Victor Stinner08563d92011-05-30 23:44:13 +02004What's New in Python 2.7.3?
5===========================

7*Release date: XXXX-XX-XX*
8
9Core and Builtins
10-----------------
11
Mark Hammond323b5da2011-10-17 11:05:36 +110012- Issue #7833: Extension modules built using distutils on Windows will no
13 longer include a "manifest" to prevent them failing at import time in some
14 embedded situations.
15
Benjamin Petersona7b09762011-10-15 13:43:21 -040016- Issue #13186: Fix __delitem__ on old-style instances when invoked through
17 PySequence_DelItem.
18
Charles-François Natali40ab0022011-10-12 22:29:09 +020019- Issue #13156: Revert the patch for issue #10517 (reset TLS upon fork()),
20 which was only relevant for the native pthread TLS implementation.
21
Victor Stinner63c22fa2011-09-23 19:37:03 +020022- Issue #7732: Fix a crash on importing a module if a directory has the same
23 name than a Python module (e.g. "__init__.py"): don't close the file twice.
24
Mark Dickinsondbbed042011-09-19 16:38:08 +010025- Issue #12973: Fix overflow checks that invoked undefined behaviour in
26 int.__pow__. These overflow checks were causing int.__pow__ to produce
27 incorrect results with recent versions of Clang, as a result of the
Mark Dickinsona96b0d12011-09-24 09:01:16 +010028 compiler optimizing the check away. Also fix similar overflow checks
29 in list_repeat (listobject.c) and islice_next (itertoolsmodule.c). These
30 bugs caused test failures with recent versions of Clang.
Mark Dickinsondbbed042011-09-19 16:38:08 +010031
Ezio Melotti15d6b652011-08-15 09:22:24 +030032- Issue #12266: Fix str.capitalize() to correctly uppercase/lowercase
33 titlecased and cased non-letter characters.
34
Benjamin Peterson6c18ff02011-07-22 10:41:44 -050035- Issues #12610 and #12609: Verify that user generated AST has correct string
36 and identifier types before compiling.
37
Barry Warsawc5643282011-07-19 17:06:30 -040038- Issue #11627: Fix segfault when __new__ on a exception returns a
39 non-exception class.
Benjamin Petersonc3349cd2011-07-15 14:15:40 -050040
Antoine Pitrou16166452011-07-12 22:04:20 +020041- Issue #12149: Update the method cache after a type's dictionnary gets
42 cleared by the garbage collector. This fixes a segfault when an instance
43 and its type get caught in a reference cycle, and the instance's
44 deallocator calls one of the methods on the type (e.g. when subclassing
45 IOBase). Diagnosis and patch by Davide Rizzo.
46
Victor Stinnerba8b3a22011-07-08 02:07:45 +020047- Issue #12501: Adjust callable() warning: callable() is only not supported in
48 Python 3.1. callable() is again supported in Python 3.2.
49
Victor Stinner59729ff2011-07-05 11:28:19 +020050- Issue #9611, #9015: FileIO.read(), FileIO.readinto(), FileIO.write() and
51 os.write() clamp the length to INT_MAX on Windows.
52
Victor Stinnerd3c7e172011-05-30 23:49:13 +020053- Issue #1195: my_fgets() now always clears errors before calling fgets(). Fix
Victor Stinner08563d92011-05-30 23:44:13 +020054 the following case: sys.stdin.read() stopped with CTRL+d (end of file),
55 raw_input() interrupted by CTRL+c.
56
Łukasz Langa7a153902011-10-18 17:16:00 +020057- Issue #10860: httplib now correctly handles an empty port after port
58 delimiter in URLs.
59
Barry Warsawc5643282011-07-19 17:06:30 -040060- dict_proxy objects now display their contents rather than just the class
61 name.

193
Ned Deily87e82bb2011-06-28 19:52:59 -0700194- Issue #9516: On Mac OS X, change Distutils to no longer globally attempt to
195 check or set the MACOSX_DEPLOYMENT_TARGET environment variable for the
196 interpreter process. This could cause failures in non-Distutils subprocesses
197 and was unreliable since tests or user programs could modify the interpreter
198 environment after Distutils set it. Instead, have Distutils set the the
199 deployment target only in the environment of each build subprocess. It is
200 still possible to globally override the default by setting
201 MACOSX_DEPLOYMENT_TARGET before launching the interpreter; its value must be
202 greater or equal to the default value, the value with which the interpreter
203 was built.
204

212 times without error, and _ProxyFile now closes the wrapped file.
213
Victor Stinnerc74a6ba2011-06-17 14:06:27 +0200214- Issue #12133: AbstractHTTPHandler.do_open() of urllib.request closes the HTTP
215 connection if its getresponse() method fails with a socket error. Patch
216 written by Ezio Melotti.
217
Benjamin Peterson0eb4ac42011-06-11 15:53:11 -0500218- Issue #9284: Allow inspect.findsource() to find the source of doctest
219 functions.
220

222
Brian Curtincaea7e82011-06-08 19:29:53 -0500223- Issue #11583: Speed up os.path.isdir on Windows by using GetFileAttributes

230
Barry Warsawc5643282011-07-19 17:06:30 -0400231- sys.setcheckinterval() now updates the current ticker count as well as
232 updating the check interval, so if the user decreases the check interval,
233 the ticker doesn't have to wind down to zero from the old starting point
234 before the new interval takes effect. And if the user increases the
235 interval, it makes sure the new limit takes effect right away rather have an
236 early task switch before recognizing the new interval.

