10-----------------
11
Charles-François Natali40ab0022011-10-12 22:29:09 +020012- Issue #13156: Revert the patch for issue #10517 (reset TLS upon fork()),
13 which was only relevant for the native pthread TLS implementation.
14
Victor Stinner63c22fa2011-09-23 19:37:03 +020015- Issue #7732: Fix a crash on importing a module if a directory has the same
16 name than a Python module (e.g. "__init__.py"): don't close the file twice.
17
Mark Dickinsondbbed042011-09-19 16:38:08 +010018- Issue #12973: Fix overflow checks that invoked undefined behaviour in
19 int.__pow__. These overflow checks were causing int.__pow__ to produce
20 incorrect results with recent versions of Clang, as a result of the
Mark Dickinsona96b0d12011-09-24 09:01:16 +010021 compiler optimizing the check away. Also fix similar overflow checks
22 in list_repeat (listobject.c) and islice_next (itertoolsmodule.c). These
23 bugs caused test failures with recent versions of Clang.
Mark Dickinsondbbed042011-09-19 16:38:08 +010024

Antoine Pitrou16166452011-07-12 22:04:20 +020034- Issue #12149: Update the method cache after a type's dictionnary gets
35 cleared by the garbage collector. This fixes a segfault when an instance
36 and its type get caught in a reference cycle, and the instance's
37 deallocator calls one of the methods on the type (e.g. when subclassing
38 IOBase). Diagnosis and patch by Davide Rizzo.
39
Victor Stinnerba8b3a22011-07-08 02:07:45 +020040- Issue #12501: Adjust callable() warning: callable() is only not supported in
41 Python 3.1. callable() is again supported in Python 3.2.
42
Victor Stinner59729ff2011-07-05 11:28:19 +020043- Issue #9611, #9015: FileIO.read(), FileIO.readinto(), FileIO.write() and
44 os.write() clamp the length to INT_MAX on Windows.
45
Victor Stinnerd3c7e172011-05-30 23:49:13 +020046- Issue #1195: my_fgets() now always clears errors before calling fgets(). Fix
Victor Stinner08563d92011-05-30 23:44:13 +020047 the following case: sys.stdin.read() stopped with CTRL+d (end of file),
48 raw_input() interrupted by CTRL+c.
49
Barry Warsawc5643282011-07-19 17:06:30 -040050- dict_proxy objects now display their contents rather than just the class
51 name.

180
Ned Deily87e82bb2011-06-28 19:52:59 -0700181- Issue #9516: On Mac OS X, change Distutils to no longer globally attempt to
182 check or set the MACOSX_DEPLOYMENT_TARGET environment variable for the
183 interpreter process. This could cause failures in non-Distutils subprocesses
184 and was unreliable since tests or user programs could modify the interpreter
185 environment after Distutils set it. Instead, have Distutils set the the
186 deployment target only in the environment of each build subprocess. It is
187 still possible to globally override the default by setting
188 MACOSX_DEPLOYMENT_TARGET before launching the interpreter; its value must be
189 greater or equal to the default value, the value with which the interpreter
190 was built.

197
R David Murrayf1138bb2011-06-17 22:23:04 -0400198- Issue #11700: mailbox proxy object close methods can now be called multiple
199 times without error, and _ProxyFile now closes the wrapped file.
200
Victor Stinnerc74a6ba2011-06-17 14:06:27 +0200201- Issue #12133: AbstractHTTPHandler.do_open() of urllib.request closes the HTTP
202 connection if its getresponse() method fails with a socket error. Patch
203 written by Ezio Melotti.
204
Benjamin Peterson0eb4ac42011-06-11 15:53:11 -0500205- Issue #9284: Allow inspect.findsource() to find the source of doctest
206 functions.
207
R David Murray873c5832011-06-09 16:01:09 -0400208- Issue #10694: zipfile now ignores garbage at the end of a zipfile.
209
Brian Curtincaea7e82011-06-08 19:29:53 -0500210- Issue #11583: Speed up os.path.isdir on Windows by using GetFileAttributes

217
Barry Warsawc5643282011-07-19 17:06:30 -0400218- sys.setcheckinterval() now updates the current ticker count as well as
219 updating the check interval, so if the user decreases the check interval,
220 the ticker doesn't have to wind down to zero from the old starting point
221 before the new interval takes effect. And if the user increases the
222 interval, it makes sure the new limit takes effect right away rather have an
223 early task switch before recognizing the new interval.
Raymond Hettinger19b851d2011-06-01 18:21:42 -0700224
Victor Stinner776e69b2011-06-01 01:03:00 +0200225- Issue #12085: Fix an attribute error in subprocess.Popen destructor if the

960 encoding and errors attributes instead of using utf-8 in strict mode, to get
961 the same behaviour than the print statement.

1094 by Andrew Bennetts.
1095

1103
Raymond Hettinger20397532010-09-12 02:11:45 +00001104- Issue #9825: removed __del__ from the definition of collections.OrderedDict.
1105 This prevents user-created self-referencing ordered dictionaries from
1106 becoming permanently uncollectable GC garbage. The downside is that
1107 removing __del__ means that the internal doubly-linked list has to wait for
1108 GC collection rather than freeing memory immediately when the refcnt drops
1109 to zero.
1110
Raymond Hettingerffd2a422010-09-10 10:47:22 +00001111- Issue #9816: random.Random.jumpahead(n) did not produce a sufficiently

1114
Antoine Pitrouc818ed42010-09-07 21:40:25 +00001115- Issue #9792: In case of connection failure, socket.create_connection()
1116 would swallow the exception and raise a new one, making it impossible
1117 to fetch the original errno, or to filter timeout errors. Now the
1118 original error is re-raised.
1119
Antoine Pitrouf4f61712010-09-07 16:34:47 +00001120- Issue #9758: When fcntl.ioctl() was called with mutable_flag set to True,

1122 be updated back after the system call. Original patch by Brian Brazil.

