Mark Dickinsona8d26682010-05-04 16:18:25 +000034- Issue #1533: fix inconsistency in range function argument
35 processing: any non-float non-integer argument is now converted to
36 an integer (if possible) using its __int__ method. Previously, only
37 small arguments were treated this way; larger arguments (those whose
38 __int__ was outside the range of a C long) would produce a TypeError.

48 benefit compared to the dynamic memory allocation fallback. Patch by
49 Charles-François Natali.

71- Issue #8483: asyncore.dispatcher's __getattr__ method produced confusing
72 error messages when accessing undefined class attributes because of the cheap
73 inheritance with the underlying socket object.
74 The cheap inheritance has been deprecated.

85 ASCII with backslashreplace error handler if str(value) failed
86
Mark Dickinson4f96f5f2010-05-04 14:25:50 +000087- Issue #8567: Fix precedence of signals in Decimal module: when a
88 Decimal operation raises multiple signals and more than one of those
89 signals is trapped, the specification determines the order in which
90 the signals should be handled. In many cases this order wasn't
91 being followed, leading to the wrong Python exception being raised.
92
Antoine Pitrouf7fd8e42010-05-03 16:25:33 +000093- Issue #7865: The close() method of :mod:`io` objects should not swallow

122 suites, the IGNORE_EXCEPTION_DETAIL directive now also ignores the module
Nick Coghlan54677da2010-04-28 14:34:30 +0000123 location of the raised exception. Based on initial patch by Lennart
124 Regebro.

140 witnessed in test_httpservers.
141
Antoine Pitroufc69af12010-04-24 20:04:58 +0000142- Issue #5103: SSL handshake would ignore the socket timeout and block
143 indefinitely if the other end didn't respond.
144
Antoine Pitrou4d3e3722010-04-24 19:57:01 +0000145- The do_handshake() method of SSL objects now adjusts the blocking mode of
146 the SSL structure if necessary (as other methods already do).

161 a non-infinite timeout. Also make that method friendlier with applications
162 wanting to continue using the socket in clear-text mode, by disabling
163 OpenSSL's internal readahead. Thanks to Darryl Miles for guidance.
164
Antoine Pitrouc715a9e2010-04-21 19:28:03 +0000165- Issue #8484: Load all ciphers and digest algorithms when initializing
166 the _ssl extension, such that verification of some SSL certificates
167 doesn't fail because of an "unknown algorithm".

280 is called with a non-empty format string. This is an effort to
281 future-proof user code. If a derived class does not currently

317
Mark Dickinson8a950712010-04-03 15:47:46 +0000318- Issue #8257: The Decimal construct now accepts a float instance
319 directly, converting that float to a Decimal of equal value:
320
321 >>> Decimal(1.1)
322 Decimal('1.100000000000000088817841970012523233890533447265625')

325
Raymond Hettingera551f312010-04-04 18:34:45 +0000326- the functools module now has a total_ordering() class decorator
Georg Brandl4fabac52010-04-14 08:53:38 +0000327 to simplify the specification of rich comparisons.
Raymond Hettingera551f312010-04-04 18:34:45 +0000328
Raymond Hettingerbb006cf2010-04-04 21:45:01 +0000329- The functools module also adds cmp_to_key() as a tool to transition
Raymond Hettingera551f312010-04-04 18:34:45 +0000330 old-style comparison functions to new-style key-functions.

336 signal InvalidOperation instead of returning False. (Comparisons
Mark Dickinsonf3eeca12010-04-02 10:35:12 +0000337 involving a quiet NaN are unchanged.) Also, Decimal quiet NaNs
338 are now hashable; Decimal signaling NaNs remain unhashable.

341 instances now return a result based on the numeric values of the
342 operands; previously they returned an arbitrary result based on
343 the relative ordering of id(float) and id(Decimal).
344
Barry Warsawf7f2d6f2010-03-31 21:07:16 +0000345- Issue #8233: When run as a script, py_compile.py optionally takes a single
346 argument `-` which tells it to read files to compile from stdin. Each line
347 is read on demand and the named file is compiled immediately. (Original
348 patch by Piotr Ożarowski).

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

Mark Dickinson4846a8e2010-04-03 14:05:10 +0000460- Issue #8300: When passing a non-integer argument to struct.pack with any
461 integer format code, struct.pack first attempts to convert the non-integer
462 using its __index__ method. If that method is non-existent or raises
463 TypeError it goes on to try the __int__ method, as described below.
464
Georg Brandlba83f822010-03-14 09:50:54 +0000465- Issue #1530559: When passing a non-integer argument to struct.pack with *any*
466 integer format code (one of 'bBhHiIlLqQ'), struct.pack attempts to use the
467 argument's __int__ method to convert to an integer before packing. It also
468 produces a DeprecationWarning in this case. (In Python 2.6, the behaviour
469 was inconsistent: __int__ was used for some integer codes but not for others,
470 and the set of integer codes for which it was used differed between native
471 packing and standard packing.)

712 and add the additional members returned in an OSVERSIONINFOEX structure. The
713 new members are service_pack_major, service_pack_minor, suite_mask, and
714 product_type.

729 strings,
730 (2) a crash in dtoa.c that occurred in debug builds when parsing certain long
731 numeric strings corresponding to subnormal values,
732 (3) a memory leak for some values large enough to cause overflow, and
733 (4) a number of flaws that could lead to incorrectly rounded results.

Antoine Pitroud840e512010-02-04 20:20:18 +0000761- Issue #4772: Raise a ValueError when an unknown Bluetooth protocol is
Georg Brandlba83f822010-03-14 09:50:54 +0000762 specified, rather than fall through to AF_PACKET (in the ``socket`` module).
Antoine Pitroud840e512010-02-04 20:20:18 +0000763 Also, raise ValueError rather than TypeError when an unknown TIPC address

Antoine Pitrouf3fa0742010-01-31 22:26:04 +0000768- Issue #6939: Fix file I/O objects in the `io` module to keep the original
Georg Brandlba83f822010-03-14 09:50:54 +0000769 file position when calling `truncate()`. It would previously change the file
770 position to the given argument, which goes against the tradition of
Antoine Pitrouf3fa0742010-01-31 22:26:04 +0000771 ftruncate() and other truncation APIs. Patch by Pascal Chambon.

