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.

46 the release file is empty.
47
Tarek Ziadéf14c7fc2010-01-24 00:33:32 +000048- Issue #7748: Since unicode values are supported for some metadata options
49 in Distutils, the DistributionMetadata get_* methods will now return an utf-8
50 encoded string for them. This ensure that the upload and register commands
51 send the right values to PyPI without any error.
52
R. David Murrayed44dfa2010-01-16 05:15:17 +000053- Issue #1670765: Prevent email.generator.Generator from re-wrapping

72
Tarek Ziadédc0f4872010-01-11 22:50:29 +000073- Issue #5372: Drop the reuse of .o files in Distutils' ccompiler (since

Benjamin Peterson4f51baf2009-12-05 18:40:02 +0000106What's New in Python 2.7 alpha 2?
107=================================

Benjamin Petersonaa7e51f2010-01-09 16:34:06 +0000109*Release date: 2010-01-09*
Benjamin Peterson4f51baf2009-12-05 18:40:02 +0000110
111Core and Builtins
112-----------------
113
Benjamin Petersonecdae192010-01-04 00:43:01 +0000114- The __complex__ method is now looked up on the class of instances to make it
115 consistent with other special methods.
116
Antoine Pitrou5b7139a2010-01-02 21:12:58 +0000117- Issue #7462: Implement the stringlib fast search algorithm for the `rfind`,
118 `rindex`, `rsplit` and `rpartition` methods. Patch by Florent Xicluna.
119
Mark Dickinson1b34d252010-01-01 17:27:30 +0000120- Issue #5080: A number of functions and methods previously produced a
121 DeprecationWarning when passed a float argument where an integer was
122 expected. These functions and methods now raise TypeError instead.
123 The majority of the effects of this change are in the extension
124 modules, but some core functions and methods are affected: notably
125 the 'chr', 'range' and 'xrange' builtins, and many unicode/str
126 methods.
127
Benjamin Peterson0f02d392009-12-30 19:34:10 +0000128- Issue #7604: Deleting an unset slotted attribute did not raise an
129 AttributeError.
130
Mark Dickinson99d652e2009-12-30 12:12:23 +0000131- Issue #7534: Fix handling of IEEE specials (infinities, nans,
132 negative zero) in ** operator. The behaviour now conforms to that
133 described in C99 Annex F.
134
Amaury Forgeot d'Arcc8a2ce72009-12-29 23:06:17 +0000135- Issue #7579: the msvcrt module now has docstrings for all its functions.
136
Amaury Forgeot d'Arc8645a5c2009-12-29 22:03:38 +0000137- Issue #7413: Passing '\0' as the separator to datetime.datetime.isoformat()
138 used to drop the time part of the result.
139
Mark Dickinson46572832009-12-27 14:55:57 +0000140- Issue #1811: improve accuracy and cross-platform consistency for
141 true division of integers: the result of a/b is now correctly
142 rounded for ints a and b (at least on IEEE 754 platforms), and in
143 particular does not depend on the internal representation of a long.
144
Ezio Melottif84caf42009-12-24 22:25:17 +0000145- Issue #6108: unicode(exception) and str(exception) should return the same
146 message when only __str__ (and not __unicode__) is overridden in the subclass.
147
Ronald Oussoren92919a62009-12-24 13:30:58 +0000148- Issue #6834: replace the implementation for the 'python' and 'pythonw'
149 executables on OSX.
150
151 These executables now work properly with the arch(1) command:
152 ``arch -ppc python`` will start a universal binary version of python
153 in PPC mode (unlike previous releases).
154
R. David Murray0a0a1a82009-12-14 16:28:26 +0000155- Issue #1680159: unicode coercion during an 'in' operation no longer masks
156 the underlying error when the coercion fails for the left hand operand.
157
Benjamin Peterson4895af42009-12-13 16:36:53 +0000158- Issue #7491: Metaclass's __cmp__ method was ignored.
159
Antoine Pitrou2a08b422009-12-13 16:18:14 +0000160- Issue #7466: segmentation fault when the garbage collector is called
Antoine Pitrou54584182010-01-07 17:54:10 +0000161 in the middle of populating a tuple. Patch by Florent Xicluna.

169 by Arfrever.
170
Antoine Pitrou80157252010-01-08 19:20:17 +0000171- Issue #7092: Remove py3k warning when importing cPickle. 2to3 handles
172 renaming of `cPickle` to `pickle`. The warning was annoying since there's
173 no alternative to cPickle if you care about performance. Patch by Florent
174 Xicluna.
175
Antoine Pitrou0d423b82010-01-07 17:46:49 +0000176- Issue #7455: Fix possible crash in cPickle on invalid input. Patch by

183 and make it implement the `io.BufferedIOBase` ABC to allow for further
184 speedups by wrapping it in an `io.BufferedReader`. Patch by Nir Aides.
185
186- Issue #3972: httplib.HTTPConnection now accepts an optional source_address
Gregory P. Smith9d325212010-01-03 02:06:07 +0000187 parameter to allow specifying where your connections come from.
188
Gregory P. Smith79a3eb12010-01-03 01:29:44 +0000189- socket.create_connection now accepts an optional source_address parameter.

192 Initial patch by Brian Curtin.
193
Ronald Oussorenca8e7ec2009-12-24 14:50:35 +0000194- Distutils now correctly identifies the build architecture as "x86_64"
Ezio Melotti569e61f2009-12-30 06:14:51 +0000195 when building on OSX 10.6 without "-arch" flags.

199
Tarek Ziadé2421d562009-12-20 23:23:34 +0000200- Issue #7552: Removed line feed in the base64 Authorization header in
201 the Distutils upload command to avoid an error when PyPI reads it.
202 This occurs on long passwords. Initial patch by JP St. Pierre.
203
204- Issue #7231: urllib2 cannot handle https with proxy requiring auth.
Senthil Kumaran7713acf2009-12-20 06:05:13 +0000205 Patch by Tatsuhiro Tsujikawa.
206
Benjamin Petersonddd392c2009-12-13 19:19:07 +0000207- Issue #7349: Make methods of file objects in the io module accept None as an
208 argument where file-like objects (ie StringIO and BytesIO) accept them to mean
209 the same as passing no argument.
210
Benjamin Petersonc4771d22009-12-13 17:31:31 +0000211- Issue #7348: StringIO.StringIO.readline(-1) now acts as if it got no argument
212 like other file objects.
213
Lars Gustäbel92ca7562009-12-13 11:32:27 +0000214- Issue #7357: tarfile no longer suppresses fatal extraction errors by

218
R. David Murray93321f32009-12-09 15:15:31 +0000219- Issue #5949: fixed IMAP4_SSL hang when the IMAP server response is

232 PyArg_ParseTupleAndKeywords, PyArg_VaParse,
233 PyArg_VaParseTupleAndKeywords and PyArg_Parse no longer accept float
234 arguments for integer format codes (other than 'L'): previously an
235 attempt to pass a float resulted in a DeprecationWarning; now it
236 gives a TypeError. For the 'L' format code (which previously had no
237 warning) there is now a DeprecationWarning.
238

281
Amaury Forgeot d'Arcd7288712009-12-01 21:51:04 +0000282- Issue #7419: setlocale() could crash the interpreter on Windows when called
283 with invalid values.
284
Eric Smithc4ab8332009-11-29 17:40:57 +0000285- Issue #3382: 'F' formatting for float and complex now convert the
286 result to upper case. This only affects 'inf' and 'nan', since 'f'
287 no longer converts to 'g' for large values.
Amaury Forgeot d'Arcd7288712009-12-01 21:51:04 +0000288
Mark Dickinson9dd5e162009-11-23 20:54:09 +0000289- Remove switch from "%f" formatting to "%g" formatting for floats
290 larger than 1e50 in absolute value.
291
Mark Dickinson18cfada2009-11-23 18:46:41 +0000292- Remove restrictions on precision when formatting floats. E.g.,
293 "%.120g" % 1e-100 used to raise OverflowError, but now gives the
294 requested 120 significant digits instead.
295
Benjamin Peterson89b1a5c2009-11-19 22:58:01 +0000296- Add Py3k warnings for parameter names in parenthesis.
297

Ronald Oussoren315cd0c2009-11-19 16:25:21 +0000300- Issue #7085: Fix crash when importing some extensions in a thread
301 on MacOSX 10.6.
302
Mark Dickinsonb678de82009-11-19 18:41:49 +0000303- Issue #7117: repr(x) for a float x returns a result based on the
304 shortest decimal string that's guaranteed to round back to x under
305 correct rounding (with round-half-to-even rounding mode).
306 Previously it gave a string based on rounding x to 17 decimal digits.
307 repr(x) for a complex number behaves similarly. On platforms where
308 the correctly-rounded strtod and dtoa code is not supported (see below),
309 repr is unchanged.

