Georg Brandlfee0f442010-05-22 21:26:21 +0000582- Issue #8451: Syslog module now uses basename(sys.argv[0]) instead of the
583 string "python" as the *ident*. openlog() arguments are all optional and
584 keywords.

Mark Dickinsond2f3e3f2010-05-05 22:23:58 +0000664 (Optimization was unintentionally turned on in gcc --with-pydebug builds in

687-----------------
688
Philip Jenveyaebbaeb2010-04-06 23:24:45 +0000689- Issue #7301: Add environment variable $PYTHONWARNINGS.
690
Benjamin Peterson3a1dfa22010-04-06 21:50:00 +0000691- Issue #8329: Don't return the same lists from select.select when no fds are
692 changed.
693
Georg Brandlfee0f442010-05-22 21:26:21 +0000694- Issue #8259: ``1L << (2**31)`` no longer produces an 'outrageous shift error'
Mark Dickinson82791672010-04-06 16:47:55 +0000695 on 64-bit machines. The shift count for either left or right shift is
696 permitted to be up to sys.maxsize.
697
Benjamin Peterson4ceeeb02010-04-03 22:48:51 +0000698- Ensure that tokenization of identifiers is not affected by locale.

703
Georg Brandlfee0f442010-05-22 21:26:21 +0000704- Issue #7994: Issue a PendingDeprecationWarning if object.__format__ is called
705 with a non-empty format string. This is an effort to future-proof user
706 code. If a derived class does not currently implement __format__ but later
707 adds its own __format__, it would most likely break user code that had
708 supplied a format string. This will be changed to a DeprecationWaring in
709 Python 3.3 and it will be an error in Python 3.4.
Eric Smithd44b2fc2010-04-02 12:30:56 +0000710
Antoine Pitroua57df2c2010-03-31 21:32:15 +0000711- Issue #8268: Old-style classes (not just instances) now support weak

Antoine Pitrouf9de5342010-04-05 21:35:07 +0000736- Issue #8321: Give access to OpenSSL version numbers from the `ssl` module,
Georg Brandlfee0f442010-05-22 21:26:21 +0000737 using the new attributes `ssl.OPENSSL_VERSION`, `ssl.OPENSSL_VERSION_INFO` and

741
Georg Brandlfee0f442010-05-22 21:26:21 +0000742- Issue #8257: The Decimal construct now accepts a float instance directly,
743 converting that float to a Decimal of equal value:
Mark Dickinson8a950712010-04-03 15:47:46 +0000744
745 >>> Decimal(1.1)

747
Raymond Hettinger34c35b22010-04-03 10:22:00 +0000748- collections.Counter() now supports a subtract() method.
749
Georg Brandlfee0f442010-05-22 21:26:21 +0000750- The functools module now has a total_ordering() class decorator to simplify
751 the specification of rich comparisons.
Raymond Hettingera551f312010-04-04 18:34:45 +0000752
Georg Brandlfee0f442010-05-22 21:26:21 +0000753- The functools module also adds cmp_to_key() as a tool to transition old-style

Georg Brandlfee0f442010-05-22 21:26:21 +0000756- Issue #8294: The Fraction constructor now accepts Decimal and float instances
757 directly.
Mark Dickinson7c63eee2010-04-02 22:27:36 +0000758
Georg Brandlfee0f442010-05-22 21:26:21 +0000759- Issue #7279: Comparisons involving a Decimal signaling NaN now signal
760 InvalidOperation instead of returning False. (Comparisons involving a quiet
761 NaN are unchanged.) Also, Decimal quiet NaNs are now hashable; Decimal
762 signaling NaNs remain unhashable.
Mark Dickinsone096e822010-04-02 10:17:07 +0000763
Georg Brandlfee0f442010-05-22 21:26:21 +0000764- Issue #2531: Comparison operations between floats and Decimal instances now
765 return a result based on the numeric values of the operands; previously they
766 returned an arbitrary result based on the relative ordering of id(float) and
767 id(Decimal).
Mark Dickinson99d80962010-04-02 08:53:22 +0000768
Barry Warsawf7f2d6f2010-03-31 21:07:16 +0000769- Issue #8233: When run as a script, py_compile.py optionally takes a single
Georg Brandlfee0f442010-05-22 21:26:21 +0000770 argument `-` which tells it to read files to compile from stdin. Each line is
771 read on demand and the named file is compiled immediately. (Original patch by
772 Piotr Ożarowski).
Barry Warsawf7f2d6f2010-03-31 21:07:16 +0000773

Georg Brandlfee0f442010-05-22 21:26:21 +0000781- Comparisons using one of <, <=, >, >= between a complex instance and a
782 Fractions instance now raise TypeError instead of returning True/False. This
783 makes Fraction <=> complex comparisons consistent with int <=> complex, float
784 <=> complex, and complex <=> complex comparisons.

893 the set of integer codes for which it was used differed between native packing
894 and standard packing.)

1143 could crash in many places because of the ``PyByteArray_AS_STRING()`` macro
1144 returning NULL. The macro now returns a statically allocated empty string
1145 instead.

