56Core and Builtins
57-----------------
58
Philip Jenveyaebbaeb2010-04-06 23:24:45 +000059- Issue #7301: Add environment variable $PYTHONWARNINGS.
60
Benjamin Peterson3a1dfa22010-04-06 21:50:00 +000061- Issue #8329: Don't return the same lists from select.select when no fds are
62 changed.
63
Mark Dickinson82791672010-04-06 16:47:55 +000064- Issue #8259: 1L << (2**31) no longer produces an 'outrageous shift error'
65 on 64-bit machines. The shift count for either left or right shift is
66 permitted to be up to sys.maxsize.
67
Benjamin Peterson4ceeeb02010-04-03 22:48:51 +000068- Ensure that tokenization of identifiers is not affected by locale.
69
Tarek Ziadé00002952010-04-03 08:37:59 +000070- Issue #1222585: Added LDCXXSHARED for C++ support. Patch by Arfrever.

73
Eric Smithd44b2fc2010-04-02 12:30:56 +000074- Issue #7994: Issue a PendingDeprecationWarning if object.__format__
75 is called with a non-empty format string. This is an effort to
76 future-proof user code. If a derived class does not currently
77 implement __format__ but later adds its own __format__, it would
78 most likely break user code that had supplied a format string. This
79 will be changed to a DeprecationWaring in Python 3.3 and it will be
80 an error in Python 3.4.
81
Antoine Pitroua57df2c2010-03-31 21:32:15 +000082- Issue #8268: Old-style classes (not just instances) now support weak
83 references.

Georg Brandlba83f822010-03-14 09:50:54 +000096 (SIGINT). If an error occurs while importing the site module, the error is
97 printed and Python exits. Initialize the GIL before importing the site
Victor Stinner66644262010-03-10 22:30:19 +000098 module.

108 using the new attributes `ssl.OPENSSL_VERSION`, `ssl.OPENSSL_VERSION_INFO`
109 and `ssl.OPENSSL_VERSION_NUMBER`.
110
Benjamin Peterson76a23c12010-04-04 23:23:22 +0000111- Issue #8310: Allow dis to examine new style classes.
112
Mark Dickinson8a950712010-04-03 15:47:46 +0000113- Issue #8257: The Decimal construct now accepts a float instance
114 directly, converting that float to a Decimal of equal value:

Raymond Hettinger34c35b22010-04-03 10:22:00 +0000119- collections.Counter() now supports a subtract() method.
120
Raymond Hettingera551f312010-04-04 18:34:45 +0000121- the functools module now has a total_ordering() class decorator
Georg Brandl4fabac52010-04-14 08:53:38 +0000122 to simplify the specification of rich comparisons.
Raymond Hettingera551f312010-04-04 18:34:45 +0000123
Raymond Hettingerbb006cf2010-04-04 21:45:01 +0000124- The functools module also adds cmp_to_key() as a tool to transition
Raymond Hettingera551f312010-04-04 18:34:45 +0000125 old-style comparison functions to new-style key-functions.
126
Mark Dickinson7c63eee2010-04-02 22:27:36 +0000127- Issue #8294: The Fraction constructor now accepts Decimal and float
128 instances directly.

Mark Dickinsone096e822010-04-02 10:17:07 +0000130- Issue #7279: Comparisons involving a Decimal signaling NaN now
131 signal InvalidOperation instead of returning False. (Comparisons
Mark Dickinsonf3eeca12010-04-02 10:35:12 +0000132 involving a quiet NaN are unchanged.) Also, Decimal quiet NaNs
133 are now hashable; Decimal signaling NaNs remain unhashable.
Mark Dickinsone096e822010-04-02 10:17:07 +0000134
Mark Dickinson99d80962010-04-02 08:53:22 +0000135- Issue #2531: Comparison operations between floats and Decimal
136 instances now return a result based on the numeric values of the
137 operands; previously they returned an arbitrary result based on
138 the relative ordering of id(float) and id(Decimal).
139
Barry Warsawf7f2d6f2010-03-31 21:07:16 +0000140- Issue #8233: When run as a script, py_compile.py optionally takes a single
141 argument `-` which tells it to read files to compile from stdin. Each line
142 is read on demand and the named file is compiled immediately. (Original
143 patch by Piotr Ożarowski).
144
145- Issue #3135: Add inspect.getcallargs, which binds arguments to a function
146 like a normal call.
Benjamin Peterson7e213252010-03-30 17:58:13 +0000147
Florent Xicluna58b65662010-03-30 16:29:03 +0000148- Backwards incompatible change: Unicode codepoints line tabulation (0x0B) and
149 form feed (0x0C) are now considered linebreaks, as specified in Unicode
150 Standard Annex #14. See issue #7643.

152
Mark Dickinson9588d992010-03-27 11:14:37 +0000153- Comparisons using one of <, <=, >, >= between a complex instance and
154 a Fractions instance now raise TypeError instead of returning
155 True/False. This makes Fraction <=> complex comparisons consistent with
156 int <=> complex, float <=> complex, and complex <=> complex comparisons.
157
Michael Foorde6410c52010-03-29 20:04:23 +0000158- Addition of ``WeakSet`` to the ``weakref`` module.

169 now silenced.
170
Florent Xicluna9e7a4c92010-03-22 16:07:38 +0000171- Issue #7703: ctypes supports both buffer() and memoryview(). The former is

176
Vinay Sajip804899b2010-03-22 15:29:01 +0000177- logging: Added getChild utility method to Logger and added isEnabledFor
178 method to LoggerAdapter.
179
Vinay Sajip31e928e2010-03-22 13:02:28 +0000180- Issue #8201: logging: Handle situation of non-ASCII and Unicode
181 logger names existing at the same time, causing a Unicode error
182 when configuration code attempted to sort the existing loggers.
183
Vinay Sajip3017a7b2010-03-22 12:33:08 +0000184- Issue #8200: logging: Handle errors when multiprocessing is not

188 Also, enable the SSL_MODE_AUTO_RETRY flag on SSL sockets, so that blocking
189 reads and writes are always retried by OpenSSL itself.
Antoine Pitrou448da712010-03-21 19:33:38 +0000190

