41
Mark Hammond323b5da2011-10-17 11:05:36 +110042- Issue #7833: Extension modules built using distutils on Windows will no
43 longer include a "manifest" to prevent them failing at import time in some
44 embedded situations.
45
Benjamin Petersona7b09762011-10-15 13:43:21 -040046- Issue #13186: Fix __delitem__ on old-style instances when invoked through

Mark Dickinsondbbed042011-09-19 16:38:08 +010055- Issue #12973: Fix overflow checks that invoked undefined behaviour in
56 int.__pow__. These overflow checks were causing int.__pow__ to produce
57 incorrect results with recent versions of Clang, as a result of the
Mark Dickinsona96b0d12011-09-24 09:01:16 +010058 compiler optimizing the check away. Also fix similar overflow checks
59 in list_repeat (listobject.c) and islice_next (itertoolsmodule.c). These
60 bugs caused test failures with recent versions of Clang.
Mark Dickinsondbbed042011-09-19 16:38:08 +010061

72 cleared by the garbage collector. This fixes a segfault when an instance
73 and its type get caught in a reference cycle, and the instance's
74 deallocator calls one of the methods on the type (e.g. when subclassing
75 IOBase). Diagnosis and patch by Davide Rizzo.
76

Victor Stinner08563d92011-05-30 23:44:13 +020084 the following case: sys.stdin.read() stopped with CTRL+d (end of file),
85 raw_input() interrupted by CTRL+c.
86
Łukasz Langa7a153902011-10-18 17:16:00 +020087- Issue #10860: httplib now correctly handles an empty port after port
88 delimiter in URLs.
89

Florent Xiclunac2279652012-02-12 14:49:03 +0100116- Issue #13994: Earlier partial revert of Distutils enhancements in 2.7
Ned Deilyc47a4592012-02-11 20:40:24 +0100117 has left two versions of customize_compiler, the original in
118 distutils.sysconfig and another copy in distutils.ccompiler, with some
119 parts of distutils calling one and others using the other.
120 Complete the revert back to only having one in distutils.sysconfig as
121 is the case in 3.x.
122
Ned Deily0d0ea482012-02-10 12:59:06 +0100123- Issue #13590: On OS X 10.7 and 10.6 with Xcode 4.2, building
124 Distutils-based packages with C extension modules may fail because
125 Apple has removed gcc-4.2, the version used to build python.org
126 64-bit/32-bit Pythons. If the user does not explicitly override
127 the default C compiler by setting the CC environment variable,
128 Distutils will now attempt to compile extension modules with clang
129 if gcc-4.2 is required but not found. Also as a convenience, if
130 the user does explicitly set CC, substitute its value as the default
131 compiler in the Distutils LDSHARED configuration variable for OS X.
132 (Note, the python.org 32-bit-only Pythons use gcc-4.0 and the 10.4u
133 SDK, neither of which are available in Xcode 4. This change does not
134 attempt to override settings to support their use with Xcode 4.)
135

Senthil Kumaran607e31e2012-02-09 17:43:31 +0800138- Issue #6005: Examples in the socket library documentation use sendall, where
139 relevant, instead send method.
140
Petri Lehtinenc7fd5232011-05-09 12:24:09 +0200141- Issue #10811: Fix recursive usage of cursors. Instead of crashing,
142 raise a ProgrammingError now.
143

Ned Deily87e82bb2011-06-28 19:52:59 -0700409- Issue #9516: On Mac OS X, change Distutils to no longer globally attempt to
410 check or set the MACOSX_DEPLOYMENT_TARGET environment variable for the
411 interpreter process. This could cause failures in non-Distutils subprocesses
412 and was unreliable since tests or user programs could modify the interpreter
413 environment after Distutils set it. Instead, have Distutils set the the
414 deployment target only in the environment of each build subprocess. It is
415 still possible to globally override the default by setting
416 MACOSX_DEPLOYMENT_TARGET before launching the interpreter; its value must be
417 greater or equal to the default value, the value with which the interpreter
418 was built.

Barry Warsawc5643282011-07-19 17:06:30 -0400446- sys.setcheckinterval() now updates the current ticker count as well as
447 updating the check interval, so if the user decreases the check interval,
448 the ticker doesn't have to wind down to zero from the old starting point
449 before the new interval takes effect. And if the user increases the
450 interval, it makes sure the new limit takes effect right away rather have an
451 early task switch before recognizing the new interval.

Mark Dickinsoncb61e5d2010-09-26 10:37:12 +00001225- Issue #9869: Make long() and PyNumber_Long return something of type
1226 long for a class whose __long__ method returns a plain int. This
1227 fixes an interpreter crash when initializing an instance of a long
1228 subclass from an object whose __long__ method returns a plain int.

1233 thread-local storage key.
1234
Victor Stinnercaafd772010-09-08 10:51:01 +00001235- Issue #4947: The write() method of sys.stdout and sys.stderr uses their
1236 encoding and errors attributes instead of using utf-8 in strict mode, to get
1237 the same behaviour than the print statement.

1369 unhelpful TypeError when called on an unconnected socket. Original patch
1370 by Andrew Bennetts.

1379
Raymond Hettinger20397532010-09-12 02:11:45 +00001380- Issue #9825: removed __del__ from the definition of collections.OrderedDict.
1381 This prevents user-created self-referencing ordered dictionaries from
1382 becoming permanently uncollectable GC garbage. The downside is that
1383 removing __del__ means that the internal doubly-linked list has to wait for
1384 GC collection rather than freeing memory immediately when the refcnt drops
1385 to zero.
1386
Raymond Hettingerffd2a422010-09-10 10:47:22 +00001387- Issue #9816: random.Random.jumpahead(n) did not produce a sufficiently

1390
Antoine Pitrouc818ed42010-09-07 21:40:25 +00001391- Issue #9792: In case of connection failure, socket.create_connection()
1392 would swallow the exception and raise a new one, making it impossible
1393 to fetch the original errno, or to filter timeout errors. Now the
1394 original error is re-raised.
1395
Antoine Pitrouf4f61712010-09-07 16:34:47 +00001396- Issue #9758: When fcntl.ioctl() was called with mutable_flag set to True,
1397 and the passed buffer was exactly 1024 bytes long, the buffer wouldn't
1398 be updated back after the system call. Original patch by Brian Brazil.
1399
Antoine Pitroudca9de92010-09-04 17:52:26 +00001400- Issue #1100562: Fix deep-copying of objects derived from the list and

Daniel Stutzbach66c981b2010-08-31 20:29:39 +00001406- Issue #808164: Fixed socket.close to avoid references to globals, to

1415
R. David Murray7c4bf552010-08-25 01:45:57 +00001416- Issue #1194222: email.utils.parsedate now returns RFC2822 compliant four
1417 character years even if the message contains RFC822 two character years.