1139
R. David Murray7c4bf552010-08-25 01:45:57 +00001140- Issue #1194222: email.utils.parsedate now returns RFC2822 compliant four
1141 character years even if the message contains RFC822 two character years.
1142
Daniel Stutzbach91287322010-08-24 21:09:30 +00001143- Issue #8750: Fixed MutableSet's methods to correctly handle

1156
Antoine Pitrou3ebaed62010-08-21 19:17:25 +00001157- Issue #9617: Signals received during a low-level write operation aren't

1159
Benjamin Peterson52c36052010-08-21 03:03:22 +00001160- Issue #2521: Use weakrefs on for caching in the abc module, so that classes

1162
Raymond Hettingera54b2da2010-08-17 19:03:06 +00001163- Issue #9626: the view methods for collections.OrderedDict() were returning

1173 case in Python 2.5 and earlier).
1174
Antoine Pitroucb4f47c2010-08-11 13:40:17 +00001175- Issue #9550: a BufferedReader could issue an additional read when the

1177 when the underlying raw IO channel was e.g. a socket. Report and original
1178 patch by Jason V. Miller.
1179
Fred Drake0a1fa0e2010-08-10 13:09:54 +00001180- Issue #9551: Don't raise TypeError when setting the value to None for

Ezio Melottiab2eb0e2010-06-05 19:21:32 +00001568- Issue #8271: during the decoding of an invalid UTF-8 byte sequence, only the
1569 start byte and the continuation byte(s) are now considered invalid, instead
1570 of the number of bytes specified by the start byte.
1571 E.g.: '\xf1\x80AB'.decode('utf-8', 'replace') now returns u'\ufffdAB' and
1572 replaces with U+FFFD only the start byte ('\xf1') and the continuation byte
1573 ('\x80') even if '\xf1' is the start byte of a 4-bytes sequence.

1584 (2**53+1 == complex(2**53) == 2**53), breaking transivity of equality.

Georg Brandlfee0f442010-05-22 21:26:21 +00001780- Issue #8567: Fix precedence of signals in Decimal module: when a Decimal
1781 operation raises multiple signals and more than one of those signals is
1782 trapped, the specification determines the order in which the signals should be
1783 handled. In many cases this order wasn't being followed, leading to the wrong

Benjamin Peterson3a1dfa22010-04-06 21:50:00 +00001956- Issue #8329: Don't return the same lists from select.select when no fds are
1957 changed.

1970 with a non-empty format string. This is an effort to future-proof user
1971 code. If a derived class does not currently implement __format__ but later
1972 adds its own __format__, it would most likely break user code that had
Antoine Pitrou01a196a2011-01-02 20:05:11 +00001973 supplied a format string. This will be changed to a DeprecationWarning in
Georg Brandlfee0f442010-05-22 21:26:21 +00001974 Python 3.3 and it will be an error in Python 3.4.

Antoine Pitroud840e512010-02-04 20:20:18 +00002459- Issue #4772: Raise a ValueError when an unknown Bluetooth protocol is

Antoine Pitrouf3fa0742010-01-31 22:26:04 +00002466- Issue #6939: Fix file I/O objects in the `io` module to keep the original
Georg Brandlba83f822010-03-14 09:50:54 +00002467 file position when calling `truncate()`. It would previously change the file
2468 position to the given argument, which goes against the tradition of
Antoine Pitrouf3fa0742010-01-31 22:26:04 +00002469 ftruncate() and other truncation APIs. Patch by Pascal Chambon.

Georg Brandlba83f822010-03-14 09:50:54 +00002471- Issue #7610: Reworked implementation of the internal ``zipfile.ZipExtFile``
2472 class used to represent files stored inside an archive. The new
2473 implementation is significantly faster and can be wrapped in a
2474 ``io.BufferedReader`` object for more speedups. It also solves an issue
2475 where interleaved calls to ``read()`` and ``readline()`` give wrong results.

2564-----------------
2565
Georg Brandlba83f822010-03-14 09:50:54 +00002566- The ``__complex__()`` method is now looked up on the class of instances to
2567 make it consistent with other special methods.

2571
Mark Dickinson1b34d252010-01-01 17:27:30 +00002572- Issue #5080: A number of functions and methods previously produced a
Georg Brandlba83f822010-03-14 09:50:54 +00002573 DeprecationWarning when passed a float argument where an integer was expected.
2574 These functions and methods now raise TypeError instead. The majority of the
2575 effects of this change are in the extension modules, but some core functions
2576 and methods are affected: notably the 'chr', 'range' and 'xrange' builtins,
2577 and many unicode/str methods.

2591 of integers: the result of a/b is now correctly rounded for ints a and b (at
2592 least on IEEE 754 platforms), and in particular does not depend on the
2593 internal representation of a long.

2601
Georg Brandlba83f822010-03-14 09:50:54 +00002602 These executables now work properly with the arch(1) command: ``arch -ppc

Georg Brandlba83f822010-03-14 09:50:54 +00002742- Issue #3382: 'F' formatting for float and complex now convert the result to
2743 upper case. This only affects 'inf' and 'nan', since 'f' no longer converts
2744 to 'g' for large values.
Amaury Forgeot d'Arcd7288712009-12-01 21:51:04 +00002745
Georg Brandlba83f822010-03-14 09:50:54 +00002746- Remove switch from "%f" formatting to "%g" formatting for floats larger than
2747 1e50 in absolute value.
Mark Dickinson9dd5e162009-11-23 20:54:09 +00002748
Georg Brandlba83f822010-03-14 09:50:54 +00002749- Remove restrictions on precision when formatting floats. E.g., "%.120g" %
2750 1e-100 used to raise OverflowError, but now gives the requested 120
2751 significant digits instead.
Mark Dickinson18cfada2009-11-23 18:46:41 +00002752

2758 10.6.
Ronald Oussoren315cd0c2009-11-19 16:25:21 +00002759
Georg Brandlba83f822010-03-14 09:50:54 +00002760- Issue #7117: ``repr(x)`` for a float x returns a result based on the shortest
2761 decimal string that's guaranteed to round back to x under correct rounding
2762 (with round-half-to-even rounding mode). Previously it gave a string based on
2763 rounding x to 17 decimal digits. repr(x) for a complex number behaves
2764 similarly. On platforms where the correctly-rounded strtod and dtoa code is
2765 not supported (see below), repr is unchanged.
Mark Dickinsonb678de82009-11-19 18:41:49 +00002766
Georg Brandlba83f822010-03-14 09:50:54 +00002767- Issue #7117: On almost all platforms: float-to-string and string-to-float
2768 conversions within Python are now correctly rounded. Places these conversions
2769 occur include: str for floats and complex numbers; the float and complex
2770 constructors; old-style and new-style numeric formatting; serialization and
2771 deserialization of floats and complex numbers using marshal, pickle and json;
2772 parsing of float and imaginary literals in Python code; Decimal-to-float
2773 conversion.
Mark Dickinsonb678de82009-11-19 18:41:49 +00002774
Georg Brandlba83f822010-03-14 09:50:54 +00002775 The conversions use a Python-adapted version of David Gay's well-known dtoa.c,
2776 providing correctly-rounded strtod and dtoa C functions. This code is
2777 supported on Windows, and on Unix-like platforms using gcc, icc or suncc as
2778 the C compiler. There may be a small number of platforms on which correct
2779 operation of this code cannot be guaranteed, so the code is not used: notably,
2780 this applies to platforms where the C double format is not IEEE 754 binary64,
2781 and to platforms on x86 hardware where the x87 FPU is set to 64-bit precision
2782 and Python's configure script is unable to determine how to change the FPU
2783 precision. On these platforms conversions use the platform strtod and dtoa,
2784 as before.
Mark Dickinsonb678de82009-11-19 18:41:49 +00002785
Georg Brandlba83f822010-03-14 09:50:54 +00002786- Issue #7117: Backport round implementation from Python 3.x. ``round()`` now
2787 uses the correctly-rounded string <-> float conversions described above (when
2788 available), and so produces correctly rounded results that will display nicely
2789 under the float repr. There are two related small changes: (1) round now
2790 accepts any class with an ``__index__()`` method for its second argument (but
2791 no longer accepts floats for the second argument), and (2) an excessively
2792 large second integer argument (e.g., ``round(1.234, 10**100)``) no longer
2793 raises an exception.

