613 handles non-blocking readinto() returning None correctly.
614
Antoine Pitrouf7f390a2010-09-14 14:37:18 +0000615- Issue #9729: Fix the signature of SSLSocket.recvfrom() and
616 SSLSocket.sendto() to match the corresponding socket methods. Also,
617 fix various SSLSocket methods to raise socket.error rather than an
618 unhelpful TypeError when called on an unconnected socket. Original patch
619 by Andrew Bennetts.

Antoine Pitroue4195e82010-09-12 14:56:27 +0000626- Issue #9837: The read() method of ZipExtFile objects (as returned by
627 ZipFile.open()) could return more bytes than requested.
628
Raymond Hettinger20397532010-09-12 02:11:45 +0000629- Issue #9825: removed __del__ from the definition of collections.OrderedDict.
630 This prevents user-created self-referencing ordered dictionaries from
631 becoming permanently uncollectable GC garbage. The downside is that
632 removing __del__ means that the internal doubly-linked list has to wait for
633 GC collection rather than freeing memory immediately when the refcnt drops
634 to zero.
635

Antoine Pitrouc818ed42010-09-07 21:40:25 +0000640- Issue #9792: In case of connection failure, socket.create_connection()
641 would swallow the exception and raise a new one, making it impossible
642 to fetch the original errno, or to filter timeout errors. Now the
643 original error is re-raised.
644
Antoine Pitrouf4f61712010-09-07 16:34:47 +0000645- Issue #9758: When fcntl.ioctl() was called with mutable_flag set to True,
646 and the passed buffer was exactly 1024 bytes long, the buffer wouldn't
647 be updated back after the system call. Original patch by Brian Brazil.

666 character years even if the message contains RFC822 two character years.
667
Daniel Stutzbach91287322010-08-24 21:09:30 +0000668- Issue #8750: Fixed MutableSet's methods to correctly handle

687
Raymond Hettingera54b2da2010-08-17 19:03:06 +0000688- Issue #9626: the view methods for collections.OrderedDict() were returning

Ezio Melottiab2eb0e2010-06-05 19:21:32 +00001093- Issue #8271: during the decoding of an invalid UTF-8 byte sequence, only the

1096 E.g.: '\xf1\x80AB'.decode('utf-8', 'replace') now returns u'\ufffdAB' and
1097 replaces with U+FFFD only the start byte ('\xf1') and the continuation byte

1108 objects. (1) The comparison could incorrectly return True in some cases
1109 (2**53+1 == complex(2**53) == 2**53), breaking transivity of equality.

Georg Brandlfee0f442010-05-22 21:26:21 +00001428- On Windows, ctypes does no longer check the stack before and after calling a
1429 foreign function. This allows to use the unmodified libffi library.

Mark Dickinsond2f3e3f2010-05-05 22:23:58 +00001454 (Optimization was unintentionally turned on in gcc --with-pydebug builds in
1455 2.7 beta1 as a result of the issue #1628484 fix, combined with autoconf's

1476Core and Builtins
1477-----------------
1478
Philip Jenveyaebbaeb2010-04-06 23:24:45 +00001479- Issue #7301: Add environment variable $PYTHONWARNINGS.
1480
Benjamin Peterson3a1dfa22010-04-06 21:50:00 +00001481- Issue #8329: Don't return the same lists from select.select when no fds are
1482 changed.
1483
Georg Brandlfee0f442010-05-22 21:26:21 +00001484- Issue #8259: ``1L << (2**31)`` no longer produces an 'outrageous shift error'
Mark Dickinson82791672010-04-06 16:47:55 +00001485 on 64-bit machines. The shift count for either left or right shift is
1486 permitted to be up to sys.maxsize.
1487
Benjamin Peterson4ceeeb02010-04-03 22:48:51 +00001488- Ensure that tokenization of identifiers is not affected by locale.
1489
Georg Brandlfee0f442010-05-22 21:26:21 +00001490- Issue #1222585: Added LDCXXSHARED for C++ support. Patch by Arfrever.
Tarek Ziadé00002952010-04-03 08:37:59 +00001491
Benjamin Peterson1c7c11e2010-04-03 01:28:57 +00001492- Raise a TypeError when trying to delete a T_STRING_INPLACE struct member.
1493
Georg Brandlfee0f442010-05-22 21:26:21 +00001494- Issue #7994: Issue a PendingDeprecationWarning if object.__format__ is called
1495 with a non-empty format string. This is an effort to future-proof user
1496 code. If a derived class does not currently implement __format__ but later
1497 adds its own __format__, it would most likely break user code that had
Antoine Pitrou01a196a2011-01-02 20:05:11 +00001498 supplied a format string. This will be changed to a DeprecationWarning in
Georg Brandlfee0f442010-05-22 21:26:21 +00001499 Python 3.3 and it will be an error in Python 3.4.
Eric Smithd44b2fc2010-04-02 12:30:56 +00001500
Antoine Pitroua57df2c2010-03-31 21:32:15 +00001501- Issue #8268: Old-style classes (not just instances) now support weak

1513
Victor Stinner66644262010-03-10 22:30:19 +00001514- Issue #3137: Don't ignore errors at startup, especially a keyboard interrupt
Georg Brandlba83f822010-03-14 09:50:54 +00001515 (SIGINT). If an error occurs while importing the site module, the error is
1516 printed and Python exits. Initialize the GIL before importing the site
Victor Stinner66644262010-03-10 22:30:19 +00001517 module.

1531
Georg Brandlfee0f442010-05-22 21:26:21 +00001532- Issue #8257: The Decimal construct now accepts a float instance directly,
1533 converting that float to a Decimal of equal value:
Mark Dickinson8a950712010-04-03 15:47:46 +00001534
1535 >>> Decimal(1.1)
1536 Decimal('1.100000000000000088817841970012523233890533447265625')
1537
Raymond Hettinger34c35b22010-04-03 10:22:00 +00001538- collections.Counter() now supports a subtract() method.
1539
Georg Brandlfee0f442010-05-22 21:26:21 +00001540- The functools module now has a total_ordering() class decorator to simplify
1541 the specification of rich comparisons.
Raymond Hettingera551f312010-04-04 18:34:45 +00001542
Georg Brandlfee0f442010-05-22 21:26:21 +00001543- The functools module also adds cmp_to_key() as a tool to transition old-style
1544 comparison functions to new-style key-functions.
Raymond Hettingera551f312010-04-04 18:34:45 +00001545
Georg Brandlfee0f442010-05-22 21:26:21 +00001546- Issue #8294: The Fraction constructor now accepts Decimal and float instances
1547 directly.
Mark Dickinson7c63eee2010-04-02 22:27:36 +00001548
Georg Brandlfee0f442010-05-22 21:26:21 +00001549- Issue #7279: Comparisons involving a Decimal signaling NaN now signal
1550 InvalidOperation instead of returning False. (Comparisons involving a quiet
1551 NaN are unchanged.) Also, Decimal quiet NaNs are now hashable; Decimal
1552 signaling NaNs remain unhashable.
Mark Dickinsone096e822010-04-02 10:17:07 +00001553
Georg Brandlfee0f442010-05-22 21:26:21 +00001554- Issue #2531: Comparison operations between floats and Decimal instances now
1555 return a result based on the numeric values of the operands; previously they
1556 returned an arbitrary result based on the relative ordering of id(float) and
1557 id(Decimal).
Mark Dickinson99d80962010-04-02 08:53:22 +00001558
Barry Warsawf7f2d6f2010-03-31 21:07:16 +00001559- Issue #8233: When run as a script, py_compile.py optionally takes a single
Georg Brandlfee0f442010-05-22 21:26:21 +00001560 argument `-` which tells it to read files to compile from stdin. Each line is
1561 read on demand and the named file is compiled immediately. (Original patch by
1562 Piotr Ożarowski).
Barry Warsawf7f2d6f2010-03-31 21:07:16 +00001563
Georg Brandlfee0f442010-05-22 21:26:21 +00001564- Issue #3135: Add ``inspect.getcallargs()``, which binds arguments to a

