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
61 delimiter in URLs.

202
Ned Deily87e82bb2011-06-28 19:52:59 -0700203- Issue #9516: On Mac OS X, change Distutils to no longer globally attempt to
204 check or set the MACOSX_DEPLOYMENT_TARGET environment variable for the
205 interpreter process. This could cause failures in non-Distutils subprocesses
206 and was unreliable since tests or user programs could modify the interpreter
207 environment after Distutils set it. Instead, have Distutils set the the
208 deployment target only in the environment of each build subprocess. It is
209 still possible to globally override the default by setting
210 MACOSX_DEPLOYMENT_TARGET before launching the interpreter; its value must be
211 greater or equal to the default value, the value with which the interpreter
212 was built.

222
Victor Stinnerc74a6ba2011-06-17 14:06:27 +0200223- Issue #12133: AbstractHTTPHandler.do_open() of urllib.request closes the HTTP
224 connection if its getresponse() method fails with a socket error. Patch
225 written by Ezio Melotti.
226
Benjamin Peterson0eb4ac42011-06-11 15:53:11 -0500227- Issue #9284: Allow inspect.findsource() to find the source of doctest
228 functions.
229

239
Barry Warsawc5643282011-07-19 17:06:30 -0400240- sys.setcheckinterval() now updates the current ticker count as well as
241 updating the check interval, so if the user decreases the check interval,
242 the ticker doesn't have to wind down to zero from the old starting point
243 before the new interval takes effect. And if the user increases the
244 interval, it makes sure the new limit takes effect right away rather have an
245 early task switch before recognizing the new interval.

Raymond Hettinger20397532010-09-12 02:11:45 +00001129- Issue #9825: removed __del__ from the definition of collections.OrderedDict.
1130 This prevents user-created self-referencing ordered dictionaries from
1131 becoming permanently uncollectable GC garbage. The downside is that
1132 removing __del__ means that the internal doubly-linked list has to wait for
1133 GC collection rather than freeing memory immediately when the refcnt drops
1134 to zero.

1143 original error is re-raised.

Ezio Melottiab2eb0e2010-06-05 19:21:32 +00001593- Issue #8271: during the decoding of an invalid UTF-8 byte sequence, only the
1594 start byte and the continuation byte(s) are now considered invalid, instead
1595 of the number of bytes specified by the start byte.
1596 E.g.: '\xf1\x80AB'.decode('utf-8', 'replace') now returns u'\ufffdAB' and
1597 replaces with U+FFFD only the start byte ('\xf1') and the continuation byte
1598 ('\x80') even if '\xf1' is the start byte of a 4-bytes sequence.

Mark Dickinson4ca7c3c2010-05-30 13:18:10 +00001607- Issue #8748: Fix two issues with comparisons between complex and integer
1608 objects. (1) The comparison could incorrectly return True in some cases
1609 (2**53+1 == complex(2**53) == 2**53), breaking transivity of equality.
1610 (2) The comparison raised an OverflowError for large integers, leading

Georg Brandlfee0f442010-05-22 21:26:21 +00001994- Issue #7994: Issue a PendingDeprecationWarning if object.__format__ is called
1995 with a non-empty format string. This is an effort to future-proof user
1996 code. If a derived class does not currently implement __format__ but later
1997 adds its own __format__, it would most likely break user code that had
Antoine Pitrou01a196a2011-01-02 20:05:11 +00001998 supplied a format string. This will be changed to a DeprecationWarning in
Georg Brandlfee0f442010-05-22 21:26:21 +00001999 Python 3.3 and it will be an error in Python 3.4.

Georg Brandlba83f822010-03-14 09:50:54 +00002492 file position when calling `truncate()`. It would previously change the file
2493 position to the given argument, which goes against the tradition of
Antoine Pitrouf3fa0742010-01-31 22:26:04 +00002494 ftruncate() and other truncation APIs. Patch by Pascal Chambon.

2497 class used to represent files stored inside an archive. The new
2498 implementation is significantly faster and can be wrapped in a

2500 where interleaved calls to ``read()`` and ``readline()`` give wrong results.

2589-----------------
2590
Georg Brandlba83f822010-03-14 09:50:54 +00002591- The ``__complex__()`` method is now looked up on the class of instances to
2592 make it consistent with other special methods.

Antoine Pitrou5b7139a2010-01-02 21:12:58 +00002594- Issue #7462: Implement the stringlib fast search algorithm for the `rfind`,

2596
Mark Dickinson1b34d252010-01-01 17:27:30 +00002597- Issue #5080: A number of functions and methods previously produced a
Georg Brandlba83f822010-03-14 09:50:54 +00002598 DeprecationWarning when passed a float argument where an integer was expected.
2599 These functions and methods now raise TypeError instead. The majority of the
2600 effects of this change are in the extension modules, but some core functions
2601 and methods are affected: notably the 'chr', 'range' and 'xrange' builtins,
2602 and many unicode/str methods.

2616 of integers: the result of a/b is now correctly rounded for ints a and b (at
2617 least on IEEE 754 platforms), and in particular does not depend on the
2618 internal representation of a long.

Ronald Oussoren92919a62009-12-24 13:30:58 +00002625 executables on OSX.
2626
Georg Brandlba83f822010-03-14 09:50:54 +00002627 These executables now work properly with the arch(1) command: ``arch -ppc
2628 python`` will start a universal binary version of python in PPC mode (unlike
2629 previous releases).

2769 to 'g' for large values.
Amaury Forgeot d'Arcd7288712009-12-01 21:51:04 +00002770

Georg Brandlba83f822010-03-14 09:50:54 +00002785- Issue #7117: ``repr(x)`` for a float x returns a result based on the shortest
2786 decimal string that's guaranteed to round back to x under correct rounding
2787 (with round-half-to-even rounding mode). Previously it gave a string based on
2788 rounding x to 17 decimal digits. repr(x) for a complex number behaves
2789 similarly. On platforms where the correctly-rounded strtod and dtoa code is
2790 not supported (see below), repr is unchanged.
Mark Dickinsonb678de82009-11-19 18:41:49 +00002791
Georg Brandlba83f822010-03-14 09:50:54 +00002792- Issue #7117: On almost all platforms: float-to-string and string-to-float
2793 conversions within Python are now correctly rounded. Places these conversions
2794 occur include: str for floats and complex numbers; the float and complex
2795 constructors; old-style and new-style numeric formatting; serialization and
2796 deserialization of floats and complex numbers using marshal, pickle and json;
2797 parsing of float and imaginary literals in Python code; Decimal-to-float
2798 conversion.
Mark Dickinsonb678de82009-11-19 18:41:49 +00002799
Georg Brandlba83f822010-03-14 09:50:54 +00002800 The conversions use a Python-adapted version of David Gay's well-known dtoa.c,
2801 providing correctly-rounded strtod and dtoa C functions. This code is
2802 supported on Windows, and on Unix-like platforms using gcc, icc or suncc as
2803 the C compiler. There may be a small number of platforms on which correct
2804 operation of this code cannot be guaranteed, so the code is not used: notably,
2805 this applies to platforms where the C double format is not IEEE 754 binary64,
2806 and to platforms on x86 hardware where the x87 FPU is set to 64-bit precision
2807 and Python's configure script is unable to determine how to change the FPU
2808 precision. On these platforms conversions use the platform strtod and dtoa,
2809 as before.

