114 designed to follow. This improves compatibility with patch tools.
115
R. David Murray27ef9372010-04-12 14:26:06 +0000116- Issue #7472: Fixed typo in email.encoders module; messages using ISO-2022

150Core and Builtins
151-----------------
152
Philip Jenveyaebbaeb2010-04-06 23:24:45 +0000153- Issue #7301: Add environment variable $PYTHONWARNINGS.
154

156 changed.
157
Mark Dickinson82791672010-04-06 16:47:55 +0000158- Issue #8259: 1L << (2**31) no longer produces an 'outrageous shift error'
159 on 64-bit machines. The shift count for either left or right shift is
160 permitted to be up to sys.maxsize.
161
Benjamin Peterson4ceeeb02010-04-03 22:48:51 +0000162- Ensure that tokenization of identifiers is not affected by locale.

169 is called with a non-empty format string. This is an effort to
170 future-proof user code. If a derived class does not currently
171 implement __format__ but later adds its own __format__, it would
172 most likely break user code that had supplied a format string. This
173 will be changed to a DeprecationWaring in Python 3.3 and it will be
174 an error in Python 3.4.
175
Antoine Pitroua57df2c2010-03-31 21:32:15 +0000176- Issue #8268: Old-style classes (not just instances) now support weak

Georg Brandlba83f822010-03-14 09:50:54 +0000190 (SIGINT). If an error occurs while importing the site module, the error is
191 printed and Python exits. Initialize the GIL before importing the site
Victor Stinner66644262010-03-10 22:30:19 +0000192 module.
193
Collin Winter001a3952010-03-18 21:54:01 +0000194- Code objects now support weak references.

202 using the new attributes `ssl.OPENSSL_VERSION`, `ssl.OPENSSL_VERSION_INFO`
203 and `ssl.OPENSSL_VERSION_NUMBER`.
204
Benjamin Peterson76a23c12010-04-04 23:23:22 +0000205- Issue #8310: Allow dis to examine new style classes.
206
Mark Dickinson8a950712010-04-03 15:47:46 +0000207- Issue #8257: The Decimal construct now accepts a float instance
208 directly, converting that float to a Decimal of equal value:

214
Raymond Hettingera551f312010-04-04 18:34:45 +0000215- the functools module now has a total_ordering() class decorator
Georg Brandl4fabac52010-04-14 08:53:38 +0000216 to simplify the specification of rich comparisons.
Raymond Hettingera551f312010-04-04 18:34:45 +0000217
Raymond Hettingerbb006cf2010-04-04 21:45:01 +0000218- The functools module also adds cmp_to_key() as a tool to transition
Raymond Hettingera551f312010-04-04 18:34:45 +0000219 old-style comparison functions to new-style key-functions.
220
Mark Dickinson7c63eee2010-04-02 22:27:36 +0000221- Issue #8294: The Fraction constructor now accepts Decimal and float
222 instances directly.
223
Mark Dickinsone096e822010-04-02 10:17:07 +0000224- Issue #7279: Comparisons involving a Decimal signaling NaN now
225 signal InvalidOperation instead of returning False. (Comparisons
Mark Dickinsonf3eeca12010-04-02 10:35:12 +0000226 involving a quiet NaN are unchanged.) Also, Decimal quiet NaNs
227 are now hashable; Decimal signaling NaNs remain unhashable.
Mark Dickinsone096e822010-04-02 10:17:07 +0000228
Mark Dickinson99d80962010-04-02 08:53:22 +0000229- Issue #2531: Comparison operations between floats and Decimal

235 argument `-` which tells it to read files to compile from stdin. Each line
236 is read on demand and the named file is compiled immediately. (Original
237 patch by Piotr Ożarowski).
238
239- Issue #3135: Add inspect.getcallargs, which binds arguments to a function
240 like a normal call.
Benjamin Peterson7e213252010-03-30 17:58:13 +0000241
Florent Xicluna58b65662010-03-30 16:29:03 +0000242- Backwards incompatible change: Unicode codepoints line tabulation (0x0B) and
243 form feed (0x0C) are now considered linebreaks, as specified in Unicode
244 Standard Annex #14. See issue #7643.
Florent Xicluna22b24382010-03-30 08:24:06 +0000245 http://www.unicode.org/reports/tr14/
246
Mark Dickinson9588d992010-03-27 11:14:37 +0000247- Comparisons using one of <, <=, >, >= between a complex instance and
248 a Fractions instance now raise TypeError instead of returning
249 True/False. This makes Fraction <=> complex comparisons consistent with
250 int <=> complex, float <=> complex, and complex <=> complex comparisons.
251
Michael Foorde6410c52010-03-29 20:04:23 +0000252- Addition of ``WeakSet`` to the ``weakref`` module.

263 now silenced.
264
Florent Xicluna9e7a4c92010-03-22 16:07:38 +0000265- Issue #7703: ctypes supports both buffer() and memoryview(). The former is
266 deprecated.
267
R. David Murrayc9d1a782010-03-22 15:55:09 +0000268- Issue #7860: platform.uname now reports the correct 'machine' type
269 when Python is running in WOW64 mode on 64 bit Windows.
270

282 Also, enable the SSL_MODE_AUTO_RETRY flag on SSL sockets, so that blocking
283 reads and writes are always retried by OpenSSL itself.
Antoine Pitrou448da712010-03-21 19:33:38 +0000284

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

Georg Brandlba83f822010-03-14 09:50:54 +0000354- Issue #1530559: When passing a non-integer argument to struct.pack with *any*
355 integer format code (one of 'bBhHiIlLqQ'), struct.pack attempts to use the
356 argument's __int__ method to convert to an integer before packing. It also
357 produces a DeprecationWarning in this case. (In Python 2.6, the behaviour
358 was inconsistent: __int__ was used for some integer codes but not for others,
359 and the set of integer codes for which it was used differed between native
360 packing and standard packing.)

585 and read operations on write-only file objects. On Windows, the system C
Georg Brandlba83f822010-03-14 09:50:54 +0000586 library would return a bogus result; on Solaris, it was possible to crash the

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

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

Vinay Sajip28c382f2010-02-04 18:48:53 +0000655- logging: Implemented PEP 391.
656
Antoine Pitrouf3fa0742010-01-31 22:26:04 +0000657- Issue #6939: Fix file I/O objects in the `io` module to keep the original
Georg Brandlba83f822010-03-14 09:50:54 +0000658 file position when calling `truncate()`. It would previously change the file
659 position to the given argument, which goes against the tradition of
Antoine Pitrouf3fa0742010-01-31 22:26:04 +0000660 ftruncate() and other truncation APIs. Patch by Pascal Chambon.
661
Benjamin Petersone06f7112010-01-28 02:15:02 +0000662- UserDict is now a new-style class.
663
Georg Brandlba83f822010-03-14 09:50:54 +0000664- Issue #7610: Reworked implementation of the internal ``zipfile.ZipExtFile``
665 class used to represent files stored inside an archive. The new
666 implementation is significantly faster and can be wrapped in a
667 ``io.BufferedReader`` object for more speedups. It also solves an issue
668 where interleaved calls to ``read()`` and ``readline()`` give wrong results.
669 Patch by Nir Aides.

677 when the release file is empty.
Benjamin Petersona43f34c2010-01-25 03:31:13 +0000678
Georg Brandlba83f822010-03-14 09:50:54 +0000679- Issue #7748: Since unicode values are supported for some metadata options in
680 Distutils, the DistributionMetadata get_* methods will now return an utf-8
681 encoded string for them. This ensures that the upload and register commands
682 send the correct values to PyPI without any error.

756Core and Builtins
757-----------------
758
Georg Brandlba83f822010-03-14 09:50:54 +0000759- The ``__complex__()`` method is now looked up on the class of instances to
760 make it consistent with other special methods.
Benjamin Petersonecdae192010-01-04 00:43:01 +0000761
Antoine Pitrou5b7139a2010-01-02 21:12:58 +0000762- Issue #7462: Implement the stringlib fast search algorithm for the `rfind`,
763 `rindex`, `rsplit` and `rpartition` methods. Patch by Florent Xicluna.
764
Mark Dickinson1b34d252010-01-01 17:27:30 +0000765- Issue #5080: A number of functions and methods previously produced a
Georg Brandlba83f822010-03-14 09:50:54 +0000766 DeprecationWarning when passed a float argument where an integer was expected.
767 These functions and methods now raise TypeError instead. The majority of the
768 effects of this change are in the extension modules, but some core functions
769 and methods are affected: notably the 'chr', 'range' and 'xrange' builtins,
770 and many unicode/str methods.

