Mark Dickinsondbbed042011-09-19 16:38:08 +0100337- Issue #12973: Fix overflow checks that invoked undefined behaviour in

339 incorrect results with recent versions of Clang, as a result of the
Mark Dickinsona96b0d12011-09-24 09:01:16 +0100340 compiler optimizing the check away. Also fix similar overflow checks
341 in list_repeat (listobject.c) and islice_next (itertoolsmodule.c). These

Ned Deilyc47a4592012-02-11 20:40:24 +0100411 has left two versions of customize_compiler, the original in
412 distutils.sysconfig and another copy in distutils.ccompiler, with some

Ned Deily0d0ea482012-02-10 12:59:06 +0100417- Issue #13590: On OS X 10.7 and 10.6 with Xcode 4.2, building
418 Distutils-based packages with C extension modules may fail because
419 Apple has removed gcc-4.2, the version used to build python.org
420 64-bit/32-bit Pythons. If the user does not explicitly override
421 the default C compiler by setting the CC environment variable,
422 Distutils will now attempt to compile extension modules with clang
423 if gcc-4.2 is required but not found. Also as a convenience, if
424 the user does explicitly set CC, substitute its value as the default
425 compiler in the Distutils LDSHARED configuration variable for OS X.
426 (Note, the python.org 32-bit-only Pythons use gcc-4.0 and the 10.4u
427 SDK, neither of which are available in Xcode 4. This change does not
428 attempt to override settings to support their use with Xcode 4.)

Ned Deily87e82bb2011-06-28 19:52:59 -0700701- Issue #9516: On Mac OS X, change Distutils to no longer globally attempt to
702 check or set the MACOSX_DEPLOYMENT_TARGET environment variable for the
703 interpreter process. This could cause failures in non-Distutils subprocesses
704 and was unreliable since tests or user programs could modify the interpreter
705 environment after Distutils set it. Instead, have Distutils set the the
706 deployment target only in the environment of each build subprocess. It is
707 still possible to globally override the default by setting
708 MACOSX_DEPLOYMENT_TARGET before launching the interpreter; its value must be
709 greater or equal to the default value, the value with which the interpreter
710 was built.

740 the ticker doesn't have to wind down to zero from the old starting point
741 before the new interval takes effect. And if the user increases the
742 interval, it makes sure the new limit takes effect right away rather have an
743 early task switch before recognizing the new interval.

1690
Raymond Hettinger20397532010-09-12 02:11:45 +00001691- Issue #9825: removed __del__ from the definition of collections.OrderedDict.
1692 This prevents user-created self-referencing ordered dictionaries from
1693 becoming permanently uncollectable GC garbage. The downside is that
1694 removing __del__ means that the internal doubly-linked list has to wait for
1695 GC collection rather than freeing memory immediately when the refcnt drops
1696 to zero.

1701
Antoine Pitrouc818ed42010-09-07 21:40:25 +00001702- Issue #9792: In case of connection failure, socket.create_connection()

1704 to fetch the original errno, or to filter timeout errors. Now the
1705 original error is re-raised.

1726
R. David Murray7c4bf552010-08-25 01:45:57 +00001727- Issue #1194222: email.utils.parsedate now returns RFC2822 compliant four
1728 character years even if the message contains RFC822 two character years.

Ezio Melottiab2eb0e2010-06-05 19:21:32 +00002155- Issue #8271: during the decoding of an invalid UTF-8 byte sequence, only the
2156 start byte and the continuation byte(s) are now considered invalid, instead
2157 of the number of bytes specified by the start byte.
2158 E.g.: '\xf1\x80AB'.decode('utf-8', 'replace') now returns u'\ufffdAB' and
2159 replaces with U+FFFD only the start byte ('\xf1') and the continuation byte
2160 ('\x80') even if '\xf1' is the start byte of a 4-bytes sequence.

Mark Dickinson4ca7c3c2010-05-30 13:18:10 +00002169- Issue #8748: Fix two issues with comparisons between complex and integer
2170 objects. (1) The comparison could incorrectly return True in some cases
2171 (2**53+1 == complex(2**53) == 2**53), breaking transivity of equality.
2172 (2) The comparison raised an OverflowError for large integers, leading

Mark Dickinson81336372010-05-30 12:12:25 +00002176- Issue #5211: Implicit coercion for the complex type is now completely

2557 with a non-empty format string. This is an effort to future-proof user
2558 code. If a derived class does not currently implement __format__ but later

3036 XML processing instructions and comments. These raw characters are allowed
3037 by the XML specification, and are necessary when outputting e.g. PHP code in
3038 a processing instruction. Patch by Neil Muller.

Antoine Pitroud840e512010-02-04 20:20:18 +00003046- Issue #4772: Raise a ValueError when an unknown Bluetooth protocol is
Georg Brandlba83f822010-03-14 09:50:54 +00003047 specified, rather than fall through to AF_PACKET (in the ``socket`` module).
Antoine Pitroud840e512010-02-04 20:20:18 +00003048 Also, raise ValueError rather than TypeError when an unknown TIPC address
3049 type is specified. Patch by Brian Curtin.
3050
Vinay Sajip28c382f2010-02-04 18:48:53 +00003051- logging: Implemented PEP 391.

