10-----------------
11
Senthil Kumaran797b95b2011-10-21 00:32:59 +080012- Issue #12604: VTRACE macro expanded to no-op in _sre.c to avoid compiler
13 warnings. Patch by Josh Triplett and Petri Lehtinen.
14
Mark Hammond323b5da2011-10-17 11:05:36 +110015- Issue #7833: Extension modules built using distutils on Windows will no
16 longer include a "manifest" to prevent them failing at import time in some
17 embedded situations.
18
Benjamin Petersona7b09762011-10-15 13:43:21 -040019- Issue #13186: Fix __delitem__ on old-style instances when invoked through
20 PySequence_DelItem.
21
Charles-François Natali40ab0022011-10-12 22:29:09 +020022- Issue #13156: Revert the patch for issue #10517 (reset TLS upon fork()),
23 which was only relevant for the native pthread TLS implementation.
24
Victor Stinner63c22fa2011-09-23 19:37:03 +020025- Issue #7732: Fix a crash on importing a module if a directory has the same
26 name than a Python module (e.g. "__init__.py"): don't close the file twice.
27
Mark Dickinsondbbed042011-09-19 16:38:08 +010028- Issue #12973: Fix overflow checks that invoked undefined behaviour in
29 int.__pow__. These overflow checks were causing int.__pow__ to produce
30 incorrect results with recent versions of Clang, as a result of the
Mark Dickinsona96b0d12011-09-24 09:01:16 +010031 compiler optimizing the check away. Also fix similar overflow checks
32 in list_repeat (listobject.c) and islice_next (itertoolsmodule.c). These
33 bugs caused test failures with recent versions of Clang.
Mark Dickinsondbbed042011-09-19 16:38:08 +010034

Antoine Pitrou16166452011-07-12 22:04:20 +020044- Issue #12149: Update the method cache after a type's dictionnary gets
45 cleared by the garbage collector. This fixes a segfault when an instance
46 and its type get caught in a reference cycle, and the instance's
47 deallocator calls one of the methods on the type (e.g. when subclassing
48 IOBase). Diagnosis and patch by Davide Rizzo.
49
Victor Stinnerba8b3a22011-07-08 02:07:45 +020050- Issue #12501: Adjust callable() warning: callable() is only not supported in

58 raw_input() interrupted by CTRL+c.
59
Łukasz Langa7a153902011-10-18 17:16:00 +020060- Issue #10860: httplib now correctly handles an empty port after port

204
Ned Deily87e82bb2011-06-28 19:52:59 -0700205- Issue #9516: On Mac OS X, change Distutils to no longer globally attempt to
206 check or set the MACOSX_DEPLOYMENT_TARGET environment variable for the
207 interpreter process. This could cause failures in non-Distutils subprocesses
208 and was unreliable since tests or user programs could modify the interpreter
209 environment after Distutils set it. Instead, have Distutils set the the
210 deployment target only in the environment of each build subprocess. It is
211 still possible to globally override the default by setting
212 MACOSX_DEPLOYMENT_TARGET before launching the interpreter; its value must be
213 greater or equal to the default value, the value with which the interpreter
214 was built.

224
Victor Stinnerc74a6ba2011-06-17 14:06:27 +0200225- Issue #12133: AbstractHTTPHandler.do_open() of urllib.request closes the HTTP
226 connection if its getresponse() method fails with a socket error. Patch
227 written by Ezio Melotti.
228
Benjamin Peterson0eb4ac42011-06-11 15:53:11 -0500229- Issue #9284: Allow inspect.findsource() to find the source of doctest
230 functions.
231

241
Barry Warsawc5643282011-07-19 17:06:30 -0400242- sys.setcheckinterval() now updates the current ticker count as well as
243 updating the check interval, so if the user decreases the check interval,
244 the ticker doesn't have to wind down to zero from the old starting point
245 before the new interval takes effect. And if the user increases the
246 interval, it makes sure the new limit takes effect right away rather have an
247 early task switch before recognizing the new interval.

Raymond Hettinger20397532010-09-12 02:11:45 +00001131- Issue #9825: removed __del__ from the definition of collections.OrderedDict.
1132 This prevents user-created self-referencing ordered dictionaries from
1133 becoming permanently uncollectable GC garbage. The downside is that
1134 removing __del__ means that the internal doubly-linked list has to wait for
1135 GC collection rather than freeing memory immediately when the refcnt drops
1136 to zero.

1144 to fetch the original errno, or to filter timeout errors. Now the
1145 original error is re-raised.

Ezio Melottiab2eb0e2010-06-05 19:21:32 +00001595- Issue #8271: during the decoding of an invalid UTF-8 byte sequence, only the
1596 start byte and the continuation byte(s) are now considered invalid, instead
1597 of the number of bytes specified by the start byte.
1598 E.g.: '\xf1\x80AB'.decode('utf-8', 'replace') now returns u'\ufffdAB' and
1599 replaces with U+FFFD only the start byte ('\xf1') and the continuation byte
1600 ('\x80') even if '\xf1' is the start byte of a 4-bytes sequence.

Mark Dickinson4ca7c3c2010-05-30 13:18:10 +00001609- Issue #8748: Fix two issues with comparisons between complex and integer
1610 objects. (1) The comparison could incorrectly return True in some cases
1611 (2**53+1 == complex(2**53) == 2**53), breaking transivity of equality.
1612 (2) The comparison raised an OverflowError for large integers, leading
1613 to unpredictable exceptions when combining integers and complex objects
1614 in sets or dicts.

Mark Dickinson81336372010-05-30 12:12:25 +00001616- Issue #5211: Implicit coercion for the complex type is now completely

Georg Brandlfee0f442010-05-22 21:26:21 +00001996- Issue #7994: Issue a PendingDeprecationWarning if object.__format__ is called
1997 with a non-empty format string. This is an effort to future-proof user
1998 code. If a derived class does not currently implement __format__ but later
1999 adds its own __format__, it would most likely break user code that had
Antoine Pitrou01a196a2011-01-02 20:05:11 +00002000 supplied a format string. This will be changed to a DeprecationWarning in
Georg Brandlfee0f442010-05-22 21:26:21 +00002001 Python 3.3 and it will be an error in Python 3.4.

Georg Brandlba83f822010-03-14 09:50:54 +00002494 file position when calling `truncate()`. It would previously change the file
2495 position to the given argument, which goes against the tradition of
Antoine Pitrouf3fa0742010-01-31 22:26:04 +00002496 ftruncate() and other truncation APIs. Patch by Pascal Chambon.

2499 class used to represent files stored inside an archive. The new
2500 implementation is significantly faster and can be wrapped in a

2502 where interleaved calls to ``read()`` and ``readline()`` give wrong results.

2592
Georg Brandlba83f822010-03-14 09:50:54 +00002593- The ``__complex__()`` method is now looked up on the class of instances to
2594 make it consistent with other special methods.

