 constructors; old-style and new-style numeric formatting; serialization and
2396 deserialization of floats and complex numbers using marshal, pickle and json;
2397 parsing of float and imaginary literals in Python code; Decimal-to-float
2398 conversion.
Mark Dickinsonb678de82009-11-19 18:41:49 +00002399
Georg Brandlba83f822010-03-14 09:50:54 +00002400 The conversions use a Python-adapted version of David Gay's well-known dtoa.c,
2401 providing correctly-rounded strtod and dtoa C functions. This code is
2402 supported on Windows, and on Unix-like platforms using gcc, icc or suncc as
2403 the C compiler. There may be a small number of platforms on which correct
2404 operation of this code cannot be guaranteed, so the code is not used: notably,
2405 this applies to platforms where the C double format is not IEEE 754 binary64,
2406 and to platforms on x86 hardware where the x87 FPU is set to 64-bit precision
2407 and Python's configure script is unable to determine how to change the FPU
2408 precision. On these platforms conversions use the platform strtod and dtoa,
2409 as before.

Georg Brandlba83f822010-03-14 09:50:54 +00002411- Issue #7117: Backport round implementation from Python 3.x. ``round()`` now
2412 uses the correctly-rounded string <-> float conversions described above (when
2413 available), and so produces correctly rounded results that will display nicely
2414 under the float repr. There are two related small changes: (1) round now
2415 accepts any class with an ``__index__()`` method for its second argument (but
2416 no longer accepts floats for the second argument), and (2) an excessively
2417 large second integer argument (e.g., ``round(1.234, 10**100)``) no longer
2418 raises an exception.

4000 'b', 'B', 'h', 'H', 'i', 'l', '*b', '*h' ,'*i', '*l', and an x with a
4001 __long__ method could be packed by 'q', 'Q', '*q', '*Q'; for x with
4002 neither __int__ nor __long__, TypeError used to be raised (with a
4003 confusing error message) for 'I', 'L', '*B', '*H', '*I', '*L', and
4004 struct.error in other cases.

4007 argument with an __int__ method can be packed, but use of this feature

Amaury Forgeot d'Arc05e34492008-09-10 22:04:45 +00004201- Issue #3743: In a few places, PY_FORMAT_SIZE_T was incorrectly used with

4203 PY_FORMAT_SIZE_T is designed to select the correct format for the OS
4204 ``printf`` function, whereas PyString_FromFormat has an independent

Brett Cannon1eaf0742008-09-02 01:25:16 +00004302 warnings.catch_warnings() along with some API cleanup. Expanding the tests
4303 for catch_warnings() also led to an improvement in the raising of a
4304 DeprecationWarning related to warnings.warn_explicit().

Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00004370What's New in Python 2.6 beta 3?
4371================================
4372
Barry Warsaw07a4a382008-08-21 01:15:08 +00004373*Release date: 20-Aug-2008*
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00004374
4375Core and Builtins
4376-----------------
4377
Guido van Rossumf8402962008-08-20 15:01:50 +00004378- Issue #1878: Remove Py_TPFLAGS_HAVE_VERSION_TAG from
4379 Py_TPFLAGS_DEFAULT when not building the core. This means 3rd party
4380 extensions do not automatically benefit from the class attribute
4381 cache; they will have to explicitly add Py_TPFLAGS_HAVE_VERSION_TAG
4382 to their tp_flags field if they care. This is a backwards
4383 compatibility feature; in 3.0, all types will use the cache by
4384 default.
4385
Benjamin Petersonf647dc12008-08-20 01:27:30 +00004386- Keyword arguments can now follow starred arguments. (``f(a, *args,
4387 keyword=23)`` is now valid syntax.)
4388
Thomas Heller0ad5ae02008-08-19 19:25:04 +00004389- ctypes function pointers that are COM methods have a boolean True
4390 value again.
4391
Martin v. Löwisf91d46a2008-08-12 14:49:50 +00004392- Issue #3139: Make buffer-interface thread-safe wrt. PyArg_ParseTuple,
4393 by denying s# to parse objects that have a releasebuffer procedure,
4394 and introducing s*.
4395
Georg Brandl1e13ea92008-08-11 09:07:59 +00004396- Issue #3537: Fix an assertion failure when an empty but presized dict
4397 object was stored in the freelist.
4398
Mark Dickinsonb6467572008-08-04 21:30:09 +00004399- Issue #1481296: Make long(float('nan')) and int(float('nan')) raise
4400 ValueError consistently across platforms.
4401
Amaury Forgeot d'Arc39fd6722008-07-31 21:28:03 +00004402- Issue #3479: On platforms where sizeof(int) is smaller than sizeof(long)
4403 (64bit Unix, for example), unichr() would truncate its argument and return
4404 u'\x00' for unichr(2**32). Now it properly raises an OverflowError.
4405
Neal Norwitze7d8be82008-07-31 17:17:14 +00004406- Apply security patches from Apple.
4407
Amaury Forgeot d'Arc246daed2008-07-31 00:42:16 +00004408- Issue #2542: Now that issubclass() may call arbitrary code, ensure that
4409 PyErr_ExceptionMatches returns 0 when an exception occurs there.
4410
Antoine Pitrou92f82162008-07-25 22:22:08 +00004411- Issue #1819: function calls with several named parameters are now on
4412 average 35% faster (as measured by pybench).
4413
Amaury Forgeot d'Arce4921fe2008-07-21 22:00:38 +00004414- Issue #2378: An unexpected UnboundLocalError or NameError could appear when
4415 the python debugger steps into a class statement: the free variables (local
4416 variables defined in an outer scope) would be deleted from the outer scope.
4417
Gregory P. Smith0470bab2008-07-22 04:46:32 +00004418- Issue #2620: Overflow checking when allocating or reallocating memory
4419 was not always being done properly in some python types and extension
4420 modules. PyMem_MALLOC, PyMem_REALLOC, PyMem_NEW and PyMem_RESIZE have
4421 all been updated to perform better checks and places in the code that
4422 would previously leak memory on the error path when such an allocation
4423 failed have been fixed.

