Ned Deily0d0ea482012-02-10 12:59:06 +0100549- Issue #13590: On OS X 10.7 and 10.6 with Xcode 4.2, building
550 Distutils-based packages with C extension modules may fail because
551 Apple has removed gcc-4.2, the version used to build python.org
552 64-bit/32-bit Pythons. If the user does not explicitly override
553 the default C compiler by setting the CC environment variable,
554 Distutils will now attempt to compile extension modules with clang
555 if gcc-4.2 is required but not found. Also as a convenience, if
556 the user does explicitly set CC, substitute its value as the default
557 compiler in the Distutils LDSHARED configuration variable for OS X.
558 (Note, the python.org 32-bit-only Pythons use gcc-4.0 and the 10.4u
559 SDK, neither of which are available in Xcode 4. This change does not
560 attempt to override settings to support their use with Xcode 4.)

Ned Deily87e82bb2011-06-28 19:52:59 -0700833- Issue #9516: On Mac OS X, change Distutils to no longer globally attempt to
834 check or set the MACOSX_DEPLOYMENT_TARGET environment variable for the
835 interpreter process. This could cause failures in non-Distutils subprocesses
836 and was unreliable since tests or user programs could modify the interpreter
837 environment after Distutils set it. Instead, have Distutils set the the
838 deployment target only in the environment of each build subprocess. It is
839 still possible to globally override the default by setting
840 MACOSX_DEPLOYMENT_TARGET before launching the interpreter; its value must be
841 greater or equal to the default value, the value with which the interpreter
842 was built.

872 the ticker doesn't have to wind down to zero from the old starting point
873 before the new interval takes effect. And if the user increases the
874 interval, it makes sure the new limit takes effect right away rather have an

1827 This prevents user-created self-referencing ordered dictionaries from
1828 becoming permanently uncollectable GC garbage. The downside is that
1829 removing __del__ means that the internal doubly-linked list has to wait for
1830 GC collection rather than freeing memory immediately when the refcnt drops
1831 to zero.

2675
Philip Jenveyaebbaeb2010-04-06 23:24:45 +00002676- Issue #7301: Add environment variable $PYTHONWARNINGS.
2677
Benjamin Peterson3a1dfa22010-04-06 21:50:00 +00002678- Issue #8329: Don't return the same lists from select.select when no fds are
2679 changed.
2680
Georg Brandlfee0f442010-05-22 21:26:21 +00002681- Issue #8259: ``1L << (2**31)`` no longer produces an 'outrageous shift error'
Mark Dickinson82791672010-04-06 16:47:55 +00002682 on 64-bit machines. The shift count for either left or right shift is
2683 permitted to be up to sys.maxsize.
2684
Benjamin Peterson4ceeeb02010-04-03 22:48:51 +00002685- Ensure that tokenization of identifiers is not affected by locale.

2690
Georg Brandlfee0f442010-05-22 21:26:21 +00002691- Issue #7994: Issue a PendingDeprecationWarning if object.__format__ is called
2692 with a non-empty format string. This is an effort to future-proof user
2693 code. If a derived class does not currently implement __format__ but later
2694 adds its own __format__, it would most likely break user code that had
Antoine Pitrou01a196a2011-01-02 20:05:11 +00002695 supplied a format string. This will be changed to a DeprecationWarning in
Georg Brandlfee0f442010-05-22 21:26:21 +00002696 Python 3.3 and it will be an error in Python 3.4.

Georg Brandlfee0f442010-05-22 21:26:21 +00002729- Issue #8257: The Decimal construct now accepts a float instance directly,
2730 converting that float to a Decimal of equal value:
Mark Dickinson8a950712010-04-03 15:47:46 +00002731

2733 Decimal('1.100000000000000088817841970012523233890533447265625')
2734
Raymond Hettinger34c35b22010-04-03 10:22:00 +00002735- collections.Counter() now supports a subtract() method.
2736
Georg Brandlfee0f442010-05-22 21:26:21 +00002737- The functools module now has a total_ordering() class decorator to simplify

Georg Brandlfee0f442010-05-22 21:26:21 +00002746- Issue #7279: Comparisons involving a Decimal signaling NaN now signal
2747 InvalidOperation instead of returning False. (Comparisons involving a quiet
2748 NaN are unchanged.) Also, Decimal quiet NaNs are now hashable; Decimal
2749 signaling NaNs remain unhashable.
Mark Dickinsone096e822010-04-02 10:17:07 +00002750
Georg Brandlfee0f442010-05-22 21:26:21 +00002751- Issue #2531: Comparison operations between floats and Decimal instances now
2752 return a result based on the numeric values of the operands; previously they
2753 returned an arbitrary result based on the relative ordering of id(float) and
2754 id(Decimal).
Mark Dickinson99d80962010-04-02 08:53:22 +00002755
Barry Warsawf7f2d6f2010-03-31 21:07:16 +00002756- Issue #8233: When run as a script, py_compile.py optionally takes a single
Georg Brandlfee0f442010-05-22 21:26:21 +00002757 argument `-` which tells it to read files to compile from stdin. Each line is
2758 read on demand and the named file is compiled immediately. (Original patch by
2759 Piotr Ożarowski).

Georg Brandlfee0f442010-05-22 21:26:21 +00002768- Comparisons using one of <, <=, >, >= between a complex instance and a
2769 Fractions instance now raise TypeError instead of returning True/False. This
2770 makes Fraction <=> complex comparisons consistent with int <=> complex, float
2771 <=> complex, and complex <=> complex comparisons.

2880 the set of integer codes for which it was used differed between native packing
2881 and standard packing.)

3134 could crash in many places because of the ``PyByteArray_AS_STRING()`` macro
3135 returning NULL. The macro now returns a statically allocated empty string
3136 instead.

Georg Brandlba83f822010-03-14 09:50:54 +00003189 file position when calling `truncate()`. It would previously change the file
3190 position to the given argument, which goes against the tradition of
Antoine Pitrouf3fa0742010-01-31 22:26:04 +00003191 ftruncate() and other truncation APIs. Patch by Pascal Chambon.