Georg Brandlba83f822010-03-14 09:50:54 +00001198 file position when calling `truncate()`. It would previously change the file
1199 position to the given argument, which goes against the tradition of
Antoine Pitrouf3fa0742010-01-31 22:26:04 +00001200 ftruncate() and other truncation APIs. Patch by Pascal Chambon.

1203 class used to represent files stored inside an archive. The new
1204 implementation is significantly faster and can be wrapped in a
1205 ``io.BufferedReader`` object for more speedups. It also solves an issue
1206 where interleaved calls to ``read()`` and ``readline()`` give wrong results.

Georg Brandlba83f822010-03-14 09:50:54 +00001217- Issue #7748: Since unicode values are supported for some metadata options in
1218 Distutils, the DistributionMetadata get_* methods will now return an utf-8
1219 encoded string for them. This ensures that the upload and register commands
1220 send the correct values to PyPI without any error.

Georg Brandlba83f822010-03-14 09:50:54 +00001304 DeprecationWarning when passed a float argument where an integer was expected.
1305 These functions and methods now raise TypeError instead. The majority of the
1306 effects of this change are in the extension modules, but some core functions
1307 and methods are affected: notably the 'chr', 'range' and 'xrange' builtins,
1308 and many unicode/str methods.

Georg Brandlba83f822010-03-14 09:50:54 +00001491- Issue #7117: ``repr(x)`` for a float x returns a result based on the shortest
1492 decimal string that's guaranteed to round back to x under correct rounding
1493 (with round-half-to-even rounding mode). Previously it gave a string based on
1494 rounding x to 17 decimal digits. repr(x) for a complex number behaves
1495 similarly. On platforms where the correctly-rounded strtod and dtoa code is
1496 not supported (see below), repr is unchanged.
Mark Dickinsonb678de82009-11-19 18:41:49 +00001497
Georg Brandlba83f822010-03-14 09:50:54 +00001498- Issue #7117: On almost all platforms: float-to-string and string-to-float
1499 conversions within Python are now correctly rounded. Places these conversions
1500 occur include: str for floats and complex numbers; the float and complex
1501 constructors; old-style and new-style numeric formatting; serialization and
1502 deserialization of floats and complex numbers using marshal, pickle and json;
1503 parsing of float and imaginary literals in Python code; Decimal-to-float
1504 conversion.
Mark Dickinsonb678de82009-11-19 18:41:49 +00001505
Georg Brandlba83f822010-03-14 09:50:54 +00001506 The conversions use a Python-adapted version of David Gay's well-known dtoa.c,
1507 providing correctly-rounded strtod and dtoa C functions. This code is
1508 supported on Windows, and on Unix-like platforms using gcc, icc or suncc as
1509 the C compiler. There may be a small number of platforms on which correct
1510 operation of this code cannot be guaranteed, so the code is not used: notably,
1511 this applies to platforms where the C double format is not IEEE 754 binary64,
1512 and to platforms on x86 hardware where the x87 FPU is set to 64-bit precision
1513 and Python's configure script is unable to determine how to change the FPU
1514 precision. On these platforms conversions use the platform strtod and dtoa,
1515 as before.

Georg Brandlba83f822010-03-14 09:50:54 +00001517- Issue #7117: Backport round implementation from Python 3.x. ``round()`` now
1518 uses the correctly-rounded string <-> float conversions described above (when
1519 available), and so produces correctly rounded results that will display nicely
1520 under the float repr. There are two related small changes: (1) round now
1521 accepts any class with an ``__index__()`` method for its second argument (but
1522 no longer accepts floats for the second argument), and (2) an excessively
1523 large second integer argument (e.g., ``round(1.234, 10**100)``) no longer
1524 raises an exception.

1674 of 12. Previously, the behavior the same but with a default precision of 6.

1903 this code path is really executed because I cannot move to such directory on
1904 win2k)

1930 PyUnicode_DecodeUTF8() once, remember the result and output it in a second

3306
Amaury Forgeot d'Arc05e34492008-09-10 22:04:45 +00003307- Issue #3743: In a few places, PY_FORMAT_SIZE_T was incorrectly used with
3308 PyString_FromFormat or PyErr_Format to display size_t values. The macro
3309 PY_FORMAT_SIZE_T is designed to select the correct format for the OS
3310 ``printf`` function, whereas PyString_FromFormat has an independent
3311 implementation and uses "%zd" on all platforms for size_t values.
3312 This makes a difference on win64, where ``printf`` needs "%Id" to display
3313 64bit values.

Benjamin Peterson97179b02008-09-09 20:55:01 +00003315- Issue #3634: _weakref.ref(Exception).__init__() gave invalid return value on

3319 object; previously an int would be returned for small values. the __long__

Antoine Pitroud4ae97b2008-08-29 18:39:48 +00003330 was correctly parsed but parsing of subsequent arguments failed.
3331
Vinay Sajip35e3b032008-09-01 14:33:59 +00003332- Issue #2534: speed up isinstance() and issubclass() by 50-70%, so as to
Antoine Pitrou0668c622008-08-26 22:42:08 +00003333 match Python 2.5 speed despite the __instancecheck__ / __subclasscheck__
3334 mechanism. In the process, fix a bug where isinstance() and issubclass(),
3335 when given a tuple of classes as second argument, were looking up
3336 __instancecheck__ / __subclasscheck__ on the tuple rather than on each
3337 type object.