1435
Benjamin Peterson52c36052010-08-21 03:03:22 +00001436- Issue #2521: Use weakrefs on for caching in the abc module, so that classes

1438
Raymond Hettingera54b2da2010-08-17 19:03:06 +00001439- Issue #9626: the view methods for collections.OrderedDict() were returning

1445 without this marker will not be overwritten or removed.
1446
Antoine Pitroue1436d12010-08-12 15:25:51 +00001447- Issue #7467: when reading a file from a ZIP archive, its CRC is checked

1449 case in Python 2.5 and earlier).
1450
Antoine Pitroucb4f47c2010-08-11 13:40:17 +00001451- Issue #9550: a BufferedReader could issue an additional read when the

1453 when the underlying raw IO channel was e.g. a socket. Report and original
1454 patch by Jason V. Miller.
1455
Fred Drake0a1fa0e2010-08-10 13:09:54 +00001456- Issue #9551: Don't raise TypeError when setting the value to None for

Ezio Melottiab2eb0e2010-06-05 19:21:32 +00001844- Issue #8271: during the decoding of an invalid UTF-8 byte sequence, only the
1845 start byte and the continuation byte(s) are now considered invalid, instead
1846 of the number of bytes specified by the start byte.
1847 E.g.: '\xf1\x80AB'.decode('utf-8', 'replace') now returns u'\ufffdAB' and
1848 replaces with U+FFFD only the start byte ('\xf1') and the continuation byte

1860 (2**53+1 == complex(2**53) == 2**53), breaking transivity of equality.

2057 operation raises multiple signals and more than one of those signals is
2058 trapped, the specification determines the order in which the signals should be

2246 with a non-empty format string. This is an effort to future-proof user
2247 code. If a derived class does not currently implement __format__ but later
2248 adds its own __format__, it would most likely break user code that had
Antoine Pitrou01a196a2011-01-02 20:05:11 +00002249 supplied a format string. This will be changed to a DeprecationWarning in
Georg Brandlfee0f442010-05-22 21:26:21 +00002250 Python 3.3 and it will be an error in Python 3.4.

Antoine Pitrouf3fa0742010-01-31 22:26:04 +00002742- Issue #6939: Fix file I/O objects in the `io` module to keep the original
Georg Brandlba83f822010-03-14 09:50:54 +00002743 file position when calling `truncate()`. It would previously change the file
2744 position to the given argument, which goes against the tradition of
Antoine Pitrouf3fa0742010-01-31 22:26:04 +00002745 ftruncate() and other truncation APIs. Patch by Pascal Chambon.

Georg Brandlba83f822010-03-14 09:50:54 +00002747- Issue #7610: Reworked implementation of the internal ``zipfile.ZipExtFile``
2748 class used to represent files stored inside an archive. The new
2749 implementation is significantly faster and can be wrapped in a
2750 ``io.BufferedReader`` object for more speedups. It also solves an issue
2751 where interleaved calls to ``read()`` and ``readline()`` give wrong results.

Georg Brandlba83f822010-03-14 09:50:54 +00002842- The ``__complex__()`` method is now looked up on the class of instances to
2843 make it consistent with other special methods.

2847
Mark Dickinson1b34d252010-01-01 17:27:30 +00002848- Issue #5080: A number of functions and methods previously produced a
Georg Brandlba83f822010-03-14 09:50:54 +00002849 DeprecationWarning when passed a float argument where an integer was expected.
2850 These functions and methods now raise TypeError instead. The majority of the
2851 effects of this change are in the extension modules, but some core functions
2852 and methods are affected: notably the 'chr', 'range' and 'xrange' builtins,
2853 and many unicode/str methods.

2867 of integers: the result of a/b is now correctly rounded for ints a and b (at
2868 least on IEEE 754 platforms), and in particular does not depend on the
2869 internal representation of a long.

2877
Georg Brandlba83f822010-03-14 09:50:54 +00002878 These executables now work properly with the arch(1) command: ``arch -ppc

Georg Brandlba83f822010-03-14 09:50:54 +00003018- Issue #3382: 'F' formatting for float and complex now convert the result to
3019 upper case. This only affects 'inf' and 'nan', since 'f' no longer converts
3020 to 'g' for large values.
Amaury Forgeot d'Arcd7288712009-12-01 21:51:04 +00003021
Georg Brandlba83f822010-03-14 09:50:54 +00003022- Remove switch from "%f" formatting to "%g" formatting for floats larger than
3023 1e50 in absolute value.
Mark Dickinson9dd5e162009-11-23 20:54:09 +00003024
Georg Brandlba83f822010-03-14 09:50:54 +00003025- Remove restrictions on precision when formatting floats. E.g., "%.120g" %
3026 1e-100 used to raise OverflowError, but now gives the requested 120
3027 significant digits instead.

3034 10.6.
Ronald Oussoren315cd0c2009-11-19 16:25:21 +00003035
Georg Brandlba83f822010-03-14 09:50:54 +00003036- Issue #7117: ``repr(x)`` for a float x returns a result based on the shortest
3037 decimal string that's guaranteed to round back to x under correct rounding
3038 (with round-half-to-even rounding mode). Previously it gave a string based on
3039 rounding x to 17 decimal digits. repr(x) for a complex number behaves
3040 similarly. On platforms where the correctly-rounded strtod and dtoa code is
3041 not supported (see below), repr is unchanged.
Mark Dickinsonb678de82009-11-19 18:41:49 +00003042
Georg Brandlba83f822010-03-14 09:50:54 +00003043- Issue #7117: On almost all platforms: float-to-string and string-to-float
3044 conversions within Python are now correctly rounded. Places these conversions
3045 occur include: str for floats and complex numbers; the float and complex
3046 constructors; old-style and new-style numeric formatting; serialization and
3047 deserialization of floats and complex numbers using marshal, pickle and json;
3048 parsing of float and imaginary literals in Python code; Decimal-to-float
3049 conversion.
Mark Dickinsonb678de82009-11-19 18:41:49 +00003050
Georg Brandlba83f822010-03-14 09:50:54 +00003051 The conversions use a Python-adapted version of David Gay's well-known dtoa.c,
3052 providing correctly-rounded strtod and dtoa C functions. This code is
3053 supported on Windows, and on Unix-like platforms using gcc, icc or suncc as
3054 the C compiler. There may be a small number of platforms on which correct
3055 operation of this code cannot be guaranteed, so the code is not used: notably,
3056 this applies to platforms where the C double format is not IEEE 754 binary64,
3057 and to platforms on x86 hardware where the x87 FPU is set to 64-bit precision
3058 and Python's configure script is unable to determine how to change the FPU
3059 precision. On these platforms conversions use the platform strtod and dtoa,
3060 as before.
Mark Dickinsonb678de82009-11-19 18:41:49 +00003061
Georg Brandlba83f822010-03-14 09:50:54 +00003062- Issue #7117: Backport round implementation from Python 3.x. ``round()`` now
3063 uses the correctly-rounded string <-> float conversions described above (when
3064 available), and so produces correctly rounded results that will display nicely
3065 under the float repr. There are two related small changes: (1) round now
3066 accepts any class with an ``__index__()`` method for its second argument (but
3067 no longer accepts floats for the second argument), and (2) an excessively
3068 large second integer argument (e.g., ``round(1.234, 10**100)``) no longer
3069 raises an exception.

