32Core and Builtins
33-----------------
34
Benjamin Petersonecdae192010-01-04 00:43:01 +000035- The __complex__ method is now looked up on the class of instances to make it
36 consistent with other special methods.
37
Antoine Pitrou5b7139a2010-01-02 21:12:58 +000038- Issue #7462: Implement the stringlib fast search algorithm for the `rfind`,
39 `rindex`, `rsplit` and `rpartition` methods. Patch by Florent Xicluna.
40
Mark Dickinson1b34d252010-01-01 17:27:30 +000041- Issue #5080: A number of functions and methods previously produced a
42 DeprecationWarning when passed a float argument where an integer was
43 expected. These functions and methods now raise TypeError instead.
44 The majority of the effects of this change are in the extension
45 modules, but some core functions and methods are affected: notably
46 the 'chr', 'range' and 'xrange' builtins, and many unicode/str
47 methods.
48
Benjamin Peterson0f02d392009-12-30 19:34:10 +000049- Issue #7604: Deleting an unset slotted attribute did not raise an
50 AttributeError.
51
Mark Dickinson99d652e2009-12-30 12:12:23 +000052- Issue #7534: Fix handling of IEEE specials (infinities, nans,
53 negative zero) in ** operator. The behaviour now conforms to that
54 described in C99 Annex F.
55
Amaury Forgeot d'Arcc8a2ce72009-12-29 23:06:17 +000056- Issue #7579: the msvcrt module now has docstrings for all its functions.
57
Amaury Forgeot d'Arc8645a5c2009-12-29 22:03:38 +000058- Issue #7413: Passing '\0' as the separator to datetime.datetime.isoformat()
59 used to drop the time part of the result.
60
Mark Dickinson46572832009-12-27 14:55:57 +000061- Issue #1811: improve accuracy and cross-platform consistency for
62 true division of integers: the result of a/b is now correctly
63 rounded for ints a and b (at least on IEEE 754 platforms), and in
64 particular does not depend on the internal representation of a long.
65
Ezio Melottif84caf42009-12-24 22:25:17 +000066- Issue #6108: unicode(exception) and str(exception) should return the same
67 message when only __str__ (and not __unicode__) is overridden in the subclass.
68
Ronald Oussoren92919a62009-12-24 13:30:58 +000069- Issue #6834: replace the implementation for the 'python' and 'pythonw'
70 executables on OSX.
71
72 These executables now work properly with the arch(1) command:
73 ``arch -ppc python`` will start a universal binary version of python
74 in PPC mode (unlike previous releases).
75
R. David Murray0a0a1a82009-12-14 16:28:26 +000076- Issue #1680159: unicode coercion during an 'in' operation no longer masks
77 the underlying error when the coercion fails for the left hand operand.
78
Benjamin Peterson4895af42009-12-13 16:36:53 +000079- Issue #7491: Metaclass's __cmp__ method was ignored.

89 gcc when it has a fully qualified configuration prefix. Initial patch
90 by Arfrever.
91
Antoine Pitrou80157252010-01-08 19:20:17 +000092- Issue #7092: Remove py3k warning when importing cPickle. 2to3 handles
93 renaming of `cPickle` to `pickle`. The warning was annoying since there's
94 no alternative to cPickle if you care about performance. Patch by Florent
95 Xicluna.
96
Antoine Pitrou0d423b82010-01-07 17:46:49 +000097- Issue #7455: Fix possible crash in cPickle on invalid input. Patch by

Antoine Pitrou673ddf92010-01-03 22:29:56 +0000103- Issue #7471: Improve the performance of GzipFile's buffering mechanism,
104 and make it implement the `io.BufferedIOBase` ABC to allow for further
105 speedups by wrapping it in an `io.BufferedReader`. Patch by Nir Aides.
106
107- Issue #3972: httplib.HTTPConnection now accepts an optional source_address
Gregory P. Smith9d325212010-01-03 02:06:07 +0000108 parameter to allow specifying where your connections come from.

Senthil Kumaran7713acf2009-12-20 06:05:13 +0000126 Patch by Tatsuhiro Tsujikawa.
127
Benjamin Petersonddd392c2009-12-13 19:19:07 +0000128- Issue #7349: Make methods of file objects in the io module accept None as an
129 argument where file-like objects (ie StringIO and BytesIO) accept them to mean
130 the same as passing no argument.
131
Benjamin Petersonc4771d22009-12-13 17:31:31 +0000132- Issue #7348: StringIO.StringIO.readline(-1) now acts as if it got no argument
133 like other file objects.
134

141 missing proper end-of-line termination.
142
Tarek Ziadé2421d562009-12-20 23:23:34 +0000143- Issue #7457: added a read_pkg_file method to

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

201-----------------
202
Amaury Forgeot d'Arcd7288712009-12-01 21:51:04 +0000203- Issue #7419: setlocale() could crash the interpreter on Windows when called
204 with invalid values.
205
Eric Smithc4ab8332009-11-29 17:40:57 +0000206- Issue #3382: 'F' formatting for float and complex now convert the
207 result to upper case. This only affects 'inf' and 'nan', since 'f'
208 no longer converts to 'g' for large values.
Amaury Forgeot d'Arcd7288712009-12-01 21:51:04 +0000209
Mark Dickinson9dd5e162009-11-23 20:54:09 +0000210- Remove switch from "%f" formatting to "%g" formatting for floats
211 larger than 1e50 in absolute value.
212
Mark Dickinson18cfada2009-11-23 18:46:41 +0000213- Remove restrictions on precision when formatting floats. E.g.,
214 "%.120g" % 1e-100 used to raise OverflowError, but now gives the
215 requested 120 significant digits instead.
216
Benjamin Peterson89b1a5c2009-11-19 22:58:01 +0000217- Add Py3k warnings for parameter names in parenthesis.
218
Benjamin Peterson48f0a8d2009-11-19 23:19:29 +0000219- Issue #7362: Give a proper error message for def f((x)=3): pass.
Benjamin Peterson89b1a5c2009-11-19 22:58:01 +0000220
Ronald Oussoren315cd0c2009-11-19 16:25:21 +0000221- Issue #7085: Fix crash when importing some extensions in a thread
222 on MacOSX 10.6.
223
Mark Dickinsonb678de82009-11-19 18:41:49 +0000224- Issue #7117: repr(x) for a float x returns a result based on the
225 shortest decimal string that's guaranteed to round back to x under
226 correct rounding (with round-half-to-even rounding mode).
227 Previously it gave a string based on rounding x to 17 decimal digits.
228 repr(x) for a complex number behaves similarly. On platforms where
229 the correctly-rounded strtod and dtoa code is not supported (see below),
230 repr is unchanged.
231
232- Issue #7117: On almost all platforms: float-to-string and
233 string-to-float conversions within Python are now correctly rounded.
234 Places these conversions occur include: str for floats and complex
235 numbers; the float and complex constructors; old-style and new-style
236 numeric formatting; serialization and deserialization of floats and
237 complex numbers using marshal, pickle and json; parsing of float and
238 imaginary literals in Python code; Decimal-to-float conversion.
239
240 The conversions use a Python-adapted version of David Gay's
241 well-known dtoa.c, providing correctly-rounded strtod and dtoa C
242 functions. This code is supported on Windows, and on Unix-like
243 platforms using gcc, icc or suncc as the C compiler. There may be a
244 small number of platforms on which correct operation of this code
245 cannot be guaranteed, so the code is not used: notably, this applies
246 to platforms where the C double format is not IEEE 754 binary64, and
247 to platforms on x86 hardware where the x87 FPU is set to 64-bit
248 precision and Python's configure script is unable to determine how
249 to change the FPU precision. On these platforms conversions use the
250 platform strtod and dtoa, as before.
251
Mark Dickinsonbd15a062009-11-18 19:33:35 +0000252- Issue #7117: Backport round implementation from Python 3.x. round
Mark Dickinsonb678de82009-11-19 18:41:49 +0000253 now uses the correctly-rounded string <-> float conversions
254 described above (when available), and so produces correctly rounded
255 results that will display nicely under the float repr. There are
256 two related small changes: (1) round now accepts any class with an
257 __index__ method for its second argument (but no longer accepts
Mark Dickinsonbd15a062009-11-18 19:33:35 +0000258 floats for the second argument), and (2) an excessively large second
259 integer argument (e.g., round(1.234, 10**100)) no longer raises an
260 exception.
261
Philip Jenveyfab8be22009-11-17 02:42:26 +0000262- Issue #1757126: Fix the cyrillic-asian alias for the ptcp154 encoding.
263
Benjamin Petersone36199b2009-11-12 23:39:44 +0000264- Fix several issues with compile(). The input can now contain Windows and Mac
265 newlines and is no longer required to end in a newline.
266
Mark Dickinsonc04c7c52009-10-26 22:28:14 +0000267- Remove length limitation when constructing a complex number from a
268 unicode string.
269
Raymond Hettingerfa7dadd2009-11-01 20:45:16 +0000270- Issue #7244: itertools.izip_longest() no longer ignores exceptions
271 raised during the formation of an output tuple.
272

