673 distutils.sysconfig and another copy in distutils.ccompiler, with some

Ned Deily0d0ea482012-02-10 12:59:06 +0100678- Issue #13590: On OS X 10.7 and 10.6 with Xcode 4.2, building
679 Distutils-based packages with C extension modules may fail because
680 Apple has removed gcc-4.2, the version used to build python.org
681 64-bit/32-bit Pythons. If the user does not explicitly override
682 the default C compiler by setting the CC environment variable,
683 Distutils will now attempt to compile extension modules with clang
684 if gcc-4.2 is required but not found. Also as a convenience, if
685 the user does explicitly set CC, substitute its value as the default
686 compiler in the Distutils LDSHARED configuration variable for OS X.
687 (Note, the python.org 32-bit-only Pythons use gcc-4.0 and the 10.4u
688 SDK, neither of which are available in Xcode 4. This change does not
689 attempt to override settings to support their use with Xcode 4.)

Ned Deily87e82bb2011-06-28 19:52:59 -0700962- Issue #9516: On Mac OS X, change Distutils to no longer globally attempt to
963 check or set the MACOSX_DEPLOYMENT_TARGET environment variable for the
964 interpreter process. This could cause failures in non-Distutils subprocesses
965 and was unreliable since tests or user programs could modify the interpreter
966 environment after Distutils set it. Instead, have Distutils set the the
967 deployment target only in the environment of each build subprocess. It is
968 still possible to globally override the default by setting
969 MACOSX_DEPLOYMENT_TARGET before launching the interpreter; its value must be
970 greater or equal to the default value, the value with which the interpreter
971 was built.

1000 updating the check interval, so if the user decreases the check interval,
1001 the ticker doesn't have to wind down to zero from the old starting point
1002 before the new interval takes effect. And if the user increases the
1003 interval, it makes sure the new limit takes effect right away rather have an
1004 early task switch before recognizing the new interval.

1954
Raymond Hettinger20397532010-09-12 02:11:45 +00001955- Issue #9825: removed __del__ from the definition of collections.OrderedDict.
1956 This prevents user-created self-referencing ordered dictionaries from
1957 becoming permanently uncollectable GC garbage. The downside is that
1958 removing __del__ means that the internal doubly-linked list has to wait for
1959 GC collection rather than freeing memory immediately when the refcnt drops
1960 to zero.

1965
Antoine Pitrouc818ed42010-09-07 21:40:25 +00001966- Issue #9792: In case of connection failure, socket.create_connection()
1967 would swallow the exception and raise a new one, making it impossible
1968 to fetch the original errno, or to filter timeout errors. Now the
1969 original error is re-raised.

Ezio Melottiab2eb0e2010-06-05 19:21:32 +00002419- Issue #8271: during the decoding of an invalid UTF-8 byte sequence, only the
2420 start byte and the continuation byte(s) are now considered invalid, instead
2421 of the number of bytes specified by the start byte.
2422 E.g.: '\xf1\x80AB'.decode('utf-8', 'replace') now returns u'\ufffdAB' and
2423 replaces with U+FFFD only the start byte ('\xf1') and the continuation byte
2424 ('\x80') even if '\xf1' is the start byte of a 4-bytes sequence.

2821 with a non-empty format string. This is an effort to future-proof user
2822 code. If a derived class does not currently implement __format__ but later
2823 adds its own __format__, it would most likely break user code that had
Antoine Pitrou01a196a2011-01-02 20:05:11 +00002824 supplied a format string. This will be changed to a DeprecationWarning in
Georg Brandlfee0f442010-05-22 21:26:21 +00002825 Python 3.3 and it will be an error in Python 3.4.

2899 makes Fraction <=> complex comparisons consistent with int <=> complex, float
2900 <=> complex, and complex <=> complex comparisons.

Antoine Pitrouf3fa0742010-01-31 22:26:04 +00003317- Issue #6939: Fix file I/O objects in the `io` module to keep the original
Georg Brandlba83f822010-03-14 09:50:54 +00003318 file position when calling `truncate()`. It would previously change the file
3319 position to the given argument, which goes against the tradition of
Antoine Pitrouf3fa0742010-01-31 22:26:04 +00003320 ftruncate() and other truncation APIs. Patch by Pascal Chambon.

Georg Brandlba83f822010-03-14 09:50:54 +00003322- Issue #7610: Reworked implementation of the internal ``zipfile.ZipExtFile``
3323 class used to represent files stored inside an archive. The new
3324 implementation is significantly faster and can be wrapped in a
3325 ``io.BufferedReader`` object for more speedups. It also solves an issue
3326 where interleaved calls to ``read()`` and ``readline()`` give wrong results.

3339 encoded string for them. This ensures that the upload and register commands
3340 send the correct values to PyPI without any error.

3415-----------------
3416
Georg Brandlba83f822010-03-14 09:50:54 +00003417- The ``__complex__()`` method is now looked up on the class of instances to
3418 make it consistent with other special methods.

Antoine Pitrou5b7139a2010-01-02 21:12:58 +00003420- Issue #7462: Implement the stringlib fast search algorithm for the `rfind`,
3421 `rindex`, `rsplit` and `rpartition` methods. Patch by Florent Xicluna.
3422
Mark Dickinson1b34d252010-01-01 17:27:30 +00003423- Issue #5080: A number of functions and methods previously produced a
Georg Brandlba83f822010-03-14 09:50:54 +00003424 DeprecationWarning when passed a float argument where an integer was expected.
3425 These functions and methods now raise TypeError instead. The majority of the
3426 effects of this change are in the extension modules, but some core functions
3427 and methods are affected: notably the 'chr', 'range' and 'xrange' builtins,
3428 and many unicode/str methods.

