33 filename and date, conforming to the 'standards' they were originally
34 designed to follow. This improves compatibility with patch tools.
35
R. David Murray27ef9372010-04-12 14:26:06 +000036- Issue #7472: Fixed typo in email.encoders module; messages using ISO-2022
37 character sets will now consistently use a Content-Transfer-Encoding of

51Core and Builtins
52-----------------
53
Philip Jenveyaebbaeb2010-04-06 23:24:45 +000054- Issue #7301: Add environment variable $PYTHONWARNINGS.
55
Benjamin Peterson3a1dfa22010-04-06 21:50:00 +000056- Issue #8329: Don't return the same lists from select.select when no fds are
57 changed.
58
Mark Dickinson82791672010-04-06 16:47:55 +000059- Issue #8259: 1L << (2**31) no longer produces an 'outrageous shift error'
60 on 64-bit machines. The shift count for either left or right shift is
61 permitted to be up to sys.maxsize.
62
Benjamin Peterson4ceeeb02010-04-03 22:48:51 +000063- Ensure that tokenization of identifiers is not affected by locale.
64
Tarek Ziadé00002952010-04-03 08:37:59 +000065- Issue #1222585: Added LDCXXSHARED for C++ support. Patch by Arfrever.

68
Eric Smithd44b2fc2010-04-02 12:30:56 +000069- Issue #7994: Issue a PendingDeprecationWarning if object.__format__
70 is called with a non-empty format string. This is an effort to
71 future-proof user code. If a derived class does not currently
72 implement __format__ but later adds its own __format__, it would
73 most likely break user code that had supplied a format string. This
74 will be changed to a DeprecationWaring in Python 3.3 and it will be
75 an error in Python 3.4.
76
Antoine Pitroua57df2c2010-03-31 21:32:15 +000077- Issue #8268: Old-style classes (not just instances) now support weak
78 references.

103 using the new attributes `ssl.OPENSSL_VERSION`, `ssl.OPENSSL_VERSION_INFO`
104 and `ssl.OPENSSL_VERSION_NUMBER`.
105
Benjamin Peterson76a23c12010-04-04 23:23:22 +0000106- Issue #8310: Allow dis to examine new style classes.
107
Mark Dickinson8a950712010-04-03 15:47:46 +0000108- Issue #8257: The Decimal construct now accepts a float instance
109 directly, converting that float to a Decimal of equal value:
110
111 >>> Decimal(1.1)
112 Decimal('1.100000000000000088817841970012523233890533447265625')

Raymond Hettinger34c35b22010-04-03 10:22:00 +0000114- collections.Counter() now supports a subtract() method.
115
Raymond Hettingera551f312010-04-04 18:34:45 +0000116- the functools module now has a total_ordering() class decorator
Georg Brandl4fabac52010-04-14 08:53:38 +0000117 to simplify the specification of rich comparisons.
Raymond Hettingera551f312010-04-04 18:34:45 +0000118
Raymond Hettingerbb006cf2010-04-04 21:45:01 +0000119- The functools module also adds cmp_to_key() as a tool to transition
Raymond Hettingera551f312010-04-04 18:34:45 +0000120 old-style comparison functions to new-style key-functions.

Mark Dickinson7c63eee2010-04-02 22:27:36 +0000122- Issue #8294: The Fraction constructor now accepts Decimal and float
123 instances directly.
124
Mark Dickinsone096e822010-04-02 10:17:07 +0000125- Issue #7279: Comparisons involving a Decimal signaling NaN now
126 signal InvalidOperation instead of returning False. (Comparisons
Mark Dickinsonf3eeca12010-04-02 10:35:12 +0000127 involving a quiet NaN are unchanged.) Also, Decimal quiet NaNs
128 are now hashable; Decimal signaling NaNs remain unhashable.
Mark Dickinsone096e822010-04-02 10:17:07 +0000129
Mark Dickinson99d80962010-04-02 08:53:22 +0000130- Issue #2531: Comparison operations between floats and Decimal
131 instances now return a result based on the numeric values of the
132 operands; previously they returned an arbitrary result based on
133 the relative ordering of id(float) and id(Decimal).
134
Barry Warsawf7f2d6f2010-03-31 21:07:16 +0000135- Issue #8233: When run as a script, py_compile.py optionally takes a single
136 argument `-` which tells it to read files to compile from stdin. Each line
137 is read on demand and the named file is compiled immediately. (Original
138 patch by Piotr Ożarowski).
139
140- Issue #3135: Add inspect.getcallargs, which binds arguments to a function
141 like a normal call.
Benjamin Peterson7e213252010-03-30 17:58:13 +0000142
Florent Xicluna58b65662010-03-30 16:29:03 +0000143- Backwards incompatible change: Unicode codepoints line tabulation (0x0B) and
144 form feed (0x0C) are now considered linebreaks, as specified in Unicode
145 Standard Annex #14. See issue #7643.

147
Mark Dickinson9588d992010-03-27 11:14:37 +0000148- Comparisons using one of <, <=, >, >= between a complex instance and
149 a Fractions instance now raise TypeError instead of returning
150 True/False. This makes Fraction <=> complex comparisons consistent with
151 int <=> complex, float <=> complex, and complex <=> complex comparisons.
152
Michael Foorde6410c52010-03-29 20:04:23 +0000153- Addition of ``WeakSet`` to the ``weakref`` module.

164 now silenced.
165
Florent Xicluna9e7a4c92010-03-22 16:07:38 +0000166- Issue #7703: ctypes supports both buffer() and memoryview(). The former is

173 method to LoggerAdapter.
174
Vinay Sajip31e928e2010-03-22 13:02:28 +0000175- Issue #8201: logging: Handle situation of non-ASCII and Unicode

Georg Brandlba83f822010-03-14 09:50:54 +0000207 for ``TimedRotatingFileHandler`` by using the modification time of an
208 existing log file to compute the next rollover time. If the log file does
209 not exist, the current time is used as the basis for the computation.
Vinay Sajip9098ee42010-03-12 06:01:21 +0000210

Georg Brandlba83f822010-03-14 09:50:54 +0000219- Issue #7143: email: ``get_payload()`` used to strip any trailing newline from
220 a base64 transfer-encoded payload *after* decoding it; it no longer does.
221 This is a behavior change, so email's minor version number is now bumped, to
222 version 4.0.2, for the 2.7 release.
R. David Murray4617e502010-03-08 02:04:06 +0000223

Mark Dickinson4846a8e2010-04-03 14:05:10 +0000248- Issue #8300: When passing a non-integer argument to struct.pack with any
249 integer format code, struct.pack first attempts to convert the non-integer
250 using its __index__ method. If that method is non-existent or raises
251 TypeError it goes on to try the __int__ method, as described below.
252
Georg Brandlba83f822010-03-14 09:50:54 +0000253- Issue #1530559: When passing a non-integer argument to struct.pack with *any*
254 integer format code (one of 'bBhHiIlLqQ'), struct.pack attempts to use the
255 argument's __int__ method to convert to an integer before packing. It also
256 produces a DeprecationWarning in this case. (In Python 2.6, the behaviour
257 was inconsistent: __int__ was used for some integer codes but not for others,
258 and the set of integer codes for which it was used differed between native
259 packing and standard packing.)

