83 handles the 'bye' correctly.
84

1442 default was specified and the argument was given as well. This was
1443 especially problematic for the FileType type, as a default file would always
1444 be opened, even if a file argument was specified on the command line.

1701 In particular, fix extension module build failures when trying to use
1702 32-bit-only installer Pythons on systems with Xcode 4 (currently
1703 OS X 10.8, 10.7, and optionally 10.6).
1704 * Backport 3.3.0 fixes to 2.7 branch (for release in 2.7.4)
1705 * Since Xcode 4 removes ppc support, extension module builds now
1706 check for ppc compiler support and by default remove ppc and
1707 ppc64 archs when they are not available.
1708 * Extension module builds now revert to using system installed
1709 headers and libs (/usr and /System/Library) if the SDK used
1710 to build the interpreter is not installed or has moved.
1711 * Try to avoid building extension modules with deprecated
1712 and problematic Apple llvm-gcc compiler. If original compiler
1713 is not available, use clang instead by default.

Mark Dickinsondbbed042011-09-19 16:38:08 +01002064- Issue #12973: Fix overflow checks that invoked undefined behaviour in
2065 int.__pow__. These overflow checks were causing int.__pow__ to produce
2066 incorrect results with recent versions of Clang, as a result of the
Mark Dickinsona96b0d12011-09-24 09:01:16 +01002067 compiler optimizing the check away. Also fix similar overflow checks
2068 in list_repeat (listobject.c) and islice_next (itertoolsmodule.c). These
2069 bugs caused test failures with recent versions of Clang.

2081 cleared by the garbage collector. This fixes a segfault when an instance
2082 and its type get caught in a reference cycle, and the instance's

Florent Xiclunac2279652012-02-12 14:49:03 +01002137- Issue #13994: Earlier partial revert of Distutils enhancements in 2.7
Ned Deilyc47a4592012-02-11 20:40:24 +01002138 has left two versions of customize_compiler, the original in
2139 distutils.sysconfig and another copy in distutils.ccompiler, with some

2142 is the case in 3.x.

Ned Deily0d0ea482012-02-10 12:59:06 +01002144- Issue #13590: On OS X 10.7 and 10.6 with Xcode 4.2, building
2145 Distutils-based packages with C extension modules may fail because
2146 Apple has removed gcc-4.2, the version used to build python.org
2147 64-bit/32-bit Pythons. If the user does not explicitly override
2148 the default C compiler by setting the CC environment variable,
2149 Distutils will now attempt to compile extension modules with clang
2150 if gcc-4.2 is required but not found. Also as a convenience, if
2151 the user does explicitly set CC, substitute its value as the default
2152 compiler in the Distutils LDSHARED configuration variable for OS X.
2153 (Note, the python.org 32-bit-only Pythons use gcc-4.0 and the 10.4u
2154 SDK, neither of which are available in Xcode 4. This change does not
2155 attempt to override settings to support their use with Xcode 4.)

Ned Deily87e82bb2011-06-28 19:52:59 -07002405- Issue #9516: On Mac OS X, change Distutils to no longer globally attempt to
2406 check or set the MACOSX_DEPLOYMENT_TARGET environment variable for the
2407 interpreter process. This could cause failures in non-Distutils subprocesses
2408 and was unreliable since tests or user programs could modify the interpreter
Ezio Melotti302ad8d2013-01-19 19:44:58 +02002409 environment after Distutils set it. Instead, have Distutils set the
Ned Deily87e82bb2011-06-28 19:52:59 -07002410 deployment target only in the environment of each build subprocess. It is
2411 still possible to globally override the default by setting
2412 MACOSX_DEPLOYMENT_TARGET before launching the interpreter; its value must be
2413 greater or equal to the default value, the value with which the interpreter
2414 was built.

2443 updating the check interval, so if the user decreases the check interval,
2444 the ticker doesn't have to wind down to zero from the old starting point
2445 before the new interval takes effect. And if the user increases the
2446 interval, it makes sure the new limit takes effect right away rather have an
2447 early task switch before recognizing the new interval.

3428 This prevents user-created self-referencing ordered dictionaries from
3429 becoming permanently uncollectable GC garbage. The downside is that
3430 removing __del__ means that the internal doubly-linked list has to wait for
3431 GC collection rather than freeing memory immediately when the refcnt drops
3432 to zero.

3889
Ezio Melottiab2eb0e2010-06-05 19:21:32 +00003890- Issue #8271: during the decoding of an invalid UTF-8 byte sequence, only the
3891 start byte and the continuation byte(s) are now considered invalid, instead
3892 of the number of bytes specified by the start byte.
3893 E.g.: '\xf1\x80AB'.decode('utf-8', 'replace') now returns u'\ufffdAB' and
3894 replaces with U+FFFD only the start byte ('\xf1') and the continuation byte
3895 ('\x80') even if '\xf1' is the start byte of a 4-bytes sequence.
3896 Previous versions returned a single u'\ufffd'.

3902 gets ignored.

Mark Dickinson4ca7c3c2010-05-30 13:18:10 +00003904- Issue #8748: Fix two issues with comparisons between complex and integer
3905 objects. (1) The comparison could incorrectly return True in some cases
3906 (2**53+1 == complex(2**53) == 2**53), breaking transivity of equality.
3907 (2) The comparison raised an OverflowError for large integers, leading
3908 to unpredictable exceptions when combining integers and complex objects
3909 in sets or dicts.

Mark Dickinson81336372010-05-30 12:12:25 +00003911- Issue #5211: Implicit coercion for the complex type is now completely

Georg Brandlfee0f442010-05-22 21:26:21 +00004291- Issue #7994: Issue a PendingDeprecationWarning if object.__format__ is called
4292 with a non-empty format string. This is an effort to future-proof user
4293 code. If a derived class does not currently implement __format__ but later
4294 adds its own __format__, it would most likely break user code that had
Antoine Pitrou01a196a2011-01-02 20:05:11 +00004295 supplied a format string. This will be changed to a DeprecationWarning in
Georg Brandlfee0f442010-05-22 21:26:21 +00004296 Python 3.3 and it will be an error in Python 3.4.

Mark Dickinson8efef5c2010-01-12 22:23:56 +00004744
Georg Brandlba83f822010-03-14 09:50:54 +00004745 (1) a serious 'wrong output' bug that could occur for long (> 40 digit) input
4746 strings,
4747 (2) a crash in dtoa.c that occurred in debug builds when parsing certain long
4748 numeric strings corresponding to subnormal values,
4749 (3) a memory leak for some values large enough to cause overflow, and
4750 (4) a number of flaws that could lead to incorrectly rounded results.

Georg Brandlba83f822010-03-14 09:50:54 +00004789 file position when calling `truncate()`. It would previously change the file
4790 position to the given argument, which goes against the tradition of
Antoine Pitrouf3fa0742010-01-31 22:26:04 +00004791 ftruncate() and other truncation APIs. Patch by Pascal Chambon.

4794 class used to represent files stored inside an archive. The new
4795 implementation is significantly faster and can be wrapped in a
4796 ``io.BufferedReader`` object for more speedups. It also solves an issue
4797 where interleaved calls to ``read()`` and ``readline()`` give wrong results.

4810 encoded string for them. This ensures that the upload and register commands
4811 send the correct values to PyPI without any error.

