38 and keywords.
39
Antoine Pitroua5c4b552010-04-22 23:33:02 +000040- Issue #8108: Fix the unwrap() method of SSL objects when the socket has

101-----------------
102
Philip Jenveyaebbaeb2010-04-06 23:24:45 +0000103- Issue #7301: Add environment variable $PYTHONWARNINGS.
104
Benjamin Peterson3a1dfa22010-04-06 21:50:00 +0000105- Issue #8329: Don't return the same lists from select.select when no fds are
106 changed.

Mark Dickinson82791672010-04-06 16:47:55 +0000108- Issue #8259: 1L << (2**31) no longer produces an 'outrageous shift error'
109 on 64-bit machines. The shift count for either left or right shift is

117
Eric Smithd44b2fc2010-04-02 12:30:56 +0000118- Issue #7994: Issue a PendingDeprecationWarning if object.__format__
119 is called with a non-empty format string. This is an effort to
120 future-proof user code. If a derived class does not currently
121 implement __format__ but later adds its own __format__, it would
122 most likely break user code that had supplied a format string. This
123 will be changed to a DeprecationWaring in Python 3.3 and it will be
124 an error in Python 3.4.
125
Antoine Pitroua57df2c2010-03-31 21:32:15 +0000126- Issue #8268: Old-style classes (not just instances) now support weak

Georg Brandlba83f822010-03-14 09:50:54 +0000140 (SIGINT). If an error occurs while importing the site module, the error is
141 printed and Python exits. Initialize the GIL before importing the site
Victor Stinner66644262010-03-10 22:30:19 +0000142 module.

152 using the new attributes `ssl.OPENSSL_VERSION`, `ssl.OPENSSL_VERSION_INFO`
153 and `ssl.OPENSSL_VERSION_NUMBER`.
154
Benjamin Peterson76a23c12010-04-04 23:23:22 +0000155- Issue #8310: Allow dis to examine new style classes.

164
Raymond Hettingera551f312010-04-04 18:34:45 +0000165- the functools module now has a total_ordering() class decorator
Georg Brandl4fabac52010-04-14 08:53:38 +0000166 to simplify the specification of rich comparisons.
Raymond Hettingera551f312010-04-04 18:34:45 +0000167

Mark Dickinsone096e822010-04-02 10:17:07 +0000174- Issue #7279: Comparisons involving a Decimal signaling NaN now
175 signal InvalidOperation instead of returning False. (Comparisons
Mark Dickinsonf3eeca12010-04-02 10:35:12 +0000176 involving a quiet NaN are unchanged.) Also, Decimal quiet NaNs
177 are now hashable; Decimal signaling NaNs remain unhashable.

185 argument `-` which tells it to read files to compile from stdin. Each line
186 is read on demand and the named file is compiled immediately. (Original
187 patch by Piotr Ożarowski).
188
189- Issue #3135: Add inspect.getcallargs, which binds arguments to a function
190 like a normal call.
Benjamin Peterson7e213252010-03-30 17:58:13 +0000191
Florent Xicluna58b65662010-03-30 16:29:03 +0000192- Backwards incompatible change: Unicode codepoints line tabulation (0x0B) and
193 form feed (0x0C) are now considered linebreaks, as specified in Unicode
194 Standard Annex #14. See issue #7643.

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

232 Also, enable the SSL_MODE_AUTO_RETRY flag on SSL sockets, so that blocking
233 reads and writes are always retried by OpenSSL itself.

Mark Dickinson4846a8e2010-04-03 14:05:10 +0000297- Issue #8300: When passing a non-integer argument to struct.pack with any
298 integer format code, struct.pack first attempts to convert the non-integer
299 using its __index__ method. If that method is non-existent or raises
300 TypeError it goes on to try the __int__ method, as described below.
301
Georg Brandlba83f822010-03-14 09:50:54 +0000302- Issue #1530559: When passing a non-integer argument to struct.pack with *any*
303 integer format code (one of 'bBhHiIlLqQ'), struct.pack attempts to use the
304 argument's __int__ method to convert to an integer before packing. It also
305 produces a DeprecationWarning in this case. (In Python 2.6, the behaviour
306 was inconsistent: __int__ was used for some integer codes but not for others,
307 and the set of integer codes for which it was used differed between native
308 packing and standard packing.)

704Core and Builtins
705-----------------
706
Georg Brandlba83f822010-03-14 09:50:54 +0000707- The ``__complex__()`` method is now looked up on the class of instances to
708 make it consistent with other special methods.

712
Mark Dickinson1b34d252010-01-01 17:27:30 +0000713- Issue #5080: A number of functions and methods previously produced a
Georg Brandlba83f822010-03-14 09:50:54 +0000714 DeprecationWarning when passed a float argument where an integer was expected.
715 These functions and methods now raise TypeError instead. The majority of the
716 effects of this change are in the extension modules, but some core functions
717 and methods are affected: notably the 'chr', 'range' and 'xrange' builtins,
718 and many unicode/str methods.

730
Georg Brandlba83f822010-03-14 09:50:54 +0000731- Issue #1811: Improve accuracy and cross-platform consistency for true division
732 of integers: the result of a/b is now correctly rounded for ints a and b (at
733 least on IEEE 754 platforms), and in particular does not depend on the
734 internal representation of a long.

742
Georg Brandlba83f822010-03-14 09:50:54 +0000743 These executables now work properly with the arch(1) command: ``arch -ppc
744 python`` will start a universal binary version of python in PPC mode (unlike
745 previous releases).

Georg Brandlba83f822010-03-14 09:50:54 +0000883- Issue #3382: 'F' formatting for float and complex now convert the result to
884 upper case. This only affects 'inf' and 'nan', since 'f' no longer converts
885 to 'g' for large values.
Amaury Forgeot d'Arcd7288712009-12-01 21:51:04 +0000886
Georg Brandlba83f822010-03-14 09:50:54 +0000887- Remove switch from "%f" formatting to "%g" formatting for floats larger than
888 1e50 in absolute value.
Mark Dickinson9dd5e162009-11-23 20:54:09 +0000889
Georg Brandlba83f822010-03-14 09:50:54 +0000890- Remove restrictions on precision when formatting floats. E.g., "%.120g" %

899 10.6.
Ronald Oussoren315cd0c2009-11-19 16:25:21 +0000900
Georg Brandlba83f822010-03-14 09:50:54 +0000901- Issue #7117: ``repr(x)`` for a float x returns a result based on the shortest
902 decimal string that's guaranteed to round back to x under correct rounding
903 (with round-half-to-even rounding mode). Previously it gave a string based on
904 rounding x to 17 decimal digits. repr(x) for a complex number behaves
905 similarly. On platforms where the correctly-rounded strtod and dtoa code is
906 not supported (see below), repr is unchanged.
Mark Dickinsonb678de82009-11-19 18:41:49 +0000907
Georg Brandlba83f822010-03-14 09:50:54 +0000908- Issue #7117: On almost all platforms: float-to-string and string-to-float
909 conversions within Python are now correctly rounded. Places these conversions
910 occur include: str for floats and complex numbers; the float and complex
911 constructors; old-style and new-style numeric formatting; serialization and
912 deserialization of floats and complex numbers using marshal, pickle and json;
913 parsing of float and imaginary literals in Python code; Decimal-to-float
914 conversion.
Mark Dickinsonb678de82009-11-19 18:41:49 +0000915
Georg Brandlba83f822010-03-14 09:50:54 +0000916 The conversions use a Python-adapted version of David Gay's well-known dtoa.c,
917 providing correctly-rounded strtod and dtoa C functions. This code is
918 supported on Windows, and on Unix-like platforms using gcc, icc or suncc as
919 the C compiler. There may be a small number of platforms on which correct
920 operation of this code cannot be guaranteed, so the code is not used: notably,
921 this applies to platforms where the C double format is not IEEE 754 binary64,
922 and to platforms on x86 hardware where the x87 FPU is set to 64-bit precision
923 and Python's configure script is unable to determine how to change the FPU
924 precision. On these platforms conversions use the platform strtod and dtoa,
925 as before.

