Ned Deily0d0ea482012-02-10 12:59:06 +0100541- Issue #13590: On OS X 10.7 and 10.6 with Xcode 4.2, building
542 Distutils-based packages with C extension modules may fail because
543 Apple has removed gcc-4.2, the version used to build python.org
544 64-bit/32-bit Pythons. If the user does not explicitly override
545 the default C compiler by setting the CC environment variable,
546 Distutils will now attempt to compile extension modules with clang
547 if gcc-4.2 is required but not found. Also as a convenience, if
548 the user does explicitly set CC, substitute its value as the default
549 compiler in the Distutils LDSHARED configuration variable for OS X.
550 (Note, the python.org 32-bit-only Pythons use gcc-4.0 and the 10.4u
551 SDK, neither of which are available in Xcode 4. This change does not
552 attempt to override settings to support their use with Xcode 4.)

Ned Deily87e82bb2011-06-28 19:52:59 -0700825- Issue #9516: On Mac OS X, change Distutils to no longer globally attempt to
826 check or set the MACOSX_DEPLOYMENT_TARGET environment variable for the
827 interpreter process. This could cause failures in non-Distutils subprocesses
828 and was unreliable since tests or user programs could modify the interpreter
829 environment after Distutils set it. Instead, have Distutils set the the
830 deployment target only in the environment of each build subprocess. It is
831 still possible to globally override the default by setting
832 MACOSX_DEPLOYMENT_TARGET before launching the interpreter; its value must be
833 greater or equal to the default value, the value with which the interpreter
834 was built.

864 the ticker doesn't have to wind down to zero from the old starting point
865 before the new interval takes effect. And if the user increases the
866 interval, it makes sure the new limit takes effect right away rather have an
867 early task switch before recognizing the new interval.

Raymond Hettinger20397532010-09-12 02:11:45 +00001818- Issue #9825: removed __del__ from the definition of collections.OrderedDict.
1819 This prevents user-created self-referencing ordered dictionaries from
1820 becoming permanently uncollectable GC garbage. The downside is that
1821 removing __del__ means that the internal doubly-linked list has to wait for
1822 GC collection rather than freeing memory immediately when the refcnt drops
1823 to zero.

Mark Dickinsond2f3e3f2010-05-05 22:23:58 +00002643 (Optimization was unintentionally turned on in gcc --with-pydebug builds in

2665Core and Builtins
2666-----------------
2667
Philip Jenveyaebbaeb2010-04-06 23:24:45 +00002668- Issue #7301: Add environment variable $PYTHONWARNINGS.
2669
Benjamin Peterson3a1dfa22010-04-06 21:50:00 +00002670- Issue #8329: Don't return the same lists from select.select when no fds are
2671 changed.
2672
Georg Brandlfee0f442010-05-22 21:26:21 +00002673- Issue #8259: ``1L << (2**31)`` no longer produces an 'outrageous shift error'
Mark Dickinson82791672010-04-06 16:47:55 +00002674 on 64-bit machines. The shift count for either left or right shift is
2675 permitted to be up to sys.maxsize.
2676
Benjamin Peterson4ceeeb02010-04-03 22:48:51 +00002677- Ensure that tokenization of identifiers is not affected by locale.
2678
Georg Brandlfee0f442010-05-22 21:26:21 +00002679- Issue #1222585: Added LDCXXSHARED for C++ support. Patch by Arfrever.
Tarek Ziadé00002952010-04-03 08:37:59 +00002680
Benjamin Peterson1c7c11e2010-04-03 01:28:57 +00002681- Raise a TypeError when trying to delete a T_STRING_INPLACE struct member.
2682
Georg Brandlfee0f442010-05-22 21:26:21 +00002683- Issue #7994: Issue a PendingDeprecationWarning if object.__format__ is called
2684 with a non-empty format string. This is an effort to future-proof user
2685 code. If a derived class does not currently implement __format__ but later
2686 adds its own __format__, it would most likely break user code that had
Antoine Pitrou01a196a2011-01-02 20:05:11 +00002687 supplied a format string. This will be changed to a DeprecationWarning in
Georg Brandlfee0f442010-05-22 21:26:21 +00002688 Python 3.3 and it will be an error in Python 3.4.
Eric Smithd44b2fc2010-04-02 12:30:56 +00002689
Antoine Pitroua57df2c2010-03-31 21:32:15 +00002690- Issue #8268: Old-style classes (not just instances) now support weak

Victor Stinner66644262010-03-10 22:30:19 +00002703- Issue #3137: Don't ignore errors at startup, especially a keyboard interrupt
Georg Brandlba83f822010-03-14 09:50:54 +00002704 (SIGINT). If an error occurs while importing the site module, the error is

2720
Georg Brandlfee0f442010-05-22 21:26:21 +00002721- Issue #8257: The Decimal construct now accepts a float instance directly,
2722 converting that float to a Decimal of equal value:
Mark Dickinson8a950712010-04-03 15:47:46 +00002723
2724 >>> Decimal(1.1)
2725 Decimal('1.100000000000000088817841970012523233890533447265625')
2726
Raymond Hettinger34c35b22010-04-03 10:22:00 +00002727- collections.Counter() now supports a subtract() method.
2728
Georg Brandlfee0f442010-05-22 21:26:21 +00002729- The functools module now has a total_ordering() class decorator to simplify
2730 the specification of rich comparisons.

