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
43 incorrect results with recent versions of Clang, as a result of the
Mark Dickinsona96b0d12011-09-24 09:01:16 +010044 compiler optimizing the check away. Also fix similar overflow checks
45 in list_repeat (listobject.c) and islice_next (itertoolsmodule.c). These

92 raised when the wrapped raw file is non-blocking and the write would block.
93 Previous code assumed that the raw write() would raise BlockingIOError, but
94 RawIOBase.write() is defined to returned None when the call would block.

282
Ned Deily87e82bb2011-06-28 19:52:59 -0700283- Issue #9516: On Mac OS X, change Distutils to no longer globally attempt to
284 check or set the MACOSX_DEPLOYMENT_TARGET environment variable for the
285 interpreter process. This could cause failures in non-Distutils subprocesses
286 and was unreliable since tests or user programs could modify the interpreter
287 environment after Distutils set it. Instead, have Distutils set the the
288 deployment target only in the environment of each build subprocess. It is
289 still possible to globally override the default by setting
290 MACOSX_DEPLOYMENT_TARGET before launching the interpreter; its value must be
291 greater or equal to the default value, the value with which the interpreter
292 was built.

1198 received. Now sendall() properly calls signal handlers if necessary,
1199 and retries sending if these returned successfully, including on sockets

1217 by Andrew Bennetts.

1226
Raymond Hettinger20397532010-09-12 02:11:45 +00001227- Issue #9825: removed __del__ from the definition of collections.OrderedDict.
1228 This prevents user-created self-referencing ordered dictionaries from
1229 becoming permanently uncollectable GC garbage. The downside is that
1230 removing __del__ means that the internal doubly-linked list has to wait for
1231 GC collection rather than freeing memory immediately when the refcnt drops
1232 to zero.
1233

1241 original error is re-raised.

1261 falling into recursion.
1262
R. David Murray7c4bf552010-08-25 01:45:57 +00001263- Issue #1194222: email.utils.parsedate now returns RFC2822 compliant four
1264 character years even if the message contains RFC822 two character years.
1265
Daniel Stutzbach91287322010-08-24 21:09:30 +00001266- Issue #8750: Fixed MutableSet's methods to correctly handle

1285
Raymond Hettingera54b2da2010-08-17 19:03:06 +00001286- Issue #9626: the view methods for collections.OrderedDict() were returning

1295 and a BadZipfile error is raised if it doesn't match (as used to be the
1296 case in Python 2.5 and earlier).
1297
Antoine Pitroucb4f47c2010-08-11 13:40:17 +00001298- Issue #9550: a BufferedReader could issue an additional read when the
1299 original read request had been satisfied, which could block indefinitely
1300 when the underlying raw IO channel was e.g. a socket. Report and original
1301 patch by Jason V. Miller.
1302
Fred Drake0a1fa0e2010-08-10 13:09:54 +00001303- Issue #9551: Don't raise TypeError when setting the value to None for

1694 E.g.: '\xf1\x80AB'.decode('utf-8', 'replace') now returns u'\ufffdAB' and
1695 replaces with U+FFFD only the start byte ('\xf1') and the continuation byte

1707 (2**53+1 == complex(2**53) == 2**53), breaking transivity of equality.

Mark Dickinsond2f3e3f2010-05-05 22:23:58 +00002052 (Optimization was unintentionally turned on in gcc --with-pydebug builds in
2053 2.7 beta1 as a result of the issue #1628484 fix, combined with autoconf's
2054 strange choice of default CFLAGS produced by AC_PROG_CC for gcc.)

2075-----------------
2076
Philip Jenveyaebbaeb2010-04-06 23:24:45 +00002077- Issue #7301: Add environment variable $PYTHONWARNINGS.
2078
Benjamin Peterson3a1dfa22010-04-06 21:50:00 +00002079- Issue #8329: Don't return the same lists from select.select when no fds are
2080 changed.
2081
Georg Brandlfee0f442010-05-22 21:26:21 +00002082- Issue #8259: ``1L << (2**31)`` no longer produces an 'outrageous shift error'
Mark Dickinson82791672010-04-06 16:47:55 +00002083 on 64-bit machines. The shift count for either left or right shift is
2084 permitted to be up to sys.maxsize.
2085
Benjamin Peterson4ceeeb02010-04-03 22:48:51 +00002086- Ensure that tokenization of identifiers is not affected by locale.
2087
Georg Brandlfee0f442010-05-22 21:26:21 +00002088- Issue #1222585: Added LDCXXSHARED for C++ support. Patch by Arfrever.
Tarek Ziadé00002952010-04-03 08:37:59 +00002089
Benjamin Peterson1c7c11e2010-04-03 01:28:57 +00002090- Raise a TypeError when trying to delete a T_STRING_INPLACE struct member.
2091
Georg Brandlfee0f442010-05-22 21:26:21 +00002092- Issue #7994: Issue a PendingDeprecationWarning if object.__format__ is called
2093 with a non-empty format string. This is an effort to future-proof user
2094 code. If a derived class does not currently implement __format__ but later
2095 adds its own __format__, it would most likely break user code that had
Antoine Pitrou01a196a2011-01-02 20:05:11 +00002096 supplied a format string. This will be changed to a DeprecationWarning in
Georg Brandlfee0f442010-05-22 21:26:21 +00002097 Python 3.3 and it will be an error in Python 3.4.
Eric Smithd44b2fc2010-04-02 12:30:56 +00002098
Antoine Pitroua57df2c2010-03-31 21:32:15 +00002099- Issue #8268: Old-style classes (not just instances) now support weak

Victor Stinner66644262010-03-10 22:30:19 +00002112- Issue #3137: Don't ignore errors at startup, especially a keyboard interrupt
Georg Brandlba83f822010-03-14 09:50:54 +00002113 (SIGINT). If an error occurs while importing the site module, the error is

Georg Brandlfee0f442010-05-22 21:26:21 +00002130- Issue #8257: The Decimal construct now accepts a float instance directly,
2131 converting that float to a Decimal of equal value:
Mark Dickinson8a950712010-04-03 15:47:46 +00002132
2133 >>> Decimal(1.1)
2134 Decimal('1.100000000000000088817841970012523233890533447265625')
2135
Raymond Hettinger34c35b22010-04-03 10:22:00 +00002136- collections.Counter() now supports a subtract() method.
2137
Georg Brandlfee0f442010-05-22 21:26:21 +00002138- The functools module now has a total_ordering() class decorator to simplify
2139 the specification of rich comparisons.

Georg Brandlfee0f442010-05-22 21:26:21 +00002141- The functools module also adds cmp_to_key() as a tool to transition old-style
2142 comparison functions to new-style key-functions.
Raymond Hettingera551f312010-04-04 18:34:45 +00002143
Georg Brandlfee0f442010-05-22 21:26:21 +00002144- Issue #8294: The Fraction constructor now accepts Decimal and float instances
2145 directly.

Georg Brandlfee0f442010-05-22 21:26:21 +00002147- Issue #7279: Comparisons involving a Decimal signaling NaN now signal
2148 InvalidOperation instead of returning False. (Comparisons involving a quiet
2149 NaN are unchanged.) Also, Decimal quiet NaNs are now hashable; Decimal
2150 signaling NaNs remain unhashable.
Mark Dickinsone096e822010-04-02 10:17:07 +00002151
Georg Brandlfee0f442010-05-22 21:26:21 +00002152- Issue #2531: Comparison operations between floats and Decimal instances now
2153 return a result based on the numeric values of the operands; previously they
2154 returned an arbitrary result based on the relative ordering of id(float) and
2155 id(Decimal).
Mark Dickinson99d80962010-04-02 08:53:22 +00002156
Barry Warsawf7f2d6f2010-03-31 21:07:16 +00002157- Issue #8233: When run as a script, py_compile.py optionally takes a single
Georg Brandlfee0f442010-05-22 21:26:21 +00002158 argument `-` which tells it to read files to compile from stdin. Each line is
2159 read on demand and the named file is compiled immediately. (Original patch by
2160 Piotr Ożarowski).

