Ned Deilyc47a4592012-02-11 20:40:24 +0100802 has left two versions of customize_compiler, the original in
803 distutils.sysconfig and another copy in distutils.ccompiler, with some

Ned Deily0d0ea482012-02-10 12:59:06 +0100808- Issue #13590: On OS X 10.7 and 10.6 with Xcode 4.2, building
809 Distutils-based packages with C extension modules may fail because
810 Apple has removed gcc-4.2, the version used to build python.org
811 64-bit/32-bit Pythons. If the user does not explicitly override
812 the default C compiler by setting the CC environment variable,
813 Distutils will now attempt to compile extension modules with clang
814 if gcc-4.2 is required but not found. Also as a convenience, if
815 the user does explicitly set CC, substitute its value as the default
816 compiler in the Distutils LDSHARED configuration variable for OS X.
817 (Note, the python.org 32-bit-only Pythons use gcc-4.0 and the 10.4u
818 SDK, neither of which are available in Xcode 4. This change does not
819 attempt to override settings to support their use with Xcode 4.)

952 arguments with the system default encoding just like the write() method

Lars Gustäbel8babfdf2011-09-05 17:04:18 +0200996- Issue #12841: tarfile unnecessarily checked the existence of numerical user

1091
Ned Deily87e82bb2011-06-28 19:52:59 -07001092- Issue #9516: On Mac OS X, change Distutils to no longer globally attempt to
1093 check or set the MACOSX_DEPLOYMENT_TARGET environment variable for the
1094 interpreter process. This could cause failures in non-Distutils subprocesses
1095 and was unreliable since tests or user programs could modify the interpreter
1096 environment after Distutils set it. Instead, have Distutils set the the
1097 deployment target only in the environment of each build subprocess. It is
1098 still possible to globally override the default by setting
1099 MACOSX_DEPLOYMENT_TARGET before launching the interpreter; its value must be
1100 greater or equal to the default value, the value with which the interpreter
1101 was built.

Barry Warsawc5643282011-07-19 17:06:30 -04001129- sys.setcheckinterval() now updates the current ticker count as well as
1130 updating the check interval, so if the user decreases the check interval,
1131 the ticker doesn't have to wind down to zero from the old starting point
1132 before the new interval takes effect. And if the user increases the
1133 interval, it makes sure the new limit takes effect right away rather have an
1134 early task switch before recognizing the new interval.

2075 by Andrew Bennetts.

2084
Raymond Hettinger20397532010-09-12 02:11:45 +00002085- Issue #9825: removed __del__ from the definition of collections.OrderedDict.
2086 This prevents user-created self-referencing ordered dictionaries from
2087 becoming permanently uncollectable GC garbage. The downside is that
2088 removing __del__ means that the internal doubly-linked list has to wait for
2089 GC collection rather than freeing memory immediately when the refcnt drops
2090 to zero.
2091

2097 would swallow the exception and raise a new one, making it impossible
2098 to fetch the original errno, or to filter timeout errors. Now the
2099 original error is re-raised.

2109 ConfigParser.write.
2110
Daniel Stutzbach66c981b2010-08-31 20:29:39 +00002111- Issue #808164: Fixed socket.close to avoid references to globals, to
2112 avoid issues when socket.close is called from a __del__ method.
2113

2115 can be set to False to turn off the previously undocumented 'popularity'
2116 heuristic. Patch by Terry Reedy and Eli Bendersky
2117
Senthil Kumaran7e8fd5e2010-08-26 06:20:13 +00002118- Issue #8797: urllib2 does a retry for Basic Authentication failure instead of
2119 falling into recursion.
2120
R. David Murray7c4bf552010-08-25 01:45:57 +00002121- Issue #1194222: email.utils.parsedate now returns RFC2822 compliant four
2122 character years even if the message contains RFC822 two character years.
2123
Daniel Stutzbach91287322010-08-24 21:09:30 +00002124- Issue #8750: Fixed MutableSet's methods to correctly handle

2139 ignored by the buffered IO layer anymore.
2140
Benjamin Peterson52c36052010-08-21 03:03:22 +00002141- Issue #2521: Use weakrefs on for caching in the abc module, so that classes

2143
Raymond Hettingera54b2da2010-08-17 19:03:06 +00002144- Issue #9626: the view methods for collections.OrderedDict() were returning

2153 and a BadZipfile error is raised if it doesn't match (as used to be the
2154 case in Python 2.5 and earlier).
2155
Antoine Pitroucb4f47c2010-08-11 13:40:17 +00002156- Issue #9550: a BufferedReader could issue an additional read when the
2157 original read request had been satisfied, which could block indefinitely
2158 when the underlying raw IO channel was e.g. a socket. Report and original
2159 patch by Jason V. Miller.
2160
Fred Drake0a1fa0e2010-08-10 13:09:54 +00002161- Issue #9551: Don't raise TypeError when setting the value to None for

2180 This is how it is supposed to work, wget and curl do the same. Previous

2189 the option character for the added 'h/help' option if prefix_chars
2190 does not contain a '-', instead of raising an error.
2191

2552 E.g.: '\xf1\x80AB'.decode('utf-8', 'replace') now returns u'\ufffdAB' and
2553 replaces with U+FFFD only the start byte ('\xf1') and the continuation byte

2933-----------------
2934
Philip Jenveyaebbaeb2010-04-06 23:24:45 +00002935- Issue #7301: Add environment variable $PYTHONWARNINGS.
2936
Benjamin Peterson3a1dfa22010-04-06 21:50:00 +00002937- Issue #8329: Don't return the same lists from select.select when no fds are
2938 changed.
2939
Georg Brandlfee0f442010-05-22 21:26:21 +00002940- Issue #8259: ``1L << (2**31)`` no longer produces an 'outrageous shift error'
Mark Dickinson82791672010-04-06 16:47:55 +00002941 on 64-bit machines. The shift count for either left or right shift is
2942 permitted to be up to sys.maxsize.
2943
Benjamin Peterson4ceeeb02010-04-03 22:48:51 +00002944- Ensure that tokenization of identifiers is not affected by locale.

