57Core and Builtins
58-----------------
59
Benjamin Petersonecdae192010-01-04 00:43:01 +000060- The __complex__ method is now looked up on the class of instances to make it
61 consistent with other special methods.
62
Antoine Pitrou5b7139a2010-01-02 21:12:58 +000063- Issue #7462: Implement the stringlib fast search algorithm for the `rfind`,
64 `rindex`, `rsplit` and `rpartition` methods. Patch by Florent Xicluna.
65
Mark Dickinson1b34d252010-01-01 17:27:30 +000066- Issue #5080: A number of functions and methods previously produced a
67 DeprecationWarning when passed a float argument where an integer was
68 expected. These functions and methods now raise TypeError instead.
69 The majority of the effects of this change are in the extension
70 modules, but some core functions and methods are affected: notably
71 the 'chr', 'range' and 'xrange' builtins, and many unicode/str
72 methods.
73
Benjamin Peterson0f02d392009-12-30 19:34:10 +000074- Issue #7604: Deleting an unset slotted attribute did not raise an
75 AttributeError.
76
Mark Dickinson99d652e2009-12-30 12:12:23 +000077- Issue #7534: Fix handling of IEEE specials (infinities, nans,
78 negative zero) in ** operator. The behaviour now conforms to that
79 described in C99 Annex F.
80
Amaury Forgeot d'Arcc8a2ce72009-12-29 23:06:17 +000081- Issue #7579: the msvcrt module now has docstrings for all its functions.
82
Amaury Forgeot d'Arc8645a5c2009-12-29 22:03:38 +000083- Issue #7413: Passing '\0' as the separator to datetime.datetime.isoformat()
84 used to drop the time part of the result.
85
Mark Dickinson46572832009-12-27 14:55:57 +000086- Issue #1811: improve accuracy and cross-platform consistency for
87 true division of integers: the result of a/b is now correctly
88 rounded for ints a and b (at least on IEEE 754 platforms), and in
89 particular does not depend on the internal representation of a long.
90
Ezio Melottif84caf42009-12-24 22:25:17 +000091- Issue #6108: unicode(exception) and str(exception) should return the same
92 message when only __str__ (and not __unicode__) is overridden in the subclass.
93
Ronald Oussoren92919a62009-12-24 13:30:58 +000094- Issue #6834: replace the implementation for the 'python' and 'pythonw'
95 executables on OSX.
96
97 These executables now work properly with the arch(1) command:
98 ``arch -ppc python`` will start a universal binary version of python
99 in PPC mode (unlike previous releases).
100
R. David Murray0a0a1a82009-12-14 16:28:26 +0000101- Issue #1680159: unicode coercion during an 'in' operation no longer masks
102 the underlying error when the coercion fails for the left hand operand.
103
Benjamin Peterson4895af42009-12-13 16:36:53 +0000104- Issue #7491: Metaclass's __cmp__ method was ignored.

115 by Arfrever.
116
Antoine Pitrou80157252010-01-08 19:20:17 +0000117- Issue #7092: Remove py3k warning when importing cPickle. 2to3 handles
118 renaming of `cPickle` to `pickle`. The warning was annoying since there's
119 no alternative to cPickle if you care about performance. Patch by Florent
120 Xicluna.
121
Antoine Pitrou0d423b82010-01-07 17:46:49 +0000122- Issue #7455: Fix possible crash in cPickle on invalid input. Patch by

129 and make it implement the `io.BufferedIOBase` ABC to allow for further
130 speedups by wrapping it in an `io.BufferedReader`. Patch by Nir Aides.
131
132- Issue #3972: httplib.HTTPConnection now accepts an optional source_address
Gregory P. Smith9d325212010-01-03 02:06:07 +0000133 parameter to allow specifying where your connections come from.

Senthil Kumaran7713acf2009-12-20 06:05:13 +0000151 Patch by Tatsuhiro Tsujikawa.
152
Benjamin Petersonddd392c2009-12-13 19:19:07 +0000153- Issue #7349: Make methods of file objects in the io module accept None as an
154 argument where file-like objects (ie StringIO and BytesIO) accept them to mean
155 the same as passing no argument.
156
Benjamin Petersonc4771d22009-12-13 17:31:31 +0000157- Issue #7348: StringIO.StringIO.readline(-1) now acts as if it got no argument
158 like other file objects.
159
Lars Gustäbel92ca7562009-12-13 11:32:27 +0000160- Issue #7357: tarfile no longer suppresses fatal extraction errors by
161 default.

226-----------------
227
Amaury Forgeot d'Arcd7288712009-12-01 21:51:04 +0000228- Issue #7419: setlocale() could crash the interpreter on Windows when called
229 with invalid values.
230
Eric Smithc4ab8332009-11-29 17:40:57 +0000231- Issue #3382: 'F' formatting for float and complex now convert the
232 result to upper case. This only affects 'inf' and 'nan', since 'f'
233 no longer converts to 'g' for large values.
Amaury Forgeot d'Arcd7288712009-12-01 21:51:04 +0000234
Mark Dickinson9dd5e162009-11-23 20:54:09 +0000235- Remove switch from "%f" formatting to "%g" formatting for floats
236 larger than 1e50 in absolute value.
237
Mark Dickinson18cfada2009-11-23 18:46:41 +0000238- Remove restrictions on precision when formatting floats. E.g.,
239 "%.120g" % 1e-100 used to raise OverflowError, but now gives the
240 requested 120 significant digits instead.
241
Benjamin Peterson89b1a5c2009-11-19 22:58:01 +0000242- Add Py3k warnings for parameter names in parenthesis.
243
Benjamin Peterson48f0a8d2009-11-19 23:19:29 +0000244- Issue #7362: Give a proper error message for def f((x)=3): pass.
Benjamin Peterson89b1a5c2009-11-19 22:58:01 +0000245
Ronald Oussoren315cd0c2009-11-19 16:25:21 +0000246- Issue #7085: Fix crash when importing some extensions in a thread
247 on MacOSX 10.6.
248
Mark Dickinsonb678de82009-11-19 18:41:49 +0000249- Issue #7117: repr(x) for a float x returns a result based on the
250 shortest decimal string that's guaranteed to round back to x under
251 correct rounding (with round-half-to-even rounding mode).
252 Previously it gave a string based on rounding x to 17 decimal digits.
253 repr(x) for a complex number behaves similarly. On platforms where
254 the correctly-rounded strtod and dtoa code is not supported (see below),
255 repr is unchanged.
256
257- Issue #7117: On almost all platforms: float-to-string and
258 string-to-float conversions within Python are now correctly rounded.
259 Places these conversions occur include: str for floats and complex
260 numbers; the float and complex constructors; old-style and new-style
261 numeric formatting; serialization and deserialization of floats and
262 complex numbers using marshal, pickle and json; parsing of float and
263 imaginary literals in Python code; Decimal-to-float conversion.
264
265 The conversions use a Python-adapted version of David Gay's
266 well-known dtoa.c, providing correctly-rounded strtod and dtoa C
267 functions. This code is supported on Windows, and on Unix-like
268 platforms using gcc, icc or suncc as the C compiler. There may be a
269 small number of platforms on which correct operation of this code
270 cannot be guaranteed, so the code is not used: notably, this applies
271 to platforms where the C double format is not IEEE 754 binary64, and
272 to platforms on x86 hardware where the x87 FPU is set to 64-bit
273 precision and Python's configure script is unable to determine how
274 to change the FPU precision. On these platforms conversions use the
275 platform strtod and dtoa, as before.
276
Mark Dickinsonbd15a062009-11-18 19:33:35 +0000277- Issue #7117: Backport round implementation from Python 3.x. round
Mark Dickinsonb678de82009-11-19 18:41:49 +0000278 now uses the correctly-rounded string <-> float conversions
279 described above (when available), and so produces correctly rounded
280 results that will display nicely under the float repr. There are
281 two related small changes: (1) round now accepts any class with an
282 __index__ method for its second argument (but no longer accepts
Mark Dickinsonbd15a062009-11-18 19:33:35 +0000283 floats for the second argument), and (2) an excessively large second
284 integer argument (e.g., round(1.234, 10**100)) no longer raises an
285 exception.
286
Philip Jenveyfab8be22009-11-17 02:42:26 +0000287- Issue #1757126: Fix the cyrillic-asian alias for the ptcp154 encoding.
288
Benjamin Petersone36199b2009-11-12 23:39:44 +0000289- Fix several issues with compile(). The input can now contain Windows and Mac
290 newlines and is no longer required to end in a newline.
291
Mark Dickinsonc04c7c52009-10-26 22:28:14 +0000292- Remove length limitation when constructing a complex number from a
293 unicode string.
294
Raymond Hettingerfa7dadd2009-11-01 20:45:16 +0000295- Issue #7244: itertools.izip_longest() no longer ignores exceptions
296 raised during the formation of an output tuple.
297
Mark Dickinson8d87dc02009-10-25 20:39:06 +0000298- Issue #1087418: Boost performance of bitwise operations for longs.

