Florent Xiclunac2279652012-02-12 14:49:03 +0100666- Issue #13994: Earlier partial revert of Distutils enhancements in 2.7
Ned Deilyc47a4592012-02-11 20:40:24 +0100667 has left two versions of customize_compiler, the original in
668 distutils.sysconfig and another copy in distutils.ccompiler, with some

671 is the case in 3.x.
672
Ned Deily0d0ea482012-02-10 12:59:06 +0100673- Issue #13590: On OS X 10.7 and 10.6 with Xcode 4.2, building
674 Distutils-based packages with C extension modules may fail because
675 Apple has removed gcc-4.2, the version used to build python.org
676 64-bit/32-bit Pythons. If the user does not explicitly override
677 the default C compiler by setting the CC environment variable,
678 Distutils will now attempt to compile extension modules with clang
679 if gcc-4.2 is required but not found. Also as a convenience, if
680 the user does explicitly set CC, substitute its value as the default
681 compiler in the Distutils LDSHARED configuration variable for OS X.
682 (Note, the python.org 32-bit-only Pythons use gcc-4.0 and the 10.4u
683 SDK, neither of which are available in Xcode 4. This change does not
684 attempt to override settings to support their use with Xcode 4.)

Ned Deily87e82bb2011-06-28 19:52:59 -0700957- Issue #9516: On Mac OS X, change Distutils to no longer globally attempt to
958 check or set the MACOSX_DEPLOYMENT_TARGET environment variable for the
959 interpreter process. This could cause failures in non-Distutils subprocesses
960 and was unreliable since tests or user programs could modify the interpreter
961 environment after Distutils set it. Instead, have Distutils set the the
962 deployment target only in the environment of each build subprocess. It is
963 still possible to globally override the default by setting
964 MACOSX_DEPLOYMENT_TARGET before launching the interpreter; its value must be
965 greater or equal to the default value, the value with which the interpreter
966 was built.

995 updating the check interval, so if the user decreases the check interval,
996 the ticker doesn't have to wind down to zero from the old starting point
997 before the new interval takes effect. And if the user increases the
998 interval, it makes sure the new limit takes effect right away rather have an
999 early task switch before recognizing the new interval.

Mark Dickinsoncb61e5d2010-09-26 10:37:12 +00001795- Issue #9869: Make long() and PyNumber_Long return something of type
1796 long for a class whose __long__ method returns a plain int. This
1797 fixes an interpreter crash when initializing an instance of a long

1803 thread-local storage key.
1804
Victor Stinnercaafd772010-09-08 10:51:01 +00001805- Issue #4947: The write() method of sys.stdout and sys.stderr uses their
1806 encoding and errors attributes instead of using utf-8 in strict mode, to get
1807 the same behaviour than the print statement.
1808
Antoine Pitrou9cf85f12010-09-01 21:17:34 +00001809- Issue #9737: Fix a crash when trying to delete a slice or an item from

1949
Raymond Hettinger20397532010-09-12 02:11:45 +00001950- Issue #9825: removed __del__ from the definition of collections.OrderedDict.
1951 This prevents user-created self-referencing ordered dictionaries from
1952 becoming permanently uncollectable GC garbage. The downside is that
1953 removing __del__ means that the internal doubly-linked list has to wait for
1954 GC collection rather than freeing memory immediately when the refcnt drops
1955 to zero.
1956

1960
Antoine Pitrouc818ed42010-09-07 21:40:25 +00001961- Issue #9792: In case of connection failure, socket.create_connection()

1963 to fetch the original errno, or to filter timeout errors. Now the
1964 original error is re-raised.

Ezio Melottiab2eb0e2010-06-05 19:21:32 +00002414- Issue #8271: during the decoding of an invalid UTF-8 byte sequence, only the
2415 start byte and the continuation byte(s) are now considered invalid, instead
2416 of the number of bytes specified by the start byte.
2417 E.g.: '\xf1\x80AB'.decode('utf-8', 'replace') now returns u'\ufffdAB' and
2418 replaces with U+FFFD only the start byte ('\xf1') and the continuation byte

Georg Brandlfee0f442010-05-22 21:26:21 +00002626- Issue #8567: Fix precedence of signals in Decimal module: when a Decimal
2627 operation raises multiple signals and more than one of those signals is
2628 trapped, the specification determines the order in which the signals should be

2816 with a non-empty format string. This is an effort to future-proof user
2817 code. If a derived class does not currently implement __format__ but later
2818 adds its own __format__, it would most likely break user code that had
Antoine Pitrou01a196a2011-01-02 20:05:11 +00002819 supplied a format string. This will be changed to a DeprecationWarning in
Georg Brandlfee0f442010-05-22 21:26:21 +00002820 Python 3.3 and it will be an error in Python 3.4.

Antoine Pitrouf3fa0742010-01-31 22:26:04 +00003312- Issue #6939: Fix file I/O objects in the `io` module to keep the original
Georg Brandlba83f822010-03-14 09:50:54 +00003313 file position when calling `truncate()`. It would previously change the file
3314 position to the given argument, which goes against the tradition of
Antoine Pitrouf3fa0742010-01-31 22:26:04 +00003315 ftruncate() and other truncation APIs. Patch by Pascal Chambon.

Georg Brandlba83f822010-03-14 09:50:54 +00003317- Issue #7610: Reworked implementation of the internal ``zipfile.ZipExtFile``
3318 class used to represent files stored inside an archive. The new
3319 implementation is significantly faster and can be wrapped in a
3320 ``io.BufferedReader`` object for more speedups. It also solves an issue
3321 where interleaved calls to ``read()`` and ``readline()`` give wrong results.

Georg Brandlba83f822010-03-14 09:50:54 +00003412- The ``__complex__()`` method is now looked up on the class of instances to
3413 make it consistent with other special methods.

