Eric Smithee931b72010-01-27 00:28:29 +000015- Issue #7766: Change sys.getwindowsversion() return value to a named
16 tuple and add the additional members returned in an OSVERSIONINFOEX
17 structure. The new members are service_pack_major, service_pack_minor,
18 suite_mask, and product_type.

Antoine Pitroue80a6a42010-01-17 12:26:20 +000020- Issue #7561: Operations on empty bytearrays (such as `int(bytearray())`)
21 could crash in many places because of the PyByteArray_AS_STRING() macro
22 returning NULL. The macro now returns a statically allocated empty
23 string instead.
24
Antoine Pitrou64672132010-01-13 07:55:48 +000025- Issue #7622: Improve the split(), rsplit(), splitlines() and replace()

30 alpha 2, including: (1) a serious 'wrong output' bug that could
31 occur for long (> 40 digit) input strings, (2) a crash in dtoa.c
32 that occurred in debug builds when parsing certain long numeric
Mark Dickinson23df3d22010-01-17 13:37:57 +000033 strings corresponding to subnormal values, (3) a memory leak for
34 some values large enough to cause overflow, and (4) a number of
35 flaws that could lead to incorrectly rounded results.

53 the release file is empty.
54
Tarek Ziadéf14c7fc2010-01-24 00:33:32 +000055- Issue #7748: Since unicode values are supported for some metadata options
56 in Distutils, the DistributionMetadata get_* methods will now return an utf-8
57 encoded string for them. This ensure that the upload and register commands
58 send the right values to PyPI without any error.

Benjamin Peterson4f51baf2009-12-05 18:40:02 +0000113What's New in Python 2.7 alpha 2?
114=================================
115
Benjamin Petersonaa7e51f2010-01-09 16:34:06 +0000116*Release date: 2010-01-09*

118Core and Builtins
119-----------------
120
Benjamin Petersonecdae192010-01-04 00:43:01 +0000121- The __complex__ method is now looked up on the class of instances to make it
122 consistent with other special methods.
123
Antoine Pitrou5b7139a2010-01-02 21:12:58 +0000124- Issue #7462: Implement the stringlib fast search algorithm for the `rfind`,
125 `rindex`, `rsplit` and `rpartition` methods. Patch by Florent Xicluna.
126
Mark Dickinson1b34d252010-01-01 17:27:30 +0000127- Issue #5080: A number of functions and methods previously produced a
128 DeprecationWarning when passed a float argument where an integer was
129 expected. These functions and methods now raise TypeError instead.
130 The majority of the effects of this change are in the extension
131 modules, but some core functions and methods are affected: notably
132 the 'chr', 'range' and 'xrange' builtins, and many unicode/str
133 methods.
134
Benjamin Peterson0f02d392009-12-30 19:34:10 +0000135- Issue #7604: Deleting an unset slotted attribute did not raise an
136 AttributeError.

143
Amaury Forgeot d'Arc8645a5c2009-12-29 22:03:38 +0000144- Issue #7413: Passing '\0' as the separator to datetime.datetime.isoformat()
145 used to drop the time part of the result.
146
Mark Dickinson46572832009-12-27 14:55:57 +0000147- Issue #1811: improve accuracy and cross-platform consistency for
148 true division of integers: the result of a/b is now correctly
149 rounded for ints a and b (at least on IEEE 754 platforms), and in
150 particular does not depend on the internal representation of a long.
151
Ezio Melottif84caf42009-12-24 22:25:17 +0000152- Issue #6108: unicode(exception) and str(exception) should return the same
153 message when only __str__ (and not __unicode__) is overridden in the subclass.
154
Ronald Oussoren92919a62009-12-24 13:30:58 +0000155- Issue #6834: replace the implementation for the 'python' and 'pythonw'
156 executables on OSX.
157
158 These executables now work properly with the arch(1) command:
159 ``arch -ppc python`` will start a universal binary version of python
160 in PPC mode (unlike previous releases).
161
R. David Murray0a0a1a82009-12-14 16:28:26 +0000162- Issue #1680159: unicode coercion during an 'in' operation no longer masks
163 the underlying error when the coercion fails for the left hand operand.
164
Benjamin Peterson4895af42009-12-13 16:36:53 +0000165- Issue #7491: Metaclass's __cmp__ method was ignored.
166
Antoine Pitrou2a08b422009-12-13 16:18:14 +0000167- Issue #7466: segmentation fault when the garbage collector is called

176 by Arfrever.
177
Antoine Pitrou80157252010-01-08 19:20:17 +0000178- Issue #7092: Remove py3k warning when importing cPickle. 2to3 handles
179 renaming of `cPickle` to `pickle`. The warning was annoying since there's
180 no alternative to cPickle if you care about performance. Patch by Florent
181 Xicluna.
182
Antoine Pitrou0d423b82010-01-07 17:46:49 +0000183- Issue #7455: Fix possible crash in cPickle on invalid input. Patch by

191 speedups by wrapping it in an `io.BufferedReader`. Patch by Nir Aides.
192
193- Issue #3972: httplib.HTTPConnection now accepts an optional source_address

Benjamin Petersonddd392c2009-12-13 19:19:07 +0000214- Issue #7349: Make methods of file objects in the io module accept None as an
215 argument where file-like objects (ie StringIO and BytesIO) accept them to mean
216 the same as passing no argument.
217
Benjamin Petersonc4771d22009-12-13 17:31:31 +0000218- Issue #7348: StringIO.StringIO.readline(-1) now acts as if it got no argument

308 on MacOSX 10.6.
309
Mark Dickinsonb678de82009-11-19 18:41:49 +0000310- Issue #7117: repr(x) for a float x returns a result based on the
311 shortest decimal string that's guaranteed to round back to x under
312 correct rounding (with round-half-to-even rounding mode).
313 Previously it gave a string based on rounding x to 17 decimal digits.
314 repr(x) for a complex number behaves similarly. On platforms where
315 the correctly-rounded strtod and dtoa code is not supported (see below),
316 repr is unchanged.
317
318- Issue #7117: On almost all platforms: float-to-string and
319 string-to-float conversions within Python are now correctly rounded.
320 Places these conversions occur include: str for floats and complex
321 numbers; the float and complex constructors; old-style and new-style
322 numeric formatting; serialization and deserialization of floats and
323 complex numbers using marshal, pickle and json; parsing of float and
324 imaginary literals in Python code; Decimal-to-float conversion.
325
326 The conversions use a Python-adapted version of David Gay's
327 well-known dtoa.c, providing correctly-rounded strtod and dtoa C
328 functions. This code is supported on Windows, and on Unix-like
329 platforms using gcc, icc or suncc as the C compiler. There may be a
330 small number of platforms on which correct operation of this code
331 cannot be guaranteed, so the code is not used: notably, this applies
332 to platforms where the C double format is not IEEE 754 binary64, and
333 to platforms on x86 hardware where the x87 FPU is set to 64-bit
334 precision and Python's configure script is unable to determine how
335 to change the FPU precision. On these platforms conversions use the
336 platform strtod and dtoa, as before.
337
Mark Dickinsonbd15a062009-11-18 19:33:35 +0000338- Issue #7117: Backport round implementation from Python 3.x. round
Mark Dickinsonb678de82009-11-19 18:41:49 +0000339 now uses the correctly-rounded string <-> float conversions
340 described above (when available), and so produces correctly rounded
341 results that will display nicely under the float repr. There are
342 two related small changes: (1) round now accepts any class with an
343 __index__ method for its second argument (but no longer accepts
Mark Dickinsonbd15a062009-11-18 19:33:35 +0000344 floats for the second argument), and (2) an excessively large second
345 integer argument (e.g., round(1.234, 10**100)) no longer raises an
346 exception.