2598
Mark Dickinson1b34d252010-01-01 17:27:30 +00002599- Issue #5080: A number of functions and methods previously produced a
Georg Brandlba83f822010-03-14 09:50:54 +00002600 DeprecationWarning when passed a float argument where an integer was expected.
2601 These functions and methods now raise TypeError instead. The majority of the
2602 effects of this change are in the extension modules, but some core functions
2603 and methods are affected: notably the 'chr', 'range' and 'xrange' builtins,
2604 and many unicode/str methods.

2618 of integers: the result of a/b is now correctly rounded for ints a and b (at
2619 least on IEEE 754 platforms), and in particular does not depend on the
2620 internal representation of a long.

2628
Georg Brandlba83f822010-03-14 09:50:54 +00002629 These executables now work properly with the arch(1) command: ``arch -ppc
2630 python`` will start a universal binary version of python in PPC mode (unlike

Georg Brandlba83f822010-03-14 09:50:54 +00002787- Issue #7117: ``repr(x)`` for a float x returns a result based on the shortest
2788 decimal string that's guaranteed to round back to x under correct rounding
2789 (with round-half-to-even rounding mode). Previously it gave a string based on
2790 rounding x to 17 decimal digits. repr(x) for a complex number behaves
2791 similarly. On platforms where the correctly-rounded strtod and dtoa code is
2792 not supported (see below), repr is unchanged.
Mark Dickinsonb678de82009-11-19 18:41:49 +00002793
Georg Brandlba83f822010-03-14 09:50:54 +00002794- Issue #7117: On almost all platforms: float-to-string and string-to-float
2795 conversions within Python are now correctly rounded. Places these conversions
2796 occur include: str for floats and complex numbers; the float and complex
2797 constructors; old-style and new-style numeric formatting; serialization and
2798 deserialization of floats and complex numbers using marshal, pickle and json;
2799 parsing of float and imaginary literals in Python code; Decimal-to-float
2800 conversion.
Mark Dickinsonb678de82009-11-19 18:41:49 +00002801
Georg Brandlba83f822010-03-14 09:50:54 +00002802 The conversions use a Python-adapted version of David Gay's well-known dtoa.c,
2803 providing correctly-rounded strtod and dtoa C functions. This code is
2804 supported on Windows, and on Unix-like platforms using gcc, icc or suncc as
2805 the C compiler. There may be a small number of platforms on which correct
2806 operation of this code cannot be guaranteed, so the code is not used: notably,
2807 this applies to platforms where the C double format is not IEEE 754 binary64,
2808 and to platforms on x86 hardware where the x87 FPU is set to 64-bit precision
2809 and Python's configure script is unable to determine how to change the FPU
2810 precision. On these platforms conversions use the platform strtod and dtoa,
2811 as before.

Georg Brandlba83f822010-03-14 09:50:54 +00002813- Issue #7117: Backport round implementation from Python 3.x. ``round()`` now
2814 uses the correctly-rounded string <-> float conversions described above (when
2815 available), and so produces correctly rounded results that will display nicely
2816 under the float repr. There are two related small changes: (1) round now
2817 accepts any class with an ``__index__()`` method for its second argument (but
2818 no longer accepts floats for the second argument), and (2) an excessively
2819 large second integer argument (e.g., ``round(1.234, 10**100)``) no longer
2820 raises an exception.

Georg Brandlba83f822010-03-14 09:50:54 +00002967- Issue #5920: For ``float.__format__()``, change the behavior with the empty
2968 presentation type (that is, not one of 'e', 'f', 'g', or 'n') to be like 'g'
2969 but with at least one decimal point and with a default precision
2970 of 12. Previously, the behavior the same but with a default precision of 6.
2971 This more closely matches ``str()``, and reduces surprises when adding
2972 alignment flags to the empty presentation type. This also affects the new
2973 complex.__format__ in the same way.

3164
Georg Brandlba83f822010-03-14 09:50:54 +00003165- Issue #3689: The list reversed iterator now supports __length_hint__ instead

3170
Georg Brandlba83f822010-03-14 09:50:54 +00003171- Issue #4233: Changed semantic of ``_fileio.FileIO``'s ``close()`` method on
3172 file objects with closefd=False. The file descriptor is still kept open but
3173 the file object behaves like a closed file. The ``FileIO`` object also got a
3174 new readonly attribute ``closefd``.

Benjamin Peterson399b1fe2008-10-25 02:53:28 +00003194- Using ``nonlocal`` as a variable name will now raise a Py3k SyntaxWarning

Georg Brandlba83f822010-03-14 09:50:54 +00003197- On windows, ``os.chdir()`` given unicode was not working if
3198 GetCurrentDirectoryW returned a path longer than MAX_PATH. (But It's doubtful
3199 this code path is really executed because I cannot move to such directory on
3200 win2k)

Georg Brandlba83f822010-03-14 09:50:54 +00003202- Issue #4069: When ``set.remove(element)`` is used with a set element, the
3203 element is temporarily replaced with an equivalent frozenset. But the
3204 eventual KeyError would always report the empty ``frozenset()`` as the missing
3205 key. Now it correctly refers to the initial element.

3224
Walter Dörwalded960ac2009-05-03 22:36:33 +00003225- Issue #5108: Handle %s like %S and %R in PyUnicode_FromFormatV(): Call
3226 PyUnicode_DecodeUTF8() once, remember the result and output it in a second
3227 step. This avoids problems with counting UTF-8 bytes that ignores the effect
3228 of using the replace error handler in PyUnicode_DecodeUTF8().
3229
Walter Dörwald726ba8e2009-05-06 14:32:35 +00003230- Issue #3739: The unicode-internal encoder now reports the number of characters
3231 consumed like any other encoder (instead of the number of bytes).
3232
Georg Brandlba83f822010-03-14 09:50:54 +00003233- Issue #2422: When compiled with the ``--with-valgrind`` option, the pymalloc
3234 allocator will be automatically disabled when running under Valgrind. This
3235 gives improved memory leak detection when running under Valgrind, while taking
3236 advantage of pymalloc at other times.

Martin v. Löwis9fa5a282008-09-11 06:53:30 +00004601- Issue #3642: Suppress warning in obmalloc when size_t is larger than uint.
4602
Amaury Forgeot d'Arc05e34492008-09-10 22:04:45 +00004603- Issue #3743: In a few places, PY_FORMAT_SIZE_T was incorrectly used with
4604 PyString_FromFormat or PyErr_Format to display size_t values. The macro
4605 PY_FORMAT_SIZE_T is designed to select the correct format for the OS
4606 ``printf`` function, whereas PyString_FromFormat has an independent
4607 implementation and uses "%zd" on all platforms for size_t values.
4608 This makes a difference on win64, where ``printf`` needs "%Id" to display
4609 64bit values.

