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
Barry Warsawc5643282011-07-19 17:06:30 -040057- dict_proxy objects now display their contents rather than just the class
58 name.

190
Ned Deily87e82bb2011-06-28 19:52:59 -0700191- Issue #9516: On Mac OS X, change Distutils to no longer globally attempt to
192 check or set the MACOSX_DEPLOYMENT_TARGET environment variable for the
193 interpreter process. This could cause failures in non-Distutils subprocesses
194 and was unreliable since tests or user programs could modify the interpreter
195 environment after Distutils set it. Instead, have Distutils set the the
196 deployment target only in the environment of each build subprocess. It is
197 still possible to globally override the default by setting
198 MACOSX_DEPLOYMENT_TARGET before launching the interpreter; its value must be
199 greater or equal to the default value, the value with which the interpreter
200 was built.
201
Raymond Hettinger2c316a32011-06-25 17:14:53 +0200202- Issue #11802: The cache in filecmp now has a maximum size of 100 so that

207
R David Murrayf1138bb2011-06-17 22:23:04 -0400208- Issue #11700: mailbox proxy object close methods can now be called multiple
209 times without error, and _ProxyFile now closes the wrapped file.
210
Victor Stinnerc74a6ba2011-06-17 14:06:27 +0200211- Issue #12133: AbstractHTTPHandler.do_open() of urllib.request closes the HTTP
212 connection if its getresponse() method fails with a socket error. Patch
213 written by Ezio Melotti.
214
Benjamin Peterson0eb4ac42011-06-11 15:53:11 -0500215- Issue #9284: Allow inspect.findsource() to find the source of doctest
216 functions.
217
R David Murray873c5832011-06-09 16:01:09 -0400218- Issue #10694: zipfile now ignores garbage at the end of a zipfile.
219
Brian Curtincaea7e82011-06-08 19:29:53 -0500220- Issue #11583: Speed up os.path.isdir on Windows by using GetFileAttributes

222

224 some corner-case Decimal.__pow__ calls to take an unreasonably long time.
225

227
Barry Warsawc5643282011-07-19 17:06:30 -0400228- sys.setcheckinterval() now updates the current ticker count as well as
229 updating the check interval, so if the user decreases the check interval,
230 the ticker doesn't have to wind down to zero from the old starting point
231 before the new interval takes effect. And if the user increases the
232 interval, it makes sure the new limit takes effect right away rather have an
233 early task switch before recognizing the new interval.
Raymond Hettinger19b851d2011-06-01 18:21:42 -0700234
Victor Stinner776e69b2011-06-01 01:03:00 +0200235- Issue #12085: Fix an attribute error in subprocess.Popen destructor if the

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

1116
Raymond Hettinger20397532010-09-12 02:11:45 +00001117- Issue #9825: removed __del__ from the definition of collections.OrderedDict.
1118 This prevents user-created self-referencing ordered dictionaries from
1119 becoming permanently uncollectable GC garbage. The downside is that
1120 removing __del__ means that the internal doubly-linked list has to wait for
1121 GC collection rather than freeing memory immediately when the refcnt drops
1122 to zero.
1123

1127
Antoine Pitrouc818ed42010-09-07 21:40:25 +00001128- Issue #9792: In case of connection failure, socket.create_connection()
1129 would swallow the exception and raise a new one, making it impossible
1130 to fetch the original errno, or to filter timeout errors. Now the
1131 original error is re-raised.

R. David Murray7c4bf552010-08-25 01:45:57 +00001153- Issue #1194222: email.utils.parsedate now returns RFC2822 compliant four

Ezio Melottiab2eb0e2010-06-05 19:21:32 +00001581- Issue #8271: during the decoding of an invalid UTF-8 byte sequence, only the
1582 start byte and the continuation byte(s) are now considered invalid, instead
1583 of the number of bytes specified by the start byte.
1584 E.g.: '\xf1\x80AB'.decode('utf-8', 'replace') now returns u'\ufffdAB' and
1585 replaces with U+FFFD only the start byte ('\xf1') and the continuation byte
1586 ('\x80') even if '\xf1' is the start byte of a 4-bytes sequence.
1587 Previous versions returned a single u'\ufffd'.

1591 arises from the "Overriding __eq__ blocks inheritance ..." warning
1592 when turned into an exception: in this case the exception simply
1593 gets ignored.

Mark Dickinson4ca7c3c2010-05-30 13:18:10 +00001595- Issue #8748: Fix two issues with comparisons between complex and integer
1596 objects. (1) The comparison could incorrectly return True in some cases
1597 (2**53+1 == complex(2**53) == 2**53), breaking transivity of equality.
1598 (2) The comparison raised an OverflowError for large integers, leading
1599 to unpredictable exceptions when combining integers and complex objects
1600 in sets or dicts.
1601
Mark Dickinson81336372010-05-30 12:12:25 +00001602- Issue #5211: Implicit coercion for the complex type is now completely

Georg Brandlba83f822010-03-14 09:50:54 +00002480 file position when calling `truncate()`. It would previously change the file
2481 position to the given argument, which goes against the tradition of

2486 implementation is significantly faster and can be wrapped in a

2488 where interleaved calls to ``read()`` and ``readline()`` give wrong results.

