48Core and Builtins
49-----------------
50
Benjamin Petersonecdae192010-01-04 00:43:01 +000051- The __complex__ method is now looked up on the class of instances to make it
52 consistent with other special methods.
53
Antoine Pitrou5b7139a2010-01-02 21:12:58 +000054- Issue #7462: Implement the stringlib fast search algorithm for the `rfind`,
55 `rindex`, `rsplit` and `rpartition` methods. Patch by Florent Xicluna.
56
Mark Dickinson1b34d252010-01-01 17:27:30 +000057- Issue #5080: A number of functions and methods previously produced a
58 DeprecationWarning when passed a float argument where an integer was
59 expected. These functions and methods now raise TypeError instead.
60 The majority of the effects of this change are in the extension
61 modules, but some core functions and methods are affected: notably
62 the 'chr', 'range' and 'xrange' builtins, and many unicode/str
63 methods.
64
Benjamin Peterson0f02d392009-12-30 19:34:10 +000065- Issue #7604: Deleting an unset slotted attribute did not raise an
66 AttributeError.
67
Mark Dickinson99d652e2009-12-30 12:12:23 +000068- Issue #7534: Fix handling of IEEE specials (infinities, nans,
69 negative zero) in ** operator. The behaviour now conforms to that
70 described in C99 Annex F.
71
Amaury Forgeot d'Arcc8a2ce72009-12-29 23:06:17 +000072- Issue #7579: the msvcrt module now has docstrings for all its functions.
73
Amaury Forgeot d'Arc8645a5c2009-12-29 22:03:38 +000074- Issue #7413: Passing '\0' as the separator to datetime.datetime.isoformat()
75 used to drop the time part of the result.
76
Mark Dickinson46572832009-12-27 14:55:57 +000077- Issue #1811: improve accuracy and cross-platform consistency for
78 true division of integers: the result of a/b is now correctly
79 rounded for ints a and b (at least on IEEE 754 platforms), and in
80 particular does not depend on the internal representation of a long.
81
Ezio Melottif84caf42009-12-24 22:25:17 +000082- Issue #6108: unicode(exception) and str(exception) should return the same
83 message when only __str__ (and not __unicode__) is overridden in the subclass.
84
Ronald Oussoren92919a62009-12-24 13:30:58 +000085- Issue #6834: replace the implementation for the 'python' and 'pythonw'
86 executables on OSX.
87
88 These executables now work properly with the arch(1) command:
89 ``arch -ppc python`` will start a universal binary version of python
90 in PPC mode (unlike previous releases).
91
R. David Murray0a0a1a82009-12-14 16:28:26 +000092- Issue #1680159: unicode coercion during an 'in' operation no longer masks
93 the underlying error when the coercion fails for the left hand operand.
94
Benjamin Peterson4895af42009-12-13 16:36:53 +000095- Issue #7491: Metaclass's __cmp__ method was ignored.
96
Antoine Pitrou2a08b422009-12-13 16:18:14 +000097- Issue #7466: segmentation fault when the garbage collector is called
Antoine Pitrou54584182010-01-07 17:54:10 +000098 in the middle of populating a tuple. Patch by Florent Xicluna.

106 by Arfrever.
107
Antoine Pitrou80157252010-01-08 19:20:17 +0000108- Issue #7092: Remove py3k warning when importing cPickle. 2to3 handles
109 renaming of `cPickle` to `pickle`. The warning was annoying since there's
110 no alternative to cPickle if you care about performance. Patch by Florent
111 Xicluna.
112
Antoine Pitrou0d423b82010-01-07 17:46:49 +0000113- Issue #7455: Fix possible crash in cPickle on invalid input. Patch by

120 and make it implement the `io.BufferedIOBase` ABC to allow for further
121 speedups by wrapping it in an `io.BufferedReader`. Patch by Nir Aides.
122
123- Issue #3972: httplib.HTTPConnection now accepts an optional source_address
Gregory P. Smith9d325212010-01-03 02:06:07 +0000124 parameter to allow specifying where your connections come from.

Senthil Kumaran7713acf2009-12-20 06:05:13 +0000142 Patch by Tatsuhiro Tsujikawa.
143
Benjamin Petersonddd392c2009-12-13 19:19:07 +0000144- Issue #7349: Make methods of file objects in the io module accept None as an
145 argument where file-like objects (ie StringIO and BytesIO) accept them to mean
146 the same as passing no argument.
147
Benjamin Petersonc4771d22009-12-13 17:31:31 +0000148- Issue #7348: StringIO.StringIO.readline(-1) now acts as if it got no argument
149 like other file objects.
150

217-----------------
218
Amaury Forgeot d'Arcd7288712009-12-01 21:51:04 +0000219- Issue #7419: setlocale() could crash the interpreter on Windows when called
220 with invalid values.
221
Eric Smithc4ab8332009-11-29 17:40:57 +0000222- Issue #3382: 'F' formatting for float and complex now convert the
223 result to upper case. This only affects 'inf' and 'nan', since 'f'
224 no longer converts to 'g' for large values.
Amaury Forgeot d'Arcd7288712009-12-01 21:51:04 +0000225
Mark Dickinson9dd5e162009-11-23 20:54:09 +0000226- Remove switch from "%f" formatting to "%g" formatting for floats
227 larger than 1e50 in absolute value.
228
Mark Dickinson18cfada2009-11-23 18:46:41 +0000229- Remove restrictions on precision when formatting floats. E.g.,
230 "%.120g" % 1e-100 used to raise OverflowError, but now gives the
231 requested 120 significant digits instead.
232
Benjamin Peterson89b1a5c2009-11-19 22:58:01 +0000233- Add Py3k warnings for parameter names in parenthesis.
234
Benjamin Peterson48f0a8d2009-11-19 23:19:29 +0000235- Issue #7362: Give a proper error message for def f((x)=3): pass.
Benjamin Peterson89b1a5c2009-11-19 22:58:01 +0000236
Ronald Oussoren315cd0c2009-11-19 16:25:21 +0000237- Issue #7085: Fix crash when importing some extensions in a thread
238 on MacOSX 10.6.
239
Mark Dickinsonb678de82009-11-19 18:41:49 +0000240- Issue #7117: repr(x) for a float x returns a result based on the
241 shortest decimal string that's guaranteed to round back to x under
242 correct rounding (with round-half-to-even rounding mode).
243 Previously it gave a string based on rounding x to 17 decimal digits.
244 repr(x) for a complex number behaves similarly. On platforms where
245 the correctly-rounded strtod and dtoa code is not supported (see below),
246 repr is unchanged.
247
248- Issue #7117: On almost all platforms: float-to-string and
249 string-to-float conversions within Python are now correctly rounded.
250 Places these conversions occur include: str for floats and complex
251 numbers; the float and complex constructors; old-style and new-style
252 numeric formatting; serialization and deserialization of floats and
253 complex numbers using marshal, pickle and json; parsing of float and
254 imaginary literals in Python code; Decimal-to-float conversion.
255
256 The conversions use a Python-adapted version of David Gay's
257 well-known dtoa.c, providing correctly-rounded strtod and dtoa C
258 functions. This code is supported on Windows, and on Unix-like
259 platforms using gcc, icc or suncc as the C compiler. There may be a
260 small number of platforms on which correct operation of this code
261 cannot be guaranteed, so the code is not used: notably, this applies
262 to platforms where the C double format is not IEEE 754 binary64, and
263 to platforms on x86 hardware where the x87 FPU is set to 64-bit
264 precision and Python's configure script is unable to determine how
265 to change the FPU precision. On these platforms conversions use the
266 platform strtod and dtoa, as before.
267
Mark Dickinsonbd15a062009-11-18 19:33:35 +0000268- Issue #7117: Backport round implementation from Python 3.x. round
Mark Dickinsonb678de82009-11-19 18:41:49 +0000269 now uses the correctly-rounded string <-> float conversions
270 described above (when available), and so produces correctly rounded
271 results that will display nicely under the float repr. There are
272 two related small changes: (1) round now accepts any class with an
273 __index__ method for its second argument (but no longer accepts
Mark Dickinsonbd15a062009-11-18 19:33:35 +0000274 floats for the second argument), and (2) an excessively large second
275 integer argument (e.g., round(1.234, 10**100)) no longer raises an
276 exception.
277
Philip Jenveyfab8be22009-11-17 02:42:26 +0000278- Issue #1757126: Fix the cyrillic-asian alias for the ptcp154 encoding.
279
Benjamin Petersone36199b2009-11-12 23:39:44 +0000280- Fix several issues with compile(). The input can now contain Windows and Mac
281 newlines and is no longer required to end in a newline.
282
Mark Dickinsonc04c7c52009-10-26 22:28:14 +0000283- Remove length limitation when constructing a complex number from a
284 unicode string.
285
Raymond Hettingerfa7dadd2009-11-01 20:45:16 +0000286- Issue #7244: itertools.izip_longest() no longer ignores exceptions
287 raised during the formation of an output tuple.
288
Mark Dickinson8d87dc02009-10-25 20:39:06 +0000289- Issue #1087418: Boost performance of bitwise operations for longs.

