41
Mark Hammond323b5da2011-10-17 11:05:36 +110042- Issue #7833: Extension modules built using distutils on Windows will no
43 longer include a "manifest" to prevent them failing at import time in some
44 embedded situations.
45
Benjamin Petersona7b09762011-10-15 13:43:21 -040046- Issue #13186: Fix __delitem__ on old-style instances when invoked through

Mark Dickinsondbbed042011-09-19 16:38:08 +010055- Issue #12973: Fix overflow checks that invoked undefined behaviour in
56 int.__pow__. These overflow checks were causing int.__pow__ to produce
57 incorrect results with recent versions of Clang, as a result of the
Mark Dickinsona96b0d12011-09-24 09:01:16 +010058 compiler optimizing the check away. Also fix similar overflow checks
59 in list_repeat (listobject.c) and islice_next (itertoolsmodule.c). These
60 bugs caused test failures with recent versions of Clang.
Mark Dickinsondbbed042011-09-19 16:38:08 +010061
Ezio Melotti15d6b652011-08-15 09:22:24 +030062- Issue #12266: Fix str.capitalize() to correctly uppercase/lowercase

67
Barry Warsawc5643282011-07-19 17:06:30 -040068- Issue #11627: Fix segfault when __new__ on a exception returns a

Antoine Pitrou16166452011-07-12 22:04:20 +020071- Issue #12149: Update the method cache after a type's dictionnary gets
72 cleared by the garbage collector. This fixes a segfault when an instance
73 and its type get caught in a reference cycle, and the instance's
74 deallocator calls one of the methods on the type (e.g. when subclassing
75 IOBase). Diagnosis and patch by Davide Rizzo.
76

82
Victor Stinnerd3c7e172011-05-30 23:49:13 +020083- Issue #1195: my_fgets() now always clears errors before calling fgets(). Fix
Victor Stinner08563d92011-05-30 23:44:13 +020084 the following case: sys.stdin.read() stopped with CTRL+d (end of file),
85 raw_input() interrupted by CTRL+c.
86
Łukasz Langa7a153902011-10-18 17:16:00 +020087- Issue #10860: httplib now correctly handles an empty port after port
88 delimiter in URLs.
89
Barry Warsawc5643282011-07-19 17:06:30 -040090- dict_proxy objects now display their contents rather than just the class
91 name.

Florent Xiclunac2279652012-02-12 14:49:03 +0100120- Issue #13994: Earlier partial revert of Distutils enhancements in 2.7
Ned Deilyc47a4592012-02-11 20:40:24 +0100121 has left two versions of customize_compiler, the original in
122 distutils.sysconfig and another copy in distutils.ccompiler, with some
123 parts of distutils calling one and others using the other.
124 Complete the revert back to only having one in distutils.sysconfig as
125 is the case in 3.x.
126
Ned Deily0d0ea482012-02-10 12:59:06 +0100127- Issue #13590: On OS X 10.7 and 10.6 with Xcode 4.2, building
128 Distutils-based packages with C extension modules may fail because
129 Apple has removed gcc-4.2, the version used to build python.org
130 64-bit/32-bit Pythons. If the user does not explicitly override
131 the default C compiler by setting the CC environment variable,
132 Distutils will now attempt to compile extension modules with clang
133 if gcc-4.2 is required but not found. Also as a convenience, if
134 the user does explicitly set CC, substitute its value as the default
135 compiler in the Distutils LDSHARED configuration variable for OS X.
136 (Note, the python.org 32-bit-only Pythons use gcc-4.0 and the 10.4u
137 SDK, neither of which are available in Xcode 4. This change does not
138 attempt to override settings to support their use with Xcode 4.)
139
Senthil Kumaran59e7c8f2012-02-09 18:22:01 +0800140- Issue #9021: Add an introduction to the copy module documentation.
141
Senthil Kumaran607e31e2012-02-09 17:43:31 +0800142- Issue #6005: Examples in the socket library documentation use sendall, where
143 relevant, instead send method.
144
Petri Lehtinenc7fd5232011-05-09 12:24:09 +0200145- Issue #10811: Fix recursive usage of cursors. Instead of crashing,
146 raise a ProgrammingError now.
147
Ned Deily2c8bf042012-02-06 00:55:50 +0100148- Issue #10881: Fix test_site failures with OS X framework builds.

226 Patch by sbt.
227

Ned Deily87e82bb2011-06-28 19:52:59 -0700413- Issue #9516: On Mac OS X, change Distutils to no longer globally attempt to
414 check or set the MACOSX_DEPLOYMENT_TARGET environment variable for the
415 interpreter process. This could cause failures in non-Distutils subprocesses
416 and was unreliable since tests or user programs could modify the interpreter
417 environment after Distutils set it. Instead, have Distutils set the the
418 deployment target only in the environment of each build subprocess. It is
419 still possible to globally override the default by setting
420 MACOSX_DEPLOYMENT_TARGET before launching the interpreter; its value must be
421 greater or equal to the default value, the value with which the interpreter
422 was built.

451 updating the check interval, so if the user decreases the check interval,
452 the ticker doesn't have to wind down to zero from the old starting point
453 before the new interval takes effect. And if the user increases the
454 interval, it makes sure the new limit takes effect right away rather have an
455 early task switch before recognizing the new interval.

1388
Raymond Hettinger20397532010-09-12 02:11:45 +00001389- Issue #9825: removed __del__ from the definition of collections.OrderedDict.
1390 This prevents user-created self-referencing ordered dictionaries from
1391 becoming permanently uncollectable GC garbage. The downside is that
1392 removing __del__ means that the internal doubly-linked list has to wait for
1393 GC collection rather than freeing memory immediately when the refcnt drops
1394 to zero.
1395

1399
Antoine Pitrouc818ed42010-09-07 21:40:25 +00001400- Issue #9792: In case of connection failure, socket.create_connection()

1402 to fetch the original errno, or to filter timeout errors. Now the
1403 original error is re-raised.

Ezio Melottiab2eb0e2010-06-05 19:21:32 +00001853- Issue #8271: during the decoding of an invalid UTF-8 byte sequence, only the
1854 start byte and the continuation byte(s) are now considered invalid, instead
1855 of the number of bytes specified by the start byte.
1856 E.g.: '\xf1\x80AB'.decode('utf-8', 'replace') now returns u'\ufffdAB' and
1857 replaces with U+FFFD only the start byte ('\xf1') and the continuation byte

1869 (2**53+1 == complex(2**53) == 2**53), breaking transivity of equality.

Georg Brandlfee0f442010-05-22 21:26:21 +00002065- Issue #8567: Fix precedence of signals in Decimal module: when a Decimal
2066 operation raises multiple signals and more than one of those signals is
2067 trapped, the specification determines the order in which the signals should be
2068 handled. In many cases this order wasn't being followed, leading to the wrong
2069 Python exception being raised.