Georg Brandlba83f822010-03-14 09:50:54 +00002811- Issue #7117: Backport round implementation from Python 3.x. ``round()`` now
2812 uses the correctly-rounded string <-> float conversions described above (when
2813 available), and so produces correctly rounded results that will display nicely
2814 under the float repr. There are two related small changes: (1) round now
2815 accepts any class with an ``__index__()`` method for its second argument (but
2816 no longer accepts floats for the second argument), and (2) an excessively
2817 large second integer argument (e.g., ``round(1.234, 10**100)``) no longer
2818 raises an exception.

Georg Brandlba83f822010-03-14 09:50:54 +00002965- Issue #5920: For ``float.__format__()``, change the behavior with the empty
2966 presentation type (that is, not one of 'e', 'f', 'g', or 'n') to be like 'g'
2967 but with at least one decimal point and with a default precision
2968 of 12. Previously, the behavior the same but with a default precision of 6.
2969 This more closely matches ``str()``, and reduces surprises when adding
2970 alignment flags to the empty presentation type. This also affects the new
2971 complex.__format__ in the same way.

3162
Georg Brandlba83f822010-03-14 09:50:54 +00003163- Issue #3689: The list reversed iterator now supports __length_hint__ instead

3168
Georg Brandlba83f822010-03-14 09:50:54 +00003169- Issue #4233: Changed semantic of ``_fileio.FileIO``'s ``close()`` method on
3170 file objects with closefd=False. The file descriptor is still kept open but
3171 the file object behaves like a closed file. The ``FileIO`` object also got a
3172 new readonly attribute ``closefd``.

Benjamin Peterson399b1fe2008-10-25 02:53:28 +00003192- Using ``nonlocal`` as a variable name will now raise a Py3k SyntaxWarning

Georg Brandlba83f822010-03-14 09:50:54 +00003195- On windows, ``os.chdir()`` given unicode was not working if
3196 GetCurrentDirectoryW returned a path longer than MAX_PATH. (But It's doubtful
3197 this code path is really executed because I cannot move to such directory on
3198 win2k)

Georg Brandlba83f822010-03-14 09:50:54 +00003200- Issue #4069: When ``set.remove(element)`` is used with a set element, the
3201 element is temporarily replaced with an equivalent frozenset. But the
3202 eventual KeyError would always report the empty ``frozenset()`` as the missing
3203 key. Now it correctly refers to the initial element.

3222
Walter Dörwalded960ac2009-05-03 22:36:33 +00003223- Issue #5108: Handle %s like %S and %R in PyUnicode_FromFormatV(): Call
3224 PyUnicode_DecodeUTF8() once, remember the result and output it in a second
3225 step. This avoids problems with counting UTF-8 bytes that ignores the effect
3226 of using the replace error handler in PyUnicode_DecodeUTF8().
3227
Walter Dörwald726ba8e2009-05-06 14:32:35 +00003228- Issue #3739: The unicode-internal encoder now reports the number of characters
3229 consumed like any other encoder (instead of the number of bytes).
3230
Georg Brandlba83f822010-03-14 09:50:54 +00003231- Issue #2422: When compiled with the ``--with-valgrind`` option, the pymalloc
3232 allocator will be automatically disabled when running under Valgrind. This
3233 gives improved memory leak detection when running under Valgrind, while taking
3234 advantage of pymalloc at other times.

4401 __long__ method could be packed by 'q', 'Q', '*q', '*Q'; for x with
4402 neither __int__ nor __long__, TypeError used to be raised (with a

Martin v. Löwis9fa5a282008-09-11 06:53:30 +00004599- Issue #3642: Suppress warning in obmalloc when size_t is larger than uint.
4600
Amaury Forgeot d'Arc05e34492008-09-10 22:04:45 +00004601- Issue #3743: In a few places, PY_FORMAT_SIZE_T was incorrectly used with
4602 PyString_FromFormat or PyErr_Format to display size_t values. The macro
4603 PY_FORMAT_SIZE_T is designed to select the correct format for the OS
4604 ``printf`` function, whereas PyString_FromFormat has an independent
4605 implementation and uses "%zd" on all platforms for size_t values.
4606 This makes a difference on win64, where ``printf`` needs "%Id" to display
4607 64bit values.
4608
Benjamin Peterson97179b02008-09-09 20:55:01 +00004609- Issue #3634: _weakref.ref(Exception).__init__() gave invalid return value on

Amaury Forgeot d'Arcd3ffb892008-09-09 07:24:30 +00004612- Issue #3777: long() applied to a float object now always return a long
4613 object; previously an int would be returned for small values. the __long__
4614 method is allowed to return either an int or a long, but the behaviour of
4615 float objects should not change to respect backward compatibility.
4616
Amaury Forgeot d'Arc3571fbf2008-09-01 19:52:00 +00004617- Issue #3751: str.rpartition would perform a left-partition when called with
4618 a unicode argument.

Vinay Sajip35e3b032008-09-01 14:33:59 +00004623 PyArg_ParseTuple and friends, which occurred when the argument for "s*"
Antoine Pitroud4ae97b2008-08-29 18:39:48 +00004624 was correctly parsed but parsing of subsequent arguments failed.
4625
Vinay Sajip35e3b032008-09-01 14:33:59 +00004626- Issue #2534: speed up isinstance() and issubclass() by 50-70%, so as to
Antoine Pitrou0668c622008-08-26 22:42:08 +00004627 match Python 2.5 speed despite the __instancecheck__ / __subclasscheck__
4628 mechanism. In the process, fix a bug where isinstance() and issubclass(),
4629 when given a tuple of classes as second argument, were looking up
4630 __instancecheck__ / __subclasscheck__ on the tuple rather than on each
4631 type object.
4632
Neal Norwitz18aa3882008-08-24 05:04:52 +00004633- Fix crashes on memory allocation failure found with failmalloc.