4885Core and Builtins
4886-----------------
4887
Georg Brandlba83f822010-03-14 09:50:54 +00004888- The ``__complex__()`` method is now looked up on the class of instances to
4889 make it consistent with other special methods.
Benjamin Petersonecdae192010-01-04 00:43:01 +00004890
Antoine Pitrou5b7139a2010-01-02 21:12:58 +00004891- Issue #7462: Implement the stringlib fast search algorithm for the `rfind`,
4892 `rindex`, `rsplit` and `rpartition` methods. Patch by Florent Xicluna.
4893
Mark Dickinson1b34d252010-01-01 17:27:30 +00004894- Issue #5080: A number of functions and methods previously produced a
Georg Brandlba83f822010-03-14 09:50:54 +00004895 DeprecationWarning when passed a float argument where an integer was expected.
4896 These functions and methods now raise TypeError instead. The majority of the
4897 effects of this change are in the extension modules, but some core functions
4898 and methods are affected: notably the 'chr', 'range' and 'xrange' builtins,
4899 and many unicode/str methods.

4910 used to drop the time part of the result.
4911
Georg Brandlba83f822010-03-14 09:50:54 +00004912- Issue #1811: Improve accuracy and cross-platform consistency for true division
4913 of integers: the result of a/b is now correctly rounded for ints a and b (at
4914 least on IEEE 754 platforms), and in particular does not depend on the
4915 internal representation of a long.

4923
Georg Brandlba83f822010-03-14 09:50:54 +00004924 These executables now work properly with the arch(1) command: ``arch -ppc
4925 python`` will start a universal binary version of python in PPC mode (unlike

Georg Brandlba83f822010-03-14 09:50:54 +00005081- Issue #7117: ``repr(x)`` for a float x returns a result based on the shortest
5082 decimal string that's guaranteed to round back to x under correct rounding
5083 (with round-half-to-even rounding mode). Previously it gave a string based on
5084 rounding x to 17 decimal digits. repr(x) for a complex number behaves
5085 similarly. On platforms where the correctly-rounded strtod and dtoa code is
5086 not supported (see below), repr is unchanged.
Mark Dickinsonb678de82009-11-19 18:41:49 +00005087
Georg Brandlba83f822010-03-14 09:50:54 +00005088- Issue #7117: On almost all platforms: float-to-string and string-to-float
5089 conversions within Python are now correctly rounded. Places these conversions
5090 occur include: str for floats and complex numbers; the float and complex
5091 constructors; old-style and new-style numeric formatting; serialization and
5092 deserialization of floats and complex numbers using marshal, pickle and json;
5093 parsing of float and imaginary literals in Python code; Decimal-to-float
5094 conversion.
Mark Dickinsonb678de82009-11-19 18:41:49 +00005095
Georg Brandlba83f822010-03-14 09:50:54 +00005096 The conversions use a Python-adapted version of David Gay's well-known dtoa.c,
5097 providing correctly-rounded strtod and dtoa C functions. This code is
5098 supported on Windows, and on Unix-like platforms using gcc, icc or suncc as
5099 the C compiler. There may be a small number of platforms on which correct
5100 operation of this code cannot be guaranteed, so the code is not used: notably,
5101 this applies to platforms where the C double format is not IEEE 754 binary64,
5102 and to platforms on x86 hardware where the x87 FPU is set to 64-bit precision
5103 and Python's configure script is unable to determine how to change the FPU
5104 precision. On these platforms conversions use the platform strtod and dtoa,
5105 as before.

Georg Brandlba83f822010-03-14 09:50:54 +00005107- Issue #7117: Backport round implementation from Python 3.x. ``round()`` now
5108 uses the correctly-rounded string <-> float conversions described above (when
5109 available), and so produces correctly rounded results that will display nicely
5110 under the float repr. There are two related small changes: (1) round now
5111 accepts any class with an ``__index__()`` method for its second argument (but
5112 no longer accepts floats for the second argument), and (2) an excessively
5113 large second integer argument (e.g., ``round(1.234, 10**100)``) no longer
5114 raises an exception.

Georg Brandlba83f822010-03-14 09:50:54 +00005257 (1) inf and nan strings with trailing whitespace were incorrectly rejected;
5258 (2) parsing of strings representing infinities and nans was locale aware; and
5259 (3) the interpretation of fromhex('-nan') didn't match that of float('-nan').

Georg Brandlba83f822010-03-14 09:50:54 +00005261- Issue #5920: For ``float.__format__()``, change the behavior with the empty
5262 presentation type (that is, not one of 'e', 'f', 'g', or 'n') to be like 'g'
5263 but with at least one decimal point and with a default precision
5264 of 12. Previously, the behavior the same but with a default precision of 6.
5265 This more closely matches ``str()``, and reduces surprises when adding
5266 alignment flags to the empty presentation type. This also affects the new
5267 complex.__format__ in the same way.
5268
5269- Issue #5890: In subclasses of 'property' the __doc__ attribute was shadowed by

Georg Brandlba83f822010-03-14 09:50:54 +00005450- Issue #4445: Replace ``sizeof(PyStringObject)`` with
5451 ``offsetof(PyStringObject, ob_sval) + 1`` when allocating memory for str
5452 instances. On a typical machine this saves 3 bytes of memory (on average) per
5453 string allocation.

Amaury Forgeot d'Arcdc619012008-11-22 20:01:18 +00005455- Issue #3996: On Windows, the PyOS_CheckStack function would cause the

Georg Brandlba83f822010-03-14 09:50:54 +00005459- Issue #3689: The list reversed iterator now supports __length_hint__ instead

5464
Georg Brandlba83f822010-03-14 09:50:54 +00005465- Issue #4233: Changed semantic of ``_fileio.FileIO``'s ``close()`` method on
5466 file objects with closefd=False. The file descriptor is still kept open but
5467 the file object behaves like a closed file. The ``FileIO`` object also got a
5468 new readonly attribute ``closefd``.

Georg Brandlba83f822010-03-14 09:50:54 +00005491- On windows, ``os.chdir()`` given unicode was not working if
5492 GetCurrentDirectoryW returned a path longer than MAX_PATH. (But It's doubtful
5493 this code path is really executed because I cannot move to such directory on
5494 win2k)

Georg Brandlba83f822010-03-14 09:50:54 +00005496- Issue #4069: When ``set.remove(element)`` is used with a set element, the
5497 element is temporarily replaced with an equivalent frozenset. But the
5498 eventual KeyError would always report the empty ``frozenset()`` as the missing
5499 key. Now it correctly refers to the initial element.

Walter Dörwalded960ac2009-05-03 22:36:33 +00005519- Issue #5108: Handle %s like %S and %R in PyUnicode_FromFormatV(): Call
5520 PyUnicode_DecodeUTF8() once, remember the result and output it in a second
5521 step. This avoids problems with counting UTF-8 bytes that ignores the effect
5522 of using the replace error handler in PyUnicode_DecodeUTF8().
5523
Walter Dörwald726ba8e2009-05-06 14:32:35 +00005524- Issue #3739: The unicode-internal encoder now reports the number of characters

5526
Georg Brandlba83f822010-03-14 09:50:54 +00005527- Issue #2422: When compiled with the ``--with-valgrind`` option, the pymalloc
5528 allocator will be automatically disabled when running under Valgrind. This
5529 gives improved memory leak detection when running under Valgrind, while taking
5530 advantage of pymalloc at other times.

6899
Amaury Forgeot d'Arc05e34492008-09-10 22:04:45 +00006900- Issue #3743: In a few places, PY_FORMAT_SIZE_T was incorrectly used with
6901 PyString_FromFormat or PyErr_Format to display size_t values. The macro
6902 PY_FORMAT_SIZE_T is designed to select the correct format for the OS
6903 ``printf`` function, whereas PyString_FromFormat has an independent
6904 implementation and uses "%zd" on all platforms for size_t values.
6905 This makes a difference on win64, where ``printf`` needs "%Id" to display
6906 64bit values.
6907
Benjamin Peterson97179b02008-09-09 20:55:01 +00006908- Issue #3634: _weakref.ref(Exception).__init__() gave invalid return value on

6912 object; previously an int would be returned for small values. the __long__
6913 method is allowed to return either an int or a long, but the behaviour of
6914 float objects should not change to respect backward compatibility.

