79
Philip Jenveyaebbaeb2010-04-06 23:24:45 +000080- Issue #7301: Add environment variable $PYTHONWARNINGS.

Benjamin Peterson3a1dfa22010-04-06 21:50:00 +000082- Issue #8329: Don't return the same lists from select.select when no fds are
83 changed.

96 is called with a non-empty format string. This is an effort to
97 future-proof user code. If a derived class does not currently
98 implement __format__ but later adds its own __format__, it would
99 most likely break user code that had supplied a format string. This
100 will be changed to a DeprecationWaring in Python 3.3 and it will be
101 an error in Python 3.4.
102
Antoine Pitroua57df2c2010-03-31 21:32:15 +0000103- Issue #8268: Old-style classes (not just instances) now support weak

Georg Brandlba83f822010-03-14 09:50:54 +0000117 (SIGINT). If an error occurs while importing the site module, the error is
118 printed and Python exits. Initialize the GIL before importing the site
Victor Stinner66644262010-03-10 22:30:19 +0000119 module.

Antoine Pitrouf9de5342010-04-05 21:35:07 +0000128- Issue #8321: Give access to OpenSSL version numbers from the `ssl` module,
129 using the new attributes `ssl.OPENSSL_VERSION`, `ssl.OPENSSL_VERSION_INFO`
130 and `ssl.OPENSSL_VERSION_NUMBER`.
131
Benjamin Peterson76a23c12010-04-04 23:23:22 +0000132- Issue #8310: Allow dis to examine new style classes.
133
Mark Dickinson8a950712010-04-03 15:47:46 +0000134- Issue #8257: The Decimal construct now accepts a float instance
135 directly, converting that float to a Decimal of equal value:

141
Raymond Hettingera551f312010-04-04 18:34:45 +0000142- the functools module now has a total_ordering() class decorator
Georg Brandl4fabac52010-04-14 08:53:38 +0000143 to simplify the specification of rich comparisons.
Raymond Hettingera551f312010-04-04 18:34:45 +0000144
Raymond Hettingerbb006cf2010-04-04 21:45:01 +0000145- The functools module also adds cmp_to_key() as a tool to transition

Mark Dickinson7c63eee2010-04-02 22:27:36 +0000148- Issue #8294: The Fraction constructor now accepts Decimal and float
149 instances directly.
150
Mark Dickinsone096e822010-04-02 10:17:07 +0000151- Issue #7279: Comparisons involving a Decimal signaling NaN now
152 signal InvalidOperation instead of returning False. (Comparisons
Mark Dickinsonf3eeca12010-04-02 10:35:12 +0000153 involving a quiet NaN are unchanged.) Also, Decimal quiet NaNs
154 are now hashable; Decimal signaling NaNs remain unhashable.
Mark Dickinsone096e822010-04-02 10:17:07 +0000155
Mark Dickinson99d80962010-04-02 08:53:22 +0000156- Issue #2531: Comparison operations between floats and Decimal
157 instances now return a result based on the numeric values of the
158 operands; previously they returned an arbitrary result based on
159 the relative ordering of id(float) and id(Decimal).
160
Barry Warsawf7f2d6f2010-03-31 21:07:16 +0000161- Issue #8233: When run as a script, py_compile.py optionally takes a single
162 argument `-` which tells it to read files to compile from stdin. Each line
163 is read on demand and the named file is compiled immediately. (Original
164 patch by Piotr Ożarowski).
165
166- Issue #3135: Add inspect.getcallargs, which binds arguments to a function
167 like a normal call.
Benjamin Peterson7e213252010-03-30 17:58:13 +0000168
Florent Xicluna58b65662010-03-30 16:29:03 +0000169- Backwards incompatible change: Unicode codepoints line tabulation (0x0B) and
170 form feed (0x0C) are now considered linebreaks, as specified in Unicode
171 Standard Annex #14. See issue #7643.

173
Mark Dickinson9588d992010-03-27 11:14:37 +0000174- Comparisons using one of <, <=, >, >= between a complex instance and
175 a Fractions instance now raise TypeError instead of returning
176 True/False. This makes Fraction <=> complex comparisons consistent with
177 int <=> complex, float <=> complex, and complex <=> complex comparisons.
178
Michael Foorde6410c52010-03-29 20:04:23 +0000179- Addition of ``WeakSet`` to the ``weakref`` module.

190 now silenced.
191
Florent Xicluna9e7a4c92010-03-22 16:07:38 +0000192- Issue #7703: ctypes supports both buffer() and memoryview(). The former is

197
Vinay Sajip804899b2010-03-22 15:29:01 +0000198- logging: Added getChild utility method to Logger and added isEnabledFor
199 method to LoggerAdapter.
200
Vinay Sajip31e928e2010-03-22 13:02:28 +0000201- Issue #8201: logging: Handle situation of non-ASCII and Unicode
202 logger names existing at the same time, causing a Unicode error
203 when configuration code attempted to sort the existing loggers.

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

Georg Brandlba83f822010-03-14 09:50:54 +0000233 for ``TimedRotatingFileHandler`` by using the modification time of an
234 existing log file to compute the next rollover time. If the log file does
235 not exist, the current time is used as the basis for the computation.
Vinay Sajip9098ee42010-03-12 06:01:21 +0000236

246 a base64 transfer-encoded payload *after* decoding it; it no longer does.
247 This is a behavior change, so email's minor version number is now bumped, to

Mark Dickinson4846a8e2010-04-03 14:05:10 +0000274- Issue #8300: When passing a non-integer argument to struct.pack with any
275 integer format code, struct.pack first attempts to convert the non-integer
276 using its __index__ method. If that method is non-existent or raises
277 TypeError it goes on to try the __int__ method, as described below.
278
Georg Brandlba83f822010-03-14 09:50:54 +0000279- Issue #1530559: When passing a non-integer argument to struct.pack with *any*
280 integer format code (one of 'bBhHiIlLqQ'), struct.pack attempts to use the
281 argument's __int__ method to convert to an integer before packing. It also
282 produces a DeprecationWarning in this case. (In Python 2.6, the behaviour
283 was inconsistent: __int__ was used for some integer codes but not for others,
284 and the set of integer codes for which it was used differed between native
285 packing and standard packing.)

