16
Mark Dickinsona8d26682010-05-04 16:18:25 +000017- Issue #1533: fix inconsistency in range function argument
18 processing: any non-float non-integer argument is now converted to
19 an integer (if possible) using its __int__ method. Previously, only
20 small arguments were treated this way; larger arguments (those whose
21 __int__ was outside the range of a C long) would produce a TypeError.
22
Nick Coghlanc5e44852010-04-28 14:51:08 +000023- Issue #8202: sys.argv[0] is now set to '-m' instead of '-c' when
24 searching for the module file to be executed with the -m command
25 line option

30 PyMarshal_ReadLastObjectFromFile, which doesn't bring any noticeable
31 benefit compared to the dynamic memory allocation fallback. Patch by
32 Charles-François Natali.
33
Benjamin Peterson821a8ea2010-04-16 22:35:38 +000034- Issue #8417: Raise an OverflowError when an integer larger than sys.maxsize is
35 passed to bytearray.

53 ASCII with backslashreplace error handler if str(value) failed
54
Mark Dickinson4f96f5f2010-05-04 14:25:50 +000055- Issue #8567: Fix precedence of signals in Decimal module: when a
56 Decimal operation raises multiple signals and more than one of those
57 signals is trapped, the specification determines the order in which
58 the signals should be handled. In many cases this order wasn't
59 being followed, leading to the wrong Python exception being raised.
60
Antoine Pitrouf7fd8e42010-05-03 16:25:33 +000061- Issue #7865: The close() method of :mod:`io` objects should not swallow

72
Tarek Ziadéa5cd1822010-04-30 12:15:12 +000073- Issue #8577: distutils.sysconfig.get_python_inc() now makes a difference
74 between the build dir and the source dir when looking for "python.h" or
75 "Include".
76
Lars Gustäbel5c4c4612010-04-29 15:23:38 +000077- Issue #8464: tarfile no longer creates files with execute permissions set
78 when mode="w|" is used.

87 suites, the IGNORE_EXCEPTION_DETAIL directive now also ignores the module
Nick Coghlan54677da2010-04-28 14:34:30 +000088 location of the raised exception. Based on initial patch by Lennart
89 Regebro.

103 where the method could block indefinitely if called just before the
104 event loop started running. This also fixes the occasional freezes
105 witnessed in test_httpservers.
106
Antoine Pitroufc69af12010-04-24 20:04:58 +0000107- Issue #5103: SSL handshake would ignore the socket timeout and block
108 indefinitely if the other end didn't respond.
109
Antoine Pitrou4d3e3722010-04-24 19:57:01 +0000110- The do_handshake() method of SSL objects now adjusts the blocking mode of
111 the SSL structure if necessary (as other methods already do).
112
Georg Brandl4341e542010-04-24 09:08:10 +0000113- Issue #7507: Quote "!" in pipes.quote(); it is special to some shells.
114
Antoine Pitroub558f172010-04-23 23:25:45 +0000115- Issue #5238: Calling makefile() on an SSL object would prevent the
116 underlying socket from being closed until all objects get truely destroyed.
117
Antoine Pitroudfb299b2010-04-23 22:54:59 +0000118- Issue #7943: Fix circular reference created when instantiating an SSL
119 socket. Initial patch by Péter Szabó.
120
Sean Reifscheiderf6ce3cb2010-04-23 08:31:55 +0000121- Issue #8451: Syslog module now uses basename(sys.argv[0]) instead of
122 the string "python" as the *ident*. openlog() arguments are all optional
123 and keywords.
124
Antoine Pitroua5c4b552010-04-22 23:33:02 +0000125- Issue #8108: Fix the unwrap() method of SSL objects when the socket has
126 a non-infinite timeout. Also make that method friendlier with applications
127 wanting to continue using the socket in clear-text mode, by disabling
128 OpenSSL's internal readahead. Thanks to Darryl Miles for guidance.
129
Antoine Pitrouc715a9e2010-04-21 19:28:03 +0000130- Issue #8484: Load all ciphers and digest algorithms when initializing
131 the _ssl extension, such that verification of some SSL certificates
132 doesn't fail because of an "unknown algorithm".
133
Victor Stinnera92e81b2010-04-20 22:28:31 +0000134- Issue #8437: Fix test_gdb failures, patch written by Dave Malcolm

156 filename and date, conforming to the 'standards' they were originally
157 designed to follow. This improves compatibility with patch tools.
158
R. David Murray27ef9372010-04-12 14:26:06 +0000159- Issue #7472: Fixed typo in email.encoders module; messages using ISO-2022

195 (Optimization was unintentionally turned on in gcc --with-pydebug builds in
196 2.7 beta1 as a result of the issue #1628484 fix, combined with autoconf's
197 strange choice of default CFLAGS produced by AC_PROG_CC for gcc.)
198

217
Philip Jenveyaebbaeb2010-04-06 23:24:45 +0000218- Issue #7301: Add environment variable $PYTHONWARNINGS.
219
Benjamin Peterson3a1dfa22010-04-06 21:50:00 +0000220- Issue #8329: Don't return the same lists from select.select when no fds are
221 changed.
222
Mark Dickinson82791672010-04-06 16:47:55 +0000223- Issue #8259: 1L << (2**31) no longer produces an 'outrageous shift error'
224 on 64-bit machines. The shift count for either left or right shift is
225 permitted to be up to sys.maxsize.
226
Benjamin Peterson4ceeeb02010-04-03 22:48:51 +0000227- Ensure that tokenization of identifiers is not affected by locale.

Eric Smithd44b2fc2010-04-02 12:30:56 +0000233- Issue #7994: Issue a PendingDeprecationWarning if object.__format__
234 is called with a non-empty format string. This is an effort to
235 future-proof user code. If a derived class does not currently
236 implement __format__ but later adds its own __format__, it would
237 most likely break user code that had supplied a format string. This
238 will be changed to a DeprecationWaring in Python 3.3 and it will be
239 an error in Python 3.4.

Benjamin Peterson96545892010-03-21 20:21:00 +0000249- Issue #6474: Make error message from passing an inadequate number of keyword
250 arguments to a function correct.
251

253
Victor Stinner66644262010-03-10 22:30:19 +0000254- Issue #3137: Don't ignore errors at startup, especially a keyboard interrupt
Georg Brandlba83f822010-03-14 09:50:54 +0000255 (SIGINT). If an error occurs while importing the site module, the error is

265
Antoine Pitrouf9de5342010-04-05 21:35:07 +0000266- Issue #8321: Give access to OpenSSL version numbers from the `ssl` module,
267 using the new attributes `ssl.OPENSSL_VERSION`, `ssl.OPENSSL_VERSION_INFO`
268 and `ssl.OPENSSL_VERSION_NUMBER`.
269

273 directly, converting that float to a Decimal of equal value:
274
275 >>> Decimal(1.1)

279
Raymond Hettingera551f312010-04-04 18:34:45 +0000280- the functools module now has a total_ordering() class decorator
Georg Brandl4fabac52010-04-14 08:53:38 +0000281 to simplify the specification of rich comparisons.
Raymond Hettingera551f312010-04-04 18:34:45 +0000282
Raymond Hettingerbb006cf2010-04-04 21:45:01 +0000283- The functools module also adds cmp_to_key() as a tool to transition
Raymond Hettingera551f312010-04-04 18:34:45 +0000284 old-style comparison functions to new-style key-functions.
285
Mark Dickinson7c63eee2010-04-02 22:27:36 +0000286- Issue #8294: The Fraction constructor now accepts Decimal and float
287 instances directly.