2119 indefinitely if the other end didn't respond.
2120
Georg Brandlfee0f442010-05-22 21:26:21 +00002121- The do_handshake() method of SSL objects now adjusts the blocking mode of the
2122 SSL structure if necessary (as other methods already do).

Philip Jenveyaebbaeb2010-04-06 23:24:45 +00002239- Issue #7301: Add environment variable $PYTHONWARNINGS.
2240
Benjamin Peterson3a1dfa22010-04-06 21:50:00 +00002241- Issue #8329: Don't return the same lists from select.select when no fds are
2242 changed.
2243
Georg Brandlfee0f442010-05-22 21:26:21 +00002244- Issue #8259: ``1L << (2**31)`` no longer produces an 'outrageous shift error'
Mark Dickinson82791672010-04-06 16:47:55 +00002245 on 64-bit machines. The shift count for either left or right shift is
2246 permitted to be up to sys.maxsize.

Georg Brandlfee0f442010-05-22 21:26:21 +00002254- Issue #7994: Issue a PendingDeprecationWarning if object.__format__ is called
2255 with a non-empty format string. This is an effort to future-proof user
2256 code. If a derived class does not currently implement __format__ but later
2257 adds its own __format__, it would most likely break user code that had
Antoine Pitrou01a196a2011-01-02 20:05:11 +00002258 supplied a format string. This will be changed to a DeprecationWarning in
Georg Brandlfee0f442010-05-22 21:26:21 +00002259 Python 3.3 and it will be an error in Python 3.4.

Georg Brandlfee0f442010-05-22 21:26:21 +00002309- Issue #7279: Comparisons involving a Decimal signaling NaN now signal
2310 InvalidOperation instead of returning False. (Comparisons involving a quiet
2311 NaN are unchanged.) Also, Decimal quiet NaNs are now hashable; Decimal
2312 signaling NaNs remain unhashable.

Georg Brandlfee0f442010-05-22 21:26:21 +00002314- Issue #2531: Comparison operations between floats and Decimal instances now
2315 return a result based on the numeric values of the operands; previously they
2316 returned an arbitrary result based on the relative ordering of id(float) and
2317 id(Decimal).

Georg Brandlfee0f442010-05-22 21:26:21 +00002320 argument `-` which tells it to read files to compile from stdin. Each line is
2321 read on demand and the named file is compiled immediately. (Original patch by
2322 Piotr Ożarowski).

Georg Brandlfee0f442010-05-22 21:26:21 +00002331- Comparisons using one of <, <=, >, >= between a complex instance and a
2332 Fractions instance now raise TypeError instead of returning True/False. This
2333 makes Fraction <=> complex comparisons consistent with int <=> complex, float
2334 <=> complex, and complex <=> complex comparisons.

Antoine Pitrouf3fa0742010-01-31 22:26:04 +00002751- Issue #6939: Fix file I/O objects in the `io` module to keep the original
Georg Brandlba83f822010-03-14 09:50:54 +00002752 file position when calling `truncate()`. It would previously change the file
2753 position to the given argument, which goes against the tradition of
Antoine Pitrouf3fa0742010-01-31 22:26:04 +00002754 ftruncate() and other truncation APIs. Patch by Pascal Chambon.

Georg Brandlba83f822010-03-14 09:50:54 +00002756- Issue #7610: Reworked implementation of the internal ``zipfile.ZipExtFile``
2757 class used to represent files stored inside an archive. The new
2758 implementation is significantly faster and can be wrapped in a
2759 ``io.BufferedReader`` object for more speedups. It also solves an issue
2760 where interleaved calls to ``read()`` and ``readline()`` give wrong results.

2773 encoded string for them. This ensures that the upload and register commands

2850
Georg Brandlba83f822010-03-14 09:50:54 +00002851- The ``__complex__()`` method is now looked up on the class of instances to
2852 make it consistent with other special methods.

Antoine Pitrou5b7139a2010-01-02 21:12:58 +00002854- Issue #7462: Implement the stringlib fast search algorithm for the `rfind`,

2856
Mark Dickinson1b34d252010-01-01 17:27:30 +00002857- Issue #5080: A number of functions and methods previously produced a
Georg Brandlba83f822010-03-14 09:50:54 +00002858 DeprecationWarning when passed a float argument where an integer was expected.
2859 These functions and methods now raise TypeError instead. The majority of the
2860 effects of this change are in the extension modules, but some core functions
2861 and methods are affected: notably the 'chr', 'range' and 'xrange' builtins,
2862 and many unicode/str methods.

2876 of integers: the result of a/b is now correctly rounded for ints a and b (at
2877 least on IEEE 754 platforms), and in particular does not depend on the
2878 internal representation of a long.

2886
Georg Brandlba83f822010-03-14 09:50:54 +00002887 These executables now work properly with the arch(1) command: ``arch -ppc
2888 python`` will start a universal binary version of python in PPC mode (unlike

2979 TypeError. For the 'L' format code (which previously had no warning) there is
2980 now a DeprecationWarning.

3028 upper case. This only affects 'inf' and 'nan', since 'f' no longer converts
3029 to 'g' for large values.
Amaury Forgeot d'Arcd7288712009-12-01 21:51:04 +00003030
Georg Brandlba83f822010-03-14 09:50:54 +00003031- Remove switch from "%f" formatting to "%g" formatting for floats larger than
3032 1e50 in absolute value.
Mark Dickinson9dd5e162009-11-23 20:54:09 +00003033
Georg Brandlba83f822010-03-14 09:50:54 +00003034- Remove restrictions on precision when formatting floats. E.g., "%.120g" %
3035 1e-100 used to raise OverflowError, but now gives the requested 120
3036 significant digits instead.

Ronald Oussoren315cd0c2009-11-19 16:25:21 +00003044
Georg Brandlba83f822010-03-14 09:50:54 +00003045- Issue #7117: ``repr(x)`` for a float x returns a result based on the shortest
3046 decimal string that's guaranteed to round back to x under correct rounding
3047 (with round-half-to-even rounding mode). Previously it gave a string based on
3048 rounding x to 17 decimal digits. repr(x) for a complex number behaves
3049 similarly. On platforms where the correctly-rounded strtod and dtoa code is
3050 not supported (see below), repr is unchanged.
Mark Dickinsonb678de82009-11-19 18:41:49 +00003051
Georg Brandlba83f822010-03-14 09:50:54 +00003052- Issue #7117: On almost all platforms: float-to-string and string-to-float
3053 conversions within Python are now correctly rounded. Places these conversions
3054 occur include: str for floats and complex numbers; the float and complex
3055 constructors; old-style and new-style numeric formatting; serialization and
3056 deserialization of floats and complex numbers using marshal, pickle and json;
3057 parsing of float and imaginary literals in Python code; Decimal-to-float
3058 conversion.
Mark Dickinsonb678de82009-11-19 18:41:49 +00003059
Georg Brandlba83f822010-03-14 09:50:54 +00003060 The conversions use a Python-adapted version of David Gay's well-known dtoa.c,
3061 providing correctly-rounded strtod and dtoa C functions. This code is
3062 supported on Windows, and on Unix-like platforms using gcc, icc or suncc as
3063 the C compiler. There may be a small number of platforms on which correct
3064 operation of this code cannot be guaranteed, so the code is not used: notably,
3065 this applies to platforms where the C double format is not IEEE 754 binary64,
3066 and to platforms on x86 hardware where the x87 FPU is set to 64-bit precision
3067 and Python's configure script is unable to determine how to change the FPU
3068 precision. On these platforms conversions use the platform strtod and dtoa,
3069 as before.
Mark Dickinsonb678de82009-11-19 18:41:49 +00003070
Georg Brandlba83f822010-03-14 09:50:54 +00003071- Issue #7117: Backport round implementation from Python 3.x. ``round()`` now
3072 uses the correctly-rounded string <-> float conversions described above (when
3073 available), and so produces correctly rounded results that will display nicely
3074 under the float repr. There are two related small changes: (1) round now
3075 accepts any class with an ``__index__()`` method for its second argument (but
3076 no longer accepts floats for the second argument), and (2) an excessively
3077 large second integer argument (e.g., ``round(1.234, 10**100)``) no longer
3078 raises an exception.