Benjamin Peterson97179b02008-09-09 20:55:01 +00004611- Issue #3634: _weakref.ref(Exception).__init__() gave invalid return value on

Amaury Forgeot d'Arcd3ffb892008-09-09 07:24:30 +00004614- Issue #3777: long() applied to a float object now always return a long
4615 object; previously an int would be returned for small values. the __long__
4616 method is allowed to return either an int or a long, but the behaviour of
4617 float objects should not change to respect backward compatibility.

Amaury Forgeot d'Arc3571fbf2008-09-01 19:52:00 +00004619- Issue #3751: str.rpartition would perform a left-partition when called with
4620 a unicode argument.

Vinay Sajip35e3b032008-09-01 14:33:59 +00004625 PyArg_ParseTuple and friends, which occurred when the argument for "s*"
Antoine Pitroud4ae97b2008-08-29 18:39:48 +00004626 was correctly parsed but parsing of subsequent arguments failed.
4627
Vinay Sajip35e3b032008-09-01 14:33:59 +00004628- Issue #2534: speed up isinstance() and issubclass() by 50-70%, so as to
Antoine Pitrou0668c622008-08-26 22:42:08 +00004629 match Python 2.5 speed despite the __instancecheck__ / __subclasscheck__
4630 mechanism. In the process, fix a bug where isinstance() and issubclass(),
4631 when given a tuple of classes as second argument, were looking up
4632 __instancecheck__ / __subclasscheck__ on the tuple rather than on each
4633 type object.
4634
Neal Norwitz18aa3882008-08-24 05:04:52 +00004635- Fix crashes on memory allocation failure found with failmalloc.

Brett Cannon1eaf0742008-09-02 01:25:16 +00004704 warnings.catch_warnings() along with some API cleanup. Expanding the tests

4778-----------------
4779
Guido van Rossumf8402962008-08-20 15:01:50 +00004780- Issue #1878: Remove Py_TPFLAGS_HAVE_VERSION_TAG from
4781 Py_TPFLAGS_DEFAULT when not building the core. This means 3rd party
4782 extensions do not automatically benefit from the class attribute
4783 cache; they will have to explicitly add Py_TPFLAGS_HAVE_VERSION_TAG
4784 to their tp_flags field if they care. This is a backwards
4785 compatibility feature; in 3.0, all types will use the cache by
4786 default.
4787
Benjamin Petersonf647dc12008-08-20 01:27:30 +00004788- Keyword arguments can now follow starred arguments. (``f(a, *args,
4789 keyword=23)`` is now valid syntax.)
4790
Thomas Heller0ad5ae02008-08-19 19:25:04 +00004791- ctypes function pointers that are COM methods have a boolean True
4792 value again.

4796 and introducing s*.
4797
Georg Brandl1e13ea92008-08-11 09:07:59 +00004798- Issue #3537: Fix an assertion failure when an empty but presized dict
4799 object was stored in the freelist.

Mark Dickinsonb6467572008-08-04 21:30:09 +00004801- Issue #1481296: Make long(float('nan')) and int(float('nan')) raise
4802 ValueError consistently across platforms.
4803
Amaury Forgeot d'Arc39fd6722008-07-31 21:28:03 +00004804- Issue #3479: On platforms where sizeof(int) is smaller than sizeof(long)
4805 (64bit Unix, for example), unichr() would truncate its argument and return
4806 u'\x00' for unichr(2**32). Now it properly raises an OverflowError.

Antoine Pitrou92f82162008-07-25 22:22:08 +00004813- Issue #1819: function calls with several named parameters are now on
4814 average 35% faster (as measured by pybench).
4815
Amaury Forgeot d'Arce4921fe2008-07-21 22:00:38 +00004816- Issue #2378: An unexpected UnboundLocalError or NameError could appear when
4817 the python debugger steps into a class statement: the free variables (local
4818 variables defined in an outer scope) would be deleted from the outer scope.
4819
Gregory P. Smith0470bab2008-07-22 04:46:32 +00004820- Issue #2620: Overflow checking when allocating or reallocating memory
4821 was not always being done properly in some python types and extension
4822 modules. PyMem_MALLOC, PyMem_REALLOC, PyMem_NEW and PyMem_RESIZE have
4823 all been updated to perform better checks and places in the code that
4824 would previously leak memory on the error path when such an allocation
4825 failed have been fixed.

Benjamin Petersone977ad42008-08-20 01:42:01 +00004832- The methods ``is_in_tuple()``, ``is_vararg()``, and ``is_keywordarg()`` of
4833 symtable.Symbol have been deprecated for removal in 3.0 and the next release.
4834
Amaury Forgeot d'Arc351ffb82008-08-18 19:23:47 +00004835- Issue #2234: distutils failed for some versions of the cygwin compiler. The
4836 version reported by these tools does not necessarily follow the python
4837 version numbering scheme, so the module is less strict when parsing it.
4838
Nick Coghlanf70385a2008-08-18 12:42:46 +00004839- Issue #2235: Added Py3k warnings for types which will become unhashable
4840 under the stricter __hash__ inheritance rules in 3.0. Several types
4841 which did not meet the rules for hash invariants and were already
4842 unhashable in 3.0 have now been explicitly flagged as unhashable in
4843 2.6 as well (collections.Mapping, collections.Set, unittest.TestSuite,
4844 xml.dom.minidom.NamedNodeMap, numbers.Number, UserList.UserList)
4845
Brett Cannon88f801d2008-08-18 00:46:22 +00004846- Update __all__ for cookielib, csv, os, urllib2, and weakref to include things
4847 imported into the module but exposed as part of the module's API.
4848
Brett Cannon7b96f072008-08-18 00:41:11 +00004849- Remove an unneeded import of abc.ABCMeta from 'inspect'.
4850

4852
Brett Cannon25c9d6a2008-08-17 22:10:11 +00004853- Remove unneeded imports of 'warnings' from shelve, filecmp, and dummy_thread.
4854
Hirokazu Yamamoto41a81eb2008-08-17 13:10:46 +00004855- Issue #3575: Incremental decoder's decode function now takes bytearray
4856 by using 's*' instead of 't#'.
4857
Mark Dickinson3e4caeb2009-02-21 20:27:01 +00004858- Issue #2222: Fixed reference leak when occurred os.rename()
Hirokazu Yamamoto7f30a682008-08-17 09:46:56 +00004859 fails unicode conversion on 2nd parameter. (windows only)
4860
Georg Brandl222e2082010-08-01 22:27:39 +00004861- Issue #2464: urllib2 now supports a malformation in the URL received
Facundo Batista94f243a2008-08-17 03:38:39 +00004862 in a redirect.
4863
Brett Cannonabe423e2008-08-16 21:47:07 +00004864- Silence the DeprecationWarning raised when importing mimetools in
Brett Cannon721b1452008-08-16 22:00:27 +00004865 BaseHTTPServer, cgi (and rfc822), httplib.
Brett Cannonabe423e2008-08-16 21:47:07 +00004866
Facundo Batistaeb90b782008-08-16 14:44:07 +00004867- Issue #2776: fixed small issue when handling an URL with double slash
4868 after a 302 response in the case of not going through a proxy.
4869
Antoine Pitroub90a8be2008-08-15 21:03:21 +00004870- Issue #2676: in the email package, content-type parsing was hanging on
4871 pathological input because of quadratic or exponential behaviour of a
4872 regular expression.
4873
Antoine Pitrou11ec65d2008-08-14 21:04:30 +00004874- Issue #3476: binary buffered reading through the new "io" library is now
4875 thread-safe.
4876
Brett Cannonbf3157b2008-08-14 05:00:03 +00004877- Silence the DeprecationWarning of rfc822 when it is imported by mimetools
4878 since mimetools itself is deprecated. Because modules are cached, all
4879 subsequent imports of rfc822 will not raise a visible DeprecationWarning.
4880
Antoine Pitrou9fcd4b32008-08-11 17:21:36 +00004881- Issue #3134: shutil referenced undefined WindowsError symbol.