Brett Cannon1eaf0742008-09-02 01:25:16 +00004702 warnings.catch_warnings() along with some API cleanup. Expanding the tests

4776-----------------
4777
Guido van Rossumf8402962008-08-20 15:01:50 +00004778- Issue #1878: Remove Py_TPFLAGS_HAVE_VERSION_TAG from
4779 Py_TPFLAGS_DEFAULT when not building the core. This means 3rd party
4780 extensions do not automatically benefit from the class attribute
4781 cache; they will have to explicitly add Py_TPFLAGS_HAVE_VERSION_TAG
4782 to their tp_flags field if they care. This is a backwards
4783 compatibility feature; in 3.0, all types will use the cache by
4784 default.
4785
Benjamin Petersonf647dc12008-08-20 01:27:30 +00004786- Keyword arguments can now follow starred arguments. (``f(a, *args,
4787 keyword=23)`` is now valid syntax.)
4788
Thomas Heller0ad5ae02008-08-19 19:25:04 +00004789- ctypes function pointers that are COM methods have a boolean True
4790 value again.

4794 and introducing s*.
4795
Georg Brandl1e13ea92008-08-11 09:07:59 +00004796- Issue #3537: Fix an assertion failure when an empty but presized dict
4797 object was stored in the freelist.
4798
Mark Dickinsonb6467572008-08-04 21:30:09 +00004799- Issue #1481296: Make long(float('nan')) and int(float('nan')) raise
4800 ValueError consistently across platforms.
4801
Amaury Forgeot d'Arc39fd6722008-07-31 21:28:03 +00004802- Issue #3479: On platforms where sizeof(int) is smaller than sizeof(long)
4803 (64bit Unix, for example), unichr() would truncate its argument and return
4804 u'\x00' for unichr(2**32). Now it properly raises an OverflowError.

Neal Norwitze7d8be82008-07-31 17:17:14 +00004806- Apply security patches from Apple.
4807
Amaury Forgeot d'Arc246daed2008-07-31 00:42:16 +00004808- Issue #2542: Now that issubclass() may call arbitrary code, ensure that

4810
Antoine Pitrou92f82162008-07-25 22:22:08 +00004811- Issue #1819: function calls with several named parameters are now on
4812 average 35% faster (as measured by pybench).
4813
Amaury Forgeot d'Arce4921fe2008-07-21 22:00:38 +00004814- Issue #2378: An unexpected UnboundLocalError or NameError could appear when
4815 the python debugger steps into a class statement: the free variables (local
4816 variables defined in an outer scope) would be deleted from the outer scope.
4817
Gregory P. Smith0470bab2008-07-22 04:46:32 +00004818- Issue #2620: Overflow checking when allocating or reallocating memory
4819 was not always being done properly in some python types and extension
4820 modules. PyMem_MALLOC, PyMem_REALLOC, PyMem_NEW and PyMem_RESIZE have
4821 all been updated to perform better checks and places in the code that
4822 would previously leak memory on the error path when such an allocation
4823 failed have been fixed.

Benjamin Petersone977ad42008-08-20 01:42:01 +00004830- The methods ``is_in_tuple()``, ``is_vararg()``, and ``is_keywordarg()`` of
4831 symtable.Symbol have been deprecated for removal in 3.0 and the next release.
4832
Amaury Forgeot d'Arc351ffb82008-08-18 19:23:47 +00004833- Issue #2234: distutils failed for some versions of the cygwin compiler. The
4834 version reported by these tools does not necessarily follow the python
4835 version numbering scheme, so the module is less strict when parsing it.
4836
Nick Coghlanf70385a2008-08-18 12:42:46 +00004837- Issue #2235: Added Py3k warnings for types which will become unhashable
4838 under the stricter __hash__ inheritance rules in 3.0. Several types
4839 which did not meet the rules for hash invariants and were already
4840 unhashable in 3.0 have now been explicitly flagged as unhashable in
4841 2.6 as well (collections.Mapping, collections.Set, unittest.TestSuite,
4842 xml.dom.minidom.NamedNodeMap, numbers.Number, UserList.UserList)
4843
Brett Cannon88f801d2008-08-18 00:46:22 +00004844- Update __all__ for cookielib, csv, os, urllib2, and weakref to include things
4845 imported into the module but exposed as part of the module's API.
4846
Brett Cannon7b96f072008-08-18 00:41:11 +00004847- Remove an unneeded import of abc.ABCMeta from 'inspect'.
4848

4850
Brett Cannon25c9d6a2008-08-17 22:10:11 +00004851- Remove unneeded imports of 'warnings' from shelve, filecmp, and dummy_thread.
4852
Hirokazu Yamamoto41a81eb2008-08-17 13:10:46 +00004853- Issue #3575: Incremental decoder's decode function now takes bytearray
4854 by using 's*' instead of 't#'.
4855
Mark Dickinson3e4caeb2009-02-21 20:27:01 +00004856- Issue #2222: Fixed reference leak when occurred os.rename()
Hirokazu Yamamoto7f30a682008-08-17 09:46:56 +00004857 fails unicode conversion on 2nd parameter. (windows only)
4858
Georg Brandl222e2082010-08-01 22:27:39 +00004859- Issue #2464: urllib2 now supports a malformation in the URL received
Facundo Batista94f243a2008-08-17 03:38:39 +00004860 in a redirect.
4861
Brett Cannonabe423e2008-08-16 21:47:07 +00004862- Silence the DeprecationWarning raised when importing mimetools in
Brett Cannon721b1452008-08-16 22:00:27 +00004863 BaseHTTPServer, cgi (and rfc822), httplib.
Brett Cannonabe423e2008-08-16 21:47:07 +00004864
Facundo Batistaeb90b782008-08-16 14:44:07 +00004865- Issue #2776: fixed small issue when handling an URL with double slash
4866 after a 302 response in the case of not going through a proxy.
4867
Antoine Pitroub90a8be2008-08-15 21:03:21 +00004868- Issue #2676: in the email package, content-type parsing was hanging on
4869 pathological input because of quadratic or exponential behaviour of a
4870 regular expression.
4871
Antoine Pitrou11ec65d2008-08-14 21:04:30 +00004872- Issue #3476: binary buffered reading through the new "io" library is now
4873 thread-safe.
4874
Brett Cannonbf3157b2008-08-14 05:00:03 +00004875- Silence the DeprecationWarning of rfc822 when it is imported by mimetools
4876 since mimetools itself is deprecated. Because modules are cached, all
4877 subsequent imports of rfc822 will not raise a visible DeprecationWarning.
4878
Antoine Pitrou9fcd4b32008-08-11 17:21:36 +00004879- Issue #3134: shutil referenced undefined WindowsError symbol.