Benjamin Peterson1c7c11e2010-04-03 01:28:57 +00002948- Raise a TypeError when trying to delete a T_STRING_INPLACE struct member.
2949
Georg Brandlfee0f442010-05-22 21:26:21 +00002950- Issue #7994: Issue a PendingDeprecationWarning if object.__format__ is called
2951 with a non-empty format string. This is an effort to future-proof user
2952 code. If a derived class does not currently implement __format__ but later
2953 adds its own __format__, it would most likely break user code that had
Antoine Pitrou01a196a2011-01-02 20:05:11 +00002954 supplied a format string. This will be changed to a DeprecationWarning in
Georg Brandlfee0f442010-05-22 21:26:21 +00002955 Python 3.3 and it will be an error in Python 3.4.
Eric Smithd44b2fc2010-04-02 12:30:56 +00002956
Antoine Pitroua57df2c2010-03-31 21:32:15 +00002957- Issue #8268: Old-style classes (not just instances) now support weak

Victor Stinner66644262010-03-10 22:30:19 +00002970- Issue #3137: Don't ignore errors at startup, especially a keyboard interrupt
Georg Brandlba83f822010-03-14 09:50:54 +00002971 (SIGINT). If an error occurs while importing the site module, the error is

2987
Georg Brandlfee0f442010-05-22 21:26:21 +00002988- Issue #8257: The Decimal construct now accepts a float instance directly,
2989 converting that float to a Decimal of equal value:
Mark Dickinson8a950712010-04-03 15:47:46 +00002990
2991 >>> Decimal(1.1)
2992 Decimal('1.100000000000000088817841970012523233890533447265625')
2993
Raymond Hettinger34c35b22010-04-03 10:22:00 +00002994- collections.Counter() now supports a subtract() method.
2995
Georg Brandlfee0f442010-05-22 21:26:21 +00002996- The functools module now has a total_ordering() class decorator to simplify
2997 the specification of rich comparisons.
Raymond Hettingera551f312010-04-04 18:34:45 +00002998
Georg Brandlfee0f442010-05-22 21:26:21 +00002999- The functools module also adds cmp_to_key() as a tool to transition old-style
3000 comparison functions to new-style key-functions.
Raymond Hettingera551f312010-04-04 18:34:45 +00003001
Georg Brandlfee0f442010-05-22 21:26:21 +00003002- Issue #8294: The Fraction constructor now accepts Decimal and float instances
3003 directly.

Georg Brandlfee0f442010-05-22 21:26:21 +00003005- Issue #7279: Comparisons involving a Decimal signaling NaN now signal
3006 InvalidOperation instead of returning False. (Comparisons involving a quiet
3007 NaN are unchanged.) Also, Decimal quiet NaNs are now hashable; Decimal
3008 signaling NaNs remain unhashable.
Mark Dickinsone096e822010-04-02 10:17:07 +00003009
Georg Brandlfee0f442010-05-22 21:26:21 +00003010- Issue #2531: Comparison operations between floats and Decimal instances now
3011 return a result based on the numeric values of the operands; previously they
3012 returned an arbitrary result based on the relative ordering of id(float) and
3013 id(Decimal).
Mark Dickinson99d80962010-04-02 08:53:22 +00003014
Barry Warsawf7f2d6f2010-03-31 21:07:16 +00003015- Issue #8233: When run as a script, py_compile.py optionally takes a single
Georg Brandlfee0f442010-05-22 21:26:21 +00003016 argument `-` which tells it to read files to compile from stdin. Each line is
3017 read on demand and the named file is compiled immediately. (Original patch by
3018 Piotr Ożarowski).

Florent Xicluna58b65662010-03-30 16:29:03 +00003023- Backwards incompatible change: Unicode codepoints line tabulation (0x0B) and
3024 form feed (0x0C) are now considered linebreaks, as specified in Unicode
Georg Brandlfee0f442010-05-22 21:26:21 +00003025 Standard Annex #14. See issue #7643. http://www.unicode.org/reports/tr14/
Florent Xicluna22b24382010-03-30 08:24:06 +00003026
Georg Brandlfee0f442010-05-22 21:26:21 +00003027- Comparisons using one of <, <=, >, >= between a complex instance and a
3028 Fractions instance now raise TypeError instead of returning True/False. This
3029 makes Fraction <=> complex comparisons consistent with int <=> complex, float
3030 <=> complex, and complex <=> complex comparisons.

Mark Dickinson4846a8e2010-04-03 14:05:10 +00003129- Issue #8300: When passing a non-integer argument to struct.pack with any
3130 integer format code, struct.pack first attempts to convert the non-integer

Georg Brandlba83f822010-03-14 09:50:54 +00003134- Issue #1530559: When passing a non-integer argument to struct.pack with *any*
3135 integer format code (one of 'bBhHiIlLqQ'), struct.pack attempts to use the
3136 argument's __int__ method to convert to an integer before packing. It also
Georg Brandlfee0f442010-05-22 21:26:21 +00003137 produces a DeprecationWarning in this case. (In Python 2.6, the behaviour was
3138 inconsistent: __int__ was used for some integer codes but not for others, and
3139 the set of integer codes for which it was used differed between native packing
3140 and standard packing.)

3388 and add the additional members returned in an OSVERSIONINFOEX structure. The
3389 new members are service_pack_major, service_pack_minor, suite_mask, and

Georg Brandlba83f822010-03-14 09:50:54 +00003392- Issue #7561: Operations on empty bytearrays (such as ``int(bytearray())``)
3393 could crash in many places because of the ``PyByteArray_AS_STRING()`` macro
3394 returning NULL. The macro now returns a statically allocated empty string
3395 instead.

3405 strings,
3406 (2) a crash in dtoa.c that occurred in debug builds when parsing certain long
3407 numeric strings corresponding to subnormal values,

Antoine Pitroud840e512010-02-04 20:20:18 +00003440- Issue #4772: Raise a ValueError when an unknown Bluetooth protocol is
Georg Brandlba83f822010-03-14 09:50:54 +00003441 specified, rather than fall through to AF_PACKET (in the ``socket`` module).
Antoine Pitroud840e512010-02-04 20:20:18 +00003442 Also, raise ValueError rather than TypeError when an unknown TIPC address
3443 type is specified. Patch by Brian Curtin.

Antoine Pitrouf3fa0742010-01-31 22:26:04 +00003447- Issue #6939: Fix file I/O objects in the `io` module to keep the original
Georg Brandlba83f822010-03-14 09:50:54 +00003448 file position when calling `truncate()`. It would previously change the file
3449 position to the given argument, which goes against the tradition of
Antoine Pitrouf3fa0742010-01-31 22:26:04 +00003450 ftruncate() and other truncation APIs. Patch by Pascal Chambon.
3451
Georg Brandlba83f822010-03-14 09:50:54 +00003452- Issue #7610: Reworked implementation of the internal ``zipfile.ZipExtFile``
3453 class used to represent files stored inside an archive. The new
3454 implementation is significantly faster and can be wrapped in a
3455 ``io.BufferedReader`` object for more speedups. It also solves an issue
3456 where interleaved calls to ``read()`` and ``readline()`` give wrong results.
3457 Patch by Nir Aides.

Benjamin Petersona43f34c2010-01-25 03:31:13 +00003466
Georg Brandlba83f822010-03-14 09:50:54 +00003467- Issue #7748: Since unicode values are supported for some metadata options in
3468 Distutils, the DistributionMetadata get_* methods will now return an utf-8
3469 encoded string for them. This ensures that the upload and register commands
3470 send the correct values to PyPI without any error.