302 interpreter is killed. Patch by Adam Olsen.
303
Eric Smithc12781a2009-10-19 14:38:14 +0000304- Issue #7168: Document PyFloat_AsString and PyFloat_AsReprString, and

306
Vinay Sajip03d5c342009-10-16 14:06:44 +0000307- Issue #7120: logging: Removed import of multiprocessing which is causing
308 crash in GAE.

415
Mark Dickinsona4e0efa2009-05-20 18:43:07 +0000416- Issue #5829: complex("1e500") no longer raises OverflowError. This

430 was locale aware; and (3) the interpretation of fromhex('-nan')
431 didn't match that of float('-nan').
432
Eric Smitha985a3a2009-05-05 18:26:08 +0000433- Issue #5920: For float.__format__, change the behavior with the
434 empty presentation type (that is, not one of 'e', 'f', 'g', or 'n')
435 to be like 'g' but with at least one decimal point and with a
436 default precision of 12. Previously, the behavior the same but with
437 a default precision of 6. This more closely matches str(), and
438 reduces surprises when adding alignment flags to the empty
439 presentation type. This also affects the new complex.__format__ in
440 the same way.
441
R. David Murray7ba8e1c2009-05-04 22:16:24 +0000442- Issue #5890: in subclasses of 'property' the __doc__ attribute was

506 reduce the size of collections and therefore the garbage collection overhead
507 on long-running programs, depending on their particular use of datatypes.
508
Mark Dickinson0b666bf2009-03-23 18:25:13 +0000509- Issue #5512: Rewrite PyLong long division algorithm (x_divrem) to

542 on a 64-bit system.
543
Antoine Pitrou76a4b892009-02-13 13:52:33 +0000544- Issue #5186: Reduce hash collisions for objects with no __hash__ method by

551
Georg Brandl29c6a282009-04-05 20:23:13 +0000552- Issue #1242657: the __len__() and __length_hint__() calls in several tools
Raymond Hettingerb5163702009-02-02 21:50:13 +0000553 were suppressing all exceptions. These include list(), filter(), map(),

625 exceptions.
626
Mark Dickinson826f3fe2008-12-05 21:55:28 +0000627- Issue #4445: Replace "sizeof(PyStringObject)" with
628 "offsetof(PyStringObject, ob_sval) + 1" when allocating memory for
629 str instances. On a typical machine this saves 3 bytes of memory
630 (on average) per string allocation.
631
Amaury Forgeot d'Arcdc619012008-11-22 20:01:18 +0000632- Issue #3996: On Windows, the PyOS_CheckStack function would cause the
633 interpreter to abort ("Fatal Python error: Could not reset the stack!")
634 instead of throwing a MemoryError.
635
Raymond Hettinger7989a4d2008-12-03 15:42:10 +0000636- Issue #3689: The list reversed iterator now supports __length_hint__

638
Benjamin Petersonc078f922008-11-21 22:27:24 +0000639- Issue #4367: Python would segfault during compiling when the unicodedata

641
Vinay Sajip213faca2008-12-03 23:22:58 +0000642- Issue #4233: Changed semantic of ``_fileio.FileIO``'s ``close()``
Amaury Forgeot d'Arc32265652008-11-20 23:34:31 +0000643 method on file objects with closefd=False. The file descriptor is still
644 kept open but the file object behaves like a closed file. The ``FileIO``
645 object also got a new readonly attribute ``closefd``.
646
Benjamin Peterson46cc6d12008-11-19 21:49:09 +0000647- Issue #4348: Some bytearray methods returned that didn't cause any change to

661
Benjamin Petersonbdca9422008-10-26 20:21:13 +0000662- Issue #4209: Enabling unicode_literals and the print_function in the same
663 __future__ import didn't work.
664
Benjamin Peterson399b1fe2008-10-25 02:53:28 +0000665- Using ``nonlocal`` as a variable name will now raise a Py3k SyntaxWarning
Georg Brandl7fb00ad2008-10-25 07:00:52 +0000666 because it is a reserved word in 3.x.

Hirokazu Yamamoto10a018c2008-10-09 10:00:30 +0000668- On windows, os.chdir given unicode was not working if GetCurrentDirectoryW
669 returned a path longer than MAX_PATH. (But It's doubtful this code path is
670 really executed because I cannot move to such directory on win2k)
671
Amaury Forgeot d'Arcd78b9dc2008-10-07 20:32:10 +0000672- Issue #4069: When set.remove(element) is used with a set element, the element
673 is temporarily replaced with an equivalent frozenset. But the eventual
674 KeyError would always report the empty frozenset([]) as the missing key. Now
675 it correctly refers to the initial element.

693 returned them on 64bit platforms.
694
Walter Dörwalded960ac2009-05-03 22:36:33 +0000695- Issue #5108: Handle %s like %S and %R in PyUnicode_FromFormatV(): Call
696 PyUnicode_DecodeUTF8() once, remember the result and output it in a second
697 step. This avoids problems with counting UTF-8 bytes that ignores the effect
698 of using the replace error handler in PyUnicode_DecodeUTF8().
699
Walter Dörwald726ba8e2009-05-06 14:32:35 +0000700- Issue #3739: The unicode-internal encoder now reports the number of characters
701 consumed like any other encoder (instead of the number of bytes).
702
Benjamin Peterson91c12eb2009-12-03 02:52:39 +0000703- Issue #2422: When compiled with the ``--with-valgrind`` option, the
704 pymalloc allocator will be automatically disabled when running under
705 Valgrind. This gives improved memory leak detection when running
706 under Valgrind, while taking advantage of pymalloc at other times.

Amaury Forgeot d'Arc05e34492008-09-10 22:04:45 +00002088- Issue #3743: In a few places, PY_FORMAT_SIZE_T was incorrectly used with
2089 PyString_FromFormat or PyErr_Format to display size_t values. The macro
2090 PY_FORMAT_SIZE_T is designed to select the correct format for the OS
2091 ``printf`` function, whereas PyString_FromFormat has an independent
2092 implementation and uses "%zd" on all platforms for size_t values.
2093 This makes a difference on win64, where ``printf`` needs "%Id" to display
2094 64bit values.

