Ned Deily0d0ea482012-02-10 12:59:06 +0100835- Issue #13590: On OS X 10.7 and 10.6 with Xcode 4.2, building
836 Distutils-based packages with C extension modules may fail because
837 Apple has removed gcc-4.2, the version used to build python.org
838 64-bit/32-bit Pythons. If the user does not explicitly override
839 the default C compiler by setting the CC environment variable,
840 Distutils will now attempt to compile extension modules with clang
841 if gcc-4.2 is required but not found. Also as a convenience, if
842 the user does explicitly set CC, substitute its value as the default
843 compiler in the Distutils LDSHARED configuration variable for OS X.
844 (Note, the python.org 32-bit-only Pythons use gcc-4.0 and the 10.4u
845 SDK, neither of which are available in Xcode 4. This change does not
846 attempt to override settings to support their use with Xcode 4.)

Ned Deily87e82bb2011-06-28 19:52:59 -07001119- Issue #9516: On Mac OS X, change Distutils to no longer globally attempt to
1120 check or set the MACOSX_DEPLOYMENT_TARGET environment variable for the
1121 interpreter process. This could cause failures in non-Distutils subprocesses
1122 and was unreliable since tests or user programs could modify the interpreter
1123 environment after Distutils set it. Instead, have Distutils set the the
1124 deployment target only in the environment of each build subprocess. It is
1125 still possible to globally override the default by setting
1126 MACOSX_DEPLOYMENT_TARGET before launching the interpreter; its value must be
1127 greater or equal to the default value, the value with which the interpreter
1128 was built.

1158 the ticker doesn't have to wind down to zero from the old starting point
1159 before the new interval takes effect. And if the user increases the
1160 interval, it makes sure the new limit takes effect right away rather have an

2113 This prevents user-created self-referencing ordered dictionaries from
2114 becoming permanently uncollectable GC garbage. The downside is that
2115 removing __del__ means that the internal doubly-linked list has to wait for
2116 GC collection rather than freeing memory immediately when the refcnt drops
2117 to zero.

Ezio Melottiab2eb0e2010-06-05 19:21:32 +00002576- Issue #8271: during the decoding of an invalid UTF-8 byte sequence, only the
2577 start byte and the continuation byte(s) are now considered invalid, instead
2578 of the number of bytes specified by the start byte.
2579 E.g.: '\xf1\x80AB'.decode('utf-8', 'replace') now returns u'\ufffdAB' and
2580 replaces with U+FFFD only the start byte ('\xf1') and the continuation byte
2581 ('\x80') even if '\xf1' is the start byte of a 4-bytes sequence.

2591 objects. (1) The comparison could incorrectly return True in some cases
2592 (2**53+1 == complex(2**53) == 2**53), breaking transivity of equality.

Philip Jenveyaebbaeb2010-04-06 23:24:45 +00002962- Issue #7301: Add environment variable $PYTHONWARNINGS.
2963
Benjamin Peterson3a1dfa22010-04-06 21:50:00 +00002964- Issue #8329: Don't return the same lists from select.select when no fds are
2965 changed.
2966
Georg Brandlfee0f442010-05-22 21:26:21 +00002967- Issue #8259: ``1L << (2**31)`` no longer produces an 'outrageous shift error'
Mark Dickinson82791672010-04-06 16:47:55 +00002968 on 64-bit machines. The shift count for either left or right shift is
2969 permitted to be up to sys.maxsize.

2976
Georg Brandlfee0f442010-05-22 21:26:21 +00002977- Issue #7994: Issue a PendingDeprecationWarning if object.__format__ is called
2978 with a non-empty format string. This is an effort to future-proof user
2979 code. If a derived class does not currently implement __format__ but later
2980 adds its own __format__, it would most likely break user code that had
Antoine Pitrou01a196a2011-01-02 20:05:11 +00002981 supplied a format string. This will be changed to a DeprecationWarning in
Georg Brandlfee0f442010-05-22 21:26:21 +00002982 Python 3.3 and it will be an error in Python 3.4.

Georg Brandlfee0f442010-05-22 21:26:21 +00003015- Issue #8257: The Decimal construct now accepts a float instance directly,
3016 converting that float to a Decimal of equal value:
Mark Dickinson8a950712010-04-03 15:47:46 +00003017

Georg Brandlfee0f442010-05-22 21:26:21 +00003032- Issue #7279: Comparisons involving a Decimal signaling NaN now signal
3033 InvalidOperation instead of returning False. (Comparisons involving a quiet
3034 NaN are unchanged.) Also, Decimal quiet NaNs are now hashable; Decimal
3035 signaling NaNs remain unhashable.
Mark Dickinsone096e822010-04-02 10:17:07 +00003036
Georg Brandlfee0f442010-05-22 21:26:21 +00003037- Issue #2531: Comparison operations between floats and Decimal instances now
3038 return a result based on the numeric values of the operands; previously they
3039 returned an arbitrary result based on the relative ordering of id(float) and
3040 id(Decimal).

Barry Warsawf7f2d6f2010-03-31 21:07:16 +00003042- Issue #8233: When run as a script, py_compile.py optionally takes a single
Georg Brandlfee0f442010-05-22 21:26:21 +00003043 argument `-` which tells it to read files to compile from stdin. Each line is
3044 read on demand and the named file is compiled immediately. (Original patch by

Georg Brandlfee0f442010-05-22 21:26:21 +00003054- Comparisons using one of <, <=, >, >= between a complex instance and a
3055 Fractions instance now raise TypeError instead of returning True/False. This
3056 makes Fraction <=> complex comparisons consistent with int <=> complex, float
3057 <=> complex, and complex <=> complex comparisons.

Georg Brandlba83f822010-03-14 09:50:54 +00003419- Issue #7561: Operations on empty bytearrays (such as ``int(bytearray())``)
3420 could crash in many places because of the ``PyByteArray_AS_STRING()`` macro
3421 returning NULL. The macro now returns a statically allocated empty string
3422 instead.

Georg Brandlba83f822010-03-14 09:50:54 +00003475 file position when calling `truncate()`. It would previously change the file
3476 position to the given argument, which goes against the tradition of
Antoine Pitrouf3fa0742010-01-31 22:26:04 +00003477 ftruncate() and other truncation APIs. Patch by Pascal Chambon.