Ronald Oussoren315cd0c2009-11-19 16:25:21 +00003740
Georg Brandlba83f822010-03-14 09:50:54 +00003741- Issue #7117: ``repr(x)`` for a float x returns a result based on the shortest
3742 decimal string that's guaranteed to round back to x under correct rounding
3743 (with round-half-to-even rounding mode). Previously it gave a string based on
3744 rounding x to 17 decimal digits. repr(x) for a complex number behaves
3745 similarly. On platforms where the correctly-rounded strtod and dtoa code is
3746 not supported (see below), repr is unchanged.
Mark Dickinsonb678de82009-11-19 18:41:49 +00003747
Georg Brandlba83f822010-03-14 09:50:54 +00003748- Issue #7117: On almost all platforms: float-to-string and string-to-float
3749 conversions within Python are now correctly rounded. Places these conversions
3750 occur include: str for floats and complex numbers; the float and complex
3751 constructors; old-style and new-style numeric formatting; serialization and
3752 deserialization of floats and complex numbers using marshal, pickle and json;
3753 parsing of float and imaginary literals in Python code; Decimal-to-float
3754 conversion.
Mark Dickinsonb678de82009-11-19 18:41:49 +00003755
Georg Brandlba83f822010-03-14 09:50:54 +00003756 The conversions use a Python-adapted version of David Gay's well-known dtoa.c,
3757 providing correctly-rounded strtod and dtoa C functions. This code is
3758 supported on Windows, and on Unix-like platforms using gcc, icc or suncc as
3759 the C compiler. There may be a small number of platforms on which correct
3760 operation of this code cannot be guaranteed, so the code is not used: notably,
3761 this applies to platforms where the C double format is not IEEE 754 binary64,
3762 and to platforms on x86 hardware where the x87 FPU is set to 64-bit precision
3763 and Python's configure script is unable to determine how to change the FPU
3764 precision. On these platforms conversions use the platform strtod and dtoa,
3765 as before.

Georg Brandlba83f822010-03-14 09:50:54 +00003767- Issue #7117: Backport round implementation from Python 3.x. ``round()`` now
3768 uses the correctly-rounded string <-> float conversions described above (when
3769 available), and so produces correctly rounded results that will display nicely
3770 under the float repr. There are two related small changes: (1) round now
3771 accepts any class with an ``__index__()`` method for its second argument (but
3772 no longer accepts floats for the second argument), and (2) an excessively
3773 large second integer argument (e.g., ``round(1.234, 10**100)``) no longer
3774 raises an exception.

Georg Brandlba83f822010-03-14 09:50:54 +00003921- Issue #5920: For ``float.__format__()``, change the behavior with the empty
3922 presentation type (that is, not one of 'e', 'f', 'g', or 'n') to be like 'g'
3923 but with at least one decimal point and with a default precision
3924 of 12. Previously, the behavior the same but with a default precision of 6.
3925 This more closely matches ``str()``, and reduces surprises when adding

Georg Brandlba83f822010-03-14 09:50:54 +00004067- Issue #1180193: When importing a module from a .pyc (or .pyo) file with an
4068 existing .py counterpart, override the co_filename attributes of all code
4069 objects if the original filename is obsolete (which can happen if the file has

Amaury Forgeot d'Arcdc619012008-11-22 20:01:18 +00004115- Issue #3996: On Windows, the PyOS_CheckStack function would cause the

4117 instead of throwing a MemoryError.
4118
Georg Brandlba83f822010-03-14 09:50:54 +00004119- Issue #3689: The list reversed iterator now supports __length_hint__ instead

4124
Georg Brandlba83f822010-03-14 09:50:54 +00004125- Issue #4233: Changed semantic of ``_fileio.FileIO``'s ``close()`` method on
4126 file objects with closefd=False. The file descriptor is still kept open but
4127 the file object behaves like a closed file. The ``FileIO`` object also got a
4128 new readonly attribute ``closefd``.

4147
Benjamin Peterson399b1fe2008-10-25 02:53:28 +00004148- Using ``nonlocal`` as a variable name will now raise a Py3k SyntaxWarning
Georg Brandl7fb00ad2008-10-25 07:00:52 +00004149 because it is a reserved word in 3.x.

Georg Brandlba83f822010-03-14 09:50:54 +00004151- On windows, ``os.chdir()`` given unicode was not working if
4152 GetCurrentDirectoryW returned a path longer than MAX_PATH. (But It's doubtful
4153 this code path is really executed because I cannot move to such directory on
4154 win2k)
Hirokazu Yamamoto10a018c2008-10-09 10:00:30 +00004155
Georg Brandlba83f822010-03-14 09:50:54 +00004156- Issue #4069: When ``set.remove(element)`` is used with a set element, the
4157 element is temporarily replaced with an equivalent frozenset. But the
4158 eventual KeyError would always report the empty ``frozenset()`` as the missing
4159 key. Now it correctly refers to the initial element.

Walter Dörwalded960ac2009-05-03 22:36:33 +00004179- Issue #5108: Handle %s like %S and %R in PyUnicode_FromFormatV(): Call
4180 PyUnicode_DecodeUTF8() once, remember the result and output it in a second
4181 step. This avoids problems with counting UTF-8 bytes that ignores the effect
4182 of using the replace error handler in PyUnicode_DecodeUTF8().
4183
Walter Dörwald726ba8e2009-05-06 14:32:35 +00004184- Issue #3739: The unicode-internal encoder now reports the number of characters

4186
Georg Brandlba83f822010-03-14 09:50:54 +00004187- Issue #2422: When compiled with the ``--with-valgrind`` option, the pymalloc
4188 allocator will be automatically disabled when running under Valgrind. This
4189 gives improved memory leak detection when running under Valgrind, while taking
4190 advantage of pymalloc at other times.

4261 zipfiles, directories and other valid sys.path entries that contain a
Nick Coghlan49868cb2009-11-15 07:30:34 +00004262 __main__.py file. This allows applications that run other Python scripts to
4263 support the same flexibility as the CPython command line itself.

4267 timeout is 20 seconds, which should be amply sufficient for local connections.

5556
Amaury Forgeot d'Arc05e34492008-09-10 22:04:45 +00005557- Issue #3743: In a few places, PY_FORMAT_SIZE_T was incorrectly used with
5558 PyString_FromFormat or PyErr_Format to display size_t values. The macro
5559 PY_FORMAT_SIZE_T is designed to select the correct format for the OS
5560 ``printf`` function, whereas PyString_FromFormat has an independent
5561 implementation and uses "%zd" on all platforms for size_t values.
5562 This makes a difference on win64, where ``printf`` needs "%Id" to display
5563 64bit values.

