Antoine Pitroue80a6a42010-01-17 12:26:20 +000015- Issue #7561: Operations on empty bytearrays (such as `int(bytearray())`)
16 could crash in many places because of the PyByteArray_AS_STRING() macro
17 returning NULL. The macro now returns a statically allocated empty
18 string instead.
19
Antoine Pitrou64672132010-01-13 07:55:48 +000020- Issue #7622: Improve the split(), rsplit(), splitlines() and replace()
21 methods of bytes, bytearray and unicode objects by using a common
22 implementation based on stringlib's fast search. Patch by Florent Xicluna.
23
Mark Dickinson476279f2010-01-16 10:44:00 +000024- Issue #7632: Fix various str -> float conversion bugs present in 2.7
25 alpha 2, including: (1) a serious 'wrong output' bug that could
26 occur for long (> 40 digit) input strings, (2) a crash in dtoa.c
27 that occurred in debug builds when parsing certain long numeric
Mark Dickinson23df3d22010-01-17 13:37:57 +000028 strings corresponding to subnormal values, (3) a memory leak for
29 some values large enough to cause overflow, and (4) a number of
30 flaws that could lead to incorrectly rounded results.

Benjamin Petersonecdae192010-01-04 00:43:01 +000089- The __complex__ method is now looked up on the class of instances to make it
90 consistent with other special methods.
91
Antoine Pitrou5b7139a2010-01-02 21:12:58 +000092- Issue #7462: Implement the stringlib fast search algorithm for the `rfind`,
93 `rindex`, `rsplit` and `rpartition` methods. Patch by Florent Xicluna.
94
Mark Dickinson1b34d252010-01-01 17:27:30 +000095- Issue #5080: A number of functions and methods previously produced a
96 DeprecationWarning when passed a float argument where an integer was
97 expected. These functions and methods now raise TypeError instead.
98 The majority of the effects of this change are in the extension
99 modules, but some core functions and methods are affected: notably
100 the 'chr', 'range' and 'xrange' builtins, and many unicode/str
101 methods.
102
Benjamin Peterson0f02d392009-12-30 19:34:10 +0000103- Issue #7604: Deleting an unset slotted attribute did not raise an
104 AttributeError.

Mark Dickinson99d652e2009-12-30 12:12:23 +0000106- Issue #7534: Fix handling of IEEE specials (infinities, nans,
107 negative zero) in ** operator. The behaviour now conforms to that
108 described in C99 Annex F.
109
Amaury Forgeot d'Arcc8a2ce72009-12-29 23:06:17 +0000110- Issue #7579: the msvcrt module now has docstrings for all its functions.
111
Amaury Forgeot d'Arc8645a5c2009-12-29 22:03:38 +0000112- Issue #7413: Passing '\0' as the separator to datetime.datetime.isoformat()
113 used to drop the time part of the result.
114
Mark Dickinson46572832009-12-27 14:55:57 +0000115- Issue #1811: improve accuracy and cross-platform consistency for
116 true division of integers: the result of a/b is now correctly
117 rounded for ints a and b (at least on IEEE 754 platforms), and in
118 particular does not depend on the internal representation of a long.
119
Ezio Melottif84caf42009-12-24 22:25:17 +0000120- Issue #6108: unicode(exception) and str(exception) should return the same
121 message when only __str__ (and not __unicode__) is overridden in the subclass.
122
Ronald Oussoren92919a62009-12-24 13:30:58 +0000123- Issue #6834: replace the implementation for the 'python' and 'pythonw'
124 executables on OSX.
125
126 These executables now work properly with the arch(1) command:
127 ``arch -ppc python`` will start a universal binary version of python
128 in PPC mode (unlike previous releases).
129
R. David Murray0a0a1a82009-12-14 16:28:26 +0000130- Issue #1680159: unicode coercion during an 'in' operation no longer masks
131 the underlying error when the coercion fails for the left hand operand.
132
Benjamin Peterson4895af42009-12-13 16:36:53 +0000133- Issue #7491: Metaclass's __cmp__ method was ignored.

144 by Arfrever.
145
Antoine Pitrou80157252010-01-08 19:20:17 +0000146- Issue #7092: Remove py3k warning when importing cPickle. 2to3 handles
147 renaming of `cPickle` to `pickle`. The warning was annoying since there's
148 no alternative to cPickle if you care about performance. Patch by Florent
149 Xicluna.
150

159 speedups by wrapping it in an `io.BufferedReader`. Patch by Nir Aides.
160
161- Issue #3972: httplib.HTTPConnection now accepts an optional source_address

181
Benjamin Petersonddd392c2009-12-13 19:19:07 +0000182- Issue #7349: Make methods of file objects in the io module accept None as an
183 argument where file-like objects (ie StringIO and BytesIO) accept them to mean
184 the same as passing no argument.
185
Benjamin Petersonc4771d22009-12-13 17:31:31 +0000186- Issue #7348: StringIO.StringIO.readline(-1) now acts as if it got no argument

Amaury Forgeot d'Arcd7288712009-12-01 21:51:04 +0000257- Issue #7419: setlocale() could crash the interpreter on Windows when called
258 with invalid values.
259
Eric Smithc4ab8332009-11-29 17:40:57 +0000260- Issue #3382: 'F' formatting for float and complex now convert the
261 result to upper case. This only affects 'inf' and 'nan', since 'f'
262 no longer converts to 'g' for large values.
Amaury Forgeot d'Arcd7288712009-12-01 21:51:04 +0000263
Mark Dickinson9dd5e162009-11-23 20:54:09 +0000264- Remove switch from "%f" formatting to "%g" formatting for floats
265 larger than 1e50 in absolute value.
266
Mark Dickinson18cfada2009-11-23 18:46:41 +0000267- Remove restrictions on precision when formatting floats. E.g.,
268 "%.120g" % 1e-100 used to raise OverflowError, but now gives the
269 requested 120 significant digits instead.
270
Benjamin Peterson89b1a5c2009-11-19 22:58:01 +0000271- Add Py3k warnings for parameter names in parenthesis.

Ronald Oussoren315cd0c2009-11-19 16:25:21 +0000275- Issue #7085: Fix crash when importing some extensions in a thread
276 on MacOSX 10.6.
277
Mark Dickinsonb678de82009-11-19 18:41:49 +0000278- Issue #7117: repr(x) for a float x returns a result based on the
279 shortest decimal string that's guaranteed to round back to x under
280 correct rounding (with round-half-to-even rounding mode).
281 Previously it gave a string based on rounding x to 17 decimal digits.
282 repr(x) for a complex number behaves similarly. On platforms where
283 the correctly-rounded strtod and dtoa code is not supported (see below),
284 repr is unchanged.
285
286- Issue #7117: On almost all platforms: float-to-string and
287 string-to-float conversions within Python are now correctly rounded.
288 Places these conversions occur include: str for floats and complex
289 numbers; the float and complex constructors; old-style and new-style
290 numeric formatting; serialization and deserialization of floats and
291 complex numbers using marshal, pickle and json; parsing of float and
292 imaginary literals in Python code; Decimal-to-float conversion.
293
294 The conversions use a Python-adapted version of David Gay's
295 well-known dtoa.c, providing correctly-rounded strtod and dtoa C
296 functions. This code is supported on Windows, and on Unix-like
297 platforms using gcc, icc or suncc as the C compiler. There may be a
298 small number of platforms on which correct operation of this code
299 cannot be guaranteed, so the code is not used: notably, this applies
300 to platforms where the C double format is not IEEE 754 binary64, and
301 to platforms on x86 hardware where the x87 FPU is set to 64-bit
302 precision and Python's configure script is unable to determine how
303 to change the FPU precision. On these platforms conversions use the
304 platform strtod and dtoa, as before.
305
Mark Dickinsonbd15a062009-11-18 19:33:35 +0000306- Issue #7117: Backport round implementation from Python 3.x. round
Mark Dickinsonb678de82009-11-19 18:41:49 +0000307 now uses the correctly-rounded string <-> float conversions
308 described above (when available), and so produces correctly rounded
309 results that will display nicely under the float repr. There are
310 two related small changes: (1) round now accepts any class with an
311 __index__ method for its second argument (but no longer accepts
Mark Dickinsonbd15a062009-11-18 19:33:35 +0000312 floats for the second argument), and (2) an excessively large second
313 integer argument (e.g., round(1.234, 10**100)) no longer raises an
314 exception.