3072
Georg Brandlba83f822010-03-14 09:50:54 +00003073- Fix several issues with ``compile()``. The input can now contain Windows and

Mark Dickinsonb1d45852009-05-11 15:33:08 +00003210- Issue #5981: Fix three minor inf/nan issues in float.fromhex:
Mark Dickinsonb1d45852009-05-11 15:33:08 +00003211
Georg Brandlba83f822010-03-14 09:50:54 +00003212 (1) inf and nan strings with trailing whitespace were incorrectly rejected;
3213 (2) parsing of strings representing infinities and nans was locale aware; and
3214 (3) the interpretation of fromhex('-nan') didn't match that of float('-nan').

Georg Brandlba83f822010-03-14 09:50:54 +00003216- Issue #5920: For ``float.__format__()``, change the behavior with the empty
3217 presentation type (that is, not one of 'e', 'f', 'g', or 'n') to be like 'g'
3218 but with at least one decimal point and with a default precision
3219 of 12. Previously, the behavior the same but with a default precision of 6.
3220 This more closely matches ``str()``, and reduces surprises when adding
3221 alignment flags to the empty presentation type. This also affects the new
3222 complex.__format__ in the same way.
3223
3224- Issue #5890: In subclasses of 'property' the __doc__ attribute was shadowed by

4652 __long__ method could be packed by 'q', 'Q', '*q', '*Q'; for x with
4653 neither __int__ nor __long__, TypeError used to be raised (with a

Georg Brandlba83f822010-03-14 09:50:54 +00004708 leak-chasing test runs give sensible results. The previous method of reaping
4709 threads could return successfully while some Thread objects were still
4710 referenced. This also introduces a new private function: ``thread._count()``.
Antoine Pitrou59c44f32009-10-30 17:07:08 +00004711
Georg Brandlba83f822010-03-14 09:50:54 +00004712- Issue #7151: Fixed regrtest -j so that output to stderr from a test no longer

Georg Brandl2bd92a52009-10-11 21:10:07 +00004830- Issue #3850: recursion tests in Tools/scripts/find_recursion_limit.py can raise
Antoine Pitrou3c9f5412008-09-13 20:30:30 +00004831 AttributeError instead of RuntimeError, depending in which C API call
4832 exactly the recursion limit is exceeded. Consequently, both exception types
4833 are caught and silenced.

Martin v. Löwis9fa5a282008-09-11 06:53:30 +00004850- Issue #3642: Suppress warning in obmalloc when size_t is larger than uint.
4851
Amaury Forgeot d'Arc05e34492008-09-10 22:04:45 +00004852- Issue #3743: In a few places, PY_FORMAT_SIZE_T was incorrectly used with
4853 PyString_FromFormat or PyErr_Format to display size_t values. The macro
4854 PY_FORMAT_SIZE_T is designed to select the correct format for the OS
4855 ``printf`` function, whereas PyString_FromFormat has an independent
4856 implementation and uses "%zd" on all platforms for size_t values.
4857 This makes a difference on win64, where ``printf`` needs "%Id" to display
4858 64bit values.
4859
Benjamin Peterson97179b02008-09-09 20:55:01 +00004860- Issue #3634: _weakref.ref(Exception).__init__() gave invalid return value on
4861 error.
4862
Amaury Forgeot d'Arcd3ffb892008-09-09 07:24:30 +00004863- Issue #3777: long() applied to a float object now always return a long
4864 object; previously an int would be returned for small values. the __long__
4865 method is allowed to return either an int or a long, but the behaviour of
4866 float objects should not change to respect backward compatibility.
4867
Amaury Forgeot d'Arc3571fbf2008-09-01 19:52:00 +00004868- Issue #3751: str.rpartition would perform a left-partition when called with
4869 a unicode argument.
4870
Benjamin Peterson17f03ca2008-09-01 14:18:30 +00004871- Issue #3683: Fix compilation when --without-threads is given.
4872
Antoine Pitroud4ae97b2008-08-29 18:39:48 +00004873- Issue #3668: Fix a memory leak with the "s*" argument parser in
Vinay Sajip35e3b032008-09-01 14:33:59 +00004874 PyArg_ParseTuple and friends, which occurred when the argument for "s*"
Antoine Pitroud4ae97b2008-08-29 18:39:48 +00004875 was correctly parsed but parsing of subsequent arguments failed.
4876
Vinay Sajip35e3b032008-09-01 14:33:59 +00004877- Issue #2534: speed up isinstance() and issubclass() by 50-70%, so as to
Antoine Pitrou0668c622008-08-26 22:42:08 +00004878 match Python 2.5 speed despite the __instancecheck__ / __subclasscheck__
4879 mechanism. In the process, fix a bug where isinstance() and issubclass(),
4880 when given a tuple of classes as second argument, were looking up
4881 __instancecheck__ / __subclasscheck__ on the tuple rather than on each
4882 type object.
4883
Neal Norwitz18aa3882008-08-24 05:04:52 +00004884- Fix crashes on memory allocation failure found with failmalloc.
4885
4886- Fix memory leaks found with valgrind and update suppressions file.
4887
4888- Fix compiler warnings in opt mode which would lead to invalid memory reads.
4889
4890- Fix problem using wrong name in decimal module reported by pychecker.
4891
Christian Heimes7d4c3172008-08-22 19:47:25 +00004892- Silenced another compiler warning about a used but not defined
4893 function 'stringlib_contains_obj'.