Georg Brandlba83f822010-03-14 09:50:54 +0000212 for ``TimedRotatingFileHandler`` by using the modification time of an
213 existing log file to compute the next rollover time. If the log file does
214 not exist, the current time is used as the basis for the computation.
Vinay Sajip9098ee42010-03-12 06:01:21 +0000215

Georg Brandlba83f822010-03-14 09:50:54 +0000224- Issue #7143: email: ``get_payload()`` used to strip any trailing newline from
225 a base64 transfer-encoded payload *after* decoding it; it no longer does.
226 This is a behavior change, so email's minor version number is now bumped, to

Mark Dickinson4846a8e2010-04-03 14:05:10 +0000253- Issue #8300: When passing a non-integer argument to struct.pack with any
254 integer format code, struct.pack first attempts to convert the non-integer
255 using its __index__ method. If that method is non-existent or raises
256 TypeError it goes on to try the __int__ method, as described below.
257
Georg Brandlba83f822010-03-14 09:50:54 +0000258- Issue #1530559: When passing a non-integer argument to struct.pack with *any*
259 integer format code (one of 'bBhHiIlLqQ'), struct.pack attempts to use the
260 argument's __int__ method to convert to an integer before packing. It also
261 produces a DeprecationWarning in this case. (In Python 2.6, the behaviour
262 was inconsistent: __int__ was used for some integer codes but not for others,
263 and the set of integer codes for which it was used differed between native
264 packing and standard packing.)

Georg Brandlba83f822010-03-14 09:50:54 +0000562 file position when calling `truncate()`. It would previously change the file
563 position to the given argument, which goes against the tradition of
Antoine Pitrouf3fa0742010-01-31 22:26:04 +0000564 ftruncate() and other truncation APIs. Patch by Pascal Chambon.

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

660Core and Builtins
661-----------------
662
Georg Brandlba83f822010-03-14 09:50:54 +0000663- The ``__complex__()`` method is now looked up on the class of instances to
664 make it consistent with other special methods.

Antoine Pitrou5b7139a2010-01-02 21:12:58 +0000666- Issue #7462: Implement the stringlib fast search algorithm for the `rfind`,
667 `rindex`, `rsplit` and `rpartition` methods. Patch by Florent Xicluna.
668
Mark Dickinson1b34d252010-01-01 17:27:30 +0000669- Issue #5080: A number of functions and methods previously produced a
Georg Brandlba83f822010-03-14 09:50:54 +0000670 DeprecationWarning when passed a float argument where an integer was expected.
671 These functions and methods now raise TypeError instead. The majority of the
672 effects of this change are in the extension modules, but some core functions
673 and methods are affected: notably the 'chr', 'range' and 'xrange' builtins,
674 and many unicode/str methods.

686
Georg Brandlba83f822010-03-14 09:50:54 +0000687- Issue #1811: Improve accuracy and cross-platform consistency for true division
688 of integers: the result of a/b is now correctly rounded for ints a and b (at
689 least on IEEE 754 platforms), and in particular does not depend on the
690 internal representation of a long.

698
Georg Brandlba83f822010-03-14 09:50:54 +0000699 These executables now work properly with the arch(1) command: ``arch -ppc
700 python`` will start a universal binary version of python in PPC mode (unlike
701 previous releases).

841 to 'g' for large values.

Georg Brandlba83f822010-03-14 09:50:54 +0000857- Issue #7117: ``repr(x)`` for a float x returns a result based on the shortest
858 decimal string that's guaranteed to round back to x under correct rounding
859 (with round-half-to-even rounding mode). Previously it gave a string based on
860 rounding x to 17 decimal digits. repr(x) for a complex number behaves
861 similarly. On platforms where the correctly-rounded strtod and dtoa code is
862 not supported (see below), repr is unchanged.
Mark Dickinsonb678de82009-11-19 18:41:49 +0000863
Georg Brandlba83f822010-03-14 09:50:54 +0000864- Issue #7117: On almost all platforms: float-to-string and string-to-float
865 conversions within Python are now correctly rounded. Places these conversions
866 occur include: str for floats and complex numbers; the float and complex
867 constructors; old-style and new-style numeric formatting; serialization and
868 deserialization of floats and complex numbers using marshal, pickle and json;
869 parsing of float and imaginary literals in Python code; Decimal-to-float
870 conversion.
Mark Dickinsonb678de82009-11-19 18:41:49 +0000871
Georg Brandlba83f822010-03-14 09:50:54 +0000872 The conversions use a Python-adapted version of David Gay's well-known dtoa.c,
873 providing correctly-rounded strtod and dtoa C functions. This code is
874 supported on Windows, and on Unix-like platforms using gcc, icc or suncc as
875 the C compiler. There may be a small number of platforms on which correct
876 operation of this code cannot be guaranteed, so the code is not used: notably,
877 this applies to platforms where the C double format is not IEEE 754 binary64,
878 and to platforms on x86 hardware where the x87 FPU is set to 64-bit precision
879 and Python's configure script is unable to determine how to change the FPU
880 precision. On these platforms conversions use the platform strtod and dtoa,
881 as before.

Georg Brandlba83f822010-03-14 09:50:54 +0000883- Issue #7117: Backport round implementation from Python 3.x. ``round()`` now
884 uses the correctly-rounded string <-> float conversions described above (when
885 available), and so produces correctly rounded results that will display nicely
886 under the float repr. There are two related small changes: (1) round now
887 accepts any class with an ``__index__()`` method for its second argument (but
888 no longer accepts floats for the second argument), and (2) an excessively
889 large second integer argument (e.g., ``round(1.234, 10**100)``) no longer
890 raises an exception.

Mark Dickinsonb1d45852009-05-11 15:33:08 +00001032
Georg Brandlba83f822010-03-14 09:50:54 +00001033 (1) inf and nan strings with trailing whitespace were incorrectly rejected;
1034 (2) parsing of strings representing infinities and nans was locale aware; and
1035 (3) the interpretation of fromhex('-nan') didn't match that of float('-nan').

