706 incorrect results with recent versions of Clang, as a result of the
Mark Dickinsona96b0d12011-09-24 09:01:16 +0100707 compiler optimizing the check away. Also fix similar overflow checks
708 in list_repeat (listobject.c) and islice_next (itertoolsmodule.c). These

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

Florent Xiclunac2279652012-02-12 14:49:03 +0100777- Issue #13994: Earlier partial revert of Distutils enhancements in 2.7
Ned Deilyc47a4592012-02-11 20:40:24 +0100778 has left two versions of customize_compiler, the original in
779 distutils.sysconfig and another copy in distutils.ccompiler, with some

Ned Deily0d0ea482012-02-10 12:59:06 +0100784- Issue #13590: On OS X 10.7 and 10.6 with Xcode 4.2, building
785 Distutils-based packages with C extension modules may fail because
786 Apple has removed gcc-4.2, the version used to build python.org
787 64-bit/32-bit Pythons. If the user does not explicitly override
788 the default C compiler by setting the CC environment variable,
789 Distutils will now attempt to compile extension modules with clang
790 if gcc-4.2 is required but not found. Also as a convenience, if
791 the user does explicitly set CC, substitute its value as the default
792 compiler in the Distutils LDSHARED configuration variable for OS X.
793 (Note, the python.org 32-bit-only Pythons use gcc-4.0 and the 10.4u
794 SDK, neither of which are available in Xcode 4. This change does not
795 attempt to override settings to support their use with Xcode 4.)

Ned Deily87e82bb2011-06-28 19:52:59 -07001068- Issue #9516: On Mac OS X, change Distutils to no longer globally attempt to
1069 check or set the MACOSX_DEPLOYMENT_TARGET environment variable for the
1070 interpreter process. This could cause failures in non-Distutils subprocesses
1071 and was unreliable since tests or user programs could modify the interpreter
1072 environment after Distutils set it. Instead, have Distutils set the the
1073 deployment target only in the environment of each build subprocess. It is
1074 still possible to globally override the default by setting
1075 MACOSX_DEPLOYMENT_TARGET before launching the interpreter; its value must be
1076 greater or equal to the default value, the value with which the interpreter
1077 was built.

1107 the ticker doesn't have to wind down to zero from the old starting point
1108 before the new interval takes effect. And if the user increases the
1109 interval, it makes sure the new limit takes effect right away rather have an
1110 early task switch before recognizing the new interval.

2029 with invalid characters after '=' in a Q-encoded word.
2030
Antoine Pitrou66b5df62010-09-27 18:16:46 +00002031- Issue #9950: Fix socket.sendall() crash or misbehaviour when a signal is
2032 received. Now sendall() properly calls signal handlers if necessary,
2033 and retries sending if these returned successfully, including on sockets
2034 with a timeout.

2041
Antoine Pitrou2c7d6852010-09-23 19:55:24 +00002042- Issue #9928: Properly initialize the types exported by the bz2 module.
2043
Antoine Pitrou6391b342010-09-14 18:48:19 +00002044- Issue #9854: The default read() implementation in io.RawIOBase now
2045 handles non-blocking readinto() returning None correctly.
2046
Antoine Pitrouf7f390a2010-09-14 14:37:18 +00002047- Issue #9729: Fix the signature of SSLSocket.recvfrom() and
2048 SSLSocket.sendto() to match the corresponding socket methods. Also,
2049 fix various SSLSocket methods to raise socket.error rather than an
2050 unhelpful TypeError when called on an unconnected socket. Original patch
2051 by Andrew Bennetts.
2052
Raymond Hettinger74f869e2010-09-13 22:14:36 +00002053- Issue #9826: OrderedDict.__repr__ can now handle self-referential
2054 values: d['x'] = d.

2060
Raymond Hettinger20397532010-09-12 02:11:45 +00002061- Issue #9825: removed __del__ from the definition of collections.OrderedDict.
2062 This prevents user-created self-referencing ordered dictionaries from
2063 becoming permanently uncollectable GC garbage. The downside is that
2064 removing __del__ means that the internal doubly-linked list has to wait for
2065 GC collection rather than freeing memory immediately when the refcnt drops
2066 to zero.
2067
Raymond Hettingerffd2a422010-09-10 10:47:22 +00002068- Issue #9816: random.Random.jumpahead(n) did not produce a sufficiently
Victor Stinnerd2f6ae62010-10-12 22:53:51 +00002069 different internal state for small values of n. Fixed by salting the
Raymond Hettingerffd2a422010-09-10 10:47:22 +00002070 value.
2071
Antoine Pitrouc818ed42010-09-07 21:40:25 +00002072- Issue #9792: In case of connection failure, socket.create_connection()
2073 would swallow the exception and raise a new one, making it impossible
2074 to fetch the original errno, or to filter timeout errors. Now the
2075 original error is re-raised.
2076
Antoine Pitrouf4f61712010-09-07 16:34:47 +00002077- Issue #9758: When fcntl.ioctl() was called with mutable_flag set to True,
2078 and the passed buffer was exactly 1024 bytes long, the buffer wouldn't
2079 be updated back after the system call. Original patch by Brian Brazil.

2085 ConfigParser.write.
2086
Daniel Stutzbach66c981b2010-08-31 20:29:39 +00002087- Issue #808164: Fixed socket.close to avoid references to globals, to
2088 avoid issues when socket.close is called from a __del__ method.
2089
Terry Reedyd2d2ae92010-11-11 23:22:19 +00002090- Issue #2986: difflib.SequenceMatcher gets a new parameter, autojunk, which
2091 can be set to False to turn off the previously undocumented 'popularity'
2092 heuristic. Patch by Terry Reedy and Eli Bendersky
2093
Senthil Kumaran7e8fd5e2010-08-26 06:20:13 +00002094- Issue #8797: urllib2 does a retry for Basic Authentication failure instead of
2095 falling into recursion.
2096
R. David Murray7c4bf552010-08-25 01:45:57 +00002097- Issue #1194222: email.utils.parsedate now returns RFC2822 compliant four
2098 character years even if the message contains RFC822 two character years.
2099
Daniel Stutzbach91287322010-08-24 21:09:30 +00002100- Issue #8750: Fixed MutableSet's methods to correctly handle

Raymond Hettinger917bba12010-08-22 08:01:58 +00002111- Issue #9214: Set operations on KeysView or ItemsView in the collections
2112 module now correctly return a set. (Patch by Eli Bendersky.)
2113
Antoine Pitrou3ebaed62010-08-21 19:17:25 +00002114- Issue #9617: Signals received during a low-level write operation aren't
2115 ignored by the buffered IO layer anymore.
2116
Benjamin Peterson52c36052010-08-21 03:03:22 +00002117- Issue #2521: Use weakrefs on for caching in the abc module, so that classes
2118 are not held onto after they are deleted elsewhere.
2119
Raymond Hettingera54b2da2010-08-17 19:03:06 +00002120- Issue #9626: the view methods for collections.OrderedDict() were returning
2121 the unordered versions inherited from dict. Those methods are now
2122 overridden to provide ordered views.

2127
Antoine Pitroue1436d12010-08-12 15:25:51 +00002128- Issue #7467: when reading a file from a ZIP archive, its CRC is checked
2129 and a BadZipfile error is raised if it doesn't match (as used to be the
2130 case in Python 2.5 and earlier).
2131
Antoine Pitroucb4f47c2010-08-11 13:40:17 +00002132- Issue #9550: a BufferedReader could issue an additional read when the
2133 original read request had been satisfied, which could block indefinitely
2134 when the underlying raw IO channel was e.g. a socket. Report and original
2135 patch by Jason V. Miller.
2136
Fred Drake0a1fa0e2010-08-10 13:09:54 +00002137- Issue #9551: Don't raise TypeError when setting the value to None for

Senthil Kumarane677ecf2010-08-08 11:56:31 +00002155- Fix Issue8280 - urllib2's Request method will remove fragements in the url.
2156 This is how it is supposed to work, wget and curl do the same. Previous
2157 behavior was wrong.

