14
Mark Dickinson4ca7c3c2010-05-30 13:18:10 +000015- Issue #8748: Fix two issues with comparisons between complex and integer
16 objects. (1) The comparison could incorrectly return True in some cases
17 (2**53+1 == complex(2**53) == 2**53), breaking transivity of equality.
18 (2) The comparison raised an OverflowError for large integers, leading
19 to unpredictable exceptions when combining integers and complex objects
20 in sets or dicts.
21
Mark Dickinson81336372010-05-30 12:12:25 +000022- Issue #5211: Implicit coercion for the complex type is now completely
23 removed. (Coercion for arithmetic operations was already removed in 2.7
24 alpha 4, but coercion for rich comparisons was accidentally left in.)
25
Victor Stinnerc49dfcc2010-05-25 22:30:32 +000026- Issue #3798: Write sys.exit() message to sys.stderr to use stderr encoding
27 and error handler, instead of writing to the C stderr file in utf-8
28

Georg Brandlfee0f442010-05-22 21:26:21 +000032- Issue #7079: Fix a possible crash when closing a file object while using it
33 from another thread. Patch by Daniel Stutzbach.

Ronald Oussoren27c72e92010-06-02 03:47:14 +000035- Issue #8868: Fix that ensures that python scripts have access to the
36 Window Server again in a framework build on MacOSX 10.5 or earlier.

Georg Brandlfee0f442010-05-22 21:26:21 +000041- Issue #5753: A new C API function, :cfunc:`PySys_SetArgvEx`, allows embedders
42 of the interpreter to set sys.argv without also modifying sys.path. This
43 helps fix `CVE-2008-5983
Antoine Pitrou6a265602010-05-21 17:12:38 +000044 <http://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2008-5983>`_.

50 mistake.
51
R. David Murray52dcd452010-06-02 22:03:15 +000052- Issue #1368247: set_charset (and therefore MIMEText) now automatically
53 encodes a unicode _payload to the output_charset.
54
Alexander Belopolsky9292ee02010-05-27 20:55:27 +000055- Issue #7150: Raise OverflowError if the result of adding or subtracting

Georg Brandlfee0f442010-05-22 21:26:21 +0000125- Issue #1533: Fix inconsistency in range function argument processing: any
126 non-float non-integer argument is now converted to an integer (if possible)
127 using its __int__ method. Previously, only small arguments were treated this
128 way; larger arguments (those whose __int__ was outside the range of a C long)
129 would produce a TypeError.

Georg Brandlfee0f442010-05-22 21:26:21 +0000137 ``PyMarshal_ReadLastObjectFromFile``, which doesn't bring any noticeable
Antoine Pitrou18e63fb2010-04-21 22:53:29 +0000138 benefit compared to the dynamic memory allocation fallback. Patch by
139 Charles-François Natali.

180 operation raises multiple signals and more than one of those signals is
181 trapped, the specification determines the order in which the signals should be
182 handled. In many cases this order wasn't being followed, leading to the wrong

Mark Dickinsond2f3e3f2010-05-05 22:23:58 +0000328 (Optimization was unintentionally turned on in gcc --with-pydebug builds in
329 2.7 beta1 as a result of the issue #1628484 fix, combined with autoconf's
330 strange choice of default CFLAGS produced by AC_PROG_CC for gcc.)

350Core and Builtins
351-----------------
352
Philip Jenveyaebbaeb2010-04-06 23:24:45 +0000353- Issue #7301: Add environment variable $PYTHONWARNINGS.
354
Benjamin Peterson3a1dfa22010-04-06 21:50:00 +0000355- Issue #8329: Don't return the same lists from select.select when no fds are
356 changed.
357
Georg Brandlfee0f442010-05-22 21:26:21 +0000358- Issue #8259: ``1L << (2**31)`` no longer produces an 'outrageous shift error'
Mark Dickinson82791672010-04-06 16:47:55 +0000359 on 64-bit machines. The shift count for either left or right shift is
360 permitted to be up to sys.maxsize.
361
Benjamin Peterson4ceeeb02010-04-03 22:48:51 +0000362- Ensure that tokenization of identifiers is not affected by locale.

367
Georg Brandlfee0f442010-05-22 21:26:21 +0000368- Issue #7994: Issue a PendingDeprecationWarning if object.__format__ is called
369 with a non-empty format string. This is an effort to future-proof user
370 code. If a derived class does not currently implement __format__ but later
371 adds its own __format__, it would most likely break user code that had
372 supplied a format string. This will be changed to a DeprecationWaring in
373 Python 3.3 and it will be an error in Python 3.4.
Eric Smithd44b2fc2010-04-02 12:30:56 +0000374
Antoine Pitroua57df2c2010-03-31 21:32:15 +0000375- Issue #8268: Old-style classes (not just instances) now support weak

Antoine Pitrouf9de5342010-04-05 21:35:07 +0000400- Issue #8321: Give access to OpenSSL version numbers from the `ssl` module,
Georg Brandlfee0f442010-05-22 21:26:21 +0000401 using the new attributes `ssl.OPENSSL_VERSION`, `ssl.OPENSSL_VERSION_INFO` and

405
Georg Brandlfee0f442010-05-22 21:26:21 +0000406- Issue #8257: The Decimal construct now accepts a float instance directly,
407 converting that float to a Decimal of equal value:
Mark Dickinson8a950712010-04-03 15:47:46 +0000408
409 >>> Decimal(1.1)
410 Decimal('1.100000000000000088817841970012523233890533447265625')
411
Raymond Hettinger34c35b22010-04-03 10:22:00 +0000412- collections.Counter() now supports a subtract() method.
413
Georg Brandlfee0f442010-05-22 21:26:21 +0000414- The functools module now has a total_ordering() class decorator to simplify
415 the specification of rich comparisons.
Raymond Hettingera551f312010-04-04 18:34:45 +0000416
Georg Brandlfee0f442010-05-22 21:26:21 +0000417- The functools module also adds cmp_to_key() as a tool to transition old-style

Georg Brandlfee0f442010-05-22 21:26:21 +0000420- Issue #8294: The Fraction constructor now accepts Decimal and float instances
421 directly.
Mark Dickinson7c63eee2010-04-02 22:27:36 +0000422
Georg Brandlfee0f442010-05-22 21:26:21 +0000423- Issue #7279: Comparisons involving a Decimal signaling NaN now signal
424 InvalidOperation instead of returning False. (Comparisons involving a quiet
425 NaN are unchanged.) Also, Decimal quiet NaNs are now hashable; Decimal
426 signaling NaNs remain unhashable.
Mark Dickinsone096e822010-04-02 10:17:07 +0000427
Georg Brandlfee0f442010-05-22 21:26:21 +0000428- Issue #2531: Comparison operations between floats and Decimal instances now
429 return a result based on the numeric values of the operands; previously they
430 returned an arbitrary result based on the relative ordering of id(float) and
431 id(Decimal).
Mark Dickinson99d80962010-04-02 08:53:22 +0000432
Barry Warsawf7f2d6f2010-03-31 21:07:16 +0000433- Issue #8233: When run as a script, py_compile.py optionally takes a single
Georg Brandlfee0f442010-05-22 21:26:21 +0000434 argument `-` which tells it to read files to compile from stdin. Each line is
435 read on demand and the named file is compiled immediately. (Original patch by
436 Piotr Ożarowski).
Barry Warsawf7f2d6f2010-03-31 21:07:16 +0000437
Georg Brandlfee0f442010-05-22 21:26:21 +0000438- Issue #3135: Add ``inspect.getcallargs()``, which binds arguments to a

Georg Brandlfee0f442010-05-22 21:26:21 +0000445- Comparisons using one of <, <=, >, >= between a complex instance and a
446 Fractions instance now raise TypeError instead of returning True/False. This
447 makes Fraction <=> complex comparisons consistent with int <=> complex, float
448 <=> complex, and complex <=> complex comparisons.