3442 of integers: the result of a/b is now correctly rounded for ints a and b (at
3443 least on IEEE 754 platforms), and in particular does not depend on the
3444 internal representation of a long.

3452
Georg Brandlba83f822010-03-14 09:50:54 +00003453 These executables now work properly with the arch(1) command: ``arch -ppc
3454 python`` will start a universal binary version of python in PPC mode (unlike

Georg Brandlba83f822010-03-14 09:50:54 +00003611- Issue #7117: ``repr(x)`` for a float x returns a result based on the shortest
3612 decimal string that's guaranteed to round back to x under correct rounding
3613 (with round-half-to-even rounding mode). Previously it gave a string based on
3614 rounding x to 17 decimal digits. repr(x) for a complex number behaves
3615 similarly. On platforms where the correctly-rounded strtod and dtoa code is
3616 not supported (see below), repr is unchanged.
Mark Dickinsonb678de82009-11-19 18:41:49 +00003617
Georg Brandlba83f822010-03-14 09:50:54 +00003618- Issue #7117: On almost all platforms: float-to-string and string-to-float
3619 conversions within Python are now correctly rounded. Places these conversions
3620 occur include: str for floats and complex numbers; the float and complex
3621 constructors; old-style and new-style numeric formatting; serialization and
3622 deserialization of floats and complex numbers using marshal, pickle and json;
3623 parsing of float and imaginary literals in Python code; Decimal-to-float
3624 conversion.
Mark Dickinsonb678de82009-11-19 18:41:49 +00003625
Georg Brandlba83f822010-03-14 09:50:54 +00003626 The conversions use a Python-adapted version of David Gay's well-known dtoa.c,
3627 providing correctly-rounded strtod and dtoa C functions. This code is
3628 supported on Windows, and on Unix-like platforms using gcc, icc or suncc as
3629 the C compiler. There may be a small number of platforms on which correct
3630 operation of this code cannot be guaranteed, so the code is not used: notably,
3631 this applies to platforms where the C double format is not IEEE 754 binary64,
3632 and to platforms on x86 hardware where the x87 FPU is set to 64-bit precision
3633 and Python's configure script is unable to determine how to change the FPU
3634 precision. On these platforms conversions use the platform strtod and dtoa,
3635 as before.
Mark Dickinsonb678de82009-11-19 18:41:49 +00003636
Georg Brandlba83f822010-03-14 09:50:54 +00003637- Issue #7117: Backport round implementation from Python 3.x. ``round()`` now
3638 uses the correctly-rounded string <-> float conversions described above (when
3639 available), and so produces correctly rounded results that will display nicely
3640 under the float repr. There are two related small changes: (1) round now
3641 accepts any class with an ``__index__()`` method for its second argument (but
3642 no longer accepts floats for the second argument), and (2) an excessively
3643 large second integer argument (e.g., ``round(1.234, 10**100)``) no longer
3644 raises an exception.

Mark Dickinsonb1d45852009-05-11 15:33:08 +00003786
Georg Brandlba83f822010-03-14 09:50:54 +00003787 (1) inf and nan strings with trailing whitespace were incorrectly rejected;
3788 (2) parsing of strings representing infinities and nans was locale aware; and
3789 (3) the interpretation of fromhex('-nan') didn't match that of float('-nan').

Georg Brandlba83f822010-03-14 09:50:54 +00003791- Issue #5920: For ``float.__format__()``, change the behavior with the empty
3792 presentation type (that is, not one of 'e', 'f', 'g', or 'n') to be like 'g'
3793 but with at least one decimal point and with a default precision
3794 of 12. Previously, the behavior the same but with a default precision of 6.
3795 This more closely matches ``str()``, and reduces surprises when adding
3796 alignment flags to the empty presentation type. This also affects the new
3797 complex.__format__ in the same way.
3798
3799- Issue #5890: In subclasses of 'property' the __doc__ attribute was shadowed by

5227 __long__ method could be packed by 'q', 'Q', '*q', '*Q'; for x with
5228 neither __int__ nor __long__, TypeError used to be raised (with a

Georg Brandlba83f822010-03-14 09:50:54 +00005283 leak-chasing test runs give sensible results. The previous method of reaping
5284 threads could return successfully while some Thread objects were still
5285 referenced. This also introduces a new private function: ``thread._count()``.
Antoine Pitrou59c44f32009-10-30 17:07:08 +00005286
Georg Brandlba83f822010-03-14 09:50:54 +00005287- Issue #7151: Fixed regrtest -j so that output to stderr from a test no longer

Georg Brandlba83f822010-03-14 09:50:54 +00005304 the same behaviour as test_ttkguionly (and now also test_tk) which is to skip

Georg Brandl2bd92a52009-10-11 21:10:07 +00005405- Issue #3850: recursion tests in Tools/scripts/find_recursion_limit.py can raise
Antoine Pitrou3c9f5412008-09-13 20:30:30 +00005406 AttributeError instead of RuntimeError, depending in which C API call
5407 exactly the recursion limit is exceeded. Consequently, both exception types
5408 are caught and silenced.