558 position to the given argument, which goes against the tradition of

655Core and Builtins
656-----------------
657
Georg Brandlba83f822010-03-14 09:50:54 +0000658- The ``__complex__()`` method is now looked up on the class of instances to
659 make it consistent with other special methods.

Antoine Pitrou5b7139a2010-01-02 21:12:58 +0000661- Issue #7462: Implement the stringlib fast search algorithm for the `rfind`,
662 `rindex`, `rsplit` and `rpartition` methods. Patch by Florent Xicluna.
663
Mark Dickinson1b34d252010-01-01 17:27:30 +0000664- Issue #5080: A number of functions and methods previously produced a
Georg Brandlba83f822010-03-14 09:50:54 +0000665 DeprecationWarning when passed a float argument where an integer was expected.
666 These functions and methods now raise TypeError instead. The majority of the
667 effects of this change are in the extension modules, but some core functions
668 and methods are affected: notably the 'chr', 'range' and 'xrange' builtins,
669 and many unicode/str methods.

681
Georg Brandlba83f822010-03-14 09:50:54 +0000682- Issue #1811: Improve accuracy and cross-platform consistency for true division
683 of integers: the result of a/b is now correctly rounded for ints a and b (at
684 least on IEEE 754 platforms), and in particular does not depend on the
685 internal representation of a long.

693
Georg Brandlba83f822010-03-14 09:50:54 +0000694 These executables now work properly with the arch(1) command: ``arch -ppc
695 python`` will start a universal binary version of python in PPC mode (unlike
696 previous releases).

Georg Brandlba83f822010-03-14 09:50:54 +0000781- Issue #5080: The argument parsing functions ``PyArg_ParseTuple()``,
782 ``PyArg_ParseTupleAndKeywords()``, ``PyArg_VaParse()``,
783 ``PyArg_VaParseTupleAndKeywords()`` and ``PyArg_Parse()`` no longer accept
784 float arguments for integer format codes (other than 'L'): previously an
785 attempt to pass a float resulted in a DeprecationWarning; now it gives a
786 TypeError. For the 'L' format code (which previously had no warning) there is
787 now a DeprecationWarning.

Georg Brandlba83f822010-03-14 09:50:54 +0000834- Issue #3382: 'F' formatting for float and complex now convert the result to
835 upper case. This only affects 'inf' and 'nan', since 'f' no longer converts
836 to 'g' for large values.
Amaury Forgeot d'Arcd7288712009-12-01 21:51:04 +0000837
Georg Brandlba83f822010-03-14 09:50:54 +0000838- Remove switch from "%f" formatting to "%g" formatting for floats larger than
839 1e50 in absolute value.
Mark Dickinson9dd5e162009-11-23 20:54:09 +0000840
Georg Brandlba83f822010-03-14 09:50:54 +0000841- Remove restrictions on precision when formatting floats. E.g., "%.120g" %
842 1e-100 used to raise OverflowError, but now gives the requested 120
843 significant digits instead.
Mark Dickinson18cfada2009-11-23 18:46:41 +0000844

850 10.6.
Ronald Oussoren315cd0c2009-11-19 16:25:21 +0000851
Georg Brandlba83f822010-03-14 09:50:54 +0000852- Issue #7117: ``repr(x)`` for a float x returns a result based on the shortest
853 decimal string that's guaranteed to round back to x under correct rounding
854 (with round-half-to-even rounding mode). Previously it gave a string based on
855 rounding x to 17 decimal digits. repr(x) for a complex number behaves
856 similarly. On platforms where the correctly-rounded strtod and dtoa code is
857 not supported (see below), repr is unchanged.
Mark Dickinsonb678de82009-11-19 18:41:49 +0000858
Georg Brandlba83f822010-03-14 09:50:54 +0000859- Issue #7117: On almost all platforms: float-to-string and string-to-float
860 conversions within Python are now correctly rounded. Places these conversions
861 occur include: str for floats and complex numbers; the float and complex
862 constructors; old-style and new-style numeric formatting; serialization and
863 deserialization of floats and complex numbers using marshal, pickle and json;
864 parsing of float and imaginary literals in Python code; Decimal-to-float
865 conversion.
Mark Dickinsonb678de82009-11-19 18:41:49 +0000866
Georg Brandlba83f822010-03-14 09:50:54 +0000867 The conversions use a Python-adapted version of David Gay's well-known dtoa.c,
868 providing correctly-rounded strtod and dtoa C functions. This code is
869 supported on Windows, and on Unix-like platforms using gcc, icc or suncc as
870 the C compiler. There may be a small number of platforms on which correct
871 operation of this code cannot be guaranteed, so the code is not used: notably,
872 this applies to platforms where the C double format is not IEEE 754 binary64,
873 and to platforms on x86 hardware where the x87 FPU is set to 64-bit precision
874 and Python's configure script is unable to determine how to change the FPU
875 precision. On these platforms conversions use the platform strtod and dtoa,
876 as before.

Georg Brandlba83f822010-03-14 09:50:54 +0000878- Issue #7117: Backport round implementation from Python 3.x. ``round()`` now
879 uses the correctly-rounded string <-> float conversions described above (when
880 available), and so produces correctly rounded results that will display nicely
881 under the float repr. There are two related small changes: (1) round now
882 accepts any class with an ``__index__()`` method for its second argument (but
883 no longer accepts floats for the second argument), and (2) an excessively
884 large second integer argument (e.g., ``round(1.234, 10**100)``) no longer
885 raises an exception.

Mark Dickinsonb1d45852009-05-11 15:33:08 +00001026- Issue #5981: Fix three minor inf/nan issues in float.fromhex:
Mark Dickinsonb1d45852009-05-11 15:33:08 +00001027
Georg Brandlba83f822010-03-14 09:50:54 +00001028 (1) inf and nan strings with trailing whitespace were incorrectly rejected;
1029 (2) parsing of strings representing infinities and nans was locale aware; and
1030 (3) the interpretation of fromhex('-nan') didn't match that of float('-nan').

