625 handles non-blocking readinto() returning None correctly.
626
Antoine Pitrouf7f390a2010-09-14 14:37:18 +0000627- Issue #9729: Fix the signature of SSLSocket.recvfrom() and
628 SSLSocket.sendto() to match the corresponding socket methods. Also,
629 fix various SSLSocket methods to raise socket.error rather than an
630 unhelpful TypeError when called on an unconnected socket. Original patch
631 by Andrew Bennetts.

639 ZipFile.open()) could return more bytes than requested.
640
Raymond Hettinger20397532010-09-12 02:11:45 +0000641- Issue #9825: removed __del__ from the definition of collections.OrderedDict.
642 This prevents user-created self-referencing ordered dictionaries from
643 becoming permanently uncollectable GC garbage. The downside is that
644 removing __del__ means that the internal doubly-linked list has to wait for
645 GC collection rather than freeing memory immediately when the refcnt drops
646 to zero.
647

651
Antoine Pitrouc818ed42010-09-07 21:40:25 +0000652- Issue #9792: In case of connection failure, socket.create_connection()
653 would swallow the exception and raise a new one, making it impossible
654 to fetch the original errno, or to filter timeout errors. Now the
655 original error is re-raised.
656
Antoine Pitrouf4f61712010-09-07 16:34:47 +0000657- Issue #9758: When fcntl.ioctl() was called with mutable_flag set to True,
658 and the passed buffer was exactly 1024 bytes long, the buffer wouldn't
659 be updated back after the system call. Original patch by Brian Brazil.

666
Daniel Stutzbach66c981b2010-08-31 20:29:39 +0000667- Issue #808164: Fixed socket.close to avoid references to globals, to
668 avoid issues when socket.close is called from a __del__ method.
669
Terry Reedyd2d2ae92010-11-11 23:22:19 +0000670- Issue #2986: difflib.SequenceMatcher gets a new parameter, autojunk, which

672 heuristic. Patch by Terry Reedy and Eli Bendersky

675 falling into recursion.
676
R. David Murray7c4bf552010-08-25 01:45:57 +0000677- Issue #1194222: email.utils.parsedate now returns RFC2822 compliant four
678 character years even if the message contains RFC822 two character years.
679
Daniel Stutzbach91287322010-08-24 21:09:30 +0000680- Issue #8750: Fixed MutableSet's methods to correctly handle
681 reflexive operations, namely x -= x and x ^= x.
682

692 module now correctly return a set. (Patch by Eli Bendersky.)
693
Antoine Pitrou3ebaed62010-08-21 19:17:25 +0000694- Issue #9617: Signals received during a low-level write operation aren't
695 ignored by the buffered IO layer anymore.
696

698 are not held onto after they are deleted elsewhere.
699
Raymond Hettingera54b2da2010-08-17 19:03:06 +0000700- Issue #9626: the view methods for collections.OrderedDict() were returning

713 original read request had been satisfied, which could block indefinitely
714 when the underlying raw IO channel was e.g. a socket. Report and original
715 patch by Jason V. Miller.

Ezio Melottiab2eb0e2010-06-05 19:21:32 +00001105- Issue #8271: during the decoding of an invalid UTF-8 byte sequence, only the

1108 E.g.: '\xf1\x80AB'.decode('utf-8', 'replace') now returns u'\ufffdAB' and
1109 replaces with U+FFFD only the start byte ('\xf1') and the continuation byte

1121 (2**53+1 == complex(2**53) == 2**53), breaking transivity of equality.

Mark Dickinsond2f3e3f2010-05-05 22:23:58 +00001466 (Optimization was unintentionally turned on in gcc --with-pydebug builds in
1467 2.7 beta1 as a result of the issue #1628484 fix, combined with autoconf's
1468 strange choice of default CFLAGS produced by AC_PROG_CC for gcc.)

1488Core and Builtins
1489-----------------
1490
Philip Jenveyaebbaeb2010-04-06 23:24:45 +00001491- Issue #7301: Add environment variable $PYTHONWARNINGS.
1492
Benjamin Peterson3a1dfa22010-04-06 21:50:00 +00001493- Issue #8329: Don't return the same lists from select.select when no fds are
1494 changed.
1495
Georg Brandlfee0f442010-05-22 21:26:21 +00001496- Issue #8259: ``1L << (2**31)`` no longer produces an 'outrageous shift error'
Mark Dickinson82791672010-04-06 16:47:55 +00001497 on 64-bit machines. The shift count for either left or right shift is
1498 permitted to be up to sys.maxsize.
1499
Benjamin Peterson4ceeeb02010-04-03 22:48:51 +00001500- Ensure that tokenization of identifiers is not affected by locale.
1501
Georg Brandlfee0f442010-05-22 21:26:21 +00001502- Issue #1222585: Added LDCXXSHARED for C++ support. Patch by Arfrever.
Tarek Ziadé00002952010-04-03 08:37:59 +00001503
Benjamin Peterson1c7c11e2010-04-03 01:28:57 +00001504- Raise a TypeError when trying to delete a T_STRING_INPLACE struct member.
1505
Georg Brandlfee0f442010-05-22 21:26:21 +00001506- Issue #7994: Issue a PendingDeprecationWarning if object.__format__ is called
1507 with a non-empty format string. This is an effort to future-proof user
1508 code. If a derived class does not currently implement __format__ but later
1509 adds its own __format__, it would most likely break user code that had
Antoine Pitrou01a196a2011-01-02 20:05:11 +00001510 supplied a format string. This will be changed to a DeprecationWarning in
Georg Brandlfee0f442010-05-22 21:26:21 +00001511 Python 3.3 and it will be an error in Python 3.4.
Eric Smithd44b2fc2010-04-02 12:30:56 +00001512
Antoine Pitroua57df2c2010-03-31 21:32:15 +00001513- Issue #8268: Old-style classes (not just instances) now support weak

