82 processing: any non-float non-integer argument is now converted to

136
Mark Dickinson4f96f5f2010-05-04 14:25:50 +0000137- Issue #8567: Fix precedence of signals in Decimal module: when a
138 Decimal operation raises multiple signals and more than one of those
139 signals is trapped, the specification determines the order in which
140 the signals should be handled. In many cases this order wasn't
141 being followed, leading to the wrong Python exception being raised.

172 suites, the IGNORE_EXCEPTION_DETAIL directive now also ignores the module
Nick Coghlan54677da2010-04-28 14:34:30 +0000173 location of the raised exception. Based on initial patch by Lennart
174 Regebro.

189 event loop started running. This also fixes the occasional freezes
190 witnessed in test_httpservers.
191
Antoine Pitroufc69af12010-04-24 20:04:58 +0000192- Issue #5103: SSL handshake would ignore the socket timeout and block

Eric Smithd44b2fc2010-04-02 12:30:56 +0000329- Issue #7994: Issue a PendingDeprecationWarning if object.__format__
330 is called with a non-empty format string. This is an effort to
331 future-proof user code. If a derived class does not currently
332 implement __format__ but later adds its own __format__, it would
333 most likely break user code that had supplied a format string. This
334 will be changed to a DeprecationWaring in Python 3.3 and it will be
335 an error in Python 3.4.

Mark Dickinson8a950712010-04-03 15:47:46 +0000368- Issue #8257: The Decimal construct now accepts a float instance
369 directly, converting that float to a Decimal of equal value:
370
371 >>> Decimal(1.1)

375
Raymond Hettingera551f312010-04-04 18:34:45 +0000376- the functools module now has a total_ordering() class decorator
Georg Brandl4fabac52010-04-14 08:53:38 +0000377 to simplify the specification of rich comparisons.

Mark Dickinsone096e822010-04-02 10:17:07 +0000385- Issue #7279: Comparisons involving a Decimal signaling NaN now
386 signal InvalidOperation instead of returning False. (Comparisons
Mark Dickinsonf3eeca12010-04-02 10:35:12 +0000387 involving a quiet NaN are unchanged.) Also, Decimal quiet NaNs
388 are now hashable; Decimal signaling NaNs remain unhashable.

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

Mark Dickinson4846a8e2010-04-03 14:05:10 +0000510- Issue #8300: When passing a non-integer argument to struct.pack with any
511 integer format code, struct.pack first attempts to convert the non-integer
512 using its __index__ method. If that method is non-existent or raises
513 TypeError it goes on to try the __int__ method, as described below.
514
Georg Brandlba83f822010-03-14 09:50:54 +0000515- Issue #1530559: When passing a non-integer argument to struct.pack with *any*
516 integer format code (one of 'bBhHiIlLqQ'), struct.pack attempts to use the
517 argument's __int__ method to convert to an integer before packing. It also
518 produces a DeprecationWarning in this case. (In Python 2.6, the behaviour
519 was inconsistent: __int__ was used for some integer codes but not for others,
520 and the set of integer codes for which it was used differed between native
521 packing and standard packing.)

Georg Brandlba83f822010-03-14 09:50:54 +0000825- Issue #7610: Reworked implementation of the internal ``zipfile.ZipExtFile``
826 class used to represent files stored inside an archive. The new
827 implementation is significantly faster and can be wrapped in a
828 ``io.BufferedReader`` object for more speedups. It also solves an issue
829 where interleaved calls to ``read()`` and ``readline()`` give wrong results.

917Core and Builtins
918-----------------
919
Georg Brandlba83f822010-03-14 09:50:54 +0000920- The ``__complex__()`` method is now looked up on the class of instances to
921 make it consistent with other special methods.

924 `rindex`, `rsplit` and `rpartition` methods. Patch by Florent Xicluna.
925
Mark Dickinson1b34d252010-01-01 17:27:30 +0000926- Issue #5080: A number of functions and methods previously produced a
Georg Brandlba83f822010-03-14 09:50:54 +0000927 DeprecationWarning when passed a float argument where an integer was expected.
928 These functions and methods now raise TypeError instead. The majority of the
929 effects of this change are in the extension modules, but some core functions
930 and methods are affected: notably the 'chr', 'range' and 'xrange' builtins,
931 and many unicode/str methods.

946 least on IEEE 754 platforms), and in particular does not depend on the
947 internal representation of a long.

955
Georg Brandlba83f822010-03-14 09:50:54 +0000956 These executables now work properly with the arch(1) command: ``arch -ppc

Georg Brandlba83f822010-03-14 09:50:54 +00001093- Issue #7419: ``locale.setlocale()`` could crash the interpreter on Windows
1094 when called with invalid values.

Georg Brandlba83f822010-03-14 09:50:54 +00001096- Issue #3382: 'F' formatting for float and complex now convert the result to
1097 upper case. This only affects 'inf' and 'nan', since 'f' no longer converts
1098 to 'g' for large values.
Amaury Forgeot d'Arcd7288712009-12-01 21:51:04 +00001099
Georg Brandlba83f822010-03-14 09:50:54 +00001100- Remove switch from "%f" formatting to "%g" formatting for floats larger than
1101 1e50 in absolute value.
Mark Dickinson9dd5e162009-11-23 20:54:09 +00001102
Georg Brandlba83f822010-03-14 09:50:54 +00001103- Remove restrictions on precision when formatting floats. E.g., "%.120g" %
1104 1e-100 used to raise OverflowError, but now gives the requested 120
1105 significant digits instead.

