Mark Dickinsondbbed042011-09-19 16:38:08 +0100609- Issue #12973: Fix overflow checks that invoked undefined behaviour in
610 int.__pow__. These overflow checks were causing int.__pow__ to produce
611 incorrect results with recent versions of Clang, as a result of the
Mark Dickinsona96b0d12011-09-24 09:01:16 +0100612 compiler optimizing the check away. Also fix similar overflow checks
613 in list_repeat (listobject.c) and islice_next (itertoolsmodule.c). These
614 bugs caused test failures with recent versions of Clang.

Ned Deilyc47a4592012-02-11 20:40:24 +0100683 has left two versions of customize_compiler, the original in
684 distutils.sysconfig and another copy in distutils.ccompiler, with some

Ned Deily0d0ea482012-02-10 12:59:06 +0100689- Issue #13590: On OS X 10.7 and 10.6 with Xcode 4.2, building
690 Distutils-based packages with C extension modules may fail because
691 Apple has removed gcc-4.2, the version used to build python.org
692 64-bit/32-bit Pythons. If the user does not explicitly override
693 the default C compiler by setting the CC environment variable,
694 Distutils will now attempt to compile extension modules with clang
695 if gcc-4.2 is required but not found. Also as a convenience, if
696 the user does explicitly set CC, substitute its value as the default
697 compiler in the Distutils LDSHARED configuration variable for OS X.
698 (Note, the python.org 32-bit-only Pythons use gcc-4.0 and the 10.4u
699 SDK, neither of which are available in Xcode 4. This change does not
700 attempt to override settings to support their use with Xcode 4.)

Ned Deily87e82bb2011-06-28 19:52:59 -0700973- Issue #9516: On Mac OS X, change Distutils to no longer globally attempt to
974 check or set the MACOSX_DEPLOYMENT_TARGET environment variable for the
975 interpreter process. This could cause failures in non-Distutils subprocesses
976 and was unreliable since tests or user programs could modify the interpreter
977 environment after Distutils set it. Instead, have Distutils set the the
978 deployment target only in the environment of each build subprocess. It is
979 still possible to globally override the default by setting
980 MACOSX_DEPLOYMENT_TARGET before launching the interpreter; its value must be
981 greater or equal to the default value, the value with which the interpreter
982 was built.

1009
Barry Warsawc5643282011-07-19 17:06:30 -04001010- sys.setcheckinterval() now updates the current ticker count as well as
1011 updating the check interval, so if the user decreases the check interval,
1012 the ticker doesn't have to wind down to zero from the old starting point
1013 before the new interval takes effect. And if the user increases the
1014 interval, it makes sure the new limit takes effect right away rather have an
1015 early task switch before recognizing the new interval.

1965
Raymond Hettinger20397532010-09-12 02:11:45 +00001966- Issue #9825: removed __del__ from the definition of collections.OrderedDict.
1967 This prevents user-created self-referencing ordered dictionaries from
1968 becoming permanently uncollectable GC garbage. The downside is that
1969 removing __del__ means that the internal doubly-linked list has to wait for
1970 GC collection rather than freeing memory immediately when the refcnt drops
1971 to zero.

1976
Antoine Pitrouc818ed42010-09-07 21:40:25 +00001977- Issue #9792: In case of connection failure, socket.create_connection()

1979 to fetch the original errno, or to filter timeout errors. Now the
1980 original error is re-raised.

2429
Ezio Melottiab2eb0e2010-06-05 19:21:32 +00002430- Issue #8271: during the decoding of an invalid UTF-8 byte sequence, only the
2431 start byte and the continuation byte(s) are now considered invalid, instead
2432 of the number of bytes specified by the start byte.
2433 E.g.: '\xf1\x80AB'.decode('utf-8', 'replace') now returns u'\ufffdAB' and
2434 replaces with U+FFFD only the start byte ('\xf1') and the continuation byte
2435 ('\x80') even if '\xf1' is the start byte of a 4-bytes sequence.
2436 Previous versions returned a single u'\ufffd'.

2440 arises from the "Overriding __eq__ blocks inheritance ..." warning
2441 when turned into an exception: in this case the exception simply
2442 gets ignored.
Mark Dickinson23f0d6b2010-06-05 11:52:24 +00002443
Mark Dickinson4ca7c3c2010-05-30 13:18:10 +00002444- Issue #8748: Fix two issues with comparisons between complex and integer
2445 objects. (1) The comparison could incorrectly return True in some cases
2446 (2**53+1 == complex(2**53) == 2**53), breaking transivity of equality.
2447 (2) The comparison raised an OverflowError for large integers, leading
2448 to unpredictable exceptions when combining integers and complex objects
2449 in sets or dicts.
2450
Mark Dickinson81336372010-05-30 12:12:25 +00002451- Issue #5211: Implicit coercion for the complex type is now completely
2452 removed. (Coercion for arithmetic operations was already removed in 2.7

Victor Stinnerc49dfcc2010-05-25 22:30:32 +00002455- Issue #3798: Write sys.exit() message to sys.stderr to use stderr encoding

2832 with a non-empty format string. This is an effort to future-proof user

Georg Brandlba83f822010-03-14 09:50:54 +00003329 file position when calling `truncate()`. It would previously change the file
3330 position to the given argument, which goes against the tradition of

3334 class used to represent files stored inside an archive. The new
3335 implementation is significantly faster and can be wrapped in a
3336 ``io.BufferedReader`` object for more speedups. It also solves an issue
3337 where interleaved calls to ``read()`` and ``readline()`` give wrong results.