Eric Smitha985a3a2009-05-05 18:26:08 +0000462- Issue #5920: For float.__format__, change the behavior with the
463 empty presentation type (that is, not one of 'e', 'f', 'g', or 'n')
464 to be like 'g' but with at least one decimal point and with a
465 default precision of 12. Previously, the behavior the same but with
466 a default precision of 6. This more closely matches str(), and
467 reduces surprises when adding alignment flags to the empty
468 presentation type. This also affects the new complex.__format__ in
469 the same way.

605 collecting the oldest generation) so that allocating lots of objects without
606 destroying them does not show quadratic performance. Based on a proposal by
Benjamin Petersond50a5d52009-07-13 00:03:20 +0000607 Martin von Löwis at
Antoine Pitrou4c5ecb72009-01-09 21:40:55 +0000608 http://mail.python.org/pipermail/python-dev/2008-June/080579.html.

611
Antoine Pitroue96d4ea2009-01-06 18:10:47 +0000612- Issue #1180193: When importing a module from a .pyc (or .pyo) file with
613 an existing .py counterpart, override the co_filename attributes of all
614 code objects if the original filename is obsolete (which can happen if the
615 file has been renamed, moved, or if it is accessed through different paths).
616 Patch by Ziga Seilnacht and Jean-Paul Calderone.
617
Martin v. Löwis5344c992009-01-02 20:32:55 +0000618- Issue #4075: Use OutputDebugStringW in Py_FatalError.
619
Hirokazu Yamamoto99a1b202009-01-01 15:45:39 +0000620- Issue #4797: IOError.filename was not set when _fileio.FileIO failed to open
621 file with `str' filename on Windows.
622
Antoine Pitrouaa687902009-01-01 14:11:22 +0000623- Issue #3680: Reference cycles created through a dict, set or deque iterator
624 did not get collected.
625
Nick Coghlan180e4002008-12-30 01:18:48 +0000626- Issue #4701: PyObject_Hash now implicitly calls PyType_Ready on types
627 where the tp_hash and tp_dict slots are both NULL.
628
Benjamin Peterson7af65562008-12-29 17:56:58 +0000629- Issue #4764: With io.open, IOError.filename is set when trying to open a
630 directory on POSIX systems.
631
Benjamin Petersonfe231b02008-12-29 17:47:42 +0000632- Issue #4764: IOError.filename is set when trying to open a directory on POSIX
633 systems.
634
Georg Brandl6425a2f2008-12-28 11:54:53 +0000635- Issue #4759: None is now allowed as the first argument of
636 bytearray.translate(). It was always allowed for bytes.translate().
637
Skip Montanarof205c132008-12-23 03:30:15 +0000638- Added test case to ensure attempts to read from a file opened for writing
639 fail.
640
Antoine Pitrou73c0e652008-12-17 22:46:54 +0000641- Issue #2467: gc.DEBUG_STATS reported invalid elapsed times. Also, always

Amaury Forgeot d'Arcad9b5992008-12-10 23:22:49 +0000650- Issue #4597: Fixed exception handling when the __exit__ function of a
651 context manager returns a value that cannot be converted to a bool.
652
Jeffrey Yasskinffd42cf2008-12-10 07:35:02 +0000653- Issue #4597: Fixed several opcodes that weren't always propagating
654 exceptions.
655
Mark Dickinson826f3fe2008-12-05 21:55:28 +0000656- Issue #4445: Replace "sizeof(PyStringObject)" with
657 "offsetof(PyStringObject, ob_sval) + 1" when allocating memory for
658 str instances. On a typical machine this saves 3 bytes of memory
659 (on average) per string allocation.
660
Amaury Forgeot d'Arcdc619012008-11-22 20:01:18 +0000661- Issue #3996: On Windows, the PyOS_CheckStack function would cause the
662 interpreter to abort ("Fatal Python error: Could not reset the stack!")
663 instead of throwing a MemoryError.
664
Raymond Hettinger7989a4d2008-12-03 15:42:10 +0000665- Issue #3689: The list reversed iterator now supports __length_hint__
666 instead of __len__. Behavior now matches other reversed iterators.
667
Benjamin Petersonc078f922008-11-21 22:27:24 +0000668- Issue #4367: Python would segfault during compiling when the unicodedata
669 module couldn't be imported and \N escapes were present.
670
Vinay Sajip213faca2008-12-03 23:22:58 +0000671- Issue #4233: Changed semantic of ``_fileio.FileIO``'s ``close()``
Amaury Forgeot d'Arc32265652008-11-20 23:34:31 +0000672 method on file objects with closefd=False. The file descriptor is still
673 kept open but the file object behaves like a closed file. The ``FileIO``
674 object also got a new readonly attribute ``closefd``.
675
Benjamin Peterson46cc6d12008-11-19 21:49:09 +0000676- Issue #4348: Some bytearray methods returned that didn't cause any change to
677 the bytearray, returned the same bytearray instead of a copy.
678
Amaury Forgeot d'Arc7cfe7ea2008-11-18 22:19:37 +0000679- Issue #4317: Fixed a crash in the imageop.rgb2rgb8() function.
680
Benjamin Peterson273c2332008-11-17 22:39:09 +0000681- Issue #4230: If ``__getattr__`` is a descriptor, it now functions correctly.
682
Benjamin Peterson6624a9f2008-11-03 15:14:51 +0000683- Issue #4048: The parser module now correctly validates relative imports.
684
Benjamin Petersondcee09d2008-10-31 02:16:05 +0000685- Issue #4225: ``from __future__ import unicode_literals`` didn't work in an
686 exec statement.
687
Amaury Forgeot d'Arc69a9c5b2008-10-30 21:18:34 +0000688- Issue #4176: Fixed a crash when pickling an object which ``__reduce__``
689 method does not return iterators for the 4th and 5th items.
690
Benjamin Petersonbdca9422008-10-26 20:21:13 +0000691- Issue #4209: Enabling unicode_literals and the print_function in the same
692 __future__ import didn't work.
693
Benjamin Peterson399b1fe2008-10-25 02:53:28 +0000694- Using ``nonlocal`` as a variable name will now raise a Py3k SyntaxWarning
Georg Brandl7fb00ad2008-10-25 07:00:52 +0000695 because it is a reserved word in 3.x.
Benjamin Peterson399b1fe2008-10-25 02:53:28 +0000696
Hirokazu Yamamoto10a018c2008-10-09 10:00:30 +0000697- On windows, os.chdir given unicode was not working if GetCurrentDirectoryW
698 returned a path longer than MAX_PATH. (But It's doubtful this code path is
699 really executed because I cannot move to such directory on win2k)
700
Amaury Forgeot d'Arcd78b9dc2008-10-07 20:32:10 +0000701- Issue #4069: When set.remove(element) is used with a set element, the element
702 is temporarily replaced with an equivalent frozenset. But the eventual
703 KeyError would always report the empty frozenset([]) as the missing key. Now
704 it correctly refers to the initial element.
705
Antoine Pitrouae5bece2008-12-06 21:29:24 +0000706- Issue #4509: Various issues surrounding resize of bytearray objects to
707 which there are buffer exports.
708
Benjamin Peterson8d5934b2008-12-27 18:24:11 +0000709- Issue #4748: Lambda generators no longer return a value.

