Mark Dickinsond2f3e3f2010-05-05 22:23:58 +0000662 (Optimization was unintentionally turned on in gcc --with-pydebug builds in

685-----------------
686
Philip Jenveyaebbaeb2010-04-06 23:24:45 +0000687- Issue #7301: Add environment variable $PYTHONWARNINGS.
688
Benjamin Peterson3a1dfa22010-04-06 21:50:00 +0000689- Issue #8329: Don't return the same lists from select.select when no fds are
690 changed.
691
Georg Brandlfee0f442010-05-22 21:26:21 +0000692- Issue #8259: ``1L << (2**31)`` no longer produces an 'outrageous shift error'
Mark Dickinson82791672010-04-06 16:47:55 +0000693 on 64-bit machines. The shift count for either left or right shift is
694 permitted to be up to sys.maxsize.
695
Benjamin Peterson4ceeeb02010-04-03 22:48:51 +0000696- Ensure that tokenization of identifiers is not affected by locale.

701
Georg Brandlfee0f442010-05-22 21:26:21 +0000702- Issue #7994: Issue a PendingDeprecationWarning if object.__format__ is called
703 with a non-empty format string. This is an effort to future-proof user
704 code. If a derived class does not currently implement __format__ but later
705 adds its own __format__, it would most likely break user code that had
706 supplied a format string. This will be changed to a DeprecationWaring in
707 Python 3.3 and it will be an error in Python 3.4.

Antoine Pitrouf9de5342010-04-05 21:35:07 +0000734- Issue #8321: Give access to OpenSSL version numbers from the `ssl` module,
Georg Brandlfee0f442010-05-22 21:26:21 +0000735 using the new attributes `ssl.OPENSSL_VERSION`, `ssl.OPENSSL_VERSION_INFO` and

Georg Brandlfee0f442010-05-22 21:26:21 +0000740- Issue #8257: The Decimal construct now accepts a float instance directly,
741 converting that float to a Decimal of equal value:
Mark Dickinson8a950712010-04-03 15:47:46 +0000742

745
Raymond Hettinger34c35b22010-04-03 10:22:00 +0000746- collections.Counter() now supports a subtract() method.
747
Georg Brandlfee0f442010-05-22 21:26:21 +0000748- The functools module now has a total_ordering() class decorator to simplify
749 the specification of rich comparisons.

Georg Brandlfee0f442010-05-22 21:26:21 +0000751- The functools module also adds cmp_to_key() as a tool to transition old-style

Georg Brandlfee0f442010-05-22 21:26:21 +0000757- Issue #7279: Comparisons involving a Decimal signaling NaN now signal
758 InvalidOperation instead of returning False. (Comparisons involving a quiet
759 NaN are unchanged.) Also, Decimal quiet NaNs are now hashable; Decimal
760 signaling NaNs remain unhashable.
Mark Dickinsone096e822010-04-02 10:17:07 +0000761
Georg Brandlfee0f442010-05-22 21:26:21 +0000762- Issue #2531: Comparison operations between floats and Decimal instances now
763 return a result based on the numeric values of the operands; previously they
764 returned an arbitrary result based on the relative ordering of id(float) and
765 id(Decimal).
Mark Dickinson99d80962010-04-02 08:53:22 +0000766
Barry Warsawf7f2d6f2010-03-31 21:07:16 +0000767- Issue #8233: When run as a script, py_compile.py optionally takes a single
Georg Brandlfee0f442010-05-22 21:26:21 +0000768 argument `-` which tells it to read files to compile from stdin. Each line is
769 read on demand and the named file is compiled immediately. (Original patch by
770 Piotr Ożarowski).

Georg Brandlfee0f442010-05-22 21:26:21 +0000779- Comparisons using one of <, <=, >, >= between a complex instance and a
780 Fractions instance now raise TypeError instead of returning True/False. This
781 makes Fraction <=> complex comparisons consistent with int <=> complex, float
782 <=> complex, and complex <=> complex comparisons.

Georg Brandlfee0f442010-05-22 21:26:21 +0000889 produces a DeprecationWarning in this case. (In Python 2.6, the behaviour was
890 inconsistent: __int__ was used for some integer codes but not for others, and
891 the set of integer codes for which it was used differed between native packing
892 and standard packing.)

Georg Brandlba83f822010-03-14 09:50:54 +00001196 file position when calling `truncate()`. It would previously change the file
1197 position to the given argument, which goes against the tradition of

1201 class used to represent files stored inside an archive. The new
1202 implementation is significantly faster and can be wrapped in a

1204 where interleaved calls to ``read()`` and ``readline()`` give wrong results.

1217 encoded string for them. This ensures that the upload and register commands
1218 send the correct values to PyPI without any error.