2100 object; previously an int would be returned for small values. the __long__

Antoine Pitroud4ae97b2008-08-29 18:39:48 +00002111 was correctly parsed but parsing of subsequent arguments failed.
2112
Vinay Sajip35e3b032008-09-01 14:33:59 +00002113- Issue #2534: speed up isinstance() and issubclass() by 50-70%, so as to
Antoine Pitrou0668c622008-08-26 22:42:08 +00002114 match Python 2.5 speed despite the __instancecheck__ / __subclasscheck__
2115 mechanism. In the process, fix a bug where isinstance() and issubclass(),
2116 when given a tuple of classes as second argument, were looking up
2117 __instancecheck__ / __subclasscheck__ on the tuple rather than on each
2118 type object.

Guido van Rossumf8402962008-08-20 15:01:50 +00002265- Issue #1878: Remove Py_TPFLAGS_HAVE_VERSION_TAG from
2266 Py_TPFLAGS_DEFAULT when not building the core. This means 3rd party
2267 extensions do not automatically benefit from the class attribute
2268 cache; they will have to explicitly add Py_TPFLAGS_HAVE_VERSION_TAG
2269 to their tp_flags field if they care. This is a backwards
2270 compatibility feature; in 3.0, all types will use the cache by
2271 default.
2272
Benjamin Petersonf647dc12008-08-20 01:27:30 +00002273- Keyword arguments can now follow starred arguments. (``f(a, *args,
2274 keyword=23)`` is now valid syntax.)
2275
Thomas Heller0ad5ae02008-08-19 19:25:04 +00002276- ctypes function pointers that are COM methods have a boolean True
2277 value again.
2278
Martin v. Löwisf91d46a2008-08-12 14:49:50 +00002279- Issue #3139: Make buffer-interface thread-safe wrt. PyArg_ParseTuple,
2280 by denying s# to parse objects that have a releasebuffer procedure,
2281 and introducing s*.
2282
Georg Brandl1e13ea92008-08-11 09:07:59 +00002283- Issue #3537: Fix an assertion failure when an empty but presized dict
2284 object was stored in the freelist.
2285
Mark Dickinsonb6467572008-08-04 21:30:09 +00002286- Issue #1481296: Make long(float('nan')) and int(float('nan')) raise
2287 ValueError consistently across platforms.
2288
Amaury Forgeot d'Arc39fd6722008-07-31 21:28:03 +00002289- Issue #3479: On platforms where sizeof(int) is smaller than sizeof(long)
2290 (64bit Unix, for example), unichr() would truncate its argument and return
2291 u'\x00' for unichr(2**32). Now it properly raises an OverflowError.
2292
Neal Norwitze7d8be82008-07-31 17:17:14 +00002293- Apply security patches from Apple.
2294
Amaury Forgeot d'Arc246daed2008-07-31 00:42:16 +00002295- Issue #2542: Now that issubclass() may call arbitrary code, ensure that
2296 PyErr_ExceptionMatches returns 0 when an exception occurs there.
2297
Antoine Pitrou92f82162008-07-25 22:22:08 +00002298- Issue #1819: function calls with several named parameters are now on
2299 average 35% faster (as measured by pybench).
2300
Amaury Forgeot d'Arce4921fe2008-07-21 22:00:38 +00002301- Issue #2378: An unexpected UnboundLocalError or NameError could appear when
2302 the python debugger steps into a class statement: the free variables (local
2303 variables defined in an outer scope) would be deleted from the outer scope.
2304
Gregory P. Smith0470bab2008-07-22 04:46:32 +00002305- Issue #2620: Overflow checking when allocating or reallocating memory
2306 was not always being done properly in some python types and extension
2307 modules. PyMem_MALLOC, PyMem_REALLOC, PyMem_NEW and PyMem_RESIZE have
2308 all been updated to perform better checks and places in the code that
2309 would previously leak memory on the error path when such an allocation
2310 failed have been fixed.

2316
Benjamin Petersone977ad42008-08-20 01:42:01 +00002317- The methods ``is_in_tuple()``, ``is_vararg()``, and ``is_keywordarg()`` of
2318 symtable.Symbol have been deprecated for removal in 3.0 and the next release.
2319
Amaury Forgeot d'Arc351ffb82008-08-18 19:23:47 +00002320- Issue #2234: distutils failed for some versions of the cygwin compiler. The
2321 version reported by these tools does not necessarily follow the python
2322 version numbering scheme, so the module is less strict when parsing it.
2323
Nick Coghlanf70385a2008-08-18 12:42:46 +00002324- Issue #2235: Added Py3k warnings for types which will become unhashable
2325 under the stricter __hash__ inheritance rules in 3.0. Several types
2326 which did not meet the rules for hash invariants and were already
2327 unhashable in 3.0 have now been explicitly flagged as unhashable in
2328 2.6 as well (collections.Mapping, collections.Set, unittest.TestSuite,
2329 xml.dom.minidom.NamedNodeMap, numbers.Number, UserList.UserList)
2330
Brett Cannon88f801d2008-08-18 00:46:22 +00002331- Update __all__ for cookielib, csv, os, urllib2, and weakref to include things
2332 imported into the module but exposed as part of the module's API.
2333
Brett Cannon7b96f072008-08-18 00:41:11 +00002334- Remove an unneeded import of abc.ABCMeta from 'inspect'.

2339
Hirokazu Yamamoto41a81eb2008-08-17 13:10:46 +00002340- Issue #3575: Incremental decoder's decode function now takes bytearray
2341 by using 's*' instead of 't#'.
2342
Mark Dickinson3e4caeb2009-02-21 20:27:01 +00002343- Issue #2222: Fixed reference leak when occurred os.rename()
Hirokazu Yamamoto7f30a682008-08-17 09:46:56 +00002344 fails unicode conversion on 2nd parameter. (windows only)
2345
Facundo Batista94f243a2008-08-17 03:38:39 +00002346- Issue 2464. urllib2 now supports a malformation in the URL received
2347 in a redirect.