Mark Dickinsone096e822010-04-02 10:17:07 +0000289- Issue #7279: Comparisons involving a Decimal signaling NaN now
290 signal InvalidOperation instead of returning False. (Comparisons
Mark Dickinsonf3eeca12010-04-02 10:35:12 +0000291 involving a quiet NaN are unchanged.) Also, Decimal quiet NaNs
292 are now hashable; Decimal signaling NaNs remain unhashable.
Mark Dickinsone096e822010-04-02 10:17:07 +0000293
Mark Dickinson99d80962010-04-02 08:53:22 +0000294- Issue #2531: Comparison operations between floats and Decimal

296 operands; previously they returned an arbitrary result based on
297 the relative ordering of id(float) and id(Decimal).
298
Barry Warsawf7f2d6f2010-03-31 21:07:16 +0000299- Issue #8233: When run as a script, py_compile.py optionally takes a single
300 argument `-` which tells it to read files to compile from stdin. Each line
301 is read on demand and the named file is compiled immediately. (Original
302 patch by Piotr Ożarowski).
303
304- Issue #3135: Add inspect.getcallargs, which binds arguments to a function

415 integer format code, struct.pack first attempts to convert the non-integer
416 using its __index__ method. If that method is non-existent or raises
417 TypeError it goes on to try the __int__ method, as described below.
418
Georg Brandlba83f822010-03-14 09:50:54 +0000419- Issue #1530559: When passing a non-integer argument to struct.pack with *any*
420 integer format code (one of 'bBhHiIlLqQ'), struct.pack attempts to use the
421 argument's __int__ method to convert to an integer before packing. It also
422 produces a DeprecationWarning in this case. (In Python 2.6, the behaviour
423 was inconsistent: __int__ was used for some integer codes but not for others,
424 and the set of integer codes for which it was used differed between native
425 packing and standard packing.)

Antoine Pitrouf3fa0742010-01-31 22:26:04 +0000722- Issue #6939: Fix file I/O objects in the `io` module to keep the original
Georg Brandlba83f822010-03-14 09:50:54 +0000723 file position when calling `truncate()`. It would previously change the file
724 position to the given argument, which goes against the tradition of
Antoine Pitrouf3fa0742010-01-31 22:26:04 +0000725 ftruncate() and other truncation APIs. Patch by Pascal Chambon.

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

Georg Brandlba83f822010-03-14 09:50:54 +0000744- Issue #7748: Since unicode values are supported for some metadata options in

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

Benjamin Peterson4f51baf2009-12-05 18:40:02 +0000816What's New in Python 2.7 alpha 2?
817=================================

821Core and Builtins
822-----------------
823
Georg Brandlba83f822010-03-14 09:50:54 +0000824- The ``__complex__()`` method is now looked up on the class of instances to
825 make it consistent with other special methods.
Benjamin Petersonecdae192010-01-04 00:43:01 +0000826
Antoine Pitrou5b7139a2010-01-02 21:12:58 +0000827- Issue #7462: Implement the stringlib fast search algorithm for the `rfind`,
828 `rindex`, `rsplit` and `rpartition` methods. Patch by Florent Xicluna.
829
Mark Dickinson1b34d252010-01-01 17:27:30 +0000830- Issue #5080: A number of functions and methods previously produced a
Georg Brandlba83f822010-03-14 09:50:54 +0000831 DeprecationWarning when passed a float argument where an integer was expected.
832 These functions and methods now raise TypeError instead. The majority of the
833 effects of this change are in the extension modules, but some core functions
834 and methods are affected: notably the 'chr', 'range' and 'xrange' builtins,
835 and many unicode/str methods.
Mark Dickinson1b34d252010-01-01 17:27:30 +0000836
Benjamin Peterson0f02d392009-12-30 19:34:10 +0000837- Issue #7604: Deleting an unset slotted attribute did not raise an
838 AttributeError.
839
Georg Brandlba83f822010-03-14 09:50:54 +0000840- Issue #7534: Fix handling of IEEE specials (infinities, nans, negative zero)
841 in ** operator. The behaviour now conforms to that described in C99 Annex F.
Mark Dickinson99d652e2009-12-30 12:12:23 +0000842
Georg Brandlba83f822010-03-14 09:50:54 +0000843- Issue #7579: The msvcrt module now has docstrings for all its functions.
Amaury Forgeot d'Arcc8a2ce72009-12-29 23:06:17 +0000844
Amaury Forgeot d'Arc8645a5c2009-12-29 22:03:38 +0000845- Issue #7413: Passing '\0' as the separator to datetime.datetime.isoformat()
846 used to drop the time part of the result.
847
Georg Brandlba83f822010-03-14 09:50:54 +0000848- Issue #1811: Improve accuracy and cross-platform consistency for true division
849 of integers: the result of a/b is now correctly rounded for ints a and b (at
850 least on IEEE 754 platforms), and in particular does not depend on the
851 internal representation of a long.
Mark Dickinson46572832009-12-27 14:55:57 +0000852
Georg Brandlba83f822010-03-14 09:50:54 +0000853- Issue #6108: ``unicode(exception)`` and ``str(exception)`` should return the
854 same message when only ``__str__()`` (and not ``__unicode__()``) is overridden
855 in the subclass.
Ezio Melottif84caf42009-12-24 22:25:17 +0000856
Georg Brandlba83f822010-03-14 09:50:54 +0000857- Issue #6834: Replace the implementation for the 'python' and 'pythonw'
Ronald Oussoren92919a62009-12-24 13:30:58 +0000858 executables on OSX.
859
Georg Brandlba83f822010-03-14 09:50:54 +0000860 These executables now work properly with the arch(1) command: ``arch -ppc
861 python`` will start a universal binary version of python in PPC mode (unlike
862 previous releases).
Ronald Oussoren92919a62009-12-24 13:30:58 +0000863
Georg Brandlba83f822010-03-14 09:50:54 +0000864- Issue #1680159: Unicode coercion during an 'in' operation no longer masks the
865 underlying error when the coercion fails for the left hand operand.
R. David Murray0a0a1a82009-12-14 16:28:26 +0000866
Benjamin Peterson4895af42009-12-13 16:36:53 +0000867- Issue #7491: Metaclass's __cmp__ method was ignored.

875
Georg Brandlba83f822010-03-14 09:50:54 +0000876- Issue #6963: Added "maxtasksperchild" argument to ``multiprocessing.Pool``,
877 allowing for a maximum number of tasks within the pool to be completed by the
878 worker before that worker is terminated, and a new one created to replace it.
Jesse Noller654ade32010-01-27 03:05:57 +0000879
Georg Brandlba83f822010-03-14 09:50:54 +0000880- Issue #7617: Make sure distutils.unixccompiler.UnixCCompiler recognizes gcc

Antoine Pitrou80157252010-01-08 19:20:17 +0000884- Issue #7092: Remove py3k warning when importing cPickle. 2to3 handles
Georg Brandlba83f822010-03-14 09:50:54 +0000885 renaming of `cPickle` to `pickle`. The warning was annoying since there's no
886 alternative to cPickle if you care about performance. Patch by Florent
Antoine Pitrou80157252010-01-08 19:20:17 +0000887 Xicluna.