1112 10.6.
Ronald Oussoren315cd0c2009-11-19 16:25:21 +00001113
Georg Brandlba83f822010-03-14 09:50:54 +00001114- Issue #7117: ``repr(x)`` for a float x returns a result based on the shortest
1115 decimal string that's guaranteed to round back to x under correct rounding
1116 (with round-half-to-even rounding mode). Previously it gave a string based on
1117 rounding x to 17 decimal digits. repr(x) for a complex number behaves
1118 similarly. On platforms where the correctly-rounded strtod and dtoa code is
1119 not supported (see below), repr is unchanged.
Mark Dickinsonb678de82009-11-19 18:41:49 +00001120
Georg Brandlba83f822010-03-14 09:50:54 +00001121- Issue #7117: On almost all platforms: float-to-string and string-to-float
1122 conversions within Python are now correctly rounded. Places these conversions
1123 occur include: str for floats and complex numbers; the float and complex
1124 constructors; old-style and new-style numeric formatting; serialization and
1125 deserialization of floats and complex numbers using marshal, pickle and json;
1126 parsing of float and imaginary literals in Python code; Decimal-to-float
1127 conversion.
Mark Dickinsonb678de82009-11-19 18:41:49 +00001128
Georg Brandlba83f822010-03-14 09:50:54 +00001129 The conversions use a Python-adapted version of David Gay's well-known dtoa.c,
1130 providing correctly-rounded strtod and dtoa C functions. This code is
1131 supported on Windows, and on Unix-like platforms using gcc, icc or suncc as
1132 the C compiler. There may be a small number of platforms on which correct
1133 operation of this code cannot be guaranteed, so the code is not used: notably,
1134 this applies to platforms where the C double format is not IEEE 754 binary64,
1135 and to platforms on x86 hardware where the x87 FPU is set to 64-bit precision
1136 and Python's configure script is unable to determine how to change the FPU
1137 precision. On these platforms conversions use the platform strtod and dtoa,
1138 as before.
Mark Dickinsonb678de82009-11-19 18:41:49 +00001139
Georg Brandlba83f822010-03-14 09:50:54 +00001140- Issue #7117: Backport round implementation from Python 3.x. ``round()`` now
1141 uses the correctly-rounded string <-> float conversions described above (when
1142 available), and so produces correctly rounded results that will display nicely
1143 under the float repr. There are two related small changes: (1) round now
1144 accepts any class with an ``__index__()`` method for its second argument (but
1145 no longer accepts floats for the second argument), and (2) an excessively
1146 large second integer argument (e.g., ``round(1.234, 10**100)``) no longer
1147 raises an exception.

1150
Georg Brandlba83f822010-03-14 09:50:54 +00001151- Fix several issues with ``compile()``. The input can now contain Windows and

1183 The tables for code points representing numeric values, white spaces or line
1184 breaks are now generated from the official Unicode Character Database files,
1185 and include information from the Unihan.txt file.

Georg Brandlba83f822010-03-14 09:50:54 +00001294- Issue #5920: For ``float.__format__()``, change the behavior with the empty
1295 presentation type (that is, not one of 'e', 'f', 'g', or 'n') to be like 'g'
1296 but with at least one decimal point and with a default precision
1297 of 12. Previously, the behavior the same but with a default precision of 6.
1298 This more closely matches ``str()``, and reduces surprises when adding
1299 alignment flags to the empty presentation type. This also affects the new
1300 complex.__format__ in the same way.

2927
Martin v. Löwis9fa5a282008-09-11 06:53:30 +00002928- Issue #3642: Suppress warning in obmalloc when size_t is larger than uint.
2929
Amaury Forgeot d'Arc05e34492008-09-10 22:04:45 +00002930- Issue #3743: In a few places, PY_FORMAT_SIZE_T was incorrectly used with
2931 PyString_FromFormat or PyErr_Format to display size_t values. The macro
2932 PY_FORMAT_SIZE_T is designed to select the correct format for the OS
2933 ``printf`` function, whereas PyString_FromFormat has an independent
2934 implementation and uses "%zd" on all platforms for size_t values.
2935 This makes a difference on win64, where ``printf`` needs "%Id" to display
2936 64bit values.
2937
Benjamin Peterson97179b02008-09-09 20:55:01 +00002938- Issue #3634: _weakref.ref(Exception).__init__() gave invalid return value on
2939 error.
2940
Amaury Forgeot d'Arcd3ffb892008-09-09 07:24:30 +00002941- Issue #3777: long() applied to a float object now always return a long
2942 object; previously an int would be returned for small values. the __long__
2943 method is allowed to return either an int or a long, but the behaviour of
2944 float objects should not change to respect backward compatibility.
2945
Amaury Forgeot d'Arc3571fbf2008-09-01 19:52:00 +00002946- Issue #3751: str.rpartition would perform a left-partition when called with
2947 a unicode argument.
2948
Benjamin Peterson17f03ca2008-09-01 14:18:30 +00002949- Issue #3683: Fix compilation when --without-threads is given.
2950
Antoine Pitroud4ae97b2008-08-29 18:39:48 +00002951- Issue #3668: Fix a memory leak with the "s*" argument parser in
Vinay Sajip35e3b032008-09-01 14:33:59 +00002952 PyArg_ParseTuple and friends, which occurred when the argument for "s*"
Antoine Pitroud4ae97b2008-08-29 18:39:48 +00002953 was correctly parsed but parsing of subsequent arguments failed.
2954
Vinay Sajip35e3b032008-09-01 14:33:59 +00002955- Issue #2534: speed up isinstance() and issubclass() by 50-70%, so as to
Antoine Pitrou0668c622008-08-26 22:42:08 +00002956 match Python 2.5 speed despite the __instancecheck__ / __subclasscheck__
2957 mechanism. In the process, fix a bug where isinstance() and issubclass(),
2958 when given a tuple of classes as second argument, were looking up
2959 __instancecheck__ / __subclasscheck__ on the tuple rather than on each
2960 type object.
2961
Neal Norwitz18aa3882008-08-24 05:04:52 +00002962- Fix crashes on memory allocation failure found with failmalloc.
2963
2964- Fix memory leaks found with valgrind and update suppressions file.
2965
2966- Fix compiler warnings in opt mode which would lead to invalid memory reads.
2967
2968- Fix problem using wrong name in decimal module reported by pychecker.
2969
Christian Heimes7d4c3172008-08-22 19:47:25 +00002970- Silenced another compiler warning about a used but not defined
2971 function 'stringlib_contains_obj'.
2972
Benjamin Peterson712ee922008-08-24 18:10:20 +00002973- Added warnings on the use of ``__getslice__``, ``__setslice__``, or
2974 ``__delslice__``.
2975
Gregory P. Smith2bb25cc2008-09-02 05:29:51 +00002976- Issue #3678: Correctly pass LDFLAGS and LDLAST to the linker on shared
2977 library targets in the Makefile.
2978
Gregory P. Smith980b99b2008-09-07 05:15:18 +00002979- Issue #1204: The configure script now tests for additional libraries
2980 that may be required when linking against readline. This fixes issues
2981 with x86_64 builds on some platforms (a few Linux flavors and OpenBSD).
2982

Amaury Forgeot d'Arc24cb3822008-09-11 20:56:13 +00002991- Issue #3640: Pickling a list or a dict uses less local variables, to reduce
2992 stack usage in the case of deeply nested objects.
2993
Guido van Rossume3c4fd92008-09-10 14:27:00 +00002994- Issue #3629: Fix sre "bytecode" validator for an end case.
2995
Martin v. Löwis24329ba2008-09-10 13:38:12 +00002996- Issue #3811: The Unicode database was updated to 5.1.
2997
Nick Coghland2e09382008-09-11 12:11:06 +00002998- Issue #3781: Further warnings.catch_warnings() cleanup to prevent
2999 silent misbehaviour when a single instance is nested in multiple
3000 with statements, or when the methods are invoked in the wrong order.
3001

3003
Nick Coghland2e09382008-09-11 12:11:06 +00003004- Issue #3781: Clean up the API for warnings.catch_warnings() by having it
Brett Cannon672237d2008-09-09 00:49:16 +00003005 return a list or None rather than a custom object.
3006
Benjamin Peterson6ac7d7c2008-09-06 19:28:11 +00003007- Issue #1638033: Cookie.Morsel gained the httponly attribute.
3008
Antoine Pitrouebcd0ce2008-09-05 23:30:23 +00003009- Issue #3535: zipfile couldn't read some zip files larger than 2GB.