Georg Brandlba83f822010-03-14 09:50:54 +0000927- Issue #7117: Backport round implementation from Python 3.x. ``round()`` now
928 uses the correctly-rounded string <-> float conversions described above (when
929 available), and so produces correctly rounded results that will display nicely
930 under the float repr. There are two related small changes: (1) round now
931 accepts any class with an ``__index__()`` method for its second argument (but
932 no longer accepts floats for the second argument), and (2) an excessively
933 large second integer argument (e.g., ``round(1.234, 10**100)``) no longer
934 raises an exception.

Georg Brandlba83f822010-03-14 09:50:54 +00001028- Issue #6347: Include inttypes.h as well as stdint.h in pyport.h. This fixes a
1029 build failure on HP-UX: int32_t and uint32_t are defined in inttypes.h instead
1030 of stdint.h on that platform.
Mark Dickinson2f865b92009-06-30 15:32:30 +00001031

Georg Brandlba83f822010-03-14 09:50:54 +00001053 the various profiling modules (profile, cProfile). Patch by Hagen Fürstenau.
Antoine Pitrou46dbe272009-05-30 21:27:00 +00001054
Georg Brandlba83f822010-03-14 09:50:54 +00001055- Issue #5982: staticmethod and classmethod now expose the wrapped function with
1056 ``__func__``.

1062 statement and correctly lookup the __enter__ and __exit__ special methods.
1063
Georg Brandlba83f822010-03-14 09:50:54 +00001064- Issue #5829: complex("1e500") no longer raises OverflowError. This makes it
1065 consistent with float("1e500") and interpretation of real and imaginary
1066 literals.
Mark Dickinsona4e0efa2009-05-20 18:43:07 +00001067
Hirokazu Yamamotoa4f90182009-05-17 02:58:36 +00001068- Issue #3527: Removed Py_WIN_WIDE_FILENAMES which is not used any more.
1069
Georg Brandlba83f822010-03-14 09:50:54 +00001070- ``__instancecheck__()`` and ``__subclasscheck__()`` are now completely ignored
1071 on classic classes and instances.
Benjamin Petersoneb9fb2c2009-05-16 22:46:11 +00001072
Georg Brandlba83f822010-03-14 09:50:54 +00001073- Issue #5994: The marshal module now has docstrings.
R. David Murray525cffc2009-05-13 13:07:14 +00001074
Mark Dickinsonb1d45852009-05-11 15:33:08 +00001075- Issue #5981: Fix three minor inf/nan issues in float.fromhex:
Mark Dickinsonb1d45852009-05-11 15:33:08 +00001076
Georg Brandlba83f822010-03-14 09:50:54 +00001077 (1) inf and nan strings with trailing whitespace were incorrectly rejected;
1078 (2) parsing of strings representing infinities and nans was locale aware; and
1079 (3) the interpretation of fromhex('-nan') didn't match that of float('-nan').
Eric Smitha985a3a2009-05-05 18:26:08 +00001080
Georg Brandlba83f822010-03-14 09:50:54 +00001081- Issue #5920: For ``float.__format__()``, change the behavior with the empty
1082 presentation type (that is, not one of 'e', 'f', 'g', or 'n') to be like 'g'
1083 but with at least one decimal point and with a default precision
1084 of 12. Previously, the behavior the same but with a default precision of 6.
1085 This more closely matches ``str()``, and reduces surprises when adding
1086 alignment flags to the empty presentation type. This also affects the new
1087 complex.__format__ in the same way.
1088
1089- Issue #5890: In subclasses of 'property' the __doc__ attribute was shadowed by
1090 classtype's, even if it was None. property now inserts the __doc__ into the
1091 subclass instance __dict__.
R. David Murray7ba8e1c2009-05-04 22:16:24 +00001092
Antoine Pitrou653dece2009-05-04 18:32:32 +00001093- Issue #4426: The UTF-7 decoder was too strict and didn't accept some legal
Georg Brandlba83f822010-03-14 09:50:54 +00001094 sequences. Patch by Nick Barnes and Victor Stinner.
Antoine Pitrou653dece2009-05-04 18:32:32 +00001095
Georg Brandlba83f822010-03-14 09:50:54 +00001096- Issue #1588: Add complex.__format__. For example, ``format(complex(1, 2./3),
1097 '.5')`` now produces a sensible result.
Eric Smith9139cc62009-04-30 00:58:58 +00001098

1109 _PyOS_double_to_string or PyOS_double_to_string.
1110
Benjamin Peterson5083dc52009-04-25 00:41:22 +00001111- Issue #5283: Setting __class__ in __del__ caused a segfault.
1112
Georg Brandlba83f822010-03-14 09:50:54 +00001113- Issue #5816: ``complex(repr(z))`` now recovers z exactly, even when z involves
1114 nans, infs or negative zeros.

Georg Brandlba83f822010-03-14 09:50:54 +00001122- Issue #5772: For float.__format__, don't add a trailing ".0" if we're using no
1123 type code and we have an exponent.
Eric Smithaca19e62009-04-22 13:29:05 +00001124
Georg Brandlba83f822010-03-14 09:50:54 +00001125- Issue #3166: Make long -> float (and int -> float) conversions correctly

Antoine Pitrouf8387af2009-03-23 18:41:45 +00001151- Issue #4688: Add a heuristic so that tuples and dicts containing only
Georg Brandlba83f822010-03-14 09:50:54 +00001152 untrackable objects are not tracked by the garbage collector. This can reduce
1153 the size of collections and therefore the garbage collection overhead on
1154 long-running programs, depending on their particular use of datatypes.
Antoine Pitrouf8387af2009-03-23 18:41:45 +00001155

1161 internal representation of integers, for performance reasons. Base 2**30 is
1162 enabled by default on 64-bit machines. Add --enable-big-digits option to
1163 configure, which overrides the default. Add sys.long_info structseq to
1164 provide information about the internal format.
Mark Dickinsonefc82f72009-03-20 15:51:55 +00001165
Benjamin Peterson6ffe8522009-03-18 20:52:15 +00001166- Issue #4034: Fix weird attribute error messages of the traceback object. (As a

1178
Georg Brandlba83f822010-03-14 09:50:54 +00001179- Issue #5247: Improve error message when unknown format codes are used when
1180 using ``str.format()`` with str, unicode, long, int, and float arguments.
Eric Smithe9fb6862009-02-20 14:02:36 +00001181

1284
Georg Brandlba83f822010-03-14 09:50:54 +00001285- Issue #4233: Changed semantic of ``_fileio.FileIO``'s ``close()`` method on
1286 file objects with closefd=False. The file descriptor is still kept open but
1287 the file object behaves like a closed file. The ``FileIO`` object also got a
1288 new readonly attribute ``closefd``.

Benjamin Peterson399b1fe2008-10-25 02:53:28 +00001308- Using ``nonlocal`` as a variable name will now raise a Py3k SyntaxWarning

Georg Brandlba83f822010-03-14 09:50:54 +00001311- On windows, ``os.chdir()`` given unicode was not working if
1312 GetCurrentDirectoryW returned a path longer than MAX_PATH. (But It's doubtful
1313 this code path is really executed because I cannot move to such directory on
1314 win2k)

Georg Brandlba83f822010-03-14 09:50:54 +00001316- Issue #4069: When ``set.remove(element)`` is used with a set element, the
1317 element is temporarily replaced with an equivalent frozenset. But the
1318 eventual KeyError would always report the empty ``frozenset()`` as the missing
1319 key. Now it correctly refers to the initial element.

Walter Dörwalded960ac2009-05-03 22:36:33 +00001339- Issue #5108: Handle %s like %S and %R in PyUnicode_FromFormatV(): Call
1340 PyUnicode_DecodeUTF8() once, remember the result and output it in a second
1341 step. This avoids problems with counting UTF-8 bytes that ignores the effect
1342 of using the replace error handler in PyUnicode_DecodeUTF8().
1343
Walter Dörwald726ba8e2009-05-06 14:32:35 +00001344- Issue #3739: The unicode-internal encoder now reports the number of characters

1346
Georg Brandlba83f822010-03-14 09:50:54 +00001347- Issue #2422: When compiled with the ``--with-valgrind`` option, the pymalloc
1348 allocator will be automatically disabled when running under Valgrind. This
1349 gives improved memory leak detection when running under Valgrind, while taking
1350 advantage of pymalloc at other times.