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

1119
Raymond Hettinger20397532010-09-12 02:11:45 +00001120- Issue #9825: removed __del__ from the definition of collections.OrderedDict.
1121 This prevents user-created self-referencing ordered dictionaries from
1122 becoming permanently uncollectable GC garbage. The downside is that
1123 removing __del__ means that the internal doubly-linked list has to wait for
1124 GC collection rather than freeing memory immediately when the refcnt drops
1125 to zero.

1130
Antoine Pitrouc818ed42010-09-07 21:40:25 +00001131- Issue #9792: In case of connection failure, socket.create_connection()
1132 would swallow the exception and raise a new one, making it impossible
1133 to fetch the original errno, or to filter timeout errors. Now the
1134 original error is re-raised.

1155
R. David Murray7c4bf552010-08-25 01:45:57 +00001156- Issue #1194222: email.utils.parsedate now returns RFC2822 compliant four

Ezio Melottiab2eb0e2010-06-05 19:21:32 +00001584- Issue #8271: during the decoding of an invalid UTF-8 byte sequence, only the
1585 start byte and the continuation byte(s) are now considered invalid, instead
1586 of the number of bytes specified by the start byte.
1587 E.g.: '\xf1\x80AB'.decode('utf-8', 'replace') now returns u'\ufffdAB' and
1588 replaces with U+FFFD only the start byte ('\xf1') and the continuation byte
1589 ('\x80') even if '\xf1' is the start byte of a 4-bytes sequence.

Mark Dickinson4ca7c3c2010-05-30 13:18:10 +00001598- Issue #8748: Fix two issues with comparisons between complex and integer
1599 objects. (1) The comparison could incorrectly return True in some cases
1600 (2**53+1 == complex(2**53) == 2**53), breaking transivity of equality.
1601 (2) The comparison raised an OverflowError for large integers, leading
1602 to unpredictable exceptions when combining integers and complex objects
1603 in sets or dicts.

Mark Dickinson81336372010-05-30 12:12:25 +00001605- Issue #5211: Implicit coercion for the complex type is now completely

Georg Brandlba83f822010-03-14 09:50:54 +00002483 file position when calling `truncate()`. It would previously change the file
2484 position to the given argument, which goes against the tradition of

2488 class used to represent files stored inside an archive. The new
2489 implementation is significantly faster and can be wrapped in a

2491 where interleaved calls to ``read()`` and ``readline()`` give wrong results.

Georg Brandlba83f822010-03-14 09:50:54 +00002582- The ``__complex__()`` method is now looked up on the class of instances to
2583 make it consistent with other special methods.

2587
Mark Dickinson1b34d252010-01-01 17:27:30 +00002588- Issue #5080: A number of functions and methods previously produced a
Georg Brandlba83f822010-03-14 09:50:54 +00002589 DeprecationWarning when passed a float argument where an integer was expected.
2590 These functions and methods now raise TypeError instead. The majority of the
2591 effects of this change are in the extension modules, but some core functions
2592 and methods are affected: notably the 'chr', 'range' and 'xrange' builtins,
2593 and many unicode/str methods.

2608 least on IEEE 754 platforms), and in particular does not depend on the
2609 internal representation of a long.

2617
Georg Brandlba83f822010-03-14 09:50:54 +00002618 These executables now work properly with the arch(1) command: ``arch -ppc

2706 ``PyArg_ParseTupleAndKeywords()``, ``PyArg_VaParse()``,
2707 ``PyArg_VaParseTupleAndKeywords()`` and ``PyArg_Parse()`` no longer accept
2708 float arguments for integer format codes (other than 'L'): previously an
2709 attempt to pass a float resulted in a DeprecationWarning; now it gives a
2710 TypeError. For the 'L' format code (which previously had no warning) there is
2711 now a DeprecationWarning.

2760 to 'g' for large values.
Amaury Forgeot d'Arcd7288712009-12-01 21:51:04 +00002761
Georg Brandlba83f822010-03-14 09:50:54 +00002762- Remove switch from "%f" formatting to "%g" formatting for floats larger than
2763 1e50 in absolute value.

2767 significant digits instead.

Ronald Oussoren315cd0c2009-11-19 16:25:21 +00002775
Georg Brandlba83f822010-03-14 09:50:54 +00002776- Issue #7117: ``repr(x)`` for a float x returns a result based on the shortest
2777 decimal string that's guaranteed to round back to x under correct rounding
2778 (with round-half-to-even rounding mode). Previously it gave a string based on
2779 rounding x to 17 decimal digits. repr(x) for a complex number behaves
2780 similarly. On platforms where the correctly-rounded strtod and dtoa code is
2781 not supported (see below), repr is unchanged.
Mark Dickinsonb678de82009-11-19 18:41:49 +00002782
Georg Brandlba83f822010-03-14 09:50:54 +00002783- Issue #7117: On almost all platforms: float-to-string and string-to-float
2784 conversions within Python are now correctly rounded. Places these conversions
2785 occur include: str for floats and complex numbers; the float and complex
2786 constructors; old-style and new-style numeric formatting; serialization and
2787 deserialization of floats and complex numbers using marshal, pickle and json;
2788 parsing of float and imaginary literals in Python code; Decimal-to-float
2789 conversion.
Mark Dickinsonb678de82009-11-19 18:41:49 +00002790
Georg Brandlba83f822010-03-14 09:50:54 +00002791 The conversions use a Python-adapted version of David Gay's well-known dtoa.c,
2792 providing correctly-rounded strtod and dtoa C functions. This code is
2793 supported on Windows, and on Unix-like platforms using gcc, icc or suncc as
2794 the C compiler. There may be a small number of platforms on which correct
2795 operation of this code cannot be guaranteed, so the code is not used: notably,
2796 this applies to platforms where the C double format is not IEEE 754 binary64,
2797 and to platforms on x86 hardware where the x87 FPU is set to 64-bit precision
2798 and Python's configure script is unable to determine how to change the FPU
2799 precision. On these platforms conversions use the platform strtod and dtoa,
2800 as before.
Mark Dickinsonb678de82009-11-19 18:41:49 +00002801
Georg Brandlba83f822010-03-14 09:50:54 +00002802- Issue #7117: Backport round implementation from Python 3.x. ``round()`` now
2803 uses the correctly-rounded string <-> float conversions described above (when
2804 available), and so produces correctly rounded results that will display nicely
2805 under the float repr. There are two related small changes: (1) round now
2806 accepts any class with an ``__index__()`` method for its second argument (but
2807 no longer accepts floats for the second argument), and (2) an excessively
2808 large second integer argument (e.g., ``round(1.234, 10**100)``) no longer
2809 raises an exception.

