136Core and Builtins
137-----------------
138
Philip Jenveyaebbaeb2010-04-06 23:24:45 +0000139- Issue #7301: Add environment variable $PYTHONWARNINGS.
140
Benjamin Peterson3a1dfa22010-04-06 21:50:00 +0000141- Issue #8329: Don't return the same lists from select.select when no fds are
142 changed.
143
Mark Dickinson82791672010-04-06 16:47:55 +0000144- Issue #8259: 1L << (2**31) no longer produces an 'outrageous shift error'
145 on 64-bit machines. The shift count for either left or right shift is
146 permitted to be up to sys.maxsize.
147
Benjamin Peterson4ceeeb02010-04-03 22:48:51 +0000148- Ensure that tokenization of identifiers is not affected by locale.

155 is called with a non-empty format string. This is an effort to
156 future-proof user code. If a derived class does not currently
157 implement __format__ but later adds its own __format__, it would
158 most likely break user code that had supplied a format string. This
159 will be changed to a DeprecationWaring in Python 3.3 and it will be
160 an error in Python 3.4.
161
Antoine Pitroua57df2c2010-03-31 21:32:15 +0000162- Issue #8268: Old-style classes (not just instances) now support weak

Georg Brandlba83f822010-03-14 09:50:54 +0000176 (SIGINT). If an error occurs while importing the site module, the error is
177 printed and Python exits. Initialize the GIL before importing the site
Victor Stinner66644262010-03-10 22:30:19 +0000178 module.
179
Collin Winter001a3952010-03-18 21:54:01 +0000180- Code objects now support weak references.

188 using the new attributes `ssl.OPENSSL_VERSION`, `ssl.OPENSSL_VERSION_INFO`
189 and `ssl.OPENSSL_VERSION_NUMBER`.
190
Benjamin Peterson76a23c12010-04-04 23:23:22 +0000191- Issue #8310: Allow dis to examine new style classes.
192
Mark Dickinson8a950712010-04-03 15:47:46 +0000193- Issue #8257: The Decimal construct now accepts a float instance
194 directly, converting that float to a Decimal of equal value:

200
Raymond Hettingera551f312010-04-04 18:34:45 +0000201- the functools module now has a total_ordering() class decorator
Georg Brandl4fabac52010-04-14 08:53:38 +0000202 to simplify the specification of rich comparisons.
Raymond Hettingera551f312010-04-04 18:34:45 +0000203
Raymond Hettingerbb006cf2010-04-04 21:45:01 +0000204- The functools module also adds cmp_to_key() as a tool to transition
Raymond Hettingera551f312010-04-04 18:34:45 +0000205 old-style comparison functions to new-style key-functions.
206
Mark Dickinson7c63eee2010-04-02 22:27:36 +0000207- Issue #8294: The Fraction constructor now accepts Decimal and float
208 instances directly.
209
Mark Dickinsone096e822010-04-02 10:17:07 +0000210- Issue #7279: Comparisons involving a Decimal signaling NaN now
211 signal InvalidOperation instead of returning False. (Comparisons
Mark Dickinsonf3eeca12010-04-02 10:35:12 +0000212 involving a quiet NaN are unchanged.) Also, Decimal quiet NaNs
213 are now hashable; Decimal signaling NaNs remain unhashable.
Mark Dickinsone096e822010-04-02 10:17:07 +0000214
Mark Dickinson99d80962010-04-02 08:53:22 +0000215- Issue #2531: Comparison operations between floats and Decimal

221 argument `-` which tells it to read files to compile from stdin. Each line
222 is read on demand and the named file is compiled immediately. (Original
223 patch by Piotr Ożarowski).
224
225- Issue #3135: Add inspect.getcallargs, which binds arguments to a function
226 like a normal call.
Benjamin Peterson7e213252010-03-30 17:58:13 +0000227
Florent Xicluna58b65662010-03-30 16:29:03 +0000228- Backwards incompatible change: Unicode codepoints line tabulation (0x0B) and
229 form feed (0x0C) are now considered linebreaks, as specified in Unicode
230 Standard Annex #14. See issue #7643.

234 a Fractions instance now raise TypeError instead of returning
235 True/False. This makes Fraction <=> complex comparisons consistent with
236 int <=> complex, float <=> complex, and complex <=> complex comparisons.
237
Michael Foorde6410c52010-03-29 20:04:23 +0000238- Addition of ``WeakSet`` to the ``weakref`` module.

336 integer format code, struct.pack first attempts to convert the non-integer
337 using its __index__ method. If that method is non-existent or raises
338 TypeError it goes on to try the __int__ method, as described below.

Georg Brandlba83f822010-03-14 09:50:54 +0000340- Issue #1530559: When passing a non-integer argument to struct.pack with *any*
341 integer format code (one of 'bBhHiIlLqQ'), struct.pack attempts to use the
342 argument's __int__ method to convert to an integer before packing. It also
343 produces a DeprecationWarning in this case. (In Python 2.6, the behaviour
344 was inconsistent: __int__ was used for some integer codes but not for others,
345 and the set of integer codes for which it was used differed between native
346 packing and standard packing.)

Georg Brandlba83f822010-03-14 09:50:54 +0000551- Issue #7712: test_support gained a new ``temp_cwd`` context manager which is
552 now also used by regrtest to run all the tests in a temporary directory. The
553 original CWD is saved in ``test.test_support.SAVEDCWD``. Thanks to Florent
554 Xicluna who helped with the patch.

571 and read operations on write-only file objects. On Windows, the system C
Georg Brandlba83f822010-03-14 09:50:54 +0000572 library would return a bogus result; on Solaris, it was possible to crash the
573 interpreter. Patch by Stefan Krah.

Georg Brandlba83f822010-03-14 09:50:54 +0000586- Issue #7766: Change ``sys.getwindowsversion()`` return value to a named tuple
587 and add the additional members returned in an OSVERSIONINFOEX structure. The
588 new members are service_pack_major, service_pack_minor, suite_mask, and
589 product_type.

Georg Brandlba83f822010-03-14 09:50:54 +0000591- Issue #7561: Operations on empty bytearrays (such as ``int(bytearray())``)
592 could crash in many places because of the ``PyByteArray_AS_STRING()`` macro
593 returning NULL. The macro now returns a statically allocated empty string
594 instead.

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

624
Georg Brandlba83f822010-03-14 09:50:54 +0000625- Issue #2746: Don't escape ampersands and angle brackets ("&", "<", ">") in
626 XML processing instructions and comments. These raw characters are allowed
627 by the XML specification, and are necessary when outputting e.g. PHP code in
628 a processing instruction. Patch by Neil Muller.

Antoine Pitroud840e512010-02-04 20:20:18 +0000636- Issue #4772: Raise a ValueError when an unknown Bluetooth protocol is
Georg Brandlba83f822010-03-14 09:50:54 +0000637 specified, rather than fall through to AF_PACKET (in the ``socket`` module).
Antoine Pitroud840e512010-02-04 20:20:18 +0000638 Also, raise ValueError rather than TypeError when an unknown TIPC address
639 type is specified. Patch by Brian Curtin.
640
Vinay Sajip28c382f2010-02-04 18:48:53 +0000641- logging: Implemented PEP 391.
642
Antoine Pitrouf3fa0742010-01-31 22:26:04 +0000643- Issue #6939: Fix file I/O objects in the `io` module to keep the original
Georg Brandlba83f822010-03-14 09:50:54 +0000644 file position when calling `truncate()`. It would previously change the file
645 position to the given argument, which goes against the tradition of
Antoine Pitrouf3fa0742010-01-31 22:26:04 +0000646 ftruncate() and other truncation APIs. Patch by Pascal Chambon.
647
Benjamin Petersone06f7112010-01-28 02:15:02 +0000648- UserDict is now a new-style class.
649
Georg Brandlba83f822010-03-14 09:50:54 +0000650- Issue #7610: Reworked implementation of the internal ``zipfile.ZipExtFile``
651 class used to represent files stored inside an archive. The new
652 implementation is significantly faster and can be wrapped in a
653 ``io.BufferedReader`` object for more speedups. It also solves an issue
654 where interleaved calls to ``read()`` and ``readline()`` give wrong results.
655 Patch by Nir Aides.

Georg Brandlba83f822010-03-14 09:50:54 +0000662- Issue #7773: Fix an UnboundLocalError in ``platform.linux_distribution()``
663 when the release file is empty.
Benjamin Petersona43f34c2010-01-25 03:31:13 +0000664
Georg Brandlba83f822010-03-14 09:50:54 +0000665- Issue #7748: Since unicode values are supported for some metadata options in
666 Distutils, the DistributionMetadata get_* methods will now return an utf-8
667 encoded string for them. This ensures that the upload and register commands
668 send the correct values to PyPI without any error.

Georg Brandlba83f822010-03-14 09:50:54 +0000670- Issue #1670765: Prevent ``email.generator.Generator`` from re-wrapping
R. David Murrayed44dfa2010-01-16 05:15:17 +0000671 headers in multipart/signed MIME parts, which fixes one of the sources of

742Core and Builtins
743-----------------
744
Georg Brandlba83f822010-03-14 09:50:54 +0000745- The ``__complex__()`` method is now looked up on the class of instances to
746 make it consistent with other special methods.
Benjamin Petersonecdae192010-01-04 00:43:01 +0000747
Antoine Pitrou5b7139a2010-01-02 21:12:58 +0000748- Issue #7462: Implement the stringlib fast search algorithm for the `rfind`,
749 `rindex`, `rsplit` and `rpartition` methods. Patch by Florent Xicluna.
750
Mark Dickinson1b34d252010-01-01 17:27:30 +0000751- Issue #5080: A number of functions and methods previously produced a
Georg Brandlba83f822010-03-14 09:50:54 +0000752 DeprecationWarning when passed a float argument where an integer was expected.
753 These functions and methods now raise TypeError instead. The majority of the
754 effects of this change are in the extension modules, but some core functions
755 and methods are affected: notably the 'chr', 'range' and 'xrange' builtins,
756 and many unicode/str methods.