Georg Brandlfee0f442010-05-22 21:26:21 +00002738- Issue #7279: Comparisons involving a Decimal signaling NaN now signal
2739 InvalidOperation instead of returning False. (Comparisons involving a quiet
2740 NaN are unchanged.) Also, Decimal quiet NaNs are now hashable; Decimal
2741 signaling NaNs remain unhashable.
Mark Dickinsone096e822010-04-02 10:17:07 +00002742
Georg Brandlfee0f442010-05-22 21:26:21 +00002743- Issue #2531: Comparison operations between floats and Decimal instances now
2744 return a result based on the numeric values of the operands; previously they
2745 returned an arbitrary result based on the relative ordering of id(float) and
2746 id(Decimal).
Mark Dickinson99d80962010-04-02 08:53:22 +00002747
Barry Warsawf7f2d6f2010-03-31 21:07:16 +00002748- Issue #8233: When run as a script, py_compile.py optionally takes a single
Georg Brandlfee0f442010-05-22 21:26:21 +00002749 argument `-` which tells it to read files to compile from stdin. Each line is
2750 read on demand and the named file is compiled immediately. (Original patch by
2751 Piotr Ożarowski).

Florent Xicluna58b65662010-03-30 16:29:03 +00002756- Backwards incompatible change: Unicode codepoints line tabulation (0x0B) and
2757 form feed (0x0C) are now considered linebreaks, as specified in Unicode
Georg Brandlfee0f442010-05-22 21:26:21 +00002758 Standard Annex #14. See issue #7643. http://www.unicode.org/reports/tr14/
Florent Xicluna22b24382010-03-30 08:24:06 +00002759
Georg Brandlfee0f442010-05-22 21:26:21 +00002760- Comparisons using one of <, <=, >, >= between a complex instance and a
2761 Fractions instance now raise TypeError instead of returning True/False. This
2762 makes Fraction <=> complex comparisons consistent with int <=> complex, float
2763 <=> complex, and complex <=> complex comparisons.

2872 the set of integer codes for which it was used differed between native packing
2873 and standard packing.)

3126 could crash in many places because of the ``PyByteArray_AS_STRING()`` macro
3127 returning NULL. The macro now returns a statically allocated empty string
3128 instead.

Georg Brandlba83f822010-03-14 09:50:54 +00003181 file position when calling `truncate()`. It would previously change the file
3182 position to the given argument, which goes against the tradition of
Antoine Pitrouf3fa0742010-01-31 22:26:04 +00003183 ftruncate() and other truncation APIs. Patch by Pascal Chambon.

3186 class used to represent files stored inside an archive. The new
3187 implementation is significantly faster and can be wrapped in a
3188 ``io.BufferedReader`` object for more speedups. It also solves an issue
3189 where interleaved calls to ``read()`` and ``readline()`` give wrong results.

Georg Brandlba83f822010-03-14 09:50:54 +00003200- Issue #7748: Since unicode values are supported for some metadata options in
3201 Distutils, the DistributionMetadata get_* methods will now return an utf-8
3202 encoded string for them. This ensures that the upload and register commands
3203 send the correct values to PyPI without any error.

Mark Dickinson1b34d252010-01-01 17:27:30 +00003286- Issue #5080: A number of functions and methods previously produced a
Georg Brandlba83f822010-03-14 09:50:54 +00003287 DeprecationWarning when passed a float argument where an integer was expected.
3288 These functions and methods now raise TypeError instead. The majority of the
3289 effects of this change are in the extension modules, but some core functions
3290 and methods are affected: notably the 'chr', 'range' and 'xrange' builtins,
3291 and many unicode/str methods.

Georg Brandlba83f822010-03-14 09:50:54 +00003474- Issue #7117: ``repr(x)`` for a float x returns a result based on the shortest
3475 decimal string that's guaranteed to round back to x under correct rounding
3476 (with round-half-to-even rounding mode). Previously it gave a string based on
3477 rounding x to 17 decimal digits. repr(x) for a complex number behaves
3478 similarly. On platforms where the correctly-rounded strtod and dtoa code is
3479 not supported (see below), repr is unchanged.
Mark Dickinsonb678de82009-11-19 18:41:49 +00003480
Georg Brandlba83f822010-03-14 09:50:54 +00003481- Issue #7117: On almost all platforms: float-to-string and string-to-float
3482 conversions within Python are now correctly rounded. Places these conversions
3483 occur include: str for floats and complex numbers; the float and complex
3484 constructors; old-style and new-style numeric formatting; serialization and
3485 deserialization of floats and complex numbers using marshal, pickle and json;
3486 parsing of float and imaginary literals in Python code; Decimal-to-float
3487 conversion.
Mark Dickinsonb678de82009-11-19 18:41:49 +00003488
Georg Brandlba83f822010-03-14 09:50:54 +00003489 The conversions use a Python-adapted version of David Gay's well-known dtoa.c,
3490 providing correctly-rounded strtod and dtoa C functions. This code is
3491 supported on Windows, and on Unix-like platforms using gcc, icc or suncc as
3492 the C compiler. There may be a small number of platforms on which correct
3493 operation of this code cannot be guaranteed, so the code is not used: notably,
3494 this applies to platforms where the C double format is not IEEE 754 binary64,
3495 and to platforms on x86 hardware where the x87 FPU is set to 64-bit precision
3496 and Python's configure script is unable to determine how to change the FPU
3497 precision. On these platforms conversions use the platform strtod and dtoa,
3498 as before.

Georg Brandlba83f822010-03-14 09:50:54 +00003500- Issue #7117: Backport round implementation from Python 3.x. ``round()`` now
3501 uses the correctly-rounded string <-> float conversions described above (when
3502 available), and so produces correctly rounded results that will display nicely
3503 under the float repr. There are two related small changes: (1) round now
3504 accepts any class with an ``__index__()`` method for its second argument (but
3505 no longer accepts floats for the second argument), and (2) an excessively
3506 large second integer argument (e.g., ``round(1.234, 10**100)``) no longer
3507 raises an exception.

