Ned Deily0d0ea482012-02-10 12:59:06 +0100793- Issue #13590: On OS X 10.7 and 10.6 with Xcode 4.2, building
794 Distutils-based packages with C extension modules may fail because
795 Apple has removed gcc-4.2, the version used to build python.org
796 64-bit/32-bit Pythons. If the user does not explicitly override
797 the default C compiler by setting the CC environment variable,
798 Distutils will now attempt to compile extension modules with clang
799 if gcc-4.2 is required but not found. Also as a convenience, if
800 the user does explicitly set CC, substitute its value as the default
801 compiler in the Distutils LDSHARED configuration variable for OS X.
802 (Note, the python.org 32-bit-only Pythons use gcc-4.0 and the 10.4u
803 SDK, neither of which are available in Xcode 4. This change does not
804 attempt to override settings to support their use with Xcode 4.)

Ned Deily87e82bb2011-06-28 19:52:59 -07001077- Issue #9516: On Mac OS X, change Distutils to no longer globally attempt to
1078 check or set the MACOSX_DEPLOYMENT_TARGET environment variable for the
1079 interpreter process. This could cause failures in non-Distutils subprocesses
1080 and was unreliable since tests or user programs could modify the interpreter
1081 environment after Distutils set it. Instead, have Distutils set the the
1082 deployment target only in the environment of each build subprocess. It is
1083 still possible to globally override the default by setting
1084 MACOSX_DEPLOYMENT_TARGET before launching the interpreter; its value must be
1085 greater or equal to the default value, the value with which the interpreter
1086 was built.

1116 the ticker doesn't have to wind down to zero from the old starting point
1117 before the new interval takes effect. And if the user increases the
1118 interval, it makes sure the new limit takes effect right away rather have an
1119 early task switch before recognizing the new interval.

2041 received. Now sendall() properly calls signal handlers if necessary,
2042 and retries sending if these returned successfully, including on sockets
2043 with a timeout.

2060 by Andrew Bennetts.

2069
Raymond Hettinger20397532010-09-12 02:11:45 +00002070- Issue #9825: removed __del__ from the definition of collections.OrderedDict.
2071 This prevents user-created self-referencing ordered dictionaries from
2072 becoming permanently uncollectable GC garbage. The downside is that
2073 removing __del__ means that the internal doubly-linked list has to wait for
2074 GC collection rather than freeing memory immediately when the refcnt drops
2075 to zero.
2076

2084 original error is re-raised.

2104 falling into recursion.
2105
R. David Murray7c4bf552010-08-25 01:45:57 +00002106- Issue #1194222: email.utils.parsedate now returns RFC2822 compliant four
2107 character years even if the message contains RFC822 two character years.
2108
Daniel Stutzbach91287322010-08-24 21:09:30 +00002109- Issue #8750: Fixed MutableSet's methods to correctly handle

2128
Raymond Hettingera54b2da2010-08-17 19:03:06 +00002129- Issue #9626: the view methods for collections.OrderedDict() were returning

Antoine Pitroucb4f47c2010-08-11 13:40:17 +00002141- Issue #9550: a BufferedReader could issue an additional read when the
2142 original read request had been satisfied, which could block indefinitely
2143 when the underlying raw IO channel was e.g. a socket. Report and original
2144 patch by Jason V. Miller.

2329 compared to other unix systems. In particular, os.getgroups() does
2330 not reflect any changes made using os.setgroups() but basicly always
2331 returns the same information as the id command.
2332
2333 os.getgroups() can now return more than 16 groups on MacOSX.

2537 E.g.: '\xf1\x80AB'.decode('utf-8', 'replace') now returns u'\ufffdAB' and
2538 replaces with U+FFFD only the start byte ('\xf1') and the continuation byte

R. David Murray1a14d3d2010-04-12 16:35:19 +00002847- Issue #7585: difflib context and unified diffs now place a tab between
Georg Brandlfee0f442010-05-22 21:26:21 +00002848 filename and date, conforming to the 'standards' they were originally designed
2849 to follow. This improves compatibility with patch tools.

Mark Dickinsond2f3e3f2010-05-05 22:23:58 +00002895 (Optimization was unintentionally turned on in gcc --with-pydebug builds in
2896 2.7 beta1 as a result of the issue #1628484 fix, combined with autoconf's
2897 strange choice of default CFLAGS produced by AC_PROG_CC for gcc.)

2918-----------------
2919
Philip Jenveyaebbaeb2010-04-06 23:24:45 +00002920- Issue #7301: Add environment variable $PYTHONWARNINGS.
2921
Benjamin Peterson3a1dfa22010-04-06 21:50:00 +00002922- Issue #8329: Don't return the same lists from select.select when no fds are
2923 changed.
2924
Georg Brandlfee0f442010-05-22 21:26:21 +00002925- Issue #8259: ``1L << (2**31)`` no longer produces an 'outrageous shift error'
Mark Dickinson82791672010-04-06 16:47:55 +00002926 on 64-bit machines. The shift count for either left or right shift is
2927 permitted to be up to sys.maxsize.
2928
Benjamin Peterson4ceeeb02010-04-03 22:48:51 +00002929- Ensure that tokenization of identifiers is not affected by locale.
2930
Georg Brandlfee0f442010-05-22 21:26:21 +00002931- Issue #1222585: Added LDCXXSHARED for C++ support. Patch by Arfrever.
Tarek Ziadé00002952010-04-03 08:37:59 +00002932
Benjamin Peterson1c7c11e2010-04-03 01:28:57 +00002933- Raise a TypeError when trying to delete a T_STRING_INPLACE struct member.
2934
Georg Brandlfee0f442010-05-22 21:26:21 +00002935- Issue #7994: Issue a PendingDeprecationWarning if object.__format__ is called
2936 with a non-empty format string. This is an effort to future-proof user
2937 code. If a derived class does not currently implement __format__ but later
2938 adds its own __format__, it would most likely break user code that had
Antoine Pitrou01a196a2011-01-02 20:05:11 +00002939 supplied a format string. This will be changed to a DeprecationWarning in
Georg Brandlfee0f442010-05-22 21:26:21 +00002940 Python 3.3 and it will be an error in Python 3.4.
Eric Smithd44b2fc2010-04-02 12:30:56 +00002941
Antoine Pitroua57df2c2010-03-31 21:32:15 +00002942- Issue #8268: Old-style classes (not just instances) now support weak

2954
Victor Stinner66644262010-03-10 22:30:19 +00002955- Issue #3137: Don't ignore errors at startup, especially a keyboard interrupt
Georg Brandlba83f822010-03-14 09:50:54 +00002956 (SIGINT). If an error occurs while importing the site module, the error is
2957 printed and Python exits. Initialize the GIL before importing the site

2972
Georg Brandlfee0f442010-05-22 21:26:21 +00002973- Issue #8257: The Decimal construct now accepts a float instance directly,
2974 converting that float to a Decimal of equal value:
Mark Dickinson8a950712010-04-03 15:47:46 +00002975
2976 >>> Decimal(1.1)
2977 Decimal('1.100000000000000088817841970012523233890533447265625')
2978
Raymond Hettinger34c35b22010-04-03 10:22:00 +00002979- collections.Counter() now supports a subtract() method.
2980
Georg Brandlfee0f442010-05-22 21:26:21 +00002981- The functools module now has a total_ordering() class decorator to simplify
2982 the specification of rich comparisons.
Raymond Hettingera551f312010-04-04 18:34:45 +00002983
Georg Brandlfee0f442010-05-22 21:26:21 +00002984- The functools module also adds cmp_to_key() as a tool to transition old-style
2985 comparison functions to new-style key-functions.
Raymond Hettingera551f312010-04-04 18:34:45 +00002986
Georg Brandlfee0f442010-05-22 21:26:21 +00002987- Issue #8294: The Fraction constructor now accepts Decimal and float instances
2988 directly.