Brett Cannon1eaf0742008-09-02 01:25:16 +00003408 warnings.catch_warnings() along with some API cleanup. Expanding the tests
3409 for catch_warnings() also led to an improvement in the raising of a
3410 DeprecationWarning related to warnings.warn_explicit().
3411
Benjamin Peterson973e6c22008-09-01 23:12:58 +00003412- The deprecation warnings for the old camelCase threading API were removed.
3413

3417
Christian Heimes1cc69632008-08-22 20:10:27 +00003418- Fixed two format strings in the _collections module.
3419

Gregory P. Smithd7122032008-09-02 05:36:11 +00003423- Issue #3708: os.urandom no longer goes into an infinite loop when passed a
3424 non-integer floating point number.
3425
Vinay Sajip65d66e12008-09-04 07:31:21 +00003426- Issue #3110: multiprocessing fails to compiel on solaris 10 due to missing

Jesse Noller438195f2009-01-18 21:04:36 +00003432- Issue #4301: Patch the logging module to add processName support, remove
3433 _check_logger_class from multiprocessing.
3434
Amaury Forgeot d'Arc293924b2008-09-02 23:19:56 +00003435- Issue #2975: When compiling several extension modules with Visual Studio 2008
3436 from the same python interpreter, some environment variables would grow
3437 without limit.
3438
Benjamin Peterson37346b22008-08-23 20:27:43 +00003439- Issue #3643: Added a few more checks to _testcapi to prevent segfaults by
3440 exploitation of poor argument checking.
3441
Gerhard Häringef2276b2008-09-12 13:54:06 +00003442- sqlite3: Changed docstring of iterdump() to mark method as "Non-standard".
3443
Gerhard Häring6e1afcf2008-09-12 18:58:57 +00003444- Issue #3103: Reduced globals symbols used by sqlite3 module and made sure all
3445 remaining ones have "pysqlite_" prefix.
3446
Gerhard Häringe6872eb2008-09-12 22:33:22 +00003447- Issue #3846: Release the GIL during sqlite3_prepare calls. This improves

3455 wrapper for warnings.catch_warnings() that makes it easier to check
3456 that expected warning messages are being reported.
3457
Amaury Forgeot d'Arcfeb8cad2008-09-06 20:53:51 +00003458- Issue #3796: Some tests functions were not enabled in test_float.

Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00003476What's New in Python 2.6 beta 3?
3477================================
3478
Barry Warsaw07a4a382008-08-21 01:15:08 +00003479*Release date: 20-Aug-2008*
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00003480
3481Core and Builtins
3482-----------------
3483
Guido van Rossumf8402962008-08-20 15:01:50 +00003484- Issue #1878: Remove Py_TPFLAGS_HAVE_VERSION_TAG from
3485 Py_TPFLAGS_DEFAULT when not building the core. This means 3rd party
3486 extensions do not automatically benefit from the class attribute
3487 cache; they will have to explicitly add Py_TPFLAGS_HAVE_VERSION_TAG
3488 to their tp_flags field if they care. This is a backwards
3489 compatibility feature; in 3.0, all types will use the cache by
3490 default.
3491
Benjamin Petersonf647dc12008-08-20 01:27:30 +00003492- Keyword arguments can now follow starred arguments. (``f(a, *args,
3493 keyword=23)`` is now valid syntax.)
3494
Thomas Heller0ad5ae02008-08-19 19:25:04 +00003495- ctypes function pointers that are COM methods have a boolean True
3496 value again.
3497
Martin v. Löwisf91d46a2008-08-12 14:49:50 +00003498- Issue #3139: Make buffer-interface thread-safe wrt. PyArg_ParseTuple,
3499 by denying s# to parse objects that have a releasebuffer procedure,
3500 and introducing s*.
3501
Georg Brandl1e13ea92008-08-11 09:07:59 +00003502- Issue #3537: Fix an assertion failure when an empty but presized dict
3503 object was stored in the freelist.
3504
Mark Dickinsonb6467572008-08-04 21:30:09 +00003505- Issue #1481296: Make long(float('nan')) and int(float('nan')) raise
3506 ValueError consistently across platforms.
3507
Amaury Forgeot d'Arc39fd6722008-07-31 21:28:03 +00003508- Issue #3479: On platforms where sizeof(int) is smaller than sizeof(long)
3509 (64bit Unix, for example), unichr() would truncate its argument and return
3510 u'\x00' for unichr(2**32). Now it properly raises an OverflowError.
3511
Neal Norwitze7d8be82008-07-31 17:17:14 +00003512- Apply security patches from Apple.
3513
Amaury Forgeot d'Arc246daed2008-07-31 00:42:16 +00003514- Issue #2542: Now that issubclass() may call arbitrary code, ensure that
3515 PyErr_ExceptionMatches returns 0 when an exception occurs there.
3516
Antoine Pitrou92f82162008-07-25 22:22:08 +00003517- Issue #1819: function calls with several named parameters are now on
3518 average 35% faster (as measured by pybench).
3519
Amaury Forgeot d'Arce4921fe2008-07-21 22:00:38 +00003520- Issue #2378: An unexpected UnboundLocalError or NameError could appear when
3521 the python debugger steps into a class statement: the free variables (local
3522 variables defined in an outer scope) would be deleted from the outer scope.
3523
Gregory P. Smith0470bab2008-07-22 04:46:32 +00003524- Issue #2620: Overflow checking when allocating or reallocating memory
3525 was not always being done properly in some python types and extension
3526 modules. PyMem_MALLOC, PyMem_REALLOC, PyMem_NEW and PyMem_RESIZE have
3527 all been updated to perform better checks and places in the code that
3528 would previously leak memory on the error path when such an allocation
3529 failed have been fixed.
3530
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00003531Library
3532-------
3533
Hirokazu Yamamoto838c79f2008-08-20 13:14:07 +00003534- Issue #3612: Added some missing basic types in ctypes.wintypes.
3535
Benjamin Petersone977ad42008-08-20 01:42:01 +00003536- The methods ``is_in_tuple()``, ``is_vararg()``, and ``is_keywordarg()`` of
3537 symtable.Symbol have been deprecated for removal in 3.0 and the next release.
3538
Amaury Forgeot d'Arc351ffb82008-08-18 19:23:47 +00003539- Issue #2234: distutils failed for some versions of the cygwin compiler. The
3540 version reported by these tools does not necessarily follow the python
3541 version numbering scheme, so the module is less strict when parsing it.
3542
Nick Coghlanf70385a2008-08-18 12:42:46 +00003543- Issue #2235: Added Py3k warnings for types which will become unhashable
3544 under the stricter __hash__ inheritance rules in 3.0. Several types
3545 which did not meet the rules for hash invariants and were already
3546 unhashable in 3.0 have now been explicitly flagged as unhashable in
3547 2.6 as well (collections.Mapping, collections.Set, unittest.TestSuite,
3548 xml.dom.minidom.NamedNodeMap, numbers.Number, UserList.UserList)
3549
Brett Cannon88f801d2008-08-18 00:46:22 +00003550- Update __all__ for cookielib, csv, os, urllib2, and weakref to include things
3551 imported into the module but exposed as part of the module's API.
3552
Brett Cannon7b96f072008-08-18 00:41:11 +00003553- Remove an unneeded import of abc.ABCMeta from 'inspect'.
3554
Brett Cannon46225e72008-08-18 00:36:52 +00003555- Remove unneeded imports of 'sys' and 'warnings' from 'io'.

