Eric Smithee931b72010-01-27 00:28:29 +000015- Issue #7766: Change sys.getwindowsversion() return value to a named
16 tuple and add the additional members returned in an OSVERSIONINFOEX
17 structure. The new members are service_pack_major, service_pack_minor,
18 suite_mask, and product_type.
19
Antoine Pitroue80a6a42010-01-17 12:26:20 +000020- Issue #7561: Operations on empty bytearrays (such as `int(bytearray())`)
21 could crash in many places because of the PyByteArray_AS_STRING() macro
22 returning NULL. The macro now returns a statically allocated empty
23 string instead.
24
Antoine Pitrou64672132010-01-13 07:55:48 +000025- Issue #7622: Improve the split(), rsplit(), splitlines() and replace()
26 methods of bytes, bytearray and unicode objects by using a common
27 implementation based on stringlib's fast search. Patch by Florent Xicluna.

Mark Dickinson476279f2010-01-16 10:44:00 +000029- Issue #7632: Fix various str -> float conversion bugs present in 2.7
30 alpha 2, including: (1) a serious 'wrong output' bug that could
31 occur for long (> 40 digit) input strings, (2) a crash in dtoa.c
32 that occurred in debug builds when parsing certain long numeric
Mark Dickinson23df3d22010-01-17 13:37:57 +000033 strings corresponding to subnormal values, (3) a memory leak for
34 some values large enough to cause overflow, and (4) a number of
35 flaws that could lead to incorrectly rounded results.

51
Antoine Pitrou94c33eb2010-01-27 20:59:50 +000052- Issue #7610: Reworked implementation of the internal
53 :class:`zipfile.ZipExtFile` class used to represent files stored inside
54 an archive. The new implementation is significantly faster and can
55 be wrapped in a :class:`io.BufferedReader` object for more speedups.
56 It also solves an issue where interleaved calls to `read()` and
57 `readline()` give wrong results. Patch by Nir Aides.
58

68 encoded string for them. This ensure that the upload and register commands
69 send the right values to PyPI without any error.
70
R. David Murrayed44dfa2010-01-16 05:15:17 +000071- Issue #1670765: Prevent email.generator.Generator from re-wrapping

90
Tarek Ziadédc0f4872010-01-11 22:50:29 +000091- Issue #5372: Drop the reuse of .o files in Distutils' ccompiler (since

129Core and Builtins
130-----------------
131
Benjamin Petersonecdae192010-01-04 00:43:01 +0000132- The __complex__ method is now looked up on the class of instances to make it
133 consistent with other special methods.
134
Antoine Pitrou5b7139a2010-01-02 21:12:58 +0000135- Issue #7462: Implement the stringlib fast search algorithm for the `rfind`,
136 `rindex`, `rsplit` and `rpartition` methods. Patch by Florent Xicluna.
137
Mark Dickinson1b34d252010-01-01 17:27:30 +0000138- Issue #5080: A number of functions and methods previously produced a
139 DeprecationWarning when passed a float argument where an integer was
140 expected. These functions and methods now raise TypeError instead.
141 The majority of the effects of this change are in the extension
142 modules, but some core functions and methods are affected: notably
143 the 'chr', 'range' and 'xrange' builtins, and many unicode/str
144 methods.
145
Benjamin Peterson0f02d392009-12-30 19:34:10 +0000146- Issue #7604: Deleting an unset slotted attribute did not raise an

154
Amaury Forgeot d'Arc8645a5c2009-12-29 22:03:38 +0000155- Issue #7413: Passing '\0' as the separator to datetime.datetime.isoformat()
156 used to drop the time part of the result.
157
Mark Dickinson46572832009-12-27 14:55:57 +0000158- Issue #1811: improve accuracy and cross-platform consistency for
159 true division of integers: the result of a/b is now correctly
160 rounded for ints a and b (at least on IEEE 754 platforms), and in
161 particular does not depend on the internal representation of a long.
162
Ezio Melottif84caf42009-12-24 22:25:17 +0000163- Issue #6108: unicode(exception) and str(exception) should return the same
164 message when only __str__ (and not __unicode__) is overridden in the subclass.
165
Ronald Oussoren92919a62009-12-24 13:30:58 +0000166- Issue #6834: replace the implementation for the 'python' and 'pythonw'
167 executables on OSX.
168

170 ``arch -ppc python`` will start a universal binary version of python
171 in PPC mode (unlike previous releases).
172
R. David Murray0a0a1a82009-12-14 16:28:26 +0000173- Issue #1680159: unicode coercion during an 'in' operation no longer masks
174 the underlying error when the coercion fails for the left hand operand.
175
Benjamin Peterson4895af42009-12-13 16:36:53 +0000176- Issue #7491: Metaclass's __cmp__ method was ignored.
177
Antoine Pitrou2a08b422009-12-13 16:18:14 +0000178- Issue #7466: segmentation fault when the garbage collector is called

192 by Arfrever.
193
Antoine Pitrou80157252010-01-08 19:20:17 +0000194- Issue #7092: Remove py3k warning when importing cPickle. 2to3 handles

229
Benjamin Petersonddd392c2009-12-13 19:19:07 +0000230- Issue #7349: Make methods of file objects in the io module accept None as an
231 argument where file-like objects (ie StringIO and BytesIO) accept them to mean
232 the same as passing no argument.
233
Benjamin Petersonc4771d22009-12-13 17:31:31 +0000234- Issue #7348: StringIO.StringIO.readline(-1) now acts as if it got no argument

Mark Dickinson9dd5e162009-11-23 20:54:09 +0000312- Remove switch from "%f" formatting to "%g" formatting for floats
313 larger than 1e50 in absolute value.
314
Mark Dickinson18cfada2009-11-23 18:46:41 +0000315- Remove restrictions on precision when formatting floats. E.g.,
316 "%.120g" % 1e-100 used to raise OverflowError, but now gives the
317 requested 120 significant digits instead.

325
Mark Dickinsonb678de82009-11-19 18:41:49 +0000326- Issue #7117: repr(x) for a float x returns a result based on the
327 shortest decimal string that's guaranteed to round back to x under
328 correct rounding (with round-half-to-even rounding mode).
329 Previously it gave a string based on rounding x to 17 decimal digits.
330 repr(x) for a complex number behaves similarly. On platforms where
331 the correctly-rounded strtod and dtoa code is not supported (see below),
332 repr is unchanged.
333
334- Issue #7117: On almost all platforms: float-to-string and
335 string-to-float conversions within Python are now correctly rounded.
336 Places these conversions occur include: str for floats and complex
337 numbers; the float and complex constructors; old-style and new-style
338 numeric formatting; serialization and deserialization of floats and
339 complex numbers using marshal, pickle and json; parsing of float and
340 imaginary literals in Python code; Decimal-to-float conversion.
341
342 The conversions use a Python-adapted version of David Gay's
343 well-known dtoa.c, providing correctly-rounded strtod and dtoa C
344 functions. This code is supported on Windows, and on Unix-like
345 platforms using gcc, icc or suncc as the C compiler. There may be a
346 small number of platforms on which correct operation of this code
347 cannot be guaranteed, so the code is not used: notably, this applies
348 to platforms where the C double format is not IEEE 754 binary64, and
349 to platforms on x86 hardware where the x87 FPU is set to 64-bit
350 precision and Python's configure script is unable to determine how
351 to change the FPU precision. On these platforms conversions use the
352 platform strtod and dtoa, as before.
353
Mark Dickinsonbd15a062009-11-18 19:33:35 +0000354- Issue #7117: Backport round implementation from Python 3.x. round
Mark Dickinsonb678de82009-11-19 18:41:49 +0000355 now uses the correctly-rounded string <-> float conversions
356 described above (when available), and so produces correctly rounded
357 results that will display nicely under the float repr. There are
358 two related small changes: (1) round now accepts any class with an
359 __index__ method for its second argument (but no longer accepts
Mark Dickinsonbd15a062009-11-18 19:33:35 +0000360 floats for the second argument), and (2) an excessively large second
361 integer argument (e.g., round(1.234, 10**100)) no longer raises an
362 exception.

