105Core and Builtins
106-----------------
107
Philip Jenveyaebbaeb2010-04-06 23:24:45 +0000108- Issue #7301: Add environment variable $PYTHONWARNINGS.
109
Benjamin Peterson3a1dfa22010-04-06 21:50:00 +0000110- Issue #8329: Don't return the same lists from select.select when no fds are
111 changed.

Mark Dickinson82791672010-04-06 16:47:55 +0000113- Issue #8259: 1L << (2**31) no longer produces an 'outrageous shift error'
114 on 64-bit machines. The shift count for either left or right shift is
115 permitted to be up to sys.maxsize.

124 is called with a non-empty format string. This is an effort to
125 future-proof user code. If a derived class does not currently
126 implement __format__ but later adds its own __format__, it would
127 most likely break user code that had supplied a format string. This
128 will be changed to a DeprecationWaring in Python 3.3 and it will be
129 an error in Python 3.4.

Georg Brandlba83f822010-03-14 09:50:54 +0000145 (SIGINT). If an error occurs while importing the site module, the error is
146 printed and Python exits. Initialize the GIL before importing the site
Victor Stinner66644262010-03-10 22:30:19 +0000147 module.

157 using the new attributes `ssl.OPENSSL_VERSION`, `ssl.OPENSSL_VERSION_INFO`

169
Raymond Hettingera551f312010-04-04 18:34:45 +0000170- the functools module now has a total_ordering() class decorator
Georg Brandl4fabac52010-04-14 08:53:38 +0000171 to simplify the specification of rich comparisons.

Mark Dickinsone096e822010-04-02 10:17:07 +0000179- Issue #7279: Comparisons involving a Decimal signaling NaN now
180 signal InvalidOperation instead of returning False. (Comparisons
Mark Dickinsonf3eeca12010-04-02 10:35:12 +0000181 involving a quiet NaN are unchanged.) Also, Decimal quiet NaNs
182 are now hashable; Decimal signaling NaNs remain unhashable.

190 argument `-` which tells it to read files to compile from stdin. Each line
191 is read on demand and the named file is compiled immediately. (Original
192 patch by Piotr Ożarowski).
193
194- Issue #3135: Add inspect.getcallargs, which binds arguments to a function
195 like a normal call.
Benjamin Peterson7e213252010-03-30 17:58:13 +0000196
Florent Xicluna58b65662010-03-30 16:29:03 +0000197- Backwards incompatible change: Unicode codepoints line tabulation (0x0B) and
198 form feed (0x0C) are now considered linebreaks, as specified in Unicode
199 Standard Annex #14. See issue #7643.

203 a Fractions instance now raise TypeError instead of returning
204 True/False. This makes Fraction <=> complex comparisons consistent with
205 int <=> complex, float <=> complex, and complex <=> complex comparisons.

Mark Dickinson4846a8e2010-04-03 14:05:10 +0000302- Issue #8300: When passing a non-integer argument to struct.pack with any
303 integer format code, struct.pack first attempts to convert the non-integer
304 using its __index__ method. If that method is non-existent or raises
305 TypeError it goes on to try the __int__ method, as described below.
306
Georg Brandlba83f822010-03-14 09:50:54 +0000307- Issue #1530559: When passing a non-integer argument to struct.pack with *any*
308 integer format code (one of 'bBhHiIlLqQ'), struct.pack attempts to use the
309 argument's __int__ method to convert to an integer before packing. It also
310 produces a DeprecationWarning in this case. (In Python 2.6, the behaviour
311 was inconsistent: __int__ was used for some integer codes but not for others,
312 and the set of integer codes for which it was used differed between native
313 packing and standard packing.)

709Core and Builtins
710-----------------
711
Georg Brandlba83f822010-03-14 09:50:54 +0000712- The ``__complex__()`` method is now looked up on the class of instances to
713 make it consistent with other special methods.

717
Mark Dickinson1b34d252010-01-01 17:27:30 +0000718- Issue #5080: A number of functions and methods previously produced a
Georg Brandlba83f822010-03-14 09:50:54 +0000719 DeprecationWarning when passed a float argument where an integer was expected.
720 These functions and methods now raise TypeError instead. The majority of the
721 effects of this change are in the extension modules, but some core functions
722 and methods are affected: notably the 'chr', 'range' and 'xrange' builtins,
723 and many unicode/str methods.

735
Georg Brandlba83f822010-03-14 09:50:54 +0000736- Issue #1811: Improve accuracy and cross-platform consistency for true division
737 of integers: the result of a/b is now correctly rounded for ints a and b (at
738 least on IEEE 754 platforms), and in particular does not depend on the
739 internal representation of a long.

747
Georg Brandlba83f822010-03-14 09:50:54 +0000748 These executables now work properly with the arch(1) command: ``arch -ppc
749 python`` will start a universal binary version of python in PPC mode (unlike
750 previous releases).

Georg Brandlba83f822010-03-14 09:50:54 +0000888- Issue #3382: 'F' formatting for float and complex now convert the result to
889 upper case. This only affects 'inf' and 'nan', since 'f' no longer converts
890 to 'g' for large values.
Amaury Forgeot d'Arcd7288712009-12-01 21:51:04 +0000891
Georg Brandlba83f822010-03-14 09:50:54 +0000892- Remove switch from "%f" formatting to "%g" formatting for floats larger than
893 1e50 in absolute value.
Mark Dickinson9dd5e162009-11-23 20:54:09 +0000894
Georg Brandlba83f822010-03-14 09:50:54 +0000895- Remove restrictions on precision when formatting floats. E.g., "%.120g" %
896 1e-100 used to raise OverflowError, but now gives the requested 120
897 significant digits instead.

904 10.6.
Ronald Oussoren315cd0c2009-11-19 16:25:21 +0000905
Georg Brandlba83f822010-03-14 09:50:54 +0000906- Issue #7117: ``repr(x)`` for a float x returns a result based on the shortest
907 decimal string that's guaranteed to round back to x under correct rounding
908 (with round-half-to-even rounding mode). Previously it gave a string based on
909 rounding x to 17 decimal digits. repr(x) for a complex number behaves
910 similarly. On platforms where the correctly-rounded strtod and dtoa code is
911 not supported (see below), repr is unchanged.
Mark Dickinsonb678de82009-11-19 18:41:49 +0000912
Georg Brandlba83f822010-03-14 09:50:54 +0000913- Issue #7117: On almost all platforms: float-to-string and string-to-float
914 conversions within Python are now correctly rounded. Places these conversions
915 occur include: str for floats and complex numbers; the float and complex
916 constructors; old-style and new-style numeric formatting; serialization and
917 deserialization of floats and complex numbers using marshal, pickle and json;
918 parsing of float and imaginary literals in Python code; Decimal-to-float
919 conversion.
Mark Dickinsonb678de82009-11-19 18:41:49 +0000920
Georg Brandlba83f822010-03-14 09:50:54 +0000921 The conversions use a Python-adapted version of David Gay's well-known dtoa.c,
922 providing correctly-rounded strtod and dtoa C functions. This code is
923 supported on Windows, and on Unix-like platforms using gcc, icc or suncc as
924 the C compiler. There may be a small number of platforms on which correct
925 operation of this code cannot be guaranteed, so the code is not used: notably,
926 this applies to platforms where the C double format is not IEEE 754 binary64,
927 and to platforms on x86 hardware where the x87 FPU is set to 64-bit precision
928 and Python's configure script is unable to determine how to change the FPU
929 precision. On these platforms conversions use the platform strtod and dtoa,
930 as before.
Mark Dickinsonb678de82009-11-19 18:41:49 +0000931
Georg Brandlba83f822010-03-14 09:50:54 +0000932- Issue #7117: Backport round implementation from Python 3.x. ``round()`` now
933 uses the correctly-rounded string <-> float conversions described above (when
934 available), and so produces correctly rounded results that will display nicely
935 under the float repr. There are two related small changes: (1) round now
936 accepts any class with an ``__index__()`` method for its second argument (but
937 no longer accepts floats for the second argument), and (2) an excessively
938 large second integer argument (e.g., ``round(1.234, 10**100)``) no longer
939 raises an exception.

