97 integer format code (one of 'bBhHiIlLqQ'), struct.pack attempts to use the
98 argument's __int__ method to convert to an integer before packing. It also
99 produces a DeprecationWarning in this case. (In Python 2.6, the behaviour
100 was inconsistent: __int__ was used for some integer codes but not for others,
101 and the set of integer codes for which it was used differed between native
102 packing and standard packing.)

290 and read operations on write-only file objects. On Windows, the system C
Georg Brandlba83f822010-03-14 09:50:54 +0000291 library would return a bogus result; on Solaris, it was possible to crash the
292 interpreter. Patch by Stefan Krah.

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

Georg Brandlba83f822010-03-14 09:50:54 +0000310- Issue #7561: Operations on empty bytearrays (such as ``int(bytearray())``)
311 could crash in many places because of the ``PyByteArray_AS_STRING()`` macro
312 returning NULL. The macro now returns a statically allocated empty string
313 instead.

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

Antoine Pitroud840e512010-02-04 20:20:18 +0000355- Issue #4772: Raise a ValueError when an unknown Bluetooth protocol is
Georg Brandlba83f822010-03-14 09:50:54 +0000356 specified, rather than fall through to AF_PACKET (in the ``socket`` module).
Antoine Pitroud840e512010-02-04 20:20:18 +0000357 Also, raise ValueError rather than TypeError when an unknown TIPC address
358 type is specified. Patch by Brian Curtin.

Vinay Sajip28c382f2010-02-04 18:48:53 +0000360- logging: Implemented PEP 391.
361
Antoine Pitrouf3fa0742010-01-31 22:26:04 +0000362- Issue #6939: Fix file I/O objects in the `io` module to keep the original
Georg Brandlba83f822010-03-14 09:50:54 +0000363 file position when calling `truncate()`. It would previously change the file
364 position to the given argument, which goes against the tradition of
Antoine Pitrouf3fa0742010-01-31 22:26:04 +0000365 ftruncate() and other truncation APIs. Patch by Pascal Chambon.
366
Benjamin Petersone06f7112010-01-28 02:15:02 +0000367- UserDict is now a new-style class.
368
Georg Brandlba83f822010-03-14 09:50:54 +0000369- Issue #7610: Reworked implementation of the internal ``zipfile.ZipExtFile``
370 class used to represent files stored inside an archive. The new
371 implementation is significantly faster and can be wrapped in a
372 ``io.BufferedReader`` object for more speedups. It also solves an issue
373 where interleaved calls to ``read()`` and ``readline()`` give wrong results.
374 Patch by Nir Aides.

382 when the release file is empty.
Benjamin Petersona43f34c2010-01-25 03:31:13 +0000383
Georg Brandlba83f822010-03-14 09:50:54 +0000384- Issue #7748: Since unicode values are supported for some metadata options in
385 Distutils, the DistributionMetadata get_* methods will now return an utf-8
386 encoded string for them. This ensures that the upload and register commands
387 send the correct values to PyPI without any error.

Georg Brandlba83f822010-03-14 09:50:54 +0000389- Issue #1670765: Prevent ``email.generator.Generator`` from re-wrapping
R. David Murrayed44dfa2010-01-16 05:15:17 +0000390 headers in multipart/signed MIME parts, which fixes one of the sources of

461Core and Builtins
462-----------------
463
Georg Brandlba83f822010-03-14 09:50:54 +0000464- The ``__complex__()`` method is now looked up on the class of instances to
465 make it consistent with other special methods.
Benjamin Petersonecdae192010-01-04 00:43:01 +0000466
Antoine Pitrou5b7139a2010-01-02 21:12:58 +0000467- Issue #7462: Implement the stringlib fast search algorithm for the `rfind`,
468 `rindex`, `rsplit` and `rpartition` methods. Patch by Florent Xicluna.
469
Mark Dickinson1b34d252010-01-01 17:27:30 +0000470- Issue #5080: A number of functions and methods previously produced a
Georg Brandlba83f822010-03-14 09:50:54 +0000471 DeprecationWarning when passed a float argument where an integer was expected.
472 These functions and methods now raise TypeError instead. The majority of the
473 effects of this change are in the extension modules, but some core functions
474 and methods are affected: notably the 'chr', 'range' and 'xrange' builtins,
475 and many unicode/str methods.

Georg Brandlba83f822010-03-14 09:50:54 +0000488- Issue #1811: Improve accuracy and cross-platform consistency for true division
489 of integers: the result of a/b is now correctly rounded for ints a and b (at
490 least on IEEE 754 platforms), and in particular does not depend on the
491 internal representation of a long.

499
Georg Brandlba83f822010-03-14 09:50:54 +0000500 These executables now work properly with the arch(1) command: ``arch -ppc
501 python`` will start a universal binary version of python in PPC mode (unlike
502 previous releases).

Georg Brandlba83f822010-03-14 09:50:54 +0000658- Issue #7117: ``repr(x)`` for a float x returns a result based on the shortest
659 decimal string that's guaranteed to round back to x under correct rounding
660 (with round-half-to-even rounding mode). Previously it gave a string based on
661 rounding x to 17 decimal digits. repr(x) for a complex number behaves
662 similarly. On platforms where the correctly-rounded strtod and dtoa code is
663 not supported (see below), repr is unchanged.
Mark Dickinsonb678de82009-11-19 18:41:49 +0000664
Georg Brandlba83f822010-03-14 09:50:54 +0000665- Issue #7117: On almost all platforms: float-to-string and string-to-float
666 conversions within Python are now correctly rounded. Places these conversions
667 occur include: str for floats and complex numbers; the float and complex
668 constructors; old-style and new-style numeric formatting; serialization and
669 deserialization of floats and complex numbers using marshal, pickle and json;
670 parsing of float and imaginary literals in Python code; Decimal-to-float
671 conversion.
Mark Dickinsonb678de82009-11-19 18:41:49 +0000672
Georg Brandlba83f822010-03-14 09:50:54 +0000673 The conversions use a Python-adapted version of David Gay's well-known dtoa.c,
674 providing correctly-rounded strtod and dtoa C functions. This code is
675 supported on Windows, and on Unix-like platforms using gcc, icc or suncc as
676 the C compiler. There may be a small number of platforms on which correct
677 operation of this code cannot be guaranteed, so the code is not used: notably,
678 this applies to platforms where the C double format is not IEEE 754 binary64,
679 and to platforms on x86 hardware where the x87 FPU is set to 64-bit precision
680 and Python's configure script is unable to determine how to change the FPU
681 precision. On these platforms conversions use the platform strtod and dtoa,
682 as before.

Georg Brandlba83f822010-03-14 09:50:54 +0000684- Issue #7117: Backport round implementation from Python 3.x. ``round()`` now
685 uses the correctly-rounded string <-> float conversions described above (when
686 available), and so produces correctly rounded results that will display nicely
687 under the float repr. There are two related small changes: (1) round now
688 accepts any class with an ``__index__()`` method for its second argument (but
689 no longer accepts floats for the second argument), and (2) an excessively
690 large second integer argument (e.g., ``round(1.234, 10**100)``) no longer
691 raises an exception.

840 but with at least one decimal point and with a default precision
841 of 12. Previously, the behavior the same but with a default precision of 6.
842 This more closely matches ``str()``, and reduces surprises when adding
843 alignment flags to the empty presentation type. This also affects the new
844 complex.__format__ in the same way.

983
Georg Brandlba83f822010-03-14 09:50:54 +0000984- Issue #1180193: When importing a module from a .pyc (or .pyo) file with an
985 existing .py counterpart, override the co_filename attributes of all code
986 objects if the original filename is obsolete (which can happen if the file has
987 been renamed, moved, or if it is accessed through different paths). Patch by
988 Ziga Seilnacht and Jean-Paul Calderone.

