754 int.__pow__. These overflow checks were causing int.__pow__ to produce
755 incorrect results with recent versions of Clang, as a result of the
Mark Dickinsona96b0d12011-09-24 09:01:16 +0100756 compiler optimizing the check away. Also fix similar overflow checks
757 in list_repeat (listobject.c) and islice_next (itertoolsmodule.c). These

771 and its type get caught in a reference cycle, and the instance's
772 deallocator calls one of the methods on the type (e.g. when subclassing

Ned Deily0d0ea482012-02-10 12:59:06 +0100833- Issue #13590: On OS X 10.7 and 10.6 with Xcode 4.2, building
834 Distutils-based packages with C extension modules may fail because
835 Apple has removed gcc-4.2, the version used to build python.org
836 64-bit/32-bit Pythons. If the user does not explicitly override
837 the default C compiler by setting the CC environment variable,
838 Distutils will now attempt to compile extension modules with clang
839 if gcc-4.2 is required but not found. Also as a convenience, if
840 the user does explicitly set CC, substitute its value as the default
841 compiler in the Distutils LDSHARED configuration variable for OS X.
842 (Note, the python.org 32-bit-only Pythons use gcc-4.0 and the 10.4u
843 SDK, neither of which are available in Xcode 4. This change does not
844 attempt to override settings to support their use with Xcode 4.)

Ned Deily87e82bb2011-06-28 19:52:59 -07001117- Issue #9516: On Mac OS X, change Distutils to no longer globally attempt to
1118 check or set the MACOSX_DEPLOYMENT_TARGET environment variable for the
1119 interpreter process. This could cause failures in non-Distutils subprocesses
1120 and was unreliable since tests or user programs could modify the interpreter
1121 environment after Distutils set it. Instead, have Distutils set the the
1122 deployment target only in the environment of each build subprocess. It is
1123 still possible to globally override the default by setting
1124 MACOSX_DEPLOYMENT_TARGET before launching the interpreter; its value must be
1125 greater or equal to the default value, the value with which the interpreter
1126 was built.

1156 the ticker doesn't have to wind down to zero from the old starting point
1157 before the new interval takes effect. And if the user increases the
1158 interval, it makes sure the new limit takes effect right away rather have an
1159 early task switch before recognizing the new interval.

2111 This prevents user-created self-referencing ordered dictionaries from
2112 becoming permanently uncollectable GC garbage. The downside is that
2113 removing __del__ means that the internal doubly-linked list has to wait for
2114 GC collection rather than freeing memory immediately when the refcnt drops
2115 to zero.

2959
Philip Jenveyaebbaeb2010-04-06 23:24:45 +00002960- Issue #7301: Add environment variable $PYTHONWARNINGS.
2961
Benjamin Peterson3a1dfa22010-04-06 21:50:00 +00002962- Issue #8329: Don't return the same lists from select.select when no fds are
2963 changed.
2964
Georg Brandlfee0f442010-05-22 21:26:21 +00002965- Issue #8259: ``1L << (2**31)`` no longer produces an 'outrageous shift error'
Mark Dickinson82791672010-04-06 16:47:55 +00002966 on 64-bit machines. The shift count for either left or right shift is
2967 permitted to be up to sys.maxsize.
2968
Benjamin Peterson4ceeeb02010-04-03 22:48:51 +00002969- Ensure that tokenization of identifiers is not affected by locale.

2974
Georg Brandlfee0f442010-05-22 21:26:21 +00002975- Issue #7994: Issue a PendingDeprecationWarning if object.__format__ is called
2976 with a non-empty format string. This is an effort to future-proof user
2977 code. If a derived class does not currently implement __format__ but later
2978 adds its own __format__, it would most likely break user code that had
Antoine Pitrou01a196a2011-01-02 20:05:11 +00002979 supplied a format string. This will be changed to a DeprecationWarning in
Georg Brandlfee0f442010-05-22 21:26:21 +00002980 Python 3.3 and it will be an error in Python 3.4.

Georg Brandlfee0f442010-05-22 21:26:21 +00003013- Issue #8257: The Decimal construct now accepts a float instance directly,
3014 converting that float to a Decimal of equal value:
Mark Dickinson8a950712010-04-03 15:47:46 +00003015

3018
Raymond Hettinger34c35b22010-04-03 10:22:00 +00003019- collections.Counter() now supports a subtract() method.

Georg Brandlfee0f442010-05-22 21:26:21 +00003021- The functools module now has a total_ordering() class decorator to simplify

Georg Brandlfee0f442010-05-22 21:26:21 +00003030- Issue #7279: Comparisons involving a Decimal signaling NaN now signal
3031 InvalidOperation instead of returning False. (Comparisons involving a quiet
3032 NaN are unchanged.) Also, Decimal quiet NaNs are now hashable; Decimal
3033 signaling NaNs remain unhashable.
Mark Dickinsone096e822010-04-02 10:17:07 +00003034
Georg Brandlfee0f442010-05-22 21:26:21 +00003035- Issue #2531: Comparison operations between floats and Decimal instances now
3036 return a result based on the numeric values of the operands; previously they
3037 returned an arbitrary result based on the relative ordering of id(float) and
3038 id(Decimal).

Barry Warsawf7f2d6f2010-03-31 21:07:16 +00003040- Issue #8233: When run as a script, py_compile.py optionally takes a single
Georg Brandlfee0f442010-05-22 21:26:21 +00003041 argument `-` which tells it to read files to compile from stdin. Each line is
3042 read on demand and the named file is compiled immediately. (Original patch by

Georg Brandlfee0f442010-05-22 21:26:21 +00003052- Comparisons using one of <, <=, >, >= between a complex instance and a
3053 Fractions instance now raise TypeError instead of returning True/False. This
3054 makes Fraction <=> complex comparisons consistent with int <=> complex, float
3055 <=> complex, and complex <=> complex comparisons.

3164 the set of integer codes for which it was used differed between native packing
3165 and standard packing.)