294
Amaury Forgeot d'Arcd0052d12009-10-06 19:56:32 +0000295- Issue #1571184: The Unicode database contains properties for more characters.

308 of producing internally inconsistent Python longs.
309
Philip Jenveydbf3b252009-09-29 04:32:44 +0000310- Issue #6990: Fix threading.local subclasses leaving old state around

390
Mark Dickinsona4e0efa2009-05-20 18:43:07 +0000391- Issue #5829: complex("1e500") no longer raises OverflowError. This

Mark Dickinsonb1d45852009-05-11 15:33:08 +0000402- Issue #5981: Fix three minor inf/nan issues in float.fromhex:
403 (1) inf and nan strings with trailing whitespace were incorrectly

405 was locale aware; and (3) the interpretation of fromhex('-nan')
406 didn't match that of float('-nan').
407
Eric Smitha985a3a2009-05-05 18:26:08 +0000408- Issue #5920: For float.__format__, change the behavior with the
409 empty presentation type (that is, not one of 'e', 'f', 'g', or 'n')
410 to be like 'g' but with at least one decimal point and with a
411 default precision of 12. Previously, the behavior the same but with
412 a default precision of 6. This more closely matches str(), and
413 reduces surprises when adding alignment flags to the empty
414 presentation type. This also affects the new complex.__format__ in
415 the same way.
416
R. David Murray7ba8e1c2009-05-04 22:16:24 +0000417- Issue #5890: in subclasses of 'property' the __doc__ attribute was

481 reduce the size of collections and therefore the garbage collection overhead
482 on long-running programs, depending on their particular use of datatypes.
483
Mark Dickinson0b666bf2009-03-23 18:25:13 +0000484- Issue #5512: Rewrite PyLong long division algorithm (x_divrem) to

489 2**15 for the internal representation of integers, for performance
490 reasons. Base 2**30 is enabled by default on 64-bit machines. Add

517 on a 64-bit system.
518
Antoine Pitrou76a4b892009-02-13 13:52:33 +0000519- Issue #5186: Reduce hash collisions for objects with no __hash__ method by

526
Georg Brandl29c6a282009-04-05 20:23:13 +0000527- Issue #1242657: the __len__() and __length_hint__() calls in several tools
Raymond Hettingerb5163702009-02-02 21:50:13 +0000528 were suppressing all exceptions. These include list(), filter(), map(),

603 "offsetof(PyStringObject, ob_sval) + 1" when allocating memory for
604 str instances. On a typical machine this saves 3 bytes of memory
605 (on average) per string allocation.
606
Amaury Forgeot d'Arcdc619012008-11-22 20:01:18 +0000607- Issue #3996: On Windows, the PyOS_CheckStack function would cause the
608 interpreter to abort ("Fatal Python error: Could not reset the stack!")
609 instead of throwing a MemoryError.
610
Raymond Hettinger7989a4d2008-12-03 15:42:10 +0000611- Issue #3689: The list reversed iterator now supports __length_hint__

Vinay Sajip213faca2008-12-03 23:22:58 +0000617- Issue #4233: Changed semantic of ``_fileio.FileIO``'s ``close()``
Amaury Forgeot d'Arc32265652008-11-20 23:34:31 +0000618 method on file objects with closefd=False. The file descriptor is still
619 kept open but the file object behaves like a closed file. The ``FileIO``
620 object also got a new readonly attribute ``closefd``.
621
Benjamin Peterson46cc6d12008-11-19 21:49:09 +0000622- Issue #4348: Some bytearray methods returned that didn't cause any change to

Hirokazu Yamamoto10a018c2008-10-09 10:00:30 +0000643- On windows, os.chdir given unicode was not working if GetCurrentDirectoryW
644 returned a path longer than MAX_PATH. (But It's doubtful this code path is
645 really executed because I cannot move to such directory on win2k)
646
Amaury Forgeot d'Arcd78b9dc2008-10-07 20:32:10 +0000647- Issue #4069: When set.remove(element) is used with a set element, the element
648 is temporarily replaced with an equivalent frozenset. But the eventual
649 KeyError would always report the empty frozenset([]) as the missing key. Now
650 it correctly refers to the initial element.

668 returned them on 64bit platforms.
669
Walter Dörwalded960ac2009-05-03 22:36:33 +0000670- Issue #5108: Handle %s like %S and %R in PyUnicode_FromFormatV(): Call
671 PyUnicode_DecodeUTF8() once, remember the result and output it in a second
672 step. This avoids problems with counting UTF-8 bytes that ignores the effect
673 of using the replace error handler in PyUnicode_DecodeUTF8().
674
Walter Dörwald726ba8e2009-05-06 14:32:35 +0000675- Issue #3739: The unicode-internal encoder now reports the number of characters
676 consumed like any other encoder (instead of the number of bytes).
677
Benjamin Peterson91c12eb2009-12-03 02:52:39 +0000678- Issue #2422: When compiled with the ``--with-valgrind`` option, the
679 pymalloc allocator will be automatically disabled when running under
680 Valgrind. This gives improved memory leak detection when running
681 under Valgrind, while taking advantage of pymalloc at other times.

