Antoine Pitroue80a6a42010-01-17 12:26:20 +000015- Issue #7561: Operations on empty bytearrays (such as `int(bytearray())`)
16 could crash in many places because of the PyByteArray_AS_STRING() macro
17 returning NULL. The macro now returns a statically allocated empty
18 string instead.
19
Antoine Pitrou64672132010-01-13 07:55:48 +000020- Issue #7622: Improve the split(), rsplit(), splitlines() and replace()
21 methods of bytes, bytearray and unicode objects by using a common
22 implementation based on stringlib's fast search. Patch by Florent Xicluna.
23
Mark Dickinson476279f2010-01-16 10:44:00 +000024- Issue #7632: Fix various str -> float conversion bugs present in 2.7
25 alpha 2, including: (1) a serious 'wrong output' bug that could
26 occur for long (> 40 digit) input strings, (2) a crash in dtoa.c
27 that occurred in debug builds when parsing certain long numeric
Mark Dickinson23df3d22010-01-17 13:37:57 +000028 strings corresponding to subnormal values, (3) a memory leak for
29 some values large enough to cause overflow, and (4) a number of
30 flaws that could lead to incorrectly rounded results.

Tarek Ziadéf14c7fc2010-01-24 00:33:32 +000045- Issue #7748: Since unicode values are supported for some metadata options
46 in Distutils, the DistributionMetadata get_* methods will now return an utf-8
47 encoded string for them. This ensure that the upload and register commands
48 send the right values to PyPI without any error.
49
R. David Murrayed44dfa2010-01-16 05:15:17 +000050- Issue #1670765: Prevent email.generator.Generator from re-wrapping
51 headers in multipart/signed MIME parts, which fixes one of the sources of
52 invalid modifications to such parts by Generator.
53
Antoine Pitrouc391ad02010-01-15 00:18:00 +000054- Issue #7701: Fix crash in binascii.b2a_uu() in debug mode when given a

Benjamin Peterson4f51baf2009-12-05 18:40:02 +0000103What's New in Python 2.7 alpha 2?
104=================================

Benjamin Petersonaa7e51f2010-01-09 16:34:06 +0000106*Release date: 2010-01-09*
Benjamin Peterson4f51baf2009-12-05 18:40:02 +0000107
108Core and Builtins
109-----------------
110
Benjamin Petersonecdae192010-01-04 00:43:01 +0000111- The __complex__ method is now looked up on the class of instances to make it
112 consistent with other special methods.
113
Antoine Pitrou5b7139a2010-01-02 21:12:58 +0000114- Issue #7462: Implement the stringlib fast search algorithm for the `rfind`,
115 `rindex`, `rsplit` and `rpartition` methods. Patch by Florent Xicluna.
116
Mark Dickinson1b34d252010-01-01 17:27:30 +0000117- Issue #5080: A number of functions and methods previously produced a
118 DeprecationWarning when passed a float argument where an integer was
119 expected. These functions and methods now raise TypeError instead.
120 The majority of the effects of this change are in the extension
121 modules, but some core functions and methods are affected: notably
122 the 'chr', 'range' and 'xrange' builtins, and many unicode/str
123 methods.
124
Benjamin Peterson0f02d392009-12-30 19:34:10 +0000125- Issue #7604: Deleting an unset slotted attribute did not raise an
126 AttributeError.
127
Mark Dickinson99d652e2009-12-30 12:12:23 +0000128- Issue #7534: Fix handling of IEEE specials (infinities, nans,
129 negative zero) in ** operator. The behaviour now conforms to that
130 described in C99 Annex F.
131
Amaury Forgeot d'Arcc8a2ce72009-12-29 23:06:17 +0000132- Issue #7579: the msvcrt module now has docstrings for all its functions.
133
Amaury Forgeot d'Arc8645a5c2009-12-29 22:03:38 +0000134- Issue #7413: Passing '\0' as the separator to datetime.datetime.isoformat()
135 used to drop the time part of the result.
136
Mark Dickinson46572832009-12-27 14:55:57 +0000137- Issue #1811: improve accuracy and cross-platform consistency for
138 true division of integers: the result of a/b is now correctly
139 rounded for ints a and b (at least on IEEE 754 platforms), and in
140 particular does not depend on the internal representation of a long.
141
Ezio Melottif84caf42009-12-24 22:25:17 +0000142- Issue #6108: unicode(exception) and str(exception) should return the same
143 message when only __str__ (and not __unicode__) is overridden in the subclass.
144
Ronald Oussoren92919a62009-12-24 13:30:58 +0000145- Issue #6834: replace the implementation for the 'python' and 'pythonw'
146 executables on OSX.
147
148 These executables now work properly with the arch(1) command:
149 ``arch -ppc python`` will start a universal binary version of python
150 in PPC mode (unlike previous releases).
151
R. David Murray0a0a1a82009-12-14 16:28:26 +0000152- Issue #1680159: unicode coercion during an 'in' operation no longer masks
153 the underlying error when the coercion fails for the left hand operand.
154
Benjamin Peterson4895af42009-12-13 16:36:53 +0000155- Issue #7491: Metaclass's __cmp__ method was ignored.
156
Antoine Pitrou2a08b422009-12-13 16:18:14 +0000157- Issue #7466: segmentation fault when the garbage collector is called
Antoine Pitrou54584182010-01-07 17:54:10 +0000158 in the middle of populating a tuple. Patch by Florent Xicluna.

166 by Arfrever.
167
Antoine Pitrou80157252010-01-08 19:20:17 +0000168- Issue #7092: Remove py3k warning when importing cPickle. 2to3 handles
169 renaming of `cPickle` to `pickle`. The warning was annoying since there's
170 no alternative to cPickle if you care about performance. Patch by Florent
171 Xicluna.
172
Antoine Pitrou0d423b82010-01-07 17:46:49 +0000173- Issue #7455: Fix possible crash in cPickle on invalid input. Patch by

180 and make it implement the `io.BufferedIOBase` ABC to allow for further
181 speedups by wrapping it in an `io.BufferedReader`. Patch by Nir Aides.
182
183- Issue #3972: httplib.HTTPConnection now accepts an optional source_address
Gregory P. Smith9d325212010-01-03 02:06:07 +0000184 parameter to allow specifying where your connections come from.
185

189 Initial patch by Brian Curtin.
190
Ronald Oussorenca8e7ec2009-12-24 14:50:35 +0000191- Distutils now correctly identifies the build architecture as "x86_64"
Ezio Melotti569e61f2009-12-30 06:14:51 +0000192 when building on OSX 10.6 without "-arch" flags.
Ronald Oussorenca8e7ec2009-12-24 14:50:35 +0000193
Tarek Ziadéf14c7fc2010-01-24 00:33:32 +0000194- Issue #7556: Distutils' msvc9compiler now opens the MSVC Manifest

196
Tarek Ziadé2421d562009-12-20 23:23:34 +0000197- Issue #7552: Removed line feed in the base64 Authorization header in
198 the Distutils upload command to avoid an error when PyPI reads it.
199 This occurs on long passwords. Initial patch by JP St. Pierre.
200
201- Issue #7231: urllib2 cannot handle https with proxy requiring auth.
Senthil Kumaran7713acf2009-12-20 06:05:13 +0000202 Patch by Tatsuhiro Tsujikawa.
203
Benjamin Petersonddd392c2009-12-13 19:19:07 +0000204- Issue #7349: Make methods of file objects in the io module accept None as an
205 argument where file-like objects (ie StringIO and BytesIO) accept them to mean
206 the same as passing no argument.
207
Benjamin Petersonc4771d22009-12-13 17:31:31 +0000208- Issue #7348: StringIO.StringIO.readline(-1) now acts as if it got no argument
209 like other file objects.
210
Lars Gustäbel92ca7562009-12-13 11:32:27 +0000211- Issue #7357: tarfile no longer suppresses fatal extraction errors by

229 PyArg_ParseTupleAndKeywords, PyArg_VaParse,
230 PyArg_VaParseTupleAndKeywords and PyArg_Parse no longer accept float
231 arguments for integer format codes (other than 'L'): previously an
232 attempt to pass a float resulted in a DeprecationWarning; now it
233 gives a TypeError. For the 'L' format code (which previously had no
234 warning) there is now a DeprecationWarning.