531 could crash in many places because of the ``PyByteArray_AS_STRING()`` macro
532 returning NULL. The macro now returns a statically allocated empty string
533 instead.

Georg Brandlba83f822010-03-14 09:50:54 +0000542 (1) a serious 'wrong output' bug that could occur for long (> 40 digit) input
543 strings,
544 (2) a crash in dtoa.c that occurred in debug builds when parsing certain long
545 numeric strings corresponding to subnormal values,
546 (3) a memory leak for some values large enough to cause overflow, and
547 (4) a number of flaws that could lead to incorrectly rounded results.

Georg Brandlba83f822010-03-14 09:50:54 +0000583 file position when calling `truncate()`. It would previously change the file
584 position to the given argument, which goes against the tradition of

681Core and Builtins
682-----------------
683
Georg Brandlba83f822010-03-14 09:50:54 +0000684- The ``__complex__()`` method is now looked up on the class of instances to
685 make it consistent with other special methods.

Antoine Pitrou5b7139a2010-01-02 21:12:58 +0000687- Issue #7462: Implement the stringlib fast search algorithm for the `rfind`,
688 `rindex`, `rsplit` and `rpartition` methods. Patch by Florent Xicluna.
689
Mark Dickinson1b34d252010-01-01 17:27:30 +0000690- Issue #5080: A number of functions and methods previously produced a
Georg Brandlba83f822010-03-14 09:50:54 +0000691 DeprecationWarning when passed a float argument where an integer was expected.
692 These functions and methods now raise TypeError instead. The majority of the
693 effects of this change are in the extension modules, but some core functions
694 and methods are affected: notably the 'chr', 'range' and 'xrange' builtins,
695 and many unicode/str methods.

707
Georg Brandlba83f822010-03-14 09:50:54 +0000708- Issue #1811: Improve accuracy and cross-platform consistency for true division
709 of integers: the result of a/b is now correctly rounded for ints a and b (at
710 least on IEEE 754 platforms), and in particular does not depend on the
711 internal representation of a long.

719
Georg Brandlba83f822010-03-14 09:50:54 +0000720 These executables now work properly with the arch(1) command: ``arch -ppc
721 python`` will start a universal binary version of python in PPC mode (unlike
722 previous releases).

Ronald Oussoren315cd0c2009-11-19 16:25:21 +0000877
Georg Brandlba83f822010-03-14 09:50:54 +0000878- Issue #7117: ``repr(x)`` for a float x returns a result based on the shortest
879 decimal string that's guaranteed to round back to x under correct rounding
880 (with round-half-to-even rounding mode). Previously it gave a string based on
881 rounding x to 17 decimal digits. repr(x) for a complex number behaves
882 similarly. On platforms where the correctly-rounded strtod and dtoa code is
883 not supported (see below), repr is unchanged.
Mark Dickinsonb678de82009-11-19 18:41:49 +0000884
Georg Brandlba83f822010-03-14 09:50:54 +0000885- Issue #7117: On almost all platforms: float-to-string and string-to-float
886 conversions within Python are now correctly rounded. Places these conversions
887 occur include: str for floats and complex numbers; the float and complex
888 constructors; old-style and new-style numeric formatting; serialization and
889 deserialization of floats and complex numbers using marshal, pickle and json;
890 parsing of float and imaginary literals in Python code; Decimal-to-float
891 conversion.
Mark Dickinsonb678de82009-11-19 18:41:49 +0000892
Georg Brandlba83f822010-03-14 09:50:54 +0000893 The conversions use a Python-adapted version of David Gay's well-known dtoa.c,
894 providing correctly-rounded strtod and dtoa C functions. This code is
895 supported on Windows, and on Unix-like platforms using gcc, icc or suncc as
896 the C compiler. There may be a small number of platforms on which correct
897 operation of this code cannot be guaranteed, so the code is not used: notably,
898 this applies to platforms where the C double format is not IEEE 754 binary64,
899 and to platforms on x86 hardware where the x87 FPU is set to 64-bit precision
900 and Python's configure script is unable to determine how to change the FPU
901 precision. On these platforms conversions use the platform strtod and dtoa,
902 as before.

Georg Brandlba83f822010-03-14 09:50:54 +0000904- Issue #7117: Backport round implementation from Python 3.x. ``round()`` now
905 uses the correctly-rounded string <-> float conversions described above (when
906 available), and so produces correctly rounded results that will display nicely
907 under the float repr. There are two related small changes: (1) round now
908 accepts any class with an ``__index__()`` method for its second argument (but
909 no longer accepts floats for the second argument), and (2) an excessively
910 large second integer argument (e.g., ``round(1.234, 10**100)``) no longer
911 raises an exception.

Georg Brandlba83f822010-03-14 09:50:54 +00001058- Issue #5920: For ``float.__format__()``, change the behavior with the empty
1059 presentation type (that is, not one of 'e', 'f', 'g', or 'n') to be like 'g'
1060 but with at least one decimal point and with a default precision
1061 of 12. Previously, the behavior the same but with a default precision of 6.
1062 This more closely matches ``str()``, and reduces surprises when adding
1063 alignment flags to the empty presentation type. This also affects the new
1064 complex.__format__ in the same way.

Georg Brandlba83f822010-03-14 09:50:54 +00001262- Issue #4233: Changed semantic of ``_fileio.FileIO``'s ``close()`` method on
1263 file objects with closefd=False. The file descriptor is still kept open but
1264 the file object behaves like a closed file. The ``FileIO`` object also got a
1265 new readonly attribute ``closefd``.