2796
Georg Brandlba83f822010-03-14 09:50:54 +00002797- Fix several issues with ``compile()``. The input can now contain Windows and

Mark Dickinsonb1d45852009-05-11 15:33:08 +00002935
Georg Brandlba83f822010-03-14 09:50:54 +00002936 (1) inf and nan strings with trailing whitespace were incorrectly rejected;
2937 (2) parsing of strings representing infinities and nans was locale aware; and
2938 (3) the interpretation of fromhex('-nan') didn't match that of float('-nan').

Georg Brandlba83f822010-03-14 09:50:54 +00002940- Issue #5920: For ``float.__format__()``, change the behavior with the empty
2941 presentation type (that is, not one of 'e', 'f', 'g', or 'n') to be like 'g'
2942 but with at least one decimal point and with a default precision
2943 of 12. Previously, the behavior the same but with a default precision of 6.
2944 This more closely matches ``str()``, and reduces surprises when adding
2945 alignment flags to the empty presentation type. This also affects the new
2946 complex.__format__ in the same way.
2947
2948- Issue #5890: In subclasses of 'property' the __doc__ attribute was shadowed by

Georg Brandlba83f822010-03-14 09:50:54 +00004432 leak-chasing test runs give sensible results. The previous method of reaping
4433 threads could return successfully while some Thread objects were still
4434 referenced. This also introduces a new private function: ``thread._count()``.
Antoine Pitrou59c44f32009-10-30 17:07:08 +00004435
Georg Brandlba83f822010-03-14 09:50:54 +00004436- Issue #7151: Fixed regrtest -j so that output to stderr from a test no longer

Georg Brandl2bd92a52009-10-11 21:10:07 +00004554- Issue #3850: recursion tests in Tools/scripts/find_recursion_limit.py can raise
Antoine Pitrou3c9f5412008-09-13 20:30:30 +00004555 AttributeError instead of RuntimeError, depending in which C API call
4556 exactly the recursion limit is exceeded. Consequently, both exception types
4557 are caught and silenced.

4573
Martin v. Löwis9fa5a282008-09-11 06:53:30 +00004574- Issue #3642: Suppress warning in obmalloc when size_t is larger than uint.
4575
Amaury Forgeot d'Arc05e34492008-09-10 22:04:45 +00004576- Issue #3743: In a few places, PY_FORMAT_SIZE_T was incorrectly used with
4577 PyString_FromFormat or PyErr_Format to display size_t values. The macro
4578 PY_FORMAT_SIZE_T is designed to select the correct format for the OS
4579 ``printf`` function, whereas PyString_FromFormat has an independent
4580 implementation and uses "%zd" on all platforms for size_t values.
4581 This makes a difference on win64, where ``printf`` needs "%Id" to display
4582 64bit values.
4583
Benjamin Peterson97179b02008-09-09 20:55:01 +00004584- Issue #3634: _weakref.ref(Exception).__init__() gave invalid return value on
4585 error.
4586
Amaury Forgeot d'Arcd3ffb892008-09-09 07:24:30 +00004587- Issue #3777: long() applied to a float object now always return a long
4588 object; previously an int would be returned for small values. the __long__
4589 method is allowed to return either an int or a long, but the behaviour of
4590 float objects should not change to respect backward compatibility.
4591
Amaury Forgeot d'Arc3571fbf2008-09-01 19:52:00 +00004592- Issue #3751: str.rpartition would perform a left-partition when called with
4593 a unicode argument.
4594
Benjamin Peterson17f03ca2008-09-01 14:18:30 +00004595- Issue #3683: Fix compilation when --without-threads is given.
4596
Antoine Pitroud4ae97b2008-08-29 18:39:48 +00004597- Issue #3668: Fix a memory leak with the "s*" argument parser in
Vinay Sajip35e3b032008-09-01 14:33:59 +00004598 PyArg_ParseTuple and friends, which occurred when the argument for "s*"
Antoine Pitroud4ae97b2008-08-29 18:39:48 +00004599 was correctly parsed but parsing of subsequent arguments failed.
4600
Vinay Sajip35e3b032008-09-01 14:33:59 +00004601- Issue #2534: speed up isinstance() and issubclass() by 50-70%, so as to
Antoine Pitrou0668c622008-08-26 22:42:08 +00004602 match Python 2.5 speed despite the __instancecheck__ / __subclasscheck__
4603 mechanism. In the process, fix a bug where isinstance() and issubclass(),
4604 when given a tuple of classes as second argument, were looking up
4605 __instancecheck__ / __subclasscheck__ on the tuple rather than on each
4606 type object.
4607
Neal Norwitz18aa3882008-08-24 05:04:52 +00004608- Fix crashes on memory allocation failure found with failmalloc.
4609
4610- Fix memory leaks found with valgrind and update suppressions file.
4611
4612- Fix compiler warnings in opt mode which would lead to invalid memory reads.
4613
4614- Fix problem using wrong name in decimal module reported by pychecker.
4615
Christian Heimes7d4c3172008-08-22 19:47:25 +00004616- Silenced another compiler warning about a used but not defined
4617 function 'stringlib_contains_obj'.
4618
Benjamin Peterson712ee922008-08-24 18:10:20 +00004619- Added warnings on the use of ``__getslice__``, ``__setslice__``, or
4620 ``__delslice__``.
4621
Gregory P. Smith2bb25cc2008-09-02 05:29:51 +00004622- Issue #3678: Correctly pass LDFLAGS and LDLAST to the linker on shared
4623 library targets in the Makefile.
4624
Gregory P. Smith980b99b2008-09-07 05:15:18 +00004625- Issue #1204: The configure script now tests for additional libraries
4626 that may be required when linking against readline. This fixes issues
4627 with x86_64 builds on some platforms (a few Linux flavors and OpenBSD).

