Ned Deily0d0ea482012-02-10 12:59:06 +0100850- Issue #13590: On OS X 10.7 and 10.6 with Xcode 4.2, building
851 Distutils-based packages with C extension modules may fail because
852 Apple has removed gcc-4.2, the version used to build python.org
853 64-bit/32-bit Pythons. If the user does not explicitly override
854 the default C compiler by setting the CC environment variable,
855 Distutils will now attempt to compile extension modules with clang
856 if gcc-4.2 is required but not found. Also as a convenience, if
857 the user does explicitly set CC, substitute its value as the default
858 compiler in the Distutils LDSHARED configuration variable for OS X.
859 (Note, the python.org 32-bit-only Pythons use gcc-4.0 and the 10.4u
860 SDK, neither of which are available in Xcode 4. This change does not
861 attempt to override settings to support their use with Xcode 4.)

1133
Ned Deily87e82bb2011-06-28 19:52:59 -07001134- Issue #9516: On Mac OS X, change Distutils to no longer globally attempt to
1135 check or set the MACOSX_DEPLOYMENT_TARGET environment variable for the
1136 interpreter process. This could cause failures in non-Distutils subprocesses
1137 and was unreliable since tests or user programs could modify the interpreter
1138 environment after Distutils set it. Instead, have Distutils set the the
1139 deployment target only in the environment of each build subprocess. It is
1140 still possible to globally override the default by setting
1141 MACOSX_DEPLOYMENT_TARGET before launching the interpreter; its value must be
1142 greater or equal to the default value, the value with which the interpreter
1143 was built.

Barry Warsawc5643282011-07-19 17:06:30 -04001171- sys.setcheckinterval() now updates the current ticker count as well as
1172 updating the check interval, so if the user decreases the check interval,
1173 the ticker doesn't have to wind down to zero from the old starting point
1174 before the new interval takes effect. And if the user increases the
1175 interval, it makes sure the new limit takes effect right away rather have an
1176 early task switch before recognizing the new interval.

2128 This prevents user-created self-referencing ordered dictionaries from
2129 becoming permanently uncollectable GC garbage. The downside is that
2130 removing __del__ means that the internal doubly-linked list has to wait for
2131 GC collection rather than freeing memory immediately when the refcnt drops
2132 to zero.
2133

R. David Murray7c4bf552010-08-25 01:45:57 +00002163- Issue #1194222: email.utils.parsedate now returns RFC2822 compliant four
2164 character years even if the message contains RFC822 two character years.

2201 patch by Jason V. Miller.

2980 changed.

Georg Brandlfee0f442010-05-22 21:26:21 +00002992- Issue #7994: Issue a PendingDeprecationWarning if object.__format__ is called
2993 with a non-empty format string. This is an effort to future-proof user
2994 code. If a derived class does not currently implement __format__ but later
2995 adds its own __format__, it would most likely break user code that had
Antoine Pitrou01a196a2011-01-02 20:05:11 +00002996 supplied a format string. This will be changed to a DeprecationWarning in
Georg Brandlfee0f442010-05-22 21:26:21 +00002997 Python 3.3 and it will be an error in Python 3.4.

Georg Brandlfee0f442010-05-22 21:26:21 +00003047- Issue #7279: Comparisons involving a Decimal signaling NaN now signal
3048 InvalidOperation instead of returning False. (Comparisons involving a quiet
3049 NaN are unchanged.) Also, Decimal quiet NaNs are now hashable; Decimal
3050 signaling NaNs remain unhashable.
Mark Dickinsone096e822010-04-02 10:17:07 +00003051
Georg Brandlfee0f442010-05-22 21:26:21 +00003052- Issue #2531: Comparison operations between floats and Decimal instances now
3053 return a result based on the numeric values of the operands; previously they
3054 returned an arbitrary result based on the relative ordering of id(float) and
3055 id(Decimal).

Georg Brandlfee0f442010-05-22 21:26:21 +00003069- Comparisons using one of <, <=, >, >= between a complex instance and a
3070 Fractions instance now raise TypeError instead of returning True/False. This
3071 makes Fraction <=> complex comparisons consistent with int <=> complex, float
3072 <=> complex, and complex <=> complex comparisons.

3430 and add the additional members returned in an OSVERSIONINFOEX structure. The
3431 new members are service_pack_major, service_pack_minor, suite_mask, and

Georg Brandlba83f822010-03-14 09:50:54 +00003434- Issue #7561: Operations on empty bytearrays (such as ``int(bytearray())``)
3435 could crash in many places because of the ``PyByteArray_AS_STRING()`` macro
3436 returning NULL. The macro now returns a statically allocated empty string
3437 instead.

3447 strings,
3448 (2) a crash in dtoa.c that occurred in debug builds when parsing certain long
3449 numeric strings corresponding to subnormal values,

Antoine Pitroud840e512010-02-04 20:20:18 +00003482- Issue #4772: Raise a ValueError when an unknown Bluetooth protocol is
Georg Brandlba83f822010-03-14 09:50:54 +00003483 specified, rather than fall through to AF_PACKET (in the ``socket`` module).

Antoine Pitrouf3fa0742010-01-31 22:26:04 +00003489- Issue #6939: Fix file I/O objects in the `io` module to keep the original
Georg Brandlba83f822010-03-14 09:50:54 +00003490 file position when calling `truncate()`. It would previously change the file
3491 position to the given argument, which goes against the tradition of
Antoine Pitrouf3fa0742010-01-31 22:26:04 +00003492 ftruncate() and other truncation APIs. Patch by Pascal Chambon.
3493
Georg Brandlba83f822010-03-14 09:50:54 +00003494- Issue #7610: Reworked implementation of the internal ``zipfile.ZipExtFile``
3495 class used to represent files stored inside an archive. The new
3496 implementation is significantly faster and can be wrapped in a
3497 ``io.BufferedReader`` object for more speedups. It also solves an issue
3498 where interleaved calls to ``read()`` and ``readline()`` give wrong results.

Georg Brandlba83f822010-03-14 09:50:54 +00003509- Issue #7748: Since unicode values are supported for some metadata options in
3510 Distutils, the DistributionMetadata get_* methods will now return an utf-8
3511 encoded string for them. This ensures that the upload and register commands
3512 send the correct values to PyPI without any error.