Georg Brandlba83f822010-03-14 09:50:54 +00001032- Issue #5920: For ``float.__format__()``, change the behavior with the empty
1033 presentation type (that is, not one of 'e', 'f', 'g', or 'n') to be like 'g'
1034 but with at least one decimal point and with a default precision
1035 of 12. Previously, the behavior the same but with a default precision of 6.
1036 This more closely matches ``str()``, and reduces surprises when adding
1037 alignment flags to the empty presentation type. This also affects the new
1038 complex.__format__ in the same way.
1039
1040- Issue #5890: In subclasses of 'property' the __doc__ attribute was shadowed by
1041 classtype's, even if it was None. property now inserts the __doc__ into the

1291 PyUnicode_DecodeUTF8() once, remember the result and output it in a second

Georg Brandlba83f822010-03-14 09:50:54 +00002465 - If x is not an int, long or float, then packing x will always result in
2466 struct.error. Previously an x with an __int__ method could be packed by
2467 'b', 'B', 'h', 'H', 'i', 'l', '*b', '*h' ,'*i', '*l', and an x with a
2468 __long__ method could be packed by 'q', 'Q', '*q', '*Q'; for x with
2469 neither __int__ nor __long__, TypeError used to be raised (with a
2470 confusing error message) for 'I', 'L', '*B', '*H', '*I', '*L', and
2471 struct.error in other cases.

2474 argument with an __int__ method can be packed, but use of this feature
2475 triggers a DeprecationWarning.

Georg Brandlba83f822010-03-14 09:50:54 +00002524 leak-chasing test runs give sensible results. The previous method of reaping
2525 threads could return successfully while some Thread objects were still
2526 referenced. This also introduces a new private function: ``thread._count()``.
Antoine Pitrou59c44f32009-10-30 17:07:08 +00002527
Georg Brandlba83f822010-03-14 09:50:54 +00002528- Issue #7151: Fixed regrtest -j so that output to stderr from a test no longer

Georg Brandlba83f822010-03-14 09:50:54 +00002545 the same behaviour as test_ttkguionly (and now also test_tk) which is to skip

Georg Brandl2bd92a52009-10-11 21:10:07 +00002646- Issue #3850: recursion tests in Tools/scripts/find_recursion_limit.py can raise
Antoine Pitrou3c9f5412008-09-13 20:30:30 +00002647 AttributeError instead of RuntimeError, depending in which C API call
2648 exactly the recursion limit is exceeded. Consequently, both exception types
2649 are caught and silenced.

2665
Martin v. Löwis9fa5a282008-09-11 06:53:30 +00002666- Issue #3642: Suppress warning in obmalloc when size_t is larger than uint.
2667
Amaury Forgeot d'Arc05e34492008-09-10 22:04:45 +00002668- Issue #3743: In a few places, PY_FORMAT_SIZE_T was incorrectly used with
2669 PyString_FromFormat or PyErr_Format to display size_t values. The macro
2670 PY_FORMAT_SIZE_T is designed to select the correct format for the OS
2671 ``printf`` function, whereas PyString_FromFormat has an independent
2672 implementation and uses "%zd" on all platforms for size_t values.
2673 This makes a difference on win64, where ``printf`` needs "%Id" to display
2674 64bit values.
2675
Benjamin Peterson97179b02008-09-09 20:55:01 +00002676- Issue #3634: _weakref.ref(Exception).__init__() gave invalid return value on
2677 error.
2678
Amaury Forgeot d'Arcd3ffb892008-09-09 07:24:30 +00002679- Issue #3777: long() applied to a float object now always return a long
2680 object; previously an int would be returned for small values. the __long__
2681 method is allowed to return either an int or a long, but the behaviour of
2682 float objects should not change to respect backward compatibility.
2683
Amaury Forgeot d'Arc3571fbf2008-09-01 19:52:00 +00002684- Issue #3751: str.rpartition would perform a left-partition when called with
2685 a unicode argument.
2686
Benjamin Peterson17f03ca2008-09-01 14:18:30 +00002687- Issue #3683: Fix compilation when --without-threads is given.
2688
Antoine Pitroud4ae97b2008-08-29 18:39:48 +00002689- Issue #3668: Fix a memory leak with the "s*" argument parser in
Vinay Sajip35e3b032008-09-01 14:33:59 +00002690 PyArg_ParseTuple and friends, which occurred when the argument for "s*"
Antoine Pitroud4ae97b2008-08-29 18:39:48 +00002691 was correctly parsed but parsing of subsequent arguments failed.
2692
Vinay Sajip35e3b032008-09-01 14:33:59 +00002693- Issue #2534: speed up isinstance() and issubclass() by 50-70%, so as to
Antoine Pitrou0668c622008-08-26 22:42:08 +00002694 match Python 2.5 speed despite the __instancecheck__ / __subclasscheck__
2695 mechanism. In the process, fix a bug where isinstance() and issubclass(),
2696 when given a tuple of classes as second argument, were looking up
2697 __instancecheck__ / __subclasscheck__ on the tuple rather than on each
2698 type object.
2699
Neal Norwitz18aa3882008-08-24 05:04:52 +00002700- Fix crashes on memory allocation failure found with failmalloc.
2701
2702- Fix memory leaks found with valgrind and update suppressions file.
2703
2704- Fix compiler warnings in opt mode which would lead to invalid memory reads.
2705
2706- Fix problem using wrong name in decimal module reported by pychecker.
2707
Christian Heimes7d4c3172008-08-22 19:47:25 +00002708- Silenced another compiler warning about a used but not defined
2709 function 'stringlib_contains_obj'.

2712 ``__delslice__``.
2713
Gregory P. Smith2bb25cc2008-09-02 05:29:51 +00002714- Issue #3678: Correctly pass LDFLAGS and LDLAST to the linker on shared
2715 library targets in the Makefile.
2716
Gregory P. Smith980b99b2008-09-07 05:15:18 +00002717- Issue #1204: The configure script now tests for additional libraries
2718 that may be required when linking against readline. This fixes issues
2719 with x86_64 builds on some platforms (a few Linux flavors and OpenBSD).

2741
Nick Coghland2e09382008-09-11 12:11:06 +00002742- Issue #3781: Clean up the API for warnings.catch_warnings() by having it
Brett Cannon672237d2008-09-09 00:49:16 +00002743 return a list or None rather than a custom object.
2744
Benjamin Peterson6ac7d7c2008-09-06 19:28:11 +00002745- Issue #1638033: Cookie.Morsel gained the httponly attribute.