Ezio Melotti569e61f2009-12-30 06:14:51 +0000906 Initial patch by Brian Curtin.
907
Georg Brandlba83f822010-03-14 09:50:54 +0000908- Distutils now correctly identifies the build architecture as "x86_64" when
909 building on OSX 10.6 without "-arch" flags.
Ronald Oussorenca8e7ec2009-12-24 14:50:35 +0000910

915 Distutils upload command to avoid an error when PyPI reads it. This occurs on
916 long passwords. Initial patch by JP St. Pierre.
Tarek Ziadé2421d562009-12-20 23:23:34 +0000917
Georg Brandlba83f822010-03-14 09:50:54 +0000918- Issue #7231: urllib2 cannot handle https with proxy requiring auth. Patch by

Benjamin Petersonddd392c2009-12-13 19:19:07 +0000921- Issue #7349: Make methods of file objects in the io module accept None as an
922 argument where file-like objects (ie StringIO and BytesIO) accept them to mean
923 the same as passing no argument.
924
Georg Brandlba83f822010-03-14 09:50:54 +0000925- Issue #7348: ``StringIO.StringIO.readline(-1)`` now acts as if it got no
926 argument like other file objects.

945 to ``PyLong_AsLongAndOverflow()``.
Mark Dickinsona36507c2010-01-30 10:08:33 +0000946
Georg Brandlba83f822010-03-14 09:50:54 +0000947- Issue #5080: The argument parsing functions ``PyArg_ParseTuple()``,
948 ``PyArg_ParseTupleAndKeywords()``, ``PyArg_VaParse()``,
949 ``PyArg_VaParseTupleAndKeywords()`` and ``PyArg_Parse()`` no longer accept
950 float arguments for integer format codes (other than 'L'): previously an
951 attempt to pass a float resulted in a DeprecationWarning; now it gives a
952 TypeError. For the 'L' format code (which previously had no warning) there is
953 now a DeprecationWarning.

Georg Brandlba83f822010-03-14 09:50:54 +0000997- Issue #7419: ``locale.setlocale()`` could crash the interpreter on Windows
998 when called with invalid values.
Amaury Forgeot d'Arcd7288712009-12-01 21:51:04 +0000999
Georg Brandlba83f822010-03-14 09:50:54 +00001000- Issue #3382: 'F' formatting for float and complex now convert the result to
1001 upper case. This only affects 'inf' and 'nan', since 'f' no longer converts
1002 to 'g' for large values.
Amaury Forgeot d'Arcd7288712009-12-01 21:51:04 +00001003
Georg Brandlba83f822010-03-14 09:50:54 +00001004- Remove switch from "%f" formatting to "%g" formatting for floats larger than
1005 1e50 in absolute value.
Mark Dickinson9dd5e162009-11-23 20:54:09 +00001006
Georg Brandlba83f822010-03-14 09:50:54 +00001007- Remove restrictions on precision when formatting floats. E.g., "%.120g" %
1008 1e-100 used to raise OverflowError, but now gives the requested 120
1009 significant digits instead.
Mark Dickinson18cfada2009-11-23 18:46:41 +00001010

1016 10.6.
Ronald Oussoren315cd0c2009-11-19 16:25:21 +00001017
Georg Brandlba83f822010-03-14 09:50:54 +00001018- Issue #7117: ``repr(x)`` for a float x returns a result based on the shortest
1019 decimal string that's guaranteed to round back to x under correct rounding
1020 (with round-half-to-even rounding mode). Previously it gave a string based on
1021 rounding x to 17 decimal digits. repr(x) for a complex number behaves
1022 similarly. On platforms where the correctly-rounded strtod and dtoa code is
1023 not supported (see below), repr is unchanged.
Mark Dickinsonb678de82009-11-19 18:41:49 +00001024
Georg Brandlba83f822010-03-14 09:50:54 +00001025- Issue #7117: On almost all platforms: float-to-string and string-to-float
1026 conversions within Python are now correctly rounded. Places these conversions
1027 occur include: str for floats and complex numbers; the float and complex
1028 constructors; old-style and new-style numeric formatting; serialization and
1029 deserialization of floats and complex numbers using marshal, pickle and json;
1030 parsing of float and imaginary literals in Python code; Decimal-to-float
1031 conversion.
Mark Dickinsonb678de82009-11-19 18:41:49 +00001032
Georg Brandlba83f822010-03-14 09:50:54 +00001033 The conversions use a Python-adapted version of David Gay's well-known dtoa.c,
1034 providing correctly-rounded strtod and dtoa C functions. This code is
1035 supported on Windows, and on Unix-like platforms using gcc, icc or suncc as
1036 the C compiler. There may be a small number of platforms on which correct
1037 operation of this code cannot be guaranteed, so the code is not used: notably,
1038 this applies to platforms where the C double format is not IEEE 754 binary64,
1039 and to platforms on x86 hardware where the x87 FPU is set to 64-bit precision
1040 and Python's configure script is unable to determine how to change the FPU
1041 precision. On these platforms conversions use the platform strtod and dtoa,
1042 as before.
Mark Dickinsonb678de82009-11-19 18:41:49 +00001043
Georg Brandlba83f822010-03-14 09:50:54 +00001044- Issue #7117: Backport round implementation from Python 3.x. ``round()`` now
1045 uses the correctly-rounded string <-> float conversions described above (when
1046 available), and so produces correctly rounded results that will display nicely
1047 under the float repr. There are two related small changes: (1) round now
1048 accepts any class with an ``__index__()`` method for its second argument (but
1049 no longer accepts floats for the second argument), and (2) an excessively
1050 large second integer argument (e.g., ``round(1.234, 10**100)``) no longer
1051 raises an exception.
Mark Dickinsonbd15a062009-11-18 19:33:35 +00001052
Philip Jenveyfab8be22009-11-17 02:42:26 +00001053- Issue #1757126: Fix the cyrillic-asian alias for the ptcp154 encoding.
1054

Georg Brandlba83f822010-03-14 09:50:54 +00001428- On windows, ``os.chdir()`` given unicode was not working if

1430 this code path is really executed because I cannot move to such directory on
1431 win2k)

1457 PyUnicode_DecodeUTF8() once, remember the result and output it in a second

Amaury Forgeot d'Arc05e34492008-09-10 22:04:45 +00002834- Issue #3743: In a few places, PY_FORMAT_SIZE_T was incorrectly used with
2835 PyString_FromFormat or PyErr_Format to display size_t values. The macro
2836 PY_FORMAT_SIZE_T is designed to select the correct format for the OS
2837 ``printf`` function, whereas PyString_FromFormat has an independent
2838 implementation and uses "%zd" on all platforms for size_t values.
2839 This makes a difference on win64, where ``printf`` needs "%Id" to display
2840 64bit values.

Antoine Pitrou0668c622008-08-26 22:42:08 +00002860 match Python 2.5 speed despite the __instancecheck__ / __subclasscheck__

2864 type object.