3194 class used to represent files stored inside an archive. The new
3195 implementation is significantly faster and can be wrapped in a

3197 where interleaved calls to ``read()`` and ``readline()`` give wrong results.

Georg Brandlba83f822010-03-14 09:50:54 +00003208- Issue #7748: Since unicode values are supported for some metadata options in
3209 Distutils, the DistributionMetadata get_* methods will now return an utf-8
3210 encoded string for them. This ensures that the upload and register commands
3211 send the correct values to PyPI without any error.

Mark Dickinson1b34d252010-01-01 17:27:30 +00003294- Issue #5080: A number of functions and methods previously produced a
Georg Brandlba83f822010-03-14 09:50:54 +00003295 DeprecationWarning when passed a float argument where an integer was expected.
3296 These functions and methods now raise TypeError instead. The majority of the
3297 effects of this change are in the extension modules, but some core functions
3298 and methods are affected: notably the 'chr', 'range' and 'xrange' builtins,
3299 and many unicode/str methods.

Georg Brandlba83f822010-03-14 09:50:54 +00003482- Issue #7117: ``repr(x)`` for a float x returns a result based on the shortest
3483 decimal string that's guaranteed to round back to x under correct rounding
3484 (with round-half-to-even rounding mode). Previously it gave a string based on
3485 rounding x to 17 decimal digits. repr(x) for a complex number behaves
3486 similarly. On platforms where the correctly-rounded strtod and dtoa code is
3487 not supported (see below), repr is unchanged.
Mark Dickinsonb678de82009-11-19 18:41:49 +00003488
Georg Brandlba83f822010-03-14 09:50:54 +00003489- Issue #7117: On almost all platforms: float-to-string and string-to-float
3490 conversions within Python are now correctly rounded. Places these conversions
3491 occur include: str for floats and complex numbers; the float and complex
3492 constructors; old-style and new-style numeric formatting; serialization and
3493 deserialization of floats and complex numbers using marshal, pickle and json;
3494 parsing of float and imaginary literals in Python code; Decimal-to-float
3495 conversion.
Mark Dickinsonb678de82009-11-19 18:41:49 +00003496
Georg Brandlba83f822010-03-14 09:50:54 +00003497 The conversions use a Python-adapted version of David Gay's well-known dtoa.c,
3498 providing correctly-rounded strtod and dtoa C functions. This code is
3499 supported on Windows, and on Unix-like platforms using gcc, icc or suncc as
3500 the C compiler. There may be a small number of platforms on which correct
3501 operation of this code cannot be guaranteed, so the code is not used: notably,
3502 this applies to platforms where the C double format is not IEEE 754 binary64,
3503 and to platforms on x86 hardware where the x87 FPU is set to 64-bit precision
3504 and Python's configure script is unable to determine how to change the FPU
3505 precision. On these platforms conversions use the platform strtod and dtoa,
3506 as before.

Georg Brandlba83f822010-03-14 09:50:54 +00003508- Issue #7117: Backport round implementation from Python 3.x. ``round()`` now
3509 uses the correctly-rounded string <-> float conversions described above (when
3510 available), and so produces correctly rounded results that will display nicely
3511 under the float repr. There are two related small changes: (1) round now
3512 accepts any class with an ``__index__()`` method for its second argument (but
3513 no longer accepts floats for the second argument), and (2) an excessively
3514 large second integer argument (e.g., ``round(1.234, 10**100)``) no longer
3515 raises an exception.

3894 this code path is really executed because I cannot move to such directory on

3921 PyUnicode_DecodeUTF8() once, remember the result and output it in a second

Amaury Forgeot d'Arc05e34492008-09-10 22:04:45 +00005298- Issue #3743: In a few places, PY_FORMAT_SIZE_T was incorrectly used with
5299 PyString_FromFormat or PyErr_Format to display size_t values. The macro
5300 PY_FORMAT_SIZE_T is designed to select the correct format for the OS
5301 ``printf`` function, whereas PyString_FromFormat has an independent
5302 implementation and uses "%zd" on all platforms for size_t values.
5303 This makes a difference on win64, where ``printf`` needs "%Id" to display
5304 64bit values.

Antoine Pitrou0668c622008-08-26 22:42:08 +00005324 match Python 2.5 speed despite the __instancecheck__ / __subclasscheck__
5325 mechanism. In the process, fix a bug where isinstance() and issubclass(),
5326 when given a tuple of classes as second argument, were looking up
5327 __instancecheck__ / __subclasscheck__ on the tuple rather than on each
5328 type object.

Brett Cannon1eaf0742008-09-02 01:25:16 +00005399 warnings.catch_warnings() along with some API cleanup. Expanding the tests
5400 for catch_warnings() also led to an improvement in the raising of a
5401 DeprecationWarning related to warnings.warn_explicit().
5402
Benjamin Peterson973e6c22008-09-01 23:12:58 +00005403- The deprecation warnings for the old camelCase threading API were removed.

5424 _check_logger_class from multiprocessing.
5425
Amaury Forgeot d'Arc293924b2008-09-02 23:19:56 +00005426- Issue #2975: When compiling several extension modules with Visual Studio 2008
5427 from the same python interpreter, some environment variables would grow
5428 without limit.
5429
Benjamin Peterson37346b22008-08-23 20:27:43 +00005430- Issue #3643: Added a few more checks to _testcapi to prevent segfaults by
5431 exploitation of poor argument checking.
5432
Gerhard Häringef2276b2008-09-12 13:54:06 +00005433- sqlite3: Changed docstring of iterdump() to mark method as "Non-standard".
5434
Gerhard Häring6e1afcf2008-09-12 18:58:57 +00005435- Issue #3103: Reduced globals symbols used by sqlite3 module and made sure all
5436 remaining ones have "pysqlite_" prefix.
5437
Gerhard Häringe6872eb2008-09-12 22:33:22 +00005438- Issue #3846: Release the GIL during sqlite3_prepare calls. This improves

5446 wrapper for warnings.catch_warnings() that makes it easier to check
5447 that expected warning messages are being reported.
5448
Amaury Forgeot d'Arcfeb8cad2008-09-06 20:53:51 +00005449- Issue #3796: Some tests functions were not enabled in test_float.

Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00005467What's New in Python 2.6 beta 3?
5468================================
5469
Barry Warsaw07a4a382008-08-21 01:15:08 +00005470*Release date: 20-Aug-2008*
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00005471
5472Core and Builtins
5473-----------------
5474
Guido van Rossumf8402962008-08-20 15:01:50 +00005475- Issue #1878: Remove Py_TPFLAGS_HAVE_VERSION_TAG from
5476 Py_TPFLAGS_DEFAULT when not building the core. This means 3rd party
5477 extensions do not automatically benefit from the class attribute
5478 cache; they will have to explicitly add Py_TPFLAGS_HAVE_VERSION_TAG
5479 to their tp_flags field if they care. This is a backwards
5480 compatibility feature; in 3.0, all types will use the cache by
5481 default.
5482
Benjamin Petersonf647dc12008-08-20 01:27:30 +00005483- Keyword arguments can now follow starred arguments. (``f(a, *args,
5484 keyword=23)`` is now valid syntax.)
5485
Thomas Heller0ad5ae02008-08-19 19:25:04 +00005486- ctypes function pointers that are COM methods have a boolean True
5487 value again.
5488
Martin v. Löwisf91d46a2008-08-12 14:49:50 +00005489- Issue #3139: Make buffer-interface thread-safe wrt. PyArg_ParseTuple,
5490 by denying s# to parse objects that have a releasebuffer procedure,
5491 and introducing s*.
5492
Georg Brandl1e13ea92008-08-11 09:07:59 +00005493- Issue #3537: Fix an assertion failure when an empty but presized dict
5494 object was stored in the freelist.
5495
Mark Dickinsonb6467572008-08-04 21:30:09 +00005496- Issue #1481296: Make long(float('nan')) and int(float('nan')) raise
5497 ValueError consistently across platforms.
5498
Amaury Forgeot d'Arc39fd6722008-07-31 21:28:03 +00005499- Issue #3479: On platforms where sizeof(int) is smaller than sizeof(long)
5500 (64bit Unix, for example), unichr() would truncate its argument and return
5501 u'\x00' for unichr(2**32). Now it properly raises an OverflowError.
5502
Neal Norwitze7d8be82008-07-31 17:17:14 +00005503- Apply security patches from Apple.
5504
Amaury Forgeot d'Arc246daed2008-07-31 00:42:16 +00005505- Issue #2542: Now that issubclass() may call arbitrary code, ensure that
5506 PyErr_ExceptionMatches returns 0 when an exception occurs there.
5507
Antoine Pitrou92f82162008-07-25 22:22:08 +00005508- Issue #1819: function calls with several named parameters are now on
5509 average 35% faster (as measured by pybench).
5510
Amaury Forgeot d'Arce4921fe2008-07-21 22:00:38 +00005511- Issue #2378: An unexpected UnboundLocalError or NameError could appear when
5512 the python debugger steps into a class statement: the free variables (local
5513 variables defined in an outer scope) would be deleted from the outer scope.
5514
Gregory P. Smith0470bab2008-07-22 04:46:32 +00005515- Issue #2620: Overflow checking when allocating or reallocating memory
5516 was not always being done properly in some python types and extension
5517 modules. PyMem_MALLOC, PyMem_REALLOC, PyMem_NEW and PyMem_RESIZE have
5518 all been updated to perform better checks and places in the code that
5519 would previously leak memory on the error path when such an allocation
5520 failed have been fixed.
5521
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00005522Library
5523-------
5524
Hirokazu Yamamoto838c79f2008-08-20 13:14:07 +00005525- Issue #3612: Added some missing basic types in ctypes.wintypes.
5526
Benjamin Petersone977ad42008-08-20 01:42:01 +00005527- The methods ``is_in_tuple()``, ``is_vararg()``, and ``is_keywordarg()`` of
5528 symtable.Symbol have been deprecated for removal in 3.0 and the next release.
5529
Amaury Forgeot d'Arc351ffb82008-08-18 19:23:47 +00005530- Issue #2234: distutils failed for some versions of the cygwin compiler. The
5531 version reported by these tools does not necessarily follow the python
5532 version numbering scheme, so the module is less strict when parsing it.
5533
Nick Coghlanf70385a2008-08-18 12:42:46 +00005534- Issue #2235: Added Py3k warnings for types which will become unhashable
5535 under the stricter __hash__ inheritance rules in 3.0. Several types
5536 which did not meet the rules for hash invariants and were already
5537 unhashable in 3.0 have now been explicitly flagged as unhashable in
5538 2.6 as well (collections.Mapping, collections.Set, unittest.TestSuite,
5539 xml.dom.minidom.NamedNodeMap, numbers.Number, UserList.UserList)
5540
Brett Cannon88f801d2008-08-18 00:46:22 +00005541- Update __all__ for cookielib, csv, os, urllib2, and weakref to include things
5542 imported into the module but exposed as part of the module's API.
5543
Brett Cannon7b96f072008-08-18 00:41:11 +00005544- Remove an unneeded import of abc.ABCMeta from 'inspect'.
5545