2938
Georg Brandlba83f822010-03-14 09:50:54 +00002939- Issue #5829: complex("1e500") no longer raises OverflowError. This makes it
2940 consistent with float("1e500") and interpretation of real and imaginary
2941 literals.

Mark Dickinsonb1d45852009-05-11 15:33:08 +00002950- Issue #5981: Fix three minor inf/nan issues in float.fromhex:
Mark Dickinsonb1d45852009-05-11 15:33:08 +00002951
Georg Brandlba83f822010-03-14 09:50:54 +00002952 (1) inf and nan strings with trailing whitespace were incorrectly rejected;
2953 (2) parsing of strings representing infinities and nans was locale aware; and
2954 (3) the interpretation of fromhex('-nan') didn't match that of float('-nan').
Eric Smitha985a3a2009-05-05 18:26:08 +00002955
Georg Brandlba83f822010-03-14 09:50:54 +00002956- Issue #5920: For ``float.__format__()``, change the behavior with the empty
2957 presentation type (that is, not one of 'e', 'f', 'g', or 'n') to be like 'g'
2958 but with at least one decimal point and with a default precision
2959 of 12. Previously, the behavior the same but with a default precision of 6.
2960 This more closely matches ``str()``, and reduces surprises when adding
2961 alignment flags to the empty presentation type. This also affects the new
2962 complex.__format__ in the same way.
2963
2964- Issue #5890: In subclasses of 'property' the __doc__ attribute was shadowed by
2965 classtype's, even if it was None. property now inserts the __doc__ into the
2966 subclass instance __dict__.

Antoine Pitrouf8387af2009-03-23 18:41:45 +00003026- Issue #4688: Add a heuristic so that tuples and dicts containing only
Georg Brandlba83f822010-03-14 09:50:54 +00003027 untrackable objects are not tracked by the garbage collector. This can reduce
3028 the size of collections and therefore the garbage collection overhead on

3036 internal representation of integers, for performance reasons. Base 2**30 is
3037 enabled by default on 64-bit machines. Add --enable-big-digits option to
3038 configure, which overrides the default. Add sys.long_info structseq to
3039 provide information about the internal format.

Georg Brandlba83f822010-03-14 09:50:54 +00003186- On windows, ``os.chdir()`` given unicode was not working if

3188 this code path is really executed because I cannot move to such directory on
3189 win2k)

Georg Brandlba83f822010-03-14 09:50:54 +00003191- Issue #4069: When ``set.remove(element)`` is used with a set element, the
3192 element is temporarily replaced with an equivalent frozenset. But the
3193 eventual KeyError would always report the empty ``frozenset()`` as the missing

Walter Dörwalded960ac2009-05-03 22:36:33 +00003214- Issue #5108: Handle %s like %S and %R in PyUnicode_FromFormatV(): Call
3215 PyUnicode_DecodeUTF8() once, remember the result and output it in a second
3216 step. This avoids problems with counting UTF-8 bytes that ignores the effect
3217 of using the replace error handler in PyUnicode_DecodeUTF8().
3218
Walter Dörwald726ba8e2009-05-06 14:32:35 +00003219- Issue #3739: The unicode-internal encoder now reports the number of characters

3221
Georg Brandlba83f822010-03-14 09:50:54 +00003222- Issue #2422: When compiled with the ``--with-valgrind`` option, the pymalloc
3223 allocator will be automatically disabled when running under Valgrind. This
3224 gives improved memory leak detection when running under Valgrind, while taking
3225 advantage of pymalloc at other times.

Georg Brandlba83f822010-03-14 09:50:54 +00004389 - If x is not an int, long or float, then packing x will always result in
4390 struct.error. Previously an x with an __int__ method could be packed by
4391 'b', 'B', 'h', 'H', 'i', 'l', '*b', '*h' ,'*i', '*l', and an x with a
4392 __long__ method could be packed by 'q', 'Q', '*q', '*Q'; for x with
4393 neither __int__ nor __long__, TypeError used to be raised (with a
4394 confusing error message) for 'I', 'L', '*B', '*H', '*I', '*L', and
4395 struct.error in other cases.

4398 argument with an __int__ method can be packed, but use of this feature
4399 triggers a DeprecationWarning.

