Ezio Melottiab2eb0e2010-06-05 19:21:32 +000033- Issue #8271: during the decoding of an invalid UTF-8 byte sequence, only the
34 start byte and the continuation byte(s) are now considered invalid, instead
35 of the number of bytes specified by the start byte.
36 E.g.: '\xf1\x80AB'.decode('utf-8', 'replace') now returns u'\ufffdAB' and
37 replaces with U+FFFD only the start byte ('\xf1') and the continuation byte
38 ('\x80') even if '\xf1' is the start byte of a 4-bytes sequence.
39 Previous versions returned a single u'\ufffd'.

Mark Dickinson23f0d6b2010-06-05 11:52:24 +000041- Issue #8627: Remove bogus "Overriding __cmp__ blocks inheritance of
Mark Dickinsone4b83e02010-06-05 12:14:43 +000042 __hash__ in 3.x" warning. Also fix "XXX undetected error" that
43 arises from the "Overriding __eq__ blocks inheritance ..." warning
44 when turned into an exception: in this case the exception simply
45 gets ignored.
Mark Dickinson23f0d6b2010-06-05 11:52:24 +000046
Mark Dickinson4ca7c3c2010-05-30 13:18:10 +000047- Issue #8748: Fix two issues with comparisons between complex and integer
48 objects. (1) The comparison could incorrectly return True in some cases
49 (2**53+1 == complex(2**53) == 2**53), breaking transivity of equality.
50 (2) The comparison raised an OverflowError for large integers, leading
51 to unpredictable exceptions when combining integers and complex objects
52 in sets or dicts.
53
Mark Dickinson81336372010-05-30 12:12:25 +000054- Issue #5211: Implicit coercion for the complex type is now completely
55 removed. (Coercion for arithmetic operations was already removed in 2.7
56 alpha 4, but coercion for rich comparisons was accidentally left in.)
57
Victor Stinnerc49dfcc2010-05-25 22:30:32 +000058- Issue #3798: Write sys.exit() message to sys.stderr to use stderr encoding
59 and error handler, instead of writing to the C stderr file in utf-8
60
Georg Brandlfee0f442010-05-22 21:26:21 +000061- Issue #7902: When using explicit relative import syntax, don't try implicit
62 relative import semantics.
Brett Cannoneb3cd302010-05-20 18:37:55 +000063

Georg Brandlfee0f442010-05-22 21:26:21 +000073- Issue #5753: A new C API function, :cfunc:`PySys_SetArgvEx`, allows embedders
74 of the interpreter to set sys.argv without also modifying sys.path. This
75 helps fix `CVE-2008-5983

Georg Brandlfee0f442010-05-22 21:26:21 +0000191- Issue #1533: Fix inconsistency in range function argument processing: any
192 non-float non-integer argument is now converted to an integer (if possible)
193 using its __int__ method. Previously, only small arguments were treated this

Mark Dickinsond2f3e3f2010-05-05 22:23:58 +0000394 (Optimization was unintentionally turned on in gcc --with-pydebug builds in

418
Philip Jenveyaebbaeb2010-04-06 23:24:45 +0000419- Issue #7301: Add environment variable $PYTHONWARNINGS.
420
Benjamin Peterson3a1dfa22010-04-06 21:50:00 +0000421- Issue #8329: Don't return the same lists from select.select when no fds are
422 changed.
423
Georg Brandlfee0f442010-05-22 21:26:21 +0000424- Issue #8259: ``1L << (2**31)`` no longer produces an 'outrageous shift error'
Mark Dickinson82791672010-04-06 16:47:55 +0000425 on 64-bit machines. The shift count for either left or right shift is
426 permitted to be up to sys.maxsize.
427
Benjamin Peterson4ceeeb02010-04-03 22:48:51 +0000428- Ensure that tokenization of identifiers is not affected by locale.

433
Georg Brandlfee0f442010-05-22 21:26:21 +0000434- Issue #7994: Issue a PendingDeprecationWarning if object.__format__ is called
435 with a non-empty format string. This is an effort to future-proof user
436 code. If a derived class does not currently implement __format__ but later
437 adds its own __format__, it would most likely break user code that had
438 supplied a format string. This will be changed to a DeprecationWaring in
439 Python 3.3 and it will be an error in Python 3.4.

477
Raymond Hettinger34c35b22010-04-03 10:22:00 +0000478- collections.Counter() now supports a subtract() method.
479
Georg Brandlfee0f442010-05-22 21:26:21 +0000480- The functools module now has a total_ordering() class decorator to simplify

Georg Brandlfee0f442010-05-22 21:26:21 +0000489- Issue #7279: Comparisons involving a Decimal signaling NaN now signal
490 InvalidOperation instead of returning False. (Comparisons involving a quiet
491 NaN are unchanged.) Also, Decimal quiet NaNs are now hashable; Decimal
492 signaling NaNs remain unhashable.

Georg Brandlfee0f442010-05-22 21:26:21 +0000494- Issue #2531: Comparison operations between floats and Decimal instances now
495 return a result based on the numeric values of the operands; previously they
496 returned an arbitrary result based on the relative ordering of id(float) and
497 id(Decimal).

Barry Warsawf7f2d6f2010-03-31 21:07:16 +0000499- Issue #8233: When run as a script, py_compile.py optionally takes a single
Georg Brandlfee0f442010-05-22 21:26:21 +0000500 argument `-` which tells it to read files to compile from stdin. Each line is
501 read on demand and the named file is compiled immediately. (Original patch by

Georg Brandlfee0f442010-05-22 21:26:21 +0000511- Comparisons using one of <, <=, >, >= between a complex instance and a
512 Fractions instance now raise TypeError instead of returning True/False. This
513 makes Fraction <=> complex comparisons consistent with int <=> complex, float
514 <=> complex, and complex <=> complex comparisons.