Brett Cannon25c9d6a2008-08-17 22:10:11 +00005548- Remove unneeded imports of 'warnings' from shelve, filecmp, and dummy_thread.
5549
Hirokazu Yamamoto41a81eb2008-08-17 13:10:46 +00005550- Issue #3575: Incremental decoder's decode function now takes bytearray
5551 by using 's*' instead of 't#'.
5552
Mark Dickinson3e4caeb2009-02-21 20:27:01 +00005553- Issue #2222: Fixed reference leak when occurred os.rename()
Hirokazu Yamamoto7f30a682008-08-17 09:46:56 +00005554 fails unicode conversion on 2nd parameter. (windows only)
5555
Georg Brandl222e2082010-08-01 22:27:39 +00005556- Issue #2464: urllib2 now supports a malformation in the URL received
Facundo Batista94f243a2008-08-17 03:38:39 +00005557 in a redirect.
5558
Brett Cannonabe423e2008-08-16 21:47:07 +00005559- Silence the DeprecationWarning raised when importing mimetools in
Brett Cannon721b1452008-08-16 22:00:27 +00005560 BaseHTTPServer, cgi (and rfc822), httplib.
Brett Cannonabe423e2008-08-16 21:47:07 +00005561
Facundo Batistaeb90b782008-08-16 14:44:07 +00005562- Issue #2776: fixed small issue when handling an URL with double slash
5563 after a 302 response in the case of not going through a proxy.
5564
Antoine Pitroub90a8be2008-08-15 21:03:21 +00005565- Issue #2676: in the email package, content-type parsing was hanging on
5566 pathological input because of quadratic or exponential behaviour of a
5567 regular expression.
5568
Antoine Pitrou11ec65d2008-08-14 21:04:30 +00005569- Issue #3476: binary buffered reading through the new "io" library is now
5570 thread-safe.
5571
Brett Cannonbf3157b2008-08-14 05:00:03 +00005572- Silence the DeprecationWarning of rfc822 when it is imported by mimetools
5573 since mimetools itself is deprecated. Because modules are cached, all
5574 subsequent imports of rfc822 will not raise a visible DeprecationWarning.
5575
Antoine Pitrou9fcd4b32008-08-11 17:21:36 +00005576- Issue #3134: shutil referenced undefined WindowsError symbol.
5577
Robert Schuppenies14646332008-08-10 11:01:53 +00005578- Issue #1342811: Fix leak in Tkinter.Menu.delete. Commands associated to
5579 menu entries were not deleted.
5580
Brett Cannon83e81842008-08-09 23:30:55 +00005581- Copied the implementation of reduce() to _functools.reduce() to have a
5582 version that did not raise a DeprecationWarning under -3.
5583
Antoine Pitrou76b8bee2008-08-09 17:27:23 +00005584- Issue #3205: When iterating over a BZ2File fails allocating memory, raise
5585 a MemoryError rather than silently stop the iteration.
5586
Guido van Rossum59ce9012008-08-09 14:55:34 +00005587- Issue #3487: sre "bytecode" validator. Passing invalid "re-bytecode"
5588 to _sre.compile() will now be rejected. This should not affect anybody
5589 since the re.compile() function never generates invalid re-bytecode.
5590
Skip Montanaroa032bf42008-08-08 22:52:51 +00005591- Issue #3436: Make csv.DictReader's fieldnames attribute a property so that
5592 upon first access it can be automatically initialized from the csv file if
5593 it wasn't initialized during instantiation.
5594
Brett Cannon3aa2a492008-08-06 22:28:09 +00005595- Issue #2338: Create imp.reload() to help with transitioning to Python 3.0 as
5596 the reload() built-in has been removed.
5597
Brett Cannon7e30b672008-08-04 21:52:25 +00005598- Changed code in the following modules/packages to remove warnings raised
Brett Cannonc1b76e42008-08-09 23:06:16 +00005599 while running under the ``-3`` flag: aifc, asynchat, asyncore, bdb, bsddb,

Antoine Pitroude781a42008-08-09 12:43:23 +00005610 asking for a specific length. This problem only affected files opened
5611 using the new "io" module, not the built-in open() function.
Benjamin Peterson01a24322008-07-28 23:35:27 +00005612

5637 file name rather than a ZipInfo instance, so files are extracted with
5638 mode 0600 rather than 000 under Unix.
5639
Gregory P. Smitha36f8fe2008-08-04 00:13:29 +00005640- Issue #1857: subprocess.Popen.poll gained an additional _deadstate keyword
5641 argument in python 2.5, this broke code that subclassed Popen to include its
5642 own poll method. Fixed my moving _deadstate to an _internal_poll method.

5657 regarding lack of coverage of new-style classes have also been
5658 removed, since the coverage is now fairly reasonable.

5668
Georg Brandl3e483f62008-07-16 22:57:41 +00005669- Issue #3156: Fix inconsistent behavior of the bytearray type: all
5670 its methods now allow for items objects that can be converted to
5671 an integer using operator.index().
5672
Mark Dickinson64b7e502008-07-16 09:40:03 +00005673- Issue #3360: Fix incorrect parsing of '020000000000.0', which
5674 produced a ValueError instead of giving the correct float.
5675
Eric Smitha5fa5a22008-07-16 00:11:49 +00005676- Issue #3083: Add alternate (#) formatting for bin, oct, hex output

5678
Mark Dickinson7103aa42008-07-15 19:08:33 +00005679- Issue #3008: the float type has a new instance method 'float.hex'
5680 and a new class method 'float.fromhex' to convert floating-point
5681 numbers to and from hexadecimal strings, respectively.
5682
Nick Coghlan6d6bd442008-07-15 15:40:22 +00005683- Issue #2235: __hash__ is once again inherited by default. To allow
5684 collections.Hashable to remain meaningful in the presence of the
5685 default hash implementation (object.__hash__), it is now possible
5686 to explicit block inheritance of hash by setting __hash__=None at
5687 the Python level, or tp_hash=PyObject_HashNotImplemented at the C
5688 level.

Nick Coghlanb028f502008-07-13 14:52:36 +00005690- Issue #3221: Issue a RuntimeWarning instead of raising SystemError if
5691 the parent module cannot be found while performing an absolute import.
5692 This means that an incorrectly defined __package__ attribute will
5693 now only prevent relative imports in that module rather than causing
5694 all imports from that module to fail.
5695
Nick Coghlan14ff9942008-07-08 14:21:42 +00005696- Issue #2517: Allow unicode messages in Exceptions again by correctly

5707
Mark Dickinson1ec2fcd2008-06-20 14:53:43 +00005708- Issue #3004: Minor change to slice.indices(): the start and stop
5709 arguments are now treated identically, making the behaviour easier
5710 to describe and understand. For example, slice(None, -10,
5711 1).indices(9) now returns (0, 0, 1) instead of (0, -1, 1), and
5712 slice(None, 10, -1).indices(10) returns (9, 9, -1) instead of (9,
5713 10, -1).