Florent Xicluna58b65662010-03-30 16:29:03 +00002165- Backwards incompatible change: Unicode codepoints line tabulation (0x0B) and
2166 form feed (0x0C) are now considered linebreaks, as specified in Unicode
Georg Brandlfee0f442010-05-22 21:26:21 +00002167 Standard Annex #14. See issue #7643. http://www.unicode.org/reports/tr14/
Florent Xicluna22b24382010-03-30 08:24:06 +00002168
Georg Brandlfee0f442010-05-22 21:26:21 +00002169- Comparisons using one of <, <=, >, >= between a complex instance and a
2170 Fractions instance now raise TypeError instead of returning True/False. This
2171 makes Fraction <=> complex comparisons consistent with int <=> complex, float
2172 <=> complex, and complex <=> complex comparisons.

Georg Brandlba83f822010-03-14 09:50:54 +00002240- Issue #7143: email: ``get_payload()`` used to strip any trailing newline from

Mark Dickinson4846a8e2010-04-03 14:05:10 +00002271- Issue #8300: When passing a non-integer argument to struct.pack with any
2272 integer format code, struct.pack first attempts to convert the non-integer

Georg Brandlba83f822010-03-14 09:50:54 +00002276- Issue #1530559: When passing a non-integer argument to struct.pack with *any*
2277 integer format code (one of 'bBhHiIlLqQ'), struct.pack attempts to use the
2278 argument's __int__ method to convert to an integer before packing. It also
Georg Brandlfee0f442010-05-22 21:26:21 +00002279 produces a DeprecationWarning in this case. (In Python 2.6, the behaviour was
2280 inconsistent: __int__ was used for some integer codes but not for others, and
2281 the set of integer codes for which it was used differed between native packing
2282 and standard packing.)

Georg Brandlba83f822010-03-14 09:50:54 +00002534- Issue #7561: Operations on empty bytearrays (such as ``int(bytearray())``)
2535 could crash in many places because of the ``PyByteArray_AS_STRING()`` macro
2536 returning NULL. The macro now returns a statically allocated empty string
2537 instead.

Antoine Pitroud840e512010-02-04 20:20:18 +00002582- Issue #4772: Raise a ValueError when an unknown Bluetooth protocol is
Georg Brandlba83f822010-03-14 09:50:54 +00002583 specified, rather than fall through to AF_PACKET (in the ``socket`` module).

Antoine Pitrouf3fa0742010-01-31 22:26:04 +00002589- Issue #6939: Fix file I/O objects in the `io` module to keep the original
Georg Brandlba83f822010-03-14 09:50:54 +00002590 file position when calling `truncate()`. It would previously change the file
2591 position to the given argument, which goes against the tradition of
Antoine Pitrouf3fa0742010-01-31 22:26:04 +00002592 ftruncate() and other truncation APIs. Patch by Pascal Chambon.
2593
Georg Brandlba83f822010-03-14 09:50:54 +00002594- Issue #7610: Reworked implementation of the internal ``zipfile.ZipExtFile``
2595 class used to represent files stored inside an archive. The new
2596 implementation is significantly faster and can be wrapped in a
2597 ``io.BufferedReader`` object for more speedups. It also solves an issue
2598 where interleaved calls to ``read()`` and ``readline()`` give wrong results.
2599 Patch by Nir Aides.

Georg Brandlba83f822010-03-14 09:50:54 +00002609- Issue #7748: Since unicode values are supported for some metadata options in
2610 Distutils, the DistributionMetadata get_* methods will now return an utf-8
2611 encoded string for them. This ensures that the upload and register commands
2612 send the correct values to PyPI without any error.

Georg Brandlba83f822010-03-14 09:50:54 +00002883- Issue #7117: ``repr(x)`` for a float x returns a result based on the shortest
2884 decimal string that's guaranteed to round back to x under correct rounding
2885 (with round-half-to-even rounding mode). Previously it gave a string based on
2886 rounding x to 17 decimal digits. repr(x) for a complex number behaves
2887 similarly. On platforms where the correctly-rounded strtod and dtoa code is
2888 not supported (see below), repr is unchanged.
Mark Dickinsonb678de82009-11-19 18:41:49 +00002889
Georg Brandlba83f822010-03-14 09:50:54 +00002890- Issue #7117: On almost all platforms: float-to-string and string-to-float
2891 conversions within Python are now correctly rounded. Places these conversions
2892 occur include: str for floats and complex numbers; the float and complex
2893 constructors; old-style and new-style numeric formatting; serialization and
2894 deserialization of floats and complex numbers using marshal, pickle and json;
2895 parsing of float and imaginary literals in Python code; Decimal-to-float
2896 conversion.
Mark Dickinsonb678de82009-11-19 18:41:49 +00002897
Georg Brandlba83f822010-03-14 09:50:54 +00002898 The conversions use a Python-adapted version of David Gay's well-known dtoa.c,
2899 providing correctly-rounded strtod and dtoa C functions. This code is
2900 supported on Windows, and on Unix-like platforms using gcc, icc or suncc as
2901 the C compiler. There may be a small number of platforms on which correct
2902 operation of this code cannot be guaranteed, so the code is not used: notably,
2903 this applies to platforms where the C double format is not IEEE 754 binary64,
2904 and to platforms on x86 hardware where the x87 FPU is set to 64-bit precision
2905 and Python's configure script is unable to determine how to change the FPU
2906 precision. On these platforms conversions use the platform strtod and dtoa,
2907 as before.

Georg Brandlba83f822010-03-14 09:50:54 +00002909- Issue #7117: Backport round implementation from Python 3.x. ``round()`` now
2910 uses the correctly-rounded string <-> float conversions described above (when
2911 available), and so produces correctly rounded results that will display nicely
2912 under the float repr. There are two related small changes: (1) round now
2913 accepts any class with an ``__index__()`` method for its second argument (but
2914 no longer accepts floats for the second argument), and (2) an excessively
2915 large second integer argument (e.g., ``round(1.234, 10**100)``) no longer
2916 raises an exception.

Georg Brandlba83f822010-03-14 09:50:54 +00003063- Issue #5920: For ``float.__format__()``, change the behavior with the empty
3064 presentation type (that is, not one of 'e', 'f', 'g', or 'n') to be like 'g'
3065 but with at least one decimal point and with a default precision
3066 of 12. Previously, the behavior the same but with a default precision of 6.
3067 This more closely matches ``str()``, and reduces surprises when adding

3069 complex.__format__ in the same way.

Georg Brandl29c6a282009-04-05 20:23:13 +00003178- Issue #1242657: the __len__() and __length_hint__() calls in several tools
Raymond Hettingerb5163702009-02-02 21:50:13 +00003179 were suppressing all exceptions. These include list(), filter(), map(),

Georg Brandlba83f822010-03-14 09:50:54 +00003209- Issue #1180193: When importing a module from a .pyc (or .pyo) file with an
3210 existing .py counterpart, override the co_filename attributes of all code
3211 objects if the original filename is obsolete (which can happen if the file has

3259 instead of throwing a MemoryError.
3260
Georg Brandlba83f822010-03-14 09:50:54 +00003261- Issue #3689: The list reversed iterator now supports __length_hint__ instead

3266
Georg Brandlba83f822010-03-14 09:50:54 +00003267- Issue #4233: Changed semantic of ``_fileio.FileIO``'s ``close()`` method on
3268 file objects with closefd=False. The file descriptor is still kept open but
3269 the file object behaves like a closed file. The ``FileIO`` object also got a
3270 new readonly attribute ``closefd``.