Georg Brandlba83f822010-03-14 09:50:54 +00001288- On windows, ``os.chdir()`` given unicode was not working if

1290 this code path is really executed because I cannot move to such directory on

Walter Dörwalded960ac2009-05-03 22:36:33 +00001316- Issue #5108: Handle %s like %S and %R in PyUnicode_FromFormatV(): Call
1317 PyUnicode_DecodeUTF8() once, remember the result and output it in a second
1318 step. This avoids problems with counting UTF-8 bytes that ignores the effect
1319 of using the replace error handler in PyUnicode_DecodeUTF8().
1320
Walter Dörwald726ba8e2009-05-06 14:32:35 +00001321- Issue #3739: The unicode-internal encoder now reports the number of characters

1323
Georg Brandlba83f822010-03-14 09:50:54 +00001324- Issue #2422: When compiled with the ``--with-valgrind`` option, the pymalloc

1326 gives improved memory leak detection when running under Valgrind, while taking
1327 advantage of pymalloc at other times.

2494 __long__ method could be packed by 'q', 'Q', '*q', '*Q'; for x with
2495 neither __int__ nor __long__, TypeError used to be raised (with a
2496 confusing error message) for 'I', 'L', '*B', '*H', '*I', '*L', and

Georg Brandlba83f822010-03-14 09:50:54 +00002550 leak-chasing test runs give sensible results. The previous method of reaping
2551 threads could return successfully while some Thread objects were still

2691
Martin v. Löwis9fa5a282008-09-11 06:53:30 +00002692- Issue #3642: Suppress warning in obmalloc when size_t is larger than uint.
2693
Amaury Forgeot d'Arc05e34492008-09-10 22:04:45 +00002694- Issue #3743: In a few places, PY_FORMAT_SIZE_T was incorrectly used with
2695 PyString_FromFormat or PyErr_Format to display size_t values. The macro
2696 PY_FORMAT_SIZE_T is designed to select the correct format for the OS
2697 ``printf`` function, whereas PyString_FromFormat has an independent
2698 implementation and uses "%zd" on all platforms for size_t values.
2699 This makes a difference on win64, where ``printf`` needs "%Id" to display
2700 64bit values.
2701
Benjamin Peterson97179b02008-09-09 20:55:01 +00002702- Issue #3634: _weakref.ref(Exception).__init__() gave invalid return value on
2703 error.
2704
Amaury Forgeot d'Arcd3ffb892008-09-09 07:24:30 +00002705- Issue #3777: long() applied to a float object now always return a long
2706 object; previously an int would be returned for small values. the __long__
2707 method is allowed to return either an int or a long, but the behaviour of
2708 float objects should not change to respect backward compatibility.
2709
Amaury Forgeot d'Arc3571fbf2008-09-01 19:52:00 +00002710- Issue #3751: str.rpartition would perform a left-partition when called with
2711 a unicode argument.

Vinay Sajip35e3b032008-09-01 14:33:59 +00002716 PyArg_ParseTuple and friends, which occurred when the argument for "s*"
Antoine Pitroud4ae97b2008-08-29 18:39:48 +00002717 was correctly parsed but parsing of subsequent arguments failed.
2718
Vinay Sajip35e3b032008-09-01 14:33:59 +00002719- Issue #2534: speed up isinstance() and issubclass() by 50-70%, so as to
Antoine Pitrou0668c622008-08-26 22:42:08 +00002720 match Python 2.5 speed despite the __instancecheck__ / __subclasscheck__
2721 mechanism. In the process, fix a bug where isinstance() and issubclass(),
2722 when given a tuple of classes as second argument, were looking up
2723 __instancecheck__ / __subclasscheck__ on the tuple rather than on each
2724 type object.
2725
Neal Norwitz18aa3882008-08-24 05:04:52 +00002726- Fix crashes on memory allocation failure found with failmalloc.

2728- Fix memory leaks found with valgrind and update suppressions file.
2729
2730- Fix compiler warnings in opt mode which would lead to invalid memory reads.

2795 warnings.catch_warnings() along with some API cleanup. Expanding the tests
2796 for catch_warnings() also led to an improvement in the raising of a

2869-----------------
2870
Guido van Rossumf8402962008-08-20 15:01:50 +00002871- Issue #1878: Remove Py_TPFLAGS_HAVE_VERSION_TAG from
2872 Py_TPFLAGS_DEFAULT when not building the core. This means 3rd party
2873 extensions do not automatically benefit from the class attribute
2874 cache; they will have to explicitly add Py_TPFLAGS_HAVE_VERSION_TAG
2875 to their tp_flags field if they care. This is a backwards
2876 compatibility feature; in 3.0, all types will use the cache by
2877 default.
2878
Benjamin Petersonf647dc12008-08-20 01:27:30 +00002879- Keyword arguments can now follow starred arguments. (``f(a, *args,
2880 keyword=23)`` is now valid syntax.)
2881
Thomas Heller0ad5ae02008-08-19 19:25:04 +00002882- ctypes function pointers that are COM methods have a boolean True
2883 value again.
2884
Martin v. Löwisf91d46a2008-08-12 14:49:50 +00002885- Issue #3139: Make buffer-interface thread-safe wrt. PyArg_ParseTuple,
2886 by denying s# to parse objects that have a releasebuffer procedure,
2887 and introducing s*.
2888
Georg Brandl1e13ea92008-08-11 09:07:59 +00002889- Issue #3537: Fix an assertion failure when an empty but presized dict
2890 object was stored in the freelist.
2891
Mark Dickinsonb6467572008-08-04 21:30:09 +00002892- Issue #1481296: Make long(float('nan')) and int(float('nan')) raise
2893 ValueError consistently across platforms.
2894
Amaury Forgeot d'Arc39fd6722008-07-31 21:28:03 +00002895- Issue #3479: On platforms where sizeof(int) is smaller than sizeof(long)
2896 (64bit Unix, for example), unichr() would truncate its argument and return
2897 u'\x00' for unichr(2**32). Now it properly raises an OverflowError.
2898
Neal Norwitze7d8be82008-07-31 17:17:14 +00002899- Apply security patches from Apple.
2900
Amaury Forgeot d'Arc246daed2008-07-31 00:42:16 +00002901- Issue #2542: Now that issubclass() may call arbitrary code, ensure that
2902 PyErr_ExceptionMatches returns 0 when an exception occurs there.
2903
Antoine Pitrou92f82162008-07-25 22:22:08 +00002904- Issue #1819: function calls with several named parameters are now on
2905 average 35% faster (as measured by pybench).
2906
Amaury Forgeot d'Arce4921fe2008-07-21 22:00:38 +00002907- Issue #2378: An unexpected UnboundLocalError or NameError could appear when
2908 the python debugger steps into a class statement: the free variables (local
2909 variables defined in an outer scope) would be deleted from the outer scope.
2910
Gregory P. Smith0470bab2008-07-22 04:46:32 +00002911- Issue #2620: Overflow checking when allocating or reallocating memory
2912 was not always being done properly in some python types and extension
2913 modules. PyMem_MALLOC, PyMem_REALLOC, PyMem_NEW and PyMem_RESIZE have
2914 all been updated to perform better checks and places in the code that
2915 would previously leak memory on the error path when such an allocation
2916 failed have been fixed.