3587-----------------
3588
Georg Brandlba83f822010-03-14 09:50:54 +00003589- The ``__complex__()`` method is now looked up on the class of instances to
3590 make it consistent with other special methods.
Benjamin Petersonecdae192010-01-04 00:43:01 +00003591
Antoine Pitrou5b7139a2010-01-02 21:12:58 +00003592- Issue #7462: Implement the stringlib fast search algorithm for the `rfind`,
3593 `rindex`, `rsplit` and `rpartition` methods. Patch by Florent Xicluna.
3594
Mark Dickinson1b34d252010-01-01 17:27:30 +00003595- Issue #5080: A number of functions and methods previously produced a
Georg Brandlba83f822010-03-14 09:50:54 +00003596 DeprecationWarning when passed a float argument where an integer was expected.
3597 These functions and methods now raise TypeError instead. The majority of the
3598 effects of this change are in the extension modules, but some core functions
3599 and methods are affected: notably the 'chr', 'range' and 'xrange' builtins,
3600 and many unicode/str methods.

Amaury Forgeot d'Arc8645a5c2009-12-29 22:03:38 +00003610- Issue #7413: Passing '\0' as the separator to datetime.datetime.isoformat()
3611 used to drop the time part of the result.
3612
Georg Brandlba83f822010-03-14 09:50:54 +00003613- Issue #1811: Improve accuracy and cross-platform consistency for true division
3614 of integers: the result of a/b is now correctly rounded for ints a and b (at
3615 least on IEEE 754 platforms), and in particular does not depend on the
3616 internal representation of a long.
Mark Dickinson46572832009-12-27 14:55:57 +00003617
Georg Brandlba83f822010-03-14 09:50:54 +00003618- Issue #6108: ``unicode(exception)`` and ``str(exception)`` should return the
3619 same message when only ``__str__()`` (and not ``__unicode__()``) is overridden
3620 in the subclass.

Ronald Oussoren92919a62009-12-24 13:30:58 +00003623 executables on OSX.
3624
Georg Brandlba83f822010-03-14 09:50:54 +00003625 These executables now work properly with the arch(1) command: ``arch -ppc
3626 python`` will start a universal binary version of python in PPC mode (unlike
3627 previous releases).

Georg Brandlba83f822010-03-14 09:50:54 +00003650 renaming of `cPickle` to `pickle`. The warning was annoying since there's no

3688 the same as passing no argument.
3689

Georg Brandlba83f822010-03-14 09:50:54 +00003783- Issue #7117: ``repr(x)`` for a float x returns a result based on the shortest
3784 decimal string that's guaranteed to round back to x under correct rounding
3785 (with round-half-to-even rounding mode). Previously it gave a string based on
3786 rounding x to 17 decimal digits. repr(x) for a complex number behaves
3787 similarly. On platforms where the correctly-rounded strtod and dtoa code is
3788 not supported (see below), repr is unchanged.

Georg Brandlba83f822010-03-14 09:50:54 +00003790- Issue #7117: On almost all platforms: float-to-string and string-to-float
3791 conversions within Python are now correctly rounded. Places these conversions
3792 occur include: str for floats and complex numbers; the float and complex
3793 constructors; old-style and new-style numeric formatting; serialization and
3794 deserialization of floats and complex numbers using marshal, pickle and json;
3795 parsing of float and imaginary literals in Python code; Decimal-to-float
3796 conversion.
Mark Dickinsonb678de82009-11-19 18:41:49 +00003797
Georg Brandlba83f822010-03-14 09:50:54 +00003798 The conversions use a Python-adapted version of David Gay's well-known dtoa.c,
3799 providing correctly-rounded strtod and dtoa C functions. This code is
3800 supported on Windows, and on Unix-like platforms using gcc, icc or suncc as
3801 the C compiler. There may be a small number of platforms on which correct
3802 operation of this code cannot be guaranteed, so the code is not used: notably,
3803 this applies to platforms where the C double format is not IEEE 754 binary64,
3804 and to platforms on x86 hardware where the x87 FPU is set to 64-bit precision
3805 and Python's configure script is unable to determine how to change the FPU
3806 precision. On these platforms conversions use the platform strtod and dtoa,
3807 as before.
Mark Dickinsonb678de82009-11-19 18:41:49 +00003808
Georg Brandlba83f822010-03-14 09:50:54 +00003809- Issue #7117: Backport round implementation from Python 3.x. ``round()`` now
3810 uses the correctly-rounded string <-> float conversions described above (when
3811 available), and so produces correctly rounded results that will display nicely
3812 under the float repr. There are two related small changes: (1) round now
3813 accepts any class with an ``__index__()`` method for its second argument (but
3814 no longer accepts floats for the second argument), and (2) an excessively
3815 large second integer argument (e.g., ``round(1.234, 10**100)``) no longer
3816 raises an exception.

Georg Brandlba83f822010-03-14 09:50:54 +00004034 untrackable objects are not tracked by the garbage collector. This can reduce
4035 the size of collections and therefore the garbage collection overhead on
4036 long-running programs, depending on their particular use of datatypes.

Georg Brandlba83f822010-03-14 09:50:54 +00004042- Issue #4258: Make it possible to use base 2**30 instead of base 2**15 for the
4043 internal representation of integers, for performance reasons. Base 2**30 is
4044 enabled by default on 64-bit machines. Add --enable-big-digits option to
4045 configure, which overrides the default. Add sys.long_info structseq to
4046 provide information about the internal format.

Georg Brandlba83f822010-03-14 09:50:54 +00004109- Issue #1180193: When importing a module from a .pyc (or .pyo) file with an
4110 existing .py counterpart, override the co_filename attributes of all code
4111 objects if the original filename is obsolete (which can happen if the file has

4166
Georg Brandlba83f822010-03-14 09:50:54 +00004167- Issue #4233: Changed semantic of ``_fileio.FileIO``'s ``close()`` method on
4168 file objects with closefd=False. The file descriptor is still kept open but
4169 the file object behaves like a closed file. The ``FileIO`` object also got a
4170 new readonly attribute ``closefd``.