311- Issue #7117: On almost all platforms: float-to-string and
312 string-to-float conversions within Python are now correctly rounded.
313 Places these conversions occur include: str for floats and complex
314 numbers; the float and complex constructors; old-style and new-style
315 numeric formatting; serialization and deserialization of floats and
316 complex numbers using marshal, pickle and json; parsing of float and
317 imaginary literals in Python code; Decimal-to-float conversion.
318
319 The conversions use a Python-adapted version of David Gay's
320 well-known dtoa.c, providing correctly-rounded strtod and dtoa C
321 functions. This code is supported on Windows, and on Unix-like
322 platforms using gcc, icc or suncc as the C compiler. There may be a
323 small number of platforms on which correct operation of this code
324 cannot be guaranteed, so the code is not used: notably, this applies
325 to platforms where the C double format is not IEEE 754 binary64, and
326 to platforms on x86 hardware where the x87 FPU is set to 64-bit
327 precision and Python's configure script is unable to determine how
328 to change the FPU precision. On these platforms conversions use the
329 platform strtod and dtoa, as before.

Mark Dickinsonbd15a062009-11-18 19:33:35 +0000331- Issue #7117: Backport round implementation from Python 3.x. round
Mark Dickinsonb678de82009-11-19 18:41:49 +0000332 now uses the correctly-rounded string <-> float conversions
333 described above (when available), and so produces correctly rounded
334 results that will display nicely under the float repr. There are
335 two related small changes: (1) round now accepts any class with an
336 __index__ method for its second argument (but no longer accepts
Mark Dickinsonbd15a062009-11-18 19:33:35 +0000337 floats for the second argument), and (2) an excessively large second
338 integer argument (e.g., round(1.234, 10**100)) no longer raises an
339 exception.

617
Antoine Pitrouc2f02212009-01-13 23:13:52 +0000618- Issue #4935: The overflow checking code in the expandtabs() method common
619 to str, bytes and bytearray could be optimized away by the compiler, letting
620 the interpreter segfault instead of raising an error.
621
Amaury Forgeot d'Arca40d5732009-01-12 23:36:55 +0000622- Issue #3720: Fix a crash when an iterator modifies its class and removes its

628
Antoine Pitrou4c5ecb72009-01-09 21:40:55 +0000629- Issue #4074: Change the criteria for doing a full garbage collection (i.e.
630 collecting the oldest generation) so that allocating lots of objects without
631 destroying them does not show quadratic performance. Based on a proposal by
Benjamin Petersond50a5d52009-07-13 00:03:20 +0000632 Martin von Löwis at

636
Antoine Pitroue96d4ea2009-01-06 18:10:47 +0000637- Issue #1180193: When importing a module from a .pyc (or .pyo) file with
638 an existing .py counterpart, override the co_filename attributes of all
639 code objects if the original filename is obsolete (which can happen if the
640 file has been renamed, moved, or if it is accessed through different paths).
641 Patch by Ziga Seilnacht and Jean-Paul Calderone.
642
Martin v. Löwis5344c992009-01-02 20:32:55 +0000643- Issue #4075: Use OutputDebugStringW in Py_FatalError.

Hirokazu Yamamoto99a1b202009-01-01 15:45:39 +0000645- Issue #4797: IOError.filename was not set when _fileio.FileIO failed to open
646 file with `str' filename on Windows.
647
Antoine Pitrouaa687902009-01-01 14:11:22 +0000648- Issue #3680: Reference cycles created through a dict, set or deque iterator

650
Nick Coghlan180e4002008-12-30 01:18:48 +0000651- Issue #4701: PyObject_Hash now implicitly calls PyType_Ready on types

653
Benjamin Peterson7af65562008-12-29 17:56:58 +0000654- Issue #4764: With io.open, IOError.filename is set when trying to open a

662
Skip Montanarof205c132008-12-23 03:30:15 +0000663- Added test case to ensure attempts to read from a file opened for writing

677
Jeffrey Yasskinffd42cf2008-12-10 07:35:02 +0000678- Issue #4597: Fixed several opcodes that weren't always propagating
679 exceptions.
680
Mark Dickinson826f3fe2008-12-05 21:55:28 +0000681- Issue #4445: Replace "sizeof(PyStringObject)" with
682 "offsetof(PyStringObject, ob_sval) + 1" when allocating memory for
683 str instances. On a typical machine this saves 3 bytes of memory
684 (on average) per string allocation.
685
Amaury Forgeot d'Arcdc619012008-11-22 20:01:18 +0000686- Issue #3996: On Windows, the PyOS_CheckStack function would cause the
687 interpreter to abort ("Fatal Python error: Could not reset the stack!")
688 instead of throwing a MemoryError.
689
Raymond Hettinger7989a4d2008-12-03 15:42:10 +0000690- Issue #3689: The list reversed iterator now supports __length_hint__
691 instead of __len__. Behavior now matches other reversed iterators.
692
Benjamin Petersonc078f922008-11-21 22:27:24 +0000693- Issue #4367: Python would segfault during compiling when the unicodedata
694 module couldn't be imported and \N escapes were present.
695
Vinay Sajip213faca2008-12-03 23:22:58 +0000696- Issue #4233: Changed semantic of ``_fileio.FileIO``'s ``close()``
Amaury Forgeot d'Arc32265652008-11-20 23:34:31 +0000697 method on file objects with closefd=False. The file descriptor is still
698 kept open but the file object behaves like a closed file. The ``FileIO``
699 object also got a new readonly attribute ``closefd``.
700
Benjamin Peterson46cc6d12008-11-19 21:49:09 +0000701- Issue #4348: Some bytearray methods returned that didn't cause any change to
702 the bytearray, returned the same bytearray instead of a copy.
703
Amaury Forgeot d'Arc7cfe7ea2008-11-18 22:19:37 +0000704- Issue #4317: Fixed a crash in the imageop.rgb2rgb8() function.
705

707
Benjamin Peterson6624a9f2008-11-03 15:14:51 +0000708- Issue #4048: The parser module now correctly validates relative imports.
709
Benjamin Petersondcee09d2008-10-31 02:16:05 +0000710- Issue #4225: ``from __future__ import unicode_literals`` didn't work in an

712
Amaury Forgeot d'Arc69a9c5b2008-10-30 21:18:34 +0000713- Issue #4176: Fixed a crash when pickling an object which ``__reduce__``
714 method does not return iterators for the 4th and 5th items.
715
Benjamin Petersonbdca9422008-10-26 20:21:13 +0000716- Issue #4209: Enabling unicode_literals and the print_function in the same
717 __future__ import didn't work.
718
Benjamin Peterson399b1fe2008-10-25 02:53:28 +0000719- Using ``nonlocal`` as a variable name will now raise a Py3k SyntaxWarning
Georg Brandl7fb00ad2008-10-25 07:00:52 +0000720 because it is a reserved word in 3.x.
Benjamin Peterson399b1fe2008-10-25 02:53:28 +0000721
Hirokazu Yamamoto10a018c2008-10-09 10:00:30 +0000722- On windows, os.chdir given unicode was not working if GetCurrentDirectoryW
723 returned a path longer than MAX_PATH. (But It's doubtful this code path is
724 really executed because I cannot move to such directory on win2k)
725
Amaury Forgeot d'Arcd78b9dc2008-10-07 20:32:10 +0000726- Issue #4069: When set.remove(element) is used with a set element, the element
727 is temporarily replaced with an equivalent frozenset. But the eventual
728 KeyError would always report the empty frozenset([]) as the missing key. Now
729 it correctly refers to the initial element.
730
Antoine Pitrouae5bece2008-12-06 21:29:24 +0000731- Issue #4509: Various issues surrounding resize of bytearray objects to
732 which there are buffer exports.

