Antoine Pitroufc69af12010-04-24 20:04:58 +000028- Issue #5103: SSL handshake would ignore the socket timeout and block
29 indefinitely if the other end didn't respond.
30
Antoine Pitrou4d3e3722010-04-24 19:57:01 +000031- The do_handshake() method of SSL objects now adjusts the blocking mode of

44 and keywords.
45
Antoine Pitroua5c4b552010-04-22 23:33:02 +000046- Issue #8108: Fix the unwrap() method of SSL objects when the socket has
47 a non-infinite timeout. Also make that method friendlier with applications
48 wanting to continue using the socket in clear-text mode, by disabling
49 OpenSSL's internal readahead. Thanks to Darryl Miles for guidance.
50
Antoine Pitrouc715a9e2010-04-21 19:28:03 +000051- Issue #8484: Load all ciphers and digest algorithms when initializing

78 designed to follow. This improves compatibility with patch tools.
79
R. David Murray27ef9372010-04-12 14:26:06 +000080- Issue #7472: Fixed typo in email.encoders module; messages using ISO-2022

111Core and Builtins
112-----------------
113
Philip Jenveyaebbaeb2010-04-06 23:24:45 +0000114- Issue #7301: Add environment variable $PYTHONWARNINGS.
115
Benjamin Peterson3a1dfa22010-04-06 21:50:00 +0000116- Issue #8329: Don't return the same lists from select.select when no fds are
117 changed.
118
Mark Dickinson82791672010-04-06 16:47:55 +0000119- Issue #8259: 1L << (2**31) no longer produces an 'outrageous shift error'
120 on 64-bit machines. The shift count for either left or right shift is
121 permitted to be up to sys.maxsize.
122
Benjamin Peterson4ceeeb02010-04-03 22:48:51 +0000123- Ensure that tokenization of identifiers is not affected by locale.

130 is called with a non-empty format string. This is an effort to
131 future-proof user code. If a derived class does not currently
132 implement __format__ but later adds its own __format__, it would
133 most likely break user code that had supplied a format string. This
134 will be changed to a DeprecationWaring in Python 3.3 and it will be
135 an error in Python 3.4.
136
Antoine Pitroua57df2c2010-03-31 21:32:15 +0000137- Issue #8268: Old-style classes (not just instances) now support weak

Georg Brandlba83f822010-03-14 09:50:54 +0000151 (SIGINT). If an error occurs while importing the site module, the error is
152 printed and Python exits. Initialize the GIL before importing the site
Victor Stinner66644262010-03-10 22:30:19 +0000153 module.
154
Collin Winter001a3952010-03-18 21:54:01 +0000155- Code objects now support weak references.

161
Antoine Pitrouf9de5342010-04-05 21:35:07 +0000162- Issue #8321: Give access to OpenSSL version numbers from the `ssl` module,
163 using the new attributes `ssl.OPENSSL_VERSION`, `ssl.OPENSSL_VERSION_INFO`
164 and `ssl.OPENSSL_VERSION_NUMBER`.
165
Benjamin Peterson76a23c12010-04-04 23:23:22 +0000166- Issue #8310: Allow dis to examine new style classes.
167
Mark Dickinson8a950712010-04-03 15:47:46 +0000168- Issue #8257: The Decimal construct now accepts a float instance
169 directly, converting that float to a Decimal of equal value:

175
Raymond Hettingera551f312010-04-04 18:34:45 +0000176- the functools module now has a total_ordering() class decorator
Georg Brandl4fabac52010-04-14 08:53:38 +0000177 to simplify the specification of rich comparisons.
Raymond Hettingera551f312010-04-04 18:34:45 +0000178
Raymond Hettingerbb006cf2010-04-04 21:45:01 +0000179- The functools module also adds cmp_to_key() as a tool to transition

Mark Dickinson7c63eee2010-04-02 22:27:36 +0000182- Issue #8294: The Fraction constructor now accepts Decimal and float
183 instances directly.
184
Mark Dickinsone096e822010-04-02 10:17:07 +0000185- Issue #7279: Comparisons involving a Decimal signaling NaN now
186 signal InvalidOperation instead of returning False. (Comparisons
Mark Dickinsonf3eeca12010-04-02 10:35:12 +0000187 involving a quiet NaN are unchanged.) Also, Decimal quiet NaNs
188 are now hashable; Decimal signaling NaNs remain unhashable.
Mark Dickinsone096e822010-04-02 10:17:07 +0000189

196 argument `-` which tells it to read files to compile from stdin. Each line
197 is read on demand and the named file is compiled immediately. (Original
198 patch by Piotr Ożarowski).
199
200- Issue #3135: Add inspect.getcallargs, which binds arguments to a function
201 like a normal call.
Benjamin Peterson7e213252010-03-30 17:58:13 +0000202
Florent Xicluna58b65662010-03-30 16:29:03 +0000203- Backwards incompatible change: Unicode codepoints line tabulation (0x0B) and
204 form feed (0x0C) are now considered linebreaks, as specified in Unicode
205 Standard Annex #14. See issue #7643.
Florent Xicluna22b24382010-03-30 08:24:06 +0000206 http://www.unicode.org/reports/tr14/

209 a Fractions instance now raise TypeError instead of returning
210 True/False. This makes Fraction <=> complex comparisons consistent with
211 int <=> complex, float <=> complex, and complex <=> complex comparisons.
212

225
Florent Xicluna9e7a4c92010-03-22 16:07:38 +0000226- Issue #7703: ctypes supports both buffer() and memoryview(). The former is

Mark Dickinson4846a8e2010-04-03 14:05:10 +0000308- Issue #8300: When passing a non-integer argument to struct.pack with any
309 integer format code, struct.pack first attempts to convert the non-integer
310 using its __index__ method. If that method is non-existent or raises
311 TypeError it goes on to try the __int__ method, as described below.

Georg Brandlba83f822010-03-14 09:50:54 +0000313- Issue #1530559: When passing a non-integer argument to struct.pack with *any*
314 integer format code (one of 'bBhHiIlLqQ'), struct.pack attempts to use the
315 argument's __int__ method to convert to an integer before packing. It also
316 produces a DeprecationWarning in this case. (In Python 2.6, the behaviour
317 was inconsistent: __int__ was used for some integer codes but not for others,
318 and the set of integer codes for which it was used differed between native
319 packing and standard packing.)

715Core and Builtins
716-----------------
717
Georg Brandlba83f822010-03-14 09:50:54 +0000718- The ``__complex__()`` method is now looked up on the class of instances to
719 make it consistent with other special methods.

Antoine Pitrou5b7139a2010-01-02 21:12:58 +0000721- Issue #7462: Implement the stringlib fast search algorithm for the `rfind`,
722 `rindex`, `rsplit` and `rpartition` methods. Patch by Florent Xicluna.
723
Mark Dickinson1b34d252010-01-01 17:27:30 +0000724- Issue #5080: A number of functions and methods previously produced a
Georg Brandlba83f822010-03-14 09:50:54 +0000725 DeprecationWarning when passed a float argument where an integer was expected.
726 These functions and methods now raise TypeError instead. The majority of the
727 effects of this change are in the extension modules, but some core functions
728 and methods are affected: notably the 'chr', 'range' and 'xrange' builtins,
729 and many unicode/str methods.

741
Georg Brandlba83f822010-03-14 09:50:54 +0000742- Issue #1811: Improve accuracy and cross-platform consistency for true division
743 of integers: the result of a/b is now correctly rounded for ints a and b (at
744 least on IEEE 754 platforms), and in particular does not depend on the
745 internal representation of a long.

753
Georg Brandlba83f822010-03-14 09:50:54 +0000754 These executables now work properly with the arch(1) command: ``arch -ppc
755 python`` will start a universal binary version of python in PPC mode (unlike
756 previous releases).