Georg Brandlba83f822010-03-14 09:50:54 +00002579- The ``__complex__()`` method is now looked up on the class of instances to

2584
Mark Dickinson1b34d252010-01-01 17:27:30 +00002585- Issue #5080: A number of functions and methods previously produced a
Georg Brandlba83f822010-03-14 09:50:54 +00002586 DeprecationWarning when passed a float argument where an integer was expected.
2587 These functions and methods now raise TypeError instead. The majority of the
2588 effects of this change are in the extension modules, but some core functions
2589 and methods are affected: notably the 'chr', 'range' and 'xrange' builtins,
2590 and many unicode/str methods.

2606 internal representation of a long.

2614
Georg Brandlba83f822010-03-14 09:50:54 +00002615 These executables now work properly with the arch(1) command: ``arch -ppc

2703 ``PyArg_ParseTupleAndKeywords()``, ``PyArg_VaParse()``,
2704 ``PyArg_VaParseTupleAndKeywords()`` and ``PyArg_Parse()`` no longer accept
2705 float arguments for integer format codes (other than 'L'): previously an
2706 attempt to pass a float resulted in a DeprecationWarning; now it gives a
2707 TypeError. For the 'L' format code (which previously had no warning) there is
2708 now a DeprecationWarning.

2757 to 'g' for large values.
Amaury Forgeot d'Arcd7288712009-12-01 21:51:04 +00002758

2760 1e50 in absolute value.

Ronald Oussoren315cd0c2009-11-19 16:25:21 +00002772
Georg Brandlba83f822010-03-14 09:50:54 +00002773- Issue #7117: ``repr(x)`` for a float x returns a result based on the shortest
2774 decimal string that's guaranteed to round back to x under correct rounding
2775 (with round-half-to-even rounding mode). Previously it gave a string based on
2776 rounding x to 17 decimal digits. repr(x) for a complex number behaves
2777 similarly. On platforms where the correctly-rounded strtod and dtoa code is
2778 not supported (see below), repr is unchanged.
Mark Dickinsonb678de82009-11-19 18:41:49 +00002779
Georg Brandlba83f822010-03-14 09:50:54 +00002780- Issue #7117: On almost all platforms: float-to-string and string-to-float
2781 conversions within Python are now correctly rounded. Places these conversions
2782 occur include: str for floats and complex numbers; the float and complex
2783 constructors; old-style and new-style numeric formatting; serialization and
2784 deserialization of floats and complex numbers using marshal, pickle and json;
2785 parsing of float and imaginary literals in Python code; Decimal-to-float
2786 conversion.
Mark Dickinsonb678de82009-11-19 18:41:49 +00002787
Georg Brandlba83f822010-03-14 09:50:54 +00002788 The conversions use a Python-adapted version of David Gay's well-known dtoa.c,
2789 providing correctly-rounded strtod and dtoa C functions. This code is
2790 supported on Windows, and on Unix-like platforms using gcc, icc or suncc as
2791 the C compiler. There may be a small number of platforms on which correct
2792 operation of this code cannot be guaranteed, so the code is not used: notably,
2793 this applies to platforms where the C double format is not IEEE 754 binary64,
2794 and to platforms on x86 hardware where the x87 FPU is set to 64-bit precision
2795 and Python's configure script is unable to determine how to change the FPU
2796 precision. On these platforms conversions use the platform strtod and dtoa,
2797 as before.
Mark Dickinsonb678de82009-11-19 18:41:49 +00002798
Georg Brandlba83f822010-03-14 09:50:54 +00002799- Issue #7117: Backport round implementation from Python 3.x. ``round()`` now
2800 uses the correctly-rounded string <-> float conversions described above (when
2801 available), and so produces correctly rounded results that will display nicely
2802 under the float repr. There are two related small changes: (1) round now
2803 accepts any class with an ``__index__()`` method for its second argument (but
2804 no longer accepts floats for the second argument), and (2) an excessively
2805 large second integer argument (e.g., ``round(1.234, 10**100)``) no longer
2806 raises an exception.

Georg Brandlba83f822010-03-14 09:50:54 +00002936- Issue #5829: complex("1e500") no longer raises OverflowError. This makes it
2937 consistent with float("1e500") and interpretation of real and imaginary
2938 literals.

Mark Dickinsonb1d45852009-05-11 15:33:08 +00002947- Issue #5981: Fix three minor inf/nan issues in float.fromhex:
Mark Dickinsonb1d45852009-05-11 15:33:08 +00002948
Georg Brandlba83f822010-03-14 09:50:54 +00002949 (1) inf and nan strings with trailing whitespace were incorrectly rejected;
2950 (2) parsing of strings representing infinities and nans was locale aware; and
2951 (3) the interpretation of fromhex('-nan') didn't match that of float('-nan').