Martin v. Löwis9fa5a282008-09-11 06:53:30 +00002061- Issue #3642: Suppress warning in obmalloc when size_t is larger than uint.
2062
Amaury Forgeot d'Arc05e34492008-09-10 22:04:45 +00002063- Issue #3743: In a few places, PY_FORMAT_SIZE_T was incorrectly used with
2064 PyString_FromFormat or PyErr_Format to display size_t values. The macro
2065 PY_FORMAT_SIZE_T is designed to select the correct format for the OS
2066 ``printf`` function, whereas PyString_FromFormat has an independent
2067 implementation and uses "%zd" on all platforms for size_t values.
2068 This makes a difference on win64, where ``printf`` needs "%Id" to display
2069 64bit values.

Benjamin Peterson97179b02008-09-09 20:55:01 +00002071- Issue #3634: _weakref.ref(Exception).__init__() gave invalid return value on

2075 object; previously an int would be returned for small values. the __long__
2076 method is allowed to return either an int or a long, but the behaviour of
2077 float objects should not change to respect backward compatibility.
2078
Amaury Forgeot d'Arc3571fbf2008-09-01 19:52:00 +00002079- Issue #3751: str.rpartition would perform a left-partition when called with
2080 a unicode argument.

Vinay Sajip35e3b032008-09-01 14:33:59 +00002085 PyArg_ParseTuple and friends, which occurred when the argument for "s*"
Antoine Pitroud4ae97b2008-08-29 18:39:48 +00002086 was correctly parsed but parsing of subsequent arguments failed.
2087
Vinay Sajip35e3b032008-09-01 14:33:59 +00002088- Issue #2534: speed up isinstance() and issubclass() by 50-70%, so as to
Antoine Pitrou0668c622008-08-26 22:42:08 +00002089 match Python 2.5 speed despite the __instancecheck__ / __subclasscheck__
2090 mechanism. In the process, fix a bug where isinstance() and issubclass(),
2091 when given a tuple of classes as second argument, were looking up
2092 __instancecheck__ / __subclasscheck__ on the tuple rather than on each
2093 type object.
2094
Neal Norwitz18aa3882008-08-24 05:04:52 +00002095- Fix crashes on memory allocation failure found with failmalloc.

2238-----------------
2239
Guido van Rossumf8402962008-08-20 15:01:50 +00002240- Issue #1878: Remove Py_TPFLAGS_HAVE_VERSION_TAG from
2241 Py_TPFLAGS_DEFAULT when not building the core. This means 3rd party
2242 extensions do not automatically benefit from the class attribute
2243 cache; they will have to explicitly add Py_TPFLAGS_HAVE_VERSION_TAG
2244 to their tp_flags field if they care. This is a backwards
2245 compatibility feature; in 3.0, all types will use the cache by
2246 default.
2247
Benjamin Petersonf647dc12008-08-20 01:27:30 +00002248- Keyword arguments can now follow starred arguments. (``f(a, *args,
2249 keyword=23)`` is now valid syntax.)
2250
Thomas Heller0ad5ae02008-08-19 19:25:04 +00002251- ctypes function pointers that are COM methods have a boolean True
2252 value again.
2253
Martin v. Löwisf91d46a2008-08-12 14:49:50 +00002254- Issue #3139: Make buffer-interface thread-safe wrt. PyArg_ParseTuple,
2255 by denying s# to parse objects that have a releasebuffer procedure,
2256 and introducing s*.
2257
Georg Brandl1e13ea92008-08-11 09:07:59 +00002258- Issue #3537: Fix an assertion failure when an empty but presized dict
2259 object was stored in the freelist.

Mark Dickinsonb6467572008-08-04 21:30:09 +00002261- Issue #1481296: Make long(float('nan')) and int(float('nan')) raise
2262 ValueError consistently across platforms.
2263
Amaury Forgeot d'Arc39fd6722008-07-31 21:28:03 +00002264- Issue #3479: On platforms where sizeof(int) is smaller than sizeof(long)
2265 (64bit Unix, for example), unichr() would truncate its argument and return
2266 u'\x00' for unichr(2**32). Now it properly raises an OverflowError.
2267
Neal Norwitze7d8be82008-07-31 17:17:14 +00002268- Apply security patches from Apple.

Antoine Pitrou92f82162008-07-25 22:22:08 +00002273- Issue #1819: function calls with several named parameters are now on
2274 average 35% faster (as measured by pybench).
2275
Amaury Forgeot d'Arce4921fe2008-07-21 22:00:38 +00002276- Issue #2378: An unexpected UnboundLocalError or NameError could appear when
2277 the python debugger steps into a class statement: the free variables (local
2278 variables defined in an outer scope) would be deleted from the outer scope.
2279
Gregory P. Smith0470bab2008-07-22 04:46:32 +00002280- Issue #2620: Overflow checking when allocating or reallocating memory
2281 was not always being done properly in some python types and extension
2282 modules. PyMem_MALLOC, PyMem_REALLOC, PyMem_NEW and PyMem_RESIZE have
2283 all been updated to perform better checks and places in the code that
2284 would previously leak memory on the error path when such an allocation
2285 failed have been fixed.

2291
Benjamin Petersone977ad42008-08-20 01:42:01 +00002292- The methods ``is_in_tuple()``, ``is_vararg()``, and ``is_keywordarg()`` of
2293 symtable.Symbol have been deprecated for removal in 3.0 and the next release.
2294
Amaury Forgeot d'Arc351ffb82008-08-18 19:23:47 +00002295- Issue #2234: distutils failed for some versions of the cygwin compiler. The
2296 version reported by these tools does not necessarily follow the python
2297 version numbering scheme, so the module is less strict when parsing it.
2298
Nick Coghlanf70385a2008-08-18 12:42:46 +00002299- Issue #2235: Added Py3k warnings for types which will become unhashable
2300 under the stricter __hash__ inheritance rules in 3.0. Several types
2301 which did not meet the rules for hash invariants and were already
2302 unhashable in 3.0 have now been explicitly flagged as unhashable in
2303 2.6 as well (collections.Mapping, collections.Set, unittest.TestSuite,
2304 xml.dom.minidom.NamedNodeMap, numbers.Number, UserList.UserList)
2305
Brett Cannon88f801d2008-08-18 00:46:22 +00002306- Update __all__ for cookielib, csv, os, urllib2, and weakref to include things
2307 imported into the module but exposed as part of the module's API.
2308

Hirokazu Yamamoto41a81eb2008-08-17 13:10:46 +00002315- Issue #3575: Incremental decoder's decode function now takes bytearray
2316 by using 's*' instead of 't#'.
2317
Mark Dickinson3e4caeb2009-02-21 20:27:01 +00002318- Issue #2222: Fixed reference leak when occurred os.rename()
Hirokazu Yamamoto7f30a682008-08-17 09:46:56 +00002319 fails unicode conversion on 2nd parameter. (windows only)
2320
Facundo Batista94f243a2008-08-17 03:38:39 +00002321- Issue 2464. urllib2 now supports a malformation in the URL received
2322 in a redirect.