4426-------
4427
Hirokazu Yamamoto838c79f2008-08-20 13:14:07 +00004428- Issue #3612: Added some missing basic types in ctypes.wintypes.
4429
Benjamin Petersone977ad42008-08-20 01:42:01 +00004430- The methods ``is_in_tuple()``, ``is_vararg()``, and ``is_keywordarg()`` of
4431 symtable.Symbol have been deprecated for removal in 3.0 and the next release.
4432
Amaury Forgeot d'Arc351ffb82008-08-18 19:23:47 +00004433- Issue #2234: distutils failed for some versions of the cygwin compiler. The
4434 version reported by these tools does not necessarily follow the python
4435 version numbering scheme, so the module is less strict when parsing it.
4436
Nick Coghlanf70385a2008-08-18 12:42:46 +00004437- Issue #2235: Added Py3k warnings for types which will become unhashable
4438 under the stricter __hash__ inheritance rules in 3.0. Several types
4439 which did not meet the rules for hash invariants and were already
4440 unhashable in 3.0 have now been explicitly flagged as unhashable in
4441 2.6 as well (collections.Mapping, collections.Set, unittest.TestSuite,
4442 xml.dom.minidom.NamedNodeMap, numbers.Number, UserList.UserList)
4443
Brett Cannon88f801d2008-08-18 00:46:22 +00004444- Update __all__ for cookielib, csv, os, urllib2, and weakref to include things
4445 imported into the module but exposed as part of the module's API.
4446
Brett Cannon7b96f072008-08-18 00:41:11 +00004447- Remove an unneeded import of abc.ABCMeta from 'inspect'.
4448
Brett Cannon46225e72008-08-18 00:36:52 +00004449- Remove unneeded imports of 'sys' and 'warnings' from 'io'.

Brett Cannon25c9d6a2008-08-17 22:10:11 +00004451- Remove unneeded imports of 'warnings' from shelve, filecmp, and dummy_thread.
4452
Hirokazu Yamamoto41a81eb2008-08-17 13:10:46 +00004453- Issue #3575: Incremental decoder's decode function now takes bytearray
4454 by using 's*' instead of 't#'.
4455
Mark Dickinson3e4caeb2009-02-21 20:27:01 +00004456- Issue #2222: Fixed reference leak when occurred os.rename()
Hirokazu Yamamoto7f30a682008-08-17 09:46:56 +00004457 fails unicode conversion on 2nd parameter. (windows only)
4458
Georg Brandl222e2082010-08-01 22:27:39 +00004459- Issue #2464: urllib2 now supports a malformation in the URL received
Facundo Batista94f243a2008-08-17 03:38:39 +00004460 in a redirect.
4461
Brett Cannonabe423e2008-08-16 21:47:07 +00004462- Silence the DeprecationWarning raised when importing mimetools in
Brett Cannon721b1452008-08-16 22:00:27 +00004463 BaseHTTPServer, cgi (and rfc822), httplib.
Brett Cannonabe423e2008-08-16 21:47:07 +00004464
Facundo Batistaeb90b782008-08-16 14:44:07 +00004465- Issue #2776: fixed small issue when handling an URL with double slash
4466 after a 302 response in the case of not going through a proxy.
4467
Antoine Pitroub90a8be2008-08-15 21:03:21 +00004468- Issue #2676: in the email package, content-type parsing was hanging on
4469 pathological input because of quadratic or exponential behaviour of a
4470 regular expression.
4471
Antoine Pitrou11ec65d2008-08-14 21:04:30 +00004472- Issue #3476: binary buffered reading through the new "io" library is now
4473 thread-safe.
4474
Brett Cannonbf3157b2008-08-14 05:00:03 +00004475- Silence the DeprecationWarning of rfc822 when it is imported by mimetools
4476 since mimetools itself is deprecated. Because modules are cached, all
4477 subsequent imports of rfc822 will not raise a visible DeprecationWarning.
4478
Antoine Pitrou9fcd4b32008-08-11 17:21:36 +00004479- Issue #3134: shutil referenced undefined WindowsError symbol.
4480
Robert Schuppenies14646332008-08-10 11:01:53 +00004481- Issue #1342811: Fix leak in Tkinter.Menu.delete. Commands associated to
4482 menu entries were not deleted.
4483
Brett Cannon83e81842008-08-09 23:30:55 +00004484- Copied the implementation of reduce() to _functools.reduce() to have a
4485 version that did not raise a DeprecationWarning under -3.
4486
Antoine Pitrou76b8bee2008-08-09 17:27:23 +00004487- Issue #3205: When iterating over a BZ2File fails allocating memory, raise
4488 a MemoryError rather than silently stop the iteration.
4489
Guido van Rossum59ce9012008-08-09 14:55:34 +00004490- Issue #3487: sre "bytecode" validator. Passing invalid "re-bytecode"
4491 to _sre.compile() will now be rejected. This should not affect anybody
4492 since the re.compile() function never generates invalid re-bytecode.
4493
Skip Montanaroa032bf42008-08-08 22:52:51 +00004494- Issue #3436: Make csv.DictReader's fieldnames attribute a property so that
4495 upon first access it can be automatically initialized from the csv file if
4496 it wasn't initialized during instantiation.
4497
Brett Cannon3aa2a492008-08-06 22:28:09 +00004498- Issue #2338: Create imp.reload() to help with transitioning to Python 3.0 as
4499 the reload() built-in has been removed.
4500
Brett Cannon7e30b672008-08-04 21:52:25 +00004501- Changed code in the following modules/packages to remove warnings raised
Brett Cannonc1b76e42008-08-09 23:06:16 +00004502 while running under the ``-3`` flag: aifc, asynchat, asyncore, bdb, bsddb,