3426-----------------
3427
Georg Brandlba83f822010-03-14 09:50:54 +00003428- The ``__complex__()`` method is now looked up on the class of instances to
3429 make it consistent with other special methods.

3433
Mark Dickinson1b34d252010-01-01 17:27:30 +00003434- Issue #5080: A number of functions and methods previously produced a
Georg Brandlba83f822010-03-14 09:50:54 +00003435 DeprecationWarning when passed a float argument where an integer was expected.
3436 These functions and methods now raise TypeError instead. The majority of the
3437 effects of this change are in the extension modules, but some core functions
3438 and methods are affected: notably the 'chr', 'range' and 'xrange' builtins,
3439 and many unicode/str methods.

3454 least on IEEE 754 platforms), and in particular does not depend on the
3455 internal representation of a long.

3463
Georg Brandlba83f822010-03-14 09:50:54 +00003464 These executables now work properly with the arch(1) command: ``arch -ppc

3552 ``PyArg_ParseTupleAndKeywords()``, ``PyArg_VaParse()``,
3553 ``PyArg_VaParseTupleAndKeywords()`` and ``PyArg_Parse()`` no longer accept
3554 float arguments for integer format codes (other than 'L'): previously an
3555 attempt to pass a float resulted in a DeprecationWarning; now it gives a
3556 TypeError. For the 'L' format code (which previously had no warning) there is
3557 now a DeprecationWarning.

3606 to 'g' for large values.
Amaury Forgeot d'Arcd7288712009-12-01 21:51:04 +00003607

3609 1e50 in absolute value.

3613 significant digits instead.

Georg Brandlba83f822010-03-14 09:50:54 +00003622- Issue #7117: ``repr(x)`` for a float x returns a result based on the shortest
3623 decimal string that's guaranteed to round back to x under correct rounding
3624 (with round-half-to-even rounding mode). Previously it gave a string based on
3625 rounding x to 17 decimal digits. repr(x) for a complex number behaves
3626 similarly. On platforms where the correctly-rounded strtod and dtoa code is
3627 not supported (see below), repr is unchanged.
Mark Dickinsonb678de82009-11-19 18:41:49 +00003628
Georg Brandlba83f822010-03-14 09:50:54 +00003629- Issue #7117: On almost all platforms: float-to-string and string-to-float
3630 conversions within Python are now correctly rounded. Places these conversions
3631 occur include: str for floats and complex numbers; the float and complex
3632 constructors; old-style and new-style numeric formatting; serialization and
3633 deserialization of floats and complex numbers using marshal, pickle and json;
3634 parsing of float and imaginary literals in Python code; Decimal-to-float
3635 conversion.
Mark Dickinsonb678de82009-11-19 18:41:49 +00003636
Georg Brandlba83f822010-03-14 09:50:54 +00003637 The conversions use a Python-adapted version of David Gay's well-known dtoa.c,
3638 providing correctly-rounded strtod and dtoa C functions. This code is
3639 supported on Windows, and on Unix-like platforms using gcc, icc or suncc as
3640 the C compiler. There may be a small number of platforms on which correct
3641 operation of this code cannot be guaranteed, so the code is not used: notably,
3642 this applies to platforms where the C double format is not IEEE 754 binary64,
3643 and to platforms on x86 hardware where the x87 FPU is set to 64-bit precision
3644 and Python's configure script is unable to determine how to change the FPU
3645 precision. On these platforms conversions use the platform strtod and dtoa,
3646 as before.
Mark Dickinsonb678de82009-11-19 18:41:49 +00003647
Georg Brandlba83f822010-03-14 09:50:54 +00003648- Issue #7117: Backport round implementation from Python 3.x. ``round()`` now
3649 uses the correctly-rounded string <-> float conversions described above (when
3650 available), and so produces correctly rounded results that will display nicely
3651 under the float repr. There are two related small changes: (1) round now
3652 accepts any class with an ``__index__()`` method for its second argument (but
3653 no longer accepts floats for the second argument), and (2) an excessively
3654 large second integer argument (e.g., ``round(1.234, 10**100)``) no longer
3655 raises an exception.

Georg Brandlba83f822010-03-14 09:50:54 +00003785- Issue #5829: complex("1e500") no longer raises OverflowError. This makes it
3786 consistent with float("1e500") and interpretation of real and imaginary
3787 literals.