Facundo Batistaeb90b782008-08-16 14:44:07 +00002327- Issue #2776: fixed small issue when handling an URL with double slash
2328 after a 302 response in the case of not going through a proxy.
2329
Antoine Pitroub90a8be2008-08-15 21:03:21 +00002330- Issue #2676: in the email package, content-type parsing was hanging on
2331 pathological input because of quadratic or exponential behaviour of a
2332 regular expression.
2333
Antoine Pitrou11ec65d2008-08-14 21:04:30 +00002334- Issue #3476: binary buffered reading through the new "io" library is now
2335 thread-safe.
2336
Brett Cannonbf3157b2008-08-14 05:00:03 +00002337- Silence the DeprecationWarning of rfc822 when it is imported by mimetools
2338 since mimetools itself is deprecated. Because modules are cached, all
2339 subsequent imports of rfc822 will not raise a visible DeprecationWarning.
2340
Antoine Pitrou9fcd4b32008-08-11 17:21:36 +00002341- Issue #3134: shutil referenced undefined WindowsError symbol.

Robert Schuppenies14646332008-08-10 11:01:53 +00002343- Issue #1342811: Fix leak in Tkinter.Menu.delete. Commands associated to
2344 menu entries were not deleted.
2345
Brett Cannon83e81842008-08-09 23:30:55 +00002346- Copied the implementation of reduce() to _functools.reduce() to have a
2347 version that did not raise a DeprecationWarning under -3.
2348
Antoine Pitrou76b8bee2008-08-09 17:27:23 +00002349- Issue #3205: When iterating over a BZ2File fails allocating memory, raise
2350 a MemoryError rather than silently stop the iteration.
2351
Guido van Rossum59ce9012008-08-09 14:55:34 +00002352- Issue #3487: sre "bytecode" validator. Passing invalid "re-bytecode"
2353 to _sre.compile() will now be rejected. This should not affect anybody
2354 since the re.compile() function never generates invalid re-bytecode.
2355
Skip Montanaroa032bf42008-08-08 22:52:51 +00002356- Issue #3436: Make csv.DictReader's fieldnames attribute a property so that
2357 upon first access it can be automatically initialized from the csv file if
2358 it wasn't initialized during instantiation.
2359
Brett Cannon3aa2a492008-08-06 22:28:09 +00002360- Issue #2338: Create imp.reload() to help with transitioning to Python 3.0 as
2361 the reload() built-in has been removed.
2362
Brett Cannon7e30b672008-08-04 21:52:25 +00002363- Changed code in the following modules/packages to remove warnings raised
Brett Cannonc1b76e42008-08-09 23:06:16 +00002364 while running under the ``-3`` flag: aifc, asynchat, asyncore, bdb, bsddb,

2372 raised an AttributeError.
2373
Benjamin Peterson01a24322008-07-28 23:35:27 +00002374- Issue #2523: Fix quadratic behaviour when read()ing a binary file without
Antoine Pitroude781a42008-08-09 12:43:23 +00002375 asking for a specific length. This problem only affected files opened
2376 using the new "io" module, not the built-in open() function.
Benjamin Peterson01a24322008-07-28 23:35:27 +00002377

2400
Antoine Pitrou5fdfa3e2008-07-25 19:42:26 +00002401- Issue #3394: zipfile.writestr sets external attributes when passed a
2402 file name rather than a ZipInfo instance, so files are extracted with
2403 mode 0600 rather than 000 under Unix.
2404
Gregory P. Smitha36f8fe2008-08-04 00:13:29 +00002405- Issue #1857: subprocess.Popen.poll gained an additional _deadstate keyword
2406 argument in python 2.5, this broke code that subclassed Popen to include its
2407 own poll method. Fixed my moving _deadstate to an _internal_poll method.

2416
Nick Coghlan6e8fef02008-08-18 13:14:22 +00002417- Issue #2235: the C API function PyObject_HashNotImplemented and its
2418 interaction with the tp_hash slot (added in 2.6b2) are now documented
2419
Nick Coghlan2a0c2b12008-08-04 12:47:17 +00002420- Issue #643841: The language reference now provides more detailed
2421 coverage of the lookup process for special methods. The disclaimers
2422 regarding lack of coverage of new-style classes have also been
2423 removed, since the coverage is now fairly reasonable.

2427================================
2428
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00002429*Release date: 17-Jul-2008*
2430
Raymond Hettingere3ae6552008-06-20 04:18:15 +00002431Core and Builtins
2432-----------------
2433
Georg Brandl3e483f62008-07-16 22:57:41 +00002434- Issue #3156: Fix inconsistent behavior of the bytearray type: all
2435 its methods now allow for items objects that can be converted to
2436 an integer using operator.index().
2437
Mark Dickinson64b7e502008-07-16 09:40:03 +00002438- Issue #3360: Fix incorrect parsing of '020000000000.0', which
2439 produced a ValueError instead of giving the correct float.
2440
Eric Smitha5fa5a22008-07-16 00:11:49 +00002441- Issue #3083: Add alternate (#) formatting for bin, oct, hex output
2442 for str.format(). This adds the prefix 0b, 0o, or 0x, respectively.
2443
Mark Dickinson7103aa42008-07-15 19:08:33 +00002444- Issue #3008: the float type has a new instance method 'float.hex'
2445 and a new class method 'float.fromhex' to convert floating-point
2446 numbers to and from hexadecimal strings, respectively.
2447
Nick Coghlan6d6bd442008-07-15 15:40:22 +00002448- Issue #2235: __hash__ is once again inherited by default. To allow
2449 collections.Hashable to remain meaningful in the presence of the
2450 default hash implementation (object.__hash__), it is now possible
2451 to explicit block inheritance of hash by setting __hash__=None at
2452 the Python level, or tp_hash=PyObject_HashNotImplemented at the C
2453 level.
2454
Nick Coghlanb028f502008-07-13 14:52:36 +00002455- Issue #3221: Issue a RuntimeWarning instead of raising SystemError if
2456 the parent module cannot be found while performing an absolute import.
2457 This means that an incorrectly defined __package__ attribute will
2458 now only prevent relative imports in that module rather than causing
2459 all imports from that module to fail.
2460
Nick Coghlan14ff9942008-07-08 14:21:42 +00002461- Issue #2517: Allow unicode messages in Exceptions again by correctly
2462 bypassing the instance dictionary when looking up __unicode__ on
2463 new-style classes.
2464
Amaury Forgeot d'Arcbdd941f2008-07-01 20:38:04 +00002465- Issue #3242: Fix a crash inside the print statement, if sys.stdout is
2466 set to a custom object whose write() method happens to install
2467 another file in sys.stdout.
2468
Amaury Forgeot d'Arc1f40c8a2008-06-30 22:42:40 +00002469- Issue #3088: Corrected a race condition in classes derived from
2470 threading.local: the first member set by a thread could be saved in
2471 another thread's dictionary.
2472
Mark Dickinson1ec2fcd2008-06-20 14:53:43 +00002473- Issue #3004: Minor change to slice.indices(): the start and stop
2474 arguments are now treated identically, making the behaviour easier
2475 to describe and understand. For example, slice(None, -10,
2476 1).indices(9) now returns (0, 0, 1) instead of (0, -1, 1), and
2477 slice(None, 10, -1).indices(10) returns (9, 9, -1) instead of (9,
2478 10, -1).
2479
Georg Brandl278fc502008-07-19 12:46:12 +00002480- Issue #3219: Calling a function with repeated keyword arguments,
2481 f(a=2, a=23), would not cause a syntax error. This was a regression
2482 from 2.4 caused by the switch to the new compiler.
Benjamin Peterson175e4d92008-07-01 19:34:52 +00002483
Georg Brandl278fc502008-07-19 12:46:12 +00002484- Issue #2862: Make int and float freelist management consistent with
2485 other freelists. Changes their CompactFreeList apis into
2486 ClearFreeList apis and calls them via gc.collect().
Gregory P. Smith2fe77062008-07-06 03:35:58 +00002487