Antoine Pitrouf3fa0742010-01-31 22:26:04 +00003053- Issue #6939: Fix file I/O objects in the `io` module to keep the original
Georg Brandlba83f822010-03-14 09:50:54 +00003054 file position when calling `truncate()`. It would previously change the file
3055 position to the given argument, which goes against the tradition of
Antoine Pitrouf3fa0742010-01-31 22:26:04 +00003056 ftruncate() and other truncation APIs. Patch by Pascal Chambon.
3057
Georg Brandlba83f822010-03-14 09:50:54 +00003058- Issue #7610: Reworked implementation of the internal ``zipfile.ZipExtFile``
3059 class used to represent files stored inside an archive. The new
3060 implementation is significantly faster and can be wrapped in a
3061 ``io.BufferedReader`` object for more speedups. It also solves an issue
3062 where interleaved calls to ``read()`` and ``readline()`` give wrong results.
3063 Patch by Nir Aides.

Benjamin Petersona43f34c2010-01-25 03:31:13 +00003072
Georg Brandlba83f822010-03-14 09:50:54 +00003073- Issue #7748: Since unicode values are supported for some metadata options in
3074 Distutils, the DistributionMetadata get_* methods will now return an utf-8
3075 encoded string for them. This ensures that the upload and register commands
3076 send the correct values to PyPI without any error.

3151-----------------
3152
Georg Brandlba83f822010-03-14 09:50:54 +00003153- The ``__complex__()`` method is now looked up on the class of instances to
3154 make it consistent with other special methods.

Antoine Pitrou5b7139a2010-01-02 21:12:58 +00003156- Issue #7462: Implement the stringlib fast search algorithm for the `rfind`,
3157 `rindex`, `rsplit` and `rpartition` methods. Patch by Florent Xicluna.
3158
Mark Dickinson1b34d252010-01-01 17:27:30 +00003159- Issue #5080: A number of functions and methods previously produced a
Georg Brandlba83f822010-03-14 09:50:54 +00003160 DeprecationWarning when passed a float argument where an integer was expected.
3161 These functions and methods now raise TypeError instead. The majority of the
3162 effects of this change are in the extension modules, but some core functions
3163 and methods are affected: notably the 'chr', 'range' and 'xrange' builtins,
3164 and many unicode/str methods.

3178 of integers: the result of a/b is now correctly rounded for ints a and b (at
3179 least on IEEE 754 platforms), and in particular does not depend on the
3180 internal representation of a long.

Ronald Oussoren92919a62009-12-24 13:30:58 +00003187 executables on OSX.
3188
Georg Brandlba83f822010-03-14 09:50:54 +00003189 These executables now work properly with the arch(1) command: ``arch -ppc
3190 python`` will start a universal binary version of python in PPC mode (unlike
3191 previous releases).

Georg Brandlba83f822010-03-14 09:50:54 +00003214 renaming of `cPickle` to `pickle`. The warning was annoying since there's no

3331 to 'g' for large values.
Amaury Forgeot d'Arcd7288712009-12-01 21:51:04 +00003332

3334 1e50 in absolute value.

Ronald Oussoren315cd0c2009-11-19 16:25:21 +00003346
Georg Brandlba83f822010-03-14 09:50:54 +00003347- Issue #7117: ``repr(x)`` for a float x returns a result based on the shortest
3348 decimal string that's guaranteed to round back to x under correct rounding
3349 (with round-half-to-even rounding mode). Previously it gave a string based on
3350 rounding x to 17 decimal digits. repr(x) for a complex number behaves
3351 similarly. On platforms where the correctly-rounded strtod and dtoa code is
3352 not supported (see below), repr is unchanged.
Mark Dickinsonb678de82009-11-19 18:41:49 +00003353
Georg Brandlba83f822010-03-14 09:50:54 +00003354- Issue #7117: On almost all platforms: float-to-string and string-to-float
3355 conversions within Python are now correctly rounded. Places these conversions
3356 occur include: str for floats and complex numbers; the float and complex
3357 constructors; old-style and new-style numeric formatting; serialization and
3358 deserialization of floats and complex numbers using marshal, pickle and json;
3359 parsing of float and imaginary literals in Python code; Decimal-to-float
3360 conversion.
Mark Dickinsonb678de82009-11-19 18:41:49 +00003361
Georg Brandlba83f822010-03-14 09:50:54 +00003362 The conversions use a Python-adapted version of David Gay's well-known dtoa.c,
3363 providing correctly-rounded strtod and dtoa C functions. This code is
3364 supported on Windows, and on Unix-like platforms using gcc, icc or suncc as
3365 the C compiler. There may be a small number of platforms on which correct
3366 operation of this code cannot be guaranteed, so the code is not used: notably,
3367 this applies to platforms where the C double format is not IEEE 754 binary64,
3368 and to platforms on x86 hardware where the x87 FPU is set to 64-bit precision
3369 and Python's configure script is unable to determine how to change the FPU
3370 precision. On these platforms conversions use the platform strtod and dtoa,
3371 as before.
Mark Dickinsonb678de82009-11-19 18:41:49 +00003372
Georg Brandlba83f822010-03-14 09:50:54 +00003373- Issue #7117: Backport round implementation from Python 3.x. ``round()`` now
3374 uses the correctly-rounded string <-> float conversions described above (when
3375 available), and so produces correctly rounded results that will display nicely
3376 under the float repr. There are two related small changes: (1) round now
3377 accepts any class with an ``__index__()`` method for its second argument (but
3378 no longer accepts floats for the second argument), and (2) an excessively
3379 large second integer argument (e.g., ``round(1.234, 10**100)``) no longer
3380 raises an exception.