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

Georg Brandlba83f822010-03-14 09:50:54 +0000790- Issue #7748: Since unicode values are supported for some metadata options in
791 Distutils, the DistributionMetadata get_* methods will now return an utf-8
792 encoded string for them. This ensures that the upload and register commands
793 send the correct values to PyPI without any error.

867Core and Builtins
868-----------------
869
Georg Brandlba83f822010-03-14 09:50:54 +0000870- The ``__complex__()`` method is now looked up on the class of instances to
871 make it consistent with other special methods.

875
Mark Dickinson1b34d252010-01-01 17:27:30 +0000876- Issue #5080: A number of functions and methods previously produced a
Georg Brandlba83f822010-03-14 09:50:54 +0000877 DeprecationWarning when passed a float argument where an integer was expected.
878 These functions and methods now raise TypeError instead. The majority of the
879 effects of this change are in the extension modules, but some core functions
880 and methods are affected: notably the 'chr', 'range' and 'xrange' builtins,
881 and many unicode/str methods.

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

Georg Brandlba83f822010-03-14 09:50:54 +0000906 These executables now work properly with the arch(1) command: ``arch -ppc
907 python`` will start a universal binary version of python in PPC mode (unlike
908 previous releases).

Georg Brandlba83f822010-03-14 09:50:54 +00001064- Issue #7117: ``repr(x)`` for a float x returns a result based on the shortest
1065 decimal string that's guaranteed to round back to x under correct rounding
1066 (with round-half-to-even rounding mode). Previously it gave a string based on
1067 rounding x to 17 decimal digits. repr(x) for a complex number behaves
1068 similarly. On platforms where the correctly-rounded strtod and dtoa code is
1069 not supported (see below), repr is unchanged.

Georg Brandlba83f822010-03-14 09:50:54 +00001071- Issue #7117: On almost all platforms: float-to-string and string-to-float
1072 conversions within Python are now correctly rounded. Places these conversions
1073 occur include: str for floats and complex numbers; the float and complex
1074 constructors; old-style and new-style numeric formatting; serialization and
1075 deserialization of floats and complex numbers using marshal, pickle and json;
1076 parsing of float and imaginary literals in Python code; Decimal-to-float
1077 conversion.
Mark Dickinsonb678de82009-11-19 18:41:49 +00001078
Georg Brandlba83f822010-03-14 09:50:54 +00001079 The conversions use a Python-adapted version of David Gay's well-known dtoa.c,
1080 providing correctly-rounded strtod and dtoa C functions. This code is
1081 supported on Windows, and on Unix-like platforms using gcc, icc or suncc as
1082 the C compiler. There may be a small number of platforms on which correct
1083 operation of this code cannot be guaranteed, so the code is not used: notably,
1084 this applies to platforms where the C double format is not IEEE 754 binary64,
1085 and to platforms on x86 hardware where the x87 FPU is set to 64-bit precision
1086 and Python's configure script is unable to determine how to change the FPU
1087 precision. On these platforms conversions use the platform strtod and dtoa,
1088 as before.

Georg Brandlba83f822010-03-14 09:50:54 +00001090- Issue #7117: Backport round implementation from Python 3.x. ``round()`` now
1091 uses the correctly-rounded string <-> float conversions described above (when
1092 available), and so produces correctly rounded results that will display nicely
1093 under the float repr. There are two related small changes: (1) round now
1094 accepts any class with an ``__index__()`` method for its second argument (but
1095 no longer accepts floats for the second argument), and (2) an excessively
1096 large second integer argument (e.g., ``round(1.234, 10**100)``) no longer
1097 raises an exception.

1476 this code path is really executed because I cannot move to such directory on
1477 win2k)

1503 PyUnicode_DecodeUTF8() once, remember the result and output it in a second

2679 'b', 'B', 'h', 'H', 'i', 'l', '*b', '*h' ,'*i', '*l', and an x with a
2680 __long__ method could be packed by 'q', 'Q', '*q', '*Q'; for x with
2681 neither __int__ nor __long__, TypeError used to be raised (with a

Amaury Forgeot d'Arc05e34492008-09-10 22:04:45 +00002880- Issue #3743: In a few places, PY_FORMAT_SIZE_T was incorrectly used with
2881 PyString_FromFormat or PyErr_Format to display size_t values. The macro
2882 PY_FORMAT_SIZE_T is designed to select the correct format for the OS
2883 ``printf`` function, whereas PyString_FromFormat has an independent
2884 implementation and uses "%zd" on all platforms for size_t values.
2885 This makes a difference on win64, where ``printf`` needs "%Id" to display

2981 warnings.catch_warnings() along with some API cleanup. Expanding the tests
2982 for catch_warnings() also led to an improvement in the raising of a

Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00003049What's New in Python 2.6 beta 3?
3050================================
3051
Barry Warsaw07a4a382008-08-21 01:15:08 +00003052*Release date: 20-Aug-2008*
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00003053
3054Core and Builtins
3055-----------------
3056
Guido van Rossumf8402962008-08-20 15:01:50 +00003057- Issue #1878: Remove Py_TPFLAGS_HAVE_VERSION_TAG from
3058 Py_TPFLAGS_DEFAULT when not building the core. This means 3rd party
3059 extensions do not automatically benefit from the class attribute
3060 cache; they will have to explicitly add Py_TPFLAGS_HAVE_VERSION_TAG
3061 to their tp_flags field if they care. This is a backwards
3062 compatibility feature; in 3.0, all types will use the cache by
3063 default.
3064
Benjamin Petersonf647dc12008-08-20 01:27:30 +00003065- Keyword arguments can now follow starred arguments. (``f(a, *args,
3066 keyword=23)`` is now valid syntax.)
3067
Thomas Heller0ad5ae02008-08-19 19:25:04 +00003068- ctypes function pointers that are COM methods have a boolean True
3069 value again.
3070
Martin v. Löwisf91d46a2008-08-12 14:49:50 +00003071- Issue #3139: Make buffer-interface thread-safe wrt. PyArg_ParseTuple,
3072 by denying s# to parse objects that have a releasebuffer procedure,
3073 and introducing s*.
3074
Georg Brandl1e13ea92008-08-11 09:07:59 +00003075- Issue #3537: Fix an assertion failure when an empty but presized dict
3076 object was stored in the freelist.
3077
Mark Dickinsonb6467572008-08-04 21:30:09 +00003078- Issue #1481296: Make long(float('nan')) and int(float('nan')) raise
3079 ValueError consistently across platforms.
3080
Amaury Forgeot d'Arc39fd6722008-07-31 21:28:03 +00003081- Issue #3479: On platforms where sizeof(int) is smaller than sizeof(long)
3082 (64bit Unix, for example), unichr() would truncate its argument and return
3083 u'\x00' for unichr(2**32). Now it properly raises an OverflowError.
3084
Neal Norwitze7d8be82008-07-31 17:17:14 +00003085- Apply security patches from Apple.
3086
Amaury Forgeot d'Arc246daed2008-07-31 00:42:16 +00003087- Issue #2542: Now that issubclass() may call arbitrary code, ensure that
3088 PyErr_ExceptionMatches returns 0 when an exception occurs there.
3089
Antoine Pitrou92f82162008-07-25 22:22:08 +00003090- Issue #1819: function calls with several named parameters are now on
3091 average 35% faster (as measured by pybench).
3092
Amaury Forgeot d'Arce4921fe2008-07-21 22:00:38 +00003093- Issue #2378: An unexpected UnboundLocalError or NameError could appear when
3094 the python debugger steps into a class statement: the free variables (local
3095 variables defined in an outer scope) would be deleted from the outer scope.
3096
Gregory P. Smith0470bab2008-07-22 04:46:32 +00003097- Issue #2620: Overflow checking when allocating or reallocating memory
3098 was not always being done properly in some python types and extension
3099 modules. PyMem_MALLOC, PyMem_REALLOC, PyMem_NEW and PyMem_RESIZE have
3100 all been updated to perform better checks and places in the code that
3101 would previously leak memory on the error path when such an allocation
3102 failed have been fixed.

3106
Hirokazu Yamamoto838c79f2008-08-20 13:14:07 +00003107- Issue #3612: Added some missing basic types in ctypes.wintypes.
3108
Benjamin Petersone977ad42008-08-20 01:42:01 +00003109- The methods ``is_in_tuple()``, ``is_vararg()``, and ``is_keywordarg()`` of
3110 symtable.Symbol have been deprecated for removal in 3.0 and the next release.
3111
Amaury Forgeot d'Arc351ffb82008-08-18 19:23:47 +00003112- Issue #2234: distutils failed for some versions of the cygwin compiler. The
3113 version reported by these tools does not necessarily follow the python
3114 version numbering scheme, so the module is less strict when parsing it.
3115
Nick Coghlanf70385a2008-08-18 12:42:46 +00003116- Issue #2235: Added Py3k warnings for types which will become unhashable
3117 under the stricter __hash__ inheritance rules in 3.0. Several types
3118 which did not meet the rules for hash invariants and were already
3119 unhashable in 3.0 have now been explicitly flagged as unhashable in
3120 2.6 as well (collections.Mapping, collections.Set, unittest.TestSuite,
3121 xml.dom.minidom.NamedNodeMap, numbers.Number, UserList.UserList)
3122
Brett Cannon88f801d2008-08-18 00:46:22 +00003123- Update __all__ for cookielib, csv, os, urllib2, and weakref to include things
3124 imported into the module but exposed as part of the module's API.
3125
Brett Cannon7b96f072008-08-18 00:41:11 +00003126- Remove an unneeded import of abc.ABCMeta from 'inspect'.
3127
Brett Cannon46225e72008-08-18 00:36:52 +00003128- Remove unneeded imports of 'sys' and 'warnings' from 'io'.

Brett Cannon25c9d6a2008-08-17 22:10:11 +00003130- Remove unneeded imports of 'warnings' from shelve, filecmp, and dummy_thread.
3131
Hirokazu Yamamoto41a81eb2008-08-17 13:10:46 +00003132- Issue #3575: Incremental decoder's decode function now takes bytearray
3133 by using 's*' instead of 't#'.
3134
Mark Dickinson3e4caeb2009-02-21 20:27:01 +00003135- Issue #2222: Fixed reference leak when occurred os.rename()
Hirokazu Yamamoto7f30a682008-08-17 09:46:56 +00003136 fails unicode conversion on 2nd parameter. (windows only)
3137
Facundo Batista94f243a2008-08-17 03:38:39 +00003138- Issue 2464. urllib2 now supports a malformation in the URL received
3139 in a redirect.
3140
Brett Cannonabe423e2008-08-16 21:47:07 +00003141- Silence the DeprecationWarning raised when importing mimetools in
Brett Cannon721b1452008-08-16 22:00:27 +00003142 BaseHTTPServer, cgi (and rfc822), httplib.
Brett Cannonabe423e2008-08-16 21:47:07 +00003143
Facundo Batistaeb90b782008-08-16 14:44:07 +00003144- Issue #2776: fixed small issue when handling an URL with double slash
3145 after a 302 response in the case of not going through a proxy.
3146
Antoine Pitroub90a8be2008-08-15 21:03:21 +00003147- Issue #2676: in the email package, content-type parsing was hanging on
3148 pathological input because of quadratic or exponential behaviour of a
3149 regular expression.
3150
Antoine Pitrou11ec65d2008-08-14 21:04:30 +00003151- Issue #3476: binary buffered reading through the new "io" library is now
3152 thread-safe.
3153
Brett Cannonbf3157b2008-08-14 05:00:03 +00003154- Silence the DeprecationWarning of rfc822 when it is imported by mimetools
3155 since mimetools itself is deprecated. Because modules are cached, all
3156 subsequent imports of rfc822 will not raise a visible DeprecationWarning.
3157
Antoine Pitrou9fcd4b32008-08-11 17:21:36 +00003158- Issue #3134: shutil referenced undefined WindowsError symbol.
3159
Robert Schuppenies14646332008-08-10 11:01:53 +00003160- Issue #1342811: Fix leak in Tkinter.Menu.delete. Commands associated to
3161 menu entries were not deleted.
3162
Brett Cannon83e81842008-08-09 23:30:55 +00003163- Copied the implementation of reduce() to _functools.reduce() to have a
3164 version that did not raise a DeprecationWarning under -3.
3165
Antoine Pitrou76b8bee2008-08-09 17:27:23 +00003166- Issue #3205: When iterating over a BZ2File fails allocating memory, raise
3167 a MemoryError rather than silently stop the iteration.
3168
Guido van Rossum59ce9012008-08-09 14:55:34 +00003169- Issue #3487: sre "bytecode" validator. Passing invalid "re-bytecode"
3170 to _sre.compile() will now be rejected. This should not affect anybody
3171 since the re.compile() function never generates invalid re-bytecode.
3172
Skip Montanaroa032bf42008-08-08 22:52:51 +00003173- Issue #3436: Make csv.DictReader's fieldnames attribute a property so that
3174 upon first access it can be automatically initialized from the csv file if
3175 it wasn't initialized during instantiation.

