Mark Dickinsond2f3e3f2010-05-05 22:23:58 +0000655 (Optimization was unintentionally turned on in gcc --with-pydebug builds in

678-----------------
679
Philip Jenveyaebbaeb2010-04-06 23:24:45 +0000680- Issue #7301: Add environment variable $PYTHONWARNINGS.
681
Benjamin Peterson3a1dfa22010-04-06 21:50:00 +0000682- Issue #8329: Don't return the same lists from select.select when no fds are
683 changed.
684
Georg Brandlfee0f442010-05-22 21:26:21 +0000685- Issue #8259: ``1L << (2**31)`` no longer produces an 'outrageous shift error'
Mark Dickinson82791672010-04-06 16:47:55 +0000686 on 64-bit machines. The shift count for either left or right shift is
687 permitted to be up to sys.maxsize.
688
Benjamin Peterson4ceeeb02010-04-03 22:48:51 +0000689- Ensure that tokenization of identifiers is not affected by locale.

694
Georg Brandlfee0f442010-05-22 21:26:21 +0000695- Issue #7994: Issue a PendingDeprecationWarning if object.__format__ is called
696 with a non-empty format string. This is an effort to future-proof user
697 code. If a derived class does not currently implement __format__ but later
698 adds its own __format__, it would most likely break user code that had
699 supplied a format string. This will be changed to a DeprecationWaring in
700 Python 3.3 and it will be an error in Python 3.4.
Eric Smithd44b2fc2010-04-02 12:30:56 +0000701
Antoine Pitroua57df2c2010-03-31 21:32:15 +0000702- Issue #8268: Old-style classes (not just instances) now support weak

Antoine Pitrouf9de5342010-04-05 21:35:07 +0000727- Issue #8321: Give access to OpenSSL version numbers from the `ssl` module,
Georg Brandlfee0f442010-05-22 21:26:21 +0000728 using the new attributes `ssl.OPENSSL_VERSION`, `ssl.OPENSSL_VERSION_INFO` and

732
Georg Brandlfee0f442010-05-22 21:26:21 +0000733- Issue #8257: The Decimal construct now accepts a float instance directly,
734 converting that float to a Decimal of equal value:
Mark Dickinson8a950712010-04-03 15:47:46 +0000735
736 >>> Decimal(1.1)

738
Raymond Hettinger34c35b22010-04-03 10:22:00 +0000739- collections.Counter() now supports a subtract() method.
740
Georg Brandlfee0f442010-05-22 21:26:21 +0000741- The functools module now has a total_ordering() class decorator to simplify
742 the specification of rich comparisons.

Georg Brandlfee0f442010-05-22 21:26:21 +0000744- The functools module also adds cmp_to_key() as a tool to transition old-style

Georg Brandlfee0f442010-05-22 21:26:21 +0000750- Issue #7279: Comparisons involving a Decimal signaling NaN now signal
751 InvalidOperation instead of returning False. (Comparisons involving a quiet
752 NaN are unchanged.) Also, Decimal quiet NaNs are now hashable; Decimal
753 signaling NaNs remain unhashable.
Mark Dickinsone096e822010-04-02 10:17:07 +0000754
Georg Brandlfee0f442010-05-22 21:26:21 +0000755- Issue #2531: Comparison operations between floats and Decimal instances now
756 return a result based on the numeric values of the operands; previously they
757 returned an arbitrary result based on the relative ordering of id(float) and
758 id(Decimal).
Mark Dickinson99d80962010-04-02 08:53:22 +0000759
Barry Warsawf7f2d6f2010-03-31 21:07:16 +0000760- Issue #8233: When run as a script, py_compile.py optionally takes a single
Georg Brandlfee0f442010-05-22 21:26:21 +0000761 argument `-` which tells it to read files to compile from stdin. Each line is
762 read on demand and the named file is compiled immediately. (Original patch by
763 Piotr Ożarowski).

Georg Brandlfee0f442010-05-22 21:26:21 +0000772- Comparisons using one of <, <=, >, >= between a complex instance and a
773 Fractions instance now raise TypeError instead of returning True/False. This
774 makes Fraction <=> complex comparisons consistent with int <=> complex, float
775 <=> complex, and complex <=> complex comparisons.

885 and standard packing.)

Georg Brandlba83f822010-03-14 09:50:54 +00001182 specified, rather than fall through to AF_PACKET (in the ``socket`` module).

Georg Brandlba83f822010-03-14 09:50:54 +00001189 file position when calling `truncate()`. It would previously change the file
1190 position to the given argument, which goes against the tradition of
Antoine Pitrouf3fa0742010-01-31 22:26:04 +00001191 ftruncate() and other truncation APIs. Patch by Pascal Chambon.
1192

1194 class used to represent files stored inside an archive. The new
1195 implementation is significantly faster and can be wrapped in a
1196 ``io.BufferedReader`` object for more speedups. It also solves an issue
1197 where interleaved calls to ``read()`` and ``readline()`` give wrong results.
1198 Patch by Nir Aides.

Georg Brandlba83f822010-03-14 09:50:54 +00001208- Issue #7748: Since unicode values are supported for some metadata options in
1209 Distutils, the DistributionMetadata get_* methods will now return an utf-8
1210 encoded string for them. This ensures that the upload and register commands
1211 send the correct values to PyPI without any error.