1525
Victor Stinner66644262010-03-10 22:30:19 +00001526- Issue #3137: Don't ignore errors at startup, especially a keyboard interrupt
Georg Brandlba83f822010-03-14 09:50:54 +00001527 (SIGINT). If an error occurs while importing the site module, the error is
1528 printed and Python exits. Initialize the GIL before importing the site
Victor Stinner66644262010-03-10 22:30:19 +00001529 module.

1543
Georg Brandlfee0f442010-05-22 21:26:21 +00001544- Issue #8257: The Decimal construct now accepts a float instance directly,
1545 converting that float to a Decimal of equal value:
Mark Dickinson8a950712010-04-03 15:47:46 +00001546
1547 >>> Decimal(1.1)
1548 Decimal('1.100000000000000088817841970012523233890533447265625')
1549
Raymond Hettinger34c35b22010-04-03 10:22:00 +00001550- collections.Counter() now supports a subtract() method.
1551
Georg Brandlfee0f442010-05-22 21:26:21 +00001552- The functools module now has a total_ordering() class decorator to simplify
1553 the specification of rich comparisons.
Raymond Hettingera551f312010-04-04 18:34:45 +00001554
Georg Brandlfee0f442010-05-22 21:26:21 +00001555- The functools module also adds cmp_to_key() as a tool to transition old-style
1556 comparison functions to new-style key-functions.
Raymond Hettingera551f312010-04-04 18:34:45 +00001557
Georg Brandlfee0f442010-05-22 21:26:21 +00001558- Issue #8294: The Fraction constructor now accepts Decimal and float instances
1559 directly.
Mark Dickinson7c63eee2010-04-02 22:27:36 +00001560
Georg Brandlfee0f442010-05-22 21:26:21 +00001561- Issue #7279: Comparisons involving a Decimal signaling NaN now signal
1562 InvalidOperation instead of returning False. (Comparisons involving a quiet
1563 NaN are unchanged.) Also, Decimal quiet NaNs are now hashable; Decimal
1564 signaling NaNs remain unhashable.
Mark Dickinsone096e822010-04-02 10:17:07 +00001565
Georg Brandlfee0f442010-05-22 21:26:21 +00001566- Issue #2531: Comparison operations between floats and Decimal instances now
1567 return a result based on the numeric values of the operands; previously they
1568 returned an arbitrary result based on the relative ordering of id(float) and
1569 id(Decimal).
Mark Dickinson99d80962010-04-02 08:53:22 +00001570
Barry Warsawf7f2d6f2010-03-31 21:07:16 +00001571- Issue #8233: When run as a script, py_compile.py optionally takes a single
Georg Brandlfee0f442010-05-22 21:26:21 +00001572 argument `-` which tells it to read files to compile from stdin. Each line is
1573 read on demand and the named file is compiled immediately. (Original patch by
1574 Piotr Ożarowski).
Barry Warsawf7f2d6f2010-03-31 21:07:16 +00001575
Georg Brandlfee0f442010-05-22 21:26:21 +00001576- Issue #3135: Add ``inspect.getcallargs()``, which binds arguments to a

Florent Xicluna58b65662010-03-30 16:29:03 +00001579- Backwards incompatible change: Unicode codepoints line tabulation (0x0B) and
1580 form feed (0x0C) are now considered linebreaks, as specified in Unicode
Georg Brandlfee0f442010-05-22 21:26:21 +00001581 Standard Annex #14. See issue #7643. http://www.unicode.org/reports/tr14/
Florent Xicluna22b24382010-03-30 08:24:06 +00001582
Georg Brandlfee0f442010-05-22 21:26:21 +00001583- Comparisons using one of <, <=, >, >= between a complex instance and a
1584 Fractions instance now raise TypeError instead of returning True/False. This
1585 makes Fraction <=> complex comparisons consistent with int <=> complex, float
1586 <=> complex, and complex <=> complex comparisons.
Mark Dickinson9588d992010-03-27 11:14:37 +00001587
Michael Foorde6410c52010-03-29 20:04:23 +00001588- Addition of ``WeakSet`` to the ``weakref`` module.