4189
Benjamin Peterson399b1fe2008-10-25 02:53:28 +00004190- Using ``nonlocal`` as a variable name will now raise a Py3k SyntaxWarning

Georg Brandlba83f822010-03-14 09:50:54 +00004193- On windows, ``os.chdir()`` given unicode was not working if
4194 GetCurrentDirectoryW returned a path longer than MAX_PATH. (But It's doubtful
4195 this code path is really executed because I cannot move to such directory on
4196 win2k)

Georg Brandlba83f822010-03-14 09:50:54 +00004198- Issue #4069: When ``set.remove(element)`` is used with a set element, the
4199 element is temporarily replaced with an equivalent frozenset. But the
4200 eventual KeyError would always report the empty ``frozenset()`` as the missing
4201 key. Now it correctly refers to the initial element.

Walter Dörwalded960ac2009-05-03 22:36:33 +00004221- Issue #5108: Handle %s like %S and %R in PyUnicode_FromFormatV(): Call
4222 PyUnicode_DecodeUTF8() once, remember the result and output it in a second
4223 step. This avoids problems with counting UTF-8 bytes that ignores the effect
4224 of using the replace error handler in PyUnicode_DecodeUTF8().
4225
Walter Dörwald726ba8e2009-05-06 14:32:35 +00004226- Issue #3739: The unicode-internal encoder now reports the number of characters

Georg Brandlba83f822010-03-14 09:50:54 +00004229- Issue #2422: When compiled with the ``--with-valgrind`` option, the pymalloc

Georg Brandlba83f822010-03-14 09:50:54 +00005396 - If x is not an int, long or float, then packing x will always result in
5397 struct.error. Previously an x with an __int__ method could be packed by
5398 'b', 'B', 'h', 'H', 'i', 'l', '*b', '*h' ,'*i', '*l', and an x with a
5399 __long__ method could be packed by 'q', 'Q', '*q', '*Q'; for x with
5400 neither __int__ nor __long__, TypeError used to be raised (with a
5401 confusing error message) for 'I', 'L', '*B', '*H', '*I', '*L', and
5402 struct.error in other cases.

Georg Brandlba83f822010-03-14 09:50:54 +00005404 Note: as of Python 2.7 beta 1, the above is out of date. In 2.7 beta 1, any
5405 argument with an __int__ method can be packed, but use of this feature
5406 triggers a DeprecationWarning.

Amaury Forgeot d'Arc05e34492008-09-10 22:04:45 +00005599- Issue #3743: In a few places, PY_FORMAT_SIZE_T was incorrectly used with
5600 PyString_FromFormat or PyErr_Format to display size_t values. The macro
5601 PY_FORMAT_SIZE_T is designed to select the correct format for the OS
5602 ``printf`` function, whereas PyString_FromFormat has an independent
5603 implementation and uses "%zd" on all platforms for size_t values.
5604 This makes a difference on win64, where ``printf`` needs "%Id" to display

Brett Cannon1eaf0742008-09-02 01:25:16 +00005700 warnings.catch_warnings() along with some API cleanup. Expanding the tests
5701 for catch_warnings() also led to an improvement in the raising of a
5702 DeprecationWarning related to warnings.warn_explicit().
5703

5726
Amaury Forgeot d'Arc293924b2008-09-02 23:19:56 +00005727- Issue #2975: When compiling several extension modules with Visual Studio 2008
5728 from the same python interpreter, some environment variables would grow
5729 without limit.
5730
Benjamin Peterson37346b22008-08-23 20:27:43 +00005731- Issue #3643: Added a few more checks to _testcapi to prevent segfaults by

Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00005768What's New in Python 2.6 beta 3?
5769================================
5770
Barry Warsaw07a4a382008-08-21 01:15:08 +00005771*Release date: 20-Aug-2008*
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00005772
5773Core and Builtins
5774-----------------
5775
Guido van Rossumf8402962008-08-20 15:01:50 +00005776- Issue #1878: Remove Py_TPFLAGS_HAVE_VERSION_TAG from
5777 Py_TPFLAGS_DEFAULT when not building the core. This means 3rd party
5778 extensions do not automatically benefit from the class attribute
5779 cache; they will have to explicitly add Py_TPFLAGS_HAVE_VERSION_TAG
5780 to their tp_flags field if they care. This is a backwards
5781 compatibility feature; in 3.0, all types will use the cache by
5782 default.
5783
Benjamin Petersonf647dc12008-08-20 01:27:30 +00005784- Keyword arguments can now follow starred arguments. (``f(a, *args,
5785 keyword=23)`` is now valid syntax.)
5786
Thomas Heller0ad5ae02008-08-19 19:25:04 +00005787- ctypes function pointers that are COM methods have a boolean True
5788 value again.
5789
Martin v. Löwisf91d46a2008-08-12 14:49:50 +00005790- Issue #3139: Make buffer-interface thread-safe wrt. PyArg_ParseTuple,
5791 by denying s# to parse objects that have a releasebuffer procedure,
5792 and introducing s*.
5793
Georg Brandl1e13ea92008-08-11 09:07:59 +00005794- Issue #3537: Fix an assertion failure when an empty but presized dict
5795 object was stored in the freelist.
5796
Mark Dickinsonb6467572008-08-04 21:30:09 +00005797- Issue #1481296: Make long(float('nan')) and int(float('nan')) raise
5798 ValueError consistently across platforms.
5799
Amaury Forgeot d'Arc39fd6722008-07-31 21:28:03 +00005800- Issue #3479: On platforms where sizeof(int) is smaller than sizeof(long)
5801 (64bit Unix, for example), unichr() would truncate its argument and return
5802 u'\x00' for unichr(2**32). Now it properly raises an OverflowError.
5803
Neal Norwitze7d8be82008-07-31 17:17:14 +00005804- Apply security patches from Apple.
5805
Amaury Forgeot d'Arc246daed2008-07-31 00:42:16 +00005806- Issue #2542: Now that issubclass() may call arbitrary code, ensure that
5807 PyErr_ExceptionMatches returns 0 when an exception occurs there.
5808
Antoine Pitrou92f82162008-07-25 22:22:08 +00005809- Issue #1819: function calls with several named parameters are now on
5810 average 35% faster (as measured by pybench).
5811
Amaury Forgeot d'Arce4921fe2008-07-21 22:00:38 +00005812- Issue #2378: An unexpected UnboundLocalError or NameError could appear when
5813 the python debugger steps into a class statement: the free variables (local
5814 variables defined in an outer scope) would be deleted from the outer scope.
5815
Gregory P. Smith0470bab2008-07-22 04:46:32 +00005816- Issue #2620: Overflow checking when allocating or reallocating memory
5817 was not always being done properly in some python types and extension
5818 modules. PyMem_MALLOC, PyMem_REALLOC, PyMem_NEW and PyMem_RESIZE have
5819 all been updated to perform better checks and places in the code that
5820 would previously leak memory on the error path when such an allocation
5821 failed have been fixed.