Amaury Forgeot d'Arc3571fbf2008-09-01 19:52:00 +00006916- Issue #3751: str.rpartition would perform a left-partition when called with

Vinay Sajip35e3b032008-09-01 14:33:59 +00006922 PyArg_ParseTuple and friends, which occurred when the argument for "s*"
Antoine Pitroud4ae97b2008-08-29 18:39:48 +00006923 was correctly parsed but parsing of subsequent arguments failed.
6924
Vinay Sajip35e3b032008-09-01 14:33:59 +00006925- Issue #2534: speed up isinstance() and issubclass() by 50-70%, so as to
Antoine Pitrou0668c622008-08-26 22:42:08 +00006926 match Python 2.5 speed despite the __instancecheck__ / __subclasscheck__
6927 mechanism. In the process, fix a bug where isinstance() and issubclass(),
6928 when given a tuple of classes as second argument, were looking up
6929 __instancecheck__ / __subclasscheck__ on the tuple rather than on each
6930 type object.
6931

7075-----------------
7076
Guido van Rossumf8402962008-08-20 15:01:50 +00007077- Issue #1878: Remove Py_TPFLAGS_HAVE_VERSION_TAG from
7078 Py_TPFLAGS_DEFAULT when not building the core. This means 3rd party
7079 extensions do not automatically benefit from the class attribute
7080 cache; they will have to explicitly add Py_TPFLAGS_HAVE_VERSION_TAG
7081 to their tp_flags field if they care. This is a backwards
7082 compatibility feature; in 3.0, all types will use the cache by
7083 default.
7084
Benjamin Petersonf647dc12008-08-20 01:27:30 +00007085- Keyword arguments can now follow starred arguments. (``f(a, *args,
7086 keyword=23)`` is now valid syntax.)
7087
Thomas Heller0ad5ae02008-08-19 19:25:04 +00007088- ctypes function pointers that are COM methods have a boolean True
7089 value again.

7100
Amaury Forgeot d'Arc39fd6722008-07-31 21:28:03 +00007101- Issue #3479: On platforms where sizeof(int) is smaller than sizeof(long)
7102 (64bit Unix, for example), unichr() would truncate its argument and return
7103 u'\x00' for unichr(2**32). Now it properly raises an OverflowError.
7104
Neal Norwitze7d8be82008-07-31 17:17:14 +00007105- Apply security patches from Apple.
7106
Amaury Forgeot d'Arc246daed2008-07-31 00:42:16 +00007107- Issue #2542: Now that issubclass() may call arbitrary code, ensure that

Antoine Pitrou92f82162008-07-25 22:22:08 +00007110- Issue #1819: function calls with several named parameters are now on
7111 average 35% faster (as measured by pybench).
7112
Amaury Forgeot d'Arce4921fe2008-07-21 22:00:38 +00007113- Issue #2378: An unexpected UnboundLocalError or NameError could appear when
7114 the python debugger steps into a class statement: the free variables (local
7115 variables defined in an outer scope) would be deleted from the outer scope.
7116
Gregory P. Smith0470bab2008-07-22 04:46:32 +00007117- Issue #2620: Overflow checking when allocating or reallocating memory
7118 was not always being done properly in some python types and extension
7119 modules. PyMem_MALLOC, PyMem_REALLOC, PyMem_NEW and PyMem_RESIZE have
7120 all been updated to perform better checks and places in the code that
7121 would previously leak memory on the error path when such an allocation
7122 failed have been fixed.

7128
Benjamin Petersone977ad42008-08-20 01:42:01 +00007129- The methods ``is_in_tuple()``, ``is_vararg()``, and ``is_keywordarg()`` of
7130 symtable.Symbol have been deprecated for removal in 3.0 and the next release.
7131
Amaury Forgeot d'Arc351ffb82008-08-18 19:23:47 +00007132- Issue #2234: distutils failed for some versions of the cygwin compiler. The
7133 version reported by these tools does not necessarily follow the python
7134 version numbering scheme, so the module is less strict when parsing it.
7135
Nick Coghlanf70385a2008-08-18 12:42:46 +00007136- Issue #2235: Added Py3k warnings for types which will become unhashable
7137 under the stricter __hash__ inheritance rules in 3.0. Several types
7138 which did not meet the rules for hash invariants and were already
7139 unhashable in 3.0 have now been explicitly flagged as unhashable in
7140 2.6 as well (collections.Mapping, collections.Set, unittest.TestSuite,
7141 xml.dom.minidom.NamedNodeMap, numbers.Number, UserList.UserList)
7142
Brett Cannon88f801d2008-08-18 00:46:22 +00007143- Update __all__ for cookielib, csv, os, urllib2, and weakref to include things
7144 imported into the module but exposed as part of the module's API.
7145

7165 after a 302 response in the case of not going through a proxy.
7166
Antoine Pitroub90a8be2008-08-15 21:03:21 +00007167- Issue #2676: in the email package, content-type parsing was hanging on
7168 pathological input because of quadratic or exponential behaviour of a
7169 regular expression.
7170
Antoine Pitrou11ec65d2008-08-14 21:04:30 +00007171- Issue #3476: binary buffered reading through the new "io" library is now
7172 thread-safe.
7173
Brett Cannonbf3157b2008-08-14 05:00:03 +00007174- Silence the DeprecationWarning of rfc822 when it is imported by mimetools
7175 since mimetools itself is deprecated. Because modules are cached, all
7176 subsequent imports of rfc822 will not raise a visible DeprecationWarning.
7177
Antoine Pitrou9fcd4b32008-08-11 17:21:36 +00007178- Issue #3134: shutil referenced undefined WindowsError symbol.

7181 menu entries were not deleted.
7182
Brett Cannon83e81842008-08-09 23:30:55 +00007183- Copied the implementation of reduce() to _functools.reduce() to have a

7185
Antoine Pitrou76b8bee2008-08-09 17:27:23 +00007186- Issue #3205: When iterating over a BZ2File fails allocating memory, raise
7187 a MemoryError rather than silently stop the iteration.
7188
Guido van Rossum59ce9012008-08-09 14:55:34 +00007189- Issue #3487: sre "bytecode" validator. Passing invalid "re-bytecode"
7190 to _sre.compile() will now be rejected. This should not affect anybody
7191 since the re.compile() function never generates invalid re-bytecode.
7192
Skip Montanaroa032bf42008-08-08 22:52:51 +00007193- Issue #3436: Make csv.DictReader's fieldnames attribute a property so that
7194 upon first access it can be automatically initialized from the csv file if
7195 it wasn't initialized during instantiation.
7196
Brett Cannon3aa2a492008-08-06 22:28:09 +00007197- Issue #2338: Create imp.reload() to help with transitioning to Python 3.0 as
7198 the reload() built-in has been removed.
7199
Brett Cannon7e30b672008-08-04 21:52:25 +00007200- Changed code in the following modules/packages to remove warnings raised
Brett Cannonc1b76e42008-08-09 23:06:16 +00007201 while running under the ``-3`` flag: aifc, asynchat, asyncore, bdb, bsddb,

7209 raised an AttributeError.
7210
Benjamin Peterson01a24322008-07-28 23:35:27 +00007211- Issue #2523: Fix quadratic behaviour when read()ing a binary file without
Antoine Pitroude781a42008-08-09 12:43:23 +00007212 asking for a specific length. This problem only affected files opened
7213 using the new "io" module, not the built-in open() function.
Benjamin Peterson01a24322008-07-28 23:35:27 +00007214

Antoine Pitrou5fdfa3e2008-07-25 19:42:26 +00007238- Issue #3394: zipfile.writestr sets external attributes when passed a
7239 file name rather than a ZipInfo instance, so files are extracted with
7240 mode 0600 rather than 000 under Unix.
7241
Gregory P. Smitha36f8fe2008-08-04 00:13:29 +00007242- Issue #1857: subprocess.Popen.poll gained an additional _deadstate keyword
7243 argument in python 2.5, this broke code that subclassed Popen to include its
7244 own poll method. Fixed my moving _deadstate to an _internal_poll method.