Georg Brandlba83f822010-03-14 09:50:54 +00001037- Issue #5920: For ``float.__format__()``, change the behavior with the empty
1038 presentation type (that is, not one of 'e', 'f', 'g', or 'n') to be like 'g'
1039 but with at least one decimal point and with a default precision
1040 of 12. Previously, the behavior the same but with a default precision of 6.
1041 This more closely matches ``str()``, and reduces surprises when adding
1042 alignment flags to the empty presentation type. This also affects the new
1043 complex.__format__ in the same way.
1044
1045- Issue #5890: In subclasses of 'property' the __doc__ attribute was shadowed by

1117 internal representation of integers, for performance reasons. Base 2**30 is
1118 enabled by default on 64-bit machines. Add --enable-big-digits option to

2473 __long__ method could be packed by 'q', 'Q', '*q', '*Q'; for x with
2474 neither __int__ nor __long__, TypeError used to be raised (with a
2475 confusing error message) for 'I', 'L', '*B', '*H', '*I', '*L', and
2476 struct.error in other cases.

Georg Brandlba83f822010-03-14 09:50:54 +00002529 leak-chasing test runs give sensible results. The previous method of reaping
2530 threads could return successfully while some Thread objects were still

Antoine Pitrou3c9f5412008-09-13 20:30:30 +00002652 AttributeError instead of RuntimeError, depending in which C API call
2653 exactly the recursion limit is exceeded. Consequently, both exception types

Martin v. Löwis9fa5a282008-09-11 06:53:30 +00002671- Issue #3642: Suppress warning in obmalloc when size_t is larger than uint.
2672
Amaury Forgeot d'Arc05e34492008-09-10 22:04:45 +00002673- Issue #3743: In a few places, PY_FORMAT_SIZE_T was incorrectly used with
2674 PyString_FromFormat or PyErr_Format to display size_t values. The macro
2675 PY_FORMAT_SIZE_T is designed to select the correct format for the OS
2676 ``printf`` function, whereas PyString_FromFormat has an independent
2677 implementation and uses "%zd" on all platforms for size_t values.
2678 This makes a difference on win64, where ``printf`` needs "%Id" to display
2679 64bit values.
2680
Benjamin Peterson97179b02008-09-09 20:55:01 +00002681- Issue #3634: _weakref.ref(Exception).__init__() gave invalid return value on
2682 error.
2683
Amaury Forgeot d'Arcd3ffb892008-09-09 07:24:30 +00002684- Issue #3777: long() applied to a float object now always return a long
2685 object; previously an int would be returned for small values. the __long__
2686 method is allowed to return either an int or a long, but the behaviour of
2687 float objects should not change to respect backward compatibility.
2688
Amaury Forgeot d'Arc3571fbf2008-09-01 19:52:00 +00002689- Issue #3751: str.rpartition would perform a left-partition when called with
2690 a unicode argument.
2691
Benjamin Peterson17f03ca2008-09-01 14:18:30 +00002692- Issue #3683: Fix compilation when --without-threads is given.
2693
Antoine Pitroud4ae97b2008-08-29 18:39:48 +00002694- Issue #3668: Fix a memory leak with the "s*" argument parser in
Vinay Sajip35e3b032008-09-01 14:33:59 +00002695 PyArg_ParseTuple and friends, which occurred when the argument for "s*"
Antoine Pitroud4ae97b2008-08-29 18:39:48 +00002696 was correctly parsed but parsing of subsequent arguments failed.
2697
Vinay Sajip35e3b032008-09-01 14:33:59 +00002698- Issue #2534: speed up isinstance() and issubclass() by 50-70%, so as to
Antoine Pitrou0668c622008-08-26 22:42:08 +00002699 match Python 2.5 speed despite the __instancecheck__ / __subclasscheck__
2700 mechanism. In the process, fix a bug where isinstance() and issubclass(),
2701 when given a tuple of classes as second argument, were looking up
2702 __instancecheck__ / __subclasscheck__ on the tuple rather than on each
2703 type object.
2704
Neal Norwitz18aa3882008-08-24 05:04:52 +00002705- Fix crashes on memory allocation failure found with failmalloc.
2706
2707- Fix memory leaks found with valgrind and update suppressions file.
2708
2709- Fix compiler warnings in opt mode which would lead to invalid memory reads.
2710
2711- Fix problem using wrong name in decimal module reported by pychecker.
2712
Christian Heimes7d4c3172008-08-22 19:47:25 +00002713- Silenced another compiler warning about a used but not defined
2714 function 'stringlib_contains_obj'.

Gregory P. Smith2bb25cc2008-09-02 05:29:51 +00002719- Issue #3678: Correctly pass LDFLAGS and LDLAST to the linker on shared
2720 library targets in the Makefile.
2721
Gregory P. Smith980b99b2008-09-07 05:15:18 +00002722- Issue #1204: The configure script now tests for additional libraries
2723 that may be required when linking against readline. This fixes issues
2724 with x86_64 builds on some platforms (a few Linux flavors and OpenBSD).

2746
Nick Coghland2e09382008-09-11 12:11:06 +00002747- Issue #3781: Clean up the API for warnings.catch_warnings() by having it
Brett Cannon672237d2008-09-09 00:49:16 +00002748 return a list or None rather than a custom object.
2749
Benjamin Peterson6ac7d7c2008-09-06 19:28:11 +00002750- Issue #1638033: Cookie.Morsel gained the httponly attribute.

2774 warnings.catch_warnings() along with some API cleanup. Expanding the tests
2775 for catch_warnings() also led to an improvement in the raising of a
2776 DeprecationWarning related to warnings.warn_explicit().
2777
Benjamin Peterson973e6c22008-09-01 23:12:58 +00002778- The deprecation warnings for the old camelCase threading API were removed.