2769 warnings.catch_warnings() along with some API cleanup. Expanding the tests
2770 for catch_warnings() also led to an improvement in the raising of a
2771 DeprecationWarning related to warnings.warn_explicit().
2772
Benjamin Peterson973e6c22008-09-01 23:12:58 +00002773- The deprecation warnings for the old camelCase threading API were removed.

Barry Warsaw07a4a382008-08-21 01:15:08 +00002840*Release date: 20-Aug-2008*
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00002841
2842Core and Builtins
2843-----------------
2844
Guido van Rossumf8402962008-08-20 15:01:50 +00002845- Issue #1878: Remove Py_TPFLAGS_HAVE_VERSION_TAG from
2846 Py_TPFLAGS_DEFAULT when not building the core. This means 3rd party
2847 extensions do not automatically benefit from the class attribute
2848 cache; they will have to explicitly add Py_TPFLAGS_HAVE_VERSION_TAG
2849 to their tp_flags field if they care. This is a backwards
2850 compatibility feature; in 3.0, all types will use the cache by
2851 default.
2852
Benjamin Petersonf647dc12008-08-20 01:27:30 +00002853- Keyword arguments can now follow starred arguments. (``f(a, *args,
2854 keyword=23)`` is now valid syntax.)
2855
Thomas Heller0ad5ae02008-08-19 19:25:04 +00002856- ctypes function pointers that are COM methods have a boolean True
2857 value again.
2858
Martin v. Löwisf91d46a2008-08-12 14:49:50 +00002859- Issue #3139: Make buffer-interface thread-safe wrt. PyArg_ParseTuple,
2860 by denying s# to parse objects that have a releasebuffer procedure,
2861 and introducing s*.
2862
Georg Brandl1e13ea92008-08-11 09:07:59 +00002863- Issue #3537: Fix an assertion failure when an empty but presized dict
2864 object was stored in the freelist.
2865
Mark Dickinsonb6467572008-08-04 21:30:09 +00002866- Issue #1481296: Make long(float('nan')) and int(float('nan')) raise
2867 ValueError consistently across platforms.
2868
Amaury Forgeot d'Arc39fd6722008-07-31 21:28:03 +00002869- Issue #3479: On platforms where sizeof(int) is smaller than sizeof(long)
2870 (64bit Unix, for example), unichr() would truncate its argument and return
2871 u'\x00' for unichr(2**32). Now it properly raises an OverflowError.
2872
Neal Norwitze7d8be82008-07-31 17:17:14 +00002873- Apply security patches from Apple.
2874
Amaury Forgeot d'Arc246daed2008-07-31 00:42:16 +00002875- Issue #2542: Now that issubclass() may call arbitrary code, ensure that
2876 PyErr_ExceptionMatches returns 0 when an exception occurs there.
2877
Antoine Pitrou92f82162008-07-25 22:22:08 +00002878- Issue #1819: function calls with several named parameters are now on
2879 average 35% faster (as measured by pybench).
2880
Amaury Forgeot d'Arce4921fe2008-07-21 22:00:38 +00002881- Issue #2378: An unexpected UnboundLocalError or NameError could appear when
2882 the python debugger steps into a class statement: the free variables (local
2883 variables defined in an outer scope) would be deleted from the outer scope.
2884
Gregory P. Smith0470bab2008-07-22 04:46:32 +00002885- Issue #2620: Overflow checking when allocating or reallocating memory
2886 was not always being done properly in some python types and extension
2887 modules. PyMem_MALLOC, PyMem_REALLOC, PyMem_NEW and PyMem_RESIZE have
2888 all been updated to perform better checks and places in the code that
2889 would previously leak memory on the error path when such an allocation
2890 failed have been fixed.

Hirokazu Yamamoto838c79f2008-08-20 13:14:07 +00002895- Issue #3612: Added some missing basic types in ctypes.wintypes.
2896
Benjamin Petersone977ad42008-08-20 01:42:01 +00002897- The methods ``is_in_tuple()``, ``is_vararg()``, and ``is_keywordarg()`` of
2898 symtable.Symbol have been deprecated for removal in 3.0 and the next release.
2899
Amaury Forgeot d'Arc351ffb82008-08-18 19:23:47 +00002900- Issue #2234: distutils failed for some versions of the cygwin compiler. The
2901 version reported by these tools does not necessarily follow the python
2902 version numbering scheme, so the module is less strict when parsing it.
2903
Nick Coghlanf70385a2008-08-18 12:42:46 +00002904- Issue #2235: Added Py3k warnings for types which will become unhashable
2905 under the stricter __hash__ inheritance rules in 3.0. Several types
2906 which did not meet the rules for hash invariants and were already
2907 unhashable in 3.0 have now been explicitly flagged as unhashable in
2908 2.6 as well (collections.Mapping, collections.Set, unittest.TestSuite,
2909 xml.dom.minidom.NamedNodeMap, numbers.Number, UserList.UserList)
2910
Brett Cannon88f801d2008-08-18 00:46:22 +00002911- Update __all__ for cookielib, csv, os, urllib2, and weakref to include things
2912 imported into the module but exposed as part of the module's API.
2913
Brett Cannon7b96f072008-08-18 00:41:11 +00002914- Remove an unneeded import of abc.ABCMeta from 'inspect'.
2915

Brett Cannon25c9d6a2008-08-17 22:10:11 +00002918- Remove unneeded imports of 'warnings' from shelve, filecmp, and dummy_thread.
2919
Hirokazu Yamamoto41a81eb2008-08-17 13:10:46 +00002920- Issue #3575: Incremental decoder's decode function now takes bytearray
2921 by using 's*' instead of 't#'.
2922
Mark Dickinson3e4caeb2009-02-21 20:27:01 +00002923- Issue #2222: Fixed reference leak when occurred os.rename()

Antoine Pitroude781a42008-08-09 12:43:23 +00002980 asking for a specific length. This problem only affected files opened