4882 menu entries were not deleted.
4883
Brett Cannon83e81842008-08-09 23:30:55 +00004884- Copied the implementation of reduce() to _functools.reduce() to have a
4885 version that did not raise a DeprecationWarning under -3.
4886
Antoine Pitrou76b8bee2008-08-09 17:27:23 +00004887- Issue #3205: When iterating over a BZ2File fails allocating memory, raise
4888 a MemoryError rather than silently stop the iteration.
4889
Guido van Rossum59ce9012008-08-09 14:55:34 +00004890- Issue #3487: sre "bytecode" validator. Passing invalid "re-bytecode"
4891 to _sre.compile() will now be rejected. This should not affect anybody
4892 since the re.compile() function never generates invalid re-bytecode.
4893
Skip Montanaroa032bf42008-08-08 22:52:51 +00004894- Issue #3436: Make csv.DictReader's fieldnames attribute a property so that
4895 upon first access it can be automatically initialized from the csv file if
4896 it wasn't initialized during instantiation.
4897
Brett Cannon3aa2a492008-08-06 22:28:09 +00004898- Issue #2338: Create imp.reload() to help with transitioning to Python 3.0 as
4899 the reload() built-in has been removed.
4900
Brett Cannon7e30b672008-08-04 21:52:25 +00004901- Changed code in the following modules/packages to remove warnings raised
Brett Cannonc1b76e42008-08-09 23:06:16 +00004902 while running under the ``-3`` flag: aifc, asynchat, asyncore, bdb, bsddb,

4910 raised an AttributeError.
4911
Benjamin Peterson01a24322008-07-28 23:35:27 +00004912- Issue #2523: Fix quadratic behaviour when read()ing a binary file without
Antoine Pitroude781a42008-08-09 12:43:23 +00004913 asking for a specific length. This problem only affected files opened
4914 using the new "io" module, not the built-in open() function.
Benjamin Peterson01a24322008-07-28 23:35:27 +00004915

Antoine Pitrou5fdfa3e2008-07-25 19:42:26 +00004939- Issue #3394: zipfile.writestr sets external attributes when passed a
4940 file name rather than a ZipInfo instance, so files are extracted with
4941 mode 0600 rather than 000 under Unix.
4942
Gregory P. Smitha36f8fe2008-08-04 00:13:29 +00004943- Issue #1857: subprocess.Popen.poll gained an additional _deadstate keyword

4956 interaction with the tp_hash slot (added in 2.6b2) are now documented
4957
Nick Coghlan2a0c2b12008-08-04 12:47:17 +00004958- Issue #643841: The language reference now provides more detailed
4959 coverage of the lookup process for special methods. The disclaimers
4960 regarding lack of coverage of new-style classes have also been
4961 removed, since the coverage is now fairly reasonable.

Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00004967*Release date: 17-Jul-2008*
4968
Raymond Hettingere3ae6552008-06-20 04:18:15 +00004969Core and Builtins
4970-----------------
4971
Georg Brandl3e483f62008-07-16 22:57:41 +00004972- Issue #3156: Fix inconsistent behavior of the bytearray type: all
4973 its methods now allow for items objects that can be converted to
4974 an integer using operator.index().
4975
Mark Dickinson64b7e502008-07-16 09:40:03 +00004976- Issue #3360: Fix incorrect parsing of '020000000000.0', which
4977 produced a ValueError instead of giving the correct float.
4978
Eric Smitha5fa5a22008-07-16 00:11:49 +00004979- Issue #3083: Add alternate (#) formatting for bin, oct, hex output
4980 for str.format(). This adds the prefix 0b, 0o, or 0x, respectively.
4981
Mark Dickinson7103aa42008-07-15 19:08:33 +00004982- Issue #3008: the float type has a new instance method 'float.hex'
4983 and a new class method 'float.fromhex' to convert floating-point
4984 numbers to and from hexadecimal strings, respectively.
4985
Nick Coghlan6d6bd442008-07-15 15:40:22 +00004986- Issue #2235: __hash__ is once again inherited by default. To allow
4987 collections.Hashable to remain meaningful in the presence of the
4988 default hash implementation (object.__hash__), it is now possible
4989 to explicit block inheritance of hash by setting __hash__=None at
4990 the Python level, or tp_hash=PyObject_HashNotImplemented at the C
4991 level.
4992
Nick Coghlanb028f502008-07-13 14:52:36 +00004993- Issue #3221: Issue a RuntimeWarning instead of raising SystemError if
4994 the parent module cannot be found while performing an absolute import.
4995 This means that an incorrectly defined __package__ attribute will
4996 now only prevent relative imports in that module rather than causing
4997 all imports from that module to fail.
4998
Nick Coghlan14ff9942008-07-08 14:21:42 +00004999- Issue #2517: Allow unicode messages in Exceptions again by correctly
5000 bypassing the instance dictionary when looking up __unicode__ on
5001 new-style classes.
5002
Amaury Forgeot d'Arcbdd941f2008-07-01 20:38:04 +00005003- Issue #3242: Fix a crash inside the print statement, if sys.stdout is
5004 set to a custom object whose write() method happens to install
5005 another file in sys.stdout.
5006
Amaury Forgeot d'Arc1f40c8a2008-06-30 22:42:40 +00005007- Issue #3088: Corrected a race condition in classes derived from
5008 threading.local: the first member set by a thread could be saved in
5009 another thread's dictionary.
5010
Mark Dickinson1ec2fcd2008-06-20 14:53:43 +00005011- Issue #3004: Minor change to slice.indices(): the start and stop
5012 arguments are now treated identically, making the behaviour easier
5013 to describe and understand. For example, slice(None, -10,
5014 1).indices(9) now returns (0, 0, 1) instead of (0, -1, 1), and
5015 slice(None, 10, -1).indices(10) returns (9, 9, -1) instead of (9,
5016 10, -1).
5017
Georg Brandl278fc502008-07-19 12:46:12 +00005018- Issue #3219: Calling a function with repeated keyword arguments,
5019 f(a=2, a=23), would not cause a syntax error. This was a regression
5020 from 2.4 caused by the switch to the new compiler.
Benjamin Peterson175e4d92008-07-01 19:34:52 +00005021
Georg Brandl278fc502008-07-19 12:46:12 +00005022- Issue #2862: Make int and float freelist management consistent with
5023 other freelists. Changes their CompactFreeList apis into
5024 ClearFreeList apis and calls them via gc.collect().