3480 class used to represent files stored inside an archive. The new
3481 implementation is significantly faster and can be wrapped in a
3482 ``io.BufferedReader`` object for more speedups. It also solves an issue
3483 where interleaved calls to ``read()`` and ``readline()`` give wrong results.

Georg Brandlba83f822010-03-14 09:50:54 +00003494- Issue #7748: Since unicode values are supported for some metadata options in
3495 Distutils, the DistributionMetadata get_* methods will now return an utf-8
3496 encoded string for them. This ensures that the upload and register commands
3497 send the correct values to PyPI without any error.

Georg Brandlba83f822010-03-14 09:50:54 +00003574- The ``__complex__()`` method is now looked up on the class of instances to
3575 make it consistent with other special methods.

Antoine Pitrou5b7139a2010-01-02 21:12:58 +00003577- Issue #7462: Implement the stringlib fast search algorithm for the `rfind`,
3578 `rindex`, `rsplit` and `rpartition` methods. Patch by Florent Xicluna.
3579
Mark Dickinson1b34d252010-01-01 17:27:30 +00003580- Issue #5080: A number of functions and methods previously produced a
Georg Brandlba83f822010-03-14 09:50:54 +00003581 DeprecationWarning when passed a float argument where an integer was expected.
3582 These functions and methods now raise TypeError instead. The majority of the
3583 effects of this change are in the extension modules, but some core functions
3584 and methods are affected: notably the 'chr', 'range' and 'xrange' builtins,
3585 and many unicode/str methods.

Amaury Forgeot d'Arc8645a5c2009-12-29 22:03:38 +00003595- Issue #7413: Passing '\0' as the separator to datetime.datetime.isoformat()
3596 used to drop the time part of the result.
3597
Georg Brandlba83f822010-03-14 09:50:54 +00003598- Issue #1811: Improve accuracy and cross-platform consistency for true division
3599 of integers: the result of a/b is now correctly rounded for ints a and b (at
3600 least on IEEE 754 platforms), and in particular does not depend on the
3601 internal representation of a long.
Mark Dickinson46572832009-12-27 14:55:57 +00003602
Georg Brandlba83f822010-03-14 09:50:54 +00003603- Issue #6108: ``unicode(exception)`` and ``str(exception)`` should return the
3604 same message when only ``__str__()`` (and not ``__unicode__()``) is overridden
3605 in the subclass.
Ezio Melottif84caf42009-12-24 22:25:17 +00003606

Ronald Oussoren92919a62009-12-24 13:30:58 +00003608 executables on OSX.
3609
Georg Brandlba83f822010-03-14 09:50:54 +00003610 These executables now work properly with the arch(1) command: ``arch -ppc
3611 python`` will start a universal binary version of python in PPC mode (unlike
3612 previous releases).
Ronald Oussoren92919a62009-12-24 13:30:58 +00003613
Georg Brandlba83f822010-03-14 09:50:54 +00003614- Issue #1680159: Unicode coercion during an 'in' operation no longer masks the
3615 underlying error when the coercion fails for the left hand operand.

Antoine Pitrou80157252010-01-08 19:20:17 +00003634- Issue #7092: Remove py3k warning when importing cPickle. 2to3 handles
Georg Brandlba83f822010-03-14 09:50:54 +00003635 renaming of `cPickle` to `pickle`. The warning was annoying since there's no

Georg Brandlba83f822010-03-14 09:50:54 +00003768- Issue #7117: ``repr(x)`` for a float x returns a result based on the shortest
3769 decimal string that's guaranteed to round back to x under correct rounding
3770 (with round-half-to-even rounding mode). Previously it gave a string based on
3771 rounding x to 17 decimal digits. repr(x) for a complex number behaves
3772 similarly. On platforms where the correctly-rounded strtod and dtoa code is
3773 not supported (see below), repr is unchanged.

Georg Brandlba83f822010-03-14 09:50:54 +00003775- Issue #7117: On almost all platforms: float-to-string and string-to-float
3776 conversions within Python are now correctly rounded. Places these conversions
3777 occur include: str for floats and complex numbers; the float and complex
3778 constructors; old-style and new-style numeric formatting; serialization and
3779 deserialization of floats and complex numbers using marshal, pickle and json;
3780 parsing of float and imaginary literals in Python code; Decimal-to-float
3781 conversion.
Mark Dickinsonb678de82009-11-19 18:41:49 +00003782
Georg Brandlba83f822010-03-14 09:50:54 +00003783 The conversions use a Python-adapted version of David Gay's well-known dtoa.c,
3784 providing correctly-rounded strtod and dtoa C functions. This code is
3785 supported on Windows, and on Unix-like platforms using gcc, icc or suncc as
3786 the C compiler. There may be a small number of platforms on which correct
3787 operation of this code cannot be guaranteed, so the code is not used: notably,
3788 this applies to platforms where the C double format is not IEEE 754 binary64,
3789 and to platforms on x86 hardware where the x87 FPU is set to 64-bit precision
3790 and Python's configure script is unable to determine how to change the FPU
3791 precision. On these platforms conversions use the platform strtod and dtoa,
3792 as before.

Georg Brandlba83f822010-03-14 09:50:54 +00003794- Issue #7117: Backport round implementation from Python 3.x. ``round()`` now
3795 uses the correctly-rounded string <-> float conversions described above (when
3796 available), and so produces correctly rounded results that will display nicely
3797 under the float repr. There are two related small changes: (1) round now
3798 accepts any class with an ``__index__()`` method for its second argument (but
3799 no longer accepts floats for the second argument), and (2) an excessively
3800 large second integer argument (e.g., ``round(1.234, 10**100)``) no longer
3801 raises an exception.

