56 indefinitely if the other end didn't respond.
57
Antoine Pitrou4d3e3722010-04-24 19:57:01 +000058- The do_handshake() method of SSL objects now adjusts the blocking mode of

102
R. David Murray1a14d3d2010-04-12 16:35:19 +0000103- Issue #7585: difflib context and unified diffs now place a tab between
104 filename and date, conforming to the 'standards' they were originally
105 designed to follow. This improves compatibility with patch tools.
106
R. David Murray27ef9372010-04-12 14:26:06 +0000107- Issue #7472: Fixed typo in email.encoders module; messages using ISO-2022

Benjamin Peterson5da7e7c2010-03-06 22:44:07 +0000140
141Core and Builtins
142-----------------
143
Philip Jenveyaebbaeb2010-04-06 23:24:45 +0000144- Issue #7301: Add environment variable $PYTHONWARNINGS.
145
Benjamin Peterson3a1dfa22010-04-06 21:50:00 +0000146- Issue #8329: Don't return the same lists from select.select when no fds are
147 changed.
148
Mark Dickinson82791672010-04-06 16:47:55 +0000149- Issue #8259: 1L << (2**31) no longer produces an 'outrageous shift error'
150 on 64-bit machines. The shift count for either left or right shift is
151 permitted to be up to sys.maxsize.
152
Benjamin Peterson4ceeeb02010-04-03 22:48:51 +0000153- Ensure that tokenization of identifiers is not affected by locale.

158
Eric Smithd44b2fc2010-04-02 12:30:56 +0000159- Issue #7994: Issue a PendingDeprecationWarning if object.__format__
160 is called with a non-empty format string. This is an effort to
161 future-proof user code. If a derived class does not currently
162 implement __format__ but later adds its own __format__, it would
163 most likely break user code that had supplied a format string. This
164 will be changed to a DeprecationWaring in Python 3.3 and it will be
165 an error in Python 3.4.
166
Antoine Pitroua57df2c2010-03-31 21:32:15 +0000167- Issue #8268: Old-style classes (not just instances) now support weak
168 references.

Georg Brandlba83f822010-03-14 09:50:54 +0000181 (SIGINT). If an error occurs while importing the site module, the error is
182 printed and Python exits. Initialize the GIL before importing the site
Victor Stinner66644262010-03-10 22:30:19 +0000183 module.
184
Collin Winter001a3952010-03-18 21:54:01 +0000185- Code objects now support weak references.

191
Antoine Pitrouf9de5342010-04-05 21:35:07 +0000192- Issue #8321: Give access to OpenSSL version numbers from the `ssl` module,
193 using the new attributes `ssl.OPENSSL_VERSION`, `ssl.OPENSSL_VERSION_INFO`
194 and `ssl.OPENSSL_VERSION_NUMBER`.
195
Benjamin Peterson76a23c12010-04-04 23:23:22 +0000196- Issue #8310: Allow dis to examine new style classes.
197
Mark Dickinson8a950712010-04-03 15:47:46 +0000198- Issue #8257: The Decimal construct now accepts a float instance
199 directly, converting that float to a Decimal of equal value:
200
201 >>> Decimal(1.1)

205
Raymond Hettingera551f312010-04-04 18:34:45 +0000206- the functools module now has a total_ordering() class decorator
Georg Brandl4fabac52010-04-14 08:53:38 +0000207 to simplify the specification of rich comparisons.
Raymond Hettingera551f312010-04-04 18:34:45 +0000208
Raymond Hettingerbb006cf2010-04-04 21:45:01 +0000209- The functools module also adds cmp_to_key() as a tool to transition
Raymond Hettingera551f312010-04-04 18:34:45 +0000210 old-style comparison functions to new-style key-functions.
211
Mark Dickinson7c63eee2010-04-02 22:27:36 +0000212- Issue #8294: The Fraction constructor now accepts Decimal and float
213 instances directly.
214
Mark Dickinsone096e822010-04-02 10:17:07 +0000215- Issue #7279: Comparisons involving a Decimal signaling NaN now
216 signal InvalidOperation instead of returning False. (Comparisons
Mark Dickinsonf3eeca12010-04-02 10:35:12 +0000217 involving a quiet NaN are unchanged.) Also, Decimal quiet NaNs
218 are now hashable; Decimal signaling NaNs remain unhashable.
Mark Dickinsone096e822010-04-02 10:17:07 +0000219
Mark Dickinson99d80962010-04-02 08:53:22 +0000220- Issue #2531: Comparison operations between floats and Decimal
221 instances now return a result based on the numeric values of the

Barry Warsawf7f2d6f2010-03-31 21:07:16 +0000225- Issue #8233: When run as a script, py_compile.py optionally takes a single
226 argument `-` which tells it to read files to compile from stdin. Each line
227 is read on demand and the named file is compiled immediately. (Original
228 patch by Piotr Ożarowski).
229
230- Issue #3135: Add inspect.getcallargs, which binds arguments to a function
231 like a normal call.
Benjamin Peterson7e213252010-03-30 17:58:13 +0000232
Florent Xicluna58b65662010-03-30 16:29:03 +0000233- Backwards incompatible change: Unicode codepoints line tabulation (0x0B) and
234 form feed (0x0C) are now considered linebreaks, as specified in Unicode
235 Standard Annex #14. See issue #7643.
Florent Xicluna22b24382010-03-30 08:24:06 +0000236 http://www.unicode.org/reports/tr14/
237
Mark Dickinson9588d992010-03-27 11:14:37 +0000238- Comparisons using one of <, <=, >, >= between a complex instance and
239 a Fractions instance now raise TypeError instead of returning
240 True/False. This makes Fraction <=> complex comparisons consistent with
241 int <=> complex, float <=> complex, and complex <=> complex comparisons.
242
Michael Foorde6410c52010-03-29 20:04:23 +0000243- Addition of ``WeakSet`` to the ``weakref`` module.

341 integer format code, struct.pack first attempts to convert the non-integer

343 TypeError it goes on to try the __int__ method, as described below.

Georg Brandlba83f822010-03-14 09:50:54 +0000345- Issue #1530559: When passing a non-integer argument to struct.pack with *any*
346 integer format code (one of 'bBhHiIlLqQ'), struct.pack attempts to use the
347 argument's __int__ method to convert to an integer before packing. It also
348 produces a DeprecationWarning in this case. (In Python 2.6, the behaviour
349 was inconsistent: __int__ was used for some integer codes but not for others,
350 and the set of integer codes for which it was used differed between native
351 packing and standard packing.)

576 and read operations on write-only file objects. On Windows, the system C
Georg Brandlba83f822010-03-14 09:50:54 +0000577 library would return a bogus result; on Solaris, it was possible to crash the

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

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

Antoine Pitroud840e512010-02-04 20:20:18 +0000641- Issue #4772: Raise a ValueError when an unknown Bluetooth protocol is
Georg Brandlba83f822010-03-14 09:50:54 +0000642 specified, rather than fall through to AF_PACKET (in the ``socket`` module).
Antoine Pitroud840e512010-02-04 20:20:18 +0000643 Also, raise ValueError rather than TypeError when an unknown TIPC address

Antoine Pitrouf3fa0742010-01-31 22:26:04 +0000648- Issue #6939: Fix file I/O objects in the `io` module to keep the original
Georg Brandlba83f822010-03-14 09:50:54 +0000649 file position when calling `truncate()`. It would previously change the file
650 position to the given argument, which goes against the tradition of
Antoine Pitrouf3fa0742010-01-31 22:26:04 +0000651 ftruncate() and other truncation APIs. Patch by Pascal Chambon.
652
Benjamin Petersone06f7112010-01-28 02:15:02 +0000653- UserDict is now a new-style class.
654
Georg Brandlba83f822010-03-14 09:50:54 +0000655- Issue #7610: Reworked implementation of the internal ``zipfile.ZipExtFile``
656 class used to represent files stored inside an archive. The new
657 implementation is significantly faster and can be wrapped in a
658 ``io.BufferedReader`` object for more speedups. It also solves an issue
659 where interleaved calls to ``read()`` and ``readline()`` give wrong results.
660 Patch by Nir Aides.

Benjamin Petersona43f34c2010-01-25 03:31:13 +0000669
Georg Brandlba83f822010-03-14 09:50:54 +0000670- Issue #7748: Since unicode values are supported for some metadata options in
671 Distutils, the DistributionMetadata get_* methods will now return an utf-8
672 encoded string for them. This ensures that the upload and register commands
673 send the correct values to PyPI without any error.

747Core and Builtins
748-----------------
749
Georg Brandlba83f822010-03-14 09:50:54 +0000750- The ``__complex__()`` method is now looked up on the class of instances to
751 make it consistent with other special methods.
Benjamin Petersonecdae192010-01-04 00:43:01 +0000752
Antoine Pitrou5b7139a2010-01-02 21:12:58 +0000753- Issue #7462: Implement the stringlib fast search algorithm for the `rfind`,
754 `rindex`, `rsplit` and `rpartition` methods. Patch by Florent Xicluna.
755
Mark Dickinson1b34d252010-01-01 17:27:30 +0000756- Issue #5080: A number of functions and methods previously produced a
Georg Brandlba83f822010-03-14 09:50:54 +0000757 DeprecationWarning when passed a float argument where an integer was expected.
758 These functions and methods now raise TypeError instead. The majority of the
759 effects of this change are in the extension modules, but some core functions
760 and methods are affected: notably the 'chr', 'range' and 'xrange' builtins,
761 and many unicode/str methods.