Mark Dickinsonb1d45852009-05-11 15:33:08 +00003796- Issue #5981: Fix three minor inf/nan issues in float.fromhex:
Mark Dickinsonb1d45852009-05-11 15:33:08 +00003797
Georg Brandlba83f822010-03-14 09:50:54 +00003798 (1) inf and nan strings with trailing whitespace were incorrectly rejected;
3799 (2) parsing of strings representing infinities and nans was locale aware; and
3800 (3) the interpretation of fromhex('-nan') didn't match that of float('-nan').

Georg Brandlba83f822010-03-14 09:50:54 +00003802- Issue #5920: For ``float.__format__()``, change the behavior with the empty
3803 presentation type (that is, not one of 'e', 'f', 'g', or 'n') to be like 'g'
3804 but with at least one decimal point and with a default precision
3805 of 12. Previously, the behavior the same but with a default precision of 6.
3806 This more closely matches ``str()``, and reduces surprises when adding
3807 alignment flags to the empty presentation type. This also affects the new
3808 complex.__format__ in the same way.
3809
3810- Issue #5890: In subclasses of 'property' the __doc__ attribute was shadowed by
3811 classtype's, even if it was None. property now inserts the __doc__ into the

Georg Brandlba83f822010-03-14 09:50:54 +00003873 untrackable objects are not tracked by the garbage collector. This can reduce
3874 the size of collections and therefore the garbage collection overhead on

3882 internal representation of integers, for performance reasons. Base 2**30 is
3883 enabled by default on 64-bit machines. Add --enable-big-digits option to
3884 configure, which overrides the default. Add sys.long_info structseq to
3885 provide information about the internal format.

Georg Brandlba83f822010-03-14 09:50:54 +00004032- On windows, ``os.chdir()`` given unicode was not working if

4034 this code path is really executed because I cannot move to such directory on
4035 win2k)

Georg Brandlba83f822010-03-14 09:50:54 +00004037- Issue #4069: When ``set.remove(element)`` is used with a set element, the
4038 element is temporarily replaced with an equivalent frozenset. But the
4039 eventual KeyError would always report the empty ``frozenset()`` as the missing
4040 key. Now it correctly refers to the initial element.

Walter Dörwalded960ac2009-05-03 22:36:33 +00004060- Issue #5108: Handle %s like %S and %R in PyUnicode_FromFormatV(): Call
4061 PyUnicode_DecodeUTF8() once, remember the result and output it in a second
4062 step. This avoids problems with counting UTF-8 bytes that ignores the effect
4063 of using the replace error handler in PyUnicode_DecodeUTF8().
4064
Walter Dörwald726ba8e2009-05-06 14:32:35 +00004065- Issue #3739: The unicode-internal encoder now reports the number of characters

4067
Georg Brandlba83f822010-03-14 09:50:54 +00004068- Issue #2422: When compiled with the ``--with-valgrind`` option, the pymalloc
4069 allocator will be automatically disabled when running under Valgrind. This
4070 gives improved memory leak detection when running under Valgrind, while taking
4071 advantage of pymalloc at other times.

Georg Brandlba83f822010-03-14 09:50:54 +00005235 - If x is not an int, long or float, then packing x will always result in
5236 struct.error. Previously an x with an __int__ method could be packed by
5237 'b', 'B', 'h', 'H', 'i', 'l', '*b', '*h' ,'*i', '*l', and an x with a
5238 __long__ method could be packed by 'q', 'Q', '*q', '*Q'; for x with
5239 neither __int__ nor __long__, TypeError used to be raised (with a
5240 confusing error message) for 'I', 'L', '*B', '*H', '*I', '*L', and
5241 struct.error in other cases.

5244 argument with an __int__ method can be packed, but use of this feature
5245 triggers a DeprecationWarning.

Martin v. Löwis9fa5a282008-09-11 06:53:30 +00005436- Issue #3642: Suppress warning in obmalloc when size_t is larger than uint.
5437
Amaury Forgeot d'Arc05e34492008-09-10 22:04:45 +00005438- Issue #3743: In a few places, PY_FORMAT_SIZE_T was incorrectly used with
5439 PyString_FromFormat or PyErr_Format to display size_t values. The macro
5440 PY_FORMAT_SIZE_T is designed to select the correct format for the OS
5441 ``printf`` function, whereas PyString_FromFormat has an independent
5442 implementation and uses "%zd" on all platforms for size_t values.
5443 This makes a difference on win64, where ``printf`` needs "%Id" to display
5444 64bit values.
5445
Benjamin Peterson97179b02008-09-09 20:55:01 +00005446- Issue #3634: _weakref.ref(Exception).__init__() gave invalid return value on
5447 error.
5448
Amaury Forgeot d'Arcd3ffb892008-09-09 07:24:30 +00005449- Issue #3777: long() applied to a float object now always return a long
5450 object; previously an int would be returned for small values. the __long__
5451 method is allowed to return either an int or a long, but the behaviour of
5452 float objects should not change to respect backward compatibility.
5453
Amaury Forgeot d'Arc3571fbf2008-09-01 19:52:00 +00005454- Issue #3751: str.rpartition would perform a left-partition when called with
5455 a unicode argument.
5456
Benjamin Peterson17f03ca2008-09-01 14:18:30 +00005457- Issue #3683: Fix compilation when --without-threads is given.