Amaury Forgeot d'Arc351ffb82008-08-18 19:23:47 +00002926- Issue #2234: distutils failed for some versions of the cygwin compiler. The
2927 version reported by these tools does not necessarily follow the python
2928 version numbering scheme, so the module is less strict when parsing it.
2929
Nick Coghlanf70385a2008-08-18 12:42:46 +00002930- Issue #2235: Added Py3k warnings for types which will become unhashable
2931 under the stricter __hash__ inheritance rules in 3.0. Several types
2932 which did not meet the rules for hash invariants and were already
2933 unhashable in 3.0 have now been explicitly flagged as unhashable in
2934 2.6 as well (collections.Mapping, collections.Set, unittest.TestSuite,
2935 xml.dom.minidom.NamedNodeMap, numbers.Number, UserList.UserList)
2936
Brett Cannon88f801d2008-08-18 00:46:22 +00002937- Update __all__ for cookielib, csv, os, urllib2, and weakref to include things

2947 by using 's*' instead of 't#'.
2948
Mark Dickinson3e4caeb2009-02-21 20:27:01 +00002949- Issue #2222: Fixed reference leak when occurred os.rename()
Hirokazu Yamamoto7f30a682008-08-17 09:46:56 +00002950 fails unicode conversion on 2nd parameter. (windows only)
2951
Facundo Batista94f243a2008-08-17 03:38:39 +00002952- Issue 2464. urllib2 now supports a malformation in the URL received

2959 after a 302 response in the case of not going through a proxy.
2960
Antoine Pitroub90a8be2008-08-15 21:03:21 +00002961- Issue #2676: in the email package, content-type parsing was hanging on
2962 pathological input because of quadratic or exponential behaviour of a
2963 regular expression.
2964
Antoine Pitrou11ec65d2008-08-14 21:04:30 +00002965- Issue #3476: binary buffered reading through the new "io" library is now
2966 thread-safe.
2967
Brett Cannonbf3157b2008-08-14 05:00:03 +00002968- Silence the DeprecationWarning of rfc822 when it is imported by mimetools
2969 since mimetools itself is deprecated. Because modules are cached, all
2970 subsequent imports of rfc822 will not raise a visible DeprecationWarning.
2971
Antoine Pitrou9fcd4b32008-08-11 17:21:36 +00002972- Issue #3134: shutil referenced undefined WindowsError symbol.

2978 version that did not raise a DeprecationWarning under -3.
2979

2984 to _sre.compile() will now be rejected. This should not affect anybody
2985 since the re.compile() function never generates invalid re-bytecode.
2986
Skip Montanaroa032bf42008-08-08 22:52:51 +00002987- Issue #3436: Make csv.DictReader's fieldnames attribute a property so that
2988 upon first access it can be automatically initialized from the csv file if
2989 it wasn't initialized during instantiation.
2990
Brett Cannon3aa2a492008-08-06 22:28:09 +00002991- Issue #2338: Create imp.reload() to help with transitioning to Python 3.0 as
2992 the reload() built-in has been removed.
2993
Brett Cannon7e30b672008-08-04 21:52:25 +00002994- Changed code in the following modules/packages to remove warnings raised
Brett Cannonc1b76e42008-08-09 23:06:16 +00002995 while running under the ``-3`` flag: aifc, asynchat, asyncore, bdb, bsddb,

3003 raised an AttributeError.
3004
Benjamin Peterson01a24322008-07-28 23:35:27 +00003005- Issue #2523: Fix quadratic behaviour when read()ing a binary file without
Antoine Pitroude781a42008-08-09 12:43:23 +00003006 asking for a specific length. This problem only affected files opened
3007 using the new "io" module, not the built-in open() function.
Benjamin Peterson01a24322008-07-28 23:35:27 +00003008

Antoine Pitrou5fdfa3e2008-07-25 19:42:26 +00003032- Issue #3394: zipfile.writestr sets external attributes when passed a
3033 file name rather than a ZipInfo instance, so files are extracted with
3034 mode 0600 rather than 000 under Unix.
3035
Gregory P. Smitha36f8fe2008-08-04 00:13:29 +00003036- Issue #1857: subprocess.Popen.poll gained an additional _deadstate keyword

Nick Coghlan6e8fef02008-08-18 13:14:22 +00003048- Issue #2235: the C API function PyObject_HashNotImplemented and its
3049 interaction with the tp_hash slot (added in 2.6b2) are now documented
3050
Nick Coghlan2a0c2b12008-08-04 12:47:17 +00003051- Issue #643841: The language reference now provides more detailed
3052 coverage of the lookup process for special methods. The disclaimers
3053 regarding lack of coverage of new-style classes have also been
3054 removed, since the coverage is now fairly reasonable.