2517 __long__ method could be packed by 'q', 'Q', '*q', '*Q'; for x with
2518 neither __int__ nor __long__, TypeError used to be raised (with a

Martin v. Löwis9fa5a282008-09-11 06:53:30 +00002715- Issue #3642: Suppress warning in obmalloc when size_t is larger than uint.
2716
Amaury Forgeot d'Arc05e34492008-09-10 22:04:45 +00002717- Issue #3743: In a few places, PY_FORMAT_SIZE_T was incorrectly used with
2718 PyString_FromFormat or PyErr_Format to display size_t values. The macro
2719 PY_FORMAT_SIZE_T is designed to select the correct format for the OS
2720 ``printf`` function, whereas PyString_FromFormat has an independent
2721 implementation and uses "%zd" on all platforms for size_t values.
2722 This makes a difference on win64, where ``printf`` needs "%Id" to display
2723 64bit values.
2724
Benjamin Peterson97179b02008-09-09 20:55:01 +00002725- Issue #3634: _weakref.ref(Exception).__init__() gave invalid return value on

2729 object; previously an int would be returned for small values. the __long__
2730 method is allowed to return either an int or a long, but the behaviour of
2731 float objects should not change to respect backward compatibility.
2732
Amaury Forgeot d'Arc3571fbf2008-09-01 19:52:00 +00002733- Issue #3751: str.rpartition would perform a left-partition when called with
2734 a unicode argument.

Vinay Sajip35e3b032008-09-01 14:33:59 +00002739 PyArg_ParseTuple and friends, which occurred when the argument for "s*"
Antoine Pitroud4ae97b2008-08-29 18:39:48 +00002740 was correctly parsed but parsing of subsequent arguments failed.
2741
Vinay Sajip35e3b032008-09-01 14:33:59 +00002742- Issue #2534: speed up isinstance() and issubclass() by 50-70%, so as to
Antoine Pitrou0668c622008-08-26 22:42:08 +00002743 match Python 2.5 speed despite the __instancecheck__ / __subclasscheck__
2744 mechanism. In the process, fix a bug where isinstance() and issubclass(),
2745 when given a tuple of classes as second argument, were looking up
2746 __instancecheck__ / __subclasscheck__ on the tuple rather than on each
2747 type object.
2748
Neal Norwitz18aa3882008-08-24 05:04:52 +00002749- Fix crashes on memory allocation failure found with failmalloc.
2750
2751- Fix memory leaks found with valgrind and update suppressions file.
2752
2753- Fix compiler warnings in opt mode which would lead to invalid memory reads.

2818 warnings.catch_warnings() along with some API cleanup. Expanding the tests
2819 for catch_warnings() also led to an improvement in the raising of a

2892-----------------
2893
Guido van Rossumf8402962008-08-20 15:01:50 +00002894- Issue #1878: Remove Py_TPFLAGS_HAVE_VERSION_TAG from
2895 Py_TPFLAGS_DEFAULT when not building the core. This means 3rd party
2896 extensions do not automatically benefit from the class attribute
2897 cache; they will have to explicitly add Py_TPFLAGS_HAVE_VERSION_TAG
2898 to their tp_flags field if they care. This is a backwards
2899 compatibility feature; in 3.0, all types will use the cache by
2900 default.
2901
Benjamin Petersonf647dc12008-08-20 01:27:30 +00002902- Keyword arguments can now follow starred arguments. (``f(a, *args,
2903 keyword=23)`` is now valid syntax.)
2904
Thomas Heller0ad5ae02008-08-19 19:25:04 +00002905- ctypes function pointers that are COM methods have a boolean True
2906 value again.
2907
Martin v. Löwisf91d46a2008-08-12 14:49:50 +00002908- Issue #3139: Make buffer-interface thread-safe wrt. PyArg_ParseTuple,
2909 by denying s# to parse objects that have a releasebuffer procedure,
2910 and introducing s*.
2911
Georg Brandl1e13ea92008-08-11 09:07:59 +00002912- Issue #3537: Fix an assertion failure when an empty but presized dict
2913 object was stored in the freelist.

Mark Dickinsonb6467572008-08-04 21:30:09 +00002915- Issue #1481296: Make long(float('nan')) and int(float('nan')) raise
2916 ValueError consistently across platforms.
2917
Amaury Forgeot d'Arc39fd6722008-07-31 21:28:03 +00002918- Issue #3479: On platforms where sizeof(int) is smaller than sizeof(long)
2919 (64bit Unix, for example), unichr() would truncate its argument and return
2920 u'\x00' for unichr(2**32). Now it properly raises an OverflowError.
2921
Neal Norwitze7d8be82008-07-31 17:17:14 +00002922- Apply security patches from Apple.
2923
Amaury Forgeot d'Arc246daed2008-07-31 00:42:16 +00002924- Issue #2542: Now that issubclass() may call arbitrary code, ensure that

Antoine Pitrou92f82162008-07-25 22:22:08 +00002927- Issue #1819: function calls with several named parameters are now on
2928 average 35% faster (as measured by pybench).
2929
Amaury Forgeot d'Arce4921fe2008-07-21 22:00:38 +00002930- Issue #2378: An unexpected UnboundLocalError or NameError could appear when
2931 the python debugger steps into a class statement: the free variables (local
2932 variables defined in an outer scope) would be deleted from the outer scope.
2933
Gregory P. Smith0470bab2008-07-22 04:46:32 +00002934- Issue #2620: Overflow checking when allocating or reallocating memory
2935 was not always being done properly in some python types and extension
2936 modules. PyMem_MALLOC, PyMem_REALLOC, PyMem_NEW and PyMem_RESIZE have
2937 all been updated to perform better checks and places in the code that
2938 would previously leak memory on the error path when such an allocation
2939 failed have been fixed.

2945
Benjamin Petersone977ad42008-08-20 01:42:01 +00002946- The methods ``is_in_tuple()``, ``is_vararg()``, and ``is_keywordarg()`` of
2947 symtable.Symbol have been deprecated for removal in 3.0 and the next release.
2948
Amaury Forgeot d'Arc351ffb82008-08-18 19:23:47 +00002949- Issue #2234: distutils failed for some versions of the cygwin compiler. The
2950 version reported by these tools does not necessarily follow the python
2951 version numbering scheme, so the module is less strict when parsing it.
2952
Nick Coghlanf70385a2008-08-18 12:42:46 +00002953- Issue #2235: Added Py3k warnings for types which will become unhashable
2954 under the stricter __hash__ inheritance rules in 3.0. Several types
2955 which did not meet the rules for hash invariants and were already
2956 unhashable in 3.0 have now been explicitly flagged as unhashable in
2957 2.6 as well (collections.Mapping, collections.Set, unittest.TestSuite,
2958 xml.dom.minidom.NamedNodeMap, numbers.Number, UserList.UserList)
2959
Brett Cannon88f801d2008-08-18 00:46:22 +00002960- Update __all__ for cookielib, csv, os, urllib2, and weakref to include things
2961 imported into the module but exposed as part of the module's API.
2962

2970 by using 's*' instead of 't#'.
2971
Mark Dickinson3e4caeb2009-02-21 20:27:01 +00002972- Issue #2222: Fixed reference leak when occurred os.rename()

2982 after a 302 response in the case of not going through a proxy.
2983
Antoine Pitroub90a8be2008-08-15 21:03:21 +00002984- Issue #2676: in the email package, content-type parsing was hanging on
2985 pathological input because of quadratic or exponential behaviour of a
2986 regular expression.
2987
Antoine Pitrou11ec65d2008-08-14 21:04:30 +00002988- Issue #3476: binary buffered reading through the new "io" library is now
2989 thread-safe.
2990
Brett Cannonbf3157b2008-08-14 05:00:03 +00002991- Silence the DeprecationWarning of rfc822 when it is imported by mimetools
2992 since mimetools itself is deprecated. Because modules are cached, all
2993 subsequent imports of rfc822 will not raise a visible DeprecationWarning.
2994
Antoine Pitrou9fcd4b32008-08-11 17:21:36 +00002995- Issue #3134: shutil referenced undefined WindowsError symbol.

