54Core and Builtins
55-----------------
56
Benjamin Petersonecdae192010-01-04 00:43:01 +000057- The __complex__ method is now looked up on the class of instances to make it
58 consistent with other special methods.
59
Antoine Pitrou5b7139a2010-01-02 21:12:58 +000060- Issue #7462: Implement the stringlib fast search algorithm for the `rfind`,
61 `rindex`, `rsplit` and `rpartition` methods. Patch by Florent Xicluna.
62
Mark Dickinson1b34d252010-01-01 17:27:30 +000063- Issue #5080: A number of functions and methods previously produced a
64 DeprecationWarning when passed a float argument where an integer was
65 expected. These functions and methods now raise TypeError instead.
66 The majority of the effects of this change are in the extension
67 modules, but some core functions and methods are affected: notably
68 the 'chr', 'range' and 'xrange' builtins, and many unicode/str
69 methods.
70
Benjamin Peterson0f02d392009-12-30 19:34:10 +000071- Issue #7604: Deleting an unset slotted attribute did not raise an
72 AttributeError.
73
Mark Dickinson99d652e2009-12-30 12:12:23 +000074- Issue #7534: Fix handling of IEEE specials (infinities, nans,
75 negative zero) in ** operator. The behaviour now conforms to that
76 described in C99 Annex F.
77
Amaury Forgeot d'Arcc8a2ce72009-12-29 23:06:17 +000078- Issue #7579: the msvcrt module now has docstrings for all its functions.
79
Amaury Forgeot d'Arc8645a5c2009-12-29 22:03:38 +000080- Issue #7413: Passing '\0' as the separator to datetime.datetime.isoformat()
81 used to drop the time part of the result.
82
Mark Dickinson46572832009-12-27 14:55:57 +000083- Issue #1811: improve accuracy and cross-platform consistency for
84 true division of integers: the result of a/b is now correctly
85 rounded for ints a and b (at least on IEEE 754 platforms), and in
86 particular does not depend on the internal representation of a long.
87
Ezio Melottif84caf42009-12-24 22:25:17 +000088- Issue #6108: unicode(exception) and str(exception) should return the same
89 message when only __str__ (and not __unicode__) is overridden in the subclass.
90
Ronald Oussoren92919a62009-12-24 13:30:58 +000091- Issue #6834: replace the implementation for the 'python' and 'pythonw'
92 executables on OSX.
93
94 These executables now work properly with the arch(1) command:
95 ``arch -ppc python`` will start a universal binary version of python
96 in PPC mode (unlike previous releases).
97
R. David Murray0a0a1a82009-12-14 16:28:26 +000098- Issue #1680159: unicode coercion during an 'in' operation no longer masks
99 the underlying error when the coercion fails for the left hand operand.
100

112 by Arfrever.
113
Antoine Pitrou80157252010-01-08 19:20:17 +0000114- Issue #7092: Remove py3k warning when importing cPickle. 2to3 handles
115 renaming of `cPickle` to `pickle`. The warning was annoying since there's
116 no alternative to cPickle if you care about performance. Patch by Florent
117 Xicluna.

126 and make it implement the `io.BufferedIOBase` ABC to allow for further
127 speedups by wrapping it in an `io.BufferedReader`. Patch by Nir Aides.
128
129- Issue #3972: httplib.HTTPConnection now accepts an optional source_address
Gregory P. Smith9d325212010-01-03 02:06:07 +0000130 parameter to allow specifying where your connections come from.

Senthil Kumaran7713acf2009-12-20 06:05:13 +0000148 Patch by Tatsuhiro Tsujikawa.
149
Benjamin Petersonddd392c2009-12-13 19:19:07 +0000150- Issue #7349: Make methods of file objects in the io module accept None as an
151 argument where file-like objects (ie StringIO and BytesIO) accept them to mean
152 the same as passing no argument.
153
Benjamin Petersonc4771d22009-12-13 17:31:31 +0000154- Issue #7348: StringIO.StringIO.readline(-1) now acts as if it got no argument
155 like other file objects.
156

223-----------------
224
Amaury Forgeot d'Arcd7288712009-12-01 21:51:04 +0000225- Issue #7419: setlocale() could crash the interpreter on Windows when called
226 with invalid values.
227
Eric Smithc4ab8332009-11-29 17:40:57 +0000228- Issue #3382: 'F' formatting for float and complex now convert the
229 result to upper case. This only affects 'inf' and 'nan', since 'f'
230 no longer converts to 'g' for large values.
Amaury Forgeot d'Arcd7288712009-12-01 21:51:04 +0000231
Mark Dickinson9dd5e162009-11-23 20:54:09 +0000232- Remove switch from "%f" formatting to "%g" formatting for floats
233 larger than 1e50 in absolute value.
234
Mark Dickinson18cfada2009-11-23 18:46:41 +0000235- Remove restrictions on precision when formatting floats. E.g.,
236 "%.120g" % 1e-100 used to raise OverflowError, but now gives the
237 requested 120 significant digits instead.
238
Benjamin Peterson89b1a5c2009-11-19 22:58:01 +0000239- Add Py3k warnings for parameter names in parenthesis.
240
Benjamin Peterson48f0a8d2009-11-19 23:19:29 +0000241- Issue #7362: Give a proper error message for def f((x)=3): pass.
Benjamin Peterson89b1a5c2009-11-19 22:58:01 +0000242
Ronald Oussoren315cd0c2009-11-19 16:25:21 +0000243- Issue #7085: Fix crash when importing some extensions in a thread
244 on MacOSX 10.6.
245
Mark Dickinsonb678de82009-11-19 18:41:49 +0000246- Issue #7117: repr(x) for a float x returns a result based on the
247 shortest decimal string that's guaranteed to round back to x under
248 correct rounding (with round-half-to-even rounding mode).
249 Previously it gave a string based on rounding x to 17 decimal digits.
250 repr(x) for a complex number behaves similarly. On platforms where
251 the correctly-rounded strtod and dtoa code is not supported (see below),
252 repr is unchanged.
253
254- Issue #7117: On almost all platforms: float-to-string and
255 string-to-float conversions within Python are now correctly rounded.
256 Places these conversions occur include: str for floats and complex
257 numbers; the float and complex constructors; old-style and new-style
258 numeric formatting; serialization and deserialization of floats and
259 complex numbers using marshal, pickle and json; parsing of float and
260 imaginary literals in Python code; Decimal-to-float conversion.
261
262 The conversions use a Python-adapted version of David Gay's
263 well-known dtoa.c, providing correctly-rounded strtod and dtoa C
264 functions. This code is supported on Windows, and on Unix-like
265 platforms using gcc, icc or suncc as the C compiler. There may be a
266 small number of platforms on which correct operation of this code
267 cannot be guaranteed, so the code is not used: notably, this applies
268 to platforms where the C double format is not IEEE 754 binary64, and
269 to platforms on x86 hardware where the x87 FPU is set to 64-bit
270 precision and Python's configure script is unable to determine how
271 to change the FPU precision. On these platforms conversions use the
272 platform strtod and dtoa, as before.
273
Mark Dickinsonbd15a062009-11-18 19:33:35 +0000274- Issue #7117: Backport round implementation from Python 3.x. round
Mark Dickinsonb678de82009-11-19 18:41:49 +0000275 now uses the correctly-rounded string <-> float conversions
276 described above (when available), and so produces correctly rounded
277 results that will display nicely under the float repr. There are
278 two related small changes: (1) round now accepts any class with an
279 __index__ method for its second argument (but no longer accepts
Mark Dickinsonbd15a062009-11-18 19:33:35 +0000280 floats for the second argument), and (2) an excessively large second
281 integer argument (e.g., round(1.234, 10**100)) no longer raises an
282 exception.
283
Philip Jenveyfab8be22009-11-17 02:42:26 +0000284- Issue #1757126: Fix the cyrillic-asian alias for the ptcp154 encoding.
285
Benjamin Petersone36199b2009-11-12 23:39:44 +0000286- Fix several issues with compile(). The input can now contain Windows and Mac
287 newlines and is no longer required to end in a newline.
288
Mark Dickinsonc04c7c52009-10-26 22:28:14 +0000289- Remove length limitation when constructing a complex number from a
290 unicode string.
291
Raymond Hettingerfa7dadd2009-11-01 20:45:16 +0000292- Issue #7244: itertools.izip_longest() no longer ignores exceptions
293 raised during the formation of an output tuple.
294
Mark Dickinson8d87dc02009-10-25 20:39:06 +0000295- Issue #1087418: Boost performance of bitwise operations for longs.