Mark Dickinsonb1d45852009-05-11 15:33:08 +00003219- Issue #5981: Fix three minor inf/nan issues in float.fromhex:
Mark Dickinsonb1d45852009-05-11 15:33:08 +00003220
Georg Brandlba83f822010-03-14 09:50:54 +00003221 (1) inf and nan strings with trailing whitespace were incorrectly rejected;
3222 (2) parsing of strings representing infinities and nans was locale aware; and
3223 (3) the interpretation of fromhex('-nan') didn't match that of float('-nan').

Georg Brandlba83f822010-03-14 09:50:54 +00003225- Issue #5920: For ``float.__format__()``, change the behavior with the empty
3226 presentation type (that is, not one of 'e', 'f', 'g', or 'n') to be like 'g'
3227 but with at least one decimal point and with a default precision
3228 of 12. Previously, the behavior the same but with a default precision of 6.
3229 This more closely matches ``str()``, and reduces surprises when adding
3230 alignment flags to the empty presentation type. This also affects the new
3231 complex.__format__ in the same way.
3232
3233- Issue #5890: In subclasses of 'property' the __doc__ attribute was shadowed by
3234 classtype's, even if it was None. property now inserts the __doc__ into the

3457 this code path is really executed because I cannot move to such directory on

3462 eventual KeyError would always report the empty ``frozenset()`` as the missing

3484 PyUnicode_DecodeUTF8() once, remember the result and output it in a second
3485 step. This avoids problems with counting UTF-8 bytes that ignores the effect
3486 of using the replace error handler in PyUnicode_DecodeUTF8().

Walter Dörwald726ba8e2009-05-06 14:32:35 +00003488- Issue #3739: The unicode-internal encoder now reports the number of characters

Georg Brandlba83f822010-03-14 09:50:54 +00003491- Issue #2422: When compiled with the ``--with-valgrind`` option, the pymalloc

3493 gives improved memory leak detection when running under Valgrind, while taking
3494 advantage of pymalloc at other times.

4659 struct.error. Previously an x with an __int__ method could be packed by
4660 'b', 'B', 'h', 'H', 'i', 'l', '*b', '*h' ,'*i', '*l', and an x with a
4661 __long__ method could be packed by 'q', 'Q', '*q', '*Q'; for x with
4662 neither __int__ nor __long__, TypeError used to be raised (with a
4663 confusing error message) for 'I', 'L', '*B', '*H', '*I', '*L', and
4664 struct.error in other cases.

Georg Brandlba83f822010-03-14 09:50:54 +00004717 leak-chasing test runs give sensible results. The previous method of reaping
4718 threads could return successfully while some Thread objects were still
4719 referenced. This also introduces a new private function: ``thread._count()``.
Antoine Pitrou59c44f32009-10-30 17:07:08 +00004720
Georg Brandlba83f822010-03-14 09:50:54 +00004721- Issue #7151: Fixed regrtest -j so that output to stderr from a test no longer

Georg Brandl2bd92a52009-10-11 21:10:07 +00004839- Issue #3850: recursion tests in Tools/scripts/find_recursion_limit.py can raise
Antoine Pitrou3c9f5412008-09-13 20:30:30 +00004840 AttributeError instead of RuntimeError, depending in which C API call
4841 exactly the recursion limit is exceeded. Consequently, both exception types
4842 are caught and silenced.

4858
Martin v. Löwis9fa5a282008-09-11 06:53:30 +00004859- Issue #3642: Suppress warning in obmalloc when size_t is larger than uint.
4860
Amaury Forgeot d'Arc05e34492008-09-10 22:04:45 +00004861- Issue #3743: In a few places, PY_FORMAT_SIZE_T was incorrectly used with
4862 PyString_FromFormat or PyErr_Format to display size_t values. The macro
4863 PY_FORMAT_SIZE_T is designed to select the correct format for the OS
4864 ``printf`` function, whereas PyString_FromFormat has an independent
4865 implementation and uses "%zd" on all platforms for size_t values.
4866 This makes a difference on win64, where ``printf`` needs "%Id" to display
4867 64bit values.
4868
Benjamin Peterson97179b02008-09-09 20:55:01 +00004869- Issue #3634: _weakref.ref(Exception).__init__() gave invalid return value on
4870 error.
4871
Amaury Forgeot d'Arcd3ffb892008-09-09 07:24:30 +00004872- Issue #3777: long() applied to a float object now always return a long
4873 object; previously an int would be returned for small values. the __long__
4874 method is allowed to return either an int or a long, but the behaviour of
4875 float objects should not change to respect backward compatibility.
4876
Amaury Forgeot d'Arc3571fbf2008-09-01 19:52:00 +00004877- Issue #3751: str.rpartition would perform a left-partition when called with
4878 a unicode argument.
4879
Benjamin Peterson17f03ca2008-09-01 14:18:30 +00004880- Issue #3683: Fix compilation when --without-threads is given.
4881
Antoine Pitroud4ae97b2008-08-29 18:39:48 +00004882- Issue #3668: Fix a memory leak with the "s*" argument parser in
Vinay Sajip35e3b032008-09-01 14:33:59 +00004883 PyArg_ParseTuple and friends, which occurred when the argument for "s*"
Antoine Pitroud4ae97b2008-08-29 18:39:48 +00004884 was correctly parsed but parsing of subsequent arguments failed.
4885
Vinay Sajip35e3b032008-09-01 14:33:59 +00004886- Issue #2534: speed up isinstance() and issubclass() by 50-70%, so as to
Antoine Pitrou0668c622008-08-26 22:42:08 +00004887 match Python 2.5 speed despite the __instancecheck__ / __subclasscheck__
4888 mechanism. In the process, fix a bug where isinstance() and issubclass(),
4889 when given a tuple of classes as second argument, were looking up
4890 __instancecheck__ / __subclasscheck__ on the tuple rather than on each
4891 type object.
4892
Neal Norwitz18aa3882008-08-24 05:04:52 +00004893- Fix crashes on memory allocation failure found with failmalloc.
4894
4895- Fix memory leaks found with valgrind and update suppressions file.
4896
4897- Fix compiler warnings in opt mode which would lead to invalid memory reads.
4898
4899- Fix problem using wrong name in decimal module reported by pychecker.
4900
Christian Heimes7d4c3172008-08-22 19:47:25 +00004901- Silenced another compiler warning about a used but not defined
4902 function 'stringlib_contains_obj'.