896 to 'g' for large values.
Amaury Forgeot d'Arcd7288712009-12-01 21:51:04 +0000897
Georg Brandlba83f822010-03-14 09:50:54 +0000898- Remove switch from "%f" formatting to "%g" formatting for floats larger than
899 1e50 in absolute value.
Mark Dickinson9dd5e162009-11-23 20:54:09 +0000900
Georg Brandlba83f822010-03-14 09:50:54 +0000901- Remove restrictions on precision when formatting floats. E.g., "%.120g" %

910 10.6.
Ronald Oussoren315cd0c2009-11-19 16:25:21 +0000911
Georg Brandlba83f822010-03-14 09:50:54 +0000912- Issue #7117: ``repr(x)`` for a float x returns a result based on the shortest
913 decimal string that's guaranteed to round back to x under correct rounding
914 (with round-half-to-even rounding mode). Previously it gave a string based on
915 rounding x to 17 decimal digits. repr(x) for a complex number behaves
916 similarly. On platforms where the correctly-rounded strtod and dtoa code is
917 not supported (see below), repr is unchanged.
Mark Dickinsonb678de82009-11-19 18:41:49 +0000918
Georg Brandlba83f822010-03-14 09:50:54 +0000919- Issue #7117: On almost all platforms: float-to-string and string-to-float
920 conversions within Python are now correctly rounded. Places these conversions
921 occur include: str for floats and complex numbers; the float and complex
922 constructors; old-style and new-style numeric formatting; serialization and
923 deserialization of floats and complex numbers using marshal, pickle and json;
924 parsing of float and imaginary literals in Python code; Decimal-to-float
925 conversion.
Mark Dickinsonb678de82009-11-19 18:41:49 +0000926
Georg Brandlba83f822010-03-14 09:50:54 +0000927 The conversions use a Python-adapted version of David Gay's well-known dtoa.c,
928 providing correctly-rounded strtod and dtoa C functions. This code is
929 supported on Windows, and on Unix-like platforms using gcc, icc or suncc as
930 the C compiler. There may be a small number of platforms on which correct
931 operation of this code cannot be guaranteed, so the code is not used: notably,
932 this applies to platforms where the C double format is not IEEE 754 binary64,
933 and to platforms on x86 hardware where the x87 FPU is set to 64-bit precision
934 and Python's configure script is unable to determine how to change the FPU
935 precision. On these platforms conversions use the platform strtod and dtoa,
936 as before.

Georg Brandlba83f822010-03-14 09:50:54 +0000938- Issue #7117: Backport round implementation from Python 3.x. ``round()`` now
939 uses the correctly-rounded string <-> float conversions described above (when
940 available), and so produces correctly rounded results that will display nicely
941 under the float repr. There are two related small changes: (1) round now
942 accepts any class with an ``__index__()`` method for its second argument (but
943 no longer accepts floats for the second argument), and (2) an excessively
944 large second integer argument (e.g., ``round(1.234, 10**100)``) no longer
945 raises an exception.

Georg Brandlba83f822010-03-14 09:50:54 +00001088 (1) inf and nan strings with trailing whitespace were incorrectly rejected;
1089 (2) parsing of strings representing infinities and nans was locale aware; and
1090 (3) the interpretation of fromhex('-nan') didn't match that of float('-nan').

Georg Brandlba83f822010-03-14 09:50:54 +00001092- Issue #5920: For ``float.__format__()``, change the behavior with the empty
1093 presentation type (that is, not one of 'e', 'f', 'g', or 'n') to be like 'g'
1094 but with at least one decimal point and with a default precision
1095 of 12. Previously, the behavior the same but with a default precision of 6.
1096 This more closely matches ``str()``, and reduces surprises when adding
1097 alignment flags to the empty presentation type. This also affects the new
1098 complex.__format__ in the same way.
1099
1100- Issue #5890: In subclasses of 'property' the __doc__ attribute was shadowed by

Skip Montanarof205c132008-12-23 03:30:15 +00001264- Added test case to ensure attempts to read from a file opened for writing

Georg Brandlba83f822010-03-14 09:50:54 +00001281- Issue #4445: Replace ``sizeof(PyStringObject)`` with
1282 ``offsetof(PyStringObject, ob_sval) + 1`` when allocating memory for str
1283 instances. On a typical machine this saves 3 bytes of memory (on average) per

1295
Georg Brandlba83f822010-03-14 09:50:54 +00001296- Issue #4233: Changed semantic of ``_fileio.FileIO``'s ``close()`` method on
1297 file objects with closefd=False. The file descriptor is still kept open but
1298 the file object behaves like a closed file. The ``FileIO`` object also got a
1299 new readonly attribute ``closefd``.

Benjamin Peterson399b1fe2008-10-25 02:53:28 +00001319- Using ``nonlocal`` as a variable name will now raise a Py3k SyntaxWarning

Georg Brandlba83f822010-03-14 09:50:54 +00001322- On windows, ``os.chdir()`` given unicode was not working if
1323 GetCurrentDirectoryW returned a path longer than MAX_PATH. (But It's doubtful
1324 this code path is really executed because I cannot move to such directory on
1325 win2k)

Georg Brandlba83f822010-03-14 09:50:54 +00001327- Issue #4069: When ``set.remove(element)`` is used with a set element, the
1328 element is temporarily replaced with an equivalent frozenset. But the
1329 eventual KeyError would always report the empty ``frozenset()`` as the missing
1330 key. Now it correctly refers to the initial element.

Walter Dörwalded960ac2009-05-03 22:36:33 +00001350- Issue #5108: Handle %s like %S and %R in PyUnicode_FromFormatV(): Call
1351 PyUnicode_DecodeUTF8() once, remember the result and output it in a second
1352 step. This avoids problems with counting UTF-8 bytes that ignores the effect
1353 of using the replace error handler in PyUnicode_DecodeUTF8().
1354
Walter Dörwald726ba8e2009-05-06 14:32:35 +00001355- Issue #3739: The unicode-internal encoder now reports the number of characters

1357
Georg Brandlba83f822010-03-14 09:50:54 +00001358- Issue #2422: When compiled with the ``--with-valgrind`` option, the pymalloc

1360 gives improved memory leak detection when running under Valgrind, while taking
1361 advantage of pymalloc at other times.

2528 __long__ method could be packed by 'q', 'Q', '*q', '*Q'; for x with
2529 neither __int__ nor __long__, TypeError used to be raised (with a

Martin v. Löwis9fa5a282008-09-11 06:53:30 +00002726- Issue #3642: Suppress warning in obmalloc when size_t is larger than uint.
2727
Amaury Forgeot d'Arc05e34492008-09-10 22:04:45 +00002728- Issue #3743: In a few places, PY_FORMAT_SIZE_T was incorrectly used with
2729 PyString_FromFormat or PyErr_Format to display size_t values. The macro
2730 PY_FORMAT_SIZE_T is designed to select the correct format for the OS
2731 ``printf`` function, whereas PyString_FromFormat has an independent
2732 implementation and uses "%zd" on all platforms for size_t values.
2733 This makes a difference on win64, where ``printf`` needs "%Id" to display
2734 64bit values.

Benjamin Peterson97179b02008-09-09 20:55:01 +00002736- Issue #3634: _weakref.ref(Exception).__init__() gave invalid return value on

2740 object; previously an int would be returned for small values. the __long__
2741 method is allowed to return either an int or a long, but the behaviour of
2742 float objects should not change to respect backward compatibility.
2743
Amaury Forgeot d'Arc3571fbf2008-09-01 19:52:00 +00002744- Issue #3751: str.rpartition would perform a left-partition when called with

Vinay Sajip35e3b032008-09-01 14:33:59 +00002750 PyArg_ParseTuple and friends, which occurred when the argument for "s*"
Antoine Pitroud4ae97b2008-08-29 18:39:48 +00002751 was correctly parsed but parsing of subsequent arguments failed.
2752
Vinay Sajip35e3b032008-09-01 14:33:59 +00002753- Issue #2534: speed up isinstance() and issubclass() by 50-70%, so as to
Antoine Pitrou0668c622008-08-26 22:42:08 +00002754 match Python 2.5 speed despite the __instancecheck__ / __subclasscheck__
2755 mechanism. In the process, fix a bug where isinstance() and issubclass(),
2756 when given a tuple of classes as second argument, were looking up
2757 __instancecheck__ / __subclasscheck__ on the tuple rather than on each
2758 type object.
2759
Neal Norwitz18aa3882008-08-24 05:04:52 +00002760- Fix crashes on memory allocation failure found with failmalloc.