2935 warnings.catch_warnings() along with some API cleanup. Expanding the tests
2936 for catch_warnings() also led to an improvement in the raising of a
2937 DeprecationWarning related to warnings.warn_explicit().
2938

2964 without limit.
2965

Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00003003What's New in Python 2.6 beta 3?
3004================================
3005
Barry Warsaw07a4a382008-08-21 01:15:08 +00003006*Release date: 20-Aug-2008*
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00003007
3008Core and Builtins
3009-----------------
3010
Guido van Rossumf8402962008-08-20 15:01:50 +00003011- Issue #1878: Remove Py_TPFLAGS_HAVE_VERSION_TAG from
3012 Py_TPFLAGS_DEFAULT when not building the core. This means 3rd party
3013 extensions do not automatically benefit from the class attribute
3014 cache; they will have to explicitly add Py_TPFLAGS_HAVE_VERSION_TAG
3015 to their tp_flags field if they care. This is a backwards
3016 compatibility feature; in 3.0, all types will use the cache by
3017 default.
3018
Benjamin Petersonf647dc12008-08-20 01:27:30 +00003019- Keyword arguments can now follow starred arguments. (``f(a, *args,
3020 keyword=23)`` is now valid syntax.)
3021
Thomas Heller0ad5ae02008-08-19 19:25:04 +00003022- ctypes function pointers that are COM methods have a boolean True
3023 value again.
3024
Martin v. Löwisf91d46a2008-08-12 14:49:50 +00003025- Issue #3139: Make buffer-interface thread-safe wrt. PyArg_ParseTuple,
3026 by denying s# to parse objects that have a releasebuffer procedure,
3027 and introducing s*.
3028
Georg Brandl1e13ea92008-08-11 09:07:59 +00003029- Issue #3537: Fix an assertion failure when an empty but presized dict
3030 object was stored in the freelist.
3031
Mark Dickinsonb6467572008-08-04 21:30:09 +00003032- Issue #1481296: Make long(float('nan')) and int(float('nan')) raise
3033 ValueError consistently across platforms.
3034
Amaury Forgeot d'Arc39fd6722008-07-31 21:28:03 +00003035- Issue #3479: On platforms where sizeof(int) is smaller than sizeof(long)
3036 (64bit Unix, for example), unichr() would truncate its argument and return
3037 u'\x00' for unichr(2**32). Now it properly raises an OverflowError.
3038
Neal Norwitze7d8be82008-07-31 17:17:14 +00003039- Apply security patches from Apple.
3040
Amaury Forgeot d'Arc246daed2008-07-31 00:42:16 +00003041- Issue #2542: Now that issubclass() may call arbitrary code, ensure that
3042 PyErr_ExceptionMatches returns 0 when an exception occurs there.
3043
Antoine Pitrou92f82162008-07-25 22:22:08 +00003044- Issue #1819: function calls with several named parameters are now on
3045 average 35% faster (as measured by pybench).
3046
Amaury Forgeot d'Arce4921fe2008-07-21 22:00:38 +00003047- Issue #2378: An unexpected UnboundLocalError or NameError could appear when
3048 the python debugger steps into a class statement: the free variables (local
3049 variables defined in an outer scope) would be deleted from the outer scope.
3050
Gregory P. Smith0470bab2008-07-22 04:46:32 +00003051- Issue #2620: Overflow checking when allocating or reallocating memory
3052 was not always being done properly in some python types and extension
3053 modules. PyMem_MALLOC, PyMem_REALLOC, PyMem_NEW and PyMem_RESIZE have
3054 all been updated to perform better checks and places in the code that
3055 would previously leak memory on the error path when such an allocation
3056 failed have been fixed.
3057
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00003058Library
3059-------
3060
Hirokazu Yamamoto838c79f2008-08-20 13:14:07 +00003061- Issue #3612: Added some missing basic types in ctypes.wintypes.
3062
Benjamin Petersone977ad42008-08-20 01:42:01 +00003063- The methods ``is_in_tuple()``, ``is_vararg()``, and ``is_keywordarg()`` of
3064 symtable.Symbol have been deprecated for removal in 3.0 and the next release.
3065
Amaury Forgeot d'Arc351ffb82008-08-18 19:23:47 +00003066- Issue #2234: distutils failed for some versions of the cygwin compiler. The
3067 version reported by these tools does not necessarily follow the python
3068 version numbering scheme, so the module is less strict when parsing it.
3069
Nick Coghlanf70385a2008-08-18 12:42:46 +00003070- Issue #2235: Added Py3k warnings for types which will become unhashable
3071 under the stricter __hash__ inheritance rules in 3.0. Several types
3072 which did not meet the rules for hash invariants and were already
3073 unhashable in 3.0 have now been explicitly flagged as unhashable in
3074 2.6 as well (collections.Mapping, collections.Set, unittest.TestSuite,
3075 xml.dom.minidom.NamedNodeMap, numbers.Number, UserList.UserList)
3076
Brett Cannon88f801d2008-08-18 00:46:22 +00003077- Update __all__ for cookielib, csv, os, urllib2, and weakref to include things
3078 imported into the module but exposed as part of the module's API.

3081
Brett Cannon46225e72008-08-18 00:36:52 +00003082- Remove unneeded imports of 'sys' and 'warnings' from 'io'.

3085
Hirokazu Yamamoto41a81eb2008-08-17 13:10:46 +00003086- Issue #3575: Incremental decoder's decode function now takes bytearray
3087 by using 's*' instead of 't#'.
3088
Mark Dickinson3e4caeb2009-02-21 20:27:01 +00003089- Issue #2222: Fixed reference leak when occurred os.rename()
Hirokazu Yamamoto7f30a682008-08-17 09:46:56 +00003090 fails unicode conversion on 2nd parameter. (windows only)
3091
Facundo Batista94f243a2008-08-17 03:38:39 +00003092- Issue 2464. urllib2 now supports a malformation in the URL received
3093 in a redirect.
3094
Brett Cannonabe423e2008-08-16 21:47:07 +00003095- Silence the DeprecationWarning raised when importing mimetools in
Brett Cannon721b1452008-08-16 22:00:27 +00003096 BaseHTTPServer, cgi (and rfc822), httplib.
Brett Cannonabe423e2008-08-16 21:47:07 +00003097
Facundo Batistaeb90b782008-08-16 14:44:07 +00003098- Issue #2776: fixed small issue when handling an URL with double slash
3099 after a 302 response in the case of not going through a proxy.
3100
Antoine Pitroub90a8be2008-08-15 21:03:21 +00003101- Issue #2676: in the email package, content-type parsing was hanging on
3102 pathological input because of quadratic or exponential behaviour of a
3103 regular expression.
3104
Antoine Pitrou11ec65d2008-08-14 21:04:30 +00003105- Issue #3476: binary buffered reading through the new "io" library is now
3106 thread-safe.
3107
Brett Cannonbf3157b2008-08-14 05:00:03 +00003108- Silence the DeprecationWarning of rfc822 when it is imported by mimetools
3109 since mimetools itself is deprecated. Because modules are cached, all
3110 subsequent imports of rfc822 will not raise a visible DeprecationWarning.
3111
Antoine Pitrou9fcd4b32008-08-11 17:21:36 +00003112- Issue #3134: shutil referenced undefined WindowsError symbol.
3113
Robert Schuppenies14646332008-08-10 11:01:53 +00003114- Issue #1342811: Fix leak in Tkinter.Menu.delete. Commands associated to
3115 menu entries were not deleted.
3116
Brett Cannon83e81842008-08-09 23:30:55 +00003117- Copied the implementation of reduce() to _functools.reduce() to have a
3118 version that did not raise a DeprecationWarning under -3.
3119
Antoine Pitrou76b8bee2008-08-09 17:27:23 +00003120- Issue #3205: When iterating over a BZ2File fails allocating memory, raise
3121 a MemoryError rather than silently stop the iteration.
3122
Guido van Rossum59ce9012008-08-09 14:55:34 +00003123- Issue #3487: sre "bytecode" validator. Passing invalid "re-bytecode"
3124 to _sre.compile() will now be rejected. This should not affect anybody
3125 since the re.compile() function never generates invalid re-bytecode.
3126
Skip Montanaroa032bf42008-08-08 22:52:51 +00003127- Issue #3436: Make csv.DictReader's fieldnames attribute a property so that