Vinay Sajip35e3b032008-09-01 14:33:59 +00005460 PyArg_ParseTuple and friends, which occurred when the argument for "s*"
Antoine Pitroud4ae97b2008-08-29 18:39:48 +00005461 was correctly parsed but parsing of subsequent arguments failed.
5462
Vinay Sajip35e3b032008-09-01 14:33:59 +00005463- Issue #2534: speed up isinstance() and issubclass() by 50-70%, so as to
Antoine Pitrou0668c622008-08-26 22:42:08 +00005464 match Python 2.5 speed despite the __instancecheck__ / __subclasscheck__
5465 mechanism. In the process, fix a bug where isinstance() and issubclass(),
5466 when given a tuple of classes as second argument, were looking up
5467 __instancecheck__ / __subclasscheck__ on the tuple rather than on each
5468 type object.
5469
Neal Norwitz18aa3882008-08-24 05:04:52 +00005470- Fix crashes on memory allocation failure found with failmalloc.

Brett Cannon1eaf0742008-09-02 01:25:16 +00005539 warnings.catch_warnings() along with some API cleanup. Expanding the tests
5540 for catch_warnings() also led to an improvement in the raising of a
5541 DeprecationWarning related to warnings.warn_explicit().
5542

5613-----------------
5614
Guido van Rossumf8402962008-08-20 15:01:50 +00005615- Issue #1878: Remove Py_TPFLAGS_HAVE_VERSION_TAG from
5616 Py_TPFLAGS_DEFAULT when not building the core. This means 3rd party
5617 extensions do not automatically benefit from the class attribute
5618 cache; they will have to explicitly add Py_TPFLAGS_HAVE_VERSION_TAG
5619 to their tp_flags field if they care. This is a backwards
5620 compatibility feature; in 3.0, all types will use the cache by
5621 default.
5622
Benjamin Petersonf647dc12008-08-20 01:27:30 +00005623- Keyword arguments can now follow starred arguments. (``f(a, *args,
5624 keyword=23)`` is now valid syntax.)
5625
Thomas Heller0ad5ae02008-08-19 19:25:04 +00005626- ctypes function pointers that are COM methods have a boolean True
5627 value again.
5628
Martin v. Löwisf91d46a2008-08-12 14:49:50 +00005629- Issue #3139: Make buffer-interface thread-safe wrt. PyArg_ParseTuple,
5630 by denying s# to parse objects that have a releasebuffer procedure,
5631 and introducing s*.
5632
Georg Brandl1e13ea92008-08-11 09:07:59 +00005633- Issue #3537: Fix an assertion failure when an empty but presized dict
5634 object was stored in the freelist.
5635
Mark Dickinsonb6467572008-08-04 21:30:09 +00005636- Issue #1481296: Make long(float('nan')) and int(float('nan')) raise
5637 ValueError consistently across platforms.
5638
Amaury Forgeot d'Arc39fd6722008-07-31 21:28:03 +00005639- Issue #3479: On platforms where sizeof(int) is smaller than sizeof(long)
5640 (64bit Unix, for example), unichr() would truncate its argument and return
5641 u'\x00' for unichr(2**32). Now it properly raises an OverflowError.
5642
Neal Norwitze7d8be82008-07-31 17:17:14 +00005643- Apply security patches from Apple.
5644
Amaury Forgeot d'Arc246daed2008-07-31 00:42:16 +00005645- Issue #2542: Now that issubclass() may call arbitrary code, ensure that
5646 PyErr_ExceptionMatches returns 0 when an exception occurs there.
5647
Antoine Pitrou92f82162008-07-25 22:22:08 +00005648- Issue #1819: function calls with several named parameters are now on
5649 average 35% faster (as measured by pybench).
5650
Amaury Forgeot d'Arce4921fe2008-07-21 22:00:38 +00005651- Issue #2378: An unexpected UnboundLocalError or NameError could appear when
5652 the python debugger steps into a class statement: the free variables (local
5653 variables defined in an outer scope) would be deleted from the outer scope.
5654
Gregory P. Smith0470bab2008-07-22 04:46:32 +00005655- Issue #2620: Overflow checking when allocating or reallocating memory
5656 was not always being done properly in some python types and extension
5657 modules. PyMem_MALLOC, PyMem_REALLOC, PyMem_NEW and PyMem_RESIZE have
5658 all been updated to perform better checks and places in the code that
5659 would previously leak memory on the error path when such an allocation
5660 failed have been fixed.