Georg Brandlba83f822010-03-14 09:50:54 +00003473 file position when calling `truncate()`. It would previously change the file
3474 position to the given argument, which goes against the tradition of
Antoine Pitrouf3fa0742010-01-31 22:26:04 +00003475 ftruncate() and other truncation APIs. Patch by Pascal Chambon.

3478 class used to represent files stored inside an archive. The new
3479 implementation is significantly faster and can be wrapped in a

3481 where interleaved calls to ``read()`` and ``readline()`` give wrong results.

3494 encoded string for them. This ensures that the upload and register commands
3495 send the correct values to PyPI without any error.

Mark Dickinson1b34d252010-01-01 17:27:30 +00003578- Issue #5080: A number of functions and methods previously produced a

3580 These functions and methods now raise TypeError instead. The majority of the
3581 effects of this change are in the extension modules, but some core functions
3582 and methods are affected: notably the 'chr', 'range' and 'xrange' builtins,
3583 and many unicode/str methods.

Georg Brandlba83f822010-03-14 09:50:54 +00003766- Issue #7117: ``repr(x)`` for a float x returns a result based on the shortest
3767 decimal string that's guaranteed to round back to x under correct rounding
3768 (with round-half-to-even rounding mode). Previously it gave a string based on
3769 rounding x to 17 decimal digits. repr(x) for a complex number behaves
3770 similarly. On platforms where the correctly-rounded strtod and dtoa code is
3771 not supported (see below), repr is unchanged.
Mark Dickinsonb678de82009-11-19 18:41:49 +00003772
Georg Brandlba83f822010-03-14 09:50:54 +00003773- Issue #7117: On almost all platforms: float-to-string and string-to-float
3774 conversions within Python are now correctly rounded. Places these conversions
3775 occur include: str for floats and complex numbers; the float and complex
3776 constructors; old-style and new-style numeric formatting; serialization and
3777 deserialization of floats and complex numbers using marshal, pickle and json;
3778 parsing of float and imaginary literals in Python code; Decimal-to-float
3779 conversion.
Mark Dickinsonb678de82009-11-19 18:41:49 +00003780
Georg Brandlba83f822010-03-14 09:50:54 +00003781 The conversions use a Python-adapted version of David Gay's well-known dtoa.c,
3782 providing correctly-rounded strtod and dtoa C functions. This code is
3783 supported on Windows, and on Unix-like platforms using gcc, icc or suncc as
3784 the C compiler. There may be a small number of platforms on which correct
3785 operation of this code cannot be guaranteed, so the code is not used: notably,
3786 this applies to platforms where the C double format is not IEEE 754 binary64,
3787 and to platforms on x86 hardware where the x87 FPU is set to 64-bit precision
3788 and Python's configure script is unable to determine how to change the FPU
3789 precision. On these platforms conversions use the platform strtod and dtoa,
3790 as before.

Georg Brandlba83f822010-03-14 09:50:54 +00003792- Issue #7117: Backport round implementation from Python 3.x. ``round()`` now
3793 uses the correctly-rounded string <-> float conversions described above (when
3794 available), and so produces correctly rounded results that will display nicely
3795 under the float repr. There are two related small changes: (1) round now
3796 accepts any class with an ``__index__()`` method for its second argument (but
3797 no longer accepts floats for the second argument), and (2) an excessively
3798 large second integer argument (e.g., ``round(1.234, 10**100)``) no longer
3799 raises an exception.

4178 this code path is really executed because I cannot move to such directory on
4179 win2k)

4205 PyUnicode_DecodeUTF8() once, remember the result and output it in a second

5581
Amaury Forgeot d'Arc05e34492008-09-10 22:04:45 +00005582- Issue #3743: In a few places, PY_FORMAT_SIZE_T was incorrectly used with
5583 PyString_FromFormat or PyErr_Format to display size_t values. The macro
5584 PY_FORMAT_SIZE_T is designed to select the correct format for the OS
5585 ``printf`` function, whereas PyString_FromFormat has an independent
5586 implementation and uses "%zd" on all platforms for size_t values.
5587 This makes a difference on win64, where ``printf`` needs "%Id" to display
5588 64bit values.

Antoine Pitrou0668c622008-08-26 22:42:08 +00005608 match Python 2.5 speed despite the __instancecheck__ / __subclasscheck__
5609 mechanism. In the process, fix a bug where isinstance() and issubclass(),

5611 __instancecheck__ / __subclasscheck__ on the tuple rather than on each
5612 type object.

Brett Cannon1eaf0742008-09-02 01:25:16 +00005683 warnings.catch_warnings() along with some API cleanup. Expanding the tests
5684 for catch_warnings() also led to an improvement in the raising of a
5685 DeprecationWarning related to warnings.warn_explicit().
5686
Benjamin Peterson973e6c22008-09-01 23:12:58 +00005687- The deprecation warnings for the old camelCase threading API were removed.

5709
Amaury Forgeot d'Arc293924b2008-09-02 23:19:56 +00005710- Issue #2975: When compiling several extension modules with Visual Studio 2008
5711 from the same python interpreter, some environment variables would grow
5712 without limit.
5713
Benjamin Peterson37346b22008-08-23 20:27:43 +00005714- Issue #3643: Added a few more checks to _testcapi to prevent segfaults by
5715 exploitation of poor argument checking.
5716
Gerhard Häringef2276b2008-09-12 13:54:06 +00005717- sqlite3: Changed docstring of iterdump() to mark method as "Non-standard".