Georg Brandlba83f822010-03-14 09:50:54 +00001489- Issue #7117: ``repr(x)`` for a float x returns a result based on the shortest
1490 decimal string that's guaranteed to round back to x under correct rounding
1491 (with round-half-to-even rounding mode). Previously it gave a string based on
1492 rounding x to 17 decimal digits. repr(x) for a complex number behaves
1493 similarly. On platforms where the correctly-rounded strtod and dtoa code is
1494 not supported (see below), repr is unchanged.
Mark Dickinsonb678de82009-11-19 18:41:49 +00001495
Georg Brandlba83f822010-03-14 09:50:54 +00001496- Issue #7117: On almost all platforms: float-to-string and string-to-float
1497 conversions within Python are now correctly rounded. Places these conversions
1498 occur include: str for floats and complex numbers; the float and complex
1499 constructors; old-style and new-style numeric formatting; serialization and
1500 deserialization of floats and complex numbers using marshal, pickle and json;
1501 parsing of float and imaginary literals in Python code; Decimal-to-float
1502 conversion.
Mark Dickinsonb678de82009-11-19 18:41:49 +00001503
Georg Brandlba83f822010-03-14 09:50:54 +00001504 The conversions use a Python-adapted version of David Gay's well-known dtoa.c,
1505 providing correctly-rounded strtod and dtoa C functions. This code is
1506 supported on Windows, and on Unix-like platforms using gcc, icc or suncc as
1507 the C compiler. There may be a small number of platforms on which correct
1508 operation of this code cannot be guaranteed, so the code is not used: notably,
1509 this applies to platforms where the C double format is not IEEE 754 binary64,
1510 and to platforms on x86 hardware where the x87 FPU is set to 64-bit precision
1511 and Python's configure script is unable to determine how to change the FPU
1512 precision. On these platforms conversions use the platform strtod and dtoa,
1513 as before.

Georg Brandlba83f822010-03-14 09:50:54 +00001515- Issue #7117: Backport round implementation from Python 3.x. ``round()`` now
1516 uses the correctly-rounded string <-> float conversions described above (when
1517 available), and so produces correctly rounded results that will display nicely
1518 under the float repr. There are two related small changes: (1) round now
1519 accepts any class with an ``__index__()`` method for its second argument (but
1520 no longer accepts floats for the second argument), and (2) an excessively
1521 large second integer argument (e.g., ``round(1.234, 10**100)``) no longer
1522 raises an exception.

1672 of 12. Previously, the behavior the same but with a default precision of 6.
1673 This more closely matches ``str()``, and reduces surprises when adding

Georg Brandlba83f822010-03-14 09:50:54 +00001815- Issue #1180193: When importing a module from a .pyc (or .pyo) file with an
1816 existing .py counterpart, override the co_filename attributes of all code
1817 objects if the original filename is obsolete (which can happen if the file has

1872
Georg Brandlba83f822010-03-14 09:50:54 +00001873- Issue #4233: Changed semantic of ``_fileio.FileIO``'s ``close()`` method on
1874 file objects with closefd=False. The file descriptor is still kept open but
1875 the file object behaves like a closed file. The ``FileIO`` object also got a
1876 new readonly attribute ``closefd``.

1895
Benjamin Peterson399b1fe2008-10-25 02:53:28 +00001896- Using ``nonlocal`` as a variable name will now raise a Py3k SyntaxWarning

Georg Brandlba83f822010-03-14 09:50:54 +00001899- On windows, ``os.chdir()`` given unicode was not working if
1900 GetCurrentDirectoryW returned a path longer than MAX_PATH. (But It's doubtful
1901 this code path is really executed because I cannot move to such directory on
1902 win2k)

Georg Brandlba83f822010-03-14 09:50:54 +00001904- Issue #4069: When ``set.remove(element)`` is used with a set element, the
1905 element is temporarily replaced with an equivalent frozenset. But the
1906 eventual KeyError would always report the empty ``frozenset()`` as the missing
1907 key. Now it correctly refers to the initial element.

Walter Dörwalded960ac2009-05-03 22:36:33 +00001927- Issue #5108: Handle %s like %S and %R in PyUnicode_FromFormatV(): Call
1928 PyUnicode_DecodeUTF8() once, remember the result and output it in a second
1929 step. This avoids problems with counting UTF-8 bytes that ignores the effect
1930 of using the replace error handler in PyUnicode_DecodeUTF8().
1931
Walter Dörwald726ba8e2009-05-06 14:32:35 +00001932- Issue #3739: The unicode-internal encoder now reports the number of characters

1934
Georg Brandlba83f822010-03-14 09:50:54 +00001935- Issue #2422: When compiled with the ``--with-valgrind`` option, the pymalloc

1937 gives improved memory leak detection when running under Valgrind, while taking
1938 advantage of pymalloc at other times.

3304
Amaury Forgeot d'Arc05e34492008-09-10 22:04:45 +00003305- Issue #3743: In a few places, PY_FORMAT_SIZE_T was incorrectly used with
3306 PyString_FromFormat or PyErr_Format to display size_t values. The macro
3307 PY_FORMAT_SIZE_T is designed to select the correct format for the OS
3308 ``printf`` function, whereas PyString_FromFormat has an independent
3309 implementation and uses "%zd" on all platforms for size_t values.
3310 This makes a difference on win64, where ``printf`` needs "%Id" to display
3311 64bit values.

Benjamin Peterson97179b02008-09-09 20:55:01 +00003313- Issue #3634: _weakref.ref(Exception).__init__() gave invalid return value on

3317 object; previously an int would be returned for small values. the __long__

Antoine Pitroud4ae97b2008-08-29 18:39:48 +00003328 was correctly parsed but parsing of subsequent arguments failed.
3329
Vinay Sajip35e3b032008-09-01 14:33:59 +00003330- Issue #2534: speed up isinstance() and issubclass() by 50-70%, so as to
Antoine Pitrou0668c622008-08-26 22:42:08 +00003331 match Python 2.5 speed despite the __instancecheck__ / __subclasscheck__
3332 mechanism. In the process, fix a bug where isinstance() and issubclass(),
3333 when given a tuple of classes as second argument, were looking up
3334 __instancecheck__ / __subclasscheck__ on the tuple rather than on each
3335 type object.