Brett Cannon83e81842008-08-09 23:30:55 +00003000- Copied the implementation of reduce() to _functools.reduce() to have a
3001 version that did not raise a DeprecationWarning under -3.
3002
Antoine Pitrou76b8bee2008-08-09 17:27:23 +00003003- Issue #3205: When iterating over a BZ2File fails allocating memory, raise
3004 a MemoryError rather than silently stop the iteration.
3005
Guido van Rossum59ce9012008-08-09 14:55:34 +00003006- Issue #3487: sre "bytecode" validator. Passing invalid "re-bytecode"
3007 to _sre.compile() will now be rejected. This should not affect anybody
3008 since the re.compile() function never generates invalid re-bytecode.
3009
Skip Montanaroa032bf42008-08-08 22:52:51 +00003010- Issue #3436: Make csv.DictReader's fieldnames attribute a property so that
3011 upon first access it can be automatically initialized from the csv file if
3012 it wasn't initialized during instantiation.
3013
Brett Cannon3aa2a492008-08-06 22:28:09 +00003014- Issue #2338: Create imp.reload() to help with transitioning to Python 3.0 as
3015 the reload() built-in has been removed.
3016
Brett Cannon7e30b672008-08-04 21:52:25 +00003017- Changed code in the following modules/packages to remove warnings raised
Brett Cannonc1b76e42008-08-09 23:06:16 +00003018 while running under the ``-3`` flag: aifc, asynchat, asyncore, bdb, bsddb,

3026 raised an AttributeError.
3027
Benjamin Peterson01a24322008-07-28 23:35:27 +00003028- Issue #2523: Fix quadratic behaviour when read()ing a binary file without
Antoine Pitroude781a42008-08-09 12:43:23 +00003029 asking for a specific length. This problem only affected files opened
3030 using the new "io" module, not the built-in open() function.
Benjamin Peterson01a24322008-07-28 23:35:27 +00003031

3054
Antoine Pitrou5fdfa3e2008-07-25 19:42:26 +00003055- Issue #3394: zipfile.writestr sets external attributes when passed a
3056 file name rather than a ZipInfo instance, so files are extracted with
3057 mode 0600 rather than 000 under Unix.
3058
Gregory P. Smitha36f8fe2008-08-04 00:13:29 +00003059- Issue #1857: subprocess.Popen.poll gained an additional _deadstate keyword
3060 argument in python 2.5, this broke code that subclassed Popen to include its
3061 own poll method. Fixed my moving _deadstate to an _internal_poll method.

Nick Coghlan6e8fef02008-08-18 13:14:22 +00003071- Issue #2235: the C API function PyObject_HashNotImplemented and its
3072 interaction with the tp_hash slot (added in 2.6b2) are now documented
3073
Nick Coghlan2a0c2b12008-08-04 12:47:17 +00003074- Issue #643841: The language reference now provides more detailed
3075 coverage of the lookup process for special methods. The disclaimers
3076 regarding lack of coverage of new-style classes have also been
3077 removed, since the coverage is now fairly reasonable.

3081================================
3082
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00003083*Release date: 17-Jul-2008*
3084
Raymond Hettingere3ae6552008-06-20 04:18:15 +00003085Core and Builtins
3086-----------------
3087
Georg Brandl3e483f62008-07-16 22:57:41 +00003088- Issue #3156: Fix inconsistent behavior of the bytearray type: all
3089 its methods now allow for items objects that can be converted to
3090 an integer using operator.index().
3091
Mark Dickinson64b7e502008-07-16 09:40:03 +00003092- Issue #3360: Fix incorrect parsing of '020000000000.0', which
3093 produced a ValueError instead of giving the correct float.
3094
Eric Smitha5fa5a22008-07-16 00:11:49 +00003095- Issue #3083: Add alternate (#) formatting for bin, oct, hex output
3096 for str.format(). This adds the prefix 0b, 0o, or 0x, respectively.
3097
Mark Dickinson7103aa42008-07-15 19:08:33 +00003098- Issue #3008: the float type has a new instance method 'float.hex'
3099 and a new class method 'float.fromhex' to convert floating-point
3100 numbers to and from hexadecimal strings, respectively.
3101
Nick Coghlan6d6bd442008-07-15 15:40:22 +00003102- Issue #2235: __hash__ is once again inherited by default. To allow
3103 collections.Hashable to remain meaningful in the presence of the
3104 default hash implementation (object.__hash__), it is now possible
3105 to explicit block inheritance of hash by setting __hash__=None at
3106 the Python level, or tp_hash=PyObject_HashNotImplemented at the C
3107 level.
3108
Nick Coghlanb028f502008-07-13 14:52:36 +00003109- Issue #3221: Issue a RuntimeWarning instead of raising SystemError if
3110 the parent module cannot be found while performing an absolute import.
3111 This means that an incorrectly defined __package__ attribute will
3112 now only prevent relative imports in that module rather than causing
3113 all imports from that module to fail.
3114
Nick Coghlan14ff9942008-07-08 14:21:42 +00003115- Issue #2517: Allow unicode messages in Exceptions again by correctly
3116 bypassing the instance dictionary when looking up __unicode__ on
3117 new-style classes.
3118
Amaury Forgeot d'Arcbdd941f2008-07-01 20:38:04 +00003119- Issue #3242: Fix a crash inside the print statement, if sys.stdout is
3120 set to a custom object whose write() method happens to install
3121 another file in sys.stdout.
3122
Amaury Forgeot d'Arc1f40c8a2008-06-30 22:42:40 +00003123- Issue #3088: Corrected a race condition in classes derived from
3124 threading.local: the first member set by a thread could be saved in
3125 another thread's dictionary.
3126
Mark Dickinson1ec2fcd2008-06-20 14:53:43 +00003127- Issue #3004: Minor change to slice.indices(): the start and stop
3128 arguments are now treated identically, making the behaviour easier
3129 to describe and understand. For example, slice(None, -10,
3130 1).indices(9) now returns (0, 0, 1) instead of (0, -1, 1), and
3131 slice(None, 10, -1).indices(10) returns (9, 9, -1) instead of (9,
3132 10, -1).
3133
Georg Brandl278fc502008-07-19 12:46:12 +00003134- Issue #3219: Calling a function with repeated keyword arguments,
3135 f(a=2, a=23), would not cause a syntax error. This was a regression
3136 from 2.4 caused by the switch to the new compiler.
Benjamin Peterson175e4d92008-07-01 19:34:52 +00003137
Georg Brandl278fc502008-07-19 12:46:12 +00003138- Issue #2862: Make int and float freelist management consistent with
3139 other freelists. Changes their CompactFreeList apis into
3140 ClearFreeList apis and calls them via gc.collect().
Gregory P. Smith2fe77062008-07-06 03:35:58 +00003141

3143-------
3144
Thomas Heller57adf222008-08-14 19:10:48 +00003145- Issue #3554: ctypes.string_at and ctypes.wstring_at did call Python
3146 api functions without holding the GIL, which could lead to a fatal
3147 error when they failed.
3148
Martin v. Löwisaabf4042008-08-02 07:20:25 +00003149- Issue #799428: Fix Tkinter.Misc._nametowidget to unwrap Tcl command objects.