5730 wrapper for warnings.catch_warnings() that makes it easier to check
5731 that expected warning messages are being reported.
5732

Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00005751What's New in Python 2.6 beta 3?
5752================================
5753
Barry Warsaw07a4a382008-08-21 01:15:08 +00005754*Release date: 20-Aug-2008*
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00005755
5756Core and Builtins
5757-----------------
5758
Guido van Rossumf8402962008-08-20 15:01:50 +00005759- Issue #1878: Remove Py_TPFLAGS_HAVE_VERSION_TAG from
5760 Py_TPFLAGS_DEFAULT when not building the core. This means 3rd party
5761 extensions do not automatically benefit from the class attribute
5762 cache; they will have to explicitly add Py_TPFLAGS_HAVE_VERSION_TAG
5763 to their tp_flags field if they care. This is a backwards
5764 compatibility feature; in 3.0, all types will use the cache by
5765 default.
5766
Benjamin Petersonf647dc12008-08-20 01:27:30 +00005767- Keyword arguments can now follow starred arguments. (``f(a, *args,
5768 keyword=23)`` is now valid syntax.)
5769
Thomas Heller0ad5ae02008-08-19 19:25:04 +00005770- ctypes function pointers that are COM methods have a boolean True
5771 value again.
5772
Martin v. Löwisf91d46a2008-08-12 14:49:50 +00005773- Issue #3139: Make buffer-interface thread-safe wrt. PyArg_ParseTuple,
5774 by denying s# to parse objects that have a releasebuffer procedure,
5775 and introducing s*.
5776
Georg Brandl1e13ea92008-08-11 09:07:59 +00005777- Issue #3537: Fix an assertion failure when an empty but presized dict
5778 object was stored in the freelist.
5779
Mark Dickinsonb6467572008-08-04 21:30:09 +00005780- Issue #1481296: Make long(float('nan')) and int(float('nan')) raise
5781 ValueError consistently across platforms.
5782
Amaury Forgeot d'Arc39fd6722008-07-31 21:28:03 +00005783- Issue #3479: On platforms where sizeof(int) is smaller than sizeof(long)
5784 (64bit Unix, for example), unichr() would truncate its argument and return
5785 u'\x00' for unichr(2**32). Now it properly raises an OverflowError.
5786
Neal Norwitze7d8be82008-07-31 17:17:14 +00005787- Apply security patches from Apple.
5788
Amaury Forgeot d'Arc246daed2008-07-31 00:42:16 +00005789- Issue #2542: Now that issubclass() may call arbitrary code, ensure that
5790 PyErr_ExceptionMatches returns 0 when an exception occurs there.
5791
Antoine Pitrou92f82162008-07-25 22:22:08 +00005792- Issue #1819: function calls with several named parameters are now on
5793 average 35% faster (as measured by pybench).
5794
Amaury Forgeot d'Arce4921fe2008-07-21 22:00:38 +00005795- Issue #2378: An unexpected UnboundLocalError or NameError could appear when
5796 the python debugger steps into a class statement: the free variables (local
5797 variables defined in an outer scope) would be deleted from the outer scope.
5798
Gregory P. Smith0470bab2008-07-22 04:46:32 +00005799- Issue #2620: Overflow checking when allocating or reallocating memory
5800 was not always being done properly in some python types and extension
5801 modules. PyMem_MALLOC, PyMem_REALLOC, PyMem_NEW and PyMem_RESIZE have
5802 all been updated to perform better checks and places in the code that
5803 would previously leak memory on the error path when such an allocation
5804 failed have been fixed.
5805

5807-------
5808
Hirokazu Yamamoto838c79f2008-08-20 13:14:07 +00005809- Issue #3612: Added some missing basic types in ctypes.wintypes.
5810
Benjamin Petersone977ad42008-08-20 01:42:01 +00005811- The methods ``is_in_tuple()``, ``is_vararg()``, and ``is_keywordarg()`` of
5812 symtable.Symbol have been deprecated for removal in 3.0 and the next release.
5813
Amaury Forgeot d'Arc351ffb82008-08-18 19:23:47 +00005814- Issue #2234: distutils failed for some versions of the cygwin compiler. The
5815 version reported by these tools does not necessarily follow the python
5816 version numbering scheme, so the module is less strict when parsing it.
5817
Nick Coghlanf70385a2008-08-18 12:42:46 +00005818- Issue #2235: Added Py3k warnings for types which will become unhashable
5819 under the stricter __hash__ inheritance rules in 3.0. Several types
5820 which did not meet the rules for hash invariants and were already
5821 unhashable in 3.0 have now been explicitly flagged as unhashable in
5822 2.6 as well (collections.Mapping, collections.Set, unittest.TestSuite,
5823 xml.dom.minidom.NamedNodeMap, numbers.Number, UserList.UserList)
5824
Brett Cannon88f801d2008-08-18 00:46:22 +00005825- Update __all__ for cookielib, csv, os, urllib2, and weakref to include things
5826 imported into the module but exposed as part of the module's API.
5827
Brett Cannon7b96f072008-08-18 00:41:11 +00005828- Remove an unneeded import of abc.ABCMeta from 'inspect'.