Brett Cannon1eaf0742008-09-02 01:25:16 +00003406 warnings.catch_warnings() along with some API cleanup. Expanding the tests
3407 for catch_warnings() also led to an improvement in the raising of a
3408 DeprecationWarning related to warnings.warn_explicit().
3409
Benjamin Peterson973e6c22008-09-01 23:12:58 +00003410- The deprecation warnings for the old camelCase threading API were removed.
3411

3413
Christian Heimesa27a62e2008-08-22 19:55:54 +00003414- Silenced a trivial compiler warning in the sqlite module.
3415
Christian Heimes1cc69632008-08-22 20:10:27 +00003416- Fixed two format strings in the _collections module.
3417
Benjamin Peterson17f03ca2008-09-01 14:18:30 +00003418- Issue #3703: _fileio.FileIO gave unhelpful error message when trying to open a

Gregory P. Smithd7122032008-09-02 05:36:11 +00003421- Issue #3708: os.urandom no longer goes into an infinite loop when passed a
3422 non-integer floating point number.
3423
Vinay Sajip65d66e12008-09-04 07:31:21 +00003424- Issue #3110: multiprocessing fails to compiel on solaris 10 due to missing

3429
Jesse Noller438195f2009-01-18 21:04:36 +00003430- Issue #4301: Patch the logging module to add processName support, remove
3431 _check_logger_class from multiprocessing.
3432
Amaury Forgeot d'Arc293924b2008-09-02 23:19:56 +00003433- Issue #2975: When compiling several extension modules with Visual Studio 2008
3434 from the same python interpreter, some environment variables would grow
3435 without limit.
3436
Benjamin Peterson37346b22008-08-23 20:27:43 +00003437- Issue #3643: Added a few more checks to _testcapi to prevent segfaults by
3438 exploitation of poor argument checking.
3439
Gerhard Häringef2276b2008-09-12 13:54:06 +00003440- sqlite3: Changed docstring of iterdump() to mark method as "Non-standard".
3441
Gerhard Häring6e1afcf2008-09-12 18:58:57 +00003442- Issue #3103: Reduced globals symbols used by sqlite3 module and made sure all
3443 remaining ones have "pysqlite_" prefix.
3444
Gerhard Häringe6872eb2008-09-12 22:33:22 +00003445- Issue #3846: Release the GIL during sqlite3_prepare calls. This improves

3453 wrapper for warnings.catch_warnings() that makes it easier to check
3454 that expected warning messages are being reported.
3455
Amaury Forgeot d'Arcfeb8cad2008-09-06 20:53:51 +00003456- Issue #3796: Some tests functions were not enabled in test_float.

Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00003474What's New in Python 2.6 beta 3?
3475================================
3476
Barry Warsaw07a4a382008-08-21 01:15:08 +00003477*Release date: 20-Aug-2008*
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00003478
3479Core and Builtins
3480-----------------
3481
Guido van Rossumf8402962008-08-20 15:01:50 +00003482- Issue #1878: Remove Py_TPFLAGS_HAVE_VERSION_TAG from
3483 Py_TPFLAGS_DEFAULT when not building the core. This means 3rd party
3484 extensions do not automatically benefit from the class attribute
3485 cache; they will have to explicitly add Py_TPFLAGS_HAVE_VERSION_TAG
3486 to their tp_flags field if they care. This is a backwards
3487 compatibility feature; in 3.0, all types will use the cache by
3488 default.
3489
Benjamin Petersonf647dc12008-08-20 01:27:30 +00003490- Keyword arguments can now follow starred arguments. (``f(a, *args,
3491 keyword=23)`` is now valid syntax.)
3492
Thomas Heller0ad5ae02008-08-19 19:25:04 +00003493- ctypes function pointers that are COM methods have a boolean True
3494 value again.
3495
Martin v. Löwisf91d46a2008-08-12 14:49:50 +00003496- Issue #3139: Make buffer-interface thread-safe wrt. PyArg_ParseTuple,
3497 by denying s# to parse objects that have a releasebuffer procedure,
3498 and introducing s*.
3499
Georg Brandl1e13ea92008-08-11 09:07:59 +00003500- Issue #3537: Fix an assertion failure when an empty but presized dict
3501 object was stored in the freelist.
3502
Mark Dickinsonb6467572008-08-04 21:30:09 +00003503- Issue #1481296: Make long(float('nan')) and int(float('nan')) raise
3504 ValueError consistently across platforms.
3505
Amaury Forgeot d'Arc39fd6722008-07-31 21:28:03 +00003506- Issue #3479: On platforms where sizeof(int) is smaller than sizeof(long)
3507 (64bit Unix, for example), unichr() would truncate its argument and return
3508 u'\x00' for unichr(2**32). Now it properly raises an OverflowError.
3509
Neal Norwitze7d8be82008-07-31 17:17:14 +00003510- Apply security patches from Apple.
3511
Amaury Forgeot d'Arc246daed2008-07-31 00:42:16 +00003512- Issue #2542: Now that issubclass() may call arbitrary code, ensure that
3513 PyErr_ExceptionMatches returns 0 when an exception occurs there.
3514
Antoine Pitrou92f82162008-07-25 22:22:08 +00003515- Issue #1819: function calls with several named parameters are now on
3516 average 35% faster (as measured by pybench).
3517
Amaury Forgeot d'Arce4921fe2008-07-21 22:00:38 +00003518- Issue #2378: An unexpected UnboundLocalError or NameError could appear when
3519 the python debugger steps into a class statement: the free variables (local
3520 variables defined in an outer scope) would be deleted from the outer scope.
3521
Gregory P. Smith0470bab2008-07-22 04:46:32 +00003522- Issue #2620: Overflow checking when allocating or reallocating memory
3523 was not always being done properly in some python types and extension
3524 modules. PyMem_MALLOC, PyMem_REALLOC, PyMem_NEW and PyMem_RESIZE have
3525 all been updated to perform better checks and places in the code that
3526 would previously leak memory on the error path when such an allocation
3527 failed have been fixed.
3528
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00003529Library
3530-------
3531
Hirokazu Yamamoto838c79f2008-08-20 13:14:07 +00003532- Issue #3612: Added some missing basic types in ctypes.wintypes.
3533
Benjamin Petersone977ad42008-08-20 01:42:01 +00003534- The methods ``is_in_tuple()``, ``is_vararg()``, and ``is_keywordarg()`` of
3535 symtable.Symbol have been deprecated for removal in 3.0 and the next release.
3536
Amaury Forgeot d'Arc351ffb82008-08-18 19:23:47 +00003537- Issue #2234: distutils failed for some versions of the cygwin compiler. The
3538 version reported by these tools does not necessarily follow the python
3539 version numbering scheme, so the module is less strict when parsing it.
3540
Nick Coghlanf70385a2008-08-18 12:42:46 +00003541- Issue #2235: Added Py3k warnings for types which will become unhashable
3542 under the stricter __hash__ inheritance rules in 3.0. Several types
3543 which did not meet the rules for hash invariants and were already
3544 unhashable in 3.0 have now been explicitly flagged as unhashable in
3545 2.6 as well (collections.Mapping, collections.Set, unittest.TestSuite,
3546 xml.dom.minidom.NamedNodeMap, numbers.Number, UserList.UserList)
3547
Brett Cannon88f801d2008-08-18 00:46:22 +00003548- Update __all__ for cookielib, csv, os, urllib2, and weakref to include things
3549 imported into the module but exposed as part of the module's API.
3550
Brett Cannon7b96f072008-08-18 00:41:11 +00003551- Remove an unneeded import of abc.ABCMeta from 'inspect'.
3552
Brett Cannon46225e72008-08-18 00:36:52 +00003553- Remove unneeded imports of 'sys' and 'warnings' from 'io'.