Eric Smitha985a3a2009-05-05 18:26:08 +0000494- Issue #5920: For float.__format__, change the behavior with the
495 empty presentation type (that is, not one of 'e', 'f', 'g', or 'n')
496 to be like 'g' but with at least one decimal point and with a
497 default precision of 12. Previously, the behavior the same but with
498 a default precision of 6. This more closely matches str(), and
499 reduces surprises when adding alignment flags to the empty
500 presentation type. This also affects the new complex.__format__ in
501 the same way.

Benjamin Petersone18ef192009-01-20 14:21:16 +0000611- Issue #4978: Passing keyword arguments as unicode strings is now allowed.
612
Georg Brandl29c6a282009-04-05 20:23:13 +0000613- Issue #1242657: the __len__() and __length_hint__() calls in several tools
Raymond Hettingerb5163702009-02-02 21:50:13 +0000614 were suppressing all exceptions. These include list(), filter(), map(),
615 zip(), and bytearray().
616
Benjamin Peterson596d3062009-01-19 15:42:23 +0000617- os.ftruncate raises OSErrors instead of IOErrors for consistency with other os
618 functions.
619
Benjamin Peterson5848d1f2009-01-19 00:08:08 +0000620- Issue #4991: Passing invalid file descriptors to io.FileIO now raises an

624
Antoine Pitrouc2f02212009-01-13 23:13:52 +0000625- Issue #4935: The overflow checking code in the expandtabs() method common
626 to str, bytes and bytearray could be optimized away by the compiler, letting
627 the interpreter segfault instead of raising an error.
628
Amaury Forgeot d'Arca40d5732009-01-12 23:36:55 +0000629- Issue #3720: Fix a crash when an iterator modifies its class and removes its

635
Antoine Pitrou4c5ecb72009-01-09 21:40:55 +0000636- Issue #4074: Change the criteria for doing a full garbage collection (i.e.
637 collecting the oldest generation) so that allocating lots of objects without
638 destroying them does not show quadratic performance. Based on a proposal by
Benjamin Petersond50a5d52009-07-13 00:03:20 +0000639 Martin von Löwis at

643
Antoine Pitroue96d4ea2009-01-06 18:10:47 +0000644- Issue #1180193: When importing a module from a .pyc (or .pyo) file with
645 an existing .py counterpart, override the co_filename attributes of all
646 code objects if the original filename is obsolete (which can happen if the
647 file has been renamed, moved, or if it is accessed through different paths).
648 Patch by Ziga Seilnacht and Jean-Paul Calderone.
649
Martin v. Löwis5344c992009-01-02 20:32:55 +0000650- Issue #4075: Use OutputDebugStringW in Py_FatalError.

Hirokazu Yamamoto99a1b202009-01-01 15:45:39 +0000652- Issue #4797: IOError.filename was not set when _fileio.FileIO failed to open
653 file with `str' filename on Windows.
654
Antoine Pitrouaa687902009-01-01 14:11:22 +0000655- Issue #3680: Reference cycles created through a dict, set or deque iterator

657
Nick Coghlan180e4002008-12-30 01:18:48 +0000658- Issue #4701: PyObject_Hash now implicitly calls PyType_Ready on types
659 where the tp_hash and tp_dict slots are both NULL.
660
Benjamin Peterson7af65562008-12-29 17:56:58 +0000661- Issue #4764: With io.open, IOError.filename is set when trying to open a

669
Skip Montanarof205c132008-12-23 03:30:15 +0000670- Added test case to ensure attempts to read from a file opened for writing

684
Jeffrey Yasskinffd42cf2008-12-10 07:35:02 +0000685- Issue #4597: Fixed several opcodes that weren't always propagating
686 exceptions.
687
Mark Dickinson826f3fe2008-12-05 21:55:28 +0000688- Issue #4445: Replace "sizeof(PyStringObject)" with
689 "offsetof(PyStringObject, ob_sval) + 1" when allocating memory for
690 str instances. On a typical machine this saves 3 bytes of memory
691 (on average) per string allocation.
692
Amaury Forgeot d'Arcdc619012008-11-22 20:01:18 +0000693- Issue #3996: On Windows, the PyOS_CheckStack function would cause the
694 interpreter to abort ("Fatal Python error: Could not reset the stack!")
695 instead of throwing a MemoryError.
696
Raymond Hettinger7989a4d2008-12-03 15:42:10 +0000697- Issue #3689: The list reversed iterator now supports __length_hint__
698 instead of __len__. Behavior now matches other reversed iterators.
699
Benjamin Petersonc078f922008-11-21 22:27:24 +0000700- Issue #4367: Python would segfault during compiling when the unicodedata
701 module couldn't be imported and \N escapes were present.
702
Vinay Sajip213faca2008-12-03 23:22:58 +0000703- Issue #4233: Changed semantic of ``_fileio.FileIO``'s ``close()``
Amaury Forgeot d'Arc32265652008-11-20 23:34:31 +0000704 method on file objects with closefd=False. The file descriptor is still
705 kept open but the file object behaves like a closed file. The ``FileIO``
706 object also got a new readonly attribute ``closefd``.
707
Benjamin Peterson46cc6d12008-11-19 21:49:09 +0000708- Issue #4348: Some bytearray methods returned that didn't cause any change to
709 the bytearray, returned the same bytearray instead of a copy.
710
Amaury Forgeot d'Arc7cfe7ea2008-11-18 22:19:37 +0000711- Issue #4317: Fixed a crash in the imageop.rgb2rgb8() function.
712

Benjamin Peterson6624a9f2008-11-03 15:14:51 +0000715- Issue #4048: The parser module now correctly validates relative imports.
716
Benjamin Petersondcee09d2008-10-31 02:16:05 +0000717- Issue #4225: ``from __future__ import unicode_literals`` didn't work in an
718 exec statement.
719
Amaury Forgeot d'Arc69a9c5b2008-10-30 21:18:34 +0000720- Issue #4176: Fixed a crash when pickling an object which ``__reduce__``
721 method does not return iterators for the 4th and 5th items.
722
Benjamin Petersonbdca9422008-10-26 20:21:13 +0000723- Issue #4209: Enabling unicode_literals and the print_function in the same
724 __future__ import didn't work.
725
Benjamin Peterson399b1fe2008-10-25 02:53:28 +0000726- Using ``nonlocal`` as a variable name will now raise a Py3k SyntaxWarning
Georg Brandl7fb00ad2008-10-25 07:00:52 +0000727 because it is a reserved word in 3.x.
Benjamin Peterson399b1fe2008-10-25 02:53:28 +0000728
Hirokazu Yamamoto10a018c2008-10-09 10:00:30 +0000729- On windows, os.chdir given unicode was not working if GetCurrentDirectoryW
730 returned a path longer than MAX_PATH. (But It's doubtful this code path is
731 really executed because I cannot move to such directory on win2k)
732
Amaury Forgeot d'Arcd78b9dc2008-10-07 20:32:10 +0000733- Issue #4069: When set.remove(element) is used with a set element, the element
734 is temporarily replaced with an equivalent frozenset. But the eventual
735 KeyError would always report the empty frozenset([]) as the missing key. Now
736 it correctly refers to the initial element.
737
Antoine Pitrouae5bece2008-12-06 21:29:24 +0000738- Issue #4509: Various issues surrounding resize of bytearray objects to
739 which there are buffer exports.

749
Matthias Klose91a3b9e2009-04-05 21:19:13 +0000750- Issue #1113244: Py_XINCREF, Py_DECREF, Py_XDECREF: Add `do { ... } while (0)'
751 to avoid compiler warnings.

