Benjamin Peterson4f51baf2009-12-05 18:40:02 +000056What's New in Python 2.7 alpha 2?

61Core and Builtins
62-----------------
63
Benjamin Petersonecdae192010-01-04 00:43:01 +000064- The __complex__ method is now looked up on the class of instances to make it
65 consistent with other special methods.
66
Antoine Pitrou5b7139a2010-01-02 21:12:58 +000067- Issue #7462: Implement the stringlib fast search algorithm for the `rfind`,
68 `rindex`, `rsplit` and `rpartition` methods. Patch by Florent Xicluna.
69
Mark Dickinson1b34d252010-01-01 17:27:30 +000070- Issue #5080: A number of functions and methods previously produced a
71 DeprecationWarning when passed a float argument where an integer was
72 expected. These functions and methods now raise TypeError instead.
73 The majority of the effects of this change are in the extension
74 modules, but some core functions and methods are affected: notably
75 the 'chr', 'range' and 'xrange' builtins, and many unicode/str
76 methods.
77
Benjamin Peterson0f02d392009-12-30 19:34:10 +000078- Issue #7604: Deleting an unset slotted attribute did not raise an
79 AttributeError.

Mark Dickinson99d652e2009-12-30 12:12:23 +000081- Issue #7534: Fix handling of IEEE specials (infinities, nans,
82 negative zero) in ** operator. The behaviour now conforms to that
83 described in C99 Annex F.
84
Amaury Forgeot d'Arcc8a2ce72009-12-29 23:06:17 +000085- Issue #7579: the msvcrt module now has docstrings for all its functions.
86
Amaury Forgeot d'Arc8645a5c2009-12-29 22:03:38 +000087- Issue #7413: Passing '\0' as the separator to datetime.datetime.isoformat()
88 used to drop the time part of the result.
89
Mark Dickinson46572832009-12-27 14:55:57 +000090- Issue #1811: improve accuracy and cross-platform consistency for
91 true division of integers: the result of a/b is now correctly
92 rounded for ints a and b (at least on IEEE 754 platforms), and in
93 particular does not depend on the internal representation of a long.
94
Ezio Melottif84caf42009-12-24 22:25:17 +000095- Issue #6108: unicode(exception) and str(exception) should return the same
96 message when only __str__ (and not __unicode__) is overridden in the subclass.
97
Ronald Oussoren92919a62009-12-24 13:30:58 +000098- Issue #6834: replace the implementation for the 'python' and 'pythonw'
99 executables on OSX.
100
101 These executables now work properly with the arch(1) command:
102 ``arch -ppc python`` will start a universal binary version of python
103 in PPC mode (unlike previous releases).
104
R. David Murray0a0a1a82009-12-14 16:28:26 +0000105- Issue #1680159: unicode coercion during an 'in' operation no longer masks
106 the underlying error when the coercion fails for the left hand operand.

119 by Arfrever.
120
Antoine Pitrou80157252010-01-08 19:20:17 +0000121- Issue #7092: Remove py3k warning when importing cPickle. 2to3 handles
122 renaming of `cPickle` to `pickle`. The warning was annoying since there's
123 no alternative to cPickle if you care about performance. Patch by Florent
124 Xicluna.
125
Antoine Pitrou0d423b82010-01-07 17:46:49 +0000126- Issue #7455: Fix possible crash in cPickle on invalid input. Patch by

133 and make it implement the `io.BufferedIOBase` ABC to allow for further
134 speedups by wrapping it in an `io.BufferedReader`. Patch by Nir Aides.
135
136- Issue #3972: httplib.HTTPConnection now accepts an optional source_address

Senthil Kumaran7713acf2009-12-20 06:05:13 +0000155 Patch by Tatsuhiro Tsujikawa.
156
Benjamin Petersonddd392c2009-12-13 19:19:07 +0000157- Issue #7349: Make methods of file objects in the io module accept None as an
158 argument where file-like objects (ie StringIO and BytesIO) accept them to mean
159 the same as passing no argument.
160
Benjamin Petersonc4771d22009-12-13 17:31:31 +0000161- Issue #7348: StringIO.StringIO.readline(-1) now acts as if it got no argument
162 like other file objects.
163

170 missing proper end-of-line termination.
171
Tarek Ziadé2421d562009-12-20 23:23:34 +0000172- Issue #7457: added a read_pkg_file method to

229Core and Builtins
230-----------------
231
Amaury Forgeot d'Arcd7288712009-12-01 21:51:04 +0000232- Issue #7419: setlocale() could crash the interpreter on Windows when called
233 with invalid values.
234
Eric Smithc4ab8332009-11-29 17:40:57 +0000235- Issue #3382: 'F' formatting for float and complex now convert the
236 result to upper case. This only affects 'inf' and 'nan', since 'f'
237 no longer converts to 'g' for large values.
Amaury Forgeot d'Arcd7288712009-12-01 21:51:04 +0000238
Mark Dickinson9dd5e162009-11-23 20:54:09 +0000239- Remove switch from "%f" formatting to "%g" formatting for floats
240 larger than 1e50 in absolute value.
241
Mark Dickinson18cfada2009-11-23 18:46:41 +0000242- Remove restrictions on precision when formatting floats. E.g.,
243 "%.120g" % 1e-100 used to raise OverflowError, but now gives the
244 requested 120 significant digits instead.
245
Benjamin Peterson89b1a5c2009-11-19 22:58:01 +0000246- Add Py3k warnings for parameter names in parenthesis.
247
Benjamin Peterson48f0a8d2009-11-19 23:19:29 +0000248- Issue #7362: Give a proper error message for def f((x)=3): pass.
Benjamin Peterson89b1a5c2009-11-19 22:58:01 +0000249
Ronald Oussoren315cd0c2009-11-19 16:25:21 +0000250- Issue #7085: Fix crash when importing some extensions in a thread
251 on MacOSX 10.6.
252
Mark Dickinsonb678de82009-11-19 18:41:49 +0000253- Issue #7117: repr(x) for a float x returns a result based on the
254 shortest decimal string that's guaranteed to round back to x under
255 correct rounding (with round-half-to-even rounding mode).
256 Previously it gave a string based on rounding x to 17 decimal digits.
257 repr(x) for a complex number behaves similarly. On platforms where
258 the correctly-rounded strtod and dtoa code is not supported (see below),
259 repr is unchanged.
260
261- Issue #7117: On almost all platforms: float-to-string and
262 string-to-float conversions within Python are now correctly rounded.
263 Places these conversions occur include: str for floats and complex
264 numbers; the float and complex constructors; old-style and new-style
265 numeric formatting; serialization and deserialization of floats and
266 complex numbers using marshal, pickle and json; parsing of float and
267 imaginary literals in Python code; Decimal-to-float conversion.
268
269 The conversions use a Python-adapted version of David Gay's
270 well-known dtoa.c, providing correctly-rounded strtod and dtoa C
271 functions. This code is supported on Windows, and on Unix-like
272 platforms using gcc, icc or suncc as the C compiler. There may be a
273 small number of platforms on which correct operation of this code
274 cannot be guaranteed, so the code is not used: notably, this applies
275 to platforms where the C double format is not IEEE 754 binary64, and
276 to platforms on x86 hardware where the x87 FPU is set to 64-bit
277 precision and Python's configure script is unable to determine how
278 to change the FPU precision. On these platforms conversions use the
279 platform strtod and dtoa, as before.
280
Mark Dickinsonbd15a062009-11-18 19:33:35 +0000281- Issue #7117: Backport round implementation from Python 3.x. round
Mark Dickinsonb678de82009-11-19 18:41:49 +0000282 now uses the correctly-rounded string <-> float conversions
283 described above (when available), and so produces correctly rounded
284 results that will display nicely under the float repr. There are
285 two related small changes: (1) round now accepts any class with an
286 __index__ method for its second argument (but no longer accepts
Mark Dickinsonbd15a062009-11-18 19:33:35 +0000287 floats for the second argument), and (2) an excessively large second
288 integer argument (e.g., round(1.234, 10**100)) no longer raises an
289 exception.
290
Philip Jenveyfab8be22009-11-17 02:42:26 +0000291- Issue #1757126: Fix the cyrillic-asian alias for the ptcp154 encoding.
292
Benjamin Petersone36199b2009-11-12 23:39:44 +0000293- Fix several issues with compile(). The input can now contain Windows and Mac
294 newlines and is no longer required to end in a newline.
295
Mark Dickinsonc04c7c52009-10-26 22:28:14 +0000296- Remove length limitation when constructing a complex number from a
297 unicode string.
298
Raymond Hettingerfa7dadd2009-11-01 20:45:16 +0000299- Issue #7244: itertools.izip_longest() no longer ignores exceptions
300 raised during the formation of an output tuple.
301
Mark Dickinson8d87dc02009-10-25 20:39:06 +0000302- Issue #1087418: Boost performance of bitwise operations for longs.
303
Antoine Pitrouefb60c02009-10-20 21:29:37 +0000304- Issue #1722344: threading._shutdown() is now called in Py_Finalize(), which
305 fixes the problem of some exceptions being thrown at shutdown when the
306 interpreter is killed. Patch by Adam Olsen.
307
Eric Smithc12781a2009-10-19 14:38:14 +0000308- Issue #7168: Document PyFloat_AsString and PyFloat_AsReprString, and