4905 ``__delslice__``.
4906
Gregory P. Smith2bb25cc2008-09-02 05:29:51 +00004907- Issue #3678: Correctly pass LDFLAGS and LDLAST to the linker on shared
4908 library targets in the Makefile.
4909
Gregory P. Smith980b99b2008-09-07 05:15:18 +00004910- Issue #1204: The configure script now tests for additional libraries
4911 that may be required when linking against readline. This fixes issues
4912 with x86_64 builds on some platforms (a few Linux flavors and OpenBSD).

Nick Coghland2e09382008-09-11 12:11:06 +00004935- Issue #3781: Clean up the API for warnings.catch_warnings() by having it
Brett Cannon672237d2008-09-09 00:49:16 +00004936 return a list or None rather than a custom object.
4937
Benjamin Peterson6ac7d7c2008-09-06 19:28:11 +00004938- Issue #1638033: Cookie.Morsel gained the httponly attribute.
4939
Antoine Pitrouebcd0ce2008-09-05 23:30:23 +00004940- Issue #3535: zipfile couldn't read some zip files larger than 2GB.

Brett Cannon1eaf0742008-09-02 01:25:16 +00004962 warnings.catch_warnings() along with some API cleanup. Expanding the tests
4963 for catch_warnings() also led to an improvement in the raising of a
4964 DeprecationWarning related to warnings.warn_explicit().
4965
Benjamin Peterson973e6c22008-09-01 23:12:58 +00004966- The deprecation warnings for the old camelCase threading API were removed.

Amaury Forgeot d'Arc293924b2008-09-02 23:19:56 +00004989- Issue #2975: When compiling several extension modules with Visual Studio 2008
4990 from the same python interpreter, some environment variables would grow
4991 without limit.
4992
Benjamin Peterson37346b22008-08-23 20:27:43 +00004993- Issue #3643: Added a few more checks to _testcapi to prevent segfaults by

5036-----------------
5037
Guido van Rossumf8402962008-08-20 15:01:50 +00005038- Issue #1878: Remove Py_TPFLAGS_HAVE_VERSION_TAG from
5039 Py_TPFLAGS_DEFAULT when not building the core. This means 3rd party
5040 extensions do not automatically benefit from the class attribute
5041 cache; they will have to explicitly add Py_TPFLAGS_HAVE_VERSION_TAG
5042 to their tp_flags field if they care. This is a backwards
5043 compatibility feature; in 3.0, all types will use the cache by
5044 default.
5045
Benjamin Petersonf647dc12008-08-20 01:27:30 +00005046- Keyword arguments can now follow starred arguments. (``f(a, *args,
5047 keyword=23)`` is now valid syntax.)
5048
Thomas Heller0ad5ae02008-08-19 19:25:04 +00005049- ctypes function pointers that are COM methods have a boolean True
5050 value again.
5051
Martin v. Löwisf91d46a2008-08-12 14:49:50 +00005052- Issue #3139: Make buffer-interface thread-safe wrt. PyArg_ParseTuple,
5053 by denying s# to parse objects that have a releasebuffer procedure,
5054 and introducing s*.
5055
Georg Brandl1e13ea92008-08-11 09:07:59 +00005056- Issue #3537: Fix an assertion failure when an empty but presized dict
5057 object was stored in the freelist.
5058
Mark Dickinsonb6467572008-08-04 21:30:09 +00005059- Issue #1481296: Make long(float('nan')) and int(float('nan')) raise
5060 ValueError consistently across platforms.
5061
Amaury Forgeot d'Arc39fd6722008-07-31 21:28:03 +00005062- Issue #3479: On platforms where sizeof(int) is smaller than sizeof(long)
5063 (64bit Unix, for example), unichr() would truncate its argument and return
5064 u'\x00' for unichr(2**32). Now it properly raises an OverflowError.
5065
Neal Norwitze7d8be82008-07-31 17:17:14 +00005066- Apply security patches from Apple.
5067
Amaury Forgeot d'Arc246daed2008-07-31 00:42:16 +00005068- Issue #2542: Now that issubclass() may call arbitrary code, ensure that
5069 PyErr_ExceptionMatches returns 0 when an exception occurs there.
5070
Antoine Pitrou92f82162008-07-25 22:22:08 +00005071- Issue #1819: function calls with several named parameters are now on
5072 average 35% faster (as measured by pybench).
5073
Amaury Forgeot d'Arce4921fe2008-07-21 22:00:38 +00005074- Issue #2378: An unexpected UnboundLocalError or NameError could appear when
5075 the python debugger steps into a class statement: the free variables (local
5076 variables defined in an outer scope) would be deleted from the outer scope.
5077
Gregory P. Smith0470bab2008-07-22 04:46:32 +00005078- Issue #2620: Overflow checking when allocating or reallocating memory
5079 was not always being done properly in some python types and extension
5080 modules. PyMem_MALLOC, PyMem_REALLOC, PyMem_NEW and PyMem_RESIZE have
5081 all been updated to perform better checks and places in the code that
5082 would previously leak memory on the error path when such an allocation
5083 failed have been fixed.

5086-------
5087
Hirokazu Yamamoto838c79f2008-08-20 13:14:07 +00005088- Issue #3612: Added some missing basic types in ctypes.wintypes.
5089
Benjamin Petersone977ad42008-08-20 01:42:01 +00005090- The methods ``is_in_tuple()``, ``is_vararg()``, and ``is_keywordarg()`` of
5091 symtable.Symbol have been deprecated for removal in 3.0 and the next release.
5092
Amaury Forgeot d'Arc351ffb82008-08-18 19:23:47 +00005093- Issue #2234: distutils failed for some versions of the cygwin compiler. The
5094 version reported by these tools does not necessarily follow the python
5095 version numbering scheme, so the module is less strict when parsing it.
5096
Nick Coghlanf70385a2008-08-18 12:42:46 +00005097- Issue #2235: Added Py3k warnings for types which will become unhashable
5098 under the stricter __hash__ inheritance rules in 3.0. Several types
5099 which did not meet the rules for hash invariants and were already
5100 unhashable in 3.0 have now been explicitly flagged as unhashable in
5101 2.6 as well (collections.Mapping, collections.Set, unittest.TestSuite,
5102 xml.dom.minidom.NamedNodeMap, numbers.Number, UserList.UserList)
5103
Brett Cannon88f801d2008-08-18 00:46:22 +00005104- Update __all__ for cookielib, csv, os, urllib2, and weakref to include things
5105 imported into the module but exposed as part of the module's API.
5106
Brett Cannon7b96f072008-08-18 00:41:11 +00005107- Remove an unneeded import of abc.ABCMeta from 'inspect'.
5108
Brett Cannon46225e72008-08-18 00:36:52 +00005109- Remove unneeded imports of 'sys' and 'warnings' from 'io'.