Brett Cannon25c9d6a2008-08-17 22:10:11 +00005832- Remove unneeded imports of 'warnings' from shelve, filecmp, and dummy_thread.
5833
Hirokazu Yamamoto41a81eb2008-08-17 13:10:46 +00005834- Issue #3575: Incremental decoder's decode function now takes bytearray
5835 by using 's*' instead of 't#'.
5836
Mark Dickinson3e4caeb2009-02-21 20:27:01 +00005837- Issue #2222: Fixed reference leak when occurred os.rename()
Hirokazu Yamamoto7f30a682008-08-17 09:46:56 +00005838 fails unicode conversion on 2nd parameter. (windows only)
5839
Georg Brandl222e2082010-08-01 22:27:39 +00005840- Issue #2464: urllib2 now supports a malformation in the URL received
Facundo Batista94f243a2008-08-17 03:38:39 +00005841 in a redirect.
5842
Brett Cannonabe423e2008-08-16 21:47:07 +00005843- Silence the DeprecationWarning raised when importing mimetools in
Brett Cannon721b1452008-08-16 22:00:27 +00005844 BaseHTTPServer, cgi (and rfc822), httplib.
Brett Cannonabe423e2008-08-16 21:47:07 +00005845
Facundo Batistaeb90b782008-08-16 14:44:07 +00005846- Issue #2776: fixed small issue when handling an URL with double slash
5847 after a 302 response in the case of not going through a proxy.
5848
Antoine Pitroub90a8be2008-08-15 21:03:21 +00005849- Issue #2676: in the email package, content-type parsing was hanging on
5850 pathological input because of quadratic or exponential behaviour of a
5851 regular expression.
5852
Antoine Pitrou11ec65d2008-08-14 21:04:30 +00005853- Issue #3476: binary buffered reading through the new "io" library is now
5854 thread-safe.
5855
Brett Cannonbf3157b2008-08-14 05:00:03 +00005856- Silence the DeprecationWarning of rfc822 when it is imported by mimetools
5857 since mimetools itself is deprecated. Because modules are cached, all
5858 subsequent imports of rfc822 will not raise a visible DeprecationWarning.
5859
Antoine Pitrou9fcd4b32008-08-11 17:21:36 +00005860- Issue #3134: shutil referenced undefined WindowsError symbol.
5861
Robert Schuppenies14646332008-08-10 11:01:53 +00005862- Issue #1342811: Fix leak in Tkinter.Menu.delete. Commands associated to
5863 menu entries were not deleted.
5864
Brett Cannon83e81842008-08-09 23:30:55 +00005865- Copied the implementation of reduce() to _functools.reduce() to have a
5866 version that did not raise a DeprecationWarning under -3.
5867
Antoine Pitrou76b8bee2008-08-09 17:27:23 +00005868- Issue #3205: When iterating over a BZ2File fails allocating memory, raise
5869 a MemoryError rather than silently stop the iteration.
5870
Guido van Rossum59ce9012008-08-09 14:55:34 +00005871- Issue #3487: sre "bytecode" validator. Passing invalid "re-bytecode"
5872 to _sre.compile() will now be rejected. This should not affect anybody
5873 since the re.compile() function never generates invalid re-bytecode.
5874
Skip Montanaroa032bf42008-08-08 22:52:51 +00005875- Issue #3436: Make csv.DictReader's fieldnames attribute a property so that
5876 upon first access it can be automatically initialized from the csv file if
5877 it wasn't initialized during instantiation.
5878
Brett Cannon3aa2a492008-08-06 22:28:09 +00005879- Issue #2338: Create imp.reload() to help with transitioning to Python 3.0 as
5880 the reload() built-in has been removed.
5881
Brett Cannon7e30b672008-08-04 21:52:25 +00005882- Changed code in the following modules/packages to remove warnings raised
Brett Cannonc1b76e42008-08-09 23:06:16 +00005883 while running under the ``-3`` flag: aifc, asynchat, asyncore, bdb, bsddb,

Antoine Pitroude781a42008-08-09 12:43:23 +00005894 asking for a specific length. This problem only affected files opened
5895 using the new "io" module, not the built-in open() function.
Benjamin Peterson01a24322008-07-28 23:35:27 +00005896

5921 file name rather than a ZipInfo instance, so files are extracted with
5922 mode 0600 rather than 000 under Unix.
5923

5941 regarding lack of coverage of new-style classes have also been
5942 removed, since the coverage is now fairly reasonable.

5952
Georg Brandl3e483f62008-07-16 22:57:41 +00005953- Issue #3156: Fix inconsistent behavior of the bytearray type: all
5954 its methods now allow for items objects that can be converted to
5955 an integer using operator.index().
5956
Mark Dickinson64b7e502008-07-16 09:40:03 +00005957- Issue #3360: Fix incorrect parsing of '020000000000.0', which
5958 produced a ValueError instead of giving the correct float.
5959
Eric Smitha5fa5a22008-07-16 00:11:49 +00005960- Issue #3083: Add alternate (#) formatting for bin, oct, hex output

5965 numbers to and from hexadecimal strings, respectively.
5966
Nick Coghlan6d6bd442008-07-15 15:40:22 +00005967- Issue #2235: __hash__ is once again inherited by default. To allow
5968 collections.Hashable to remain meaningful in the presence of the
5969 default hash implementation (object.__hash__), it is now possible
5970 to explicit block inheritance of hash by setting __hash__=None at
5971 the Python level, or tp_hash=PyObject_HashNotImplemented at the C
5972 level.
5973
Nick Coghlanb028f502008-07-13 14:52:36 +00005974- Issue #3221: Issue a RuntimeWarning instead of raising SystemError if
5975 the parent module cannot be found while performing an absolute import.
5976 This means that an incorrectly defined __package__ attribute will
5977 now only prevent relative imports in that module rather than causing
5978 all imports from that module to fail.
5979
Nick Coghlan14ff9942008-07-08 14:21:42 +00005980- Issue #2517: Allow unicode messages in Exceptions again by correctly

5991
Mark Dickinson1ec2fcd2008-06-20 14:53:43 +00005992- Issue #3004: Minor change to slice.indices(): the start and stop
5993 arguments are now treated identically, making the behaviour easier
5994 to describe and understand. For example, slice(None, -10,
5995 1).indices(9) now returns (0, 0, 1) instead of (0, -1, 1), and
5996 slice(None, 10, -1).indices(10) returns (9, 9, -1) instead of (9,
5997 10, -1).