Thomas Heller57adf222008-08-14 19:10:48 +00005029- Issue #3554: ctypes.string_at and ctypes.wstring_at did call Python
5030 api functions without holding the GIL, which could lead to a fatal
5031 error when they failed.
5032
Martin v. Löwisaabf4042008-08-02 07:20:25 +00005033- Issue #799428: Fix Tkinter.Misc._nametowidget to unwrap Tcl command objects.

Amaury Forgeot d'Arc0f7cddc2008-07-06 21:34:39 +00005058- Issue #839496: SimpleHTTPServer used to open text files in text mode. This is
5059 both unnecessary (HTTP allows text content to be sent in several forms) and
Andrew M. Kuchlingcc3f2b12008-07-10 14:43:31 +00005060 wrong because the actual transmitted size could differ from the
Amaury Forgeot d'Arc0f7cddc2008-07-06 21:34:39 +00005061 content-length. The problem had been corrected in the 2.4 branch, but never
5062 merged into trunk.

Nick Coghlanc060b0e2008-07-02 13:09:19 +00005077- Issue #3190: Pydoc now hides the automatic module attribute __package__ (the

5079
Brett Cannon8bb8fa52008-07-02 01:57:08 +00005080- Issue #2885 (partial): The urllib.urlopen() function has been deprecated for

5469 mode or even as a 4-way universal binary (that is, PPC, i386,
Georg Brandl5cc774e2008-06-11 20:28:06 +00005470 PPC64 and x86_64 support in one binary).
Ronald Oussoren5640ce22008-06-05 12:58:24 +00005471
5472 This is controlled by the configure argument ``--with-universal-archs``:
5473
5474 - ``--with-universal-archs=all``: install 4-way universal
5475
5476 - ``--with-universal-archs=32-bit``: install 2-way universal, 32-bit (the default)
5477
5478 - ``--with-universal-archs=64-bit``: install 2-way universal, 64-bit
5479
5480 This option should be used in combination with ``--enable-universalsdk=``.
5481
5482 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 +00005532- Issue #1631171: Re-implement the 'warnings' module in C (the
5533 original Python code has been kept as backup). This will allow for
5534 using the 'warning's machinery in such places as the parser where
5535 use of pure Python code is not possible. Both the ``showarning()``
5536 and ``formatwarning()`` gain an optional 'line' argument which is
5537 not called by default for backwards-compatibility reasons. Setting
5538 ``warnings.showwarning()`` to an implementation that lacks support
5539 for the ``line`` argument will raise a DeprecationWarning.

Georg Brandl3ee81df2008-05-17 18:14:43 +00005602- Issue #2550: The approach used by client/server code for obtaining
5603 ports to listen on in network-oriented tests has been refined in an
5604 effort to facilitate running multiple instances of the entire
5605 regression test suite in parallel without issue.
5606 test_support.bind_port() has been fixed such that it will always
5607 return a unique port -- which wasn't always the case with the
5608 previous implementation, especially if socket options had been set
5609 that affected address reuse (i.e. SO_REUSEADDR, SO_REUSEPORT). The
5610 new implementation of bind_port() will actually raise an exception
5611 if it is passed an AF_INET/SOCK_STREAM socket with either the
5612 SO_REUSEADDR or SO_REUSEPORT socket option set. Furthermore, if
5613 available, bind_port() will set the SO_EXCLUSIVEADDRUSE option on
5614 the socket it's been passed. This currently only applies to
5615 Windows. This option prevents any other sockets from binding to the
5616 host/port we've bound to, thus removing the possibility of the
5617 'non-deterministic' behaviour, as Microsoft puts it, that occurs
5618 when a second SOCK_STREAM socket binds and accepts to a host/port
5619 that's already been bound by another socket. The optional preferred
5620 port parameter to bind_port() has been removed. Under no
5621 circumstances should tests be hard coding ports!
5622
5623 test_support.find_unused_port() has also been introduced, which will
5624 pass a temporary socket object to bind_port() in order to obtain an
5625 unused port. The temporary socket object is then closed and
5626 deleted, and the port is returned. This method should only be used
5627 for obtaining an unused port in order to pass to an external program
5628 (i.e. the -accept [port] argument to openssl's s_server mode) or as
5629 a parameter to a server-oriented class that doesn't give you direct
5630 access to the underlying socket used.
5631
5632 Finally, test_support.HOST has been introduced, which should be used
5633 for the host argument of any relevant socket calls (i.e. bind and
5634 connect).
Trent Nelsone41b0062008-04-08 23:47:30 +00005635
5636 The following tests were updated to following the new conventions:
Georg Brandl3ee81df2008-05-17 18:14:43 +00005637 test_socket, test_smtplib, test_asyncore, test_ssl, test_httplib,
Trent Nelsone41b0062008-04-08 23:47:30 +00005638 test_poplib, test_ftplib, test_telnetlib, test_socketserver,
5639 test_asynchat and test_socket_ssl.
5640
Georg Brandl3ee81df2008-05-17 18:14:43 +00005641 It is now possible for multiple instances of the regression test
5642 suite to run in parallel without issue.