Martin v. Löwis9fa5a282008-09-11 06:53:30 +00004590- Issue #3642: Suppress warning in obmalloc when size_t is larger than uint.
4591
Amaury Forgeot d'Arc05e34492008-09-10 22:04:45 +00004592- Issue #3743: In a few places, PY_FORMAT_SIZE_T was incorrectly used with
4593 PyString_FromFormat or PyErr_Format to display size_t values. The macro
4594 PY_FORMAT_SIZE_T is designed to select the correct format for the OS
4595 ``printf`` function, whereas PyString_FromFormat has an independent
4596 implementation and uses "%zd" on all platforms for size_t values.
4597 This makes a difference on win64, where ``printf`` needs "%Id" to display
4598 64bit values.
4599
Benjamin Peterson97179b02008-09-09 20:55:01 +00004600- Issue #3634: _weakref.ref(Exception).__init__() gave invalid return value on
4601 error.
4602
Amaury Forgeot d'Arcd3ffb892008-09-09 07:24:30 +00004603- Issue #3777: long() applied to a float object now always return a long
4604 object; previously an int would be returned for small values. the __long__
4605 method is allowed to return either an int or a long, but the behaviour of
4606 float objects should not change to respect backward compatibility.
4607
Amaury Forgeot d'Arc3571fbf2008-09-01 19:52:00 +00004608- Issue #3751: str.rpartition would perform a left-partition when called with
4609 a unicode argument.
4610
Benjamin Peterson17f03ca2008-09-01 14:18:30 +00004611- Issue #3683: Fix compilation when --without-threads is given.

Vinay Sajip35e3b032008-09-01 14:33:59 +00004614 PyArg_ParseTuple and friends, which occurred when the argument for "s*"
Antoine Pitroud4ae97b2008-08-29 18:39:48 +00004615 was correctly parsed but parsing of subsequent arguments failed.
4616
Vinay Sajip35e3b032008-09-01 14:33:59 +00004617- Issue #2534: speed up isinstance() and issubclass() by 50-70%, so as to
Antoine Pitrou0668c622008-08-26 22:42:08 +00004618 match Python 2.5 speed despite the __instancecheck__ / __subclasscheck__
4619 mechanism. In the process, fix a bug where isinstance() and issubclass(),
4620 when given a tuple of classes as second argument, were looking up
4621 __instancecheck__ / __subclasscheck__ on the tuple rather than on each
4622 type object.
4623
Neal Norwitz18aa3882008-08-24 05:04:52 +00004624- Fix crashes on memory allocation failure found with failmalloc.

4633 function 'stringlib_contains_obj'.

Brett Cannon672237d2008-09-09 00:49:16 +00004667 return a list or None rather than a custom object.
4668
Benjamin Peterson6ac7d7c2008-09-06 19:28:11 +00004669- Issue #1638033: Cookie.Morsel gained the httponly attribute.

Georg Brandl222e2082010-08-01 22:27:39 +00004692- Issue #3602: Moved test.test_support.catch_warning() to
Brett Cannon1eaf0742008-09-02 01:25:16 +00004693 warnings.catch_warnings() along with some API cleanup. Expanding the tests
4694 for catch_warnings() also led to an improvement in the raising of a
4695 DeprecationWarning related to warnings.warn_explicit().
4696
Benjamin Peterson973e6c22008-09-01 23:12:58 +00004697- The deprecation warnings for the old camelCase threading API were removed.

4767-----------------
4768
Guido van Rossumf8402962008-08-20 15:01:50 +00004769- Issue #1878: Remove Py_TPFLAGS_HAVE_VERSION_TAG from
4770 Py_TPFLAGS_DEFAULT when not building the core. This means 3rd party
4771 extensions do not automatically benefit from the class attribute
4772 cache; they will have to explicitly add Py_TPFLAGS_HAVE_VERSION_TAG
4773 to their tp_flags field if they care. This is a backwards
4774 compatibility feature; in 3.0, all types will use the cache by
4775 default.
4776
Benjamin Petersonf647dc12008-08-20 01:27:30 +00004777- Keyword arguments can now follow starred arguments. (``f(a, *args,
4778 keyword=23)`` is now valid syntax.)
4779
Thomas Heller0ad5ae02008-08-19 19:25:04 +00004780- ctypes function pointers that are COM methods have a boolean True
4781 value again.
4782
Martin v. Löwisf91d46a2008-08-12 14:49:50 +00004783- Issue #3139: Make buffer-interface thread-safe wrt. PyArg_ParseTuple,
4784 by denying s# to parse objects that have a releasebuffer procedure,
4785 and introducing s*.
4786
Georg Brandl1e13ea92008-08-11 09:07:59 +00004787- Issue #3537: Fix an assertion failure when an empty but presized dict
4788 object was stored in the freelist.
4789
Mark Dickinsonb6467572008-08-04 21:30:09 +00004790- Issue #1481296: Make long(float('nan')) and int(float('nan')) raise
4791 ValueError consistently across platforms.
4792
Amaury Forgeot d'Arc39fd6722008-07-31 21:28:03 +00004793- Issue #3479: On platforms where sizeof(int) is smaller than sizeof(long)
4794 (64bit Unix, for example), unichr() would truncate its argument and return
4795 u'\x00' for unichr(2**32). Now it properly raises an OverflowError.
4796
Neal Norwitze7d8be82008-07-31 17:17:14 +00004797- Apply security patches from Apple.
4798
Amaury Forgeot d'Arc246daed2008-07-31 00:42:16 +00004799- Issue #2542: Now that issubclass() may call arbitrary code, ensure that
4800 PyErr_ExceptionMatches returns 0 when an exception occurs there.
4801
Antoine Pitrou92f82162008-07-25 22:22:08 +00004802- Issue #1819: function calls with several named parameters are now on
4803 average 35% faster (as measured by pybench).
4804
Amaury Forgeot d'Arce4921fe2008-07-21 22:00:38 +00004805- Issue #2378: An unexpected UnboundLocalError or NameError could appear when
4806 the python debugger steps into a class statement: the free variables (local
4807 variables defined in an outer scope) would be deleted from the outer scope.
4808
Gregory P. Smith0470bab2008-07-22 04:46:32 +00004809- Issue #2620: Overflow checking when allocating or reallocating memory
4810 was not always being done properly in some python types and extension
4811 modules. PyMem_MALLOC, PyMem_REALLOC, PyMem_NEW and PyMem_RESIZE have
4812 all been updated to perform better checks and places in the code that
4813 would previously leak memory on the error path when such an allocation
4814 failed have been fixed.

