Philip Jenveyaebbaeb2010-04-06 23:24:45 +000032- Issue #7301: Add environment variable $PYTHONWARNINGS.
33
Benjamin Peterson3a1dfa22010-04-06 21:50:00 +000034- Issue #8329: Don't return the same lists from select.select when no fds are
35 changed.
36
Mark Dickinson82791672010-04-06 16:47:55 +000037- Issue #8259: 1L << (2**31) no longer produces an 'outrageous shift error'
38 on 64-bit machines. The shift count for either left or right shift is
39 permitted to be up to sys.maxsize.
40
Benjamin Peterson4ceeeb02010-04-03 22:48:51 +000041- Ensure that tokenization of identifiers is not affected by locale.

Tarek Ziadé00002952010-04-03 08:37:59 +000043- Issue #1222585: Added LDCXXSHARED for C++ support. Patch by Arfrever.
44
Benjamin Peterson1c7c11e2010-04-03 01:28:57 +000045- Raise a TypeError when trying to delete a T_STRING_INPLACE struct member.
46
Eric Smithd44b2fc2010-04-02 12:30:56 +000047- Issue #7994: Issue a PendingDeprecationWarning if object.__format__
48 is called with a non-empty format string. This is an effort to
49 future-proof user code. If a derived class does not currently
50 implement __format__ but later adds its own __format__, it would
51 most likely break user code that had supplied a format string. This
52 will be changed to a DeprecationWaring in Python 3.3 and it will be
53 an error in Python 3.4.

79 using the new attributes `ssl.OPENSSL_VERSION`, `ssl.OPENSSL_VERSION_INFO`
80 and `ssl.OPENSSL_VERSION_NUMBER`.
81
Benjamin Peterson76a23c12010-04-04 23:23:22 +000082- Issue #8310: Allow dis to examine new style classes.
83
Mark Dickinson8a950712010-04-03 15:47:46 +000084- Issue #8257: The Decimal construct now accepts a float instance
85 directly, converting that float to a Decimal of equal value:
86
87 >>> Decimal(1.1)
88 Decimal('1.100000000000000088817841970012523233890533447265625')

Raymond Hettinger34c35b22010-04-03 10:22:00 +000090- collections.Counter() now supports a subtract() method.
91
Raymond Hettingera551f312010-04-04 18:34:45 +000092- the functools module now has a total_ordering() class decorator
Andrew M. Kuchling884d0a32010-04-11 12:48:08 +000093 to simplify the specifyication of rich comparisons.
Raymond Hettingera551f312010-04-04 18:34:45 +000094
Raymond Hettingerbb006cf2010-04-04 21:45:01 +000095- The functools module also adds cmp_to_key() as a tool to transition
Raymond Hettingera551f312010-04-04 18:34:45 +000096 old-style comparison functions to new-style key-functions.

Mark Dickinson7c63eee2010-04-02 22:27:36 +000098- Issue #8294: The Fraction constructor now accepts Decimal and float
99 instances directly.

Mark Dickinsone096e822010-04-02 10:17:07 +0000101- Issue #7279: Comparisons involving a Decimal signaling NaN now
102 signal InvalidOperation instead of returning False. (Comparisons
Mark Dickinsonf3eeca12010-04-02 10:35:12 +0000103 involving a quiet NaN are unchanged.) Also, Decimal quiet NaNs
104 are now hashable; Decimal signaling NaNs remain unhashable.
Mark Dickinsone096e822010-04-02 10:17:07 +0000105
Mark Dickinson99d80962010-04-02 08:53:22 +0000106- Issue #2531: Comparison operations between floats and Decimal
107 instances now return a result based on the numeric values of the
108 operands; previously they returned an arbitrary result based on
109 the relative ordering of id(float) and id(Decimal).
110
Barry Warsawf7f2d6f2010-03-31 21:07:16 +0000111- Issue #8233: When run as a script, py_compile.py optionally takes a single
112 argument `-` which tells it to read files to compile from stdin. Each line
113 is read on demand and the named file is compiled immediately. (Original
114 patch by Piotr Ożarowski).
115
116- Issue #3135: Add inspect.getcallargs, which binds arguments to a function
117 like a normal call.
Benjamin Peterson7e213252010-03-30 17:58:13 +0000118
Florent Xicluna58b65662010-03-30 16:29:03 +0000119- Backwards incompatible change: Unicode codepoints line tabulation (0x0B) and
120 form feed (0x0C) are now considered linebreaks, as specified in Unicode
121 Standard Annex #14. See issue #7643.
Florent Xicluna22b24382010-03-30 08:24:06 +0000122 http://www.unicode.org/reports/tr14/
123
Mark Dickinson9588d992010-03-27 11:14:37 +0000124- Comparisons using one of <, <=, >, >= between a complex instance and
125 a Fractions instance now raise TypeError instead of returning
126 True/False. This makes Fraction <=> complex comparisons consistent with
127 int <=> complex, float <=> complex, and complex <=> complex comparisons.
128
Michael Foorde6410c52010-03-29 20:04:23 +0000129- Addition of ``WeakSet`` to the ``weakref`` module.

140 now silenced.
141
Florent Xicluna9e7a4c92010-03-22 16:07:38 +0000142- Issue #7703: ctypes supports both buffer() and memoryview(). The former is

149 method to LoggerAdapter.
150
Vinay Sajip31e928e2010-03-22 13:02:28 +0000151- Issue #8201: logging: Handle situation of non-ASCII and Unicode
152 logger names existing at the same time, causing a Unicode error
153 when configuration code attempted to sort the existing loggers.
154
Vinay Sajip3017a7b2010-03-22 12:33:08 +0000155- Issue #8200: logging: Handle errors when multiprocessing is not
156 fully loaded when logging occurs.

159 Also, enable the SSL_MODE_AUTO_RETRY flag on SSL sockets, so that blocking
160 reads and writes are always retried by OpenSSL itself.
Antoine Pitrou448da712010-03-21 19:33:38 +0000161
Florent Xiclunacf82fa62010-03-21 12:27:20 +0000162- Issue #8179: Fix macpath.realpath() on a non-existing path.