782
Georg Brandlba83f822010-03-14 09:50:54 +0000783- Issue #1811: Improve accuracy and cross-platform consistency for true division
784 of integers: the result of a/b is now correctly rounded for ints a and b (at
785 least on IEEE 754 platforms), and in particular does not depend on the
786 internal representation of a long.
Mark Dickinson46572832009-12-27 14:55:57 +0000787
Georg Brandlba83f822010-03-14 09:50:54 +0000788- Issue #6108: ``unicode(exception)`` and ``str(exception)`` should return the
789 same message when only ``__str__()`` (and not ``__unicode__()``) is overridden
790 in the subclass.

794
Georg Brandlba83f822010-03-14 09:50:54 +0000795 These executables now work properly with the arch(1) command: ``arch -ppc
796 python`` will start a universal binary version of python in PPC mode (unlike
797 previous releases).
Ronald Oussoren92919a62009-12-24 13:30:58 +0000798

Georg Brandlba83f822010-03-14 09:50:54 +0000953- Issue #7117: ``repr(x)`` for a float x returns a result based on the shortest
954 decimal string that's guaranteed to round back to x under correct rounding
955 (with round-half-to-even rounding mode). Previously it gave a string based on
956 rounding x to 17 decimal digits. repr(x) for a complex number behaves
957 similarly. On platforms where the correctly-rounded strtod and dtoa code is
958 not supported (see below), repr is unchanged.
Mark Dickinsonb678de82009-11-19 18:41:49 +0000959
Georg Brandlba83f822010-03-14 09:50:54 +0000960- Issue #7117: On almost all platforms: float-to-string and string-to-float
961 conversions within Python are now correctly rounded. Places these conversions
962 occur include: str for floats and complex numbers; the float and complex
963 constructors; old-style and new-style numeric formatting; serialization and
964 deserialization of floats and complex numbers using marshal, pickle and json;
965 parsing of float and imaginary literals in Python code; Decimal-to-float
966 conversion.
Mark Dickinsonb678de82009-11-19 18:41:49 +0000967
Georg Brandlba83f822010-03-14 09:50:54 +0000968 The conversions use a Python-adapted version of David Gay's well-known dtoa.c,
969 providing correctly-rounded strtod and dtoa C functions. This code is
970 supported on Windows, and on Unix-like platforms using gcc, icc or suncc as
971 the C compiler. There may be a small number of platforms on which correct
972 operation of this code cannot be guaranteed, so the code is not used: notably,
973 this applies to platforms where the C double format is not IEEE 754 binary64,
974 and to platforms on x86 hardware where the x87 FPU is set to 64-bit precision
975 and Python's configure script is unable to determine how to change the FPU
976 precision. On these platforms conversions use the platform strtod and dtoa,
977 as before.

Georg Brandlba83f822010-03-14 09:50:54 +0000979- Issue #7117: Backport round implementation from Python 3.x. ``round()`` now
980 uses the correctly-rounded string <-> float conversions described above (when
981 available), and so produces correctly rounded results that will display nicely
982 under the float repr. There are two related small changes: (1) round now
983 accepts any class with an ``__index__()`` method for its second argument (but
984 no longer accepts floats for the second argument), and (2) an excessively
985 large second integer argument (e.g., ``round(1.234, 10**100)``) no longer
986 raises an exception.

Georg Brandlba83f822010-03-14 09:50:54 +00001133- Issue #5920: For ``float.__format__()``, change the behavior with the empty
1134 presentation type (that is, not one of 'e', 'f', 'g', or 'n') to be like 'g'
1135 but with at least one decimal point and with a default precision
1136 of 12. Previously, the behavior the same but with a default precision of 6.
1137 This more closely matches ``str()``, and reduces surprises when adding
1138 alignment flags to the empty presentation type. This also affects the new
1139 complex.__format__ in the same way.

Georg Brandlba83f822010-03-14 09:50:54 +00001279- Issue #1180193: When importing a module from a .pyc (or .pyo) file with an
1280 existing .py counterpart, override the co_filename attributes of all code
1281 objects if the original filename is obsolete (which can happen if the file has

1336
Georg Brandlba83f822010-03-14 09:50:54 +00001337- Issue #4233: Changed semantic of ``_fileio.FileIO``'s ``close()`` method on
1338 file objects with closefd=False. The file descriptor is still kept open but
1339 the file object behaves like a closed file. The ``FileIO`` object also got a
1340 new readonly attribute ``closefd``.

Benjamin Peterson399b1fe2008-10-25 02:53:28 +00001360- Using ``nonlocal`` as a variable name will now raise a Py3k SyntaxWarning

Georg Brandlba83f822010-03-14 09:50:54 +00001363- On windows, ``os.chdir()`` given unicode was not working if
1364 GetCurrentDirectoryW returned a path longer than MAX_PATH. (But It's doubtful
1365 this code path is really executed because I cannot move to such directory on
1366 win2k)

Georg Brandlba83f822010-03-14 09:50:54 +00001368- Issue #4069: When ``set.remove(element)`` is used with a set element, the
1369 element is temporarily replaced with an equivalent frozenset. But the
1370 eventual KeyError would always report the empty ``frozenset()`` as the missing
1371 key. Now it correctly refers to the initial element.

Walter Dörwalded960ac2009-05-03 22:36:33 +00001391- Issue #5108: Handle %s like %S and %R in PyUnicode_FromFormatV(): Call
1392 PyUnicode_DecodeUTF8() once, remember the result and output it in a second
1393 step. This avoids problems with counting UTF-8 bytes that ignores the effect
1394 of using the replace error handler in PyUnicode_DecodeUTF8().
1395
Walter Dörwald726ba8e2009-05-06 14:32:35 +00001396- Issue #3739: The unicode-internal encoder now reports the number of characters

1398
Georg Brandlba83f822010-03-14 09:50:54 +00001399- Issue #2422: When compiled with the ``--with-valgrind`` option, the pymalloc

1401 gives improved memory leak detection when running under Valgrind, while taking
1402 advantage of pymalloc at other times.

2633 __all__ attribute, rather than using a hardcoded and incomplete list.
2634
R. David Murray14dcd432009-10-14 13:58:07 +00002635- Issue #7058: Added save/restore for things like sys.argv and cwd to
2636 runtest_inner in regrtest, with warnings if the called test modifies them,
2637 and a new section in the summary report at the end.

2642 off the trailing 0 in the version number.
2643
Guilherme Polo7f146ab2009-06-21 17:22:50 +00002644- Issue #5450: Moved tests involving loading tk from Lib/test/test_tcl to
2645 Lib/lib-tk/test/test_tkinter/test_loadtk. With this, these tests demonstrate
Georg Brandlba83f822010-03-14 09:50:54 +00002646 the same behaviour as test_ttkguionly (and now also test_tk) which is to skip
2647 the tests if DISPLAY is defined but can't be used.

Antoine Pitrou4698d992009-05-31 14:20:14 +00002649- Issue #6152: New option '-j'/'--multiprocess' for regrtest allows running
2650 regression tests in parallel, shortening the total runtime.
2651
Georg Brandlba83f822010-03-14 09:50:54 +00002652- Issue #5354: New test support function import_fresh_module() makes it easy to
2653 import both normal and optimised versions of modules. test_heapq and
2654 test_warnings have been adjusted to use it, tests for other modules with both
2655 C and Python implementations in the stdlib can be adjusted to use it over
2656 time.

Georg Brandlba83f822010-03-14 09:50:54 +00002664- regrtest no longer treats ImportError as equivalent to SkipTest. Imports that
2665 should cause a test to be skipped are now done using import_module from test
2666 support, which does the conversion.