3417
Mark Dickinson1b34d252010-01-01 17:27:30 +00003418- Issue #5080: A number of functions and methods previously produced a
Georg Brandlba83f822010-03-14 09:50:54 +00003419 DeprecationWarning when passed a float argument where an integer was expected.
3420 These functions and methods now raise TypeError instead. The majority of the
3421 effects of this change are in the extension modules, but some core functions
3422 and methods are affected: notably the 'chr', 'range' and 'xrange' builtins,
3423 and many unicode/str methods.

3437 of integers: the result of a/b is now correctly rounded for ints a and b (at
3438 least on IEEE 754 platforms), and in particular does not depend on the
3439 internal representation of a long.

3447
Georg Brandlba83f822010-03-14 09:50:54 +00003448 These executables now work properly with the arch(1) command: ``arch -ppc

Georg Brandlba83f822010-03-14 09:50:54 +00003588- Issue #3382: 'F' formatting for float and complex now convert the result to
3589 upper case. This only affects 'inf' and 'nan', since 'f' no longer converts
3590 to 'g' for large values.
Amaury Forgeot d'Arcd7288712009-12-01 21:51:04 +00003591
Georg Brandlba83f822010-03-14 09:50:54 +00003592- Remove switch from "%f" formatting to "%g" formatting for floats larger than
3593 1e50 in absolute value.
Mark Dickinson9dd5e162009-11-23 20:54:09 +00003594
Georg Brandlba83f822010-03-14 09:50:54 +00003595- Remove restrictions on precision when formatting floats. E.g., "%.120g" %
3596 1e-100 used to raise OverflowError, but now gives the requested 120
3597 significant digits instead.

3604 10.6.
Ronald Oussoren315cd0c2009-11-19 16:25:21 +00003605
Georg Brandlba83f822010-03-14 09:50:54 +00003606- Issue #7117: ``repr(x)`` for a float x returns a result based on the shortest
3607 decimal string that's guaranteed to round back to x under correct rounding
3608 (with round-half-to-even rounding mode). Previously it gave a string based on
3609 rounding x to 17 decimal digits. repr(x) for a complex number behaves
3610 similarly. On platforms where the correctly-rounded strtod and dtoa code is
3611 not supported (see below), repr is unchanged.
Mark Dickinsonb678de82009-11-19 18:41:49 +00003612
Georg Brandlba83f822010-03-14 09:50:54 +00003613- Issue #7117: On almost all platforms: float-to-string and string-to-float
3614 conversions within Python are now correctly rounded. Places these conversions
3615 occur include: str for floats and complex numbers; the float and complex
3616 constructors; old-style and new-style numeric formatting; serialization and
3617 deserialization of floats and complex numbers using marshal, pickle and json;
3618 parsing of float and imaginary literals in Python code; Decimal-to-float
3619 conversion.
Mark Dickinsonb678de82009-11-19 18:41:49 +00003620
Georg Brandlba83f822010-03-14 09:50:54 +00003621 The conversions use a Python-adapted version of David Gay's well-known dtoa.c,
3622 providing correctly-rounded strtod and dtoa C functions. This code is
3623 supported on Windows, and on Unix-like platforms using gcc, icc or suncc as
3624 the C compiler. There may be a small number of platforms on which correct
3625 operation of this code cannot be guaranteed, so the code is not used: notably,
3626 this applies to platforms where the C double format is not IEEE 754 binary64,
3627 and to platforms on x86 hardware where the x87 FPU is set to 64-bit precision
3628 and Python's configure script is unable to determine how to change the FPU
3629 precision. On these platforms conversions use the platform strtod and dtoa,
3630 as before.
Mark Dickinsonb678de82009-11-19 18:41:49 +00003631
Georg Brandlba83f822010-03-14 09:50:54 +00003632- Issue #7117: Backport round implementation from Python 3.x. ``round()`` now
3633 uses the correctly-rounded string <-> float conversions described above (when
3634 available), and so produces correctly rounded results that will display nicely
3635 under the float repr. There are two related small changes: (1) round now
3636 accepts any class with an ``__index__()`` method for its second argument (but
3637 no longer accepts floats for the second argument), and (2) an excessively
3638 large second integer argument (e.g., ``round(1.234, 10**100)``) no longer
3639 raises an exception.

Mark Dickinsonb1d45852009-05-11 15:33:08 +00003781
Georg Brandlba83f822010-03-14 09:50:54 +00003782 (1) inf and nan strings with trailing whitespace were incorrectly rejected;
3783 (2) parsing of strings representing infinities and nans was locale aware; and
3784 (3) the interpretation of fromhex('-nan') didn't match that of float('-nan').

Georg Brandlba83f822010-03-14 09:50:54 +00003786- Issue #5920: For ``float.__format__()``, change the behavior with the empty
3787 presentation type (that is, not one of 'e', 'f', 'g', or 'n') to be like 'g'
3788 but with at least one decimal point and with a default precision
3789 of 12. Previously, the behavior the same but with a default precision of 6.
3790 This more closely matches ``str()``, and reduces surprises when adding
3791 alignment flags to the empty presentation type. This also affects the new
3792 complex.__format__ in the same way.
3793
3794- Issue #5890: In subclasses of 'property' the __doc__ attribute was shadowed by

4018 this code path is really executed because I cannot move to such directory on

5222 __long__ method could be packed by 'q', 'Q', '*q', '*Q'; for x with
5223 neither __int__ nor __long__, TypeError used to be raised (with a

Georg Brandlba83f822010-03-14 09:50:54 +00005278 leak-chasing test runs give sensible results. The previous method of reaping
5279 threads could return successfully while some Thread objects were still
5280 referenced. This also introduces a new private function: ``thread._count()``.

Georg Brandl2bd92a52009-10-11 21:10:07 +00005400- Issue #3850: recursion tests in Tools/scripts/find_recursion_limit.py can raise
Antoine Pitrou3c9f5412008-09-13 20:30:30 +00005401 AttributeError instead of RuntimeError, depending in which C API call
5402 exactly the recursion limit is exceeded. Consequently, both exception types
5403 are caught and silenced.