Georg Brandlba83f822010-03-14 09:50:54 +00003805- Fix several issues with ``compile()``. The input can now contain Windows and

4151
Georg Brandlba83f822010-03-14 09:50:54 +00004152- Issue #4233: Changed semantic of ``_fileio.FileIO``'s ``close()`` method on

Georg Brandlba83f822010-03-14 09:50:54 +00004178- On windows, ``os.chdir()`` given unicode was not working if

4180 this code path is really executed because I cannot move to such directory on
4181 win2k)

4207 PyUnicode_DecodeUTF8() once, remember the result and output it in a second

Amaury Forgeot d'Arc05e34492008-09-10 22:04:45 +00005584- Issue #3743: In a few places, PY_FORMAT_SIZE_T was incorrectly used with
5585 PyString_FromFormat or PyErr_Format to display size_t values. The macro
5586 PY_FORMAT_SIZE_T is designed to select the correct format for the OS
5587 ``printf`` function, whereas PyString_FromFormat has an independent
5588 implementation and uses "%zd" on all platforms for size_t values.
5589 This makes a difference on win64, where ``printf`` needs "%Id" to display
5590 64bit values.

Antoine Pitrou0668c622008-08-26 22:42:08 +00005610 match Python 2.5 speed despite the __instancecheck__ / __subclasscheck__

5613 __instancecheck__ / __subclasscheck__ on the tuple rather than on each
5614 type object.

Brett Cannon1eaf0742008-09-02 01:25:16 +00005685 warnings.catch_warnings() along with some API cleanup. Expanding the tests
5686 for catch_warnings() also led to an improvement in the raising of a
5687 DeprecationWarning related to warnings.warn_explicit().
5688
Benjamin Peterson973e6c22008-09-01 23:12:58 +00005689- The deprecation warnings for the old camelCase threading API were removed.

Amaury Forgeot d'Arc293924b2008-09-02 23:19:56 +00005712- Issue #2975: When compiling several extension modules with Visual Studio 2008
5713 from the same python interpreter, some environment variables would grow
5714 without limit.
5715
Benjamin Peterson37346b22008-08-23 20:27:43 +00005716- Issue #3643: Added a few more checks to _testcapi to prevent segfaults by

Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00005753What's New in Python 2.6 beta 3?
5754================================
5755
Barry Warsaw07a4a382008-08-21 01:15:08 +00005756*Release date: 20-Aug-2008*
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00005757
5758Core and Builtins
5759-----------------
5760
Guido van Rossumf8402962008-08-20 15:01:50 +00005761- Issue #1878: Remove Py_TPFLAGS_HAVE_VERSION_TAG from
5762 Py_TPFLAGS_DEFAULT when not building the core. This means 3rd party
5763 extensions do not automatically benefit from the class attribute
5764 cache; they will have to explicitly add Py_TPFLAGS_HAVE_VERSION_TAG
5765 to their tp_flags field if they care. This is a backwards
5766 compatibility feature; in 3.0, all types will use the cache by
5767 default.
5768
Benjamin Petersonf647dc12008-08-20 01:27:30 +00005769- Keyword arguments can now follow starred arguments. (``f(a, *args,
5770 keyword=23)`` is now valid syntax.)
5771
Thomas Heller0ad5ae02008-08-19 19:25:04 +00005772- ctypes function pointers that are COM methods have a boolean True
5773 value again.
5774
Martin v. Löwisf91d46a2008-08-12 14:49:50 +00005775- Issue #3139: Make buffer-interface thread-safe wrt. PyArg_ParseTuple,
5776 by denying s# to parse objects that have a releasebuffer procedure,
5777 and introducing s*.
5778
Georg Brandl1e13ea92008-08-11 09:07:59 +00005779- Issue #3537: Fix an assertion failure when an empty but presized dict
5780 object was stored in the freelist.
5781
Mark Dickinsonb6467572008-08-04 21:30:09 +00005782- Issue #1481296: Make long(float('nan')) and int(float('nan')) raise
5783 ValueError consistently across platforms.
5784
Amaury Forgeot d'Arc39fd6722008-07-31 21:28:03 +00005785- Issue #3479: On platforms where sizeof(int) is smaller than sizeof(long)
5786 (64bit Unix, for example), unichr() would truncate its argument and return
5787 u'\x00' for unichr(2**32). Now it properly raises an OverflowError.
5788
Neal Norwitze7d8be82008-07-31 17:17:14 +00005789- Apply security patches from Apple.
5790
Amaury Forgeot d'Arc246daed2008-07-31 00:42:16 +00005791- Issue #2542: Now that issubclass() may call arbitrary code, ensure that
5792 PyErr_ExceptionMatches returns 0 when an exception occurs there.
5793
Antoine Pitrou92f82162008-07-25 22:22:08 +00005794- Issue #1819: function calls with several named parameters are now on
5795 average 35% faster (as measured by pybench).
5796
Amaury Forgeot d'Arce4921fe2008-07-21 22:00:38 +00005797- Issue #2378: An unexpected UnboundLocalError or NameError could appear when
5798 the python debugger steps into a class statement: the free variables (local
5799 variables defined in an outer scope) would be deleted from the outer scope.
5800
Gregory P. Smith0470bab2008-07-22 04:46:32 +00005801- Issue #2620: Overflow checking when allocating or reallocating memory
5802 was not always being done properly in some python types and extension
5803 modules. PyMem_MALLOC, PyMem_REALLOC, PyMem_NEW and PyMem_RESIZE have
5804 all been updated to perform better checks and places in the code that
5805 would previously leak memory on the error path when such an allocation
5806 failed have been fixed.
5807

5809-------
5810
Hirokazu Yamamoto838c79f2008-08-20 13:14:07 +00005811- Issue #3612: Added some missing basic types in ctypes.wintypes.
5812
Benjamin Petersone977ad42008-08-20 01:42:01 +00005813- The methods ``is_in_tuple()``, ``is_vararg()``, and ``is_keywordarg()`` of
5814 symtable.Symbol have been deprecated for removal in 3.0 and the next release.
5815
Amaury Forgeot d'Arc351ffb82008-08-18 19:23:47 +00005816- Issue #2234: distutils failed for some versions of the cygwin compiler. The
5817 version reported by these tools does not necessarily follow the python
5818 version numbering scheme, so the module is less strict when parsing it.
5819
Nick Coghlanf70385a2008-08-18 12:42:46 +00005820- Issue #2235: Added Py3k warnings for types which will become unhashable
5821 under the stricter __hash__ inheritance rules in 3.0. Several types
5822 which did not meet the rules for hash invariants and were already
5823 unhashable in 3.0 have now been explicitly flagged as unhashable in
5824 2.6 as well (collections.Mapping, collections.Set, unittest.TestSuite,
5825 xml.dom.minidom.NamedNodeMap, numbers.Number, UserList.UserList)
5826
Brett Cannon88f801d2008-08-18 00:46:22 +00005827- Update __all__ for cookielib, csv, os, urllib2, and weakref to include things
5828 imported into the module but exposed as part of the module's API.
5829
Brett Cannon7b96f072008-08-18 00:41:11 +00005830- Remove an unneeded import of abc.ABCMeta from 'inspect'.
5831
Brett Cannon46225e72008-08-18 00:36:52 +00005832- Remove unneeded imports of 'sys' and 'warnings' from 'io'.