Vinay Sajipecfa08f2010-03-12 09:16:10 +0000503- Issue #8117: logging: Improved algorithm for computing initial rollover time
Georg Brandlfee0f442010-05-22 21:26:21 +0000504 for ``TimedRotatingFileHandler`` by using the modification time of an existing
505 log file to compute the next rollover time. If the log file does not exist,
506 the current time is used as the basis for the computation.

Mark Dickinson4846a8e2010-04-03 14:05:10 +0000547- Issue #8300: When passing a non-integer argument to struct.pack with any
548 integer format code, struct.pack first attempts to convert the non-integer
549 using its __index__ method. If that method is non-existent or raises
550 TypeError it goes on to try the __int__ method, as described below.
551
Georg Brandlba83f822010-03-14 09:50:54 +0000552- Issue #1530559: When passing a non-integer argument to struct.pack with *any*
553 integer format code (one of 'bBhHiIlLqQ'), struct.pack attempts to use the
554 argument's __int__ method to convert to an integer before packing. It also
Georg Brandlfee0f442010-05-22 21:26:21 +0000555 produces a DeprecationWarning in this case. (In Python 2.6, the behaviour was
556 inconsistent: __int__ was used for some integer codes but not for others, and
557 the set of integer codes for which it was used differed between native packing
558 and standard packing.)

799 and add the additional members returned in an OSVERSIONINFOEX structure. The
800 new members are service_pack_major, service_pack_minor, suite_mask, and
801 product_type.

Georg Brandlba83f822010-03-14 09:50:54 +0000803- Issue #7561: Operations on empty bytearrays (such as ``int(bytearray())``)
804 could crash in many places because of the ``PyByteArray_AS_STRING()`` macro
805 returning NULL. The macro now returns a statically allocated empty string
806 instead.

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

Antoine Pitrouf3fa0742010-01-31 22:26:04 +0000855- Issue #6939: Fix file I/O objects in the `io` module to keep the original
Georg Brandlba83f822010-03-14 09:50:54 +0000856 file position when calling `truncate()`. It would previously change the file
857 position to the given argument, which goes against the tradition of
Antoine Pitrouf3fa0742010-01-31 22:26:04 +0000858 ftruncate() and other truncation APIs. Patch by Pascal Chambon.
859
Benjamin Petersone06f7112010-01-28 02:15:02 +0000860- UserDict is now a new-style class.
861
Georg Brandlba83f822010-03-14 09:50:54 +0000862- Issue #7610: Reworked implementation of the internal ``zipfile.ZipExtFile``
863 class used to represent files stored inside an archive. The new
864 implementation is significantly faster and can be wrapped in a
865 ``io.BufferedReader`` object for more speedups. It also solves an issue
866 where interleaved calls to ``read()`` and ``readline()`` give wrong results.
867 Patch by Nir Aides.

875 when the release file is empty.
Benjamin Petersona43f34c2010-01-25 03:31:13 +0000876
Georg Brandlba83f822010-03-14 09:50:54 +0000877- Issue #7748: Since unicode values are supported for some metadata options in
878 Distutils, the DistributionMetadata get_* methods will now return an utf-8
879 encoded string for them. This ensures that the upload and register commands
880 send the correct values to PyPI without any error.

954Core and Builtins
955-----------------
956
Georg Brandlba83f822010-03-14 09:50:54 +0000957- The ``__complex__()`` method is now looked up on the class of instances to
958 make it consistent with other special methods.

Antoine Pitrou5b7139a2010-01-02 21:12:58 +0000960- Issue #7462: Implement the stringlib fast search algorithm for the `rfind`,
961 `rindex`, `rsplit` and `rpartition` methods. Patch by Florent Xicluna.
962
Mark Dickinson1b34d252010-01-01 17:27:30 +0000963- Issue #5080: A number of functions and methods previously produced a
Georg Brandlba83f822010-03-14 09:50:54 +0000964 DeprecationWarning when passed a float argument where an integer was expected.
965 These functions and methods now raise TypeError instead. The majority of the
966 effects of this change are in the extension modules, but some core functions
967 and methods are affected: notably the 'chr', 'range' and 'xrange' builtins,
968 and many unicode/str methods.

Georg Brandlba83f822010-03-14 09:50:54 +00001151- Issue #7117: ``repr(x)`` for a float x returns a result based on the shortest
1152 decimal string that's guaranteed to round back to x under correct rounding
1153 (with round-half-to-even rounding mode). Previously it gave a string based on
1154 rounding x to 17 decimal digits. repr(x) for a complex number behaves
1155 similarly. On platforms where the correctly-rounded strtod and dtoa code is
1156 not supported (see below), repr is unchanged.
Mark Dickinsonb678de82009-11-19 18:41:49 +00001157
Georg Brandlba83f822010-03-14 09:50:54 +00001158- Issue #7117: On almost all platforms: float-to-string and string-to-float
1159 conversions within Python are now correctly rounded. Places these conversions
1160 occur include: str for floats and complex numbers; the float and complex
1161 constructors; old-style and new-style numeric formatting; serialization and
1162 deserialization of floats and complex numbers using marshal, pickle and json;
1163 parsing of float and imaginary literals in Python code; Decimal-to-float
1164 conversion.
Mark Dickinsonb678de82009-11-19 18:41:49 +00001165
Georg Brandlba83f822010-03-14 09:50:54 +00001166 The conversions use a Python-adapted version of David Gay's well-known dtoa.c,
1167 providing correctly-rounded strtod and dtoa C functions. This code is
1168 supported on Windows, and on Unix-like platforms using gcc, icc or suncc as
1169 the C compiler. There may be a small number of platforms on which correct
1170 operation of this code cannot be guaranteed, so the code is not used: notably,
1171 this applies to platforms where the C double format is not IEEE 754 binary64,
1172 and to platforms on x86 hardware where the x87 FPU is set to 64-bit precision
1173 and Python's configure script is unable to determine how to change the FPU
1174 precision. On these platforms conversions use the platform strtod and dtoa,
1175 as before.

Georg Brandlba83f822010-03-14 09:50:54 +00001177- Issue #7117: Backport round implementation from Python 3.x. ``round()`` now
1178 uses the correctly-rounded string <-> float conversions described above (when
1179 available), and so produces correctly rounded results that will display nicely
1180 under the float repr. There are two related small changes: (1) round now
1181 accepts any class with an ``__index__()`` method for its second argument (but
1182 no longer accepts floats for the second argument), and (2) an excessively
1183 large second integer argument (e.g., ``round(1.234, 10**100)``) no longer
1184 raises an exception.

Georg Brandlba83f822010-03-14 09:50:54 +00001331- Issue #5920: For ``float.__format__()``, change the behavior with the empty
1332 presentation type (that is, not one of 'e', 'f', 'g', or 'n') to be like 'g'
1333 but with at least one decimal point and with a default precision
1334 of 12. Previously, the behavior the same but with a default precision of 6.
1335 This more closely matches ``str()``, and reduces surprises when adding
1336 alignment flags to the empty presentation type. This also affects the new
1337 complex.__format__ in the same way.
1338

Georg Brandlba83f822010-03-14 09:50:54 +00001477- Issue #1180193: When importing a module from a .pyc (or .pyo) file with an
1478 existing .py counterpart, override the co_filename attributes of all code

1534
Georg Brandlba83f822010-03-14 09:50:54 +00001535- Issue #4233: Changed semantic of ``_fileio.FileIO``'s ``close()`` method on
1536 file objects with closefd=False. The file descriptor is still kept open but
1537 the file object behaves like a closed file. The ``FileIO`` object also got a
1538 new readonly attribute ``closefd``.

