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.

64
Tarek Ziadédc0f4872010-01-11 22:50:29 +000065- Issue #5372: Drop the reuse of .o files in Distutils' ccompiler (since

92
Benjamin Petersonecdae192010-01-04 00:43:01 +000093- The __complex__ method is now looked up on the class of instances to make it
94 consistent with other special methods.
95
Antoine Pitrou5b7139a2010-01-02 21:12:58 +000096- Issue #7462: Implement the stringlib fast search algorithm for the `rfind`,
97 `rindex`, `rsplit` and `rpartition` methods. Patch by Florent Xicluna.
98
Mark Dickinson1b34d252010-01-01 17:27:30 +000099- Issue #5080: A number of functions and methods previously produced a
100 DeprecationWarning when passed a float argument where an integer was
101 expected. These functions and methods now raise TypeError instead.
102 The majority of the effects of this change are in the extension
103 modules, but some core functions and methods are affected: notably
104 the 'chr', 'range' and 'xrange' builtins, and many unicode/str
105 methods.
106
Benjamin Peterson0f02d392009-12-30 19:34:10 +0000107- Issue #7604: Deleting an unset slotted attribute did not raise an
108 AttributeError.

Mark Dickinson99d652e2009-12-30 12:12:23 +0000110- Issue #7534: Fix handling of IEEE specials (infinities, nans,
111 negative zero) in ** operator. The behaviour now conforms to that
112 described in C99 Annex F.
113
Amaury Forgeot d'Arcc8a2ce72009-12-29 23:06:17 +0000114- Issue #7579: the msvcrt module now has docstrings for all its functions.
115
Amaury Forgeot d'Arc8645a5c2009-12-29 22:03:38 +0000116- Issue #7413: Passing '\0' as the separator to datetime.datetime.isoformat()
117 used to drop the time part of the result.
118
Mark Dickinson46572832009-12-27 14:55:57 +0000119- Issue #1811: improve accuracy and cross-platform consistency for
120 true division of integers: the result of a/b is now correctly
121 rounded for ints a and b (at least on IEEE 754 platforms), and in
122 particular does not depend on the internal representation of a long.
123
Ezio Melottif84caf42009-12-24 22:25:17 +0000124- Issue #6108: unicode(exception) and str(exception) should return the same
125 message when only __str__ (and not __unicode__) is overridden in the subclass.
126
Ronald Oussoren92919a62009-12-24 13:30:58 +0000127- Issue #6834: replace the implementation for the 'python' and 'pythonw'
128 executables on OSX.
129
130 These executables now work properly with the arch(1) command:
131 ``arch -ppc python`` will start a universal binary version of python
132 in PPC mode (unlike previous releases).
133
R. David Murray0a0a1a82009-12-14 16:28:26 +0000134- Issue #1680159: unicode coercion during an 'in' operation no longer masks
135 the underlying error when the coercion fails for the left hand operand.
136
Benjamin Peterson4895af42009-12-13 16:36:53 +0000137- Issue #7491: Metaclass's __cmp__ method was ignored.
138
Antoine Pitrou2a08b422009-12-13 16:18:14 +0000139- Issue #7466: segmentation fault when the garbage collector is called

148 by Arfrever.
149
Antoine Pitrou80157252010-01-08 19:20:17 +0000150- Issue #7092: Remove py3k warning when importing cPickle. 2to3 handles
151 renaming of `cPickle` to `pickle`. The warning was annoying since there's
152 no alternative to cPickle if you care about performance. Patch by Florent
153 Xicluna.
154

163 speedups by wrapping it in an `io.BufferedReader`. Patch by Nir Aides.
164
165- Issue #3972: httplib.HTTPConnection now accepts an optional source_address
Gregory P. Smith9d325212010-01-03 02:06:07 +0000166 parameter to allow specifying where your connections come from.

185
Benjamin Petersonddd392c2009-12-13 19:19:07 +0000186- Issue #7349: Make methods of file objects in the io module accept None as an

188 the same as passing no argument.
189
Benjamin Petersonc4771d22009-12-13 17:31:31 +0000190- Issue #7348: StringIO.StringIO.readline(-1) now acts as if it got no argument

Amaury Forgeot d'Arcd7288712009-12-01 21:51:04 +0000261- Issue #7419: setlocale() could crash the interpreter on Windows when called
262 with invalid values.
263
Eric Smithc4ab8332009-11-29 17:40:57 +0000264- Issue #3382: 'F' formatting for float and complex now convert the
265 result to upper case. This only affects 'inf' and 'nan', since 'f'
266 no longer converts to 'g' for large values.
Amaury Forgeot d'Arcd7288712009-12-01 21:51:04 +0000267
Mark Dickinson9dd5e162009-11-23 20:54:09 +0000268- Remove switch from "%f" formatting to "%g" formatting for floats
269 larger than 1e50 in absolute value.
270
Mark Dickinson18cfada2009-11-23 18:46:41 +0000271- Remove restrictions on precision when formatting floats. E.g.,
272 "%.120g" % 1e-100 used to raise OverflowError, but now gives the
273 requested 120 significant digits instead.
274
Benjamin Peterson89b1a5c2009-11-19 22:58:01 +0000275- Add Py3k warnings for parameter names in parenthesis.

Ronald Oussoren315cd0c2009-11-19 16:25:21 +0000279- Issue #7085: Fix crash when importing some extensions in a thread
280 on MacOSX 10.6.
281
Mark Dickinsonb678de82009-11-19 18:41:49 +0000282- Issue #7117: repr(x) for a float x returns a result based on the
283 shortest decimal string that's guaranteed to round back to x under
284 correct rounding (with round-half-to-even rounding mode).
285 Previously it gave a string based on rounding x to 17 decimal digits.
286 repr(x) for a complex number behaves similarly. On platforms where
287 the correctly-rounded strtod and dtoa code is not supported (see below),
288 repr is unchanged.
289
290- Issue #7117: On almost all platforms: float-to-string and
291 string-to-float conversions within Python are now correctly rounded.
292 Places these conversions occur include: str for floats and complex
293 numbers; the float and complex constructors; old-style and new-style
294 numeric formatting; serialization and deserialization of floats and
295 complex numbers using marshal, pickle and json; parsing of float and
296 imaginary literals in Python code; Decimal-to-float conversion.
297
298 The conversions use a Python-adapted version of David Gay's
299 well-known dtoa.c, providing correctly-rounded strtod and dtoa C
300 functions. This code is supported on Windows, and on Unix-like
301 platforms using gcc, icc or suncc as the C compiler. There may be a
302 small number of platforms on which correct operation of this code
303 cannot be guaranteed, so the code is not used: notably, this applies
304 to platforms where the C double format is not IEEE 754 binary64, and
305 to platforms on x86 hardware where the x87 FPU is set to 64-bit
306 precision and Python's configure script is unable to determine how
307 to change the FPU precision. On these platforms conversions use the
308 platform strtod and dtoa, as before.

Mark Dickinsonbd15a062009-11-18 19:33:35 +0000310- Issue #7117: Backport round implementation from Python 3.x. round
Mark Dickinsonb678de82009-11-19 18:41:49 +0000311 now uses the correctly-rounded string <-> float conversions
312 described above (when available), and so produces correctly rounded
313 results that will display nicely under the float repr. There are
314 two related small changes: (1) round now accepts any class with an
315 __index__ method for its second argument (but no longer accepts
Mark Dickinsonbd15a062009-11-18 19:33:35 +0000316 floats for the second argument), and (2) an excessively large second
317 integer argument (e.g., round(1.234, 10**100)) no longer raises an
318 exception.