Hirokazu Yamamoto99a1b202009-01-01 15:45:39 +0000992- Issue #4797: IOError.filename was not set when _fileio.FileIO failed to open
993 file with `str' filename on Windows.
994
Antoine Pitrouaa687902009-01-01 14:11:22 +0000995- Issue #3680: Reference cycles created through a dict, set or deque iterator

997
Georg Brandlba83f822010-03-14 09:50:54 +0000998- Issue #4701: PyObject_Hash now implicitly calls PyType_Ready on types where

Nick Coghlan180e4002008-12-30 01:18:48 +00001000
Benjamin Peterson7af65562008-12-29 17:56:58 +00001001- Issue #4764: With io.open, IOError.filename is set when trying to open a
1002 directory on POSIX systems.
1003
Benjamin Petersonfe231b02008-12-29 17:47:42 +00001004- Issue #4764: IOError.filename is set when trying to open a directory on POSIX
1005 systems.
1006
Georg Brandl6425a2f2008-12-28 11:54:53 +00001007- Issue #4759: None is now allowed as the first argument of
Georg Brandlba83f822010-03-14 09:50:54 +00001008 ``bytearray.translate()``. It was always allowed for ``bytes.translate()``.
Georg Brandl6425a2f2008-12-28 11:54:53 +00001009
Skip Montanarof205c132008-12-23 03:30:15 +00001010- Added test case to ensure attempts to read from a file opened for writing
1011 fail.
1012
Georg Brandlba83f822010-03-14 09:50:54 +00001013- Issue #2467: gc.DEBUG_STATS reported invalid elapsed times. Also, always print
1014 elapsed times, not only when some objects are uncollectable/unreachable.

Georg Brandlba83f822010-03-14 09:50:54 +00001027- Issue #4445: Replace ``sizeof(PyStringObject)`` with
1028 ``offsetof(PyStringObject, ob_sval) + 1`` when allocating memory for str
1029 instances. On a typical machine this saves 3 bytes of memory (on average) per
1030 string allocation.
Mark Dickinson826f3fe2008-12-05 21:55:28 +00001031
Amaury Forgeot d'Arcdc619012008-11-22 20:01:18 +00001032- Issue #3996: On Windows, the PyOS_CheckStack function would cause the
1033 interpreter to abort ("Fatal Python error: Could not reset the stack!")
1034 instead of throwing a MemoryError.
1035
Georg Brandlba83f822010-03-14 09:50:54 +00001036- Issue #3689: The list reversed iterator now supports __length_hint__ instead
1037 of __len__. Behavior now matches other reversed iterators.
Raymond Hettinger7989a4d2008-12-03 15:42:10 +00001038
Benjamin Petersonc078f922008-11-21 22:27:24 +00001039- Issue #4367: Python would segfault during compiling when the unicodedata
1040 module couldn't be imported and \N escapes were present.
1041
Georg Brandlba83f822010-03-14 09:50:54 +00001042- Issue #4233: Changed semantic of ``_fileio.FileIO``'s ``close()`` method on
1043 file objects with closefd=False. The file descriptor is still kept open but
1044 the file object behaves like a closed file. The ``FileIO`` object also got a
1045 new readonly attribute ``closefd``.
Amaury Forgeot d'Arc32265652008-11-20 23:34:31 +00001046
Benjamin Peterson46cc6d12008-11-19 21:49:09 +00001047- Issue #4348: Some bytearray methods returned that didn't cause any change to
1048 the bytearray, returned the same bytearray instead of a copy.
1049
Georg Brandlba83f822010-03-14 09:50:54 +00001050- Issue #4317: Fixed a crash in the ``imageop.rgb2rgb8()`` function.

Benjamin Peterson273c2332008-11-17 22:39:09 +00001052- Issue #4230: If ``__getattr__`` is a descriptor, it now functions correctly.
1053
Benjamin Peterson6624a9f2008-11-03 15:14:51 +00001054- Issue #4048: The parser module now correctly validates relative imports.
1055
Benjamin Petersondcee09d2008-10-31 02:16:05 +00001056- Issue #4225: ``from __future__ import unicode_literals`` didn't work in an
1057 exec statement.
1058
Georg Brandlba83f822010-03-14 09:50:54 +00001059- Issue #4176: Fixed a crash when pickling an object which ``__reduce__`` method
1060 does not return iterators for the 4th and 5th items.
Amaury Forgeot d'Arc69a9c5b2008-10-30 21:18:34 +00001061
Benjamin Petersonbdca9422008-10-26 20:21:13 +00001062- Issue #4209: Enabling unicode_literals and the print_function in the same
1063 __future__ import didn't work.
1064
Benjamin Peterson399b1fe2008-10-25 02:53:28 +00001065- Using ``nonlocal`` as a variable name will now raise a Py3k SyntaxWarning
Georg Brandl7fb00ad2008-10-25 07:00:52 +00001066 because it is a reserved word in 3.x.
Benjamin Peterson399b1fe2008-10-25 02:53:28 +00001067
Georg Brandlba83f822010-03-14 09:50:54 +00001068- On windows, ``os.chdir()`` given unicode was not working if
1069 GetCurrentDirectoryW returned a path longer than MAX_PATH. (But It's doubtful
1070 this code path is really executed because I cannot move to such directory on
1071 win2k)
Hirokazu Yamamoto10a018c2008-10-09 10:00:30 +00001072
Georg Brandlba83f822010-03-14 09:50:54 +00001073- Issue #4069: When ``set.remove(element)`` is used with a set element, the
1074 element is temporarily replaced with an equivalent frozenset. But the
1075 eventual KeyError would always report the empty ``frozenset()`` as the missing
1076 key. Now it correctly refers to the initial element.

Georg Brandlba83f822010-03-14 09:50:54 +00001078- Issue #4509: Various issues surrounding resize of bytearray objects to which

Gregory P. Smithae91d092009-03-02 05:13:57 +00001085- The re.sub(), re.subn() and re.split() functions now accept a flags parameter.
1086
Georg Brandlba83f822010-03-14 09:50:54 +00001087- Issue #3845: In PyRun_SimpleFileExFlags avoid invalid memory access with short

Matthias Klose91a3b9e2009-04-05 21:19:13 +00001090- Issue #1113244: Py_XINCREF, Py_DECREF, Py_XDECREF: Add `do { ... } while (0)'
1091 to avoid compiler warnings.

Gregory P. Smith2b3eb372009-04-05 23:48:26 +00001093- Issue #5705: os.setuid() would not accept values > 2**31-1 but pwd.getpwnam()
1094 returned them on 64bit platforms.
1095
Walter Dörwalded960ac2009-05-03 22:36:33 +00001096- Issue #5108: Handle %s like %S and %R in PyUnicode_FromFormatV(): Call
1097 PyUnicode_DecodeUTF8() once, remember the result and output it in a second
1098 step. This avoids problems with counting UTF-8 bytes that ignores the effect
1099 of using the replace error handler in PyUnicode_DecodeUTF8().
1100
Walter Dörwald726ba8e2009-05-06 14:32:35 +00001101- Issue #3739: The unicode-internal encoder now reports the number of characters
1102 consumed like any other encoder (instead of the number of bytes).
1103
Georg Brandlba83f822010-03-14 09:50:54 +00001104- Issue #2422: When compiled with the ``--with-valgrind`` option, the pymalloc
1105 allocator will be automatically disabled when running under Valgrind. This
1106 gives improved memory leak detection when running under Valgrind, while taking
1107 advantage of pymalloc at other times.

Guilherme Polo7f146ab2009-06-21 17:22:50 +00002349- Issue #5450: Moved tests involving loading tk from Lib/test/test_tcl to
2350 Lib/lib-tk/test/test_tkinter/test_loadtk. With this, these tests demonstrate
Georg Brandlba83f822010-03-14 09:50:54 +00002351 the same behaviour as test_ttkguionly (and now also test_tk) which is to skip
2352 the tests if DISPLAY is defined but can't be used.

2360 C and Python implementations in the stdlib can be adjusted to use it over
2361 time.

2370 should cause a test to be skipped are now done using import_module from test
2371 support, which does the conversion.

Martin v. Löwis9fa5a282008-09-11 06:53:30 +00002472- Issue #3642: Suppress warning in obmalloc when size_t is larger than uint.
2473
Amaury Forgeot d'Arc05e34492008-09-10 22:04:45 +00002474- Issue #3743: In a few places, PY_FORMAT_SIZE_T was incorrectly used with
2475 PyString_FromFormat or PyErr_Format to display size_t values. The macro
2476 PY_FORMAT_SIZE_T is designed to select the correct format for the OS
2477 ``printf`` function, whereas PyString_FromFormat has an independent
2478 implementation and uses "%zd" on all platforms for size_t values.
2479 This makes a difference on win64, where ``printf`` needs "%Id" to display
2480 64bit values.