2903-----------------
2904
Guido van Rossumf8402962008-08-20 15:01:50 +00002905- Issue #1878: Remove Py_TPFLAGS_HAVE_VERSION_TAG from
2906 Py_TPFLAGS_DEFAULT when not building the core. This means 3rd party
2907 extensions do not automatically benefit from the class attribute
2908 cache; they will have to explicitly add Py_TPFLAGS_HAVE_VERSION_TAG
2909 to their tp_flags field if they care. This is a backwards
2910 compatibility feature; in 3.0, all types will use the cache by
2911 default.
2912
Benjamin Petersonf647dc12008-08-20 01:27:30 +00002913- Keyword arguments can now follow starred arguments. (``f(a, *args,

2917 value again.

2928
Amaury Forgeot d'Arc39fd6722008-07-31 21:28:03 +00002929- Issue #3479: On platforms where sizeof(int) is smaller than sizeof(long)
2930 (64bit Unix, for example), unichr() would truncate its argument and return
2931 u'\x00' for unichr(2**32). Now it properly raises an OverflowError.
2932
Neal Norwitze7d8be82008-07-31 17:17:14 +00002933- Apply security patches from Apple.
2934
Amaury Forgeot d'Arc246daed2008-07-31 00:42:16 +00002935- Issue #2542: Now that issubclass() may call arbitrary code, ensure that
2936 PyErr_ExceptionMatches returns 0 when an exception occurs there.
2937
Antoine Pitrou92f82162008-07-25 22:22:08 +00002938- Issue #1819: function calls with several named parameters are now on
2939 average 35% faster (as measured by pybench).
2940
Amaury Forgeot d'Arce4921fe2008-07-21 22:00:38 +00002941- Issue #2378: An unexpected UnboundLocalError or NameError could appear when
2942 the python debugger steps into a class statement: the free variables (local
2943 variables defined in an outer scope) would be deleted from the outer scope.
2944
Gregory P. Smith0470bab2008-07-22 04:46:32 +00002945- Issue #2620: Overflow checking when allocating or reallocating memory
2946 was not always being done properly in some python types and extension
2947 modules. PyMem_MALLOC, PyMem_REALLOC, PyMem_NEW and PyMem_RESIZE have
2948 all been updated to perform better checks and places in the code that
2949 would previously leak memory on the error path when such an allocation
2950 failed have been fixed.

2956
Benjamin Petersone977ad42008-08-20 01:42:01 +00002957- The methods ``is_in_tuple()``, ``is_vararg()``, and ``is_keywordarg()`` of
2958 symtable.Symbol have been deprecated for removal in 3.0 and the next release.
2959
Amaury Forgeot d'Arc351ffb82008-08-18 19:23:47 +00002960- Issue #2234: distutils failed for some versions of the cygwin compiler. The
2961 version reported by these tools does not necessarily follow the python
2962 version numbering scheme, so the module is less strict when parsing it.
2963
Nick Coghlanf70385a2008-08-18 12:42:46 +00002964- Issue #2235: Added Py3k warnings for types which will become unhashable
2965 under the stricter __hash__ inheritance rules in 3.0. Several types
2966 which did not meet the rules for hash invariants and were already
2967 unhashable in 3.0 have now been explicitly flagged as unhashable in
2968 2.6 as well (collections.Mapping, collections.Set, unittest.TestSuite,
2969 xml.dom.minidom.NamedNodeMap, numbers.Number, UserList.UserList)
2970
Brett Cannon88f801d2008-08-18 00:46:22 +00002971- Update __all__ for cookielib, csv, os, urllib2, and weakref to include things
2972 imported into the module but exposed as part of the module's API.
2973

2994
Antoine Pitroub90a8be2008-08-15 21:03:21 +00002995- Issue #2676: in the email package, content-type parsing was hanging on
2996 pathological input because of quadratic or exponential behaviour of a
2997 regular expression.

Brett Cannonbf3157b2008-08-14 05:00:03 +00003002- Silence the DeprecationWarning of rfc822 when it is imported by mimetools
3003 since mimetools itself is deprecated. Because modules are cached, all
3004 subsequent imports of rfc822 will not raise a visible DeprecationWarning.
3005
Antoine Pitrou9fcd4b32008-08-11 17:21:36 +00003006- Issue #3134: shutil referenced undefined WindowsError symbol.

3018 to _sre.compile() will now be rejected. This should not affect anybody
3019 since the re.compile() function never generates invalid re-bytecode.

Skip Montanaroa032bf42008-08-08 22:52:51 +00003021- Issue #3436: Make csv.DictReader's fieldnames attribute a property so that
3022 upon first access it can be automatically initialized from the csv file if
3023 it wasn't initialized during instantiation.
3024
Brett Cannon3aa2a492008-08-06 22:28:09 +00003025- Issue #2338: Create imp.reload() to help with transitioning to Python 3.0 as
3026 the reload() built-in has been removed.
3027
Brett Cannon7e30b672008-08-04 21:52:25 +00003028- Changed code in the following modules/packages to remove warnings raised

Benjamin Peterson01a24322008-07-28 23:35:27 +00003039- Issue #2523: Fix quadratic behaviour when read()ing a binary file without
Antoine Pitroude781a42008-08-09 12:43:23 +00003040 asking for a specific length. This problem only affected files opened
3041 using the new "io" module, not the built-in open() function.

3065
Antoine Pitrou5fdfa3e2008-07-25 19:42:26 +00003066- Issue #3394: zipfile.writestr sets external attributes when passed a
3067 file name rather than a ZipInfo instance, so files are extracted with
3068 mode 0600 rather than 000 under Unix.
3069
Gregory P. Smitha36f8fe2008-08-04 00:13:29 +00003070- Issue #1857: subprocess.Popen.poll gained an additional _deadstate keyword
3071 argument in python 2.5, this broke code that subclassed Popen to include its

Nick Coghlan6e8fef02008-08-18 13:14:22 +00003082- Issue #2235: the C API function PyObject_HashNotImplemented and its
3083 interaction with the tp_hash slot (added in 2.6b2) are now documented
3084
Nick Coghlan2a0c2b12008-08-04 12:47:17 +00003085- Issue #643841: The language reference now provides more detailed
3086 coverage of the lookup process for special methods. The disclaimers
3087 regarding lack of coverage of new-style classes have also been
3088 removed, since the coverage is now fairly reasonable.