464 didn't match that of float('-nan').
465
Eric Smitha985a3a2009-05-05 18:26:08 +0000466- Issue #5920: For float.__format__, change the behavior with the
467 empty presentation type (that is, not one of 'e', 'f', 'g', or 'n')
468 to be like 'g' but with at least one decimal point and with a
469 default precision of 12. Previously, the behavior the same but with
470 a default precision of 6. This more closely matches str(), and
471 reduces surprises when adding alignment flags to the empty
472 presentation type. This also affects the new complex.__format__ in
473 the same way.

Antoine Pitrou4c5ecb72009-01-09 21:40:55 +0000608- Issue #4074: Change the criteria for doing a full garbage collection (i.e.
609 collecting the oldest generation) so that allocating lots of objects without
610 destroying them does not show quadratic performance. Based on a proposal by

615
Antoine Pitroue96d4ea2009-01-06 18:10:47 +0000616- Issue #1180193: When importing a module from a .pyc (or .pyo) file with
617 an existing .py counterpart, override the co_filename attributes of all
618 code objects if the original filename is obsolete (which can happen if the
619 file has been renamed, moved, or if it is accessed through different paths).
620 Patch by Ziga Seilnacht and Jean-Paul Calderone.

Hirokazu Yamamoto99a1b202009-01-01 15:45:39 +0000624- Issue #4797: IOError.filename was not set when _fileio.FileIO failed to open
625 file with `str' filename on Windows.
626
Antoine Pitrouaa687902009-01-01 14:11:22 +0000627- Issue #3680: Reference cycles created through a dict, set or deque iterator
628 did not get collected.
629
Nick Coghlan180e4002008-12-30 01:18:48 +0000630- Issue #4701: PyObject_Hash now implicitly calls PyType_Ready on types

632
Benjamin Peterson7af65562008-12-29 17:56:58 +0000633- Issue #4764: With io.open, IOError.filename is set when trying to open a

641
Skip Montanarof205c132008-12-23 03:30:15 +0000642- Added test case to ensure attempts to read from a file opened for writing

656
Jeffrey Yasskinffd42cf2008-12-10 07:35:02 +0000657- Issue #4597: Fixed several opcodes that weren't always propagating
658 exceptions.
659
Mark Dickinson826f3fe2008-12-05 21:55:28 +0000660- Issue #4445: Replace "sizeof(PyStringObject)" with
661 "offsetof(PyStringObject, ob_sval) + 1" when allocating memory for
662 str instances. On a typical machine this saves 3 bytes of memory
663 (on average) per string allocation.
664
Amaury Forgeot d'Arcdc619012008-11-22 20:01:18 +0000665- Issue #3996: On Windows, the PyOS_CheckStack function would cause the
666 interpreter to abort ("Fatal Python error: Could not reset the stack!")
667 instead of throwing a MemoryError.
668
Raymond Hettinger7989a4d2008-12-03 15:42:10 +0000669- Issue #3689: The list reversed iterator now supports __length_hint__
670 instead of __len__. Behavior now matches other reversed iterators.
671
Benjamin Petersonc078f922008-11-21 22:27:24 +0000672- Issue #4367: Python would segfault during compiling when the unicodedata
673 module couldn't be imported and \N escapes were present.
674
Vinay Sajip213faca2008-12-03 23:22:58 +0000675- Issue #4233: Changed semantic of ``_fileio.FileIO``'s ``close()``
Amaury Forgeot d'Arc32265652008-11-20 23:34:31 +0000676 method on file objects with closefd=False. The file descriptor is still
677 kept open but the file object behaves like a closed file. The ``FileIO``
678 object also got a new readonly attribute ``closefd``.
679
Benjamin Peterson46cc6d12008-11-19 21:49:09 +0000680- Issue #4348: Some bytearray methods returned that didn't cause any change to
681 the bytearray, returned the same bytearray instead of a copy.
682
Amaury Forgeot d'Arc7cfe7ea2008-11-18 22:19:37 +0000683- Issue #4317: Fixed a crash in the imageop.rgb2rgb8() function.
684
Benjamin Peterson273c2332008-11-17 22:39:09 +0000685- Issue #4230: If ``__getattr__`` is a descriptor, it now functions correctly.
686
Benjamin Peterson6624a9f2008-11-03 15:14:51 +0000687- Issue #4048: The parser module now correctly validates relative imports.
688
Benjamin Petersondcee09d2008-10-31 02:16:05 +0000689- Issue #4225: ``from __future__ import unicode_literals`` didn't work in an

691
Amaury Forgeot d'Arc69a9c5b2008-10-30 21:18:34 +0000692- Issue #4176: Fixed a crash when pickling an object which ``__reduce__``
693 method does not return iterators for the 4th and 5th items.
694
Benjamin Petersonbdca9422008-10-26 20:21:13 +0000695- Issue #4209: Enabling unicode_literals and the print_function in the same
696 __future__ import didn't work.
697
Benjamin Peterson399b1fe2008-10-25 02:53:28 +0000698- Using ``nonlocal`` as a variable name will now raise a Py3k SyntaxWarning
Georg Brandl7fb00ad2008-10-25 07:00:52 +0000699 because it is a reserved word in 3.x.
Benjamin Peterson399b1fe2008-10-25 02:53:28 +0000700
Hirokazu Yamamoto10a018c2008-10-09 10:00:30 +0000701- On windows, os.chdir given unicode was not working if GetCurrentDirectoryW
702 returned a path longer than MAX_PATH. (But It's doubtful this code path is
703 really executed because I cannot move to such directory on win2k)
704
Amaury Forgeot d'Arcd78b9dc2008-10-07 20:32:10 +0000705- Issue #4069: When set.remove(element) is used with a set element, the element
706 is temporarily replaced with an equivalent frozenset. But the eventual
707 KeyError would always report the empty frozenset([]) as the missing key. Now
708 it correctly refers to the initial element.
709
Antoine Pitrouae5bece2008-12-06 21:29:24 +0000710- Issue #4509: Various issues surrounding resize of bytearray objects to
711 which there are buffer exports.
712

721
Matthias Klose91a3b9e2009-04-05 21:19:13 +0000722- Issue #1113244: Py_XINCREF, Py_DECREF, Py_XDECREF: Add `do { ... } while (0)'
723 to avoid compiler warnings.

Gregory P. Smith2b3eb372009-04-05 23:48:26 +0000725- Issue #5705: os.setuid() would not accept values > 2**31-1 but pwd.getpwnam()
726 returned them on 64bit platforms.
727
Walter Dörwalded960ac2009-05-03 22:36:33 +0000728- Issue #5108: Handle %s like %S and %R in PyUnicode_FromFormatV(): Call
729 PyUnicode_DecodeUTF8() once, remember the result and output it in a second
730 step. This avoids problems with counting UTF-8 bytes that ignores the effect
731 of using the replace error handler in PyUnicode_DecodeUTF8().
732
Walter Dörwald726ba8e2009-05-06 14:32:35 +0000733- Issue #3739: The unicode-internal encoder now reports the number of characters
734 consumed like any other encoder (instead of the number of bytes).
735
Benjamin Peterson91c12eb2009-12-03 02:52:39 +0000736- Issue #2422: When compiled with the ``--with-valgrind`` option, the
737 pymalloc allocator will be automatically disabled when running under
738 Valgrind. This gives improved memory leak detection when running
739 under Valgrind, while taking advantage of pymalloc at other times.