6040 both unnecessary (HTTP allows text content to be sent in several forms) and
Andrew M. Kuchlingcc3f2b12008-07-10 14:43:31 +00006041 wrong because the actual transmitted size could differ from the

Georg Brandl3ee81df2008-05-17 18:14:43 +00006513- Issue #1631171: Re-implement the 'warnings' module in C (the
6514 original Python code has been kept as backup). This will allow for
6515 using the 'warning's machinery in such places as the parser where
6516 use of pure Python code is not possible. Both the ``showarning()``
6517 and ``formatwarning()`` gain an optional 'line' argument which is

Georg Brandl3ee81df2008-05-17 18:14:43 +00006583- Issue #2550: The approach used by client/server code for obtaining
6584 ports to listen on in network-oriented tests has been refined in an
6585 effort to facilitate running multiple instances of the entire
6586 regression test suite in parallel without issue.
6587 test_support.bind_port() has been fixed such that it will always
6588 return a unique port -- which wasn't always the case with the
6589 previous implementation, especially if socket options had been set
6590 that affected address reuse (i.e. SO_REUSEADDR, SO_REUSEPORT). The
6591 new implementation of bind_port() will actually raise an exception
6592 if it is passed an AF_INET/SOCK_STREAM socket with either the
6593 SO_REUSEADDR or SO_REUSEPORT socket option set. Furthermore, if
6594 available, bind_port() will set the SO_EXCLUSIVEADDRUSE option on
6595 the socket it's been passed. This currently only applies to
6596 Windows. This option prevents any other sockets from binding to the
6597 host/port we've bound to, thus removing the possibility of the
6598 'non-deterministic' behaviour, as Microsoft puts it, that occurs
6599 when a second SOCK_STREAM socket binds and accepts to a host/port
6600 that's already been bound by another socket. The optional preferred
6601 port parameter to bind_port() has been removed. Under no
6602 circumstances should tests be hard coding ports!
6603
6604 test_support.find_unused_port() has also been introduced, which will
6605 pass a temporary socket object to bind_port() in order to obtain an
6606 unused port. The temporary socket object is then closed and
6607 deleted, and the port is returned. This method should only be used
6608 for obtaining an unused port in order to pass to an external program
6609 (i.e. the -accept [port] argument to openssl's s_server mode) or as
6610 a parameter to a server-oriented class that doesn't give you direct
6611 access to the underlying socket used.
6612
6613 Finally, test_support.HOST has been introduced, which should be used
6614 for the host argument of any relevant socket calls (i.e. bind and
6615 connect).
Trent Nelsone41b0062008-04-08 23:47:30 +00006616
6617 The following tests were updated to following the new conventions:
Georg Brandl3ee81df2008-05-17 18:14:43 +00006618 test_socket, test_smtplib, test_asyncore, test_ssl, test_httplib,
Trent Nelsone41b0062008-04-08 23:47:30 +00006619 test_poplib, test_ftplib, test_telnetlib, test_socketserver,
6620 test_asynchat and test_socket_ssl.
6621
Georg Brandl3ee81df2008-05-17 18:14:43 +00006622 It is now possible for multiple instances of the regression test
6623 suite to run in parallel without issue.

6790 values on 32-bit vs. 64-bit python interpreters. Both were correct,
6791 but they now both return a signed integer object for consistency.

Eric Smitha73fbe72008-02-23 03:09:44 +00006902- Added the future_builtins module, which contains hex() and oct().
6903 These are the PEP 3127 version of these functions, designed to be
6904 compatible with the hex() and oct() builtins from Python 3.0. They
6905 differ slightly in their output formats from the existing, unchanged
6906 Python 2.6 builtins. The expected usage of the future_builtins
6907 module is:
6908 from future_builtins import hex, oct
6909
Eric Smith7ef40bf2008-02-20 23:34:22 +00006910- Issue #1600: Modifed PyOS_ascii_formatd to use at most 2 digit
6911 exponents for exponents with absolute value < 100. Follows C99
6912 standard. This is a change on Windows, which would use 3 digits.
6913 Also, added 'n' to the formats that PyOS_ascii_formatd understands,
6914 so that any alterations it does to the resulting string will be
6915 available in stringlib/formatter.h (for float.__format__).
6916
Eric Smith5a3c1352008-02-19 13:21:56 +00006917- Implemented PEP 3101, Advanced String Formatting. This adds a new
6918 builtin format(); a format() method for str and unicode; a
6919 __format__() method to object, str, unicode, int, long, float, and
6920 datetime; the class string.Formatter; and the C API
6921 PyObject_Format().
6922
Georg Brandl3ee81df2008-05-17 18:14:43 +00006923- Fixed several potential crashes, all caused by specially crafted
6924 __del__ methods exploiting objects in temporarily inconsistent
6925 state.
Amaury Forgeot d'Arc632fad32008-02-16 20:55:24 +00006926
Vinay Sajipb7edfc42008-04-02 21:10:23 +00006927- Issue #2115: Important speedup in setting __slot__ attributes. Also
Georg Brandl3ee81df2008-05-17 18:14:43 +00006928 prevent a possible crash: an Abstract Base Class would try to access
6929 a slot on a registered virtual subclass.
Amaury Forgeot d'Arc60d6c7f2008-02-15 21:22:45 +00006930

Georg Brandl3ee81df2008-05-17 18:14:43 +00006934- Clear all free lists during a gc.collect() of the highest generation
6935 in order to allow pymalloc to free more arenas. Python may give back
6936 memory to the OS earlier.
Christian Heimes3b718a72008-02-14 12:47:33 +00006937
Georg Brandl3ee81df2008-05-17 18:14:43 +00006938- Issue #2045: Fix an infinite recursion triggered when printing a
6939 subclass of collections.defaultdict, if its default_factory is set
6940 to a bound method.
Amaury Forgeot d'Arcb01aa432008-02-08 00:56:02 +00006941
Christian Heimesf75dbef2008-02-08 00:11:31 +00006942- Fixed a minor memory leak in dictobject.c. The content of the free
6943 list was not freed on interpreter shutdown.
6944
Georg Brandl21e99f42010-03-07 15:23:59 +00006945- Limit free list of method and built-in function objects to 256
Georg Brandl3ee81df2008-05-17 18:14:43 +00006946 entries each.
Christian Heimes6075a822008-02-06 12:44:34 +00006947
Georg Brandl3ee81df2008-05-17 18:14:43 +00006948- Patch #1953: Added ``sys._compact_freelists()`` and the C API
6949 functions ``PyInt_CompactFreeList`` and ``PyFloat_CompactFreeList``
Christian Heimes422051a2008-02-04 18:00:12 +00006950 to compact the internal free lists of pre-allocted ints and floats.
6951
Georg Brandl3ee81df2008-05-17 18:14:43 +00006952- Issue #1983: Fixed return type of fork(), fork1() and forkpty()
6953 calls. Python expected the return type int but the fork familie
6954 returns pi_t.
Christian Heimes951cc0f2008-01-31 23:08:23 +00006955
Georg Brandl3ee81df2008-05-17 18:14:43 +00006956- Issue #1678380: Fix a bug that identifies 0j and -0j when they

