Mark Dickinsondbbed042011-09-19 16:38:08 +010041- Issue #12973: Fix overflow checks that invoked undefined behaviour in
42 int.__pow__. These overflow checks were causing int.__pow__ to produce

45 in list_repeat (listobject.c) and islice_next (itertoolsmodule.c). These

Antoine Pitrou16166452011-07-12 22:04:20 +020057- Issue #12149: Update the method cache after a type's dictionnary gets
58 cleared by the garbage collector. This fixes a segfault when an instance

265
Ned Deily87e82bb2011-06-28 19:52:59 -0700266- Issue #9516: On Mac OS X, change Distutils to no longer globally attempt to
267 check or set the MACOSX_DEPLOYMENT_TARGET environment variable for the
268 interpreter process. This could cause failures in non-Distutils subprocesses
269 and was unreliable since tests or user programs could modify the interpreter
270 environment after Distutils set it. Instead, have Distutils set the the
271 deployment target only in the environment of each build subprocess. It is
272 still possible to globally override the default by setting
273 MACOSX_DEPLOYMENT_TARGET before launching the interpreter; its value must be
274 greater or equal to the default value, the value with which the interpreter
275 was built.

Barry Warsawc5643282011-07-19 17:06:30 -0400303- sys.setcheckinterval() now updates the current ticker count as well as
304 updating the check interval, so if the user decreases the check interval,
305 the ticker doesn't have to wind down to zero from the old starting point
306 before the new interval takes effect. And if the user increases the
307 interval, it makes sure the new limit takes effect right away rather have an
308 early task switch before recognizing the new interval.

1198 fix various SSLSocket methods to raise socket.error rather than an
1199 unhelpful TypeError when called on an unconnected socket. Original patch
1200 by Andrew Bennetts.

1209
Raymond Hettinger20397532010-09-12 02:11:45 +00001210- Issue #9825: removed __del__ from the definition of collections.OrderedDict.
1211 This prevents user-created self-referencing ordered dictionaries from
1212 becoming permanently uncollectable GC garbage. The downside is that
1213 removing __del__ means that the internal doubly-linked list has to wait for
1214 GC collection rather than freeing memory immediately when the refcnt drops
1215 to zero.
1216

1223 to fetch the original errno, or to filter timeout errors. Now the
1224 original error is re-raised.

R. David Murray7c4bf552010-08-25 01:45:57 +00001246- Issue #1194222: email.utils.parsedate now returns RFC2822 compliant four
1247 character years even if the message contains RFC822 two character years.

1262
Antoine Pitrou3ebaed62010-08-21 19:17:25 +00001263- Issue #9617: Signals received during a low-level write operation aren't
1264 ignored by the buffered IO layer anymore.
1265

1268
Raymond Hettingera54b2da2010-08-17 19:03:06 +00001269- Issue #9626: the view methods for collections.OrderedDict() were returning

1283 when the underlying raw IO channel was e.g. a socket. Report and original
1284 patch by Jason V. Miller.

Georg Brandlfee0f442010-05-22 21:26:21 +00002034- Issue #8625: Turn off optimization in ``--with-pydebug`` builds with gcc.
Mark Dickinsond2f3e3f2010-05-05 22:23:58 +00002035 (Optimization was unintentionally turned on in gcc --with-pydebug builds in
2036 2.7 beta1 as a result of the issue #1628484 fix, combined with autoconf's
2037 strange choice of default CFLAGS produced by AC_PROG_CC for gcc.)

2057Core and Builtins
2058-----------------
2059
Philip Jenveyaebbaeb2010-04-06 23:24:45 +00002060- Issue #7301: Add environment variable $PYTHONWARNINGS.
2061
Benjamin Peterson3a1dfa22010-04-06 21:50:00 +00002062- Issue #8329: Don't return the same lists from select.select when no fds are
2063 changed.
2064
Georg Brandlfee0f442010-05-22 21:26:21 +00002065- Issue #8259: ``1L << (2**31)`` no longer produces an 'outrageous shift error'
Mark Dickinson82791672010-04-06 16:47:55 +00002066 on 64-bit machines. The shift count for either left or right shift is
2067 permitted to be up to sys.maxsize.
2068
Benjamin Peterson4ceeeb02010-04-03 22:48:51 +00002069- Ensure that tokenization of identifiers is not affected by locale.
2070
Georg Brandlfee0f442010-05-22 21:26:21 +00002071- Issue #1222585: Added LDCXXSHARED for C++ support. Patch by Arfrever.
Tarek Ziadé00002952010-04-03 08:37:59 +00002072
Benjamin Peterson1c7c11e2010-04-03 01:28:57 +00002073- Raise a TypeError when trying to delete a T_STRING_INPLACE struct member.
2074
Georg Brandlfee0f442010-05-22 21:26:21 +00002075- Issue #7994: Issue a PendingDeprecationWarning if object.__format__ is called
2076 with a non-empty format string. This is an effort to future-proof user
2077 code. If a derived class does not currently implement __format__ but later
2078 adds its own __format__, it would most likely break user code that had
Antoine Pitrou01a196a2011-01-02 20:05:11 +00002079 supplied a format string. This will be changed to a DeprecationWarning in
Georg Brandlfee0f442010-05-22 21:26:21 +00002080 Python 3.3 and it will be an error in Python 3.4.
Eric Smithd44b2fc2010-04-02 12:30:56 +00002081
Antoine Pitroua57df2c2010-03-31 21:32:15 +00002082- Issue #8268: Old-style classes (not just instances) now support weak

2094
Victor Stinner66644262010-03-10 22:30:19 +00002095- Issue #3137: Don't ignore errors at startup, especially a keyboard interrupt
Georg Brandlba83f822010-03-14 09:50:54 +00002096 (SIGINT). If an error occurs while importing the site module, the error is
2097 printed and Python exits. Initialize the GIL before importing the site
Victor Stinner66644262010-03-10 22:30:19 +00002098 module.

Benjamin Peterson76a23c12010-04-04 23:23:22 +00002111- Issue #8310: Allow dis to examine new style classes.
2112
Georg Brandlfee0f442010-05-22 21:26:21 +00002113- Issue #8257: The Decimal construct now accepts a float instance directly,
2114 converting that float to a Decimal of equal value:
Mark Dickinson8a950712010-04-03 15:47:46 +00002115
2116 >>> Decimal(1.1)
2117 Decimal('1.100000000000000088817841970012523233890533447265625')
2118
Raymond Hettinger34c35b22010-04-03 10:22:00 +00002119- collections.Counter() now supports a subtract() method.
2120
Georg Brandlfee0f442010-05-22 21:26:21 +00002121- The functools module now has a total_ordering() class decorator to simplify
2122 the specification of rich comparisons.
Raymond Hettingera551f312010-04-04 18:34:45 +00002123
Georg Brandlfee0f442010-05-22 21:26:21 +00002124- The functools module also adds cmp_to_key() as a tool to transition old-style
2125 comparison functions to new-style key-functions.
Raymond Hettingera551f312010-04-04 18:34:45 +00002126
Georg Brandlfee0f442010-05-22 21:26:21 +00002127- Issue #8294: The Fraction constructor now accepts Decimal and float instances
2128 directly.
Mark Dickinson7c63eee2010-04-02 22:27:36 +00002129
Georg Brandlfee0f442010-05-22 21:26:21 +00002130- Issue #7279: Comparisons involving a Decimal signaling NaN now signal
2131 InvalidOperation instead of returning False. (Comparisons involving a quiet
2132 NaN are unchanged.) Also, Decimal quiet NaNs are now hashable; Decimal
2133 signaling NaNs remain unhashable.
Mark Dickinsone096e822010-04-02 10:17:07 +00002134
Georg Brandlfee0f442010-05-22 21:26:21 +00002135- Issue #2531: Comparison operations between floats and Decimal instances now
2136 return a result based on the numeric values of the operands; previously they
2137 returned an arbitrary result based on the relative ordering of id(float) and
2138 id(Decimal).
Mark Dickinson99d80962010-04-02 08:53:22 +00002139
Barry Warsawf7f2d6f2010-03-31 21:07:16 +00002140- Issue #8233: When run as a script, py_compile.py optionally takes a single
Georg Brandlfee0f442010-05-22 21:26:21 +00002141 argument `-` which tells it to read files to compile from stdin. Each line is
2142 read on demand and the named file is compiled immediately. (Original patch by
2143 Piotr Ożarowski).
Barry Warsawf7f2d6f2010-03-31 21:07:16 +00002144
Georg Brandlfee0f442010-05-22 21:26:21 +00002145- Issue #3135: Add ``inspect.getcallargs()``, which binds arguments to a