1596
Antoine Pitrou513d9ae2010-03-22 19:59:46 +00001597- Issue #7512: shutil.copystat() could raise an OSError when the filesystem
Georg Brandlfee0f442010-05-22 21:26:21 +00001598 didn't support chflags() (for example ZFS under FreeBSD). The error is now
1599 silenced.
Antoine Pitrou513d9ae2010-03-22 19:59:46 +00001600
Florent Xicluna9e7a4c92010-03-22 16:07:38 +00001601- Issue #7703: ctypes supports both buffer() and memoryview(). The former is

Georg Brandlfee0f442010-05-22 21:26:21 +00001642 for ``TimedRotatingFileHandler`` by using the modification time of an existing
1643 log file to compute the next rollover time. If the log file does not exist,
1644 the current time is used as the basis for the computation.
Vinay Sajip9098ee42010-03-12 06:01:21 +00001645

Mark Dickinson4846a8e2010-04-03 14:05:10 +00001685- Issue #8300: When passing a non-integer argument to struct.pack with any
1686 integer format code, struct.pack first attempts to convert the non-integer
1687 using its __index__ method. If that method is non-existent or raises
1688 TypeError it goes on to try the __int__ method, as described below.
1689
Georg Brandlba83f822010-03-14 09:50:54 +00001690- Issue #1530559: When passing a non-integer argument to struct.pack with *any*
1691 integer format code (one of 'bBhHiIlLqQ'), struct.pack attempts to use the
1692 argument's __int__ method to convert to an integer before packing. It also
Georg Brandlfee0f442010-05-22 21:26:21 +00001693 produces a DeprecationWarning in this case. (In Python 2.6, the behaviour was
1694 inconsistent: __int__ was used for some integer codes but not for others, and
1695 the set of integer codes for which it was used differed between native packing
1696 and standard packing.)

1949 could crash in many places because of the ``PyByteArray_AS_STRING()`` macro
1950 returning NULL. The macro now returns a statically allocated empty string
1951 instead.

Georg Brandlba83f822010-03-14 09:50:54 +00002004 file position when calling `truncate()`. It would previously change the file
2005 position to the given argument, which goes against the tradition of
Antoine Pitrouf3fa0742010-01-31 22:26:04 +00002006 ftruncate() and other truncation APIs. Patch by Pascal Chambon.
2007
Georg Brandlba83f822010-03-14 09:50:54 +00002008- Issue #7610: Reworked implementation of the internal ``zipfile.ZipExtFile``
2009 class used to represent files stored inside an archive. The new
2010 implementation is significantly faster and can be wrapped in a
2011 ``io.BufferedReader`` object for more speedups. It also solves an issue
2012 where interleaved calls to ``read()`` and ``readline()`` give wrong results.
2013 Patch by Nir Aides.

Georg Brandlba83f822010-03-14 09:50:54 +00002023- Issue #7748: Since unicode values are supported for some metadata options in
2024 Distutils, the DistributionMetadata get_* methods will now return an utf-8
2025 encoded string for them. This ensures that the upload and register commands
2026 send the correct values to PyPI without any error.

Georg Brandlba83f822010-03-14 09:50:54 +00002297- Issue #7117: ``repr(x)`` for a float x returns a result based on the shortest
2298 decimal string that's guaranteed to round back to x under correct rounding
2299 (with round-half-to-even rounding mode). Previously it gave a string based on
2300 rounding x to 17 decimal digits. repr(x) for a complex number behaves
2301 similarly. On platforms where the correctly-rounded strtod and dtoa code is
2302 not supported (see below), repr is unchanged.
Mark Dickinsonb678de82009-11-19 18:41:49 +00002303
Georg Brandlba83f822010-03-14 09:50:54 +00002304- Issue #7117: On almost all platforms: float-to-string and string-to-float
2305 conversions within Python are now correctly rounded. Places these conversions
2306 occur include: str for floats and complex numbers; the float and complex
2307 constructors; old-style and new-style numeric formatting; serialization and
2308 deserialization of floats and complex numbers using marshal, pickle and json;
2309 parsing of float and imaginary literals in Python code; Decimal-to-float
2310 conversion.
Mark Dickinsonb678de82009-11-19 18:41:49 +00002311
Georg Brandlba83f822010-03-14 09:50:54 +00002312 The conversions use a Python-adapted version of David Gay's well-known dtoa.c,
2313 providing correctly-rounded strtod and dtoa C functions. This code is
2314 supported on Windows, and on Unix-like platforms using gcc, icc or suncc as
2315 the C compiler. There may be a small number of platforms on which correct
2316 operation of this code cannot be guaranteed, so the code is not used: notably,
2317 this applies to platforms where the C double format is not IEEE 754 binary64,
2318 and to platforms on x86 hardware where the x87 FPU is set to 64-bit precision
2319 and Python's configure script is unable to determine how to change the FPU
2320 precision. On these platforms conversions use the platform strtod and dtoa,
2321 as before.
Mark Dickinsonb678de82009-11-19 18:41:49 +00002322
Georg Brandlba83f822010-03-14 09:50:54 +00002323- Issue #7117: Backport round implementation from Python 3.x. ``round()`` now
2324 uses the correctly-rounded string <-> float conversions described above (when
2325 available), and so produces correctly rounded results that will display nicely
2326 under the float repr. There are two related small changes: (1) round now
2327 accepts any class with an ``__index__()`` method for its second argument (but
2328 no longer accepts floats for the second argument), and (2) an excessively
2329 large second integer argument (e.g., ``round(1.234, 10**100)``) no longer
2330 raises an exception.