5230-----------------
5231
Georg Brandl3e483f62008-07-16 22:57:41 +00005232- Issue #3156: Fix inconsistent behavior of the bytearray type: all
5233 its methods now allow for items objects that can be converted to
5234 an integer using operator.index().
5235
Mark Dickinson64b7e502008-07-16 09:40:03 +00005236- Issue #3360: Fix incorrect parsing of '020000000000.0', which
5237 produced a ValueError instead of giving the correct float.
5238
Eric Smitha5fa5a22008-07-16 00:11:49 +00005239- Issue #3083: Add alternate (#) formatting for bin, oct, hex output
5240 for str.format(). This adds the prefix 0b, 0o, or 0x, respectively.
5241
Mark Dickinson7103aa42008-07-15 19:08:33 +00005242- Issue #3008: the float type has a new instance method 'float.hex'
5243 and a new class method 'float.fromhex' to convert floating-point
5244 numbers to and from hexadecimal strings, respectively.
5245
Nick Coghlan6d6bd442008-07-15 15:40:22 +00005246- Issue #2235: __hash__ is once again inherited by default. To allow
5247 collections.Hashable to remain meaningful in the presence of the
5248 default hash implementation (object.__hash__), it is now possible
5249 to explicit block inheritance of hash by setting __hash__=None at
5250 the Python level, or tp_hash=PyObject_HashNotImplemented at the C
5251 level.
5252
Nick Coghlanb028f502008-07-13 14:52:36 +00005253- Issue #3221: Issue a RuntimeWarning instead of raising SystemError if
5254 the parent module cannot be found while performing an absolute import.
5255 This means that an incorrectly defined __package__ attribute will
5256 now only prevent relative imports in that module rather than causing
5257 all imports from that module to fail.
5258
Nick Coghlan14ff9942008-07-08 14:21:42 +00005259- Issue #2517: Allow unicode messages in Exceptions again by correctly
5260 bypassing the instance dictionary when looking up __unicode__ on
5261 new-style classes.

5269 another thread's dictionary.
5270
Mark Dickinson1ec2fcd2008-06-20 14:53:43 +00005271- Issue #3004: Minor change to slice.indices(): the start and stop
5272 arguments are now treated identically, making the behaviour easier
5273 to describe and understand. For example, slice(None, -10,
5274 1).indices(9) now returns (0, 0, 1) instead of (0, -1, 1), and
5275 slice(None, 10, -1).indices(10) returns (9, 9, -1) instead of (9,
5276 10, -1).
5277
Georg Brandl278fc502008-07-19 12:46:12 +00005278- Issue #3219: Calling a function with repeated keyword arguments,
5279 f(a=2, a=23), would not cause a syntax error. This was a regression
5280 from 2.4 caused by the switch to the new compiler.

Georg Brandl278fc502008-07-19 12:46:12 +00005282- Issue #2862: Make int and float freelist management consistent with
5283 other freelists. Changes their CompactFreeList apis into

5291 error when they failed.
5292
Martin v. Löwisaabf4042008-08-02 07:20:25 +00005293- Issue #799428: Fix Tkinter.Misc._nametowidget to unwrap Tcl command objects.

Amaury Forgeot d'Arc0f7cddc2008-07-06 21:34:39 +00005318- Issue #839496: SimpleHTTPServer used to open text files in text mode. This is
5319 both unnecessary (HTTP allows text content to be sent in several forms) and
Andrew M. Kuchlingcc3f2b12008-07-10 14:43:31 +00005320 wrong because the actual transmitted size could differ from the
Amaury Forgeot d'Arc0f7cddc2008-07-06 21:34:39 +00005321 content-length. The problem had been corrected in the 2.4 branch, but never
5322 merged into trunk.

Nick Coghlanc060b0e2008-07-02 13:09:19 +00005337- Issue #3190: Pydoc now hides the automatic module attribute __package__ (the

5680 large to fit in a C long. ldexp(x, n) now returns a zero (with
5681 suitable sign) if n is large and negative; previously, it raised
5682 OverflowError.

Ronald Oussoren5640ce22008-06-05 12:58:24 +00005728- On MacOS X it is now possible to install the framework in 64-bit
5729 mode or even as a 4-way universal binary (that is, PPC, i386,
Georg Brandl5cc774e2008-06-11 20:28:06 +00005730 PPC64 and x86_64 support in one binary).
Ronald Oussoren5640ce22008-06-05 12:58:24 +00005731
5732 This is controlled by the configure argument ``--with-universal-archs``:
5733
5734 - ``--with-universal-archs=all``: install 4-way universal
5735
5736 - ``--with-universal-archs=32-bit``: install 2-way universal, 32-bit (the default)
5737
5738 - ``--with-universal-archs=64-bit``: install 2-way universal, 64-bit
5739
5740 This option should be used in combination with ``--enable-universalsdk=``.
5741
5742 NOTE: 64-bit and 4-way builds are only suppported on Mac OS X 10.5 (or later).

Georg Brandl3ee81df2008-05-17 18:14:43 +00005792- Issue #1631171: Re-implement the 'warnings' module in C (the
5793 original Python code has been kept as backup). This will allow for
5794 using the 'warning's machinery in such places as the parser where
5795 use of pure Python code is not possible. Both the ``showarning()``
5796 and ``formatwarning()`` gain an optional 'line' argument which is
5797 not called by default for backwards-compatibility reasons. Setting
5798 ``warnings.showwarning()`` to an implementation that lacks support
5799 for the ``line`` argument will raise a DeprecationWarning.