3092================================
3093
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00003094*Release date: 17-Jul-2008*
3095
Raymond Hettingere3ae6552008-06-20 04:18:15 +00003096Core and Builtins
3097-----------------
3098
Georg Brandl3e483f62008-07-16 22:57:41 +00003099- Issue #3156: Fix inconsistent behavior of the bytearray type: all
3100 its methods now allow for items objects that can be converted to
3101 an integer using operator.index().
3102
Mark Dickinson64b7e502008-07-16 09:40:03 +00003103- Issue #3360: Fix incorrect parsing of '020000000000.0', which
3104 produced a ValueError instead of giving the correct float.
3105
Eric Smitha5fa5a22008-07-16 00:11:49 +00003106- Issue #3083: Add alternate (#) formatting for bin, oct, hex output
3107 for str.format(). This adds the prefix 0b, 0o, or 0x, respectively.
3108
Mark Dickinson7103aa42008-07-15 19:08:33 +00003109- Issue #3008: the float type has a new instance method 'float.hex'
3110 and a new class method 'float.fromhex' to convert floating-point
3111 numbers to and from hexadecimal strings, respectively.
3112
Nick Coghlan6d6bd442008-07-15 15:40:22 +00003113- Issue #2235: __hash__ is once again inherited by default. To allow
3114 collections.Hashable to remain meaningful in the presence of the
3115 default hash implementation (object.__hash__), it is now possible
3116 to explicit block inheritance of hash by setting __hash__=None at
3117 the Python level, or tp_hash=PyObject_HashNotImplemented at the C
3118 level.
3119
Nick Coghlanb028f502008-07-13 14:52:36 +00003120- Issue #3221: Issue a RuntimeWarning instead of raising SystemError if
3121 the parent module cannot be found while performing an absolute import.
3122 This means that an incorrectly defined __package__ attribute will
3123 now only prevent relative imports in that module rather than causing
3124 all imports from that module to fail.
3125
Nick Coghlan14ff9942008-07-08 14:21:42 +00003126- Issue #2517: Allow unicode messages in Exceptions again by correctly
3127 bypassing the instance dictionary when looking up __unicode__ on
3128 new-style classes.
3129
Amaury Forgeot d'Arcbdd941f2008-07-01 20:38:04 +00003130- Issue #3242: Fix a crash inside the print statement, if sys.stdout is
3131 set to a custom object whose write() method happens to install
3132 another file in sys.stdout.
3133
Amaury Forgeot d'Arc1f40c8a2008-06-30 22:42:40 +00003134- Issue #3088: Corrected a race condition in classes derived from
3135 threading.local: the first member set by a thread could be saved in
3136 another thread's dictionary.
3137
Mark Dickinson1ec2fcd2008-06-20 14:53:43 +00003138- Issue #3004: Minor change to slice.indices(): the start and stop
3139 arguments are now treated identically, making the behaviour easier
3140 to describe and understand. For example, slice(None, -10,
3141 1).indices(9) now returns (0, 0, 1) instead of (0, -1, 1), and
3142 slice(None, 10, -1).indices(10) returns (9, 9, -1) instead of (9,
3143 10, -1).
3144
Georg Brandl278fc502008-07-19 12:46:12 +00003145- Issue #3219: Calling a function with repeated keyword arguments,
3146 f(a=2, a=23), would not cause a syntax error. This was a regression
3147 from 2.4 caused by the switch to the new compiler.
Benjamin Peterson175e4d92008-07-01 19:34:52 +00003148
Georg Brandl278fc502008-07-19 12:46:12 +00003149- Issue #2862: Make int and float freelist management consistent with
3150 other freelists. Changes their CompactFreeList apis into
3151 ClearFreeList apis and calls them via gc.collect().
Gregory P. Smith2fe77062008-07-06 03:35:58 +00003152

3154-------
3155
Thomas Heller57adf222008-08-14 19:10:48 +00003156- Issue #3554: ctypes.string_at and ctypes.wstring_at did call Python
3157 api functions without holding the GIL, which could lead to a fatal
3158 error when they failed.
3159
Martin v. Löwisaabf4042008-08-02 07:20:25 +00003160- Issue #799428: Fix Tkinter.Misc._nametowidget to unwrap Tcl command objects.

3169 ForkingPickler.register() to resolve conflict with ctypes.
3170
Vinay Sajip51e65192008-07-18 09:01:10 +00003171- Issue #3090: Fixed ARCHFLAGS parsing on OS/X

Thomas Heller880f5292008-07-15 19:39:38 +00003173- Issue #3313: Fixed a crash when a failed dlopen() call does not set
3174 a valid dlerror() message.
3175
Thomas Heller2bad6572008-07-15 17:19:50 +00003176- Issue #3258: Fixed a crash when a ctypes POINTER type to an
3177 incomplete structure was created.
3178
Brett Cannon3d0b9f02008-07-13 01:15:07 +00003179- Issue #3339: dummy_thread.acquire() should not return None.

Raymond Hettingerb01713e2008-07-10 14:34:57 +00003181- Issue #3285: Fractions from_float() and from_decimal() accept Integral arguments.
3182
Andrew M. Kuchlingcc3f2b12008-07-10 14:43:31 +00003183- Issue #3301: Bisect module behaved badly when lo was negative.
Raymond Hettinger3cd1e422008-07-10 14:03:19 +00003184
Amaury Forgeot d'Arc0f7cddc2008-07-06 21:34:39 +00003185- Issue #839496: SimpleHTTPServer used to open text files in text mode. This is
3186 both unnecessary (HTTP allows text content to be sent in several forms) and
Andrew M. Kuchlingcc3f2b12008-07-10 14:43:31 +00003187 wrong because the actual transmitted size could differ from the
Amaury Forgeot d'Arc0f7cddc2008-07-06 21:34:39 +00003188 content-length. The problem had been corrected in the 2.4 branch, but never
3189 merged into trunk.
3190
Georg Brandle78fbcc2008-07-05 10:13:36 +00003191- Issue #2663: add filtering capability to shutil.copytree().

3197- Issue #1746: Correct handling of zipfile archive comments (previously
3198 archives with comments over 4k were flagged as invalid). Allow writing
Vinay Sajip51e65192008-07-18 09:01:10 +00003199 Zip files with archives by setting the 'comment' attribute of a ZipFile.

Vinay Sajip51e65192008-07-18 09:01:10 +00003201- Issue #449227: The rlcompleter module now adds "(" to callable objects
Andrew M. Kuchlingcc3f2b12008-07-10 14:43:31 +00003202 when completed.
Facundo Batista66c52772008-07-02 16:52:55 +00003203
Nick Coghlanc060b0e2008-07-02 13:09:19 +00003204- Issue #3190: Pydoc now hides the automatic module attribute __package__ (the
3205 handling is now the same as that of other special attributes like __name__).
3206
Brett Cannon8bb8fa52008-07-02 01:57:08 +00003207- Issue #2885 (partial): The urllib.urlopen() function has been deprecated for
3208 removal in Python 3.0 in favor of urllib2.urlopen().

Georg Brandl5cc774e2008-06-11 20:28:06 +00003597 PPC64 and x86_64 support in one binary).
Ronald Oussoren5640ce22008-06-05 12:58:24 +00003598
3599 This is controlled by the configure argument ``--with-universal-archs``:
3600
3601 - ``--with-universal-archs=all``: install 4-way universal
3602
3603 - ``--with-universal-archs=32-bit``: install 2-way universal, 32-bit (the default)
3604
3605 - ``--with-universal-archs=64-bit``: install 2-way universal, 64-bit
3606
3607 This option should be used in combination with ``--enable-universalsdk=``.
3608
3609 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 +00003659- Issue #1631171: Re-implement the 'warnings' module in C (the
3660 original Python code has been kept as backup). This will allow for
3661 using the 'warning's machinery in such places as the parser where
3662 use of pure Python code is not possible. Both the ``showarning()``
3663 and ``formatwarning()`` gain an optional 'line' argument which is
3664 not called by default for backwards-compatibility reasons. Setting
3665 ``warnings.showwarning()`` to an implementation that lacks support
3666 for the ``line`` argument will raise a DeprecationWarning.