Eric Smitha985a3a2009-05-05 18:26:08 +0000510- Issue #5920: For float.__format__, change the behavior with the

512 to be like 'g' but with at least one decimal point and with a
513 default precision of 12. Previously, the behavior the same but with
514 a default precision of 6. This more closely matches str(), and
515 reduces surprises when adding alignment flags to the empty

Raymond Hettinger08259e82009-02-18 23:10:19 +0000614- Running Python with the -3 option now also warns about classic division
615 for ints and longs.
616
Mark Dickinson2ffb26f2009-02-15 10:13:41 +0000617- Issue #5260: Long integers now consume less memory: average
618 saving is 2 bytes per long on a 32-bit system and 6 bytes per long
619 on a 64-bit system.
620
Antoine Pitrou76a4b892009-02-13 13:52:33 +0000621- Issue #5186: Reduce hash collisions for objects with no __hash__ method by

Mark Dickinsonc97c9092009-02-09 14:18:43 +0000624- Issue #4575: Fix Py_IS_INFINITY macro to work correctly on x87 FPUs:
625 it now forces its argument to double before testing for infinity.
626
Benjamin Petersone18ef192009-01-20 14:21:16 +0000627- Issue #4978: Passing keyword arguments as unicode strings is now allowed.
628
Georg Brandl29c6a282009-04-05 20:23:13 +0000629- Issue #1242657: the __len__() and __length_hint__() calls in several tools
Raymond Hettingerb5163702009-02-02 21:50:13 +0000630 were suppressing all exceptions. These include list(), filter(), map(),
631 zip(), and bytearray().
632
Benjamin Peterson596d3062009-01-19 15:42:23 +0000633- os.ftruncate raises OSErrors instead of IOErrors for consistency with other os
634 functions.
635
Benjamin Peterson5848d1f2009-01-19 00:08:08 +0000636- Issue #4991: Passing invalid file descriptors to io.FileIO now raises an

640
Antoine Pitrouc2f02212009-01-13 23:13:52 +0000641- Issue #4935: The overflow checking code in the expandtabs() method common
642 to str, bytes and bytearray could be optimized away by the compiler, letting
643 the interpreter segfault instead of raising an error.
644
Amaury Forgeot d'Arca40d5732009-01-12 23:36:55 +0000645- Issue #3720: Fix a crash when an iterator modifies its class and removes its

651
Antoine Pitrou4c5ecb72009-01-09 21:40:55 +0000652- Issue #4074: Change the criteria for doing a full garbage collection (i.e.
653 collecting the oldest generation) so that allocating lots of objects without
654 destroying them does not show quadratic performance. Based on a proposal by
Benjamin Petersond50a5d52009-07-13 00:03:20 +0000655 Martin von Löwis at

659
Antoine Pitroue96d4ea2009-01-06 18:10:47 +0000660- Issue #1180193: When importing a module from a .pyc (or .pyo) file with
661 an existing .py counterpart, override the co_filename attributes of all
662 code objects if the original filename is obsolete (which can happen if the
663 file has been renamed, moved, or if it is accessed through different paths).
664 Patch by Ziga Seilnacht and Jean-Paul Calderone.
665
Martin v. Löwis5344c992009-01-02 20:32:55 +0000666- Issue #4075: Use OutputDebugStringW in Py_FatalError.

Hirokazu Yamamoto99a1b202009-01-01 15:45:39 +0000668- Issue #4797: IOError.filename was not set when _fileio.FileIO failed to open
669 file with `str' filename on Windows.
670
Antoine Pitrouaa687902009-01-01 14:11:22 +0000671- Issue #3680: Reference cycles created through a dict, set or deque iterator
672 did not get collected.
673
Nick Coghlan180e4002008-12-30 01:18:48 +0000674- Issue #4701: PyObject_Hash now implicitly calls PyType_Ready on types
675 where the tp_hash and tp_dict slots are both NULL.
676
Benjamin Peterson7af65562008-12-29 17:56:58 +0000677- Issue #4764: With io.open, IOError.filename is set when trying to open a
678 directory on POSIX systems.
679
Benjamin Petersonfe231b02008-12-29 17:47:42 +0000680- Issue #4764: IOError.filename is set when trying to open a directory on POSIX
681 systems.

684 bytearray.translate(). It was always allowed for bytes.translate().
685
Skip Montanarof205c132008-12-23 03:30:15 +0000686- Added test case to ensure attempts to read from a file opened for writing
687 fail.
688
Antoine Pitrou73c0e652008-12-17 22:46:54 +0000689- Issue #2467: gc.DEBUG_STATS reported invalid elapsed times. Also, always

699 context manager returns a value that cannot be converted to a bool.
700
Jeffrey Yasskinffd42cf2008-12-10 07:35:02 +0000701- Issue #4597: Fixed several opcodes that weren't always propagating
702 exceptions.
703
Mark Dickinson826f3fe2008-12-05 21:55:28 +0000704- Issue #4445: Replace "sizeof(PyStringObject)" with
705 "offsetof(PyStringObject, ob_sval) + 1" when allocating memory for
706 str instances. On a typical machine this saves 3 bytes of memory
707 (on average) per string allocation.
708
Amaury Forgeot d'Arcdc619012008-11-22 20:01:18 +0000709- Issue #3996: On Windows, the PyOS_CheckStack function would cause the
710 interpreter to abort ("Fatal Python error: Could not reset the stack!")
711 instead of throwing a MemoryError.
712
Raymond Hettinger7989a4d2008-12-03 15:42:10 +0000713- Issue #3689: The list reversed iterator now supports __length_hint__
714 instead of __len__. Behavior now matches other reversed iterators.
715
Benjamin Petersonc078f922008-11-21 22:27:24 +0000716- Issue #4367: Python would segfault during compiling when the unicodedata
717 module couldn't be imported and \N escapes were present.
718
Vinay Sajip213faca2008-12-03 23:22:58 +0000719- Issue #4233: Changed semantic of ``_fileio.FileIO``'s ``close()``
Amaury Forgeot d'Arc32265652008-11-20 23:34:31 +0000720 method on file objects with closefd=False. The file descriptor is still
721 kept open but the file object behaves like a closed file. The ``FileIO``
722 object also got a new readonly attribute ``closefd``.
723
Benjamin Peterson46cc6d12008-11-19 21:49:09 +0000724- Issue #4348: Some bytearray methods returned that didn't cause any change to
725 the bytearray, returned the same bytearray instead of a copy.
726
Amaury Forgeot d'Arc7cfe7ea2008-11-18 22:19:37 +0000727- Issue #4317: Fixed a crash in the imageop.rgb2rgb8() function.
728

730
Benjamin Peterson6624a9f2008-11-03 15:14:51 +0000731- Issue #4048: The parser module now correctly validates relative imports.
732
Benjamin Petersondcee09d2008-10-31 02:16:05 +0000733- Issue #4225: ``from __future__ import unicode_literals`` didn't work in an
734 exec statement.
735
Amaury Forgeot d'Arc69a9c5b2008-10-30 21:18:34 +0000736- Issue #4176: Fixed a crash when pickling an object which ``__reduce__``
737 method does not return iterators for the 4th and 5th items.
738
Benjamin Petersonbdca9422008-10-26 20:21:13 +0000739- Issue #4209: Enabling unicode_literals and the print_function in the same
740 __future__ import didn't work.
741
Benjamin Peterson399b1fe2008-10-25 02:53:28 +0000742- Using ``nonlocal`` as a variable name will now raise a Py3k SyntaxWarning
Georg Brandl7fb00ad2008-10-25 07:00:52 +0000743 because it is a reserved word in 3.x.
Benjamin Peterson399b1fe2008-10-25 02:53:28 +0000744
Hirokazu Yamamoto10a018c2008-10-09 10:00:30 +0000745- On windows, os.chdir given unicode was not working if GetCurrentDirectoryW
746 returned a path longer than MAX_PATH. (But It's doubtful this code path is
747 really executed because I cannot move to such directory on win2k)
748
Amaury Forgeot d'Arcd78b9dc2008-10-07 20:32:10 +0000749- Issue #4069: When set.remove(element) is used with a set element, the element
750 is temporarily replaced with an equivalent frozenset. But the eventual
751 KeyError would always report the empty frozenset([]) as the missing key. Now
752 it correctly refers to the initial element.
753
Antoine Pitrouae5bece2008-12-06 21:29:24 +0000754- Issue #4509: Various issues surrounding resize of bytearray objects to
755 which there are buffer exports.