2486 object; previously an int would be returned for small values. the __long__

Vinay Sajip35e3b032008-09-01 14:33:59 +00002496 PyArg_ParseTuple and friends, which occurred when the argument for "s*"
Antoine Pitroud4ae97b2008-08-29 18:39:48 +00002497 was correctly parsed but parsing of subsequent arguments failed.
2498
Vinay Sajip35e3b032008-09-01 14:33:59 +00002499- Issue #2534: speed up isinstance() and issubclass() by 50-70%, so as to
Antoine Pitrou0668c622008-08-26 22:42:08 +00002500 match Python 2.5 speed despite the __instancecheck__ / __subclasscheck__
2501 mechanism. In the process, fix a bug where isinstance() and issubclass(),
2502 when given a tuple of classes as second argument, were looking up
2503 __instancecheck__ / __subclasscheck__ on the tuple rather than on each
2504 type object.
2505
Neal Norwitz18aa3882008-08-24 05:04:52 +00002506- Fix crashes on memory allocation failure found with failmalloc.

Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00002643What's New in Python 2.6 beta 3?
2644================================
2645
Barry Warsaw07a4a382008-08-21 01:15:08 +00002646*Release date: 20-Aug-2008*
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00002647
2648Core and Builtins
2649-----------------
2650
Guido van Rossumf8402962008-08-20 15:01:50 +00002651- Issue #1878: Remove Py_TPFLAGS_HAVE_VERSION_TAG from
2652 Py_TPFLAGS_DEFAULT when not building the core. This means 3rd party
2653 extensions do not automatically benefit from the class attribute
2654 cache; they will have to explicitly add Py_TPFLAGS_HAVE_VERSION_TAG
2655 to their tp_flags field if they care. This is a backwards
2656 compatibility feature; in 3.0, all types will use the cache by
2657 default.
2658
Benjamin Petersonf647dc12008-08-20 01:27:30 +00002659- Keyword arguments can now follow starred arguments. (``f(a, *args,
2660 keyword=23)`` is now valid syntax.)
2661
Thomas Heller0ad5ae02008-08-19 19:25:04 +00002662- ctypes function pointers that are COM methods have a boolean True
2663 value again.
2664
Martin v. Löwisf91d46a2008-08-12 14:49:50 +00002665- Issue #3139: Make buffer-interface thread-safe wrt. PyArg_ParseTuple,
2666 by denying s# to parse objects that have a releasebuffer procedure,
2667 and introducing s*.
2668
Georg Brandl1e13ea92008-08-11 09:07:59 +00002669- Issue #3537: Fix an assertion failure when an empty but presized dict
2670 object was stored in the freelist.
2671
Mark Dickinsonb6467572008-08-04 21:30:09 +00002672- Issue #1481296: Make long(float('nan')) and int(float('nan')) raise
2673 ValueError consistently across platforms.
2674
Amaury Forgeot d'Arc39fd6722008-07-31 21:28:03 +00002675- Issue #3479: On platforms where sizeof(int) is smaller than sizeof(long)
2676 (64bit Unix, for example), unichr() would truncate its argument and return
2677 u'\x00' for unichr(2**32). Now it properly raises an OverflowError.
2678
Neal Norwitze7d8be82008-07-31 17:17:14 +00002679- Apply security patches from Apple.
2680
Amaury Forgeot d'Arc246daed2008-07-31 00:42:16 +00002681- Issue #2542: Now that issubclass() may call arbitrary code, ensure that
2682 PyErr_ExceptionMatches returns 0 when an exception occurs there.
2683
Antoine Pitrou92f82162008-07-25 22:22:08 +00002684- Issue #1819: function calls with several named parameters are now on
2685 average 35% faster (as measured by pybench).
2686
Amaury Forgeot d'Arce4921fe2008-07-21 22:00:38 +00002687- Issue #2378: An unexpected UnboundLocalError or NameError could appear when
2688 the python debugger steps into a class statement: the free variables (local
2689 variables defined in an outer scope) would be deleted from the outer scope.
2690
Gregory P. Smith0470bab2008-07-22 04:46:32 +00002691- Issue #2620: Overflow checking when allocating or reallocating memory
2692 was not always being done properly in some python types and extension
2693 modules. PyMem_MALLOC, PyMem_REALLOC, PyMem_NEW and PyMem_RESIZE have
2694 all been updated to perform better checks and places in the code that
2695 would previously leak memory on the error path when such an allocation
2696 failed have been fixed.
2697
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00002698Library
2699-------
2700
Hirokazu Yamamoto838c79f2008-08-20 13:14:07 +00002701- Issue #3612: Added some missing basic types in ctypes.wintypes.
2702
Benjamin Petersone977ad42008-08-20 01:42:01 +00002703- The methods ``is_in_tuple()``, ``is_vararg()``, and ``is_keywordarg()`` of
2704 symtable.Symbol have been deprecated for removal in 3.0 and the next release.
2705
Amaury Forgeot d'Arc351ffb82008-08-18 19:23:47 +00002706- Issue #2234: distutils failed for some versions of the cygwin compiler. The
2707 version reported by these tools does not necessarily follow the python
2708 version numbering scheme, so the module is less strict when parsing it.
2709
Nick Coghlanf70385a2008-08-18 12:42:46 +00002710- Issue #2235: Added Py3k warnings for types which will become unhashable
2711 under the stricter __hash__ inheritance rules in 3.0. Several types
2712 which did not meet the rules for hash invariants and were already
2713 unhashable in 3.0 have now been explicitly flagged as unhashable in
2714 2.6 as well (collections.Mapping, collections.Set, unittest.TestSuite,
2715 xml.dom.minidom.NamedNodeMap, numbers.Number, UserList.UserList)
2716
Brett Cannon88f801d2008-08-18 00:46:22 +00002717- Update __all__ for cookielib, csv, os, urllib2, and weakref to include things
2718 imported into the module but exposed as part of the module's API.
2719
Brett Cannon7b96f072008-08-18 00:41:11 +00002720- Remove an unneeded import of abc.ABCMeta from 'inspect'.
2721
Brett Cannon46225e72008-08-18 00:36:52 +00002722- Remove unneeded imports of 'sys' and 'warnings' from 'io'.
2723
Brett Cannon25c9d6a2008-08-17 22:10:11 +00002724- Remove unneeded imports of 'warnings' from shelve, filecmp, and dummy_thread.
2725
Hirokazu Yamamoto41a81eb2008-08-17 13:10:46 +00002726- Issue #3575: Incremental decoder's decode function now takes bytearray
2727 by using 's*' instead of 't#'.
2728
Mark Dickinson3e4caeb2009-02-21 20:27:01 +00002729- Issue #2222: Fixed reference leak when occurred os.rename()
Hirokazu Yamamoto7f30a682008-08-17 09:46:56 +00002730 fails unicode conversion on 2nd parameter. (windows only)
2731
Facundo Batista94f243a2008-08-17 03:38:39 +00002732- Issue 2464. urllib2 now supports a malformation in the URL received
2733 in a redirect.
2734
Brett Cannonabe423e2008-08-16 21:47:07 +00002735- Silence the DeprecationWarning raised when importing mimetools in
Brett Cannon721b1452008-08-16 22:00:27 +00002736 BaseHTTPServer, cgi (and rfc822), httplib.
Brett Cannonabe423e2008-08-16 21:47:07 +00002737
Facundo Batistaeb90b782008-08-16 14:44:07 +00002738- Issue #2776: fixed small issue when handling an URL with double slash
2739 after a 302 response in the case of not going through a proxy.
2740
Antoine Pitroub90a8be2008-08-15 21:03:21 +00002741- Issue #2676: in the email package, content-type parsing was hanging on
2742 pathological input because of quadratic or exponential behaviour of a
2743 regular expression.
2744
Antoine Pitrou11ec65d2008-08-14 21:04:30 +00002745- Issue #3476: binary buffered reading through the new "io" library is now
2746 thread-safe.
2747
Brett Cannonbf3157b2008-08-14 05:00:03 +00002748- Silence the DeprecationWarning of rfc822 when it is imported by mimetools
2749 since mimetools itself is deprecated. Because modules are cached, all
2750 subsequent imports of rfc822 will not raise a visible DeprecationWarning.
2751
Antoine Pitrou9fcd4b32008-08-11 17:21:36 +00002752- Issue #3134: shutil referenced undefined WindowsError symbol.
2753
Robert Schuppenies14646332008-08-10 11:01:53 +00002754- Issue #1342811: Fix leak in Tkinter.Menu.delete. Commands associated to
2755 menu entries were not deleted.
2756
Brett Cannon83e81842008-08-09 23:30:55 +00002757- Copied the implementation of reduce() to _functools.reduce() to have a
2758 version that did not raise a DeprecationWarning under -3.
2759
Antoine Pitrou76b8bee2008-08-09 17:27:23 +00002760- Issue #3205: When iterating over a BZ2File fails allocating memory, raise
2761 a MemoryError rather than silently stop the iteration.
2762
Guido van Rossum59ce9012008-08-09 14:55:34 +00002763- Issue #3487: sre "bytecode" validator. Passing invalid "re-bytecode"
2764 to _sre.compile() will now be rejected. This should not affect anybody
2765 since the re.compile() function never generates invalid re-bytecode.
2766
Skip Montanaroa032bf42008-08-08 22:52:51 +00002767- Issue #3436: Make csv.DictReader's fieldnames attribute a property so that
2768 upon first access it can be automatically initialized from the csv file if
2769 it wasn't initialized during instantiation.
2770
Brett Cannon3aa2a492008-08-06 22:28:09 +00002771- Issue #2338: Create imp.reload() to help with transitioning to Python 3.0 as
2772 the reload() built-in has been removed.
2773
Brett Cannon7e30b672008-08-04 21:52:25 +00002774- Changed code in the following modules/packages to remove warnings raised
Brett Cannonc1b76e42008-08-09 23:06:16 +00002775 while running under the ``-3`` flag: aifc, asynchat, asyncore, bdb, bsddb,
Brett Cannon047e4a92008-08-17 04:16:04 +00002776 ConfigParser, cookielib, csv, difflib, distutils, DocXMLRPCServer, email,
2777 filecmp, fileinput, inspect, logging, modulefinder, pdb, pickle, profile,
2778 pstats, pydoc, re, rlcompleter, SimpleXMLRPCServer, shelve, socket,
2779 subprocess, sqlite3, tarfile, Tkinter, test.test_support, textwrap,
2780 threading, tokenize, traceback, urlparse, wsgiref, xml, xmlrpclib.
Brett Cannon7e30b672008-08-04 21:52:25 +00002781
Lars Gustäbel727bd0b2008-08-02 11:26:39 +00002782- Issue #3039: Fix tarfile.TarFileCompat.writestr() which always
2783 raised an AttributeError.
2784
Benjamin Peterson01a24322008-07-28 23:35:27 +00002785- Issue #2523: Fix quadratic behaviour when read()ing a binary file without
Antoine Pitroude781a42008-08-09 12:43:23 +00002786 asking for a specific length. This problem only affected files opened
2787 using the new "io" module, not the built-in open() function.
Benjamin Peterson01a24322008-07-28 23:35:27 +00002788
Mark Dickinsonfe84cce2008-07-27 06:39:07 +00002789- Issue #3449: Update decimal module to use most recent specification
2790 (v. 1.68) and tests (v. 2.58) from IBM.
2791
Skip Montanarof9ac43f2008-07-27 00:50:41 +00002792- Issue 3437: Bug fix in robotparser parsing of Allow: lines.
2793
Raymond Hettinger8c664e82008-07-25 18:43:33 +00002794- Issue 1592: Improve error reporting when operations are attempted