Georg Brandlba83f822010-03-14 09:50:54 +0000774- Issue #1811: Improve accuracy and cross-platform consistency for true division
775 of integers: the result of a/b is now correctly rounded for ints a and b (at
776 least on IEEE 754 platforms), and in particular does not depend on the
777 internal representation of a long.

Georg Brandlba83f822010-03-14 09:50:54 +0000779- Issue #6108: ``unicode(exception)`` and ``str(exception)`` should return the
780 same message when only ``__str__()`` (and not ``__unicode__()``) is overridden
781 in the subclass.

785
Georg Brandlba83f822010-03-14 09:50:54 +0000786 These executables now work properly with the arch(1) command: ``arch -ppc
787 python`` will start a universal binary version of python in PPC mode (unlike
788 previous releases).

Ronald Oussoren315cd0c2009-11-19 16:25:21 +0000943
Georg Brandlba83f822010-03-14 09:50:54 +0000944- Issue #7117: ``repr(x)`` for a float x returns a result based on the shortest
945 decimal string that's guaranteed to round back to x under correct rounding
946 (with round-half-to-even rounding mode). Previously it gave a string based on
947 rounding x to 17 decimal digits. repr(x) for a complex number behaves
948 similarly. On platforms where the correctly-rounded strtod and dtoa code is
949 not supported (see below), repr is unchanged.
Mark Dickinsonb678de82009-11-19 18:41:49 +0000950
Georg Brandlba83f822010-03-14 09:50:54 +0000951- Issue #7117: On almost all platforms: float-to-string and string-to-float
952 conversions within Python are now correctly rounded. Places these conversions
953 occur include: str for floats and complex numbers; the float and complex
954 constructors; old-style and new-style numeric formatting; serialization and
955 deserialization of floats and complex numbers using marshal, pickle and json;
956 parsing of float and imaginary literals in Python code; Decimal-to-float
957 conversion.
Mark Dickinsonb678de82009-11-19 18:41:49 +0000958
Georg Brandlba83f822010-03-14 09:50:54 +0000959 The conversions use a Python-adapted version of David Gay's well-known dtoa.c,
960 providing correctly-rounded strtod and dtoa C functions. This code is
961 supported on Windows, and on Unix-like platforms using gcc, icc or suncc as
962 the C compiler. There may be a small number of platforms on which correct
963 operation of this code cannot be guaranteed, so the code is not used: notably,
964 this applies to platforms where the C double format is not IEEE 754 binary64,
965 and to platforms on x86 hardware where the x87 FPU is set to 64-bit precision
966 and Python's configure script is unable to determine how to change the FPU
967 precision. On these platforms conversions use the platform strtod and dtoa,
968 as before.

Georg Brandlba83f822010-03-14 09:50:54 +0000970- Issue #7117: Backport round implementation from Python 3.x. ``round()`` now
971 uses the correctly-rounded string <-> float conversions described above (when
972 available), and so produces correctly rounded results that will display nicely
973 under the float repr. There are two related small changes: (1) round now
974 accepts any class with an ``__index__()`` method for its second argument (but
975 no longer accepts floats for the second argument), and (2) an excessively
976 large second integer argument (e.g., ``round(1.234, 10**100)``) no longer
977 raises an exception.

Georg Brandlba83f822010-03-14 09:50:54 +00001120 (1) inf and nan strings with trailing whitespace were incorrectly rejected;
1121 (2) parsing of strings representing infinities and nans was locale aware; and
1122 (3) the interpretation of fromhex('-nan') didn't match that of float('-nan').

Georg Brandlba83f822010-03-14 09:50:54 +00001124- Issue #5920: For ``float.__format__()``, change the behavior with the empty
1125 presentation type (that is, not one of 'e', 'f', 'g', or 'n') to be like 'g'
1126 but with at least one decimal point and with a default precision
1127 of 12. Previously, the behavior the same but with a default precision of 6.
1128 This more closely matches ``str()``, and reduces surprises when adding
1129 alignment flags to the empty presentation type. This also affects the new
1130 complex.__format__ in the same way.
1131
1132- Issue #5890: In subclasses of 'property' the __doc__ attribute was shadowed by

1269
Georg Brandlba83f822010-03-14 09:50:54 +00001270- Issue #1180193: When importing a module from a .pyc (or .pyo) file with an
1271 existing .py counterpart, override the co_filename attributes of all code
1272 objects if the original filename is obsolete (which can happen if the file has
1273 been renamed, moved, or if it is accessed through different paths). Patch by
1274 Ziga Seilnacht and Jean-Paul Calderone.

Hirokazu Yamamoto99a1b202009-01-01 15:45:39 +00001278- Issue #4797: IOError.filename was not set when _fileio.FileIO failed to open
1279 file with `str' filename on Windows.
1280
Antoine Pitrouaa687902009-01-01 14:11:22 +00001281- Issue #3680: Reference cycles created through a dict, set or deque iterator
1282 did not get collected.
1283
Georg Brandlba83f822010-03-14 09:50:54 +00001284- Issue #4701: PyObject_Hash now implicitly calls PyType_Ready on types where

Benjamin Peterson7af65562008-12-29 17:56:58 +00001287- Issue #4764: With io.open, IOError.filename is set when trying to open a
1288 directory on POSIX systems.
1289
Benjamin Petersonfe231b02008-12-29 17:47:42 +00001290- Issue #4764: IOError.filename is set when trying to open a directory on POSIX
1291 systems.
1292
Georg Brandl6425a2f2008-12-28 11:54:53 +00001293- Issue #4759: None is now allowed as the first argument of
Georg Brandlba83f822010-03-14 09:50:54 +00001294 ``bytearray.translate()``. It was always allowed for ``bytes.translate()``.
Georg Brandl6425a2f2008-12-28 11:54:53 +00001295
Skip Montanarof205c132008-12-23 03:30:15 +00001296- Added test case to ensure attempts to read from a file opened for writing
1297 fail.
1298
Georg Brandlba83f822010-03-14 09:50:54 +00001299- Issue #2467: gc.DEBUG_STATS reported invalid elapsed times. Also, always print
1300 elapsed times, not only when some objects are uncollectable/unreachable.
1301 Original patch by Neil Schemenauer.

Georg Brandlba83f822010-03-14 09:50:54 +00001313- Issue #4445: Replace ``sizeof(PyStringObject)`` with
1314 ``offsetof(PyStringObject, ob_sval) + 1`` when allocating memory for str
1315 instances. On a typical machine this saves 3 bytes of memory (on average) per
1316 string allocation.
Mark Dickinson826f3fe2008-12-05 21:55:28 +00001317
Amaury Forgeot d'Arcdc619012008-11-22 20:01:18 +00001318- Issue #3996: On Windows, the PyOS_CheckStack function would cause the
1319 interpreter to abort ("Fatal Python error: Could not reset the stack!")
1320 instead of throwing a MemoryError.
1321
Georg Brandlba83f822010-03-14 09:50:54 +00001322- Issue #3689: The list reversed iterator now supports __length_hint__ instead
1323 of __len__. Behavior now matches other reversed iterators.
Raymond Hettinger7989a4d2008-12-03 15:42:10 +00001324
Benjamin Petersonc078f922008-11-21 22:27:24 +00001325- Issue #4367: Python would segfault during compiling when the unicodedata
1326 module couldn't be imported and \N escapes were present.
1327
Georg Brandlba83f822010-03-14 09:50:54 +00001328- Issue #4233: Changed semantic of ``_fileio.FileIO``'s ``close()`` method on
1329 file objects with closefd=False. The file descriptor is still kept open but
1330 the file object behaves like a closed file. The ``FileIO`` object also got a
1331 new readonly attribute ``closefd``.
Amaury Forgeot d'Arc32265652008-11-20 23:34:31 +00001332
Benjamin Peterson46cc6d12008-11-19 21:49:09 +00001333- Issue #4348: Some bytearray methods returned that didn't cause any change to
1334 the bytearray, returned the same bytearray instead of a copy.
1335
Georg Brandlba83f822010-03-14 09:50:54 +00001336- Issue #4317: Fixed a crash in the ``imageop.rgb2rgb8()`` function.