303
Neil Schemenauer7fdd1cb2009-10-14 17:17:14 +0000304- Issue #1754094: Improve the stack depth calculation in the compiler.
305 There should be no other effect than a small decrease in memory use.
306 Patch by Christopher Tur Lesniewski-Laas.

406
Mark Dickinsona4e0efa2009-05-20 18:43:07 +0000407- Issue #5829: complex("1e500") no longer raises OverflowError. This

421 was locale aware; and (3) the interpretation of fromhex('-nan')
422 didn't match that of float('-nan').
423
Eric Smitha985a3a2009-05-05 18:26:08 +0000424- Issue #5920: For float.__format__, change the behavior with the
425 empty presentation type (that is, not one of 'e', 'f', 'g', or 'n')
426 to be like 'g' but with at least one decimal point and with a
427 default precision of 12. Previously, the behavior the same but with
428 a default precision of 6. This more closely matches str(), and
429 reduces surprises when adding alignment flags to the empty
430 presentation type. This also affects the new complex.__format__ in
431 the same way.
432
R. David Murray7ba8e1c2009-05-04 22:16:24 +0000433- Issue #5890: in subclasses of 'property' the __doc__ attribute was

496 untrackable objects are not tracked by the garbage collector. This can
497 reduce the size of collections and therefore the garbage collection overhead
498 on long-running programs, depending on their particular use of datatypes.
499
Mark Dickinson0b666bf2009-03-23 18:25:13 +0000500- Issue #5512: Rewrite PyLong long division algorithm (x_divrem) to

505 2**15 for the internal representation of integers, for performance
506 reasons. Base 2**30 is enabled by default on 64-bit machines. Add

533 on a 64-bit system.
534
Antoine Pitrou76a4b892009-02-13 13:52:33 +0000535- Issue #5186: Reduce hash collisions for objects with no __hash__ method by

542
Georg Brandl29c6a282009-04-05 20:23:13 +0000543- Issue #1242657: the __len__() and __length_hint__() calls in several tools
Raymond Hettingerb5163702009-02-02 21:50:13 +0000544 were suppressing all exceptions. These include list(), filter(), map(),

Skip Montanarof205c132008-12-23 03:30:15 +0000600- Added test case to ensure attempts to read from a file opened for writing
601 fail.
602
Antoine Pitrou73c0e652008-12-17 22:46:54 +0000603- Issue #2467: gc.DEBUG_STATS reported invalid elapsed times. Also, always

613 context manager returns a value that cannot be converted to a bool.
614
Jeffrey Yasskinffd42cf2008-12-10 07:35:02 +0000615- Issue #4597: Fixed several opcodes that weren't always propagating
616 exceptions.
617
Mark Dickinson826f3fe2008-12-05 21:55:28 +0000618- Issue #4445: Replace "sizeof(PyStringObject)" with
619 "offsetof(PyStringObject, ob_sval) + 1" when allocating memory for
620 str instances. On a typical machine this saves 3 bytes of memory
621 (on average) per string allocation.
622
Amaury Forgeot d'Arcdc619012008-11-22 20:01:18 +0000623- Issue #3996: On Windows, the PyOS_CheckStack function would cause the
624 interpreter to abort ("Fatal Python error: Could not reset the stack!")
625 instead of throwing a MemoryError.
626
Raymond Hettinger7989a4d2008-12-03 15:42:10 +0000627- Issue #3689: The list reversed iterator now supports __length_hint__
628 instead of __len__. Behavior now matches other reversed iterators.
629
Benjamin Petersonc078f922008-11-21 22:27:24 +0000630- Issue #4367: Python would segfault during compiling when the unicodedata
631 module couldn't be imported and \N escapes were present.
632
Vinay Sajip213faca2008-12-03 23:22:58 +0000633- Issue #4233: Changed semantic of ``_fileio.FileIO``'s ``close()``
Amaury Forgeot d'Arc32265652008-11-20 23:34:31 +0000634 method on file objects with closefd=False. The file descriptor is still
635 kept open but the file object behaves like a closed file. The ``FileIO``
636 object also got a new readonly attribute ``closefd``.
637
Benjamin Peterson46cc6d12008-11-19 21:49:09 +0000638- Issue #4348: Some bytearray methods returned that didn't cause any change to
639 the bytearray, returned the same bytearray instead of a copy.
640
Amaury Forgeot d'Arc7cfe7ea2008-11-18 22:19:37 +0000641- Issue #4317: Fixed a crash in the imageop.rgb2rgb8() function.

649
Amaury Forgeot d'Arc69a9c5b2008-10-30 21:18:34 +0000650- Issue #4176: Fixed a crash when pickling an object which ``__reduce__``
651 method does not return iterators for the 4th and 5th items.
652
Benjamin Petersonbdca9422008-10-26 20:21:13 +0000653- Issue #4209: Enabling unicode_literals and the print_function in the same
654 __future__ import didn't work.
655
Benjamin Peterson399b1fe2008-10-25 02:53:28 +0000656- Using ``nonlocal`` as a variable name will now raise a Py3k SyntaxWarning
Georg Brandl7fb00ad2008-10-25 07:00:52 +0000657 because it is a reserved word in 3.x.
Benjamin Peterson399b1fe2008-10-25 02:53:28 +0000658
Hirokazu Yamamoto10a018c2008-10-09 10:00:30 +0000659- On windows, os.chdir given unicode was not working if GetCurrentDirectoryW
660 returned a path longer than MAX_PATH. (But It's doubtful this code path is
661 really executed because I cannot move to such directory on win2k)
662
Amaury Forgeot d'Arcd78b9dc2008-10-07 20:32:10 +0000663- Issue #4069: When set.remove(element) is used with a set element, the element
664 is temporarily replaced with an equivalent frozenset. But the eventual
665 KeyError would always report the empty frozenset([]) as the missing key. Now
666 it correctly refers to the initial element.
667
Antoine Pitrouae5bece2008-12-06 21:29:24 +0000668- Issue #4509: Various issues surrounding resize of bytearray objects to
669 which there are buffer exports.
670
Benjamin Peterson8d5934b2008-12-27 18:24:11 +0000671- Issue #4748: Lambda generators no longer return a value.