Georg Brandlba83f822010-03-14 09:50:54 +00002953- Issue #5920: For ``float.__format__()``, change the behavior with the empty
2954 presentation type (that is, not one of 'e', 'f', 'g', or 'n') to be like 'g'
2955 but with at least one decimal point and with a default precision
2956 of 12. Previously, the behavior the same but with a default precision of 6.
2957 This more closely matches ``str()``, and reduces surprises when adding
2958 alignment flags to the empty presentation type. This also affects the new
2959 complex.__format__ in the same way.
2960
2961- Issue #5890: In subclasses of 'property' the __doc__ attribute was shadowed by
2962 classtype's, even if it was None. property now inserts the __doc__ into the

Antoine Pitrouf8387af2009-03-23 18:41:45 +00003023- Issue #4688: Add a heuristic so that tuples and dicts containing only
Georg Brandlba83f822010-03-14 09:50:54 +00003024 untrackable objects are not tracked by the garbage collector. This can reduce
3025 the size of collections and therefore the garbage collection overhead on

3033 internal representation of integers, for performance reasons. Base 2**30 is
3034 enabled by default on 64-bit machines. Add --enable-big-digits option to
3035 configure, which overrides the default. Add sys.long_info structseq to
3036 provide information about the internal format.

Georg Brandlba83f822010-03-14 09:50:54 +00003183- On windows, ``os.chdir()`` given unicode was not working if

3185 this code path is really executed because I cannot move to such directory on

Georg Brandlba83f822010-03-14 09:50:54 +00003188- Issue #4069: When ``set.remove(element)`` is used with a set element, the
3189 element is temporarily replaced with an equivalent frozenset. But the
3190 eventual KeyError would always report the empty ``frozenset()`` as the missing

Walter Dörwalded960ac2009-05-03 22:36:33 +00003211- Issue #5108: Handle %s like %S and %R in PyUnicode_FromFormatV(): Call
3212 PyUnicode_DecodeUTF8() once, remember the result and output it in a second
3213 step. This avoids problems with counting UTF-8 bytes that ignores the effect
3214 of using the replace error handler in PyUnicode_DecodeUTF8().
3215
Walter Dörwald726ba8e2009-05-06 14:32:35 +00003216- Issue #3739: The unicode-internal encoder now reports the number of characters

3218
Georg Brandlba83f822010-03-14 09:50:54 +00003219- Issue #2422: When compiled with the ``--with-valgrind`` option, the pymalloc
3220 allocator will be automatically disabled when running under Valgrind. This
3221 gives improved memory leak detection when running under Valgrind, while taking
3222 advantage of pymalloc at other times.

4388 'b', 'B', 'h', 'H', 'i', 'l', '*b', '*h' ,'*i', '*l', and an x with a
4389 __long__ method could be packed by 'q', 'Q', '*q', '*Q'; for x with
4390 neither __int__ nor __long__, TypeError used to be raised (with a
4391 confusing error message) for 'I', 'L', '*B', '*H', '*I', '*L', and
4392 struct.error in other cases.

4395 argument with an __int__ method can be packed, but use of this feature
4396 triggers a DeprecationWarning.

Martin v. Löwis9fa5a282008-09-11 06:53:30 +00004587- Issue #3642: Suppress warning in obmalloc when size_t is larger than uint.
4588
Amaury Forgeot d'Arc05e34492008-09-10 22:04:45 +00004589- Issue #3743: In a few places, PY_FORMAT_SIZE_T was incorrectly used with
4590 PyString_FromFormat or PyErr_Format to display size_t values. The macro
4591 PY_FORMAT_SIZE_T is designed to select the correct format for the OS
4592 ``printf`` function, whereas PyString_FromFormat has an independent
4593 implementation and uses "%zd" on all platforms for size_t values.
4594 This makes a difference on win64, where ``printf`` needs "%Id" to display
4595 64bit values.
4596
Benjamin Peterson97179b02008-09-09 20:55:01 +00004597- Issue #3634: _weakref.ref(Exception).__init__() gave invalid return value on
4598 error.
4599
Amaury Forgeot d'Arcd3ffb892008-09-09 07:24:30 +00004600- Issue #3777: long() applied to a float object now always return a long
4601 object; previously an int would be returned for small values. the __long__
4602 method is allowed to return either an int or a long, but the behaviour of
4603 float objects should not change to respect backward compatibility.
4604
Amaury Forgeot d'Arc3571fbf2008-09-01 19:52:00 +00004605- Issue #3751: str.rpartition would perform a left-partition when called with
4606 a unicode argument.
4607
Benjamin Peterson17f03ca2008-09-01 14:18:30 +00004608- Issue #3683: Fix compilation when --without-threads is given.

Vinay Sajip35e3b032008-09-01 14:33:59 +00004611 PyArg_ParseTuple and friends, which occurred when the argument for "s*"
Antoine Pitroud4ae97b2008-08-29 18:39:48 +00004612 was correctly parsed but parsing of subsequent arguments failed.
4613
Vinay Sajip35e3b032008-09-01 14:33:59 +00004614- Issue #2534: speed up isinstance() and issubclass() by 50-70%, so as to
Antoine Pitrou0668c622008-08-26 22:42:08 +00004615 match Python 2.5 speed despite the __instancecheck__ / __subclasscheck__
4616 mechanism. In the process, fix a bug where isinstance() and issubclass(),
4617 when given a tuple of classes as second argument, were looking up
4618 __instancecheck__ / __subclasscheck__ on the tuple rather than on each
4619 type object.
4620
Neal Norwitz18aa3882008-08-24 05:04:52 +00004621- Fix crashes on memory allocation failure found with failmalloc.

