Benjamin Peterson4f51baf2009-12-05 18:40:02 +000019What's New in Python 2.7 alpha 2?
20=================================
21
Benjamin Petersonaa7e51f2010-01-09 16:34:06 +000022*Release date: 2010-01-09*
Benjamin Peterson4f51baf2009-12-05 18:40:02 +000023
24Core and Builtins
25-----------------
26
Benjamin Petersonecdae192010-01-04 00:43:01 +000027- The __complex__ method is now looked up on the class of instances to make it
28 consistent with other special methods.
29
Antoine Pitrou5b7139a2010-01-02 21:12:58 +000030- Issue #7462: Implement the stringlib fast search algorithm for the `rfind`,
31 `rindex`, `rsplit` and `rpartition` methods. Patch by Florent Xicluna.
32
Mark Dickinson1b34d252010-01-01 17:27:30 +000033- Issue #5080: A number of functions and methods previously produced a
34 DeprecationWarning when passed a float argument where an integer was
35 expected. These functions and methods now raise TypeError instead.
36 The majority of the effects of this change are in the extension
37 modules, but some core functions and methods are affected: notably
38 the 'chr', 'range' and 'xrange' builtins, and many unicode/str
39 methods.
40
Benjamin Peterson0f02d392009-12-30 19:34:10 +000041- Issue #7604: Deleting an unset slotted attribute did not raise an
42 AttributeError.
43
Mark Dickinson99d652e2009-12-30 12:12:23 +000044- Issue #7534: Fix handling of IEEE specials (infinities, nans,
45 negative zero) in ** operator. The behaviour now conforms to that
46 described in C99 Annex F.
47
Amaury Forgeot d'Arcc8a2ce72009-12-29 23:06:17 +000048- Issue #7579: the msvcrt module now has docstrings for all its functions.
49
Amaury Forgeot d'Arc8645a5c2009-12-29 22:03:38 +000050- Issue #7413: Passing '\0' as the separator to datetime.datetime.isoformat()
51 used to drop the time part of the result.
52
Mark Dickinson46572832009-12-27 14:55:57 +000053- Issue #1811: improve accuracy and cross-platform consistency for
54 true division of integers: the result of a/b is now correctly
55 rounded for ints a and b (at least on IEEE 754 platforms), and in
56 particular does not depend on the internal representation of a long.
57
Ezio Melottif84caf42009-12-24 22:25:17 +000058- Issue #6108: unicode(exception) and str(exception) should return the same
59 message when only __str__ (and not __unicode__) is overridden in the subclass.
60
Ronald Oussoren92919a62009-12-24 13:30:58 +000061- Issue #6834: replace the implementation for the 'python' and 'pythonw'
62 executables on OSX.
63
64 These executables now work properly with the arch(1) command:
65 ``arch -ppc python`` will start a universal binary version of python
66 in PPC mode (unlike previous releases).
67
R. David Murray0a0a1a82009-12-14 16:28:26 +000068- Issue #1680159: unicode coercion during an 'in' operation no longer masks
69 the underlying error when the coercion fails for the left hand operand.
70
Benjamin Peterson4895af42009-12-13 16:36:53 +000071- Issue #7491: Metaclass's __cmp__ method was ignored.
72
Antoine Pitrou2a08b422009-12-13 16:18:14 +000073- Issue #7466: segmentation fault when the garbage collector is called
Antoine Pitrou54584182010-01-07 17:54:10 +000074 in the middle of populating a tuple. Patch by Florent Xicluna.
Antoine Pitrou2a08b422009-12-13 16:18:14 +000075

81 gcc when it has a fully qualified configuration prefix. Initial patch
82 by Arfrever.
83
Antoine Pitrou80157252010-01-08 19:20:17 +000084- Issue #7092: Remove py3k warning when importing cPickle. 2to3 handles
85 renaming of `cPickle` to `pickle`. The warning was annoying since there's
86 no alternative to cPickle if you care about performance. Patch by Florent
87 Xicluna.
88
Antoine Pitrou0d423b82010-01-07 17:46:49 +000089- Issue #7455: Fix possible crash in cPickle on invalid input. Patch by
Antoine Pitrou54584182010-01-07 17:54:10 +000090 Victor Stinner.
Antoine Pitrou0d423b82010-01-07 17:46:49 +000091

93 when using the -3 flag. Patch by Florent Xicluna.
94
Antoine Pitrou673ddf92010-01-03 22:29:56 +000095- Issue #7471: Improve the performance of GzipFile's buffering mechanism,
96 and make it implement the `io.BufferedIOBase` ABC to allow for further
97 speedups by wrapping it in an `io.BufferedReader`. Patch by Nir Aides.
98
99- Issue #3972: httplib.HTTPConnection now accepts an optional source_address
Gregory P. Smith9d325212010-01-03 02:06:07 +0000100 parameter to allow specifying where your connections come from.

117- Issue #7231: urllib2 cannot handle https with proxy requiring auth.
Senthil Kumaran7713acf2009-12-20 06:05:13 +0000118 Patch by Tatsuhiro Tsujikawa.
119
Benjamin Petersonddd392c2009-12-13 19:19:07 +0000120- Issue #7349: Make methods of file objects in the io module accept None as an
121 argument where file-like objects (ie StringIO and BytesIO) accept them to mean
122 the same as passing no argument.
123
Benjamin Petersonc4771d22009-12-13 17:31:31 +0000124- Issue #7348: StringIO.StringIO.readline(-1) now acts as if it got no argument
125 like other file objects.
126

145 PyArg_ParseTupleAndKeywords, PyArg_VaParse,
146 PyArg_VaParseTupleAndKeywords and PyArg_Parse no longer accept float
147 arguments for integer format codes (other than 'L'): previously an