742
Matthias Klose91a3b9e2009-04-05 21:19:13 +0000743- Issue #1113244: Py_XINCREF, Py_DECREF, Py_XDECREF: Add `do { ... } while (0)'
744 to avoid compiler warnings.

Gregory P. Smith2b3eb372009-04-05 23:48:26 +0000746- Issue #5705: os.setuid() would not accept values > 2**31-1 but pwd.getpwnam()
747 returned them on 64bit platforms.
748
Walter Dörwalded960ac2009-05-03 22:36:33 +0000749- Issue #5108: Handle %s like %S and %R in PyUnicode_FromFormatV(): Call
750 PyUnicode_DecodeUTF8() once, remember the result and output it in a second
751 step. This avoids problems with counting UTF-8 bytes that ignores the effect
752 of using the replace error handler in PyUnicode_DecodeUTF8().
753
Walter Dörwald726ba8e2009-05-06 14:32:35 +0000754- Issue #3739: The unicode-internal encoder now reports the number of characters
755 consumed like any other encoder (instead of the number of bytes).
756
Benjamin Peterson91c12eb2009-12-03 02:52:39 +0000757- Issue #2422: When compiled with the ``--with-valgrind`` option, the
758 pymalloc allocator will be automatically disabled when running under
759 Valgrind. This gives improved memory leak detection when running
760 under Valgrind, while taking advantage of pymalloc at other times.

2141
Amaury Forgeot d'Arc05e34492008-09-10 22:04:45 +00002142- Issue #3743: In a few places, PY_FORMAT_SIZE_T was incorrectly used with
2143 PyString_FromFormat or PyErr_Format to display size_t values. The macro
2144 PY_FORMAT_SIZE_T is designed to select the correct format for the OS
2145 ``printf`` function, whereas PyString_FromFormat has an independent
2146 implementation and uses "%zd" on all platforms for size_t values.
2147 This makes a difference on win64, where ``printf`` needs "%Id" to display
2148 64bit values.

Benjamin Peterson97179b02008-09-09 20:55:01 +00002150- Issue #3634: _weakref.ref(Exception).__init__() gave invalid return value on

2154 object; previously an int would be returned for small values. the __long__
2155 method is allowed to return either an int or a long, but the behaviour of

Vinay Sajip35e3b032008-09-01 14:33:59 +00002164 PyArg_ParseTuple and friends, which occurred when the argument for "s*"
Antoine Pitroud4ae97b2008-08-29 18:39:48 +00002165 was correctly parsed but parsing of subsequent arguments failed.
2166
Vinay Sajip35e3b032008-09-01 14:33:59 +00002167- Issue #2534: speed up isinstance() and issubclass() by 50-70%, so as to
Antoine Pitrou0668c622008-08-26 22:42:08 +00002168 match Python 2.5 speed despite the __instancecheck__ / __subclasscheck__
2169 mechanism. In the process, fix a bug where isinstance() and issubclass(),
2170 when given a tuple of classes as second argument, were looking up
2171 __instancecheck__ / __subclasscheck__ on the tuple rather than on each
2172 type object.

2290 wrapper for warnings.catch_warnings() that makes it easier to check
2291 that expected warning messages are being reported.

Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00002311What's New in Python 2.6 beta 3?
2312================================
2313
Barry Warsaw07a4a382008-08-21 01:15:08 +00002314*Release date: 20-Aug-2008*
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00002315
2316Core and Builtins
2317-----------------
2318
Guido van Rossumf8402962008-08-20 15:01:50 +00002319- Issue #1878: Remove Py_TPFLAGS_HAVE_VERSION_TAG from
2320 Py_TPFLAGS_DEFAULT when not building the core. This means 3rd party
2321 extensions do not automatically benefit from the class attribute
2322 cache; they will have to explicitly add Py_TPFLAGS_HAVE_VERSION_TAG
2323 to their tp_flags field if they care. This is a backwards
2324 compatibility feature; in 3.0, all types will use the cache by
2325 default.
2326
Benjamin Petersonf647dc12008-08-20 01:27:30 +00002327- Keyword arguments can now follow starred arguments. (``f(a, *args,
2328 keyword=23)`` is now valid syntax.)
2329
Thomas Heller0ad5ae02008-08-19 19:25:04 +00002330- ctypes function pointers that are COM methods have a boolean True
2331 value again.
2332
Martin v. Löwisf91d46a2008-08-12 14:49:50 +00002333- Issue #3139: Make buffer-interface thread-safe wrt. PyArg_ParseTuple,
2334 by denying s# to parse objects that have a releasebuffer procedure,
2335 and introducing s*.
2336
Georg Brandl1e13ea92008-08-11 09:07:59 +00002337- Issue #3537: Fix an assertion failure when an empty but presized dict
2338 object was stored in the freelist.
2339
Mark Dickinsonb6467572008-08-04 21:30:09 +00002340- Issue #1481296: Make long(float('nan')) and int(float('nan')) raise
2341 ValueError consistently across platforms.
2342
Amaury Forgeot d'Arc39fd6722008-07-31 21:28:03 +00002343- Issue #3479: On platforms where sizeof(int) is smaller than sizeof(long)
2344 (64bit Unix, for example), unichr() would truncate its argument and return
2345 u'\x00' for unichr(2**32). Now it properly raises an OverflowError.
2346
Neal Norwitze7d8be82008-07-31 17:17:14 +00002347- Apply security patches from Apple.
2348
Amaury Forgeot d'Arc246daed2008-07-31 00:42:16 +00002349- Issue #2542: Now that issubclass() may call arbitrary code, ensure that
2350 PyErr_ExceptionMatches returns 0 when an exception occurs there.
2351
Antoine Pitrou92f82162008-07-25 22:22:08 +00002352- Issue #1819: function calls with several named parameters are now on
2353 average 35% faster (as measured by pybench).
2354
Amaury Forgeot d'Arce4921fe2008-07-21 22:00:38 +00002355- Issue #2378: An unexpected UnboundLocalError or NameError could appear when
2356 the python debugger steps into a class statement: the free variables (local
2357 variables defined in an outer scope) would be deleted from the outer scope.
2358
Gregory P. Smith0470bab2008-07-22 04:46:32 +00002359- Issue #2620: Overflow checking when allocating or reallocating memory
2360 was not always being done properly in some python types and extension
2361 modules. PyMem_MALLOC, PyMem_REALLOC, PyMem_NEW and PyMem_RESIZE have
2362 all been updated to perform better checks and places in the code that
2363 would previously leak memory on the error path when such an allocation
2364 failed have been fixed.
2365
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00002366Library
2367-------
2368
Hirokazu Yamamoto838c79f2008-08-20 13:14:07 +00002369- Issue #3612: Added some missing basic types in ctypes.wintypes.
2370
Benjamin Petersone977ad42008-08-20 01:42:01 +00002371- The methods ``is_in_tuple()``, ``is_vararg()``, and ``is_keywordarg()`` of
2372 symtable.Symbol have been deprecated for removal in 3.0 and the next release.
2373
Amaury Forgeot d'Arc351ffb82008-08-18 19:23:47 +00002374- Issue #2234: distutils failed for some versions of the cygwin compiler. The
2375 version reported by these tools does not necessarily follow the python
2376 version numbering scheme, so the module is less strict when parsing it.
2377
Nick Coghlanf70385a2008-08-18 12:42:46 +00002378- Issue #2235: Added Py3k warnings for types which will become unhashable
2379 under the stricter __hash__ inheritance rules in 3.0. Several types
2380 which did not meet the rules for hash invariants and were already
2381 unhashable in 3.0 have now been explicitly flagged as unhashable in
2382 2.6 as well (collections.Mapping, collections.Set, unittest.TestSuite,
2383 xml.dom.minidom.NamedNodeMap, numbers.Number, UserList.UserList)
2384
Brett Cannon88f801d2008-08-18 00:46:22 +00002385- Update __all__ for cookielib, csv, os, urllib2, and weakref to include things
2386 imported into the module but exposed as part of the module's API.
2387
Brett Cannon7b96f072008-08-18 00:41:11 +00002388- Remove an unneeded import of abc.ABCMeta from 'inspect'.
2389
Brett Cannon46225e72008-08-18 00:36:52 +00002390- Remove unneeded imports of 'sys' and 'warnings' from 'io'.
2391
Brett Cannon25c9d6a2008-08-17 22:10:11 +00002392- Remove unneeded imports of 'warnings' from shelve, filecmp, and dummy_thread.
2393
Hirokazu Yamamoto41a81eb2008-08-17 13:10:46 +00002394- Issue #3575: Incremental decoder's decode function now takes bytearray
2395 by using 's*' instead of 't#'.
2396
Mark Dickinson3e4caeb2009-02-21 20:27:01 +00002397- Issue #2222: Fixed reference leak when occurred os.rename()
Hirokazu Yamamoto7f30a682008-08-17 09:46:56 +00002398 fails unicode conversion on 2nd parameter. (windows only)
2399
Facundo Batista94f243a2008-08-17 03:38:39 +00002400- Issue 2464. urllib2 now supports a malformation in the URL received
2401 in a redirect.
2402
Brett Cannonabe423e2008-08-16 21:47:07 +00002403- Silence the DeprecationWarning raised when importing mimetools in
Brett Cannon721b1452008-08-16 22:00:27 +00002404 BaseHTTPServer, cgi (and rfc822), httplib.
Brett Cannonabe423e2008-08-16 21:47:07 +00002405
Facundo Batistaeb90b782008-08-16 14:44:07 +00002406- Issue #2776: fixed small issue when handling an URL with double slash
2407 after a 302 response in the case of not going through a proxy.
2408
Antoine Pitroub90a8be2008-08-15 21:03:21 +00002409- Issue #2676: in the email package, content-type parsing was hanging on
2410 pathological input because of quadratic or exponential behaviour of a
2411 regular expression.
2412
Antoine Pitrou11ec65d2008-08-14 21:04:30 +00002413- Issue #3476: binary buffered reading through the new "io" library is now
2414 thread-safe.
2415
Brett Cannonbf3157b2008-08-14 05:00:03 +00002416- Silence the DeprecationWarning of rfc822 when it is imported by mimetools
2417 since mimetools itself is deprecated. Because modules are cached, all
2418 subsequent imports of rfc822 will not raise a visible DeprecationWarning.
2419
Antoine Pitrou9fcd4b32008-08-11 17:21:36 +00002420- Issue #3134: shutil referenced undefined WindowsError symbol.
2421
Robert Schuppenies14646332008-08-10 11:01:53 +00002422- Issue #1342811: Fix leak in Tkinter.Menu.delete. Commands associated to
2423 menu entries were not deleted.
2424
Brett Cannon83e81842008-08-09 23:30:55 +00002425- Copied the implementation of reduce() to _functools.reduce() to have a
2426 version that did not raise a DeprecationWarning under -3.
2427
Antoine Pitrou76b8bee2008-08-09 17:27:23 +00002428- Issue #3205: When iterating over a BZ2File fails allocating memory, raise
2429 a MemoryError rather than silently stop the iteration.
2430
Guido van Rossum59ce9012008-08-09 14:55:34 +00002431- Issue #3487: sre "bytecode" validator. Passing invalid "re-bytecode"
2432 to _sre.compile() will now be rejected. This should not affect anybody
2433 since the re.compile() function never generates invalid re-bytecode.
2434
Skip Montanaroa032bf42008-08-08 22:52:51 +00002435- Issue #3436: Make csv.DictReader's fieldnames attribute a property so that
2436 upon first access it can be automatically initialized from the csv file if
2437 it wasn't initialized during instantiation.
2438
Brett Cannon3aa2a492008-08-06 22:28:09 +00002439- Issue #2338: Create imp.reload() to help with transitioning to Python 3.0 as
2440 the reload() built-in has been removed.
2441
Brett Cannon7e30b672008-08-04 21:52:25 +00002442- Changed code in the following modules/packages to remove warnings raised
Brett Cannonc1b76e42008-08-09 23:06:16 +00002443 while running under the ``-3`` flag: aifc, asynchat, asyncore, bdb, bsddb,

Lars Gustäbel727bd0b2008-08-02 11:26:39 +00002450- Issue #3039: Fix tarfile.TarFileCompat.writestr() which always
2451 raised an AttributeError.
2452
Benjamin Peterson01a24322008-07-28 23:35:27 +00002453- Issue #2523: Fix quadratic behaviour when read()ing a binary file without
Antoine Pitroude781a42008-08-09 12:43:23 +00002454 asking for a specific length. This problem only affected files opened
2455 using the new "io" module, not the built-in open() function.
Benjamin Peterson01a24322008-07-28 23:35:27 +00002456
Mark Dickinsonfe84cce2008-07-27 06:39:07 +00002457- Issue #3449: Update decimal module to use most recent specification
2458 (v. 1.68) and tests (v. 2.58) from IBM.
2459
Skip Montanarof9ac43f2008-07-27 00:50:41 +00002460- Issue 3437: Bug fix in robotparser parsing of Allow: lines.

2468
2469- Issue #3303: Fix a crash in locale.strcoll() when calling it with
2470 invalid arguments.
2471
2472- Issue #3302: Fix several crashes when calling locale's gettext functions
2473 with None arguments.
2474
2475- Issue #3389: Allow resolving dotted names for handlers in logging
2476 configuration files.
2477
2478- Deprecate the sunaudio module for removal in Python 3.0.
2479
Antoine Pitrou5fdfa3e2008-07-25 19:42:26 +00002480- Issue #3394: zipfile.writestr sets external attributes when passed a
2481 file name rather than a ZipInfo instance, so files are extracted with
2482 mode 0600 rather than 000 under Unix.
2483
Gregory P. Smitha36f8fe2008-08-04 00:13:29 +00002484- Issue #1857: subprocess.Popen.poll gained an additional _deadstate keyword
2485 argument in python 2.5, this broke code that subclassed Popen to include its
2486 own poll method. Fixed my moving _deadstate to an _internal_poll method.

Nick Coghlan6e8fef02008-08-18 13:14:22 +00002496- Issue #2235: the C API function PyObject_HashNotImplemented and its
2497 interaction with the tp_hash slot (added in 2.6b2) are now documented
2498
Nick Coghlan2a0c2b12008-08-04 12:47:17 +00002499- Issue #643841: The language reference now provides more detailed
2500 coverage of the lookup process for special methods. The disclaimers
2501 regarding lack of coverage of new-style classes have also been
2502 removed, since the coverage is now fairly reasonable.