278
Amaury Forgeot d'Arcd7288712009-12-01 21:51:04 +0000279- Issue #7419: setlocale() could crash the interpreter on Windows when called
280 with invalid values.
281
Eric Smithc4ab8332009-11-29 17:40:57 +0000282- Issue #3382: 'F' formatting for float and complex now convert the
283 result to upper case. This only affects 'inf' and 'nan', since 'f'
284 no longer converts to 'g' for large values.
Amaury Forgeot d'Arcd7288712009-12-01 21:51:04 +0000285
Mark Dickinson9dd5e162009-11-23 20:54:09 +0000286- Remove switch from "%f" formatting to "%g" formatting for floats
287 larger than 1e50 in absolute value.
288
Mark Dickinson18cfada2009-11-23 18:46:41 +0000289- Remove restrictions on precision when formatting floats. E.g.,
290 "%.120g" % 1e-100 used to raise OverflowError, but now gives the
291 requested 120 significant digits instead.
292
Benjamin Peterson89b1a5c2009-11-19 22:58:01 +0000293- Add Py3k warnings for parameter names in parenthesis.
294
Benjamin Peterson48f0a8d2009-11-19 23:19:29 +0000295- Issue #7362: Give a proper error message for def f((x)=3): pass.

298 on MacOSX 10.6.
299
Mark Dickinsonb678de82009-11-19 18:41:49 +0000300- Issue #7117: repr(x) for a float x returns a result based on the
301 shortest decimal string that's guaranteed to round back to x under
302 correct rounding (with round-half-to-even rounding mode).
303 Previously it gave a string based on rounding x to 17 decimal digits.
304 repr(x) for a complex number behaves similarly. On platforms where
305 the correctly-rounded strtod and dtoa code is not supported (see below),
306 repr is unchanged.
307
308- Issue #7117: On almost all platforms: float-to-string and
309 string-to-float conversions within Python are now correctly rounded.
310 Places these conversions occur include: str for floats and complex
311 numbers; the float and complex constructors; old-style and new-style
312 numeric formatting; serialization and deserialization of floats and
313 complex numbers using marshal, pickle and json; parsing of float and
314 imaginary literals in Python code; Decimal-to-float conversion.
315
316 The conversions use a Python-adapted version of David Gay's
317 well-known dtoa.c, providing correctly-rounded strtod and dtoa C
318 functions. This code is supported on Windows, and on Unix-like
319 platforms using gcc, icc or suncc as the C compiler. There may be a
320 small number of platforms on which correct operation of this code
321 cannot be guaranteed, so the code is not used: notably, this applies
322 to platforms where the C double format is not IEEE 754 binary64, and
323 to platforms on x86 hardware where the x87 FPU is set to 64-bit
324 precision and Python's configure script is unable to determine how
325 to change the FPU precision. On these platforms conversions use the
326 platform strtod and dtoa, as before.

Mark Dickinsonbd15a062009-11-18 19:33:35 +0000328- Issue #7117: Backport round implementation from Python 3.x. round
Mark Dickinsonb678de82009-11-19 18:41:49 +0000329 now uses the correctly-rounded string <-> float conversions
330 described above (when available), and so produces correctly rounded
331 results that will display nicely under the float repr. There are
332 two related small changes: (1) round now accepts any class with an
333 __index__ method for its second argument (but no longer accepts
Mark Dickinsonbd15a062009-11-18 19:33:35 +0000334 floats for the second argument), and (2) an excessively large second
335 integer argument (e.g., round(1.234, 10**100)) no longer raises an
336 exception.

Eric Smitha985a3a2009-05-05 18:26:08 +0000484- Issue #5920: For float.__format__, change the behavior with the
485 empty presentation type (that is, not one of 'e', 'f', 'g', or 'n')
486 to be like 'g' but with at least one decimal point and with a
487 default precision of 12. Previously, the behavior the same but with
488 a default precision of 6. This more closely matches str(), and
489 reduces surprises when adding alignment flags to the empty
490 presentation type. This also affects the new complex.__format__ in
491 the same way.

614
Antoine Pitrouc2f02212009-01-13 23:13:52 +0000615- Issue #4935: The overflow checking code in the expandtabs() method common
616 to str, bytes and bytearray could be optimized away by the compiler, letting
617 the interpreter segfault instead of raising an error.
618
Amaury Forgeot d'Arca40d5732009-01-12 23:36:55 +0000619- Issue #3720: Fix a crash when an iterator modifies its class and removes its
620 __next__ method.
621
Martin v. Löwise3422fa2009-01-12 08:11:24 +0000622- Issue #4893: Use NT threading on CE.

625
Antoine Pitrou4c5ecb72009-01-09 21:40:55 +0000626- Issue #4074: Change the criteria for doing a full garbage collection (i.e.
627 collecting the oldest generation) so that allocating lots of objects without
628 destroying them does not show quadratic performance. Based on a proposal by
Benjamin Petersond50a5d52009-07-13 00:03:20 +0000629 Martin von Löwis at
Antoine Pitrou4c5ecb72009-01-09 21:40:55 +0000630 http://mail.python.org/pipermail/python-dev/2008-June/080579.html.

633
Antoine Pitroue96d4ea2009-01-06 18:10:47 +0000634- Issue #1180193: When importing a module from a .pyc (or .pyo) file with
635 an existing .py counterpart, override the co_filename attributes of all
636 code objects if the original filename is obsolete (which can happen if the
637 file has been renamed, moved, or if it is accessed through different paths).
638 Patch by Ziga Seilnacht and Jean-Paul Calderone.
639
Martin v. Löwis5344c992009-01-02 20:32:55 +0000640- Issue #4075: Use OutputDebugStringW in Py_FatalError.
641
Hirokazu Yamamoto99a1b202009-01-01 15:45:39 +0000642- Issue #4797: IOError.filename was not set when _fileio.FileIO failed to open
643 file with `str' filename on Windows.
644
Antoine Pitrouaa687902009-01-01 14:11:22 +0000645- Issue #3680: Reference cycles created through a dict, set or deque iterator
646 did not get collected.
647
Nick Coghlan180e4002008-12-30 01:18:48 +0000648- Issue #4701: PyObject_Hash now implicitly calls PyType_Ready on types
649 where the tp_hash and tp_dict slots are both NULL.
650
Benjamin Peterson7af65562008-12-29 17:56:58 +0000651- Issue #4764: With io.open, IOError.filename is set when trying to open a
652 directory on POSIX systems.
653
Benjamin Petersonfe231b02008-12-29 17:47:42 +0000654- Issue #4764: IOError.filename is set when trying to open a directory on POSIX
655 systems.
656

658 bytearray.translate(). It was always allowed for bytes.translate().
659
Skip Montanarof205c132008-12-23 03:30:15 +0000660- Added test case to ensure attempts to read from a file opened for writing
661 fail.
662
Antoine Pitrou73c0e652008-12-17 22:46:54 +0000663- Issue #2467: gc.DEBUG_STATS reported invalid elapsed times. Also, always
664 print elapsed times, not only when some objects are uncollectable /
665 unreachable. Original patch by Neil Schemenauer.
666