Antoine Pitrouf3fa0742010-01-31 22:26:04 +0000921- Issue #6939: Fix file I/O objects in the `io` module to keep the original
Georg Brandlba83f822010-03-14 09:50:54 +0000922 file position when calling `truncate()`. It would previously change the file
923 position to the given argument, which goes against the tradition of
Antoine Pitrouf3fa0742010-01-31 22:26:04 +0000924 ftruncate() and other truncation APIs. Patch by Pascal Chambon.

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

Georg Brandlba83f822010-03-14 09:50:54 +0000943- Issue #7748: Since unicode values are supported for some metadata options in

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

Benjamin Peterson4f51baf2009-12-05 18:40:02 +00001015What's New in Python 2.7 alpha 2?
1016=================================

1021-----------------
1022
Georg Brandlba83f822010-03-14 09:50:54 +00001023- The ``__complex__()`` method is now looked up on the class of instances to
1024 make it consistent with other special methods.
Benjamin Petersonecdae192010-01-04 00:43:01 +00001025
Antoine Pitrou5b7139a2010-01-02 21:12:58 +00001026- Issue #7462: Implement the stringlib fast search algorithm for the `rfind`,
1027 `rindex`, `rsplit` and `rpartition` methods. Patch by Florent Xicluna.
1028
Mark Dickinson1b34d252010-01-01 17:27:30 +00001029- Issue #5080: A number of functions and methods previously produced a
Georg Brandlba83f822010-03-14 09:50:54 +00001030 DeprecationWarning when passed a float argument where an integer was expected.
1031 These functions and methods now raise TypeError instead. The majority of the
1032 effects of this change are in the extension modules, but some core functions
1033 and methods are affected: notably the 'chr', 'range' and 'xrange' builtins,
1034 and many unicode/str methods.
Mark Dickinson1b34d252010-01-01 17:27:30 +00001035

Amaury Forgeot d'Arc8645a5c2009-12-29 22:03:38 +00001044- Issue #7413: Passing '\0' as the separator to datetime.datetime.isoformat()
1045 used to drop the time part of the result.
1046
Georg Brandlba83f822010-03-14 09:50:54 +00001047- Issue #1811: Improve accuracy and cross-platform consistency for true division
1048 of integers: the result of a/b is now correctly rounded for ints a and b (at
1049 least on IEEE 754 platforms), and in particular does not depend on the
1050 internal representation of a long.
Mark Dickinson46572832009-12-27 14:55:57 +00001051
Georg Brandlba83f822010-03-14 09:50:54 +00001052- Issue #6108: ``unicode(exception)`` and ``str(exception)`` should return the
1053 same message when only ``__str__()`` (and not ``__unicode__()``) is overridden
1054 in the subclass.
Ezio Melottif84caf42009-12-24 22:25:17 +00001055

Ronald Oussoren92919a62009-12-24 13:30:58 +00001057 executables on OSX.
1058
Georg Brandlba83f822010-03-14 09:50:54 +00001059 These executables now work properly with the arch(1) command: ``arch -ppc
1060 python`` will start a universal binary version of python in PPC mode (unlike
1061 previous releases).
Ronald Oussoren92919a62009-12-24 13:30:58 +00001062
Georg Brandlba83f822010-03-14 09:50:54 +00001063- Issue #1680159: Unicode coercion during an 'in' operation no longer masks the
1064 underlying error when the coercion fails for the left hand operand.

Antoine Pitrou80157252010-01-08 19:20:17 +00001083- Issue #7092: Remove py3k warning when importing cPickle. 2to3 handles
Georg Brandlba83f822010-03-14 09:50:54 +00001084 renaming of `cPickle` to `pickle`. The warning was annoying since there's no
1085 alternative to cPickle if you care about performance. Patch by Florent

1121 argument where file-like objects (ie StringIO and BytesIO) accept them to mean
1122 the same as passing no argument.
1123
Georg Brandlba83f822010-03-14 09:50:54 +00001124- Issue #7348: ``StringIO.StringIO.readline(-1)`` now acts as if it got no

Georg Brandlba83f822010-03-14 09:50:54 +00001217- Issue #7117: ``repr(x)`` for a float x returns a result based on the shortest
1218 decimal string that's guaranteed to round back to x under correct rounding
1219 (with round-half-to-even rounding mode). Previously it gave a string based on
1220 rounding x to 17 decimal digits. repr(x) for a complex number behaves
1221 similarly. On platforms where the correctly-rounded strtod and dtoa code is
1222 not supported (see below), repr is unchanged.
Mark Dickinsonb678de82009-11-19 18:41:49 +00001223
Georg Brandlba83f822010-03-14 09:50:54 +00001224- Issue #7117: On almost all platforms: float-to-string and string-to-float
1225 conversions within Python are now correctly rounded. Places these conversions
1226 occur include: str for floats and complex numbers; the float and complex
1227 constructors; old-style and new-style numeric formatting; serialization and
1228 deserialization of floats and complex numbers using marshal, pickle and json;
1229 parsing of float and imaginary literals in Python code; Decimal-to-float
1230 conversion.
Mark Dickinsonb678de82009-11-19 18:41:49 +00001231
Georg Brandlba83f822010-03-14 09:50:54 +00001232 The conversions use a Python-adapted version of David Gay's well-known dtoa.c,
1233 providing correctly-rounded strtod and dtoa C functions. This code is
1234 supported on Windows, and on Unix-like platforms using gcc, icc or suncc as
1235 the C compiler. There may be a small number of platforms on which correct
1236 operation of this code cannot be guaranteed, so the code is not used: notably,
1237 this applies to platforms where the C double format is not IEEE 754 binary64,
1238 and to platforms on x86 hardware where the x87 FPU is set to 64-bit precision
1239 and Python's configure script is unable to determine how to change the FPU
1240 precision. On these platforms conversions use the platform strtod and dtoa,
1241 as before.
Mark Dickinsonb678de82009-11-19 18:41:49 +00001242
Georg Brandlba83f822010-03-14 09:50:54 +00001243- Issue #7117: Backport round implementation from Python 3.x. ``round()`` now
1244 uses the correctly-rounded string <-> float conversions described above (when
1245 available), and so produces correctly rounded results that will display nicely
1246 under the float repr. There are two related small changes: (1) round now
1247 accepts any class with an ``__index__()`` method for its second argument (but
1248 no longer accepts floats for the second argument), and (2) an excessively