3289
Benjamin Peterson399b1fe2008-10-25 02:53:28 +00003290- Using ``nonlocal`` as a variable name will now raise a Py3k SyntaxWarning
Georg Brandl7fb00ad2008-10-25 07:00:52 +00003291 because it is a reserved word in 3.x.

Georg Brandlba83f822010-03-14 09:50:54 +00003293- On windows, ``os.chdir()`` given unicode was not working if
3294 GetCurrentDirectoryW returned a path longer than MAX_PATH. (But It's doubtful
3295 this code path is really executed because I cannot move to such directory on
3296 win2k)

Georg Brandlba83f822010-03-14 09:50:54 +00003298- Issue #4069: When ``set.remove(element)`` is used with a set element, the
3299 element is temporarily replaced with an equivalent frozenset. But the
3300 eventual KeyError would always report the empty ``frozenset()`` as the missing
3301 key. Now it correctly refers to the initial element.

Walter Dörwalded960ac2009-05-03 22:36:33 +00003321- Issue #5108: Handle %s like %S and %R in PyUnicode_FromFormatV(): Call
3322 PyUnicode_DecodeUTF8() once, remember the result and output it in a second
3323 step. This avoids problems with counting UTF-8 bytes that ignores the effect
3324 of using the replace error handler in PyUnicode_DecodeUTF8().
3325
Walter Dörwald726ba8e2009-05-06 14:32:35 +00003326- Issue #3739: The unicode-internal encoder now reports the number of characters

3328
Georg Brandlba83f822010-03-14 09:50:54 +00003329- Issue #2422: When compiled with the ``--with-valgrind`` option, the pymalloc
3330 allocator will be automatically disabled when running under Valgrind. This
3331 gives improved memory leak detection when running under Valgrind, while taking
3332 advantage of pymalloc at other times.

4540 in the Lib/test directory, which might be read-only for the user running the
4541 tests.

Georg Brandlba83f822010-03-14 09:50:54 +00004555 leak-chasing test runs give sensible results. The previous method of reaping
4556 threads could return successfully while some Thread objects were still
4557 referenced. This also introduces a new private function: ``thread._count()``.

Georg Brandlba83f822010-03-14 09:50:54 +00004559- Issue #7151: Fixed regrtest -j so that output to stderr from a test no longer

4567 and a new section in the summary report at the end.

Guilherme Polo7f146ab2009-06-21 17:22:50 +00004574- Issue #5450: Moved tests involving loading tk from Lib/test/test_tcl to
4575 Lib/lib-tk/test/test_tkinter/test_loadtk. With this, these tests demonstrate
Georg Brandlba83f822010-03-14 09:50:54 +00004576 the same behaviour as test_ttkguionly (and now also test_tk) which is to skip
4577 the tests if DISPLAY is defined but can't be used.

4583 import both normal and optimised versions of modules. test_heapq and
4584 test_warnings have been adjusted to use it, tests for other modules with both
4585 C and Python implementations in the stdlib can be adjusted to use it over
4586 time.

Georg Brandlba83f822010-03-14 09:50:54 +00004594- regrtest no longer treats ImportError as equivalent to SkipTest. Imports that
4595 should cause a test to be skipped are now done using import_module from test
4596 support, which does the conversion.

4698
Amaury Forgeot d'Arc05e34492008-09-10 22:04:45 +00004699- Issue #3743: In a few places, PY_FORMAT_SIZE_T was incorrectly used with
4700 PyString_FromFormat or PyErr_Format to display size_t values. The macro
4701 PY_FORMAT_SIZE_T is designed to select the correct format for the OS
4702 ``printf`` function, whereas PyString_FromFormat has an independent
4703 implementation and uses "%zd" on all platforms for size_t values.
4704 This makes a difference on win64, where ``printf`` needs "%Id" to display
4705 64bit values.

Benjamin Peterson97179b02008-09-09 20:55:01 +00004707- Issue #3634: _weakref.ref(Exception).__init__() gave invalid return value on

4711 object; previously an int would be returned for small values. the __long__
4712 method is allowed to return either an int or a long, but the behaviour of

Vinay Sajip35e3b032008-09-01 14:33:59 +00004724- Issue #2534: speed up isinstance() and issubclass() by 50-70%, so as to
Antoine Pitrou0668c622008-08-26 22:42:08 +00004725 match Python 2.5 speed despite the __instancecheck__ / __subclasscheck__
4726 mechanism. In the process, fix a bug where isinstance() and issubclass(),

4728 __instancecheck__ / __subclasscheck__ on the tuple rather than on each
4729 type object.

4823
Jesse Noller438195f2009-01-18 21:04:36 +00004824- Issue #4301: Patch the logging module to add processName support, remove
4825 _check_logger_class from multiprocessing.
4826
Amaury Forgeot d'Arc293924b2008-09-02 23:19:56 +00004827- Issue #2975: When compiling several extension modules with Visual Studio 2008
4828 from the same python interpreter, some environment variables would grow
4829 without limit.
4830
Benjamin Peterson37346b22008-08-23 20:27:43 +00004831- Issue #3643: Added a few more checks to _testcapi to prevent segfaults by
4832 exploitation of poor argument checking.
4833
Gerhard Häringef2276b2008-09-12 13:54:06 +00004834- sqlite3: Changed docstring of iterdump() to mark method as "Non-standard".
4835
Gerhard Häring6e1afcf2008-09-12 18:58:57 +00004836- Issue #3103: Reduced globals symbols used by sqlite3 module and made sure all
4837 remaining ones have "pysqlite_" prefix.
4838
Gerhard Häringe6872eb2008-09-12 22:33:22 +00004839- Issue #3846: Release the GIL during sqlite3_prepare calls. This improves

4847 wrapper for warnings.catch_warnings() that makes it easier to check
4848 that expected warning messages are being reported.
4849
Amaury Forgeot d'Arcfeb8cad2008-09-06 20:53:51 +00004850- Issue #3796: Some tests functions were not enabled in test_float.

Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00004868What's New in Python 2.6 beta 3?
4869================================
4870
Barry Warsaw07a4a382008-08-21 01:15:08 +00004871*Release date: 20-Aug-2008*
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00004872
4873Core and Builtins
4874-----------------
4875
Guido van Rossumf8402962008-08-20 15:01:50 +00004876- Issue #1878: Remove Py_TPFLAGS_HAVE_VERSION_TAG from
4877 Py_TPFLAGS_DEFAULT when not building the core. This means 3rd party
4878 extensions do not automatically benefit from the class attribute
4879 cache; they will have to explicitly add Py_TPFLAGS_HAVE_VERSION_TAG
4880 to their tp_flags field if they care. This is a backwards
4881 compatibility feature; in 3.0, all types will use the cache by
4882 default.
4883
Benjamin Petersonf647dc12008-08-20 01:27:30 +00004884- Keyword arguments can now follow starred arguments. (``f(a, *args,
4885 keyword=23)`` is now valid syntax.)
4886
Thomas Heller0ad5ae02008-08-19 19:25:04 +00004887- ctypes function pointers that are COM methods have a boolean True
4888 value again.
4889
Martin v. Löwisf91d46a2008-08-12 14:49:50 +00004890- Issue #3139: Make buffer-interface thread-safe wrt. PyArg_ParseTuple,
4891 by denying s# to parse objects that have a releasebuffer procedure,
4892 and introducing s*.
4893
Georg Brandl1e13ea92008-08-11 09:07:59 +00004894- Issue #3537: Fix an assertion failure when an empty but presized dict
4895 object was stored in the freelist.
4896
Mark Dickinsonb6467572008-08-04 21:30:09 +00004897- Issue #1481296: Make long(float('nan')) and int(float('nan')) raise
4898 ValueError consistently across platforms.
4899
Amaury Forgeot d'Arc39fd6722008-07-31 21:28:03 +00004900- Issue #3479: On platforms where sizeof(int) is smaller than sizeof(long)
4901 (64bit Unix, for example), unichr() would truncate its argument and return
4902 u'\x00' for unichr(2**32). Now it properly raises an OverflowError.
4903
Neal Norwitze7d8be82008-07-31 17:17:14 +00004904- Apply security patches from Apple.
4905
Amaury Forgeot d'Arc246daed2008-07-31 00:42:16 +00004906- Issue #2542: Now that issubclass() may call arbitrary code, ensure that
4907 PyErr_ExceptionMatches returns 0 when an exception occurs there.
4908
Antoine Pitrou92f82162008-07-25 22:22:08 +00004909- Issue #1819: function calls with several named parameters are now on
4910 average 35% faster (as measured by pybench).
4911
Amaury Forgeot d'Arce4921fe2008-07-21 22:00:38 +00004912- Issue #2378: An unexpected UnboundLocalError or NameError could appear when
4913 the python debugger steps into a class statement: the free variables (local
4914 variables defined in an outer scope) would be deleted from the outer scope.
4915
Gregory P. Smith0470bab2008-07-22 04:46:32 +00004916- Issue #2620: Overflow checking when allocating or reallocating memory
4917 was not always being done properly in some python types and extension
4918 modules. PyMem_MALLOC, PyMem_REALLOC, PyMem_NEW and PyMem_RESIZE have
4919 all been updated to perform better checks and places in the code that
4920 would previously leak memory on the error path when such an allocation
4921 failed have been fixed.
4922
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00004923Library
4924-------
4925
Hirokazu Yamamoto838c79f2008-08-20 13:14:07 +00004926- Issue #3612: Added some missing basic types in ctypes.wintypes.
4927
Benjamin Petersone977ad42008-08-20 01:42:01 +00004928- The methods ``is_in_tuple()``, ``is_vararg()``, and ``is_keywordarg()`` of
4929 symtable.Symbol have been deprecated for removal in 3.0 and the next release.
4930
Amaury Forgeot d'Arc351ffb82008-08-18 19:23:47 +00004931- Issue #2234: distutils failed for some versions of the cygwin compiler. The
4932 version reported by these tools does not necessarily follow the python
4933 version numbering scheme, so the module is less strict when parsing it.
4934
Nick Coghlanf70385a2008-08-18 12:42:46 +00004935- Issue #2235: Added Py3k warnings for types which will become unhashable
4936 under the stricter __hash__ inheritance rules in 3.0. Several types
4937 which did not meet the rules for hash invariants and were already
4938 unhashable in 3.0 have now been explicitly flagged as unhashable in
4939 2.6 as well (collections.Mapping, collections.Set, unittest.TestSuite,
4940 xml.dom.minidom.NamedNodeMap, numbers.Number, UserList.UserList)
4941
Brett Cannon88f801d2008-08-18 00:46:22 +00004942- Update __all__ for cookielib, csv, os, urllib2, and weakref to include things
4943 imported into the module but exposed as part of the module's API.
4944
Brett Cannon7b96f072008-08-18 00:41:11 +00004945- Remove an unneeded import of abc.ABCMeta from 'inspect'.
4946
Brett Cannon46225e72008-08-18 00:36:52 +00004947- Remove unneeded imports of 'sys' and 'warnings' from 'io'.
4948
Brett Cannon25c9d6a2008-08-17 22:10:11 +00004949- Remove unneeded imports of 'warnings' from shelve, filecmp, and dummy_thread.
4950
Hirokazu Yamamoto41a81eb2008-08-17 13:10:46 +00004951- Issue #3575: Incremental decoder's decode function now takes bytearray
4952 by using 's*' instead of 't#'.
4953
Mark Dickinson3e4caeb2009-02-21 20:27:01 +00004954- Issue #2222: Fixed reference leak when occurred os.rename()
Hirokazu Yamamoto7f30a682008-08-17 09:46:56 +00004955 fails unicode conversion on 2nd parameter. (windows only)
4956
Georg Brandl222e2082010-08-01 22:27:39 +00004957- Issue #2464: urllib2 now supports a malformation in the URL received
Facundo Batista94f243a2008-08-17 03:38:39 +00004958 in a redirect.
4959
Brett Cannonabe423e2008-08-16 21:47:07 +00004960- Silence the DeprecationWarning raised when importing mimetools in
Brett Cannon721b1452008-08-16 22:00:27 +00004961 BaseHTTPServer, cgi (and rfc822), httplib.
Brett Cannonabe423e2008-08-16 21:47:07 +00004962
Facundo Batistaeb90b782008-08-16 14:44:07 +00004963- Issue #2776: fixed small issue when handling an URL with double slash
4964 after a 302 response in the case of not going through a proxy.
4965
Antoine Pitroub90a8be2008-08-15 21:03:21 +00004966- Issue #2676: in the email package, content-type parsing was hanging on
4967 pathological input because of quadratic or exponential behaviour of a
4968 regular expression.
4969
Antoine Pitrou11ec65d2008-08-14 21:04:30 +00004970- Issue #3476: binary buffered reading through the new "io" library is now
4971 thread-safe.
4972
Brett Cannonbf3157b2008-08-14 05:00:03 +00004973- Silence the DeprecationWarning of rfc822 when it is imported by mimetools
4974 since mimetools itself is deprecated. Because modules are cached, all
4975 subsequent imports of rfc822 will not raise a visible DeprecationWarning.
4976
Antoine Pitrou9fcd4b32008-08-11 17:21:36 +00004977- Issue #3134: shutil referenced undefined WindowsError symbol.
4978
Robert Schuppenies14646332008-08-10 11:01:53 +00004979- Issue #1342811: Fix leak in Tkinter.Menu.delete. Commands associated to
4980 menu entries were not deleted.
4981
Brett Cannon83e81842008-08-09 23:30:55 +00004982- Copied the implementation of reduce() to _functools.reduce() to have a
4983 version that did not raise a DeprecationWarning under -3.
4984
Antoine Pitrou76b8bee2008-08-09 17:27:23 +00004985- Issue #3205: When iterating over a BZ2File fails allocating memory, raise
4986 a MemoryError rather than silently stop the iteration.
4987
Guido van Rossum59ce9012008-08-09 14:55:34 +00004988- Issue #3487: sre "bytecode" validator. Passing invalid "re-bytecode"
4989 to _sre.compile() will now be rejected. This should not affect anybody
4990 since the re.compile() function never generates invalid re-bytecode.
4991
Skip Montanaroa032bf42008-08-08 22:52:51 +00004992- Issue #3436: Make csv.DictReader's fieldnames attribute a property so that
4993 upon first access it can be automatically initialized from the csv file if
4994 it wasn't initialized during instantiation.
4995
Brett Cannon3aa2a492008-08-06 22:28:09 +00004996- Issue #2338: Create imp.reload() to help with transitioning to Python 3.0 as
4997 the reload() built-in has been removed.
4998
Brett Cannon7e30b672008-08-04 21:52:25 +00004999- Changed code in the following modules/packages to remove warnings raised
Brett Cannonc1b76e42008-08-09 23:06:16 +00005000 while running under the ``-3`` flag: aifc, asynchat, asyncore, bdb, bsddb,
Brett Cannon047e4a92008-08-17 04:16:04 +00005001 ConfigParser, cookielib, csv, difflib, distutils, DocXMLRPCServer, email,
5002 filecmp, fileinput, inspect, logging, modulefinder, pdb, pickle, profile,
5003 pstats, pydoc, re, rlcompleter, SimpleXMLRPCServer, shelve, socket,
5004 subprocess, sqlite3, tarfile, Tkinter, test.test_support, textwrap,
5005 threading, tokenize, traceback, urlparse, wsgiref, xml, xmlrpclib.
Brett Cannon7e30b672008-08-04 21:52:25 +00005006
Lars Gustäbel727bd0b2008-08-02 11:26:39 +00005007- Issue #3039: Fix tarfile.TarFileCompat.writestr() which always
5008 raised an AttributeError.
5009
Benjamin Peterson01a24322008-07-28 23:35:27 +00005010- Issue #2523: Fix quadratic behaviour when read()ing a binary file without
Antoine Pitroude781a42008-08-09 12:43:23 +00005011 asking for a specific length. This problem only affected files opened
5012 using the new "io" module, not the built-in open() function.
Benjamin Peterson01a24322008-07-28 23:35:27 +00005013
Mark Dickinsonfe84cce2008-07-27 06:39:07 +00005014- Issue #3449: Update decimal module to use most recent specification
5015 (v. 1.68) and tests (v. 2.58) from IBM.
5016
Georg Brandl222e2082010-08-01 22:27:39 +00005017- Issue #3437: Bug fix in robotparser parsing of Allow: lines.