Georg Brandlba83f822010-03-14 09:50:54 +00001482- Issue #7117: ``repr(x)`` for a float x returns a result based on the shortest
1483 decimal string that's guaranteed to round back to x under correct rounding
1484 (with round-half-to-even rounding mode). Previously it gave a string based on
1485 rounding x to 17 decimal digits. repr(x) for a complex number behaves
1486 similarly. On platforms where the correctly-rounded strtod and dtoa code is
1487 not supported (see below), repr is unchanged.
Mark Dickinsonb678de82009-11-19 18:41:49 +00001488
Georg Brandlba83f822010-03-14 09:50:54 +00001489- Issue #7117: On almost all platforms: float-to-string and string-to-float
1490 conversions within Python are now correctly rounded. Places these conversions
1491 occur include: str for floats and complex numbers; the float and complex
1492 constructors; old-style and new-style numeric formatting; serialization and
1493 deserialization of floats and complex numbers using marshal, pickle and json;
1494 parsing of float and imaginary literals in Python code; Decimal-to-float
1495 conversion.
Mark Dickinsonb678de82009-11-19 18:41:49 +00001496
Georg Brandlba83f822010-03-14 09:50:54 +00001497 The conversions use a Python-adapted version of David Gay's well-known dtoa.c,
1498 providing correctly-rounded strtod and dtoa C functions. This code is
1499 supported on Windows, and on Unix-like platforms using gcc, icc or suncc as
1500 the C compiler. There may be a small number of platforms on which correct
1501 operation of this code cannot be guaranteed, so the code is not used: notably,
1502 this applies to platforms where the C double format is not IEEE 754 binary64,
1503 and to platforms on x86 hardware where the x87 FPU is set to 64-bit precision
1504 and Python's configure script is unable to determine how to change the FPU
1505 precision. On these platforms conversions use the platform strtod and dtoa,
1506 as before.

Georg Brandlba83f822010-03-14 09:50:54 +00001508- Issue #7117: Backport round implementation from Python 3.x. ``round()`` now
1509 uses the correctly-rounded string <-> float conversions described above (when
1510 available), and so produces correctly rounded results that will display nicely
1511 under the float repr. There are two related small changes: (1) round now
1512 accepts any class with an ``__index__()`` method for its second argument (but
1513 no longer accepts floats for the second argument), and (2) an excessively
1514 large second integer argument (e.g., ``round(1.234, 10**100)``) no longer
1515 raises an exception.

1660 (3) the interpretation of fromhex('-nan') didn't match that of float('-nan').

Georg Brandlba83f822010-03-14 09:50:54 +00001662- Issue #5920: For ``float.__format__()``, change the behavior with the empty
1663 presentation type (that is, not one of 'e', 'f', 'g', or 'n') to be like 'g'
1664 but with at least one decimal point and with a default precision
1665 of 12. Previously, the behavior the same but with a default precision of 6.
1666 This more closely matches ``str()``, and reduces surprises when adding
1667 alignment flags to the empty presentation type. This also affects the new
1668 complex.__format__ in the same way.
1669
1670- Issue #5890: In subclasses of 'property' the __doc__ attribute was shadowed by

1865
Georg Brandlba83f822010-03-14 09:50:54 +00001866- Issue #4233: Changed semantic of ``_fileio.FileIO``'s ``close()`` method on
1867 file objects with closefd=False. The file descriptor is still kept open but
1868 the file object behaves like a closed file. The ``FileIO`` object also got a
1869 new readonly attribute ``closefd``.

Georg Brandlba83f822010-03-14 09:50:54 +00001892- On windows, ``os.chdir()`` given unicode was not working if
1893 GetCurrentDirectoryW returned a path longer than MAX_PATH. (But It's doubtful
1894 this code path is really executed because I cannot move to such directory on
1895 win2k)

Georg Brandlba83f822010-03-14 09:50:54 +00001897- Issue #4069: When ``set.remove(element)`` is used with a set element, the
1898 element is temporarily replaced with an equivalent frozenset. But the
1899 eventual KeyError would always report the empty ``frozenset()`` as the missing

Walter Dörwalded960ac2009-05-03 22:36:33 +00001920- Issue #5108: Handle %s like %S and %R in PyUnicode_FromFormatV(): Call
1921 PyUnicode_DecodeUTF8() once, remember the result and output it in a second
1922 step. This avoids problems with counting UTF-8 bytes that ignores the effect
1923 of using the replace error handler in PyUnicode_DecodeUTF8().
1924
Walter Dörwald726ba8e2009-05-06 14:32:35 +00001925- Issue #3739: The unicode-internal encoder now reports the number of characters

Georg Brandlba83f822010-03-14 09:50:54 +00001928- Issue #2422: When compiled with the ``--with-valgrind`` option, the pymalloc

1930 gives improved memory leak detection when running under Valgrind, while taking
1931 advantage of pymalloc at other times.

Nick Coghlan49868cb2009-11-15 07:30:34 +00002003 __main__.py file. This allows applications that run other Python scripts to

3297
Amaury Forgeot d'Arc05e34492008-09-10 22:04:45 +00003298- Issue #3743: In a few places, PY_FORMAT_SIZE_T was incorrectly used with
3299 PyString_FromFormat or PyErr_Format to display size_t values. The macro
3300 PY_FORMAT_SIZE_T is designed to select the correct format for the OS
3301 ``printf`` function, whereas PyString_FromFormat has an independent
3302 implementation and uses "%zd" on all platforms for size_t values.
3303 This makes a difference on win64, where ``printf`` needs "%Id" to display
3304 64bit values.