Florent Xicluna58b65662010-03-30 16:29:03 +00002148- Backwards incompatible change: Unicode codepoints line tabulation (0x0B) and
2149 form feed (0x0C) are now considered linebreaks, as specified in Unicode
Georg Brandlfee0f442010-05-22 21:26:21 +00002150 Standard Annex #14. See issue #7643. http://www.unicode.org/reports/tr14/
Florent Xicluna22b24382010-03-30 08:24:06 +00002151
Georg Brandlfee0f442010-05-22 21:26:21 +00002152- Comparisons using one of <, <=, >, >= between a complex instance and a
2153 Fractions instance now raise TypeError instead of returning True/False. This
2154 makes Fraction <=> complex comparisons consistent with int <=> complex, float
2155 <=> complex, and complex <=> complex comparisons.
Mark Dickinson9588d992010-03-27 11:14:37 +00002156

2165
Antoine Pitrou513d9ae2010-03-22 19:59:46 +00002166- Issue #7512: shutil.copystat() could raise an OSError when the filesystem
Georg Brandlfee0f442010-05-22 21:26:21 +00002167 didn't support chflags() (for example ZFS under FreeBSD). The error is now
2168 silenced.
Antoine Pitrou513d9ae2010-03-22 19:59:46 +00002169
Florent Xicluna9e7a4c92010-03-22 16:07:38 +00002170- Issue #7703: ctypes supports both buffer() and memoryview(). The former is

Georg Brandlfee0f442010-05-22 21:26:21 +00002211 for ``TimedRotatingFileHandler`` by using the modification time of an existing
2212 log file to compute the next rollover time. If the log file does not exist,
2213 the current time is used as the basis for the computation.

Mark Dickinson4846a8e2010-04-03 14:05:10 +00002254- Issue #8300: When passing a non-integer argument to struct.pack with any
2255 integer format code, struct.pack first attempts to convert the non-integer

Georg Brandlba83f822010-03-14 09:50:54 +00002259- Issue #1530559: When passing a non-integer argument to struct.pack with *any*
2260 integer format code (one of 'bBhHiIlLqQ'), struct.pack attempts to use the
2261 argument's __int__ method to convert to an integer before packing. It also
Georg Brandlfee0f442010-05-22 21:26:21 +00002262 produces a DeprecationWarning in this case. (In Python 2.6, the behaviour was
2263 inconsistent: __int__ was used for some integer codes but not for others, and
2264 the set of integer codes for which it was used differed between native packing
2265 and standard packing.)

2479 original CWD is saved in ``test.test_support.SAVEDCWD``. Thanks to Florent
2480 Xicluna who helped with the patch.

2497 and read operations on write-only file objects. On Windows, the system C
Georg Brandlba83f822010-03-14 09:50:54 +00002498 library would return a bogus result; on Solaris, it was possible to crash the

Georg Brandlba83f822010-03-14 09:50:54 +00002517- Issue #7561: Operations on empty bytearrays (such as ``int(bytearray())``)
2518 could crash in many places because of the ``PyByteArray_AS_STRING()`` macro
2519 returning NULL. The macro now returns a statically allocated empty string
2520 instead.

2530 strings,
2531 (2) a crash in dtoa.c that occurred in debug builds when parsing certain long
2532 numeric strings corresponding to subnormal values,
2533 (3) a memory leak for some values large enough to cause overflow, and
2534 (4) a number of flaws that could lead to incorrectly rounded results.

Antoine Pitroud840e512010-02-04 20:20:18 +00002565- Issue #4772: Raise a ValueError when an unknown Bluetooth protocol is
Georg Brandlba83f822010-03-14 09:50:54 +00002566 specified, rather than fall through to AF_PACKET (in the ``socket`` module).
Antoine Pitroud840e512010-02-04 20:20:18 +00002567 Also, raise ValueError rather than TypeError when an unknown TIPC address
2568 type is specified. Patch by Brian Curtin.

Antoine Pitrouf3fa0742010-01-31 22:26:04 +00002572- Issue #6939: Fix file I/O objects in the `io` module to keep the original
Georg Brandlba83f822010-03-14 09:50:54 +00002573 file position when calling `truncate()`. It would previously change the file
2574 position to the given argument, which goes against the tradition of
Antoine Pitrouf3fa0742010-01-31 22:26:04 +00002575 ftruncate() and other truncation APIs. Patch by Pascal Chambon.
2576
Georg Brandlba83f822010-03-14 09:50:54 +00002577- Issue #7610: Reworked implementation of the internal ``zipfile.ZipExtFile``
2578 class used to represent files stored inside an archive. The new
2579 implementation is significantly faster and can be wrapped in a
2580 ``io.BufferedReader`` object for more speedups. It also solves an issue
2581 where interleaved calls to ``read()`` and ``readline()`` give wrong results.
2582 Patch by Nir Aides.

Benjamin Petersona43f34c2010-01-25 03:31:13 +00002591
Georg Brandlba83f822010-03-14 09:50:54 +00002592- Issue #7748: Since unicode values are supported for some metadata options in
2593 Distutils, the DistributionMetadata get_* methods will now return an utf-8
2594 encoded string for them. This ensures that the upload and register commands
2595 send the correct values to PyPI without any error.

Amaury Forgeot d'Arcd7288712009-12-01 21:51:04 +00002851

Ronald Oussoren315cd0c2009-11-19 16:25:21 +00002865
Georg Brandlba83f822010-03-14 09:50:54 +00002866- Issue #7117: ``repr(x)`` for a float x returns a result based on the shortest
2867 decimal string that's guaranteed to round back to x under correct rounding
2868 (with round-half-to-even rounding mode). Previously it gave a string based on
2869 rounding x to 17 decimal digits. repr(x) for a complex number behaves
2870 similarly. On platforms where the correctly-rounded strtod and dtoa code is
2871 not supported (see below), repr is unchanged.
Mark Dickinsonb678de82009-11-19 18:41:49 +00002872
Georg Brandlba83f822010-03-14 09:50:54 +00002873- Issue #7117: On almost all platforms: float-to-string and string-to-float
2874 conversions within Python are now correctly rounded. Places these conversions
2875 occur include: str for floats and complex numbers; the float and complex
2876 constructors; old-style and new-style numeric formatting; serialization and
2877 deserialization of floats and complex numbers using marshal, pickle and json;
2878 parsing of float and imaginary literals in Python code; Decimal-to-float
2879 conversion.
Mark Dickinsonb678de82009-11-19 18:41:49 +00002880
Georg Brandlba83f822010-03-14 09:50:54 +00002881 The conversions use a Python-adapted version of David Gay's well-known dtoa.c,
2882 providing correctly-rounded strtod and dtoa C functions. This code is
2883 supported on Windows, and on Unix-like platforms using gcc, icc or suncc as
2884 the C compiler. There may be a small number of platforms on which correct
2885 operation of this code cannot be guaranteed, so the code is not used: notably,
2886 this applies to platforms where the C double format is not IEEE 754 binary64,
2887 and to platforms on x86 hardware where the x87 FPU is set to 64-bit precision
2888 and Python's configure script is unable to determine how to change the FPU
2889 precision. On these platforms conversions use the platform strtod and dtoa,
2890 as before.
Mark Dickinsonb678de82009-11-19 18:41:49 +00002891
Georg Brandlba83f822010-03-14 09:50:54 +00002892- Issue #7117: Backport round implementation from Python 3.x. ``round()`` now
2893 uses the correctly-rounded string <-> float conversions described above (when
2894 available), and so produces correctly rounded results that will display nicely
2895 under the float repr. There are two related small changes: (1) round now
2896 accepts any class with an ``__index__()`` method for its second argument (but
2897 no longer accepts floats for the second argument), and (2) an excessively
2898 large second integer argument (e.g., ``round(1.234, 10**100)``) no longer
2899 raises an exception.

