163Core and Builtins
164-----------------
165

169 changed.
170
Mark Dickinson82791672010-04-06 16:47:55 +0000171- Issue #8259: 1L << (2**31) no longer produces an 'outrageous shift error'
172 on 64-bit machines. The shift count for either left or right shift is
173 permitted to be up to sys.maxsize.
174
Benjamin Peterson4ceeeb02010-04-03 22:48:51 +0000175- Ensure that tokenization of identifiers is not affected by locale.

182 is called with a non-empty format string. This is an effort to
183 future-proof user code. If a derived class does not currently
184 implement __format__ but later adds its own __format__, it would
185 most likely break user code that had supplied a format string. This
186 will be changed to a DeprecationWaring in Python 3.3 and it will be
187 an error in Python 3.4.
188
Antoine Pitroua57df2c2010-03-31 21:32:15 +0000189- Issue #8268: Old-style classes (not just instances) now support weak

Georg Brandlba83f822010-03-14 09:50:54 +0000203 (SIGINT). If an error occurs while importing the site module, the error is
204 printed and Python exits. Initialize the GIL before importing the site
Victor Stinner66644262010-03-10 22:30:19 +0000205 module.
206
Collin Winter001a3952010-03-18 21:54:01 +0000207- Code objects now support weak references.

215 using the new attributes `ssl.OPENSSL_VERSION`, `ssl.OPENSSL_VERSION_INFO`
216 and `ssl.OPENSSL_VERSION_NUMBER`.
217
Benjamin Peterson76a23c12010-04-04 23:23:22 +0000218- Issue #8310: Allow dis to examine new style classes.
219
Mark Dickinson8a950712010-04-03 15:47:46 +0000220- Issue #8257: The Decimal construct now accepts a float instance

227
Raymond Hettingera551f312010-04-04 18:34:45 +0000228- the functools module now has a total_ordering() class decorator
Georg Brandl4fabac52010-04-14 08:53:38 +0000229 to simplify the specification of rich comparisons.
Raymond Hettingera551f312010-04-04 18:34:45 +0000230
Raymond Hettingerbb006cf2010-04-04 21:45:01 +0000231- The functools module also adds cmp_to_key() as a tool to transition
Raymond Hettingera551f312010-04-04 18:34:45 +0000232 old-style comparison functions to new-style key-functions.
233
Mark Dickinson7c63eee2010-04-02 22:27:36 +0000234- Issue #8294: The Fraction constructor now accepts Decimal and float
235 instances directly.
236
Mark Dickinsone096e822010-04-02 10:17:07 +0000237- Issue #7279: Comparisons involving a Decimal signaling NaN now
238 signal InvalidOperation instead of returning False. (Comparisons
Mark Dickinsonf3eeca12010-04-02 10:35:12 +0000239 involving a quiet NaN are unchanged.) Also, Decimal quiet NaNs
240 are now hashable; Decimal signaling NaNs remain unhashable.
Mark Dickinsone096e822010-04-02 10:17:07 +0000241
Mark Dickinson99d80962010-04-02 08:53:22 +0000242- Issue #2531: Comparison operations between floats and Decimal

Barry Warsawf7f2d6f2010-03-31 21:07:16 +0000247- Issue #8233: When run as a script, py_compile.py optionally takes a single
248 argument `-` which tells it to read files to compile from stdin. Each line
249 is read on demand and the named file is compiled immediately. (Original
250 patch by Piotr Ożarowski).
251
252- Issue #3135: Add inspect.getcallargs, which binds arguments to a function
253 like a normal call.
Benjamin Peterson7e213252010-03-30 17:58:13 +0000254
Florent Xicluna58b65662010-03-30 16:29:03 +0000255- Backwards incompatible change: Unicode codepoints line tabulation (0x0B) and
256 form feed (0x0C) are now considered linebreaks, as specified in Unicode
257 Standard Annex #14. See issue #7643.
Florent Xicluna22b24382010-03-30 08:24:06 +0000258 http://www.unicode.org/reports/tr14/
259
Mark Dickinson9588d992010-03-27 11:14:37 +0000260- Comparisons using one of <, <=, >, >= between a complex instance and
261 a Fractions instance now raise TypeError instead of returning
262 True/False. This makes Fraction <=> complex comparisons consistent with
263 int <=> complex, float <=> complex, and complex <=> complex comparisons.
264
Michael Foorde6410c52010-03-29 20:04:23 +0000265- Addition of ``WeakSet`` to the ``weakref`` module.

276 now silenced.
277
Florent Xicluna9e7a4c92010-03-22 16:07:38 +0000278- Issue #7703: ctypes supports both buffer() and memoryview(). The former is
279 deprecated.
280
R. David Murrayc9d1a782010-03-22 15:55:09 +0000281- Issue #7860: platform.uname now reports the correct 'machine' type
282 when Python is running in WOW64 mode on 64 bit Windows.

288 logger names existing at the same time, causing a Unicode error
289 when configuration code attempted to sort the existing loggers.

295 Also, enable the SSL_MODE_AUTO_RETRY flag on SSL sockets, so that blocking
296 reads and writes are always retried by OpenSSL itself.
Antoine Pitrou448da712010-03-21 19:33:38 +0000297

370 produces a DeprecationWarning in this case. (In Python 2.6, the behaviour
371 was inconsistent: __int__ was used for some integer codes but not for others,
372 and the set of integer codes for which it was used differed between native
373 packing and standard packing.)

614 and add the additional members returned in an OSVERSIONINFOEX structure. The
615 new members are service_pack_major, service_pack_minor, suite_mask, and

631 strings,
632 (2) a crash in dtoa.c that occurred in debug builds when parsing certain long
633 numeric strings corresponding to subnormal values,
634 (3) a memory leak for some values large enough to cause overflow, and
635 (4) a number of flaws that could lead to incorrectly rounded results.

Antoine Pitrouf3fa0742010-01-31 22:26:04 +0000670- Issue #6939: Fix file I/O objects in the `io` module to keep the original
Georg Brandlba83f822010-03-14 09:50:54 +0000671 file position when calling `truncate()`. It would previously change the file
672 position to the given argument, which goes against the tradition of
Antoine Pitrouf3fa0742010-01-31 22:26:04 +0000673 ftruncate() and other truncation APIs. Patch by Pascal Chambon.
674
Benjamin Petersone06f7112010-01-28 02:15:02 +0000675- UserDict is now a new-style class.
676
Georg Brandlba83f822010-03-14 09:50:54 +0000677- Issue #7610: Reworked implementation of the internal ``zipfile.ZipExtFile``
678 class used to represent files stored inside an archive. The new
679 implementation is significantly faster and can be wrapped in a
680 ``io.BufferedReader`` object for more speedups. It also solves an issue
681 where interleaved calls to ``read()`` and ``readline()`` give wrong results.
682 Patch by Nir Aides.

690 when the release file is empty.
Benjamin Petersona43f34c2010-01-25 03:31:13 +0000691
Georg Brandlba83f822010-03-14 09:50:54 +0000692- Issue #7748: Since unicode values are supported for some metadata options in
693 Distutils, the DistributionMetadata get_* methods will now return an utf-8
694 encoded string for them. This ensures that the upload and register commands
695 send the correct values to PyPI without any error.

771
Georg Brandlba83f822010-03-14 09:50:54 +0000772- The ``__complex__()`` method is now looked up on the class of instances to
773 make it consistent with other special methods.

777
Mark Dickinson1b34d252010-01-01 17:27:30 +0000778- Issue #5080: A number of functions and methods previously produced a
Georg Brandlba83f822010-03-14 09:50:54 +0000779 DeprecationWarning when passed a float argument where an integer was expected.
780 These functions and methods now raise TypeError instead. The majority of the
781 effects of this change are in the extension modules, but some core functions
782 and methods are affected: notably the 'chr', 'range' and 'xrange' builtins,
783 and many unicode/str methods.