Nick Coghlan6e8fef02008-08-18 13:14:22 +00007254- Issue #2235: the C API function PyObject_HashNotImplemented and its
7255 interaction with the tp_hash slot (added in 2.6b2) are now documented
7256
Nick Coghlan2a0c2b12008-08-04 12:47:17 +00007257- Issue #643841: The language reference now provides more detailed
7258 coverage of the lookup process for special methods. The disclaimers
7259 regarding lack of coverage of new-style classes have also been
7260 removed, since the coverage is now fairly reasonable.

7264================================
7265
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00007266*Release date: 17-Jul-2008*
7267
Raymond Hettingere3ae6552008-06-20 04:18:15 +00007268Core and Builtins
7269-----------------
7270
Georg Brandl3e483f62008-07-16 22:57:41 +00007271- Issue #3156: Fix inconsistent behavior of the bytearray type: all
7272 its methods now allow for items objects that can be converted to
7273 an integer using operator.index().
7274
Mark Dickinson64b7e502008-07-16 09:40:03 +00007275- Issue #3360: Fix incorrect parsing of '020000000000.0', which
7276 produced a ValueError instead of giving the correct float.
7277
Eric Smitha5fa5a22008-07-16 00:11:49 +00007278- Issue #3083: Add alternate (#) formatting for bin, oct, hex output
7279 for str.format(). This adds the prefix 0b, 0o, or 0x, respectively.
7280
Mark Dickinson7103aa42008-07-15 19:08:33 +00007281- Issue #3008: the float type has a new instance method 'float.hex'
7282 and a new class method 'float.fromhex' to convert floating-point
7283 numbers to and from hexadecimal strings, respectively.
7284
Nick Coghlan6d6bd442008-07-15 15:40:22 +00007285- Issue #2235: __hash__ is once again inherited by default. To allow
7286 collections.Hashable to remain meaningful in the presence of the
7287 default hash implementation (object.__hash__), it is now possible
7288 to explicit block inheritance of hash by setting __hash__=None at
7289 the Python level, or tp_hash=PyObject_HashNotImplemented at the C
7290 level.
7291
Nick Coghlanb028f502008-07-13 14:52:36 +00007292- Issue #3221: Issue a RuntimeWarning instead of raising SystemError if
7293 the parent module cannot be found while performing an absolute import.
7294 This means that an incorrectly defined __package__ attribute will
7295 now only prevent relative imports in that module rather than causing
7296 all imports from that module to fail.
7297
Nick Coghlan14ff9942008-07-08 14:21:42 +00007298- Issue #2517: Allow unicode messages in Exceptions again by correctly
7299 bypassing the instance dictionary when looking up __unicode__ on
7300 new-style classes.
7301
Amaury Forgeot d'Arcbdd941f2008-07-01 20:38:04 +00007302- Issue #3242: Fix a crash inside the print statement, if sys.stdout is
7303 set to a custom object whose write() method happens to install
7304 another file in sys.stdout.
7305
Amaury Forgeot d'Arc1f40c8a2008-06-30 22:42:40 +00007306- Issue #3088: Corrected a race condition in classes derived from
7307 threading.local: the first member set by a thread could be saved in
7308 another thread's dictionary.
7309
Mark Dickinson1ec2fcd2008-06-20 14:53:43 +00007310- Issue #3004: Minor change to slice.indices(): the start and stop
7311 arguments are now treated identically, making the behaviour easier
7312 to describe and understand. For example, slice(None, -10,
7313 1).indices(9) now returns (0, 0, 1) instead of (0, -1, 1), and
7314 slice(None, 10, -1).indices(10) returns (9, 9, -1) instead of (9,
7315 10, -1).
7316
Georg Brandl278fc502008-07-19 12:46:12 +00007317- Issue #3219: Calling a function with repeated keyword arguments,
7318 f(a=2, a=23), would not cause a syntax error. This was a regression
7319 from 2.4 caused by the switch to the new compiler.
Benjamin Peterson175e4d92008-07-01 19:34:52 +00007320
Georg Brandl278fc502008-07-19 12:46:12 +00007321- Issue #2862: Make int and float freelist management consistent with
7322 other freelists. Changes their CompactFreeList apis into
7323 ClearFreeList apis and calls them via gc.collect().
Gregory P. Smith2fe77062008-07-06 03:35:58 +00007324

7326-------
7327
Thomas Heller57adf222008-08-14 19:10:48 +00007328- Issue #3554: ctypes.string_at and ctypes.wstring_at did call Python
7329 api functions without holding the GIL, which could lead to a fatal
7330 error when they failed.
7331
Martin v. Löwisaabf4042008-08-02 07:20:25 +00007332- Issue #799428: Fix Tkinter.Misc._nametowidget to unwrap Tcl command objects.

Jesse Noller13e9d582008-07-16 14:32:36 +00007340- Issue #3125: Remove copy_reg in multiprocessing and replace it with
7341 ForkingPickler.register() to resolve conflict with ctypes.
7342
Vinay Sajip51e65192008-07-18 09:01:10 +00007343- Issue #3090: Fixed ARCHFLAGS parsing on OS/X
Jesse Noller13e9d582008-07-16 14:32:36 +00007344
Thomas Heller880f5292008-07-15 19:39:38 +00007345- Issue #3313: Fixed a crash when a failed dlopen() call does not set
7346 a valid dlerror() message.
7347
Thomas Heller2bad6572008-07-15 17:19:50 +00007348- Issue #3258: Fixed a crash when a ctypes POINTER type to an
7349 incomplete structure was created.
7350

7354
Andrew M. Kuchlingcc3f2b12008-07-10 14:43:31 +00007355- Issue #3301: Bisect module behaved badly when lo was negative.
Raymond Hettinger3cd1e422008-07-10 14:03:19 +00007356
Amaury Forgeot d'Arc0f7cddc2008-07-06 21:34:39 +00007357- Issue #839496: SimpleHTTPServer used to open text files in text mode. This is
7358 both unnecessary (HTTP allows text content to be sent in several forms) and
Andrew M. Kuchlingcc3f2b12008-07-10 14:43:31 +00007359 wrong because the actual transmitted size could differ from the
Amaury Forgeot d'Arc0f7cddc2008-07-06 21:34:39 +00007360 content-length. The problem had been corrected in the 2.4 branch, but never
7361 merged into trunk.
7362
Georg Brandle78fbcc2008-07-05 10:13:36 +00007363- Issue #2663: add filtering capability to shutil.copytree().