Georg Brandl3ee81df2008-05-17 18:14:43 +00003729- Issue #2550: The approach used by client/server code for obtaining
3730 ports to listen on in network-oriented tests has been refined in an
3731 effort to facilitate running multiple instances of the entire
3732 regression test suite in parallel without issue.
3733 test_support.bind_port() has been fixed such that it will always
3734 return a unique port -- which wasn't always the case with the
3735 previous implementation, especially if socket options had been set
3736 that affected address reuse (i.e. SO_REUSEADDR, SO_REUSEPORT). The
3737 new implementation of bind_port() will actually raise an exception
3738 if it is passed an AF_INET/SOCK_STREAM socket with either the
3739 SO_REUSEADDR or SO_REUSEPORT socket option set. Furthermore, if
3740 available, bind_port() will set the SO_EXCLUSIVEADDRUSE option on
3741 the socket it's been passed. This currently only applies to
3742 Windows. This option prevents any other sockets from binding to the
3743 host/port we've bound to, thus removing the possibility of the
3744 'non-deterministic' behaviour, as Microsoft puts it, that occurs
3745 when a second SOCK_STREAM socket binds and accepts to a host/port
3746 that's already been bound by another socket. The optional preferred
3747 port parameter to bind_port() has been removed. Under no
3748 circumstances should tests be hard coding ports!
3749
3750 test_support.find_unused_port() has also been introduced, which will
3751 pass a temporary socket object to bind_port() in order to obtain an
3752 unused port. The temporary socket object is then closed and
3753 deleted, and the port is returned. This method should only be used
3754 for obtaining an unused port in order to pass to an external program
3755 (i.e. the -accept [port] argument to openssl's s_server mode) or as
3756 a parameter to a server-oriented class that doesn't give you direct
3757 access to the underlying socket used.
3758
3759 Finally, test_support.HOST has been introduced, which should be used
3760 for the host argument of any relevant socket calls (i.e. bind and
3761 connect).
Trent Nelsone41b0062008-04-08 23:47:30 +00003762
3763 The following tests were updated to following the new conventions:
Georg Brandl3ee81df2008-05-17 18:14:43 +00003764 test_socket, test_smtplib, test_asyncore, test_ssl, test_httplib,

3766 test_asynchat and test_socket_ssl.
3767
Georg Brandl3ee81df2008-05-17 18:14:43 +00003768 It is now possible for multiple instances of the regression test
3769 suite to run in parallel without issue.

4035Core and builtins
4036-----------------
4037
Fred Drakea8ee94b2008-03-01 02:45:07 +00004038- Issue #2051: pyc and pyo files are no longer created with permission
Barry Warsaw52973612008-03-01 02:23:38 +00004039 644. The mode is now inherited from the py file.
Christian Heimes40346852008-02-23 17:52:07 +00004040
Georg Brandlad61bc82008-02-23 15:11:18 +00004041- Issue #2067: file.__exit__() now calls subclasses' close() method.
4042
4043- Patch #1759: Backport of PEP 3129 class decorators.
Christian Heimes5224d282008-02-23 15:01:05 +00004044
Vinay Sajipb7edfc42008-04-02 21:10:23 +00004045- Issue #1881: An internal parser limit has been increased. Also see
Facundo Batistafc2d0102008-02-23 12:01:13 +00004046 issue 215555 for a discussion.
4047
Eric Smitha73fbe72008-02-23 03:09:44 +00004048- Added the future_builtins module, which contains hex() and oct().
4049 These are the PEP 3127 version of these functions, designed to be
4050 compatible with the hex() and oct() builtins from Python 3.0. They
4051 differ slightly in their output formats from the existing, unchanged
4052 Python 2.6 builtins. The expected usage of the future_builtins
4053 module is:
4054 from future_builtins import hex, oct
4055
Eric Smith7ef40bf2008-02-20 23:34:22 +00004056- Issue #1600: Modifed PyOS_ascii_formatd to use at most 2 digit
4057 exponents for exponents with absolute value < 100. Follows C99
4058 standard. This is a change on Windows, which would use 3 digits.
4059 Also, added 'n' to the formats that PyOS_ascii_formatd understands,
4060 so that any alterations it does to the resulting string will be
4061 available in stringlib/formatter.h (for float.__format__).
4062
Eric Smith5a3c1352008-02-19 13:21:56 +00004063- Implemented PEP 3101, Advanced String Formatting. This adds a new
4064 builtin format(); a format() method for str and unicode; a
4065 __format__() method to object, str, unicode, int, long, float, and
4066 datetime; the class string.Formatter; and the C API
4067 PyObject_Format().
4068
Georg Brandl3ee81df2008-05-17 18:14:43 +00004069- Fixed several potential crashes, all caused by specially crafted
4070 __del__ methods exploiting objects in temporarily inconsistent
4071 state.
Amaury Forgeot d'Arc632fad32008-02-16 20:55:24 +00004072
Vinay Sajipb7edfc42008-04-02 21:10:23 +00004073- Issue #2115: Important speedup in setting __slot__ attributes. Also
Georg Brandl3ee81df2008-05-17 18:14:43 +00004074 prevent a possible crash: an Abstract Base Class would try to access
4075 a slot on a registered virtual subclass.
Amaury Forgeot d'Arc60d6c7f2008-02-15 21:22:45 +00004076
Georg Brandl3ee81df2008-05-17 18:14:43 +00004077- Fixed repr() and str() of complex numbers with infinity or nan as
4078 real or imaginary part.
Christian Heimes2f0da532008-02-15 06:57:08 +00004079
Georg Brandl3ee81df2008-05-17 18:14:43 +00004080- Clear all free lists during a gc.collect() of the highest generation
4081 in order to allow pymalloc to free more arenas. Python may give back
4082 memory to the OS earlier.
Christian Heimes3b718a72008-02-14 12:47:33 +00004083
Georg Brandl3ee81df2008-05-17 18:14:43 +00004084- Issue #2045: Fix an infinite recursion triggered when printing a
4085 subclass of collections.defaultdict, if its default_factory is set
4086 to a bound method.
Amaury Forgeot d'Arcb01aa432008-02-08 00:56:02 +00004087
Christian Heimesf75dbef2008-02-08 00:11:31 +00004088- Fixed a minor memory leak in dictobject.c. The content of the free
4089 list was not freed on interpreter shutdown.
4090
Georg Brandl21e99f42010-03-07 15:23:59 +00004091- Limit free list of method and built-in function objects to 256
Georg Brandl3ee81df2008-05-17 18:14:43 +00004092 entries each.
Christian Heimes6075a822008-02-06 12:44:34 +00004093
Georg Brandl3ee81df2008-05-17 18:14:43 +00004094- Patch #1953: Added ``sys._compact_freelists()`` and the C API
4095 functions ``PyInt_CompactFreeList`` and ``PyFloat_CompactFreeList``
Christian Heimes422051a2008-02-04 18:00:12 +00004096 to compact the internal free lists of pre-allocted ints and floats.
4097
Georg Brandl3ee81df2008-05-17 18:14:43 +00004098- Issue #1983: Fixed return type of fork(), fork1() and forkpty()
4099 calls. Python expected the return type int but the fork familie
4100 returns pi_t.
Christian Heimes951cc0f2008-01-31 23:08:23 +00004101
Georg Brandl3ee81df2008-05-17 18:14:43 +00004102- Issue #1678380: Fix a bug that identifies 0j and -0j when they
4103 appear in the same code unit.
Mark Dickinson105be772008-01-31 22:17:37 +00004104
Georg Brandl3ee81df2008-05-17 18:14:43 +00004105- Issue #2025: Add tuple.count() and tuple.index() methods to comply
4106 with the collections.Sequence API.
Raymond Hettinger5b07ebc2008-02-07 00:54:20 +00004107
Georg Brandl3ee81df2008-05-17 18:14:43 +00004108- Patch #1970 by Antoine Pitrou: Speedup unicode whitespace and
4109 linebreak detection
Christian Heimes4d4f2702008-01-30 11:32:37 +00004110
Georg Brandl3ee81df2008-05-17 18:14:43 +00004111- Added ``PyType_ClearCache()`` and ``sys._clear_type_cache`` to clear
4112 the internal lookup cache for ref leak tests.
Christian Heimes908caac2008-01-27 23:34:59 +00004113
Georg Brandl3ee81df2008-05-17 18:14:43 +00004114- Patch #1473257: generator objects gain a gi_code attribute. This is
4115 the same object as the func_code attribute of the function that
4116 produced the generator.
Georg Brandl0cdf9a32008-01-26 14:14:20 +00004117
Georg Brandl3ee81df2008-05-17 18:14:43 +00004118- Issue #1920: "while 0" statements were completely removed by the
4119 compiler, even in the presence of an "else" clause, which is
4120 supposed to be run when the condition is false. Now the compiler
4121 correctly emits bytecode for the "else" suite.
Amaury Forgeot d'Arc31eaafe2008-01-24 22:59:25 +00004122
Guido van Rossumeead05f2008-01-24 18:21:02 +00004123- A few crashers fixed: weakref_in_del.py (issue #1377858);
4124 loosing_dict_ref.py (issue #1303614, test67.py);
4125 borrowed_ref_[34].py (not in tracker).
4126
Vinay Sajipd7cf32e2008-01-24 12:43:33 +00004127- Issue #1069410: The "can't load dll" message box on Windows is
Christian Heimesb2302ba2008-01-23 17:15:06 +00004128 suppressed while an extension is loaded by calling SetErrorMode in
4129 dynload_win.c. The error is still reported properly.
4130
Georg Brandl3ee81df2008-05-17 18:14:43 +00004131- Issue #1915: Python compiles with --enable-unicode=no again. However
Christian Heimes082c9b02008-01-23 14:20:50 +00004132 several extension methods and modules do not work without unicode
4133 support.
4134
Georg Brandl26543b12008-01-21 18:36:51 +00004135- Issue #1882: when compiling code from a string, encoding cookies in the
4136 second line of code were not always recognized correctly.
4137
Georg Brandl14404b62008-01-19 19:27:05 +00004138- Issue #1679: "0x" was taken as a valid integer literal.
4139
Georg Brandl6caad7d2008-01-26 14:19:22 +00004140- Issue #1865: ``bytes`` as an alias for ``str`` and b"" as an alias "" were
Christian Heimes288e89a2008-01-18 18:24:07 +00004141 added.
4142
Christian Heimesc94e2b52008-01-14 04:13:37 +00004143- sys.float_info / PyFloat_GetInfo: The floating point information
4144 object was converted from a dict to a specialized structseq object.
4145
Georg Brandl3ee81df2008-05-17 18:14:43 +00004146- Patch #1816: Added sys.flags structseq. It exposes the status of
4147 most command line arguments and PYTHON* environment variables.
Christian Heimesf31b69f2008-01-14 03:42:48 +00004148
Georg Brandl3ee81df2008-05-17 18:14:43 +00004149- Objects/structseq.c: Implemented new structseq representation. The
4150 patch makes structseqs (e.g. the return value of os.stat) more
4151 readable.
Christian Heimes9c201962008-01-14 03:33:52 +00004152
Georg Brandl3ee81df2008-05-17 18:14:43 +00004153- Patch #1700288: added a type attribute cache that caches method
4154 accesses, resulting in speedups in heavily object-oriented code.
Amaury Forgeot d'Arce4c270c2008-01-14 00:29:41 +00004155
Neal Norwitz3fc15b82008-01-10 05:42:58 +00004156- Bug #1776: __import__() no longer accepts filenames on any platform.
4157 The first parameter to __import__() must be a valid module name.
Christian Heimes3403f152008-01-09 19:56:33 +00004158
Georg Brandlaed6c662008-01-07 17:25:53 +00004159- Patch #1668: renamed THREADDEBUG envvar to PYTHONTHREADDEBUG.
4160
Georg Brandl3ee81df2008-05-17 18:14:43 +00004161- Patch #602345: Add -B command line option, PYTHONDONTWRITEBYTECODE
4162 envvar and sys.dont_write_bytecode attribute. All these can be set
4163 to forbid Python to attempt to write compiled bytecode files.
Georg Brandl2da0fce2008-01-07 17:09:35 +00004164
Georg Brandl3ee81df2008-05-17 18:14:43 +00004165- Improve some exception messages when Windows fails to load an
4166 extension module. Now we get for example '%1 is not a valid Win32
4167 application' instead of 'error code 193'.
Amaury Forgeot d'Arce0b76952008-01-04 02:04:15 +00004168
Georg Brandl3ee81df2008-05-17 18:14:43 +00004169- Bug #1481296: Fixed long(float('nan')) != 0L.