Georg Brandl3ee81df2008-05-17 18:14:43 +00005862- Issue #2550: The approach used by client/server code for obtaining
5863 ports to listen on in network-oriented tests has been refined in an
5864 effort to facilitate running multiple instances of the entire
5865 regression test suite in parallel without issue.
5866 test_support.bind_port() has been fixed such that it will always
5867 return a unique port -- which wasn't always the case with the
5868 previous implementation, especially if socket options had been set
5869 that affected address reuse (i.e. SO_REUSEADDR, SO_REUSEPORT). The
5870 new implementation of bind_port() will actually raise an exception
5871 if it is passed an AF_INET/SOCK_STREAM socket with either the
5872 SO_REUSEADDR or SO_REUSEPORT socket option set. Furthermore, if
5873 available, bind_port() will set the SO_EXCLUSIVEADDRUSE option on
5874 the socket it's been passed. This currently only applies to
5875 Windows. This option prevents any other sockets from binding to the
5876 host/port we've bound to, thus removing the possibility of the
5877 'non-deterministic' behaviour, as Microsoft puts it, that occurs
5878 when a second SOCK_STREAM socket binds and accepts to a host/port
5879 that's already been bound by another socket. The optional preferred
5880 port parameter to bind_port() has been removed. Under no
5881 circumstances should tests be hard coding ports!
5882
5883 test_support.find_unused_port() has also been introduced, which will
5884 pass a temporary socket object to bind_port() in order to obtain an
5885 unused port. The temporary socket object is then closed and
5886 deleted, and the port is returned. This method should only be used
5887 for obtaining an unused port in order to pass to an external program
5888 (i.e. the -accept [port] argument to openssl's s_server mode) or as
5889 a parameter to a server-oriented class that doesn't give you direct
5890 access to the underlying socket used.
5891
5892 Finally, test_support.HOST has been introduced, which should be used
5893 for the host argument of any relevant socket calls (i.e. bind and
5894 connect).
Trent Nelsone41b0062008-04-08 23:47:30 +00005895
5896 The following tests were updated to following the new conventions:
Georg Brandl3ee81df2008-05-17 18:14:43 +00005897 test_socket, test_smtplib, test_asyncore, test_ssl, test_httplib,
Trent Nelsone41b0062008-04-08 23:47:30 +00005898 test_poplib, test_ftplib, test_telnetlib, test_socketserver,
5899 test_asynchat and test_socket_ssl.
5900
Georg Brandl3ee81df2008-05-17 18:14:43 +00005901 It is now possible for multiple instances of the regression test
5902 suite to run in parallel without issue.

Amaury Forgeot d'Arc9a0d3462008-03-23 09:55:29 +00005956- Issue #1477: With narrow Unicode builds, the unicode escape sequence
Georg Brandl3ee81df2008-05-17 18:14:43 +00005957 \Uxxxxxxxx did not accept values outside the Basic Multilingual
5958 Plane. This affected raw unicode literals and the
5959 'raw-unicode-escape' codec. Now UTF-16 surrogates are generated in
5960 this case, like normal unicode literals and the 'unicode-escape'
5961 codec.

Eric Smitha73fbe72008-02-23 03:09:44 +00006181- Added the future_builtins module, which contains hex() and oct().
6182 These are the PEP 3127 version of these functions, designed to be
6183 compatible with the hex() and oct() builtins from Python 3.0. They
6184 differ slightly in their output formats from the existing, unchanged
6185 Python 2.6 builtins. The expected usage of the future_builtins
6186 module is:
6187 from future_builtins import hex, oct
6188
Eric Smith7ef40bf2008-02-20 23:34:22 +00006189- Issue #1600: Modifed PyOS_ascii_formatd to use at most 2 digit
6190 exponents for exponents with absolute value < 100. Follows C99
6191 standard. This is a change on Windows, which would use 3 digits.
6192 Also, added 'n' to the formats that PyOS_ascii_formatd understands,
6193 so that any alterations it does to the resulting string will be
6194 available in stringlib/formatter.h (for float.__format__).
6195
Eric Smith5a3c1352008-02-19 13:21:56 +00006196- Implemented PEP 3101, Advanced String Formatting. This adds a new
6197 builtin format(); a format() method for str and unicode; a
6198 __format__() method to object, str, unicode, int, long, float, and
6199 datetime; the class string.Formatter; and the C API
6200 PyObject_Format().
6201
Georg Brandl3ee81df2008-05-17 18:14:43 +00006202- Fixed several potential crashes, all caused by specially crafted
6203 __del__ methods exploiting objects in temporarily inconsistent
6204 state.
Amaury Forgeot d'Arc632fad32008-02-16 20:55:24 +00006205
Vinay Sajipb7edfc42008-04-02 21:10:23 +00006206- Issue #2115: Important speedup in setting __slot__ attributes. Also
Georg Brandl3ee81df2008-05-17 18:14:43 +00006207 prevent a possible crash: an Abstract Base Class would try to access
6208 a slot on a registered virtual subclass.
Amaury Forgeot d'Arc60d6c7f2008-02-15 21:22:45 +00006209
Georg Brandl3ee81df2008-05-17 18:14:43 +00006210- Fixed repr() and str() of complex numbers with infinity or nan as
6211 real or imaginary part.

Georg Brandl3ee81df2008-05-17 18:14:43 +00006213- Clear all free lists during a gc.collect() of the highest generation
6214 in order to allow pymalloc to free more arenas. Python may give back
6215 memory to the OS earlier.
Christian Heimes3b718a72008-02-14 12:47:33 +00006216
Georg Brandl3ee81df2008-05-17 18:14:43 +00006217- Issue #2045: Fix an infinite recursion triggered when printing a
6218 subclass of collections.defaultdict, if its default_factory is set
6219 to a bound method.
Amaury Forgeot d'Arcb01aa432008-02-08 00:56:02 +00006220
Christian Heimesf75dbef2008-02-08 00:11:31 +00006221- Fixed a minor memory leak in dictobject.c. The content of the free
6222 list was not freed on interpreter shutdown.
6223
Georg Brandl21e99f42010-03-07 15:23:59 +00006224- Limit free list of method and built-in function objects to 256
Georg Brandl3ee81df2008-05-17 18:14:43 +00006225 entries each.
Christian Heimes6075a822008-02-06 12:44:34 +00006226
Georg Brandl3ee81df2008-05-17 18:14:43 +00006227- Patch #1953: Added ``sys._compact_freelists()`` and the C API
6228 functions ``PyInt_CompactFreeList`` and ``PyFloat_CompactFreeList``
Christian Heimes422051a2008-02-04 18:00:12 +00006229 to compact the internal free lists of pre-allocted ints and floats.
6230
Georg Brandl3ee81df2008-05-17 18:14:43 +00006231- Issue #1983: Fixed return type of fork(), fork1() and forkpty()
6232 calls. Python expected the return type int but the fork familie
6233 returns pi_t.
Christian Heimes951cc0f2008-01-31 23:08:23 +00006234
Georg Brandl3ee81df2008-05-17 18:14:43 +00006235- Issue #1678380: Fix a bug that identifies 0j and -0j when they
6236 appear in the same code unit.