Martin v. Löwis9fa5a282008-09-11 06:53:30 +00005420- Issue #3642: Suppress warning in obmalloc when size_t is larger than uint.
5421
Amaury Forgeot d'Arc05e34492008-09-10 22:04:45 +00005422- Issue #3743: In a few places, PY_FORMAT_SIZE_T was incorrectly used with
5423 PyString_FromFormat or PyErr_Format to display size_t values. The macro
5424 PY_FORMAT_SIZE_T is designed to select the correct format for the OS
5425 ``printf`` function, whereas PyString_FromFormat has an independent
5426 implementation and uses "%zd" on all platforms for size_t values.
5427 This makes a difference on win64, where ``printf`` needs "%Id" to display
5428 64bit values.
5429
Benjamin Peterson97179b02008-09-09 20:55:01 +00005430- Issue #3634: _weakref.ref(Exception).__init__() gave invalid return value on
5431 error.
5432
Amaury Forgeot d'Arcd3ffb892008-09-09 07:24:30 +00005433- Issue #3777: long() applied to a float object now always return a long
5434 object; previously an int would be returned for small values. the __long__
5435 method is allowed to return either an int or a long, but the behaviour of
5436 float objects should not change to respect backward compatibility.
5437
Amaury Forgeot d'Arc3571fbf2008-09-01 19:52:00 +00005438- Issue #3751: str.rpartition would perform a left-partition when called with
5439 a unicode argument.
5440
Benjamin Peterson17f03ca2008-09-01 14:18:30 +00005441- Issue #3683: Fix compilation when --without-threads is given.
5442
Antoine Pitroud4ae97b2008-08-29 18:39:48 +00005443- Issue #3668: Fix a memory leak with the "s*" argument parser in
Vinay Sajip35e3b032008-09-01 14:33:59 +00005444 PyArg_ParseTuple and friends, which occurred when the argument for "s*"
Antoine Pitroud4ae97b2008-08-29 18:39:48 +00005445 was correctly parsed but parsing of subsequent arguments failed.
5446
Vinay Sajip35e3b032008-09-01 14:33:59 +00005447- Issue #2534: speed up isinstance() and issubclass() by 50-70%, so as to
Antoine Pitrou0668c622008-08-26 22:42:08 +00005448 match Python 2.5 speed despite the __instancecheck__ / __subclasscheck__
5449 mechanism. In the process, fix a bug where isinstance() and issubclass(),
5450 when given a tuple of classes as second argument, were looking up
5451 __instancecheck__ / __subclasscheck__ on the tuple rather than on each
5452 type object.
5453
Neal Norwitz18aa3882008-08-24 05:04:52 +00005454- Fix crashes on memory allocation failure found with failmalloc.
5455
5456- Fix memory leaks found with valgrind and update suppressions file.
5457
5458- Fix compiler warnings in opt mode which would lead to invalid memory reads.
5459
5460- Fix problem using wrong name in decimal module reported by pychecker.
5461
Christian Heimes7d4c3172008-08-22 19:47:25 +00005462- Silenced another compiler warning about a used but not defined
5463 function 'stringlib_contains_obj'.
5464
Benjamin Peterson712ee922008-08-24 18:10:20 +00005465- Added warnings on the use of ``__getslice__``, ``__setslice__``, or
5466 ``__delslice__``.
5467
Gregory P. Smith2bb25cc2008-09-02 05:29:51 +00005468- Issue #3678: Correctly pass LDFLAGS and LDLAST to the linker on shared
5469 library targets in the Makefile.
5470
Gregory P. Smith980b99b2008-09-07 05:15:18 +00005471- Issue #1204: The configure script now tests for additional libraries
5472 that may be required when linking against readline. This fixes issues
5473 with x86_64 builds on some platforms (a few Linux flavors and OpenBSD).

5484 stack usage in the case of deeply nested objects.
5485

Brett Cannon672237d2008-09-09 00:49:16 +00005497 return a list or None rather than a custom object.
5498
Benjamin Peterson6ac7d7c2008-09-06 19:28:11 +00005499- Issue #1638033: Cookie.Morsel gained the httponly attribute.

Brett Cannon1eaf0742008-09-02 01:25:16 +00005523 warnings.catch_warnings() along with some API cleanup. Expanding the tests
5524 for catch_warnings() also led to an improvement in the raising of a
5525 DeprecationWarning related to warnings.warn_explicit().
5526
Benjamin Peterson973e6c22008-09-01 23:12:58 +00005527- The deprecation warnings for the old camelCase threading API were removed.

5552 without limit.
5553
Benjamin Peterson37346b22008-08-23 20:27:43 +00005554- Issue #3643: Added a few more checks to _testcapi to prevent segfaults by