4638 stack usage in the case of deeply nested objects.
4639

Nick Coghland2e09382008-09-11 12:11:06 +00004650- Issue #3781: Clean up the API for warnings.catch_warnings() by having it
Brett Cannon672237d2008-09-09 00:49:16 +00004651 return a list or None rather than a custom object.
4652
Benjamin Peterson6ac7d7c2008-09-06 19:28:11 +00004653- Issue #1638033: Cookie.Morsel gained the httponly attribute.

Georg Brandl222e2082010-08-01 22:27:39 +00004676- Issue #3602: Moved test.test_support.catch_warning() to
Brett Cannon1eaf0742008-09-02 01:25:16 +00004677 warnings.catch_warnings() along with some API cleanup. Expanding the tests
4678 for catch_warnings() also led to an improvement in the raising of a
4679 DeprecationWarning related to warnings.warn_explicit().
4680
Benjamin Peterson973e6c22008-09-01 23:12:58 +00004681- The deprecation warnings for the old camelCase threading API were removed.

Amaury Forgeot d'Arc293924b2008-09-02 23:19:56 +00004704- Issue #2975: When compiling several extension modules with Visual Studio 2008
4705 from the same python interpreter, some environment variables would grow
4706 without limit.
4707
Benjamin Peterson37346b22008-08-23 20:27:43 +00004708- Issue #3643: Added a few more checks to _testcapi to prevent segfaults by
4709 exploitation of poor argument checking.

4751-----------------
4752
Guido van Rossumf8402962008-08-20 15:01:50 +00004753- Issue #1878: Remove Py_TPFLAGS_HAVE_VERSION_TAG from
4754 Py_TPFLAGS_DEFAULT when not building the core. This means 3rd party
4755 extensions do not automatically benefit from the class attribute
4756 cache; they will have to explicitly add Py_TPFLAGS_HAVE_VERSION_TAG
4757 to their tp_flags field if they care. This is a backwards
4758 compatibility feature; in 3.0, all types will use the cache by
4759 default.
4760
Benjamin Petersonf647dc12008-08-20 01:27:30 +00004761- Keyword arguments can now follow starred arguments. (``f(a, *args,
4762 keyword=23)`` is now valid syntax.)
4763
Thomas Heller0ad5ae02008-08-19 19:25:04 +00004764- ctypes function pointers that are COM methods have a boolean True
4765 value again.
4766
Martin v. Löwisf91d46a2008-08-12 14:49:50 +00004767- Issue #3139: Make buffer-interface thread-safe wrt. PyArg_ParseTuple,
4768 by denying s# to parse objects that have a releasebuffer procedure,
4769 and introducing s*.
4770
Georg Brandl1e13ea92008-08-11 09:07:59 +00004771- Issue #3537: Fix an assertion failure when an empty but presized dict
4772 object was stored in the freelist.
4773
Mark Dickinsonb6467572008-08-04 21:30:09 +00004774- Issue #1481296: Make long(float('nan')) and int(float('nan')) raise
4775 ValueError consistently across platforms.
4776
Amaury Forgeot d'Arc39fd6722008-07-31 21:28:03 +00004777- Issue #3479: On platforms where sizeof(int) is smaller than sizeof(long)
4778 (64bit Unix, for example), unichr() would truncate its argument and return
4779 u'\x00' for unichr(2**32). Now it properly raises an OverflowError.
4780
Neal Norwitze7d8be82008-07-31 17:17:14 +00004781- Apply security patches from Apple.
4782
Amaury Forgeot d'Arc246daed2008-07-31 00:42:16 +00004783- Issue #2542: Now that issubclass() may call arbitrary code, ensure that
4784 PyErr_ExceptionMatches returns 0 when an exception occurs there.
4785
Antoine Pitrou92f82162008-07-25 22:22:08 +00004786- Issue #1819: function calls with several named parameters are now on
4787 average 35% faster (as measured by pybench).
4788
Amaury Forgeot d'Arce4921fe2008-07-21 22:00:38 +00004789- Issue #2378: An unexpected UnboundLocalError or NameError could appear when
4790 the python debugger steps into a class statement: the free variables (local
4791 variables defined in an outer scope) would be deleted from the outer scope.
4792
Gregory P. Smith0470bab2008-07-22 04:46:32 +00004793- Issue #2620: Overflow checking when allocating or reallocating memory
4794 was not always being done properly in some python types and extension
4795 modules. PyMem_MALLOC, PyMem_REALLOC, PyMem_NEW and PyMem_RESIZE have
4796 all been updated to perform better checks and places in the code that
4797 would previously leak memory on the error path when such an allocation
4798 failed have been fixed.

4802
Hirokazu Yamamoto838c79f2008-08-20 13:14:07 +00004803- Issue #3612: Added some missing basic types in ctypes.wintypes.
4804
Benjamin Petersone977ad42008-08-20 01:42:01 +00004805- The methods ``is_in_tuple()``, ``is_vararg()``, and ``is_keywordarg()`` of
4806 symtable.Symbol have been deprecated for removal in 3.0 and the next release.
4807
Amaury Forgeot d'Arc351ffb82008-08-18 19:23:47 +00004808- Issue #2234: distutils failed for some versions of the cygwin compiler. The
4809 version reported by these tools does not necessarily follow the python
4810 version numbering scheme, so the module is less strict when parsing it.
4811
Nick Coghlanf70385a2008-08-18 12:42:46 +00004812- Issue #2235: Added Py3k warnings for types which will become unhashable
4813 under the stricter __hash__ inheritance rules in 3.0. Several types
4814 which did not meet the rules for hash invariants and were already
4815 unhashable in 3.0 have now been explicitly flagged as unhashable in
4816 2.6 as well (collections.Mapping, collections.Set, unittest.TestSuite,
4817 xml.dom.minidom.NamedNodeMap, numbers.Number, UserList.UserList)
4818
Brett Cannon88f801d2008-08-18 00:46:22 +00004819- Update __all__ for cookielib, csv, os, urllib2, and weakref to include things
4820 imported into the module but exposed as part of the module's API.
4821
Brett Cannon7b96f072008-08-18 00:41:11 +00004822- Remove an unneeded import of abc.ABCMeta from 'inspect'.