1557
Benjamin Peterson399b1fe2008-10-25 02:53:28 +00001558- Using ``nonlocal`` as a variable name will now raise a Py3k SyntaxWarning

Georg Brandlba83f822010-03-14 09:50:54 +00001561- On windows, ``os.chdir()`` given unicode was not working if
1562 GetCurrentDirectoryW returned a path longer than MAX_PATH. (But It's doubtful
1563 this code path is really executed because I cannot move to such directory on
1564 win2k)

Georg Brandlba83f822010-03-14 09:50:54 +00001566- Issue #4069: When ``set.remove(element)`` is used with a set element, the
1567 element is temporarily replaced with an equivalent frozenset. But the
1568 eventual KeyError would always report the empty ``frozenset()`` as the missing
1569 key. Now it correctly refers to the initial element.

Walter Dörwalded960ac2009-05-03 22:36:33 +00001589- Issue #5108: Handle %s like %S and %R in PyUnicode_FromFormatV(): Call
1590 PyUnicode_DecodeUTF8() once, remember the result and output it in a second
1591 step. This avoids problems with counting UTF-8 bytes that ignores the effect
1592 of using the replace error handler in PyUnicode_DecodeUTF8().
1593
Walter Dörwald726ba8e2009-05-06 14:32:35 +00001594- Issue #3739: The unicode-internal encoder now reports the number of characters

Georg Brandlba83f822010-03-14 09:50:54 +00001597- Issue #2422: When compiled with the ``--with-valgrind`` option, the pymalloc
1598 allocator will be automatically disabled when running under Valgrind. This
1599 gives improved memory leak detection when running under Valgrind, while taking
1600 advantage of pymalloc at other times.

Georg Brandlba83f822010-03-14 09:50:54 +00002132- Issue #5679: The methods unittest.TestCase.addCleanup and doCleanups were
2133 added. addCleanup allows you to add cleanup functions that will be called
Michael Foord07ef4872009-05-02 22:43:34 +00002134 unconditionally (after setUp if setUp fails, otherwise after tearDown). This
2135 allows for much simpler resource allocation and deallocation during tests.

Georg Brandlba83f822010-03-14 09:50:54 +00002149- Issue #5663: Better failure messages for unittest asserts. Default assertTrue
Michael Foord345b2fe2009-04-02 03:20:38 +00002150 and assertFalse messages are now useful. TestCase has a longMessage attribute.
2151 This defaults to False, but if set to True useful error messages are shown in
2152 addition to explicit messages passed to assert methods.

Georg Brandlba83f822010-03-14 09:50:54 +00002407 for *nix machines for negative handles and large int handles. Without this
2408 check it is possible to segfault the interpreter.

Georg Brandlba83f822010-03-14 09:50:54 +00002427 the timestamp in the gzip stream. The default value remains the current time.

Georg Brandlba83f822010-03-14 09:50:54 +00002823 leak-chasing test runs give sensible results. The previous method of reaping
2824 threads could return successfully while some Thread objects were still
2825 referenced. This also introduces a new private function: ``thread._count()``.

R. David Murray14dcd432009-10-14 13:58:07 +00002833- Issue #7058: Added save/restore for things like sys.argv and cwd to

Guilherme Polo7f146ab2009-06-21 17:22:50 +00002842- Issue #5450: Moved tests involving loading tk from Lib/test/test_tcl to
2843 Lib/lib-tk/test/test_tkinter/test_loadtk. With this, these tests demonstrate
Georg Brandlba83f822010-03-14 09:50:54 +00002844 the same behaviour as test_ttkguionly (and now also test_tk) which is to skip
2845 the tests if DISPLAY is defined but can't be used.

2851 import both normal and optimised versions of modules. test_heapq and
2852 test_warnings have been adjusted to use it, tests for other modules with both
2853 C and Python implementations in the stdlib can be adjusted to use it over
2854 time.

Georg Brandlba83f822010-03-14 09:50:54 +00002862- regrtest no longer treats ImportError as equivalent to SkipTest. Imports that
2863 should cause a test to be skipped are now done using import_module from test
2864 support, which does the conversion.

2966
Amaury Forgeot d'Arc05e34492008-09-10 22:04:45 +00002967- Issue #3743: In a few places, PY_FORMAT_SIZE_T was incorrectly used with
2968 PyString_FromFormat or PyErr_Format to display size_t values. The macro
2969 PY_FORMAT_SIZE_T is designed to select the correct format for the OS
2970 ``printf`` function, whereas PyString_FromFormat has an independent
2971 implementation and uses "%zd" on all platforms for size_t values.
2972 This makes a difference on win64, where ``printf`` needs "%Id" to display
2973 64bit values.

2979 object; previously an int would be returned for small values. the __long__
2980 method is allowed to return either an int or a long, but the behaviour of

Vinay Sajip35e3b032008-09-01 14:33:59 +00002992- Issue #2534: speed up isinstance() and issubclass() by 50-70%, so as to
Antoine Pitrou0668c622008-08-26 22:42:08 +00002993 match Python 2.5 speed despite the __instancecheck__ / __subclasscheck__
2994 mechanism. In the process, fix a bug where isinstance() and issubclass(),
2995 when given a tuple of classes as second argument, were looking up
2996 __instancecheck__ / __subclasscheck__ on the tuple rather than on each
2997 type object.

3115 wrapper for warnings.catch_warnings() that makes it easier to check
3116 that expected warning messages are being reported.

Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00003136What's New in Python 2.6 beta 3?
3137================================
3138
Barry Warsaw07a4a382008-08-21 01:15:08 +00003139*Release date: 20-Aug-2008*
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00003140
3141Core and Builtins
3142-----------------
3143
Guido van Rossumf8402962008-08-20 15:01:50 +00003144- Issue #1878: Remove Py_TPFLAGS_HAVE_VERSION_TAG from
3145 Py_TPFLAGS_DEFAULT when not building the core. This means 3rd party
3146 extensions do not automatically benefit from the class attribute
3147 cache; they will have to explicitly add Py_TPFLAGS_HAVE_VERSION_TAG
3148 to their tp_flags field if they care. This is a backwards
3149 compatibility feature; in 3.0, all types will use the cache by
3150 default.
3151
Benjamin Petersonf647dc12008-08-20 01:27:30 +00003152- Keyword arguments can now follow starred arguments. (``f(a, *args,
3153 keyword=23)`` is now valid syntax.)
3154
Thomas Heller0ad5ae02008-08-19 19:25:04 +00003155- ctypes function pointers that are COM methods have a boolean True
3156 value again.
3157
Martin v. Löwisf91d46a2008-08-12 14:49:50 +00003158- Issue #3139: Make buffer-interface thread-safe wrt. PyArg_ParseTuple,
3159 by denying s# to parse objects that have a releasebuffer procedure,
3160 and introducing s*.
3161
Georg Brandl1e13ea92008-08-11 09:07:59 +00003162- Issue #3537: Fix an assertion failure when an empty but presized dict
3163 object was stored in the freelist.
3164
Mark Dickinsonb6467572008-08-04 21:30:09 +00003165- Issue #1481296: Make long(float('nan')) and int(float('nan')) raise
3166 ValueError consistently across platforms.
3167
Amaury Forgeot d'Arc39fd6722008-07-31 21:28:03 +00003168- Issue #3479: On platforms where sizeof(int) is smaller than sizeof(long)
3169 (64bit Unix, for example), unichr() would truncate its argument and return
3170 u'\x00' for unichr(2**32). Now it properly raises an OverflowError.
3171
Neal Norwitze7d8be82008-07-31 17:17:14 +00003172- Apply security patches from Apple.
3173
Amaury Forgeot d'Arc246daed2008-07-31 00:42:16 +00003174- Issue #2542: Now that issubclass() may call arbitrary code, ensure that
3175 PyErr_ExceptionMatches returns 0 when an exception occurs there.
3176
Antoine Pitrou92f82162008-07-25 22:22:08 +00003177- Issue #1819: function calls with several named parameters are now on
3178 average 35% faster (as measured by pybench).
3179
Amaury Forgeot d'Arce4921fe2008-07-21 22:00:38 +00003180- Issue #2378: An unexpected UnboundLocalError or NameError could appear when
3181 the python debugger steps into a class statement: the free variables (local
3182 variables defined in an outer scope) would be deleted from the outer scope.
3183
Gregory P. Smith0470bab2008-07-22 04:46:32 +00003184- Issue #2620: Overflow checking when allocating or reallocating memory
3185 was not always being done properly in some python types and extension
3186 modules. PyMem_MALLOC, PyMem_REALLOC, PyMem_NEW and PyMem_RESIZE have
3187 all been updated to perform better checks and places in the code that
3188 would previously leak memory on the error path when such an allocation
3189 failed have been fixed.
3190
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00003191Library
3192-------
3193
Hirokazu Yamamoto838c79f2008-08-20 13:14:07 +00003194- Issue #3612: Added some missing basic types in ctypes.wintypes.
3195
Benjamin Petersone977ad42008-08-20 01:42:01 +00003196- The methods ``is_in_tuple()``, ``is_vararg()``, and ``is_keywordarg()`` of
3197 symtable.Symbol have been deprecated for removal in 3.0 and the next release.
3198
Amaury Forgeot d'Arc351ffb82008-08-18 19:23:47 +00003199- Issue #2234: distutils failed for some versions of the cygwin compiler. The
3200 version reported by these tools does not necessarily follow the python
3201 version numbering scheme, so the module is less strict when parsing it.
3202
Nick Coghlanf70385a2008-08-18 12:42:46 +00003203- Issue #2235: Added Py3k warnings for types which will become unhashable
3204 under the stricter __hash__ inheritance rules in 3.0. Several types
3205 which did not meet the rules for hash invariants and were already
3206 unhashable in 3.0 have now been explicitly flagged as unhashable in
3207 2.6 as well (collections.Mapping, collections.Set, unittest.TestSuite,
3208 xml.dom.minidom.NamedNodeMap, numbers.Number, UserList.UserList)
3209
Brett Cannon88f801d2008-08-18 00:46:22 +00003210- Update __all__ for cookielib, csv, os, urllib2, and weakref to include things
3211 imported into the module but exposed as part of the module's API.
3212
Brett Cannon7b96f072008-08-18 00:41:11 +00003213- Remove an unneeded import of abc.ABCMeta from 'inspect'.
3214
Brett Cannon46225e72008-08-18 00:36:52 +00003215- Remove unneeded imports of 'sys' and 'warnings' from 'io'.
3216
Brett Cannon25c9d6a2008-08-17 22:10:11 +00003217- Remove unneeded imports of 'warnings' from shelve, filecmp, and dummy_thread.
3218
Hirokazu Yamamoto41a81eb2008-08-17 13:10:46 +00003219- Issue #3575: Incremental decoder's decode function now takes bytearray
3220 by using 's*' instead of 't#'.
3221
Mark Dickinson3e4caeb2009-02-21 20:27:01 +00003222- Issue #2222: Fixed reference leak when occurred os.rename()
Hirokazu Yamamoto7f30a682008-08-17 09:46:56 +00003223 fails unicode conversion on 2nd parameter. (windows only)
3224
Facundo Batista94f243a2008-08-17 03:38:39 +00003225- Issue 2464. urllib2 now supports a malformation in the URL received
3226 in a redirect.
3227
Brett Cannonabe423e2008-08-16 21:47:07 +00003228- Silence the DeprecationWarning raised when importing mimetools in
Brett Cannon721b1452008-08-16 22:00:27 +00003229 BaseHTTPServer, cgi (and rfc822), httplib.
Brett Cannonabe423e2008-08-16 21:47:07 +00003230
Facundo Batistaeb90b782008-08-16 14:44:07 +00003231- Issue #2776: fixed small issue when handling an URL with double slash
3232 after a 302 response in the case of not going through a proxy.
3233
Antoine Pitroub90a8be2008-08-15 21:03:21 +00003234- Issue #2676: in the email package, content-type parsing was hanging on
3235 pathological input because of quadratic or exponential behaviour of a
3236 regular expression.
3237
Antoine Pitrou11ec65d2008-08-14 21:04:30 +00003238- Issue #3476: binary buffered reading through the new "io" library is now
3239 thread-safe.
3240
Brett Cannonbf3157b2008-08-14 05:00:03 +00003241- Silence the DeprecationWarning of rfc822 when it is imported by mimetools
3242 since mimetools itself is deprecated. Because modules are cached, all
3243 subsequent imports of rfc822 will not raise a visible DeprecationWarning.
3244
Antoine Pitrou9fcd4b32008-08-11 17:21:36 +00003245- Issue #3134: shutil referenced undefined WindowsError symbol.
3246
Robert Schuppenies14646332008-08-10 11:01:53 +00003247- Issue #1342811: Fix leak in Tkinter.Menu.delete. Commands associated to
3248 menu entries were not deleted.
3249
Brett Cannon83e81842008-08-09 23:30:55 +00003250- Copied the implementation of reduce() to _functools.reduce() to have a
3251 version that did not raise a DeprecationWarning under -3.
3252
Antoine Pitrou76b8bee2008-08-09 17:27:23 +00003253- Issue #3205: When iterating over a BZ2File fails allocating memory, raise
3254 a MemoryError rather than silently stop the iteration.
3255
Guido van Rossum59ce9012008-08-09 14:55:34 +00003256- Issue #3487: sre "bytecode" validator. Passing invalid "re-bytecode"
3257 to _sre.compile() will now be rejected. This should not affect anybody
3258 since the re.compile() function never generates invalid re-bytecode.
3259
Skip Montanaroa032bf42008-08-08 22:52:51 +00003260- Issue #3436: Make csv.DictReader's fieldnames attribute a property so that
3261 upon first access it can be automatically initialized from the csv file if
3262 it wasn't initialized during instantiation.
3263
Brett Cannon3aa2a492008-08-06 22:28:09 +00003264- Issue #2338: Create imp.reload() to help with transitioning to Python 3.0 as
3265 the reload() built-in has been removed.
3266
Brett Cannon7e30b672008-08-04 21:52:25 +00003267- Changed code in the following modules/packages to remove warnings raised
Brett Cannonc1b76e42008-08-09 23:06:16 +00003268 while running under the ``-3`` flag: aifc, asynchat, asyncore, bdb, bsddb,

3271 pstats, pydoc, re, rlcompleter, SimpleXMLRPCServer, shelve, socket,
3272 subprocess, sqlite3, tarfile, Tkinter, test.test_support, textwrap,
3273 threading, tokenize, traceback, urlparse, wsgiref, xml, xmlrpclib.
Brett Cannon7e30b672008-08-04 21:52:25 +00003274
Lars Gustäbel727bd0b2008-08-02 11:26:39 +00003275- Issue #3039: Fix tarfile.TarFileCompat.writestr() which always
3276 raised an AttributeError.
3277
Benjamin Peterson01a24322008-07-28 23:35:27 +00003278- Issue #2523: Fix quadratic behaviour when read()ing a binary file without
Antoine Pitroude781a42008-08-09 12:43:23 +00003279 asking for a specific length. This problem only affected files opened
3280 using the new "io" module, not the built-in open() function.
Benjamin Peterson01a24322008-07-28 23:35:27 +00003281
Mark Dickinsonfe84cce2008-07-27 06:39:07 +00003282- Issue #3449: Update decimal module to use most recent specification
3283 (v. 1.68) and tests (v. 2.58) from IBM.
3284
Skip Montanarof9ac43f2008-07-27 00:50:41 +00003285- Issue 3437: Bug fix in robotparser parsing of Allow: lines.
3286
Raymond Hettinger8c664e82008-07-25 18:43:33 +00003287- Issue 1592: Improve error reporting when operations are attempted
3288 on a closed shelf.