5664
Hirokazu Yamamoto838c79f2008-08-20 13:14:07 +00005665- Issue #3612: Added some missing basic types in ctypes.wintypes.
5666
Benjamin Petersone977ad42008-08-20 01:42:01 +00005667- The methods ``is_in_tuple()``, ``is_vararg()``, and ``is_keywordarg()`` of
5668 symtable.Symbol have been deprecated for removal in 3.0 and the next release.
5669
Amaury Forgeot d'Arc351ffb82008-08-18 19:23:47 +00005670- Issue #2234: distutils failed for some versions of the cygwin compiler. The
5671 version reported by these tools does not necessarily follow the python
5672 version numbering scheme, so the module is less strict when parsing it.
5673
Nick Coghlanf70385a2008-08-18 12:42:46 +00005674- Issue #2235: Added Py3k warnings for types which will become unhashable
5675 under the stricter __hash__ inheritance rules in 3.0. Several types
5676 which did not meet the rules for hash invariants and were already
5677 unhashable in 3.0 have now been explicitly flagged as unhashable in
5678 2.6 as well (collections.Mapping, collections.Set, unittest.TestSuite,
5679 xml.dom.minidom.NamedNodeMap, numbers.Number, UserList.UserList)
5680
Brett Cannon88f801d2008-08-18 00:46:22 +00005681- Update __all__ for cookielib, csv, os, urllib2, and weakref to include things

5794
Nick Coghlan2a0c2b12008-08-04 12:47:17 +00005795- Issue #643841: The language reference now provides more detailed

5807-----------------
5808
Georg Brandl3e483f62008-07-16 22:57:41 +00005809- Issue #3156: Fix inconsistent behavior of the bytearray type: all
5810 its methods now allow for items objects that can be converted to
5811 an integer using operator.index().
5812
Mark Dickinson64b7e502008-07-16 09:40:03 +00005813- Issue #3360: Fix incorrect parsing of '020000000000.0', which
5814 produced a ValueError instead of giving the correct float.
5815
Eric Smitha5fa5a22008-07-16 00:11:49 +00005816- Issue #3083: Add alternate (#) formatting for bin, oct, hex output
5817 for str.format(). This adds the prefix 0b, 0o, or 0x, respectively.
5818
Mark Dickinson7103aa42008-07-15 19:08:33 +00005819- Issue #3008: the float type has a new instance method 'float.hex'
5820 and a new class method 'float.fromhex' to convert floating-point
5821 numbers to and from hexadecimal strings, respectively.
5822
Nick Coghlan6d6bd442008-07-15 15:40:22 +00005823- Issue #2235: __hash__ is once again inherited by default. To allow
5824 collections.Hashable to remain meaningful in the presence of the
5825 default hash implementation (object.__hash__), it is now possible
5826 to explicit block inheritance of hash by setting __hash__=None at
5827 the Python level, or tp_hash=PyObject_HashNotImplemented at the C
5828 level.
5829
Nick Coghlanb028f502008-07-13 14:52:36 +00005830- Issue #3221: Issue a RuntimeWarning instead of raising SystemError if
5831 the parent module cannot be found while performing an absolute import.
5832 This means that an incorrectly defined __package__ attribute will
5833 now only prevent relative imports in that module rather than causing
5834 all imports from that module to fail.
5835
Nick Coghlan14ff9942008-07-08 14:21:42 +00005836- Issue #2517: Allow unicode messages in Exceptions again by correctly

5846 another thread's dictionary.
5847
Mark Dickinson1ec2fcd2008-06-20 14:53:43 +00005848- Issue #3004: Minor change to slice.indices(): the start and stop
5849 arguments are now treated identically, making the behaviour easier
5850 to describe and understand. For example, slice(None, -10,
5851 1).indices(9) now returns (0, 0, 1) instead of (0, -1, 1), and
5852 slice(None, 10, -1).indices(10) returns (9, 9, -1) instead of (9,
5853 10, -1).
5854
Georg Brandl278fc502008-07-19 12:46:12 +00005855- Issue #3219: Calling a function with repeated keyword arguments,
5856 f(a=2, a=23), would not cause a syntax error. This was a regression
5857 from 2.4 caused by the switch to the new compiler.

5896 both unnecessary (HTTP allows text content to be sent in several forms) and
Andrew M. Kuchlingcc3f2b12008-07-10 14:43:31 +00005897 wrong because the actual transmitted size could differ from the
Amaury Forgeot d'Arc0f7cddc2008-07-06 21:34:39 +00005898 content-length. The problem had been corrected in the 2.4 branch, but never

Ronald Oussoren5640ce22008-06-05 12:58:24 +00006305- On MacOS X it is now possible to install the framework in 64-bit
6306 mode or even as a 4-way universal binary (that is, PPC, i386,
Georg Brandl5cc774e2008-06-11 20:28:06 +00006307 PPC64 and x86_64 support in one binary).
Ronald Oussoren5640ce22008-06-05 12:58:24 +00006308
6309 This is controlled by the configure argument ``--with-universal-archs``:
6310
6311 - ``--with-universal-archs=all``: install 4-way universal
6312
6313 - ``--with-universal-archs=32-bit``: install 2-way universal, 32-bit (the default)
6314
6315 - ``--with-universal-archs=64-bit``: install 2-way universal, 64-bit
6316
6317 This option should be used in combination with ``--enable-universalsdk=``.
6318
6319 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 +00006369- Issue #1631171: Re-implement the 'warnings' module in C (the
6370 original Python code has been kept as backup). This will allow for
6371 using the 'warning's machinery in such places as the parser where
6372 use of pure Python code is not possible. Both the ``showarning()``
6373 and ``formatwarning()`` gain an optional 'line' argument which is
6374 not called by default for backwards-compatibility reasons. Setting
6375 ``warnings.showwarning()`` to an implementation that lacks support
6376 for the ``line`` argument will raise a DeprecationWarning.