2489-------
2490
Thomas Heller57adf222008-08-14 19:10:48 +00002491- Issue #3554: ctypes.string_at and ctypes.wstring_at did call Python
2492 api functions without holding the GIL, which could lead to a fatal
2493 error when they failed.
2494
Martin v. Löwisaabf4042008-08-02 07:20:25 +00002495- Issue #799428: Fix Tkinter.Misc._nametowidget to unwrap Tcl command objects.

Jesse Noller13e9d582008-07-16 14:32:36 +00002503- Issue #3125: Remove copy_reg in multiprocessing and replace it with
2504 ForkingPickler.register() to resolve conflict with ctypes.
2505
Vinay Sajip51e65192008-07-18 09:01:10 +00002506- Issue #3090: Fixed ARCHFLAGS parsing on OS/X
Jesse Noller13e9d582008-07-16 14:32:36 +00002507
Thomas Heller880f5292008-07-15 19:39:38 +00002508- Issue #3313: Fixed a crash when a failed dlopen() call does not set
2509 a valid dlerror() message.
2510
Thomas Heller2bad6572008-07-15 17:19:50 +00002511- Issue #3258: Fixed a crash when a ctypes POINTER type to an
2512 incomplete structure was created.
2513
Brett Cannon3d0b9f02008-07-13 01:15:07 +00002514- Issue #3339: dummy_thread.acquire() should not return None.

Raymond Hettingerb01713e2008-07-10 14:34:57 +00002516- Issue #3285: Fractions from_float() and from_decimal() accept Integral arguments.
2517
Andrew M. Kuchlingcc3f2b12008-07-10 14:43:31 +00002518- Issue #3301: Bisect module behaved badly when lo was negative.
Raymond Hettinger3cd1e422008-07-10 14:03:19 +00002519
Amaury Forgeot d'Arc0f7cddc2008-07-06 21:34:39 +00002520- Issue #839496: SimpleHTTPServer used to open text files in text mode. This is
2521 both unnecessary (HTTP allows text content to be sent in several forms) and
Andrew M. Kuchlingcc3f2b12008-07-10 14:43:31 +00002522 wrong because the actual transmitted size could differ from the
Amaury Forgeot d'Arc0f7cddc2008-07-06 21:34:39 +00002523 content-length. The problem had been corrected in the 2.4 branch, but never
2524 merged into trunk.
2525
Georg Brandle78fbcc2008-07-05 10:13:36 +00002526- Issue #2663: add filtering capability to shutil.copytree().

2532- Issue #1746: Correct handling of zipfile archive comments (previously
2533 archives with comments over 4k were flagged as invalid). Allow writing
Vinay Sajip51e65192008-07-18 09:01:10 +00002534 Zip files with archives by setting the 'comment' attribute of a ZipFile.
Martin v. Löwis8c436412008-07-03 12:51:14 +00002535
Vinay Sajip51e65192008-07-18 09:01:10 +00002536- Issue #449227: The rlcompleter module now adds "(" to callable objects
Andrew M. Kuchlingcc3f2b12008-07-10 14:43:31 +00002537 when completed.
Facundo Batista66c52772008-07-02 16:52:55 +00002538
Nick Coghlanc060b0e2008-07-02 13:09:19 +00002539- Issue #3190: Pydoc now hides the automatic module attribute __package__ (the
2540 handling is now the same as that of other special attributes like __name__).
2541
Brett Cannon8bb8fa52008-07-02 01:57:08 +00002542- Issue #2885 (partial): The urllib.urlopen() function has been deprecated for
2543 removal in Python 3.0 in favor of urllib2.urlopen().

Georg Brandl5cc774e2008-06-11 20:28:06 +00002932 PPC64 and x86_64 support in one binary).
Ronald Oussoren5640ce22008-06-05 12:58:24 +00002933
2934 This is controlled by the configure argument ``--with-universal-archs``:
2935
2936 - ``--with-universal-archs=all``: install 4-way universal
2937
2938 - ``--with-universal-archs=32-bit``: install 2-way universal, 32-bit (the default)
2939
2940 - ``--with-universal-archs=64-bit``: install 2-way universal, 64-bit
2941
2942 This option should be used in combination with ``--enable-universalsdk=``.
2943
2944 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 +00002994- Issue #1631171: Re-implement the 'warnings' module in C (the
2995 original Python code has been kept as backup). This will allow for
2996 using the 'warning's machinery in such places as the parser where
2997 use of pure Python code is not possible. Both the ``showarning()``
2998 and ``formatwarning()`` gain an optional 'line' argument which is
2999 not called by default for backwards-compatibility reasons. Setting
3000 ``warnings.showwarning()`` to an implementation that lacks support
3001 for the ``line`` argument will raise a DeprecationWarning.

Georg Brandl3ee81df2008-05-17 18:14:43 +00003064- Issue #2550: The approach used by client/server code for obtaining
3065 ports to listen on in network-oriented tests has been refined in an
3066 effort to facilitate running multiple instances of the entire
3067 regression test suite in parallel without issue.
3068 test_support.bind_port() has been fixed such that it will always
3069 return a unique port -- which wasn't always the case with the
3070 previous implementation, especially if socket options had been set
3071 that affected address reuse (i.e. SO_REUSEADDR, SO_REUSEPORT). The
3072 new implementation of bind_port() will actually raise an exception
3073 if it is passed an AF_INET/SOCK_STREAM socket with either the
3074 SO_REUSEADDR or SO_REUSEPORT socket option set. Furthermore, if
3075 available, bind_port() will set the SO_EXCLUSIVEADDRUSE option on
3076 the socket it's been passed. This currently only applies to
3077 Windows. This option prevents any other sockets from binding to the
3078 host/port we've bound to, thus removing the possibility of the
3079 'non-deterministic' behaviour, as Microsoft puts it, that occurs
3080 when a second SOCK_STREAM socket binds and accepts to a host/port
3081 that's already been bound by another socket. The optional preferred
3082 port parameter to bind_port() has been removed. Under no
3083 circumstances should tests be hard coding ports!
3084
3085 test_support.find_unused_port() has also been introduced, which will
3086 pass a temporary socket object to bind_port() in order to obtain an
3087 unused port. The temporary socket object is then closed and
3088 deleted, and the port is returned. This method should only be used
3089 for obtaining an unused port in order to pass to an external program
3090 (i.e. the -accept [port] argument to openssl's s_server mode) or as
3091 a parameter to a server-oriented class that doesn't give you direct
3092 access to the underlying socket used.
3093
3094 Finally, test_support.HOST has been introduced, which should be used
3095 for the host argument of any relevant socket calls (i.e. bind and
3096 connect).
Trent Nelsone41b0062008-04-08 23:47:30 +00003097
3098 The following tests were updated to following the new conventions:
Georg Brandl3ee81df2008-05-17 18:14:43 +00003099 test_socket, test_smtplib, test_asyncore, test_ssl, test_httplib,