5021
Georg Brandlf9efabb2008-07-23 15:16:45 +00005022- Deprecate the "ast" parser function aliases.
5023
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00005024- Issue #3120: On 64-bit Windows the subprocess module was truncating handles.
5025
5026- Issue #3303: Fix a crash in locale.strcoll() when calling it with
5027 invalid arguments.
5028
5029- Issue #3302: Fix several crashes when calling locale's gettext functions
5030 with None arguments.
5031
5032- Issue #3389: Allow resolving dotted names for handlers in logging
5033 configuration files.
5034

5036
Antoine Pitrou5fdfa3e2008-07-25 19:42:26 +00005037- Issue #3394: zipfile.writestr sets external attributes when passed a
5038 file name rather than a ZipInfo instance, so files are extracted with
5039 mode 0600 rather than 000 under Unix.
5040
Gregory P. Smitha36f8fe2008-08-04 00:13:29 +00005041- Issue #1857: subprocess.Popen.poll gained an additional _deadstate keyword
5042 argument in python 2.5, this broke code that subclassed Popen to include its
5043 own poll method. Fixed my moving _deadstate to an _internal_poll method.

Nick Coghlan2a0c2b12008-08-04 12:47:17 +00005050Documentation
5051-------------
5052
Nick Coghlan6e8fef02008-08-18 13:14:22 +00005053- Issue #2235: the C API function PyObject_HashNotImplemented and its
5054 interaction with the tp_hash slot (added in 2.6b2) are now documented
5055
Nick Coghlan2a0c2b12008-08-04 12:47:17 +00005056- Issue #643841: The language reference now provides more detailed
5057 coverage of the lookup process for special methods. The disclaimers
5058 regarding lack of coverage of new-style classes have also been
5059 removed, since the coverage is now fairly reasonable.

Raymond Hettingere3ae6552008-06-20 04:18:15 +00005062What's New in Python 2.6 beta 2?
5063================================
5064
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00005065*Release date: 17-Jul-2008*
5066
Raymond Hettingere3ae6552008-06-20 04:18:15 +00005067Core and Builtins
5068-----------------
5069
Georg Brandl3e483f62008-07-16 22:57:41 +00005070- Issue #3156: Fix inconsistent behavior of the bytearray type: all
5071 its methods now allow for items objects that can be converted to
5072 an integer using operator.index().
5073
Mark Dickinson64b7e502008-07-16 09:40:03 +00005074- Issue #3360: Fix incorrect parsing of '020000000000.0', which
5075 produced a ValueError instead of giving the correct float.
5076
Eric Smitha5fa5a22008-07-16 00:11:49 +00005077- Issue #3083: Add alternate (#) formatting for bin, oct, hex output
5078 for str.format(). This adds the prefix 0b, 0o, or 0x, respectively.
5079
Mark Dickinson7103aa42008-07-15 19:08:33 +00005080- Issue #3008: the float type has a new instance method 'float.hex'
5081 and a new class method 'float.fromhex' to convert floating-point
5082 numbers to and from hexadecimal strings, respectively.
5083
Nick Coghlan6d6bd442008-07-15 15:40:22 +00005084- Issue #2235: __hash__ is once again inherited by default. To allow
5085 collections.Hashable to remain meaningful in the presence of the
5086 default hash implementation (object.__hash__), it is now possible
5087 to explicit block inheritance of hash by setting __hash__=None at
5088 the Python level, or tp_hash=PyObject_HashNotImplemented at the C
5089 level.
5090
Nick Coghlanb028f502008-07-13 14:52:36 +00005091- Issue #3221: Issue a RuntimeWarning instead of raising SystemError if
5092 the parent module cannot be found while performing an absolute import.
5093 This means that an incorrectly defined __package__ attribute will
5094 now only prevent relative imports in that module rather than causing
5095 all imports from that module to fail.
5096
Nick Coghlan14ff9942008-07-08 14:21:42 +00005097- Issue #2517: Allow unicode messages in Exceptions again by correctly
5098 bypassing the instance dictionary when looking up __unicode__ on
5099 new-style classes.
5100
Amaury Forgeot d'Arcbdd941f2008-07-01 20:38:04 +00005101- Issue #3242: Fix a crash inside the print statement, if sys.stdout is
5102 set to a custom object whose write() method happens to install
5103 another file in sys.stdout.
5104
Amaury Forgeot d'Arc1f40c8a2008-06-30 22:42:40 +00005105- Issue #3088: Corrected a race condition in classes derived from
5106 threading.local: the first member set by a thread could be saved in
5107 another thread's dictionary.
5108
Mark Dickinson1ec2fcd2008-06-20 14:53:43 +00005109- Issue #3004: Minor change to slice.indices(): the start and stop
5110 arguments are now treated identically, making the behaviour easier
5111 to describe and understand. For example, slice(None, -10,
5112 1).indices(9) now returns (0, 0, 1) instead of (0, -1, 1), and
5113 slice(None, 10, -1).indices(10) returns (9, 9, -1) instead of (9,

Georg Brandl5cc774e2008-06-11 20:28:06 +00005568 PPC64 and x86_64 support in one binary).
Ronald Oussoren5640ce22008-06-05 12:58:24 +00005569
5570 This is controlled by the configure argument ``--with-universal-archs``:
5571

5573
5574 - ``--with-universal-archs=32-bit``: install 2-way universal, 32-bit (the default)
5575
5576 - ``--with-universal-archs=64-bit``: install 2-way universal, 64-bit
5577

5617 two handlers that derive the same default base class.
Amaury Forgeot d'Arc96865852008-04-22 21:14:41 +00005618
Christian Heimese74c8f22008-04-19 02:23:57 +00005619- Added kill, terminate and send_signal(sig) to subprocess.Popen.
5620

Georg Brandl3ee81df2008-05-17 18:14:43 +00005630- Issue #1631171: Re-implement the 'warnings' module in C (the
5631 original Python code has been kept as backup). This will allow for
5632 using the 'warning's machinery in such places as the parser where
5633 use of pure Python code is not possible. Both the ``showarning()``
5634 and ``formatwarning()`` gain an optional 'line' argument which is
5635 not called by default for backwards-compatibility reasons. Setting
5636 ``warnings.showwarning()`` to an implementation that lacks support
5637 for the ``line`` argument will raise a DeprecationWarning.