Georg Brandlfee0f442010-05-22 21:26:21 +00002990- Issue #7279: Comparisons involving a Decimal signaling NaN now signal
2991 InvalidOperation instead of returning False. (Comparisons involving a quiet
2992 NaN are unchanged.) Also, Decimal quiet NaNs are now hashable; Decimal
2993 signaling NaNs remain unhashable.
Mark Dickinsone096e822010-04-02 10:17:07 +00002994
Georg Brandlfee0f442010-05-22 21:26:21 +00002995- Issue #2531: Comparison operations between floats and Decimal instances now
2996 return a result based on the numeric values of the operands; previously they
2997 returned an arbitrary result based on the relative ordering of id(float) and
2998 id(Decimal).
Mark Dickinson99d80962010-04-02 08:53:22 +00002999
Barry Warsawf7f2d6f2010-03-31 21:07:16 +00003000- Issue #8233: When run as a script, py_compile.py optionally takes a single
Georg Brandlfee0f442010-05-22 21:26:21 +00003001 argument `-` which tells it to read files to compile from stdin. Each line is
3002 read on demand and the named file is compiled immediately. (Original patch by
3003 Piotr Ożarowski).
Barry Warsawf7f2d6f2010-03-31 21:07:16 +00003004
Georg Brandlfee0f442010-05-22 21:26:21 +00003005- Issue #3135: Add ``inspect.getcallargs()``, which binds arguments to a

Florent Xicluna58b65662010-03-30 16:29:03 +00003008- Backwards incompatible change: Unicode codepoints line tabulation (0x0B) and
3009 form feed (0x0C) are now considered linebreaks, as specified in Unicode
Georg Brandlfee0f442010-05-22 21:26:21 +00003010 Standard Annex #14. See issue #7643. http://www.unicode.org/reports/tr14/
Florent Xicluna22b24382010-03-30 08:24:06 +00003011
Georg Brandlfee0f442010-05-22 21:26:21 +00003012- Comparisons using one of <, <=, >, >= between a complex instance and a
3013 Fractions instance now raise TypeError instead of returning True/False. This
3014 makes Fraction <=> complex comparisons consistent with int <=> complex, float
3015 <=> complex, and complex <=> complex comparisons.

Georg Brandlfee0f442010-05-22 21:26:21 +00003122 produces a DeprecationWarning in this case. (In Python 2.6, the behaviour was
3123 inconsistent: __int__ was used for some integer codes but not for others, and
3124 the set of integer codes for which it was used differed between native packing
3125 and standard packing.)

Georg Brandlba83f822010-03-14 09:50:54 +00003433 file position when calling `truncate()`. It would previously change the file
3434 position to the given argument, which goes against the tradition of
Antoine Pitrouf3fa0742010-01-31 22:26:04 +00003435 ftruncate() and other truncation APIs. Patch by Pascal Chambon.
3436

3438 class used to represent files stored inside an archive. The new
3439 implementation is significantly faster and can be wrapped in a
3440 ``io.BufferedReader`` object for more speedups. It also solves an issue
3441 where interleaved calls to ``read()`` and ``readline()`` give wrong results.

3454 encoded string for them. This ensures that the upload and register commands
3455 send the correct values to PyPI without any error.

Georg Brandlba83f822010-03-14 09:50:54 +00003726- Issue #7117: ``repr(x)`` for a float x returns a result based on the shortest
3727 decimal string that's guaranteed to round back to x under correct rounding
3728 (with round-half-to-even rounding mode). Previously it gave a string based on
3729 rounding x to 17 decimal digits. repr(x) for a complex number behaves
3730 similarly. On platforms where the correctly-rounded strtod and dtoa code is
3731 not supported (see below), repr is unchanged.
Mark Dickinsonb678de82009-11-19 18:41:49 +00003732
Georg Brandlba83f822010-03-14 09:50:54 +00003733- Issue #7117: On almost all platforms: float-to-string and string-to-float
3734 conversions within Python are now correctly rounded. Places these conversions
3735 occur include: str for floats and complex numbers; the float and complex
3736 constructors; old-style and new-style numeric formatting; serialization and
3737 deserialization of floats and complex numbers using marshal, pickle and json;
3738 parsing of float and imaginary literals in Python code; Decimal-to-float
3739 conversion.
Mark Dickinsonb678de82009-11-19 18:41:49 +00003740
Georg Brandlba83f822010-03-14 09:50:54 +00003741 The conversions use a Python-adapted version of David Gay's well-known dtoa.c,
3742 providing correctly-rounded strtod and dtoa C functions. This code is
3743 supported on Windows, and on Unix-like platforms using gcc, icc or suncc as
3744 the C compiler. There may be a small number of platforms on which correct
3745 operation of this code cannot be guaranteed, so the code is not used: notably,
3746 this applies to platforms where the C double format is not IEEE 754 binary64,
3747 and to platforms on x86 hardware where the x87 FPU is set to 64-bit precision
3748 and Python's configure script is unable to determine how to change the FPU
3749 precision. On these platforms conversions use the platform strtod and dtoa,
3750 as before.

Georg Brandlba83f822010-03-14 09:50:54 +00003752- Issue #7117: Backport round implementation from Python 3.x. ``round()`` now
3753 uses the correctly-rounded string <-> float conversions described above (when
3754 available), and so produces correctly rounded results that will display nicely
3755 under the float repr. There are two related small changes: (1) round now
3756 accepts any class with an ``__index__()`` method for its second argument (but
3757 no longer accepts floats for the second argument), and (2) an excessively
3758 large second integer argument (e.g., ``round(1.234, 10**100)``) no longer
3759 raises an exception.

Georg Brandlba83f822010-03-14 09:50:54 +00003906- Issue #5920: For ``float.__format__()``, change the behavior with the empty
3907 presentation type (that is, not one of 'e', 'f', 'g', or 'n') to be like 'g'
3908 but with at least one decimal point and with a default precision
3909 of 12. Previously, the behavior the same but with a default precision of 6.
3910 This more closely matches ``str()``, and reduces surprises when adding
3911 alignment flags to the empty presentation type. This also affects the new
3912 complex.__format__ in the same way.
3913

Georg Brandlba83f822010-03-14 09:50:54 +00004052- Issue #1180193: When importing a module from a .pyc (or .pyo) file with an
4053 existing .py counterpart, override the co_filename attributes of all code

4109
Georg Brandlba83f822010-03-14 09:50:54 +00004110- Issue #4233: Changed semantic of ``_fileio.FileIO``'s ``close()`` method on
4111 file objects with closefd=False. The file descriptor is still kept open but
4112 the file object behaves like a closed file. The ``FileIO`` object also got a
4113 new readonly attribute ``closefd``.

Benjamin Peterson399b1fe2008-10-25 02:53:28 +00004133- Using ``nonlocal`` as a variable name will now raise a Py3k SyntaxWarning

Georg Brandlba83f822010-03-14 09:50:54 +00004136- On windows, ``os.chdir()`` given unicode was not working if
4137 GetCurrentDirectoryW returned a path longer than MAX_PATH. (But It's doubtful
4138 this code path is really executed because I cannot move to such directory on
4139 win2k)

Georg Brandlba83f822010-03-14 09:50:54 +00004141- Issue #4069: When ``set.remove(element)`` is used with a set element, the
4142 element is temporarily replaced with an equivalent frozenset. But the
4143 eventual KeyError would always report the empty ``frozenset()`` as the missing
4144 key. Now it correctly refers to the initial element.