673 context manager returns a value that cannot be converted to a bool.
674
Jeffrey Yasskinffd42cf2008-12-10 07:35:02 +0000675- Issue #4597: Fixed several opcodes that weren't always propagating
676 exceptions.
677
Mark Dickinson826f3fe2008-12-05 21:55:28 +0000678- Issue #4445: Replace "sizeof(PyStringObject)" with
679 "offsetof(PyStringObject, ob_sval) + 1" when allocating memory for
680 str instances. On a typical machine this saves 3 bytes of memory
681 (on average) per string allocation.
682
Amaury Forgeot d'Arcdc619012008-11-22 20:01:18 +0000683- Issue #3996: On Windows, the PyOS_CheckStack function would cause the
684 interpreter to abort ("Fatal Python error: Could not reset the stack!")
685 instead of throwing a MemoryError.
686
Raymond Hettinger7989a4d2008-12-03 15:42:10 +0000687- Issue #3689: The list reversed iterator now supports __length_hint__
688 instead of __len__. Behavior now matches other reversed iterators.
689
Benjamin Petersonc078f922008-11-21 22:27:24 +0000690- Issue #4367: Python would segfault during compiling when the unicodedata
691 module couldn't be imported and \N escapes were present.
692
Vinay Sajip213faca2008-12-03 23:22:58 +0000693- Issue #4233: Changed semantic of ``_fileio.FileIO``'s ``close()``
Amaury Forgeot d'Arc32265652008-11-20 23:34:31 +0000694 method on file objects with closefd=False. The file descriptor is still
695 kept open but the file object behaves like a closed file. The ``FileIO``
696 object also got a new readonly attribute ``closefd``.
697
Benjamin Peterson46cc6d12008-11-19 21:49:09 +0000698- Issue #4348: Some bytearray methods returned that didn't cause any change to
699 the bytearray, returned the same bytearray instead of a copy.
700
Amaury Forgeot d'Arc7cfe7ea2008-11-18 22:19:37 +0000701- Issue #4317: Fixed a crash in the imageop.rgb2rgb8() function.
702
Benjamin Peterson273c2332008-11-17 22:39:09 +0000703- Issue #4230: If ``__getattr__`` is a descriptor, it now functions correctly.
704
Benjamin Peterson6624a9f2008-11-03 15:14:51 +0000705- Issue #4048: The parser module now correctly validates relative imports.
706
Benjamin Petersondcee09d2008-10-31 02:16:05 +0000707- Issue #4225: ``from __future__ import unicode_literals`` didn't work in an
708 exec statement.
709
Amaury Forgeot d'Arc69a9c5b2008-10-30 21:18:34 +0000710- Issue #4176: Fixed a crash when pickling an object which ``__reduce__``
711 method does not return iterators for the 4th and 5th items.
712
Benjamin Petersonbdca9422008-10-26 20:21:13 +0000713- Issue #4209: Enabling unicode_literals and the print_function in the same
714 __future__ import didn't work.
715
Benjamin Peterson399b1fe2008-10-25 02:53:28 +0000716- Using ``nonlocal`` as a variable name will now raise a Py3k SyntaxWarning
Georg Brandl7fb00ad2008-10-25 07:00:52 +0000717 because it is a reserved word in 3.x.
Benjamin Peterson399b1fe2008-10-25 02:53:28 +0000718
Hirokazu Yamamoto10a018c2008-10-09 10:00:30 +0000719- On windows, os.chdir given unicode was not working if GetCurrentDirectoryW
720 returned a path longer than MAX_PATH. (But It's doubtful this code path is
721 really executed because I cannot move to such directory on win2k)
722
Amaury Forgeot d'Arcd78b9dc2008-10-07 20:32:10 +0000723- Issue #4069: When set.remove(element) is used with a set element, the element
724 is temporarily replaced with an equivalent frozenset. But the eventual
725 KeyError would always report the empty frozenset([]) as the missing key. Now
726 it correctly refers to the initial element.
727
Antoine Pitrouae5bece2008-12-06 21:29:24 +0000728- Issue #4509: Various issues surrounding resize of bytearray objects to
729 which there are buffer exports.
730
Benjamin Peterson8d5934b2008-12-27 18:24:11 +0000731- Issue #4748: Lambda generators no longer return a value.

736
Matthias Kloseedb5e1e2009-04-04 14:18:13 +0000737- Issue #3845: In PyRun_SimpleFileExFlags avoid invalid memory access with
738 short file names.
739
Matthias Klose91a3b9e2009-04-05 21:19:13 +0000740- Issue #1113244: Py_XINCREF, Py_DECREF, Py_XDECREF: Add `do { ... } while (0)'
741 to avoid compiler warnings.
Matthias Klose0610e082009-04-05 12:43:08 +0000742
Gregory P. Smith2b3eb372009-04-05 23:48:26 +0000743- Issue #5705: os.setuid() would not accept values > 2**31-1 but pwd.getpwnam()
744 returned them on 64bit platforms.
745
Walter Dörwalded960ac2009-05-03 22:36:33 +0000746- Issue #5108: Handle %s like %S and %R in PyUnicode_FromFormatV(): Call
747 PyUnicode_DecodeUTF8() once, remember the result and output it in a second
748 step. This avoids problems with counting UTF-8 bytes that ignores the effect
749 of using the replace error handler in PyUnicode_DecodeUTF8().
750
Walter Dörwald726ba8e2009-05-06 14:32:35 +0000751- Issue #3739: The unicode-internal encoder now reports the number of characters
752 consumed like any other encoder (instead of the number of bytes).
753
Benjamin Peterson91c12eb2009-12-03 02:52:39 +0000754- Issue #2422: When compiled with the ``--with-valgrind`` option, the
755 pymalloc allocator will be automatically disabled when running under
756 Valgrind. This gives improved memory leak detection when running
757 under Valgrind, while taking advantage of pymalloc at other times.

2138
Amaury Forgeot d'Arc05e34492008-09-10 22:04:45 +00002139- Issue #3743: In a few places, PY_FORMAT_SIZE_T was incorrectly used with
2140 PyString_FromFormat or PyErr_Format to display size_t values. The macro
2141 PY_FORMAT_SIZE_T is designed to select the correct format for the OS
2142 ``printf`` function, whereas PyString_FromFormat has an independent
2143 implementation and uses "%zd" on all platforms for size_t values.
2144 This makes a difference on win64, where ``printf`` needs "%Id" to display
2145 64bit values.

2151 object; previously an int would be returned for small values. the __long__

Antoine Pitroud4ae97b2008-08-29 18:39:48 +00002162 was correctly parsed but parsing of subsequent arguments failed.
2163
Vinay Sajip35e3b032008-09-01 14:33:59 +00002164- Issue #2534: speed up isinstance() and issubclass() by 50-70%, so as to
Antoine Pitrou0668c622008-08-26 22:42:08 +00002165 match Python 2.5 speed despite the __instancecheck__ / __subclasscheck__
2166 mechanism. In the process, fix a bug where isinstance() and issubclass(),
2167 when given a tuple of classes as second argument, were looking up
2168 __instancecheck__ / __subclasscheck__ on the tuple rather than on each
2169 type object.

Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00002308What's New in Python 2.6 beta 3?
2309================================
2310
Barry Warsaw07a4a382008-08-21 01:15:08 +00002311*Release date: 20-Aug-2008*
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00002312
2313Core and Builtins
2314-----------------
2315
Guido van Rossumf8402962008-08-20 15:01:50 +00002316- Issue #1878: Remove Py_TPFLAGS_HAVE_VERSION_TAG from
2317 Py_TPFLAGS_DEFAULT when not building the core. This means 3rd party
2318 extensions do not automatically benefit from the class attribute
2319 cache; they will have to explicitly add Py_TPFLAGS_HAVE_VERSION_TAG
2320 to their tp_flags field if they care. This is a backwards
2321 compatibility feature; in 3.0, all types will use the cache by
2322 default.
2323
Benjamin Petersonf647dc12008-08-20 01:27:30 +00002324- Keyword arguments can now follow starred arguments. (``f(a, *args,
2325 keyword=23)`` is now valid syntax.)
2326
Thomas Heller0ad5ae02008-08-19 19:25:04 +00002327- ctypes function pointers that are COM methods have a boolean True
2328 value again.
2329
Martin v. Löwisf91d46a2008-08-12 14:49:50 +00002330- Issue #3139: Make buffer-interface thread-safe wrt. PyArg_ParseTuple,
2331 by denying s# to parse objects that have a releasebuffer procedure,
2332 and introducing s*.
2333
Georg Brandl1e13ea92008-08-11 09:07:59 +00002334- Issue #3537: Fix an assertion failure when an empty but presized dict
2335 object was stored in the freelist.
2336
Mark Dickinsonb6467572008-08-04 21:30:09 +00002337- Issue #1481296: Make long(float('nan')) and int(float('nan')) raise
2338 ValueError consistently across platforms.
2339
Amaury Forgeot d'Arc39fd6722008-07-31 21:28:03 +00002340- Issue #3479: On platforms where sizeof(int) is smaller than sizeof(long)
2341 (64bit Unix, for example), unichr() would truncate its argument and return
2342 u'\x00' for unichr(2**32). Now it properly raises an OverflowError.
2343
Neal Norwitze7d8be82008-07-31 17:17:14 +00002344- Apply security patches from Apple.
2345
Amaury Forgeot d'Arc246daed2008-07-31 00:42:16 +00002346- Issue #2542: Now that issubclass() may call arbitrary code, ensure that
2347 PyErr_ExceptionMatches returns 0 when an exception occurs there.
2348
Antoine Pitrou92f82162008-07-25 22:22:08 +00002349- Issue #1819: function calls with several named parameters are now on
2350 average 35% faster (as measured by pybench).
2351
Amaury Forgeot d'Arce4921fe2008-07-21 22:00:38 +00002352- Issue #2378: An unexpected UnboundLocalError or NameError could appear when
2353 the python debugger steps into a class statement: the free variables (local
2354 variables defined in an outer scope) would be deleted from the outer scope.
2355
Gregory P. Smith0470bab2008-07-22 04:46:32 +00002356- Issue #2620: Overflow checking when allocating or reallocating memory
2357 was not always being done properly in some python types and extension
2358 modules. PyMem_MALLOC, PyMem_REALLOC, PyMem_NEW and PyMem_RESIZE have
2359 all been updated to perform better checks and places in the code that
2360 would previously leak memory on the error path when such an allocation
2361 failed have been fixed.
2362
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00002363Library
2364-------
2365
Hirokazu Yamamoto838c79f2008-08-20 13:14:07 +00002366- Issue #3612: Added some missing basic types in ctypes.wintypes.
2367
Benjamin Petersone977ad42008-08-20 01:42:01 +00002368- The methods ``is_in_tuple()``, ``is_vararg()``, and ``is_keywordarg()`` of
2369 symtable.Symbol have been deprecated for removal in 3.0 and the next release.
2370
Amaury Forgeot d'Arc351ffb82008-08-18 19:23:47 +00002371- Issue #2234: distutils failed for some versions of the cygwin compiler. The
2372 version reported by these tools does not necessarily follow the python
2373 version numbering scheme, so the module is less strict when parsing it.
2374
Nick Coghlanf70385a2008-08-18 12:42:46 +00002375- Issue #2235: Added Py3k warnings for types which will become unhashable
2376 under the stricter __hash__ inheritance rules in 3.0. Several types
2377 which did not meet the rules for hash invariants and were already
2378 unhashable in 3.0 have now been explicitly flagged as unhashable in
2379 2.6 as well (collections.Mapping, collections.Set, unittest.TestSuite,
2380 xml.dom.minidom.NamedNodeMap, numbers.Number, UserList.UserList)
2381
Brett Cannon88f801d2008-08-18 00:46:22 +00002382- Update __all__ for cookielib, csv, os, urllib2, and weakref to include things
2383 imported into the module but exposed as part of the module's API.
2384
Brett Cannon7b96f072008-08-18 00:41:11 +00002385- Remove an unneeded import of abc.ABCMeta from 'inspect'.
2386
Brett Cannon46225e72008-08-18 00:36:52 +00002387- Remove unneeded imports of 'sys' and 'warnings' from 'io'.
2388
Brett Cannon25c9d6a2008-08-17 22:10:11 +00002389- Remove unneeded imports of 'warnings' from shelve, filecmp, and dummy_thread.
2390
Hirokazu Yamamoto41a81eb2008-08-17 13:10:46 +00002391- Issue #3575: Incremental decoder's decode function now takes bytearray
2392 by using 's*' instead of 't#'.
2393
Mark Dickinson3e4caeb2009-02-21 20:27:01 +00002394- Issue #2222: Fixed reference leak when occurred os.rename()
Hirokazu Yamamoto7f30a682008-08-17 09:46:56 +00002395 fails unicode conversion on 2nd parameter. (windows only)
2396
Facundo Batista94f243a2008-08-17 03:38:39 +00002397- Issue 2464. urllib2 now supports a malformation in the URL received
2398 in a redirect.
2399
Brett Cannonabe423e2008-08-16 21:47:07 +00002400- Silence the DeprecationWarning raised when importing mimetools in
Brett Cannon721b1452008-08-16 22:00:27 +00002401 BaseHTTPServer, cgi (and rfc822), httplib.
Brett Cannonabe423e2008-08-16 21:47:07 +00002402
Facundo Batistaeb90b782008-08-16 14:44:07 +00002403- Issue #2776: fixed small issue when handling an URL with double slash
2404 after a 302 response in the case of not going through a proxy.
2405
Antoine Pitroub90a8be2008-08-15 21:03:21 +00002406- Issue #2676: in the email package, content-type parsing was hanging on
2407 pathological input because of quadratic or exponential behaviour of a
2408 regular expression.
2409
Antoine Pitrou11ec65d2008-08-14 21:04:30 +00002410- Issue #3476: binary buffered reading through the new "io" library is now
2411 thread-safe.
2412
Brett Cannonbf3157b2008-08-14 05:00:03 +00002413- Silence the DeprecationWarning of rfc822 when it is imported by mimetools
2414 since mimetools itself is deprecated. Because modules are cached, all
2415 subsequent imports of rfc822 will not raise a visible DeprecationWarning.
2416
Antoine Pitrou9fcd4b32008-08-11 17:21:36 +00002417- Issue #3134: shutil referenced undefined WindowsError symbol.
2418
Robert Schuppenies14646332008-08-10 11:01:53 +00002419- Issue #1342811: Fix leak in Tkinter.Menu.delete. Commands associated to
2420 menu entries were not deleted.
2421
Brett Cannon83e81842008-08-09 23:30:55 +00002422- Copied the implementation of reduce() to _functools.reduce() to have a
2423 version that did not raise a DeprecationWarning under -3.
2424
Antoine Pitrou76b8bee2008-08-09 17:27:23 +00002425- Issue #3205: When iterating over a BZ2File fails allocating memory, raise
2426 a MemoryError rather than silently stop the iteration.
2427
Guido van Rossum59ce9012008-08-09 14:55:34 +00002428- Issue #3487: sre "bytecode" validator. Passing invalid "re-bytecode"
2429 to _sre.compile() will now be rejected. This should not affect anybody
2430 since the re.compile() function never generates invalid re-bytecode.
2431
Skip Montanaroa032bf42008-08-08 22:52:51 +00002432- Issue #3436: Make csv.DictReader's fieldnames attribute a property so that
2433 upon first access it can be automatically initialized from the csv file if
2434 it wasn't initialized during instantiation.
2435
Brett Cannon3aa2a492008-08-06 22:28:09 +00002436- Issue #2338: Create imp.reload() to help with transitioning to Python 3.0 as
2437 the reload() built-in has been removed.
2438
Brett Cannon7e30b672008-08-04 21:52:25 +00002439- Changed code in the following modules/packages to remove warnings raised
Brett Cannonc1b76e42008-08-09 23:06:16 +00002440 while running under the ``-3`` flag: aifc, asynchat, asyncore, bdb, bsddb,

2443 pstats, pydoc, re, rlcompleter, SimpleXMLRPCServer, shelve, socket,
2444 subprocess, sqlite3, tarfile, Tkinter, test.test_support, textwrap,
2445 threading, tokenize, traceback, urlparse, wsgiref, xml, xmlrpclib.
Brett Cannon7e30b672008-08-04 21:52:25 +00002446
Lars Gustäbel727bd0b2008-08-02 11:26:39 +00002447- Issue #3039: Fix tarfile.TarFileCompat.writestr() which always
2448 raised an AttributeError.
2449
Benjamin Peterson01a24322008-07-28 23:35:27 +00002450- Issue #2523: Fix quadratic behaviour when read()ing a binary file without
Antoine Pitroude781a42008-08-09 12:43:23 +00002451 asking for a specific length. This problem only affected files opened
2452 using the new "io" module, not the built-in open() function.
Benjamin Peterson01a24322008-07-28 23:35:27 +00002453
Mark Dickinsonfe84cce2008-07-27 06:39:07 +00002454- Issue #3449: Update decimal module to use most recent specification
2455 (v. 1.68) and tests (v. 2.58) from IBM.
2456
Skip Montanarof9ac43f2008-07-27 00:50:41 +00002457- Issue 3437: Bug fix in robotparser parsing of Allow: lines.
2458

2465
2466- Issue #3303: Fix a crash in locale.strcoll() when calling it with
2467 invalid arguments.
2468
2469- Issue #3302: Fix several crashes when calling locale's gettext functions
2470 with None arguments.
2471
2472- Issue #3389: Allow resolving dotted names for handlers in logging
2473 configuration files.
2474
2475- Deprecate the sunaudio module for removal in Python 3.0.
2476
Antoine Pitrou5fdfa3e2008-07-25 19:42:26 +00002477- Issue #3394: zipfile.writestr sets external attributes when passed a
2478 file name rather than a ZipInfo instance, so files are extracted with
2479 mode 0600 rather than 000 under Unix.
2480
Gregory P. Smitha36f8fe2008-08-04 00:13:29 +00002481- Issue #1857: subprocess.Popen.poll gained an additional _deadstate keyword
2482 argument in python 2.5, this broke code that subclassed Popen to include its
2483 own poll method. Fixed my moving _deadstate to an _internal_poll method.