Martin v. Löwis9fa5a282008-09-11 06:53:30 +00002767- Issue #3642: Suppress warning in obmalloc when size_t is larger than uint.
2768
Amaury Forgeot d'Arc05e34492008-09-10 22:04:45 +00002769- Issue #3743: In a few places, PY_FORMAT_SIZE_T was incorrectly used with
2770 PyString_FromFormat or PyErr_Format to display size_t values. The macro
2771 PY_FORMAT_SIZE_T is designed to select the correct format for the OS
2772 ``printf`` function, whereas PyString_FromFormat has an independent
2773 implementation and uses "%zd" on all platforms for size_t values.
2774 This makes a difference on win64, where ``printf`` needs "%Id" to display
2775 64bit values.

Benjamin Peterson97179b02008-09-09 20:55:01 +00002777- Issue #3634: _weakref.ref(Exception).__init__() gave invalid return value on

2781 object; previously an int would be returned for small values. the __long__
2782 method is allowed to return either an int or a long, but the behaviour of
2783 float objects should not change to respect backward compatibility.

Amaury Forgeot d'Arc3571fbf2008-09-01 19:52:00 +00002785- Issue #3751: str.rpartition would perform a left-partition when called with

Vinay Sajip35e3b032008-09-01 14:33:59 +00002791 PyArg_ParseTuple and friends, which occurred when the argument for "s*"
Antoine Pitroud4ae97b2008-08-29 18:39:48 +00002792 was correctly parsed but parsing of subsequent arguments failed.
2793
Vinay Sajip35e3b032008-09-01 14:33:59 +00002794- Issue #2534: speed up isinstance() and issubclass() by 50-70%, so as to
Antoine Pitrou0668c622008-08-26 22:42:08 +00002795 match Python 2.5 speed despite the __instancecheck__ / __subclasscheck__
2796 mechanism. In the process, fix a bug where isinstance() and issubclass(),
2797 when given a tuple of classes as second argument, were looking up
2798 __instancecheck__ / __subclasscheck__ on the tuple rather than on each
2799 type object.
2800
Neal Norwitz18aa3882008-08-24 05:04:52 +00002801- Fix crashes on memory allocation failure found with failmalloc.

Martin v. Löwisab0b29b2008-09-13 08:11:57 +00002927- Issue #3833: Use a different upgrade code for Win64 installers.
2928
Martin v. Löwis3f5fda82008-09-08 13:50:10 +00002929- Issue #2271: Set SecureCustomProperties so that installation will properly
2930 use the TARGETDIR even for unprivileged users.
2931
Martin v. Löwis67543a92008-09-08 12:02:45 +00002932- Allow passing the MSI file name to merge.py.
2933
Vinay Sajip844f7412008-09-09 13:42:08 +00002934- Issue #3758: Rename the 'check' target to 'patchcheck' so as to not clash
Amaury Forgeot d'Arcfeb8cad2008-09-06 20:53:51 +00002935 with GNU build target guidelines.

Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00002938What's New in Python 2.6 beta 3?
2939================================
2940
Barry Warsaw07a4a382008-08-21 01:15:08 +00002941*Release date: 20-Aug-2008*
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00002942
2943Core and Builtins
2944-----------------
2945
Guido van Rossumf8402962008-08-20 15:01:50 +00002946- Issue #1878: Remove Py_TPFLAGS_HAVE_VERSION_TAG from
2947 Py_TPFLAGS_DEFAULT when not building the core. This means 3rd party
2948 extensions do not automatically benefit from the class attribute
2949 cache; they will have to explicitly add Py_TPFLAGS_HAVE_VERSION_TAG
2950 to their tp_flags field if they care. This is a backwards
2951 compatibility feature; in 3.0, all types will use the cache by
2952 default.
2953
Benjamin Petersonf647dc12008-08-20 01:27:30 +00002954- Keyword arguments can now follow starred arguments. (``f(a, *args,
2955 keyword=23)`` is now valid syntax.)
2956
Thomas Heller0ad5ae02008-08-19 19:25:04 +00002957- ctypes function pointers that are COM methods have a boolean True
2958 value again.
2959
Martin v. Löwisf91d46a2008-08-12 14:49:50 +00002960- Issue #3139: Make buffer-interface thread-safe wrt. PyArg_ParseTuple,
2961 by denying s# to parse objects that have a releasebuffer procedure,
2962 and introducing s*.
2963
Georg Brandl1e13ea92008-08-11 09:07:59 +00002964- Issue #3537: Fix an assertion failure when an empty but presized dict
2965 object was stored in the freelist.
2966
Mark Dickinsonb6467572008-08-04 21:30:09 +00002967- Issue #1481296: Make long(float('nan')) and int(float('nan')) raise
2968 ValueError consistently across platforms.
2969
Amaury Forgeot d'Arc39fd6722008-07-31 21:28:03 +00002970- Issue #3479: On platforms where sizeof(int) is smaller than sizeof(long)
2971 (64bit Unix, for example), unichr() would truncate its argument and return
2972 u'\x00' for unichr(2**32). Now it properly raises an OverflowError.
2973
Neal Norwitze7d8be82008-07-31 17:17:14 +00002974- Apply security patches from Apple.
2975
Amaury Forgeot d'Arc246daed2008-07-31 00:42:16 +00002976- Issue #2542: Now that issubclass() may call arbitrary code, ensure that
2977 PyErr_ExceptionMatches returns 0 when an exception occurs there.
2978
Antoine Pitrou92f82162008-07-25 22:22:08 +00002979- Issue #1819: function calls with several named parameters are now on
2980 average 35% faster (as measured by pybench).
2981
Amaury Forgeot d'Arce4921fe2008-07-21 22:00:38 +00002982- Issue #2378: An unexpected UnboundLocalError or NameError could appear when
2983 the python debugger steps into a class statement: the free variables (local
2984 variables defined in an outer scope) would be deleted from the outer scope.
2985
Gregory P. Smith0470bab2008-07-22 04:46:32 +00002986- Issue #2620: Overflow checking when allocating or reallocating memory
2987 was not always being done properly in some python types and extension
2988 modules. PyMem_MALLOC, PyMem_REALLOC, PyMem_NEW and PyMem_RESIZE have
2989 all been updated to perform better checks and places in the code that
2990 would previously leak memory on the error path when such an allocation
2991 failed have been fixed.
2992
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00002993Library
2994-------
2995
Hirokazu Yamamoto838c79f2008-08-20 13:14:07 +00002996- Issue #3612: Added some missing basic types in ctypes.wintypes.
2997
Benjamin Petersone977ad42008-08-20 01:42:01 +00002998- The methods ``is_in_tuple()``, ``is_vararg()``, and ``is_keywordarg()`` of
2999 symtable.Symbol have been deprecated for removal in 3.0 and the next release.
3000
Amaury Forgeot d'Arc351ffb82008-08-18 19:23:47 +00003001- Issue #2234: distutils failed for some versions of the cygwin compiler. The
3002 version reported by these tools does not necessarily follow the python
3003 version numbering scheme, so the module is less strict when parsing it.
3004
Nick Coghlanf70385a2008-08-18 12:42:46 +00003005- Issue #2235: Added Py3k warnings for types which will become unhashable
3006 under the stricter __hash__ inheritance rules in 3.0. Several types
3007 which did not meet the rules for hash invariants and were already
3008 unhashable in 3.0 have now been explicitly flagged as unhashable in
3009 2.6 as well (collections.Mapping, collections.Set, unittest.TestSuite,
3010 xml.dom.minidom.NamedNodeMap, numbers.Number, UserList.UserList)
3011
Brett Cannon88f801d2008-08-18 00:46:22 +00003012- Update __all__ for cookielib, csv, os, urllib2, and weakref to include things
3013 imported into the module but exposed as part of the module's API.
3014
Brett Cannon7b96f072008-08-18 00:41:11 +00003015- Remove an unneeded import of abc.ABCMeta from 'inspect'.
3016
Brett Cannon46225e72008-08-18 00:36:52 +00003017- Remove unneeded imports of 'sys' and 'warnings' from 'io'.
3018
Brett Cannon25c9d6a2008-08-17 22:10:11 +00003019- Remove unneeded imports of 'warnings' from shelve, filecmp, and dummy_thread.
3020
Hirokazu Yamamoto41a81eb2008-08-17 13:10:46 +00003021- Issue #3575: Incremental decoder's decode function now takes bytearray
3022 by using 's*' instead of 't#'.
3023
Mark Dickinson3e4caeb2009-02-21 20:27:01 +00003024- Issue #2222: Fixed reference leak when occurred os.rename()
Hirokazu Yamamoto7f30a682008-08-17 09:46:56 +00003025 fails unicode conversion on 2nd parameter. (windows only)
3026
Facundo Batista94f243a2008-08-17 03:38:39 +00003027- Issue 2464. urllib2 now supports a malformation in the URL received
3028 in a redirect.
3029
Brett Cannonabe423e2008-08-16 21:47:07 +00003030- Silence the DeprecationWarning raised when importing mimetools in
Brett Cannon721b1452008-08-16 22:00:27 +00003031 BaseHTTPServer, cgi (and rfc822), httplib.
Brett Cannonabe423e2008-08-16 21:47:07 +00003032
Facundo Batistaeb90b782008-08-16 14:44:07 +00003033- Issue #2776: fixed small issue when handling an URL with double slash
3034 after a 302 response in the case of not going through a proxy.
3035
Antoine Pitroub90a8be2008-08-15 21:03:21 +00003036- Issue #2676: in the email package, content-type parsing was hanging on
3037 pathological input because of quadratic or exponential behaviour of a
3038 regular expression.
3039
Antoine Pitrou11ec65d2008-08-14 21:04:30 +00003040- Issue #3476: binary buffered reading through the new "io" library is now
3041 thread-safe.
3042
Brett Cannonbf3157b2008-08-14 05:00:03 +00003043- Silence the DeprecationWarning of rfc822 when it is imported by mimetools
3044 since mimetools itself is deprecated. Because modules are cached, all
3045 subsequent imports of rfc822 will not raise a visible DeprecationWarning.
3046
Antoine Pitrou9fcd4b32008-08-11 17:21:36 +00003047- Issue #3134: shutil referenced undefined WindowsError symbol.
3048
Robert Schuppenies14646332008-08-10 11:01:53 +00003049- Issue #1342811: Fix leak in Tkinter.Menu.delete. Commands associated to
3050 menu entries were not deleted.
3051
Brett Cannon83e81842008-08-09 23:30:55 +00003052- Copied the implementation of reduce() to _functools.reduce() to have a
3053 version that did not raise a DeprecationWarning under -3.
3054
Antoine Pitrou76b8bee2008-08-09 17:27:23 +00003055- Issue #3205: When iterating over a BZ2File fails allocating memory, raise
3056 a MemoryError rather than silently stop the iteration.
3057
Guido van Rossum59ce9012008-08-09 14:55:34 +00003058- Issue #3487: sre "bytecode" validator. Passing invalid "re-bytecode"
3059 to _sre.compile() will now be rejected. This should not affect anybody
3060 since the re.compile() function never generates invalid re-bytecode.
3061
Skip Montanaroa032bf42008-08-08 22:52:51 +00003062- Issue #3436: Make csv.DictReader's fieldnames attribute a property so that
3063 upon first access it can be automatically initialized from the csv file if
3064 it wasn't initialized during instantiation.
3065
Brett Cannon3aa2a492008-08-06 22:28:09 +00003066- Issue #2338: Create imp.reload() to help with transitioning to Python 3.0 as
3067 the reload() built-in has been removed.
3068
Brett Cannon7e30b672008-08-04 21:52:25 +00003069- Changed code in the following modules/packages to remove warnings raised
Brett Cannonc1b76e42008-08-09 23:06:16 +00003070 while running under the ``-3`` flag: aifc, asynchat, asyncore, bdb, bsddb,
Brett Cannon047e4a92008-08-17 04:16:04 +00003071 ConfigParser, cookielib, csv, difflib, distutils, DocXMLRPCServer, email,
3072 filecmp, fileinput, inspect, logging, modulefinder, pdb, pickle, profile,
3073 pstats, pydoc, re, rlcompleter, SimpleXMLRPCServer, shelve, socket,
3074 subprocess, sqlite3, tarfile, Tkinter, test.test_support, textwrap,
3075 threading, tokenize, traceback, urlparse, wsgiref, xml, xmlrpclib.
Brett Cannon7e30b672008-08-04 21:52:25 +00003076
Lars Gustäbel727bd0b2008-08-02 11:26:39 +00003077- Issue #3039: Fix tarfile.TarFileCompat.writestr() which always
3078 raised an AttributeError.
3079
Benjamin Peterson01a24322008-07-28 23:35:27 +00003080- Issue #2523: Fix quadratic behaviour when read()ing a binary file without
Antoine Pitroude781a42008-08-09 12:43:23 +00003081 asking for a specific length. This problem only affected files opened
3082 using the new "io" module, not the built-in open() function.
Benjamin Peterson01a24322008-07-28 23:35:27 +00003083
Mark Dickinsonfe84cce2008-07-27 06:39:07 +00003084- Issue #3449: Update decimal module to use most recent specification
3085 (v. 1.68) and tests (v. 2.58) from IBM.
3086
Skip Montanarof9ac43f2008-07-27 00:50:41 +00003087- Issue 3437: Bug fix in robotparser parsing of Allow: lines.
3088