Georg Brandlba83f822010-03-14 09:50:54 +00001033- Issue #6347: Include inttypes.h as well as stdint.h in pyport.h. This fixes a
1034 build failure on HP-UX: int32_t and uint32_t are defined in inttypes.h instead
1035 of stdint.h on that platform.
Mark Dickinson2f865b92009-06-30 15:32:30 +00001036

1071 literals.
Mark Dickinsona4e0efa2009-05-20 18:43:07 +00001072

Mark Dickinsonb1d45852009-05-11 15:33:08 +00001081
Georg Brandlba83f822010-03-14 09:50:54 +00001082 (1) inf and nan strings with trailing whitespace were incorrectly rejected;
1083 (2) parsing of strings representing infinities and nans was locale aware; and
1084 (3) the interpretation of fromhex('-nan') didn't match that of float('-nan').
Eric Smitha985a3a2009-05-05 18:26:08 +00001085
Georg Brandlba83f822010-03-14 09:50:54 +00001086- Issue #5920: For ``float.__format__()``, change the behavior with the empty
1087 presentation type (that is, not one of 'e', 'f', 'g', or 'n') to be like 'g'
1088 but with at least one decimal point and with a default precision
1089 of 12. Previously, the behavior the same but with a default precision of 6.
1090 This more closely matches ``str()``, and reduces surprises when adding
1091 alignment flags to the empty presentation type. This also affects the new
1092 complex.__format__ in the same way.
1093
1094- Issue #5890: In subclasses of 'property' the __doc__ attribute was shadowed by
1095 classtype's, even if it was None. property now inserts the __doc__ into the
1096 subclass instance __dict__.

Antoine Pitrouf8387af2009-03-23 18:41:45 +00001156- Issue #4688: Add a heuristic so that tuples and dicts containing only
Georg Brandlba83f822010-03-14 09:50:54 +00001157 untrackable objects are not tracked by the garbage collector. This can reduce
1158 the size of collections and therefore the garbage collection overhead on
1159 long-running programs, depending on their particular use of datatypes.

1166 internal representation of integers, for performance reasons. Base 2**30 is
1167 enabled by default on 64-bit machines. Add --enable-big-digits option to
1168 configure, which overrides the default. Add sys.long_info structseq to
1169 provide information about the internal format.

Georg Brandlba83f822010-03-14 09:50:54 +00001275- Issue #4445: Replace ``sizeof(PyStringObject)`` with
1276 ``offsetof(PyStringObject, ob_sval) + 1`` when allocating memory for str
1277 instances. On a typical machine this saves 3 bytes of memory (on average) per

Amaury Forgeot d'Arcdc619012008-11-22 20:01:18 +00001280- Issue #3996: On Windows, the PyOS_CheckStack function would cause the

1283
Georg Brandlba83f822010-03-14 09:50:54 +00001284- Issue #3689: The list reversed iterator now supports __length_hint__ instead

1289
Georg Brandlba83f822010-03-14 09:50:54 +00001290- Issue #4233: Changed semantic of ``_fileio.FileIO``'s ``close()`` method on
1291 file objects with closefd=False. The file descriptor is still kept open but
1292 the file object behaves like a closed file. The ``FileIO`` object also got a
1293 new readonly attribute ``closefd``.

Benjamin Peterson399b1fe2008-10-25 02:53:28 +00001313- Using ``nonlocal`` as a variable name will now raise a Py3k SyntaxWarning

Georg Brandlba83f822010-03-14 09:50:54 +00001316- On windows, ``os.chdir()`` given unicode was not working if
1317 GetCurrentDirectoryW returned a path longer than MAX_PATH. (But It's doubtful
1318 this code path is really executed because I cannot move to such directory on
1319 win2k)

Georg Brandlba83f822010-03-14 09:50:54 +00001321- Issue #4069: When ``set.remove(element)`` is used with a set element, the
1322 element is temporarily replaced with an equivalent frozenset. But the
1323 eventual KeyError would always report the empty ``frozenset()`` as the missing
1324 key. Now it correctly refers to the initial element.

1343
Walter Dörwalded960ac2009-05-03 22:36:33 +00001344- Issue #5108: Handle %s like %S and %R in PyUnicode_FromFormatV(): Call
1345 PyUnicode_DecodeUTF8() once, remember the result and output it in a second
1346 step. This avoids problems with counting UTF-8 bytes that ignores the effect
1347 of using the replace error handler in PyUnicode_DecodeUTF8().
1348
Walter Dörwald726ba8e2009-05-06 14:32:35 +00001349- Issue #3739: The unicode-internal encoder now reports the number of characters

1351
Georg Brandlba83f822010-03-14 09:50:54 +00001352- Issue #2422: When compiled with the ``--with-valgrind`` option, the pymalloc
1353 allocator will be automatically disabled when running under Valgrind. This
1354 gives improved memory leak detection when running under Valgrind, while taking
1355 advantage of pymalloc at other times.

2522 __long__ method could be packed by 'q', 'Q', '*q', '*Q'; for x with
2523 neither __int__ nor __long__, TypeError used to be raised (with a

Martin v. Löwis9fa5a282008-09-11 06:53:30 +00002720- Issue #3642: Suppress warning in obmalloc when size_t is larger than uint.
2721
Amaury Forgeot d'Arc05e34492008-09-10 22:04:45 +00002722- Issue #3743: In a few places, PY_FORMAT_SIZE_T was incorrectly used with
2723 PyString_FromFormat or PyErr_Format to display size_t values. The macro
2724 PY_FORMAT_SIZE_T is designed to select the correct format for the OS
2725 ``printf`` function, whereas PyString_FromFormat has an independent
2726 implementation and uses "%zd" on all platforms for size_t values.
2727 This makes a difference on win64, where ``printf`` needs "%Id" to display
2728 64bit values.
2729
Benjamin Peterson97179b02008-09-09 20:55:01 +00002730- Issue #3634: _weakref.ref(Exception).__init__() gave invalid return value on

2734 object; previously an int would be returned for small values. the __long__
2735 method is allowed to return either an int or a long, but the behaviour of
2736 float objects should not change to respect backward compatibility.
2737
Amaury Forgeot d'Arc3571fbf2008-09-01 19:52:00 +00002738- Issue #3751: str.rpartition would perform a left-partition when called with
2739 a unicode argument.

Vinay Sajip35e3b032008-09-01 14:33:59 +00002744 PyArg_ParseTuple and friends, which occurred when the argument for "s*"
Antoine Pitroud4ae97b2008-08-29 18:39:48 +00002745 was correctly parsed but parsing of subsequent arguments failed.
2746
Vinay Sajip35e3b032008-09-01 14:33:59 +00002747- Issue #2534: speed up isinstance() and issubclass() by 50-70%, so as to
Antoine Pitrou0668c622008-08-26 22:42:08 +00002748 match Python 2.5 speed despite the __instancecheck__ / __subclasscheck__
2749 mechanism. In the process, fix a bug where isinstance() and issubclass(),
2750 when given a tuple of classes as second argument, were looking up
2751 __instancecheck__ / __subclasscheck__ on the tuple rather than on each
2752 type object.
2753
Neal Norwitz18aa3882008-08-24 05:04:52 +00002754- Fix crashes on memory allocation failure found with failmalloc.
2755
2756- Fix memory leaks found with valgrind and update suppressions file.