717
Matthias Klose91a3b9e2009-04-05 21:19:13 +0000718- Issue #1113244: Py_XINCREF, Py_DECREF, Py_XDECREF: Add `do { ... } while (0)'
719 to avoid compiler warnings.

Gregory P. Smith2b3eb372009-04-05 23:48:26 +0000721- Issue #5705: os.setuid() would not accept values > 2**31-1 but pwd.getpwnam()
722 returned them on 64bit platforms.
723
Walter Dörwalded960ac2009-05-03 22:36:33 +0000724- Issue #5108: Handle %s like %S and %R in PyUnicode_FromFormatV(): Call
725 PyUnicode_DecodeUTF8() once, remember the result and output it in a second
726 step. This avoids problems with counting UTF-8 bytes that ignores the effect
727 of using the replace error handler in PyUnicode_DecodeUTF8().
728
Walter Dörwald726ba8e2009-05-06 14:32:35 +0000729- Issue #3739: The unicode-internal encoder now reports the number of characters
730 consumed like any other encoder (instead of the number of bytes).
731
Benjamin Peterson91c12eb2009-12-03 02:52:39 +0000732- Issue #2422: When compiled with the ``--with-valgrind`` option, the
733 pymalloc allocator will be automatically disabled when running under
734 Valgrind. This gives improved memory leak detection when running
735 under Valgrind, while taking advantage of pymalloc at other times.

803
Nick Coghlan49868cb2009-11-15 07:30:34 +0000804- Issue #6816: runpy now provides a run_path function that allows Python code
805 to execute file paths that refer to source or compiled Python files as well
806 as zipfiles, directories and other valid sys.path entries that contain a

1972 leak-chasing test runs give sensible results. The previous method of
1973 reaping threads could return successfully while some Thread objects were
1974 still referenced. This also introduces a new private function:

1982
R. David Murray14dcd432009-10-14 13:58:07 +00001983- Issue #7058: Added save/restore for things like sys.argv and cwd to
1984 runtest_inner in regrtest, with warnings if the called test modifies them,
1985 and a new section in the summary report at the end.

Guilherme Polo7f146ab2009-06-21 17:22:50 +00001992- Issue #5450: Moved tests involving loading tk from Lib/test/test_tcl to
1993 Lib/lib-tk/test/test_tkinter/test_loadtk. With this, these tests demonstrate
1994 the same behaviour as test_ttkguionly (and now also test_tk) which is to
1995 skip the tests if DISPLAY is defined but can't be used.
1996
Antoine Pitrou4698d992009-05-31 14:20:14 +00001997- Issue #6152: New option '-j'/'--multiprocess' for regrtest allows running

2001 it easy to import both normal and optimised versions of modules.
2002 test_heapq and test_warnings have been adjusted to use it, tests for
2003 other modules with both C and Python implementations in the stdlib
2004 can be adjusted to use it over time.

R. David Murray41448c52009-03-31 19:57:24 +00002012- regrtest no longer treats ImportError as equivalent to SkipTest. Imports
Vinay Sajip22aa4bb2009-04-16 19:15:49 +00002013 that should cause a test to be skipped are now done using import_module
R. David Murray41448c52009-03-31 19:57:24 +00002014 from test support, which does the conversion.

Martin v. Löwis9fa5a282008-09-11 06:53:30 +00002115- Issue #3642: Suppress warning in obmalloc when size_t is larger than uint.
2116
Amaury Forgeot d'Arc05e34492008-09-10 22:04:45 +00002117- Issue #3743: In a few places, PY_FORMAT_SIZE_T was incorrectly used with
2118 PyString_FromFormat or PyErr_Format to display size_t values. The macro
2119 PY_FORMAT_SIZE_T is designed to select the correct format for the OS
2120 ``printf`` function, whereas PyString_FromFormat has an independent
2121 implementation and uses "%zd" on all platforms for size_t values.
2122 This makes a difference on win64, where ``printf`` needs "%Id" to display
2123 64bit values.

Benjamin Peterson97179b02008-09-09 20:55:01 +00002125- Issue #3634: _weakref.ref(Exception).__init__() gave invalid return value on

2129 object; previously an int would be returned for small values. the __long__
2130 method is allowed to return either an int or a long, but the behaviour of
2131 float objects should not change to respect backward compatibility.

Amaury Forgeot d'Arc3571fbf2008-09-01 19:52:00 +00002133- Issue #3751: str.rpartition would perform a left-partition when called with

Vinay Sajip35e3b032008-09-01 14:33:59 +00002139 PyArg_ParseTuple and friends, which occurred when the argument for "s*"
Antoine Pitroud4ae97b2008-08-29 18:39:48 +00002140 was correctly parsed but parsing of subsequent arguments failed.
2141
Vinay Sajip35e3b032008-09-01 14:33:59 +00002142- Issue #2534: speed up isinstance() and issubclass() by 50-70%, so as to
Antoine Pitrou0668c622008-08-26 22:42:08 +00002143 match Python 2.5 speed despite the __instancecheck__ / __subclasscheck__
2144 mechanism. In the process, fix a bug where isinstance() and issubclass(),
2145 when given a tuple of classes as second argument, were looking up
2146 __instancecheck__ / __subclasscheck__ on the tuple rather than on each
2147 type object.
2148
Neal Norwitz18aa3882008-08-24 05:04:52 +00002149- Fix crashes on memory allocation failure found with failmalloc.

Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00002286What's New in Python 2.6 beta 3?
2287================================
2288
Barry Warsaw07a4a382008-08-21 01:15:08 +00002289*Release date: 20-Aug-2008*
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00002290
2291Core and Builtins
2292-----------------
2293
Guido van Rossumf8402962008-08-20 15:01:50 +00002294- Issue #1878: Remove Py_TPFLAGS_HAVE_VERSION_TAG from
2295 Py_TPFLAGS_DEFAULT when not building the core. This means 3rd party
2296 extensions do not automatically benefit from the class attribute
2297 cache; they will have to explicitly add Py_TPFLAGS_HAVE_VERSION_TAG
2298 to their tp_flags field if they care. This is a backwards
2299 compatibility feature; in 3.0, all types will use the cache by
2300 default.
2301
Benjamin Petersonf647dc12008-08-20 01:27:30 +00002302- Keyword arguments can now follow starred arguments. (``f(a, *args,
2303 keyword=23)`` is now valid syntax.)
2304
Thomas Heller0ad5ae02008-08-19 19:25:04 +00002305- ctypes function pointers that are COM methods have a boolean True
2306 value again.
2307
Martin v. Löwisf91d46a2008-08-12 14:49:50 +00002308- Issue #3139: Make buffer-interface thread-safe wrt. PyArg_ParseTuple,
2309 by denying s# to parse objects that have a releasebuffer procedure,
2310 and introducing s*.
2311
Georg Brandl1e13ea92008-08-11 09:07:59 +00002312- Issue #3537: Fix an assertion failure when an empty but presized dict
2313 object was stored in the freelist.
2314
Mark Dickinsonb6467572008-08-04 21:30:09 +00002315- Issue #1481296: Make long(float('nan')) and int(float('nan')) raise
2316 ValueError consistently across platforms.
2317
Amaury Forgeot d'Arc39fd6722008-07-31 21:28:03 +00002318- Issue #3479: On platforms where sizeof(int) is smaller than sizeof(long)
2319 (64bit Unix, for example), unichr() would truncate its argument and return
2320 u'\x00' for unichr(2**32). Now it properly raises an OverflowError.
2321
Neal Norwitze7d8be82008-07-31 17:17:14 +00002322- Apply security patches from Apple.
2323
Amaury Forgeot d'Arc246daed2008-07-31 00:42:16 +00002324- Issue #2542: Now that issubclass() may call arbitrary code, ensure that
2325 PyErr_ExceptionMatches returns 0 when an exception occurs there.
2326
Antoine Pitrou92f82162008-07-25 22:22:08 +00002327- Issue #1819: function calls with several named parameters are now on
2328 average 35% faster (as measured by pybench).
2329
Amaury Forgeot d'Arce4921fe2008-07-21 22:00:38 +00002330- Issue #2378: An unexpected UnboundLocalError or NameError could appear when
2331 the python debugger steps into a class statement: the free variables (local
2332 variables defined in an outer scope) would be deleted from the outer scope.
2333
Gregory P. Smith0470bab2008-07-22 04:46:32 +00002334- Issue #2620: Overflow checking when allocating or reallocating memory
2335 was not always being done properly in some python types and extension
2336 modules. PyMem_MALLOC, PyMem_REALLOC, PyMem_NEW and PyMem_RESIZE have
2337 all been updated to perform better checks and places in the code that
2338 would previously leak memory on the error path when such an allocation
2339 failed have been fixed.
2340
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00002341Library
2342-------
2343
Hirokazu Yamamoto838c79f2008-08-20 13:14:07 +00002344- Issue #3612: Added some missing basic types in ctypes.wintypes.
2345
Benjamin Petersone977ad42008-08-20 01:42:01 +00002346- The methods ``is_in_tuple()``, ``is_vararg()``, and ``is_keywordarg()`` of
2347 symtable.Symbol have been deprecated for removal in 3.0 and the next release.
2348
Amaury Forgeot d'Arc351ffb82008-08-18 19:23:47 +00002349- Issue #2234: distutils failed for some versions of the cygwin compiler. The
2350 version reported by these tools does not necessarily follow the python
2351 version numbering scheme, so the module is less strict when parsing it.
2352
Nick Coghlanf70385a2008-08-18 12:42:46 +00002353- Issue #2235: Added Py3k warnings for types which will become unhashable
2354 under the stricter __hash__ inheritance rules in 3.0. Several types
2355 which did not meet the rules for hash invariants and were already
2356 unhashable in 3.0 have now been explicitly flagged as unhashable in
2357 2.6 as well (collections.Mapping, collections.Set, unittest.TestSuite,
2358 xml.dom.minidom.NamedNodeMap, numbers.Number, UserList.UserList)
2359
Brett Cannon88f801d2008-08-18 00:46:22 +00002360- Update __all__ for cookielib, csv, os, urllib2, and weakref to include things
2361 imported into the module but exposed as part of the module's API.
2362
Brett Cannon7b96f072008-08-18 00:41:11 +00002363- Remove an unneeded import of abc.ABCMeta from 'inspect'.
2364
Brett Cannon46225e72008-08-18 00:36:52 +00002365- Remove unneeded imports of 'sys' and 'warnings' from 'io'.
2366
Brett Cannon25c9d6a2008-08-17 22:10:11 +00002367- Remove unneeded imports of 'warnings' from shelve, filecmp, and dummy_thread.
2368
Hirokazu Yamamoto41a81eb2008-08-17 13:10:46 +00002369- Issue #3575: Incremental decoder's decode function now takes bytearray
2370 by using 's*' instead of 't#'.
2371
Mark Dickinson3e4caeb2009-02-21 20:27:01 +00002372- Issue #2222: Fixed reference leak when occurred os.rename()
Hirokazu Yamamoto7f30a682008-08-17 09:46:56 +00002373 fails unicode conversion on 2nd parameter. (windows only)
2374
Facundo Batista94f243a2008-08-17 03:38:39 +00002375- Issue 2464. urllib2 now supports a malformation in the URL received
2376 in a redirect.
2377
Brett Cannonabe423e2008-08-16 21:47:07 +00002378- Silence the DeprecationWarning raised when importing mimetools in
Brett Cannon721b1452008-08-16 22:00:27 +00002379 BaseHTTPServer, cgi (and rfc822), httplib.
Brett Cannonabe423e2008-08-16 21:47:07 +00002380
Facundo Batistaeb90b782008-08-16 14:44:07 +00002381- Issue #2776: fixed small issue when handling an URL with double slash
2382 after a 302 response in the case of not going through a proxy.
2383
Antoine Pitroub90a8be2008-08-15 21:03:21 +00002384- Issue #2676: in the email package, content-type parsing was hanging on
2385 pathological input because of quadratic or exponential behaviour of a
2386 regular expression.
2387
Antoine Pitrou11ec65d2008-08-14 21:04:30 +00002388- Issue #3476: binary buffered reading through the new "io" library is now
2389 thread-safe.
2390
Brett Cannonbf3157b2008-08-14 05:00:03 +00002391- Silence the DeprecationWarning of rfc822 when it is imported by mimetools
2392 since mimetools itself is deprecated. Because modules are cached, all
2393 subsequent imports of rfc822 will not raise a visible DeprecationWarning.
2394
Antoine Pitrou9fcd4b32008-08-11 17:21:36 +00002395- Issue #3134: shutil referenced undefined WindowsError symbol.
2396
Robert Schuppenies14646332008-08-10 11:01:53 +00002397- Issue #1342811: Fix leak in Tkinter.Menu.delete. Commands associated to
2398 menu entries were not deleted.
2399
Brett Cannon83e81842008-08-09 23:30:55 +00002400- Copied the implementation of reduce() to _functools.reduce() to have a
2401 version that did not raise a DeprecationWarning under -3.
2402
Antoine Pitrou76b8bee2008-08-09 17:27:23 +00002403- Issue #3205: When iterating over a BZ2File fails allocating memory, raise
2404 a MemoryError rather than silently stop the iteration.
2405
Guido van Rossum59ce9012008-08-09 14:55:34 +00002406- Issue #3487: sre "bytecode" validator. Passing invalid "re-bytecode"
2407 to _sre.compile() will now be rejected. This should not affect anybody
2408 since the re.compile() function never generates invalid re-bytecode.
2409
Skip Montanaroa032bf42008-08-08 22:52:51 +00002410- Issue #3436: Make csv.DictReader's fieldnames attribute a property so that
2411 upon first access it can be automatically initialized from the csv file if
2412 it wasn't initialized during instantiation.
2413
Brett Cannon3aa2a492008-08-06 22:28:09 +00002414- Issue #2338: Create imp.reload() to help with transitioning to Python 3.0 as
2415 the reload() built-in has been removed.
2416
Brett Cannon7e30b672008-08-04 21:52:25 +00002417- Changed code in the following modules/packages to remove warnings raised
Brett Cannonc1b76e42008-08-09 23:06:16 +00002418 while running under the ``-3`` flag: aifc, asynchat, asyncore, bdb, bsddb,

2422 subprocess, sqlite3, tarfile, Tkinter, test.test_support, textwrap,
2423 threading, tokenize, traceback, urlparse, wsgiref, xml, xmlrpclib.
Brett Cannon7e30b672008-08-04 21:52:25 +00002424
Lars Gustäbel727bd0b2008-08-02 11:26:39 +00002425- Issue #3039: Fix tarfile.TarFileCompat.writestr() which always
2426 raised an AttributeError.
2427
Benjamin Peterson01a24322008-07-28 23:35:27 +00002428- Issue #2523: Fix quadratic behaviour when read()ing a binary file without
Antoine Pitroude781a42008-08-09 12:43:23 +00002429 asking for a specific length. This problem only affected files opened
2430 using the new "io" module, not the built-in open() function.
Benjamin Peterson01a24322008-07-28 23:35:27 +00002431
Mark Dickinsonfe84cce2008-07-27 06:39:07 +00002432- Issue #3449: Update decimal module to use most recent specification
2433 (v. 1.68) and tests (v. 2.58) from IBM.
2434
Skip Montanarof9ac43f2008-07-27 00:50:41 +00002435- Issue 3437: Bug fix in robotparser parsing of Allow: lines.