Georg Brandl3ee81df2008-05-17 18:14:43 +00006439- Issue #2550: The approach used by client/server code for obtaining
6440 ports to listen on in network-oriented tests has been refined in an
6441 effort to facilitate running multiple instances of the entire
6442 regression test suite in parallel without issue.
6443 test_support.bind_port() has been fixed such that it will always
6444 return a unique port -- which wasn't always the case with the
6445 previous implementation, especially if socket options had been set
6446 that affected address reuse (i.e. SO_REUSEADDR, SO_REUSEPORT). The
6447 new implementation of bind_port() will actually raise an exception
6448 if it is passed an AF_INET/SOCK_STREAM socket with either the
6449 SO_REUSEADDR or SO_REUSEPORT socket option set. Furthermore, if
6450 available, bind_port() will set the SO_EXCLUSIVEADDRUSE option on
6451 the socket it's been passed. This currently only applies to
6452 Windows. This option prevents any other sockets from binding to the
6453 host/port we've bound to, thus removing the possibility of the
6454 'non-deterministic' behaviour, as Microsoft puts it, that occurs
6455 when a second SOCK_STREAM socket binds and accepts to a host/port
6456 that's already been bound by another socket. The optional preferred
6457 port parameter to bind_port() has been removed. Under no
6458 circumstances should tests be hard coding ports!
6459
6460 test_support.find_unused_port() has also been introduced, which will
6461 pass a temporary socket object to bind_port() in order to obtain an
6462 unused port. The temporary socket object is then closed and
6463 deleted, and the port is returned. This method should only be used
6464 for obtaining an unused port in order to pass to an external program
6465 (i.e. the -accept [port] argument to openssl's s_server mode) or as
6466 a parameter to a server-oriented class that doesn't give you direct
6467 access to the underlying socket used.
6468
6469 Finally, test_support.HOST has been introduced, which should be used
6470 for the host argument of any relevant socket calls (i.e. bind and
6471 connect).
Trent Nelsone41b0062008-04-08 23:47:30 +00006472
6473 The following tests were updated to following the new conventions:
Georg Brandl3ee81df2008-05-17 18:14:43 +00006474 test_socket, test_smtplib, test_asyncore, test_ssl, test_httplib,
Trent Nelsone41b0062008-04-08 23:47:30 +00006475 test_poplib, test_ftplib, test_telnetlib, test_socketserver,
6476 test_asynchat and test_socket_ssl.
6477
Georg Brandl3ee81df2008-05-17 18:14:43 +00006478 It is now possible for multiple instances of the regression test
6479 suite to run in parallel without issue.

Amaury Forgeot d'Arc9a0d3462008-03-23 09:55:29 +00006533- Issue #1477: With narrow Unicode builds, the unicode escape sequence
Georg Brandl3ee81df2008-05-17 18:14:43 +00006534 \Uxxxxxxxx did not accept values outside the Basic Multilingual
6535 Plane. This affected raw unicode literals and the
6536 'raw-unicode-escape' codec. Now UTF-16 surrogates are generated in
6537 this case, like normal unicode literals and the 'unicode-escape'
6538 codec.

Eric Smitha73fbe72008-02-23 03:09:44 +00006758- Added the future_builtins module, which contains hex() and oct().
6759 These are the PEP 3127 version of these functions, designed to be
6760 compatible with the hex() and oct() builtins from Python 3.0. They
6761 differ slightly in their output formats from the existing, unchanged
6762 Python 2.6 builtins. The expected usage of the future_builtins
6763 module is:
6764 from future_builtins import hex, oct
6765
Eric Smith7ef40bf2008-02-20 23:34:22 +00006766- Issue #1600: Modifed PyOS_ascii_formatd to use at most 2 digit
6767 exponents for exponents with absolute value < 100. Follows C99
6768 standard. This is a change on Windows, which would use 3 digits.
6769 Also, added 'n' to the formats that PyOS_ascii_formatd understands,
6770 so that any alterations it does to the resulting string will be
6771 available in stringlib/formatter.h (for float.__format__).
6772
Eric Smith5a3c1352008-02-19 13:21:56 +00006773- Implemented PEP 3101, Advanced String Formatting. This adds a new
6774 builtin format(); a format() method for str and unicode; a
6775 __format__() method to object, str, unicode, int, long, float, and
6776 datetime; the class string.Formatter; and the C API
6777 PyObject_Format().
6778
Georg Brandl3ee81df2008-05-17 18:14:43 +00006779- Fixed several potential crashes, all caused by specially crafted
6780 __del__ methods exploiting objects in temporarily inconsistent
6781 state.
Amaury Forgeot d'Arc632fad32008-02-16 20:55:24 +00006782