Benjamin Peterson97179b02008-09-09 20:55:01 +00005565- Issue #3634: _weakref.ref(Exception).__init__() gave invalid return value on

5569 object; previously an int would be returned for small values. the __long__
5570 method is allowed to return either an int or a long, but the behaviour of

Antoine Pitroud4ae97b2008-08-29 18:39:48 +00005580 was correctly parsed but parsing of subsequent arguments failed.
5581
Vinay Sajip35e3b032008-09-01 14:33:59 +00005582- Issue #2534: speed up isinstance() and issubclass() by 50-70%, so as to
Antoine Pitrou0668c622008-08-26 22:42:08 +00005583 match Python 2.5 speed despite the __instancecheck__ / __subclasscheck__
5584 mechanism. In the process, fix a bug where isinstance() and issubclass(),
5585 when given a tuple of classes as second argument, were looking up
5586 __instancecheck__ / __subclasscheck__ on the tuple rather than on each
5587 type object.

Gregory P. Smithd7122032008-09-02 05:36:11 +00005673- Issue #3708: os.urandom no longer goes into an infinite loop when passed a
5674 non-integer floating point number.
5675
Vinay Sajip65d66e12008-09-04 07:31:21 +00005676- Issue #3110: multiprocessing fails to compiel on solaris 10 due to missing

5681
Jesse Noller438195f2009-01-18 21:04:36 +00005682- Issue #4301: Patch the logging module to add processName support, remove
5683 _check_logger_class from multiprocessing.
5684
Amaury Forgeot d'Arc293924b2008-09-02 23:19:56 +00005685- Issue #2975: When compiling several extension modules with Visual Studio 2008
5686 from the same python interpreter, some environment variables would grow
5687 without limit.
5688
Benjamin Peterson37346b22008-08-23 20:27:43 +00005689- Issue #3643: Added a few more checks to _testcapi to prevent segfaults by
5690 exploitation of poor argument checking.
5691
Gerhard Häringef2276b2008-09-12 13:54:06 +00005692- sqlite3: Changed docstring of iterdump() to mark method as "Non-standard".

5705 wrapper for warnings.catch_warnings() that makes it easier to check
5706 that expected warning messages are being reported.
5707

Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00005726What's New in Python 2.6 beta 3?
5727================================
5728
Barry Warsaw07a4a382008-08-21 01:15:08 +00005729*Release date: 20-Aug-2008*
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00005730
5731Core and Builtins
5732-----------------
5733
Guido van Rossumf8402962008-08-20 15:01:50 +00005734- Issue #1878: Remove Py_TPFLAGS_HAVE_VERSION_TAG from
5735 Py_TPFLAGS_DEFAULT when not building the core. This means 3rd party
5736 extensions do not automatically benefit from the class attribute
5737 cache; they will have to explicitly add Py_TPFLAGS_HAVE_VERSION_TAG
5738 to their tp_flags field if they care. This is a backwards
5739 compatibility feature; in 3.0, all types will use the cache by
5740 default.
5741
Benjamin Petersonf647dc12008-08-20 01:27:30 +00005742- Keyword arguments can now follow starred arguments. (``f(a, *args,
5743 keyword=23)`` is now valid syntax.)
5744
Thomas Heller0ad5ae02008-08-19 19:25:04 +00005745- ctypes function pointers that are COM methods have a boolean True
5746 value again.
5747
Martin v. Löwisf91d46a2008-08-12 14:49:50 +00005748- Issue #3139: Make buffer-interface thread-safe wrt. PyArg_ParseTuple,
5749 by denying s# to parse objects that have a releasebuffer procedure,
5750 and introducing s*.
5751
Georg Brandl1e13ea92008-08-11 09:07:59 +00005752- Issue #3537: Fix an assertion failure when an empty but presized dict
5753 object was stored in the freelist.
5754
Mark Dickinsonb6467572008-08-04 21:30:09 +00005755- Issue #1481296: Make long(float('nan')) and int(float('nan')) raise
5756 ValueError consistently across platforms.
5757
Amaury Forgeot d'Arc39fd6722008-07-31 21:28:03 +00005758- Issue #3479: On platforms where sizeof(int) is smaller than sizeof(long)
5759 (64bit Unix, for example), unichr() would truncate its argument and return
5760 u'\x00' for unichr(2**32). Now it properly raises an OverflowError.
5761
Neal Norwitze7d8be82008-07-31 17:17:14 +00005762- Apply security patches from Apple.
5763
Amaury Forgeot d'Arc246daed2008-07-31 00:42:16 +00005764- Issue #2542: Now that issubclass() may call arbitrary code, ensure that
5765 PyErr_ExceptionMatches returns 0 when an exception occurs there.
5766
Antoine Pitrou92f82162008-07-25 22:22:08 +00005767- Issue #1819: function calls with several named parameters are now on
5768 average 35% faster (as measured by pybench).
5769
Amaury Forgeot d'Arce4921fe2008-07-21 22:00:38 +00005770- Issue #2378: An unexpected UnboundLocalError or NameError could appear when
5771 the python debugger steps into a class statement: the free variables (local
5772 variables defined in an outer scope) would be deleted from the outer scope.
5773
Gregory P. Smith0470bab2008-07-22 04:46:32 +00005774- Issue #2620: Overflow checking when allocating or reallocating memory
5775 was not always being done properly in some python types and extension
5776 modules. PyMem_MALLOC, PyMem_REALLOC, PyMem_NEW and PyMem_RESIZE have
5777 all been updated to perform better checks and places in the code that
5778 would previously leak memory on the error path when such an allocation
5779 failed have been fixed.
5780
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00005781Library
5782-------
5783
Hirokazu Yamamoto838c79f2008-08-20 13:14:07 +00005784- Issue #3612: Added some missing basic types in ctypes.wintypes.
5785
Benjamin Petersone977ad42008-08-20 01:42:01 +00005786- The methods ``is_in_tuple()``, ``is_vararg()``, and ``is_keywordarg()`` of
5787 symtable.Symbol have been deprecated for removal in 3.0 and the next release.
5788
Amaury Forgeot d'Arc351ffb82008-08-18 19:23:47 +00005789- Issue #2234: distutils failed for some versions of the cygwin compiler. The
5790 version reported by these tools does not necessarily follow the python
5791 version numbering scheme, so the module is less strict when parsing it.
5792
Nick Coghlanf70385a2008-08-18 12:42:46 +00005793- Issue #2235: Added Py3k warnings for types which will become unhashable
5794 under the stricter __hash__ inheritance rules in 3.0. Several types
5795 which did not meet the rules for hash invariants and were already
5796 unhashable in 3.0 have now been explicitly flagged as unhashable in
5797 2.6 as well (collections.Mapping, collections.Set, unittest.TestSuite,
5798 xml.dom.minidom.NamedNodeMap, numbers.Number, UserList.UserList)
5799
Brett Cannon88f801d2008-08-18 00:46:22 +00005800- Update __all__ for cookielib, csv, os, urllib2, and weakref to include things
5801 imported into the module but exposed as part of the module's API.
5802
Brett Cannon7b96f072008-08-18 00:41:11 +00005803- Remove an unneeded import of abc.ABCMeta from 'inspect'.
5804
Brett Cannon46225e72008-08-18 00:36:52 +00005805- Remove unneeded imports of 'sys' and 'warnings' from 'io'.