Gregory P. Smith2b3eb372009-04-05 23:48:26 +0000753- Issue #5705: os.setuid() would not accept values > 2**31-1 but pwd.getpwnam()
754 returned them on 64bit platforms.
755
Walter Dörwalded960ac2009-05-03 22:36:33 +0000756- Issue #5108: Handle %s like %S and %R in PyUnicode_FromFormatV(): Call
757 PyUnicode_DecodeUTF8() once, remember the result and output it in a second
758 step. This avoids problems with counting UTF-8 bytes that ignores the effect
759 of using the replace error handler in PyUnicode_DecodeUTF8().
760
Walter Dörwald726ba8e2009-05-06 14:32:35 +0000761- Issue #3739: The unicode-internal encoder now reports the number of characters
762 consumed like any other encoder (instead of the number of bytes).
763
Benjamin Peterson91c12eb2009-12-03 02:52:39 +0000764- Issue #2422: When compiled with the ``--with-valgrind`` option, the
765 pymalloc allocator will be automatically disabled when running under
766 Valgrind. This gives improved memory leak detection when running
767 under Valgrind, while taking advantage of pymalloc at other times.

2148
Amaury Forgeot d'Arc05e34492008-09-10 22:04:45 +00002149- Issue #3743: In a few places, PY_FORMAT_SIZE_T was incorrectly used with
2150 PyString_FromFormat or PyErr_Format to display size_t values. The macro
2151 PY_FORMAT_SIZE_T is designed to select the correct format for the OS
2152 ``printf`` function, whereas PyString_FromFormat has an independent
2153 implementation and uses "%zd" on all platforms for size_t values.
2154 This makes a difference on win64, where ``printf`` needs "%Id" to display
2155 64bit values.

Benjamin Peterson97179b02008-09-09 20:55:01 +00002157- Issue #3634: _weakref.ref(Exception).__init__() gave invalid return value on

2161 object; previously an int would be returned for small values. the __long__

Vinay Sajip35e3b032008-09-01 14:33:59 +00002171 PyArg_ParseTuple and friends, which occurred when the argument for "s*"
Antoine Pitroud4ae97b2008-08-29 18:39:48 +00002172 was correctly parsed but parsing of subsequent arguments failed.
2173
Vinay Sajip35e3b032008-09-01 14:33:59 +00002174- Issue #2534: speed up isinstance() and issubclass() by 50-70%, so as to
Antoine Pitrou0668c622008-08-26 22:42:08 +00002175 match Python 2.5 speed despite the __instancecheck__ / __subclasscheck__
2176 mechanism. In the process, fix a bug where isinstance() and issubclass(),
2177 when given a tuple of classes as second argument, were looking up
2178 __instancecheck__ / __subclasscheck__ on the tuple rather than on each
2179 type object.

Jesse Noller438195f2009-01-18 21:04:36 +00002274- Issue #4301: Patch the logging module to add processName support, remove
2275 _check_logger_class from multiprocessing.
2276
Amaury Forgeot d'Arc293924b2008-09-02 23:19:56 +00002277- Issue #2975: When compiling several extension modules with Visual Studio 2008
2278 from the same python interpreter, some environment variables would grow
2279 without limit.
2280
Benjamin Peterson37346b22008-08-23 20:27:43 +00002281- Issue #3643: Added a few more checks to _testcapi to prevent segfaults by
2282 exploitation of poor argument checking.
2283

2288
Gerhard Häringe6872eb2008-09-12 22:33:22 +00002289- Issue #3846: Release the GIL during sqlite3_prepare calls. This improves

2297 wrapper for warnings.catch_warnings() that makes it easier to check
2298 that expected warning messages are being reported.
2299
Amaury Forgeot d'Arcfeb8cad2008-09-06 20:53:51 +00002300- Issue #3796: Some tests functions were not enabled in test_float.

Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00002318What's New in Python 2.6 beta 3?
2319================================
2320
Barry Warsaw07a4a382008-08-21 01:15:08 +00002321*Release date: 20-Aug-2008*
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00002322
2323Core and Builtins
2324-----------------
2325
Guido van Rossumf8402962008-08-20 15:01:50 +00002326- Issue #1878: Remove Py_TPFLAGS_HAVE_VERSION_TAG from
2327 Py_TPFLAGS_DEFAULT when not building the core. This means 3rd party
2328 extensions do not automatically benefit from the class attribute
2329 cache; they will have to explicitly add Py_TPFLAGS_HAVE_VERSION_TAG
2330 to their tp_flags field if they care. This is a backwards
2331 compatibility feature; in 3.0, all types will use the cache by
2332 default.
2333
Benjamin Petersonf647dc12008-08-20 01:27:30 +00002334- Keyword arguments can now follow starred arguments. (``f(a, *args,
2335 keyword=23)`` is now valid syntax.)
2336
Thomas Heller0ad5ae02008-08-19 19:25:04 +00002337- ctypes function pointers that are COM methods have a boolean True
2338 value again.
2339
Martin v. Löwisf91d46a2008-08-12 14:49:50 +00002340- Issue #3139: Make buffer-interface thread-safe wrt. PyArg_ParseTuple,
2341 by denying s# to parse objects that have a releasebuffer procedure,
2342 and introducing s*.
2343
Georg Brandl1e13ea92008-08-11 09:07:59 +00002344- Issue #3537: Fix an assertion failure when an empty but presized dict
2345 object was stored in the freelist.
2346
Mark Dickinsonb6467572008-08-04 21:30:09 +00002347- Issue #1481296: Make long(float('nan')) and int(float('nan')) raise
2348 ValueError consistently across platforms.
2349
Amaury Forgeot d'Arc39fd6722008-07-31 21:28:03 +00002350- Issue #3479: On platforms where sizeof(int) is smaller than sizeof(long)
2351 (64bit Unix, for example), unichr() would truncate its argument and return
2352 u'\x00' for unichr(2**32). Now it properly raises an OverflowError.
2353
Neal Norwitze7d8be82008-07-31 17:17:14 +00002354- Apply security patches from Apple.
2355
Amaury Forgeot d'Arc246daed2008-07-31 00:42:16 +00002356- Issue #2542: Now that issubclass() may call arbitrary code, ensure that
2357 PyErr_ExceptionMatches returns 0 when an exception occurs there.
2358
Antoine Pitrou92f82162008-07-25 22:22:08 +00002359- Issue #1819: function calls with several named parameters are now on
2360 average 35% faster (as measured by pybench).
2361
Amaury Forgeot d'Arce4921fe2008-07-21 22:00:38 +00002362- Issue #2378: An unexpected UnboundLocalError or NameError could appear when
2363 the python debugger steps into a class statement: the free variables (local
2364 variables defined in an outer scope) would be deleted from the outer scope.
2365
Gregory P. Smith0470bab2008-07-22 04:46:32 +00002366- Issue #2620: Overflow checking when allocating or reallocating memory
2367 was not always being done properly in some python types and extension
2368 modules. PyMem_MALLOC, PyMem_REALLOC, PyMem_NEW and PyMem_RESIZE have
2369 all been updated to perform better checks and places in the code that
2370 would previously leak memory on the error path when such an allocation
2371 failed have been fixed.
2372
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00002373Library
2374-------
2375
Hirokazu Yamamoto838c79f2008-08-20 13:14:07 +00002376- Issue #3612: Added some missing basic types in ctypes.wintypes.
2377
Benjamin Petersone977ad42008-08-20 01:42:01 +00002378- The methods ``is_in_tuple()``, ``is_vararg()``, and ``is_keywordarg()`` of
2379 symtable.Symbol have been deprecated for removal in 3.0 and the next release.
2380
Amaury Forgeot d'Arc351ffb82008-08-18 19:23:47 +00002381- Issue #2234: distutils failed for some versions of the cygwin compiler. The
2382 version reported by these tools does not necessarily follow the python
2383 version numbering scheme, so the module is less strict when parsing it.
2384
Nick Coghlanf70385a2008-08-18 12:42:46 +00002385- Issue #2235: Added Py3k warnings for types which will become unhashable
2386 under the stricter __hash__ inheritance rules in 3.0. Several types
2387 which did not meet the rules for hash invariants and were already
2388 unhashable in 3.0 have now been explicitly flagged as unhashable in
2389 2.6 as well (collections.Mapping, collections.Set, unittest.TestSuite,
2390 xml.dom.minidom.NamedNodeMap, numbers.Number, UserList.UserList)
2391
Brett Cannon88f801d2008-08-18 00:46:22 +00002392- Update __all__ for cookielib, csv, os, urllib2, and weakref to include things
2393 imported into the module but exposed as part of the module's API.
2394
Brett Cannon7b96f072008-08-18 00:41:11 +00002395- Remove an unneeded import of abc.ABCMeta from 'inspect'.
2396
Brett Cannon46225e72008-08-18 00:36:52 +00002397- Remove unneeded imports of 'sys' and 'warnings' from 'io'.