Georg Brandl3ee81df2008-05-17 18:14:43 +00006824- Patch #1473257: generator objects gain a gi_code attribute. This is
6825 the same object as the func_code attribute of the function that
6826 produced the generator.
Georg Brandl0cdf9a32008-01-26 14:14:20 +00006827
Georg Brandl3ee81df2008-05-17 18:14:43 +00006828- Issue #1920: "while 0" statements were completely removed by the
6829 compiler, even in the presence of an "else" clause, which is
6830 supposed to be run when the condition is false. Now the compiler
6831 correctly emits bytecode for the "else" suite.
Amaury Forgeot d'Arc31eaafe2008-01-24 22:59:25 +00006832
Guido van Rossumeead05f2008-01-24 18:21:02 +00006833- A few crashers fixed: weakref_in_del.py (issue #1377858);

6840
Georg Brandl3ee81df2008-05-17 18:14:43 +00006841- Issue #1915: Python compiles with --enable-unicode=no again. However
Christian Heimes082c9b02008-01-23 14:20:50 +00006842 several extension methods and modules do not work without unicode
6843 support.
6844

6849
Georg Brandl6caad7d2008-01-26 14:19:22 +00006850- Issue #1865: ``bytes`` as an alias for ``str`` and b"" as an alias "" were
Christian Heimes288e89a2008-01-18 18:24:07 +00006851 added.
6852
Christian Heimesc94e2b52008-01-14 04:13:37 +00006853- sys.float_info / PyFloat_GetInfo: The floating point information
6854 object was converted from a dict to a specialized structseq object.
6855
Georg Brandl3ee81df2008-05-17 18:14:43 +00006856- Patch #1816: Added sys.flags structseq. It exposes the status of
6857 most command line arguments and PYTHON* environment variables.
Christian Heimesf31b69f2008-01-14 03:42:48 +00006858
Georg Brandl3ee81df2008-05-17 18:14:43 +00006859- Objects/structseq.c: Implemented new structseq representation. The
6860 patch makes structseqs (e.g. the return value of os.stat) more
6861 readable.
Christian Heimes9c201962008-01-14 03:33:52 +00006862
Georg Brandl3ee81df2008-05-17 18:14:43 +00006863- Patch #1700288: added a type attribute cache that caches method
6864 accesses, resulting in speedups in heavily object-oriented code.
Amaury Forgeot d'Arce4c270c2008-01-14 00:29:41 +00006865
Neal Norwitz3fc15b82008-01-10 05:42:58 +00006866- Bug #1776: __import__() no longer accepts filenames on any platform.

6872 envvar and sys.dont_write_bytecode attribute. All these can be set
6873 to forbid Python to attempt to write compiled bytecode files.
Georg Brandl2da0fce2008-01-07 17:09:35 +00006874
Georg Brandl3ee81df2008-05-17 18:14:43 +00006875- Improve some exception messages when Windows fails to load an
6876 extension module. Now we get for example '%1 is not a valid Win32
6877 application' instead of 'error code 193'.

Christian Heimes0a8143f2007-12-18 23:22:54 +00006884- Issue #1635: Platform independent creation and representation of NaN
Georg Brandl3ee81df2008-05-17 18:14:43 +00006885 and INF. float("nan"), float("inf") and float("-inf") now work on
6886 every platform with IEEE 754 semantics.

Georg Brandl3ee81df2008-05-17 18:14:43 +00006936 smaller than LONG_MAX. Formerly, it raised an OverflowError. Now,
6937 automatically shifts from ints to longs.
Raymond Hettinger8f669372007-10-03 21:18:11 +00006938
Georg Brandl3ee81df2008-05-17 18:14:43 +00006939- Issue #1686386: Tuple's tp_repr did not take into account the
6940 possibility of having a self-referential tuple, which is possible
6941 from C code. Nor did object's tp_str consider that a type's tp_str
6942 could do something that could lead to an inifinite recursion.
6943 Py_ReprEnter() and Py_EnterRecursiveCall(), respectively, fixed the
6944 issues.
Brett Cannon0b14f242007-09-30 19:45:10 +00006945

6947 'print' statement to write to a file since the GIL was not released
6948 as needed. Now PyObject_Print() does the right thing along with
6949 various tp_print implementations of the built-in types and those in
6950 the collections module.
Brett Cannon01531592007-09-17 03:28:34 +00006951

Georg Brandl3ee81df2008-05-17 18:14:43 +00006960 PyObject_Call() never calling back out to Python code to trigger
6961 recursion depth updates/checks. Required the creation of a static
6962 RuntimeError instance in case normalizing an exception put the
6963 recursion check value past its limit. Fixes crashers

Guido van Rossum143b5642007-03-23 04:58:42 +00007012- Bug #1683368: The object.__init__() and object.__new__() methods are
7013 now stricter in rejecting excess arguments. The only time when
7014 either allows excess arguments is when it is not overridden and the
7015 other one is. For backwards compatibility, when both are
7016 overridden, it is a deprecation warning (for now; maybe a Py3k
Guido van Rossum234b1ff2007-03-23 19:39:01 +00007017 warning later). Also, type.__init__() insists on the same signature
7018 as supported by type.__new__().