Brett Cannon1eaf0742008-09-02 01:25:16 +00004690 warnings.catch_warnings() along with some API cleanup. Expanding the tests
4691 for catch_warnings() also led to an improvement in the raising of a
4692 DeprecationWarning related to warnings.warn_explicit().

4764-----------------
4765
Guido van Rossumf8402962008-08-20 15:01:50 +00004766- Issue #1878: Remove Py_TPFLAGS_HAVE_VERSION_TAG from
4767 Py_TPFLAGS_DEFAULT when not building the core. This means 3rd party
4768 extensions do not automatically benefit from the class attribute
4769 cache; they will have to explicitly add Py_TPFLAGS_HAVE_VERSION_TAG
4770 to their tp_flags field if they care. This is a backwards
4771 compatibility feature; in 3.0, all types will use the cache by
4772 default.
4773
Benjamin Petersonf647dc12008-08-20 01:27:30 +00004774- Keyword arguments can now follow starred arguments. (``f(a, *args,
4775 keyword=23)`` is now valid syntax.)
4776
Thomas Heller0ad5ae02008-08-19 19:25:04 +00004777- ctypes function pointers that are COM methods have a boolean True
4778 value again.
4779
Martin v. Löwisf91d46a2008-08-12 14:49:50 +00004780- Issue #3139: Make buffer-interface thread-safe wrt. PyArg_ParseTuple,
4781 by denying s# to parse objects that have a releasebuffer procedure,
4782 and introducing s*.
4783
Georg Brandl1e13ea92008-08-11 09:07:59 +00004784- Issue #3537: Fix an assertion failure when an empty but presized dict
4785 object was stored in the freelist.
4786
Mark Dickinsonb6467572008-08-04 21:30:09 +00004787- Issue #1481296: Make long(float('nan')) and int(float('nan')) raise
4788 ValueError consistently across platforms.
4789
Amaury Forgeot d'Arc39fd6722008-07-31 21:28:03 +00004790- Issue #3479: On platforms where sizeof(int) is smaller than sizeof(long)
4791 (64bit Unix, for example), unichr() would truncate its argument and return
4792 u'\x00' for unichr(2**32). Now it properly raises an OverflowError.
4793
Neal Norwitze7d8be82008-07-31 17:17:14 +00004794- Apply security patches from Apple.
4795
Amaury Forgeot d'Arc246daed2008-07-31 00:42:16 +00004796- Issue #2542: Now that issubclass() may call arbitrary code, ensure that
4797 PyErr_ExceptionMatches returns 0 when an exception occurs there.
4798
Antoine Pitrou92f82162008-07-25 22:22:08 +00004799- Issue #1819: function calls with several named parameters are now on
4800 average 35% faster (as measured by pybench).
4801
Amaury Forgeot d'Arce4921fe2008-07-21 22:00:38 +00004802- Issue #2378: An unexpected UnboundLocalError or NameError could appear when
4803 the python debugger steps into a class statement: the free variables (local
4804 variables defined in an outer scope) would be deleted from the outer scope.
4805
Gregory P. Smith0470bab2008-07-22 04:46:32 +00004806- Issue #2620: Overflow checking when allocating or reallocating memory
4807 was not always being done properly in some python types and extension
4808 modules. PyMem_MALLOC, PyMem_REALLOC, PyMem_NEW and PyMem_RESIZE have
4809 all been updated to perform better checks and places in the code that
4810 would previously leak memory on the error path when such an allocation
4811 failed have been fixed.

4815
Hirokazu Yamamoto838c79f2008-08-20 13:14:07 +00004816- Issue #3612: Added some missing basic types in ctypes.wintypes.
4817
Benjamin Petersone977ad42008-08-20 01:42:01 +00004818- The methods ``is_in_tuple()``, ``is_vararg()``, and ``is_keywordarg()`` of
4819 symtable.Symbol have been deprecated for removal in 3.0 and the next release.
4820
Amaury Forgeot d'Arc351ffb82008-08-18 19:23:47 +00004821- Issue #2234: distutils failed for some versions of the cygwin compiler. The
4822 version reported by these tools does not necessarily follow the python
4823 version numbering scheme, so the module is less strict when parsing it.
4824
Nick Coghlanf70385a2008-08-18 12:42:46 +00004825- Issue #2235: Added Py3k warnings for types which will become unhashable
4826 under the stricter __hash__ inheritance rules in 3.0. Several types
4827 which did not meet the rules for hash invariants and were already
4828 unhashable in 3.0 have now been explicitly flagged as unhashable in
4829 2.6 as well (collections.Mapping, collections.Set, unittest.TestSuite,
4830 xml.dom.minidom.NamedNodeMap, numbers.Number, UserList.UserList)
4831
Brett Cannon88f801d2008-08-18 00:46:22 +00004832- Update __all__ for cookielib, csv, os, urllib2, and weakref to include things