Brett Cannon25c9d6a2008-08-17 22:10:11 +00003557- Remove unneeded imports of 'warnings' from shelve, filecmp, and dummy_thread.
3558
Hirokazu Yamamoto41a81eb2008-08-17 13:10:46 +00003559- Issue #3575: Incremental decoder's decode function now takes bytearray
3560 by using 's*' instead of 't#'.
3561
Mark Dickinson3e4caeb2009-02-21 20:27:01 +00003562- Issue #2222: Fixed reference leak when occurred os.rename()
Hirokazu Yamamoto7f30a682008-08-17 09:46:56 +00003563 fails unicode conversion on 2nd parameter. (windows only)
3564
Georg Brandl222e2082010-08-01 22:27:39 +00003565- Issue #2464: urllib2 now supports a malformation in the URL received
Facundo Batista94f243a2008-08-17 03:38:39 +00003566 in a redirect.
3567
Brett Cannonabe423e2008-08-16 21:47:07 +00003568- Silence the DeprecationWarning raised when importing mimetools in
Brett Cannon721b1452008-08-16 22:00:27 +00003569 BaseHTTPServer, cgi (and rfc822), httplib.
Brett Cannonabe423e2008-08-16 21:47:07 +00003570
Facundo Batistaeb90b782008-08-16 14:44:07 +00003571- Issue #2776: fixed small issue when handling an URL with double slash
3572 after a 302 response in the case of not going through a proxy.
3573
Antoine Pitroub90a8be2008-08-15 21:03:21 +00003574- Issue #2676: in the email package, content-type parsing was hanging on
3575 pathological input because of quadratic or exponential behaviour of a
3576 regular expression.
3577
Antoine Pitrou11ec65d2008-08-14 21:04:30 +00003578- Issue #3476: binary buffered reading through the new "io" library is now
3579 thread-safe.
3580
Brett Cannonbf3157b2008-08-14 05:00:03 +00003581- Silence the DeprecationWarning of rfc822 when it is imported by mimetools
3582 since mimetools itself is deprecated. Because modules are cached, all
3583 subsequent imports of rfc822 will not raise a visible DeprecationWarning.
3584
Antoine Pitrou9fcd4b32008-08-11 17:21:36 +00003585- Issue #3134: shutil referenced undefined WindowsError symbol.
3586
Robert Schuppenies14646332008-08-10 11:01:53 +00003587- Issue #1342811: Fix leak in Tkinter.Menu.delete. Commands associated to
3588 menu entries were not deleted.
3589
Brett Cannon83e81842008-08-09 23:30:55 +00003590- Copied the implementation of reduce() to _functools.reduce() to have a
3591 version that did not raise a DeprecationWarning under -3.
3592
Antoine Pitrou76b8bee2008-08-09 17:27:23 +00003593- Issue #3205: When iterating over a BZ2File fails allocating memory, raise
3594 a MemoryError rather than silently stop the iteration.
3595
Guido van Rossum59ce9012008-08-09 14:55:34 +00003596- Issue #3487: sre "bytecode" validator. Passing invalid "re-bytecode"
3597 to _sre.compile() will now be rejected. This should not affect anybody
3598 since the re.compile() function never generates invalid re-bytecode.
3599
Skip Montanaroa032bf42008-08-08 22:52:51 +00003600- Issue #3436: Make csv.DictReader's fieldnames attribute a property so that
3601 upon first access it can be automatically initialized from the csv file if
3602 it wasn't initialized during instantiation.
3603
Brett Cannon3aa2a492008-08-06 22:28:09 +00003604- Issue #2338: Create imp.reload() to help with transitioning to Python 3.0 as
3605 the reload() built-in has been removed.
3606
Brett Cannon7e30b672008-08-04 21:52:25 +00003607- Changed code in the following modules/packages to remove warnings raised
Brett Cannonc1b76e42008-08-09 23:06:16 +00003608 while running under the ``-3`` flag: aifc, asynchat, asyncore, bdb, bsddb,