Mark Dickinsonb1d45852009-05-11 15:33:08 +0000431- Issue #5981: Fix three minor inf/nan issues in float.fromhex:
432 (1) inf and nan strings with trailing whitespace were incorrectly

434 was locale aware; and (3) the interpretation of fromhex('-nan')
435 didn't match that of float('-nan').
436
Eric Smitha985a3a2009-05-05 18:26:08 +0000437- Issue #5920: For float.__format__, change the behavior with the
438 empty presentation type (that is, not one of 'e', 'f', 'g', or 'n')
439 to be like 'g' but with at least one decimal point and with a
440 default precision of 12. Previously, the behavior the same but with
441 a default precision of 6. This more closely matches str(), and
442 reduces surprises when adding alignment flags to the empty
443 presentation type. This also affects the new complex.__format__ in
444 the same way.
445
R. David Murray7ba8e1c2009-05-04 22:16:24 +0000446- Issue #5890: in subclasses of 'property' the __doc__ attribute was

510 reduce the size of collections and therefore the garbage collection overhead
511 on long-running programs, depending on their particular use of datatypes.
512
Mark Dickinson0b666bf2009-03-23 18:25:13 +0000513- Issue #5512: Rewrite PyLong long division algorithm (x_divrem) to

546 on a 64-bit system.
547
Antoine Pitrou76a4b892009-02-13 13:52:33 +0000548- Issue #5186: Reduce hash collisions for objects with no __hash__ method by

555
Georg Brandl29c6a282009-04-05 20:23:13 +0000556- Issue #1242657: the __len__() and __length_hint__() calls in several tools
Raymond Hettingerb5163702009-02-02 21:50:13 +0000557 were suppressing all exceptions. These include list(), filter(), map(),

629 exceptions.
630
Mark Dickinson826f3fe2008-12-05 21:55:28 +0000631- Issue #4445: Replace "sizeof(PyStringObject)" with
632 "offsetof(PyStringObject, ob_sval) + 1" when allocating memory for
633 str instances. On a typical machine this saves 3 bytes of memory
634 (on average) per string allocation.
635
Amaury Forgeot d'Arcdc619012008-11-22 20:01:18 +0000636- Issue #3996: On Windows, the PyOS_CheckStack function would cause the
637 interpreter to abort ("Fatal Python error: Could not reset the stack!")
638 instead of throwing a MemoryError.
639
Raymond Hettinger7989a4d2008-12-03 15:42:10 +0000640- Issue #3689: The list reversed iterator now supports __length_hint__

642
Benjamin Petersonc078f922008-11-21 22:27:24 +0000643- Issue #4367: Python would segfault during compiling when the unicodedata

645
Vinay Sajip213faca2008-12-03 23:22:58 +0000646- Issue #4233: Changed semantic of ``_fileio.FileIO``'s ``close()``
Amaury Forgeot d'Arc32265652008-11-20 23:34:31 +0000647 method on file objects with closefd=False. The file descriptor is still
648 kept open but the file object behaves like a closed file. The ``FileIO``
649 object also got a new readonly attribute ``closefd``.
650
Benjamin Peterson46cc6d12008-11-19 21:49:09 +0000651- Issue #4348: Some bytearray methods returned that didn't cause any change to
652 the bytearray, returned the same bytearray instead of a copy.
653

665
Benjamin Petersonbdca9422008-10-26 20:21:13 +0000666- Issue #4209: Enabling unicode_literals and the print_function in the same
667 __future__ import didn't work.
668
Benjamin Peterson399b1fe2008-10-25 02:53:28 +0000669- Using ``nonlocal`` as a variable name will now raise a Py3k SyntaxWarning
Georg Brandl7fb00ad2008-10-25 07:00:52 +0000670 because it is a reserved word in 3.x.
Benjamin Peterson399b1fe2008-10-25 02:53:28 +0000671
Hirokazu Yamamoto10a018c2008-10-09 10:00:30 +0000672- On windows, os.chdir given unicode was not working if GetCurrentDirectoryW
673 returned a path longer than MAX_PATH. (But It's doubtful this code path is
674 really executed because I cannot move to such directory on win2k)
675
Amaury Forgeot d'Arcd78b9dc2008-10-07 20:32:10 +0000676- Issue #4069: When set.remove(element) is used with a set element, the element
677 is temporarily replaced with an equivalent frozenset. But the eventual
678 KeyError would always report the empty frozenset([]) as the missing key. Now
679 it correctly refers to the initial element.

697 returned them on 64bit platforms.
698
Walter Dörwalded960ac2009-05-03 22:36:33 +0000699- Issue #5108: Handle %s like %S and %R in PyUnicode_FromFormatV(): Call
700 PyUnicode_DecodeUTF8() once, remember the result and output it in a second
701 step. This avoids problems with counting UTF-8 bytes that ignores the effect
702 of using the replace error handler in PyUnicode_DecodeUTF8().
703
Walter Dörwald726ba8e2009-05-06 14:32:35 +0000704- Issue #3739: The unicode-internal encoder now reports the number of characters
705 consumed like any other encoder (instead of the number of bytes).
706
Benjamin Peterson91c12eb2009-12-03 02:52:39 +0000707- Issue #2422: When compiled with the ``--with-valgrind`` option, the
708 pymalloc allocator will be automatically disabled when running under
709 Valgrind. This gives improved memory leak detection when running
710 under Valgrind, while taking advantage of pymalloc at other times.