411 statement and correctly lookup the __enter__ and __exit__ special methods.
412
Mark Dickinsona4e0efa2009-05-20 18:43:07 +0000413- Issue #5829: complex("1e500") no longer raises OverflowError. This
414 makes it consistent with float("1e500") and interpretation of real

Mark Dickinsonb1d45852009-05-11 15:33:08 +0000424- Issue #5981: Fix three minor inf/nan issues in float.fromhex:
425 (1) inf and nan strings with trailing whitespace were incorrectly

427 was locale aware; and (3) the interpretation of fromhex('-nan')
428 didn't match that of float('-nan').
429
Eric Smitha985a3a2009-05-05 18:26:08 +0000430- Issue #5920: For float.__format__, change the behavior with the
431 empty presentation type (that is, not one of 'e', 'f', 'g', or 'n')
432 to be like 'g' but with at least one decimal point and with a
433 default precision of 12. Previously, the behavior the same but with
434 a default precision of 6. This more closely matches str(), and
435 reduces surprises when adding alignment flags to the empty
436 presentation type. This also affects the new complex.__format__ in
437 the same way.
438
R. David Murray7ba8e1c2009-05-04 22:16:24 +0000439- Issue #5890: in subclasses of 'property' the __doc__ attribute was

502 untrackable objects are not tracked by the garbage collector. This can
503 reduce the size of collections and therefore the garbage collection overhead
504 on long-running programs, depending on their particular use of datatypes.
505
Mark Dickinson0b666bf2009-03-23 18:25:13 +0000506- Issue #5512: Rewrite PyLong long division algorithm (x_divrem) to

539 on a 64-bit system.
540
Antoine Pitrou76a4b892009-02-13 13:52:33 +0000541- Issue #5186: Reduce hash collisions for objects with no __hash__ method by

548
Georg Brandl29c6a282009-04-05 20:23:13 +0000549- Issue #1242657: the __len__() and __length_hint__() calls in several tools
Raymond Hettingerb5163702009-02-02 21:50:13 +0000550 were suppressing all exceptions. These include list(), filter(), map(),

Georg Brandl6425a2f2008-12-28 11:54:53 +0000603- Issue #4759: None is now allowed as the first argument of
604 bytearray.translate(). It was always allowed for bytes.translate().
605
Skip Montanarof205c132008-12-23 03:30:15 +0000606- Added test case to ensure attempts to read from a file opened for writing
607 fail.
608
Antoine Pitrou73c0e652008-12-17 22:46:54 +0000609- Issue #2467: gc.DEBUG_STATS reported invalid elapsed times. Also, always
610 print elapsed times, not only when some objects are uncollectable /
611 unreachable. Original patch by Neil Schemenauer.
612
Mark Dickinson1a707982008-12-17 16:14:37 +0000613- Issue #3439: Add a bit_length method to int and long.

616 Original patch by Neal Norwitz.
617
Amaury Forgeot d'Arcad9b5992008-12-10 23:22:49 +0000618- Issue #4597: Fixed exception handling when the __exit__ function of a
619 context manager returns a value that cannot be converted to a bool.
620
Jeffrey Yasskinffd42cf2008-12-10 07:35:02 +0000621- Issue #4597: Fixed several opcodes that weren't always propagating
622 exceptions.
623
Mark Dickinson826f3fe2008-12-05 21:55:28 +0000624- Issue #4445: Replace "sizeof(PyStringObject)" with
625 "offsetof(PyStringObject, ob_sval) + 1" when allocating memory for
626 str instances. On a typical machine this saves 3 bytes of memory
627 (on average) per string allocation.
628
Amaury Forgeot d'Arcdc619012008-11-22 20:01:18 +0000629- Issue #3996: On Windows, the PyOS_CheckStack function would cause the
630 interpreter to abort ("Fatal Python error: Could not reset the stack!")
631 instead of throwing a MemoryError.
632
Raymond Hettinger7989a4d2008-12-03 15:42:10 +0000633- Issue #3689: The list reversed iterator now supports __length_hint__
634 instead of __len__. Behavior now matches other reversed iterators.
635
Benjamin Petersonc078f922008-11-21 22:27:24 +0000636- Issue #4367: Python would segfault during compiling when the unicodedata
637 module couldn't be imported and \N escapes were present.
638
Vinay Sajip213faca2008-12-03 23:22:58 +0000639- Issue #4233: Changed semantic of ``_fileio.FileIO``'s ``close()``
Amaury Forgeot d'Arc32265652008-11-20 23:34:31 +0000640 method on file objects with closefd=False. The file descriptor is still
641 kept open but the file object behaves like a closed file. The ``FileIO``
642 object also got a new readonly attribute ``closefd``.
643
Benjamin Peterson46cc6d12008-11-19 21:49:09 +0000644- Issue #4348: Some bytearray methods returned that didn't cause any change to
645 the bytearray, returned the same bytearray instead of a copy.
646
Amaury Forgeot d'Arc7cfe7ea2008-11-18 22:19:37 +0000647- Issue #4317: Fixed a crash in the imageop.rgb2rgb8() function.
648
Benjamin Peterson273c2332008-11-17 22:39:09 +0000649- Issue #4230: If ``__getattr__`` is a descriptor, it now functions correctly.
650
Benjamin Peterson6624a9f2008-11-03 15:14:51 +0000651- Issue #4048: The parser module now correctly validates relative imports.
652
Benjamin Petersondcee09d2008-10-31 02:16:05 +0000653- Issue #4225: ``from __future__ import unicode_literals`` didn't work in an
654 exec statement.
655
Amaury Forgeot d'Arc69a9c5b2008-10-30 21:18:34 +0000656- Issue #4176: Fixed a crash when pickling an object which ``__reduce__``
657 method does not return iterators for the 4th and 5th items.
658
Benjamin Petersonbdca9422008-10-26 20:21:13 +0000659- Issue #4209: Enabling unicode_literals and the print_function in the same
660 __future__ import didn't work.
661
Benjamin Peterson399b1fe2008-10-25 02:53:28 +0000662- Using ``nonlocal`` as a variable name will now raise a Py3k SyntaxWarning
Georg Brandl7fb00ad2008-10-25 07:00:52 +0000663 because it is a reserved word in 3.x.
Benjamin Peterson399b1fe2008-10-25 02:53:28 +0000664
Hirokazu Yamamoto10a018c2008-10-09 10:00:30 +0000665- On windows, os.chdir given unicode was not working if GetCurrentDirectoryW
666 returned a path longer than MAX_PATH. (But It's doubtful this code path is
667 really executed because I cannot move to such directory on win2k)
668
Amaury Forgeot d'Arcd78b9dc2008-10-07 20:32:10 +0000669- Issue #4069: When set.remove(element) is used with a set element, the element
670 is temporarily replaced with an equivalent frozenset. But the eventual
671 KeyError would always report the empty frozenset([]) as the missing key. Now
672 it correctly refers to the initial element.
673
Antoine Pitrouae5bece2008-12-06 21:29:24 +0000674- Issue #4509: Various issues surrounding resize of bytearray objects to
675 which there are buffer exports.
676
Benjamin Peterson8d5934b2008-12-27 18:24:11 +0000677- Issue #4748: Lambda generators no longer return a value.
678
Kristján Valur Jónsson6220e412009-01-12 09:20:34 +0000679- Issue #3582: Use native TLS functions on Windows
680
Gregory P. Smithae91d092009-03-02 05:13:57 +0000681- The re.sub(), re.subn() and re.split() functions now accept a flags parameter.
682
Matthias Kloseedb5e1e2009-04-04 14:18:13 +0000683- Issue #3845: In PyRun_SimpleFileExFlags avoid invalid memory access with
684 short file names.
685
Matthias Klose91a3b9e2009-04-05 21:19:13 +0000686- Issue #1113244: Py_XINCREF, Py_DECREF, Py_XDECREF: Add `do { ... } while (0)'
687 to avoid compiler warnings.
Matthias Klose0610e082009-04-05 12:43:08 +0000688
Gregory P. Smith2b3eb372009-04-05 23:48:26 +0000689- Issue #5705: os.setuid() would not accept values > 2**31-1 but pwd.getpwnam()
690 returned them on 64bit platforms.
691
Walter Dörwalded960ac2009-05-03 22:36:33 +0000692- Issue #5108: Handle %s like %S and %R in PyUnicode_FromFormatV(): Call
693 PyUnicode_DecodeUTF8() once, remember the result and output it in a second
694 step. This avoids problems with counting UTF-8 bytes that ignores the effect
695 of using the replace error handler in PyUnicode_DecodeUTF8().
696
Walter Dörwald726ba8e2009-05-06 14:32:35 +0000697- Issue #3739: The unicode-internal encoder now reports the number of characters
698 consumed like any other encoder (instead of the number of bytes).
699
Benjamin Peterson91c12eb2009-12-03 02:52:39 +0000700- Issue #2422: When compiled with the ``--with-valgrind`` option, the
701 pymalloc allocator will be automatically disabled when running under
702 Valgrind. This gives improved memory leak detection when running
703 under Valgrind, while taking advantage of pymalloc at other times.