Christian Heimes5224d282008-02-23 15:01:05 +00005917
Vinay Sajipb7edfc42008-04-02 21:10:23 +00005918- Issue #1881: An internal parser limit has been increased. Also see
Georg Brandl222e2082010-08-01 22:27:39 +00005919 issue #215555 for a discussion.
Facundo Batistafc2d0102008-02-23 12:01:13 +00005920
Eric Smitha73fbe72008-02-23 03:09:44 +00005921- Added the future_builtins module, which contains hex() and oct().
5922 These are the PEP 3127 version of these functions, designed to be
5923 compatible with the hex() and oct() builtins from Python 3.0. They
5924 differ slightly in their output formats from the existing, unchanged
5925 Python 2.6 builtins. The expected usage of the future_builtins
5926 module is:
5927 from future_builtins import hex, oct
5928
Eric Smith7ef40bf2008-02-20 23:34:22 +00005929- Issue #1600: Modifed PyOS_ascii_formatd to use at most 2 digit
5930 exponents for exponents with absolute value < 100. Follows C99
5931 standard. This is a change on Windows, which would use 3 digits.
5932 Also, added 'n' to the formats that PyOS_ascii_formatd understands,
5933 so that any alterations it does to the resulting string will be
5934 available in stringlib/formatter.h (for float.__format__).
5935
Eric Smith5a3c1352008-02-19 13:21:56 +00005936- Implemented PEP 3101, Advanced String Formatting. This adds a new
5937 builtin format(); a format() method for str and unicode; a
5938 __format__() method to object, str, unicode, int, long, float, and
5939 datetime; the class string.Formatter; and the C API
5940 PyObject_Format().
5941
Georg Brandl3ee81df2008-05-17 18:14:43 +00005942- Fixed several potential crashes, all caused by specially crafted
5943 __del__ methods exploiting objects in temporarily inconsistent
5944 state.
Amaury Forgeot d'Arc632fad32008-02-16 20:55:24 +00005945
Vinay Sajipb7edfc42008-04-02 21:10:23 +00005946- Issue #2115: Important speedup in setting __slot__ attributes. Also
Georg Brandl3ee81df2008-05-17 18:14:43 +00005947 prevent a possible crash: an Abstract Base Class would try to access
5948 a slot on a registered virtual subclass.
Amaury Forgeot d'Arc60d6c7f2008-02-15 21:22:45 +00005949
Georg Brandl3ee81df2008-05-17 18:14:43 +00005950- Fixed repr() and str() of complex numbers with infinity or nan as
5951 real or imaginary part.
Christian Heimes2f0da532008-02-15 06:57:08 +00005952
Georg Brandl3ee81df2008-05-17 18:14:43 +00005953- Clear all free lists during a gc.collect() of the highest generation
5954 in order to allow pymalloc to free more arenas. Python may give back
5955 memory to the OS earlier.
Christian Heimes3b718a72008-02-14 12:47:33 +00005956
Georg Brandl3ee81df2008-05-17 18:14:43 +00005957- Issue #2045: Fix an infinite recursion triggered when printing a
5958 subclass of collections.defaultdict, if its default_factory is set
5959 to a bound method.
Amaury Forgeot d'Arcb01aa432008-02-08 00:56:02 +00005960
Christian Heimesf75dbef2008-02-08 00:11:31 +00005961- Fixed a minor memory leak in dictobject.c. The content of the free
5962 list was not freed on interpreter shutdown.
5963
Georg Brandl21e99f42010-03-07 15:23:59 +00005964- Limit free list of method and built-in function objects to 256
Georg Brandl3ee81df2008-05-17 18:14:43 +00005965 entries each.
Christian Heimes6075a822008-02-06 12:44:34 +00005966
Georg Brandl3ee81df2008-05-17 18:14:43 +00005967- Patch #1953: Added ``sys._compact_freelists()`` and the C API
5968 functions ``PyInt_CompactFreeList`` and ``PyFloat_CompactFreeList``
Christian Heimes422051a2008-02-04 18:00:12 +00005969 to compact the internal free lists of pre-allocted ints and floats.
5970
Georg Brandl3ee81df2008-05-17 18:14:43 +00005971- Issue #1983: Fixed return type of fork(), fork1() and forkpty()
5972 calls. Python expected the return type int but the fork familie
5973 returns pi_t.
Christian Heimes951cc0f2008-01-31 23:08:23 +00005974
Georg Brandl3ee81df2008-05-17 18:14:43 +00005975- Issue #1678380: Fix a bug that identifies 0j and -0j when they
5976 appear in the same code unit.
Mark Dickinson105be772008-01-31 22:17:37 +00005977
Georg Brandl3ee81df2008-05-17 18:14:43 +00005978- Issue #2025: Add tuple.count() and tuple.index() methods to comply
5979 with the collections.Sequence API.
Raymond Hettinger5b07ebc2008-02-07 00:54:20 +00005980
Georg Brandl3ee81df2008-05-17 18:14:43 +00005981- Patch #1970 by Antoine Pitrou: Speedup unicode whitespace and
5982 linebreak detection
Christian Heimes4d4f2702008-01-30 11:32:37 +00005983
Georg Brandl3ee81df2008-05-17 18:14:43 +00005984- Added ``PyType_ClearCache()`` and ``sys._clear_type_cache`` to clear
5985 the internal lookup cache for ref leak tests.
Christian Heimes908caac2008-01-27 23:34:59 +00005986
Georg Brandl3ee81df2008-05-17 18:14:43 +00005987- Patch #1473257: generator objects gain a gi_code attribute. This is
5988 the same object as the func_code attribute of the function that
5989 produced the generator.
Georg Brandl0cdf9a32008-01-26 14:14:20 +00005990
Georg Brandl3ee81df2008-05-17 18:14:43 +00005991- Issue #1920: "while 0" statements were completely removed by the
5992 compiler, even in the presence of an "else" clause, which is
5993 supposed to be run when the condition is false. Now the compiler
5994 correctly emits bytecode for the "else" suite.
Amaury Forgeot d'Arc31eaafe2008-01-24 22:59:25 +00005995
Guido van Rossumeead05f2008-01-24 18:21:02 +00005996- A few crashers fixed: weakref_in_del.py (issue #1377858);
5997 loosing_dict_ref.py (issue #1303614, test67.py);
5998 borrowed_ref_[34].py (not in tracker).
5999
Vinay Sajipd7cf32e2008-01-24 12:43:33 +00006000- Issue #1069410: The "can't load dll" message box on Windows is
Christian Heimesb2302ba2008-01-23 17:15:06 +00006001 suppressed while an extension is loaded by calling SetErrorMode in
6002 dynload_win.c. The error is still reported properly.
6003
Georg Brandl3ee81df2008-05-17 18:14:43 +00006004- Issue #1915: Python compiles with --enable-unicode=no again. However
Christian Heimes082c9b02008-01-23 14:20:50 +00006005 several extension methods and modules do not work without unicode
6006 support.
6007
Georg Brandl26543b12008-01-21 18:36:51 +00006008- Issue #1882: when compiling code from a string, encoding cookies in the
6009 second line of code were not always recognized correctly.
6010
Georg Brandl14404b62008-01-19 19:27:05 +00006011- Issue #1679: "0x" was taken as a valid integer literal.
6012
Georg Brandl6caad7d2008-01-26 14:19:22 +00006013- Issue #1865: ``bytes`` as an alias for ``str`` and b"" as an alias "" were
Christian Heimes288e89a2008-01-18 18:24:07 +00006014 added.
6015
Christian Heimesc94e2b52008-01-14 04:13:37 +00006016- sys.float_info / PyFloat_GetInfo: The floating point information
6017 object was converted from a dict to a specialized structseq object.
6018
Georg Brandl3ee81df2008-05-17 18:14:43 +00006019- Patch #1816: Added sys.flags structseq. It exposes the status of
6020 most command line arguments and PYTHON* environment variables.
Christian Heimesf31b69f2008-01-14 03:42:48 +00006021
Georg Brandl3ee81df2008-05-17 18:14:43 +00006022- Objects/structseq.c: Implemented new structseq representation. The
6023 patch makes structseqs (e.g. the return value of os.stat) more
6024 readable.
Christian Heimes9c201962008-01-14 03:33:52 +00006025
Georg Brandl3ee81df2008-05-17 18:14:43 +00006026- Patch #1700288: added a type attribute cache that caches method
6027 accesses, resulting in speedups in heavily object-oriented code.
Amaury Forgeot d'Arce4c270c2008-01-14 00:29:41 +00006028
Neal Norwitz3fc15b82008-01-10 05:42:58 +00006029- Bug #1776: __import__() no longer accepts filenames on any platform.
6030 The first parameter to __import__() must be a valid module name.
Christian Heimes3403f152008-01-09 19:56:33 +00006031