Raymond Hettingere3ae6552008-06-20 04:18:15 +00003057What's New in Python 2.6 beta 2?
3058================================
3059
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00003060*Release date: 17-Jul-2008*
3061
Raymond Hettingere3ae6552008-06-20 04:18:15 +00003062Core and Builtins
3063-----------------
3064
Georg Brandl3e483f62008-07-16 22:57:41 +00003065- Issue #3156: Fix inconsistent behavior of the bytearray type: all
3066 its methods now allow for items objects that can be converted to
3067 an integer using operator.index().
3068
Mark Dickinson64b7e502008-07-16 09:40:03 +00003069- Issue #3360: Fix incorrect parsing of '020000000000.0', which
3070 produced a ValueError instead of giving the correct float.
3071
Eric Smitha5fa5a22008-07-16 00:11:49 +00003072- Issue #3083: Add alternate (#) formatting for bin, oct, hex output
3073 for str.format(). This adds the prefix 0b, 0o, or 0x, respectively.
3074
Mark Dickinson7103aa42008-07-15 19:08:33 +00003075- Issue #3008: the float type has a new instance method 'float.hex'
3076 and a new class method 'float.fromhex' to convert floating-point
3077 numbers to and from hexadecimal strings, respectively.
3078
Nick Coghlan6d6bd442008-07-15 15:40:22 +00003079- Issue #2235: __hash__ is once again inherited by default. To allow
3080 collections.Hashable to remain meaningful in the presence of the
3081 default hash implementation (object.__hash__), it is now possible
3082 to explicit block inheritance of hash by setting __hash__=None at
3083 the Python level, or tp_hash=PyObject_HashNotImplemented at the C
3084 level.
3085
Nick Coghlanb028f502008-07-13 14:52:36 +00003086- Issue #3221: Issue a RuntimeWarning instead of raising SystemError if
3087 the parent module cannot be found while performing an absolute import.
3088 This means that an incorrectly defined __package__ attribute will
3089 now only prevent relative imports in that module rather than causing
3090 all imports from that module to fail.
3091
Nick Coghlan14ff9942008-07-08 14:21:42 +00003092- Issue #2517: Allow unicode messages in Exceptions again by correctly
3093 bypassing the instance dictionary when looking up __unicode__ on
3094 new-style classes.
3095
Amaury Forgeot d'Arcbdd941f2008-07-01 20:38:04 +00003096- Issue #3242: Fix a crash inside the print statement, if sys.stdout is
3097 set to a custom object whose write() method happens to install
3098 another file in sys.stdout.
3099
Amaury Forgeot d'Arc1f40c8a2008-06-30 22:42:40 +00003100- Issue #3088: Corrected a race condition in classes derived from
3101 threading.local: the first member set by a thread could be saved in
3102 another thread's dictionary.
3103
Mark Dickinson1ec2fcd2008-06-20 14:53:43 +00003104- Issue #3004: Minor change to slice.indices(): the start and stop
3105 arguments are now treated identically, making the behaviour easier
3106 to describe and understand. For example, slice(None, -10,
3107 1).indices(9) now returns (0, 0, 1) instead of (0, -1, 1), and
3108 slice(None, 10, -1).indices(10) returns (9, 9, -1) instead of (9,
3109 10, -1).
3110
Georg Brandl278fc502008-07-19 12:46:12 +00003111- Issue #3219: Calling a function with repeated keyword arguments,
3112 f(a=2, a=23), would not cause a syntax error. This was a regression
3113 from 2.4 caused by the switch to the new compiler.
Benjamin Peterson175e4d92008-07-01 19:34:52 +00003114
Georg Brandl278fc502008-07-19 12:46:12 +00003115- Issue #2862: Make int and float freelist management consistent with
3116 other freelists. Changes their CompactFreeList apis into
3117 ClearFreeList apis and calls them via gc.collect().
Gregory P. Smith2fe77062008-07-06 03:35:58 +00003118

3120-------
3121
Thomas Heller57adf222008-08-14 19:10:48 +00003122- Issue #3554: ctypes.string_at and ctypes.wstring_at did call Python
3123 api functions without holding the GIL, which could lead to a fatal
3124 error when they failed.
3125
Martin v. Löwisaabf4042008-08-02 07:20:25 +00003126- Issue #799428: Fix Tkinter.Misc._nametowidget to unwrap Tcl command objects.

3135 ForkingPickler.register() to resolve conflict with ctypes.
3136
Vinay Sajip51e65192008-07-18 09:01:10 +00003137- Issue #3090: Fixed ARCHFLAGS parsing on OS/X

Thomas Heller880f5292008-07-15 19:39:38 +00003139- Issue #3313: Fixed a crash when a failed dlopen() call does not set
3140 a valid dlerror() message.
3141
Thomas Heller2bad6572008-07-15 17:19:50 +00003142- Issue #3258: Fixed a crash when a ctypes POINTER type to an
3143 incomplete structure was created.
3144

3148
Andrew M. Kuchlingcc3f2b12008-07-10 14:43:31 +00003149- Issue #3301: Bisect module behaved badly when lo was negative.
Raymond Hettinger3cd1e422008-07-10 14:03:19 +00003150
Amaury Forgeot d'Arc0f7cddc2008-07-06 21:34:39 +00003151- Issue #839496: SimpleHTTPServer used to open text files in text mode. This is
3152 both unnecessary (HTTP allows text content to be sent in several forms) and
Andrew M. Kuchlingcc3f2b12008-07-10 14:43:31 +00003153 wrong because the actual transmitted size could differ from the
Amaury Forgeot d'Arc0f7cddc2008-07-06 21:34:39 +00003154 content-length. The problem had been corrected in the 2.4 branch, but never
3155 merged into trunk.
3156
Georg Brandle78fbcc2008-07-05 10:13:36 +00003157- Issue #2663: add filtering capability to shutil.copytree().

Nick Coghlanc060b0e2008-07-02 13:09:19 +00003170- Issue #3190: Pydoc now hides the automatic module attribute __package__ (the
3171 handling is now the same as that of other special attributes like __name__).
3172
Brett Cannon8bb8fa52008-07-02 01:57:08 +00003173- Issue #2885 (partial): The urllib.urlopen() function has been deprecated for
3174 removal in Python 3.0 in favor of urllib2.urlopen().