Amaury Forgeot d'Arc05e34492008-09-10 22:04:45 +00003033- Issue #3743: In a few places, PY_FORMAT_SIZE_T was incorrectly used with
3034 PyString_FromFormat or PyErr_Format to display size_t values. The macro
3035 PY_FORMAT_SIZE_T is designed to select the correct format for the OS
3036 ``printf`` function, whereas PyString_FromFormat has an independent
3037 implementation and uses "%zd" on all platforms for size_t values.
3038 This makes a difference on win64, where ``printf`` needs "%Id" to display
3039 64bit values.

Antoine Pitrou0668c622008-08-26 22:42:08 +00003059 match Python 2.5 speed despite the __instancecheck__ / __subclasscheck__

3063 type object.

3134 warnings.catch_warnings() along with some API cleanup. Expanding the tests
3135 for catch_warnings() also led to an improvement in the raising of a
3136 DeprecationWarning related to warnings.warn_explicit().

Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00003202What's New in Python 2.6 beta 3?
3203================================
3204
Barry Warsaw07a4a382008-08-21 01:15:08 +00003205*Release date: 20-Aug-2008*
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00003206
3207Core and Builtins
3208-----------------
3209
Guido van Rossumf8402962008-08-20 15:01:50 +00003210- Issue #1878: Remove Py_TPFLAGS_HAVE_VERSION_TAG from
3211 Py_TPFLAGS_DEFAULT when not building the core. This means 3rd party
3212 extensions do not automatically benefit from the class attribute
3213 cache; they will have to explicitly add Py_TPFLAGS_HAVE_VERSION_TAG
3214 to their tp_flags field if they care. This is a backwards
3215 compatibility feature; in 3.0, all types will use the cache by
3216 default.
3217
Benjamin Petersonf647dc12008-08-20 01:27:30 +00003218- Keyword arguments can now follow starred arguments. (``f(a, *args,
3219 keyword=23)`` is now valid syntax.)
3220
Thomas Heller0ad5ae02008-08-19 19:25:04 +00003221- ctypes function pointers that are COM methods have a boolean True
3222 value again.
3223
Martin v. Löwisf91d46a2008-08-12 14:49:50 +00003224- Issue #3139: Make buffer-interface thread-safe wrt. PyArg_ParseTuple,
3225 by denying s# to parse objects that have a releasebuffer procedure,
3226 and introducing s*.
3227
Georg Brandl1e13ea92008-08-11 09:07:59 +00003228- Issue #3537: Fix an assertion failure when an empty but presized dict
3229 object was stored in the freelist.
3230
Mark Dickinsonb6467572008-08-04 21:30:09 +00003231- Issue #1481296: Make long(float('nan')) and int(float('nan')) raise
3232 ValueError consistently across platforms.
3233
Amaury Forgeot d'Arc39fd6722008-07-31 21:28:03 +00003234- Issue #3479: On platforms where sizeof(int) is smaller than sizeof(long)
3235 (64bit Unix, for example), unichr() would truncate its argument and return
3236 u'\x00' for unichr(2**32). Now it properly raises an OverflowError.
3237
Neal Norwitze7d8be82008-07-31 17:17:14 +00003238- Apply security patches from Apple.
3239
Amaury Forgeot d'Arc246daed2008-07-31 00:42:16 +00003240- Issue #2542: Now that issubclass() may call arbitrary code, ensure that
3241 PyErr_ExceptionMatches returns 0 when an exception occurs there.
3242
Antoine Pitrou92f82162008-07-25 22:22:08 +00003243- Issue #1819: function calls with several named parameters are now on
3244 average 35% faster (as measured by pybench).
3245
Amaury Forgeot d'Arce4921fe2008-07-21 22:00:38 +00003246- Issue #2378: An unexpected UnboundLocalError or NameError could appear when
3247 the python debugger steps into a class statement: the free variables (local
3248 variables defined in an outer scope) would be deleted from the outer scope.
3249
Gregory P. Smith0470bab2008-07-22 04:46:32 +00003250- Issue #2620: Overflow checking when allocating or reallocating memory
3251 was not always being done properly in some python types and extension
3252 modules. PyMem_MALLOC, PyMem_REALLOC, PyMem_NEW and PyMem_RESIZE have
3253 all been updated to perform better checks and places in the code that
3254 would previously leak memory on the error path when such an allocation
3255 failed have been fixed.
3256
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00003257Library
3258-------
3259
Hirokazu Yamamoto838c79f2008-08-20 13:14:07 +00003260- Issue #3612: Added some missing basic types in ctypes.wintypes.
3261
Benjamin Petersone977ad42008-08-20 01:42:01 +00003262- The methods ``is_in_tuple()``, ``is_vararg()``, and ``is_keywordarg()`` of
3263 symtable.Symbol have been deprecated for removal in 3.0 and the next release.
3264
Amaury Forgeot d'Arc351ffb82008-08-18 19:23:47 +00003265- Issue #2234: distutils failed for some versions of the cygwin compiler. The
3266 version reported by these tools does not necessarily follow the python
3267 version numbering scheme, so the module is less strict when parsing it.
3268
Nick Coghlanf70385a2008-08-18 12:42:46 +00003269- Issue #2235: Added Py3k warnings for types which will become unhashable
3270 under the stricter __hash__ inheritance rules in 3.0. Several types
3271 which did not meet the rules for hash invariants and were already
3272 unhashable in 3.0 have now been explicitly flagged as unhashable in
3273 2.6 as well (collections.Mapping, collections.Set, unittest.TestSuite,
3274 xml.dom.minidom.NamedNodeMap, numbers.Number, UserList.UserList)
3275
Brett Cannon88f801d2008-08-18 00:46:22 +00003276- Update __all__ for cookielib, csv, os, urllib2, and weakref to include things