Florent Xicluna58b65662010-03-30 16:29:03 +00001567- Backwards incompatible change: Unicode codepoints line tabulation (0x0B) and
1568 form feed (0x0C) are now considered linebreaks, as specified in Unicode
Georg Brandlfee0f442010-05-22 21:26:21 +00001569 Standard Annex #14. See issue #7643. http://www.unicode.org/reports/tr14/
Florent Xicluna22b24382010-03-30 08:24:06 +00001570
Georg Brandlfee0f442010-05-22 21:26:21 +00001571- Comparisons using one of <, <=, >, >= between a complex instance and a
1572 Fractions instance now raise TypeError instead of returning True/False. This
1573 makes Fraction <=> complex comparisons consistent with int <=> complex, float
1574 <=> complex, and complex <=> complex comparisons.
Mark Dickinson9588d992010-03-27 11:14:37 +00001575

Antoine Pitrou513d9ae2010-03-22 19:59:46 +00001585- Issue #7512: shutil.copystat() could raise an OSError when the filesystem
Georg Brandlfee0f442010-05-22 21:26:21 +00001586 didn't support chflags() (for example ZFS under FreeBSD). The error is now
1587 silenced.

1679 integer format code (one of 'bBhHiIlLqQ'), struct.pack attempts to use the

Georg Brandlfee0f442010-05-22 21:26:21 +00001681 produces a DeprecationWarning in this case. (In Python 2.6, the behaviour was
1682 inconsistent: __int__ was used for some integer codes but not for others, and
1683 the set of integer codes for which it was used differed between native packing
1684 and standard packing.)

Georg Brandlba83f822010-03-14 09:50:54 +00001896- Issue #7712: test_support gained a new ``temp_cwd`` context manager which is
1897 now also used by regrtest to run all the tests in a temporary directory. The
1898 original CWD is saved in ``test.test_support.SAVEDCWD``. Thanks to Florent
1899 Xicluna who helped with the patch.

1937 could crash in many places because of the ``PyByteArray_AS_STRING()`` macro
1938 returning NULL. The macro now returns a statically allocated empty string

Georg Brandlba83f822010-03-14 09:50:54 +00001992 file position when calling `truncate()`. It would previously change the file
1993 position to the given argument, which goes against the tradition of
Antoine Pitrouf3fa0742010-01-31 22:26:04 +00001994 ftruncate() and other truncation APIs. Patch by Pascal Chambon.
1995

1997 class used to represent files stored inside an archive. The new
1998 implementation is significantly faster and can be wrapped in a
1999 ``io.BufferedReader`` object for more speedups. It also solves an issue
2000 where interleaved calls to ``read()`` and ``readline()`` give wrong results.
2001 Patch by Nir Aides.

Benjamin Petersona43f34c2010-01-25 03:31:13 +00002010
Georg Brandlba83f822010-03-14 09:50:54 +00002011- Issue #7748: Since unicode values are supported for some metadata options in
2012 Distutils, the DistributionMetadata get_* methods will now return an utf-8
2013 encoded string for them. This ensures that the upload and register commands
2014 send the correct values to PyPI without any error.

Georg Brandlba83f822010-03-14 09:50:54 +00002285- Issue #7117: ``repr(x)`` for a float x returns a result based on the shortest
2286 decimal string that's guaranteed to round back to x under correct rounding
2287 (with round-half-to-even rounding mode). Previously it gave a string based on
2288 rounding x to 17 decimal digits. repr(x) for a complex number behaves
2289 similarly. On platforms where the correctly-rounded strtod and dtoa code is
2290 not supported (see below), repr is unchanged.
Mark Dickinsonb678de82009-11-19 18:41:49 +00002291
Georg Brandlba83f822010-03-14 09:50:54 +00002292- Issue #7117: On almost all platforms: float-to-string and string-to-float
2293 conversions within Python are now correctly rounded. Places these conversions
2294 occur include: str for floats and complex numbers; the float and complex
2295 constructors; old-style and new-style numeric formatting; serialization and
2296 deserialization of floats and complex numbers using marshal, pickle and json;
2297 parsing of float and imaginary literals in Python code; Decimal-to-float
2298 conversion.
Mark Dickinsonb678de82009-11-19 18:41:49 +00002299
Georg Brandlba83f822010-03-14 09:50:54 +00002300 The conversions use a Python-adapted version of David Gay's well-known dtoa.c,
2301 providing correctly-rounded strtod and dtoa C functions. This code is
2302 supported on Windows, and on Unix-like platforms using gcc, icc or suncc as
2303 the C compiler. There may be a small number of platforms on which correct
2304 operation of this code cannot be guaranteed, so the code is not used: notably,
2305 this applies to platforms where the C double format is not IEEE 754 binary64,
2306 and to platforms on x86 hardware where the x87 FPU is set to 64-bit precision
2307 and Python's configure script is unable to determine how to change the FPU
2308 precision. On these platforms conversions use the platform strtod and dtoa,
2309 as before.

Georg Brandlba83f822010-03-14 09:50:54 +00002311- Issue #7117: Backport round implementation from Python 3.x. ``round()`` now
2312 uses the correctly-rounded string <-> float conversions described above (when
2313 available), and so produces correctly rounded results that will display nicely
2314 under the float repr. There are two related small changes: (1) round now
2315 accepts any class with an ``__index__()`` method for its second argument (but
2316 no longer accepts floats for the second argument), and (2) an excessively
2317 large second integer argument (e.g., ``round(1.234, 10**100)``) no longer
2318 raises an exception.

Georg Brandlba83f822010-03-14 09:50:54 +00002461 (1) inf and nan strings with trailing whitespace were incorrectly rejected;
2462 (2) parsing of strings representing infinities and nans was locale aware; and
2463 (3) the interpretation of fromhex('-nan') didn't match that of float('-nan').

Georg Brandlba83f822010-03-14 09:50:54 +00002465- Issue #5920: For ``float.__format__()``, change the behavior with the empty
2466 presentation type (that is, not one of 'e', 'f', 'g', or 'n') to be like 'g'
2467 but with at least one decimal point and with a default precision
2468 of 12. Previously, the behavior the same but with a default precision of 6.
2469 This more closely matches ``str()``, and reduces surprises when adding
2470 alignment flags to the empty presentation type. This also affects the new
2471 complex.__format__ in the same way.
2472
2473- Issue #5890: In subclasses of 'property' the __doc__ attribute was shadowed by

2610
Georg Brandlba83f822010-03-14 09:50:54 +00002611- Issue #1180193: When importing a module from a .pyc (or .pyo) file with an
2612 existing .py counterpart, override the co_filename attributes of all code
2613 objects if the original filename is obsolete (which can happen if the file has
2614 been renamed, moved, or if it is accessed through different paths). Patch by
2615 Ziga Seilnacht and Jean-Paul Calderone.

Georg Brandl6425a2f2008-12-28 11:54:53 +00002634- Issue #4759: None is now allowed as the first argument of
Georg Brandlba83f822010-03-14 09:50:54 +00002635 ``bytearray.translate()``. It was always allowed for ``bytes.translate()``.

Georg Brandlba83f822010-03-14 09:50:54 +00002654- Issue #4445: Replace ``sizeof(PyStringObject)`` with
2655 ``offsetof(PyStringObject, ob_sval) + 1`` when allocating memory for str
2656 instances. On a typical machine this saves 3 bytes of memory (on average) per
2657 string allocation.

Amaury Forgeot d'Arcdc619012008-11-22 20:01:18 +00002659- Issue #3996: On Windows, the PyOS_CheckStack function would cause the

2661 instead of throwing a MemoryError.
2662
Georg Brandlba83f822010-03-14 09:50:54 +00002663- Issue #3689: The list reversed iterator now supports __length_hint__ instead

Benjamin Petersonc078f922008-11-21 22:27:24 +00002666- Issue #4367: Python would segfault during compiling when the unicodedata

2668
Georg Brandlba83f822010-03-14 09:50:54 +00002669- Issue #4233: Changed semantic of ``_fileio.FileIO``'s ``close()`` method on
2670 file objects with closefd=False. The file descriptor is still kept open but
2671 the file object behaves like a closed file. The ``FileIO`` object also got a
2672 new readonly attribute ``closefd``.