5824-------
5825
Hirokazu Yamamoto838c79f2008-08-20 13:14:07 +00005826- Issue #3612: Added some missing basic types in ctypes.wintypes.
5827
Benjamin Petersone977ad42008-08-20 01:42:01 +00005828- The methods ``is_in_tuple()``, ``is_vararg()``, and ``is_keywordarg()`` of
5829 symtable.Symbol have been deprecated for removal in 3.0 and the next release.
5830
Amaury Forgeot d'Arc351ffb82008-08-18 19:23:47 +00005831- Issue #2234: distutils failed for some versions of the cygwin compiler. The
5832 version reported by these tools does not necessarily follow the python
5833 version numbering scheme, so the module is less strict when parsing it.
5834
Nick Coghlanf70385a2008-08-18 12:42:46 +00005835- Issue #2235: Added Py3k warnings for types which will become unhashable
5836 under the stricter __hash__ inheritance rules in 3.0. Several types
5837 which did not meet the rules for hash invariants and were already
5838 unhashable in 3.0 have now been explicitly flagged as unhashable in
5839 2.6 as well (collections.Mapping, collections.Set, unittest.TestSuite,
5840 xml.dom.minidom.NamedNodeMap, numbers.Number, UserList.UserList)
5841
Brett Cannon88f801d2008-08-18 00:46:22 +00005842- Update __all__ for cookielib, csv, os, urllib2, and weakref to include things

5850
Hirokazu Yamamoto41a81eb2008-08-17 13:10:46 +00005851- Issue #3575: Incremental decoder's decode function now takes bytearray
5852 by using 's*' instead of 't#'.
5853
Mark Dickinson3e4caeb2009-02-21 20:27:01 +00005854- Issue #2222: Fixed reference leak when occurred os.rename()
Hirokazu Yamamoto7f30a682008-08-17 09:46:56 +00005855 fails unicode conversion on 2nd parameter. (windows only)
5856
Georg Brandl222e2082010-08-01 22:27:39 +00005857- Issue #2464: urllib2 now supports a malformation in the URL received
Facundo Batista94f243a2008-08-17 03:38:39 +00005858 in a redirect.
5859

Brett Cannon721b1452008-08-16 22:00:27 +00005861 BaseHTTPServer, cgi (and rfc822), httplib.
Brett Cannonabe423e2008-08-16 21:47:07 +00005862
Facundo Batistaeb90b782008-08-16 14:44:07 +00005863- Issue #2776: fixed small issue when handling an URL with double slash
5864 after a 302 response in the case of not going through a proxy.
5865
Antoine Pitroub90a8be2008-08-15 21:03:21 +00005866- Issue #2676: in the email package, content-type parsing was hanging on
5867 pathological input because of quadratic or exponential behaviour of a
5868 regular expression.
5869
Antoine Pitrou11ec65d2008-08-14 21:04:30 +00005870- Issue #3476: binary buffered reading through the new "io" library is now
5871 thread-safe.
5872
Brett Cannonbf3157b2008-08-14 05:00:03 +00005873- Silence the DeprecationWarning of rfc822 when it is imported by mimetools
5874 since mimetools itself is deprecated. Because modules are cached, all
5875 subsequent imports of rfc822 will not raise a visible DeprecationWarning.
5876
Antoine Pitrou9fcd4b32008-08-11 17:21:36 +00005877- Issue #3134: shutil referenced undefined WindowsError symbol.
5878
Robert Schuppenies14646332008-08-10 11:01:53 +00005879- Issue #1342811: Fix leak in Tkinter.Menu.delete. Commands associated to
5880 menu entries were not deleted.
5881
Brett Cannon83e81842008-08-09 23:30:55 +00005882- Copied the implementation of reduce() to _functools.reduce() to have a
5883 version that did not raise a DeprecationWarning under -3.
5884
Antoine Pitrou76b8bee2008-08-09 17:27:23 +00005885- Issue #3205: When iterating over a BZ2File fails allocating memory, raise
5886 a MemoryError rather than silently stop the iteration.
5887
Guido van Rossum59ce9012008-08-09 14:55:34 +00005888- Issue #3487: sre "bytecode" validator. Passing invalid "re-bytecode"
5889 to _sre.compile() will now be rejected. This should not affect anybody
5890 since the re.compile() function never generates invalid re-bytecode.
5891
Skip Montanaroa032bf42008-08-08 22:52:51 +00005892- Issue #3436: Make csv.DictReader's fieldnames attribute a property so that
5893 upon first access it can be automatically initialized from the csv file if
5894 it wasn't initialized during instantiation.
5895
Brett Cannon3aa2a492008-08-06 22:28:09 +00005896- Issue #2338: Create imp.reload() to help with transitioning to Python 3.0 as
5897 the reload() built-in has been removed.
5898
Brett Cannon7e30b672008-08-04 21:52:25 +00005899- Changed code in the following modules/packages to remove warnings raised
Brett Cannonc1b76e42008-08-09 23:06:16 +00005900 while running under the ``-3`` flag: aifc, asynchat, asyncore, bdb, bsddb,

Antoine Pitroude781a42008-08-09 12:43:23 +00005911 asking for a specific length. This problem only affected files opened
5912 using the new "io" module, not the built-in open() function.
Benjamin Peterson01a24322008-07-28 23:35:27 +00005913

Nick Coghlan2a0c2b12008-08-04 12:47:17 +00005956- Issue #643841: The language reference now provides more detailed
5957 coverage of the lookup process for special methods. The disclaimers
5958 regarding lack of coverage of new-style classes have also been
5959 removed, since the coverage is now fairly reasonable.