Brett Cannon3aa2a492008-08-06 22:28:09 +00003177- Issue #2338: Create imp.reload() to help with transitioning to Python 3.0 as
3178 the reload() built-in has been removed.
3179
Brett Cannon7e30b672008-08-04 21:52:25 +00003180- Changed code in the following modules/packages to remove warnings raised
Brett Cannonc1b76e42008-08-09 23:06:16 +00003181 while running under the ``-3`` flag: aifc, asynchat, asyncore, bdb, bsddb,

Antoine Pitroude781a42008-08-09 12:43:23 +00003192 asking for a specific length. This problem only affected files opened
3193 using the new "io" module, not the built-in open() function.
Benjamin Peterson01a24322008-07-28 23:35:27 +00003194

3245
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00003246*Release date: 17-Jul-2008*

3249-----------------
3250
Georg Brandl3e483f62008-07-16 22:57:41 +00003251- Issue #3156: Fix inconsistent behavior of the bytearray type: all
3252 its methods now allow for items objects that can be converted to
3253 an integer using operator.index().
3254
Mark Dickinson64b7e502008-07-16 09:40:03 +00003255- Issue #3360: Fix incorrect parsing of '020000000000.0', which
3256 produced a ValueError instead of giving the correct float.
3257
Eric Smitha5fa5a22008-07-16 00:11:49 +00003258- Issue #3083: Add alternate (#) formatting for bin, oct, hex output
3259 for str.format(). This adds the prefix 0b, 0o, or 0x, respectively.
3260
Mark Dickinson7103aa42008-07-15 19:08:33 +00003261- Issue #3008: the float type has a new instance method 'float.hex'
3262 and a new class method 'float.fromhex' to convert floating-point
3263 numbers to and from hexadecimal strings, respectively.
3264
Nick Coghlan6d6bd442008-07-15 15:40:22 +00003265- Issue #2235: __hash__ is once again inherited by default. To allow
3266 collections.Hashable to remain meaningful in the presence of the
3267 default hash implementation (object.__hash__), it is now possible
3268 to explicit block inheritance of hash by setting __hash__=None at
3269 the Python level, or tp_hash=PyObject_HashNotImplemented at the C
3270 level.
3271
Nick Coghlanb028f502008-07-13 14:52:36 +00003272- Issue #3221: Issue a RuntimeWarning instead of raising SystemError if
3273 the parent module cannot be found while performing an absolute import.
3274 This means that an incorrectly defined __package__ attribute will
3275 now only prevent relative imports in that module rather than causing
3276 all imports from that module to fail.
3277
Nick Coghlan14ff9942008-07-08 14:21:42 +00003278- Issue #2517: Allow unicode messages in Exceptions again by correctly
3279 bypassing the instance dictionary when looking up __unicode__ on
3280 new-style classes.

3283 set to a custom object whose write() method happens to install
3284 another file in sys.stdout.
3285
Amaury Forgeot d'Arc1f40c8a2008-06-30 22:42:40 +00003286- Issue #3088: Corrected a race condition in classes derived from
3287 threading.local: the first member set by a thread could be saved in
3288 another thread's dictionary.
3289
Mark Dickinson1ec2fcd2008-06-20 14:53:43 +00003290- Issue #3004: Minor change to slice.indices(): the start and stop
3291 arguments are now treated identically, making the behaviour easier
3292 to describe and understand. For example, slice(None, -10,
3293 1).indices(9) now returns (0, 0, 1) instead of (0, -1, 1), and
3294 slice(None, 10, -1).indices(10) returns (9, 9, -1) instead of (9,
3295 10, -1).
3296
Georg Brandl278fc502008-07-19 12:46:12 +00003297- Issue #3219: Calling a function with repeated keyword arguments,
3298 f(a=2, a=23), would not cause a syntax error. This was a regression
3299 from 2.4 caused by the switch to the new compiler.
Benjamin Peterson175e4d92008-07-01 19:34:52 +00003300
Georg Brandl278fc502008-07-19 12:46:12 +00003301- Issue #2862: Make int and float freelist management consistent with
3302 other freelists. Changes their CompactFreeList apis into
3303 ClearFreeList apis and calls them via gc.collect().

3309 api functions without holding the GIL, which could lead to a fatal
3310 error when they failed.
3311
Martin v. Löwisaabf4042008-08-02 07:20:25 +00003312- Issue #799428: Fix Tkinter.Misc._nametowidget to unwrap Tcl command objects.

Amaury Forgeot d'Arc0f7cddc2008-07-06 21:34:39 +00003337- Issue #839496: SimpleHTTPServer used to open text files in text mode. This is
3338 both unnecessary (HTTP allows text content to be sent in several forms) and
Andrew M. Kuchlingcc3f2b12008-07-10 14:43:31 +00003339 wrong because the actual transmitted size could differ from the
Amaury Forgeot d'Arc0f7cddc2008-07-06 21:34:39 +00003340 content-length. The problem had been corrected in the 2.4 branch, but never
3341 merged into trunk.