193-----------------
194
Amaury Forgeot d'Arcd7288712009-12-01 21:51:04 +0000195- Issue #7419: setlocale() could crash the interpreter on Windows when called
196 with invalid values.
197
Eric Smithc4ab8332009-11-29 17:40:57 +0000198- Issue #3382: 'F' formatting for float and complex now convert the
199 result to upper case. This only affects 'inf' and 'nan', since 'f'
200 no longer converts to 'g' for large values.
Amaury Forgeot d'Arcd7288712009-12-01 21:51:04 +0000201
Mark Dickinson9dd5e162009-11-23 20:54:09 +0000202- Remove switch from "%f" formatting to "%g" formatting for floats
203 larger than 1e50 in absolute value.
204
Mark Dickinson18cfada2009-11-23 18:46:41 +0000205- Remove restrictions on precision when formatting floats. E.g.,
206 "%.120g" % 1e-100 used to raise OverflowError, but now gives the
207 requested 120 significant digits instead.
208
Benjamin Peterson89b1a5c2009-11-19 22:58:01 +0000209- Add Py3k warnings for parameter names in parenthesis.
210
Benjamin Peterson48f0a8d2009-11-19 23:19:29 +0000211- Issue #7362: Give a proper error message for def f((x)=3): pass.
Benjamin Peterson89b1a5c2009-11-19 22:58:01 +0000212
Ronald Oussoren315cd0c2009-11-19 16:25:21 +0000213- Issue #7085: Fix crash when importing some extensions in a thread
214 on MacOSX 10.6.
215
Mark Dickinsonb678de82009-11-19 18:41:49 +0000216- Issue #7117: repr(x) for a float x returns a result based on the
217 shortest decimal string that's guaranteed to round back to x under
218 correct rounding (with round-half-to-even rounding mode).
219 Previously it gave a string based on rounding x to 17 decimal digits.
220 repr(x) for a complex number behaves similarly. On platforms where
221 the correctly-rounded strtod and dtoa code is not supported (see below),
222 repr is unchanged.
223
224- Issue #7117: On almost all platforms: float-to-string and
225 string-to-float conversions within Python are now correctly rounded.
226 Places these conversions occur include: str for floats and complex
227 numbers; the float and complex constructors; old-style and new-style
228 numeric formatting; serialization and deserialization of floats and
229 complex numbers using marshal, pickle and json; parsing of float and
230 imaginary literals in Python code; Decimal-to-float conversion.
231
232 The conversions use a Python-adapted version of David Gay's
233 well-known dtoa.c, providing correctly-rounded strtod and dtoa C
234 functions. This code is supported on Windows, and on Unix-like
235 platforms using gcc, icc or suncc as the C compiler. There may be a
236 small number of platforms on which correct operation of this code
237 cannot be guaranteed, so the code is not used: notably, this applies
238 to platforms where the C double format is not IEEE 754 binary64, and
239 to platforms on x86 hardware where the x87 FPU is set to 64-bit
240 precision and Python's configure script is unable to determine how
241 to change the FPU precision. On these platforms conversions use the
242 platform strtod and dtoa, as before.
243
Mark Dickinsonbd15a062009-11-18 19:33:35 +0000244- Issue #7117: Backport round implementation from Python 3.x. round
Mark Dickinsonb678de82009-11-19 18:41:49 +0000245 now uses the correctly-rounded string <-> float conversions
246 described above (when available), and so produces correctly rounded
247 results that will display nicely under the float repr. There are
248 two related small changes: (1) round now accepts any class with an
249 __index__ method for its second argument (but no longer accepts
Mark Dickinsonbd15a062009-11-18 19:33:35 +0000250 floats for the second argument), and (2) an excessively large second
251 integer argument (e.g., round(1.234, 10**100)) no longer raises an
252 exception.
253
Philip Jenveyfab8be22009-11-17 02:42:26 +0000254- Issue #1757126: Fix the cyrillic-asian alias for the ptcp154 encoding.
255
Benjamin Petersone36199b2009-11-12 23:39:44 +0000256- Fix several issues with compile(). The input can now contain Windows and Mac
257 newlines and is no longer required to end in a newline.
258
Mark Dickinsonc04c7c52009-10-26 22:28:14 +0000259- Remove length limitation when constructing a complex number from a
260 unicode string.
261
Raymond Hettingerfa7dadd2009-11-01 20:45:16 +0000262- Issue #7244: itertools.izip_longest() no longer ignores exceptions
263 raised during the formation of an output tuple.
264

276
Benjamin Peterson196b0922009-10-15 15:44:46 +0000277- Issue #7140: The __dict__ of a module should not be cleared unless the module
278 is the only object holding a reference to it.
279
Neil Schemenauer7fdd1cb2009-10-14 17:17:14 +0000280- Issue #1754094: Improve the stack depth calculation in the compiler.
281 There should be no other effect than a small decrease in memory use.
282 Patch by Christopher Tur Lesniewski-Laas.
283
Antoine Pitroubeaf6a02009-10-11 21:03:26 +0000284- Issue #7084: Fix a (very unlikely) crash when printing a list from one

Mark Dickinsonb1d45852009-05-11 15:33:08 +0000394- Issue #5981: Fix three minor inf/nan issues in float.fromhex:
395 (1) inf and nan strings with trailing whitespace were incorrectly
396 rejected; (2) parsing of strings representing infinities and nans
397 was locale aware; and (3) the interpretation of fromhex('-nan')
398 didn't match that of float('-nan').
399
Eric Smitha985a3a2009-05-05 18:26:08 +0000400- Issue #5920: For float.__format__, change the behavior with the
401 empty presentation type (that is, not one of 'e', 'f', 'g', or 'n')
402 to be like 'g' but with at least one decimal point and with a
403 default precision of 12. Previously, the behavior the same but with
404 a default precision of 6. This more closely matches str(), and
405 reduces surprises when adding alignment flags to the empty
406 presentation type. This also affects the new complex.__format__ in
407 the same way.
408
R. David Murray7ba8e1c2009-05-04 22:16:24 +0000409- Issue #5890: in subclasses of 'property' the __doc__ attribute was

472 untrackable objects are not tracked by the garbage collector. This can
473 reduce the size of collections and therefore the garbage collection overhead
474 on long-running programs, depending on their particular use of datatypes.
475
Mark Dickinson0b666bf2009-03-23 18:25:13 +0000476- Issue #5512: Rewrite PyLong long division algorithm (x_divrem) to

478 are now between 50% and 150% faster.
479
Mark Dickinsonefc82f72009-03-20 15:51:55 +0000480- Issue #4258: Make it possible to use base 2**30 instead of base
481 2**15 for the internal representation of integers, for performance
482 reasons. Base 2**30 is enabled by default on 64-bit machines. Add
483 --enable-big-digits option to configure, which overrides the
484 default. Add sys.long_info structseq to provide information about
485 the internal format.
486
Benjamin Peterson6ffe8522009-03-18 20:52:15 +0000487- Issue #4034: Fix weird attribute error messages of the traceback object. (As a
488 result traceback.__members__ no longer exists.)
489
Mark Dickinson6b265f12009-03-18 16:07:26 +0000490- Issue #4474: PyUnicode_FromWideChar now converts characters outside
491 the BMP to surrogate pairs, on systems with sizeof(wchar_t) == 4

Eric Smith6f42edb2009-03-14 11:57:26 +0000494- Issue #5237: Allow auto-numbered fields in str.format(). For
495 example: '{} {}'.format(1, 2) == '1 2'.
496
Brett Cannon6c4cff02009-03-11 04:51:06 +0000497- Issue #3652: Make the 'line' argument for warnings.showwarning() a
498 requirement. Means the DeprecationWarning from Python 2.6 can go away.
499
Eric Smithe9fb6862009-02-20 14:02:36 +0000500- Issue #5247: Improve error message when unknown format codes are

505 for ints and longs.
506
Mark Dickinson2ffb26f2009-02-15 10:13:41 +0000507- Issue #5260: Long integers now consume less memory: average
508 saving is 2 bytes per long on a 32-bit system and 6 bytes per long
509 on a 64-bit system.
510
Antoine Pitrou76a4b892009-02-13 13:52:33 +0000511- Issue #5186: Reduce hash collisions for objects with no __hash__ method by
512 rotating the object pointer by 4 bits to the right.

518
Georg Brandl29c6a282009-04-05 20:23:13 +0000519- Issue #1242657: the __len__() and __length_hint__() calls in several tools
Raymond Hettingerb5163702009-02-02 21:50:13 +0000520 were suppressing all exceptions. These include list(), filter(), map(),
521 zip(), and bytearray().
522
Benjamin Peterson596d3062009-01-19 15:42:23 +0000523- os.ftruncate raises OSErrors instead of IOErrors for consistency with other os

551 an existing .py counterpart, override the co_filename attributes of all
552 code objects if the original filename is obsolete (which can happen if the
553 file has been renamed, moved, or if it is accessed through different paths).