2480 of 12. Previously, the behavior the same but with a default precision of 6.

Georg Brandlba83f822010-03-14 09:50:54 +00002604- Issue #4935: The overflow checking code in the expandtabs() method common to
2605 str, bytes and bytearray could be optimized away by the compiler, letting the
2606 interpreter segfault instead of raising an error.

2622
Georg Brandlba83f822010-03-14 09:50:54 +00002623- Issue #1180193: When importing a module from a .pyc (or .pyo) file with an
2624 existing .py counterpart, override the co_filename attributes of all code
2625 objects if the original filename is obsolete (which can happen if the file has
2626 been renamed, moved, or if it is accessed through different paths). Patch by

2667 ``offsetof(PyStringObject, ob_sval) + 1`` when allocating memory for str
2668 instances. On a typical machine this saves 3 bytes of memory (on average) per

Amaury Forgeot d'Arcdc619012008-11-22 20:01:18 +00002671- Issue #3996: On Windows, the PyOS_CheckStack function would cause the

2673 instead of throwing a MemoryError.
2674
Georg Brandlba83f822010-03-14 09:50:54 +00002675- Issue #3689: The list reversed iterator now supports __length_hint__ instead

2680
Georg Brandlba83f822010-03-14 09:50:54 +00002681- Issue #4233: Changed semantic of ``_fileio.FileIO``'s ``close()`` method on
2682 file objects with closefd=False. The file descriptor is still kept open but
2683 the file object behaves like a closed file. The ``FileIO`` object also got a
2684 new readonly attribute ``closefd``.

2703
Benjamin Peterson399b1fe2008-10-25 02:53:28 +00002704- Using ``nonlocal`` as a variable name will now raise a Py3k SyntaxWarning
Georg Brandl7fb00ad2008-10-25 07:00:52 +00002705 because it is a reserved word in 3.x.

Georg Brandlba83f822010-03-14 09:50:54 +00002707- On windows, ``os.chdir()`` given unicode was not working if
2708 GetCurrentDirectoryW returned a path longer than MAX_PATH. (But It's doubtful
2709 this code path is really executed because I cannot move to such directory on
2710 win2k)

Georg Brandlba83f822010-03-14 09:50:54 +00002712- Issue #4069: When ``set.remove(element)`` is used with a set element, the
2713 element is temporarily replaced with an equivalent frozenset. But the
2714 eventual KeyError would always report the empty ``frozenset()`` as the missing
2715 key. Now it correctly refers to the initial element.

Walter Dörwalded960ac2009-05-03 22:36:33 +00002735- Issue #5108: Handle %s like %S and %R in PyUnicode_FromFormatV(): Call
2736 PyUnicode_DecodeUTF8() once, remember the result and output it in a second
2737 step. This avoids problems with counting UTF-8 bytes that ignores the effect
2738 of using the replace error handler in PyUnicode_DecodeUTF8().
2739
Walter Dörwald726ba8e2009-05-06 14:32:35 +00002740- Issue #3739: The unicode-internal encoder now reports the number of characters

2742
Georg Brandlba83f822010-03-14 09:50:54 +00002743- Issue #2422: When compiled with the ``--with-valgrind`` option, the pymalloc
2744 allocator will be automatically disabled when running under Valgrind. This
2745 gives improved memory leak detection when running under Valgrind, while taking
2746 advantage of pymalloc at other times.

Georg Brandlba83f822010-03-14 09:50:54 +00003969 leak-chasing test runs give sensible results. The previous method of reaping
3970 threads could return successfully while some Thread objects were still
3971 referenced. This also introduces a new private function: ``thread._count()``.

3978
R. David Murray14dcd432009-10-14 13:58:07 +00003979- Issue #7058: Added save/restore for things like sys.argv and cwd to

3981 and a new section in the summary report at the end.

Guilherme Polo7f146ab2009-06-21 17:22:50 +00003988- Issue #5450: Moved tests involving loading tk from Lib/test/test_tcl to
3989 Lib/lib-tk/test/test_tkinter/test_loadtk. With this, these tests demonstrate
Georg Brandlba83f822010-03-14 09:50:54 +00003990 the same behaviour as test_ttkguionly (and now also test_tk) which is to skip
3991 the tests if DISPLAY is defined but can't be used.

3997 import both normal and optimised versions of modules. test_heapq and
3998 test_warnings have been adjusted to use it, tests for other modules with both
3999 C and Python implementations in the stdlib can be adjusted to use it over
4000 time.

4009 should cause a test to be skipped are now done using import_module from test
4010 support, which does the conversion.

4112
Amaury Forgeot d'Arc05e34492008-09-10 22:04:45 +00004113- Issue #3743: In a few places, PY_FORMAT_SIZE_T was incorrectly used with
4114 PyString_FromFormat or PyErr_Format to display size_t values. The macro
4115 PY_FORMAT_SIZE_T is designed to select the correct format for the OS
4116 ``printf`` function, whereas PyString_FromFormat has an independent
4117 implementation and uses "%zd" on all platforms for size_t values.
4118 This makes a difference on win64, where ``printf`` needs "%Id" to display
4119 64bit values.