4884 menu entries were not deleted.
4885
Brett Cannon83e81842008-08-09 23:30:55 +00004886- Copied the implementation of reduce() to _functools.reduce() to have a
4887 version that did not raise a DeprecationWarning under -3.
4888
Antoine Pitrou76b8bee2008-08-09 17:27:23 +00004889- Issue #3205: When iterating over a BZ2File fails allocating memory, raise
4890 a MemoryError rather than silently stop the iteration.
4891
Guido van Rossum59ce9012008-08-09 14:55:34 +00004892- Issue #3487: sre "bytecode" validator. Passing invalid "re-bytecode"
4893 to _sre.compile() will now be rejected. This should not affect anybody
4894 since the re.compile() function never generates invalid re-bytecode.
4895
Skip Montanaroa032bf42008-08-08 22:52:51 +00004896- Issue #3436: Make csv.DictReader's fieldnames attribute a property so that
4897 upon first access it can be automatically initialized from the csv file if
4898 it wasn't initialized during instantiation.
4899
Brett Cannon3aa2a492008-08-06 22:28:09 +00004900- Issue #2338: Create imp.reload() to help with transitioning to Python 3.0 as
4901 the reload() built-in has been removed.
4902
Brett Cannon7e30b672008-08-04 21:52:25 +00004903- Changed code in the following modules/packages to remove warnings raised
Brett Cannonc1b76e42008-08-09 23:06:16 +00004904 while running under the ``-3`` flag: aifc, asynchat, asyncore, bdb, bsddb,

4912 raised an AttributeError.
4913
Benjamin Peterson01a24322008-07-28 23:35:27 +00004914- Issue #2523: Fix quadratic behaviour when read()ing a binary file without
Antoine Pitroude781a42008-08-09 12:43:23 +00004915 asking for a specific length. This problem only affected files opened
4916 using the new "io" module, not the built-in open() function.
Benjamin Peterson01a24322008-07-28 23:35:27 +00004917

Antoine Pitrou5fdfa3e2008-07-25 19:42:26 +00004941- Issue #3394: zipfile.writestr sets external attributes when passed a
4942 file name rather than a ZipInfo instance, so files are extracted with
4943 mode 0600 rather than 000 under Unix.
4944
Gregory P. Smitha36f8fe2008-08-04 00:13:29 +00004945- Issue #1857: subprocess.Popen.poll gained an additional _deadstate keyword

4958 interaction with the tp_hash slot (added in 2.6b2) are now documented
4959
Nick Coghlan2a0c2b12008-08-04 12:47:17 +00004960- Issue #643841: The language reference now provides more detailed
4961 coverage of the lookup process for special methods. The disclaimers
4962 regarding lack of coverage of new-style classes have also been
4963 removed, since the coverage is now fairly reasonable.

4967================================
4968
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00004969*Release date: 17-Jul-2008*
4970
Raymond Hettingere3ae6552008-06-20 04:18:15 +00004971Core and Builtins
4972-----------------
4973
Georg Brandl3e483f62008-07-16 22:57:41 +00004974- Issue #3156: Fix inconsistent behavior of the bytearray type: all
4975 its methods now allow for items objects that can be converted to
4976 an integer using operator.index().
4977
Mark Dickinson64b7e502008-07-16 09:40:03 +00004978- Issue #3360: Fix incorrect parsing of '020000000000.0', which
4979 produced a ValueError instead of giving the correct float.
4980
Eric Smitha5fa5a22008-07-16 00:11:49 +00004981- Issue #3083: Add alternate (#) formatting for bin, oct, hex output
4982 for str.format(). This adds the prefix 0b, 0o, or 0x, respectively.
4983
Mark Dickinson7103aa42008-07-15 19:08:33 +00004984- Issue #3008: the float type has a new instance method 'float.hex'
4985 and a new class method 'float.fromhex' to convert floating-point
4986 numbers to and from hexadecimal strings, respectively.
4987
Nick Coghlan6d6bd442008-07-15 15:40:22 +00004988- Issue #2235: __hash__ is once again inherited by default. To allow
4989 collections.Hashable to remain meaningful in the presence of the
4990 default hash implementation (object.__hash__), it is now possible
4991 to explicit block inheritance of hash by setting __hash__=None at
4992 the Python level, or tp_hash=PyObject_HashNotImplemented at the C
4993 level.
4994
Nick Coghlanb028f502008-07-13 14:52:36 +00004995- Issue #3221: Issue a RuntimeWarning instead of raising SystemError if
4996 the parent module cannot be found while performing an absolute import.
4997 This means that an incorrectly defined __package__ attribute will
4998 now only prevent relative imports in that module rather than causing
4999 all imports from that module to fail.
5000
Nick Coghlan14ff9942008-07-08 14:21:42 +00005001- Issue #2517: Allow unicode messages in Exceptions again by correctly
5002 bypassing the instance dictionary when looking up __unicode__ on
5003 new-style classes.
5004
Amaury Forgeot d'Arcbdd941f2008-07-01 20:38:04 +00005005- Issue #3242: Fix a crash inside the print statement, if sys.stdout is
5006 set to a custom object whose write() method happens to install
5007 another file in sys.stdout.
5008
Amaury Forgeot d'Arc1f40c8a2008-06-30 22:42:40 +00005009- Issue #3088: Corrected a race condition in classes derived from
5010 threading.local: the first member set by a thread could be saved in
5011 another thread's dictionary.
5012
Mark Dickinson1ec2fcd2008-06-20 14:53:43 +00005013- Issue #3004: Minor change to slice.indices(): the start and stop
5014 arguments are now treated identically, making the behaviour easier
5015 to describe and understand. For example, slice(None, -10,
5016 1).indices(9) now returns (0, 0, 1) instead of (0, -1, 1), and
5017 slice(None, 10, -1).indices(10) returns (9, 9, -1) instead of (9,
5018 10, -1).
5019
Georg Brandl278fc502008-07-19 12:46:12 +00005020- Issue #3219: Calling a function with repeated keyword arguments,
5021 f(a=2, a=23), would not cause a syntax error. This was a regression
5022 from 2.4 caused by the switch to the new compiler.
Benjamin Peterson175e4d92008-07-01 19:34:52 +00005023
Georg Brandl278fc502008-07-19 12:46:12 +00005024- Issue #2862: Make int and float freelist management consistent with
5025 other freelists. Changes their CompactFreeList apis into
5026 ClearFreeList apis and calls them via gc.collect().