Victor Stinner75227342010-03-12 14:30:26 +0000179 set to an non existent program name and Python is unable to retrieve the real
Georg Brandlba83f822010-03-14 09:50:54 +0000180 program name.
Victor Stinner75227342010-03-12 14:30:26 +0000181
Vinay Sajipecfa08f2010-03-12 09:16:10 +0000182- Issue #8117: logging: Improved algorithm for computing initial rollover time
Georg Brandlba83f822010-03-14 09:50:54 +0000183 for ``TimedRotatingFileHandler`` by using the modification time of an
184 existing log file to compute the next rollover time. If the log file does
185 not exist, the current time is used as the basis for the computation.
Vinay Sajip9098ee42010-03-12 06:01:21 +0000186
Georg Brandlba83f822010-03-14 09:50:54 +0000187- Issue #6472: The ``xml.etree`` package is updated to ElementTree 1.3. The

194
Georg Brandlba83f822010-03-14 09:50:54 +0000195- Issue #7143: email: ``get_payload()`` used to strip any trailing newline from
196 a base64 transfer-encoded payload *after* decoding it; it no longer does.
197 This is a behavior change, so email's minor version number is now bumped, to
198 version 4.0.2, for the 2.7 release.
R. David Murray4617e502010-03-08 02:04:06 +0000199
Larry Hastings3b958e32010-04-02 11:18:17 +0000200- Issue #8235: _socket: Add the constant ``SO_SETFIB``. SO_SETFIB is

Mark Dickinson4846a8e2010-04-03 14:05:10 +0000224- Issue #8300: When passing a non-integer argument to struct.pack with any
225 integer format code, struct.pack first attempts to convert the non-integer
226 using its __index__ method. If that method is non-existent or raises
227 TypeError it goes on to try the __int__ method, as described below.
228
Georg Brandlba83f822010-03-14 09:50:54 +0000229- Issue #1530559: When passing a non-integer argument to struct.pack with *any*
230 integer format code (one of 'bBhHiIlLqQ'), struct.pack attempts to use the
231 argument's __int__ method to convert to an integer before packing. It also
232 produces a DeprecationWarning in this case. (In Python 2.6, the behaviour
233 was inconsistent: __int__ was used for some integer codes but not for others,
234 and the set of integer codes for which it was used differed between native
235 packing and standard packing.)

272
Larry Hastings402b73f2010-03-25 00:54:54 +0000273- Issue #7992: A replacement PyCObject API, PyCapsule, has been backported

Georg Brandlba83f822010-03-14 09:50:54 +0000530 file position when calling `truncate()`. It would previously change the file
531 position to the given argument, which goes against the tradition of

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

628Core and Builtins
629-----------------
630
Georg Brandlba83f822010-03-14 09:50:54 +0000631- The ``__complex__()`` method is now looked up on the class of instances to
632 make it consistent with other special methods.

635 `rindex`, `rsplit` and `rpartition` methods. Patch by Florent Xicluna.
636
Mark Dickinson1b34d252010-01-01 17:27:30 +0000637- Issue #5080: A number of functions and methods previously produced a
Georg Brandlba83f822010-03-14 09:50:54 +0000638 DeprecationWarning when passed a float argument where an integer was expected.
639 These functions and methods now raise TypeError instead. The majority of the
640 effects of this change are in the extension modules, but some core functions
641 and methods are affected: notably the 'chr', 'range' and 'xrange' builtins,
642 and many unicode/str methods.

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

803
Georg Brandlba83f822010-03-14 09:50:54 +0000804- Issue #7419: ``locale.setlocale()`` could crash the interpreter on Windows
805 when called with invalid values.
Amaury Forgeot d'Arcd7288712009-12-01 21:51:04 +0000806
Georg Brandlba83f822010-03-14 09:50:54 +0000807- Issue #3382: 'F' formatting for float and complex now convert the result to
808 upper case. This only affects 'inf' and 'nan', since 'f' no longer converts
809 to 'g' for large values.
Amaury Forgeot d'Arcd7288712009-12-01 21:51:04 +0000810
Georg Brandlba83f822010-03-14 09:50:54 +0000811- Remove switch from "%f" formatting to "%g" formatting for floats larger than
812 1e50 in absolute value.
Mark Dickinson9dd5e162009-11-23 20:54:09 +0000813
Georg Brandlba83f822010-03-14 09:50:54 +0000814- Remove restrictions on precision when formatting floats. E.g., "%.120g" %
815 1e-100 used to raise OverflowError, but now gives the requested 120
816 significant digits instead.
Mark Dickinson18cfada2009-11-23 18:46:41 +0000817
Georg Brandlba83f822010-03-14 09:50:54 +0000818- Add Py3k warnings for parameter names in parentheses.

Benjamin Peterson89b1a5c2009-11-19 22:58:01 +0000821
Georg Brandlba83f822010-03-14 09:50:54 +0000822- Issue #7085: Fix crash when importing some extensions in a thread on MacOSX
823 10.6.
Ronald Oussoren315cd0c2009-11-19 16:25:21 +0000824
Georg Brandlba83f822010-03-14 09:50:54 +0000825- Issue #7117: ``repr(x)`` for a float x returns a result based on the shortest
826 decimal string that's guaranteed to round back to x under correct rounding
827 (with round-half-to-even rounding mode). Previously it gave a string based on
828 rounding x to 17 decimal digits. repr(x) for a complex number behaves
829 similarly. On platforms where the correctly-rounded strtod and dtoa code is
830 not supported (see below), repr is unchanged.
Mark Dickinsonb678de82009-11-19 18:41:49 +0000831
Georg Brandlba83f822010-03-14 09:50:54 +0000832- Issue #7117: On almost all platforms: float-to-string and string-to-float
833 conversions within Python are now correctly rounded. Places these conversions
834 occur include: str for floats and complex numbers; the float and complex
835 constructors; old-style and new-style numeric formatting; serialization and
836 deserialization of floats and complex numbers using marshal, pickle and json;
837 parsing of float and imaginary literals in Python code; Decimal-to-float
838 conversion.
Mark Dickinsonb678de82009-11-19 18:41:49 +0000839
Georg Brandlba83f822010-03-14 09:50:54 +0000840 The conversions use a Python-adapted version of David Gay's well-known dtoa.c,
841 providing correctly-rounded strtod and dtoa C functions. This code is
842 supported on Windows, and on Unix-like platforms using gcc, icc or suncc as
843 the C compiler. There may be a small number of platforms on which correct
844 operation of this code cannot be guaranteed, so the code is not used: notably,
845 this applies to platforms where the C double format is not IEEE 754 binary64,
846 and to platforms on x86 hardware where the x87 FPU is set to 64-bit precision
847 and Python's configure script is unable to determine how to change the FPU
848 precision. On these platforms conversions use the platform strtod and dtoa,
849 as before.
Mark Dickinsonb678de82009-11-19 18:41:49 +0000850
Georg Brandlba83f822010-03-14 09:50:54 +0000851- Issue #7117: Backport round implementation from Python 3.x. ``round()`` now
852 uses the correctly-rounded string <-> float conversions described above (when
853 available), and so produces correctly rounded results that will display nicely
854 under the float repr. There are two related small changes: (1) round now
855 accepts any class with an ``__index__()`` method for its second argument (but
856 no longer accepts floats for the second argument), and (2) an excessively
857 large second integer argument (e.g., ``round(1.234, 10**100)``) no longer
858 raises an exception.

861
Georg Brandlba83f822010-03-14 09:50:54 +0000862- Fix several issues with ``compile()``. The input can now contain Windows and

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

1010 alignment flags to the empty presentation type. This also affects the new
1011 complex.__format__ in the same way.

1242 eventual KeyError would always report the empty ``frozenset()`` as the missing
1243 key. Now it correctly refers to the initial element.