Raymond Hettingere3ae6552008-06-20 04:18:15 +00005962What's New in Python 2.6 beta 2?
5963================================
5964
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00005965*Release date: 17-Jul-2008*
5966
Raymond Hettingere3ae6552008-06-20 04:18:15 +00005967Core and Builtins
5968-----------------
5969
Georg Brandl3e483f62008-07-16 22:57:41 +00005970- Issue #3156: Fix inconsistent behavior of the bytearray type: all
5971 its methods now allow for items objects that can be converted to
5972 an integer using operator.index().
5973
Mark Dickinson64b7e502008-07-16 09:40:03 +00005974- Issue #3360: Fix incorrect parsing of '020000000000.0', which
5975 produced a ValueError instead of giving the correct float.
5976
Eric Smitha5fa5a22008-07-16 00:11:49 +00005977- Issue #3083: Add alternate (#) formatting for bin, oct, hex output
5978 for str.format(). This adds the prefix 0b, 0o, or 0x, respectively.
5979
Mark Dickinson7103aa42008-07-15 19:08:33 +00005980- Issue #3008: the float type has a new instance method 'float.hex'
5981 and a new class method 'float.fromhex' to convert floating-point
5982 numbers to and from hexadecimal strings, respectively.
5983
Nick Coghlan6d6bd442008-07-15 15:40:22 +00005984- Issue #2235: __hash__ is once again inherited by default. To allow
5985 collections.Hashable to remain meaningful in the presence of the
5986 default hash implementation (object.__hash__), it is now possible
5987 to explicit block inheritance of hash by setting __hash__=None at
5988 the Python level, or tp_hash=PyObject_HashNotImplemented at the C
5989 level.
5990
Nick Coghlanb028f502008-07-13 14:52:36 +00005991- Issue #3221: Issue a RuntimeWarning instead of raising SystemError if
5992 the parent module cannot be found while performing an absolute import.
5993 This means that an incorrectly defined __package__ attribute will
5994 now only prevent relative imports in that module rather than causing
5995 all imports from that module to fail.
5996
Nick Coghlan14ff9942008-07-08 14:21:42 +00005997- Issue #2517: Allow unicode messages in Exceptions again by correctly
5998 bypassing the instance dictionary when looking up __unicode__ on
5999 new-style classes.
6000
Amaury Forgeot d'Arcbdd941f2008-07-01 20:38:04 +00006001- Issue #3242: Fix a crash inside the print statement, if sys.stdout is
6002 set to a custom object whose write() method happens to install
6003 another file in sys.stdout.
6004
Amaury Forgeot d'Arc1f40c8a2008-06-30 22:42:40 +00006005- Issue #3088: Corrected a race condition in classes derived from
6006 threading.local: the first member set by a thread could be saved in
6007 another thread's dictionary.
6008
Mark Dickinson1ec2fcd2008-06-20 14:53:43 +00006009- Issue #3004: Minor change to slice.indices(): the start and stop
6010 arguments are now treated identically, making the behaviour easier
6011 to describe and understand. For example, slice(None, -10,
6012 1).indices(9) now returns (0, 0, 1) instead of (0, -1, 1), and
6013 slice(None, 10, -1).indices(10) returns (9, 9, -1) instead of (9,
6014 10, -1).
6015
Georg Brandl278fc502008-07-19 12:46:12 +00006016- Issue #3219: Calling a function with repeated keyword arguments,
6017 f(a=2, a=23), would not cause a syntax error. This was a regression
6018 from 2.4 caused by the switch to the new compiler.
Benjamin Peterson175e4d92008-07-01 19:34:52 +00006019
Georg Brandl278fc502008-07-19 12:46:12 +00006020- Issue #2862: Make int and float freelist management consistent with
6021 other freelists. Changes their CompactFreeList apis into
6022 ClearFreeList apis and calls them via gc.collect().
Gregory P. Smith2fe77062008-07-06 03:35:58 +00006023

6025-------
6026
Thomas Heller57adf222008-08-14 19:10:48 +00006027- Issue #3554: ctypes.string_at and ctypes.wstring_at did call Python
6028 api functions without holding the GIL, which could lead to a fatal
6029 error when they failed.
6030
Martin v. Löwisaabf4042008-08-02 07:20:25 +00006031- Issue #799428: Fix Tkinter.Misc._nametowidget to unwrap Tcl command objects.

Jesse Noller13e9d582008-07-16 14:32:36 +00006039- Issue #3125: Remove copy_reg in multiprocessing and replace it with
6040 ForkingPickler.register() to resolve conflict with ctypes.
6041
Vinay Sajip51e65192008-07-18 09:01:10 +00006042- Issue #3090: Fixed ARCHFLAGS parsing on OS/X
Jesse Noller13e9d582008-07-16 14:32:36 +00006043
Thomas Heller880f5292008-07-15 19:39:38 +00006044- Issue #3313: Fixed a crash when a failed dlopen() call does not set
6045 a valid dlerror() message.
6046
Thomas Heller2bad6572008-07-15 17:19:50 +00006047- Issue #3258: Fixed a crash when a ctypes POINTER type to an
6048 incomplete structure was created.
6049

6053
Andrew M. Kuchlingcc3f2b12008-07-10 14:43:31 +00006054- Issue #3301: Bisect module behaved badly when lo was negative.
Raymond Hettinger3cd1e422008-07-10 14:03:19 +00006055
Amaury Forgeot d'Arc0f7cddc2008-07-06 21:34:39 +00006056- Issue #839496: SimpleHTTPServer used to open text files in text mode. This is
6057 both unnecessary (HTTP allows text content to be sent in several forms) and
Andrew M. Kuchlingcc3f2b12008-07-10 14:43:31 +00006058 wrong because the actual transmitted size could differ from the
Amaury Forgeot d'Arc0f7cddc2008-07-06 21:34:39 +00006059 content-length. The problem had been corrected in the 2.4 branch, but never
6060 merged into trunk.
6061
Georg Brandle78fbcc2008-07-05 10:13:36 +00006062- Issue #2663: add filtering capability to shutil.copytree().

