354-----------------
355
Ezio Melottiab2eb0e2010-06-05 19:21:32 +0000356- Issue #8271: during the decoding of an invalid UTF-8 byte sequence, only the
357 start byte and the continuation byte(s) are now considered invalid, instead
358 of the number of bytes specified by the start byte.
359 E.g.: '\xf1\x80AB'.decode('utf-8', 'replace') now returns u'\ufffdAB' and
360 replaces with U+FFFD only the start byte ('\xf1') and the continuation byte
361 ('\x80') even if '\xf1' is the start byte of a 4-bytes sequence.
362 Previous versions returned a single u'\ufffd'.
363
Mark Dickinson23f0d6b2010-06-05 11:52:24 +0000364- Issue #8627: Remove bogus "Overriding __cmp__ blocks inheritance of
Mark Dickinsone4b83e02010-06-05 12:14:43 +0000365 __hash__ in 3.x" warning. Also fix "XXX undetected error" that
366 arises from the "Overriding __eq__ blocks inheritance ..." warning
367 when turned into an exception: in this case the exception simply
368 gets ignored.

Mark Dickinson4ca7c3c2010-05-30 13:18:10 +0000370- Issue #8748: Fix two issues with comparisons between complex and integer
371 objects. (1) The comparison could incorrectly return True in some cases
372 (2**53+1 == complex(2**53) == 2**53), breaking transivity of equality.
373 (2) The comparison raised an OverflowError for large integers, leading
374 to unpredictable exceptions when combining integers and complex objects
375 in sets or dicts.
376
Mark Dickinson81336372010-05-30 12:12:25 +0000377- Issue #5211: Implicit coercion for the complex type is now completely
378 removed. (Coercion for arithmetic operations was already removed in 2.7
379 alpha 4, but coercion for rich comparisons was accidentally left in.)
380
Victor Stinnerc49dfcc2010-05-25 22:30:32 +0000381- Issue #3798: Write sys.exit() message to sys.stderr to use stderr encoding

383
Georg Brandlfee0f442010-05-22 21:26:21 +0000384- Issue #7902: When using explicit relative import syntax, don't try implicit

743
Benjamin Peterson3a1dfa22010-04-06 21:50:00 +0000744- Issue #8329: Don't return the same lists from select.select when no fds are
745 changed.

758 with a non-empty format string. This is an effort to future-proof user
759 code. If a derived class does not currently implement __format__ but later
760 adds its own __format__, it would most likely break user code that had
761 supplied a format string. This will be changed to a DeprecationWaring in
762 Python 3.3 and it will be an error in Python 3.4.

Georg Brandlfee0f442010-05-22 21:26:21 +0000812- Issue #7279: Comparisons involving a Decimal signaling NaN now signal
813 InvalidOperation instead of returning False. (Comparisons involving a quiet
814 NaN are unchanged.) Also, Decimal quiet NaNs are now hashable; Decimal
815 signaling NaNs remain unhashable.

Georg Brandlfee0f442010-05-22 21:26:21 +0000817- Issue #2531: Comparison operations between floats and Decimal instances now
818 return a result based on the numeric values of the operands; previously they
819 returned an arbitrary result based on the relative ordering of id(float) and

Georg Brandlfee0f442010-05-22 21:26:21 +0000823 argument `-` which tells it to read files to compile from stdin. Each line is

Georg Brandlfee0f442010-05-22 21:26:21 +0000834- Comparisons using one of <, <=, >, >= between a complex instance and a
835 Fractions instance now raise TypeError instead of returning True/False. This
836 makes Fraction <=> complex comparisons consistent with int <=> complex, float

Georg Brandlba83f822010-03-14 09:50:54 +00001244 specified, rather than fall through to AF_PACKET (in the ``socket`` module).

Georg Brandlba83f822010-03-14 09:50:54 +00001251 file position when calling `truncate()`. It would previously change the file
1252 position to the given argument, which goes against the tradition of
Antoine Pitrouf3fa0742010-01-31 22:26:04 +00001253 ftruncate() and other truncation APIs. Patch by Pascal Chambon.
1254

1256 class used to represent files stored inside an archive. The new
1257 implementation is significantly faster and can be wrapped in a
1258 ``io.BufferedReader`` object for more speedups. It also solves an issue
1259 where interleaved calls to ``read()`` and ``readline()`` give wrong results.

1272 encoded string for them. This ensures that the upload and register commands
1273 send the correct values to PyPI without any error.

1349
Georg Brandlba83f822010-03-14 09:50:54 +00001350- The ``__complex__()`` method is now looked up on the class of instances to
1351 make it consistent with other special methods.
Benjamin Petersonecdae192010-01-04 00:43:01 +00001352
Antoine Pitrou5b7139a2010-01-02 21:12:58 +00001353- Issue #7462: Implement the stringlib fast search algorithm for the `rfind`,

1355
Mark Dickinson1b34d252010-01-01 17:27:30 +00001356- Issue #5080: A number of functions and methods previously produced a
Georg Brandlba83f822010-03-14 09:50:54 +00001357 DeprecationWarning when passed a float argument where an integer was expected.
1358 These functions and methods now raise TypeError instead. The majority of the
1359 effects of this change are in the extension modules, but some core functions
1360 and methods are affected: notably the 'chr', 'range' and 'xrange' builtins,
1361 and many unicode/str methods.

1373
Georg Brandlba83f822010-03-14 09:50:54 +00001374- Issue #1811: Improve accuracy and cross-platform consistency for true division
1375 of integers: the result of a/b is now correctly rounded for ints a and b (at
1376 least on IEEE 754 platforms), and in particular does not depend on the
1377 internal representation of a long.