5596Core and Builtins
5597-----------------
5598
Guido van Rossumf8402962008-08-20 15:01:50 +00005599- Issue #1878: Remove Py_TPFLAGS_HAVE_VERSION_TAG from
5600 Py_TPFLAGS_DEFAULT when not building the core. This means 3rd party
5601 extensions do not automatically benefit from the class attribute
5602 cache; they will have to explicitly add Py_TPFLAGS_HAVE_VERSION_TAG
5603 to their tp_flags field if they care. This is a backwards
5604 compatibility feature; in 3.0, all types will use the cache by
5605 default.
5606
Benjamin Petersonf647dc12008-08-20 01:27:30 +00005607- Keyword arguments can now follow starred arguments. (``f(a, *args,
5608 keyword=23)`` is now valid syntax.)
5609
Thomas Heller0ad5ae02008-08-19 19:25:04 +00005610- ctypes function pointers that are COM methods have a boolean True
5611 value again.
5612
Martin v. Löwisf91d46a2008-08-12 14:49:50 +00005613- Issue #3139: Make buffer-interface thread-safe wrt. PyArg_ParseTuple,
5614 by denying s# to parse objects that have a releasebuffer procedure,
5615 and introducing s*.
5616
Georg Brandl1e13ea92008-08-11 09:07:59 +00005617- Issue #3537: Fix an assertion failure when an empty but presized dict
5618 object was stored in the freelist.
5619
Mark Dickinsonb6467572008-08-04 21:30:09 +00005620- Issue #1481296: Make long(float('nan')) and int(float('nan')) raise
5621 ValueError consistently across platforms.
5622
Amaury Forgeot d'Arc39fd6722008-07-31 21:28:03 +00005623- Issue #3479: On platforms where sizeof(int) is smaller than sizeof(long)
5624 (64bit Unix, for example), unichr() would truncate its argument and return
5625 u'\x00' for unichr(2**32). Now it properly raises an OverflowError.
5626
Neal Norwitze7d8be82008-07-31 17:17:14 +00005627- Apply security patches from Apple.
5628
Amaury Forgeot d'Arc246daed2008-07-31 00:42:16 +00005629- Issue #2542: Now that issubclass() may call arbitrary code, ensure that
5630 PyErr_ExceptionMatches returns 0 when an exception occurs there.
5631
Antoine Pitrou92f82162008-07-25 22:22:08 +00005632- Issue #1819: function calls with several named parameters are now on
5633 average 35% faster (as measured by pybench).
5634
Amaury Forgeot d'Arce4921fe2008-07-21 22:00:38 +00005635- Issue #2378: An unexpected UnboundLocalError or NameError could appear when
5636 the python debugger steps into a class statement: the free variables (local
5637 variables defined in an outer scope) would be deleted from the outer scope.
5638
Gregory P. Smith0470bab2008-07-22 04:46:32 +00005639- Issue #2620: Overflow checking when allocating or reallocating memory
5640 was not always being done properly in some python types and extension
5641 modules. PyMem_MALLOC, PyMem_REALLOC, PyMem_NEW and PyMem_RESIZE have
5642 all been updated to perform better checks and places in the code that
5643 would previously leak memory on the error path when such an allocation
5644 failed have been fixed.

Hirokazu Yamamoto838c79f2008-08-20 13:14:07 +00005649- Issue #3612: Added some missing basic types in ctypes.wintypes.
5650
Benjamin Petersone977ad42008-08-20 01:42:01 +00005651- The methods ``is_in_tuple()``, ``is_vararg()``, and ``is_keywordarg()`` of
5652 symtable.Symbol have been deprecated for removal in 3.0 and the next release.
5653
Amaury Forgeot d'Arc351ffb82008-08-18 19:23:47 +00005654- Issue #2234: distutils failed for some versions of the cygwin compiler. The
5655 version reported by these tools does not necessarily follow the python
5656 version numbering scheme, so the module is less strict when parsing it.
5657
Nick Coghlanf70385a2008-08-18 12:42:46 +00005658- Issue #2235: Added Py3k warnings for types which will become unhashable
5659 under the stricter __hash__ inheritance rules in 3.0. Several types
5660 which did not meet the rules for hash invariants and were already
5661 unhashable in 3.0 have now been explicitly flagged as unhashable in
5662 2.6 as well (collections.Mapping, collections.Set, unittest.TestSuite,
5663 xml.dom.minidom.NamedNodeMap, numbers.Number, UserList.UserList)
5664
Brett Cannon88f801d2008-08-18 00:46:22 +00005665- Update __all__ for cookielib, csv, os, urllib2, and weakref to include things
5666 imported into the module but exposed as part of the module's API.
5667
Brett Cannon7b96f072008-08-18 00:41:11 +00005668- Remove an unneeded import of abc.ABCMeta from 'inspect'.

Brett Cannon25c9d6a2008-08-17 22:10:11 +00005672- Remove unneeded imports of 'warnings' from shelve, filecmp, and dummy_thread.
5673
Hirokazu Yamamoto41a81eb2008-08-17 13:10:46 +00005674- Issue #3575: Incremental decoder's decode function now takes bytearray
5675 by using 's*' instead of 't#'.

5778
Nick Coghlan2a0c2b12008-08-04 12:47:17 +00005779- Issue #643841: The language reference now provides more detailed

5791-----------------
5792
Georg Brandl3e483f62008-07-16 22:57:41 +00005793- Issue #3156: Fix inconsistent behavior of the bytearray type: all
5794 its methods now allow for items objects that can be converted to
5795 an integer using operator.index().
5796
Mark Dickinson64b7e502008-07-16 09:40:03 +00005797- Issue #3360: Fix incorrect parsing of '020000000000.0', which
5798 produced a ValueError instead of giving the correct float.
5799
Eric Smitha5fa5a22008-07-16 00:11:49 +00005800- Issue #3083: Add alternate (#) formatting for bin, oct, hex output
5801 for str.format(). This adds the prefix 0b, 0o, or 0x, respectively.
5802
Mark Dickinson7103aa42008-07-15 19:08:33 +00005803- Issue #3008: the float type has a new instance method 'float.hex'
5804 and a new class method 'float.fromhex' to convert floating-point
5805 numbers to and from hexadecimal strings, respectively.
5806
Nick Coghlan6d6bd442008-07-15 15:40:22 +00005807- Issue #2235: __hash__ is once again inherited by default. To allow
5808 collections.Hashable to remain meaningful in the presence of the
5809 default hash implementation (object.__hash__), it is now possible
5810 to explicit block inheritance of hash by setting __hash__=None at
5811 the Python level, or tp_hash=PyObject_HashNotImplemented at the C
5812 level.
5813
Nick Coghlanb028f502008-07-13 14:52:36 +00005814- Issue #3221: Issue a RuntimeWarning instead of raising SystemError if
5815 the parent module cannot be found while performing an absolute import.
5816 This means that an incorrectly defined __package__ attribute will
5817 now only prevent relative imports in that module rather than causing
5818 all imports from that module to fail.
5819
Nick Coghlan14ff9942008-07-08 14:21:42 +00005820- Issue #2517: Allow unicode messages in Exceptions again by correctly

5830 another thread's dictionary.
5831
Mark Dickinson1ec2fcd2008-06-20 14:53:43 +00005832- Issue #3004: Minor change to slice.indices(): the start and stop
5833 arguments are now treated identically, making the behaviour easier
5834 to describe and understand. For example, slice(None, -10,
5835 1).indices(9) now returns (0, 0, 1) instead of (0, -1, 1), and
5836 slice(None, 10, -1).indices(10) returns (9, 9, -1) instead of (9,
5837 10, -1).
5838
Georg Brandl278fc502008-07-19 12:46:12 +00005839- Issue #3219: Calling a function with repeated keyword arguments,
5840 f(a=2, a=23), would not cause a syntax error. This was a regression
5841 from 2.4 caused by the switch to the new compiler.