Brett Cannon25c9d6a2008-08-17 22:10:11 +00005834- Remove unneeded imports of 'warnings' from shelve, filecmp, and dummy_thread.
5835
Hirokazu Yamamoto41a81eb2008-08-17 13:10:46 +00005836- Issue #3575: Incremental decoder's decode function now takes bytearray
5837 by using 's*' instead of 't#'.
5838
Mark Dickinson3e4caeb2009-02-21 20:27:01 +00005839- Issue #2222: Fixed reference leak when occurred os.rename()
Hirokazu Yamamoto7f30a682008-08-17 09:46:56 +00005840 fails unicode conversion on 2nd parameter. (windows only)
5841
Georg Brandl222e2082010-08-01 22:27:39 +00005842- Issue #2464: urllib2 now supports a malformation in the URL received
Facundo Batista94f243a2008-08-17 03:38:39 +00005843 in a redirect.
5844
Brett Cannonabe423e2008-08-16 21:47:07 +00005845- Silence the DeprecationWarning raised when importing mimetools in
Brett Cannon721b1452008-08-16 22:00:27 +00005846 BaseHTTPServer, cgi (and rfc822), httplib.
Brett Cannonabe423e2008-08-16 21:47:07 +00005847
Facundo Batistaeb90b782008-08-16 14:44:07 +00005848- Issue #2776: fixed small issue when handling an URL with double slash
5849 after a 302 response in the case of not going through a proxy.
5850
Antoine Pitroub90a8be2008-08-15 21:03:21 +00005851- Issue #2676: in the email package, content-type parsing was hanging on
5852 pathological input because of quadratic or exponential behaviour of a
5853 regular expression.
5854
Antoine Pitrou11ec65d2008-08-14 21:04:30 +00005855- Issue #3476: binary buffered reading through the new "io" library is now
5856 thread-safe.
5857
Brett Cannonbf3157b2008-08-14 05:00:03 +00005858- Silence the DeprecationWarning of rfc822 when it is imported by mimetools
5859 since mimetools itself is deprecated. Because modules are cached, all
5860 subsequent imports of rfc822 will not raise a visible DeprecationWarning.
5861
Antoine Pitrou9fcd4b32008-08-11 17:21:36 +00005862- Issue #3134: shutil referenced undefined WindowsError symbol.
5863
Robert Schuppenies14646332008-08-10 11:01:53 +00005864- Issue #1342811: Fix leak in Tkinter.Menu.delete. Commands associated to
5865 menu entries were not deleted.
5866
Brett Cannon83e81842008-08-09 23:30:55 +00005867- Copied the implementation of reduce() to _functools.reduce() to have a
5868 version that did not raise a DeprecationWarning under -3.
5869
Antoine Pitrou76b8bee2008-08-09 17:27:23 +00005870- Issue #3205: When iterating over a BZ2File fails allocating memory, raise
5871 a MemoryError rather than silently stop the iteration.
5872
Guido van Rossum59ce9012008-08-09 14:55:34 +00005873- Issue #3487: sre "bytecode" validator. Passing invalid "re-bytecode"
5874 to _sre.compile() will now be rejected. This should not affect anybody
5875 since the re.compile() function never generates invalid re-bytecode.
5876
Skip Montanaroa032bf42008-08-08 22:52:51 +00005877- Issue #3436: Make csv.DictReader's fieldnames attribute a property so that
5878 upon first access it can be automatically initialized from the csv file if
5879 it wasn't initialized during instantiation.
5880
Brett Cannon3aa2a492008-08-06 22:28:09 +00005881- Issue #2338: Create imp.reload() to help with transitioning to Python 3.0 as
5882 the reload() built-in has been removed.
5883
Brett Cannon7e30b672008-08-04 21:52:25 +00005884- Changed code in the following modules/packages to remove warnings raised
Brett Cannonc1b76e42008-08-09 23:06:16 +00005885 while running under the ``-3`` flag: aifc, asynchat, asyncore, bdb, bsddb,

Antoine Pitroude781a42008-08-09 12:43:23 +00005896 asking for a specific length. This problem only affected files opened
5897 using the new "io" module, not the built-in open() function.
Benjamin Peterson01a24322008-07-28 23:35:27 +00005898

5923 file name rather than a ZipInfo instance, so files are extracted with
5924 mode 0600 rather than 000 under Unix.
5925

5943 regarding lack of coverage of new-style classes have also been
5944 removed, since the coverage is now fairly reasonable.

Mark Dickinson64b7e502008-07-16 09:40:03 +00005959- Issue #3360: Fix incorrect parsing of '020000000000.0', which
5960 produced a ValueError instead of giving the correct float.
5961
Eric Smitha5fa5a22008-07-16 00:11:49 +00005962- Issue #3083: Add alternate (#) formatting for bin, oct, hex output
5963 for str.format(). This adds the prefix 0b, 0o, or 0x, respectively.
5964
Mark Dickinson7103aa42008-07-15 19:08:33 +00005965- Issue #3008: the float type has a new instance method 'float.hex'
5966 and a new class method 'float.fromhex' to convert floating-point
5967 numbers to and from hexadecimal strings, respectively.
5968
Nick Coghlan6d6bd442008-07-15 15:40:22 +00005969- Issue #2235: __hash__ is once again inherited by default. To allow
5970 collections.Hashable to remain meaningful in the presence of the
5971 default hash implementation (object.__hash__), it is now possible
5972 to explicit block inheritance of hash by setting __hash__=None at
5973 the Python level, or tp_hash=PyObject_HashNotImplemented at the C
5974 level.
5975
Nick Coghlanb028f502008-07-13 14:52:36 +00005976- Issue #3221: Issue a RuntimeWarning instead of raising SystemError if
5977 the parent module cannot be found while performing an absolute import.
5978 This means that an incorrectly defined __package__ attribute will
5979 now only prevent relative imports in that module rather than causing
5980 all imports from that module to fail.
5981
Nick Coghlan14ff9942008-07-08 14:21:42 +00005982- Issue #2517: Allow unicode messages in Exceptions again by correctly