Ronald Oussoren92919a62009-12-24 13:30:58 +00001384 executables on OSX.
1385
Georg Brandlba83f822010-03-14 09:50:54 +00001386 These executables now work properly with the arch(1) command: ``arch -ppc
1387 python`` will start a universal binary version of python in PPC mode (unlike

Georg Brandlba83f822010-03-14 09:50:54 +00001411 renaming of `cPickle` to `pickle`. The warning was annoying since there's no

Georg Brandlba83f822010-03-14 09:50:54 +00001551- Issue #7117: On almost all platforms: float-to-string and string-to-float
1552 conversions within Python are now correctly rounded. Places these conversions
1553 occur include: str for floats and complex numbers; the float and complex
1554 constructors; old-style and new-style numeric formatting; serialization and
1555 deserialization of floats and complex numbers using marshal, pickle and json;
1556 parsing of float and imaginary literals in Python code; Decimal-to-float
1557 conversion.
Mark Dickinsonb678de82009-11-19 18:41:49 +00001558
Georg Brandlba83f822010-03-14 09:50:54 +00001559 The conversions use a Python-adapted version of David Gay's well-known dtoa.c,
1560 providing correctly-rounded strtod and dtoa C functions. This code is
1561 supported on Windows, and on Unix-like platforms using gcc, icc or suncc as
1562 the C compiler. There may be a small number of platforms on which correct
1563 operation of this code cannot be guaranteed, so the code is not used: notably,
1564 this applies to platforms where the C double format is not IEEE 754 binary64,
1565 and to platforms on x86 hardware where the x87 FPU is set to 64-bit precision
1566 and Python's configure script is unable to determine how to change the FPU
1567 precision. On these platforms conversions use the platform strtod and dtoa,
1568 as before.

Georg Brandlba83f822010-03-14 09:50:54 +00001570- Issue #7117: Backport round implementation from Python 3.x. ``round()`` now
1571 uses the correctly-rounded string <-> float conversions described above (when
1572 available), and so produces correctly rounded results that will display nicely
1573 under the float repr. There are two related small changes: (1) round now
1574 accepts any class with an ``__index__()`` method for its second argument (but
1575 no longer accepts floats for the second argument), and (2) an excessively
1576 large second integer argument (e.g., ``round(1.234, 10**100)``) no longer
1577 raises an exception.

3159 'b', 'B', 'h', 'H', 'i', 'l', '*b', '*h' ,'*i', '*l', and an x with a
3160 __long__ method could be packed by 'q', 'Q', '*q', '*Q'; for x with
3161 neither __int__ nor __long__, TypeError used to be raised (with a

Amaury Forgeot d'Arc05e34492008-09-10 22:04:45 +00003360- Issue #3743: In a few places, PY_FORMAT_SIZE_T was incorrectly used with
3361 PyString_FromFormat or PyErr_Format to display size_t values. The macro
3362 PY_FORMAT_SIZE_T is designed to select the correct format for the OS
3363 ``printf`` function, whereas PyString_FromFormat has an independent
3364 implementation and uses "%zd" on all platforms for size_t values.

Brett Cannon1eaf0742008-09-02 01:25:16 +00003461 warnings.catch_warnings() along with some API cleanup. Expanding the tests
3462 for catch_warnings() also led to an improvement in the raising of a
3463 DeprecationWarning related to warnings.warn_explicit().

Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00003529What's New in Python 2.6 beta 3?
3530================================
3531
Barry Warsaw07a4a382008-08-21 01:15:08 +00003532*Release date: 20-Aug-2008*
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00003533
3534Core and Builtins
3535-----------------
3536
Guido van Rossumf8402962008-08-20 15:01:50 +00003537- Issue #1878: Remove Py_TPFLAGS_HAVE_VERSION_TAG from
3538 Py_TPFLAGS_DEFAULT when not building the core. This means 3rd party
3539 extensions do not automatically benefit from the class attribute
3540 cache; they will have to explicitly add Py_TPFLAGS_HAVE_VERSION_TAG
3541 to their tp_flags field if they care. This is a backwards
3542 compatibility feature; in 3.0, all types will use the cache by
3543 default.
3544
Benjamin Petersonf647dc12008-08-20 01:27:30 +00003545- Keyword arguments can now follow starred arguments. (``f(a, *args,
3546 keyword=23)`` is now valid syntax.)
3547
Thomas Heller0ad5ae02008-08-19 19:25:04 +00003548- ctypes function pointers that are COM methods have a boolean True
3549 value again.
3550
Martin v. Löwisf91d46a2008-08-12 14:49:50 +00003551- Issue #3139: Make buffer-interface thread-safe wrt. PyArg_ParseTuple,
3552 by denying s# to parse objects that have a releasebuffer procedure,
3553 and introducing s*.
3554
Georg Brandl1e13ea92008-08-11 09:07:59 +00003555- Issue #3537: Fix an assertion failure when an empty but presized dict
3556 object was stored in the freelist.
3557
Mark Dickinsonb6467572008-08-04 21:30:09 +00003558- Issue #1481296: Make long(float('nan')) and int(float('nan')) raise
3559 ValueError consistently across platforms.
3560
Amaury Forgeot d'Arc39fd6722008-07-31 21:28:03 +00003561- Issue #3479: On platforms where sizeof(int) is smaller than sizeof(long)
3562 (64bit Unix, for example), unichr() would truncate its argument and return
3563 u'\x00' for unichr(2**32). Now it properly raises an OverflowError.
3564
Neal Norwitze7d8be82008-07-31 17:17:14 +00003565- Apply security patches from Apple.
3566
Amaury Forgeot d'Arc246daed2008-07-31 00:42:16 +00003567- Issue #2542: Now that issubclass() may call arbitrary code, ensure that
3568 PyErr_ExceptionMatches returns 0 when an exception occurs there.
3569
Antoine Pitrou92f82162008-07-25 22:22:08 +00003570- Issue #1819: function calls with several named parameters are now on
3571 average 35% faster (as measured by pybench).
3572
Amaury Forgeot d'Arce4921fe2008-07-21 22:00:38 +00003573- Issue #2378: An unexpected UnboundLocalError or NameError could appear when
3574 the python debugger steps into a class statement: the free variables (local
3575 variables defined in an outer scope) would be deleted from the outer scope.
3576
Gregory P. Smith0470bab2008-07-22 04:46:32 +00003577- Issue #2620: Overflow checking when allocating or reallocating memory
3578 was not always being done properly in some python types and extension
3579 modules. PyMem_MALLOC, PyMem_REALLOC, PyMem_NEW and PyMem_RESIZE have
3580 all been updated to perform better checks and places in the code that
3581 would previously leak memory on the error path when such an allocation
3582 failed have been fixed.