5661
Gregory P. Smithd59fefb2008-04-22 08:11:33 +00005662- The getpass module has been improved on Unix. It now uses /dev/tty

Georg Brandl3ee81df2008-05-17 18:14:43 +00005700- Issue #2550: The approach used by client/server code for obtaining
5701 ports to listen on in network-oriented tests has been refined in an
5702 effort to facilitate running multiple instances of the entire
5703 regression test suite in parallel without issue.
5704 test_support.bind_port() has been fixed such that it will always
5705 return a unique port -- which wasn't always the case with the
5706 previous implementation, especially if socket options had been set
5707 that affected address reuse (i.e. SO_REUSEADDR, SO_REUSEPORT). The
5708 new implementation of bind_port() will actually raise an exception
5709 if it is passed an AF_INET/SOCK_STREAM socket with either the
5710 SO_REUSEADDR or SO_REUSEPORT socket option set. Furthermore, if
5711 available, bind_port() will set the SO_EXCLUSIVEADDRUSE option on
5712 the socket it's been passed. This currently only applies to
5713 Windows. This option prevents any other sockets from binding to the
5714 host/port we've bound to, thus removing the possibility of the
5715 'non-deterministic' behaviour, as Microsoft puts it, that occurs
5716 when a second SOCK_STREAM socket binds and accepts to a host/port
5717 that's already been bound by another socket. The optional preferred
5718 port parameter to bind_port() has been removed. Under no
5719 circumstances should tests be hard coding ports!
5720
5721 test_support.find_unused_port() has also been introduced, which will
5722 pass a temporary socket object to bind_port() in order to obtain an
5723 unused port. The temporary socket object is then closed and
5724 deleted, and the port is returned. This method should only be used
5725 for obtaining an unused port in order to pass to an external program
5726 (i.e. the -accept [port] argument to openssl's s_server mode) or as
5727 a parameter to a server-oriented class that doesn't give you direct
5728 access to the underlying socket used.
5729
5730 Finally, test_support.HOST has been introduced, which should be used
5731 for the host argument of any relevant socket calls (i.e. bind and
5732 connect).
Trent Nelsone41b0062008-04-08 23:47:30 +00005733
5734 The following tests were updated to following the new conventions:
Georg Brandl3ee81df2008-05-17 18:14:43 +00005735 test_socket, test_smtplib, test_asyncore, test_ssl, test_httplib,
Trent Nelsone41b0062008-04-08 23:47:30 +00005736 test_poplib, test_ftplib, test_telnetlib, test_socketserver,
5737 test_asynchat and test_socket_ssl.
5738
Georg Brandl3ee81df2008-05-17 18:14:43 +00005739 It is now possible for multiple instances of the regression test
5740 suite to run in parallel without issue.

Eric Smitha73fbe72008-02-23 03:09:44 +00006019- Added the future_builtins module, which contains hex() and oct().
6020 These are the PEP 3127 version of these functions, designed to be
6021 compatible with the hex() and oct() builtins from Python 3.0. They
6022 differ slightly in their output formats from the existing, unchanged
6023 Python 2.6 builtins. The expected usage of the future_builtins
6024 module is:
6025 from future_builtins import hex, oct
6026
Eric Smith7ef40bf2008-02-20 23:34:22 +00006027- Issue #1600: Modifed PyOS_ascii_formatd to use at most 2 digit
6028 exponents for exponents with absolute value < 100. Follows C99
6029 standard. This is a change on Windows, which would use 3 digits.
6030 Also, added 'n' to the formats that PyOS_ascii_formatd understands,
6031 so that any alterations it does to the resulting string will be
6032 available in stringlib/formatter.h (for float.__format__).
6033
Eric Smith5a3c1352008-02-19 13:21:56 +00006034- Implemented PEP 3101, Advanced String Formatting. This adds a new
6035 builtin format(); a format() method for str and unicode; a
6036 __format__() method to object, str, unicode, int, long, float, and
6037 datetime; the class string.Formatter; and the C API
6038 PyObject_Format().
6039
Georg Brandl3ee81df2008-05-17 18:14:43 +00006040- Fixed several potential crashes, all caused by specially crafted
6041 __del__ methods exploiting objects in temporarily inconsistent
6042 state.
Amaury Forgeot d'Arc632fad32008-02-16 20:55:24 +00006043
Vinay Sajipb7edfc42008-04-02 21:10:23 +00006044- Issue #2115: Important speedup in setting __slot__ attributes. Also
Georg Brandl3ee81df2008-05-17 18:14:43 +00006045 prevent a possible crash: an Abstract Base Class would try to access
6046 a slot on a registered virtual subclass.
Amaury Forgeot d'Arc60d6c7f2008-02-15 21:22:45 +00006047

Georg Brandl3ee81df2008-05-17 18:14:43 +00006051- Clear all free lists during a gc.collect() of the highest generation
6052 in order to allow pymalloc to free more arenas. Python may give back
6053 memory to the OS earlier.
Christian Heimes3b718a72008-02-14 12:47:33 +00006054
Georg Brandl3ee81df2008-05-17 18:14:43 +00006055- Issue #2045: Fix an infinite recursion triggered when printing a
6056 subclass of collections.defaultdict, if its default_factory is set
6057 to a bound method.
Amaury Forgeot d'Arcb01aa432008-02-08 00:56:02 +00006058
Christian Heimesf75dbef2008-02-08 00:11:31 +00006059- Fixed a minor memory leak in dictobject.c. The content of the free
6060 list was not freed on interpreter shutdown.
6061
Georg Brandl21e99f42010-03-07 15:23:59 +00006062- Limit free list of method and built-in function objects to 256
Georg Brandl3ee81df2008-05-17 18:14:43 +00006063 entries each.
Christian Heimes6075a822008-02-06 12:44:34 +00006064
Georg Brandl3ee81df2008-05-17 18:14:43 +00006065- Patch #1953: Added ``sys._compact_freelists()`` and the C API
6066 functions ``PyInt_CompactFreeList`` and ``PyFloat_CompactFreeList``
Christian Heimes422051a2008-02-04 18:00:12 +00006067 to compact the internal free lists of pre-allocted ints and floats.
6068
Georg Brandl3ee81df2008-05-17 18:14:43 +00006069- Issue #1983: Fixed return type of fork(), fork1() and forkpty()
6070 calls. Python expected the return type int but the fork familie
6071 returns pi_t.
Christian Heimes951cc0f2008-01-31 23:08:23 +00006072
Georg Brandl3ee81df2008-05-17 18:14:43 +00006073- Issue #1678380: Fix a bug that identifies 0j and -0j when they
6074 appear in the same code unit.
Mark Dickinson105be772008-01-31 22:17:37 +00006075