Brett Cannon721b1452008-08-16 22:00:27 +00002350 BaseHTTPServer, cgi (and rfc822), httplib.
Brett Cannonabe423e2008-08-16 21:47:07 +00002351
Facundo Batistaeb90b782008-08-16 14:44:07 +00002352- Issue #2776: fixed small issue when handling an URL with double slash
2353 after a 302 response in the case of not going through a proxy.
2354
Antoine Pitroub90a8be2008-08-15 21:03:21 +00002355- Issue #2676: in the email package, content-type parsing was hanging on
2356 pathological input because of quadratic or exponential behaviour of a
2357 regular expression.
2358
Antoine Pitrou11ec65d2008-08-14 21:04:30 +00002359- Issue #3476: binary buffered reading through the new "io" library is now
2360 thread-safe.
2361
Brett Cannonbf3157b2008-08-14 05:00:03 +00002362- Silence the DeprecationWarning of rfc822 when it is imported by mimetools
2363 since mimetools itself is deprecated. Because modules are cached, all
2364 subsequent imports of rfc822 will not raise a visible DeprecationWarning.
2365
Antoine Pitrou9fcd4b32008-08-11 17:21:36 +00002366- Issue #3134: shutil referenced undefined WindowsError symbol.
2367
Robert Schuppenies14646332008-08-10 11:01:53 +00002368- Issue #1342811: Fix leak in Tkinter.Menu.delete. Commands associated to
2369 menu entries were not deleted.
2370
Brett Cannon83e81842008-08-09 23:30:55 +00002371- Copied the implementation of reduce() to _functools.reduce() to have a
2372 version that did not raise a DeprecationWarning under -3.
2373
Antoine Pitrou76b8bee2008-08-09 17:27:23 +00002374- Issue #3205: When iterating over a BZ2File fails allocating memory, raise
2375 a MemoryError rather than silently stop the iteration.
2376
Guido van Rossum59ce9012008-08-09 14:55:34 +00002377- Issue #3487: sre "bytecode" validator. Passing invalid "re-bytecode"
2378 to _sre.compile() will now be rejected. This should not affect anybody
2379 since the re.compile() function never generates invalid re-bytecode.
2380
Skip Montanaroa032bf42008-08-08 22:52:51 +00002381- Issue #3436: Make csv.DictReader's fieldnames attribute a property so that
2382 upon first access it can be automatically initialized from the csv file if
2383 it wasn't initialized during instantiation.
2384
Brett Cannon3aa2a492008-08-06 22:28:09 +00002385- Issue #2338: Create imp.reload() to help with transitioning to Python 3.0 as
2386 the reload() built-in has been removed.
2387
Brett Cannon7e30b672008-08-04 21:52:25 +00002388- Changed code in the following modules/packages to remove warnings raised
Brett Cannonc1b76e42008-08-09 23:06:16 +00002389 while running under the ``-3`` flag: aifc, asynchat, asyncore, bdb, bsddb,

2397 raised an AttributeError.
2398
Benjamin Peterson01a24322008-07-28 23:35:27 +00002399- Issue #2523: Fix quadratic behaviour when read()ing a binary file without
Antoine Pitroude781a42008-08-09 12:43:23 +00002400 asking for a specific length. This problem only affected files opened
2401 using the new "io" module, not the built-in open() function.
Benjamin Peterson01a24322008-07-28 23:35:27 +00002402
Mark Dickinsonfe84cce2008-07-27 06:39:07 +00002403- Issue #3449: Update decimal module to use most recent specification
2404 (v. 1.68) and tests (v. 2.58) from IBM.
2405

2425
Antoine Pitrou5fdfa3e2008-07-25 19:42:26 +00002426- Issue #3394: zipfile.writestr sets external attributes when passed a
2427 file name rather than a ZipInfo instance, so files are extracted with
2428 mode 0600 rather than 000 under Unix.
2429
Gregory P. Smitha36f8fe2008-08-04 00:13:29 +00002430- Issue #1857: subprocess.Popen.poll gained an additional _deadstate keyword
2431 argument in python 2.5, this broke code that subclassed Popen to include its
2432 own poll method. Fixed my moving _deadstate to an _internal_poll method.

2440-------------
2441
Nick Coghlan6e8fef02008-08-18 13:14:22 +00002442- Issue #2235: the C API function PyObject_HashNotImplemented and its
2443 interaction with the tp_hash slot (added in 2.6b2) are now documented
2444
Nick Coghlan2a0c2b12008-08-04 12:47:17 +00002445- Issue #643841: The language reference now provides more detailed
2446 coverage of the lookup process for special methods. The disclaimers
2447 regarding lack of coverage of new-style classes have also been
2448 removed, since the coverage is now fairly reasonable.

2452================================
2453
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00002454*Release date: 17-Jul-2008*
2455
Raymond Hettingere3ae6552008-06-20 04:18:15 +00002456Core and Builtins
2457-----------------
2458
Georg Brandl3e483f62008-07-16 22:57:41 +00002459- Issue #3156: Fix inconsistent behavior of the bytearray type: all
2460 its methods now allow for items objects that can be converted to
2461 an integer using operator.index().
2462
Mark Dickinson64b7e502008-07-16 09:40:03 +00002463- Issue #3360: Fix incorrect parsing of '020000000000.0', which
2464 produced a ValueError instead of giving the correct float.
2465
Eric Smitha5fa5a22008-07-16 00:11:49 +00002466- Issue #3083: Add alternate (#) formatting for bin, oct, hex output
2467 for str.format(). This adds the prefix 0b, 0o, or 0x, respectively.
2468
Mark Dickinson7103aa42008-07-15 19:08:33 +00002469- Issue #3008: the float type has a new instance method 'float.hex'
2470 and a new class method 'float.fromhex' to convert floating-point
2471 numbers to and from hexadecimal strings, respectively.
2472
Nick Coghlan6d6bd442008-07-15 15:40:22 +00002473- Issue #2235: __hash__ is once again inherited by default. To allow
2474 collections.Hashable to remain meaningful in the presence of the
2475 default hash implementation (object.__hash__), it is now possible
2476 to explicit block inheritance of hash by setting __hash__=None at
2477 the Python level, or tp_hash=PyObject_HashNotImplemented at the C
2478 level.
2479
Nick Coghlanb028f502008-07-13 14:52:36 +00002480- Issue #3221: Issue a RuntimeWarning instead of raising SystemError if
2481 the parent module cannot be found while performing an absolute import.
2482 This means that an incorrectly defined __package__ attribute will
2483 now only prevent relative imports in that module rather than causing
2484 all imports from that module to fail.
2485
Nick Coghlan14ff9942008-07-08 14:21:42 +00002486- Issue #2517: Allow unicode messages in Exceptions again by correctly
2487 bypassing the instance dictionary when looking up __unicode__ on
2488 new-style classes.
2489
Amaury Forgeot d'Arcbdd941f2008-07-01 20:38:04 +00002490- Issue #3242: Fix a crash inside the print statement, if sys.stdout is
2491 set to a custom object whose write() method happens to install
2492 another file in sys.stdout.
2493
Amaury Forgeot d'Arc1f40c8a2008-06-30 22:42:40 +00002494- Issue #3088: Corrected a race condition in classes derived from
2495 threading.local: the first member set by a thread could be saved in
2496 another thread's dictionary.
2497
Mark Dickinson1ec2fcd2008-06-20 14:53:43 +00002498- Issue #3004: Minor change to slice.indices(): the start and stop
2499 arguments are now treated identically, making the behaviour easier
2500 to describe and understand. For example, slice(None, -10,
2501 1).indices(9) now returns (0, 0, 1) instead of (0, -1, 1), and
2502 slice(None, 10, -1).indices(10) returns (9, 9, -1) instead of (9,
2503 10, -1).
2504
Georg Brandl278fc502008-07-19 12:46:12 +00002505- Issue #3219: Calling a function with repeated keyword arguments,
2506 f(a=2, a=23), would not cause a syntax error. This was a regression
2507 from 2.4 caused by the switch to the new compiler.
Benjamin Peterson175e4d92008-07-01 19:34:52 +00002508
Georg Brandl278fc502008-07-19 12:46:12 +00002509- Issue #2862: Make int and float freelist management consistent with
2510 other freelists. Changes their CompactFreeList apis into
2511 ClearFreeList apis and calls them via gc.collect().
Gregory P. Smith2fe77062008-07-06 03:35:58 +00002512

2514-------
2515
Thomas Heller57adf222008-08-14 19:10:48 +00002516- Issue #3554: ctypes.string_at and ctypes.wstring_at did call Python
2517 api functions without holding the GIL, which could lead to a fatal
2518 error when they failed.
2519
Martin v. Löwisaabf4042008-08-02 07:20:25 +00002520- Issue #799428: Fix Tkinter.Misc._nametowidget to unwrap Tcl command objects.