3886 this code path is really executed because I cannot move to such directory on
3887 win2k)

3913 PyUnicode_DecodeUTF8() once, remember the result and output it in a second

5289
Amaury Forgeot d'Arc05e34492008-09-10 22:04:45 +00005290- Issue #3743: In a few places, PY_FORMAT_SIZE_T was incorrectly used with
5291 PyString_FromFormat or PyErr_Format to display size_t values. The macro
5292 PY_FORMAT_SIZE_T is designed to select the correct format for the OS
5293 ``printf`` function, whereas PyString_FromFormat has an independent
5294 implementation and uses "%zd" on all platforms for size_t values.
5295 This makes a difference on win64, where ``printf`` needs "%Id" to display
5296 64bit values.

Benjamin Peterson97179b02008-09-09 20:55:01 +00005298- Issue #3634: _weakref.ref(Exception).__init__() gave invalid return value on

5302 object; previously an int would be returned for small values. the __long__

Antoine Pitroud4ae97b2008-08-29 18:39:48 +00005313 was correctly parsed but parsing of subsequent arguments failed.
5314
Vinay Sajip35e3b032008-09-01 14:33:59 +00005315- Issue #2534: speed up isinstance() and issubclass() by 50-70%, so as to
Antoine Pitrou0668c622008-08-26 22:42:08 +00005316 match Python 2.5 speed despite the __instancecheck__ / __subclasscheck__
5317 mechanism. In the process, fix a bug where isinstance() and issubclass(),
5318 when given a tuple of classes as second argument, were looking up
5319 __instancecheck__ / __subclasscheck__ on the tuple rather than on each
5320 type object.
5321
Neal Norwitz18aa3882008-08-24 05:04:52 +00005322- Fix crashes on memory allocation failure found with failmalloc.

Brett Cannon1eaf0742008-09-02 01:25:16 +00005391 warnings.catch_warnings() along with some API cleanup. Expanding the tests
5392 for catch_warnings() also led to an improvement in the raising of a
5393 DeprecationWarning related to warnings.warn_explicit().
5394
Benjamin Peterson973e6c22008-09-01 23:12:58 +00005395- The deprecation warnings for the old camelCase threading API were removed.

Gregory P. Smithd7122032008-09-02 05:36:11 +00005406- Issue #3708: os.urandom no longer goes into an infinite loop when passed a
5407 non-integer floating point number.
5408
Vinay Sajip65d66e12008-09-04 07:31:21 +00005409- Issue #3110: multiprocessing fails to compiel on solaris 10 due to missing

5416 _check_logger_class from multiprocessing.
5417
Amaury Forgeot d'Arc293924b2008-09-02 23:19:56 +00005418- Issue #2975: When compiling several extension modules with Visual Studio 2008
5419 from the same python interpreter, some environment variables would grow
5420 without limit.
5421
Benjamin Peterson37346b22008-08-23 20:27:43 +00005422- Issue #3643: Added a few more checks to _testcapi to prevent segfaults by
5423 exploitation of poor argument checking.
5424
Gerhard Häringef2276b2008-09-12 13:54:06 +00005425- sqlite3: Changed docstring of iterdump() to mark method as "Non-standard".
5426
Gerhard Häring6e1afcf2008-09-12 18:58:57 +00005427- Issue #3103: Reduced globals symbols used by sqlite3 module and made sure all
5428 remaining ones have "pysqlite_" prefix.
5429
Gerhard Häringe6872eb2008-09-12 22:33:22 +00005430- Issue #3846: Release the GIL during sqlite3_prepare calls. This improves

5438 wrapper for warnings.catch_warnings() that makes it easier to check
5439 that expected warning messages are being reported.
5440

Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00005459What's New in Python 2.6 beta 3?
5460================================
5461
Barry Warsaw07a4a382008-08-21 01:15:08 +00005462*Release date: 20-Aug-2008*
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00005463
5464Core and Builtins
5465-----------------
5466
Guido van Rossumf8402962008-08-20 15:01:50 +00005467- Issue #1878: Remove Py_TPFLAGS_HAVE_VERSION_TAG from
5468 Py_TPFLAGS_DEFAULT when not building the core. This means 3rd party
5469 extensions do not automatically benefit from the class attribute
5470 cache; they will have to explicitly add Py_TPFLAGS_HAVE_VERSION_TAG
5471 to their tp_flags field if they care. This is a backwards
5472 compatibility feature; in 3.0, all types will use the cache by
5473 default.
5474
Benjamin Petersonf647dc12008-08-20 01:27:30 +00005475- Keyword arguments can now follow starred arguments. (``f(a, *args,
5476 keyword=23)`` is now valid syntax.)
5477
Thomas Heller0ad5ae02008-08-19 19:25:04 +00005478- ctypes function pointers that are COM methods have a boolean True
5479 value again.
5480
Martin v. Löwisf91d46a2008-08-12 14:49:50 +00005481- Issue #3139: Make buffer-interface thread-safe wrt. PyArg_ParseTuple,
5482 by denying s# to parse objects that have a releasebuffer procedure,
5483 and introducing s*.
5484
Georg Brandl1e13ea92008-08-11 09:07:59 +00005485- Issue #3537: Fix an assertion failure when an empty but presized dict
5486 object was stored in the freelist.
5487
Mark Dickinsonb6467572008-08-04 21:30:09 +00005488- Issue #1481296: Make long(float('nan')) and int(float('nan')) raise
5489 ValueError consistently across platforms.
5490
Amaury Forgeot d'Arc39fd6722008-07-31 21:28:03 +00005491- Issue #3479: On platforms where sizeof(int) is smaller than sizeof(long)
5492 (64bit Unix, for example), unichr() would truncate its argument and return
5493 u'\x00' for unichr(2**32). Now it properly raises an OverflowError.
5494
Neal Norwitze7d8be82008-07-31 17:17:14 +00005495- Apply security patches from Apple.
5496
Amaury Forgeot d'Arc246daed2008-07-31 00:42:16 +00005497- Issue #2542: Now that issubclass() may call arbitrary code, ensure that
5498 PyErr_ExceptionMatches returns 0 when an exception occurs there.
5499
Antoine Pitrou92f82162008-07-25 22:22:08 +00005500- Issue #1819: function calls with several named parameters are now on
5501 average 35% faster (as measured by pybench).
5502
Amaury Forgeot d'Arce4921fe2008-07-21 22:00:38 +00005503- Issue #2378: An unexpected UnboundLocalError or NameError could appear when
5504 the python debugger steps into a class statement: the free variables (local
5505 variables defined in an outer scope) would be deleted from the outer scope.
5506
Gregory P. Smith0470bab2008-07-22 04:46:32 +00005507- Issue #2620: Overflow checking when allocating or reallocating memory
5508 was not always being done properly in some python types and extension
5509 modules. PyMem_MALLOC, PyMem_REALLOC, PyMem_NEW and PyMem_RESIZE have
5510 all been updated to perform better checks and places in the code that
5511 would previously leak memory on the error path when such an allocation
5512 failed have been fixed.
5513
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00005514Library
5515-------
5516
Hirokazu Yamamoto838c79f2008-08-20 13:14:07 +00005517- Issue #3612: Added some missing basic types in ctypes.wintypes.
5518
Benjamin Petersone977ad42008-08-20 01:42:01 +00005519- The methods ``is_in_tuple()``, ``is_vararg()``, and ``is_keywordarg()`` of
5520 symtable.Symbol have been deprecated for removal in 3.0 and the next release.
5521
Amaury Forgeot d'Arc351ffb82008-08-18 19:23:47 +00005522- Issue #2234: distutils failed for some versions of the cygwin compiler. The
5523 version reported by these tools does not necessarily follow the python
5524 version numbering scheme, so the module is less strict when parsing it.
5525
Nick Coghlanf70385a2008-08-18 12:42:46 +00005526- Issue #2235: Added Py3k warnings for types which will become unhashable
5527 under the stricter __hash__ inheritance rules in 3.0. Several types
5528 which did not meet the rules for hash invariants and were already
5529 unhashable in 3.0 have now been explicitly flagged as unhashable in
5530 2.6 as well (collections.Mapping, collections.Set, unittest.TestSuite,
5531 xml.dom.minidom.NamedNodeMap, numbers.Number, UserList.UserList)
5532
Brett Cannon88f801d2008-08-18 00:46:22 +00005533- Update __all__ for cookielib, csv, os, urllib2, and weakref to include things
5534 imported into the module but exposed as part of the module's API.
5535
Brett Cannon7b96f072008-08-18 00:41:11 +00005536- Remove an unneeded import of abc.ABCMeta from 'inspect'.
5537
Brett Cannon46225e72008-08-18 00:36:52 +00005538- Remove unneeded imports of 'sys' and 'warnings' from 'io'.

Brett Cannon25c9d6a2008-08-17 22:10:11 +00005540- Remove unneeded imports of 'warnings' from shelve, filecmp, and dummy_thread.
5541
Hirokazu Yamamoto41a81eb2008-08-17 13:10:46 +00005542- Issue #3575: Incremental decoder's decode function now takes bytearray
5543 by using 's*' instead of 't#'.
5544
Mark Dickinson3e4caeb2009-02-21 20:27:01 +00005545- Issue #2222: Fixed reference leak when occurred os.rename()
Hirokazu Yamamoto7f30a682008-08-17 09:46:56 +00005546 fails unicode conversion on 2nd parameter. (windows only)
5547
Georg Brandl222e2082010-08-01 22:27:39 +00005548- Issue #2464: urllib2 now supports a malformation in the URL received
Facundo Batista94f243a2008-08-17 03:38:39 +00005549 in a redirect.
5550
Brett Cannonabe423e2008-08-16 21:47:07 +00005551- Silence the DeprecationWarning raised when importing mimetools in
Brett Cannon721b1452008-08-16 22:00:27 +00005552 BaseHTTPServer, cgi (and rfc822), httplib.
Brett Cannonabe423e2008-08-16 21:47:07 +00005553
Facundo Batistaeb90b782008-08-16 14:44:07 +00005554- Issue #2776: fixed small issue when handling an URL with double slash
5555 after a 302 response in the case of not going through a proxy.
5556
Antoine Pitroub90a8be2008-08-15 21:03:21 +00005557- Issue #2676: in the email package, content-type parsing was hanging on
5558 pathological input because of quadratic or exponential behaviour of a
5559 regular expression.
5560
Antoine Pitrou11ec65d2008-08-14 21:04:30 +00005561- Issue #3476: binary buffered reading through the new "io" library is now
5562 thread-safe.
5563
Brett Cannonbf3157b2008-08-14 05:00:03 +00005564- Silence the DeprecationWarning of rfc822 when it is imported by mimetools
5565 since mimetools itself is deprecated. Because modules are cached, all
5566 subsequent imports of rfc822 will not raise a visible DeprecationWarning.
5567
Antoine Pitrou9fcd4b32008-08-11 17:21:36 +00005568- Issue #3134: shutil referenced undefined WindowsError symbol.
5569
Robert Schuppenies14646332008-08-10 11:01:53 +00005570- Issue #1342811: Fix leak in Tkinter.Menu.delete. Commands associated to
5571 menu entries were not deleted.
5572
Brett Cannon83e81842008-08-09 23:30:55 +00005573- Copied the implementation of reduce() to _functools.reduce() to have a
5574 version that did not raise a DeprecationWarning under -3.
5575
Antoine Pitrou76b8bee2008-08-09 17:27:23 +00005576- Issue #3205: When iterating over a BZ2File fails allocating memory, raise
5577 a MemoryError rather than silently stop the iteration.
5578
Guido van Rossum59ce9012008-08-09 14:55:34 +00005579- Issue #3487: sre "bytecode" validator. Passing invalid "re-bytecode"
5580 to _sre.compile() will now be rejected. This should not affect anybody
5581 since the re.compile() function never generates invalid re-bytecode.
5582
Skip Montanaroa032bf42008-08-08 22:52:51 +00005583- Issue #3436: Make csv.DictReader's fieldnames attribute a property so that
5584 upon first access it can be automatically initialized from the csv file if
5585 it wasn't initialized during instantiation.
5586
Brett Cannon3aa2a492008-08-06 22:28:09 +00005587- Issue #2338: Create imp.reload() to help with transitioning to Python 3.0 as
5588 the reload() built-in has been removed.
5589
Brett Cannon7e30b672008-08-04 21:52:25 +00005590- Changed code in the following modules/packages to remove warnings raised
Brett Cannonc1b76e42008-08-09 23:06:16 +00005591 while running under the ``-3`` flag: aifc, asynchat, asyncore, bdb, bsddb,