Benjamin Peterson273c2332008-11-17 22:39:09 +00001338- Issue #4230: If ``__getattr__`` is a descriptor, it now functions correctly.
1339
Benjamin Peterson6624a9f2008-11-03 15:14:51 +00001340- Issue #4048: The parser module now correctly validates relative imports.
1341
Benjamin Petersondcee09d2008-10-31 02:16:05 +00001342- Issue #4225: ``from __future__ import unicode_literals`` didn't work in an
1343 exec statement.
1344
Georg Brandlba83f822010-03-14 09:50:54 +00001345- Issue #4176: Fixed a crash when pickling an object which ``__reduce__`` method
1346 does not return iterators for the 4th and 5th items.
Amaury Forgeot d'Arc69a9c5b2008-10-30 21:18:34 +00001347
Benjamin Petersonbdca9422008-10-26 20:21:13 +00001348- Issue #4209: Enabling unicode_literals and the print_function in the same
1349 __future__ import didn't work.
1350
Benjamin Peterson399b1fe2008-10-25 02:53:28 +00001351- Using ``nonlocal`` as a variable name will now raise a Py3k SyntaxWarning
Georg Brandl7fb00ad2008-10-25 07:00:52 +00001352 because it is a reserved word in 3.x.
Benjamin Peterson399b1fe2008-10-25 02:53:28 +00001353
Georg Brandlba83f822010-03-14 09:50:54 +00001354- On windows, ``os.chdir()`` given unicode was not working if
1355 GetCurrentDirectoryW returned a path longer than MAX_PATH. (But It's doubtful
1356 this code path is really executed because I cannot move to such directory on
1357 win2k)
Hirokazu Yamamoto10a018c2008-10-09 10:00:30 +00001358
Georg Brandlba83f822010-03-14 09:50:54 +00001359- Issue #4069: When ``set.remove(element)`` is used with a set element, the
1360 element is temporarily replaced with an equivalent frozenset. But the
1361 eventual KeyError would always report the empty ``frozenset()`` as the missing
1362 key. Now it correctly refers to the initial element.

Georg Brandlba83f822010-03-14 09:50:54 +00001364- Issue #4509: Various issues surrounding resize of bytearray objects to which

1370
Gregory P. Smithae91d092009-03-02 05:13:57 +00001371- The re.sub(), re.subn() and re.split() functions now accept a flags parameter.
1372
Georg Brandlba83f822010-03-14 09:50:54 +00001373- Issue #3845: In PyRun_SimpleFileExFlags avoid invalid memory access with short

Matthias Klose91a3b9e2009-04-05 21:19:13 +00001376- Issue #1113244: Py_XINCREF, Py_DECREF, Py_XDECREF: Add `do { ... } while (0)'
1377 to avoid compiler warnings.

Gregory P. Smith2b3eb372009-04-05 23:48:26 +00001379- Issue #5705: os.setuid() would not accept values > 2**31-1 but pwd.getpwnam()
1380 returned them on 64bit platforms.
1381
Walter Dörwalded960ac2009-05-03 22:36:33 +00001382- Issue #5108: Handle %s like %S and %R in PyUnicode_FromFormatV(): Call
1383 PyUnicode_DecodeUTF8() once, remember the result and output it in a second
1384 step. This avoids problems with counting UTF-8 bytes that ignores the effect
1385 of using the replace error handler in PyUnicode_DecodeUTF8().
1386
Walter Dörwald726ba8e2009-05-06 14:32:35 +00001387- Issue #3739: The unicode-internal encoder now reports the number of characters
1388 consumed like any other encoder (instead of the number of bytes).
1389
Georg Brandlba83f822010-03-14 09:50:54 +00001390- Issue #2422: When compiled with the ``--with-valgrind`` option, the pymalloc
1391 allocator will be automatically disabled when running under Valgrind. This
1392 gives improved memory leak detection when running under Valgrind, while taking
1393 advantage of pymalloc at other times.

Guilherme Polo7f146ab2009-06-21 17:22:50 +00002635- Issue #5450: Moved tests involving loading tk from Lib/test/test_tcl to
2636 Lib/lib-tk/test/test_tkinter/test_loadtk. With this, these tests demonstrate
Georg Brandlba83f822010-03-14 09:50:54 +00002637 the same behaviour as test_ttkguionly (and now also test_tk) which is to skip
2638 the tests if DISPLAY is defined but can't be used.

2644 import both normal and optimised versions of modules. test_heapq and
2645 test_warnings have been adjusted to use it, tests for other modules with both
2646 C and Python implementations in the stdlib can be adjusted to use it over
2647 time.

2656 should cause a test to be skipped are now done using import_module from test
2657 support, which does the conversion.

Martin v. Löwis9fa5a282008-09-11 06:53:30 +00002758- Issue #3642: Suppress warning in obmalloc when size_t is larger than uint.
2759
Amaury Forgeot d'Arc05e34492008-09-10 22:04:45 +00002760- Issue #3743: In a few places, PY_FORMAT_SIZE_T was incorrectly used with
2761 PyString_FromFormat or PyErr_Format to display size_t values. The macro
2762 PY_FORMAT_SIZE_T is designed to select the correct format for the OS
2763 ``printf`` function, whereas PyString_FromFormat has an independent
2764 implementation and uses "%zd" on all platforms for size_t values.
2765 This makes a difference on win64, where ``printf`` needs "%Id" to display
2766 64bit values.

Benjamin Peterson97179b02008-09-09 20:55:01 +00002768- Issue #3634: _weakref.ref(Exception).__init__() gave invalid return value on

2772 object; previously an int would be returned for small values. the __long__

Vinay Sajip35e3b032008-09-01 14:33:59 +00002782 PyArg_ParseTuple and friends, which occurred when the argument for "s*"
Antoine Pitroud4ae97b2008-08-29 18:39:48 +00002783 was correctly parsed but parsing of subsequent arguments failed.
2784
Vinay Sajip35e3b032008-09-01 14:33:59 +00002785- Issue #2534: speed up isinstance() and issubclass() by 50-70%, so as to
Antoine Pitrou0668c622008-08-26 22:42:08 +00002786 match Python 2.5 speed despite the __instancecheck__ / __subclasscheck__
2787 mechanism. In the process, fix a bug where isinstance() and issubclass(),
2788 when given a tuple of classes as second argument, were looking up
2789 __instancecheck__ / __subclasscheck__ on the tuple rather than on each
2790 type object.
2791
Neal Norwitz18aa3882008-08-24 05:04:52 +00002792- Fix crashes on memory allocation failure found with failmalloc.

Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00002929What's New in Python 2.6 beta 3?
2930================================
2931
Barry Warsaw07a4a382008-08-21 01:15:08 +00002932*Release date: 20-Aug-2008*
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00002933
2934Core and Builtins
2935-----------------
2936
Guido van Rossumf8402962008-08-20 15:01:50 +00002937- Issue #1878: Remove Py_TPFLAGS_HAVE_VERSION_TAG from
2938 Py_TPFLAGS_DEFAULT when not building the core. This means 3rd party
2939 extensions do not automatically benefit from the class attribute
2940 cache; they will have to explicitly add Py_TPFLAGS_HAVE_VERSION_TAG
2941 to their tp_flags field if they care. This is a backwards
2942 compatibility feature; in 3.0, all types will use the cache by
2943 default.
2944
Benjamin Petersonf647dc12008-08-20 01:27:30 +00002945- Keyword arguments can now follow starred arguments. (``f(a, *args,
2946 keyword=23)`` is now valid syntax.)
2947
Thomas Heller0ad5ae02008-08-19 19:25:04 +00002948- ctypes function pointers that are COM methods have a boolean True
2949 value again.
2950
Martin v. Löwisf91d46a2008-08-12 14:49:50 +00002951- Issue #3139: Make buffer-interface thread-safe wrt. PyArg_ParseTuple,
2952 by denying s# to parse objects that have a releasebuffer procedure,
2953 and introducing s*.
2954
Georg Brandl1e13ea92008-08-11 09:07:59 +00002955- Issue #3537: Fix an assertion failure when an empty but presized dict
2956 object was stored in the freelist.
2957
Mark Dickinsonb6467572008-08-04 21:30:09 +00002958- Issue #1481296: Make long(float('nan')) and int(float('nan')) raise
2959 ValueError consistently across platforms.
2960
Amaury Forgeot d'Arc39fd6722008-07-31 21:28:03 +00002961- Issue #3479: On platforms where sizeof(int) is smaller than sizeof(long)
2962 (64bit Unix, for example), unichr() would truncate its argument and return
2963 u'\x00' for unichr(2**32). Now it properly raises an OverflowError.
2964
Neal Norwitze7d8be82008-07-31 17:17:14 +00002965- Apply security patches from Apple.
2966
Amaury Forgeot d'Arc246daed2008-07-31 00:42:16 +00002967- Issue #2542: Now that issubclass() may call arbitrary code, ensure that
2968 PyErr_ExceptionMatches returns 0 when an exception occurs there.
2969
Antoine Pitrou92f82162008-07-25 22:22:08 +00002970- Issue #1819: function calls with several named parameters are now on
2971 average 35% faster (as measured by pybench).
2972
Amaury Forgeot d'Arce4921fe2008-07-21 22:00:38 +00002973- Issue #2378: An unexpected UnboundLocalError or NameError could appear when
2974 the python debugger steps into a class statement: the free variables (local
2975 variables defined in an outer scope) would be deleted from the outer scope.
2976
Gregory P. Smith0470bab2008-07-22 04:46:32 +00002977- Issue #2620: Overflow checking when allocating or reallocating memory
2978 was not always being done properly in some python types and extension
2979 modules. PyMem_MALLOC, PyMem_REALLOC, PyMem_NEW and PyMem_RESIZE have
2980 all been updated to perform better checks and places in the code that
2981 would previously leak memory on the error path when such an allocation
2982 failed have been fixed.
2983
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00002984Library
2985-------
2986
Hirokazu Yamamoto838c79f2008-08-20 13:14:07 +00002987- Issue #3612: Added some missing basic types in ctypes.wintypes.
2988
Benjamin Petersone977ad42008-08-20 01:42:01 +00002989- The methods ``is_in_tuple()``, ``is_vararg()``, and ``is_keywordarg()`` of
2990 symtable.Symbol have been deprecated for removal in 3.0 and the next release.
2991
Amaury Forgeot d'Arc351ffb82008-08-18 19:23:47 +00002992- Issue #2234: distutils failed for some versions of the cygwin compiler. The
2993 version reported by these tools does not necessarily follow the python
2994 version numbering scheme, so the module is less strict when parsing it.
2995
Nick Coghlanf70385a2008-08-18 12:42:46 +00002996- Issue #2235: Added Py3k warnings for types which will become unhashable
2997 under the stricter __hash__ inheritance rules in 3.0. Several types
2998 which did not meet the rules for hash invariants and were already
2999 unhashable in 3.0 have now been explicitly flagged as unhashable in
3000 2.6 as well (collections.Mapping, collections.Set, unittest.TestSuite,
3001 xml.dom.minidom.NamedNodeMap, numbers.Number, UserList.UserList)
3002
Brett Cannon88f801d2008-08-18 00:46:22 +00003003- Update __all__ for cookielib, csv, os, urllib2, and weakref to include things
3004 imported into the module but exposed as part of the module's API.
3005
Brett Cannon7b96f072008-08-18 00:41:11 +00003006- Remove an unneeded import of abc.ABCMeta from 'inspect'.
3007
Brett Cannon46225e72008-08-18 00:36:52 +00003008- Remove unneeded imports of 'sys' and 'warnings' from 'io'.
3009
Brett Cannon25c9d6a2008-08-17 22:10:11 +00003010- Remove unneeded imports of 'warnings' from shelve, filecmp, and dummy_thread.
3011
Hirokazu Yamamoto41a81eb2008-08-17 13:10:46 +00003012- Issue #3575: Incremental decoder's decode function now takes bytearray
3013 by using 's*' instead of 't#'.
3014
Mark Dickinson3e4caeb2009-02-21 20:27:01 +00003015- Issue #2222: Fixed reference leak when occurred os.rename()
Hirokazu Yamamoto7f30a682008-08-17 09:46:56 +00003016 fails unicode conversion on 2nd parameter. (windows only)
3017
Facundo Batista94f243a2008-08-17 03:38:39 +00003018- Issue 2464. urllib2 now supports a malformation in the URL received
3019 in a redirect.
3020
Brett Cannonabe423e2008-08-16 21:47:07 +00003021- Silence the DeprecationWarning raised when importing mimetools in
Brett Cannon721b1452008-08-16 22:00:27 +00003022 BaseHTTPServer, cgi (and rfc822), httplib.
Brett Cannonabe423e2008-08-16 21:47:07 +00003023
Facundo Batistaeb90b782008-08-16 14:44:07 +00003024- Issue #2776: fixed small issue when handling an URL with double slash
3025 after a 302 response in the case of not going through a proxy.
3026
Antoine Pitroub90a8be2008-08-15 21:03:21 +00003027- Issue #2676: in the email package, content-type parsing was hanging on
3028 pathological input because of quadratic or exponential behaviour of a
3029 regular expression.
3030
Antoine Pitrou11ec65d2008-08-14 21:04:30 +00003031- Issue #3476: binary buffered reading through the new "io" library is now
3032 thread-safe.
3033
Brett Cannonbf3157b2008-08-14 05:00:03 +00003034- Silence the DeprecationWarning of rfc822 when it is imported by mimetools
3035 since mimetools itself is deprecated. Because modules are cached, all
3036 subsequent imports of rfc822 will not raise a visible DeprecationWarning.
3037
Antoine Pitrou9fcd4b32008-08-11 17:21:36 +00003038- Issue #3134: shutil referenced undefined WindowsError symbol.
3039
Robert Schuppenies14646332008-08-10 11:01:53 +00003040- Issue #1342811: Fix leak in Tkinter.Menu.delete. Commands associated to
3041 menu entries were not deleted.
3042
Brett Cannon83e81842008-08-09 23:30:55 +00003043- Copied the implementation of reduce() to _functools.reduce() to have a
3044 version that did not raise a DeprecationWarning under -3.
3045
Antoine Pitrou76b8bee2008-08-09 17:27:23 +00003046- Issue #3205: When iterating over a BZ2File fails allocating memory, raise
3047 a MemoryError rather than silently stop the iteration.
3048
Guido van Rossum59ce9012008-08-09 14:55:34 +00003049- Issue #3487: sre "bytecode" validator. Passing invalid "re-bytecode"
3050 to _sre.compile() will now be rejected. This should not affect anybody
3051 since the re.compile() function never generates invalid re-bytecode.
3052
Skip Montanaroa032bf42008-08-08 22:52:51 +00003053- Issue #3436: Make csv.DictReader's fieldnames attribute a property so that
3054 upon first access it can be automatically initialized from the csv file if
3055 it wasn't initialized during instantiation.
3056
Brett Cannon3aa2a492008-08-06 22:28:09 +00003057- Issue #2338: Create imp.reload() to help with transitioning to Python 3.0 as
3058 the reload() built-in has been removed.
3059
Brett Cannon7e30b672008-08-04 21:52:25 +00003060- Changed code in the following modules/packages to remove warnings raised
Brett Cannonc1b76e42008-08-09 23:06:16 +00003061 while running under the ``-3`` flag: aifc, asynchat, asyncore, bdb, bsddb,
Brett Cannon047e4a92008-08-17 04:16:04 +00003062 ConfigParser, cookielib, csv, difflib, distutils, DocXMLRPCServer, email,
3063 filecmp, fileinput, inspect, logging, modulefinder, pdb, pickle, profile,
3064 pstats, pydoc, re, rlcompleter, SimpleXMLRPCServer, shelve, socket,
3065 subprocess, sqlite3, tarfile, Tkinter, test.test_support, textwrap,
3066 threading, tokenize, traceback, urlparse, wsgiref, xml, xmlrpclib.
Brett Cannon7e30b672008-08-04 21:52:25 +00003067
Lars Gustäbel727bd0b2008-08-02 11:26:39 +00003068- Issue #3039: Fix tarfile.TarFileCompat.writestr() which always
3069 raised an AttributeError.
3070
Benjamin Peterson01a24322008-07-28 23:35:27 +00003071- Issue #2523: Fix quadratic behaviour when read()ing a binary file without
Antoine Pitroude781a42008-08-09 12:43:23 +00003072 asking for a specific length. This problem only affected files opened
3073 using the new "io" module, not the built-in open() function.
Benjamin Peterson01a24322008-07-28 23:35:27 +00003074
Mark Dickinsonfe84cce2008-07-27 06:39:07 +00003075- Issue #3449: Update decimal module to use most recent specification
3076 (v. 1.68) and tests (v. 2.58) from IBM.
3077
Skip Montanarof9ac43f2008-07-27 00:50:41 +00003078- Issue 3437: Bug fix in robotparser parsing of Allow: lines.

3086
3087- Issue #3303: Fix a crash in locale.strcoll() when calling it with
3088 invalid arguments.
3089
3090- Issue #3302: Fix several crashes when calling locale's gettext functions
3091 with None arguments.
3092
3093- Issue #3389: Allow resolving dotted names for handlers in logging
3094 configuration files.
3095
3096- Deprecate the sunaudio module for removal in Python 3.0.
3097
Antoine Pitrou5fdfa3e2008-07-25 19:42:26 +00003098- Issue #3394: zipfile.writestr sets external attributes when passed a
3099 file name rather than a ZipInfo instance, so files are extracted with
3100 mode 0600 rather than 000 under Unix.
3101
Gregory P. Smitha36f8fe2008-08-04 00:13:29 +00003102- Issue #1857: subprocess.Popen.poll gained an additional _deadstate keyword
3103 argument in python 2.5, this broke code that subclassed Popen to include its
3104 own poll method. Fixed my moving _deadstate to an _internal_poll method.

3112-------------
3113
Nick Coghlan6e8fef02008-08-18 13:14:22 +00003114- Issue #2235: the C API function PyObject_HashNotImplemented and its
3115 interaction with the tp_hash slot (added in 2.6b2) are now documented
3116
Nick Coghlan2a0c2b12008-08-04 12:47:17 +00003117- Issue #643841: The language reference now provides more detailed
3118 coverage of the lookup process for special methods. The disclaimers
3119 regarding lack of coverage of new-style classes have also been
3120 removed, since the coverage is now fairly reasonable.