Brett Cannon3aa2a492008-08-06 22:28:09 +00003131- Issue #2338: Create imp.reload() to help with transitioning to Python 3.0 as
3132 the reload() built-in has been removed.
3133
Brett Cannon7e30b672008-08-04 21:52:25 +00003134- Changed code in the following modules/packages to remove warnings raised
Brett Cannonc1b76e42008-08-09 23:06:16 +00003135 while running under the ``-3`` flag: aifc, asynchat, asyncore, bdb, bsddb,

Antoine Pitroude781a42008-08-09 12:43:23 +00003146 asking for a specific length. This problem only affected files opened
3147 using the new "io" module, not the built-in open() function.

3174 mode 0600 rather than 000 under Unix.
3175
Gregory P. Smitha36f8fe2008-08-04 00:13:29 +00003176- Issue #1857: subprocess.Popen.poll gained an additional _deadstate keyword

Mark Dickinson7103aa42008-07-15 19:08:33 +00003215- Issue #3008: the float type has a new instance method 'float.hex'
3216 and a new class method 'float.fromhex' to convert floating-point
3217 numbers to and from hexadecimal strings, respectively.
3218
Nick Coghlan6d6bd442008-07-15 15:40:22 +00003219- Issue #2235: __hash__ is once again inherited by default. To allow
3220 collections.Hashable to remain meaningful in the presence of the
3221 default hash implementation (object.__hash__), it is now possible
3222 to explicit block inheritance of hash by setting __hash__=None at
3223 the Python level, or tp_hash=PyObject_HashNotImplemented at the C
3224 level.
3225
Nick Coghlanb028f502008-07-13 14:52:36 +00003226- Issue #3221: Issue a RuntimeWarning instead of raising SystemError if
3227 the parent module cannot be found while performing an absolute import.
3228 This means that an incorrectly defined __package__ attribute will
3229 now only prevent relative imports in that module rather than causing
3230 all imports from that module to fail.
3231
Nick Coghlan14ff9942008-07-08 14:21:42 +00003232- Issue #2517: Allow unicode messages in Exceptions again by correctly

3243
Mark Dickinson1ec2fcd2008-06-20 14:53:43 +00003244- Issue #3004: Minor change to slice.indices(): the start and stop
3245 arguments are now treated identically, making the behaviour easier
3246 to describe and understand. For example, slice(None, -10,
3247 1).indices(9) now returns (0, 0, 1) instead of (0, -1, 1), and
3248 slice(None, 10, -1).indices(10) returns (9, 9, -1) instead of (9,
3249 10, -1).

3292 both unnecessary (HTTP allows text content to be sent in several forms) and
Andrew M. Kuchlingcc3f2b12008-07-10 14:43:31 +00003293 wrong because the actual transmitted size could differ from the

3770 not called by default for backwards-compatibility reasons. Setting
3771 ``warnings.showwarning()`` to an implementation that lacks support
3772 for the ``line`` argument will raise a DeprecationWarning.

Georg Brandl3ee81df2008-05-17 18:14:43 +00003835- Issue #2550: The approach used by client/server code for obtaining
3836 ports to listen on in network-oriented tests has been refined in an
3837 effort to facilitate running multiple instances of the entire
3838 regression test suite in parallel without issue.
3839 test_support.bind_port() has been fixed such that it will always
3840 return a unique port -- which wasn't always the case with the
3841 previous implementation, especially if socket options had been set
3842 that affected address reuse (i.e. SO_REUSEADDR, SO_REUSEPORT). The
3843 new implementation of bind_port() will actually raise an exception
3844 if it is passed an AF_INET/SOCK_STREAM socket with either the
3845 SO_REUSEADDR or SO_REUSEPORT socket option set. Furthermore, if
3846 available, bind_port() will set the SO_EXCLUSIVEADDRUSE option on
3847 the socket it's been passed. This currently only applies to
3848 Windows. This option prevents any other sockets from binding to the
3849 host/port we've bound to, thus removing the possibility of the
3850 'non-deterministic' behaviour, as Microsoft puts it, that occurs
3851 when a second SOCK_STREAM socket binds and accepts to a host/port
3852 that's already been bound by another socket. The optional preferred
3853 port parameter to bind_port() has been removed. Under no
3854 circumstances should tests be hard coding ports!
3855
3856 test_support.find_unused_port() has also been introduced, which will
3857 pass a temporary socket object to bind_port() in order to obtain an
3858 unused port. The temporary socket object is then closed and
3859 deleted, and the port is returned. This method should only be used
3860 for obtaining an unused port in order to pass to an external program
3861 (i.e. the -accept [port] argument to openssl's s_server mode) or as
3862 a parameter to a server-oriented class that doesn't give you direct
3863 access to the underlying socket used.
3864
3865 Finally, test_support.HOST has been introduced, which should be used
3866 for the host argument of any relevant socket calls (i.e. bind and
3867 connect).
Trent Nelsone41b0062008-04-08 23:47:30 +00003868
3869 The following tests were updated to following the new conventions:
Georg Brandl3ee81df2008-05-17 18:14:43 +00003870 test_socket, test_smtplib, test_asyncore, test_ssl, test_httplib,
Trent Nelsone41b0062008-04-08 23:47:30 +00003871 test_poplib, test_ftplib, test_telnetlib, test_socketserver,
3872 test_asynchat and test_socket_ssl.
3873
Georg Brandl3ee81df2008-05-17 18:14:43 +00003874 It is now possible for multiple instances of the regression test
3875 suite to run in parallel without issue.

Georg Brandl3ee81df2008-05-17 18:14:43 +00004041- Issue #1202: zlib.crc32 and zlib.adler32 no longer return different
4042 values on 32-bit vs. 64-bit python interpreters. Both were correct,
4043 but they now both return a signed integer object for consistency.

4142-----------------
4143
Fred Drakea8ee94b2008-03-01 02:45:07 +00004144- Issue #2051: pyc and pyo files are no longer created with permission
Barry Warsaw52973612008-03-01 02:23:38 +00004145 644. The mode is now inherited from the py file.