3095
3096- Issue #3303: Fix a crash in locale.strcoll() when calling it with
3097 invalid arguments.
3098
3099- Issue #3302: Fix several crashes when calling locale's gettext functions
3100 with None arguments.
3101
3102- Issue #3389: Allow resolving dotted names for handlers in logging
3103 configuration files.
3104
3105- Deprecate the sunaudio module for removal in Python 3.0.
3106
Antoine Pitrou5fdfa3e2008-07-25 19:42:26 +00003107- Issue #3394: zipfile.writestr sets external attributes when passed a
3108 file name rather than a ZipInfo instance, so files are extracted with
3109 mode 0600 rather than 000 under Unix.
3110
Gregory P. Smitha36f8fe2008-08-04 00:13:29 +00003111- Issue #1857: subprocess.Popen.poll gained an additional _deadstate keyword
3112 argument in python 2.5, this broke code that subclassed Popen to include its
3113 own poll method. Fixed my moving _deadstate to an _internal_poll method.

3121-------------
3122
Nick Coghlan6e8fef02008-08-18 13:14:22 +00003123- Issue #2235: the C API function PyObject_HashNotImplemented and its
3124 interaction with the tp_hash slot (added in 2.6b2) are now documented
3125
Nick Coghlan2a0c2b12008-08-04 12:47:17 +00003126- Issue #643841: The language reference now provides more detailed
3127 coverage of the lookup process for special methods. The disclaimers
3128 regarding lack of coverage of new-style classes have also been
3129 removed, since the coverage is now fairly reasonable.

Raymond Hettingere3ae6552008-06-20 04:18:15 +00003132What's New in Python 2.6 beta 2?
3133================================
3134
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00003135*Release date: 17-Jul-2008*