Nick Coghlan6e8fef02008-08-18 13:14:22 +00002493- Issue #2235: the C API function PyObject_HashNotImplemented and its
2494 interaction with the tp_hash slot (added in 2.6b2) are now documented
2495
Nick Coghlan2a0c2b12008-08-04 12:47:17 +00002496- Issue #643841: The language reference now provides more detailed
2497 coverage of the lookup process for special methods. The disclaimers
2498 regarding lack of coverage of new-style classes have also been
2499 removed, since the coverage is now fairly reasonable.

Raymond Hettingere3ae6552008-06-20 04:18:15 +00002502What's New in Python 2.6 beta 2?
2503================================
2504
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00002505*Release date: 17-Jul-2008*
2506
Raymond Hettingere3ae6552008-06-20 04:18:15 +00002507Core and Builtins
2508-----------------
2509
Georg Brandl3e483f62008-07-16 22:57:41 +00002510- Issue #3156: Fix inconsistent behavior of the bytearray type: all
2511 its methods now allow for items objects that can be converted to
2512 an integer using operator.index().
2513
Mark Dickinson64b7e502008-07-16 09:40:03 +00002514- Issue #3360: Fix incorrect parsing of '020000000000.0', which
2515 produced a ValueError instead of giving the correct float.
2516
Eric Smitha5fa5a22008-07-16 00:11:49 +00002517- Issue #3083: Add alternate (#) formatting for bin, oct, hex output
2518 for str.format(). This adds the prefix 0b, 0o, or 0x, respectively.
2519
Mark Dickinson7103aa42008-07-15 19:08:33 +00002520- Issue #3008: the float type has a new instance method 'float.hex'
2521 and a new class method 'float.fromhex' to convert floating-point
2522 numbers to and from hexadecimal strings, respectively.
2523
Nick Coghlan6d6bd442008-07-15 15:40:22 +00002524- Issue #2235: __hash__ is once again inherited by default. To allow
2525 collections.Hashable to remain meaningful in the presence of the
2526 default hash implementation (object.__hash__), it is now possible
2527 to explicit block inheritance of hash by setting __hash__=None at
2528 the Python level, or tp_hash=PyObject_HashNotImplemented at the C
2529 level.
2530
Nick Coghlanb028f502008-07-13 14:52:36 +00002531- Issue #3221: Issue a RuntimeWarning instead of raising SystemError if
2532 the parent module cannot be found while performing an absolute import.
2533 This means that an incorrectly defined __package__ attribute will
2534 now only prevent relative imports in that module rather than causing
2535 all imports from that module to fail.
2536
Nick Coghlan14ff9942008-07-08 14:21:42 +00002537- Issue #2517: Allow unicode messages in Exceptions again by correctly
2538 bypassing the instance dictionary when looking up __unicode__ on
2539 new-style classes.
2540
Amaury Forgeot d'Arcbdd941f2008-07-01 20:38:04 +00002541- Issue #3242: Fix a crash inside the print statement, if sys.stdout is
2542 set to a custom object whose write() method happens to install
2543 another file in sys.stdout.
2544
Amaury Forgeot d'Arc1f40c8a2008-06-30 22:42:40 +00002545- Issue #3088: Corrected a race condition in classes derived from
2546 threading.local: the first member set by a thread could be saved in
2547 another thread's dictionary.
2548
Mark Dickinson1ec2fcd2008-06-20 14:53:43 +00002549- Issue #3004: Minor change to slice.indices(): the start and stop
2550 arguments are now treated identically, making the behaviour easier
2551 to describe and understand. For example, slice(None, -10,
2552 1).indices(9) now returns (0, 0, 1) instead of (0, -1, 1), and
2553 slice(None, 10, -1).indices(10) returns (9, 9, -1) instead of (9,
2554 10, -1).
2555
Georg Brandl278fc502008-07-19 12:46:12 +00002556- Issue #3219: Calling a function with repeated keyword arguments,
2557 f(a=2, a=23), would not cause a syntax error. This was a regression
2558 from 2.4 caused by the switch to the new compiler.

Georg Brandl278fc502008-07-19 12:46:12 +00002560- Issue #2862: Make int and float freelist management consistent with
2561 other freelists. Changes their CompactFreeList apis into

3057 two handlers that derive the same default base class.

Georg Brandl3ee81df2008-05-17 18:14:43 +00003070- Issue #1631171: Re-implement the 'warnings' module in C (the
3071 original Python code has been kept as backup). This will allow for
3072 using the 'warning's machinery in such places as the parser where
3073 use of pure Python code is not possible. Both the ``showarning()``
3074 and ``formatwarning()`` gain an optional 'line' argument which is
3075 not called by default for backwards-compatibility reasons. Setting
3076 ``warnings.showwarning()`` to an implementation that lacks support
3077 for the ``line`` argument will raise a DeprecationWarning.

Georg Brandl3ee81df2008-05-17 18:14:43 +00003140- Issue #2550: The approach used by client/server code for obtaining
3141 ports to listen on in network-oriented tests has been refined in an
3142 effort to facilitate running multiple instances of the entire
3143 regression test suite in parallel without issue.
3144 test_support.bind_port() has been fixed such that it will always
3145 return a unique port -- which wasn't always the case with the
3146 previous implementation, especially if socket options had been set
3147 that affected address reuse (i.e. SO_REUSEADDR, SO_REUSEPORT). The
3148 new implementation of bind_port() will actually raise an exception
3149 if it is passed an AF_INET/SOCK_STREAM socket with either the
3150 SO_REUSEADDR or SO_REUSEPORT socket option set. Furthermore, if
3151 available, bind_port() will set the SO_EXCLUSIVEADDRUSE option on
3152 the socket it's been passed. This currently only applies to
3153 Windows. This option prevents any other sockets from binding to the
3154 host/port we've bound to, thus removing the possibility of the
3155 'non-deterministic' behaviour, as Microsoft puts it, that occurs
3156 when a second SOCK_STREAM socket binds and accepts to a host/port
3157 that's already been bound by another socket. The optional preferred
3158 port parameter to bind_port() has been removed. Under no
3159 circumstances should tests be hard coding ports!
3160
3161 test_support.find_unused_port() has also been introduced, which will
3162 pass a temporary socket object to bind_port() in order to obtain an
3163 unused port. The temporary socket object is then closed and
3164 deleted, and the port is returned. This method should only be used
3165 for obtaining an unused port in order to pass to an external program
3166 (i.e. the -accept [port] argument to openssl's s_server mode) or as
3167 a parameter to a server-oriented class that doesn't give you direct
3168 access to the underlying socket used.
3169
3170 Finally, test_support.HOST has been introduced, which should be used
3171 for the host argument of any relevant socket calls (i.e. bind and
3172 connect).
Trent Nelsone41b0062008-04-08 23:47:30 +00003173
3174 The following tests were updated to following the new conventions:
Georg Brandl3ee81df2008-05-17 18:14:43 +00003175 test_socket, test_smtplib, test_asyncore, test_ssl, test_httplib,
Trent Nelsone41b0062008-04-08 23:47:30 +00003176 test_poplib, test_ftplib, test_telnetlib, test_socketserver,
3177 test_asynchat and test_socket_ssl.
3178
Georg Brandl3ee81df2008-05-17 18:14:43 +00003179 It is now possible for multiple instances of the regression test
3180 suite to run in parallel without issue.