3310 object; previously an int would be returned for small values. the __long__
3311 method is allowed to return either an int or a long, but the behaviour of

Vinay Sajip35e3b032008-09-01 14:33:59 +00003323- Issue #2534: speed up isinstance() and issubclass() by 50-70%, so as to
Antoine Pitrou0668c622008-08-26 22:42:08 +00003324 match Python 2.5 speed despite the __instancecheck__ / __subclasscheck__
3325 mechanism. In the process, fix a bug where isinstance() and issubclass(),
3326 when given a tuple of classes as second argument, were looking up
3327 __instancecheck__ / __subclasscheck__ on the tuple rather than on each
3328 type object.

3424 _check_logger_class from multiprocessing.
3425
Amaury Forgeot d'Arc293924b2008-09-02 23:19:56 +00003426- Issue #2975: When compiling several extension modules with Visual Studio 2008
3427 from the same python interpreter, some environment variables would grow
3428 without limit.
3429
Benjamin Peterson37346b22008-08-23 20:27:43 +00003430- Issue #3643: Added a few more checks to _testcapi to prevent segfaults by

Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00003467What's New in Python 2.6 beta 3?
3468================================
3469
Barry Warsaw07a4a382008-08-21 01:15:08 +00003470*Release date: 20-Aug-2008*
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00003471
3472Core and Builtins
3473-----------------
3474
Guido van Rossumf8402962008-08-20 15:01:50 +00003475- Issue #1878: Remove Py_TPFLAGS_HAVE_VERSION_TAG from
3476 Py_TPFLAGS_DEFAULT when not building the core. This means 3rd party
3477 extensions do not automatically benefit from the class attribute
3478 cache; they will have to explicitly add Py_TPFLAGS_HAVE_VERSION_TAG
3479 to their tp_flags field if they care. This is a backwards
3480 compatibility feature; in 3.0, all types will use the cache by
3481 default.
3482
Benjamin Petersonf647dc12008-08-20 01:27:30 +00003483- Keyword arguments can now follow starred arguments. (``f(a, *args,
3484 keyword=23)`` is now valid syntax.)
3485
Thomas Heller0ad5ae02008-08-19 19:25:04 +00003486- ctypes function pointers that are COM methods have a boolean True
3487 value again.
3488
Martin v. Löwisf91d46a2008-08-12 14:49:50 +00003489- Issue #3139: Make buffer-interface thread-safe wrt. PyArg_ParseTuple,
3490 by denying s# to parse objects that have a releasebuffer procedure,
3491 and introducing s*.
3492
Georg Brandl1e13ea92008-08-11 09:07:59 +00003493- Issue #3537: Fix an assertion failure when an empty but presized dict
3494 object was stored in the freelist.
3495
Mark Dickinsonb6467572008-08-04 21:30:09 +00003496- Issue #1481296: Make long(float('nan')) and int(float('nan')) raise
3497 ValueError consistently across platforms.
3498
Amaury Forgeot d'Arc39fd6722008-07-31 21:28:03 +00003499- Issue #3479: On platforms where sizeof(int) is smaller than sizeof(long)
3500 (64bit Unix, for example), unichr() would truncate its argument and return
3501 u'\x00' for unichr(2**32). Now it properly raises an OverflowError.
3502
Neal Norwitze7d8be82008-07-31 17:17:14 +00003503- Apply security patches from Apple.
3504
Amaury Forgeot d'Arc246daed2008-07-31 00:42:16 +00003505- Issue #2542: Now that issubclass() may call arbitrary code, ensure that
3506 PyErr_ExceptionMatches returns 0 when an exception occurs there.
3507
Antoine Pitrou92f82162008-07-25 22:22:08 +00003508- Issue #1819: function calls with several named parameters are now on
3509 average 35% faster (as measured by pybench).
3510
Amaury Forgeot d'Arce4921fe2008-07-21 22:00:38 +00003511- Issue #2378: An unexpected UnboundLocalError or NameError could appear when
3512 the python debugger steps into a class statement: the free variables (local
3513 variables defined in an outer scope) would be deleted from the outer scope.
3514
Gregory P. Smith0470bab2008-07-22 04:46:32 +00003515- Issue #2620: Overflow checking when allocating or reallocating memory
3516 was not always being done properly in some python types and extension
3517 modules. PyMem_MALLOC, PyMem_REALLOC, PyMem_NEW and PyMem_RESIZE have
3518 all been updated to perform better checks and places in the code that
3519 would previously leak memory on the error path when such an allocation
3520 failed have been fixed.
3521
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00003522Library
3523-------
3524
Hirokazu Yamamoto838c79f2008-08-20 13:14:07 +00003525- Issue #3612: Added some missing basic types in ctypes.wintypes.
3526
Benjamin Petersone977ad42008-08-20 01:42:01 +00003527- The methods ``is_in_tuple()``, ``is_vararg()``, and ``is_keywordarg()`` of
3528 symtable.Symbol have been deprecated for removal in 3.0 and the next release.
3529
Amaury Forgeot d'Arc351ffb82008-08-18 19:23:47 +00003530- Issue #2234: distutils failed for some versions of the cygwin compiler. The
3531 version reported by these tools does not necessarily follow the python
3532 version numbering scheme, so the module is less strict when parsing it.
3533
Nick Coghlanf70385a2008-08-18 12:42:46 +00003534- Issue #2235: Added Py3k warnings for types which will become unhashable
3535 under the stricter __hash__ inheritance rules in 3.0. Several types
3536 which did not meet the rules for hash invariants and were already
3537 unhashable in 3.0 have now been explicitly flagged as unhashable in
3538 2.6 as well (collections.Mapping, collections.Set, unittest.TestSuite,
3539 xml.dom.minidom.NamedNodeMap, numbers.Number, UserList.UserList)
3540
Brett Cannon88f801d2008-08-18 00:46:22 +00003541- Update __all__ for cookielib, csv, os, urllib2, and weakref to include things
3542 imported into the module but exposed as part of the module's API.
3543
Brett Cannon7b96f072008-08-18 00:41:11 +00003544- Remove an unneeded import of abc.ABCMeta from 'inspect'.
3545