Brett Cannon25c9d6a2008-08-17 22:10:11 +00003555- Remove unneeded imports of 'warnings' from shelve, filecmp, and dummy_thread.
3556
Hirokazu Yamamoto41a81eb2008-08-17 13:10:46 +00003557- Issue #3575: Incremental decoder's decode function now takes bytearray
3558 by using 's*' instead of 't#'.
3559
Mark Dickinson3e4caeb2009-02-21 20:27:01 +00003560- Issue #2222: Fixed reference leak when occurred os.rename()
Hirokazu Yamamoto7f30a682008-08-17 09:46:56 +00003561 fails unicode conversion on 2nd parameter. (windows only)
3562
Georg Brandl222e2082010-08-01 22:27:39 +00003563- Issue #2464: urllib2 now supports a malformation in the URL received
Facundo Batista94f243a2008-08-17 03:38:39 +00003564 in a redirect.
3565
Brett Cannonabe423e2008-08-16 21:47:07 +00003566- Silence the DeprecationWarning raised when importing mimetools in
Brett Cannon721b1452008-08-16 22:00:27 +00003567 BaseHTTPServer, cgi (and rfc822), httplib.
Brett Cannonabe423e2008-08-16 21:47:07 +00003568
Facundo Batistaeb90b782008-08-16 14:44:07 +00003569- Issue #2776: fixed small issue when handling an URL with double slash
3570 after a 302 response in the case of not going through a proxy.
3571
Antoine Pitroub90a8be2008-08-15 21:03:21 +00003572- Issue #2676: in the email package, content-type parsing was hanging on
3573 pathological input because of quadratic or exponential behaviour of a
3574 regular expression.
3575
Antoine Pitrou11ec65d2008-08-14 21:04:30 +00003576- Issue #3476: binary buffered reading through the new "io" library is now
3577 thread-safe.
3578
Brett Cannonbf3157b2008-08-14 05:00:03 +00003579- Silence the DeprecationWarning of rfc822 when it is imported by mimetools
3580 since mimetools itself is deprecated. Because modules are cached, all
3581 subsequent imports of rfc822 will not raise a visible DeprecationWarning.
3582
Antoine Pitrou9fcd4b32008-08-11 17:21:36 +00003583- Issue #3134: shutil referenced undefined WindowsError symbol.
3584
Robert Schuppenies14646332008-08-10 11:01:53 +00003585- Issue #1342811: Fix leak in Tkinter.Menu.delete. Commands associated to
3586 menu entries were not deleted.
3587
Brett Cannon83e81842008-08-09 23:30:55 +00003588- Copied the implementation of reduce() to _functools.reduce() to have a
3589 version that did not raise a DeprecationWarning under -3.
3590
Antoine Pitrou76b8bee2008-08-09 17:27:23 +00003591- Issue #3205: When iterating over a BZ2File fails allocating memory, raise
3592 a MemoryError rather than silently stop the iteration.
3593
Guido van Rossum59ce9012008-08-09 14:55:34 +00003594- Issue #3487: sre "bytecode" validator. Passing invalid "re-bytecode"
3595 to _sre.compile() will now be rejected. This should not affect anybody
3596 since the re.compile() function never generates invalid re-bytecode.
3597
Skip Montanaroa032bf42008-08-08 22:52:51 +00003598- Issue #3436: Make csv.DictReader's fieldnames attribute a property so that
3599 upon first access it can be automatically initialized from the csv file if
3600 it wasn't initialized during instantiation.
3601
Brett Cannon3aa2a492008-08-06 22:28:09 +00003602- Issue #2338: Create imp.reload() to help with transitioning to Python 3.0 as
3603 the reload() built-in has been removed.
3604
Brett Cannon7e30b672008-08-04 21:52:25 +00003605- Changed code in the following modules/packages to remove warnings raised
Brett Cannonc1b76e42008-08-09 23:06:16 +00003606 while running under the ``-3`` flag: aifc, asynchat, asyncore, bdb, bsddb,