2823 warnings.catch_warnings() along with some API cleanup. Expanding the tests
2824 for catch_warnings() also led to an improvement in the raising of a

2897-----------------
2898
Guido van Rossumf8402962008-08-20 15:01:50 +00002899- Issue #1878: Remove Py_TPFLAGS_HAVE_VERSION_TAG from
2900 Py_TPFLAGS_DEFAULT when not building the core. This means 3rd party
2901 extensions do not automatically benefit from the class attribute
2902 cache; they will have to explicitly add Py_TPFLAGS_HAVE_VERSION_TAG
2903 to their tp_flags field if they care. This is a backwards
2904 compatibility feature; in 3.0, all types will use the cache by
2905 default.
2906
Benjamin Petersonf647dc12008-08-20 01:27:30 +00002907- Keyword arguments can now follow starred arguments. (``f(a, *args,
2908 keyword=23)`` is now valid syntax.)
2909
Thomas Heller0ad5ae02008-08-19 19:25:04 +00002910- ctypes function pointers that are COM methods have a boolean True
2911 value again.
2912
Martin v. Löwisf91d46a2008-08-12 14:49:50 +00002913- Issue #3139: Make buffer-interface thread-safe wrt. PyArg_ParseTuple,
2914 by denying s# to parse objects that have a releasebuffer procedure,
2915 and introducing s*.
2916
Georg Brandl1e13ea92008-08-11 09:07:59 +00002917- Issue #3537: Fix an assertion failure when an empty but presized dict
2918 object was stored in the freelist.

Mark Dickinsonb6467572008-08-04 21:30:09 +00002920- Issue #1481296: Make long(float('nan')) and int(float('nan')) raise
2921 ValueError consistently across platforms.
2922
Amaury Forgeot d'Arc39fd6722008-07-31 21:28:03 +00002923- Issue #3479: On platforms where sizeof(int) is smaller than sizeof(long)
2924 (64bit Unix, for example), unichr() would truncate its argument and return
2925 u'\x00' for unichr(2**32). Now it properly raises an OverflowError.
2926
Neal Norwitze7d8be82008-07-31 17:17:14 +00002927- Apply security patches from Apple.
2928
Amaury Forgeot d'Arc246daed2008-07-31 00:42:16 +00002929- Issue #2542: Now that issubclass() may call arbitrary code, ensure that

Antoine Pitrou92f82162008-07-25 22:22:08 +00002932- Issue #1819: function calls with several named parameters are now on
2933 average 35% faster (as measured by pybench).
2934
Amaury Forgeot d'Arce4921fe2008-07-21 22:00:38 +00002935- Issue #2378: An unexpected UnboundLocalError or NameError could appear when
2936 the python debugger steps into a class statement: the free variables (local
2937 variables defined in an outer scope) would be deleted from the outer scope.
2938
Gregory P. Smith0470bab2008-07-22 04:46:32 +00002939- Issue #2620: Overflow checking when allocating or reallocating memory
2940 was not always being done properly in some python types and extension
2941 modules. PyMem_MALLOC, PyMem_REALLOC, PyMem_NEW and PyMem_RESIZE have
2942 all been updated to perform better checks and places in the code that
2943 would previously leak memory on the error path when such an allocation
2944 failed have been fixed.

2950
Benjamin Petersone977ad42008-08-20 01:42:01 +00002951- The methods ``is_in_tuple()``, ``is_vararg()``, and ``is_keywordarg()`` of
2952 symtable.Symbol have been deprecated for removal in 3.0 and the next release.
2953
Amaury Forgeot d'Arc351ffb82008-08-18 19:23:47 +00002954- Issue #2234: distutils failed for some versions of the cygwin compiler. The
2955 version reported by these tools does not necessarily follow the python
2956 version numbering scheme, so the module is less strict when parsing it.
2957
Nick Coghlanf70385a2008-08-18 12:42:46 +00002958- Issue #2235: Added Py3k warnings for types which will become unhashable
2959 under the stricter __hash__ inheritance rules in 3.0. Several types
2960 which did not meet the rules for hash invariants and were already
2961 unhashable in 3.0 have now been explicitly flagged as unhashable in
2962 2.6 as well (collections.Mapping, collections.Set, unittest.TestSuite,
2963 xml.dom.minidom.NamedNodeMap, numbers.Number, UserList.UserList)
2964
Brett Cannon88f801d2008-08-18 00:46:22 +00002965- Update __all__ for cookielib, csv, os, urllib2, and weakref to include things
2966 imported into the module but exposed as part of the module's API.
2967

2975 by using 's*' instead of 't#'.
2976
Mark Dickinson3e4caeb2009-02-21 20:27:01 +00002977- Issue #2222: Fixed reference leak when occurred os.rename()
Hirokazu Yamamoto7f30a682008-08-17 09:46:56 +00002978 fails unicode conversion on 2nd parameter. (windows only)

2987 after a 302 response in the case of not going through a proxy.
2988
Antoine Pitroub90a8be2008-08-15 21:03:21 +00002989- Issue #2676: in the email package, content-type parsing was hanging on
2990 pathological input because of quadratic or exponential behaviour of a
2991 regular expression.
2992
Antoine Pitrou11ec65d2008-08-14 21:04:30 +00002993- Issue #3476: binary buffered reading through the new "io" library is now
2994 thread-safe.
2995
Brett Cannonbf3157b2008-08-14 05:00:03 +00002996- Silence the DeprecationWarning of rfc822 when it is imported by mimetools
2997 since mimetools itself is deprecated. Because modules are cached, all
2998 subsequent imports of rfc822 will not raise a visible DeprecationWarning.
2999
Antoine Pitrou9fcd4b32008-08-11 17:21:36 +00003000- Issue #3134: shutil referenced undefined WindowsError symbol.

Robert Schuppenies14646332008-08-10 11:01:53 +00003002- Issue #1342811: Fix leak in Tkinter.Menu.delete. Commands associated to
3003 menu entries were not deleted.
3004
Brett Cannon83e81842008-08-09 23:30:55 +00003005- Copied the implementation of reduce() to _functools.reduce() to have a
3006 version that did not raise a DeprecationWarning under -3.
3007
Antoine Pitrou76b8bee2008-08-09 17:27:23 +00003008- Issue #3205: When iterating over a BZ2File fails allocating memory, raise
3009 a MemoryError rather than silently stop the iteration.
3010
Guido van Rossum59ce9012008-08-09 14:55:34 +00003011- Issue #3487: sre "bytecode" validator. Passing invalid "re-bytecode"
3012 to _sre.compile() will now be rejected. This should not affect anybody
3013 since the re.compile() function never generates invalid re-bytecode.
3014
Skip Montanaroa032bf42008-08-08 22:52:51 +00003015- Issue #3436: Make csv.DictReader's fieldnames attribute a property so that
3016 upon first access it can be automatically initialized from the csv file if
3017 it wasn't initialized during instantiation.
3018
Brett Cannon3aa2a492008-08-06 22:28:09 +00003019- Issue #2338: Create imp.reload() to help with transitioning to Python 3.0 as
3020 the reload() built-in has been removed.
3021
Brett Cannon7e30b672008-08-04 21:52:25 +00003022- Changed code in the following modules/packages to remove warnings raised
Brett Cannonc1b76e42008-08-09 23:06:16 +00003023 while running under the ``-3`` flag: aifc, asynchat, asyncore, bdb, bsddb,

3031 raised an AttributeError.
3032
Benjamin Peterson01a24322008-07-28 23:35:27 +00003033- Issue #2523: Fix quadratic behaviour when read()ing a binary file without
Antoine Pitroude781a42008-08-09 12:43:23 +00003034 asking for a specific length. This problem only affected files opened
3035 using the new "io" module, not the built-in open() function.
Benjamin Peterson01a24322008-07-28 23:35:27 +00003036

3059
Antoine Pitrou5fdfa3e2008-07-25 19:42:26 +00003060- Issue #3394: zipfile.writestr sets external attributes when passed a
3061 file name rather than a ZipInfo instance, so files are extracted with
3062 mode 0600 rather than 000 under Unix.
3063
Gregory P. Smitha36f8fe2008-08-04 00:13:29 +00003064- Issue #1857: subprocess.Popen.poll gained an additional _deadstate keyword
3065 argument in python 2.5, this broke code that subclassed Popen to include its
3066 own poll method. Fixed my moving _deadstate to an _internal_poll method.