Brett Cannon25c9d6a2008-08-17 22:10:11 +00003548- Remove unneeded imports of 'warnings' from shelve, filecmp, and dummy_thread.
3549
Hirokazu Yamamoto41a81eb2008-08-17 13:10:46 +00003550- Issue #3575: Incremental decoder's decode function now takes bytearray
3551 by using 's*' instead of 't#'.
3552
Mark Dickinson3e4caeb2009-02-21 20:27:01 +00003553- Issue #2222: Fixed reference leak when occurred os.rename()
Hirokazu Yamamoto7f30a682008-08-17 09:46:56 +00003554 fails unicode conversion on 2nd parameter. (windows only)
3555
Georg Brandl222e2082010-08-01 22:27:39 +00003556- Issue #2464: urllib2 now supports a malformation in the URL received
Facundo Batista94f243a2008-08-17 03:38:39 +00003557 in a redirect.
3558
Brett Cannonabe423e2008-08-16 21:47:07 +00003559- Silence the DeprecationWarning raised when importing mimetools in
Brett Cannon721b1452008-08-16 22:00:27 +00003560 BaseHTTPServer, cgi (and rfc822), httplib.
Brett Cannonabe423e2008-08-16 21:47:07 +00003561
Facundo Batistaeb90b782008-08-16 14:44:07 +00003562- Issue #2776: fixed small issue when handling an URL with double slash
3563 after a 302 response in the case of not going through a proxy.
3564
Antoine Pitroub90a8be2008-08-15 21:03:21 +00003565- Issue #2676: in the email package, content-type parsing was hanging on
3566 pathological input because of quadratic or exponential behaviour of a
3567 regular expression.
3568
Antoine Pitrou11ec65d2008-08-14 21:04:30 +00003569- Issue #3476: binary buffered reading through the new "io" library is now
3570 thread-safe.
3571
Brett Cannonbf3157b2008-08-14 05:00:03 +00003572- Silence the DeprecationWarning of rfc822 when it is imported by mimetools
3573 since mimetools itself is deprecated. Because modules are cached, all
3574 subsequent imports of rfc822 will not raise a visible DeprecationWarning.
3575
Antoine Pitrou9fcd4b32008-08-11 17:21:36 +00003576- Issue #3134: shutil referenced undefined WindowsError symbol.
3577
Robert Schuppenies14646332008-08-10 11:01:53 +00003578- Issue #1342811: Fix leak in Tkinter.Menu.delete. Commands associated to
3579 menu entries were not deleted.
3580
Brett Cannon83e81842008-08-09 23:30:55 +00003581- Copied the implementation of reduce() to _functools.reduce() to have a
3582 version that did not raise a DeprecationWarning under -3.
3583
Antoine Pitrou76b8bee2008-08-09 17:27:23 +00003584- Issue #3205: When iterating over a BZ2File fails allocating memory, raise
3585 a MemoryError rather than silently stop the iteration.
3586
Guido van Rossum59ce9012008-08-09 14:55:34 +00003587- Issue #3487: sre "bytecode" validator. Passing invalid "re-bytecode"
3588 to _sre.compile() will now be rejected. This should not affect anybody
3589 since the re.compile() function never generates invalid re-bytecode.
3590
Skip Montanaroa032bf42008-08-08 22:52:51 +00003591- Issue #3436: Make csv.DictReader's fieldnames attribute a property so that
3592 upon first access it can be automatically initialized from the csv file if
3593 it wasn't initialized during instantiation.
3594
Brett Cannon3aa2a492008-08-06 22:28:09 +00003595- Issue #2338: Create imp.reload() to help with transitioning to Python 3.0 as
3596 the reload() built-in has been removed.
3597
Brett Cannon7e30b672008-08-04 21:52:25 +00003598- Changed code in the following modules/packages to remove warnings raised
Brett Cannonc1b76e42008-08-09 23:06:16 +00003599 while running under the ``-3`` flag: aifc, asynchat, asyncore, bdb, bsddb,

3607 raised an AttributeError.
3608
Benjamin Peterson01a24322008-07-28 23:35:27 +00003609- Issue #2523: Fix quadratic behaviour when read()ing a binary file without
Antoine Pitroude781a42008-08-09 12:43:23 +00003610 asking for a specific length. This problem only affected files opened
3611 using the new "io" module, not the built-in open() function.
Benjamin Peterson01a24322008-07-28 23:35:27 +00003612
Mark Dickinsonfe84cce2008-07-27 06:39:07 +00003613- Issue #3449: Update decimal module to use most recent specification

3637 file name rather than a ZipInfo instance, so files are extracted with
3638 mode 0600 rather than 000 under Unix.
3639
Gregory P. Smitha36f8fe2008-08-04 00:13:29 +00003640- Issue #1857: subprocess.Popen.poll gained an additional _deadstate keyword
3641 argument in python 2.5, this broke code that subclassed Popen to include its
3642 own poll method. Fixed my moving _deadstate to an _internal_poll method.