Brett Cannon25c9d6a2008-08-17 22:10:11 +00002399- Remove unneeded imports of 'warnings' from shelve, filecmp, and dummy_thread.
2400
Hirokazu Yamamoto41a81eb2008-08-17 13:10:46 +00002401- Issue #3575: Incremental decoder's decode function now takes bytearray
2402 by using 's*' instead of 't#'.
2403
Mark Dickinson3e4caeb2009-02-21 20:27:01 +00002404- Issue #2222: Fixed reference leak when occurred os.rename()
Hirokazu Yamamoto7f30a682008-08-17 09:46:56 +00002405 fails unicode conversion on 2nd parameter. (windows only)
2406
Facundo Batista94f243a2008-08-17 03:38:39 +00002407- Issue 2464. urllib2 now supports a malformation in the URL received
2408 in a redirect.
2409
Brett Cannonabe423e2008-08-16 21:47:07 +00002410- Silence the DeprecationWarning raised when importing mimetools in
Brett Cannon721b1452008-08-16 22:00:27 +00002411 BaseHTTPServer, cgi (and rfc822), httplib.
Brett Cannonabe423e2008-08-16 21:47:07 +00002412
Facundo Batistaeb90b782008-08-16 14:44:07 +00002413- Issue #2776: fixed small issue when handling an URL with double slash
2414 after a 302 response in the case of not going through a proxy.
2415
Antoine Pitroub90a8be2008-08-15 21:03:21 +00002416- Issue #2676: in the email package, content-type parsing was hanging on
2417 pathological input because of quadratic or exponential behaviour of a
2418 regular expression.
2419
Antoine Pitrou11ec65d2008-08-14 21:04:30 +00002420- Issue #3476: binary buffered reading through the new "io" library is now
2421 thread-safe.
2422
Brett Cannonbf3157b2008-08-14 05:00:03 +00002423- Silence the DeprecationWarning of rfc822 when it is imported by mimetools
2424 since mimetools itself is deprecated. Because modules are cached, all
2425 subsequent imports of rfc822 will not raise a visible DeprecationWarning.
2426
Antoine Pitrou9fcd4b32008-08-11 17:21:36 +00002427- Issue #3134: shutil referenced undefined WindowsError symbol.
2428
Robert Schuppenies14646332008-08-10 11:01:53 +00002429- Issue #1342811: Fix leak in Tkinter.Menu.delete. Commands associated to
2430 menu entries were not deleted.
2431
Brett Cannon83e81842008-08-09 23:30:55 +00002432- Copied the implementation of reduce() to _functools.reduce() to have a
2433 version that did not raise a DeprecationWarning under -3.
2434
Antoine Pitrou76b8bee2008-08-09 17:27:23 +00002435- Issue #3205: When iterating over a BZ2File fails allocating memory, raise
2436 a MemoryError rather than silently stop the iteration.
2437
Guido van Rossum59ce9012008-08-09 14:55:34 +00002438- Issue #3487: sre "bytecode" validator. Passing invalid "re-bytecode"
2439 to _sre.compile() will now be rejected. This should not affect anybody
2440 since the re.compile() function never generates invalid re-bytecode.
2441
Skip Montanaroa032bf42008-08-08 22:52:51 +00002442- Issue #3436: Make csv.DictReader's fieldnames attribute a property so that
2443 upon first access it can be automatically initialized from the csv file if
2444 it wasn't initialized during instantiation.
2445
Brett Cannon3aa2a492008-08-06 22:28:09 +00002446- Issue #2338: Create imp.reload() to help with transitioning to Python 3.0 as
2447 the reload() built-in has been removed.
2448
Brett Cannon7e30b672008-08-04 21:52:25 +00002449- Changed code in the following modules/packages to remove warnings raised
Brett Cannonc1b76e42008-08-09 23:06:16 +00002450 while running under the ``-3`` flag: aifc, asynchat, asyncore, bdb, bsddb,

2454 subprocess, sqlite3, tarfile, Tkinter, test.test_support, textwrap,
2455 threading, tokenize, traceback, urlparse, wsgiref, xml, xmlrpclib.

2458 raised an AttributeError.
2459
Benjamin Peterson01a24322008-07-28 23:35:27 +00002460- Issue #2523: Fix quadratic behaviour when read()ing a binary file without
Antoine Pitroude781a42008-08-09 12:43:23 +00002461 asking for a specific length. This problem only affected files opened
2462 using the new "io" module, not the built-in open() function.
Benjamin Peterson01a24322008-07-28 23:35:27 +00002463
Mark Dickinsonfe84cce2008-07-27 06:39:07 +00002464- Issue #3449: Update decimal module to use most recent specification
2465 (v. 1.68) and tests (v. 2.58) from IBM.
2466

2475
2476- Issue #3303: Fix a crash in locale.strcoll() when calling it with
2477 invalid arguments.
2478
2479- Issue #3302: Fix several crashes when calling locale's gettext functions
2480 with None arguments.

2486
Antoine Pitrou5fdfa3e2008-07-25 19:42:26 +00002487- Issue #3394: zipfile.writestr sets external attributes when passed a
2488 file name rather than a ZipInfo instance, so files are extracted with
2489 mode 0600 rather than 000 under Unix.
2490
Gregory P. Smitha36f8fe2008-08-04 00:13:29 +00002491- Issue #1857: subprocess.Popen.poll gained an additional _deadstate keyword
2492 argument in python 2.5, this broke code that subclassed Popen to include its
2493 own poll method. Fixed my moving _deadstate to an _internal_poll method.

2502
Nick Coghlan6e8fef02008-08-18 13:14:22 +00002503- Issue #2235: the C API function PyObject_HashNotImplemented and its
2504 interaction with the tp_hash slot (added in 2.6b2) are now documented
2505
Nick Coghlan2a0c2b12008-08-04 12:47:17 +00002506- Issue #643841: The language reference now provides more detailed
2507 coverage of the lookup process for special methods. The disclaimers
2508 regarding lack of coverage of new-style classes have also been
2509 removed, since the coverage is now fairly reasonable.