Jesse Noller13e9d582008-07-16 14:32:36 +00003157- Issue #3125: Remove copy_reg in multiprocessing and replace it with
3158 ForkingPickler.register() to resolve conflict with ctypes.
3159
Vinay Sajip51e65192008-07-18 09:01:10 +00003160- Issue #3090: Fixed ARCHFLAGS parsing on OS/X
Jesse Noller13e9d582008-07-16 14:32:36 +00003161
Thomas Heller880f5292008-07-15 19:39:38 +00003162- Issue #3313: Fixed a crash when a failed dlopen() call does not set
3163 a valid dlerror() message.
3164
Thomas Heller2bad6572008-07-15 17:19:50 +00003165- Issue #3258: Fixed a crash when a ctypes POINTER type to an
3166 incomplete structure was created.
3167

3171
Andrew M. Kuchlingcc3f2b12008-07-10 14:43:31 +00003172- Issue #3301: Bisect module behaved badly when lo was negative.
Raymond Hettinger3cd1e422008-07-10 14:03:19 +00003173
Amaury Forgeot d'Arc0f7cddc2008-07-06 21:34:39 +00003174- Issue #839496: SimpleHTTPServer used to open text files in text mode. This is
3175 both unnecessary (HTTP allows text content to be sent in several forms) and
Andrew M. Kuchlingcc3f2b12008-07-10 14:43:31 +00003176 wrong because the actual transmitted size could differ from the
Amaury Forgeot d'Arc0f7cddc2008-07-06 21:34:39 +00003177 content-length. The problem had been corrected in the 2.4 branch, but never
3178 merged into trunk.
3179
Georg Brandle78fbcc2008-07-05 10:13:36 +00003180- Issue #2663: add filtering capability to shutil.copytree().

Andrew M. Kuchlingcc3f2b12008-07-10 14:43:31 +00003191 when completed.
Facundo Batista66c52772008-07-02 16:52:55 +00003192
Nick Coghlanc060b0e2008-07-02 13:09:19 +00003193- Issue #3190: Pydoc now hides the automatic module attribute __package__ (the
3194 handling is now the same as that of other special attributes like __name__).
3195
Brett Cannon8bb8fa52008-07-02 01:57:08 +00003196- Issue #2885 (partial): The urllib.urlopen() function has been deprecated for
3197 removal in Python 3.0 in favor of urllib2.urlopen().

Georg Brandl5cc774e2008-06-11 20:28:06 +00003586 PPC64 and x86_64 support in one binary).
Ronald Oussoren5640ce22008-06-05 12:58:24 +00003587
3588 This is controlled by the configure argument ``--with-universal-archs``:
3589
3590 - ``--with-universal-archs=all``: install 4-way universal
3591
3592 - ``--with-universal-archs=32-bit``: install 2-way universal, 32-bit (the default)
3593
3594 - ``--with-universal-archs=64-bit``: install 2-way universal, 64-bit
3595
3596 This option should be used in combination with ``--enable-universalsdk=``.
3597
3598 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 +00003648- Issue #1631171: Re-implement the 'warnings' module in C (the
3649 original Python code has been kept as backup). This will allow for
3650 using the 'warning's machinery in such places as the parser where
3651 use of pure Python code is not possible. Both the ``showarning()``
3652 and ``formatwarning()`` gain an optional 'line' argument which is
3653 not called by default for backwards-compatibility reasons. Setting
3654 ``warnings.showwarning()`` to an implementation that lacks support
3655 for the ``line`` argument will raise a DeprecationWarning.

Georg Brandl3ee81df2008-05-17 18:14:43 +00003718- Issue #2550: The approach used by client/server code for obtaining
3719 ports to listen on in network-oriented tests has been refined in an
3720 effort to facilitate running multiple instances of the entire
3721 regression test suite in parallel without issue.
3722 test_support.bind_port() has been fixed such that it will always
3723 return a unique port -- which wasn't always the case with the
3724 previous implementation, especially if socket options had been set
3725 that affected address reuse (i.e. SO_REUSEADDR, SO_REUSEPORT). The
3726 new implementation of bind_port() will actually raise an exception
3727 if it is passed an AF_INET/SOCK_STREAM socket with either the
3728 SO_REUSEADDR or SO_REUSEPORT socket option set. Furthermore, if
3729 available, bind_port() will set the SO_EXCLUSIVEADDRUSE option on
3730 the socket it's been passed. This currently only applies to
3731 Windows. This option prevents any other sockets from binding to the
3732 host/port we've bound to, thus removing the possibility of the
3733 'non-deterministic' behaviour, as Microsoft puts it, that occurs
3734 when a second SOCK_STREAM socket binds and accepts to a host/port
3735 that's already been bound by another socket. The optional preferred
3736 port parameter to bind_port() has been removed. Under no
3737 circumstances should tests be hard coding ports!
3738
3739 test_support.find_unused_port() has also been introduced, which will
3740 pass a temporary socket object to bind_port() in order to obtain an
3741 unused port. The temporary socket object is then closed and
3742 deleted, and the port is returned. This method should only be used
3743 for obtaining an unused port in order to pass to an external program
3744 (i.e. the -accept [port] argument to openssl's s_server mode) or as
3745 a parameter to a server-oriented class that doesn't give you direct
3746 access to the underlying socket used.
3747
3748 Finally, test_support.HOST has been introduced, which should be used
3749 for the host argument of any relevant socket calls (i.e. bind and
3750 connect).
Trent Nelsone41b0062008-04-08 23:47:30 +00003751
3752 The following tests were updated to following the new conventions:
Georg Brandl3ee81df2008-05-17 18:14:43 +00003753 test_socket, test_smtplib, test_asyncore, test_ssl, test_httplib,

3755 test_asynchat and test_socket_ssl.
3756
Georg Brandl3ee81df2008-05-17 18:14:43 +00003757 It is now possible for multiple instances of the regression test
3758 suite to run in parallel without issue.