Georg Brandl3ee81df2008-05-17 18:14:43 +00006247- Patch #1473257: generator objects gain a gi_code attribute. This is
6248 the same object as the func_code attribute of the function that
6249 produced the generator.
Georg Brandl0cdf9a32008-01-26 14:14:20 +00006250
Georg Brandl3ee81df2008-05-17 18:14:43 +00006251- Issue #1920: "while 0" statements were completely removed by the
6252 compiler, even in the presence of an "else" clause, which is
6253 supposed to be run when the condition is false. Now the compiler
6254 correctly emits bytecode for the "else" suite.
Amaury Forgeot d'Arc31eaafe2008-01-24 22:59:25 +00006255
Guido van Rossumeead05f2008-01-24 18:21:02 +00006256- A few crashers fixed: weakref_in_del.py (issue #1377858);
6257 loosing_dict_ref.py (issue #1303614, test67.py);
6258 borrowed_ref_[34].py (not in tracker).
6259
Vinay Sajipd7cf32e2008-01-24 12:43:33 +00006260- Issue #1069410: The "can't load dll" message box on Windows is
Christian Heimesb2302ba2008-01-23 17:15:06 +00006261 suppressed while an extension is loaded by calling SetErrorMode in
6262 dynload_win.c. The error is still reported properly.
6263
Georg Brandl3ee81df2008-05-17 18:14:43 +00006264- Issue #1915: Python compiles with --enable-unicode=no again. However
Christian Heimes082c9b02008-01-23 14:20:50 +00006265 several extension methods and modules do not work without unicode
6266 support.
6267
Georg Brandl26543b12008-01-21 18:36:51 +00006268- Issue #1882: when compiling code from a string, encoding cookies in the
6269 second line of code were not always recognized correctly.
6270

6272
Georg Brandl6caad7d2008-01-26 14:19:22 +00006273- Issue #1865: ``bytes`` as an alias for ``str`` and b"" as an alias "" were
Christian Heimes288e89a2008-01-18 18:24:07 +00006274 added.
6275
Christian Heimesc94e2b52008-01-14 04:13:37 +00006276- sys.float_info / PyFloat_GetInfo: The floating point information
6277 object was converted from a dict to a specialized structseq object.
6278
Georg Brandl3ee81df2008-05-17 18:14:43 +00006279- Patch #1816: Added sys.flags structseq. It exposes the status of
6280 most command line arguments and PYTHON* environment variables.
Christian Heimesf31b69f2008-01-14 03:42:48 +00006281
Georg Brandl3ee81df2008-05-17 18:14:43 +00006282- Objects/structseq.c: Implemented new structseq representation. The
6283 patch makes structseqs (e.g. the return value of os.stat) more
6284 readable.
Christian Heimes9c201962008-01-14 03:33:52 +00006285
Georg Brandl3ee81df2008-05-17 18:14:43 +00006286- Patch #1700288: added a type attribute cache that caches method
6287 accesses, resulting in speedups in heavily object-oriented code.
Amaury Forgeot d'Arce4c270c2008-01-14 00:29:41 +00006288
Neal Norwitz3fc15b82008-01-10 05:42:58 +00006289- Bug #1776: __import__() no longer accepts filenames on any platform.
6290 The first parameter to __import__() must be a valid module name.
Christian Heimes3403f152008-01-09 19:56:33 +00006291
Georg Brandlaed6c662008-01-07 17:25:53 +00006292- Patch #1668: renamed THREADDEBUG envvar to PYTHONTHREADDEBUG.
6293
Georg Brandl3ee81df2008-05-17 18:14:43 +00006294- Patch #602345: Add -B command line option, PYTHONDONTWRITEBYTECODE
6295 envvar and sys.dont_write_bytecode attribute. All these can be set
6296 to forbid Python to attempt to write compiled bytecode files.
Georg Brandl2da0fce2008-01-07 17:09:35 +00006297
Georg Brandl3ee81df2008-05-17 18:14:43 +00006298- Improve some exception messages when Windows fails to load an
6299 extension module. Now we get for example '%1 is not a valid Win32
6300 application' instead of 'error code 193'.
Amaury Forgeot d'Arce0b76952008-01-04 02:04:15 +00006301

Christian Heimes0a8143f2007-12-18 23:22:54 +00006307- Issue #1635: Platform independent creation and representation of NaN
Georg Brandl3ee81df2008-05-17 18:14:43 +00006308 and INF. float("nan"), float("inf") and float("-inf") now work on
6309 every platform with IEEE 754 semantics.
Christian Heimes0a8143f2007-12-18 23:22:54 +00006310
Georg Brandl3ee81df2008-05-17 18:14:43 +00006311- Compiler now generates simpler and faster code for dictionary
6312 literals. The oparg for BUILD_MAP now indicates an estimated
6313 dictionary size. There is a new opcode, STORE_MAP, for adding
6314 entries to the dictionary.

Georg Brandl3ee81df2008-05-17 18:14:43 +00006343- Patch #1739468: Directories and zipfiles containing a __main__.py
6344 file can now be directly executed by passing their name to the
6345 interpreter. The directory/zipfile is automatically inserted as the
6346 first entry in sys.path.
Nick Coghlan327a39b2007-11-18 11:56:28 +00006347
Georg Brandl3ee81df2008-05-17 18:14:43 +00006348- Issue #1265: Fix a problem with sys.settrace, if the tracing
6349 function uses a generator expression when at the same time the
6350 executed code is closing a paused generator.
Amaury Forgeot d'Arc0d75f092007-11-13 21:54:28 +00006351
Raymond Hettinger1760c8a2007-11-08 02:52:43 +00006352- sets and frozensets now have an isdisjoint() method.
6353
Raymond Hettinger3f8caa32007-10-24 01:28:33 +00006354- optimize the performance of builtin.sum().
6355

6357
Georg Brandl21e99f42010-03-07 15:23:59 +00006358- The enumerate() built-in function is no longer bounded to sequences
Georg Brandl3ee81df2008-05-17 18:14:43 +00006359 smaller than LONG_MAX. Formerly, it raised an OverflowError. Now,
6360 automatically shifts from ints to longs.
Raymond Hettinger8f669372007-10-03 21:18:11 +00006361
Georg Brandl3ee81df2008-05-17 18:14:43 +00006362- Issue #1686386: Tuple's tp_repr did not take into account the
6363 possibility of having a self-referential tuple, which is possible
6364 from C code. Nor did object's tp_str consider that a type's tp_str
6365 could do something that could lead to an inifinite recursion.
6366 Py_ReprEnter() and Py_EnterRecursiveCall(), respectively, fixed the
6367 issues.
Brett Cannon0b14f242007-09-30 19:45:10 +00006368
Georg Brandl3ee81df2008-05-17 18:14:43 +00006369- Issue #1164: It was possible to trigger deadlock when using the
6370 'print' statement to write to a file since the GIL was not released
6371 as needed. Now PyObject_Print() does the right thing along with
6372 various tp_print implementations of the built-in types and those in
6373 the collections module.
Brett Cannon01531592007-09-17 03:28:34 +00006374
Georg Brandl3ee81df2008-05-17 18:14:43 +00006375- Issue #1147: Exceptions were directly allowing string exceptions in
6376 their throw() method even though string exceptions no longer
6377 allowed.
Brett Cannon4c20bc42007-09-11 21:02:28 +00006378
Georg Brandl3ee81df2008-05-17 18:14:43 +00006379- Issue #1096: Prevent a segfault from getting the repr of a very
6380 deeply nested list by using the recursion counter.
Brett Cannona0c05512007-09-10 21:38:27 +00006381
Brett Cannon1e534b52007-09-07 04:18:30 +00006382- Issue #1202533: Fix infinite recursion calls triggered by calls to
Georg Brandl3ee81df2008-05-17 18:14:43 +00006383 PyObject_Call() never calling back out to Python code to trigger
6384 recursion depth updates/checks. Required the creation of a static
6385 RuntimeError instance in case normalizing an exception put the
6386 recursion check value past its limit. Fixes crashers
6387 infinite_rec_(1|2|4|5).py.
Brett Cannon1e534b52007-09-07 04:18:30 +00006388