Brett Cannon25c9d6a2008-08-17 22:10:11 +00004826- Remove unneeded imports of 'warnings' from shelve, filecmp, and dummy_thread.
4827
Hirokazu Yamamoto41a81eb2008-08-17 13:10:46 +00004828- Issue #3575: Incremental decoder's decode function now takes bytearray
4829 by using 's*' instead of 't#'.

4932
Nick Coghlan2a0c2b12008-08-04 12:47:17 +00004933- Issue #643841: The language reference now provides more detailed

4945-----------------
4946
Georg Brandl3e483f62008-07-16 22:57:41 +00004947- Issue #3156: Fix inconsistent behavior of the bytearray type: all
4948 its methods now allow for items objects that can be converted to
4949 an integer using operator.index().
4950
Mark Dickinson64b7e502008-07-16 09:40:03 +00004951- Issue #3360: Fix incorrect parsing of '020000000000.0', which
4952 produced a ValueError instead of giving the correct float.
4953
Eric Smitha5fa5a22008-07-16 00:11:49 +00004954- Issue #3083: Add alternate (#) formatting for bin, oct, hex output
4955 for str.format(). This adds the prefix 0b, 0o, or 0x, respectively.
4956
Mark Dickinson7103aa42008-07-15 19:08:33 +00004957- Issue #3008: the float type has a new instance method 'float.hex'
4958 and a new class method 'float.fromhex' to convert floating-point
4959 numbers to and from hexadecimal strings, respectively.
4960
Nick Coghlan6d6bd442008-07-15 15:40:22 +00004961- Issue #2235: __hash__ is once again inherited by default. To allow
4962 collections.Hashable to remain meaningful in the presence of the
4963 default hash implementation (object.__hash__), it is now possible
4964 to explicit block inheritance of hash by setting __hash__=None at
4965 the Python level, or tp_hash=PyObject_HashNotImplemented at the C
4966 level.
4967
Nick Coghlanb028f502008-07-13 14:52:36 +00004968- Issue #3221: Issue a RuntimeWarning instead of raising SystemError if
4969 the parent module cannot be found while performing an absolute import.
4970 This means that an incorrectly defined __package__ attribute will
4971 now only prevent relative imports in that module rather than causing
4972 all imports from that module to fail.
4973
Nick Coghlan14ff9942008-07-08 14:21:42 +00004974- Issue #2517: Allow unicode messages in Exceptions again by correctly

4984 another thread's dictionary.
4985
Mark Dickinson1ec2fcd2008-06-20 14:53:43 +00004986- Issue #3004: Minor change to slice.indices(): the start and stop
4987 arguments are now treated identically, making the behaviour easier
4988 to describe and understand. For example, slice(None, -10,
4989 1).indices(9) now returns (0, 0, 1) instead of (0, -1, 1), and
4990 slice(None, 10, -1).indices(10) returns (9, 9, -1) instead of (9,
4991 10, -1).
4992
Georg Brandl278fc502008-07-19 12:46:12 +00004993- Issue #3219: Calling a function with repeated keyword arguments,
4994 f(a=2, a=23), would not cause a syntax error. This was a regression
4995 from 2.4 caused by the switch to the new compiler.

5034 both unnecessary (HTTP allows text content to be sent in several forms) and
Andrew M. Kuchlingcc3f2b12008-07-10 14:43:31 +00005035 wrong because the actual transmitted size could differ from the
Amaury Forgeot d'Arc0f7cddc2008-07-06 21:34:39 +00005036 content-length. The problem had been corrected in the 2.4 branch, but never

5396 suitable sign) if n is large and negative; previously, it raised
5397 OverflowError.

5444 mode or even as a 4-way universal binary (that is, PPC, i386,
Georg Brandl5cc774e2008-06-11 20:28:06 +00005445 PPC64 and x86_64 support in one binary).
Ronald Oussoren5640ce22008-06-05 12:58:24 +00005446
5447 This is controlled by the configure argument ``--with-universal-archs``:
5448
5449 - ``--with-universal-archs=all``: install 4-way universal
5450
5451 - ``--with-universal-archs=32-bit``: install 2-way universal, 32-bit (the default)
5452
5453 - ``--with-universal-archs=64-bit``: install 2-way universal, 64-bit
5454
5455 This option should be used in combination with ``--enable-universalsdk=``.
5456
5457 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 +00005507- Issue #1631171: Re-implement the 'warnings' module in C (the
5508 original Python code has been kept as backup). This will allow for
5509 using the 'warning's machinery in such places as the parser where
5510 use of pure Python code is not possible. Both the ``showarning()``
5511 and ``formatwarning()`` gain an optional 'line' argument which is
5512 not called by default for backwards-compatibility reasons. Setting
5513 ``warnings.showwarning()`` to an implementation that lacks support
5514 for the ``line`` argument will raise a DeprecationWarning.

Georg Brandl3ee81df2008-05-17 18:14:43 +00005577- Issue #2550: The approach used by client/server code for obtaining
5578 ports to listen on in network-oriented tests has been refined in an
5579 effort to facilitate running multiple instances of the entire
5580 regression test suite in parallel without issue.
5581 test_support.bind_port() has been fixed such that it will always
5582 return a unique port -- which wasn't always the case with the
5583 previous implementation, especially if socket options had been set
5584 that affected address reuse (i.e. SO_REUSEADDR, SO_REUSEPORT). The
5585 new implementation of bind_port() will actually raise an exception
5586 if it is passed an AF_INET/SOCK_STREAM socket with either the
5587 SO_REUSEADDR or SO_REUSEPORT socket option set. Furthermore, if
5588 available, bind_port() will set the SO_EXCLUSIVEADDRUSE option on
5589 the socket it's been passed. This currently only applies to
5590 Windows. This option prevents any other sockets from binding to the
5591 host/port we've bound to, thus removing the possibility of the
5592 'non-deterministic' behaviour, as Microsoft puts it, that occurs
5593 when a second SOCK_STREAM socket binds and accepts to a host/port
5594 that's already been bound by another socket. The optional preferred
5595 port parameter to bind_port() has been removed. Under no
5596 circumstances should tests be hard coding ports!
5597
5598 test_support.find_unused_port() has also been introduced, which will
5599 pass a temporary socket object to bind_port() in order to obtain an
5600 unused port. The temporary socket object is then closed and
5601 deleted, and the port is returned. This method should only be used
5602 for obtaining an unused port in order to pass to an external program
5603 (i.e. the -accept [port] argument to openssl's s_server mode) or as
5604 a parameter to a server-oriented class that doesn't give you direct
5605 access to the underlying socket used.
5606
5607 Finally, test_support.HOST has been introduced, which should be used
5608 for the host argument of any relevant socket calls (i.e. bind and
5609 connect).
Trent Nelsone41b0062008-04-08 23:47:30 +00005610
5611 The following tests were updated to following the new conventions:
Georg Brandl3ee81df2008-05-17 18:14:43 +00005612 test_socket, test_smtplib, test_asyncore, test_ssl, test_httplib,
Trent Nelsone41b0062008-04-08 23:47:30 +00005613 test_poplib, test_ftplib, test_telnetlib, test_socketserver,
5614 test_asynchat and test_socket_ssl.
5615
Georg Brandl3ee81df2008-05-17 18:14:43 +00005616 It is now possible for multiple instances of the regression test
5617 suite to run in parallel without issue.