Fred Drakea8ee94b2008-03-01 02:45:07 +00004027- Issue #2051: pyc and pyo files are no longer created with permission
Barry Warsaw52973612008-03-01 02:23:38 +00004028 644. The mode is now inherited from the py file.
Christian Heimes40346852008-02-23 17:52:07 +00004029
Georg Brandlad61bc82008-02-23 15:11:18 +00004030- Issue #2067: file.__exit__() now calls subclasses' close() method.
4031
4032- Patch #1759: Backport of PEP 3129 class decorators.
Christian Heimes5224d282008-02-23 15:01:05 +00004033
Vinay Sajipb7edfc42008-04-02 21:10:23 +00004034- Issue #1881: An internal parser limit has been increased. Also see
Facundo Batistafc2d0102008-02-23 12:01:13 +00004035 issue 215555 for a discussion.
4036
Eric Smitha73fbe72008-02-23 03:09:44 +00004037- Added the future_builtins module, which contains hex() and oct().
4038 These are the PEP 3127 version of these functions, designed to be
4039 compatible with the hex() and oct() builtins from Python 3.0. They
4040 differ slightly in their output formats from the existing, unchanged
4041 Python 2.6 builtins. The expected usage of the future_builtins
4042 module is:
4043 from future_builtins import hex, oct
4044
Eric Smith7ef40bf2008-02-20 23:34:22 +00004045- Issue #1600: Modifed PyOS_ascii_formatd to use at most 2 digit
4046 exponents for exponents with absolute value < 100. Follows C99
4047 standard. This is a change on Windows, which would use 3 digits.
4048 Also, added 'n' to the formats that PyOS_ascii_formatd understands,
4049 so that any alterations it does to the resulting string will be
4050 available in stringlib/formatter.h (for float.__format__).
4051
Eric Smith5a3c1352008-02-19 13:21:56 +00004052- Implemented PEP 3101, Advanced String Formatting. This adds a new
4053 builtin format(); a format() method for str and unicode; a
4054 __format__() method to object, str, unicode, int, long, float, and
4055 datetime; the class string.Formatter; and the C API
4056 PyObject_Format().
4057
Georg Brandl3ee81df2008-05-17 18:14:43 +00004058- Fixed several potential crashes, all caused by specially crafted
4059 __del__ methods exploiting objects in temporarily inconsistent
4060 state.
Amaury Forgeot d'Arc632fad32008-02-16 20:55:24 +00004061
Vinay Sajipb7edfc42008-04-02 21:10:23 +00004062- Issue #2115: Important speedup in setting __slot__ attributes. Also
Georg Brandl3ee81df2008-05-17 18:14:43 +00004063 prevent a possible crash: an Abstract Base Class would try to access
4064 a slot on a registered virtual subclass.
Amaury Forgeot d'Arc60d6c7f2008-02-15 21:22:45 +00004065
Georg Brandl3ee81df2008-05-17 18:14:43 +00004066- Fixed repr() and str() of complex numbers with infinity or nan as
4067 real or imaginary part.
Christian Heimes2f0da532008-02-15 06:57:08 +00004068
Georg Brandl3ee81df2008-05-17 18:14:43 +00004069- Clear all free lists during a gc.collect() of the highest generation
4070 in order to allow pymalloc to free more arenas. Python may give back
4071 memory to the OS earlier.
Christian Heimes3b718a72008-02-14 12:47:33 +00004072
Georg Brandl3ee81df2008-05-17 18:14:43 +00004073- Issue #2045: Fix an infinite recursion triggered when printing a
4074 subclass of collections.defaultdict, if its default_factory is set
4075 to a bound method.
Amaury Forgeot d'Arcb01aa432008-02-08 00:56:02 +00004076
Christian Heimesf75dbef2008-02-08 00:11:31 +00004077- Fixed a minor memory leak in dictobject.c. The content of the free
4078 list was not freed on interpreter shutdown.
4079
Georg Brandl21e99f42010-03-07 15:23:59 +00004080- Limit free list of method and built-in function objects to 256
Georg Brandl3ee81df2008-05-17 18:14:43 +00004081 entries each.
Christian Heimes6075a822008-02-06 12:44:34 +00004082
Georg Brandl3ee81df2008-05-17 18:14:43 +00004083- Patch #1953: Added ``sys._compact_freelists()`` and the C API
4084 functions ``PyInt_CompactFreeList`` and ``PyFloat_CompactFreeList``
Christian Heimes422051a2008-02-04 18:00:12 +00004085 to compact the internal free lists of pre-allocted ints and floats.
4086
Georg Brandl3ee81df2008-05-17 18:14:43 +00004087- Issue #1983: Fixed return type of fork(), fork1() and forkpty()
4088 calls. Python expected the return type int but the fork familie
4089 returns pi_t.
Christian Heimes951cc0f2008-01-31 23:08:23 +00004090
Georg Brandl3ee81df2008-05-17 18:14:43 +00004091- Issue #1678380: Fix a bug that identifies 0j and -0j when they
4092 appear in the same code unit.
Mark Dickinson105be772008-01-31 22:17:37 +00004093
Georg Brandl3ee81df2008-05-17 18:14:43 +00004094- Issue #2025: Add tuple.count() and tuple.index() methods to comply
4095 with the collections.Sequence API.
Raymond Hettinger5b07ebc2008-02-07 00:54:20 +00004096
Georg Brandl3ee81df2008-05-17 18:14:43 +00004097- Patch #1970 by Antoine Pitrou: Speedup unicode whitespace and
4098 linebreak detection
Christian Heimes4d4f2702008-01-30 11:32:37 +00004099
Georg Brandl3ee81df2008-05-17 18:14:43 +00004100- Added ``PyType_ClearCache()`` and ``sys._clear_type_cache`` to clear
4101 the internal lookup cache for ref leak tests.
Christian Heimes908caac2008-01-27 23:34:59 +00004102
Georg Brandl3ee81df2008-05-17 18:14:43 +00004103- Patch #1473257: generator objects gain a gi_code attribute. This is
4104 the same object as the func_code attribute of the function that
4105 produced the generator.
Georg Brandl0cdf9a32008-01-26 14:14:20 +00004106
Georg Brandl3ee81df2008-05-17 18:14:43 +00004107- Issue #1920: "while 0" statements were completely removed by the
4108 compiler, even in the presence of an "else" clause, which is
4109 supposed to be run when the condition is false. Now the compiler
4110 correctly emits bytecode for the "else" suite.
Amaury Forgeot d'Arc31eaafe2008-01-24 22:59:25 +00004111
Guido van Rossumeead05f2008-01-24 18:21:02 +00004112- A few crashers fixed: weakref_in_del.py (issue #1377858);
4113 loosing_dict_ref.py (issue #1303614, test67.py);
4114 borrowed_ref_[34].py (not in tracker).
4115
Vinay Sajipd7cf32e2008-01-24 12:43:33 +00004116- Issue #1069410: The "can't load dll" message box on Windows is
Christian Heimesb2302ba2008-01-23 17:15:06 +00004117 suppressed while an extension is loaded by calling SetErrorMode in
4118 dynload_win.c. The error is still reported properly.
4119
Georg Brandl3ee81df2008-05-17 18:14:43 +00004120- Issue #1915: Python compiles with --enable-unicode=no again. However
Christian Heimes082c9b02008-01-23 14:20:50 +00004121 several extension methods and modules do not work without unicode
4122 support.
4123
Georg Brandl26543b12008-01-21 18:36:51 +00004124- Issue #1882: when compiling code from a string, encoding cookies in the
4125 second line of code were not always recognized correctly.
4126
Georg Brandl14404b62008-01-19 19:27:05 +00004127- Issue #1679: "0x" was taken as a valid integer literal.
4128
Georg Brandl6caad7d2008-01-26 14:19:22 +00004129- Issue #1865: ``bytes`` as an alias for ``str`` and b"" as an alias "" were
Christian Heimes288e89a2008-01-18 18:24:07 +00004130 added.
4131
Christian Heimesc94e2b52008-01-14 04:13:37 +00004132- sys.float_info / PyFloat_GetInfo: The floating point information
4133 object was converted from a dict to a specialized structseq object.
4134
Georg Brandl3ee81df2008-05-17 18:14:43 +00004135- Patch #1816: Added sys.flags structseq. It exposes the status of
4136 most command line arguments and PYTHON* environment variables.
Christian Heimesf31b69f2008-01-14 03:42:48 +00004137
Georg Brandl3ee81df2008-05-17 18:14:43 +00004138- Objects/structseq.c: Implemented new structseq representation. The
4139 patch makes structseqs (e.g. the return value of os.stat) more
4140 readable.
Christian Heimes9c201962008-01-14 03:33:52 +00004141
Georg Brandl3ee81df2008-05-17 18:14:43 +00004142- Patch #1700288: added a type attribute cache that caches method
4143 accesses, resulting in speedups in heavily object-oriented code.
Amaury Forgeot d'Arce4c270c2008-01-14 00:29:41 +00004144
Neal Norwitz3fc15b82008-01-10 05:42:58 +00004145- Bug #1776: __import__() no longer accepts filenames on any platform.
4146 The first parameter to __import__() must be a valid module name.
Christian Heimes3403f152008-01-09 19:56:33 +00004147
Georg Brandlaed6c662008-01-07 17:25:53 +00004148- Patch #1668: renamed THREADDEBUG envvar to PYTHONTHREADDEBUG.
4149
Georg Brandl3ee81df2008-05-17 18:14:43 +00004150- Patch #602345: Add -B command line option, PYTHONDONTWRITEBYTECODE
4151 envvar and sys.dont_write_bytecode attribute. All these can be set
4152 to forbid Python to attempt to write compiled bytecode files.
Georg Brandl2da0fce2008-01-07 17:09:35 +00004153
Georg Brandl3ee81df2008-05-17 18:14:43 +00004154- Improve some exception messages when Windows fails to load an
4155 extension module. Now we get for example '%1 is not a valid Win32
4156 application' instead of 'error code 193'.
Amaury Forgeot d'Arce0b76952008-01-04 02:04:15 +00004157
Georg Brandl3ee81df2008-05-17 18:14:43 +00004158- Bug #1481296: Fixed long(float('nan')) != 0L.