765
Matthias Klose91a3b9e2009-04-05 21:19:13 +0000766- Issue #1113244: Py_XINCREF, Py_DECREF, Py_XDECREF: Add `do { ... } while (0)'
767 to avoid compiler warnings.

Gregory P. Smith2b3eb372009-04-05 23:48:26 +0000769- Issue #5705: os.setuid() would not accept values > 2**31-1 but pwd.getpwnam()
770 returned them on 64bit platforms.
771
Walter Dörwalded960ac2009-05-03 22:36:33 +0000772- Issue #5108: Handle %s like %S and %R in PyUnicode_FromFormatV(): Call
773 PyUnicode_DecodeUTF8() once, remember the result and output it in a second
774 step. This avoids problems with counting UTF-8 bytes that ignores the effect
775 of using the replace error handler in PyUnicode_DecodeUTF8().
776
Walter Dörwald726ba8e2009-05-06 14:32:35 +0000777- Issue #3739: The unicode-internal encoder now reports the number of characters
778 consumed like any other encoder (instead of the number of bytes).
779
Benjamin Peterson91c12eb2009-12-03 02:52:39 +0000780- Issue #2422: When compiled with the ``--with-valgrind`` option, the
781 pymalloc allocator will be automatically disabled when running under
782 Valgrind. This gives improved memory leak detection when running
783 under Valgrind, while taking advantage of pymalloc at other times.

R. David Murray820b0ea2009-12-03 23:57:59 +00002005 file in the Lib/test directory, which might be read-only for the

2020 leak-chasing test runs give sensible results. The previous method of

Martin v. Löwis9fa5a282008-09-11 06:53:30 +00002163- Issue #3642: Suppress warning in obmalloc when size_t is larger than uint.
2164
Amaury Forgeot d'Arc05e34492008-09-10 22:04:45 +00002165- Issue #3743: In a few places, PY_FORMAT_SIZE_T was incorrectly used with
2166 PyString_FromFormat or PyErr_Format to display size_t values. The macro
2167 PY_FORMAT_SIZE_T is designed to select the correct format for the OS
2168 ``printf`` function, whereas PyString_FromFormat has an independent
2169 implementation and uses "%zd" on all platforms for size_t values.
2170 This makes a difference on win64, where ``printf`` needs "%Id" to display
2171 64bit values.

Benjamin Peterson97179b02008-09-09 20:55:01 +00002173- Issue #3634: _weakref.ref(Exception).__init__() gave invalid return value on

2177 object; previously an int would be returned for small values. the __long__

Vinay Sajip35e3b032008-09-01 14:33:59 +00002187 PyArg_ParseTuple and friends, which occurred when the argument for "s*"
Antoine Pitroud4ae97b2008-08-29 18:39:48 +00002188 was correctly parsed but parsing of subsequent arguments failed.
2189
Vinay Sajip35e3b032008-09-01 14:33:59 +00002190- Issue #2534: speed up isinstance() and issubclass() by 50-70%, so as to
Antoine Pitrou0668c622008-08-26 22:42:08 +00002191 match Python 2.5 speed despite the __instancecheck__ / __subclasscheck__
2192 mechanism. In the process, fix a bug where isinstance() and issubclass(),
2193 when given a tuple of classes as second argument, were looking up
2194 __instancecheck__ / __subclasscheck__ on the tuple rather than on each
2195 type object.
2196
Neal Norwitz18aa3882008-08-24 05:04:52 +00002197- Fix crashes on memory allocation failure found with failmalloc.

Jesse Noller438195f2009-01-18 21:04:36 +00002290- Issue #4301: Patch the logging module to add processName support, remove
2291 _check_logger_class from multiprocessing.
2292
Amaury Forgeot d'Arc293924b2008-09-02 23:19:56 +00002293- Issue #2975: When compiling several extension modules with Visual Studio 2008
2294 from the same python interpreter, some environment variables would grow
2295 without limit.
2296
Benjamin Peterson37346b22008-08-23 20:27:43 +00002297- Issue #3643: Added a few more checks to _testcapi to prevent segfaults by

2313 wrapper for warnings.catch_warnings() that makes it easier to check
2314 that expected warning messages are being reported.
2315

Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00002334What's New in Python 2.6 beta 3?
2335================================
2336
Barry Warsaw07a4a382008-08-21 01:15:08 +00002337*Release date: 20-Aug-2008*
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00002338
2339Core and Builtins
2340-----------------
2341
Guido van Rossumf8402962008-08-20 15:01:50 +00002342- Issue #1878: Remove Py_TPFLAGS_HAVE_VERSION_TAG from
2343 Py_TPFLAGS_DEFAULT when not building the core. This means 3rd party
2344 extensions do not automatically benefit from the class attribute
2345 cache; they will have to explicitly add Py_TPFLAGS_HAVE_VERSION_TAG
2346 to their tp_flags field if they care. This is a backwards
2347 compatibility feature; in 3.0, all types will use the cache by
2348 default.
2349
Benjamin Petersonf647dc12008-08-20 01:27:30 +00002350- Keyword arguments can now follow starred arguments. (``f(a, *args,
2351 keyword=23)`` is now valid syntax.)
2352
Thomas Heller0ad5ae02008-08-19 19:25:04 +00002353- ctypes function pointers that are COM methods have a boolean True
2354 value again.
2355
Martin v. Löwisf91d46a2008-08-12 14:49:50 +00002356- Issue #3139: Make buffer-interface thread-safe wrt. PyArg_ParseTuple,
2357 by denying s# to parse objects that have a releasebuffer procedure,
2358 and introducing s*.
2359
Georg Brandl1e13ea92008-08-11 09:07:59 +00002360- Issue #3537: Fix an assertion failure when an empty but presized dict
2361 object was stored in the freelist.
2362
Mark Dickinsonb6467572008-08-04 21:30:09 +00002363- Issue #1481296: Make long(float('nan')) and int(float('nan')) raise
2364 ValueError consistently across platforms.
2365
Amaury Forgeot d'Arc39fd6722008-07-31 21:28:03 +00002366- Issue #3479: On platforms where sizeof(int) is smaller than sizeof(long)
2367 (64bit Unix, for example), unichr() would truncate its argument and return
2368 u'\x00' for unichr(2**32). Now it properly raises an OverflowError.
2369
Neal Norwitze7d8be82008-07-31 17:17:14 +00002370- Apply security patches from Apple.
2371
Amaury Forgeot d'Arc246daed2008-07-31 00:42:16 +00002372- Issue #2542: Now that issubclass() may call arbitrary code, ensure that
2373 PyErr_ExceptionMatches returns 0 when an exception occurs there.
2374
Antoine Pitrou92f82162008-07-25 22:22:08 +00002375- Issue #1819: function calls with several named parameters are now on
2376 average 35% faster (as measured by pybench).
2377
Amaury Forgeot d'Arce4921fe2008-07-21 22:00:38 +00002378- Issue #2378: An unexpected UnboundLocalError or NameError could appear when
2379 the python debugger steps into a class statement: the free variables (local
2380 variables defined in an outer scope) would be deleted from the outer scope.
2381
Gregory P. Smith0470bab2008-07-22 04:46:32 +00002382- Issue #2620: Overflow checking when allocating or reallocating memory
2383 was not always being done properly in some python types and extension
2384 modules. PyMem_MALLOC, PyMem_REALLOC, PyMem_NEW and PyMem_RESIZE have
2385 all been updated to perform better checks and places in the code that
2386 would previously leak memory on the error path when such an allocation
2387 failed have been fixed.
2388
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00002389Library
2390-------
2391
Hirokazu Yamamoto838c79f2008-08-20 13:14:07 +00002392- Issue #3612: Added some missing basic types in ctypes.wintypes.
2393
Benjamin Petersone977ad42008-08-20 01:42:01 +00002394- The methods ``is_in_tuple()``, ``is_vararg()``, and ``is_keywordarg()`` of
2395 symtable.Symbol have been deprecated for removal in 3.0 and the next release.
2396
Amaury Forgeot d'Arc351ffb82008-08-18 19:23:47 +00002397- Issue #2234: distutils failed for some versions of the cygwin compiler. The
2398 version reported by these tools does not necessarily follow the python
2399 version numbering scheme, so the module is less strict when parsing it.
2400
Nick Coghlanf70385a2008-08-18 12:42:46 +00002401- Issue #2235: Added Py3k warnings for types which will become unhashable
2402 under the stricter __hash__ inheritance rules in 3.0. Several types
2403 which did not meet the rules for hash invariants and were already
2404 unhashable in 3.0 have now been explicitly flagged as unhashable in
2405 2.6 as well (collections.Mapping, collections.Set, unittest.TestSuite,
2406 xml.dom.minidom.NamedNodeMap, numbers.Number, UserList.UserList)
2407
Brett Cannon88f801d2008-08-18 00:46:22 +00002408- Update __all__ for cookielib, csv, os, urllib2, and weakref to include things
2409 imported into the module but exposed as part of the module's API.
2410