Georg Brandlba83f822010-03-14 09:50:54 +00003046- Issue #5920: For ``float.__format__()``, change the behavior with the empty
3047 presentation type (that is, not one of 'e', 'f', 'g', or 'n') to be like 'g'
3048 but with at least one decimal point and with a default precision
3049 of 12. Previously, the behavior the same but with a default precision of 6.
3050 This more closely matches ``str()``, and reduces surprises when adding
3051 alignment flags to the empty presentation type. This also affects the new
3052 complex.__format__ in the same way.

Georg Brandlba83f822010-03-14 09:50:54 +00003192- Issue #1180193: When importing a module from a .pyc (or .pyo) file with an
3193 existing .py counterpart, override the co_filename attributes of all code

3249
Georg Brandlba83f822010-03-14 09:50:54 +00003250- Issue #4233: Changed semantic of ``_fileio.FileIO``'s ``close()`` method on
3251 file objects with closefd=False. The file descriptor is still kept open but
3252 the file object behaves like a closed file. The ``FileIO`` object also got a
3253 new readonly attribute ``closefd``.

Benjamin Peterson399b1fe2008-10-25 02:53:28 +00003273- Using ``nonlocal`` as a variable name will now raise a Py3k SyntaxWarning

Georg Brandlba83f822010-03-14 09:50:54 +00003276- On windows, ``os.chdir()`` given unicode was not working if
3277 GetCurrentDirectoryW returned a path longer than MAX_PATH. (But It's doubtful
3278 this code path is really executed because I cannot move to such directory on
3279 win2k)

Georg Brandlba83f822010-03-14 09:50:54 +00003281- Issue #4069: When ``set.remove(element)`` is used with a set element, the
3282 element is temporarily replaced with an equivalent frozenset. But the
3283 eventual KeyError would always report the empty ``frozenset()`` as the missing

Walter Dörwalded960ac2009-05-03 22:36:33 +00003304- Issue #5108: Handle %s like %S and %R in PyUnicode_FromFormatV(): Call
3305 PyUnicode_DecodeUTF8() once, remember the result and output it in a second
3306 step. This avoids problems with counting UTF-8 bytes that ignores the effect
3307 of using the replace error handler in PyUnicode_DecodeUTF8().
3308
Walter Dörwald726ba8e2009-05-06 14:32:35 +00003309- Issue #3739: The unicode-internal encoder now reports the number of characters

3311
Georg Brandlba83f822010-03-14 09:50:54 +00003312- Issue #2422: When compiled with the ``--with-valgrind`` option, the pymalloc

3314 gives improved memory leak detection when running under Valgrind, while taking
3315 advantage of pymalloc at other times.

Georg Brandlba83f822010-03-14 09:50:54 +00004538 leak-chasing test runs give sensible results. The previous method of reaping
4539 threads could return successfully while some Thread objects were still
4540 referenced. This also introduces a new private function: ``thread._count()``.

Guilherme Polo7f146ab2009-06-21 17:22:50 +00004557- Issue #5450: Moved tests involving loading tk from Lib/test/test_tcl to
4558 Lib/lib-tk/test/test_tkinter/test_loadtk. With this, these tests demonstrate
Georg Brandlba83f822010-03-14 09:50:54 +00004559 the same behaviour as test_ttkguionly (and now also test_tk) which is to skip
4560 the tests if DISPLAY is defined but can't be used.

4566 import both normal and optimised versions of modules. test_heapq and
4567 test_warnings have been adjusted to use it, tests for other modules with both
4568 C and Python implementations in the stdlib can be adjusted to use it over
4569 time.

4681
Amaury Forgeot d'Arc05e34492008-09-10 22:04:45 +00004682- Issue #3743: In a few places, PY_FORMAT_SIZE_T was incorrectly used with
4683 PyString_FromFormat or PyErr_Format to display size_t values. The macro
4684 PY_FORMAT_SIZE_T is designed to select the correct format for the OS
4685 ``printf`` function, whereas PyString_FromFormat has an independent
4686 implementation and uses "%zd" on all platforms for size_t values.
4687 This makes a difference on win64, where ``printf`` needs "%Id" to display
4688 64bit values.

Benjamin Peterson97179b02008-09-09 20:55:01 +00004690- Issue #3634: _weakref.ref(Exception).__init__() gave invalid return value on

4694 object; previously an int would be returned for small values. the __long__
4695 method is allowed to return either an int or a long, but the behaviour of

Antoine Pitroud4ae97b2008-08-29 18:39:48 +00004705 was correctly parsed but parsing of subsequent arguments failed.

Vinay Sajip35e3b032008-09-01 14:33:59 +00004707- Issue #2534: speed up isinstance() and issubclass() by 50-70%, so as to
Antoine Pitrou0668c622008-08-26 22:42:08 +00004708 match Python 2.5 speed despite the __instancecheck__ / __subclasscheck__
4709 mechanism. In the process, fix a bug where isinstance() and issubclass(),
4710 when given a tuple of classes as second argument, were looking up
4711 __instancecheck__ / __subclasscheck__ on the tuple rather than on each
4712 type object.

Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00004851What's New in Python 2.6 beta 3?
4852================================
4853
Barry Warsaw07a4a382008-08-21 01:15:08 +00004854*Release date: 20-Aug-2008*
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00004855
4856Core and Builtins
4857-----------------
4858
Guido van Rossumf8402962008-08-20 15:01:50 +00004859- Issue #1878: Remove Py_TPFLAGS_HAVE_VERSION_TAG from
4860 Py_TPFLAGS_DEFAULT when not building the core. This means 3rd party
4861 extensions do not automatically benefit from the class attribute
4862 cache; they will have to explicitly add Py_TPFLAGS_HAVE_VERSION_TAG
4863 to their tp_flags field if they care. This is a backwards
4864 compatibility feature; in 3.0, all types will use the cache by
4865 default.
4866
Benjamin Petersonf647dc12008-08-20 01:27:30 +00004867- Keyword arguments can now follow starred arguments. (``f(a, *args,
4868 keyword=23)`` is now valid syntax.)
4869
Thomas Heller0ad5ae02008-08-19 19:25:04 +00004870- ctypes function pointers that are COM methods have a boolean True
4871 value again.
4872
Martin v. Löwisf91d46a2008-08-12 14:49:50 +00004873- Issue #3139: Make buffer-interface thread-safe wrt. PyArg_ParseTuple,
4874 by denying s# to parse objects that have a releasebuffer procedure,
4875 and introducing s*.
4876
Georg Brandl1e13ea92008-08-11 09:07:59 +00004877- Issue #3537: Fix an assertion failure when an empty but presized dict
4878 object was stored in the freelist.
4879
Mark Dickinsonb6467572008-08-04 21:30:09 +00004880- Issue #1481296: Make long(float('nan')) and int(float('nan')) raise
4881 ValueError consistently across platforms.
4882
Amaury Forgeot d'Arc39fd6722008-07-31 21:28:03 +00004883- Issue #3479: On platforms where sizeof(int) is smaller than sizeof(long)
4884 (64bit Unix, for example), unichr() would truncate its argument and return
4885 u'\x00' for unichr(2**32). Now it properly raises an OverflowError.
4886
Neal Norwitze7d8be82008-07-31 17:17:14 +00004887- Apply security patches from Apple.
4888
Amaury Forgeot d'Arc246daed2008-07-31 00:42:16 +00004889- Issue #2542: Now that issubclass() may call arbitrary code, ensure that
4890 PyErr_ExceptionMatches returns 0 when an exception occurs there.
4891
Antoine Pitrou92f82162008-07-25 22:22:08 +00004892- Issue #1819: function calls with several named parameters are now on
4893 average 35% faster (as measured by pybench).
4894
Amaury Forgeot d'Arce4921fe2008-07-21 22:00:38 +00004895- Issue #2378: An unexpected UnboundLocalError or NameError could appear when
4896 the python debugger steps into a class statement: the free variables (local
4897 variables defined in an outer scope) would be deleted from the outer scope.
4898
Gregory P. Smith0470bab2008-07-22 04:46:32 +00004899- Issue #2620: Overflow checking when allocating or reallocating memory
4900 was not always being done properly in some python types and extension
4901 modules. PyMem_MALLOC, PyMem_REALLOC, PyMem_NEW and PyMem_RESIZE have
4902 all been updated to perform better checks and places in the code that
4903 would previously leak memory on the error path when such an allocation
4904 failed have been fixed.