2443
2444- Issue #3303: Fix a crash in locale.strcoll() when calling it with
2445 invalid arguments.
2446
2447- Issue #3302: Fix several crashes when calling locale's gettext functions
2448 with None arguments.
2449
2450- Issue #3389: Allow resolving dotted names for handlers in logging
2451 configuration files.
2452
2453- Deprecate the sunaudio module for removal in Python 3.0.
2454
Antoine Pitrou5fdfa3e2008-07-25 19:42:26 +00002455- Issue #3394: zipfile.writestr sets external attributes when passed a
2456 file name rather than a ZipInfo instance, so files are extracted with
2457 mode 0600 rather than 000 under Unix.
2458
Gregory P. Smitha36f8fe2008-08-04 00:13:29 +00002459- Issue #1857: subprocess.Popen.poll gained an additional _deadstate keyword
2460 argument in python 2.5, this broke code that subclassed Popen to include its
2461 own poll method. Fixed my moving _deadstate to an _internal_poll method.

Nick Coghlan6e8fef02008-08-18 13:14:22 +00002471- Issue #2235: the C API function PyObject_HashNotImplemented and its
2472 interaction with the tp_hash slot (added in 2.6b2) are now documented
2473
Nick Coghlan2a0c2b12008-08-04 12:47:17 +00002474- Issue #643841: The language reference now provides more detailed
2475 coverage of the lookup process for special methods. The disclaimers
2476 regarding lack of coverage of new-style classes have also been
2477 removed, since the coverage is now fairly reasonable.

2481================================
2482
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00002483*Release date: 17-Jul-2008*

2486-----------------
2487
Georg Brandl3e483f62008-07-16 22:57:41 +00002488- Issue #3156: Fix inconsistent behavior of the bytearray type: all
2489 its methods now allow for items objects that can be converted to
2490 an integer using operator.index().
2491
Mark Dickinson64b7e502008-07-16 09:40:03 +00002492- Issue #3360: Fix incorrect parsing of '020000000000.0', which
2493 produced a ValueError instead of giving the correct float.
2494
Eric Smitha5fa5a22008-07-16 00:11:49 +00002495- Issue #3083: Add alternate (#) formatting for bin, oct, hex output
2496 for str.format(). This adds the prefix 0b, 0o, or 0x, respectively.
2497
Mark Dickinson7103aa42008-07-15 19:08:33 +00002498- Issue #3008: the float type has a new instance method 'float.hex'
2499 and a new class method 'float.fromhex' to convert floating-point
2500 numbers to and from hexadecimal strings, respectively.
2501
Nick Coghlan6d6bd442008-07-15 15:40:22 +00002502- Issue #2235: __hash__ is once again inherited by default. To allow
2503 collections.Hashable to remain meaningful in the presence of the
2504 default hash implementation (object.__hash__), it is now possible
2505 to explicit block inheritance of hash by setting __hash__=None at
2506 the Python level, or tp_hash=PyObject_HashNotImplemented at the C
2507 level.
2508
Nick Coghlanb028f502008-07-13 14:52:36 +00002509- Issue #3221: Issue a RuntimeWarning instead of raising SystemError if
2510 the parent module cannot be found while performing an absolute import.
2511 This means that an incorrectly defined __package__ attribute will
2512 now only prevent relative imports in that module rather than causing
2513 all imports from that module to fail.
2514
Nick Coghlan14ff9942008-07-08 14:21:42 +00002515- Issue #2517: Allow unicode messages in Exceptions again by correctly
2516 bypassing the instance dictionary when looking up __unicode__ on
2517 new-style classes.
2518
Amaury Forgeot d'Arcbdd941f2008-07-01 20:38:04 +00002519- Issue #3242: Fix a crash inside the print statement, if sys.stdout is
2520 set to a custom object whose write() method happens to install
2521 another file in sys.stdout.

2525 another thread's dictionary.
2526
Mark Dickinson1ec2fcd2008-06-20 14:53:43 +00002527- Issue #3004: Minor change to slice.indices(): the start and stop
2528 arguments are now treated identically, making the behaviour easier
2529 to describe and understand. For example, slice(None, -10,
2530 1).indices(9) now returns (0, 0, 1) instead of (0, -1, 1), and
2531 slice(None, 10, -1).indices(10) returns (9, 9, -1) instead of (9,
2532 10, -1).
2533
Georg Brandl278fc502008-07-19 12:46:12 +00002534- Issue #3219: Calling a function with repeated keyword arguments,
2535 f(a=2, a=23), would not cause a syntax error. This was a regression
2536 from 2.4 caused by the switch to the new compiler.

Georg Brandl5cc774e2008-06-11 20:28:06 +00002986 PPC64 and x86_64 support in one binary).
Ronald Oussoren5640ce22008-06-05 12:58:24 +00002987
2988 This is controlled by the configure argument ``--with-universal-archs``:
2989
2990 - ``--with-universal-archs=all``: install 4-way universal
2991
2992 - ``--with-universal-archs=32-bit``: install 2-way universal, 32-bit (the default)
2993
2994 - ``--with-universal-archs=64-bit``: install 2-way universal, 64-bit
2995

Georg Brandl3ee81df2008-05-17 18:14:43 +00003048- Issue #1631171: Re-implement the 'warnings' module in C (the
3049 original Python code has been kept as backup). This will allow for
3050 using the 'warning's machinery in such places as the parser where
3051 use of pure Python code is not possible. Both the ``showarning()``
3052 and ``formatwarning()`` gain an optional 'line' argument which is
3053 not called by default for backwards-compatibility reasons. Setting
3054 ``warnings.showwarning()`` to an implementation that lacks support
3055 for the ``line`` argument will raise a DeprecationWarning.

Georg Brandl3ee81df2008-05-17 18:14:43 +00003110- Issue #2385: distutils.core.run_script() makes __file__ available,
3111 so the controlled environment will more closely mirror the typical
3112 script environment. This supports setup.py scripts that refer to
3113 data files.

Georg Brandl3ee81df2008-05-17 18:14:43 +00003118- Issue #2550: The approach used by client/server code for obtaining
3119 ports to listen on in network-oriented tests has been refined in an
3120 effort to facilitate running multiple instances of the entire
3121 regression test suite in parallel without issue.
3122 test_support.bind_port() has been fixed such that it will always
3123 return a unique port -- which wasn't always the case with the
3124 previous implementation, especially if socket options had been set
3125 that affected address reuse (i.e. SO_REUSEADDR, SO_REUSEPORT). The
3126 new implementation of bind_port() will actually raise an exception
3127 if it is passed an AF_INET/SOCK_STREAM socket with either the
3128 SO_REUSEADDR or SO_REUSEPORT socket option set. Furthermore, if
3129 available, bind_port() will set the SO_EXCLUSIVEADDRUSE option on
3130 the socket it's been passed. This currently only applies to
3131 Windows. This option prevents any other sockets from binding to the
3132 host/port we've bound to, thus removing the possibility of the
3133 'non-deterministic' behaviour, as Microsoft puts it, that occurs
3134 when a second SOCK_STREAM socket binds and accepts to a host/port
3135 that's already been bound by another socket. The optional preferred
3136 port parameter to bind_port() has been removed. Under no
3137 circumstances should tests be hard coding ports!
3138
3139 test_support.find_unused_port() has also been introduced, which will
3140 pass a temporary socket object to bind_port() in order to obtain an
3141 unused port. The temporary socket object is then closed and
3142 deleted, and the port is returned. This method should only be used
3143 for obtaining an unused port in order to pass to an external program
3144 (i.e. the -accept [port] argument to openssl's s_server mode) or as
3145 a parameter to a server-oriented class that doesn't give you direct
3146 access to the underlying socket used.
3147
3148 Finally, test_support.HOST has been introduced, which should be used
3149 for the host argument of any relevant socket calls (i.e. bind and
3150 connect).
Trent Nelsone41b0062008-04-08 23:47:30 +00003151
3152 The following tests were updated to following the new conventions:
Georg Brandl3ee81df2008-05-17 18:14:43 +00003153 test_socket, test_smtplib, test_asyncore, test_ssl, test_httplib,
Trent Nelsone41b0062008-04-08 23:47:30 +00003154 test_poplib, test_ftplib, test_telnetlib, test_socketserver,
3155 test_asynchat and test_socket_ssl.
3156
Georg Brandl3ee81df2008-05-17 18:14:43 +00003157 It is now possible for multiple instances of the regression test
3158 suite to run in parallel without issue.