Brett Cannon25c9d6a2008-08-17 22:10:11 +00002415- Remove unneeded imports of 'warnings' from shelve, filecmp, and dummy_thread.
2416
Hirokazu Yamamoto41a81eb2008-08-17 13:10:46 +00002417- Issue #3575: Incremental decoder's decode function now takes bytearray
2418 by using 's*' instead of 't#'.
2419
Mark Dickinson3e4caeb2009-02-21 20:27:01 +00002420- Issue #2222: Fixed reference leak when occurred os.rename()
Hirokazu Yamamoto7f30a682008-08-17 09:46:56 +00002421 fails unicode conversion on 2nd parameter. (windows only)
2422
Facundo Batista94f243a2008-08-17 03:38:39 +00002423- Issue 2464. urllib2 now supports a malformation in the URL received
2424 in a redirect.
2425
Brett Cannonabe423e2008-08-16 21:47:07 +00002426- Silence the DeprecationWarning raised when importing mimetools in
Brett Cannon721b1452008-08-16 22:00:27 +00002427 BaseHTTPServer, cgi (and rfc822), httplib.
Brett Cannonabe423e2008-08-16 21:47:07 +00002428
Facundo Batistaeb90b782008-08-16 14:44:07 +00002429- Issue #2776: fixed small issue when handling an URL with double slash
2430 after a 302 response in the case of not going through a proxy.
2431
Antoine Pitroub90a8be2008-08-15 21:03:21 +00002432- Issue #2676: in the email package, content-type parsing was hanging on
2433 pathological input because of quadratic or exponential behaviour of a
2434 regular expression.
2435
Antoine Pitrou11ec65d2008-08-14 21:04:30 +00002436- Issue #3476: binary buffered reading through the new "io" library is now
2437 thread-safe.
2438
Brett Cannonbf3157b2008-08-14 05:00:03 +00002439- Silence the DeprecationWarning of rfc822 when it is imported by mimetools
2440 since mimetools itself is deprecated. Because modules are cached, all
2441 subsequent imports of rfc822 will not raise a visible DeprecationWarning.
2442
Antoine Pitrou9fcd4b32008-08-11 17:21:36 +00002443- Issue #3134: shutil referenced undefined WindowsError symbol.
2444
Robert Schuppenies14646332008-08-10 11:01:53 +00002445- Issue #1342811: Fix leak in Tkinter.Menu.delete. Commands associated to
2446 menu entries were not deleted.
2447
Brett Cannon83e81842008-08-09 23:30:55 +00002448- Copied the implementation of reduce() to _functools.reduce() to have a
2449 version that did not raise a DeprecationWarning under -3.
2450
Antoine Pitrou76b8bee2008-08-09 17:27:23 +00002451- Issue #3205: When iterating over a BZ2File fails allocating memory, raise
2452 a MemoryError rather than silently stop the iteration.
2453
Guido van Rossum59ce9012008-08-09 14:55:34 +00002454- Issue #3487: sre "bytecode" validator. Passing invalid "re-bytecode"
2455 to _sre.compile() will now be rejected. This should not affect anybody
2456 since the re.compile() function never generates invalid re-bytecode.
2457
Skip Montanaroa032bf42008-08-08 22:52:51 +00002458- Issue #3436: Make csv.DictReader's fieldnames attribute a property so that
2459 upon first access it can be automatically initialized from the csv file if
2460 it wasn't initialized during instantiation.
2461
Brett Cannon3aa2a492008-08-06 22:28:09 +00002462- Issue #2338: Create imp.reload() to help with transitioning to Python 3.0 as
2463 the reload() built-in has been removed.
2464
Brett Cannon7e30b672008-08-04 21:52:25 +00002465- Changed code in the following modules/packages to remove warnings raised
Brett Cannonc1b76e42008-08-09 23:06:16 +00002466 while running under the ``-3`` flag: aifc, asynchat, asyncore, bdb, bsddb,

2474 raised an AttributeError.
2475
Benjamin Peterson01a24322008-07-28 23:35:27 +00002476- Issue #2523: Fix quadratic behaviour when read()ing a binary file without
Antoine Pitroude781a42008-08-09 12:43:23 +00002477 asking for a specific length. This problem only affected files opened
2478 using the new "io" module, not the built-in open() function.
Benjamin Peterson01a24322008-07-28 23:35:27 +00002479
Mark Dickinsonfe84cce2008-07-27 06:39:07 +00002480- Issue #3449: Update decimal module to use most recent specification
2481 (v. 1.68) and tests (v. 2.58) from IBM.

2502
Antoine Pitrou5fdfa3e2008-07-25 19:42:26 +00002503- Issue #3394: zipfile.writestr sets external attributes when passed a
2504 file name rather than a ZipInfo instance, so files are extracted with
2505 mode 0600 rather than 000 under Unix.
2506
Gregory P. Smitha36f8fe2008-08-04 00:13:29 +00002507- Issue #1857: subprocess.Popen.poll gained an additional _deadstate keyword
2508 argument in python 2.5, this broke code that subclassed Popen to include its
2509 own poll method. Fixed my moving _deadstate to an _internal_poll method.

Nick Coghlan6e8fef02008-08-18 13:14:22 +00002519- Issue #2235: the C API function PyObject_HashNotImplemented and its
2520 interaction with the tp_hash slot (added in 2.6b2) are now documented
2521
Nick Coghlan2a0c2b12008-08-04 12:47:17 +00002522- Issue #643841: The language reference now provides more detailed
2523 coverage of the lookup process for special methods. The disclaimers
2524 regarding lack of coverage of new-style classes have also been
2525 removed, since the coverage is now fairly reasonable.