5756 both unnecessary (HTTP allows text content to be sent in several forms) and
Andrew M. Kuchlingcc3f2b12008-07-10 14:43:31 +00005757 wrong because the actual transmitted size could differ from the

Georg Brandl3ee81df2008-05-17 18:14:43 +00006229- Issue #1631171: Re-implement the 'warnings' module in C (the
6230 original Python code has been kept as backup). This will allow for
6231 using the 'warning's machinery in such places as the parser where
6232 use of pure Python code is not possible. Both the ``showarning()``
6233 and ``formatwarning()`` gain an optional 'line' argument which is

Georg Brandl3ee81df2008-05-17 18:14:43 +00006299- Issue #2550: The approach used by client/server code for obtaining
6300 ports to listen on in network-oriented tests has been refined in an
6301 effort to facilitate running multiple instances of the entire
6302 regression test suite in parallel without issue.
6303 test_support.bind_port() has been fixed such that it will always
6304 return a unique port -- which wasn't always the case with the
6305 previous implementation, especially if socket options had been set
6306 that affected address reuse (i.e. SO_REUSEADDR, SO_REUSEPORT). The
6307 new implementation of bind_port() will actually raise an exception
6308 if it is passed an AF_INET/SOCK_STREAM socket with either the
6309 SO_REUSEADDR or SO_REUSEPORT socket option set. Furthermore, if
6310 available, bind_port() will set the SO_EXCLUSIVEADDRUSE option on
6311 the socket it's been passed. This currently only applies to
6312 Windows. This option prevents any other sockets from binding to the
6313 host/port we've bound to, thus removing the possibility of the
6314 'non-deterministic' behaviour, as Microsoft puts it, that occurs
6315 when a second SOCK_STREAM socket binds and accepts to a host/port
6316 that's already been bound by another socket. The optional preferred
6317 port parameter to bind_port() has been removed. Under no
6318 circumstances should tests be hard coding ports!
6319
6320 test_support.find_unused_port() has also been introduced, which will
6321 pass a temporary socket object to bind_port() in order to obtain an
6322 unused port. The temporary socket object is then closed and
6323 deleted, and the port is returned. This method should only be used
6324 for obtaining an unused port in order to pass to an external program
6325 (i.e. the -accept [port] argument to openssl's s_server mode) or as
6326 a parameter to a server-oriented class that doesn't give you direct
6327 access to the underlying socket used.
6328
6329 Finally, test_support.HOST has been introduced, which should be used
6330 for the host argument of any relevant socket calls (i.e. bind and
6331 connect).
Trent Nelsone41b0062008-04-08 23:47:30 +00006332
6333 The following tests were updated to following the new conventions:
Georg Brandl3ee81df2008-05-17 18:14:43 +00006334 test_socket, test_smtplib, test_asyncore, test_ssl, test_httplib,
Trent Nelsone41b0062008-04-08 23:47:30 +00006335 test_poplib, test_ftplib, test_telnetlib, test_socketserver,
6336 test_asynchat and test_socket_ssl.
6337
Georg Brandl3ee81df2008-05-17 18:14:43 +00006338 It is now possible for multiple instances of the regression test
6339 suite to run in parallel without issue.

Georg Brandl3ee81df2008-05-17 18:14:43 +00006505- Issue #1202: zlib.crc32 and zlib.adler32 no longer return different
6506 values on 32-bit vs. 64-bit python interpreters. Both were correct,
6507 but they now both return a signed integer object for consistency.

Eric Smitha73fbe72008-02-23 03:09:44 +00006618- Added the future_builtins module, which contains hex() and oct().
6619 These are the PEP 3127 version of these functions, designed to be
6620 compatible with the hex() and oct() builtins from Python 3.0. They
6621 differ slightly in their output formats from the existing, unchanged
6622 Python 2.6 builtins. The expected usage of the future_builtins
6623 module is:
6624 from future_builtins import hex, oct
6625
Eric Smith7ef40bf2008-02-20 23:34:22 +00006626- Issue #1600: Modifed PyOS_ascii_formatd to use at most 2 digit
6627 exponents for exponents with absolute value < 100. Follows C99
6628 standard. This is a change on Windows, which would use 3 digits.
6629 Also, added 'n' to the formats that PyOS_ascii_formatd understands,
6630 so that any alterations it does to the resulting string will be
6631 available in stringlib/formatter.h (for float.__format__).
6632
Eric Smith5a3c1352008-02-19 13:21:56 +00006633- Implemented PEP 3101, Advanced String Formatting. This adds a new
6634 builtin format(); a format() method for str and unicode; a
6635 __format__() method to object, str, unicode, int, long, float, and
6636 datetime; the class string.Formatter; and the C API
6637 PyObject_Format().
6638
Georg Brandl3ee81df2008-05-17 18:14:43 +00006639- Fixed several potential crashes, all caused by specially crafted
6640 __del__ methods exploiting objects in temporarily inconsistent
6641 state.
Amaury Forgeot d'Arc632fad32008-02-16 20:55:24 +00006642
Vinay Sajipb7edfc42008-04-02 21:10:23 +00006643- Issue #2115: Important speedup in setting __slot__ attributes. Also
Georg Brandl3ee81df2008-05-17 18:14:43 +00006644 prevent a possible crash: an Abstract Base Class would try to access
6645 a slot on a registered virtual subclass.
Amaury Forgeot d'Arc60d6c7f2008-02-15 21:22:45 +00006646