5851 api functions without holding the GIL, which could lead to a fatal
5852 error when they failed.
5853
Martin v. Löwisaabf4042008-08-02 07:20:25 +00005854- Issue #799428: Fix Tkinter.Misc._nametowidget to unwrap Tcl command objects.

Amaury Forgeot d'Arc0f7cddc2008-07-06 21:34:39 +00005879- Issue #839496: SimpleHTTPServer used to open text files in text mode. This is
5880 both unnecessary (HTTP allows text content to be sent in several forms) and
Andrew M. Kuchlingcc3f2b12008-07-10 14:43:31 +00005881 wrong because the actual transmitted size could differ from the
Amaury Forgeot d'Arc0f7cddc2008-07-06 21:34:39 +00005882 content-length. The problem had been corrected in the 2.4 branch, but never

Nick Coghlanc060b0e2008-07-02 13:09:19 +00005898- Issue #3190: Pydoc now hides the automatic module attribute __package__ (the

6242 suitable sign) if n is large and negative; previously, it raised
6243 OverflowError.

Ronald Oussoren5640ce22008-06-05 12:58:24 +00006289- On MacOS X it is now possible to install the framework in 64-bit
6290 mode or even as a 4-way universal binary (that is, PPC, i386,
Georg Brandl5cc774e2008-06-11 20:28:06 +00006291 PPC64 and x86_64 support in one binary).
Ronald Oussoren5640ce22008-06-05 12:58:24 +00006292
6293 This is controlled by the configure argument ``--with-universal-archs``:
6294
6295 - ``--with-universal-archs=all``: install 4-way universal
6296
6297 - ``--with-universal-archs=32-bit``: install 2-way universal, 32-bit (the default)
6298
6299 - ``--with-universal-archs=64-bit``: install 2-way universal, 64-bit
6300
6301 This option should be used in combination with ``--enable-universalsdk=``.
6302
6303 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 +00006353- Issue #1631171: Re-implement the 'warnings' module in C (the
6354 original Python code has been kept as backup). This will allow for
6355 using the 'warning's machinery in such places as the parser where
6356 use of pure Python code is not possible. Both the ``showarning()``
6357 and ``formatwarning()`` gain an optional 'line' argument which is
6358 not called by default for backwards-compatibility reasons. Setting
6359 ``warnings.showwarning()`` to an implementation that lacks support
6360 for the ``line`` argument will raise a DeprecationWarning.

Georg Brandl3ee81df2008-05-17 18:14:43 +00006423- Issue #2550: The approach used by client/server code for obtaining
6424 ports to listen on in network-oriented tests has been refined in an
6425 effort to facilitate running multiple instances of the entire
6426 regression test suite in parallel without issue.
6427 test_support.bind_port() has been fixed such that it will always
6428 return a unique port -- which wasn't always the case with the
6429 previous implementation, especially if socket options had been set
6430 that affected address reuse (i.e. SO_REUSEADDR, SO_REUSEPORT). The
6431 new implementation of bind_port() will actually raise an exception
6432 if it is passed an AF_INET/SOCK_STREAM socket with either the
6433 SO_REUSEADDR or SO_REUSEPORT socket option set. Furthermore, if
6434 available, bind_port() will set the SO_EXCLUSIVEADDRUSE option on
6435 the socket it's been passed. This currently only applies to
6436 Windows. This option prevents any other sockets from binding to the
6437 host/port we've bound to, thus removing the possibility of the
6438 'non-deterministic' behaviour, as Microsoft puts it, that occurs
6439 when a second SOCK_STREAM socket binds and accepts to a host/port
6440 that's already been bound by another socket. The optional preferred
6441 port parameter to bind_port() has been removed. Under no
6442 circumstances should tests be hard coding ports!
6443
6444 test_support.find_unused_port() has also been introduced, which will
6445 pass a temporary socket object to bind_port() in order to obtain an
6446 unused port. The temporary socket object is then closed and
6447 deleted, and the port is returned. This method should only be used
6448 for obtaining an unused port in order to pass to an external program
6449 (i.e. the -accept [port] argument to openssl's s_server mode) or as
6450 a parameter to a server-oriented class that doesn't give you direct
6451 access to the underlying socket used.
6452
6453 Finally, test_support.HOST has been introduced, which should be used
6454 for the host argument of any relevant socket calls (i.e. bind and
6455 connect).
Trent Nelsone41b0062008-04-08 23:47:30 +00006456
6457 The following tests were updated to following the new conventions:
Georg Brandl3ee81df2008-05-17 18:14:43 +00006458 test_socket, test_smtplib, test_asyncore, test_ssl, test_httplib,
Trent Nelsone41b0062008-04-08 23:47:30 +00006459 test_poplib, test_ftplib, test_telnetlib, test_socketserver,
6460 test_asynchat and test_socket_ssl.
6461
Georg Brandl3ee81df2008-05-17 18:14:43 +00006462 It is now possible for multiple instances of the regression test
6463 suite to run in parallel without issue.