Raymond Hettingere3ae6552008-06-20 04:18:15 +00002528What's New in Python 2.6 beta 2?
2529================================
2530
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00002531*Release date: 17-Jul-2008*
2532
Raymond Hettingere3ae6552008-06-20 04:18:15 +00002533Core and Builtins
2534-----------------
2535
Georg Brandl3e483f62008-07-16 22:57:41 +00002536- Issue #3156: Fix inconsistent behavior of the bytearray type: all
2537 its methods now allow for items objects that can be converted to
2538 an integer using operator.index().
2539
Mark Dickinson64b7e502008-07-16 09:40:03 +00002540- Issue #3360: Fix incorrect parsing of '020000000000.0', which
2541 produced a ValueError instead of giving the correct float.
2542
Eric Smitha5fa5a22008-07-16 00:11:49 +00002543- Issue #3083: Add alternate (#) formatting for bin, oct, hex output
2544 for str.format(). This adds the prefix 0b, 0o, or 0x, respectively.
2545
Mark Dickinson7103aa42008-07-15 19:08:33 +00002546- Issue #3008: the float type has a new instance method 'float.hex'
2547 and a new class method 'float.fromhex' to convert floating-point
2548 numbers to and from hexadecimal strings, respectively.
2549
Nick Coghlan6d6bd442008-07-15 15:40:22 +00002550- Issue #2235: __hash__ is once again inherited by default. To allow
2551 collections.Hashable to remain meaningful in the presence of the
2552 default hash implementation (object.__hash__), it is now possible
2553 to explicit block inheritance of hash by setting __hash__=None at
2554 the Python level, or tp_hash=PyObject_HashNotImplemented at the C
2555 level.
2556
Nick Coghlanb028f502008-07-13 14:52:36 +00002557- Issue #3221: Issue a RuntimeWarning instead of raising SystemError if
2558 the parent module cannot be found while performing an absolute import.
2559 This means that an incorrectly defined __package__ attribute will
2560 now only prevent relative imports in that module rather than causing
2561 all imports from that module to fail.
2562
Nick Coghlan14ff9942008-07-08 14:21:42 +00002563- Issue #2517: Allow unicode messages in Exceptions again by correctly
2564 bypassing the instance dictionary when looking up __unicode__ on
2565 new-style classes.

2579 slice(None, 10, -1).indices(10) returns (9, 9, -1) instead of (9,

Georg Brandl5cc774e2008-06-11 20:28:06 +00003034 PPC64 and x86_64 support in one binary).
Ronald Oussoren5640ce22008-06-05 12:58:24 +00003035

Georg Brandl3ee81df2008-05-17 18:14:43 +00003096- Issue #1631171: Re-implement the 'warnings' module in C (the
3097 original Python code has been kept as backup). This will allow for
3098 using the 'warning's machinery in such places as the parser where
3099 use of pure Python code is not possible. Both the ``showarning()``
3100 and ``formatwarning()`` gain an optional 'line' argument which is
3101 not called by default for backwards-compatibility reasons. Setting
3102 ``warnings.showwarning()`` to an implementation that lacks support
3103 for the ``line`` argument will raise a DeprecationWarning.

Georg Brandl3ee81df2008-05-17 18:14:43 +00003166- Issue #2550: The approach used by client/server code for obtaining
3167 ports to listen on in network-oriented tests has been refined in an
3168 effort to facilitate running multiple instances of the entire
3169 regression test suite in parallel without issue.
3170 test_support.bind_port() has been fixed such that it will always
3171 return a unique port -- which wasn't always the case with the
3172 previous implementation, especially if socket options had been set
3173 that affected address reuse (i.e. SO_REUSEADDR, SO_REUSEPORT). The
3174 new implementation of bind_port() will actually raise an exception
3175 if it is passed an AF_INET/SOCK_STREAM socket with either the
3176 SO_REUSEADDR or SO_REUSEPORT socket option set. Furthermore, if
3177 available, bind_port() will set the SO_EXCLUSIVEADDRUSE option on
3178 the socket it's been passed. This currently only applies to
3179 Windows. This option prevents any other sockets from binding to the
3180 host/port we've bound to, thus removing the possibility of the
3181 'non-deterministic' behaviour, as Microsoft puts it, that occurs
3182 when a second SOCK_STREAM socket binds and accepts to a host/port
3183 that's already been bound by another socket. The optional preferred
3184 port parameter to bind_port() has been removed. Under no
3185 circumstances should tests be hard coding ports!
3186
3187 test_support.find_unused_port() has also been introduced, which will
3188 pass a temporary socket object to bind_port() in order to obtain an
3189 unused port. The temporary socket object is then closed and
3190 deleted, and the port is returned. This method should only be used
3191 for obtaining an unused port in order to pass to an external program
3192 (i.e. the -accept [port] argument to openssl's s_server mode) or as
3193 a parameter to a server-oriented class that doesn't give you direct
3194 access to the underlying socket used.
3195
3196 Finally, test_support.HOST has been introduced, which should be used
3197 for the host argument of any relevant socket calls (i.e. bind and
3198 connect).
Trent Nelsone41b0062008-04-08 23:47:30 +00003199
3200 The following tests were updated to following the new conventions:
Georg Brandl3ee81df2008-05-17 18:14:43 +00003201 test_socket, test_smtplib, test_asyncore, test_ssl, test_httplib,
Trent Nelsone41b0062008-04-08 23:47:30 +00003202 test_poplib, test_ftplib, test_telnetlib, test_socketserver,
3203 test_asynchat and test_socket_ssl.
3204
Georg Brandl3ee81df2008-05-17 18:14:43 +00003205 It is now possible for multiple instances of the regression test
3206 suite to run in parallel without issue.

Georg Brandl3ee81df2008-05-17 18:14:43 +00003390 optional: it defaults to the traceback of the exception that is
3391 currently being handled (is mandatory to be in the middle of an
3392 exception, otherwise it raises ValueError).

3409
Thomas Heller78b8f442008-03-05 14:53:39 +00003410- The bundled libffi copy is now in sync with the recently released
3411 libffi3.0.4 version, apart from some small changes to
Georg Brandl3ee81df2008-05-17 18:14:43 +00003412 Modules/_ctypes/libffi/configure.ac. On OS X, preconfigured libffi
3413 files are used. On all linux systems the --with-system-ffi
3414 configure option defaults to "yes".