3653 interaction with the tp_hash slot (added in 2.6b2) are now documented
3654
Nick Coghlan2a0c2b12008-08-04 12:47:17 +00003655- Issue #643841: The language reference now provides more detailed
3656 coverage of the lookup process for special methods. The disclaimers
3657 regarding lack of coverage of new-style classes have also been
3658 removed, since the coverage is now fairly reasonable.

Raymond Hettingere3ae6552008-06-20 04:18:15 +00003661What's New in Python 2.6 beta 2?
3662================================
3663
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00003664*Release date: 17-Jul-2008*
3665
Raymond Hettingere3ae6552008-06-20 04:18:15 +00003666Core and Builtins
3667-----------------
3668
Georg Brandl3e483f62008-07-16 22:57:41 +00003669- Issue #3156: Fix inconsistent behavior of the bytearray type: all
3670 its methods now allow for items objects that can be converted to
3671 an integer using operator.index().
3672
Mark Dickinson64b7e502008-07-16 09:40:03 +00003673- Issue #3360: Fix incorrect parsing of '020000000000.0', which
3674 produced a ValueError instead of giving the correct float.
3675
Eric Smitha5fa5a22008-07-16 00:11:49 +00003676- Issue #3083: Add alternate (#) formatting for bin, oct, hex output
3677 for str.format(). This adds the prefix 0b, 0o, or 0x, respectively.
3678
Mark Dickinson7103aa42008-07-15 19:08:33 +00003679- Issue #3008: the float type has a new instance method 'float.hex'
3680 and a new class method 'float.fromhex' to convert floating-point
3681 numbers to and from hexadecimal strings, respectively.
3682
Nick Coghlan6d6bd442008-07-15 15:40:22 +00003683- Issue #2235: __hash__ is once again inherited by default. To allow
3684 collections.Hashable to remain meaningful in the presence of the
3685 default hash implementation (object.__hash__), it is now possible
3686 to explicit block inheritance of hash by setting __hash__=None at
3687 the Python level, or tp_hash=PyObject_HashNotImplemented at the C
3688 level.
3689
Nick Coghlanb028f502008-07-13 14:52:36 +00003690- Issue #3221: Issue a RuntimeWarning instead of raising SystemError if
3691 the parent module cannot be found while performing an absolute import.
3692 This means that an incorrectly defined __package__ attribute will
3693 now only prevent relative imports in that module rather than causing

Georg Brandl5cc774e2008-06-11 20:28:06 +00004167 PPC64 and x86_64 support in one binary).
Ronald Oussoren5640ce22008-06-05 12:58:24 +00004168
4169 This is controlled by the configure argument ``--with-universal-archs``:

4173 - ``--with-universal-archs=32-bit``: install 2-way universal, 32-bit (the default)
4174
4175 - ``--with-universal-archs=64-bit``: install 2-way universal, 64-bit

4216 two handlers that derive the same default base class.

Georg Brandl3ee81df2008-05-17 18:14:43 +00004229- Issue #1631171: Re-implement the 'warnings' module in C (the
4230 original Python code has been kept as backup). This will allow for
4231 using the 'warning's machinery in such places as the parser where
4232 use of pure Python code is not possible. Both the ``showarning()``
4233 and ``formatwarning()`` gain an optional 'line' argument which is
4234 not called by default for backwards-compatibility reasons. Setting
4235 ``warnings.showwarning()`` to an implementation that lacks support
4236 for the ``line`` argument will raise a DeprecationWarning.

Georg Brandl3ee81df2008-05-17 18:14:43 +00004299- Issue #2550: The approach used by client/server code for obtaining
4300 ports to listen on in network-oriented tests has been refined in an
4301 effort to facilitate running multiple instances of the entire
4302 regression test suite in parallel without issue.
4303 test_support.bind_port() has been fixed such that it will always
4304 return a unique port -- which wasn't always the case with the
4305 previous implementation, especially if socket options had been set
4306 that affected address reuse (i.e. SO_REUSEADDR, SO_REUSEPORT). The
4307 new implementation of bind_port() will actually raise an exception
4308 if it is passed an AF_INET/SOCK_STREAM socket with either the
4309 SO_REUSEADDR or SO_REUSEPORT socket option set. Furthermore, if
4310 available, bind_port() will set the SO_EXCLUSIVEADDRUSE option on
4311 the socket it's been passed. This currently only applies to
4312 Windows. This option prevents any other sockets from binding to the
4313 host/port we've bound to, thus removing the possibility of the
4314 'non-deterministic' behaviour, as Microsoft puts it, that occurs
4315 when a second SOCK_STREAM socket binds and accepts to a host/port
4316 that's already been bound by another socket. The optional preferred
4317 port parameter to bind_port() has been removed. Under no
4318 circumstances should tests be hard coding ports!
4319
4320 test_support.find_unused_port() has also been introduced, which will
4321 pass a temporary socket object to bind_port() in order to obtain an
4322 unused port. The temporary socket object is then closed and
4323 deleted, and the port is returned. This method should only be used
4324 for obtaining an unused port in order to pass to an external program
4325 (i.e. the -accept [port] argument to openssl's s_server mode) or as
4326 a parameter to a server-oriented class that doesn't give you direct
4327 access to the underlying socket used.
4328
4329 Finally, test_support.HOST has been introduced, which should be used
4330 for the host argument of any relevant socket calls (i.e. bind and
4331 connect).
Trent Nelsone41b0062008-04-08 23:47:30 +00004332
4333 The following tests were updated to following the new conventions:
Georg Brandl3ee81df2008-05-17 18:14:43 +00004334 test_socket, test_smtplib, test_asyncore, test_ssl, test_httplib,
Trent Nelsone41b0062008-04-08 23:47:30 +00004335 test_poplib, test_ftplib, test_telnetlib, test_socketserver,
4336 test_asynchat and test_socket_ssl.
4337
Georg Brandl3ee81df2008-05-17 18:14:43 +00004338 It is now possible for multiple instances of the regression test
4339 suite to run in parallel without issue.