Antoine Pitroude781a42008-08-09 12:43:23 +00003617 asking for a specific length. This problem only affected files opened
3618 using the new "io" module, not the built-in open() function.
Benjamin Peterson01a24322008-07-28 23:35:27 +00003619

3644 file name rather than a ZipInfo instance, so files are extracted with
3645 mode 0600 rather than 000 under Unix.
3646
Gregory P. Smitha36f8fe2008-08-04 00:13:29 +00003647- Issue #1857: subprocess.Popen.poll gained an additional _deadstate keyword
3648 argument in python 2.5, this broke code that subclassed Popen to include its
3649 own poll method. Fixed my moving _deadstate to an _internal_poll method.

3663 coverage of the lookup process for special methods. The disclaimers
3664 regarding lack of coverage of new-style classes have also been
3665 removed, since the coverage is now fairly reasonable.

3674-----------------
3675
Georg Brandl3e483f62008-07-16 22:57:41 +00003676- Issue #3156: Fix inconsistent behavior of the bytearray type: all
3677 its methods now allow for items objects that can be converted to
3678 an integer using operator.index().
3679
Mark Dickinson64b7e502008-07-16 09:40:03 +00003680- Issue #3360: Fix incorrect parsing of '020000000000.0', which
3681 produced a ValueError instead of giving the correct float.
3682
Eric Smitha5fa5a22008-07-16 00:11:49 +00003683- Issue #3083: Add alternate (#) formatting for bin, oct, hex output
3684 for str.format(). This adds the prefix 0b, 0o, or 0x, respectively.
3685
Mark Dickinson7103aa42008-07-15 19:08:33 +00003686- Issue #3008: the float type has a new instance method 'float.hex'
3687 and a new class method 'float.fromhex' to convert floating-point
3688 numbers to and from hexadecimal strings, respectively.
3689
Nick Coghlan6d6bd442008-07-15 15:40:22 +00003690- Issue #2235: __hash__ is once again inherited by default. To allow
3691 collections.Hashable to remain meaningful in the presence of the

Nick Coghlanb028f502008-07-13 14:52:36 +00003697- Issue #3221: Issue a RuntimeWarning instead of raising SystemError if
3698 the parent module cannot be found while performing an absolute import.
3699 This means that an incorrectly defined __package__ attribute will
3700 now only prevent relative imports in that module rather than causing
3701 all imports from that module to fail.

Mark Dickinson1ec2fcd2008-06-20 14:53:43 +00003715- Issue #3004: Minor change to slice.indices(): the start and stop
3716 arguments are now treated identically, making the behaviour easier
3717 to describe and understand. For example, slice(None, -10,
3718 1).indices(9) now returns (0, 0, 1) instead of (0, -1, 1), and
3719 slice(None, 10, -1).indices(10) returns (9, 9, -1) instead of (9,
3720 10, -1).

Georg Brandl5cc774e2008-06-11 20:28:06 +00004174 PPC64 and x86_64 support in one binary).
Ronald Oussoren5640ce22008-06-05 12:58:24 +00004175

4223 two handlers that derive the same default base class.

Georg Brandl3ee81df2008-05-17 18:14:43 +00004236- Issue #1631171: Re-implement the 'warnings' module in C (the
4237 original Python code has been kept as backup). This will allow for
4238 using the 'warning's machinery in such places as the parser where
4239 use of pure Python code is not possible. Both the ``showarning()``
4240 and ``formatwarning()`` gain an optional 'line' argument which is
4241 not called by default for backwards-compatibility reasons. Setting
4242 ``warnings.showwarning()`` to an implementation that lacks support
4243 for the ``line`` argument will raise a DeprecationWarning.