Nick Coghlanc060b0e2008-07-02 13:09:19 +00003356- Issue #3190: Pydoc now hides the automatic module attribute __package__ (the
3357 handling is now the same as that of other special attributes like __name__).

Georg Brandl3ee81df2008-05-17 18:14:43 +00003811- Issue #1631171: Re-implement the 'warnings' module in C (the
3812 original Python code has been kept as backup). This will allow for
3813 using the 'warning's machinery in such places as the parser where
3814 use of pure Python code is not possible. Both the ``showarning()``
3815 and ``formatwarning()`` gain an optional 'line' argument which is
3816 not called by default for backwards-compatibility reasons. Setting
3817 ``warnings.showwarning()`` to an implementation that lacks support
3818 for the ``line`` argument will raise a DeprecationWarning.

Georg Brandl3ee81df2008-05-17 18:14:43 +00003881- Issue #2550: The approach used by client/server code for obtaining
3882 ports to listen on in network-oriented tests has been refined in an
3883 effort to facilitate running multiple instances of the entire
3884 regression test suite in parallel without issue.
3885 test_support.bind_port() has been fixed such that it will always
3886 return a unique port -- which wasn't always the case with the
3887 previous implementation, especially if socket options had been set
3888 that affected address reuse (i.e. SO_REUSEADDR, SO_REUSEPORT). The
3889 new implementation of bind_port() will actually raise an exception
3890 if it is passed an AF_INET/SOCK_STREAM socket with either the
3891 SO_REUSEADDR or SO_REUSEPORT socket option set. Furthermore, if
3892 available, bind_port() will set the SO_EXCLUSIVEADDRUSE option on
3893 the socket it's been passed. This currently only applies to
3894 Windows. This option prevents any other sockets from binding to the
3895 host/port we've bound to, thus removing the possibility of the
3896 'non-deterministic' behaviour, as Microsoft puts it, that occurs
3897 when a second SOCK_STREAM socket binds and accepts to a host/port
3898 that's already been bound by another socket. The optional preferred
3899 port parameter to bind_port() has been removed. Under no
3900 circumstances should tests be hard coding ports!
3901
3902 test_support.find_unused_port() has also been introduced, which will
3903 pass a temporary socket object to bind_port() in order to obtain an
3904 unused port. The temporary socket object is then closed and
3905 deleted, and the port is returned. This method should only be used
3906 for obtaining an unused port in order to pass to an external program
3907 (i.e. the -accept [port] argument to openssl's s_server mode) or as
3908 a parameter to a server-oriented class that doesn't give you direct
3909 access to the underlying socket used.
3910
3911 Finally, test_support.HOST has been introduced, which should be used
3912 for the host argument of any relevant socket calls (i.e. bind and
3913 connect).
Trent Nelsone41b0062008-04-08 23:47:30 +00003914
3915 The following tests were updated to following the new conventions:
Georg Brandl3ee81df2008-05-17 18:14:43 +00003916 test_socket, test_smtplib, test_asyncore, test_ssl, test_httplib,
Trent Nelsone41b0062008-04-08 23:47:30 +00003917 test_poplib, test_ftplib, test_telnetlib, test_socketserver,
3918 test_asynchat and test_socket_ssl.
3919
Georg Brandl3ee81df2008-05-17 18:14:43 +00003920 It is now possible for multiple instances of the regression test
3921 suite to run in parallel without issue.

4188-----------------
4189
Fred Drakea8ee94b2008-03-01 02:45:07 +00004190- Issue #2051: pyc and pyo files are no longer created with permission
Barry Warsaw52973612008-03-01 02:23:38 +00004191 644. The mode is now inherited from the py file.

4199
Eric Smitha73fbe72008-02-23 03:09:44 +00004200- Added the future_builtins module, which contains hex() and oct().
4201 These are the PEP 3127 version of these functions, designed to be
4202 compatible with the hex() and oct() builtins from Python 3.0. They
4203 differ slightly in their output formats from the existing, unchanged
4204 Python 2.6 builtins. The expected usage of the future_builtins
4205 module is:
4206 from future_builtins import hex, oct
4207
Eric Smith7ef40bf2008-02-20 23:34:22 +00004208- Issue #1600: Modifed PyOS_ascii_formatd to use at most 2 digit
4209 exponents for exponents with absolute value < 100. Follows C99
4210 standard. This is a change on Windows, which would use 3 digits.
4211 Also, added 'n' to the formats that PyOS_ascii_formatd understands,
4212 so that any alterations it does to the resulting string will be
4213 available in stringlib/formatter.h (for float.__format__).
4214
Eric Smith5a3c1352008-02-19 13:21:56 +00004215- Implemented PEP 3101, Advanced String Formatting. This adds a new
4216 builtin format(); a format() method for str and unicode; a
4217 __format__() method to object, str, unicode, int, long, float, and
4218 datetime; the class string.Formatter; and the C API
4219 PyObject_Format().
4220
Georg Brandl3ee81df2008-05-17 18:14:43 +00004221- Fixed several potential crashes, all caused by specially crafted
4222 __del__ methods exploiting objects in temporarily inconsistent
4223 state.
Amaury Forgeot d'Arc632fad32008-02-16 20:55:24 +00004224
Vinay Sajipb7edfc42008-04-02 21:10:23 +00004225- Issue #2115: Important speedup in setting __slot__ attributes. Also
Georg Brandl3ee81df2008-05-17 18:14:43 +00004226 prevent a possible crash: an Abstract Base Class would try to access
4227 a slot on a registered virtual subclass.

4234 memory to the OS earlier.
Christian Heimes3b718a72008-02-14 12:47:33 +00004235
Georg Brandl3ee81df2008-05-17 18:14:43 +00004236- Issue #2045: Fix an infinite recursion triggered when printing a
4237 subclass of collections.defaultdict, if its default_factory is set
4238 to a bound method.
Amaury Forgeot d'Arcb01aa432008-02-08 00:56:02 +00004239
Christian Heimesf75dbef2008-02-08 00:11:31 +00004240- Fixed a minor memory leak in dictobject.c. The content of the free
4241 list was not freed on interpreter shutdown.
4242
Georg Brandl21e99f42010-03-07 15:23:59 +00004243- Limit free list of method and built-in function objects to 256

4247 functions ``PyInt_CompactFreeList`` and ``PyFloat_CompactFreeList``
Christian Heimes422051a2008-02-04 18:00:12 +00004248 to compact the internal free lists of pre-allocted ints and floats.
4249
Georg Brandl3ee81df2008-05-17 18:14:43 +00004250- Issue #1983: Fixed return type of fork(), fork1() and forkpty()
4251 calls. Python expected the return type int but the fork familie
4252 returns pi_t.