Antoine Pitroude781a42008-08-09 12:43:23 +00004513 asking for a specific length. This problem only affected files opened
4514 using the new "io" module, not the built-in open() function.
Benjamin Peterson01a24322008-07-28 23:35:27 +00004515

4542
Gregory P. Smitha36f8fe2008-08-04 00:13:29 +00004543- Issue #1857: subprocess.Popen.poll gained an additional _deadstate keyword

4565================================
4566
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00004567*Release date: 17-Jul-2008*

Raymond Hettingere3ae6552008-06-20 04:18:15 +00004569Core and Builtins
4570-----------------
4571
Georg Brandl3e483f62008-07-16 22:57:41 +00004572- Issue #3156: Fix inconsistent behavior of the bytearray type: all
4573 its methods now allow for items objects that can be converted to
4574 an integer using operator.index().
4575
Mark Dickinson64b7e502008-07-16 09:40:03 +00004576- Issue #3360: Fix incorrect parsing of '020000000000.0', which
4577 produced a ValueError instead of giving the correct float.
4578
Eric Smitha5fa5a22008-07-16 00:11:49 +00004579- Issue #3083: Add alternate (#) formatting for bin, oct, hex output
4580 for str.format(). This adds the prefix 0b, 0o, or 0x, respectively.
4581
Mark Dickinson7103aa42008-07-15 19:08:33 +00004582- Issue #3008: the float type has a new instance method 'float.hex'
4583 and a new class method 'float.fromhex' to convert floating-point
4584 numbers to and from hexadecimal strings, respectively.
4585
Nick Coghlan6d6bd442008-07-15 15:40:22 +00004586- Issue #2235: __hash__ is once again inherited by default. To allow
4587 collections.Hashable to remain meaningful in the presence of the
4588 default hash implementation (object.__hash__), it is now possible
4589 to explicit block inheritance of hash by setting __hash__=None at
4590 the Python level, or tp_hash=PyObject_HashNotImplemented at the C
4591 level.
4592
Nick Coghlanb028f502008-07-13 14:52:36 +00004593- Issue #3221: Issue a RuntimeWarning instead of raising SystemError if
4594 the parent module cannot be found while performing an absolute import.
4595 This means that an incorrectly defined __package__ attribute will
4596 now only prevent relative imports in that module rather than causing
4597 all imports from that module to fail.
4598
Nick Coghlan14ff9942008-07-08 14:21:42 +00004599- Issue #2517: Allow unicode messages in Exceptions again by correctly
4600 bypassing the instance dictionary when looking up __unicode__ on
4601 new-style classes.

4604 set to a custom object whose write() method happens to install
4605 another file in sys.stdout.
4606
Amaury Forgeot d'Arc1f40c8a2008-06-30 22:42:40 +00004607- Issue #3088: Corrected a race condition in classes derived from
4608 threading.local: the first member set by a thread could be saved in
4609 another thread's dictionary.
4610
Mark Dickinson1ec2fcd2008-06-20 14:53:43 +00004611- Issue #3004: Minor change to slice.indices(): the start and stop
4612 arguments are now treated identically, making the behaviour easier
4613 to describe and understand. For example, slice(None, -10,
4614 1).indices(9) now returns (0, 0, 1) instead of (0, -1, 1), and
4615 slice(None, 10, -1).indices(10) returns (9, 9, -1) instead of (9,
4616 10, -1).
4617
Georg Brandl278fc502008-07-19 12:46:12 +00004618- Issue #3219: Calling a function with repeated keyword arguments,
4619 f(a=2, a=23), would not cause a syntax error. This was a regression
4620 from 2.4 caused by the switch to the new compiler.
Benjamin Peterson175e4d92008-07-01 19:34:52 +00004621
Georg Brandl278fc502008-07-19 12:46:12 +00004622- Issue #2862: Make int and float freelist management consistent with
4623 other freelists. Changes their CompactFreeList apis into
4624 ClearFreeList apis and calls them via gc.collect().

Thomas Heller57adf222008-08-14 19:10:48 +00004629- Issue #3554: ctypes.string_at and ctypes.wstring_at did call Python
4630 api functions without holding the GIL, which could lead to a fatal
4631 error when they failed.
4632
Martin v. Löwisaabf4042008-08-02 07:20:25 +00004633- Issue #799428: Fix Tkinter.Misc._nametowidget to unwrap Tcl command objects.

4642 ForkingPickler.register() to resolve conflict with ctypes.
4643
Vinay Sajip51e65192008-07-18 09:01:10 +00004644- Issue #3090: Fixed ARCHFLAGS parsing on OS/X
Jesse Noller13e9d582008-07-16 14:32:36 +00004645
Thomas Heller880f5292008-07-15 19:39:38 +00004646- Issue #3313: Fixed a crash when a failed dlopen() call does not set
4647 a valid dlerror() message.