7369- Issue #1746: Correct handling of zipfile archive comments (previously
7370 archives with comments over 4k were flagged as invalid). Allow writing
Vinay Sajip51e65192008-07-18 09:01:10 +00007371 Zip files with archives by setting the 'comment' attribute of a ZipFile.
Martin v. Löwis8c436412008-07-03 12:51:14 +00007372
Vinay Sajip51e65192008-07-18 09:01:10 +00007373- Issue #449227: The rlcompleter module now adds "(" to callable objects
Andrew M. Kuchlingcc3f2b12008-07-10 14:43:31 +00007374 when completed.
Facundo Batista66c52772008-07-02 16:52:55 +00007375
Nick Coghlanc060b0e2008-07-02 13:09:19 +00007376- Issue #3190: Pydoc now hides the automatic module attribute __package__ (the
7377 handling is now the same as that of other special attributes like __name__).
7378
Brett Cannon8bb8fa52008-07-02 01:57:08 +00007379- Issue #2885 (partial): The urllib.urlopen() function has been deprecated for
7380 removal in Python 3.0 in favor of urllib2.urlopen().

Georg Brandl5cc774e2008-06-11 20:28:06 +00007767 PPC64 and x86_64 support in one binary).
Ronald Oussoren5640ce22008-06-05 12:58:24 +00007768
7769 This is controlled by the configure argument ``--with-universal-archs``:
7770
7771 - ``--with-universal-archs=all``: install 4-way universal
7772
7773 - ``--with-universal-archs=32-bit``: install 2-way universal, 32-bit (the default)
7774
7775 - ``--with-universal-archs=64-bit``: install 2-way universal, 64-bit
7776
7777 This option should be used in combination with ``--enable-universalsdk=``.
7778
7779 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 +00007828- Issue #1631171: Re-implement the 'warnings' module in C (the
7829 original Python code has been kept as backup). This will allow for
7830 using the 'warning's machinery in such places as the parser where
7831 use of pure Python code is not possible. Both the ``showarning()``
7832 and ``formatwarning()`` gain an optional 'line' argument which is
7833 not called by default for backwards-compatibility reasons. Setting
7834 ``warnings.showwarning()`` to an implementation that lacks support
7835 for the ``line`` argument will raise a DeprecationWarning.

Georg Brandl3ee81df2008-05-17 18:14:43 +00007898- Issue #2550: The approach used by client/server code for obtaining
7899 ports to listen on in network-oriented tests has been refined in an
7900 effort to facilitate running multiple instances of the entire
7901 regression test suite in parallel without issue.
7902 test_support.bind_port() has been fixed such that it will always
7903 return a unique port -- which wasn't always the case with the
7904 previous implementation, especially if socket options had been set
7905 that affected address reuse (i.e. SO_REUSEADDR, SO_REUSEPORT). The
7906 new implementation of bind_port() will actually raise an exception
7907 if it is passed an AF_INET/SOCK_STREAM socket with either the
7908 SO_REUSEADDR or SO_REUSEPORT socket option set. Furthermore, if
7909 available, bind_port() will set the SO_EXCLUSIVEADDRUSE option on
7910 the socket it's been passed. This currently only applies to
7911 Windows. This option prevents any other sockets from binding to the
7912 host/port we've bound to, thus removing the possibility of the
7913 'non-deterministic' behaviour, as Microsoft puts it, that occurs
7914 when a second SOCK_STREAM socket binds and accepts to a host/port
7915 that's already been bound by another socket. The optional preferred
7916 port parameter to bind_port() has been removed. Under no
7917 circumstances should tests be hard coding ports!
7918
7919 test_support.find_unused_port() has also been introduced, which will
7920 pass a temporary socket object to bind_port() in order to obtain an
7921 unused port. The temporary socket object is then closed and
7922 deleted, and the port is returned. This method should only be used
7923 for obtaining an unused port in order to pass to an external program
7924 (i.e. the -accept [port] argument to openssl's s_server mode) or as
7925 a parameter to a server-oriented class that doesn't give you direct
7926 access to the underlying socket used.
7927
7928 Finally, test_support.HOST has been introduced, which should be used
7929 for the host argument of any relevant socket calls (i.e. bind and
7930 connect).
Trent Nelsone41b0062008-04-08 23:47:30 +00007931
7932 The following tests were updated to following the new conventions:
Georg Brandl3ee81df2008-05-17 18:14:43 +00007933 test_socket, test_smtplib, test_asyncore, test_ssl, test_httplib,
Trent Nelsone41b0062008-04-08 23:47:30 +00007934 test_poplib, test_ftplib, test_telnetlib, test_socketserver,
7935 test_asynchat and test_socket_ssl.
7936
Georg Brandl3ee81df2008-05-17 18:14:43 +00007937 It is now possible for multiple instances of the regression test
7938 suite to run in parallel without issue.