Raymond Hettingere3ae6552008-06-20 04:18:15 +00002512What's New in Python 2.6 beta 2?
2513================================
2514
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00002515*Release date: 17-Jul-2008*
2516
Raymond Hettingere3ae6552008-06-20 04:18:15 +00002517Core and Builtins
2518-----------------
2519
Georg Brandl3e483f62008-07-16 22:57:41 +00002520- Issue #3156: Fix inconsistent behavior of the bytearray type: all
2521 its methods now allow for items objects that can be converted to
2522 an integer using operator.index().
2523
Mark Dickinson64b7e502008-07-16 09:40:03 +00002524- Issue #3360: Fix incorrect parsing of '020000000000.0', which
2525 produced a ValueError instead of giving the correct float.
2526
Eric Smitha5fa5a22008-07-16 00:11:49 +00002527- Issue #3083: Add alternate (#) formatting for bin, oct, hex output
2528 for str.format(). This adds the prefix 0b, 0o, or 0x, respectively.
2529
Mark Dickinson7103aa42008-07-15 19:08:33 +00002530- Issue #3008: the float type has a new instance method 'float.hex'
2531 and a new class method 'float.fromhex' to convert floating-point
2532 numbers to and from hexadecimal strings, respectively.
2533
Nick Coghlan6d6bd442008-07-15 15:40:22 +00002534- Issue #2235: __hash__ is once again inherited by default. To allow
2535 collections.Hashable to remain meaningful in the presence of the
2536 default hash implementation (object.__hash__), it is now possible
2537 to explicit block inheritance of hash by setting __hash__=None at
2538 the Python level, or tp_hash=PyObject_HashNotImplemented at the C
2539 level.
2540
Nick Coghlanb028f502008-07-13 14:52:36 +00002541- Issue #3221: Issue a RuntimeWarning instead of raising SystemError if
2542 the parent module cannot be found while performing an absolute import.
2543 This means that an incorrectly defined __package__ attribute will
2544 now only prevent relative imports in that module rather than causing
2545 all imports from that module to fail.
2546
Nick Coghlan14ff9942008-07-08 14:21:42 +00002547- Issue #2517: Allow unicode messages in Exceptions again by correctly
2548 bypassing the instance dictionary when looking up __unicode__ on
2549 new-style classes.
2550
Amaury Forgeot d'Arcbdd941f2008-07-01 20:38:04 +00002551- Issue #3242: Fix a crash inside the print statement, if sys.stdout is
2552 set to a custom object whose write() method happens to install
2553 another file in sys.stdout.
2554
Amaury Forgeot d'Arc1f40c8a2008-06-30 22:42:40 +00002555- Issue #3088: Corrected a race condition in classes derived from

2557 another thread's dictionary.
2558
Mark Dickinson1ec2fcd2008-06-20 14:53:43 +00002559- Issue #3004: Minor change to slice.indices(): the start and stop
2560 arguments are now treated identically, making the behaviour easier
2561 to describe and understand. For example, slice(None, -10,
2562 1).indices(9) now returns (0, 0, 1) instead of (0, -1, 1), and
2563 slice(None, 10, -1).indices(10) returns (9, 9, -1) instead of (9,
2564 10, -1).

Georg Brandl5cc774e2008-06-11 20:28:06 +00003018 PPC64 and x86_64 support in one binary).
Ronald Oussoren5640ce22008-06-05 12:58:24 +00003019
3020 This is controlled by the configure argument ``--with-universal-archs``:

Georg Brandl3ee81df2008-05-17 18:14:43 +00003080- Issue #1631171: Re-implement the 'warnings' module in C (the
3081 original Python code has been kept as backup). This will allow for
3082 using the 'warning's machinery in such places as the parser where
3083 use of pure Python code is not possible. Both the ``showarning()``
3084 and ``formatwarning()`` gain an optional 'line' argument which is
3085 not called by default for backwards-compatibility reasons. Setting
3086 ``warnings.showwarning()`` to an implementation that lacks support
3087 for the ``line`` argument will raise a DeprecationWarning.

Georg Brandl3ee81df2008-05-17 18:14:43 +00003150- Issue #2550: The approach used by client/server code for obtaining
3151 ports to listen on in network-oriented tests has been refined in an
3152 effort to facilitate running multiple instances of the entire
3153 regression test suite in parallel without issue.
3154 test_support.bind_port() has been fixed such that it will always
3155 return a unique port -- which wasn't always the case with the
3156 previous implementation, especially if socket options had been set
3157 that affected address reuse (i.e. SO_REUSEADDR, SO_REUSEPORT). The
3158 new implementation of bind_port() will actually raise an exception
3159 if it is passed an AF_INET/SOCK_STREAM socket with either the
3160 SO_REUSEADDR or SO_REUSEPORT socket option set. Furthermore, if
3161 available, bind_port() will set the SO_EXCLUSIVEADDRUSE option on
3162 the socket it's been passed. This currently only applies to
3163 Windows. This option prevents any other sockets from binding to the
3164 host/port we've bound to, thus removing the possibility of the
3165 'non-deterministic' behaviour, as Microsoft puts it, that occurs
3166 when a second SOCK_STREAM socket binds and accepts to a host/port
3167 that's already been bound by another socket. The optional preferred
3168 port parameter to bind_port() has been removed. Under no
3169 circumstances should tests be hard coding ports!
3170
3171 test_support.find_unused_port() has also been introduced, which will
3172 pass a temporary socket object to bind_port() in order to obtain an
3173 unused port. The temporary socket object is then closed and
3174 deleted, and the port is returned. This method should only be used
3175 for obtaining an unused port in order to pass to an external program
3176 (i.e. the -accept [port] argument to openssl's s_server mode) or as
3177 a parameter to a server-oriented class that doesn't give you direct
3178 access to the underlying socket used.
3179
3180 Finally, test_support.HOST has been introduced, which should be used
3181 for the host argument of any relevant socket calls (i.e. bind and
3182 connect).
Trent Nelsone41b0062008-04-08 23:47:30 +00003183
3184 The following tests were updated to following the new conventions:
Georg Brandl3ee81df2008-05-17 18:14:43 +00003185 test_socket, test_smtplib, test_asyncore, test_ssl, test_httplib,
Trent Nelsone41b0062008-04-08 23:47:30 +00003186 test_poplib, test_ftplib, test_telnetlib, test_socketserver,
3187 test_asynchat and test_socket_ssl.
3188
Georg Brandl3ee81df2008-05-17 18:14:43 +00003189 It is now possible for multiple instances of the regression test
3190 suite to run in parallel without issue.

3458
Fred Drakea8ee94b2008-03-01 02:45:07 +00003459- Issue #2051: pyc and pyo files are no longer created with permission
Barry Warsaw52973612008-03-01 02:23:38 +00003460 644. The mode is now inherited from the py file.

3463
3464- Patch #1759: Backport of PEP 3129 class decorators.
Christian Heimes5224d282008-02-23 15:01:05 +00003465
Vinay Sajipb7edfc42008-04-02 21:10:23 +00003466- Issue #1881: An internal parser limit has been increased. Also see
Facundo Batistafc2d0102008-02-23 12:01:13 +00003467 issue 215555 for a discussion.
3468
Eric Smitha73fbe72008-02-23 03:09:44 +00003469- Added the future_builtins module, which contains hex() and oct().
3470 These are the PEP 3127 version of these functions, designed to be
3471 compatible with the hex() and oct() builtins from Python 3.0. They
3472 differ slightly in their output formats from the existing, unchanged
3473 Python 2.6 builtins. The expected usage of the future_builtins
3474 module is:
3475 from future_builtins import hex, oct
3476
Eric Smith7ef40bf2008-02-20 23:34:22 +00003477- Issue #1600: Modifed PyOS_ascii_formatd to use at most 2 digit
3478 exponents for exponents with absolute value < 100. Follows C99
3479 standard. This is a change on Windows, which would use 3 digits.
3480 Also, added 'n' to the formats that PyOS_ascii_formatd understands,
3481 so that any alterations it does to the resulting string will be
3482 available in stringlib/formatter.h (for float.__format__).
3483
Eric Smith5a3c1352008-02-19 13:21:56 +00003484- Implemented PEP 3101, Advanced String Formatting. This adds a new
3485 builtin format(); a format() method for str and unicode; a
3486 __format__() method to object, str, unicode, int, long, float, and
3487 datetime; the class string.Formatter; and the C API
3488 PyObject_Format().
3489
Georg Brandl3ee81df2008-05-17 18:14:43 +00003490- Fixed several potential crashes, all caused by specially crafted
3491 __del__ methods exploiting objects in temporarily inconsistent
3492 state.
Amaury Forgeot d'Arc632fad32008-02-16 20:55:24 +00003493
Vinay Sajipb7edfc42008-04-02 21:10:23 +00003494- Issue #2115: Important speedup in setting __slot__ attributes. Also
Georg Brandl3ee81df2008-05-17 18:14:43 +00003495 prevent a possible crash: an Abstract Base Class would try to access
3496 a slot on a registered virtual subclass.
Amaury Forgeot d'Arc60d6c7f2008-02-15 21:22:45 +00003497