Georg Brandl3ee81df2008-05-17 18:14:43 +00006650- Clear all free lists during a gc.collect() of the highest generation
6651 in order to allow pymalloc to free more arenas. Python may give back
6652 memory to the OS earlier.
Christian Heimes3b718a72008-02-14 12:47:33 +00006653
Georg Brandl3ee81df2008-05-17 18:14:43 +00006654- Issue #2045: Fix an infinite recursion triggered when printing a
6655 subclass of collections.defaultdict, if its default_factory is set
6656 to a bound method.
Amaury Forgeot d'Arcb01aa432008-02-08 00:56:02 +00006657
Christian Heimesf75dbef2008-02-08 00:11:31 +00006658- Fixed a minor memory leak in dictobject.c. The content of the free
6659 list was not freed on interpreter shutdown.
6660
Georg Brandl21e99f42010-03-07 15:23:59 +00006661- Limit free list of method and built-in function objects to 256
Georg Brandl3ee81df2008-05-17 18:14:43 +00006662 entries each.
Christian Heimes6075a822008-02-06 12:44:34 +00006663
Georg Brandl3ee81df2008-05-17 18:14:43 +00006664- Patch #1953: Added ``sys._compact_freelists()`` and the C API
6665 functions ``PyInt_CompactFreeList`` and ``PyFloat_CompactFreeList``
Christian Heimes422051a2008-02-04 18:00:12 +00006666 to compact the internal free lists of pre-allocted ints and floats.
6667
Georg Brandl3ee81df2008-05-17 18:14:43 +00006668- Issue #1983: Fixed return type of fork(), fork1() and forkpty()
6669 calls. Python expected the return type int but the fork familie
6670 returns pi_t.
Christian Heimes951cc0f2008-01-31 23:08:23 +00006671
Georg Brandl3ee81df2008-05-17 18:14:43 +00006672- Issue #1678380: Fix a bug that identifies 0j and -0j when they

6682 the internal lookup cache for ref leak tests.
Christian Heimes908caac2008-01-27 23:34:59 +00006683
Georg Brandl3ee81df2008-05-17 18:14:43 +00006684- Patch #1473257: generator objects gain a gi_code attribute. This is
6685 the same object as the func_code attribute of the function that
6686 produced the generator.
Georg Brandl0cdf9a32008-01-26 14:14:20 +00006687
Georg Brandl3ee81df2008-05-17 18:14:43 +00006688- Issue #1920: "while 0" statements were completely removed by the
6689 compiler, even in the presence of an "else" clause, which is
6690 supposed to be run when the condition is false. Now the compiler
6691 correctly emits bytecode for the "else" suite.
Amaury Forgeot d'Arc31eaafe2008-01-24 22:59:25 +00006692
Guido van Rossumeead05f2008-01-24 18:21:02 +00006693- A few crashers fixed: weakref_in_del.py (issue #1377858);
6694 loosing_dict_ref.py (issue #1303614, test67.py);
6695 borrowed_ref_[34].py (not in tracker).
6696
Vinay Sajipd7cf32e2008-01-24 12:43:33 +00006697- Issue #1069410: The "can't load dll" message box on Windows is
Christian Heimesb2302ba2008-01-23 17:15:06 +00006698 suppressed while an extension is loaded by calling SetErrorMode in
6699 dynload_win.c. The error is still reported properly.
6700
Georg Brandl3ee81df2008-05-17 18:14:43 +00006701- Issue #1915: Python compiles with --enable-unicode=no again. However
Christian Heimes082c9b02008-01-23 14:20:50 +00006702 several extension methods and modules do not work without unicode
6703 support.
6704
Georg Brandl26543b12008-01-21 18:36:51 +00006705- Issue #1882: when compiling code from a string, encoding cookies in the
6706 second line of code were not always recognized correctly.
6707
Georg Brandl14404b62008-01-19 19:27:05 +00006708- Issue #1679: "0x" was taken as a valid integer literal.
6709
Georg Brandl6caad7d2008-01-26 14:19:22 +00006710- Issue #1865: ``bytes`` as an alias for ``str`` and b"" as an alias "" were
Christian Heimes288e89a2008-01-18 18:24:07 +00006711 added.
6712
Christian Heimesc94e2b52008-01-14 04:13:37 +00006713- sys.float_info / PyFloat_GetInfo: The floating point information
6714 object was converted from a dict to a specialized structseq object.
6715
Georg Brandl3ee81df2008-05-17 18:14:43 +00006716- Patch #1816: Added sys.flags structseq. It exposes the status of
6717 most command line arguments and PYTHON* environment variables.
Christian Heimesf31b69f2008-01-14 03:42:48 +00006718
Georg Brandl3ee81df2008-05-17 18:14:43 +00006719- Objects/structseq.c: Implemented new structseq representation. The
6720 patch makes structseqs (e.g. the return value of os.stat) more
6721 readable.
Christian Heimes9c201962008-01-14 03:33:52 +00006722
Georg Brandl3ee81df2008-05-17 18:14:43 +00006723- Patch #1700288: added a type attribute cache that caches method

6732 envvar and sys.dont_write_bytecode attribute. All these can be set
6733 to forbid Python to attempt to write compiled bytecode files.
Georg Brandl2da0fce2008-01-07 17:09:35 +00006734
Georg Brandl3ee81df2008-05-17 18:14:43 +00006735- Improve some exception messages when Windows fails to load an
6736 extension module. Now we get for example '%1 is not a valid Win32
6737 application' instead of 'error code 193'.

Georg Brandl3ee81df2008-05-17 18:14:43 +00006745 and INF. float("nan"), float("inf") and float("-inf") now work on
6746 every platform with IEEE 754 semantics.

Georg Brandl3ee81df2008-05-17 18:14:43 +00006748- Compiler now generates simpler and faster code for dictionary
6749 literals. The oparg for BUILD_MAP now indicates an estimated
6750 dictionary size. There is a new opcode, STORE_MAP, for adding
6751 entries to the dictionary.

6763
Nick Coghlanef01d822007-12-03 12:55:17 +00006764- PEP 366: Allow explicit relative imports when executing modules

Georg Brandl3ee81df2008-05-17 18:14:43 +00006780- Patch #1739468: Directories and zipfiles containing a __main__.py
6781 file can now be directly executed by passing their name to the
6782 interpreter. The directory/zipfile is automatically inserted as the
6783 first entry in sys.path.

Georg Brandl3ee81df2008-05-17 18:14:43 +00006785- Issue #1265: Fix a problem with sys.settrace, if the tracing
6786 function uses a generator expression when at the same time the
6787 executed code is closing a paused generator.
Amaury Forgeot d'Arc0d75f092007-11-13 21:54:28 +00006788
Raymond Hettinger1760c8a2007-11-08 02:52:43 +00006789- sets and frozensets now have an isdisjoint() method.