Antoine Pitroude781a42008-08-09 12:43:23 +00005602 asking for a specific length. This problem only affected files opened
5603 using the new "io" module, not the built-in open() function.
Benjamin Peterson01a24322008-07-28 23:35:27 +00005604

5629 file name rather than a ZipInfo instance, so files are extracted with
5630 mode 0600 rather than 000 under Unix.
5631
Gregory P. Smitha36f8fe2008-08-04 00:13:29 +00005632- Issue #1857: subprocess.Popen.poll gained an additional _deadstate keyword
5633 argument in python 2.5, this broke code that subclassed Popen to include its
5634 own poll method. Fixed my moving _deadstate to an _internal_poll method.

5649 regarding lack of coverage of new-style classes have also been
5650 removed, since the coverage is now fairly reasonable.

5660
Georg Brandl3e483f62008-07-16 22:57:41 +00005661- Issue #3156: Fix inconsistent behavior of the bytearray type: all
5662 its methods now allow for items objects that can be converted to
5663 an integer using operator.index().
5664
Mark Dickinson64b7e502008-07-16 09:40:03 +00005665- Issue #3360: Fix incorrect parsing of '020000000000.0', which
5666 produced a ValueError instead of giving the correct float.
5667
Eric Smitha5fa5a22008-07-16 00:11:49 +00005668- Issue #3083: Add alternate (#) formatting for bin, oct, hex output
5669 for str.format(). This adds the prefix 0b, 0o, or 0x, respectively.
5670
Mark Dickinson7103aa42008-07-15 19:08:33 +00005671- Issue #3008: the float type has a new instance method 'float.hex'

Nick Coghlan6d6bd442008-07-15 15:40:22 +00005675- Issue #2235: __hash__ is once again inherited by default. To allow
5676 collections.Hashable to remain meaningful in the presence of the
5677 default hash implementation (object.__hash__), it is now possible
5678 to explicit block inheritance of hash by setting __hash__=None at
5679 the Python level, or tp_hash=PyObject_HashNotImplemented at the C
5680 level.
5681
Nick Coghlanb028f502008-07-13 14:52:36 +00005682- Issue #3221: Issue a RuntimeWarning instead of raising SystemError if
5683 the parent module cannot be found while performing an absolute import.
5684 This means that an incorrectly defined __package__ attribute will
5685 now only prevent relative imports in that module rather than causing
5686 all imports from that module to fail.

5699
Mark Dickinson1ec2fcd2008-06-20 14:53:43 +00005700- Issue #3004: Minor change to slice.indices(): the start and stop
5701 arguments are now treated identically, making the behaviour easier
5702 to describe and understand. For example, slice(None, -10,
5703 1).indices(9) now returns (0, 0, 1) instead of (0, -1, 1), and
5704 slice(None, 10, -1).indices(10) returns (9, 9, -1) instead of (9,
5705 10, -1).

5748 both unnecessary (HTTP allows text content to be sent in several forms) and
Andrew M. Kuchlingcc3f2b12008-07-10 14:43:31 +00005749 wrong because the actual transmitted size could differ from the

Georg Brandl5cc774e2008-06-11 20:28:06 +00006159 PPC64 and x86_64 support in one binary).
Ronald Oussoren5640ce22008-06-05 12:58:24 +00006160
6161 This is controlled by the configure argument ``--with-universal-archs``:

6164
6165 - ``--with-universal-archs=32-bit``: install 2-way universal, 32-bit (the default)
6166
6167 - ``--with-universal-archs=64-bit``: install 2-way universal, 64-bit
6168

6208 two handlers that derive the same default base class.

Christian Heimese74c8f22008-04-19 02:23:57 +00006210- Added kill, terminate and send_signal(sig) to subprocess.Popen.