5424
Martin v. Löwis9fa5a282008-09-11 06:53:30 +00005425- Issue #3642: Suppress warning in obmalloc when size_t is larger than uint.
5426
Amaury Forgeot d'Arc05e34492008-09-10 22:04:45 +00005427- Issue #3743: In a few places, PY_FORMAT_SIZE_T was incorrectly used with
5428 PyString_FromFormat or PyErr_Format to display size_t values. The macro
5429 PY_FORMAT_SIZE_T is designed to select the correct format for the OS
5430 ``printf`` function, whereas PyString_FromFormat has an independent
5431 implementation and uses "%zd" on all platforms for size_t values.
5432 This makes a difference on win64, where ``printf`` needs "%Id" to display
5433 64bit values.
5434
Benjamin Peterson97179b02008-09-09 20:55:01 +00005435- Issue #3634: _weakref.ref(Exception).__init__() gave invalid return value on
5436 error.
5437
Amaury Forgeot d'Arcd3ffb892008-09-09 07:24:30 +00005438- Issue #3777: long() applied to a float object now always return a long
5439 object; previously an int would be returned for small values. the __long__
5440 method is allowed to return either an int or a long, but the behaviour of
5441 float objects should not change to respect backward compatibility.
5442
Amaury Forgeot d'Arc3571fbf2008-09-01 19:52:00 +00005443- Issue #3751: str.rpartition would perform a left-partition when called with
5444 a unicode argument.
5445
Benjamin Peterson17f03ca2008-09-01 14:18:30 +00005446- Issue #3683: Fix compilation when --without-threads is given.
5447
Antoine Pitroud4ae97b2008-08-29 18:39:48 +00005448- Issue #3668: Fix a memory leak with the "s*" argument parser in
Vinay Sajip35e3b032008-09-01 14:33:59 +00005449 PyArg_ParseTuple and friends, which occurred when the argument for "s*"
Antoine Pitroud4ae97b2008-08-29 18:39:48 +00005450 was correctly parsed but parsing of subsequent arguments failed.
5451
Vinay Sajip35e3b032008-09-01 14:33:59 +00005452- Issue #2534: speed up isinstance() and issubclass() by 50-70%, so as to
Antoine Pitrou0668c622008-08-26 22:42:08 +00005453 match Python 2.5 speed despite the __instancecheck__ / __subclasscheck__
5454 mechanism. In the process, fix a bug where isinstance() and issubclass(),
5455 when given a tuple of classes as second argument, were looking up
5456 __instancecheck__ / __subclasscheck__ on the tuple rather than on each
5457 type object.
5458
Neal Norwitz18aa3882008-08-24 05:04:52 +00005459- Fix crashes on memory allocation failure found with failmalloc.
5460
5461- Fix memory leaks found with valgrind and update suppressions file.
5462
5463- Fix compiler warnings in opt mode which would lead to invalid memory reads.
5464
5465- Fix problem using wrong name in decimal module reported by pychecker.
5466
Christian Heimes7d4c3172008-08-22 19:47:25 +00005467- Silenced another compiler warning about a used but not defined
5468 function 'stringlib_contains_obj'.
5469
Benjamin Peterson712ee922008-08-24 18:10:20 +00005470- Added warnings on the use of ``__getslice__``, ``__setslice__``, or
5471 ``__delslice__``.
5472
Gregory P. Smith2bb25cc2008-09-02 05:29:51 +00005473- Issue #3678: Correctly pass LDFLAGS and LDLAST to the linker on shared
5474 library targets in the Makefile.
5475
Gregory P. Smith980b99b2008-09-07 05:15:18 +00005476- Issue #1204: The configure script now tests for additional libraries
5477 that may be required when linking against readline. This fixes issues
5478 with x86_64 builds on some platforms (a few Linux flavors and OpenBSD).

Brett Cannon672237d2008-09-09 00:49:16 +00005502 return a list or None rather than a custom object.
5503
Benjamin Peterson6ac7d7c2008-09-06 19:28:11 +00005504- Issue #1638033: Cookie.Morsel gained the httponly attribute.

Brett Cannon1eaf0742008-09-02 01:25:16 +00005528 warnings.catch_warnings() along with some API cleanup. Expanding the tests
5529 for catch_warnings() also led to an improvement in the raising of a
5530 DeprecationWarning related to warnings.warn_explicit().
5531
Benjamin Peterson973e6c22008-09-01 23:12:58 +00005532- The deprecation warnings for the old camelCase threading API were removed.

Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00005600
5601Core and Builtins
5602-----------------
5603
Guido van Rossumf8402962008-08-20 15:01:50 +00005604- Issue #1878: Remove Py_TPFLAGS_HAVE_VERSION_TAG from
5605 Py_TPFLAGS_DEFAULT when not building the core. This means 3rd party
5606 extensions do not automatically benefit from the class attribute
5607 cache; they will have to explicitly add Py_TPFLAGS_HAVE_VERSION_TAG
5608 to their tp_flags field if they care. This is a backwards
5609 compatibility feature; in 3.0, all types will use the cache by
5610 default.
5611
Benjamin Petersonf647dc12008-08-20 01:27:30 +00005612- Keyword arguments can now follow starred arguments. (``f(a, *args,
5613 keyword=23)`` is now valid syntax.)
5614
Thomas Heller0ad5ae02008-08-19 19:25:04 +00005615- ctypes function pointers that are COM methods have a boolean True
5616 value again.
5617
Martin v. Löwisf91d46a2008-08-12 14:49:50 +00005618- Issue #3139: Make buffer-interface thread-safe wrt. PyArg_ParseTuple,
5619 by denying s# to parse objects that have a releasebuffer procedure,
5620 and introducing s*.
5621
Georg Brandl1e13ea92008-08-11 09:07:59 +00005622- Issue #3537: Fix an assertion failure when an empty but presized dict
5623 object was stored in the freelist.
5624
Mark Dickinsonb6467572008-08-04 21:30:09 +00005625- Issue #1481296: Make long(float('nan')) and int(float('nan')) raise
5626 ValueError consistently across platforms.
5627
Amaury Forgeot d'Arc39fd6722008-07-31 21:28:03 +00005628- Issue #3479: On platforms where sizeof(int) is smaller than sizeof(long)
5629 (64bit Unix, for example), unichr() would truncate its argument and return
5630 u'\x00' for unichr(2**32). Now it properly raises an OverflowError.
5631
Neal Norwitze7d8be82008-07-31 17:17:14 +00005632- Apply security patches from Apple.
5633
Amaury Forgeot d'Arc246daed2008-07-31 00:42:16 +00005634- Issue #2542: Now that issubclass() may call arbitrary code, ensure that
5635 PyErr_ExceptionMatches returns 0 when an exception occurs there.
5636
Antoine Pitrou92f82162008-07-25 22:22:08 +00005637- Issue #1819: function calls with several named parameters are now on
5638 average 35% faster (as measured by pybench).
5639
Amaury Forgeot d'Arce4921fe2008-07-21 22:00:38 +00005640- Issue #2378: An unexpected UnboundLocalError or NameError could appear when
5641 the python debugger steps into a class statement: the free variables (local
5642 variables defined in an outer scope) would be deleted from the outer scope.
5643
Gregory P. Smith0470bab2008-07-22 04:46:32 +00005644- Issue #2620: Overflow checking when allocating or reallocating memory
5645 was not always being done properly in some python types and extension
5646 modules. PyMem_MALLOC, PyMem_REALLOC, PyMem_NEW and PyMem_RESIZE have
5647 all been updated to perform better checks and places in the code that
5648 would previously leak memory on the error path when such an allocation
5649 failed have been fixed.