6794
Georg Brandl21e99f42010-03-07 15:23:59 +00006795- The enumerate() built-in function is no longer bounded to sequences
Georg Brandl3ee81df2008-05-17 18:14:43 +00006796 smaller than LONG_MAX. Formerly, it raised an OverflowError. Now,
6797 automatically shifts from ints to longs.
Raymond Hettinger8f669372007-10-03 21:18:11 +00006798
Georg Brandl3ee81df2008-05-17 18:14:43 +00006799- Issue #1686386: Tuple's tp_repr did not take into account the
6800 possibility of having a self-referential tuple, which is possible
6801 from C code. Nor did object's tp_str consider that a type's tp_str
6802 could do something that could lead to an inifinite recursion.
6803 Py_ReprEnter() and Py_EnterRecursiveCall(), respectively, fixed the
6804 issues.
Brett Cannon0b14f242007-09-30 19:45:10 +00006805
Georg Brandl3ee81df2008-05-17 18:14:43 +00006806- Issue #1164: It was possible to trigger deadlock when using the
6807 'print' statement to write to a file since the GIL was not released
6808 as needed. Now PyObject_Print() does the right thing along with
6809 various tp_print implementations of the built-in types and those in
6810 the collections module.
Brett Cannon01531592007-09-17 03:28:34 +00006811
Georg Brandl3ee81df2008-05-17 18:14:43 +00006812- Issue #1147: Exceptions were directly allowing string exceptions in
6813 their throw() method even though string exceptions no longer
6814 allowed.
Brett Cannon4c20bc42007-09-11 21:02:28 +00006815
Georg Brandl3ee81df2008-05-17 18:14:43 +00006816- Issue #1096: Prevent a segfault from getting the repr of a very
6817 deeply nested list by using the recursion counter.
Brett Cannona0c05512007-09-10 21:38:27 +00006818
Brett Cannon1e534b52007-09-07 04:18:30 +00006819- Issue #1202533: Fix infinite recursion calls triggered by calls to
Georg Brandl3ee81df2008-05-17 18:14:43 +00006820 PyObject_Call() never calling back out to Python code to trigger
6821 recursion depth updates/checks. Required the creation of a static
6822 RuntimeError instance in case normalizing an exception put the
6823 recursion check value past its limit. Fixes crashers
6824 infinite_rec_(1|2|4|5).py.
Brett Cannon1e534b52007-09-07 04:18:30 +00006825
Georg Brandl3ee81df2008-05-17 18:14:43 +00006826- Patch #1031213: Decode source line in SyntaxErrors back to its

Neal Norwitz0ac60192007-05-27 04:08:54 +00006839- Add new attribute names for function objects. All the func_* become
Georg Brandl3ee81df2008-05-17 18:14:43 +00006840 __*__ attributes. (Some already existed, e.g., __doc__ and
6841 __name__.)
Neal Norwitz0ac60192007-05-27 04:08:54 +00006842
Neal Norwitz8b2bfbc2007-05-23 06:35:32 +00006843- Add -3 option to the interpreter to warn about features that are
6844 deprecated and will be changed/removed in Python 3.0.
6845
Georg Brandl2134e752007-05-21 20:34:16 +00006846- Patch #1686487: you can now pass any mapping after '**' in function
6847 calls.
6848
Collin Winter62903052007-05-18 23:11:24 +00006849- except clauses may now be spelled either "except E, target:" or
Georg Brandl3ee81df2008-05-17 18:14:43 +00006850 "except E as target:". This is to provide forwards compatibility
6851 with Python 3.0.
Collin Winter62903052007-05-18 23:11:24 +00006852
Brett Cannon229cee22007-05-05 01:34:02 +00006853- Deprecate BaseException.message as per PEP 352.
6854
Georg Brandl3ee81df2008-05-17 18:14:43 +00006855- Issue #1303614: don't expose object's __dict__ when the dict is
Georg Brandl21e99f42010-03-07 15:23:59 +00006856 inherited from a built-in base.
Armin Rigo9790a272007-05-02 19:23:31 +00006857
Vinay Sajip8549ce32007-05-06 17:53:37 +00006858- When __slots__ are set to a unicode string, make it work the same as
Neal Norwitzcbd9ee62007-04-14 05:25:50 +00006859 setting a plain string, ie don't expand to single letter identifiers.
6860
Raymond Hettinger13936692007-04-11 18:40:58 +00006861- Request #1191699: Slices can now be pickled.
6862
Raymond Hettinger4db5fe92007-04-12 04:10:00 +00006863- Request #1193128: str.translate() now allows a None argument for
6864 translations that only remove characters without re-mapping the
6865 remaining characters.
6866
Georg Brandl5cb76c12007-03-21 09:00:39 +00006867- Patch #1682205: a TypeError while unpacking an iterable is no longer
6868 masked by a generic one with the message "unpack non-sequence".
6869
Neal Norwitzaa754b72007-03-21 06:39:48 +00006870- Remove unused file Python/fmod.c.
6871
Guido van Rossum143b5642007-03-23 04:58:42 +00006872- Bug #1683368: The object.__init__() and object.__new__() methods are
6873 now stricter in rejecting excess arguments. The only time when
6874 either allows excess arguments is when it is not overridden and the
6875 other one is. For backwards compatibility, when both are
6876 overridden, it is a deprecation warning (for now; maybe a Py3k
Guido van Rossum234b1ff2007-03-23 19:39:01 +00006877 warning later). Also, type.__init__() insists on the same signature
6878 as supported by type.__new__().
Guido van Rossum143b5642007-03-23 04:58:42 +00006879
Georg Brandl3ee81df2008-05-17 18:14:43 +00006880- Patch #1675423: PyComplex_AsCComplex() now tries to convert an
6881 object to complex using its __complex__() method before falling back
6882 to the __float__() method. Therefore, the functions in the cmath
6883 module now can operate on objects that define a __complex__()
6884 method.
Georg Brandl2b869942007-03-17 16:08:45 +00006885
Georg Brandl3ee81df2008-05-17 18:14:43 +00006886- Patch #1623563: allow __class__ assignment for classes with
6887 __slots__. The old and the new class are still required to have the
6888 same slot names.
Žiga Seilnacht6f2d09c2007-03-16 11:59:38 +00006889
Georg Brandl3ee81df2008-05-17 18:14:43 +00006890- Patch #1642547: Fix an error/crash when encountering syntax errors