Antoine Pitroude781a42008-08-09 12:43:23 +00003619 asking for a specific length. This problem only affected files opened
3620 using the new "io" module, not the built-in open() function.
Benjamin Peterson01a24322008-07-28 23:35:27 +00003621

3646 file name rather than a ZipInfo instance, so files are extracted with
3647 mode 0600 rather than 000 under Unix.
3648
Gregory P. Smitha36f8fe2008-08-04 00:13:29 +00003649- Issue #1857: subprocess.Popen.poll gained an additional _deadstate keyword
3650 argument in python 2.5, this broke code that subclassed Popen to include its
3651 own poll method. Fixed my moving _deadstate to an _internal_poll method.

3666 regarding lack of coverage of new-style classes have also been
3667 removed, since the coverage is now fairly reasonable.

3677
Georg Brandl3e483f62008-07-16 22:57:41 +00003678- Issue #3156: Fix inconsistent behavior of the bytearray type: all
3679 its methods now allow for items objects that can be converted to
3680 an integer using operator.index().
3681
Mark Dickinson64b7e502008-07-16 09:40:03 +00003682- Issue #3360: Fix incorrect parsing of '020000000000.0', which
3683 produced a ValueError instead of giving the correct float.
3684
Eric Smitha5fa5a22008-07-16 00:11:49 +00003685- Issue #3083: Add alternate (#) formatting for bin, oct, hex output

3690 numbers to and from hexadecimal strings, respectively.
3691
Nick Coghlan6d6bd442008-07-15 15:40:22 +00003692- Issue #2235: __hash__ is once again inherited by default. To allow
3693 collections.Hashable to remain meaningful in the presence of the
3694 default hash implementation (object.__hash__), it is now possible
3695 to explicit block inheritance of hash by setting __hash__=None at
3696 the Python level, or tp_hash=PyObject_HashNotImplemented at the C
3697 level.
3698
Nick Coghlanb028f502008-07-13 14:52:36 +00003699- Issue #3221: Issue a RuntimeWarning instead of raising SystemError if
3700 the parent module cannot be found while performing an absolute import.
3701 This means that an incorrectly defined __package__ attribute will
3702 now only prevent relative imports in that module rather than causing
3703 all imports from that module to fail.
3704
Nick Coghlan14ff9942008-07-08 14:21:42 +00003705- Issue #2517: Allow unicode messages in Exceptions again by correctly

3716
Mark Dickinson1ec2fcd2008-06-20 14:53:43 +00003717- Issue #3004: Minor change to slice.indices(): the start and stop
3718 arguments are now treated identically, making the behaviour easier
3719 to describe and understand. For example, slice(None, -10,
3720 1).indices(9) now returns (0, 0, 1) instead of (0, -1, 1), and
3721 slice(None, 10, -1).indices(10) returns (9, 9, -1) instead of (9,
3722 10, -1).

3765 both unnecessary (HTTP allows text content to be sent in several forms) and
Andrew M. Kuchlingcc3f2b12008-07-10 14:43:31 +00003766 wrong because the actual transmitted size could differ from the

Georg Brandl5cc774e2008-06-11 20:28:06 +00004176 PPC64 and x86_64 support in one binary).
Ronald Oussoren5640ce22008-06-05 12:58:24 +00004177
4178 This is controlled by the configure argument ``--with-universal-archs``:

4181
4182 - ``--with-universal-archs=32-bit``: install 2-way universal, 32-bit (the default)
4183
4184 - ``--with-universal-archs=64-bit``: install 2-way universal, 64-bit

4225 two handlers that derive the same default base class.

Christian Heimese74c8f22008-04-19 02:23:57 +00004227- Added kill, terminate and send_signal(sig) to subprocess.Popen.