5993
Mark Dickinson1ec2fcd2008-06-20 14:53:43 +00005994- Issue #3004: Minor change to slice.indices(): the start and stop
5995 arguments are now treated identically, making the behaviour easier
5996 to describe and understand. For example, slice(None, -10,
5997 1).indices(9) now returns (0, 0, 1) instead of (0, -1, 1), and
5998 slice(None, 10, -1).indices(10) returns (9, 9, -1) instead of (9,
5999 10, -1).

6042 both unnecessary (HTTP allows text content to be sent in several forms) and

Georg Brandl3ee81df2008-05-17 18:14:43 +00006515- Issue #1631171: Re-implement the 'warnings' module in C (the
6516 original Python code has been kept as backup). This will allow for
6517 using the 'warning's machinery in such places as the parser where
6518 use of pure Python code is not possible. Both the ``showarning()``
6519 and ``formatwarning()`` gain an optional 'line' argument which is
6520 not called by default for backwards-compatibility reasons. Setting
6521 ``warnings.showwarning()`` to an implementation that lacks support
6522 for the ``line`` argument will raise a DeprecationWarning.

Georg Brandl3ee81df2008-05-17 18:14:43 +00006585- Issue #2550: The approach used by client/server code for obtaining
6586 ports to listen on in network-oriented tests has been refined in an
6587 effort to facilitate running multiple instances of the entire
6588 regression test suite in parallel without issue.
6589 test_support.bind_port() has been fixed such that it will always
6590 return a unique port -- which wasn't always the case with the
6591 previous implementation, especially if socket options had been set
6592 that affected address reuse (i.e. SO_REUSEADDR, SO_REUSEPORT). The
6593 new implementation of bind_port() will actually raise an exception
6594 if it is passed an AF_INET/SOCK_STREAM socket with either the
6595 SO_REUSEADDR or SO_REUSEPORT socket option set. Furthermore, if
6596 available, bind_port() will set the SO_EXCLUSIVEADDRUSE option on
6597 the socket it's been passed. This currently only applies to
6598 Windows. This option prevents any other sockets from binding to the
6599 host/port we've bound to, thus removing the possibility of the
6600 'non-deterministic' behaviour, as Microsoft puts it, that occurs
6601 when a second SOCK_STREAM socket binds and accepts to a host/port
6602 that's already been bound by another socket. The optional preferred
6603 port parameter to bind_port() has been removed. Under no
6604 circumstances should tests be hard coding ports!
6605
6606 test_support.find_unused_port() has also been introduced, which will
6607 pass a temporary socket object to bind_port() in order to obtain an
6608 unused port. The temporary socket object is then closed and
6609 deleted, and the port is returned. This method should only be used
6610 for obtaining an unused port in order to pass to an external program
6611 (i.e. the -accept [port] argument to openssl's s_server mode) or as
6612 a parameter to a server-oriented class that doesn't give you direct
6613 access to the underlying socket used.
6614
6615 Finally, test_support.HOST has been introduced, which should be used
6616 for the host argument of any relevant socket calls (i.e. bind and
6617 connect).
Trent Nelsone41b0062008-04-08 23:47:30 +00006618
6619 The following tests were updated to following the new conventions:
Georg Brandl3ee81df2008-05-17 18:14:43 +00006620 test_socket, test_smtplib, test_asyncore, test_ssl, test_httplib,
Trent Nelsone41b0062008-04-08 23:47:30 +00006621 test_poplib, test_ftplib, test_telnetlib, test_socketserver,
6622 test_asynchat and test_socket_ssl.
6623
Georg Brandl3ee81df2008-05-17 18:14:43 +00006624 It is now possible for multiple instances of the regression test
6625 suite to run in parallel without issue.

Facundo Batistafc2d0102008-02-23 12:01:13 +00006903
Eric Smitha73fbe72008-02-23 03:09:44 +00006904- Added the future_builtins module, which contains hex() and oct().
6905 These are the PEP 3127 version of these functions, designed to be
6906 compatible with the hex() and oct() builtins from Python 3.0. They
6907 differ slightly in their output formats from the existing, unchanged
6908 Python 2.6 builtins. The expected usage of the future_builtins
6909 module is:
6910 from future_builtins import hex, oct
6911
Eric Smith7ef40bf2008-02-20 23:34:22 +00006912- Issue #1600: Modifed PyOS_ascii_formatd to use at most 2 digit
6913 exponents for exponents with absolute value < 100. Follows C99
6914 standard. This is a change on Windows, which would use 3 digits.
6915 Also, added 'n' to the formats that PyOS_ascii_formatd understands,
6916 so that any alterations it does to the resulting string will be
6917 available in stringlib/formatter.h (for float.__format__).
6918
Eric Smith5a3c1352008-02-19 13:21:56 +00006919- Implemented PEP 3101, Advanced String Formatting. This adds a new
6920 builtin format(); a format() method for str and unicode; a
6921 __format__() method to object, str, unicode, int, long, float, and
6922 datetime; the class string.Formatter; and the C API
6923 PyObject_Format().
6924
Georg Brandl3ee81df2008-05-17 18:14:43 +00006925- Fixed several potential crashes, all caused by specially crafted
6926 __del__ methods exploiting objects in temporarily inconsistent
6927 state.
Amaury Forgeot d'Arc632fad32008-02-16 20:55:24 +00006928
Vinay Sajipb7edfc42008-04-02 21:10:23 +00006929- Issue #2115: Important speedup in setting __slot__ attributes. Also
Georg Brandl3ee81df2008-05-17 18:14:43 +00006930 prevent a possible crash: an Abstract Base Class would try to access
6931 a slot on a registered virtual subclass.
Amaury Forgeot d'Arc60d6c7f2008-02-15 21:22:45 +00006932