Georg Brandl3ee81df2008-05-17 18:14:43 +00006221- Issue #1631171: Re-implement the 'warnings' module in C (the
6222 original Python code has been kept as backup). This will allow for
6223 using the 'warning's machinery in such places as the parser where
6224 use of pure Python code is not possible. Both the ``showarning()``
6225 and ``formatwarning()`` gain an optional 'line' argument which is
6226 not called by default for backwards-compatibility reasons. Setting
6227 ``warnings.showwarning()`` to an implementation that lacks support

Georg Brandl3ee81df2008-05-17 18:14:43 +00006291- Issue #2550: The approach used by client/server code for obtaining
6292 ports to listen on in network-oriented tests has been refined in an
6293 effort to facilitate running multiple instances of the entire
6294 regression test suite in parallel without issue.
6295 test_support.bind_port() has been fixed such that it will always
6296 return a unique port -- which wasn't always the case with the
6297 previous implementation, especially if socket options had been set
6298 that affected address reuse (i.e. SO_REUSEADDR, SO_REUSEPORT). The
6299 new implementation of bind_port() will actually raise an exception
6300 if it is passed an AF_INET/SOCK_STREAM socket with either the
6301 SO_REUSEADDR or SO_REUSEPORT socket option set. Furthermore, if
6302 available, bind_port() will set the SO_EXCLUSIVEADDRUSE option on
6303 the socket it's been passed. This currently only applies to
6304 Windows. This option prevents any other sockets from binding to the
6305 host/port we've bound to, thus removing the possibility of the
6306 'non-deterministic' behaviour, as Microsoft puts it, that occurs
6307 when a second SOCK_STREAM socket binds and accepts to a host/port
6308 that's already been bound by another socket. The optional preferred
6309 port parameter to bind_port() has been removed. Under no
6310 circumstances should tests be hard coding ports!
6311
6312 test_support.find_unused_port() has also been introduced, which will
6313 pass a temporary socket object to bind_port() in order to obtain an
6314 unused port. The temporary socket object is then closed and
6315 deleted, and the port is returned. This method should only be used
6316 for obtaining an unused port in order to pass to an external program
6317 (i.e. the -accept [port] argument to openssl's s_server mode) or as
6318 a parameter to a server-oriented class that doesn't give you direct
6319 access to the underlying socket used.
6320
6321 Finally, test_support.HOST has been introduced, which should be used
6322 for the host argument of any relevant socket calls (i.e. bind and
6323 connect).
Trent Nelsone41b0062008-04-08 23:47:30 +00006324
6325 The following tests were updated to following the new conventions:
Georg Brandl3ee81df2008-05-17 18:14:43 +00006326 test_socket, test_smtplib, test_asyncore, test_ssl, test_httplib,
Trent Nelsone41b0062008-04-08 23:47:30 +00006327 test_poplib, test_ftplib, test_telnetlib, test_socketserver,
6328 test_asynchat and test_socket_ssl.
6329
Georg Brandl3ee81df2008-05-17 18:14:43 +00006330 It is now possible for multiple instances of the regression test
6331 suite to run in parallel without issue.

Georg Brandl3ee81df2008-05-17 18:14:43 +00006497- Issue #1202: zlib.crc32 and zlib.adler32 no longer return different
6498 values on 32-bit vs. 64-bit python interpreters. Both were correct,
6499 but they now both return a signed integer object for consistency.

Eric Smitha73fbe72008-02-23 03:09:44 +00006610- Added the future_builtins module, which contains hex() and oct().
6611 These are the PEP 3127 version of these functions, designed to be
6612 compatible with the hex() and oct() builtins from Python 3.0. They
6613 differ slightly in their output formats from the existing, unchanged
6614 Python 2.6 builtins. The expected usage of the future_builtins
6615 module is:
6616 from future_builtins import hex, oct
6617
Eric Smith7ef40bf2008-02-20 23:34:22 +00006618- Issue #1600: Modifed PyOS_ascii_formatd to use at most 2 digit
6619 exponents for exponents with absolute value < 100. Follows C99
6620 standard. This is a change on Windows, which would use 3 digits.
6621 Also, added 'n' to the formats that PyOS_ascii_formatd understands,
6622 so that any alterations it does to the resulting string will be
6623 available in stringlib/formatter.h (for float.__format__).
6624
Eric Smith5a3c1352008-02-19 13:21:56 +00006625- Implemented PEP 3101, Advanced String Formatting. This adds a new
6626 builtin format(); a format() method for str and unicode; a
6627 __format__() method to object, str, unicode, int, long, float, and
6628 datetime; the class string.Formatter; and the C API
6629 PyObject_Format().
6630
Georg Brandl3ee81df2008-05-17 18:14:43 +00006631- Fixed several potential crashes, all caused by specially crafted
6632 __del__ methods exploiting objects in temporarily inconsistent
6633 state.
Amaury Forgeot d'Arc632fad32008-02-16 20:55:24 +00006634
Vinay Sajipb7edfc42008-04-02 21:10:23 +00006635- Issue #2115: Important speedup in setting __slot__ attributes. Also
Georg Brandl3ee81df2008-05-17 18:14:43 +00006636 prevent a possible crash: an Abstract Base Class would try to access
6637 a slot on a registered virtual subclass.
Amaury Forgeot d'Arc60d6c7f2008-02-15 21:22:45 +00006638
Georg Brandl3ee81df2008-05-17 18:14:43 +00006639- Fixed repr() and str() of complex numbers with infinity or nan as