Thomas Heller57adf222008-08-14 19:10:48 +00005031- Issue #3554: ctypes.string_at and ctypes.wstring_at did call Python
5032 api functions without holding the GIL, which could lead to a fatal
5033 error when they failed.
5034
Martin v. Löwisaabf4042008-08-02 07:20:25 +00005035- Issue #799428: Fix Tkinter.Misc._nametowidget to unwrap Tcl command objects.

5045
Vinay Sajip51e65192008-07-18 09:01:10 +00005046- Issue #3090: Fixed ARCHFLAGS parsing on OS/X

Amaury Forgeot d'Arc0f7cddc2008-07-06 21:34:39 +00005060- Issue #839496: SimpleHTTPServer used to open text files in text mode. This is
5061 both unnecessary (HTTP allows text content to be sent in several forms) and
Andrew M. Kuchlingcc3f2b12008-07-10 14:43:31 +00005062 wrong because the actual transmitted size could differ from the
Amaury Forgeot d'Arc0f7cddc2008-07-06 21:34:39 +00005063 content-length. The problem had been corrected in the 2.4 branch, but never
5064 merged into trunk.

Nick Coghlanc060b0e2008-07-02 13:09:19 +00005079- Issue #3190: Pydoc now hides the automatic module attribute __package__ (the
5080 handling is now the same as that of other special attributes like __name__).
5081
Brett Cannon8bb8fa52008-07-02 01:57:08 +00005082- Issue #2885 (partial): The urllib.urlopen() function has been deprecated for

5471 mode or even as a 4-way universal binary (that is, PPC, i386,
Georg Brandl5cc774e2008-06-11 20:28:06 +00005472 PPC64 and x86_64 support in one binary).
Ronald Oussoren5640ce22008-06-05 12:58:24 +00005473
5474 This is controlled by the configure argument ``--with-universal-archs``:
5475
5476 - ``--with-universal-archs=all``: install 4-way universal
5477
5478 - ``--with-universal-archs=32-bit``: install 2-way universal, 32-bit (the default)
5479
5480 - ``--with-universal-archs=64-bit``: install 2-way universal, 64-bit
5481
5482 This option should be used in combination with ``--enable-universalsdk=``.
5483
5484 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 +00005534- Issue #1631171: Re-implement the 'warnings' module in C (the
5535 original Python code has been kept as backup). This will allow for
5536 using the 'warning's machinery in such places as the parser where
5537 use of pure Python code is not possible. Both the ``showarning()``
5538 and ``formatwarning()`` gain an optional 'line' argument which is
5539 not called by default for backwards-compatibility reasons. Setting
5540 ``warnings.showwarning()`` to an implementation that lacks support
5541 for the ``line`` argument will raise a DeprecationWarning.

Georg Brandl3ee81df2008-05-17 18:14:43 +00005583- Issue #2513: distutils on Windows is now capable of cross-compiling
Mark Hammond495cf992008-04-07 01:53:39 +00005584 extension modules between 32 and 64 bit platforms. See the distutls

Georg Brandl3ee81df2008-05-17 18:14:43 +00005604- Issue #2550: The approach used by client/server code for obtaining
5605 ports to listen on in network-oriented tests has been refined in an
5606 effort to facilitate running multiple instances of the entire
5607 regression test suite in parallel without issue.
5608 test_support.bind_port() has been fixed such that it will always
5609 return a unique port -- which wasn't always the case with the
5610 previous implementation, especially if socket options had been set
5611 that affected address reuse (i.e. SO_REUSEADDR, SO_REUSEPORT). The
5612 new implementation of bind_port() will actually raise an exception
5613 if it is passed an AF_INET/SOCK_STREAM socket with either the
5614 SO_REUSEADDR or SO_REUSEPORT socket option set. Furthermore, if
5615 available, bind_port() will set the SO_EXCLUSIVEADDRUSE option on
5616 the socket it's been passed. This currently only applies to
5617 Windows. This option prevents any other sockets from binding to the
5618 host/port we've bound to, thus removing the possibility of the
5619 'non-deterministic' behaviour, as Microsoft puts it, that occurs
5620 when a second SOCK_STREAM socket binds and accepts to a host/port
5621 that's already been bound by another socket. The optional preferred
5622 port parameter to bind_port() has been removed. Under no
5623 circumstances should tests be hard coding ports!
5624
5625 test_support.find_unused_port() has also been introduced, which will
5626 pass a temporary socket object to bind_port() in order to obtain an
5627 unused port. The temporary socket object is then closed and
5628 deleted, and the port is returned. This method should only be used
5629 for obtaining an unused port in order to pass to an external program
5630 (i.e. the -accept [port] argument to openssl's s_server mode) or as
5631 a parameter to a server-oriented class that doesn't give you direct
5632 access to the underlying socket used.
5633
5634 Finally, test_support.HOST has been introduced, which should be used
5635 for the host argument of any relevant socket calls (i.e. bind and
5636 connect).
Trent Nelsone41b0062008-04-08 23:47:30 +00005637
5638 The following tests were updated to following the new conventions:
Georg Brandl3ee81df2008-05-17 18:14:43 +00005639 test_socket, test_smtplib, test_asyncore, test_ssl, test_httplib,
Trent Nelsone41b0062008-04-08 23:47:30 +00005640 test_poplib, test_ftplib, test_telnetlib, test_socketserver,
5641 test_asynchat and test_socket_ssl.
5642
Georg Brandl3ee81df2008-05-17 18:14:43 +00005643 It is now possible for multiple instances of the regression test
5644 suite to run in parallel without issue.