2636Core and Builtins
2637-----------------
2638
Martin v. Löwis9fa5a282008-09-11 06:53:30 +00002639- Issue #3642: Suppress warning in obmalloc when size_t is larger than uint.
2640
Amaury Forgeot d'Arc05e34492008-09-10 22:04:45 +00002641- Issue #3743: In a few places, PY_FORMAT_SIZE_T was incorrectly used with
2642 PyString_FromFormat or PyErr_Format to display size_t values. The macro
2643 PY_FORMAT_SIZE_T is designed to select the correct format for the OS
2644 ``printf`` function, whereas PyString_FromFormat has an independent
2645 implementation and uses "%zd" on all platforms for size_t values.
2646 This makes a difference on win64, where ``printf`` needs "%Id" to display
2647 64bit values.
2648
Benjamin Peterson97179b02008-09-09 20:55:01 +00002649- Issue #3634: _weakref.ref(Exception).__init__() gave invalid return value on
2650 error.
2651
Amaury Forgeot d'Arcd3ffb892008-09-09 07:24:30 +00002652- Issue #3777: long() applied to a float object now always return a long
2653 object; previously an int would be returned for small values. the __long__
2654 method is allowed to return either an int or a long, but the behaviour of
2655 float objects should not change to respect backward compatibility.
2656
Amaury Forgeot d'Arc3571fbf2008-09-01 19:52:00 +00002657- Issue #3751: str.rpartition would perform a left-partition when called with
2658 a unicode argument.
2659
Benjamin Peterson17f03ca2008-09-01 14:18:30 +00002660- Issue #3683: Fix compilation when --without-threads is given.
2661
Antoine Pitroud4ae97b2008-08-29 18:39:48 +00002662- Issue #3668: Fix a memory leak with the "s*" argument parser in
Vinay Sajip35e3b032008-09-01 14:33:59 +00002663 PyArg_ParseTuple and friends, which occurred when the argument for "s*"
Antoine Pitroud4ae97b2008-08-29 18:39:48 +00002664 was correctly parsed but parsing of subsequent arguments failed.
2665
Vinay Sajip35e3b032008-09-01 14:33:59 +00002666- Issue #2534: speed up isinstance() and issubclass() by 50-70%, so as to
Antoine Pitrou0668c622008-08-26 22:42:08 +00002667 match Python 2.5 speed despite the __instancecheck__ / __subclasscheck__
2668 mechanism. In the process, fix a bug where isinstance() and issubclass(),
2669 when given a tuple of classes as second argument, were looking up
2670 __instancecheck__ / __subclasscheck__ on the tuple rather than on each
2671 type object.
2672
Neal Norwitz18aa3882008-08-24 05:04:52 +00002673- Fix crashes on memory allocation failure found with failmalloc.
2674
2675- Fix memory leaks found with valgrind and update suppressions file.
2676
2677- Fix compiler warnings in opt mode which would lead to invalid memory reads.
2678
2679- Fix problem using wrong name in decimal module reported by pychecker.
2680
Christian Heimes7d4c3172008-08-22 19:47:25 +00002681- Silenced another compiler warning about a used but not defined
2682 function 'stringlib_contains_obj'.
2683
Benjamin Peterson712ee922008-08-24 18:10:20 +00002684- Added warnings on the use of ``__getslice__``, ``__setslice__``, or
2685 ``__delslice__``.
2686
Gregory P. Smith2bb25cc2008-09-02 05:29:51 +00002687- Issue #3678: Correctly pass LDFLAGS and LDLAST to the linker on shared
2688 library targets in the Makefile.
2689
Gregory P. Smith980b99b2008-09-07 05:15:18 +00002690- Issue #1204: The configure script now tests for additional libraries
2691 that may be required when linking against readline. This fixes issues
2692 with x86_64 builds on some platforms (a few Linux flavors and OpenBSD).
2693
Benjamin Peterson14cb6bc2008-08-26 17:08:40 +00002694C-API
2695-----
2696

2714
Nick Coghland2e09382008-09-11 12:11:06 +00002715- Issue #3781: Clean up the API for warnings.catch_warnings() by having it
Brett Cannon672237d2008-09-09 00:49:16 +00002716 return a list or None rather than a custom object.
2717
Benjamin Peterson6ac7d7c2008-09-06 19:28:11 +00002718- Issue #1638033: Cookie.Morsel gained the httponly attribute.

2742 warnings.catch_warnings() along with some API cleanup. Expanding the tests
2743 for catch_warnings() also led to an improvement in the raising of a
2744 DeprecationWarning related to warnings.warn_explicit().
2745
Benjamin Peterson973e6c22008-09-01 23:12:58 +00002746- The deprecation warnings for the old camelCase threading API were removed.

Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00002810What's New in Python 2.6 beta 3?
2811================================
2812
Barry Warsaw07a4a382008-08-21 01:15:08 +00002813*Release date: 20-Aug-2008*
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00002814
2815Core and Builtins
2816-----------------
2817
Guido van Rossumf8402962008-08-20 15:01:50 +00002818- Issue #1878: Remove Py_TPFLAGS_HAVE_VERSION_TAG from
2819 Py_TPFLAGS_DEFAULT when not building the core. This means 3rd party
2820 extensions do not automatically benefit from the class attribute
2821 cache; they will have to explicitly add Py_TPFLAGS_HAVE_VERSION_TAG
2822 to their tp_flags field if they care. This is a backwards
2823 compatibility feature; in 3.0, all types will use the cache by
2824 default.
2825
Benjamin Petersonf647dc12008-08-20 01:27:30 +00002826- Keyword arguments can now follow starred arguments. (``f(a, *args,
2827 keyword=23)`` is now valid syntax.)
2828
Thomas Heller0ad5ae02008-08-19 19:25:04 +00002829- ctypes function pointers that are COM methods have a boolean True
2830 value again.
2831
Martin v. Löwisf91d46a2008-08-12 14:49:50 +00002832- Issue #3139: Make buffer-interface thread-safe wrt. PyArg_ParseTuple,
2833 by denying s# to parse objects that have a releasebuffer procedure,
2834 and introducing s*.
2835
Georg Brandl1e13ea92008-08-11 09:07:59 +00002836- Issue #3537: Fix an assertion failure when an empty but presized dict
2837 object was stored in the freelist.
2838
Mark Dickinsonb6467572008-08-04 21:30:09 +00002839- Issue #1481296: Make long(float('nan')) and int(float('nan')) raise
2840 ValueError consistently across platforms.
2841
Amaury Forgeot d'Arc39fd6722008-07-31 21:28:03 +00002842- Issue #3479: On platforms where sizeof(int) is smaller than sizeof(long)
2843 (64bit Unix, for example), unichr() would truncate its argument and return
2844 u'\x00' for unichr(2**32). Now it properly raises an OverflowError.
2845
Neal Norwitze7d8be82008-07-31 17:17:14 +00002846- Apply security patches from Apple.
2847
Amaury Forgeot d'Arc246daed2008-07-31 00:42:16 +00002848- Issue #2542: Now that issubclass() may call arbitrary code, ensure that
2849 PyErr_ExceptionMatches returns 0 when an exception occurs there.
2850
Antoine Pitrou92f82162008-07-25 22:22:08 +00002851- Issue #1819: function calls with several named parameters are now on
2852 average 35% faster (as measured by pybench).
2853
Amaury Forgeot d'Arce4921fe2008-07-21 22:00:38 +00002854- Issue #2378: An unexpected UnboundLocalError or NameError could appear when
2855 the python debugger steps into a class statement: the free variables (local
2856 variables defined in an outer scope) would be deleted from the outer scope.
2857
Gregory P. Smith0470bab2008-07-22 04:46:32 +00002858- Issue #2620: Overflow checking when allocating or reallocating memory
2859 was not always being done properly in some python types and extension
2860 modules. PyMem_MALLOC, PyMem_REALLOC, PyMem_NEW and PyMem_RESIZE have
2861 all been updated to perform better checks and places in the code that
2862 would previously leak memory on the error path when such an allocation
2863 failed have been fixed.
2864
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00002865Library
2866-------
2867