Benjamin Peterson97179b02008-09-09 20:55:01 +00004121- Issue #3634: _weakref.ref(Exception).__init__() gave invalid return value on

4125 object; previously an int would be returned for small values. the __long__
4126 method is allowed to return either an int or a long, but the behaviour of

Antoine Pitroud4ae97b2008-08-29 18:39:48 +00004136 was correctly parsed but parsing of subsequent arguments failed.
4137
Vinay Sajip35e3b032008-09-01 14:33:59 +00004138- Issue #2534: speed up isinstance() and issubclass() by 50-70%, so as to
Antoine Pitrou0668c622008-08-26 22:42:08 +00004139 match Python 2.5 speed despite the __instancecheck__ / __subclasscheck__
4140 mechanism. In the process, fix a bug where isinstance() and issubclass(),
4141 when given a tuple of classes as second argument, were looking up
4142 __instancecheck__ / __subclasscheck__ on the tuple rather than on each
4143 type object.

Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00004282What's New in Python 2.6 beta 3?
4283================================
4284
Barry Warsaw07a4a382008-08-21 01:15:08 +00004285*Release date: 20-Aug-2008*
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00004286
4287Core and Builtins
4288-----------------
4289
Guido van Rossumf8402962008-08-20 15:01:50 +00004290- Issue #1878: Remove Py_TPFLAGS_HAVE_VERSION_TAG from
4291 Py_TPFLAGS_DEFAULT when not building the core. This means 3rd party
4292 extensions do not automatically benefit from the class attribute
4293 cache; they will have to explicitly add Py_TPFLAGS_HAVE_VERSION_TAG
4294 to their tp_flags field if they care. This is a backwards
4295 compatibility feature; in 3.0, all types will use the cache by
4296 default.
4297
Benjamin Petersonf647dc12008-08-20 01:27:30 +00004298- Keyword arguments can now follow starred arguments. (``f(a, *args,
4299 keyword=23)`` is now valid syntax.)
4300
Thomas Heller0ad5ae02008-08-19 19:25:04 +00004301- ctypes function pointers that are COM methods have a boolean True
4302 value again.
4303
Martin v. Löwisf91d46a2008-08-12 14:49:50 +00004304- Issue #3139: Make buffer-interface thread-safe wrt. PyArg_ParseTuple,
4305 by denying s# to parse objects that have a releasebuffer procedure,
4306 and introducing s*.
4307
Georg Brandl1e13ea92008-08-11 09:07:59 +00004308- Issue #3537: Fix an assertion failure when an empty but presized dict
4309 object was stored in the freelist.
4310
Mark Dickinsonb6467572008-08-04 21:30:09 +00004311- Issue #1481296: Make long(float('nan')) and int(float('nan')) raise
4312 ValueError consistently across platforms.
4313
Amaury Forgeot d'Arc39fd6722008-07-31 21:28:03 +00004314- Issue #3479: On platforms where sizeof(int) is smaller than sizeof(long)
4315 (64bit Unix, for example), unichr() would truncate its argument and return
4316 u'\x00' for unichr(2**32). Now it properly raises an OverflowError.
4317
Neal Norwitze7d8be82008-07-31 17:17:14 +00004318- Apply security patches from Apple.
4319
Amaury Forgeot d'Arc246daed2008-07-31 00:42:16 +00004320- Issue #2542: Now that issubclass() may call arbitrary code, ensure that
4321 PyErr_ExceptionMatches returns 0 when an exception occurs there.
4322
Antoine Pitrou92f82162008-07-25 22:22:08 +00004323- Issue #1819: function calls with several named parameters are now on
4324 average 35% faster (as measured by pybench).
4325
Amaury Forgeot d'Arce4921fe2008-07-21 22:00:38 +00004326- Issue #2378: An unexpected UnboundLocalError or NameError could appear when
4327 the python debugger steps into a class statement: the free variables (local
4328 variables defined in an outer scope) would be deleted from the outer scope.
4329
Gregory P. Smith0470bab2008-07-22 04:46:32 +00004330- Issue #2620: Overflow checking when allocating or reallocating memory
4331 was not always being done properly in some python types and extension
4332 modules. PyMem_MALLOC, PyMem_REALLOC, PyMem_NEW and PyMem_RESIZE have
4333 all been updated to perform better checks and places in the code that
4334 would previously leak memory on the error path when such an allocation
4335 failed have been fixed.