Christian Heimes5224d282008-02-23 15:01:05 +00005919
Vinay Sajipb7edfc42008-04-02 21:10:23 +00005920- Issue #1881: An internal parser limit has been increased. Also see
Georg Brandl222e2082010-08-01 22:27:39 +00005921 issue #215555 for a discussion.
Facundo Batistafc2d0102008-02-23 12:01:13 +00005922
Eric Smitha73fbe72008-02-23 03:09:44 +00005923- Added the future_builtins module, which contains hex() and oct().
5924 These are the PEP 3127 version of these functions, designed to be
5925 compatible with the hex() and oct() builtins from Python 3.0. They
5926 differ slightly in their output formats from the existing, unchanged
5927 Python 2.6 builtins. The expected usage of the future_builtins
5928 module is:
5929 from future_builtins import hex, oct
5930
Eric Smith7ef40bf2008-02-20 23:34:22 +00005931- Issue #1600: Modifed PyOS_ascii_formatd to use at most 2 digit
5932 exponents for exponents with absolute value < 100. Follows C99
5933 standard. This is a change on Windows, which would use 3 digits.
5934 Also, added 'n' to the formats that PyOS_ascii_formatd understands,
5935 so that any alterations it does to the resulting string will be
5936 available in stringlib/formatter.h (for float.__format__).
5937
Eric Smith5a3c1352008-02-19 13:21:56 +00005938- Implemented PEP 3101, Advanced String Formatting. This adds a new
5939 builtin format(); a format() method for str and unicode; a
5940 __format__() method to object, str, unicode, int, long, float, and
5941 datetime; the class string.Formatter; and the C API
5942 PyObject_Format().
5943
Georg Brandl3ee81df2008-05-17 18:14:43 +00005944- Fixed several potential crashes, all caused by specially crafted
5945 __del__ methods exploiting objects in temporarily inconsistent
5946 state.
Amaury Forgeot d'Arc632fad32008-02-16 20:55:24 +00005947
Vinay Sajipb7edfc42008-04-02 21:10:23 +00005948- Issue #2115: Important speedup in setting __slot__ attributes. Also
Georg Brandl3ee81df2008-05-17 18:14:43 +00005949 prevent a possible crash: an Abstract Base Class would try to access
5950 a slot on a registered virtual subclass.
Amaury Forgeot d'Arc60d6c7f2008-02-15 21:22:45 +00005951
Georg Brandl3ee81df2008-05-17 18:14:43 +00005952- Fixed repr() and str() of complex numbers with infinity or nan as
5953 real or imaginary part.
Christian Heimes2f0da532008-02-15 06:57:08 +00005954
Georg Brandl3ee81df2008-05-17 18:14:43 +00005955- Clear all free lists during a gc.collect() of the highest generation
5956 in order to allow pymalloc to free more arenas. Python may give back
5957 memory to the OS earlier.
Christian Heimes3b718a72008-02-14 12:47:33 +00005958
Georg Brandl3ee81df2008-05-17 18:14:43 +00005959- Issue #2045: Fix an infinite recursion triggered when printing a
5960 subclass of collections.defaultdict, if its default_factory is set
5961 to a bound method.
Amaury Forgeot d'Arcb01aa432008-02-08 00:56:02 +00005962
Christian Heimesf75dbef2008-02-08 00:11:31 +00005963- Fixed a minor memory leak in dictobject.c. The content of the free
5964 list was not freed on interpreter shutdown.
5965
Georg Brandl21e99f42010-03-07 15:23:59 +00005966- Limit free list of method and built-in function objects to 256
Georg Brandl3ee81df2008-05-17 18:14:43 +00005967 entries each.
Christian Heimes6075a822008-02-06 12:44:34 +00005968
Georg Brandl3ee81df2008-05-17 18:14:43 +00005969- Patch #1953: Added ``sys._compact_freelists()`` and the C API
5970 functions ``PyInt_CompactFreeList`` and ``PyFloat_CompactFreeList``
Christian Heimes422051a2008-02-04 18:00:12 +00005971 to compact the internal free lists of pre-allocted ints and floats.
5972
Georg Brandl3ee81df2008-05-17 18:14:43 +00005973- Issue #1983: Fixed return type of fork(), fork1() and forkpty()
5974 calls. Python expected the return type int but the fork familie
5975 returns pi_t.
Christian Heimes951cc0f2008-01-31 23:08:23 +00005976
Georg Brandl3ee81df2008-05-17 18:14:43 +00005977- Issue #1678380: Fix a bug that identifies 0j and -0j when they
5978 appear in the same code unit.
Mark Dickinson105be772008-01-31 22:17:37 +00005979
Georg Brandl3ee81df2008-05-17 18:14:43 +00005980- Issue #2025: Add tuple.count() and tuple.index() methods to comply
5981 with the collections.Sequence API.
Raymond Hettinger5b07ebc2008-02-07 00:54:20 +00005982
Georg Brandl3ee81df2008-05-17 18:14:43 +00005983- Patch #1970 by Antoine Pitrou: Speedup unicode whitespace and
5984 linebreak detection
Christian Heimes4d4f2702008-01-30 11:32:37 +00005985
Georg Brandl3ee81df2008-05-17 18:14:43 +00005986- Added ``PyType_ClearCache()`` and ``sys._clear_type_cache`` to clear
5987 the internal lookup cache for ref leak tests.
Christian Heimes908caac2008-01-27 23:34:59 +00005988
Georg Brandl3ee81df2008-05-17 18:14:43 +00005989- Patch #1473257: generator objects gain a gi_code attribute. This is
5990 the same object as the func_code attribute of the function that
5991 produced the generator.
Georg Brandl0cdf9a32008-01-26 14:14:20 +00005992
Georg Brandl3ee81df2008-05-17 18:14:43 +00005993- Issue #1920: "while 0" statements were completely removed by the
5994 compiler, even in the presence of an "else" clause, which is
5995 supposed to be run when the condition is false. Now the compiler
5996 correctly emits bytecode for the "else" suite.
Amaury Forgeot d'Arc31eaafe2008-01-24 22:59:25 +00005997
Guido van Rossumeead05f2008-01-24 18:21:02 +00005998- A few crashers fixed: weakref_in_del.py (issue #1377858);
5999 loosing_dict_ref.py (issue #1303614, test67.py);
6000 borrowed_ref_[34].py (not in tracker).
6001
Vinay Sajipd7cf32e2008-01-24 12:43:33 +00006002- Issue #1069410: The "can't load dll" message box on Windows is
Christian Heimesb2302ba2008-01-23 17:15:06 +00006003 suppressed while an extension is loaded by calling SetErrorMode in
6004 dynload_win.c. The error is still reported properly.
6005
Georg Brandl3ee81df2008-05-17 18:14:43 +00006006- Issue #1915: Python compiles with --enable-unicode=no again. However
Christian Heimes082c9b02008-01-23 14:20:50 +00006007 several extension methods and modules do not work without unicode
6008 support.
6009
Georg Brandl26543b12008-01-21 18:36:51 +00006010- Issue #1882: when compiling code from a string, encoding cookies in the
6011 second line of code were not always recognized correctly.
6012
Georg Brandl14404b62008-01-19 19:27:05 +00006013- Issue #1679: "0x" was taken as a valid integer literal.
6014
Georg Brandl6caad7d2008-01-26 14:19:22 +00006015- Issue #1865: ``bytes`` as an alias for ``str`` and b"" as an alias "" were
Christian Heimes288e89a2008-01-18 18:24:07 +00006016 added.
6017
Christian Heimesc94e2b52008-01-14 04:13:37 +00006018- sys.float_info / PyFloat_GetInfo: The floating point information
6019 object was converted from a dict to a specialized structseq object.
6020
Georg Brandl3ee81df2008-05-17 18:14:43 +00006021- Patch #1816: Added sys.flags structseq. It exposes the status of
6022 most command line arguments and PYTHON* environment variables.
Christian Heimesf31b69f2008-01-14 03:42:48 +00006023
Georg Brandl3ee81df2008-05-17 18:14:43 +00006024- Objects/structseq.c: Implemented new structseq representation. The
6025 patch makes structseqs (e.g. the return value of os.stat) more
6026 readable.
Christian Heimes9c201962008-01-14 03:33:52 +00006027
Georg Brandl3ee81df2008-05-17 18:14:43 +00006028- Patch #1700288: added a type attribute cache that caches method
6029 accesses, resulting in speedups in heavily object-oriented code.
Amaury Forgeot d'Arce4c270c2008-01-14 00:29:41 +00006030
Neal Norwitz3fc15b82008-01-10 05:42:58 +00006031- Bug #1776: __import__() no longer accepts filenames on any platform.
6032 The first parameter to __import__() must be a valid module name.
Christian Heimes3403f152008-01-09 19:56:33 +00006033
Georg Brandlaed6c662008-01-07 17:25:53 +00006034- Patch #1668: renamed THREADDEBUG envvar to PYTHONTHREADDEBUG.
6035
Georg Brandl3ee81df2008-05-17 18:14:43 +00006036- Patch #602345: Add -B command line option, PYTHONDONTWRITEBYTECODE
6037 envvar and sys.dont_write_bytecode attribute. All these can be set
6038 to forbid Python to attempt to write compiled bytecode files.
Georg Brandl2da0fce2008-01-07 17:09:35 +00006039
Georg Brandl3ee81df2008-05-17 18:14:43 +00006040- Improve some exception messages when Windows fails to load an
6041 extension module. Now we get for example '%1 is not a valid Win32
6042 application' instead of 'error code 193'.
Amaury Forgeot d'Arce0b76952008-01-04 02:04:15 +00006043
Georg Brandl3ee81df2008-05-17 18:14:43 +00006044- Bug #1481296: Fixed long(float('nan')) != 0L.