4818
Hirokazu Yamamoto838c79f2008-08-20 13:14:07 +00004819- Issue #3612: Added some missing basic types in ctypes.wintypes.
4820
Benjamin Petersone977ad42008-08-20 01:42:01 +00004821- The methods ``is_in_tuple()``, ``is_vararg()``, and ``is_keywordarg()`` of
4822 symtable.Symbol have been deprecated for removal in 3.0 and the next release.
4823
Amaury Forgeot d'Arc351ffb82008-08-18 19:23:47 +00004824- Issue #2234: distutils failed for some versions of the cygwin compiler. The
4825 version reported by these tools does not necessarily follow the python
4826 version numbering scheme, so the module is less strict when parsing it.
4827
Nick Coghlanf70385a2008-08-18 12:42:46 +00004828- Issue #2235: Added Py3k warnings for types which will become unhashable
4829 under the stricter __hash__ inheritance rules in 3.0. Several types
4830 which did not meet the rules for hash invariants and were already
4831 unhashable in 3.0 have now been explicitly flagged as unhashable in
4832 2.6 as well (collections.Mapping, collections.Set, unittest.TestSuite,
4833 xml.dom.minidom.NamedNodeMap, numbers.Number, UserList.UserList)
4834
Brett Cannon88f801d2008-08-18 00:46:22 +00004835- Update __all__ for cookielib, csv, os, urllib2, and weakref to include things

4948
Nick Coghlan2a0c2b12008-08-04 12:47:17 +00004949- Issue #643841: The language reference now provides more detailed

4961-----------------
4962
Georg Brandl3e483f62008-07-16 22:57:41 +00004963- Issue #3156: Fix inconsistent behavior of the bytearray type: all
4964 its methods now allow for items objects that can be converted to
4965 an integer using operator.index().
4966
Mark Dickinson64b7e502008-07-16 09:40:03 +00004967- Issue #3360: Fix incorrect parsing of '020000000000.0', which
4968 produced a ValueError instead of giving the correct float.
4969
Eric Smitha5fa5a22008-07-16 00:11:49 +00004970- Issue #3083: Add alternate (#) formatting for bin, oct, hex output
4971 for str.format(). This adds the prefix 0b, 0o, or 0x, respectively.
4972
Mark Dickinson7103aa42008-07-15 19:08:33 +00004973- Issue #3008: the float type has a new instance method 'float.hex'
4974 and a new class method 'float.fromhex' to convert floating-point
4975 numbers to and from hexadecimal strings, respectively.
4976
Nick Coghlan6d6bd442008-07-15 15:40:22 +00004977- Issue #2235: __hash__ is once again inherited by default. To allow
4978 collections.Hashable to remain meaningful in the presence of the
4979 default hash implementation (object.__hash__), it is now possible
4980 to explicit block inheritance of hash by setting __hash__=None at
4981 the Python level, or tp_hash=PyObject_HashNotImplemented at the C
4982 level.
4983
Nick Coghlanb028f502008-07-13 14:52:36 +00004984- Issue #3221: Issue a RuntimeWarning instead of raising SystemError if
4985 the parent module cannot be found while performing an absolute import.
4986 This means that an incorrectly defined __package__ attribute will
4987 now only prevent relative imports in that module rather than causing
4988 all imports from that module to fail.
4989
Nick Coghlan14ff9942008-07-08 14:21:42 +00004990- Issue #2517: Allow unicode messages in Exceptions again by correctly

5000 another thread's dictionary.
5001
Mark Dickinson1ec2fcd2008-06-20 14:53:43 +00005002- Issue #3004: Minor change to slice.indices(): the start and stop
5003 arguments are now treated identically, making the behaviour easier
5004 to describe and understand. For example, slice(None, -10,
5005 1).indices(9) now returns (0, 0, 1) instead of (0, -1, 1), and
5006 slice(None, 10, -1).indices(10) returns (9, 9, -1) instead of (9,
5007 10, -1).
5008
Georg Brandl278fc502008-07-19 12:46:12 +00005009- Issue #3219: Calling a function with repeated keyword arguments,
5010 f(a=2, a=23), would not cause a syntax error. This was a regression
5011 from 2.4 caused by the switch to the new compiler.

5050 both unnecessary (HTTP allows text content to be sent in several forms) and
Andrew M. Kuchlingcc3f2b12008-07-10 14:43:31 +00005051 wrong because the actual transmitted size could differ from the

Ronald Oussoren5640ce22008-06-05 12:58:24 +00005459- On MacOS X it is now possible to install the framework in 64-bit
5460 mode or even as a 4-way universal binary (that is, PPC, i386,
Georg Brandl5cc774e2008-06-11 20:28:06 +00005461 PPC64 and x86_64 support in one binary).
Ronald Oussoren5640ce22008-06-05 12:58:24 +00005462
5463 This is controlled by the configure argument ``--with-universal-archs``:
5464
5465 - ``--with-universal-archs=all``: install 4-way universal
5466
5467 - ``--with-universal-archs=32-bit``: install 2-way universal, 32-bit (the default)
5468
5469 - ``--with-universal-archs=64-bit``: install 2-way universal, 64-bit
5470
5471 This option should be used in combination with ``--enable-universalsdk=``.
5472
5473 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 +00005523- Issue #1631171: Re-implement the 'warnings' module in C (the
5524 original Python code has been kept as backup). This will allow for
5525 using the 'warning's machinery in such places as the parser where
5526 use of pure Python code is not possible. Both the ``showarning()``
5527 and ``formatwarning()`` gain an optional 'line' argument which is
5528 not called by default for backwards-compatibility reasons. Setting
5529 ``warnings.showwarning()`` to an implementation that lacks support
5530 for the ``line`` argument will raise a DeprecationWarning.