Benjamin Peterson712ee922008-08-24 18:10:20 +00004895- Added warnings on the use of ``__getslice__``, ``__setslice__``, or
4896 ``__delslice__``.
4897
Gregory P. Smith2bb25cc2008-09-02 05:29:51 +00004898- Issue #3678: Correctly pass LDFLAGS and LDLAST to the linker on shared
4899 library targets in the Makefile.
4900
Gregory P. Smith980b99b2008-09-07 05:15:18 +00004901- Issue #1204: The configure script now tests for additional libraries
4902 that may be required when linking against readline. This fixes issues
4903 with x86_64 builds on some platforms (a few Linux flavors and OpenBSD).

4914 stack usage in the case of deeply nested objects.
4915

Brett Cannon672237d2008-09-09 00:49:16 +00004927 return a list or None rather than a custom object.
4928
Benjamin Peterson6ac7d7c2008-09-06 19:28:11 +00004929- Issue #1638033: Cookie.Morsel gained the httponly attribute.

Brett Cannon1eaf0742008-09-02 01:25:16 +00004953 warnings.catch_warnings() along with some API cleanup. Expanding the tests
4954 for catch_warnings() also led to an improvement in the raising of a
4955 DeprecationWarning related to warnings.warn_explicit().
4956
Benjamin Peterson973e6c22008-09-01 23:12:58 +00004957- The deprecation warnings for the old camelCase threading API were removed.

Amaury Forgeot d'Arc293924b2008-09-02 23:19:56 +00004980- Issue #2975: When compiling several extension modules with Visual Studio 2008
4981 from the same python interpreter, some environment variables would grow
4982 without limit.
4983
Benjamin Peterson37346b22008-08-23 20:27:43 +00004984- Issue #3643: Added a few more checks to _testcapi to prevent segfaults by

Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00005021What's New in Python 2.6 beta 3?
5022================================

Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00005025
5026Core and Builtins
5027-----------------
5028
Guido van Rossumf8402962008-08-20 15:01:50 +00005029- Issue #1878: Remove Py_TPFLAGS_HAVE_VERSION_TAG from
5030 Py_TPFLAGS_DEFAULT when not building the core. This means 3rd party
5031 extensions do not automatically benefit from the class attribute
5032 cache; they will have to explicitly add Py_TPFLAGS_HAVE_VERSION_TAG
5033 to their tp_flags field if they care. This is a backwards
5034 compatibility feature; in 3.0, all types will use the cache by
5035 default.
5036
Benjamin Petersonf647dc12008-08-20 01:27:30 +00005037- Keyword arguments can now follow starred arguments. (``f(a, *args,
5038 keyword=23)`` is now valid syntax.)
5039
Thomas Heller0ad5ae02008-08-19 19:25:04 +00005040- ctypes function pointers that are COM methods have a boolean True
5041 value again.
5042
Martin v. Löwisf91d46a2008-08-12 14:49:50 +00005043- Issue #3139: Make buffer-interface thread-safe wrt. PyArg_ParseTuple,
5044 by denying s# to parse objects that have a releasebuffer procedure,
5045 and introducing s*.
5046
Georg Brandl1e13ea92008-08-11 09:07:59 +00005047- Issue #3537: Fix an assertion failure when an empty but presized dict
5048 object was stored in the freelist.
5049
Mark Dickinsonb6467572008-08-04 21:30:09 +00005050- Issue #1481296: Make long(float('nan')) and int(float('nan')) raise
5051 ValueError consistently across platforms.
5052
Amaury Forgeot d'Arc39fd6722008-07-31 21:28:03 +00005053- Issue #3479: On platforms where sizeof(int) is smaller than sizeof(long)
5054 (64bit Unix, for example), unichr() would truncate its argument and return
5055 u'\x00' for unichr(2**32). Now it properly raises an OverflowError.
5056
Neal Norwitze7d8be82008-07-31 17:17:14 +00005057- Apply security patches from Apple.
5058
Amaury Forgeot d'Arc246daed2008-07-31 00:42:16 +00005059- Issue #2542: Now that issubclass() may call arbitrary code, ensure that
5060 PyErr_ExceptionMatches returns 0 when an exception occurs there.
5061
Antoine Pitrou92f82162008-07-25 22:22:08 +00005062- Issue #1819: function calls with several named parameters are now on
5063 average 35% faster (as measured by pybench).
5064
Amaury Forgeot d'Arce4921fe2008-07-21 22:00:38 +00005065- Issue #2378: An unexpected UnboundLocalError or NameError could appear when
5066 the python debugger steps into a class statement: the free variables (local
5067 variables defined in an outer scope) would be deleted from the outer scope.
5068
Gregory P. Smith0470bab2008-07-22 04:46:32 +00005069- Issue #2620: Overflow checking when allocating or reallocating memory
5070 was not always being done properly in some python types and extension
5071 modules. PyMem_MALLOC, PyMem_REALLOC, PyMem_NEW and PyMem_RESIZE have
5072 all been updated to perform better checks and places in the code that
5073 would previously leak memory on the error path when such an allocation
5074 failed have been fixed.

5078
Hirokazu Yamamoto838c79f2008-08-20 13:14:07 +00005079- Issue #3612: Added some missing basic types in ctypes.wintypes.
5080
Benjamin Petersone977ad42008-08-20 01:42:01 +00005081- The methods ``is_in_tuple()``, ``is_vararg()``, and ``is_keywordarg()`` of
5082 symtable.Symbol have been deprecated for removal in 3.0 and the next release.
5083
Amaury Forgeot d'Arc351ffb82008-08-18 19:23:47 +00005084- Issue #2234: distutils failed for some versions of the cygwin compiler. The
5085 version reported by these tools does not necessarily follow the python
5086 version numbering scheme, so the module is less strict when parsing it.
5087
Nick Coghlanf70385a2008-08-18 12:42:46 +00005088- Issue #2235: Added Py3k warnings for types which will become unhashable
5089 under the stricter __hash__ inheritance rules in 3.0. Several types
5090 which did not meet the rules for hash invariants and were already
5091 unhashable in 3.0 have now been explicitly flagged as unhashable in
5092 2.6 as well (collections.Mapping, collections.Set, unittest.TestSuite,
5093 xml.dom.minidom.NamedNodeMap, numbers.Number, UserList.UserList)
5094
Brett Cannon88f801d2008-08-18 00:46:22 +00005095- Update __all__ for cookielib, csv, os, urllib2, and weakref to include things
5096 imported into the module but exposed as part of the module's API.
5097
Brett Cannon7b96f072008-08-18 00:41:11 +00005098- Remove an unneeded import of abc.ABCMeta from 'inspect'.
5099
Brett Cannon46225e72008-08-18 00:36:52 +00005100- Remove unneeded imports of 'sys' and 'warnings' from 'io'.