Raymond Hettingere3ae6552008-06-20 04:18:15 +00003123What's New in Python 2.6 beta 2?
3124================================
3125
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00003126*Release date: 17-Jul-2008*
3127
Raymond Hettingere3ae6552008-06-20 04:18:15 +00003128Core and Builtins
3129-----------------
3130
Georg Brandl3e483f62008-07-16 22:57:41 +00003131- Issue #3156: Fix inconsistent behavior of the bytearray type: all
3132 its methods now allow for items objects that can be converted to
3133 an integer using operator.index().
3134
Mark Dickinson64b7e502008-07-16 09:40:03 +00003135- Issue #3360: Fix incorrect parsing of '020000000000.0', which
3136 produced a ValueError instead of giving the correct float.
3137
Eric Smitha5fa5a22008-07-16 00:11:49 +00003138- Issue #3083: Add alternate (#) formatting for bin, oct, hex output
3139 for str.format(). This adds the prefix 0b, 0o, or 0x, respectively.
3140
Mark Dickinson7103aa42008-07-15 19:08:33 +00003141- Issue #3008: the float type has a new instance method 'float.hex'
3142 and a new class method 'float.fromhex' to convert floating-point
3143 numbers to and from hexadecimal strings, respectively.
3144
Nick Coghlan6d6bd442008-07-15 15:40:22 +00003145- Issue #2235: __hash__ is once again inherited by default. To allow
3146 collections.Hashable to remain meaningful in the presence of the
3147 default hash implementation (object.__hash__), it is now possible
3148 to explicit block inheritance of hash by setting __hash__=None at
3149 the Python level, or tp_hash=PyObject_HashNotImplemented at the C
3150 level.
3151
Nick Coghlanb028f502008-07-13 14:52:36 +00003152- Issue #3221: Issue a RuntimeWarning instead of raising SystemError if
3153 the parent module cannot be found while performing an absolute import.
3154 This means that an incorrectly defined __package__ attribute will
3155 now only prevent relative imports in that module rather than causing
3156 all imports from that module to fail.
3157
Nick Coghlan14ff9942008-07-08 14:21:42 +00003158- Issue #2517: Allow unicode messages in Exceptions again by correctly
3159 bypassing the instance dictionary when looking up __unicode__ on
3160 new-style classes.
3161
Amaury Forgeot d'Arcbdd941f2008-07-01 20:38:04 +00003162- Issue #3242: Fix a crash inside the print statement, if sys.stdout is
3163 set to a custom object whose write() method happens to install
3164 another file in sys.stdout.
3165
Amaury Forgeot d'Arc1f40c8a2008-06-30 22:42:40 +00003166- Issue #3088: Corrected a race condition in classes derived from
3167 threading.local: the first member set by a thread could be saved in
3168 another thread's dictionary.
3169
Mark Dickinson1ec2fcd2008-06-20 14:53:43 +00003170- Issue #3004: Minor change to slice.indices(): the start and stop
3171 arguments are now treated identically, making the behaviour easier
3172 to describe and understand. For example, slice(None, -10,
3173 1).indices(9) now returns (0, 0, 1) instead of (0, -1, 1), and
3174 slice(None, 10, -1).indices(10) returns (9, 9, -1) instead of (9,
3175 10, -1).
3176
Georg Brandl278fc502008-07-19 12:46:12 +00003177- Issue #3219: Calling a function with repeated keyword arguments,
3178 f(a=2, a=23), would not cause a syntax error. This was a regression
3179 from 2.4 caused by the switch to the new compiler.
Benjamin Peterson175e4d92008-07-01 19:34:52 +00003180
Georg Brandl278fc502008-07-19 12:46:12 +00003181- Issue #2862: Make int and float freelist management consistent with
3182 other freelists. Changes their CompactFreeList apis into
3183 ClearFreeList apis and calls them via gc.collect().
Gregory P. Smith2fe77062008-07-06 03:35:58 +00003184

3187
Thomas Heller57adf222008-08-14 19:10:48 +00003188- Issue #3554: ctypes.string_at and ctypes.wstring_at did call Python
3189 api functions without holding the GIL, which could lead to a fatal
3190 error when they failed.
3191
Martin v. Löwisaabf4042008-08-02 07:20:25 +00003192- Issue #799428: Fix Tkinter.Misc._nametowidget to unwrap Tcl command objects.

Jesse Noller13e9d582008-07-16 14:32:36 +00003200- Issue #3125: Remove copy_reg in multiprocessing and replace it with
3201 ForkingPickler.register() to resolve conflict with ctypes.
3202
Vinay Sajip51e65192008-07-18 09:01:10 +00003203- Issue #3090: Fixed ARCHFLAGS parsing on OS/X

3206 a valid dlerror() message.
3207
Thomas Heller2bad6572008-07-15 17:19:50 +00003208- Issue #3258: Fixed a crash when a ctypes POINTER type to an
3209 incomplete structure was created.
3210
Brett Cannon3d0b9f02008-07-13 01:15:07 +00003211- Issue #3339: dummy_thread.acquire() should not return None.
3212
Raymond Hettingerb01713e2008-07-10 14:34:57 +00003213- Issue #3285: Fractions from_float() and from_decimal() accept Integral arguments.
3214
Andrew M. Kuchlingcc3f2b12008-07-10 14:43:31 +00003215- Issue #3301: Bisect module behaved badly when lo was negative.

3628 mode or even as a 4-way universal binary (that is, PPC, i386,
Georg Brandl5cc774e2008-06-11 20:28:06 +00003629 PPC64 and x86_64 support in one binary).
Ronald Oussoren5640ce22008-06-05 12:58:24 +00003630
3631 This is controlled by the configure argument ``--with-universal-archs``:
3632
3633 - ``--with-universal-archs=all``: install 4-way universal
3634
3635 - ``--with-universal-archs=32-bit``: install 2-way universal, 32-bit (the default)
3636
3637 - ``--with-universal-archs=64-bit``: install 2-way universal, 64-bit
3638
3639 This option should be used in combination with ``--enable-universalsdk=``.
3640
3641 NOTE: 64-bit and 4-way builds are only suppported on Mac OS X 10.5 (or later).

3678 two handlers that derive the same default base class.
Amaury Forgeot d'Arc96865852008-04-22 21:14:41 +00003679
Christian Heimese74c8f22008-04-19 02:23:57 +00003680- Added kill, terminate and send_signal(sig) to subprocess.Popen.
3681
Georg Brandl3ee81df2008-05-17 18:14:43 +00003682- Added phase(z) -> phi, polar(z) -> r, phi and rect(r, phi) -> z to
3683 the cmath module.
Christian Heimes6f341092008-04-18 23:13:07 +00003684

Georg Brandl3ee81df2008-05-17 18:14:43 +00003691- Issue #1631171: Re-implement the 'warnings' module in C (the
3692 original Python code has been kept as backup). This will allow for
3693 using the 'warning's machinery in such places as the parser where
3694 use of pure Python code is not possible. Both the ``showarning()``
3695 and ``formatwarning()`` gain an optional 'line' argument which is
3696 not called by default for backwards-compatibility reasons. Setting
3697 ``warnings.showwarning()`` to an implementation that lacks support
3698 for the ``line`` argument will raise a DeprecationWarning.

3722
Gregory P. Smithd59fefb2008-04-22 08:11:33 +00003723- The getpass module has been improved on Unix. It now uses /dev/tty
3724 by default and uses stderr instead of stdout. A GetPassWarning is
3725 issued when input echo cannot be controlled.
Gregory P. Smith41e30182008-04-21 21:31:08 +00003726

Georg Brandl3ee81df2008-05-17 18:14:43 +00003740- Issue #2513: distutils on Windows is now capable of cross-compiling
Mark Hammond495cf992008-04-07 01:53:39 +00003741 extension modules between 32 and 64 bit platforms. See the distutls

Georg Brandl3ee81df2008-05-17 18:14:43 +00003761- Issue #2550: The approach used by client/server code for obtaining
3762 ports to listen on in network-oriented tests has been refined in an
3763 effort to facilitate running multiple instances of the entire
3764 regression test suite in parallel without issue.
3765 test_support.bind_port() has been fixed such that it will always
3766 return a unique port -- which wasn't always the case with the
3767 previous implementation, especially if socket options had been set
3768 that affected address reuse (i.e. SO_REUSEADDR, SO_REUSEPORT). The
3769 new implementation of bind_port() will actually raise an exception
3770 if it is passed an AF_INET/SOCK_STREAM socket with either the
3771 SO_REUSEADDR or SO_REUSEPORT socket option set. Furthermore, if
3772 available, bind_port() will set the SO_EXCLUSIVEADDRUSE option on
3773 the socket it's been passed. This currently only applies to
3774 Windows. This option prevents any other sockets from binding to the
3775 host/port we've bound to, thus removing the possibility of the
3776 'non-deterministic' behaviour, as Microsoft puts it, that occurs
3777 when a second SOCK_STREAM socket binds and accepts to a host/port
3778 that's already been bound by another socket. The optional preferred
3779 port parameter to bind_port() has been removed. Under no
3780 circumstances should tests be hard coding ports!
3781
3782 test_support.find_unused_port() has also been introduced, which will
3783 pass a temporary socket object to bind_port() in order to obtain an
3784 unused port. The temporary socket object is then closed and
3785 deleted, and the port is returned. This method should only be used
3786 for obtaining an unused port in order to pass to an external program
3787 (i.e. the -accept [port] argument to openssl's s_server mode) or as
3788 a parameter to a server-oriented class that doesn't give you direct
3789 access to the underlying socket used.
3790
3791 Finally, test_support.HOST has been introduced, which should be used
3792 for the host argument of any relevant socket calls (i.e. bind and
3793 connect).