768
Georg Brandlba83f822010-03-14 09:50:54 +0000769- Issue #1811: Improve accuracy and cross-platform consistency for true division
770 of integers: the result of a/b is now correctly rounded for ints a and b (at
771 least on IEEE 754 platforms), and in particular does not depend on the
772 internal representation of a long.
Mark Dickinson46572832009-12-27 14:55:57 +0000773
Georg Brandlba83f822010-03-14 09:50:54 +0000774- Issue #6108: ``unicode(exception)`` and ``str(exception)`` should return the
775 same message when only ``__str__()`` (and not ``__unicode__()``) is overridden
776 in the subclass.

780
Georg Brandlba83f822010-03-14 09:50:54 +0000781 These executables now work properly with the arch(1) command: ``arch -ppc
782 python`` will start a universal binary version of python in PPC mode (unlike
783 previous releases).
Ronald Oussoren92919a62009-12-24 13:30:58 +0000784

Georg Brandlba83f822010-03-14 09:50:54 +0000939- Issue #7117: ``repr(x)`` for a float x returns a result based on the shortest
940 decimal string that's guaranteed to round back to x under correct rounding
941 (with round-half-to-even rounding mode). Previously it gave a string based on
942 rounding x to 17 decimal digits. repr(x) for a complex number behaves
943 similarly. On platforms where the correctly-rounded strtod and dtoa code is
944 not supported (see below), repr is unchanged.
Mark Dickinsonb678de82009-11-19 18:41:49 +0000945
Georg Brandlba83f822010-03-14 09:50:54 +0000946- Issue #7117: On almost all platforms: float-to-string and string-to-float
947 conversions within Python are now correctly rounded. Places these conversions
948 occur include: str for floats and complex numbers; the float and complex
949 constructors; old-style and new-style numeric formatting; serialization and
950 deserialization of floats and complex numbers using marshal, pickle and json;
951 parsing of float and imaginary literals in Python code; Decimal-to-float
952 conversion.
Mark Dickinsonb678de82009-11-19 18:41:49 +0000953
Georg Brandlba83f822010-03-14 09:50:54 +0000954 The conversions use a Python-adapted version of David Gay's well-known dtoa.c,
955 providing correctly-rounded strtod and dtoa C functions. This code is
956 supported on Windows, and on Unix-like platforms using gcc, icc or suncc as
957 the C compiler. There may be a small number of platforms on which correct
958 operation of this code cannot be guaranteed, so the code is not used: notably,
959 this applies to platforms where the C double format is not IEEE 754 binary64,
960 and to platforms on x86 hardware where the x87 FPU is set to 64-bit precision
961 and Python's configure script is unable to determine how to change the FPU
962 precision. On these platforms conversions use the platform strtod and dtoa,
963 as before.

Georg Brandlba83f822010-03-14 09:50:54 +0000965- Issue #7117: Backport round implementation from Python 3.x. ``round()`` now
966 uses the correctly-rounded string <-> float conversions described above (when
967 available), and so produces correctly rounded results that will display nicely
968 under the float repr. There are two related small changes: (1) round now
969 accepts any class with an ``__index__()`` method for its second argument (but
970 no longer accepts floats for the second argument), and (2) an excessively
971 large second integer argument (e.g., ``round(1.234, 10**100)``) no longer
972 raises an exception.

Georg Brandlba83f822010-03-14 09:50:54 +00001119- Issue #5920: For ``float.__format__()``, change the behavior with the empty
1120 presentation type (that is, not one of 'e', 'f', 'g', or 'n') to be like 'g'
1121 but with at least one decimal point and with a default precision
1122 of 12. Previously, the behavior the same but with a default precision of 6.
1123 This more closely matches ``str()``, and reduces surprises when adding
1124 alignment flags to the empty presentation type. This also affects the new
1125 complex.__format__ in the same way.
1126
1127- Issue #5890: In subclasses of 'property' the __doc__ attribute was shadowed by

1264
Georg Brandlba83f822010-03-14 09:50:54 +00001265- Issue #1180193: When importing a module from a .pyc (or .pyo) file with an
1266 existing .py counterpart, override the co_filename attributes of all code
1267 objects if the original filename is obsolete (which can happen if the file has
1268 been renamed, moved, or if it is accessed through different paths). Patch by
1269 Ziga Seilnacht and Jean-Paul Calderone.

Hirokazu Yamamoto99a1b202009-01-01 15:45:39 +00001273- Issue #4797: IOError.filename was not set when _fileio.FileIO failed to open
1274 file with `str' filename on Windows.
1275
Antoine Pitrouaa687902009-01-01 14:11:22 +00001276- Issue #3680: Reference cycles created through a dict, set or deque iterator
1277 did not get collected.
1278
Georg Brandlba83f822010-03-14 09:50:54 +00001279- Issue #4701: PyObject_Hash now implicitly calls PyType_Ready on types where
1280 the tp_hash and tp_dict slots are both NULL.
Nick Coghlan180e4002008-12-30 01:18:48 +00001281
Benjamin Peterson7af65562008-12-29 17:56:58 +00001282- Issue #4764: With io.open, IOError.filename is set when trying to open a
1283 directory on POSIX systems.
1284
Benjamin Petersonfe231b02008-12-29 17:47:42 +00001285- Issue #4764: IOError.filename is set when trying to open a directory on POSIX
1286 systems.
1287
Georg Brandl6425a2f2008-12-28 11:54:53 +00001288- Issue #4759: None is now allowed as the first argument of
Georg Brandlba83f822010-03-14 09:50:54 +00001289 ``bytearray.translate()``. It was always allowed for ``bytes.translate()``.
Georg Brandl6425a2f2008-12-28 11:54:53 +00001290
Skip Montanarof205c132008-12-23 03:30:15 +00001291- Added test case to ensure attempts to read from a file opened for writing
1292 fail.
1293
Georg Brandlba83f822010-03-14 09:50:54 +00001294- Issue #2467: gc.DEBUG_STATS reported invalid elapsed times. Also, always print
1295 elapsed times, not only when some objects are uncollectable/unreachable.
1296 Original patch by Neil Schemenauer.
Antoine Pitrou73c0e652008-12-17 22:46:54 +00001297

Georg Brandlba83f822010-03-14 09:50:54 +00001308- Issue #4445: Replace ``sizeof(PyStringObject)`` with
1309 ``offsetof(PyStringObject, ob_sval) + 1`` when allocating memory for str
1310 instances. On a typical machine this saves 3 bytes of memory (on average) per
1311 string allocation.
Mark Dickinson826f3fe2008-12-05 21:55:28 +00001312
Amaury Forgeot d'Arcdc619012008-11-22 20:01:18 +00001313- Issue #3996: On Windows, the PyOS_CheckStack function would cause the
1314 interpreter to abort ("Fatal Python error: Could not reset the stack!")
1315 instead of throwing a MemoryError.
1316
Georg Brandlba83f822010-03-14 09:50:54 +00001317- Issue #3689: The list reversed iterator now supports __length_hint__ instead
1318 of __len__. Behavior now matches other reversed iterators.
Raymond Hettinger7989a4d2008-12-03 15:42:10 +00001319
Benjamin Petersonc078f922008-11-21 22:27:24 +00001320- Issue #4367: Python would segfault during compiling when the unicodedata
1321 module couldn't be imported and \N escapes were present.
1322
Georg Brandlba83f822010-03-14 09:50:54 +00001323- Issue #4233: Changed semantic of ``_fileio.FileIO``'s ``close()`` method on
1324 file objects with closefd=False. The file descriptor is still kept open but
1325 the file object behaves like a closed file. The ``FileIO`` object also got a
1326 new readonly attribute ``closefd``.
Amaury Forgeot d'Arc32265652008-11-20 23:34:31 +00001327
Benjamin Peterson46cc6d12008-11-19 21:49:09 +00001328- Issue #4348: Some bytearray methods returned that didn't cause any change to
1329 the bytearray, returned the same bytearray instead of a copy.
1330
Georg Brandlba83f822010-03-14 09:50:54 +00001331- Issue #4317: Fixed a crash in the ``imageop.rgb2rgb8()`` function.