Vinay Sajip51e65192008-07-18 09:01:10 +00006070 Zip files with archives by setting the 'comment' attribute of a ZipFile.
Martin v. Löwis8c436412008-07-03 12:51:14 +00006071
Vinay Sajip51e65192008-07-18 09:01:10 +00006072- Issue #449227: The rlcompleter module now adds "(" to callable objects
Andrew M. Kuchlingcc3f2b12008-07-10 14:43:31 +00006073 when completed.
Facundo Batista66c52772008-07-02 16:52:55 +00006074
Nick Coghlanc060b0e2008-07-02 13:09:19 +00006075- Issue #3190: Pydoc now hides the automatic module attribute __package__ (the
6076 handling is now the same as that of other special attributes like __name__).
6077
Brett Cannon8bb8fa52008-07-02 01:57:08 +00006078- Issue #2885 (partial): The urllib.urlopen() function has been deprecated for
6079 removal in Python 3.0 in favor of urllib2.urlopen().

Georg Brandl3ee81df2008-05-17 18:14:43 +00006530- Issue #1631171: Re-implement the 'warnings' module in C (the
6531 original Python code has been kept as backup). This will allow for
6532 using the 'warning's machinery in such places as the parser where
6533 use of pure Python code is not possible. Both the ``showarning()``
6534 and ``formatwarning()`` gain an optional 'line' argument which is
6535 not called by default for backwards-compatibility reasons. Setting
6536 ``warnings.showwarning()`` to an implementation that lacks support
6537 for the ``line`` argument will raise a DeprecationWarning.

Georg Brandl3ee81df2008-05-17 18:14:43 +00006600- Issue #2550: The approach used by client/server code for obtaining
6601 ports to listen on in network-oriented tests has been refined in an
6602 effort to facilitate running multiple instances of the entire
6603 regression test suite in parallel without issue.
6604 test_support.bind_port() has been fixed such that it will always
6605 return a unique port -- which wasn't always the case with the
6606 previous implementation, especially if socket options had been set
6607 that affected address reuse (i.e. SO_REUSEADDR, SO_REUSEPORT). The
6608 new implementation of bind_port() will actually raise an exception
6609 if it is passed an AF_INET/SOCK_STREAM socket with either the
6610 SO_REUSEADDR or SO_REUSEPORT socket option set. Furthermore, if
6611 available, bind_port() will set the SO_EXCLUSIVEADDRUSE option on
6612 the socket it's been passed. This currently only applies to
6613 Windows. This option prevents any other sockets from binding to the
6614 host/port we've bound to, thus removing the possibility of the
6615 'non-deterministic' behaviour, as Microsoft puts it, that occurs
6616 when a second SOCK_STREAM socket binds and accepts to a host/port
6617 that's already been bound by another socket. The optional preferred
6618 port parameter to bind_port() has been removed. Under no
6619 circumstances should tests be hard coding ports!
6620
6621 test_support.find_unused_port() has also been introduced, which will
6622 pass a temporary socket object to bind_port() in order to obtain an
6623 unused port. The temporary socket object is then closed and
6624 deleted, and the port is returned. This method should only be used
6625 for obtaining an unused port in order to pass to an external program
6626 (i.e. the -accept [port] argument to openssl's s_server mode) or as
6627 a parameter to a server-oriented class that doesn't give you direct
6628 access to the underlying socket used.
6629
6630 Finally, test_support.HOST has been introduced, which should be used
6631 for the host argument of any relevant socket calls (i.e. bind and
6632 connect).
Trent Nelsone41b0062008-04-08 23:47:30 +00006633
6634 The following tests were updated to following the new conventions:
Georg Brandl3ee81df2008-05-17 18:14:43 +00006635 test_socket, test_smtplib, test_asyncore, test_ssl, test_httplib,
Trent Nelsone41b0062008-04-08 23:47:30 +00006636 test_poplib, test_ftplib, test_telnetlib, test_socketserver,
6637 test_asynchat and test_socket_ssl.
6638
Georg Brandl3ee81df2008-05-17 18:14:43 +00006639 It is now possible for multiple instances of the regression test
6640 suite to run in parallel without issue.

Eric Smitha73fbe72008-02-23 03:09:44 +00006919- Added the future_builtins module, which contains hex() and oct().
6920 These are the PEP 3127 version of these functions, designed to be
6921 compatible with the hex() and oct() builtins from Python 3.0. They
6922 differ slightly in their output formats from the existing, unchanged
6923 Python 2.6 builtins. The expected usage of the future_builtins
6924 module is:
6925 from future_builtins import hex, oct
6926
Eric Smith7ef40bf2008-02-20 23:34:22 +00006927- Issue #1600: Modifed PyOS_ascii_formatd to use at most 2 digit
6928 exponents for exponents with absolute value < 100. Follows C99
6929 standard. This is a change on Windows, which would use 3 digits.
6930 Also, added 'n' to the formats that PyOS_ascii_formatd understands,
6931 so that any alterations it does to the resulting string will be
6932 available in stringlib/formatter.h (for float.__format__).
6933
Eric Smith5a3c1352008-02-19 13:21:56 +00006934- Implemented PEP 3101, Advanced String Formatting. This adds a new
6935 builtin format(); a format() method for str and unicode; a
6936 __format__() method to object, str, unicode, int, long, float, and
6937 datetime; the class string.Formatter; and the C API
6938 PyObject_Format().
6939
Georg Brandl3ee81df2008-05-17 18:14:43 +00006940- Fixed several potential crashes, all caused by specially crafted
6941 __del__ methods exploiting objects in temporarily inconsistent
6942 state.
Amaury Forgeot d'Arc632fad32008-02-16 20:55:24 +00006943
Vinay Sajipb7edfc42008-04-02 21:10:23 +00006944- Issue #2115: Important speedup in setting __slot__ attributes. Also
Georg Brandl3ee81df2008-05-17 18:14:43 +00006945 prevent a possible crash: an Abstract Base Class would try to access
6946 a slot on a registered virtual subclass.