6966 the internal lookup cache for ref leak tests.
Christian Heimes908caac2008-01-27 23:34:59 +00006967
Georg Brandl3ee81df2008-05-17 18:14:43 +00006968- Patch #1473257: generator objects gain a gi_code attribute. This is
6969 the same object as the func_code attribute of the function that
6970 produced the generator.
Georg Brandl0cdf9a32008-01-26 14:14:20 +00006971
Georg Brandl3ee81df2008-05-17 18:14:43 +00006972- Issue #1920: "while 0" statements were completely removed by the
6973 compiler, even in the presence of an "else" clause, which is
6974 supposed to be run when the condition is false. Now the compiler
6975 correctly emits bytecode for the "else" suite.
Amaury Forgeot d'Arc31eaafe2008-01-24 22:59:25 +00006976
Guido van Rossumeead05f2008-01-24 18:21:02 +00006977- A few crashers fixed: weakref_in_del.py (issue #1377858);
6978 loosing_dict_ref.py (issue #1303614, test67.py);
6979 borrowed_ref_[34].py (not in tracker).
6980
Vinay Sajipd7cf32e2008-01-24 12:43:33 +00006981- Issue #1069410: The "can't load dll" message box on Windows is
Christian Heimesb2302ba2008-01-23 17:15:06 +00006982 suppressed while an extension is loaded by calling SetErrorMode in

6984
Georg Brandl3ee81df2008-05-17 18:14:43 +00006985- Issue #1915: Python compiles with --enable-unicode=no again. However
Christian Heimes082c9b02008-01-23 14:20:50 +00006986 several extension methods and modules do not work without unicode
6987 support.
6988
Georg Brandl26543b12008-01-21 18:36:51 +00006989- Issue #1882: when compiling code from a string, encoding cookies in the
6990 second line of code were not always recognized correctly.
6991
Georg Brandl14404b62008-01-19 19:27:05 +00006992- Issue #1679: "0x" was taken as a valid integer literal.
6993
Georg Brandl6caad7d2008-01-26 14:19:22 +00006994- Issue #1865: ``bytes`` as an alias for ``str`` and b"" as an alias "" were
Christian Heimes288e89a2008-01-18 18:24:07 +00006995 added.
6996
Christian Heimesc94e2b52008-01-14 04:13:37 +00006997- sys.float_info / PyFloat_GetInfo: The floating point information
6998 object was converted from a dict to a specialized structseq object.
6999
Georg Brandl3ee81df2008-05-17 18:14:43 +00007000- Patch #1816: Added sys.flags structseq. It exposes the status of
7001 most command line arguments and PYTHON* environment variables.
Christian Heimesf31b69f2008-01-14 03:42:48 +00007002
Georg Brandl3ee81df2008-05-17 18:14:43 +00007003- Objects/structseq.c: Implemented new structseq representation. The
7004 patch makes structseqs (e.g. the return value of os.stat) more
7005 readable.
Christian Heimes9c201962008-01-14 03:33:52 +00007006
Georg Brandl3ee81df2008-05-17 18:14:43 +00007007- Patch #1700288: added a type attribute cache that caches method

Georg Brandl3ee81df2008-05-17 18:14:43 +00007029 and INF. float("nan"), float("inf") and float("-inf") now work on
7030 every platform with IEEE 754 semantics.

Georg Brandl3ee81df2008-05-17 18:14:43 +00007032- Compiler now generates simpler and faster code for dictionary
7033 literals. The oparg for BUILD_MAP now indicates an estimated
7034 dictionary size. There is a new opcode, STORE_MAP, for adding
7035 entries to the dictionary.

7047
Nick Coghlanef01d822007-12-03 12:55:17 +00007048- PEP 366: Allow explicit relative imports when executing modules

Georg Brandl3ee81df2008-05-17 18:14:43 +00007064- Patch #1739468: Directories and zipfiles containing a __main__.py
7065 file can now be directly executed by passing their name to the
7066 interpreter. The directory/zipfile is automatically inserted as the
7067 first entry in sys.path.
Nick Coghlan327a39b2007-11-18 11:56:28 +00007068
Georg Brandl3ee81df2008-05-17 18:14:43 +00007069- Issue #1265: Fix a problem with sys.settrace, if the tracing
7070 function uses a generator expression when at the same time the
7071 executed code is closing a paused generator.
Amaury Forgeot d'Arc0d75f092007-11-13 21:54:28 +00007072
Raymond Hettinger1760c8a2007-11-08 02:52:43 +00007073- sets and frozensets now have an isdisjoint() method.