4958-----------------
4959
Georg Brandl3e483f62008-07-16 22:57:41 +00004960- Issue #3156: Fix inconsistent behavior of the bytearray type: all
4961 its methods now allow for items objects that can be converted to
4962 an integer using operator.index().
4963
Mark Dickinson64b7e502008-07-16 09:40:03 +00004964- Issue #3360: Fix incorrect parsing of '020000000000.0', which
4965 produced a ValueError instead of giving the correct float.
4966
Eric Smitha5fa5a22008-07-16 00:11:49 +00004967- Issue #3083: Add alternate (#) formatting for bin, oct, hex output
4968 for str.format(). This adds the prefix 0b, 0o, or 0x, respectively.
4969
Mark Dickinson7103aa42008-07-15 19:08:33 +00004970- Issue #3008: the float type has a new instance method 'float.hex'
4971 and a new class method 'float.fromhex' to convert floating-point
4972 numbers to and from hexadecimal strings, respectively.
4973
Nick Coghlan6d6bd442008-07-15 15:40:22 +00004974- Issue #2235: __hash__ is once again inherited by default. To allow
4975 collections.Hashable to remain meaningful in the presence of the
4976 default hash implementation (object.__hash__), it is now possible
4977 to explicit block inheritance of hash by setting __hash__=None at
4978 the Python level, or tp_hash=PyObject_HashNotImplemented at the C
4979 level.
4980
Nick Coghlanb028f502008-07-13 14:52:36 +00004981- Issue #3221: Issue a RuntimeWarning instead of raising SystemError if
4982 the parent module cannot be found while performing an absolute import.
4983 This means that an incorrectly defined __package__ attribute will
4984 now only prevent relative imports in that module rather than causing
4985 all imports from that module to fail.
4986
Nick Coghlan14ff9942008-07-08 14:21:42 +00004987- Issue #2517: Allow unicode messages in Exceptions again by correctly

4997 another thread's dictionary.
4998
Mark Dickinson1ec2fcd2008-06-20 14:53:43 +00004999- Issue #3004: Minor change to slice.indices(): the start and stop
5000 arguments are now treated identically, making the behaviour easier
5001 to describe and understand. For example, slice(None, -10,
5002 1).indices(9) now returns (0, 0, 1) instead of (0, -1, 1), and
5003 slice(None, 10, -1).indices(10) returns (9, 9, -1) instead of (9,
5004 10, -1).
5005
Georg Brandl278fc502008-07-19 12:46:12 +00005006- Issue #3219: Calling a function with repeated keyword arguments,
5007 f(a=2, a=23), would not cause a syntax error. This was a regression
5008 from 2.4 caused by the switch to the new compiler.

5047 both unnecessary (HTTP allows text content to be sent in several forms) and
Andrew M. Kuchlingcc3f2b12008-07-10 14:43:31 +00005048 wrong because the actual transmitted size could differ from the
Amaury Forgeot d'Arc0f7cddc2008-07-06 21:34:39 +00005049 content-length. The problem had been corrected in the 2.4 branch, but never

5457 mode or even as a 4-way universal binary (that is, PPC, i386,
Georg Brandl5cc774e2008-06-11 20:28:06 +00005458 PPC64 and x86_64 support in one binary).
Ronald Oussoren5640ce22008-06-05 12:58:24 +00005459
5460 This is controlled by the configure argument ``--with-universal-archs``:
5461
5462 - ``--with-universal-archs=all``: install 4-way universal
5463
5464 - ``--with-universal-archs=32-bit``: install 2-way universal, 32-bit (the default)
5465
5466 - ``--with-universal-archs=64-bit``: install 2-way universal, 64-bit
5467
5468 This option should be used in combination with ``--enable-universalsdk=``.
5469
5470 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 +00005520- Issue #1631171: Re-implement the 'warnings' module in C (the
5521 original Python code has been kept as backup). This will allow for
5522 using the 'warning's machinery in such places as the parser where
5523 use of pure Python code is not possible. Both the ``showarning()``
5524 and ``formatwarning()`` gain an optional 'line' argument which is
5525 not called by default for backwards-compatibility reasons. Setting
5526 ``warnings.showwarning()`` to an implementation that lacks support
5527 for the ``line`` argument will raise a DeprecationWarning.