Georg Brandl3ee81df2008-05-17 18:14:43 +00006951- Clear all free lists during a gc.collect() of the highest generation
6952 in order to allow pymalloc to free more arenas. Python may give back
6953 memory to the OS earlier.
Christian Heimes3b718a72008-02-14 12:47:33 +00006954
Georg Brandl3ee81df2008-05-17 18:14:43 +00006955- Issue #2045: Fix an infinite recursion triggered when printing a
6956 subclass of collections.defaultdict, if its default_factory is set
6957 to a bound method.
Amaury Forgeot d'Arcb01aa432008-02-08 00:56:02 +00006958
Christian Heimesf75dbef2008-02-08 00:11:31 +00006959- Fixed a minor memory leak in dictobject.c. The content of the free
6960 list was not freed on interpreter shutdown.
6961
Georg Brandl21e99f42010-03-07 15:23:59 +00006962- Limit free list of method and built-in function objects to 256

Christian Heimes6075a822008-02-06 12:44:34 +00006964
Georg Brandl3ee81df2008-05-17 18:14:43 +00006965- Patch #1953: Added ``sys._compact_freelists()`` and the C API
6966 functions ``PyInt_CompactFreeList`` and ``PyFloat_CompactFreeList``
Christian Heimes422051a2008-02-04 18:00:12 +00006967 to compact the internal free lists of pre-allocted ints and floats.
6968
Georg Brandl3ee81df2008-05-17 18:14:43 +00006969- Issue #1983: Fixed return type of fork(), fork1() and forkpty()
6970 calls. Python expected the return type int but the fork familie
6971 returns pi_t.
Christian Heimes951cc0f2008-01-31 23:08:23 +00006972

Georg Brandl3ee81df2008-05-17 18:14:43 +00006985- Patch #1473257: generator objects gain a gi_code attribute. This is
6986 the same object as the func_code attribute of the function that
6987 produced the generator.
Georg Brandl0cdf9a32008-01-26 14:14:20 +00006988
Georg Brandl3ee81df2008-05-17 18:14:43 +00006989- Issue #1920: "while 0" statements were completely removed by the
6990 compiler, even in the presence of an "else" clause, which is
6991 supposed to be run when the condition is false. Now the compiler
6992 correctly emits bytecode for the "else" suite.
Amaury Forgeot d'Arc31eaafe2008-01-24 22:59:25 +00006993

7001
Georg Brandl3ee81df2008-05-17 18:14:43 +00007002- Issue #1915: Python compiles with --enable-unicode=no again. However
Christian Heimes082c9b02008-01-23 14:20:50 +00007003 several extension methods and modules do not work without unicode
7004 support.
7005
Georg Brandl26543b12008-01-21 18:36:51 +00007006- Issue #1882: when compiling code from a string, encoding cookies in the

7008
Georg Brandl14404b62008-01-19 19:27:05 +00007009- Issue #1679: "0x" was taken as a valid integer literal.
7010
Georg Brandl6caad7d2008-01-26 14:19:22 +00007011- Issue #1865: ``bytes`` as an alias for ``str`` and b"" as an alias "" were
Christian Heimes288e89a2008-01-18 18:24:07 +00007012 added.
7013
Christian Heimesc94e2b52008-01-14 04:13:37 +00007014- sys.float_info / PyFloat_GetInfo: The floating point information
7015 object was converted from a dict to a specialized structseq object.
7016
Georg Brandl3ee81df2008-05-17 18:14:43 +00007017- Patch #1816: Added sys.flags structseq. It exposes the status of
7018 most command line arguments and PYTHON* environment variables.
Christian Heimesf31b69f2008-01-14 03:42:48 +00007019
Georg Brandl3ee81df2008-05-17 18:14:43 +00007020- Objects/structseq.c: Implemented new structseq representation. The

Georg Brandlaed6c662008-01-07 17:25:53 +00007030- Patch #1668: renamed THREADDEBUG envvar to PYTHONTHREADDEBUG.
7031
Georg Brandl3ee81df2008-05-17 18:14:43 +00007032- Patch #602345: Add -B command line option, PYTHONDONTWRITEBYTECODE
7033 envvar and sys.dont_write_bytecode attribute. All these can be set
7034 to forbid Python to attempt to write compiled bytecode files.

Georg Brandl3ee81df2008-05-17 18:14:43 +00007036- Improve some exception messages when Windows fails to load an
7037 extension module. Now we get for example '%1 is not a valid Win32
7038 application' instead of 'error code 193'.

Christian Heimes0a8143f2007-12-18 23:22:54 +00007045- Issue #1635: Platform independent creation and representation of NaN
Georg Brandl3ee81df2008-05-17 18:14:43 +00007046 and INF. float("nan"), float("inf") and float("-inf") now work on
7047 every platform with IEEE 754 semantics.

7051 dictionary size. There is a new opcode, STORE_MAP, for adding
7052 entries to the dictionary.

7082 file can now be directly executed by passing their name to the
7083 interpreter. The directory/zipfile is automatically inserted as the
7084 first entry in sys.path.

7095
Georg Brandl21e99f42010-03-07 15:23:59 +00007096- The enumerate() built-in function is no longer bounded to sequences
Georg Brandl3ee81df2008-05-17 18:14:43 +00007097 smaller than LONG_MAX. Formerly, it raised an OverflowError. Now,
7098 automatically shifts from ints to longs.
Raymond Hettinger8f669372007-10-03 21:18:11 +00007099
Georg Brandl3ee81df2008-05-17 18:14:43 +00007100- Issue #1686386: Tuple's tp_repr did not take into account the
7101 possibility of having a self-referential tuple, which is possible
7102 from C code. Nor did object's tp_str consider that a type's tp_str
7103 could do something that could lead to an inifinite recursion.
7104 Py_ReprEnter() and Py_EnterRecursiveCall(), respectively, fixed the
7105 issues.
Brett Cannon0b14f242007-09-30 19:45:10 +00007106
Georg Brandl3ee81df2008-05-17 18:14:43 +00007107- Issue #1164: It was possible to trigger deadlock when using the
7108 'print' statement to write to a file since the GIL was not released
7109 as needed. Now PyObject_Print() does the right thing along with
7110 various tp_print implementations of the built-in types and those in
7111 the collections module.
Brett Cannon01531592007-09-17 03:28:34 +00007112
Georg Brandl3ee81df2008-05-17 18:14:43 +00007113- Issue #1147: Exceptions were directly allowing string exceptions in

Brett Cannon1e534b52007-09-07 04:18:30 +00007120- Issue #1202533: Fix infinite recursion calls triggered by calls to
Georg Brandl3ee81df2008-05-17 18:14:43 +00007121 PyObject_Call() never calling back out to Python code to trigger
7122 recursion depth updates/checks. Required the creation of a static
7123 RuntimeError instance in case normalizing an exception put the
7124 recursion check value past its limit. Fixes crashers
7125 infinite_rec_(1|2|4|5).py.