723
Antoine Pitrou30b3b352009-12-02 20:37:54 +0000724- Issue #7333: The `posix` module gains an `initgroups()` function providing
725 access to the initgroups(3) C library call on Unix systems which implement
726 it. Patch by Jean-Paul Calderone.
727
Tarek Ziadéa5076a22009-11-29 22:20:30 +0000728- Issue #7408: Fixed distutils.tests.sdist so it doesn't check for group
729 ownership when the group is not forced, because the group may be different
730 from the user's group and inherit from its container when the test is run.
731
Antoine Pitroud16f57b2009-11-28 15:55:58 +0000732- Issue #1515: Enable use of deepcopy() with instance methods. Patch by

771
Nick Coghlan49868cb2009-11-15 07:30:34 +0000772- Issue #6816: runpy now provides a run_path function that allows Python code
773 to execute file paths that refer to source or compiled Python files as well
774 as zipfiles, directories and other valid sys.path entries that contain a
775 __main__.py file. This allows applications that run other Python scripts to
776 support the same flexibility as the CPython command line itself.
777
Antoine Pitrouc562ca42009-11-13 22:31:18 +0000778- Issue #7318: multiprocessing now uses a timeout when it fails to establish
779 a connection with another process, rather than looping endlessly. The
780 default timeout is 20 seconds, which should be amply sufficient for
781 local connections.

796
Antoine Pitrouaec41242009-11-02 11:34:27 +0000797- Issue #6896: mailbox.Maildir now invalidates its internal cache each time
798 a modification is done through it. This fixes inconsistencies and test
799 failures on systems with slightly bogus mtime behaviour.
800
Gregory P. Smith38f5d8f2009-11-01 18:33:55 +0000801- Issue #7246 & Issue #7208: getpass now properly flushes input before
802 reading from stdin so that existing input does not confuse it and
803 lead to incorrect entry or an IOError. It also properly flushes it
804 afterwards to avoid the terminal echoing the input afterwards on
805 OSes such as Solaris.
806
Mark Dickinson6f390012009-10-29 12:11:18 +0000807- Issue #7233: Fix a number of two-argument Decimal methods to make

809 fix buggy handling of large arguments (those with coefficient longer
810 than the current precision) in shift and rotate.

Martin v. Löwis9fa5a282008-09-11 06:53:30 +00002083- Issue #3642: Suppress warning in obmalloc when size_t is larger than uint.
2084
Amaury Forgeot d'Arc05e34492008-09-10 22:04:45 +00002085- Issue #3743: In a few places, PY_FORMAT_SIZE_T was incorrectly used with
2086 PyString_FromFormat or PyErr_Format to display size_t values. The macro
2087 PY_FORMAT_SIZE_T is designed to select the correct format for the OS
2088 ``printf`` function, whereas PyString_FromFormat has an independent
2089 implementation and uses "%zd" on all platforms for size_t values.
2090 This makes a difference on win64, where ``printf`` needs "%Id" to display
2091 64bit values.

2097 object; previously an int would be returned for small values. the __long__
2098 method is allowed to return either an int or a long, but the behaviour of
2099 float objects should not change to respect backward compatibility.

Amaury Forgeot d'Arc3571fbf2008-09-01 19:52:00 +00002101- Issue #3751: str.rpartition would perform a left-partition when called with
2102 a unicode argument.

Vinay Sajip35e3b032008-09-01 14:33:59 +00002107 PyArg_ParseTuple and friends, which occurred when the argument for "s*"
Antoine Pitroud4ae97b2008-08-29 18:39:48 +00002108 was correctly parsed but parsing of subsequent arguments failed.
2109
Vinay Sajip35e3b032008-09-01 14:33:59 +00002110- Issue #2534: speed up isinstance() and issubclass() by 50-70%, so as to
Antoine Pitrou0668c622008-08-26 22:42:08 +00002111 match Python 2.5 speed despite the __instancecheck__ / __subclasscheck__
2112 mechanism. In the process, fix a bug where isinstance() and issubclass(),
2113 when given a tuple of classes as second argument, were looking up
2114 __instancecheck__ / __subclasscheck__ on the tuple rather than on each
2115 type object.
2116
Neal Norwitz18aa3882008-08-24 05:04:52 +00002117- Fix crashes on memory allocation failure found with failmalloc.

2260-----------------
2261
Guido van Rossumf8402962008-08-20 15:01:50 +00002262- Issue #1878: Remove Py_TPFLAGS_HAVE_VERSION_TAG from
2263 Py_TPFLAGS_DEFAULT when not building the core. This means 3rd party
2264 extensions do not automatically benefit from the class attribute
2265 cache; they will have to explicitly add Py_TPFLAGS_HAVE_VERSION_TAG
2266 to their tp_flags field if they care. This is a backwards
2267 compatibility feature; in 3.0, all types will use the cache by
2268 default.
2269
Benjamin Petersonf647dc12008-08-20 01:27:30 +00002270- Keyword arguments can now follow starred arguments. (``f(a, *args,
2271 keyword=23)`` is now valid syntax.)
2272
Thomas Heller0ad5ae02008-08-19 19:25:04 +00002273- ctypes function pointers that are COM methods have a boolean True

Martin v. Löwisf91d46a2008-08-12 14:49:50 +00002276- Issue #3139: Make buffer-interface thread-safe wrt. PyArg_ParseTuple,
2277 by denying s# to parse objects that have a releasebuffer procedure,
2278 and introducing s*.

Georg Brandl1e13ea92008-08-11 09:07:59 +00002280- Issue #3537: Fix an assertion failure when an empty but presized dict
2281 object was stored in the freelist.
2282
Mark Dickinsonb6467572008-08-04 21:30:09 +00002283- Issue #1481296: Make long(float('nan')) and int(float('nan')) raise
2284 ValueError consistently across platforms.
2285
Amaury Forgeot d'Arc39fd6722008-07-31 21:28:03 +00002286- Issue #3479: On platforms where sizeof(int) is smaller than sizeof(long)
2287 (64bit Unix, for example), unichr() would truncate its argument and return
2288 u'\x00' for unichr(2**32). Now it properly raises an OverflowError.
2289
Neal Norwitze7d8be82008-07-31 17:17:14 +00002290- Apply security patches from Apple.
2291
Amaury Forgeot d'Arc246daed2008-07-31 00:42:16 +00002292- Issue #2542: Now that issubclass() may call arbitrary code, ensure that
2293 PyErr_ExceptionMatches returns 0 when an exception occurs there.
2294
Antoine Pitrou92f82162008-07-25 22:22:08 +00002295- Issue #1819: function calls with several named parameters are now on
2296 average 35% faster (as measured by pybench).
2297
Amaury Forgeot d'Arce4921fe2008-07-21 22:00:38 +00002298- Issue #2378: An unexpected UnboundLocalError or NameError could appear when
2299 the python debugger steps into a class statement: the free variables (local
2300 variables defined in an outer scope) would be deleted from the outer scope.
2301
Gregory P. Smith0470bab2008-07-22 04:46:32 +00002302- Issue #2620: Overflow checking when allocating or reallocating memory
2303 was not always being done properly in some python types and extension
2304 modules. PyMem_MALLOC, PyMem_REALLOC, PyMem_NEW and PyMem_RESIZE have
2305 all been updated to perform better checks and places in the code that
2306 would previously leak memory on the error path when such an allocation
2307 failed have been fixed.