Matthias Klose91a3b9e2009-04-05 21:19:13 +0000680- Issue #1113244: Py_XINCREF, Py_DECREF, Py_XDECREF: Add `do { ... } while (0)'
681 to avoid compiler warnings.

Gregory P. Smith2b3eb372009-04-05 23:48:26 +0000683- Issue #5705: os.setuid() would not accept values > 2**31-1 but pwd.getpwnam()
684 returned them on 64bit platforms.
685
Walter Dörwalded960ac2009-05-03 22:36:33 +0000686- Issue #5108: Handle %s like %S and %R in PyUnicode_FromFormatV(): Call
687 PyUnicode_DecodeUTF8() once, remember the result and output it in a second
688 step. This avoids problems with counting UTF-8 bytes that ignores the effect
689 of using the replace error handler in PyUnicode_DecodeUTF8().
690
Walter Dörwald726ba8e2009-05-06 14:32:35 +0000691- Issue #3739: The unicode-internal encoder now reports the number of characters
692 consumed like any other encoder (instead of the number of bytes).
693
Benjamin Peterson91c12eb2009-12-03 02:52:39 +0000694- Issue #2422: When compiled with the ``--with-valgrind`` option, the
695 pymalloc allocator will be automatically disabled when running under
696 Valgrind. This gives improved memory leak detection when running
697 under Valgrind, while taking advantage of pymalloc at other times.

765
Nick Coghlan49868cb2009-11-15 07:30:34 +0000766- Issue #6816: runpy now provides a run_path function that allows Python code
767 to execute file paths that refer to source or compiled Python files as well
768 as zipfiles, directories and other valid sys.path entries that contain a

1934 leak-chasing test runs give sensible results. The previous method of

Amaury Forgeot d'Arc05e34492008-09-10 22:04:45 +00002079- Issue #3743: In a few places, PY_FORMAT_SIZE_T was incorrectly used with
2080 PyString_FromFormat or PyErr_Format to display size_t values. The macro
2081 PY_FORMAT_SIZE_T is designed to select the correct format for the OS
2082 ``printf`` function, whereas PyString_FromFormat has an independent
2083 implementation and uses "%zd" on all platforms for size_t values.
2084 This makes a difference on win64, where ``printf`` needs "%Id" to display
2085 64bit values.

2091 object; previously an int would be returned for small values. the __long__

Antoine Pitroud4ae97b2008-08-29 18:39:48 +00002102 was correctly parsed but parsing of subsequent arguments failed.

Vinay Sajip35e3b032008-09-01 14:33:59 +00002104- Issue #2534: speed up isinstance() and issubclass() by 50-70%, so as to
Antoine Pitrou0668c622008-08-26 22:42:08 +00002105 match Python 2.5 speed despite the __instancecheck__ / __subclasscheck__
2106 mechanism. In the process, fix a bug where isinstance() and issubclass(),
2107 when given a tuple of classes as second argument, were looking up
2108 __instancecheck__ / __subclasscheck__ on the tuple rather than on each
2109 type object.

2254-----------------
2255
Guido van Rossumf8402962008-08-20 15:01:50 +00002256- Issue #1878: Remove Py_TPFLAGS_HAVE_VERSION_TAG from
2257 Py_TPFLAGS_DEFAULT when not building the core. This means 3rd party
2258 extensions do not automatically benefit from the class attribute
2259 cache; they will have to explicitly add Py_TPFLAGS_HAVE_VERSION_TAG
2260 to their tp_flags field if they care. This is a backwards
2261 compatibility feature; in 3.0, all types will use the cache by
2262 default.
2263
Benjamin Petersonf647dc12008-08-20 01:27:30 +00002264- Keyword arguments can now follow starred arguments. (``f(a, *args,

Mark Dickinsonb6467572008-08-04 21:30:09 +00002277- Issue #1481296: Make long(float('nan')) and int(float('nan')) raise
2278 ValueError consistently across platforms.
2279
Amaury Forgeot d'Arc39fd6722008-07-31 21:28:03 +00002280- Issue #3479: On platforms where sizeof(int) is smaller than sizeof(long)
2281 (64bit Unix, for example), unichr() would truncate its argument and return
2282 u'\x00' for unichr(2**32). Now it properly raises an OverflowError.
2283
Neal Norwitze7d8be82008-07-31 17:17:14 +00002284- Apply security patches from Apple.

Amaury Forgeot d'Arc246daed2008-07-31 00:42:16 +00002286- Issue #2542: Now that issubclass() may call arbitrary code, ensure that
2287 PyErr_ExceptionMatches returns 0 when an exception occurs there.
2288
Antoine Pitrou92f82162008-07-25 22:22:08 +00002289- Issue #1819: function calls with several named parameters are now on
2290 average 35% faster (as measured by pybench).
2291
Amaury Forgeot d'Arce4921fe2008-07-21 22:00:38 +00002292- Issue #2378: An unexpected UnboundLocalError or NameError could appear when
2293 the python debugger steps into a class statement: the free variables (local
2294 variables defined in an outer scope) would be deleted from the outer scope.
2295
Gregory P. Smith0470bab2008-07-22 04:46:32 +00002296- Issue #2620: Overflow checking when allocating or reallocating memory
2297 was not always being done properly in some python types and extension
2298 modules. PyMem_MALLOC, PyMem_REALLOC, PyMem_NEW and PyMem_RESIZE have
2299 all been updated to perform better checks and places in the code that
2300 would previously leak memory on the error path when such an allocation
2301 failed have been fixed.

2310
Amaury Forgeot d'Arc351ffb82008-08-18 19:23:47 +00002311- Issue #2234: distutils failed for some versions of the cygwin compiler. The
2312 version reported by these tools does not necessarily follow the python
2313 version numbering scheme, so the module is less strict when parsing it.
2314
Nick Coghlanf70385a2008-08-18 12:42:46 +00002315- Issue #2235: Added Py3k warnings for types which will become unhashable
2316 under the stricter __hash__ inheritance rules in 3.0. Several types
2317 which did not meet the rules for hash invariants and were already
2318 unhashable in 3.0 have now been explicitly flagged as unhashable in
2319 2.6 as well (collections.Mapping, collections.Set, unittest.TestSuite,
2320 xml.dom.minidom.NamedNodeMap, numbers.Number, UserList.UserList)
2321
Brett Cannon88f801d2008-08-18 00:46:22 +00002322- Update __all__ for cookielib, csv, os, urllib2, and weakref to include things

Brett Cannonbf3157b2008-08-14 05:00:03 +00002353- Silence the DeprecationWarning of rfc822 when it is imported by mimetools
2354 since mimetools itself is deprecated. Because modules are cached, all
2355 subsequent imports of rfc822 will not raise a visible DeprecationWarning.
2356
Antoine Pitrou9fcd4b32008-08-11 17:21:36 +00002357- Issue #3134: shutil referenced undefined WindowsError symbol.

2369 to _sre.compile() will now be rejected. This should not affect anybody
2370 since the re.compile() function never generates invalid re-bytecode.