2848-----------------
2849
Guido van Rossumf8402962008-08-20 15:01:50 +00002850- Issue #1878: Remove Py_TPFLAGS_HAVE_VERSION_TAG from
2851 Py_TPFLAGS_DEFAULT when not building the core. This means 3rd party
2852 extensions do not automatically benefit from the class attribute
2853 cache; they will have to explicitly add Py_TPFLAGS_HAVE_VERSION_TAG
2854 to their tp_flags field if they care. This is a backwards
2855 compatibility feature; in 3.0, all types will use the cache by
2856 default.
2857
Benjamin Petersonf647dc12008-08-20 01:27:30 +00002858- Keyword arguments can now follow starred arguments. (``f(a, *args,
2859 keyword=23)`` is now valid syntax.)
2860
Thomas Heller0ad5ae02008-08-19 19:25:04 +00002861- ctypes function pointers that are COM methods have a boolean True
2862 value again.
2863
Martin v. Löwisf91d46a2008-08-12 14:49:50 +00002864- Issue #3139: Make buffer-interface thread-safe wrt. PyArg_ParseTuple,
2865 by denying s# to parse objects that have a releasebuffer procedure,
2866 and introducing s*.
2867
Georg Brandl1e13ea92008-08-11 09:07:59 +00002868- Issue #3537: Fix an assertion failure when an empty but presized dict
2869 object was stored in the freelist.
2870
Mark Dickinsonb6467572008-08-04 21:30:09 +00002871- Issue #1481296: Make long(float('nan')) and int(float('nan')) raise
2872 ValueError consistently across platforms.
2873
Amaury Forgeot d'Arc39fd6722008-07-31 21:28:03 +00002874- Issue #3479: On platforms where sizeof(int) is smaller than sizeof(long)
2875 (64bit Unix, for example), unichr() would truncate its argument and return
2876 u'\x00' for unichr(2**32). Now it properly raises an OverflowError.
2877
Neal Norwitze7d8be82008-07-31 17:17:14 +00002878- Apply security patches from Apple.
2879
Amaury Forgeot d'Arc246daed2008-07-31 00:42:16 +00002880- Issue #2542: Now that issubclass() may call arbitrary code, ensure that
2881 PyErr_ExceptionMatches returns 0 when an exception occurs there.
2882
Antoine Pitrou92f82162008-07-25 22:22:08 +00002883- Issue #1819: function calls with several named parameters are now on
2884 average 35% faster (as measured by pybench).
2885
Amaury Forgeot d'Arce4921fe2008-07-21 22:00:38 +00002886- Issue #2378: An unexpected UnboundLocalError or NameError could appear when
2887 the python debugger steps into a class statement: the free variables (local
2888 variables defined in an outer scope) would be deleted from the outer scope.
2889
Gregory P. Smith0470bab2008-07-22 04:46:32 +00002890- Issue #2620: Overflow checking when allocating or reallocating memory
2891 was not always being done properly in some python types and extension
2892 modules. PyMem_MALLOC, PyMem_REALLOC, PyMem_NEW and PyMem_RESIZE have
2893 all been updated to perform better checks and places in the code that
2894 would previously leak memory on the error path when such an allocation
2895 failed have been fixed.

Hirokazu Yamamoto838c79f2008-08-20 13:14:07 +00002900- Issue #3612: Added some missing basic types in ctypes.wintypes.
2901
Benjamin Petersone977ad42008-08-20 01:42:01 +00002902- The methods ``is_in_tuple()``, ``is_vararg()``, and ``is_keywordarg()`` of
2903 symtable.Symbol have been deprecated for removal in 3.0 and the next release.
2904
Amaury Forgeot d'Arc351ffb82008-08-18 19:23:47 +00002905- Issue #2234: distutils failed for some versions of the cygwin compiler. The
2906 version reported by these tools does not necessarily follow the python
2907 version numbering scheme, so the module is less strict when parsing it.
2908
Nick Coghlanf70385a2008-08-18 12:42:46 +00002909- Issue #2235: Added Py3k warnings for types which will become unhashable
2910 under the stricter __hash__ inheritance rules in 3.0. Several types
2911 which did not meet the rules for hash invariants and were already
2912 unhashable in 3.0 have now been explicitly flagged as unhashable in
2913 2.6 as well (collections.Mapping, collections.Set, unittest.TestSuite,
2914 xml.dom.minidom.NamedNodeMap, numbers.Number, UserList.UserList)
2915
Brett Cannon88f801d2008-08-18 00:46:22 +00002916- Update __all__ for cookielib, csv, os, urllib2, and weakref to include things
2917 imported into the module but exposed as part of the module's API.
2918
Brett Cannon7b96f072008-08-18 00:41:11 +00002919- Remove an unneeded import of abc.ABCMeta from 'inspect'.
2920

3042-----------------
3043
Georg Brandl3e483f62008-07-16 22:57:41 +00003044- Issue #3156: Fix inconsistent behavior of the bytearray type: all
3045 its methods now allow for items objects that can be converted to
3046 an integer using operator.index().
3047
Mark Dickinson64b7e502008-07-16 09:40:03 +00003048- Issue #3360: Fix incorrect parsing of '020000000000.0', which
3049 produced a ValueError instead of giving the correct float.
3050
Eric Smitha5fa5a22008-07-16 00:11:49 +00003051- Issue #3083: Add alternate (#) formatting for bin, oct, hex output
3052 for str.format(). This adds the prefix 0b, 0o, or 0x, respectively.
3053
Mark Dickinson7103aa42008-07-15 19:08:33 +00003054- Issue #3008: the float type has a new instance method 'float.hex'
3055 and a new class method 'float.fromhex' to convert floating-point
3056 numbers to and from hexadecimal strings, respectively.
3057
Nick Coghlan6d6bd442008-07-15 15:40:22 +00003058- Issue #2235: __hash__ is once again inherited by default. To allow
3059 collections.Hashable to remain meaningful in the presence of the
3060 default hash implementation (object.__hash__), it is now possible
3061 to explicit block inheritance of hash by setting __hash__=None at
3062 the Python level, or tp_hash=PyObject_HashNotImplemented at the C
3063 level.
3064
Nick Coghlanb028f502008-07-13 14:52:36 +00003065- Issue #3221: Issue a RuntimeWarning instead of raising SystemError if
3066 the parent module cannot be found while performing an absolute import.
3067 This means that an incorrectly defined __package__ attribute will
3068 now only prevent relative imports in that module rather than causing
3069 all imports from that module to fail.
3070
Nick Coghlan14ff9942008-07-08 14:21:42 +00003071- Issue #2517: Allow unicode messages in Exceptions again by correctly

Amaury Forgeot d'Arc1f40c8a2008-06-30 22:42:40 +00003079- Issue #3088: Corrected a race condition in classes derived from
3080 threading.local: the first member set by a thread could be saved in
3081 another thread's dictionary.
3082
Mark Dickinson1ec2fcd2008-06-20 14:53:43 +00003083- Issue #3004: Minor change to slice.indices(): the start and stop
3084 arguments are now treated identically, making the behaviour easier
3085 to describe and understand. For example, slice(None, -10,
3086 1).indices(9) now returns (0, 0, 1) instead of (0, -1, 1), and
3087 slice(None, 10, -1).indices(10) returns (9, 9, -1) instead of (9,
3088 10, -1).
3089
Georg Brandl278fc502008-07-19 12:46:12 +00003090- Issue #3219: Calling a function with repeated keyword arguments,
3091 f(a=2, a=23), would not cause a syntax error. This was a regression
3092 from 2.4 caused by the switch to the new compiler.