Georg Brandl3ee81df2008-05-17 18:14:43 +00003501- Clear all free lists during a gc.collect() of the highest generation
3502 in order to allow pymalloc to free more arenas. Python may give back
3503 memory to the OS earlier.
Christian Heimes3b718a72008-02-14 12:47:33 +00003504
Georg Brandl3ee81df2008-05-17 18:14:43 +00003505- Issue #2045: Fix an infinite recursion triggered when printing a
3506 subclass of collections.defaultdict, if its default_factory is set
3507 to a bound method.
Amaury Forgeot d'Arcb01aa432008-02-08 00:56:02 +00003508
Christian Heimesf75dbef2008-02-08 00:11:31 +00003509- Fixed a minor memory leak in dictobject.c. The content of the free
3510 list was not freed on interpreter shutdown.
3511
Georg Brandl3ee81df2008-05-17 18:14:43 +00003512- Limit free list of method and builtin function objects to 256
3513 entries each.
Christian Heimes6075a822008-02-06 12:44:34 +00003514
Georg Brandl3ee81df2008-05-17 18:14:43 +00003515- Patch #1953: Added ``sys._compact_freelists()`` and the C API
3516 functions ``PyInt_CompactFreeList`` and ``PyFloat_CompactFreeList``
Christian Heimes422051a2008-02-04 18:00:12 +00003517 to compact the internal free lists of pre-allocted ints and floats.
3518
Georg Brandl3ee81df2008-05-17 18:14:43 +00003519- Issue #1983: Fixed return type of fork(), fork1() and forkpty()
3520 calls. Python expected the return type int but the fork familie
3521 returns pi_t.
Christian Heimes951cc0f2008-01-31 23:08:23 +00003522
Georg Brandl3ee81df2008-05-17 18:14:43 +00003523- Issue #1678380: Fix a bug that identifies 0j and -0j when they
3524 appear in the same code unit.
Mark Dickinson105be772008-01-31 22:17:37 +00003525
Georg Brandl3ee81df2008-05-17 18:14:43 +00003526- Issue #2025: Add tuple.count() and tuple.index() methods to comply
3527 with the collections.Sequence API.

Georg Brandl3ee81df2008-05-17 18:14:43 +00003532- Added ``PyType_ClearCache()`` and ``sys._clear_type_cache`` to clear
3533 the internal lookup cache for ref leak tests.
Christian Heimes908caac2008-01-27 23:34:59 +00003534
Georg Brandl3ee81df2008-05-17 18:14:43 +00003535- Patch #1473257: generator objects gain a gi_code attribute. This is
3536 the same object as the func_code attribute of the function that
3537 produced the generator.
Georg Brandl0cdf9a32008-01-26 14:14:20 +00003538
Georg Brandl3ee81df2008-05-17 18:14:43 +00003539- Issue #1920: "while 0" statements were completely removed by the
3540 compiler, even in the presence of an "else" clause, which is
3541 supposed to be run when the condition is false. Now the compiler
3542 correctly emits bytecode for the "else" suite.
Amaury Forgeot d'Arc31eaafe2008-01-24 22:59:25 +00003543
Guido van Rossumeead05f2008-01-24 18:21:02 +00003544- A few crashers fixed: weakref_in_del.py (issue #1377858);
3545 loosing_dict_ref.py (issue #1303614, test67.py);
3546 borrowed_ref_[34].py (not in tracker).
3547
Vinay Sajipd7cf32e2008-01-24 12:43:33 +00003548- Issue #1069410: The "can't load dll" message box on Windows is
Christian Heimesb2302ba2008-01-23 17:15:06 +00003549 suppressed while an extension is loaded by calling SetErrorMode in
3550 dynload_win.c. The error is still reported properly.
3551
Georg Brandl3ee81df2008-05-17 18:14:43 +00003552- Issue #1915: Python compiles with --enable-unicode=no again. However
Christian Heimes082c9b02008-01-23 14:20:50 +00003553 several extension methods and modules do not work without unicode
3554 support.
3555
Georg Brandl26543b12008-01-21 18:36:51 +00003556- Issue #1882: when compiling code from a string, encoding cookies in the
3557 second line of code were not always recognized correctly.
3558
Georg Brandl14404b62008-01-19 19:27:05 +00003559- Issue #1679: "0x" was taken as a valid integer literal.
3560
Georg Brandl6caad7d2008-01-26 14:19:22 +00003561- Issue #1865: ``bytes`` as an alias for ``str`` and b"" as an alias "" were
Christian Heimes288e89a2008-01-18 18:24:07 +00003562 added.
3563
Christian Heimesc94e2b52008-01-14 04:13:37 +00003564- sys.float_info / PyFloat_GetInfo: The floating point information
3565 object was converted from a dict to a specialized structseq object.
3566
Georg Brandl3ee81df2008-05-17 18:14:43 +00003567- Patch #1816: Added sys.flags structseq. It exposes the status of
3568 most command line arguments and PYTHON* environment variables.
Christian Heimesf31b69f2008-01-14 03:42:48 +00003569
Georg Brandl3ee81df2008-05-17 18:14:43 +00003570- Objects/structseq.c: Implemented new structseq representation. The
3571 patch makes structseqs (e.g. the return value of os.stat) more
3572 readable.
Christian Heimes9c201962008-01-14 03:33:52 +00003573
Georg Brandl3ee81df2008-05-17 18:14:43 +00003574- Patch #1700288: added a type attribute cache that caches method

3583 envvar and sys.dont_write_bytecode attribute. All these can be set
3584 to forbid Python to attempt to write compiled bytecode files.
Georg Brandl2da0fce2008-01-07 17:09:35 +00003585
Georg Brandl3ee81df2008-05-17 18:14:43 +00003586- Improve some exception messages when Windows fails to load an
3587 extension module. Now we get for example '%1 is not a valid Win32
3588 application' instead of 'error code 193'.
Amaury Forgeot d'Arce0b76952008-01-04 02:04:15 +00003589

Christian Heimes0a8143f2007-12-18 23:22:54 +00003595- Issue #1635: Platform independent creation and representation of NaN
Georg Brandl3ee81df2008-05-17 18:14:43 +00003596 and INF. float("nan"), float("inf") and float("-inf") now work on
3597 every platform with IEEE 754 semantics.
Christian Heimes0a8143f2007-12-18 23:22:54 +00003598
Georg Brandl3ee81df2008-05-17 18:14:43 +00003599- Compiler now generates simpler and faster code for dictionary
3600 literals. The oparg for BUILD_MAP now indicates an estimated
3601 dictionary size. There is a new opcode, STORE_MAP, for adding
3602 entries to the dictionary.