2165 the option character for the added 'h/help' option if prefix_chars
2166 does not contain a '-', instead of raising an error.
2167

2528 E.g.: '\xf1\x80AB'.decode('utf-8', 'replace') now returns u'\ufffdAB' and
2529 replaces with U+FFFD only the start byte ('\xf1') and the continuation byte

Mark Dickinsond2f3e3f2010-05-05 22:23:58 +00002886 (Optimization was unintentionally turned on in gcc --with-pydebug builds in
2887 2.7 beta1 as a result of the issue #1628484 fix, combined with autoconf's
2888 strange choice of default CFLAGS produced by AC_PROG_CC for gcc.)

2908Core and Builtins
2909-----------------
2910
Philip Jenveyaebbaeb2010-04-06 23:24:45 +00002911- Issue #7301: Add environment variable $PYTHONWARNINGS.
2912
Benjamin Peterson3a1dfa22010-04-06 21:50:00 +00002913- Issue #8329: Don't return the same lists from select.select when no fds are
2914 changed.
2915
Georg Brandlfee0f442010-05-22 21:26:21 +00002916- Issue #8259: ``1L << (2**31)`` no longer produces an 'outrageous shift error'
Mark Dickinson82791672010-04-06 16:47:55 +00002917 on 64-bit machines. The shift count for either left or right shift is
2918 permitted to be up to sys.maxsize.
2919
Benjamin Peterson4ceeeb02010-04-03 22:48:51 +00002920- Ensure that tokenization of identifiers is not affected by locale.
2921
Georg Brandlfee0f442010-05-22 21:26:21 +00002922- Issue #1222585: Added LDCXXSHARED for C++ support. Patch by Arfrever.
Tarek Ziadé00002952010-04-03 08:37:59 +00002923
Benjamin Peterson1c7c11e2010-04-03 01:28:57 +00002924- Raise a TypeError when trying to delete a T_STRING_INPLACE struct member.
2925
Georg Brandlfee0f442010-05-22 21:26:21 +00002926- Issue #7994: Issue a PendingDeprecationWarning if object.__format__ is called
2927 with a non-empty format string. This is an effort to future-proof user
2928 code. If a derived class does not currently implement __format__ but later
2929 adds its own __format__, it would most likely break user code that had
Antoine Pitrou01a196a2011-01-02 20:05:11 +00002930 supplied a format string. This will be changed to a DeprecationWarning in
Georg Brandlfee0f442010-05-22 21:26:21 +00002931 Python 3.3 and it will be an error in Python 3.4.
Eric Smithd44b2fc2010-04-02 12:30:56 +00002932
Antoine Pitroua57df2c2010-03-31 21:32:15 +00002933- Issue #8268: Old-style classes (not just instances) now support weak

2942 arguments to a function correct.
2943
Benjamin Peterson0dee9c12010-03-17 20:41:42 +00002944- Issue #8164: Don't allow lambda functions to have a docstring.
2945
Victor Stinner66644262010-03-10 22:30:19 +00002946- Issue #3137: Don't ignore errors at startup, especially a keyboard interrupt
Georg Brandlba83f822010-03-14 09:50:54 +00002947 (SIGINT). If an error occurs while importing the site module, the error is
2948 printed and Python exits. Initialize the GIL before importing the site
Victor Stinner66644262010-03-10 22:30:19 +00002949 module.

Benjamin Peterson76a23c12010-04-04 23:23:22 +00002962- Issue #8310: Allow dis to examine new style classes.
2963
Georg Brandlfee0f442010-05-22 21:26:21 +00002964- Issue #8257: The Decimal construct now accepts a float instance directly,
2965 converting that float to a Decimal of equal value:
Mark Dickinson8a950712010-04-03 15:47:46 +00002966
2967 >>> Decimal(1.1)
2968 Decimal('1.100000000000000088817841970012523233890533447265625')
2969
Raymond Hettinger34c35b22010-04-03 10:22:00 +00002970- collections.Counter() now supports a subtract() method.
2971
Georg Brandlfee0f442010-05-22 21:26:21 +00002972- The functools module now has a total_ordering() class decorator to simplify
2973 the specification of rich comparisons.
Raymond Hettingera551f312010-04-04 18:34:45 +00002974
Georg Brandlfee0f442010-05-22 21:26:21 +00002975- The functools module also adds cmp_to_key() as a tool to transition old-style
2976 comparison functions to new-style key-functions.
Raymond Hettingera551f312010-04-04 18:34:45 +00002977
Georg Brandlfee0f442010-05-22 21:26:21 +00002978- Issue #8294: The Fraction constructor now accepts Decimal and float instances
2979 directly.
Mark Dickinson7c63eee2010-04-02 22:27:36 +00002980
Georg Brandlfee0f442010-05-22 21:26:21 +00002981- Issue #7279: Comparisons involving a Decimal signaling NaN now signal
2982 InvalidOperation instead of returning False. (Comparisons involving a quiet
2983 NaN are unchanged.) Also, Decimal quiet NaNs are now hashable; Decimal
2984 signaling NaNs remain unhashable.
Mark Dickinsone096e822010-04-02 10:17:07 +00002985
Georg Brandlfee0f442010-05-22 21:26:21 +00002986- Issue #2531: Comparison operations between floats and Decimal instances now
2987 return a result based on the numeric values of the operands; previously they
2988 returned an arbitrary result based on the relative ordering of id(float) and
2989 id(Decimal).
Mark Dickinson99d80962010-04-02 08:53:22 +00002990
Barry Warsawf7f2d6f2010-03-31 21:07:16 +00002991- Issue #8233: When run as a script, py_compile.py optionally takes a single
Georg Brandlfee0f442010-05-22 21:26:21 +00002992 argument `-` which tells it to read files to compile from stdin. Each line is
2993 read on demand and the named file is compiled immediately. (Original patch by
2994 Piotr Ożarowski).
Barry Warsawf7f2d6f2010-03-31 21:07:16 +00002995
Georg Brandlfee0f442010-05-22 21:26:21 +00002996- Issue #3135: Add ``inspect.getcallargs()``, which binds arguments to a

Florent Xicluna58b65662010-03-30 16:29:03 +00002999- Backwards incompatible change: Unicode codepoints line tabulation (0x0B) and
3000 form feed (0x0C) are now considered linebreaks, as specified in Unicode
Georg Brandlfee0f442010-05-22 21:26:21 +00003001 Standard Annex #14. See issue #7643. http://www.unicode.org/reports/tr14/
Florent Xicluna22b24382010-03-30 08:24:06 +00003002
Georg Brandlfee0f442010-05-22 21:26:21 +00003003- Comparisons using one of <, <=, >, >= between a complex instance and a
3004 Fractions instance now raise TypeError instead of returning True/False. This
3005 makes Fraction <=> complex comparisons consistent with int <=> complex, float
3006 <=> complex, and complex <=> complex comparisons.
Mark Dickinson9588d992010-03-27 11:14:37 +00003007
Michael Foorde6410c52010-03-29 20:04:23 +00003008- Addition of ``WeakSet`` to the ``weakref`` module.