2800
2801- Issue #3303: Fix a crash in locale.strcoll() when calling it with
2802 invalid arguments.
2803
2804- Issue #3302: Fix several crashes when calling locale's gettext functions
2805 with None arguments.
2806
2807- Issue #3389: Allow resolving dotted names for handlers in logging
2808 configuration files.
2809
2810- Deprecate the sunaudio module for removal in Python 3.0.
2811
Antoine Pitrou5fdfa3e2008-07-25 19:42:26 +00002812- Issue #3394: zipfile.writestr sets external attributes when passed a
2813 file name rather than a ZipInfo instance, so files are extracted with
2814 mode 0600 rather than 000 under Unix.
2815
Gregory P. Smitha36f8fe2008-08-04 00:13:29 +00002816- Issue #1857: subprocess.Popen.poll gained an additional _deadstate keyword
2817 argument in python 2.5, this broke code that subclassed Popen to include its
2818 own poll method. Fixed my moving _deadstate to an _internal_poll method.

2826-------------
2827
Nick Coghlan6e8fef02008-08-18 13:14:22 +00002828- Issue #2235: the C API function PyObject_HashNotImplemented and its
2829 interaction with the tp_hash slot (added in 2.6b2) are now documented
2830
Nick Coghlan2a0c2b12008-08-04 12:47:17 +00002831- Issue #643841: The language reference now provides more detailed
2832 coverage of the lookup process for special methods. The disclaimers
2833 regarding lack of coverage of new-style classes have also been
2834 removed, since the coverage is now fairly reasonable.

Raymond Hettingere3ae6552008-06-20 04:18:15 +00002837What's New in Python 2.6 beta 2?
2838================================
2839
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00002840*Release date: 17-Jul-2008*

Raymond Hettingere3ae6552008-06-20 04:18:15 +00002842Core and Builtins
2843-----------------
2844
Georg Brandl3e483f62008-07-16 22:57:41 +00002845- Issue #3156: Fix inconsistent behavior of the bytearray type: all
2846 its methods now allow for items objects that can be converted to
2847 an integer using operator.index().
2848
Mark Dickinson64b7e502008-07-16 09:40:03 +00002849- Issue #3360: Fix incorrect parsing of '020000000000.0', which
2850 produced a ValueError instead of giving the correct float.
2851
Eric Smitha5fa5a22008-07-16 00:11:49 +00002852- Issue #3083: Add alternate (#) formatting for bin, oct, hex output
2853 for str.format(). This adds the prefix 0b, 0o, or 0x, respectively.
2854
Mark Dickinson7103aa42008-07-15 19:08:33 +00002855- Issue #3008: the float type has a new instance method 'float.hex'
2856 and a new class method 'float.fromhex' to convert floating-point
2857 numbers to and from hexadecimal strings, respectively.
2858
Nick Coghlan6d6bd442008-07-15 15:40:22 +00002859- Issue #2235: __hash__ is once again inherited by default. To allow
2860 collections.Hashable to remain meaningful in the presence of the
2861 default hash implementation (object.__hash__), it is now possible
2862 to explicit block inheritance of hash by setting __hash__=None at
2863 the Python level, or tp_hash=PyObject_HashNotImplemented at the C
2864 level.
2865
Nick Coghlanb028f502008-07-13 14:52:36 +00002866- Issue #3221: Issue a RuntimeWarning instead of raising SystemError if
2867 the parent module cannot be found while performing an absolute import.
2868 This means that an incorrectly defined __package__ attribute will
2869 now only prevent relative imports in that module rather than causing
2870 all imports from that module to fail.
2871
Nick Coghlan14ff9942008-07-08 14:21:42 +00002872- Issue #2517: Allow unicode messages in Exceptions again by correctly
2873 bypassing the instance dictionary when looking up __unicode__ on
2874 new-style classes.
2875
Amaury Forgeot d'Arcbdd941f2008-07-01 20:38:04 +00002876- Issue #3242: Fix a crash inside the print statement, if sys.stdout is
2877 set to a custom object whose write() method happens to install
2878 another file in sys.stdout.
2879
Amaury Forgeot d'Arc1f40c8a2008-06-30 22:42:40 +00002880- Issue #3088: Corrected a race condition in classes derived from
2881 threading.local: the first member set by a thread could be saved in
2882 another thread's dictionary.
2883
Mark Dickinson1ec2fcd2008-06-20 14:53:43 +00002884- Issue #3004: Minor change to slice.indices(): the start and stop
2885 arguments are now treated identically, making the behaviour easier
2886 to describe and understand. For example, slice(None, -10,
2887 1).indices(9) now returns (0, 0, 1) instead of (0, -1, 1), and
2888 slice(None, 10, -1).indices(10) returns (9, 9, -1) instead of (9,
2889 10, -1).
2890
Georg Brandl278fc502008-07-19 12:46:12 +00002891- Issue #3219: Calling a function with repeated keyword arguments,
2892 f(a=2, a=23), would not cause a syntax error. This was a regression
2893 from 2.4 caused by the switch to the new compiler.
Benjamin Peterson175e4d92008-07-01 19:34:52 +00002894
Georg Brandl278fc502008-07-19 12:46:12 +00002895- Issue #2862: Make int and float freelist management consistent with
2896 other freelists. Changes their CompactFreeList apis into
2897 ClearFreeList apis and calls them via gc.collect().