Eric Smitha73fbe72008-02-23 03:09:44 +00004618- Added the future_builtins module, which contains hex() and oct().
4619 These are the PEP 3127 version of these functions, designed to be
4620 compatible with the hex() and oct() builtins from Python 3.0. They
4621 differ slightly in their output formats from the existing, unchanged
4622 Python 2.6 builtins. The expected usage of the future_builtins
4623 module is:
4624 from future_builtins import hex, oct
4625
Eric Smith7ef40bf2008-02-20 23:34:22 +00004626- Issue #1600: Modifed PyOS_ascii_formatd to use at most 2 digit
4627 exponents for exponents with absolute value < 100. Follows C99
4628 standard. This is a change on Windows, which would use 3 digits.
4629 Also, added 'n' to the formats that PyOS_ascii_formatd understands,
4630 so that any alterations it does to the resulting string will be
4631 available in stringlib/formatter.h (for float.__format__).
4632
Eric Smith5a3c1352008-02-19 13:21:56 +00004633- Implemented PEP 3101, Advanced String Formatting. This adds a new
4634 builtin format(); a format() method for str and unicode; a
4635 __format__() method to object, str, unicode, int, long, float, and
4636 datetime; the class string.Formatter; and the C API
4637 PyObject_Format().
4638
Georg Brandl3ee81df2008-05-17 18:14:43 +00004639- Fixed several potential crashes, all caused by specially crafted
4640 __del__ methods exploiting objects in temporarily inconsistent
4641 state.
Amaury Forgeot d'Arc632fad32008-02-16 20:55:24 +00004642
Vinay Sajipb7edfc42008-04-02 21:10:23 +00004643- Issue #2115: Important speedup in setting __slot__ attributes. Also
Georg Brandl3ee81df2008-05-17 18:14:43 +00004644 prevent a possible crash: an Abstract Base Class would try to access
4645 a slot on a registered virtual subclass.
Amaury Forgeot d'Arc60d6c7f2008-02-15 21:22:45 +00004646

Georg Brandl3ee81df2008-05-17 18:14:43 +00004650- Clear all free lists during a gc.collect() of the highest generation
4651 in order to allow pymalloc to free more arenas. Python may give back
4652 memory to the OS earlier.
Christian Heimes3b718a72008-02-14 12:47:33 +00004653
Georg Brandl3ee81df2008-05-17 18:14:43 +00004654- Issue #2045: Fix an infinite recursion triggered when printing a
4655 subclass of collections.defaultdict, if its default_factory is set
4656 to a bound method.
Amaury Forgeot d'Arcb01aa432008-02-08 00:56:02 +00004657
Christian Heimesf75dbef2008-02-08 00:11:31 +00004658- Fixed a minor memory leak in dictobject.c. The content of the free
4659 list was not freed on interpreter shutdown.
4660
Georg Brandl21e99f42010-03-07 15:23:59 +00004661- Limit free list of method and built-in function objects to 256
Georg Brandl3ee81df2008-05-17 18:14:43 +00004662 entries each.
Christian Heimes6075a822008-02-06 12:44:34 +00004663
Georg Brandl3ee81df2008-05-17 18:14:43 +00004664- Patch #1953: Added ``sys._compact_freelists()`` and the C API
4665 functions ``PyInt_CompactFreeList`` and ``PyFloat_CompactFreeList``
Christian Heimes422051a2008-02-04 18:00:12 +00004666 to compact the internal free lists of pre-allocted ints and floats.
4667
Georg Brandl3ee81df2008-05-17 18:14:43 +00004668- Issue #1983: Fixed return type of fork(), fork1() and forkpty()
4669 calls. Python expected the return type int but the fork familie
4670 returns pi_t.
Christian Heimes951cc0f2008-01-31 23:08:23 +00004671
Georg Brandl3ee81df2008-05-17 18:14:43 +00004672- Issue #1678380: Fix a bug that identifies 0j and -0j when they