Georg Brandl3ee81df2008-05-17 18:14:43 +00004238- Issue #1631171: Re-implement the 'warnings' module in C (the
4239 original Python code has been kept as backup). This will allow for
4240 using the 'warning's machinery in such places as the parser where
4241 use of pure Python code is not possible. Both the ``showarning()``
4242 and ``formatwarning()`` gain an optional 'line' argument which is
4243 not called by default for backwards-compatibility reasons. Setting
4244 ``warnings.showwarning()`` to an implementation that lacks support

Georg Brandl3ee81df2008-05-17 18:14:43 +00004308- Issue #2550: The approach used by client/server code for obtaining
4309 ports to listen on in network-oriented tests has been refined in an
4310 effort to facilitate running multiple instances of the entire
4311 regression test suite in parallel without issue.
4312 test_support.bind_port() has been fixed such that it will always
4313 return a unique port -- which wasn't always the case with the
4314 previous implementation, especially if socket options had been set
4315 that affected address reuse (i.e. SO_REUSEADDR, SO_REUSEPORT). The
4316 new implementation of bind_port() will actually raise an exception
4317 if it is passed an AF_INET/SOCK_STREAM socket with either the
4318 SO_REUSEADDR or SO_REUSEPORT socket option set. Furthermore, if
4319 available, bind_port() will set the SO_EXCLUSIVEADDRUSE option on
4320 the socket it's been passed. This currently only applies to
4321 Windows. This option prevents any other sockets from binding to the
4322 host/port we've bound to, thus removing the possibility of the
4323 'non-deterministic' behaviour, as Microsoft puts it, that occurs
4324 when a second SOCK_STREAM socket binds and accepts to a host/port
4325 that's already been bound by another socket. The optional preferred
4326 port parameter to bind_port() has been removed. Under no
4327 circumstances should tests be hard coding ports!
4328
4329 test_support.find_unused_port() has also been introduced, which will
4330 pass a temporary socket object to bind_port() in order to obtain an
4331 unused port. The temporary socket object is then closed and
4332 deleted, and the port is returned. This method should only be used
4333 for obtaining an unused port in order to pass to an external program
4334 (i.e. the -accept [port] argument to openssl's s_server mode) or as
4335 a parameter to a server-oriented class that doesn't give you direct
4336 access to the underlying socket used.
4337
4338 Finally, test_support.HOST has been introduced, which should be used
4339 for the host argument of any relevant socket calls (i.e. bind and
4340 connect).
Trent Nelsone41b0062008-04-08 23:47:30 +00004341
4342 The following tests were updated to following the new conventions:
Georg Brandl3ee81df2008-05-17 18:14:43 +00004343 test_socket, test_smtplib, test_asyncore, test_ssl, test_httplib,
Trent Nelsone41b0062008-04-08 23:47:30 +00004344 test_poplib, test_ftplib, test_telnetlib, test_socketserver,
4345 test_asynchat and test_socket_ssl.
4346
Georg Brandl3ee81df2008-05-17 18:14:43 +00004347 It is now possible for multiple instances of the regression test
4348 suite to run in parallel without issue.

Georg Brandl3ee81df2008-05-17 18:14:43 +00004514- Issue #1202: zlib.crc32 and zlib.adler32 no longer return different
4515 values on 32-bit vs. 64-bit python interpreters. Both were correct,
4516 but they now both return a signed integer object for consistency.

Eric Smitha73fbe72008-02-23 03:09:44 +00004627- Added the future_builtins module, which contains hex() and oct().
4628 These are the PEP 3127 version of these functions, designed to be
4629 compatible with the hex() and oct() builtins from Python 3.0. They
4630 differ slightly in their output formats from the existing, unchanged
4631 Python 2.6 builtins. The expected usage of the future_builtins
4632 module is:
4633 from future_builtins import hex, oct
4634
Eric Smith7ef40bf2008-02-20 23:34:22 +00004635- Issue #1600: Modifed PyOS_ascii_formatd to use at most 2 digit
4636 exponents for exponents with absolute value < 100. Follows C99
4637 standard. This is a change on Windows, which would use 3 digits.
4638 Also, added 'n' to the formats that PyOS_ascii_formatd understands,
4639 so that any alterations it does to the resulting string will be
4640 available in stringlib/formatter.h (for float.__format__).
4641
Eric Smith5a3c1352008-02-19 13:21:56 +00004642- Implemented PEP 3101, Advanced String Formatting. This adds a new
4643 builtin format(); a format() method for str and unicode; a
4644 __format__() method to object, str, unicode, int, long, float, and
4645 datetime; the class string.Formatter; and the C API
4646 PyObject_Format().
4647
Georg Brandl3ee81df2008-05-17 18:14:43 +00004648- Fixed several potential crashes, all caused by specially crafted
4649 __del__ methods exploiting objects in temporarily inconsistent
4650 state.
Amaury Forgeot d'Arc632fad32008-02-16 20:55:24 +00004651
Vinay Sajipb7edfc42008-04-02 21:10:23 +00004652- Issue #2115: Important speedup in setting __slot__ attributes. Also
Georg Brandl3ee81df2008-05-17 18:14:43 +00004653 prevent a possible crash: an Abstract Base Class would try to access
4654 a slot on a registered virtual subclass.
Amaury Forgeot d'Arc60d6c7f2008-02-15 21:22:45 +00004655
Georg Brandl3ee81df2008-05-17 18:14:43 +00004656- Fixed repr() and str() of complex numbers with infinity or nan as
4657 real or imaginary part.