Raymond Hettingere3ae6552008-06-20 04:18:15 +00003137Core and Builtins
3138-----------------
3139
Georg Brandl3e483f62008-07-16 22:57:41 +00003140- Issue #3156: Fix inconsistent behavior of the bytearray type: all
3141 its methods now allow for items objects that can be converted to
3142 an integer using operator.index().
3143
Mark Dickinson64b7e502008-07-16 09:40:03 +00003144- Issue #3360: Fix incorrect parsing of '020000000000.0', which
3145 produced a ValueError instead of giving the correct float.
3146
Eric Smitha5fa5a22008-07-16 00:11:49 +00003147- Issue #3083: Add alternate (#) formatting for bin, oct, hex output
3148 for str.format(). This adds the prefix 0b, 0o, or 0x, respectively.
3149
Mark Dickinson7103aa42008-07-15 19:08:33 +00003150- Issue #3008: the float type has a new instance method 'float.hex'
3151 and a new class method 'float.fromhex' to convert floating-point
3152 numbers to and from hexadecimal strings, respectively.
3153
Nick Coghlan6d6bd442008-07-15 15:40:22 +00003154- Issue #2235: __hash__ is once again inherited by default. To allow
3155 collections.Hashable to remain meaningful in the presence of the
3156 default hash implementation (object.__hash__), it is now possible
3157 to explicit block inheritance of hash by setting __hash__=None at
3158 the Python level, or tp_hash=PyObject_HashNotImplemented at the C
3159 level.
3160
Nick Coghlanb028f502008-07-13 14:52:36 +00003161- Issue #3221: Issue a RuntimeWarning instead of raising SystemError if
3162 the parent module cannot be found while performing an absolute import.
3163 This means that an incorrectly defined __package__ attribute will
3164 now only prevent relative imports in that module rather than causing
3165 all imports from that module to fail.
3166
Nick Coghlan14ff9942008-07-08 14:21:42 +00003167- Issue #2517: Allow unicode messages in Exceptions again by correctly
3168 bypassing the instance dictionary when looking up __unicode__ on
3169 new-style classes.
3170
Amaury Forgeot d'Arcbdd941f2008-07-01 20:38:04 +00003171- Issue #3242: Fix a crash inside the print statement, if sys.stdout is
3172 set to a custom object whose write() method happens to install
3173 another file in sys.stdout.
3174
Amaury Forgeot d'Arc1f40c8a2008-06-30 22:42:40 +00003175- Issue #3088: Corrected a race condition in classes derived from
3176 threading.local: the first member set by a thread could be saved in
3177 another thread's dictionary.
3178
Mark Dickinson1ec2fcd2008-06-20 14:53:43 +00003179- Issue #3004: Minor change to slice.indices(): the start and stop
3180 arguments are now treated identically, making the behaviour easier
3181 to describe and understand. For example, slice(None, -10,
3182 1).indices(9) now returns (0, 0, 1) instead of (0, -1, 1), and
3183 slice(None, 10, -1).indices(10) returns (9, 9, -1) instead of (9,
3184 10, -1).
3185
Georg Brandl278fc502008-07-19 12:46:12 +00003186- Issue #3219: Calling a function with repeated keyword arguments,
3187 f(a=2, a=23), would not cause a syntax error. This was a regression
3188 from 2.4 caused by the switch to the new compiler.
Benjamin Peterson175e4d92008-07-01 19:34:52 +00003189
Georg Brandl278fc502008-07-19 12:46:12 +00003190- Issue #2862: Make int and float freelist management consistent with
3191 other freelists. Changes their CompactFreeList apis into
3192 ClearFreeList apis and calls them via gc.collect().

Thomas Heller57adf222008-08-14 19:10:48 +00003197- Issue #3554: ctypes.string_at and ctypes.wstring_at did call Python
3198 api functions without holding the GIL, which could lead to a fatal
3199 error when they failed.
3200
Martin v. Löwisaabf4042008-08-02 07:20:25 +00003201- Issue #799428: Fix Tkinter.Misc._nametowidget to unwrap Tcl command objects.

3637 mode or even as a 4-way universal binary (that is, PPC, i386,
Georg Brandl5cc774e2008-06-11 20:28:06 +00003638 PPC64 and x86_64 support in one binary).
Ronald Oussoren5640ce22008-06-05 12:58:24 +00003639
3640 This is controlled by the configure argument ``--with-universal-archs``:
3641
3642 - ``--with-universal-archs=all``: install 4-way universal
3643
3644 - ``--with-universal-archs=32-bit``: install 2-way universal, 32-bit (the default)
3645
3646 - ``--with-universal-archs=64-bit``: install 2-way universal, 64-bit
3647
3648 This option should be used in combination with ``--enable-universalsdk=``.

Georg Brandl3ee81df2008-05-17 18:14:43 +00003700- Issue #1631171: Re-implement the 'warnings' module in C (the
3701 original Python code has been kept as backup). This will allow for
3702 using the 'warning's machinery in such places as the parser where
3703 use of pure Python code is not possible. Both the ``showarning()``
3704 and ``formatwarning()`` gain an optional 'line' argument which is
3705 not called by default for backwards-compatibility reasons. Setting
3706 ``warnings.showwarning()`` to an implementation that lacks support
3707 for the ``line`` argument will raise a DeprecationWarning.

3731
Gregory P. Smithd59fefb2008-04-22 08:11:33 +00003732- The getpass module has been improved on Unix. It now uses /dev/tty
3733 by default and uses stderr instead of stdout. A GetPassWarning is
3734 issued when input echo cannot be controlled.
Gregory P. Smith41e30182008-04-21 21:31:08 +00003735

Georg Brandl3ee81df2008-05-17 18:14:43 +00003749- Issue #2513: distutils on Windows is now capable of cross-compiling
Mark Hammond495cf992008-04-07 01:53:39 +00003750 extension modules between 32 and 64 bit platforms. See the distutls

Georg Brandl3ee81df2008-05-17 18:14:43 +00003770- Issue #2550: The approach used by client/server code for obtaining
3771 ports to listen on in network-oriented tests has been refined in an
3772 effort to facilitate running multiple instances of the entire
3773 regression test suite in parallel without issue.
3774 test_support.bind_port() has been fixed such that it will always
3775 return a unique port -- which wasn't always the case with the
3776 previous implementation, especially if socket options had been set
3777 that affected address reuse (i.e. SO_REUSEADDR, SO_REUSEPORT). The
3778 new implementation of bind_port() will actually raise an exception
3779 if it is passed an AF_INET/SOCK_STREAM socket with either the
3780 SO_REUSEADDR or SO_REUSEPORT socket option set. Furthermore, if
3781 available, bind_port() will set the SO_EXCLUSIVEADDRUSE option on
3782 the socket it's been passed. This currently only applies to
3783 Windows. This option prevents any other sockets from binding to the
3784 host/port we've bound to, thus removing the possibility of the
3785 'non-deterministic' behaviour, as Microsoft puts it, that occurs
3786 when a second SOCK_STREAM socket binds and accepts to a host/port
3787 that's already been bound by another socket. The optional preferred
3788 port parameter to bind_port() has been removed. Under no
3789 circumstances should tests be hard coding ports!
3790
3791 test_support.find_unused_port() has also been introduced, which will
3792 pass a temporary socket object to bind_port() in order to obtain an
3793 unused port. The temporary socket object is then closed and
3794 deleted, and the port is returned. This method should only be used
3795 for obtaining an unused port in order to pass to an external program
3796 (i.e. the -accept [port] argument to openssl's s_server mode) or as
3797 a parameter to a server-oriented class that doesn't give you direct
3798 access to the underlying socket used.
3799
3800 Finally, test_support.HOST has been introduced, which should be used
3801 for the host argument of any relevant socket calls (i.e. bind and
3802 connect).
Trent Nelsone41b0062008-04-08 23:47:30 +00003803
3804 The following tests were updated to following the new conventions:
Georg Brandl3ee81df2008-05-17 18:14:43 +00003805 test_socket, test_smtplib, test_asyncore, test_ssl, test_httplib,
Trent Nelsone41b0062008-04-08 23:47:30 +00003806 test_poplib, test_ftplib, test_telnetlib, test_socketserver,
3807 test_asynchat and test_socket_ssl.
3808
Georg Brandl3ee81df2008-05-17 18:14:43 +00003809 It is now possible for multiple instances of the regression test
3810 suite to run in parallel without issue.