Georg Brandl3ee81df2008-05-17 18:14:43 +00004171- Issue #1640: Added math.isinf(x), math.isnan(x) and math.copysign(x,
4172 y) functions.
Christian Heimese2ca4242008-01-03 20:23:15 +00004173
Christian Heimes0a8143f2007-12-18 23:22:54 +00004174- Issue #1635: Platform independent creation and representation of NaN
Georg Brandl3ee81df2008-05-17 18:14:43 +00004175 and INF. float("nan"), float("inf") and float("-inf") now work on
4176 every platform with IEEE 754 semantics.
Christian Heimes0a8143f2007-12-18 23:22:54 +00004177
Georg Brandl3ee81df2008-05-17 18:14:43 +00004178- Compiler now generates simpler and faster code for dictionary
4179 literals. The oparg for BUILD_MAP now indicates an estimated
4180 dictionary size. There is a new opcode, STORE_MAP, for adding
4181 entries to the dictionary.
Raymond Hettingerfd7ed402007-12-18 21:24:09 +00004182
Georg Brandl3ee81df2008-05-17 18:14:43 +00004183- Issue #1638: %zd configure test fails on Linux.

4196 __package__ attribute.
4197
Georg Brandl3ee81df2008-05-17 18:14:43 +00004198- Issue #1402: Fix a crash on exit, when another thread is still
4199 running, and if the deallocation of its frames somehow calls the
4200 PyGILState_Ensure() / PyGILState_Release() functions.
Amaury Forgeot d'Arcbe49a902007-11-30 20:37:22 +00004201

4206
Georg Brandl3ee81df2008-05-17 18:14:43 +00004207- Issue #1460: The utf-7 incremental decoder did not accept truncated
4208 input. It now correctly saves its state between chunks of data.
Amaury Forgeot d'Arcf57375a2007-11-21 01:38:26 +00004209
Georg Brandl3ee81df2008-05-17 18:14:43 +00004210- Patch #1739468: Directories and zipfiles containing a __main__.py
4211 file can now be directly executed by passing their name to the
4212 interpreter. The directory/zipfile is automatically inserted as the
4213 first entry in sys.path.
Nick Coghlan327a39b2007-11-18 11:56:28 +00004214
Georg Brandl3ee81df2008-05-17 18:14:43 +00004215- Issue #1265: Fix a problem with sys.settrace, if the tracing
4216 function uses a generator expression when at the same time the
4217 executed code is closing a paused generator.
Amaury Forgeot d'Arc0d75f092007-11-13 21:54:28 +00004218
Raymond Hettinger1760c8a2007-11-08 02:52:43 +00004219- sets and frozensets now have an isdisjoint() method.
4220
Raymond Hettinger3f8caa32007-10-24 01:28:33 +00004221- optimize the performance of builtin.sum().
4222
Neal Norwitz44f326e2007-10-05 05:29:17 +00004223- Fix warnings found by the new version of the Coverity checker.
4224
Georg Brandl21e99f42010-03-07 15:23:59 +00004225- The enumerate() built-in function is no longer bounded to sequences
Georg Brandl3ee81df2008-05-17 18:14:43 +00004226 smaller than LONG_MAX. Formerly, it raised an OverflowError. Now,
4227 automatically shifts from ints to longs.
Raymond Hettinger8f669372007-10-03 21:18:11 +00004228
Georg Brandl3ee81df2008-05-17 18:14:43 +00004229- Issue #1686386: Tuple's tp_repr did not take into account the
4230 possibility of having a self-referential tuple, which is possible
4231 from C code. Nor did object's tp_str consider that a type's tp_str
4232 could do something that could lead to an inifinite recursion.
4233 Py_ReprEnter() and Py_EnterRecursiveCall(), respectively, fixed the
4234 issues.
Brett Cannon0b14f242007-09-30 19:45:10 +00004235
Georg Brandl3ee81df2008-05-17 18:14:43 +00004236- Issue #1164: It was possible to trigger deadlock when using the
4237 'print' statement to write to a file since the GIL was not released
4238 as needed. Now PyObject_Print() does the right thing along with
4239 various tp_print implementations of the built-in types and those in
4240 the collections module.
Brett Cannon01531592007-09-17 03:28:34 +00004241
Georg Brandl3ee81df2008-05-17 18:14:43 +00004242- Issue #1147: Exceptions were directly allowing string exceptions in
4243 their throw() method even though string exceptions no longer
4244 allowed.
Brett Cannon4c20bc42007-09-11 21:02:28 +00004245