Benjamin Peterson46cc6d12008-11-19 21:49:09 +00002674- Issue #4348: Some bytearray methods returned that didn't cause any change to
2675 the bytearray, returned the same bytearray instead of a copy.
2676

Benjamin Petersonbdca9422008-10-26 20:21:13 +00002689- Issue #4209: Enabling unicode_literals and the print_function in the same
2690 __future__ import didn't work.
2691
Benjamin Peterson399b1fe2008-10-25 02:53:28 +00002692- Using ``nonlocal`` as a variable name will now raise a Py3k SyntaxWarning
Georg Brandl7fb00ad2008-10-25 07:00:52 +00002693 because it is a reserved word in 3.x.

Georg Brandlba83f822010-03-14 09:50:54 +00002695- On windows, ``os.chdir()`` given unicode was not working if
2696 GetCurrentDirectoryW returned a path longer than MAX_PATH. (But It's doubtful
2697 this code path is really executed because I cannot move to such directory on
2698 win2k)

Georg Brandlba83f822010-03-14 09:50:54 +00002700- Issue #4069: When ``set.remove(element)`` is used with a set element, the
2701 element is temporarily replaced with an equivalent frozenset. But the
2702 eventual KeyError would always report the empty ``frozenset()`` as the missing
2703 key. Now it correctly refers to the initial element.

2722
Walter Dörwalded960ac2009-05-03 22:36:33 +00002723- Issue #5108: Handle %s like %S and %R in PyUnicode_FromFormatV(): Call
2724 PyUnicode_DecodeUTF8() once, remember the result and output it in a second
2725 step. This avoids problems with counting UTF-8 bytes that ignores the effect
2726 of using the replace error handler in PyUnicode_DecodeUTF8().
2727
Walter Dörwald726ba8e2009-05-06 14:32:35 +00002728- Issue #3739: The unicode-internal encoder now reports the number of characters
2729 consumed like any other encoder (instead of the number of bytes).
2730
Georg Brandlba83f822010-03-14 09:50:54 +00002731- Issue #2422: When compiled with the ``--with-valgrind`` option, the pymalloc
2732 allocator will be automatically disabled when running under Valgrind. This
2733 gives improved memory leak detection when running under Valgrind, while taking
2734 advantage of pymalloc at other times.

3965 __all__ attribute, rather than using a hardcoded and incomplete list.
3966
R. David Murray14dcd432009-10-14 13:58:07 +00003967- Issue #7058: Added save/restore for things like sys.argv and cwd to
3968 runtest_inner in regrtest, with warnings if the called test modifies them,
3969 and a new section in the summary report at the end.

Brett Cannone7e941e2009-09-03 21:25:21 +00003973- Issue #6806: test_platform failed under OS X 10.6.0 because ``sw_ver`` leaves
3974 off the trailing 0 in the version number.
3975
Guilherme Polo7f146ab2009-06-21 17:22:50 +00003976- Issue #5450: Moved tests involving loading tk from Lib/test/test_tcl to
3977 Lib/lib-tk/test/test_tkinter/test_loadtk. With this, these tests demonstrate
Georg Brandlba83f822010-03-14 09:50:54 +00003978 the same behaviour as test_ttkguionly (and now also test_tk) which is to skip
3979 the tests if DISPLAY is defined but can't be used.

Antoine Pitrou4698d992009-05-31 14:20:14 +00003981- Issue #6152: New option '-j'/'--multiprocess' for regrtest allows running
3982 regression tests in parallel, shortening the total runtime.
3983
Georg Brandlba83f822010-03-14 09:50:54 +00003984- Issue #5354: New test support function import_fresh_module() makes it easy to
3985 import both normal and optimised versions of modules. test_heapq and
3986 test_warnings have been adjusted to use it, tests for other modules with both
3987 C and Python implementations in the stdlib can be adjusted to use it over
3988 time.

3995
Georg Brandlba83f822010-03-14 09:50:54 +00003996- regrtest no longer treats ImportError as equivalent to SkipTest. Imports that
3997 should cause a test to be skipped are now done using import_module from test
3998 support, which does the conversion.

4100
Amaury Forgeot d'Arc05e34492008-09-10 22:04:45 +00004101- Issue #3743: In a few places, PY_FORMAT_SIZE_T was incorrectly used with
4102 PyString_FromFormat or PyErr_Format to display size_t values. The macro
4103 PY_FORMAT_SIZE_T is designed to select the correct format for the OS
4104 ``printf`` function, whereas PyString_FromFormat has an independent
4105 implementation and uses "%zd" on all platforms for size_t values.
4106 This makes a difference on win64, where ``printf`` needs "%Id" to display
4107 64bit values.
4108
Benjamin Peterson97179b02008-09-09 20:55:01 +00004109- Issue #3634: _weakref.ref(Exception).__init__() gave invalid return value on

4113 object; previously an int would be returned for small values. the __long__
4114 method is allowed to return either an int or a long, but the behaviour of
4115 float objects should not change to respect backward compatibility.
4116
Amaury Forgeot d'Arc3571fbf2008-09-01 19:52:00 +00004117- Issue #3751: str.rpartition would perform a left-partition when called with

Vinay Sajip35e3b032008-09-01 14:33:59 +00004123 PyArg_ParseTuple and friends, which occurred when the argument for "s*"
Antoine Pitroud4ae97b2008-08-29 18:39:48 +00004124 was correctly parsed but parsing of subsequent arguments failed.
4125
Vinay Sajip35e3b032008-09-01 14:33:59 +00004126- Issue #2534: speed up isinstance() and issubclass() by 50-70%, so as to
Antoine Pitrou0668c622008-08-26 22:42:08 +00004127 match Python 2.5 speed despite the __instancecheck__ / __subclasscheck__
4128 mechanism. In the process, fix a bug where isinstance() and issubclass(),
4129 when given a tuple of classes as second argument, were looking up
4130 __instancecheck__ / __subclasscheck__ on the tuple rather than on each
4131 type object.
4132
Neal Norwitz18aa3882008-08-24 05:04:52 +00004133- Fix crashes on memory allocation failure found with failmalloc.

Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00004270What's New in Python 2.6 beta 3?
4271================================
4272
Barry Warsaw07a4a382008-08-21 01:15:08 +00004273*Release date: 20-Aug-2008*
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00004274
4275Core and Builtins
4276-----------------
4277
Guido van Rossumf8402962008-08-20 15:01:50 +00004278- Issue #1878: Remove Py_TPFLAGS_HAVE_VERSION_TAG from
4279 Py_TPFLAGS_DEFAULT when not building the core. This means 3rd party
4280 extensions do not automatically benefit from the class attribute
4281 cache; they will have to explicitly add Py_TPFLAGS_HAVE_VERSION_TAG
4282 to their tp_flags field if they care. This is a backwards
4283 compatibility feature; in 3.0, all types will use the cache by
4284 default.
4285
Benjamin Petersonf647dc12008-08-20 01:27:30 +00004286- Keyword arguments can now follow starred arguments. (``f(a, *args,
4287 keyword=23)`` is now valid syntax.)
4288
Thomas Heller0ad5ae02008-08-19 19:25:04 +00004289- ctypes function pointers that are COM methods have a boolean True
4290 value again.
4291
Martin v. Löwisf91d46a2008-08-12 14:49:50 +00004292- Issue #3139: Make buffer-interface thread-safe wrt. PyArg_ParseTuple,
4293 by denying s# to parse objects that have a releasebuffer procedure,
4294 and introducing s*.
4295
Georg Brandl1e13ea92008-08-11 09:07:59 +00004296- Issue #3537: Fix an assertion failure when an empty but presized dict
4297 object was stored in the freelist.
4298
Mark Dickinsonb6467572008-08-04 21:30:09 +00004299- Issue #1481296: Make long(float('nan')) and int(float('nan')) raise
4300 ValueError consistently across platforms.
4301
Amaury Forgeot d'Arc39fd6722008-07-31 21:28:03 +00004302- Issue #3479: On platforms where sizeof(int) is smaller than sizeof(long)
4303 (64bit Unix, for example), unichr() would truncate its argument and return
4304 u'\x00' for unichr(2**32). Now it properly raises an OverflowError.
4305
Neal Norwitze7d8be82008-07-31 17:17:14 +00004306- Apply security patches from Apple.
4307
Amaury Forgeot d'Arc246daed2008-07-31 00:42:16 +00004308- Issue #2542: Now that issubclass() may call arbitrary code, ensure that
4309 PyErr_ExceptionMatches returns 0 when an exception occurs there.
4310
Antoine Pitrou92f82162008-07-25 22:22:08 +00004311- Issue #1819: function calls with several named parameters are now on
4312 average 35% faster (as measured by pybench).
4313
Amaury Forgeot d'Arce4921fe2008-07-21 22:00:38 +00004314- Issue #2378: An unexpected UnboundLocalError or NameError could appear when
4315 the python debugger steps into a class statement: the free variables (local
4316 variables defined in an outer scope) would be deleted from the outer scope.
4317
Gregory P. Smith0470bab2008-07-22 04:46:32 +00004318- Issue #2620: Overflow checking when allocating or reallocating memory
4319 was not always being done properly in some python types and extension
4320 modules. PyMem_MALLOC, PyMem_REALLOC, PyMem_NEW and PyMem_RESIZE have
4321 all been updated to perform better checks and places in the code that
4322 would previously leak memory on the error path when such an allocation
4323 failed have been fixed.

4326-------
4327
Hirokazu Yamamoto838c79f2008-08-20 13:14:07 +00004328- Issue #3612: Added some missing basic types in ctypes.wintypes.
4329
Benjamin Petersone977ad42008-08-20 01:42:01 +00004330- The methods ``is_in_tuple()``, ``is_vararg()``, and ``is_keywordarg()`` of
4331 symtable.Symbol have been deprecated for removal in 3.0 and the next release.
4332
Amaury Forgeot d'Arc351ffb82008-08-18 19:23:47 +00004333- Issue #2234: distutils failed for some versions of the cygwin compiler. The
4334 version reported by these tools does not necessarily follow the python
4335 version numbering scheme, so the module is less strict when parsing it.
4336
Nick Coghlanf70385a2008-08-18 12:42:46 +00004337- Issue #2235: Added Py3k warnings for types which will become unhashable
4338 under the stricter __hash__ inheritance rules in 3.0. Several types
4339 which did not meet the rules for hash invariants and were already
4340 unhashable in 3.0 have now been explicitly flagged as unhashable in
4341 2.6 as well (collections.Mapping, collections.Set, unittest.TestSuite,
4342 xml.dom.minidom.NamedNodeMap, numbers.Number, UserList.UserList)
4343
Brett Cannon88f801d2008-08-18 00:46:22 +00004344- Update __all__ for cookielib, csv, os, urllib2, and weakref to include things
4345 imported into the module but exposed as part of the module's API.
4346
Brett Cannon7b96f072008-08-18 00:41:11 +00004347- Remove an unneeded import of abc.ABCMeta from 'inspect'.
4348
Brett Cannon46225e72008-08-18 00:36:52 +00004349- Remove unneeded imports of 'sys' and 'warnings' from 'io'.
4350
Brett Cannon25c9d6a2008-08-17 22:10:11 +00004351- Remove unneeded imports of 'warnings' from shelve, filecmp, and dummy_thread.
4352
Hirokazu Yamamoto41a81eb2008-08-17 13:10:46 +00004353- Issue #3575: Incremental decoder's decode function now takes bytearray
4354 by using 's*' instead of 't#'.
4355
Mark Dickinson3e4caeb2009-02-21 20:27:01 +00004356- Issue #2222: Fixed reference leak when occurred os.rename()
Hirokazu Yamamoto7f30a682008-08-17 09:46:56 +00004357 fails unicode conversion on 2nd parameter. (windows only)
4358
Georg Brandl222e2082010-08-01 22:27:39 +00004359- Issue #2464: urllib2 now supports a malformation in the URL received
Facundo Batista94f243a2008-08-17 03:38:39 +00004360 in a redirect.
4361
Brett Cannonabe423e2008-08-16 21:47:07 +00004362- Silence the DeprecationWarning raised when importing mimetools in
Brett Cannon721b1452008-08-16 22:00:27 +00004363 BaseHTTPServer, cgi (and rfc822), httplib.
Brett Cannonabe423e2008-08-16 21:47:07 +00004364
Facundo Batistaeb90b782008-08-16 14:44:07 +00004365- Issue #2776: fixed small issue when handling an URL with double slash
4366 after a 302 response in the case of not going through a proxy.
4367
Antoine Pitroub90a8be2008-08-15 21:03:21 +00004368- Issue #2676: in the email package, content-type parsing was hanging on
4369 pathological input because of quadratic or exponential behaviour of a
4370 regular expression.
4371
Antoine Pitrou11ec65d2008-08-14 21:04:30 +00004372- Issue #3476: binary buffered reading through the new "io" library is now
4373 thread-safe.
4374
Brett Cannonbf3157b2008-08-14 05:00:03 +00004375- Silence the DeprecationWarning of rfc822 when it is imported by mimetools
4376 since mimetools itself is deprecated. Because modules are cached, all
4377 subsequent imports of rfc822 will not raise a visible DeprecationWarning.
4378
Antoine Pitrou9fcd4b32008-08-11 17:21:36 +00004379- Issue #3134: shutil referenced undefined WindowsError symbol.
4380
Robert Schuppenies14646332008-08-10 11:01:53 +00004381- Issue #1342811: Fix leak in Tkinter.Menu.delete. Commands associated to
4382 menu entries were not deleted.
4383
Brett Cannon83e81842008-08-09 23:30:55 +00004384- Copied the implementation of reduce() to _functools.reduce() to have a
4385 version that did not raise a DeprecationWarning under -3.
4386
Antoine Pitrou76b8bee2008-08-09 17:27:23 +00004387- Issue #3205: When iterating over a BZ2File fails allocating memory, raise
4388 a MemoryError rather than silently stop the iteration.
4389
Guido van Rossum59ce9012008-08-09 14:55:34 +00004390- Issue #3487: sre "bytecode" validator. Passing invalid "re-bytecode"
4391 to _sre.compile() will now be rejected. This should not affect anybody
4392 since the re.compile() function never generates invalid re-bytecode.
4393
Skip Montanaroa032bf42008-08-08 22:52:51 +00004394- Issue #3436: Make csv.DictReader's fieldnames attribute a property so that
4395 upon first access it can be automatically initialized from the csv file if
4396 it wasn't initialized during instantiation.
4397
Brett Cannon3aa2a492008-08-06 22:28:09 +00004398- Issue #2338: Create imp.reload() to help with transitioning to Python 3.0 as
4399 the reload() built-in has been removed.
4400
Brett Cannon7e30b672008-08-04 21:52:25 +00004401- Changed code in the following modules/packages to remove warnings raised
Brett Cannonc1b76e42008-08-09 23:06:16 +00004402 while running under the ``-3`` flag: aifc, asynchat, asyncore, bdb, bsddb,