7078
Georg Brandl21e99f42010-03-07 15:23:59 +00007079- The enumerate() built-in function is no longer bounded to sequences
Georg Brandl3ee81df2008-05-17 18:14:43 +00007080 smaller than LONG_MAX. Formerly, it raised an OverflowError. Now,
7081 automatically shifts from ints to longs.
Raymond Hettinger8f669372007-10-03 21:18:11 +00007082
Georg Brandl3ee81df2008-05-17 18:14:43 +00007083- Issue #1686386: Tuple's tp_repr did not take into account the
7084 possibility of having a self-referential tuple, which is possible
7085 from C code. Nor did object's tp_str consider that a type's tp_str
7086 could do something that could lead to an inifinite recursion.
7087 Py_ReprEnter() and Py_EnterRecursiveCall(), respectively, fixed the
7088 issues.
Brett Cannon0b14f242007-09-30 19:45:10 +00007089
Georg Brandl3ee81df2008-05-17 18:14:43 +00007090- Issue #1164: It was possible to trigger deadlock when using the
7091 'print' statement to write to a file since the GIL was not released
7092 as needed. Now PyObject_Print() does the right thing along with
7093 various tp_print implementations of the built-in types and those in
7094 the collections module.
Brett Cannon01531592007-09-17 03:28:34 +00007095
Georg Brandl3ee81df2008-05-17 18:14:43 +00007096- Issue #1147: Exceptions were directly allowing string exceptions in
7097 their throw() method even though string exceptions no longer
7098 allowed.
Brett Cannon4c20bc42007-09-11 21:02:28 +00007099
Georg Brandl3ee81df2008-05-17 18:14:43 +00007100- Issue #1096: Prevent a segfault from getting the repr of a very
7101 deeply nested list by using the recursion counter.
Brett Cannona0c05512007-09-10 21:38:27 +00007102
Brett Cannon1e534b52007-09-07 04:18:30 +00007103- Issue #1202533: Fix infinite recursion calls triggered by calls to
Georg Brandl3ee81df2008-05-17 18:14:43 +00007104 PyObject_Call() never calling back out to Python code to trigger
7105 recursion depth updates/checks. Required the creation of a static
7106 RuntimeError instance in case normalizing an exception put the
7107 recursion check value past its limit. Fixes crashers
7108 infinite_rec_(1|2|4|5).py.
Brett Cannon1e534b52007-09-07 04:18:30 +00007109
Georg Brandl3ee81df2008-05-17 18:14:43 +00007110- Patch #1031213: Decode source line in SyntaxErrors back to its

Neal Norwitz0ac60192007-05-27 04:08:54 +00007123- Add new attribute names for function objects. All the func_* become
Georg Brandl3ee81df2008-05-17 18:14:43 +00007124 __*__ attributes. (Some already existed, e.g., __doc__ and
7125 __name__.)
Neal Norwitz0ac60192007-05-27 04:08:54 +00007126
Neal Norwitz8b2bfbc2007-05-23 06:35:32 +00007127- Add -3 option to the interpreter to warn about features that are
7128 deprecated and will be changed/removed in Python 3.0.
7129
Georg Brandl2134e752007-05-21 20:34:16 +00007130- Patch #1686487: you can now pass any mapping after '**' in function
7131 calls.
7132
Collin Winter62903052007-05-18 23:11:24 +00007133- except clauses may now be spelled either "except E, target:" or
Georg Brandl3ee81df2008-05-17 18:14:43 +00007134 "except E as target:". This is to provide forwards compatibility
7135 with Python 3.0.
Collin Winter62903052007-05-18 23:11:24 +00007136
Brett Cannon229cee22007-05-05 01:34:02 +00007137- Deprecate BaseException.message as per PEP 352.
7138
Georg Brandl3ee81df2008-05-17 18:14:43 +00007139- Issue #1303614: don't expose object's __dict__ when the dict is
Georg Brandl21e99f42010-03-07 15:23:59 +00007140 inherited from a built-in base.
Armin Rigo9790a272007-05-02 19:23:31 +00007141
Vinay Sajip8549ce32007-05-06 17:53:37 +00007142- When __slots__ are set to a unicode string, make it work the same as
Neal Norwitzcbd9ee62007-04-14 05:25:50 +00007143 setting a plain string, ie don't expand to single letter identifiers.
7144
Raymond Hettinger13936692007-04-11 18:40:58 +00007145- Request #1191699: Slices can now be pickled.
7146
Raymond Hettinger4db5fe92007-04-12 04:10:00 +00007147- Request #1193128: str.translate() now allows a None argument for
7148 translations that only remove characters without re-mapping the
7149 remaining characters.
7150
Georg Brandl5cb76c12007-03-21 09:00:39 +00007151- Patch #1682205: a TypeError while unpacking an iterable is no longer
7152 masked by a generic one with the message "unpack non-sequence".
7153
Neal Norwitzaa754b72007-03-21 06:39:48 +00007154- Remove unused file Python/fmod.c.
7155
Guido van Rossum143b5642007-03-23 04:58:42 +00007156- Bug #1683368: The object.__init__() and object.__new__() methods are
7157 now stricter in rejecting excess arguments. The only time when
7158 either allows excess arguments is when it is not overridden and the
7159 other one is. For backwards compatibility, when both are
7160 overridden, it is a deprecation warning (for now; maybe a Py3k
Guido van Rossum234b1ff2007-03-23 19:39:01 +00007161 warning later). Also, type.__init__() insists on the same signature
7162 as supported by type.__new__().
Guido van Rossum143b5642007-03-23 04:58:42 +00007163
Georg Brandl3ee81df2008-05-17 18:14:43 +00007164- Patch #1675423: PyComplex_AsCComplex() now tries to convert an
7165 object to complex using its __complex__() method before falling back
7166 to the __float__() method. Therefore, the functions in the cmath
7167 module now can operate on objects that define a __complex__()
7168 method.
Georg Brandl2b869942007-03-17 16:08:45 +00007169
Georg Brandl3ee81df2008-05-17 18:14:43 +00007170- Patch #1623563: allow __class__ assignment for classes with
7171 __slots__. The old and the new class are still required to have the
7172 same slot names.
Žiga Seilnacht6f2d09c2007-03-16 11:59:38 +00007173
Georg Brandl3ee81df2008-05-17 18:14:43 +00007174- Patch #1642547: Fix an error/crash when encountering syntax errors

7178 ``object.__reduce_ex__()`` is called with an object that is faking
7179 its type.
Žiga Seilnacht20f43d32007-03-15 11:44:55 +00007180
Georg Brandl3ee81df2008-05-17 18:14:43 +00007181- Patch #1680015: Don't modify __slots__ tuple if it contains an

Georg Brandl5240d742007-03-13 20:46:32 +00007184- Patch #1444529: the builtin compile() now accepts keyword arguments.
7185
Georg Brandl7b9c5552007-03-12 14:30:05 +00007186- Bug #1678647: write a newline after printing an exception in any
7187 case, even when converting the value to a string failed.
7188
Georg Brandl871f1bc2007-03-12 13:17:36 +00007189- The dir() function has been extended to call the __dir__() method on
Georg Brandl3ee81df2008-05-17 18:14:43 +00007190 its argument, if it exists. If not, it will work like before. This
7191 allows customizing the output of dir() in the presence of a
7192 __getattr__().
Georg Brandl871f1bc2007-03-12 13:17:36 +00007193
Collin Winter276887b2007-03-12 16:11:39 +00007194- Patch #922167: Python no longer segfaults when faced with infinitely
7195 self-recursive reload() calls (as reported by bug #742342).
7196
Georg Brandl3ee81df2008-05-17 18:14:43 +00007197- Patch #1675981: remove unreachable code from ``type.__new__()``
7198 method.