Nick Coghlan49868cb2009-11-15 07:30:34 +0000808- Issue #6816: runpy now provides a run_path function that allows Python code
809 to execute file paths that refer to source or compiled Python files as well
810 as zipfiles, directories and other valid sys.path entries that contain a

1973 primitives such as Lock, RLock, Condition, Event and Semaphore.
1974
Antoine Pitrou59c44f32009-10-30 17:07:08 +00001975- Issue #7222: Make thread "reaping" more reliable so that reference
1976 leak-chasing test runs give sensible results. The previous method of
1977 reaping threads could return successfully while some Thread objects were
1978 still referenced. This also introduces a new private function:
1979 :func:`thread._count()`.

1983
Antoine Pitrou58d2f262009-10-10 20:52:11 +00001984- Issue #7055: test___all__ now greedily detects all modules which have an
1985 __all__ attribute, rather than using a hardcoded and incomplete list.
1986
R. David Murray14dcd432009-10-14 13:58:07 +00001987- Issue #7058: Added save/restore for things like sys.argv and cwd to
1988 runtest_inner in regrtest, with warnings if the called test modifies them,
1989 and a new section in the summary report at the end.

1994 off the trailing 0 in the version number.
1995
Guilherme Polo7f146ab2009-06-21 17:22:50 +00001996- Issue #5450: Moved tests involving loading tk from Lib/test/test_tcl to
1997 Lib/lib-tk/test/test_tkinter/test_loadtk. With this, these tests demonstrate
1998 the same behaviour as test_ttkguionly (and now also test_tk) which is to
1999 skip the tests if DISPLAY is defined but can't be used.
2000
Antoine Pitrou4698d992009-05-31 14:20:14 +00002001- Issue #6152: New option '-j'/'--multiprocess' for regrtest allows running
2002 regression tests in parallel, shortening the total runtime.

Nick Coghlan5533ff62009-04-22 15:26:04 +00002004- Issue #5354: New test support function import_fresh_module() makes
2005 it easy to import both normal and optimised versions of modules.
2006 test_heapq and test_warnings have been adjusted to use it, tests for
2007 other modules with both C and Python implementations in the stdlib
2008 can be adjusted to use it over time.

R. David Murray41448c52009-03-31 19:57:24 +00002016- regrtest no longer treats ImportError as equivalent to SkipTest. Imports
Vinay Sajip22aa4bb2009-04-16 19:15:49 +00002017 that should cause a test to be skipped are now done using import_module
R. David Murray41448c52009-03-31 19:57:24 +00002018 from test support, which does the conversion.

Martin v. Löwis9fa5a282008-09-11 06:53:30 +00002119- Issue #3642: Suppress warning in obmalloc when size_t is larger than uint.
2120
Amaury Forgeot d'Arc05e34492008-09-10 22:04:45 +00002121- Issue #3743: In a few places, PY_FORMAT_SIZE_T was incorrectly used with
2122 PyString_FromFormat or PyErr_Format to display size_t values. The macro
2123 PY_FORMAT_SIZE_T is designed to select the correct format for the OS
2124 ``printf`` function, whereas PyString_FromFormat has an independent
2125 implementation and uses "%zd" on all platforms for size_t values.
2126 This makes a difference on win64, where ``printf`` needs "%Id" to display
2127 64bit values.

Benjamin Peterson97179b02008-09-09 20:55:01 +00002129- Issue #3634: _weakref.ref(Exception).__init__() gave invalid return value on

2133 object; previously an int would be returned for small values. the __long__
2134 method is allowed to return either an int or a long, but the behaviour of
2135 float objects should not change to respect backward compatibility.

Amaury Forgeot d'Arc3571fbf2008-09-01 19:52:00 +00002137- Issue #3751: str.rpartition would perform a left-partition when called with

Vinay Sajip35e3b032008-09-01 14:33:59 +00002143 PyArg_ParseTuple and friends, which occurred when the argument for "s*"
Antoine Pitroud4ae97b2008-08-29 18:39:48 +00002144 was correctly parsed but parsing of subsequent arguments failed.
2145
Vinay Sajip35e3b032008-09-01 14:33:59 +00002146- Issue #2534: speed up isinstance() and issubclass() by 50-70%, so as to
Antoine Pitrou0668c622008-08-26 22:42:08 +00002147 match Python 2.5 speed despite the __instancecheck__ / __subclasscheck__
2148 mechanism. In the process, fix a bug where isinstance() and issubclass(),
2149 when given a tuple of classes as second argument, were looking up
2150 __instancecheck__ / __subclasscheck__ on the tuple rather than on each
2151 type object.
2152
Neal Norwitz18aa3882008-08-24 05:04:52 +00002153- Fix crashes on memory allocation failure found with failmalloc.

Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00002290What's New in Python 2.6 beta 3?
2291================================
2292
Barry Warsaw07a4a382008-08-21 01:15:08 +00002293*Release date: 20-Aug-2008*
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00002294
2295Core and Builtins
2296-----------------
2297
Guido van Rossumf8402962008-08-20 15:01:50 +00002298- Issue #1878: Remove Py_TPFLAGS_HAVE_VERSION_TAG from
2299 Py_TPFLAGS_DEFAULT when not building the core. This means 3rd party
2300 extensions do not automatically benefit from the class attribute
2301 cache; they will have to explicitly add Py_TPFLAGS_HAVE_VERSION_TAG
2302 to their tp_flags field if they care. This is a backwards
2303 compatibility feature; in 3.0, all types will use the cache by
2304 default.
2305
Benjamin Petersonf647dc12008-08-20 01:27:30 +00002306- Keyword arguments can now follow starred arguments. (``f(a, *args,
2307 keyword=23)`` is now valid syntax.)
2308
Thomas Heller0ad5ae02008-08-19 19:25:04 +00002309- ctypes function pointers that are COM methods have a boolean True
2310 value again.
2311
Martin v. Löwisf91d46a2008-08-12 14:49:50 +00002312- Issue #3139: Make buffer-interface thread-safe wrt. PyArg_ParseTuple,
2313 by denying s# to parse objects that have a releasebuffer procedure,
2314 and introducing s*.
2315
Georg Brandl1e13ea92008-08-11 09:07:59 +00002316- Issue #3537: Fix an assertion failure when an empty but presized dict
2317 object was stored in the freelist.
2318
Mark Dickinsonb6467572008-08-04 21:30:09 +00002319- Issue #1481296: Make long(float('nan')) and int(float('nan')) raise
2320 ValueError consistently across platforms.
2321
Amaury Forgeot d'Arc39fd6722008-07-31 21:28:03 +00002322- Issue #3479: On platforms where sizeof(int) is smaller than sizeof(long)
2323 (64bit Unix, for example), unichr() would truncate its argument and return
2324 u'\x00' for unichr(2**32). Now it properly raises an OverflowError.
2325
Neal Norwitze7d8be82008-07-31 17:17:14 +00002326- Apply security patches from Apple.
2327
Amaury Forgeot d'Arc246daed2008-07-31 00:42:16 +00002328- Issue #2542: Now that issubclass() may call arbitrary code, ensure that
2329 PyErr_ExceptionMatches returns 0 when an exception occurs there.
2330
Antoine Pitrou92f82162008-07-25 22:22:08 +00002331- Issue #1819: function calls with several named parameters are now on
2332 average 35% faster (as measured by pybench).
2333
Amaury Forgeot d'Arce4921fe2008-07-21 22:00:38 +00002334- Issue #2378: An unexpected UnboundLocalError or NameError could appear when
2335 the python debugger steps into a class statement: the free variables (local
2336 variables defined in an outer scope) would be deleted from the outer scope.
2337
Gregory P. Smith0470bab2008-07-22 04:46:32 +00002338- Issue #2620: Overflow checking when allocating or reallocating memory
2339 was not always being done properly in some python types and extension
2340 modules. PyMem_MALLOC, PyMem_REALLOC, PyMem_NEW and PyMem_RESIZE have
2341 all been updated to perform better checks and places in the code that
2342 would previously leak memory on the error path when such an allocation
2343 failed have been fixed.
2344
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00002345Library
2346-------
2347
Hirokazu Yamamoto838c79f2008-08-20 13:14:07 +00002348- Issue #3612: Added some missing basic types in ctypes.wintypes.
2349
Benjamin Petersone977ad42008-08-20 01:42:01 +00002350- The methods ``is_in_tuple()``, ``is_vararg()``, and ``is_keywordarg()`` of
2351 symtable.Symbol have been deprecated for removal in 3.0 and the next release.
2352
Amaury Forgeot d'Arc351ffb82008-08-18 19:23:47 +00002353- Issue #2234: distutils failed for some versions of the cygwin compiler. The
2354 version reported by these tools does not necessarily follow the python
2355 version numbering scheme, so the module is less strict when parsing it.
2356
Nick Coghlanf70385a2008-08-18 12:42:46 +00002357- Issue #2235: Added Py3k warnings for types which will become unhashable
2358 under the stricter __hash__ inheritance rules in 3.0. Several types
2359 which did not meet the rules for hash invariants and were already
2360 unhashable in 3.0 have now been explicitly flagged as unhashable in
2361 2.6 as well (collections.Mapping, collections.Set, unittest.TestSuite,
2362 xml.dom.minidom.NamedNodeMap, numbers.Number, UserList.UserList)
2363
Brett Cannon88f801d2008-08-18 00:46:22 +00002364- Update __all__ for cookielib, csv, os, urllib2, and weakref to include things
2365 imported into the module but exposed as part of the module's API.
2366
Brett Cannon7b96f072008-08-18 00:41:11 +00002367- Remove an unneeded import of abc.ABCMeta from 'inspect'.
2368
Brett Cannon46225e72008-08-18 00:36:52 +00002369- Remove unneeded imports of 'sys' and 'warnings' from 'io'.
2370
Brett Cannon25c9d6a2008-08-17 22:10:11 +00002371- Remove unneeded imports of 'warnings' from shelve, filecmp, and dummy_thread.
2372
Hirokazu Yamamoto41a81eb2008-08-17 13:10:46 +00002373- Issue #3575: Incremental decoder's decode function now takes bytearray
2374 by using 's*' instead of 't#'.
2375
Mark Dickinson3e4caeb2009-02-21 20:27:01 +00002376- Issue #2222: Fixed reference leak when occurred os.rename()
Hirokazu Yamamoto7f30a682008-08-17 09:46:56 +00002377 fails unicode conversion on 2nd parameter. (windows only)
2378
Facundo Batista94f243a2008-08-17 03:38:39 +00002379- Issue 2464. urllib2 now supports a malformation in the URL received
2380 in a redirect.
2381
Brett Cannonabe423e2008-08-16 21:47:07 +00002382- Silence the DeprecationWarning raised when importing mimetools in
Brett Cannon721b1452008-08-16 22:00:27 +00002383 BaseHTTPServer, cgi (and rfc822), httplib.
Brett Cannonabe423e2008-08-16 21:47:07 +00002384
Facundo Batistaeb90b782008-08-16 14:44:07 +00002385- Issue #2776: fixed small issue when handling an URL with double slash
2386 after a 302 response in the case of not going through a proxy.
2387
Antoine Pitroub90a8be2008-08-15 21:03:21 +00002388- Issue #2676: in the email package, content-type parsing was hanging on
2389 pathological input because of quadratic or exponential behaviour of a
2390 regular expression.
2391
Antoine Pitrou11ec65d2008-08-14 21:04:30 +00002392- Issue #3476: binary buffered reading through the new "io" library is now
2393 thread-safe.
2394
Brett Cannonbf3157b2008-08-14 05:00:03 +00002395- Silence the DeprecationWarning of rfc822 when it is imported by mimetools
2396 since mimetools itself is deprecated. Because modules are cached, all
2397 subsequent imports of rfc822 will not raise a visible DeprecationWarning.
2398
Antoine Pitrou9fcd4b32008-08-11 17:21:36 +00002399- Issue #3134: shutil referenced undefined WindowsError symbol.
2400
Robert Schuppenies14646332008-08-10 11:01:53 +00002401- Issue #1342811: Fix leak in Tkinter.Menu.delete. Commands associated to
2402 menu entries were not deleted.
2403
Brett Cannon83e81842008-08-09 23:30:55 +00002404- Copied the implementation of reduce() to _functools.reduce() to have a
2405 version that did not raise a DeprecationWarning under -3.
2406
Antoine Pitrou76b8bee2008-08-09 17:27:23 +00002407- Issue #3205: When iterating over a BZ2File fails allocating memory, raise
2408 a MemoryError rather than silently stop the iteration.
2409
Guido van Rossum59ce9012008-08-09 14:55:34 +00002410- Issue #3487: sre "bytecode" validator. Passing invalid "re-bytecode"
2411 to _sre.compile() will now be rejected. This should not affect anybody
2412 since the re.compile() function never generates invalid re-bytecode.
2413
Skip Montanaroa032bf42008-08-08 22:52:51 +00002414- Issue #3436: Make csv.DictReader's fieldnames attribute a property so that
2415 upon first access it can be automatically initialized from the csv file if
2416 it wasn't initialized during instantiation.
2417
Brett Cannon3aa2a492008-08-06 22:28:09 +00002418- Issue #2338: Create imp.reload() to help with transitioning to Python 3.0 as
2419 the reload() built-in has been removed.
2420
Brett Cannon7e30b672008-08-04 21:52:25 +00002421- Changed code in the following modules/packages to remove warnings raised
Brett Cannonc1b76e42008-08-09 23:06:16 +00002422 while running under the ``-3`` flag: aifc, asynchat, asyncore, bdb, bsddb,

2426 subprocess, sqlite3, tarfile, Tkinter, test.test_support, textwrap,
2427 threading, tokenize, traceback, urlparse, wsgiref, xml, xmlrpclib.

Lars Gustäbel727bd0b2008-08-02 11:26:39 +00002429- Issue #3039: Fix tarfile.TarFileCompat.writestr() which always
2430 raised an AttributeError.
2431
Benjamin Peterson01a24322008-07-28 23:35:27 +00002432- Issue #2523: Fix quadratic behaviour when read()ing a binary file without
Antoine Pitroude781a42008-08-09 12:43:23 +00002433 asking for a specific length. This problem only affected files opened
2434 using the new "io" module, not the built-in open() function.
Benjamin Peterson01a24322008-07-28 23:35:27 +00002435
Mark Dickinsonfe84cce2008-07-27 06:39:07 +00002436- Issue #3449: Update decimal module to use most recent specification
2437 (v. 1.68) and tests (v. 2.58) from IBM.
2438
Skip Montanarof9ac43f2008-07-27 00:50:41 +00002439- Issue 3437: Bug fix in robotparser parsing of Allow: lines.