Benjamin Peterson273c2332008-11-17 22:39:09 +00001333- Issue #4230: If ``__getattr__`` is a descriptor, it now functions correctly.
1334
Benjamin Peterson6624a9f2008-11-03 15:14:51 +00001335- Issue #4048: The parser module now correctly validates relative imports.
1336
Benjamin Petersondcee09d2008-10-31 02:16:05 +00001337- Issue #4225: ``from __future__ import unicode_literals`` didn't work in an
1338 exec statement.
1339
Georg Brandlba83f822010-03-14 09:50:54 +00001340- Issue #4176: Fixed a crash when pickling an object which ``__reduce__`` method
1341 does not return iterators for the 4th and 5th items.
Amaury Forgeot d'Arc69a9c5b2008-10-30 21:18:34 +00001342
Benjamin Petersonbdca9422008-10-26 20:21:13 +00001343- Issue #4209: Enabling unicode_literals and the print_function in the same
1344 __future__ import didn't work.
1345
Benjamin Peterson399b1fe2008-10-25 02:53:28 +00001346- Using ``nonlocal`` as a variable name will now raise a Py3k SyntaxWarning
Georg Brandl7fb00ad2008-10-25 07:00:52 +00001347 because it is a reserved word in 3.x.
Benjamin Peterson399b1fe2008-10-25 02:53:28 +00001348
Georg Brandlba83f822010-03-14 09:50:54 +00001349- On windows, ``os.chdir()`` given unicode was not working if
1350 GetCurrentDirectoryW returned a path longer than MAX_PATH. (But It's doubtful
1351 this code path is really executed because I cannot move to such directory on
1352 win2k)
Hirokazu Yamamoto10a018c2008-10-09 10:00:30 +00001353
Georg Brandlba83f822010-03-14 09:50:54 +00001354- Issue #4069: When ``set.remove(element)`` is used with a set element, the
1355 element is temporarily replaced with an equivalent frozenset. But the
1356 eventual KeyError would always report the empty ``frozenset()`` as the missing
1357 key. Now it correctly refers to the initial element.
Amaury Forgeot d'Arcd78b9dc2008-10-07 20:32:10 +00001358
Georg Brandlba83f822010-03-14 09:50:54 +00001359- Issue #4509: Various issues surrounding resize of bytearray objects to which
1360 there are buffer exports.

1365
Gregory P. Smithae91d092009-03-02 05:13:57 +00001366- The re.sub(), re.subn() and re.split() functions now accept a flags parameter.
1367
Georg Brandlba83f822010-03-14 09:50:54 +00001368- Issue #3845: In PyRun_SimpleFileExFlags avoid invalid memory access with short

Matthias Klose91a3b9e2009-04-05 21:19:13 +00001371- Issue #1113244: Py_XINCREF, Py_DECREF, Py_XDECREF: Add `do { ... } while (0)'
1372 to avoid compiler warnings.
Matthias Klose0610e082009-04-05 12:43:08 +00001373
Gregory P. Smith2b3eb372009-04-05 23:48:26 +00001374- Issue #5705: os.setuid() would not accept values > 2**31-1 but pwd.getpwnam()
1375 returned them on 64bit platforms.
1376
Walter Dörwalded960ac2009-05-03 22:36:33 +00001377- Issue #5108: Handle %s like %S and %R in PyUnicode_FromFormatV(): Call
1378 PyUnicode_DecodeUTF8() once, remember the result and output it in a second
1379 step. This avoids problems with counting UTF-8 bytes that ignores the effect
1380 of using the replace error handler in PyUnicode_DecodeUTF8().
1381
Walter Dörwald726ba8e2009-05-06 14:32:35 +00001382- Issue #3739: The unicode-internal encoder now reports the number of characters
1383 consumed like any other encoder (instead of the number of bytes).
1384
Georg Brandlba83f822010-03-14 09:50:54 +00001385- Issue #2422: When compiled with the ``--with-valgrind`` option, the pymalloc
1386 allocator will be automatically disabled when running under Valgrind. This
1387 gives improved memory leak detection when running under Valgrind, while taking
1388 advantage of pymalloc at other times.

Guilherme Polo7f146ab2009-06-21 17:22:50 +00002630- Issue #5450: Moved tests involving loading tk from Lib/test/test_tcl to
2631 Lib/lib-tk/test/test_tkinter/test_loadtk. With this, these tests demonstrate
Georg Brandlba83f822010-03-14 09:50:54 +00002632 the same behaviour as test_ttkguionly (and now also test_tk) which is to skip
2633 the tests if DISPLAY is defined but can't be used.

2639 import both normal and optimised versions of modules. test_heapq and
2640 test_warnings have been adjusted to use it, tests for other modules with both
2641 C and Python implementations in the stdlib can be adjusted to use it over
2642 time.

2651 should cause a test to be skipped are now done using import_module from test
2652 support, which does the conversion.

Martin v. Löwis9fa5a282008-09-11 06:53:30 +00002753- Issue #3642: Suppress warning in obmalloc when size_t is larger than uint.
2754
Amaury Forgeot d'Arc05e34492008-09-10 22:04:45 +00002755- Issue #3743: In a few places, PY_FORMAT_SIZE_T was incorrectly used with
2756 PyString_FromFormat or PyErr_Format to display size_t values. The macro
2757 PY_FORMAT_SIZE_T is designed to select the correct format for the OS
2758 ``printf`` function, whereas PyString_FromFormat has an independent
2759 implementation and uses "%zd" on all platforms for size_t values.
2760 This makes a difference on win64, where ``printf`` needs "%Id" to display
2761 64bit values.

Benjamin Peterson97179b02008-09-09 20:55:01 +00002763- Issue #3634: _weakref.ref(Exception).__init__() gave invalid return value on

2767 object; previously an int would be returned for small values. the __long__

Amaury Forgeot d'Arc3571fbf2008-09-01 19:52:00 +00002771- Issue #3751: str.rpartition would perform a left-partition when called with

Vinay Sajip35e3b032008-09-01 14:33:59 +00002777 PyArg_ParseTuple and friends, which occurred when the argument for "s*"
Antoine Pitroud4ae97b2008-08-29 18:39:48 +00002778 was correctly parsed but parsing of subsequent arguments failed.
2779
Vinay Sajip35e3b032008-09-01 14:33:59 +00002780- Issue #2534: speed up isinstance() and issubclass() by 50-70%, so as to
Antoine Pitrou0668c622008-08-26 22:42:08 +00002781 match Python 2.5 speed despite the __instancecheck__ / __subclasscheck__
2782 mechanism. In the process, fix a bug where isinstance() and issubclass(),
2783 when given a tuple of classes as second argument, were looking up
2784 __instancecheck__ / __subclasscheck__ on the tuple rather than on each
2785 type object.
2786
Neal Norwitz18aa3882008-08-24 05:04:52 +00002787- Fix crashes on memory allocation failure found with failmalloc.

Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00002924What's New in Python 2.6 beta 3?
2925================================
2926
Barry Warsaw07a4a382008-08-21 01:15:08 +00002927*Release date: 20-Aug-2008*
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00002928
2929Core and Builtins
2930-----------------
2931
Guido van Rossumf8402962008-08-20 15:01:50 +00002932- Issue #1878: Remove Py_TPFLAGS_HAVE_VERSION_TAG from
2933 Py_TPFLAGS_DEFAULT when not building the core. This means 3rd party
2934 extensions do not automatically benefit from the class attribute
2935 cache; they will have to explicitly add Py_TPFLAGS_HAVE_VERSION_TAG
2936 to their tp_flags field if they care. This is a backwards
2937 compatibility feature; in 3.0, all types will use the cache by
2938 default.
2939
Benjamin Petersonf647dc12008-08-20 01:27:30 +00002940- Keyword arguments can now follow starred arguments. (``f(a, *args,
2941 keyword=23)`` is now valid syntax.)
2942
Thomas Heller0ad5ae02008-08-19 19:25:04 +00002943- ctypes function pointers that are COM methods have a boolean True
2944 value again.
2945
Martin v. Löwisf91d46a2008-08-12 14:49:50 +00002946- Issue #3139: Make buffer-interface thread-safe wrt. PyArg_ParseTuple,
2947 by denying s# to parse objects that have a releasebuffer procedure,
2948 and introducing s*.
2949
Georg Brandl1e13ea92008-08-11 09:07:59 +00002950- Issue #3537: Fix an assertion failure when an empty but presized dict
2951 object was stored in the freelist.
2952
Mark Dickinsonb6467572008-08-04 21:30:09 +00002953- Issue #1481296: Make long(float('nan')) and int(float('nan')) raise
2954 ValueError consistently across platforms.
2955
Amaury Forgeot d'Arc39fd6722008-07-31 21:28:03 +00002956- Issue #3479: On platforms where sizeof(int) is smaller than sizeof(long)
2957 (64bit Unix, for example), unichr() would truncate its argument and return
2958 u'\x00' for unichr(2**32). Now it properly raises an OverflowError.
2959
Neal Norwitze7d8be82008-07-31 17:17:14 +00002960- Apply security patches from Apple.
2961
Amaury Forgeot d'Arc246daed2008-07-31 00:42:16 +00002962- Issue #2542: Now that issubclass() may call arbitrary code, ensure that
2963 PyErr_ExceptionMatches returns 0 when an exception occurs there.
2964
Antoine Pitrou92f82162008-07-25 22:22:08 +00002965- Issue #1819: function calls with several named parameters are now on
2966 average 35% faster (as measured by pybench).
2967
Amaury Forgeot d'Arce4921fe2008-07-21 22:00:38 +00002968- Issue #2378: An unexpected UnboundLocalError or NameError could appear when
2969 the python debugger steps into a class statement: the free variables (local
2970 variables defined in an outer scope) would be deleted from the outer scope.
2971
Gregory P. Smith0470bab2008-07-22 04:46:32 +00002972- Issue #2620: Overflow checking when allocating or reallocating memory
2973 was not always being done properly in some python types and extension
2974 modules. PyMem_MALLOC, PyMem_REALLOC, PyMem_NEW and PyMem_RESIZE have
2975 all been updated to perform better checks and places in the code that
2976 would previously leak memory on the error path when such an allocation
2977 failed have been fixed.
2978
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00002979Library
2980-------
2981
Hirokazu Yamamoto838c79f2008-08-20 13:14:07 +00002982- Issue #3612: Added some missing basic types in ctypes.wintypes.
2983
Benjamin Petersone977ad42008-08-20 01:42:01 +00002984- The methods ``is_in_tuple()``, ``is_vararg()``, and ``is_keywordarg()`` of
2985 symtable.Symbol have been deprecated for removal in 3.0 and the next release.
2986
Amaury Forgeot d'Arc351ffb82008-08-18 19:23:47 +00002987- Issue #2234: distutils failed for some versions of the cygwin compiler. The
2988 version reported by these tools does not necessarily follow the python
2989 version numbering scheme, so the module is less strict when parsing it.
2990
Nick Coghlanf70385a2008-08-18 12:42:46 +00002991- Issue #2235: Added Py3k warnings for types which will become unhashable
2992 under the stricter __hash__ inheritance rules in 3.0. Several types
2993 which did not meet the rules for hash invariants and were already
2994 unhashable in 3.0 have now been explicitly flagged as unhashable in
2995 2.6 as well (collections.Mapping, collections.Set, unittest.TestSuite,
2996 xml.dom.minidom.NamedNodeMap, numbers.Number, UserList.UserList)
2997
Brett Cannon88f801d2008-08-18 00:46:22 +00002998- Update __all__ for cookielib, csv, os, urllib2, and weakref to include things
2999 imported into the module but exposed as part of the module's API.
3000
Brett Cannon7b96f072008-08-18 00:41:11 +00003001- Remove an unneeded import of abc.ABCMeta from 'inspect'.
3002
Brett Cannon46225e72008-08-18 00:36:52 +00003003- Remove unneeded imports of 'sys' and 'warnings' from 'io'.
3004
Brett Cannon25c9d6a2008-08-17 22:10:11 +00003005- Remove unneeded imports of 'warnings' from shelve, filecmp, and dummy_thread.
3006
Hirokazu Yamamoto41a81eb2008-08-17 13:10:46 +00003007- Issue #3575: Incremental decoder's decode function now takes bytearray
3008 by using 's*' instead of 't#'.
3009
Mark Dickinson3e4caeb2009-02-21 20:27:01 +00003010- Issue #2222: Fixed reference leak when occurred os.rename()
Hirokazu Yamamoto7f30a682008-08-17 09:46:56 +00003011 fails unicode conversion on 2nd parameter. (windows only)
3012
Facundo Batista94f243a2008-08-17 03:38:39 +00003013- Issue 2464. urllib2 now supports a malformation in the URL received
3014 in a redirect.
3015
Brett Cannonabe423e2008-08-16 21:47:07 +00003016- Silence the DeprecationWarning raised when importing mimetools in
Brett Cannon721b1452008-08-16 22:00:27 +00003017 BaseHTTPServer, cgi (and rfc822), httplib.
Brett Cannonabe423e2008-08-16 21:47:07 +00003018
Facundo Batistaeb90b782008-08-16 14:44:07 +00003019- Issue #2776: fixed small issue when handling an URL with double slash
3020 after a 302 response in the case of not going through a proxy.
3021
Antoine Pitroub90a8be2008-08-15 21:03:21 +00003022- Issue #2676: in the email package, content-type parsing was hanging on
3023 pathological input because of quadratic or exponential behaviour of a
3024 regular expression.
3025
Antoine Pitrou11ec65d2008-08-14 21:04:30 +00003026- Issue #3476: binary buffered reading through the new "io" library is now
3027 thread-safe.
3028
Brett Cannonbf3157b2008-08-14 05:00:03 +00003029- Silence the DeprecationWarning of rfc822 when it is imported by mimetools
3030 since mimetools itself is deprecated. Because modules are cached, all
3031 subsequent imports of rfc822 will not raise a visible DeprecationWarning.
3032
Antoine Pitrou9fcd4b32008-08-11 17:21:36 +00003033- Issue #3134: shutil referenced undefined WindowsError symbol.
3034
Robert Schuppenies14646332008-08-10 11:01:53 +00003035- Issue #1342811: Fix leak in Tkinter.Menu.delete. Commands associated to
3036 menu entries were not deleted.
3037
Brett Cannon83e81842008-08-09 23:30:55 +00003038- Copied the implementation of reduce() to _functools.reduce() to have a
3039 version that did not raise a DeprecationWarning under -3.
3040
Antoine Pitrou76b8bee2008-08-09 17:27:23 +00003041- Issue #3205: When iterating over a BZ2File fails allocating memory, raise
3042 a MemoryError rather than silently stop the iteration.
3043
Guido van Rossum59ce9012008-08-09 14:55:34 +00003044- Issue #3487: sre "bytecode" validator. Passing invalid "re-bytecode"
3045 to _sre.compile() will now be rejected. This should not affect anybody
3046 since the re.compile() function never generates invalid re-bytecode.
3047
Skip Montanaroa032bf42008-08-08 22:52:51 +00003048- Issue #3436: Make csv.DictReader's fieldnames attribute a property so that
3049 upon first access it can be automatically initialized from the csv file if
3050 it wasn't initialized during instantiation.
3051
Brett Cannon3aa2a492008-08-06 22:28:09 +00003052- Issue #2338: Create imp.reload() to help with transitioning to Python 3.0 as
3053 the reload() built-in has been removed.
3054
Brett Cannon7e30b672008-08-04 21:52:25 +00003055- Changed code in the following modules/packages to remove warnings raised
Brett Cannonc1b76e42008-08-09 23:06:16 +00003056 while running under the ``-3`` flag: aifc, asynchat, asyncore, bdb, bsddb,
Brett Cannon047e4a92008-08-17 04:16:04 +00003057 ConfigParser, cookielib, csv, difflib, distutils, DocXMLRPCServer, email,
3058 filecmp, fileinput, inspect, logging, modulefinder, pdb, pickle, profile,
3059 pstats, pydoc, re, rlcompleter, SimpleXMLRPCServer, shelve, socket,
3060 subprocess, sqlite3, tarfile, Tkinter, test.test_support, textwrap,
3061 threading, tokenize, traceback, urlparse, wsgiref, xml, xmlrpclib.
Brett Cannon7e30b672008-08-04 21:52:25 +00003062
Lars Gustäbel727bd0b2008-08-02 11:26:39 +00003063- Issue #3039: Fix tarfile.TarFileCompat.writestr() which always
3064 raised an AttributeError.
3065
Benjamin Peterson01a24322008-07-28 23:35:27 +00003066- Issue #2523: Fix quadratic behaviour when read()ing a binary file without
Antoine Pitroude781a42008-08-09 12:43:23 +00003067 asking for a specific length. This problem only affected files opened
3068 using the new "io" module, not the built-in open() function.
Benjamin Peterson01a24322008-07-28 23:35:27 +00003069
Mark Dickinsonfe84cce2008-07-27 06:39:07 +00003070- Issue #3449: Update decimal module to use most recent specification
3071 (v. 1.68) and tests (v. 2.58) from IBM.
3072
Skip Montanarof9ac43f2008-07-27 00:50:41 +00003073- Issue 3437: Bug fix in robotparser parsing of Allow: lines.
3074
Raymond Hettinger8c664e82008-07-25 18:43:33 +00003075- Issue 1592: Improve error reporting when operations are attempted
3076 on a closed shelf.

3081
3082- Issue #3303: Fix a crash in locale.strcoll() when calling it with
3083 invalid arguments.
3084
3085- Issue #3302: Fix several crashes when calling locale's gettext functions
3086 with None arguments.
3087
3088- Issue #3389: Allow resolving dotted names for handlers in logging
3089 configuration files.
3090
3091- Deprecate the sunaudio module for removal in Python 3.0.
3092
Antoine Pitrou5fdfa3e2008-07-25 19:42:26 +00003093- Issue #3394: zipfile.writestr sets external attributes when passed a
3094 file name rather than a ZipInfo instance, so files are extracted with
3095 mode 0600 rather than 000 under Unix.
3096
Gregory P. Smitha36f8fe2008-08-04 00:13:29 +00003097- Issue #1857: subprocess.Popen.poll gained an additional _deadstate keyword
3098 argument in python 2.5, this broke code that subclassed Popen to include its
3099 own poll method. Fixed my moving _deadstate to an _internal_poll method.

3107-------------
3108
Nick Coghlan6e8fef02008-08-18 13:14:22 +00003109- Issue #2235: the C API function PyObject_HashNotImplemented and its
3110 interaction with the tp_hash slot (added in 2.6b2) are now documented
3111
Nick Coghlan2a0c2b12008-08-04 12:47:17 +00003112- Issue #643841: The language reference now provides more detailed
3113 coverage of the lookup process for special methods. The disclaimers
3114 regarding lack of coverage of new-style classes have also been
3115 removed, since the coverage is now fairly reasonable.