Georg Brandlad61bc82008-02-23 15:11:18 +00004147- Issue #2067: file.__exit__() now calls subclasses' close() method.
4148
4149- Patch #1759: Backport of PEP 3129 class decorators.
Christian Heimes5224d282008-02-23 15:01:05 +00004150
Vinay Sajipb7edfc42008-04-02 21:10:23 +00004151- Issue #1881: An internal parser limit has been increased. Also see
Facundo Batistafc2d0102008-02-23 12:01:13 +00004152 issue 215555 for a discussion.
4153
Eric Smitha73fbe72008-02-23 03:09:44 +00004154- Added the future_builtins module, which contains hex() and oct().
4155 These are the PEP 3127 version of these functions, designed to be
4156 compatible with the hex() and oct() builtins from Python 3.0. They
4157 differ slightly in their output formats from the existing, unchanged
4158 Python 2.6 builtins. The expected usage of the future_builtins
4159 module is:
4160 from future_builtins import hex, oct
4161
Eric Smith7ef40bf2008-02-20 23:34:22 +00004162- Issue #1600: Modifed PyOS_ascii_formatd to use at most 2 digit
4163 exponents for exponents with absolute value < 100. Follows C99
4164 standard. This is a change on Windows, which would use 3 digits.
4165 Also, added 'n' to the formats that PyOS_ascii_formatd understands,
4166 so that any alterations it does to the resulting string will be
4167 available in stringlib/formatter.h (for float.__format__).
4168
Eric Smith5a3c1352008-02-19 13:21:56 +00004169- Implemented PEP 3101, Advanced String Formatting. This adds a new
4170 builtin format(); a format() method for str and unicode; a
4171 __format__() method to object, str, unicode, int, long, float, and
4172 datetime; the class string.Formatter; and the C API
4173 PyObject_Format().
4174
Georg Brandl3ee81df2008-05-17 18:14:43 +00004175- Fixed several potential crashes, all caused by specially crafted
4176 __del__ methods exploiting objects in temporarily inconsistent
4177 state.
Amaury Forgeot d'Arc632fad32008-02-16 20:55:24 +00004178
Vinay Sajipb7edfc42008-04-02 21:10:23 +00004179- Issue #2115: Important speedup in setting __slot__ attributes. Also
Georg Brandl3ee81df2008-05-17 18:14:43 +00004180 prevent a possible crash: an Abstract Base Class would try to access
4181 a slot on a registered virtual subclass.
Amaury Forgeot d'Arc60d6c7f2008-02-15 21:22:45 +00004182
Georg Brandl3ee81df2008-05-17 18:14:43 +00004183- Fixed repr() and str() of complex numbers with infinity or nan as
4184 real or imaginary part.
Christian Heimes2f0da532008-02-15 06:57:08 +00004185
Georg Brandl3ee81df2008-05-17 18:14:43 +00004186- Clear all free lists during a gc.collect() of the highest generation
4187 in order to allow pymalloc to free more arenas. Python may give back
4188 memory to the OS earlier.
Christian Heimes3b718a72008-02-14 12:47:33 +00004189
Georg Brandl3ee81df2008-05-17 18:14:43 +00004190- Issue #2045: Fix an infinite recursion triggered when printing a
4191 subclass of collections.defaultdict, if its default_factory is set
4192 to a bound method.
Amaury Forgeot d'Arcb01aa432008-02-08 00:56:02 +00004193
Christian Heimesf75dbef2008-02-08 00:11:31 +00004194- Fixed a minor memory leak in dictobject.c. The content of the free
4195 list was not freed on interpreter shutdown.
4196
Georg Brandl21e99f42010-03-07 15:23:59 +00004197- Limit free list of method and built-in function objects to 256
Georg Brandl3ee81df2008-05-17 18:14:43 +00004198 entries each.
Christian Heimes6075a822008-02-06 12:44:34 +00004199
Georg Brandl3ee81df2008-05-17 18:14:43 +00004200- Patch #1953: Added ``sys._compact_freelists()`` and the C API
4201 functions ``PyInt_CompactFreeList`` and ``PyFloat_CompactFreeList``
Christian Heimes422051a2008-02-04 18:00:12 +00004202 to compact the internal free lists of pre-allocted ints and floats.
4203
Georg Brandl3ee81df2008-05-17 18:14:43 +00004204- Issue #1983: Fixed return type of fork(), fork1() and forkpty()
4205 calls. Python expected the return type int but the fork familie
4206 returns pi_t.
Christian Heimes951cc0f2008-01-31 23:08:23 +00004207
Georg Brandl3ee81df2008-05-17 18:14:43 +00004208- Issue #1678380: Fix a bug that identifies 0j and -0j when they
4209 appear in the same code unit.
Mark Dickinson105be772008-01-31 22:17:37 +00004210
Georg Brandl3ee81df2008-05-17 18:14:43 +00004211- Issue #2025: Add tuple.count() and tuple.index() methods to comply
4212 with the collections.Sequence API.
Raymond Hettinger5b07ebc2008-02-07 00:54:20 +00004213

Georg Brandl3ee81df2008-05-17 18:14:43 +00004217- Added ``PyType_ClearCache()`` and ``sys._clear_type_cache`` to clear
4218 the internal lookup cache for ref leak tests.
Christian Heimes908caac2008-01-27 23:34:59 +00004219
Georg Brandl3ee81df2008-05-17 18:14:43 +00004220- Patch #1473257: generator objects gain a gi_code attribute. This is
4221 the same object as the func_code attribute of the function that
4222 produced the generator.
Georg Brandl0cdf9a32008-01-26 14:14:20 +00004223
Georg Brandl3ee81df2008-05-17 18:14:43 +00004224- Issue #1920: "while 0" statements were completely removed by the
4225 compiler, even in the presence of an "else" clause, which is
4226 supposed to be run when the condition is false. Now the compiler
4227 correctly emits bytecode for the "else" suite.
Amaury Forgeot d'Arc31eaafe2008-01-24 22:59:25 +00004228
Guido van Rossumeead05f2008-01-24 18:21:02 +00004229- A few crashers fixed: weakref_in_del.py (issue #1377858);
4230 loosing_dict_ref.py (issue #1303614, test67.py);
4231 borrowed_ref_[34].py (not in tracker).
4232
Vinay Sajipd7cf32e2008-01-24 12:43:33 +00004233- Issue #1069410: The "can't load dll" message box on Windows is
Christian Heimesb2302ba2008-01-23 17:15:06 +00004234 suppressed while an extension is loaded by calling SetErrorMode in
4235 dynload_win.c. The error is still reported properly.
4236
Georg Brandl3ee81df2008-05-17 18:14:43 +00004237- Issue #1915: Python compiles with --enable-unicode=no again. However
Christian Heimes082c9b02008-01-23 14:20:50 +00004238 several extension methods and modules do not work without unicode
4239 support.
4240
Georg Brandl26543b12008-01-21 18:36:51 +00004241- Issue #1882: when compiling code from a string, encoding cookies in the
4242 second line of code were not always recognized correctly.
4243
Georg Brandl14404b62008-01-19 19:27:05 +00004244- Issue #1679: "0x" was taken as a valid integer literal.
4245
Georg Brandl6caad7d2008-01-26 14:19:22 +00004246- Issue #1865: ``bytes`` as an alias for ``str`` and b"" as an alias "" were
Christian Heimes288e89a2008-01-18 18:24:07 +00004247 added.
4248
Christian Heimesc94e2b52008-01-14 04:13:37 +00004249- sys.float_info / PyFloat_GetInfo: The floating point information
4250 object was converted from a dict to a specialized structseq object.
4251
Georg Brandl3ee81df2008-05-17 18:14:43 +00004252- Patch #1816: Added sys.flags structseq. It exposes the status of
4253 most command line arguments and PYTHON* environment variables.
Christian Heimesf31b69f2008-01-14 03:42:48 +00004254
Georg Brandl3ee81df2008-05-17 18:14:43 +00004255- Objects/structseq.c: Implemented new structseq representation. The
4256 patch makes structseqs (e.g. the return value of os.stat) more
4257 readable.
Christian Heimes9c201962008-01-14 03:33:52 +00004258
Georg Brandl3ee81df2008-05-17 18:14:43 +00004259- Patch #1700288: added a type attribute cache that caches method
4260 accesses, resulting in speedups in heavily object-oriented code.