3280
Brett Cannon46225e72008-08-18 00:36:52 +00003281- Remove unneeded imports of 'sys' and 'warnings' from 'io'.

3284
Hirokazu Yamamoto41a81eb2008-08-17 13:10:46 +00003285- Issue #3575: Incremental decoder's decode function now takes bytearray
3286 by using 's*' instead of 't#'.
3287
Mark Dickinson3e4caeb2009-02-21 20:27:01 +00003288- Issue #2222: Fixed reference leak when occurred os.rename()
Hirokazu Yamamoto7f30a682008-08-17 09:46:56 +00003289 fails unicode conversion on 2nd parameter. (windows only)
3290
Facundo Batista94f243a2008-08-17 03:38:39 +00003291- Issue 2464. urllib2 now supports a malformation in the URL received
3292 in a redirect.
3293
Brett Cannonabe423e2008-08-16 21:47:07 +00003294- Silence the DeprecationWarning raised when importing mimetools in
Brett Cannon721b1452008-08-16 22:00:27 +00003295 BaseHTTPServer, cgi (and rfc822), httplib.
Brett Cannonabe423e2008-08-16 21:47:07 +00003296
Facundo Batistaeb90b782008-08-16 14:44:07 +00003297- Issue #2776: fixed small issue when handling an URL with double slash
3298 after a 302 response in the case of not going through a proxy.
3299
Antoine Pitroub90a8be2008-08-15 21:03:21 +00003300- Issue #2676: in the email package, content-type parsing was hanging on
3301 pathological input because of quadratic or exponential behaviour of a
3302 regular expression.
3303
Antoine Pitrou11ec65d2008-08-14 21:04:30 +00003304- Issue #3476: binary buffered reading through the new "io" library is now
3305 thread-safe.
3306
Brett Cannonbf3157b2008-08-14 05:00:03 +00003307- Silence the DeprecationWarning of rfc822 when it is imported by mimetools
3308 since mimetools itself is deprecated. Because modules are cached, all
3309 subsequent imports of rfc822 will not raise a visible DeprecationWarning.
3310
Antoine Pitrou9fcd4b32008-08-11 17:21:36 +00003311- Issue #3134: shutil referenced undefined WindowsError symbol.
3312
Robert Schuppenies14646332008-08-10 11:01:53 +00003313- Issue #1342811: Fix leak in Tkinter.Menu.delete. Commands associated to
3314 menu entries were not deleted.
3315
Brett Cannon83e81842008-08-09 23:30:55 +00003316- Copied the implementation of reduce() to _functools.reduce() to have a
3317 version that did not raise a DeprecationWarning under -3.
3318
Antoine Pitrou76b8bee2008-08-09 17:27:23 +00003319- Issue #3205: When iterating over a BZ2File fails allocating memory, raise
3320 a MemoryError rather than silently stop the iteration.
3321
Guido van Rossum59ce9012008-08-09 14:55:34 +00003322- Issue #3487: sre "bytecode" validator. Passing invalid "re-bytecode"
3323 to _sre.compile() will now be rejected. This should not affect anybody
3324 since the re.compile() function never generates invalid re-bytecode.
3325
Skip Montanaroa032bf42008-08-08 22:52:51 +00003326- Issue #3436: Make csv.DictReader's fieldnames attribute a property so that

Brett Cannon3aa2a492008-08-06 22:28:09 +00003330- Issue #2338: Create imp.reload() to help with transitioning to Python 3.0 as
3331 the reload() built-in has been removed.
3332
Brett Cannon7e30b672008-08-04 21:52:25 +00003333- Changed code in the following modules/packages to remove warnings raised
Brett Cannonc1b76e42008-08-09 23:06:16 +00003334 while running under the ``-3`` flag: aifc, asynchat, asyncore, bdb, bsddb,

Antoine Pitroude781a42008-08-09 12:43:23 +00003345 asking for a specific length. This problem only affected files opened
3346 using the new "io" module, not the built-in open() function.