608
Vinay Sajip213faca2008-12-03 23:22:58 +0000609- Issue #4233: Changed semantic of ``_fileio.FileIO``'s ``close()``
Amaury Forgeot d'Arc32265652008-11-20 23:34:31 +0000610 method on file objects with closefd=False. The file descriptor is still
611 kept open but the file object behaves like a closed file. The ``FileIO``
612 object also got a new readonly attribute ``closefd``.
613
Benjamin Peterson46cc6d12008-11-19 21:49:09 +0000614- Issue #4348: Some bytearray methods returned that didn't cause any change to

631
Benjamin Peterson399b1fe2008-10-25 02:53:28 +0000632- Using ``nonlocal`` as a variable name will now raise a Py3k SyntaxWarning
Georg Brandl7fb00ad2008-10-25 07:00:52 +0000633 because it is a reserved word in 3.x.

Hirokazu Yamamoto10a018c2008-10-09 10:00:30 +0000635- On windows, os.chdir given unicode was not working if GetCurrentDirectoryW
636 returned a path longer than MAX_PATH. (But It's doubtful this code path is
637 really executed because I cannot move to such directory on win2k)
638
Amaury Forgeot d'Arcd78b9dc2008-10-07 20:32:10 +0000639- Issue #4069: When set.remove(element) is used with a set element, the element
640 is temporarily replaced with an equivalent frozenset. But the eventual
641 KeyError would always report the empty frozenset([]) as the missing key. Now
642 it correctly refers to the initial element.

660 returned them on 64bit platforms.
661
Walter Dörwalded960ac2009-05-03 22:36:33 +0000662- Issue #5108: Handle %s like %S and %R in PyUnicode_FromFormatV(): Call
663 PyUnicode_DecodeUTF8() once, remember the result and output it in a second
664 step. This avoids problems with counting UTF-8 bytes that ignores the effect
665 of using the replace error handler in PyUnicode_DecodeUTF8().
666
Walter Dörwald726ba8e2009-05-06 14:32:35 +0000667- Issue #3739: The unicode-internal encoder now reports the number of characters
668 consumed like any other encoder (instead of the number of bytes).
669
Benjamin Peterson91c12eb2009-12-03 02:52:39 +0000670- Issue #2422: When compiled with the ``--with-valgrind`` option, the
671 pymalloc allocator will be automatically disabled when running under
672 Valgrind. This gives improved memory leak detection when running
673 under Valgrind, while taking advantage of pymalloc at other times.

Nick Coghlan49868cb2009-11-15 07:30:34 +0000742- Issue #6816: runpy now provides a run_path function that allows Python code
743 to execute file paths that refer to source or compiled Python files as well
744 as zipfiles, directories and other valid sys.path entries that contain a

Martin v. Löwis9fa5a282008-09-11 06:53:30 +00002053- Issue #3642: Suppress warning in obmalloc when size_t is larger than uint.

Amaury Forgeot d'Arc05e34492008-09-10 22:04:45 +00002055- Issue #3743: In a few places, PY_FORMAT_SIZE_T was incorrectly used with
2056 PyString_FromFormat or PyErr_Format to display size_t values. The macro
2057 PY_FORMAT_SIZE_T is designed to select the correct format for the OS
2058 ``printf`` function, whereas PyString_FromFormat has an independent
2059 implementation and uses "%zd" on all platforms for size_t values.
2060 This makes a difference on win64, where ``printf`` needs "%Id" to display
2061 64bit values.

Benjamin Peterson97179b02008-09-09 20:55:01 +00002063- Issue #3634: _weakref.ref(Exception).__init__() gave invalid return value on

2067 object; previously an int would be returned for small values. the __long__
2068 method is allowed to return either an int or a long, but the behaviour of
2069 float objects should not change to respect backward compatibility.

Vinay Sajip35e3b032008-09-01 14:33:59 +00002077 PyArg_ParseTuple and friends, which occurred when the argument for "s*"
Antoine Pitroud4ae97b2008-08-29 18:39:48 +00002078 was correctly parsed but parsing of subsequent arguments failed.

Vinay Sajip35e3b032008-09-01 14:33:59 +00002080- Issue #2534: speed up isinstance() and issubclass() by 50-70%, so as to
Antoine Pitrou0668c622008-08-26 22:42:08 +00002081 match Python 2.5 speed despite the __instancecheck__ / __subclasscheck__
2082 mechanism. In the process, fix a bug where isinstance() and issubclass(),
2083 when given a tuple of classes as second argument, were looking up
2084 __instancecheck__ / __subclasscheck__ on the tuple rather than on each
2085 type object.

2230-----------------
2231
Guido van Rossumf8402962008-08-20 15:01:50 +00002232- Issue #1878: Remove Py_TPFLAGS_HAVE_VERSION_TAG from
2233 Py_TPFLAGS_DEFAULT when not building the core. This means 3rd party
2234 extensions do not automatically benefit from the class attribute
2235 cache; they will have to explicitly add Py_TPFLAGS_HAVE_VERSION_TAG
2236 to their tp_flags field if they care. This is a backwards
2237 compatibility feature; in 3.0, all types will use the cache by
2238 default.
2239
Benjamin Petersonf647dc12008-08-20 01:27:30 +00002240- Keyword arguments can now follow starred arguments. (``f(a, *args,

2242
Thomas Heller0ad5ae02008-08-19 19:25:04 +00002243- ctypes function pointers that are COM methods have a boolean True
2244 value again.

2255
Amaury Forgeot d'Arc39fd6722008-07-31 21:28:03 +00002256- Issue #3479: On platforms where sizeof(int) is smaller than sizeof(long)
2257 (64bit Unix, for example), unichr() would truncate its argument and return
2258 u'\x00' for unichr(2**32). Now it properly raises an OverflowError.

Neal Norwitze7d8be82008-07-31 17:17:14 +00002260- Apply security patches from Apple.

Amaury Forgeot d'Arce4921fe2008-07-21 22:00:38 +00002268- Issue #2378: An unexpected UnboundLocalError or NameError could appear when
2269 the python debugger steps into a class statement: the free variables (local
2270 variables defined in an outer scope) would be deleted from the outer scope.
2271
Gregory P. Smith0470bab2008-07-22 04:46:32 +00002272- Issue #2620: Overflow checking when allocating or reallocating memory
2273 was not always being done properly in some python types and extension
2274 modules. PyMem_MALLOC, PyMem_REALLOC, PyMem_NEW and PyMem_RESIZE have
2275 all been updated to perform better checks and places in the code that
2276 would previously leak memory on the error path when such an allocation
2277 failed have been fixed.