Skip Montanaroa032bf42008-08-08 22:52:51 +00002372- Issue #3436: Make csv.DictReader's fieldnames attribute a property so that
2373 upon first access it can be automatically initialized from the csv file if
2374 it wasn't initialized during instantiation.
2375
Brett Cannon3aa2a492008-08-06 22:28:09 +00002376- Issue #2338: Create imp.reload() to help with transitioning to Python 3.0 as
2377 the reload() built-in has been removed.
2378
Brett Cannon7e30b672008-08-04 21:52:25 +00002379- Changed code in the following modules/packages to remove warnings raised

2388 raised an AttributeError.
2389
Benjamin Peterson01a24322008-07-28 23:35:27 +00002390- Issue #2523: Fix quadratic behaviour when read()ing a binary file without
Antoine Pitroude781a42008-08-09 12:43:23 +00002391 asking for a specific length. This problem only affected files opened
2392 using the new "io" module, not the built-in open() function.
Benjamin Peterson01a24322008-07-28 23:35:27 +00002393

Antoine Pitrou5fdfa3e2008-07-25 19:42:26 +00002417- Issue #3394: zipfile.writestr sets external attributes when passed a
2418 file name rather than a ZipInfo instance, so files are extracted with
2419 mode 0600 rather than 000 under Unix.
2420
Gregory P. Smitha36f8fe2008-08-04 00:13:29 +00002421- Issue #1857: subprocess.Popen.poll gained an additional _deadstate keyword
2422 argument in python 2.5, this broke code that subclassed Popen to include its

Nick Coghlan6e8fef02008-08-18 13:14:22 +00002433- Issue #2235: the C API function PyObject_HashNotImplemented and its
2434 interaction with the tp_hash slot (added in 2.6b2) are now documented
2435
Nick Coghlan2a0c2b12008-08-04 12:47:17 +00002436- Issue #643841: The language reference now provides more detailed
2437 coverage of the lookup process for special methods. The disclaimers
2438 regarding lack of coverage of new-style classes have also been
2439 removed, since the coverage is now fairly reasonable.

Raymond Hettingere3ae6552008-06-20 04:18:15 +00002447Core and Builtins
2448-----------------
2449
Georg Brandl3e483f62008-07-16 22:57:41 +00002450- Issue #3156: Fix inconsistent behavior of the bytearray type: all
2451 its methods now allow for items objects that can be converted to
2452 an integer using operator.index().
2453
Mark Dickinson64b7e502008-07-16 09:40:03 +00002454- Issue #3360: Fix incorrect parsing of '020000000000.0', which
2455 produced a ValueError instead of giving the correct float.
2456
Eric Smitha5fa5a22008-07-16 00:11:49 +00002457- Issue #3083: Add alternate (#) formatting for bin, oct, hex output
2458 for str.format(). This adds the prefix 0b, 0o, or 0x, respectively.
2459
Mark Dickinson7103aa42008-07-15 19:08:33 +00002460- Issue #3008: the float type has a new instance method 'float.hex'
2461 and a new class method 'float.fromhex' to convert floating-point
2462 numbers to and from hexadecimal strings, respectively.
2463
Nick Coghlan6d6bd442008-07-15 15:40:22 +00002464- Issue #2235: __hash__ is once again inherited by default. To allow
2465 collections.Hashable to remain meaningful in the presence of the
2466 default hash implementation (object.__hash__), it is now possible
2467 to explicit block inheritance of hash by setting __hash__=None at
2468 the Python level, or tp_hash=PyObject_HashNotImplemented at the C
2469 level.
2470
Nick Coghlanb028f502008-07-13 14:52:36 +00002471- Issue #3221: Issue a RuntimeWarning instead of raising SystemError if
2472 the parent module cannot be found while performing an absolute import.
2473 This means that an incorrectly defined __package__ attribute will
2474 now only prevent relative imports in that module rather than causing
2475 all imports from that module to fail.
2476
Nick Coghlan14ff9942008-07-08 14:21:42 +00002477- Issue #2517: Allow unicode messages in Exceptions again by correctly
2478 bypassing the instance dictionary when looking up __unicode__ on
2479 new-style classes.
2480
Amaury Forgeot d'Arcbdd941f2008-07-01 20:38:04 +00002481- Issue #3242: Fix a crash inside the print statement, if sys.stdout is
2482 set to a custom object whose write() method happens to install
2483 another file in sys.stdout.
2484
Amaury Forgeot d'Arc1f40c8a2008-06-30 22:42:40 +00002485- Issue #3088: Corrected a race condition in classes derived from
2486 threading.local: the first member set by a thread could be saved in
2487 another thread's dictionary.
2488
Mark Dickinson1ec2fcd2008-06-20 14:53:43 +00002489- Issue #3004: Minor change to slice.indices(): the start and stop
2490 arguments are now treated identically, making the behaviour easier
2491 to describe and understand. For example, slice(None, -10,
2492 1).indices(9) now returns (0, 0, 1) instead of (0, -1, 1), and
2493 slice(None, 10, -1).indices(10) returns (9, 9, -1) instead of (9,
2494 10, -1).
2495
Georg Brandl278fc502008-07-19 12:46:12 +00002496- Issue #3219: Calling a function with repeated keyword arguments,
2497 f(a=2, a=23), would not cause a syntax error. This was a regression
2498 from 2.4 caused by the switch to the new compiler.
Benjamin Peterson175e4d92008-07-01 19:34:52 +00002499
Georg Brandl278fc502008-07-19 12:46:12 +00002500- Issue #2862: Make int and float freelist management consistent with
2501 other freelists. Changes their CompactFreeList apis into
2502 ClearFreeList apis and calls them via gc.collect().
Gregory P. Smith2fe77062008-07-06 03:35:58 +00002503

2505-------
2506
Thomas Heller57adf222008-08-14 19:10:48 +00002507- Issue #3554: ctypes.string_at and ctypes.wstring_at did call Python
2508 api functions without holding the GIL, which could lead to a fatal
2509 error when they failed.
2510
Martin v. Löwisaabf4042008-08-02 07:20:25 +00002511- Issue #799428: Fix Tkinter.Misc._nametowidget to unwrap Tcl command objects.

2520 ForkingPickler.register() to resolve conflict with ctypes.
2521
Vinay Sajip51e65192008-07-18 09:01:10 +00002522- Issue #3090: Fixed ARCHFLAGS parsing on OS/X

2525 a valid dlerror() message.
2526
Thomas Heller2bad6572008-07-15 17:19:50 +00002527- Issue #3258: Fixed a crash when a ctypes POINTER type to an
2528 incomplete structure was created.
2529
Brett Cannon3d0b9f02008-07-13 01:15:07 +00002530- Issue #3339: dummy_thread.acquire() should not return None.

Raymond Hettingerb01713e2008-07-10 14:34:57 +00002532- Issue #3285: Fractions from_float() and from_decimal() accept Integral arguments.
2533
Andrew M. Kuchlingcc3f2b12008-07-10 14:43:31 +00002534- Issue #3301: Bisect module behaved badly when lo was negative.
Raymond Hettinger3cd1e422008-07-10 14:03:19 +00002535
Amaury Forgeot d'Arc0f7cddc2008-07-06 21:34:39 +00002536- Issue #839496: SimpleHTTPServer used to open text files in text mode. This is
2537 both unnecessary (HTTP allows text content to be sent in several forms) and
Andrew M. Kuchlingcc3f2b12008-07-10 14:43:31 +00002538 wrong because the actual transmitted size could differ from the
Amaury Forgeot d'Arc0f7cddc2008-07-06 21:34:39 +00002539 content-length. The problem had been corrected in the 2.4 branch, but never
2540 merged into trunk.
2541
Georg Brandle78fbcc2008-07-05 10:13:36 +00002542- Issue #2663: add filtering capability to shutil.copytree().