2507
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00002508*Release date: 17-Jul-2008*

2511-----------------
2512
Georg Brandl3e483f62008-07-16 22:57:41 +00002513- Issue #3156: Fix inconsistent behavior of the bytearray type: all
2514 its methods now allow for items objects that can be converted to
2515 an integer using operator.index().
2516
Mark Dickinson64b7e502008-07-16 09:40:03 +00002517- Issue #3360: Fix incorrect parsing of '020000000000.0', which
2518 produced a ValueError instead of giving the correct float.
2519
Eric Smitha5fa5a22008-07-16 00:11:49 +00002520- Issue #3083: Add alternate (#) formatting for bin, oct, hex output
2521 for str.format(). This adds the prefix 0b, 0o, or 0x, respectively.
2522
Mark Dickinson7103aa42008-07-15 19:08:33 +00002523- Issue #3008: the float type has a new instance method 'float.hex'
2524 and a new class method 'float.fromhex' to convert floating-point
2525 numbers to and from hexadecimal strings, respectively.
2526
Nick Coghlan6d6bd442008-07-15 15:40:22 +00002527- Issue #2235: __hash__ is once again inherited by default. To allow
2528 collections.Hashable to remain meaningful in the presence of the
2529 default hash implementation (object.__hash__), it is now possible
2530 to explicit block inheritance of hash by setting __hash__=None at
2531 the Python level, or tp_hash=PyObject_HashNotImplemented at the C
2532 level.
2533
Nick Coghlanb028f502008-07-13 14:52:36 +00002534- Issue #3221: Issue a RuntimeWarning instead of raising SystemError if
2535 the parent module cannot be found while performing an absolute import.
2536 This means that an incorrectly defined __package__ attribute will
2537 now only prevent relative imports in that module rather than causing
2538 all imports from that module to fail.
2539
Nick Coghlan14ff9942008-07-08 14:21:42 +00002540- Issue #2517: Allow unicode messages in Exceptions again by correctly
2541 bypassing the instance dictionary when looking up __unicode__ on
2542 new-style classes.
2543
Amaury Forgeot d'Arcbdd941f2008-07-01 20:38:04 +00002544- Issue #3242: Fix a crash inside the print statement, if sys.stdout is
2545 set to a custom object whose write() method happens to install
2546 another file in sys.stdout.

2550 another thread's dictionary.
2551
Mark Dickinson1ec2fcd2008-06-20 14:53:43 +00002552- Issue #3004: Minor change to slice.indices(): the start and stop
2553 arguments are now treated identically, making the behaviour easier
2554 to describe and understand. For example, slice(None, -10,
2555 1).indices(9) now returns (0, 0, 1) instead of (0, -1, 1), and
2556 slice(None, 10, -1).indices(10) returns (9, 9, -1) instead of (9,
2557 10, -1).
2558
Georg Brandl278fc502008-07-19 12:46:12 +00002559- Issue #3219: Calling a function with repeated keyword arguments,

2561 from 2.4 caused by the switch to the new compiler.

Georg Brandl5cc774e2008-06-11 20:28:06 +00003011 PPC64 and x86_64 support in one binary).
Ronald Oussoren5640ce22008-06-05 12:58:24 +00003012
3013 This is controlled by the configure argument ``--with-universal-archs``:

3016
3017 - ``--with-universal-archs=32-bit``: install 2-way universal, 32-bit (the default)
3018

3060 two handlers that derive the same default base class.

Georg Brandl3ee81df2008-05-17 18:14:43 +00003073- Issue #1631171: Re-implement the 'warnings' module in C (the
3074 original Python code has been kept as backup). This will allow for
3075 using the 'warning's machinery in such places as the parser where
3076 use of pure Python code is not possible. Both the ``showarning()``
3077 and ``formatwarning()`` gain an optional 'line' argument which is
3078 not called by default for backwards-compatibility reasons. Setting
3079 ``warnings.showwarning()`` to an implementation that lacks support
3080 for the ``line`` argument will raise a DeprecationWarning.

Georg Brandl3ee81df2008-05-17 18:14:43 +00003143- Issue #2550: The approach used by client/server code for obtaining
3144 ports to listen on in network-oriented tests has been refined in an
3145 effort to facilitate running multiple instances of the entire
3146 regression test suite in parallel without issue.
3147 test_support.bind_port() has been fixed such that it will always
3148 return a unique port -- which wasn't always the case with the
3149 previous implementation, especially if socket options had been set
3150 that affected address reuse (i.e. SO_REUSEADDR, SO_REUSEPORT). The
3151 new implementation of bind_port() will actually raise an exception
3152 if it is passed an AF_INET/SOCK_STREAM socket with either the
3153 SO_REUSEADDR or SO_REUSEPORT socket option set. Furthermore, if
3154 available, bind_port() will set the SO_EXCLUSIVEADDRUSE option on
3155 the socket it's been passed. This currently only applies to
3156 Windows. This option prevents any other sockets from binding to the
3157 host/port we've bound to, thus removing the possibility of the
3158 'non-deterministic' behaviour, as Microsoft puts it, that occurs
3159 when a second SOCK_STREAM socket binds and accepts to a host/port
3160 that's already been bound by another socket. The optional preferred
3161 port parameter to bind_port() has been removed. Under no
3162 circumstances should tests be hard coding ports!
3163
3164 test_support.find_unused_port() has also been introduced, which will
3165 pass a temporary socket object to bind_port() in order to obtain an
3166 unused port. The temporary socket object is then closed and
3167 deleted, and the port is returned. This method should only be used
3168 for obtaining an unused port in order to pass to an external program
3169 (i.e. the -accept [port] argument to openssl's s_server mode) or as
3170 a parameter to a server-oriented class that doesn't give you direct
3171 access to the underlying socket used.
3172
3173 Finally, test_support.HOST has been introduced, which should be used
3174 for the host argument of any relevant socket calls (i.e. bind and
3175 connect).
Trent Nelsone41b0062008-04-08 23:47:30 +00003176
3177 The following tests were updated to following the new conventions:
Georg Brandl3ee81df2008-05-17 18:14:43 +00003178 test_socket, test_smtplib, test_asyncore, test_ssl, test_httplib,
Trent Nelsone41b0062008-04-08 23:47:30 +00003179 test_poplib, test_ftplib, test_telnetlib, test_socketserver,
3180 test_asynchat and test_socket_ssl.
3181
Georg Brandl3ee81df2008-05-17 18:14:43 +00003182 It is now possible for multiple instances of the regression test
3183 suite to run in parallel without issue.

3451
Fred Drakea8ee94b2008-03-01 02:45:07 +00003452- Issue #2051: pyc and pyo files are no longer created with permission
Barry Warsaw52973612008-03-01 02:23:38 +00003453 644. The mode is now inherited from the py file.