5653
Hirokazu Yamamoto838c79f2008-08-20 13:14:07 +00005654- Issue #3612: Added some missing basic types in ctypes.wintypes.
5655
Benjamin Petersone977ad42008-08-20 01:42:01 +00005656- The methods ``is_in_tuple()``, ``is_vararg()``, and ``is_keywordarg()`` of
5657 symtable.Symbol have been deprecated for removal in 3.0 and the next release.
5658
Amaury Forgeot d'Arc351ffb82008-08-18 19:23:47 +00005659- Issue #2234: distutils failed for some versions of the cygwin compiler. The
5660 version reported by these tools does not necessarily follow the python
5661 version numbering scheme, so the module is less strict when parsing it.
5662
Nick Coghlanf70385a2008-08-18 12:42:46 +00005663- Issue #2235: Added Py3k warnings for types which will become unhashable
5664 under the stricter __hash__ inheritance rules in 3.0. Several types
5665 which did not meet the rules for hash invariants and were already
5666 unhashable in 3.0 have now been explicitly flagged as unhashable in
5667 2.6 as well (collections.Mapping, collections.Set, unittest.TestSuite,
5668 xml.dom.minidom.NamedNodeMap, numbers.Number, UserList.UserList)
5669
Brett Cannon88f801d2008-08-18 00:46:22 +00005670- Update __all__ for cookielib, csv, os, urllib2, and weakref to include things
5671 imported into the module but exposed as part of the module's API.
5672
Brett Cannon7b96f072008-08-18 00:41:11 +00005673- Remove an unneeded import of abc.ABCMeta from 'inspect'.
5674
Brett Cannon46225e72008-08-18 00:36:52 +00005675- Remove unneeded imports of 'sys' and 'warnings' from 'io'.

Brett Cannon25c9d6a2008-08-17 22:10:11 +00005677- Remove unneeded imports of 'warnings' from shelve, filecmp, and dummy_thread.
5678
Hirokazu Yamamoto41a81eb2008-08-17 13:10:46 +00005679- Issue #3575: Incremental decoder's decode function now takes bytearray
5680 by using 's*' instead of 't#'.

5783
Nick Coghlan2a0c2b12008-08-04 12:47:17 +00005784- Issue #643841: The language reference now provides more detailed

5796-----------------
5797
Georg Brandl3e483f62008-07-16 22:57:41 +00005798- Issue #3156: Fix inconsistent behavior of the bytearray type: all
5799 its methods now allow for items objects that can be converted to
5800 an integer using operator.index().
5801
Mark Dickinson64b7e502008-07-16 09:40:03 +00005802- Issue #3360: Fix incorrect parsing of '020000000000.0', which
5803 produced a ValueError instead of giving the correct float.
5804
Eric Smitha5fa5a22008-07-16 00:11:49 +00005805- Issue #3083: Add alternate (#) formatting for bin, oct, hex output
5806 for str.format(). This adds the prefix 0b, 0o, or 0x, respectively.
5807
Mark Dickinson7103aa42008-07-15 19:08:33 +00005808- Issue #3008: the float type has a new instance method 'float.hex'
5809 and a new class method 'float.fromhex' to convert floating-point
5810 numbers to and from hexadecimal strings, respectively.
5811
Nick Coghlan6d6bd442008-07-15 15:40:22 +00005812- Issue #2235: __hash__ is once again inherited by default. To allow
5813 collections.Hashable to remain meaningful in the presence of the
5814 default hash implementation (object.__hash__), it is now possible
5815 to explicit block inheritance of hash by setting __hash__=None at
5816 the Python level, or tp_hash=PyObject_HashNotImplemented at the C
5817 level.
5818
Nick Coghlanb028f502008-07-13 14:52:36 +00005819- Issue #3221: Issue a RuntimeWarning instead of raising SystemError if
5820 the parent module cannot be found while performing an absolute import.
5821 This means that an incorrectly defined __package__ attribute will
5822 now only prevent relative imports in that module rather than causing
5823 all imports from that module to fail.
5824
Nick Coghlan14ff9942008-07-08 14:21:42 +00005825- Issue #2517: Allow unicode messages in Exceptions again by correctly

5835 another thread's dictionary.
5836
Mark Dickinson1ec2fcd2008-06-20 14:53:43 +00005837- Issue #3004: Minor change to slice.indices(): the start and stop
5838 arguments are now treated identically, making the behaviour easier
5839 to describe and understand. For example, slice(None, -10,
5840 1).indices(9) now returns (0, 0, 1) instead of (0, -1, 1), and
5841 slice(None, 10, -1).indices(10) returns (9, 9, -1) instead of (9,
5842 10, -1).
5843
Georg Brandl278fc502008-07-19 12:46:12 +00005844- Issue #3219: Calling a function with repeated keyword arguments,
5845 f(a=2, a=23), would not cause a syntax error. This was a regression
5846 from 2.4 caused by the switch to the new compiler.