4067Core and builtins
4068-----------------
4069
Fred Drakea8ee94b2008-03-01 02:45:07 +00004070- Issue #2051: pyc and pyo files are no longer created with permission
Barry Warsaw52973612008-03-01 02:23:38 +00004071 644. The mode is now inherited from the py file.
Christian Heimes40346852008-02-23 17:52:07 +00004072
Georg Brandlad61bc82008-02-23 15:11:18 +00004073- Issue #2067: file.__exit__() now calls subclasses' close() method.
4074
4075- Patch #1759: Backport of PEP 3129 class decorators.
Christian Heimes5224d282008-02-23 15:01:05 +00004076
Vinay Sajipb7edfc42008-04-02 21:10:23 +00004077- Issue #1881: An internal parser limit has been increased. Also see
Facundo Batistafc2d0102008-02-23 12:01:13 +00004078 issue 215555 for a discussion.
4079
Eric Smitha73fbe72008-02-23 03:09:44 +00004080- Added the future_builtins module, which contains hex() and oct().
4081 These are the PEP 3127 version of these functions, designed to be
4082 compatible with the hex() and oct() builtins from Python 3.0. They
4083 differ slightly in their output formats from the existing, unchanged
4084 Python 2.6 builtins. The expected usage of the future_builtins
4085 module is:
4086 from future_builtins import hex, oct
4087
Eric Smith7ef40bf2008-02-20 23:34:22 +00004088- Issue #1600: Modifed PyOS_ascii_formatd to use at most 2 digit
4089 exponents for exponents with absolute value < 100. Follows C99
4090 standard. This is a change on Windows, which would use 3 digits.
4091 Also, added 'n' to the formats that PyOS_ascii_formatd understands,
4092 so that any alterations it does to the resulting string will be
4093 available in stringlib/formatter.h (for float.__format__).
4094
Eric Smith5a3c1352008-02-19 13:21:56 +00004095- Implemented PEP 3101, Advanced String Formatting. This adds a new
4096 builtin format(); a format() method for str and unicode; a
4097 __format__() method to object, str, unicode, int, long, float, and
4098 datetime; the class string.Formatter; and the C API
4099 PyObject_Format().
4100
Georg Brandl3ee81df2008-05-17 18:14:43 +00004101- Fixed several potential crashes, all caused by specially crafted
4102 __del__ methods exploiting objects in temporarily inconsistent
4103 state.
Amaury Forgeot d'Arc632fad32008-02-16 20:55:24 +00004104
Vinay Sajipb7edfc42008-04-02 21:10:23 +00004105- Issue #2115: Important speedup in setting __slot__ attributes. Also
Georg Brandl3ee81df2008-05-17 18:14:43 +00004106 prevent a possible crash: an Abstract Base Class would try to access
4107 a slot on a registered virtual subclass.
Amaury Forgeot d'Arc60d6c7f2008-02-15 21:22:45 +00004108
Georg Brandl3ee81df2008-05-17 18:14:43 +00004109- Fixed repr() and str() of complex numbers with infinity or nan as
4110 real or imaginary part.
Christian Heimes2f0da532008-02-15 06:57:08 +00004111
Georg Brandl3ee81df2008-05-17 18:14:43 +00004112- Clear all free lists during a gc.collect() of the highest generation
4113 in order to allow pymalloc to free more arenas. Python may give back
4114 memory to the OS earlier.
Christian Heimes3b718a72008-02-14 12:47:33 +00004115
Georg Brandl3ee81df2008-05-17 18:14:43 +00004116- Issue #2045: Fix an infinite recursion triggered when printing a
4117 subclass of collections.defaultdict, if its default_factory is set
4118 to a bound method.
Amaury Forgeot d'Arcb01aa432008-02-08 00:56:02 +00004119
Christian Heimesf75dbef2008-02-08 00:11:31 +00004120- Fixed a minor memory leak in dictobject.c. The content of the free
4121 list was not freed on interpreter shutdown.
4122
Georg Brandl21e99f42010-03-07 15:23:59 +00004123- Limit free list of method and built-in function objects to 256
Georg Brandl3ee81df2008-05-17 18:14:43 +00004124 entries each.
Christian Heimes6075a822008-02-06 12:44:34 +00004125
Georg Brandl3ee81df2008-05-17 18:14:43 +00004126- Patch #1953: Added ``sys._compact_freelists()`` and the C API
4127 functions ``PyInt_CompactFreeList`` and ``PyFloat_CompactFreeList``
Christian Heimes422051a2008-02-04 18:00:12 +00004128 to compact the internal free lists of pre-allocted ints and floats.
4129
Georg Brandl3ee81df2008-05-17 18:14:43 +00004130- Issue #1983: Fixed return type of fork(), fork1() and forkpty()
4131 calls. Python expected the return type int but the fork familie
4132 returns pi_t.
Christian Heimes951cc0f2008-01-31 23:08:23 +00004133
Georg Brandl3ee81df2008-05-17 18:14:43 +00004134- Issue #1678380: Fix a bug that identifies 0j and -0j when they
4135 appear in the same code unit.
Mark Dickinson105be772008-01-31 22:17:37 +00004136
Georg Brandl3ee81df2008-05-17 18:14:43 +00004137- Issue #2025: Add tuple.count() and tuple.index() methods to comply
4138 with the collections.Sequence API.
Raymond Hettinger5b07ebc2008-02-07 00:54:20 +00004139
Georg Brandl3ee81df2008-05-17 18:14:43 +00004140- Patch #1970 by Antoine Pitrou: Speedup unicode whitespace and
4141 linebreak detection
Christian Heimes4d4f2702008-01-30 11:32:37 +00004142
Georg Brandl3ee81df2008-05-17 18:14:43 +00004143- Added ``PyType_ClearCache()`` and ``sys._clear_type_cache`` to clear
4144 the internal lookup cache for ref leak tests.
Christian Heimes908caac2008-01-27 23:34:59 +00004145
Georg Brandl3ee81df2008-05-17 18:14:43 +00004146- Patch #1473257: generator objects gain a gi_code attribute. This is
4147 the same object as the func_code attribute of the function that
4148 produced the generator.
Georg Brandl0cdf9a32008-01-26 14:14:20 +00004149
Georg Brandl3ee81df2008-05-17 18:14:43 +00004150- Issue #1920: "while 0" statements were completely removed by the
4151 compiler, even in the presence of an "else" clause, which is
4152 supposed to be run when the condition is false. Now the compiler
4153 correctly emits bytecode for the "else" suite.
Amaury Forgeot d'Arc31eaafe2008-01-24 22:59:25 +00004154
Guido van Rossumeead05f2008-01-24 18:21:02 +00004155- A few crashers fixed: weakref_in_del.py (issue #1377858);
4156 loosing_dict_ref.py (issue #1303614, test67.py);
4157 borrowed_ref_[34].py (not in tracker).
4158
Vinay Sajipd7cf32e2008-01-24 12:43:33 +00004159- Issue #1069410: The "can't load dll" message box on Windows is
Christian Heimesb2302ba2008-01-23 17:15:06 +00004160 suppressed while an extension is loaded by calling SetErrorMode in
4161 dynload_win.c. The error is still reported properly.
4162
Georg Brandl3ee81df2008-05-17 18:14:43 +00004163- Issue #1915: Python compiles with --enable-unicode=no again. However
Christian Heimes082c9b02008-01-23 14:20:50 +00004164 several extension methods and modules do not work without unicode
4165 support.
4166
Georg Brandl26543b12008-01-21 18:36:51 +00004167- Issue #1882: when compiling code from a string, encoding cookies in the
4168 second line of code were not always recognized correctly.
4169
Georg Brandl14404b62008-01-19 19:27:05 +00004170- Issue #1679: "0x" was taken as a valid integer literal.
4171
Georg Brandl6caad7d2008-01-26 14:19:22 +00004172- Issue #1865: ``bytes`` as an alias for ``str`` and b"" as an alias "" were
Christian Heimes288e89a2008-01-18 18:24:07 +00004173 added.
4174
Christian Heimesc94e2b52008-01-14 04:13:37 +00004175- sys.float_info / PyFloat_GetInfo: The floating point information
4176 object was converted from a dict to a specialized structseq object.
4177
Georg Brandl3ee81df2008-05-17 18:14:43 +00004178- Patch #1816: Added sys.flags structseq. It exposes the status of
4179 most command line arguments and PYTHON* environment variables.
Christian Heimesf31b69f2008-01-14 03:42:48 +00004180
Georg Brandl3ee81df2008-05-17 18:14:43 +00004181- Objects/structseq.c: Implemented new structseq representation. The
4182 patch makes structseqs (e.g. the return value of os.stat) more
4183 readable.
Christian Heimes9c201962008-01-14 03:33:52 +00004184
Georg Brandl3ee81df2008-05-17 18:14:43 +00004185- Patch #1700288: added a type attribute cache that caches method
4186 accesses, resulting in speedups in heavily object-oriented code.
Amaury Forgeot d'Arce4c270c2008-01-14 00:29:41 +00004187
Neal Norwitz3fc15b82008-01-10 05:42:58 +00004188- Bug #1776: __import__() no longer accepts filenames on any platform.
4189 The first parameter to __import__() must be a valid module name.
Christian Heimes3403f152008-01-09 19:56:33 +00004190
Georg Brandlaed6c662008-01-07 17:25:53 +00004191- Patch #1668: renamed THREADDEBUG envvar to PYTHONTHREADDEBUG.
4192
Georg Brandl3ee81df2008-05-17 18:14:43 +00004193- Patch #602345: Add -B command line option, PYTHONDONTWRITEBYTECODE
4194 envvar and sys.dont_write_bytecode attribute. All these can be set
4195 to forbid Python to attempt to write compiled bytecode files.
Georg Brandl2da0fce2008-01-07 17:09:35 +00004196
Georg Brandl3ee81df2008-05-17 18:14:43 +00004197- Improve some exception messages when Windows fails to load an
4198 extension module. Now we get for example '%1 is not a valid Win32
4199 application' instead of 'error code 193'.
Amaury Forgeot d'Arce0b76952008-01-04 02:04:15 +00004200
Georg Brandl3ee81df2008-05-17 18:14:43 +00004201- Bug #1481296: Fixed long(float('nan')) != 0L.