3424Core and builtins
3425-----------------
3426
Fred Drakea8ee94b2008-03-01 02:45:07 +00003427- Issue #2051: pyc and pyo files are no longer created with permission
Barry Warsaw52973612008-03-01 02:23:38 +00003428 644. The mode is now inherited from the py file.
Christian Heimes40346852008-02-23 17:52:07 +00003429
Georg Brandlad61bc82008-02-23 15:11:18 +00003430- Issue #2067: file.__exit__() now calls subclasses' close() method.
3431
3432- Patch #1759: Backport of PEP 3129 class decorators.
Christian Heimes5224d282008-02-23 15:01:05 +00003433
Vinay Sajipb7edfc42008-04-02 21:10:23 +00003434- Issue #1881: An internal parser limit has been increased. Also see
Facundo Batistafc2d0102008-02-23 12:01:13 +00003435 issue 215555 for a discussion.
3436
Eric Smitha73fbe72008-02-23 03:09:44 +00003437- Added the future_builtins module, which contains hex() and oct().
3438 These are the PEP 3127 version of these functions, designed to be
3439 compatible with the hex() and oct() builtins from Python 3.0. They
3440 differ slightly in their output formats from the existing, unchanged
3441 Python 2.6 builtins. The expected usage of the future_builtins
3442 module is:
3443 from future_builtins import hex, oct
3444
Eric Smith7ef40bf2008-02-20 23:34:22 +00003445- Issue #1600: Modifed PyOS_ascii_formatd to use at most 2 digit
3446 exponents for exponents with absolute value < 100. Follows C99
3447 standard. This is a change on Windows, which would use 3 digits.
3448 Also, added 'n' to the formats that PyOS_ascii_formatd understands,
3449 so that any alterations it does to the resulting string will be
3450 available in stringlib/formatter.h (for float.__format__).
3451
Eric Smith5a3c1352008-02-19 13:21:56 +00003452- Implemented PEP 3101, Advanced String Formatting. This adds a new
3453 builtin format(); a format() method for str and unicode; a
3454 __format__() method to object, str, unicode, int, long, float, and
3455 datetime; the class string.Formatter; and the C API
3456 PyObject_Format().
3457
Georg Brandl3ee81df2008-05-17 18:14:43 +00003458- Fixed several potential crashes, all caused by specially crafted
3459 __del__ methods exploiting objects in temporarily inconsistent
3460 state.
Amaury Forgeot d'Arc632fad32008-02-16 20:55:24 +00003461
Vinay Sajipb7edfc42008-04-02 21:10:23 +00003462- Issue #2115: Important speedup in setting __slot__ attributes. Also
Georg Brandl3ee81df2008-05-17 18:14:43 +00003463 prevent a possible crash: an Abstract Base Class would try to access
3464 a slot on a registered virtual subclass.
Amaury Forgeot d'Arc60d6c7f2008-02-15 21:22:45 +00003465
Georg Brandl3ee81df2008-05-17 18:14:43 +00003466- Fixed repr() and str() of complex numbers with infinity or nan as
3467 real or imaginary part.
Christian Heimes2f0da532008-02-15 06:57:08 +00003468
Georg Brandl3ee81df2008-05-17 18:14:43 +00003469- Clear all free lists during a gc.collect() of the highest generation
3470 in order to allow pymalloc to free more arenas. Python may give back
3471 memory to the OS earlier.
Christian Heimes3b718a72008-02-14 12:47:33 +00003472
Georg Brandl3ee81df2008-05-17 18:14:43 +00003473- Issue #2045: Fix an infinite recursion triggered when printing a
3474 subclass of collections.defaultdict, if its default_factory is set
3475 to a bound method.
Amaury Forgeot d'Arcb01aa432008-02-08 00:56:02 +00003476
Christian Heimesf75dbef2008-02-08 00:11:31 +00003477- Fixed a minor memory leak in dictobject.c. The content of the free
3478 list was not freed on interpreter shutdown.
3479
Georg Brandl3ee81df2008-05-17 18:14:43 +00003480- Limit free list of method and builtin function objects to 256
3481 entries each.
Christian Heimes6075a822008-02-06 12:44:34 +00003482
Georg Brandl3ee81df2008-05-17 18:14:43 +00003483- Patch #1953: Added ``sys._compact_freelists()`` and the C API
3484 functions ``PyInt_CompactFreeList`` and ``PyFloat_CompactFreeList``
Christian Heimes422051a2008-02-04 18:00:12 +00003485 to compact the internal free lists of pre-allocted ints and floats.
3486
Georg Brandl3ee81df2008-05-17 18:14:43 +00003487- Issue #1983: Fixed return type of fork(), fork1() and forkpty()
3488 calls. Python expected the return type int but the fork familie
3489 returns pi_t.
Christian Heimes951cc0f2008-01-31 23:08:23 +00003490
Georg Brandl3ee81df2008-05-17 18:14:43 +00003491- Issue #1678380: Fix a bug that identifies 0j and -0j when they
3492 appear in the same code unit.
Mark Dickinson105be772008-01-31 22:17:37 +00003493
Georg Brandl3ee81df2008-05-17 18:14:43 +00003494- Issue #2025: Add tuple.count() and tuple.index() methods to comply
3495 with the collections.Sequence API.
Raymond Hettinger5b07ebc2008-02-07 00:54:20 +00003496

3498 linebreak detection
Christian Heimes4d4f2702008-01-30 11:32:37 +00003499
Georg Brandl3ee81df2008-05-17 18:14:43 +00003500- Added ``PyType_ClearCache()`` and ``sys._clear_type_cache`` to clear
3501 the internal lookup cache for ref leak tests.
Christian Heimes908caac2008-01-27 23:34:59 +00003502
Georg Brandl3ee81df2008-05-17 18:14:43 +00003503- Patch #1473257: generator objects gain a gi_code attribute. This is
3504 the same object as the func_code attribute of the function that
3505 produced the generator.
Georg Brandl0cdf9a32008-01-26 14:14:20 +00003506
Georg Brandl3ee81df2008-05-17 18:14:43 +00003507- Issue #1920: "while 0" statements were completely removed by the
3508 compiler, even in the presence of an "else" clause, which is
3509 supposed to be run when the condition is false. Now the compiler
3510 correctly emits bytecode for the "else" suite.
Amaury Forgeot d'Arc31eaafe2008-01-24 22:59:25 +00003511
Guido van Rossumeead05f2008-01-24 18:21:02 +00003512- A few crashers fixed: weakref_in_del.py (issue #1377858);
3513 loosing_dict_ref.py (issue #1303614, test67.py);
3514 borrowed_ref_[34].py (not in tracker).
3515
Vinay Sajipd7cf32e2008-01-24 12:43:33 +00003516- Issue #1069410: The "can't load dll" message box on Windows is
Christian Heimesb2302ba2008-01-23 17:15:06 +00003517 suppressed while an extension is loaded by calling SetErrorMode in
3518 dynload_win.c. The error is still reported properly.
3519
Georg Brandl3ee81df2008-05-17 18:14:43 +00003520- Issue #1915: Python compiles with --enable-unicode=no again. However
Christian Heimes082c9b02008-01-23 14:20:50 +00003521 several extension methods and modules do not work without unicode
3522 support.
3523
Georg Brandl26543b12008-01-21 18:36:51 +00003524- Issue #1882: when compiling code from a string, encoding cookies in the
3525 second line of code were not always recognized correctly.
3526
Georg Brandl14404b62008-01-19 19:27:05 +00003527- Issue #1679: "0x" was taken as a valid integer literal.
3528
Georg Brandl6caad7d2008-01-26 14:19:22 +00003529- Issue #1865: ``bytes`` as an alias for ``str`` and b"" as an alias "" were
Christian Heimes288e89a2008-01-18 18:24:07 +00003530 added.
3531
Christian Heimesc94e2b52008-01-14 04:13:37 +00003532- sys.float_info / PyFloat_GetInfo: The floating point information
3533 object was converted from a dict to a specialized structseq object.
3534
Georg Brandl3ee81df2008-05-17 18:14:43 +00003535- Patch #1816: Added sys.flags structseq. It exposes the status of
3536 most command line arguments and PYTHON* environment variables.
Christian Heimesf31b69f2008-01-14 03:42:48 +00003537
Georg Brandl3ee81df2008-05-17 18:14:43 +00003538- Objects/structseq.c: Implemented new structseq representation. The
3539 patch makes structseqs (e.g. the return value of os.stat) more
3540 readable.
Christian Heimes9c201962008-01-14 03:33:52 +00003541
Georg Brandl3ee81df2008-05-17 18:14:43 +00003542- Patch #1700288: added a type attribute cache that caches method
3543 accesses, resulting in speedups in heavily object-oriented code.
Amaury Forgeot d'Arce4c270c2008-01-14 00:29:41 +00003544