3075
Nick Coghlan6e8fef02008-08-18 13:14:22 +00003076- Issue #2235: the C API function PyObject_HashNotImplemented and its
3077 interaction with the tp_hash slot (added in 2.6b2) are now documented
3078
Nick Coghlan2a0c2b12008-08-04 12:47:17 +00003079- Issue #643841: The language reference now provides more detailed
3080 coverage of the lookup process for special methods. The disclaimers
3081 regarding lack of coverage of new-style classes have also been
3082 removed, since the coverage is now fairly reasonable.

3086================================
3087
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00003088*Release date: 17-Jul-2008*
3089
Raymond Hettingere3ae6552008-06-20 04:18:15 +00003090Core and Builtins
3091-----------------
3092
Georg Brandl3e483f62008-07-16 22:57:41 +00003093- Issue #3156: Fix inconsistent behavior of the bytearray type: all
3094 its methods now allow for items objects that can be converted to
3095 an integer using operator.index().
3096
Mark Dickinson64b7e502008-07-16 09:40:03 +00003097- Issue #3360: Fix incorrect parsing of '020000000000.0', which
3098 produced a ValueError instead of giving the correct float.
3099
Eric Smitha5fa5a22008-07-16 00:11:49 +00003100- Issue #3083: Add alternate (#) formatting for bin, oct, hex output
3101 for str.format(). This adds the prefix 0b, 0o, or 0x, respectively.
3102
Mark Dickinson7103aa42008-07-15 19:08:33 +00003103- Issue #3008: the float type has a new instance method 'float.hex'
3104 and a new class method 'float.fromhex' to convert floating-point
3105 numbers to and from hexadecimal strings, respectively.
3106
Nick Coghlan6d6bd442008-07-15 15:40:22 +00003107- Issue #2235: __hash__ is once again inherited by default. To allow
3108 collections.Hashable to remain meaningful in the presence of the
3109 default hash implementation (object.__hash__), it is now possible
3110 to explicit block inheritance of hash by setting __hash__=None at
3111 the Python level, or tp_hash=PyObject_HashNotImplemented at the C
3112 level.
3113
Nick Coghlanb028f502008-07-13 14:52:36 +00003114- Issue #3221: Issue a RuntimeWarning instead of raising SystemError if
3115 the parent module cannot be found while performing an absolute import.
3116 This means that an incorrectly defined __package__ attribute will
3117 now only prevent relative imports in that module rather than causing
3118 all imports from that module to fail.
3119
Nick Coghlan14ff9942008-07-08 14:21:42 +00003120- Issue #2517: Allow unicode messages in Exceptions again by correctly
3121 bypassing the instance dictionary when looking up __unicode__ on
3122 new-style classes.
3123
Amaury Forgeot d'Arcbdd941f2008-07-01 20:38:04 +00003124- Issue #3242: Fix a crash inside the print statement, if sys.stdout is
3125 set to a custom object whose write() method happens to install
3126 another file in sys.stdout.
3127
Amaury Forgeot d'Arc1f40c8a2008-06-30 22:42:40 +00003128- Issue #3088: Corrected a race condition in classes derived from
3129 threading.local: the first member set by a thread could be saved in
3130 another thread's dictionary.
3131
Mark Dickinson1ec2fcd2008-06-20 14:53:43 +00003132- Issue #3004: Minor change to slice.indices(): the start and stop
3133 arguments are now treated identically, making the behaviour easier
3134 to describe and understand. For example, slice(None, -10,
3135 1).indices(9) now returns (0, 0, 1) instead of (0, -1, 1), and
3136 slice(None, 10, -1).indices(10) returns (9, 9, -1) instead of (9,
3137 10, -1).
3138
Georg Brandl278fc502008-07-19 12:46:12 +00003139- Issue #3219: Calling a function with repeated keyword arguments,
3140 f(a=2, a=23), would not cause a syntax error. This was a regression
3141 from 2.4 caused by the switch to the new compiler.
Benjamin Peterson175e4d92008-07-01 19:34:52 +00003142
Georg Brandl278fc502008-07-19 12:46:12 +00003143- Issue #2862: Make int and float freelist management consistent with
3144 other freelists. Changes their CompactFreeList apis into
3145 ClearFreeList apis and calls them via gc.collect().
Gregory P. Smith2fe77062008-07-06 03:35:58 +00003146

3148-------
3149
Thomas Heller57adf222008-08-14 19:10:48 +00003150- Issue #3554: ctypes.string_at and ctypes.wstring_at did call Python
3151 api functions without holding the GIL, which could lead to a fatal
3152 error when they failed.
3153
Martin v. Löwisaabf4042008-08-02 07:20:25 +00003154- Issue #799428: Fix Tkinter.Misc._nametowidget to unwrap Tcl command objects.

Jesse Noller13e9d582008-07-16 14:32:36 +00003162- Issue #3125: Remove copy_reg in multiprocessing and replace it with
3163 ForkingPickler.register() to resolve conflict with ctypes.
3164
Vinay Sajip51e65192008-07-18 09:01:10 +00003165- Issue #3090: Fixed ARCHFLAGS parsing on OS/X
Jesse Noller13e9d582008-07-16 14:32:36 +00003166
Thomas Heller880f5292008-07-15 19:39:38 +00003167- Issue #3313: Fixed a crash when a failed dlopen() call does not set
3168 a valid dlerror() message.
3169
Thomas Heller2bad6572008-07-15 17:19:50 +00003170- Issue #3258: Fixed a crash when a ctypes POINTER type to an
3171 incomplete structure was created.
3172
Brett Cannon3d0b9f02008-07-13 01:15:07 +00003173- Issue #3339: dummy_thread.acquire() should not return None.

3176
Andrew M. Kuchlingcc3f2b12008-07-10 14:43:31 +00003177- Issue #3301: Bisect module behaved badly when lo was negative.
Raymond Hettinger3cd1e422008-07-10 14:03:19 +00003178
Amaury Forgeot d'Arc0f7cddc2008-07-06 21:34:39 +00003179- Issue #839496: SimpleHTTPServer used to open text files in text mode. This is
3180 both unnecessary (HTTP allows text content to be sent in several forms) and
Andrew M. Kuchlingcc3f2b12008-07-10 14:43:31 +00003181 wrong because the actual transmitted size could differ from the
Amaury Forgeot d'Arc0f7cddc2008-07-06 21:34:39 +00003182 content-length. The problem had been corrected in the 2.4 branch, but never
3183 merged into trunk.
3184
Georg Brandle78fbcc2008-07-05 10:13:36 +00003185- Issue #2663: add filtering capability to shutil.copytree().

Vinay Sajip51e65192008-07-18 09:01:10 +00003193 Zip files with archives by setting the 'comment' attribute of a ZipFile.
Martin v. Löwis8c436412008-07-03 12:51:14 +00003194
Vinay Sajip51e65192008-07-18 09:01:10 +00003195- Issue #449227: The rlcompleter module now adds "(" to callable objects
Andrew M. Kuchlingcc3f2b12008-07-10 14:43:31 +00003196 when completed.
Facundo Batista66c52772008-07-02 16:52:55 +00003197
Nick Coghlanc060b0e2008-07-02 13:09:19 +00003198- Issue #3190: Pydoc now hides the automatic module attribute __package__ (the
3199 handling is now the same as that of other special attributes like __name__).
3200
Brett Cannon8bb8fa52008-07-02 01:57:08 +00003201- Issue #2885 (partial): The urllib.urlopen() function has been deprecated for
3202 removal in Python 3.0 in favor of urllib2.urlopen().