Mark Dickinsonb1d45852009-05-11 15:33:08 +00003522
Georg Brandlba83f822010-03-14 09:50:54 +00003523 (1) inf and nan strings with trailing whitespace were incorrectly rejected;
3524 (2) parsing of strings representing infinities and nans was locale aware; and
3525 (3) the interpretation of fromhex('-nan') didn't match that of float('-nan').

Georg Brandlba83f822010-03-14 09:50:54 +00003527- Issue #5920: For ``float.__format__()``, change the behavior with the empty
3528 presentation type (that is, not one of 'e', 'f', 'g', or 'n') to be like 'g'
3529 but with at least one decimal point and with a default precision
3530 of 12. Previously, the behavior the same but with a default precision of 6.
3531 This more closely matches ``str()``, and reduces surprises when adding
3532 alignment flags to the empty presentation type. This also affects the new
3533 complex.__format__ in the same way.
3534
3535- Issue #5890: In subclasses of 'property' the __doc__ attribute was shadowed by

3732 file objects with closefd=False. The file descriptor is still kept open but
3733 the file object behaves like a closed file. The ``FileIO`` object also got a
3734 new readonly attribute ``closefd``.

3786 PyUnicode_DecodeUTF8() once, remember the result and output it in a second

4963 __long__ method could be packed by 'q', 'Q', '*q', '*Q'; for x with
4964 neither __int__ nor __long__, TypeError used to be raised (with a

Martin v. Löwis9fa5a282008-09-11 06:53:30 +00005161- Issue #3642: Suppress warning in obmalloc when size_t is larger than uint.
5162
Amaury Forgeot d'Arc05e34492008-09-10 22:04:45 +00005163- Issue #3743: In a few places, PY_FORMAT_SIZE_T was incorrectly used with
5164 PyString_FromFormat or PyErr_Format to display size_t values. The macro
5165 PY_FORMAT_SIZE_T is designed to select the correct format for the OS
5166 ``printf`` function, whereas PyString_FromFormat has an independent
5167 implementation and uses "%zd" on all platforms for size_t values.
5168 This makes a difference on win64, where ``printf`` needs "%Id" to display
5169 64bit values.
5170
Benjamin Peterson97179b02008-09-09 20:55:01 +00005171- Issue #3634: _weakref.ref(Exception).__init__() gave invalid return value on
5172 error.
5173
Amaury Forgeot d'Arcd3ffb892008-09-09 07:24:30 +00005174- Issue #3777: long() applied to a float object now always return a long
5175 object; previously an int would be returned for small values. the __long__
5176 method is allowed to return either an int or a long, but the behaviour of
5177 float objects should not change to respect backward compatibility.
5178
Amaury Forgeot d'Arc3571fbf2008-09-01 19:52:00 +00005179- Issue #3751: str.rpartition would perform a left-partition when called with
5180 a unicode argument.

Vinay Sajip35e3b032008-09-01 14:33:59 +00005185 PyArg_ParseTuple and friends, which occurred when the argument for "s*"
Antoine Pitroud4ae97b2008-08-29 18:39:48 +00005186 was correctly parsed but parsing of subsequent arguments failed.
5187
Vinay Sajip35e3b032008-09-01 14:33:59 +00005188- Issue #2534: speed up isinstance() and issubclass() by 50-70%, so as to
Antoine Pitrou0668c622008-08-26 22:42:08 +00005189 match Python 2.5 speed despite the __instancecheck__ / __subclasscheck__
5190 mechanism. In the process, fix a bug where isinstance() and issubclass(),
5191 when given a tuple of classes as second argument, were looking up
5192 __instancecheck__ / __subclasscheck__ on the tuple rather than on each
5193 type object.
5194
Neal Norwitz18aa3882008-08-24 05:04:52 +00005195- Fix crashes on memory allocation failure found with failmalloc.

Brett Cannon1eaf0742008-09-02 01:25:16 +00005264 warnings.catch_warnings() along with some API cleanup. Expanding the tests
5265 for catch_warnings() also led to an improvement in the raising of a