Georg Brandl3ee81df2008-05-17 18:14:43 +00006085- Patch #1473257: generator objects gain a gi_code attribute. This is
6086 the same object as the func_code attribute of the function that
6087 produced the generator.
Georg Brandl0cdf9a32008-01-26 14:14:20 +00006088
Georg Brandl3ee81df2008-05-17 18:14:43 +00006089- Issue #1920: "while 0" statements were completely removed by the
6090 compiler, even in the presence of an "else" clause, which is
6091 supposed to be run when the condition is false. Now the compiler
6092 correctly emits bytecode for the "else" suite.
Amaury Forgeot d'Arc31eaafe2008-01-24 22:59:25 +00006093
Guido van Rossumeead05f2008-01-24 18:21:02 +00006094- A few crashers fixed: weakref_in_del.py (issue #1377858);
6095 loosing_dict_ref.py (issue #1303614, test67.py);
6096 borrowed_ref_[34].py (not in tracker).
6097
Vinay Sajipd7cf32e2008-01-24 12:43:33 +00006098- Issue #1069410: The "can't load dll" message box on Windows is
Christian Heimesb2302ba2008-01-23 17:15:06 +00006099 suppressed while an extension is loaded by calling SetErrorMode in
6100 dynload_win.c. The error is still reported properly.
6101
Georg Brandl3ee81df2008-05-17 18:14:43 +00006102- Issue #1915: Python compiles with --enable-unicode=no again. However
Christian Heimes082c9b02008-01-23 14:20:50 +00006103 several extension methods and modules do not work without unicode
6104 support.
6105
Georg Brandl26543b12008-01-21 18:36:51 +00006106- Issue #1882: when compiling code from a string, encoding cookies in the
6107 second line of code were not always recognized correctly.
6108
Georg Brandl14404b62008-01-19 19:27:05 +00006109- Issue #1679: "0x" was taken as a valid integer literal.
6110
Georg Brandl6caad7d2008-01-26 14:19:22 +00006111- Issue #1865: ``bytes`` as an alias for ``str`` and b"" as an alias "" were
Christian Heimes288e89a2008-01-18 18:24:07 +00006112 added.
6113
Christian Heimesc94e2b52008-01-14 04:13:37 +00006114- sys.float_info / PyFloat_GetInfo: The floating point information
6115 object was converted from a dict to a specialized structseq object.
6116
Georg Brandl3ee81df2008-05-17 18:14:43 +00006117- Patch #1816: Added sys.flags structseq. It exposes the status of
6118 most command line arguments and PYTHON* environment variables.
Christian Heimesf31b69f2008-01-14 03:42:48 +00006119
Georg Brandl3ee81df2008-05-17 18:14:43 +00006120- Objects/structseq.c: Implemented new structseq representation. The

Georg Brandl3ee81df2008-05-17 18:14:43 +00006181- Patch #1739468: Directories and zipfiles containing a __main__.py
6182 file can now be directly executed by passing their name to the
6183 interpreter. The directory/zipfile is automatically inserted as the
6184 first entry in sys.path.

Georg Brandl3ee81df2008-05-17 18:14:43 +00006186- Issue #1265: Fix a problem with sys.settrace, if the tracing
6187 function uses a generator expression when at the same time the
6188 executed code is closing a paused generator.
Amaury Forgeot d'Arc0d75f092007-11-13 21:54:28 +00006189
Raymond Hettinger1760c8a2007-11-08 02:52:43 +00006190- sets and frozensets now have an isdisjoint() method.

6195
Georg Brandl21e99f42010-03-07 15:23:59 +00006196- The enumerate() built-in function is no longer bounded to sequences
Georg Brandl3ee81df2008-05-17 18:14:43 +00006197 smaller than LONG_MAX. Formerly, it raised an OverflowError. Now,
6198 automatically shifts from ints to longs.
Raymond Hettinger8f669372007-10-03 21:18:11 +00006199
Georg Brandl3ee81df2008-05-17 18:14:43 +00006200- Issue #1686386: Tuple's tp_repr did not take into account the
6201 possibility of having a self-referential tuple, which is possible
6202 from C code. Nor did object's tp_str consider that a type's tp_str
6203 could do something that could lead to an inifinite recursion.
6204 Py_ReprEnter() and Py_EnterRecursiveCall(), respectively, fixed the
6205 issues.
Brett Cannon0b14f242007-09-30 19:45:10 +00006206
Georg Brandl3ee81df2008-05-17 18:14:43 +00006207- Issue #1164: It was possible to trigger deadlock when using the
6208 'print' statement to write to a file since the GIL was not released
6209 as needed. Now PyObject_Print() does the right thing along with
6210 various tp_print implementations of the built-in types and those in
6211 the collections module.
Brett Cannon01531592007-09-17 03:28:34 +00006212
Georg Brandl3ee81df2008-05-17 18:14:43 +00006213- Issue #1147: Exceptions were directly allowing string exceptions in

6215 allowed.

Brett Cannona0c05512007-09-10 21:38:27 +00006219
Brett Cannon1e534b52007-09-07 04:18:30 +00006220- Issue #1202533: Fix infinite recursion calls triggered by calls to
Georg Brandl3ee81df2008-05-17 18:14:43 +00006221 PyObject_Call() never calling back out to Python code to trigger
6222 recursion depth updates/checks. Required the creation of a static
6223 RuntimeError instance in case normalizing an exception put the
6224 recursion check value past its limit. Fixes crashers
6225 infinite_rec_(1|2|4|5).py.
Brett Cannon1e534b52007-09-07 04:18:30 +00006226

Neal Norwitz0ac60192007-05-27 04:08:54 +00006240- Add new attribute names for function objects. All the func_* become
Georg Brandl3ee81df2008-05-17 18:14:43 +00006241 __*__ attributes. (Some already existed, e.g., __doc__ and
6242 __name__.)
Neal Norwitz0ac60192007-05-27 04:08:54 +00006243
Neal Norwitz8b2bfbc2007-05-23 06:35:32 +00006244- Add -3 option to the interpreter to warn about features that are
6245 deprecated and will be changed/removed in Python 3.0.
6246
Georg Brandl2134e752007-05-21 20:34:16 +00006247- Patch #1686487: you can now pass any mapping after '**' in function
6248 calls.
6249
Collin Winter62903052007-05-18 23:11:24 +00006250- except clauses may now be spelled either "except E, target:" or
Georg Brandl3ee81df2008-05-17 18:14:43 +00006251 "except E as target:". This is to provide forwards compatibility
6252 with Python 3.0.

Vinay Sajip8549ce32007-05-06 17:53:37 +00006259- When __slots__ are set to a unicode string, make it work the same as
Neal Norwitzcbd9ee62007-04-14 05:25:50 +00006260 setting a plain string, ie don't expand to single letter identifiers.
6261
Raymond Hettinger13936692007-04-11 18:40:58 +00006262- Request #1191699: Slices can now be pickled.
6263
Raymond Hettinger4db5fe92007-04-12 04:10:00 +00006264- Request #1193128: str.translate() now allows a None argument for
6265 translations that only remove characters without re-mapping the
6266 remaining characters.
6267
Georg Brandl5cb76c12007-03-21 09:00:39 +00006268- Patch #1682205: a TypeError while unpacking an iterable is no longer

6272
Guido van Rossum143b5642007-03-23 04:58:42 +00006273- Bug #1683368: The object.__init__() and object.__new__() methods are
6274 now stricter in rejecting excess arguments. The only time when
6275 either allows excess arguments is when it is not overridden and the
6276 other one is. For backwards compatibility, when both are
6277 overridden, it is a deprecation warning (for now; maybe a Py3k
Guido van Rossum234b1ff2007-03-23 19:39:01 +00006278 warning later). Also, type.__init__() insists on the same signature
6279 as supported by type.__new__().
Guido van Rossum143b5642007-03-23 04:58:42 +00006280
Georg Brandl3ee81df2008-05-17 18:14:43 +00006281- Patch #1675423: PyComplex_AsCComplex() now tries to convert an
6282 object to complex using its __complex__() method before falling back
6283 to the __float__() method. Therefore, the functions in the cmath
6284 module now can operate on objects that define a __complex__()
6285 method.
Georg Brandl2b869942007-03-17 16:08:45 +00006286
Georg Brandl3ee81df2008-05-17 18:14:43 +00006287- Patch #1623563: allow __class__ assignment for classes with

6289 same slot names.
Žiga Seilnacht6f2d09c2007-03-16 11:59:38 +00006290

6296 its type.

6302
Georg Brandl7b9c5552007-03-12 14:30:05 +00006303- Bug #1678647: write a newline after printing an exception in any
6304 case, even when converting the value to a string failed.
6305
Georg Brandl871f1bc2007-03-12 13:17:36 +00006306- The dir() function has been extended to call the __dir__() method on
Georg Brandl3ee81df2008-05-17 18:14:43 +00006307 its argument, if it exists. If not, it will work like before. This
6308 allows customizing the output of dir() in the presence of a
6309 __getattr__().