Walter Dörwalded960ac2009-05-03 22:36:33 +00004164- Issue #5108: Handle %s like %S and %R in PyUnicode_FromFormatV(): Call
4165 PyUnicode_DecodeUTF8() once, remember the result and output it in a second
4166 step. This avoids problems with counting UTF-8 bytes that ignores the effect
4167 of using the replace error handler in PyUnicode_DecodeUTF8().
4168
Walter Dörwald726ba8e2009-05-06 14:32:35 +00004169- Issue #3739: The unicode-internal encoder now reports the number of characters

Georg Brandlba83f822010-03-14 09:50:54 +00004172- Issue #2422: When compiled with the ``--with-valgrind`` option, the pymalloc

4174 gives improved memory leak detection when running under Valgrind, while taking
4175 advantage of pymalloc at other times.

5399 threads could return successfully while some Thread objects were still
5400 referenced. This also introduces a new private function: ``thread._count()``.

5418 Lib/lib-tk/test/test_tkinter/test_loadtk. With this, these tests demonstrate
Georg Brandlba83f822010-03-14 09:50:54 +00005419 the same behaviour as test_ttkguionly (and now also test_tk) which is to skip
5420 the tests if DISPLAY is defined but can't be used.

Georg Brandlba83f822010-03-14 09:50:54 +00005425- Issue #5354: New test support function import_fresh_module() makes it easy to
5426 import both normal and optimised versions of modules. test_heapq and
5427 test_warnings have been adjusted to use it, tests for other modules with both
5428 C and Python implementations in the stdlib can be adjusted to use it over
5429 time.

Georg Brandlba83f822010-03-14 09:50:54 +00005437- regrtest no longer treats ImportError as equivalent to SkipTest. Imports that
5438 should cause a test to be skipped are now done using import_module from test
5439 support, which does the conversion.

Martin v. Löwis9fa5a282008-09-11 06:53:30 +00005540- Issue #3642: Suppress warning in obmalloc when size_t is larger than uint.
5541
Amaury Forgeot d'Arc05e34492008-09-10 22:04:45 +00005542- Issue #3743: In a few places, PY_FORMAT_SIZE_T was incorrectly used with
5543 PyString_FromFormat or PyErr_Format to display size_t values. The macro
5544 PY_FORMAT_SIZE_T is designed to select the correct format for the OS
5545 ``printf`` function, whereas PyString_FromFormat has an independent
5546 implementation and uses "%zd" on all platforms for size_t values.
5547 This makes a difference on win64, where ``printf`` needs "%Id" to display
5548 64bit values.

Benjamin Peterson97179b02008-09-09 20:55:01 +00005550- Issue #3634: _weakref.ref(Exception).__init__() gave invalid return value on

5554 object; previously an int would be returned for small values. the __long__
5555 method is allowed to return either an int or a long, but the behaviour of
5556 float objects should not change to respect backward compatibility.

Antoine Pitroud4ae97b2008-08-29 18:39:48 +00005565 was correctly parsed but parsing of subsequent arguments failed.
5566
Vinay Sajip35e3b032008-09-01 14:33:59 +00005567- Issue #2534: speed up isinstance() and issubclass() by 50-70%, so as to
Antoine Pitrou0668c622008-08-26 22:42:08 +00005568 match Python 2.5 speed despite the __instancecheck__ / __subclasscheck__
5569 mechanism. In the process, fix a bug where isinstance() and issubclass(),
5570 when given a tuple of classes as second argument, were looking up
5571 __instancecheck__ / __subclasscheck__ on the tuple rather than on each
5572 type object.

5669
Amaury Forgeot d'Arc293924b2008-09-02 23:19:56 +00005670- Issue #2975: When compiling several extension modules with Visual Studio 2008
5671 from the same python interpreter, some environment variables would grow
5672 without limit.
5673
Benjamin Peterson37346b22008-08-23 20:27:43 +00005674- Issue #3643: Added a few more checks to _testcapi to prevent segfaults by
5675 exploitation of poor argument checking.
5676
Gerhard Häringef2276b2008-09-12 13:54:06 +00005677- sqlite3: Changed docstring of iterdump() to mark method as "Non-standard".

5690 wrapper for warnings.catch_warnings() that makes it easier to check
5691 that expected warning messages are being reported.
5692

Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00005711What's New in Python 2.6 beta 3?
5712================================
5713
Barry Warsaw07a4a382008-08-21 01:15:08 +00005714*Release date: 20-Aug-2008*
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00005715
5716Core and Builtins
5717-----------------
5718
Guido van Rossumf8402962008-08-20 15:01:50 +00005719- Issue #1878: Remove Py_TPFLAGS_HAVE_VERSION_TAG from
5720 Py_TPFLAGS_DEFAULT when not building the core. This means 3rd party
5721 extensions do not automatically benefit from the class attribute
5722 cache; they will have to explicitly add Py_TPFLAGS_HAVE_VERSION_TAG
5723 to their tp_flags field if they care. This is a backwards
5724 compatibility feature; in 3.0, all types will use the cache by
5725 default.
5726
Benjamin Petersonf647dc12008-08-20 01:27:30 +00005727- Keyword arguments can now follow starred arguments. (``f(a, *args,
5728 keyword=23)`` is now valid syntax.)
5729
Thomas Heller0ad5ae02008-08-19 19:25:04 +00005730- ctypes function pointers that are COM methods have a boolean True
5731 value again.
5732
Martin v. Löwisf91d46a2008-08-12 14:49:50 +00005733- Issue #3139: Make buffer-interface thread-safe wrt. PyArg_ParseTuple,
5734 by denying s# to parse objects that have a releasebuffer procedure,
5735 and introducing s*.
5736
Georg Brandl1e13ea92008-08-11 09:07:59 +00005737- Issue #3537: Fix an assertion failure when an empty but presized dict
5738 object was stored in the freelist.
5739
Mark Dickinsonb6467572008-08-04 21:30:09 +00005740- Issue #1481296: Make long(float('nan')) and int(float('nan')) raise
5741 ValueError consistently across platforms.
5742
Amaury Forgeot d'Arc39fd6722008-07-31 21:28:03 +00005743- Issue #3479: On platforms where sizeof(int) is smaller than sizeof(long)
5744 (64bit Unix, for example), unichr() would truncate its argument and return
5745 u'\x00' for unichr(2**32). Now it properly raises an OverflowError.
5746
Neal Norwitze7d8be82008-07-31 17:17:14 +00005747- Apply security patches from Apple.
5748
Amaury Forgeot d'Arc246daed2008-07-31 00:42:16 +00005749- Issue #2542: Now that issubclass() may call arbitrary code, ensure that
5750 PyErr_ExceptionMatches returns 0 when an exception occurs there.
5751
Antoine Pitrou92f82162008-07-25 22:22:08 +00005752- Issue #1819: function calls with several named parameters are now on
5753 average 35% faster (as measured by pybench).
5754
Amaury Forgeot d'Arce4921fe2008-07-21 22:00:38 +00005755- Issue #2378: An unexpected UnboundLocalError or NameError could appear when
5756 the python debugger steps into a class statement: the free variables (local
5757 variables defined in an outer scope) would be deleted from the outer scope.
5758
Gregory P. Smith0470bab2008-07-22 04:46:32 +00005759- Issue #2620: Overflow checking when allocating or reallocating memory
5760 was not always being done properly in some python types and extension
5761 modules. PyMem_MALLOC, PyMem_REALLOC, PyMem_NEW and PyMem_RESIZE have
5762 all been updated to perform better checks and places in the code that
5763 would previously leak memory on the error path when such an allocation
5764 failed have been fixed.
5765
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00005766Library
5767-------
5768
Hirokazu Yamamoto838c79f2008-08-20 13:14:07 +00005769- Issue #3612: Added some missing basic types in ctypes.wintypes.
5770
Benjamin Petersone977ad42008-08-20 01:42:01 +00005771- The methods ``is_in_tuple()``, ``is_vararg()``, and ``is_keywordarg()`` of
5772 symtable.Symbol have been deprecated for removal in 3.0 and the next release.
5773
Amaury Forgeot d'Arc351ffb82008-08-18 19:23:47 +00005774- Issue #2234: distutils failed for some versions of the cygwin compiler. The
5775 version reported by these tools does not necessarily follow the python
5776 version numbering scheme, so the module is less strict when parsing it.
5777
Nick Coghlanf70385a2008-08-18 12:42:46 +00005778- Issue #2235: Added Py3k warnings for types which will become unhashable
5779 under the stricter __hash__ inheritance rules in 3.0. Several types
5780 which did not meet the rules for hash invariants and were already
5781 unhashable in 3.0 have now been explicitly flagged as unhashable in
5782 2.6 as well (collections.Mapping, collections.Set, unittest.TestSuite,
5783 xml.dom.minidom.NamedNodeMap, numbers.Number, UserList.UserList)
5784
Brett Cannon88f801d2008-08-18 00:46:22 +00005785- Update __all__ for cookielib, csv, os, urllib2, and weakref to include things
5786 imported into the module but exposed as part of the module's API.
5787
Brett Cannon7b96f072008-08-18 00:41:11 +00005788- Remove an unneeded import of abc.ABCMeta from 'inspect'.
5789
Brett Cannon46225e72008-08-18 00:36:52 +00005790- Remove unneeded imports of 'sys' and 'warnings' from 'io'.
5791
Brett Cannon25c9d6a2008-08-17 22:10:11 +00005792- Remove unneeded imports of 'warnings' from shelve, filecmp, and dummy_thread.
5793
Hirokazu Yamamoto41a81eb2008-08-17 13:10:46 +00005794- Issue #3575: Incremental decoder's decode function now takes bytearray
5795 by using 's*' instead of 't#'.
5796
Mark Dickinson3e4caeb2009-02-21 20:27:01 +00005797- Issue #2222: Fixed reference leak when occurred os.rename()
Hirokazu Yamamoto7f30a682008-08-17 09:46:56 +00005798 fails unicode conversion on 2nd parameter. (windows only)
5799
Georg Brandl222e2082010-08-01 22:27:39 +00005800- Issue #2464: urllib2 now supports a malformation in the URL received
Facundo Batista94f243a2008-08-17 03:38:39 +00005801 in a redirect.
5802
Brett Cannonabe423e2008-08-16 21:47:07 +00005803- Silence the DeprecationWarning raised when importing mimetools in
Brett Cannon721b1452008-08-16 22:00:27 +00005804 BaseHTTPServer, cgi (and rfc822), httplib.
Brett Cannonabe423e2008-08-16 21:47:07 +00005805
Facundo Batistaeb90b782008-08-16 14:44:07 +00005806- Issue #2776: fixed small issue when handling an URL with double slash
5807 after a 302 response in the case of not going through a proxy.
5808
Antoine Pitroub90a8be2008-08-15 21:03:21 +00005809- Issue #2676: in the email package, content-type parsing was hanging on
5810 pathological input because of quadratic or exponential behaviour of a
5811 regular expression.
5812
Antoine Pitrou11ec65d2008-08-14 21:04:30 +00005813- Issue #3476: binary buffered reading through the new "io" library is now
5814 thread-safe.
5815
Brett Cannonbf3157b2008-08-14 05:00:03 +00005816- Silence the DeprecationWarning of rfc822 when it is imported by mimetools
5817 since mimetools itself is deprecated. Because modules are cached, all
5818 subsequent imports of rfc822 will not raise a visible DeprecationWarning.
5819
Antoine Pitrou9fcd4b32008-08-11 17:21:36 +00005820- Issue #3134: shutil referenced undefined WindowsError symbol.
5821
Robert Schuppenies14646332008-08-10 11:01:53 +00005822- Issue #1342811: Fix leak in Tkinter.Menu.delete. Commands associated to
5823 menu entries were not deleted.
5824
Brett Cannon83e81842008-08-09 23:30:55 +00005825- Copied the implementation of reduce() to _functools.reduce() to have a
5826 version that did not raise a DeprecationWarning under -3.
5827
Antoine Pitrou76b8bee2008-08-09 17:27:23 +00005828- Issue #3205: When iterating over a BZ2File fails allocating memory, raise
5829 a MemoryError rather than silently stop the iteration.
5830
Guido van Rossum59ce9012008-08-09 14:55:34 +00005831- Issue #3487: sre "bytecode" validator. Passing invalid "re-bytecode"
5832 to _sre.compile() will now be rejected. This should not affect anybody
5833 since the re.compile() function never generates invalid re-bytecode.
5834
Skip Montanaroa032bf42008-08-08 22:52:51 +00005835- Issue #3436: Make csv.DictReader's fieldnames attribute a property so that
5836 upon first access it can be automatically initialized from the csv file if
5837 it wasn't initialized during instantiation.
5838
Brett Cannon3aa2a492008-08-06 22:28:09 +00005839- Issue #2338: Create imp.reload() to help with transitioning to Python 3.0 as
5840 the reload() built-in has been removed.
5841
Brett Cannon7e30b672008-08-04 21:52:25 +00005842- Changed code in the following modules/packages to remove warnings raised
Brett Cannonc1b76e42008-08-09 23:06:16 +00005843 while running under the ``-3`` flag: aifc, asynchat, asyncore, bdb, bsddb,
Brett Cannon047e4a92008-08-17 04:16:04 +00005844 ConfigParser, cookielib, csv, difflib, distutils, DocXMLRPCServer, email,
5845 filecmp, fileinput, inspect, logging, modulefinder, pdb, pickle, profile,
5846 pstats, pydoc, re, rlcompleter, SimpleXMLRPCServer, shelve, socket,
5847 subprocess, sqlite3, tarfile, Tkinter, test.test_support, textwrap,
5848 threading, tokenize, traceback, urlparse, wsgiref, xml, xmlrpclib.
Brett Cannon7e30b672008-08-04 21:52:25 +00005849
Lars Gustäbel727bd0b2008-08-02 11:26:39 +00005850- Issue #3039: Fix tarfile.TarFileCompat.writestr() which always
5851 raised an AttributeError.
5852
Benjamin Peterson01a24322008-07-28 23:35:27 +00005853- Issue #2523: Fix quadratic behaviour when read()ing a binary file without
Antoine Pitroude781a42008-08-09 12:43:23 +00005854 asking for a specific length. This problem only affected files opened
5855 using the new "io" module, not the built-in open() function.
Benjamin Peterson01a24322008-07-28 23:35:27 +00005856
Mark Dickinsonfe84cce2008-07-27 06:39:07 +00005857- Issue #3449: Update decimal module to use most recent specification
5858 (v. 1.68) and tests (v. 2.58) from IBM.
5859
Georg Brandl222e2082010-08-01 22:27:39 +00005860- Issue #3437: Bug fix in robotparser parsing of Allow: lines.
Skip Montanarof9ac43f2008-07-27 00:50:41 +00005861