2447
2448- Issue #3303: Fix a crash in locale.strcoll() when calling it with
2449 invalid arguments.
2450
2451- Issue #3302: Fix several crashes when calling locale's gettext functions
2452 with None arguments.
2453
2454- Issue #3389: Allow resolving dotted names for handlers in logging
2455 configuration files.
2456
2457- Deprecate the sunaudio module for removal in Python 3.0.
2458
Antoine Pitrou5fdfa3e2008-07-25 19:42:26 +00002459- Issue #3394: zipfile.writestr sets external attributes when passed a
2460 file name rather than a ZipInfo instance, so files are extracted with
2461 mode 0600 rather than 000 under Unix.
2462
Gregory P. Smitha36f8fe2008-08-04 00:13:29 +00002463- Issue #1857: subprocess.Popen.poll gained an additional _deadstate keyword
2464 argument in python 2.5, this broke code that subclassed Popen to include its
2465 own poll method. Fixed my moving _deadstate to an _internal_poll method.

Nick Coghlan6e8fef02008-08-18 13:14:22 +00002475- Issue #2235: the C API function PyObject_HashNotImplemented and its
2476 interaction with the tp_hash slot (added in 2.6b2) are now documented
2477
Nick Coghlan2a0c2b12008-08-04 12:47:17 +00002478- Issue #643841: The language reference now provides more detailed
2479 coverage of the lookup process for special methods. The disclaimers
2480 regarding lack of coverage of new-style classes have also been
2481 removed, since the coverage is now fairly reasonable.

2490-----------------
2491
Georg Brandl3e483f62008-07-16 22:57:41 +00002492- Issue #3156: Fix inconsistent behavior of the bytearray type: all
2493 its methods now allow for items objects that can be converted to
2494 an integer using operator.index().
2495
Mark Dickinson64b7e502008-07-16 09:40:03 +00002496- Issue #3360: Fix incorrect parsing of '020000000000.0', which
2497 produced a ValueError instead of giving the correct float.
2498
Eric Smitha5fa5a22008-07-16 00:11:49 +00002499- Issue #3083: Add alternate (#) formatting for bin, oct, hex output
2500 for str.format(). This adds the prefix 0b, 0o, or 0x, respectively.
2501
Mark Dickinson7103aa42008-07-15 19:08:33 +00002502- Issue #3008: the float type has a new instance method 'float.hex'
2503 and a new class method 'float.fromhex' to convert floating-point
2504 numbers to and from hexadecimal strings, respectively.
2505
Nick Coghlan6d6bd442008-07-15 15:40:22 +00002506- Issue #2235: __hash__ is once again inherited by default. To allow
2507 collections.Hashable to remain meaningful in the presence of the
2508 default hash implementation (object.__hash__), it is now possible
2509 to explicit block inheritance of hash by setting __hash__=None at
2510 the Python level, or tp_hash=PyObject_HashNotImplemented at the C
2511 level.
2512
Nick Coghlanb028f502008-07-13 14:52:36 +00002513- Issue #3221: Issue a RuntimeWarning instead of raising SystemError if
2514 the parent module cannot be found while performing an absolute import.
2515 This means that an incorrectly defined __package__ attribute will
2516 now only prevent relative imports in that module rather than causing
2517 all imports from that module to fail.
2518
Nick Coghlan14ff9942008-07-08 14:21:42 +00002519- Issue #2517: Allow unicode messages in Exceptions again by correctly
2520 bypassing the instance dictionary when looking up __unicode__ on
2521 new-style classes.
2522
Amaury Forgeot d'Arcbdd941f2008-07-01 20:38:04 +00002523- Issue #3242: Fix a crash inside the print statement, if sys.stdout is
2524 set to a custom object whose write() method happens to install
2525 another file in sys.stdout.

2529 another thread's dictionary.
2530
Mark Dickinson1ec2fcd2008-06-20 14:53:43 +00002531- Issue #3004: Minor change to slice.indices(): the start and stop
2532 arguments are now treated identically, making the behaviour easier
2533 to describe and understand. For example, slice(None, -10,
2534 1).indices(9) now returns (0, 0, 1) instead of (0, -1, 1), and
2535 slice(None, 10, -1).indices(10) returns (9, 9, -1) instead of (9,
2536 10, -1).
2537
Georg Brandl278fc502008-07-19 12:46:12 +00002538- Issue #3219: Calling a function with repeated keyword arguments,
2539 f(a=2, a=23), would not cause a syntax error. This was a regression
2540 from 2.4 caused by the switch to the new compiler.

Georg Brandl5cc774e2008-06-11 20:28:06 +00002990 PPC64 and x86_64 support in one binary).
Ronald Oussoren5640ce22008-06-05 12:58:24 +00002991
2992 This is controlled by the configure argument ``--with-universal-archs``:
2993
2994 - ``--with-universal-archs=all``: install 4-way universal
2995
2996 - ``--with-universal-archs=32-bit``: install 2-way universal, 32-bit (the default)
2997
2998 - ``--with-universal-archs=64-bit``: install 2-way universal, 64-bit

Georg Brandl3ee81df2008-05-17 18:14:43 +00003052- Issue #1631171: Re-implement the 'warnings' module in C (the
3053 original Python code has been kept as backup). This will allow for
3054 using the 'warning's machinery in such places as the parser where
3055 use of pure Python code is not possible. Both the ``showarning()``
3056 and ``formatwarning()`` gain an optional 'line' argument which is
3057 not called by default for backwards-compatibility reasons. Setting
3058 ``warnings.showwarning()`` to an implementation that lacks support
3059 for the ``line`` argument will raise a DeprecationWarning.

3083
Gregory P. Smithd59fefb2008-04-22 08:11:33 +00003084- The getpass module has been improved on Unix. It now uses /dev/tty
3085 by default and uses stderr instead of stdout. A GetPassWarning is
3086 issued when input echo cannot be controlled.

Georg Brandl3ee81df2008-05-17 18:14:43 +00003101- Issue #2513: distutils on Windows is now capable of cross-compiling
Mark Hammond495cf992008-04-07 01:53:39 +00003102 extension modules between 32 and 64 bit platforms. See the distutls

Georg Brandl3ee81df2008-05-17 18:14:43 +00003114- Issue #2385: distutils.core.run_script() makes __file__ available,
3115 so the controlled environment will more closely mirror the typical
3116 script environment. This supports setup.py scripts that refer to
3117 data files.

Georg Brandl3ee81df2008-05-17 18:14:43 +00003122- Issue #2550: The approach used by client/server code for obtaining
3123 ports to listen on in network-oriented tests has been refined in an
3124 effort to facilitate running multiple instances of the entire
3125 regression test suite in parallel without issue.
3126 test_support.bind_port() has been fixed such that it will always
3127 return a unique port -- which wasn't always the case with the
3128 previous implementation, especially if socket options had been set
3129 that affected address reuse (i.e. SO_REUSEADDR, SO_REUSEPORT). The
3130 new implementation of bind_port() will actually raise an exception
3131 if it is passed an AF_INET/SOCK_STREAM socket with either the
3132 SO_REUSEADDR or SO_REUSEPORT socket option set. Furthermore, if
3133 available, bind_port() will set the SO_EXCLUSIVEADDRUSE option on
3134 the socket it's been passed. This currently only applies to
3135 Windows. This option prevents any other sockets from binding to the
3136 host/port we've bound to, thus removing the possibility of the
3137 'non-deterministic' behaviour, as Microsoft puts it, that occurs
3138 when a second SOCK_STREAM socket binds and accepts to a host/port
3139 that's already been bound by another socket. The optional preferred
3140 port parameter to bind_port() has been removed. Under no
3141 circumstances should tests be hard coding ports!
3142
3143 test_support.find_unused_port() has also been introduced, which will
3144 pass a temporary socket object to bind_port() in order to obtain an
3145 unused port. The temporary socket object is then closed and
3146 deleted, and the port is returned. This method should only be used
3147 for obtaining an unused port in order to pass to an external program
3148 (i.e. the -accept [port] argument to openssl's s_server mode) or as
3149 a parameter to a server-oriented class that doesn't give you direct
3150 access to the underlying socket used.
3151
3152 Finally, test_support.HOST has been introduced, which should be used
3153 for the host argument of any relevant socket calls (i.e. bind and
3154 connect).
Trent Nelsone41b0062008-04-08 23:47:30 +00003155
3156 The following tests were updated to following the new conventions:
Georg Brandl3ee81df2008-05-17 18:14:43 +00003157 test_socket, test_smtplib, test_asyncore, test_ssl, test_httplib,
Trent Nelsone41b0062008-04-08 23:47:30 +00003158 test_poplib, test_ftplib, test_telnetlib, test_socketserver,
3159 test_asynchat and test_socket_ssl.
3160
Georg Brandl3ee81df2008-05-17 18:14:43 +00003161 It is now possible for multiple instances of the regression test
3162 suite to run in parallel without issue.