2548- Issue #1746: Correct handling of zipfile archive comments (previously
2549 archives with comments over 4k were flagged as invalid). Allow writing
Vinay Sajip51e65192008-07-18 09:01:10 +00002550 Zip files with archives by setting the 'comment' attribute of a ZipFile.

2947 mode or even as a 4-way universal binary (that is, PPC, i386,
Georg Brandl5cc774e2008-06-11 20:28:06 +00002948 PPC64 and x86_64 support in one binary).
Ronald Oussoren5640ce22008-06-05 12:58:24 +00002949
2950 This is controlled by the configure argument ``--with-universal-archs``:
2951
2952 - ``--with-universal-archs=all``: install 4-way universal
2953
2954 - ``--with-universal-archs=32-bit``: install 2-way universal, 32-bit (the default)
2955
2956 - ``--with-universal-archs=64-bit``: install 2-way universal, 64-bit
2957
2958 This option should be used in combination with ``--enable-universalsdk=``.
2959
2960 NOTE: 64-bit and 4-way builds are only suppported on Mac OS X 10.5 (or later).

Georg Brandl3ee81df2008-05-17 18:14:43 +00003010- Issue #1631171: Re-implement the 'warnings' module in C (the
3011 original Python code has been kept as backup). This will allow for
3012 using the 'warning's machinery in such places as the parser where
3013 use of pure Python code is not possible. Both the ``showarning()``
3014 and ``formatwarning()`` gain an optional 'line' argument which is
3015 not called by default for backwards-compatibility reasons. Setting
3016 ``warnings.showwarning()`` to an implementation that lacks support
3017 for the ``line`` argument will raise a DeprecationWarning.

Georg Brandl3ee81df2008-05-17 18:14:43 +00003080- Issue #2550: The approach used by client/server code for obtaining
3081 ports to listen on in network-oriented tests has been refined in an
3082 effort to facilitate running multiple instances of the entire
3083 regression test suite in parallel without issue.
3084 test_support.bind_port() has been fixed such that it will always
3085 return a unique port -- which wasn't always the case with the
3086 previous implementation, especially if socket options had been set
3087 that affected address reuse (i.e. SO_REUSEADDR, SO_REUSEPORT). The
3088 new implementation of bind_port() will actually raise an exception
3089 if it is passed an AF_INET/SOCK_STREAM socket with either the
3090 SO_REUSEADDR or SO_REUSEPORT socket option set. Furthermore, if
3091 available, bind_port() will set the SO_EXCLUSIVEADDRUSE option on
3092 the socket it's been passed. This currently only applies to
3093 Windows. This option prevents any other sockets from binding to the
3094 host/port we've bound to, thus removing the possibility of the
3095 'non-deterministic' behaviour, as Microsoft puts it, that occurs
3096 when a second SOCK_STREAM socket binds and accepts to a host/port
3097 that's already been bound by another socket. The optional preferred
3098 port parameter to bind_port() has been removed. Under no
3099 circumstances should tests be hard coding ports!
3100
3101 test_support.find_unused_port() has also been introduced, which will
3102 pass a temporary socket object to bind_port() in order to obtain an
3103 unused port. The temporary socket object is then closed and
3104 deleted, and the port is returned. This method should only be used
3105 for obtaining an unused port in order to pass to an external program
3106 (i.e. the -accept [port] argument to openssl's s_server mode) or as
3107 a parameter to a server-oriented class that doesn't give you direct
3108 access to the underlying socket used.
3109
3110 Finally, test_support.HOST has been introduced, which should be used
3111 for the host argument of any relevant socket calls (i.e. bind and
3112 connect).
Trent Nelsone41b0062008-04-08 23:47:30 +00003113