2091
Amaury Forgeot d'Arc05e34492008-09-10 22:04:45 +00002092- Issue #3743: In a few places, PY_FORMAT_SIZE_T was incorrectly used with
2093 PyString_FromFormat or PyErr_Format to display size_t values. The macro
2094 PY_FORMAT_SIZE_T is designed to select the correct format for the OS
2095 ``printf`` function, whereas PyString_FromFormat has an independent
2096 implementation and uses "%zd" on all platforms for size_t values.
2097 This makes a difference on win64, where ``printf`` needs "%Id" to display
2098 64bit values.

2104 object; previously an int would be returned for small values. the __long__

Antoine Pitroud4ae97b2008-08-29 18:39:48 +00002115 was correctly parsed but parsing of subsequent arguments failed.
2116
Vinay Sajip35e3b032008-09-01 14:33:59 +00002117- Issue #2534: speed up isinstance() and issubclass() by 50-70%, so as to
Antoine Pitrou0668c622008-08-26 22:42:08 +00002118 match Python 2.5 speed despite the __instancecheck__ / __subclasscheck__
2119 mechanism. In the process, fix a bug where isinstance() and issubclass(),
2120 when given a tuple of classes as second argument, were looking up
2121 __instancecheck__ / __subclasscheck__ on the tuple rather than on each
2122 type object.

Guido van Rossumf8402962008-08-20 15:01:50 +00002269- Issue #1878: Remove Py_TPFLAGS_HAVE_VERSION_TAG from
2270 Py_TPFLAGS_DEFAULT when not building the core. This means 3rd party
2271 extensions do not automatically benefit from the class attribute
2272 cache; they will have to explicitly add Py_TPFLAGS_HAVE_VERSION_TAG
2273 to their tp_flags field if they care. This is a backwards
2274 compatibility feature; in 3.0, all types will use the cache by
2275 default.
2276
Benjamin Petersonf647dc12008-08-20 01:27:30 +00002277- Keyword arguments can now follow starred arguments. (``f(a, *args,
2278 keyword=23)`` is now valid syntax.)
2279
Thomas Heller0ad5ae02008-08-19 19:25:04 +00002280- ctypes function pointers that are COM methods have a boolean True
2281 value again.
2282
Martin v. Löwisf91d46a2008-08-12 14:49:50 +00002283- Issue #3139: Make buffer-interface thread-safe wrt. PyArg_ParseTuple,
2284 by denying s# to parse objects that have a releasebuffer procedure,
2285 and introducing s*.
2286
Georg Brandl1e13ea92008-08-11 09:07:59 +00002287- Issue #3537: Fix an assertion failure when an empty but presized dict
2288 object was stored in the freelist.
2289
Mark Dickinsonb6467572008-08-04 21:30:09 +00002290- Issue #1481296: Make long(float('nan')) and int(float('nan')) raise
2291 ValueError consistently across platforms.
2292
Amaury Forgeot d'Arc39fd6722008-07-31 21:28:03 +00002293- Issue #3479: On platforms where sizeof(int) is smaller than sizeof(long)
2294 (64bit Unix, for example), unichr() would truncate its argument and return
2295 u'\x00' for unichr(2**32). Now it properly raises an OverflowError.
2296
Neal Norwitze7d8be82008-07-31 17:17:14 +00002297- Apply security patches from Apple.
2298
Amaury Forgeot d'Arc246daed2008-07-31 00:42:16 +00002299- Issue #2542: Now that issubclass() may call arbitrary code, ensure that
2300 PyErr_ExceptionMatches returns 0 when an exception occurs there.
2301
Antoine Pitrou92f82162008-07-25 22:22:08 +00002302- Issue #1819: function calls with several named parameters are now on
2303 average 35% faster (as measured by pybench).
2304
Amaury Forgeot d'Arce4921fe2008-07-21 22:00:38 +00002305- Issue #2378: An unexpected UnboundLocalError or NameError could appear when
2306 the python debugger steps into a class statement: the free variables (local
2307 variables defined in an outer scope) would be deleted from the outer scope.
2308
Gregory P. Smith0470bab2008-07-22 04:46:32 +00002309- Issue #2620: Overflow checking when allocating or reallocating memory
2310 was not always being done properly in some python types and extension
2311 modules. PyMem_MALLOC, PyMem_REALLOC, PyMem_NEW and PyMem_RESIZE have
2312 all been updated to perform better checks and places in the code that
2313 would previously leak memory on the error path when such an allocation
2314 failed have been fixed.

2320
Benjamin Petersone977ad42008-08-20 01:42:01 +00002321- The methods ``is_in_tuple()``, ``is_vararg()``, and ``is_keywordarg()`` of
2322 symtable.Symbol have been deprecated for removal in 3.0 and the next release.
2323
Amaury Forgeot d'Arc351ffb82008-08-18 19:23:47 +00002324- Issue #2234: distutils failed for some versions of the cygwin compiler. The
2325 version reported by these tools does not necessarily follow the python
2326 version numbering scheme, so the module is less strict when parsing it.
2327
Nick Coghlanf70385a2008-08-18 12:42:46 +00002328- Issue #2235: Added Py3k warnings for types which will become unhashable
2329 under the stricter __hash__ inheritance rules in 3.0. Several types
2330 which did not meet the rules for hash invariants and were already
2331 unhashable in 3.0 have now been explicitly flagged as unhashable in
2332 2.6 as well (collections.Mapping, collections.Set, unittest.TestSuite,
2333 xml.dom.minidom.NamedNodeMap, numbers.Number, UserList.UserList)
2334
Brett Cannon88f801d2008-08-18 00:46:22 +00002335- Update __all__ for cookielib, csv, os, urllib2, and weakref to include things
2336 imported into the module but exposed as part of the module's API.
2337
Brett Cannon7b96f072008-08-18 00:41:11 +00002338- Remove an unneeded import of abc.ABCMeta from 'inspect'.

2343
Hirokazu Yamamoto41a81eb2008-08-17 13:10:46 +00002344- Issue #3575: Incremental decoder's decode function now takes bytearray
2345 by using 's*' instead of 't#'.
2346
Mark Dickinson3e4caeb2009-02-21 20:27:01 +00002347- Issue #2222: Fixed reference leak when occurred os.rename()
Hirokazu Yamamoto7f30a682008-08-17 09:46:56 +00002348 fails unicode conversion on 2nd parameter. (windows only)
2349
Facundo Batista94f243a2008-08-17 03:38:39 +00002350- Issue 2464. urllib2 now supports a malformation in the URL received
2351 in a redirect.