2316
Amaury Forgeot d'Arc351ffb82008-08-18 19:23:47 +00002317- Issue #2234: distutils failed for some versions of the cygwin compiler. The
2318 version reported by these tools does not necessarily follow the python
2319 version numbering scheme, so the module is less strict when parsing it.
2320
Nick Coghlanf70385a2008-08-18 12:42:46 +00002321- Issue #2235: Added Py3k warnings for types which will become unhashable
2322 under the stricter __hash__ inheritance rules in 3.0. Several types
2323 which did not meet the rules for hash invariants and were already
2324 unhashable in 3.0 have now been explicitly flagged as unhashable in
2325 2.6 as well (collections.Mapping, collections.Set, unittest.TestSuite,
2326 xml.dom.minidom.NamedNodeMap, numbers.Number, UserList.UserList)
2327
Brett Cannon88f801d2008-08-18 00:46:22 +00002328- Update __all__ for cookielib, csv, os, urllib2, and weakref to include things

2354 regular expression.
2355
Antoine Pitrou11ec65d2008-08-14 21:04:30 +00002356- Issue #3476: binary buffered reading through the new "io" library is now
2357 thread-safe.
2358
Brett Cannonbf3157b2008-08-14 05:00:03 +00002359- Silence the DeprecationWarning of rfc822 when it is imported by mimetools
2360 since mimetools itself is deprecated. Because modules are cached, all
2361 subsequent imports of rfc822 will not raise a visible DeprecationWarning.
2362
Antoine Pitrou9fcd4b32008-08-11 17:21:36 +00002363- Issue #3134: shutil referenced undefined WindowsError symbol.

2369 version that did not raise a DeprecationWarning under -3.
2370
Antoine Pitrou76b8bee2008-08-09 17:27:23 +00002371- Issue #3205: When iterating over a BZ2File fails allocating memory, raise
2372 a MemoryError rather than silently stop the iteration.
2373
Guido van Rossum59ce9012008-08-09 14:55:34 +00002374- Issue #3487: sre "bytecode" validator. Passing invalid "re-bytecode"
2375 to _sre.compile() will now be rejected. This should not affect anybody
2376 since the re.compile() function never generates invalid re-bytecode.
2377
Skip Montanaroa032bf42008-08-08 22:52:51 +00002378- Issue #3436: Make csv.DictReader's fieldnames attribute a property so that
2379 upon first access it can be automatically initialized from the csv file if
2380 it wasn't initialized during instantiation.
2381
Brett Cannon3aa2a492008-08-06 22:28:09 +00002382- Issue #2338: Create imp.reload() to help with transitioning to Python 3.0 as
2383 the reload() built-in has been removed.
2384
Brett Cannon7e30b672008-08-04 21:52:25 +00002385- Changed code in the following modules/packages to remove warnings raised
Brett Cannonc1b76e42008-08-09 23:06:16 +00002386 while running under the ``-3`` flag: aifc, asynchat, asyncore, bdb, bsddb,

2394 raised an AttributeError.
2395
Benjamin Peterson01a24322008-07-28 23:35:27 +00002396- Issue #2523: Fix quadratic behaviour when read()ing a binary file without
Antoine Pitroude781a42008-08-09 12:43:23 +00002397 asking for a specific length. This problem only affected files opened
2398 using the new "io" module, not the built-in open() function.
Benjamin Peterson01a24322008-07-28 23:35:27 +00002399

2422
Antoine Pitrou5fdfa3e2008-07-25 19:42:26 +00002423- Issue #3394: zipfile.writestr sets external attributes when passed a
2424 file name rather than a ZipInfo instance, so files are extracted with
2425 mode 0600 rather than 000 under Unix.
2426
Gregory P. Smitha36f8fe2008-08-04 00:13:29 +00002427- Issue #1857: subprocess.Popen.poll gained an additional _deadstate keyword
2428 argument in python 2.5, this broke code that subclassed Popen to include its

Nick Coghlan6e8fef02008-08-18 13:14:22 +00002439- Issue #2235: the C API function PyObject_HashNotImplemented and its
2440 interaction with the tp_hash slot (added in 2.6b2) are now documented
2441
Nick Coghlan2a0c2b12008-08-04 12:47:17 +00002442- Issue #643841: The language reference now provides more detailed
2443 coverage of the lookup process for special methods. The disclaimers
2444 regarding lack of coverage of new-style classes have also been
2445 removed, since the coverage is now fairly reasonable.

2449================================
2450
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00002451*Release date: 17-Jul-2008*

Raymond Hettingere3ae6552008-06-20 04:18:15 +00002453Core and Builtins
2454-----------------
2455
Georg Brandl3e483f62008-07-16 22:57:41 +00002456- Issue #3156: Fix inconsistent behavior of the bytearray type: all
2457 its methods now allow for items objects that can be converted to
2458 an integer using operator.index().
2459
Mark Dickinson64b7e502008-07-16 09:40:03 +00002460- Issue #3360: Fix incorrect parsing of '020000000000.0', which
2461 produced a ValueError instead of giving the correct float.
2462
Eric Smitha5fa5a22008-07-16 00:11:49 +00002463- Issue #3083: Add alternate (#) formatting for bin, oct, hex output
2464 for str.format(). This adds the prefix 0b, 0o, or 0x, respectively.
2465
Mark Dickinson7103aa42008-07-15 19:08:33 +00002466- Issue #3008: the float type has a new instance method 'float.hex'
2467 and a new class method 'float.fromhex' to convert floating-point
2468 numbers to and from hexadecimal strings, respectively.
2469
Nick Coghlan6d6bd442008-07-15 15:40:22 +00002470- Issue #2235: __hash__ is once again inherited by default. To allow
2471 collections.Hashable to remain meaningful in the presence of the
2472 default hash implementation (object.__hash__), it is now possible
2473 to explicit block inheritance of hash by setting __hash__=None at
2474 the Python level, or tp_hash=PyObject_HashNotImplemented at the C
2475 level.
2476
Nick Coghlanb028f502008-07-13 14:52:36 +00002477- Issue #3221: Issue a RuntimeWarning instead of raising SystemError if
2478 the parent module cannot be found while performing an absolute import.
2479 This means that an incorrectly defined __package__ attribute will
2480 now only prevent relative imports in that module rather than causing
2481 all imports from that module to fail.
2482
Nick Coghlan14ff9942008-07-08 14:21:42 +00002483- Issue #2517: Allow unicode messages in Exceptions again by correctly
2484 bypassing the instance dictionary when looking up __unicode__ on
2485 new-style classes.
2486
Amaury Forgeot d'Arcbdd941f2008-07-01 20:38:04 +00002487- Issue #3242: Fix a crash inside the print statement, if sys.stdout is
2488 set to a custom object whose write() method happens to install
2489 another file in sys.stdout.
2490
Amaury Forgeot d'Arc1f40c8a2008-06-30 22:42:40 +00002491- Issue #3088: Corrected a race condition in classes derived from
2492 threading.local: the first member set by a thread could be saved in
2493 another thread's dictionary.
2494
Mark Dickinson1ec2fcd2008-06-20 14:53:43 +00002495- Issue #3004: Minor change to slice.indices(): the start and stop
2496 arguments are now treated identically, making the behaviour easier
2497 to describe and understand. For example, slice(None, -10,
2498 1).indices(9) now returns (0, 0, 1) instead of (0, -1, 1), and
2499 slice(None, 10, -1).indices(10) returns (9, 9, -1) instead of (9,
2500 10, -1).
2501
Georg Brandl278fc502008-07-19 12:46:12 +00002502- Issue #3219: Calling a function with repeated keyword arguments,
2503 f(a=2, a=23), would not cause a syntax error. This was a regression
2504 from 2.4 caused by the switch to the new compiler.
Benjamin Peterson175e4d92008-07-01 19:34:52 +00002505
Georg Brandl278fc502008-07-19 12:46:12 +00002506- Issue #2862: Make int and float freelist management consistent with
2507 other freelists. Changes their CompactFreeList apis into
2508 ClearFreeList apis and calls them via gc.collect().
Gregory P. Smith2fe77062008-07-06 03:35:58 +00002509

2511-------
2512
Thomas Heller57adf222008-08-14 19:10:48 +00002513- Issue #3554: ctypes.string_at and ctypes.wstring_at did call Python
2514 api functions without holding the GIL, which could lead to a fatal
2515 error when they failed.
2516
Martin v. Löwisaabf4042008-08-02 07:20:25 +00002517- Issue #799428: Fix Tkinter.Misc._nametowidget to unwrap Tcl command objects.