3293
3294- Issue #3303: Fix a crash in locale.strcoll() when calling it with
3295 invalid arguments.
3296
3297- Issue #3302: Fix several crashes when calling locale's gettext functions
3298 with None arguments.
3299
3300- Issue #3389: Allow resolving dotted names for handlers in logging
3301 configuration files.
3302
3303- Deprecate the sunaudio module for removal in Python 3.0.
3304
Antoine Pitrou5fdfa3e2008-07-25 19:42:26 +00003305- Issue #3394: zipfile.writestr sets external attributes when passed a
3306 file name rather than a ZipInfo instance, so files are extracted with
3307 mode 0600 rather than 000 under Unix.
3308
Gregory P. Smitha36f8fe2008-08-04 00:13:29 +00003309- Issue #1857: subprocess.Popen.poll gained an additional _deadstate keyword
3310 argument in python 2.5, this broke code that subclassed Popen to include its
3311 own poll method. Fixed my moving _deadstate to an _internal_poll method.

3320
Nick Coghlan6e8fef02008-08-18 13:14:22 +00003321- Issue #2235: the C API function PyObject_HashNotImplemented and its
3322 interaction with the tp_hash slot (added in 2.6b2) are now documented
3323
Nick Coghlan2a0c2b12008-08-04 12:47:17 +00003324- Issue #643841: The language reference now provides more detailed
3325 coverage of the lookup process for special methods. The disclaimers
3326 regarding lack of coverage of new-style classes have also been
3327 removed, since the coverage is now fairly reasonable.

Raymond Hettingere3ae6552008-06-20 04:18:15 +00003330What's New in Python 2.6 beta 2?
3331================================
3332
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00003333*Release date: 17-Jul-2008*
3334
Raymond Hettingere3ae6552008-06-20 04:18:15 +00003335Core and Builtins
3336-----------------
3337
Georg Brandl3e483f62008-07-16 22:57:41 +00003338- Issue #3156: Fix inconsistent behavior of the bytearray type: all
3339 its methods now allow for items objects that can be converted to
3340 an integer using operator.index().
3341
Mark Dickinson64b7e502008-07-16 09:40:03 +00003342- Issue #3360: Fix incorrect parsing of '020000000000.0', which
3343 produced a ValueError instead of giving the correct float.
3344
Eric Smitha5fa5a22008-07-16 00:11:49 +00003345- Issue #3083: Add alternate (#) formatting for bin, oct, hex output
3346 for str.format(). This adds the prefix 0b, 0o, or 0x, respectively.
3347
Mark Dickinson7103aa42008-07-15 19:08:33 +00003348- Issue #3008: the float type has a new instance method 'float.hex'
3349 and a new class method 'float.fromhex' to convert floating-point
3350 numbers to and from hexadecimal strings, respectively.
3351
Nick Coghlan6d6bd442008-07-15 15:40:22 +00003352- Issue #2235: __hash__ is once again inherited by default. To allow
3353 collections.Hashable to remain meaningful in the presence of the
3354 default hash implementation (object.__hash__), it is now possible
3355 to explicit block inheritance of hash by setting __hash__=None at
3356 the Python level, or tp_hash=PyObject_HashNotImplemented at the C
3357 level.
3358
Nick Coghlanb028f502008-07-13 14:52:36 +00003359- Issue #3221: Issue a RuntimeWarning instead of raising SystemError if
3360 the parent module cannot be found while performing an absolute import.
3361 This means that an incorrectly defined __package__ attribute will
3362 now only prevent relative imports in that module rather than causing
3363 all imports from that module to fail.
3364
Nick Coghlan14ff9942008-07-08 14:21:42 +00003365- Issue #2517: Allow unicode messages in Exceptions again by correctly
3366 bypassing the instance dictionary when looking up __unicode__ on
3367 new-style classes.
3368
Amaury Forgeot d'Arcbdd941f2008-07-01 20:38:04 +00003369- Issue #3242: Fix a crash inside the print statement, if sys.stdout is
3370 set to a custom object whose write() method happens to install
3371 another file in sys.stdout.
3372
Amaury Forgeot d'Arc1f40c8a2008-06-30 22:42:40 +00003373- Issue #3088: Corrected a race condition in classes derived from

3375 another thread's dictionary.
3376
Mark Dickinson1ec2fcd2008-06-20 14:53:43 +00003377- Issue #3004: Minor change to slice.indices(): the start and stop
3378 arguments are now treated identically, making the behaviour easier
3379 to describe and understand. For example, slice(None, -10,
3380 1).indices(9) now returns (0, 0, 1) instead of (0, -1, 1), and
3381 slice(None, 10, -1).indices(10) returns (9, 9, -1) instead of (9,
3382 10, -1).
3383
Georg Brandl278fc502008-07-19 12:46:12 +00003384- Issue #3219: Calling a function with repeated keyword arguments,
3385 f(a=2, a=23), would not cause a syntax error. This was a regression
3386 from 2.4 caused by the switch to the new compiler.

Georg Brandl5cc774e2008-06-11 20:28:06 +00003836 PPC64 and x86_64 support in one binary).
Ronald Oussoren5640ce22008-06-05 12:58:24 +00003837
3838 This is controlled by the configure argument ``--with-universal-archs``:
3839

3841
3842 - ``--with-universal-archs=32-bit``: install 2-way universal, 32-bit (the default)
3843
3844 - ``--with-universal-archs=64-bit``: install 2-way universal, 64-bit
3845

Georg Brandl3ee81df2008-05-17 18:14:43 +00003898- Issue #1631171: Re-implement the 'warnings' module in C (the
3899 original Python code has been kept as backup). This will allow for
3900 using the 'warning's machinery in such places as the parser where
3901 use of pure Python code is not possible. Both the ``showarning()``
3902 and ``formatwarning()`` gain an optional 'line' argument which is
3903 not called by default for backwards-compatibility reasons. Setting
3904 ``warnings.showwarning()`` to an implementation that lacks support
3905 for the ``line`` argument will raise a DeprecationWarning.

Georg Brandl3ee81df2008-05-17 18:14:43 +00003968- Issue #2550: The approach used by client/server code for obtaining
3969 ports to listen on in network-oriented tests has been refined in an
3970 effort to facilitate running multiple instances of the entire
3971 regression test suite in parallel without issue.
3972 test_support.bind_port() has been fixed such that it will always
3973 return a unique port -- which wasn't always the case with the
3974 previous implementation, especially if socket options had been set
3975 that affected address reuse (i.e. SO_REUSEADDR, SO_REUSEPORT). The
3976 new implementation of bind_port() will actually raise an exception
3977 if it is passed an AF_INET/SOCK_STREAM socket with either the
3978 SO_REUSEADDR or SO_REUSEPORT socket option set. Furthermore, if
3979 available, bind_port() will set the SO_EXCLUSIVEADDRUSE option on
3980 the socket it's been passed. This currently only applies to
3981 Windows. This option prevents any other sockets from binding to the
3982 host/port we've bound to, thus removing the possibility of the
3983 'non-deterministic' behaviour, as Microsoft puts it, that occurs
3984 when a second SOCK_STREAM socket binds and accepts to a host/port
3985 that's already been bound by another socket. The optional preferred
3986 port parameter to bind_port() has been removed. Under no
3987 circumstances should tests be hard coding ports!
3988
3989 test_support.find_unused_port() has also been introduced, which will
3990 pass a temporary socket object to bind_port() in order to obtain an
3991 unused port. The temporary socket object is then closed and
3992 deleted, and the port is returned. This method should only be used
3993 for obtaining an unused port in order to pass to an external program
3994 (i.e. the -accept [port] argument to openssl's s_server mode) or as
3995 a parameter to a server-oriented class that doesn't give you direct
3996 access to the underlying socket used.
3997
3998 Finally, test_support.HOST has been introduced, which should be used
3999 for the host argument of any relevant socket calls (i.e. bind and
4000 connect).
Trent Nelsone41b0062008-04-08 23:47:30 +00004001
4002 The following tests were updated to following the new conventions:
Georg Brandl3ee81df2008-05-17 18:14:43 +00004003 test_socket, test_smtplib, test_asyncore, test_ssl, test_httplib,
Trent Nelsone41b0062008-04-08 23:47:30 +00004004 test_poplib, test_ftplib, test_telnetlib, test_socketserver,
4005 test_asynchat and test_socket_ssl.
4006
Georg Brandl3ee81df2008-05-17 18:14:43 +00004007 It is now possible for multiple instances of the regression test
4008 suite to run in parallel without issue.