3024
Nick Coghlan2a0c2b12008-08-04 12:47:17 +00003025- Issue #643841: The language reference now provides more detailed

3037-----------------
3038
Georg Brandl3e483f62008-07-16 22:57:41 +00003039- Issue #3156: Fix inconsistent behavior of the bytearray type: all
3040 its methods now allow for items objects that can be converted to
3041 an integer using operator.index().
3042
Mark Dickinson64b7e502008-07-16 09:40:03 +00003043- Issue #3360: Fix incorrect parsing of '020000000000.0', which
3044 produced a ValueError instead of giving the correct float.
3045
Eric Smitha5fa5a22008-07-16 00:11:49 +00003046- Issue #3083: Add alternate (#) formatting for bin, oct, hex output
3047 for str.format(). This adds the prefix 0b, 0o, or 0x, respectively.
3048
Mark Dickinson7103aa42008-07-15 19:08:33 +00003049- Issue #3008: the float type has a new instance method 'float.hex'
3050 and a new class method 'float.fromhex' to convert floating-point
3051 numbers to and from hexadecimal strings, respectively.
3052
Nick Coghlan6d6bd442008-07-15 15:40:22 +00003053- Issue #2235: __hash__ is once again inherited by default. To allow
3054 collections.Hashable to remain meaningful in the presence of the
3055 default hash implementation (object.__hash__), it is now possible
3056 to explicit block inheritance of hash by setting __hash__=None at
3057 the Python level, or tp_hash=PyObject_HashNotImplemented at the C
3058 level.
3059
Nick Coghlanb028f502008-07-13 14:52:36 +00003060- Issue #3221: Issue a RuntimeWarning instead of raising SystemError if
3061 the parent module cannot be found while performing an absolute import.
3062 This means that an incorrectly defined __package__ attribute will
3063 now only prevent relative imports in that module rather than causing
3064 all imports from that module to fail.
3065
Nick Coghlan14ff9942008-07-08 14:21:42 +00003066- Issue #2517: Allow unicode messages in Exceptions again by correctly

3076 another thread's dictionary.
3077
Mark Dickinson1ec2fcd2008-06-20 14:53:43 +00003078- Issue #3004: Minor change to slice.indices(): the start and stop
3079 arguments are now treated identically, making the behaviour easier
3080 to describe and understand. For example, slice(None, -10,
3081 1).indices(9) now returns (0, 0, 1) instead of (0, -1, 1), and
3082 slice(None, 10, -1).indices(10) returns (9, 9, -1) instead of (9,
3083 10, -1).
3084
Georg Brandl278fc502008-07-19 12:46:12 +00003085- Issue #3219: Calling a function with repeated keyword arguments,
3086 f(a=2, a=23), would not cause a syntax error. This was a regression
3087 from 2.4 caused by the switch to the new compiler.

Amaury Forgeot d'Arc0f7cddc2008-07-06 21:34:39 +00003125- Issue #839496: SimpleHTTPServer used to open text files in text mode. This is
3126 both unnecessary (HTTP allows text content to be sent in several forms) and
Andrew M. Kuchlingcc3f2b12008-07-10 14:43:31 +00003127 wrong because the actual transmitted size could differ from the
Amaury Forgeot d'Arc0f7cddc2008-07-06 21:34:39 +00003128 content-length. The problem had been corrected in the 2.4 branch, but never

3534
Ronald Oussoren5640ce22008-06-05 12:58:24 +00003535- On MacOS X it is now possible to install the framework in 64-bit
3536 mode or even as a 4-way universal binary (that is, PPC, i386,
Georg Brandl5cc774e2008-06-11 20:28:06 +00003537 PPC64 and x86_64 support in one binary).
Ronald Oussoren5640ce22008-06-05 12:58:24 +00003538
3539 This is controlled by the configure argument ``--with-universal-archs``:
3540
3541 - ``--with-universal-archs=all``: install 4-way universal
3542
3543 - ``--with-universal-archs=32-bit``: install 2-way universal, 32-bit (the default)
3544
3545 - ``--with-universal-archs=64-bit``: install 2-way universal, 64-bit
3546
3547 This option should be used in combination with ``--enable-universalsdk=``.
3548
3549 NOTE: 64-bit and 4-way builds are only suppported on Mac OS X 10.5 (or later).

Georg Brandl3ee81df2008-05-17 18:14:43 +00003599- Issue #1631171: Re-implement the 'warnings' module in C (the
3600 original Python code has been kept as backup). This will allow for
3601 using the 'warning's machinery in such places as the parser where
3602 use of pure Python code is not possible. Both the ``showarning()``
3603 and ``formatwarning()`` gain an optional 'line' argument which is
3604 not called by default for backwards-compatibility reasons. Setting
3605 ``warnings.showwarning()`` to an implementation that lacks support
3606 for the ``line`` argument will raise a DeprecationWarning.

Georg Brandl3ee81df2008-05-17 18:14:43 +00003669- Issue #2550: The approach used by client/server code for obtaining
3670 ports to listen on in network-oriented tests has been refined in an
3671 effort to facilitate running multiple instances of the entire
3672 regression test suite in parallel without issue.
3673 test_support.bind_port() has been fixed such that it will always
3674 return a unique port -- which wasn't always the case with the
3675 previous implementation, especially if socket options had been set
3676 that affected address reuse (i.e. SO_REUSEADDR, SO_REUSEPORT). The
3677 new implementation of bind_port() will actually raise an exception
3678 if it is passed an AF_INET/SOCK_STREAM socket with either the
3679 SO_REUSEADDR or SO_REUSEPORT socket option set. Furthermore, if
3680 available, bind_port() will set the SO_EXCLUSIVEADDRUSE option on
3681 the socket it's been passed. This currently only applies to
3682 Windows. This option prevents any other sockets from binding to the
3683 host/port we've bound to, thus removing the possibility of the
3684 'non-deterministic' behaviour, as Microsoft puts it, that occurs
3685 when a second SOCK_STREAM socket binds and accepts to a host/port
3686 that's already been bound by another socket. The optional preferred
3687 port parameter to bind_port() has been removed. Under no
3688 circumstances should tests be hard coding ports!
3689
3690 test_support.find_unused_port() has also been introduced, which will
3691 pass a temporary socket object to bind_port() in order to obtain an
3692 unused port. The temporary socket object is then closed and
3693 deleted, and the port is returned. This method should only be used
3694 for obtaining an unused port in order to pass to an external program
3695 (i.e. the -accept [port] argument to openssl's s_server mode) or as
3696 a parameter to a server-oriented class that doesn't give you direct
3697 access to the underlying socket used.
3698
3699 Finally, test_support.HOST has been introduced, which should be used
3700 for the host argument of any relevant socket calls (i.e. bind and
3701 connect).
Trent Nelsone41b0062008-04-08 23:47:30 +00003702
3703 The following tests were updated to following the new conventions:
Georg Brandl3ee81df2008-05-17 18:14:43 +00003704 test_socket, test_smtplib, test_asyncore, test_ssl, test_httplib,
Trent Nelsone41b0062008-04-08 23:47:30 +00003705 test_poplib, test_ftplib, test_telnetlib, test_socketserver,
3706 test_asynchat and test_socket_ssl.
3707
Georg Brandl3ee81df2008-05-17 18:14:43 +00003708 It is now possible for multiple instances of the regression test
3709 suite to run in parallel without issue.