5338-----------------
5339
Guido van Rossumf8402962008-08-20 15:01:50 +00005340- Issue #1878: Remove Py_TPFLAGS_HAVE_VERSION_TAG from
5341 Py_TPFLAGS_DEFAULT when not building the core. This means 3rd party
5342 extensions do not automatically benefit from the class attribute
5343 cache; they will have to explicitly add Py_TPFLAGS_HAVE_VERSION_TAG
5344 to their tp_flags field if they care. This is a backwards
5345 compatibility feature; in 3.0, all types will use the cache by
5346 default.
5347
Benjamin Petersonf647dc12008-08-20 01:27:30 +00005348- Keyword arguments can now follow starred arguments. (``f(a, *args,
5349 keyword=23)`` is now valid syntax.)
5350
Thomas Heller0ad5ae02008-08-19 19:25:04 +00005351- ctypes function pointers that are COM methods have a boolean True
5352 value again.
5353
Martin v. Löwisf91d46a2008-08-12 14:49:50 +00005354- Issue #3139: Make buffer-interface thread-safe wrt. PyArg_ParseTuple,
5355 by denying s# to parse objects that have a releasebuffer procedure,
5356 and introducing s*.
5357
Georg Brandl1e13ea92008-08-11 09:07:59 +00005358- Issue #3537: Fix an assertion failure when an empty but presized dict
5359 object was stored in the freelist.
5360
Mark Dickinsonb6467572008-08-04 21:30:09 +00005361- Issue #1481296: Make long(float('nan')) and int(float('nan')) raise
5362 ValueError consistently across platforms.
5363
Amaury Forgeot d'Arc39fd6722008-07-31 21:28:03 +00005364- Issue #3479: On platforms where sizeof(int) is smaller than sizeof(long)
5365 (64bit Unix, for example), unichr() would truncate its argument and return
5366 u'\x00' for unichr(2**32). Now it properly raises an OverflowError.
5367
Neal Norwitze7d8be82008-07-31 17:17:14 +00005368- Apply security patches from Apple.
5369
Amaury Forgeot d'Arc246daed2008-07-31 00:42:16 +00005370- Issue #2542: Now that issubclass() may call arbitrary code, ensure that
5371 PyErr_ExceptionMatches returns 0 when an exception occurs there.
5372
Antoine Pitrou92f82162008-07-25 22:22:08 +00005373- Issue #1819: function calls with several named parameters are now on
5374 average 35% faster (as measured by pybench).
5375
Amaury Forgeot d'Arce4921fe2008-07-21 22:00:38 +00005376- Issue #2378: An unexpected UnboundLocalError or NameError could appear when
5377 the python debugger steps into a class statement: the free variables (local
5378 variables defined in an outer scope) would be deleted from the outer scope.
5379
Gregory P. Smith0470bab2008-07-22 04:46:32 +00005380- Issue #2620: Overflow checking when allocating or reallocating memory
5381 was not always being done properly in some python types and extension
5382 modules. PyMem_MALLOC, PyMem_REALLOC, PyMem_NEW and PyMem_RESIZE have
5383 all been updated to perform better checks and places in the code that
5384 would previously leak memory on the error path when such an allocation
5385 failed have been fixed.

5391
Benjamin Petersone977ad42008-08-20 01:42:01 +00005392- The methods ``is_in_tuple()``, ``is_vararg()``, and ``is_keywordarg()`` of
5393 symtable.Symbol have been deprecated for removal in 3.0 and the next release.
5394
Amaury Forgeot d'Arc351ffb82008-08-18 19:23:47 +00005395- Issue #2234: distutils failed for some versions of the cygwin compiler. The
5396 version reported by these tools does not necessarily follow the python
5397 version numbering scheme, so the module is less strict when parsing it.
5398
Nick Coghlanf70385a2008-08-18 12:42:46 +00005399- Issue #2235: Added Py3k warnings for types which will become unhashable
5400 under the stricter __hash__ inheritance rules in 3.0. Several types
5401 which did not meet the rules for hash invariants and were already

Antoine Pitroude781a42008-08-09 12:43:23 +00005475 asking for a specific length. This problem only affected files opened

5518 interaction with the tp_hash slot (added in 2.6b2) are now documented
5519
Nick Coghlan2a0c2b12008-08-04 12:47:17 +00005520- Issue #643841: The language reference now provides more detailed

5527================================
5528
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00005529*Release date: 17-Jul-2008*
5530
Raymond Hettingere3ae6552008-06-20 04:18:15 +00005531Core and Builtins
5532-----------------
5533
Georg Brandl3e483f62008-07-16 22:57:41 +00005534- Issue #3156: Fix inconsistent behavior of the bytearray type: all
5535 its methods now allow for items objects that can be converted to
5536 an integer using operator.index().
5537
Mark Dickinson64b7e502008-07-16 09:40:03 +00005538- Issue #3360: Fix incorrect parsing of '020000000000.0', which
5539 produced a ValueError instead of giving the correct float.
5540
Eric Smitha5fa5a22008-07-16 00:11:49 +00005541- Issue #3083: Add alternate (#) formatting for bin, oct, hex output
5542 for str.format(). This adds the prefix 0b, 0o, or 0x, respectively.
5543
Mark Dickinson7103aa42008-07-15 19:08:33 +00005544- Issue #3008: the float type has a new instance method 'float.hex'
5545 and a new class method 'float.fromhex' to convert floating-point
5546 numbers to and from hexadecimal strings, respectively.
5547
Nick Coghlan6d6bd442008-07-15 15:40:22 +00005548- Issue #2235: __hash__ is once again inherited by default. To allow
5549 collections.Hashable to remain meaningful in the presence of the
5550 default hash implementation (object.__hash__), it is now possible
5551 to explicit block inheritance of hash by setting __hash__=None at
5552 the Python level, or tp_hash=PyObject_HashNotImplemented at the C
5553 level.
5554
Nick Coghlanb028f502008-07-13 14:52:36 +00005555- Issue #3221: Issue a RuntimeWarning instead of raising SystemError if
5556 the parent module cannot be found while performing an absolute import.
5557 This means that an incorrectly defined __package__ attribute will
5558 now only prevent relative imports in that module rather than causing
5559 all imports from that module to fail.
5560
Nick Coghlan14ff9942008-07-08 14:21:42 +00005561- Issue #2517: Allow unicode messages in Exceptions again by correctly
5562 bypassing the instance dictionary when looking up __unicode__ on
5563 new-style classes.
5564
Amaury Forgeot d'Arcbdd941f2008-07-01 20:38:04 +00005565- Issue #3242: Fix a crash inside the print statement, if sys.stdout is
5566 set to a custom object whose write() method happens to install
5567 another file in sys.stdout.
5568
Amaury Forgeot d'Arc1f40c8a2008-06-30 22:42:40 +00005569- Issue #3088: Corrected a race condition in classes derived from
5570 threading.local: the first member set by a thread could be saved in
5571 another thread's dictionary.
5572
Mark Dickinson1ec2fcd2008-06-20 14:53:43 +00005573- Issue #3004: Minor change to slice.indices(): the start and stop
5574 arguments are now treated identically, making the behaviour easier
5575 to describe and understand. For example, slice(None, -10,
5576 1).indices(9) now returns (0, 0, 1) instead of (0, -1, 1), and
5577 slice(None, 10, -1).indices(10) returns (9, 9, -1) instead of (9,
5578 10, -1).
5579
Georg Brandl278fc502008-07-19 12:46:12 +00005580- Issue #3219: Calling a function with repeated keyword arguments,
5581 f(a=2, a=23), would not cause a syntax error. This was a regression
5582 from 2.4 caused by the switch to the new compiler.
Benjamin Peterson175e4d92008-07-01 19:34:52 +00005583
Georg Brandl278fc502008-07-19 12:46:12 +00005584- Issue #2862: Make int and float freelist management consistent with
5585 other freelists. Changes their CompactFreeList apis into
5586 ClearFreeList apis and calls them via gc.collect().