3585-------
3586
Hirokazu Yamamoto838c79f2008-08-20 13:14:07 +00003587- Issue #3612: Added some missing basic types in ctypes.wintypes.
3588
Benjamin Petersone977ad42008-08-20 01:42:01 +00003589- The methods ``is_in_tuple()``, ``is_vararg()``, and ``is_keywordarg()`` of
3590 symtable.Symbol have been deprecated for removal in 3.0 and the next release.
3591
Amaury Forgeot d'Arc351ffb82008-08-18 19:23:47 +00003592- Issue #2234: distutils failed for some versions of the cygwin compiler. The
3593 version reported by these tools does not necessarily follow the python
3594 version numbering scheme, so the module is less strict when parsing it.
3595
Nick Coghlanf70385a2008-08-18 12:42:46 +00003596- Issue #2235: Added Py3k warnings for types which will become unhashable
3597 under the stricter __hash__ inheritance rules in 3.0. Several types
3598 which did not meet the rules for hash invariants and were already
3599 unhashable in 3.0 have now been explicitly flagged as unhashable in
3600 2.6 as well (collections.Mapping, collections.Set, unittest.TestSuite,
3601 xml.dom.minidom.NamedNodeMap, numbers.Number, UserList.UserList)
3602
Brett Cannon88f801d2008-08-18 00:46:22 +00003603- Update __all__ for cookielib, csv, os, urllib2, and weakref to include things
3604 imported into the module but exposed as part of the module's API.
3605
Brett Cannon7b96f072008-08-18 00:41:11 +00003606- Remove an unneeded import of abc.ABCMeta from 'inspect'.
3607
Brett Cannon46225e72008-08-18 00:36:52 +00003608- Remove unneeded imports of 'sys' and 'warnings' from 'io'.

Brett Cannon25c9d6a2008-08-17 22:10:11 +00003610- Remove unneeded imports of 'warnings' from shelve, filecmp, and dummy_thread.
3611
Hirokazu Yamamoto41a81eb2008-08-17 13:10:46 +00003612- Issue #3575: Incremental decoder's decode function now takes bytearray
3613 by using 's*' instead of 't#'.
3614
Mark Dickinson3e4caeb2009-02-21 20:27:01 +00003615- Issue #2222: Fixed reference leak when occurred os.rename()
Hirokazu Yamamoto7f30a682008-08-17 09:46:56 +00003616 fails unicode conversion on 2nd parameter. (windows only)
3617
Georg Brandl222e2082010-08-01 22:27:39 +00003618- Issue #2464: urllib2 now supports a malformation in the URL received
Facundo Batista94f243a2008-08-17 03:38:39 +00003619 in a redirect.
3620
Brett Cannonabe423e2008-08-16 21:47:07 +00003621- Silence the DeprecationWarning raised when importing mimetools in
Brett Cannon721b1452008-08-16 22:00:27 +00003622 BaseHTTPServer, cgi (and rfc822), httplib.
Brett Cannonabe423e2008-08-16 21:47:07 +00003623
Facundo Batistaeb90b782008-08-16 14:44:07 +00003624- Issue #2776: fixed small issue when handling an URL with double slash
3625 after a 302 response in the case of not going through a proxy.
3626
Antoine Pitroub90a8be2008-08-15 21:03:21 +00003627- Issue #2676: in the email package, content-type parsing was hanging on
3628 pathological input because of quadratic or exponential behaviour of a
3629 regular expression.
3630
Antoine Pitrou11ec65d2008-08-14 21:04:30 +00003631- Issue #3476: binary buffered reading through the new "io" library is now
3632 thread-safe.
3633
Brett Cannonbf3157b2008-08-14 05:00:03 +00003634- Silence the DeprecationWarning of rfc822 when it is imported by mimetools
3635 since mimetools itself is deprecated. Because modules are cached, all
3636 subsequent imports of rfc822 will not raise a visible DeprecationWarning.
3637
Antoine Pitrou9fcd4b32008-08-11 17:21:36 +00003638- Issue #3134: shutil referenced undefined WindowsError symbol.
3639
Robert Schuppenies14646332008-08-10 11:01:53 +00003640- Issue #1342811: Fix leak in Tkinter.Menu.delete. Commands associated to
3641 menu entries were not deleted.
3642
Brett Cannon83e81842008-08-09 23:30:55 +00003643- Copied the implementation of reduce() to _functools.reduce() to have a
3644 version that did not raise a DeprecationWarning under -3.
3645
Antoine Pitrou76b8bee2008-08-09 17:27:23 +00003646- Issue #3205: When iterating over a BZ2File fails allocating memory, raise
3647 a MemoryError rather than silently stop the iteration.
3648
Guido van Rossum59ce9012008-08-09 14:55:34 +00003649- Issue #3487: sre "bytecode" validator. Passing invalid "re-bytecode"
3650 to _sre.compile() will now be rejected. This should not affect anybody
3651 since the re.compile() function never generates invalid re-bytecode.
3652
Skip Montanaroa032bf42008-08-08 22:52:51 +00003653- Issue #3436: Make csv.DictReader's fieldnames attribute a property so that
3654 upon first access it can be automatically initialized from the csv file if
3655 it wasn't initialized during instantiation.
3656
Brett Cannon3aa2a492008-08-06 22:28:09 +00003657- Issue #2338: Create imp.reload() to help with transitioning to Python 3.0 as
3658 the reload() built-in has been removed.
3659
Brett Cannon7e30b672008-08-04 21:52:25 +00003660- Changed code in the following modules/packages to remove warnings raised
Brett Cannonc1b76e42008-08-09 23:06:16 +00003661 while running under the ``-3`` flag: aifc, asynchat, asyncore, bdb, bsddb,

Antoine Pitroude781a42008-08-09 12:43:23 +00003672 asking for a specific length. This problem only affected files opened
3673 using the new "io" module, not the built-in open() function.
Benjamin Peterson01a24322008-07-28 23:35:27 +00003674

Antoine Pitrou5fdfa3e2008-07-25 19:42:26 +00003698- Issue #3394: zipfile.writestr sets external attributes when passed a
3699 file name rather than a ZipInfo instance, so files are extracted with

3701
Gregory P. Smitha36f8fe2008-08-04 00:13:29 +00003702- Issue #1857: subprocess.Popen.poll gained an additional _deadstate keyword

3716
Nick Coghlan2a0c2b12008-08-04 12:47:17 +00003717- Issue #643841: The language reference now provides more detailed
3718 coverage of the lookup process for special methods. The disclaimers