Amaury Forgeot d'Arc9a0d3462008-03-23 09:55:29 +00005671- Issue #1477: With narrow Unicode builds, the unicode escape sequence
Georg Brandl3ee81df2008-05-17 18:14:43 +00005672 \Uxxxxxxxx did not accept values outside the Basic Multilingual
5673 Plane. This affected raw unicode literals and the
5674 'raw-unicode-escape' codec. Now UTF-16 surrogates are generated in
5675 this case, like normal unicode literals and the 'unicode-escape'
5676 codec.

Eric Smitha73fbe72008-02-23 03:09:44 +00005896- Added the future_builtins module, which contains hex() and oct().
5897 These are the PEP 3127 version of these functions, designed to be
5898 compatible with the hex() and oct() builtins from Python 3.0. They
5899 differ slightly in their output formats from the existing, unchanged
5900 Python 2.6 builtins. The expected usage of the future_builtins
5901 module is:
5902 from future_builtins import hex, oct
5903
Eric Smith7ef40bf2008-02-20 23:34:22 +00005904- Issue #1600: Modifed PyOS_ascii_formatd to use at most 2 digit
5905 exponents for exponents with absolute value < 100. Follows C99
5906 standard. This is a change on Windows, which would use 3 digits.
5907 Also, added 'n' to the formats that PyOS_ascii_formatd understands,
5908 so that any alterations it does to the resulting string will be
5909 available in stringlib/formatter.h (for float.__format__).
5910
Eric Smith5a3c1352008-02-19 13:21:56 +00005911- Implemented PEP 3101, Advanced String Formatting. This adds a new
5912 builtin format(); a format() method for str and unicode; a
5913 __format__() method to object, str, unicode, int, long, float, and
5914 datetime; the class string.Formatter; and the C API
5915 PyObject_Format().
5916
Georg Brandl3ee81df2008-05-17 18:14:43 +00005917- Fixed several potential crashes, all caused by specially crafted
5918 __del__ methods exploiting objects in temporarily inconsistent
5919 state.
Amaury Forgeot d'Arc632fad32008-02-16 20:55:24 +00005920
Vinay Sajipb7edfc42008-04-02 21:10:23 +00005921- Issue #2115: Important speedup in setting __slot__ attributes. Also
Georg Brandl3ee81df2008-05-17 18:14:43 +00005922 prevent a possible crash: an Abstract Base Class would try to access
5923 a slot on a registered virtual subclass.
Amaury Forgeot d'Arc60d6c7f2008-02-15 21:22:45 +00005924

Georg Brandl3ee81df2008-05-17 18:14:43 +00005928- Clear all free lists during a gc.collect() of the highest generation
5929 in order to allow pymalloc to free more arenas. Python may give back
5930 memory to the OS earlier.
Christian Heimes3b718a72008-02-14 12:47:33 +00005931
Georg Brandl3ee81df2008-05-17 18:14:43 +00005932- Issue #2045: Fix an infinite recursion triggered when printing a
5933 subclass of collections.defaultdict, if its default_factory is set
5934 to a bound method.
Amaury Forgeot d'Arcb01aa432008-02-08 00:56:02 +00005935
Christian Heimesf75dbef2008-02-08 00:11:31 +00005936- Fixed a minor memory leak in dictobject.c. The content of the free
5937 list was not freed on interpreter shutdown.

Georg Brandl21e99f42010-03-07 15:23:59 +00005939- Limit free list of method and built-in function objects to 256
Georg Brandl3ee81df2008-05-17 18:14:43 +00005940 entries each.
Christian Heimes6075a822008-02-06 12:44:34 +00005941
Georg Brandl3ee81df2008-05-17 18:14:43 +00005942- Patch #1953: Added ``sys._compact_freelists()`` and the C API
5943 functions ``PyInt_CompactFreeList`` and ``PyFloat_CompactFreeList``
Christian Heimes422051a2008-02-04 18:00:12 +00005944 to compact the internal free lists of pre-allocted ints and floats.
5945
Georg Brandl3ee81df2008-05-17 18:14:43 +00005946- Issue #1983: Fixed return type of fork(), fork1() and forkpty()
5947 calls. Python expected the return type int but the fork familie
5948 returns pi_t.

Georg Brandl3ee81df2008-05-17 18:14:43 +00005962- Patch #1473257: generator objects gain a gi_code attribute. This is
5963 the same object as the func_code attribute of the function that
5964 produced the generator.
Georg Brandl0cdf9a32008-01-26 14:14:20 +00005965
Georg Brandl3ee81df2008-05-17 18:14:43 +00005966- Issue #1920: "while 0" statements were completely removed by the
5967 compiler, even in the presence of an "else" clause, which is
5968 supposed to be run when the condition is false. Now the compiler
5969 correctly emits bytecode for the "else" suite.
Amaury Forgeot d'Arc31eaafe2008-01-24 22:59:25 +00005970
Guido van Rossumeead05f2008-01-24 18:21:02 +00005971- A few crashers fixed: weakref_in_del.py (issue #1377858);
5972 loosing_dict_ref.py (issue #1303614, test67.py);
5973 borrowed_ref_[34].py (not in tracker).
5974
Vinay Sajipd7cf32e2008-01-24 12:43:33 +00005975- Issue #1069410: The "can't load dll" message box on Windows is
Christian Heimesb2302ba2008-01-23 17:15:06 +00005976 suppressed while an extension is loaded by calling SetErrorMode in
5977 dynload_win.c. The error is still reported properly.
5978
Georg Brandl3ee81df2008-05-17 18:14:43 +00005979- Issue #1915: Python compiles with --enable-unicode=no again. However
Christian Heimes082c9b02008-01-23 14:20:50 +00005980 several extension methods and modules do not work without unicode
5981 support.
5982
Georg Brandl26543b12008-01-21 18:36:51 +00005983- Issue #1882: when compiling code from a string, encoding cookies in the