2283
Benjamin Petersone977ad42008-08-20 01:42:01 +00002284- The methods ``is_in_tuple()``, ``is_vararg()``, and ``is_keywordarg()`` of
2285 symtable.Symbol have been deprecated for removal in 3.0 and the next release.
2286
Amaury Forgeot d'Arc351ffb82008-08-18 19:23:47 +00002287- Issue #2234: distutils failed for some versions of the cygwin compiler. The
2288 version reported by these tools does not necessarily follow the python
2289 version numbering scheme, so the module is less strict when parsing it.
2290
Nick Coghlanf70385a2008-08-18 12:42:46 +00002291- Issue #2235: Added Py3k warnings for types which will become unhashable
2292 under the stricter __hash__ inheritance rules in 3.0. Several types
2293 which did not meet the rules for hash invariants and were already
2294 unhashable in 3.0 have now been explicitly flagged as unhashable in
2295 2.6 as well (collections.Mapping, collections.Set, unittest.TestSuite,
2296 xml.dom.minidom.NamedNodeMap, numbers.Number, UserList.UserList)
2297
Brett Cannon88f801d2008-08-18 00:46:22 +00002298- Update __all__ for cookielib, csv, os, urllib2, and weakref to include things

2320 after a 302 response in the case of not going through a proxy.
2321
Antoine Pitroub90a8be2008-08-15 21:03:21 +00002322- Issue #2676: in the email package, content-type parsing was hanging on

2324 regular expression.
2325

2327 thread-safe.
2328
Brett Cannonbf3157b2008-08-14 05:00:03 +00002329- Silence the DeprecationWarning of rfc822 when it is imported by mimetools
2330 since mimetools itself is deprecated. Because modules are cached, all
2331 subsequent imports of rfc822 will not raise a visible DeprecationWarning.
2332
Antoine Pitrou9fcd4b32008-08-11 17:21:36 +00002333- Issue #3134: shutil referenced undefined WindowsError symbol.

2339 version that did not raise a DeprecationWarning under -3.
2340

2345 to _sre.compile() will now be rejected. This should not affect anybody
2346 since the re.compile() function never generates invalid re-bytecode.
2347
Skip Montanaroa032bf42008-08-08 22:52:51 +00002348- Issue #3436: Make csv.DictReader's fieldnames attribute a property so that
2349 upon first access it can be automatically initialized from the csv file if
2350 it wasn't initialized during instantiation.
2351
Brett Cannon3aa2a492008-08-06 22:28:09 +00002352- Issue #2338: Create imp.reload() to help with transitioning to Python 3.0 as
2353 the reload() built-in has been removed.
2354
Brett Cannon7e30b672008-08-04 21:52:25 +00002355- Changed code in the following modules/packages to remove warnings raised
Brett Cannonc1b76e42008-08-09 23:06:16 +00002356 while running under the ``-3`` flag: aifc, asynchat, asyncore, bdb, bsddb,

2364 raised an AttributeError.
2365
Benjamin Peterson01a24322008-07-28 23:35:27 +00002366- Issue #2523: Fix quadratic behaviour when read()ing a binary file without
Antoine Pitroude781a42008-08-09 12:43:23 +00002367 asking for a specific length. This problem only affected files opened
2368 using the new "io" module, not the built-in open() function.
Benjamin Peterson01a24322008-07-28 23:35:27 +00002369

Antoine Pitrou5fdfa3e2008-07-25 19:42:26 +00002393- Issue #3394: zipfile.writestr sets external attributes when passed a
2394 file name rather than a ZipInfo instance, so files are extracted with
2395 mode 0600 rather than 000 under Unix.
2396
Gregory P. Smitha36f8fe2008-08-04 00:13:29 +00002397- Issue #1857: subprocess.Popen.poll gained an additional _deadstate keyword
2398 argument in python 2.5, this broke code that subclassed Popen to include its

Nick Coghlan6e8fef02008-08-18 13:14:22 +00002409- Issue #2235: the C API function PyObject_HashNotImplemented and its
2410 interaction with the tp_hash slot (added in 2.6b2) are now documented
2411
Nick Coghlan2a0c2b12008-08-04 12:47:17 +00002412- Issue #643841: The language reference now provides more detailed
2413 coverage of the lookup process for special methods. The disclaimers
2414 regarding lack of coverage of new-style classes have also been
2415 removed, since the coverage is now fairly reasonable.

2419================================
2420
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00002421*Release date: 17-Jul-2008*
2422
Raymond Hettingere3ae6552008-06-20 04:18:15 +00002423Core and Builtins
2424-----------------
2425
Georg Brandl3e483f62008-07-16 22:57:41 +00002426- Issue #3156: Fix inconsistent behavior of the bytearray type: all
2427 its methods now allow for items objects that can be converted to
2428 an integer using operator.index().
2429
Mark Dickinson64b7e502008-07-16 09:40:03 +00002430- Issue #3360: Fix incorrect parsing of '020000000000.0', which
2431 produced a ValueError instead of giving the correct float.
2432
Eric Smitha5fa5a22008-07-16 00:11:49 +00002433- Issue #3083: Add alternate (#) formatting for bin, oct, hex output
2434 for str.format(). This adds the prefix 0b, 0o, or 0x, respectively.
2435
Mark Dickinson7103aa42008-07-15 19:08:33 +00002436- Issue #3008: the float type has a new instance method 'float.hex'
2437 and a new class method 'float.fromhex' to convert floating-point
2438 numbers to and from hexadecimal strings, respectively.
2439
Nick Coghlan6d6bd442008-07-15 15:40:22 +00002440- Issue #2235: __hash__ is once again inherited by default. To allow
2441 collections.Hashable to remain meaningful in the presence of the
2442 default hash implementation (object.__hash__), it is now possible
2443 to explicit block inheritance of hash by setting __hash__=None at
2444 the Python level, or tp_hash=PyObject_HashNotImplemented at the C
2445 level.
2446
Nick Coghlanb028f502008-07-13 14:52:36 +00002447- Issue #3221: Issue a RuntimeWarning instead of raising SystemError if
2448 the parent module cannot be found while performing an absolute import.
2449 This means that an incorrectly defined __package__ attribute will
2450 now only prevent relative imports in that module rather than causing
2451 all imports from that module to fail.
2452
Nick Coghlan14ff9942008-07-08 14:21:42 +00002453- Issue #2517: Allow unicode messages in Exceptions again by correctly
2454 bypassing the instance dictionary when looking up __unicode__ on
2455 new-style classes.
2456
Amaury Forgeot d'Arcbdd941f2008-07-01 20:38:04 +00002457- Issue #3242: Fix a crash inside the print statement, if sys.stdout is
2458 set to a custom object whose write() method happens to install
2459 another file in sys.stdout.
2460
Amaury Forgeot d'Arc1f40c8a2008-06-30 22:42:40 +00002461- Issue #3088: Corrected a race condition in classes derived from
2462 threading.local: the first member set by a thread could be saved in
2463 another thread's dictionary.
2464
Mark Dickinson1ec2fcd2008-06-20 14:53:43 +00002465- Issue #3004: Minor change to slice.indices(): the start and stop
2466 arguments are now treated identically, making the behaviour easier
2467 to describe and understand. For example, slice(None, -10,
2468 1).indices(9) now returns (0, 0, 1) instead of (0, -1, 1), and
2469 slice(None, 10, -1).indices(10) returns (9, 9, -1) instead of (9,
2470 10, -1).
2471
Georg Brandl278fc502008-07-19 12:46:12 +00002472- Issue #3219: Calling a function with repeated keyword arguments,
2473 f(a=2, a=23), would not cause a syntax error. This was a regression
2474 from 2.4 caused by the switch to the new compiler.
Benjamin Peterson175e4d92008-07-01 19:34:52 +00002475
Georg Brandl278fc502008-07-19 12:46:12 +00002476- Issue #2862: Make int and float freelist management consistent with
2477 other freelists. Changes their CompactFreeList apis into
2478 ClearFreeList apis and calls them via gc.collect().
Gregory P. Smith2fe77062008-07-06 03:35:58 +00002479

Thomas Heller57adf222008-08-14 19:10:48 +00002483- Issue #3554: ctypes.string_at and ctypes.wstring_at did call Python
2484 api functions without holding the GIL, which could lead to a fatal
2485 error when they failed.
2486
Martin v. Löwisaabf4042008-08-02 07:20:25 +00002487- Issue #799428: Fix Tkinter.Misc._nametowidget to unwrap Tcl command objects.