Jesse Noller13e9d582008-07-16 14:32:36 +00002528- Issue #3125: Remove copy_reg in multiprocessing and replace it with
2529 ForkingPickler.register() to resolve conflict with ctypes.
2530
Vinay Sajip51e65192008-07-18 09:01:10 +00002531- Issue #3090: Fixed ARCHFLAGS parsing on OS/X
Jesse Noller13e9d582008-07-16 14:32:36 +00002532
Thomas Heller880f5292008-07-15 19:39:38 +00002533- Issue #3313: Fixed a crash when a failed dlopen() call does not set
2534 a valid dlerror() message.
2535
Thomas Heller2bad6572008-07-15 17:19:50 +00002536- Issue #3258: Fixed a crash when a ctypes POINTER type to an
2537 incomplete structure was created.
2538
Brett Cannon3d0b9f02008-07-13 01:15:07 +00002539- Issue #3339: dummy_thread.acquire() should not return None.
2540
Raymond Hettingerb01713e2008-07-10 14:34:57 +00002541- Issue #3285: Fractions from_float() and from_decimal() accept Integral arguments.
2542
Andrew M. Kuchlingcc3f2b12008-07-10 14:43:31 +00002543- Issue #3301: Bisect module behaved badly when lo was negative.
Raymond Hettinger3cd1e422008-07-10 14:03:19 +00002544
Amaury Forgeot d'Arc0f7cddc2008-07-06 21:34:39 +00002545- Issue #839496: SimpleHTTPServer used to open text files in text mode. This is
2546 both unnecessary (HTTP allows text content to be sent in several forms) and
Andrew M. Kuchlingcc3f2b12008-07-10 14:43:31 +00002547 wrong because the actual transmitted size could differ from the
Amaury Forgeot d'Arc0f7cddc2008-07-06 21:34:39 +00002548 content-length. The problem had been corrected in the 2.4 branch, but never
2549 merged into trunk.
2550
Georg Brandle78fbcc2008-07-05 10:13:36 +00002551- Issue #2663: add filtering capability to shutil.copytree().

2554
2555- Issue #1526: Allow more than 64k files to be added to Zip64 file.
2556
2557- Issue #1746: Correct handling of zipfile archive comments (previously

2956 mode or even as a 4-way universal binary (that is, PPC, i386,
Georg Brandl5cc774e2008-06-11 20:28:06 +00002957 PPC64 and x86_64 support in one binary).
Ronald Oussoren5640ce22008-06-05 12:58:24 +00002958
2959 This is controlled by the configure argument ``--with-universal-archs``:
2960
2961 - ``--with-universal-archs=all``: install 4-way universal
2962
2963 - ``--with-universal-archs=32-bit``: install 2-way universal, 32-bit (the default)
2964
2965 - ``--with-universal-archs=64-bit``: install 2-way universal, 64-bit
2966
2967 This option should be used in combination with ``--enable-universalsdk=``.
2968
2969 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 +00003019- Issue #1631171: Re-implement the 'warnings' module in C (the
3020 original Python code has been kept as backup). This will allow for
3021 using the 'warning's machinery in such places as the parser where
3022 use of pure Python code is not possible. Both the ``showarning()``
3023 and ``formatwarning()`` gain an optional 'line' argument which is
3024 not called by default for backwards-compatibility reasons. Setting
3025 ``warnings.showwarning()`` to an implementation that lacks support
3026 for the ``line`` argument will raise a DeprecationWarning.

3050
Gregory P. Smithd59fefb2008-04-22 08:11:33 +00003051- The getpass module has been improved on Unix. It now uses /dev/tty
3052 by default and uses stderr instead of stdout. A GetPassWarning is
3053 issued when input echo cannot be controlled.

Georg Brandl3ee81df2008-05-17 18:14:43 +00003089- Issue #2550: The approach used by client/server code for obtaining
3090 ports to listen on in network-oriented tests has been refined in an
3091 effort to facilitate running multiple instances of the entire
3092 regression test suite in parallel without issue.
3093 test_support.bind_port() has been fixed such that it will always
3094 return a unique port -- which wasn't always the case with the
3095 previous implementation, especially if socket options had been set
3096 that affected address reuse (i.e. SO_REUSEADDR, SO_REUSEPORT). The
3097 new implementation of bind_port() will actually raise an exception
3098 if it is passed an AF_INET/SOCK_STREAM socket with either the
3099 SO_REUSEADDR or SO_REUSEPORT socket option set. Furthermore, if
3100 available, bind_port() will set the SO_EXCLUSIVEADDRUSE option on
3101 the socket it's been passed. This currently only applies to
3102 Windows. This option prevents any other sockets from binding to the
3103 host/port we've bound to, thus removing the possibility of the
3104 'non-deterministic' behaviour, as Microsoft puts it, that occurs
3105 when a second SOCK_STREAM socket binds and accepts to a host/port
3106 that's already been bound by another socket. The optional preferred
3107 port parameter to bind_port() has been removed. Under no
3108 circumstances should tests be hard coding ports!
3109
3110 test_support.find_unused_port() has also been introduced, which will
3111 pass a temporary socket object to bind_port() in order to obtain an
3112 unused port. The temporary socket object is then closed and
3113 deleted, and the port is returned. This method should only be used
3114 for obtaining an unused port in order to pass to an external program
3115 (i.e. the -accept [port] argument to openssl's s_server mode) or as
3116 a parameter to a server-oriented class that doesn't give you direct
3117 access to the underlying socket used.
3118
3119 Finally, test_support.HOST has been introduced, which should be used
3120 for the host argument of any relevant socket calls (i.e. bind and