4655
Andrew M. Kuchlingcc3f2b12008-07-10 14:43:31 +00004656- Issue #3301: Bisect module behaved badly when lo was negative.
Raymond Hettinger3cd1e422008-07-10 14:03:19 +00004657
Amaury Forgeot d'Arc0f7cddc2008-07-06 21:34:39 +00004658- Issue #839496: SimpleHTTPServer used to open text files in text mode. This is
4659 both unnecessary (HTTP allows text content to be sent in several forms) and
Andrew M. Kuchlingcc3f2b12008-07-10 14:43:31 +00004660 wrong because the actual transmitted size could differ from the
Amaury Forgeot d'Arc0f7cddc2008-07-06 21:34:39 +00004661 content-length. The problem had been corrected in the 2.4 branch, but never
4662 merged into trunk.
4663
Georg Brandle78fbcc2008-07-05 10:13:36 +00004664- Issue #2663: add filtering capability to shutil.copytree().

Nick Coghlanc060b0e2008-07-02 13:09:19 +00004677- Issue #3190: Pydoc now hides the automatic module attribute __package__ (the
4678 handling is now the same as that of other special attributes like __name__).
4679
Brett Cannon8bb8fa52008-07-02 01:57:08 +00004680- Issue #2885 (partial): The urllib.urlopen() function has been deprecated for

5136 and ``formatwarning()`` gain an optional 'line' argument which is
5137 not called by default for backwards-compatibility reasons. Setting
5138 ``warnings.showwarning()`` to an implementation that lacks support
5139 for the ``line`` argument will raise a DeprecationWarning.

Georg Brandl3ee81df2008-05-17 18:14:43 +00005202- Issue #2550: The approach used by client/server code for obtaining
5203 ports to listen on in network-oriented tests has been refined in an
5204 effort to facilitate running multiple instances of the entire
5205 regression test suite in parallel without issue.
5206 test_support.bind_port() has been fixed such that it will always
5207 return a unique port -- which wasn't always the case with the
5208 previous implementation, especially if socket options had been set
5209 that affected address reuse (i.e. SO_REUSEADDR, SO_REUSEPORT). The
5210 new implementation of bind_port() will actually raise an exception
5211 if it is passed an AF_INET/SOCK_STREAM socket with either the
5212 SO_REUSEADDR or SO_REUSEPORT socket option set. Furthermore, if
5213 available, bind_port() will set the SO_EXCLUSIVEADDRUSE option on
5214 the socket it's been passed. This currently only applies to
5215 Windows. This option prevents any other sockets from binding to the
5216 host/port we've bound to, thus removing the possibility of the
5217 'non-deterministic' behaviour, as Microsoft puts it, that occurs
5218 when a second SOCK_STREAM socket binds and accepts to a host/port
5219 that's already been bound by another socket. The optional preferred
5220 port parameter to bind_port() has been removed. Under no
5221 circumstances should tests be hard coding ports!
5222
5223 test_support.find_unused_port() has also been introduced, which will
5224 pass a temporary socket object to bind_port() in order to obtain an
5225 unused port. The temporary socket object is then closed and
5226 deleted, and the port is returned. This method should only be used
5227 for obtaining an unused port in order to pass to an external program
5228 (i.e. the -accept [port] argument to openssl's s_server mode) or as
5229 a parameter to a server-oriented class that doesn't give you direct
5230 access to the underlying socket used.
5231
5232 Finally, test_support.HOST has been introduced, which should be used
5233 for the host argument of any relevant socket calls (i.e. bind and
5234 connect).
Trent Nelsone41b0062008-04-08 23:47:30 +00005235
5236 The following tests were updated to following the new conventions:
Georg Brandl3ee81df2008-05-17 18:14:43 +00005237 test_socket, test_smtplib, test_asyncore, test_ssl, test_httplib,
Trent Nelsone41b0062008-04-08 23:47:30 +00005238 test_poplib, test_ftplib, test_telnetlib, test_socketserver,
5239 test_asynchat and test_socket_ssl.
5240
Georg Brandl3ee81df2008-05-17 18:14:43 +00005241 It is now possible for multiple instances of the regression test
5242 suite to run in parallel without issue.

Eric Smitha73fbe72008-02-23 03:09:44 +00005521- Added the future_builtins module, which contains hex() and oct().
5522 These are the PEP 3127 version of these functions, designed to be
5523 compatible with the hex() and oct() builtins from Python 3.0. They
5524 differ slightly in their output formats from the existing, unchanged
5525 Python 2.6 builtins. The expected usage of the future_builtins
5526 module is:
5527 from future_builtins import hex, oct
5528
Eric Smith7ef40bf2008-02-20 23:34:22 +00005529- Issue #1600: Modifed PyOS_ascii_formatd to use at most 2 digit
5530 exponents for exponents with absolute value < 100. Follows C99
5531 standard. This is a change on Windows, which would use 3 digits.
5532 Also, added 'n' to the formats that PyOS_ascii_formatd understands,
5533 so that any alterations it does to the resulting string will be
5534 available in stringlib/formatter.h (for float.__format__).
5535
Eric Smith5a3c1352008-02-19 13:21:56 +00005536- Implemented PEP 3101, Advanced String Formatting. This adds a new
5537 builtin format(); a format() method for str and unicode; a
5538 __format__() method to object, str, unicode, int, long, float, and
5539 datetime; the class string.Formatter; and the C API
5540 PyObject_Format().
5541
Georg Brandl3ee81df2008-05-17 18:14:43 +00005542- Fixed several potential crashes, all caused by specially crafted
5543 __del__ methods exploiting objects in temporarily inconsistent
5544 state.