3627
Georg Brandl3ee81df2008-05-17 18:14:43 +00003628- Issue #1460: The utf-7 incremental decoder did not accept truncated
3629 input. It now correctly saves its state between chunks of data.
Amaury Forgeot d'Arcf57375a2007-11-21 01:38:26 +00003630
Georg Brandl3ee81df2008-05-17 18:14:43 +00003631- Patch #1739468: Directories and zipfiles containing a __main__.py
3632 file can now be directly executed by passing their name to the
3633 interpreter. The directory/zipfile is automatically inserted as the
3634 first entry in sys.path.
Nick Coghlan327a39b2007-11-18 11:56:28 +00003635
Georg Brandl3ee81df2008-05-17 18:14:43 +00003636- Issue #1265: Fix a problem with sys.settrace, if the tracing
3637 function uses a generator expression when at the same time the
3638 executed code is closing a paused generator.
Amaury Forgeot d'Arc0d75f092007-11-13 21:54:28 +00003639
Raymond Hettinger1760c8a2007-11-08 02:52:43 +00003640- sets and frozensets now have an isdisjoint() method.
3641

3643
Neal Norwitz44f326e2007-10-05 05:29:17 +00003644- Fix warnings found by the new version of the Coverity checker.
3645
Georg Brandl3ee81df2008-05-17 18:14:43 +00003646- The enumerate() builtin function is no longer bounded to sequences
3647 smaller than LONG_MAX. Formerly, it raised an OverflowError. Now,
3648 automatically shifts from ints to longs.
Raymond Hettinger8f669372007-10-03 21:18:11 +00003649
Georg Brandl3ee81df2008-05-17 18:14:43 +00003650- Issue #1686386: Tuple's tp_repr did not take into account the
3651 possibility of having a self-referential tuple, which is possible
3652 from C code. Nor did object's tp_str consider that a type's tp_str
3653 could do something that could lead to an inifinite recursion.
3654 Py_ReprEnter() and Py_EnterRecursiveCall(), respectively, fixed the
3655 issues.
Brett Cannon0b14f242007-09-30 19:45:10 +00003656
Georg Brandl3ee81df2008-05-17 18:14:43 +00003657- Issue #1164: It was possible to trigger deadlock when using the
3658 'print' statement to write to a file since the GIL was not released
3659 as needed. Now PyObject_Print() does the right thing along with
3660 various tp_print implementations of the built-in types and those in
3661 the collections module.
Brett Cannon01531592007-09-17 03:28:34 +00003662
Georg Brandl3ee81df2008-05-17 18:14:43 +00003663- Issue #1147: Exceptions were directly allowing string exceptions in
3664 their throw() method even though string exceptions no longer
3665 allowed.
Brett Cannon4c20bc42007-09-11 21:02:28 +00003666
Georg Brandl3ee81df2008-05-17 18:14:43 +00003667- Issue #1096: Prevent a segfault from getting the repr of a very
3668 deeply nested list by using the recursion counter.
Brett Cannona0c05512007-09-10 21:38:27 +00003669
Brett Cannon1e534b52007-09-07 04:18:30 +00003670- Issue #1202533: Fix infinite recursion calls triggered by calls to
Georg Brandl3ee81df2008-05-17 18:14:43 +00003671 PyObject_Call() never calling back out to Python code to trigger
3672 recursion depth updates/checks. Required the creation of a static
3673 RuntimeError instance in case normalizing an exception put the
3674 recursion check value past its limit. Fixes crashers
3675 infinite_rec_(1|2|4|5).py.
Brett Cannon1e534b52007-09-07 04:18:30 +00003676

Neal Norwitz0ac60192007-05-27 04:08:54 +00003690- Add new attribute names for function objects. All the func_* become
Georg Brandl3ee81df2008-05-17 18:14:43 +00003691 __*__ attributes. (Some already existed, e.g., __doc__ and
3692 __name__.)
Neal Norwitz0ac60192007-05-27 04:08:54 +00003693
Neal Norwitz8b2bfbc2007-05-23 06:35:32 +00003694- Add -3 option to the interpreter to warn about features that are
3695 deprecated and will be changed/removed in Python 3.0.
3696
Georg Brandl2134e752007-05-21 20:34:16 +00003697- Patch #1686487: you can now pass any mapping after '**' in function
3698 calls.
3699
Collin Winter62903052007-05-18 23:11:24 +00003700- except clauses may now be spelled either "except E, target:" or
Georg Brandl3ee81df2008-05-17 18:14:43 +00003701 "except E as target:". This is to provide forwards compatibility
3702 with Python 3.0.
Collin Winter62903052007-05-18 23:11:24 +00003703
Brett Cannon229cee22007-05-05 01:34:02 +00003704- Deprecate BaseException.message as per PEP 352.
3705
Georg Brandl3ee81df2008-05-17 18:14:43 +00003706- Issue #1303614: don't expose object's __dict__ when the dict is
Armin Rigo9790a272007-05-02 19:23:31 +00003707 inherited from a builtin base.
3708
Vinay Sajip8549ce32007-05-06 17:53:37 +00003709- When __slots__ are set to a unicode string, make it work the same as
Neal Norwitzcbd9ee62007-04-14 05:25:50 +00003710 setting a plain string, ie don't expand to single letter identifiers.
3711
Raymond Hettinger13936692007-04-11 18:40:58 +00003712- Request #1191699: Slices can now be pickled.
3713
Raymond Hettinger4db5fe92007-04-12 04:10:00 +00003714- Request #1193128: str.translate() now allows a None argument for
3715 translations that only remove characters without re-mapping the
3716 remaining characters.
3717
Georg Brandl5cb76c12007-03-21 09:00:39 +00003718- Patch #1682205: a TypeError while unpacking an iterable is no longer
3719 masked by a generic one with the message "unpack non-sequence".
3720
Neal Norwitzaa754b72007-03-21 06:39:48 +00003721- Remove unused file Python/fmod.c.
3722
Guido van Rossum143b5642007-03-23 04:58:42 +00003723- Bug #1683368: The object.__init__() and object.__new__() methods are
3724 now stricter in rejecting excess arguments. The only time when
3725 either allows excess arguments is when it is not overridden and the
3726 other one is. For backwards compatibility, when both are
3727 overridden, it is a deprecation warning (for now; maybe a Py3k
Guido van Rossum234b1ff2007-03-23 19:39:01 +00003728 warning later). Also, type.__init__() insists on the same signature
3729 as supported by type.__new__().
Guido van Rossum143b5642007-03-23 04:58:42 +00003730
Georg Brandl3ee81df2008-05-17 18:14:43 +00003731- Patch #1675423: PyComplex_AsCComplex() now tries to convert an
3732 object to complex using its __complex__() method before falling back
3733 to the __float__() method. Therefore, the functions in the cmath
3734 module now can operate on objects that define a __complex__()
3735 method.
Georg Brandl2b869942007-03-17 16:08:45 +00003736
Georg Brandl3ee81df2008-05-17 18:14:43 +00003737- Patch #1623563: allow __class__ assignment for classes with
3738 __slots__. The old and the new class are still required to have the
3739 same slot names.
Žiga Seilnacht6f2d09c2007-03-16 11:59:38 +00003740
Georg Brandl3ee81df2008-05-17 18:14:43 +00003741- Patch #1642547: Fix an error/crash when encountering syntax errors

Georg Brandl3ee81df2008-05-17 18:14:43 +00003744- Patch #1462488: Python no longer segfaults when
3745 ``object.__reduce_ex__()`` is called with an object that is faking
3746 its type.
Žiga Seilnacht20f43d32007-03-15 11:44:55 +00003747
Georg Brandl3ee81df2008-05-17 18:14:43 +00003748- Patch #1680015: Don't modify __slots__ tuple if it contains an

3752
Georg Brandl7b9c5552007-03-12 14:30:05 +00003753- Bug #1678647: write a newline after printing an exception in any
3754 case, even when converting the value to a string failed.
3755
Georg Brandl871f1bc2007-03-12 13:17:36 +00003756- The dir() function has been extended to call the __dir__() method on
Georg Brandl3ee81df2008-05-17 18:14:43 +00003757 its argument, if it exists. If not, it will work like before. This
3758 allows customizing the output of dir() in the presence of a
3759 __getattr__().
Georg Brandl871f1bc2007-03-12 13:17:36 +00003760
Collin Winter276887b2007-03-12 16:11:39 +00003761- Patch #922167: Python no longer segfaults when faced with infinitely
3762 self-recursive reload() calls (as reported by bug #742342).
3763
Georg Brandl3ee81df2008-05-17 18:14:43 +00003764- Patch #1675981: remove unreachable code from ``type.__new__()``
3765 method.