3448
Fred Drakea8ee94b2008-03-01 02:45:07 +00003449- Issue #2051: pyc and pyo files are no longer created with permission
Barry Warsaw52973612008-03-01 02:23:38 +00003450 644. The mode is now inherited from the py file.
Christian Heimes40346852008-02-23 17:52:07 +00003451
Georg Brandlad61bc82008-02-23 15:11:18 +00003452- Issue #2067: file.__exit__() now calls subclasses' close() method.
3453
3454- Patch #1759: Backport of PEP 3129 class decorators.
Christian Heimes5224d282008-02-23 15:01:05 +00003455
Vinay Sajipb7edfc42008-04-02 21:10:23 +00003456- Issue #1881: An internal parser limit has been increased. Also see
Facundo Batistafc2d0102008-02-23 12:01:13 +00003457 issue 215555 for a discussion.
3458
Eric Smitha73fbe72008-02-23 03:09:44 +00003459- Added the future_builtins module, which contains hex() and oct().
3460 These are the PEP 3127 version of these functions, designed to be
3461 compatible with the hex() and oct() builtins from Python 3.0. They
3462 differ slightly in their output formats from the existing, unchanged
3463 Python 2.6 builtins. The expected usage of the future_builtins
3464 module is:
3465 from future_builtins import hex, oct
3466
Eric Smith7ef40bf2008-02-20 23:34:22 +00003467- Issue #1600: Modifed PyOS_ascii_formatd to use at most 2 digit
3468 exponents for exponents with absolute value < 100. Follows C99
3469 standard. This is a change on Windows, which would use 3 digits.
3470 Also, added 'n' to the formats that PyOS_ascii_formatd understands,
3471 so that any alterations it does to the resulting string will be
3472 available in stringlib/formatter.h (for float.__format__).
3473
Eric Smith5a3c1352008-02-19 13:21:56 +00003474- Implemented PEP 3101, Advanced String Formatting. This adds a new
3475 builtin format(); a format() method for str and unicode; a
3476 __format__() method to object, str, unicode, int, long, float, and
3477 datetime; the class string.Formatter; and the C API
3478 PyObject_Format().
3479
Georg Brandl3ee81df2008-05-17 18:14:43 +00003480- Fixed several potential crashes, all caused by specially crafted
3481 __del__ methods exploiting objects in temporarily inconsistent
3482 state.
Amaury Forgeot d'Arc632fad32008-02-16 20:55:24 +00003483
Vinay Sajipb7edfc42008-04-02 21:10:23 +00003484- Issue #2115: Important speedup in setting __slot__ attributes. Also
Georg Brandl3ee81df2008-05-17 18:14:43 +00003485 prevent a possible crash: an Abstract Base Class would try to access
3486 a slot on a registered virtual subclass.
Amaury Forgeot d'Arc60d6c7f2008-02-15 21:22:45 +00003487
Georg Brandl3ee81df2008-05-17 18:14:43 +00003488- Fixed repr() and str() of complex numbers with infinity or nan as
3489 real or imaginary part.
Christian Heimes2f0da532008-02-15 06:57:08 +00003490
Georg Brandl3ee81df2008-05-17 18:14:43 +00003491- Clear all free lists during a gc.collect() of the highest generation
3492 in order to allow pymalloc to free more arenas. Python may give back
3493 memory to the OS earlier.
Christian Heimes3b718a72008-02-14 12:47:33 +00003494
Georg Brandl3ee81df2008-05-17 18:14:43 +00003495- Issue #2045: Fix an infinite recursion triggered when printing a
3496 subclass of collections.defaultdict, if its default_factory is set
3497 to a bound method.
Amaury Forgeot d'Arcb01aa432008-02-08 00:56:02 +00003498
Christian Heimesf75dbef2008-02-08 00:11:31 +00003499- Fixed a minor memory leak in dictobject.c. The content of the free
3500 list was not freed on interpreter shutdown.
3501
Georg Brandl3ee81df2008-05-17 18:14:43 +00003502- Limit free list of method and builtin function objects to 256
3503 entries each.
Christian Heimes6075a822008-02-06 12:44:34 +00003504
Georg Brandl3ee81df2008-05-17 18:14:43 +00003505- Patch #1953: Added ``sys._compact_freelists()`` and the C API
3506 functions ``PyInt_CompactFreeList`` and ``PyFloat_CompactFreeList``
Christian Heimes422051a2008-02-04 18:00:12 +00003507 to compact the internal free lists of pre-allocted ints and floats.
3508
Georg Brandl3ee81df2008-05-17 18:14:43 +00003509- Issue #1983: Fixed return type of fork(), fork1() and forkpty()
3510 calls. Python expected the return type int but the fork familie
3511 returns pi_t.
Christian Heimes951cc0f2008-01-31 23:08:23 +00003512
Georg Brandl3ee81df2008-05-17 18:14:43 +00003513- Issue #1678380: Fix a bug that identifies 0j and -0j when they
3514 appear in the same code unit.
Mark Dickinson105be772008-01-31 22:17:37 +00003515

3523 the internal lookup cache for ref leak tests.
Christian Heimes908caac2008-01-27 23:34:59 +00003524
Georg Brandl3ee81df2008-05-17 18:14:43 +00003525- Patch #1473257: generator objects gain a gi_code attribute. This is
3526 the same object as the func_code attribute of the function that
3527 produced the generator.
Georg Brandl0cdf9a32008-01-26 14:14:20 +00003528
Georg Brandl3ee81df2008-05-17 18:14:43 +00003529- Issue #1920: "while 0" statements were completely removed by the
3530 compiler, even in the presence of an "else" clause, which is
3531 supposed to be run when the condition is false. Now the compiler
3532 correctly emits bytecode for the "else" suite.
Amaury Forgeot d'Arc31eaafe2008-01-24 22:59:25 +00003533
Guido van Rossumeead05f2008-01-24 18:21:02 +00003534- A few crashers fixed: weakref_in_del.py (issue #1377858);
3535 loosing_dict_ref.py (issue #1303614, test67.py);
3536 borrowed_ref_[34].py (not in tracker).
3537
Vinay Sajipd7cf32e2008-01-24 12:43:33 +00003538- Issue #1069410: The "can't load dll" message box on Windows is
Christian Heimesb2302ba2008-01-23 17:15:06 +00003539 suppressed while an extension is loaded by calling SetErrorMode in
3540 dynload_win.c. The error is still reported properly.
3541
Georg Brandl3ee81df2008-05-17 18:14:43 +00003542- Issue #1915: Python compiles with --enable-unicode=no again. However
Christian Heimes082c9b02008-01-23 14:20:50 +00003543 several extension methods and modules do not work without unicode
3544 support.
3545
Georg Brandl26543b12008-01-21 18:36:51 +00003546- Issue #1882: when compiling code from a string, encoding cookies in the
3547 second line of code were not always recognized correctly.
3548
Georg Brandl14404b62008-01-19 19:27:05 +00003549- Issue #1679: "0x" was taken as a valid integer literal.
3550
Georg Brandl6caad7d2008-01-26 14:19:22 +00003551- Issue #1865: ``bytes`` as an alias for ``str`` and b"" as an alias "" were
Christian Heimes288e89a2008-01-18 18:24:07 +00003552 added.
3553
Christian Heimesc94e2b52008-01-14 04:13:37 +00003554- sys.float_info / PyFloat_GetInfo: The floating point information
3555 object was converted from a dict to a specialized structseq object.
3556
Georg Brandl3ee81df2008-05-17 18:14:43 +00003557- Patch #1816: Added sys.flags structseq. It exposes the status of
3558 most command line arguments and PYTHON* environment variables.
Christian Heimesf31b69f2008-01-14 03:42:48 +00003559
Georg Brandl3ee81df2008-05-17 18:14:43 +00003560- Objects/structseq.c: Implemented new structseq representation. The
3561 patch makes structseqs (e.g. the return value of os.stat) more
3562 readable.
Christian Heimes9c201962008-01-14 03:33:52 +00003563
Georg Brandl3ee81df2008-05-17 18:14:43 +00003564- Patch #1700288: added a type attribute cache that caches method

Georg Brandl3ee81df2008-05-17 18:14:43 +00003586 and INF. float("nan"), float("inf") and float("-inf") now work on
3587 every platform with IEEE 754 semantics.
Christian Heimes0a8143f2007-12-18 23:22:54 +00003588
Georg Brandl3ee81df2008-05-17 18:14:43 +00003589- Compiler now generates simpler and faster code for dictionary
3590 literals. The oparg for BUILD_MAP now indicates an estimated
3591 dictionary size. There is a new opcode, STORE_MAP, for adding
3592 entries to the dictionary.