Georg Brandl3ee81df2008-05-17 18:14:43 +00005590- Issue #2550: The approach used by client/server code for obtaining
5591 ports to listen on in network-oriented tests has been refined in an
5592 effort to facilitate running multiple instances of the entire
5593 regression test suite in parallel without issue.
5594 test_support.bind_port() has been fixed such that it will always
5595 return a unique port -- which wasn't always the case with the
5596 previous implementation, especially if socket options had been set
5597 that affected address reuse (i.e. SO_REUSEADDR, SO_REUSEPORT). The
5598 new implementation of bind_port() will actually raise an exception
5599 if it is passed an AF_INET/SOCK_STREAM socket with either the
5600 SO_REUSEADDR or SO_REUSEPORT socket option set. Furthermore, if
5601 available, bind_port() will set the SO_EXCLUSIVEADDRUSE option on
5602 the socket it's been passed. This currently only applies to
5603 Windows. This option prevents any other sockets from binding to the
5604 host/port we've bound to, thus removing the possibility of the
5605 'non-deterministic' behaviour, as Microsoft puts it, that occurs
5606 when a second SOCK_STREAM socket binds and accepts to a host/port
5607 that's already been bound by another socket. The optional preferred
5608 port parameter to bind_port() has been removed. Under no
5609 circumstances should tests be hard coding ports!
5610
5611 test_support.find_unused_port() has also been introduced, which will
5612 pass a temporary socket object to bind_port() in order to obtain an
5613 unused port. The temporary socket object is then closed and
5614 deleted, and the port is returned. This method should only be used
5615 for obtaining an unused port in order to pass to an external program
5616 (i.e. the -accept [port] argument to openssl's s_server mode) or as
5617 a parameter to a server-oriented class that doesn't give you direct
5618 access to the underlying socket used.
5619
5620 Finally, test_support.HOST has been introduced, which should be used
5621 for the host argument of any relevant socket calls (i.e. bind and
5622 connect).
Trent Nelsone41b0062008-04-08 23:47:30 +00005623
5624 The following tests were updated to following the new conventions:
Georg Brandl3ee81df2008-05-17 18:14:43 +00005625 test_socket, test_smtplib, test_asyncore, test_ssl, test_httplib,
Trent Nelsone41b0062008-04-08 23:47:30 +00005626 test_poplib, test_ftplib, test_telnetlib, test_socketserver,
5627 test_asynchat and test_socket_ssl.
5628
Georg Brandl3ee81df2008-05-17 18:14:43 +00005629 It is now possible for multiple instances of the regression test
5630 suite to run in parallel without issue.

Amaury Forgeot d'Arc9a0d3462008-03-23 09:55:29 +00005684- Issue #1477: With narrow Unicode builds, the unicode escape sequence
Georg Brandl3ee81df2008-05-17 18:14:43 +00005685 \Uxxxxxxxx did not accept values outside the Basic Multilingual
5686 Plane. This affected raw unicode literals and the
5687 'raw-unicode-escape' codec. Now UTF-16 surrogates are generated in
5688 this case, like normal unicode literals and the 'unicode-escape'
5689 codec.

Eric Smitha73fbe72008-02-23 03:09:44 +00005909- Added the future_builtins module, which contains hex() and oct().
5910 These are the PEP 3127 version of these functions, designed to be
5911 compatible with the hex() and oct() builtins from Python 3.0. They
5912 differ slightly in their output formats from the existing, unchanged
5913 Python 2.6 builtins. The expected usage of the future_builtins
5914 module is:
5915 from future_builtins import hex, oct
5916
Eric Smith7ef40bf2008-02-20 23:34:22 +00005917- Issue #1600: Modifed PyOS_ascii_formatd to use at most 2 digit
5918 exponents for exponents with absolute value < 100. Follows C99
5919 standard. This is a change on Windows, which would use 3 digits.
5920 Also, added 'n' to the formats that PyOS_ascii_formatd understands,
5921 so that any alterations it does to the resulting string will be
5922 available in stringlib/formatter.h (for float.__format__).
5923
Eric Smith5a3c1352008-02-19 13:21:56 +00005924- Implemented PEP 3101, Advanced String Formatting. This adds a new
5925 builtin format(); a format() method for str and unicode; a
5926 __format__() method to object, str, unicode, int, long, float, and
5927 datetime; the class string.Formatter; and the C API
5928 PyObject_Format().
5929
Georg Brandl3ee81df2008-05-17 18:14:43 +00005930- Fixed several potential crashes, all caused by specially crafted
5931 __del__ methods exploiting objects in temporarily inconsistent
5932 state.
Amaury Forgeot d'Arc632fad32008-02-16 20:55:24 +00005933
Vinay Sajipb7edfc42008-04-02 21:10:23 +00005934- Issue #2115: Important speedup in setting __slot__ attributes. Also
Georg Brandl3ee81df2008-05-17 18:14:43 +00005935 prevent a possible crash: an Abstract Base Class would try to access
5936 a slot on a registered virtual subclass.
Amaury Forgeot d'Arc60d6c7f2008-02-15 21:22:45 +00005937

Georg Brandl3ee81df2008-05-17 18:14:43 +00005941- Clear all free lists during a gc.collect() of the highest generation
5942 in order to allow pymalloc to free more arenas. Python may give back
5943 memory to the OS earlier.
Christian Heimes3b718a72008-02-14 12:47:33 +00005944
Georg Brandl3ee81df2008-05-17 18:14:43 +00005945- Issue #2045: Fix an infinite recursion triggered when printing a

Georg Brandl3ee81df2008-05-17 18:14:43 +00005975- Patch #1473257: generator objects gain a gi_code attribute. This is
5976 the same object as the func_code attribute of the function that
5977 produced the generator.
Georg Brandl0cdf9a32008-01-26 14:14:20 +00005978
Georg Brandl3ee81df2008-05-17 18:14:43 +00005979- Issue #1920: "while 0" statements were completely removed by the
5980 compiler, even in the presence of an "else" clause, which is
5981 supposed to be run when the condition is false. Now the compiler
5982 correctly emits bytecode for the "else" suite.
Amaury Forgeot d'Arc31eaafe2008-01-24 22:59:25 +00005983
Guido van Rossumeead05f2008-01-24 18:21:02 +00005984- A few crashers fixed: weakref_in_del.py (issue #1377858);