Georg Brandl3ee81df2008-05-17 18:14:43 +00005593- Issue #2550: The approach used by client/server code for obtaining
5594 ports to listen on in network-oriented tests has been refined in an
5595 effort to facilitate running multiple instances of the entire
5596 regression test suite in parallel without issue.
5597 test_support.bind_port() has been fixed such that it will always
5598 return a unique port -- which wasn't always the case with the
5599 previous implementation, especially if socket options had been set
5600 that affected address reuse (i.e. SO_REUSEADDR, SO_REUSEPORT). The
5601 new implementation of bind_port() will actually raise an exception
5602 if it is passed an AF_INET/SOCK_STREAM socket with either the
5603 SO_REUSEADDR or SO_REUSEPORT socket option set. Furthermore, if
5604 available, bind_port() will set the SO_EXCLUSIVEADDRUSE option on
5605 the socket it's been passed. This currently only applies to
5606 Windows. This option prevents any other sockets from binding to the
5607 host/port we've bound to, thus removing the possibility of the
5608 'non-deterministic' behaviour, as Microsoft puts it, that occurs
5609 when a second SOCK_STREAM socket binds and accepts to a host/port
5610 that's already been bound by another socket. The optional preferred
5611 port parameter to bind_port() has been removed. Under no
5612 circumstances should tests be hard coding ports!
5613
5614 test_support.find_unused_port() has also been introduced, which will
5615 pass a temporary socket object to bind_port() in order to obtain an
5616 unused port. The temporary socket object is then closed and
5617 deleted, and the port is returned. This method should only be used
5618 for obtaining an unused port in order to pass to an external program
5619 (i.e. the -accept [port] argument to openssl's s_server mode) or as
5620 a parameter to a server-oriented class that doesn't give you direct
5621 access to the underlying socket used.
5622
5623 Finally, test_support.HOST has been introduced, which should be used
5624 for the host argument of any relevant socket calls (i.e. bind and
5625 connect).
Trent Nelsone41b0062008-04-08 23:47:30 +00005626
5627 The following tests were updated to following the new conventions:
Georg Brandl3ee81df2008-05-17 18:14:43 +00005628 test_socket, test_smtplib, test_asyncore, test_ssl, test_httplib,
Trent Nelsone41b0062008-04-08 23:47:30 +00005629 test_poplib, test_ftplib, test_telnetlib, test_socketserver,
5630 test_asynchat and test_socket_ssl.
5631
Georg Brandl3ee81df2008-05-17 18:14:43 +00005632 It is now possible for multiple instances of the regression test
5633 suite to run in parallel without issue.

Amaury Forgeot d'Arc9a0d3462008-03-23 09:55:29 +00005687- Issue #1477: With narrow Unicode builds, the unicode escape sequence
Georg Brandl3ee81df2008-05-17 18:14:43 +00005688 \Uxxxxxxxx did not accept values outside the Basic Multilingual
5689 Plane. This affected raw unicode literals and the
5690 'raw-unicode-escape' codec. Now UTF-16 surrogates are generated in
5691 this case, like normal unicode literals and the 'unicode-escape'
5692 codec.

Eric Smitha73fbe72008-02-23 03:09:44 +00005912- Added the future_builtins module, which contains hex() and oct().
5913 These are the PEP 3127 version of these functions, designed to be
5914 compatible with the hex() and oct() builtins from Python 3.0. They
5915 differ slightly in their output formats from the existing, unchanged
5916 Python 2.6 builtins. The expected usage of the future_builtins
5917 module is:
5918 from future_builtins import hex, oct
5919
Eric Smith7ef40bf2008-02-20 23:34:22 +00005920- Issue #1600: Modifed PyOS_ascii_formatd to use at most 2 digit
5921 exponents for exponents with absolute value < 100. Follows C99
5922 standard. This is a change on Windows, which would use 3 digits.
5923 Also, added 'n' to the formats that PyOS_ascii_formatd understands,
5924 so that any alterations it does to the resulting string will be
5925 available in stringlib/formatter.h (for float.__format__).
5926
Eric Smith5a3c1352008-02-19 13:21:56 +00005927- Implemented PEP 3101, Advanced String Formatting. This adds a new
5928 builtin format(); a format() method for str and unicode; a
5929 __format__() method to object, str, unicode, int, long, float, and
5930 datetime; the class string.Formatter; and the C API
5931 PyObject_Format().
5932
Georg Brandl3ee81df2008-05-17 18:14:43 +00005933- Fixed several potential crashes, all caused by specially crafted
5934 __del__ methods exploiting objects in temporarily inconsistent
5935 state.
Amaury Forgeot d'Arc632fad32008-02-16 20:55:24 +00005936
Vinay Sajipb7edfc42008-04-02 21:10:23 +00005937- Issue #2115: Important speedup in setting __slot__ attributes. Also
Georg Brandl3ee81df2008-05-17 18:14:43 +00005938 prevent a possible crash: an Abstract Base Class would try to access
5939 a slot on a registered virtual subclass.
Amaury Forgeot d'Arc60d6c7f2008-02-15 21:22:45 +00005940

Georg Brandl3ee81df2008-05-17 18:14:43 +00005944- Clear all free lists during a gc.collect() of the highest generation
5945 in order to allow pymalloc to free more arenas. Python may give back
5946 memory to the OS earlier.
Christian Heimes3b718a72008-02-14 12:47:33 +00005947
Georg Brandl3ee81df2008-05-17 18:14:43 +00005948- Issue #2045: Fix an infinite recursion triggered when printing a
5949 subclass of collections.defaultdict, if its default_factory is set
5950 to a bound method.