Georg Brandl3ee81df2008-05-17 18:14:43 +00006936- Clear all free lists during a gc.collect() of the highest generation
6937 in order to allow pymalloc to free more arenas. Python may give back
6938 memory to the OS earlier.
Christian Heimes3b718a72008-02-14 12:47:33 +00006939
Georg Brandl3ee81df2008-05-17 18:14:43 +00006940- Issue #2045: Fix an infinite recursion triggered when printing a
6941 subclass of collections.defaultdict, if its default_factory is set
6942 to a bound method.
Amaury Forgeot d'Arcb01aa432008-02-08 00:56:02 +00006943
Christian Heimesf75dbef2008-02-08 00:11:31 +00006944- Fixed a minor memory leak in dictobject.c. The content of the free
6945 list was not freed on interpreter shutdown.
6946
Georg Brandl21e99f42010-03-07 15:23:59 +00006947- Limit free list of method and built-in function objects to 256
Georg Brandl3ee81df2008-05-17 18:14:43 +00006948 entries each.
Christian Heimes6075a822008-02-06 12:44:34 +00006949
Georg Brandl3ee81df2008-05-17 18:14:43 +00006950- Patch #1953: Added ``sys._compact_freelists()`` and the C API
6951 functions ``PyInt_CompactFreeList`` and ``PyFloat_CompactFreeList``
Christian Heimes422051a2008-02-04 18:00:12 +00006952 to compact the internal free lists of pre-allocted ints and floats.
6953
Georg Brandl3ee81df2008-05-17 18:14:43 +00006954- Issue #1983: Fixed return type of fork(), fork1() and forkpty()
6955 calls. Python expected the return type int but the fork familie
6956 returns pi_t.
Christian Heimes951cc0f2008-01-31 23:08:23 +00006957
Georg Brandl3ee81df2008-05-17 18:14:43 +00006958- Issue #1678380: Fix a bug that identifies 0j and -0j when they
6959 appear in the same code unit.

6968 the internal lookup cache for ref leak tests.
Christian Heimes908caac2008-01-27 23:34:59 +00006969
Georg Brandl3ee81df2008-05-17 18:14:43 +00006970- Patch #1473257: generator objects gain a gi_code attribute. This is
6971 the same object as the func_code attribute of the function that
6972 produced the generator.
Georg Brandl0cdf9a32008-01-26 14:14:20 +00006973
Georg Brandl3ee81df2008-05-17 18:14:43 +00006974- Issue #1920: "while 0" statements were completely removed by the
6975 compiler, even in the presence of an "else" clause, which is
6976 supposed to be run when the condition is false. Now the compiler
6977 correctly emits bytecode for the "else" suite.
Amaury Forgeot d'Arc31eaafe2008-01-24 22:59:25 +00006978
Guido van Rossumeead05f2008-01-24 18:21:02 +00006979- A few crashers fixed: weakref_in_del.py (issue #1377858);
6980 loosing_dict_ref.py (issue #1303614, test67.py);
6981 borrowed_ref_[34].py (not in tracker).
6982
Vinay Sajipd7cf32e2008-01-24 12:43:33 +00006983- Issue #1069410: The "can't load dll" message box on Windows is
Christian Heimesb2302ba2008-01-23 17:15:06 +00006984 suppressed while an extension is loaded by calling SetErrorMode in
6985 dynload_win.c. The error is still reported properly.
6986
Georg Brandl3ee81df2008-05-17 18:14:43 +00006987- Issue #1915: Python compiles with --enable-unicode=no again. However
Christian Heimes082c9b02008-01-23 14:20:50 +00006988 several extension methods and modules do not work without unicode
6989 support.
6990
Georg Brandl26543b12008-01-21 18:36:51 +00006991- Issue #1882: when compiling code from a string, encoding cookies in the
6992 second line of code were not always recognized correctly.
6993
Georg Brandl14404b62008-01-19 19:27:05 +00006994- Issue #1679: "0x" was taken as a valid integer literal.
6995
Georg Brandl6caad7d2008-01-26 14:19:22 +00006996- Issue #1865: ``bytes`` as an alias for ``str`` and b"" as an alias "" were
Christian Heimes288e89a2008-01-18 18:24:07 +00006997 added.
6998
Christian Heimesc94e2b52008-01-14 04:13:37 +00006999- sys.float_info / PyFloat_GetInfo: The floating point information
7000 object was converted from a dict to a specialized structseq object.
7001
Georg Brandl3ee81df2008-05-17 18:14:43 +00007002- Patch #1816: Added sys.flags structseq. It exposes the status of
7003 most command line arguments and PYTHON* environment variables.
Christian Heimesf31b69f2008-01-14 03:42:48 +00007004
Georg Brandl3ee81df2008-05-17 18:14:43 +00007005- Objects/structseq.c: Implemented new structseq representation. The
7006 patch makes structseqs (e.g. the return value of os.stat) more
7007 readable.
Christian Heimes9c201962008-01-14 03:33:52 +00007008
Georg Brandl3ee81df2008-05-17 18:14:43 +00007009- Patch #1700288: added a type attribute cache that caches method

7018 envvar and sys.dont_write_bytecode attribute. All these can be set
7019 to forbid Python to attempt to write compiled bytecode files.
Georg Brandl2da0fce2008-01-07 17:09:35 +00007020
Georg Brandl3ee81df2008-05-17 18:14:43 +00007021- Improve some exception messages when Windows fails to load an
7022 extension module. Now we get for example '%1 is not a valid Win32
7023 application' instead of 'error code 193'.

Christian Heimes0a8143f2007-12-18 23:22:54 +00007030- Issue #1635: Platform independent creation and representation of NaN
Georg Brandl3ee81df2008-05-17 18:14:43 +00007031 and INF. float("nan"), float("inf") and float("-inf") now work on
7032 every platform with IEEE 754 semantics.