Thomas Heller78b8f442008-03-05 14:53:39 +00004212- The bundled libffi copy is now in sync with the recently released
4213 libffi3.0.4 version, apart from some small changes to
Georg Brandl3ee81df2008-05-17 18:14:43 +00004214 Modules/_ctypes/libffi/configure.ac. On OS X, preconfigured libffi
4215 files are used. On all linux systems the --with-system-ffi
4216 configure option defaults to "yes".

4275-----------------
4276
Fred Drakea8ee94b2008-03-01 02:45:07 +00004277- Issue #2051: pyc and pyo files are no longer created with permission
Barry Warsaw52973612008-03-01 02:23:38 +00004278 644. The mode is now inherited from the py file.
Christian Heimes40346852008-02-23 17:52:07 +00004279
Georg Brandlad61bc82008-02-23 15:11:18 +00004280- Issue #2067: file.__exit__() now calls subclasses' close() method.
4281
4282- Patch #1759: Backport of PEP 3129 class decorators.
Christian Heimes5224d282008-02-23 15:01:05 +00004283
Vinay Sajipb7edfc42008-04-02 21:10:23 +00004284- Issue #1881: An internal parser limit has been increased. Also see
Facundo Batistafc2d0102008-02-23 12:01:13 +00004285 issue 215555 for a discussion.
4286
Eric Smitha73fbe72008-02-23 03:09:44 +00004287- Added the future_builtins module, which contains hex() and oct().
4288 These are the PEP 3127 version of these functions, designed to be
4289 compatible with the hex() and oct() builtins from Python 3.0. They
4290 differ slightly in their output formats from the existing, unchanged
4291 Python 2.6 builtins. The expected usage of the future_builtins
4292 module is:
4293 from future_builtins import hex, oct
4294
Eric Smith7ef40bf2008-02-20 23:34:22 +00004295- Issue #1600: Modifed PyOS_ascii_formatd to use at most 2 digit
4296 exponents for exponents with absolute value < 100. Follows C99
4297 standard. This is a change on Windows, which would use 3 digits.
4298 Also, added 'n' to the formats that PyOS_ascii_formatd understands,
4299 so that any alterations it does to the resulting string will be
4300 available in stringlib/formatter.h (for float.__format__).
4301
Eric Smith5a3c1352008-02-19 13:21:56 +00004302- Implemented PEP 3101, Advanced String Formatting. This adds a new
4303 builtin format(); a format() method for str and unicode; a
4304 __format__() method to object, str, unicode, int, long, float, and
4305 datetime; the class string.Formatter; and the C API
4306 PyObject_Format().
4307
Georg Brandl3ee81df2008-05-17 18:14:43 +00004308- Fixed several potential crashes, all caused by specially crafted
4309 __del__ methods exploiting objects in temporarily inconsistent
4310 state.
Amaury Forgeot d'Arc632fad32008-02-16 20:55:24 +00004311
Vinay Sajipb7edfc42008-04-02 21:10:23 +00004312- Issue #2115: Important speedup in setting __slot__ attributes. Also
Georg Brandl3ee81df2008-05-17 18:14:43 +00004313 prevent a possible crash: an Abstract Base Class would try to access
4314 a slot on a registered virtual subclass.
Amaury Forgeot d'Arc60d6c7f2008-02-15 21:22:45 +00004315
Georg Brandl3ee81df2008-05-17 18:14:43 +00004316- Fixed repr() and str() of complex numbers with infinity or nan as
4317 real or imaginary part.
Christian Heimes2f0da532008-02-15 06:57:08 +00004318
Georg Brandl3ee81df2008-05-17 18:14:43 +00004319- Clear all free lists during a gc.collect() of the highest generation
4320 in order to allow pymalloc to free more arenas. Python may give back
4321 memory to the OS earlier.
Christian Heimes3b718a72008-02-14 12:47:33 +00004322
Georg Brandl3ee81df2008-05-17 18:14:43 +00004323- Issue #2045: Fix an infinite recursion triggered when printing a
4324 subclass of collections.defaultdict, if its default_factory is set
4325 to a bound method.
Amaury Forgeot d'Arcb01aa432008-02-08 00:56:02 +00004326
Christian Heimesf75dbef2008-02-08 00:11:31 +00004327- Fixed a minor memory leak in dictobject.c. The content of the free
4328 list was not freed on interpreter shutdown.
4329
Georg Brandl21e99f42010-03-07 15:23:59 +00004330- Limit free list of method and built-in function objects to 256
Georg Brandl3ee81df2008-05-17 18:14:43 +00004331 entries each.
Christian Heimes6075a822008-02-06 12:44:34 +00004332
Georg Brandl3ee81df2008-05-17 18:14:43 +00004333- Patch #1953: Added ``sys._compact_freelists()`` and the C API
4334 functions ``PyInt_CompactFreeList`` and ``PyFloat_CompactFreeList``
Christian Heimes422051a2008-02-04 18:00:12 +00004335 to compact the internal free lists of pre-allocted ints and floats.
4336
Georg Brandl3ee81df2008-05-17 18:14:43 +00004337- Issue #1983: Fixed return type of fork(), fork1() and forkpty()
4338 calls. Python expected the return type int but the fork familie
4339 returns pi_t.
Christian Heimes951cc0f2008-01-31 23:08:23 +00004340
Georg Brandl3ee81df2008-05-17 18:14:43 +00004341- Issue #1678380: Fix a bug that identifies 0j and -0j when they
4342 appear in the same code unit.
Mark Dickinson105be772008-01-31 22:17:37 +00004343
Georg Brandl3ee81df2008-05-17 18:14:43 +00004344- Issue #2025: Add tuple.count() and tuple.index() methods to comply
4345 with the collections.Sequence API.

Georg Brandl3ee81df2008-05-17 18:14:43 +00004350- Added ``PyType_ClearCache()`` and ``sys._clear_type_cache`` to clear
4351 the internal lookup cache for ref leak tests.
Christian Heimes908caac2008-01-27 23:34:59 +00004352
Georg Brandl3ee81df2008-05-17 18:14:43 +00004353- Patch #1473257: generator objects gain a gi_code attribute. This is
4354 the same object as the func_code attribute of the function that
4355 produced the generator.
Georg Brandl0cdf9a32008-01-26 14:14:20 +00004356
Georg Brandl3ee81df2008-05-17 18:14:43 +00004357- Issue #1920: "while 0" statements were completely removed by the
4358 compiler, even in the presence of an "else" clause, which is
4359 supposed to be run when the condition is false. Now the compiler
4360 correctly emits bytecode for the "else" suite.
Amaury Forgeot d'Arc31eaafe2008-01-24 22:59:25 +00004361
Guido van Rossumeead05f2008-01-24 18:21:02 +00004362- A few crashers fixed: weakref_in_del.py (issue #1377858);
4363 loosing_dict_ref.py (issue #1303614, test67.py);
4364 borrowed_ref_[34].py (not in tracker).
4365
Vinay Sajipd7cf32e2008-01-24 12:43:33 +00004366- Issue #1069410: The "can't load dll" message box on Windows is
Christian Heimesb2302ba2008-01-23 17:15:06 +00004367 suppressed while an extension is loaded by calling SetErrorMode in
4368 dynload_win.c. The error is still reported properly.
4369
Georg Brandl3ee81df2008-05-17 18:14:43 +00004370- Issue #1915: Python compiles with --enable-unicode=no again. However
Christian Heimes082c9b02008-01-23 14:20:50 +00004371 several extension methods and modules do not work without unicode
4372 support.
4373
Georg Brandl26543b12008-01-21 18:36:51 +00004374- Issue #1882: when compiling code from a string, encoding cookies in the
4375 second line of code were not always recognized correctly.
4376
Georg Brandl14404b62008-01-19 19:27:05 +00004377- Issue #1679: "0x" was taken as a valid integer literal.
4378
Georg Brandl6caad7d2008-01-26 14:19:22 +00004379- Issue #1865: ``bytes`` as an alias for ``str`` and b"" as an alias "" were
Christian Heimes288e89a2008-01-18 18:24:07 +00004380 added.
4381
Christian Heimesc94e2b52008-01-14 04:13:37 +00004382- sys.float_info / PyFloat_GetInfo: The floating point information
4383 object was converted from a dict to a specialized structseq object.
4384
Georg Brandl3ee81df2008-05-17 18:14:43 +00004385- Patch #1816: Added sys.flags structseq. It exposes the status of
4386 most command line arguments and PYTHON* environment variables.
Christian Heimesf31b69f2008-01-14 03:42:48 +00004387
Georg Brandl3ee81df2008-05-17 18:14:43 +00004388- Objects/structseq.c: Implemented new structseq representation. The
4389 patch makes structseqs (e.g. the return value of os.stat) more
4390 readable.
Christian Heimes9c201962008-01-14 03:33:52 +00004391
Georg Brandl3ee81df2008-05-17 18:14:43 +00004392- Patch #1700288: added a type attribute cache that caches method