Georg Brandl3ee81df2008-05-17 18:14:43 +00004306- Issue #2550: The approach used by client/server code for obtaining
4307 ports to listen on in network-oriented tests has been refined in an
4308 effort to facilitate running multiple instances of the entire
4309 regression test suite in parallel without issue.
4310 test_support.bind_port() has been fixed such that it will always
4311 return a unique port -- which wasn't always the case with the
4312 previous implementation, especially if socket options had been set
4313 that affected address reuse (i.e. SO_REUSEADDR, SO_REUSEPORT). The
4314 new implementation of bind_port() will actually raise an exception
4315 if it is passed an AF_INET/SOCK_STREAM socket with either the
4316 SO_REUSEADDR or SO_REUSEPORT socket option set. Furthermore, if
4317 available, bind_port() will set the SO_EXCLUSIVEADDRUSE option on
4318 the socket it's been passed. This currently only applies to
4319 Windows. This option prevents any other sockets from binding to the
4320 host/port we've bound to, thus removing the possibility of the
4321 'non-deterministic' behaviour, as Microsoft puts it, that occurs
4322 when a second SOCK_STREAM socket binds and accepts to a host/port
4323 that's already been bound by another socket. The optional preferred
4324 port parameter to bind_port() has been removed. Under no
4325 circumstances should tests be hard coding ports!
4326
4327 test_support.find_unused_port() has also been introduced, which will
4328 pass a temporary socket object to bind_port() in order to obtain an
4329 unused port. The temporary socket object is then closed and
4330 deleted, and the port is returned. This method should only be used
4331 for obtaining an unused port in order to pass to an external program
4332 (i.e. the -accept [port] argument to openssl's s_server mode) or as
4333 a parameter to a server-oriented class that doesn't give you direct
4334 access to the underlying socket used.
4335
4336 Finally, test_support.HOST has been introduced, which should be used
4337 for the host argument of any relevant socket calls (i.e. bind and
4338 connect).
Trent Nelsone41b0062008-04-08 23:47:30 +00004339
4340 The following tests were updated to following the new conventions:
Georg Brandl3ee81df2008-05-17 18:14:43 +00004341 test_socket, test_smtplib, test_asyncore, test_ssl, test_httplib,
Trent Nelsone41b0062008-04-08 23:47:30 +00004342 test_poplib, test_ftplib, test_telnetlib, test_socketserver,
4343 test_asynchat and test_socket_ssl.
4344
Georg Brandl3ee81df2008-05-17 18:14:43 +00004345 It is now possible for multiple instances of the regression test
4346 suite to run in parallel without issue.

Eric Smitha73fbe72008-02-23 03:09:44 +00004625- Added the future_builtins module, which contains hex() and oct().
4626 These are the PEP 3127 version of these functions, designed to be
4627 compatible with the hex() and oct() builtins from Python 3.0. They
4628 differ slightly in their output formats from the existing, unchanged
4629 Python 2.6 builtins. The expected usage of the future_builtins
4630 module is:
4631 from future_builtins import hex, oct
4632
Eric Smith7ef40bf2008-02-20 23:34:22 +00004633- Issue #1600: Modifed PyOS_ascii_formatd to use at most 2 digit
4634 exponents for exponents with absolute value < 100. Follows C99
4635 standard. This is a change on Windows, which would use 3 digits.
4636 Also, added 'n' to the formats that PyOS_ascii_formatd understands,
4637 so that any alterations it does to the resulting string will be
4638 available in stringlib/formatter.h (for float.__format__).
4639
Eric Smith5a3c1352008-02-19 13:21:56 +00004640- Implemented PEP 3101, Advanced String Formatting. This adds a new
4641 builtin format(); a format() method for str and unicode; a
4642 __format__() method to object, str, unicode, int, long, float, and
4643 datetime; the class string.Formatter; and the C API
4644 PyObject_Format().
4645
Georg Brandl3ee81df2008-05-17 18:14:43 +00004646- Fixed several potential crashes, all caused by specially crafted
4647 __del__ methods exploiting objects in temporarily inconsistent
4648 state.
Amaury Forgeot d'Arc632fad32008-02-16 20:55:24 +00004649
Vinay Sajipb7edfc42008-04-02 21:10:23 +00004650- Issue #2115: Important speedup in setting __slot__ attributes. Also
Georg Brandl3ee81df2008-05-17 18:14:43 +00004651 prevent a possible crash: an Abstract Base Class would try to access
4652 a slot on a registered virtual subclass.
Amaury Forgeot d'Arc60d6c7f2008-02-15 21:22:45 +00004653
Georg Brandl3ee81df2008-05-17 18:14:43 +00004654- Fixed repr() and str() of complex numbers with infinity or nan as
4655 real or imaginary part.

Georg Brandl3ee81df2008-05-17 18:14:43 +00004657- Clear all free lists during a gc.collect() of the highest generation
4658 in order to allow pymalloc to free more arenas. Python may give back
4659 memory to the OS earlier.
Christian Heimes3b718a72008-02-14 12:47:33 +00004660
Georg Brandl3ee81df2008-05-17 18:14:43 +00004661- Issue #2045: Fix an infinite recursion triggered when printing a
4662 subclass of collections.defaultdict, if its default_factory is set
4663 to a bound method.
Amaury Forgeot d'Arcb01aa432008-02-08 00:56:02 +00004664
Christian Heimesf75dbef2008-02-08 00:11:31 +00004665- Fixed a minor memory leak in dictobject.c. The content of the free
4666 list was not freed on interpreter shutdown.
4667
Georg Brandl21e99f42010-03-07 15:23:59 +00004668- Limit free list of method and built-in function objects to 256
Georg Brandl3ee81df2008-05-17 18:14:43 +00004669 entries each.
Christian Heimes6075a822008-02-06 12:44:34 +00004670
Georg Brandl3ee81df2008-05-17 18:14:43 +00004671- Patch #1953: Added ``sys._compact_freelists()`` and the C API
4672 functions ``PyInt_CompactFreeList`` and ``PyFloat_CompactFreeList``
Christian Heimes422051a2008-02-04 18:00:12 +00004673 to compact the internal free lists of pre-allocted ints and floats.
4674
Georg Brandl3ee81df2008-05-17 18:14:43 +00004675- Issue #1983: Fixed return type of fork(), fork1() and forkpty()
4676 calls. Python expected the return type int but the fork familie
4677 returns pi_t.
Christian Heimes951cc0f2008-01-31 23:08:23 +00004678
Georg Brandl3ee81df2008-05-17 18:14:43 +00004679- Issue #1678380: Fix a bug that identifies 0j and -0j when they
4680 appear in the same code unit.
Mark Dickinson105be772008-01-31 22:17:37 +00004681
Georg Brandl3ee81df2008-05-17 18:14:43 +00004682- Issue #2025: Add tuple.count() and tuple.index() methods to comply
4683 with the collections.Sequence API.