3429-----------------
3430
Fred Drakea8ee94b2008-03-01 02:45:07 +00003431- Issue #2051: pyc and pyo files are no longer created with permission
Barry Warsaw52973612008-03-01 02:23:38 +00003432 644. The mode is now inherited from the py file.
Christian Heimes40346852008-02-23 17:52:07 +00003433
Georg Brandlad61bc82008-02-23 15:11:18 +00003434- Issue #2067: file.__exit__() now calls subclasses' close() method.
3435
3436- Patch #1759: Backport of PEP 3129 class decorators.
Christian Heimes5224d282008-02-23 15:01:05 +00003437
Vinay Sajipb7edfc42008-04-02 21:10:23 +00003438- Issue #1881: An internal parser limit has been increased. Also see
Facundo Batistafc2d0102008-02-23 12:01:13 +00003439 issue 215555 for a discussion.
3440
Eric Smitha73fbe72008-02-23 03:09:44 +00003441- Added the future_builtins module, which contains hex() and oct().
3442 These are the PEP 3127 version of these functions, designed to be
3443 compatible with the hex() and oct() builtins from Python 3.0. They
3444 differ slightly in their output formats from the existing, unchanged
3445 Python 2.6 builtins. The expected usage of the future_builtins
3446 module is:
3447 from future_builtins import hex, oct
3448
Eric Smith7ef40bf2008-02-20 23:34:22 +00003449- Issue #1600: Modifed PyOS_ascii_formatd to use at most 2 digit
3450 exponents for exponents with absolute value < 100. Follows C99
3451 standard. This is a change on Windows, which would use 3 digits.
3452 Also, added 'n' to the formats that PyOS_ascii_formatd understands,
3453 so that any alterations it does to the resulting string will be
3454 available in stringlib/formatter.h (for float.__format__).
3455
Eric Smith5a3c1352008-02-19 13:21:56 +00003456- Implemented PEP 3101, Advanced String Formatting. This adds a new
3457 builtin format(); a format() method for str and unicode; a
3458 __format__() method to object, str, unicode, int, long, float, and
3459 datetime; the class string.Formatter; and the C API
3460 PyObject_Format().
3461
Georg Brandl3ee81df2008-05-17 18:14:43 +00003462- Fixed several potential crashes, all caused by specially crafted
3463 __del__ methods exploiting objects in temporarily inconsistent
3464 state.
Amaury Forgeot d'Arc632fad32008-02-16 20:55:24 +00003465
Vinay Sajipb7edfc42008-04-02 21:10:23 +00003466- Issue #2115: Important speedup in setting __slot__ attributes. Also
Georg Brandl3ee81df2008-05-17 18:14:43 +00003467 prevent a possible crash: an Abstract Base Class would try to access
3468 a slot on a registered virtual subclass.
Amaury Forgeot d'Arc60d6c7f2008-02-15 21:22:45 +00003469
Georg Brandl3ee81df2008-05-17 18:14:43 +00003470- Fixed repr() and str() of complex numbers with infinity or nan as
3471 real or imaginary part.
Christian Heimes2f0da532008-02-15 06:57:08 +00003472
Georg Brandl3ee81df2008-05-17 18:14:43 +00003473- Clear all free lists during a gc.collect() of the highest generation
3474 in order to allow pymalloc to free more arenas. Python may give back
3475 memory to the OS earlier.
Christian Heimes3b718a72008-02-14 12:47:33 +00003476
Georg Brandl3ee81df2008-05-17 18:14:43 +00003477- Issue #2045: Fix an infinite recursion triggered when printing a
3478 subclass of collections.defaultdict, if its default_factory is set
3479 to a bound method.
Amaury Forgeot d'Arcb01aa432008-02-08 00:56:02 +00003480
Christian Heimesf75dbef2008-02-08 00:11:31 +00003481- Fixed a minor memory leak in dictobject.c. The content of the free
3482 list was not freed on interpreter shutdown.
3483
Georg Brandl3ee81df2008-05-17 18:14:43 +00003484- Limit free list of method and builtin function objects to 256
3485 entries each.
Christian Heimes6075a822008-02-06 12:44:34 +00003486
Georg Brandl3ee81df2008-05-17 18:14:43 +00003487- Patch #1953: Added ``sys._compact_freelists()`` and the C API
3488 functions ``PyInt_CompactFreeList`` and ``PyFloat_CompactFreeList``
Christian Heimes422051a2008-02-04 18:00:12 +00003489 to compact the internal free lists of pre-allocted ints and floats.
3490
Georg Brandl3ee81df2008-05-17 18:14:43 +00003491- Issue #1983: Fixed return type of fork(), fork1() and forkpty()
3492 calls. Python expected the return type int but the fork familie
3493 returns pi_t.
Christian Heimes951cc0f2008-01-31 23:08:23 +00003494
Georg Brandl3ee81df2008-05-17 18:14:43 +00003495- Issue #1678380: Fix a bug that identifies 0j and -0j when they
3496 appear in the same code unit.
Mark Dickinson105be772008-01-31 22:17:37 +00003497