4268 envvar and sys.dont_write_bytecode attribute. All these can be set
4269 to forbid Python to attempt to write compiled bytecode files.
Georg Brandl2da0fce2008-01-07 17:09:35 +00004270
Georg Brandl3ee81df2008-05-17 18:14:43 +00004271- Improve some exception messages when Windows fails to load an
4272 extension module. Now we get for example '%1 is not a valid Win32
4273 application' instead of 'error code 193'.
Amaury Forgeot d'Arce0b76952008-01-04 02:04:15 +00004274

Georg Brandl3ee81df2008-05-17 18:14:43 +00004281 and INF. float("nan"), float("inf") and float("-inf") now work on
4282 every platform with IEEE 754 semantics.

Georg Brandl3ee81df2008-05-17 18:14:43 +00004284- Compiler now generates simpler and faster code for dictionary
4285 literals. The oparg for BUILD_MAP now indicates an estimated
4286 dictionary size. There is a new opcode, STORE_MAP, for adding
4287 entries to the dictionary.

4299
Nick Coghlanef01d822007-12-03 12:55:17 +00004300- PEP 366: Allow explicit relative imports when executing modules

4305 running, and if the deallocation of its frames somehow calls the
4306 PyGILState_Ensure() / PyGILState_Release() functions.
Amaury Forgeot d'Arcbe49a902007-11-30 20:37:22 +00004307

Georg Brandl3ee81df2008-05-17 18:14:43 +00004316- Patch #1739468: Directories and zipfiles containing a __main__.py
4317 file can now be directly executed by passing their name to the
4318 interpreter. The directory/zipfile is automatically inserted as the
4319 first entry in sys.path.
Nick Coghlan327a39b2007-11-18 11:56:28 +00004320
Georg Brandl3ee81df2008-05-17 18:14:43 +00004321- Issue #1265: Fix a problem with sys.settrace, if the tracing
4322 function uses a generator expression when at the same time the
4323 executed code is closing a paused generator.
Amaury Forgeot d'Arc0d75f092007-11-13 21:54:28 +00004324
Raymond Hettinger1760c8a2007-11-08 02:52:43 +00004325- sets and frozensets now have an isdisjoint() method.

4330
Georg Brandl21e99f42010-03-07 15:23:59 +00004331- The enumerate() built-in function is no longer bounded to sequences
Georg Brandl3ee81df2008-05-17 18:14:43 +00004332 smaller than LONG_MAX. Formerly, it raised an OverflowError. Now,
4333 automatically shifts from ints to longs.
Raymond Hettinger8f669372007-10-03 21:18:11 +00004334
Georg Brandl3ee81df2008-05-17 18:14:43 +00004335- Issue #1686386: Tuple's tp_repr did not take into account the
4336 possibility of having a self-referential tuple, which is possible
4337 from C code. Nor did object's tp_str consider that a type's tp_str
4338 could do something that could lead to an inifinite recursion.
4339 Py_ReprEnter() and Py_EnterRecursiveCall(), respectively, fixed the
4340 issues.
Brett Cannon0b14f242007-09-30 19:45:10 +00004341
Georg Brandl3ee81df2008-05-17 18:14:43 +00004342- Issue #1164: It was possible to trigger deadlock when using the
4343 'print' statement to write to a file since the GIL was not released
4344 as needed. Now PyObject_Print() does the right thing along with
4345 various tp_print implementations of the built-in types and those in
4346 the collections module.
Brett Cannon01531592007-09-17 03:28:34 +00004347
Georg Brandl3ee81df2008-05-17 18:14:43 +00004348- Issue #1147: Exceptions were directly allowing string exceptions in
4349 their throw() method even though string exceptions no longer
4350 allowed.
Brett Cannon4c20bc42007-09-11 21:02:28 +00004351
Georg Brandl3ee81df2008-05-17 18:14:43 +00004352- Issue #1096: Prevent a segfault from getting the repr of a very
4353 deeply nested list by using the recursion counter.
Brett Cannona0c05512007-09-10 21:38:27 +00004354
Brett Cannon1e534b52007-09-07 04:18:30 +00004355- Issue #1202533: Fix infinite recursion calls triggered by calls to
Georg Brandl3ee81df2008-05-17 18:14:43 +00004356 PyObject_Call() never calling back out to Python code to trigger
4357 recursion depth updates/checks. Required the creation of a static
4358 RuntimeError instance in case normalizing an exception put the
4359 recursion check value past its limit. Fixes crashers
4360 infinite_rec_(1|2|4|5).py.
Brett Cannon1e534b52007-09-07 04:18:30 +00004361
Georg Brandl3ee81df2008-05-17 18:14:43 +00004362- Patch #1031213: Decode source line in SyntaxErrors back to its

Neal Norwitz0ac60192007-05-27 04:08:54 +00004375- Add new attribute names for function objects. All the func_* become
Georg Brandl3ee81df2008-05-17 18:14:43 +00004376 __*__ attributes. (Some already existed, e.g., __doc__ and
4377 __name__.)
Neal Norwitz0ac60192007-05-27 04:08:54 +00004378
Neal Norwitz8b2bfbc2007-05-23 06:35:32 +00004379- Add -3 option to the interpreter to warn about features that are
4380 deprecated and will be changed/removed in Python 3.0.
4381
Georg Brandl2134e752007-05-21 20:34:16 +00004382- Patch #1686487: you can now pass any mapping after '**' in function
4383 calls.
4384
Collin Winter62903052007-05-18 23:11:24 +00004385- except clauses may now be spelled either "except E, target:" or
Georg Brandl3ee81df2008-05-17 18:14:43 +00004386 "except E as target:". This is to provide forwards compatibility
4387 with Python 3.0.
Collin Winter62903052007-05-18 23:11:24 +00004388
Brett Cannon229cee22007-05-05 01:34:02 +00004389- Deprecate BaseException.message as per PEP 352.
4390
Georg Brandl3ee81df2008-05-17 18:14:43 +00004391- Issue #1303614: don't expose object's __dict__ when the dict is
Georg Brandl21e99f42010-03-07 15:23:59 +00004392 inherited from a built-in base.
Armin Rigo9790a272007-05-02 19:23:31 +00004393
Vinay Sajip8549ce32007-05-06 17:53:37 +00004394- When __slots__ are set to a unicode string, make it work the same as
Neal Norwitzcbd9ee62007-04-14 05:25:50 +00004395 setting a plain string, ie don't expand to single letter identifiers.
4396
Raymond Hettinger13936692007-04-11 18:40:58 +00004397- Request #1191699: Slices can now be pickled.
4398
Raymond Hettinger4db5fe92007-04-12 04:10:00 +00004399- Request #1193128: str.translate() now allows a None argument for
4400 translations that only remove characters without re-mapping the
4401 remaining characters.
4402
Georg Brandl5cb76c12007-03-21 09:00:39 +00004403- Patch #1682205: a TypeError while unpacking an iterable is no longer
4404 masked by a generic one with the message "unpack non-sequence".
4405
Neal Norwitzaa754b72007-03-21 06:39:48 +00004406- Remove unused file Python/fmod.c.
4407
Guido van Rossum143b5642007-03-23 04:58:42 +00004408- Bug #1683368: The object.__init__() and object.__new__() methods are
4409 now stricter in rejecting excess arguments. The only time when
4410 either allows excess arguments is when it is not overridden and the
4411 other one is. For backwards compatibility, when both are
4412 overridden, it is a deprecation warning (for now; maybe a Py3k
Guido van Rossum234b1ff2007-03-23 19:39:01 +00004413 warning later). Also, type.__init__() insists on the same signature
4414 as supported by type.__new__().
Guido van Rossum143b5642007-03-23 04:58:42 +00004415
Georg Brandl3ee81df2008-05-17 18:14:43 +00004416- Patch #1675423: PyComplex_AsCComplex() now tries to convert an
4417 object to complex using its __complex__() method before falling back
4418 to the __float__() method. Therefore, the functions in the cmath
4419 module now can operate on objects that define a __complex__()
4420 method.
Georg Brandl2b869942007-03-17 16:08:45 +00004421
Georg Brandl3ee81df2008-05-17 18:14:43 +00004422- Patch #1623563: allow __class__ assignment for classes with
4423 __slots__. The old and the new class are still required to have the
4424 same slot names.
Žiga Seilnacht6f2d09c2007-03-16 11:59:38 +00004425
Georg Brandl3ee81df2008-05-17 18:14:43 +00004426- Patch #1642547: Fix an error/crash when encountering syntax errors