Amaury Forgeot d'Arc9a0d3462008-03-23 09:55:29 +00006517- Issue #1477: With narrow Unicode builds, the unicode escape sequence
Georg Brandl3ee81df2008-05-17 18:14:43 +00006518 \Uxxxxxxxx did not accept values outside the Basic Multilingual
6519 Plane. This affected raw unicode literals and the
6520 'raw-unicode-escape' codec. Now UTF-16 surrogates are generated in
6521 this case, like normal unicode literals and the 'unicode-escape'
6522 codec.

Eric Smitha73fbe72008-02-23 03:09:44 +00006742- Added the future_builtins module, which contains hex() and oct().
6743 These are the PEP 3127 version of these functions, designed to be
6744 compatible with the hex() and oct() builtins from Python 3.0. They
6745 differ slightly in their output formats from the existing, unchanged
6746 Python 2.6 builtins. The expected usage of the future_builtins
6747 module is:
6748 from future_builtins import hex, oct
6749
Eric Smith7ef40bf2008-02-20 23:34:22 +00006750- Issue #1600: Modifed PyOS_ascii_formatd to use at most 2 digit
6751 exponents for exponents with absolute value < 100. Follows C99
6752 standard. This is a change on Windows, which would use 3 digits.
6753 Also, added 'n' to the formats that PyOS_ascii_formatd understands,
6754 so that any alterations it does to the resulting string will be
6755 available in stringlib/formatter.h (for float.__format__).
6756
Eric Smith5a3c1352008-02-19 13:21:56 +00006757- Implemented PEP 3101, Advanced String Formatting. This adds a new
6758 builtin format(); a format() method for str and unicode; a
6759 __format__() method to object, str, unicode, int, long, float, and
6760 datetime; the class string.Formatter; and the C API
6761 PyObject_Format().
6762
Georg Brandl3ee81df2008-05-17 18:14:43 +00006763- Fixed several potential crashes, all caused by specially crafted
6764 __del__ methods exploiting objects in temporarily inconsistent
6765 state.
Amaury Forgeot d'Arc632fad32008-02-16 20:55:24 +00006766
Vinay Sajipb7edfc42008-04-02 21:10:23 +00006767- Issue #2115: Important speedup in setting __slot__ attributes. Also
Georg Brandl3ee81df2008-05-17 18:14:43 +00006768 prevent a possible crash: an Abstract Base Class would try to access
6769 a slot on a registered virtual subclass.
Amaury Forgeot d'Arc60d6c7f2008-02-15 21:22:45 +00006770

Georg Brandl3ee81df2008-05-17 18:14:43 +00006774- Clear all free lists during a gc.collect() of the highest generation
6775 in order to allow pymalloc to free more arenas. Python may give back
6776 memory to the OS earlier.
Christian Heimes3b718a72008-02-14 12:47:33 +00006777
Georg Brandl3ee81df2008-05-17 18:14:43 +00006778- Issue #2045: Fix an infinite recursion triggered when printing a
6779 subclass of collections.defaultdict, if its default_factory is set
6780 to a bound method.
Amaury Forgeot d'Arcb01aa432008-02-08 00:56:02 +00006781
Christian Heimesf75dbef2008-02-08 00:11:31 +00006782- Fixed a minor memory leak in dictobject.c. The content of the free
6783 list was not freed on interpreter shutdown.
6784
Georg Brandl21e99f42010-03-07 15:23:59 +00006785- Limit free list of method and built-in function objects to 256
Georg Brandl3ee81df2008-05-17 18:14:43 +00006786 entries each.
Christian Heimes6075a822008-02-06 12:44:34 +00006787
Georg Brandl3ee81df2008-05-17 18:14:43 +00006788- Patch #1953: Added ``sys._compact_freelists()`` and the C API
6789 functions ``PyInt_CompactFreeList`` and ``PyFloat_CompactFreeList``
Christian Heimes422051a2008-02-04 18:00:12 +00006790 to compact the internal free lists of pre-allocted ints and floats.
6791
Georg Brandl3ee81df2008-05-17 18:14:43 +00006792- Issue #1983: Fixed return type of fork(), fork1() and forkpty()
6793 calls. Python expected the return type int but the fork familie
6794 returns pi_t.

Georg Brandl3ee81df2008-05-17 18:14:43 +00006808- Patch #1473257: generator objects gain a gi_code attribute. This is
6809 the same object as the func_code attribute of the function that
6810 produced the generator.
Georg Brandl0cdf9a32008-01-26 14:14:20 +00006811
Georg Brandl3ee81df2008-05-17 18:14:43 +00006812- Issue #1920: "while 0" statements were completely removed by the
6813 compiler, even in the presence of an "else" clause, which is
6814 supposed to be run when the condition is false. Now the compiler
6815 correctly emits bytecode for the "else" suite.
Amaury Forgeot d'Arc31eaafe2008-01-24 22:59:25 +00006816
Guido van Rossumeead05f2008-01-24 18:21:02 +00006817- A few crashers fixed: weakref_in_del.py (issue #1377858);
6818 loosing_dict_ref.py (issue #1303614, test67.py);
6819 borrowed_ref_[34].py (not in tracker).
6820
Vinay Sajipd7cf32e2008-01-24 12:43:33 +00006821- Issue #1069410: The "can't load dll" message box on Windows is
Christian Heimesb2302ba2008-01-23 17:15:06 +00006822 suppressed while an extension is loaded by calling SetErrorMode in
6823 dynload_win.c. The error is still reported properly.
6824
Georg Brandl3ee81df2008-05-17 18:14:43 +00006825- Issue #1915: Python compiles with --enable-unicode=no again. However
Christian Heimes082c9b02008-01-23 14:20:50 +00006826 several extension methods and modules do not work without unicode
6827 support.
6828
Georg Brandl26543b12008-01-21 18:36:51 +00006829- Issue #1882: when compiling code from a string, encoding cookies in the