3976-----------------
3977
Fred Drakea8ee94b2008-03-01 02:45:07 +00003978- Issue #2051: pyc and pyo files are no longer created with permission
Barry Warsaw52973612008-03-01 02:23:38 +00003979 644. The mode is now inherited from the py file.

Vinay Sajipb7edfc42008-04-02 21:10:23 +00003985- Issue #1881: An internal parser limit has been increased. Also see
Facundo Batistafc2d0102008-02-23 12:01:13 +00003986 issue 215555 for a discussion.
3987
Eric Smitha73fbe72008-02-23 03:09:44 +00003988- Added the future_builtins module, which contains hex() and oct().
3989 These are the PEP 3127 version of these functions, designed to be
3990 compatible with the hex() and oct() builtins from Python 3.0. They
3991 differ slightly in their output formats from the existing, unchanged
3992 Python 2.6 builtins. The expected usage of the future_builtins
3993 module is:
3994 from future_builtins import hex, oct
3995
Eric Smith7ef40bf2008-02-20 23:34:22 +00003996- Issue #1600: Modifed PyOS_ascii_formatd to use at most 2 digit
3997 exponents for exponents with absolute value < 100. Follows C99
3998 standard. This is a change on Windows, which would use 3 digits.
3999 Also, added 'n' to the formats that PyOS_ascii_formatd understands,
4000 so that any alterations it does to the resulting string will be
4001 available in stringlib/formatter.h (for float.__format__).
4002
Eric Smith5a3c1352008-02-19 13:21:56 +00004003- Implemented PEP 3101, Advanced String Formatting. This adds a new
4004 builtin format(); a format() method for str and unicode; a
4005 __format__() method to object, str, unicode, int, long, float, and
4006 datetime; the class string.Formatter; and the C API
4007 PyObject_Format().
4008
Georg Brandl3ee81df2008-05-17 18:14:43 +00004009- Fixed several potential crashes, all caused by specially crafted
4010 __del__ methods exploiting objects in temporarily inconsistent
4011 state.

Vinay Sajipb7edfc42008-04-02 21:10:23 +00004013- Issue #2115: Important speedup in setting __slot__ attributes. Also
Georg Brandl3ee81df2008-05-17 18:14:43 +00004014 prevent a possible crash: an Abstract Base Class would try to access
4015 a slot on a registered virtual subclass.

4018 real or imaginary part.
Christian Heimes2f0da532008-02-15 06:57:08 +00004019
Georg Brandl3ee81df2008-05-17 18:14:43 +00004020- Clear all free lists during a gc.collect() of the highest generation
4021 in order to allow pymalloc to free more arenas. Python may give back
4022 memory to the OS earlier.
Christian Heimes3b718a72008-02-14 12:47:33 +00004023
Georg Brandl3ee81df2008-05-17 18:14:43 +00004024- Issue #2045: Fix an infinite recursion triggered when printing a
4025 subclass of collections.defaultdict, if its default_factory is set
4026 to a bound method.
Amaury Forgeot d'Arcb01aa432008-02-08 00:56:02 +00004027
Christian Heimesf75dbef2008-02-08 00:11:31 +00004028- Fixed a minor memory leak in dictobject.c. The content of the free
4029 list was not freed on interpreter shutdown.
4030
Georg Brandl21e99f42010-03-07 15:23:59 +00004031- Limit free list of method and built-in function objects to 256
Georg Brandl3ee81df2008-05-17 18:14:43 +00004032 entries each.
Christian Heimes6075a822008-02-06 12:44:34 +00004033
Georg Brandl3ee81df2008-05-17 18:14:43 +00004034- Patch #1953: Added ``sys._compact_freelists()`` and the C API
4035 functions ``PyInt_CompactFreeList`` and ``PyFloat_CompactFreeList``
Christian Heimes422051a2008-02-04 18:00:12 +00004036 to compact the internal free lists of pre-allocted ints and floats.
4037
Georg Brandl3ee81df2008-05-17 18:14:43 +00004038- Issue #1983: Fixed return type of fork(), fork1() and forkpty()
4039 calls. Python expected the return type int but the fork familie
4040 returns pi_t.
Christian Heimes951cc0f2008-01-31 23:08:23 +00004041
Georg Brandl3ee81df2008-05-17 18:14:43 +00004042- Issue #1678380: Fix a bug that identifies 0j and -0j when they
4043 appear in the same code unit.
Mark Dickinson105be772008-01-31 22:17:37 +00004044
Georg Brandl3ee81df2008-05-17 18:14:43 +00004045- Issue #2025: Add tuple.count() and tuple.index() methods to comply
4046 with the collections.Sequence API.
Raymond Hettinger5b07ebc2008-02-07 00:54:20 +00004047
Georg Brandl3ee81df2008-05-17 18:14:43 +00004048- Patch #1970 by Antoine Pitrou: Speedup unicode whitespace and
4049 linebreak detection