4430 ``object.__reduce_ex__()`` is called with an object that is faking
4431 its type.
Žiga Seilnacht20f43d32007-03-15 11:44:55 +00004432
Georg Brandl3ee81df2008-05-17 18:14:43 +00004433- Patch #1680015: Don't modify __slots__ tuple if it contains an

Georg Brandl5240d742007-03-13 20:46:32 +00004436- Patch #1444529: the builtin compile() now accepts keyword arguments.
4437
Georg Brandl7b9c5552007-03-12 14:30:05 +00004438- Bug #1678647: write a newline after printing an exception in any
4439 case, even when converting the value to a string failed.
4440
Georg Brandl871f1bc2007-03-12 13:17:36 +00004441- The dir() function has been extended to call the __dir__() method on
Georg Brandl3ee81df2008-05-17 18:14:43 +00004442 its argument, if it exists. If not, it will work like before. This
4443 allows customizing the output of dir() in the presence of a
4444 __getattr__().
Georg Brandl871f1bc2007-03-12 13:17:36 +00004445
Collin Winter276887b2007-03-12 16:11:39 +00004446- Patch #922167: Python no longer segfaults when faced with infinitely
4447 self-recursive reload() calls (as reported by bug #742342).
4448
Georg Brandl3ee81df2008-05-17 18:14:43 +00004449- Patch #1675981: remove unreachable code from ``type.__new__()``
4450 method.

Georg Brandl3ee81df2008-05-17 18:14:43 +00004452- Patch #1491866: change the complex() constructor to allow
4453 parthensized forms. This means complex(repr(x)) now works instead of
4454 raising a ValueError.
Collin Wintere38051d2007-03-09 20:33:07 +00004455
Georg Brandlaa2321b2007-03-07 00:40:28 +00004456- Patch #703779: unset __file__ in __main__ after running a file. This
Georg Brandl3ee81df2008-05-17 18:14:43 +00004457 makes the filenames the warning module prints much more sensible
4458 when a PYTHONSTARTUP file is used.
Georg Brandlaa2321b2007-03-07 00:40:28 +00004459
Georg Brandl49aafc92007-03-07 00:34:46 +00004460- Variant of patch #697613: don't exit the interpreter on a SystemExit
4461 exception if the -i command line option or PYTHONINSPECT environment
Georg Brandl3ee81df2008-05-17 18:14:43 +00004462 variable is given, but break into the interactive interpreter just
4463 like on other exceptions or normal program exit.

Georg Brandl098cd692007-03-06 12:17:50 +00004470
Georg Brandl0fca97a2007-03-05 22:28:08 +00004471- Patch #1674228: when assigning a slice (old-style), check for the
4472 sq_ass_slice instead of the sq_slice slot.
4473
Georg Brandl3ee81df2008-05-17 18:14:43 +00004474- When printing an unraisable error, don't print exceptions. before
4475 the name. This duplicates the behavior whening normally printing
4476 exceptions.
Neal Norwitz88516a62007-02-26 22:41:45 +00004477

5042
Georg Brandl92a6bae2007-03-13 17:43:32 +00005043- Patch #1603688: ConfigParser.SafeConfigParser now checks values that
Georg Brandl3ee81df2008-05-17 18:14:43 +00005044 are set for invalid interpolation sequences that would lead to
5045 errors on reading back those values.

5101 TestCase and TestSuite subclasses (not instances) are no longer
5102 accepted in TestSuite.addTest(). This should cause no
5103 incompatibility since it never made sense with ordinary subclasses
5104 -- the failure just occurred later, with a more cumbersome
5105 exception.

Gregory P. Smithbde4ae42008-01-17 08:35:49 +00005392 that the SMTP.starttls() caller no longer needs to call ehlo()

Georg Brandl3ee81df2008-05-17 18:14:43 +00005394 does not claim to support starttls. Adds the
5395 SMTP.ehlo_or_helo_if_needed() method. Patch contributed by Bill

Gregory P. Smithec10a4a2007-11-05 02:32:26 +00005493- pybsddb.sf.net Bug #477182: Load the database flags at database open
Georg Brandl3ee81df2008-05-17 18:14:43 +00005494 time so that opening a database previously created with the DB_DUP
5495 or DB_DUPSORT flag set will keep the proper behavior on subsequent
5496 opens. Specifically: dictionary assignment to a DB object will
5497 replace all values for a given key when the database allows
5498 duplicate values. DB users should use DB.put(k, v) when they want
5499 to store duplicates; not DB[k] = v.

5508 behavior of quoting dots if they are the second character of any

Raymond Hettingerdc1d1ba2007-11-07 02:45:46 +00005778- Add a FAST_LOOPS build option that speeds-up looping by trading away
Georg Brandl3ee81df2008-05-17 18:14:43 +00005779 periodic threadstate and signal checking in tight loops. By
5780 default, this option is turned-off. It should only be enabled in
5781 debugged, performance critical applications.

Christian Heimes5b970ad2008-02-06 13:33:44 +00005838
Georg Brandl3ee81df2008-05-17 18:14:43 +00005839- ``PySet_Add()`` can now modify a newly created frozenset. Similarly
5840 to ``PyTuple_SetItem``, it can be used to populate a brand new

5855 of w# format code incorrectly truncated the length to an int, even
5856 when PY_SSIZE_T_CLEAN is set. The str.decode method used to return
5857 incorrect results with huge strings.

5885 imports under some conditions.
Christian Heimes000a0742008-01-03 22:16:32 +00005886
Georg Brandl3ee81df2008-05-17 18:14:43 +00005887- Added case insensitive comparison methods ``PyOS_stricmp(char*,
5888 char*)`` and ``PyOS_strnicmp(char*, char*, Py_ssize_t)``.
Christian Heimes000a0742008-01-03 22:16:32 +00005889