Georg Brandl278fc502008-07-19 12:46:12 +00003094- Issue #2862: Make int and float freelist management consistent with
3095 other freelists. Changes their CompactFreeList apis into

Amaury Forgeot d'Arc0f7cddc2008-07-06 21:34:39 +00003130- Issue #839496: SimpleHTTPServer used to open text files in text mode. This is
3131 both unnecessary (HTTP allows text content to be sent in several forms) and
Andrew M. Kuchlingcc3f2b12008-07-10 14:43:31 +00003132 wrong because the actual transmitted size could differ from the
Amaury Forgeot d'Arc0f7cddc2008-07-06 21:34:39 +00003133 content-length. The problem had been corrected in the 2.4 branch, but never

Nick Coghlanc060b0e2008-07-02 13:09:19 +00003149- Issue #3190: Pydoc now hides the automatic module attribute __package__ (the

3492 large to fit in a C long. ldexp(x, n) now returns a zero (with
3493 suitable sign) if n is large and negative; previously, it raised

Ronald Oussoren5640ce22008-06-05 12:58:24 +00003540- On MacOS X it is now possible to install the framework in 64-bit
3541 mode or even as a 4-way universal binary (that is, PPC, i386,
Georg Brandl5cc774e2008-06-11 20:28:06 +00003542 PPC64 and x86_64 support in one binary).
Ronald Oussoren5640ce22008-06-05 12:58:24 +00003543
3544 This is controlled by the configure argument ``--with-universal-archs``:
3545
3546 - ``--with-universal-archs=all``: install 4-way universal
3547
3548 - ``--with-universal-archs=32-bit``: install 2-way universal, 32-bit (the default)
3549
3550 - ``--with-universal-archs=64-bit``: install 2-way universal, 64-bit
3551
3552 This option should be used in combination with ``--enable-universalsdk=``.
3553
3554 NOTE: 64-bit and 4-way builds are only suppported on Mac OS X 10.5 (or later).

Georg Brandl3ee81df2008-05-17 18:14:43 +00003604- Issue #1631171: Re-implement the 'warnings' module in C (the
3605 original Python code has been kept as backup). This will allow for
3606 using the 'warning's machinery in such places as the parser where
3607 use of pure Python code is not possible. Both the ``showarning()``
3608 and ``formatwarning()`` gain an optional 'line' argument which is
3609 not called by default for backwards-compatibility reasons. Setting
3610 ``warnings.showwarning()`` to an implementation that lacks support
3611 for the ``line`` argument will raise a DeprecationWarning.

Georg Brandl3ee81df2008-05-17 18:14:43 +00003674- Issue #2550: The approach used by client/server code for obtaining
3675 ports to listen on in network-oriented tests has been refined in an
3676 effort to facilitate running multiple instances of the entire
3677 regression test suite in parallel without issue.
3678 test_support.bind_port() has been fixed such that it will always
3679 return a unique port -- which wasn't always the case with the
3680 previous implementation, especially if socket options had been set
3681 that affected address reuse (i.e. SO_REUSEADDR, SO_REUSEPORT). The
3682 new implementation of bind_port() will actually raise an exception
3683 if it is passed an AF_INET/SOCK_STREAM socket with either the
3684 SO_REUSEADDR or SO_REUSEPORT socket option set. Furthermore, if
3685 available, bind_port() will set the SO_EXCLUSIVEADDRUSE option on
3686 the socket it's been passed. This currently only applies to
3687 Windows. This option prevents any other sockets from binding to the
3688 host/port we've bound to, thus removing the possibility of the
3689 'non-deterministic' behaviour, as Microsoft puts it, that occurs
3690 when a second SOCK_STREAM socket binds and accepts to a host/port
3691 that's already been bound by another socket. The optional preferred
3692 port parameter to bind_port() has been removed. Under no
3693 circumstances should tests be hard coding ports!
3694
3695 test_support.find_unused_port() has also been introduced, which will
3696 pass a temporary socket object to bind_port() in order to obtain an
3697 unused port. The temporary socket object is then closed and
3698 deleted, and the port is returned. This method should only be used
3699 for obtaining an unused port in order to pass to an external program
3700 (i.e. the -accept [port] argument to openssl's s_server mode) or as
3701 a parameter to a server-oriented class that doesn't give you direct
3702 access to the underlying socket used.
3703
3704 Finally, test_support.HOST has been introduced, which should be used
3705 for the host argument of any relevant socket calls (i.e. bind and
3706 connect).
Trent Nelsone41b0062008-04-08 23:47:30 +00003707
3708 The following tests were updated to following the new conventions:
Georg Brandl3ee81df2008-05-17 18:14:43 +00003709 test_socket, test_smtplib, test_asyncore, test_ssl, test_httplib,
Trent Nelsone41b0062008-04-08 23:47:30 +00003710 test_poplib, test_ftplib, test_telnetlib, test_socketserver,
3711 test_asynchat and test_socket_ssl.
3712
Georg Brandl3ee81df2008-05-17 18:14:43 +00003713 It is now possible for multiple instances of the regression test
3714 suite to run in parallel without issue.

Amaury Forgeot d'Arc9a0d3462008-03-23 09:55:29 +00003768- Issue #1477: With narrow Unicode builds, the unicode escape sequence
Georg Brandl3ee81df2008-05-17 18:14:43 +00003769 \Uxxxxxxxx did not accept values outside the Basic Multilingual
3770 Plane. This affected raw unicode literals and the
3771 'raw-unicode-escape' codec. Now UTF-16 surrogates are generated in
3772 this case, like normal unicode literals and the 'unicode-escape'
3773 codec.

3981-----------------
3982
Fred Drakea8ee94b2008-03-01 02:45:07 +00003983- Issue #2051: pyc and pyo files are no longer created with permission
Barry Warsaw52973612008-03-01 02:23:38 +00003984 644. The mode is now inherited from the py file.