3014 its symbolic link.
3015
Vinay Sajip65d66e12008-09-04 07:31:21 +00003016- Issue #3772: Fixed regression problem in StreamHandler.emit().

3031 warnings.catch_warnings() along with some API cleanup. Expanding the tests
3032 for catch_warnings() also led to an improvement in the raising of a
3033 DeprecationWarning related to warnings.warn_explicit().
3034
Benjamin Peterson973e6c22008-09-01 23:12:58 +00003035- The deprecation warnings for the old camelCase threading API were removed.

3040
Christian Heimes1cc69632008-08-22 20:10:27 +00003041- Fixed two format strings in the _collections module.
3042

3044 directory.
Benjamin Petersonf22c26e2008-09-01 14:13:43 +00003045
Gregory P. Smithd7122032008-09-02 05:36:11 +00003046- Issue #3708: os.urandom no longer goes into an infinite loop when passed a
3047 non-integer floating point number.
3048
Vinay Sajip65d66e12008-09-04 07:31:21 +00003049- Issue #3110: multiprocessing fails to compiel on solaris 10 due to missing

3057
Amaury Forgeot d'Arc293924b2008-09-02 23:19:56 +00003058- Issue #2975: When compiling several extension modules with Visual Studio 2008
3059 from the same python interpreter, some environment variables would grow
3060 without limit.
3061
Benjamin Peterson37346b22008-08-23 20:27:43 +00003062- Issue #3643: Added a few more checks to _testcapi to prevent segfaults by
3063 exploitation of poor argument checking.
3064
Gerhard Häringef2276b2008-09-12 13:54:06 +00003065- sqlite3: Changed docstring of iterdump() to mark method as "Non-standard".
3066
Gerhard Häring6e1afcf2008-09-12 18:58:57 +00003067- Issue #3103: Reduced globals symbols used by sqlite3 module and made sure all
3068 remaining ones have "pysqlite_" prefix.
3069
Gerhard Häringe6872eb2008-09-12 22:33:22 +00003070- Issue #3846: Release the GIL during sqlite3_prepare calls. This improves

Nick Coghland2e09382008-09-11 12:11:06 +00003077- Issue #3781: Add test.test_support.check_warnings() as a convenience
3078 wrapper for warnings.catch_warnings() that makes it easier to check
3079 that expected warning messages are being reported.
3080
Amaury Forgeot d'Arcfeb8cad2008-09-06 20:53:51 +00003081- Issue #3796: Some tests functions were not enabled in test_float.

Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00003099What's New in Python 2.6 beta 3?
3100================================
3101
Barry Warsaw07a4a382008-08-21 01:15:08 +00003102*Release date: 20-Aug-2008*
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00003103
3104Core and Builtins
3105-----------------
3106
Guido van Rossumf8402962008-08-20 15:01:50 +00003107- Issue #1878: Remove Py_TPFLAGS_HAVE_VERSION_TAG from
3108 Py_TPFLAGS_DEFAULT when not building the core. This means 3rd party
3109 extensions do not automatically benefit from the class attribute
3110 cache; they will have to explicitly add Py_TPFLAGS_HAVE_VERSION_TAG
3111 to their tp_flags field if they care. This is a backwards
3112 compatibility feature; in 3.0, all types will use the cache by
3113 default.
3114
Benjamin Petersonf647dc12008-08-20 01:27:30 +00003115- Keyword arguments can now follow starred arguments. (``f(a, *args,
3116 keyword=23)`` is now valid syntax.)
3117
Thomas Heller0ad5ae02008-08-19 19:25:04 +00003118- ctypes function pointers that are COM methods have a boolean True
3119 value again.
3120
Martin v. Löwisf91d46a2008-08-12 14:49:50 +00003121- Issue #3139: Make buffer-interface thread-safe wrt. PyArg_ParseTuple,
3122 by denying s# to parse objects that have a releasebuffer procedure,
3123 and introducing s*.
3124
Georg Brandl1e13ea92008-08-11 09:07:59 +00003125- Issue #3537: Fix an assertion failure when an empty but presized dict
3126 object was stored in the freelist.
3127
Mark Dickinsonb6467572008-08-04 21:30:09 +00003128- Issue #1481296: Make long(float('nan')) and int(float('nan')) raise
3129 ValueError consistently across platforms.
3130
Amaury Forgeot d'Arc39fd6722008-07-31 21:28:03 +00003131- Issue #3479: On platforms where sizeof(int) is smaller than sizeof(long)
3132 (64bit Unix, for example), unichr() would truncate its argument and return
3133 u'\x00' for unichr(2**32). Now it properly raises an OverflowError.
3134
Neal Norwitze7d8be82008-07-31 17:17:14 +00003135- Apply security patches from Apple.
3136
Amaury Forgeot d'Arc246daed2008-07-31 00:42:16 +00003137- Issue #2542: Now that issubclass() may call arbitrary code, ensure that
3138 PyErr_ExceptionMatches returns 0 when an exception occurs there.
3139
Antoine Pitrou92f82162008-07-25 22:22:08 +00003140- Issue #1819: function calls with several named parameters are now on
3141 average 35% faster (as measured by pybench).
3142
Amaury Forgeot d'Arce4921fe2008-07-21 22:00:38 +00003143- Issue #2378: An unexpected UnboundLocalError or NameError could appear when
3144 the python debugger steps into a class statement: the free variables (local
3145 variables defined in an outer scope) would be deleted from the outer scope.
3146
Gregory P. Smith0470bab2008-07-22 04:46:32 +00003147- Issue #2620: Overflow checking when allocating or reallocating memory
3148 was not always being done properly in some python types and extension
3149 modules. PyMem_MALLOC, PyMem_REALLOC, PyMem_NEW and PyMem_RESIZE have
3150 all been updated to perform better checks and places in the code that
3151 would previously leak memory on the error path when such an allocation
3152 failed have been fixed.
3153
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00003154Library
3155-------
3156
Hirokazu Yamamoto838c79f2008-08-20 13:14:07 +00003157- Issue #3612: Added some missing basic types in ctypes.wintypes.
3158
Benjamin Petersone977ad42008-08-20 01:42:01 +00003159- The methods ``is_in_tuple()``, ``is_vararg()``, and ``is_keywordarg()`` of
3160 symtable.Symbol have been deprecated for removal in 3.0 and the next release.
3161
Amaury Forgeot d'Arc351ffb82008-08-18 19:23:47 +00003162- Issue #2234: distutils failed for some versions of the cygwin compiler. The
3163 version reported by these tools does not necessarily follow the python
3164 version numbering scheme, so the module is less strict when parsing it.
3165
Nick Coghlanf70385a2008-08-18 12:42:46 +00003166- Issue #2235: Added Py3k warnings for types which will become unhashable
3167 under the stricter __hash__ inheritance rules in 3.0. Several types
3168 which did not meet the rules for hash invariants and were already
3169 unhashable in 3.0 have now been explicitly flagged as unhashable in
3170 2.6 as well (collections.Mapping, collections.Set, unittest.TestSuite,
3171 xml.dom.minidom.NamedNodeMap, numbers.Number, UserList.UserList)
3172
Brett Cannon88f801d2008-08-18 00:46:22 +00003173- Update __all__ for cookielib, csv, os, urllib2, and weakref to include things
3174 imported into the module but exposed as part of the module's API.
3175
Brett Cannon7b96f072008-08-18 00:41:11 +00003176- Remove an unneeded import of abc.ABCMeta from 'inspect'.
3177
Brett Cannon46225e72008-08-18 00:36:52 +00003178- Remove unneeded imports of 'sys' and 'warnings' from 'io'.