Georg Brandl3ee81df2008-05-17 18:14:43 +00004659- Clear all free lists during a gc.collect() of the highest generation
4660 in order to allow pymalloc to free more arenas. Python may give back
4661 memory to the OS earlier.
Christian Heimes3b718a72008-02-14 12:47:33 +00004662
Georg Brandl3ee81df2008-05-17 18:14:43 +00004663- Issue #2045: Fix an infinite recursion triggered when printing a
4664 subclass of collections.defaultdict, if its default_factory is set
4665 to a bound method.
Amaury Forgeot d'Arcb01aa432008-02-08 00:56:02 +00004666
Christian Heimesf75dbef2008-02-08 00:11:31 +00004667- Fixed a minor memory leak in dictobject.c. The content of the free
4668 list was not freed on interpreter shutdown.
4669
Georg Brandl21e99f42010-03-07 15:23:59 +00004670- Limit free list of method and built-in function objects to 256
Georg Brandl3ee81df2008-05-17 18:14:43 +00004671 entries each.
Christian Heimes6075a822008-02-06 12:44:34 +00004672
Georg Brandl3ee81df2008-05-17 18:14:43 +00004673- Patch #1953: Added ``sys._compact_freelists()`` and the C API
4674 functions ``PyInt_CompactFreeList`` and ``PyFloat_CompactFreeList``
Christian Heimes422051a2008-02-04 18:00:12 +00004675 to compact the internal free lists of pre-allocted ints and floats.
4676
Georg Brandl3ee81df2008-05-17 18:14:43 +00004677- Issue #1983: Fixed return type of fork(), fork1() and forkpty()
4678 calls. Python expected the return type int but the fork familie
4679 returns pi_t.
Christian Heimes951cc0f2008-01-31 23:08:23 +00004680
Georg Brandl3ee81df2008-05-17 18:14:43 +00004681- Issue #1678380: Fix a bug that identifies 0j and -0j when they
4682 appear in the same code unit.

4691 the internal lookup cache for ref leak tests.
Christian Heimes908caac2008-01-27 23:34:59 +00004692
Georg Brandl3ee81df2008-05-17 18:14:43 +00004693- Patch #1473257: generator objects gain a gi_code attribute. This is
4694 the same object as the func_code attribute of the function that
4695 produced the generator.
Georg Brandl0cdf9a32008-01-26 14:14:20 +00004696
Georg Brandl3ee81df2008-05-17 18:14:43 +00004697- Issue #1920: "while 0" statements were completely removed by the
4698 compiler, even in the presence of an "else" clause, which is
4699 supposed to be run when the condition is false. Now the compiler
4700 correctly emits bytecode for the "else" suite.
Amaury Forgeot d'Arc31eaafe2008-01-24 22:59:25 +00004701
Guido van Rossumeead05f2008-01-24 18:21:02 +00004702- A few crashers fixed: weakref_in_del.py (issue #1377858);
4703 loosing_dict_ref.py (issue #1303614, test67.py);
4704 borrowed_ref_[34].py (not in tracker).
4705
Vinay Sajipd7cf32e2008-01-24 12:43:33 +00004706- Issue #1069410: The "can't load dll" message box on Windows is
Christian Heimesb2302ba2008-01-23 17:15:06 +00004707 suppressed while an extension is loaded by calling SetErrorMode in
4708 dynload_win.c. The error is still reported properly.
4709
Georg Brandl3ee81df2008-05-17 18:14:43 +00004710- Issue #1915: Python compiles with --enable-unicode=no again. However
Christian Heimes082c9b02008-01-23 14:20:50 +00004711 several extension methods and modules do not work without unicode
4712 support.
4713
Georg Brandl26543b12008-01-21 18:36:51 +00004714- Issue #1882: when compiling code from a string, encoding cookies in the
4715 second line of code were not always recognized correctly.
4716
Georg Brandl14404b62008-01-19 19:27:05 +00004717- Issue #1679: "0x" was taken as a valid integer literal.
4718
Georg Brandl6caad7d2008-01-26 14:19:22 +00004719- Issue #1865: ``bytes`` as an alias for ``str`` and b"" as an alias "" were
Christian Heimes288e89a2008-01-18 18:24:07 +00004720 added.
4721
Christian Heimesc94e2b52008-01-14 04:13:37 +00004722- sys.float_info / PyFloat_GetInfo: The floating point information
4723 object was converted from a dict to a specialized structseq object.
4724
Georg Brandl3ee81df2008-05-17 18:14:43 +00004725- Patch #1816: Added sys.flags structseq. It exposes the status of
4726 most command line arguments and PYTHON* environment variables.
Christian Heimesf31b69f2008-01-14 03:42:48 +00004727
Georg Brandl3ee81df2008-05-17 18:14:43 +00004728- Objects/structseq.c: Implemented new structseq representation. The
4729 patch makes structseqs (e.g. the return value of os.stat) more
4730 readable.
Christian Heimes9c201962008-01-14 03:33:52 +00004731
Georg Brandl3ee81df2008-05-17 18:14:43 +00004732- Patch #1700288: added a type attribute cache that caches method

Georg Brandl3ee81df2008-05-17 18:14:43 +00004744- Improve some exception messages when Windows fails to load an
4745 extension module. Now we get for example '%1 is not a valid Win32
4746 application' instead of 'error code 193'.