3724================================
3725
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00003726*Release date: 17-Jul-2008*

Raymond Hettingere3ae6552008-06-20 04:18:15 +00003728Core and Builtins
3729-----------------
3730
Georg Brandl3e483f62008-07-16 22:57:41 +00003731- Issue #3156: Fix inconsistent behavior of the bytearray type: all
3732 its methods now allow for items objects that can be converted to
3733 an integer using operator.index().
3734
Mark Dickinson64b7e502008-07-16 09:40:03 +00003735- Issue #3360: Fix incorrect parsing of '020000000000.0', which
3736 produced a ValueError instead of giving the correct float.
3737
Eric Smitha5fa5a22008-07-16 00:11:49 +00003738- Issue #3083: Add alternate (#) formatting for bin, oct, hex output
3739 for str.format(). This adds the prefix 0b, 0o, or 0x, respectively.
3740
Mark Dickinson7103aa42008-07-15 19:08:33 +00003741- Issue #3008: the float type has a new instance method 'float.hex'
3742 and a new class method 'float.fromhex' to convert floating-point
3743 numbers to and from hexadecimal strings, respectively.
3744
Nick Coghlan6d6bd442008-07-15 15:40:22 +00003745- Issue #2235: __hash__ is once again inherited by default. To allow
3746 collections.Hashable to remain meaningful in the presence of the
3747 default hash implementation (object.__hash__), it is now possible
3748 to explicit block inheritance of hash by setting __hash__=None at
3749 the Python level, or tp_hash=PyObject_HashNotImplemented at the C
3750 level.
3751
Nick Coghlanb028f502008-07-13 14:52:36 +00003752- Issue #3221: Issue a RuntimeWarning instead of raising SystemError if
3753 the parent module cannot be found while performing an absolute import.
3754 This means that an incorrectly defined __package__ attribute will
3755 now only prevent relative imports in that module rather than causing
3756 all imports from that module to fail.
3757
Nick Coghlan14ff9942008-07-08 14:21:42 +00003758- Issue #2517: Allow unicode messages in Exceptions again by correctly
3759 bypassing the instance dictionary when looking up __unicode__ on
3760 new-style classes.

3763 set to a custom object whose write() method happens to install
3764 another file in sys.stdout.
3765
Amaury Forgeot d'Arc1f40c8a2008-06-30 22:42:40 +00003766- Issue #3088: Corrected a race condition in classes derived from
3767 threading.local: the first member set by a thread could be saved in
3768 another thread's dictionary.
3769
Mark Dickinson1ec2fcd2008-06-20 14:53:43 +00003770- Issue #3004: Minor change to slice.indices(): the start and stop
3771 arguments are now treated identically, making the behaviour easier
3772 to describe and understand. For example, slice(None, -10,
3773 1).indices(9) now returns (0, 0, 1) instead of (0, -1, 1), and
3774 slice(None, 10, -1).indices(10) returns (9, 9, -1) instead of (9,
3775 10, -1).
3776
Georg Brandl278fc502008-07-19 12:46:12 +00003777- Issue #3219: Calling a function with repeated keyword arguments,
3778 f(a=2, a=23), would not cause a syntax error. This was a regression
3779 from 2.4 caused by the switch to the new compiler.
Benjamin Peterson175e4d92008-07-01 19:34:52 +00003780
Georg Brandl278fc502008-07-19 12:46:12 +00003781- Issue #2862: Make int and float freelist management consistent with
3782 other freelists. Changes their CompactFreeList apis into
3783 ClearFreeList apis and calls them via gc.collect().

Thomas Heller57adf222008-08-14 19:10:48 +00003788- Issue #3554: ctypes.string_at and ctypes.wstring_at did call Python
3789 api functions without holding the GIL, which could lead to a fatal
3790 error when they failed.
3791
Martin v. Löwisaabf4042008-08-02 07:20:25 +00003792- Issue #799428: Fix Tkinter.Misc._nametowidget to unwrap Tcl command objects.

3801 ForkingPickler.register() to resolve conflict with ctypes.
3802
Vinay Sajip51e65192008-07-18 09:01:10 +00003803- Issue #3090: Fixed ARCHFLAGS parsing on OS/X
Jesse Noller13e9d582008-07-16 14:32:36 +00003804
Thomas Heller880f5292008-07-15 19:39:38 +00003805- Issue #3313: Fixed a crash when a failed dlopen() call does not set
3806 a valid dlerror() message.

3814
Andrew M. Kuchlingcc3f2b12008-07-10 14:43:31 +00003815- Issue #3301: Bisect module behaved badly when lo was negative.
Raymond Hettinger3cd1e422008-07-10 14:03:19 +00003816
Amaury Forgeot d'Arc0f7cddc2008-07-06 21:34:39 +00003817- Issue #839496: SimpleHTTPServer used to open text files in text mode. This is
3818 both unnecessary (HTTP allows text content to be sent in several forms) and
Andrew M. Kuchlingcc3f2b12008-07-10 14:43:31 +00003819 wrong because the actual transmitted size could differ from the
Amaury Forgeot d'Arc0f7cddc2008-07-06 21:34:39 +00003820 content-length. The problem had been corrected in the 2.4 branch, but never
3821 merged into trunk.
3822
Georg Brandle78fbcc2008-07-05 10:13:36 +00003823- Issue #2663: add filtering capability to shutil.copytree().

Nick Coghlanc060b0e2008-07-02 13:09:19 +00003836- Issue #3190: Pydoc now hides the automatic module attribute __package__ (the
3837 handling is now the same as that of other special attributes like __name__).
3838
Brett Cannon8bb8fa52008-07-02 01:57:08 +00003839- Issue #2885 (partial): The urllib.urlopen() function has been deprecated for

4295 and ``formatwarning()`` gain an optional 'line' argument which is
4296 not called by default for backwards-compatibility reasons. Setting
4297 ``warnings.showwarning()`` to an implementation that lacks support
4298 for the ``line`` argument will raise a DeprecationWarning.