Jesse Noller13e9d582008-07-16 14:32:36 +00002495- Issue #3125: Remove copy_reg in multiprocessing and replace it with
2496 ForkingPickler.register() to resolve conflict with ctypes.
2497
Vinay Sajip51e65192008-07-18 09:01:10 +00002498- Issue #3090: Fixed ARCHFLAGS parsing on OS/X
Jesse Noller13e9d582008-07-16 14:32:36 +00002499
Thomas Heller880f5292008-07-15 19:39:38 +00002500- Issue #3313: Fixed a crash when a failed dlopen() call does not set
2501 a valid dlerror() message.
2502
Thomas Heller2bad6572008-07-15 17:19:50 +00002503- Issue #3258: Fixed a crash when a ctypes POINTER type to an
2504 incomplete structure was created.
2505
Brett Cannon3d0b9f02008-07-13 01:15:07 +00002506- Issue #3339: dummy_thread.acquire() should not return None.

2509
Andrew M. Kuchlingcc3f2b12008-07-10 14:43:31 +00002510- Issue #3301: Bisect module behaved badly when lo was negative.
Raymond Hettinger3cd1e422008-07-10 14:03:19 +00002511
Amaury Forgeot d'Arc0f7cddc2008-07-06 21:34:39 +00002512- Issue #839496: SimpleHTTPServer used to open text files in text mode. This is
2513 both unnecessary (HTTP allows text content to be sent in several forms) and
Andrew M. Kuchlingcc3f2b12008-07-10 14:43:31 +00002514 wrong because the actual transmitted size could differ from the
Amaury Forgeot d'Arc0f7cddc2008-07-06 21:34:39 +00002515 content-length. The problem had been corrected in the 2.4 branch, but never
2516 merged into trunk.
2517
Georg Brandle78fbcc2008-07-05 10:13:36 +00002518- Issue #2663: add filtering capability to shutil.copytree().

Andrew M. Kuchlingcc3f2b12008-07-10 14:43:31 +00002529 when completed.
Facundo Batista66c52772008-07-02 16:52:55 +00002530
Nick Coghlanc060b0e2008-07-02 13:09:19 +00002531- Issue #3190: Pydoc now hides the automatic module attribute __package__ (the
2532 handling is now the same as that of other special attributes like __name__).
2533
Brett Cannon8bb8fa52008-07-02 01:57:08 +00002534- Issue #2885 (partial): The urllib.urlopen() function has been deprecated for
2535 removal in Python 3.0 in favor of urllib2.urlopen().

Georg Brandl5cc774e2008-06-11 20:28:06 +00002924 PPC64 and x86_64 support in one binary).
Ronald Oussoren5640ce22008-06-05 12:58:24 +00002925
2926 This is controlled by the configure argument ``--with-universal-archs``:
2927
2928 - ``--with-universal-archs=all``: install 4-way universal
2929
2930 - ``--with-universal-archs=32-bit``: install 2-way universal, 32-bit (the default)
2931
2932 - ``--with-universal-archs=64-bit``: install 2-way universal, 64-bit
2933
2934 This option should be used in combination with ``--enable-universalsdk=``.
2935
2936 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 +00002986- Issue #1631171: Re-implement the 'warnings' module in C (the
2987 original Python code has been kept as backup). This will allow for
2988 using the 'warning's machinery in such places as the parser where
2989 use of pure Python code is not possible. Both the ``showarning()``
2990 and ``formatwarning()`` gain an optional 'line' argument which is
2991 not called by default for backwards-compatibility reasons. Setting
2992 ``warnings.showwarning()`` to an implementation that lacks support
2993 for the ``line`` argument will raise a DeprecationWarning.

Georg Brandl3ee81df2008-05-17 18:14:43 +00003056- Issue #2550: The approach used by client/server code for obtaining
3057 ports to listen on in network-oriented tests has been refined in an
3058 effort to facilitate running multiple instances of the entire
3059 regression test suite in parallel without issue.
3060 test_support.bind_port() has been fixed such that it will always
3061 return a unique port -- which wasn't always the case with the
3062 previous implementation, especially if socket options had been set
3063 that affected address reuse (i.e. SO_REUSEADDR, SO_REUSEPORT). The
3064 new implementation of bind_port() will actually raise an exception
3065 if it is passed an AF_INET/SOCK_STREAM socket with either the
3066 SO_REUSEADDR or SO_REUSEPORT socket option set. Furthermore, if
3067 available, bind_port() will set the SO_EXCLUSIVEADDRUSE option on
3068 the socket it's been passed. This currently only applies to
3069 Windows. This option prevents any other sockets from binding to the
3070 host/port we've bound to, thus removing the possibility of the
3071 'non-deterministic' behaviour, as Microsoft puts it, that occurs
3072 when a second SOCK_STREAM socket binds and accepts to a host/port
3073 that's already been bound by another socket. The optional preferred
3074 port parameter to bind_port() has been removed. Under no
3075 circumstances should tests be hard coding ports!
3076
3077 test_support.find_unused_port() has also been introduced, which will
3078 pass a temporary socket object to bind_port() in order to obtain an
3079 unused port. The temporary socket object is then closed and
3080 deleted, and the port is returned. This method should only be used
3081 for obtaining an unused port in order to pass to an external program
3082 (i.e. the -accept [port] argument to openssl's s_server mode) or as
3083 a parameter to a server-oriented class that doesn't give you direct
3084 access to the underlying socket used.
3085
3086 Finally, test_support.HOST has been introduced, which should be used
3087 for the host argument of any relevant socket calls (i.e. bind and
3088 connect).
Trent Nelsone41b0062008-04-08 23:47:30 +00003089
3090 The following tests were updated to following the new conventions:
Georg Brandl3ee81df2008-05-17 18:14:43 +00003091 test_socket, test_smtplib, test_asyncore, test_ssl, test_httplib,
Trent Nelsone41b0062008-04-08 23:47:30 +00003092 test_poplib, test_ftplib, test_telnetlib, test_socketserver,
3093 test_asynchat and test_socket_ssl.
3094
Georg Brandl3ee81df2008-05-17 18:14:43 +00003095 It is now possible for multiple instances of the regression test
3096 suite to run in parallel without issue.