Georg Brandlba83f822010-03-14 09:50:54 +0000966- Issue #7117: ``repr(x)`` for a float x returns a result based on the shortest
967 decimal string that's guaranteed to round back to x under correct rounding
968 (with round-half-to-even rounding mode). Previously it gave a string based on
969 rounding x to 17 decimal digits. repr(x) for a complex number behaves
970 similarly. On platforms where the correctly-rounded strtod and dtoa code is
971 not supported (see below), repr is unchanged.
Mark Dickinsonb678de82009-11-19 18:41:49 +0000972
Georg Brandlba83f822010-03-14 09:50:54 +0000973- Issue #7117: On almost all platforms: float-to-string and string-to-float
974 conversions within Python are now correctly rounded. Places these conversions
975 occur include: str for floats and complex numbers; the float and complex
976 constructors; old-style and new-style numeric formatting; serialization and
977 deserialization of floats and complex numbers using marshal, pickle and json;
978 parsing of float and imaginary literals in Python code; Decimal-to-float
979 conversion.
Mark Dickinsonb678de82009-11-19 18:41:49 +0000980
Georg Brandlba83f822010-03-14 09:50:54 +0000981 The conversions use a Python-adapted version of David Gay's well-known dtoa.c,
982 providing correctly-rounded strtod and dtoa C functions. This code is
983 supported on Windows, and on Unix-like platforms using gcc, icc or suncc as
984 the C compiler. There may be a small number of platforms on which correct
985 operation of this code cannot be guaranteed, so the code is not used: notably,
986 this applies to platforms where the C double format is not IEEE 754 binary64,
987 and to platforms on x86 hardware where the x87 FPU is set to 64-bit precision
988 and Python's configure script is unable to determine how to change the FPU
989 precision. On these platforms conversions use the platform strtod and dtoa,
990 as before.
Mark Dickinsonb678de82009-11-19 18:41:49 +0000991
Georg Brandlba83f822010-03-14 09:50:54 +0000992- Issue #7117: Backport round implementation from Python 3.x. ``round()`` now
993 uses the correctly-rounded string <-> float conversions described above (when
994 available), and so produces correctly rounded results that will display nicely
995 under the float repr. There are two related small changes: (1) round now
996 accepts any class with an ``__index__()`` method for its second argument (but
997 no longer accepts floats for the second argument), and (2) an excessively
998 large second integer argument (e.g., ``round(1.234, 10**100)``) no longer
999 raises an exception.

1148 but with at least one decimal point and with a default precision
1149 of 12. Previously, the behavior the same but with a default precision of 6.
1150 This more closely matches ``str()``, and reduces surprises when adding

1272
Georg Brandlba83f822010-03-14 09:50:54 +00001273- Issue #4935: The overflow checking code in the expandtabs() method common to
1274 str, bytes and bytearray could be optimized away by the compiler, letting the
1275 interpreter segfault instead of raising an error.
Antoine Pitrouc2f02212009-01-13 23:13:52 +00001276
Amaury Forgeot d'Arca40d5732009-01-12 23:36:55 +00001277- Issue #3720: Fix a crash when an iterator modifies its class and removes its

1283
Antoine Pitrou4c5ecb72009-01-09 21:40:55 +00001284- Issue #4074: Change the criteria for doing a full garbage collection (i.e.
1285 collecting the oldest generation) so that allocating lots of objects without
1286 destroying them does not show quadratic performance. Based on a proposal by
Benjamin Petersond50a5d52009-07-13 00:03:20 +00001287 Martin von Löwis at

1291
Georg Brandlba83f822010-03-14 09:50:54 +00001292- Issue #1180193: When importing a module from a .pyc (or .pyo) file with an
1293 existing .py counterpart, override the co_filename attributes of all code
1294 objects if the original filename is obsolete (which can happen if the file has
1295 been renamed, moved, or if it is accessed through different paths). Patch by
1296 Ziga Seilnacht and Jean-Paul Calderone.
Antoine Pitroue96d4ea2009-01-06 18:10:47 +00001297

Hirokazu Yamamoto99a1b202009-01-01 15:45:39 +00001300- Issue #4797: IOError.filename was not set when _fileio.FileIO failed to open
1301 file with `str' filename on Windows.
1302
Antoine Pitrouaa687902009-01-01 14:11:22 +00001303- Issue #3680: Reference cycles created through a dict, set or deque iterator
1304 did not get collected.
1305
Georg Brandlba83f822010-03-14 09:50:54 +00001306- Issue #4701: PyObject_Hash now implicitly calls PyType_Ready on types where
1307 the tp_hash and tp_dict slots are both NULL.
Nick Coghlan180e4002008-12-30 01:18:48 +00001308
Benjamin Peterson7af65562008-12-29 17:56:58 +00001309- Issue #4764: With io.open, IOError.filename is set when trying to open a
1310 directory on POSIX systems.
1311
Benjamin Petersonfe231b02008-12-29 17:47:42 +00001312- Issue #4764: IOError.filename is set when trying to open a directory on POSIX
1313 systems.
1314
Georg Brandl6425a2f2008-12-28 11:54:53 +00001315- Issue #4759: None is now allowed as the first argument of
Georg Brandlba83f822010-03-14 09:50:54 +00001316 ``bytearray.translate()``. It was always allowed for ``bytes.translate()``.
Georg Brandl6425a2f2008-12-28 11:54:53 +00001317
Skip Montanarof205c132008-12-23 03:30:15 +00001318- Added test case to ensure attempts to read from a file opened for writing
1319 fail.
1320
Georg Brandlba83f822010-03-14 09:50:54 +00001321- Issue #2467: gc.DEBUG_STATS reported invalid elapsed times. Also, always print
1322 elapsed times, not only when some objects are uncollectable/unreachable.
1323 Original patch by Neil Schemenauer.
Antoine Pitrou73c0e652008-12-17 22:46:54 +00001324

Georg Brandlba83f822010-03-14 09:50:54 +00001335- Issue #4445: Replace ``sizeof(PyStringObject)`` with
1336 ``offsetof(PyStringObject, ob_sval) + 1`` when allocating memory for str
1337 instances. On a typical machine this saves 3 bytes of memory (on average) per
1338 string allocation.
Mark Dickinson826f3fe2008-12-05 21:55:28 +00001339
Amaury Forgeot d'Arcdc619012008-11-22 20:01:18 +00001340- Issue #3996: On Windows, the PyOS_CheckStack function would cause the
1341 interpreter to abort ("Fatal Python error: Could not reset the stack!")
1342 instead of throwing a MemoryError.
1343
Georg Brandlba83f822010-03-14 09:50:54 +00001344- Issue #3689: The list reversed iterator now supports __length_hint__ instead
1345 of __len__. Behavior now matches other reversed iterators.
Raymond Hettinger7989a4d2008-12-03 15:42:10 +00001346
Benjamin Petersonc078f922008-11-21 22:27:24 +00001347- Issue #4367: Python would segfault during compiling when the unicodedata
1348 module couldn't be imported and \N escapes were present.
1349
Georg Brandlba83f822010-03-14 09:50:54 +00001350- Issue #4233: Changed semantic of ``_fileio.FileIO``'s ``close()`` method on
1351 file objects with closefd=False. The file descriptor is still kept open but
1352 the file object behaves like a closed file. The ``FileIO`` object also got a
1353 new readonly attribute ``closefd``.
Amaury Forgeot d'Arc32265652008-11-20 23:34:31 +00001354
Benjamin Peterson46cc6d12008-11-19 21:49:09 +00001355- Issue #4348: Some bytearray methods returned that didn't cause any change to
1356 the bytearray, returned the same bytearray instead of a copy.
1357
Georg Brandlba83f822010-03-14 09:50:54 +00001358- Issue #4317: Fixed a crash in the ``imageop.rgb2rgb8()`` function.