Jesse Noller13e9d582008-07-16 14:32:36 +00002525- Issue #3125: Remove copy_reg in multiprocessing and replace it with
2526 ForkingPickler.register() to resolve conflict with ctypes.
2527
Vinay Sajip51e65192008-07-18 09:01:10 +00002528- Issue #3090: Fixed ARCHFLAGS parsing on OS/X
Jesse Noller13e9d582008-07-16 14:32:36 +00002529
Thomas Heller880f5292008-07-15 19:39:38 +00002530- Issue #3313: Fixed a crash when a failed dlopen() call does not set
2531 a valid dlerror() message.
2532
Thomas Heller2bad6572008-07-15 17:19:50 +00002533- Issue #3258: Fixed a crash when a ctypes POINTER type to an
2534 incomplete structure was created.
2535
Brett Cannon3d0b9f02008-07-13 01:15:07 +00002536- Issue #3339: dummy_thread.acquire() should not return None.
2537
Raymond Hettingerb01713e2008-07-10 14:34:57 +00002538- Issue #3285: Fractions from_float() and from_decimal() accept Integral arguments.
2539
Andrew M. Kuchlingcc3f2b12008-07-10 14:43:31 +00002540- Issue #3301: Bisect module behaved badly when lo was negative.
Raymond Hettinger3cd1e422008-07-10 14:03:19 +00002541
Amaury Forgeot d'Arc0f7cddc2008-07-06 21:34:39 +00002542- Issue #839496: SimpleHTTPServer used to open text files in text mode. This is
2543 both unnecessary (HTTP allows text content to be sent in several forms) and
Andrew M. Kuchlingcc3f2b12008-07-10 14:43:31 +00002544 wrong because the actual transmitted size could differ from the
Amaury Forgeot d'Arc0f7cddc2008-07-06 21:34:39 +00002545 content-length. The problem had been corrected in the 2.4 branch, but never
2546 merged into trunk.
2547
Georg Brandle78fbcc2008-07-05 10:13:36 +00002548- Issue #2663: add filtering capability to shutil.copytree().

2554- Issue #1746: Correct handling of zipfile archive comments (previously
2555 archives with comments over 4k were flagged as invalid). Allow writing
Vinay Sajip51e65192008-07-18 09:01:10 +00002556 Zip files with archives by setting the 'comment' attribute of a ZipFile.
Martin v. Löwis8c436412008-07-03 12:51:14 +00002557
Vinay Sajip51e65192008-07-18 09:01:10 +00002558- Issue #449227: The rlcompleter module now adds "(" to callable objects

2953 mode or even as a 4-way universal binary (that is, PPC, i386,
Georg Brandl5cc774e2008-06-11 20:28:06 +00002954 PPC64 and x86_64 support in one binary).
Ronald Oussoren5640ce22008-06-05 12:58:24 +00002955
2956 This is controlled by the configure argument ``--with-universal-archs``:
2957
2958 - ``--with-universal-archs=all``: install 4-way universal
2959
2960 - ``--with-universal-archs=32-bit``: install 2-way universal, 32-bit (the default)
2961
2962 - ``--with-universal-archs=64-bit``: install 2-way universal, 64-bit
2963
2964 This option should be used in combination with ``--enable-universalsdk=``.
2965
2966 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 +00003016- Issue #1631171: Re-implement the 'warnings' module in C (the
3017 original Python code has been kept as backup). This will allow for
3018 using the 'warning's machinery in such places as the parser where
3019 use of pure Python code is not possible. Both the ``showarning()``
3020 and ``formatwarning()`` gain an optional 'line' argument which is
3021 not called by default for backwards-compatibility reasons. Setting
3022 ``warnings.showwarning()`` to an implementation that lacks support
3023 for the ``line`` argument will raise a DeprecationWarning.

Georg Brandl3ee81df2008-05-17 18:14:43 +00003086- Issue #2550: The approach used by client/server code for obtaining
3087 ports to listen on in network-oriented tests has been refined in an
3088 effort to facilitate running multiple instances of the entire
3089 regression test suite in parallel without issue.
3090 test_support.bind_port() has been fixed such that it will always
3091 return a unique port -- which wasn't always the case with the
3092 previous implementation, especially if socket options had been set
3093 that affected address reuse (i.e. SO_REUSEADDR, SO_REUSEPORT). The
3094 new implementation of bind_port() will actually raise an exception
3095 if it is passed an AF_INET/SOCK_STREAM socket with either the
3096 SO_REUSEADDR or SO_REUSEPORT socket option set. Furthermore, if
3097 available, bind_port() will set the SO_EXCLUSIVEADDRUSE option on
3098 the socket it's been passed. This currently only applies to
3099 Windows. This option prevents any other sockets from binding to the
3100 host/port we've bound to, thus removing the possibility of the
3101 'non-deterministic' behaviour, as Microsoft puts it, that occurs
3102 when a second SOCK_STREAM socket binds and accepts to a host/port
3103 that's already been bound by another socket. The optional preferred
3104 port parameter to bind_port() has been removed. Under no
3105 circumstances should tests be hard coding ports!
3106
3107 test_support.find_unused_port() has also been introduced, which will
3108 pass a temporary socket object to bind_port() in order to obtain an
3109 unused port. The temporary socket object is then closed and
3110 deleted, and the port is returned. This method should only be used
3111 for obtaining an unused port in order to pass to an external program
3112 (i.e. the -accept [port] argument to openssl's s_server mode) or as
3113 a parameter to a server-oriented class that doesn't give you direct
3114 access to the underlying socket used.
3115
3116 Finally, test_support.HOST has been introduced, which should be used
3117 for the host argument of any relevant socket calls (i.e. bind and
3118 connect).
Trent Nelsone41b0062008-04-08 23:47:30 +00003119