3373 mode 0600 rather than 000 under Unix.
3374
Gregory P. Smitha36f8fe2008-08-04 00:13:29 +00003375- Issue #1857: subprocess.Popen.poll gained an additional _deadstate keyword

Mark Dickinson64b7e502008-07-16 09:40:03 +00003408- Issue #3360: Fix incorrect parsing of '020000000000.0', which
3409 produced a ValueError instead of giving the correct float.
3410
Eric Smitha5fa5a22008-07-16 00:11:49 +00003411- Issue #3083: Add alternate (#) formatting for bin, oct, hex output
3412 for str.format(). This adds the prefix 0b, 0o, or 0x, respectively.
3413
Mark Dickinson7103aa42008-07-15 19:08:33 +00003414- Issue #3008: the float type has a new instance method 'float.hex'
3415 and a new class method 'float.fromhex' to convert floating-point
3416 numbers to and from hexadecimal strings, respectively.
3417
Nick Coghlan6d6bd442008-07-15 15:40:22 +00003418- Issue #2235: __hash__ is once again inherited by default. To allow
3419 collections.Hashable to remain meaningful in the presence of the
3420 default hash implementation (object.__hash__), it is now possible
3421 to explicit block inheritance of hash by setting __hash__=None at
3422 the Python level, or tp_hash=PyObject_HashNotImplemented at the C
3423 level.
3424
Nick Coghlanb028f502008-07-13 14:52:36 +00003425- Issue #3221: Issue a RuntimeWarning instead of raising SystemError if
3426 the parent module cannot be found while performing an absolute import.
3427 This means that an incorrectly defined __package__ attribute will
3428 now only prevent relative imports in that module rather than causing
3429 all imports from that module to fail.
3430
Nick Coghlan14ff9942008-07-08 14:21:42 +00003431- Issue #2517: Allow unicode messages in Exceptions again by correctly

3441 another thread's dictionary.
3442
Mark Dickinson1ec2fcd2008-06-20 14:53:43 +00003443- Issue #3004: Minor change to slice.indices(): the start and stop
3444 arguments are now treated identically, making the behaviour easier
3445 to describe and understand. For example, slice(None, -10,
3446 1).indices(9) now returns (0, 0, 1) instead of (0, -1, 1), and
3447 slice(None, 10, -1).indices(10) returns (9, 9, -1) instead of (9,
3448 10, -1).

Georg Brandl278fc502008-07-19 12:46:12 +00003450- Issue #3219: Calling a function with repeated keyword arguments,
3451 f(a=2, a=23), would not cause a syntax error. This was a regression
3452 from 2.4 caused by the switch to the new compiler.

3491 both unnecessary (HTTP allows text content to be sent in several forms) and
Andrew M. Kuchlingcc3f2b12008-07-10 14:43:31 +00003492 wrong because the actual transmitted size could differ from the

Georg Brandl3ee81df2008-05-17 18:14:43 +00003964- Issue #1631171: Re-implement the 'warnings' module in C (the
3965 original Python code has been kept as backup). This will allow for
3966 using the 'warning's machinery in such places as the parser where
3967 use of pure Python code is not possible. Both the ``showarning()``
3968 and ``formatwarning()`` gain an optional 'line' argument which is
3969 not called by default for backwards-compatibility reasons. Setting
3970 ``warnings.showwarning()`` to an implementation that lacks support
3971 for the ``line`` argument will raise a DeprecationWarning.

Georg Brandl3ee81df2008-05-17 18:14:43 +00004034- Issue #2550: The approach used by client/server code for obtaining
4035 ports to listen on in network-oriented tests has been refined in an
4036 effort to facilitate running multiple instances of the entire
4037 regression test suite in parallel without issue.
4038 test_support.bind_port() has been fixed such that it will always
4039 return a unique port -- which wasn't always the case with the
4040 previous implementation, especially if socket options had been set
4041 that affected address reuse (i.e. SO_REUSEADDR, SO_REUSEPORT). The
4042 new implementation of bind_port() will actually raise an exception
4043 if it is passed an AF_INET/SOCK_STREAM socket with either the
4044 SO_REUSEADDR or SO_REUSEPORT socket option set. Furthermore, if
4045 available, bind_port() will set the SO_EXCLUSIVEADDRUSE option on
4046 the socket it's been passed. This currently only applies to
4047 Windows. This option prevents any other sockets from binding to the
4048 host/port we've bound to, thus removing the possibility of the
4049 'non-deterministic' behaviour, as Microsoft puts it, that occurs
4050 when a second SOCK_STREAM socket binds and accepts to a host/port
4051 that's already been bound by another socket. The optional preferred
4052 port parameter to bind_port() has been removed. Under no
4053 circumstances should tests be hard coding ports!
4054
4055 test_support.find_unused_port() has also been introduced, which will
4056 pass a temporary socket object to bind_port() in order to obtain an
4057 unused port. The temporary socket object is then closed and
4058 deleted, and the port is returned. This method should only be used
4059 for obtaining an unused port in order to pass to an external program
4060 (i.e. the -accept [port] argument to openssl's s_server mode) or as
4061 a parameter to a server-oriented class that doesn't give you direct
4062 access to the underlying socket used.
4063
4064 Finally, test_support.HOST has been introduced, which should be used
4065 for the host argument of any relevant socket calls (i.e. bind and
4066 connect).
Trent Nelsone41b0062008-04-08 23:47:30 +00004067
4068 The following tests were updated to following the new conventions:
Georg Brandl3ee81df2008-05-17 18:14:43 +00004069 test_socket, test_smtplib, test_asyncore, test_ssl, test_httplib,
Trent Nelsone41b0062008-04-08 23:47:30 +00004070 test_poplib, test_ftplib, test_telnetlib, test_socketserver,
4071 test_asynchat and test_socket_ssl.
4072
Georg Brandl3ee81df2008-05-17 18:14:43 +00004073 It is now possible for multiple instances of the regression test
4074 suite to run in parallel without issue.