Raymond Hettingere3ae6552008-06-20 04:18:15 +00003118What's New in Python 2.6 beta 2?
3119================================
3120
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00003121*Release date: 17-Jul-2008*
3122
Raymond Hettingere3ae6552008-06-20 04:18:15 +00003123Core and Builtins
3124-----------------
3125
Georg Brandl3e483f62008-07-16 22:57:41 +00003126- Issue #3156: Fix inconsistent behavior of the bytearray type: all
3127 its methods now allow for items objects that can be converted to
3128 an integer using operator.index().
3129
Mark Dickinson64b7e502008-07-16 09:40:03 +00003130- Issue #3360: Fix incorrect parsing of '020000000000.0', which
3131 produced a ValueError instead of giving the correct float.
3132
Eric Smitha5fa5a22008-07-16 00:11:49 +00003133- Issue #3083: Add alternate (#) formatting for bin, oct, hex output
3134 for str.format(). This adds the prefix 0b, 0o, or 0x, respectively.
3135
Mark Dickinson7103aa42008-07-15 19:08:33 +00003136- Issue #3008: the float type has a new instance method 'float.hex'
3137 and a new class method 'float.fromhex' to convert floating-point
3138 numbers to and from hexadecimal strings, respectively.
3139
Nick Coghlan6d6bd442008-07-15 15:40:22 +00003140- Issue #2235: __hash__ is once again inherited by default. To allow
3141 collections.Hashable to remain meaningful in the presence of the
3142 default hash implementation (object.__hash__), it is now possible
3143 to explicit block inheritance of hash by setting __hash__=None at
3144 the Python level, or tp_hash=PyObject_HashNotImplemented at the C
3145 level.
3146
Nick Coghlanb028f502008-07-13 14:52:36 +00003147- Issue #3221: Issue a RuntimeWarning instead of raising SystemError if
3148 the parent module cannot be found while performing an absolute import.
3149 This means that an incorrectly defined __package__ attribute will
3150 now only prevent relative imports in that module rather than causing
3151 all imports from that module to fail.
3152
Nick Coghlan14ff9942008-07-08 14:21:42 +00003153- Issue #2517: Allow unicode messages in Exceptions again by correctly
3154 bypassing the instance dictionary when looking up __unicode__ on
3155 new-style classes.
3156
Amaury Forgeot d'Arcbdd941f2008-07-01 20:38:04 +00003157- Issue #3242: Fix a crash inside the print statement, if sys.stdout is
3158 set to a custom object whose write() method happens to install
3159 another file in sys.stdout.
3160
Amaury Forgeot d'Arc1f40c8a2008-06-30 22:42:40 +00003161- Issue #3088: Corrected a race condition in classes derived from
3162 threading.local: the first member set by a thread could be saved in
3163 another thread's dictionary.
3164
Mark Dickinson1ec2fcd2008-06-20 14:53:43 +00003165- Issue #3004: Minor change to slice.indices(): the start and stop
3166 arguments are now treated identically, making the behaviour easier
3167 to describe and understand. For example, slice(None, -10,
3168 1).indices(9) now returns (0, 0, 1) instead of (0, -1, 1), and
3169 slice(None, 10, -1).indices(10) returns (9, 9, -1) instead of (9,
3170 10, -1).
3171
Georg Brandl278fc502008-07-19 12:46:12 +00003172- Issue #3219: Calling a function with repeated keyword arguments,
3173 f(a=2, a=23), would not cause a syntax error. This was a regression
3174 from 2.4 caused by the switch to the new compiler.
Benjamin Peterson175e4d92008-07-01 19:34:52 +00003175
Georg Brandl278fc502008-07-19 12:46:12 +00003176- Issue #2862: Make int and float freelist management consistent with
3177 other freelists. Changes their CompactFreeList apis into
3178 ClearFreeList apis and calls them via gc.collect().
Gregory P. Smith2fe77062008-07-06 03:35:58 +00003179

3181-------
3182
Thomas Heller57adf222008-08-14 19:10:48 +00003183- Issue #3554: ctypes.string_at and ctypes.wstring_at did call Python
3184 api functions without holding the GIL, which could lead to a fatal
3185 error when they failed.
3186
Martin v. Löwisaabf4042008-08-02 07:20:25 +00003187- Issue #799428: Fix Tkinter.Misc._nametowidget to unwrap Tcl command objects.

Jesse Noller13e9d582008-07-16 14:32:36 +00003195- Issue #3125: Remove copy_reg in multiprocessing and replace it with
3196 ForkingPickler.register() to resolve conflict with ctypes.
3197
Vinay Sajip51e65192008-07-18 09:01:10 +00003198- Issue #3090: Fixed ARCHFLAGS parsing on OS/X
Jesse Noller13e9d582008-07-16 14:32:36 +00003199
Thomas Heller880f5292008-07-15 19:39:38 +00003200- Issue #3313: Fixed a crash when a failed dlopen() call does not set
3201 a valid dlerror() message.
3202
Thomas Heller2bad6572008-07-15 17:19:50 +00003203- Issue #3258: Fixed a crash when a ctypes POINTER type to an
3204 incomplete structure was created.
3205
Brett Cannon3d0b9f02008-07-13 01:15:07 +00003206- Issue #3339: dummy_thread.acquire() should not return None.
3207
Raymond Hettingerb01713e2008-07-10 14:34:57 +00003208- Issue #3285: Fractions from_float() and from_decimal() accept Integral arguments.
3209
Andrew M. Kuchlingcc3f2b12008-07-10 14:43:31 +00003210- Issue #3301: Bisect module behaved badly when lo was negative.

3621
Ronald Oussoren5640ce22008-06-05 12:58:24 +00003622- On MacOS X it is now possible to install the framework in 64-bit
3623 mode or even as a 4-way universal binary (that is, PPC, i386,
Georg Brandl5cc774e2008-06-11 20:28:06 +00003624 PPC64 and x86_64 support in one binary).
Ronald Oussoren5640ce22008-06-05 12:58:24 +00003625
3626 This is controlled by the configure argument ``--with-universal-archs``:
3627
3628 - ``--with-universal-archs=all``: install 4-way universal
3629
3630 - ``--with-universal-archs=32-bit``: install 2-way universal, 32-bit (the default)
3631
3632 - ``--with-universal-archs=64-bit``: install 2-way universal, 64-bit
3633
3634 This option should be used in combination with ``--enable-universalsdk=``.
3635
3636 NOTE: 64-bit and 4-way builds are only suppported on Mac OS X 10.5 (or later).

3673 two handlers that derive the same default base class.
Amaury Forgeot d'Arc96865852008-04-22 21:14:41 +00003674
Christian Heimese74c8f22008-04-19 02:23:57 +00003675- Added kill, terminate and send_signal(sig) to subprocess.Popen.
3676
Georg Brandl3ee81df2008-05-17 18:14:43 +00003677- Added phase(z) -> phi, polar(z) -> r, phi and rect(r, phi) -> z to
3678 the cmath module.
Christian Heimes6f341092008-04-18 23:13:07 +00003679

Georg Brandl3ee81df2008-05-17 18:14:43 +00003686- Issue #1631171: Re-implement the 'warnings' module in C (the
3687 original Python code has been kept as backup). This will allow for
3688 using the 'warning's machinery in such places as the parser where
3689 use of pure Python code is not possible. Both the ``showarning()``
3690 and ``formatwarning()`` gain an optional 'line' argument which is
3691 not called by default for backwards-compatibility reasons. Setting
3692 ``warnings.showwarning()`` to an implementation that lacks support
3693 for the ``line`` argument will raise a DeprecationWarning.

Neal Norwitz2b0bea52008-04-25 03:40:17 +00003715- Issue #2682: ctypes callback functions no longer contain a cyclic
Thomas Hellerbf027c42008-04-24 18:14:19 +00003716 reference to themselves.
3717
Gregory P. Smithd59fefb2008-04-22 08:11:33 +00003718- The getpass module has been improved on Unix. It now uses /dev/tty
3719 by default and uses stderr instead of stdout. A GetPassWarning is
3720 issued when input echo cannot be controlled.
Gregory P. Smith41e30182008-04-21 21:31:08 +00003721

Georg Brandl3ee81df2008-05-17 18:14:43 +00003735- Issue #2513: distutils on Windows is now capable of cross-compiling
Mark Hammond495cf992008-04-07 01:53:39 +00003736 extension modules between 32 and 64 bit platforms. See the distutls

Georg Brandl3ee81df2008-05-17 18:14:43 +00003756- Issue #2550: The approach used by client/server code for obtaining
3757 ports to listen on in network-oriented tests has been refined in an
3758 effort to facilitate running multiple instances of the entire
3759 regression test suite in parallel without issue.
3760 test_support.bind_port() has been fixed such that it will always
3761 return a unique port -- which wasn't always the case with the
3762 previous implementation, especially if socket options had been set
3763 that affected address reuse (i.e. SO_REUSEADDR, SO_REUSEPORT). The
3764 new implementation of bind_port() will actually raise an exception
3765 if it is passed an AF_INET/SOCK_STREAM socket with either the
3766 SO_REUSEADDR or SO_REUSEPORT socket option set. Furthermore, if
3767 available, bind_port() will set the SO_EXCLUSIVEADDRUSE option on
3768 the socket it's been passed. This currently only applies to
3769 Windows. This option prevents any other sockets from binding to the
3770 host/port we've bound to, thus removing the possibility of the
3771 'non-deterministic' behaviour, as Microsoft puts it, that occurs
3772 when a second SOCK_STREAM socket binds and accepts to a host/port
3773 that's already been bound by another socket. The optional preferred
3774 port parameter to bind_port() has been removed. Under no
3775 circumstances should tests be hard coding ports!
3776
3777 test_support.find_unused_port() has also been introduced, which will
3778 pass a temporary socket object to bind_port() in order to obtain an
3779 unused port. The temporary socket object is then closed and
3780 deleted, and the port is returned. This method should only be used
3781 for obtaining an unused port in order to pass to an external program
3782 (i.e. the -accept [port] argument to openssl's s_server mode) or as
3783 a parameter to a server-oriented class that doesn't give you direct
3784 access to the underlying socket used.
3785
3786 Finally, test_support.HOST has been introduced, which should be used
3787 for the host argument of any relevant socket calls (i.e. bind and
3788 connect).