Georg Brandl3ee81df2008-05-17 18:14:43 +00005978- Patch #1473257: generator objects gain a gi_code attribute. This is
5979 the same object as the func_code attribute of the function that
5980 produced the generator.
Georg Brandl0cdf9a32008-01-26 14:14:20 +00005981
Georg Brandl3ee81df2008-05-17 18:14:43 +00005982- Issue #1920: "while 0" statements were completely removed by the
5983 compiler, even in the presence of an "else" clause, which is
5984 supposed to be run when the condition is false. Now the compiler
5985 correctly emits bytecode for the "else" suite.
Amaury Forgeot d'Arc31eaafe2008-01-24 22:59:25 +00005986
Guido van Rossumeead05f2008-01-24 18:21:02 +00005987- A few crashers fixed: weakref_in_del.py (issue #1377858);
5988 loosing_dict_ref.py (issue #1303614, test67.py);
5989 borrowed_ref_[34].py (not in tracker).

5994
Georg Brandl3ee81df2008-05-17 18:14:43 +00005995- Issue #1915: Python compiles with --enable-unicode=no again. However
Christian Heimes082c9b02008-01-23 14:20:50 +00005996 several extension methods and modules do not work without unicode
5997 support.
5998

6003
Georg Brandl6caad7d2008-01-26 14:19:22 +00006004- Issue #1865: ``bytes`` as an alias for ``str`` and b"" as an alias "" were
Christian Heimes288e89a2008-01-18 18:24:07 +00006005 added.
6006
Christian Heimesc94e2b52008-01-14 04:13:37 +00006007- sys.float_info / PyFloat_GetInfo: The floating point information
6008 object was converted from a dict to a specialized structseq object.
6009
Georg Brandl3ee81df2008-05-17 18:14:43 +00006010- Patch #1816: Added sys.flags structseq. It exposes the status of
6011 most command line arguments and PYTHON* environment variables.
Christian Heimesf31b69f2008-01-14 03:42:48 +00006012
Georg Brandl3ee81df2008-05-17 18:14:43 +00006013- Objects/structseq.c: Implemented new structseq representation. The
6014 patch makes structseqs (e.g. the return value of os.stat) more
6015 readable.
Christian Heimes9c201962008-01-14 03:33:52 +00006016
Georg Brandl3ee81df2008-05-17 18:14:43 +00006017- Patch #1700288: added a type attribute cache that caches method
6018 accesses, resulting in speedups in heavily object-oriented code.
Amaury Forgeot d'Arce4c270c2008-01-14 00:29:41 +00006019
Neal Norwitz3fc15b82008-01-10 05:42:58 +00006020- Bug #1776: __import__() no longer accepts filenames on any platform.

6026 envvar and sys.dont_write_bytecode attribute. All these can be set
6027 to forbid Python to attempt to write compiled bytecode files.
Georg Brandl2da0fce2008-01-07 17:09:35 +00006028
Georg Brandl3ee81df2008-05-17 18:14:43 +00006029- Improve some exception messages when Windows fails to load an
6030 extension module. Now we get for example '%1 is not a valid Win32
6031 application' instead of 'error code 193'.

Christian Heimes0a8143f2007-12-18 23:22:54 +00006038- Issue #1635: Platform independent creation and representation of NaN
Georg Brandl3ee81df2008-05-17 18:14:43 +00006039 and INF. float("nan"), float("inf") and float("-inf") now work on
6040 every platform with IEEE 754 semantics.
Christian Heimes0a8143f2007-12-18 23:22:54 +00006041
Georg Brandl3ee81df2008-05-17 18:14:43 +00006042- Compiler now generates simpler and faster code for dictionary

6088
Georg Brandl21e99f42010-03-07 15:23:59 +00006089- The enumerate() built-in function is no longer bounded to sequences
Georg Brandl3ee81df2008-05-17 18:14:43 +00006090 smaller than LONG_MAX. Formerly, it raised an OverflowError. Now,
6091 automatically shifts from ints to longs.
Raymond Hettinger8f669372007-10-03 21:18:11 +00006092
Georg Brandl3ee81df2008-05-17 18:14:43 +00006093- Issue #1686386: Tuple's tp_repr did not take into account the
6094 possibility of having a self-referential tuple, which is possible
6095 from C code. Nor did object's tp_str consider that a type's tp_str
6096 could do something that could lead to an inifinite recursion.
6097 Py_ReprEnter() and Py_EnterRecursiveCall(), respectively, fixed the
6098 issues.
Brett Cannon0b14f242007-09-30 19:45:10 +00006099

6101 'print' statement to write to a file since the GIL was not released
6102 as needed. Now PyObject_Print() does the right thing along with
6103 various tp_print implementations of the built-in types and those in
6104 the collections module.
Brett Cannon01531592007-09-17 03:28:34 +00006105

Georg Brandl3ee81df2008-05-17 18:14:43 +00006114 PyObject_Call() never calling back out to Python code to trigger
6115 recursion depth updates/checks. Required the creation of a static
6116 RuntimeError instance in case normalizing an exception put the
6117 recursion check value past its limit. Fixes crashers

Guido van Rossum143b5642007-03-23 04:58:42 +00006166- Bug #1683368: The object.__init__() and object.__new__() methods are
6167 now stricter in rejecting excess arguments. The only time when
6168 either allows excess arguments is when it is not overridden and the
6169 other one is. For backwards compatibility, when both are
6170 overridden, it is a deprecation warning (for now; maybe a Py3k
Guido van Rossum234b1ff2007-03-23 19:39:01 +00006171 warning later). Also, type.__init__() insists on the same signature
6172 as supported by type.__new__().