Georg Brandl3ee81df2008-05-17 18:14:43 +00004805 smaller than LONG_MAX. Formerly, it raised an OverflowError. Now,
4806 automatically shifts from ints to longs.

Georg Brandl3ee81df2008-05-17 18:14:43 +00004808- Issue #1686386: Tuple's tp_repr did not take into account the
4809 possibility of having a self-referential tuple, which is possible
4810 from C code. Nor did object's tp_str consider that a type's tp_str
4811 could do something that could lead to an inifinite recursion.
4812 Py_ReprEnter() and Py_EnterRecursiveCall(), respectively, fixed the
4813 issues.

4816 'print' statement to write to a file since the GIL was not released
4817 as needed. Now PyObject_Print() does the right thing along with
4818 various tp_print implementations of the built-in types and those in
4819 the collections module.

Georg Brandl3ee81df2008-05-17 18:14:43 +00004829 PyObject_Call() never calling back out to Python code to trigger
4830 recursion depth updates/checks. Required the creation of a static

4880
Guido van Rossum143b5642007-03-23 04:58:42 +00004881- Bug #1683368: The object.__init__() and object.__new__() methods are
4882 now stricter in rejecting excess arguments. The only time when
4883 either allows excess arguments is when it is not overridden and the
4884 other one is. For backwards compatibility, when both are
4885 overridden, it is a deprecation warning (for now; maybe a Py3k
Guido van Rossum234b1ff2007-03-23 19:39:01 +00004886 warning later). Also, type.__init__() insists on the same signature
4887 as supported by type.__new__().

Georg Brandl3ee81df2008-05-17 18:14:43 +00004889- Patch #1675423: PyComplex_AsCComplex() now tries to convert an
4890 object to complex using its __complex__() method before falling back
4891 to the __float__() method. Therefore, the functions in the cmath
4892 module now can operate on objects that define a __complex__()
4893 method.

Georg Brandl7b9c5552007-03-12 14:30:05 +00004911- Bug #1678647: write a newline after printing an exception in any
4912 case, even when converting the value to a string failed.
4913
Georg Brandl871f1bc2007-03-12 13:17:36 +00004914- The dir() function has been extended to call the __dir__() method on
Georg Brandl3ee81df2008-05-17 18:14:43 +00004915 its argument, if it exists. If not, it will work like before. This
4916 allows customizing the output of dir() in the presence of a
4917 __getattr__().

4927 raising a ValueError.
Collin Wintere38051d2007-03-09 20:33:07 +00004928
Georg Brandlaa2321b2007-03-07 00:40:28 +00004929- Patch #703779: unset __file__ in __main__ after running a file. This
Georg Brandl3ee81df2008-05-17 18:14:43 +00004930 makes the filenames the warning module prints much more sensible
4931 when a PYTHONSTARTUP file is used.

4946
Georg Brandl3ee81df2008-05-17 18:14:43 +00004947- When printing an unraisable error, don't print exceptions. before

5515
Georg Brandl92a6bae2007-03-13 17:43:32 +00005516- Patch #1603688: ConfigParser.SafeConfigParser now checks values that
Georg Brandl3ee81df2008-05-17 18:14:43 +00005517 are set for invalid interpolation sequences that would lead to
5518 errors on reading back those values.

5572

5574 TestCase and TestSuite subclasses (not instances) are no longer
5575 accepted in TestSuite.addTest(). This should cause no
5576 incompatibility since it never made sense with ordinary subclasses
5577 -- the failure just occurred later, with a more cumbersome
5578 exception.

Gregory P. Smithbde4ae42008-01-17 08:35:49 +00005865 that the SMTP.starttls() caller no longer needs to call ehlo()

Georg Brandl3ee81df2008-05-17 18:14:43 +00005867 does not claim to support starttls. Adds the
5868 SMTP.ehlo_or_helo_if_needed() method. Patch contributed by Bill

Georg Brandl3ee81df2008-05-17 18:14:43 +00005967 time so that opening a database previously created with the DB_DUP
5968 or DB_DUPSORT flag set will keep the proper behavior on subsequent
5969 opens. Specifically: dictionary assignment to a DB object will

Raymond Hettingerdc1d1ba2007-11-07 02:45:46 +00006251- Add a FAST_LOOPS build option that speeds-up looping by trading away
Georg Brandl3ee81df2008-05-17 18:14:43 +00006252 periodic threadstate and signal checking in tight loops. By
6253 default, this option is turned-off. It should only be enabled in
6254 debugged, performance critical applications.

Georg Brandl3ee81df2008-05-17 18:14:43 +00006312- ``PySet_Add()`` can now modify a newly created frozenset. Similarly
6313 to ``PyTuple_SetItem``, it can be used to populate a brand new

6326
Georg Brandl3ee81df2008-05-17 18:14:43 +00006327- Issue #1521: On 64bit platforms, using PyArgs_ParseTuple with the t#
6328 of w# format code incorrectly truncated the length to an int, even
6329 when PY_SSIZE_T_CLEAN is set. The str.decode method used to return
6330 incorrect results with huge strings.

Georg Brandl3ee81df2008-05-17 18:14:43 +00006360- Added case insensitive comparison methods ``PyOS_stricmp(char*,
6361 char*)`` and ``PyOS_strnicmp(char*, char*, Py_ssize_t)``.