Georg Brandl3ee81df2008-05-17 18:14:43 +00006642- Clear all free lists during a gc.collect() of the highest generation
6643 in order to allow pymalloc to free more arenas. Python may give back
6644 memory to the OS earlier.
Christian Heimes3b718a72008-02-14 12:47:33 +00006645
Georg Brandl3ee81df2008-05-17 18:14:43 +00006646- Issue #2045: Fix an infinite recursion triggered when printing a
6647 subclass of collections.defaultdict, if its default_factory is set
6648 to a bound method.
Amaury Forgeot d'Arcb01aa432008-02-08 00:56:02 +00006649
Christian Heimesf75dbef2008-02-08 00:11:31 +00006650- Fixed a minor memory leak in dictobject.c. The content of the free
6651 list was not freed on interpreter shutdown.
6652
Georg Brandl21e99f42010-03-07 15:23:59 +00006653- Limit free list of method and built-in function objects to 256
Georg Brandl3ee81df2008-05-17 18:14:43 +00006654 entries each.
Christian Heimes6075a822008-02-06 12:44:34 +00006655
Georg Brandl3ee81df2008-05-17 18:14:43 +00006656- Patch #1953: Added ``sys._compact_freelists()`` and the C API
6657 functions ``PyInt_CompactFreeList`` and ``PyFloat_CompactFreeList``
Christian Heimes422051a2008-02-04 18:00:12 +00006658 to compact the internal free lists of pre-allocted ints and floats.
6659
Georg Brandl3ee81df2008-05-17 18:14:43 +00006660- Issue #1983: Fixed return type of fork(), fork1() and forkpty()
6661 calls. Python expected the return type int but the fork familie
6662 returns pi_t.
Christian Heimes951cc0f2008-01-31 23:08:23 +00006663
Georg Brandl3ee81df2008-05-17 18:14:43 +00006664- Issue #1678380: Fix a bug that identifies 0j and -0j when they

6674 the internal lookup cache for ref leak tests.
Christian Heimes908caac2008-01-27 23:34:59 +00006675
Georg Brandl3ee81df2008-05-17 18:14:43 +00006676- Patch #1473257: generator objects gain a gi_code attribute. This is
6677 the same object as the func_code attribute of the function that
6678 produced the generator.
Georg Brandl0cdf9a32008-01-26 14:14:20 +00006679
Georg Brandl3ee81df2008-05-17 18:14:43 +00006680- Issue #1920: "while 0" statements were completely removed by the
6681 compiler, even in the presence of an "else" clause, which is
6682 supposed to be run when the condition is false. Now the compiler
6683 correctly emits bytecode for the "else" suite.
Amaury Forgeot d'Arc31eaafe2008-01-24 22:59:25 +00006684
Guido van Rossumeead05f2008-01-24 18:21:02 +00006685- A few crashers fixed: weakref_in_del.py (issue #1377858);
6686 loosing_dict_ref.py (issue #1303614, test67.py);
6687 borrowed_ref_[34].py (not in tracker).
6688
Vinay Sajipd7cf32e2008-01-24 12:43:33 +00006689- Issue #1069410: The "can't load dll" message box on Windows is
Christian Heimesb2302ba2008-01-23 17:15:06 +00006690 suppressed while an extension is loaded by calling SetErrorMode in
6691 dynload_win.c. The error is still reported properly.
6692
Georg Brandl3ee81df2008-05-17 18:14:43 +00006693- Issue #1915: Python compiles with --enable-unicode=no again. However
Christian Heimes082c9b02008-01-23 14:20:50 +00006694 several extension methods and modules do not work without unicode
6695 support.
6696
Georg Brandl26543b12008-01-21 18:36:51 +00006697- Issue #1882: when compiling code from a string, encoding cookies in the
6698 second line of code were not always recognized correctly.
6699
Georg Brandl14404b62008-01-19 19:27:05 +00006700- Issue #1679: "0x" was taken as a valid integer literal.
6701
Georg Brandl6caad7d2008-01-26 14:19:22 +00006702- Issue #1865: ``bytes`` as an alias for ``str`` and b"" as an alias "" were
Christian Heimes288e89a2008-01-18 18:24:07 +00006703 added.
6704
Christian Heimesc94e2b52008-01-14 04:13:37 +00006705- sys.float_info / PyFloat_GetInfo: The floating point information
6706 object was converted from a dict to a specialized structseq object.
6707
Georg Brandl3ee81df2008-05-17 18:14:43 +00006708- Patch #1816: Added sys.flags structseq. It exposes the status of
6709 most command line arguments and PYTHON* environment variables.
Christian Heimesf31b69f2008-01-14 03:42:48 +00006710
Georg Brandl3ee81df2008-05-17 18:14:43 +00006711- Objects/structseq.c: Implemented new structseq representation. The
6712 patch makes structseqs (e.g. the return value of os.stat) more
6713 readable.
Christian Heimes9c201962008-01-14 03:33:52 +00006714
Georg Brandl3ee81df2008-05-17 18:14:43 +00006715- Patch #1700288: added a type attribute cache that caches method

6724 envvar and sys.dont_write_bytecode attribute. All these can be set
6725 to forbid Python to attempt to write compiled bytecode files.
Georg Brandl2da0fce2008-01-07 17:09:35 +00006726
Georg Brandl3ee81df2008-05-17 18:14:43 +00006727- Improve some exception messages when Windows fails to load an
6728 extension module. Now we get for example '%1 is not a valid Win32
6729 application' instead of 'error code 193'.