3386Core and builtins
3387-----------------
3388
Fred Drakea8ee94b2008-03-01 02:45:07 +00003389- Issue #2051: pyc and pyo files are no longer created with permission
Barry Warsaw52973612008-03-01 02:23:38 +00003390 644. The mode is now inherited from the py file.
Christian Heimes40346852008-02-23 17:52:07 +00003391
Georg Brandlad61bc82008-02-23 15:11:18 +00003392- Issue #2067: file.__exit__() now calls subclasses' close() method.
3393
3394- Patch #1759: Backport of PEP 3129 class decorators.
Christian Heimes5224d282008-02-23 15:01:05 +00003395
Vinay Sajipb7edfc42008-04-02 21:10:23 +00003396- Issue #1881: An internal parser limit has been increased. Also see
Facundo Batistafc2d0102008-02-23 12:01:13 +00003397 issue 215555 for a discussion.
3398
Eric Smitha73fbe72008-02-23 03:09:44 +00003399- Added the future_builtins module, which contains hex() and oct().
3400 These are the PEP 3127 version of these functions, designed to be
3401 compatible with the hex() and oct() builtins from Python 3.0. They
3402 differ slightly in their output formats from the existing, unchanged
3403 Python 2.6 builtins. The expected usage of the future_builtins
3404 module is:
3405 from future_builtins import hex, oct
3406
Eric Smith7ef40bf2008-02-20 23:34:22 +00003407- Issue #1600: Modifed PyOS_ascii_formatd to use at most 2 digit
3408 exponents for exponents with absolute value < 100. Follows C99
3409 standard. This is a change on Windows, which would use 3 digits.
3410 Also, added 'n' to the formats that PyOS_ascii_formatd understands,
3411 so that any alterations it does to the resulting string will be
3412 available in stringlib/formatter.h (for float.__format__).
3413
Eric Smith5a3c1352008-02-19 13:21:56 +00003414- Implemented PEP 3101, Advanced String Formatting. This adds a new
3415 builtin format(); a format() method for str and unicode; a
3416 __format__() method to object, str, unicode, int, long, float, and
3417 datetime; the class string.Formatter; and the C API
3418 PyObject_Format().
3419
Georg Brandl3ee81df2008-05-17 18:14:43 +00003420- Fixed several potential crashes, all caused by specially crafted
3421 __del__ methods exploiting objects in temporarily inconsistent
3422 state.
Amaury Forgeot d'Arc632fad32008-02-16 20:55:24 +00003423
Vinay Sajipb7edfc42008-04-02 21:10:23 +00003424- Issue #2115: Important speedup in setting __slot__ attributes. Also
Georg Brandl3ee81df2008-05-17 18:14:43 +00003425 prevent a possible crash: an Abstract Base Class would try to access
3426 a slot on a registered virtual subclass.
Amaury Forgeot d'Arc60d6c7f2008-02-15 21:22:45 +00003427
Georg Brandl3ee81df2008-05-17 18:14:43 +00003428- Fixed repr() and str() of complex numbers with infinity or nan as
3429 real or imaginary part.
Christian Heimes2f0da532008-02-15 06:57:08 +00003430
Georg Brandl3ee81df2008-05-17 18:14:43 +00003431- Clear all free lists during a gc.collect() of the highest generation
3432 in order to allow pymalloc to free more arenas. Python may give back
3433 memory to the OS earlier.
Christian Heimes3b718a72008-02-14 12:47:33 +00003434
Georg Brandl3ee81df2008-05-17 18:14:43 +00003435- Issue #2045: Fix an infinite recursion triggered when printing a
3436 subclass of collections.defaultdict, if its default_factory is set
3437 to a bound method.
Amaury Forgeot d'Arcb01aa432008-02-08 00:56:02 +00003438
Christian Heimesf75dbef2008-02-08 00:11:31 +00003439- Fixed a minor memory leak in dictobject.c. The content of the free
3440 list was not freed on interpreter shutdown.
3441
Georg Brandl3ee81df2008-05-17 18:14:43 +00003442- Limit free list of method and builtin function objects to 256
3443 entries each.
Christian Heimes6075a822008-02-06 12:44:34 +00003444
Georg Brandl3ee81df2008-05-17 18:14:43 +00003445- Patch #1953: Added ``sys._compact_freelists()`` and the C API
3446 functions ``PyInt_CompactFreeList`` and ``PyFloat_CompactFreeList``
Christian Heimes422051a2008-02-04 18:00:12 +00003447 to compact the internal free lists of pre-allocted ints and floats.
3448
Georg Brandl3ee81df2008-05-17 18:14:43 +00003449- Issue #1983: Fixed return type of fork(), fork1() and forkpty()
3450 calls. Python expected the return type int but the fork familie
3451 returns pi_t.
Christian Heimes951cc0f2008-01-31 23:08:23 +00003452
Georg Brandl3ee81df2008-05-17 18:14:43 +00003453- Issue #1678380: Fix a bug that identifies 0j and -0j when they
3454 appear in the same code unit.
Mark Dickinson105be772008-01-31 22:17:37 +00003455
Georg Brandl3ee81df2008-05-17 18:14:43 +00003456- Issue #2025: Add tuple.count() and tuple.index() methods to comply
3457 with the collections.Sequence API.
Raymond Hettinger5b07ebc2008-02-07 00:54:20 +00003458
Georg Brandl3ee81df2008-05-17 18:14:43 +00003459- Patch #1970 by Antoine Pitrou: Speedup unicode whitespace and
3460 linebreak detection
Christian Heimes4d4f2702008-01-30 11:32:37 +00003461
Georg Brandl3ee81df2008-05-17 18:14:43 +00003462- Added ``PyType_ClearCache()`` and ``sys._clear_type_cache`` to clear
3463 the internal lookup cache for ref leak tests.
Christian Heimes908caac2008-01-27 23:34:59 +00003464
Georg Brandl3ee81df2008-05-17 18:14:43 +00003465- Patch #1473257: generator objects gain a gi_code attribute. This is
3466 the same object as the func_code attribute of the function that
3467 produced the generator.
Georg Brandl0cdf9a32008-01-26 14:14:20 +00003468
Georg Brandl3ee81df2008-05-17 18:14:43 +00003469- Issue #1920: "while 0" statements were completely removed by the
3470 compiler, even in the presence of an "else" clause, which is
3471 supposed to be run when the condition is false. Now the compiler
3472 correctly emits bytecode for the "else" suite.
Amaury Forgeot d'Arc31eaafe2008-01-24 22:59:25 +00003473
Guido van Rossumeead05f2008-01-24 18:21:02 +00003474- A few crashers fixed: weakref_in_del.py (issue #1377858);
3475 loosing_dict_ref.py (issue #1303614, test67.py);
3476 borrowed_ref_[34].py (not in tracker).
3477
Vinay Sajipd7cf32e2008-01-24 12:43:33 +00003478- Issue #1069410: The "can't load dll" message box on Windows is
Christian Heimesb2302ba2008-01-23 17:15:06 +00003479 suppressed while an extension is loaded by calling SetErrorMode in
3480 dynload_win.c. The error is still reported properly.
3481
Georg Brandl3ee81df2008-05-17 18:14:43 +00003482- Issue #1915: Python compiles with --enable-unicode=no again. However
Christian Heimes082c9b02008-01-23 14:20:50 +00003483 several extension methods and modules do not work without unicode
3484 support.
3485
Georg Brandl26543b12008-01-21 18:36:51 +00003486- Issue #1882: when compiling code from a string, encoding cookies in the
3487 second line of code were not always recognized correctly.
3488
Georg Brandl14404b62008-01-19 19:27:05 +00003489- Issue #1679: "0x" was taken as a valid integer literal.
3490
Georg Brandl6caad7d2008-01-26 14:19:22 +00003491- Issue #1865: ``bytes`` as an alias for ``str`` and b"" as an alias "" were
Christian Heimes288e89a2008-01-18 18:24:07 +00003492 added.
3493
Christian Heimesc94e2b52008-01-14 04:13:37 +00003494- sys.float_info / PyFloat_GetInfo: The floating point information
3495 object was converted from a dict to a specialized structseq object.
3496
Georg Brandl3ee81df2008-05-17 18:14:43 +00003497- Patch #1816: Added sys.flags structseq. It exposes the status of
3498 most command line arguments and PYTHON* environment variables.
Christian Heimesf31b69f2008-01-14 03:42:48 +00003499
Georg Brandl3ee81df2008-05-17 18:14:43 +00003500- Objects/structseq.c: Implemented new structseq representation. The
3501 patch makes structseqs (e.g. the return value of os.stat) more
3502 readable.
Christian Heimes9c201962008-01-14 03:33:52 +00003503
Georg Brandl3ee81df2008-05-17 18:14:43 +00003504- Patch #1700288: added a type attribute cache that caches method
3505 accesses, resulting in speedups in heavily object-oriented code.
Amaury Forgeot d'Arce4c270c2008-01-14 00:29:41 +00003506
Neal Norwitz3fc15b82008-01-10 05:42:58 +00003507- Bug #1776: __import__() no longer accepts filenames on any platform.
3508 The first parameter to __import__() must be a valid module name.
Christian Heimes3403f152008-01-09 19:56:33 +00003509
Georg Brandlaed6c662008-01-07 17:25:53 +00003510- Patch #1668: renamed THREADDEBUG envvar to PYTHONTHREADDEBUG.
3511
Georg Brandl3ee81df2008-05-17 18:14:43 +00003512- Patch #602345: Add -B command line option, PYTHONDONTWRITEBYTECODE
3513 envvar and sys.dont_write_bytecode attribute. All these can be set
3514 to forbid Python to attempt to write compiled bytecode files.
Georg Brandl2da0fce2008-01-07 17:09:35 +00003515
Georg Brandl3ee81df2008-05-17 18:14:43 +00003516- Improve some exception messages when Windows fails to load an
3517 extension module. Now we get for example '%1 is not a valid Win32
3518 application' instead of 'error code 193'.
Amaury Forgeot d'Arce0b76952008-01-04 02:04:15 +00003519
Georg Brandl3ee81df2008-05-17 18:14:43 +00003520- Bug #1481296: Fixed long(float('nan')) != 0L.

Georg Brandl3ee81df2008-05-17 18:14:43 +00003522- Issue #1640: Added math.isinf(x), math.isnan(x) and math.copysign(x,
3523 y) functions.
Christian Heimese2ca4242008-01-03 20:23:15 +00003524
Christian Heimes0a8143f2007-12-18 23:22:54 +00003525- Issue #1635: Platform independent creation and representation of NaN
Georg Brandl3ee81df2008-05-17 18:14:43 +00003526 and INF. float("nan"), float("inf") and float("-inf") now work on
3527 every platform with IEEE 754 semantics.
Christian Heimes0a8143f2007-12-18 23:22:54 +00003528
Georg Brandl3ee81df2008-05-17 18:14:43 +00003529- Compiler now generates simpler and faster code for dictionary
3530 literals. The oparg for BUILD_MAP now indicates an estimated
3531 dictionary size. There is a new opcode, STORE_MAP, for adding
3532 entries to the dictionary.
Raymond Hettingerfd7ed402007-12-18 21:24:09 +00003533
Georg Brandl3ee81df2008-05-17 18:14:43 +00003534- Issue #1638: %zd configure test fails on Linux.