Georg Brandl3ee81df2008-05-17 18:14:43 +00006046- Issue #1640: Added math.isinf(x), math.isnan(x) and math.copysign(x,
6047 y) functions.
Christian Heimese2ca4242008-01-03 20:23:15 +00006048
Christian Heimes0a8143f2007-12-18 23:22:54 +00006049- Issue #1635: Platform independent creation and representation of NaN
Georg Brandl3ee81df2008-05-17 18:14:43 +00006050 and INF. float("nan"), float("inf") and float("-inf") now work on
6051 every platform with IEEE 754 semantics.
Christian Heimes0a8143f2007-12-18 23:22:54 +00006052
Georg Brandl3ee81df2008-05-17 18:14:43 +00006053- Compiler now generates simpler and faster code for dictionary
6054 literals. The oparg for BUILD_MAP now indicates an estimated
6055 dictionary size. There is a new opcode, STORE_MAP, for adding
6056 entries to the dictionary.
Raymond Hettingerfd7ed402007-12-18 21:24:09 +00006057
Georg Brandl3ee81df2008-05-17 18:14:43 +00006058- Issue #1638: %zd configure test fails on Linux.

6071 __package__ attribute.
6072
Georg Brandl3ee81df2008-05-17 18:14:43 +00006073- Issue #1402: Fix a crash on exit, when another thread is still
6074 running, and if the deallocation of its frames somehow calls the
6075 PyGILState_Ensure() / PyGILState_Release() functions.

6086 file can now be directly executed by passing their name to the
6087 interpreter. The directory/zipfile is automatically inserted as the
6088 first entry in sys.path.
Nick Coghlan327a39b2007-11-18 11:56:28 +00006089
Georg Brandl3ee81df2008-05-17 18:14:43 +00006090- Issue #1265: Fix a problem with sys.settrace, if the tracing
6091 function uses a generator expression when at the same time the
6092 executed code is closing a paused generator.
Amaury Forgeot d'Arc0d75f092007-11-13 21:54:28 +00006093
Raymond Hettinger1760c8a2007-11-08 02:52:43 +00006094- sets and frozensets now have an isdisjoint() method.
6095
Raymond Hettinger3f8caa32007-10-24 01:28:33 +00006096- optimize the performance of builtin.sum().

Neal Norwitz44f326e2007-10-05 05:29:17 +00006098- Fix warnings found by the new version of the Coverity checker.
6099
Georg Brandl21e99f42010-03-07 15:23:59 +00006100- The enumerate() built-in function is no longer bounded to sequences
Georg Brandl3ee81df2008-05-17 18:14:43 +00006101 smaller than LONG_MAX. Formerly, it raised an OverflowError. Now,
6102 automatically shifts from ints to longs.
Raymond Hettinger8f669372007-10-03 21:18:11 +00006103
Georg Brandl3ee81df2008-05-17 18:14:43 +00006104- Issue #1686386: Tuple's tp_repr did not take into account the
6105 possibility of having a self-referential tuple, which is possible
6106 from C code. Nor did object's tp_str consider that a type's tp_str
6107 could do something that could lead to an inifinite recursion.
6108 Py_ReprEnter() and Py_EnterRecursiveCall(), respectively, fixed the
6109 issues.
Brett Cannon0b14f242007-09-30 19:45:10 +00006110
Georg Brandl3ee81df2008-05-17 18:14:43 +00006111- Issue #1164: It was possible to trigger deadlock when using the
6112 'print' statement to write to a file since the GIL was not released
6113 as needed. Now PyObject_Print() does the right thing along with
6114 various tp_print implementations of the built-in types and those in
6115 the collections module.
Brett Cannon01531592007-09-17 03:28:34 +00006116
Georg Brandl3ee81df2008-05-17 18:14:43 +00006117- Issue #1147: Exceptions were directly allowing string exceptions in
6118 their throw() method even though string exceptions no longer
6119 allowed.
Brett Cannon4c20bc42007-09-11 21:02:28 +00006120

Brett Cannon1e534b52007-09-07 04:18:30 +00006124- Issue #1202533: Fix infinite recursion calls triggered by calls to
Georg Brandl3ee81df2008-05-17 18:14:43 +00006125 PyObject_Call() never calling back out to Python code to trigger
6126 recursion depth updates/checks. Required the creation of a static
6127 RuntimeError instance in case normalizing an exception put the
6128 recursion check value past its limit. Fixes crashers
6129 infinite_rec_(1|2|4|5).py.
Brett Cannon1e534b52007-09-07 04:18:30 +00006130

Neal Norwitz0ac60192007-05-27 04:08:54 +00006144- Add new attribute names for function objects. All the func_* become
Georg Brandl3ee81df2008-05-17 18:14:43 +00006145 __*__ attributes. (Some already existed, e.g., __doc__ and
6146 __name__.)
Neal Norwitz0ac60192007-05-27 04:08:54 +00006147
Neal Norwitz8b2bfbc2007-05-23 06:35:32 +00006148- Add -3 option to the interpreter to warn about features that are
6149 deprecated and will be changed/removed in Python 3.0.
6150
Georg Brandl2134e752007-05-21 20:34:16 +00006151- Patch #1686487: you can now pass any mapping after '**' in function
6152 calls.
6153
Collin Winter62903052007-05-18 23:11:24 +00006154- except clauses may now be spelled either "except E, target:" or
Georg Brandl3ee81df2008-05-17 18:14:43 +00006155 "except E as target:". This is to provide forwards compatibility
6156 with Python 3.0.