4341-----------------
4342
Fred Drakea8ee94b2008-03-01 02:45:07 +00004343- Issue #2051: pyc and pyo files are no longer created with permission
Barry Warsaw52973612008-03-01 02:23:38 +00004344 644. The mode is now inherited from the py file.

Georg Brandlad61bc82008-02-23 15:11:18 +00004346- Issue #2067: file.__exit__() now calls subclasses' close() method.
4347
4348- Patch #1759: Backport of PEP 3129 class decorators.
Christian Heimes5224d282008-02-23 15:01:05 +00004349
Vinay Sajipb7edfc42008-04-02 21:10:23 +00004350- Issue #1881: An internal parser limit has been increased. Also see
Facundo Batistafc2d0102008-02-23 12:01:13 +00004351 issue 215555 for a discussion.
4352
Eric Smitha73fbe72008-02-23 03:09:44 +00004353- Added the future_builtins module, which contains hex() and oct().
4354 These are the PEP 3127 version of these functions, designed to be
4355 compatible with the hex() and oct() builtins from Python 3.0. They
4356 differ slightly in their output formats from the existing, unchanged
4357 Python 2.6 builtins. The expected usage of the future_builtins
4358 module is:
4359 from future_builtins import hex, oct
4360
Eric Smith7ef40bf2008-02-20 23:34:22 +00004361- Issue #1600: Modifed PyOS_ascii_formatd to use at most 2 digit
4362 exponents for exponents with absolute value < 100. Follows C99
4363 standard. This is a change on Windows, which would use 3 digits.
4364 Also, added 'n' to the formats that PyOS_ascii_formatd understands,
4365 so that any alterations it does to the resulting string will be
4366 available in stringlib/formatter.h (for float.__format__).
4367
Eric Smith5a3c1352008-02-19 13:21:56 +00004368- Implemented PEP 3101, Advanced String Formatting. This adds a new
4369 builtin format(); a format() method for str and unicode; a
4370 __format__() method to object, str, unicode, int, long, float, and
4371 datetime; the class string.Formatter; and the C API
4372 PyObject_Format().
4373
Georg Brandl3ee81df2008-05-17 18:14:43 +00004374- Fixed several potential crashes, all caused by specially crafted
4375 __del__ methods exploiting objects in temporarily inconsistent
4376 state.
Amaury Forgeot d'Arc632fad32008-02-16 20:55:24 +00004377
Vinay Sajipb7edfc42008-04-02 21:10:23 +00004378- Issue #2115: Important speedup in setting __slot__ attributes. Also
Georg Brandl3ee81df2008-05-17 18:14:43 +00004379 prevent a possible crash: an Abstract Base Class would try to access
4380 a slot on a registered virtual subclass.
Amaury Forgeot d'Arc60d6c7f2008-02-15 21:22:45 +00004381
Georg Brandl3ee81df2008-05-17 18:14:43 +00004382- Fixed repr() and str() of complex numbers with infinity or nan as
4383 real or imaginary part.
Christian Heimes2f0da532008-02-15 06:57:08 +00004384
Georg Brandl3ee81df2008-05-17 18:14:43 +00004385- Clear all free lists during a gc.collect() of the highest generation
4386 in order to allow pymalloc to free more arenas. Python may give back
4387 memory to the OS earlier.
Christian Heimes3b718a72008-02-14 12:47:33 +00004388
Georg Brandl3ee81df2008-05-17 18:14:43 +00004389- Issue #2045: Fix an infinite recursion triggered when printing a
4390 subclass of collections.defaultdict, if its default_factory is set
4391 to a bound method.
Amaury Forgeot d'Arcb01aa432008-02-08 00:56:02 +00004392
Christian Heimesf75dbef2008-02-08 00:11:31 +00004393- Fixed a minor memory leak in dictobject.c. The content of the free
4394 list was not freed on interpreter shutdown.
4395
Georg Brandl21e99f42010-03-07 15:23:59 +00004396- Limit free list of method and built-in function objects to 256
Georg Brandl3ee81df2008-05-17 18:14:43 +00004397 entries each.
Christian Heimes6075a822008-02-06 12:44:34 +00004398
Georg Brandl3ee81df2008-05-17 18:14:43 +00004399- Patch #1953: Added ``sys._compact_freelists()`` and the C API
4400 functions ``PyInt_CompactFreeList`` and ``PyFloat_CompactFreeList``
Christian Heimes422051a2008-02-04 18:00:12 +00004401 to compact the internal free lists of pre-allocted ints and floats.
4402
Georg Brandl3ee81df2008-05-17 18:14:43 +00004403- Issue #1983: Fixed return type of fork(), fork1() and forkpty()
4404 calls. Python expected the return type int but the fork familie
4405 returns pi_t.
Christian Heimes951cc0f2008-01-31 23:08:23 +00004406
Georg Brandl3ee81df2008-05-17 18:14:43 +00004407- Issue #1678380: Fix a bug that identifies 0j and -0j when they