Thomas Heller57adf222008-08-14 19:10:48 +00002902- Issue #3554: ctypes.string_at and ctypes.wstring_at did call Python
2903 api functions without holding the GIL, which could lead to a fatal
2904 error when they failed.
2905
Martin v. Löwisaabf4042008-08-02 07:20:25 +00002906- Issue #799428: Fix Tkinter.Misc._nametowidget to unwrap Tcl command objects.

2915 ForkingPickler.register() to resolve conflict with ctypes.
2916
Vinay Sajip51e65192008-07-18 09:01:10 +00002917- Issue #3090: Fixed ARCHFLAGS parsing on OS/X

2920 a valid dlerror() message.
2921
Thomas Heller2bad6572008-07-15 17:19:50 +00002922- Issue #3258: Fixed a crash when a ctypes POINTER type to an
2923 incomplete structure was created.
2924
Brett Cannon3d0b9f02008-07-13 01:15:07 +00002925- Issue #3339: dummy_thread.acquire() should not return None.

Raymond Hettingerb01713e2008-07-10 14:34:57 +00002927- Issue #3285: Fractions from_float() and from_decimal() accept Integral arguments.
2928
Andrew M. Kuchlingcc3f2b12008-07-10 14:43:31 +00002929- Issue #3301: Bisect module behaved badly when lo was negative.

3342 mode or even as a 4-way universal binary (that is, PPC, i386,
Georg Brandl5cc774e2008-06-11 20:28:06 +00003343 PPC64 and x86_64 support in one binary).
Ronald Oussoren5640ce22008-06-05 12:58:24 +00003344
3345 This is controlled by the configure argument ``--with-universal-archs``:
3346
3347 - ``--with-universal-archs=all``: install 4-way universal
3348
3349 - ``--with-universal-archs=32-bit``: install 2-way universal, 32-bit (the default)
3350
3351 - ``--with-universal-archs=64-bit``: install 2-way universal, 64-bit
3352
3353 This option should be used in combination with ``--enable-universalsdk=``.
3354
3355 NOTE: 64-bit and 4-way builds are only suppported on Mac OS X 10.5 (or later).

3392 two handlers that derive the same default base class.
Amaury Forgeot d'Arc96865852008-04-22 21:14:41 +00003393
Christian Heimese74c8f22008-04-19 02:23:57 +00003394- Added kill, terminate and send_signal(sig) to subprocess.Popen.
3395
Georg Brandl3ee81df2008-05-17 18:14:43 +00003396- Added phase(z) -> phi, polar(z) -> r, phi and rect(r, phi) -> z to
3397 the cmath module.
Christian Heimes6f341092008-04-18 23:13:07 +00003398

Georg Brandl3ee81df2008-05-17 18:14:43 +00003405- Issue #1631171: Re-implement the 'warnings' module in C (the
3406 original Python code has been kept as backup). This will allow for
3407 using the 'warning's machinery in such places as the parser where
3408 use of pure Python code is not possible. Both the ``showarning()``
3409 and ``formatwarning()`` gain an optional 'line' argument which is
3410 not called by default for backwards-compatibility reasons. Setting
3411 ``warnings.showwarning()`` to an implementation that lacks support
3412 for the ``line`` argument will raise a DeprecationWarning.

3436
Gregory P. Smithd59fefb2008-04-22 08:11:33 +00003437- The getpass module has been improved on Unix. It now uses /dev/tty
3438 by default and uses stderr instead of stdout. A GetPassWarning is
3439 issued when input echo cannot be controlled.
Gregory P. Smith41e30182008-04-21 21:31:08 +00003440

3452 removed and replaced by pure python code.

Georg Brandl3ee81df2008-05-17 18:14:43 +00003454- Issue #2513: distutils on Windows is now capable of cross-compiling
Mark Hammond495cf992008-04-07 01:53:39 +00003455 extension modules between 32 and 64 bit platforms. See the distutls

Georg Brandl3ee81df2008-05-17 18:14:43 +00003475- Issue #2550: The approach used by client/server code for obtaining
3476 ports to listen on in network-oriented tests has been refined in an
3477 effort to facilitate running multiple instances of the entire
3478 regression test suite in parallel without issue.
3479 test_support.bind_port() has been fixed such that it will always
3480 return a unique port -- which wasn't always the case with the
3481 previous implementation, especially if socket options had been set
3482 that affected address reuse (i.e. SO_REUSEADDR, SO_REUSEPORT). The
3483 new implementation of bind_port() will actually raise an exception
3484 if it is passed an AF_INET/SOCK_STREAM socket with either the
3485 SO_REUSEADDR or SO_REUSEPORT socket option set. Furthermore, if
3486 available, bind_port() will set the SO_EXCLUSIVEADDRUSE option on
3487 the socket it's been passed. This currently only applies to
3488 Windows. This option prevents any other sockets from binding to the
3489 host/port we've bound to, thus removing the possibility of the
3490 'non-deterministic' behaviour, as Microsoft puts it, that occurs
3491 when a second SOCK_STREAM socket binds and accepts to a host/port
3492 that's already been bound by another socket. The optional preferred
3493 port parameter to bind_port() has been removed. Under no
3494 circumstances should tests be hard coding ports!
3495
3496 test_support.find_unused_port() has also been introduced, which will
3497 pass a temporary socket object to bind_port() in order to obtain an
3498 unused port. The temporary socket object is then closed and
3499 deleted, and the port is returned. This method should only be used
3500 for obtaining an unused port in order to pass to an external program
3501 (i.e. the -accept [port] argument to openssl's s_server mode) or as
3502 a parameter to a server-oriented class that doesn't give you direct
3503 access to the underlying socket used.
3504
3505 Finally, test_support.HOST has been introduced, which should be used
3506 for the host argument of any relevant socket calls (i.e. bind and
3507 connect).

3509 The following tests were updated to following the new conventions:
Georg Brandl3ee81df2008-05-17 18:14:43 +00003510 test_socket, test_smtplib, test_asyncore, test_ssl, test_httplib,

3512 test_asynchat and test_socket_ssl.
3513

3515 suite to run in parallel without issue.