6033
Georg Brandl3ee81df2008-05-17 18:14:43 +00006034- Patch #602345: Add -B command line option, PYTHONDONTWRITEBYTECODE
6035 envvar and sys.dont_write_bytecode attribute. All these can be set
6036 to forbid Python to attempt to write compiled bytecode files.
Georg Brandl2da0fce2008-01-07 17:09:35 +00006037
Georg Brandl3ee81df2008-05-17 18:14:43 +00006038- Improve some exception messages when Windows fails to load an
6039 extension module. Now we get for example '%1 is not a valid Win32
6040 application' instead of 'error code 193'.
Amaury Forgeot d'Arce0b76952008-01-04 02:04:15 +00006041
Georg Brandl3ee81df2008-05-17 18:14:43 +00006042- Bug #1481296: Fixed long(float('nan')) != 0L.

Georg Brandl3ee81df2008-05-17 18:14:43 +00006044- Issue #1640: Added math.isinf(x), math.isnan(x) and math.copysign(x,
6045 y) functions.
Christian Heimese2ca4242008-01-03 20:23:15 +00006046
Christian Heimes0a8143f2007-12-18 23:22:54 +00006047- Issue #1635: Platform independent creation and representation of NaN
Georg Brandl3ee81df2008-05-17 18:14:43 +00006048 and INF. float("nan"), float("inf") and float("-inf") now work on
6049 every platform with IEEE 754 semantics.
Christian Heimes0a8143f2007-12-18 23:22:54 +00006050
Georg Brandl3ee81df2008-05-17 18:14:43 +00006051- Compiler now generates simpler and faster code for dictionary
6052 literals. The oparg for BUILD_MAP now indicates an estimated
6053 dictionary size. There is a new opcode, STORE_MAP, for adding
6054 entries to the dictionary.
Raymond Hettingerfd7ed402007-12-18 21:24:09 +00006055
Georg Brandl3ee81df2008-05-17 18:14:43 +00006056- Issue #1638: %zd configure test fails on Linux.

6069 __package__ attribute.
6070
Georg Brandl3ee81df2008-05-17 18:14:43 +00006071- Issue #1402: Fix a crash on exit, when another thread is still
6072 running, and if the deallocation of its frames somehow calls the
6073 PyGILState_Ensure() / PyGILState_Release() functions.
Amaury Forgeot d'Arcbe49a902007-11-30 20:37:22 +00006074

6084 file can now be directly executed by passing their name to the
6085 interpreter. The directory/zipfile is automatically inserted as the
6086 first entry in sys.path.
Nick Coghlan327a39b2007-11-18 11:56:28 +00006087
Georg Brandl3ee81df2008-05-17 18:14:43 +00006088- Issue #1265: Fix a problem with sys.settrace, if the tracing
6089 function uses a generator expression when at the same time the
6090 executed code is closing a paused generator.
Amaury Forgeot d'Arc0d75f092007-11-13 21:54:28 +00006091
Raymond Hettinger1760c8a2007-11-08 02:52:43 +00006092- sets and frozensets now have an isdisjoint() method.
6093
Raymond Hettinger3f8caa32007-10-24 01:28:33 +00006094- optimize the performance of builtin.sum().

Neal Norwitz44f326e2007-10-05 05:29:17 +00006096- Fix warnings found by the new version of the Coverity checker.
6097
Georg Brandl21e99f42010-03-07 15:23:59 +00006098- The enumerate() built-in function is no longer bounded to sequences
Georg Brandl3ee81df2008-05-17 18:14:43 +00006099 smaller than LONG_MAX. Formerly, it raised an OverflowError. Now,
6100 automatically shifts from ints to longs.
Raymond Hettinger8f669372007-10-03 21:18:11 +00006101
Georg Brandl3ee81df2008-05-17 18:14:43 +00006102- Issue #1686386: Tuple's tp_repr did not take into account the
6103 possibility of having a self-referential tuple, which is possible
6104 from C code. Nor did object's tp_str consider that a type's tp_str
6105 could do something that could lead to an inifinite recursion.
6106 Py_ReprEnter() and Py_EnterRecursiveCall(), respectively, fixed the
6107 issues.
Brett Cannon0b14f242007-09-30 19:45:10 +00006108
Georg Brandl3ee81df2008-05-17 18:14:43 +00006109- Issue #1164: It was possible to trigger deadlock when using the
6110 'print' statement to write to a file since the GIL was not released
6111 as needed. Now PyObject_Print() does the right thing along with
6112 various tp_print implementations of the built-in types and those in
6113 the collections module.
Brett Cannon01531592007-09-17 03:28:34 +00006114
Georg Brandl3ee81df2008-05-17 18:14:43 +00006115- Issue #1147: Exceptions were directly allowing string exceptions in
6116 their throw() method even though string exceptions no longer
6117 allowed.
Brett Cannon4c20bc42007-09-11 21:02:28 +00006118