2869
Benjamin Petersone977ad42008-08-20 01:42:01 +00002870- The methods ``is_in_tuple()``, ``is_vararg()``, and ``is_keywordarg()`` of
2871 symtable.Symbol have been deprecated for removal in 3.0 and the next release.
2872
Amaury Forgeot d'Arc351ffb82008-08-18 19:23:47 +00002873- Issue #2234: distutils failed for some versions of the cygwin compiler. The
2874 version reported by these tools does not necessarily follow the python
2875 version numbering scheme, so the module is less strict when parsing it.
2876
Nick Coghlanf70385a2008-08-18 12:42:46 +00002877- Issue #2235: Added Py3k warnings for types which will become unhashable
2878 under the stricter __hash__ inheritance rules in 3.0. Several types
2879 which did not meet the rules for hash invariants and were already
2880 unhashable in 3.0 have now been explicitly flagged as unhashable in
2881 2.6 as well (collections.Mapping, collections.Set, unittest.TestSuite,
2882 xml.dom.minidom.NamedNodeMap, numbers.Number, UserList.UserList)
2883
Brett Cannon88f801d2008-08-18 00:46:22 +00002884- Update __all__ for cookielib, csv, os, urllib2, and weakref to include things
2885 imported into the module but exposed as part of the module's API.
2886
Brett Cannon7b96f072008-08-18 00:41:11 +00002887- Remove an unneeded import of abc.ABCMeta from 'inspect'.
2888

2892
Hirokazu Yamamoto41a81eb2008-08-17 13:10:46 +00002893- Issue #3575: Incremental decoder's decode function now takes bytearray
2894 by using 's*' instead of 't#'.
2895
Mark Dickinson3e4caeb2009-02-21 20:27:01 +00002896- Issue #2222: Fixed reference leak when occurred os.rename()
Hirokazu Yamamoto7f30a682008-08-17 09:46:56 +00002897 fails unicode conversion on 2nd parameter. (windows only)
2898
Facundo Batista94f243a2008-08-17 03:38:39 +00002899- Issue 2464. urllib2 now supports a malformation in the URL received
2900 in a redirect.
2901
Brett Cannonabe423e2008-08-16 21:47:07 +00002902- Silence the DeprecationWarning raised when importing mimetools in
Brett Cannon721b1452008-08-16 22:00:27 +00002903 BaseHTTPServer, cgi (and rfc822), httplib.
Brett Cannonabe423e2008-08-16 21:47:07 +00002904
Facundo Batistaeb90b782008-08-16 14:44:07 +00002905- Issue #2776: fixed small issue when handling an URL with double slash
2906 after a 302 response in the case of not going through a proxy.
2907
Antoine Pitroub90a8be2008-08-15 21:03:21 +00002908- Issue #2676: in the email package, content-type parsing was hanging on
2909 pathological input because of quadratic or exponential behaviour of a
2910 regular expression.
2911
Antoine Pitrou11ec65d2008-08-14 21:04:30 +00002912- Issue #3476: binary buffered reading through the new "io" library is now
2913 thread-safe.
2914
Brett Cannonbf3157b2008-08-14 05:00:03 +00002915- Silence the DeprecationWarning of rfc822 when it is imported by mimetools
2916 since mimetools itself is deprecated. Because modules are cached, all
2917 subsequent imports of rfc822 will not raise a visible DeprecationWarning.
2918

Antoine Pitroude781a42008-08-09 12:43:23 +00002953 asking for a specific length. This problem only affected files opened

2997
Nick Coghlan2a0c2b12008-08-04 12:47:17 +00002998- Issue #643841: The language reference now provides more detailed

3010-----------------
3011
Georg Brandl3e483f62008-07-16 22:57:41 +00003012- Issue #3156: Fix inconsistent behavior of the bytearray type: all
3013 its methods now allow for items objects that can be converted to
3014 an integer using operator.index().
3015
Mark Dickinson64b7e502008-07-16 09:40:03 +00003016- Issue #3360: Fix incorrect parsing of '020000000000.0', which
3017 produced a ValueError instead of giving the correct float.
3018
Eric Smitha5fa5a22008-07-16 00:11:49 +00003019- Issue #3083: Add alternate (#) formatting for bin, oct, hex output
3020 for str.format(). This adds the prefix 0b, 0o, or 0x, respectively.
3021
Mark Dickinson7103aa42008-07-15 19:08:33 +00003022- Issue #3008: the float type has a new instance method 'float.hex'
3023 and a new class method 'float.fromhex' to convert floating-point
3024 numbers to and from hexadecimal strings, respectively.
3025
Nick Coghlan6d6bd442008-07-15 15:40:22 +00003026- Issue #2235: __hash__ is once again inherited by default. To allow
3027 collections.Hashable to remain meaningful in the presence of the
3028 default hash implementation (object.__hash__), it is now possible
3029 to explicit block inheritance of hash by setting __hash__=None at
3030 the Python level, or tp_hash=PyObject_HashNotImplemented at the C
3031 level.
3032
Nick Coghlanb028f502008-07-13 14:52:36 +00003033- Issue #3221: Issue a RuntimeWarning instead of raising SystemError if
3034 the parent module cannot be found while performing an absolute import.
3035 This means that an incorrectly defined __package__ attribute will
3036 now only prevent relative imports in that module rather than causing
3037 all imports from that module to fail.
3038
Nick Coghlan14ff9942008-07-08 14:21:42 +00003039- Issue #2517: Allow unicode messages in Exceptions again by correctly

3049 another thread's dictionary.
3050
Mark Dickinson1ec2fcd2008-06-20 14:53:43 +00003051- Issue #3004: Minor change to slice.indices(): the start and stop
3052 arguments are now treated identically, making the behaviour easier
3053 to describe and understand. For example, slice(None, -10,
3054 1).indices(9) now returns (0, 0, 1) instead of (0, -1, 1), and
3055 slice(None, 10, -1).indices(10) returns (9, 9, -1) instead of (9,
3056 10, -1).
3057
Georg Brandl278fc502008-07-19 12:46:12 +00003058- Issue #3219: Calling a function with repeated keyword arguments,
3059 f(a=2, a=23), would not cause a syntax error. This was a regression
3060 from 2.4 caused by the switch to the new compiler.