3781Core and builtins
3782-----------------
3783
Fred Drakea8ee94b2008-03-01 02:45:07 +00003784- Issue #2051: pyc and pyo files are no longer created with permission
Barry Warsaw52973612008-03-01 02:23:38 +00003785 644. The mode is now inherited from the py file.
Christian Heimes40346852008-02-23 17:52:07 +00003786
Georg Brandlad61bc82008-02-23 15:11:18 +00003787- Issue #2067: file.__exit__() now calls subclasses' close() method.
3788
3789- Patch #1759: Backport of PEP 3129 class decorators.
Christian Heimes5224d282008-02-23 15:01:05 +00003790
Vinay Sajipb7edfc42008-04-02 21:10:23 +00003791- Issue #1881: An internal parser limit has been increased. Also see
Facundo Batistafc2d0102008-02-23 12:01:13 +00003792 issue 215555 for a discussion.
3793
Eric Smitha73fbe72008-02-23 03:09:44 +00003794- Added the future_builtins module, which contains hex() and oct().
3795 These are the PEP 3127 version of these functions, designed to be
3796 compatible with the hex() and oct() builtins from Python 3.0. They
3797 differ slightly in their output formats from the existing, unchanged
3798 Python 2.6 builtins. The expected usage of the future_builtins
3799 module is:
3800 from future_builtins import hex, oct
3801
Eric Smith7ef40bf2008-02-20 23:34:22 +00003802- Issue #1600: Modifed PyOS_ascii_formatd to use at most 2 digit
3803 exponents for exponents with absolute value < 100. Follows C99
3804 standard. This is a change on Windows, which would use 3 digits.
3805 Also, added 'n' to the formats that PyOS_ascii_formatd understands,
3806 so that any alterations it does to the resulting string will be
3807 available in stringlib/formatter.h (for float.__format__).
3808
Eric Smith5a3c1352008-02-19 13:21:56 +00003809- Implemented PEP 3101, Advanced String Formatting. This adds a new
3810 builtin format(); a format() method for str and unicode; a
3811 __format__() method to object, str, unicode, int, long, float, and
3812 datetime; the class string.Formatter; and the C API
3813 PyObject_Format().
3814
Georg Brandl3ee81df2008-05-17 18:14:43 +00003815- Fixed several potential crashes, all caused by specially crafted
3816 __del__ methods exploiting objects in temporarily inconsistent
3817 state.
Amaury Forgeot d'Arc632fad32008-02-16 20:55:24 +00003818
Vinay Sajipb7edfc42008-04-02 21:10:23 +00003819- Issue #2115: Important speedup in setting __slot__ attributes. Also
Georg Brandl3ee81df2008-05-17 18:14:43 +00003820 prevent a possible crash: an Abstract Base Class would try to access
3821 a slot on a registered virtual subclass.
Amaury Forgeot d'Arc60d6c7f2008-02-15 21:22:45 +00003822
Georg Brandl3ee81df2008-05-17 18:14:43 +00003823- Fixed repr() and str() of complex numbers with infinity or nan as
3824 real or imaginary part.
Christian Heimes2f0da532008-02-15 06:57:08 +00003825
Georg Brandl3ee81df2008-05-17 18:14:43 +00003826- Clear all free lists during a gc.collect() of the highest generation
3827 in order to allow pymalloc to free more arenas. Python may give back
3828 memory to the OS earlier.
Christian Heimes3b718a72008-02-14 12:47:33 +00003829
Georg Brandl3ee81df2008-05-17 18:14:43 +00003830- Issue #2045: Fix an infinite recursion triggered when printing a
3831 subclass of collections.defaultdict, if its default_factory is set
3832 to a bound method.
Amaury Forgeot d'Arcb01aa432008-02-08 00:56:02 +00003833
Christian Heimesf75dbef2008-02-08 00:11:31 +00003834- Fixed a minor memory leak in dictobject.c. The content of the free
3835 list was not freed on interpreter shutdown.
3836
Georg Brandl21e99f42010-03-07 15:23:59 +00003837- Limit free list of method and built-in function objects to 256
Georg Brandl3ee81df2008-05-17 18:14:43 +00003838 entries each.
Christian Heimes6075a822008-02-06 12:44:34 +00003839
Georg Brandl3ee81df2008-05-17 18:14:43 +00003840- Patch #1953: Added ``sys._compact_freelists()`` and the C API
3841 functions ``PyInt_CompactFreeList`` and ``PyFloat_CompactFreeList``
Christian Heimes422051a2008-02-04 18:00:12 +00003842 to compact the internal free lists of pre-allocted ints and floats.
3843
Georg Brandl3ee81df2008-05-17 18:14:43 +00003844- Issue #1983: Fixed return type of fork(), fork1() and forkpty()
3845 calls. Python expected the return type int but the fork familie
3846 returns pi_t.
Christian Heimes951cc0f2008-01-31 23:08:23 +00003847
Georg Brandl3ee81df2008-05-17 18:14:43 +00003848- Issue #1678380: Fix a bug that identifies 0j and -0j when they
3849 appear in the same code unit.
Mark Dickinson105be772008-01-31 22:17:37 +00003850
Georg Brandl3ee81df2008-05-17 18:14:43 +00003851- Issue #2025: Add tuple.count() and tuple.index() methods to comply
3852 with the collections.Sequence API.
Raymond Hettinger5b07ebc2008-02-07 00:54:20 +00003853
Georg Brandl3ee81df2008-05-17 18:14:43 +00003854- Patch #1970 by Antoine Pitrou: Speedup unicode whitespace and
3855 linebreak detection
Christian Heimes4d4f2702008-01-30 11:32:37 +00003856
Georg Brandl3ee81df2008-05-17 18:14:43 +00003857- Added ``PyType_ClearCache()`` and ``sys._clear_type_cache`` to clear
3858 the internal lookup cache for ref leak tests.
Christian Heimes908caac2008-01-27 23:34:59 +00003859
Georg Brandl3ee81df2008-05-17 18:14:43 +00003860- Patch #1473257: generator objects gain a gi_code attribute. This is
3861 the same object as the func_code attribute of the function that
3862 produced the generator.
Georg Brandl0cdf9a32008-01-26 14:14:20 +00003863
Georg Brandl3ee81df2008-05-17 18:14:43 +00003864- Issue #1920: "while 0" statements were completely removed by the
3865 compiler, even in the presence of an "else" clause, which is
3866 supposed to be run when the condition is false. Now the compiler
3867 correctly emits bytecode for the "else" suite.
Amaury Forgeot d'Arc31eaafe2008-01-24 22:59:25 +00003868
Guido van Rossumeead05f2008-01-24 18:21:02 +00003869- A few crashers fixed: weakref_in_del.py (issue #1377858);
3870 loosing_dict_ref.py (issue #1303614, test67.py);
3871 borrowed_ref_[34].py (not in tracker).
3872
Vinay Sajipd7cf32e2008-01-24 12:43:33 +00003873- Issue #1069410: The "can't load dll" message box on Windows is
Christian Heimesb2302ba2008-01-23 17:15:06 +00003874 suppressed while an extension is loaded by calling SetErrorMode in
3875 dynload_win.c. The error is still reported properly.
3876
Georg Brandl3ee81df2008-05-17 18:14:43 +00003877- Issue #1915: Python compiles with --enable-unicode=no again. However
Christian Heimes082c9b02008-01-23 14:20:50 +00003878 several extension methods and modules do not work without unicode
3879 support.
3880
Georg Brandl26543b12008-01-21 18:36:51 +00003881- Issue #1882: when compiling code from a string, encoding cookies in the
3882 second line of code were not always recognized correctly.
3883
Georg Brandl14404b62008-01-19 19:27:05 +00003884- Issue #1679: "0x" was taken as a valid integer literal.
3885
Georg Brandl6caad7d2008-01-26 14:19:22 +00003886- Issue #1865: ``bytes`` as an alias for ``str`` and b"" as an alias "" were
Christian Heimes288e89a2008-01-18 18:24:07 +00003887 added.
3888
Christian Heimesc94e2b52008-01-14 04:13:37 +00003889- sys.float_info / PyFloat_GetInfo: The floating point information
3890 object was converted from a dict to a specialized structseq object.
3891
Georg Brandl3ee81df2008-05-17 18:14:43 +00003892- Patch #1816: Added sys.flags structseq. It exposes the status of
3893 most command line arguments and PYTHON* environment variables.
Christian Heimesf31b69f2008-01-14 03:42:48 +00003894
Georg Brandl3ee81df2008-05-17 18:14:43 +00003895- Objects/structseq.c: Implemented new structseq representation. The
3896 patch makes structseqs (e.g. the return value of os.stat) more
3897 readable.
Christian Heimes9c201962008-01-14 03:33:52 +00003898
Georg Brandl3ee81df2008-05-17 18:14:43 +00003899- Patch #1700288: added a type attribute cache that caches method
3900 accesses, resulting in speedups in heavily object-oriented code.
Amaury Forgeot d'Arce4c270c2008-01-14 00:29:41 +00003901
Neal Norwitz3fc15b82008-01-10 05:42:58 +00003902- Bug #1776: __import__() no longer accepts filenames on any platform.
3903 The first parameter to __import__() must be a valid module name.
Christian Heimes3403f152008-01-09 19:56:33 +00003904
Georg Brandlaed6c662008-01-07 17:25:53 +00003905- Patch #1668: renamed THREADDEBUG envvar to PYTHONTHREADDEBUG.
3906
Georg Brandl3ee81df2008-05-17 18:14:43 +00003907- Patch #602345: Add -B command line option, PYTHONDONTWRITEBYTECODE
3908 envvar and sys.dont_write_bytecode attribute. All these can be set
3909 to forbid Python to attempt to write compiled bytecode files.
Georg Brandl2da0fce2008-01-07 17:09:35 +00003910
Georg Brandl3ee81df2008-05-17 18:14:43 +00003911- Improve some exception messages when Windows fails to load an
3912 extension module. Now we get for example '%1 is not a valid Win32
3913 application' instead of 'error code 193'.
Amaury Forgeot d'Arce0b76952008-01-04 02:04:15 +00003914
Georg Brandl3ee81df2008-05-17 18:14:43 +00003915- Bug #1481296: Fixed long(float('nan')) != 0L.