4907-------
4908
Hirokazu Yamamoto838c79f2008-08-20 13:14:07 +00004909- Issue #3612: Added some missing basic types in ctypes.wintypes.
4910
Benjamin Petersone977ad42008-08-20 01:42:01 +00004911- The methods ``is_in_tuple()``, ``is_vararg()``, and ``is_keywordarg()`` of
4912 symtable.Symbol have been deprecated for removal in 3.0 and the next release.
4913
Amaury Forgeot d'Arc351ffb82008-08-18 19:23:47 +00004914- Issue #2234: distutils failed for some versions of the cygwin compiler. The
4915 version reported by these tools does not necessarily follow the python
4916 version numbering scheme, so the module is less strict when parsing it.
4917
Nick Coghlanf70385a2008-08-18 12:42:46 +00004918- Issue #2235: Added Py3k warnings for types which will become unhashable
4919 under the stricter __hash__ inheritance rules in 3.0. Several types
4920 which did not meet the rules for hash invariants and were already
4921 unhashable in 3.0 have now been explicitly flagged as unhashable in
4922 2.6 as well (collections.Mapping, collections.Set, unittest.TestSuite,
4923 xml.dom.minidom.NamedNodeMap, numbers.Number, UserList.UserList)
4924
Brett Cannon88f801d2008-08-18 00:46:22 +00004925- Update __all__ for cookielib, csv, os, urllib2, and weakref to include things
4926 imported into the module but exposed as part of the module's API.
4927
Brett Cannon7b96f072008-08-18 00:41:11 +00004928- Remove an unneeded import of abc.ABCMeta from 'inspect'.
4929
Brett Cannon46225e72008-08-18 00:36:52 +00004930- Remove unneeded imports of 'sys' and 'warnings' from 'io'.
4931
Brett Cannon25c9d6a2008-08-17 22:10:11 +00004932- Remove unneeded imports of 'warnings' from shelve, filecmp, and dummy_thread.
4933
Hirokazu Yamamoto41a81eb2008-08-17 13:10:46 +00004934- Issue #3575: Incremental decoder's decode function now takes bytearray
4935 by using 's*' instead of 't#'.
4936
Mark Dickinson3e4caeb2009-02-21 20:27:01 +00004937- Issue #2222: Fixed reference leak when occurred os.rename()
Hirokazu Yamamoto7f30a682008-08-17 09:46:56 +00004938 fails unicode conversion on 2nd parameter. (windows only)
4939
Georg Brandl222e2082010-08-01 22:27:39 +00004940- Issue #2464: urllib2 now supports a malformation in the URL received
Facundo Batista94f243a2008-08-17 03:38:39 +00004941 in a redirect.
4942
Brett Cannonabe423e2008-08-16 21:47:07 +00004943- Silence the DeprecationWarning raised when importing mimetools in
Brett Cannon721b1452008-08-16 22:00:27 +00004944 BaseHTTPServer, cgi (and rfc822), httplib.
Brett Cannonabe423e2008-08-16 21:47:07 +00004945
Facundo Batistaeb90b782008-08-16 14:44:07 +00004946- Issue #2776: fixed small issue when handling an URL with double slash
4947 after a 302 response in the case of not going through a proxy.
4948
Antoine Pitroub90a8be2008-08-15 21:03:21 +00004949- Issue #2676: in the email package, content-type parsing was hanging on
4950 pathological input because of quadratic or exponential behaviour of a
4951 regular expression.
4952
Antoine Pitrou11ec65d2008-08-14 21:04:30 +00004953- Issue #3476: binary buffered reading through the new "io" library is now
4954 thread-safe.
4955
Brett Cannonbf3157b2008-08-14 05:00:03 +00004956- Silence the DeprecationWarning of rfc822 when it is imported by mimetools
4957 since mimetools itself is deprecated. Because modules are cached, all
4958 subsequent imports of rfc822 will not raise a visible DeprecationWarning.
4959
Antoine Pitrou9fcd4b32008-08-11 17:21:36 +00004960- Issue #3134: shutil referenced undefined WindowsError symbol.
4961
Robert Schuppenies14646332008-08-10 11:01:53 +00004962- Issue #1342811: Fix leak in Tkinter.Menu.delete. Commands associated to
4963 menu entries were not deleted.
4964
Brett Cannon83e81842008-08-09 23:30:55 +00004965- Copied the implementation of reduce() to _functools.reduce() to have a
4966 version that did not raise a DeprecationWarning under -3.
4967
Antoine Pitrou76b8bee2008-08-09 17:27:23 +00004968- Issue #3205: When iterating over a BZ2File fails allocating memory, raise
4969 a MemoryError rather than silently stop the iteration.
4970
Guido van Rossum59ce9012008-08-09 14:55:34 +00004971- Issue #3487: sre "bytecode" validator. Passing invalid "re-bytecode"
4972 to _sre.compile() will now be rejected. This should not affect anybody
4973 since the re.compile() function never generates invalid re-bytecode.
4974
Skip Montanaroa032bf42008-08-08 22:52:51 +00004975- Issue #3436: Make csv.DictReader's fieldnames attribute a property so that
4976 upon first access it can be automatically initialized from the csv file if
4977 it wasn't initialized during instantiation.
4978
Brett Cannon3aa2a492008-08-06 22:28:09 +00004979- Issue #2338: Create imp.reload() to help with transitioning to Python 3.0 as
4980 the reload() built-in has been removed.
4981
Brett Cannon7e30b672008-08-04 21:52:25 +00004982- Changed code in the following modules/packages to remove warnings raised
Brett Cannonc1b76e42008-08-09 23:06:16 +00004983 while running under the ``-3`` flag: aifc, asynchat, asyncore, bdb, bsddb,