Georg Brandl3ee81df2008-05-17 18:14:43 +00004361- Issue #2550: The approach used by client/server code for obtaining
4362 ports to listen on in network-oriented tests has been refined in an
4363 effort to facilitate running multiple instances of the entire
4364 regression test suite in parallel without issue.
4365 test_support.bind_port() has been fixed such that it will always
4366 return a unique port -- which wasn't always the case with the
4367 previous implementation, especially if socket options had been set
4368 that affected address reuse (i.e. SO_REUSEADDR, SO_REUSEPORT). The
4369 new implementation of bind_port() will actually raise an exception
4370 if it is passed an AF_INET/SOCK_STREAM socket with either the
4371 SO_REUSEADDR or SO_REUSEPORT socket option set. Furthermore, if
4372 available, bind_port() will set the SO_EXCLUSIVEADDRUSE option on
4373 the socket it's been passed. This currently only applies to
4374 Windows. This option prevents any other sockets from binding to the
4375 host/port we've bound to, thus removing the possibility of the
4376 'non-deterministic' behaviour, as Microsoft puts it, that occurs
4377 when a second SOCK_STREAM socket binds and accepts to a host/port
4378 that's already been bound by another socket. The optional preferred
4379 port parameter to bind_port() has been removed. Under no
4380 circumstances should tests be hard coding ports!
4381
4382 test_support.find_unused_port() has also been introduced, which will
4383 pass a temporary socket object to bind_port() in order to obtain an
4384 unused port. The temporary socket object is then closed and
4385 deleted, and the port is returned. This method should only be used
4386 for obtaining an unused port in order to pass to an external program
4387 (i.e. the -accept [port] argument to openssl's s_server mode) or as
4388 a parameter to a server-oriented class that doesn't give you direct
4389 access to the underlying socket used.
4390
4391 Finally, test_support.HOST has been introduced, which should be used
4392 for the host argument of any relevant socket calls (i.e. bind and
4393 connect).
Trent Nelsone41b0062008-04-08 23:47:30 +00004394
4395 The following tests were updated to following the new conventions:
Georg Brandl3ee81df2008-05-17 18:14:43 +00004396 test_socket, test_smtplib, test_asyncore, test_ssl, test_httplib,
Trent Nelsone41b0062008-04-08 23:47:30 +00004397 test_poplib, test_ftplib, test_telnetlib, test_socketserver,
4398 test_asynchat and test_socket_ssl.
4399
Georg Brandl3ee81df2008-05-17 18:14:43 +00004400 It is now possible for multiple instances of the regression test
4401 suite to run in parallel without issue.

Eric Smitha73fbe72008-02-23 03:09:44 +00004680- Added the future_builtins module, which contains hex() and oct().
4681 These are the PEP 3127 version of these functions, designed to be
4682 compatible with the hex() and oct() builtins from Python 3.0. They
4683 differ slightly in their output formats from the existing, unchanged
4684 Python 2.6 builtins. The expected usage of the future_builtins
4685 module is:
4686 from future_builtins import hex, oct
4687
Eric Smith7ef40bf2008-02-20 23:34:22 +00004688- Issue #1600: Modifed PyOS_ascii_formatd to use at most 2 digit
4689 exponents for exponents with absolute value < 100. Follows C99
4690 standard. This is a change on Windows, which would use 3 digits.
4691 Also, added 'n' to the formats that PyOS_ascii_formatd understands,
4692 so that any alterations it does to the resulting string will be
4693 available in stringlib/formatter.h (for float.__format__).
4694
Eric Smith5a3c1352008-02-19 13:21:56 +00004695- Implemented PEP 3101, Advanced String Formatting. This adds a new
4696 builtin format(); a format() method for str and unicode; a
4697 __format__() method to object, str, unicode, int, long, float, and
4698 datetime; the class string.Formatter; and the C API
4699 PyObject_Format().
4700
Georg Brandl3ee81df2008-05-17 18:14:43 +00004701- Fixed several potential crashes, all caused by specially crafted
4702 __del__ methods exploiting objects in temporarily inconsistent
4703 state.

4714 memory to the OS earlier.
Christian Heimes3b718a72008-02-14 12:47:33 +00004715

Georg Brandl3ee81df2008-05-17 18:14:43 +00004746- Patch #1473257: generator objects gain a gi_code attribute. This is
4747 the same object as the func_code attribute of the function that
4748 produced the generator.
Georg Brandl0cdf9a32008-01-26 14:14:20 +00004749
Georg Brandl3ee81df2008-05-17 18:14:43 +00004750- Issue #1920: "while 0" statements were completely removed by the
4751 compiler, even in the presence of an "else" clause, which is
4752 supposed to be run when the condition is false. Now the compiler
4753 correctly emits bytecode for the "else" suite.
Amaury Forgeot d'Arc31eaafe2008-01-24 22:59:25 +00004754

Georg Brandl3ee81df2008-05-17 18:14:43 +00004778- Patch #1816: Added sys.flags structseq. It exposes the status of
4779 most command line arguments and PYTHON* environment variables.
Christian Heimesf31b69f2008-01-14 03:42:48 +00004780
Georg Brandl3ee81df2008-05-17 18:14:43 +00004781- Objects/structseq.c: Implemented new structseq representation. The
4782 patch makes structseqs (e.g. the return value of os.stat) more
4783 readable.
Christian Heimes9c201962008-01-14 03:33:52 +00004784
Georg Brandl3ee81df2008-05-17 18:14:43 +00004785- Patch #1700288: added a type attribute cache that caches method
4786 accesses, resulting in speedups in heavily object-oriented code.
Amaury Forgeot d'Arce4c270c2008-01-14 00:29:41 +00004787
Neal Norwitz3fc15b82008-01-10 05:42:58 +00004788- Bug #1776: __import__() no longer accepts filenames on any platform.
4789 The first parameter to __import__() must be a valid module name.
Christian Heimes3403f152008-01-09 19:56:33 +00004790
Georg Brandlaed6c662008-01-07 17:25:53 +00004791- Patch #1668: renamed THREADDEBUG envvar to PYTHONTHREADDEBUG.
4792
Georg Brandl3ee81df2008-05-17 18:14:43 +00004793- Patch #602345: Add -B command line option, PYTHONDONTWRITEBYTECODE
4794 envvar and sys.dont_write_bytecode attribute. All these can be set
4795 to forbid Python to attempt to write compiled bytecode files.
Georg Brandl2da0fce2008-01-07 17:09:35 +00004796
Georg Brandl3ee81df2008-05-17 18:14:43 +00004797- Improve some exception messages when Windows fails to load an
4798 extension module. Now we get for example '%1 is not a valid Win32
4799 application' instead of 'error code 193'.
Amaury Forgeot d'Arce0b76952008-01-04 02:04:15 +00004800
Georg Brandl3ee81df2008-05-17 18:14:43 +00004801- Bug #1481296: Fixed long(float('nan')) != 0L.