3392Core and builtins
3393-----------------
3394
Fred Drakea8ee94b2008-03-01 02:45:07 +00003395- Issue #2051: pyc and pyo files are no longer created with permission
Barry Warsaw52973612008-03-01 02:23:38 +00003396 644. The mode is now inherited from the py file.
Christian Heimes40346852008-02-23 17:52:07 +00003397
Georg Brandlad61bc82008-02-23 15:11:18 +00003398- Issue #2067: file.__exit__() now calls subclasses' close() method.
3399
3400- Patch #1759: Backport of PEP 3129 class decorators.
Christian Heimes5224d282008-02-23 15:01:05 +00003401
Vinay Sajipb7edfc42008-04-02 21:10:23 +00003402- Issue #1881: An internal parser limit has been increased. Also see
Facundo Batistafc2d0102008-02-23 12:01:13 +00003403 issue 215555 for a discussion.
3404
Eric Smitha73fbe72008-02-23 03:09:44 +00003405- Added the future_builtins module, which contains hex() and oct().
3406 These are the PEP 3127 version of these functions, designed to be
3407 compatible with the hex() and oct() builtins from Python 3.0. They
3408 differ slightly in their output formats from the existing, unchanged
3409 Python 2.6 builtins. The expected usage of the future_builtins
3410 module is:
3411 from future_builtins import hex, oct
3412
Eric Smith7ef40bf2008-02-20 23:34:22 +00003413- Issue #1600: Modifed PyOS_ascii_formatd to use at most 2 digit
3414 exponents for exponents with absolute value < 100. Follows C99
3415 standard. This is a change on Windows, which would use 3 digits.
3416 Also, added 'n' to the formats that PyOS_ascii_formatd understands,
3417 so that any alterations it does to the resulting string will be
3418 available in stringlib/formatter.h (for float.__format__).
3419
Eric Smith5a3c1352008-02-19 13:21:56 +00003420- Implemented PEP 3101, Advanced String Formatting. This adds a new
3421 builtin format(); a format() method for str and unicode; a
3422 __format__() method to object, str, unicode, int, long, float, and
3423 datetime; the class string.Formatter; and the C API
3424 PyObject_Format().
3425
Georg Brandl3ee81df2008-05-17 18:14:43 +00003426- Fixed several potential crashes, all caused by specially crafted
3427 __del__ methods exploiting objects in temporarily inconsistent
3428 state.
Amaury Forgeot d'Arc632fad32008-02-16 20:55:24 +00003429
Vinay Sajipb7edfc42008-04-02 21:10:23 +00003430- Issue #2115: Important speedup in setting __slot__ attributes. Also
Georg Brandl3ee81df2008-05-17 18:14:43 +00003431 prevent a possible crash: an Abstract Base Class would try to access
3432 a slot on a registered virtual subclass.
Amaury Forgeot d'Arc60d6c7f2008-02-15 21:22:45 +00003433
Georg Brandl3ee81df2008-05-17 18:14:43 +00003434- Fixed repr() and str() of complex numbers with infinity or nan as
3435 real or imaginary part.
Christian Heimes2f0da532008-02-15 06:57:08 +00003436
Georg Brandl3ee81df2008-05-17 18:14:43 +00003437- Clear all free lists during a gc.collect() of the highest generation
3438 in order to allow pymalloc to free more arenas. Python may give back
3439 memory to the OS earlier.
Christian Heimes3b718a72008-02-14 12:47:33 +00003440
Georg Brandl3ee81df2008-05-17 18:14:43 +00003441- Issue #2045: Fix an infinite recursion triggered when printing a
3442 subclass of collections.defaultdict, if its default_factory is set
3443 to a bound method.
Amaury Forgeot d'Arcb01aa432008-02-08 00:56:02 +00003444
Christian Heimesf75dbef2008-02-08 00:11:31 +00003445- Fixed a minor memory leak in dictobject.c. The content of the free
3446 list was not freed on interpreter shutdown.
3447
Georg Brandl3ee81df2008-05-17 18:14:43 +00003448- Limit free list of method and builtin function objects to 256
3449 entries each.
Christian Heimes6075a822008-02-06 12:44:34 +00003450
Georg Brandl3ee81df2008-05-17 18:14:43 +00003451- Patch #1953: Added ``sys._compact_freelists()`` and the C API
3452 functions ``PyInt_CompactFreeList`` and ``PyFloat_CompactFreeList``
Christian Heimes422051a2008-02-04 18:00:12 +00003453 to compact the internal free lists of pre-allocted ints and floats.
3454
Georg Brandl3ee81df2008-05-17 18:14:43 +00003455- Issue #1983: Fixed return type of fork(), fork1() and forkpty()
3456 calls. Python expected the return type int but the fork familie
3457 returns pi_t.
Christian Heimes951cc0f2008-01-31 23:08:23 +00003458
Georg Brandl3ee81df2008-05-17 18:14:43 +00003459- Issue #1678380: Fix a bug that identifies 0j and -0j when they
3460 appear in the same code unit.
Mark Dickinson105be772008-01-31 22:17:37 +00003461
Georg Brandl3ee81df2008-05-17 18:14:43 +00003462- Issue #2025: Add tuple.count() and tuple.index() methods to comply
3463 with the collections.Sequence API.
Raymond Hettinger5b07ebc2008-02-07 00:54:20 +00003464
Georg Brandl3ee81df2008-05-17 18:14:43 +00003465- Patch #1970 by Antoine Pitrou: Speedup unicode whitespace and
3466 linebreak detection
Christian Heimes4d4f2702008-01-30 11:32:37 +00003467
Georg Brandl3ee81df2008-05-17 18:14:43 +00003468- Added ``PyType_ClearCache()`` and ``sys._clear_type_cache`` to clear
3469 the internal lookup cache for ref leak tests.
Christian Heimes908caac2008-01-27 23:34:59 +00003470
Georg Brandl3ee81df2008-05-17 18:14:43 +00003471- Patch #1473257: generator objects gain a gi_code attribute. This is
3472 the same object as the func_code attribute of the function that
3473 produced the generator.
Georg Brandl0cdf9a32008-01-26 14:14:20 +00003474
Georg Brandl3ee81df2008-05-17 18:14:43 +00003475- Issue #1920: "while 0" statements were completely removed by the
3476 compiler, even in the presence of an "else" clause, which is
3477 supposed to be run when the condition is false. Now the compiler
3478 correctly emits bytecode for the "else" suite.
Amaury Forgeot d'Arc31eaafe2008-01-24 22:59:25 +00003479
Guido van Rossumeead05f2008-01-24 18:21:02 +00003480- A few crashers fixed: weakref_in_del.py (issue #1377858);
3481 loosing_dict_ref.py (issue #1303614, test67.py);
3482 borrowed_ref_[34].py (not in tracker).
3483
Vinay Sajipd7cf32e2008-01-24 12:43:33 +00003484- Issue #1069410: The "can't load dll" message box on Windows is
Christian Heimesb2302ba2008-01-23 17:15:06 +00003485 suppressed while an extension is loaded by calling SetErrorMode in
3486 dynload_win.c. The error is still reported properly.
3487
Georg Brandl3ee81df2008-05-17 18:14:43 +00003488- Issue #1915: Python compiles with --enable-unicode=no again. However
Christian Heimes082c9b02008-01-23 14:20:50 +00003489 several extension methods and modules do not work without unicode
3490 support.
3491
Georg Brandl26543b12008-01-21 18:36:51 +00003492- Issue #1882: when compiling code from a string, encoding cookies in the
3493 second line of code were not always recognized correctly.
3494
Georg Brandl14404b62008-01-19 19:27:05 +00003495- Issue #1679: "0x" was taken as a valid integer literal.
3496
Georg Brandl6caad7d2008-01-26 14:19:22 +00003497- Issue #1865: ``bytes`` as an alias for ``str`` and b"" as an alias "" were
Christian Heimes288e89a2008-01-18 18:24:07 +00003498 added.
3499
Christian Heimesc94e2b52008-01-14 04:13:37 +00003500- sys.float_info / PyFloat_GetInfo: The floating point information
3501 object was converted from a dict to a specialized structseq object.
3502
Georg Brandl3ee81df2008-05-17 18:14:43 +00003503- Patch #1816: Added sys.flags structseq. It exposes the status of
3504 most command line arguments and PYTHON* environment variables.
Christian Heimesf31b69f2008-01-14 03:42:48 +00003505
Georg Brandl3ee81df2008-05-17 18:14:43 +00003506- Objects/structseq.c: Implemented new structseq representation. The
3507 patch makes structseqs (e.g. the return value of os.stat) more
3508 readable.
Christian Heimes9c201962008-01-14 03:33:52 +00003509
Georg Brandl3ee81df2008-05-17 18:14:43 +00003510- Patch #1700288: added a type attribute cache that caches method
3511 accesses, resulting in speedups in heavily object-oriented code.
Amaury Forgeot d'Arce4c270c2008-01-14 00:29:41 +00003512
Neal Norwitz3fc15b82008-01-10 05:42:58 +00003513- Bug #1776: __import__() no longer accepts filenames on any platform.
3514 The first parameter to __import__() must be a valid module name.
Christian Heimes3403f152008-01-09 19:56:33 +00003515
Georg Brandlaed6c662008-01-07 17:25:53 +00003516- Patch #1668: renamed THREADDEBUG envvar to PYTHONTHREADDEBUG.
3517
Georg Brandl3ee81df2008-05-17 18:14:43 +00003518- Patch #602345: Add -B command line option, PYTHONDONTWRITEBYTECODE
3519 envvar and sys.dont_write_bytecode attribute. All these can be set
3520 to forbid Python to attempt to write compiled bytecode files.
Georg Brandl2da0fce2008-01-07 17:09:35 +00003521
Georg Brandl3ee81df2008-05-17 18:14:43 +00003522- Improve some exception messages when Windows fails to load an
3523 extension module. Now we get for example '%1 is not a valid Win32
3524 application' instead of 'error code 193'.
Amaury Forgeot d'Arce0b76952008-01-04 02:04:15 +00003525
Georg Brandl3ee81df2008-05-17 18:14:43 +00003526- Bug #1481296: Fixed long(float('nan')) != 0L.