Brett Cannon25c9d6a2008-08-17 22:10:11 +00005102- Remove unneeded imports of 'warnings' from shelve, filecmp, and dummy_thread.
5103
Hirokazu Yamamoto41a81eb2008-08-17 13:10:46 +00005104- Issue #3575: Incremental decoder's decode function now takes bytearray
5105 by using 's*' instead of 't#'.

5208
Nick Coghlan2a0c2b12008-08-04 12:47:17 +00005209- Issue #643841: The language reference now provides more detailed

5221-----------------
5222
Georg Brandl3e483f62008-07-16 22:57:41 +00005223- Issue #3156: Fix inconsistent behavior of the bytearray type: all
5224 its methods now allow for items objects that can be converted to
5225 an integer using operator.index().
5226
Mark Dickinson64b7e502008-07-16 09:40:03 +00005227- Issue #3360: Fix incorrect parsing of '020000000000.0', which
5228 produced a ValueError instead of giving the correct float.
5229
Eric Smitha5fa5a22008-07-16 00:11:49 +00005230- Issue #3083: Add alternate (#) formatting for bin, oct, hex output
5231 for str.format(). This adds the prefix 0b, 0o, or 0x, respectively.
5232
Mark Dickinson7103aa42008-07-15 19:08:33 +00005233- Issue #3008: the float type has a new instance method 'float.hex'
5234 and a new class method 'float.fromhex' to convert floating-point
5235 numbers to and from hexadecimal strings, respectively.
5236
Nick Coghlan6d6bd442008-07-15 15:40:22 +00005237- Issue #2235: __hash__ is once again inherited by default. To allow
5238 collections.Hashable to remain meaningful in the presence of the
5239 default hash implementation (object.__hash__), it is now possible
5240 to explicit block inheritance of hash by setting __hash__=None at
5241 the Python level, or tp_hash=PyObject_HashNotImplemented at the C
5242 level.
5243
Nick Coghlanb028f502008-07-13 14:52:36 +00005244- Issue #3221: Issue a RuntimeWarning instead of raising SystemError if
5245 the parent module cannot be found while performing an absolute import.
5246 This means that an incorrectly defined __package__ attribute will
5247 now only prevent relative imports in that module rather than causing
5248 all imports from that module to fail.
5249
Nick Coghlan14ff9942008-07-08 14:21:42 +00005250- Issue #2517: Allow unicode messages in Exceptions again by correctly
5251 bypassing the instance dictionary when looking up __unicode__ on
5252 new-style classes.

5260 another thread's dictionary.
5261
Mark Dickinson1ec2fcd2008-06-20 14:53:43 +00005262- Issue #3004: Minor change to slice.indices(): the start and stop
5263 arguments are now treated identically, making the behaviour easier
5264 to describe and understand. For example, slice(None, -10,
5265 1).indices(9) now returns (0, 0, 1) instead of (0, -1, 1), and
5266 slice(None, 10, -1).indices(10) returns (9, 9, -1) instead of (9,
5267 10, -1).
5268
Georg Brandl278fc502008-07-19 12:46:12 +00005269- Issue #3219: Calling a function with repeated keyword arguments,
5270 f(a=2, a=23), would not cause a syntax error. This was a regression
5271 from 2.4 caused by the switch to the new compiler.

Georg Brandl278fc502008-07-19 12:46:12 +00005273- Issue #2862: Make int and float freelist management consistent with
5274 other freelists. Changes their CompactFreeList apis into

5281 api functions without holding the GIL, which could lead to a fatal
5282 error when they failed.
5283
Martin v. Löwisaabf4042008-08-02 07:20:25 +00005284- Issue #799428: Fix Tkinter.Misc._nametowidget to unwrap Tcl command objects.

Amaury Forgeot d'Arc0f7cddc2008-07-06 21:34:39 +00005309- Issue #839496: SimpleHTTPServer used to open text files in text mode. This is
5310 both unnecessary (HTTP allows text content to be sent in several forms) and
Andrew M. Kuchlingcc3f2b12008-07-10 14:43:31 +00005311 wrong because the actual transmitted size could differ from the
Amaury Forgeot d'Arc0f7cddc2008-07-06 21:34:39 +00005312 content-length. The problem had been corrected in the 2.4 branch, but never
5313 merged into trunk.

Nick Coghlanc060b0e2008-07-02 13:09:19 +00005328- Issue #3190: Pydoc now hides the automatic module attribute __package__ (the

5672 suitable sign) if n is large and negative; previously, it raised
5673 OverflowError.

Ronald Oussoren5640ce22008-06-05 12:58:24 +00005719- On MacOS X it is now possible to install the framework in 64-bit
5720 mode or even as a 4-way universal binary (that is, PPC, i386,
Georg Brandl5cc774e2008-06-11 20:28:06 +00005721 PPC64 and x86_64 support in one binary).
Ronald Oussoren5640ce22008-06-05 12:58:24 +00005722
5723 This is controlled by the configure argument ``--with-universal-archs``:
5724
5725 - ``--with-universal-archs=all``: install 4-way universal
5726
5727 - ``--with-universal-archs=32-bit``: install 2-way universal, 32-bit (the default)
5728
5729 - ``--with-universal-archs=64-bit``: install 2-way universal, 64-bit
5730
5731 This option should be used in combination with ``--enable-universalsdk=``.
5732
5733 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 +00005783- Issue #1631171: Re-implement the 'warnings' module in C (the
5784 original Python code has been kept as backup). This will allow for
5785 using the 'warning's machinery in such places as the parser where
5786 use of pure Python code is not possible. Both the ``showarning()``
5787 and ``formatwarning()`` gain an optional 'line' argument which is
5788 not called by default for backwards-compatibility reasons. Setting
5789 ``warnings.showwarning()`` to an implementation that lacks support
5790 for the ``line`` argument will raise a DeprecationWarning.