Georg Brandl5cc774e2008-06-11 20:28:06 +00003591 PPC64 and x86_64 support in one binary).
Ronald Oussoren5640ce22008-06-05 12:58:24 +00003592
3593 This is controlled by the configure argument ``--with-universal-archs``:
3594
3595 - ``--with-universal-archs=all``: install 4-way universal
3596
3597 - ``--with-universal-archs=32-bit``: install 2-way universal, 32-bit (the default)
3598
3599 - ``--with-universal-archs=64-bit``: install 2-way universal, 64-bit
3600
3601 This option should be used in combination with ``--enable-universalsdk=``.
3602
3603 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 +00003653- Issue #1631171: Re-implement the 'warnings' module in C (the
3654 original Python code has been kept as backup). This will allow for
3655 using the 'warning's machinery in such places as the parser where
3656 use of pure Python code is not possible. Both the ``showarning()``
3657 and ``formatwarning()`` gain an optional 'line' argument which is
3658 not called by default for backwards-compatibility reasons. Setting
3659 ``warnings.showwarning()`` to an implementation that lacks support
3660 for the ``line`` argument will raise a DeprecationWarning.

Georg Brandl3ee81df2008-05-17 18:14:43 +00003723- Issue #2550: The approach used by client/server code for obtaining
3724 ports to listen on in network-oriented tests has been refined in an
3725 effort to facilitate running multiple instances of the entire
3726 regression test suite in parallel without issue.
3727 test_support.bind_port() has been fixed such that it will always
3728 return a unique port -- which wasn't always the case with the
3729 previous implementation, especially if socket options had been set
3730 that affected address reuse (i.e. SO_REUSEADDR, SO_REUSEPORT). The
3731 new implementation of bind_port() will actually raise an exception
3732 if it is passed an AF_INET/SOCK_STREAM socket with either the
3733 SO_REUSEADDR or SO_REUSEPORT socket option set. Furthermore, if
3734 available, bind_port() will set the SO_EXCLUSIVEADDRUSE option on
3735 the socket it's been passed. This currently only applies to
3736 Windows. This option prevents any other sockets from binding to the
3737 host/port we've bound to, thus removing the possibility of the
3738 'non-deterministic' behaviour, as Microsoft puts it, that occurs
3739 when a second SOCK_STREAM socket binds and accepts to a host/port
3740 that's already been bound by another socket. The optional preferred
3741 port parameter to bind_port() has been removed. Under no
3742 circumstances should tests be hard coding ports!
3743
3744 test_support.find_unused_port() has also been introduced, which will
3745 pass a temporary socket object to bind_port() in order to obtain an
3746 unused port. The temporary socket object is then closed and
3747 deleted, and the port is returned. This method should only be used
3748 for obtaining an unused port in order to pass to an external program
3749 (i.e. the -accept [port] argument to openssl's s_server mode) or as
3750 a parameter to a server-oriented class that doesn't give you direct
3751 access to the underlying socket used.
3752
3753 Finally, test_support.HOST has been introduced, which should be used
3754 for the host argument of any relevant socket calls (i.e. bind and
3755 connect).
Trent Nelsone41b0062008-04-08 23:47:30 +00003756
3757 The following tests were updated to following the new conventions:
Georg Brandl3ee81df2008-05-17 18:14:43 +00003758 test_socket, test_smtplib, test_asyncore, test_ssl, test_httplib,

3760 test_asynchat and test_socket_ssl.
3761
Georg Brandl3ee81df2008-05-17 18:14:43 +00003762 It is now possible for multiple instances of the regression test