3473-----------------
3474
Fred Drakea8ee94b2008-03-01 02:45:07 +00003475- Issue #2051: pyc and pyo files are no longer created with permission
Barry Warsaw52973612008-03-01 02:23:38 +00003476 644. The mode is now inherited from the py file.
Christian Heimes40346852008-02-23 17:52:07 +00003477
Georg Brandlad61bc82008-02-23 15:11:18 +00003478- Issue #2067: file.__exit__() now calls subclasses' close() method.
3479
3480- Patch #1759: Backport of PEP 3129 class decorators.
Christian Heimes5224d282008-02-23 15:01:05 +00003481
Vinay Sajipb7edfc42008-04-02 21:10:23 +00003482- Issue #1881: An internal parser limit has been increased. Also see
Facundo Batistafc2d0102008-02-23 12:01:13 +00003483 issue 215555 for a discussion.
3484
Eric Smitha73fbe72008-02-23 03:09:44 +00003485- Added the future_builtins module, which contains hex() and oct().
3486 These are the PEP 3127 version of these functions, designed to be
3487 compatible with the hex() and oct() builtins from Python 3.0. They
3488 differ slightly in their output formats from the existing, unchanged
3489 Python 2.6 builtins. The expected usage of the future_builtins
3490 module is:
3491 from future_builtins import hex, oct
3492
Eric Smith7ef40bf2008-02-20 23:34:22 +00003493- Issue #1600: Modifed PyOS_ascii_formatd to use at most 2 digit
3494 exponents for exponents with absolute value < 100. Follows C99
3495 standard. This is a change on Windows, which would use 3 digits.
3496 Also, added 'n' to the formats that PyOS_ascii_formatd understands,
3497 so that any alterations it does to the resulting string will be
3498 available in stringlib/formatter.h (for float.__format__).
3499
Eric Smith5a3c1352008-02-19 13:21:56 +00003500- Implemented PEP 3101, Advanced String Formatting. This adds a new
3501 builtin format(); a format() method for str and unicode; a
3502 __format__() method to object, str, unicode, int, long, float, and
3503 datetime; the class string.Formatter; and the C API
3504 PyObject_Format().
3505
Georg Brandl3ee81df2008-05-17 18:14:43 +00003506- Fixed several potential crashes, all caused by specially crafted
3507 __del__ methods exploiting objects in temporarily inconsistent
3508 state.
Amaury Forgeot d'Arc632fad32008-02-16 20:55:24 +00003509
Vinay Sajipb7edfc42008-04-02 21:10:23 +00003510- Issue #2115: Important speedup in setting __slot__ attributes. Also
Georg Brandl3ee81df2008-05-17 18:14:43 +00003511 prevent a possible crash: an Abstract Base Class would try to access
3512 a slot on a registered virtual subclass.
Amaury Forgeot d'Arc60d6c7f2008-02-15 21:22:45 +00003513
Georg Brandl3ee81df2008-05-17 18:14:43 +00003514- Fixed repr() and str() of complex numbers with infinity or nan as
3515 real or imaginary part.
Christian Heimes2f0da532008-02-15 06:57:08 +00003516
Georg Brandl3ee81df2008-05-17 18:14:43 +00003517- Clear all free lists during a gc.collect() of the highest generation
3518 in order to allow pymalloc to free more arenas. Python may give back
3519 memory to the OS earlier.
Christian Heimes3b718a72008-02-14 12:47:33 +00003520
Georg Brandl3ee81df2008-05-17 18:14:43 +00003521- Issue #2045: Fix an infinite recursion triggered when printing a
3522 subclass of collections.defaultdict, if its default_factory is set
3523 to a bound method.
Amaury Forgeot d'Arcb01aa432008-02-08 00:56:02 +00003524
Christian Heimesf75dbef2008-02-08 00:11:31 +00003525- Fixed a minor memory leak in dictobject.c. The content of the free
3526 list was not freed on interpreter shutdown.
3527
Georg Brandl3ee81df2008-05-17 18:14:43 +00003528- Limit free list of method and builtin function objects to 256
3529 entries each.
Christian Heimes6075a822008-02-06 12:44:34 +00003530
Georg Brandl3ee81df2008-05-17 18:14:43 +00003531- Patch #1953: Added ``sys._compact_freelists()`` and the C API
3532 functions ``PyInt_CompactFreeList`` and ``PyFloat_CompactFreeList``
Christian Heimes422051a2008-02-04 18:00:12 +00003533 to compact the internal free lists of pre-allocted ints and floats.
3534
Georg Brandl3ee81df2008-05-17 18:14:43 +00003535- Issue #1983: Fixed return type of fork(), fork1() and forkpty()
3536 calls. Python expected the return type int but the fork familie
3537 returns pi_t.
Christian Heimes951cc0f2008-01-31 23:08:23 +00003538
Georg Brandl3ee81df2008-05-17 18:14:43 +00003539- Issue #1678380: Fix a bug that identifies 0j and -0j when they
3540 appear in the same code unit.
Mark Dickinson105be772008-01-31 22:17:37 +00003541
Georg Brandl3ee81df2008-05-17 18:14:43 +00003542- Issue #2025: Add tuple.count() and tuple.index() methods to comply
3543 with the collections.Sequence API.
Raymond Hettinger5b07ebc2008-02-07 00:54:20 +00003544

Georg Brandl3ee81df2008-05-17 18:14:43 +00003548- Added ``PyType_ClearCache()`` and ``sys._clear_type_cache`` to clear
3549 the internal lookup cache for ref leak tests.
Christian Heimes908caac2008-01-27 23:34:59 +00003550
Georg Brandl3ee81df2008-05-17 18:14:43 +00003551- Patch #1473257: generator objects gain a gi_code attribute. This is
3552 the same object as the func_code attribute of the function that
3553 produced the generator.
Georg Brandl0cdf9a32008-01-26 14:14:20 +00003554
Georg Brandl3ee81df2008-05-17 18:14:43 +00003555- Issue #1920: "while 0" statements were completely removed by the
3556 compiler, even in the presence of an "else" clause, which is
3557 supposed to be run when the condition is false. Now the compiler
3558 correctly emits bytecode for the "else" suite.
Amaury Forgeot d'Arc31eaafe2008-01-24 22:59:25 +00003559
Guido van Rossumeead05f2008-01-24 18:21:02 +00003560- A few crashers fixed: weakref_in_del.py (issue #1377858);
3561 loosing_dict_ref.py (issue #1303614, test67.py);
3562 borrowed_ref_[34].py (not in tracker).
3563
Vinay Sajipd7cf32e2008-01-24 12:43:33 +00003564- Issue #1069410: The "can't load dll" message box on Windows is
Christian Heimesb2302ba2008-01-23 17:15:06 +00003565 suppressed while an extension is loaded by calling SetErrorMode in
3566 dynload_win.c. The error is still reported properly.
3567
Georg Brandl3ee81df2008-05-17 18:14:43 +00003568- Issue #1915: Python compiles with --enable-unicode=no again. However
Christian Heimes082c9b02008-01-23 14:20:50 +00003569 several extension methods and modules do not work without unicode
3570 support.
3571
Georg Brandl26543b12008-01-21 18:36:51 +00003572- Issue #1882: when compiling code from a string, encoding cookies in the
3573 second line of code were not always recognized correctly.
3574
Georg Brandl14404b62008-01-19 19:27:05 +00003575- Issue #1679: "0x" was taken as a valid integer literal.
3576
Georg Brandl6caad7d2008-01-26 14:19:22 +00003577- Issue #1865: ``bytes`` as an alias for ``str`` and b"" as an alias "" were
Christian Heimes288e89a2008-01-18 18:24:07 +00003578 added.
3579
Christian Heimesc94e2b52008-01-14 04:13:37 +00003580- sys.float_info / PyFloat_GetInfo: The floating point information
3581 object was converted from a dict to a specialized structseq object.
3582
Georg Brandl3ee81df2008-05-17 18:14:43 +00003583- Patch #1816: Added sys.flags structseq. It exposes the status of
3584 most command line arguments and PYTHON* environment variables.
Christian Heimesf31b69f2008-01-14 03:42:48 +00003585
Georg Brandl3ee81df2008-05-17 18:14:43 +00003586- Objects/structseq.c: Implemented new structseq representation. The
3587 patch makes structseqs (e.g. the return value of os.stat) more
3588 readable.
Christian Heimes9c201962008-01-14 03:33:52 +00003589
Georg Brandl3ee81df2008-05-17 18:14:43 +00003590- Patch #1700288: added a type attribute cache that caches method

3600 to forbid Python to attempt to write compiled bytecode files.
Georg Brandl2da0fce2008-01-07 17:09:35 +00003601
Georg Brandl3ee81df2008-05-17 18:14:43 +00003602- Improve some exception messages when Windows fails to load an
3603 extension module. Now we get for example '%1 is not a valid Win32
3604 application' instead of 'error code 193'.
Amaury Forgeot d'Arce0b76952008-01-04 02:04:15 +00003605

Christian Heimes0a8143f2007-12-18 23:22:54 +00003611- Issue #1635: Platform independent creation and representation of NaN
Georg Brandl3ee81df2008-05-17 18:14:43 +00003612 and INF. float("nan"), float("inf") and float("-inf") now work on
3613 every platform with IEEE 754 semantics.
Christian Heimes0a8143f2007-12-18 23:22:54 +00003614
Georg Brandl3ee81df2008-05-17 18:14:43 +00003615- Compiler now generates simpler and faster code for dictionary
3616 literals. The oparg for BUILD_MAP now indicates an estimated
3617 dictionary size. There is a new opcode, STORE_MAP, for adding
3618 entries to the dictionary.