Georg Brandl3ee81df2008-05-17 18:14:43 +00004803- Issue #1640: Added math.isinf(x), math.isnan(x) and math.copysign(x,
4804 y) functions.
Christian Heimese2ca4242008-01-03 20:23:15 +00004805
Christian Heimes0a8143f2007-12-18 23:22:54 +00004806- Issue #1635: Platform independent creation and representation of NaN
Georg Brandl3ee81df2008-05-17 18:14:43 +00004807 and INF. float("nan"), float("inf") and float("-inf") now work on
4808 every platform with IEEE 754 semantics.
Christian Heimes0a8143f2007-12-18 23:22:54 +00004809
Georg Brandl3ee81df2008-05-17 18:14:43 +00004810- Compiler now generates simpler and faster code for dictionary
4811 literals. The oparg for BUILD_MAP now indicates an estimated
4812 dictionary size. There is a new opcode, STORE_MAP, for adding
4813 entries to the dictionary.
Raymond Hettingerfd7ed402007-12-18 21:24:09 +00004814
Georg Brandl3ee81df2008-05-17 18:14:43 +00004815- Issue #1638: %zd configure test fails on Linux.
Christian Heimesdb3d6cb2007-12-16 21:39:43 +00004816
Georg Brandl3ee81df2008-05-17 18:14:43 +00004817- Issue #1620: New property decorator syntax was modifying the
4818 decorator in place instead of creating a new decorator object.
Christian Heimes90e10e72007-12-14 02:35:23 +00004819
Georg Brandl3ee81df2008-05-17 18:14:43 +00004820- Issue #1538: Avoid copying string in split/rsplit if the split char
4821 is not found.
Skip Montanaro26015492007-12-08 15:33:24 +00004822
Andrew M. Kuchling395fe442007-12-05 13:27:20 +00004823- Issue #1553: An erroneous __length_hint__ can make list() raise a
Christian Heimes7cc1c6f2007-12-05 12:52:34 +00004824 SystemError.
4825
Nick Coghlanef01d822007-12-03 12:55:17 +00004826- PEP 366: Allow explicit relative imports when executing modules
4827 inside packages with the -m switch via a new module level
4828 __package__ attribute.
4829

4831 running, and if the deallocation of its frames somehow calls the
4832 PyGILState_Ensure() / PyGILState_Release() functions.
Amaury Forgeot d'Arcbe49a902007-11-30 20:37:22 +00004833

Amaury Forgeot d'Arcce7d10c2007-11-24 13:44:17 +00004837 attribute of an empty cell object.
4838
Georg Brandl3ee81df2008-05-17 18:14:43 +00004839- Issue #1460: The utf-7 incremental decoder did not accept truncated
4840 input. It now correctly saves its state between chunks of data.
Amaury Forgeot d'Arcf57375a2007-11-21 01:38:26 +00004841
Georg Brandl3ee81df2008-05-17 18:14:43 +00004842- Patch #1739468: Directories and zipfiles containing a __main__.py
4843 file can now be directly executed by passing their name to the
4844 interpreter. The directory/zipfile is automatically inserted as the
4845 first entry in sys.path.
Nick Coghlan327a39b2007-11-18 11:56:28 +00004846
Georg Brandl3ee81df2008-05-17 18:14:43 +00004847- Issue #1265: Fix a problem with sys.settrace, if the tracing
4848 function uses a generator expression when at the same time the
4849 executed code is closing a paused generator.
Amaury Forgeot d'Arc0d75f092007-11-13 21:54:28 +00004850
Raymond Hettinger1760c8a2007-11-08 02:52:43 +00004851- sets and frozensets now have an isdisjoint() method.
4852
Raymond Hettinger3f8caa32007-10-24 01:28:33 +00004853- optimize the performance of builtin.sum().
4854
Neal Norwitz44f326e2007-10-05 05:29:17 +00004855- Fix warnings found by the new version of the Coverity checker.
4856
Georg Brandl21e99f42010-03-07 15:23:59 +00004857- The enumerate() built-in function is no longer bounded to sequences
Georg Brandl3ee81df2008-05-17 18:14:43 +00004858 smaller than LONG_MAX. Formerly, it raised an OverflowError. Now,
4859 automatically shifts from ints to longs.
Raymond Hettinger8f669372007-10-03 21:18:11 +00004860
Georg Brandl3ee81df2008-05-17 18:14:43 +00004861- Issue #1686386: Tuple's tp_repr did not take into account the
4862 possibility of having a self-referential tuple, which is possible
4863 from C code. Nor did object's tp_str consider that a type's tp_str
4864 could do something that could lead to an inifinite recursion.
4865 Py_ReprEnter() and Py_EnterRecursiveCall(), respectively, fixed the
4866 issues.
Brett Cannon0b14f242007-09-30 19:45:10 +00004867
Georg Brandl3ee81df2008-05-17 18:14:43 +00004868- Issue #1164: It was possible to trigger deadlock when using the
4869 'print' statement to write to a file since the GIL was not released
4870 as needed. Now PyObject_Print() does the right thing along with
4871 various tp_print implementations of the built-in types and those in
4872 the collections module.
Brett Cannon01531592007-09-17 03:28:34 +00004873
Georg Brandl3ee81df2008-05-17 18:14:43 +00004874- Issue #1147: Exceptions were directly allowing string exceptions in
4875 their throw() method even though string exceptions no longer
4876 allowed.
Brett Cannon4c20bc42007-09-11 21:02:28 +00004877
Georg Brandl3ee81df2008-05-17 18:14:43 +00004878- Issue #1096: Prevent a segfault from getting the repr of a very
4879 deeply nested list by using the recursion counter.
Brett Cannona0c05512007-09-10 21:38:27 +00004880
Brett Cannon1e534b52007-09-07 04:18:30 +00004881- Issue #1202533: Fix infinite recursion calls triggered by calls to
Georg Brandl3ee81df2008-05-17 18:14:43 +00004882 PyObject_Call() never calling back out to Python code to trigger
4883 recursion depth updates/checks. Required the creation of a static
4884 RuntimeError instance in case normalizing an exception put the
4885 recursion check value past its limit. Fixes crashers
4886 infinite_rec_(1|2|4|5).py.
Brett Cannon1e534b52007-09-07 04:18:30 +00004887
Georg Brandl3ee81df2008-05-17 18:14:43 +00004888- Patch #1031213: Decode source line in SyntaxErrors back to its