6833
Georg Brandl6caad7d2008-01-26 14:19:22 +00006834- Issue #1865: ``bytes`` as an alias for ``str`` and b"" as an alias "" were
Christian Heimes288e89a2008-01-18 18:24:07 +00006835 added.
6836
Christian Heimesc94e2b52008-01-14 04:13:37 +00006837- sys.float_info / PyFloat_GetInfo: The floating point information
6838 object was converted from a dict to a specialized structseq object.
6839
Georg Brandl3ee81df2008-05-17 18:14:43 +00006840- Patch #1816: Added sys.flags structseq. It exposes the status of
6841 most command line arguments and PYTHON* environment variables.
Christian Heimesf31b69f2008-01-14 03:42:48 +00006842
Georg Brandl3ee81df2008-05-17 18:14:43 +00006843- Objects/structseq.c: Implemented new structseq representation. The
6844 patch makes structseqs (e.g. the return value of os.stat) more
6845 readable.
Christian Heimes9c201962008-01-14 03:33:52 +00006846
Georg Brandl3ee81df2008-05-17 18:14:43 +00006847- Patch #1700288: added a type attribute cache that caches method
6848 accesses, resulting in speedups in heavily object-oriented code.
Amaury Forgeot d'Arce4c270c2008-01-14 00:29:41 +00006849
Neal Norwitz3fc15b82008-01-10 05:42:58 +00006850- Bug #1776: __import__() no longer accepts filenames on any platform.

6856 envvar and sys.dont_write_bytecode attribute. All these can be set
6857 to forbid Python to attempt to write compiled bytecode files.
Georg Brandl2da0fce2008-01-07 17:09:35 +00006858
Georg Brandl3ee81df2008-05-17 18:14:43 +00006859- Improve some exception messages when Windows fails to load an
6860 extension module. Now we get for example '%1 is not a valid Win32
6861 application' instead of 'error code 193'.
Amaury Forgeot d'Arce0b76952008-01-04 02:04:15 +00006862

Christian Heimes0a8143f2007-12-18 23:22:54 +00006868- Issue #1635: Platform independent creation and representation of NaN
Georg Brandl3ee81df2008-05-17 18:14:43 +00006869 and INF. float("nan"), float("inf") and float("-inf") now work on
6870 every platform with IEEE 754 semantics.
Christian Heimes0a8143f2007-12-18 23:22:54 +00006871
Georg Brandl3ee81df2008-05-17 18:14:43 +00006872- Compiler now generates simpler and faster code for dictionary
6873 literals. The oparg for BUILD_MAP now indicates an estimated
6874 dictionary size. There is a new opcode, STORE_MAP, for adding
6875 entries to the dictionary.

Georg Brandl3ee81df2008-05-17 18:14:43 +00006904- Patch #1739468: Directories and zipfiles containing a __main__.py
6905 file can now be directly executed by passing their name to the
6906 interpreter. The directory/zipfile is automatically inserted as the
6907 first entry in sys.path.
Nick Coghlan327a39b2007-11-18 11:56:28 +00006908
Georg Brandl3ee81df2008-05-17 18:14:43 +00006909- Issue #1265: Fix a problem with sys.settrace, if the tracing
6910 function uses a generator expression when at the same time the
6911 executed code is closing a paused generator.
Amaury Forgeot d'Arc0d75f092007-11-13 21:54:28 +00006912
Raymond Hettinger1760c8a2007-11-08 02:52:43 +00006913- sets and frozensets now have an isdisjoint() method.
6914
Raymond Hettinger3f8caa32007-10-24 01:28:33 +00006915- optimize the performance of builtin.sum().

6918
Georg Brandl21e99f42010-03-07 15:23:59 +00006919- The enumerate() built-in function is no longer bounded to sequences
Georg Brandl3ee81df2008-05-17 18:14:43 +00006920 smaller than LONG_MAX. Formerly, it raised an OverflowError. Now,
6921 automatically shifts from ints to longs.
Raymond Hettinger8f669372007-10-03 21:18:11 +00006922
Georg Brandl3ee81df2008-05-17 18:14:43 +00006923- Issue #1686386: Tuple's tp_repr did not take into account the
6924 possibility of having a self-referential tuple, which is possible
6925 from C code. Nor did object's tp_str consider that a type's tp_str
6926 could do something that could lead to an inifinite recursion.
6927 Py_ReprEnter() and Py_EnterRecursiveCall(), respectively, fixed the
6928 issues.
Brett Cannon0b14f242007-09-30 19:45:10 +00006929
Georg Brandl3ee81df2008-05-17 18:14:43 +00006930- Issue #1164: It was possible to trigger deadlock when using the
6931 'print' statement to write to a file since the GIL was not released
6932 as needed. Now PyObject_Print() does the right thing along with
6933 various tp_print implementations of the built-in types and those in
6934 the collections module.
Brett Cannon01531592007-09-17 03:28:34 +00006935
Georg Brandl3ee81df2008-05-17 18:14:43 +00006936- Issue #1147: Exceptions were directly allowing string exceptions in
6937 their throw() method even though string exceptions no longer
6938 allowed.
Brett Cannon4c20bc42007-09-11 21:02:28 +00006939
Georg Brandl3ee81df2008-05-17 18:14:43 +00006940- Issue #1096: Prevent a segfault from getting the repr of a very

Brett Cannona0c05512007-09-10 21:38:27 +00006942
Brett Cannon1e534b52007-09-07 04:18:30 +00006943- Issue #1202533: Fix infinite recursion calls triggered by calls to
Georg Brandl3ee81df2008-05-17 18:14:43 +00006944 PyObject_Call() never calling back out to Python code to trigger
6945 recursion depth updates/checks. Required the creation of a static
6946 RuntimeError instance in case normalizing an exception put the
6947 recursion check value past its limit. Fixes crashers
6948 infinite_rec_(1|2|4|5).py.
Brett Cannon1e534b52007-09-07 04:18:30 +00006949

Neal Norwitz0ac60192007-05-27 04:08:54 +00006963- Add new attribute names for function objects. All the func_* become
Georg Brandl3ee81df2008-05-17 18:14:43 +00006964 __*__ attributes. (Some already existed, e.g., __doc__ and
6965 __name__.)
Neal Norwitz0ac60192007-05-27 04:08:54 +00006966
Neal Norwitz8b2bfbc2007-05-23 06:35:32 +00006967- Add -3 option to the interpreter to warn about features that are

6969
Georg Brandl2134e752007-05-21 20:34:16 +00006970- Patch #1686487: you can now pass any mapping after '**' in function
6971 calls.
6972
Collin Winter62903052007-05-18 23:11:24 +00006973- except clauses may now be spelled either "except E, target:" or
Georg Brandl3ee81df2008-05-17 18:14:43 +00006974 "except E as target:". This is to provide forwards compatibility
6975 with Python 3.0.