Neal Norwitz0ac60192007-05-27 04:08:54 +00006402- Add new attribute names for function objects. All the func_* become
Georg Brandl3ee81df2008-05-17 18:14:43 +00006403 __*__ attributes. (Some already existed, e.g., __doc__ and
6404 __name__.)
Neal Norwitz0ac60192007-05-27 04:08:54 +00006405
Neal Norwitz8b2bfbc2007-05-23 06:35:32 +00006406- Add -3 option to the interpreter to warn about features that are
6407 deprecated and will be changed/removed in Python 3.0.
6408
Georg Brandl2134e752007-05-21 20:34:16 +00006409- Patch #1686487: you can now pass any mapping after '**' in function
6410 calls.
6411
Collin Winter62903052007-05-18 23:11:24 +00006412- except clauses may now be spelled either "except E, target:" or
Georg Brandl3ee81df2008-05-17 18:14:43 +00006413 "except E as target:". This is to provide forwards compatibility
6414 with Python 3.0.

Georg Brandl3ee81df2008-05-17 18:14:43 +00006418- Issue #1303614: don't expose object's __dict__ when the dict is
Georg Brandl21e99f42010-03-07 15:23:59 +00006419 inherited from a built-in base.
Armin Rigo9790a272007-05-02 19:23:31 +00006420
Vinay Sajip8549ce32007-05-06 17:53:37 +00006421- When __slots__ are set to a unicode string, make it work the same as
Neal Norwitzcbd9ee62007-04-14 05:25:50 +00006422 setting a plain string, ie don't expand to single letter identifiers.
6423
Raymond Hettinger13936692007-04-11 18:40:58 +00006424- Request #1191699: Slices can now be pickled.
6425
Raymond Hettinger4db5fe92007-04-12 04:10:00 +00006426- Request #1193128: str.translate() now allows a None argument for
6427 translations that only remove characters without re-mapping the
6428 remaining characters.
6429
Georg Brandl5cb76c12007-03-21 09:00:39 +00006430- Patch #1682205: a TypeError while unpacking an iterable is no longer
6431 masked by a generic one with the message "unpack non-sequence".
6432

6434
Guido van Rossum143b5642007-03-23 04:58:42 +00006435- Bug #1683368: The object.__init__() and object.__new__() methods are
6436 now stricter in rejecting excess arguments. The only time when
6437 either allows excess arguments is when it is not overridden and the
6438 other one is. For backwards compatibility, when both are
6439 overridden, it is a deprecation warning (for now; maybe a Py3k
Guido van Rossum234b1ff2007-03-23 19:39:01 +00006440 warning later). Also, type.__init__() insists on the same signature
6441 as supported by type.__new__().

Georg Brandl3ee81df2008-05-17 18:14:43 +00006443- Patch #1675423: PyComplex_AsCComplex() now tries to convert an
6444 object to complex using its __complex__() method before falling back
6445 to the __float__() method. Therefore, the functions in the cmath
6446 module now can operate on objects that define a __complex__()
6447 method.

6467
Georg Brandl871f1bc2007-03-12 13:17:36 +00006468- The dir() function has been extended to call the __dir__() method on
Georg Brandl3ee81df2008-05-17 18:14:43 +00006469 its argument, if it exists. If not, it will work like before. This
6470 allows customizing the output of dir() in the presence of a
6471 __getattr__().

Georg Brandlaa2321b2007-03-07 00:40:28 +00006483- Patch #703779: unset __file__ in __main__ after running a file. This
Georg Brandl3ee81df2008-05-17 18:14:43 +00006484 makes the filenames the warning module prints much more sensible
6485 when a PYTHONSTARTUP file is used.

Georg Brandl2c1375c2006-10-12 11:27:59 +00006553- Bug #1545497: when given an explicit base, int() did ignore NULs
6554 embedded in the string to convert.
6555
Georg Brandl846f73a2006-10-08 07:11:54 +00006556- Bug #1569998: break inside a try statement (outside a loop) is now

Georg Brandl3ee81df2008-05-17 18:14:43 +00006604 generator expressions (x for x, in ... ) works again. Fixing this
6605 problem required changing the .pyc magic number. This means that
6606 .pyc files generated before 2.5c2 will be regenerated.

Georg Brandl3ee81df2008-05-17 18:14:43 +00007409- The implementation of UnicodeError objects has been simplified
7410 (start and end attributes are now stored directly as Py_ssize_t
7411 members).

Georg Brandl3ee81df2008-05-17 18:14:43 +00007413- Issue #829951: In the smtplib module, SMTP.starttls() now complies
7414 with RFC 3207 and forgets any knowledge obtained from the server not
7415 obtained from the TLS negotiation itself. Patch contributed by Bill
7416 Fenner.
Gregory P. Smith2b3ba582008-01-17 08:03:17 +00007417
Georg Brandl3ee81df2008-05-17 18:14:43 +00007418- Issue #1339: The smtplib.SMTP class has been refactored a bit such
Gregory P. Smithbde4ae42008-01-17 08:35:49 +00007419 that the SMTP.starttls() caller no longer needs to call ehlo()
7420 beforehand. SMTP.starttls() now raises an exception of the server
Georg Brandl3ee81df2008-05-17 18:14:43 +00007421 does not claim to support starttls. Adds the
7422 SMTP.ehlo_or_helo_if_needed() method. Patch contributed by Bill
7423 Fenner.

7503 complex, tuple, list, dict, set, and frozenset. Formerly, it would
7504 silently miscode subclasses of those types. Now, it raises a
7505 ValueError instead.
Raymond Hettinger12e94202007-11-07 01:13:09 +00007506

Georg Brandl3ee81df2008-05-17 18:14:43 +00007521 time so that opening a database previously created with the DB_DUP
7522 or DB_DUPSORT flag set will keep the proper behavior on subsequent
7523 opens. Specifically: dictionary assignment to a DB object will
7524 replace all values for a given key when the database allows
7525 duplicate values. DB users should use DB.put(k, v) when they want
7526 to store duplicates; not DB[k] = v.
Gregory P. Smithec10a4a2007-11-05 02:32:26 +00007527

7533 characters with ASCII value less than 32. Also, it correctly quotes
7534 dots only if they occur on a single line, as opposed to the previous
7535 behavior of quoting dots if they are the second character of any
7536 line.
Georg Brandl4aef7272007-03-13 22:49:43 +00007537