Brett Cannon1e534b52007-09-07 04:18:30 +00004249- Issue #1202533: Fix infinite recursion calls triggered by calls to
Georg Brandl3ee81df2008-05-17 18:14:43 +00004250 PyObject_Call() never calling back out to Python code to trigger
4251 recursion depth updates/checks. Required the creation of a static
4252 RuntimeError instance in case normalizing an exception put the
4253 recursion check value past its limit. Fixes crashers
4254 infinite_rec_(1|2|4|5).py.
Brett Cannon1e534b52007-09-07 04:18:30 +00004255

Neal Norwitz0ac60192007-05-27 04:08:54 +00004269- Add new attribute names for function objects. All the func_* become
Georg Brandl3ee81df2008-05-17 18:14:43 +00004270 __*__ attributes. (Some already existed, e.g., __doc__ and
4271 __name__.)
Neal Norwitz0ac60192007-05-27 04:08:54 +00004272
Neal Norwitz8b2bfbc2007-05-23 06:35:32 +00004273- Add -3 option to the interpreter to warn about features that are
4274 deprecated and will be changed/removed in Python 3.0.
4275
Georg Brandl2134e752007-05-21 20:34:16 +00004276- Patch #1686487: you can now pass any mapping after '**' in function
4277 calls.
4278
Collin Winter62903052007-05-18 23:11:24 +00004279- except clauses may now be spelled either "except E, target:" or
Georg Brandl3ee81df2008-05-17 18:14:43 +00004280 "except E as target:". This is to provide forwards compatibility
4281 with Python 3.0.
Collin Winter62903052007-05-18 23:11:24 +00004282
Brett Cannon229cee22007-05-05 01:34:02 +00004283- Deprecate BaseException.message as per PEP 352.
4284
Georg Brandl3ee81df2008-05-17 18:14:43 +00004285- Issue #1303614: don't expose object's __dict__ when the dict is
Georg Brandl21e99f42010-03-07 15:23:59 +00004286 inherited from a built-in base.
Armin Rigo9790a272007-05-02 19:23:31 +00004287
Vinay Sajip8549ce32007-05-06 17:53:37 +00004288- When __slots__ are set to a unicode string, make it work the same as
Neal Norwitzcbd9ee62007-04-14 05:25:50 +00004289 setting a plain string, ie don't expand to single letter identifiers.
4290
Raymond Hettinger13936692007-04-11 18:40:58 +00004291- Request #1191699: Slices can now be pickled.
4292
Raymond Hettinger4db5fe92007-04-12 04:10:00 +00004293- Request #1193128: str.translate() now allows a None argument for
4294 translations that only remove characters without re-mapping the
4295 remaining characters.
4296
Georg Brandl5cb76c12007-03-21 09:00:39 +00004297- Patch #1682205: a TypeError while unpacking an iterable is no longer
4298 masked by a generic one with the message "unpack non-sequence".
4299

4301
Guido van Rossum143b5642007-03-23 04:58:42 +00004302- Bug #1683368: The object.__init__() and object.__new__() methods are
4303 now stricter in rejecting excess arguments. The only time when
4304 either allows excess arguments is when it is not overridden and the
4305 other one is. For backwards compatibility, when both are
4306 overridden, it is a deprecation warning (for now; maybe a Py3k
Guido van Rossum234b1ff2007-03-23 19:39:01 +00004307 warning later). Also, type.__init__() insists on the same signature
4308 as supported by type.__new__().
Guido van Rossum143b5642007-03-23 04:58:42 +00004309
Georg Brandl3ee81df2008-05-17 18:14:43 +00004310- Patch #1675423: PyComplex_AsCComplex() now tries to convert an
4311 object to complex using its __complex__() method before falling back
4312 to the __float__() method. Therefore, the functions in the cmath
4313 module now can operate on objects that define a __complex__()
4314 method.
Georg Brandl2b869942007-03-17 16:08:45 +00004315
Georg Brandl3ee81df2008-05-17 18:14:43 +00004316- Patch #1623563: allow __class__ assignment for classes with
4317 __slots__. The old and the new class are still required to have the
4318 same slot names.
Žiga Seilnacht6f2d09c2007-03-16 11:59:38 +00004319

4324 ``object.__reduce_ex__()`` is called with an object that is faking
4325 its type.
Žiga Seilnacht20f43d32007-03-15 11:44:55 +00004326
Georg Brandl3ee81df2008-05-17 18:14:43 +00004327- Patch #1680015: Don't modify __slots__ tuple if it contains an

4331
Georg Brandl7b9c5552007-03-12 14:30:05 +00004332- Bug #1678647: write a newline after printing an exception in any
4333 case, even when converting the value to a string failed.
4334
Georg Brandl871f1bc2007-03-12 13:17:36 +00004335- The dir() function has been extended to call the __dir__() method on
Georg Brandl3ee81df2008-05-17 18:14:43 +00004336 its argument, if it exists. If not, it will work like before. This
4337 allows customizing the output of dir() in the presence of a
4338 __getattr__().
Georg Brandl871f1bc2007-03-12 13:17:36 +00004339
Collin Winter276887b2007-03-12 16:11:39 +00004340- Patch #922167: Python no longer segfaults when faced with infinitely
4341 self-recursive reload() calls (as reported by bug #742342).
4342

Georg Brandl3ee81df2008-05-17 18:14:43 +00004346- Patch #1491866: change the complex() constructor to allow
4347 parthensized forms. This means complex(repr(x)) now works instead of
4348 raising a ValueError.
Collin Wintere38051d2007-03-09 20:33:07 +00004349
Georg Brandlaa2321b2007-03-07 00:40:28 +00004350- Patch #703779: unset __file__ in __main__ after running a file. This
Georg Brandl3ee81df2008-05-17 18:14:43 +00004351 makes the filenames the warning module prints much more sensible
4352 when a PYTHONSTARTUP file is used.
Georg Brandlaa2321b2007-03-07 00:40:28 +00004353
Georg Brandl49aafc92007-03-07 00:34:46 +00004354- Variant of patch #697613: don't exit the interpreter on a SystemExit
4355 exception if the -i command line option or PYTHONINSPECT environment
Georg Brandl3ee81df2008-05-17 18:14:43 +00004356 variable is given, but break into the interactive interpreter just
4357 like on other exceptions or normal program exit.

4363 condition.
Georg Brandl098cd692007-03-06 12:17:50 +00004364
Georg Brandl0fca97a2007-03-05 22:28:08 +00004365- Patch #1674228: when assigning a slice (old-style), check for the
4366 sq_ass_slice instead of the sq_slice slot.
4367
Georg Brandl3ee81df2008-05-17 18:14:43 +00004368- When printing an unraisable error, don't print exceptions. before
4369 the name. This duplicates the behavior whening normally printing
4370 exceptions.
Neal Norwitz88516a62007-02-26 22:41:45 +00004371
Georg Brandl3ee81df2008-05-17 18:14:43 +00004372- Bug #1653736: Properly discard third argument to

Georg Brandl3ee81df2008-05-17 18:14:43 +00004378- Bug #1377858: Fix the segfaulting of the interpreter when an object
4379 created a weakref on itself during a __del__ call for new-style
4380 classes (classic classes still have the bug).