5555 memory to the OS earlier.
Christian Heimes3b718a72008-02-14 12:47:33 +00005556
Georg Brandl3ee81df2008-05-17 18:14:43 +00005557- Issue #2045: Fix an infinite recursion triggered when printing a
5558 subclass of collections.defaultdict, if its default_factory is set
5559 to a bound method.

5570
Georg Brandl3ee81df2008-05-17 18:14:43 +00005571- Issue #1983: Fixed return type of fork(), fork1() and forkpty()

5573 returns pi_t.

Georg Brandl3ee81df2008-05-17 18:14:43 +00005587- Patch #1473257: generator objects gain a gi_code attribute. This is
5588 the same object as the func_code attribute of the function that
5589 produced the generator.
Georg Brandl0cdf9a32008-01-26 14:14:20 +00005590
Georg Brandl3ee81df2008-05-17 18:14:43 +00005591- Issue #1920: "while 0" statements were completely removed by the
5592 compiler, even in the presence of an "else" clause, which is
5593 supposed to be run when the condition is false. Now the compiler
5594 correctly emits bytecode for the "else" suite.
Amaury Forgeot d'Arc31eaafe2008-01-24 22:59:25 +00005595

Georg Brandl3ee81df2008-05-17 18:14:43 +00005619- Patch #1816: Added sys.flags structseq. It exposes the status of
5620 most command line arguments and PYTHON* environment variables.
Christian Heimesf31b69f2008-01-14 03:42:48 +00005621
Georg Brandl3ee81df2008-05-17 18:14:43 +00005622- Objects/structseq.c: Implemented new structseq representation. The
5623 patch makes structseqs (e.g. the return value of os.stat) more
5624 readable.
Christian Heimes9c201962008-01-14 03:33:52 +00005625
Georg Brandl3ee81df2008-05-17 18:14:43 +00005626- Patch #1700288: added a type attribute cache that caches method
5627 accesses, resulting in speedups in heavily object-oriented code.
Amaury Forgeot d'Arce4c270c2008-01-14 00:29:41 +00005628
Neal Norwitz3fc15b82008-01-10 05:42:58 +00005629- Bug #1776: __import__() no longer accepts filenames on any platform.
5630 The first parameter to __import__() must be a valid module name.
Christian Heimes3403f152008-01-09 19:56:33 +00005631
Georg Brandlaed6c662008-01-07 17:25:53 +00005632- Patch #1668: renamed THREADDEBUG envvar to PYTHONTHREADDEBUG.
5633
Georg Brandl3ee81df2008-05-17 18:14:43 +00005634- Patch #602345: Add -B command line option, PYTHONDONTWRITEBYTECODE
5635 envvar and sys.dont_write_bytecode attribute. All these can be set
5636 to forbid Python to attempt to write compiled bytecode files.
Georg Brandl2da0fce2008-01-07 17:09:35 +00005637
Georg Brandl3ee81df2008-05-17 18:14:43 +00005638- Improve some exception messages when Windows fails to load an
5639 extension module. Now we get for example '%1 is not a valid Win32
5640 application' instead of 'error code 193'.
Amaury Forgeot d'Arce0b76952008-01-04 02:04:15 +00005641
Georg Brandl3ee81df2008-05-17 18:14:43 +00005642- Bug #1481296: Fixed long(float('nan')) != 0L.
Christian Heimes8267d1d2008-01-04 00:37:34 +00005643
Georg Brandl3ee81df2008-05-17 18:14:43 +00005644- Issue #1640: Added math.isinf(x), math.isnan(x) and math.copysign(x,
5645 y) functions.
Christian Heimese2ca4242008-01-03 20:23:15 +00005646
Christian Heimes0a8143f2007-12-18 23:22:54 +00005647- Issue #1635: Platform independent creation and representation of NaN
Georg Brandl3ee81df2008-05-17 18:14:43 +00005648 and INF. float("nan"), float("inf") and float("-inf") now work on
5649 every platform with IEEE 754 semantics.
Christian Heimes0a8143f2007-12-18 23:22:54 +00005650
Georg Brandl3ee81df2008-05-17 18:14:43 +00005651- Compiler now generates simpler and faster code for dictionary
5652 literals. The oparg for BUILD_MAP now indicates an estimated
5653 dictionary size. There is a new opcode, STORE_MAP, for adding
5654 entries to the dictionary.
Raymond Hettingerfd7ed402007-12-18 21:24:09 +00005655
Georg Brandl3ee81df2008-05-17 18:14:43 +00005656- Issue #1638: %zd configure test fails on Linux.
Christian Heimesdb3d6cb2007-12-16 21:39:43 +00005657
Georg Brandl3ee81df2008-05-17 18:14:43 +00005658- Issue #1620: New property decorator syntax was modifying the
5659 decorator in place instead of creating a new decorator object.
Christian Heimes90e10e72007-12-14 02:35:23 +00005660
Georg Brandl3ee81df2008-05-17 18:14:43 +00005661- Issue #1538: Avoid copying string in split/rsplit if the split char
5662 is not found.
Skip Montanaro26015492007-12-08 15:33:24 +00005663
Andrew M. Kuchling395fe442007-12-05 13:27:20 +00005664- Issue #1553: An erroneous __length_hint__ can make list() raise a
Christian Heimes7cc1c6f2007-12-05 12:52:34 +00005665 SystemError.
5666
Nick Coghlanef01d822007-12-03 12:55:17 +00005667- PEP 366: Allow explicit relative imports when executing modules
5668 inside packages with the -m switch via a new module level
5669 __package__ attribute.
5670
Georg Brandl3ee81df2008-05-17 18:14:43 +00005671- Issue #1402: Fix a crash on exit, when another thread is still
5672 running, and if the deallocation of its frames somehow calls the
5673 PyGILState_Ensure() / PyGILState_Release() functions.
Amaury Forgeot d'Arcbe49a902007-11-30 20:37:22 +00005674