3987
3988- Patch #1759: Backport of PEP 3129 class decorators.
Christian Heimes5224d282008-02-23 15:01:05 +00003989
Vinay Sajipb7edfc42008-04-02 21:10:23 +00003990- Issue #1881: An internal parser limit has been increased. Also see
Facundo Batistafc2d0102008-02-23 12:01:13 +00003991 issue 215555 for a discussion.
3992
Eric Smitha73fbe72008-02-23 03:09:44 +00003993- Added the future_builtins module, which contains hex() and oct().
3994 These are the PEP 3127 version of these functions, designed to be
3995 compatible with the hex() and oct() builtins from Python 3.0. They
3996 differ slightly in their output formats from the existing, unchanged
3997 Python 2.6 builtins. The expected usage of the future_builtins
3998 module is:
3999 from future_builtins import hex, oct
4000
Eric Smith7ef40bf2008-02-20 23:34:22 +00004001- Issue #1600: Modifed PyOS_ascii_formatd to use at most 2 digit
4002 exponents for exponents with absolute value < 100. Follows C99
4003 standard. This is a change on Windows, which would use 3 digits.
4004 Also, added 'n' to the formats that PyOS_ascii_formatd understands,
4005 so that any alterations it does to the resulting string will be
4006 available in stringlib/formatter.h (for float.__format__).
4007
Eric Smith5a3c1352008-02-19 13:21:56 +00004008- Implemented PEP 3101, Advanced String Formatting. This adds a new
4009 builtin format(); a format() method for str and unicode; a
4010 __format__() method to object, str, unicode, int, long, float, and
4011 datetime; the class string.Formatter; and the C API
4012 PyObject_Format().
4013
Georg Brandl3ee81df2008-05-17 18:14:43 +00004014- Fixed several potential crashes, all caused by specially crafted
4015 __del__ methods exploiting objects in temporarily inconsistent
4016 state.
Amaury Forgeot d'Arc632fad32008-02-16 20:55:24 +00004017
Vinay Sajipb7edfc42008-04-02 21:10:23 +00004018- Issue #2115: Important speedup in setting __slot__ attributes. Also
Georg Brandl3ee81df2008-05-17 18:14:43 +00004019 prevent a possible crash: an Abstract Base Class would try to access
4020 a slot on a registered virtual subclass.
Amaury Forgeot d'Arc60d6c7f2008-02-15 21:22:45 +00004021

Georg Brandl3ee81df2008-05-17 18:14:43 +00004025- Clear all free lists during a gc.collect() of the highest generation
4026 in order to allow pymalloc to free more arenas. Python may give back
4027 memory to the OS earlier.
Christian Heimes3b718a72008-02-14 12:47:33 +00004028
Georg Brandl3ee81df2008-05-17 18:14:43 +00004029- Issue #2045: Fix an infinite recursion triggered when printing a
4030 subclass of collections.defaultdict, if its default_factory is set
4031 to a bound method.
Amaury Forgeot d'Arcb01aa432008-02-08 00:56:02 +00004032
Christian Heimesf75dbef2008-02-08 00:11:31 +00004033- Fixed a minor memory leak in dictobject.c. The content of the free
4034 list was not freed on interpreter shutdown.
4035
Georg Brandl21e99f42010-03-07 15:23:59 +00004036- Limit free list of method and built-in function objects to 256
Georg Brandl3ee81df2008-05-17 18:14:43 +00004037 entries each.
Christian Heimes6075a822008-02-06 12:44:34 +00004038
Georg Brandl3ee81df2008-05-17 18:14:43 +00004039- Patch #1953: Added ``sys._compact_freelists()`` and the C API
4040 functions ``PyInt_CompactFreeList`` and ``PyFloat_CompactFreeList``
Christian Heimes422051a2008-02-04 18:00:12 +00004041 to compact the internal free lists of pre-allocted ints and floats.
4042
Georg Brandl3ee81df2008-05-17 18:14:43 +00004043- Issue #1983: Fixed return type of fork(), fork1() and forkpty()
4044 calls. Python expected the return type int but the fork familie
4045 returns pi_t.
Christian Heimes951cc0f2008-01-31 23:08:23 +00004046
Georg Brandl3ee81df2008-05-17 18:14:43 +00004047- Issue #1678380: Fix a bug that identifies 0j and -0j when they

Georg Brandl3ee81df2008-05-17 18:14:43 +00004059- Patch #1473257: generator objects gain a gi_code attribute. This is
4060 the same object as the func_code attribute of the function that
4061 produced the generator.
Georg Brandl0cdf9a32008-01-26 14:14:20 +00004062
Georg Brandl3ee81df2008-05-17 18:14:43 +00004063- Issue #1920: "while 0" statements were completely removed by the
4064 compiler, even in the presence of an "else" clause, which is
4065 supposed to be run when the condition is false. Now the compiler
4066 correctly emits bytecode for the "else" suite.
Amaury Forgeot d'Arc31eaafe2008-01-24 22:59:25 +00004067
Guido van Rossumeead05f2008-01-24 18:21:02 +00004068- A few crashers fixed: weakref_in_del.py (issue #1377858);
4069 loosing_dict_ref.py (issue #1303614, test67.py);
4070 borrowed_ref_[34].py (not in tracker).
4071
Vinay Sajipd7cf32e2008-01-24 12:43:33 +00004072- Issue #1069410: The "can't load dll" message box on Windows is
Christian Heimesb2302ba2008-01-23 17:15:06 +00004073 suppressed while an extension is loaded by calling SetErrorMode in
4074 dynload_win.c. The error is still reported properly.
4075
Georg Brandl3ee81df2008-05-17 18:14:43 +00004076- Issue #1915: Python compiles with --enable-unicode=no again. However
Christian Heimes082c9b02008-01-23 14:20:50 +00004077 several extension methods and modules do not work without unicode
4078 support.
4079
Georg Brandl26543b12008-01-21 18:36:51 +00004080- Issue #1882: when compiling code from a string, encoding cookies in the