Georg Brandl3ee81df2008-05-17 18:14:43 +00004994- unittest now verifies more of its assumptions. In particular,
4995 TestCase and TestSuite subclasses (not instances) are no longer
4996 accepted in TestSuite.addTest(). This should cause no
4997 incompatibility since it never made sense with ordinary subclasses
4998 -- the failure just occurred later, with a more cumbersome
4999 exception.

Georg Brandl3ee81df2008-05-17 18:14:43 +00005280- Issue #829951: In the smtplib module, SMTP.starttls() now complies
5281 with RFC 3207 and forgets any knowledge obtained from the server not
5282 obtained from the TLS negotiation itself. Patch contributed by Bill
5283 Fenner.
Gregory P. Smith2b3ba582008-01-17 08:03:17 +00005284
Georg Brandl3ee81df2008-05-17 18:14:43 +00005285- Issue #1339: The smtplib.SMTP class has been refactored a bit such
Gregory P. Smithbde4ae42008-01-17 08:35:49 +00005286 that the SMTP.starttls() caller no longer needs to call ehlo()
5287 beforehand. SMTP.starttls() now raises an exception of the server
Georg Brandl3ee81df2008-05-17 18:14:43 +00005288 does not claim to support starttls. Adds the
5289 SMTP.ehlo_or_helo_if_needed() method. Patch contributed by Bill

5370 complex, tuple, list, dict, set, and frozenset. Formerly, it would
5371 silently miscode subclasses of those types. Now, it raises a
5372 ValueError instead.
Raymond Hettinger12e94202007-11-07 01:13:09 +00005373

Georg Brandl3ee81df2008-05-17 18:14:43 +00005388 time so that opening a database previously created with the DB_DUP
5389 or DB_DUPSORT flag set will keep the proper behavior on subsequent
5390 opens. Specifically: dictionary assignment to a DB object will
5391 replace all values for a given key when the database allows
5392 duplicate values. DB users should use DB.put(k, v) when they want
5393 to store duplicates; not DB[k] = v.
Gregory P. Smithec10a4a2007-11-05 02:32:26 +00005394

5400 characters with ASCII value less than 32. Also, it correctly quotes
5401 dots only if they occur on a single line, as opposed to the previous
5402 behavior of quoting dots if they are the second character of any
5403 line.
Georg Brandl4aef7272007-03-13 22:49:43 +00005404

Georg Brandl3ee81df2008-05-17 18:14:43 +00005728- Unified naming convention for free lists and their limits. All free
5729 lists in Object/ are named ``free_list``, the counter ``numfree``
5730 and the upper limit is a macro ``PyName_MAXFREELIST`` inside an
5731 #ifndef block.
Christian Heimes5b970ad2008-02-06 13:33:44 +00005732
Georg Brandl3ee81df2008-05-17 18:14:43 +00005733- ``PySet_Add()`` can now modify a newly created frozenset. Similarly
5734 to ``PyTuple_SetItem``, it can be used to populate a brand new
5735 frozenset; but it does not steal a reference to the added item.
Amaury Forgeot d'Arccab3d982008-02-03 22:51:43 +00005736
Vinay Sajipb7edfc42008-04-02 21:10:23 +00005737- Added ``PySet_Check()`` and ``PyFrozenSet_Check()`` to the set API.

Georg Brandl3ee81df2008-05-17 18:14:43 +00005739- Backport of PyUnicode_FromString(), _FromStringAndSize(), _Format
5740 and _FormatV from Python 3.0. Made PyLong_AsSsize_t and
5741 PyLong_FromSsize_t public functions.
Georg Brandl6caad7d2008-01-26 14:19:22 +00005742
5743- Patch #1720595: add T_BOOL to the range of structmember types.
5744
5745- Issue #1534: Added ``PyFloat_GetMax()``, ``PyFloat_GetMin()`` and
5746 ``PyFloat_GetInfo()`` to the float API.
5747
Georg Brandl3ee81df2008-05-17 18:14:43 +00005748- Issue #1521: On 64bit platforms, using PyArgs_ParseTuple with the t#
5749 of w# format code incorrectly truncated the length to an int, even
5750 when PY_SSIZE_T_CLEAN is set. The str.decode method used to return
5751 incorrect results with huge strings.
Georg Brandl6caad7d2008-01-26 14:19:22 +00005752
Georg Brandl3ee81df2008-05-17 18:14:43 +00005753- Issue #1629: Renamed Py_Size, Py_Type and Py_Refcnt to Py_SIZE,
5754 Py_TYPE and Py_REFCNT.
Georg Brandl6caad7d2008-01-26 14:19:22 +00005755
Georg Brandl3ee81df2008-05-17 18:14:43 +00005756- PEP 3123: Provide forward compatibility with Python 3.0, while
5757 keeping backwards compatibility. Add Py_Refcnt, Py_Type, Py_Size,
5758 and PyVarObject_HEAD_INIT.
Georg Brandl6caad7d2008-01-26 14:19:22 +00005759
Georg Brandl3ee81df2008-05-17 18:14:43 +00005760- Py_ssize_t fields work in structmember when HAVE_LONG_LONG is not
5761 defined.
Georg Brandl6caad7d2008-01-26 14:19:22 +00005762
5763- Patch #1733960: Allow T_LONGLONG to accept ints.
5764
5765- T_PYSSIZET can now be used in PyMemberDef lists for Py_ssize_t members.
5766
Christian Heimes000a0742008-01-03 22:16:32 +00005767- Added a new API function ``PyImport_ImportModuleNoBlock``.
5768
Georg Brandl6caad7d2008-01-26 14:19:22 +00005769- Bug #1637022: Prefix AST symbols with _Py_.
5770
5771- Fix some leftovers from the conversion from int to Py_ssize_t
5772 (relevant to strings and sequences of more than 2**31 items).
5773
5774- Make _PyGILState_NoteThreadState() static, it was not used anywhere
5775 outside of pystate.c and should not be necessary.
5776
Georg Brandl3ee81df2008-05-17 18:14:43 +00005777- ``PyImport_Import`` and ``PyImport_ImportModule`` now always do
5778 absolute imports. In earlier versions they might have used relative
5779 imports under some conditions.
Christian Heimes000a0742008-01-03 22:16:32 +00005780
Georg Brandl3ee81df2008-05-17 18:14:43 +00005781- Added case insensitive comparison methods ``PyOS_stricmp(char*,
5782 char*)`` and ``PyOS_strnicmp(char*, char*, Py_ssize_t)``.
Christian Heimes000a0742008-01-03 22:16:32 +00005783
Georg Brandl3ee81df2008-05-17 18:14:43 +00005784- Bug #1542693: remove semi-colon at end of PyImport_ImportModuleEx
5785 macro so it can be used as an expression.

5790
Georg Brandl3ee81df2008-05-17 18:14:43 +00005791- Patch #1706: Drop support for Win9x, WinME and NT4. Python now
5792 requires Windows 2000 or greater. The _WINVER and NTDDI_VERSION
5793 macros are set to Win2k for x86/32bit builds and WinXP for AMD64
5794 builds.
Christian Heimes95d64472008-02-09 19:55:22 +00005795
Georg Brandl3ee81df2008-05-17 18:14:43 +00005796- Conditionalize definition of _CRT_SECURE_NO_DEPRECATE and
5797 _CRT_NONSTDC_NO_DEPRECATE.

Brett Cannon791d56f2007-05-31 19:40:42 +00005807- buildtools now raises a DeprecationWarning.
5808
Georg Brandl3ee81df2008-05-17 18:14:43 +00005809- Removed the macfs module. It had been deprecated since Python 2.5.
5810 This lead to the deprecation of macostools.touched() as it relied
5811 solely on macfs and was a no-op under OS X.