5592 api functions without holding the GIL, which could lead to a fatal
5593 error when they failed.
5594
Martin v. Löwisaabf4042008-08-02 07:20:25 +00005595- Issue #799428: Fix Tkinter.Misc._nametowidget to unwrap Tcl command objects.

Amaury Forgeot d'Arc0f7cddc2008-07-06 21:34:39 +00005620- Issue #839496: SimpleHTTPServer used to open text files in text mode. This is
5621 both unnecessary (HTTP allows text content to be sent in several forms) and
Andrew M. Kuchlingcc3f2b12008-07-10 14:43:31 +00005622 wrong because the actual transmitted size could differ from the
Amaury Forgeot d'Arc0f7cddc2008-07-06 21:34:39 +00005623 content-length. The problem had been corrected in the 2.4 branch, but never
5624 merged into trunk.

Nick Coghlanc060b0e2008-07-02 13:09:19 +00005639- Issue #3190: Pydoc now hides the automatic module attribute __package__ (the

5641
Brett Cannon8bb8fa52008-07-02 01:57:08 +00005642- Issue #2885 (partial): The urllib.urlopen() function has been deprecated for

Ronald Oussoren5640ce22008-06-05 12:58:24 +00006030- On MacOS X it is now possible to install the framework in 64-bit
6031 mode or even as a 4-way universal binary (that is, PPC, i386,
Georg Brandl5cc774e2008-06-11 20:28:06 +00006032 PPC64 and x86_64 support in one binary).
Ronald Oussoren5640ce22008-06-05 12:58:24 +00006033
6034 This is controlled by the configure argument ``--with-universal-archs``:
6035
6036 - ``--with-universal-archs=all``: install 4-way universal
6037
6038 - ``--with-universal-archs=32-bit``: install 2-way universal, 32-bit (the default)
6039
6040 - ``--with-universal-archs=64-bit``: install 2-way universal, 64-bit
6041
6042 This option should be used in combination with ``--enable-universalsdk=``.
6043
6044 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 +00006094- Issue #1631171: Re-implement the 'warnings' module in C (the
6095 original Python code has been kept as backup). This will allow for
6096 using the 'warning's machinery in such places as the parser where
6097 use of pure Python code is not possible. Both the ``showarning()``
6098 and ``formatwarning()`` gain an optional 'line' argument which is
6099 not called by default for backwards-compatibility reasons. Setting
6100 ``warnings.showwarning()`` to an implementation that lacks support
6101 for the ``line`` argument will raise a DeprecationWarning.

Georg Brandl3ee81df2008-05-17 18:14:43 +00006164- Issue #2550: The approach used by client/server code for obtaining
6165 ports to listen on in network-oriented tests has been refined in an
6166 effort to facilitate running multiple instances of the entire
6167 regression test suite in parallel without issue.
6168 test_support.bind_port() has been fixed such that it will always
6169 return a unique port -- which wasn't always the case with the
6170 previous implementation, especially if socket options had been set
6171 that affected address reuse (i.e. SO_REUSEADDR, SO_REUSEPORT). The
6172 new implementation of bind_port() will actually raise an exception
6173 if it is passed an AF_INET/SOCK_STREAM socket with either the
6174 SO_REUSEADDR or SO_REUSEPORT socket option set. Furthermore, if
6175 available, bind_port() will set the SO_EXCLUSIVEADDRUSE option on
6176 the socket it's been passed. This currently only applies to
6177 Windows. This option prevents any other sockets from binding to the
6178 host/port we've bound to, thus removing the possibility of the
6179 'non-deterministic' behaviour, as Microsoft puts it, that occurs
6180 when a second SOCK_STREAM socket binds and accepts to a host/port
6181 that's already been bound by another socket. The optional preferred
6182 port parameter to bind_port() has been removed. Under no
6183 circumstances should tests be hard coding ports!
6184
6185 test_support.find_unused_port() has also been introduced, which will
6186 pass a temporary socket object to bind_port() in order to obtain an
6187 unused port. The temporary socket object is then closed and
6188 deleted, and the port is returned. This method should only be used
6189 for obtaining an unused port in order to pass to an external program
6190 (i.e. the -accept [port] argument to openssl's s_server mode) or as
6191 a parameter to a server-oriented class that doesn't give you direct
6192 access to the underlying socket used.
6193
6194 Finally, test_support.HOST has been introduced, which should be used
6195 for the host argument of any relevant socket calls (i.e. bind and
6196 connect).
Trent Nelsone41b0062008-04-08 23:47:30 +00006197
6198 The following tests were updated to following the new conventions:
Georg Brandl3ee81df2008-05-17 18:14:43 +00006199 test_socket, test_smtplib, test_asyncore, test_ssl, test_httplib,
Trent Nelsone41b0062008-04-08 23:47:30 +00006200 test_poplib, test_ftplib, test_telnetlib, test_socketserver,
6201 test_asynchat and test_socket_ssl.
6202
Georg Brandl3ee81df2008-05-17 18:14:43 +00006203 It is now possible for multiple instances of the regression test
6204 suite to run in parallel without issue.