5991
Georg Brandl3ee81df2008-05-17 18:14:43 +00005992- Issue #1915: Python compiles with --enable-unicode=no again. However
Christian Heimes082c9b02008-01-23 14:20:50 +00005993 several extension methods and modules do not work without unicode
5994 support.
5995

6000
Georg Brandl6caad7d2008-01-26 14:19:22 +00006001- Issue #1865: ``bytes`` as an alias for ``str`` and b"" as an alias "" were
Christian Heimes288e89a2008-01-18 18:24:07 +00006002 added.
6003
Christian Heimesc94e2b52008-01-14 04:13:37 +00006004- sys.float_info / PyFloat_GetInfo: The floating point information
6005 object was converted from a dict to a specialized structseq object.
6006
Georg Brandl3ee81df2008-05-17 18:14:43 +00006007- Patch #1816: Added sys.flags structseq. It exposes the status of
6008 most command line arguments and PYTHON* environment variables.
Christian Heimesf31b69f2008-01-14 03:42:48 +00006009
Georg Brandl3ee81df2008-05-17 18:14:43 +00006010- Objects/structseq.c: Implemented new structseq representation. The
6011 patch makes structseqs (e.g. the return value of os.stat) more
6012 readable.
Christian Heimes9c201962008-01-14 03:33:52 +00006013
Georg Brandl3ee81df2008-05-17 18:14:43 +00006014- Patch #1700288: added a type attribute cache that caches method
6015 accesses, resulting in speedups in heavily object-oriented code.
Amaury Forgeot d'Arce4c270c2008-01-14 00:29:41 +00006016
Neal Norwitz3fc15b82008-01-10 05:42:58 +00006017- Bug #1776: __import__() no longer accepts filenames on any platform.

6023 envvar and sys.dont_write_bytecode attribute. All these can be set
6024 to forbid Python to attempt to write compiled bytecode files.
Georg Brandl2da0fce2008-01-07 17:09:35 +00006025
Georg Brandl3ee81df2008-05-17 18:14:43 +00006026- Improve some exception messages when Windows fails to load an
6027 extension module. Now we get for example '%1 is not a valid Win32
6028 application' instead of 'error code 193'.

6085
Georg Brandl21e99f42010-03-07 15:23:59 +00006086- The enumerate() built-in function is no longer bounded to sequences
Georg Brandl3ee81df2008-05-17 18:14:43 +00006087 smaller than LONG_MAX. Formerly, it raised an OverflowError. Now,
6088 automatically shifts from ints to longs.
Raymond Hettinger8f669372007-10-03 21:18:11 +00006089
Georg Brandl3ee81df2008-05-17 18:14:43 +00006090- Issue #1686386: Tuple's tp_repr did not take into account the
6091 possibility of having a self-referential tuple, which is possible
6092 from C code. Nor did object's tp_str consider that a type's tp_str
6093 could do something that could lead to an inifinite recursion.
6094 Py_ReprEnter() and Py_EnterRecursiveCall(), respectively, fixed the
6095 issues.
Brett Cannon0b14f242007-09-30 19:45:10 +00006096

6098 'print' statement to write to a file since the GIL was not released
6099 as needed. Now PyObject_Print() does the right thing along with
6100 various tp_print implementations of the built-in types and those in
6101 the collections module.
Brett Cannon01531592007-09-17 03:28:34 +00006102

Georg Brandl3ee81df2008-05-17 18:14:43 +00006111 PyObject_Call() never calling back out to Python code to trigger
6112 recursion depth updates/checks. Required the creation of a static
6113 RuntimeError instance in case normalizing an exception put the
6114 recursion check value past its limit. Fixes crashers

Guido van Rossum143b5642007-03-23 04:58:42 +00006163- Bug #1683368: The object.__init__() and object.__new__() methods are
6164 now stricter in rejecting excess arguments. The only time when
6165 either allows excess arguments is when it is not overridden and the
6166 other one is. For backwards compatibility, when both are
6167 overridden, it is a deprecation warning (for now; maybe a Py3k
Guido van Rossum234b1ff2007-03-23 19:39:01 +00006168 warning later). Also, type.__init__() insists on the same signature
6169 as supported by type.__new__().

Georg Brandl3ee81df2008-05-17 18:14:43 +00006171- Patch #1675423: PyComplex_AsCComplex() now tries to convert an
6172 object to complex using its __complex__() method before falling back
6173 to the __float__() method. Therefore, the functions in the cmath
6174 module now can operate on objects that define a __complex__()
6175 method.

Georg Brandl7b9c5552007-03-12 14:30:05 +00006193- Bug #1678647: write a newline after printing an exception in any
6194 case, even when converting the value to a string failed.
6195
Georg Brandl871f1bc2007-03-12 13:17:36 +00006196- The dir() function has been extended to call the __dir__() method on
Georg Brandl3ee81df2008-05-17 18:14:43 +00006197 its argument, if it exists. If not, it will work like before. This
6198 allows customizing the output of dir() in the presence of a
6199 __getattr__().