Brett Cannon721b1452008-08-16 22:00:27 +00002354 BaseHTTPServer, cgi (and rfc822), httplib.
Brett Cannonabe423e2008-08-16 21:47:07 +00002355
Facundo Batistaeb90b782008-08-16 14:44:07 +00002356- Issue #2776: fixed small issue when handling an URL with double slash
2357 after a 302 response in the case of not going through a proxy.
2358
Antoine Pitroub90a8be2008-08-15 21:03:21 +00002359- Issue #2676: in the email package, content-type parsing was hanging on
2360 pathological input because of quadratic or exponential behaviour of a
2361 regular expression.
2362
Antoine Pitrou11ec65d2008-08-14 21:04:30 +00002363- Issue #3476: binary buffered reading through the new "io" library is now
2364 thread-safe.
2365
Brett Cannonbf3157b2008-08-14 05:00:03 +00002366- Silence the DeprecationWarning of rfc822 when it is imported by mimetools
2367 since mimetools itself is deprecated. Because modules are cached, all
2368 subsequent imports of rfc822 will not raise a visible DeprecationWarning.
2369
Antoine Pitrou9fcd4b32008-08-11 17:21:36 +00002370- Issue #3134: shutil referenced undefined WindowsError symbol.
2371
Robert Schuppenies14646332008-08-10 11:01:53 +00002372- Issue #1342811: Fix leak in Tkinter.Menu.delete. Commands associated to
2373 menu entries were not deleted.
2374
Brett Cannon83e81842008-08-09 23:30:55 +00002375- Copied the implementation of reduce() to _functools.reduce() to have a
2376 version that did not raise a DeprecationWarning under -3.
2377
Antoine Pitrou76b8bee2008-08-09 17:27:23 +00002378- Issue #3205: When iterating over a BZ2File fails allocating memory, raise
2379 a MemoryError rather than silently stop the iteration.
2380
Guido van Rossum59ce9012008-08-09 14:55:34 +00002381- Issue #3487: sre "bytecode" validator. Passing invalid "re-bytecode"
2382 to _sre.compile() will now be rejected. This should not affect anybody
2383 since the re.compile() function never generates invalid re-bytecode.
2384
Skip Montanaroa032bf42008-08-08 22:52:51 +00002385- Issue #3436: Make csv.DictReader's fieldnames attribute a property so that
2386 upon first access it can be automatically initialized from the csv file if
2387 it wasn't initialized during instantiation.
2388
Brett Cannon3aa2a492008-08-06 22:28:09 +00002389- Issue #2338: Create imp.reload() to help with transitioning to Python 3.0 as
2390 the reload() built-in has been removed.
2391
Brett Cannon7e30b672008-08-04 21:52:25 +00002392- Changed code in the following modules/packages to remove warnings raised
Brett Cannonc1b76e42008-08-09 23:06:16 +00002393 while running under the ``-3`` flag: aifc, asynchat, asyncore, bdb, bsddb,

2401 raised an AttributeError.
2402
Benjamin Peterson01a24322008-07-28 23:35:27 +00002403- Issue #2523: Fix quadratic behaviour when read()ing a binary file without
Antoine Pitroude781a42008-08-09 12:43:23 +00002404 asking for a specific length. This problem only affected files opened
2405 using the new "io" module, not the built-in open() function.
Benjamin Peterson01a24322008-07-28 23:35:27 +00002406
Mark Dickinsonfe84cce2008-07-27 06:39:07 +00002407- Issue #3449: Update decimal module to use most recent specification
2408 (v. 1.68) and tests (v. 2.58) from IBM.
2409

2429
Antoine Pitrou5fdfa3e2008-07-25 19:42:26 +00002430- Issue #3394: zipfile.writestr sets external attributes when passed a
2431 file name rather than a ZipInfo instance, so files are extracted with
2432 mode 0600 rather than 000 under Unix.
2433
Gregory P. Smitha36f8fe2008-08-04 00:13:29 +00002434- Issue #1857: subprocess.Popen.poll gained an additional _deadstate keyword
2435 argument in python 2.5, this broke code that subclassed Popen to include its
2436 own poll method. Fixed my moving _deadstate to an _internal_poll method.

2444-------------
2445
Nick Coghlan6e8fef02008-08-18 13:14:22 +00002446- Issue #2235: the C API function PyObject_HashNotImplemented and its
2447 interaction with the tp_hash slot (added in 2.6b2) are now documented
2448
Nick Coghlan2a0c2b12008-08-04 12:47:17 +00002449- Issue #643841: The language reference now provides more detailed
2450 coverage of the lookup process for special methods. The disclaimers
2451 regarding lack of coverage of new-style classes have also been
2452 removed, since the coverage is now fairly reasonable.

2456================================
2457
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00002458*Release date: 17-Jul-2008*
2459
Raymond Hettingere3ae6552008-06-20 04:18:15 +00002460Core and Builtins
2461-----------------
2462
Georg Brandl3e483f62008-07-16 22:57:41 +00002463- Issue #3156: Fix inconsistent behavior of the bytearray type: all
2464 its methods now allow for items objects that can be converted to
2465 an integer using operator.index().
2466
Mark Dickinson64b7e502008-07-16 09:40:03 +00002467- Issue #3360: Fix incorrect parsing of '020000000000.0', which
2468 produced a ValueError instead of giving the correct float.
2469
Eric Smitha5fa5a22008-07-16 00:11:49 +00002470- Issue #3083: Add alternate (#) formatting for bin, oct, hex output
2471 for str.format(). This adds the prefix 0b, 0o, or 0x, respectively.
2472
Mark Dickinson7103aa42008-07-15 19:08:33 +00002473- Issue #3008: the float type has a new instance method 'float.hex'
2474 and a new class method 'float.fromhex' to convert floating-point
2475 numbers to and from hexadecimal strings, respectively.
2476
Nick Coghlan6d6bd442008-07-15 15:40:22 +00002477- Issue #2235: __hash__ is once again inherited by default. To allow
2478 collections.Hashable to remain meaningful in the presence of the
2479 default hash implementation (object.__hash__), it is now possible
2480 to explicit block inheritance of hash by setting __hash__=None at
2481 the Python level, or tp_hash=PyObject_HashNotImplemented at the C
2482 level.
2483
Nick Coghlanb028f502008-07-13 14:52:36 +00002484- Issue #3221: Issue a RuntimeWarning instead of raising SystemError if
2485 the parent module cannot be found while performing an absolute import.
2486 This means that an incorrectly defined __package__ attribute will
2487 now only prevent relative imports in that module rather than causing
2488 all imports from that module to fail.
2489
Nick Coghlan14ff9942008-07-08 14:21:42 +00002490- Issue #2517: Allow unicode messages in Exceptions again by correctly
2491 bypassing the instance dictionary when looking up __unicode__ on
2492 new-style classes.
2493
Amaury Forgeot d'Arcbdd941f2008-07-01 20:38:04 +00002494- Issue #3242: Fix a crash inside the print statement, if sys.stdout is
2495 set to a custom object whose write() method happens to install
2496 another file in sys.stdout.
2497
Amaury Forgeot d'Arc1f40c8a2008-06-30 22:42:40 +00002498- Issue #3088: Corrected a race condition in classes derived from
2499 threading.local: the first member set by a thread could be saved in
2500 another thread's dictionary.
2501
Mark Dickinson1ec2fcd2008-06-20 14:53:43 +00002502- Issue #3004: Minor change to slice.indices(): the start and stop
2503 arguments are now treated identically, making the behaviour easier
2504 to describe and understand. For example, slice(None, -10,
2505 1).indices(9) now returns (0, 0, 1) instead of (0, -1, 1), and
2506 slice(None, 10, -1).indices(10) returns (9, 9, -1) instead of (9,
2507 10, -1).
2508
Georg Brandl278fc502008-07-19 12:46:12 +00002509- Issue #3219: Calling a function with repeated keyword arguments,
2510 f(a=2, a=23), would not cause a syntax error. This was a regression
2511 from 2.4 caused by the switch to the new compiler.
Benjamin Peterson175e4d92008-07-01 19:34:52 +00002512
Georg Brandl278fc502008-07-19 12:46:12 +00002513- Issue #2862: Make int and float freelist management consistent with
2514 other freelists. Changes their CompactFreeList apis into
2515 ClearFreeList apis and calls them via gc.collect().
Gregory P. Smith2fe77062008-07-06 03:35:58 +00002516

2518-------
2519
Thomas Heller57adf222008-08-14 19:10:48 +00002520- Issue #3554: ctypes.string_at and ctypes.wstring_at did call Python
2521 api functions without holding the GIL, which could lead to a fatal
2522 error when they failed.
2523
Martin v. Löwisaabf4042008-08-02 07:20:25 +00002524- Issue #799428: Fix Tkinter.Misc._nametowidget to unwrap Tcl command objects.