3562 mode or even as a 4-way universal binary (that is, PPC, i386,
Georg Brandl5cc774e2008-06-11 20:28:06 +00003563 PPC64 and x86_64 support in one binary).
Ronald Oussoren5640ce22008-06-05 12:58:24 +00003564
3565 This is controlled by the configure argument ``--with-universal-archs``:
3566
3567 - ``--with-universal-archs=all``: install 4-way universal
3568
3569 - ``--with-universal-archs=32-bit``: install 2-way universal, 32-bit (the default)
3570
3571 - ``--with-universal-archs=64-bit``: install 2-way universal, 64-bit
3572
3573 This option should be used in combination with ``--enable-universalsdk=``.
3574
3575 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 +00003625- Issue #1631171: Re-implement the 'warnings' module in C (the
3626 original Python code has been kept as backup). This will allow for
3627 using the 'warning's machinery in such places as the parser where
3628 use of pure Python code is not possible. Both the ``showarning()``
3629 and ``formatwarning()`` gain an optional 'line' argument which is
3630 not called by default for backwards-compatibility reasons. Setting
3631 ``warnings.showwarning()`` to an implementation that lacks support
3632 for the ``line`` argument will raise a DeprecationWarning.

Georg Brandl3ee81df2008-05-17 18:14:43 +00003695- Issue #2550: The approach used by client/server code for obtaining
3696 ports to listen on in network-oriented tests has been refined in an
3697 effort to facilitate running multiple instances of the entire
3698 regression test suite in parallel without issue.
3699 test_support.bind_port() has been fixed such that it will always
3700 return a unique port -- which wasn't always the case with the
3701 previous implementation, especially if socket options had been set
3702 that affected address reuse (i.e. SO_REUSEADDR, SO_REUSEPORT). The
3703 new implementation of bind_port() will actually raise an exception
3704 if it is passed an AF_INET/SOCK_STREAM socket with either the
3705 SO_REUSEADDR or SO_REUSEPORT socket option set. Furthermore, if
3706 available, bind_port() will set the SO_EXCLUSIVEADDRUSE option on
3707 the socket it's been passed. This currently only applies to
3708 Windows. This option prevents any other sockets from binding to the
3709 host/port we've bound to, thus removing the possibility of the
3710 'non-deterministic' behaviour, as Microsoft puts it, that occurs
3711 when a second SOCK_STREAM socket binds and accepts to a host/port
3712 that's already been bound by another socket. The optional preferred
3713 port parameter to bind_port() has been removed. Under no
3714 circumstances should tests be hard coding ports!
3715
3716 test_support.find_unused_port() has also been introduced, which will
3717 pass a temporary socket object to bind_port() in order to obtain an
3718 unused port. The temporary socket object is then closed and
3719 deleted, and the port is returned. This method should only be used
3720 for obtaining an unused port in order to pass to an external program
3721 (i.e. the -accept [port] argument to openssl's s_server mode) or as
3722 a parameter to a server-oriented class that doesn't give you direct
3723 access to the underlying socket used.
3724
3725 Finally, test_support.HOST has been introduced, which should be used
3726 for the host argument of any relevant socket calls (i.e. bind and
3727 connect).
Trent Nelsone41b0062008-04-08 23:47:30 +00003728
3729 The following tests were updated to following the new conventions:
Georg Brandl3ee81df2008-05-17 18:14:43 +00003730 test_socket, test_smtplib, test_asyncore, test_ssl, test_httplib,
Trent Nelsone41b0062008-04-08 23:47:30 +00003731 test_poplib, test_ftplib, test_telnetlib, test_socketserver,
3732 test_asynchat and test_socket_ssl.
3733
Georg Brandl3ee81df2008-05-17 18:14:43 +00003734 It is now possible for multiple instances of the regression test
3735 suite to run in parallel without issue.

Amaury Forgeot d'Arc9a0d3462008-03-23 09:55:29 +00003789- Issue #1477: With narrow Unicode builds, the unicode escape sequence
Georg Brandl3ee81df2008-05-17 18:14:43 +00003790 \Uxxxxxxxx did not accept values outside the Basic Multilingual
3791 Plane. This affected raw unicode literals and the
3792 'raw-unicode-escape' codec. Now UTF-16 surrogates are generated in
3793 this case, like normal unicode literals and the 'unicode-escape'
3794 codec.

4013
Eric Smitha73fbe72008-02-23 03:09:44 +00004014- Added the future_builtins module, which contains hex() and oct().
4015 These are the PEP 3127 version of these functions, designed to be
4016 compatible with the hex() and oct() builtins from Python 3.0. They
4017 differ slightly in their output formats from the existing, unchanged
4018 Python 2.6 builtins. The expected usage of the future_builtins
4019 module is:

4021
Eric Smith7ef40bf2008-02-20 23:34:22 +00004022- Issue #1600: Modifed PyOS_ascii_formatd to use at most 2 digit
4023 exponents for exponents with absolute value < 100. Follows C99
4024 standard. This is a change on Windows, which would use 3 digits.
4025 Also, added 'n' to the formats that PyOS_ascii_formatd understands,
4026 so that any alterations it does to the resulting string will be
4027 available in stringlib/formatter.h (for float.__format__).
4028
Eric Smith5a3c1352008-02-19 13:21:56 +00004029- Implemented PEP 3101, Advanced String Formatting. This adds a new
4030 builtin format(); a format() method for str and unicode; a
4031 __format__() method to object, str, unicode, int, long, float, and
4032 datetime; the class string.Formatter; and the C API
4033 PyObject_Format().
4034
Georg Brandl3ee81df2008-05-17 18:14:43 +00004035- Fixed several potential crashes, all caused by specially crafted
4036 __del__ methods exploiting objects in temporarily inconsistent
4037 state.
Amaury Forgeot d'Arc632fad32008-02-16 20:55:24 +00004038
Vinay Sajipb7edfc42008-04-02 21:10:23 +00004039- Issue #2115: Important speedup in setting __slot__ attributes. Also
Georg Brandl3ee81df2008-05-17 18:14:43 +00004040 prevent a possible crash: an Abstract Base Class would try to access
4041 a slot on a registered virtual subclass.
Amaury Forgeot d'Arc60d6c7f2008-02-15 21:22:45 +00004042

Georg Brandl3ee81df2008-05-17 18:14:43 +00004046- Clear all free lists during a gc.collect() of the highest generation
4047 in order to allow pymalloc to free more arenas. Python may give back
4048 memory to the OS earlier.
Christian Heimes3b718a72008-02-14 12:47:33 +00004049
Georg Brandl3ee81df2008-05-17 18:14:43 +00004050- Issue #2045: Fix an infinite recursion triggered when printing a
4051 subclass of collections.defaultdict, if its default_factory is set
4052 to a bound method.