Brett Cannon1e534b52007-09-07 04:18:30 +00006122- Issue #1202533: Fix infinite recursion calls triggered by calls to
Georg Brandl3ee81df2008-05-17 18:14:43 +00006123 PyObject_Call() never calling back out to Python code to trigger
6124 recursion depth updates/checks. Required the creation of a static
6125 RuntimeError instance in case normalizing an exception put the
6126 recursion check value past its limit. Fixes crashers
6127 infinite_rec_(1|2|4|5).py.
Brett Cannon1e534b52007-09-07 04:18:30 +00006128

Neal Norwitz0ac60192007-05-27 04:08:54 +00006142- Add new attribute names for function objects. All the func_* become
Georg Brandl3ee81df2008-05-17 18:14:43 +00006143 __*__ attributes. (Some already existed, e.g., __doc__ and
6144 __name__.)
Neal Norwitz0ac60192007-05-27 04:08:54 +00006145
Neal Norwitz8b2bfbc2007-05-23 06:35:32 +00006146- Add -3 option to the interpreter to warn about features that are
6147 deprecated and will be changed/removed in Python 3.0.
6148
Georg Brandl2134e752007-05-21 20:34:16 +00006149- Patch #1686487: you can now pass any mapping after '**' in function
6150 calls.
6151
Collin Winter62903052007-05-18 23:11:24 +00006152- except clauses may now be spelled either "except E, target:" or
Georg Brandl3ee81df2008-05-17 18:14:43 +00006153 "except E as target:". This is to provide forwards compatibility
6154 with Python 3.0.

Vinay Sajip8549ce32007-05-06 17:53:37 +00006161- When __slots__ are set to a unicode string, make it work the same as
Neal Norwitzcbd9ee62007-04-14 05:25:50 +00006162 setting a plain string, ie don't expand to single letter identifiers.

6168 remaining characters.
6169
Georg Brandl5cb76c12007-03-21 09:00:39 +00006170- Patch #1682205: a TypeError while unpacking an iterable is no longer

Guido van Rossum143b5642007-03-23 04:58:42 +00006175- Bug #1683368: The object.__init__() and object.__new__() methods are
6176 now stricter in rejecting excess arguments. The only time when
6177 either allows excess arguments is when it is not overridden and the
6178 other one is. For backwards compatibility, when both are
6179 overridden, it is a deprecation warning (for now; maybe a Py3k
Guido van Rossum234b1ff2007-03-23 19:39:01 +00006180 warning later). Also, type.__init__() insists on the same signature
6181 as supported by type.__new__().

Georg Brandl3ee81df2008-05-17 18:14:43 +00006183- Patch #1675423: PyComplex_AsCComplex() now tries to convert an
6184 object to complex using its __complex__() method before falling back
6185 to the __float__() method. Therefore, the functions in the cmath
6186 module now can operate on objects that define a __complex__()
6187 method.

Georg Brandl7b9c5552007-03-12 14:30:05 +00006205- Bug #1678647: write a newline after printing an exception in any
6206 case, even when converting the value to a string failed.
6207
Georg Brandl871f1bc2007-03-12 13:17:36 +00006208- The dir() function has been extended to call the __dir__() method on
Georg Brandl3ee81df2008-05-17 18:14:43 +00006209 its argument, if it exists. If not, it will work like before. This
6210 allows customizing the output of dir() in the presence of a
6211 __getattr__().

6221 raising a ValueError.

Georg Brandlaa2321b2007-03-07 00:40:28 +00006223- Patch #703779: unset __file__ in __main__ after running a file. This
Georg Brandl3ee81df2008-05-17 18:14:43 +00006224 makes the filenames the warning module prints much more sensible
6225 when a PYTHONSTARTUP file is used.

6239 sq_ass_slice instead of the sq_slice slot.
6240
Georg Brandl3ee81df2008-05-17 18:14:43 +00006241- When printing an unraisable error, don't print exceptions. before

6294 embedded in the string to convert.
6295
Georg Brandl846f73a2006-10-08 07:11:54 +00006296- Bug #1569998: break inside a try statement (outside a loop) is now

Georg Brandl3ee81df2008-05-17 18:14:43 +00006344 generator expressions (x for x, in ... ) works again. Fixing this
6345 problem required changing the .pyc magic number. This means that
6346 .pyc files generated before 2.5c2 will be regenerated.

Georg Brandl3ee81df2008-05-17 18:14:43 +00007153- Issue #829951: In the smtplib module, SMTP.starttls() now complies
7154 with RFC 3207 and forgets any knowledge obtained from the server not
7155 obtained from the TLS negotiation itself. Patch contributed by Bill
7156 Fenner.
Gregory P. Smith2b3ba582008-01-17 08:03:17 +00007157
Georg Brandl3ee81df2008-05-17 18:14:43 +00007158- Issue #1339: The smtplib.SMTP class has been refactored a bit such
Gregory P. Smithbde4ae42008-01-17 08:35:49 +00007159 that the SMTP.starttls() caller no longer needs to call ehlo()
7160 beforehand. SMTP.starttls() now raises an exception of the server
Georg Brandl3ee81df2008-05-17 18:14:43 +00007161 does not claim to support starttls. Adds the
7162 SMTP.ehlo_or_helo_if_needed() method. Patch contributed by Bill
7163 Fenner.

7243 complex, tuple, list, dict, set, and frozenset. Formerly, it would
7244 silently miscode subclasses of those types. Now, it raises a
7245 ValueError instead.
Raymond Hettinger12e94202007-11-07 01:13:09 +00007246

Georg Brandl3ee81df2008-05-17 18:14:43 +00007261 time so that opening a database previously created with the DB_DUP
7262 or DB_DUPSORT flag set will keep the proper behavior on subsequent
7263 opens. Specifically: dictionary assignment to a DB object will
7264 replace all values for a given key when the database allows
7265 duplicate values. DB users should use DB.put(k, v) when they want
7266 to store duplicates; not DB[k] = v.
Gregory P. Smithec10a4a2007-11-05 02:32:26 +00007267

7273 characters with ASCII value less than 32. Also, it correctly quotes
7274 dots only if they occur on a single line, as opposed to the previous
7275 behavior of quoting dots if they are the second character of any
7276 line.
Georg Brandl4aef7272007-03-13 22:49:43 +00007277

Georg Brandl3ee81df2008-05-17 18:14:43 +00007682- Removed the macfs module. It had been deprecated since Python 2.5.
7683 This lead to the deprecation of macostools.touched() as it relied
7684 solely on macfs and was a no-op under OS X.