Brett Cannon7e30b672008-08-04 21:52:25 +00004989
Lars Gustäbel727bd0b2008-08-02 11:26:39 +00004990- Issue #3039: Fix tarfile.TarFileCompat.writestr() which always
4991 raised an AttributeError.
4992
Benjamin Peterson01a24322008-07-28 23:35:27 +00004993- Issue #2523: Fix quadratic behaviour when read()ing a binary file without
Antoine Pitroude781a42008-08-09 12:43:23 +00004994 asking for a specific length. This problem only affected files opened
4995 using the new "io" module, not the built-in open() function.
Benjamin Peterson01a24322008-07-28 23:35:27 +00004996
Mark Dickinsonfe84cce2008-07-27 06:39:07 +00004997- Issue #3449: Update decimal module to use most recent specification
4998 (v. 1.68) and tests (v. 2.58) from IBM.
4999
Georg Brandl222e2082010-08-01 22:27:39 +00005000- Issue #3437: Bug fix in robotparser parsing of Allow: lines.
Skip Montanarof9ac43f2008-07-27 00:50:41 +00005001

Raymond Hettinger8c664e82008-07-25 18:43:33 +00005003 on a closed shelf.
5004
Georg Brandlf9efabb2008-07-23 15:16:45 +00005005- Deprecate the "ast" parser function aliases.
5006
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00005007- Issue #3120: On 64-bit Windows the subprocess module was truncating handles.
5008
5009- Issue #3303: Fix a crash in locale.strcoll() when calling it with
5010 invalid arguments.
5011
5012- Issue #3302: Fix several crashes when calling locale's gettext functions
5013 with None arguments.
5014
5015- Issue #3389: Allow resolving dotted names for handlers in logging
5016 configuration files.
5017

5019
Antoine Pitrou5fdfa3e2008-07-25 19:42:26 +00005020- Issue #3394: zipfile.writestr sets external attributes when passed a
5021 file name rather than a ZipInfo instance, so files are extracted with
5022 mode 0600 rather than 000 under Unix.
5023
Gregory P. Smitha36f8fe2008-08-04 00:13:29 +00005024- Issue #1857: subprocess.Popen.poll gained an additional _deadstate keyword
5025 argument in python 2.5, this broke code that subclassed Popen to include its
5026 own poll method. Fixed my moving _deadstate to an _internal_poll method.

5035
Nick Coghlan6e8fef02008-08-18 13:14:22 +00005036- Issue #2235: the C API function PyObject_HashNotImplemented and its
5037 interaction with the tp_hash slot (added in 2.6b2) are now documented
5038
Nick Coghlan2a0c2b12008-08-04 12:47:17 +00005039- Issue #643841: The language reference now provides more detailed
5040 coverage of the lookup process for special methods. The disclaimers
5041 regarding lack of coverage of new-style classes have also been
5042 removed, since the coverage is now fairly reasonable.

5047
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00005048*Release date: 17-Jul-2008*

Raymond Hettingere3ae6552008-06-20 04:18:15 +00005050Core and Builtins
5051-----------------
5052
Georg Brandl3e483f62008-07-16 22:57:41 +00005053- Issue #3156: Fix inconsistent behavior of the bytearray type: all
5054 its methods now allow for items objects that can be converted to
5055 an integer using operator.index().
5056
Mark Dickinson64b7e502008-07-16 09:40:03 +00005057- Issue #3360: Fix incorrect parsing of '020000000000.0', which
5058 produced a ValueError instead of giving the correct float.
5059
Eric Smitha5fa5a22008-07-16 00:11:49 +00005060- Issue #3083: Add alternate (#) formatting for bin, oct, hex output
5061 for str.format(). This adds the prefix 0b, 0o, or 0x, respectively.
5062
Mark Dickinson7103aa42008-07-15 19:08:33 +00005063- Issue #3008: the float type has a new instance method 'float.hex'
5064 and a new class method 'float.fromhex' to convert floating-point
5065 numbers to and from hexadecimal strings, respectively.
5066
Nick Coghlan6d6bd442008-07-15 15:40:22 +00005067- Issue #2235: __hash__ is once again inherited by default. To allow
5068 collections.Hashable to remain meaningful in the presence of the
5069 default hash implementation (object.__hash__), it is now possible
5070 to explicit block inheritance of hash by setting __hash__=None at
5071 the Python level, or tp_hash=PyObject_HashNotImplemented at the C
5072 level.
5073
Nick Coghlanb028f502008-07-13 14:52:36 +00005074- Issue #3221: Issue a RuntimeWarning instead of raising SystemError if
5075 the parent module cannot be found while performing an absolute import.
5076 This means that an incorrectly defined __package__ attribute will
5077 now only prevent relative imports in that module rather than causing
5078 all imports from that module to fail.
5079
Nick Coghlan14ff9942008-07-08 14:21:42 +00005080- Issue #2517: Allow unicode messages in Exceptions again by correctly
5081 bypassing the instance dictionary when looking up __unicode__ on
5082 new-style classes.
5083
Amaury Forgeot d'Arcbdd941f2008-07-01 20:38:04 +00005084- Issue #3242: Fix a crash inside the print statement, if sys.stdout is
5085 set to a custom object whose write() method happens to install
5086 another file in sys.stdout.
5087
Amaury Forgeot d'Arc1f40c8a2008-06-30 22:42:40 +00005088- Issue #3088: Corrected a race condition in classes derived from
5089 threading.local: the first member set by a thread could be saved in
5090 another thread's dictionary.
5091
Mark Dickinson1ec2fcd2008-06-20 14:53:43 +00005092- Issue #3004: Minor change to slice.indices(): the start and stop
5093 arguments are now treated identically, making the behaviour easier
5094 to describe and understand. For example, slice(None, -10,
5095 1).indices(9) now returns (0, 0, 1) instead of (0, -1, 1), and
5096 slice(None, 10, -1).indices(10) returns (9, 9, -1) instead of (9,
5097 10, -1).
5098
Georg Brandl278fc502008-07-19 12:46:12 +00005099- Issue #3219: Calling a function with repeated keyword arguments,
5100 f(a=2, a=23), would not cause a syntax error. This was a regression
5101 from 2.4 caused by the switch to the new compiler.

5112 error when they failed.

Georg Brandl5cc774e2008-06-11 20:28:06 +00005551 PPC64 and x86_64 support in one binary).
Ronald Oussoren5640ce22008-06-05 12:58:24 +00005552
5553 This is controlled by the configure argument ``--with-universal-archs``:
5554
5555 - ``--with-universal-archs=all``: install 4-way universal
5556
5557 - ``--with-universal-archs=32-bit``: install 2-way universal, 32-bit (the default)
5558
5559 - ``--with-universal-archs=64-bit``: install 2-way universal, 64-bit
5560
5561 This option should be used in combination with ``--enable-universalsdk=``.

Georg Brandl3ee81df2008-05-17 18:14:43 +00005613- Issue #1631171: Re-implement the 'warnings' module in C (the
5614 original Python code has been kept as backup). This will allow for
5615 using the 'warning's machinery in such places as the parser where
5616 use of pure Python code is not possible. Both the ``showarning()``
5617 and ``formatwarning()`` gain an optional 'line' argument which is
5618 not called by default for backwards-compatibility reasons. Setting
5619 ``warnings.showwarning()`` to an implementation that lacks support
5620 for the ``line`` argument will raise a DeprecationWarning.

Georg Brandl3ee81df2008-05-17 18:14:43 +00005675- Issue #2385: distutils.core.run_script() makes __file__ available,
5676 so the controlled environment will more closely mirror the typical
5677 script environment. This supports setup.py scripts that refer to
5678 data files.