Benjamin Peterson273c2332008-11-17 22:39:09 +00001360- Issue #4230: If ``__getattr__`` is a descriptor, it now functions correctly.
1361
Benjamin Peterson6624a9f2008-11-03 15:14:51 +00001362- Issue #4048: The parser module now correctly validates relative imports.
1363
Benjamin Petersondcee09d2008-10-31 02:16:05 +00001364- Issue #4225: ``from __future__ import unicode_literals`` didn't work in an
1365 exec statement.
1366
Georg Brandlba83f822010-03-14 09:50:54 +00001367- Issue #4176: Fixed a crash when pickling an object which ``__reduce__`` method
1368 does not return iterators for the 4th and 5th items.
Amaury Forgeot d'Arc69a9c5b2008-10-30 21:18:34 +00001369
Benjamin Petersonbdca9422008-10-26 20:21:13 +00001370- Issue #4209: Enabling unicode_literals and the print_function in the same
1371 __future__ import didn't work.
1372
Benjamin Peterson399b1fe2008-10-25 02:53:28 +00001373- Using ``nonlocal`` as a variable name will now raise a Py3k SyntaxWarning
Georg Brandl7fb00ad2008-10-25 07:00:52 +00001374 because it is a reserved word in 3.x.
Benjamin Peterson399b1fe2008-10-25 02:53:28 +00001375
Georg Brandlba83f822010-03-14 09:50:54 +00001376- On windows, ``os.chdir()`` given unicode was not working if
1377 GetCurrentDirectoryW returned a path longer than MAX_PATH. (But It's doubtful
1378 this code path is really executed because I cannot move to such directory on
1379 win2k)
Hirokazu Yamamoto10a018c2008-10-09 10:00:30 +00001380
Georg Brandlba83f822010-03-14 09:50:54 +00001381- Issue #4069: When ``set.remove(element)`` is used with a set element, the
1382 element is temporarily replaced with an equivalent frozenset. But the
1383 eventual KeyError would always report the empty ``frozenset()`` as the missing
1384 key. Now it correctly refers to the initial element.
Amaury Forgeot d'Arcd78b9dc2008-10-07 20:32:10 +00001385
Georg Brandlba83f822010-03-14 09:50:54 +00001386- Issue #4509: Various issues surrounding resize of bytearray objects to which

1394
Georg Brandlba83f822010-03-14 09:50:54 +00001395- Issue #3845: In PyRun_SimpleFileExFlags avoid invalid memory access with short

Gregory P. Smith2b3eb372009-04-05 23:48:26 +00001401- Issue #5705: os.setuid() would not accept values > 2**31-1 but pwd.getpwnam()
1402 returned them on 64bit platforms.
1403
Walter Dörwalded960ac2009-05-03 22:36:33 +00001404- Issue #5108: Handle %s like %S and %R in PyUnicode_FromFormatV(): Call
1405 PyUnicode_DecodeUTF8() once, remember the result and output it in a second
1406 step. This avoids problems with counting UTF-8 bytes that ignores the effect
1407 of using the replace error handler in PyUnicode_DecodeUTF8().
1408
Walter Dörwald726ba8e2009-05-06 14:32:35 +00001409- Issue #3739: The unicode-internal encoder now reports the number of characters
1410 consumed like any other encoder (instead of the number of bytes).
1411
Georg Brandlba83f822010-03-14 09:50:54 +00001412- Issue #2422: When compiled with the ``--with-valgrind`` option, the pymalloc
1413 allocator will be automatically disabled when running under Valgrind. This
1414 gives improved memory leak detection when running under Valgrind, while taking
1415 advantage of pymalloc at other times.

2639 threads could return successfully while some Thread objects were still
2640 referenced. This also introduces a new private function: ``thread._count()``.

Georg Brandlba83f822010-03-14 09:50:54 +00002659 the same behaviour as test_ttkguionly (and now also test_tk) which is to skip

2781
Amaury Forgeot d'Arc05e34492008-09-10 22:04:45 +00002782- Issue #3743: In a few places, PY_FORMAT_SIZE_T was incorrectly used with
2783 PyString_FromFormat or PyErr_Format to display size_t values. The macro
2784 PY_FORMAT_SIZE_T is designed to select the correct format for the OS
2785 ``printf`` function, whereas PyString_FromFormat has an independent
2786 implementation and uses "%zd" on all platforms for size_t values.
2787 This makes a difference on win64, where ``printf`` needs "%Id" to display
2788 64bit values.

2794 object; previously an int would be returned for small values. the __long__

Antoine Pitroud4ae97b2008-08-29 18:39:48 +00002805 was correctly parsed but parsing of subsequent arguments failed.

Vinay Sajip35e3b032008-09-01 14:33:59 +00002807- Issue #2534: speed up isinstance() and issubclass() by 50-70%, so as to
Antoine Pitrou0668c622008-08-26 22:42:08 +00002808 match Python 2.5 speed despite the __instancecheck__ / __subclasscheck__
2809 mechanism. In the process, fix a bug where isinstance() and issubclass(),
2810 when given a tuple of classes as second argument, were looking up
2811 __instancecheck__ / __subclasscheck__ on the tuple rather than on each
2812 type object.

Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00002951What's New in Python 2.6 beta 3?
2952================================
2953
Barry Warsaw07a4a382008-08-21 01:15:08 +00002954*Release date: 20-Aug-2008*
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00002955
2956Core and Builtins
2957-----------------
2958
Guido van Rossumf8402962008-08-20 15:01:50 +00002959- Issue #1878: Remove Py_TPFLAGS_HAVE_VERSION_TAG from
2960 Py_TPFLAGS_DEFAULT when not building the core. This means 3rd party
2961 extensions do not automatically benefit from the class attribute
2962 cache; they will have to explicitly add Py_TPFLAGS_HAVE_VERSION_TAG
2963 to their tp_flags field if they care. This is a backwards
2964 compatibility feature; in 3.0, all types will use the cache by
2965 default.
2966
Benjamin Petersonf647dc12008-08-20 01:27:30 +00002967- Keyword arguments can now follow starred arguments. (``f(a, *args,
2968 keyword=23)`` is now valid syntax.)
2969
Thomas Heller0ad5ae02008-08-19 19:25:04 +00002970- ctypes function pointers that are COM methods have a boolean True
2971 value again.
2972
Martin v. Löwisf91d46a2008-08-12 14:49:50 +00002973- Issue #3139: Make buffer-interface thread-safe wrt. PyArg_ParseTuple,
2974 by denying s# to parse objects that have a releasebuffer procedure,
2975 and introducing s*.
2976
Georg Brandl1e13ea92008-08-11 09:07:59 +00002977- Issue #3537: Fix an assertion failure when an empty but presized dict
2978 object was stored in the freelist.
2979
Mark Dickinsonb6467572008-08-04 21:30:09 +00002980- Issue #1481296: Make long(float('nan')) and int(float('nan')) raise
2981 ValueError consistently across platforms.
2982
Amaury Forgeot d'Arc39fd6722008-07-31 21:28:03 +00002983- Issue #3479: On platforms where sizeof(int) is smaller than sizeof(long)
2984 (64bit Unix, for example), unichr() would truncate its argument and return
2985 u'\x00' for unichr(2**32). Now it properly raises an OverflowError.
2986
Neal Norwitze7d8be82008-07-31 17:17:14 +00002987- Apply security patches from Apple.
2988
Amaury Forgeot d'Arc246daed2008-07-31 00:42:16 +00002989- Issue #2542: Now that issubclass() may call arbitrary code, ensure that
2990 PyErr_ExceptionMatches returns 0 when an exception occurs there.
2991
Antoine Pitrou92f82162008-07-25 22:22:08 +00002992- Issue #1819: function calls with several named parameters are now on
2993 average 35% faster (as measured by pybench).
2994
Amaury Forgeot d'Arce4921fe2008-07-21 22:00:38 +00002995- Issue #2378: An unexpected UnboundLocalError or NameError could appear when
2996 the python debugger steps into a class statement: the free variables (local
2997 variables defined in an outer scope) would be deleted from the outer scope.
2998
Gregory P. Smith0470bab2008-07-22 04:46:32 +00002999- Issue #2620: Overflow checking when allocating or reallocating memory
3000 was not always being done properly in some python types and extension
3001 modules. PyMem_MALLOC, PyMem_REALLOC, PyMem_NEW and PyMem_RESIZE have
3002 all been updated to perform better checks and places in the code that
3003 would previously leak memory on the error path when such an allocation
3004 failed have been fixed.
3005
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00003006Library
3007-------
3008
Hirokazu Yamamoto838c79f2008-08-20 13:14:07 +00003009- Issue #3612: Added some missing basic types in ctypes.wintypes.
3010
Benjamin Petersone977ad42008-08-20 01:42:01 +00003011- The methods ``is_in_tuple()``, ``is_vararg()``, and ``is_keywordarg()`` of
3012 symtable.Symbol have been deprecated for removal in 3.0 and the next release.
3013
Amaury Forgeot d'Arc351ffb82008-08-18 19:23:47 +00003014- Issue #2234: distutils failed for some versions of the cygwin compiler. The
3015 version reported by these tools does not necessarily follow the python
3016 version numbering scheme, so the module is less strict when parsing it.
3017
Nick Coghlanf70385a2008-08-18 12:42:46 +00003018- Issue #2235: Added Py3k warnings for types which will become unhashable
3019 under the stricter __hash__ inheritance rules in 3.0. Several types
3020 which did not meet the rules for hash invariants and were already
3021 unhashable in 3.0 have now been explicitly flagged as unhashable in
3022 2.6 as well (collections.Mapping, collections.Set, unittest.TestSuite,
3023 xml.dom.minidom.NamedNodeMap, numbers.Number, UserList.UserList)
3024
Brett Cannon88f801d2008-08-18 00:46:22 +00003025- Update __all__ for cookielib, csv, os, urllib2, and weakref to include things
3026 imported into the module but exposed as part of the module's API.
3027
Brett Cannon7b96f072008-08-18 00:41:11 +00003028- Remove an unneeded import of abc.ABCMeta from 'inspect'.
3029
Brett Cannon46225e72008-08-18 00:36:52 +00003030- Remove unneeded imports of 'sys' and 'warnings' from 'io'.
3031
Brett Cannon25c9d6a2008-08-17 22:10:11 +00003032- Remove unneeded imports of 'warnings' from shelve, filecmp, and dummy_thread.
3033
Hirokazu Yamamoto41a81eb2008-08-17 13:10:46 +00003034- Issue #3575: Incremental decoder's decode function now takes bytearray
3035 by using 's*' instead of 't#'.
3036
Mark Dickinson3e4caeb2009-02-21 20:27:01 +00003037- Issue #2222: Fixed reference leak when occurred os.rename()
Hirokazu Yamamoto7f30a682008-08-17 09:46:56 +00003038 fails unicode conversion on 2nd parameter. (windows only)
3039
Facundo Batista94f243a2008-08-17 03:38:39 +00003040- Issue 2464. urllib2 now supports a malformation in the URL received
3041 in a redirect.
3042
Brett Cannonabe423e2008-08-16 21:47:07 +00003043- Silence the DeprecationWarning raised when importing mimetools in
Brett Cannon721b1452008-08-16 22:00:27 +00003044 BaseHTTPServer, cgi (and rfc822), httplib.
Brett Cannonabe423e2008-08-16 21:47:07 +00003045
Facundo Batistaeb90b782008-08-16 14:44:07 +00003046- Issue #2776: fixed small issue when handling an URL with double slash
3047 after a 302 response in the case of not going through a proxy.
3048
Antoine Pitroub90a8be2008-08-15 21:03:21 +00003049- Issue #2676: in the email package, content-type parsing was hanging on
3050 pathological input because of quadratic or exponential behaviour of a
3051 regular expression.
3052
Antoine Pitrou11ec65d2008-08-14 21:04:30 +00003053- Issue #3476: binary buffered reading through the new "io" library is now
3054 thread-safe.
3055
Brett Cannonbf3157b2008-08-14 05:00:03 +00003056- Silence the DeprecationWarning of rfc822 when it is imported by mimetools
3057 since mimetools itself is deprecated. Because modules are cached, all
3058 subsequent imports of rfc822 will not raise a visible DeprecationWarning.
3059
Antoine Pitrou9fcd4b32008-08-11 17:21:36 +00003060- Issue #3134: shutil referenced undefined WindowsError symbol.
3061
Robert Schuppenies14646332008-08-10 11:01:53 +00003062- Issue #1342811: Fix leak in Tkinter.Menu.delete. Commands associated to
3063 menu entries were not deleted.
3064
Brett Cannon83e81842008-08-09 23:30:55 +00003065- Copied the implementation of reduce() to _functools.reduce() to have a
3066 version that did not raise a DeprecationWarning under -3.
3067
Antoine Pitrou76b8bee2008-08-09 17:27:23 +00003068- Issue #3205: When iterating over a BZ2File fails allocating memory, raise
3069 a MemoryError rather than silently stop the iteration.
3070
Guido van Rossum59ce9012008-08-09 14:55:34 +00003071- Issue #3487: sre "bytecode" validator. Passing invalid "re-bytecode"
3072 to _sre.compile() will now be rejected. This should not affect anybody
3073 since the re.compile() function never generates invalid re-bytecode.
3074
Skip Montanaroa032bf42008-08-08 22:52:51 +00003075- Issue #3436: Make csv.DictReader's fieldnames attribute a property so that
3076 upon first access it can be automatically initialized from the csv file if
3077 it wasn't initialized during instantiation.
3078
Brett Cannon3aa2a492008-08-06 22:28:09 +00003079- Issue #2338: Create imp.reload() to help with transitioning to Python 3.0 as
3080 the reload() built-in has been removed.
3081
Brett Cannon7e30b672008-08-04 21:52:25 +00003082- Changed code in the following modules/packages to remove warnings raised
Brett Cannonc1b76e42008-08-09 23:06:16 +00003083 while running under the ``-3`` flag: aifc, asynchat, asyncore, bdb, bsddb,

3087 subprocess, sqlite3, tarfile, Tkinter, test.test_support, textwrap,
3088 threading, tokenize, traceback, urlparse, wsgiref, xml, xmlrpclib.
Brett Cannon7e30b672008-08-04 21:52:25 +00003089
Lars Gustäbel727bd0b2008-08-02 11:26:39 +00003090- Issue #3039: Fix tarfile.TarFileCompat.writestr() which always
3091 raised an AttributeError.
3092
Benjamin Peterson01a24322008-07-28 23:35:27 +00003093- Issue #2523: Fix quadratic behaviour when read()ing a binary file without
Antoine Pitroude781a42008-08-09 12:43:23 +00003094 asking for a specific length. This problem only affected files opened
3095 using the new "io" module, not the built-in open() function.
Benjamin Peterson01a24322008-07-28 23:35:27 +00003096
Mark Dickinsonfe84cce2008-07-27 06:39:07 +00003097- Issue #3449: Update decimal module to use most recent specification
3098 (v. 1.68) and tests (v. 2.58) from IBM.
3099
Skip Montanarof9ac43f2008-07-27 00:50:41 +00003100- Issue 3437: Bug fix in robotparser parsing of Allow: lines.

3108
3109- Issue #3303: Fix a crash in locale.strcoll() when calling it with
3110 invalid arguments.
3111
3112- Issue #3302: Fix several crashes when calling locale's gettext functions
3113 with None arguments.
3114
3115- Issue #3389: Allow resolving dotted names for handlers in logging
3116 configuration files.
3117
3118- Deprecate the sunaudio module for removal in Python 3.0.
3119
Antoine Pitrou5fdfa3e2008-07-25 19:42:26 +00003120- Issue #3394: zipfile.writestr sets external attributes when passed a
3121 file name rather than a ZipInfo instance, so files are extracted with
3122 mode 0600 rather than 000 under Unix.
3123
Gregory P. Smitha36f8fe2008-08-04 00:13:29 +00003124- Issue #1857: subprocess.Popen.poll gained an additional _deadstate keyword
3125 argument in python 2.5, this broke code that subclassed Popen to include its
3126 own poll method. Fixed my moving _deadstate to an _internal_poll method.