Amaury Forgeot d'Arc9a0d3462008-03-23 09:55:29 +00006258- Issue #1477: With narrow Unicode builds, the unicode escape sequence
Georg Brandl3ee81df2008-05-17 18:14:43 +00006259 \Uxxxxxxxx did not accept values outside the Basic Multilingual
6260 Plane. This affected raw unicode literals and the
6261 'raw-unicode-escape' codec. Now UTF-16 surrogates are generated in
6262 this case, like normal unicode literals and the 'unicode-escape'
6263 codec.

Eric Smitha73fbe72008-02-23 03:09:44 +00006483- Added the future_builtins module, which contains hex() and oct().
6484 These are the PEP 3127 version of these functions, designed to be
6485 compatible with the hex() and oct() builtins from Python 3.0. They
6486 differ slightly in their output formats from the existing, unchanged
6487 Python 2.6 builtins. The expected usage of the future_builtins
6488 module is:

6490
Eric Smith7ef40bf2008-02-20 23:34:22 +00006491- Issue #1600: Modifed PyOS_ascii_formatd to use at most 2 digit
6492 exponents for exponents with absolute value < 100. Follows C99
6493 standard. This is a change on Windows, which would use 3 digits.
6494 Also, added 'n' to the formats that PyOS_ascii_formatd understands,
6495 so that any alterations it does to the resulting string will be
6496 available in stringlib/formatter.h (for float.__format__).
6497
Eric Smith5a3c1352008-02-19 13:21:56 +00006498- Implemented PEP 3101, Advanced String Formatting. This adds a new
6499 builtin format(); a format() method for str and unicode; a
6500 __format__() method to object, str, unicode, int, long, float, and
6501 datetime; the class string.Formatter; and the C API
6502 PyObject_Format().
6503
Georg Brandl3ee81df2008-05-17 18:14:43 +00006504- Fixed several potential crashes, all caused by specially crafted
6505 __del__ methods exploiting objects in temporarily inconsistent
6506 state.
Amaury Forgeot d'Arc632fad32008-02-16 20:55:24 +00006507
Vinay Sajipb7edfc42008-04-02 21:10:23 +00006508- Issue #2115: Important speedup in setting __slot__ attributes. Also
Georg Brandl3ee81df2008-05-17 18:14:43 +00006509 prevent a possible crash: an Abstract Base Class would try to access
6510 a slot on a registered virtual subclass.
Amaury Forgeot d'Arc60d6c7f2008-02-15 21:22:45 +00006511

Georg Brandl3ee81df2008-05-17 18:14:43 +00006515- Clear all free lists during a gc.collect() of the highest generation
6516 in order to allow pymalloc to free more arenas. Python may give back
6517 memory to the OS earlier.
Christian Heimes3b718a72008-02-14 12:47:33 +00006518
Georg Brandl3ee81df2008-05-17 18:14:43 +00006519- Issue #2045: Fix an infinite recursion triggered when printing a
6520 subclass of collections.defaultdict, if its default_factory is set
6521 to a bound method.

Georg Brandl3ee81df2008-05-17 18:14:43 +00006549- Patch #1473257: generator objects gain a gi_code attribute. This is
6550 the same object as the func_code attribute of the function that
6551 produced the generator.
Georg Brandl0cdf9a32008-01-26 14:14:20 +00006552
Georg Brandl3ee81df2008-05-17 18:14:43 +00006553- Issue #1920: "while 0" statements were completely removed by the
6554 compiler, even in the presence of an "else" clause, which is
6555 supposed to be run when the condition is false. Now the compiler
6556 correctly emits bytecode for the "else" suite.
Amaury Forgeot d'Arc31eaafe2008-01-24 22:59:25 +00006557
Guido van Rossumeead05f2008-01-24 18:21:02 +00006558- A few crashers fixed: weakref_in_del.py (issue #1377858);

6560 borrowed_ref_[34].py (not in tracker).
6561
Vinay Sajipd7cf32e2008-01-24 12:43:33 +00006562- Issue #1069410: The "can't load dll" message box on Windows is
Christian Heimesb2302ba2008-01-23 17:15:06 +00006563 suppressed while an extension is loaded by calling SetErrorMode in