Georg Brandl3ee81df2008-05-17 18:14:43 +00005683- Issue #2550: The approach used by client/server code for obtaining
5684 ports to listen on in network-oriented tests has been refined in an
5685 effort to facilitate running multiple instances of the entire
5686 regression test suite in parallel without issue.
5687 test_support.bind_port() has been fixed such that it will always
5688 return a unique port -- which wasn't always the case with the
5689 previous implementation, especially if socket options had been set
5690 that affected address reuse (i.e. SO_REUSEADDR, SO_REUSEPORT). The
5691 new implementation of bind_port() will actually raise an exception
5692 if it is passed an AF_INET/SOCK_STREAM socket with either the
5693 SO_REUSEADDR or SO_REUSEPORT socket option set. Furthermore, if
5694 available, bind_port() will set the SO_EXCLUSIVEADDRUSE option on
5695 the socket it's been passed. This currently only applies to
5696 Windows. This option prevents any other sockets from binding to the
5697 host/port we've bound to, thus removing the possibility of the
5698 'non-deterministic' behaviour, as Microsoft puts it, that occurs
5699 when a second SOCK_STREAM socket binds and accepts to a host/port
5700 that's already been bound by another socket. The optional preferred
5701 port parameter to bind_port() has been removed. Under no
5702 circumstances should tests be hard coding ports!
5703
5704 test_support.find_unused_port() has also been introduced, which will
5705 pass a temporary socket object to bind_port() in order to obtain an
5706 unused port. The temporary socket object is then closed and
5707 deleted, and the port is returned. This method should only be used
5708 for obtaining an unused port in order to pass to an external program
5709 (i.e. the -accept [port] argument to openssl's s_server mode) or as
5710 a parameter to a server-oriented class that doesn't give you direct
5711 access to the underlying socket used.
5712
5713 Finally, test_support.HOST has been introduced, which should be used
5714 for the host argument of any relevant socket calls (i.e. bind and
5715 connect).
Trent Nelsone41b0062008-04-08 23:47:30 +00005716
5717 The following tests were updated to following the new conventions:
Georg Brandl3ee81df2008-05-17 18:14:43 +00005718 test_socket, test_smtplib, test_asyncore, test_ssl, test_httplib,
Trent Nelsone41b0062008-04-08 23:47:30 +00005719 test_poplib, test_ftplib, test_telnetlib, test_socketserver,
5720 test_asynchat and test_socket_ssl.
5721
Georg Brandl3ee81df2008-05-17 18:14:43 +00005722 It is now possible for multiple instances of the regression test
5723 suite to run in parallel without issue.

Thomas Heller78b8f442008-03-05 14:53:39 +00005927- The bundled libffi copy is now in sync with the recently released
5928 libffi3.0.4 version, apart from some small changes to
Georg Brandl3ee81df2008-05-17 18:14:43 +00005929 Modules/_ctypes/libffi/configure.ac. On OS X, preconfigured libffi
5930 files are used. On all linux systems the --with-system-ffi
5931 configure option defaults to "yes".

Fred Drakea8ee94b2008-03-01 02:45:07 +00005992- Issue #2051: pyc and pyo files are no longer created with permission
Barry Warsaw52973612008-03-01 02:23:38 +00005993 644. The mode is now inherited from the py file.

Facundo Batistafc2d0102008-02-23 12:01:13 +00006001
Eric Smitha73fbe72008-02-23 03:09:44 +00006002- Added the future_builtins module, which contains hex() and oct().
6003 These are the PEP 3127 version of these functions, designed to be
6004 compatible with the hex() and oct() builtins from Python 3.0. They
6005 differ slightly in their output formats from the existing, unchanged
6006 Python 2.6 builtins. The expected usage of the future_builtins
6007 module is:
6008 from future_builtins import hex, oct
6009
Eric Smith7ef40bf2008-02-20 23:34:22 +00006010- Issue #1600: Modifed PyOS_ascii_formatd to use at most 2 digit
6011 exponents for exponents with absolute value < 100. Follows C99
6012 standard. This is a change on Windows, which would use 3 digits.
6013 Also, added 'n' to the formats that PyOS_ascii_formatd understands,
6014 so that any alterations it does to the resulting string will be
6015 available in stringlib/formatter.h (for float.__format__).
6016
Eric Smith5a3c1352008-02-19 13:21:56 +00006017- Implemented PEP 3101, Advanced String Formatting. This adds a new
6018 builtin format(); a format() method for str and unicode; a
6019 __format__() method to object, str, unicode, int, long, float, and
6020 datetime; the class string.Formatter; and the C API
6021 PyObject_Format().
6022
Georg Brandl3ee81df2008-05-17 18:14:43 +00006023- Fixed several potential crashes, all caused by specially crafted
6024 __del__ methods exploiting objects in temporarily inconsistent
6025 state.
Amaury Forgeot d'Arc632fad32008-02-16 20:55:24 +00006026
Vinay Sajipb7edfc42008-04-02 21:10:23 +00006027- Issue #2115: Important speedup in setting __slot__ attributes. Also
Georg Brandl3ee81df2008-05-17 18:14:43 +00006028 prevent a possible crash: an Abstract Base Class would try to access
6029 a slot on a registered virtual subclass.
Amaury Forgeot d'Arc60d6c7f2008-02-15 21:22:45 +00006030

Georg Brandl3ee81df2008-05-17 18:14:43 +00006034- Clear all free lists during a gc.collect() of the highest generation
6035 in order to allow pymalloc to free more arenas. Python may give back
6036 memory to the OS earlier.
Christian Heimes3b718a72008-02-14 12:47:33 +00006037
Georg Brandl3ee81df2008-05-17 18:14:43 +00006038- Issue #2045: Fix an infinite recursion triggered when printing a
6039 subclass of collections.defaultdict, if its default_factory is set
6040 to a bound method.
Amaury Forgeot d'Arcb01aa432008-02-08 00:56:02 +00006041
Christian Heimesf75dbef2008-02-08 00:11:31 +00006042- Fixed a minor memory leak in dictobject.c. The content of the free
6043 list was not freed on interpreter shutdown.
6044
Georg Brandl21e99f42010-03-07 15:23:59 +00006045- Limit free list of method and built-in function objects to 256
Georg Brandl3ee81df2008-05-17 18:14:43 +00006046 entries each.
Christian Heimes6075a822008-02-06 12:44:34 +00006047
Georg Brandl3ee81df2008-05-17 18:14:43 +00006048- Patch #1953: Added ``sys._compact_freelists()`` and the C API
6049 functions ``PyInt_CompactFreeList`` and ``PyFloat_CompactFreeList``
Christian Heimes422051a2008-02-04 18:00:12 +00006050 to compact the internal free lists of pre-allocted ints and floats.
6051
Georg Brandl3ee81df2008-05-17 18:14:43 +00006052- Issue #1983: Fixed return type of fork(), fork1() and forkpty()
6053 calls. Python expected the return type int but the fork familie
6054 returns pi_t.
Christian Heimes951cc0f2008-01-31 23:08:23 +00006055
Georg Brandl3ee81df2008-05-17 18:14:43 +00006056- Issue #1678380: Fix a bug that identifies 0j and -0j when they