Nick Coghlan6e8fef02008-08-18 13:14:22 +00003136- Issue #2235: the C API function PyObject_HashNotImplemented and its
3137 interaction with the tp_hash slot (added in 2.6b2) are now documented
3138
Nick Coghlan2a0c2b12008-08-04 12:47:17 +00003139- Issue #643841: The language reference now provides more detailed
3140 coverage of the lookup process for special methods. The disclaimers
3141 regarding lack of coverage of new-style classes have also been
3142 removed, since the coverage is now fairly reasonable.

3151-----------------
3152
Georg Brandl3e483f62008-07-16 22:57:41 +00003153- Issue #3156: Fix inconsistent behavior of the bytearray type: all
3154 its methods now allow for items objects that can be converted to
3155 an integer using operator.index().
3156
Mark Dickinson64b7e502008-07-16 09:40:03 +00003157- Issue #3360: Fix incorrect parsing of '020000000000.0', which
3158 produced a ValueError instead of giving the correct float.
3159
Eric Smitha5fa5a22008-07-16 00:11:49 +00003160- Issue #3083: Add alternate (#) formatting for bin, oct, hex output
3161 for str.format(). This adds the prefix 0b, 0o, or 0x, respectively.
3162
Mark Dickinson7103aa42008-07-15 19:08:33 +00003163- Issue #3008: the float type has a new instance method 'float.hex'
3164 and a new class method 'float.fromhex' to convert floating-point
3165 numbers to and from hexadecimal strings, respectively.
3166
Nick Coghlan6d6bd442008-07-15 15:40:22 +00003167- Issue #2235: __hash__ is once again inherited by default. To allow
3168 collections.Hashable to remain meaningful in the presence of the
3169 default hash implementation (object.__hash__), it is now possible
3170 to explicit block inheritance of hash by setting __hash__=None at
3171 the Python level, or tp_hash=PyObject_HashNotImplemented at the C
3172 level.
3173
Nick Coghlanb028f502008-07-13 14:52:36 +00003174- Issue #3221: Issue a RuntimeWarning instead of raising SystemError if
3175 the parent module cannot be found while performing an absolute import.
3176 This means that an incorrectly defined __package__ attribute will
3177 now only prevent relative imports in that module rather than causing
3178 all imports from that module to fail.
3179
Nick Coghlan14ff9942008-07-08 14:21:42 +00003180- Issue #2517: Allow unicode messages in Exceptions again by correctly
3181 bypassing the instance dictionary when looking up __unicode__ on
3182 new-style classes.

3190 another thread's dictionary.
3191
Mark Dickinson1ec2fcd2008-06-20 14:53:43 +00003192- Issue #3004: Minor change to slice.indices(): the start and stop
3193 arguments are now treated identically, making the behaviour easier
3194 to describe and understand. For example, slice(None, -10,
3195 1).indices(9) now returns (0, 0, 1) instead of (0, -1, 1), and
3196 slice(None, 10, -1).indices(10) returns (9, 9, -1) instead of (9,
3197 10, -1).

Georg Brandl5cc774e2008-06-11 20:28:06 +00003651 PPC64 and x86_64 support in one binary).
Ronald Oussoren5640ce22008-06-05 12:58:24 +00003652
3653 This is controlled by the configure argument ``--with-universal-archs``:
3654
3655 - ``--with-universal-archs=all``: install 4-way universal
3656
3657 - ``--with-universal-archs=32-bit``: install 2-way universal, 32-bit (the default)
3658
3659 - ``--with-universal-archs=64-bit``: install 2-way universal, 64-bit
3660
3661 This option should be used in combination with ``--enable-universalsdk=``.

Georg Brandl3ee81df2008-05-17 18:14:43 +00003713- Issue #1631171: Re-implement the 'warnings' module in C (the
3714 original Python code has been kept as backup). This will allow for
3715 using the 'warning's machinery in such places as the parser where
3716 use of pure Python code is not possible. Both the ``showarning()``
3717 and ``formatwarning()`` gain an optional 'line' argument which is
3718 not called by default for backwards-compatibility reasons. Setting
3719 ``warnings.showwarning()`` to an implementation that lacks support
3720 for the ``line`` argument will raise a DeprecationWarning.

Georg Brandl3ee81df2008-05-17 18:14:43 +00003775- Issue #2385: distutils.core.run_script() makes __file__ available,
3776 so the controlled environment will more closely mirror the typical
3777 script environment. This supports setup.py scripts that refer to
3778 data files.

Georg Brandl3ee81df2008-05-17 18:14:43 +00003783- Issue #2550: The approach used by client/server code for obtaining
3784 ports to listen on in network-oriented tests has been refined in an
3785 effort to facilitate running multiple instances of the entire
3786 regression test suite in parallel without issue.
3787 test_support.bind_port() has been fixed such that it will always
3788 return a unique port -- which wasn't always the case with the
3789 previous implementation, especially if socket options had been set
3790 that affected address reuse (i.e. SO_REUSEADDR, SO_REUSEPORT). The
3791 new implementation of bind_port() will actually raise an exception
3792 if it is passed an AF_INET/SOCK_STREAM socket with either the
3793 SO_REUSEADDR or SO_REUSEPORT socket option set. Furthermore, if
3794 available, bind_port() will set the SO_EXCLUSIVEADDRUSE option on
3795 the socket it's been passed. This currently only applies to
3796 Windows. This option prevents any other sockets from binding to the
3797 host/port we've bound to, thus removing the possibility of the
3798 'non-deterministic' behaviour, as Microsoft puts it, that occurs
3799 when a second SOCK_STREAM socket binds and accepts to a host/port
3800 that's already been bound by another socket. The optional preferred
3801 port parameter to bind_port() has been removed. Under no
3802 circumstances should tests be hard coding ports!
3803
3804 test_support.find_unused_port() has also been introduced, which will
3805 pass a temporary socket object to bind_port() in order to obtain an
3806 unused port. The temporary socket object is then closed and
3807 deleted, and the port is returned. This method should only be used
3808 for obtaining an unused port in order to pass to an external program
3809 (i.e. the -accept [port] argument to openssl's s_server mode) or as
3810 a parameter to a server-oriented class that doesn't give you direct
3811 access to the underlying socket used.
3812
3813 Finally, test_support.HOST has been introduced, which should be used
3814 for the host argument of any relevant socket calls (i.e. bind and
3815 connect).
Trent Nelsone41b0062008-04-08 23:47:30 +00003816
3817 The following tests were updated to following the new conventions:
Georg Brandl3ee81df2008-05-17 18:14:43 +00003818 test_socket, test_smtplib, test_asyncore, test_ssl, test_httplib,
Trent Nelsone41b0062008-04-08 23:47:30 +00003819 test_poplib, test_ftplib, test_telnetlib, test_socketserver,
3820 test_asynchat and test_socket_ssl.
3821
Georg Brandl3ee81df2008-05-17 18:14:43 +00003822 It is now possible for multiple instances of the regression test
3823 suite to run in parallel without issue.

4090-----------------
4091
Fred Drakea8ee94b2008-03-01 02:45:07 +00004092- Issue #2051: pyc and pyo files are no longer created with permission
Barry Warsaw52973612008-03-01 02:23:38 +00004093 644. The mode is now inherited from the py file.