Jesse Noller13e9d582008-07-16 14:32:36 +00002532- Issue #3125: Remove copy_reg in multiprocessing and replace it with
2533 ForkingPickler.register() to resolve conflict with ctypes.
2534
Vinay Sajip51e65192008-07-18 09:01:10 +00002535- Issue #3090: Fixed ARCHFLAGS parsing on OS/X
Jesse Noller13e9d582008-07-16 14:32:36 +00002536
Thomas Heller880f5292008-07-15 19:39:38 +00002537- Issue #3313: Fixed a crash when a failed dlopen() call does not set
2538 a valid dlerror() message.
2539
Thomas Heller2bad6572008-07-15 17:19:50 +00002540- Issue #3258: Fixed a crash when a ctypes POINTER type to an
2541 incomplete structure was created.
2542
Brett Cannon3d0b9f02008-07-13 01:15:07 +00002543- Issue #3339: dummy_thread.acquire() should not return None.
2544
Raymond Hettingerb01713e2008-07-10 14:34:57 +00002545- Issue #3285: Fractions from_float() and from_decimal() accept Integral arguments.
2546
Andrew M. Kuchlingcc3f2b12008-07-10 14:43:31 +00002547- Issue #3301: Bisect module behaved badly when lo was negative.
Raymond Hettinger3cd1e422008-07-10 14:03:19 +00002548
Amaury Forgeot d'Arc0f7cddc2008-07-06 21:34:39 +00002549- Issue #839496: SimpleHTTPServer used to open text files in text mode. This is
2550 both unnecessary (HTTP allows text content to be sent in several forms) and
Andrew M. Kuchlingcc3f2b12008-07-10 14:43:31 +00002551 wrong because the actual transmitted size could differ from the
Amaury Forgeot d'Arc0f7cddc2008-07-06 21:34:39 +00002552 content-length. The problem had been corrected in the 2.4 branch, but never
2553 merged into trunk.
2554
Georg Brandle78fbcc2008-07-05 10:13:36 +00002555- Issue #2663: add filtering capability to shutil.copytree().

2558
2559- Issue #1526: Allow more than 64k files to be added to Zip64 file.
2560
2561- Issue #1746: Correct handling of zipfile archive comments (previously

2958
Ronald Oussoren5640ce22008-06-05 12:58:24 +00002959- On MacOS X it is now possible to install the framework in 64-bit
2960 mode or even as a 4-way universal binary (that is, PPC, i386,
Georg Brandl5cc774e2008-06-11 20:28:06 +00002961 PPC64 and x86_64 support in one binary).
Ronald Oussoren5640ce22008-06-05 12:58:24 +00002962
2963 This is controlled by the configure argument ``--with-universal-archs``:
2964
2965 - ``--with-universal-archs=all``: install 4-way universal
2966
2967 - ``--with-universal-archs=32-bit``: install 2-way universal, 32-bit (the default)
2968
2969 - ``--with-universal-archs=64-bit``: install 2-way universal, 64-bit
2970
2971 This option should be used in combination with ``--enable-universalsdk=``.
2972
2973 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 +00003023- Issue #1631171: Re-implement the 'warnings' module in C (the
3024 original Python code has been kept as backup). This will allow for
3025 using the 'warning's machinery in such places as the parser where
3026 use of pure Python code is not possible. Both the ``showarning()``
3027 and ``formatwarning()`` gain an optional 'line' argument which is
3028 not called by default for backwards-compatibility reasons. Setting
3029 ``warnings.showwarning()`` to an implementation that lacks support
3030 for the ``line`` argument will raise a DeprecationWarning.

3054
Gregory P. Smithd59fefb2008-04-22 08:11:33 +00003055- The getpass module has been improved on Unix. It now uses /dev/tty
3056 by default and uses stderr instead of stdout. A GetPassWarning is
3057 issued when input echo cannot be controlled.

Georg Brandl3ee81df2008-05-17 18:14:43 +00003093- Issue #2550: The approach used by client/server code for obtaining
3094 ports to listen on in network-oriented tests has been refined in an
3095 effort to facilitate running multiple instances of the entire
3096 regression test suite in parallel without issue.
3097 test_support.bind_port() has been fixed such that it will always
3098 return a unique port -- which wasn't always the case with the
3099 previous implementation, especially if socket options had been set
3100 that affected address reuse (i.e. SO_REUSEADDR, SO_REUSEPORT). The
3101 new implementation of bind_port() will actually raise an exception
3102 if it is passed an AF_INET/SOCK_STREAM socket with either the
3103 SO_REUSEADDR or SO_REUSEPORT socket option set. Furthermore, if
3104 available, bind_port() will set the SO_EXCLUSIVEADDRUSE option on
3105 the socket it's been passed. This currently only applies to
3106 Windows. This option prevents any other sockets from binding to the
3107 host/port we've bound to, thus removing the possibility of the
3108 'non-deterministic' behaviour, as Microsoft puts it, that occurs
3109 when a second SOCK_STREAM socket binds and accepts to a host/port
3110 that's already been bound by another socket. The optional preferred
3111 port parameter to bind_port() has been removed. Under no
3112 circumstances should tests be hard coding ports!
3113
3114 test_support.find_unused_port() has also been introduced, which will
3115 pass a temporary socket object to bind_port() in order to obtain an
3116 unused port. The temporary socket object is then closed and
3117 deleted, and the port is returned. This method should only be used
3118 for obtaining an unused port in order to pass to an external program
3119 (i.e. the -accept [port] argument to openssl's s_server mode) or as
3120 a parameter to a server-oriented class that doesn't give you direct
3121 access to the underlying socket used.
3122
3123 Finally, test_support.HOST has been introduced, which should be used
3124 for the host argument of any relevant socket calls (i.e. bind and