4405 pstats, pydoc, re, rlcompleter, SimpleXMLRPCServer, shelve, socket,
4406 subprocess, sqlite3, tarfile, Tkinter, test.test_support, textwrap,
4407 threading, tokenize, traceback, urlparse, wsgiref, xml, xmlrpclib.
Brett Cannon7e30b672008-08-04 21:52:25 +00004408
Lars Gustäbel727bd0b2008-08-02 11:26:39 +00004409- Issue #3039: Fix tarfile.TarFileCompat.writestr() which always
4410 raised an AttributeError.
4411
Benjamin Peterson01a24322008-07-28 23:35:27 +00004412- Issue #2523: Fix quadratic behaviour when read()ing a binary file without
Antoine Pitroude781a42008-08-09 12:43:23 +00004413 asking for a specific length. This problem only affected files opened
4414 using the new "io" module, not the built-in open() function.
Benjamin Peterson01a24322008-07-28 23:35:27 +00004415
Mark Dickinsonfe84cce2008-07-27 06:39:07 +00004416- Issue #3449: Update decimal module to use most recent specification
4417 (v. 1.68) and tests (v. 2.58) from IBM.
4418
Georg Brandl222e2082010-08-01 22:27:39 +00004419- Issue #3437: Bug fix in robotparser parsing of Allow: lines.
Skip Montanarof9ac43f2008-07-27 00:50:41 +00004420

4423
Georg Brandlf9efabb2008-07-23 15:16:45 +00004424- Deprecate the "ast" parser function aliases.
4425
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00004426- Issue #3120: On 64-bit Windows the subprocess module was truncating handles.
4427
4428- Issue #3303: Fix a crash in locale.strcoll() when calling it with
4429 invalid arguments.
4430
4431- Issue #3302: Fix several crashes when calling locale's gettext functions
4432 with None arguments.
4433
4434- Issue #3389: Allow resolving dotted names for handlers in logging
4435 configuration files.
4436
4437- Deprecate the sunaudio module for removal in Python 3.0.
4438
Antoine Pitrou5fdfa3e2008-07-25 19:42:26 +00004439- Issue #3394: zipfile.writestr sets external attributes when passed a
4440 file name rather than a ZipInfo instance, so files are extracted with
4441 mode 0600 rather than 000 under Unix.
4442
Gregory P. Smitha36f8fe2008-08-04 00:13:29 +00004443- Issue #1857: subprocess.Popen.poll gained an additional _deadstate keyword
4444 argument in python 2.5, this broke code that subclassed Popen to include its
4445 own poll method. Fixed my moving _deadstate to an _internal_poll method.

4454
Nick Coghlan6e8fef02008-08-18 13:14:22 +00004455- Issue #2235: the C API function PyObject_HashNotImplemented and its
4456 interaction with the tp_hash slot (added in 2.6b2) are now documented
4457
Nick Coghlan2a0c2b12008-08-04 12:47:17 +00004458- Issue #643841: The language reference now provides more detailed
4459 coverage of the lookup process for special methods. The disclaimers
4460 regarding lack of coverage of new-style classes have also been
4461 removed, since the coverage is now fairly reasonable.

4470-----------------
4471
Georg Brandl3e483f62008-07-16 22:57:41 +00004472- Issue #3156: Fix inconsistent behavior of the bytearray type: all
4473 its methods now allow for items objects that can be converted to
4474 an integer using operator.index().
4475
Mark Dickinson64b7e502008-07-16 09:40:03 +00004476- Issue #3360: Fix incorrect parsing of '020000000000.0', which
4477 produced a ValueError instead of giving the correct float.
4478
Eric Smitha5fa5a22008-07-16 00:11:49 +00004479- Issue #3083: Add alternate (#) formatting for bin, oct, hex output
4480 for str.format(). This adds the prefix 0b, 0o, or 0x, respectively.
4481
Mark Dickinson7103aa42008-07-15 19:08:33 +00004482- Issue #3008: the float type has a new instance method 'float.hex'
4483 and a new class method 'float.fromhex' to convert floating-point
4484 numbers to and from hexadecimal strings, respectively.
4485
Nick Coghlan6d6bd442008-07-15 15:40:22 +00004486- Issue #2235: __hash__ is once again inherited by default. To allow
4487 collections.Hashable to remain meaningful in the presence of the
4488 default hash implementation (object.__hash__), it is now possible
4489 to explicit block inheritance of hash by setting __hash__=None at
4490 the Python level, or tp_hash=PyObject_HashNotImplemented at the C
4491 level.
4492
Nick Coghlanb028f502008-07-13 14:52:36 +00004493- Issue #3221: Issue a RuntimeWarning instead of raising SystemError if
4494 the parent module cannot be found while performing an absolute import.
4495 This means that an incorrectly defined __package__ attribute will
4496 now only prevent relative imports in that module rather than causing
4497 all imports from that module to fail.
4498
Nick Coghlan14ff9942008-07-08 14:21:42 +00004499- Issue #2517: Allow unicode messages in Exceptions again by correctly
4500 bypassing the instance dictionary when looking up __unicode__ on
4501 new-style classes.
4502
Amaury Forgeot d'Arcbdd941f2008-07-01 20:38:04 +00004503- Issue #3242: Fix a crash inside the print statement, if sys.stdout is
4504 set to a custom object whose write() method happens to install
4505 another file in sys.stdout.

4509 another thread's dictionary.
4510
Mark Dickinson1ec2fcd2008-06-20 14:53:43 +00004511- Issue #3004: Minor change to slice.indices(): the start and stop
4512 arguments are now treated identically, making the behaviour easier
4513 to describe and understand. For example, slice(None, -10,
4514 1).indices(9) now returns (0, 0, 1) instead of (0, -1, 1), and
4515 slice(None, 10, -1).indices(10) returns (9, 9, -1) instead of (9,
4516 10, -1).
4517
Georg Brandl278fc502008-07-19 12:46:12 +00004518- Issue #3219: Calling a function with repeated keyword arguments,
4519 f(a=2, a=23), would not cause a syntax error. This was a regression
4520 from 2.4 caused by the switch to the new compiler.

Georg Brandl5cc774e2008-06-11 20:28:06 +00004970 PPC64 and x86_64 support in one binary).
Ronald Oussoren5640ce22008-06-05 12:58:24 +00004971
4972 This is controlled by the configure argument ``--with-universal-archs``:
4973
4974 - ``--with-universal-archs=all``: install 4-way universal
4975
4976 - ``--with-universal-archs=32-bit``: install 2-way universal, 32-bit (the default)
4977
4978 - ``--with-universal-archs=64-bit``: install 2-way universal, 64-bit
4979
4980 This option should be used in combination with ``--enable-universalsdk=``.

5019 two handlers that derive the same default base class.
Amaury Forgeot d'Arc96865852008-04-22 21:14:41 +00005020
Christian Heimese74c8f22008-04-19 02:23:57 +00005021- Added kill, terminate and send_signal(sig) to subprocess.Popen.

Georg Brandl3ee81df2008-05-17 18:14:43 +00005032- Issue #1631171: Re-implement the 'warnings' module in C (the
5033 original Python code has been kept as backup). This will allow for
5034 using the 'warning's machinery in such places as the parser where
5035 use of pure Python code is not possible. Both the ``showarning()``
5036 and ``formatwarning()`` gain an optional 'line' argument which is
5037 not called by default for backwards-compatibility reasons. Setting
5038 ``warnings.showwarning()`` to an implementation that lacks support
5039 for the ``line`` argument will raise a DeprecationWarning.

5063
Gregory P. Smithd59fefb2008-04-22 08:11:33 +00005064- The getpass module has been improved on Unix. It now uses /dev/tty
5065 by default and uses stderr instead of stdout. A GetPassWarning is
5066 issued when input echo cannot be controlled.

Georg Brandl3ee81df2008-05-17 18:14:43 +00005081- Issue #2513: distutils on Windows is now capable of cross-compiling
Mark Hammond495cf992008-04-07 01:53:39 +00005082 extension modules between 32 and 64 bit platforms. See the distutls

Georg Brandl3ee81df2008-05-17 18:14:43 +00005094- Issue #2385: distutils.core.run_script() makes __file__ available,
5095 so the controlled environment will more closely mirror the typical
5096 script environment. This supports setup.py scripts that refer to
5097 data files.