Fred Drakea8ee94b2008-03-01 02:45:07 +00003365- Issue #2051: pyc and pyo files are no longer created with permission
Barry Warsaw52973612008-03-01 02:23:38 +00003366 644. The mode is now inherited from the py file.
Christian Heimes40346852008-02-23 17:52:07 +00003367
Georg Brandlad61bc82008-02-23 15:11:18 +00003368- Issue #2067: file.__exit__() now calls subclasses' close() method.
3369
3370- Patch #1759: Backport of PEP 3129 class decorators.
Christian Heimes5224d282008-02-23 15:01:05 +00003371
Vinay Sajipb7edfc42008-04-02 21:10:23 +00003372- Issue #1881: An internal parser limit has been increased. Also see
Facundo Batistafc2d0102008-02-23 12:01:13 +00003373 issue 215555 for a discussion.
3374
Eric Smitha73fbe72008-02-23 03:09:44 +00003375- Added the future_builtins module, which contains hex() and oct().
3376 These are the PEP 3127 version of these functions, designed to be
3377 compatible with the hex() and oct() builtins from Python 3.0. They
3378 differ slightly in their output formats from the existing, unchanged
3379 Python 2.6 builtins. The expected usage of the future_builtins
3380 module is:
3381 from future_builtins import hex, oct
3382
Eric Smith7ef40bf2008-02-20 23:34:22 +00003383- Issue #1600: Modifed PyOS_ascii_formatd to use at most 2 digit
3384 exponents for exponents with absolute value < 100. Follows C99
3385 standard. This is a change on Windows, which would use 3 digits.
3386 Also, added 'n' to the formats that PyOS_ascii_formatd understands,
3387 so that any alterations it does to the resulting string will be
3388 available in stringlib/formatter.h (for float.__format__).
3389
Eric Smith5a3c1352008-02-19 13:21:56 +00003390- Implemented PEP 3101, Advanced String Formatting. This adds a new
3391 builtin format(); a format() method for str and unicode; a
3392 __format__() method to object, str, unicode, int, long, float, and
3393 datetime; the class string.Formatter; and the C API
3394 PyObject_Format().
3395
Georg Brandl3ee81df2008-05-17 18:14:43 +00003396- Fixed several potential crashes, all caused by specially crafted
3397 __del__ methods exploiting objects in temporarily inconsistent
3398 state.
Amaury Forgeot d'Arc632fad32008-02-16 20:55:24 +00003399
Vinay Sajipb7edfc42008-04-02 21:10:23 +00003400- Issue #2115: Important speedup in setting __slot__ attributes. Also
Georg Brandl3ee81df2008-05-17 18:14:43 +00003401 prevent a possible crash: an Abstract Base Class would try to access
3402 a slot on a registered virtual subclass.
Amaury Forgeot d'Arc60d6c7f2008-02-15 21:22:45 +00003403
Georg Brandl3ee81df2008-05-17 18:14:43 +00003404- Fixed repr() and str() of complex numbers with infinity or nan as
3405 real or imaginary part.
Christian Heimes2f0da532008-02-15 06:57:08 +00003406
Georg Brandl3ee81df2008-05-17 18:14:43 +00003407- Clear all free lists during a gc.collect() of the highest generation
3408 in order to allow pymalloc to free more arenas. Python may give back
3409 memory to the OS earlier.
Christian Heimes3b718a72008-02-14 12:47:33 +00003410
Georg Brandl3ee81df2008-05-17 18:14:43 +00003411- Issue #2045: Fix an infinite recursion triggered when printing a
3412 subclass of collections.defaultdict, if its default_factory is set
3413 to a bound method.
Amaury Forgeot d'Arcb01aa432008-02-08 00:56:02 +00003414
Christian Heimesf75dbef2008-02-08 00:11:31 +00003415- Fixed a minor memory leak in dictobject.c. The content of the free
3416 list was not freed on interpreter shutdown.
3417
Georg Brandl3ee81df2008-05-17 18:14:43 +00003418- Limit free list of method and builtin function objects to 256
3419 entries each.
Christian Heimes6075a822008-02-06 12:44:34 +00003420
Georg Brandl3ee81df2008-05-17 18:14:43 +00003421- Patch #1953: Added ``sys._compact_freelists()`` and the C API
3422 functions ``PyInt_CompactFreeList`` and ``PyFloat_CompactFreeList``
Christian Heimes422051a2008-02-04 18:00:12 +00003423 to compact the internal free lists of pre-allocted ints and floats.
3424
Georg Brandl3ee81df2008-05-17 18:14:43 +00003425- Issue #1983: Fixed return type of fork(), fork1() and forkpty()
3426 calls. Python expected the return type int but the fork familie
3427 returns pi_t.
Christian Heimes951cc0f2008-01-31 23:08:23 +00003428
Georg Brandl3ee81df2008-05-17 18:14:43 +00003429- Issue #1678380: Fix a bug that identifies 0j and -0j when they
3430 appear in the same code unit.
Mark Dickinson105be772008-01-31 22:17:37 +00003431
Georg Brandl3ee81df2008-05-17 18:14:43 +00003432- Issue #2025: Add tuple.count() and tuple.index() methods to comply
3433 with the collections.Sequence API.
Raymond Hettinger5b07ebc2008-02-07 00:54:20 +00003434
Georg Brandl3ee81df2008-05-17 18:14:43 +00003435- Patch #1970 by Antoine Pitrou: Speedup unicode whitespace and
3436 linebreak detection
Christian Heimes4d4f2702008-01-30 11:32:37 +00003437
Georg Brandl3ee81df2008-05-17 18:14:43 +00003438- Added ``PyType_ClearCache()`` and ``sys._clear_type_cache`` to clear
3439 the internal lookup cache for ref leak tests.
Christian Heimes908caac2008-01-27 23:34:59 +00003440
Georg Brandl3ee81df2008-05-17 18:14:43 +00003441- Patch #1473257: generator objects gain a gi_code attribute. This is
3442 the same object as the func_code attribute of the function that
3443 produced the generator.
Georg Brandl0cdf9a32008-01-26 14:14:20 +00003444
Georg Brandl3ee81df2008-05-17 18:14:43 +00003445- Issue #1920: "while 0" statements were completely removed by the
3446 compiler, even in the presence of an "else" clause, which is
3447 supposed to be run when the condition is false. Now the compiler
3448 correctly emits bytecode for the "else" suite.
Amaury Forgeot d'Arc31eaafe2008-01-24 22:59:25 +00003449
Guido van Rossumeead05f2008-01-24 18:21:02 +00003450- A few crashers fixed: weakref_in_del.py (issue #1377858);
3451 loosing_dict_ref.py (issue #1303614, test67.py);
3452 borrowed_ref_[34].py (not in tracker).
3453
Vinay Sajipd7cf32e2008-01-24 12:43:33 +00003454- Issue #1069410: The "can't load dll" message box on Windows is
Christian Heimesb2302ba2008-01-23 17:15:06 +00003455 suppressed while an extension is loaded by calling SetErrorMode in
3456 dynload_win.c. The error is still reported properly.
3457
Georg Brandl3ee81df2008-05-17 18:14:43 +00003458- Issue #1915: Python compiles with --enable-unicode=no again. However
Christian Heimes082c9b02008-01-23 14:20:50 +00003459 several extension methods and modules do not work without unicode
3460 support.
3461
Georg Brandl26543b12008-01-21 18:36:51 +00003462- Issue #1882: when compiling code from a string, encoding cookies in the
3463 second line of code were not always recognized correctly.
3464
Georg Brandl14404b62008-01-19 19:27:05 +00003465- Issue #1679: "0x" was taken as a valid integer literal.
3466
Georg Brandl6caad7d2008-01-26 14:19:22 +00003467- Issue #1865: ``bytes`` as an alias for ``str`` and b"" as an alias "" were
Christian Heimes288e89a2008-01-18 18:24:07 +00003468 added.
3469
Christian Heimesc94e2b52008-01-14 04:13:37 +00003470- sys.float_info / PyFloat_GetInfo: The floating point information
3471 object was converted from a dict to a specialized structseq object.
3472
Georg Brandl3ee81df2008-05-17 18:14:43 +00003473- Patch #1816: Added sys.flags structseq. It exposes the status of
3474 most command line arguments and PYTHON* environment variables.
Christian Heimesf31b69f2008-01-14 03:42:48 +00003475
Georg Brandl3ee81df2008-05-17 18:14:43 +00003476- Objects/structseq.c: Implemented new structseq representation. The
3477 patch makes structseqs (e.g. the return value of os.stat) more
3478 readable.
Christian Heimes9c201962008-01-14 03:33:52 +00003479
Georg Brandl3ee81df2008-05-17 18:14:43 +00003480- Patch #1700288: added a type attribute cache that caches method
3481 accesses, resulting in speedups in heavily object-oriented code.
Amaury Forgeot d'Arce4c270c2008-01-14 00:29:41 +00003482
Neal Norwitz3fc15b82008-01-10 05:42:58 +00003483- Bug #1776: __import__() no longer accepts filenames on any platform.
3484 The first parameter to __import__() must be a valid module name.
Christian Heimes3403f152008-01-09 19:56:33 +00003485