3399Core and builtins
3400-----------------
3401
Fred Drakea8ee94b2008-03-01 02:45:07 +00003402- Issue #2051: pyc and pyo files are no longer created with permission
Barry Warsaw52973612008-03-01 02:23:38 +00003403 644. The mode is now inherited from the py file.
Christian Heimes40346852008-02-23 17:52:07 +00003404
Georg Brandlad61bc82008-02-23 15:11:18 +00003405- Issue #2067: file.__exit__() now calls subclasses' close() method.
3406
3407- Patch #1759: Backport of PEP 3129 class decorators.
Christian Heimes5224d282008-02-23 15:01:05 +00003408
Vinay Sajipb7edfc42008-04-02 21:10:23 +00003409- Issue #1881: An internal parser limit has been increased. Also see
Facundo Batistafc2d0102008-02-23 12:01:13 +00003410 issue 215555 for a discussion.
3411
Eric Smitha73fbe72008-02-23 03:09:44 +00003412- Added the future_builtins module, which contains hex() and oct().
3413 These are the PEP 3127 version of these functions, designed to be
3414 compatible with the hex() and oct() builtins from Python 3.0. They
3415 differ slightly in their output formats from the existing, unchanged
3416 Python 2.6 builtins. The expected usage of the future_builtins
3417 module is:
3418 from future_builtins import hex, oct
3419
Eric Smith7ef40bf2008-02-20 23:34:22 +00003420- Issue #1600: Modifed PyOS_ascii_formatd to use at most 2 digit
3421 exponents for exponents with absolute value < 100. Follows C99
3422 standard. This is a change on Windows, which would use 3 digits.
3423 Also, added 'n' to the formats that PyOS_ascii_formatd understands,
3424 so that any alterations it does to the resulting string will be
3425 available in stringlib/formatter.h (for float.__format__).
3426
Eric Smith5a3c1352008-02-19 13:21:56 +00003427- Implemented PEP 3101, Advanced String Formatting. This adds a new
3428 builtin format(); a format() method for str and unicode; a
3429 __format__() method to object, str, unicode, int, long, float, and
3430 datetime; the class string.Formatter; and the C API
3431 PyObject_Format().
3432
Georg Brandl3ee81df2008-05-17 18:14:43 +00003433- Fixed several potential crashes, all caused by specially crafted
3434 __del__ methods exploiting objects in temporarily inconsistent
3435 state.
Amaury Forgeot d'Arc632fad32008-02-16 20:55:24 +00003436
Vinay Sajipb7edfc42008-04-02 21:10:23 +00003437- Issue #2115: Important speedup in setting __slot__ attributes. Also
Georg Brandl3ee81df2008-05-17 18:14:43 +00003438 prevent a possible crash: an Abstract Base Class would try to access
3439 a slot on a registered virtual subclass.
Amaury Forgeot d'Arc60d6c7f2008-02-15 21:22:45 +00003440
Georg Brandl3ee81df2008-05-17 18:14:43 +00003441- Fixed repr() and str() of complex numbers with infinity or nan as
3442 real or imaginary part.
Christian Heimes2f0da532008-02-15 06:57:08 +00003443
Georg Brandl3ee81df2008-05-17 18:14:43 +00003444- Clear all free lists during a gc.collect() of the highest generation
3445 in order to allow pymalloc to free more arenas. Python may give back
3446 memory to the OS earlier.
Christian Heimes3b718a72008-02-14 12:47:33 +00003447
Georg Brandl3ee81df2008-05-17 18:14:43 +00003448- Issue #2045: Fix an infinite recursion triggered when printing a
3449 subclass of collections.defaultdict, if its default_factory is set
3450 to a bound method.
Amaury Forgeot d'Arcb01aa432008-02-08 00:56:02 +00003451
Christian Heimesf75dbef2008-02-08 00:11:31 +00003452- Fixed a minor memory leak in dictobject.c. The content of the free
3453 list was not freed on interpreter shutdown.
3454
Georg Brandl3ee81df2008-05-17 18:14:43 +00003455- Limit free list of method and builtin function objects to 256
3456 entries each.
Christian Heimes6075a822008-02-06 12:44:34 +00003457
Georg Brandl3ee81df2008-05-17 18:14:43 +00003458- Patch #1953: Added ``sys._compact_freelists()`` and the C API
3459 functions ``PyInt_CompactFreeList`` and ``PyFloat_CompactFreeList``
Christian Heimes422051a2008-02-04 18:00:12 +00003460 to compact the internal free lists of pre-allocted ints and floats.
3461
Georg Brandl3ee81df2008-05-17 18:14:43 +00003462- Issue #1983: Fixed return type of fork(), fork1() and forkpty()
3463 calls. Python expected the return type int but the fork familie
3464 returns pi_t.
Christian Heimes951cc0f2008-01-31 23:08:23 +00003465
Georg Brandl3ee81df2008-05-17 18:14:43 +00003466- Issue #1678380: Fix a bug that identifies 0j and -0j when they
3467 appear in the same code unit.
Mark Dickinson105be772008-01-31 22:17:37 +00003468
Georg Brandl3ee81df2008-05-17 18:14:43 +00003469- Issue #2025: Add tuple.count() and tuple.index() methods to comply
3470 with the collections.Sequence API.
Raymond Hettinger5b07ebc2008-02-07 00:54:20 +00003471
Georg Brandl3ee81df2008-05-17 18:14:43 +00003472- Patch #1970 by Antoine Pitrou: Speedup unicode whitespace and
3473 linebreak detection
Christian Heimes4d4f2702008-01-30 11:32:37 +00003474
Georg Brandl3ee81df2008-05-17 18:14:43 +00003475- Added ``PyType_ClearCache()`` and ``sys._clear_type_cache`` to clear
3476 the internal lookup cache for ref leak tests.
Christian Heimes908caac2008-01-27 23:34:59 +00003477
Georg Brandl3ee81df2008-05-17 18:14:43 +00003478- Patch #1473257: generator objects gain a gi_code attribute. This is
3479 the same object as the func_code attribute of the function that
3480 produced the generator.
Georg Brandl0cdf9a32008-01-26 14:14:20 +00003481
Georg Brandl3ee81df2008-05-17 18:14:43 +00003482- Issue #1920: "while 0" statements were completely removed by the
3483 compiler, even in the presence of an "else" clause, which is
3484 supposed to be run when the condition is false. Now the compiler
3485 correctly emits bytecode for the "else" suite.
Amaury Forgeot d'Arc31eaafe2008-01-24 22:59:25 +00003486
Guido van Rossumeead05f2008-01-24 18:21:02 +00003487- A few crashers fixed: weakref_in_del.py (issue #1377858);
3488 loosing_dict_ref.py (issue #1303614, test67.py);
3489 borrowed_ref_[34].py (not in tracker).
3490
Vinay Sajipd7cf32e2008-01-24 12:43:33 +00003491- Issue #1069410: The "can't load dll" message box on Windows is
Christian Heimesb2302ba2008-01-23 17:15:06 +00003492 suppressed while an extension is loaded by calling SetErrorMode in
3493 dynload_win.c. The error is still reported properly.
3494
Georg Brandl3ee81df2008-05-17 18:14:43 +00003495- Issue #1915: Python compiles with --enable-unicode=no again. However
Christian Heimes082c9b02008-01-23 14:20:50 +00003496 several extension methods and modules do not work without unicode
3497 support.
3498
Georg Brandl26543b12008-01-21 18:36:51 +00003499- Issue #1882: when compiling code from a string, encoding cookies in the
3500 second line of code were not always recognized correctly.
3501
Georg Brandl14404b62008-01-19 19:27:05 +00003502- Issue #1679: "0x" was taken as a valid integer literal.
3503
Georg Brandl6caad7d2008-01-26 14:19:22 +00003504- Issue #1865: ``bytes`` as an alias for ``str`` and b"" as an alias "" were
Christian Heimes288e89a2008-01-18 18:24:07 +00003505 added.
3506
Christian Heimesc94e2b52008-01-14 04:13:37 +00003507- sys.float_info / PyFloat_GetInfo: The floating point information
3508 object was converted from a dict to a specialized structseq object.
3509
Georg Brandl3ee81df2008-05-17 18:14:43 +00003510- Patch #1816: Added sys.flags structseq. It exposes the status of
3511 most command line arguments and PYTHON* environment variables.
Christian Heimesf31b69f2008-01-14 03:42:48 +00003512
Georg Brandl3ee81df2008-05-17 18:14:43 +00003513- Objects/structseq.c: Implemented new structseq representation. The
3514 patch makes structseqs (e.g. the return value of os.stat) more
3515 readable.
Christian Heimes9c201962008-01-14 03:33:52 +00003516
Georg Brandl3ee81df2008-05-17 18:14:43 +00003517- Patch #1700288: added a type attribute cache that caches method
3518 accesses, resulting in speedups in heavily object-oriented code.
Amaury Forgeot d'Arce4c270c2008-01-14 00:29:41 +00003519
Neal Norwitz3fc15b82008-01-10 05:42:58 +00003520- Bug #1776: __import__() no longer accepts filenames on any platform.
3521 The first parameter to __import__() must be a valid module name.
Christian Heimes3403f152008-01-09 19:56:33 +00003522
Georg Brandlaed6c662008-01-07 17:25:53 +00003523- Patch #1668: renamed THREADDEBUG envvar to PYTHONTHREADDEBUG.
3524
Georg Brandl3ee81df2008-05-17 18:14:43 +00003525- Patch #602345: Add -B command line option, PYTHONDONTWRITEBYTECODE
3526 envvar and sys.dont_write_bytecode attribute. All these can be set
3527 to forbid Python to attempt to write compiled bytecode files.
Georg Brandl2da0fce2008-01-07 17:09:35 +00003528
Georg Brandl3ee81df2008-05-17 18:14:43 +00003529- Improve some exception messages when Windows fails to load an
3530 extension module. Now we get for example '%1 is not a valid Win32
3531 application' instead of 'error code 193'.
Amaury Forgeot d'Arce0b76952008-01-04 02:04:15 +00003532
Georg Brandl3ee81df2008-05-17 18:14:43 +00003533- Bug #1481296: Fixed long(float('nan')) != 0L.