Georg Brandl278fc502008-07-19 12:46:12 +00005848- Issue #2862: Make int and float freelist management consistent with
5849 other freelists. Changes their CompactFreeList apis into

5856 api functions without holding the GIL, which could lead to a fatal
5857 error when they failed.
5858
Martin v. Löwisaabf4042008-08-02 07:20:25 +00005859- Issue #799428: Fix Tkinter.Misc._nametowidget to unwrap Tcl command objects.

Amaury Forgeot d'Arc0f7cddc2008-07-06 21:34:39 +00005884- Issue #839496: SimpleHTTPServer used to open text files in text mode. This is
5885 both unnecessary (HTTP allows text content to be sent in several forms) and
Andrew M. Kuchlingcc3f2b12008-07-10 14:43:31 +00005886 wrong because the actual transmitted size could differ from the
Amaury Forgeot d'Arc0f7cddc2008-07-06 21:34:39 +00005887 content-length. The problem had been corrected in the 2.4 branch, but never

Nick Coghlanc060b0e2008-07-02 13:09:19 +00005903- Issue #3190: Pydoc now hides the automatic module attribute __package__ (the

6247 suitable sign) if n is large and negative; previously, it raised
6248 OverflowError.

Ronald Oussoren5640ce22008-06-05 12:58:24 +00006294- On MacOS X it is now possible to install the framework in 64-bit
6295 mode or even as a 4-way universal binary (that is, PPC, i386,
Georg Brandl5cc774e2008-06-11 20:28:06 +00006296 PPC64 and x86_64 support in one binary).
Ronald Oussoren5640ce22008-06-05 12:58:24 +00006297
6298 This is controlled by the configure argument ``--with-universal-archs``:
6299
6300 - ``--with-universal-archs=all``: install 4-way universal
6301
6302 - ``--with-universal-archs=32-bit``: install 2-way universal, 32-bit (the default)
6303
6304 - ``--with-universal-archs=64-bit``: install 2-way universal, 64-bit
6305
6306 This option should be used in combination with ``--enable-universalsdk=``.
6307
6308 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 +00006358- Issue #1631171: Re-implement the 'warnings' module in C (the
6359 original Python code has been kept as backup). This will allow for
6360 using the 'warning's machinery in such places as the parser where
6361 use of pure Python code is not possible. Both the ``showarning()``
6362 and ``formatwarning()`` gain an optional 'line' argument which is
6363 not called by default for backwards-compatibility reasons. Setting
6364 ``warnings.showwarning()`` to an implementation that lacks support
6365 for the ``line`` argument will raise a DeprecationWarning.

Georg Brandl3ee81df2008-05-17 18:14:43 +00006428- Issue #2550: The approach used by client/server code for obtaining
6429 ports to listen on in network-oriented tests has been refined in an
6430 effort to facilitate running multiple instances of the entire
6431 regression test suite in parallel without issue.
6432 test_support.bind_port() has been fixed such that it will always
6433 return a unique port -- which wasn't always the case with the
6434 previous implementation, especially if socket options had been set
6435 that affected address reuse (i.e. SO_REUSEADDR, SO_REUSEPORT). The
6436 new implementation of bind_port() will actually raise an exception
6437 if it is passed an AF_INET/SOCK_STREAM socket with either the
6438 SO_REUSEADDR or SO_REUSEPORT socket option set. Furthermore, if
6439 available, bind_port() will set the SO_EXCLUSIVEADDRUSE option on
6440 the socket it's been passed. This currently only applies to
6441 Windows. This option prevents any other sockets from binding to the
6442 host/port we've bound to, thus removing the possibility of the
6443 'non-deterministic' behaviour, as Microsoft puts it, that occurs
6444 when a second SOCK_STREAM socket binds and accepts to a host/port
6445 that's already been bound by another socket. The optional preferred
6446 port parameter to bind_port() has been removed. Under no
6447 circumstances should tests be hard coding ports!
6448
6449 test_support.find_unused_port() has also been introduced, which will
6450 pass a temporary socket object to bind_port() in order to obtain an
6451 unused port. The temporary socket object is then closed and
6452 deleted, and the port is returned. This method should only be used
6453 for obtaining an unused port in order to pass to an external program
6454 (i.e. the -accept [port] argument to openssl's s_server mode) or as
6455 a parameter to a server-oriented class that doesn't give you direct
6456 access to the underlying socket used.
6457
6458 Finally, test_support.HOST has been introduced, which should be used
6459 for the host argument of any relevant socket calls (i.e. bind and
6460 connect).
Trent Nelsone41b0062008-04-08 23:47:30 +00006461
6462 The following tests were updated to following the new conventions:
Georg Brandl3ee81df2008-05-17 18:14:43 +00006463 test_socket, test_smtplib, test_asyncore, test_ssl, test_httplib,
Trent Nelsone41b0062008-04-08 23:47:30 +00006464 test_poplib, test_ftplib, test_telnetlib, test_socketserver,
6465 test_asynchat and test_socket_ssl.
6466
Georg Brandl3ee81df2008-05-17 18:14:43 +00006467 It is now possible for multiple instances of the regression test
6468 suite to run in parallel without issue.

Amaury Forgeot d'Arc9a0d3462008-03-23 09:55:29 +00006522- Issue #1477: With narrow Unicode builds, the unicode escape sequence
Georg Brandl3ee81df2008-05-17 18:14:43 +00006523 \Uxxxxxxxx did not accept values outside the Basic Multilingual
6524 Plane. This affected raw unicode literals and the
6525 'raw-unicode-escape' codec. Now UTF-16 surrogates are generated in
6526 this case, like normal unicode literals and the 'unicode-escape'
6527 codec.