Georg Brandlad61bc82008-02-23 15:11:18 +00003455- Issue #2067: file.__exit__() now calls subclasses' close() method.
3456
3457- Patch #1759: Backport of PEP 3129 class decorators.
Christian Heimes5224d282008-02-23 15:01:05 +00003458
Vinay Sajipb7edfc42008-04-02 21:10:23 +00003459- Issue #1881: An internal parser limit has been increased. Also see
Facundo Batistafc2d0102008-02-23 12:01:13 +00003460 issue 215555 for a discussion.
3461
Eric Smitha73fbe72008-02-23 03:09:44 +00003462- Added the future_builtins module, which contains hex() and oct().
3463 These are the PEP 3127 version of these functions, designed to be
3464 compatible with the hex() and oct() builtins from Python 3.0. They
3465 differ slightly in their output formats from the existing, unchanged
3466 Python 2.6 builtins. The expected usage of the future_builtins
3467 module is:
3468 from future_builtins import hex, oct
3469
Eric Smith7ef40bf2008-02-20 23:34:22 +00003470- Issue #1600: Modifed PyOS_ascii_formatd to use at most 2 digit
3471 exponents for exponents with absolute value < 100. Follows C99
3472 standard. This is a change on Windows, which would use 3 digits.
3473 Also, added 'n' to the formats that PyOS_ascii_formatd understands,
3474 so that any alterations it does to the resulting string will be
3475 available in stringlib/formatter.h (for float.__format__).
3476
Eric Smith5a3c1352008-02-19 13:21:56 +00003477- Implemented PEP 3101, Advanced String Formatting. This adds a new
3478 builtin format(); a format() method for str and unicode; a
3479 __format__() method to object, str, unicode, int, long, float, and
3480 datetime; the class string.Formatter; and the C API
3481 PyObject_Format().
3482
Georg Brandl3ee81df2008-05-17 18:14:43 +00003483- Fixed several potential crashes, all caused by specially crafted
3484 __del__ methods exploiting objects in temporarily inconsistent
3485 state.
Amaury Forgeot d'Arc632fad32008-02-16 20:55:24 +00003486
Vinay Sajipb7edfc42008-04-02 21:10:23 +00003487- Issue #2115: Important speedup in setting __slot__ attributes. Also
Georg Brandl3ee81df2008-05-17 18:14:43 +00003488 prevent a possible crash: an Abstract Base Class would try to access
3489 a slot on a registered virtual subclass.
Amaury Forgeot d'Arc60d6c7f2008-02-15 21:22:45 +00003490
Georg Brandl3ee81df2008-05-17 18:14:43 +00003491- Fixed repr() and str() of complex numbers with infinity or nan as
3492 real or imaginary part.
Christian Heimes2f0da532008-02-15 06:57:08 +00003493
Georg Brandl3ee81df2008-05-17 18:14:43 +00003494- Clear all free lists during a gc.collect() of the highest generation
3495 in order to allow pymalloc to free more arenas. Python may give back
3496 memory to the OS earlier.
Christian Heimes3b718a72008-02-14 12:47:33 +00003497
Georg Brandl3ee81df2008-05-17 18:14:43 +00003498- Issue #2045: Fix an infinite recursion triggered when printing a
3499 subclass of collections.defaultdict, if its default_factory is set
3500 to a bound method.
Amaury Forgeot d'Arcb01aa432008-02-08 00:56:02 +00003501
Christian Heimesf75dbef2008-02-08 00:11:31 +00003502- Fixed a minor memory leak in dictobject.c. The content of the free
3503 list was not freed on interpreter shutdown.
3504
Georg Brandl3ee81df2008-05-17 18:14:43 +00003505- Limit free list of method and builtin function objects to 256
3506 entries each.
Christian Heimes6075a822008-02-06 12:44:34 +00003507
Georg Brandl3ee81df2008-05-17 18:14:43 +00003508- Patch #1953: Added ``sys._compact_freelists()`` and the C API
3509 functions ``PyInt_CompactFreeList`` and ``PyFloat_CompactFreeList``
Christian Heimes422051a2008-02-04 18:00:12 +00003510 to compact the internal free lists of pre-allocted ints and floats.
3511
Georg Brandl3ee81df2008-05-17 18:14:43 +00003512- Issue #1983: Fixed return type of fork(), fork1() and forkpty()
3513 calls. Python expected the return type int but the fork familie
3514 returns pi_t.
Christian Heimes951cc0f2008-01-31 23:08:23 +00003515
Georg Brandl3ee81df2008-05-17 18:14:43 +00003516- Issue #1678380: Fix a bug that identifies 0j and -0j when they
3517 appear in the same code unit.
Mark Dickinson105be772008-01-31 22:17:37 +00003518

3526 the internal lookup cache for ref leak tests.
Christian Heimes908caac2008-01-27 23:34:59 +00003527
Georg Brandl3ee81df2008-05-17 18:14:43 +00003528- Patch #1473257: generator objects gain a gi_code attribute. This is
3529 the same object as the func_code attribute of the function that
3530 produced the generator.
Georg Brandl0cdf9a32008-01-26 14:14:20 +00003531
Georg Brandl3ee81df2008-05-17 18:14:43 +00003532- Issue #1920: "while 0" statements were completely removed by the
3533 compiler, even in the presence of an "else" clause, which is
3534 supposed to be run when the condition is false. Now the compiler
3535 correctly emits bytecode for the "else" suite.
Amaury Forgeot d'Arc31eaafe2008-01-24 22:59:25 +00003536
Guido van Rossumeead05f2008-01-24 18:21:02 +00003537- A few crashers fixed: weakref_in_del.py (issue #1377858);
3538 loosing_dict_ref.py (issue #1303614, test67.py);
3539 borrowed_ref_[34].py (not in tracker).
3540
Vinay Sajipd7cf32e2008-01-24 12:43:33 +00003541- Issue #1069410: The "can't load dll" message box on Windows is
Christian Heimesb2302ba2008-01-23 17:15:06 +00003542 suppressed while an extension is loaded by calling SetErrorMode in
3543 dynload_win.c. The error is still reported properly.
3544
Georg Brandl3ee81df2008-05-17 18:14:43 +00003545- Issue #1915: Python compiles with --enable-unicode=no again. However
Christian Heimes082c9b02008-01-23 14:20:50 +00003546 several extension methods and modules do not work without unicode
3547 support.
3548
Georg Brandl26543b12008-01-21 18:36:51 +00003549- Issue #1882: when compiling code from a string, encoding cookies in the
3550 second line of code were not always recognized correctly.
3551
Georg Brandl14404b62008-01-19 19:27:05 +00003552- Issue #1679: "0x" was taken as a valid integer literal.
3553
Georg Brandl6caad7d2008-01-26 14:19:22 +00003554- Issue #1865: ``bytes`` as an alias for ``str`` and b"" as an alias "" were
Christian Heimes288e89a2008-01-18 18:24:07 +00003555 added.
3556
Christian Heimesc94e2b52008-01-14 04:13:37 +00003557- sys.float_info / PyFloat_GetInfo: The floating point information
3558 object was converted from a dict to a specialized structseq object.
3559
Georg Brandl3ee81df2008-05-17 18:14:43 +00003560- Patch #1816: Added sys.flags structseq. It exposes the status of
3561 most command line arguments and PYTHON* environment variables.
Christian Heimesf31b69f2008-01-14 03:42:48 +00003562
Georg Brandl3ee81df2008-05-17 18:14:43 +00003563- Objects/structseq.c: Implemented new structseq representation. The
3564 patch makes structseqs (e.g. the return value of os.stat) more
3565 readable.
Christian Heimes9c201962008-01-14 03:33:52 +00003566
Georg Brandl3ee81df2008-05-17 18:14:43 +00003567- Patch #1700288: added a type attribute cache that caches method

3625 file can now be directly executed by passing their name to the
3626 interpreter. The directory/zipfile is automatically inserted as the
3627 first entry in sys.path.

Georg Brandl3ee81df2008-05-17 18:14:43 +00003629- Issue #1265: Fix a problem with sys.settrace, if the tracing
3630 function uses a generator expression when at the same time the
3631 executed code is closing a paused generator.
Amaury Forgeot d'Arc0d75f092007-11-13 21:54:28 +00003632
Raymond Hettinger1760c8a2007-11-08 02:52:43 +00003633- sets and frozensets now have an isdisjoint() method.
3634
Raymond Hettinger3f8caa32007-10-24 01:28:33 +00003635- optimize the performance of builtin.sum().
3636
Neal Norwitz44f326e2007-10-05 05:29:17 +00003637- Fix warnings found by the new version of the Coverity checker.
3638
Georg Brandl3ee81df2008-05-17 18:14:43 +00003639- The enumerate() builtin function is no longer bounded to sequences
3640 smaller than LONG_MAX. Formerly, it raised an OverflowError. Now,
3641 automatically shifts from ints to longs.
Raymond Hettinger8f669372007-10-03 21:18:11 +00003642
Georg Brandl3ee81df2008-05-17 18:14:43 +00003643- Issue #1686386: Tuple's tp_repr did not take into account the
3644 possibility of having a self-referential tuple, which is possible
3645 from C code. Nor did object's tp_str consider that a type's tp_str
3646 could do something that could lead to an inifinite recursion.
3647 Py_ReprEnter() and Py_EnterRecursiveCall(), respectively, fixed the
3648 issues.
Brett Cannon0b14f242007-09-30 19:45:10 +00003649
Georg Brandl3ee81df2008-05-17 18:14:43 +00003650- Issue #1164: It was possible to trigger deadlock when using the
3651 'print' statement to write to a file since the GIL was not released
3652 as needed. Now PyObject_Print() does the right thing along with
3653 various tp_print implementations of the built-in types and those in
3654 the collections module.
Brett Cannon01531592007-09-17 03:28:34 +00003655
Georg Brandl3ee81df2008-05-17 18:14:43 +00003656- Issue #1147: Exceptions were directly allowing string exceptions in
3657 their throw() method even though string exceptions no longer
3658 allowed.
Brett Cannon4c20bc42007-09-11 21:02:28 +00003659
Georg Brandl3ee81df2008-05-17 18:14:43 +00003660- Issue #1096: Prevent a segfault from getting the repr of a very
3661 deeply nested list by using the recursion counter.
Brett Cannona0c05512007-09-10 21:38:27 +00003662
Brett Cannon1e534b52007-09-07 04:18:30 +00003663- Issue #1202533: Fix infinite recursion calls triggered by calls to
Georg Brandl3ee81df2008-05-17 18:14:43 +00003664 PyObject_Call() never calling back out to Python code to trigger
3665 recursion depth updates/checks. Required the creation of a static
3666 RuntimeError instance in case normalizing an exception put the
3667 recursion check value past its limit. Fixes crashers
3668 infinite_rec_(1|2|4|5).py.
Brett Cannon1e534b52007-09-07 04:18:30 +00003669
Georg Brandl3ee81df2008-05-17 18:14:43 +00003670- Patch #1031213: Decode source line in SyntaxErrors back to its
3671 original source encoding.