Fred Drakea8ee94b2008-03-01 02:45:07 +00008207- Issue #2051: pyc and pyo files are no longer created with permission
Barry Warsaw52973612008-03-01 02:23:38 +00008208 644. The mode is now inherited from the py file.
Christian Heimes40346852008-02-23 17:52:07 +00008209
Georg Brandlad61bc82008-02-23 15:11:18 +00008210- Issue #2067: file.__exit__() now calls subclasses' close() method.
8211
8212- Patch #1759: Backport of PEP 3129 class decorators.
Christian Heimes5224d282008-02-23 15:01:05 +00008213
Vinay Sajipb7edfc42008-04-02 21:10:23 +00008214- Issue #1881: An internal parser limit has been increased. Also see
Georg Brandl222e2082010-08-01 22:27:39 +00008215 issue #215555 for a discussion.
Facundo Batistafc2d0102008-02-23 12:01:13 +00008216
Eric Smitha73fbe72008-02-23 03:09:44 +00008217- Added the future_builtins module, which contains hex() and oct().
8218 These are the PEP 3127 version of these functions, designed to be
8219 compatible with the hex() and oct() builtins from Python 3.0. They
8220 differ slightly in their output formats from the existing, unchanged
8221 Python 2.6 builtins. The expected usage of the future_builtins
8222 module is:
8223 from future_builtins import hex, oct
8224
Eric Smith7ef40bf2008-02-20 23:34:22 +00008225- Issue #1600: Modifed PyOS_ascii_formatd to use at most 2 digit
8226 exponents for exponents with absolute value < 100. Follows C99
8227 standard. This is a change on Windows, which would use 3 digits.
8228 Also, added 'n' to the formats that PyOS_ascii_formatd understands,
8229 so that any alterations it does to the resulting string will be
8230 available in stringlib/formatter.h (for float.__format__).
8231
Eric Smith5a3c1352008-02-19 13:21:56 +00008232- Implemented PEP 3101, Advanced String Formatting. This adds a new
8233 builtin format(); a format() method for str and unicode; a
8234 __format__() method to object, str, unicode, int, long, float, and
8235 datetime; the class string.Formatter; and the C API
8236 PyObject_Format().
8237
Georg Brandl3ee81df2008-05-17 18:14:43 +00008238- Fixed several potential crashes, all caused by specially crafted
8239 __del__ methods exploiting objects in temporarily inconsistent
8240 state.
Amaury Forgeot d'Arc632fad32008-02-16 20:55:24 +00008241
Vinay Sajipb7edfc42008-04-02 21:10:23 +00008242- Issue #2115: Important speedup in setting __slot__ attributes. Also
Georg Brandl3ee81df2008-05-17 18:14:43 +00008243 prevent a possible crash: an Abstract Base Class would try to access
8244 a slot on a registered virtual subclass.
Amaury Forgeot d'Arc60d6c7f2008-02-15 21:22:45 +00008245
Georg Brandl3ee81df2008-05-17 18:14:43 +00008246- Fixed repr() and str() of complex numbers with infinity or nan as
8247 real or imaginary part.
Christian Heimes2f0da532008-02-15 06:57:08 +00008248
Georg Brandl3ee81df2008-05-17 18:14:43 +00008249- Clear all free lists during a gc.collect() of the highest generation
8250 in order to allow pymalloc to free more arenas. Python may give back
8251 memory to the OS earlier.
Christian Heimes3b718a72008-02-14 12:47:33 +00008252
Georg Brandl3ee81df2008-05-17 18:14:43 +00008253- Issue #2045: Fix an infinite recursion triggered when printing a
8254 subclass of collections.defaultdict, if its default_factory is set
8255 to a bound method.
Amaury Forgeot d'Arcb01aa432008-02-08 00:56:02 +00008256
Christian Heimesf75dbef2008-02-08 00:11:31 +00008257- Fixed a minor memory leak in dictobject.c. The content of the free
8258 list was not freed on interpreter shutdown.
8259
Georg Brandl21e99f42010-03-07 15:23:59 +00008260- Limit free list of method and built-in function objects to 256
Georg Brandl3ee81df2008-05-17 18:14:43 +00008261 entries each.
Christian Heimes6075a822008-02-06 12:44:34 +00008262
Georg Brandl3ee81df2008-05-17 18:14:43 +00008263- Patch #1953: Added ``sys._compact_freelists()`` and the C API
8264 functions ``PyInt_CompactFreeList`` and ``PyFloat_CompactFreeList``
Christian Heimes422051a2008-02-04 18:00:12 +00008265 to compact the internal free lists of pre-allocted ints and floats.
8266
Georg Brandl3ee81df2008-05-17 18:14:43 +00008267- Issue #1983: Fixed return type of fork(), fork1() and forkpty()
8268 calls. Python expected the return type int but the fork familie
8269 returns pi_t.
Christian Heimes951cc0f2008-01-31 23:08:23 +00008270
Georg Brandl3ee81df2008-05-17 18:14:43 +00008271- Issue #1678380: Fix a bug that identifies 0j and -0j when they
8272 appear in the same code unit.
Mark Dickinson105be772008-01-31 22:17:37 +00008273
Georg Brandl3ee81df2008-05-17 18:14:43 +00008274- Issue #2025: Add tuple.count() and tuple.index() methods to comply
8275 with the collections.Sequence API.
Raymond Hettinger5b07ebc2008-02-07 00:54:20 +00008276
Georg Brandl3ee81df2008-05-17 18:14:43 +00008277- Patch #1970 by Antoine Pitrou: Speedup unicode whitespace and
8278 linebreak detection
Christian Heimes4d4f2702008-01-30 11:32:37 +00008279
Georg Brandl3ee81df2008-05-17 18:14:43 +00008280- Added ``PyType_ClearCache()`` and ``sys._clear_type_cache`` to clear
8281 the internal lookup cache for ref leak tests.
Christian Heimes908caac2008-01-27 23:34:59 +00008282
Georg Brandl3ee81df2008-05-17 18:14:43 +00008283- Patch #1473257: generator objects gain a gi_code attribute. This is
8284 the same object as the func_code attribute of the function that
8285 produced the generator.
Georg Brandl0cdf9a32008-01-26 14:14:20 +00008286
Georg Brandl3ee81df2008-05-17 18:14:43 +00008287- Issue #1920: "while 0" statements were completely removed by the
8288 compiler, even in the presence of an "else" clause, which is
8289 supposed to be run when the condition is false. Now the compiler
8290 correctly emits bytecode for the "else" suite.
Amaury Forgeot d'Arc31eaafe2008-01-24 22:59:25 +00008291
Guido van Rossumeead05f2008-01-24 18:21:02 +00008292- A few crashers fixed: weakref_in_del.py (issue #1377858);
8293 loosing_dict_ref.py (issue #1303614, test67.py);
8294 borrowed_ref_[34].py (not in tracker).
8295
Vinay Sajipd7cf32e2008-01-24 12:43:33 +00008296- Issue #1069410: The "can't load dll" message box on Windows is
Christian Heimesb2302ba2008-01-23 17:15:06 +00008297 suppressed while an extension is loaded by calling SetErrorMode in
8298 dynload_win.c. The error is still reported properly.
8299
Georg Brandl3ee81df2008-05-17 18:14:43 +00008300- Issue #1915: Python compiles with --enable-unicode=no again. However
Christian Heimes082c9b02008-01-23 14:20:50 +00008301 several extension methods and modules do not work without unicode
8302 support.
8303
Georg Brandl26543b12008-01-21 18:36:51 +00008304- Issue #1882: when compiling code from a string, encoding cookies in the
8305 second line of code were not always recognized correctly.
8306
Georg Brandl14404b62008-01-19 19:27:05 +00008307- Issue #1679: "0x" was taken as a valid integer literal.
8308
Georg Brandl6caad7d2008-01-26 14:19:22 +00008309- Issue #1865: ``bytes`` as an alias for ``str`` and b"" as an alias "" were
Christian Heimes288e89a2008-01-18 18:24:07 +00008310 added.
8311
Christian Heimesc94e2b52008-01-14 04:13:37 +00008312- sys.float_info / PyFloat_GetInfo: The floating point information
8313 object was converted from a dict to a specialized structseq object.
8314
Georg Brandl3ee81df2008-05-17 18:14:43 +00008315- Patch #1816: Added sys.flags structseq. It exposes the status of
8316 most command line arguments and PYTHON* environment variables.
Christian Heimesf31b69f2008-01-14 03:42:48 +00008317
Georg Brandl3ee81df2008-05-17 18:14:43 +00008318- Objects/structseq.c: Implemented new structseq representation. The
8319 patch makes structseqs (e.g. the return value of os.stat) more
8320 readable.
Christian Heimes9c201962008-01-14 03:33:52 +00008321
Georg Brandl3ee81df2008-05-17 18:14:43 +00008322- Patch #1700288: added a type attribute cache that caches method
8323 accesses, resulting in speedups in heavily object-oriented code.
Amaury Forgeot d'Arce4c270c2008-01-14 00:29:41 +00008324
Neal Norwitz3fc15b82008-01-10 05:42:58 +00008325- Bug #1776: __import__() no longer accepts filenames on any platform.
8326 The first parameter to __import__() must be a valid module name.
Christian Heimes3403f152008-01-09 19:56:33 +00008327
Georg Brandlaed6c662008-01-07 17:25:53 +00008328- Patch #1668: renamed THREADDEBUG envvar to PYTHONTHREADDEBUG.
8329
Georg Brandl3ee81df2008-05-17 18:14:43 +00008330- Patch #602345: Add -B command line option, PYTHONDONTWRITEBYTECODE
8331 envvar and sys.dont_write_bytecode attribute. All these can be set
8332 to forbid Python to attempt to write compiled bytecode files.
Georg Brandl2da0fce2008-01-07 17:09:35 +00008333
Georg Brandl3ee81df2008-05-17 18:14:43 +00008334- Improve some exception messages when Windows fails to load an
8335 extension module. Now we get for example '%1 is not a valid Win32
8336 application' instead of 'error code 193'.
Amaury Forgeot d'Arce0b76952008-01-04 02:04:15 +00008337
Georg Brandl3ee81df2008-05-17 18:14:43 +00008338- Bug #1481296: Fixed long(float('nan')) != 0L.