Brett Cannon25c9d6a2008-08-17 22:10:11 +00003180- Remove unneeded imports of 'warnings' from shelve, filecmp, and dummy_thread.
3181
Hirokazu Yamamoto41a81eb2008-08-17 13:10:46 +00003182- Issue #3575: Incremental decoder's decode function now takes bytearray
3183 by using 's*' instead of 't#'.
3184
Mark Dickinson3e4caeb2009-02-21 20:27:01 +00003185- Issue #2222: Fixed reference leak when occurred os.rename()
Hirokazu Yamamoto7f30a682008-08-17 09:46:56 +00003186 fails unicode conversion on 2nd parameter. (windows only)
3187
Facundo Batista94f243a2008-08-17 03:38:39 +00003188- Issue 2464. urllib2 now supports a malformation in the URL received
3189 in a redirect.
3190
Brett Cannonabe423e2008-08-16 21:47:07 +00003191- Silence the DeprecationWarning raised when importing mimetools in
Brett Cannon721b1452008-08-16 22:00:27 +00003192 BaseHTTPServer, cgi (and rfc822), httplib.
Brett Cannonabe423e2008-08-16 21:47:07 +00003193
Facundo Batistaeb90b782008-08-16 14:44:07 +00003194- Issue #2776: fixed small issue when handling an URL with double slash
3195 after a 302 response in the case of not going through a proxy.
3196
Antoine Pitroub90a8be2008-08-15 21:03:21 +00003197- Issue #2676: in the email package, content-type parsing was hanging on
3198 pathological input because of quadratic or exponential behaviour of a
3199 regular expression.
3200
Antoine Pitrou11ec65d2008-08-14 21:04:30 +00003201- Issue #3476: binary buffered reading through the new "io" library is now
3202 thread-safe.
3203
Brett Cannonbf3157b2008-08-14 05:00:03 +00003204- Silence the DeprecationWarning of rfc822 when it is imported by mimetools
3205 since mimetools itself is deprecated. Because modules are cached, all
3206 subsequent imports of rfc822 will not raise a visible DeprecationWarning.
3207
Antoine Pitrou9fcd4b32008-08-11 17:21:36 +00003208- Issue #3134: shutil referenced undefined WindowsError symbol.
3209
Robert Schuppenies14646332008-08-10 11:01:53 +00003210- Issue #1342811: Fix leak in Tkinter.Menu.delete. Commands associated to
3211 menu entries were not deleted.
3212
Brett Cannon83e81842008-08-09 23:30:55 +00003213- Copied the implementation of reduce() to _functools.reduce() to have a
3214 version that did not raise a DeprecationWarning under -3.
3215
Antoine Pitrou76b8bee2008-08-09 17:27:23 +00003216- Issue #3205: When iterating over a BZ2File fails allocating memory, raise

3220 to _sre.compile() will now be rejected. This should not affect anybody
3221 since the re.compile() function never generates invalid re-bytecode.

Benjamin Peterson01a24322008-07-28 23:35:27 +00003241- Issue #2523: Fix quadratic behaviour when read()ing a binary file without
Antoine Pitroude781a42008-08-09 12:43:23 +00003242 asking for a specific length. This problem only affected files opened
3243 using the new "io" module, not the built-in open() function.

3286
Nick Coghlan2a0c2b12008-08-04 12:47:17 +00003287- Issue #643841: The language reference now provides more detailed

3299-----------------
3300
Georg Brandl3e483f62008-07-16 22:57:41 +00003301- Issue #3156: Fix inconsistent behavior of the bytearray type: all
3302 its methods now allow for items objects that can be converted to
3303 an integer using operator.index().
3304
Mark Dickinson64b7e502008-07-16 09:40:03 +00003305- Issue #3360: Fix incorrect parsing of '020000000000.0', which
3306 produced a ValueError instead of giving the correct float.
3307
Eric Smitha5fa5a22008-07-16 00:11:49 +00003308- Issue #3083: Add alternate (#) formatting for bin, oct, hex output
3309 for str.format(). This adds the prefix 0b, 0o, or 0x, respectively.
3310
Mark Dickinson7103aa42008-07-15 19:08:33 +00003311- Issue #3008: the float type has a new instance method 'float.hex'
3312 and a new class method 'float.fromhex' to convert floating-point
3313 numbers to and from hexadecimal strings, respectively.
3314
Nick Coghlan6d6bd442008-07-15 15:40:22 +00003315- Issue #2235: __hash__ is once again inherited by default. To allow
3316 collections.Hashable to remain meaningful in the presence of the
3317 default hash implementation (object.__hash__), it is now possible
3318 to explicit block inheritance of hash by setting __hash__=None at
3319 the Python level, or tp_hash=PyObject_HashNotImplemented at the C
3320 level.
3321
Nick Coghlanb028f502008-07-13 14:52:36 +00003322- Issue #3221: Issue a RuntimeWarning instead of raising SystemError if
3323 the parent module cannot be found while performing an absolute import.
3324 This means that an incorrectly defined __package__ attribute will
3325 now only prevent relative imports in that module rather than causing
3326 all imports from that module to fail.
3327
Nick Coghlan14ff9942008-07-08 14:21:42 +00003328- Issue #2517: Allow unicode messages in Exceptions again by correctly

3338 another thread's dictionary.
3339
Mark Dickinson1ec2fcd2008-06-20 14:53:43 +00003340- Issue #3004: Minor change to slice.indices(): the start and stop
3341 arguments are now treated identically, making the behaviour easier
3342 to describe and understand. For example, slice(None, -10,
3343 1).indices(9) now returns (0, 0, 1) instead of (0, -1, 1), and
3344 slice(None, 10, -1).indices(10) returns (9, 9, -1) instead of (9,
3345 10, -1).
3346
Georg Brandl278fc502008-07-19 12:46:12 +00003347- Issue #3219: Calling a function with repeated keyword arguments,
3348 f(a=2, a=23), would not cause a syntax error. This was a regression
3349 from 2.4 caused by the switch to the new compiler.