3674 with %G.
3675
Georg Brandl3ee81df2008-05-17 18:14:43 +00003676- Prevent expandtabs() on string and unicode objects from causing a
3677 segfault when a large width is passed on 32-bit platforms.
Neal Norwitz7dbd2a32007-06-09 03:36:34 +00003678

Georg Brandl3ee81df2008-05-17 18:14:43 +00003681- Issue #1722485: remove docstrings again when running with -OO.
Georg Brandla5ea6892007-06-01 11:33:33 +00003682
Neal Norwitz0ac60192007-05-27 04:08:54 +00003683- Add new attribute names for function objects. All the func_* become
Georg Brandl3ee81df2008-05-17 18:14:43 +00003684 __*__ attributes. (Some already existed, e.g., __doc__ and
3685 __name__.)
Neal Norwitz0ac60192007-05-27 04:08:54 +00003686
Neal Norwitz8b2bfbc2007-05-23 06:35:32 +00003687- Add -3 option to the interpreter to warn about features that are
3688 deprecated and will be changed/removed in Python 3.0.
3689
Georg Brandl2134e752007-05-21 20:34:16 +00003690- Patch #1686487: you can now pass any mapping after '**' in function
3691 calls.
3692
Collin Winter62903052007-05-18 23:11:24 +00003693- except clauses may now be spelled either "except E, target:" or
Georg Brandl3ee81df2008-05-17 18:14:43 +00003694 "except E as target:". This is to provide forwards compatibility
3695 with Python 3.0.
Collin Winter62903052007-05-18 23:11:24 +00003696
Brett Cannon229cee22007-05-05 01:34:02 +00003697- Deprecate BaseException.message as per PEP 352.
3698
Georg Brandl3ee81df2008-05-17 18:14:43 +00003699- Issue #1303614: don't expose object's __dict__ when the dict is
Armin Rigo9790a272007-05-02 19:23:31 +00003700 inherited from a builtin base.
3701
Vinay Sajip8549ce32007-05-06 17:53:37 +00003702- When __slots__ are set to a unicode string, make it work the same as
Neal Norwitzcbd9ee62007-04-14 05:25:50 +00003703 setting a plain string, ie don't expand to single letter identifiers.
3704
Raymond Hettinger13936692007-04-11 18:40:58 +00003705- Request #1191699: Slices can now be pickled.
3706
Raymond Hettinger4db5fe92007-04-12 04:10:00 +00003707- Request #1193128: str.translate() now allows a None argument for
3708 translations that only remove characters without re-mapping the
3709 remaining characters.
3710
Georg Brandl5cb76c12007-03-21 09:00:39 +00003711- Patch #1682205: a TypeError while unpacking an iterable is no longer
3712 masked by a generic one with the message "unpack non-sequence".
3713
Neal Norwitzaa754b72007-03-21 06:39:48 +00003714- Remove unused file Python/fmod.c.
3715
Guido van Rossum143b5642007-03-23 04:58:42 +00003716- Bug #1683368: The object.__init__() and object.__new__() methods are
3717 now stricter in rejecting excess arguments. The only time when
3718 either allows excess arguments is when it is not overridden and the
3719 other one is. For backwards compatibility, when both are
3720 overridden, it is a deprecation warning (for now; maybe a Py3k
Guido van Rossum234b1ff2007-03-23 19:39:01 +00003721 warning later). Also, type.__init__() insists on the same signature
3722 as supported by type.__new__().
Guido van Rossum143b5642007-03-23 04:58:42 +00003723
Georg Brandl3ee81df2008-05-17 18:14:43 +00003724- Patch #1675423: PyComplex_AsCComplex() now tries to convert an
3725 object to complex using its __complex__() method before falling back
3726 to the __float__() method. Therefore, the functions in the cmath
3727 module now can operate on objects that define a __complex__()
3728 method.
Georg Brandl2b869942007-03-17 16:08:45 +00003729
Georg Brandl3ee81df2008-05-17 18:14:43 +00003730- Patch #1623563: allow __class__ assignment for classes with
3731 __slots__. The old and the new class are still required to have the
3732 same slot names.
Žiga Seilnacht6f2d09c2007-03-16 11:59:38 +00003733
Georg Brandl3ee81df2008-05-17 18:14:43 +00003734- Patch #1642547: Fix an error/crash when encountering syntax errors

Georg Brandl3ee81df2008-05-17 18:14:43 +00003737- Patch #1462488: Python no longer segfaults when
3738 ``object.__reduce_ex__()`` is called with an object that is faking
3739 its type.
Žiga Seilnacht20f43d32007-03-15 11:44:55 +00003740
Georg Brandl3ee81df2008-05-17 18:14:43 +00003741- Patch #1680015: Don't modify __slots__ tuple if it contains an
3742 unicode name.

Georg Brandl5240d742007-03-13 20:46:32 +00003744- Patch #1444529: the builtin compile() now accepts keyword arguments.
3745
Georg Brandl7b9c5552007-03-12 14:30:05 +00003746- Bug #1678647: write a newline after printing an exception in any
3747 case, even when converting the value to a string failed.
3748
Georg Brandl871f1bc2007-03-12 13:17:36 +00003749- The dir() function has been extended to call the __dir__() method on
Georg Brandl3ee81df2008-05-17 18:14:43 +00003750 its argument, if it exists. If not, it will work like before. This
3751 allows customizing the output of dir() in the presence of a
3752 __getattr__().
Georg Brandl871f1bc2007-03-12 13:17:36 +00003753
Collin Winter276887b2007-03-12 16:11:39 +00003754- Patch #922167: Python no longer segfaults when faced with infinitely
3755 self-recursive reload() calls (as reported by bug #742342).
3756
Georg Brandl3ee81df2008-05-17 18:14:43 +00003757- Patch #1675981: remove unreachable code from ``type.__new__()``
3758 method.
Žiga Seilnacht89032082007-03-11 15:54:54 +00003759
Georg Brandl3ee81df2008-05-17 18:14:43 +00003760- Patch #1491866: change the complex() constructor to allow
3761 parthensized forms. This means complex(repr(x)) now works instead of
3762 raising a ValueError.
Collin Wintere38051d2007-03-09 20:33:07 +00003763
Georg Brandlaa2321b2007-03-07 00:40:28 +00003764- Patch #703779: unset __file__ in __main__ after running a file. This
Georg Brandl3ee81df2008-05-17 18:14:43 +00003765 makes the filenames the warning module prints much more sensible
3766 when a PYTHONSTARTUP file is used.
Georg Brandlaa2321b2007-03-07 00:40:28 +00003767
Georg Brandl49aafc92007-03-07 00:34:46 +00003768- Variant of patch #697613: don't exit the interpreter on a SystemExit
3769 exception if the -i command line option or PYTHONINSPECT environment
Georg Brandl3ee81df2008-05-17 18:14:43 +00003770 variable is given, but break into the interactive interpreter just
3771 like on other exceptions or normal program exit.
Georg Brandl49aafc92007-03-07 00:34:46 +00003772
Georg Brandl3ee81df2008-05-17 18:14:43 +00003773- Patch #1638879: don't accept strings with embedded NUL bytes in