Eric Smitha73fbe72008-02-23 03:09:44 +00006747- Added the future_builtins module, which contains hex() and oct().
6748 These are the PEP 3127 version of these functions, designed to be
6749 compatible with the hex() and oct() builtins from Python 3.0. They
6750 differ slightly in their output formats from the existing, unchanged
6751 Python 2.6 builtins. The expected usage of the future_builtins
6752 module is:
6753 from future_builtins import hex, oct
6754
Eric Smith7ef40bf2008-02-20 23:34:22 +00006755- Issue #1600: Modifed PyOS_ascii_formatd to use at most 2 digit
6756 exponents for exponents with absolute value < 100. Follows C99
6757 standard. This is a change on Windows, which would use 3 digits.
6758 Also, added 'n' to the formats that PyOS_ascii_formatd understands,
6759 so that any alterations it does to the resulting string will be
6760 available in stringlib/formatter.h (for float.__format__).
6761
Eric Smith5a3c1352008-02-19 13:21:56 +00006762- Implemented PEP 3101, Advanced String Formatting. This adds a new
6763 builtin format(); a format() method for str and unicode; a
6764 __format__() method to object, str, unicode, int, long, float, and
6765 datetime; the class string.Formatter; and the C API
6766 PyObject_Format().
6767
Georg Brandl3ee81df2008-05-17 18:14:43 +00006768- Fixed several potential crashes, all caused by specially crafted
6769 __del__ methods exploiting objects in temporarily inconsistent
6770 state.
Amaury Forgeot d'Arc632fad32008-02-16 20:55:24 +00006771
Vinay Sajipb7edfc42008-04-02 21:10:23 +00006772- Issue #2115: Important speedup in setting __slot__ attributes. Also
Georg Brandl3ee81df2008-05-17 18:14:43 +00006773 prevent a possible crash: an Abstract Base Class would try to access
6774 a slot on a registered virtual subclass.
Amaury Forgeot d'Arc60d6c7f2008-02-15 21:22:45 +00006775

Georg Brandl3ee81df2008-05-17 18:14:43 +00006779- Clear all free lists during a gc.collect() of the highest generation
6780 in order to allow pymalloc to free more arenas. Python may give back
6781 memory to the OS earlier.
Christian Heimes3b718a72008-02-14 12:47:33 +00006782
Georg Brandl3ee81df2008-05-17 18:14:43 +00006783- Issue #2045: Fix an infinite recursion triggered when printing a
6784 subclass of collections.defaultdict, if its default_factory is set
6785 to a bound method.
Amaury Forgeot d'Arcb01aa432008-02-08 00:56:02 +00006786
Christian Heimesf75dbef2008-02-08 00:11:31 +00006787- Fixed a minor memory leak in dictobject.c. The content of the free
6788 list was not freed on interpreter shutdown.

Georg Brandl21e99f42010-03-07 15:23:59 +00006790- Limit free list of method and built-in function objects to 256
Georg Brandl3ee81df2008-05-17 18:14:43 +00006791 entries each.
Christian Heimes6075a822008-02-06 12:44:34 +00006792
Georg Brandl3ee81df2008-05-17 18:14:43 +00006793- Patch #1953: Added ``sys._compact_freelists()`` and the C API
6794 functions ``PyInt_CompactFreeList`` and ``PyFloat_CompactFreeList``
Christian Heimes422051a2008-02-04 18:00:12 +00006795 to compact the internal free lists of pre-allocted ints and floats.
6796
Georg Brandl3ee81df2008-05-17 18:14:43 +00006797- Issue #1983: Fixed return type of fork(), fork1() and forkpty()
6798 calls. Python expected the return type int but the fork familie
6799 returns pi_t.

Georg Brandl3ee81df2008-05-17 18:14:43 +00006813- Patch #1473257: generator objects gain a gi_code attribute. This is
6814 the same object as the func_code attribute of the function that
6815 produced the generator.
Georg Brandl0cdf9a32008-01-26 14:14:20 +00006816
Georg Brandl3ee81df2008-05-17 18:14:43 +00006817- Issue #1920: "while 0" statements were completely removed by the
6818 compiler, even in the presence of an "else" clause, which is
6819 supposed to be run when the condition is false. Now the compiler
6820 correctly emits bytecode for the "else" suite.
Amaury Forgeot d'Arc31eaafe2008-01-24 22:59:25 +00006821
Guido van Rossumeead05f2008-01-24 18:21:02 +00006822- A few crashers fixed: weakref_in_del.py (issue #1377858);
6823 loosing_dict_ref.py (issue #1303614, test67.py);
6824 borrowed_ref_[34].py (not in tracker).
6825
Vinay Sajipd7cf32e2008-01-24 12:43:33 +00006826- Issue #1069410: The "can't load dll" message box on Windows is
Christian Heimesb2302ba2008-01-23 17:15:06 +00006827 suppressed while an extension is loaded by calling SetErrorMode in
6828 dynload_win.c. The error is still reported properly.
6829
Georg Brandl3ee81df2008-05-17 18:14:43 +00006830- Issue #1915: Python compiles with --enable-unicode=no again. However
Christian Heimes082c9b02008-01-23 14:20:50 +00006831 several extension methods and modules do not work without unicode
6832 support.
6833
Georg Brandl26543b12008-01-21 18:36:51 +00006834- Issue #1882: when compiling code from a string, encoding cookies in the