4084
Georg Brandl6caad7d2008-01-26 14:19:22 +00004085- Issue #1865: ``bytes`` as an alias for ``str`` and b"" as an alias "" were
Christian Heimes288e89a2008-01-18 18:24:07 +00004086 added.
4087
Christian Heimesc94e2b52008-01-14 04:13:37 +00004088- sys.float_info / PyFloat_GetInfo: The floating point information
4089 object was converted from a dict to a specialized structseq object.
4090
Georg Brandl3ee81df2008-05-17 18:14:43 +00004091- Patch #1816: Added sys.flags structseq. It exposes the status of
4092 most command line arguments and PYTHON* environment variables.
Christian Heimesf31b69f2008-01-14 03:42:48 +00004093
Georg Brandl3ee81df2008-05-17 18:14:43 +00004094- Objects/structseq.c: Implemented new structseq representation. The
4095 patch makes structseqs (e.g. the return value of os.stat) more
4096 readable.
Christian Heimes9c201962008-01-14 03:33:52 +00004097
Georg Brandl3ee81df2008-05-17 18:14:43 +00004098- Patch #1700288: added a type attribute cache that caches method
4099 accesses, resulting in speedups in heavily object-oriented code.
Amaury Forgeot d'Arce4c270c2008-01-14 00:29:41 +00004100
Neal Norwitz3fc15b82008-01-10 05:42:58 +00004101- Bug #1776: __import__() no longer accepts filenames on any platform.
4102 The first parameter to __import__() must be a valid module name.
Christian Heimes3403f152008-01-09 19:56:33 +00004103
Georg Brandlaed6c662008-01-07 17:25:53 +00004104- Patch #1668: renamed THREADDEBUG envvar to PYTHONTHREADDEBUG.
4105
Georg Brandl3ee81df2008-05-17 18:14:43 +00004106- Patch #602345: Add -B command line option, PYTHONDONTWRITEBYTECODE
4107 envvar and sys.dont_write_bytecode attribute. All these can be set
4108 to forbid Python to attempt to write compiled bytecode files.
Georg Brandl2da0fce2008-01-07 17:09:35 +00004109
Georg Brandl3ee81df2008-05-17 18:14:43 +00004110- Improve some exception messages when Windows fails to load an
4111 extension module. Now we get for example '%1 is not a valid Win32
4112 application' instead of 'error code 193'.
Amaury Forgeot d'Arce0b76952008-01-04 02:04:15 +00004113

Christian Heimes0a8143f2007-12-18 23:22:54 +00004119- Issue #1635: Platform independent creation and representation of NaN
Georg Brandl3ee81df2008-05-17 18:14:43 +00004120 and INF. float("nan"), float("inf") and float("-inf") now work on
4121 every platform with IEEE 754 semantics.
Christian Heimes0a8143f2007-12-18 23:22:54 +00004122
Georg Brandl3ee81df2008-05-17 18:14:43 +00004123- Compiler now generates simpler and faster code for dictionary
4124 literals. The oparg for BUILD_MAP now indicates an estimated
4125 dictionary size. There is a new opcode, STORE_MAP, for adding
4126 entries to the dictionary.

Georg Brandl3ee81df2008-05-17 18:14:43 +00004155- Patch #1739468: Directories and zipfiles containing a __main__.py
4156 file can now be directly executed by passing their name to the
4157 interpreter. The directory/zipfile is automatically inserted as the
4158 first entry in sys.path.
Nick Coghlan327a39b2007-11-18 11:56:28 +00004159
Georg Brandl3ee81df2008-05-17 18:14:43 +00004160- Issue #1265: Fix a problem with sys.settrace, if the tracing
4161 function uses a generator expression when at the same time the
4162 executed code is closing a paused generator.
Amaury Forgeot d'Arc0d75f092007-11-13 21:54:28 +00004163
Raymond Hettinger1760c8a2007-11-08 02:52:43 +00004164- sets and frozensets now have an isdisjoint() method.
4165
Raymond Hettinger3f8caa32007-10-24 01:28:33 +00004166- optimize the performance of builtin.sum().

4169
Georg Brandl21e99f42010-03-07 15:23:59 +00004170- The enumerate() built-in function is no longer bounded to sequences
Georg Brandl3ee81df2008-05-17 18:14:43 +00004171 smaller than LONG_MAX. Formerly, it raised an OverflowError. Now,
4172 automatically shifts from ints to longs.
Raymond Hettinger8f669372007-10-03 21:18:11 +00004173
Georg Brandl3ee81df2008-05-17 18:14:43 +00004174- Issue #1686386: Tuple's tp_repr did not take into account the
4175 possibility of having a self-referential tuple, which is possible
4176 from C code. Nor did object's tp_str consider that a type's tp_str
4177 could do something that could lead to an inifinite recursion.
4178 Py_ReprEnter() and Py_EnterRecursiveCall(), respectively, fixed the
4179 issues.
Brett Cannon0b14f242007-09-30 19:45:10 +00004180
Georg Brandl3ee81df2008-05-17 18:14:43 +00004181- Issue #1164: It was possible to trigger deadlock when using the
4182 'print' statement to write to a file since the GIL was not released
4183 as needed. Now PyObject_Print() does the right thing along with
4184 various tp_print implementations of the built-in types and those in
4185 the collections module.
Brett Cannon01531592007-09-17 03:28:34 +00004186
Georg Brandl3ee81df2008-05-17 18:14:43 +00004187- Issue #1147: Exceptions were directly allowing string exceptions in
4188 their throw() method even though string exceptions no longer
4189 allowed.

Brett Cannona0c05512007-09-10 21:38:27 +00004193
Brett Cannon1e534b52007-09-07 04:18:30 +00004194- Issue #1202533: Fix infinite recursion calls triggered by calls to
Georg Brandl3ee81df2008-05-17 18:14:43 +00004195 PyObject_Call() never calling back out to Python code to trigger
4196 recursion depth updates/checks. Required the creation of a static
4197 RuntimeError instance in case normalizing an exception put the
4198 recursion check value past its limit. Fixes crashers
4199 infinite_rec_(1|2|4|5).py.
Brett Cannon1e534b52007-09-07 04:18:30 +00004200

Neal Norwitz0ac60192007-05-27 04:08:54 +00004214- Add new attribute names for function objects. All the func_* become
Georg Brandl3ee81df2008-05-17 18:14:43 +00004215 __*__ attributes. (Some already existed, e.g., __doc__ and
4216 __name__.)