4339
Hirokazu Yamamoto838c79f2008-08-20 13:14:07 +00004340- Issue #3612: Added some missing basic types in ctypes.wintypes.
4341
Benjamin Petersone977ad42008-08-20 01:42:01 +00004342- The methods ``is_in_tuple()``, ``is_vararg()``, and ``is_keywordarg()`` of
4343 symtable.Symbol have been deprecated for removal in 3.0 and the next release.
4344
Amaury Forgeot d'Arc351ffb82008-08-18 19:23:47 +00004345- Issue #2234: distutils failed for some versions of the cygwin compiler. The
4346 version reported by these tools does not necessarily follow the python
4347 version numbering scheme, so the module is less strict when parsing it.
4348
Nick Coghlanf70385a2008-08-18 12:42:46 +00004349- Issue #2235: Added Py3k warnings for types which will become unhashable
4350 under the stricter __hash__ inheritance rules in 3.0. Several types
4351 which did not meet the rules for hash invariants and were already
4352 unhashable in 3.0 have now been explicitly flagged as unhashable in
4353 2.6 as well (collections.Mapping, collections.Set, unittest.TestSuite,
4354 xml.dom.minidom.NamedNodeMap, numbers.Number, UserList.UserList)
4355
Brett Cannon88f801d2008-08-18 00:46:22 +00004356- Update __all__ for cookielib, csv, os, urllib2, and weakref to include things
4357 imported into the module but exposed as part of the module's API.
4358
Brett Cannon7b96f072008-08-18 00:41:11 +00004359- Remove an unneeded import of abc.ABCMeta from 'inspect'.
4360
Brett Cannon46225e72008-08-18 00:36:52 +00004361- Remove unneeded imports of 'sys' and 'warnings' from 'io'.
4362
Brett Cannon25c9d6a2008-08-17 22:10:11 +00004363- Remove unneeded imports of 'warnings' from shelve, filecmp, and dummy_thread.
4364
Hirokazu Yamamoto41a81eb2008-08-17 13:10:46 +00004365- Issue #3575: Incremental decoder's decode function now takes bytearray
4366 by using 's*' instead of 't#'.
4367
Mark Dickinson3e4caeb2009-02-21 20:27:01 +00004368- Issue #2222: Fixed reference leak when occurred os.rename()
Hirokazu Yamamoto7f30a682008-08-17 09:46:56 +00004369 fails unicode conversion on 2nd parameter. (windows only)
4370
Georg Brandl222e2082010-08-01 22:27:39 +00004371- Issue #2464: urllib2 now supports a malformation in the URL received
Facundo Batista94f243a2008-08-17 03:38:39 +00004372 in a redirect.
4373
Brett Cannonabe423e2008-08-16 21:47:07 +00004374- Silence the DeprecationWarning raised when importing mimetools in
Brett Cannon721b1452008-08-16 22:00:27 +00004375 BaseHTTPServer, cgi (and rfc822), httplib.
Brett Cannonabe423e2008-08-16 21:47:07 +00004376
Facundo Batistaeb90b782008-08-16 14:44:07 +00004377- Issue #2776: fixed small issue when handling an URL with double slash
4378 after a 302 response in the case of not going through a proxy.
4379
Antoine Pitroub90a8be2008-08-15 21:03:21 +00004380- Issue #2676: in the email package, content-type parsing was hanging on
4381 pathological input because of quadratic or exponential behaviour of a
4382 regular expression.
4383
Antoine Pitrou11ec65d2008-08-14 21:04:30 +00004384- Issue #3476: binary buffered reading through the new "io" library is now
4385 thread-safe.
4386
Brett Cannonbf3157b2008-08-14 05:00:03 +00004387- Silence the DeprecationWarning of rfc822 when it is imported by mimetools
4388 since mimetools itself is deprecated. Because modules are cached, all
4389 subsequent imports of rfc822 will not raise a visible DeprecationWarning.
4390
Antoine Pitrou9fcd4b32008-08-11 17:21:36 +00004391- Issue #3134: shutil referenced undefined WindowsError symbol.
4392
Robert Schuppenies14646332008-08-10 11:01:53 +00004393- Issue #1342811: Fix leak in Tkinter.Menu.delete. Commands associated to
4394 menu entries were not deleted.
4395
Brett Cannon83e81842008-08-09 23:30:55 +00004396- Copied the implementation of reduce() to _functools.reduce() to have a
4397 version that did not raise a DeprecationWarning under -3.
4398
Antoine Pitrou76b8bee2008-08-09 17:27:23 +00004399- Issue #3205: When iterating over a BZ2File fails allocating memory, raise
4400 a MemoryError rather than silently stop the iteration.
4401
Guido van Rossum59ce9012008-08-09 14:55:34 +00004402- Issue #3487: sre "bytecode" validator. Passing invalid "re-bytecode"
4403 to _sre.compile() will now be rejected. This should not affect anybody
4404 since the re.compile() function never generates invalid re-bytecode.
4405
Skip Montanaroa032bf42008-08-08 22:52:51 +00004406- Issue #3436: Make csv.DictReader's fieldnames attribute a property so that
4407 upon first access it can be automatically initialized from the csv file if
4408 it wasn't initialized during instantiation.
4409
Brett Cannon3aa2a492008-08-06 22:28:09 +00004410- Issue #2338: Create imp.reload() to help with transitioning to Python 3.0 as
4411 the reload() built-in has been removed.
4412
Brett Cannon7e30b672008-08-04 21:52:25 +00004413- Changed code in the following modules/packages to remove warnings raised
Brett Cannonc1b76e42008-08-09 23:06:16 +00004414 while running under the ``-3`` flag: aifc, asynchat, asyncore, bdb, bsddb,