Antoine Pitrou513d9ae2010-03-22 19:59:46 +00003017- Issue #7512: shutil.copystat() could raise an OSError when the filesystem
Georg Brandlfee0f442010-05-22 21:26:21 +00003018 didn't support chflags() (for example ZFS under FreeBSD). The error is now
3019 silenced.
Antoine Pitrou513d9ae2010-03-22 19:59:46 +00003020
Florent Xicluna9e7a4c92010-03-22 16:07:38 +00003021- Issue #7703: ctypes supports both buffer() and memoryview(). The former is

Vinay Sajipecfa08f2010-03-12 09:16:10 +00003061- Issue #8117: logging: Improved algorithm for computing initial rollover time
Georg Brandlfee0f442010-05-22 21:26:21 +00003062 for ``TimedRotatingFileHandler`` by using the modification time of an existing
3063 log file to compute the next rollover time. If the log file does not exist,
3064 the current time is used as the basis for the computation.
Vinay Sajip9098ee42010-03-12 06:01:21 +00003065

3115 the set of integer codes for which it was used differed between native packing
3116 and standard packing.)

3370 returning NULL. The macro now returns a statically allocated empty string
3371 instead.

Georg Brandlba83f822010-03-14 09:50:54 +00003424 file position when calling `truncate()`. It would previously change the file
3425 position to the given argument, which goes against the tradition of
Antoine Pitrouf3fa0742010-01-31 22:26:04 +00003426 ftruncate() and other truncation APIs. Patch by Pascal Chambon.
3427

3429 class used to represent files stored inside an archive. The new
3430 implementation is significantly faster and can be wrapped in a
3431 ``io.BufferedReader`` object for more speedups. It also solves an issue
3432 where interleaved calls to ``read()`` and ``readline()`` give wrong results.
3433 Patch by Nir Aides.

Benjamin Petersona43f34c2010-01-25 03:31:13 +00003442
Georg Brandlba83f822010-03-14 09:50:54 +00003443- Issue #7748: Since unicode values are supported for some metadata options in
3444 Distutils, the DistributionMetadata get_* methods will now return an utf-8
3445 encoded string for them. This ensures that the upload and register commands
3446 send the correct values to PyPI without any error.

Georg Brandlba83f822010-03-14 09:50:54 +00003717- Issue #7117: ``repr(x)`` for a float x returns a result based on the shortest
3718 decimal string that's guaranteed to round back to x under correct rounding
3719 (with round-half-to-even rounding mode). Previously it gave a string based on
3720 rounding x to 17 decimal digits. repr(x) for a complex number behaves
3721 similarly. On platforms where the correctly-rounded strtod and dtoa code is
3722 not supported (see below), repr is unchanged.
Mark Dickinsonb678de82009-11-19 18:41:49 +00003723
Georg Brandlba83f822010-03-14 09:50:54 +00003724- Issue #7117: On almost all platforms: float-to-string and string-to-float
3725 conversions within Python are now correctly rounded. Places these conversions
3726 occur include: str for floats and complex numbers; the float and complex
3727 constructors; old-style and new-style numeric formatting; serialization and
3728 deserialization of floats and complex numbers using marshal, pickle and json;
3729 parsing of float and imaginary literals in Python code; Decimal-to-float
3730 conversion.
Mark Dickinsonb678de82009-11-19 18:41:49 +00003731
Georg Brandlba83f822010-03-14 09:50:54 +00003732 The conversions use a Python-adapted version of David Gay's well-known dtoa.c,
3733 providing correctly-rounded strtod and dtoa C functions. This code is
3734 supported on Windows, and on Unix-like platforms using gcc, icc or suncc as
3735 the C compiler. There may be a small number of platforms on which correct
3736 operation of this code cannot be guaranteed, so the code is not used: notably,
3737 this applies to platforms where the C double format is not IEEE 754 binary64,
3738 and to platforms on x86 hardware where the x87 FPU is set to 64-bit precision
3739 and Python's configure script is unable to determine how to change the FPU
3740 precision. On these platforms conversions use the platform strtod and dtoa,
3741 as before.
Mark Dickinsonb678de82009-11-19 18:41:49 +00003742
Georg Brandlba83f822010-03-14 09:50:54 +00003743- Issue #7117: Backport round implementation from Python 3.x. ``round()`` now
3744 uses the correctly-rounded string <-> float conversions described above (when
3745 available), and so produces correctly rounded results that will display nicely
3746 under the float repr. There are two related small changes: (1) round now
3747 accepts any class with an ``__index__()`` method for its second argument (but
3748 no longer accepts floats for the second argument), and (2) an excessively
3749 large second integer argument (e.g., ``round(1.234, 10**100)``) no longer
3750 raises an exception.

Georg Brandlba83f822010-03-14 09:50:54 +00003897- Issue #5920: For ``float.__format__()``, change the behavior with the empty
3898 presentation type (that is, not one of 'e', 'f', 'g', or 'n') to be like 'g'
3899 but with at least one decimal point and with a default precision
3900 of 12. Previously, the behavior the same but with a default precision of 6.
3901 This more closely matches ``str()``, and reduces surprises when adding
3902 alignment flags to the empty presentation type. This also affects the new
3903 complex.__format__ in the same way.

Georg Brandlba83f822010-03-14 09:50:54 +00004043- Issue #1180193: When importing a module from a .pyc (or .pyo) file with an
4044 existing .py counterpart, override the co_filename attributes of all code
4045 objects if the original filename is obsolete (which can happen if the file has

4100
Georg Brandlba83f822010-03-14 09:50:54 +00004101- Issue #4233: Changed semantic of ``_fileio.FileIO``'s ``close()`` method on
4102 file objects with closefd=False. The file descriptor is still kept open but
4103 the file object behaves like a closed file. The ``FileIO`` object also got a
4104 new readonly attribute ``closefd``.

Benjamin Peterson399b1fe2008-10-25 02:53:28 +00004124- Using ``nonlocal`` as a variable name will now raise a Py3k SyntaxWarning

Georg Brandlba83f822010-03-14 09:50:54 +00004127- On windows, ``os.chdir()`` given unicode was not working if
4128 GetCurrentDirectoryW returned a path longer than MAX_PATH. (But It's doubtful
4129 this code path is really executed because I cannot move to such directory on
4130 win2k)

Georg Brandlba83f822010-03-14 09:50:54 +00004132- Issue #4069: When ``set.remove(element)`` is used with a set element, the
4133 element is temporarily replaced with an equivalent frozenset. But the
4134 eventual KeyError would always report the empty ``frozenset()`` as the missing
4135 key. Now it correctly refers to the initial element.

Walter Dörwalded960ac2009-05-03 22:36:33 +00004155- Issue #5108: Handle %s like %S and %R in PyUnicode_FromFormatV(): Call
4156 PyUnicode_DecodeUTF8() once, remember the result and output it in a second
4157 step. This avoids problems with counting UTF-8 bytes that ignores the effect
4158 of using the replace error handler in PyUnicode_DecodeUTF8().
4159
Walter Dörwald726ba8e2009-05-06 14:32:35 +00004160- Issue #3739: The unicode-internal encoder now reports the number of characters

Georg Brandlba83f822010-03-14 09:50:54 +00004163- Issue #2422: When compiled with the ``--with-valgrind`` option, the pymalloc

4165 gives improved memory leak detection when running under Valgrind, while taking
4166 advantage of pymalloc at other times.

5390 threads could return successfully while some Thread objects were still

5532
Amaury Forgeot d'Arc05e34492008-09-10 22:04:45 +00005533- Issue #3743: In a few places, PY_FORMAT_SIZE_T was incorrectly used with
5534 PyString_FromFormat or PyErr_Format to display size_t values. The macro
5535 PY_FORMAT_SIZE_T is designed to select the correct format for the OS
5536 ``printf`` function, whereas PyString_FromFormat has an independent
5537 implementation and uses "%zd" on all platforms for size_t values.
5538 This makes a difference on win64, where ``printf`` needs "%Id" to display
5539 64bit values.