3395Core and builtins
3396-----------------
3397
Fred Drakea8ee94b2008-03-01 02:45:07 +00003398- Issue #2051: pyc and pyo files are no longer created with permission
Barry Warsaw52973612008-03-01 02:23:38 +00003399 644. The mode is now inherited from the py file.
Christian Heimes40346852008-02-23 17:52:07 +00003400
Georg Brandlad61bc82008-02-23 15:11:18 +00003401- Issue #2067: file.__exit__() now calls subclasses' close() method.
3402
3403- Patch #1759: Backport of PEP 3129 class decorators.
Christian Heimes5224d282008-02-23 15:01:05 +00003404
Vinay Sajipb7edfc42008-04-02 21:10:23 +00003405- Issue #1881: An internal parser limit has been increased. Also see
Facundo Batistafc2d0102008-02-23 12:01:13 +00003406 issue 215555 for a discussion.
3407
Eric Smitha73fbe72008-02-23 03:09:44 +00003408- Added the future_builtins module, which contains hex() and oct().
3409 These are the PEP 3127 version of these functions, designed to be
3410 compatible with the hex() and oct() builtins from Python 3.0. They
3411 differ slightly in their output formats from the existing, unchanged
3412 Python 2.6 builtins. The expected usage of the future_builtins
3413 module is:
3414 from future_builtins import hex, oct
3415
Eric Smith7ef40bf2008-02-20 23:34:22 +00003416- Issue #1600: Modifed PyOS_ascii_formatd to use at most 2 digit
3417 exponents for exponents with absolute value < 100. Follows C99
3418 standard. This is a change on Windows, which would use 3 digits.
3419 Also, added 'n' to the formats that PyOS_ascii_formatd understands,
3420 so that any alterations it does to the resulting string will be
3421 available in stringlib/formatter.h (for float.__format__).
3422
Eric Smith5a3c1352008-02-19 13:21:56 +00003423- Implemented PEP 3101, Advanced String Formatting. This adds a new
3424 builtin format(); a format() method for str and unicode; a
3425 __format__() method to object, str, unicode, int, long, float, and
3426 datetime; the class string.Formatter; and the C API
3427 PyObject_Format().
3428
Georg Brandl3ee81df2008-05-17 18:14:43 +00003429- Fixed several potential crashes, all caused by specially crafted
3430 __del__ methods exploiting objects in temporarily inconsistent
3431 state.
Amaury Forgeot d'Arc632fad32008-02-16 20:55:24 +00003432
Vinay Sajipb7edfc42008-04-02 21:10:23 +00003433- Issue #2115: Important speedup in setting __slot__ attributes. Also
Georg Brandl3ee81df2008-05-17 18:14:43 +00003434 prevent a possible crash: an Abstract Base Class would try to access
3435 a slot on a registered virtual subclass.
Amaury Forgeot d'Arc60d6c7f2008-02-15 21:22:45 +00003436
Georg Brandl3ee81df2008-05-17 18:14:43 +00003437- Fixed repr() and str() of complex numbers with infinity or nan as
3438 real or imaginary part.
Christian Heimes2f0da532008-02-15 06:57:08 +00003439
Georg Brandl3ee81df2008-05-17 18:14:43 +00003440- Clear all free lists during a gc.collect() of the highest generation
3441 in order to allow pymalloc to free more arenas. Python may give back
3442 memory to the OS earlier.
Christian Heimes3b718a72008-02-14 12:47:33 +00003443
Georg Brandl3ee81df2008-05-17 18:14:43 +00003444- Issue #2045: Fix an infinite recursion triggered when printing a
3445 subclass of collections.defaultdict, if its default_factory is set
3446 to a bound method.
Amaury Forgeot d'Arcb01aa432008-02-08 00:56:02 +00003447
Christian Heimesf75dbef2008-02-08 00:11:31 +00003448- Fixed a minor memory leak in dictobject.c. The content of the free
3449 list was not freed on interpreter shutdown.
3450
Georg Brandl3ee81df2008-05-17 18:14:43 +00003451- Limit free list of method and builtin function objects to 256
3452 entries each.
Christian Heimes6075a822008-02-06 12:44:34 +00003453
Georg Brandl3ee81df2008-05-17 18:14:43 +00003454- Patch #1953: Added ``sys._compact_freelists()`` and the C API
3455 functions ``PyInt_CompactFreeList`` and ``PyFloat_CompactFreeList``
Christian Heimes422051a2008-02-04 18:00:12 +00003456 to compact the internal free lists of pre-allocted ints and floats.
3457
Georg Brandl3ee81df2008-05-17 18:14:43 +00003458- Issue #1983: Fixed return type of fork(), fork1() and forkpty()
3459 calls. Python expected the return type int but the fork familie
3460 returns pi_t.
Christian Heimes951cc0f2008-01-31 23:08:23 +00003461
Georg Brandl3ee81df2008-05-17 18:14:43 +00003462- Issue #1678380: Fix a bug that identifies 0j and -0j when they
3463 appear in the same code unit.
Mark Dickinson105be772008-01-31 22:17:37 +00003464
Georg Brandl3ee81df2008-05-17 18:14:43 +00003465- Issue #2025: Add tuple.count() and tuple.index() methods to comply
3466 with the collections.Sequence API.
Raymond Hettinger5b07ebc2008-02-07 00:54:20 +00003467
Georg Brandl3ee81df2008-05-17 18:14:43 +00003468- Patch #1970 by Antoine Pitrou: Speedup unicode whitespace and
3469 linebreak detection
Christian Heimes4d4f2702008-01-30 11:32:37 +00003470
Georg Brandl3ee81df2008-05-17 18:14:43 +00003471- Added ``PyType_ClearCache()`` and ``sys._clear_type_cache`` to clear
3472 the internal lookup cache for ref leak tests.
Christian Heimes908caac2008-01-27 23:34:59 +00003473
Georg Brandl3ee81df2008-05-17 18:14:43 +00003474- Patch #1473257: generator objects gain a gi_code attribute. This is
3475 the same object as the func_code attribute of the function that
3476 produced the generator.
Georg Brandl0cdf9a32008-01-26 14:14:20 +00003477
Georg Brandl3ee81df2008-05-17 18:14:43 +00003478- Issue #1920: "while 0" statements were completely removed by the
3479 compiler, even in the presence of an "else" clause, which is
3480 supposed to be run when the condition is false. Now the compiler
3481 correctly emits bytecode for the "else" suite.
Amaury Forgeot d'Arc31eaafe2008-01-24 22:59:25 +00003482
Guido van Rossumeead05f2008-01-24 18:21:02 +00003483- A few crashers fixed: weakref_in_del.py (issue #1377858);
3484 loosing_dict_ref.py (issue #1303614, test67.py);
3485 borrowed_ref_[34].py (not in tracker).
3486
Vinay Sajipd7cf32e2008-01-24 12:43:33 +00003487- Issue #1069410: The "can't load dll" message box on Windows is
Christian Heimesb2302ba2008-01-23 17:15:06 +00003488 suppressed while an extension is loaded by calling SetErrorMode in
3489 dynload_win.c. The error is still reported properly.
3490
Georg Brandl3ee81df2008-05-17 18:14:43 +00003491- Issue #1915: Python compiles with --enable-unicode=no again. However
Christian Heimes082c9b02008-01-23 14:20:50 +00003492 several extension methods and modules do not work without unicode
3493 support.
3494
Georg Brandl26543b12008-01-21 18:36:51 +00003495- Issue #1882: when compiling code from a string, encoding cookies in the
3496 second line of code were not always recognized correctly.
3497
Georg Brandl14404b62008-01-19 19:27:05 +00003498- Issue #1679: "0x" was taken as a valid integer literal.
3499
Georg Brandl6caad7d2008-01-26 14:19:22 +00003500- Issue #1865: ``bytes`` as an alias for ``str`` and b"" as an alias "" were
Christian Heimes288e89a2008-01-18 18:24:07 +00003501 added.
3502
Christian Heimesc94e2b52008-01-14 04:13:37 +00003503- sys.float_info / PyFloat_GetInfo: The floating point information
3504 object was converted from a dict to a specialized structseq object.
3505
Georg Brandl3ee81df2008-05-17 18:14:43 +00003506- Patch #1816: Added sys.flags structseq. It exposes the status of
3507 most command line arguments and PYTHON* environment variables.
Christian Heimesf31b69f2008-01-14 03:42:48 +00003508
Georg Brandl3ee81df2008-05-17 18:14:43 +00003509- Objects/structseq.c: Implemented new structseq representation. The
3510 patch makes structseqs (e.g. the return value of os.stat) more
3511 readable.
Christian Heimes9c201962008-01-14 03:33:52 +00003512
Georg Brandl3ee81df2008-05-17 18:14:43 +00003513- Patch #1700288: added a type attribute cache that caches method
3514 accesses, resulting in speedups in heavily object-oriented code.
Amaury Forgeot d'Arce4c270c2008-01-14 00:29:41 +00003515
Neal Norwitz3fc15b82008-01-10 05:42:58 +00003516- Bug #1776: __import__() no longer accepts filenames on any platform.
3517 The first parameter to __import__() must be a valid module name.
Christian Heimes3403f152008-01-09 19:56:33 +00003518
Georg Brandlaed6c662008-01-07 17:25:53 +00003519- Patch #1668: renamed THREADDEBUG envvar to PYTHONTHREADDEBUG.
3520
Georg Brandl3ee81df2008-05-17 18:14:43 +00003521- Patch #602345: Add -B command line option, PYTHONDONTWRITEBYTECODE
3522 envvar and sys.dont_write_bytecode attribute. All these can be set
3523 to forbid Python to attempt to write compiled bytecode files.
Georg Brandl2da0fce2008-01-07 17:09:35 +00003524
Georg Brandl3ee81df2008-05-17 18:14:43 +00003525- Improve some exception messages when Windows fails to load an
3526 extension module. Now we get for example '%1 is not a valid Win32
3527 application' instead of 'error code 193'.
Amaury Forgeot d'Arce0b76952008-01-04 02:04:15 +00003528
Georg Brandl3ee81df2008-05-17 18:14:43 +00003529- Bug #1481296: Fixed long(float('nan')) != 0L.