Neal Norwitz0ac60192007-05-27 04:08:54 +00007140- Add new attribute names for function objects. All the func_* become
Georg Brandl3ee81df2008-05-17 18:14:43 +00007141 __*__ attributes. (Some already existed, e.g., __doc__ and
7142 __name__.)

7146
Georg Brandl2134e752007-05-21 20:34:16 +00007147- Patch #1686487: you can now pass any mapping after '**' in function
7148 calls.
7149
Collin Winter62903052007-05-18 23:11:24 +00007150- except clauses may now be spelled either "except E, target:" or
Georg Brandl3ee81df2008-05-17 18:14:43 +00007151 "except E as target:". This is to provide forwards compatibility
7152 with Python 3.0.

Vinay Sajip8549ce32007-05-06 17:53:37 +00007159- When __slots__ are set to a unicode string, make it work the same as
Neal Norwitzcbd9ee62007-04-14 05:25:50 +00007160 setting a plain string, ie don't expand to single letter identifiers.
7161
Raymond Hettinger13936692007-04-11 18:40:58 +00007162- Request #1191699: Slices can now be pickled.
7163
Raymond Hettinger4db5fe92007-04-12 04:10:00 +00007164- Request #1193128: str.translate() now allows a None argument for
7165 translations that only remove characters without re-mapping the
7166 remaining characters.
7167
Georg Brandl5cb76c12007-03-21 09:00:39 +00007168- Patch #1682205: a TypeError while unpacking an iterable is no longer

7172
Guido van Rossum143b5642007-03-23 04:58:42 +00007173- Bug #1683368: The object.__init__() and object.__new__() methods are
7174 now stricter in rejecting excess arguments. The only time when
7175 either allows excess arguments is when it is not overridden and the
7176 other one is. For backwards compatibility, when both are
7177 overridden, it is a deprecation warning (for now; maybe a Py3k
Guido van Rossum234b1ff2007-03-23 19:39:01 +00007178 warning later). Also, type.__init__() insists on the same signature
7179 as supported by type.__new__().
Guido van Rossum143b5642007-03-23 04:58:42 +00007180
Georg Brandl3ee81df2008-05-17 18:14:43 +00007181- Patch #1675423: PyComplex_AsCComplex() now tries to convert an
7182 object to complex using its __complex__() method before falling back
7183 to the __float__() method. Therefore, the functions in the cmath
7184 module now can operate on objects that define a __complex__()
7185 method.

7202
Georg Brandl7b9c5552007-03-12 14:30:05 +00007203- Bug #1678647: write a newline after printing an exception in any
7204 case, even when converting the value to a string failed.
7205
Georg Brandl871f1bc2007-03-12 13:17:36 +00007206- The dir() function has been extended to call the __dir__() method on
Georg Brandl3ee81df2008-05-17 18:14:43 +00007207 its argument, if it exists. If not, it will work like before. This
7208 allows customizing the output of dir() in the presence of a
7209 __getattr__().

7218 parthensized forms. This means complex(repr(x)) now works instead of
7219 raising a ValueError.
Collin Wintere38051d2007-03-09 20:33:07 +00007220
Georg Brandlaa2321b2007-03-07 00:40:28 +00007221- Patch #703779: unset __file__ in __main__ after running a file. This
Georg Brandl3ee81df2008-05-17 18:14:43 +00007222 makes the filenames the warning module prints much more sensible
7223 when a PYTHONSTARTUP file is used.

Georg Brandl0fca97a2007-03-05 22:28:08 +00007236- Patch #1674228: when assigning a slice (old-style), check for the
7237 sq_ass_slice instead of the sq_slice slot.
7238
Georg Brandl3ee81df2008-05-17 18:14:43 +00007239- When printing an unraisable error, don't print exceptions. before

Georg Brandl3ee81df2008-05-17 18:14:43 +00007774 AttributeError instead of an IOError when the server's response
7775 didn't contain a valid HTTP status line.
Georg Brandlf66b6032007-03-14 08:27:52 +00007776

7791
Georg Brandl3ee81df2008-05-17 18:14:43 +00007792- Patch #1530482: add pydoc.render_doc() which returns the

7807
Georg Brandl92a6bae2007-03-13 17:43:32 +00007808- Patch #1603688: ConfigParser.SafeConfigParser now checks values that
Georg Brandl3ee81df2008-05-17 18:14:43 +00007809 are set for invalid interpolation sequences that would lead to
7810 errors on reading back those values.

7853 returned string up to the first NUL character.

7864
Georg Brandl3ee81df2008-05-17 18:14:43 +00007865- unittest now verifies more of its assumptions. In particular,
7866 TestCase and TestSuite subclasses (not instances) are no longer
7867 accepted in TestSuite.addTest(). This should cause no
7868 incompatibility since it never made sense with ordinary subclasses
7869 -- the failure just occurred later, with a more cumbersome
7870 exception.

7880
Georg Brandl3ee81df2008-05-17 18:14:43 +00007881- Patch #1673619: setup.py identifies extension modules it doesn't

Gregory P. Smithec10a4a2007-11-05 02:32:26 +00008258- pybsddb.sf.net Bug #477182: Load the database flags at database open
Georg Brandl3ee81df2008-05-17 18:14:43 +00008259 time so that opening a database previously created with the DB_DUP
8260 or DB_DUPSORT flag set will keep the proper behavior on subsequent
8261 opens. Specifically: dictionary assignment to a DB object will
8262 replace all values for a given key when the database allows
8263 duplicate values. DB users should use DB.put(k, v) when they want
8264 to store duplicates; not DB[k] = v.

8271 characters with ASCII value less than 32. Also, it correctly quotes
8272 dots only if they occur on a single line, as opposed to the previous
8273 behavior of quoting dots if they are the second character of any
8274 line.

8620 of w# format code incorrectly truncated the length to an int, even
8621 when PY_SSIZE_T_CLEAN is set. The str.decode method used to return
8622 incorrect results with huge strings.

Georg Brandl3ee81df2008-05-17 18:14:43 +00008652- Added case insensitive comparison methods ``PyOS_stricmp(char*,
8653 char*)`` and ``PyOS_strnicmp(char*, char*, Py_ssize_t)``.