6209 raising a ValueError.
Collin Wintere38051d2007-03-09 20:33:07 +00006210
Georg Brandlaa2321b2007-03-07 00:40:28 +00006211- Patch #703779: unset __file__ in __main__ after running a file. This
Georg Brandl3ee81df2008-05-17 18:14:43 +00006212 makes the filenames the warning module prints much more sensible
6213 when a PYTHONSTARTUP file is used.

Georg Brandl0fca97a2007-03-05 22:28:08 +00006226- Patch #1674228: when assigning a slice (old-style), check for the
6227 sq_ass_slice instead of the sq_slice slot.
6228
Georg Brandl3ee81df2008-05-17 18:14:43 +00006229- When printing an unraisable error, don't print exceptions. before
6230 the name. This duplicates the behavior whening normally printing
6231 exceptions.

Georg Brandl2c1375c2006-10-12 11:27:59 +00006281- Bug #1545497: when given an explicit base, int() did ignore NULs
6282 embedded in the string to convert.
6283
Georg Brandl846f73a2006-10-08 07:11:54 +00006284- Bug #1569998: break inside a try statement (outside a loop) is now

Neal Norwitzdac090d2006-09-05 03:53:08 +00006331- Bug #1520864: unpacking singleton tuples in list comprehensions and
Georg Brandl3ee81df2008-05-17 18:14:43 +00006332 generator expressions (x for x, in ... ) works again. Fixing this
6333 problem required changing the .pyc magic number. This means that
6334 .pyc files generated before 2.5c2 will be regenerated.

6737
Vinay Sajip8549ce32007-05-06 17:53:37 +00006738- Patch #1676823: Added create_connection() to socket.py, which may be

Georg Brandl3ee81df2008-05-17 18:14:43 +00006764 AttributeError instead of an IOError when the server's response
6765 didn't contain a valid HTTP status line.

6856 TestCase and TestSuite subclasses (not instances) are no longer
6857 accepted in TestSuite.addTest(). This should cause no
6858 incompatibility since it never made sense with ordinary subclasses
6859 -- the failure just occurred later, with a more cumbersome
6860 exception.

Georg Brandl3ee81df2008-05-17 18:14:43 +00007137- The implementation of UnicodeError objects has been simplified
7138 (start and end attributes are now stored directly as Py_ssize_t
7139 members).

Georg Brandl3ee81df2008-05-17 18:14:43 +00007141- Issue #829951: In the smtplib module, SMTP.starttls() now complies
7142 with RFC 3207 and forgets any knowledge obtained from the server not
7143 obtained from the TLS negotiation itself. Patch contributed by Bill
7144 Fenner.
Gregory P. Smith2b3ba582008-01-17 08:03:17 +00007145
Georg Brandl3ee81df2008-05-17 18:14:43 +00007146- Issue #1339: The smtplib.SMTP class has been refactored a bit such
Gregory P. Smithbde4ae42008-01-17 08:35:49 +00007147 that the SMTP.starttls() caller no longer needs to call ehlo()
7148 beforehand. SMTP.starttls() now raises an exception of the server
Georg Brandl3ee81df2008-05-17 18:14:43 +00007149 does not claim to support starttls. Adds the
7150 SMTP.ehlo_or_helo_if_needed() method. Patch contributed by Bill
7151 Fenner.

7220 contents before adding elements from the iterable. This fix brings
7221 the behavior into line with that for list.__init__().
Raymond Hettingeradf9ffd2007-12-13 00:08:37 +00007222
Georg Brandl3ee81df2008-05-17 18:14:43 +00007223- Added wide char functions to msvcrt module: getwch, getwche, putwch

7231 complex, tuple, list, dict, set, and frozenset. Formerly, it would
7232 silently miscode subclasses of those types. Now, it raises a
7233 ValueError instead.
Raymond Hettinger12e94202007-11-07 01:13:09 +00007234

Georg Brandl3ee81df2008-05-17 18:14:43 +00007249 time so that opening a database previously created with the DB_DUP
7250 or DB_DUPSORT flag set will keep the proper behavior on subsequent
7251 opens. Specifically: dictionary assignment to a DB object will
7252 replace all values for a given key when the database allows
7253 duplicate values. DB users should use DB.put(k, v) when they want
7254 to store duplicates; not DB[k] = v.
Gregory P. Smithec10a4a2007-11-05 02:32:26 +00007255

7261 characters with ASCII value less than 32. Also, it correctly quotes
7262 dots only if they occur on a single line, as opposed to the previous
7263 behavior of quoting dots if they are the second character of any
7264 line.
Georg Brandl4aef7272007-03-13 22:49:43 +00007265

7655 builds.

Georg Brandl3ee81df2008-05-17 18:14:43 +00007670- Removed the macfs module. It had been deprecated since Python 2.5.
7671 This lead to the deprecation of macostools.touched() as it relied
7672 solely on macfs and was a no-op under OS X.