Georg Brandl3ee81df2008-05-17 18:14:43 +00003647- Patch #1739468: Directories and zipfiles containing a __main__.py
3648 file can now be directly executed by passing their name to the
3649 interpreter. The directory/zipfile is automatically inserted as the
3650 first entry in sys.path.

Georg Brandl3ee81df2008-05-17 18:14:43 +00003652- Issue #1265: Fix a problem with sys.settrace, if the tracing
3653 function uses a generator expression when at the same time the
3654 executed code is closing a paused generator.

3661
Georg Brandl3ee81df2008-05-17 18:14:43 +00003662- The enumerate() builtin function is no longer bounded to sequences
3663 smaller than LONG_MAX. Formerly, it raised an OverflowError. Now,
3664 automatically shifts from ints to longs.
Raymond Hettinger8f669372007-10-03 21:18:11 +00003665
Georg Brandl3ee81df2008-05-17 18:14:43 +00003666- Issue #1686386: Tuple's tp_repr did not take into account the
3667 possibility of having a self-referential tuple, which is possible
3668 from C code. Nor did object's tp_str consider that a type's tp_str
3669 could do something that could lead to an inifinite recursion.
3670 Py_ReprEnter() and Py_EnterRecursiveCall(), respectively, fixed the
3671 issues.
Brett Cannon0b14f242007-09-30 19:45:10 +00003672
Georg Brandl3ee81df2008-05-17 18:14:43 +00003673- Issue #1164: It was possible to trigger deadlock when using the
3674 'print' statement to write to a file since the GIL was not released
3675 as needed. Now PyObject_Print() does the right thing along with
3676 various tp_print implementations of the built-in types and those in
3677 the collections module.

Georg Brandl3ee81df2008-05-17 18:14:43 +00003679- Issue #1147: Exceptions were directly allowing string exceptions in
3680 their throw() method even though string exceptions no longer
3681 allowed.

Brett Cannona0c05512007-09-10 21:38:27 +00003685
Brett Cannon1e534b52007-09-07 04:18:30 +00003686- Issue #1202533: Fix infinite recursion calls triggered by calls to
Georg Brandl3ee81df2008-05-17 18:14:43 +00003687 PyObject_Call() never calling back out to Python code to trigger
3688 recursion depth updates/checks. Required the creation of a static
3689 RuntimeError instance in case normalizing an exception put the
3690 recursion check value past its limit. Fixes crashers
3691 infinite_rec_(1|2|4|5).py.

Neal Norwitz0ac60192007-05-27 04:08:54 +00003706- Add new attribute names for function objects. All the func_* become
Georg Brandl3ee81df2008-05-17 18:14:43 +00003707 __*__ attributes. (Some already existed, e.g., __doc__ and
3708 __name__.)
Neal Norwitz0ac60192007-05-27 04:08:54 +00003709
Neal Norwitz8b2bfbc2007-05-23 06:35:32 +00003710- Add -3 option to the interpreter to warn about features that are
3711 deprecated and will be changed/removed in Python 3.0.
3712
Georg Brandl2134e752007-05-21 20:34:16 +00003713- Patch #1686487: you can now pass any mapping after '**' in function
3714 calls.
3715
Collin Winter62903052007-05-18 23:11:24 +00003716- except clauses may now be spelled either "except E, target:" or
Georg Brandl3ee81df2008-05-17 18:14:43 +00003717 "except E as target:". This is to provide forwards compatibility
3718 with Python 3.0.

3724
Vinay Sajip8549ce32007-05-06 17:53:37 +00003725- When __slots__ are set to a unicode string, make it work the same as
Neal Norwitzcbd9ee62007-04-14 05:25:50 +00003726 setting a plain string, ie don't expand to single letter identifiers.
3727
Raymond Hettinger13936692007-04-11 18:40:58 +00003728- Request #1191699: Slices can now be pickled.
3729
Raymond Hettinger4db5fe92007-04-12 04:10:00 +00003730- Request #1193128: str.translate() now allows a None argument for
3731 translations that only remove characters without re-mapping the
3732 remaining characters.
3733
Georg Brandl5cb76c12007-03-21 09:00:39 +00003734- Patch #1682205: a TypeError while unpacking an iterable is no longer

3736
Neal Norwitzaa754b72007-03-21 06:39:48 +00003737- Remove unused file Python/fmod.c.
3738
Guido van Rossum143b5642007-03-23 04:58:42 +00003739- Bug #1683368: The object.__init__() and object.__new__() methods are
3740 now stricter in rejecting excess arguments. The only time when
3741 either allows excess arguments is when it is not overridden and the
3742 other one is. For backwards compatibility, when both are
3743 overridden, it is a deprecation warning (for now; maybe a Py3k
Guido van Rossum234b1ff2007-03-23 19:39:01 +00003744 warning later). Also, type.__init__() insists on the same signature
3745 as supported by type.__new__().
Guido van Rossum143b5642007-03-23 04:58:42 +00003746
Georg Brandl3ee81df2008-05-17 18:14:43 +00003747- Patch #1675423: PyComplex_AsCComplex() now tries to convert an
3748 object to complex using its __complex__() method before falling back
3749 to the __float__() method. Therefore, the functions in the cmath
3750 module now can operate on objects that define a __complex__()
3751 method.
Georg Brandl2b869942007-03-17 16:08:45 +00003752
Georg Brandl3ee81df2008-05-17 18:14:43 +00003753- Patch #1623563: allow __class__ assignment for classes with
3754 __slots__. The old and the new class are still required to have the
3755 same slot names.
Žiga Seilnacht6f2d09c2007-03-16 11:59:38 +00003756

3761 ``object.__reduce_ex__()`` is called with an object that is faking
3762 its type.
Žiga Seilnacht20f43d32007-03-15 11:44:55 +00003763
Georg Brandl3ee81df2008-05-17 18:14:43 +00003764- Patch #1680015: Don't modify __slots__ tuple if it contains an

3768
Georg Brandl7b9c5552007-03-12 14:30:05 +00003769- Bug #1678647: write a newline after printing an exception in any
3770 case, even when converting the value to a string failed.
3771
Georg Brandl871f1bc2007-03-12 13:17:36 +00003772- The dir() function has been extended to call the __dir__() method on
Georg Brandl3ee81df2008-05-17 18:14:43 +00003773 its argument, if it exists. If not, it will work like before. This
3774 allows customizing the output of dir() in the presence of a
3775 __getattr__().
Georg Brandl871f1bc2007-03-12 13:17:36 +00003776
Collin Winter276887b2007-03-12 16:11:39 +00003777- Patch #922167: Python no longer segfaults when faced with infinitely
3778 self-recursive reload() calls (as reported by bug #742342).
3779
Georg Brandl3ee81df2008-05-17 18:14:43 +00003780- Patch #1675981: remove unreachable code from ``type.__new__()``
3781 method.

Georg Brandl3ee81df2008-05-17 18:14:43 +00003783- Patch #1491866: change the complex() constructor to allow
3784 parthensized forms. This means complex(repr(x)) now works instead of
3785 raising a ValueError.
Collin Wintere38051d2007-03-09 20:33:07 +00003786
Georg Brandlaa2321b2007-03-07 00:40:28 +00003787- Patch #703779: unset __file__ in __main__ after running a file. This
Georg Brandl3ee81df2008-05-17 18:14:43 +00003788 makes the filenames the warning module prints much more sensible
3789 when a PYTHONSTARTUP file is used.
Georg Brandlaa2321b2007-03-07 00:40:28 +00003790

3792 exception if the -i command line option or PYTHONINSPECT environment
Georg Brandl3ee81df2008-05-17 18:14:43 +00003793 variable is given, but break into the interactive interpreter just
3794 like on other exceptions or normal program exit.