Georg Brandl3ee81df2008-05-17 18:14:43 +00004160- Issue #1640: Added math.isinf(x), math.isnan(x) and math.copysign(x,
4161 y) functions.
Christian Heimese2ca4242008-01-03 20:23:15 +00004162
Christian Heimes0a8143f2007-12-18 23:22:54 +00004163- Issue #1635: Platform independent creation and representation of NaN
Georg Brandl3ee81df2008-05-17 18:14:43 +00004164 and INF. float("nan"), float("inf") and float("-inf") now work on
4165 every platform with IEEE 754 semantics.
Christian Heimes0a8143f2007-12-18 23:22:54 +00004166
Georg Brandl3ee81df2008-05-17 18:14:43 +00004167- Compiler now generates simpler and faster code for dictionary
4168 literals. The oparg for BUILD_MAP now indicates an estimated
4169 dictionary size. There is a new opcode, STORE_MAP, for adding
4170 entries to the dictionary.
Raymond Hettingerfd7ed402007-12-18 21:24:09 +00004171
Georg Brandl3ee81df2008-05-17 18:14:43 +00004172- Issue #1638: %zd configure test fails on Linux.

Georg Brandl3ee81df2008-05-17 18:14:43 +00004177- Issue #1538: Avoid copying string in split/rsplit if the split char
4178 is not found.
Skip Montanaro26015492007-12-08 15:33:24 +00004179
Andrew M. Kuchling395fe442007-12-05 13:27:20 +00004180- Issue #1553: An erroneous __length_hint__ can make list() raise a
Christian Heimes7cc1c6f2007-12-05 12:52:34 +00004181 SystemError.
4182
Nick Coghlanef01d822007-12-03 12:55:17 +00004183- PEP 366: Allow explicit relative imports when executing modules
4184 inside packages with the -m switch via a new module level
4185 __package__ attribute.
4186
Georg Brandl3ee81df2008-05-17 18:14:43 +00004187- Issue #1402: Fix a crash on exit, when another thread is still
4188 running, and if the deallocation of its frames somehow calls the
4189 PyGILState_Ensure() / PyGILState_Release() functions.
Amaury Forgeot d'Arcbe49a902007-11-30 20:37:22 +00004190

Amaury Forgeot d'Arcce7d10c2007-11-24 13:44:17 +00004194 attribute of an empty cell object.
4195
Georg Brandl3ee81df2008-05-17 18:14:43 +00004196- Issue #1460: The utf-7 incremental decoder did not accept truncated
4197 input. It now correctly saves its state between chunks of data.
Amaury Forgeot d'Arcf57375a2007-11-21 01:38:26 +00004198
Georg Brandl3ee81df2008-05-17 18:14:43 +00004199- Patch #1739468: Directories and zipfiles containing a __main__.py
4200 file can now be directly executed by passing their name to the
4201 interpreter. The directory/zipfile is automatically inserted as the
4202 first entry in sys.path.
Nick Coghlan327a39b2007-11-18 11:56:28 +00004203
Georg Brandl3ee81df2008-05-17 18:14:43 +00004204- Issue #1265: Fix a problem with sys.settrace, if the tracing
4205 function uses a generator expression when at the same time the
4206 executed code is closing a paused generator.
Amaury Forgeot d'Arc0d75f092007-11-13 21:54:28 +00004207
Raymond Hettinger1760c8a2007-11-08 02:52:43 +00004208- sets and frozensets now have an isdisjoint() method.
4209
Raymond Hettinger3f8caa32007-10-24 01:28:33 +00004210- optimize the performance of builtin.sum().
4211
Neal Norwitz44f326e2007-10-05 05:29:17 +00004212- Fix warnings found by the new version of the Coverity checker.
4213
Georg Brandl21e99f42010-03-07 15:23:59 +00004214- The enumerate() built-in function is no longer bounded to sequences
Georg Brandl3ee81df2008-05-17 18:14:43 +00004215 smaller than LONG_MAX. Formerly, it raised an OverflowError. Now,
4216 automatically shifts from ints to longs.
Raymond Hettinger8f669372007-10-03 21:18:11 +00004217
Georg Brandl3ee81df2008-05-17 18:14:43 +00004218- Issue #1686386: Tuple's tp_repr did not take into account the
4219 possibility of having a self-referential tuple, which is possible
4220 from C code. Nor did object's tp_str consider that a type's tp_str
4221 could do something that could lead to an inifinite recursion.
4222 Py_ReprEnter() and Py_EnterRecursiveCall(), respectively, fixed the
4223 issues.
Brett Cannon0b14f242007-09-30 19:45:10 +00004224
Georg Brandl3ee81df2008-05-17 18:14:43 +00004225- Issue #1164: It was possible to trigger deadlock when using the
4226 'print' statement to write to a file since the GIL was not released
4227 as needed. Now PyObject_Print() does the right thing along with
4228 various tp_print implementations of the built-in types and those in
4229 the collections module.
Brett Cannon01531592007-09-17 03:28:34 +00004230
Georg Brandl3ee81df2008-05-17 18:14:43 +00004231- Issue #1147: Exceptions were directly allowing string exceptions in
4232 their throw() method even though string exceptions no longer
4233 allowed.
Brett Cannon4c20bc42007-09-11 21:02:28 +00004234
Georg Brandl3ee81df2008-05-17 18:14:43 +00004235- Issue #1096: Prevent a segfault from getting the repr of a very

Brett Cannon1e534b52007-09-07 04:18:30 +00004238- Issue #1202533: Fix infinite recursion calls triggered by calls to
Georg Brandl3ee81df2008-05-17 18:14:43 +00004239 PyObject_Call() never calling back out to Python code to trigger
4240 recursion depth updates/checks. Required the creation of a static
4241 RuntimeError instance in case normalizing an exception put the
4242 recursion check value past its limit. Fixes crashers
4243 infinite_rec_(1|2|4|5).py.
Brett Cannon1e534b52007-09-07 04:18:30 +00004244
Georg Brandl3ee81df2008-05-17 18:14:43 +00004245- Patch #1031213: Decode source line in SyntaxErrors back to its

Neal Norwitz0ac60192007-05-27 04:08:54 +00004258- Add new attribute names for function objects. All the func_* become
Georg Brandl3ee81df2008-05-17 18:14:43 +00004259 __*__ attributes. (Some already existed, e.g., __doc__ and
4260 __name__.)
Neal Norwitz0ac60192007-05-27 04:08:54 +00004261
Neal Norwitz8b2bfbc2007-05-23 06:35:32 +00004262- Add -3 option to the interpreter to warn about features that are
4263 deprecated and will be changed/removed in Python 3.0.
4264

Collin Winter62903052007-05-18 23:11:24 +00004268- except clauses may now be spelled either "except E, target:" or
Georg Brandl3ee81df2008-05-17 18:14:43 +00004269 "except E as target:". This is to provide forwards compatibility
4270 with Python 3.0.
Collin Winter62903052007-05-18 23:11:24 +00004271
Brett Cannon229cee22007-05-05 01:34:02 +00004272- Deprecate BaseException.message as per PEP 352.
4273
Georg Brandl3ee81df2008-05-17 18:14:43 +00004274- Issue #1303614: don't expose object's __dict__ when the dict is
Georg Brandl21e99f42010-03-07 15:23:59 +00004275 inherited from a built-in base.
Armin Rigo9790a272007-05-02 19:23:31 +00004276
Vinay Sajip8549ce32007-05-06 17:53:37 +00004277- When __slots__ are set to a unicode string, make it work the same as
Neal Norwitzcbd9ee62007-04-14 05:25:50 +00004278 setting a plain string, ie don't expand to single letter identifiers.
4279
Raymond Hettinger13936692007-04-11 18:40:58 +00004280- Request #1191699: Slices can now be pickled.

4290
Guido van Rossum143b5642007-03-23 04:58:42 +00004291- Bug #1683368: The object.__init__() and object.__new__() methods are
4292 now stricter in rejecting excess arguments. The only time when
4293 either allows excess arguments is when it is not overridden and the
4294 other one is. For backwards compatibility, when both are
4295 overridden, it is a deprecation warning (for now; maybe a Py3k
Guido van Rossum234b1ff2007-03-23 19:39:01 +00004296 warning later). Also, type.__init__() insists on the same signature
4297 as supported by type.__new__().
Guido van Rossum143b5642007-03-23 04:58:42 +00004298
Georg Brandl3ee81df2008-05-17 18:14:43 +00004299- Patch #1675423: PyComplex_AsCComplex() now tries to convert an
4300 object to complex using its __complex__() method before falling back
4301 to the __float__() method. Therefore, the functions in the cmath
4302 module now can operate on objects that define a __complex__()
4303 method.