6838
Georg Brandl6caad7d2008-01-26 14:19:22 +00006839- Issue #1865: ``bytes`` as an alias for ``str`` and b"" as an alias "" were
Christian Heimes288e89a2008-01-18 18:24:07 +00006840 added.
6841
Christian Heimesc94e2b52008-01-14 04:13:37 +00006842- sys.float_info / PyFloat_GetInfo: The floating point information
6843 object was converted from a dict to a specialized structseq object.
6844
Georg Brandl3ee81df2008-05-17 18:14:43 +00006845- Patch #1816: Added sys.flags structseq. It exposes the status of
6846 most command line arguments and PYTHON* environment variables.
Christian Heimesf31b69f2008-01-14 03:42:48 +00006847
Georg Brandl3ee81df2008-05-17 18:14:43 +00006848- Objects/structseq.c: Implemented new structseq representation. The
6849 patch makes structseqs (e.g. the return value of os.stat) more
6850 readable.
Christian Heimes9c201962008-01-14 03:33:52 +00006851
Georg Brandl3ee81df2008-05-17 18:14:43 +00006852- Patch #1700288: added a type attribute cache that caches method
6853 accesses, resulting in speedups in heavily object-oriented code.
Amaury Forgeot d'Arce4c270c2008-01-14 00:29:41 +00006854
Neal Norwitz3fc15b82008-01-10 05:42:58 +00006855- Bug #1776: __import__() no longer accepts filenames on any platform.

6861 envvar and sys.dont_write_bytecode attribute. All these can be set
6862 to forbid Python to attempt to write compiled bytecode files.
Georg Brandl2da0fce2008-01-07 17:09:35 +00006863
Georg Brandl3ee81df2008-05-17 18:14:43 +00006864- Improve some exception messages when Windows fails to load an
6865 extension module. Now we get for example '%1 is not a valid Win32
6866 application' instead of 'error code 193'.

Christian Heimes0a8143f2007-12-18 23:22:54 +00006873- Issue #1635: Platform independent creation and representation of NaN
Georg Brandl3ee81df2008-05-17 18:14:43 +00006874 and INF. float("nan"), float("inf") and float("-inf") now work on
6875 every platform with IEEE 754 semantics.
Christian Heimes0a8143f2007-12-18 23:22:54 +00006876
Georg Brandl3ee81df2008-05-17 18:14:43 +00006877- Compiler now generates simpler and faster code for dictionary
6878 literals. The oparg for BUILD_MAP now indicates an estimated
6879 dictionary size. There is a new opcode, STORE_MAP, for adding
6880 entries to the dictionary.

Georg Brandl3ee81df2008-05-17 18:14:43 +00006909- Patch #1739468: Directories and zipfiles containing a __main__.py
6910 file can now be directly executed by passing their name to the
6911 interpreter. The directory/zipfile is automatically inserted as the
6912 first entry in sys.path.
Nick Coghlan327a39b2007-11-18 11:56:28 +00006913
Georg Brandl3ee81df2008-05-17 18:14:43 +00006914- Issue #1265: Fix a problem with sys.settrace, if the tracing
6915 function uses a generator expression when at the same time the
6916 executed code is closing a paused generator.
Amaury Forgeot d'Arc0d75f092007-11-13 21:54:28 +00006917
Raymond Hettinger1760c8a2007-11-08 02:52:43 +00006918- sets and frozensets now have an isdisjoint() method.
6919
Raymond Hettinger3f8caa32007-10-24 01:28:33 +00006920- optimize the performance of builtin.sum().

6923
Georg Brandl21e99f42010-03-07 15:23:59 +00006924- The enumerate() built-in function is no longer bounded to sequences
Georg Brandl3ee81df2008-05-17 18:14:43 +00006925 smaller than LONG_MAX. Formerly, it raised an OverflowError. Now,
6926 automatically shifts from ints to longs.
Raymond Hettinger8f669372007-10-03 21:18:11 +00006927
Georg Brandl3ee81df2008-05-17 18:14:43 +00006928- Issue #1686386: Tuple's tp_repr did not take into account the
6929 possibility of having a self-referential tuple, which is possible
6930 from C code. Nor did object's tp_str consider that a type's tp_str
6931 could do something that could lead to an inifinite recursion.
6932 Py_ReprEnter() and Py_EnterRecursiveCall(), respectively, fixed the
6933 issues.
Brett Cannon0b14f242007-09-30 19:45:10 +00006934
Georg Brandl3ee81df2008-05-17 18:14:43 +00006935- Issue #1164: It was possible to trigger deadlock when using the
6936 'print' statement to write to a file since the GIL was not released
6937 as needed. Now PyObject_Print() does the right thing along with
6938 various tp_print implementations of the built-in types and those in
6939 the collections module.
Brett Cannon01531592007-09-17 03:28:34 +00006940
Georg Brandl3ee81df2008-05-17 18:14:43 +00006941- Issue #1147: Exceptions were directly allowing string exceptions in
6942 their throw() method even though string exceptions no longer
6943 allowed.
Brett Cannon4c20bc42007-09-11 21:02:28 +00006944
Georg Brandl3ee81df2008-05-17 18:14:43 +00006945- Issue #1096: Prevent a segfault from getting the repr of a very

Brett Cannona0c05512007-09-10 21:38:27 +00006947
Brett Cannon1e534b52007-09-07 04:18:30 +00006948- Issue #1202533: Fix infinite recursion calls triggered by calls to
Georg Brandl3ee81df2008-05-17 18:14:43 +00006949 PyObject_Call() never calling back out to Python code to trigger
6950 recursion depth updates/checks. Required the creation of a static
6951 RuntimeError instance in case normalizing an exception put the
6952 recursion check value past its limit. Fixes crashers
6953 infinite_rec_(1|2|4|5).py.
Brett Cannon1e534b52007-09-07 04:18:30 +00006954

Georg Brandl3ee81df2008-05-17 18:14:43 +00006969 __*__ attributes. (Some already existed, e.g., __doc__ and
6970 __name__.)