Georg Brandl3ee81df2008-05-17 18:14:43 +00006979- Issue #1303614: don't expose object's __dict__ when the dict is
Georg Brandl21e99f42010-03-07 15:23:59 +00006980 inherited from a built-in base.
Armin Rigo9790a272007-05-02 19:23:31 +00006981
Vinay Sajip8549ce32007-05-06 17:53:37 +00006982- When __slots__ are set to a unicode string, make it work the same as
Neal Norwitzcbd9ee62007-04-14 05:25:50 +00006983 setting a plain string, ie don't expand to single letter identifiers.
6984
Raymond Hettinger13936692007-04-11 18:40:58 +00006985- Request #1191699: Slices can now be pickled.
6986
Raymond Hettinger4db5fe92007-04-12 04:10:00 +00006987- Request #1193128: str.translate() now allows a None argument for
6988 translations that only remove characters without re-mapping the
6989 remaining characters.
6990
Georg Brandl5cb76c12007-03-21 09:00:39 +00006991- Patch #1682205: a TypeError while unpacking an iterable is no longer

6995
Guido van Rossum143b5642007-03-23 04:58:42 +00006996- Bug #1683368: The object.__init__() and object.__new__() methods are
6997 now stricter in rejecting excess arguments. The only time when
6998 either allows excess arguments is when it is not overridden and the
6999 other one is. For backwards compatibility, when both are
7000 overridden, it is a deprecation warning (for now; maybe a Py3k
Guido van Rossum234b1ff2007-03-23 19:39:01 +00007001 warning later). Also, type.__init__() insists on the same signature
7002 as supported by type.__new__().

Georg Brandl3ee81df2008-05-17 18:14:43 +00007004- Patch #1675423: PyComplex_AsCComplex() now tries to convert an
7005 object to complex using its __complex__() method before falling back
7006 to the __float__() method. Therefore, the functions in the cmath
7007 module now can operate on objects that define a __complex__()
7008 method.

7028
Georg Brandl871f1bc2007-03-12 13:17:36 +00007029- The dir() function has been extended to call the __dir__() method on
Georg Brandl3ee81df2008-05-17 18:14:43 +00007030 its argument, if it exists. If not, it will work like before. This
7031 allows customizing the output of dir() in the presence of a
7032 __getattr__().

Georg Brandlaa2321b2007-03-07 00:40:28 +00007044- Patch #703779: unset __file__ in __main__ after running a file. This
Georg Brandl3ee81df2008-05-17 18:14:43 +00007045 makes the filenames the warning module prints much more sensible
7046 when a PYTHONSTARTUP file is used.

Georg Brandl2c1375c2006-10-12 11:27:59 +00007114- Bug #1545497: when given an explicit base, int() did ignore NULs
7115 embedded in the string to convert.
7116
Georg Brandl846f73a2006-10-08 07:11:54 +00007117- Bug #1569998: break inside a try statement (outside a loop) is now

Georg Brandl3ee81df2008-05-17 18:14:43 +00007165 generator expressions (x for x, in ... ) works again. Fixing this
7166 problem required changing the .pyc magic number. This means that
7167 .pyc files generated before 2.5c2 will be regenerated.

Georg Brandl3ee81df2008-05-17 18:14:43 +00007974- Issue #829951: In the smtplib module, SMTP.starttls() now complies
7975 with RFC 3207 and forgets any knowledge obtained from the server not
7976 obtained from the TLS negotiation itself. Patch contributed by Bill
7977 Fenner.
Gregory P. Smith2b3ba582008-01-17 08:03:17 +00007978
Georg Brandl3ee81df2008-05-17 18:14:43 +00007979- Issue #1339: The smtplib.SMTP class has been refactored a bit such
Gregory P. Smithbde4ae42008-01-17 08:35:49 +00007980 that the SMTP.starttls() caller no longer needs to call ehlo()
7981 beforehand. SMTP.starttls() now raises an exception of the server
Georg Brandl3ee81df2008-05-17 18:14:43 +00007982 does not claim to support starttls. Adds the
7983 SMTP.ehlo_or_helo_if_needed() method. Patch contributed by Bill
7984 Fenner.

8064 complex, tuple, list, dict, set, and frozenset. Formerly, it would
8065 silently miscode subclasses of those types. Now, it raises a
8066 ValueError instead.
Raymond Hettinger12e94202007-11-07 01:13:09 +00008067

Georg Brandl3ee81df2008-05-17 18:14:43 +00008082 time so that opening a database previously created with the DB_DUP
8083 or DB_DUPSORT flag set will keep the proper behavior on subsequent
8084 opens. Specifically: dictionary assignment to a DB object will
8085 replace all values for a given key when the database allows
8086 duplicate values. DB users should use DB.put(k, v) when they want
8087 to store duplicates; not DB[k] = v.
Gregory P. Smithec10a4a2007-11-05 02:32:26 +00008088

8094 characters with ASCII value less than 32. Also, it correctly quotes
8095 dots only if they occur on a single line, as opposed to the previous
8096 behavior of quoting dots if they are the second character of any
8097 line.
Georg Brandl4aef7272007-03-13 22:49:43 +00008098