4892 with %G.
4893
Georg Brandl3ee81df2008-05-17 18:14:43 +00004894- Prevent expandtabs() on string and unicode objects from causing a
4895 segfault when a large width is passed on 32-bit platforms.
Neal Norwitz7dbd2a32007-06-09 03:36:34 +00004896

Neal Norwitz0ac60192007-05-27 04:08:54 +00004901- Add new attribute names for function objects. All the func_* become
Georg Brandl3ee81df2008-05-17 18:14:43 +00004902 __*__ attributes. (Some already existed, e.g., __doc__ and
4903 __name__.)
Neal Norwitz0ac60192007-05-27 04:08:54 +00004904
Neal Norwitz8b2bfbc2007-05-23 06:35:32 +00004905- Add -3 option to the interpreter to warn about features that are
4906 deprecated and will be changed/removed in Python 3.0.
4907
Georg Brandl2134e752007-05-21 20:34:16 +00004908- Patch #1686487: you can now pass any mapping after '**' in function
4909 calls.
4910
Collin Winter62903052007-05-18 23:11:24 +00004911- except clauses may now be spelled either "except E, target:" or
Georg Brandl3ee81df2008-05-17 18:14:43 +00004912 "except E as target:". This is to provide forwards compatibility
4913 with Python 3.0.
Collin Winter62903052007-05-18 23:11:24 +00004914
Brett Cannon229cee22007-05-05 01:34:02 +00004915- Deprecate BaseException.message as per PEP 352.
4916
Georg Brandl3ee81df2008-05-17 18:14:43 +00004917- Issue #1303614: don't expose object's __dict__ when the dict is
Georg Brandl21e99f42010-03-07 15:23:59 +00004918 inherited from a built-in base.
Armin Rigo9790a272007-05-02 19:23:31 +00004919
Vinay Sajip8549ce32007-05-06 17:53:37 +00004920- When __slots__ are set to a unicode string, make it work the same as
Neal Norwitzcbd9ee62007-04-14 05:25:50 +00004921 setting a plain string, ie don't expand to single letter identifiers.
4922
Raymond Hettinger13936692007-04-11 18:40:58 +00004923- Request #1191699: Slices can now be pickled.
4924
Raymond Hettinger4db5fe92007-04-12 04:10:00 +00004925- Request #1193128: str.translate() now allows a None argument for
4926 translations that only remove characters without re-mapping the
4927 remaining characters.
4928
Georg Brandl5cb76c12007-03-21 09:00:39 +00004929- Patch #1682205: a TypeError while unpacking an iterable is no longer
4930 masked by a generic one with the message "unpack non-sequence".
4931
Neal Norwitzaa754b72007-03-21 06:39:48 +00004932- Remove unused file Python/fmod.c.
4933
Guido van Rossum143b5642007-03-23 04:58:42 +00004934- Bug #1683368: The object.__init__() and object.__new__() methods are
4935 now stricter in rejecting excess arguments. The only time when
4936 either allows excess arguments is when it is not overridden and the
4937 other one is. For backwards compatibility, when both are
4938 overridden, it is a deprecation warning (for now; maybe a Py3k
Guido van Rossum234b1ff2007-03-23 19:39:01 +00004939 warning later). Also, type.__init__() insists on the same signature
4940 as supported by type.__new__().
Guido van Rossum143b5642007-03-23 04:58:42 +00004941
Georg Brandl3ee81df2008-05-17 18:14:43 +00004942- Patch #1675423: PyComplex_AsCComplex() now tries to convert an
4943 object to complex using its __complex__() method before falling back
4944 to the __float__() method. Therefore, the functions in the cmath
4945 module now can operate on objects that define a __complex__()
4946 method.
Georg Brandl2b869942007-03-17 16:08:45 +00004947
Georg Brandl3ee81df2008-05-17 18:14:43 +00004948- Patch #1623563: allow __class__ assignment for classes with
4949 __slots__. The old and the new class are still required to have the
4950 same slot names.
Žiga Seilnacht6f2d09c2007-03-16 11:59:38 +00004951
Georg Brandl3ee81df2008-05-17 18:14:43 +00004952- Patch #1642547: Fix an error/crash when encountering syntax errors
4953 in complex if statements.
Collin Winter77c67bd2007-03-16 04:11:30 +00004954
Georg Brandl3ee81df2008-05-17 18:14:43 +00004955- Patch #1462488: Python no longer segfaults when
4956 ``object.__reduce_ex__()`` is called with an object that is faking
4957 its type.
Žiga Seilnacht20f43d32007-03-15 11:44:55 +00004958
Georg Brandl3ee81df2008-05-17 18:14:43 +00004959- Patch #1680015: Don't modify __slots__ tuple if it contains an

Georg Brandl5240d742007-03-13 20:46:32 +00004962- Patch #1444529: the builtin compile() now accepts keyword arguments.
4963
Georg Brandl7b9c5552007-03-12 14:30:05 +00004964- Bug #1678647: write a newline after printing an exception in any
4965 case, even when converting the value to a string failed.
4966
Georg Brandl871f1bc2007-03-12 13:17:36 +00004967- The dir() function has been extended to call the __dir__() method on
Georg Brandl3ee81df2008-05-17 18:14:43 +00004968 its argument, if it exists. If not, it will work like before. This
4969 allows customizing the output of dir() in the presence of a
4970 __getattr__().
Georg Brandl871f1bc2007-03-12 13:17:36 +00004971
Collin Winter276887b2007-03-12 16:11:39 +00004972- Patch #922167: Python no longer segfaults when faced with infinitely
4973 self-recursive reload() calls (as reported by bug #742342).
4974
Georg Brandl3ee81df2008-05-17 18:14:43 +00004975- Patch #1675981: remove unreachable code from ``type.__new__()``