Georg Brandl3ee81df2008-05-17 18:14:43 +00004416- Added ``PyType_ClearCache()`` and ``sys._clear_type_cache`` to clear
4417 the internal lookup cache for ref leak tests.
Christian Heimes908caac2008-01-27 23:34:59 +00004418
Georg Brandl3ee81df2008-05-17 18:14:43 +00004419- Patch #1473257: generator objects gain a gi_code attribute. This is
4420 the same object as the func_code attribute of the function that
4421 produced the generator.
Georg Brandl0cdf9a32008-01-26 14:14:20 +00004422
Georg Brandl3ee81df2008-05-17 18:14:43 +00004423- Issue #1920: "while 0" statements were completely removed by the
4424 compiler, even in the presence of an "else" clause, which is
4425 supposed to be run when the condition is false. Now the compiler
4426 correctly emits bytecode for the "else" suite.
Amaury Forgeot d'Arc31eaafe2008-01-24 22:59:25 +00004427
Guido van Rossumeead05f2008-01-24 18:21:02 +00004428- A few crashers fixed: weakref_in_del.py (issue #1377858);
4429 loosing_dict_ref.py (issue #1303614, test67.py);
4430 borrowed_ref_[34].py (not in tracker).
4431
Vinay Sajipd7cf32e2008-01-24 12:43:33 +00004432- Issue #1069410: The "can't load dll" message box on Windows is
Christian Heimesb2302ba2008-01-23 17:15:06 +00004433 suppressed while an extension is loaded by calling SetErrorMode in
4434 dynload_win.c. The error is still reported properly.
4435
Georg Brandl3ee81df2008-05-17 18:14:43 +00004436- Issue #1915: Python compiles with --enable-unicode=no again. However
Christian Heimes082c9b02008-01-23 14:20:50 +00004437 several extension methods and modules do not work without unicode
4438 support.
4439
Georg Brandl26543b12008-01-21 18:36:51 +00004440- Issue #1882: when compiling code from a string, encoding cookies in the
4441 second line of code were not always recognized correctly.
4442
Georg Brandl14404b62008-01-19 19:27:05 +00004443- Issue #1679: "0x" was taken as a valid integer literal.
4444
Georg Brandl6caad7d2008-01-26 14:19:22 +00004445- Issue #1865: ``bytes`` as an alias for ``str`` and b"" as an alias "" were
Christian Heimes288e89a2008-01-18 18:24:07 +00004446 added.
4447
Christian Heimesc94e2b52008-01-14 04:13:37 +00004448- sys.float_info / PyFloat_GetInfo: The floating point information
4449 object was converted from a dict to a specialized structseq object.
4450
Georg Brandl3ee81df2008-05-17 18:14:43 +00004451- Patch #1816: Added sys.flags structseq. It exposes the status of
4452 most command line arguments and PYTHON* environment variables.
Christian Heimesf31b69f2008-01-14 03:42:48 +00004453
Georg Brandl3ee81df2008-05-17 18:14:43 +00004454- Objects/structseq.c: Implemented new structseq representation. The
4455 patch makes structseqs (e.g. the return value of os.stat) more
4456 readable.
Christian Heimes9c201962008-01-14 03:33:52 +00004457
Georg Brandl3ee81df2008-05-17 18:14:43 +00004458- Patch #1700288: added a type attribute cache that caches method

4467 envvar and sys.dont_write_bytecode attribute. All these can be set
4468 to forbid Python to attempt to write compiled bytecode files.
Georg Brandl2da0fce2008-01-07 17:09:35 +00004469
Georg Brandl3ee81df2008-05-17 18:14:43 +00004470- Improve some exception messages when Windows fails to load an
4471 extension module. Now we get for example '%1 is not a valid Win32
4472 application' instead of 'error code 193'.
Amaury Forgeot d'Arce0b76952008-01-04 02:04:15 +00004473

Georg Brandl3ee81df2008-05-17 18:14:43 +00004480 and INF. float("nan"), float("inf") and float("-inf") now work on
4481 every platform with IEEE 754 semantics.

Georg Brandl3ee81df2008-05-17 18:14:43 +00004483- Compiler now generates simpler and faster code for dictionary
4484 literals. The oparg for BUILD_MAP now indicates an estimated
4485 dictionary size. There is a new opcode, STORE_MAP, for adding
4486 entries to the dictionary.

Georg Brandl21e99f42010-03-07 15:23:59 +00004530- The enumerate() built-in function is no longer bounded to sequences
Georg Brandl3ee81df2008-05-17 18:14:43 +00004531 smaller than LONG_MAX. Formerly, it raised an OverflowError. Now,
4532 automatically shifts from ints to longs.
Raymond Hettinger8f669372007-10-03 21:18:11 +00004533
Georg Brandl3ee81df2008-05-17 18:14:43 +00004534- Issue #1686386: Tuple's tp_repr did not take into account the
4535 possibility of having a self-referential tuple, which is possible
4536 from C code. Nor did object's tp_str consider that a type's tp_str
4537 could do something that could lead to an inifinite recursion.
4538 Py_ReprEnter() and Py_EnterRecursiveCall(), respectively, fixed the
4539 issues.

Georg Brandl3ee81df2008-05-17 18:14:43 +00004541- Issue #1164: It was possible to trigger deadlock when using the
4542 'print' statement to write to a file since the GIL was not released
4543 as needed. Now PyObject_Print() does the right thing along with
4544 various tp_print implementations of the built-in types and those in
4545 the collections module.

Brett Cannon1e534b52007-09-07 04:18:30 +00004554- Issue #1202533: Fix infinite recursion calls triggered by calls to
Georg Brandl3ee81df2008-05-17 18:14:43 +00004555 PyObject_Call() never calling back out to Python code to trigger
4556 recursion depth updates/checks. Required the creation of a static
4557 RuntimeError instance in case normalizing an exception put the
4558 recursion check value past its limit. Fixes crashers

Neal Norwitz0ac60192007-05-27 04:08:54 +00004574- Add new attribute names for function objects. All the func_* become
Georg Brandl3ee81df2008-05-17 18:14:43 +00004575 __*__ attributes. (Some already existed, e.g., __doc__ and
4576 __name__.)