Brett Cannon25c9d6a2008-08-17 22:10:11 +00005807- Remove unneeded imports of 'warnings' from shelve, filecmp, and dummy_thread.
5808
Hirokazu Yamamoto41a81eb2008-08-17 13:10:46 +00005809- Issue #3575: Incremental decoder's decode function now takes bytearray
5810 by using 's*' instead of 't#'.
5811
Mark Dickinson3e4caeb2009-02-21 20:27:01 +00005812- Issue #2222: Fixed reference leak when occurred os.rename()
Hirokazu Yamamoto7f30a682008-08-17 09:46:56 +00005813 fails unicode conversion on 2nd parameter. (windows only)
5814
Georg Brandl222e2082010-08-01 22:27:39 +00005815- Issue #2464: urllib2 now supports a malformation in the URL received
Facundo Batista94f243a2008-08-17 03:38:39 +00005816 in a redirect.
5817
Brett Cannonabe423e2008-08-16 21:47:07 +00005818- Silence the DeprecationWarning raised when importing mimetools in
Brett Cannon721b1452008-08-16 22:00:27 +00005819 BaseHTTPServer, cgi (and rfc822), httplib.
Brett Cannonabe423e2008-08-16 21:47:07 +00005820
Facundo Batistaeb90b782008-08-16 14:44:07 +00005821- Issue #2776: fixed small issue when handling an URL with double slash
5822 after a 302 response in the case of not going through a proxy.
5823
Antoine Pitroub90a8be2008-08-15 21:03:21 +00005824- Issue #2676: in the email package, content-type parsing was hanging on
5825 pathological input because of quadratic or exponential behaviour of a
5826 regular expression.
5827
Antoine Pitrou11ec65d2008-08-14 21:04:30 +00005828- Issue #3476: binary buffered reading through the new "io" library is now
5829 thread-safe.
5830
Brett Cannonbf3157b2008-08-14 05:00:03 +00005831- Silence the DeprecationWarning of rfc822 when it is imported by mimetools
5832 since mimetools itself is deprecated. Because modules are cached, all
5833 subsequent imports of rfc822 will not raise a visible DeprecationWarning.
5834
Antoine Pitrou9fcd4b32008-08-11 17:21:36 +00005835- Issue #3134: shutil referenced undefined WindowsError symbol.
5836
Robert Schuppenies14646332008-08-10 11:01:53 +00005837- Issue #1342811: Fix leak in Tkinter.Menu.delete. Commands associated to
5838 menu entries were not deleted.
5839
Brett Cannon83e81842008-08-09 23:30:55 +00005840- Copied the implementation of reduce() to _functools.reduce() to have a
5841 version that did not raise a DeprecationWarning under -3.
5842
Antoine Pitrou76b8bee2008-08-09 17:27:23 +00005843- Issue #3205: When iterating over a BZ2File fails allocating memory, raise
5844 a MemoryError rather than silently stop the iteration.
5845
Guido van Rossum59ce9012008-08-09 14:55:34 +00005846- Issue #3487: sre "bytecode" validator. Passing invalid "re-bytecode"
5847 to _sre.compile() will now be rejected. This should not affect anybody
5848 since the re.compile() function never generates invalid re-bytecode.
5849
Skip Montanaroa032bf42008-08-08 22:52:51 +00005850- Issue #3436: Make csv.DictReader's fieldnames attribute a property so that
5851 upon first access it can be automatically initialized from the csv file if
5852 it wasn't initialized during instantiation.
5853
Brett Cannon3aa2a492008-08-06 22:28:09 +00005854- Issue #2338: Create imp.reload() to help with transitioning to Python 3.0 as
5855 the reload() built-in has been removed.
5856
Brett Cannon7e30b672008-08-04 21:52:25 +00005857- Changed code in the following modules/packages to remove warnings raised
Brett Cannonc1b76e42008-08-09 23:06:16 +00005858 while running under the ``-3`` flag: aifc, asynchat, asyncore, bdb, bsddb,

5866 raised an AttributeError.
5867
Benjamin Peterson01a24322008-07-28 23:35:27 +00005868- Issue #2523: Fix quadratic behaviour when read()ing a binary file without
Antoine Pitroude781a42008-08-09 12:43:23 +00005869 asking for a specific length. This problem only affected files opened
5870 using the new "io" module, not the built-in open() function.
Benjamin Peterson01a24322008-07-28 23:35:27 +00005871
Mark Dickinsonfe84cce2008-07-27 06:39:07 +00005872- Issue #3449: Update decimal module to use most recent specification
5873 (v. 1.68) and tests (v. 2.58) from IBM.

5894
Antoine Pitrou5fdfa3e2008-07-25 19:42:26 +00005895- Issue #3394: zipfile.writestr sets external attributes when passed a
5896 file name rather than a ZipInfo instance, so files are extracted with
5897 mode 0600 rather than 000 under Unix.
5898
Gregory P. Smitha36f8fe2008-08-04 00:13:29 +00005899- Issue #1857: subprocess.Popen.poll gained an additional _deadstate keyword
5900 argument in python 2.5, this broke code that subclassed Popen to include its
5901 own poll method. Fixed my moving _deadstate to an _internal_poll method.

Nick Coghlan6e8fef02008-08-18 13:14:22 +00005911- Issue #2235: the C API function PyObject_HashNotImplemented and its
5912 interaction with the tp_hash slot (added in 2.6b2) are now documented
5913
Nick Coghlan2a0c2b12008-08-04 12:47:17 +00005914- Issue #643841: The language reference now provides more detailed
5915 coverage of the lookup process for special methods. The disclaimers
5916 regarding lack of coverage of new-style classes have also been
5917 removed, since the coverage is now fairly reasonable.