5864
Georg Brandlf9efabb2008-07-23 15:16:45 +00005865- Deprecate the "ast" parser function aliases.
5866
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00005867- Issue #3120: On 64-bit Windows the subprocess module was truncating handles.
5868
5869- Issue #3303: Fix a crash in locale.strcoll() when calling it with
5870 invalid arguments.
5871
5872- Issue #3302: Fix several crashes when calling locale's gettext functions
5873 with None arguments.
5874
5875- Issue #3389: Allow resolving dotted names for handlers in logging
5876 configuration files.
5877

5879
Antoine Pitrou5fdfa3e2008-07-25 19:42:26 +00005880- Issue #3394: zipfile.writestr sets external attributes when passed a
5881 file name rather than a ZipInfo instance, so files are extracted with
5882 mode 0600 rather than 000 under Unix.
5883
Gregory P. Smitha36f8fe2008-08-04 00:13:29 +00005884- Issue #1857: subprocess.Popen.poll gained an additional _deadstate keyword
5885 argument in python 2.5, this broke code that subclassed Popen to include its
5886 own poll method. Fixed my moving _deadstate to an _internal_poll method.

5894-------------
5895
Nick Coghlan6e8fef02008-08-18 13:14:22 +00005896- Issue #2235: the C API function PyObject_HashNotImplemented and its
5897 interaction with the tp_hash slot (added in 2.6b2) are now documented
5898
Nick Coghlan2a0c2b12008-08-04 12:47:17 +00005899- Issue #643841: The language reference now provides more detailed
5900 coverage of the lookup process for special methods. The disclaimers
5901 regarding lack of coverage of new-style classes have also been
5902 removed, since the coverage is now fairly reasonable.

Raymond Hettingere3ae6552008-06-20 04:18:15 +00005905What's New in Python 2.6 beta 2?
5906================================
5907
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00005908*Release date: 17-Jul-2008*
5909
Raymond Hettingere3ae6552008-06-20 04:18:15 +00005910Core and Builtins
5911-----------------
5912
Georg Brandl3e483f62008-07-16 22:57:41 +00005913- Issue #3156: Fix inconsistent behavior of the bytearray type: all
5914 its methods now allow for items objects that can be converted to
5915 an integer using operator.index().
5916
Mark Dickinson64b7e502008-07-16 09:40:03 +00005917- Issue #3360: Fix incorrect parsing of '020000000000.0', which
5918 produced a ValueError instead of giving the correct float.
5919
Eric Smitha5fa5a22008-07-16 00:11:49 +00005920- Issue #3083: Add alternate (#) formatting for bin, oct, hex output
5921 for str.format(). This adds the prefix 0b, 0o, or 0x, respectively.
5922
Mark Dickinson7103aa42008-07-15 19:08:33 +00005923- Issue #3008: the float type has a new instance method 'float.hex'
5924 and a new class method 'float.fromhex' to convert floating-point
5925 numbers to and from hexadecimal strings, respectively.
5926
Nick Coghlan6d6bd442008-07-15 15:40:22 +00005927- Issue #2235: __hash__ is once again inherited by default. To allow
5928 collections.Hashable to remain meaningful in the presence of the
5929 default hash implementation (object.__hash__), it is now possible
5930 to explicit block inheritance of hash by setting __hash__=None at
5931 the Python level, or tp_hash=PyObject_HashNotImplemented at the C
5932 level.
5933
Nick Coghlanb028f502008-07-13 14:52:36 +00005934- Issue #3221: Issue a RuntimeWarning instead of raising SystemError if
5935 the parent module cannot be found while performing an absolute import.
5936 This means that an incorrectly defined __package__ attribute will
5937 now only prevent relative imports in that module rather than causing
5938 all imports from that module to fail.
5939
Nick Coghlan14ff9942008-07-08 14:21:42 +00005940- Issue #2517: Allow unicode messages in Exceptions again by correctly
5941 bypassing the instance dictionary when looking up __unicode__ on
5942 new-style classes.
5943
Amaury Forgeot d'Arcbdd941f2008-07-01 20:38:04 +00005944- Issue #3242: Fix a crash inside the print statement, if sys.stdout is
5945 set to a custom object whose write() method happens to install
5946 another file in sys.stdout.
5947
Amaury Forgeot d'Arc1f40c8a2008-06-30 22:42:40 +00005948- Issue #3088: Corrected a race condition in classes derived from
5949 threading.local: the first member set by a thread could be saved in
5950 another thread's dictionary.
5951
Mark Dickinson1ec2fcd2008-06-20 14:53:43 +00005952- Issue #3004: Minor change to slice.indices(): the start and stop
5953 arguments are now treated identically, making the behaviour easier
5954 to describe and understand. For example, slice(None, -10,
5955 1).indices(9) now returns (0, 0, 1) instead of (0, -1, 1), and
5956 slice(None, 10, -1).indices(10) returns (9, 9, -1) instead of (9,
5957 10, -1).

6408

6410 mode or even as a 4-way universal binary (that is, PPC, i386,
Georg Brandl5cc774e2008-06-11 20:28:06 +00006411 PPC64 and x86_64 support in one binary).
Ronald Oussoren5640ce22008-06-05 12:58:24 +00006412
6413 This is controlled by the configure argument ``--with-universal-archs``:
6414
6415 - ``--with-universal-archs=all``: install 4-way universal
6416
6417 - ``--with-universal-archs=32-bit``: install 2-way universal, 32-bit (the default)
6418
6419 - ``--with-universal-archs=64-bit``: install 2-way universal, 64-bit
6420

6460 two handlers that derive the same default base class.
Amaury Forgeot d'Arc96865852008-04-22 21:14:41 +00006461
Christian Heimese74c8f22008-04-19 02:23:57 +00006462- Added kill, terminate and send_signal(sig) to subprocess.Popen.
6463

Georg Brandl3ee81df2008-05-17 18:14:43 +00006473- Issue #1631171: Re-implement the 'warnings' module in C (the
6474 original Python code has been kept as backup). This will allow for
6475 using the 'warning's machinery in such places as the parser where
6476 use of pure Python code is not possible. Both the ``showarning()``
6477 and ``formatwarning()`` gain an optional 'line' argument which is
6478 not called by default for backwards-compatibility reasons. Setting
6479 ``warnings.showwarning()`` to an implementation that lacks support
6480 for the ``line`` argument will raise a DeprecationWarning.