Georg Brandl3ee81df2008-05-17 18:14:43 +00005853- Issue #2550: The approach used by client/server code for obtaining
5854 ports to listen on in network-oriented tests has been refined in an
5855 effort to facilitate running multiple instances of the entire
5856 regression test suite in parallel without issue.
5857 test_support.bind_port() has been fixed such that it will always
5858 return a unique port -- which wasn't always the case with the
5859 previous implementation, especially if socket options had been set
5860 that affected address reuse (i.e. SO_REUSEADDR, SO_REUSEPORT). The
5861 new implementation of bind_port() will actually raise an exception
5862 if it is passed an AF_INET/SOCK_STREAM socket with either the
5863 SO_REUSEADDR or SO_REUSEPORT socket option set. Furthermore, if
5864 available, bind_port() will set the SO_EXCLUSIVEADDRUSE option on
5865 the socket it's been passed. This currently only applies to
5866 Windows. This option prevents any other sockets from binding to the
5867 host/port we've bound to, thus removing the possibility of the
5868 'non-deterministic' behaviour, as Microsoft puts it, that occurs
5869 when a second SOCK_STREAM socket binds and accepts to a host/port
5870 that's already been bound by another socket. The optional preferred
5871 port parameter to bind_port() has been removed. Under no
5872 circumstances should tests be hard coding ports!
5873
5874 test_support.find_unused_port() has also been introduced, which will
5875 pass a temporary socket object to bind_port() in order to obtain an
5876 unused port. The temporary socket object is then closed and
5877 deleted, and the port is returned. This method should only be used
5878 for obtaining an unused port in order to pass to an external program
5879 (i.e. the -accept [port] argument to openssl's s_server mode) or as
5880 a parameter to a server-oriented class that doesn't give you direct
5881 access to the underlying socket used.
5882
5883 Finally, test_support.HOST has been introduced, which should be used
5884 for the host argument of any relevant socket calls (i.e. bind and
5885 connect).
Trent Nelsone41b0062008-04-08 23:47:30 +00005886
5887 The following tests were updated to following the new conventions:
Georg Brandl3ee81df2008-05-17 18:14:43 +00005888 test_socket, test_smtplib, test_asyncore, test_ssl, test_httplib,
Trent Nelsone41b0062008-04-08 23:47:30 +00005889 test_poplib, test_ftplib, test_telnetlib, test_socketserver,
5890 test_asynchat and test_socket_ssl.
5891
Georg Brandl3ee81df2008-05-17 18:14:43 +00005892 It is now possible for multiple instances of the regression test
5893 suite to run in parallel without issue.

Amaury Forgeot d'Arc9a0d3462008-03-23 09:55:29 +00005947- Issue #1477: With narrow Unicode builds, the unicode escape sequence
Georg Brandl3ee81df2008-05-17 18:14:43 +00005948 \Uxxxxxxxx did not accept values outside the Basic Multilingual
5949 Plane. This affected raw unicode literals and the
5950 'raw-unicode-escape' codec. Now UTF-16 surrogates are generated in
5951 this case, like normal unicode literals and the 'unicode-escape'
5952 codec.

Eric Smitha73fbe72008-02-23 03:09:44 +00006172- Added the future_builtins module, which contains hex() and oct().
6173 These are the PEP 3127 version of these functions, designed to be
6174 compatible with the hex() and oct() builtins from Python 3.0. They
6175 differ slightly in their output formats from the existing, unchanged
6176 Python 2.6 builtins. The expected usage of the future_builtins
6177 module is:
6178 from future_builtins import hex, oct
6179
Eric Smith7ef40bf2008-02-20 23:34:22 +00006180- Issue #1600: Modifed PyOS_ascii_formatd to use at most 2 digit
6181 exponents for exponents with absolute value < 100. Follows C99
6182 standard. This is a change on Windows, which would use 3 digits.
6183 Also, added 'n' to the formats that PyOS_ascii_formatd understands,
6184 so that any alterations it does to the resulting string will be
6185 available in stringlib/formatter.h (for float.__format__).
6186
Eric Smith5a3c1352008-02-19 13:21:56 +00006187- Implemented PEP 3101, Advanced String Formatting. This adds a new
6188 builtin format(); a format() method for str and unicode; a
6189 __format__() method to object, str, unicode, int, long, float, and
6190 datetime; the class string.Formatter; and the C API
6191 PyObject_Format().
6192
Georg Brandl3ee81df2008-05-17 18:14:43 +00006193- Fixed several potential crashes, all caused by specially crafted
6194 __del__ methods exploiting objects in temporarily inconsistent
6195 state.
Amaury Forgeot d'Arc632fad32008-02-16 20:55:24 +00006196
Vinay Sajipb7edfc42008-04-02 21:10:23 +00006197- Issue #2115: Important speedup in setting __slot__ attributes. Also
Georg Brandl3ee81df2008-05-17 18:14:43 +00006198 prevent a possible crash: an Abstract Base Class would try to access
6199 a slot on a registered virtual subclass.
Amaury Forgeot d'Arc60d6c7f2008-02-15 21:22:45 +00006200

Georg Brandl3ee81df2008-05-17 18:14:43 +00006204- Clear all free lists during a gc.collect() of the highest generation
6205 in order to allow pymalloc to free more arenas. Python may give back
6206 memory to the OS earlier.
Christian Heimes3b718a72008-02-14 12:47:33 +00006207
Georg Brandl3ee81df2008-05-17 18:14:43 +00006208- Issue #2045: Fix an infinite recursion triggered when printing a
6209 subclass of collections.defaultdict, if its default_factory is set
6210 to a bound method.
Amaury Forgeot d'Arcb01aa432008-02-08 00:56:02 +00006211
Christian Heimesf75dbef2008-02-08 00:11:31 +00006212- Fixed a minor memory leak in dictobject.c. The content of the free
6213 list was not freed on interpreter shutdown.
6214
Georg Brandl21e99f42010-03-07 15:23:59 +00006215- Limit free list of method and built-in function objects to 256
Georg Brandl3ee81df2008-05-17 18:14:43 +00006216 entries each.
Christian Heimes6075a822008-02-06 12:44:34 +00006217
Georg Brandl3ee81df2008-05-17 18:14:43 +00006218- Patch #1953: Added ``sys._compact_freelists()`` and the C API
6219 functions ``PyInt_CompactFreeList`` and ``PyFloat_CompactFreeList``
Christian Heimes422051a2008-02-04 18:00:12 +00006220 to compact the internal free lists of pre-allocted ints and floats.
6221
Georg Brandl3ee81df2008-05-17 18:14:43 +00006222- Issue #1983: Fixed return type of fork(), fork1() and forkpty()
6223 calls. Python expected the return type int but the fork familie
6224 returns pi_t.