Georg Brandl278fc502008-07-19 12:46:12 +00003062- Issue #2862: Make int and float freelist management consistent with
3063 other freelists. Changes their CompactFreeList apis into

3071 error when they failed.
3072
Martin v. Löwisaabf4042008-08-02 07:20:25 +00003073- Issue #799428: Fix Tkinter.Misc._nametowidget to unwrap Tcl command objects.

Amaury Forgeot d'Arc0f7cddc2008-07-06 21:34:39 +00003098- Issue #839496: SimpleHTTPServer used to open text files in text mode. This is
3099 both unnecessary (HTTP allows text content to be sent in several forms) and
Andrew M. Kuchlingcc3f2b12008-07-10 14:43:31 +00003100 wrong because the actual transmitted size could differ from the
Amaury Forgeot d'Arc0f7cddc2008-07-06 21:34:39 +00003101 content-length. The problem had been corrected in the 2.4 branch, but never

Nick Coghlanc060b0e2008-07-02 13:09:19 +00003117- Issue #3190: Pydoc now hides the automatic module attribute __package__ (the

Benjamin Peterson23681932008-05-12 21:42:13 +00003487
Vinay Sajip9828b7e2008-06-17 11:04:02 +00003488- Library: on MacOS X you can now set ``ARCHFLAGS`` in the shell
Ronald Oussoren5640ce22008-06-05 12:58:24 +00003489 environment to control the '-arch' flags that are used to build
3490 an extension. This was added for compatibility with Apple's build
3491 of Python.
3492
3493- The bundled OSX-specific copy of libbffi is now in sync with the version
3494 shipped with PyObjC 2.0 and includes support for x86_64 and ppc64 platforms.
3495
Georg Brandl25c34082008-08-18 23:09:49 +00003496- The threading module gained aliases for names that will be removed in the
3497 3.x series.

3505
Brett Cannonb61d8012008-05-11 23:39:04 +00003506- ``Lib/lib-old`` is now added to sys.path.
3507
Ronald Oussoren5640ce22008-06-05 12:58:24 +00003508- On MacOS X it is now possible to install the framework in 64-bit
3509 mode or even as a 4-way universal binary (that is, PPC, i386,
Georg Brandl5cc774e2008-06-11 20:28:06 +00003510 PPC64 and x86_64 support in one binary).
Ronald Oussoren5640ce22008-06-05 12:58:24 +00003511
3512 This is controlled by the configure argument ``--with-universal-archs``:
3513
3514 - ``--with-universal-archs=all``: install 4-way universal
3515
3516 - ``--with-universal-archs=32-bit``: install 2-way universal, 32-bit (the default)
3517
3518 - ``--with-universal-archs=64-bit``: install 2-way universal, 64-bit
3519
3520 This option should be used in combination with ``--enable-universalsdk=``.
3521
3522 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 +00003531
3532- The PyString functions have been renamed to PyBytes. A batch of
3533 defines were added so that the linker still sees the original
3534 PyString names.

Georg Brandl3ee81df2008-05-17 18:14:43 +00003572- Issue #1631171: Re-implement the 'warnings' module in C (the
3573 original Python code has been kept as backup). This will allow for
3574 using the 'warning's machinery in such places as the parser where
3575 use of pure Python code is not possible. Both the ``showarning()``
3576 and ``formatwarning()`` gain an optional 'line' argument which is
3577 not called by default for backwards-compatibility reasons. Setting
3578 ``warnings.showwarning()`` to an implementation that lacks support
3579 for the ``line`` argument will raise a DeprecationWarning.

Gregory P. Smithd59fefb2008-04-22 08:11:33 +00003604- The getpass module has been improved on Unix. It now uses /dev/tty
3605 by default and uses stderr instead of stdout. A GetPassWarning is
3606 issued when input echo cannot be controlled.

Georg Brandl3ee81df2008-05-17 18:14:43 +00003621- Issue #2513: distutils on Windows is now capable of cross-compiling
Mark Hammond495cf992008-04-07 01:53:39 +00003622 extension modules between 32 and 64 bit platforms. See the distutls

Georg Brandl3ee81df2008-05-17 18:14:43 +00003642- Issue #2550: The approach used by client/server code for obtaining
3643 ports to listen on in network-oriented tests has been refined in an
3644 effort to facilitate running multiple instances of the entire
3645 regression test suite in parallel without issue.
3646 test_support.bind_port() has been fixed such that it will always
3647 return a unique port -- which wasn't always the case with the
3648 previous implementation, especially if socket options had been set
3649 that affected address reuse (i.e. SO_REUSEADDR, SO_REUSEPORT). The
3650 new implementation of bind_port() will actually raise an exception
3651 if it is passed an AF_INET/SOCK_STREAM socket with either the
3652 SO_REUSEADDR or SO_REUSEPORT socket option set. Furthermore, if
3653 available, bind_port() will set the SO_EXCLUSIVEADDRUSE option on
3654 the socket it's been passed. This currently only applies to
3655 Windows. This option prevents any other sockets from binding to the
3656 host/port we've bound to, thus removing the possibility of the
3657 'non-deterministic' behaviour, as Microsoft puts it, that occurs
3658 when a second SOCK_STREAM socket binds and accepts to a host/port
3659 that's already been bound by another socket. The optional preferred
3660 port parameter to bind_port() has been removed. Under no
3661 circumstances should tests be hard coding ports!
3662
3663 test_support.find_unused_port() has also been introduced, which will
3664 pass a temporary socket object to bind_port() in order to obtain an
3665 unused port. The temporary socket object is then closed and
3666 deleted, and the port is returned. This method should only be used
3667 for obtaining an unused port in order to pass to an external program
3668 (i.e. the -accept [port] argument to openssl's s_server mode) or as
3669 a parameter to a server-oriented class that doesn't give you direct
3670 access to the underlying socket used.
3671
3672 Finally, test_support.HOST has been introduced, which should be used
3673 for the host argument of any relevant socket calls (i.e. bind and
3674 connect).
Trent Nelsone41b0062008-04-08 23:47:30 +00003675
3676 The following tests were updated to following the new conventions:
Georg Brandl3ee81df2008-05-17 18:14:43 +00003677 test_socket, test_smtplib, test_asyncore, test_ssl, test_httplib,
Trent Nelsone41b0062008-04-08 23:47:30 +00003678 test_poplib, test_ftplib, test_telnetlib, test_socketserver,
3679 test_asynchat and test_socket_ssl.
3680
Georg Brandl3ee81df2008-05-17 18:14:43 +00003681 It is now possible for multiple instances of the regression test
3682 suite to run in parallel without issue.

3950
Fred Drakea8ee94b2008-03-01 02:45:07 +00003951- Issue #2051: pyc and pyo files are no longer created with permission
Barry Warsaw52973612008-03-01 02:23:38 +00003952 644. The mode is now inherited from the py file.