4320
Georg Brandl7b9c5552007-03-12 14:30:05 +00004321- Bug #1678647: write a newline after printing an exception in any
4322 case, even when converting the value to a string failed.
4323
Georg Brandl871f1bc2007-03-12 13:17:36 +00004324- The dir() function has been extended to call the __dir__() method on
Georg Brandl3ee81df2008-05-17 18:14:43 +00004325 its argument, if it exists. If not, it will work like before. This
4326 allows customizing the output of dir() in the presence of a
4327 __getattr__().

Collin Winter276887b2007-03-12 16:11:39 +00004329- Patch #922167: Python no longer segfaults when faced with infinitely
4330 self-recursive reload() calls (as reported by bug #742342).

4337 raising a ValueError.
Collin Wintere38051d2007-03-09 20:33:07 +00004338
Georg Brandlaa2321b2007-03-07 00:40:28 +00004339- Patch #703779: unset __file__ in __main__ after running a file. This
Georg Brandl3ee81df2008-05-17 18:14:43 +00004340 makes the filenames the warning module prints much more sensible
4341 when a PYTHONSTARTUP file is used.
Georg Brandlaa2321b2007-03-07 00:40:28 +00004342

Georg Brandl0fca97a2007-03-05 22:28:08 +00004354- Patch #1674228: when assigning a slice (old-style), check for the
4355 sq_ass_slice instead of the sq_slice slot.
4356
Georg Brandl3ee81df2008-05-17 18:14:43 +00004357- When printing an unraisable error, don't print exceptions. before
4358 the name. This duplicates the behavior whening normally printing
4359 exceptions.

4368 created a weakref on itself during a __del__ call for new-style
4369 classes (classic classes still have the bug).

4410 embedded in the string to convert.
4411
Georg Brandl846f73a2006-10-08 07:11:54 +00004412- Bug #1569998: break inside a try statement (outside a loop) is now

Georg Brandl3ee81df2008-05-17 18:14:43 +00004460 generator expressions (x for x, in ... ) works again. Fixing this
4461 problem required changing the .pyc magic number. This means that
4462 .pyc files generated before 2.5c2 will be regenerated.

5267 members).
Walter Dörwald84a3efe2007-06-13 16:57:12 +00005268
Georg Brandl3ee81df2008-05-17 18:14:43 +00005269- Issue #829951: In the smtplib module, SMTP.starttls() now complies
5270 with RFC 3207 and forgets any knowledge obtained from the server not
5271 obtained from the TLS negotiation itself. Patch contributed by Bill
5272 Fenner.
Gregory P. Smith2b3ba582008-01-17 08:03:17 +00005273
Georg Brandl3ee81df2008-05-17 18:14:43 +00005274- Issue #1339: The smtplib.SMTP class has been refactored a bit such
Gregory P. Smithbde4ae42008-01-17 08:35:49 +00005275 that the SMTP.starttls() caller no longer needs to call ehlo()
5276 beforehand. SMTP.starttls() now raises an exception of the server
Georg Brandl3ee81df2008-05-17 18:14:43 +00005277 does not claim to support starttls. Adds the
5278 SMTP.ehlo_or_helo_if_needed() method. Patch contributed by Bill

5359 complex, tuple, list, dict, set, and frozenset. Formerly, it would
5360 silently miscode subclasses of those types. Now, it raises a
5361 ValueError instead.
Raymond Hettinger12e94202007-11-07 01:13:09 +00005362

Georg Brandl3ee81df2008-05-17 18:14:43 +00005377 time so that opening a database previously created with the DB_DUP
5378 or DB_DUPSORT flag set will keep the proper behavior on subsequent
5379 opens. Specifically: dictionary assignment to a DB object will
5380 replace all values for a given key when the database allows
5381 duplicate values. DB users should use DB.put(k, v) when they want
5382 to store duplicates; not DB[k] = v.
Gregory P. Smithec10a4a2007-11-05 02:32:26 +00005383

5389 characters with ASCII value less than 32. Also, it correctly quotes
5390 dots only if they occur on a single line, as opposed to the previous
5391 behavior of quoting dots if they are the second character of any
5392 line.
Georg Brandl4aef7272007-03-13 22:49:43 +00005393

5730 PyLong_FromSsize_t public functions.
Georg Brandl6caad7d2008-01-26 14:19:22 +00005731
5732- Patch #1720595: add T_BOOL to the range of structmember types.
5733
5734- Issue #1534: Added ``PyFloat_GetMax()``, ``PyFloat_GetMin()`` and
5735 ``PyFloat_GetInfo()`` to the float API.
5736
Georg Brandl3ee81df2008-05-17 18:14:43 +00005737- Issue #1521: On 64bit platforms, using PyArgs_ParseTuple with the t#
5738 of w# format code incorrectly truncated the length to an int, even
5739 when PY_SSIZE_T_CLEAN is set. The str.decode method used to return
5740 incorrect results with huge strings.
Georg Brandl6caad7d2008-01-26 14:19:22 +00005741
Georg Brandl3ee81df2008-05-17 18:14:43 +00005742- Issue #1629: Renamed Py_Size, Py_Type and Py_Refcnt to Py_SIZE,
5743 Py_TYPE and Py_REFCNT.

Georg Brandl3ee81df2008-05-17 18:14:43 +00005745- PEP 3123: Provide forward compatibility with Python 3.0, while
5746 keeping backwards compatibility. Add Py_Refcnt, Py_Type, Py_Size,
5747 and PyVarObject_HEAD_INIT.
Georg Brandl6caad7d2008-01-26 14:19:22 +00005748
Georg Brandl3ee81df2008-05-17 18:14:43 +00005749- Py_ssize_t fields work in structmember when HAVE_LONG_LONG is not
5750 defined.
Georg Brandl6caad7d2008-01-26 14:19:22 +00005751
5752- Patch #1733960: Allow T_LONGLONG to accept ints.
5753
5754- T_PYSSIZET can now be used in PyMemberDef lists for Py_ssize_t members.
5755
Christian Heimes000a0742008-01-03 22:16:32 +00005756- Added a new API function ``PyImport_ImportModuleNoBlock``.

Georg Brandl6caad7d2008-01-26 14:19:22 +00005758- Bug #1637022: Prefix AST symbols with _Py_.
5759
5760- Fix some leftovers from the conversion from int to Py_ssize_t
5761 (relevant to strings and sequences of more than 2**31 items).
5762
5763- Make _PyGILState_NoteThreadState() static, it was not used anywhere
5764 outside of pystate.c and should not be necessary.
5765
Georg Brandl3ee81df2008-05-17 18:14:43 +00005766- ``PyImport_Import`` and ``PyImport_ImportModule`` now always do
5767 absolute imports. In earlier versions they might have used relative
5768 imports under some conditions.
Christian Heimes000a0742008-01-03 22:16:32 +00005769
Georg Brandl3ee81df2008-05-17 18:14:43 +00005770- Added case insensitive comparison methods ``PyOS_stricmp(char*,
5771 char*)`` and ``PyOS_strnicmp(char*, char*, Py_ssize_t)``.
Christian Heimes000a0742008-01-03 22:16:32 +00005772
Georg Brandl3ee81df2008-05-17 18:14:43 +00005773- Bug #1542693: remove semi-colon at end of PyImport_ImportModuleEx
5774 macro so it can be used as an expression.

Georg Brandl3ee81df2008-05-17 18:14:43 +00005780- Patch #1706: Drop support for Win9x, WinME and NT4. Python now
5781 requires Windows 2000 or greater. The _WINVER and NTDDI_VERSION
5782 macros are set to Win2k for x86/32bit builds and WinXP for AMD64
5783 builds.

Georg Brandl3ee81df2008-05-17 18:14:43 +00005798- Removed the macfs module. It had been deprecated since Python 2.5.
5799 This lead to the deprecation of macostools.touched() as it relied
5800 solely on macfs and was a no-op under OS X.