Georg Brandl3ee81df2008-05-17 18:14:43 +00005102- Issue #2550: The approach used by client/server code for obtaining
5103 ports to listen on in network-oriented tests has been refined in an
5104 effort to facilitate running multiple instances of the entire
5105 regression test suite in parallel without issue.
5106 test_support.bind_port() has been fixed such that it will always
5107 return a unique port -- which wasn't always the case with the
5108 previous implementation, especially if socket options had been set
5109 that affected address reuse (i.e. SO_REUSEADDR, SO_REUSEPORT). The
5110 new implementation of bind_port() will actually raise an exception
5111 if it is passed an AF_INET/SOCK_STREAM socket with either the
5112 SO_REUSEADDR or SO_REUSEPORT socket option set. Furthermore, if
5113 available, bind_port() will set the SO_EXCLUSIVEADDRUSE option on
5114 the socket it's been passed. This currently only applies to
5115 Windows. This option prevents any other sockets from binding to the
5116 host/port we've bound to, thus removing the possibility of the
5117 'non-deterministic' behaviour, as Microsoft puts it, that occurs
5118 when a second SOCK_STREAM socket binds and accepts to a host/port
5119 that's already been bound by another socket. The optional preferred
5120 port parameter to bind_port() has been removed. Under no
5121 circumstances should tests be hard coding ports!
5122
5123 test_support.find_unused_port() has also been introduced, which will
5124 pass a temporary socket object to bind_port() in order to obtain an
5125 unused port. The temporary socket object is then closed and
5126 deleted, and the port is returned. This method should only be used
5127 for obtaining an unused port in order to pass to an external program
5128 (i.e. the -accept [port] argument to openssl's s_server mode) or as
5129 a parameter to a server-oriented class that doesn't give you direct
5130 access to the underlying socket used.
5131
5132 Finally, test_support.HOST has been introduced, which should be used
5133 for the host argument of any relevant socket calls (i.e. bind and
5134 connect).
Trent Nelsone41b0062008-04-08 23:47:30 +00005135
5136 The following tests were updated to following the new conventions:
Georg Brandl3ee81df2008-05-17 18:14:43 +00005137 test_socket, test_smtplib, test_asyncore, test_ssl, test_httplib,
Trent Nelsone41b0062008-04-08 23:47:30 +00005138 test_poplib, test_ftplib, test_telnetlib, test_socketserver,
5139 test_asynchat and test_socket_ssl.
5140
Georg Brandl3ee81df2008-05-17 18:14:43 +00005141 It is now possible for multiple instances of the regression test
5142 suite to run in parallel without issue.

Eric Smitha73fbe72008-02-23 03:09:44 +00005421- Added the future_builtins module, which contains hex() and oct().
5422 These are the PEP 3127 version of these functions, designed to be
5423 compatible with the hex() and oct() builtins from Python 3.0. They
5424 differ slightly in their output formats from the existing, unchanged
5425 Python 2.6 builtins. The expected usage of the future_builtins
5426 module is:
5427 from future_builtins import hex, oct
5428
Eric Smith7ef40bf2008-02-20 23:34:22 +00005429- Issue #1600: Modifed PyOS_ascii_formatd to use at most 2 digit
5430 exponents for exponents with absolute value < 100. Follows C99
5431 standard. This is a change on Windows, which would use 3 digits.
5432 Also, added 'n' to the formats that PyOS_ascii_formatd understands,
5433 so that any alterations it does to the resulting string will be
5434 available in stringlib/formatter.h (for float.__format__).
5435
Eric Smith5a3c1352008-02-19 13:21:56 +00005436- Implemented PEP 3101, Advanced String Formatting. This adds a new
5437 builtin format(); a format() method for str and unicode; a
5438 __format__() method to object, str, unicode, int, long, float, and
5439 datetime; the class string.Formatter; and the C API
5440 PyObject_Format().
5441
Georg Brandl3ee81df2008-05-17 18:14:43 +00005442- Fixed several potential crashes, all caused by specially crafted
5443 __del__ methods exploiting objects in temporarily inconsistent
5444 state.
Amaury Forgeot d'Arc632fad32008-02-16 20:55:24 +00005445
Vinay Sajipb7edfc42008-04-02 21:10:23 +00005446- Issue #2115: Important speedup in setting __slot__ attributes. Also
Georg Brandl3ee81df2008-05-17 18:14:43 +00005447 prevent a possible crash: an Abstract Base Class would try to access
5448 a slot on a registered virtual subclass.
Amaury Forgeot d'Arc60d6c7f2008-02-15 21:22:45 +00005449
Georg Brandl3ee81df2008-05-17 18:14:43 +00005450- Fixed repr() and str() of complex numbers with infinity or nan as
5451 real or imaginary part.

Georg Brandl3ee81df2008-05-17 18:14:43 +00005453- Clear all free lists during a gc.collect() of the highest generation
5454 in order to allow pymalloc to free more arenas. Python may give back
5455 memory to the OS earlier.
Christian Heimes3b718a72008-02-14 12:47:33 +00005456
Georg Brandl3ee81df2008-05-17 18:14:43 +00005457- Issue #2045: Fix an infinite recursion triggered when printing a
5458 subclass of collections.defaultdict, if its default_factory is set
5459 to a bound method.
Amaury Forgeot d'Arcb01aa432008-02-08 00:56:02 +00005460
Christian Heimesf75dbef2008-02-08 00:11:31 +00005461- Fixed a minor memory leak in dictobject.c. The content of the free
5462 list was not freed on interpreter shutdown.
5463
Georg Brandl21e99f42010-03-07 15:23:59 +00005464- Limit free list of method and built-in function objects to 256
Georg Brandl3ee81df2008-05-17 18:14:43 +00005465 entries each.
Christian Heimes6075a822008-02-06 12:44:34 +00005466
Georg Brandl3ee81df2008-05-17 18:14:43 +00005467- Patch #1953: Added ``sys._compact_freelists()`` and the C API
5468 functions ``PyInt_CompactFreeList`` and ``PyFloat_CompactFreeList``
Christian Heimes422051a2008-02-04 18:00:12 +00005469 to compact the internal free lists of pre-allocted ints and floats.
5470
Georg Brandl3ee81df2008-05-17 18:14:43 +00005471- Issue #1983: Fixed return type of fork(), fork1() and forkpty()
5472 calls. Python expected the return type int but the fork familie
5473 returns pi_t.
Christian Heimes951cc0f2008-01-31 23:08:23 +00005474
Georg Brandl3ee81df2008-05-17 18:14:43 +00005475- Issue #1678380: Fix a bug that identifies 0j and -0j when they
5476 appear in the same code unit.

Georg Brandl3ee81df2008-05-17 18:14:43 +00005487- Patch #1473257: generator objects gain a gi_code attribute. This is
5488 the same object as the func_code attribute of the function that
5489 produced the generator.
Georg Brandl0cdf9a32008-01-26 14:14:20 +00005490
Georg Brandl3ee81df2008-05-17 18:14:43 +00005491- Issue #1920: "while 0" statements were completely removed by the
5492 compiler, even in the presence of an "else" clause, which is
5493 supposed to be run when the condition is false. Now the compiler
5494 correctly emits bytecode for the "else" suite.
Amaury Forgeot d'Arc31eaafe2008-01-24 22:59:25 +00005495
Guido van Rossumeead05f2008-01-24 18:21:02 +00005496- A few crashers fixed: weakref_in_del.py (issue #1377858);
5497 loosing_dict_ref.py (issue #1303614, test67.py);
5498 borrowed_ref_[34].py (not in tracker).
5499
Vinay Sajipd7cf32e2008-01-24 12:43:33 +00005500- Issue #1069410: The "can't load dll" message box on Windows is
Christian Heimesb2302ba2008-01-23 17:15:06 +00005501 suppressed while an extension is loaded by calling SetErrorMode in
5502 dynload_win.c. The error is still reported properly.
5503
Georg Brandl3ee81df2008-05-17 18:14:43 +00005504- Issue #1915: Python compiles with --enable-unicode=no again. However
Christian Heimes082c9b02008-01-23 14:20:50 +00005505 several extension methods and modules do not work without unicode
5506 support.
5507
Georg Brandl26543b12008-01-21 18:36:51 +00005508- Issue #1882: when compiling code from a string, encoding cookies in the
5509 second line of code were not always recognized correctly.
5510
Georg Brandl14404b62008-01-19 19:27:05 +00005511- Issue #1679: "0x" was taken as a valid integer literal.
5512
Georg Brandl6caad7d2008-01-26 14:19:22 +00005513- Issue #1865: ``bytes`` as an alias for ``str`` and b"" as an alias "" were
Christian Heimes288e89a2008-01-18 18:24:07 +00005514 added.
5515
Christian Heimesc94e2b52008-01-14 04:13:37 +00005516- sys.float_info / PyFloat_GetInfo: The floating point information
5517 object was converted from a dict to a specialized structseq object.
5518
Georg Brandl3ee81df2008-05-17 18:14:43 +00005519- Patch #1816: Added sys.flags structseq. It exposes the status of
5520 most command line arguments and PYTHON* environment variables.
Christian Heimesf31b69f2008-01-14 03:42:48 +00005521
Georg Brandl3ee81df2008-05-17 18:14:43 +00005522- Objects/structseq.c: Implemented new structseq representation. The
5523 patch makes structseqs (e.g. the return value of os.stat) more
5524 readable.
Christian Heimes9c201962008-01-14 03:33:52 +00005525
Georg Brandl3ee81df2008-05-17 18:14:43 +00005526- Patch #1700288: added a type attribute cache that caches method