Georg Brandl3ee81df2008-05-17 18:14:43 +00003776- Bug #1674503: close the file opened by execfile() in an error
3777 condition.
Georg Brandl098cd692007-03-06 12:17:50 +00003778
Georg Brandl0fca97a2007-03-05 22:28:08 +00003779- Patch #1674228: when assigning a slice (old-style), check for the
3780 sq_ass_slice instead of the sq_slice slot.
3781
Georg Brandl3ee81df2008-05-17 18:14:43 +00003782- When printing an unraisable error, don't print exceptions. before
3783 the name. This duplicates the behavior whening normally printing
3784 exceptions.
Neal Norwitz88516a62007-02-26 22:41:45 +00003785
Georg Brandl3ee81df2008-05-17 18:14:43 +00003786- Bug #1653736: Properly discard third argument to

Georg Brandl3ee81df2008-05-17 18:14:43 +00003792- Bug #1377858: Fix the segfaulting of the interpreter when an object
3793 created a weakref on itself during a __del__ call for new-style
3794 classes (classic classes still have the bug).
Brett Cannonf5bee302007-01-23 23:21:22 +00003795
Martin v. Löwis6c5c5022007-01-23 21:11:47 +00003796- Bug #1579370: Make PyTraceBack_Here use the current thread, not the

Georg Brandl2c1375c2006-10-12 11:27:59 +00003834- Bug #1545497: when given an explicit base, int() did ignore NULs
3835 embedded in the string to convert.
3836
Georg Brandl846f73a2006-10-08 07:11:54 +00003837- Bug #1569998: break inside a try statement (outside a loop) is now
3838 recognized and rejected.

3841
Armin Rigo7ccbca92006-10-04 12:17:45 +00003842- A number of places, including integer negation and absolute value,
3843 were fixed to not rely on undefined behaviour of the C compiler
3844 anymore.
Martin v. Löwis820d6ac2006-10-04 05:47:34 +00003845
Georg Brandl3267d282006-09-30 09:03:42 +00003846- Bug #1566800: make sure that EnvironmentError can be called with any
3847 number of arguments, as was the case in Python 2.4.
3848
Georg Brandl5d59c092006-09-30 08:43:30 +00003849- Patch #1567691: super() and new.instancemethod() now don't accept
Georg Brandl3ee81df2008-05-17 18:14:43 +00003850 keyword arguments any more (previously they accepted them, but
3851 didn't use them).

Georg Brandl3ee81df2008-05-17 18:14:43 +00003853- Fix a bug in the parser's future statement handling that led to
3854 "with" not being recognized as a keyword after, e.g., this
3855 statement: from __future__ import division, with_statement

4412 -- the failure just occurred later, with a more cumbersome
4413 exception.

Georg Brandl3ee81df2008-05-17 18:14:43 +00004694- Issue #829951: In the smtplib module, SMTP.starttls() now complies
4695 with RFC 3207 and forgets any knowledge obtained from the server not
4696 obtained from the TLS negotiation itself. Patch contributed by Bill
4697 Fenner.
Gregory P. Smith2b3ba582008-01-17 08:03:17 +00004698
Georg Brandl3ee81df2008-05-17 18:14:43 +00004699- Issue #1339: The smtplib.SMTP class has been refactored a bit such
Gregory P. Smithbde4ae42008-01-17 08:35:49 +00004700 that the SMTP.starttls() caller no longer needs to call ehlo()
4701 beforehand. SMTP.starttls() now raises an exception of the server
Georg Brandl3ee81df2008-05-17 18:14:43 +00004702 does not claim to support starttls. Adds the
4703 SMTP.ehlo_or_helo_if_needed() method. Patch contributed by Bill
4704 Fenner.

4784 complex, tuple, list, dict, set, and frozenset. Formerly, it would
4785 silently miscode subclasses of those types. Now, it raises a

Raymond Hettinger12e94202007-11-07 01:13:09 +00004787

Georg Brandl3ee81df2008-05-17 18:14:43 +00004802 time so that opening a database previously created with the DB_DUP
4803 or DB_DUPSORT flag set will keep the proper behavior on subsequent
4804 opens. Specifically: dictionary assignment to a DB object will
4805 replace all values for a given key when the database allows
4806 duplicate values. DB users should use DB.put(k, v) when they want
4807 to store duplicates; not DB[k] = v.
Gregory P. Smithec10a4a2007-11-05 02:32:26 +00004808

4814 characters with ASCII value less than 32. Also, it correctly quotes
4815 dots only if they occur on a single line, as opposed to the previous
4816 behavior of quoting dots if they are the second character of any
4817 line.
Georg Brandl4aef7272007-03-13 22:49:43 +00004818

5140-----
5141
Georg Brandl3ee81df2008-05-17 18:14:43 +00005142- Unified naming convention for free lists and their limits. All free
5143 lists in Object/ are named ``free_list``, the counter ``numfree``
5144 and the upper limit is a macro ``PyName_MAXFREELIST`` inside an
5145 #ifndef block.
Christian Heimes5b970ad2008-02-06 13:33:44 +00005146
Georg Brandl3ee81df2008-05-17 18:14:43 +00005147- ``PySet_Add()`` can now modify a newly created frozenset. Similarly
5148 to ``PyTuple_SetItem``, it can be used to populate a brand new
5149 frozenset; but it does not steal a reference to the added item.

5161
Georg Brandl3ee81df2008-05-17 18:14:43 +00005162- Issue #1521: On 64bit platforms, using PyArgs_ParseTuple with the t#
5163 of w# format code incorrectly truncated the length to an int, even
5164 when PY_SSIZE_T_CLEAN is set. The str.decode method used to return
5165 incorrect results with huge strings.
Georg Brandl6caad7d2008-01-26 14:19:22 +00005166
Georg Brandl3ee81df2008-05-17 18:14:43 +00005167- Issue #1629: Renamed Py_Size, Py_Type and Py_Refcnt to Py_SIZE,

5185- Fix some leftovers from the conversion from int to Py_ssize_t
5186 (relevant to strings and sequences of more than 2**31 items).
5187
5188- Make _PyGILState_NoteThreadState() static, it was not used anywhere
5189 outside of pystate.c and should not be necessary.
5190
Georg Brandl3ee81df2008-05-17 18:14:43 +00005191- ``PyImport_Import`` and ``PyImport_ImportModule`` now always do
5192 absolute imports. In earlier versions they might have used relative
5193 imports under some conditions.
Christian Heimes000a0742008-01-03 22:16:32 +00005194
Georg Brandl3ee81df2008-05-17 18:14:43 +00005195- Added case insensitive comparison methods ``PyOS_stricmp(char*,
5196 char*)`` and ``PyOS_strnicmp(char*, char*, Py_ssize_t)``.
Christian Heimes000a0742008-01-03 22:16:32 +00005197
Georg Brandl3ee81df2008-05-17 18:14:43 +00005198- Bug #1542693: remove semi-colon at end of PyImport_ImportModuleEx

5206 requires Windows 2000 or greater. The _WINVER and NTDDI_VERSION
5207 macros are set to Win2k for x86/32bit builds and WinXP for AMD64
5208 builds.
Christian Heimes95d64472008-02-09 19:55:22 +00005209

Georg Brandl3ee81df2008-05-17 18:14:43 +00005223- Removed the macfs module. It had been deprecated since Python 2.5.
5224 This lead to the deprecation of macostools.touched() as it relied
5225 solely on macfs and was a no-op under OS X.