Benjamin Peterson97179b02008-09-09 20:55:01 +00005541- Issue #3634: _weakref.ref(Exception).__init__() gave invalid return value on

5545 object; previously an int would be returned for small values. the __long__
5546 method is allowed to return either an int or a long, but the behaviour of

Antoine Pitroud4ae97b2008-08-29 18:39:48 +00005556 was correctly parsed but parsing of subsequent arguments failed.
5557
Vinay Sajip35e3b032008-09-01 14:33:59 +00005558- Issue #2534: speed up isinstance() and issubclass() by 50-70%, so as to
Antoine Pitrou0668c622008-08-26 22:42:08 +00005559 match Python 2.5 speed despite the __instancecheck__ / __subclasscheck__
5560 mechanism. In the process, fix a bug where isinstance() and issubclass(),
5561 when given a tuple of classes as second argument, were looking up
5562 __instancecheck__ / __subclasscheck__ on the tuple rather than on each
5563 type object.

Amaury Forgeot d'Arc293924b2008-09-02 23:19:56 +00005661- Issue #2975: When compiling several extension modules with Visual Studio 2008
5662 from the same python interpreter, some environment variables would grow
5663 without limit.
5664
Benjamin Peterson37346b22008-08-23 20:27:43 +00005665- Issue #3643: Added a few more checks to _testcapi to prevent segfaults by

Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00005702What's New in Python 2.6 beta 3?
5703================================
5704
Barry Warsaw07a4a382008-08-21 01:15:08 +00005705*Release date: 20-Aug-2008*
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00005706
5707Core and Builtins
5708-----------------
5709
Guido van Rossumf8402962008-08-20 15:01:50 +00005710- Issue #1878: Remove Py_TPFLAGS_HAVE_VERSION_TAG from
5711 Py_TPFLAGS_DEFAULT when not building the core. This means 3rd party
5712 extensions do not automatically benefit from the class attribute
5713 cache; they will have to explicitly add Py_TPFLAGS_HAVE_VERSION_TAG
5714 to their tp_flags field if they care. This is a backwards
5715 compatibility feature; in 3.0, all types will use the cache by
5716 default.
5717
Benjamin Petersonf647dc12008-08-20 01:27:30 +00005718- Keyword arguments can now follow starred arguments. (``f(a, *args,
5719 keyword=23)`` is now valid syntax.)
5720
Thomas Heller0ad5ae02008-08-19 19:25:04 +00005721- ctypes function pointers that are COM methods have a boolean True
5722 value again.
5723
Martin v. Löwisf91d46a2008-08-12 14:49:50 +00005724- Issue #3139: Make buffer-interface thread-safe wrt. PyArg_ParseTuple,
5725 by denying s# to parse objects that have a releasebuffer procedure,
5726 and introducing s*.
5727
Georg Brandl1e13ea92008-08-11 09:07:59 +00005728- Issue #3537: Fix an assertion failure when an empty but presized dict
5729 object was stored in the freelist.
5730
Mark Dickinsonb6467572008-08-04 21:30:09 +00005731- Issue #1481296: Make long(float('nan')) and int(float('nan')) raise
5732 ValueError consistently across platforms.
5733
Amaury Forgeot d'Arc39fd6722008-07-31 21:28:03 +00005734- Issue #3479: On platforms where sizeof(int) is smaller than sizeof(long)
5735 (64bit Unix, for example), unichr() would truncate its argument and return
5736 u'\x00' for unichr(2**32). Now it properly raises an OverflowError.
5737
Neal Norwitze7d8be82008-07-31 17:17:14 +00005738- Apply security patches from Apple.
5739
Amaury Forgeot d'Arc246daed2008-07-31 00:42:16 +00005740- Issue #2542: Now that issubclass() may call arbitrary code, ensure that
5741 PyErr_ExceptionMatches returns 0 when an exception occurs there.
5742
Antoine Pitrou92f82162008-07-25 22:22:08 +00005743- Issue #1819: function calls with several named parameters are now on
5744 average 35% faster (as measured by pybench).
5745
Amaury Forgeot d'Arce4921fe2008-07-21 22:00:38 +00005746- Issue #2378: An unexpected UnboundLocalError or NameError could appear when
5747 the python debugger steps into a class statement: the free variables (local
5748 variables defined in an outer scope) would be deleted from the outer scope.
5749
Gregory P. Smith0470bab2008-07-22 04:46:32 +00005750- Issue #2620: Overflow checking when allocating or reallocating memory
5751 was not always being done properly in some python types and extension
5752 modules. PyMem_MALLOC, PyMem_REALLOC, PyMem_NEW and PyMem_RESIZE have
5753 all been updated to perform better checks and places in the code that
5754 would previously leak memory on the error path when such an allocation
5755 failed have been fixed.
5756
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00005757Library
5758-------
5759
Hirokazu Yamamoto838c79f2008-08-20 13:14:07 +00005760- Issue #3612: Added some missing basic types in ctypes.wintypes.
5761
Benjamin Petersone977ad42008-08-20 01:42:01 +00005762- The methods ``is_in_tuple()``, ``is_vararg()``, and ``is_keywordarg()`` of
5763 symtable.Symbol have been deprecated for removal in 3.0 and the next release.
5764
Amaury Forgeot d'Arc351ffb82008-08-18 19:23:47 +00005765- Issue #2234: distutils failed for some versions of the cygwin compiler. The
5766 version reported by these tools does not necessarily follow the python
5767 version numbering scheme, so the module is less strict when parsing it.
5768
Nick Coghlanf70385a2008-08-18 12:42:46 +00005769- Issue #2235: Added Py3k warnings for types which will become unhashable
5770 under the stricter __hash__ inheritance rules in 3.0. Several types
5771 which did not meet the rules for hash invariants and were already
5772 unhashable in 3.0 have now been explicitly flagged as unhashable in
5773 2.6 as well (collections.Mapping, collections.Set, unittest.TestSuite,
5774 xml.dom.minidom.NamedNodeMap, numbers.Number, UserList.UserList)
5775
Brett Cannon88f801d2008-08-18 00:46:22 +00005776- Update __all__ for cookielib, csv, os, urllib2, and weakref to include things
5777 imported into the module but exposed as part of the module's API.
5778
Brett Cannon7b96f072008-08-18 00:41:11 +00005779- Remove an unneeded import of abc.ABCMeta from 'inspect'.
5780
Brett Cannon46225e72008-08-18 00:36:52 +00005781- Remove unneeded imports of 'sys' and 'warnings' from 'io'.
5782
Brett Cannon25c9d6a2008-08-17 22:10:11 +00005783- Remove unneeded imports of 'warnings' from shelve, filecmp, and dummy_thread.
5784
Hirokazu Yamamoto41a81eb2008-08-17 13:10:46 +00005785- Issue #3575: Incremental decoder's decode function now takes bytearray
5786 by using 's*' instead of 't#'.
5787
Mark Dickinson3e4caeb2009-02-21 20:27:01 +00005788- Issue #2222: Fixed reference leak when occurred os.rename()
Hirokazu Yamamoto7f30a682008-08-17 09:46:56 +00005789 fails unicode conversion on 2nd parameter. (windows only)
5790
Georg Brandl222e2082010-08-01 22:27:39 +00005791- Issue #2464: urllib2 now supports a malformation in the URL received
Facundo Batista94f243a2008-08-17 03:38:39 +00005792 in a redirect.
5793
Brett Cannonabe423e2008-08-16 21:47:07 +00005794- Silence the DeprecationWarning raised when importing mimetools in
Brett Cannon721b1452008-08-16 22:00:27 +00005795 BaseHTTPServer, cgi (and rfc822), httplib.
Brett Cannonabe423e2008-08-16 21:47:07 +00005796
Facundo Batistaeb90b782008-08-16 14:44:07 +00005797- Issue #2776: fixed small issue when handling an URL with double slash
5798 after a 302 response in the case of not going through a proxy.
5799
Antoine Pitroub90a8be2008-08-15 21:03:21 +00005800- Issue #2676: in the email package, content-type parsing was hanging on
5801 pathological input because of quadratic or exponential behaviour of a
5802 regular expression.
5803
Antoine Pitrou11ec65d2008-08-14 21:04:30 +00005804- Issue #3476: binary buffered reading through the new "io" library is now
5805 thread-safe.
5806
Brett Cannonbf3157b2008-08-14 05:00:03 +00005807- Silence the DeprecationWarning of rfc822 when it is imported by mimetools
5808 since mimetools itself is deprecated. Because modules are cached, all
5809 subsequent imports of rfc822 will not raise a visible DeprecationWarning.
5810
Antoine Pitrou9fcd4b32008-08-11 17:21:36 +00005811- Issue #3134: shutil referenced undefined WindowsError symbol.
5812
Robert Schuppenies14646332008-08-10 11:01:53 +00005813- Issue #1342811: Fix leak in Tkinter.Menu.delete. Commands associated to
5814 menu entries were not deleted.
5815
Brett Cannon83e81842008-08-09 23:30:55 +00005816- Copied the implementation of reduce() to _functools.reduce() to have a
5817 version that did not raise a DeprecationWarning under -3.
5818
Antoine Pitrou76b8bee2008-08-09 17:27:23 +00005819- Issue #3205: When iterating over a BZ2File fails allocating memory, raise
5820 a MemoryError rather than silently stop the iteration.
5821
Guido van Rossum59ce9012008-08-09 14:55:34 +00005822- Issue #3487: sre "bytecode" validator. Passing invalid "re-bytecode"
5823 to _sre.compile() will now be rejected. This should not affect anybody
5824 since the re.compile() function never generates invalid re-bytecode.
5825
Skip Montanaroa032bf42008-08-08 22:52:51 +00005826- Issue #3436: Make csv.DictReader's fieldnames attribute a property so that
5827 upon first access it can be automatically initialized from the csv file if
5828 it wasn't initialized during instantiation.
5829
Brett Cannon3aa2a492008-08-06 22:28:09 +00005830- Issue #2338: Create imp.reload() to help with transitioning to Python 3.0 as
5831 the reload() built-in has been removed.
5832
Brett Cannon7e30b672008-08-04 21:52:25 +00005833- Changed code in the following modules/packages to remove warnings raised
Brett Cannonc1b76e42008-08-09 23:06:16 +00005834 while running under the ``-3`` flag: aifc, asynchat, asyncore, bdb, bsddb,