Brett Cannon7e30b672008-08-04 21:52:25 +00004420
Lars Gustäbel727bd0b2008-08-02 11:26:39 +00004421- Issue #3039: Fix tarfile.TarFileCompat.writestr() which always
4422 raised an AttributeError.
4423
Benjamin Peterson01a24322008-07-28 23:35:27 +00004424- Issue #2523: Fix quadratic behaviour when read()ing a binary file without
Antoine Pitroude781a42008-08-09 12:43:23 +00004425 asking for a specific length. This problem only affected files opened
4426 using the new "io" module, not the built-in open() function.
Benjamin Peterson01a24322008-07-28 23:35:27 +00004427
Mark Dickinsonfe84cce2008-07-27 06:39:07 +00004428- Issue #3449: Update decimal module to use most recent specification
4429 (v. 1.68) and tests (v. 2.58) from IBM.
4430
Georg Brandl222e2082010-08-01 22:27:39 +00004431- Issue #3437: Bug fix in robotparser parsing of Allow: lines.
Skip Montanarof9ac43f2008-07-27 00:50:41 +00004432

4435
Georg Brandlf9efabb2008-07-23 15:16:45 +00004436- Deprecate the "ast" parser function aliases.
4437
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00004438- Issue #3120: On 64-bit Windows the subprocess module was truncating handles.
4439
4440- Issue #3303: Fix a crash in locale.strcoll() when calling it with
4441 invalid arguments.
4442
4443- Issue #3302: Fix several crashes when calling locale's gettext functions
4444 with None arguments.
4445
4446- Issue #3389: Allow resolving dotted names for handlers in logging
4447 configuration files.
4448
4449- Deprecate the sunaudio module for removal in Python 3.0.
4450
Antoine Pitrou5fdfa3e2008-07-25 19:42:26 +00004451- Issue #3394: zipfile.writestr sets external attributes when passed a
4452 file name rather than a ZipInfo instance, so files are extracted with
4453 mode 0600 rather than 000 under Unix.
4454
Gregory P. Smitha36f8fe2008-08-04 00:13:29 +00004455- Issue #1857: subprocess.Popen.poll gained an additional _deadstate keyword
4456 argument in python 2.5, this broke code that subclassed Popen to include its
4457 own poll method. Fixed my moving _deadstate to an _internal_poll method.

4468 interaction with the tp_hash slot (added in 2.6b2) are now documented
4469
Nick Coghlan2a0c2b12008-08-04 12:47:17 +00004470- Issue #643841: The language reference now provides more detailed
4471 coverage of the lookup process for special methods. The disclaimers
4472 regarding lack of coverage of new-style classes have also been
4473 removed, since the coverage is now fairly reasonable.

Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00004479*Release date: 17-Jul-2008*

4482-----------------
4483
Georg Brandl3e483f62008-07-16 22:57:41 +00004484- Issue #3156: Fix inconsistent behavior of the bytearray type: all
4485 its methods now allow for items objects that can be converted to
4486 an integer using operator.index().
4487
Mark Dickinson64b7e502008-07-16 09:40:03 +00004488- Issue #3360: Fix incorrect parsing of '020000000000.0', which
4489 produced a ValueError instead of giving the correct float.
4490
Eric Smitha5fa5a22008-07-16 00:11:49 +00004491- Issue #3083: Add alternate (#) formatting for bin, oct, hex output
4492 for str.format(). This adds the prefix 0b, 0o, or 0x, respectively.
4493
Mark Dickinson7103aa42008-07-15 19:08:33 +00004494- Issue #3008: the float type has a new instance method 'float.hex'
4495 and a new class method 'float.fromhex' to convert floating-point
4496 numbers to and from hexadecimal strings, respectively.
4497
Nick Coghlan6d6bd442008-07-15 15:40:22 +00004498- Issue #2235: __hash__ is once again inherited by default. To allow
4499 collections.Hashable to remain meaningful in the presence of the
4500 default hash implementation (object.__hash__), it is now possible
4501 to explicit block inheritance of hash by setting __hash__=None at
4502 the Python level, or tp_hash=PyObject_HashNotImplemented at the C
4503 level.
4504
Nick Coghlanb028f502008-07-13 14:52:36 +00004505- Issue #3221: Issue a RuntimeWarning instead of raising SystemError if
4506 the parent module cannot be found while performing an absolute import.
4507 This means that an incorrectly defined __package__ attribute will
4508 now only prevent relative imports in that module rather than causing
4509 all imports from that module to fail.
4510
Nick Coghlan14ff9942008-07-08 14:21:42 +00004511- Issue #2517: Allow unicode messages in Exceptions again by correctly
4512 bypassing the instance dictionary when looking up __unicode__ on
4513 new-style classes.
4514
Amaury Forgeot d'Arcbdd941f2008-07-01 20:38:04 +00004515- Issue #3242: Fix a crash inside the print statement, if sys.stdout is
4516 set to a custom object whose write() method happens to install
4517 another file in sys.stdout.
4518
Amaury Forgeot d'Arc1f40c8a2008-06-30 22:42:40 +00004519- Issue #3088: Corrected a race condition in classes derived from
4520 threading.local: the first member set by a thread could be saved in
4521 another thread's dictionary.
4522
Mark Dickinson1ec2fcd2008-06-20 14:53:43 +00004523- Issue #3004: Minor change to slice.indices(): the start and stop
4524 arguments are now treated identically, making the behaviour easier
4525 to describe and understand. For example, slice(None, -10,
4526 1).indices(9) now returns (0, 0, 1) instead of (0, -1, 1), and
4527 slice(None, 10, -1).indices(10) returns (9, 9, -1) instead of (9,
4528 10, -1).
4529
Georg Brandl278fc502008-07-19 12:46:12 +00004530- Issue #3219: Calling a function with repeated keyword arguments,
4531 f(a=2, a=23), would not cause a syntax error. This was a regression
4532 from 2.4 caused by the switch to the new compiler.