3372
Fred Drakea8ee94b2008-03-01 02:45:07 +00003373- Issue #2051: pyc and pyo files are no longer created with permission
Barry Warsaw52973612008-03-01 02:23:38 +00003374 644. The mode is now inherited from the py file.
Christian Heimes40346852008-02-23 17:52:07 +00003375
Georg Brandlad61bc82008-02-23 15:11:18 +00003376- Issue #2067: file.__exit__() now calls subclasses' close() method.
3377
3378- Patch #1759: Backport of PEP 3129 class decorators.
Christian Heimes5224d282008-02-23 15:01:05 +00003379
Vinay Sajipb7edfc42008-04-02 21:10:23 +00003380- Issue #1881: An internal parser limit has been increased. Also see
Facundo Batistafc2d0102008-02-23 12:01:13 +00003381 issue 215555 for a discussion.
3382
Eric Smitha73fbe72008-02-23 03:09:44 +00003383- Added the future_builtins module, which contains hex() and oct().
3384 These are the PEP 3127 version of these functions, designed to be
3385 compatible with the hex() and oct() builtins from Python 3.0. They
3386 differ slightly in their output formats from the existing, unchanged
3387 Python 2.6 builtins. The expected usage of the future_builtins
3388 module is:
3389 from future_builtins import hex, oct
3390
Eric Smith7ef40bf2008-02-20 23:34:22 +00003391- Issue #1600: Modifed PyOS_ascii_formatd to use at most 2 digit
3392 exponents for exponents with absolute value < 100. Follows C99
3393 standard. This is a change on Windows, which would use 3 digits.
3394 Also, added 'n' to the formats that PyOS_ascii_formatd understands,
3395 so that any alterations it does to the resulting string will be
3396 available in stringlib/formatter.h (for float.__format__).
3397
Eric Smith5a3c1352008-02-19 13:21:56 +00003398- Implemented PEP 3101, Advanced String Formatting. This adds a new
3399 builtin format(); a format() method for str and unicode; a
3400 __format__() method to object, str, unicode, int, long, float, and
3401 datetime; the class string.Formatter; and the C API
3402 PyObject_Format().
3403
Georg Brandl3ee81df2008-05-17 18:14:43 +00003404- Fixed several potential crashes, all caused by specially crafted
3405 __del__ methods exploiting objects in temporarily inconsistent
3406 state.
Amaury Forgeot d'Arc632fad32008-02-16 20:55:24 +00003407
Vinay Sajipb7edfc42008-04-02 21:10:23 +00003408- Issue #2115: Important speedup in setting __slot__ attributes. Also
Georg Brandl3ee81df2008-05-17 18:14:43 +00003409 prevent a possible crash: an Abstract Base Class would try to access
3410 a slot on a registered virtual subclass.
Amaury Forgeot d'Arc60d6c7f2008-02-15 21:22:45 +00003411
Georg Brandl3ee81df2008-05-17 18:14:43 +00003412- Fixed repr() and str() of complex numbers with infinity or nan as
3413 real or imaginary part.
Christian Heimes2f0da532008-02-15 06:57:08 +00003414
Georg Brandl3ee81df2008-05-17 18:14:43 +00003415- Clear all free lists during a gc.collect() of the highest generation
3416 in order to allow pymalloc to free more arenas. Python may give back
3417 memory to the OS earlier.
Christian Heimes3b718a72008-02-14 12:47:33 +00003418
Georg Brandl3ee81df2008-05-17 18:14:43 +00003419- Issue #2045: Fix an infinite recursion triggered when printing a
3420 subclass of collections.defaultdict, if its default_factory is set
3421 to a bound method.
Amaury Forgeot d'Arcb01aa432008-02-08 00:56:02 +00003422
Christian Heimesf75dbef2008-02-08 00:11:31 +00003423- Fixed a minor memory leak in dictobject.c. The content of the free
3424 list was not freed on interpreter shutdown.
3425
Georg Brandl3ee81df2008-05-17 18:14:43 +00003426- Limit free list of method and builtin function objects to 256
3427 entries each.
Christian Heimes6075a822008-02-06 12:44:34 +00003428
Georg Brandl3ee81df2008-05-17 18:14:43 +00003429- Patch #1953: Added ``sys._compact_freelists()`` and the C API
3430 functions ``PyInt_CompactFreeList`` and ``PyFloat_CompactFreeList``
Christian Heimes422051a2008-02-04 18:00:12 +00003431 to compact the internal free lists of pre-allocted ints and floats.
3432
Georg Brandl3ee81df2008-05-17 18:14:43 +00003433- Issue #1983: Fixed return type of fork(), fork1() and forkpty()
3434 calls. Python expected the return type int but the fork familie
3435 returns pi_t.
Christian Heimes951cc0f2008-01-31 23:08:23 +00003436
Georg Brandl3ee81df2008-05-17 18:14:43 +00003437- Issue #1678380: Fix a bug that identifies 0j and -0j when they
3438 appear in the same code unit.
Mark Dickinson105be772008-01-31 22:17:37 +00003439
Georg Brandl3ee81df2008-05-17 18:14:43 +00003440- Issue #2025: Add tuple.count() and tuple.index() methods to comply
3441 with the collections.Sequence API.
Raymond Hettinger5b07ebc2008-02-07 00:54:20 +00003442
Georg Brandl3ee81df2008-05-17 18:14:43 +00003443- Patch #1970 by Antoine Pitrou: Speedup unicode whitespace and
3444 linebreak detection
Christian Heimes4d4f2702008-01-30 11:32:37 +00003445
Georg Brandl3ee81df2008-05-17 18:14:43 +00003446- Added ``PyType_ClearCache()`` and ``sys._clear_type_cache`` to clear
3447 the internal lookup cache for ref leak tests.
Christian Heimes908caac2008-01-27 23:34:59 +00003448
Georg Brandl3ee81df2008-05-17 18:14:43 +00003449- Patch #1473257: generator objects gain a gi_code attribute. This is
3450 the same object as the func_code attribute of the function that
3451 produced the generator.
Georg Brandl0cdf9a32008-01-26 14:14:20 +00003452
Georg Brandl3ee81df2008-05-17 18:14:43 +00003453- Issue #1920: "while 0" statements were completely removed by the
3454 compiler, even in the presence of an "else" clause, which is
3455 supposed to be run when the condition is false. Now the compiler
3456 correctly emits bytecode for the "else" suite.
Amaury Forgeot d'Arc31eaafe2008-01-24 22:59:25 +00003457
Guido van Rossumeead05f2008-01-24 18:21:02 +00003458- A few crashers fixed: weakref_in_del.py (issue #1377858);
3459 loosing_dict_ref.py (issue #1303614, test67.py);
3460 borrowed_ref_[34].py (not in tracker).
3461
Vinay Sajipd7cf32e2008-01-24 12:43:33 +00003462- Issue #1069410: The "can't load dll" message box on Windows is
Christian Heimesb2302ba2008-01-23 17:15:06 +00003463 suppressed while an extension is loaded by calling SetErrorMode in
3464 dynload_win.c. The error is still reported properly.
3465
Georg Brandl3ee81df2008-05-17 18:14:43 +00003466- Issue #1915: Python compiles with --enable-unicode=no again. However
Christian Heimes082c9b02008-01-23 14:20:50 +00003467 several extension methods and modules do not work without unicode
3468 support.
3469
Georg Brandl26543b12008-01-21 18:36:51 +00003470- Issue #1882: when compiling code from a string, encoding cookies in the
3471 second line of code were not always recognized correctly.
3472
Georg Brandl14404b62008-01-19 19:27:05 +00003473- Issue #1679: "0x" was taken as a valid integer literal.
3474
Georg Brandl6caad7d2008-01-26 14:19:22 +00003475- Issue #1865: ``bytes`` as an alias for ``str`` and b"" as an alias "" were
Christian Heimes288e89a2008-01-18 18:24:07 +00003476 added.
3477
Christian Heimesc94e2b52008-01-14 04:13:37 +00003478- sys.float_info / PyFloat_GetInfo: The floating point information
3479 object was converted from a dict to a specialized structseq object.
3480
Georg Brandl3ee81df2008-05-17 18:14:43 +00003481- Patch #1816: Added sys.flags structseq. It exposes the status of
3482 most command line arguments and PYTHON* environment variables.
Christian Heimesf31b69f2008-01-14 03:42:48 +00003483
Georg Brandl3ee81df2008-05-17 18:14:43 +00003484- Objects/structseq.c: Implemented new structseq representation. The
3485 patch makes structseqs (e.g. the return value of os.stat) more
3486 readable.
Christian Heimes9c201962008-01-14 03:33:52 +00003487
Georg Brandl3ee81df2008-05-17 18:14:43 +00003488- Patch #1700288: added a type attribute cache that caches method
3489 accesses, resulting in speedups in heavily object-oriented code.
Amaury Forgeot d'Arce4c270c2008-01-14 00:29:41 +00003490
Neal Norwitz3fc15b82008-01-10 05:42:58 +00003491- Bug #1776: __import__() no longer accepts filenames on any platform.
3492 The first parameter to __import__() must be a valid module name.
Christian Heimes3403f152008-01-09 19:56:33 +00003493
Georg Brandlaed6c662008-01-07 17:25:53 +00003494- Patch #1668: renamed THREADDEBUG envvar to PYTHONTHREADDEBUG.
3495
Georg Brandl3ee81df2008-05-17 18:14:43 +00003496- Patch #602345: Add -B command line option, PYTHONDONTWRITEBYTECODE
3497 envvar and sys.dont_write_bytecode attribute. All these can be set
3498 to forbid Python to attempt to write compiled bytecode files.
Georg Brandl2da0fce2008-01-07 17:09:35 +00003499
Georg Brandl3ee81df2008-05-17 18:14:43 +00003500- Improve some exception messages when Windows fails to load an
3501 extension module. Now we get for example '%1 is not a valid Win32
3502 application' instead of 'error code 193'.
Amaury Forgeot d'Arce0b76952008-01-04 02:04:15 +00003503
Georg Brandl3ee81df2008-05-17 18:14:43 +00003504- Bug #1481296: Fixed long(float('nan')) != 0L.