3551 envvar and sys.dont_write_bytecode attribute. All these can be set
3552 to forbid Python to attempt to write compiled bytecode files.
Georg Brandl2da0fce2008-01-07 17:09:35 +00003553
Georg Brandl3ee81df2008-05-17 18:14:43 +00003554- Improve some exception messages when Windows fails to load an
3555 extension module. Now we get for example '%1 is not a valid Win32
3556 application' instead of 'error code 193'.

Christian Heimes0a8143f2007-12-18 23:22:54 +00003563- Issue #1635: Platform independent creation and representation of NaN
Georg Brandl3ee81df2008-05-17 18:14:43 +00003564 and INF. float("nan"), float("inf") and float("-inf") now work on
3565 every platform with IEEE 754 semantics.
Christian Heimes0a8143f2007-12-18 23:22:54 +00003566
Georg Brandl3ee81df2008-05-17 18:14:43 +00003567- Compiler now generates simpler and faster code for dictionary
3568 literals. The oparg for BUILD_MAP now indicates an estimated
3569 dictionary size. There is a new opcode, STORE_MAP, for adding
3570 entries to the dictionary.

Georg Brandl3ee81df2008-05-17 18:14:43 +00003618- Issue #1686386: Tuple's tp_repr did not take into account the
3619 possibility of having a self-referential tuple, which is possible
3620 from C code. Nor did object's tp_str consider that a type's tp_str
3621 could do something that could lead to an inifinite recursion.
3622 Py_ReprEnter() and Py_EnterRecursiveCall(), respectively, fixed the
3623 issues.

Georg Brandl3ee81df2008-05-17 18:14:43 +00003625- Issue #1164: It was possible to trigger deadlock when using the
3626 'print' statement to write to a file since the GIL was not released
3627 as needed. Now PyObject_Print() does the right thing along with
3628 various tp_print implementations of the built-in types and those in
3629 the collections module.
Brett Cannon01531592007-09-17 03:28:34 +00003630
Georg Brandl3ee81df2008-05-17 18:14:43 +00003631- Issue #1147: Exceptions were directly allowing string exceptions in
3632 their throw() method even though string exceptions no longer
3633 allowed.
Brett Cannon4c20bc42007-09-11 21:02:28 +00003634
Georg Brandl3ee81df2008-05-17 18:14:43 +00003635- Issue #1096: Prevent a segfault from getting the repr of a very
3636 deeply nested list by using the recursion counter.
Brett Cannona0c05512007-09-10 21:38:27 +00003637
Brett Cannon1e534b52007-09-07 04:18:30 +00003638- Issue #1202533: Fix infinite recursion calls triggered by calls to
Georg Brandl3ee81df2008-05-17 18:14:43 +00003639 PyObject_Call() never calling back out to Python code to trigger
3640 recursion depth updates/checks. Required the creation of a static
3641 RuntimeError instance in case normalizing an exception put the
3642 recursion check value past its limit. Fixes crashers
3643 infinite_rec_(1|2|4|5).py.
Brett Cannon1e534b52007-09-07 04:18:30 +00003644

Neal Norwitz0ac60192007-05-27 04:08:54 +00003658- Add new attribute names for function objects. All the func_* become
Georg Brandl3ee81df2008-05-17 18:14:43 +00003659 __*__ attributes. (Some already existed, e.g., __doc__ and
3660 __name__.)
Neal Norwitz0ac60192007-05-27 04:08:54 +00003661
Neal Norwitz8b2bfbc2007-05-23 06:35:32 +00003662- Add -3 option to the interpreter to warn about features that are
3663 deprecated and will be changed/removed in Python 3.0.
3664
Georg Brandl2134e752007-05-21 20:34:16 +00003665- Patch #1686487: you can now pass any mapping after '**' in function
3666 calls.
3667
Collin Winter62903052007-05-18 23:11:24 +00003668- except clauses may now be spelled either "except E, target:" or
Georg Brandl3ee81df2008-05-17 18:14:43 +00003669 "except E as target:". This is to provide forwards compatibility
3670 with Python 3.0.
Collin Winter62903052007-05-18 23:11:24 +00003671
Brett Cannon229cee22007-05-05 01:34:02 +00003672- Deprecate BaseException.message as per PEP 352.
3673
Georg Brandl3ee81df2008-05-17 18:14:43 +00003674- Issue #1303614: don't expose object's __dict__ when the dict is
Armin Rigo9790a272007-05-02 19:23:31 +00003675 inherited from a builtin base.
3676
Vinay Sajip8549ce32007-05-06 17:53:37 +00003677- When __slots__ are set to a unicode string, make it work the same as
Neal Norwitzcbd9ee62007-04-14 05:25:50 +00003678 setting a plain string, ie don't expand to single letter identifiers.
3679
Raymond Hettinger13936692007-04-11 18:40:58 +00003680- Request #1191699: Slices can now be pickled.
3681
Raymond Hettinger4db5fe92007-04-12 04:10:00 +00003682- Request #1193128: str.translate() now allows a None argument for
3683 translations that only remove characters without re-mapping the
3684 remaining characters.
3685
Georg Brandl5cb76c12007-03-21 09:00:39 +00003686- Patch #1682205: a TypeError while unpacking an iterable is no longer
3687 masked by a generic one with the message "unpack non-sequence".
3688
Neal Norwitzaa754b72007-03-21 06:39:48 +00003689- Remove unused file Python/fmod.c.
3690
Guido van Rossum143b5642007-03-23 04:58:42 +00003691- Bug #1683368: The object.__init__() and object.__new__() methods are
3692 now stricter in rejecting excess arguments. The only time when
3693 either allows excess arguments is when it is not overridden and the
3694 other one is. For backwards compatibility, when both are
3695 overridden, it is a deprecation warning (for now; maybe a Py3k
Guido van Rossum234b1ff2007-03-23 19:39:01 +00003696 warning later). Also, type.__init__() insists on the same signature
3697 as supported by type.__new__().
Guido van Rossum143b5642007-03-23 04:58:42 +00003698
Georg Brandl3ee81df2008-05-17 18:14:43 +00003699- Patch #1675423: PyComplex_AsCComplex() now tries to convert an
3700 object to complex using its __complex__() method before falling back
3701 to the __float__() method. Therefore, the functions in the cmath
3702 module now can operate on objects that define a __complex__()
3703 method.
Georg Brandl2b869942007-03-17 16:08:45 +00003704
Georg Brandl3ee81df2008-05-17 18:14:43 +00003705- Patch #1623563: allow __class__ assignment for classes with
3706 __slots__. The old and the new class are still required to have the
3707 same slot names.