3622 file can now be directly executed by passing their name to the
3623 interpreter. The directory/zipfile is automatically inserted as the
3624 first entry in sys.path.
Nick Coghlan327a39b2007-11-18 11:56:28 +00003625
Georg Brandl3ee81df2008-05-17 18:14:43 +00003626- Issue #1265: Fix a problem with sys.settrace, if the tracing
3627 function uses a generator expression when at the same time the
3628 executed code is closing a paused generator.
Amaury Forgeot d'Arc0d75f092007-11-13 21:54:28 +00003629
Raymond Hettinger1760c8a2007-11-08 02:52:43 +00003630- sets and frozensets now have an isdisjoint() method.
3631
Raymond Hettinger3f8caa32007-10-24 01:28:33 +00003632- optimize the performance of builtin.sum().
3633
Neal Norwitz44f326e2007-10-05 05:29:17 +00003634- Fix warnings found by the new version of the Coverity checker.
3635
Georg Brandl3ee81df2008-05-17 18:14:43 +00003636- The enumerate() builtin function is no longer bounded to sequences
3637 smaller than LONG_MAX. Formerly, it raised an OverflowError. Now,
3638 automatically shifts from ints to longs.
Raymond Hettinger8f669372007-10-03 21:18:11 +00003639
Georg Brandl3ee81df2008-05-17 18:14:43 +00003640- Issue #1686386: Tuple's tp_repr did not take into account the
3641 possibility of having a self-referential tuple, which is possible
3642 from C code. Nor did object's tp_str consider that a type's tp_str
3643 could do something that could lead to an inifinite recursion.
3644 Py_ReprEnter() and Py_EnterRecursiveCall(), respectively, fixed the
3645 issues.
Brett Cannon0b14f242007-09-30 19:45:10 +00003646
Georg Brandl3ee81df2008-05-17 18:14:43 +00003647- Issue #1164: It was possible to trigger deadlock when using the
3648 'print' statement to write to a file since the GIL was not released
3649 as needed. Now PyObject_Print() does the right thing along with
3650 various tp_print implementations of the built-in types and those in
3651 the collections module.
Brett Cannon01531592007-09-17 03:28:34 +00003652
Georg Brandl3ee81df2008-05-17 18:14:43 +00003653- Issue #1147: Exceptions were directly allowing string exceptions in
3654 their throw() method even though string exceptions no longer
3655 allowed.
Brett Cannon4c20bc42007-09-11 21:02:28 +00003656
Georg Brandl3ee81df2008-05-17 18:14:43 +00003657- Issue #1096: Prevent a segfault from getting the repr of a very
3658 deeply nested list by using the recursion counter.
Brett Cannona0c05512007-09-10 21:38:27 +00003659
Brett Cannon1e534b52007-09-07 04:18:30 +00003660- Issue #1202533: Fix infinite recursion calls triggered by calls to
Georg Brandl3ee81df2008-05-17 18:14:43 +00003661 PyObject_Call() never calling back out to Python code to trigger
3662 recursion depth updates/checks. Required the creation of a static
3663 RuntimeError instance in case normalizing an exception put the
3664 recursion check value past its limit. Fixes crashers
3665 infinite_rec_(1|2|4|5).py.
Brett Cannon1e534b52007-09-07 04:18:30 +00003666
Georg Brandl3ee81df2008-05-17 18:14:43 +00003667- Patch #1031213: Decode source line in SyntaxErrors back to its
3668 original source encoding.

Georg Brandl7c3b50d2007-07-12 08:38:00 +00003670- Patch #1673759: add a missing overflow check when formatting floats
3671 with %G.
3672
Georg Brandl3ee81df2008-05-17 18:14:43 +00003673- Prevent expandtabs() on string and unicode objects from causing a
3674 segfault when a large width is passed on 32-bit platforms.
Neal Norwitz7dbd2a32007-06-09 03:36:34 +00003675

Georg Brandl3ee81df2008-05-17 18:14:43 +00003678- Issue #1722485: remove docstrings again when running with -OO.
Georg Brandla5ea6892007-06-01 11:33:33 +00003679
Neal Norwitz0ac60192007-05-27 04:08:54 +00003680- Add new attribute names for function objects. All the func_* become
Georg Brandl3ee81df2008-05-17 18:14:43 +00003681 __*__ attributes. (Some already existed, e.g., __doc__ and
3682 __name__.)
Neal Norwitz0ac60192007-05-27 04:08:54 +00003683
Neal Norwitz8b2bfbc2007-05-23 06:35:32 +00003684- Add -3 option to the interpreter to warn about features that are
3685 deprecated and will be changed/removed in Python 3.0.
3686
Georg Brandl2134e752007-05-21 20:34:16 +00003687- Patch #1686487: you can now pass any mapping after '**' in function
3688 calls.
3689
Collin Winter62903052007-05-18 23:11:24 +00003690- except clauses may now be spelled either "except E, target:" or
Georg Brandl3ee81df2008-05-17 18:14:43 +00003691 "except E as target:". This is to provide forwards compatibility
3692 with Python 3.0.
Collin Winter62903052007-05-18 23:11:24 +00003693
Brett Cannon229cee22007-05-05 01:34:02 +00003694- Deprecate BaseException.message as per PEP 352.
3695
Georg Brandl3ee81df2008-05-17 18:14:43 +00003696- Issue #1303614: don't expose object's __dict__ when the dict is
Armin Rigo9790a272007-05-02 19:23:31 +00003697 inherited from a builtin base.
3698
Vinay Sajip8549ce32007-05-06 17:53:37 +00003699- When __slots__ are set to a unicode string, make it work the same as
Neal Norwitzcbd9ee62007-04-14 05:25:50 +00003700 setting a plain string, ie don't expand to single letter identifiers.
3701
Raymond Hettinger13936692007-04-11 18:40:58 +00003702- Request #1191699: Slices can now be pickled.
3703
Raymond Hettinger4db5fe92007-04-12 04:10:00 +00003704- Request #1193128: str.translate() now allows a None argument for
3705 translations that only remove characters without re-mapping the
3706 remaining characters.
3707
Georg Brandl5cb76c12007-03-21 09:00:39 +00003708- Patch #1682205: a TypeError while unpacking an iterable is no longer
3709 masked by a generic one with the message "unpack non-sequence".
3710
Neal Norwitzaa754b72007-03-21 06:39:48 +00003711- Remove unused file Python/fmod.c.
3712
Guido van Rossum143b5642007-03-23 04:58:42 +00003713- Bug #1683368: The object.__init__() and object.__new__() methods are
3714 now stricter in rejecting excess arguments. The only time when
3715 either allows excess arguments is when it is not overridden and the
3716 other one is. For backwards compatibility, when both are
3717 overridden, it is a deprecation warning (for now; maybe a Py3k
Guido van Rossum234b1ff2007-03-23 19:39:01 +00003718 warning later). Also, type.__init__() insists on the same signature
3719 as supported by type.__new__().
Guido van Rossum143b5642007-03-23 04:58:42 +00003720
Georg Brandl3ee81df2008-05-17 18:14:43 +00003721- Patch #1675423: PyComplex_AsCComplex() now tries to convert an
3722 object to complex using its __complex__() method before falling back
3723 to the __float__() method. Therefore, the functions in the cmath
3724 module now can operate on objects that define a __complex__()
3725 method.
Georg Brandl2b869942007-03-17 16:08:45 +00003726
Georg Brandl3ee81df2008-05-17 18:14:43 +00003727- Patch #1623563: allow __class__ assignment for classes with
3728 __slots__. The old and the new class are still required to have the
3729 same slot names.
Žiga Seilnacht6f2d09c2007-03-16 11:59:38 +00003730
Georg Brandl3ee81df2008-05-17 18:14:43 +00003731- Patch #1642547: Fix an error/crash when encountering syntax errors

Georg Brandl3ee81df2008-05-17 18:14:43 +00003734- Patch #1462488: Python no longer segfaults when
3735 ``object.__reduce_ex__()`` is called with an object that is faking
3736 its type.
Žiga Seilnacht20f43d32007-03-15 11:44:55 +00003737
Georg Brandl3ee81df2008-05-17 18:14:43 +00003738- Patch #1680015: Don't modify __slots__ tuple if it contains an
3739 unicode name.

Georg Brandl5240d742007-03-13 20:46:32 +00003741- Patch #1444529: the builtin compile() now accepts keyword arguments.
3742
Georg Brandl7b9c5552007-03-12 14:30:05 +00003743- Bug #1678647: write a newline after printing an exception in any
3744 case, even when converting the value to a string failed.
3745
Georg Brandl871f1bc2007-03-12 13:17:36 +00003746- The dir() function has been extended to call the __dir__() method on
Georg Brandl3ee81df2008-05-17 18:14:43 +00003747 its argument, if it exists. If not, it will work like before. This
3748 allows customizing the output of dir() in the presence of a
3749 __getattr__().
Georg Brandl871f1bc2007-03-12 13:17:36 +00003750
Collin Winter276887b2007-03-12 16:11:39 +00003751- Patch #922167: Python no longer segfaults when faced with infinitely
3752 self-recursive reload() calls (as reported by bug #742342).
3753
Georg Brandl3ee81df2008-05-17 18:14:43 +00003754- Patch #1675981: remove unreachable code from ``type.__new__()``
3755 method.
Žiga Seilnacht89032082007-03-11 15:54:54 +00003756
Georg Brandl3ee81df2008-05-17 18:14:43 +00003757- Patch #1491866: change the complex() constructor to allow
3758 parthensized forms. This means complex(repr(x)) now works instead of
3759 raising a ValueError.
Collin Wintere38051d2007-03-09 20:33:07 +00003760
Georg Brandlaa2321b2007-03-07 00:40:28 +00003761- Patch #703779: unset __file__ in __main__ after running a file. This
Georg Brandl3ee81df2008-05-17 18:14:43 +00003762 makes the filenames the warning module prints much more sensible
3763 when a PYTHONSTARTUP file is used.
Georg Brandlaa2321b2007-03-07 00:40:28 +00003764
Georg Brandl49aafc92007-03-07 00:34:46 +00003765- Variant of patch #697613: don't exit the interpreter on a SystemExit
3766 exception if the -i command line option or PYTHONINSPECT environment
Georg Brandl3ee81df2008-05-17 18:14:43 +00003767 variable is given, but break into the interactive interpreter just
3768 like on other exceptions or normal program exit.