Amaury Forgeot d'Arc0f7cddc2008-07-06 21:34:39 +00003387- Issue #839496: SimpleHTTPServer used to open text files in text mode. This is
3388 both unnecessary (HTTP allows text content to be sent in several forms) and
Andrew M. Kuchlingcc3f2b12008-07-10 14:43:31 +00003389 wrong because the actual transmitted size could differ from the
Amaury Forgeot d'Arc0f7cddc2008-07-06 21:34:39 +00003390 content-length. The problem had been corrected in the 2.4 branch, but never

Nick Coghlanc060b0e2008-07-02 13:09:19 +00003406- Issue #3190: Pydoc now hides the automatic module attribute __package__ (the

3794
Brett Cannonb61d8012008-05-11 23:39:04 +00003795- ``Lib/lib-old`` is now added to sys.path.
3796
Ronald Oussoren5640ce22008-06-05 12:58:24 +00003797- On MacOS X it is now possible to install the framework in 64-bit
3798 mode or even as a 4-way universal binary (that is, PPC, i386,
Georg Brandl5cc774e2008-06-11 20:28:06 +00003799 PPC64 and x86_64 support in one binary).
Ronald Oussoren5640ce22008-06-05 12:58:24 +00003800
3801 This is controlled by the configure argument ``--with-universal-archs``:
3802
3803 - ``--with-universal-archs=all``: install 4-way universal
3804
3805 - ``--with-universal-archs=32-bit``: install 2-way universal, 32-bit (the default)
3806
3807 - ``--with-universal-archs=64-bit``: install 2-way universal, 64-bit
3808
3809 This option should be used in combination with ``--enable-universalsdk=``.
3810
3811 NOTE: 64-bit and 4-way builds are only suppported on Mac OS X 10.5 (or later).

Christian Heimes7a990612008-05-26 13:15:11 +00003820
3821- The PyString functions have been renamed to PyBytes. A batch of
3822 defines were added so that the linker still sees the original
3823 PyString names.

Georg Brandl3ee81df2008-05-17 18:14:43 +00003861- Issue #1631171: Re-implement the 'warnings' module in C (the
3862 original Python code has been kept as backup). This will allow for
3863 using the 'warning's machinery in such places as the parser where
3864 use of pure Python code is not possible. Both the ``showarning()``
3865 and ``formatwarning()`` gain an optional 'line' argument which is
3866 not called by default for backwards-compatibility reasons. Setting
3867 ``warnings.showwarning()`` to an implementation that lacks support
3868 for the ``line`` argument will raise a DeprecationWarning.

3892
Gregory P. Smithd59fefb2008-04-22 08:11:33 +00003893- The getpass module has been improved on Unix. It now uses /dev/tty
3894 by default and uses stderr instead of stdout. A GetPassWarning is
3895 issued when input echo cannot be controlled.

Georg Brandl3ee81df2008-05-17 18:14:43 +00003910- Issue #2513: distutils on Windows is now capable of cross-compiling
Mark Hammond495cf992008-04-07 01:53:39 +00003911 extension modules between 32 and 64 bit platforms. See the distutls

3924 so the controlled environment will more closely mirror the typical
3925 script environment. This supports setup.py scripts that refer to
3926 data files.

Georg Brandl3ee81df2008-05-17 18:14:43 +00003931- Issue #2550: The approach used by client/server code for obtaining
3932 ports to listen on in network-oriented tests has been refined in an
3933 effort to facilitate running multiple instances of the entire
3934 regression test suite in parallel without issue.
3935 test_support.bind_port() has been fixed such that it will always
3936 return a unique port -- which wasn't always the case with the
3937 previous implementation, especially if socket options had been set
3938 that affected address reuse (i.e. SO_REUSEADDR, SO_REUSEPORT). The
3939 new implementation of bind_port() will actually raise an exception
3940 if it is passed an AF_INET/SOCK_STREAM socket with either the
3941 SO_REUSEADDR or SO_REUSEPORT socket option set. Furthermore, if
3942 available, bind_port() will set the SO_EXCLUSIVEADDRUSE option on
3943 the socket it's been passed. This currently only applies to
3944 Windows. This option prevents any other sockets from binding to the
3945 host/port we've bound to, thus removing the possibility of the
3946 'non-deterministic' behaviour, as Microsoft puts it, that occurs
3947 when a second SOCK_STREAM socket binds and accepts to a host/port
3948 that's already been bound by another socket. The optional preferred
3949 port parameter to bind_port() has been removed. Under no
3950 circumstances should tests be hard coding ports!
3951
3952 test_support.find_unused_port() has also been introduced, which will
3953 pass a temporary socket object to bind_port() in order to obtain an
3954 unused port. The temporary socket object is then closed and
3955 deleted, and the port is returned. This method should only be used
3956 for obtaining an unused port in order to pass to an external program
3957 (i.e. the -accept [port] argument to openssl's s_server mode) or as
3958 a parameter to a server-oriented class that doesn't give you direct
3959 access to the underlying socket used.
3960
3961 Finally, test_support.HOST has been introduced, which should be used
3962 for the host argument of any relevant socket calls (i.e. bind and
3963 connect).
Trent Nelsone41b0062008-04-08 23:47:30 +00003964
3965 The following tests were updated to following the new conventions:
Georg Brandl3ee81df2008-05-17 18:14:43 +00003966 test_socket, test_smtplib, test_asyncore, test_ssl, test_httplib,
Trent Nelsone41b0062008-04-08 23:47:30 +00003967 test_poplib, test_ftplib, test_telnetlib, test_socketserver,
3968 test_asynchat and test_socket_ssl.
3969
Georg Brandl3ee81df2008-05-17 18:14:43 +00003970 It is now possible for multiple instances of the regression test
3971 suite to run in parallel without issue.