Georg Brandl3ee81df2008-05-17 18:14:43 +00004080- Patch #1473257: generator objects gain a gi_code attribute. This is
4081 the same object as the func_code attribute of the function that
4082 produced the generator.
Georg Brandl0cdf9a32008-01-26 14:14:20 +00004083
Georg Brandl3ee81df2008-05-17 18:14:43 +00004084- Issue #1920: "while 0" statements were completely removed by the
4085 compiler, even in the presence of an "else" clause, which is
4086 supposed to be run when the condition is false. Now the compiler
4087 correctly emits bytecode for the "else" suite.
Amaury Forgeot d'Arc31eaafe2008-01-24 22:59:25 +00004088
Guido van Rossumeead05f2008-01-24 18:21:02 +00004089- A few crashers fixed: weakref_in_del.py (issue #1377858);
4090 loosing_dict_ref.py (issue #1303614, test67.py);
4091 borrowed_ref_[34].py (not in tracker).
4092
Vinay Sajipd7cf32e2008-01-24 12:43:33 +00004093- Issue #1069410: The "can't load dll" message box on Windows is
Christian Heimesb2302ba2008-01-23 17:15:06 +00004094 suppressed while an extension is loaded by calling SetErrorMode in

4096
Georg Brandl3ee81df2008-05-17 18:14:43 +00004097- Issue #1915: Python compiles with --enable-unicode=no again. However
Christian Heimes082c9b02008-01-23 14:20:50 +00004098 several extension methods and modules do not work without unicode
4099 support.
4100
Georg Brandl26543b12008-01-21 18:36:51 +00004101- Issue #1882: when compiling code from a string, encoding cookies in the

4105
Georg Brandl6caad7d2008-01-26 14:19:22 +00004106- Issue #1865: ``bytes`` as an alias for ``str`` and b"" as an alias "" were
Christian Heimes288e89a2008-01-18 18:24:07 +00004107 added.
4108
Christian Heimesc94e2b52008-01-14 04:13:37 +00004109- sys.float_info / PyFloat_GetInfo: The floating point information
4110 object was converted from a dict to a specialized structseq object.
4111
Georg Brandl3ee81df2008-05-17 18:14:43 +00004112- Patch #1816: Added sys.flags structseq. It exposes the status of
4113 most command line arguments and PYTHON* environment variables.
Christian Heimesf31b69f2008-01-14 03:42:48 +00004114
Georg Brandl3ee81df2008-05-17 18:14:43 +00004115- Objects/structseq.c: Implemented new structseq representation. The
4116 patch makes structseqs (e.g. the return value of os.stat) more
4117 readable.
Christian Heimes9c201962008-01-14 03:33:52 +00004118
Georg Brandl3ee81df2008-05-17 18:14:43 +00004119- Patch #1700288: added a type attribute cache that caches method
4120 accesses, resulting in speedups in heavily object-oriented code.
Amaury Forgeot d'Arce4c270c2008-01-14 00:29:41 +00004121
Neal Norwitz3fc15b82008-01-10 05:42:58 +00004122- Bug #1776: __import__() no longer accepts filenames on any platform.

4128 envvar and sys.dont_write_bytecode attribute. All these can be set
4129 to forbid Python to attempt to write compiled bytecode files.
Georg Brandl2da0fce2008-01-07 17:09:35 +00004130
Georg Brandl3ee81df2008-05-17 18:14:43 +00004131- Improve some exception messages when Windows fails to load an
4132 extension module. Now we get for example '%1 is not a valid Win32
4133 application' instead of 'error code 193'.

4190
Georg Brandl21e99f42010-03-07 15:23:59 +00004191- The enumerate() built-in function is no longer bounded to sequences
Georg Brandl3ee81df2008-05-17 18:14:43 +00004192 smaller than LONG_MAX. Formerly, it raised an OverflowError. Now,
4193 automatically shifts from ints to longs.
Raymond Hettinger8f669372007-10-03 21:18:11 +00004194
Georg Brandl3ee81df2008-05-17 18:14:43 +00004195- Issue #1686386: Tuple's tp_repr did not take into account the
4196 possibility of having a self-referential tuple, which is possible
4197 from C code. Nor did object's tp_str consider that a type's tp_str
4198 could do something that could lead to an inifinite recursion.
4199 Py_ReprEnter() and Py_EnterRecursiveCall(), respectively, fixed the
4200 issues.
Brett Cannon0b14f242007-09-30 19:45:10 +00004201
Georg Brandl3ee81df2008-05-17 18:14:43 +00004202- Issue #1164: It was possible to trigger deadlock when using the
4203 'print' statement to write to a file since the GIL was not released
4204 as needed. Now PyObject_Print() does the right thing along with
4205 various tp_print implementations of the built-in types and those in
4206 the collections module.
Brett Cannon01531592007-09-17 03:28:34 +00004207
Georg Brandl3ee81df2008-05-17 18:14:43 +00004208- Issue #1147: Exceptions were directly allowing string exceptions in

Georg Brandl3ee81df2008-05-17 18:14:43 +00004216 PyObject_Call() never calling back out to Python code to trigger
4217 recursion depth updates/checks. Required the creation of a static
4218 RuntimeError instance in case normalizing an exception put the
4219 recursion check value past its limit. Fixes crashers

Georg Brandl5cb76c12007-03-21 09:00:39 +00004263- Patch #1682205: a TypeError while unpacking an iterable is no longer
4264 masked by a generic one with the message "unpack non-sequence".