4682 the internal lookup cache for ref leak tests.
Christian Heimes908caac2008-01-27 23:34:59 +00004683
Georg Brandl3ee81df2008-05-17 18:14:43 +00004684- Patch #1473257: generator objects gain a gi_code attribute. This is
4685 the same object as the func_code attribute of the function that
4686 produced the generator.
Georg Brandl0cdf9a32008-01-26 14:14:20 +00004687
Georg Brandl3ee81df2008-05-17 18:14:43 +00004688- Issue #1920: "while 0" statements were completely removed by the
4689 compiler, even in the presence of an "else" clause, which is
4690 supposed to be run when the condition is false. Now the compiler
4691 correctly emits bytecode for the "else" suite.
Amaury Forgeot d'Arc31eaafe2008-01-24 22:59:25 +00004692
Guido van Rossumeead05f2008-01-24 18:21:02 +00004693- A few crashers fixed: weakref_in_del.py (issue #1377858);
4694 loosing_dict_ref.py (issue #1303614, test67.py);
4695 borrowed_ref_[34].py (not in tracker).
4696
Vinay Sajipd7cf32e2008-01-24 12:43:33 +00004697- Issue #1069410: The "can't load dll" message box on Windows is
Christian Heimesb2302ba2008-01-23 17:15:06 +00004698 suppressed while an extension is loaded by calling SetErrorMode in
4699 dynload_win.c. The error is still reported properly.
4700
Georg Brandl3ee81df2008-05-17 18:14:43 +00004701- Issue #1915: Python compiles with --enable-unicode=no again. However
Christian Heimes082c9b02008-01-23 14:20:50 +00004702 several extension methods and modules do not work without unicode
4703 support.
4704
Georg Brandl26543b12008-01-21 18:36:51 +00004705- Issue #1882: when compiling code from a string, encoding cookies in the
4706 second line of code were not always recognized correctly.
4707
Georg Brandl14404b62008-01-19 19:27:05 +00004708- Issue #1679: "0x" was taken as a valid integer literal.
4709
Georg Brandl6caad7d2008-01-26 14:19:22 +00004710- Issue #1865: ``bytes`` as an alias for ``str`` and b"" as an alias "" were
Christian Heimes288e89a2008-01-18 18:24:07 +00004711 added.
4712
Christian Heimesc94e2b52008-01-14 04:13:37 +00004713- sys.float_info / PyFloat_GetInfo: The floating point information
4714 object was converted from a dict to a specialized structseq object.
4715
Georg Brandl3ee81df2008-05-17 18:14:43 +00004716- Patch #1816: Added sys.flags structseq. It exposes the status of
4717 most command line arguments and PYTHON* environment variables.
Christian Heimesf31b69f2008-01-14 03:42:48 +00004718
Georg Brandl3ee81df2008-05-17 18:14:43 +00004719- Objects/structseq.c: Implemented new structseq representation. The
4720 patch makes structseqs (e.g. the return value of os.stat) more
4721 readable.
Christian Heimes9c201962008-01-14 03:33:52 +00004722
Georg Brandl3ee81df2008-05-17 18:14:43 +00004723- Patch #1700288: added a type attribute cache that caches method

Georg Brandl3ee81df2008-05-17 18:14:43 +00004745 and INF. float("nan"), float("inf") and float("-inf") now work on
4746 every platform with IEEE 754 semantics.
Christian Heimes0a8143f2007-12-18 23:22:54 +00004747
Georg Brandl3ee81df2008-05-17 18:14:43 +00004748- Compiler now generates simpler and faster code for dictionary
4749 literals. The oparg for BUILD_MAP now indicates an estimated
4750 dictionary size. There is a new opcode, STORE_MAP, for adding
4751 entries to the dictionary.

Georg Brandl3ee81df2008-05-17 18:14:43 +00004796 smaller than LONG_MAX. Formerly, it raised an OverflowError. Now,
4797 automatically shifts from ints to longs.

Georg Brandl3ee81df2008-05-17 18:14:43 +00004799- Issue #1686386: Tuple's tp_repr did not take into account the
4800 possibility of having a self-referential tuple, which is possible
4801 from C code. Nor did object's tp_str consider that a type's tp_str
4802 could do something that could lead to an inifinite recursion.
4803 Py_ReprEnter() and Py_EnterRecursiveCall(), respectively, fixed the
4804 issues.

4807 'print' statement to write to a file since the GIL was not released
4808 as needed. Now PyObject_Print() does the right thing along with
4809 various tp_print implementations of the built-in types and those in
4810 the collections module.

Georg Brandl3ee81df2008-05-17 18:14:43 +00004820 PyObject_Call() never calling back out to Python code to trigger
4821 recursion depth updates/checks. Required the creation of a static

4871
Guido van Rossum143b5642007-03-23 04:58:42 +00004872- Bug #1683368: The object.__init__() and object.__new__() methods are
4873 now stricter in rejecting excess arguments. The only time when
4874 either allows excess arguments is when it is not overridden and the
4875 other one is. For backwards compatibility, when both are
4876 overridden, it is a deprecation warning (for now; maybe a Py3k
Guido van Rossum234b1ff2007-03-23 19:39:01 +00004877 warning later). Also, type.__init__() insists on the same signature
4878 as supported by type.__new__().

Georg Brandl3ee81df2008-05-17 18:14:43 +00004880- Patch #1675423: PyComplex_AsCComplex() now tries to convert an
4881 object to complex using its __complex__() method before falling back
4882 to the __float__() method. Therefore, the functions in the cmath
4883 module now can operate on objects that define a __complex__()
4884 method.

Georg Brandl7b9c5552007-03-12 14:30:05 +00004902- Bug #1678647: write a newline after printing an exception in any
4903 case, even when converting the value to a string failed.
4904
Georg Brandl871f1bc2007-03-12 13:17:36 +00004905- The dir() function has been extended to call the __dir__() method on
Georg Brandl3ee81df2008-05-17 18:14:43 +00004906 its argument, if it exists. If not, it will work like before. This
4907 allows customizing the output of dir() in the presence of a
4908 __getattr__().