4062Core and builtins
4063-----------------
4064
Fred Drakea8ee94b2008-03-01 02:45:07 +00004065- Issue #2051: pyc and pyo files are no longer created with permission
Barry Warsaw52973612008-03-01 02:23:38 +00004066 644. The mode is now inherited from the py file.
Christian Heimes40346852008-02-23 17:52:07 +00004067
Georg Brandlad61bc82008-02-23 15:11:18 +00004068- Issue #2067: file.__exit__() now calls subclasses' close() method.
4069
4070- Patch #1759: Backport of PEP 3129 class decorators.
Christian Heimes5224d282008-02-23 15:01:05 +00004071
Vinay Sajipb7edfc42008-04-02 21:10:23 +00004072- Issue #1881: An internal parser limit has been increased. Also see
Facundo Batistafc2d0102008-02-23 12:01:13 +00004073 issue 215555 for a discussion.
4074
Eric Smitha73fbe72008-02-23 03:09:44 +00004075- Added the future_builtins module, which contains hex() and oct().
4076 These are the PEP 3127 version of these functions, designed to be
4077 compatible with the hex() and oct() builtins from Python 3.0. They
4078 differ slightly in their output formats from the existing, unchanged
4079 Python 2.6 builtins. The expected usage of the future_builtins
4080 module is:
4081 from future_builtins import hex, oct
4082
Eric Smith7ef40bf2008-02-20 23:34:22 +00004083- Issue #1600: Modifed PyOS_ascii_formatd to use at most 2 digit
4084 exponents for exponents with absolute value < 100. Follows C99
4085 standard. This is a change on Windows, which would use 3 digits.
4086 Also, added 'n' to the formats that PyOS_ascii_formatd understands,
4087 so that any alterations it does to the resulting string will be
4088 available in stringlib/formatter.h (for float.__format__).
4089
Eric Smith5a3c1352008-02-19 13:21:56 +00004090- Implemented PEP 3101, Advanced String Formatting. This adds a new
4091 builtin format(); a format() method for str and unicode; a
4092 __format__() method to object, str, unicode, int, long, float, and
4093 datetime; the class string.Formatter; and the C API
4094 PyObject_Format().
4095
Georg Brandl3ee81df2008-05-17 18:14:43 +00004096- Fixed several potential crashes, all caused by specially crafted
4097 __del__ methods exploiting objects in temporarily inconsistent
4098 state.
Amaury Forgeot d'Arc632fad32008-02-16 20:55:24 +00004099
Vinay Sajipb7edfc42008-04-02 21:10:23 +00004100- Issue #2115: Important speedup in setting __slot__ attributes. Also
Georg Brandl3ee81df2008-05-17 18:14:43 +00004101 prevent a possible crash: an Abstract Base Class would try to access
4102 a slot on a registered virtual subclass.
Amaury Forgeot d'Arc60d6c7f2008-02-15 21:22:45 +00004103
Georg Brandl3ee81df2008-05-17 18:14:43 +00004104- Fixed repr() and str() of complex numbers with infinity or nan as
4105 real or imaginary part.
Christian Heimes2f0da532008-02-15 06:57:08 +00004106
Georg Brandl3ee81df2008-05-17 18:14:43 +00004107- Clear all free lists during a gc.collect() of the highest generation
4108 in order to allow pymalloc to free more arenas. Python may give back
4109 memory to the OS earlier.
Christian Heimes3b718a72008-02-14 12:47:33 +00004110
Georg Brandl3ee81df2008-05-17 18:14:43 +00004111- Issue #2045: Fix an infinite recursion triggered when printing a
4112 subclass of collections.defaultdict, if its default_factory is set
4113 to a bound method.
Amaury Forgeot d'Arcb01aa432008-02-08 00:56:02 +00004114
Christian Heimesf75dbef2008-02-08 00:11:31 +00004115- Fixed a minor memory leak in dictobject.c. The content of the free
4116 list was not freed on interpreter shutdown.
4117
Georg Brandl21e99f42010-03-07 15:23:59 +00004118- Limit free list of method and built-in function objects to 256
Georg Brandl3ee81df2008-05-17 18:14:43 +00004119 entries each.
Christian Heimes6075a822008-02-06 12:44:34 +00004120
Georg Brandl3ee81df2008-05-17 18:14:43 +00004121- Patch #1953: Added ``sys._compact_freelists()`` and the C API
4122 functions ``PyInt_CompactFreeList`` and ``PyFloat_CompactFreeList``
Christian Heimes422051a2008-02-04 18:00:12 +00004123 to compact the internal free lists of pre-allocted ints and floats.
4124
Georg Brandl3ee81df2008-05-17 18:14:43 +00004125- Issue #1983: Fixed return type of fork(), fork1() and forkpty()
4126 calls. Python expected the return type int but the fork familie
4127 returns pi_t.
Christian Heimes951cc0f2008-01-31 23:08:23 +00004128
Georg Brandl3ee81df2008-05-17 18:14:43 +00004129- Issue #1678380: Fix a bug that identifies 0j and -0j when they
4130 appear in the same code unit.
Mark Dickinson105be772008-01-31 22:17:37 +00004131
Georg Brandl3ee81df2008-05-17 18:14:43 +00004132- Issue #2025: Add tuple.count() and tuple.index() methods to comply
4133 with the collections.Sequence API.
Raymond Hettinger5b07ebc2008-02-07 00:54:20 +00004134
Georg Brandl3ee81df2008-05-17 18:14:43 +00004135- Patch #1970 by Antoine Pitrou: Speedup unicode whitespace and
4136 linebreak detection
Christian Heimes4d4f2702008-01-30 11:32:37 +00004137
Georg Brandl3ee81df2008-05-17 18:14:43 +00004138- Added ``PyType_ClearCache()`` and ``sys._clear_type_cache`` to clear
4139 the internal lookup cache for ref leak tests.
Christian Heimes908caac2008-01-27 23:34:59 +00004140
Georg Brandl3ee81df2008-05-17 18:14:43 +00004141- Patch #1473257: generator objects gain a gi_code attribute. This is
4142 the same object as the func_code attribute of the function that
4143 produced the generator.
Georg Brandl0cdf9a32008-01-26 14:14:20 +00004144
Georg Brandl3ee81df2008-05-17 18:14:43 +00004145- Issue #1920: "while 0" statements were completely removed by the
4146 compiler, even in the presence of an "else" clause, which is
4147 supposed to be run when the condition is false. Now the compiler
4148 correctly emits bytecode for the "else" suite.
Amaury Forgeot d'Arc31eaafe2008-01-24 22:59:25 +00004149
Guido van Rossumeead05f2008-01-24 18:21:02 +00004150- A few crashers fixed: weakref_in_del.py (issue #1377858);
4151 loosing_dict_ref.py (issue #1303614, test67.py);
4152 borrowed_ref_[34].py (not in tracker).
4153
Vinay Sajipd7cf32e2008-01-24 12:43:33 +00004154- Issue #1069410: The "can't load dll" message box on Windows is
Christian Heimesb2302ba2008-01-23 17:15:06 +00004155 suppressed while an extension is loaded by calling SetErrorMode in
4156 dynload_win.c. The error is still reported properly.
4157
Georg Brandl3ee81df2008-05-17 18:14:43 +00004158- Issue #1915: Python compiles with --enable-unicode=no again. However
Christian Heimes082c9b02008-01-23 14:20:50 +00004159 several extension methods and modules do not work without unicode
4160 support.
4161
Georg Brandl26543b12008-01-21 18:36:51 +00004162- Issue #1882: when compiling code from a string, encoding cookies in the
4163 second line of code were not always recognized correctly.
4164
Georg Brandl14404b62008-01-19 19:27:05 +00004165- Issue #1679: "0x" was taken as a valid integer literal.
4166
Georg Brandl6caad7d2008-01-26 14:19:22 +00004167- Issue #1865: ``bytes`` as an alias for ``str`` and b"" as an alias "" were
Christian Heimes288e89a2008-01-18 18:24:07 +00004168 added.
4169
Christian Heimesc94e2b52008-01-14 04:13:37 +00004170- sys.float_info / PyFloat_GetInfo: The floating point information
4171 object was converted from a dict to a specialized structseq object.
4172
Georg Brandl3ee81df2008-05-17 18:14:43 +00004173- Patch #1816: Added sys.flags structseq. It exposes the status of
4174 most command line arguments and PYTHON* environment variables.
Christian Heimesf31b69f2008-01-14 03:42:48 +00004175
Georg Brandl3ee81df2008-05-17 18:14:43 +00004176- Objects/structseq.c: Implemented new structseq representation. The
4177 patch makes structseqs (e.g. the return value of os.stat) more
4178 readable.
Christian Heimes9c201962008-01-14 03:33:52 +00004179
Georg Brandl3ee81df2008-05-17 18:14:43 +00004180- Patch #1700288: added a type attribute cache that caches method
4181 accesses, resulting in speedups in heavily object-oriented code.
Amaury Forgeot d'Arce4c270c2008-01-14 00:29:41 +00004182
Neal Norwitz3fc15b82008-01-10 05:42:58 +00004183- Bug #1776: __import__() no longer accepts filenames on any platform.
4184 The first parameter to __import__() must be a valid module name.
Christian Heimes3403f152008-01-09 19:56:33 +00004185
Georg Brandlaed6c662008-01-07 17:25:53 +00004186- Patch #1668: renamed THREADDEBUG envvar to PYTHONTHREADDEBUG.
4187
Georg Brandl3ee81df2008-05-17 18:14:43 +00004188- Patch #602345: Add -B command line option, PYTHONDONTWRITEBYTECODE
4189 envvar and sys.dont_write_bytecode attribute. All these can be set
4190 to forbid Python to attempt to write compiled bytecode files.
Georg Brandl2da0fce2008-01-07 17:09:35 +00004191
Georg Brandl3ee81df2008-05-17 18:14:43 +00004192- Improve some exception messages when Windows fails to load an
4193 extension module. Now we get for example '%1 is not a valid Win32
4194 application' instead of 'error code 193'.
Amaury Forgeot d'Arce0b76952008-01-04 02:04:15 +00004195
Georg Brandl3ee81df2008-05-17 18:14:43 +00004196- Bug #1481296: Fixed long(float('nan')) != 0L.