6504
Gregory P. Smithd59fefb2008-04-22 08:11:33 +00006505- The getpass module has been improved on Unix. It now uses /dev/tty

Georg Brandl3ee81df2008-05-17 18:14:43 +00006543- Issue #2550: The approach used by client/server code for obtaining
6544 ports to listen on in network-oriented tests has been refined in an
6545 effort to facilitate running multiple instances of the entire
6546 regression test suite in parallel without issue.
6547 test_support.bind_port() has been fixed such that it will always
6548 return a unique port -- which wasn't always the case with the
6549 previous implementation, especially if socket options had been set
6550 that affected address reuse (i.e. SO_REUSEADDR, SO_REUSEPORT). The
6551 new implementation of bind_port() will actually raise an exception
6552 if it is passed an AF_INET/SOCK_STREAM socket with either the
6553 SO_REUSEADDR or SO_REUSEPORT socket option set. Furthermore, if
6554 available, bind_port() will set the SO_EXCLUSIVEADDRUSE option on
6555 the socket it's been passed. This currently only applies to
6556 Windows. This option prevents any other sockets from binding to the
6557 host/port we've bound to, thus removing the possibility of the
6558 'non-deterministic' behaviour, as Microsoft puts it, that occurs
6559 when a second SOCK_STREAM socket binds and accepts to a host/port
6560 that's already been bound by another socket. The optional preferred
6561 port parameter to bind_port() has been removed. Under no
6562 circumstances should tests be hard coding ports!
6563
6564 test_support.find_unused_port() has also been introduced, which will
6565 pass a temporary socket object to bind_port() in order to obtain an
6566 unused port. The temporary socket object is then closed and
6567 deleted, and the port is returned. This method should only be used
6568 for obtaining an unused port in order to pass to an external program
6569 (i.e. the -accept [port] argument to openssl's s_server mode) or as
6570 a parameter to a server-oriented class that doesn't give you direct
6571 access to the underlying socket used.
6572
6573 Finally, test_support.HOST has been introduced, which should be used
6574 for the host argument of any relevant socket calls (i.e. bind and
6575 connect).
Trent Nelsone41b0062008-04-08 23:47:30 +00006576
6577 The following tests were updated to following the new conventions:
Georg Brandl3ee81df2008-05-17 18:14:43 +00006578 test_socket, test_smtplib, test_asyncore, test_ssl, test_httplib,
Trent Nelsone41b0062008-04-08 23:47:30 +00006579 test_poplib, test_ftplib, test_telnetlib, test_socketserver,
6580 test_asynchat and test_socket_ssl.
6581
Georg Brandl3ee81df2008-05-17 18:14:43 +00006582 It is now possible for multiple instances of the regression test
6583 suite to run in parallel without issue.

Eric Smitha73fbe72008-02-23 03:09:44 +00006862- Added the future_builtins module, which contains hex() and oct().
6863 These are the PEP 3127 version of these functions, designed to be
6864 compatible with the hex() and oct() builtins from Python 3.0. They
6865 differ slightly in their output formats from the existing, unchanged
6866 Python 2.6 builtins. The expected usage of the future_builtins
6867 module is:
6868 from future_builtins import hex, oct
6869
Eric Smith7ef40bf2008-02-20 23:34:22 +00006870- Issue #1600: Modifed PyOS_ascii_formatd to use at most 2 digit
6871 exponents for exponents with absolute value < 100. Follows C99
6872 standard. This is a change on Windows, which would use 3 digits.
6873 Also, added 'n' to the formats that PyOS_ascii_formatd understands,
6874 so that any alterations it does to the resulting string will be
6875 available in stringlib/formatter.h (for float.__format__).
6876
Eric Smith5a3c1352008-02-19 13:21:56 +00006877- Implemented PEP 3101, Advanced String Formatting. This adds a new
6878 builtin format(); a format() method for str and unicode; a
6879 __format__() method to object, str, unicode, int, long, float, and
6880 datetime; the class string.Formatter; and the C API
6881 PyObject_Format().
6882
Georg Brandl3ee81df2008-05-17 18:14:43 +00006883- Fixed several potential crashes, all caused by specially crafted
6884 __del__ methods exploiting objects in temporarily inconsistent
6885 state.
Amaury Forgeot d'Arc632fad32008-02-16 20:55:24 +00006886
Vinay Sajipb7edfc42008-04-02 21:10:23 +00006887- Issue #2115: Important speedup in setting __slot__ attributes. Also
Georg Brandl3ee81df2008-05-17 18:14:43 +00006888 prevent a possible crash: an Abstract Base Class would try to access
6889 a slot on a registered virtual subclass.

Georg Brandl3ee81df2008-05-17 18:14:43 +00006894- Clear all free lists during a gc.collect() of the highest generation
6895 in order to allow pymalloc to free more arenas. Python may give back
6896 memory to the OS earlier.
Christian Heimes3b718a72008-02-14 12:47:33 +00006897
Georg Brandl3ee81df2008-05-17 18:14:43 +00006898- Issue #2045: Fix an infinite recursion triggered when printing a
6899 subclass of collections.defaultdict, if its default_factory is set
6900 to a bound method.
Amaury Forgeot d'Arcb01aa432008-02-08 00:56:02 +00006901
Christian Heimesf75dbef2008-02-08 00:11:31 +00006902- Fixed a minor memory leak in dictobject.c. The content of the free
6903 list was not freed on interpreter shutdown.
6904
Georg Brandl21e99f42010-03-07 15:23:59 +00006905- Limit free list of method and built-in function objects to 256
Georg Brandl3ee81df2008-05-17 18:14:43 +00006906 entries each.
Christian Heimes6075a822008-02-06 12:44:34 +00006907
Georg Brandl3ee81df2008-05-17 18:14:43 +00006908- Patch #1953: Added ``sys._compact_freelists()`` and the C API
6909 functions ``PyInt_CompactFreeList`` and ``PyFloat_CompactFreeList``
Christian Heimes422051a2008-02-04 18:00:12 +00006910 to compact the internal free lists of pre-allocted ints and floats.
6911
Georg Brandl3ee81df2008-05-17 18:14:43 +00006912- Issue #1983: Fixed return type of fork(), fork1() and forkpty()
6913 calls. Python expected the return type int but the fork familie
6914 returns pi_t.
Christian Heimes951cc0f2008-01-31 23:08:23 +00006915
Georg Brandl3ee81df2008-05-17 18:14:43 +00006916- Issue #1678380: Fix a bug that identifies 0j and -0j when they
6917 appear in the same code unit.
Mark Dickinson105be772008-01-31 22:17:37 +00006918

Georg Brandl3ee81df2008-05-17 18:14:43 +00006928- Patch #1473257: generator objects gain a gi_code attribute. This is
6929 the same object as the func_code attribute of the function that
6930 produced the generator.
Georg Brandl0cdf9a32008-01-26 14:14:20 +00006931
Georg Brandl3ee81df2008-05-17 18:14:43 +00006932- Issue #1920: "while 0" statements were completely removed by the
6933 compiler, even in the presence of an "else" clause, which is
6934 supposed to be run when the condition is false. Now the compiler
6935 correctly emits bytecode for the "else" suite.
Amaury Forgeot d'Arc31eaafe2008-01-24 22:59:25 +00006936
Guido van Rossumeead05f2008-01-24 18:21:02 +00006937- A few crashers fixed: weakref_in_del.py (issue #1377858);
6938 loosing_dict_ref.py (issue #1303614, test67.py);
6939 borrowed_ref_[34].py (not in tracker).
6940
Vinay Sajipd7cf32e2008-01-24 12:43:33 +00006941- Issue #1069410: The "can't load dll" message box on Windows is
Christian Heimesb2302ba2008-01-23 17:15:06 +00006942 suppressed while an extension is loaded by calling SetErrorMode in
6943 dynload_win.c. The error is still reported properly.
6944
Georg Brandl3ee81df2008-05-17 18:14:43 +00006945- Issue #1915: Python compiles with --enable-unicode=no again. However
Christian Heimes082c9b02008-01-23 14:20:50 +00006946 several extension methods and modules do not work without unicode
6947 support.
6948
Georg Brandl26543b12008-01-21 18:36:51 +00006949- Issue #1882: when compiling code from a string, encoding cookies in the
6950 second line of code were not always recognized correctly.
6951
Georg Brandl14404b62008-01-19 19:27:05 +00006952- Issue #1679: "0x" was taken as a valid integer literal.
6953
Georg Brandl6caad7d2008-01-26 14:19:22 +00006954- Issue #1865: ``bytes`` as an alias for ``str`` and b"" as an alias "" were
Christian Heimes288e89a2008-01-18 18:24:07 +00006955 added.
6956
Christian Heimesc94e2b52008-01-14 04:13:37 +00006957- sys.float_info / PyFloat_GetInfo: The floating point information
6958 object was converted from a dict to a specialized structseq object.
6959
Georg Brandl3ee81df2008-05-17 18:14:43 +00006960- Patch #1816: Added sys.flags structseq. It exposes the status of
6961 most command line arguments and PYTHON* environment variables.
Christian Heimesf31b69f2008-01-14 03:42:48 +00006962
Georg Brandl3ee81df2008-05-17 18:14:43 +00006963- Objects/structseq.c: Implemented new structseq representation. The