Guido van Rossum143b5642007-03-23 04:58:42 +00004268- Bug #1683368: The object.__init__() and object.__new__() methods are
4269 now stricter in rejecting excess arguments. The only time when
4270 either allows excess arguments is when it is not overridden and the
4271 other one is. For backwards compatibility, when both are
4272 overridden, it is a deprecation warning (for now; maybe a Py3k
Guido van Rossum234b1ff2007-03-23 19:39:01 +00004273 warning later). Also, type.__init__() insists on the same signature
4274 as supported by type.__new__().

Georg Brandl3ee81df2008-05-17 18:14:43 +00004276- Patch #1675423: PyComplex_AsCComplex() now tries to convert an
4277 object to complex using its __complex__() method before falling back
4278 to the __float__() method. Therefore, the functions in the cmath
4279 module now can operate on objects that define a __complex__()
4280 method.

Georg Brandl7b9c5552007-03-12 14:30:05 +00004298- Bug #1678647: write a newline after printing an exception in any
4299 case, even when converting the value to a string failed.
4300
Georg Brandl871f1bc2007-03-12 13:17:36 +00004301- The dir() function has been extended to call the __dir__() method on
Georg Brandl3ee81df2008-05-17 18:14:43 +00004302 its argument, if it exists. If not, it will work like before. This
4303 allows customizing the output of dir() in the presence of a
4304 __getattr__().

4314 raising a ValueError.

Georg Brandlaa2321b2007-03-07 00:40:28 +00004316- Patch #703779: unset __file__ in __main__ after running a file. This
Georg Brandl3ee81df2008-05-17 18:14:43 +00004317 makes the filenames the warning module prints much more sensible
4318 when a PYTHONSTARTUP file is used.

4332 sq_ass_slice instead of the sq_slice slot.
4333
Georg Brandl3ee81df2008-05-17 18:14:43 +00004334- When printing an unraisable error, don't print exceptions. before
4335 the name. This duplicates the behavior whening normally printing

4345 created a weakref on itself during a __del__ call for new-style
4346 classes (classic classes still have the bug).

Georg Brandl2c1375c2006-10-12 11:27:59 +00004386- Bug #1545497: when given an explicit base, int() did ignore NULs
4387 embedded in the string to convert.
4388
Georg Brandl846f73a2006-10-08 07:11:54 +00004389- Bug #1569998: break inside a try statement (outside a loop) is now

Georg Brandl4e933132006-09-06 20:05:58 +00004419- Bug #1542051: Exceptions now correctly call PyObject_GC_UnTrack.

Georg Brandl3ee81df2008-05-17 18:14:43 +00004437 generator expressions (x for x, in ... ) works again. Fixing this
4438 problem required changing the .pyc magic number. This means that
4439 .pyc files generated before 2.5c2 will be regenerated.

Georg Brandl3ee81df2008-05-17 18:14:43 +00005242- The implementation of UnicodeError objects has been simplified
5243 (start and end attributes are now stored directly as Py_ssize_t
5244 members).
Walter Dörwald84a3efe2007-06-13 16:57:12 +00005245
Georg Brandl3ee81df2008-05-17 18:14:43 +00005246- Issue #829951: In the smtplib module, SMTP.starttls() now complies
5247 with RFC 3207 and forgets any knowledge obtained from the server not
5248 obtained from the TLS negotiation itself. Patch contributed by Bill
5249 Fenner.
Gregory P. Smith2b3ba582008-01-17 08:03:17 +00005250
Georg Brandl3ee81df2008-05-17 18:14:43 +00005251- Issue #1339: The smtplib.SMTP class has been refactored a bit such
Gregory P. Smithbde4ae42008-01-17 08:35:49 +00005252 that the SMTP.starttls() caller no longer needs to call ehlo()
5253 beforehand. SMTP.starttls() now raises an exception of the server
Georg Brandl3ee81df2008-05-17 18:14:43 +00005254 does not claim to support starttls. Adds the
5255 SMTP.ehlo_or_helo_if_needed() method. Patch contributed by Bill
5256 Fenner.

Georg Brandl3ee81df2008-05-17 18:14:43 +00005298- Patch #976880: ``mmap`` objects now have an ``rfind`` method that
Andrew M. Kuchling5c60bfc2008-01-19 18:18:41 +00005299 works as expected. ``mmap.find`` also takes an optional ``end``
5300 parameter.

5325 contents before adding elements from the iterable. This fix brings
5326 the behavior into line with that for list.__init__().
Raymond Hettingeradf9ffd2007-12-13 00:08:37 +00005327
Georg Brandl3ee81df2008-05-17 18:14:43 +00005328- Added wide char functions to msvcrt module: getwch, getwche, putwch

5334
Georg Brandl3ee81df2008-05-17 18:14:43 +00005335- Marshal.dumps() now expects exact type matches for int, long, float,
5336 complex, tuple, list, dict, set, and frozenset. Formerly, it would
5337 silently miscode subclasses of those types. Now, it raises a
5338 ValueError instead.
Raymond Hettinger12e94202007-11-07 01:13:09 +00005339

Georg Brandl3ee81df2008-05-17 18:14:43 +00005354 time so that opening a database previously created with the DB_DUP
5355 or DB_DUPSORT flag set will keep the proper behavior on subsequent
5356 opens. Specifically: dictionary assignment to a DB object will
5357 replace all values for a given key when the database allows
5358 duplicate values. DB users should use DB.put(k, v) when they want
5359 to store duplicates; not DB[k] = v.
Gregory P. Smithec10a4a2007-11-05 02:32:26 +00005360

5366 characters with ASCII value less than 32. Also, it correctly quotes
5367 dots only if they occur on a single line, as opposed to the previous
5368 behavior of quoting dots if they are the second character of any
5369 line.
Georg Brandl4aef7272007-03-13 22:49:43 +00005370

Georg Brandl3ee81df2008-05-17 18:14:43 +00005775- Removed the macfs module. It had been deprecated since Python 2.5.
5776 This lead to the deprecation of macostools.touched() as it relied
5777 solely on macfs and was a no-op under OS X.