Georg Brandl3ee81df2008-05-17 18:14:43 +00004266- Patch #1473257: generator objects gain a gi_code attribute. This is
4267 the same object as the func_code attribute of the function that
4268 produced the generator.
Georg Brandl0cdf9a32008-01-26 14:14:20 +00004269
Georg Brandl3ee81df2008-05-17 18:14:43 +00004270- Issue #1920: "while 0" statements were completely removed by the
4271 compiler, even in the presence of an "else" clause, which is
4272 supposed to be run when the condition is false. Now the compiler
4273 correctly emits bytecode for the "else" suite.
Amaury Forgeot d'Arc31eaafe2008-01-24 22:59:25 +00004274

4282
Georg Brandl3ee81df2008-05-17 18:14:43 +00004283- Issue #1915: Python compiles with --enable-unicode=no again. However
Christian Heimes082c9b02008-01-23 14:20:50 +00004284 several extension methods and modules do not work without unicode

Georg Brandl6caad7d2008-01-26 14:19:22 +00004292- Issue #1865: ``bytes`` as an alias for ``str`` and b"" as an alias "" were
Christian Heimes288e89a2008-01-18 18:24:07 +00004293 added.
4294
Christian Heimesc94e2b52008-01-14 04:13:37 +00004295- sys.float_info / PyFloat_GetInfo: The floating point information
4296 object was converted from a dict to a specialized structseq object.
4297
Georg Brandl3ee81df2008-05-17 18:14:43 +00004298- Patch #1816: Added sys.flags structseq. It exposes the status of
4299 most command line arguments and PYTHON* environment variables.
Christian Heimesf31b69f2008-01-14 03:42:48 +00004300
Georg Brandl3ee81df2008-05-17 18:14:43 +00004301- Objects/structseq.c: Implemented new structseq representation. The
4302 patch makes structseqs (e.g. the return value of os.stat) more
4303 readable.
Christian Heimes9c201962008-01-14 03:33:52 +00004304
Georg Brandl3ee81df2008-05-17 18:14:43 +00004305- Patch #1700288: added a type attribute cache that caches method
4306 accesses, resulting in speedups in heavily object-oriented code.
Amaury Forgeot d'Arce4c270c2008-01-14 00:29:41 +00004307
Neal Norwitz3fc15b82008-01-10 05:42:58 +00004308- Bug #1776: __import__() no longer accepts filenames on any platform.
4309 The first parameter to __import__() must be a valid module name.
Christian Heimes3403f152008-01-09 19:56:33 +00004310
Georg Brandlaed6c662008-01-07 17:25:53 +00004311- Patch #1668: renamed THREADDEBUG envvar to PYTHONTHREADDEBUG.
4312
Georg Brandl3ee81df2008-05-17 18:14:43 +00004313- Patch #602345: Add -B command line option, PYTHONDONTWRITEBYTECODE
4314 envvar and sys.dont_write_bytecode attribute. All these can be set
4315 to forbid Python to attempt to write compiled bytecode files.
Georg Brandl2da0fce2008-01-07 17:09:35 +00004316
Georg Brandl3ee81df2008-05-17 18:14:43 +00004317- Improve some exception messages when Windows fails to load an
4318 extension module. Now we get for example '%1 is not a valid Win32
4319 application' instead of 'error code 193'.
Amaury Forgeot d'Arce0b76952008-01-04 02:04:15 +00004320
Georg Brandl3ee81df2008-05-17 18:14:43 +00004321- Bug #1481296: Fixed long(float('nan')) != 0L.

Georg Brandl3ee81df2008-05-17 18:14:43 +00004323- Issue #1640: Added math.isinf(x), math.isnan(x) and math.copysign(x,
4324 y) functions.
Christian Heimese2ca4242008-01-03 20:23:15 +00004325
Christian Heimes0a8143f2007-12-18 23:22:54 +00004326- Issue #1635: Platform independent creation and representation of NaN
Georg Brandl3ee81df2008-05-17 18:14:43 +00004327 and INF. float("nan"), float("inf") and float("-inf") now work on
4328 every platform with IEEE 754 semantics.
Christian Heimes0a8143f2007-12-18 23:22:54 +00004329
Georg Brandl3ee81df2008-05-17 18:14:43 +00004330- Compiler now generates simpler and faster code for dictionary
4331 literals. The oparg for BUILD_MAP now indicates an estimated
4332 dictionary size. There is a new opcode, STORE_MAP, for adding
4333 entries to the dictionary.

Andrew M. Kuchling395fe442007-12-05 13:27:20 +00004343- Issue #1553: An erroneous __length_hint__ can make list() raise a
Christian Heimes7cc1c6f2007-12-05 12:52:34 +00004344 SystemError.
4345
Nick Coghlanef01d822007-12-03 12:55:17 +00004346- PEP 366: Allow explicit relative imports when executing modules

4351 running, and if the deallocation of its frames somehow calls the
4352 PyGILState_Ensure() / PyGILState_Release() functions.
Amaury Forgeot d'Arcbe49a902007-11-30 20:37:22 +00004353