5987
Georg Brandl6caad7d2008-01-26 14:19:22 +00005988- Issue #1865: ``bytes`` as an alias for ``str`` and b"" as an alias "" were
Christian Heimes288e89a2008-01-18 18:24:07 +00005989 added.
5990
Christian Heimesc94e2b52008-01-14 04:13:37 +00005991- sys.float_info / PyFloat_GetInfo: The floating point information
5992 object was converted from a dict to a specialized structseq object.
5993
Georg Brandl3ee81df2008-05-17 18:14:43 +00005994- Patch #1816: Added sys.flags structseq. It exposes the status of
5995 most command line arguments and PYTHON* environment variables.
Christian Heimesf31b69f2008-01-14 03:42:48 +00005996
Georg Brandl3ee81df2008-05-17 18:14:43 +00005997- Objects/structseq.c: Implemented new structseq representation. The
5998 patch makes structseqs (e.g. the return value of os.stat) more
5999 readable.
Christian Heimes9c201962008-01-14 03:33:52 +00006000
Georg Brandl3ee81df2008-05-17 18:14:43 +00006001- Patch #1700288: added a type attribute cache that caches method
6002 accesses, resulting in speedups in heavily object-oriented code.
Amaury Forgeot d'Arce4c270c2008-01-14 00:29:41 +00006003
Neal Norwitz3fc15b82008-01-10 05:42:58 +00006004- Bug #1776: __import__() no longer accepts filenames on any platform.
6005 The first parameter to __import__() must be a valid module name.
Christian Heimes3403f152008-01-09 19:56:33 +00006006
Georg Brandlaed6c662008-01-07 17:25:53 +00006007- Patch #1668: renamed THREADDEBUG envvar to PYTHONTHREADDEBUG.
6008
Georg Brandl3ee81df2008-05-17 18:14:43 +00006009- Patch #602345: Add -B command line option, PYTHONDONTWRITEBYTECODE
6010 envvar and sys.dont_write_bytecode attribute. All these can be set
6011 to forbid Python to attempt to write compiled bytecode files.
Georg Brandl2da0fce2008-01-07 17:09:35 +00006012
Georg Brandl3ee81df2008-05-17 18:14:43 +00006013- Improve some exception messages when Windows fails to load an
6014 extension module. Now we get for example '%1 is not a valid Win32
6015 application' instead of 'error code 193'.
Amaury Forgeot d'Arce0b76952008-01-04 02:04:15 +00006016

Christian Heimes0a8143f2007-12-18 23:22:54 +00006022- Issue #1635: Platform independent creation and representation of NaN
Georg Brandl3ee81df2008-05-17 18:14:43 +00006023 and INF. float("nan"), float("inf") and float("-inf") now work on
6024 every platform with IEEE 754 semantics.
Christian Heimes0a8143f2007-12-18 23:22:54 +00006025
Georg Brandl3ee81df2008-05-17 18:14:43 +00006026- Compiler now generates simpler and faster code for dictionary
6027 literals. The oparg for BUILD_MAP now indicates an estimated
6028 dictionary size. There is a new opcode, STORE_MAP, for adding
6029 entries to the dictionary.

Georg Brandl3ee81df2008-05-17 18:14:43 +00006058- Patch #1739468: Directories and zipfiles containing a __main__.py
6059 file can now be directly executed by passing their name to the
6060 interpreter. The directory/zipfile is automatically inserted as the
6061 first entry in sys.path.
Nick Coghlan327a39b2007-11-18 11:56:28 +00006062
Georg Brandl3ee81df2008-05-17 18:14:43 +00006063- Issue #1265: Fix a problem with sys.settrace, if the tracing
6064 function uses a generator expression when at the same time the
6065 executed code is closing a paused generator.
Amaury Forgeot d'Arc0d75f092007-11-13 21:54:28 +00006066
Raymond Hettinger1760c8a2007-11-08 02:52:43 +00006067- sets and frozensets now have an isdisjoint() method.
6068
Raymond Hettinger3f8caa32007-10-24 01:28:33 +00006069- optimize the performance of builtin.sum().

6072
Georg Brandl21e99f42010-03-07 15:23:59 +00006073- The enumerate() built-in function is no longer bounded to sequences
Georg Brandl3ee81df2008-05-17 18:14:43 +00006074 smaller than LONG_MAX. Formerly, it raised an OverflowError. Now,
6075 automatically shifts from ints to longs.
Raymond Hettinger8f669372007-10-03 21:18:11 +00006076
Georg Brandl3ee81df2008-05-17 18:14:43 +00006077- Issue #1686386: Tuple's tp_repr did not take into account the
6078 possibility of having a self-referential tuple, which is possible
6079 from C code. Nor did object's tp_str consider that a type's tp_str
6080 could do something that could lead to an inifinite recursion.
6081 Py_ReprEnter() and Py_EnterRecursiveCall(), respectively, fixed the
6082 issues.
Brett Cannon0b14f242007-09-30 19:45:10 +00006083
Georg Brandl3ee81df2008-05-17 18:14:43 +00006084- Issue #1164: It was possible to trigger deadlock when using the
6085 'print' statement to write to a file since the GIL was not released
6086 as needed. Now PyObject_Print() does the right thing along with
6087 various tp_print implementations of the built-in types and those in
6088 the collections module.
Brett Cannon01531592007-09-17 03:28:34 +00006089
Georg Brandl3ee81df2008-05-17 18:14:43 +00006090- Issue #1147: Exceptions were directly allowing string exceptions in
6091 their throw() method even though string exceptions no longer
6092 allowed.
Brett Cannon4c20bc42007-09-11 21:02:28 +00006093
Georg Brandl3ee81df2008-05-17 18:14:43 +00006094- Issue #1096: Prevent a segfault from getting the repr of a very

Brett Cannona0c05512007-09-10 21:38:27 +00006096
Brett Cannon1e534b52007-09-07 04:18:30 +00006097- Issue #1202533: Fix infinite recursion calls triggered by calls to
Georg Brandl3ee81df2008-05-17 18:14:43 +00006098 PyObject_Call() never calling back out to Python code to trigger
6099 recursion depth updates/checks. Required the creation of a static
6100 RuntimeError instance in case normalizing an exception put the
6101 recursion check value past its limit. Fixes crashers
6102 infinite_rec_(1|2|4|5).py.
Brett Cannon1e534b52007-09-07 04:18:30 +00006103

Neal Norwitz0ac60192007-05-27 04:08:54 +00006117- Add new attribute names for function objects. All the func_* become
Georg Brandl3ee81df2008-05-17 18:14:43 +00006118 __*__ attributes. (Some already existed, e.g., __doc__ and
6119 __name__.)