Georg Brandl3ee81df2008-05-17 18:14:43 +00006068- Patch #1473257: generator objects gain a gi_code attribute. This is
6069 the same object as the func_code attribute of the function that
6070 produced the generator.
Georg Brandl0cdf9a32008-01-26 14:14:20 +00006071
Georg Brandl3ee81df2008-05-17 18:14:43 +00006072- Issue #1920: "while 0" statements were completely removed by the
6073 compiler, even in the presence of an "else" clause, which is
6074 supposed to be run when the condition is false. Now the compiler
6075 correctly emits bytecode for the "else" suite.
Amaury Forgeot d'Arc31eaafe2008-01-24 22:59:25 +00006076
Guido van Rossumeead05f2008-01-24 18:21:02 +00006077- A few crashers fixed: weakref_in_del.py (issue #1377858);
6078 loosing_dict_ref.py (issue #1303614, test67.py);
6079 borrowed_ref_[34].py (not in tracker).
6080
Vinay Sajipd7cf32e2008-01-24 12:43:33 +00006081- Issue #1069410: The "can't load dll" message box on Windows is
Christian Heimesb2302ba2008-01-23 17:15:06 +00006082 suppressed while an extension is loaded by calling SetErrorMode in
6083 dynload_win.c. The error is still reported properly.
6084
Georg Brandl3ee81df2008-05-17 18:14:43 +00006085- Issue #1915: Python compiles with --enable-unicode=no again. However
Christian Heimes082c9b02008-01-23 14:20:50 +00006086 several extension methods and modules do not work without unicode
6087 support.
6088
Georg Brandl26543b12008-01-21 18:36:51 +00006089- Issue #1882: when compiling code from a string, encoding cookies in the
6090 second line of code were not always recognized correctly.
6091
Georg Brandl14404b62008-01-19 19:27:05 +00006092- Issue #1679: "0x" was taken as a valid integer literal.
6093
Georg Brandl6caad7d2008-01-26 14:19:22 +00006094- Issue #1865: ``bytes`` as an alias for ``str`` and b"" as an alias "" were
Christian Heimes288e89a2008-01-18 18:24:07 +00006095 added.
6096
Christian Heimesc94e2b52008-01-14 04:13:37 +00006097- sys.float_info / PyFloat_GetInfo: The floating point information
6098 object was converted from a dict to a specialized structseq object.
6099
Georg Brandl3ee81df2008-05-17 18:14:43 +00006100- Patch #1816: Added sys.flags structseq. It exposes the status of
6101 most command line arguments and PYTHON* environment variables.
Christian Heimesf31b69f2008-01-14 03:42:48 +00006102
Georg Brandl3ee81df2008-05-17 18:14:43 +00006103- Objects/structseq.c: Implemented new structseq representation. The

6105 readable.
Christian Heimes9c201962008-01-14 03:33:52 +00006106
Georg Brandl3ee81df2008-05-17 18:14:43 +00006107- Patch #1700288: added a type attribute cache that caches method

Georg Brandl3ee81df2008-05-17 18:14:43 +00006129 and INF. float("nan"), float("inf") and float("-inf") now work on
6130 every platform with IEEE 754 semantics.
Christian Heimes0a8143f2007-12-18 23:22:54 +00006131
Georg Brandl3ee81df2008-05-17 18:14:43 +00006132- Compiler now generates simpler and faster code for dictionary
6133 literals. The oparg for BUILD_MAP now indicates an estimated
6134 dictionary size. There is a new opcode, STORE_MAP, for adding
6135 entries to the dictionary.

6171 executed code is closing a paused generator.
Amaury Forgeot d'Arc0d75f092007-11-13 21:54:28 +00006172
Raymond Hettinger1760c8a2007-11-08 02:52:43 +00006173- sets and frozensets now have an isdisjoint() method.

Neal Norwitz44f326e2007-10-05 05:29:17 +00006177- Fix warnings found by the new version of the Coverity checker.
6178
Georg Brandl21e99f42010-03-07 15:23:59 +00006179- The enumerate() built-in function is no longer bounded to sequences
Georg Brandl3ee81df2008-05-17 18:14:43 +00006180 smaller than LONG_MAX. Formerly, it raised an OverflowError. Now,
6181 automatically shifts from ints to longs.
Raymond Hettinger8f669372007-10-03 21:18:11 +00006182
Georg Brandl3ee81df2008-05-17 18:14:43 +00006183- Issue #1686386: Tuple's tp_repr did not take into account the
6184 possibility of having a self-referential tuple, which is possible
6185 from C code. Nor did object's tp_str consider that a type's tp_str
6186 could do something that could lead to an inifinite recursion.
6187 Py_ReprEnter() and Py_EnterRecursiveCall(), respectively, fixed the
6188 issues.
Brett Cannon0b14f242007-09-30 19:45:10 +00006189
Georg Brandl3ee81df2008-05-17 18:14:43 +00006190- Issue #1164: It was possible to trigger deadlock when using the
6191 'print' statement to write to a file since the GIL was not released
6192 as needed. Now PyObject_Print() does the right thing along with
6193 various tp_print implementations of the built-in types and those in
6194 the collections module.
Brett Cannon01531592007-09-17 03:28:34 +00006195
Georg Brandl3ee81df2008-05-17 18:14:43 +00006196- Issue #1147: Exceptions were directly allowing string exceptions in
6197 their throw() method even though string exceptions no longer
6198 allowed.

Brett Cannona0c05512007-09-10 21:38:27 +00006202
Brett Cannon1e534b52007-09-07 04:18:30 +00006203- Issue #1202533: Fix infinite recursion calls triggered by calls to
Georg Brandl3ee81df2008-05-17 18:14:43 +00006204 PyObject_Call() never calling back out to Python code to trigger
6205 recursion depth updates/checks. Required the creation of a static
6206 RuntimeError instance in case normalizing an exception put the
6207 recursion check value past its limit. Fixes crashers
6208 infinite_rec_(1|2|4|5).py.
Brett Cannon1e534b52007-09-07 04:18:30 +00006209

Neal Norwitz0ac60192007-05-27 04:08:54 +00006223- Add new attribute names for function objects. All the func_* become
Georg Brandl3ee81df2008-05-17 18:14:43 +00006224 __*__ attributes. (Some already existed, e.g., __doc__ and
6225 __name__.)
Neal Norwitz0ac60192007-05-27 04:08:54 +00006226
Neal Norwitz8b2bfbc2007-05-23 06:35:32 +00006227- Add -3 option to the interpreter to warn about features that are
6228 deprecated and will be changed/removed in Python 3.0.
6229
Georg Brandl2134e752007-05-21 20:34:16 +00006230- Patch #1686487: you can now pass any mapping after '**' in function
6231 calls.
6232
Collin Winter62903052007-05-18 23:11:24 +00006233- except clauses may now be spelled either "except E, target:" or
Georg Brandl3ee81df2008-05-17 18:14:43 +00006234 "except E as target:". This is to provide forwards compatibility
6235 with Python 3.0.
Collin Winter62903052007-05-18 23:11:24 +00006236
Brett Cannon229cee22007-05-05 01:34:02 +00006237- Deprecate BaseException.message as per PEP 352.

Vinay Sajip8549ce32007-05-06 17:53:37 +00006242- When __slots__ are set to a unicode string, make it work the same as
Neal Norwitzcbd9ee62007-04-14 05:25:50 +00006243 setting a plain string, ie don't expand to single letter identifiers.
6244
Raymond Hettinger13936692007-04-11 18:40:58 +00006245- Request #1191699: Slices can now be pickled.
6246
Raymond Hettinger4db5fe92007-04-12 04:10:00 +00006247- Request #1193128: str.translate() now allows a None argument for
6248 translations that only remove characters without re-mapping the
6249 remaining characters.
6250
Georg Brandl5cb76c12007-03-21 09:00:39 +00006251- Patch #1682205: a TypeError while unpacking an iterable is no longer

6255
Guido van Rossum143b5642007-03-23 04:58:42 +00006256- Bug #1683368: The object.__init__() and object.__new__() methods are
6257 now stricter in rejecting excess arguments. The only time when
6258 either allows excess arguments is when it is not overridden and the
6259 other one is. For backwards compatibility, when both are
6260 overridden, it is a deprecation warning (for now; maybe a Py3k
Guido van Rossum234b1ff2007-03-23 19:39:01 +00006261 warning later). Also, type.__init__() insists on the same signature
6262 as supported by type.__new__().
Guido van Rossum143b5642007-03-23 04:58:42 +00006263
Georg Brandl3ee81df2008-05-17 18:14:43 +00006264- Patch #1675423: PyComplex_AsCComplex() now tries to convert an
6265 object to complex using its __complex__() method before falling back
6266 to the __float__() method. Therefore, the functions in the cmath
6267 module now can operate on objects that define a __complex__()
6268 method.
Georg Brandl2b869942007-03-17 16:08:45 +00006269
Georg Brandl3ee81df2008-05-17 18:14:43 +00006270- Patch #1623563: allow __class__ assignment for classes with

6279 its type.