Georg Brandl3ee81df2008-05-17 18:14:43 +00004198- Issue #1640: Added math.isinf(x), math.isnan(x) and math.copysign(x,
4199 y) functions.
Christian Heimese2ca4242008-01-03 20:23:15 +00004200
Christian Heimes0a8143f2007-12-18 23:22:54 +00004201- Issue #1635: Platform independent creation and representation of NaN
Georg Brandl3ee81df2008-05-17 18:14:43 +00004202 and INF. float("nan"), float("inf") and float("-inf") now work on
4203 every platform with IEEE 754 semantics.
Christian Heimes0a8143f2007-12-18 23:22:54 +00004204
Georg Brandl3ee81df2008-05-17 18:14:43 +00004205- Compiler now generates simpler and faster code for dictionary
4206 literals. The oparg for BUILD_MAP now indicates an estimated
4207 dictionary size. There is a new opcode, STORE_MAP, for adding
4208 entries to the dictionary.
Raymond Hettingerfd7ed402007-12-18 21:24:09 +00004209
Georg Brandl3ee81df2008-05-17 18:14:43 +00004210- Issue #1638: %zd configure test fails on Linux.
Christian Heimesdb3d6cb2007-12-16 21:39:43 +00004211
Georg Brandl3ee81df2008-05-17 18:14:43 +00004212- Issue #1620: New property decorator syntax was modifying the

Georg Brandl3ee81df2008-05-17 18:14:43 +00004215- Issue #1538: Avoid copying string in split/rsplit if the split char
4216 is not found.
Skip Montanaro26015492007-12-08 15:33:24 +00004217
Andrew M. Kuchling395fe442007-12-05 13:27:20 +00004218- Issue #1553: An erroneous __length_hint__ can make list() raise a
Christian Heimes7cc1c6f2007-12-05 12:52:34 +00004219 SystemError.
4220
Nick Coghlanef01d822007-12-03 12:55:17 +00004221- PEP 366: Allow explicit relative imports when executing modules
4222 inside packages with the -m switch via a new module level
4223 __package__ attribute.
4224
Georg Brandl3ee81df2008-05-17 18:14:43 +00004225- Issue #1402: Fix a crash on exit, when another thread is still
4226 running, and if the deallocation of its frames somehow calls the
4227 PyGILState_Ensure() / PyGILState_Release() functions.
Amaury Forgeot d'Arcbe49a902007-11-30 20:37:22 +00004228

Amaury Forgeot d'Arcce7d10c2007-11-24 13:44:17 +00004232 attribute of an empty cell object.
4233
Georg Brandl3ee81df2008-05-17 18:14:43 +00004234- Issue #1460: The utf-7 incremental decoder did not accept truncated
4235 input. It now correctly saves its state between chunks of data.
Amaury Forgeot d'Arcf57375a2007-11-21 01:38:26 +00004236
Georg Brandl3ee81df2008-05-17 18:14:43 +00004237- Patch #1739468: Directories and zipfiles containing a __main__.py
4238 file can now be directly executed by passing their name to the
4239 interpreter. The directory/zipfile is automatically inserted as the
4240 first entry in sys.path.
Nick Coghlan327a39b2007-11-18 11:56:28 +00004241
Georg Brandl3ee81df2008-05-17 18:14:43 +00004242- Issue #1265: Fix a problem with sys.settrace, if the tracing
4243 function uses a generator expression when at the same time the
4244 executed code is closing a paused generator.
Amaury Forgeot d'Arc0d75f092007-11-13 21:54:28 +00004245
Raymond Hettinger1760c8a2007-11-08 02:52:43 +00004246- sets and frozensets now have an isdisjoint() method.
4247
Raymond Hettinger3f8caa32007-10-24 01:28:33 +00004248- optimize the performance of builtin.sum().
4249
Neal Norwitz44f326e2007-10-05 05:29:17 +00004250- Fix warnings found by the new version of the Coverity checker.
4251
Georg Brandl21e99f42010-03-07 15:23:59 +00004252- The enumerate() built-in function is no longer bounded to sequences
Georg Brandl3ee81df2008-05-17 18:14:43 +00004253 smaller than LONG_MAX. Formerly, it raised an OverflowError. Now,
4254 automatically shifts from ints to longs.
Raymond Hettinger8f669372007-10-03 21:18:11 +00004255
Georg Brandl3ee81df2008-05-17 18:14:43 +00004256- Issue #1686386: Tuple's tp_repr did not take into account the
4257 possibility of having a self-referential tuple, which is possible
4258 from C code. Nor did object's tp_str consider that a type's tp_str
4259 could do something that could lead to an inifinite recursion.
4260 Py_ReprEnter() and Py_EnterRecursiveCall(), respectively, fixed the
4261 issues.
Brett Cannon0b14f242007-09-30 19:45:10 +00004262
Georg Brandl3ee81df2008-05-17 18:14:43 +00004263- Issue #1164: It was possible to trigger deadlock when using the
4264 'print' statement to write to a file since the GIL was not released
4265 as needed. Now PyObject_Print() does the right thing along with

Georg Brandl3ee81df2008-05-17 18:14:43 +00004269- Issue #1147: Exceptions were directly allowing string exceptions in
4270 their throw() method even though string exceptions no longer
4271 allowed.

Georg Brandl3ee81df2008-05-17 18:14:43 +00004273- Issue #1096: Prevent a segfault from getting the repr of a very
4274 deeply nested list by using the recursion counter.
Brett Cannona0c05512007-09-10 21:38:27 +00004275
Brett Cannon1e534b52007-09-07 04:18:30 +00004276- Issue #1202533: Fix infinite recursion calls triggered by calls to
Georg Brandl3ee81df2008-05-17 18:14:43 +00004277 PyObject_Call() never calling back out to Python code to trigger
4278 recursion depth updates/checks. Required the creation of a static
4279 RuntimeError instance in case normalizing an exception put the
4280 recursion check value past its limit. Fixes crashers
4281 infinite_rec_(1|2|4|5).py.
Brett Cannon1e534b52007-09-07 04:18:30 +00004282

Neal Norwitz0ac60192007-05-27 04:08:54 +00004296- Add new attribute names for function objects. All the func_* become
Georg Brandl3ee81df2008-05-17 18:14:43 +00004297 __*__ attributes. (Some already existed, e.g., __doc__ and
4298 __name__.)
Neal Norwitz0ac60192007-05-27 04:08:54 +00004299
Neal Norwitz8b2bfbc2007-05-23 06:35:32 +00004300- Add -3 option to the interpreter to warn about features that are

4302
Georg Brandl2134e752007-05-21 20:34:16 +00004303- Patch #1686487: you can now pass any mapping after '**' in function
4304 calls.
4305
Collin Winter62903052007-05-18 23:11:24 +00004306- except clauses may now be spelled either "except E, target:" or
Georg Brandl3ee81df2008-05-17 18:14:43 +00004307 "except E as target:". This is to provide forwards compatibility
4308 with Python 3.0.
Collin Winter62903052007-05-18 23:11:24 +00004309
Brett Cannon229cee22007-05-05 01:34:02 +00004310- Deprecate BaseException.message as per PEP 352.
4311
Georg Brandl3ee81df2008-05-17 18:14:43 +00004312- Issue #1303614: don't expose object's __dict__ when the dict is
Georg Brandl21e99f42010-03-07 15:23:59 +00004313 inherited from a built-in base.

Vinay Sajip8549ce32007-05-06 17:53:37 +00004315- When __slots__ are set to a unicode string, make it work the same as
Neal Norwitzcbd9ee62007-04-14 05:25:50 +00004316 setting a plain string, ie don't expand to single letter identifiers.
4317
Raymond Hettinger13936692007-04-11 18:40:58 +00004318- Request #1191699: Slices can now be pickled.
4319
Raymond Hettinger4db5fe92007-04-12 04:10:00 +00004320- Request #1193128: str.translate() now allows a None argument for
4321 translations that only remove characters without re-mapping the
4322 remaining characters.
4323
Georg Brandl5cb76c12007-03-21 09:00:39 +00004324- Patch #1682205: a TypeError while unpacking an iterable is no longer
4325 masked by a generic one with the message "unpack non-sequence".
4326
Neal Norwitzaa754b72007-03-21 06:39:48 +00004327- Remove unused file Python/fmod.c.
4328
Guido van Rossum143b5642007-03-23 04:58:42 +00004329- Bug #1683368: The object.__init__() and object.__new__() methods are
4330 now stricter in rejecting excess arguments. The only time when
4331 either allows excess arguments is when it is not overridden and the
4332 other one is. For backwards compatibility, when both are
4333 overridden, it is a deprecation warning (for now; maybe a Py3k
Guido van Rossum234b1ff2007-03-23 19:39:01 +00004334 warning later). Also, type.__init__() insists on the same signature
4335 as supported by type.__new__().
Guido van Rossum143b5642007-03-23 04:58:42 +00004336
Georg Brandl3ee81df2008-05-17 18:14:43 +00004337- Patch #1675423: PyComplex_AsCComplex() now tries to convert an
4338 object to complex using its __complex__() method before falling back
4339 to the __float__() method. Therefore, the functions in the cmath
4340 module now can operate on objects that define a __complex__()
4341 method.
Georg Brandl2b869942007-03-17 16:08:45 +00004342
Georg Brandl3ee81df2008-05-17 18:14:43 +00004343- Patch #1623563: allow __class__ assignment for classes with
4344 __slots__. The old and the new class are still required to have the
4345 same slot names.
Žiga Seilnacht6f2d09c2007-03-16 11:59:38 +00004346