4031
Fred Drakea8ee94b2008-03-01 02:45:07 +00004032- Issue #2051: pyc and pyo files are no longer created with permission
Barry Warsaw52973612008-03-01 02:23:38 +00004033 644. The mode is now inherited from the py file.
Christian Heimes40346852008-02-23 17:52:07 +00004034
Georg Brandlad61bc82008-02-23 15:11:18 +00004035- Issue #2067: file.__exit__() now calls subclasses' close() method.
4036
4037- Patch #1759: Backport of PEP 3129 class decorators.
Christian Heimes5224d282008-02-23 15:01:05 +00004038
Vinay Sajipb7edfc42008-04-02 21:10:23 +00004039- Issue #1881: An internal parser limit has been increased. Also see
Facundo Batistafc2d0102008-02-23 12:01:13 +00004040 issue 215555 for a discussion.
4041
Eric Smitha73fbe72008-02-23 03:09:44 +00004042- Added the future_builtins module, which contains hex() and oct().
4043 These are the PEP 3127 version of these functions, designed to be
4044 compatible with the hex() and oct() builtins from Python 3.0. They
4045 differ slightly in their output formats from the existing, unchanged
4046 Python 2.6 builtins. The expected usage of the future_builtins
4047 module is:
4048 from future_builtins import hex, oct
4049
Eric Smith7ef40bf2008-02-20 23:34:22 +00004050- Issue #1600: Modifed PyOS_ascii_formatd to use at most 2 digit
4051 exponents for exponents with absolute value < 100. Follows C99
4052 standard. This is a change on Windows, which would use 3 digits.
4053 Also, added 'n' to the formats that PyOS_ascii_formatd understands,
4054 so that any alterations it does to the resulting string will be
4055 available in stringlib/formatter.h (for float.__format__).
4056
Eric Smith5a3c1352008-02-19 13:21:56 +00004057- Implemented PEP 3101, Advanced String Formatting. This adds a new
4058 builtin format(); a format() method for str and unicode; a
4059 __format__() method to object, str, unicode, int, long, float, and
4060 datetime; the class string.Formatter; and the C API
4061 PyObject_Format().
4062
Georg Brandl3ee81df2008-05-17 18:14:43 +00004063- Fixed several potential crashes, all caused by specially crafted
4064 __del__ methods exploiting objects in temporarily inconsistent
4065 state.
Amaury Forgeot d'Arc632fad32008-02-16 20:55:24 +00004066
Vinay Sajipb7edfc42008-04-02 21:10:23 +00004067- Issue #2115: Important speedup in setting __slot__ attributes. Also
Georg Brandl3ee81df2008-05-17 18:14:43 +00004068 prevent a possible crash: an Abstract Base Class would try to access
4069 a slot on a registered virtual subclass.
Amaury Forgeot d'Arc60d6c7f2008-02-15 21:22:45 +00004070
Georg Brandl3ee81df2008-05-17 18:14:43 +00004071- Fixed repr() and str() of complex numbers with infinity or nan as
4072 real or imaginary part.
Christian Heimes2f0da532008-02-15 06:57:08 +00004073
Georg Brandl3ee81df2008-05-17 18:14:43 +00004074- Clear all free lists during a gc.collect() of the highest generation
4075 in order to allow pymalloc to free more arenas. Python may give back
4076 memory to the OS earlier.
Christian Heimes3b718a72008-02-14 12:47:33 +00004077
Georg Brandl3ee81df2008-05-17 18:14:43 +00004078- Issue #2045: Fix an infinite recursion triggered when printing a
4079 subclass of collections.defaultdict, if its default_factory is set
4080 to a bound method.
Amaury Forgeot d'Arcb01aa432008-02-08 00:56:02 +00004081
Christian Heimesf75dbef2008-02-08 00:11:31 +00004082- Fixed a minor memory leak in dictobject.c. The content of the free
4083 list was not freed on interpreter shutdown.
4084
Georg Brandl21e99f42010-03-07 15:23:59 +00004085- Limit free list of method and built-in function objects to 256
Georg Brandl3ee81df2008-05-17 18:14:43 +00004086 entries each.
Christian Heimes6075a822008-02-06 12:44:34 +00004087
Georg Brandl3ee81df2008-05-17 18:14:43 +00004088- Patch #1953: Added ``sys._compact_freelists()`` and the C API
4089 functions ``PyInt_CompactFreeList`` and ``PyFloat_CompactFreeList``
Christian Heimes422051a2008-02-04 18:00:12 +00004090 to compact the internal free lists of pre-allocted ints and floats.
4091
Georg Brandl3ee81df2008-05-17 18:14:43 +00004092- Issue #1983: Fixed return type of fork(), fork1() and forkpty()
4093 calls. Python expected the return type int but the fork familie
4094 returns pi_t.
Christian Heimes951cc0f2008-01-31 23:08:23 +00004095
Georg Brandl3ee81df2008-05-17 18:14:43 +00004096- Issue #1678380: Fix a bug that identifies 0j and -0j when they
4097 appear in the same code unit.
Mark Dickinson105be772008-01-31 22:17:37 +00004098
Georg Brandl3ee81df2008-05-17 18:14:43 +00004099- Issue #2025: Add tuple.count() and tuple.index() methods to comply
4100 with the collections.Sequence API.
Raymond Hettinger5b07ebc2008-02-07 00:54:20 +00004101
Georg Brandl3ee81df2008-05-17 18:14:43 +00004102- Patch #1970 by Antoine Pitrou: Speedup unicode whitespace and
4103 linebreak detection
Christian Heimes4d4f2702008-01-30 11:32:37 +00004104
Georg Brandl3ee81df2008-05-17 18:14:43 +00004105- Added ``PyType_ClearCache()`` and ``sys._clear_type_cache`` to clear
4106 the internal lookup cache for ref leak tests.
Christian Heimes908caac2008-01-27 23:34:59 +00004107
Georg Brandl3ee81df2008-05-17 18:14:43 +00004108- Patch #1473257: generator objects gain a gi_code attribute. This is
4109 the same object as the func_code attribute of the function that
4110 produced the generator.
Georg Brandl0cdf9a32008-01-26 14:14:20 +00004111
Georg Brandl3ee81df2008-05-17 18:14:43 +00004112- Issue #1920: "while 0" statements were completely removed by the
4113 compiler, even in the presence of an "else" clause, which is
4114 supposed to be run when the condition is false. Now the compiler
4115 correctly emits bytecode for the "else" suite.
Amaury Forgeot d'Arc31eaafe2008-01-24 22:59:25 +00004116
Guido van Rossumeead05f2008-01-24 18:21:02 +00004117- A few crashers fixed: weakref_in_del.py (issue #1377858);
4118 loosing_dict_ref.py (issue #1303614, test67.py);
4119 borrowed_ref_[34].py (not in tracker).
4120
Vinay Sajipd7cf32e2008-01-24 12:43:33 +00004121- Issue #1069410: The "can't load dll" message box on Windows is
Christian Heimesb2302ba2008-01-23 17:15:06 +00004122 suppressed while an extension is loaded by calling SetErrorMode in
4123 dynload_win.c. The error is still reported properly.
4124
Georg Brandl3ee81df2008-05-17 18:14:43 +00004125- Issue #1915: Python compiles with --enable-unicode=no again. However
Christian Heimes082c9b02008-01-23 14:20:50 +00004126 several extension methods and modules do not work without unicode
4127 support.
4128
Georg Brandl26543b12008-01-21 18:36:51 +00004129- Issue #1882: when compiling code from a string, encoding cookies in the
4130 second line of code were not always recognized correctly.
4131
Georg Brandl14404b62008-01-19 19:27:05 +00004132- Issue #1679: "0x" was taken as a valid integer literal.
4133
Georg Brandl6caad7d2008-01-26 14:19:22 +00004134- Issue #1865: ``bytes`` as an alias for ``str`` and b"" as an alias "" were
Christian Heimes288e89a2008-01-18 18:24:07 +00004135 added.
4136
Christian Heimesc94e2b52008-01-14 04:13:37 +00004137- sys.float_info / PyFloat_GetInfo: The floating point information
4138 object was converted from a dict to a specialized structseq object.
4139
Georg Brandl3ee81df2008-05-17 18:14:43 +00004140- Patch #1816: Added sys.flags structseq. It exposes the status of
4141 most command line arguments and PYTHON* environment variables.
Christian Heimesf31b69f2008-01-14 03:42:48 +00004142
Georg Brandl3ee81df2008-05-17 18:14:43 +00004143- Objects/structseq.c: Implemented new structseq representation. The
4144 patch makes structseqs (e.g. the return value of os.stat) more
4145 readable.
Christian Heimes9c201962008-01-14 03:33:52 +00004146
Georg Brandl3ee81df2008-05-17 18:14:43 +00004147- Patch #1700288: added a type attribute cache that caches method
4148 accesses, resulting in speedups in heavily object-oriented code.
Amaury Forgeot d'Arce4c270c2008-01-14 00:29:41 +00004149
Neal Norwitz3fc15b82008-01-10 05:42:58 +00004150- Bug #1776: __import__() no longer accepts filenames on any platform.
4151 The first parameter to __import__() must be a valid module name.
Christian Heimes3403f152008-01-09 19:56:33 +00004152
Georg Brandlaed6c662008-01-07 17:25:53 +00004153- Patch #1668: renamed THREADDEBUG envvar to PYTHONTHREADDEBUG.
4154
Georg Brandl3ee81df2008-05-17 18:14:43 +00004155- Patch #602345: Add -B command line option, PYTHONDONTWRITEBYTECODE
4156 envvar and sys.dont_write_bytecode attribute. All these can be set
4157 to forbid Python to attempt to write compiled bytecode files.
Georg Brandl2da0fce2008-01-07 17:09:35 +00004158
Georg Brandl3ee81df2008-05-17 18:14:43 +00004159- Improve some exception messages when Windows fails to load an
4160 extension module. Now we get for example '%1 is not a valid Win32
4161 application' instead of 'error code 193'.
Amaury Forgeot d'Arce0b76952008-01-04 02:04:15 +00004162
Georg Brandl3ee81df2008-05-17 18:14:43 +00004163- Bug #1481296: Fixed long(float('nan')) != 0L.

Georg Brandl3ee81df2008-05-17 18:14:43 +00004165- Issue #1640: Added math.isinf(x), math.isnan(x) and math.copysign(x,
4166 y) functions.
Christian Heimese2ca4242008-01-03 20:23:15 +00004167
Christian Heimes0a8143f2007-12-18 23:22:54 +00004168- Issue #1635: Platform independent creation and representation of NaN
Georg Brandl3ee81df2008-05-17 18:14:43 +00004169 and INF. float("nan"), float("inf") and float("-inf") now work on
4170 every platform with IEEE 754 semantics.
Christian Heimes0a8143f2007-12-18 23:22:54 +00004171
Georg Brandl3ee81df2008-05-17 18:14:43 +00004172- Compiler now generates simpler and faster code for dictionary
4173 literals. The oparg for BUILD_MAP now indicates an estimated
4174 dictionary size. There is a new opcode, STORE_MAP, for adding
4175 entries to the dictionary.
Raymond Hettingerfd7ed402007-12-18 21:24:09 +00004176
Georg Brandl3ee81df2008-05-17 18:14:43 +00004177- Issue #1638: %zd configure test fails on Linux.