Georg Brandlad61bc82008-02-23 15:11:18 +00004095- Issue #2067: file.__exit__() now calls subclasses' close() method.
4096
4097- Patch #1759: Backport of PEP 3129 class decorators.
Christian Heimes5224d282008-02-23 15:01:05 +00004098
Vinay Sajipb7edfc42008-04-02 21:10:23 +00004099- Issue #1881: An internal parser limit has been increased. Also see
Facundo Batistafc2d0102008-02-23 12:01:13 +00004100 issue 215555 for a discussion.
4101
Eric Smitha73fbe72008-02-23 03:09:44 +00004102- Added the future_builtins module, which contains hex() and oct().
4103 These are the PEP 3127 version of these functions, designed to be
4104 compatible with the hex() and oct() builtins from Python 3.0. They
4105 differ slightly in their output formats from the existing, unchanged
4106 Python 2.6 builtins. The expected usage of the future_builtins
4107 module is:
4108 from future_builtins import hex, oct
4109
Eric Smith7ef40bf2008-02-20 23:34:22 +00004110- Issue #1600: Modifed PyOS_ascii_formatd to use at most 2 digit
4111 exponents for exponents with absolute value < 100. Follows C99
4112 standard. This is a change on Windows, which would use 3 digits.
4113 Also, added 'n' to the formats that PyOS_ascii_formatd understands,
4114 so that any alterations it does to the resulting string will be
4115 available in stringlib/formatter.h (for float.__format__).
4116
Eric Smith5a3c1352008-02-19 13:21:56 +00004117- Implemented PEP 3101, Advanced String Formatting. This adds a new
4118 builtin format(); a format() method for str and unicode; a
4119 __format__() method to object, str, unicode, int, long, float, and
4120 datetime; the class string.Formatter; and the C API
4121 PyObject_Format().
4122
Georg Brandl3ee81df2008-05-17 18:14:43 +00004123- Fixed several potential crashes, all caused by specially crafted
4124 __del__ methods exploiting objects in temporarily inconsistent
4125 state.
Amaury Forgeot d'Arc632fad32008-02-16 20:55:24 +00004126
Vinay Sajipb7edfc42008-04-02 21:10:23 +00004127- Issue #2115: Important speedup in setting __slot__ attributes. Also
Georg Brandl3ee81df2008-05-17 18:14:43 +00004128 prevent a possible crash: an Abstract Base Class would try to access
4129 a slot on a registered virtual subclass.
Amaury Forgeot d'Arc60d6c7f2008-02-15 21:22:45 +00004130
Georg Brandl3ee81df2008-05-17 18:14:43 +00004131- Fixed repr() and str() of complex numbers with infinity or nan as
4132 real or imaginary part.
Christian Heimes2f0da532008-02-15 06:57:08 +00004133
Georg Brandl3ee81df2008-05-17 18:14:43 +00004134- Clear all free lists during a gc.collect() of the highest generation
4135 in order to allow pymalloc to free more arenas. Python may give back
4136 memory to the OS earlier.
Christian Heimes3b718a72008-02-14 12:47:33 +00004137
Georg Brandl3ee81df2008-05-17 18:14:43 +00004138- Issue #2045: Fix an infinite recursion triggered when printing a
4139 subclass of collections.defaultdict, if its default_factory is set
4140 to a bound method.
Amaury Forgeot d'Arcb01aa432008-02-08 00:56:02 +00004141
Christian Heimesf75dbef2008-02-08 00:11:31 +00004142- Fixed a minor memory leak in dictobject.c. The content of the free
4143 list was not freed on interpreter shutdown.
4144
Georg Brandl21e99f42010-03-07 15:23:59 +00004145- Limit free list of method and built-in function objects to 256
Georg Brandl3ee81df2008-05-17 18:14:43 +00004146 entries each.
Christian Heimes6075a822008-02-06 12:44:34 +00004147
Georg Brandl3ee81df2008-05-17 18:14:43 +00004148- Patch #1953: Added ``sys._compact_freelists()`` and the C API
4149 functions ``PyInt_CompactFreeList`` and ``PyFloat_CompactFreeList``
Christian Heimes422051a2008-02-04 18:00:12 +00004150 to compact the internal free lists of pre-allocted ints and floats.
4151
Georg Brandl3ee81df2008-05-17 18:14:43 +00004152- Issue #1983: Fixed return type of fork(), fork1() and forkpty()
4153 calls. Python expected the return type int but the fork familie
4154 returns pi_t.
Christian Heimes951cc0f2008-01-31 23:08:23 +00004155
Georg Brandl3ee81df2008-05-17 18:14:43 +00004156- Issue #1678380: Fix a bug that identifies 0j and -0j when they
4157 appear in the same code unit.
Mark Dickinson105be772008-01-31 22:17:37 +00004158
Georg Brandl3ee81df2008-05-17 18:14:43 +00004159- Issue #2025: Add tuple.count() and tuple.index() methods to comply
4160 with the collections.Sequence API.
Raymond Hettinger5b07ebc2008-02-07 00:54:20 +00004161

Georg Brandl3ee81df2008-05-17 18:14:43 +00004165- Added ``PyType_ClearCache()`` and ``sys._clear_type_cache`` to clear
4166 the internal lookup cache for ref leak tests.
Christian Heimes908caac2008-01-27 23:34:59 +00004167
Georg Brandl3ee81df2008-05-17 18:14:43 +00004168- Patch #1473257: generator objects gain a gi_code attribute. This is
4169 the same object as the func_code attribute of the function that
4170 produced the generator.
Georg Brandl0cdf9a32008-01-26 14:14:20 +00004171
Georg Brandl3ee81df2008-05-17 18:14:43 +00004172- Issue #1920: "while 0" statements were completely removed by the
4173 compiler, even in the presence of an "else" clause, which is
4174 supposed to be run when the condition is false. Now the compiler
4175 correctly emits bytecode for the "else" suite.
Amaury Forgeot d'Arc31eaafe2008-01-24 22:59:25 +00004176
Guido van Rossumeead05f2008-01-24 18:21:02 +00004177- A few crashers fixed: weakref_in_del.py (issue #1377858);
4178 loosing_dict_ref.py (issue #1303614, test67.py);
4179 borrowed_ref_[34].py (not in tracker).
4180
Vinay Sajipd7cf32e2008-01-24 12:43:33 +00004181- Issue #1069410: The "can't load dll" message box on Windows is
Christian Heimesb2302ba2008-01-23 17:15:06 +00004182 suppressed while an extension is loaded by calling SetErrorMode in
4183 dynload_win.c. The error is still reported properly.
4184
Georg Brandl3ee81df2008-05-17 18:14:43 +00004185- Issue #1915: Python compiles with --enable-unicode=no again. However
Christian Heimes082c9b02008-01-23 14:20:50 +00004186 several extension methods and modules do not work without unicode
4187 support.
4188
Georg Brandl26543b12008-01-21 18:36:51 +00004189- Issue #1882: when compiling code from a string, encoding cookies in the
4190 second line of code were not always recognized correctly.
4191
Georg Brandl14404b62008-01-19 19:27:05 +00004192- Issue #1679: "0x" was taken as a valid integer literal.
4193
Georg Brandl6caad7d2008-01-26 14:19:22 +00004194- Issue #1865: ``bytes`` as an alias for ``str`` and b"" as an alias "" were
Christian Heimes288e89a2008-01-18 18:24:07 +00004195 added.
4196
Christian Heimesc94e2b52008-01-14 04:13:37 +00004197- sys.float_info / PyFloat_GetInfo: The floating point information
4198 object was converted from a dict to a specialized structseq object.
4199
Georg Brandl3ee81df2008-05-17 18:14:43 +00004200- Patch #1816: Added sys.flags structseq. It exposes the status of
4201 most command line arguments and PYTHON* environment variables.
Christian Heimesf31b69f2008-01-14 03:42:48 +00004202
Georg Brandl3ee81df2008-05-17 18:14:43 +00004203- Objects/structseq.c: Implemented new structseq representation. The
4204 patch makes structseqs (e.g. the return value of os.stat) more
4205 readable.
Christian Heimes9c201962008-01-14 03:33:52 +00004206
Georg Brandl3ee81df2008-05-17 18:14:43 +00004207- Patch #1700288: added a type attribute cache that caches method

4216 envvar and sys.dont_write_bytecode attribute. All these can be set
4217 to forbid Python to attempt to write compiled bytecode files.
Georg Brandl2da0fce2008-01-07 17:09:35 +00004218
Georg Brandl3ee81df2008-05-17 18:14:43 +00004219- Improve some exception messages when Windows fails to load an
4220 extension module. Now we get for example '%1 is not a valid Win32

Georg Brandl3ee81df2008-05-17 18:14:43 +00004229 and INF. float("nan"), float("inf") and float("-inf") now work on
4230 every platform with IEEE 754 semantics.
Christian Heimes0a8143f2007-12-18 23:22:54 +00004231
Georg Brandl3ee81df2008-05-17 18:14:43 +00004232- Compiler now generates simpler and faster code for dictionary
4233 literals. The oparg for BUILD_MAP now indicates an estimated
4234 dictionary size. There is a new opcode, STORE_MAP, for adding
4235 entries to the dictionary.