Vinay Sajipb7edfc42008-04-02 21:10:23 +00003958- Issue #1881: An internal parser limit has been increased. Also see
Facundo Batistafc2d0102008-02-23 12:01:13 +00003959 issue 215555 for a discussion.
3960
Eric Smitha73fbe72008-02-23 03:09:44 +00003961- Added the future_builtins module, which contains hex() and oct().
3962 These are the PEP 3127 version of these functions, designed to be
3963 compatible with the hex() and oct() builtins from Python 3.0. They
3964 differ slightly in their output formats from the existing, unchanged
3965 Python 2.6 builtins. The expected usage of the future_builtins
3966 module is:
3967 from future_builtins import hex, oct
3968
Eric Smith7ef40bf2008-02-20 23:34:22 +00003969- Issue #1600: Modifed PyOS_ascii_formatd to use at most 2 digit
3970 exponents for exponents with absolute value < 100. Follows C99
3971 standard. This is a change on Windows, which would use 3 digits.
3972 Also, added 'n' to the formats that PyOS_ascii_formatd understands,
3973 so that any alterations it does to the resulting string will be
3974 available in stringlib/formatter.h (for float.__format__).
3975
Eric Smith5a3c1352008-02-19 13:21:56 +00003976- Implemented PEP 3101, Advanced String Formatting. This adds a new
3977 builtin format(); a format() method for str and unicode; a
3978 __format__() method to object, str, unicode, int, long, float, and
3979 datetime; the class string.Formatter; and the C API
3980 PyObject_Format().
3981
Georg Brandl3ee81df2008-05-17 18:14:43 +00003982- Fixed several potential crashes, all caused by specially crafted
3983 __del__ methods exploiting objects in temporarily inconsistent
3984 state.
Amaury Forgeot d'Arc632fad32008-02-16 20:55:24 +00003985
Vinay Sajipb7edfc42008-04-02 21:10:23 +00003986- Issue #2115: Important speedup in setting __slot__ attributes. Also
Georg Brandl3ee81df2008-05-17 18:14:43 +00003987 prevent a possible crash: an Abstract Base Class would try to access
3988 a slot on a registered virtual subclass.
Amaury Forgeot d'Arc60d6c7f2008-02-15 21:22:45 +00003989

3994 in order to allow pymalloc to free more arenas. Python may give back
3995 memory to the OS earlier.
Christian Heimes3b718a72008-02-14 12:47:33 +00003996
Georg Brandl3ee81df2008-05-17 18:14:43 +00003997- Issue #2045: Fix an infinite recursion triggered when printing a
3998 subclass of collections.defaultdict, if its default_factory is set
3999 to a bound method.
Amaury Forgeot d'Arcb01aa432008-02-08 00:56:02 +00004000
Christian Heimesf75dbef2008-02-08 00:11:31 +00004001- Fixed a minor memory leak in dictobject.c. The content of the free
4002 list was not freed on interpreter shutdown.
4003
Georg Brandl21e99f42010-03-07 15:23:59 +00004004- Limit free list of method and built-in function objects to 256
Georg Brandl3ee81df2008-05-17 18:14:43 +00004005 entries each.

Georg Brandl3ee81df2008-05-17 18:14:43 +00004007- Patch #1953: Added ``sys._compact_freelists()`` and the C API
4008 functions ``PyInt_CompactFreeList`` and ``PyFloat_CompactFreeList``
Christian Heimes422051a2008-02-04 18:00:12 +00004009 to compact the internal free lists of pre-allocted ints and floats.
4010
Georg Brandl3ee81df2008-05-17 18:14:43 +00004011- Issue #1983: Fixed return type of fork(), fork1() and forkpty()
4012 calls. Python expected the return type int but the fork familie
4013 returns pi_t.
Christian Heimes951cc0f2008-01-31 23:08:23 +00004014
Georg Brandl3ee81df2008-05-17 18:14:43 +00004015- Issue #1678380: Fix a bug that identifies 0j and -0j when they
4016 appear in the same code unit.
Mark Dickinson105be772008-01-31 22:17:37 +00004017
Georg Brandl3ee81df2008-05-17 18:14:43 +00004018- Issue #2025: Add tuple.count() and tuple.index() methods to comply
4019 with the collections.Sequence API.
Raymond Hettinger5b07ebc2008-02-07 00:54:20 +00004020
Georg Brandl3ee81df2008-05-17 18:14:43 +00004021- Patch #1970 by Antoine Pitrou: Speedup unicode whitespace and
4022 linebreak detection
Christian Heimes4d4f2702008-01-30 11:32:37 +00004023
Georg Brandl3ee81df2008-05-17 18:14:43 +00004024- Added ``PyType_ClearCache()`` and ``sys._clear_type_cache`` to clear
4025 the internal lookup cache for ref leak tests.
Christian Heimes908caac2008-01-27 23:34:59 +00004026
Georg Brandl3ee81df2008-05-17 18:14:43 +00004027- Patch #1473257: generator objects gain a gi_code attribute. This is
4028 the same object as the func_code attribute of the function that
4029 produced the generator.
Georg Brandl0cdf9a32008-01-26 14:14:20 +00004030
Georg Brandl3ee81df2008-05-17 18:14:43 +00004031- Issue #1920: "while 0" statements were completely removed by the
4032 compiler, even in the presence of an "else" clause, which is
4033 supposed to be run when the condition is false. Now the compiler
4034 correctly emits bytecode for the "else" suite.
Amaury Forgeot d'Arc31eaafe2008-01-24 22:59:25 +00004035
Guido van Rossumeead05f2008-01-24 18:21:02 +00004036- A few crashers fixed: weakref_in_del.py (issue #1377858);
4037 loosing_dict_ref.py (issue #1303614, test67.py);
4038 borrowed_ref_[34].py (not in tracker).
4039
Vinay Sajipd7cf32e2008-01-24 12:43:33 +00004040- Issue #1069410: The "can't load dll" message box on Windows is
Christian Heimesb2302ba2008-01-23 17:15:06 +00004041 suppressed while an extension is loaded by calling SetErrorMode in
4042 dynload_win.c. The error is still reported properly.
4043
Georg Brandl3ee81df2008-05-17 18:14:43 +00004044- Issue #1915: Python compiles with --enable-unicode=no again. However
Christian Heimes082c9b02008-01-23 14:20:50 +00004045 several extension methods and modules do not work without unicode
4046 support.
4047
Georg Brandl26543b12008-01-21 18:36:51 +00004048- Issue #1882: when compiling code from a string, encoding cookies in the
4049 second line of code were not always recognized correctly.
4050
Georg Brandl14404b62008-01-19 19:27:05 +00004051- Issue #1679: "0x" was taken as a valid integer literal.
4052
Georg Brandl6caad7d2008-01-26 14:19:22 +00004053- Issue #1865: ``bytes`` as an alias for ``str`` and b"" as an alias "" were
Christian Heimes288e89a2008-01-18 18:24:07 +00004054 added.
4055
Christian Heimesc94e2b52008-01-14 04:13:37 +00004056- sys.float_info / PyFloat_GetInfo: The floating point information
4057 object was converted from a dict to a specialized structseq object.
4058
Georg Brandl3ee81df2008-05-17 18:14:43 +00004059- Patch #1816: Added sys.flags structseq. It exposes the status of
4060 most command line arguments and PYTHON* environment variables.
Christian Heimesf31b69f2008-01-14 03:42:48 +00004061
Georg Brandl3ee81df2008-05-17 18:14:43 +00004062- Objects/structseq.c: Implemented new structseq representation. The
4063 patch makes structseqs (e.g. the return value of os.stat) more
4064 readable.
Christian Heimes9c201962008-01-14 03:33:52 +00004065
Georg Brandl3ee81df2008-05-17 18:14:43 +00004066- Patch #1700288: added a type attribute cache that caches method
4067 accesses, resulting in speedups in heavily object-oriented code.
Amaury Forgeot d'Arce4c270c2008-01-14 00:29:41 +00004068
Neal Norwitz3fc15b82008-01-10 05:42:58 +00004069- Bug #1776: __import__() no longer accepts filenames on any platform.
4070 The first parameter to __import__() must be a valid module name.
Christian Heimes3403f152008-01-09 19:56:33 +00004071
Georg Brandlaed6c662008-01-07 17:25:53 +00004072- Patch #1668: renamed THREADDEBUG envvar to PYTHONTHREADDEBUG.
4073
Georg Brandl3ee81df2008-05-17 18:14:43 +00004074- Patch #602345: Add -B command line option, PYTHONDONTWRITEBYTECODE
4075 envvar and sys.dont_write_bytecode attribute. All these can be set
4076 to forbid Python to attempt to write compiled bytecode files.
Georg Brandl2da0fce2008-01-07 17:09:35 +00004077
Georg Brandl3ee81df2008-05-17 18:14:43 +00004078- Improve some exception messages when Windows fails to load an
4079 extension module. Now we get for example '%1 is not a valid Win32
4080 application' instead of 'error code 193'.
Amaury Forgeot d'Arce0b76952008-01-04 02:04:15 +00004081
Georg Brandl3ee81df2008-05-17 18:14:43 +00004082- Bug #1481296: Fixed long(float('nan')) != 0L.