Georg Brandl3ee81df2008-05-17 18:14:43 +00006317- Patch #1491866: change the complex() constructor to allow
6318 parthensized forms. This means complex(repr(x)) now works instead of
6319 raising a ValueError.
Collin Wintere38051d2007-03-09 20:33:07 +00006320
Georg Brandlaa2321b2007-03-07 00:40:28 +00006321- Patch #703779: unset __file__ in __main__ after running a file. This
Georg Brandl3ee81df2008-05-17 18:14:43 +00006322 makes the filenames the warning module prints much more sensible
6323 when a PYTHONSTARTUP file is used.
Georg Brandlaa2321b2007-03-07 00:40:28 +00006324

Georg Brandl0fca97a2007-03-05 22:28:08 +00006336- Patch #1674228: when assigning a slice (old-style), check for the
6337 sq_ass_slice instead of the sq_slice slot.
6338
Georg Brandl3ee81df2008-05-17 18:14:43 +00006339- When printing an unraisable error, don't print exceptions. before
6340 the name. This duplicates the behavior whening normally printing
6341 exceptions.

Georg Brandl92a6bae2007-03-13 17:43:32 +00006908- Patch #1603688: ConfigParser.SafeConfigParser now checks values that
Georg Brandl3ee81df2008-05-17 18:14:43 +00006909 are set for invalid interpolation sequences that would lead to

6966 TestCase and TestSuite subclasses (not instances) are no longer
6967 accepted in TestSuite.addTest(). This should cause no
6968 incompatibility since it never made sense with ordinary subclasses
6969 -- the failure just occurred later, with a more cumbersome
6970 exception.

Georg Brandl3ee81df2008-05-17 18:14:43 +00007251- Issue #829951: In the smtplib module, SMTP.starttls() now complies
7252 with RFC 3207 and forgets any knowledge obtained from the server not
7253 obtained from the TLS negotiation itself. Patch contributed by Bill
7254 Fenner.
Gregory P. Smith2b3ba582008-01-17 08:03:17 +00007255
Georg Brandl3ee81df2008-05-17 18:14:43 +00007256- Issue #1339: The smtplib.SMTP class has been refactored a bit such
Gregory P. Smithbde4ae42008-01-17 08:35:49 +00007257 that the SMTP.starttls() caller no longer needs to call ehlo()
7258 beforehand. SMTP.starttls() now raises an exception of the server
Georg Brandl3ee81df2008-05-17 18:14:43 +00007259 does not claim to support starttls. Adds the
7260 SMTP.ehlo_or_helo_if_needed() method. Patch contributed by Bill
7261 Fenner.

Georg Brandl3ee81df2008-05-17 18:14:43 +00007315- itertools.chain() now has an alternate constructor,

7341 complex, tuple, list, dict, set, and frozenset. Formerly, it would
7342 silently miscode subclasses of those types. Now, it raises a
7343 ValueError instead.
Raymond Hettinger12e94202007-11-07 01:13:09 +00007344

Georg Brandl3ee81df2008-05-17 18:14:43 +00007359 time so that opening a database previously created with the DB_DUP
7360 or DB_DUPSORT flag set will keep the proper behavior on subsequent
7361 opens. Specifically: dictionary assignment to a DB object will
7362 replace all values for a given key when the database allows
7363 duplicate values. DB users should use DB.put(k, v) when they want
7364 to store duplicates; not DB[k] = v.
Gregory P. Smithec10a4a2007-11-05 02:32:26 +00007365

7371 characters with ASCII value less than 32. Also, it correctly quotes
7372 dots only if they occur on a single line, as opposed to the previous
7373 behavior of quoting dots if they are the second character of any
7374 line.
Georg Brandl4aef7272007-03-13 22:49:43 +00007375

Guido van Rossum7c862f82007-12-13 20:50:10 +00007637- Bug #1608: use -fwrapv when GCC supports it. This is important,
7638 newer GCC versions may optimize away overflow buffer overflow checks
7639 without this option!
7640
Martin v. Löwis63bf1492007-11-12 05:14:05 +00007641- Patch #1418: Make the AC_REPLACE_FUNCS object files actually work.
7642
Raymond Hettingerdc1d1ba2007-11-07 02:45:46 +00007643- Add a FAST_LOOPS build option that speeds-up looping by trading away
Georg Brandl3ee81df2008-05-17 18:14:43 +00007644 periodic threadstate and signal checking in tight loops. By
7645 default, this option is turned-off. It should only be enabled in
7646 debugged, performance critical applications.

7662 returned by python-config if Python was built with --enable-shared
7663 because that prevented the shared library from being used.
7664

7697-----
7698
Georg Brandl3ee81df2008-05-17 18:14:43 +00007699- Unified naming convention for free lists and their limits. All free
7700 lists in Object/ are named ``free_list``, the counter ``numfree``
7701 and the upper limit is a macro ``PyName_MAXFREELIST`` inside an
7702 #ifndef block.
Christian Heimes5b970ad2008-02-06 13:33:44 +00007703
Georg Brandl3ee81df2008-05-17 18:14:43 +00007704- ``PySet_Add()`` can now modify a newly created frozenset. Similarly
7705 to ``PyTuple_SetItem``, it can be used to populate a brand new
7706 frozenset; but it does not steal a reference to the added item.
Amaury Forgeot d'Arccab3d982008-02-03 22:51:43 +00007707

7715
7716- Issue #1534: Added ``PyFloat_GetMax()``, ``PyFloat_GetMin()`` and
7717 ``PyFloat_GetInfo()`` to the float API.
7718
Georg Brandl3ee81df2008-05-17 18:14:43 +00007719- Issue #1521: On 64bit platforms, using PyArgs_ParseTuple with the t#
7720 of w# format code incorrectly truncated the length to an int, even
7721 when PY_SSIZE_T_CLEAN is set. The str.decode method used to return
7722 incorrect results with huge strings.
Georg Brandl6caad7d2008-01-26 14:19:22 +00007723
Georg Brandl3ee81df2008-05-17 18:14:43 +00007724- Issue #1629: Renamed Py_Size, Py_Type and Py_Refcnt to Py_SIZE,

7742- Fix some leftovers from the conversion from int to Py_ssize_t
7743 (relevant to strings and sequences of more than 2**31 items).
7744
7745- Make _PyGILState_NoteThreadState() static, it was not used anywhere
7746 outside of pystate.c and should not be necessary.
7747
Georg Brandl3ee81df2008-05-17 18:14:43 +00007748- ``PyImport_Import`` and ``PyImport_ImportModule`` now always do
7749 absolute imports. In earlier versions they might have used relative
7750 imports under some conditions.
Christian Heimes000a0742008-01-03 22:16:32 +00007751
Georg Brandl3ee81df2008-05-17 18:14:43 +00007752- Added case insensitive comparison methods ``PyOS_stricmp(char*,
7753 char*)`` and ``PyOS_strnicmp(char*, char*, Py_ssize_t)``.
Christian Heimes000a0742008-01-03 22:16:32 +00007754
Georg Brandl3ee81df2008-05-17 18:14:43 +00007755- Bug #1542693: remove semi-colon at end of PyImport_ImportModuleEx

7763 requires Windows 2000 or greater. The _WINVER and NTDDI_VERSION
7764 macros are set to Win2k for x86/32bit builds and WinXP for AMD64
7765 builds.
Christian Heimes95d64472008-02-09 19:55:22 +00007766

Georg Brandl3ee81df2008-05-17 18:14:43 +00007780- Removed the macfs module. It had been deprecated since Python 2.5.
7781 This lead to the deprecation of macostools.touched() as it relied
7782 solely on macfs and was a no-op under OS X.