Georg Brandl3ee81df2008-05-17 18:14:43 +00004978- Patch #1491866: change the complex() constructor to allow
4979 parthensized forms. This means complex(repr(x)) now works instead of
4980 raising a ValueError.
Collin Wintere38051d2007-03-09 20:33:07 +00004981
Georg Brandlaa2321b2007-03-07 00:40:28 +00004982- Patch #703779: unset __file__ in __main__ after running a file. This
Georg Brandl3ee81df2008-05-17 18:14:43 +00004983 makes the filenames the warning module prints much more sensible
4984 when a PYTHONSTARTUP file is used.
Georg Brandlaa2321b2007-03-07 00:40:28 +00004985
Georg Brandl49aafc92007-03-07 00:34:46 +00004986- Variant of patch #697613: don't exit the interpreter on a SystemExit
4987 exception if the -i command line option or PYTHONINSPECT environment
Georg Brandl3ee81df2008-05-17 18:14:43 +00004988 variable is given, but break into the interactive interpreter just
4989 like on other exceptions or normal program exit.

Georg Brandl3ee81df2008-05-17 18:14:43 +00004994- Bug #1674503: close the file opened by execfile() in an error
4995 condition.
Georg Brandl098cd692007-03-06 12:17:50 +00004996
Georg Brandl0fca97a2007-03-05 22:28:08 +00004997- Patch #1674228: when assigning a slice (old-style), check for the
4998 sq_ass_slice instead of the sq_slice slot.
4999
Georg Brandl3ee81df2008-05-17 18:14:43 +00005000- When printing an unraisable error, don't print exceptions. before
5001 the name. This duplicates the behavior whening normally printing
5002 exceptions.
Neal Norwitz88516a62007-02-26 22:41:45 +00005003
Georg Brandl3ee81df2008-05-17 18:14:43 +00005004- Bug #1653736: Properly discard third argument to

Georg Brandl3ee81df2008-05-17 18:14:43 +00005010- Bug #1377858: Fix the segfaulting of the interpreter when an object
5011 created a weakref on itself during a __del__ call for new-style
5012 classes (classic classes still have the bug).

Facundo Batistab6a5c9d2007-03-29 18:22:35 +00005504- Added a timeout parameter to the constructor of other protocols
5505 (telnetlib, ftplib, smtplib and poplib). This is second part of the
5506 work started with create_connection() and timeout in httplib, and
5507 closes patch #723312.
5508
Vinay Sajip8549ce32007-05-06 17:53:37 +00005509- Patch #1676823: Added create_connection() to socket.py, which may be
5510 called with a timeout, and use it from httplib (whose HTTPConnection
Facundo Batista70f996b2007-05-21 17:32:32 +00005511 and HTTPSConnection now accept an optional timeout).
Facundo Batista07c78be2007-03-23 18:54:07 +00005512

5533
Georg Brandlf66b6032007-03-14 08:27:52 +00005534- Bug #767111: fix long-standing bug in urllib which caused an
Georg Brandl3ee81df2008-05-17 18:14:43 +00005535 AttributeError instead of an IOError when the server's response
5536 didn't contain a valid HTTP status line.
Georg Brandlf66b6032007-03-14 08:27:52 +00005537
Georg Brandl3ee81df2008-05-17 18:14:43 +00005538- Patch #957650: "%var%" environment variable references are now
5539 properly expanded in ntpath.expandvars(), also "~user" home

Georg Brandl3ee81df2008-05-17 18:14:43 +00005542- Patch #1429539: pdb now correctly initializes the __main__ module
5543 for the debugged script, which means that imports from __main__ work
Georg Brandlb6ae6aa2007-03-13 21:58:44 +00005544 correctly now.
5545
Georg Brandlbad6f192007-03-13 21:32:56 +00005546- The nonobvious commands.getstatus() function is now deprecated.

5552
Georg Brandl3ee81df2008-05-17 18:14:43 +00005553- Patch #1530482: add pydoc.render_doc() which returns the

5563 parameter which can be set to False to prevent the default
5564 delete-on-close behavior.
Georg Brandl35ef9c12007-03-13 18:31:49 +00005565
Georg Brandl9e6b4702007-03-13 18:15:41 +00005566- Patch #1581073: add a flag to textwrap that prevents the dropping of
5567 whitespace while wrapping.
5568
Georg Brandl92a6bae2007-03-13 17:43:32 +00005569- Patch #1603688: ConfigParser.SafeConfigParser now checks values that
Georg Brandl3ee81df2008-05-17 18:14:43 +00005570 are set for invalid interpolation sequences that would lead to
5571 errors on reading back those values.
Georg Brandl92a6bae2007-03-13 17:43:32 +00005572

Georg Brandl3ee81df2008-05-17 18:14:43 +00005587 field names in its exception message if you try to write a record
5588 with a dictionary containing fields not in the CSV field names list.

5614 returned string up to the first NUL character.
5615

5625
Georg Brandl3ee81df2008-05-17 18:14:43 +00005626- unittest now verifies more of its assumptions. In particular,
5627 TestCase and TestSuite subclasses (not instances) are no longer
5628 accepted in TestSuite.addTest(). This should cause no
5629 incompatibility since it never made sense with ordinary subclasses
5630 -- the failure just occurred later, with a more cumbersome
5631 exception.
Georg Brandl9caadf82007-03-08 18:37:31 +00005632

5640 given a unicode argument and os.listdir() returns unicode filenames.
5641
Georg Brandl3ee81df2008-05-17 18:14:43 +00005642- Patch #1673619: setup.py identifies extension modules it doesn't

Georg Brandl3ee81df2008-05-17 18:14:43 +00006020 time so that opening a database previously created with the DB_DUP
6021 or DB_DUPSORT flag set will keep the proper behavior on subsequent
6022 opens. Specifically: dictionary assignment to a DB object will
6023 replace all values for a given key when the database allows
6024 duplicate values. DB users should use DB.put(k, v) when they want
6025 to store duplicates; not DB[k] = v.

6032 characters with ASCII value less than 32. Also, it correctly quotes
6033 dots only if they occur on a single line, as opposed to the previous
6034 behavior of quoting dots if they are the second character of any
6035 line.