Georg Brandl3ee81df2008-05-17 18:14:43 +00003528- Issue #1640: Added math.isinf(x), math.isnan(x) and math.copysign(x,
3529 y) functions.
Christian Heimese2ca4242008-01-03 20:23:15 +00003530
Christian Heimes0a8143f2007-12-18 23:22:54 +00003531- Issue #1635: Platform independent creation and representation of NaN
Georg Brandl3ee81df2008-05-17 18:14:43 +00003532 and INF. float("nan"), float("inf") and float("-inf") now work on
3533 every platform with IEEE 754 semantics.
Christian Heimes0a8143f2007-12-18 23:22:54 +00003534
Georg Brandl3ee81df2008-05-17 18:14:43 +00003535- Compiler now generates simpler and faster code for dictionary
3536 literals. The oparg for BUILD_MAP now indicates an estimated
3537 dictionary size. There is a new opcode, STORE_MAP, for adding
3538 entries to the dictionary.
Raymond Hettingerfd7ed402007-12-18 21:24:09 +00003539
Georg Brandl3ee81df2008-05-17 18:14:43 +00003540- Issue #1638: %zd configure test fails on Linux.

Georg Brandl3ee81df2008-05-17 18:14:43 +00003542- Issue #1620: New property decorator syntax was modifying the
3543 decorator in place instead of creating a new decorator object.
Christian Heimes90e10e72007-12-14 02:35:23 +00003544
Georg Brandl3ee81df2008-05-17 18:14:43 +00003545- Issue #1538: Avoid copying string in split/rsplit if the split char
3546 is not found.
Skip Montanaro26015492007-12-08 15:33:24 +00003547
Andrew M. Kuchling395fe442007-12-05 13:27:20 +00003548- Issue #1553: An erroneous __length_hint__ can make list() raise a
Christian Heimes7cc1c6f2007-12-05 12:52:34 +00003549 SystemError.
3550
Nick Coghlanef01d822007-12-03 12:55:17 +00003551- PEP 366: Allow explicit relative imports when executing modules

3553 __package__ attribute.
3554
Georg Brandl3ee81df2008-05-17 18:14:43 +00003555- Issue #1402: Fix a crash on exit, when another thread is still
3556 running, and if the deallocation of its frames somehow calls the
3557 PyGILState_Ensure() / PyGILState_Release() functions.
Amaury Forgeot d'Arcbe49a902007-11-30 20:37:22 +00003558

3568 file can now be directly executed by passing their name to the
3569 interpreter. The directory/zipfile is automatically inserted as the
3570 first entry in sys.path.
Nick Coghlan327a39b2007-11-18 11:56:28 +00003571
Georg Brandl3ee81df2008-05-17 18:14:43 +00003572- Issue #1265: Fix a problem with sys.settrace, if the tracing
3573 function uses a generator expression when at the same time the
3574 executed code is closing a paused generator.
Amaury Forgeot d'Arc0d75f092007-11-13 21:54:28 +00003575
Raymond Hettinger1760c8a2007-11-08 02:52:43 +00003576- sets and frozensets now have an isdisjoint() method.
3577
Raymond Hettinger3f8caa32007-10-24 01:28:33 +00003578- optimize the performance of builtin.sum().
3579
Neal Norwitz44f326e2007-10-05 05:29:17 +00003580- Fix warnings found by the new version of the Coverity checker.
3581
Georg Brandl3ee81df2008-05-17 18:14:43 +00003582- The enumerate() builtin function is no longer bounded to sequences
3583 smaller than LONG_MAX. Formerly, it raised an OverflowError. Now,
3584 automatically shifts from ints to longs.
Raymond Hettinger8f669372007-10-03 21:18:11 +00003585
Georg Brandl3ee81df2008-05-17 18:14:43 +00003586- Issue #1686386: Tuple's tp_repr did not take into account the
3587 possibility of having a self-referential tuple, which is possible
3588 from C code. Nor did object's tp_str consider that a type's tp_str
3589 could do something that could lead to an inifinite recursion.
3590 Py_ReprEnter() and Py_EnterRecursiveCall(), respectively, fixed the
3591 issues.
Brett Cannon0b14f242007-09-30 19:45:10 +00003592
Georg Brandl3ee81df2008-05-17 18:14:43 +00003593- Issue #1164: It was possible to trigger deadlock when using the
3594 'print' statement to write to a file since the GIL was not released
3595 as needed. Now PyObject_Print() does the right thing along with
3596 various tp_print implementations of the built-in types and those in
3597 the collections module.
Brett Cannon01531592007-09-17 03:28:34 +00003598
Georg Brandl3ee81df2008-05-17 18:14:43 +00003599- Issue #1147: Exceptions were directly allowing string exceptions in
3600 their throw() method even though string exceptions no longer
3601 allowed.
Brett Cannon4c20bc42007-09-11 21:02:28 +00003602
Georg Brandl3ee81df2008-05-17 18:14:43 +00003603- Issue #1096: Prevent a segfault from getting the repr of a very

Brett Cannon1e534b52007-09-07 04:18:30 +00003606- Issue #1202533: Fix infinite recursion calls triggered by calls to
Georg Brandl3ee81df2008-05-17 18:14:43 +00003607 PyObject_Call() never calling back out to Python code to trigger
3608 recursion depth updates/checks. Required the creation of a static
3609 RuntimeError instance in case normalizing an exception put the
3610 recursion check value past its limit. Fixes crashers
3611 infinite_rec_(1|2|4|5).py.
Brett Cannon1e534b52007-09-07 04:18:30 +00003612
Georg Brandl3ee81df2008-05-17 18:14:43 +00003613- Patch #1031213: Decode source line in SyntaxErrors back to its

Georg Brandl3ee81df2008-05-17 18:14:43 +00003627 __*__ attributes. (Some already existed, e.g., __doc__ and
3628 __name__.)
Neal Norwitz0ac60192007-05-27 04:08:54 +00003629
Neal Norwitz8b2bfbc2007-05-23 06:35:32 +00003630- Add -3 option to the interpreter to warn about features that are

Georg Brandl3ee81df2008-05-17 18:14:43 +00003637 "except E as target:". This is to provide forwards compatibility
3638 with Python 3.0.
Collin Winter62903052007-05-18 23:11:24 +00003639
Brett Cannon229cee22007-05-05 01:34:02 +00003640- Deprecate BaseException.message as per PEP 352.

3658
Guido van Rossum143b5642007-03-23 04:58:42 +00003659- Bug #1683368: The object.__init__() and object.__new__() methods are
3660 now stricter in rejecting excess arguments. The only time when
3661 either allows excess arguments is when it is not overridden and the
3662 other one is. For backwards compatibility, when both are
3663 overridden, it is a deprecation warning (for now; maybe a Py3k
Guido van Rossum234b1ff2007-03-23 19:39:01 +00003664 warning later). Also, type.__init__() insists on the same signature
3665 as supported by type.__new__().
Guido van Rossum143b5642007-03-23 04:58:42 +00003666
Georg Brandl3ee81df2008-05-17 18:14:43 +00003667- Patch #1675423: PyComplex_AsCComplex() now tries to convert an
3668 object to complex using its __complex__() method before falling back
3669 to the __float__() method. Therefore, the functions in the cmath
3670 module now can operate on objects that define a __complex__()
3671 method.