Georg Brandl3ee81df2008-05-17 18:14:43 +00006740- Compiler now generates simpler and faster code for dictionary
6741 literals. The oparg for BUILD_MAP now indicates an estimated
6742 dictionary size. There is a new opcode, STORE_MAP, for adding
6743 entries to the dictionary.

Georg Brandl3ee81df2008-05-17 18:14:43 +00006788 smaller than LONG_MAX. Formerly, it raised an OverflowError. Now,
6789 automatically shifts from ints to longs.
Raymond Hettinger8f669372007-10-03 21:18:11 +00006790
Georg Brandl3ee81df2008-05-17 18:14:43 +00006791- Issue #1686386: Tuple's tp_repr did not take into account the
6792 possibility of having a self-referential tuple, which is possible
6793 from C code. Nor did object's tp_str consider that a type's tp_str
6794 could do something that could lead to an inifinite recursion.
6795 Py_ReprEnter() and Py_EnterRecursiveCall(), respectively, fixed the
6796 issues.

6799 'print' statement to write to a file since the GIL was not released
6800 as needed. Now PyObject_Print() does the right thing along with
6801 various tp_print implementations of the built-in types and those in
6802 the collections module.

Georg Brandl3ee81df2008-05-17 18:14:43 +00006812 PyObject_Call() never calling back out to Python code to trigger
6813 recursion depth updates/checks. Required the creation of a static

6863
Guido van Rossum143b5642007-03-23 04:58:42 +00006864- Bug #1683368: The object.__init__() and object.__new__() methods are
6865 now stricter in rejecting excess arguments. The only time when
6866 either allows excess arguments is when it is not overridden and the
6867 other one is. For backwards compatibility, when both are
6868 overridden, it is a deprecation warning (for now; maybe a Py3k
Guido van Rossum234b1ff2007-03-23 19:39:01 +00006869 warning later). Also, type.__init__() insists on the same signature
6870 as supported by type.__new__().

Georg Brandl3ee81df2008-05-17 18:14:43 +00006872- Patch #1675423: PyComplex_AsCComplex() now tries to convert an
6873 object to complex using its __complex__() method before falling back
6874 to the __float__() method. Therefore, the functions in the cmath
6875 module now can operate on objects that define a __complex__()
6876 method.

Georg Brandl7b9c5552007-03-12 14:30:05 +00006894- Bug #1678647: write a newline after printing an exception in any
6895 case, even when converting the value to a string failed.
6896
Georg Brandl871f1bc2007-03-12 13:17:36 +00006897- The dir() function has been extended to call the __dir__() method on
Georg Brandl3ee81df2008-05-17 18:14:43 +00006898 its argument, if it exists. If not, it will work like before. This
6899 allows customizing the output of dir() in the presence of a
6900 __getattr__().

6910 raising a ValueError.
Collin Wintere38051d2007-03-09 20:33:07 +00006911
Georg Brandlaa2321b2007-03-07 00:40:28 +00006912- Patch #703779: unset __file__ in __main__ after running a file. This
Georg Brandl3ee81df2008-05-17 18:14:43 +00006913 makes the filenames the warning module prints much more sensible
6914 when a PYTHONSTARTUP file is used.

6929
Georg Brandl3ee81df2008-05-17 18:14:43 +00006930- When printing an unraisable error, don't print exceptions. before

7498
Georg Brandl92a6bae2007-03-13 17:43:32 +00007499- Patch #1603688: ConfigParser.SafeConfigParser now checks values that
Georg Brandl3ee81df2008-05-17 18:14:43 +00007500 are set for invalid interpolation sequences that would lead to
7501 errors on reading back those values.

7557 TestCase and TestSuite subclasses (not instances) are no longer
7558 accepted in TestSuite.addTest(). This should cause no
7559 incompatibility since it never made sense with ordinary subclasses
7560 -- the failure just occurred later, with a more cumbersome
7561 exception.

Gregory P. Smithbde4ae42008-01-17 08:35:49 +00007848 that the SMTP.starttls() caller no longer needs to call ehlo()

Georg Brandl3ee81df2008-05-17 18:14:43 +00007850 does not claim to support starttls. Adds the

Georg Brandl3ee81df2008-05-17 18:14:43 +00007950 time so that opening a database previously created with the DB_DUP
7951 or DB_DUPSORT flag set will keep the proper behavior on subsequent
7952 opens. Specifically: dictionary assignment to a DB object will

Raymond Hettingerdc1d1ba2007-11-07 02:45:46 +00008234- Add a FAST_LOOPS build option that speeds-up looping by trading away
Georg Brandl3ee81df2008-05-17 18:14:43 +00008235 periodic threadstate and signal checking in tight loops. By
8236 default, this option is turned-off. It should only be enabled in
8237 debugged, performance critical applications.

Georg Brandl3ee81df2008-05-17 18:14:43 +00008295- ``PySet_Add()`` can now modify a newly created frozenset. Similarly
8296 to ``PyTuple_SetItem``, it can be used to populate a brand new

8309
Georg Brandl3ee81df2008-05-17 18:14:43 +00008310- Issue #1521: On 64bit platforms, using PyArgs_ParseTuple with the t#
8311 of w# format code incorrectly truncated the length to an int, even
8312 when PY_SSIZE_T_CLEAN is set. The str.decode method used to return
8313 incorrect results with huge strings.

Georg Brandl3ee81df2008-05-17 18:14:43 +00008343- Added case insensitive comparison methods ``PyOS_stricmp(char*,
8344 char*)`` and ``PyOS_strnicmp(char*, char*, Py_ssize_t)``.
Christian Heimes000a0742008-01-03 22:16:32 +00008345