Georg Brandl3ee81df2008-05-17 18:14:43 +00004203- Issue #1640: Added math.isinf(x), math.isnan(x) and math.copysign(x,
4204 y) functions.
Christian Heimese2ca4242008-01-03 20:23:15 +00004205
Christian Heimes0a8143f2007-12-18 23:22:54 +00004206- Issue #1635: Platform independent creation and representation of NaN
Georg Brandl3ee81df2008-05-17 18:14:43 +00004207 and INF. float("nan"), float("inf") and float("-inf") now work on
4208 every platform with IEEE 754 semantics.
Christian Heimes0a8143f2007-12-18 23:22:54 +00004209
Georg Brandl3ee81df2008-05-17 18:14:43 +00004210- Compiler now generates simpler and faster code for dictionary
4211 literals. The oparg for BUILD_MAP now indicates an estimated
4212 dictionary size. There is a new opcode, STORE_MAP, for adding
4213 entries to the dictionary.
Raymond Hettingerfd7ed402007-12-18 21:24:09 +00004214
Georg Brandl3ee81df2008-05-17 18:14:43 +00004215- Issue #1638: %zd configure test fails on Linux.

4221 is not found.
Skip Montanaro26015492007-12-08 15:33:24 +00004222
Andrew M. Kuchling395fe442007-12-05 13:27:20 +00004223- Issue #1553: An erroneous __length_hint__ can make list() raise a
Christian Heimes7cc1c6f2007-12-05 12:52:34 +00004224 SystemError.
4225
Nick Coghlanef01d822007-12-03 12:55:17 +00004226- PEP 366: Allow explicit relative imports when executing modules
4227 inside packages with the -m switch via a new module level
4228 __package__ attribute.
4229
Georg Brandl3ee81df2008-05-17 18:14:43 +00004230- Issue #1402: Fix a crash on exit, when another thread is still
4231 running, and if the deallocation of its frames somehow calls the
4232 PyGILState_Ensure() / PyGILState_Release() functions.
Amaury Forgeot d'Arcbe49a902007-11-30 20:37:22 +00004233

Georg Brandl3ee81df2008-05-17 18:14:43 +00004242- Patch #1739468: Directories and zipfiles containing a __main__.py
4243 file can now be directly executed by passing their name to the
4244 interpreter. The directory/zipfile is automatically inserted as the
4245 first entry in sys.path.
Nick Coghlan327a39b2007-11-18 11:56:28 +00004246
Georg Brandl3ee81df2008-05-17 18:14:43 +00004247- Issue #1265: Fix a problem with sys.settrace, if the tracing
4248 function uses a generator expression when at the same time the
4249 executed code is closing a paused generator.
Amaury Forgeot d'Arc0d75f092007-11-13 21:54:28 +00004250
Raymond Hettinger1760c8a2007-11-08 02:52:43 +00004251- sets and frozensets now have an isdisjoint() method.
4252
Raymond Hettinger3f8caa32007-10-24 01:28:33 +00004253- optimize the performance of builtin.sum().
4254
Neal Norwitz44f326e2007-10-05 05:29:17 +00004255- Fix warnings found by the new version of the Coverity checker.
4256
Georg Brandl21e99f42010-03-07 15:23:59 +00004257- The enumerate() built-in function is no longer bounded to sequences
Georg Brandl3ee81df2008-05-17 18:14:43 +00004258 smaller than LONG_MAX. Formerly, it raised an OverflowError. Now,
4259 automatically shifts from ints to longs.
Raymond Hettinger8f669372007-10-03 21:18:11 +00004260
Georg Brandl3ee81df2008-05-17 18:14:43 +00004261- Issue #1686386: Tuple's tp_repr did not take into account the
4262 possibility of having a self-referential tuple, which is possible
4263 from C code. Nor did object's tp_str consider that a type's tp_str
4264 could do something that could lead to an inifinite recursion.
4265 Py_ReprEnter() and Py_EnterRecursiveCall(), respectively, fixed the
4266 issues.
Brett Cannon0b14f242007-09-30 19:45:10 +00004267
Georg Brandl3ee81df2008-05-17 18:14:43 +00004268- Issue #1164: It was possible to trigger deadlock when using the
4269 'print' statement to write to a file since the GIL was not released
4270 as needed. Now PyObject_Print() does the right thing along with

Georg Brandl3ee81df2008-05-17 18:14:43 +00004274- Issue #1147: Exceptions were directly allowing string exceptions in
4275 their throw() method even though string exceptions no longer
4276 allowed.

Georg Brandl3ee81df2008-05-17 18:14:43 +00004278- Issue #1096: Prevent a segfault from getting the repr of a very
4279 deeply nested list by using the recursion counter.
Brett Cannona0c05512007-09-10 21:38:27 +00004280
Brett Cannon1e534b52007-09-07 04:18:30 +00004281- Issue #1202533: Fix infinite recursion calls triggered by calls to
Georg Brandl3ee81df2008-05-17 18:14:43 +00004282 PyObject_Call() never calling back out to Python code to trigger
4283 recursion depth updates/checks. Required the creation of a static
4284 RuntimeError instance in case normalizing an exception put the
4285 recursion check value past its limit. Fixes crashers
4286 infinite_rec_(1|2|4|5).py.
Brett Cannon1e534b52007-09-07 04:18:30 +00004287

Neal Norwitz0ac60192007-05-27 04:08:54 +00004301- Add new attribute names for function objects. All the func_* become
Georg Brandl3ee81df2008-05-17 18:14:43 +00004302 __*__ attributes. (Some already existed, e.g., __doc__ and
4303 __name__.)
Neal Norwitz0ac60192007-05-27 04:08:54 +00004304
Neal Norwitz8b2bfbc2007-05-23 06:35:32 +00004305- Add -3 option to the interpreter to warn about features that are

4309 calls.
4310
Collin Winter62903052007-05-18 23:11:24 +00004311- except clauses may now be spelled either "except E, target:" or
Georg Brandl3ee81df2008-05-17 18:14:43 +00004312 "except E as target:". This is to provide forwards compatibility
4313 with Python 3.0.
Collin Winter62903052007-05-18 23:11:24 +00004314
Brett Cannon229cee22007-05-05 01:34:02 +00004315- Deprecate BaseException.message as per PEP 352.
4316
Georg Brandl3ee81df2008-05-17 18:14:43 +00004317- Issue #1303614: don't expose object's __dict__ when the dict is
Georg Brandl21e99f42010-03-07 15:23:59 +00004318 inherited from a built-in base.

Vinay Sajip8549ce32007-05-06 17:53:37 +00004320- When __slots__ are set to a unicode string, make it work the same as
Neal Norwitzcbd9ee62007-04-14 05:25:50 +00004321 setting a plain string, ie don't expand to single letter identifiers.
4322
Raymond Hettinger13936692007-04-11 18:40:58 +00004323- Request #1191699: Slices can now be pickled.
4324
Raymond Hettinger4db5fe92007-04-12 04:10:00 +00004325- Request #1193128: str.translate() now allows a None argument for
4326 translations that only remove characters without re-mapping the
4327 remaining characters.
4328
Georg Brandl5cb76c12007-03-21 09:00:39 +00004329- Patch #1682205: a TypeError while unpacking an iterable is no longer
4330 masked by a generic one with the message "unpack non-sequence".
4331

4333
Guido van Rossum143b5642007-03-23 04:58:42 +00004334- Bug #1683368: The object.__init__() and object.__new__() methods are
4335 now stricter in rejecting excess arguments. The only time when
4336 either allows excess arguments is when it is not overridden and the
4337 other one is. For backwards compatibility, when both are
4338 overridden, it is a deprecation warning (for now; maybe a Py3k
Guido van Rossum234b1ff2007-03-23 19:39:01 +00004339 warning later). Also, type.__init__() insists on the same signature
4340 as supported by type.__new__().
Guido van Rossum143b5642007-03-23 04:58:42 +00004341
Georg Brandl3ee81df2008-05-17 18:14:43 +00004342- Patch #1675423: PyComplex_AsCComplex() now tries to convert an
4343 object to complex using its __complex__() method before falling back
4344 to the __float__() method. Therefore, the functions in the cmath
4345 module now can operate on objects that define a __complex__()
4346 method.
Georg Brandl2b869942007-03-17 16:08:45 +00004347
Georg Brandl3ee81df2008-05-17 18:14:43 +00004348- Patch #1623563: allow __class__ assignment for classes with
4349 __slots__. The old and the new class are still required to have the
4350 same slot names.