Georg Brandl3ee81df2008-05-17 18:14:43 +00003917- Issue #1640: Added math.isinf(x), math.isnan(x) and math.copysign(x,
3918 y) functions.
Christian Heimese2ca4242008-01-03 20:23:15 +00003919
Christian Heimes0a8143f2007-12-18 23:22:54 +00003920- Issue #1635: Platform independent creation and representation of NaN
Georg Brandl3ee81df2008-05-17 18:14:43 +00003921 and INF. float("nan"), float("inf") and float("-inf") now work on
3922 every platform with IEEE 754 semantics.
Christian Heimes0a8143f2007-12-18 23:22:54 +00003923
Georg Brandl3ee81df2008-05-17 18:14:43 +00003924- Compiler now generates simpler and faster code for dictionary
3925 literals. The oparg for BUILD_MAP now indicates an estimated
3926 dictionary size. There is a new opcode, STORE_MAP, for adding
3927 entries to the dictionary.
Raymond Hettingerfd7ed402007-12-18 21:24:09 +00003928
Georg Brandl3ee81df2008-05-17 18:14:43 +00003929- Issue #1638: %zd configure test fails on Linux.

3939
Nick Coghlanef01d822007-12-03 12:55:17 +00003940- PEP 366: Allow explicit relative imports when executing modules
3941 inside packages with the -m switch via a new module level
3942 __package__ attribute.
3943
Georg Brandl3ee81df2008-05-17 18:14:43 +00003944- Issue #1402: Fix a crash on exit, when another thread is still
3945 running, and if the deallocation of its frames somehow calls the
3946 PyGILState_Ensure() / PyGILState_Release() functions.
Amaury Forgeot d'Arcbe49a902007-11-30 20:37:22 +00003947

3957 file can now be directly executed by passing their name to the
3958 interpreter. The directory/zipfile is automatically inserted as the
3959 first entry in sys.path.
Nick Coghlan327a39b2007-11-18 11:56:28 +00003960
Georg Brandl3ee81df2008-05-17 18:14:43 +00003961- Issue #1265: Fix a problem with sys.settrace, if the tracing
3962 function uses a generator expression when at the same time the
3963 executed code is closing a paused generator.
Amaury Forgeot d'Arc0d75f092007-11-13 21:54:28 +00003964
Raymond Hettinger1760c8a2007-11-08 02:52:43 +00003965- sets and frozensets now have an isdisjoint() method.
3966
Raymond Hettinger3f8caa32007-10-24 01:28:33 +00003967- optimize the performance of builtin.sum().

Neal Norwitz44f326e2007-10-05 05:29:17 +00003969- Fix warnings found by the new version of the Coverity checker.
3970
Georg Brandl21e99f42010-03-07 15:23:59 +00003971- The enumerate() built-in function is no longer bounded to sequences
Georg Brandl3ee81df2008-05-17 18:14:43 +00003972 smaller than LONG_MAX. Formerly, it raised an OverflowError. Now,
3973 automatically shifts from ints to longs.
Raymond Hettinger8f669372007-10-03 21:18:11 +00003974
Georg Brandl3ee81df2008-05-17 18:14:43 +00003975- Issue #1686386: Tuple's tp_repr did not take into account the
3976 possibility of having a self-referential tuple, which is possible
3977 from C code. Nor did object's tp_str consider that a type's tp_str
3978 could do something that could lead to an inifinite recursion.
3979 Py_ReprEnter() and Py_EnterRecursiveCall(), respectively, fixed the
3980 issues.
Brett Cannon0b14f242007-09-30 19:45:10 +00003981
Georg Brandl3ee81df2008-05-17 18:14:43 +00003982- Issue #1164: It was possible to trigger deadlock when using the
3983 'print' statement to write to a file since the GIL was not released
3984 as needed. Now PyObject_Print() does the right thing along with

Georg Brandl3ee81df2008-05-17 18:14:43 +00003988- Issue #1147: Exceptions were directly allowing string exceptions in
3989 their throw() method even though string exceptions no longer
3990 allowed.

Georg Brandl3ee81df2008-05-17 18:14:43 +00003992- Issue #1096: Prevent a segfault from getting the repr of a very
3993 deeply nested list by using the recursion counter.
Brett Cannona0c05512007-09-10 21:38:27 +00003994
Brett Cannon1e534b52007-09-07 04:18:30 +00003995- Issue #1202533: Fix infinite recursion calls triggered by calls to
Georg Brandl3ee81df2008-05-17 18:14:43 +00003996 PyObject_Call() never calling back out to Python code to trigger
3997 recursion depth updates/checks. Required the creation of a static
3998 RuntimeError instance in case normalizing an exception put the
3999 recursion check value past its limit. Fixes crashers
4000 infinite_rec_(1|2|4|5).py.
Brett Cannon1e534b52007-09-07 04:18:30 +00004001

Neal Norwitz0ac60192007-05-27 04:08:54 +00004015- Add new attribute names for function objects. All the func_* become
Georg Brandl3ee81df2008-05-17 18:14:43 +00004016 __*__ attributes. (Some already existed, e.g., __doc__ and
4017 __name__.)
Neal Norwitz0ac60192007-05-27 04:08:54 +00004018
Neal Norwitz8b2bfbc2007-05-23 06:35:32 +00004019- Add -3 option to the interpreter to warn about features that are

4023 calls.
4024
Collin Winter62903052007-05-18 23:11:24 +00004025- except clauses may now be spelled either "except E, target:" or
Georg Brandl3ee81df2008-05-17 18:14:43 +00004026 "except E as target:". This is to provide forwards compatibility
4027 with Python 3.0.
Collin Winter62903052007-05-18 23:11:24 +00004028
Brett Cannon229cee22007-05-05 01:34:02 +00004029- Deprecate BaseException.message as per PEP 352.
4030
Georg Brandl3ee81df2008-05-17 18:14:43 +00004031- Issue #1303614: don't expose object's __dict__ when the dict is
Georg Brandl21e99f42010-03-07 15:23:59 +00004032 inherited from a built-in base.

Vinay Sajip8549ce32007-05-06 17:53:37 +00004034- When __slots__ are set to a unicode string, make it work the same as
Neal Norwitzcbd9ee62007-04-14 05:25:50 +00004035 setting a plain string, ie don't expand to single letter identifiers.
4036
Raymond Hettinger13936692007-04-11 18:40:58 +00004037- Request #1191699: Slices can now be pickled.
4038
Raymond Hettinger4db5fe92007-04-12 04:10:00 +00004039- Request #1193128: str.translate() now allows a None argument for
4040 translations that only remove characters without re-mapping the
4041 remaining characters.
4042
Georg Brandl5cb76c12007-03-21 09:00:39 +00004043- Patch #1682205: a TypeError while unpacking an iterable is no longer

4047
Guido van Rossum143b5642007-03-23 04:58:42 +00004048- Bug #1683368: The object.__init__() and object.__new__() methods are
4049 now stricter in rejecting excess arguments. The only time when
4050 either allows excess arguments is when it is not overridden and the
4051 other one is. For backwards compatibility, when both are
4052 overridden, it is a deprecation warning (for now; maybe a Py3k
Guido van Rossum234b1ff2007-03-23 19:39:01 +00004053 warning later). Also, type.__init__() insists on the same signature
4054 as supported by type.__new__().
Guido van Rossum143b5642007-03-23 04:58:42 +00004055
Georg Brandl3ee81df2008-05-17 18:14:43 +00004056- Patch #1675423: PyComplex_AsCComplex() now tries to convert an
4057 object to complex using its __complex__() method before falling back
4058 to the __float__() method. Therefore, the functions in the cmath
4059 module now can operate on objects that define a __complex__()
4060 method.
Georg Brandl2b869942007-03-17 16:08:45 +00004061
Georg Brandl3ee81df2008-05-17 18:14:43 +00004062- Patch #1623563: allow __class__ assignment for classes with
4063 __slots__. The old and the new class are still required to have the
4064 same slot names.

4071 its type.
Žiga Seilnacht20f43d32007-03-15 11:44:55 +00004072
Georg Brandl3ee81df2008-05-17 18:14:43 +00004073- Patch #1680015: Don't modify __slots__ tuple if it contains an

4077
Georg Brandl7b9c5552007-03-12 14:30:05 +00004078- Bug #1678647: write a newline after printing an exception in any
4079 case, even when converting the value to a string failed.
4080
Georg Brandl871f1bc2007-03-12 13:17:36 +00004081- The dir() function has been extended to call the __dir__() method on
Georg Brandl3ee81df2008-05-17 18:14:43 +00004082 its argument, if it exists. If not, it will work like before. This
4083 allows customizing the output of dir() in the presence of a
4084 __getattr__().
Georg Brandl871f1bc2007-03-12 13:17:36 +00004085
Collin Winter276887b2007-03-12 16:11:39 +00004086- Patch #922167: Python no longer segfaults when faced with infinitely
4087 self-recursive reload() calls (as reported by bug #742342).