Raymond Hettingere3ae6552008-06-20 04:18:15 +00005920What's New in Python 2.6 beta 2?
5921================================
5922
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00005923*Release date: 17-Jul-2008*
5924
Raymond Hettingere3ae6552008-06-20 04:18:15 +00005925Core and Builtins
5926-----------------
5927
Georg Brandl3e483f62008-07-16 22:57:41 +00005928- Issue #3156: Fix inconsistent behavior of the bytearray type: all
5929 its methods now allow for items objects that can be converted to
5930 an integer using operator.index().
5931
Mark Dickinson64b7e502008-07-16 09:40:03 +00005932- Issue #3360: Fix incorrect parsing of '020000000000.0', which
5933 produced a ValueError instead of giving the correct float.
5934
Eric Smitha5fa5a22008-07-16 00:11:49 +00005935- Issue #3083: Add alternate (#) formatting for bin, oct, hex output
5936 for str.format(). This adds the prefix 0b, 0o, or 0x, respectively.
5937
Mark Dickinson7103aa42008-07-15 19:08:33 +00005938- Issue #3008: the float type has a new instance method 'float.hex'
5939 and a new class method 'float.fromhex' to convert floating-point
5940 numbers to and from hexadecimal strings, respectively.
5941
Nick Coghlan6d6bd442008-07-15 15:40:22 +00005942- Issue #2235: __hash__ is once again inherited by default. To allow
5943 collections.Hashable to remain meaningful in the presence of the
5944 default hash implementation (object.__hash__), it is now possible
5945 to explicit block inheritance of hash by setting __hash__=None at
5946 the Python level, or tp_hash=PyObject_HashNotImplemented at the C
5947 level.
5948
Nick Coghlanb028f502008-07-13 14:52:36 +00005949- Issue #3221: Issue a RuntimeWarning instead of raising SystemError if
5950 the parent module cannot be found while performing an absolute import.
5951 This means that an incorrectly defined __package__ attribute will
5952 now only prevent relative imports in that module rather than causing
5953 all imports from that module to fail.
5954
Nick Coghlan14ff9942008-07-08 14:21:42 +00005955- Issue #2517: Allow unicode messages in Exceptions again by correctly
5956 bypassing the instance dictionary when looking up __unicode__ on

6015 both unnecessary (HTTP allows text content to be sent in several forms) and
Andrew M. Kuchlingcc3f2b12008-07-10 14:43:31 +00006016 wrong because the actual transmitted size could differ from the

Georg Brandl5cc774e2008-06-11 20:28:06 +00006426 PPC64 and x86_64 support in one binary).
Ronald Oussoren5640ce22008-06-05 12:58:24 +00006427
6428 This is controlled by the configure argument ``--with-universal-archs``:

6431
6432 - ``--with-universal-archs=32-bit``: install 2-way universal, 32-bit (the default)
6433
6434 - ``--with-universal-archs=64-bit``: install 2-way universal, 64-bit
6435

Georg Brandl3ee81df2008-05-17 18:14:43 +00006488- Issue #1631171: Re-implement the 'warnings' module in C (the
6489 original Python code has been kept as backup). This will allow for
6490 using the 'warning's machinery in such places as the parser where
6491 use of pure Python code is not possible. Both the ``showarning()``
6492 and ``formatwarning()`` gain an optional 'line' argument which is
6493 not called by default for backwards-compatibility reasons. Setting
6494 ``warnings.showwarning()`` to an implementation that lacks support
6495 for the ``line`` argument will raise a DeprecationWarning.

Georg Brandl3ee81df2008-05-17 18:14:43 +00006558- Issue #2550: The approach used by client/server code for obtaining
6559 ports to listen on in network-oriented tests has been refined in an
6560 effort to facilitate running multiple instances of the entire
6561 regression test suite in parallel without issue.
6562 test_support.bind_port() has been fixed such that it will always
6563 return a unique port -- which wasn't always the case with the
6564 previous implementation, especially if socket options had been set
6565 that affected address reuse (i.e. SO_REUSEADDR, SO_REUSEPORT). The
6566 new implementation of bind_port() will actually raise an exception
6567 if it is passed an AF_INET/SOCK_STREAM socket with either the
6568 SO_REUSEADDR or SO_REUSEPORT socket option set. Furthermore, if
6569 available, bind_port() will set the SO_EXCLUSIVEADDRUSE option on
6570 the socket it's been passed. This currently only applies to
6571 Windows. This option prevents any other sockets from binding to the
6572 host/port we've bound to, thus removing the possibility of the
6573 'non-deterministic' behaviour, as Microsoft puts it, that occurs
6574 when a second SOCK_STREAM socket binds and accepts to a host/port
6575 that's already been bound by another socket. The optional preferred
6576 port parameter to bind_port() has been removed. Under no
6577 circumstances should tests be hard coding ports!
6578
6579 test_support.find_unused_port() has also been introduced, which will
6580 pass a temporary socket object to bind_port() in order to obtain an
6581 unused port. The temporary socket object is then closed and
6582 deleted, and the port is returned. This method should only be used
6583 for obtaining an unused port in order to pass to an external program
6584 (i.e. the -accept [port] argument to openssl's s_server mode) or as
6585 a parameter to a server-oriented class that doesn't give you direct
6586 access to the underlying socket used.
6587
6588 Finally, test_support.HOST has been introduced, which should be used
6589 for the host argument of any relevant socket calls (i.e. bind and
6590 connect).
Trent Nelsone41b0062008-04-08 23:47:30 +00006591
6592 The following tests were updated to following the new conventions:
Georg Brandl3ee81df2008-05-17 18:14:43 +00006593 test_socket, test_smtplib, test_asyncore, test_ssl, test_httplib,
Trent Nelsone41b0062008-04-08 23:47:30 +00006594 test_poplib, test_ftplib, test_telnetlib, test_socketserver,
6595 test_asynchat and test_socket_ssl.
6596
Georg Brandl3ee81df2008-05-17 18:14:43 +00006597 It is now possible for multiple instances of the regression test
6598 suite to run in parallel without issue.

Eric Smitha73fbe72008-02-23 03:09:44 +00006877- Added the future_builtins module, which contains hex() and oct().
6878 These are the PEP 3127 version of these functions, designed to be
6879 compatible with the hex() and oct() builtins from Python 3.0. They
6880 differ slightly in their output formats from the existing, unchanged
6881 Python 2.6 builtins. The expected usage of the future_builtins
6882 module is:
6883 from future_builtins import hex, oct
6884
Eric Smith7ef40bf2008-02-20 23:34:22 +00006885- Issue #1600: Modifed PyOS_ascii_formatd to use at most 2 digit
6886 exponents for exponents with absolute value < 100. Follows C99
6887 standard. This is a change on Windows, which would use 3 digits.
6888 Also, added 'n' to the formats that PyOS_ascii_formatd understands,
6889 so that any alterations it does to the resulting string will be
6890 available in stringlib/formatter.h (for float.__format__).
6891
Eric Smith5a3c1352008-02-19 13:21:56 +00006892- Implemented PEP 3101, Advanced String Formatting. This adds a new
6893 builtin format(); a format() method for str and unicode; a
6894 __format__() method to object, str, unicode, int, long, float, and
6895 datetime; the class string.Formatter; and the C API
6896 PyObject_Format().
6897
Georg Brandl3ee81df2008-05-17 18:14:43 +00006898- Fixed several potential crashes, all caused by specially crafted
6899 __del__ methods exploiting objects in temporarily inconsistent
6900 state.
Amaury Forgeot d'Arc632fad32008-02-16 20:55:24 +00006901
Vinay Sajipb7edfc42008-04-02 21:10:23 +00006902- Issue #2115: Important speedup in setting __slot__ attributes. Also
Georg Brandl3ee81df2008-05-17 18:14:43 +00006903 prevent a possible crash: an Abstract Base Class would try to access
6904 a slot on a registered virtual subclass.