Georg Brandl3ee81df2008-05-17 18:14:43 +00005548 and INF. float("nan"), float("inf") and float("-inf") now work on
5549 every platform with IEEE 754 semantics.
Christian Heimes0a8143f2007-12-18 23:22:54 +00005550
Georg Brandl3ee81df2008-05-17 18:14:43 +00005551- Compiler now generates simpler and faster code for dictionary
5552 literals. The oparg for BUILD_MAP now indicates an estimated
5553 dictionary size. There is a new opcode, STORE_MAP, for adding
5554 entries to the dictionary.

Georg Brandl21e99f42010-03-07 15:23:59 +00005598- The enumerate() built-in function is no longer bounded to sequences
Georg Brandl3ee81df2008-05-17 18:14:43 +00005599 smaller than LONG_MAX. Formerly, it raised an OverflowError. Now,
5600 automatically shifts from ints to longs.
Raymond Hettinger8f669372007-10-03 21:18:11 +00005601
Georg Brandl3ee81df2008-05-17 18:14:43 +00005602- Issue #1686386: Tuple's tp_repr did not take into account the
5603 possibility of having a self-referential tuple, which is possible
5604 from C code. Nor did object's tp_str consider that a type's tp_str
5605 could do something that could lead to an inifinite recursion.
5606 Py_ReprEnter() and Py_EnterRecursiveCall(), respectively, fixed the
5607 issues.
Brett Cannon0b14f242007-09-30 19:45:10 +00005608
Georg Brandl3ee81df2008-05-17 18:14:43 +00005609- Issue #1164: It was possible to trigger deadlock when using the
5610 'print' statement to write to a file since the GIL was not released
5611 as needed. Now PyObject_Print() does the right thing along with
5612 various tp_print implementations of the built-in types and those in
5613 the collections module.
Brett Cannon01531592007-09-17 03:28:34 +00005614
Georg Brandl3ee81df2008-05-17 18:14:43 +00005615- Issue #1147: Exceptions were directly allowing string exceptions in
5616 their throw() method even though string exceptions no longer
5617 allowed.
Brett Cannon4c20bc42007-09-11 21:02:28 +00005618
Georg Brandl3ee81df2008-05-17 18:14:43 +00005619- Issue #1096: Prevent a segfault from getting the repr of a very
5620 deeply nested list by using the recursion counter.
Brett Cannona0c05512007-09-10 21:38:27 +00005621
Brett Cannon1e534b52007-09-07 04:18:30 +00005622- Issue #1202533: Fix infinite recursion calls triggered by calls to
Georg Brandl3ee81df2008-05-17 18:14:43 +00005623 PyObject_Call() never calling back out to Python code to trigger
5624 recursion depth updates/checks. Required the creation of a static
5625 RuntimeError instance in case normalizing an exception put the
5626 recursion check value past its limit. Fixes crashers
5627 infinite_rec_(1|2|4|5).py.
Brett Cannon1e534b52007-09-07 04:18:30 +00005628

Neal Norwitz0ac60192007-05-27 04:08:54 +00005642- Add new attribute names for function objects. All the func_* become
Georg Brandl3ee81df2008-05-17 18:14:43 +00005643 __*__ attributes. (Some already existed, e.g., __doc__ and
5644 __name__.)
Neal Norwitz0ac60192007-05-27 04:08:54 +00005645
Neal Norwitz8b2bfbc2007-05-23 06:35:32 +00005646- Add -3 option to the interpreter to warn about features that are
5647 deprecated and will be changed/removed in Python 3.0.
5648
Georg Brandl2134e752007-05-21 20:34:16 +00005649- Patch #1686487: you can now pass any mapping after '**' in function
5650 calls.
5651
Collin Winter62903052007-05-18 23:11:24 +00005652- except clauses may now be spelled either "except E, target:" or
Georg Brandl3ee81df2008-05-17 18:14:43 +00005653 "except E as target:". This is to provide forwards compatibility
5654 with Python 3.0.

Vinay Sajip8549ce32007-05-06 17:53:37 +00005661- When __slots__ are set to a unicode string, make it work the same as
Neal Norwitzcbd9ee62007-04-14 05:25:50 +00005662 setting a plain string, ie don't expand to single letter identifiers.
5663
Raymond Hettinger13936692007-04-11 18:40:58 +00005664- Request #1191699: Slices can now be pickled.
5665
Raymond Hettinger4db5fe92007-04-12 04:10:00 +00005666- Request #1193128: str.translate() now allows a None argument for
5667 translations that only remove characters without re-mapping the
5668 remaining characters.
5669
Georg Brandl5cb76c12007-03-21 09:00:39 +00005670- Patch #1682205: a TypeError while unpacking an iterable is no longer

5674
Guido van Rossum143b5642007-03-23 04:58:42 +00005675- Bug #1683368: The object.__init__() and object.__new__() methods are
5676 now stricter in rejecting excess arguments. The only time when
5677 either allows excess arguments is when it is not overridden and the
5678 other one is. For backwards compatibility, when both are
5679 overridden, it is a deprecation warning (for now; maybe a Py3k
Guido van Rossum234b1ff2007-03-23 19:39:01 +00005680 warning later). Also, type.__init__() insists on the same signature
5681 as supported by type.__new__().
Guido van Rossum143b5642007-03-23 04:58:42 +00005682
Georg Brandl3ee81df2008-05-17 18:14:43 +00005683- Patch #1675423: PyComplex_AsCComplex() now tries to convert an
5684 object to complex using its __complex__() method before falling back
5685 to the __float__() method. Therefore, the functions in the cmath
5686 module now can operate on objects that define a __complex__()
5687 method.
Georg Brandl2b869942007-03-17 16:08:45 +00005688
Georg Brandl3ee81df2008-05-17 18:14:43 +00005689- Patch #1623563: allow __class__ assignment for classes with

5698 its type.

5704
Georg Brandl7b9c5552007-03-12 14:30:05 +00005705- Bug #1678647: write a newline after printing an exception in any
5706 case, even when converting the value to a string failed.
5707
Georg Brandl871f1bc2007-03-12 13:17:36 +00005708- The dir() function has been extended to call the __dir__() method on
Georg Brandl3ee81df2008-05-17 18:14:43 +00005709 its argument, if it exists. If not, it will work like before. This
5710 allows customizing the output of dir() in the presence of a
5711 __getattr__().