4238-----------------
4239
Fred Drakea8ee94b2008-03-01 02:45:07 +00004240- Issue #2051: pyc and pyo files are no longer created with permission
Barry Warsaw52973612008-03-01 02:23:38 +00004241 644. The mode is now inherited from the py file.

Christian Heimes5224d282008-02-23 15:01:05 +00004246
Vinay Sajipb7edfc42008-04-02 21:10:23 +00004247- Issue #1881: An internal parser limit has been increased. Also see
Facundo Batistafc2d0102008-02-23 12:01:13 +00004248 issue 215555 for a discussion.
4249
Eric Smitha73fbe72008-02-23 03:09:44 +00004250- Added the future_builtins module, which contains hex() and oct().
4251 These are the PEP 3127 version of these functions, designed to be
4252 compatible with the hex() and oct() builtins from Python 3.0. They
4253 differ slightly in their output formats from the existing, unchanged
4254 Python 2.6 builtins. The expected usage of the future_builtins
4255 module is:
4256 from future_builtins import hex, oct
4257
Eric Smith7ef40bf2008-02-20 23:34:22 +00004258- Issue #1600: Modifed PyOS_ascii_formatd to use at most 2 digit
4259 exponents for exponents with absolute value < 100. Follows C99
4260 standard. This is a change on Windows, which would use 3 digits.
4261 Also, added 'n' to the formats that PyOS_ascii_formatd understands,
4262 so that any alterations it does to the resulting string will be
4263 available in stringlib/formatter.h (for float.__format__).
4264
Eric Smith5a3c1352008-02-19 13:21:56 +00004265- Implemented PEP 3101, Advanced String Formatting. This adds a new
4266 builtin format(); a format() method for str and unicode; a
4267 __format__() method to object, str, unicode, int, long, float, and
4268 datetime; the class string.Formatter; and the C API
4269 PyObject_Format().
4270
Georg Brandl3ee81df2008-05-17 18:14:43 +00004271- Fixed several potential crashes, all caused by specially crafted
4272 __del__ methods exploiting objects in temporarily inconsistent
4273 state.
Amaury Forgeot d'Arc632fad32008-02-16 20:55:24 +00004274
Vinay Sajipb7edfc42008-04-02 21:10:23 +00004275- Issue #2115: Important speedup in setting __slot__ attributes. Also
Georg Brandl3ee81df2008-05-17 18:14:43 +00004276 prevent a possible crash: an Abstract Base Class would try to access
4277 a slot on a registered virtual subclass.

Georg Brandl3ee81df2008-05-17 18:14:43 +00004282- Clear all free lists during a gc.collect() of the highest generation
4283 in order to allow pymalloc to free more arenas. Python may give back
4284 memory to the OS earlier.
Christian Heimes3b718a72008-02-14 12:47:33 +00004285
Georg Brandl3ee81df2008-05-17 18:14:43 +00004286- Issue #2045: Fix an infinite recursion triggered when printing a
4287 subclass of collections.defaultdict, if its default_factory is set
4288 to a bound method.
Amaury Forgeot d'Arcb01aa432008-02-08 00:56:02 +00004289
Christian Heimesf75dbef2008-02-08 00:11:31 +00004290- Fixed a minor memory leak in dictobject.c. The content of the free
4291 list was not freed on interpreter shutdown.
4292
Georg Brandl21e99f42010-03-07 15:23:59 +00004293- Limit free list of method and built-in function objects to 256
Georg Brandl3ee81df2008-05-17 18:14:43 +00004294 entries each.
Christian Heimes6075a822008-02-06 12:44:34 +00004295
Georg Brandl3ee81df2008-05-17 18:14:43 +00004296- Patch #1953: Added ``sys._compact_freelists()`` and the C API
4297 functions ``PyInt_CompactFreeList`` and ``PyFloat_CompactFreeList``
Christian Heimes422051a2008-02-04 18:00:12 +00004298 to compact the internal free lists of pre-allocted ints and floats.
4299
Georg Brandl3ee81df2008-05-17 18:14:43 +00004300- Issue #1983: Fixed return type of fork(), fork1() and forkpty()
4301 calls. Python expected the return type int but the fork familie
4302 returns pi_t.
Christian Heimes951cc0f2008-01-31 23:08:23 +00004303
Georg Brandl3ee81df2008-05-17 18:14:43 +00004304- Issue #1678380: Fix a bug that identifies 0j and -0j when they
4305 appear in the same code unit.
Mark Dickinson105be772008-01-31 22:17:37 +00004306
Georg Brandl3ee81df2008-05-17 18:14:43 +00004307- Issue #2025: Add tuple.count() and tuple.index() methods to comply
4308 with the collections.Sequence API.
Raymond Hettinger5b07ebc2008-02-07 00:54:20 +00004309
Georg Brandl3ee81df2008-05-17 18:14:43 +00004310- Patch #1970 by Antoine Pitrou: Speedup unicode whitespace and
4311 linebreak detection
Christian Heimes4d4f2702008-01-30 11:32:37 +00004312
Georg Brandl3ee81df2008-05-17 18:14:43 +00004313- Added ``PyType_ClearCache()`` and ``sys._clear_type_cache`` to clear
4314 the internal lookup cache for ref leak tests.
Christian Heimes908caac2008-01-27 23:34:59 +00004315
Georg Brandl3ee81df2008-05-17 18:14:43 +00004316- Patch #1473257: generator objects gain a gi_code attribute. This is
4317 the same object as the func_code attribute of the function that
4318 produced the generator.
Georg Brandl0cdf9a32008-01-26 14:14:20 +00004319
Georg Brandl3ee81df2008-05-17 18:14:43 +00004320- Issue #1920: "while 0" statements were completely removed by the
4321 compiler, even in the presence of an "else" clause, which is
4322 supposed to be run when the condition is false. Now the compiler
4323 correctly emits bytecode for the "else" suite.
Amaury Forgeot d'Arc31eaafe2008-01-24 22:59:25 +00004324
Guido van Rossumeead05f2008-01-24 18:21:02 +00004325- A few crashers fixed: weakref_in_del.py (issue #1377858);
4326 loosing_dict_ref.py (issue #1303614, test67.py);
4327 borrowed_ref_[34].py (not in tracker).
4328
Vinay Sajipd7cf32e2008-01-24 12:43:33 +00004329- Issue #1069410: The "can't load dll" message box on Windows is
Christian Heimesb2302ba2008-01-23 17:15:06 +00004330 suppressed while an extension is loaded by calling SetErrorMode in
4331 dynload_win.c. The error is still reported properly.
4332
Georg Brandl3ee81df2008-05-17 18:14:43 +00004333- Issue #1915: Python compiles with --enable-unicode=no again. However
Christian Heimes082c9b02008-01-23 14:20:50 +00004334 several extension methods and modules do not work without unicode
4335 support.
4336
Georg Brandl26543b12008-01-21 18:36:51 +00004337- Issue #1882: when compiling code from a string, encoding cookies in the
4338 second line of code were not always recognized correctly.
4339
Georg Brandl14404b62008-01-19 19:27:05 +00004340- Issue #1679: "0x" was taken as a valid integer literal.
4341
Georg Brandl6caad7d2008-01-26 14:19:22 +00004342- Issue #1865: ``bytes`` as an alias for ``str`` and b"" as an alias "" were
Christian Heimes288e89a2008-01-18 18:24:07 +00004343 added.
4344
Christian Heimesc94e2b52008-01-14 04:13:37 +00004345- sys.float_info / PyFloat_GetInfo: The floating point information
4346 object was converted from a dict to a specialized structseq object.
4347
Georg Brandl3ee81df2008-05-17 18:14:43 +00004348- Patch #1816: Added sys.flags structseq. It exposes the status of
4349 most command line arguments and PYTHON* environment variables.
Christian Heimesf31b69f2008-01-14 03:42:48 +00004350
Georg Brandl3ee81df2008-05-17 18:14:43 +00004351- Objects/structseq.c: Implemented new structseq representation. The
4352 patch makes structseqs (e.g. the return value of os.stat) more
4353 readable.
Christian Heimes9c201962008-01-14 03:33:52 +00004354
Georg Brandl3ee81df2008-05-17 18:14:43 +00004355- Patch #1700288: added a type attribute cache that caches method
4356 accesses, resulting in speedups in heavily object-oriented code.
Amaury Forgeot d'Arce4c270c2008-01-14 00:29:41 +00004357
Neal Norwitz3fc15b82008-01-10 05:42:58 +00004358- Bug #1776: __import__() no longer accepts filenames on any platform.
4359 The first parameter to __import__() must be a valid module name.
Christian Heimes3403f152008-01-09 19:56:33 +00004360
Georg Brandlaed6c662008-01-07 17:25:53 +00004361- Patch #1668: renamed THREADDEBUG envvar to PYTHONTHREADDEBUG.
4362
Georg Brandl3ee81df2008-05-17 18:14:43 +00004363- Patch #602345: Add -B command line option, PYTHONDONTWRITEBYTECODE
4364 envvar and sys.dont_write_bytecode attribute. All these can be set
4365 to forbid Python to attempt to write compiled bytecode files.
Georg Brandl2da0fce2008-01-07 17:09:35 +00004366
Georg Brandl3ee81df2008-05-17 18:14:43 +00004367- Improve some exception messages when Windows fails to load an
4368 extension module. Now we get for example '%1 is not a valid Win32
4369 application' instead of 'error code 193'.
Amaury Forgeot d'Arce0b76952008-01-04 02:04:15 +00004370
Georg Brandl3ee81df2008-05-17 18:14:43 +00004371- Bug #1481296: Fixed long(float('nan')) != 0L.