3714 its type.
Žiga Seilnacht20f43d32007-03-15 11:44:55 +00003715
Georg Brandl3ee81df2008-05-17 18:14:43 +00003716- Patch #1680015: Don't modify __slots__ tuple if it contains an

3720
Georg Brandl7b9c5552007-03-12 14:30:05 +00003721- Bug #1678647: write a newline after printing an exception in any
3722 case, even when converting the value to a string failed.
3723
Georg Brandl871f1bc2007-03-12 13:17:36 +00003724- The dir() function has been extended to call the __dir__() method on
Georg Brandl3ee81df2008-05-17 18:14:43 +00003725 its argument, if it exists. If not, it will work like before. This
3726 allows customizing the output of dir() in the presence of a
3727 __getattr__().

3736 parthensized forms. This means complex(repr(x)) now works instead of
3737 raising a ValueError.
Collin Wintere38051d2007-03-09 20:33:07 +00003738
Georg Brandlaa2321b2007-03-07 00:40:28 +00003739- Patch #703779: unset __file__ in __main__ after running a file. This
Georg Brandl3ee81df2008-05-17 18:14:43 +00003740 makes the filenames the warning module prints much more sensible
3741 when a PYTHONSTARTUP file is used.

Georg Brandl0fca97a2007-03-05 22:28:08 +00003754- Patch #1674228: when assigning a slice (old-style), check for the
3755 sq_ass_slice instead of the sq_slice slot.
3756
Georg Brandl3ee81df2008-05-17 18:14:43 +00003757- When printing an unraisable error, don't print exceptions. before
3758 the name. This duplicates the behavior whening normally printing
3759 exceptions.

Neal Norwitzdac090d2006-09-05 03:53:08 +00003859- Bug #1520864: unpacking singleton tuples in list comprehensions and
Georg Brandl3ee81df2008-05-17 18:14:43 +00003860 generator expressions (x for x, in ... ) works again. Fixing this

Georg Brandl3ee81df2008-05-17 18:14:43 +00004669- Issue #829951: In the smtplib module, SMTP.starttls() now complies
4670 with RFC 3207 and forgets any knowledge obtained from the server not
4671 obtained from the TLS negotiation itself. Patch contributed by Bill
4672 Fenner.
Gregory P. Smith2b3ba582008-01-17 08:03:17 +00004673
Georg Brandl3ee81df2008-05-17 18:14:43 +00004674- Issue #1339: The smtplib.SMTP class has been refactored a bit such
Gregory P. Smithbde4ae42008-01-17 08:35:49 +00004675 that the SMTP.starttls() caller no longer needs to call ehlo()
4676 beforehand. SMTP.starttls() now raises an exception of the server
Georg Brandl3ee81df2008-05-17 18:14:43 +00004677 does not claim to support starttls. Adds the
4678 SMTP.ehlo_or_helo_if_needed() method. Patch contributed by Bill
4679 Fenner.

4759 complex, tuple, list, dict, set, and frozenset. Formerly, it would
4760 silently miscode subclasses of those types. Now, it raises a
4761 ValueError instead.
Raymond Hettinger12e94202007-11-07 01:13:09 +00004762

Georg Brandl3ee81df2008-05-17 18:14:43 +00004777 time so that opening a database previously created with the DB_DUP
4778 or DB_DUPSORT flag set will keep the proper behavior on subsequent
4779 opens. Specifically: dictionary assignment to a DB object will
4780 replace all values for a given key when the database allows
4781 duplicate values. DB users should use DB.put(k, v) when they want
4782 to store duplicates; not DB[k] = v.
Gregory P. Smithec10a4a2007-11-05 02:32:26 +00004783

4789 characters with ASCII value less than 32. Also, it correctly quotes
4790 dots only if they occur on a single line, as opposed to the previous
4791 behavior of quoting dots if they are the second character of any
4792 line.
Georg Brandl4aef7272007-03-13 22:49:43 +00004793

5115-----
5116
Georg Brandl3ee81df2008-05-17 18:14:43 +00005117- Unified naming convention for free lists and their limits. All free
5118 lists in Object/ are named ``free_list``, the counter ``numfree``
5119 and the upper limit is a macro ``PyName_MAXFREELIST`` inside an
5120 #ifndef block.
Christian Heimes5b970ad2008-02-06 13:33:44 +00005121
Georg Brandl3ee81df2008-05-17 18:14:43 +00005122- ``PySet_Add()`` can now modify a newly created frozenset. Similarly
5123 to ``PyTuple_SetItem``, it can be used to populate a brand new
5124 frozenset; but it does not steal a reference to the added item.

5129 and _FormatV from Python 3.0. Made PyLong_AsSsize_t and
5130 PyLong_FromSsize_t public functions.
Georg Brandl6caad7d2008-01-26 14:19:22 +00005131
5132- Patch #1720595: add T_BOOL to the range of structmember types.
5133
5134- Issue #1534: Added ``PyFloat_GetMax()``, ``PyFloat_GetMin()`` and
5135 ``PyFloat_GetInfo()`` to the float API.
5136
Georg Brandl3ee81df2008-05-17 18:14:43 +00005137- Issue #1521: On 64bit platforms, using PyArgs_ParseTuple with the t#
5138 of w# format code incorrectly truncated the length to an int, even
5139 when PY_SSIZE_T_CLEAN is set. The str.decode method used to return
5140 incorrect results with huge strings.
Georg Brandl6caad7d2008-01-26 14:19:22 +00005141
Georg Brandl3ee81df2008-05-17 18:14:43 +00005142- Issue #1629: Renamed Py_Size, Py_Type and Py_Refcnt to Py_SIZE,

Georg Brandl3ee81df2008-05-17 18:14:43 +00005145- PEP 3123: Provide forward compatibility with Python 3.0, while
5146 keeping backwards compatibility. Add Py_Refcnt, Py_Type, Py_Size,
5147 and PyVarObject_HEAD_INIT.

5160- Fix some leftovers from the conversion from int to Py_ssize_t
5161 (relevant to strings and sequences of more than 2**31 items).
5162
5163- Make _PyGILState_NoteThreadState() static, it was not used anywhere
5164 outside of pystate.c and should not be necessary.
5165
Georg Brandl3ee81df2008-05-17 18:14:43 +00005166- ``PyImport_Import`` and ``PyImport_ImportModule`` now always do
5167 absolute imports. In earlier versions they might have used relative
5168 imports under some conditions.
Christian Heimes000a0742008-01-03 22:16:32 +00005169
Georg Brandl3ee81df2008-05-17 18:14:43 +00005170- Added case insensitive comparison methods ``PyOS_stricmp(char*,
5171 char*)`` and ``PyOS_strnicmp(char*, char*, Py_ssize_t)``.
Christian Heimes000a0742008-01-03 22:16:32 +00005172
Georg Brandl3ee81df2008-05-17 18:14:43 +00005173- Bug #1542693: remove semi-colon at end of PyImport_ImportModuleEx

Georg Brandl3ee81df2008-05-17 18:14:43 +00005180- Patch #1706: Drop support for Win9x, WinME and NT4. Python now
5181 requires Windows 2000 or greater. The _WINVER and NTDDI_VERSION
5182 macros are set to Win2k for x86/32bit builds and WinXP for AMD64
5183 builds.
Christian Heimes95d64472008-02-09 19:55:22 +00005184

Georg Brandl3ee81df2008-05-17 18:14:43 +00005198- Removed the macfs module. It had been deprecated since Python 2.5.
5199 This lead to the deprecation of macostools.touched() as it relied
5200 solely on macfs and was a no-op under OS X.