4093 parthensized forms. This means complex(repr(x)) now works instead of
4094 raising a ValueError.
Collin Wintere38051d2007-03-09 20:33:07 +00004095
Georg Brandlaa2321b2007-03-07 00:40:28 +00004096- Patch #703779: unset __file__ in __main__ after running a file. This
Georg Brandl3ee81df2008-05-17 18:14:43 +00004097 makes the filenames the warning module prints much more sensible
4098 when a PYTHONSTARTUP file is used.
Georg Brandlaa2321b2007-03-07 00:40:28 +00004099

4101 exception if the -i command line option or PYTHONINSPECT environment
Georg Brandl3ee81df2008-05-17 18:14:43 +00004102 variable is given, but break into the interactive interpreter just
4103 like on other exceptions or normal program exit.

Georg Brandl0fca97a2007-03-05 22:28:08 +00004111- Patch #1674228: when assigning a slice (old-style), check for the
4112 sq_ass_slice instead of the sq_slice slot.
4113
Georg Brandl3ee81df2008-05-17 18:14:43 +00004114- When printing an unraisable error, don't print exceptions. before
4115 the name. This duplicates the behavior whening normally printing
4116 exceptions.

4725 Python would crash instead of raising an error.
4726
Thomas Hellerc2f77252007-03-09 19:21:28 +00004727- Bug #1646630: ctypes.string_at(buf, 0) and ctypes.wstring_at(buf, 0)
4728 returned string up to the first NUL character.

4739
Georg Brandl3ee81df2008-05-17 18:14:43 +00004740- unittest now verifies more of its assumptions. In particular,
4741 TestCase and TestSuite subclasses (not instances) are no longer
4742 accepted in TestSuite.addTest(). This should cause no
4743 incompatibility since it never made sense with ordinary subclasses
4744 -- the failure just occurred later, with a more cumbersome
4745 exception.

5029 Fenner.
Gregory P. Smith2b3ba582008-01-17 08:03:17 +00005030
Georg Brandl3ee81df2008-05-17 18:14:43 +00005031- Issue #1339: The smtplib.SMTP class has been refactored a bit such
Gregory P. Smithbde4ae42008-01-17 08:35:49 +00005032 that the SMTP.starttls() caller no longer needs to call ehlo()
5033 beforehand. SMTP.starttls() now raises an exception of the server
Georg Brandl3ee81df2008-05-17 18:14:43 +00005034 does not claim to support starttls. Adds the
5035 SMTP.ehlo_or_helo_if_needed() method. Patch contributed by Bill

5116 complex, tuple, list, dict, set, and frozenset. Formerly, it would
5117 silently miscode subclasses of those types. Now, it raises a

Georg Brandl3ee81df2008-05-17 18:14:43 +00005134 time so that opening a database previously created with the DB_DUP
5135 or DB_DUPSORT flag set will keep the proper behavior on subsequent
5136 opens. Specifically: dictionary assignment to a DB object will
5137 replace all values for a given key when the database allows
5138 duplicate values. DB users should use DB.put(k, v) when they want
5139 to store duplicates; not DB[k] = v.
Gregory P. Smithec10a4a2007-11-05 02:32:26 +00005140

5146 characters with ASCII value less than 32. Also, it correctly quotes
5147 dots only if they occur on a single line, as opposed to the previous
5148 behavior of quoting dots if they are the second character of any
5149 line.

5472-----
5473
Georg Brandl3ee81df2008-05-17 18:14:43 +00005474- Unified naming convention for free lists and their limits. All free
5475 lists in Object/ are named ``free_list``, the counter ``numfree``
5476 and the upper limit is a macro ``PyName_MAXFREELIST`` inside an
5477 #ifndef block.
Christian Heimes5b970ad2008-02-06 13:33:44 +00005478
Georg Brandl3ee81df2008-05-17 18:14:43 +00005479- ``PySet_Add()`` can now modify a newly created frozenset. Similarly
5480 to ``PyTuple_SetItem``, it can be used to populate a brand new
5481 frozenset; but it does not steal a reference to the added item.
Amaury Forgeot d'Arccab3d982008-02-03 22:51:43 +00005482
Vinay Sajipb7edfc42008-04-02 21:10:23 +00005483- Added ``PySet_Check()`` and ``PyFrozenSet_Check()`` to the set API.

Georg Brandl3ee81df2008-05-17 18:14:43 +00005485- Backport of PyUnicode_FromString(), _FromStringAndSize(), _Format
5486 and _FormatV from Python 3.0. Made PyLong_AsSsize_t and
5487 PyLong_FromSsize_t public functions.
Georg Brandl6caad7d2008-01-26 14:19:22 +00005488
5489- Patch #1720595: add T_BOOL to the range of structmember types.
5490
5491- Issue #1534: Added ``PyFloat_GetMax()``, ``PyFloat_GetMin()`` and
5492 ``PyFloat_GetInfo()`` to the float API.
5493
Georg Brandl3ee81df2008-05-17 18:14:43 +00005494- Issue #1521: On 64bit platforms, using PyArgs_ParseTuple with the t#
5495 of w# format code incorrectly truncated the length to an int, even
5496 when PY_SSIZE_T_CLEAN is set. The str.decode method used to return
5497 incorrect results with huge strings.
Georg Brandl6caad7d2008-01-26 14:19:22 +00005498
Georg Brandl3ee81df2008-05-17 18:14:43 +00005499- Issue #1629: Renamed Py_Size, Py_Type and Py_Refcnt to Py_SIZE,
5500 Py_TYPE and Py_REFCNT.
Georg Brandl6caad7d2008-01-26 14:19:22 +00005501
Georg Brandl3ee81df2008-05-17 18:14:43 +00005502- PEP 3123: Provide forward compatibility with Python 3.0, while
5503 keeping backwards compatibility. Add Py_Refcnt, Py_Type, Py_Size,
5504 and PyVarObject_HEAD_INIT.
Georg Brandl6caad7d2008-01-26 14:19:22 +00005505
Georg Brandl3ee81df2008-05-17 18:14:43 +00005506- Py_ssize_t fields work in structmember when HAVE_LONG_LONG is not
5507 defined.
Georg Brandl6caad7d2008-01-26 14:19:22 +00005508
5509- Patch #1733960: Allow T_LONGLONG to accept ints.
5510
5511- T_PYSSIZET can now be used in PyMemberDef lists for Py_ssize_t members.
5512

5516
5517- Fix some leftovers from the conversion from int to Py_ssize_t
5518 (relevant to strings and sequences of more than 2**31 items).
5519
5520- Make _PyGILState_NoteThreadState() static, it was not used anywhere
5521 outside of pystate.c and should not be necessary.
5522
Georg Brandl3ee81df2008-05-17 18:14:43 +00005523- ``PyImport_Import`` and ``PyImport_ImportModule`` now always do
5524 absolute imports. In earlier versions they might have used relative
5525 imports under some conditions.
Christian Heimes000a0742008-01-03 22:16:32 +00005526
Georg Brandl3ee81df2008-05-17 18:14:43 +00005527- Added case insensitive comparison methods ``PyOS_stricmp(char*,
5528 char*)`` and ``PyOS_strnicmp(char*, char*, Py_ssize_t)``.
Christian Heimes000a0742008-01-03 22:16:32 +00005529
Georg Brandl3ee81df2008-05-17 18:14:43 +00005530- Bug #1542693: remove semi-colon at end of PyImport_ImportModuleEx
5531 macro so it can be used as an expression.

5536
Georg Brandl3ee81df2008-05-17 18:14:43 +00005537- Patch #1706: Drop support for Win9x, WinME and NT4. Python now
5538 requires Windows 2000 or greater. The _WINVER and NTDDI_VERSION
5539 macros are set to Win2k for x86/32bit builds and WinXP for AMD64
5540 builds.
Christian Heimes95d64472008-02-09 19:55:22 +00005541
Georg Brandl3ee81df2008-05-17 18:14:43 +00005542- Conditionalize definition of _CRT_SECURE_NO_DEPRECATE and

Georg Brandl3ee81df2008-05-17 18:14:43 +00005555- Removed the macfs module. It had been deprecated since Python 2.5.
5556 This lead to the deprecation of macostools.touched() as it relied
5557 solely on macfs and was a no-op under OS X.