4582 calls.
4583
Collin Winter62903052007-05-18 23:11:24 +00004584- except clauses may now be spelled either "except E, target:" or
Georg Brandl3ee81df2008-05-17 18:14:43 +00004585 "except E as target:". This is to provide forwards compatibility
4586 with Python 3.0.

Vinay Sajip8549ce32007-05-06 17:53:37 +00004593- When __slots__ are set to a unicode string, make it work the same as
Neal Norwitzcbd9ee62007-04-14 05:25:50 +00004594 setting a plain string, ie don't expand to single letter identifiers.
4595
Raymond Hettinger13936692007-04-11 18:40:58 +00004596- Request #1191699: Slices can now be pickled.

4600 remaining characters.
4601
Georg Brandl5cb76c12007-03-21 09:00:39 +00004602- Patch #1682205: a TypeError while unpacking an iterable is no longer

4606
Guido van Rossum143b5642007-03-23 04:58:42 +00004607- Bug #1683368: The object.__init__() and object.__new__() methods are
4608 now stricter in rejecting excess arguments. The only time when
4609 either allows excess arguments is when it is not overridden and the
4610 other one is. For backwards compatibility, when both are
4611 overridden, it is a deprecation warning (for now; maybe a Py3k
Guido van Rossum234b1ff2007-03-23 19:39:01 +00004612 warning later). Also, type.__init__() insists on the same signature
4613 as supported by type.__new__().
Guido van Rossum143b5642007-03-23 04:58:42 +00004614
Georg Brandl3ee81df2008-05-17 18:14:43 +00004615- Patch #1675423: PyComplex_AsCComplex() now tries to convert an
4616 object to complex using its __complex__() method before falling back
4617 to the __float__() method. Therefore, the functions in the cmath
4618 module now can operate on objects that define a __complex__()
4619 method.

4623 same slot names.

4636
Georg Brandl7b9c5552007-03-12 14:30:05 +00004637- Bug #1678647: write a newline after printing an exception in any
4638 case, even when converting the value to a string failed.
4639
Georg Brandl871f1bc2007-03-12 13:17:36 +00004640- The dir() function has been extended to call the __dir__() method on
Georg Brandl3ee81df2008-05-17 18:14:43 +00004641 its argument, if it exists. If not, it will work like before. This
4642 allows customizing the output of dir() in the presence of a
4643 __getattr__().

4652 parthensized forms. This means complex(repr(x)) now works instead of
4653 raising a ValueError.
Collin Wintere38051d2007-03-09 20:33:07 +00004654
Georg Brandlaa2321b2007-03-07 00:40:28 +00004655- Patch #703779: unset __file__ in __main__ after running a file. This
Georg Brandl3ee81df2008-05-17 18:14:43 +00004656 makes the filenames the warning module prints much more sensible
4657 when a PYTHONSTARTUP file is used.

Georg Brandl0fca97a2007-03-05 22:28:08 +00004670- Patch #1674228: when assigning a slice (old-style), check for the
4671 sq_ass_slice instead of the sq_slice slot.
4672
Georg Brandl3ee81df2008-05-17 18:14:43 +00004673- When printing an unraisable error, don't print exceptions. before

Georg Brandl3ee81df2008-05-17 18:14:43 +00005226- Patch #1530482: add pydoc.render_doc() which returns the

Georg Brandl3ee81df2008-05-17 18:14:43 +00005243 are set for invalid interpolation sequences that would lead to

5300 TestCase and TestSuite subclasses (not instances) are no longer
5301 accepted in TestSuite.addTest(). This should cause no

5303 -- the failure just occurred later, with a more cumbersome
5304 exception.

Gregory P. Smithbde4ae42008-01-17 08:35:49 +00005591 that the SMTP.starttls() caller no longer needs to call ehlo()

Gregory P. Smithec10a4a2007-11-05 02:32:26 +00005692- pybsddb.sf.net Bug #477182: Load the database flags at database open
Georg Brandl3ee81df2008-05-17 18:14:43 +00005693 time so that opening a database previously created with the DB_DUP
5694 or DB_DUPSORT flag set will keep the proper behavior on subsequent
5695 opens. Specifically: dictionary assignment to a DB object will
5696 replace all values for a given key when the database allows
5697 duplicate values. DB users should use DB.put(k, v) when they want
5698 to store duplicates; not DB[k] = v.

Georg Brandl3ee81df2008-05-17 18:14:43 +00005978 periodic threadstate and signal checking in tight loops. By
5979 default, this option is turned-off. It should only be enabled in

Georg Brandl3ee81df2008-05-17 18:14:43 +00006038- ``PySet_Add()`` can now modify a newly created frozenset. Similarly
6039 to ``PyTuple_SetItem``, it can be used to populate a brand new

6052
Georg Brandl3ee81df2008-05-17 18:14:43 +00006053- Issue #1521: On 64bit platforms, using PyArgs_ParseTuple with the t#
6054 of w# format code incorrectly truncated the length to an int, even
6055 when PY_SSIZE_T_CLEAN is set. The str.decode method used to return
6056 incorrect results with huge strings.

Georg Brandl3ee81df2008-05-17 18:14:43 +00006086- Added case insensitive comparison methods ``PyOS_stricmp(char*,
6087 char*)`` and ``PyOS_strnicmp(char*, char*, Py_ssize_t)``.