Georg Brandl3ee81df2008-05-17 18:14:43 +00006160- Issue #1303614: don't expose object's __dict__ when the dict is
Georg Brandl21e99f42010-03-07 15:23:59 +00006161 inherited from a built-in base.

Vinay Sajip8549ce32007-05-06 17:53:37 +00006163- When __slots__ are set to a unicode string, make it work the same as
Neal Norwitzcbd9ee62007-04-14 05:25:50 +00006164 setting a plain string, ie don't expand to single letter identifiers.
6165
Raymond Hettinger13936692007-04-11 18:40:58 +00006166- Request #1191699: Slices can now be pickled.
6167
Raymond Hettinger4db5fe92007-04-12 04:10:00 +00006168- Request #1193128: str.translate() now allows a None argument for
6169 translations that only remove characters without re-mapping the
6170 remaining characters.
6171
Georg Brandl5cb76c12007-03-21 09:00:39 +00006172- Patch #1682205: a TypeError while unpacking an iterable is no longer
6173 masked by a generic one with the message "unpack non-sequence".

6176
Guido van Rossum143b5642007-03-23 04:58:42 +00006177- Bug #1683368: The object.__init__() and object.__new__() methods are
6178 now stricter in rejecting excess arguments. The only time when
6179 either allows excess arguments is when it is not overridden and the
6180 other one is. For backwards compatibility, when both are
6181 overridden, it is a deprecation warning (for now; maybe a Py3k
Guido van Rossum234b1ff2007-03-23 19:39:01 +00006182 warning later). Also, type.__init__() insists on the same signature
6183 as supported by type.__new__().

Georg Brandl3ee81df2008-05-17 18:14:43 +00006185- Patch #1675423: PyComplex_AsCComplex() now tries to convert an
6186 object to complex using its __complex__() method before falling back
6187 to the __float__() method. Therefore, the functions in the cmath
6188 module now can operate on objects that define a __complex__()
6189 method.

6200 its type.

Georg Brandl7b9c5552007-03-12 14:30:05 +00006207- Bug #1678647: write a newline after printing an exception in any
6208 case, even when converting the value to a string failed.
6209
Georg Brandl871f1bc2007-03-12 13:17:36 +00006210- The dir() function has been extended to call the __dir__() method on
Georg Brandl3ee81df2008-05-17 18:14:43 +00006211 its argument, if it exists. If not, it will work like before. This
6212 allows customizing the output of dir() in the presence of a
6213 __getattr__().

6223 raising a ValueError.
Collin Wintere38051d2007-03-09 20:33:07 +00006224
Georg Brandlaa2321b2007-03-07 00:40:28 +00006225- Patch #703779: unset __file__ in __main__ after running a file. This
Georg Brandl3ee81df2008-05-17 18:14:43 +00006226 makes the filenames the warning module prints much more sensible
6227 when a PYTHONSTARTUP file is used.

Georg Brandl0fca97a2007-03-05 22:28:08 +00006240- Patch #1674228: when assigning a slice (old-style), check for the
6241 sq_ass_slice instead of the sq_slice slot.
6242
Georg Brandl3ee81df2008-05-17 18:14:43 +00006243- When printing an unraisable error, don't print exceptions. before

Georg Brandl2c1375c2006-10-12 11:27:59 +00006295- Bug #1545497: when given an explicit base, int() did ignore NULs
6296 embedded in the string to convert.
6297
Georg Brandl846f73a2006-10-08 07:11:54 +00006298- Bug #1569998: break inside a try statement (outside a loop) is now

Neal Norwitzdac090d2006-09-05 03:53:08 +00006345- Bug #1520864: unpacking singleton tuples in list comprehensions and
Georg Brandl3ee81df2008-05-17 18:14:43 +00006346 generator expressions (x for x, in ... ) works again. Fixing this
6347 problem required changing the .pyc magic number. This means that
6348 .pyc files generated before 2.5c2 will be regenerated.

Georg Brandl3ee81df2008-05-17 18:14:43 +00007155- Issue #829951: In the smtplib module, SMTP.starttls() now complies
7156 with RFC 3207 and forgets any knowledge obtained from the server not
7157 obtained from the TLS negotiation itself. Patch contributed by Bill
7158 Fenner.
Gregory P. Smith2b3ba582008-01-17 08:03:17 +00007159
Georg Brandl3ee81df2008-05-17 18:14:43 +00007160- Issue #1339: The smtplib.SMTP class has been refactored a bit such
Gregory P. Smithbde4ae42008-01-17 08:35:49 +00007161 that the SMTP.starttls() caller no longer needs to call ehlo()
7162 beforehand. SMTP.starttls() now raises an exception of the server
Georg Brandl3ee81df2008-05-17 18:14:43 +00007163 does not claim to support starttls. Adds the
7164 SMTP.ehlo_or_helo_if_needed() method. Patch contributed by Bill
7165 Fenner.

7245 complex, tuple, list, dict, set, and frozenset. Formerly, it would
7246 silently miscode subclasses of those types. Now, it raises a
7247 ValueError instead.
Raymond Hettinger12e94202007-11-07 01:13:09 +00007248

Georg Brandl3ee81df2008-05-17 18:14:43 +00007263 time so that opening a database previously created with the DB_DUP
7264 or DB_DUPSORT flag set will keep the proper behavior on subsequent
7265 opens. Specifically: dictionary assignment to a DB object will
7266 replace all values for a given key when the database allows
7267 duplicate values. DB users should use DB.put(k, v) when they want
7268 to store duplicates; not DB[k] = v.
Gregory P. Smithec10a4a2007-11-05 02:32:26 +00007269

7275 characters with ASCII value less than 32. Also, it correctly quotes
7276 dots only if they occur on a single line, as opposed to the previous
7277 behavior of quoting dots if they are the second character of any
7278 line.
Georg Brandl4aef7272007-03-13 22:49:43 +00007279

Georg Brandl3ee81df2008-05-17 18:14:43 +00007684- Removed the macfs module. It had been deprecated since Python 2.5.
7685 This lead to the deprecation of macostools.touched() as it relied
7686 solely on macfs and was a no-op under OS X.