6285
Georg Brandl7b9c5552007-03-12 14:30:05 +00006286- Bug #1678647: write a newline after printing an exception in any
6287 case, even when converting the value to a string failed.
6288
Georg Brandl871f1bc2007-03-12 13:17:36 +00006289- The dir() function has been extended to call the __dir__() method on
Georg Brandl3ee81df2008-05-17 18:14:43 +00006290 its argument, if it exists. If not, it will work like before. This
6291 allows customizing the output of dir() in the presence of a
6292 __getattr__().

Georg Brandl3ee81df2008-05-17 18:14:43 +00006300- Patch #1491866: change the complex() constructor to allow
6301 parthensized forms. This means complex(repr(x)) now works instead of
6302 raising a ValueError.
Collin Wintere38051d2007-03-09 20:33:07 +00006303
Georg Brandlaa2321b2007-03-07 00:40:28 +00006304- Patch #703779: unset __file__ in __main__ after running a file. This
Georg Brandl3ee81df2008-05-17 18:14:43 +00006305 makes the filenames the warning module prints much more sensible
6306 when a PYTHONSTARTUP file is used.
Georg Brandlaa2321b2007-03-07 00:40:28 +00006307

Georg Brandl0fca97a2007-03-05 22:28:08 +00006319- Patch #1674228: when assigning a slice (old-style), check for the
6320 sq_ass_slice instead of the sq_slice slot.
6321
Georg Brandl3ee81df2008-05-17 18:14:43 +00006322- When printing an unraisable error, don't print exceptions. before
6323 the name. This duplicates the behavior whening normally printing
6324 exceptions.

6952 -- the failure just occurred later, with a more cumbersome
6953 exception.

7166 partial fix for Bug #1574584.
7167
Georg Brandl3ee81df2008-05-17 18:14:43 +00007168- Fix turtle so that time.sleep is imported for the entire library.

Georg Brandl3ee81df2008-05-17 18:14:43 +00007234- Issue #829951: In the smtplib module, SMTP.starttls() now complies
7235 with RFC 3207 and forgets any knowledge obtained from the server not
7236 obtained from the TLS negotiation itself. Patch contributed by Bill
7237 Fenner.
Gregory P. Smith2b3ba582008-01-17 08:03:17 +00007238
Georg Brandl3ee81df2008-05-17 18:14:43 +00007239- Issue #1339: The smtplib.SMTP class has been refactored a bit such
Gregory P. Smithbde4ae42008-01-17 08:35:49 +00007240 that the SMTP.starttls() caller no longer needs to call ehlo()
7241 beforehand. SMTP.starttls() now raises an exception of the server
Georg Brandl3ee81df2008-05-17 18:14:43 +00007242 does not claim to support starttls. Adds the
7243 SMTP.ehlo_or_helo_if_needed() method. Patch contributed by Bill
7244 Fenner.

7282
Georg Brandl3ee81df2008-05-17 18:14:43 +00007283- Patch #1663329: added ``os.closerange()`` function to quickly close

Georg Brandl3ee81df2008-05-17 18:14:43 +00007286- Patch #976880: ``mmap`` objects now have an ``rfind`` method that
Andrew M. Kuchling5c60bfc2008-01-19 18:18:41 +00007287 works as expected. ``mmap.find`` also takes an optional ``end``
7288 parameter.

Georg Brandl3ee81df2008-05-17 18:14:43 +00007298- itertools.chain() now has an alternate constructor,

7313 contents before adding elements from the iterable. This fix brings
7314 the behavior into line with that for list.__init__().
Raymond Hettingeradf9ffd2007-12-13 00:08:37 +00007315
Georg Brandl3ee81df2008-05-17 18:14:43 +00007316- Added wide char functions to msvcrt module: getwch, getwche, putwch

7324 complex, tuple, list, dict, set, and frozenset. Formerly, it would
7325 silently miscode subclasses of those types. Now, it raises a
7326 ValueError instead.
Raymond Hettinger12e94202007-11-07 01:13:09 +00007327

Georg Brandl3ee81df2008-05-17 18:14:43 +00007342 time so that opening a database previously created with the DB_DUP
7343 or DB_DUPSORT flag set will keep the proper behavior on subsequent
7344 opens. Specifically: dictionary assignment to a DB object will
7345 replace all values for a given key when the database allows
7346 duplicate values. DB users should use DB.put(k, v) when they want
7347 to store duplicates; not DB[k] = v.
Gregory P. Smithec10a4a2007-11-05 02:32:26 +00007348

7354 characters with ASCII value less than 32. Also, it correctly quotes
7355 dots only if they occur on a single line, as opposed to the previous
7356 behavior of quoting dots if they are the second character of any
7357 line.
Georg Brandl4aef7272007-03-13 22:49:43 +00007358

7681
Georg Brandl3ee81df2008-05-17 18:14:43 +00007682- Unified naming convention for free lists and their limits. All free
7683 lists in Object/ are named ``free_list``, the counter ``numfree``
7684 and the upper limit is a macro ``PyName_MAXFREELIST`` inside an
7685 #ifndef block.
Christian Heimes5b970ad2008-02-06 13:33:44 +00007686
Georg Brandl3ee81df2008-05-17 18:14:43 +00007687- ``PySet_Add()`` can now modify a newly created frozenset. Similarly
7688 to ``PyTuple_SetItem``, it can be used to populate a brand new
7689 frozenset; but it does not steal a reference to the added item.

7701
Georg Brandl3ee81df2008-05-17 18:14:43 +00007702- Issue #1521: On 64bit platforms, using PyArgs_ParseTuple with the t#
7703 of w# format code incorrectly truncated the length to an int, even
7704 when PY_SSIZE_T_CLEAN is set. The str.decode method used to return
7705 incorrect results with huge strings.
Georg Brandl6caad7d2008-01-26 14:19:22 +00007706
Georg Brandl3ee81df2008-05-17 18:14:43 +00007707- Issue #1629: Renamed Py_Size, Py_Type and Py_Refcnt to Py_SIZE,

7725- Fix some leftovers from the conversion from int to Py_ssize_t
7726 (relevant to strings and sequences of more than 2**31 items).
7727
7728- Make _PyGILState_NoteThreadState() static, it was not used anywhere
7729 outside of pystate.c and should not be necessary.
7730
Georg Brandl3ee81df2008-05-17 18:14:43 +00007731- ``PyImport_Import`` and ``PyImport_ImportModule`` now always do
7732 absolute imports. In earlier versions they might have used relative
7733 imports under some conditions.
Christian Heimes000a0742008-01-03 22:16:32 +00007734
Georg Brandl3ee81df2008-05-17 18:14:43 +00007735- Added case insensitive comparison methods ``PyOS_stricmp(char*,
7736 char*)`` and ``PyOS_strnicmp(char*, char*, Py_ssize_t)``.
Christian Heimes000a0742008-01-03 22:16:32 +00007737
Georg Brandl3ee81df2008-05-17 18:14:43 +00007738- Bug #1542693: remove semi-colon at end of PyImport_ImportModuleEx

7746 requires Windows 2000 or greater. The _WINVER and NTDDI_VERSION
7747 macros are set to Win2k for x86/32bit builds and WinXP for AMD64
7748 builds.
Christian Heimes95d64472008-02-09 19:55:22 +00007749

Georg Brandl3ee81df2008-05-17 18:14:43 +00007763- Removed the macfs module. It had been deprecated since Python 2.5.
7764 This lead to the deprecation of macostools.touched() as it relied
7765 solely on macfs and was a no-op under OS X.