3688
Georg Brandl7b9c5552007-03-12 14:30:05 +00003689- Bug #1678647: write a newline after printing an exception in any
3690 case, even when converting the value to a string failed.
3691
Georg Brandl871f1bc2007-03-12 13:17:36 +00003692- The dir() function has been extended to call the __dir__() method on
Georg Brandl3ee81df2008-05-17 18:14:43 +00003693 its argument, if it exists. If not, it will work like before. This
3694 allows customizing the output of dir() in the presence of a
3695 __getattr__().
Georg Brandl871f1bc2007-03-12 13:17:36 +00003696
Collin Winter276887b2007-03-12 16:11:39 +00003697- Patch #922167: Python no longer segfaults when faced with infinitely
3698 self-recursive reload() calls (as reported by bug #742342).
3699

3704 parthensized forms. This means complex(repr(x)) now works instead of
3705 raising a ValueError.
Collin Wintere38051d2007-03-09 20:33:07 +00003706
Georg Brandlaa2321b2007-03-07 00:40:28 +00003707- Patch #703779: unset __file__ in __main__ after running a file. This
Georg Brandl3ee81df2008-05-17 18:14:43 +00003708 makes the filenames the warning module prints much more sensible
3709 when a PYTHONSTARTUP file is used.
Georg Brandlaa2321b2007-03-07 00:40:28 +00003710

Georg Brandl0fca97a2007-03-05 22:28:08 +00003722- Patch #1674228: when assigning a slice (old-style), check for the
3723 sq_ass_slice instead of the sq_slice slot.
3724
Georg Brandl3ee81df2008-05-17 18:14:43 +00003725- When printing an unraisable error, don't print exceptions. before

Georg Brandl3ee81df2008-05-17 18:14:43 +00004351- unittest now verifies more of its assumptions. In particular,
4352 TestCase and TestSuite subclasses (not instances) are no longer
4353 accepted in TestSuite.addTest(). This should cause no
4354 incompatibility since it never made sense with ordinary subclasses
4355 -- the failure just occurred later, with a more cumbersome
4356 exception.

Georg Brandl3ee81df2008-05-17 18:14:43 +00004637- Issue #829951: In the smtplib module, SMTP.starttls() now complies
4638 with RFC 3207 and forgets any knowledge obtained from the server not
4639 obtained from the TLS negotiation itself. Patch contributed by Bill
4640 Fenner.
Gregory P. Smith2b3ba582008-01-17 08:03:17 +00004641
Georg Brandl3ee81df2008-05-17 18:14:43 +00004642- Issue #1339: The smtplib.SMTP class has been refactored a bit such
Gregory P. Smithbde4ae42008-01-17 08:35:49 +00004643 that the SMTP.starttls() caller no longer needs to call ehlo()
4644 beforehand. SMTP.starttls() now raises an exception of the server
Georg Brandl3ee81df2008-05-17 18:14:43 +00004645 does not claim to support starttls. Adds the
4646 SMTP.ehlo_or_helo_if_needed() method. Patch contributed by Bill

4727 complex, tuple, list, dict, set, and frozenset. Formerly, it would
4728 silently miscode subclasses of those types. Now, it raises a

Georg Brandl3ee81df2008-05-17 18:14:43 +00004745 time so that opening a database previously created with the DB_DUP
4746 or DB_DUPSORT flag set will keep the proper behavior on subsequent
4747 opens. Specifically: dictionary assignment to a DB object will
4748 replace all values for a given key when the database allows
4749 duplicate values. DB users should use DB.put(k, v) when they want
4750 to store duplicates; not DB[k] = v.
Gregory P. Smithec10a4a2007-11-05 02:32:26 +00004751

4757 characters with ASCII value less than 32. Also, it correctly quotes
4758 dots only if they occur on a single line, as opposed to the previous
4759 behavior of quoting dots if they are the second character of any
4760 line.
Georg Brandl4aef7272007-03-13 22:49:43 +00004761

Georg Brandl3ee81df2008-05-17 18:14:43 +00005090- ``PySet_Add()`` can now modify a newly created frozenset. Similarly
5091 to ``PyTuple_SetItem``, it can be used to populate a brand new
5092 frozenset; but it does not steal a reference to the added item.
Amaury Forgeot d'Arccab3d982008-02-03 22:51:43 +00005093
Vinay Sajipb7edfc42008-04-02 21:10:23 +00005094- Added ``PySet_Check()`` and ``PyFrozenSet_Check()`` to the set API.

Georg Brandl3ee81df2008-05-17 18:14:43 +00005096- Backport of PyUnicode_FromString(), _FromStringAndSize(), _Format
5097 and _FormatV from Python 3.0. Made PyLong_AsSsize_t and
5098 PyLong_FromSsize_t public functions.
Georg Brandl6caad7d2008-01-26 14:19:22 +00005099
5100- Patch #1720595: add T_BOOL to the range of structmember types.
5101
5102- Issue #1534: Added ``PyFloat_GetMax()``, ``PyFloat_GetMin()`` and
5103 ``PyFloat_GetInfo()`` to the float API.
5104
Georg Brandl3ee81df2008-05-17 18:14:43 +00005105- Issue #1521: On 64bit platforms, using PyArgs_ParseTuple with the t#
5106 of w# format code incorrectly truncated the length to an int, even
5107 when PY_SSIZE_T_CLEAN is set. The str.decode method used to return
5108 incorrect results with huge strings.
Georg Brandl6caad7d2008-01-26 14:19:22 +00005109
Georg Brandl3ee81df2008-05-17 18:14:43 +00005110- Issue #1629: Renamed Py_Size, Py_Type and Py_Refcnt to Py_SIZE,
5111 Py_TYPE and Py_REFCNT.
Georg Brandl6caad7d2008-01-26 14:19:22 +00005112
Georg Brandl3ee81df2008-05-17 18:14:43 +00005113- PEP 3123: Provide forward compatibility with Python 3.0, while
5114 keeping backwards compatibility. Add Py_Refcnt, Py_Type, Py_Size,
5115 and PyVarObject_HEAD_INIT.
Georg Brandl6caad7d2008-01-26 14:19:22 +00005116
Georg Brandl3ee81df2008-05-17 18:14:43 +00005117- Py_ssize_t fields work in structmember when HAVE_LONG_LONG is not
5118 defined.
Georg Brandl6caad7d2008-01-26 14:19:22 +00005119
5120- Patch #1733960: Allow T_LONGLONG to accept ints.
5121
5122- T_PYSSIZET can now be used in PyMemberDef lists for Py_ssize_t members.
5123
Christian Heimes000a0742008-01-03 22:16:32 +00005124- Added a new API function ``PyImport_ImportModuleNoBlock``.
5125
Georg Brandl6caad7d2008-01-26 14:19:22 +00005126- Bug #1637022: Prefix AST symbols with _Py_.
5127
5128- Fix some leftovers from the conversion from int to Py_ssize_t
5129 (relevant to strings and sequences of more than 2**31 items).
5130
5131- Make _PyGILState_NoteThreadState() static, it was not used anywhere
5132 outside of pystate.c and should not be necessary.
5133
Georg Brandl3ee81df2008-05-17 18:14:43 +00005134- ``PyImport_Import`` and ``PyImport_ImportModule`` now always do
5135 absolute imports. In earlier versions they might have used relative
5136 imports under some conditions.
Christian Heimes000a0742008-01-03 22:16:32 +00005137
Georg Brandl3ee81df2008-05-17 18:14:43 +00005138- Added case insensitive comparison methods ``PyOS_stricmp(char*,
5139 char*)`` and ``PyOS_strnicmp(char*, char*, Py_ssize_t)``.
Christian Heimes000a0742008-01-03 22:16:32 +00005140
Georg Brandl3ee81df2008-05-17 18:14:43 +00005141- Bug #1542693: remove semi-colon at end of PyImport_ImportModuleEx
5142 macro so it can be used as an expression.

5147
Georg Brandl3ee81df2008-05-17 18:14:43 +00005148- Patch #1706: Drop support for Win9x, WinME and NT4. Python now
5149 requires Windows 2000 or greater. The _WINVER and NTDDI_VERSION
5150 macros are set to Win2k for x86/32bit builds and WinXP for AMD64
5151 builds.
Christian Heimes95d64472008-02-09 19:55:22 +00005152
Georg Brandl3ee81df2008-05-17 18:14:43 +00005153- Conditionalize definition of _CRT_SECURE_NO_DEPRECATE and
5154 _CRT_NONSTDC_NO_DEPRECATE.

Brett Cannon791d56f2007-05-31 19:40:42 +00005164- buildtools now raises a DeprecationWarning.
5165
Georg Brandl3ee81df2008-05-17 18:14:43 +00005166- Removed the macfs module. It had been deprecated since Python 2.5.
5167 This lead to the deprecation of macostools.touched() as it relied
5168 solely on macfs and was a no-op under OS X.