Georg Brandl3ee81df2008-05-17 18:14:43 +00007200- Patch #1491866: change the complex() constructor to allow
7201 parthensized forms. This means complex(repr(x)) now works instead of
7202 raising a ValueError.
Collin Wintere38051d2007-03-09 20:33:07 +00007203
Georg Brandlaa2321b2007-03-07 00:40:28 +00007204- Patch #703779: unset __file__ in __main__ after running a file. This
Georg Brandl3ee81df2008-05-17 18:14:43 +00007205 makes the filenames the warning module prints much more sensible
7206 when a PYTHONSTARTUP file is used.
Georg Brandlaa2321b2007-03-07 00:40:28 +00007207
Georg Brandl49aafc92007-03-07 00:34:46 +00007208- Variant of patch #697613: don't exit the interpreter on a SystemExit
7209 exception if the -i command line option or PYTHONINSPECT environment
Georg Brandl3ee81df2008-05-17 18:14:43 +00007210 variable is given, but break into the interactive interpreter just
7211 like on other exceptions or normal program exit.

Georg Brandl098cd692007-03-06 12:17:50 +00007218
Georg Brandl0fca97a2007-03-05 22:28:08 +00007219- Patch #1674228: when assigning a slice (old-style), check for the
7220 sq_ass_slice instead of the sq_slice slot.
7221
Georg Brandl3ee81df2008-05-17 18:14:43 +00007222- When printing an unraisable error, don't print exceptions. before
7223 the name. This duplicates the behavior whening normally printing
7224 exceptions.

Guido van Rossum8bc09652008-02-21 18:18:37 +00007366- Removed uses of dict.has_key() from distutils, and uses of

Georg Brandl3ee81df2008-05-17 18:14:43 +00007775- Patch #1530482: add pydoc.render_doc() which returns the

7790
Georg Brandl92a6bae2007-03-13 17:43:32 +00007791- Patch #1603688: ConfigParser.SafeConfigParser now checks values that
Georg Brandl3ee81df2008-05-17 18:14:43 +00007792 are set for invalid interpolation sequences that would lead to
7793 errors on reading back those values.

7847
Georg Brandl3ee81df2008-05-17 18:14:43 +00007848- unittest now verifies more of its assumptions. In particular,
7849 TestCase and TestSuite subclasses (not instances) are no longer
7850 accepted in TestSuite.addTest(). This should cause no
7851 incompatibility since it never made sense with ordinary subclasses
7852 -- the failure just occurred later, with a more cumbersome
7853 exception.

Gregory P. Smithbde4ae42008-01-17 08:35:49 +00008140 that the SMTP.starttls() caller no longer needs to call ehlo()

Georg Brandl3ee81df2008-05-17 18:14:43 +00008142 does not claim to support starttls. Adds the

Gregory P. Smithec10a4a2007-11-05 02:32:26 +00008241- pybsddb.sf.net Bug #477182: Load the database flags at database open
Georg Brandl3ee81df2008-05-17 18:14:43 +00008242 time so that opening a database previously created with the DB_DUP
8243 or DB_DUPSORT flag set will keep the proper behavior on subsequent
8244 opens. Specifically: dictionary assignment to a DB object will
8245 replace all values for a given key when the database allows
8246 duplicate values. DB users should use DB.put(k, v) when they want
8247 to store duplicates; not DB[k] = v.

8256 behavior of quoting dots if they are the second character of any

Raymond Hettingerdc1d1ba2007-11-07 02:45:46 +00008526- Add a FAST_LOOPS build option that speeds-up looping by trading away
Georg Brandl3ee81df2008-05-17 18:14:43 +00008527 periodic threadstate and signal checking in tight loops. By
8528 default, this option is turned-off. It should only be enabled in
8529 debugged, performance critical applications.

Christian Heimes5b970ad2008-02-06 13:33:44 +00008586
Georg Brandl3ee81df2008-05-17 18:14:43 +00008587- ``PySet_Add()`` can now modify a newly created frozenset. Similarly
8588 to ``PyTuple_SetItem``, it can be used to populate a brand new

8601
Georg Brandl3ee81df2008-05-17 18:14:43 +00008602- Issue #1521: On 64bit platforms, using PyArgs_ParseTuple with the t#
8603 of w# format code incorrectly truncated the length to an int, even
8604 when PY_SSIZE_T_CLEAN is set. The str.decode method used to return
8605 incorrect results with huge strings.
Georg Brandl6caad7d2008-01-26 14:19:22 +00008606

Georg Brandl3ee81df2008-05-17 18:14:43 +00008631- ``PyImport_Import`` and ``PyImport_ImportModule`` now always do
8632 absolute imports. In earlier versions they might have used relative
8633 imports under some conditions.
Christian Heimes000a0742008-01-03 22:16:32 +00008634
Georg Brandl3ee81df2008-05-17 18:14:43 +00008635- Added case insensitive comparison methods ``PyOS_stricmp(char*,
8636 char*)`` and ``PyOS_strnicmp(char*, char*, Py_ssize_t)``.
Christian Heimes000a0742008-01-03 22:16:32 +00008637
Georg Brandl3ee81df2008-05-17 18:14:43 +00008638- Bug #1542693: remove semi-colon at end of PyImport_ImportModuleEx