6123
Georg Brandl2134e752007-05-21 20:34:16 +00006124- Patch #1686487: you can now pass any mapping after '**' in function
6125 calls.
6126
Collin Winter62903052007-05-18 23:11:24 +00006127- except clauses may now be spelled either "except E, target:" or
Georg Brandl3ee81df2008-05-17 18:14:43 +00006128 "except E as target:". This is to provide forwards compatibility
6129 with Python 3.0.

Georg Brandl3ee81df2008-05-17 18:14:43 +00006133- Issue #1303614: don't expose object's __dict__ when the dict is
Georg Brandl21e99f42010-03-07 15:23:59 +00006134 inherited from a built-in base.
Armin Rigo9790a272007-05-02 19:23:31 +00006135
Vinay Sajip8549ce32007-05-06 17:53:37 +00006136- When __slots__ are set to a unicode string, make it work the same as
Neal Norwitzcbd9ee62007-04-14 05:25:50 +00006137 setting a plain string, ie don't expand to single letter identifiers.
6138
Raymond Hettinger13936692007-04-11 18:40:58 +00006139- Request #1191699: Slices can now be pickled.
6140
Raymond Hettinger4db5fe92007-04-12 04:10:00 +00006141- Request #1193128: str.translate() now allows a None argument for
6142 translations that only remove characters without re-mapping the
6143 remaining characters.
6144
Georg Brandl5cb76c12007-03-21 09:00:39 +00006145- Patch #1682205: a TypeError while unpacking an iterable is no longer

6149
Guido van Rossum143b5642007-03-23 04:58:42 +00006150- Bug #1683368: The object.__init__() and object.__new__() methods are
6151 now stricter in rejecting excess arguments. The only time when
6152 either allows excess arguments is when it is not overridden and the
6153 other one is. For backwards compatibility, when both are
6154 overridden, it is a deprecation warning (for now; maybe a Py3k
Guido van Rossum234b1ff2007-03-23 19:39:01 +00006155 warning later). Also, type.__init__() insists on the same signature
6156 as supported by type.__new__().

Georg Brandl3ee81df2008-05-17 18:14:43 +00006158- Patch #1675423: PyComplex_AsCComplex() now tries to convert an
6159 object to complex using its __complex__() method before falling back
6160 to the __float__() method. Therefore, the functions in the cmath
6161 module now can operate on objects that define a __complex__()
6162 method.

6182
Georg Brandl871f1bc2007-03-12 13:17:36 +00006183- The dir() function has been extended to call the __dir__() method on
Georg Brandl3ee81df2008-05-17 18:14:43 +00006184 its argument, if it exists. If not, it will work like before. This
6185 allows customizing the output of dir() in the presence of a
6186 __getattr__().

Georg Brandlaa2321b2007-03-07 00:40:28 +00006198- Patch #703779: unset __file__ in __main__ after running a file. This
Georg Brandl3ee81df2008-05-17 18:14:43 +00006199 makes the filenames the warning module prints much more sensible
6200 when a PYTHONSTARTUP file is used.

6214 sq_ass_slice instead of the sq_slice slot.
6215
Georg Brandl3ee81df2008-05-17 18:14:43 +00006216- When printing an unraisable error, don't print exceptions. before

Georg Brandl2c1375c2006-10-12 11:27:59 +00006268- Bug #1545497: when given an explicit base, int() did ignore NULs
6269 embedded in the string to convert.
6270
Georg Brandl846f73a2006-10-08 07:11:54 +00006271- Bug #1569998: break inside a try statement (outside a loop) is now

Georg Brandl3ee81df2008-05-17 18:14:43 +00006319 generator expressions (x for x, in ... ) works again. Fixing this
6320 problem required changing the .pyc magic number. This means that
6321 .pyc files generated before 2.5c2 will be regenerated.

Georg Brandl3ee81df2008-05-17 18:14:43 +00007124- The implementation of UnicodeError objects has been simplified
7125 (start and end attributes are now stored directly as Py_ssize_t
7126 members).

Georg Brandl3ee81df2008-05-17 18:14:43 +00007128- Issue #829951: In the smtplib module, SMTP.starttls() now complies
7129 with RFC 3207 and forgets any knowledge obtained from the server not
7130 obtained from the TLS negotiation itself. Patch contributed by Bill
7131 Fenner.
Gregory P. Smith2b3ba582008-01-17 08:03:17 +00007132
Georg Brandl3ee81df2008-05-17 18:14:43 +00007133- Issue #1339: The smtplib.SMTP class has been refactored a bit such
Gregory P. Smithbde4ae42008-01-17 08:35:49 +00007134 that the SMTP.starttls() caller no longer needs to call ehlo()
7135 beforehand. SMTP.starttls() now raises an exception of the server
Georg Brandl3ee81df2008-05-17 18:14:43 +00007136 does not claim to support starttls. Adds the
7137 SMTP.ehlo_or_helo_if_needed() method. Patch contributed by Bill
7138 Fenner.

7208 the behavior into line with that for list.__init__().
Raymond Hettingeradf9ffd2007-12-13 00:08:37 +00007209
Georg Brandl3ee81df2008-05-17 18:14:43 +00007210- Added wide char functions to msvcrt module: getwch, getwche, putwch

7218 complex, tuple, list, dict, set, and frozenset. Formerly, it would
7219 silently miscode subclasses of those types. Now, it raises a
7220 ValueError instead.
Raymond Hettinger12e94202007-11-07 01:13:09 +00007221

Georg Brandl3ee81df2008-05-17 18:14:43 +00007236 time so that opening a database previously created with the DB_DUP
7237 or DB_DUPSORT flag set will keep the proper behavior on subsequent
7238 opens. Specifically: dictionary assignment to a DB object will
7239 replace all values for a given key when the database allows
7240 duplicate values. DB users should use DB.put(k, v) when they want
7241 to store duplicates; not DB[k] = v.
Gregory P. Smithec10a4a2007-11-05 02:32:26 +00007242

7248 characters with ASCII value less than 32. Also, it correctly quotes
7249 dots only if they occur on a single line, as opposed to the previous
7250 behavior of quoting dots if they are the second character of any
7251 line.
Georg Brandl4aef7272007-03-13 22:49:43 +00007252