4222 calls.
4223
Collin Winter62903052007-05-18 23:11:24 +00004224- except clauses may now be spelled either "except E, target:" or
Georg Brandl3ee81df2008-05-17 18:14:43 +00004225 "except E as target:". This is to provide forwards compatibility
4226 with Python 3.0.

Armin Rigo9790a272007-05-02 19:23:31 +00004232
Vinay Sajip8549ce32007-05-06 17:53:37 +00004233- When __slots__ are set to a unicode string, make it work the same as
Neal Norwitzcbd9ee62007-04-14 05:25:50 +00004234 setting a plain string, ie don't expand to single letter identifiers.
4235
Raymond Hettinger13936692007-04-11 18:40:58 +00004236- Request #1191699: Slices can now be pickled.
4237
Raymond Hettinger4db5fe92007-04-12 04:10:00 +00004238- Request #1193128: str.translate() now allows a None argument for
4239 translations that only remove characters without re-mapping the
4240 remaining characters.
4241
Georg Brandl5cb76c12007-03-21 09:00:39 +00004242- Patch #1682205: a TypeError while unpacking an iterable is no longer
4243 masked by a generic one with the message "unpack non-sequence".
4244

4246
Guido van Rossum143b5642007-03-23 04:58:42 +00004247- Bug #1683368: The object.__init__() and object.__new__() methods are
4248 now stricter in rejecting excess arguments. The only time when
4249 either allows excess arguments is when it is not overridden and the
4250 other one is. For backwards compatibility, when both are
4251 overridden, it is a deprecation warning (for now; maybe a Py3k
Guido van Rossum234b1ff2007-03-23 19:39:01 +00004252 warning later). Also, type.__init__() insists on the same signature
4253 as supported by type.__new__().

Georg Brandl3ee81df2008-05-17 18:14:43 +00004255- Patch #1675423: PyComplex_AsCComplex() now tries to convert an
4256 object to complex using its __complex__() method before falling back
4257 to the __float__() method. Therefore, the functions in the cmath
4258 module now can operate on objects that define a __complex__()
4259 method.

4279
Georg Brandl871f1bc2007-03-12 13:17:36 +00004280- The dir() function has been extended to call the __dir__() method on
Georg Brandl3ee81df2008-05-17 18:14:43 +00004281 its argument, if it exists. If not, it will work like before. This
4282 allows customizing the output of dir() in the presence of a
4283 __getattr__().

Georg Brandlaa2321b2007-03-07 00:40:28 +00004295- Patch #703779: unset __file__ in __main__ after running a file. This
Georg Brandl3ee81df2008-05-17 18:14:43 +00004296 makes the filenames the warning module prints much more sensible
4297 when a PYTHONSTARTUP file is used.

4311 sq_ass_slice instead of the sq_slice slot.
4312
Georg Brandl3ee81df2008-05-17 18:14:43 +00004313- When printing an unraisable error, don't print exceptions. before

Georg Brandl2c1375c2006-10-12 11:27:59 +00004365- Bug #1545497: when given an explicit base, int() did ignore NULs
4366 embedded in the string to convert.
4367
Georg Brandl846f73a2006-10-08 07:11:54 +00004368- Bug #1569998: break inside a try statement (outside a loop) is now
4369 recognized and rejected.
4370

Armin Rigo7ccbca92006-10-04 12:17:45 +00004373- A number of places, including integer negation and absolute value,
4374 were fixed to not rely on undefined behaviour of the C compiler
4375 anymore.

Georg Brandl4e933132006-09-06 20:05:58 +00004398- Bug #1542051: Exceptions now correctly call PyObject_GC_UnTrack.

Georg Brandl3ee81df2008-05-17 18:14:43 +00004416 generator expressions (x for x, in ... ) works again. Fixing this
4417 problem required changing the .pyc magic number. This means that
4418 .pyc files generated before 2.5c2 will be regenerated.

5223 members).
Walter Dörwald84a3efe2007-06-13 16:57:12 +00005224
Georg Brandl3ee81df2008-05-17 18:14:43 +00005225- Issue #829951: In the smtplib module, SMTP.starttls() now complies
5226 with RFC 3207 and forgets any knowledge obtained from the server not
5227 obtained from the TLS negotiation itself. Patch contributed by Bill
5228 Fenner.
Gregory P. Smith2b3ba582008-01-17 08:03:17 +00005229
Georg Brandl3ee81df2008-05-17 18:14:43 +00005230- Issue #1339: The smtplib.SMTP class has been refactored a bit such
Gregory P. Smithbde4ae42008-01-17 08:35:49 +00005231 that the SMTP.starttls() caller no longer needs to call ehlo()
5232 beforehand. SMTP.starttls() now raises an exception of the server
Georg Brandl3ee81df2008-05-17 18:14:43 +00005233 does not claim to support starttls. Adds the
5234 SMTP.ehlo_or_helo_if_needed() method. Patch contributed by Bill
5235 Fenner.

5304 contents before adding elements from the iterable. This fix brings
5305 the behavior into line with that for list.__init__().
Raymond Hettingeradf9ffd2007-12-13 00:08:37 +00005306
Georg Brandl3ee81df2008-05-17 18:14:43 +00005307- Added wide char functions to msvcrt module: getwch, getwche, putwch

5315 complex, tuple, list, dict, set, and frozenset. Formerly, it would
5316 silently miscode subclasses of those types. Now, it raises a
5317 ValueError instead.
Raymond Hettinger12e94202007-11-07 01:13:09 +00005318

Georg Brandl3ee81df2008-05-17 18:14:43 +00005333 time so that opening a database previously created with the DB_DUP
5334 or DB_DUPSORT flag set will keep the proper behavior on subsequent
5335 opens. Specifically: dictionary assignment to a DB object will
5336 replace all values for a given key when the database allows
5337 duplicate values. DB users should use DB.put(k, v) when they want
5338 to store duplicates; not DB[k] = v.
Gregory P. Smithec10a4a2007-11-05 02:32:26 +00005339

5345 characters with ASCII value less than 32. Also, it correctly quotes
5346 dots only if they occur on a single line, as opposed to the previous
5347 behavior of quoting dots if they are the second character of any
5348 line.
Georg Brandl4aef7272007-03-13 22:49:43 +00005349