5842 raised an AttributeError.
5843
Benjamin Peterson01a24322008-07-28 23:35:27 +00005844- Issue #2523: Fix quadratic behaviour when read()ing a binary file without
Antoine Pitroude781a42008-08-09 12:43:23 +00005845 asking for a specific length. This problem only affected files opened
5846 using the new "io" module, not the built-in open() function.
Benjamin Peterson01a24322008-07-28 23:35:27 +00005847
Mark Dickinsonfe84cce2008-07-27 06:39:07 +00005848- Issue #3449: Update decimal module to use most recent specification
5849 (v. 1.68) and tests (v. 2.58) from IBM.
5850
Georg Brandl222e2082010-08-01 22:27:39 +00005851- Issue #3437: Bug fix in robotparser parsing of Allow: lines.

5855
Georg Brandlf9efabb2008-07-23 15:16:45 +00005856- Deprecate the "ast" parser function aliases.
5857
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00005858- Issue #3120: On 64-bit Windows the subprocess module was truncating handles.
5859
5860- Issue #3303: Fix a crash in locale.strcoll() when calling it with
5861 invalid arguments.
5862
5863- Issue #3302: Fix several crashes when calling locale's gettext functions
5864 with None arguments.
5865
5866- Issue #3389: Allow resolving dotted names for handlers in logging
5867 configuration files.
5868

5870
Antoine Pitrou5fdfa3e2008-07-25 19:42:26 +00005871- Issue #3394: zipfile.writestr sets external attributes when passed a
5872 file name rather than a ZipInfo instance, so files are extracted with
5873 mode 0600 rather than 000 under Unix.
5874
Gregory P. Smitha36f8fe2008-08-04 00:13:29 +00005875- Issue #1857: subprocess.Popen.poll gained an additional _deadstate keyword
5876 argument in python 2.5, this broke code that subclassed Popen to include its
5877 own poll method. Fixed my moving _deadstate to an _internal_poll method.

5885-------------
5886
Nick Coghlan6e8fef02008-08-18 13:14:22 +00005887- Issue #2235: the C API function PyObject_HashNotImplemented and its
5888 interaction with the tp_hash slot (added in 2.6b2) are now documented
5889
Nick Coghlan2a0c2b12008-08-04 12:47:17 +00005890- Issue #643841: The language reference now provides more detailed
5891 coverage of the lookup process for special methods. The disclaimers
5892 regarding lack of coverage of new-style classes have also been
5893 removed, since the coverage is now fairly reasonable.

Raymond Hettingere3ae6552008-06-20 04:18:15 +00005896What's New in Python 2.6 beta 2?
5897================================
5898
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00005899*Release date: 17-Jul-2008*
5900
Raymond Hettingere3ae6552008-06-20 04:18:15 +00005901Core and Builtins
5902-----------------
5903
Georg Brandl3e483f62008-07-16 22:57:41 +00005904- Issue #3156: Fix inconsistent behavior of the bytearray type: all
5905 its methods now allow for items objects that can be converted to
5906 an integer using operator.index().
5907
Mark Dickinson64b7e502008-07-16 09:40:03 +00005908- Issue #3360: Fix incorrect parsing of '020000000000.0', which
5909 produced a ValueError instead of giving the correct float.
5910
Eric Smitha5fa5a22008-07-16 00:11:49 +00005911- Issue #3083: Add alternate (#) formatting for bin, oct, hex output
5912 for str.format(). This adds the prefix 0b, 0o, or 0x, respectively.
5913
Mark Dickinson7103aa42008-07-15 19:08:33 +00005914- Issue #3008: the float type has a new instance method 'float.hex'
5915 and a new class method 'float.fromhex' to convert floating-point
5916 numbers to and from hexadecimal strings, respectively.
5917
Nick Coghlan6d6bd442008-07-15 15:40:22 +00005918- Issue #2235: __hash__ is once again inherited by default. To allow
5919 collections.Hashable to remain meaningful in the presence of the
5920 default hash implementation (object.__hash__), it is now possible
5921 to explicit block inheritance of hash by setting __hash__=None at
5922 the Python level, or tp_hash=PyObject_HashNotImplemented at the C
5923 level.
5924
Nick Coghlanb028f502008-07-13 14:52:36 +00005925- Issue #3221: Issue a RuntimeWarning instead of raising SystemError if
5926 the parent module cannot be found while performing an absolute import.
5927 This means that an incorrectly defined __package__ attribute will
5928 now only prevent relative imports in that module rather than causing
5929 all imports from that module to fail.
5930
Nick Coghlan14ff9942008-07-08 14:21:42 +00005931- Issue #2517: Allow unicode messages in Exceptions again by correctly
5932 bypassing the instance dictionary when looking up __unicode__ on
5933 new-style classes.
5934
Amaury Forgeot d'Arcbdd941f2008-07-01 20:38:04 +00005935- Issue #3242: Fix a crash inside the print statement, if sys.stdout is
5936 set to a custom object whose write() method happens to install
5937 another file in sys.stdout.
5938
Amaury Forgeot d'Arc1f40c8a2008-06-30 22:42:40 +00005939- Issue #3088: Corrected a race condition in classes derived from
5940 threading.local: the first member set by a thread could be saved in
5941 another thread's dictionary.
5942
Mark Dickinson1ec2fcd2008-06-20 14:53:43 +00005943- Issue #3004: Minor change to slice.indices(): the start and stop
5944 arguments are now treated identically, making the behaviour easier
5945 to describe and understand. For example, slice(None, -10,
5946 1).indices(9) now returns (0, 0, 1) instead of (0, -1, 1), and
5947 slice(None, 10, -1).indices(10) returns (9, 9, -1) instead of (9,
5948 10, -1).
5949
Georg Brandl278fc502008-07-19 12:46:12 +00005950- Issue #3219: Calling a function with repeated keyword arguments,

Georg Brandl5cc774e2008-06-11 20:28:06 +00006402 PPC64 and x86_64 support in one binary).
Ronald Oussoren5640ce22008-06-05 12:58:24 +00006403
6404 This is controlled by the configure argument ``--with-universal-archs``:
6405

6407
6408 - ``--with-universal-archs=32-bit``: install 2-way universal, 32-bit (the default)
6409
6410 - ``--with-universal-archs=64-bit``: install 2-way universal, 64-bit

6451 two handlers that derive the same default base class.