Georg Brandl3ee81df2008-05-17 18:14:43 +00004404- Improve some exception messages when Windows fails to load an
4405 extension module. Now we get for example '%1 is not a valid Win32
4406 application' instead of 'error code 193'.

Georg Brandl3ee81df2008-05-17 18:14:43 +00004414 and INF. float("nan"), float("inf") and float("-inf") now work on
4415 every platform with IEEE 754 semantics.
Christian Heimes0a8143f2007-12-18 23:22:54 +00004416
Georg Brandl3ee81df2008-05-17 18:14:43 +00004417- Compiler now generates simpler and faster code for dictionary
4418 literals. The oparg for BUILD_MAP now indicates an estimated
4419 dictionary size. There is a new opcode, STORE_MAP, for adding
4420 entries to the dictionary.

Georg Brandl3ee81df2008-05-17 18:14:43 +00004449- Patch #1739468: Directories and zipfiles containing a __main__.py
4450 file can now be directly executed by passing their name to the
4451 interpreter. The directory/zipfile is automatically inserted as the
4452 first entry in sys.path.

Georg Brandl3ee81df2008-05-17 18:14:43 +00004454- Issue #1265: Fix a problem with sys.settrace, if the tracing
4455 function uses a generator expression when at the same time the
4456 executed code is closing a paused generator.
Amaury Forgeot d'Arc0d75f092007-11-13 21:54:28 +00004457
Raymond Hettinger1760c8a2007-11-08 02:52:43 +00004458- sets and frozensets now have an isdisjoint() method.

4461
Neal Norwitz44f326e2007-10-05 05:29:17 +00004462- Fix warnings found by the new version of the Coverity checker.
4463
Georg Brandl21e99f42010-03-07 15:23:59 +00004464- The enumerate() built-in function is no longer bounded to sequences
Georg Brandl3ee81df2008-05-17 18:14:43 +00004465 smaller than LONG_MAX. Formerly, it raised an OverflowError. Now,
4466 automatically shifts from ints to longs.
Raymond Hettinger8f669372007-10-03 21:18:11 +00004467
Georg Brandl3ee81df2008-05-17 18:14:43 +00004468- Issue #1686386: Tuple's tp_repr did not take into account the
4469 possibility of having a self-referential tuple, which is possible
4470 from C code. Nor did object's tp_str consider that a type's tp_str
4471 could do something that could lead to an inifinite recursion.
4472 Py_ReprEnter() and Py_EnterRecursiveCall(), respectively, fixed the
4473 issues.
Brett Cannon0b14f242007-09-30 19:45:10 +00004474
Georg Brandl3ee81df2008-05-17 18:14:43 +00004475- Issue #1164: It was possible to trigger deadlock when using the
4476 'print' statement to write to a file since the GIL was not released
4477 as needed. Now PyObject_Print() does the right thing along with
4478 various tp_print implementations of the built-in types and those in
4479 the collections module.
Brett Cannon01531592007-09-17 03:28:34 +00004480
Georg Brandl3ee81df2008-05-17 18:14:43 +00004481- Issue #1147: Exceptions were directly allowing string exceptions in
4482 their throw() method even though string exceptions no longer
4483 allowed.
Brett Cannon4c20bc42007-09-11 21:02:28 +00004484
Georg Brandl3ee81df2008-05-17 18:14:43 +00004485- Issue #1096: Prevent a segfault from getting the repr of a very
4486 deeply nested list by using the recursion counter.
Brett Cannona0c05512007-09-10 21:38:27 +00004487
Brett Cannon1e534b52007-09-07 04:18:30 +00004488- Issue #1202533: Fix infinite recursion calls triggered by calls to
Georg Brandl3ee81df2008-05-17 18:14:43 +00004489 PyObject_Call() never calling back out to Python code to trigger
4490 recursion depth updates/checks. Required the creation of a static
4491 RuntimeError instance in case normalizing an exception put the
4492 recursion check value past its limit. Fixes crashers
4493 infinite_rec_(1|2|4|5).py.
Brett Cannon1e534b52007-09-07 04:18:30 +00004494

Neal Norwitz0ac60192007-05-27 04:08:54 +00004508- Add new attribute names for function objects. All the func_* become
Georg Brandl3ee81df2008-05-17 18:14:43 +00004509 __*__ attributes. (Some already existed, e.g., __doc__ and
4510 __name__.)
Neal Norwitz0ac60192007-05-27 04:08:54 +00004511
Neal Norwitz8b2bfbc2007-05-23 06:35:32 +00004512- Add -3 option to the interpreter to warn about features that are
4513 deprecated and will be changed/removed in Python 3.0.
4514
Georg Brandl2134e752007-05-21 20:34:16 +00004515- Patch #1686487: you can now pass any mapping after '**' in function
4516 calls.
4517
Collin Winter62903052007-05-18 23:11:24 +00004518- except clauses may now be spelled either "except E, target:" or
Georg Brandl3ee81df2008-05-17 18:14:43 +00004519 "except E as target:". This is to provide forwards compatibility
4520 with Python 3.0.
Collin Winter62903052007-05-18 23:11:24 +00004521
Brett Cannon229cee22007-05-05 01:34:02 +00004522- Deprecate BaseException.message as per PEP 352.
4523
Georg Brandl3ee81df2008-05-17 18:14:43 +00004524- Issue #1303614: don't expose object's __dict__ when the dict is
Georg Brandl21e99f42010-03-07 15:23:59 +00004525 inherited from a built-in base.
Armin Rigo9790a272007-05-02 19:23:31 +00004526
Vinay Sajip8549ce32007-05-06 17:53:37 +00004527- When __slots__ are set to a unicode string, make it work the same as
Neal Norwitzcbd9ee62007-04-14 05:25:50 +00004528 setting a plain string, ie don't expand to single letter identifiers.
4529
Raymond Hettinger13936692007-04-11 18:40:58 +00004530- Request #1191699: Slices can now be pickled.
4531
Raymond Hettinger4db5fe92007-04-12 04:10:00 +00004532- Request #1193128: str.translate() now allows a None argument for
4533 translations that only remove characters without re-mapping the
4534 remaining characters.
4535
Georg Brandl5cb76c12007-03-21 09:00:39 +00004536- Patch #1682205: a TypeError while unpacking an iterable is no longer
4537 masked by a generic one with the message "unpack non-sequence".
4538
Neal Norwitzaa754b72007-03-21 06:39:48 +00004539- Remove unused file Python/fmod.c.
4540
Guido van Rossum143b5642007-03-23 04:58:42 +00004541- Bug #1683368: The object.__init__() and object.__new__() methods are
4542 now stricter in rejecting excess arguments. The only time when
4543 either allows excess arguments is when it is not overridden and the
4544 other one is. For backwards compatibility, when both are
4545 overridden, it is a deprecation warning (for now; maybe a Py3k
Guido van Rossum234b1ff2007-03-23 19:39:01 +00004546 warning later). Also, type.__init__() insists on the same signature
4547 as supported by type.__new__().
Guido van Rossum143b5642007-03-23 04:58:42 +00004548
Georg Brandl3ee81df2008-05-17 18:14:43 +00004549- Patch #1675423: PyComplex_AsCComplex() now tries to convert an
4550 object to complex using its __complex__() method before falling back
4551 to the __float__() method. Therefore, the functions in the cmath
4552 module now can operate on objects that define a __complex__()
4553 method.
Georg Brandl2b869942007-03-17 16:08:45 +00004554
Georg Brandl3ee81df2008-05-17 18:14:43 +00004555- Patch #1623563: allow __class__ assignment for classes with
4556 __slots__. The old and the new class are still required to have the
4557 same slot names.