Georg Brandl3ee81df2008-05-17 18:14:43 +00003535- Issue #1640: Added math.isinf(x), math.isnan(x) and math.copysign(x,
3536 y) functions.
Christian Heimese2ca4242008-01-03 20:23:15 +00003537
Christian Heimes0a8143f2007-12-18 23:22:54 +00003538- Issue #1635: Platform independent creation and representation of NaN
Georg Brandl3ee81df2008-05-17 18:14:43 +00003539 and INF. float("nan"), float("inf") and float("-inf") now work on
3540 every platform with IEEE 754 semantics.
Christian Heimes0a8143f2007-12-18 23:22:54 +00003541
Georg Brandl3ee81df2008-05-17 18:14:43 +00003542- Compiler now generates simpler and faster code for dictionary
3543 literals. The oparg for BUILD_MAP now indicates an estimated
3544 dictionary size. There is a new opcode, STORE_MAP, for adding
3545 entries to the dictionary.

3563 running, and if the deallocation of its frames somehow calls the
3564 PyGILState_Ensure() / PyGILState_Release() functions.
Amaury Forgeot d'Arcbe49a902007-11-30 20:37:22 +00003565

Georg Brandl3ee81df2008-05-17 18:14:43 +00003579- Issue #1265: Fix a problem with sys.settrace, if the tracing
3580 function uses a generator expression when at the same time the
3581 executed code is closing a paused generator.
Amaury Forgeot d'Arc0d75f092007-11-13 21:54:28 +00003582
Raymond Hettinger1760c8a2007-11-08 02:52:43 +00003583- sets and frozensets now have an isdisjoint() method.
3584
Raymond Hettinger3f8caa32007-10-24 01:28:33 +00003585- optimize the performance of builtin.sum().
3586
Neal Norwitz44f326e2007-10-05 05:29:17 +00003587- Fix warnings found by the new version of the Coverity checker.
3588
Georg Brandl3ee81df2008-05-17 18:14:43 +00003589- The enumerate() builtin function is no longer bounded to sequences
3590 smaller than LONG_MAX. Formerly, it raised an OverflowError. Now,
3591 automatically shifts from ints to longs.
Raymond Hettinger8f669372007-10-03 21:18:11 +00003592
Georg Brandl3ee81df2008-05-17 18:14:43 +00003593- Issue #1686386: Tuple's tp_repr did not take into account the
3594 possibility of having a self-referential tuple, which is possible
3595 from C code. Nor did object's tp_str consider that a type's tp_str
3596 could do something that could lead to an inifinite recursion.
3597 Py_ReprEnter() and Py_EnterRecursiveCall(), respectively, fixed the
3598 issues.
Brett Cannon0b14f242007-09-30 19:45:10 +00003599
Georg Brandl3ee81df2008-05-17 18:14:43 +00003600- Issue #1164: It was possible to trigger deadlock when using the
3601 'print' statement to write to a file since the GIL was not released
3602 as needed. Now PyObject_Print() does the right thing along with
3603 various tp_print implementations of the built-in types and those in
3604 the collections module.

Georg Brandl3ee81df2008-05-17 18:14:43 +00003606- Issue #1147: Exceptions were directly allowing string exceptions in
3607 their throw() method even though string exceptions no longer
3608 allowed.
Brett Cannon4c20bc42007-09-11 21:02:28 +00003609

Brett Cannon1e534b52007-09-07 04:18:30 +00003613- Issue #1202533: Fix infinite recursion calls triggered by calls to
Georg Brandl3ee81df2008-05-17 18:14:43 +00003614 PyObject_Call() never calling back out to Python code to trigger
3615 recursion depth updates/checks. Required the creation of a static
3616 RuntimeError instance in case normalizing an exception put the
3617 recursion check value past its limit. Fixes crashers

Georg Brandl3ee81df2008-05-17 18:14:43 +00003634 __*__ attributes. (Some already existed, e.g., __doc__ and
3635 __name__.)
Neal Norwitz0ac60192007-05-27 04:08:54 +00003636
Neal Norwitz8b2bfbc2007-05-23 06:35:32 +00003637- Add -3 option to the interpreter to warn about features that are

Georg Brandl3ee81df2008-05-17 18:14:43 +00003644 "except E as target:". This is to provide forwards compatibility
3645 with Python 3.0.
Collin Winter62903052007-05-18 23:11:24 +00003646
Brett Cannon229cee22007-05-05 01:34:02 +00003647- Deprecate BaseException.message as per PEP 352.

3665
Guido van Rossum143b5642007-03-23 04:58:42 +00003666- Bug #1683368: The object.__init__() and object.__new__() methods are
3667 now stricter in rejecting excess arguments. The only time when
3668 either allows excess arguments is when it is not overridden and the
3669 other one is. For backwards compatibility, when both are
3670 overridden, it is a deprecation warning (for now; maybe a Py3k
Guido van Rossum234b1ff2007-03-23 19:39:01 +00003671 warning later). Also, type.__init__() insists on the same signature
3672 as supported by type.__new__().
Guido van Rossum143b5642007-03-23 04:58:42 +00003673
Georg Brandl3ee81df2008-05-17 18:14:43 +00003674- Patch #1675423: PyComplex_AsCComplex() now tries to convert an
3675 object to complex using its __complex__() method before falling back
3676 to the __float__() method. Therefore, the functions in the cmath
3677 module now can operate on objects that define a __complex__()
3678 method.

3695
Georg Brandl7b9c5552007-03-12 14:30:05 +00003696- Bug #1678647: write a newline after printing an exception in any
3697 case, even when converting the value to a string failed.
3698
Georg Brandl871f1bc2007-03-12 13:17:36 +00003699- The dir() function has been extended to call the __dir__() method on
Georg Brandl3ee81df2008-05-17 18:14:43 +00003700 its argument, if it exists. If not, it will work like before. This
3701 allows customizing the output of dir() in the presence of a
3702 __getattr__().
Georg Brandl871f1bc2007-03-12 13:17:36 +00003703
Collin Winter276887b2007-03-12 16:11:39 +00003704- Patch #922167: Python no longer segfaults when faced with infinitely
3705 self-recursive reload() calls (as reported by bug #742342).
3706

3712 raising a ValueError.
Collin Wintere38051d2007-03-09 20:33:07 +00003713
Georg Brandlaa2321b2007-03-07 00:40:28 +00003714- Patch #703779: unset __file__ in __main__ after running a file. This
Georg Brandl3ee81df2008-05-17 18:14:43 +00003715 makes the filenames the warning module prints much more sensible
3716 when a PYTHONSTARTUP file is used.
Georg Brandlaa2321b2007-03-07 00:40:28 +00003717

Georg Brandl0fca97a2007-03-05 22:28:08 +00003729- Patch #1674228: when assigning a slice (old-style), check for the
3730 sq_ass_slice instead of the sq_slice slot.
3731
Georg Brandl3ee81df2008-05-17 18:14:43 +00003732- When printing an unraisable error, don't print exceptions. before

Georg Brandl3ee81df2008-05-17 18:14:43 +00004358- unittest now verifies more of its assumptions. In particular,
4359 TestCase and TestSuite subclasses (not instances) are no longer
4360 accepted in TestSuite.addTest(). This should cause no
4361 incompatibility since it never made sense with ordinary subclasses
4362 -- the failure just occurred later, with a more cumbersome
4363 exception.