Georg Brandl3ee81df2008-05-17 18:14:43 +00003531- Issue #1640: Added math.isinf(x), math.isnan(x) and math.copysign(x,
3532 y) functions.
Christian Heimese2ca4242008-01-03 20:23:15 +00003533
Christian Heimes0a8143f2007-12-18 23:22:54 +00003534- Issue #1635: Platform independent creation and representation of NaN
Georg Brandl3ee81df2008-05-17 18:14:43 +00003535 and INF. float("nan"), float("inf") and float("-inf") now work on
3536 every platform with IEEE 754 semantics.
Christian Heimes0a8143f2007-12-18 23:22:54 +00003537
Georg Brandl3ee81df2008-05-17 18:14:43 +00003538- Compiler now generates simpler and faster code for dictionary
3539 literals. The oparg for BUILD_MAP now indicates an estimated
3540 dictionary size. There is a new opcode, STORE_MAP, for adding
3541 entries to the dictionary.

Georg Brandl3ee81df2008-05-17 18:14:43 +00003575- Issue #1265: Fix a problem with sys.settrace, if the tracing
3576 function uses a generator expression when at the same time the
3577 executed code is closing a paused generator.
Amaury Forgeot d'Arc0d75f092007-11-13 21:54:28 +00003578
Raymond Hettinger1760c8a2007-11-08 02:52:43 +00003579- sets and frozensets now have an isdisjoint() method.
3580
Raymond Hettinger3f8caa32007-10-24 01:28:33 +00003581- optimize the performance of builtin.sum().
3582
Neal Norwitz44f326e2007-10-05 05:29:17 +00003583- Fix warnings found by the new version of the Coverity checker.
3584
Georg Brandl3ee81df2008-05-17 18:14:43 +00003585- The enumerate() builtin function is no longer bounded to sequences
3586 smaller than LONG_MAX. Formerly, it raised an OverflowError. Now,
3587 automatically shifts from ints to longs.
Raymond Hettinger8f669372007-10-03 21:18:11 +00003588
Georg Brandl3ee81df2008-05-17 18:14:43 +00003589- Issue #1686386: Tuple's tp_repr did not take into account the
3590 possibility of having a self-referential tuple, which is possible
3591 from C code. Nor did object's tp_str consider that a type's tp_str
3592 could do something that could lead to an inifinite recursion.
3593 Py_ReprEnter() and Py_EnterRecursiveCall(), respectively, fixed the
3594 issues.
Brett Cannon0b14f242007-09-30 19:45:10 +00003595
Georg Brandl3ee81df2008-05-17 18:14:43 +00003596- Issue #1164: It was possible to trigger deadlock when using the
3597 'print' statement to write to a file since the GIL was not released
3598 as needed. Now PyObject_Print() does the right thing along with
3599 various tp_print implementations of the built-in types and those in
3600 the collections module.

Georg Brandl3ee81df2008-05-17 18:14:43 +00003602- Issue #1147: Exceptions were directly allowing string exceptions in
3603 their throw() method even though string exceptions no longer
3604 allowed.
Brett Cannon4c20bc42007-09-11 21:02:28 +00003605

Brett Cannon1e534b52007-09-07 04:18:30 +00003609- Issue #1202533: Fix infinite recursion calls triggered by calls to
Georg Brandl3ee81df2008-05-17 18:14:43 +00003610 PyObject_Call() never calling back out to Python code to trigger
3611 recursion depth updates/checks. Required the creation of a static
3612 RuntimeError instance in case normalizing an exception put the
3613 recursion check value past its limit. Fixes crashers

Neal Norwitz0ac60192007-05-27 04:08:54 +00003629- Add new attribute names for function objects. All the func_* become
Georg Brandl3ee81df2008-05-17 18:14:43 +00003630 __*__ attributes. (Some already existed, e.g., __doc__ and
3631 __name__.)
Neal Norwitz0ac60192007-05-27 04:08:54 +00003632
Neal Norwitz8b2bfbc2007-05-23 06:35:32 +00003633- Add -3 option to the interpreter to warn about features that are

Georg Brandl3ee81df2008-05-17 18:14:43 +00003640 "except E as target:". This is to provide forwards compatibility
3641 with Python 3.0.
Collin Winter62903052007-05-18 23:11:24 +00003642
Brett Cannon229cee22007-05-05 01:34:02 +00003643- Deprecate BaseException.message as per PEP 352.

3661
Guido van Rossum143b5642007-03-23 04:58:42 +00003662- Bug #1683368: The object.__init__() and object.__new__() methods are
3663 now stricter in rejecting excess arguments. The only time when
3664 either allows excess arguments is when it is not overridden and the
3665 other one is. For backwards compatibility, when both are
3666 overridden, it is a deprecation warning (for now; maybe a Py3k
Guido van Rossum234b1ff2007-03-23 19:39:01 +00003667 warning later). Also, type.__init__() insists on the same signature
3668 as supported by type.__new__().
Guido van Rossum143b5642007-03-23 04:58:42 +00003669
Georg Brandl3ee81df2008-05-17 18:14:43 +00003670- Patch #1675423: PyComplex_AsCComplex() now tries to convert an
3671 object to complex using its __complex__() method before falling back
3672 to the __float__() method. Therefore, the functions in the cmath
3673 module now can operate on objects that define a __complex__()
3674 method.

3691
Georg Brandl7b9c5552007-03-12 14:30:05 +00003692- Bug #1678647: write a newline after printing an exception in any
3693 case, even when converting the value to a string failed.
3694
Georg Brandl871f1bc2007-03-12 13:17:36 +00003695- The dir() function has been extended to call the __dir__() method on
Georg Brandl3ee81df2008-05-17 18:14:43 +00003696 its argument, if it exists. If not, it will work like before. This
3697 allows customizing the output of dir() in the presence of a
3698 __getattr__().
Georg Brandl871f1bc2007-03-12 13:17:36 +00003699
Collin Winter276887b2007-03-12 16:11:39 +00003700- Patch #922167: Python no longer segfaults when faced with infinitely
3701 self-recursive reload() calls (as reported by bug #742342).
3702

3707 parthensized forms. This means complex(repr(x)) now works instead of
3708 raising a ValueError.
Collin Wintere38051d2007-03-09 20:33:07 +00003709
Georg Brandlaa2321b2007-03-07 00:40:28 +00003710- Patch #703779: unset __file__ in __main__ after running a file. This
Georg Brandl3ee81df2008-05-17 18:14:43 +00003711 makes the filenames the warning module prints much more sensible
3712 when a PYTHONSTARTUP file is used.
Georg Brandlaa2321b2007-03-07 00:40:28 +00003713

Georg Brandl0fca97a2007-03-05 22:28:08 +00003725- Patch #1674228: when assigning a slice (old-style), check for the
3726 sq_ass_slice instead of the sq_slice slot.
3727
Georg Brandl3ee81df2008-05-17 18:14:43 +00003728- When printing an unraisable error, don't print exceptions. before

Georg Brandl3ee81df2008-05-17 18:14:43 +00004354- unittest now verifies more of its assumptions. In particular,
4355 TestCase and TestSuite subclasses (not instances) are no longer
4356 accepted in TestSuite.addTest(). This should cause no
4357 incompatibility since it never made sense with ordinary subclasses
4358 -- the failure just occurred later, with a more cumbersome
4359 exception.