6894 ``object.__reduce_ex__()`` is called with an object that is faking
6895 its type.
Žiga Seilnacht20f43d32007-03-15 11:44:55 +00006896
Georg Brandl3ee81df2008-05-17 18:14:43 +00006897- Patch #1680015: Don't modify __slots__ tuple if it contains an

6901
Georg Brandl7b9c5552007-03-12 14:30:05 +00006902- Bug #1678647: write a newline after printing an exception in any
6903 case, even when converting the value to a string failed.
6904
Georg Brandl871f1bc2007-03-12 13:17:36 +00006905- The dir() function has been extended to call the __dir__() method on
Georg Brandl3ee81df2008-05-17 18:14:43 +00006906 its argument, if it exists. If not, it will work like before. This
6907 allows customizing the output of dir() in the presence of a
6908 __getattr__().
Georg Brandl871f1bc2007-03-12 13:17:36 +00006909
Collin Winter276887b2007-03-12 16:11:39 +00006910- Patch #922167: Python no longer segfaults when faced with infinitely
6911 self-recursive reload() calls (as reported by bug #742342).
6912
Georg Brandl3ee81df2008-05-17 18:14:43 +00006913- Patch #1675981: remove unreachable code from ``type.__new__()``
6914 method.

Georg Brandl3ee81df2008-05-17 18:14:43 +00006916- Patch #1491866: change the complex() constructor to allow
6917 parthensized forms. This means complex(repr(x)) now works instead of
6918 raising a ValueError.
Collin Wintere38051d2007-03-09 20:33:07 +00006919
Georg Brandlaa2321b2007-03-07 00:40:28 +00006920- Patch #703779: unset __file__ in __main__ after running a file. This
Georg Brandl3ee81df2008-05-17 18:14:43 +00006921 makes the filenames the warning module prints much more sensible
6922 when a PYTHONSTARTUP file is used.
Georg Brandlaa2321b2007-03-07 00:40:28 +00006923

6925 exception if the -i command line option or PYTHONINSPECT environment
Georg Brandl3ee81df2008-05-17 18:14:43 +00006926 variable is given, but break into the interactive interpreter just
6927 like on other exceptions or normal program exit.

Georg Brandl098cd692007-03-06 12:17:50 +00006934
Georg Brandl0fca97a2007-03-05 22:28:08 +00006935- Patch #1674228: when assigning a slice (old-style), check for the
6936 sq_ass_slice instead of the sq_slice slot.
6937
Georg Brandl3ee81df2008-05-17 18:14:43 +00006938- When printing an unraisable error, don't print exceptions. before
6939 the name. This duplicates the behavior whening normally printing
6940 exceptions.

Georg Brandl3ee81df2008-05-17 18:14:43 +00007491- Patch #1530482: add pydoc.render_doc() which returns the

7506
Georg Brandl92a6bae2007-03-13 17:43:32 +00007507- Patch #1603688: ConfigParser.SafeConfigParser now checks values that
Georg Brandl3ee81df2008-05-17 18:14:43 +00007508 are set for invalid interpolation sequences that would lead to
7509 errors on reading back those values.

7565 TestCase and TestSuite subclasses (not instances) are no longer
7566 accepted in TestSuite.addTest(). This should cause no
7567 incompatibility since it never made sense with ordinary subclasses
7568 -- the failure just occurred later, with a more cumbersome
7569 exception.

Gregory P. Smithbde4ae42008-01-17 08:35:49 +00007856 that the SMTP.starttls() caller no longer needs to call ehlo()

Gregory P. Smithec10a4a2007-11-05 02:32:26 +00007957- pybsddb.sf.net Bug #477182: Load the database flags at database open
Georg Brandl3ee81df2008-05-17 18:14:43 +00007958 time so that opening a database previously created with the DB_DUP
7959 or DB_DUPSORT flag set will keep the proper behavior on subsequent
7960 opens. Specifically: dictionary assignment to a DB object will
7961 replace all values for a given key when the database allows
7962 duplicate values. DB users should use DB.put(k, v) when they want
7963 to store duplicates; not DB[k] = v.

Raymond Hettingerdc1d1ba2007-11-07 02:45:46 +00008242- Add a FAST_LOOPS build option that speeds-up looping by trading away
Georg Brandl3ee81df2008-05-17 18:14:43 +00008243 periodic threadstate and signal checking in tight loops. By
8244 default, this option is turned-off. It should only be enabled in
8245 debugged, performance critical applications.

Georg Brandl3ee81df2008-05-17 18:14:43 +00008303- ``PySet_Add()`` can now modify a newly created frozenset. Similarly
8304 to ``PyTuple_SetItem``, it can be used to populate a brand new

8317
Georg Brandl3ee81df2008-05-17 18:14:43 +00008318- Issue #1521: On 64bit platforms, using PyArgs_ParseTuple with the t#
8319 of w# format code incorrectly truncated the length to an int, even
8320 when PY_SSIZE_T_CLEAN is set. The str.decode method used to return
8321 incorrect results with huge strings.
Georg Brandl6caad7d2008-01-26 14:19:22 +00008322

8349 imports under some conditions.
Christian Heimes000a0742008-01-03 22:16:32 +00008350
Georg Brandl3ee81df2008-05-17 18:14:43 +00008351- Added case insensitive comparison methods ``PyOS_stricmp(char*,
8352 char*)`` and ``PyOS_strnicmp(char*, char*, Py_ssize_t)``.
Christian Heimes000a0742008-01-03 22:16:32 +00008353
Georg Brandl3ee81df2008-05-17 18:14:43 +00008354- Bug #1542693: remove semi-colon at end of PyImport_ImportModuleEx