6976 calls.
6977
Collin Winter62903052007-05-18 23:11:24 +00006978- except clauses may now be spelled either "except E, target:" or
Georg Brandl3ee81df2008-05-17 18:14:43 +00006979 "except E as target:". This is to provide forwards compatibility
6980 with Python 3.0.

Georg Brandl3ee81df2008-05-17 18:14:43 +00006984- Issue #1303614: don't expose object's __dict__ when the dict is
Georg Brandl21e99f42010-03-07 15:23:59 +00006985 inherited from a built-in base.
Armin Rigo9790a272007-05-02 19:23:31 +00006986
Vinay Sajip8549ce32007-05-06 17:53:37 +00006987- When __slots__ are set to a unicode string, make it work the same as
Neal Norwitzcbd9ee62007-04-14 05:25:50 +00006988 setting a plain string, ie don't expand to single letter identifiers.
6989
Raymond Hettinger13936692007-04-11 18:40:58 +00006990- Request #1191699: Slices can now be pickled.
6991
Raymond Hettinger4db5fe92007-04-12 04:10:00 +00006992- Request #1193128: str.translate() now allows a None argument for
6993 translations that only remove characters without re-mapping the
6994 remaining characters.
6995
Georg Brandl5cb76c12007-03-21 09:00:39 +00006996- Patch #1682205: a TypeError while unpacking an iterable is no longer

7000
Guido van Rossum143b5642007-03-23 04:58:42 +00007001- Bug #1683368: The object.__init__() and object.__new__() methods are
7002 now stricter in rejecting excess arguments. The only time when
7003 either allows excess arguments is when it is not overridden and the
7004 other one is. For backwards compatibility, when both are
7005 overridden, it is a deprecation warning (for now; maybe a Py3k
Guido van Rossum234b1ff2007-03-23 19:39:01 +00007006 warning later). Also, type.__init__() insists on the same signature
7007 as supported by type.__new__().

Georg Brandl3ee81df2008-05-17 18:14:43 +00007009- Patch #1675423: PyComplex_AsCComplex() now tries to convert an
7010 object to complex using its __complex__() method before falling back
7011 to the __float__() method. Therefore, the functions in the cmath
7012 module now can operate on objects that define a __complex__()
7013 method.

7033
Georg Brandl871f1bc2007-03-12 13:17:36 +00007034- The dir() function has been extended to call the __dir__() method on
Georg Brandl3ee81df2008-05-17 18:14:43 +00007035 its argument, if it exists. If not, it will work like before. This
7036 allows customizing the output of dir() in the presence of a
7037 __getattr__().

Georg Brandlaa2321b2007-03-07 00:40:28 +00007049- Patch #703779: unset __file__ in __main__ after running a file. This
Georg Brandl3ee81df2008-05-17 18:14:43 +00007050 makes the filenames the warning module prints much more sensible
7051 when a PYTHONSTARTUP file is used.

7066
Georg Brandl3ee81df2008-05-17 18:14:43 +00007067- When printing an unraisable error, don't print exceptions. before

Georg Brandl2c1375c2006-10-12 11:27:59 +00007119- Bug #1545497: when given an explicit base, int() did ignore NULs
7120 embedded in the string to convert.
7121
Georg Brandl846f73a2006-10-08 07:11:54 +00007122- Bug #1569998: break inside a try statement (outside a loop) is now

Georg Brandl3ee81df2008-05-17 18:14:43 +00007170 generator expressions (x for x, in ... ) works again. Fixing this
7171 problem required changing the .pyc magic number. This means that
7172 .pyc files generated before 2.5c2 will be regenerated.

Georg Brandl3ee81df2008-05-17 18:14:43 +00007975- The implementation of UnicodeError objects has been simplified
7976 (start and end attributes are now stored directly as Py_ssize_t
7977 members).
Walter Dörwald84a3efe2007-06-13 16:57:12 +00007978
Georg Brandl3ee81df2008-05-17 18:14:43 +00007979- Issue #829951: In the smtplib module, SMTP.starttls() now complies
7980 with RFC 3207 and forgets any knowledge obtained from the server not
7981 obtained from the TLS negotiation itself. Patch contributed by Bill
7982 Fenner.
Gregory P. Smith2b3ba582008-01-17 08:03:17 +00007983
Georg Brandl3ee81df2008-05-17 18:14:43 +00007984- Issue #1339: The smtplib.SMTP class has been refactored a bit such
Gregory P. Smithbde4ae42008-01-17 08:35:49 +00007985 that the SMTP.starttls() caller no longer needs to call ehlo()
7986 beforehand. SMTP.starttls() now raises an exception of the server
Georg Brandl3ee81df2008-05-17 18:14:43 +00007987 does not claim to support starttls. Adds the
7988 SMTP.ehlo_or_helo_if_needed() method. Patch contributed by Bill
7989 Fenner.

8069 complex, tuple, list, dict, set, and frozenset. Formerly, it would
8070 silently miscode subclasses of those types. Now, it raises a
8071 ValueError instead.
Raymond Hettinger12e94202007-11-07 01:13:09 +00008072

Georg Brandl3ee81df2008-05-17 18:14:43 +00008087 time so that opening a database previously created with the DB_DUP
8088 or DB_DUPSORT flag set will keep the proper behavior on subsequent
8089 opens. Specifically: dictionary assignment to a DB object will
8090 replace all values for a given key when the database allows
8091 duplicate values. DB users should use DB.put(k, v) when they want
8092 to store duplicates; not DB[k] = v.
Gregory P. Smithec10a4a2007-11-05 02:32:26 +00008093

8099 characters with ASCII value less than 32. Also, it correctly quotes
8100 dots only if they occur on a single line, as opposed to the previous
8101 behavior of quoting dots if they are the second character of any
8102 line.
Georg Brandl4aef7272007-03-13 22:49:43 +00008103