Georg Brandl3ee81df2008-05-17 18:14:43 +00003767- Patch #1491866: change the complex() constructor to allow
3768 parthensized forms. This means complex(repr(x)) now works instead of
3769 raising a ValueError.
Collin Wintere38051d2007-03-09 20:33:07 +00003770
Georg Brandlaa2321b2007-03-07 00:40:28 +00003771- Patch #703779: unset __file__ in __main__ after running a file. This
Georg Brandl3ee81df2008-05-17 18:14:43 +00003772 makes the filenames the warning module prints much more sensible
3773 when a PYTHONSTARTUP file is used.
Georg Brandlaa2321b2007-03-07 00:40:28 +00003774
Georg Brandl49aafc92007-03-07 00:34:46 +00003775- Variant of patch #697613: don't exit the interpreter on a SystemExit
3776 exception if the -i command line option or PYTHONINSPECT environment
Georg Brandl3ee81df2008-05-17 18:14:43 +00003777 variable is given, but break into the interactive interpreter just
3778 like on other exceptions or normal program exit.

3784 condition.
Georg Brandl098cd692007-03-06 12:17:50 +00003785
Georg Brandl0fca97a2007-03-05 22:28:08 +00003786- Patch #1674228: when assigning a slice (old-style), check for the
3787 sq_ass_slice instead of the sq_slice slot.
3788
Georg Brandl3ee81df2008-05-17 18:14:43 +00003789- When printing an unraisable error, don't print exceptions. before
3790 the name. This duplicates the behavior whening normally printing
3791 exceptions.
Neal Norwitz88516a62007-02-26 22:41:45 +00003792
Georg Brandl3ee81df2008-05-17 18:14:43 +00003793- Bug #1653736: Properly discard third argument to

Georg Brandl3ee81df2008-05-17 18:14:43 +00003799- Bug #1377858: Fix the segfaulting of the interpreter when an object
3800 created a weakref on itself during a __del__ call for new-style
3801 classes (classic classes still have the bug).

3848
Armin Rigo7ccbca92006-10-04 12:17:45 +00003849- A number of places, including integer negation and absolute value,
3850 were fixed to not rely on undefined behaviour of the C compiler
3851 anymore.

4357
Georg Brandl92a6bae2007-03-13 17:43:32 +00004358- Patch #1603688: ConfigParser.SafeConfigParser now checks values that
Georg Brandl3ee81df2008-05-17 18:14:43 +00004359 are set for invalid interpolation sequences that would lead to

4416 TestCase and TestSuite subclasses (not instances) are no longer
4417 accepted in TestSuite.addTest(). This should cause no
4418 incompatibility since it never made sense with ordinary subclasses
4419 -- the failure just occurred later, with a more cumbersome
4420 exception.

Georg Brandl3ee81df2008-05-17 18:14:43 +00004701- Issue #829951: In the smtplib module, SMTP.starttls() now complies
4702 with RFC 3207 and forgets any knowledge obtained from the server not
4703 obtained from the TLS negotiation itself. Patch contributed by Bill
4704 Fenner.
Gregory P. Smith2b3ba582008-01-17 08:03:17 +00004705
Georg Brandl3ee81df2008-05-17 18:14:43 +00004706- Issue #1339: The smtplib.SMTP class has been refactored a bit such
Gregory P. Smithbde4ae42008-01-17 08:35:49 +00004707 that the SMTP.starttls() caller no longer needs to call ehlo()
4708 beforehand. SMTP.starttls() now raises an exception of the server
Georg Brandl3ee81df2008-05-17 18:14:43 +00004709 does not claim to support starttls. Adds the
4710 SMTP.ehlo_or_helo_if_needed() method. Patch contributed by Bill

Georg Brandl3ee81df2008-05-17 18:14:43 +00004765- itertools.chain() now has an alternate constructor,

4791 complex, tuple, list, dict, set, and frozenset. Formerly, it would
4792 silently miscode subclasses of those types. Now, it raises a
4793 ValueError instead.
Raymond Hettinger12e94202007-11-07 01:13:09 +00004794

Georg Brandl3ee81df2008-05-17 18:14:43 +00004809 time so that opening a database previously created with the DB_DUP
4810 or DB_DUPSORT flag set will keep the proper behavior on subsequent
4811 opens. Specifically: dictionary assignment to a DB object will
4812 replace all values for a given key when the database allows
4813 duplicate values. DB users should use DB.put(k, v) when they want
4814 to store duplicates; not DB[k] = v.
Gregory P. Smithec10a4a2007-11-05 02:32:26 +00004815

4821 characters with ASCII value less than 32. Also, it correctly quotes
4822 dots only if they occur on a single line, as opposed to the previous
4823 behavior of quoting dots if they are the second character of any
4824 line.
Georg Brandl4aef7272007-03-13 22:49:43 +00004825

5095 default, this option is turned-off. It should only be enabled in
5096 debugged, performance critical applications.

5147-----
5148
Georg Brandl3ee81df2008-05-17 18:14:43 +00005149- Unified naming convention for free lists and their limits. All free
5150 lists in Object/ are named ``free_list``, the counter ``numfree``
5151 and the upper limit is a macro ``PyName_MAXFREELIST`` inside an
5152 #ifndef block.
Christian Heimes5b970ad2008-02-06 13:33:44 +00005153
Georg Brandl3ee81df2008-05-17 18:14:43 +00005154- ``PySet_Add()`` can now modify a newly created frozenset. Similarly
5155 to ``PyTuple_SetItem``, it can be used to populate a brand new
5156 frozenset; but it does not steal a reference to the added item.

5168
Georg Brandl3ee81df2008-05-17 18:14:43 +00005169- Issue #1521: On 64bit platforms, using PyArgs_ParseTuple with the t#
5170 of w# format code incorrectly truncated the length to an int, even
5171 when PY_SSIZE_T_CLEAN is set. The str.decode method used to return
5172 incorrect results with huge strings.
Georg Brandl6caad7d2008-01-26 14:19:22 +00005173
Georg Brandl3ee81df2008-05-17 18:14:43 +00005174- Issue #1629: Renamed Py_Size, Py_Type and Py_Refcnt to Py_SIZE,

5192- Fix some leftovers from the conversion from int to Py_ssize_t
5193 (relevant to strings and sequences of more than 2**31 items).
5194
5195- Make _PyGILState_NoteThreadState() static, it was not used anywhere
5196 outside of pystate.c and should not be necessary.
5197
Georg Brandl3ee81df2008-05-17 18:14:43 +00005198- ``PyImport_Import`` and ``PyImport_ImportModule`` now always do
5199 absolute imports. In earlier versions they might have used relative
5200 imports under some conditions.
Christian Heimes000a0742008-01-03 22:16:32 +00005201
Georg Brandl3ee81df2008-05-17 18:14:43 +00005202- Added case insensitive comparison methods ``PyOS_stricmp(char*,
5203 char*)`` and ``PyOS_strnicmp(char*, char*, Py_ssize_t)``.
Christian Heimes000a0742008-01-03 22:16:32 +00005204
Georg Brandl3ee81df2008-05-17 18:14:43 +00005205- Bug #1542693: remove semi-colon at end of PyImport_ImportModuleEx

5213 requires Windows 2000 or greater. The _WINVER and NTDDI_VERSION
5214 macros are set to Win2k for x86/32bit builds and WinXP for AMD64
5215 builds.
Christian Heimes95d64472008-02-09 19:55:22 +00005216

Georg Brandl3ee81df2008-05-17 18:14:43 +00005230- Removed the macfs module. It had been deprecated since Python 2.5.
5231 This lead to the deprecation of macostools.touched() as it relied
5232 solely on macfs and was a no-op under OS X.