3505 the internal lookup cache for ref leak tests.
Christian Heimes908caac2008-01-27 23:34:59 +00003506
Georg Brandl3ee81df2008-05-17 18:14:43 +00003507- Patch #1473257: generator objects gain a gi_code attribute. This is
3508 the same object as the func_code attribute of the function that
3509 produced the generator.
Georg Brandl0cdf9a32008-01-26 14:14:20 +00003510
Georg Brandl3ee81df2008-05-17 18:14:43 +00003511- Issue #1920: "while 0" statements were completely removed by the
3512 compiler, even in the presence of an "else" clause, which is
3513 supposed to be run when the condition is false. Now the compiler
3514 correctly emits bytecode for the "else" suite.
Amaury Forgeot d'Arc31eaafe2008-01-24 22:59:25 +00003515
Guido van Rossumeead05f2008-01-24 18:21:02 +00003516- A few crashers fixed: weakref_in_del.py (issue #1377858);
3517 loosing_dict_ref.py (issue #1303614, test67.py);
3518 borrowed_ref_[34].py (not in tracker).
3519
Vinay Sajipd7cf32e2008-01-24 12:43:33 +00003520- Issue #1069410: The "can't load dll" message box on Windows is
Christian Heimesb2302ba2008-01-23 17:15:06 +00003521 suppressed while an extension is loaded by calling SetErrorMode in
3522 dynload_win.c. The error is still reported properly.
3523
Georg Brandl3ee81df2008-05-17 18:14:43 +00003524- Issue #1915: Python compiles with --enable-unicode=no again. However
Christian Heimes082c9b02008-01-23 14:20:50 +00003525 several extension methods and modules do not work without unicode
3526 support.
3527
Georg Brandl26543b12008-01-21 18:36:51 +00003528- Issue #1882: when compiling code from a string, encoding cookies in the
3529 second line of code were not always recognized correctly.
3530
Georg Brandl14404b62008-01-19 19:27:05 +00003531- Issue #1679: "0x" was taken as a valid integer literal.
3532
Georg Brandl6caad7d2008-01-26 14:19:22 +00003533- Issue #1865: ``bytes`` as an alias for ``str`` and b"" as an alias "" were
Christian Heimes288e89a2008-01-18 18:24:07 +00003534 added.
3535
Christian Heimesc94e2b52008-01-14 04:13:37 +00003536- sys.float_info / PyFloat_GetInfo: The floating point information
3537 object was converted from a dict to a specialized structseq object.
3538
Georg Brandl3ee81df2008-05-17 18:14:43 +00003539- Patch #1816: Added sys.flags structseq. It exposes the status of
3540 most command line arguments and PYTHON* environment variables.
Christian Heimesf31b69f2008-01-14 03:42:48 +00003541
Georg Brandl3ee81df2008-05-17 18:14:43 +00003542- Objects/structseq.c: Implemented new structseq representation. The
3543 patch makes structseqs (e.g. the return value of os.stat) more
3544 readable.
Christian Heimes9c201962008-01-14 03:33:52 +00003545
Georg Brandl3ee81df2008-05-17 18:14:43 +00003546- Patch #1700288: added a type attribute cache that caches method

Georg Brandl3ee81df2008-05-17 18:14:43 +00003568 and INF. float("nan"), float("inf") and float("-inf") now work on
3569 every platform with IEEE 754 semantics.
Christian Heimes0a8143f2007-12-18 23:22:54 +00003570
Georg Brandl3ee81df2008-05-17 18:14:43 +00003571- Compiler now generates simpler and faster code for dictionary
3572 literals. The oparg for BUILD_MAP now indicates an estimated
3573 dictionary size. There is a new opcode, STORE_MAP, for adding
3574 entries to the dictionary.

3619 smaller than LONG_MAX. Formerly, it raised an OverflowError. Now,
3620 automatically shifts from ints to longs.
Raymond Hettinger8f669372007-10-03 21:18:11 +00003621
Georg Brandl3ee81df2008-05-17 18:14:43 +00003622- Issue #1686386: Tuple's tp_repr did not take into account the
3623 possibility of having a self-referential tuple, which is possible
3624 from C code. Nor did object's tp_str consider that a type's tp_str
3625 could do something that could lead to an inifinite recursion.
3626 Py_ReprEnter() and Py_EnterRecursiveCall(), respectively, fixed the
3627 issues.
Brett Cannon0b14f242007-09-30 19:45:10 +00003628
Georg Brandl3ee81df2008-05-17 18:14:43 +00003629- Issue #1164: It was possible to trigger deadlock when using the
3630 'print' statement to write to a file since the GIL was not released
3631 as needed. Now PyObject_Print() does the right thing along with
3632 various tp_print implementations of the built-in types and those in
3633 the collections module.
Brett Cannon01531592007-09-17 03:28:34 +00003634
Georg Brandl3ee81df2008-05-17 18:14:43 +00003635- Issue #1147: Exceptions were directly allowing string exceptions in
3636 their throw() method even though string exceptions no longer
3637 allowed.
Brett Cannon4c20bc42007-09-11 21:02:28 +00003638
Georg Brandl3ee81df2008-05-17 18:14:43 +00003639- Issue #1096: Prevent a segfault from getting the repr of a very
3640 deeply nested list by using the recursion counter.
Brett Cannona0c05512007-09-10 21:38:27 +00003641
Brett Cannon1e534b52007-09-07 04:18:30 +00003642- Issue #1202533: Fix infinite recursion calls triggered by calls to
Georg Brandl3ee81df2008-05-17 18:14:43 +00003643 PyObject_Call() never calling back out to Python code to trigger
3644 recursion depth updates/checks. Required the creation of a static
3645 RuntimeError instance in case normalizing an exception put the
3646 recursion check value past its limit. Fixes crashers
3647 infinite_rec_(1|2|4|5).py.
Brett Cannon1e534b52007-09-07 04:18:30 +00003648

3653 with %G.
3654
Georg Brandl3ee81df2008-05-17 18:14:43 +00003655- Prevent expandtabs() on string and unicode objects from causing a

Neal Norwitz0ac60192007-05-27 04:08:54 +00003662- Add new attribute names for function objects. All the func_* become
Georg Brandl3ee81df2008-05-17 18:14:43 +00003663 __*__ attributes. (Some already existed, e.g., __doc__ and
3664 __name__.)
Neal Norwitz0ac60192007-05-27 04:08:54 +00003665
Neal Norwitz8b2bfbc2007-05-23 06:35:32 +00003666- Add -3 option to the interpreter to warn about features that are
3667 deprecated and will be changed/removed in Python 3.0.
3668
Georg Brandl2134e752007-05-21 20:34:16 +00003669- Patch #1686487: you can now pass any mapping after '**' in function
3670 calls.
3671
Collin Winter62903052007-05-18 23:11:24 +00003672- except clauses may now be spelled either "except E, target:" or
Georg Brandl3ee81df2008-05-17 18:14:43 +00003673 "except E as target:". This is to provide forwards compatibility
3674 with Python 3.0.
Collin Winter62903052007-05-18 23:11:24 +00003675
Brett Cannon229cee22007-05-05 01:34:02 +00003676- Deprecate BaseException.message as per PEP 352.
3677
Georg Brandl3ee81df2008-05-17 18:14:43 +00003678- Issue #1303614: don't expose object's __dict__ when the dict is
Armin Rigo9790a272007-05-02 19:23:31 +00003679 inherited from a builtin base.
3680
Vinay Sajip8549ce32007-05-06 17:53:37 +00003681- When __slots__ are set to a unicode string, make it work the same as
Neal Norwitzcbd9ee62007-04-14 05:25:50 +00003682 setting a plain string, ie don't expand to single letter identifiers.
3683
Raymond Hettinger13936692007-04-11 18:40:58 +00003684- Request #1191699: Slices can now be pickled.
3685
Raymond Hettinger4db5fe92007-04-12 04:10:00 +00003686- Request #1193128: str.translate() now allows a None argument for
3687 translations that only remove characters without re-mapping the
3688 remaining characters.
3689
Georg Brandl5cb76c12007-03-21 09:00:39 +00003690- Patch #1682205: a TypeError while unpacking an iterable is no longer
3691 masked by a generic one with the message "unpack non-sequence".
3692
Neal Norwitzaa754b72007-03-21 06:39:48 +00003693- Remove unused file Python/fmod.c.
3694
Guido van Rossum143b5642007-03-23 04:58:42 +00003695- Bug #1683368: The object.__init__() and object.__new__() methods are
3696 now stricter in rejecting excess arguments. The only time when
3697 either allows excess arguments is when it is not overridden and the
3698 other one is. For backwards compatibility, when both are
3699 overridden, it is a deprecation warning (for now; maybe a Py3k
Guido van Rossum234b1ff2007-03-23 19:39:01 +00003700 warning later). Also, type.__init__() insists on the same signature
3701 as supported by type.__new__().
Guido van Rossum143b5642007-03-23 04:58:42 +00003702
Georg Brandl3ee81df2008-05-17 18:14:43 +00003703- Patch #1675423: PyComplex_AsCComplex() now tries to convert an
3704 object to complex using its __complex__() method before falling back
3705 to the __float__() method. Therefore, the functions in the cmath
3706 module now can operate on objects that define a __complex__()
3707 method.
Georg Brandl2b869942007-03-17 16:08:45 +00003708
Georg Brandl3ee81df2008-05-17 18:14:43 +00003709- Patch #1623563: allow __class__ assignment for classes with
3710 __slots__. The old and the new class are still required to have the
3711 same slot names.