Georg Brandl3ee81df2008-05-17 18:14:43 +00007020- Patch #1675423: PyComplex_AsCComplex() now tries to convert an
7021 object to complex using its __complex__() method before falling back
7022 to the __float__() method. Therefore, the functions in the cmath
7023 module now can operate on objects that define a __complex__()
7024 method.

Georg Brandl7b9c5552007-03-12 14:30:05 +00007042- Bug #1678647: write a newline after printing an exception in any
7043 case, even when converting the value to a string failed.
7044
Georg Brandl871f1bc2007-03-12 13:17:36 +00007045- The dir() function has been extended to call the __dir__() method on
Georg Brandl3ee81df2008-05-17 18:14:43 +00007046 its argument, if it exists. If not, it will work like before. This
7047 allows customizing the output of dir() in the presence of a
7048 __getattr__().

7058 raising a ValueError.
Collin Wintere38051d2007-03-09 20:33:07 +00007059
Georg Brandlaa2321b2007-03-07 00:40:28 +00007060- Patch #703779: unset __file__ in __main__ after running a file. This
Georg Brandl3ee81df2008-05-17 18:14:43 +00007061 makes the filenames the warning module prints much more sensible
7062 when a PYTHONSTARTUP file is used.

7076 sq_ass_slice instead of the sq_slice slot.
7077
Georg Brandl3ee81df2008-05-17 18:14:43 +00007078- When printing an unraisable error, don't print exceptions. before
7079 the name. This duplicates the behavior whening normally printing
7080 exceptions.

Georg Brandl2c1375c2006-10-12 11:27:59 +00007130- Bug #1545497: when given an explicit base, int() did ignore NULs
7131 embedded in the string to convert.
7132
Georg Brandl846f73a2006-10-08 07:11:54 +00007133- Bug #1569998: break inside a try statement (outside a loop) is now

Georg Brandl3ee81df2008-05-17 18:14:43 +00007181 generator expressions (x for x, in ... ) works again. Fixing this
7182 problem required changing the .pyc magic number. This means that
7183 .pyc files generated before 2.5c2 will be regenerated.

Georg Brandl3ee81df2008-05-17 18:14:43 +00007986- The implementation of UnicodeError objects has been simplified
7987 (start and end attributes are now stored directly as Py_ssize_t
7988 members).
Walter Dörwald84a3efe2007-06-13 16:57:12 +00007989
Georg Brandl3ee81df2008-05-17 18:14:43 +00007990- Issue #829951: In the smtplib module, SMTP.starttls() now complies
7991 with RFC 3207 and forgets any knowledge obtained from the server not
7992 obtained from the TLS negotiation itself. Patch contributed by Bill
7993 Fenner.
Gregory P. Smith2b3ba582008-01-17 08:03:17 +00007994
Georg Brandl3ee81df2008-05-17 18:14:43 +00007995- Issue #1339: The smtplib.SMTP class has been refactored a bit such
Gregory P. Smithbde4ae42008-01-17 08:35:49 +00007996 that the SMTP.starttls() caller no longer needs to call ehlo()
7997 beforehand. SMTP.starttls() now raises an exception of the server
Georg Brandl3ee81df2008-05-17 18:14:43 +00007998 does not claim to support starttls. Adds the
7999 SMTP.ehlo_or_helo_if_needed() method. Patch contributed by Bill
8000 Fenner.

8080 complex, tuple, list, dict, set, and frozenset. Formerly, it would
8081 silently miscode subclasses of those types. Now, it raises a
8082 ValueError instead.
Raymond Hettinger12e94202007-11-07 01:13:09 +00008083

Georg Brandl3ee81df2008-05-17 18:14:43 +00008098 time so that opening a database previously created with the DB_DUP
8099 or DB_DUPSORT flag set will keep the proper behavior on subsequent
8100 opens. Specifically: dictionary assignment to a DB object will
8101 replace all values for a given key when the database allows
8102 duplicate values. DB users should use DB.put(k, v) when they want
8103 to store duplicates; not DB[k] = v.
Gregory P. Smithec10a4a2007-11-05 02:32:26 +00008104

8110 characters with ASCII value less than 32. Also, it correctly quotes
8111 dots only if they occur on a single line, as opposed to the previous
8112 behavior of quoting dots if they are the second character of any
8113 line.
Georg Brandl4aef7272007-03-13 22:49:43 +00008114

8504 builds.

Georg Brandl3ee81df2008-05-17 18:14:43 +00008519- Removed the macfs module. It had been deprecated since Python 2.5.
8520 This lead to the deprecation of macostools.touched() as it relied
8521 solely on macfs and was a no-op under OS X.