Georg Brandl3ee81df2008-05-17 18:14:43 +00004051- Added ``PyType_ClearCache()`` and ``sys._clear_type_cache`` to clear
4052 the internal lookup cache for ref leak tests.
Christian Heimes908caac2008-01-27 23:34:59 +00004053
Georg Brandl3ee81df2008-05-17 18:14:43 +00004054- Patch #1473257: generator objects gain a gi_code attribute. This is
4055 the same object as the func_code attribute of the function that
4056 produced the generator.
Georg Brandl0cdf9a32008-01-26 14:14:20 +00004057
Georg Brandl3ee81df2008-05-17 18:14:43 +00004058- Issue #1920: "while 0" statements were completely removed by the
4059 compiler, even in the presence of an "else" clause, which is
4060 supposed to be run when the condition is false. Now the compiler
4061 correctly emits bytecode for the "else" suite.
Amaury Forgeot d'Arc31eaafe2008-01-24 22:59:25 +00004062
Guido van Rossumeead05f2008-01-24 18:21:02 +00004063- A few crashers fixed: weakref_in_del.py (issue #1377858);
4064 loosing_dict_ref.py (issue #1303614, test67.py);
4065 borrowed_ref_[34].py (not in tracker).
4066
Vinay Sajipd7cf32e2008-01-24 12:43:33 +00004067- Issue #1069410: The "can't load dll" message box on Windows is
Christian Heimesb2302ba2008-01-23 17:15:06 +00004068 suppressed while an extension is loaded by calling SetErrorMode in
4069 dynload_win.c. The error is still reported properly.
4070
Georg Brandl3ee81df2008-05-17 18:14:43 +00004071- Issue #1915: Python compiles with --enable-unicode=no again. However
Christian Heimes082c9b02008-01-23 14:20:50 +00004072 several extension methods and modules do not work without unicode
4073 support.
4074
Georg Brandl26543b12008-01-21 18:36:51 +00004075- Issue #1882: when compiling code from a string, encoding cookies in the
4076 second line of code were not always recognized correctly.
4077
Georg Brandl14404b62008-01-19 19:27:05 +00004078- Issue #1679: "0x" was taken as a valid integer literal.
4079
Georg Brandl6caad7d2008-01-26 14:19:22 +00004080- Issue #1865: ``bytes`` as an alias for ``str`` and b"" as an alias "" were
Christian Heimes288e89a2008-01-18 18:24:07 +00004081 added.
4082
Christian Heimesc94e2b52008-01-14 04:13:37 +00004083- sys.float_info / PyFloat_GetInfo: The floating point information
4084 object was converted from a dict to a specialized structseq object.
4085
Georg Brandl3ee81df2008-05-17 18:14:43 +00004086- Patch #1816: Added sys.flags structseq. It exposes the status of
4087 most command line arguments and PYTHON* environment variables.
Christian Heimesf31b69f2008-01-14 03:42:48 +00004088
Georg Brandl3ee81df2008-05-17 18:14:43 +00004089- Objects/structseq.c: Implemented new structseq representation. The
4090 patch makes structseqs (e.g. the return value of os.stat) more
4091 readable.
Christian Heimes9c201962008-01-14 03:33:52 +00004092
Georg Brandl3ee81df2008-05-17 18:14:43 +00004093- Patch #1700288: added a type attribute cache that caches method
4094 accesses, resulting in speedups in heavily object-oriented code.
Amaury Forgeot d'Arce4c270c2008-01-14 00:29:41 +00004095
Neal Norwitz3fc15b82008-01-10 05:42:58 +00004096- Bug #1776: __import__() no longer accepts filenames on any platform.
4097 The first parameter to __import__() must be a valid module name.
Christian Heimes3403f152008-01-09 19:56:33 +00004098
Georg Brandlaed6c662008-01-07 17:25:53 +00004099- Patch #1668: renamed THREADDEBUG envvar to PYTHONTHREADDEBUG.
4100
Georg Brandl3ee81df2008-05-17 18:14:43 +00004101- Patch #602345: Add -B command line option, PYTHONDONTWRITEBYTECODE
4102 envvar and sys.dont_write_bytecode attribute. All these can be set
4103 to forbid Python to attempt to write compiled bytecode files.
Georg Brandl2da0fce2008-01-07 17:09:35 +00004104
Georg Brandl3ee81df2008-05-17 18:14:43 +00004105- Improve some exception messages when Windows fails to load an
4106 extension module. Now we get for example '%1 is not a valid Win32
4107 application' instead of 'error code 193'.
Amaury Forgeot d'Arce0b76952008-01-04 02:04:15 +00004108
Georg Brandl3ee81df2008-05-17 18:14:43 +00004109- Bug #1481296: Fixed long(float('nan')) != 0L.

4112 y) functions.
Christian Heimese2ca4242008-01-03 20:23:15 +00004113
Christian Heimes0a8143f2007-12-18 23:22:54 +00004114- Issue #1635: Platform independent creation and representation of NaN
Georg Brandl3ee81df2008-05-17 18:14:43 +00004115 and INF. float("nan"), float("inf") and float("-inf") now work on
4116 every platform with IEEE 754 semantics.
Christian Heimes0a8143f2007-12-18 23:22:54 +00004117
Georg Brandl3ee81df2008-05-17 18:14:43 +00004118- Compiler now generates simpler and faster code for dictionary
4119 literals. The oparg for BUILD_MAP now indicates an estimated
4120 dictionary size. There is a new opcode, STORE_MAP, for adding
4121 entries to the dictionary.
Raymond Hettingerfd7ed402007-12-18 21:24:09 +00004122
Georg Brandl3ee81df2008-05-17 18:14:43 +00004123- Issue #1638: %zd configure test fails on Linux.

Andrew M. Kuchling395fe442007-12-05 13:27:20 +00004131- Issue #1553: An erroneous __length_hint__ can make list() raise a
Christian Heimes7cc1c6f2007-12-05 12:52:34 +00004132 SystemError.
4133
Nick Coghlanef01d822007-12-03 12:55:17 +00004134- PEP 366: Allow explicit relative imports when executing modules
4135 inside packages with the -m switch via a new module level

Georg Brandl3ee81df2008-05-17 18:14:43 +00004150- Patch #1739468: Directories and zipfiles containing a __main__.py
4151 file can now be directly executed by passing their name to the
4152 interpreter. The directory/zipfile is automatically inserted as the
4153 first entry in sys.path.
Nick Coghlan327a39b2007-11-18 11:56:28 +00004154
Georg Brandl3ee81df2008-05-17 18:14:43 +00004155- Issue #1265: Fix a problem with sys.settrace, if the tracing
4156 function uses a generator expression when at the same time the
4157 executed code is closing a paused generator.
Amaury Forgeot d'Arc0d75f092007-11-13 21:54:28 +00004158
Raymond Hettinger1760c8a2007-11-08 02:52:43 +00004159- sets and frozensets now have an isdisjoint() method.
4160
Raymond Hettinger3f8caa32007-10-24 01:28:33 +00004161- optimize the performance of builtin.sum().
4162
Neal Norwitz44f326e2007-10-05 05:29:17 +00004163- Fix warnings found by the new version of the Coverity checker.
4164
Georg Brandl21e99f42010-03-07 15:23:59 +00004165- The enumerate() built-in function is no longer bounded to sequences
Georg Brandl3ee81df2008-05-17 18:14:43 +00004166 smaller than LONG_MAX. Formerly, it raised an OverflowError. Now,
4167 automatically shifts from ints to longs.
Raymond Hettinger8f669372007-10-03 21:18:11 +00004168
Georg Brandl3ee81df2008-05-17 18:14:43 +00004169- Issue #1686386: Tuple's tp_repr did not take into account the
4170 possibility of having a self-referential tuple, which is possible
4171 from C code. Nor did object's tp_str consider that a type's tp_str
4172 could do something that could lead to an inifinite recursion.
4173 Py_ReprEnter() and Py_EnterRecursiveCall(), respectively, fixed the
4174 issues.
Brett Cannon0b14f242007-09-30 19:45:10 +00004175
Georg Brandl3ee81df2008-05-17 18:14:43 +00004176- Issue #1164: It was possible to trigger deadlock when using the
4177 'print' statement to write to a file since the GIL was not released
4178 as needed. Now PyObject_Print() does the right thing along with
4179 various tp_print implementations of the built-in types and those in
4180 the collections module.
Brett Cannon01531592007-09-17 03:28:34 +00004181
Georg Brandl3ee81df2008-05-17 18:14:43 +00004182- Issue #1147: Exceptions were directly allowing string exceptions in
4183 their throw() method even though string exceptions no longer
4184 allowed.
Brett Cannon4c20bc42007-09-11 21:02:28 +00004185
Georg Brandl3ee81df2008-05-17 18:14:43 +00004186- Issue #1096: Prevent a segfault from getting the repr of a very
4187 deeply nested list by using the recursion counter.
Brett Cannona0c05512007-09-10 21:38:27 +00004188
Brett Cannon1e534b52007-09-07 04:18:30 +00004189- Issue #1202533: Fix infinite recursion calls triggered by calls to
Georg Brandl3ee81df2008-05-17 18:14:43 +00004190 PyObject_Call() never calling back out to Python code to trigger
4191 recursion depth updates/checks. Required the creation of a static
4192 RuntimeError instance in case normalizing an exception put the
4193 recursion check value past its limit. Fixes crashers
4194 infinite_rec_(1|2|4|5).py.
Brett Cannon1e534b52007-09-07 04:18:30 +00004195
Georg Brandl3ee81df2008-05-17 18:14:43 +00004196- Patch #1031213: Decode source line in SyntaxErrors back to its