Georg Brandl3ee81df2008-05-17 18:14:43 +00004644- Issue #829951: In the smtplib module, SMTP.starttls() now complies
4645 with RFC 3207 and forgets any knowledge obtained from the server not
4646 obtained from the TLS negotiation itself. Patch contributed by Bill
4647 Fenner.
Gregory P. Smith2b3ba582008-01-17 08:03:17 +00004648
Georg Brandl3ee81df2008-05-17 18:14:43 +00004649- Issue #1339: The smtplib.SMTP class has been refactored a bit such
Gregory P. Smithbde4ae42008-01-17 08:35:49 +00004650 that the SMTP.starttls() caller no longer needs to call ehlo()
4651 beforehand. SMTP.starttls() now raises an exception of the server
Georg Brandl3ee81df2008-05-17 18:14:43 +00004652 does not claim to support starttls. Adds the
4653 SMTP.ehlo_or_helo_if_needed() method. Patch contributed by Bill

4734 complex, tuple, list, dict, set, and frozenset. Formerly, it would
4735 silently miscode subclasses of those types. Now, it raises a

Georg Brandl3ee81df2008-05-17 18:14:43 +00004752 time so that opening a database previously created with the DB_DUP
4753 or DB_DUPSORT flag set will keep the proper behavior on subsequent
4754 opens. Specifically: dictionary assignment to a DB object will
4755 replace all values for a given key when the database allows
4756 duplicate values. DB users should use DB.put(k, v) when they want
4757 to store duplicates; not DB[k] = v.
Gregory P. Smithec10a4a2007-11-05 02:32:26 +00004758

4764 characters with ASCII value less than 32. Also, it correctly quotes
4765 dots only if they occur on a single line, as opposed to the previous
4766 behavior of quoting dots if they are the second character of any
4767 line.
Georg Brandl4aef7272007-03-13 22:49:43 +00004768

Georg Brandl3ee81df2008-05-17 18:14:43 +00005097- ``PySet_Add()`` can now modify a newly created frozenset. Similarly
5098 to ``PyTuple_SetItem``, it can be used to populate a brand new
5099 frozenset; but it does not steal a reference to the added item.

Georg Brandl3ee81df2008-05-17 18:14:43 +00005103- Backport of PyUnicode_FromString(), _FromStringAndSize(), _Format
5104 and _FormatV from Python 3.0. Made PyLong_AsSsize_t and
5105 PyLong_FromSsize_t public functions.
Georg Brandl6caad7d2008-01-26 14:19:22 +00005106
5107- Patch #1720595: add T_BOOL to the range of structmember types.
5108
5109- Issue #1534: Added ``PyFloat_GetMax()``, ``PyFloat_GetMin()`` and
5110 ``PyFloat_GetInfo()`` to the float API.
5111
Georg Brandl3ee81df2008-05-17 18:14:43 +00005112- Issue #1521: On 64bit platforms, using PyArgs_ParseTuple with the t#
5113 of w# format code incorrectly truncated the length to an int, even
5114 when PY_SSIZE_T_CLEAN is set. The str.decode method used to return
5115 incorrect results with huge strings.
Georg Brandl6caad7d2008-01-26 14:19:22 +00005116
Georg Brandl3ee81df2008-05-17 18:14:43 +00005117- Issue #1629: Renamed Py_Size, Py_Type and Py_Refcnt to Py_SIZE,
5118 Py_TYPE and Py_REFCNT.
Georg Brandl6caad7d2008-01-26 14:19:22 +00005119
Georg Brandl3ee81df2008-05-17 18:14:43 +00005120- PEP 3123: Provide forward compatibility with Python 3.0, while
5121 keeping backwards compatibility. Add Py_Refcnt, Py_Type, Py_Size,
5122 and PyVarObject_HEAD_INIT.
Georg Brandl6caad7d2008-01-26 14:19:22 +00005123
Georg Brandl3ee81df2008-05-17 18:14:43 +00005124- Py_ssize_t fields work in structmember when HAVE_LONG_LONG is not
5125 defined.
Georg Brandl6caad7d2008-01-26 14:19:22 +00005126
5127- Patch #1733960: Allow T_LONGLONG to accept ints.
5128
5129- T_PYSSIZET can now be used in PyMemberDef lists for Py_ssize_t members.
5130
Christian Heimes000a0742008-01-03 22:16:32 +00005131- Added a new API function ``PyImport_ImportModuleNoBlock``.
5132
Georg Brandl6caad7d2008-01-26 14:19:22 +00005133- Bug #1637022: Prefix AST symbols with _Py_.
5134
5135- Fix some leftovers from the conversion from int to Py_ssize_t
5136 (relevant to strings and sequences of more than 2**31 items).
5137
5138- Make _PyGILState_NoteThreadState() static, it was not used anywhere
5139 outside of pystate.c and should not be necessary.
5140
Georg Brandl3ee81df2008-05-17 18:14:43 +00005141- ``PyImport_Import`` and ``PyImport_ImportModule`` now always do
5142 absolute imports. In earlier versions they might have used relative
5143 imports under some conditions.
Christian Heimes000a0742008-01-03 22:16:32 +00005144
Georg Brandl3ee81df2008-05-17 18:14:43 +00005145- Added case insensitive comparison methods ``PyOS_stricmp(char*,
5146 char*)`` and ``PyOS_strnicmp(char*, char*, Py_ssize_t)``.
Christian Heimes000a0742008-01-03 22:16:32 +00005147
Georg Brandl3ee81df2008-05-17 18:14:43 +00005148- Bug #1542693: remove semi-colon at end of PyImport_ImportModuleEx
5149 macro so it can be used as an expression.

Georg Brandl3ee81df2008-05-17 18:14:43 +00005155- Patch #1706: Drop support for Win9x, WinME and NT4. Python now
5156 requires Windows 2000 or greater. The _WINVER and NTDDI_VERSION
5157 macros are set to Win2k for x86/32bit builds and WinXP for AMD64
5158 builds.
Christian Heimes95d64472008-02-09 19:55:22 +00005159
Georg Brandl3ee81df2008-05-17 18:14:43 +00005160- Conditionalize definition of _CRT_SECURE_NO_DEPRECATE and

Brett Cannon791d56f2007-05-31 19:40:42 +00005171- buildtools now raises a DeprecationWarning.
5172
Georg Brandl3ee81df2008-05-17 18:14:43 +00005173- Removed the macfs module. It had been deprecated since Python 2.5.
5174 This lead to the deprecation of macostools.touched() as it relied
5175 solely on macfs and was a no-op under OS X.