Georg Brandl21e99f42010-03-07 15:23:59 +00004279- The enumerate() built-in function is no longer bounded to sequences
Georg Brandl3ee81df2008-05-17 18:14:43 +00004280 smaller than LONG_MAX. Formerly, it raised an OverflowError. Now,
4281 automatically shifts from ints to longs.
Raymond Hettinger8f669372007-10-03 21:18:11 +00004282
Georg Brandl3ee81df2008-05-17 18:14:43 +00004283- Issue #1686386: Tuple's tp_repr did not take into account the
4284 possibility of having a self-referential tuple, which is possible
4285 from C code. Nor did object's tp_str consider that a type's tp_str
4286 could do something that could lead to an inifinite recursion.
4287 Py_ReprEnter() and Py_EnterRecursiveCall(), respectively, fixed the
4288 issues.
Brett Cannon0b14f242007-09-30 19:45:10 +00004289
Georg Brandl3ee81df2008-05-17 18:14:43 +00004290- Issue #1164: It was possible to trigger deadlock when using the
4291 'print' statement to write to a file since the GIL was not released
4292 as needed. Now PyObject_Print() does the right thing along with
4293 various tp_print implementations of the built-in types and those in
4294 the collections module.
Brett Cannon01531592007-09-17 03:28:34 +00004295
Georg Brandl3ee81df2008-05-17 18:14:43 +00004296- Issue #1147: Exceptions were directly allowing string exceptions in
4297 their throw() method even though string exceptions no longer
4298 allowed.
Brett Cannon4c20bc42007-09-11 21:02:28 +00004299
Georg Brandl3ee81df2008-05-17 18:14:43 +00004300- Issue #1096: Prevent a segfault from getting the repr of a very
4301 deeply nested list by using the recursion counter.
Brett Cannona0c05512007-09-10 21:38:27 +00004302
Brett Cannon1e534b52007-09-07 04:18:30 +00004303- Issue #1202533: Fix infinite recursion calls triggered by calls to
Georg Brandl3ee81df2008-05-17 18:14:43 +00004304 PyObject_Call() never calling back out to Python code to trigger
4305 recursion depth updates/checks. Required the creation of a static
4306 RuntimeError instance in case normalizing an exception put the
4307 recursion check value past its limit. Fixes crashers
4308 infinite_rec_(1|2|4|5).py.
Brett Cannon1e534b52007-09-07 04:18:30 +00004309
Georg Brandl3ee81df2008-05-17 18:14:43 +00004310- Patch #1031213: Decode source line in SyntaxErrors back to its

Neal Norwitz0ac60192007-05-27 04:08:54 +00004323- Add new attribute names for function objects. All the func_* become
Georg Brandl3ee81df2008-05-17 18:14:43 +00004324 __*__ attributes. (Some already existed, e.g., __doc__ and
4325 __name__.)
Neal Norwitz0ac60192007-05-27 04:08:54 +00004326
Neal Norwitz8b2bfbc2007-05-23 06:35:32 +00004327- Add -3 option to the interpreter to warn about features that are
4328 deprecated and will be changed/removed in Python 3.0.
4329
Georg Brandl2134e752007-05-21 20:34:16 +00004330- Patch #1686487: you can now pass any mapping after '**' in function
4331 calls.
4332
Collin Winter62903052007-05-18 23:11:24 +00004333- except clauses may now be spelled either "except E, target:" or
Georg Brandl3ee81df2008-05-17 18:14:43 +00004334 "except E as target:". This is to provide forwards compatibility
4335 with Python 3.0.
Collin Winter62903052007-05-18 23:11:24 +00004336
Brett Cannon229cee22007-05-05 01:34:02 +00004337- Deprecate BaseException.message as per PEP 352.

Vinay Sajip8549ce32007-05-06 17:53:37 +00004342- When __slots__ are set to a unicode string, make it work the same as
Neal Norwitzcbd9ee62007-04-14 05:25:50 +00004343 setting a plain string, ie don't expand to single letter identifiers.
4344
Raymond Hettinger13936692007-04-11 18:40:58 +00004345- Request #1191699: Slices can now be pickled.
4346
Raymond Hettinger4db5fe92007-04-12 04:10:00 +00004347- Request #1193128: str.translate() now allows a None argument for
4348 translations that only remove characters without re-mapping the
4349 remaining characters.
4350
Georg Brandl5cb76c12007-03-21 09:00:39 +00004351- Patch #1682205: a TypeError while unpacking an iterable is no longer

4353
Neal Norwitzaa754b72007-03-21 06:39:48 +00004354- Remove unused file Python/fmod.c.
4355
Guido van Rossum143b5642007-03-23 04:58:42 +00004356- Bug #1683368: The object.__init__() and object.__new__() methods are
4357 now stricter in rejecting excess arguments. The only time when
4358 either allows excess arguments is when it is not overridden and the
4359 other one is. For backwards compatibility, when both are
4360 overridden, it is a deprecation warning (for now; maybe a Py3k
Guido van Rossum234b1ff2007-03-23 19:39:01 +00004361 warning later). Also, type.__init__() insists on the same signature
4362 as supported by type.__new__().
Guido van Rossum143b5642007-03-23 04:58:42 +00004363
Georg Brandl3ee81df2008-05-17 18:14:43 +00004364- Patch #1675423: PyComplex_AsCComplex() now tries to convert an
4365 object to complex using its __complex__() method before falling back
4366 to the __float__() method. Therefore, the functions in the cmath
4367 module now can operate on objects that define a __complex__()
4368 method.
Georg Brandl2b869942007-03-17 16:08:45 +00004369
Georg Brandl3ee81df2008-05-17 18:14:43 +00004370- Patch #1623563: allow __class__ assignment for classes with
4371 __slots__. The old and the new class are still required to have the
4372 same slot names.

4378 ``object.__reduce_ex__()`` is called with an object that is faking
4379 its type.
Žiga Seilnacht20f43d32007-03-15 11:44:55 +00004380
Georg Brandl3ee81df2008-05-17 18:14:43 +00004381- Patch #1680015: Don't modify __slots__ tuple if it contains an

4385
Georg Brandl7b9c5552007-03-12 14:30:05 +00004386- Bug #1678647: write a newline after printing an exception in any
4387 case, even when converting the value to a string failed.
4388
Georg Brandl871f1bc2007-03-12 13:17:36 +00004389- The dir() function has been extended to call the __dir__() method on
Georg Brandl3ee81df2008-05-17 18:14:43 +00004390 its argument, if it exists. If not, it will work like before. This
4391 allows customizing the output of dir() in the presence of a
4392 __getattr__().