Georg Brandl3ee81df2008-05-17 18:14:43 +00003536- Issue #1620: New property decorator syntax was modifying the
3537 decorator in place instead of creating a new decorator object.
Christian Heimes90e10e72007-12-14 02:35:23 +00003538
Georg Brandl3ee81df2008-05-17 18:14:43 +00003539- Issue #1538: Avoid copying string in split/rsplit if the split char
3540 is not found.
Skip Montanaro26015492007-12-08 15:33:24 +00003541
Andrew M. Kuchling395fe442007-12-05 13:27:20 +00003542- Issue #1553: An erroneous __length_hint__ can make list() raise a
Christian Heimes7cc1c6f2007-12-05 12:52:34 +00003543 SystemError.
3544
Nick Coghlanef01d822007-12-03 12:55:17 +00003545- PEP 366: Allow explicit relative imports when executing modules

3547 __package__ attribute.
3548
Georg Brandl3ee81df2008-05-17 18:14:43 +00003549- Issue #1402: Fix a crash on exit, when another thread is still
3550 running, and if the deallocation of its frames somehow calls the
3551 PyGILState_Ensure() / PyGILState_Release() functions.
Amaury Forgeot d'Arcbe49a902007-11-30 20:37:22 +00003552

3562 file can now be directly executed by passing their name to the
3563 interpreter. The directory/zipfile is automatically inserted as the
3564 first entry in sys.path.
Nick Coghlan327a39b2007-11-18 11:56:28 +00003565
Georg Brandl3ee81df2008-05-17 18:14:43 +00003566- Issue #1265: Fix a problem with sys.settrace, if the tracing
3567 function uses a generator expression when at the same time the
3568 executed code is closing a paused generator.
Amaury Forgeot d'Arc0d75f092007-11-13 21:54:28 +00003569
Raymond Hettinger1760c8a2007-11-08 02:52:43 +00003570- sets and frozensets now have an isdisjoint() method.
3571
Raymond Hettinger3f8caa32007-10-24 01:28:33 +00003572- optimize the performance of builtin.sum().
3573
Neal Norwitz44f326e2007-10-05 05:29:17 +00003574- Fix warnings found by the new version of the Coverity checker.
3575
Georg Brandl3ee81df2008-05-17 18:14:43 +00003576- The enumerate() builtin function is no longer bounded to sequences
3577 smaller than LONG_MAX. Formerly, it raised an OverflowError. Now,
3578 automatically shifts from ints to longs.
Raymond Hettinger8f669372007-10-03 21:18:11 +00003579
Georg Brandl3ee81df2008-05-17 18:14:43 +00003580- Issue #1686386: Tuple's tp_repr did not take into account the
3581 possibility of having a self-referential tuple, which is possible
3582 from C code. Nor did object's tp_str consider that a type's tp_str
3583 could do something that could lead to an inifinite recursion.
3584 Py_ReprEnter() and Py_EnterRecursiveCall(), respectively, fixed the
3585 issues.
Brett Cannon0b14f242007-09-30 19:45:10 +00003586
Georg Brandl3ee81df2008-05-17 18:14:43 +00003587- Issue #1164: It was possible to trigger deadlock when using the
3588 'print' statement to write to a file since the GIL was not released
3589 as needed. Now PyObject_Print() does the right thing along with
3590 various tp_print implementations of the built-in types and those in
3591 the collections module.
Brett Cannon01531592007-09-17 03:28:34 +00003592
Georg Brandl3ee81df2008-05-17 18:14:43 +00003593- Issue #1147: Exceptions were directly allowing string exceptions in
3594 their throw() method even though string exceptions no longer
3595 allowed.
Brett Cannon4c20bc42007-09-11 21:02:28 +00003596
Georg Brandl3ee81df2008-05-17 18:14:43 +00003597- Issue #1096: Prevent a segfault from getting the repr of a very

Brett Cannon1e534b52007-09-07 04:18:30 +00003600- Issue #1202533: Fix infinite recursion calls triggered by calls to
Georg Brandl3ee81df2008-05-17 18:14:43 +00003601 PyObject_Call() never calling back out to Python code to trigger
3602 recursion depth updates/checks. Required the creation of a static
3603 RuntimeError instance in case normalizing an exception put the
3604 recursion check value past its limit. Fixes crashers
3605 infinite_rec_(1|2|4|5).py.

Georg Brandl3ee81df2008-05-17 18:14:43 +00003621 __*__ attributes. (Some already existed, e.g., __doc__ and
3622 __name__.)
Neal Norwitz0ac60192007-05-27 04:08:54 +00003623
Neal Norwitz8b2bfbc2007-05-23 06:35:32 +00003624- Add -3 option to the interpreter to warn about features that are

Georg Brandl3ee81df2008-05-17 18:14:43 +00003631 "except E as target:". This is to provide forwards compatibility
3632 with Python 3.0.
Collin Winter62903052007-05-18 23:11:24 +00003633
Brett Cannon229cee22007-05-05 01:34:02 +00003634- Deprecate BaseException.message as per PEP 352.

3652
Guido van Rossum143b5642007-03-23 04:58:42 +00003653- Bug #1683368: The object.__init__() and object.__new__() methods are
3654 now stricter in rejecting excess arguments. The only time when
3655 either allows excess arguments is when it is not overridden and the
3656 other one is. For backwards compatibility, when both are
3657 overridden, it is a deprecation warning (for now; maybe a Py3k
Guido van Rossum234b1ff2007-03-23 19:39:01 +00003658 warning later). Also, type.__init__() insists on the same signature
3659 as supported by type.__new__().
Guido van Rossum143b5642007-03-23 04:58:42 +00003660
Georg Brandl3ee81df2008-05-17 18:14:43 +00003661- Patch #1675423: PyComplex_AsCComplex() now tries to convert an
3662 object to complex using its __complex__() method before falling back
3663 to the __float__() method. Therefore, the functions in the cmath
3664 module now can operate on objects that define a __complex__()
3665 method.

3682
Georg Brandl7b9c5552007-03-12 14:30:05 +00003683- Bug #1678647: write a newline after printing an exception in any
3684 case, even when converting the value to a string failed.
3685
Georg Brandl871f1bc2007-03-12 13:17:36 +00003686- The dir() function has been extended to call the __dir__() method on
Georg Brandl3ee81df2008-05-17 18:14:43 +00003687 its argument, if it exists. If not, it will work like before. This
3688 allows customizing the output of dir() in the presence of a
3689 __getattr__().

Collin Winter276887b2007-03-12 16:11:39 +00003691- Patch #922167: Python no longer segfaults when faced with infinitely
3692 self-recursive reload() calls (as reported by bug #742342).
3693

3698 parthensized forms. This means complex(repr(x)) now works instead of
3699 raising a ValueError.
Collin Wintere38051d2007-03-09 20:33:07 +00003700
Georg Brandlaa2321b2007-03-07 00:40:28 +00003701- Patch #703779: unset __file__ in __main__ after running a file. This
Georg Brandl3ee81df2008-05-17 18:14:43 +00003702 makes the filenames the warning module prints much more sensible
3703 when a PYTHONSTARTUP file is used.
Georg Brandlaa2321b2007-03-07 00:40:28 +00003704

Georg Brandl0fca97a2007-03-05 22:28:08 +00003716- Patch #1674228: when assigning a slice (old-style), check for the
3717 sq_ass_slice instead of the sq_slice slot.
3718
Georg Brandl3ee81df2008-05-17 18:14:43 +00003719- When printing an unraisable error, don't print exceptions. before

Georg Brandl3ee81df2008-05-17 18:14:43 +00004345- unittest now verifies more of its assumptions. In particular,
4346 TestCase and TestSuite subclasses (not instances) are no longer
4347 accepted in TestSuite.addTest(). This should cause no
4348 incompatibility since it never made sense with ordinary subclasses
4349 -- the failure just occurred later, with a more cumbersome
4350 exception.