6565
Georg Brandl3ee81df2008-05-17 18:14:43 +00006566- Issue #1915: Python compiles with --enable-unicode=no again. However
Christian Heimes082c9b02008-01-23 14:20:50 +00006567 several extension methods and modules do not work without unicode
6568 support.
6569
Georg Brandl26543b12008-01-21 18:36:51 +00006570- Issue #1882: when compiling code from a string, encoding cookies in the

6574
Georg Brandl6caad7d2008-01-26 14:19:22 +00006575- Issue #1865: ``bytes`` as an alias for ``str`` and b"" as an alias "" were
Christian Heimes288e89a2008-01-18 18:24:07 +00006576 added.
6577
Christian Heimesc94e2b52008-01-14 04:13:37 +00006578- sys.float_info / PyFloat_GetInfo: The floating point information
6579 object was converted from a dict to a specialized structseq object.
6580
Georg Brandl3ee81df2008-05-17 18:14:43 +00006581- Patch #1816: Added sys.flags structseq. It exposes the status of
6582 most command line arguments and PYTHON* environment variables.
Christian Heimesf31b69f2008-01-14 03:42:48 +00006583
Georg Brandl3ee81df2008-05-17 18:14:43 +00006584- Objects/structseq.c: Implemented new structseq representation. The
6585 patch makes structseqs (e.g. the return value of os.stat) more
6586 readable.
Christian Heimes9c201962008-01-14 03:33:52 +00006587
Georg Brandl3ee81df2008-05-17 18:14:43 +00006588- Patch #1700288: added a type attribute cache that caches method
6589 accesses, resulting in speedups in heavily object-oriented code.
Amaury Forgeot d'Arce4c270c2008-01-14 00:29:41 +00006590
Neal Norwitz3fc15b82008-01-10 05:42:58 +00006591- Bug #1776: __import__() no longer accepts filenames on any platform.

6597 envvar and sys.dont_write_bytecode attribute. All these can be set
6598 to forbid Python to attempt to write compiled bytecode files.
Georg Brandl2da0fce2008-01-07 17:09:35 +00006599
Georg Brandl3ee81df2008-05-17 18:14:43 +00006600- Improve some exception messages when Windows fails to load an
6601 extension module. Now we get for example '%1 is not a valid Win32
6602 application' instead of 'error code 193'.

6659
Georg Brandl21e99f42010-03-07 15:23:59 +00006660- The enumerate() built-in function is no longer bounded to sequences
Georg Brandl3ee81df2008-05-17 18:14:43 +00006661 smaller than LONG_MAX. Formerly, it raised an OverflowError. Now,
6662 automatically shifts from ints to longs.
Raymond Hettinger8f669372007-10-03 21:18:11 +00006663
Georg Brandl3ee81df2008-05-17 18:14:43 +00006664- Issue #1686386: Tuple's tp_repr did not take into account the
6665 possibility of having a self-referential tuple, which is possible
6666 from C code. Nor did object's tp_str consider that a type's tp_str
6667 could do something that could lead to an inifinite recursion.
6668 Py_ReprEnter() and Py_EnterRecursiveCall(), respectively, fixed the
6669 issues.
Brett Cannon0b14f242007-09-30 19:45:10 +00006670
Georg Brandl3ee81df2008-05-17 18:14:43 +00006671- Issue #1164: It was possible to trigger deadlock when using the
6672 'print' statement to write to a file since the GIL was not released
6673 as needed. Now PyObject_Print() does the right thing along with
6674 various tp_print implementations of the built-in types and those in
6675 the collections module.

Georg Brandl3ee81df2008-05-17 18:14:43 +00006685 PyObject_Call() never calling back out to Python code to trigger
6686 recursion depth updates/checks. Required the creation of a static
6687 RuntimeError instance in case normalizing an exception put the
6688 recursion check value past its limit. Fixes crashers

Georg Brandl5cb76c12007-03-21 09:00:39 +00006732- Patch #1682205: a TypeError while unpacking an iterable is no longer
6733 masked by a generic one with the message "unpack non-sequence".

Neal Norwitzaa754b72007-03-21 06:39:48 +00006735- Remove unused file Python/fmod.c.
6736
Guido van Rossum143b5642007-03-23 04:58:42 +00006737- Bug #1683368: The object.__init__() and object.__new__() methods are
6738 now stricter in rejecting excess arguments. The only time when
6739 either allows excess arguments is when it is not overridden and the
6740 other one is. For backwards compatibility, when both are
6741 overridden, it is a deprecation warning (for now; maybe a Py3k
Guido van Rossum234b1ff2007-03-23 19:39:01 +00006742 warning later). Also, type.__init__() insists on the same signature
6743 as supported by type.__new__().

Georg Brandl3ee81df2008-05-17 18:14:43 +00006745- Patch #1675423: PyComplex_AsCComplex() now tries to convert an
6746 object to complex using its __complex__() method before falling back
6747 to the __float__() method. Therefore, the functions in the cmath
6748 module now can operate on objects that define a __complex__()
6749 method.

Georg Brandl7b9c5552007-03-12 14:30:05 +00006767- Bug #1678647: write a newline after printing an exception in any
6768 case, even when converting the value to a string failed.
6769
Georg Brandl871f1bc2007-03-12 13:17:36 +00006770- The dir() function has been extended to call the __dir__() method on
Georg Brandl3ee81df2008-05-17 18:14:43 +00006771 its argument, if it exists. If not, it will work like before. This
6772 allows customizing the output of dir() in the presence of a
6773 __getattr__().