Amaury Forgeot d'Arcce7d10c2007-11-24 13:44:17 +00005678 attribute of an empty cell object.
5679
Georg Brandl3ee81df2008-05-17 18:14:43 +00005680- Issue #1460: The utf-7 incremental decoder did not accept truncated
5681 input. It now correctly saves its state between chunks of data.
Amaury Forgeot d'Arcf57375a2007-11-21 01:38:26 +00005682
Georg Brandl3ee81df2008-05-17 18:14:43 +00005683- Patch #1739468: Directories and zipfiles containing a __main__.py
5684 file can now be directly executed by passing their name to the
5685 interpreter. The directory/zipfile is automatically inserted as the
5686 first entry in sys.path.
Nick Coghlan327a39b2007-11-18 11:56:28 +00005687
Georg Brandl3ee81df2008-05-17 18:14:43 +00005688- Issue #1265: Fix a problem with sys.settrace, if the tracing
5689 function uses a generator expression when at the same time the
5690 executed code is closing a paused generator.
Amaury Forgeot d'Arc0d75f092007-11-13 21:54:28 +00005691
Raymond Hettinger1760c8a2007-11-08 02:52:43 +00005692- sets and frozensets now have an isdisjoint() method.
5693
Raymond Hettinger3f8caa32007-10-24 01:28:33 +00005694- optimize the performance of builtin.sum().
5695
Neal Norwitz44f326e2007-10-05 05:29:17 +00005696- Fix warnings found by the new version of the Coverity checker.
5697
Georg Brandl21e99f42010-03-07 15:23:59 +00005698- The enumerate() built-in function is no longer bounded to sequences
Georg Brandl3ee81df2008-05-17 18:14:43 +00005699 smaller than LONG_MAX. Formerly, it raised an OverflowError. Now,
5700 automatically shifts from ints to longs.
Raymond Hettinger8f669372007-10-03 21:18:11 +00005701
Georg Brandl3ee81df2008-05-17 18:14:43 +00005702- Issue #1686386: Tuple's tp_repr did not take into account the
5703 possibility of having a self-referential tuple, which is possible
5704 from C code. Nor did object's tp_str consider that a type's tp_str
5705 could do something that could lead to an inifinite recursion.
5706 Py_ReprEnter() and Py_EnterRecursiveCall(), respectively, fixed the
5707 issues.
Brett Cannon0b14f242007-09-30 19:45:10 +00005708
Georg Brandl3ee81df2008-05-17 18:14:43 +00005709- Issue #1164: It was possible to trigger deadlock when using the
5710 'print' statement to write to a file since the GIL was not released
5711 as needed. Now PyObject_Print() does the right thing along with
5712 various tp_print implementations of the built-in types and those in
5713 the collections module.
Brett Cannon01531592007-09-17 03:28:34 +00005714
Georg Brandl3ee81df2008-05-17 18:14:43 +00005715- Issue #1147: Exceptions were directly allowing string exceptions in
5716 their throw() method even though string exceptions no longer
5717 allowed.
Brett Cannon4c20bc42007-09-11 21:02:28 +00005718
Georg Brandl3ee81df2008-05-17 18:14:43 +00005719- Issue #1096: Prevent a segfault from getting the repr of a very
5720 deeply nested list by using the recursion counter.
Brett Cannona0c05512007-09-10 21:38:27 +00005721
Brett Cannon1e534b52007-09-07 04:18:30 +00005722- Issue #1202533: Fix infinite recursion calls triggered by calls to
Georg Brandl3ee81df2008-05-17 18:14:43 +00005723 PyObject_Call() never calling back out to Python code to trigger
5724 recursion depth updates/checks. Required the creation of a static
5725 RuntimeError instance in case normalizing an exception put the
5726 recursion check value past its limit. Fixes crashers
5727 infinite_rec_(1|2|4|5).py.
Brett Cannon1e534b52007-09-07 04:18:30 +00005728
Georg Brandl3ee81df2008-05-17 18:14:43 +00005729- Patch #1031213: Decode source line in SyntaxErrors back to its

5733 with %G.
5734
Georg Brandl3ee81df2008-05-17 18:14:43 +00005735- Prevent expandtabs() on string and unicode objects from causing a
5736 segfault when a large width is passed on 32-bit platforms.
Neal Norwitz7dbd2a32007-06-09 03:36:34 +00005737