Georg Brandl3ee81df2008-05-17 18:14:43 +00003506- Issue #1640: Added math.isinf(x), math.isnan(x) and math.copysign(x,
3507 y) functions.
Christian Heimese2ca4242008-01-03 20:23:15 +00003508
Christian Heimes0a8143f2007-12-18 23:22:54 +00003509- Issue #1635: Platform independent creation and representation of NaN
Georg Brandl3ee81df2008-05-17 18:14:43 +00003510 and INF. float("nan"), float("inf") and float("-inf") now work on
3511 every platform with IEEE 754 semantics.
Christian Heimes0a8143f2007-12-18 23:22:54 +00003512
Georg Brandl3ee81df2008-05-17 18:14:43 +00003513- Compiler now generates simpler and faster code for dictionary
3514 literals. The oparg for BUILD_MAP now indicates an estimated
3515 dictionary size. There is a new opcode, STORE_MAP, for adding
3516 entries to the dictionary.
Raymond Hettingerfd7ed402007-12-18 21:24:09 +00003517
Georg Brandl3ee81df2008-05-17 18:14:43 +00003518- Issue #1638: %zd configure test fails on Linux.

3534 running, and if the deallocation of its frames somehow calls the
3535 PyGILState_Ensure() / PyGILState_Release() functions.
Amaury Forgeot d'Arcbe49a902007-11-30 20:37:22 +00003536

3546 file can now be directly executed by passing their name to the
3547 interpreter. The directory/zipfile is automatically inserted as the
3548 first entry in sys.path.
Nick Coghlan327a39b2007-11-18 11:56:28 +00003549
Georg Brandl3ee81df2008-05-17 18:14:43 +00003550- Issue #1265: Fix a problem with sys.settrace, if the tracing
3551 function uses a generator expression when at the same time the
3552 executed code is closing a paused generator.
Amaury Forgeot d'Arc0d75f092007-11-13 21:54:28 +00003553
Raymond Hettinger1760c8a2007-11-08 02:52:43 +00003554- sets and frozensets now have an isdisjoint() method.
3555
Raymond Hettinger3f8caa32007-10-24 01:28:33 +00003556- optimize the performance of builtin.sum().
3557
Neal Norwitz44f326e2007-10-05 05:29:17 +00003558- Fix warnings found by the new version of the Coverity checker.
3559
Georg Brandl3ee81df2008-05-17 18:14:43 +00003560- The enumerate() builtin function is no longer bounded to sequences
3561 smaller than LONG_MAX. Formerly, it raised an OverflowError. Now,
3562 automatically shifts from ints to longs.
Raymond Hettinger8f669372007-10-03 21:18:11 +00003563
Georg Brandl3ee81df2008-05-17 18:14:43 +00003564- Issue #1686386: Tuple's tp_repr did not take into account the
3565 possibility of having a self-referential tuple, which is possible
3566 from C code. Nor did object's tp_str consider that a type's tp_str
3567 could do something that could lead to an inifinite recursion.
3568 Py_ReprEnter() and Py_EnterRecursiveCall(), respectively, fixed the
3569 issues.
Brett Cannon0b14f242007-09-30 19:45:10 +00003570
Georg Brandl3ee81df2008-05-17 18:14:43 +00003571- Issue #1164: It was possible to trigger deadlock when using the
3572 'print' statement to write to a file since the GIL was not released
3573 as needed. Now PyObject_Print() does the right thing along with
3574 various tp_print implementations of the built-in types and those in
3575 the collections module.
Brett Cannon01531592007-09-17 03:28:34 +00003576
Georg Brandl3ee81df2008-05-17 18:14:43 +00003577- Issue #1147: Exceptions were directly allowing string exceptions in
3578 their throw() method even though string exceptions no longer
3579 allowed.
Brett Cannon4c20bc42007-09-11 21:02:28 +00003580