6965 readable.
Christian Heimes9c201962008-01-14 03:33:52 +00006966
Georg Brandl3ee81df2008-05-17 18:14:43 +00006967- Patch #1700288: added a type attribute cache that caches method

Georg Brandl3ee81df2008-05-17 18:14:43 +00007024- Patch #1739468: Directories and zipfiles containing a __main__.py
7025 file can now be directly executed by passing their name to the
7026 interpreter. The directory/zipfile is automatically inserted as the
7027 first entry in sys.path.

Georg Brandl3ee81df2008-05-17 18:14:43 +00007029- Issue #1265: Fix a problem with sys.settrace, if the tracing
7030 function uses a generator expression when at the same time the
7031 executed code is closing a paused generator.
Amaury Forgeot d'Arc0d75f092007-11-13 21:54:28 +00007032
Raymond Hettinger1760c8a2007-11-08 02:52:43 +00007033- sets and frozensets now have an isdisjoint() method.

7038
Georg Brandl21e99f42010-03-07 15:23:59 +00007039- The enumerate() built-in function is no longer bounded to sequences
Georg Brandl3ee81df2008-05-17 18:14:43 +00007040 smaller than LONG_MAX. Formerly, it raised an OverflowError. Now,
7041 automatically shifts from ints to longs.
Raymond Hettinger8f669372007-10-03 21:18:11 +00007042
Georg Brandl3ee81df2008-05-17 18:14:43 +00007043- Issue #1686386: Tuple's tp_repr did not take into account the
7044 possibility of having a self-referential tuple, which is possible
7045 from C code. Nor did object's tp_str consider that a type's tp_str
7046 could do something that could lead to an inifinite recursion.
7047 Py_ReprEnter() and Py_EnterRecursiveCall(), respectively, fixed the
7048 issues.
Brett Cannon0b14f242007-09-30 19:45:10 +00007049
Georg Brandl3ee81df2008-05-17 18:14:43 +00007050- Issue #1164: It was possible to trigger deadlock when using the
7051 'print' statement to write to a file since the GIL was not released
7052 as needed. Now PyObject_Print() does the right thing along with
7053 various tp_print implementations of the built-in types and those in
7054 the collections module.
Brett Cannon01531592007-09-17 03:28:34 +00007055
Georg Brandl3ee81df2008-05-17 18:14:43 +00007056- Issue #1147: Exceptions were directly allowing string exceptions in

7058 allowed.

Brett Cannona0c05512007-09-10 21:38:27 +00007062
Brett Cannon1e534b52007-09-07 04:18:30 +00007063- Issue #1202533: Fix infinite recursion calls triggered by calls to
Georg Brandl3ee81df2008-05-17 18:14:43 +00007064 PyObject_Call() never calling back out to Python code to trigger
7065 recursion depth updates/checks. Required the creation of a static
7066 RuntimeError instance in case normalizing an exception put the
7067 recursion check value past its limit. Fixes crashers
7068 infinite_rec_(1|2|4|5).py.

Neal Norwitz0ac60192007-05-27 04:08:54 +00007083- Add new attribute names for function objects. All the func_* become
Georg Brandl3ee81df2008-05-17 18:14:43 +00007084 __*__ attributes. (Some already existed, e.g., __doc__ and
7085 __name__.)
Neal Norwitz0ac60192007-05-27 04:08:54 +00007086
Neal Norwitz8b2bfbc2007-05-23 06:35:32 +00007087- Add -3 option to the interpreter to warn about features that are
7088 deprecated and will be changed/removed in Python 3.0.
7089
Georg Brandl2134e752007-05-21 20:34:16 +00007090- Patch #1686487: you can now pass any mapping after '**' in function
7091 calls.
7092
Collin Winter62903052007-05-18 23:11:24 +00007093- except clauses may now be spelled either "except E, target:" or
Georg Brandl3ee81df2008-05-17 18:14:43 +00007094 "except E as target:". This is to provide forwards compatibility
7095 with Python 3.0.

Vinay Sajip8549ce32007-05-06 17:53:37 +00007102- When __slots__ are set to a unicode string, make it work the same as
Neal Norwitzcbd9ee62007-04-14 05:25:50 +00007103 setting a plain string, ie don't expand to single letter identifiers.
7104
Raymond Hettinger13936692007-04-11 18:40:58 +00007105- Request #1191699: Slices can now be pickled.
7106
Raymond Hettinger4db5fe92007-04-12 04:10:00 +00007107- Request #1193128: str.translate() now allows a None argument for
7108 translations that only remove characters without re-mapping the
7109 remaining characters.
7110
Georg Brandl5cb76c12007-03-21 09:00:39 +00007111- Patch #1682205: a TypeError while unpacking an iterable is no longer

7115
Guido van Rossum143b5642007-03-23 04:58:42 +00007116- Bug #1683368: The object.__init__() and object.__new__() methods are
7117 now stricter in rejecting excess arguments. The only time when
7118 either allows excess arguments is when it is not overridden and the
7119 other one is. For backwards compatibility, when both are
7120 overridden, it is a deprecation warning (for now; maybe a Py3k
Guido van Rossum234b1ff2007-03-23 19:39:01 +00007121 warning later). Also, type.__init__() insists on the same signature
7122 as supported by type.__new__().
Guido van Rossum143b5642007-03-23 04:58:42 +00007123
Georg Brandl3ee81df2008-05-17 18:14:43 +00007124- Patch #1675423: PyComplex_AsCComplex() now tries to convert an
7125 object to complex using its __complex__() method before falling back
7126 to the __float__() method. Therefore, the functions in the cmath
7127 module now can operate on objects that define a __complex__()
7128 method.
Georg Brandl2b869942007-03-17 16:08:45 +00007129
Georg Brandl3ee81df2008-05-17 18:14:43 +00007130- Patch #1623563: allow __class__ assignment for classes with

7132 same slot names.

7139 its type.

7145
Georg Brandl7b9c5552007-03-12 14:30:05 +00007146- Bug #1678647: write a newline after printing an exception in any
7147 case, even when converting the value to a string failed.
7148
Georg Brandl871f1bc2007-03-12 13:17:36 +00007149- The dir() function has been extended to call the __dir__() method on
Georg Brandl3ee81df2008-05-17 18:14:43 +00007150 its argument, if it exists. If not, it will work like before. This
7151 allows customizing the output of dir() in the presence of a
7152 __getattr__().