Georg Brandl3ee81df2008-05-17 18:14:43 +00004688- Added ``PyType_ClearCache()`` and ``sys._clear_type_cache`` to clear
4689 the internal lookup cache for ref leak tests.
Christian Heimes908caac2008-01-27 23:34:59 +00004690
Georg Brandl3ee81df2008-05-17 18:14:43 +00004691- Patch #1473257: generator objects gain a gi_code attribute. This is
4692 the same object as the func_code attribute of the function that
4693 produced the generator.
Georg Brandl0cdf9a32008-01-26 14:14:20 +00004694
Georg Brandl3ee81df2008-05-17 18:14:43 +00004695- Issue #1920: "while 0" statements were completely removed by the
4696 compiler, even in the presence of an "else" clause, which is
4697 supposed to be run when the condition is false. Now the compiler
4698 correctly emits bytecode for the "else" suite.
Amaury Forgeot d'Arc31eaafe2008-01-24 22:59:25 +00004699
Guido van Rossumeead05f2008-01-24 18:21:02 +00004700- A few crashers fixed: weakref_in_del.py (issue #1377858);
4701 loosing_dict_ref.py (issue #1303614, test67.py);
4702 borrowed_ref_[34].py (not in tracker).
4703
Vinay Sajipd7cf32e2008-01-24 12:43:33 +00004704- Issue #1069410: The "can't load dll" message box on Windows is
Christian Heimesb2302ba2008-01-23 17:15:06 +00004705 suppressed while an extension is loaded by calling SetErrorMode in
4706 dynload_win.c. The error is still reported properly.
4707
Georg Brandl3ee81df2008-05-17 18:14:43 +00004708- Issue #1915: Python compiles with --enable-unicode=no again. However
Christian Heimes082c9b02008-01-23 14:20:50 +00004709 several extension methods and modules do not work without unicode
4710 support.
4711
Georg Brandl26543b12008-01-21 18:36:51 +00004712- Issue #1882: when compiling code from a string, encoding cookies in the
4713 second line of code were not always recognized correctly.
4714
Georg Brandl14404b62008-01-19 19:27:05 +00004715- Issue #1679: "0x" was taken as a valid integer literal.
4716
Georg Brandl6caad7d2008-01-26 14:19:22 +00004717- Issue #1865: ``bytes`` as an alias for ``str`` and b"" as an alias "" were
Christian Heimes288e89a2008-01-18 18:24:07 +00004718 added.
4719
Christian Heimesc94e2b52008-01-14 04:13:37 +00004720- sys.float_info / PyFloat_GetInfo: The floating point information
4721 object was converted from a dict to a specialized structseq object.
4722
Georg Brandl3ee81df2008-05-17 18:14:43 +00004723- Patch #1816: Added sys.flags structseq. It exposes the status of
4724 most command line arguments and PYTHON* environment variables.
Christian Heimesf31b69f2008-01-14 03:42:48 +00004725
Georg Brandl3ee81df2008-05-17 18:14:43 +00004726- Objects/structseq.c: Implemented new structseq representation. The
4727 patch makes structseqs (e.g. the return value of os.stat) more
4728 readable.
Christian Heimes9c201962008-01-14 03:33:52 +00004729
Georg Brandl3ee81df2008-05-17 18:14:43 +00004730- Patch #1700288: added a type attribute cache that caches method

4739 envvar and sys.dont_write_bytecode attribute. All these can be set
4740 to forbid Python to attempt to write compiled bytecode files.
Georg Brandl2da0fce2008-01-07 17:09:35 +00004741
Georg Brandl3ee81df2008-05-17 18:14:43 +00004742- Improve some exception messages when Windows fails to load an
4743 extension module. Now we get for example '%1 is not a valid Win32
4744 application' instead of 'error code 193'.
Amaury Forgeot d'Arce0b76952008-01-04 02:04:15 +00004745

Christian Heimes0a8143f2007-12-18 23:22:54 +00004751- Issue #1635: Platform independent creation and representation of NaN
Georg Brandl3ee81df2008-05-17 18:14:43 +00004752 and INF. float("nan"), float("inf") and float("-inf") now work on
4753 every platform with IEEE 754 semantics.
Christian Heimes0a8143f2007-12-18 23:22:54 +00004754
Georg Brandl3ee81df2008-05-17 18:14:43 +00004755- Compiler now generates simpler and faster code for dictionary
4756 literals. The oparg for BUILD_MAP now indicates an estimated

Georg Brandl3ee81df2008-05-17 18:14:43 +00004806- Issue #1686386: Tuple's tp_repr did not take into account the
4807 possibility of having a self-referential tuple, which is possible
4808 from C code. Nor did object's tp_str consider that a type's tp_str
4809 could do something that could lead to an inifinite recursion.
4810 Py_ReprEnter() and Py_EnterRecursiveCall(), respectively, fixed the
4811 issues.

Georg Brandl3ee81df2008-05-17 18:14:43 +00004827 PyObject_Call() never calling back out to Python code to trigger
4828 recursion depth updates/checks. Required the creation of a static

4878
Guido van Rossum143b5642007-03-23 04:58:42 +00004879- Bug #1683368: The object.__init__() and object.__new__() methods are
4880 now stricter in rejecting excess arguments. The only time when
4881 either allows excess arguments is when it is not overridden and the
4882 other one is. For backwards compatibility, when both are
4883 overridden, it is a deprecation warning (for now; maybe a Py3k
Guido van Rossum234b1ff2007-03-23 19:39:01 +00004884 warning later). Also, type.__init__() insists on the same signature
4885 as supported by type.__new__().