Georg Brandl3ee81df2008-05-17 18:14:43 +00004373- Issue #1640: Added math.isinf(x), math.isnan(x) and math.copysign(x,
4374 y) functions.
Christian Heimese2ca4242008-01-03 20:23:15 +00004375
Christian Heimes0a8143f2007-12-18 23:22:54 +00004376- Issue #1635: Platform independent creation and representation of NaN
Georg Brandl3ee81df2008-05-17 18:14:43 +00004377 and INF. float("nan"), float("inf") and float("-inf") now work on
4378 every platform with IEEE 754 semantics.
Christian Heimes0a8143f2007-12-18 23:22:54 +00004379
Georg Brandl3ee81df2008-05-17 18:14:43 +00004380- Compiler now generates simpler and faster code for dictionary
4381 literals. The oparg for BUILD_MAP now indicates an estimated
4382 dictionary size. There is a new opcode, STORE_MAP, for adding
4383 entries to the dictionary.

Andrew M. Kuchling395fe442007-12-05 13:27:20 +00004393- Issue #1553: An erroneous __length_hint__ can make list() raise a
Christian Heimes7cc1c6f2007-12-05 12:52:34 +00004394 SystemError.
4395
Nick Coghlanef01d822007-12-03 12:55:17 +00004396- PEP 366: Allow explicit relative imports when executing modules

Georg Brandl3ee81df2008-05-17 18:14:43 +00004412- Patch #1739468: Directories and zipfiles containing a __main__.py
4413 file can now be directly executed by passing their name to the
4414 interpreter. The directory/zipfile is automatically inserted as the
4415 first entry in sys.path.
Nick Coghlan327a39b2007-11-18 11:56:28 +00004416
Georg Brandl3ee81df2008-05-17 18:14:43 +00004417- Issue #1265: Fix a problem with sys.settrace, if the tracing
4418 function uses a generator expression when at the same time the
4419 executed code is closing a paused generator.
Amaury Forgeot d'Arc0d75f092007-11-13 21:54:28 +00004420
Raymond Hettinger1760c8a2007-11-08 02:52:43 +00004421- sets and frozensets now have an isdisjoint() method.
4422
Raymond Hettinger3f8caa32007-10-24 01:28:33 +00004423- optimize the performance of builtin.sum().
4424
Neal Norwitz44f326e2007-10-05 05:29:17 +00004425- Fix warnings found by the new version of the Coverity checker.
4426
Georg Brandl21e99f42010-03-07 15:23:59 +00004427- The enumerate() built-in function is no longer bounded to sequences
Georg Brandl3ee81df2008-05-17 18:14:43 +00004428 smaller than LONG_MAX. Formerly, it raised an OverflowError. Now,
4429 automatically shifts from ints to longs.
Raymond Hettinger8f669372007-10-03 21:18:11 +00004430
Georg Brandl3ee81df2008-05-17 18:14:43 +00004431- Issue #1686386: Tuple's tp_repr did not take into account the
4432 possibility of having a self-referential tuple, which is possible
4433 from C code. Nor did object's tp_str consider that a type's tp_str
4434 could do something that could lead to an inifinite recursion.
4435 Py_ReprEnter() and Py_EnterRecursiveCall(), respectively, fixed the
4436 issues.
Brett Cannon0b14f242007-09-30 19:45:10 +00004437
Georg Brandl3ee81df2008-05-17 18:14:43 +00004438- Issue #1164: It was possible to trigger deadlock when using the
4439 'print' statement to write to a file since the GIL was not released
4440 as needed. Now PyObject_Print() does the right thing along with
4441 various tp_print implementations of the built-in types and those in
4442 the collections module.
Brett Cannon01531592007-09-17 03:28:34 +00004443
Georg Brandl3ee81df2008-05-17 18:14:43 +00004444- Issue #1147: Exceptions were directly allowing string exceptions in
4445 their throw() method even though string exceptions no longer
4446 allowed.
Brett Cannon4c20bc42007-09-11 21:02:28 +00004447
Georg Brandl3ee81df2008-05-17 18:14:43 +00004448- Issue #1096: Prevent a segfault from getting the repr of a very
4449 deeply nested list by using the recursion counter.
Brett Cannona0c05512007-09-10 21:38:27 +00004450
Brett Cannon1e534b52007-09-07 04:18:30 +00004451- Issue #1202533: Fix infinite recursion calls triggered by calls to
Georg Brandl3ee81df2008-05-17 18:14:43 +00004452 PyObject_Call() never calling back out to Python code to trigger
4453 recursion depth updates/checks. Required the creation of a static
4454 RuntimeError instance in case normalizing an exception put the
4455 recursion check value past its limit. Fixes crashers
4456 infinite_rec_(1|2|4|5).py.
Brett Cannon1e534b52007-09-07 04:18:30 +00004457
Georg Brandl3ee81df2008-05-17 18:14:43 +00004458- Patch #1031213: Decode source line in SyntaxErrors back to its