Georg Brandl3ee81df2008-05-17 18:14:43 +00006464- Issue #1631171: Re-implement the 'warnings' module in C (the
6465 original Python code has been kept as backup). This will allow for
6466 using the 'warning's machinery in such places as the parser where
6467 use of pure Python code is not possible. Both the ``showarning()``
6468 and ``formatwarning()`` gain an optional 'line' argument which is
6469 not called by default for backwards-compatibility reasons. Setting
6470 ``warnings.showwarning()`` to an implementation that lacks support
6471 for the ``line`` argument will raise a DeprecationWarning.

Gregory P. Smithd59fefb2008-04-22 08:11:33 +00006496- The getpass module has been improved on Unix. It now uses /dev/tty

Georg Brandl3ee81df2008-05-17 18:14:43 +00006534- Issue #2550: The approach used by client/server code for obtaining
6535 ports to listen on in network-oriented tests has been refined in an
6536 effort to facilitate running multiple instances of the entire
6537 regression test suite in parallel without issue.
6538 test_support.bind_port() has been fixed such that it will always
6539 return a unique port -- which wasn't always the case with the
6540 previous implementation, especially if socket options had been set
6541 that affected address reuse (i.e. SO_REUSEADDR, SO_REUSEPORT). The
6542 new implementation of bind_port() will actually raise an exception
6543 if it is passed an AF_INET/SOCK_STREAM socket with either the
6544 SO_REUSEADDR or SO_REUSEPORT socket option set. Furthermore, if
6545 available, bind_port() will set the SO_EXCLUSIVEADDRUSE option on
6546 the socket it's been passed. This currently only applies to
6547 Windows. This option prevents any other sockets from binding to the
6548 host/port we've bound to, thus removing the possibility of the
6549 'non-deterministic' behaviour, as Microsoft puts it, that occurs
6550 when a second SOCK_STREAM socket binds and accepts to a host/port
6551 that's already been bound by another socket. The optional preferred
6552 port parameter to bind_port() has been removed. Under no
6553 circumstances should tests be hard coding ports!
6554
6555 test_support.find_unused_port() has also been introduced, which will
6556 pass a temporary socket object to bind_port() in order to obtain an
6557 unused port. The temporary socket object is then closed and
6558 deleted, and the port is returned. This method should only be used
6559 for obtaining an unused port in order to pass to an external program
6560 (i.e. the -accept [port] argument to openssl's s_server mode) or as
6561 a parameter to a server-oriented class that doesn't give you direct
6562 access to the underlying socket used.
6563
6564 Finally, test_support.HOST has been introduced, which should be used
6565 for the host argument of any relevant socket calls (i.e. bind and
6566 connect).
Trent Nelsone41b0062008-04-08 23:47:30 +00006567
6568 The following tests were updated to following the new conventions:
Georg Brandl3ee81df2008-05-17 18:14:43 +00006569 test_socket, test_smtplib, test_asyncore, test_ssl, test_httplib,
Trent Nelsone41b0062008-04-08 23:47:30 +00006570 test_poplib, test_ftplib, test_telnetlib, test_socketserver,
6571 test_asynchat and test_socket_ssl.
6572
Georg Brandl3ee81df2008-05-17 18:14:43 +00006573 It is now possible for multiple instances of the regression test
6574 suite to run in parallel without issue.

Eric Smitha73fbe72008-02-23 03:09:44 +00006853- Added the future_builtins module, which contains hex() and oct().
6854 These are the PEP 3127 version of these functions, designed to be
6855 compatible with the hex() and oct() builtins from Python 3.0. They
6856 differ slightly in their output formats from the existing, unchanged
6857 Python 2.6 builtins. The expected usage of the future_builtins
6858 module is:
6859 from future_builtins import hex, oct
6860
Eric Smith7ef40bf2008-02-20 23:34:22 +00006861- Issue #1600: Modifed PyOS_ascii_formatd to use at most 2 digit
6862 exponents for exponents with absolute value < 100. Follows C99
6863 standard. This is a change on Windows, which would use 3 digits.
6864 Also, added 'n' to the formats that PyOS_ascii_formatd understands,
6865 so that any alterations it does to the resulting string will be
6866 available in stringlib/formatter.h (for float.__format__).
6867
Eric Smith5a3c1352008-02-19 13:21:56 +00006868- Implemented PEP 3101, Advanced String Formatting. This adds a new
6869 builtin format(); a format() method for str and unicode; a
6870 __format__() method to object, str, unicode, int, long, float, and
6871 datetime; the class string.Formatter; and the C API
6872 PyObject_Format().
6873
Georg Brandl3ee81df2008-05-17 18:14:43 +00006874- Fixed several potential crashes, all caused by specially crafted
6875 __del__ methods exploiting objects in temporarily inconsistent
6876 state.
Amaury Forgeot d'Arc632fad32008-02-16 20:55:24 +00006877
Vinay Sajipb7edfc42008-04-02 21:10:23 +00006878- Issue #2115: Important speedup in setting __slot__ attributes. Also
Georg Brandl3ee81df2008-05-17 18:14:43 +00006879 prevent a possible crash: an Abstract Base Class would try to access
6880 a slot on a registered virtual subclass.
Amaury Forgeot d'Arc60d6c7f2008-02-15 21:22:45 +00006881

Georg Brandl3ee81df2008-05-17 18:14:43 +00006885- Clear all free lists during a gc.collect() of the highest generation
6886 in order to allow pymalloc to free more arenas. Python may give back
6887 memory to the OS earlier.
Christian Heimes3b718a72008-02-14 12:47:33 +00006888
Georg Brandl3ee81df2008-05-17 18:14:43 +00006889- Issue #2045: Fix an infinite recursion triggered when printing a
6890 subclass of collections.defaultdict, if its default_factory is set
6891 to a bound method.
Amaury Forgeot d'Arcb01aa432008-02-08 00:56:02 +00006892
Christian Heimesf75dbef2008-02-08 00:11:31 +00006893- Fixed a minor memory leak in dictobject.c. The content of the free
6894 list was not freed on interpreter shutdown.
6895
Georg Brandl21e99f42010-03-07 15:23:59 +00006896- Limit free list of method and built-in function objects to 256
Georg Brandl3ee81df2008-05-17 18:14:43 +00006897 entries each.
Christian Heimes6075a822008-02-06 12:44:34 +00006898
Georg Brandl3ee81df2008-05-17 18:14:43 +00006899- Patch #1953: Added ``sys._compact_freelists()`` and the C API
6900 functions ``PyInt_CompactFreeList`` and ``PyFloat_CompactFreeList``
Christian Heimes422051a2008-02-04 18:00:12 +00006901 to compact the internal free lists of pre-allocted ints and floats.
6902
Georg Brandl3ee81df2008-05-17 18:14:43 +00006903- Issue #1983: Fixed return type of fork(), fork1() and forkpty()
6904 calls. Python expected the return type int but the fork familie
6905 returns pi_t.
Christian Heimes951cc0f2008-01-31 23:08:23 +00006906
Georg Brandl3ee81df2008-05-17 18:14:43 +00006907- Issue #1678380: Fix a bug that identifies 0j and -0j when they