3718 its type.
Žiga Seilnacht20f43d32007-03-15 11:44:55 +00003719
Georg Brandl3ee81df2008-05-17 18:14:43 +00003720- Patch #1680015: Don't modify __slots__ tuple if it contains an

3724
Georg Brandl7b9c5552007-03-12 14:30:05 +00003725- Bug #1678647: write a newline after printing an exception in any
3726 case, even when converting the value to a string failed.
3727
Georg Brandl871f1bc2007-03-12 13:17:36 +00003728- The dir() function has been extended to call the __dir__() method on
Georg Brandl3ee81df2008-05-17 18:14:43 +00003729 its argument, if it exists. If not, it will work like before. This
3730 allows customizing the output of dir() in the presence of a
3731 __getattr__().

3740 parthensized forms. This means complex(repr(x)) now works instead of
3741 raising a ValueError.
Collin Wintere38051d2007-03-09 20:33:07 +00003742
Georg Brandlaa2321b2007-03-07 00:40:28 +00003743- Patch #703779: unset __file__ in __main__ after running a file. This
Georg Brandl3ee81df2008-05-17 18:14:43 +00003744 makes the filenames the warning module prints much more sensible
3745 when a PYTHONSTARTUP file is used.
Georg Brandlaa2321b2007-03-07 00:40:28 +00003746

Georg Brandl0fca97a2007-03-05 22:28:08 +00003758- Patch #1674228: when assigning a slice (old-style), check for the
3759 sq_ass_slice instead of the sq_slice slot.
3760
Georg Brandl3ee81df2008-05-17 18:14:43 +00003761- When printing an unraisable error, don't print exceptions. before
3762 the name. This duplicates the behavior whening normally printing
3763 exceptions.

4392 exception.

Georg Brandl3ee81df2008-05-17 18:14:43 +00004673- Issue #829951: In the smtplib module, SMTP.starttls() now complies
4674 with RFC 3207 and forgets any knowledge obtained from the server not
4675 obtained from the TLS negotiation itself. Patch contributed by Bill
4676 Fenner.
Gregory P. Smith2b3ba582008-01-17 08:03:17 +00004677
Georg Brandl3ee81df2008-05-17 18:14:43 +00004678- Issue #1339: The smtplib.SMTP class has been refactored a bit such
Gregory P. Smithbde4ae42008-01-17 08:35:49 +00004679 that the SMTP.starttls() caller no longer needs to call ehlo()
4680 beforehand. SMTP.starttls() now raises an exception of the server
Georg Brandl3ee81df2008-05-17 18:14:43 +00004681 does not claim to support starttls. Adds the
4682 SMTP.ehlo_or_helo_if_needed() method. Patch contributed by Bill

4763 complex, tuple, list, dict, set, and frozenset. Formerly, it would
4764 silently miscode subclasses of those types. Now, it raises a

Georg Brandl3ee81df2008-05-17 18:14:43 +00004781 time so that opening a database previously created with the DB_DUP
4782 or DB_DUPSORT flag set will keep the proper behavior on subsequent
4783 opens. Specifically: dictionary assignment to a DB object will
4784 replace all values for a given key when the database allows
4785 duplicate values. DB users should use DB.put(k, v) when they want
4786 to store duplicates; not DB[k] = v.
Gregory P. Smithec10a4a2007-11-05 02:32:26 +00004787

4793 characters with ASCII value less than 32. Also, it correctly quotes
4794 dots only if they occur on a single line, as opposed to the previous
4795 behavior of quoting dots if they are the second character of any
4796 line.
Georg Brandl4aef7272007-03-13 22:49:43 +00004797

5119-----
5120
Georg Brandl3ee81df2008-05-17 18:14:43 +00005121- Unified naming convention for free lists and their limits. All free
5122 lists in Object/ are named ``free_list``, the counter ``numfree``
5123 and the upper limit is a macro ``PyName_MAXFREELIST`` inside an
5124 #ifndef block.
Christian Heimes5b970ad2008-02-06 13:33:44 +00005125
Georg Brandl3ee81df2008-05-17 18:14:43 +00005126- ``PySet_Add()`` can now modify a newly created frozenset. Similarly
5127 to ``PyTuple_SetItem``, it can be used to populate a brand new
5128 frozenset; but it does not steal a reference to the added item.

5136- Patch #1720595: add T_BOOL to the range of structmember types.
5137
5138- Issue #1534: Added ``PyFloat_GetMax()``, ``PyFloat_GetMin()`` and
5139 ``PyFloat_GetInfo()`` to the float API.
5140
Georg Brandl3ee81df2008-05-17 18:14:43 +00005141- Issue #1521: On 64bit platforms, using PyArgs_ParseTuple with the t#
5142 of w# format code incorrectly truncated the length to an int, even
5143 when PY_SSIZE_T_CLEAN is set. The str.decode method used to return
5144 incorrect results with huge strings.
Georg Brandl6caad7d2008-01-26 14:19:22 +00005145
Georg Brandl3ee81df2008-05-17 18:14:43 +00005146- Issue #1629: Renamed Py_Size, Py_Type and Py_Refcnt to Py_SIZE,
5147 Py_TYPE and Py_REFCNT.

5164- Fix some leftovers from the conversion from int to Py_ssize_t
5165 (relevant to strings and sequences of more than 2**31 items).
5166
5167- Make _PyGILState_NoteThreadState() static, it was not used anywhere
5168 outside of pystate.c and should not be necessary.
5169
Georg Brandl3ee81df2008-05-17 18:14:43 +00005170- ``PyImport_Import`` and ``PyImport_ImportModule`` now always do
5171 absolute imports. In earlier versions they might have used relative
5172 imports under some conditions.
Christian Heimes000a0742008-01-03 22:16:32 +00005173
Georg Brandl3ee81df2008-05-17 18:14:43 +00005174- Added case insensitive comparison methods ``PyOS_stricmp(char*,
5175 char*)`` and ``PyOS_strnicmp(char*, char*, Py_ssize_t)``.
Christian Heimes000a0742008-01-03 22:16:32 +00005176
Georg Brandl3ee81df2008-05-17 18:14:43 +00005177- Bug #1542693: remove semi-colon at end of PyImport_ImportModuleEx

Georg Brandl3ee81df2008-05-17 18:14:43 +00005184- Patch #1706: Drop support for Win9x, WinME and NT4. Python now
5185 requires Windows 2000 or greater. The _WINVER and NTDDI_VERSION
5186 macros are set to Win2k for x86/32bit builds and WinXP for AMD64
5187 builds.
Christian Heimes95d64472008-02-09 19:55:22 +00005188

Georg Brandl3ee81df2008-05-17 18:14:43 +00005202- Removed the macfs module. It had been deprecated since Python 2.5.
5203 This lead to the deprecation of macostools.touched() as it relied
5204 solely on macfs and was a no-op under OS X.