Neal Norwitz0ac60192007-05-27 04:08:54 +00004471- Add new attribute names for function objects. All the func_* become
Georg Brandl3ee81df2008-05-17 18:14:43 +00004472 __*__ attributes. (Some already existed, e.g., __doc__ and
4473 __name__.)
Neal Norwitz0ac60192007-05-27 04:08:54 +00004474
Neal Norwitz8b2bfbc2007-05-23 06:35:32 +00004475- Add -3 option to the interpreter to warn about features that are
4476 deprecated and will be changed/removed in Python 3.0.
4477
Georg Brandl2134e752007-05-21 20:34:16 +00004478- Patch #1686487: you can now pass any mapping after '**' in function
4479 calls.
4480
Collin Winter62903052007-05-18 23:11:24 +00004481- except clauses may now be spelled either "except E, target:" or
Georg Brandl3ee81df2008-05-17 18:14:43 +00004482 "except E as target:". This is to provide forwards compatibility
4483 with Python 3.0.
Collin Winter62903052007-05-18 23:11:24 +00004484
Brett Cannon229cee22007-05-05 01:34:02 +00004485- Deprecate BaseException.message as per PEP 352.
4486
Georg Brandl3ee81df2008-05-17 18:14:43 +00004487- Issue #1303614: don't expose object's __dict__ when the dict is
Georg Brandl21e99f42010-03-07 15:23:59 +00004488 inherited from a built-in base.
Armin Rigo9790a272007-05-02 19:23:31 +00004489
Vinay Sajip8549ce32007-05-06 17:53:37 +00004490- When __slots__ are set to a unicode string, make it work the same as
Neal Norwitzcbd9ee62007-04-14 05:25:50 +00004491 setting a plain string, ie don't expand to single letter identifiers.
4492
Raymond Hettinger13936692007-04-11 18:40:58 +00004493- Request #1191699: Slices can now be pickled.
4494
Raymond Hettinger4db5fe92007-04-12 04:10:00 +00004495- Request #1193128: str.translate() now allows a None argument for
4496 translations that only remove characters without re-mapping the
4497 remaining characters.
4498
Georg Brandl5cb76c12007-03-21 09:00:39 +00004499- Patch #1682205: a TypeError while unpacking an iterable is no longer
4500 masked by a generic one with the message "unpack non-sequence".
4501
Neal Norwitzaa754b72007-03-21 06:39:48 +00004502- Remove unused file Python/fmod.c.
4503
Guido van Rossum143b5642007-03-23 04:58:42 +00004504- Bug #1683368: The object.__init__() and object.__new__() methods are
4505 now stricter in rejecting excess arguments. The only time when
4506 either allows excess arguments is when it is not overridden and the
4507 other one is. For backwards compatibility, when both are
4508 overridden, it is a deprecation warning (for now; maybe a Py3k
Guido van Rossum234b1ff2007-03-23 19:39:01 +00004509 warning later). Also, type.__init__() insists on the same signature
4510 as supported by type.__new__().
Guido van Rossum143b5642007-03-23 04:58:42 +00004511
Georg Brandl3ee81df2008-05-17 18:14:43 +00004512- Patch #1675423: PyComplex_AsCComplex() now tries to convert an
4513 object to complex using its __complex__() method before falling back
4514 to the __float__() method. Therefore, the functions in the cmath
4515 module now can operate on objects that define a __complex__()
4516 method.
Georg Brandl2b869942007-03-17 16:08:45 +00004517
Georg Brandl3ee81df2008-05-17 18:14:43 +00004518- Patch #1623563: allow __class__ assignment for classes with
4519 __slots__. The old and the new class are still required to have the
4520 same slot names.

4526 ``object.__reduce_ex__()`` is called with an object that is faking
4527 its type.

4533
Georg Brandl7b9c5552007-03-12 14:30:05 +00004534- Bug #1678647: write a newline after printing an exception in any
4535 case, even when converting the value to a string failed.
4536
Georg Brandl871f1bc2007-03-12 13:17:36 +00004537- The dir() function has been extended to call the __dir__() method on
Georg Brandl3ee81df2008-05-17 18:14:43 +00004538 its argument, if it exists. If not, it will work like before. This
4539 allows customizing the output of dir() in the presence of a
4540 __getattr__().

Georg Brandl3ee81df2008-05-17 18:14:43 +00005064 the client's request was successfully received, understood, and

5076 work started with create_connection() and timeout in httplib, and

5078
Vinay Sajip8549ce32007-05-06 17:53:37 +00005079- Patch #1676823: Added create_connection() to socket.py, which may be

Georg Brandl3ee81df2008-05-17 18:14:43 +00005105 AttributeError instead of an IOError when the server's response
5106 didn't contain a valid HTTP status line.

Georg Brandl3ee81df2008-05-17 18:14:43 +00005140 are set for invalid interpolation sequences that would lead to
5141 errors on reading back those values.

5197 TestCase and TestSuite subclasses (not instances) are no longer

Georg Brandl3ee81df2008-05-17 18:14:43 +00005590 time so that opening a database previously created with the DB_DUP
5591 or DB_DUPSORT flag set will keep the proper behavior on subsequent
5592 opens. Specifically: dictionary assignment to a DB object will
5593 replace all values for a given key when the database allows
5594 duplicate values. DB users should use DB.put(k, v) when they want
5595 to store duplicates; not DB[k] = v.

5604 behavior of quoting dots if they are the second character of any
5605 line.