Georg Brandl3ee81df2008-05-17 18:14:43 +00004631- Issue #829951: In the smtplib module, SMTP.starttls() now complies
4632 with RFC 3207 and forgets any knowledge obtained from the server not
4633 obtained from the TLS negotiation itself. Patch contributed by Bill
4634 Fenner.
Gregory P. Smith2b3ba582008-01-17 08:03:17 +00004635
Georg Brandl3ee81df2008-05-17 18:14:43 +00004636- Issue #1339: The smtplib.SMTP class has been refactored a bit such
Gregory P. Smithbde4ae42008-01-17 08:35:49 +00004637 that the SMTP.starttls() caller no longer needs to call ehlo()
4638 beforehand. SMTP.starttls() now raises an exception of the server
Georg Brandl3ee81df2008-05-17 18:14:43 +00004639 does not claim to support starttls. Adds the
4640 SMTP.ehlo_or_helo_if_needed() method. Patch contributed by Bill

4721 complex, tuple, list, dict, set, and frozenset. Formerly, it would
4722 silently miscode subclasses of those types. Now, it raises a

Georg Brandl3ee81df2008-05-17 18:14:43 +00004739 time so that opening a database previously created with the DB_DUP
4740 or DB_DUPSORT flag set will keep the proper behavior on subsequent
4741 opens. Specifically: dictionary assignment to a DB object will
4742 replace all values for a given key when the database allows
4743 duplicate values. DB users should use DB.put(k, v) when they want
4744 to store duplicates; not DB[k] = v.
Gregory P. Smithec10a4a2007-11-05 02:32:26 +00004745

4751 characters with ASCII value less than 32. Also, it correctly quotes
4752 dots only if they occur on a single line, as opposed to the previous
4753 behavior of quoting dots if they are the second character of any
4754 line.

Georg Brandl3ee81df2008-05-17 18:14:43 +00005084- ``PySet_Add()`` can now modify a newly created frozenset. Similarly
5085 to ``PyTuple_SetItem``, it can be used to populate a brand new
5086 frozenset; but it does not steal a reference to the added item.
Amaury Forgeot d'Arccab3d982008-02-03 22:51:43 +00005087
Vinay Sajipb7edfc42008-04-02 21:10:23 +00005088- Added ``PySet_Check()`` and ``PyFrozenSet_Check()`` to the set API.

Georg Brandl3ee81df2008-05-17 18:14:43 +00005090- Backport of PyUnicode_FromString(), _FromStringAndSize(), _Format
5091 and _FormatV from Python 3.0. Made PyLong_AsSsize_t and
5092 PyLong_FromSsize_t public functions.
Georg Brandl6caad7d2008-01-26 14:19:22 +00005093
5094- Patch #1720595: add T_BOOL to the range of structmember types.
5095
5096- Issue #1534: Added ``PyFloat_GetMax()``, ``PyFloat_GetMin()`` and
5097 ``PyFloat_GetInfo()`` to the float API.
5098
Georg Brandl3ee81df2008-05-17 18:14:43 +00005099- Issue #1521: On 64bit platforms, using PyArgs_ParseTuple with the t#
5100 of w# format code incorrectly truncated the length to an int, even
5101 when PY_SSIZE_T_CLEAN is set. The str.decode method used to return
5102 incorrect results with huge strings.
Georg Brandl6caad7d2008-01-26 14:19:22 +00005103
Georg Brandl3ee81df2008-05-17 18:14:43 +00005104- Issue #1629: Renamed Py_Size, Py_Type and Py_Refcnt to Py_SIZE,
5105 Py_TYPE and Py_REFCNT.
Georg Brandl6caad7d2008-01-26 14:19:22 +00005106
Georg Brandl3ee81df2008-05-17 18:14:43 +00005107- PEP 3123: Provide forward compatibility with Python 3.0, while
5108 keeping backwards compatibility. Add Py_Refcnt, Py_Type, Py_Size,
5109 and PyVarObject_HEAD_INIT.
Georg Brandl6caad7d2008-01-26 14:19:22 +00005110
Georg Brandl3ee81df2008-05-17 18:14:43 +00005111- Py_ssize_t fields work in structmember when HAVE_LONG_LONG is not
5112 defined.
Georg Brandl6caad7d2008-01-26 14:19:22 +00005113
5114- Patch #1733960: Allow T_LONGLONG to accept ints.
5115
5116- T_PYSSIZET can now be used in PyMemberDef lists for Py_ssize_t members.
5117
Christian Heimes000a0742008-01-03 22:16:32 +00005118- Added a new API function ``PyImport_ImportModuleNoBlock``.
5119
Georg Brandl6caad7d2008-01-26 14:19:22 +00005120- Bug #1637022: Prefix AST symbols with _Py_.
5121
5122- Fix some leftovers from the conversion from int to Py_ssize_t
5123 (relevant to strings and sequences of more than 2**31 items).
5124
5125- Make _PyGILState_NoteThreadState() static, it was not used anywhere
5126 outside of pystate.c and should not be necessary.
5127
Georg Brandl3ee81df2008-05-17 18:14:43 +00005128- ``PyImport_Import`` and ``PyImport_ImportModule`` now always do
5129 absolute imports. In earlier versions they might have used relative
5130 imports under some conditions.
Christian Heimes000a0742008-01-03 22:16:32 +00005131
Georg Brandl3ee81df2008-05-17 18:14:43 +00005132- Added case insensitive comparison methods ``PyOS_stricmp(char*,
5133 char*)`` and ``PyOS_strnicmp(char*, char*, Py_ssize_t)``.
Christian Heimes000a0742008-01-03 22:16:32 +00005134
Georg Brandl3ee81df2008-05-17 18:14:43 +00005135- Bug #1542693: remove semi-colon at end of PyImport_ImportModuleEx
5136 macro so it can be used as an expression.

5141
Georg Brandl3ee81df2008-05-17 18:14:43 +00005142- Patch #1706: Drop support for Win9x, WinME and NT4. Python now
5143 requires Windows 2000 or greater. The _WINVER and NTDDI_VERSION
5144 macros are set to Win2k for x86/32bit builds and WinXP for AMD64
5145 builds.
Christian Heimes95d64472008-02-09 19:55:22 +00005146
Georg Brandl3ee81df2008-05-17 18:14:43 +00005147- Conditionalize definition of _CRT_SECURE_NO_DEPRECATE and
5148 _CRT_NONSTDC_NO_DEPRECATE.

Brett Cannon791d56f2007-05-31 19:40:42 +00005158- buildtools now raises a DeprecationWarning.
5159
Georg Brandl3ee81df2008-05-17 18:14:43 +00005160- Removed the macfs module. It had been deprecated since Python 2.5.
5161 This lead to the deprecation of macostools.touched() as it relied
5162 solely on macfs and was a no-op under OS X.