Georg Brandl3ee81df2008-05-17 18:14:43 +00004084- Issue #1640: Added math.isinf(x), math.isnan(x) and math.copysign(x,
4085 y) functions.
Christian Heimese2ca4242008-01-03 20:23:15 +00004086
Christian Heimes0a8143f2007-12-18 23:22:54 +00004087- Issue #1635: Platform independent creation and representation of NaN
Georg Brandl3ee81df2008-05-17 18:14:43 +00004088 and INF. float("nan"), float("inf") and float("-inf") now work on
4089 every platform with IEEE 754 semantics.
Christian Heimes0a8143f2007-12-18 23:22:54 +00004090
Georg Brandl3ee81df2008-05-17 18:14:43 +00004091- Compiler now generates simpler and faster code for dictionary
4092 literals. The oparg for BUILD_MAP now indicates an estimated
4093 dictionary size. There is a new opcode, STORE_MAP, for adding
4094 entries to the dictionary.
Raymond Hettingerfd7ed402007-12-18 21:24:09 +00004095
Georg Brandl3ee81df2008-05-17 18:14:43 +00004096- Issue #1638: %zd configure test fails on Linux.
Christian Heimesdb3d6cb2007-12-16 21:39:43 +00004097
Georg Brandl3ee81df2008-05-17 18:14:43 +00004098- Issue #1620: New property decorator syntax was modifying the
4099 decorator in place instead of creating a new decorator object.
Christian Heimes90e10e72007-12-14 02:35:23 +00004100
Georg Brandl3ee81df2008-05-17 18:14:43 +00004101- Issue #1538: Avoid copying string in split/rsplit if the split char
4102 is not found.
Skip Montanaro26015492007-12-08 15:33:24 +00004103
Andrew M. Kuchling395fe442007-12-05 13:27:20 +00004104- Issue #1553: An erroneous __length_hint__ can make list() raise a
Christian Heimes7cc1c6f2007-12-05 12:52:34 +00004105 SystemError.
4106
Nick Coghlanef01d822007-12-03 12:55:17 +00004107- PEP 366: Allow explicit relative imports when executing modules
4108 inside packages with the -m switch via a new module level
4109 __package__ attribute.
4110

Amaury Forgeot d'Arcce7d10c2007-11-24 13:44:17 +00004118 attribute of an empty cell object.
4119
Georg Brandl3ee81df2008-05-17 18:14:43 +00004120- Issue #1460: The utf-7 incremental decoder did not accept truncated
4121 input. It now correctly saves its state between chunks of data.
Amaury Forgeot d'Arcf57375a2007-11-21 01:38:26 +00004122
Georg Brandl3ee81df2008-05-17 18:14:43 +00004123- Patch #1739468: Directories and zipfiles containing a __main__.py
4124 file can now be directly executed by passing their name to the
4125 interpreter. The directory/zipfile is automatically inserted as the
4126 first entry in sys.path.
Nick Coghlan327a39b2007-11-18 11:56:28 +00004127
Georg Brandl3ee81df2008-05-17 18:14:43 +00004128- Issue #1265: Fix a problem with sys.settrace, if the tracing
4129 function uses a generator expression when at the same time the
4130 executed code is closing a paused generator.
Amaury Forgeot d'Arc0d75f092007-11-13 21:54:28 +00004131
Raymond Hettinger1760c8a2007-11-08 02:52:43 +00004132- sets and frozensets now have an isdisjoint() method.
4133
Raymond Hettinger3f8caa32007-10-24 01:28:33 +00004134- optimize the performance of builtin.sum().
4135
Neal Norwitz44f326e2007-10-05 05:29:17 +00004136- Fix warnings found by the new version of the Coverity checker.
4137
Georg Brandl21e99f42010-03-07 15:23:59 +00004138- The enumerate() built-in function is no longer bounded to sequences
Georg Brandl3ee81df2008-05-17 18:14:43 +00004139 smaller than LONG_MAX. Formerly, it raised an OverflowError. Now,
4140 automatically shifts from ints to longs.
Raymond Hettinger8f669372007-10-03 21:18:11 +00004141
Georg Brandl3ee81df2008-05-17 18:14:43 +00004142- Issue #1686386: Tuple's tp_repr did not take into account the
4143 possibility of having a self-referential tuple, which is possible
4144 from C code. Nor did object's tp_str consider that a type's tp_str
4145 could do something that could lead to an inifinite recursion.
4146 Py_ReprEnter() and Py_EnterRecursiveCall(), respectively, fixed the
4147 issues.
Brett Cannon0b14f242007-09-30 19:45:10 +00004148
Georg Brandl3ee81df2008-05-17 18:14:43 +00004149- Issue #1164: It was possible to trigger deadlock when using the
4150 'print' statement to write to a file since the GIL was not released
4151 as needed. Now PyObject_Print() does the right thing along with
4152 various tp_print implementations of the built-in types and those in
4153 the collections module.
Brett Cannon01531592007-09-17 03:28:34 +00004154
Georg Brandl3ee81df2008-05-17 18:14:43 +00004155- Issue #1147: Exceptions were directly allowing string exceptions in
4156 their throw() method even though string exceptions no longer
4157 allowed.
Brett Cannon4c20bc42007-09-11 21:02:28 +00004158
Georg Brandl3ee81df2008-05-17 18:14:43 +00004159- Issue #1096: Prevent a segfault from getting the repr of a very
4160 deeply nested list by using the recursion counter.
Brett Cannona0c05512007-09-10 21:38:27 +00004161
Brett Cannon1e534b52007-09-07 04:18:30 +00004162- Issue #1202533: Fix infinite recursion calls triggered by calls to
Georg Brandl3ee81df2008-05-17 18:14:43 +00004163 PyObject_Call() never calling back out to Python code to trigger
4164 recursion depth updates/checks. Required the creation of a static
4165 RuntimeError instance in case normalizing an exception put the
4166 recursion check value past its limit. Fixes crashers
4167 infinite_rec_(1|2|4|5).py.
Brett Cannon1e534b52007-09-07 04:18:30 +00004168
Georg Brandl3ee81df2008-05-17 18:14:43 +00004169- Patch #1031213: Decode source line in SyntaxErrors back to its