Georg Brandl3ee81df2008-05-17 18:14:43 +00007034- Compiler now generates simpler and faster code for dictionary
7035 literals. The oparg for BUILD_MAP now indicates an estimated
7036 dictionary size. There is a new opcode, STORE_MAP, for adding
7037 entries to the dictionary.

7067 file can now be directly executed by passing their name to the
7068 interpreter. The directory/zipfile is automatically inserted as the
7069 first entry in sys.path.

Georg Brandl3ee81df2008-05-17 18:14:43 +00007071- Issue #1265: Fix a problem with sys.settrace, if the tracing
7072 function uses a generator expression when at the same time the
7073 executed code is closing a paused generator.
Amaury Forgeot d'Arc0d75f092007-11-13 21:54:28 +00007074

7080
Georg Brandl21e99f42010-03-07 15:23:59 +00007081- The enumerate() built-in function is no longer bounded to sequences
Georg Brandl3ee81df2008-05-17 18:14:43 +00007082 smaller than LONG_MAX. Formerly, it raised an OverflowError. Now,
7083 automatically shifts from ints to longs.
Raymond Hettinger8f669372007-10-03 21:18:11 +00007084
Georg Brandl3ee81df2008-05-17 18:14:43 +00007085- Issue #1686386: Tuple's tp_repr did not take into account the
7086 possibility of having a self-referential tuple, which is possible
7087 from C code. Nor did object's tp_str consider that a type's tp_str
7088 could do something that could lead to an inifinite recursion.
7089 Py_ReprEnter() and Py_EnterRecursiveCall(), respectively, fixed the
7090 issues.
Brett Cannon0b14f242007-09-30 19:45:10 +00007091
Georg Brandl3ee81df2008-05-17 18:14:43 +00007092- Issue #1164: It was possible to trigger deadlock when using the
7093 'print' statement to write to a file since the GIL was not released
7094 as needed. Now PyObject_Print() does the right thing along with
7095 various tp_print implementations of the built-in types and those in
7096 the collections module.
Brett Cannon01531592007-09-17 03:28:34 +00007097
Georg Brandl3ee81df2008-05-17 18:14:43 +00007098- Issue #1147: Exceptions were directly allowing string exceptions in
7099 their throw() method even though string exceptions no longer
7100 allowed.

Georg Brandl3ee81df2008-05-17 18:14:43 +00007102- Issue #1096: Prevent a segfault from getting the repr of a very
7103 deeply nested list by using the recursion counter.
Brett Cannona0c05512007-09-10 21:38:27 +00007104
Brett Cannon1e534b52007-09-07 04:18:30 +00007105- Issue #1202533: Fix infinite recursion calls triggered by calls to
Georg Brandl3ee81df2008-05-17 18:14:43 +00007106 PyObject_Call() never calling back out to Python code to trigger
7107 recursion depth updates/checks. Required the creation of a static
7108 RuntimeError instance in case normalizing an exception put the
7109 recursion check value past its limit. Fixes crashers
7110 infinite_rec_(1|2|4|5).py.
Brett Cannon1e534b52007-09-07 04:18:30 +00007111

Neal Norwitz0ac60192007-05-27 04:08:54 +00007125- Add new attribute names for function objects. All the func_* become
Georg Brandl3ee81df2008-05-17 18:14:43 +00007126 __*__ attributes. (Some already existed, e.g., __doc__ and
7127 __name__.)
Neal Norwitz0ac60192007-05-27 04:08:54 +00007128
Neal Norwitz8b2bfbc2007-05-23 06:35:32 +00007129- Add -3 option to the interpreter to warn about features that are
7130 deprecated and will be changed/removed in Python 3.0.
7131
Georg Brandl2134e752007-05-21 20:34:16 +00007132- Patch #1686487: you can now pass any mapping after '**' in function
7133 calls.
7134
Collin Winter62903052007-05-18 23:11:24 +00007135- except clauses may now be spelled either "except E, target:" or
Georg Brandl3ee81df2008-05-17 18:14:43 +00007136 "except E as target:". This is to provide forwards compatibility
7137 with Python 3.0.
Collin Winter62903052007-05-18 23:11:24 +00007138
Brett Cannon229cee22007-05-05 01:34:02 +00007139- Deprecate BaseException.message as per PEP 352.
7140
Georg Brandl3ee81df2008-05-17 18:14:43 +00007141- Issue #1303614: don't expose object's __dict__ when the dict is
Georg Brandl21e99f42010-03-07 15:23:59 +00007142 inherited from a built-in base.
Armin Rigo9790a272007-05-02 19:23:31 +00007143
Vinay Sajip8549ce32007-05-06 17:53:37 +00007144- When __slots__ are set to a unicode string, make it work the same as
Neal Norwitzcbd9ee62007-04-14 05:25:50 +00007145 setting a plain string, ie don't expand to single letter identifiers.
7146
Raymond Hettinger13936692007-04-11 18:40:58 +00007147- Request #1191699: Slices can now be pickled.
7148
Raymond Hettinger4db5fe92007-04-12 04:10:00 +00007149- Request #1193128: str.translate() now allows a None argument for
7150 translations that only remove characters without re-mapping the
7151 remaining characters.
7152
Georg Brandl5cb76c12007-03-21 09:00:39 +00007153- Patch #1682205: a TypeError while unpacking an iterable is no longer

7157
Guido van Rossum143b5642007-03-23 04:58:42 +00007158- Bug #1683368: The object.__init__() and object.__new__() methods are
7159 now stricter in rejecting excess arguments. The only time when
7160 either allows excess arguments is when it is not overridden and the
7161 other one is. For backwards compatibility, when both are
7162 overridden, it is a deprecation warning (for now; maybe a Py3k
Guido van Rossum234b1ff2007-03-23 19:39:01 +00007163 warning later). Also, type.__init__() insists on the same signature
7164 as supported by type.__new__().
Guido van Rossum143b5642007-03-23 04:58:42 +00007165
Georg Brandl3ee81df2008-05-17 18:14:43 +00007166- Patch #1675423: PyComplex_AsCComplex() now tries to convert an
7167 object to complex using its __complex__() method before falling back
7168 to the __float__() method. Therefore, the functions in the cmath
7169 module now can operate on objects that define a __complex__()
7170 method.
Georg Brandl2b869942007-03-17 16:08:45 +00007171
Georg Brandl3ee81df2008-05-17 18:14:43 +00007172- Patch #1623563: allow __class__ assignment for classes with
7173 __slots__. The old and the new class are still required to have the
7174 same slot names.