Georg Brandla5ea6892007-06-01 11:33:33 +00005741
Neal Norwitz0ac60192007-05-27 04:08:54 +00005742- Add new attribute names for function objects. All the func_* become
Georg Brandl3ee81df2008-05-17 18:14:43 +00005743 __*__ attributes. (Some already existed, e.g., __doc__ and
5744 __name__.)
Neal Norwitz0ac60192007-05-27 04:08:54 +00005745
Neal Norwitz8b2bfbc2007-05-23 06:35:32 +00005746- Add -3 option to the interpreter to warn about features that are
5747 deprecated and will be changed/removed in Python 3.0.
5748
Georg Brandl2134e752007-05-21 20:34:16 +00005749- Patch #1686487: you can now pass any mapping after '**' in function
5750 calls.
5751
Collin Winter62903052007-05-18 23:11:24 +00005752- except clauses may now be spelled either "except E, target:" or
Georg Brandl3ee81df2008-05-17 18:14:43 +00005753 "except E as target:". This is to provide forwards compatibility
5754 with Python 3.0.
Collin Winter62903052007-05-18 23:11:24 +00005755
Brett Cannon229cee22007-05-05 01:34:02 +00005756- Deprecate BaseException.message as per PEP 352.
5757
Georg Brandl3ee81df2008-05-17 18:14:43 +00005758- Issue #1303614: don't expose object's __dict__ when the dict is
Georg Brandl21e99f42010-03-07 15:23:59 +00005759 inherited from a built-in base.
Armin Rigo9790a272007-05-02 19:23:31 +00005760
Vinay Sajip8549ce32007-05-06 17:53:37 +00005761- When __slots__ are set to a unicode string, make it work the same as
Neal Norwitzcbd9ee62007-04-14 05:25:50 +00005762 setting a plain string, ie don't expand to single letter identifiers.
5763
Raymond Hettinger13936692007-04-11 18:40:58 +00005764- Request #1191699: Slices can now be pickled.
5765
Raymond Hettinger4db5fe92007-04-12 04:10:00 +00005766- Request #1193128: str.translate() now allows a None argument for
5767 translations that only remove characters without re-mapping the
5768 remaining characters.
5769
Georg Brandl5cb76c12007-03-21 09:00:39 +00005770- Patch #1682205: a TypeError while unpacking an iterable is no longer
5771 masked by a generic one with the message "unpack non-sequence".
5772
Neal Norwitzaa754b72007-03-21 06:39:48 +00005773- Remove unused file Python/fmod.c.
5774
Guido van Rossum143b5642007-03-23 04:58:42 +00005775- Bug #1683368: The object.__init__() and object.__new__() methods are
5776 now stricter in rejecting excess arguments. The only time when
5777 either allows excess arguments is when it is not overridden and the
5778 other one is. For backwards compatibility, when both are
5779 overridden, it is a deprecation warning (for now; maybe a Py3k
Guido van Rossum234b1ff2007-03-23 19:39:01 +00005780 warning later). Also, type.__init__() insists on the same signature
5781 as supported by type.__new__().
Guido van Rossum143b5642007-03-23 04:58:42 +00005782
Georg Brandl3ee81df2008-05-17 18:14:43 +00005783- Patch #1675423: PyComplex_AsCComplex() now tries to convert an
5784 object to complex using its __complex__() method before falling back
5785 to the __float__() method. Therefore, the functions in the cmath
5786 module now can operate on objects that define a __complex__()
5787 method.
Georg Brandl2b869942007-03-17 16:08:45 +00005788
Georg Brandl3ee81df2008-05-17 18:14:43 +00005789- Patch #1623563: allow __class__ assignment for classes with
5790 __slots__. The old and the new class are still required to have the
5791 same slot names.
Žiga Seilnacht6f2d09c2007-03-16 11:59:38 +00005792
Georg Brandl3ee81df2008-05-17 18:14:43 +00005793- Patch #1642547: Fix an error/crash when encountering syntax errors
5794 in complex if statements.
Collin Winter77c67bd2007-03-16 04:11:30 +00005795
Georg Brandl3ee81df2008-05-17 18:14:43 +00005796- Patch #1462488: Python no longer segfaults when
5797 ``object.__reduce_ex__()`` is called with an object that is faking
5798 its type.
Žiga Seilnacht20f43d32007-03-15 11:44:55 +00005799
Georg Brandl3ee81df2008-05-17 18:14:43 +00005800- Patch #1680015: Don't modify __slots__ tuple if it contains an

Georg Brandl5240d742007-03-13 20:46:32 +00005803- Patch #1444529: the builtin compile() now accepts keyword arguments.
5804
Georg Brandl7b9c5552007-03-12 14:30:05 +00005805- Bug #1678647: write a newline after printing an exception in any
5806 case, even when converting the value to a string failed.
5807
Georg Brandl871f1bc2007-03-12 13:17:36 +00005808- The dir() function has been extended to call the __dir__() method on
Georg Brandl3ee81df2008-05-17 18:14:43 +00005809 its argument, if it exists. If not, it will work like before. This
5810 allows customizing the output of dir() in the presence of a
5811 __getattr__().
Georg Brandl871f1bc2007-03-12 13:17:36 +00005812
Collin Winter276887b2007-03-12 16:11:39 +00005813- Patch #922167: Python no longer segfaults when faced with infinitely
5814 self-recursive reload() calls (as reported by bug #742342).
5815
Georg Brandl3ee81df2008-05-17 18:14:43 +00005816- Patch #1675981: remove unreachable code from ``type.__new__()``

Georg Brandl3ee81df2008-05-17 18:14:43 +00005819- Patch #1491866: change the complex() constructor to allow
5820 parthensized forms. This means complex(repr(x)) now works instead of
5821 raising a ValueError.
Collin Wintere38051d2007-03-09 20:33:07 +00005822
Georg Brandlaa2321b2007-03-07 00:40:28 +00005823- Patch #703779: unset __file__ in __main__ after running a file. This
Georg Brandl3ee81df2008-05-17 18:14:43 +00005824 makes the filenames the warning module prints much more sensible
5825 when a PYTHONSTARTUP file is used.
Georg Brandlaa2321b2007-03-07 00:40:28 +00005826
Georg Brandl49aafc92007-03-07 00:34:46 +00005827- Variant of patch #697613: don't exit the interpreter on a SystemExit
5828 exception if the -i command line option or PYTHONINSPECT environment
Georg Brandl3ee81df2008-05-17 18:14:43 +00005829 variable is given, but break into the interactive interpreter just
5830 like on other exceptions or normal program exit.