Georg Brandl3ee81df2008-05-17 18:14:43 +00006909- Clear all free lists during a gc.collect() of the highest generation
6910 in order to allow pymalloc to free more arenas. Python may give back
6911 memory to the OS earlier.
Christian Heimes3b718a72008-02-14 12:47:33 +00006912
Georg Brandl3ee81df2008-05-17 18:14:43 +00006913- Issue #2045: Fix an infinite recursion triggered when printing a
6914 subclass of collections.defaultdict, if its default_factory is set
6915 to a bound method.
Amaury Forgeot d'Arcb01aa432008-02-08 00:56:02 +00006916
Christian Heimesf75dbef2008-02-08 00:11:31 +00006917- Fixed a minor memory leak in dictobject.c. The content of the free
6918 list was not freed on interpreter shutdown.
6919
Georg Brandl21e99f42010-03-07 15:23:59 +00006920- Limit free list of method and built-in function objects to 256

Christian Heimes6075a822008-02-06 12:44:34 +00006922
Georg Brandl3ee81df2008-05-17 18:14:43 +00006923- Patch #1953: Added ``sys._compact_freelists()`` and the C API
6924 functions ``PyInt_CompactFreeList`` and ``PyFloat_CompactFreeList``
Christian Heimes422051a2008-02-04 18:00:12 +00006925 to compact the internal free lists of pre-allocted ints and floats.
6926
Georg Brandl3ee81df2008-05-17 18:14:43 +00006927- Issue #1983: Fixed return type of fork(), fork1() and forkpty()
6928 calls. Python expected the return type int but the fork familie
6929 returns pi_t.
Christian Heimes951cc0f2008-01-31 23:08:23 +00006930
Georg Brandl3ee81df2008-05-17 18:14:43 +00006931- Issue #1678380: Fix a bug that identifies 0j and -0j when they

6941 the internal lookup cache for ref leak tests.
Christian Heimes908caac2008-01-27 23:34:59 +00006942
Georg Brandl3ee81df2008-05-17 18:14:43 +00006943- Patch #1473257: generator objects gain a gi_code attribute. This is
6944 the same object as the func_code attribute of the function that
6945 produced the generator.
Georg Brandl0cdf9a32008-01-26 14:14:20 +00006946
Georg Brandl3ee81df2008-05-17 18:14:43 +00006947- Issue #1920: "while 0" statements were completely removed by the
6948 compiler, even in the presence of an "else" clause, which is
6949 supposed to be run when the condition is false. Now the compiler
6950 correctly emits bytecode for the "else" suite.
Amaury Forgeot d'Arc31eaafe2008-01-24 22:59:25 +00006951
Guido van Rossumeead05f2008-01-24 18:21:02 +00006952- A few crashers fixed: weakref_in_del.py (issue #1377858);
6953 loosing_dict_ref.py (issue #1303614, test67.py);
6954 borrowed_ref_[34].py (not in tracker).
6955
Vinay Sajipd7cf32e2008-01-24 12:43:33 +00006956- Issue #1069410: The "can't load dll" message box on Windows is
Christian Heimesb2302ba2008-01-23 17:15:06 +00006957 suppressed while an extension is loaded by calling SetErrorMode in

6959
Georg Brandl3ee81df2008-05-17 18:14:43 +00006960- Issue #1915: Python compiles with --enable-unicode=no again. However
Christian Heimes082c9b02008-01-23 14:20:50 +00006961 several extension methods and modules do not work without unicode
6962 support.
6963
Georg Brandl26543b12008-01-21 18:36:51 +00006964- Issue #1882: when compiling code from a string, encoding cookies in the
6965 second line of code were not always recognized correctly.
6966
Georg Brandl14404b62008-01-19 19:27:05 +00006967- Issue #1679: "0x" was taken as a valid integer literal.
6968
Georg Brandl6caad7d2008-01-26 14:19:22 +00006969- Issue #1865: ``bytes`` as an alias for ``str`` and b"" as an alias "" were
Christian Heimes288e89a2008-01-18 18:24:07 +00006970 added.
6971
Christian Heimesc94e2b52008-01-14 04:13:37 +00006972- sys.float_info / PyFloat_GetInfo: The floating point information
6973 object was converted from a dict to a specialized structseq object.
6974
Georg Brandl3ee81df2008-05-17 18:14:43 +00006975- Patch #1816: Added sys.flags structseq. It exposes the status of
6976 most command line arguments and PYTHON* environment variables.
Christian Heimesf31b69f2008-01-14 03:42:48 +00006977
Georg Brandl3ee81df2008-05-17 18:14:43 +00006978- Objects/structseq.c: Implemented new structseq representation. The

6980 readable.
Christian Heimes9c201962008-01-14 03:33:52 +00006981
Georg Brandl3ee81df2008-05-17 18:14:43 +00006982- Patch #1700288: added a type attribute cache that caches method

Christian Heimes0a8143f2007-12-18 23:22:54 +00007006
Georg Brandl3ee81df2008-05-17 18:14:43 +00007007- Compiler now generates simpler and faster code for dictionary
7008 literals. The oparg for BUILD_MAP now indicates an estimated
7009 dictionary size. There is a new opcode, STORE_MAP, for adding
7010 entries to the dictionary.

7053
Georg Brandl21e99f42010-03-07 15:23:59 +00007054- The enumerate() built-in function is no longer bounded to sequences
Georg Brandl3ee81df2008-05-17 18:14:43 +00007055 smaller than LONG_MAX. Formerly, it raised an OverflowError. Now,
7056 automatically shifts from ints to longs.
Raymond Hettinger8f669372007-10-03 21:18:11 +00007057
Georg Brandl3ee81df2008-05-17 18:14:43 +00007058- Issue #1686386: Tuple's tp_repr did not take into account the
7059 possibility of having a self-referential tuple, which is possible
7060 from C code. Nor did object's tp_str consider that a type's tp_str
7061 could do something that could lead to an inifinite recursion.
7062 Py_ReprEnter() and Py_EnterRecursiveCall(), respectively, fixed the
7063 issues.

Georg Brandl3ee81df2008-05-17 18:14:43 +00007065- Issue #1164: It was possible to trigger deadlock when using the
7066 'print' statement to write to a file since the GIL was not released
7067 as needed. Now PyObject_Print() does the right thing along with
7068 various tp_print implementations of the built-in types and those in
7069 the collections module.