4076Core and builtins
4077-----------------
4078
Fred Drakea8ee94b2008-03-01 02:45:07 +00004079- Issue #2051: pyc and pyo files are no longer created with permission
Barry Warsaw52973612008-03-01 02:23:38 +00004080 644. The mode is now inherited from the py file.
Christian Heimes40346852008-02-23 17:52:07 +00004081
Georg Brandlad61bc82008-02-23 15:11:18 +00004082- Issue #2067: file.__exit__() now calls subclasses' close() method.
4083
4084- Patch #1759: Backport of PEP 3129 class decorators.
Christian Heimes5224d282008-02-23 15:01:05 +00004085
Vinay Sajipb7edfc42008-04-02 21:10:23 +00004086- Issue #1881: An internal parser limit has been increased. Also see
Facundo Batistafc2d0102008-02-23 12:01:13 +00004087 issue 215555 for a discussion.
4088
Eric Smitha73fbe72008-02-23 03:09:44 +00004089- Added the future_builtins module, which contains hex() and oct().
4090 These are the PEP 3127 version of these functions, designed to be
4091 compatible with the hex() and oct() builtins from Python 3.0. They
4092 differ slightly in their output formats from the existing, unchanged
4093 Python 2.6 builtins. The expected usage of the future_builtins
4094 module is:
4095 from future_builtins import hex, oct
4096
Eric Smith7ef40bf2008-02-20 23:34:22 +00004097- Issue #1600: Modifed PyOS_ascii_formatd to use at most 2 digit
4098 exponents for exponents with absolute value < 100. Follows C99
4099 standard. This is a change on Windows, which would use 3 digits.
4100 Also, added 'n' to the formats that PyOS_ascii_formatd understands,
4101 so that any alterations it does to the resulting string will be
4102 available in stringlib/formatter.h (for float.__format__).
4103
Eric Smith5a3c1352008-02-19 13:21:56 +00004104- Implemented PEP 3101, Advanced String Formatting. This adds a new
4105 builtin format(); a format() method for str and unicode; a
4106 __format__() method to object, str, unicode, int, long, float, and
4107 datetime; the class string.Formatter; and the C API
4108 PyObject_Format().
4109
Georg Brandl3ee81df2008-05-17 18:14:43 +00004110- Fixed several potential crashes, all caused by specially crafted
4111 __del__ methods exploiting objects in temporarily inconsistent
4112 state.
Amaury Forgeot d'Arc632fad32008-02-16 20:55:24 +00004113
Vinay Sajipb7edfc42008-04-02 21:10:23 +00004114- Issue #2115: Important speedup in setting __slot__ attributes. Also
Georg Brandl3ee81df2008-05-17 18:14:43 +00004115 prevent a possible crash: an Abstract Base Class would try to access
4116 a slot on a registered virtual subclass.
Amaury Forgeot d'Arc60d6c7f2008-02-15 21:22:45 +00004117
Georg Brandl3ee81df2008-05-17 18:14:43 +00004118- Fixed repr() and str() of complex numbers with infinity or nan as
4119 real or imaginary part.
Christian Heimes2f0da532008-02-15 06:57:08 +00004120
Georg Brandl3ee81df2008-05-17 18:14:43 +00004121- Clear all free lists during a gc.collect() of the highest generation
4122 in order to allow pymalloc to free more arenas. Python may give back
4123 memory to the OS earlier.
Christian Heimes3b718a72008-02-14 12:47:33 +00004124
Georg Brandl3ee81df2008-05-17 18:14:43 +00004125- Issue #2045: Fix an infinite recursion triggered when printing a
4126 subclass of collections.defaultdict, if its default_factory is set
4127 to a bound method.
Amaury Forgeot d'Arcb01aa432008-02-08 00:56:02 +00004128
Christian Heimesf75dbef2008-02-08 00:11:31 +00004129- Fixed a minor memory leak in dictobject.c. The content of the free
4130 list was not freed on interpreter shutdown.
4131
Georg Brandl21e99f42010-03-07 15:23:59 +00004132- Limit free list of method and built-in function objects to 256
Georg Brandl3ee81df2008-05-17 18:14:43 +00004133 entries each.
Christian Heimes6075a822008-02-06 12:44:34 +00004134
Georg Brandl3ee81df2008-05-17 18:14:43 +00004135- Patch #1953: Added ``sys._compact_freelists()`` and the C API
4136 functions ``PyInt_CompactFreeList`` and ``PyFloat_CompactFreeList``
Christian Heimes422051a2008-02-04 18:00:12 +00004137 to compact the internal free lists of pre-allocted ints and floats.
4138
Georg Brandl3ee81df2008-05-17 18:14:43 +00004139- Issue #1983: Fixed return type of fork(), fork1() and forkpty()
4140 calls. Python expected the return type int but the fork familie
4141 returns pi_t.
Christian Heimes951cc0f2008-01-31 23:08:23 +00004142
Georg Brandl3ee81df2008-05-17 18:14:43 +00004143- Issue #1678380: Fix a bug that identifies 0j and -0j when they
4144 appear in the same code unit.
Mark Dickinson105be772008-01-31 22:17:37 +00004145
Georg Brandl3ee81df2008-05-17 18:14:43 +00004146- Issue #2025: Add tuple.count() and tuple.index() methods to comply
4147 with the collections.Sequence API.
Raymond Hettinger5b07ebc2008-02-07 00:54:20 +00004148
Georg Brandl3ee81df2008-05-17 18:14:43 +00004149- Patch #1970 by Antoine Pitrou: Speedup unicode whitespace and
4150 linebreak detection
Christian Heimes4d4f2702008-01-30 11:32:37 +00004151
Georg Brandl3ee81df2008-05-17 18:14:43 +00004152- Added ``PyType_ClearCache()`` and ``sys._clear_type_cache`` to clear
4153 the internal lookup cache for ref leak tests.
Christian Heimes908caac2008-01-27 23:34:59 +00004154
Georg Brandl3ee81df2008-05-17 18:14:43 +00004155- Patch #1473257: generator objects gain a gi_code attribute. This is
4156 the same object as the func_code attribute of the function that
4157 produced the generator.
Georg Brandl0cdf9a32008-01-26 14:14:20 +00004158
Georg Brandl3ee81df2008-05-17 18:14:43 +00004159- Issue #1920: "while 0" statements were completely removed by the
4160 compiler, even in the presence of an "else" clause, which is
4161 supposed to be run when the condition is false. Now the compiler
4162 correctly emits bytecode for the "else" suite.
Amaury Forgeot d'Arc31eaafe2008-01-24 22:59:25 +00004163
Guido van Rossumeead05f2008-01-24 18:21:02 +00004164- A few crashers fixed: weakref_in_del.py (issue #1377858);
4165 loosing_dict_ref.py (issue #1303614, test67.py);
4166 borrowed_ref_[34].py (not in tracker).
4167
Vinay Sajipd7cf32e2008-01-24 12:43:33 +00004168- Issue #1069410: The "can't load dll" message box on Windows is
Christian Heimesb2302ba2008-01-23 17:15:06 +00004169 suppressed while an extension is loaded by calling SetErrorMode in
4170 dynload_win.c. The error is still reported properly.
4171
Georg Brandl3ee81df2008-05-17 18:14:43 +00004172- Issue #1915: Python compiles with --enable-unicode=no again. However
Christian Heimes082c9b02008-01-23 14:20:50 +00004173 several extension methods and modules do not work without unicode
4174 support.
4175
Georg Brandl26543b12008-01-21 18:36:51 +00004176- Issue #1882: when compiling code from a string, encoding cookies in the
4177 second line of code were not always recognized correctly.
4178
Georg Brandl14404b62008-01-19 19:27:05 +00004179- Issue #1679: "0x" was taken as a valid integer literal.
4180
Georg Brandl6caad7d2008-01-26 14:19:22 +00004181- Issue #1865: ``bytes`` as an alias for ``str`` and b"" as an alias "" were
Christian Heimes288e89a2008-01-18 18:24:07 +00004182 added.
4183
Christian Heimesc94e2b52008-01-14 04:13:37 +00004184- sys.float_info / PyFloat_GetInfo: The floating point information
4185 object was converted from a dict to a specialized structseq object.
4186
Georg Brandl3ee81df2008-05-17 18:14:43 +00004187- Patch #1816: Added sys.flags structseq. It exposes the status of
4188 most command line arguments and PYTHON* environment variables.
Christian Heimesf31b69f2008-01-14 03:42:48 +00004189
Georg Brandl3ee81df2008-05-17 18:14:43 +00004190- Objects/structseq.c: Implemented new structseq representation. The
4191 patch makes structseqs (e.g. the return value of os.stat) more
4192 readable.
Christian Heimes9c201962008-01-14 03:33:52 +00004193
Georg Brandl3ee81df2008-05-17 18:14:43 +00004194- Patch #1700288: added a type attribute cache that caches method
4195 accesses, resulting in speedups in heavily object-oriented code.
Amaury Forgeot d'Arce4c270c2008-01-14 00:29:41 +00004196
Neal Norwitz3fc15b82008-01-10 05:42:58 +00004197- Bug #1776: __import__() no longer accepts filenames on any platform.
4198 The first parameter to __import__() must be a valid module name.
Christian Heimes3403f152008-01-09 19:56:33 +00004199

4201
Georg Brandl3ee81df2008-05-17 18:14:43 +00004202- Patch #602345: Add -B command line option, PYTHONDONTWRITEBYTECODE
4203 envvar and sys.dont_write_bytecode attribute. All these can be set
4204 to forbid Python to attempt to write compiled bytecode files.
Georg Brandl2da0fce2008-01-07 17:09:35 +00004205
Georg Brandl3ee81df2008-05-17 18:14:43 +00004206- Improve some exception messages when Windows fails to load an
4207 extension module. Now we get for example '%1 is not a valid Win32
4208 application' instead of 'error code 193'.
Amaury Forgeot d'Arce0b76952008-01-04 02:04:15 +00004209
Georg Brandl3ee81df2008-05-17 18:14:43 +00004210- Bug #1481296: Fixed long(float('nan')) != 0L.