4357 its type.
Žiga Seilnacht20f43d32007-03-15 11:44:55 +00004358
Georg Brandl3ee81df2008-05-17 18:14:43 +00004359- Patch #1680015: Don't modify __slots__ tuple if it contains an

4363
Georg Brandl7b9c5552007-03-12 14:30:05 +00004364- Bug #1678647: write a newline after printing an exception in any
4365 case, even when converting the value to a string failed.
4366
Georg Brandl871f1bc2007-03-12 13:17:36 +00004367- The dir() function has been extended to call the __dir__() method on
Georg Brandl3ee81df2008-05-17 18:14:43 +00004368 its argument, if it exists. If not, it will work like before. This
4369 allows customizing the output of dir() in the presence of a
4370 __getattr__().
Georg Brandl871f1bc2007-03-12 13:17:36 +00004371
Collin Winter276887b2007-03-12 16:11:39 +00004372- Patch #922167: Python no longer segfaults when faced with infinitely
4373 self-recursive reload() calls (as reported by bug #742342).
4374

4379 parthensized forms. This means complex(repr(x)) now works instead of
4380 raising a ValueError.
Collin Wintere38051d2007-03-09 20:33:07 +00004381
Georg Brandlaa2321b2007-03-07 00:40:28 +00004382- Patch #703779: unset __file__ in __main__ after running a file. This
Georg Brandl3ee81df2008-05-17 18:14:43 +00004383 makes the filenames the warning module prints much more sensible
4384 when a PYTHONSTARTUP file is used.
Georg Brandlaa2321b2007-03-07 00:40:28 +00004385
Georg Brandl49aafc92007-03-07 00:34:46 +00004386- Variant of patch #697613: don't exit the interpreter on a SystemExit
4387 exception if the -i command line option or PYTHONINSPECT environment
Georg Brandl3ee81df2008-05-17 18:14:43 +00004388 variable is given, but break into the interactive interpreter just
4389 like on other exceptions or normal program exit.

Georg Brandl0fca97a2007-03-05 22:28:08 +00004397- Patch #1674228: when assigning a slice (old-style), check for the
4398 sq_ass_slice instead of the sq_slice slot.
4399
Georg Brandl3ee81df2008-05-17 18:14:43 +00004400- When printing an unraisable error, don't print exceptions. before
4401 the name. This duplicates the behavior whening normally printing
4402 exceptions.

5011 Python would crash instead of raising an error.
5012
Thomas Hellerc2f77252007-03-09 19:21:28 +00005013- Bug #1646630: ctypes.string_at(buf, 0) and ctypes.wstring_at(buf, 0)
5014 returned string up to the first NUL character.

5025
Georg Brandl3ee81df2008-05-17 18:14:43 +00005026- unittest now verifies more of its assumptions. In particular,
5027 TestCase and TestSuite subclasses (not instances) are no longer
5028 accepted in TestSuite.addTest(). This should cause no
5029 incompatibility since it never made sense with ordinary subclasses
5030 -- the failure just occurred later, with a more cumbersome
5031 exception.

5315 Fenner.
Gregory P. Smith2b3ba582008-01-17 08:03:17 +00005316
Georg Brandl3ee81df2008-05-17 18:14:43 +00005317- Issue #1339: The smtplib.SMTP class has been refactored a bit such
Gregory P. Smithbde4ae42008-01-17 08:35:49 +00005318 that the SMTP.starttls() caller no longer needs to call ehlo()
5319 beforehand. SMTP.starttls() now raises an exception of the server
Georg Brandl3ee81df2008-05-17 18:14:43 +00005320 does not claim to support starttls. Adds the
5321 SMTP.ehlo_or_helo_if_needed() method. Patch contributed by Bill

5402 complex, tuple, list, dict, set, and frozenset. Formerly, it would
5403 silently miscode subclasses of those types. Now, it raises a

Georg Brandl3ee81df2008-05-17 18:14:43 +00005420 time so that opening a database previously created with the DB_DUP
5421 or DB_DUPSORT flag set will keep the proper behavior on subsequent
5422 opens. Specifically: dictionary assignment to a DB object will
5423 replace all values for a given key when the database allows
5424 duplicate values. DB users should use DB.put(k, v) when they want
5425 to store duplicates; not DB[k] = v.
Gregory P. Smithec10a4a2007-11-05 02:32:26 +00005426

5432 characters with ASCII value less than 32. Also, it correctly quotes
5433 dots only if they occur on a single line, as opposed to the previous
5434 behavior of quoting dots if they are the second character of any
5435 line.

5758-----
5759
Georg Brandl3ee81df2008-05-17 18:14:43 +00005760- Unified naming convention for free lists and their limits. All free
5761 lists in Object/ are named ``free_list``, the counter ``numfree``
5762 and the upper limit is a macro ``PyName_MAXFREELIST`` inside an
5763 #ifndef block.
Christian Heimes5b970ad2008-02-06 13:33:44 +00005764
Georg Brandl3ee81df2008-05-17 18:14:43 +00005765- ``PySet_Add()`` can now modify a newly created frozenset. Similarly
5766 to ``PyTuple_SetItem``, it can be used to populate a brand new
5767 frozenset; but it does not steal a reference to the added item.
Amaury Forgeot d'Arccab3d982008-02-03 22:51:43 +00005768
Vinay Sajipb7edfc42008-04-02 21:10:23 +00005769- Added ``PySet_Check()`` and ``PyFrozenSet_Check()`` to the set API.

Georg Brandl3ee81df2008-05-17 18:14:43 +00005771- Backport of PyUnicode_FromString(), _FromStringAndSize(), _Format
5772 and _FormatV from Python 3.0. Made PyLong_AsSsize_t and
5773 PyLong_FromSsize_t public functions.
Georg Brandl6caad7d2008-01-26 14:19:22 +00005774
5775- Patch #1720595: add T_BOOL to the range of structmember types.
5776
5777- Issue #1534: Added ``PyFloat_GetMax()``, ``PyFloat_GetMin()`` and
5778 ``PyFloat_GetInfo()`` to the float API.
5779
Georg Brandl3ee81df2008-05-17 18:14:43 +00005780- Issue #1521: On 64bit platforms, using PyArgs_ParseTuple with the t#
5781 of w# format code incorrectly truncated the length to an int, even
5782 when PY_SSIZE_T_CLEAN is set. The str.decode method used to return
5783 incorrect results with huge strings.
Georg Brandl6caad7d2008-01-26 14:19:22 +00005784
Georg Brandl3ee81df2008-05-17 18:14:43 +00005785- Issue #1629: Renamed Py_Size, Py_Type and Py_Refcnt to Py_SIZE,
5786 Py_TYPE and Py_REFCNT.
Georg Brandl6caad7d2008-01-26 14:19:22 +00005787
Georg Brandl3ee81df2008-05-17 18:14:43 +00005788- PEP 3123: Provide forward compatibility with Python 3.0, while
5789 keeping backwards compatibility. Add Py_Refcnt, Py_Type, Py_Size,
5790 and PyVarObject_HEAD_INIT.
Georg Brandl6caad7d2008-01-26 14:19:22 +00005791
Georg Brandl3ee81df2008-05-17 18:14:43 +00005792- Py_ssize_t fields work in structmember when HAVE_LONG_LONG is not
5793 defined.
Georg Brandl6caad7d2008-01-26 14:19:22 +00005794
5795- Patch #1733960: Allow T_LONGLONG to accept ints.
5796
5797- T_PYSSIZET can now be used in PyMemberDef lists for Py_ssize_t members.
5798

5802
5803- Fix some leftovers from the conversion from int to Py_ssize_t
5804 (relevant to strings and sequences of more than 2**31 items).
5805
5806- Make _PyGILState_NoteThreadState() static, it was not used anywhere
5807 outside of pystate.c and should not be necessary.
5808
Georg Brandl3ee81df2008-05-17 18:14:43 +00005809- ``PyImport_Import`` and ``PyImport_ImportModule`` now always do
5810 absolute imports. In earlier versions they might have used relative
5811 imports under some conditions.
Christian Heimes000a0742008-01-03 22:16:32 +00005812
Georg Brandl3ee81df2008-05-17 18:14:43 +00005813- Added case insensitive comparison methods ``PyOS_stricmp(char*,
5814 char*)`` and ``PyOS_strnicmp(char*, char*, Py_ssize_t)``.
Christian Heimes000a0742008-01-03 22:16:32 +00005815
Georg Brandl3ee81df2008-05-17 18:14:43 +00005816- Bug #1542693: remove semi-colon at end of PyImport_ImportModuleEx
5817 macro so it can be used as an expression.

5822
Georg Brandl3ee81df2008-05-17 18:14:43 +00005823- Patch #1706: Drop support for Win9x, WinME and NT4. Python now
5824 requires Windows 2000 or greater. The _WINVER and NTDDI_VERSION
5825 macros are set to Win2k for x86/32bit builds and WinXP for AMD64
5826 builds.
Christian Heimes95d64472008-02-09 19:55:22 +00005827
Georg Brandl3ee81df2008-05-17 18:14:43 +00005828- Conditionalize definition of _CRT_SECURE_NO_DEPRECATE and

Georg Brandl3ee81df2008-05-17 18:14:43 +00005841- Removed the macfs module. It had been deprecated since Python 2.5.
5842 This lead to the deprecation of macostools.touched() as it relied
5843 solely on macfs and was a no-op under OS X.