Georg Brandl3ee81df2008-05-17 18:14:43 +00006174- Patch #1675423: PyComplex_AsCComplex() now tries to convert an
6175 object to complex using its __complex__() method before falling back
6176 to the __float__() method. Therefore, the functions in the cmath
6177 module now can operate on objects that define a __complex__()
6178 method.

Georg Brandl7b9c5552007-03-12 14:30:05 +00006196- Bug #1678647: write a newline after printing an exception in any
6197 case, even when converting the value to a string failed.
6198
Georg Brandl871f1bc2007-03-12 13:17:36 +00006199- The dir() function has been extended to call the __dir__() method on
Georg Brandl3ee81df2008-05-17 18:14:43 +00006200 its argument, if it exists. If not, it will work like before. This
6201 allows customizing the output of dir() in the presence of a
6202 __getattr__().

6212 raising a ValueError.
Collin Wintere38051d2007-03-09 20:33:07 +00006213
Georg Brandlaa2321b2007-03-07 00:40:28 +00006214- Patch #703779: unset __file__ in __main__ after running a file. This
Georg Brandl3ee81df2008-05-17 18:14:43 +00006215 makes the filenames the warning module prints much more sensible
6216 when a PYTHONSTARTUP file is used.

6230 sq_ass_slice instead of the sq_slice slot.
6231
Georg Brandl3ee81df2008-05-17 18:14:43 +00006232- When printing an unraisable error, don't print exceptions. before

Georg Brandl2c1375c2006-10-12 11:27:59 +00006284- Bug #1545497: when given an explicit base, int() did ignore NULs
6285 embedded in the string to convert.
6286
Georg Brandl846f73a2006-10-08 07:11:54 +00006287- Bug #1569998: break inside a try statement (outside a loop) is now

Georg Brandl3ee81df2008-05-17 18:14:43 +00006335 generator expressions (x for x, in ... ) works again. Fixing this
6336 problem required changing the .pyc magic number. This means that
6337 .pyc files generated before 2.5c2 will be regenerated.

Georg Brandl3ee81df2008-05-17 18:14:43 +00006767 AttributeError instead of an IOError when the server's response

6859 TestCase and TestSuite subclasses (not instances) are no longer
6860 accepted in TestSuite.addTest(). This should cause no
6861 incompatibility since it never made sense with ordinary subclasses
6862 -- the failure just occurred later, with a more cumbersome
6863 exception.

Georg Brandl3ee81df2008-05-17 18:14:43 +00007140- The implementation of UnicodeError objects has been simplified
7141 (start and end attributes are now stored directly as Py_ssize_t
7142 members).
Walter Dörwald84a3efe2007-06-13 16:57:12 +00007143
Georg Brandl3ee81df2008-05-17 18:14:43 +00007144- Issue #829951: In the smtplib module, SMTP.starttls() now complies
7145 with RFC 3207 and forgets any knowledge obtained from the server not
7146 obtained from the TLS negotiation itself. Patch contributed by Bill
7147 Fenner.
Gregory P. Smith2b3ba582008-01-17 08:03:17 +00007148
Georg Brandl3ee81df2008-05-17 18:14:43 +00007149- Issue #1339: The smtplib.SMTP class has been refactored a bit such
Gregory P. Smithbde4ae42008-01-17 08:35:49 +00007150 that the SMTP.starttls() caller no longer needs to call ehlo()
7151 beforehand. SMTP.starttls() now raises an exception of the server
Georg Brandl3ee81df2008-05-17 18:14:43 +00007152 does not claim to support starttls. Adds the
7153 SMTP.ehlo_or_helo_if_needed() method. Patch contributed by Bill
7154 Fenner.

Georg Brandl3ee81df2008-05-17 18:14:43 +00007233- Marshal.dumps() now expects exact type matches for int, long, float,
7234 complex, tuple, list, dict, set, and frozenset. Formerly, it would
7235 silently miscode subclasses of those types. Now, it raises a
7236 ValueError instead.
Raymond Hettinger12e94202007-11-07 01:13:09 +00007237

Georg Brandl3ee81df2008-05-17 18:14:43 +00007252 time so that opening a database previously created with the DB_DUP
7253 or DB_DUPSORT flag set will keep the proper behavior on subsequent
7254 opens. Specifically: dictionary assignment to a DB object will
7255 replace all values for a given key when the database allows
7256 duplicate values. DB users should use DB.put(k, v) when they want
7257 to store duplicates; not DB[k] = v.
Gregory P. Smithec10a4a2007-11-05 02:32:26 +00007258

7264 characters with ASCII value less than 32. Also, it correctly quotes
7265 dots only if they occur on a single line, as opposed to the previous
7266 behavior of quoting dots if they are the second character of any
7267 line.
Georg Brandl4aef7272007-03-13 22:49:43 +00007268

7658 builds.

Georg Brandl3ee81df2008-05-17 18:14:43 +00007673- Removed the macfs module. It had been deprecated since Python 2.5.
7674 This lead to the deprecation of macostools.touched() as it relied
7675 solely on macfs and was a no-op under OS X.