Georg Brandl098cd692007-03-06 12:17:50 +00003801
Georg Brandl0fca97a2007-03-05 22:28:08 +00003802- Patch #1674228: when assigning a slice (old-style), check for the
3803 sq_ass_slice instead of the sq_slice slot.
3804
Georg Brandl3ee81df2008-05-17 18:14:43 +00003805- When printing an unraisable error, don't print exceptions. before
3806 the name. This duplicates the behavior whening normally printing
3807 exceptions.
Neal Norwitz88516a62007-02-26 22:41:45 +00003808
Georg Brandl3ee81df2008-05-17 18:14:43 +00003809- Bug #1653736: Properly discard third argument to

3864
Armin Rigo7ccbca92006-10-04 12:17:45 +00003865- A number of places, including integer negation and absolute value,

4373
Georg Brandl92a6bae2007-03-13 17:43:32 +00004374- Patch #1603688: ConfigParser.SafeConfigParser now checks values that
Georg Brandl3ee81df2008-05-17 18:14:43 +00004375 are set for invalid interpolation sequences that would lead to

4432 TestCase and TestSuite subclasses (not instances) are no longer
4433 accepted in TestSuite.addTest(). This should cause no
4434 incompatibility since it never made sense with ordinary subclasses
4435 -- the failure just occurred later, with a more cumbersome
4436 exception.

Georg Brandl3ee81df2008-05-17 18:14:43 +00004717- Issue #829951: In the smtplib module, SMTP.starttls() now complies
4718 with RFC 3207 and forgets any knowledge obtained from the server not
4719 obtained from the TLS negotiation itself. Patch contributed by Bill
4720 Fenner.
Gregory P. Smith2b3ba582008-01-17 08:03:17 +00004721
Georg Brandl3ee81df2008-05-17 18:14:43 +00004722- Issue #1339: The smtplib.SMTP class has been refactored a bit such
Gregory P. Smithbde4ae42008-01-17 08:35:49 +00004723 that the SMTP.starttls() caller no longer needs to call ehlo()
4724 beforehand. SMTP.starttls() now raises an exception of the server
Georg Brandl3ee81df2008-05-17 18:14:43 +00004725 does not claim to support starttls. Adds the
4726 SMTP.ehlo_or_helo_if_needed() method. Patch contributed by Bill

4807 complex, tuple, list, dict, set, and frozenset. Formerly, it would
4808 silently miscode subclasses of those types. Now, it raises a

Raymond Hettinger12e94202007-11-07 01:13:09 +00004810

Georg Brandl3ee81df2008-05-17 18:14:43 +00004825 time so that opening a database previously created with the DB_DUP
4826 or DB_DUPSORT flag set will keep the proper behavior on subsequent
4827 opens. Specifically: dictionary assignment to a DB object will
4828 replace all values for a given key when the database allows
4829 duplicate values. DB users should use DB.put(k, v) when they want
4830 to store duplicates; not DB[k] = v.
Gregory P. Smithec10a4a2007-11-05 02:32:26 +00004831

4837 characters with ASCII value less than 32. Also, it correctly quotes
4838 dots only if they occur on a single line, as opposed to the previous
4839 behavior of quoting dots if they are the second character of any
4840 line.
Georg Brandl4aef7272007-03-13 22:49:43 +00004841

5105 without this option!
5106
Martin v. Löwis63bf1492007-11-12 05:14:05 +00005107- Patch #1418: Make the AC_REPLACE_FUNCS object files actually work.
5108
Raymond Hettingerdc1d1ba2007-11-07 02:45:46 +00005109- Add a FAST_LOOPS build option that speeds-up looping by trading away
Georg Brandl3ee81df2008-05-17 18:14:43 +00005110 periodic threadstate and signal checking in tight loops. By
5111 default, this option is turned-off. It should only be enabled in
5112 debugged, performance critical applications.
Raymond Hettingerdc1d1ba2007-11-07 02:45:46 +00005113

5128 returned by python-config if Python was built with --enable-shared
5129 because that prevented the shared library from being used.
5130

5163-----
5164
Georg Brandl3ee81df2008-05-17 18:14:43 +00005165- Unified naming convention for free lists and their limits. All free
5166 lists in Object/ are named ``free_list``, the counter ``numfree``
5167 and the upper limit is a macro ``PyName_MAXFREELIST`` inside an
5168 #ifndef block.
Christian Heimes5b970ad2008-02-06 13:33:44 +00005169
Georg Brandl3ee81df2008-05-17 18:14:43 +00005170- ``PySet_Add()`` can now modify a newly created frozenset. Similarly
5171 to ``PyTuple_SetItem``, it can be used to populate a brand new
5172 frozenset; but it does not steal a reference to the added item.
Amaury Forgeot d'Arccab3d982008-02-03 22:51:43 +00005173
Vinay Sajipb7edfc42008-04-02 21:10:23 +00005174- Added ``PySet_Check()`` and ``PyFrozenSet_Check()`` to the set API.

5180- Patch #1720595: add T_BOOL to the range of structmember types.
5181
5182- Issue #1534: Added ``PyFloat_GetMax()``, ``PyFloat_GetMin()`` and
5183 ``PyFloat_GetInfo()`` to the float API.
5184
Georg Brandl3ee81df2008-05-17 18:14:43 +00005185- Issue #1521: On 64bit platforms, using PyArgs_ParseTuple with the t#
5186 of w# format code incorrectly truncated the length to an int, even
5187 when PY_SSIZE_T_CLEAN is set. The str.decode method used to return
5188 incorrect results with huge strings.
Georg Brandl6caad7d2008-01-26 14:19:22 +00005189
Georg Brandl3ee81df2008-05-17 18:14:43 +00005190- Issue #1629: Renamed Py_Size, Py_Type and Py_Refcnt to Py_SIZE,

5208- Fix some leftovers from the conversion from int to Py_ssize_t
5209 (relevant to strings and sequences of more than 2**31 items).
5210
5211- Make _PyGILState_NoteThreadState() static, it was not used anywhere
5212 outside of pystate.c and should not be necessary.
5213
Georg Brandl3ee81df2008-05-17 18:14:43 +00005214- ``PyImport_Import`` and ``PyImport_ImportModule`` now always do
5215 absolute imports. In earlier versions they might have used relative
5216 imports under some conditions.
Christian Heimes000a0742008-01-03 22:16:32 +00005217
Georg Brandl3ee81df2008-05-17 18:14:43 +00005218- Added case insensitive comparison methods ``PyOS_stricmp(char*,
5219 char*)`` and ``PyOS_strnicmp(char*, char*, Py_ssize_t)``.
Christian Heimes000a0742008-01-03 22:16:32 +00005220
Georg Brandl3ee81df2008-05-17 18:14:43 +00005221- Bug #1542693: remove semi-colon at end of PyImport_ImportModuleEx

Georg Brandl3ee81df2008-05-17 18:14:43 +00005228- Patch #1706: Drop support for Win9x, WinME and NT4. Python now
5229 requires Windows 2000 or greater. The _WINVER and NTDDI_VERSION
5230 macros are set to Win2k for x86/32bit builds and WinXP for AMD64
5231 builds.
Christian Heimes95d64472008-02-09 19:55:22 +00005232

Georg Brandl3ee81df2008-05-17 18:14:43 +00005246- Removed the macfs module. It had been deprecated since Python 2.5.
5247 This lead to the deprecation of macostools.touched() as it relied
5248 solely on macfs and was a no-op under OS X.