Georg Brandl3ee81df2008-05-17 18:14:43 +00003773- Bug #1674503: close the file opened by execfile() in an error
3774 condition.
Georg Brandl098cd692007-03-06 12:17:50 +00003775
Georg Brandl0fca97a2007-03-05 22:28:08 +00003776- Patch #1674228: when assigning a slice (old-style), check for the
3777 sq_ass_slice instead of the sq_slice slot.
3778
Georg Brandl3ee81df2008-05-17 18:14:43 +00003779- When printing an unraisable error, don't print exceptions. before
3780 the name. This duplicates the behavior whening normally printing
3781 exceptions.
Neal Norwitz88516a62007-02-26 22:41:45 +00003782
Georg Brandl3ee81df2008-05-17 18:14:43 +00003783- Bug #1653736: Properly discard third argument to

Georg Brandl3ee81df2008-05-17 18:14:43 +00003789- Bug #1377858: Fix the segfaulting of the interpreter when an object
3790 created a weakref on itself during a __del__ call for new-style
3791 classes (classic classes still have the bug).
Brett Cannonf5bee302007-01-23 23:21:22 +00003792
Martin v. Löwis6c5c5022007-01-23 21:11:47 +00003793- Bug #1579370: Make PyTraceBack_Here use the current thread, not the

Georg Brandl2c1375c2006-10-12 11:27:59 +00003831- Bug #1545497: when given an explicit base, int() did ignore NULs
3832 embedded in the string to convert.
3833
Georg Brandl846f73a2006-10-08 07:11:54 +00003834- Bug #1569998: break inside a try statement (outside a loop) is now
3835 recognized and rejected.

3838
Armin Rigo7ccbca92006-10-04 12:17:45 +00003839- A number of places, including integer negation and absolute value,
3840 were fixed to not rely on undefined behaviour of the C compiler
3841 anymore.
Martin v. Löwis820d6ac2006-10-04 05:47:34 +00003842
Georg Brandl3267d282006-09-30 09:03:42 +00003843- Bug #1566800: make sure that EnvironmentError can be called with any
3844 number of arguments, as was the case in Python 2.4.
3845
Georg Brandl5d59c092006-09-30 08:43:30 +00003846- Patch #1567691: super() and new.instancemethod() now don't accept
Georg Brandl3ee81df2008-05-17 18:14:43 +00003847 keyword arguments any more (previously they accepted them, but
3848 didn't use them).

Georg Brandl3ee81df2008-05-17 18:14:43 +00003850- Fix a bug in the parser's future statement handling that led to
3851 "with" not being recognized as a keyword after, e.g., this
3852 statement: from __future__ import division, with_statement
Georg Brandla10d3af2006-09-24 12:35:36 +00003853

4409 -- the failure just occurred later, with a more cumbersome
4410 exception.

Georg Brandl3ee81df2008-05-17 18:14:43 +00004691- Issue #829951: In the smtplib module, SMTP.starttls() now complies
4692 with RFC 3207 and forgets any knowledge obtained from the server not
4693 obtained from the TLS negotiation itself. Patch contributed by Bill
4694 Fenner.
Gregory P. Smith2b3ba582008-01-17 08:03:17 +00004695
Georg Brandl3ee81df2008-05-17 18:14:43 +00004696- Issue #1339: The smtplib.SMTP class has been refactored a bit such
Gregory P. Smithbde4ae42008-01-17 08:35:49 +00004697 that the SMTP.starttls() caller no longer needs to call ehlo()
4698 beforehand. SMTP.starttls() now raises an exception of the server
Georg Brandl3ee81df2008-05-17 18:14:43 +00004699 does not claim to support starttls. Adds the
4700 SMTP.ehlo_or_helo_if_needed() method. Patch contributed by Bill
4701 Fenner.

4781 complex, tuple, list, dict, set, and frozenset. Formerly, it would
4782 silently miscode subclasses of those types. Now, it raises a

Raymond Hettinger12e94202007-11-07 01:13:09 +00004784

Georg Brandl3ee81df2008-05-17 18:14:43 +00004799 time so that opening a database previously created with the DB_DUP
4800 or DB_DUPSORT flag set will keep the proper behavior on subsequent
4801 opens. Specifically: dictionary assignment to a DB object will
4802 replace all values for a given key when the database allows
4803 duplicate values. DB users should use DB.put(k, v) when they want
4804 to store duplicates; not DB[k] = v.
Gregory P. Smithec10a4a2007-11-05 02:32:26 +00004805

4811 characters with ASCII value less than 32. Also, it correctly quotes
4812 dots only if they occur on a single line, as opposed to the previous
4813 behavior of quoting dots if they are the second character of any
4814 line.
Georg Brandl4aef7272007-03-13 22:49:43 +00004815

5137-----
5138
Georg Brandl3ee81df2008-05-17 18:14:43 +00005139- Unified naming convention for free lists and their limits. All free
5140 lists in Object/ are named ``free_list``, the counter ``numfree``
5141 and the upper limit is a macro ``PyName_MAXFREELIST`` inside an
5142 #ifndef block.
Christian Heimes5b970ad2008-02-06 13:33:44 +00005143
Georg Brandl3ee81df2008-05-17 18:14:43 +00005144- ``PySet_Add()`` can now modify a newly created frozenset. Similarly
5145 to ``PyTuple_SetItem``, it can be used to populate a brand new
5146 frozenset; but it does not steal a reference to the added item.

5158
Georg Brandl3ee81df2008-05-17 18:14:43 +00005159- Issue #1521: On 64bit platforms, using PyArgs_ParseTuple with the t#
5160 of w# format code incorrectly truncated the length to an int, even
5161 when PY_SSIZE_T_CLEAN is set. The str.decode method used to return
5162 incorrect results with huge strings.
Georg Brandl6caad7d2008-01-26 14:19:22 +00005163
Georg Brandl3ee81df2008-05-17 18:14:43 +00005164- Issue #1629: Renamed Py_Size, Py_Type and Py_Refcnt to Py_SIZE,

5182- Fix some leftovers from the conversion from int to Py_ssize_t
5183 (relevant to strings and sequences of more than 2**31 items).
5184
5185- Make _PyGILState_NoteThreadState() static, it was not used anywhere
5186 outside of pystate.c and should not be necessary.
5187
Georg Brandl3ee81df2008-05-17 18:14:43 +00005188- ``PyImport_Import`` and ``PyImport_ImportModule`` now always do
5189 absolute imports. In earlier versions they might have used relative
5190 imports under some conditions.
Christian Heimes000a0742008-01-03 22:16:32 +00005191
Georg Brandl3ee81df2008-05-17 18:14:43 +00005192- Added case insensitive comparison methods ``PyOS_stricmp(char*,
5193 char*)`` and ``PyOS_strnicmp(char*, char*, Py_ssize_t)``.
Christian Heimes000a0742008-01-03 22:16:32 +00005194
Georg Brandl3ee81df2008-05-17 18:14:43 +00005195- Bug #1542693: remove semi-colon at end of PyImport_ImportModuleEx

5203 requires Windows 2000 or greater. The _WINVER and NTDDI_VERSION
5204 macros are set to Win2k for x86/32bit builds and WinXP for AMD64
5205 builds.
Christian Heimes95d64472008-02-09 19:55:22 +00005206

Georg Brandl3ee81df2008-05-17 18:14:43 +00005220- Removed the macfs module. It had been deprecated since Python 2.5.
5221 This lead to the deprecation of macostools.touched() as it relied
5222 solely on macfs and was a no-op under OS X.