Georg Brandl3ee81df2008-05-17 18:14:43 +00007079 PyObject_Call() never calling back out to Python code to trigger
7080 recursion depth updates/checks. Required the creation of a static
7081 RuntimeError instance in case normalizing an exception put the
7082 recursion check value past its limit. Fixes crashers

7107
Collin Winter62903052007-05-18 23:11:24 +00007108- except clauses may now be spelled either "except E, target:" or

7130
Guido van Rossum143b5642007-03-23 04:58:42 +00007131- Bug #1683368: The object.__init__() and object.__new__() methods are
7132 now stricter in rejecting excess arguments. The only time when
7133 either allows excess arguments is when it is not overridden and the
7134 other one is. For backwards compatibility, when both are
7135 overridden, it is a deprecation warning (for now; maybe a Py3k
Guido van Rossum234b1ff2007-03-23 19:39:01 +00007136 warning later). Also, type.__init__() insists on the same signature
7137 as supported by type.__new__().

Georg Brandl3ee81df2008-05-17 18:14:43 +00007139- Patch #1675423: PyComplex_AsCComplex() now tries to convert an
7140 object to complex using its __complex__() method before falling back
7141 to the __float__() method. Therefore, the functions in the cmath
7142 module now can operate on objects that define a __complex__()
7143 method.

Georg Brandl7b9c5552007-03-12 14:30:05 +00007161- Bug #1678647: write a newline after printing an exception in any
7162 case, even when converting the value to a string failed.
7163
Georg Brandl871f1bc2007-03-12 13:17:36 +00007164- The dir() function has been extended to call the __dir__() method on
Georg Brandl3ee81df2008-05-17 18:14:43 +00007165 its argument, if it exists. If not, it will work like before. This
7166 allows customizing the output of dir() in the presence of a
7167 __getattr__().

7177 raising a ValueError.
Collin Wintere38051d2007-03-09 20:33:07 +00007178
Georg Brandlaa2321b2007-03-07 00:40:28 +00007179- Patch #703779: unset __file__ in __main__ after running a file. This
Georg Brandl3ee81df2008-05-17 18:14:43 +00007180 makes the filenames the warning module prints much more sensible
7181 when a PYTHONSTARTUP file is used.

7196
Georg Brandl3ee81df2008-05-17 18:14:43 +00007197- When printing an unraisable error, don't print exceptions. before

7765
Georg Brandl92a6bae2007-03-13 17:43:32 +00007766- Patch #1603688: ConfigParser.SafeConfigParser now checks values that
Georg Brandl3ee81df2008-05-17 18:14:43 +00007767 are set for invalid interpolation sequences that would lead to

7824 TestCase and TestSuite subclasses (not instances) are no longer
7825 accepted in TestSuite.addTest(). This should cause no

7827 -- the failure just occurred later, with a more cumbersome
7828 exception.

Georg Brandl3ee81df2008-05-17 18:14:43 +00008109- Issue #829951: In the smtplib module, SMTP.starttls() now complies
8110 with RFC 3207 and forgets any knowledge obtained from the server not
8111 obtained from the TLS negotiation itself. Patch contributed by Bill
8112 Fenner.
Gregory P. Smith2b3ba582008-01-17 08:03:17 +00008113
Georg Brandl3ee81df2008-05-17 18:14:43 +00008114- Issue #1339: The smtplib.SMTP class has been refactored a bit such
Gregory P. Smithbde4ae42008-01-17 08:35:49 +00008115 that the SMTP.starttls() caller no longer needs to call ehlo()
8116 beforehand. SMTP.starttls() now raises an exception of the server
Georg Brandl3ee81df2008-05-17 18:14:43 +00008117 does not claim to support starttls. Adds the
8118 SMTP.ehlo_or_helo_if_needed() method. Patch contributed by Bill

Raymond Hettinger12e94202007-11-07 01:13:09 +00008202

Georg Brandl3ee81df2008-05-17 18:14:43 +00008217 time so that opening a database previously created with the DB_DUP
8218 or DB_DUPSORT flag set will keep the proper behavior on subsequent
8219 opens. Specifically: dictionary assignment to a DB object will
8220 replace all values for a given key when the database allows
8221 duplicate values. DB users should use DB.put(k, v) when they want
8222 to store duplicates; not DB[k] = v.
Gregory P. Smithec10a4a2007-11-05 02:32:26 +00008223

Raymond Hettingerdc1d1ba2007-11-07 02:45:46 +00008501- Add a FAST_LOOPS build option that speeds-up looping by trading away
Georg Brandl3ee81df2008-05-17 18:14:43 +00008502 periodic threadstate and signal checking in tight loops. By
8503 default, this option is turned-off. It should only be enabled in
8504 debugged, performance critical applications.

8555-----
8556
Georg Brandl3ee81df2008-05-17 18:14:43 +00008557- Unified naming convention for free lists and their limits. All free
8558 lists in Object/ are named ``free_list``, the counter ``numfree``
8559 and the upper limit is a macro ``PyName_MAXFREELIST`` inside an
8560 #ifndef block.
Christian Heimes5b970ad2008-02-06 13:33:44 +00008561
Georg Brandl3ee81df2008-05-17 18:14:43 +00008562- ``PySet_Add()`` can now modify a newly created frozenset. Similarly
8563 to ``PyTuple_SetItem``, it can be used to populate a brand new
8564 frozenset; but it does not steal a reference to the added item.

8576
Georg Brandl3ee81df2008-05-17 18:14:43 +00008577- Issue #1521: On 64bit platforms, using PyArgs_ParseTuple with the t#
8578 of w# format code incorrectly truncated the length to an int, even
8579 when PY_SSIZE_T_CLEAN is set. The str.decode method used to return
8580 incorrect results with huge strings.
Georg Brandl6caad7d2008-01-26 14:19:22 +00008581
Georg Brandl3ee81df2008-05-17 18:14:43 +00008582- Issue #1629: Renamed Py_Size, Py_Type and Py_Refcnt to Py_SIZE,

8602
8603- Make _PyGILState_NoteThreadState() static, it was not used anywhere
8604 outside of pystate.c and should not be necessary.
8605
Georg Brandl3ee81df2008-05-17 18:14:43 +00008606- ``PyImport_Import`` and ``PyImport_ImportModule`` now always do
8607 absolute imports. In earlier versions they might have used relative
8608 imports under some conditions.
Christian Heimes000a0742008-01-03 22:16:32 +00008609
Georg Brandl3ee81df2008-05-17 18:14:43 +00008610- Added case insensitive comparison methods ``PyOS_stricmp(char*,
8611 char*)`` and ``PyOS_strnicmp(char*, char*, Py_ssize_t)``.
Christian Heimes000a0742008-01-03 22:16:32 +00008612
Georg Brandl3ee81df2008-05-17 18:14:43 +00008613- Bug #1542693: remove semi-colon at end of PyImport_ImportModuleEx

Georg Brandl3ee81df2008-05-17 18:14:43 +00008638- Removed the macfs module. It had been deprecated since Python 2.5.
8639 This lead to the deprecation of macostools.touched() as it relied