Georg Brandl3ee81df2008-05-17 18:14:43 +00004400- Patch #1491866: change the complex() constructor to allow
4401 parthensized forms. This means complex(repr(x)) now works instead of
4402 raising a ValueError.
Collin Wintere38051d2007-03-09 20:33:07 +00004403
Georg Brandlaa2321b2007-03-07 00:40:28 +00004404- Patch #703779: unset __file__ in __main__ after running a file. This
Georg Brandl3ee81df2008-05-17 18:14:43 +00004405 makes the filenames the warning module prints much more sensible
4406 when a PYTHONSTARTUP file is used.
Georg Brandlaa2321b2007-03-07 00:40:28 +00004407

4409 exception if the -i command line option or PYTHONINSPECT environment
Georg Brandl3ee81df2008-05-17 18:14:43 +00004410 variable is given, but break into the interactive interpreter just
4411 like on other exceptions or normal program exit.

Georg Brandl0fca97a2007-03-05 22:28:08 +00004419- Patch #1674228: when assigning a slice (old-style), check for the
4420 sq_ass_slice instead of the sq_slice slot.
4421
Georg Brandl3ee81df2008-05-17 18:14:43 +00004422- When printing an unraisable error, don't print exceptions. before
4423 the name. This duplicates the behavior whening normally printing
4424 exceptions.

5052 -- the failure just occurred later, with a more cumbersome
5053 exception.

5266 partial fix for Bug #1574584.
5267
Georg Brandl3ee81df2008-05-17 18:14:43 +00005268- Fix turtle so that time.sleep is imported for the entire library.

Georg Brandl3ee81df2008-05-17 18:14:43 +00005334- Issue #829951: In the smtplib module, SMTP.starttls() now complies
5335 with RFC 3207 and forgets any knowledge obtained from the server not
5336 obtained from the TLS negotiation itself. Patch contributed by Bill
5337 Fenner.
Gregory P. Smith2b3ba582008-01-17 08:03:17 +00005338
Georg Brandl3ee81df2008-05-17 18:14:43 +00005339- Issue #1339: The smtplib.SMTP class has been refactored a bit such
Gregory P. Smithbde4ae42008-01-17 08:35:49 +00005340 that the SMTP.starttls() caller no longer needs to call ehlo()
5341 beforehand. SMTP.starttls() now raises an exception of the server
Georg Brandl3ee81df2008-05-17 18:14:43 +00005342 does not claim to support starttls. Adds the
5343 SMTP.ehlo_or_helo_if_needed() method. Patch contributed by Bill
5344 Fenner.

Georg Brandl3ee81df2008-05-17 18:14:43 +00005398- itertools.chain() now has an alternate constructor,

5413 contents before adding elements from the iterable. This fix brings
5414 the behavior into line with that for list.__init__().
Raymond Hettingeradf9ffd2007-12-13 00:08:37 +00005415
Georg Brandl3ee81df2008-05-17 18:14:43 +00005416- Added wide char functions to msvcrt module: getwch, getwche, putwch

5424 complex, tuple, list, dict, set, and frozenset. Formerly, it would
5425 silently miscode subclasses of those types. Now, it raises a
5426 ValueError instead.
Raymond Hettinger12e94202007-11-07 01:13:09 +00005427

Georg Brandl3ee81df2008-05-17 18:14:43 +00005442 time so that opening a database previously created with the DB_DUP
5443 or DB_DUPSORT flag set will keep the proper behavior on subsequent
5444 opens. Specifically: dictionary assignment to a DB object will
5445 replace all values for a given key when the database allows
5446 duplicate values. DB users should use DB.put(k, v) when they want
5447 to store duplicates; not DB[k] = v.
Gregory P. Smithec10a4a2007-11-05 02:32:26 +00005448

5454 characters with ASCII value less than 32. Also, it correctly quotes
5455 dots only if they occur on a single line, as opposed to the previous
5456 behavior of quoting dots if they are the second character of any
5457 line.
Georg Brandl4aef7272007-03-13 22:49:43 +00005458

5780-----
5781
Georg Brandl3ee81df2008-05-17 18:14:43 +00005782- Unified naming convention for free lists and their limits. All free
5783 lists in Object/ are named ``free_list``, the counter ``numfree``
5784 and the upper limit is a macro ``PyName_MAXFREELIST`` inside an
5785 #ifndef block.
Christian Heimes5b970ad2008-02-06 13:33:44 +00005786
Georg Brandl3ee81df2008-05-17 18:14:43 +00005787- ``PySet_Add()`` can now modify a newly created frozenset. Similarly
5788 to ``PyTuple_SetItem``, it can be used to populate a brand new
5789 frozenset; but it does not steal a reference to the added item.
Amaury Forgeot d'Arccab3d982008-02-03 22:51:43 +00005790
Vinay Sajipb7edfc42008-04-02 21:10:23 +00005791- Added ``PySet_Check()`` and ``PyFrozenSet_Check()`` to the set API.

5794 and _FormatV from Python 3.0. Made PyLong_AsSsize_t and
5795 PyLong_FromSsize_t public functions.
Georg Brandl6caad7d2008-01-26 14:19:22 +00005796
5797- Patch #1720595: add T_BOOL to the range of structmember types.
5798
5799- Issue #1534: Added ``PyFloat_GetMax()``, ``PyFloat_GetMin()`` and
5800 ``PyFloat_GetInfo()`` to the float API.
5801
Georg Brandl3ee81df2008-05-17 18:14:43 +00005802- Issue #1521: On 64bit platforms, using PyArgs_ParseTuple with the t#
5803 of w# format code incorrectly truncated the length to an int, even
5804 when PY_SSIZE_T_CLEAN is set. The str.decode method used to return
5805 incorrect results with huge strings.
Georg Brandl6caad7d2008-01-26 14:19:22 +00005806
Georg Brandl3ee81df2008-05-17 18:14:43 +00005807- Issue #1629: Renamed Py_Size, Py_Type and Py_Refcnt to Py_SIZE,
5808 Py_TYPE and Py_REFCNT.

Georg Brandl3ee81df2008-05-17 18:14:43 +00005810- PEP 3123: Provide forward compatibility with Python 3.0, while
5811 keeping backwards compatibility. Add Py_Refcnt, Py_Type, Py_Size,
5812 and PyVarObject_HEAD_INIT.
Georg Brandl6caad7d2008-01-26 14:19:22 +00005813
Georg Brandl3ee81df2008-05-17 18:14:43 +00005814- Py_ssize_t fields work in structmember when HAVE_LONG_LONG is not
5815 defined.
Georg Brandl6caad7d2008-01-26 14:19:22 +00005816
5817- Patch #1733960: Allow T_LONGLONG to accept ints.

5824
5825- Fix some leftovers from the conversion from int to Py_ssize_t
5826 (relevant to strings and sequences of more than 2**31 items).
5827
5828- Make _PyGILState_NoteThreadState() static, it was not used anywhere
5829 outside of pystate.c and should not be necessary.
5830
Georg Brandl3ee81df2008-05-17 18:14:43 +00005831- ``PyImport_Import`` and ``PyImport_ImportModule`` now always do
5832 absolute imports. In earlier versions they might have used relative
5833 imports under some conditions.
Christian Heimes000a0742008-01-03 22:16:32 +00005834
Georg Brandl3ee81df2008-05-17 18:14:43 +00005835- Added case insensitive comparison methods ``PyOS_stricmp(char*,
5836 char*)`` and ``PyOS_strnicmp(char*, char*, Py_ssize_t)``.
Christian Heimes000a0742008-01-03 22:16:32 +00005837
Georg Brandl3ee81df2008-05-17 18:14:43 +00005838- Bug #1542693: remove semi-colon at end of PyImport_ImportModuleEx

Georg Brandl3ee81df2008-05-17 18:14:43 +00005845- Patch #1706: Drop support for Win9x, WinME and NT4. Python now
5846 requires Windows 2000 or greater. The _WINVER and NTDDI_VERSION
5847 macros are set to Win2k for x86/32bit builds and WinXP for AMD64
5848 builds.
Christian Heimes95d64472008-02-09 19:55:22 +00005849

Georg Brandl3ee81df2008-05-17 18:14:43 +00005863- Removed the macfs module. It had been deprecated since Python 2.5.
5864 This lead to the deprecation of macostools.touched() as it relied
5865 solely on macfs and was a no-op under OS X.