Georg Brandl3ee81df2008-05-17 18:14:43 +00006919- Patch #1473257: generator objects gain a gi_code attribute. This is
6920 the same object as the func_code attribute of the function that
6921 produced the generator.
Georg Brandl0cdf9a32008-01-26 14:14:20 +00006922
Georg Brandl3ee81df2008-05-17 18:14:43 +00006923- Issue #1920: "while 0" statements were completely removed by the
6924 compiler, even in the presence of an "else" clause, which is
6925 supposed to be run when the condition is false. Now the compiler
6926 correctly emits bytecode for the "else" suite.
Amaury Forgeot d'Arc31eaafe2008-01-24 22:59:25 +00006927
Guido van Rossumeead05f2008-01-24 18:21:02 +00006928- A few crashers fixed: weakref_in_del.py (issue #1377858);
6929 loosing_dict_ref.py (issue #1303614, test67.py);
6930 borrowed_ref_[34].py (not in tracker).
6931
Vinay Sajipd7cf32e2008-01-24 12:43:33 +00006932- Issue #1069410: The "can't load dll" message box on Windows is
Christian Heimesb2302ba2008-01-23 17:15:06 +00006933 suppressed while an extension is loaded by calling SetErrorMode in
6934 dynload_win.c. The error is still reported properly.
6935
Georg Brandl3ee81df2008-05-17 18:14:43 +00006936- Issue #1915: Python compiles with --enable-unicode=no again. However
Christian Heimes082c9b02008-01-23 14:20:50 +00006937 several extension methods and modules do not work without unicode
6938 support.
6939
Georg Brandl26543b12008-01-21 18:36:51 +00006940- Issue #1882: when compiling code from a string, encoding cookies in the
6941 second line of code were not always recognized correctly.
6942
Georg Brandl14404b62008-01-19 19:27:05 +00006943- Issue #1679: "0x" was taken as a valid integer literal.
6944
Georg Brandl6caad7d2008-01-26 14:19:22 +00006945- Issue #1865: ``bytes`` as an alias for ``str`` and b"" as an alias "" were
Christian Heimes288e89a2008-01-18 18:24:07 +00006946 added.
6947
Christian Heimesc94e2b52008-01-14 04:13:37 +00006948- sys.float_info / PyFloat_GetInfo: The floating point information
6949 object was converted from a dict to a specialized structseq object.
6950
Georg Brandl3ee81df2008-05-17 18:14:43 +00006951- Patch #1816: Added sys.flags structseq. It exposes the status of
6952 most command line arguments and PYTHON* environment variables.
Christian Heimesf31b69f2008-01-14 03:42:48 +00006953
Georg Brandl3ee81df2008-05-17 18:14:43 +00006954- Objects/structseq.c: Implemented new structseq representation. The

Georg Brandl3ee81df2008-05-17 18:14:43 +00006980 and INF. float("nan"), float("inf") and float("-inf") now work on
6981 every platform with IEEE 754 semantics.
Christian Heimes0a8143f2007-12-18 23:22:54 +00006982
Georg Brandl3ee81df2008-05-17 18:14:43 +00006983- Compiler now generates simpler and faster code for dictionary
6984 literals. The oparg for BUILD_MAP now indicates an estimated
6985 dictionary size. There is a new opcode, STORE_MAP, for adding
6986 entries to the dictionary.

Georg Brandl3ee81df2008-05-17 18:14:43 +00007015- Patch #1739468: Directories and zipfiles containing a __main__.py
7016 file can now be directly executed by passing their name to the
7017 interpreter. The directory/zipfile is automatically inserted as the
7018 first entry in sys.path.

Georg Brandl3ee81df2008-05-17 18:14:43 +00007020- Issue #1265: Fix a problem with sys.settrace, if the tracing
7021 function uses a generator expression when at the same time the
7022 executed code is closing a paused generator.
Amaury Forgeot d'Arc0d75f092007-11-13 21:54:28 +00007023
Raymond Hettinger1760c8a2007-11-08 02:52:43 +00007024- sets and frozensets now have an isdisjoint() method.

7029
Georg Brandl21e99f42010-03-07 15:23:59 +00007030- The enumerate() built-in function is no longer bounded to sequences
Georg Brandl3ee81df2008-05-17 18:14:43 +00007031 smaller than LONG_MAX. Formerly, it raised an OverflowError. Now,
7032 automatically shifts from ints to longs.
Raymond Hettinger8f669372007-10-03 21:18:11 +00007033
Georg Brandl3ee81df2008-05-17 18:14:43 +00007034- Issue #1686386: Tuple's tp_repr did not take into account the
7035 possibility of having a self-referential tuple, which is possible
7036 from C code. Nor did object's tp_str consider that a type's tp_str
7037 could do something that could lead to an inifinite recursion.
7038 Py_ReprEnter() and Py_EnterRecursiveCall(), respectively, fixed the
7039 issues.
Brett Cannon0b14f242007-09-30 19:45:10 +00007040
Georg Brandl3ee81df2008-05-17 18:14:43 +00007041- Issue #1164: It was possible to trigger deadlock when using the
7042 'print' statement to write to a file since the GIL was not released
7043 as needed. Now PyObject_Print() does the right thing along with
7044 various tp_print implementations of the built-in types and those in
7045 the collections module.
Brett Cannon01531592007-09-17 03:28:34 +00007046
Georg Brandl3ee81df2008-05-17 18:14:43 +00007047- Issue #1147: Exceptions were directly allowing string exceptions in

7049 allowed.

Brett Cannona0c05512007-09-10 21:38:27 +00007053
Brett Cannon1e534b52007-09-07 04:18:30 +00007054- Issue #1202533: Fix infinite recursion calls triggered by calls to
Georg Brandl3ee81df2008-05-17 18:14:43 +00007055 PyObject_Call() never calling back out to Python code to trigger
7056 recursion depth updates/checks. Required the creation of a static
7057 RuntimeError instance in case normalizing an exception put the
7058 recursion check value past its limit. Fixes crashers
7059 infinite_rec_(1|2|4|5).py.
Brett Cannon1e534b52007-09-07 04:18:30 +00007060

Neal Norwitz0ac60192007-05-27 04:08:54 +00007074- Add new attribute names for function objects. All the func_* become
Georg Brandl3ee81df2008-05-17 18:14:43 +00007075 __*__ attributes. (Some already existed, e.g., __doc__ and
7076 __name__.)
Neal Norwitz0ac60192007-05-27 04:08:54 +00007077
Neal Norwitz8b2bfbc2007-05-23 06:35:32 +00007078- Add -3 option to the interpreter to warn about features that are
7079 deprecated and will be changed/removed in Python 3.0.
7080
Georg Brandl2134e752007-05-21 20:34:16 +00007081- Patch #1686487: you can now pass any mapping after '**' in function
7082 calls.
7083
Collin Winter62903052007-05-18 23:11:24 +00007084- except clauses may now be spelled either "except E, target:" or
Georg Brandl3ee81df2008-05-17 18:14:43 +00007085 "except E as target:". This is to provide forwards compatibility
7086 with Python 3.0.