Georg Brandl3ee81df2008-05-17 18:14:43 +00005835- Bug #1674503: close the file opened by execfile() in an error
5836 condition.
Georg Brandl098cd692007-03-06 12:17:50 +00005837
Georg Brandl0fca97a2007-03-05 22:28:08 +00005838- Patch #1674228: when assigning a slice (old-style), check for the
5839 sq_ass_slice instead of the sq_slice slot.
5840
Georg Brandl3ee81df2008-05-17 18:14:43 +00005841- When printing an unraisable error, don't print exceptions. before
5842 the name. This duplicates the behavior whening normally printing
5843 exceptions.
Neal Norwitz88516a62007-02-26 22:41:45 +00005844
Georg Brandl3ee81df2008-05-17 18:14:43 +00005845- Bug #1653736: Properly discard third argument to

Georg Brandl3ee81df2008-05-17 18:14:43 +00005851- Bug #1377858: Fix the segfaulting of the interpreter when an object
5852 created a weakref on itself during a __del__ call for new-style
5853 classes (classic classes still have the bug).

Facundo Batistab6a5c9d2007-03-29 18:22:35 +00006345- Added a timeout parameter to the constructor of other protocols
6346 (telnetlib, ftplib, smtplib and poplib). This is second part of the
6347 work started with create_connection() and timeout in httplib, and
6348 closes patch #723312.
6349
Vinay Sajip8549ce32007-05-06 17:53:37 +00006350- Patch #1676823: Added create_connection() to socket.py, which may be
6351 called with a timeout, and use it from httplib (whose HTTPConnection
Facundo Batista70f996b2007-05-21 17:32:32 +00006352 and HTTPSConnection now accept an optional timeout).
Facundo Batista07c78be2007-03-23 18:54:07 +00006353

6374
Georg Brandlf66b6032007-03-14 08:27:52 +00006375- Bug #767111: fix long-standing bug in urllib which caused an
Georg Brandl3ee81df2008-05-17 18:14:43 +00006376 AttributeError instead of an IOError when the server's response
6377 didn't contain a valid HTTP status line.
Georg Brandlf66b6032007-03-14 08:27:52 +00006378
Georg Brandl3ee81df2008-05-17 18:14:43 +00006379- Patch #957650: "%var%" environment variable references are now
6380 properly expanded in ntpath.expandvars(), also "~user" home

Georg Brandl3ee81df2008-05-17 18:14:43 +00006383- Patch #1429539: pdb now correctly initializes the __main__ module
6384 for the debugged script, which means that imports from __main__ work
Georg Brandlb6ae6aa2007-03-13 21:58:44 +00006385 correctly now.
6386
Georg Brandlbad6f192007-03-13 21:32:56 +00006387- The nonobvious commands.getstatus() function is now deprecated.

6393
Georg Brandl3ee81df2008-05-17 18:14:43 +00006394- Patch #1530482: add pydoc.render_doc() which returns the
6395 documentation for a thing instead of paging it to stdout, which

6404 parameter which can be set to False to prevent the default
6405 delete-on-close behavior.
Georg Brandl35ef9c12007-03-13 18:31:49 +00006406
Georg Brandl9e6b4702007-03-13 18:15:41 +00006407- Patch #1581073: add a flag to textwrap that prevents the dropping of
6408 whitespace while wrapping.
6409
Georg Brandl92a6bae2007-03-13 17:43:32 +00006410- Patch #1603688: ConfigParser.SafeConfigParser now checks values that
Georg Brandl3ee81df2008-05-17 18:14:43 +00006411 are set for invalid interpolation sequences that would lead to
6412 errors on reading back those values.
Georg Brandl92a6bae2007-03-13 17:43:32 +00006413

Georg Brandl3ee81df2008-05-17 18:14:43 +00006428 field names in its exception message if you try to write a record
6429 with a dictionary containing fields not in the CSV field names list.

6455 returned string up to the first NUL character.
6456

6466
Georg Brandl3ee81df2008-05-17 18:14:43 +00006467- unittest now verifies more of its assumptions. In particular,
6468 TestCase and TestSuite subclasses (not instances) are no longer
6469 accepted in TestSuite.addTest(). This should cause no
6470 incompatibility since it never made sense with ordinary subclasses
6471 -- the failure just occurred later, with a more cumbersome
6472 exception.
Georg Brandl9caadf82007-03-08 18:37:31 +00006473

6481 given a unicode argument and os.listdir() returns unicode filenames.
6482
Georg Brandl3ee81df2008-05-17 18:14:43 +00006483- Patch #1673619: setup.py identifies extension modules it doesn't

Georg Brandl3ee81df2008-05-17 18:14:43 +00006861 time so that opening a database previously created with the DB_DUP
6862 or DB_DUPSORT flag set will keep the proper behavior on subsequent
6863 opens. Specifically: dictionary assignment to a DB object will
6864 replace all values for a given key when the database allows
6865 duplicate values. DB users should use DB.put(k, v) when they want
6866 to store duplicates; not DB[k] = v.

6873 characters with ASCII value less than 32. Also, it correctly quotes
6874 dots only if they occur on a single line, as opposed to the previous
6875 behavior of quoting dots if they are the second character of any
6876 line.
Georg Brandl4aef7272007-03-13 22:49:43 +00006877