Georg Brandl3ee81df2008-05-17 18:14:43 +00006238- Patch #1473257: generator objects gain a gi_code attribute. This is
6239 the same object as the func_code attribute of the function that
6240 produced the generator.
Georg Brandl0cdf9a32008-01-26 14:14:20 +00006241
Georg Brandl3ee81df2008-05-17 18:14:43 +00006242- Issue #1920: "while 0" statements were completely removed by the
6243 compiler, even in the presence of an "else" clause, which is
6244 supposed to be run when the condition is false. Now the compiler
6245 correctly emits bytecode for the "else" suite.
Amaury Forgeot d'Arc31eaafe2008-01-24 22:59:25 +00006246
Guido van Rossumeead05f2008-01-24 18:21:02 +00006247- A few crashers fixed: weakref_in_del.py (issue #1377858);
6248 loosing_dict_ref.py (issue #1303614, test67.py);
6249 borrowed_ref_[34].py (not in tracker).
6250
Vinay Sajipd7cf32e2008-01-24 12:43:33 +00006251- Issue #1069410: The "can't load dll" message box on Windows is
Christian Heimesb2302ba2008-01-23 17:15:06 +00006252 suppressed while an extension is loaded by calling SetErrorMode in
6253 dynload_win.c. The error is still reported properly.
6254
Georg Brandl3ee81df2008-05-17 18:14:43 +00006255- Issue #1915: Python compiles with --enable-unicode=no again. However
Christian Heimes082c9b02008-01-23 14:20:50 +00006256 several extension methods and modules do not work without unicode
6257 support.
6258
Georg Brandl26543b12008-01-21 18:36:51 +00006259- Issue #1882: when compiling code from a string, encoding cookies in the

6263
Georg Brandl6caad7d2008-01-26 14:19:22 +00006264- Issue #1865: ``bytes`` as an alias for ``str`` and b"" as an alias "" were
Christian Heimes288e89a2008-01-18 18:24:07 +00006265 added.
6266
Christian Heimesc94e2b52008-01-14 04:13:37 +00006267- sys.float_info / PyFloat_GetInfo: The floating point information
6268 object was converted from a dict to a specialized structseq object.
6269
Georg Brandl3ee81df2008-05-17 18:14:43 +00006270- Patch #1816: Added sys.flags structseq. It exposes the status of
6271 most command line arguments and PYTHON* environment variables.
Christian Heimesf31b69f2008-01-14 03:42:48 +00006272
Georg Brandl3ee81df2008-05-17 18:14:43 +00006273- Objects/structseq.c: Implemented new structseq representation. The
6274 patch makes structseqs (e.g. the return value of os.stat) more
6275 readable.
Christian Heimes9c201962008-01-14 03:33:52 +00006276
Georg Brandl3ee81df2008-05-17 18:14:43 +00006277- Patch #1700288: added a type attribute cache that caches method
6278 accesses, resulting in speedups in heavily object-oriented code.
Amaury Forgeot d'Arce4c270c2008-01-14 00:29:41 +00006279
Neal Norwitz3fc15b82008-01-10 05:42:58 +00006280- Bug #1776: __import__() no longer accepts filenames on any platform.

6286 envvar and sys.dont_write_bytecode attribute. All these can be set
6287 to forbid Python to attempt to write compiled bytecode files.
Georg Brandl2da0fce2008-01-07 17:09:35 +00006288
Georg Brandl3ee81df2008-05-17 18:14:43 +00006289- Improve some exception messages when Windows fails to load an
6290 extension module. Now we get for example '%1 is not a valid Win32
6291 application' instead of 'error code 193'.
Amaury Forgeot d'Arce0b76952008-01-04 02:04:15 +00006292

Christian Heimes0a8143f2007-12-18 23:22:54 +00006298- Issue #1635: Platform independent creation and representation of NaN
Georg Brandl3ee81df2008-05-17 18:14:43 +00006299 and INF. float("nan"), float("inf") and float("-inf") now work on
6300 every platform with IEEE 754 semantics.
Christian Heimes0a8143f2007-12-18 23:22:54 +00006301
Georg Brandl3ee81df2008-05-17 18:14:43 +00006302- Compiler now generates simpler and faster code for dictionary
6303 literals. The oparg for BUILD_MAP now indicates an estimated
6304 dictionary size. There is a new opcode, STORE_MAP, for adding
6305 entries to the dictionary.

Georg Brandl3ee81df2008-05-17 18:14:43 +00006334- Patch #1739468: Directories and zipfiles containing a __main__.py
6335 file can now be directly executed by passing their name to the
6336 interpreter. The directory/zipfile is automatically inserted as the
6337 first entry in sys.path.
Nick Coghlan327a39b2007-11-18 11:56:28 +00006338
Georg Brandl3ee81df2008-05-17 18:14:43 +00006339- Issue #1265: Fix a problem with sys.settrace, if the tracing
6340 function uses a generator expression when at the same time the
6341 executed code is closing a paused generator.
Amaury Forgeot d'Arc0d75f092007-11-13 21:54:28 +00006342
Raymond Hettinger1760c8a2007-11-08 02:52:43 +00006343- sets and frozensets now have an isdisjoint() method.
6344
Raymond Hettinger3f8caa32007-10-24 01:28:33 +00006345- optimize the performance of builtin.sum().

6348
Georg Brandl21e99f42010-03-07 15:23:59 +00006349- The enumerate() built-in function is no longer bounded to sequences
Georg Brandl3ee81df2008-05-17 18:14:43 +00006350 smaller than LONG_MAX. Formerly, it raised an OverflowError. Now,
6351 automatically shifts from ints to longs.
Raymond Hettinger8f669372007-10-03 21:18:11 +00006352
Georg Brandl3ee81df2008-05-17 18:14:43 +00006353- Issue #1686386: Tuple's tp_repr did not take into account the
6354 possibility of having a self-referential tuple, which is possible
6355 from C code. Nor did object's tp_str consider that a type's tp_str
6356 could do something that could lead to an inifinite recursion.
6357 Py_ReprEnter() and Py_EnterRecursiveCall(), respectively, fixed the
6358 issues.
Brett Cannon0b14f242007-09-30 19:45:10 +00006359
Georg Brandl3ee81df2008-05-17 18:14:43 +00006360- Issue #1164: It was possible to trigger deadlock when using the
6361 'print' statement to write to a file since the GIL was not released
6362 as needed. Now PyObject_Print() does the right thing along with
6363 various tp_print implementations of the built-in types and those in
6364 the collections module.
Brett Cannon01531592007-09-17 03:28:34 +00006365
Georg Brandl3ee81df2008-05-17 18:14:43 +00006366- Issue #1147: Exceptions were directly allowing string exceptions in
6367 their throw() method even though string exceptions no longer
6368 allowed.
Brett Cannon4c20bc42007-09-11 21:02:28 +00006369
Georg Brandl3ee81df2008-05-17 18:14:43 +00006370- Issue #1096: Prevent a segfault from getting the repr of a very