Georg Brandl3ee81df2008-05-17 18:14:43 +00004212- Issue #1640: Added math.isinf(x), math.isnan(x) and math.copysign(x,
4213 y) functions.
Christian Heimese2ca4242008-01-03 20:23:15 +00004214
Christian Heimes0a8143f2007-12-18 23:22:54 +00004215- Issue #1635: Platform independent creation and representation of NaN
Georg Brandl3ee81df2008-05-17 18:14:43 +00004216 and INF. float("nan"), float("inf") and float("-inf") now work on
4217 every platform with IEEE 754 semantics.
Christian Heimes0a8143f2007-12-18 23:22:54 +00004218
Georg Brandl3ee81df2008-05-17 18:14:43 +00004219- Compiler now generates simpler and faster code for dictionary
4220 literals. The oparg for BUILD_MAP now indicates an estimated
4221 dictionary size. There is a new opcode, STORE_MAP, for adding
4222 entries to the dictionary.
Raymond Hettingerfd7ed402007-12-18 21:24:09 +00004223
Georg Brandl3ee81df2008-05-17 18:14:43 +00004224- Issue #1638: %zd configure test fails on Linux.

4252 file can now be directly executed by passing their name to the
4253 interpreter. The directory/zipfile is automatically inserted as the
4254 first entry in sys.path.
Nick Coghlan327a39b2007-11-18 11:56:28 +00004255
Georg Brandl3ee81df2008-05-17 18:14:43 +00004256- Issue #1265: Fix a problem with sys.settrace, if the tracing
4257 function uses a generator expression when at the same time the
4258 executed code is closing a paused generator.
Amaury Forgeot d'Arc0d75f092007-11-13 21:54:28 +00004259
Raymond Hettinger1760c8a2007-11-08 02:52:43 +00004260- sets and frozensets now have an isdisjoint() method.
4261

4265
Georg Brandl21e99f42010-03-07 15:23:59 +00004266- The enumerate() built-in function is no longer bounded to sequences
Georg Brandl3ee81df2008-05-17 18:14:43 +00004267 smaller than LONG_MAX. Formerly, it raised an OverflowError. Now,
4268 automatically shifts from ints to longs.
Raymond Hettinger8f669372007-10-03 21:18:11 +00004269
Georg Brandl3ee81df2008-05-17 18:14:43 +00004270- Issue #1686386: Tuple's tp_repr did not take into account the
4271 possibility of having a self-referential tuple, which is possible
4272 from C code. Nor did object's tp_str consider that a type's tp_str
4273 could do something that could lead to an inifinite recursion.
4274 Py_ReprEnter() and Py_EnterRecursiveCall(), respectively, fixed the
4275 issues.

Georg Brandl3ee81df2008-05-17 18:14:43 +00004277- Issue #1164: It was possible to trigger deadlock when using the
4278 'print' statement to write to a file since the GIL was not released
4279 as needed. Now PyObject_Print() does the right thing along with
4280 various tp_print implementations of the built-in types and those in
4281 the collections module.
Brett Cannon01531592007-09-17 03:28:34 +00004282
Georg Brandl3ee81df2008-05-17 18:14:43 +00004283- Issue #1147: Exceptions were directly allowing string exceptions in
4284 their throw() method even though string exceptions no longer
4285 allowed.
Brett Cannon4c20bc42007-09-11 21:02:28 +00004286
Georg Brandl3ee81df2008-05-17 18:14:43 +00004287- Issue #1096: Prevent a segfault from getting the repr of a very
4288 deeply nested list by using the recursion counter.
Brett Cannona0c05512007-09-10 21:38:27 +00004289
Brett Cannon1e534b52007-09-07 04:18:30 +00004290- Issue #1202533: Fix infinite recursion calls triggered by calls to
Georg Brandl3ee81df2008-05-17 18:14:43 +00004291 PyObject_Call() never calling back out to Python code to trigger
4292 recursion depth updates/checks. Required the creation of a static
4293 RuntimeError instance in case normalizing an exception put the
4294 recursion check value past its limit. Fixes crashers
4295 infinite_rec_(1|2|4|5).py.
Brett Cannon1e534b52007-09-07 04:18:30 +00004296
Georg Brandl3ee81df2008-05-17 18:14:43 +00004297- Patch #1031213: Decode source line in SyntaxErrors back to its

4301 with %G.
4302
Georg Brandl3ee81df2008-05-17 18:14:43 +00004303- Prevent expandtabs() on string and unicode objects from causing a

Neal Norwitz0ac60192007-05-27 04:08:54 +00004310- Add new attribute names for function objects. All the func_* become
Georg Brandl3ee81df2008-05-17 18:14:43 +00004311 __*__ attributes. (Some already existed, e.g., __doc__ and
4312 __name__.)
Neal Norwitz0ac60192007-05-27 04:08:54 +00004313
Neal Norwitz8b2bfbc2007-05-23 06:35:32 +00004314- Add -3 option to the interpreter to warn about features that are
4315 deprecated and will be changed/removed in Python 3.0.
4316
Georg Brandl2134e752007-05-21 20:34:16 +00004317- Patch #1686487: you can now pass any mapping after '**' in function
4318 calls.
4319
Collin Winter62903052007-05-18 23:11:24 +00004320- except clauses may now be spelled either "except E, target:" or
Georg Brandl3ee81df2008-05-17 18:14:43 +00004321 "except E as target:". This is to provide forwards compatibility
4322 with Python 3.0.
Collin Winter62903052007-05-18 23:11:24 +00004323
Brett Cannon229cee22007-05-05 01:34:02 +00004324- Deprecate BaseException.message as per PEP 352.
4325
Georg Brandl3ee81df2008-05-17 18:14:43 +00004326- Issue #1303614: don't expose object's __dict__ when the dict is
Georg Brandl21e99f42010-03-07 15:23:59 +00004327 inherited from a built-in base.

Vinay Sajip8549ce32007-05-06 17:53:37 +00004329- When __slots__ are set to a unicode string, make it work the same as
Neal Norwitzcbd9ee62007-04-14 05:25:50 +00004330 setting a plain string, ie don't expand to single letter identifiers.
4331
Raymond Hettinger13936692007-04-11 18:40:58 +00004332- Request #1191699: Slices can now be pickled.
4333
Raymond Hettinger4db5fe92007-04-12 04:10:00 +00004334- Request #1193128: str.translate() now allows a None argument for
4335 translations that only remove characters without re-mapping the
4336 remaining characters.
4337
Georg Brandl5cb76c12007-03-21 09:00:39 +00004338- Patch #1682205: a TypeError while unpacking an iterable is no longer
4339 masked by a generic one with the message "unpack non-sequence".
4340
Neal Norwitzaa754b72007-03-21 06:39:48 +00004341- Remove unused file Python/fmod.c.
4342
Guido van Rossum143b5642007-03-23 04:58:42 +00004343- Bug #1683368: The object.__init__() and object.__new__() methods are
4344 now stricter in rejecting excess arguments. The only time when
4345 either allows excess arguments is when it is not overridden and the
4346 other one is. For backwards compatibility, when both are
4347 overridden, it is a deprecation warning (for now; maybe a Py3k
Guido van Rossum234b1ff2007-03-23 19:39:01 +00004348 warning later). Also, type.__init__() insists on the same signature
4349 as supported by type.__new__().
Guido van Rossum143b5642007-03-23 04:58:42 +00004350
Georg Brandl3ee81df2008-05-17 18:14:43 +00004351- Patch #1675423: PyComplex_AsCComplex() now tries to convert an
4352 object to complex using its __complex__() method before falling back
4353 to the __float__() method. Therefore, the functions in the cmath
4354 module now can operate on objects that define a __complex__()
4355 method.
Georg Brandl2b869942007-03-17 16:08:45 +00004356
Georg Brandl3ee81df2008-05-17 18:14:43 +00004357- Patch #1623563: allow __class__ assignment for classes with
4358 __slots__. The old and the new class are still required to have the
4359 same slot names.