Georg Brandl3ee81df2008-05-17 18:14:43 +00004640- Issue #829951: In the smtplib module, SMTP.starttls() now complies
4641 with RFC 3207 and forgets any knowledge obtained from the server not
4642 obtained from the TLS negotiation itself. Patch contributed by Bill
4643 Fenner.
Gregory P. Smith2b3ba582008-01-17 08:03:17 +00004644
Georg Brandl3ee81df2008-05-17 18:14:43 +00004645- Issue #1339: The smtplib.SMTP class has been refactored a bit such
Gregory P. Smithbde4ae42008-01-17 08:35:49 +00004646 that the SMTP.starttls() caller no longer needs to call ehlo()
4647 beforehand. SMTP.starttls() now raises an exception of the server
Georg Brandl3ee81df2008-05-17 18:14:43 +00004648 does not claim to support starttls. Adds the
4649 SMTP.ehlo_or_helo_if_needed() method. Patch contributed by Bill

4730 complex, tuple, list, dict, set, and frozenset. Formerly, it would
4731 silently miscode subclasses of those types. Now, it raises a

Georg Brandl3ee81df2008-05-17 18:14:43 +00004748 time so that opening a database previously created with the DB_DUP
4749 or DB_DUPSORT flag set will keep the proper behavior on subsequent
4750 opens. Specifically: dictionary assignment to a DB object will
4751 replace all values for a given key when the database allows
4752 duplicate values. DB users should use DB.put(k, v) when they want
4753 to store duplicates; not DB[k] = v.
Gregory P. Smithec10a4a2007-11-05 02:32:26 +00004754

4760 characters with ASCII value less than 32. Also, it correctly quotes
4761 dots only if they occur on a single line, as opposed to the previous
4762 behavior of quoting dots if they are the second character of any
4763 line.
Georg Brandl4aef7272007-03-13 22:49:43 +00004764

Georg Brandl3ee81df2008-05-17 18:14:43 +00005093- ``PySet_Add()`` can now modify a newly created frozenset. Similarly
5094 to ``PyTuple_SetItem``, it can be used to populate a brand new
5095 frozenset; but it does not steal a reference to the added item.

Vinay Sajipb7edfc42008-04-02 21:10:23 +00005097- Added ``PySet_Check()`` and ``PyFrozenSet_Check()`` to the set API.

Georg Brandl3ee81df2008-05-17 18:14:43 +00005099- Backport of PyUnicode_FromString(), _FromStringAndSize(), _Format
5100 and _FormatV from Python 3.0. Made PyLong_AsSsize_t and
5101 PyLong_FromSsize_t public functions.
Georg Brandl6caad7d2008-01-26 14:19:22 +00005102
5103- Patch #1720595: add T_BOOL to the range of structmember types.
5104
5105- Issue #1534: Added ``PyFloat_GetMax()``, ``PyFloat_GetMin()`` and
5106 ``PyFloat_GetInfo()`` to the float API.
5107
Georg Brandl3ee81df2008-05-17 18:14:43 +00005108- Issue #1521: On 64bit platforms, using PyArgs_ParseTuple with the t#
5109 of w# format code incorrectly truncated the length to an int, even
5110 when PY_SSIZE_T_CLEAN is set. The str.decode method used to return
5111 incorrect results with huge strings.
Georg Brandl6caad7d2008-01-26 14:19:22 +00005112
Georg Brandl3ee81df2008-05-17 18:14:43 +00005113- Issue #1629: Renamed Py_Size, Py_Type and Py_Refcnt to Py_SIZE,
5114 Py_TYPE and Py_REFCNT.
Georg Brandl6caad7d2008-01-26 14:19:22 +00005115
Georg Brandl3ee81df2008-05-17 18:14:43 +00005116- PEP 3123: Provide forward compatibility with Python 3.0, while
5117 keeping backwards compatibility. Add Py_Refcnt, Py_Type, Py_Size,
5118 and PyVarObject_HEAD_INIT.
Georg Brandl6caad7d2008-01-26 14:19:22 +00005119
Georg Brandl3ee81df2008-05-17 18:14:43 +00005120- Py_ssize_t fields work in structmember when HAVE_LONG_LONG is not
5121 defined.
Georg Brandl6caad7d2008-01-26 14:19:22 +00005122
5123- Patch #1733960: Allow T_LONGLONG to accept ints.
5124
5125- T_PYSSIZET can now be used in PyMemberDef lists for Py_ssize_t members.
5126
Christian Heimes000a0742008-01-03 22:16:32 +00005127- Added a new API function ``PyImport_ImportModuleNoBlock``.
5128
Georg Brandl6caad7d2008-01-26 14:19:22 +00005129- Bug #1637022: Prefix AST symbols with _Py_.
5130
5131- Fix some leftovers from the conversion from int to Py_ssize_t
5132 (relevant to strings and sequences of more than 2**31 items).
5133
5134- Make _PyGILState_NoteThreadState() static, it was not used anywhere
5135 outside of pystate.c and should not be necessary.
5136
Georg Brandl3ee81df2008-05-17 18:14:43 +00005137- ``PyImport_Import`` and ``PyImport_ImportModule`` now always do
5138 absolute imports. In earlier versions they might have used relative
5139 imports under some conditions.
Christian Heimes000a0742008-01-03 22:16:32 +00005140
Georg Brandl3ee81df2008-05-17 18:14:43 +00005141- Added case insensitive comparison methods ``PyOS_stricmp(char*,
5142 char*)`` and ``PyOS_strnicmp(char*, char*, Py_ssize_t)``.
Christian Heimes000a0742008-01-03 22:16:32 +00005143
Georg Brandl3ee81df2008-05-17 18:14:43 +00005144- Bug #1542693: remove semi-colon at end of PyImport_ImportModuleEx
5145 macro so it can be used as an expression.

Georg Brandl3ee81df2008-05-17 18:14:43 +00005151- Patch #1706: Drop support for Win9x, WinME and NT4. Python now
5152 requires Windows 2000 or greater. The _WINVER and NTDDI_VERSION
5153 macros are set to Win2k for x86/32bit builds and WinXP for AMD64
5154 builds.
Christian Heimes95d64472008-02-09 19:55:22 +00005155
Georg Brandl3ee81df2008-05-17 18:14:43 +00005156- Conditionalize definition of _CRT_SECURE_NO_DEPRECATE and
5157 _CRT_NONSTDC_NO_DEPRECATE.

Georg Brandl3ee81df2008-05-17 18:14:43 +00005169- Removed the macfs module. It had been deprecated since Python 2.5.
5170 This lead to the deprecation of macostools.touched() as it relied
5171 solely on macfs and was a no-op under OS X.