Georg Brandl3ee81df2008-05-17 18:14:43 +00005719- Patch #1491866: change the complex() constructor to allow
5720 parthensized forms. This means complex(repr(x)) now works instead of
5721 raising a ValueError.
Collin Wintere38051d2007-03-09 20:33:07 +00005722
Georg Brandlaa2321b2007-03-07 00:40:28 +00005723- Patch #703779: unset __file__ in __main__ after running a file. This
Georg Brandl3ee81df2008-05-17 18:14:43 +00005724 makes the filenames the warning module prints much more sensible
5725 when a PYTHONSTARTUP file is used.
Georg Brandlaa2321b2007-03-07 00:40:28 +00005726

Georg Brandl0fca97a2007-03-05 22:28:08 +00005738- Patch #1674228: when assigning a slice (old-style), check for the
5739 sq_ass_slice instead of the sq_slice slot.
5740
Georg Brandl3ee81df2008-05-17 18:14:43 +00005741- When printing an unraisable error, don't print exceptions. before
5742 the name. This duplicates the behavior whening normally printing
5743 exceptions.

6371 -- the failure just occurred later, with a more cumbersome
6372 exception.

6585 partial fix for Bug #1574584.
6586
Georg Brandl3ee81df2008-05-17 18:14:43 +00006587- Fix turtle so that time.sleep is imported for the entire library.

Georg Brandl3ee81df2008-05-17 18:14:43 +00006653- Issue #829951: In the smtplib module, SMTP.starttls() now complies
6654 with RFC 3207 and forgets any knowledge obtained from the server not
6655 obtained from the TLS negotiation itself. Patch contributed by Bill
6656 Fenner.
Gregory P. Smith2b3ba582008-01-17 08:03:17 +00006657
Georg Brandl3ee81df2008-05-17 18:14:43 +00006658- Issue #1339: The smtplib.SMTP class has been refactored a bit such
Gregory P. Smithbde4ae42008-01-17 08:35:49 +00006659 that the SMTP.starttls() caller no longer needs to call ehlo()
6660 beforehand. SMTP.starttls() now raises an exception of the server
Georg Brandl3ee81df2008-05-17 18:14:43 +00006661 does not claim to support starttls. Adds the
6662 SMTP.ehlo_or_helo_if_needed() method. Patch contributed by Bill
6663 Fenner.

Georg Brandl3ee81df2008-05-17 18:14:43 +00006705- Patch #976880: ``mmap`` objects now have an ``rfind`` method that
Andrew M. Kuchling5c60bfc2008-01-19 18:18:41 +00006706 works as expected. ``mmap.find`` also takes an optional ``end``

Georg Brandl3ee81df2008-05-17 18:14:43 +00006717- itertools.chain() now has an alternate constructor,

6732 contents before adding elements from the iterable. This fix brings
6733 the behavior into line with that for list.__init__().

6743 complex, tuple, list, dict, set, and frozenset. Formerly, it would
6744 silently miscode subclasses of those types. Now, it raises a
6745 ValueError instead.
Raymond Hettinger12e94202007-11-07 01:13:09 +00006746

Georg Brandl3ee81df2008-05-17 18:14:43 +00006761 time so that opening a database previously created with the DB_DUP
6762 or DB_DUPSORT flag set will keep the proper behavior on subsequent
6763 opens. Specifically: dictionary assignment to a DB object will
6764 replace all values for a given key when the database allows
6765 duplicate values. DB users should use DB.put(k, v) when they want
6766 to store duplicates; not DB[k] = v.
Gregory P. Smithec10a4a2007-11-05 02:32:26 +00006767

6773 characters with ASCII value less than 32. Also, it correctly quotes
6774 dots only if they occur on a single line, as opposed to the previous
6775 behavior of quoting dots if they are the second character of any
6776 line.
Georg Brandl4aef7272007-03-13 22:49:43 +00006777

7099-----
7100
Georg Brandl3ee81df2008-05-17 18:14:43 +00007101- Unified naming convention for free lists and their limits. All free
7102 lists in Object/ are named ``free_list``, the counter ``numfree``
7103 and the upper limit is a macro ``PyName_MAXFREELIST`` inside an
7104 #ifndef block.
Christian Heimes5b970ad2008-02-06 13:33:44 +00007105
Georg Brandl3ee81df2008-05-17 18:14:43 +00007106- ``PySet_Add()`` can now modify a newly created frozenset. Similarly
7107 to ``PyTuple_SetItem``, it can be used to populate a brand new
7108 frozenset; but it does not steal a reference to the added item.
Amaury Forgeot d'Arccab3d982008-02-03 22:51:43 +00007109
Vinay Sajipb7edfc42008-04-02 21:10:23 +00007110- Added ``PySet_Check()`` and ``PyFrozenSet_Check()`` to the set API.

7113 and _FormatV from Python 3.0. Made PyLong_AsSsize_t and
7114 PyLong_FromSsize_t public functions.
Georg Brandl6caad7d2008-01-26 14:19:22 +00007115
7116- Patch #1720595: add T_BOOL to the range of structmember types.
7117
7118- Issue #1534: Added ``PyFloat_GetMax()``, ``PyFloat_GetMin()`` and
7119 ``PyFloat_GetInfo()`` to the float API.
7120
Georg Brandl3ee81df2008-05-17 18:14:43 +00007121- Issue #1521: On 64bit platforms, using PyArgs_ParseTuple with the t#
7122 of w# format code incorrectly truncated the length to an int, even
7123 when PY_SSIZE_T_CLEAN is set. The str.decode method used to return
7124 incorrect results with huge strings.
Georg Brandl6caad7d2008-01-26 14:19:22 +00007125
Georg Brandl3ee81df2008-05-17 18:14:43 +00007126- Issue #1629: Renamed Py_Size, Py_Type and Py_Refcnt to Py_SIZE,
7127 Py_TYPE and Py_REFCNT.

Georg Brandl3ee81df2008-05-17 18:14:43 +00007129- PEP 3123: Provide forward compatibility with Python 3.0, while
7130 keeping backwards compatibility. Add Py_Refcnt, Py_Type, Py_Size,
7131 and PyVarObject_HEAD_INIT.
Georg Brandl6caad7d2008-01-26 14:19:22 +00007132
Georg Brandl3ee81df2008-05-17 18:14:43 +00007133- Py_ssize_t fields work in structmember when HAVE_LONG_LONG is not
7134 defined.
Georg Brandl6caad7d2008-01-26 14:19:22 +00007135
7136- Patch #1733960: Allow T_LONGLONG to accept ints.

7143
7144- Fix some leftovers from the conversion from int to Py_ssize_t
7145 (relevant to strings and sequences of more than 2**31 items).
7146
7147- Make _PyGILState_NoteThreadState() static, it was not used anywhere
7148 outside of pystate.c and should not be necessary.
7149
Georg Brandl3ee81df2008-05-17 18:14:43 +00007150- ``PyImport_Import`` and ``PyImport_ImportModule`` now always do
7151 absolute imports. In earlier versions they might have used relative
7152 imports under some conditions.
Christian Heimes000a0742008-01-03 22:16:32 +00007153
Georg Brandl3ee81df2008-05-17 18:14:43 +00007154- Added case insensitive comparison methods ``PyOS_stricmp(char*,
7155 char*)`` and ``PyOS_strnicmp(char*, char*, Py_ssize_t)``.
Christian Heimes000a0742008-01-03 22:16:32 +00007156
Georg Brandl3ee81df2008-05-17 18:14:43 +00007157- Bug #1542693: remove semi-colon at end of PyImport_ImportModuleEx

Georg Brandl3ee81df2008-05-17 18:14:43 +00007164- Patch #1706: Drop support for Win9x, WinME and NT4. Python now
7165 requires Windows 2000 or greater. The _WINVER and NTDDI_VERSION
7166 macros are set to Win2k for x86/32bit builds and WinXP for AMD64
7167 builds.
Christian Heimes95d64472008-02-09 19:55:22 +00007168

Georg Brandl3ee81df2008-05-17 18:14:43 +00007182- Removed the macfs module. It had been deprecated since Python 2.5.
7183 This lead to the deprecation of macostools.touched() as it relied
7184 solely on macfs and was a no-op under OS X.