Neal Norwitz0ac60192007-05-27 04:08:54 +00004209- Add new attribute names for function objects. All the func_* become
Georg Brandl3ee81df2008-05-17 18:14:43 +00004210 __*__ attributes. (Some already existed, e.g., __doc__ and
4211 __name__.)
Neal Norwitz0ac60192007-05-27 04:08:54 +00004212
Neal Norwitz8b2bfbc2007-05-23 06:35:32 +00004213- Add -3 option to the interpreter to warn about features that are
4214 deprecated and will be changed/removed in Python 3.0.
4215
Georg Brandl2134e752007-05-21 20:34:16 +00004216- Patch #1686487: you can now pass any mapping after '**' in function
4217 calls.
4218
Collin Winter62903052007-05-18 23:11:24 +00004219- except clauses may now be spelled either "except E, target:" or
Georg Brandl3ee81df2008-05-17 18:14:43 +00004220 "except E as target:". This is to provide forwards compatibility
4221 with Python 3.0.
Collin Winter62903052007-05-18 23:11:24 +00004222
Brett Cannon229cee22007-05-05 01:34:02 +00004223- Deprecate BaseException.message as per PEP 352.
4224
Georg Brandl3ee81df2008-05-17 18:14:43 +00004225- Issue #1303614: don't expose object's __dict__ when the dict is
Georg Brandl21e99f42010-03-07 15:23:59 +00004226 inherited from a built-in base.
Armin Rigo9790a272007-05-02 19:23:31 +00004227
Vinay Sajip8549ce32007-05-06 17:53:37 +00004228- When __slots__ are set to a unicode string, make it work the same as
Neal Norwitzcbd9ee62007-04-14 05:25:50 +00004229 setting a plain string, ie don't expand to single letter identifiers.
4230
Raymond Hettinger13936692007-04-11 18:40:58 +00004231- Request #1191699: Slices can now be pickled.
4232
Raymond Hettinger4db5fe92007-04-12 04:10:00 +00004233- Request #1193128: str.translate() now allows a None argument for
4234 translations that only remove characters without re-mapping the
4235 remaining characters.
4236
Georg Brandl5cb76c12007-03-21 09:00:39 +00004237- Patch #1682205: a TypeError while unpacking an iterable is no longer
4238 masked by a generic one with the message "unpack non-sequence".
4239
Neal Norwitzaa754b72007-03-21 06:39:48 +00004240- Remove unused file Python/fmod.c.
4241
Guido van Rossum143b5642007-03-23 04:58:42 +00004242- Bug #1683368: The object.__init__() and object.__new__() methods are
4243 now stricter in rejecting excess arguments. The only time when
4244 either allows excess arguments is when it is not overridden and the
4245 other one is. For backwards compatibility, when both are
4246 overridden, it is a deprecation warning (for now; maybe a Py3k
Guido van Rossum234b1ff2007-03-23 19:39:01 +00004247 warning later). Also, type.__init__() insists on the same signature
4248 as supported by type.__new__().
Guido van Rossum143b5642007-03-23 04:58:42 +00004249
Georg Brandl3ee81df2008-05-17 18:14:43 +00004250- Patch #1675423: PyComplex_AsCComplex() now tries to convert an
4251 object to complex using its __complex__() method before falling back
4252 to the __float__() method. Therefore, the functions in the cmath
4253 module now can operate on objects that define a __complex__()

Gregory P. Smithbde4ae42008-01-17 08:35:49 +00005226 that the SMTP.starttls() caller no longer needs to call ehlo()
5227 beforehand. SMTP.starttls() now raises an exception of the server
Georg Brandl3ee81df2008-05-17 18:14:43 +00005228 does not claim to support starttls. Adds the
5229 SMTP.ehlo_or_helo_if_needed() method. Patch contributed by Bill
5230 Fenner.

5310 complex, tuple, list, dict, set, and frozenset. Formerly, it would
5311 silently miscode subclasses of those types. Now, it raises a
5312 ValueError instead.
Raymond Hettinger12e94202007-11-07 01:13:09 +00005313

Georg Brandl3ee81df2008-05-17 18:14:43 +00005328 time so that opening a database previously created with the DB_DUP
5329 or DB_DUPSORT flag set will keep the proper behavior on subsequent
5330 opens. Specifically: dictionary assignment to a DB object will
5331 replace all values for a given key when the database allows
5332 duplicate values. DB users should use DB.put(k, v) when they want
5333 to store duplicates; not DB[k] = v.
Gregory P. Smithec10a4a2007-11-05 02:32:26 +00005334

5340 characters with ASCII value less than 32. Also, it correctly quotes
5341 dots only if they occur on a single line, as opposed to the previous
5342 behavior of quoting dots if they are the second character of any
5343 line.
Georg Brandl4aef7272007-03-13 22:49:43 +00005344