Georg Brandl3ee81df2008-05-17 18:14:43 +00007160- Patch #1491866: change the complex() constructor to allow
7161 parthensized forms. This means complex(repr(x)) now works instead of
7162 raising a ValueError.
Collin Wintere38051d2007-03-09 20:33:07 +00007163
Georg Brandlaa2321b2007-03-07 00:40:28 +00007164- Patch #703779: unset __file__ in __main__ after running a file. This
Georg Brandl3ee81df2008-05-17 18:14:43 +00007165 makes the filenames the warning module prints much more sensible
7166 when a PYTHONSTARTUP file is used.
Georg Brandlaa2321b2007-03-07 00:40:28 +00007167

Georg Brandl0fca97a2007-03-05 22:28:08 +00007179- Patch #1674228: when assigning a slice (old-style), check for the
7180 sq_ass_slice instead of the sq_slice slot.
7181
Georg Brandl3ee81df2008-05-17 18:14:43 +00007182- When printing an unraisable error, don't print exceptions. before
7183 the name. This duplicates the behavior whening normally printing
7184 exceptions.

Georg Brandl92a6bae2007-03-13 17:43:32 +00007751- Patch #1603688: ConfigParser.SafeConfigParser now checks values that
Georg Brandl3ee81df2008-05-17 18:14:43 +00007752 are set for invalid interpolation sequences that would lead to

7809 TestCase and TestSuite subclasses (not instances) are no longer
7810 accepted in TestSuite.addTest(). This should cause no

7812 -- the failure just occurred later, with a more cumbersome
7813 exception.

Georg Brandl3ee81df2008-05-17 18:14:43 +00008094- Issue #829951: In the smtplib module, SMTP.starttls() now complies
8095 with RFC 3207 and forgets any knowledge obtained from the server not
8096 obtained from the TLS negotiation itself. Patch contributed by Bill
8097 Fenner.
Gregory P. Smith2b3ba582008-01-17 08:03:17 +00008098
Georg Brandl3ee81df2008-05-17 18:14:43 +00008099- Issue #1339: The smtplib.SMTP class has been refactored a bit such
Gregory P. Smithbde4ae42008-01-17 08:35:49 +00008100 that the SMTP.starttls() caller no longer needs to call ehlo()
8101 beforehand. SMTP.starttls() now raises an exception of the server
Georg Brandl3ee81df2008-05-17 18:14:43 +00008102 does not claim to support starttls. Adds the
8103 SMTP.ehlo_or_helo_if_needed() method. Patch contributed by Bill

Georg Brandl3ee81df2008-05-17 18:14:43 +00008158- itertools.chain() now has an alternate constructor,

8184 complex, tuple, list, dict, set, and frozenset. Formerly, it would
8185 silently miscode subclasses of those types. Now, it raises a

Raymond Hettinger12e94202007-11-07 01:13:09 +00008187

Georg Brandl3ee81df2008-05-17 18:14:43 +00008202 time so that opening a database previously created with the DB_DUP
8203 or DB_DUPSORT flag set will keep the proper behavior on subsequent
8204 opens. Specifically: dictionary assignment to a DB object will
8205 replace all values for a given key when the database allows
8206 duplicate values. DB users should use DB.put(k, v) when they want
8207 to store duplicates; not DB[k] = v.
Gregory P. Smithec10a4a2007-11-05 02:32:26 +00008208

8214 characters with ASCII value less than 32. Also, it correctly quotes
8215 dots only if they occur on a single line, as opposed to the previous
8216 behavior of quoting dots if they are the second character of any
8217 line.
Georg Brandl4aef7272007-03-13 22:49:43 +00008218

Guido van Rossum7c862f82007-12-13 20:50:10 +00008480- Bug #1608: use -fwrapv when GCC supports it. This is important,
8481 newer GCC versions may optimize away overflow buffer overflow checks
8482 without this option!
8483
Martin v. Löwis63bf1492007-11-12 05:14:05 +00008484- Patch #1418: Make the AC_REPLACE_FUNCS object files actually work.
8485
Raymond Hettingerdc1d1ba2007-11-07 02:45:46 +00008486- Add a FAST_LOOPS build option that speeds-up looping by trading away
Georg Brandl3ee81df2008-05-17 18:14:43 +00008487 periodic threadstate and signal checking in tight loops. By
8488 default, this option is turned-off. It should only be enabled in
8489 debugged, performance critical applications.

8505 returned by python-config if Python was built with --enable-shared
8506 because that prevented the shared library from being used.
8507

8540-----
8541
Georg Brandl3ee81df2008-05-17 18:14:43 +00008542- Unified naming convention for free lists and their limits. All free
8543 lists in Object/ are named ``free_list``, the counter ``numfree``
8544 and the upper limit is a macro ``PyName_MAXFREELIST`` inside an
8545 #ifndef block.
Christian Heimes5b970ad2008-02-06 13:33:44 +00008546
Georg Brandl3ee81df2008-05-17 18:14:43 +00008547- ``PySet_Add()`` can now modify a newly created frozenset. Similarly
8548 to ``PyTuple_SetItem``, it can be used to populate a brand new
8549 frozenset; but it does not steal a reference to the added item.
Amaury Forgeot d'Arccab3d982008-02-03 22:51:43 +00008550
Vinay Sajipb7edfc42008-04-02 21:10:23 +00008551- Added ``PySet_Check()`` and ``PyFrozenSet_Check()`` to the set API.

8558
8559- Issue #1534: Added ``PyFloat_GetMax()``, ``PyFloat_GetMin()`` and
8560 ``PyFloat_GetInfo()`` to the float API.
8561
Georg Brandl3ee81df2008-05-17 18:14:43 +00008562- Issue #1521: On 64bit platforms, using PyArgs_ParseTuple with the t#
8563 of w# format code incorrectly truncated the length to an int, even
8564 when PY_SSIZE_T_CLEAN is set. The str.decode method used to return
8565 incorrect results with huge strings.
Georg Brandl6caad7d2008-01-26 14:19:22 +00008566
Georg Brandl3ee81df2008-05-17 18:14:43 +00008567- Issue #1629: Renamed Py_Size, Py_Type and Py_Refcnt to Py_SIZE,

8585- Fix some leftovers from the conversion from int to Py_ssize_t
8586 (relevant to strings and sequences of more than 2**31 items).
8587
8588- Make _PyGILState_NoteThreadState() static, it was not used anywhere
8589 outside of pystate.c and should not be necessary.
8590
Georg Brandl3ee81df2008-05-17 18:14:43 +00008591- ``PyImport_Import`` and ``PyImport_ImportModule`` now always do
8592 absolute imports. In earlier versions they might have used relative
8593 imports under some conditions.
Christian Heimes000a0742008-01-03 22:16:32 +00008594
Georg Brandl3ee81df2008-05-17 18:14:43 +00008595- Added case insensitive comparison methods ``PyOS_stricmp(char*,
8596 char*)`` and ``PyOS_strnicmp(char*, char*, Py_ssize_t)``.
Christian Heimes000a0742008-01-03 22:16:32 +00008597
Georg Brandl3ee81df2008-05-17 18:14:43 +00008598- Bug #1542693: remove semi-colon at end of PyImport_ImportModuleEx

8606 requires Windows 2000 or greater. The _WINVER and NTDDI_VERSION
8607 macros are set to Win2k for x86/32bit builds and WinXP for AMD64
8608 builds.
Christian Heimes95d64472008-02-09 19:55:22 +00008609

Georg Brandl3ee81df2008-05-17 18:14:43 +00008623- Removed the macfs module. It had been deprecated since Python 2.5.
8624 This lead to the deprecation of macostools.touched() as it relied
8625 solely on macfs and was a no-op under OS X.