Georg Brandl3ee81df2008-05-17 18:14:43 +00004182- Issue #1538: Avoid copying string in split/rsplit if the split char
4183 is not found.
Skip Montanaro26015492007-12-08 15:33:24 +00004184
Andrew M. Kuchling395fe442007-12-05 13:27:20 +00004185- Issue #1553: An erroneous __length_hint__ can make list() raise a
Christian Heimes7cc1c6f2007-12-05 12:52:34 +00004186 SystemError.
4187
Nick Coghlanef01d822007-12-03 12:55:17 +00004188- PEP 366: Allow explicit relative imports when executing modules
4189 inside packages with the -m switch via a new module level
4190 __package__ attribute.
4191
Georg Brandl3ee81df2008-05-17 18:14:43 +00004192- Issue #1402: Fix a crash on exit, when another thread is still
4193 running, and if the deallocation of its frames somehow calls the
4194 PyGILState_Ensure() / PyGILState_Release() functions.
Amaury Forgeot d'Arcbe49a902007-11-30 20:37:22 +00004195

Amaury Forgeot d'Arcce7d10c2007-11-24 13:44:17 +00004199 attribute of an empty cell object.
4200
Georg Brandl3ee81df2008-05-17 18:14:43 +00004201- Issue #1460: The utf-7 incremental decoder did not accept truncated
4202 input. It now correctly saves its state between chunks of data.
Amaury Forgeot d'Arcf57375a2007-11-21 01:38:26 +00004203
Georg Brandl3ee81df2008-05-17 18:14:43 +00004204- Patch #1739468: Directories and zipfiles containing a __main__.py
4205 file can now be directly executed by passing their name to the
4206 interpreter. The directory/zipfile is automatically inserted as the
4207 first entry in sys.path.
Nick Coghlan327a39b2007-11-18 11:56:28 +00004208
Georg Brandl3ee81df2008-05-17 18:14:43 +00004209- Issue #1265: Fix a problem with sys.settrace, if the tracing
4210 function uses a generator expression when at the same time the
4211 executed code is closing a paused generator.
Amaury Forgeot d'Arc0d75f092007-11-13 21:54:28 +00004212
Raymond Hettinger1760c8a2007-11-08 02:52:43 +00004213- sets and frozensets now have an isdisjoint() method.
4214
Raymond Hettinger3f8caa32007-10-24 01:28:33 +00004215- optimize the performance of builtin.sum().
4216
Neal Norwitz44f326e2007-10-05 05:29:17 +00004217- Fix warnings found by the new version of the Coverity checker.
4218
Georg Brandl21e99f42010-03-07 15:23:59 +00004219- The enumerate() built-in function is no longer bounded to sequences
Georg Brandl3ee81df2008-05-17 18:14:43 +00004220 smaller than LONG_MAX. Formerly, it raised an OverflowError. Now,
4221 automatically shifts from ints to longs.
Raymond Hettinger8f669372007-10-03 21:18:11 +00004222
Georg Brandl3ee81df2008-05-17 18:14:43 +00004223- Issue #1686386: Tuple's tp_repr did not take into account the
4224 possibility of having a self-referential tuple, which is possible
4225 from C code. Nor did object's tp_str consider that a type's tp_str
4226 could do something that could lead to an inifinite recursion.
4227 Py_ReprEnter() and Py_EnterRecursiveCall(), respectively, fixed the
4228 issues.
Brett Cannon0b14f242007-09-30 19:45:10 +00004229
Georg Brandl3ee81df2008-05-17 18:14:43 +00004230- Issue #1164: It was possible to trigger deadlock when using the
4231 'print' statement to write to a file since the GIL was not released
4232 as needed. Now PyObject_Print() does the right thing along with
4233 various tp_print implementations of the built-in types and those in
4234 the collections module.
Brett Cannon01531592007-09-17 03:28:34 +00004235
Georg Brandl3ee81df2008-05-17 18:14:43 +00004236- Issue #1147: Exceptions were directly allowing string exceptions in
4237 their throw() method even though string exceptions no longer
4238 allowed.
Brett Cannon4c20bc42007-09-11 21:02:28 +00004239
Georg Brandl3ee81df2008-05-17 18:14:43 +00004240- Issue #1096: Prevent a segfault from getting the repr of a very

Brett Cannon1e534b52007-09-07 04:18:30 +00004243- Issue #1202533: Fix infinite recursion calls triggered by calls to
Georg Brandl3ee81df2008-05-17 18:14:43 +00004244 PyObject_Call() never calling back out to Python code to trigger
4245 recursion depth updates/checks. Required the creation of a static
4246 RuntimeError instance in case normalizing an exception put the
4247 recursion check value past its limit. Fixes crashers
4248 infinite_rec_(1|2|4|5).py.
Brett Cannon1e534b52007-09-07 04:18:30 +00004249
Georg Brandl3ee81df2008-05-17 18:14:43 +00004250- Patch #1031213: Decode source line in SyntaxErrors back to its

Neal Norwitz0ac60192007-05-27 04:08:54 +00004263- Add new attribute names for function objects. All the func_* become
Georg Brandl3ee81df2008-05-17 18:14:43 +00004264 __*__ attributes. (Some already existed, e.g., __doc__ and
4265 __name__.)
Neal Norwitz0ac60192007-05-27 04:08:54 +00004266
Neal Norwitz8b2bfbc2007-05-23 06:35:32 +00004267- Add -3 option to the interpreter to warn about features that are
4268 deprecated and will be changed/removed in Python 3.0.
4269

Collin Winter62903052007-05-18 23:11:24 +00004273- except clauses may now be spelled either "except E, target:" or
Georg Brandl3ee81df2008-05-17 18:14:43 +00004274 "except E as target:". This is to provide forwards compatibility
4275 with Python 3.0.
Collin Winter62903052007-05-18 23:11:24 +00004276
Brett Cannon229cee22007-05-05 01:34:02 +00004277- Deprecate BaseException.message as per PEP 352.
4278
Georg Brandl3ee81df2008-05-17 18:14:43 +00004279- Issue #1303614: don't expose object's __dict__ when the dict is
Georg Brandl21e99f42010-03-07 15:23:59 +00004280 inherited from a built-in base.
Armin Rigo9790a272007-05-02 19:23:31 +00004281
Vinay Sajip8549ce32007-05-06 17:53:37 +00004282- When __slots__ are set to a unicode string, make it work the same as
Neal Norwitzcbd9ee62007-04-14 05:25:50 +00004283 setting a plain string, ie don't expand to single letter identifiers.
4284
Raymond Hettinger13936692007-04-11 18:40:58 +00004285- Request #1191699: Slices can now be pickled.

Raymond Hettinger4db5fe92007-04-12 04:10:00 +00004287- Request #1193128: str.translate() now allows a None argument for
4288 translations that only remove characters without re-mapping the
4289 remaining characters.
4290
Georg Brandl5cb76c12007-03-21 09:00:39 +00004291- Patch #1682205: a TypeError while unpacking an iterable is no longer
4292 masked by a generic one with the message "unpack non-sequence".

4295
Guido van Rossum143b5642007-03-23 04:58:42 +00004296- Bug #1683368: The object.__init__() and object.__new__() methods are
4297 now stricter in rejecting excess arguments. The only time when
4298 either allows excess arguments is when it is not overridden and the
4299 other one is. For backwards compatibility, when both are
4300 overridden, it is a deprecation warning (for now; maybe a Py3k
Guido van Rossum234b1ff2007-03-23 19:39:01 +00004301 warning later). Also, type.__init__() insists on the same signature
4302 as supported by type.__new__().
Guido van Rossum143b5642007-03-23 04:58:42 +00004303
Georg Brandl3ee81df2008-05-17 18:14:43 +00004304- Patch #1675423: PyComplex_AsCComplex() now tries to convert an
4305 object to complex using its __complex__() method before falling back
4306 to the __float__() method. Therefore, the functions in the cmath
4307 module now can operate on objects that define a __complex__()
4308 method.

4312 same slot names.