Brett Cannon1e534b52007-09-07 04:18:30 +00003584- Issue #1202533: Fix infinite recursion calls triggered by calls to
Georg Brandl3ee81df2008-05-17 18:14:43 +00003585 PyObject_Call() never calling back out to Python code to trigger
3586 recursion depth updates/checks. Required the creation of a static
3587 RuntimeError instance in case normalizing an exception put the
3588 recursion check value past its limit. Fixes crashers
3589 infinite_rec_(1|2|4|5).py.
Brett Cannon1e534b52007-09-07 04:18:30 +00003590

Georg Brandl3ee81df2008-05-17 18:14:43 +00003605 __*__ attributes. (Some already existed, e.g., __doc__ and
3606 __name__.)
Neal Norwitz0ac60192007-05-27 04:08:54 +00003607
Neal Norwitz8b2bfbc2007-05-23 06:35:32 +00003608- Add -3 option to the interpreter to warn about features that are
3609 deprecated and will be changed/removed in Python 3.0.
3610
Georg Brandl2134e752007-05-21 20:34:16 +00003611- Patch #1686487: you can now pass any mapping after '**' in function
3612 calls.
3613
Collin Winter62903052007-05-18 23:11:24 +00003614- except clauses may now be spelled either "except E, target:" or
Georg Brandl3ee81df2008-05-17 18:14:43 +00003615 "except E as target:". This is to provide forwards compatibility
3616 with Python 3.0.
Collin Winter62903052007-05-18 23:11:24 +00003617
Brett Cannon229cee22007-05-05 01:34:02 +00003618- Deprecate BaseException.message as per PEP 352.
3619
Georg Brandl3ee81df2008-05-17 18:14:43 +00003620- Issue #1303614: don't expose object's __dict__ when the dict is
Armin Rigo9790a272007-05-02 19:23:31 +00003621 inherited from a builtin base.
3622
Vinay Sajip8549ce32007-05-06 17:53:37 +00003623- When __slots__ are set to a unicode string, make it work the same as
Neal Norwitzcbd9ee62007-04-14 05:25:50 +00003624 setting a plain string, ie don't expand to single letter identifiers.
3625
Raymond Hettinger13936692007-04-11 18:40:58 +00003626- Request #1191699: Slices can now be pickled.

3636
Guido van Rossum143b5642007-03-23 04:58:42 +00003637- Bug #1683368: The object.__init__() and object.__new__() methods are
3638 now stricter in rejecting excess arguments. The only time when
3639 either allows excess arguments is when it is not overridden and the
3640 other one is. For backwards compatibility, when both are
3641 overridden, it is a deprecation warning (for now; maybe a Py3k
Guido van Rossum234b1ff2007-03-23 19:39:01 +00003642 warning later). Also, type.__init__() insists on the same signature
3643 as supported by type.__new__().

Georg Brandl3ee81df2008-05-17 18:14:43 +00003645- Patch #1675423: PyComplex_AsCComplex() now tries to convert an
3646 object to complex using its __complex__() method before falling back
3647 to the __float__() method. Therefore, the functions in the cmath
3648 module now can operate on objects that define a __complex__()
3649 method.

3666
Georg Brandl7b9c5552007-03-12 14:30:05 +00003667- Bug #1678647: write a newline after printing an exception in any
3668 case, even when converting the value to a string failed.
3669
Georg Brandl871f1bc2007-03-12 13:17:36 +00003670- The dir() function has been extended to call the __dir__() method on
Georg Brandl3ee81df2008-05-17 18:14:43 +00003671 its argument, if it exists. If not, it will work like before. This
3672 allows customizing the output of dir() in the presence of a
3673 __getattr__().

3676 self-recursive reload() calls (as reported by bug #742342).

3682 parthensized forms. This means complex(repr(x)) now works instead of
3683 raising a ValueError.
Collin Wintere38051d2007-03-09 20:33:07 +00003684
Georg Brandlaa2321b2007-03-07 00:40:28 +00003685- Patch #703779: unset __file__ in __main__ after running a file. This
Georg Brandl3ee81df2008-05-17 18:14:43 +00003686 makes the filenames the warning module prints much more sensible
3687 when a PYTHONSTARTUP file is used.
Georg Brandlaa2321b2007-03-07 00:40:28 +00003688

Georg Brandl0fca97a2007-03-05 22:28:08 +00003700- Patch #1674228: when assigning a slice (old-style), check for the
3701 sq_ass_slice instead of the sq_slice slot.
3702
Georg Brandl3ee81df2008-05-17 18:14:43 +00003703- When printing an unraisable error, don't print exceptions. before

Georg Brandl3ee81df2008-05-17 18:14:43 +00003806 generator expressions (x for x, in ... ) works again. Fixing this

Georg Brandl3ee81df2008-05-17 18:14:43 +00004615- Issue #829951: In the smtplib module, SMTP.starttls() now complies
4616 with RFC 3207 and forgets any knowledge obtained from the server not
4617 obtained from the TLS negotiation itself. Patch contributed by Bill
4618 Fenner.
Gregory P. Smith2b3ba582008-01-17 08:03:17 +00004619
Georg Brandl3ee81df2008-05-17 18:14:43 +00004620- Issue #1339: The smtplib.SMTP class has been refactored a bit such
Gregory P. Smithbde4ae42008-01-17 08:35:49 +00004621 that the SMTP.starttls() caller no longer needs to call ehlo()
4622 beforehand. SMTP.starttls() now raises an exception of the server
Georg Brandl3ee81df2008-05-17 18:14:43 +00004623 does not claim to support starttls. Adds the
4624 SMTP.ehlo_or_helo_if_needed() method. Patch contributed by Bill

4705 complex, tuple, list, dict, set, and frozenset. Formerly, it would
4706 silently miscode subclasses of those types. Now, it raises a
4707 ValueError instead.
Raymond Hettinger12e94202007-11-07 01:13:09 +00004708

Georg Brandl3ee81df2008-05-17 18:14:43 +00004723 time so that opening a database previously created with the DB_DUP
4724 or DB_DUPSORT flag set will keep the proper behavior on subsequent
4725 opens. Specifically: dictionary assignment to a DB object will
4726 replace all values for a given key when the database allows
4727 duplicate values. DB users should use DB.put(k, v) when they want
4728 to store duplicates; not DB[k] = v.
Gregory P. Smithec10a4a2007-11-05 02:32:26 +00004729

4735 characters with ASCII value less than 32. Also, it correctly quotes
4736 dots only if they occur on a single line, as opposed to the previous
4737 behavior of quoting dots if they are the second character of any
4738 line.
Georg Brandl4aef7272007-03-13 22:49:43 +00004739

Georg Brandl3ee81df2008-05-17 18:14:43 +00005144- Removed the macfs module. It had been deprecated since Python 2.5.
5145 This lead to the deprecation of macostools.touched() as it relied
5146 solely on macfs and was a no-op under OS X.