Georg Brandl3ee81df2008-05-17 18:14:43 +00008340- Issue #1640: Added math.isinf(x), math.isnan(x) and math.copysign(x,
8341 y) functions.
Christian Heimese2ca4242008-01-03 20:23:15 +00008342
Christian Heimes0a8143f2007-12-18 23:22:54 +00008343- Issue #1635: Platform independent creation and representation of NaN
Georg Brandl3ee81df2008-05-17 18:14:43 +00008344 and INF. float("nan"), float("inf") and float("-inf") now work on
8345 every platform with IEEE 754 semantics.
Christian Heimes0a8143f2007-12-18 23:22:54 +00008346
Georg Brandl3ee81df2008-05-17 18:14:43 +00008347- Compiler now generates simpler and faster code for dictionary
8348 literals. The oparg for BUILD_MAP now indicates an estimated
8349 dictionary size. There is a new opcode, STORE_MAP, for adding
8350 entries to the dictionary.
Raymond Hettingerfd7ed402007-12-18 21:24:09 +00008351
Georg Brandl3ee81df2008-05-17 18:14:43 +00008352- Issue #1638: %zd configure test fails on Linux.

Georg Brandl3ee81df2008-05-17 18:14:43 +00008357- Issue #1538: Avoid copying string in split/rsplit if the split char
8358 is not found.
Skip Montanaro26015492007-12-08 15:33:24 +00008359
Andrew M. Kuchling395fe442007-12-05 13:27:20 +00008360- Issue #1553: An erroneous __length_hint__ can make list() raise a
Christian Heimes7cc1c6f2007-12-05 12:52:34 +00008361 SystemError.
8362
Nick Coghlanef01d822007-12-03 12:55:17 +00008363- PEP 366: Allow explicit relative imports when executing modules
8364 inside packages with the -m switch via a new module level
8365 __package__ attribute.
8366
Georg Brandl3ee81df2008-05-17 18:14:43 +00008367- Issue #1402: Fix a crash on exit, when another thread is still
8368 running, and if the deallocation of its frames somehow calls the
8369 PyGILState_Ensure() / PyGILState_Release() functions.
Amaury Forgeot d'Arcbe49a902007-11-30 20:37:22 +00008370

Amaury Forgeot d'Arcce7d10c2007-11-24 13:44:17 +00008374 attribute of an empty cell object.
8375
Georg Brandl3ee81df2008-05-17 18:14:43 +00008376- Issue #1460: The utf-7 incremental decoder did not accept truncated
8377 input. It now correctly saves its state between chunks of data.
Amaury Forgeot d'Arcf57375a2007-11-21 01:38:26 +00008378
Georg Brandl3ee81df2008-05-17 18:14:43 +00008379- Patch #1739468: Directories and zipfiles containing a __main__.py
8380 file can now be directly executed by passing their name to the
8381 interpreter. The directory/zipfile is automatically inserted as the
8382 first entry in sys.path.
Nick Coghlan327a39b2007-11-18 11:56:28 +00008383
Georg Brandl3ee81df2008-05-17 18:14:43 +00008384- Issue #1265: Fix a problem with sys.settrace, if the tracing
8385 function uses a generator expression when at the same time the
8386 executed code is closing a paused generator.
Amaury Forgeot d'Arc0d75f092007-11-13 21:54:28 +00008387
Raymond Hettinger1760c8a2007-11-08 02:52:43 +00008388- sets and frozensets now have an isdisjoint() method.
8389
Raymond Hettinger3f8caa32007-10-24 01:28:33 +00008390- optimize the performance of builtin.sum().
8391
Neal Norwitz44f326e2007-10-05 05:29:17 +00008392- Fix warnings found by the new version of the Coverity checker.
8393
Georg Brandl21e99f42010-03-07 15:23:59 +00008394- The enumerate() built-in function is no longer bounded to sequences
Georg Brandl3ee81df2008-05-17 18:14:43 +00008395 smaller than LONG_MAX. Formerly, it raised an OverflowError. Now,
8396 automatically shifts from ints to longs.
Raymond Hettinger8f669372007-10-03 21:18:11 +00008397
Georg Brandl3ee81df2008-05-17 18:14:43 +00008398- Issue #1686386: Tuple's tp_repr did not take into account the
8399 possibility of having a self-referential tuple, which is possible
8400 from C code. Nor did object's tp_str consider that a type's tp_str
8401 could do something that could lead to an inifinite recursion.
8402 Py_ReprEnter() and Py_EnterRecursiveCall(), respectively, fixed the
8403 issues.
Brett Cannon0b14f242007-09-30 19:45:10 +00008404
Georg Brandl3ee81df2008-05-17 18:14:43 +00008405- Issue #1164: It was possible to trigger deadlock when using the
8406 'print' statement to write to a file since the GIL was not released
8407 as needed. Now PyObject_Print() does the right thing along with
8408 various tp_print implementations of the built-in types and those in
8409 the collections module.
Brett Cannon01531592007-09-17 03:28:34 +00008410
Georg Brandl3ee81df2008-05-17 18:14:43 +00008411- Issue #1147: Exceptions were directly allowing string exceptions in
8412 their throw() method even though string exceptions no longer
8413 allowed.
Brett Cannon4c20bc42007-09-11 21:02:28 +00008414
Georg Brandl3ee81df2008-05-17 18:14:43 +00008415- Issue #1096: Prevent a segfault from getting the repr of a very
8416 deeply nested list by using the recursion counter.

Brett Cannon1e534b52007-09-07 04:18:30 +00008418- Issue #1202533: Fix infinite recursion calls triggered by calls to
Georg Brandl3ee81df2008-05-17 18:14:43 +00008419 PyObject_Call() never calling back out to Python code to trigger
8420 recursion depth updates/checks. Required the creation of a static
8421 RuntimeError instance in case normalizing an exception put the
8422 recursion check value past its limit. Fixes crashers
8423 infinite_rec_(1|2|4|5).py.
Brett Cannon1e534b52007-09-07 04:18:30 +00008424
Georg Brandl3ee81df2008-05-17 18:14:43 +00008425- Patch #1031213: Decode source line in SyntaxErrors back to its

Neal Norwitz0ac60192007-05-27 04:08:54 +00008438- Add new attribute names for function objects. All the func_* become
Georg Brandl3ee81df2008-05-17 18:14:43 +00008439 __*__ attributes. (Some already existed, e.g., __doc__ and
8440 __name__.)
Neal Norwitz0ac60192007-05-27 04:08:54 +00008441
Neal Norwitz8b2bfbc2007-05-23 06:35:32 +00008442- Add -3 option to the interpreter to warn about features that are
8443 deprecated and will be changed/removed in Python 3.0.
8444

8446 calls.
8447
Collin Winter62903052007-05-18 23:11:24 +00008448- except clauses may now be spelled either "except E, target:" or
Georg Brandl3ee81df2008-05-17 18:14:43 +00008449 "except E as target:". This is to provide forwards compatibility
8450 with Python 3.0.
Collin Winter62903052007-05-18 23:11:24 +00008451
Brett Cannon229cee22007-05-05 01:34:02 +00008452- Deprecate BaseException.message as per PEP 352.
8453
Georg Brandl3ee81df2008-05-17 18:14:43 +00008454- Issue #1303614: don't expose object's __dict__ when the dict is
Georg Brandl21e99f42010-03-07 15:23:59 +00008455 inherited from a built-in base.
Armin Rigo9790a272007-05-02 19:23:31 +00008456
Vinay Sajip8549ce32007-05-06 17:53:37 +00008457- When __slots__ are set to a unicode string, make it work the same as
Neal Norwitzcbd9ee62007-04-14 05:25:50 +00008458 setting a plain string, ie don't expand to single letter identifiers.
8459
Raymond Hettinger13936692007-04-11 18:40:58 +00008460- Request #1191699: Slices can now be pickled.
8461
Raymond Hettinger4db5fe92007-04-12 04:10:00 +00008462- Request #1193128: str.translate() now allows a None argument for