4917 parthensized forms. This means complex(repr(x)) now works instead of
4918 raising a ValueError.
Collin Wintere38051d2007-03-09 20:33:07 +00004919
Georg Brandlaa2321b2007-03-07 00:40:28 +00004920- Patch #703779: unset __file__ in __main__ after running a file. This
Georg Brandl3ee81df2008-05-17 18:14:43 +00004921 makes the filenames the warning module prints much more sensible
4922 when a PYTHONSTARTUP file is used.

Georg Brandl0fca97a2007-03-05 22:28:08 +00004935- Patch #1674228: when assigning a slice (old-style), check for the
4936 sq_ass_slice instead of the sq_slice slot.
4937
Georg Brandl3ee81df2008-05-17 18:14:43 +00004938- When printing an unraisable error, don't print exceptions. before

5506
Georg Brandl92a6bae2007-03-13 17:43:32 +00005507- Patch #1603688: ConfigParser.SafeConfigParser now checks values that
Georg Brandl3ee81df2008-05-17 18:14:43 +00005508 are set for invalid interpolation sequences that would lead to

5565 TestCase and TestSuite subclasses (not instances) are no longer
5566 accepted in TestSuite.addTest(). This should cause no

5569 exception.

5852 obtained from the TLS negotiation itself. Patch contributed by Bill
5853 Fenner.
Gregory P. Smith2b3ba582008-01-17 08:03:17 +00005854
Georg Brandl3ee81df2008-05-17 18:14:43 +00005855- Issue #1339: The smtplib.SMTP class has been refactored a bit such
Gregory P. Smithbde4ae42008-01-17 08:35:49 +00005856 that the SMTP.starttls() caller no longer needs to call ehlo()
5857 beforehand. SMTP.starttls() now raises an exception of the server
Georg Brandl3ee81df2008-05-17 18:14:43 +00005858 does not claim to support starttls. Adds the
5859 SMTP.ehlo_or_helo_if_needed() method. Patch contributed by Bill

Georg Brandl3ee81df2008-05-17 18:14:43 +00005958 time so that opening a database previously created with the DB_DUP
5959 or DB_DUPSORT flag set will keep the proper behavior on subsequent
5960 opens. Specifically: dictionary assignment to a DB object will
5961 replace all values for a given key when the database allows
5962 duplicate values. DB users should use DB.put(k, v) when they want
5963 to store duplicates; not DB[k] = v.
Gregory P. Smithec10a4a2007-11-05 02:32:26 +00005964

Raymond Hettingerdc1d1ba2007-11-07 02:45:46 +00006242- Add a FAST_LOOPS build option that speeds-up looping by trading away
Georg Brandl3ee81df2008-05-17 18:14:43 +00006243 periodic threadstate and signal checking in tight loops. By
6244 default, this option is turned-off. It should only be enabled in
6245 debugged, performance critical applications.

6297
Georg Brandl3ee81df2008-05-17 18:14:43 +00006298- Unified naming convention for free lists and their limits. All free
6299 lists in Object/ are named ``free_list``, the counter ``numfree``
6300 and the upper limit is a macro ``PyName_MAXFREELIST`` inside an
6301 #ifndef block.
Christian Heimes5b970ad2008-02-06 13:33:44 +00006302
Georg Brandl3ee81df2008-05-17 18:14:43 +00006303- ``PySet_Add()`` can now modify a newly created frozenset. Similarly
6304 to ``PyTuple_SetItem``, it can be used to populate a brand new
6305 frozenset; but it does not steal a reference to the added item.

6317
Georg Brandl3ee81df2008-05-17 18:14:43 +00006318- Issue #1521: On 64bit platforms, using PyArgs_ParseTuple with the t#
6319 of w# format code incorrectly truncated the length to an int, even
6320 when PY_SSIZE_T_CLEAN is set. The str.decode method used to return
6321 incorrect results with huge strings.
Georg Brandl6caad7d2008-01-26 14:19:22 +00006322
Georg Brandl3ee81df2008-05-17 18:14:43 +00006323- Issue #1629: Renamed Py_Size, Py_Type and Py_Refcnt to Py_SIZE,

6343
6344- Make _PyGILState_NoteThreadState() static, it was not used anywhere
6345 outside of pystate.c and should not be necessary.
6346
Georg Brandl3ee81df2008-05-17 18:14:43 +00006347- ``PyImport_Import`` and ``PyImport_ImportModule`` now always do
6348 absolute imports. In earlier versions they might have used relative
6349 imports under some conditions.
Christian Heimes000a0742008-01-03 22:16:32 +00006350
Georg Brandl3ee81df2008-05-17 18:14:43 +00006351- Added case insensitive comparison methods ``PyOS_stricmp(char*,
6352 char*)`` and ``PyOS_strnicmp(char*, char*, Py_ssize_t)``.
Christian Heimes000a0742008-01-03 22:16:32 +00006353
Georg Brandl3ee81df2008-05-17 18:14:43 +00006354- Bug #1542693: remove semi-colon at end of PyImport_ImportModuleEx

Georg Brandl3ee81df2008-05-17 18:14:43 +00006379- Removed the macfs module. It had been deprecated since Python 2.5.
6380 This lead to the deprecation of macostools.touched() as it relied