Georg Brandl3ee81df2008-05-17 18:14:43 +00004887- Patch #1675423: PyComplex_AsCComplex() now tries to convert an
4888 object to complex using its __complex__() method before falling back
4889 to the __float__() method. Therefore, the functions in the cmath
4890 module now can operate on objects that define a __complex__()
4891 method.

Georg Brandl7b9c5552007-03-12 14:30:05 +00004909- Bug #1678647: write a newline after printing an exception in any
4910 case, even when converting the value to a string failed.
4911
Georg Brandl871f1bc2007-03-12 13:17:36 +00004912- The dir() function has been extended to call the __dir__() method on
Georg Brandl3ee81df2008-05-17 18:14:43 +00004913 its argument, if it exists. If not, it will work like before. This
4914 allows customizing the output of dir() in the presence of a
4915 __getattr__().

4925 raising a ValueError.
Collin Wintere38051d2007-03-09 20:33:07 +00004926
Georg Brandlaa2321b2007-03-07 00:40:28 +00004927- Patch #703779: unset __file__ in __main__ after running a file. This
Georg Brandl3ee81df2008-05-17 18:14:43 +00004928 makes the filenames the warning module prints much more sensible
4929 when a PYTHONSTARTUP file is used.

4944
Georg Brandl3ee81df2008-05-17 18:14:43 +00004945- When printing an unraisable error, don't print exceptions. before

5513
Georg Brandl92a6bae2007-03-13 17:43:32 +00005514- Patch #1603688: ConfigParser.SafeConfigParser now checks values that
Georg Brandl3ee81df2008-05-17 18:14:43 +00005515 are set for invalid interpolation sequences that would lead to

5572 TestCase and TestSuite subclasses (not instances) are no longer
5573 accepted in TestSuite.addTest(). This should cause no

5575 -- the failure just occurred later, with a more cumbersome
5576 exception.

5860 Fenner.
Gregory P. Smith2b3ba582008-01-17 08:03:17 +00005861
Georg Brandl3ee81df2008-05-17 18:14:43 +00005862- Issue #1339: The smtplib.SMTP class has been refactored a bit such
Gregory P. Smithbde4ae42008-01-17 08:35:49 +00005863 that the SMTP.starttls() caller no longer needs to call ehlo()
5864 beforehand. SMTP.starttls() now raises an exception of the server
Georg Brandl3ee81df2008-05-17 18:14:43 +00005865 does not claim to support starttls. Adds the
5866 SMTP.ehlo_or_helo_if_needed() method. Patch contributed by Bill

5947 complex, tuple, list, dict, set, and frozenset. Formerly, it would

Raymond Hettinger12e94202007-11-07 01:13:09 +00005950

Georg Brandl3ee81df2008-05-17 18:14:43 +00005965 time so that opening a database previously created with the DB_DUP
5966 or DB_DUPSORT flag set will keep the proper behavior on subsequent
5967 opens. Specifically: dictionary assignment to a DB object will
5968 replace all values for a given key when the database allows

Raymond Hettingerdc1d1ba2007-11-07 02:45:46 +00006249- Add a FAST_LOOPS build option that speeds-up looping by trading away
Georg Brandl3ee81df2008-05-17 18:14:43 +00006250 periodic threadstate and signal checking in tight loops. By
6251 default, this option is turned-off. It should only be enabled in
6252 debugged, performance critical applications.

6304
Georg Brandl3ee81df2008-05-17 18:14:43 +00006305- Unified naming convention for free lists and their limits. All free
6306 lists in Object/ are named ``free_list``, the counter ``numfree``
6307 and the upper limit is a macro ``PyName_MAXFREELIST`` inside an
6308 #ifndef block.
Christian Heimes5b970ad2008-02-06 13:33:44 +00006309
Georg Brandl3ee81df2008-05-17 18:14:43 +00006310- ``PySet_Add()`` can now modify a newly created frozenset. Similarly
6311 to ``PyTuple_SetItem``, it can be used to populate a brand new
6312 frozenset; but it does not steal a reference to the added item.

6324
Georg Brandl3ee81df2008-05-17 18:14:43 +00006325- Issue #1521: On 64bit platforms, using PyArgs_ParseTuple with the t#
6326 of w# format code incorrectly truncated the length to an int, even
6327 when PY_SSIZE_T_CLEAN is set. The str.decode method used to return
6328 incorrect results with huge strings.
Georg Brandl6caad7d2008-01-26 14:19:22 +00006329

Georg Brandl3ee81df2008-05-17 18:14:43 +00006354- ``PyImport_Import`` and ``PyImport_ImportModule`` now always do
6355 absolute imports. In earlier versions they might have used relative
6356 imports under some conditions.

Georg Brandl3ee81df2008-05-17 18:14:43 +00006358- Added case insensitive comparison methods ``PyOS_stricmp(char*,
6359 char*)`` and ``PyOS_strnicmp(char*, char*, Py_ssize_t)``.
Christian Heimes000a0742008-01-03 22:16:32 +00006360
Georg Brandl3ee81df2008-05-17 18:14:43 +00006361- Bug #1542693: remove semi-colon at end of PyImport_ImportModuleEx