4365 ``object.__reduce_ex__()`` is called with an object that is faking
4366 its type.
Žiga Seilnacht20f43d32007-03-15 11:44:55 +00004367
Georg Brandl3ee81df2008-05-17 18:14:43 +00004368- Patch #1680015: Don't modify __slots__ tuple if it contains an

4372
Georg Brandl7b9c5552007-03-12 14:30:05 +00004373- Bug #1678647: write a newline after printing an exception in any
4374 case, even when converting the value to a string failed.
4375
Georg Brandl871f1bc2007-03-12 13:17:36 +00004376- The dir() function has been extended to call the __dir__() method on
Georg Brandl3ee81df2008-05-17 18:14:43 +00004377 its argument, if it exists. If not, it will work like before. This
4378 allows customizing the output of dir() in the presence of a
4379 __getattr__().

4388 parthensized forms. This means complex(repr(x)) now works instead of
4389 raising a ValueError.
Collin Wintere38051d2007-03-09 20:33:07 +00004390
Georg Brandlaa2321b2007-03-07 00:40:28 +00004391- Patch #703779: unset __file__ in __main__ after running a file. This
Georg Brandl3ee81df2008-05-17 18:14:43 +00004392 makes the filenames the warning module prints much more sensible
4393 when a PYTHONSTARTUP file is used.
Georg Brandlaa2321b2007-03-07 00:40:28 +00004394
Georg Brandl49aafc92007-03-07 00:34:46 +00004395- Variant of patch #697613: don't exit the interpreter on a SystemExit
4396 exception if the -i command line option or PYTHONINSPECT environment
Georg Brandl3ee81df2008-05-17 18:14:43 +00004397 variable is given, but break into the interactive interpreter just
4398 like on other exceptions or normal program exit.

Georg Brandl0fca97a2007-03-05 22:28:08 +00004406- Patch #1674228: when assigning a slice (old-style), check for the
4407 sq_ass_slice instead of the sq_slice slot.
4408
Georg Brandl3ee81df2008-05-17 18:14:43 +00004409- When printing an unraisable error, don't print exceptions. before
4410 the name. This duplicates the behavior whening normally printing
4411 exceptions.

4420 created a weakref on itself during a __del__ call for new-style
4421 classes (classic classes still have the bug).

5020 Python would crash instead of raising an error.

5039 -- the failure just occurred later, with a more cumbersome
5040 exception.

Georg Brandl3ee81df2008-05-17 18:14:43 +00005321- Issue #829951: In the smtplib module, SMTP.starttls() now complies
5322 with RFC 3207 and forgets any knowledge obtained from the server not
5323 obtained from the TLS negotiation itself. Patch contributed by Bill
5324 Fenner.
Gregory P. Smith2b3ba582008-01-17 08:03:17 +00005325
Georg Brandl3ee81df2008-05-17 18:14:43 +00005326- Issue #1339: The smtplib.SMTP class has been refactored a bit such
Gregory P. Smithbde4ae42008-01-17 08:35:49 +00005327 that the SMTP.starttls() caller no longer needs to call ehlo()
5328 beforehand. SMTP.starttls() now raises an exception of the server
Georg Brandl3ee81df2008-05-17 18:14:43 +00005329 does not claim to support starttls. Adds the
5330 SMTP.ehlo_or_helo_if_needed() method. Patch contributed by Bill
5331 Fenner.

5411 complex, tuple, list, dict, set, and frozenset. Formerly, it would
5412 silently miscode subclasses of those types. Now, it raises a
5413 ValueError instead.
Raymond Hettinger12e94202007-11-07 01:13:09 +00005414

Georg Brandl3ee81df2008-05-17 18:14:43 +00005429 time so that opening a database previously created with the DB_DUP
5430 or DB_DUPSORT flag set will keep the proper behavior on subsequent
5431 opens. Specifically: dictionary assignment to a DB object will
5432 replace all values for a given key when the database allows
5433 duplicate values. DB users should use DB.put(k, v) when they want
5434 to store duplicates; not DB[k] = v.
Gregory P. Smithec10a4a2007-11-05 02:32:26 +00005435

5441 characters with ASCII value less than 32. Also, it correctly quotes
5442 dots only if they occur on a single line, as opposed to the previous
5443 behavior of quoting dots if they are the second character of any
5444 line.
Georg Brandl4aef7272007-03-13 22:49:43 +00005445

5767-----
5768
Georg Brandl3ee81df2008-05-17 18:14:43 +00005769- Unified naming convention for free lists and their limits. All free
5770 lists in Object/ are named ``free_list``, the counter ``numfree``
5771 and the upper limit is a macro ``PyName_MAXFREELIST`` inside an
5772 #ifndef block.
Christian Heimes5b970ad2008-02-06 13:33:44 +00005773
Georg Brandl3ee81df2008-05-17 18:14:43 +00005774- ``PySet_Add()`` can now modify a newly created frozenset. Similarly
5775 to ``PyTuple_SetItem``, it can be used to populate a brand new
5776 frozenset; but it does not steal a reference to the added item.

5785
5786- Issue #1534: Added ``PyFloat_GetMax()``, ``PyFloat_GetMin()`` and
5787 ``PyFloat_GetInfo()`` to the float API.
5788
Georg Brandl3ee81df2008-05-17 18:14:43 +00005789- Issue #1521: On 64bit platforms, using PyArgs_ParseTuple with the t#
5790 of w# format code incorrectly truncated the length to an int, even
5791 when PY_SSIZE_T_CLEAN is set. The str.decode method used to return
5792 incorrect results with huge strings.
Georg Brandl6caad7d2008-01-26 14:19:22 +00005793
Georg Brandl3ee81df2008-05-17 18:14:43 +00005794- Issue #1629: Renamed Py_Size, Py_Type and Py_Refcnt to Py_SIZE,

5812- Fix some leftovers from the conversion from int to Py_ssize_t
5813 (relevant to strings and sequences of more than 2**31 items).
5814
5815- Make _PyGILState_NoteThreadState() static, it was not used anywhere
5816 outside of pystate.c and should not be necessary.
5817
Georg Brandl3ee81df2008-05-17 18:14:43 +00005818- ``PyImport_Import`` and ``PyImport_ImportModule`` now always do
5819 absolute imports. In earlier versions they might have used relative
5820 imports under some conditions.
Christian Heimes000a0742008-01-03 22:16:32 +00005821
Georg Brandl3ee81df2008-05-17 18:14:43 +00005822- Added case insensitive comparison methods ``PyOS_stricmp(char*,
5823 char*)`` and ``PyOS_strnicmp(char*, char*, Py_ssize_t)``.
Christian Heimes000a0742008-01-03 22:16:32 +00005824
Georg Brandl3ee81df2008-05-17 18:14:43 +00005825- Bug #1542693: remove semi-colon at end of PyImport_ImportModuleEx

Georg Brandl3ee81df2008-05-17 18:14:43 +00005832- Patch #1706: Drop support for Win9x, WinME and NT4. Python now
5833 requires Windows 2000 or greater. The _WINVER and NTDDI_VERSION
5834 macros are set to Win2k for x86/32bit builds and WinXP for AMD64
5835 builds.
Christian Heimes95d64472008-02-09 19:55:22 +00005836

Georg Brandl3ee81df2008-05-17 18:14:43 +00005850- Removed the macfs module. It had been deprecated since Python 2.5.
5851 This lead to the deprecation of macostools.touched() as it relied
5852 solely on macfs and was a no-op under OS X.