Georg Brandl3ee81df2008-05-17 18:14:43 +00004362- Patch #1739468: Directories and zipfiles containing a __main__.py
4363 file can now be directly executed by passing their name to the
4364 interpreter. The directory/zipfile is automatically inserted as the
4365 first entry in sys.path.
Nick Coghlan327a39b2007-11-18 11:56:28 +00004366
Georg Brandl3ee81df2008-05-17 18:14:43 +00004367- Issue #1265: Fix a problem with sys.settrace, if the tracing
4368 function uses a generator expression when at the same time the
4369 executed code is closing a paused generator.
Amaury Forgeot d'Arc0d75f092007-11-13 21:54:28 +00004370
Raymond Hettinger1760c8a2007-11-08 02:52:43 +00004371- sets and frozensets now have an isdisjoint() method.
4372
Raymond Hettinger3f8caa32007-10-24 01:28:33 +00004373- optimize the performance of builtin.sum().
4374
Neal Norwitz44f326e2007-10-05 05:29:17 +00004375- Fix warnings found by the new version of the Coverity checker.
4376
Georg Brandl21e99f42010-03-07 15:23:59 +00004377- The enumerate() built-in function is no longer bounded to sequences
Georg Brandl3ee81df2008-05-17 18:14:43 +00004378 smaller than LONG_MAX. Formerly, it raised an OverflowError. Now,
4379 automatically shifts from ints to longs.
Raymond Hettinger8f669372007-10-03 21:18:11 +00004380
Georg Brandl3ee81df2008-05-17 18:14:43 +00004381- Issue #1686386: Tuple's tp_repr did not take into account the
4382 possibility of having a self-referential tuple, which is possible
4383 from C code. Nor did object's tp_str consider that a type's tp_str
4384 could do something that could lead to an inifinite recursion.
4385 Py_ReprEnter() and Py_EnterRecursiveCall(), respectively, fixed the
4386 issues.
Brett Cannon0b14f242007-09-30 19:45:10 +00004387
Georg Brandl3ee81df2008-05-17 18:14:43 +00004388- Issue #1164: It was possible to trigger deadlock when using the
4389 'print' statement to write to a file since the GIL was not released
4390 as needed. Now PyObject_Print() does the right thing along with
4391 various tp_print implementations of the built-in types and those in
4392 the collections module.
Brett Cannon01531592007-09-17 03:28:34 +00004393
Georg Brandl3ee81df2008-05-17 18:14:43 +00004394- Issue #1147: Exceptions were directly allowing string exceptions in
4395 their throw() method even though string exceptions no longer
4396 allowed.
Brett Cannon4c20bc42007-09-11 21:02:28 +00004397
Georg Brandl3ee81df2008-05-17 18:14:43 +00004398- Issue #1096: Prevent a segfault from getting the repr of a very
4399 deeply nested list by using the recursion counter.
Brett Cannona0c05512007-09-10 21:38:27 +00004400
Brett Cannon1e534b52007-09-07 04:18:30 +00004401- Issue #1202533: Fix infinite recursion calls triggered by calls to
Georg Brandl3ee81df2008-05-17 18:14:43 +00004402 PyObject_Call() never calling back out to Python code to trigger
4403 recursion depth updates/checks. Required the creation of a static
4404 RuntimeError instance in case normalizing an exception put the
4405 recursion check value past its limit. Fixes crashers
4406 infinite_rec_(1|2|4|5).py.
Brett Cannon1e534b52007-09-07 04:18:30 +00004407
Georg Brandl3ee81df2008-05-17 18:14:43 +00004408- Patch #1031213: Decode source line in SyntaxErrors back to its

Neal Norwitz0ac60192007-05-27 04:08:54 +00004421- Add new attribute names for function objects. All the func_* become
Georg Brandl3ee81df2008-05-17 18:14:43 +00004422 __*__ attributes. (Some already existed, e.g., __doc__ and
4423 __name__.)
Neal Norwitz0ac60192007-05-27 04:08:54 +00004424
Neal Norwitz8b2bfbc2007-05-23 06:35:32 +00004425- Add -3 option to the interpreter to warn about features that are
4426 deprecated and will be changed/removed in Python 3.0.
4427
Georg Brandl2134e752007-05-21 20:34:16 +00004428- Patch #1686487: you can now pass any mapping after '**' in function
4429 calls.
4430
Collin Winter62903052007-05-18 23:11:24 +00004431- except clauses may now be spelled either "except E, target:" or
Georg Brandl3ee81df2008-05-17 18:14:43 +00004432 "except E as target:". This is to provide forwards compatibility
4433 with Python 3.0.
Collin Winter62903052007-05-18 23:11:24 +00004434
Brett Cannon229cee22007-05-05 01:34:02 +00004435- Deprecate BaseException.message as per PEP 352.
4436
Georg Brandl3ee81df2008-05-17 18:14:43 +00004437- Issue #1303614: don't expose object's __dict__ when the dict is
Georg Brandl21e99f42010-03-07 15:23:59 +00004438 inherited from a built-in base.
Armin Rigo9790a272007-05-02 19:23:31 +00004439
Vinay Sajip8549ce32007-05-06 17:53:37 +00004440- When __slots__ are set to a unicode string, make it work the same as
Neal Norwitzcbd9ee62007-04-14 05:25:50 +00004441 setting a plain string, ie don't expand to single letter identifiers.
4442
Raymond Hettinger13936692007-04-11 18:40:58 +00004443- Request #1191699: Slices can now be pickled.
4444
Raymond Hettinger4db5fe92007-04-12 04:10:00 +00004445- Request #1193128: str.translate() now allows a None argument for
4446 translations that only remove characters without re-mapping the
4447 remaining characters.
4448
Georg Brandl5cb76c12007-03-21 09:00:39 +00004449- Patch #1682205: a TypeError while unpacking an iterable is no longer
4450 masked by a generic one with the message "unpack non-sequence".
4451
Neal Norwitzaa754b72007-03-21 06:39:48 +00004452- Remove unused file Python/fmod.c.
4453
Guido van Rossum143b5642007-03-23 04:58:42 +00004454- Bug #1683368: The object.__init__() and object.__new__() methods are
4455 now stricter in rejecting excess arguments. The only time when
4456 either allows excess arguments is when it is not overridden and the
4457 other one is. For backwards compatibility, when both are
4458 overridden, it is a deprecation warning (for now; maybe a Py3k
Guido van Rossum234b1ff2007-03-23 19:39:01 +00004459 warning later). Also, type.__init__() insists on the same signature
4460 as supported by type.__new__().
Guido van Rossum143b5642007-03-23 04:58:42 +00004461
Georg Brandl3ee81df2008-05-17 18:14:43 +00004462- Patch #1675423: PyComplex_AsCComplex() now tries to convert an
4463 object to complex using its __complex__() method before falling back
4464 to the __float__() method. Therefore, the functions in the cmath
4465 module now can operate on objects that define a __complex__()
4466 method.
Georg Brandl2b869942007-03-17 16:08:45 +00004467
Georg Brandl3ee81df2008-05-17 18:14:43 +00004468- Patch #1623563: allow __class__ assignment for classes with
4469 __slots__. The old and the new class are still required to have the
4470 same slot names.
Žiga Seilnacht6f2d09c2007-03-16 11:59:38 +00004471
Georg Brandl3ee81df2008-05-17 18:14:43 +00004472- Patch #1642547: Fix an error/crash when encountering syntax errors