4351 ``object.__reduce_ex__()`` is called with an object that is faking
4352 its type.
Žiga Seilnacht20f43d32007-03-15 11:44:55 +00004353
Georg Brandl3ee81df2008-05-17 18:14:43 +00004354- Patch #1680015: Don't modify __slots__ tuple if it contains an

4358
Georg Brandl7b9c5552007-03-12 14:30:05 +00004359- Bug #1678647: write a newline after printing an exception in any
4360 case, even when converting the value to a string failed.
4361
Georg Brandl871f1bc2007-03-12 13:17:36 +00004362- The dir() function has been extended to call the __dir__() method on
Georg Brandl3ee81df2008-05-17 18:14:43 +00004363 its argument, if it exists. If not, it will work like before. This
4364 allows customizing the output of dir() in the presence of a
4365 __getattr__().
Georg Brandl871f1bc2007-03-12 13:17:36 +00004366
Collin Winter276887b2007-03-12 16:11:39 +00004367- Patch #922167: Python no longer segfaults when faced with infinitely
4368 self-recursive reload() calls (as reported by bug #742342).
4369

4374 parthensized forms. This means complex(repr(x)) now works instead of
4375 raising a ValueError.
Collin Wintere38051d2007-03-09 20:33:07 +00004376
Georg Brandlaa2321b2007-03-07 00:40:28 +00004377- Patch #703779: unset __file__ in __main__ after running a file. This
Georg Brandl3ee81df2008-05-17 18:14:43 +00004378 makes the filenames the warning module prints much more sensible
4379 when a PYTHONSTARTUP file is used.
Georg Brandlaa2321b2007-03-07 00:40:28 +00004380
Georg Brandl49aafc92007-03-07 00:34:46 +00004381- Variant of patch #697613: don't exit the interpreter on a SystemExit
4382 exception if the -i command line option or PYTHONINSPECT environment
Georg Brandl3ee81df2008-05-17 18:14:43 +00004383 variable is given, but break into the interactive interpreter just
4384 like on other exceptions or normal program exit.

4390 condition.
Georg Brandl098cd692007-03-06 12:17:50 +00004391
Georg Brandl0fca97a2007-03-05 22:28:08 +00004392- Patch #1674228: when assigning a slice (old-style), check for the
4393 sq_ass_slice instead of the sq_slice slot.
4394
Georg Brandl3ee81df2008-05-17 18:14:43 +00004395- When printing an unraisable error, don't print exceptions. before
4396 the name. This duplicates the behavior whening normally printing
4397 exceptions.

4406 created a weakref on itself during a __del__ call for new-style
4407 classes (classic classes still have the bug).

5006 Python would crash instead of raising an error.
5007

5020
Georg Brandl3ee81df2008-05-17 18:14:43 +00005021- unittest now verifies more of its assumptions. In particular,

5023 accepted in TestSuite.addTest(). This should cause no
5024 incompatibility since it never made sense with ordinary subclasses
5025 -- the failure just occurred later, with a more cumbersome
5026 exception.

Gregory P. Smith2b3ba582008-01-17 08:03:17 +00005311
Georg Brandl3ee81df2008-05-17 18:14:43 +00005312- Issue #1339: The smtplib.SMTP class has been refactored a bit such
Gregory P. Smithbde4ae42008-01-17 08:35:49 +00005313 that the SMTP.starttls() caller no longer needs to call ehlo()
5314 beforehand. SMTP.starttls() now raises an exception of the server
Georg Brandl3ee81df2008-05-17 18:14:43 +00005315 does not claim to support starttls. Adds the
5316 SMTP.ehlo_or_helo_if_needed() method. Patch contributed by Bill

Georg Brandl3ee81df2008-05-17 18:14:43 +00005415 time so that opening a database previously created with the DB_DUP
5416 or DB_DUPSORT flag set will keep the proper behavior on subsequent
5417 opens. Specifically: dictionary assignment to a DB object will
5418 replace all values for a given key when the database allows
5419 duplicate values. DB users should use DB.put(k, v) when they want
5420 to store duplicates; not DB[k] = v.

5427 characters with ASCII value less than 32. Also, it correctly quotes
5428 dots only if they occur on a single line, as opposed to the previous
5429 behavior of quoting dots if they are the second character of any
5430 line.

5753-----
5754
Georg Brandl3ee81df2008-05-17 18:14:43 +00005755- Unified naming convention for free lists and their limits. All free
5756 lists in Object/ are named ``free_list``, the counter ``numfree``
5757 and the upper limit is a macro ``PyName_MAXFREELIST`` inside an
5758 #ifndef block.
Christian Heimes5b970ad2008-02-06 13:33:44 +00005759
Georg Brandl3ee81df2008-05-17 18:14:43 +00005760- ``PySet_Add()`` can now modify a newly created frozenset. Similarly
5761 to ``PyTuple_SetItem``, it can be used to populate a brand new
5762 frozenset; but it does not steal a reference to the added item.
Amaury Forgeot d'Arccab3d982008-02-03 22:51:43 +00005763
Vinay Sajipb7edfc42008-04-02 21:10:23 +00005764- Added ``PySet_Check()`` and ``PyFrozenSet_Check()`` to the set API.

Georg Brandl3ee81df2008-05-17 18:14:43 +00005766- Backport of PyUnicode_FromString(), _FromStringAndSize(), _Format
5767 and _FormatV from Python 3.0. Made PyLong_AsSsize_t and
5768 PyLong_FromSsize_t public functions.
Georg Brandl6caad7d2008-01-26 14:19:22 +00005769
5770- Patch #1720595: add T_BOOL to the range of structmember types.
5771
5772- Issue #1534: Added ``PyFloat_GetMax()``, ``PyFloat_GetMin()`` and
5773 ``PyFloat_GetInfo()`` to the float API.
5774
Georg Brandl3ee81df2008-05-17 18:14:43 +00005775- Issue #1521: On 64bit platforms, using PyArgs_ParseTuple with the t#
5776 of w# format code incorrectly truncated the length to an int, even
5777 when PY_SSIZE_T_CLEAN is set. The str.decode method used to return
5778 incorrect results with huge strings.
Georg Brandl6caad7d2008-01-26 14:19:22 +00005779
Georg Brandl3ee81df2008-05-17 18:14:43 +00005780- Issue #1629: Renamed Py_Size, Py_Type and Py_Refcnt to Py_SIZE,
5781 Py_TYPE and Py_REFCNT.
Georg Brandl6caad7d2008-01-26 14:19:22 +00005782
Georg Brandl3ee81df2008-05-17 18:14:43 +00005783- PEP 3123: Provide forward compatibility with Python 3.0, while
5784 keeping backwards compatibility. Add Py_Refcnt, Py_Type, Py_Size,
5785 and PyVarObject_HEAD_INIT.
Georg Brandl6caad7d2008-01-26 14:19:22 +00005786
Georg Brandl3ee81df2008-05-17 18:14:43 +00005787- Py_ssize_t fields work in structmember when HAVE_LONG_LONG is not
5788 defined.
Georg Brandl6caad7d2008-01-26 14:19:22 +00005789
5790- Patch #1733960: Allow T_LONGLONG to accept ints.
5791
5792- T_PYSSIZET can now be used in PyMemberDef lists for Py_ssize_t members.
5793

5797
5798- Fix some leftovers from the conversion from int to Py_ssize_t
5799 (relevant to strings and sequences of more than 2**31 items).
5800
5801- Make _PyGILState_NoteThreadState() static, it was not used anywhere
5802 outside of pystate.c and should not be necessary.
5803
Georg Brandl3ee81df2008-05-17 18:14:43 +00005804- ``PyImport_Import`` and ``PyImport_ImportModule`` now always do
5805 absolute imports. In earlier versions they might have used relative
5806 imports under some conditions.
Christian Heimes000a0742008-01-03 22:16:32 +00005807
Georg Brandl3ee81df2008-05-17 18:14:43 +00005808- Added case insensitive comparison methods ``PyOS_stricmp(char*,
5809 char*)`` and ``PyOS_strnicmp(char*, char*, Py_ssize_t)``.
Christian Heimes000a0742008-01-03 22:16:32 +00005810
Georg Brandl3ee81df2008-05-17 18:14:43 +00005811- Bug #1542693: remove semi-colon at end of PyImport_ImportModuleEx
5812 macro so it can be used as an expression.

5817
Georg Brandl3ee81df2008-05-17 18:14:43 +00005818- Patch #1706: Drop support for Win9x, WinME and NT4. Python now
5819 requires Windows 2000 or greater. The _WINVER and NTDDI_VERSION
5820 macros are set to Win2k for x86/32bit builds and WinXP for AMD64
5821 builds.
Christian Heimes95d64472008-02-09 19:55:22 +00005822
Georg Brandl3ee81df2008-05-17 18:14:43 +00005823- Conditionalize definition of _CRT_SECURE_NO_DEPRECATE and

Georg Brandl3ee81df2008-05-17 18:14:43 +00005836- Removed the macfs module. It had been deprecated since Python 2.5.
5837 This lead to the deprecation of macostools.touched() as it relied
5838 solely on macfs and was a no-op under OS X.