Vinay Sajip8549ce32007-05-06 17:53:37 +00007093- When __slots__ are set to a unicode string, make it work the same as
Neal Norwitzcbd9ee62007-04-14 05:25:50 +00007094 setting a plain string, ie don't expand to single letter identifiers.
7095
Raymond Hettinger13936692007-04-11 18:40:58 +00007096- Request #1191699: Slices can now be pickled.
7097
Raymond Hettinger4db5fe92007-04-12 04:10:00 +00007098- Request #1193128: str.translate() now allows a None argument for
7099 translations that only remove characters without re-mapping the
7100 remaining characters.
7101
Georg Brandl5cb76c12007-03-21 09:00:39 +00007102- Patch #1682205: a TypeError while unpacking an iterable is no longer

7106
Guido van Rossum143b5642007-03-23 04:58:42 +00007107- Bug #1683368: The object.__init__() and object.__new__() methods are
7108 now stricter in rejecting excess arguments. The only time when
7109 either allows excess arguments is when it is not overridden and the
7110 other one is. For backwards compatibility, when both are
7111 overridden, it is a deprecation warning (for now; maybe a Py3k
Guido van Rossum234b1ff2007-03-23 19:39:01 +00007112 warning later). Also, type.__init__() insists on the same signature
7113 as supported by type.__new__().
Guido van Rossum143b5642007-03-23 04:58:42 +00007114
Georg Brandl3ee81df2008-05-17 18:14:43 +00007115- Patch #1675423: PyComplex_AsCComplex() now tries to convert an
7116 object to complex using its __complex__() method before falling back
7117 to the __float__() method. Therefore, the functions in the cmath
7118 module now can operate on objects that define a __complex__()
7119 method.
Georg Brandl2b869942007-03-17 16:08:45 +00007120
Georg Brandl3ee81df2008-05-17 18:14:43 +00007121- Patch #1623563: allow __class__ assignment for classes with
7122 __slots__. The old and the new class are still required to have the
7123 same slot names.

7129 ``object.__reduce_ex__()`` is called with an object that is faking
7130 its type.
Žiga Seilnacht20f43d32007-03-15 11:44:55 +00007131
Georg Brandl3ee81df2008-05-17 18:14:43 +00007132- Patch #1680015: Don't modify __slots__ tuple if it contains an

7136
Georg Brandl7b9c5552007-03-12 14:30:05 +00007137- Bug #1678647: write a newline after printing an exception in any
7138 case, even when converting the value to a string failed.
7139
Georg Brandl871f1bc2007-03-12 13:17:36 +00007140- The dir() function has been extended to call the __dir__() method on
Georg Brandl3ee81df2008-05-17 18:14:43 +00007141 its argument, if it exists. If not, it will work like before. This
7142 allows customizing the output of dir() in the presence of a
7143 __getattr__().

Georg Brandl3ee81df2008-05-17 18:14:43 +00007151- Patch #1491866: change the complex() constructor to allow
7152 parthensized forms. This means complex(repr(x)) now works instead of
7153 raising a ValueError.
Collin Wintere38051d2007-03-09 20:33:07 +00007154
Georg Brandlaa2321b2007-03-07 00:40:28 +00007155- Patch #703779: unset __file__ in __main__ after running a file. This
Georg Brandl3ee81df2008-05-17 18:14:43 +00007156 makes the filenames the warning module prints much more sensible
7157 when a PYTHONSTARTUP file is used.

Georg Brandl0fca97a2007-03-05 22:28:08 +00007170- Patch #1674228: when assigning a slice (old-style), check for the
7171 sq_ass_slice instead of the sq_slice slot.
7172
Georg Brandl3ee81df2008-05-17 18:14:43 +00007173- When printing an unraisable error, don't print exceptions. before
7174 the name. This duplicates the behavior whening normally printing
7175 exceptions.

7800 TestCase and TestSuite subclasses (not instances) are no longer
7801 accepted in TestSuite.addTest(). This should cause no

7803 -- the failure just occurred later, with a more cumbersome
7804 exception.

Georg Brandl3ee81df2008-05-17 18:14:43 +00008085- Issue #829951: In the smtplib module, SMTP.starttls() now complies
8086 with RFC 3207 and forgets any knowledge obtained from the server not
8087 obtained from the TLS negotiation itself. Patch contributed by Bill
8088 Fenner.
Gregory P. Smith2b3ba582008-01-17 08:03:17 +00008089
Georg Brandl3ee81df2008-05-17 18:14:43 +00008090- Issue #1339: The smtplib.SMTP class has been refactored a bit such
Gregory P. Smithbde4ae42008-01-17 08:35:49 +00008091 that the SMTP.starttls() caller no longer needs to call ehlo()
8092 beforehand. SMTP.starttls() now raises an exception of the server
Georg Brandl3ee81df2008-05-17 18:14:43 +00008093 does not claim to support starttls. Adds the
8094 SMTP.ehlo_or_helo_if_needed() method. Patch contributed by Bill

8175 complex, tuple, list, dict, set, and frozenset. Formerly, it would
8176 silently miscode subclasses of those types. Now, it raises a
8177 ValueError instead.
Raymond Hettinger12e94202007-11-07 01:13:09 +00008178

Georg Brandl3ee81df2008-05-17 18:14:43 +00008193 time so that opening a database previously created with the DB_DUP
8194 or DB_DUPSORT flag set will keep the proper behavior on subsequent
8195 opens. Specifically: dictionary assignment to a DB object will
8196 replace all values for a given key when the database allows
8197 duplicate values. DB users should use DB.put(k, v) when they want
8198 to store duplicates; not DB[k] = v.
Gregory P. Smithec10a4a2007-11-05 02:32:26 +00008199

8205 characters with ASCII value less than 32. Also, it correctly quotes
8206 dots only if they occur on a single line, as opposed to the previous
8207 behavior of quoting dots if they are the second character of any
8208 line.
Georg Brandl4aef7272007-03-13 22:49:43 +00008209

Raymond Hettingerdc1d1ba2007-11-07 02:45:46 +00008477- Add a FAST_LOOPS build option that speeds-up looping by trading away
Georg Brandl3ee81df2008-05-17 18:14:43 +00008478 periodic threadstate and signal checking in tight loops. By
8479 default, this option is turned-off. It should only be enabled in
8480 debugged, performance critical applications.

8536 #ifndef block.
Christian Heimes5b970ad2008-02-06 13:33:44 +00008537
Georg Brandl3ee81df2008-05-17 18:14:43 +00008538- ``PySet_Add()`` can now modify a newly created frozenset. Similarly
8539 to ``PyTuple_SetItem``, it can be used to populate a brand new
8540 frozenset; but it does not steal a reference to the added item.

8552
Georg Brandl3ee81df2008-05-17 18:14:43 +00008553- Issue #1521: On 64bit platforms, using PyArgs_ParseTuple with the t#
8554 of w# format code incorrectly truncated the length to an int, even
8555 when PY_SSIZE_T_CLEAN is set. The str.decode method used to return
8556 incorrect results with huge strings.
Georg Brandl6caad7d2008-01-26 14:19:22 +00008557
Georg Brandl3ee81df2008-05-17 18:14:43 +00008558- Issue #1629: Renamed Py_Size, Py_Type and Py_Refcnt to Py_SIZE,

8578
8579- Make _PyGILState_NoteThreadState() static, it was not used anywhere
8580 outside of pystate.c and should not be necessary.
8581
Georg Brandl3ee81df2008-05-17 18:14:43 +00008582- ``PyImport_Import`` and ``PyImport_ImportModule`` now always do
8583 absolute imports. In earlier versions they might have used relative
8584 imports under some conditions.
Christian Heimes000a0742008-01-03 22:16:32 +00008585
Georg Brandl3ee81df2008-05-17 18:14:43 +00008586- Added case insensitive comparison methods ``PyOS_stricmp(char*,
8587 char*)`` and ``PyOS_strnicmp(char*, char*, Py_ssize_t)``.
Christian Heimes000a0742008-01-03 22:16:32 +00008588
Georg Brandl3ee81df2008-05-17 18:14:43 +00008589- Bug #1542693: remove semi-colon at end of PyImport_ImportModuleEx

Georg Brandl3ee81df2008-05-17 18:14:43 +00008614- Removed the macfs module. It had been deprecated since Python 2.5.
8615 This lead to the deprecation of macostools.touched() as it relied
8616 solely on macfs and was a no-op under OS X.