4325
Georg Brandl7b9c5552007-03-12 14:30:05 +00004326- Bug #1678647: write a newline after printing an exception in any
4327 case, even when converting the value to a string failed.
4328
Georg Brandl871f1bc2007-03-12 13:17:36 +00004329- The dir() function has been extended to call the __dir__() method on
Georg Brandl3ee81df2008-05-17 18:14:43 +00004330 its argument, if it exists. If not, it will work like before. This
4331 allows customizing the output of dir() in the presence of a
4332 __getattr__().

Collin Winter276887b2007-03-12 16:11:39 +00004334- Patch #922167: Python no longer segfaults when faced with infinitely
4335 self-recursive reload() calls (as reported by bug #742342).
4336

4341 parthensized forms. This means complex(repr(x)) now works instead of
4342 raising a ValueError.
Collin Wintere38051d2007-03-09 20:33:07 +00004343
Georg Brandlaa2321b2007-03-07 00:40:28 +00004344- Patch #703779: unset __file__ in __main__ after running a file. This
Georg Brandl3ee81df2008-05-17 18:14:43 +00004345 makes the filenames the warning module prints much more sensible
4346 when a PYTHONSTARTUP file is used.
Georg Brandlaa2321b2007-03-07 00:40:28 +00004347

Georg Brandl0fca97a2007-03-05 22:28:08 +00004359- Patch #1674228: when assigning a slice (old-style), check for the
4360 sq_ass_slice instead of the sq_slice slot.
4361
Georg Brandl3ee81df2008-05-17 18:14:43 +00004362- When printing an unraisable error, don't print exceptions. before
4363 the name. This duplicates the behavior whening normally printing
4364 exceptions.

4373 created a weakref on itself during a __del__ call for new-style
4374 classes (classic classes still have the bug).

4415 embedded in the string to convert.
4416
Georg Brandl846f73a2006-10-08 07:11:54 +00004417- Bug #1569998: break inside a try statement (outside a loop) is now

Georg Brandl3ee81df2008-05-17 18:14:43 +00004465 generator expressions (x for x, in ... ) works again. Fixing this
4466 problem required changing the .pyc magic number. This means that
4467 .pyc files generated before 2.5c2 will be regenerated.

Georg Brandl3ee81df2008-05-17 18:14:43 +00005274- Issue #829951: In the smtplib module, SMTP.starttls() now complies
5275 with RFC 3207 and forgets any knowledge obtained from the server not
5276 obtained from the TLS negotiation itself. Patch contributed by Bill
5277 Fenner.
Gregory P. Smith2b3ba582008-01-17 08:03:17 +00005278
Georg Brandl3ee81df2008-05-17 18:14:43 +00005279- Issue #1339: The smtplib.SMTP class has been refactored a bit such
Gregory P. Smithbde4ae42008-01-17 08:35:49 +00005280 that the SMTP.starttls() caller no longer needs to call ehlo()
5281 beforehand. SMTP.starttls() now raises an exception of the server
Georg Brandl3ee81df2008-05-17 18:14:43 +00005282 does not claim to support starttls. Adds the
5283 SMTP.ehlo_or_helo_if_needed() method. Patch contributed by Bill

5364 complex, tuple, list, dict, set, and frozenset. Formerly, it would
5365 silently miscode subclasses of those types. Now, it raises a
5366 ValueError instead.
Raymond Hettinger12e94202007-11-07 01:13:09 +00005367

Georg Brandl3ee81df2008-05-17 18:14:43 +00005382 time so that opening a database previously created with the DB_DUP
5383 or DB_DUPSORT flag set will keep the proper behavior on subsequent
5384 opens. Specifically: dictionary assignment to a DB object will
5385 replace all values for a given key when the database allows
5386 duplicate values. DB users should use DB.put(k, v) when they want
5387 to store duplicates; not DB[k] = v.
Gregory P. Smithec10a4a2007-11-05 02:32:26 +00005388

5394 characters with ASCII value less than 32. Also, it correctly quotes
5395 dots only if they occur on a single line, as opposed to the previous
5396 behavior of quoting dots if they are the second character of any
5397 line.
Georg Brandl4aef7272007-03-13 22:49:43 +00005398

5735 PyLong_FromSsize_t public functions.
Georg Brandl6caad7d2008-01-26 14:19:22 +00005736
5737- Patch #1720595: add T_BOOL to the range of structmember types.
5738
5739- Issue #1534: Added ``PyFloat_GetMax()``, ``PyFloat_GetMin()`` and
5740 ``PyFloat_GetInfo()`` to the float API.
5741
Georg Brandl3ee81df2008-05-17 18:14:43 +00005742- Issue #1521: On 64bit platforms, using PyArgs_ParseTuple with the t#
5743 of w# format code incorrectly truncated the length to an int, even
5744 when PY_SSIZE_T_CLEAN is set. The str.decode method used to return
5745 incorrect results with huge strings.
Georg Brandl6caad7d2008-01-26 14:19:22 +00005746
Georg Brandl3ee81df2008-05-17 18:14:43 +00005747- Issue #1629: Renamed Py_Size, Py_Type and Py_Refcnt to Py_SIZE,
5748 Py_TYPE and Py_REFCNT.

Georg Brandl3ee81df2008-05-17 18:14:43 +00005750- PEP 3123: Provide forward compatibility with Python 3.0, while
5751 keeping backwards compatibility. Add Py_Refcnt, Py_Type, Py_Size,
5752 and PyVarObject_HEAD_INIT.
Georg Brandl6caad7d2008-01-26 14:19:22 +00005753
Georg Brandl3ee81df2008-05-17 18:14:43 +00005754- Py_ssize_t fields work in structmember when HAVE_LONG_LONG is not
5755 defined.
Georg Brandl6caad7d2008-01-26 14:19:22 +00005756
5757- Patch #1733960: Allow T_LONGLONG to accept ints.
5758
5759- T_PYSSIZET can now be used in PyMemberDef lists for Py_ssize_t members.
5760
Christian Heimes000a0742008-01-03 22:16:32 +00005761- Added a new API function ``PyImport_ImportModuleNoBlock``.

Georg Brandl6caad7d2008-01-26 14:19:22 +00005763- Bug #1637022: Prefix AST symbols with _Py_.
5764
5765- Fix some leftovers from the conversion from int to Py_ssize_t
5766 (relevant to strings and sequences of more than 2**31 items).
5767
5768- Make _PyGILState_NoteThreadState() static, it was not used anywhere
5769 outside of pystate.c and should not be necessary.
5770
Georg Brandl3ee81df2008-05-17 18:14:43 +00005771- ``PyImport_Import`` and ``PyImport_ImportModule`` now always do
5772 absolute imports. In earlier versions they might have used relative
5773 imports under some conditions.
Christian Heimes000a0742008-01-03 22:16:32 +00005774
Georg Brandl3ee81df2008-05-17 18:14:43 +00005775- Added case insensitive comparison methods ``PyOS_stricmp(char*,
5776 char*)`` and ``PyOS_strnicmp(char*, char*, Py_ssize_t)``.
Christian Heimes000a0742008-01-03 22:16:32 +00005777
Georg Brandl3ee81df2008-05-17 18:14:43 +00005778- Bug #1542693: remove semi-colon at end of PyImport_ImportModuleEx
5779 macro so it can be used as an expression.

Georg Brandl3ee81df2008-05-17 18:14:43 +00005785- Patch #1706: Drop support for Win9x, WinME and NT4. Python now
5786 requires Windows 2000 or greater. The _WINVER and NTDDI_VERSION
5787 macros are set to Win2k for x86/32bit builds and WinXP for AMD64
5788 builds.

Georg Brandl3ee81df2008-05-17 18:14:43 +00005803- Removed the macfs module. It had been deprecated since Python 2.5.
5804 This lead to the deprecation of macostools.touched() as it relied
5805 solely on macfs and was a no-op under OS X.