Brett Cannon1e534b52007-09-07 04:18:30 +00006373- Issue #1202533: Fix infinite recursion calls triggered by calls to
Georg Brandl3ee81df2008-05-17 18:14:43 +00006374 PyObject_Call() never calling back out to Python code to trigger
6375 recursion depth updates/checks. Required the creation of a static
6376 RuntimeError instance in case normalizing an exception put the
6377 recursion check value past its limit. Fixes crashers
6378 infinite_rec_(1|2|4|5).py.
Brett Cannon1e534b52007-09-07 04:18:30 +00006379

Neal Norwitz0ac60192007-05-27 04:08:54 +00006393- Add new attribute names for function objects. All the func_* become
Georg Brandl3ee81df2008-05-17 18:14:43 +00006394 __*__ attributes. (Some already existed, e.g., __doc__ and
6395 __name__.)

6401 calls.
6402
Collin Winter62903052007-05-18 23:11:24 +00006403- except clauses may now be spelled either "except E, target:" or
Georg Brandl3ee81df2008-05-17 18:14:43 +00006404 "except E as target:". This is to provide forwards compatibility
6405 with Python 3.0.

Georg Brandl21e99f42010-03-07 15:23:59 +00006410 inherited from a built-in base.
Armin Rigo9790a272007-05-02 19:23:31 +00006411
Vinay Sajip8549ce32007-05-06 17:53:37 +00006412- When __slots__ are set to a unicode string, make it work the same as
Neal Norwitzcbd9ee62007-04-14 05:25:50 +00006413 setting a plain string, ie don't expand to single letter identifiers.
6414
Raymond Hettinger13936692007-04-11 18:40:58 +00006415- Request #1191699: Slices can now be pickled.
6416
Raymond Hettinger4db5fe92007-04-12 04:10:00 +00006417- Request #1193128: str.translate() now allows a None argument for
6418 translations that only remove characters without re-mapping the
6419 remaining characters.
6420
Georg Brandl5cb76c12007-03-21 09:00:39 +00006421- Patch #1682205: a TypeError while unpacking an iterable is no longer

6425
Guido van Rossum143b5642007-03-23 04:58:42 +00006426- Bug #1683368: The object.__init__() and object.__new__() methods are
6427 now stricter in rejecting excess arguments. The only time when
6428 either allows excess arguments is when it is not overridden and the
6429 other one is. For backwards compatibility, when both are
6430 overridden, it is a deprecation warning (for now; maybe a Py3k
Guido van Rossum234b1ff2007-03-23 19:39:01 +00006431 warning later). Also, type.__init__() insists on the same signature
6432 as supported by type.__new__().

Georg Brandl3ee81df2008-05-17 18:14:43 +00006434- Patch #1675423: PyComplex_AsCComplex() now tries to convert an
6435 object to complex using its __complex__() method before falling back
6436 to the __float__() method. Therefore, the functions in the cmath
6437 module now can operate on objects that define a __complex__()
6438 method.

Georg Brandl3ee81df2008-05-17 18:14:43 +00006460 its argument, if it exists. If not, it will work like before. This
6461 allows customizing the output of dir() in the presence of a
6462 __getattr__().

Georg Brandlaa2321b2007-03-07 00:40:28 +00006474- Patch #703779: unset __file__ in __main__ after running a file. This
Georg Brandl3ee81df2008-05-17 18:14:43 +00006475 makes the filenames the warning module prints much more sensible
6476 when a PYTHONSTARTUP file is used.

6491
Georg Brandl3ee81df2008-05-17 18:14:43 +00006492- When printing an unraisable error, don't print exceptions. before

Georg Brandl2c1375c2006-10-12 11:27:59 +00006544- Bug #1545497: when given an explicit base, int() did ignore NULs
6545 embedded in the string to convert.
6546
Georg Brandl846f73a2006-10-08 07:11:54 +00006547- Bug #1569998: break inside a try statement (outside a loop) is now

Georg Brandl3ee81df2008-05-17 18:14:43 +00006595 generator expressions (x for x, in ... ) works again. Fixing this
6596 problem required changing the .pyc magic number. This means that
6597 .pyc files generated before 2.5c2 will be regenerated.

Georg Brandl3ee81df2008-05-17 18:14:43 +00007400- The implementation of UnicodeError objects has been simplified
7401 (start and end attributes are now stored directly as Py_ssize_t
7402 members).
Walter Dörwald84a3efe2007-06-13 16:57:12 +00007403
Georg Brandl3ee81df2008-05-17 18:14:43 +00007404- Issue #829951: In the smtplib module, SMTP.starttls() now complies
7405 with RFC 3207 and forgets any knowledge obtained from the server not
7406 obtained from the TLS negotiation itself. Patch contributed by Bill
7407 Fenner.
Gregory P. Smith2b3ba582008-01-17 08:03:17 +00007408
Georg Brandl3ee81df2008-05-17 18:14:43 +00007409- Issue #1339: The smtplib.SMTP class has been refactored a bit such
Gregory P. Smithbde4ae42008-01-17 08:35:49 +00007410 that the SMTP.starttls() caller no longer needs to call ehlo()
7411 beforehand. SMTP.starttls() now raises an exception of the server
Georg Brandl3ee81df2008-05-17 18:14:43 +00007412 does not claim to support starttls. Adds the
7413 SMTP.ehlo_or_helo_if_needed() method. Patch contributed by Bill
7414 Fenner.

7494 complex, tuple, list, dict, set, and frozenset. Formerly, it would
7495 silently miscode subclasses of those types. Now, it raises a
7496 ValueError instead.
Raymond Hettinger12e94202007-11-07 01:13:09 +00007497

Georg Brandl3ee81df2008-05-17 18:14:43 +00007512 time so that opening a database previously created with the DB_DUP
7513 or DB_DUPSORT flag set will keep the proper behavior on subsequent
7514 opens. Specifically: dictionary assignment to a DB object will
7515 replace all values for a given key when the database allows
7516 duplicate values. DB users should use DB.put(k, v) when they want
7517 to store duplicates; not DB[k] = v.
Gregory P. Smithec10a4a2007-11-05 02:32:26 +00007518

7524 characters with ASCII value less than 32. Also, it correctly quotes
7525 dots only if they occur on a single line, as opposed to the previous
7526 behavior of quoting dots if they are the second character of any
7527 line.
Georg Brandl4aef7272007-03-13 22:49:43 +00007528