7180 ``object.__reduce_ex__()`` is called with an object that is faking
7181 its type.

7187
Georg Brandl7b9c5552007-03-12 14:30:05 +00007188- Bug #1678647: write a newline after printing an exception in any
7189 case, even when converting the value to a string failed.
7190
Georg Brandl871f1bc2007-03-12 13:17:36 +00007191- The dir() function has been extended to call the __dir__() method on
Georg Brandl3ee81df2008-05-17 18:14:43 +00007192 its argument, if it exists. If not, it will work like before. This
7193 allows customizing the output of dir() in the presence of a
7194 __getattr__().
Georg Brandl871f1bc2007-03-12 13:17:36 +00007195
Collin Winter276887b2007-03-12 16:11:39 +00007196- Patch #922167: Python no longer segfaults when faced with infinitely
7197 self-recursive reload() calls (as reported by bug #742342).
7198
Georg Brandl3ee81df2008-05-17 18:14:43 +00007199- Patch #1675981: remove unreachable code from ``type.__new__()``

Georg Brandl3ee81df2008-05-17 18:14:43 +00007202- Patch #1491866: change the complex() constructor to allow
7203 parthensized forms. This means complex(repr(x)) now works instead of
7204 raising a ValueError.
Collin Wintere38051d2007-03-09 20:33:07 +00007205
Georg Brandlaa2321b2007-03-07 00:40:28 +00007206- Patch #703779: unset __file__ in __main__ after running a file. This
Georg Brandl3ee81df2008-05-17 18:14:43 +00007207 makes the filenames the warning module prints much more sensible
7208 when a PYTHONSTARTUP file is used.
Georg Brandlaa2321b2007-03-07 00:40:28 +00007209

Georg Brandl0fca97a2007-03-05 22:28:08 +00007221- Patch #1674228: when assigning a slice (old-style), check for the
7222 sq_ass_slice instead of the sq_slice slot.
7223
Georg Brandl3ee81df2008-05-17 18:14:43 +00007224- When printing an unraisable error, don't print exceptions. before
7225 the name. This duplicates the behavior whening normally printing
7226 exceptions.

Georg Brandl3ee81df2008-05-17 18:14:43 +00007759 AttributeError instead of an IOError when the server's response

Georg Brandl3ee81df2008-05-17 18:14:43 +00007777- Patch #1530482: add pydoc.render_doc() which returns the

7792
Georg Brandl92a6bae2007-03-13 17:43:32 +00007793- Patch #1603688: ConfigParser.SafeConfigParser now checks values that
Georg Brandl3ee81df2008-05-17 18:14:43 +00007794 are set for invalid interpolation sequences that would lead to
7795 errors on reading back those values.

7849
Georg Brandl3ee81df2008-05-17 18:14:43 +00007850- unittest now verifies more of its assumptions. In particular,
7851 TestCase and TestSuite subclasses (not instances) are no longer
7852 accepted in TestSuite.addTest(). This should cause no
7853 incompatibility since it never made sense with ordinary subclasses
7854 -- the failure just occurred later, with a more cumbersome
7855 exception.

Gregory P. Smithbde4ae42008-01-17 08:35:49 +00008142 that the SMTP.starttls() caller no longer needs to call ehlo()

Gregory P. Smithec10a4a2007-11-05 02:32:26 +00008243- pybsddb.sf.net Bug #477182: Load the database flags at database open
Georg Brandl3ee81df2008-05-17 18:14:43 +00008244 time so that opening a database previously created with the DB_DUP
8245 or DB_DUPSORT flag set will keep the proper behavior on subsequent
8246 opens. Specifically: dictionary assignment to a DB object will
8247 replace all values for a given key when the database allows
8248 duplicate values. DB users should use DB.put(k, v) when they want
8249 to store duplicates; not DB[k] = v.

Georg Brandl3ee81df2008-05-17 18:14:43 +00008529 periodic threadstate and signal checking in tight loops. By
8530 default, this option is turned-off. It should only be enabled in

Christian Heimes5b970ad2008-02-06 13:33:44 +00008588
Georg Brandl3ee81df2008-05-17 18:14:43 +00008589- ``PySet_Add()`` can now modify a newly created frozenset. Similarly
8590 to ``PyTuple_SetItem``, it can be used to populate a brand new

8603
Georg Brandl3ee81df2008-05-17 18:14:43 +00008604- Issue #1521: On 64bit platforms, using PyArgs_ParseTuple with the t#
8605 of w# format code incorrectly truncated the length to an int, even
8606 when PY_SSIZE_T_CLEAN is set. The str.decode method used to return
8607 incorrect results with huge strings.
Georg Brandl6caad7d2008-01-26 14:19:22 +00008608
Georg Brandl3ee81df2008-05-17 18:14:43 +00008609- Issue #1629: Renamed Py_Size, Py_Type and Py_Refcnt to Py_SIZE,

8631 outside of pystate.c and should not be necessary.
8632
Georg Brandl3ee81df2008-05-17 18:14:43 +00008633- ``PyImport_Import`` and ``PyImport_ImportModule`` now always do
8634 absolute imports. In earlier versions they might have used relative
8635 imports under some conditions.
Christian Heimes000a0742008-01-03 22:16:32 +00008636
Georg Brandl3ee81df2008-05-17 18:14:43 +00008637- Added case insensitive comparison methods ``PyOS_stricmp(char*,
8638 char*)`` and ``PyOS_strnicmp(char*, char*, Py_ssize_t)``.
Christian Heimes000a0742008-01-03 22:16:32 +00008639
Georg Brandl3ee81df2008-05-17 18:14:43 +00008640- Bug #1542693: remove semi-colon at end of PyImport_ImportModuleEx

Georg Brandl3ee81df2008-05-17 18:14:43 +00008665- Removed the macfs module. It had been deprecated since Python 2.5.
8666 This lead to the deprecation of macostools.touched() as it relied
8667 solely on macfs and was a no-op under OS X.