3487
Georg Brandl3ee81df2008-05-17 18:14:43 +00003488- Patch #602345: Add -B command line option, PYTHONDONTWRITEBYTECODE
3489 envvar and sys.dont_write_bytecode attribute. All these can be set
3490 to forbid Python to attempt to write compiled bytecode files.
Georg Brandl2da0fce2008-01-07 17:09:35 +00003491
Georg Brandl3ee81df2008-05-17 18:14:43 +00003492- Improve some exception messages when Windows fails to load an
3493 extension module. Now we get for example '%1 is not a valid Win32
3494 application' instead of 'error code 193'.
Amaury Forgeot d'Arce0b76952008-01-04 02:04:15 +00003495
Georg Brandl3ee81df2008-05-17 18:14:43 +00003496- Bug #1481296: Fixed long(float('nan')) != 0L.

Georg Brandl3ee81df2008-05-17 18:14:43 +00003498- Issue #1640: Added math.isinf(x), math.isnan(x) and math.copysign(x,
3499 y) functions.
Christian Heimese2ca4242008-01-03 20:23:15 +00003500
Christian Heimes0a8143f2007-12-18 23:22:54 +00003501- Issue #1635: Platform independent creation and representation of NaN
Georg Brandl3ee81df2008-05-17 18:14:43 +00003502 and INF. float("nan"), float("inf") and float("-inf") now work on
3503 every platform with IEEE 754 semantics.
Christian Heimes0a8143f2007-12-18 23:22:54 +00003504
Georg Brandl3ee81df2008-05-17 18:14:43 +00003505- Compiler now generates simpler and faster code for dictionary
3506 literals. The oparg for BUILD_MAP now indicates an estimated
3507 dictionary size. There is a new opcode, STORE_MAP, for adding
3508 entries to the dictionary.
Raymond Hettingerfd7ed402007-12-18 21:24:09 +00003509
Georg Brandl3ee81df2008-05-17 18:14:43 +00003510- Issue #1638: %zd configure test fails on Linux.

3538 file can now be directly executed by passing their name to the
3539 interpreter. The directory/zipfile is automatically inserted as the
3540 first entry in sys.path.
Nick Coghlan327a39b2007-11-18 11:56:28 +00003541
Georg Brandl3ee81df2008-05-17 18:14:43 +00003542- Issue #1265: Fix a problem with sys.settrace, if the tracing
3543 function uses a generator expression when at the same time the
3544 executed code is closing a paused generator.
Amaury Forgeot d'Arc0d75f092007-11-13 21:54:28 +00003545
Raymond Hettinger1760c8a2007-11-08 02:52:43 +00003546- sets and frozensets now have an isdisjoint() method.
3547
Raymond Hettinger3f8caa32007-10-24 01:28:33 +00003548- optimize the performance of builtin.sum().
3549
Neal Norwitz44f326e2007-10-05 05:29:17 +00003550- Fix warnings found by the new version of the Coverity checker.
3551
Georg Brandl3ee81df2008-05-17 18:14:43 +00003552- The enumerate() builtin function is no longer bounded to sequences
3553 smaller than LONG_MAX. Formerly, it raised an OverflowError. Now,
3554 automatically shifts from ints to longs.
Raymond Hettinger8f669372007-10-03 21:18:11 +00003555
Georg Brandl3ee81df2008-05-17 18:14:43 +00003556- Issue #1686386: Tuple's tp_repr did not take into account the
3557 possibility of having a self-referential tuple, which is possible
3558 from C code. Nor did object's tp_str consider that a type's tp_str
3559 could do something that could lead to an inifinite recursion.
3560 Py_ReprEnter() and Py_EnterRecursiveCall(), respectively, fixed the
3561 issues.
Brett Cannon0b14f242007-09-30 19:45:10 +00003562
Georg Brandl3ee81df2008-05-17 18:14:43 +00003563- Issue #1164: It was possible to trigger deadlock when using the
3564 'print' statement to write to a file since the GIL was not released
3565 as needed. Now PyObject_Print() does the right thing along with
3566 various tp_print implementations of the built-in types and those in
3567 the collections module.
Brett Cannon01531592007-09-17 03:28:34 +00003568
Georg Brandl3ee81df2008-05-17 18:14:43 +00003569- Issue #1147: Exceptions were directly allowing string exceptions in
3570 their throw() method even though string exceptions no longer
3571 allowed.
Brett Cannon4c20bc42007-09-11 21:02:28 +00003572
Georg Brandl3ee81df2008-05-17 18:14:43 +00003573- Issue #1096: Prevent a segfault from getting the repr of a very

Brett Cannon1e534b52007-09-07 04:18:30 +00003576- Issue #1202533: Fix infinite recursion calls triggered by calls to
Georg Brandl3ee81df2008-05-17 18:14:43 +00003577 PyObject_Call() never calling back out to Python code to trigger
3578 recursion depth updates/checks. Required the creation of a static
3579 RuntimeError instance in case normalizing an exception put the
3580 recursion check value past its limit. Fixes crashers
3581 infinite_rec_(1|2|4|5).py.
Brett Cannon1e534b52007-09-07 04:18:30 +00003582
Georg Brandl3ee81df2008-05-17 18:14:43 +00003583- Patch #1031213: Decode source line in SyntaxErrors back to its