4563 ``object.__reduce_ex__()`` is called with an object that is faking
4564 its type.
Žiga Seilnacht20f43d32007-03-15 11:44:55 +00004565
Georg Brandl3ee81df2008-05-17 18:14:43 +00004566- Patch #1680015: Don't modify __slots__ tuple if it contains an

4570
Georg Brandl7b9c5552007-03-12 14:30:05 +00004571- Bug #1678647: write a newline after printing an exception in any
4572 case, even when converting the value to a string failed.
4573
Georg Brandl871f1bc2007-03-12 13:17:36 +00004574- The dir() function has been extended to call the __dir__() method on
Georg Brandl3ee81df2008-05-17 18:14:43 +00004575 its argument, if it exists. If not, it will work like before. This
4576 allows customizing the output of dir() in the presence of a
4577 __getattr__().

Georg Brandl3ee81df2008-05-17 18:14:43 +00004585- Patch #1491866: change the complex() constructor to allow
4586 parthensized forms. This means complex(repr(x)) now works instead of
4587 raising a ValueError.
Collin Wintere38051d2007-03-09 20:33:07 +00004588
Georg Brandlaa2321b2007-03-07 00:40:28 +00004589- Patch #703779: unset __file__ in __main__ after running a file. This
Georg Brandl3ee81df2008-05-17 18:14:43 +00004590 makes the filenames the warning module prints much more sensible
4591 when a PYTHONSTARTUP file is used.
Georg Brandlaa2321b2007-03-07 00:40:28 +00004592

4594 exception if the -i command line option or PYTHONINSPECT environment
Georg Brandl3ee81df2008-05-17 18:14:43 +00004595 variable is given, but break into the interactive interpreter just
4596 like on other exceptions or normal program exit.

Georg Brandl0fca97a2007-03-05 22:28:08 +00004604- Patch #1674228: when assigning a slice (old-style), check for the
4605 sq_ass_slice instead of the sq_slice slot.
4606
Georg Brandl3ee81df2008-05-17 18:14:43 +00004607- When printing an unraisable error, don't print exceptions. before
4608 the name. This duplicates the behavior whening normally printing
4609 exceptions.

5237 -- the failure just occurred later, with a more cumbersome
5238 exception.

Georg Brandl3ee81df2008-05-17 18:14:43 +00005519- Issue #829951: In the smtplib module, SMTP.starttls() now complies
5520 with RFC 3207 and forgets any knowledge obtained from the server not
5521 obtained from the TLS negotiation itself. Patch contributed by Bill
5522 Fenner.
Gregory P. Smith2b3ba582008-01-17 08:03:17 +00005523
Georg Brandl3ee81df2008-05-17 18:14:43 +00005524- Issue #1339: The smtplib.SMTP class has been refactored a bit such
Gregory P. Smithbde4ae42008-01-17 08:35:49 +00005525 that the SMTP.starttls() caller no longer needs to call ehlo()
5526 beforehand. SMTP.starttls() now raises an exception of the server
Georg Brandl3ee81df2008-05-17 18:14:43 +00005527 does not claim to support starttls. Adds the
5528 SMTP.ehlo_or_helo_if_needed() method. Patch contributed by Bill

5609 complex, tuple, list, dict, set, and frozenset. Formerly, it would
5610 silently miscode subclasses of those types. Now, it raises a
5611 ValueError instead.
Raymond Hettinger12e94202007-11-07 01:13:09 +00005612

Georg Brandl3ee81df2008-05-17 18:14:43 +00005627 time so that opening a database previously created with the DB_DUP
5628 or DB_DUPSORT flag set will keep the proper behavior on subsequent
5629 opens. Specifically: dictionary assignment to a DB object will
5630 replace all values for a given key when the database allows
5631 duplicate values. DB users should use DB.put(k, v) when they want
5632 to store duplicates; not DB[k] = v.
Gregory P. Smithec10a4a2007-11-05 02:32:26 +00005633

5639 characters with ASCII value less than 32. Also, it correctly quotes
5640 dots only if they occur on a single line, as opposed to the previous
5641 behavior of quoting dots if they are the second character of any
5642 line.
Georg Brandl4aef7272007-03-13 22:49:43 +00005643

5965-----
5966
Georg Brandl3ee81df2008-05-17 18:14:43 +00005967- Unified naming convention for free lists and their limits. All free
5968 lists in Object/ are named ``free_list``, the counter ``numfree``

5970 #ifndef block.
Christian Heimes5b970ad2008-02-06 13:33:44 +00005971
Georg Brandl3ee81df2008-05-17 18:14:43 +00005972- ``PySet_Add()`` can now modify a newly created frozenset. Similarly
5973 to ``PyTuple_SetItem``, it can be used to populate a brand new

5986
Georg Brandl3ee81df2008-05-17 18:14:43 +00005987- Issue #1521: On 64bit platforms, using PyArgs_ParseTuple with the t#
5988 of w# format code incorrectly truncated the length to an int, even
5989 when PY_SSIZE_T_CLEAN is set. The str.decode method used to return
5990 incorrect results with huge strings.
Georg Brandl6caad7d2008-01-26 14:19:22 +00005991
Georg Brandl3ee81df2008-05-17 18:14:43 +00005992- Issue #1629: Renamed Py_Size, Py_Type and Py_Refcnt to Py_SIZE,

6010- Fix some leftovers from the conversion from int to Py_ssize_t
6011 (relevant to strings and sequences of more than 2**31 items).
6012
6013- Make _PyGILState_NoteThreadState() static, it was not used anywhere
6014 outside of pystate.c and should not be necessary.
6015
Georg Brandl3ee81df2008-05-17 18:14:43 +00006016- ``PyImport_Import`` and ``PyImport_ImportModule`` now always do
6017 absolute imports. In earlier versions they might have used relative
6018 imports under some conditions.
Christian Heimes000a0742008-01-03 22:16:32 +00006019
Georg Brandl3ee81df2008-05-17 18:14:43 +00006020- Added case insensitive comparison methods ``PyOS_stricmp(char*,
6021 char*)`` and ``PyOS_strnicmp(char*, char*, Py_ssize_t)``.
Christian Heimes000a0742008-01-03 22:16:32 +00006022
Georg Brandl3ee81df2008-05-17 18:14:43 +00006023- Bug #1542693: remove semi-colon at end of PyImport_ImportModuleEx

Georg Brandl3ee81df2008-05-17 18:14:43 +00006048- Removed the macfs module. It had been deprecated since Python 2.5.
6049 This lead to the deprecation of macostools.touched() as it relied
6050 solely on macfs and was a no-op under OS X.