4173 with %G.
4174
Georg Brandl3ee81df2008-05-17 18:14:43 +00004175- Prevent expandtabs() on string and unicode objects from causing a
4176 segfault when a large width is passed on 32-bit platforms.

Neal Norwitz0ac60192007-05-27 04:08:54 +00004182- Add new attribute names for function objects. All the func_* become
Georg Brandl3ee81df2008-05-17 18:14:43 +00004183 __*__ attributes. (Some already existed, e.g., __doc__ and
4184 __name__.)
Neal Norwitz0ac60192007-05-27 04:08:54 +00004185
Neal Norwitz8b2bfbc2007-05-23 06:35:32 +00004186- Add -3 option to the interpreter to warn about features that are
4187 deprecated and will be changed/removed in Python 3.0.
4188
Georg Brandl2134e752007-05-21 20:34:16 +00004189- Patch #1686487: you can now pass any mapping after '**' in function
4190 calls.
4191
Collin Winter62903052007-05-18 23:11:24 +00004192- except clauses may now be spelled either "except E, target:" or
Georg Brandl3ee81df2008-05-17 18:14:43 +00004193 "except E as target:". This is to provide forwards compatibility
4194 with Python 3.0.
Collin Winter62903052007-05-18 23:11:24 +00004195
Brett Cannon229cee22007-05-05 01:34:02 +00004196- Deprecate BaseException.message as per PEP 352.
4197
Georg Brandl3ee81df2008-05-17 18:14:43 +00004198- Issue #1303614: don't expose object's __dict__ when the dict is
Georg Brandl21e99f42010-03-07 15:23:59 +00004199 inherited from a built-in base.
Armin Rigo9790a272007-05-02 19:23:31 +00004200
Vinay Sajip8549ce32007-05-06 17:53:37 +00004201- When __slots__ are set to a unicode string, make it work the same as
Neal Norwitzcbd9ee62007-04-14 05:25:50 +00004202 setting a plain string, ie don't expand to single letter identifiers.
4203
Raymond Hettinger13936692007-04-11 18:40:58 +00004204- Request #1191699: Slices can now be pickled.
4205
Raymond Hettinger4db5fe92007-04-12 04:10:00 +00004206- Request #1193128: str.translate() now allows a None argument for
4207 translations that only remove characters without re-mapping the
4208 remaining characters.
4209
Georg Brandl5cb76c12007-03-21 09:00:39 +00004210- Patch #1682205: a TypeError while unpacking an iterable is no longer
4211 masked by a generic one with the message "unpack non-sequence".
4212
Neal Norwitzaa754b72007-03-21 06:39:48 +00004213- Remove unused file Python/fmod.c.
4214
Guido van Rossum143b5642007-03-23 04:58:42 +00004215- Bug #1683368: The object.__init__() and object.__new__() methods are
4216 now stricter in rejecting excess arguments. The only time when
4217 either allows excess arguments is when it is not overridden and the
4218 other one is. For backwards compatibility, when both are
4219 overridden, it is a deprecation warning (for now; maybe a Py3k
Guido van Rossum234b1ff2007-03-23 19:39:01 +00004220 warning later). Also, type.__init__() insists on the same signature
4221 as supported by type.__new__().
Guido van Rossum143b5642007-03-23 04:58:42 +00004222
Georg Brandl3ee81df2008-05-17 18:14:43 +00004223- Patch #1675423: PyComplex_AsCComplex() now tries to convert an
4224 object to complex using its __complex__() method before falling back
4225 to the __float__() method. Therefore, the functions in the cmath
4226 module now can operate on objects that define a __complex__()
4227 method.
Georg Brandl2b869942007-03-17 16:08:45 +00004228
Georg Brandl3ee81df2008-05-17 18:14:43 +00004229- Patch #1623563: allow __class__ assignment for classes with
4230 __slots__. The old and the new class are still required to have the
4231 same slot names.
Žiga Seilnacht6f2d09c2007-03-16 11:59:38 +00004232

4238 its type.
Žiga Seilnacht20f43d32007-03-15 11:44:55 +00004239
Georg Brandl3ee81df2008-05-17 18:14:43 +00004240- Patch #1680015: Don't modify __slots__ tuple if it contains an

4247
Georg Brandl871f1bc2007-03-12 13:17:36 +00004248- The dir() function has been extended to call the __dir__() method on
Georg Brandl3ee81df2008-05-17 18:14:43 +00004249 its argument, if it exists. If not, it will work like before. This
4250 allows customizing the output of dir() in the presence of a
4251 __getattr__().

Georg Brandlaa2321b2007-03-07 00:40:28 +00004263- Patch #703779: unset __file__ in __main__ after running a file. This

4334 embedded in the string to convert.
4335
Georg Brandl846f73a2006-10-08 07:11:54 +00004336- Bug #1569998: break inside a try statement (outside a loop) is now

Georg Brandl4e933132006-09-06 20:05:58 +00004366- Bug #1542051: Exceptions now correctly call PyObject_GC_UnTrack.

Guido van Rossum8bc09652008-02-21 18:18:37 +00004425- Removed uses of dict.has_key() from distutils, and uses of

Georg Brandl3ee81df2008-05-17 18:14:43 +00004775 the client's request was successfully received, understood, and

Georg Brandl3ee81df2008-05-17 18:14:43 +00004816 AttributeError instead of an IOError when the server's response
4817 didn't contain a valid HTTP status line.

Georg Brandl3ee81df2008-05-17 18:14:43 +00005301 time so that opening a database previously created with the DB_DUP
5302 or DB_DUPSORT flag set will keep the proper behavior on subsequent
5303 opens. Specifically: dictionary assignment to a DB object will
5304 replace all values for a given key when the database allows
5305 duplicate values. DB users should use DB.put(k, v) when they want
5306 to store duplicates; not DB[k] = v.

5313 characters with ASCII value less than 32. Also, it correctly quotes
5314 dots only if they occur on a single line, as opposed to the previous
5315 behavior of quoting dots if they are the second character of any
5316 line.