Neal Norwitz0ac60192007-05-27 04:08:54 +00003596- Add new attribute names for function objects. All the func_* become
Georg Brandl3ee81df2008-05-17 18:14:43 +00003597 __*__ attributes. (Some already existed, e.g., __doc__ and
3598 __name__.)
Neal Norwitz0ac60192007-05-27 04:08:54 +00003599
Neal Norwitz8b2bfbc2007-05-23 06:35:32 +00003600- Add -3 option to the interpreter to warn about features that are
3601 deprecated and will be changed/removed in Python 3.0.
3602
Georg Brandl2134e752007-05-21 20:34:16 +00003603- Patch #1686487: you can now pass any mapping after '**' in function
3604 calls.
3605
Collin Winter62903052007-05-18 23:11:24 +00003606- except clauses may now be spelled either "except E, target:" or
Georg Brandl3ee81df2008-05-17 18:14:43 +00003607 "except E as target:". This is to provide forwards compatibility

Brett Cannon229cee22007-05-05 01:34:02 +00003610- Deprecate BaseException.message as per PEP 352.
3611
Georg Brandl3ee81df2008-05-17 18:14:43 +00003612- Issue #1303614: don't expose object's __dict__ when the dict is
Armin Rigo9790a272007-05-02 19:23:31 +00003613 inherited from a builtin base.
3614
Vinay Sajip8549ce32007-05-06 17:53:37 +00003615- When __slots__ are set to a unicode string, make it work the same as
Neal Norwitzcbd9ee62007-04-14 05:25:50 +00003616 setting a plain string, ie don't expand to single letter identifiers.
3617
Raymond Hettinger13936692007-04-11 18:40:58 +00003618- Request #1191699: Slices can now be pickled.
3619
Raymond Hettinger4db5fe92007-04-12 04:10:00 +00003620- Request #1193128: str.translate() now allows a None argument for
3621 translations that only remove characters without re-mapping the
3622 remaining characters.
3623
Georg Brandl5cb76c12007-03-21 09:00:39 +00003624- Patch #1682205: a TypeError while unpacking an iterable is no longer
3625 masked by a generic one with the message "unpack non-sequence".
3626

3628
Guido van Rossum143b5642007-03-23 04:58:42 +00003629- Bug #1683368: The object.__init__() and object.__new__() methods are
3630 now stricter in rejecting excess arguments. The only time when
3631 either allows excess arguments is when it is not overridden and the
3632 other one is. For backwards compatibility, when both are
3633 overridden, it is a deprecation warning (for now; maybe a Py3k
Guido van Rossum234b1ff2007-03-23 19:39:01 +00003634 warning later). Also, type.__init__() insists on the same signature
3635 as supported by type.__new__().
Guido van Rossum143b5642007-03-23 04:58:42 +00003636
Georg Brandl3ee81df2008-05-17 18:14:43 +00003637- Patch #1675423: PyComplex_AsCComplex() now tries to convert an
3638 object to complex using its __complex__() method before falling back
3639 to the __float__() method. Therefore, the functions in the cmath
3640 module now can operate on objects that define a __complex__()
3641 method.

3645 same slot names.

3658
Georg Brandl7b9c5552007-03-12 14:30:05 +00003659- Bug #1678647: write a newline after printing an exception in any
3660 case, even when converting the value to a string failed.
3661
Georg Brandl871f1bc2007-03-12 13:17:36 +00003662- The dir() function has been extended to call the __dir__() method on
Georg Brandl3ee81df2008-05-17 18:14:43 +00003663 its argument, if it exists. If not, it will work like before. This
3664 allows customizing the output of dir() in the presence of a
3665 __getattr__().
Georg Brandl871f1bc2007-03-12 13:17:36 +00003666
Collin Winter276887b2007-03-12 16:11:39 +00003667- Patch #922167: Python no longer segfaults when faced with infinitely
3668 self-recursive reload() calls (as reported by bug #742342).

3674 parthensized forms. This means complex(repr(x)) now works instead of
3675 raising a ValueError.
Collin Wintere38051d2007-03-09 20:33:07 +00003676
Georg Brandlaa2321b2007-03-07 00:40:28 +00003677- Patch #703779: unset __file__ in __main__ after running a file. This
Georg Brandl3ee81df2008-05-17 18:14:43 +00003678 makes the filenames the warning module prints much more sensible
3679 when a PYTHONSTARTUP file is used.
Georg Brandlaa2321b2007-03-07 00:40:28 +00003680

Georg Brandl0fca97a2007-03-05 22:28:08 +00003692- Patch #1674228: when assigning a slice (old-style), check for the
3693 sq_ass_slice instead of the sq_slice slot.
3694
Georg Brandl3ee81df2008-05-17 18:14:43 +00003695- When printing an unraisable error, don't print exceptions. before
3696 the name. This duplicates the behavior whening normally printing
3697 exceptions.

3706 created a weakref on itself during a __del__ call for new-style
3707 classes (classic classes still have the bug).

Georg Brandl2c1375c2006-10-12 11:27:59 +00003747- Bug #1545497: when given an explicit base, int() did ignore NULs
3748 embedded in the string to convert.
3749
Georg Brandl846f73a2006-10-08 07:11:54 +00003750- Bug #1569998: break inside a try statement (outside a loop) is now

Georg Brandl3ee81df2008-05-17 18:14:43 +00003798 generator expressions (x for x, in ... ) works again. Fixing this
3799 problem required changing the .pyc magic number. This means that
3800 .pyc files generated before 2.5c2 will be regenerated.

Georg Brandl3ee81df2008-05-17 18:14:43 +00004607- Issue #829951: In the smtplib module, SMTP.starttls() now complies
4608 with RFC 3207 and forgets any knowledge obtained from the server not
4609 obtained from the TLS negotiation itself. Patch contributed by Bill
4610 Fenner.
Gregory P. Smith2b3ba582008-01-17 08:03:17 +00004611
Georg Brandl3ee81df2008-05-17 18:14:43 +00004612- Issue #1339: The smtplib.SMTP class has been refactored a bit such
Gregory P. Smithbde4ae42008-01-17 08:35:49 +00004613 that the SMTP.starttls() caller no longer needs to call ehlo()
4614 beforehand. SMTP.starttls() now raises an exception of the server
Georg Brandl3ee81df2008-05-17 18:14:43 +00004615 does not claim to support starttls. Adds the
4616 SMTP.ehlo_or_helo_if_needed() method. Patch contributed by Bill
4617 Fenner.

4697 complex, tuple, list, dict, set, and frozenset. Formerly, it would
4698 silently miscode subclasses of those types. Now, it raises a

Georg Brandl3ee81df2008-05-17 18:14:43 +00004715 time so that opening a database previously created with the DB_DUP
4716 or DB_DUPSORT flag set will keep the proper behavior on subsequent
4717 opens. Specifically: dictionary assignment to a DB object will
4718 replace all values for a given key when the database allows
4719 duplicate values. DB users should use DB.put(k, v) when they want
4720 to store duplicates; not DB[k] = v.
Gregory P. Smithec10a4a2007-11-05 02:32:26 +00004721

4727 characters with ASCII value less than 32. Also, it correctly quotes
4728 dots only if they occur on a single line, as opposed to the previous
4729 behavior of quoting dots if they are the second character of any
4730 line.
Georg Brandl4aef7272007-03-13 22:49:43 +00004731

Georg Brandl3ee81df2008-05-17 18:14:43 +00005136- Removed the macfs module. It had been deprecated since Python 2.5.
5137 This lead to the deprecation of macostools.touched() as it relied
5138 solely on macfs and was a no-op under OS X.