6783 raising a ValueError.
Collin Wintere38051d2007-03-09 20:33:07 +00006784
Georg Brandlaa2321b2007-03-07 00:40:28 +00006785- Patch #703779: unset __file__ in __main__ after running a file. This
Georg Brandl3ee81df2008-05-17 18:14:43 +00006786 makes the filenames the warning module prints much more sensible
6787 when a PYTHONSTARTUP file is used.

Georg Brandl0fca97a2007-03-05 22:28:08 +00006800- Patch #1674228: when assigning a slice (old-style), check for the
6801 sq_ass_slice instead of the sq_slice slot.
6802
Georg Brandl3ee81df2008-05-17 18:14:43 +00006803- When printing an unraisable error, don't print exceptions. before
6804 the name. This duplicates the behavior whening normally printing
6805 exceptions.

6814 created a weakref on itself during a __del__ call for new-style
6815 classes (classic classes still have the bug).

Georg Brandl2c1375c2006-10-12 11:27:59 +00006855- Bug #1545497: when given an explicit base, int() did ignore NULs
6856 embedded in the string to convert.
6857
Georg Brandl846f73a2006-10-08 07:11:54 +00006858- Bug #1569998: break inside a try statement (outside a loop) is now

Georg Brandl4e933132006-09-06 20:05:58 +00006888- Bug #1542051: Exceptions now correctly call PyObject_GC_UnTrack.

Neal Norwitzdac090d2006-09-05 03:53:08 +00006905- Bug #1520864: unpacking singleton tuples in list comprehensions and
Georg Brandl3ee81df2008-05-17 18:14:43 +00006906 generator expressions (x for x, in ... ) works again. Fixing this
6907 problem required changing the .pyc magic number. This means that
6908 .pyc files generated before 2.5c2 will be regenerated.

Guido van Rossum8bc09652008-02-21 18:18:37 +00006947- Removed uses of dict.has_key() from distutils, and uses of

7709 longer than 3 bytes.
Georg Brandl27562782006-10-27 20:39:43 +00007710
Georg Brandl3ee81df2008-05-17 18:14:43 +00007711- The implementation of UnicodeError objects has been simplified
7712 (start and end attributes are now stored directly as Py_ssize_t
7713 members).
Walter Dörwald84a3efe2007-06-13 16:57:12 +00007714
Georg Brandl3ee81df2008-05-17 18:14:43 +00007715- Issue #829951: In the smtplib module, SMTP.starttls() now complies
7716 with RFC 3207 and forgets any knowledge obtained from the server not
7717 obtained from the TLS negotiation itself. Patch contributed by Bill
7718 Fenner.
Gregory P. Smith2b3ba582008-01-17 08:03:17 +00007719
Georg Brandl3ee81df2008-05-17 18:14:43 +00007720- Issue #1339: The smtplib.SMTP class has been refactored a bit such
Gregory P. Smithbde4ae42008-01-17 08:35:49 +00007721 that the SMTP.starttls() caller no longer needs to call ehlo()
7722 beforehand. SMTP.starttls() now raises an exception of the server
Georg Brandl3ee81df2008-05-17 18:14:43 +00007723 does not claim to support starttls. Adds the
7724 SMTP.ehlo_or_helo_if_needed() method. Patch contributed by Bill
7725 Fenner.

Georg Brandl3ee81df2008-05-17 18:14:43 +00007767- Patch #976880: ``mmap`` objects now have an ``rfind`` method that
Andrew M. Kuchling5c60bfc2008-01-19 18:18:41 +00007768 works as expected. ``mmap.find`` also takes an optional ``end``
7769 parameter.

7794 contents before adding elements from the iterable. This fix brings
7795 the behavior into line with that for list.__init__().
Raymond Hettingeradf9ffd2007-12-13 00:08:37 +00007796
Georg Brandl3ee81df2008-05-17 18:14:43 +00007797- Added wide char functions to msvcrt module: getwch, getwche, putwch

7803
Georg Brandl3ee81df2008-05-17 18:14:43 +00007804- Marshal.dumps() now expects exact type matches for int, long, float,
7805 complex, tuple, list, dict, set, and frozenset. Formerly, it would
7806 silently miscode subclasses of those types. Now, it raises a
7807 ValueError instead.
Raymond Hettinger12e94202007-11-07 01:13:09 +00007808

Georg Brandl3ee81df2008-05-17 18:14:43 +00007823 time so that opening a database previously created with the DB_DUP
7824 or DB_DUPSORT flag set will keep the proper behavior on subsequent
7825 opens. Specifically: dictionary assignment to a DB object will
7826 replace all values for a given key when the database allows
7827 duplicate values. DB users should use DB.put(k, v) when they want
7828 to store duplicates; not DB[k] = v.
Gregory P. Smithec10a4a2007-11-05 02:32:26 +00007829

7835 characters with ASCII value less than 32. Also, it correctly quotes
7836 dots only if they occur on a single line, as opposed to the previous
7837 behavior of quoting dots if they are the second character of any
7838 line.
Georg Brandl4aef7272007-03-13 22:49:43 +00007839

7868 negative numbers, per the underlying C implementation.
Guido van Rossumbb2cc692007-01-14 17:03:32 +00007869

Georg Brandl3ee81df2008-05-17 18:14:43 +00008244- Removed the macfs module. It had been deprecated since Python 2.5.
8245 This lead to the deprecation of macostools.touched() as it relied
8246 solely on macfs and was a no-op under OS X.