8464 remaining characters.
8465
Georg Brandl5cb76c12007-03-21 09:00:39 +00008466- Patch #1682205: a TypeError while unpacking an iterable is no longer

8470
Guido van Rossum143b5642007-03-23 04:58:42 +00008471- Bug #1683368: The object.__init__() and object.__new__() methods are
8472 now stricter in rejecting excess arguments. The only time when
8473 either allows excess arguments is when it is not overridden and the
8474 other one is. For backwards compatibility, when both are
8475 overridden, it is a deprecation warning (for now; maybe a Py3k
Guido van Rossum234b1ff2007-03-23 19:39:01 +00008476 warning later). Also, type.__init__() insists on the same signature
8477 as supported by type.__new__().
Guido van Rossum143b5642007-03-23 04:58:42 +00008478
Georg Brandl3ee81df2008-05-17 18:14:43 +00008479- Patch #1675423: PyComplex_AsCComplex() now tries to convert an
8480 object to complex using its __complex__() method before falling back
8481 to the __float__() method. Therefore, the functions in the cmath
8482 module now can operate on objects that define a __complex__()
8483 method.

Georg Brandl7b9c5552007-03-12 14:30:05 +00008501- Bug #1678647: write a newline after printing an exception in any
8502 case, even when converting the value to a string failed.
8503
Georg Brandl871f1bc2007-03-12 13:17:36 +00008504- The dir() function has been extended to call the __dir__() method on
Georg Brandl3ee81df2008-05-17 18:14:43 +00008505 its argument, if it exists. If not, it will work like before. This
8506 allows customizing the output of dir() in the presence of a
8507 __getattr__().

8516 parthensized forms. This means complex(repr(x)) now works instead of
8517 raising a ValueError.
Collin Wintere38051d2007-03-09 20:33:07 +00008518
Georg Brandlaa2321b2007-03-07 00:40:28 +00008519- Patch #703779: unset __file__ in __main__ after running a file. This
Georg Brandl3ee81df2008-05-17 18:14:43 +00008520 makes the filenames the warning module prints much more sensible
8521 when a PYTHONSTARTUP file is used.
Georg Brandlaa2321b2007-03-07 00:40:28 +00008522

Georg Brandl0fca97a2007-03-05 22:28:08 +00008534- Patch #1674228: when assigning a slice (old-style), check for the
8535 sq_ass_slice instead of the sq_slice slot.
8536
Georg Brandl3ee81df2008-05-17 18:14:43 +00008537- When printing an unraisable error, don't print exceptions. before
8538 the name. This duplicates the behavior whening normally printing
8539 exceptions.

Georg Brandl2c1375c2006-10-12 11:27:59 +00008589- Bug #1545497: when given an explicit base, int() did ignore NULs
8590 embedded in the string to convert.
8591
Georg Brandl846f73a2006-10-08 07:11:54 +00008592- Bug #1569998: break inside a try statement (outside a loop) is now

Georg Brandl4e933132006-09-06 20:05:58 +00008622- Bug #1542051: Exceptions now correctly call PyObject_GC_UnTrack.

Georg Brandl3ee81df2008-05-17 18:14:43 +00008640 generator expressions (x for x, in ... ) works again. Fixing this

Georg Brandl3ee81df2008-05-17 18:14:43 +00009442- Issue #829951: In the smtplib module, SMTP.starttls() now complies
9443 with RFC 3207 and forgets any knowledge obtained from the server not
9444 obtained from the TLS negotiation itself. Patch contributed by Bill
9445 Fenner.
Gregory P. Smith2b3ba582008-01-17 08:03:17 +00009446
Georg Brandl3ee81df2008-05-17 18:14:43 +00009447- Issue #1339: The smtplib.SMTP class has been refactored a bit such
Gregory P. Smithbde4ae42008-01-17 08:35:49 +00009448 that the SMTP.starttls() caller no longer needs to call ehlo()
9449 beforehand. SMTP.starttls() now raises an exception of the server
Georg Brandl3ee81df2008-05-17 18:14:43 +00009450 does not claim to support starttls. Adds the
9451 SMTP.ehlo_or_helo_if_needed() method. Patch contributed by Bill

9521 contents before adding elements from the iterable. This fix brings
9522 the behavior into line with that for list.__init__().

9532 complex, tuple, list, dict, set, and frozenset. Formerly, it would
9533 silently miscode subclasses of those types. Now, it raises a
9534 ValueError instead.
Raymond Hettinger12e94202007-11-07 01:13:09 +00009535

Georg Brandl3ee81df2008-05-17 18:14:43 +00009550 time so that opening a database previously created with the DB_DUP
9551 or DB_DUPSORT flag set will keep the proper behavior on subsequent
9552 opens. Specifically: dictionary assignment to a DB object will
9553 replace all values for a given key when the database allows
9554 duplicate values. DB users should use DB.put(k, v) when they want
9555 to store duplicates; not DB[k] = v.
Gregory P. Smithec10a4a2007-11-05 02:32:26 +00009556

9562 characters with ASCII value less than 32. Also, it correctly quotes
9563 dots only if they occur on a single line, as opposed to the previous
9564 behavior of quoting dots if they are the second character of any
9565 line.
Georg Brandl4aef7272007-03-13 22:49:43 +00009566

Georg Brandl3ee81df2008-05-17 18:14:43 +00009915- Issue #1521: On 64bit platforms, using PyArgs_ParseTuple with the t#
9916 of w# format code incorrectly truncated the length to an int, even
9917 when PY_SSIZE_T_CLEAN is set. The str.decode method used to return
9918 incorrect results with huge strings.

9928 defined.
Georg Brandl6caad7d2008-01-26 14:19:22 +00009929
9930- Patch #1733960: Allow T_LONGLONG to accept ints.

9937
9938- Fix some leftovers from the conversion from int to Py_ssize_t
9939 (relevant to strings and sequences of more than 2**31 items).
9940
9941- Make _PyGILState_NoteThreadState() static, it was not used anywhere
9942 outside of pystate.c and should not be necessary.
9943
Georg Brandl3ee81df2008-05-17 18:14:43 +00009944- ``PyImport_Import`` and ``PyImport_ImportModule`` now always do
9945 absolute imports. In earlier versions they might have used relative
9946 imports under some conditions.
Christian Heimes000a0742008-01-03 22:16:32 +00009947
Georg Brandl3ee81df2008-05-17 18:14:43 +00009948- Added case insensitive comparison methods ``PyOS_stricmp(char*,
9949 char*)`` and ``PyOS_strnicmp(char*, char*, Py_ssize_t)``.
Christian Heimes000a0742008-01-03 22:16:32 +00009950
Georg Brandl3ee81df2008-05-17 18:14:43 +00009951- Bug #1542693: remove semi-colon at end of PyImport_ImportModuleEx

Georg Brandl3ee81df2008-05-17 18:14:43 +00009957- Patch #1706: Drop support for Win9x, WinME and NT4. Python now
9958 requires Windows 2000 or greater. The _WINVER and NTDDI_VERSION
9959 macros are set to Win2k for x86/32bit builds and WinXP for AMD64
9960 builds.

Georg Brandl3ee81df2008-05-17 18:14:43 +00009974- Removed the macfs module. It had been deprecated since Python 2.5.
9975 This lead to the deprecation of macostools.touched() as it relied
9976 solely on macfs and was a no-op under OS X.