Georg Brandl3ee81df2008-05-17 18:14:43 +00004475- Patch #1462488: Python no longer segfaults when
4476 ``object.__reduce_ex__()`` is called with an object that is faking
4477 its type.
Žiga Seilnacht20f43d32007-03-15 11:44:55 +00004478
Georg Brandl3ee81df2008-05-17 18:14:43 +00004479- Patch #1680015: Don't modify __slots__ tuple if it contains an

4483
Georg Brandl7b9c5552007-03-12 14:30:05 +00004484- Bug #1678647: write a newline after printing an exception in any
4485 case, even when converting the value to a string failed.
4486
Georg Brandl871f1bc2007-03-12 13:17:36 +00004487- The dir() function has been extended to call the __dir__() method on
Georg Brandl3ee81df2008-05-17 18:14:43 +00004488 its argument, if it exists. If not, it will work like before. This
4489 allows customizing the output of dir() in the presence of a
4490 __getattr__().
Georg Brandl871f1bc2007-03-12 13:17:36 +00004491
Collin Winter276887b2007-03-12 16:11:39 +00004492- Patch #922167: Python no longer segfaults when faced with infinitely
4493 self-recursive reload() calls (as reported by bug #742342).
4494
Georg Brandl3ee81df2008-05-17 18:14:43 +00004495- Patch #1675981: remove unreachable code from ``type.__new__()``

Georg Brandl3ee81df2008-05-17 18:14:43 +00004498- Patch #1491866: change the complex() constructor to allow
4499 parthensized forms. This means complex(repr(x)) now works instead of
4500 raising a ValueError.
Collin Wintere38051d2007-03-09 20:33:07 +00004501
Georg Brandlaa2321b2007-03-07 00:40:28 +00004502- Patch #703779: unset __file__ in __main__ after running a file. This
Georg Brandl3ee81df2008-05-17 18:14:43 +00004503 makes the filenames the warning module prints much more sensible
4504 when a PYTHONSTARTUP file is used.
Georg Brandlaa2321b2007-03-07 00:40:28 +00004505
Georg Brandl49aafc92007-03-07 00:34:46 +00004506- Variant of patch #697613: don't exit the interpreter on a SystemExit
4507 exception if the -i command line option or PYTHONINSPECT environment
Georg Brandl3ee81df2008-05-17 18:14:43 +00004508 variable is given, but break into the interactive interpreter just
4509 like on other exceptions or normal program exit.

Georg Brandl0fca97a2007-03-05 22:28:08 +00004517- Patch #1674228: when assigning a slice (old-style), check for the
4518 sq_ass_slice instead of the sq_slice slot.
4519
Georg Brandl3ee81df2008-05-17 18:14:43 +00004520- When printing an unraisable error, don't print exceptions. before
4521 the name. This duplicates the behavior whening normally printing
4522 exceptions.
Neal Norwitz88516a62007-02-26 22:41:45 +00004523
Georg Brandl3ee81df2008-05-17 18:14:43 +00004524- Bug #1653736: Properly discard third argument to

Facundo Batistab6a5c9d2007-03-29 18:22:35 +00005024- Added a timeout parameter to the constructor of other protocols
5025 (telnetlib, ftplib, smtplib and poplib). This is second part of the
5026 work started with create_connection() and timeout in httplib, and
5027 closes patch #723312.
5028

Georg Brandl3ee81df2008-05-17 18:14:43 +00005055 AttributeError instead of an IOError when the server's response
5056 didn't contain a valid HTTP status line.
Georg Brandlf66b6032007-03-14 08:27:52 +00005057

Georg Brandl3ee81df2008-05-17 18:14:43 +00005062- Patch #1429539: pdb now correctly initializes the __main__ module
5063 for the debugged script, which means that imports from __main__ work
Georg Brandlb6ae6aa2007-03-13 21:58:44 +00005064 correctly now.
5065

Georg Brandl3ee81df2008-05-17 18:14:43 +00005073- Patch #1530482: add pydoc.render_doc() which returns the

5088
Georg Brandl92a6bae2007-03-13 17:43:32 +00005089- Patch #1603688: ConfigParser.SafeConfigParser now checks values that
Georg Brandl3ee81df2008-05-17 18:14:43 +00005090 are set for invalid interpolation sequences that would lead to
5091 errors on reading back those values.

5134 returned string up to the first NUL character.

5145
Georg Brandl3ee81df2008-05-17 18:14:43 +00005146- unittest now verifies more of its assumptions. In particular,
5147 TestCase and TestSuite subclasses (not instances) are no longer
5148 accepted in TestSuite.addTest(). This should cause no
5149 incompatibility since it never made sense with ordinary subclasses
5150 -- the failure just occurred later, with a more cumbersome
5151 exception.

Georg Brandl3ee81df2008-05-17 18:14:43 +00005540 time so that opening a database previously created with the DB_DUP
5541 or DB_DUPSORT flag set will keep the proper behavior on subsequent
5542 opens. Specifically: dictionary assignment to a DB object will
5543 replace all values for a given key when the database allows
5544 duplicate values. DB users should use DB.put(k, v) when they want
5545 to store duplicates; not DB[k] = v.

5552 characters with ASCII value less than 32. Also, it correctly quotes
5553 dots only if they occur on a single line, as opposed to the previous
5554 behavior of quoting dots if they are the second character of any
5555 line.