Georg Brandl5cc774e2008-06-11 20:28:06 +00004982 PPC64 and x86_64 support in one binary).
Ronald Oussoren5640ce22008-06-05 12:58:24 +00004983
4984 This is controlled by the configure argument ``--with-universal-archs``:
4985

4987
4988 - ``--with-universal-archs=32-bit``: install 2-way universal, 32-bit (the default)
4989
4990 - ``--with-universal-archs=64-bit``: install 2-way universal, 64-bit

5031 two handlers that derive the same default base class.
Amaury Forgeot d'Arc96865852008-04-22 21:14:41 +00005032
Christian Heimese74c8f22008-04-19 02:23:57 +00005033- Added kill, terminate and send_signal(sig) to subprocess.Popen.
5034

Georg Brandl3ee81df2008-05-17 18:14:43 +00005044- Issue #1631171: Re-implement the 'warnings' module in C (the
5045 original Python code has been kept as backup). This will allow for
5046 using the 'warning's machinery in such places as the parser where
5047 use of pure Python code is not possible. Both the ``showarning()``
5048 and ``formatwarning()`` gain an optional 'line' argument which is
5049 not called by default for backwards-compatibility reasons. Setting
5050 ``warnings.showwarning()`` to an implementation that lacks support
5051 for the ``line`` argument will raise a DeprecationWarning.

Gregory P. Smithd59fefb2008-04-22 08:11:33 +00005076- The getpass module has been improved on Unix. It now uses /dev/tty

Georg Brandl3ee81df2008-05-17 18:14:43 +00005114- Issue #2550: The approach used by client/server code for obtaining
5115 ports to listen on in network-oriented tests has been refined in an
5116 effort to facilitate running multiple instances of the entire
5117 regression test suite in parallel without issue.
5118 test_support.bind_port() has been fixed such that it will always
5119 return a unique port -- which wasn't always the case with the
5120 previous implementation, especially if socket options had been set
5121 that affected address reuse (i.e. SO_REUSEADDR, SO_REUSEPORT). The
5122 new implementation of bind_port() will actually raise an exception
5123 if it is passed an AF_INET/SOCK_STREAM socket with either the
5124 SO_REUSEADDR or SO_REUSEPORT socket option set. Furthermore, if
5125 available, bind_port() will set the SO_EXCLUSIVEADDRUSE option on
5126 the socket it's been passed. This currently only applies to
5127 Windows. This option prevents any other sockets from binding to the
5128 host/port we've bound to, thus removing the possibility of the
5129 'non-deterministic' behaviour, as Microsoft puts it, that occurs
5130 when a second SOCK_STREAM socket binds and accepts to a host/port
5131 that's already been bound by another socket. The optional preferred
5132 port parameter to bind_port() has been removed. Under no
5133 circumstances should tests be hard coding ports!
5134
5135 test_support.find_unused_port() has also been introduced, which will
5136 pass a temporary socket object to bind_port() in order to obtain an
5137 unused port. The temporary socket object is then closed and
5138 deleted, and the port is returned. This method should only be used
5139 for obtaining an unused port in order to pass to an external program
5140 (i.e. the -accept [port] argument to openssl's s_server mode) or as
5141 a parameter to a server-oriented class that doesn't give you direct
5142 access to the underlying socket used.
5143
5144 Finally, test_support.HOST has been introduced, which should be used
5145 for the host argument of any relevant socket calls (i.e. bind and
5146 connect).
Trent Nelsone41b0062008-04-08 23:47:30 +00005147
5148 The following tests were updated to following the new conventions:
Georg Brandl3ee81df2008-05-17 18:14:43 +00005149 test_socket, test_smtplib, test_asyncore, test_ssl, test_httplib,
Trent Nelsone41b0062008-04-08 23:47:30 +00005150 test_poplib, test_ftplib, test_telnetlib, test_socketserver,
5151 test_asynchat and test_socket_ssl.
5152
Georg Brandl3ee81df2008-05-17 18:14:43 +00005153 It is now possible for multiple instances of the regression test
5154 suite to run in parallel without issue.

Thomas Heller78b8f442008-03-05 14:53:39 +00005358- The bundled libffi copy is now in sync with the recently released
5359 libffi3.0.4 version, apart from some small changes to
Georg Brandl3ee81df2008-05-17 18:14:43 +00005360 Modules/_ctypes/libffi/configure.ac. On OS X, preconfigured libffi
5361 files are used. On all linux systems the --with-system-ffi
5362 configure option defaults to "yes".

Fred Drakea8ee94b2008-03-01 02:45:07 +00005423- Issue #2051: pyc and pyo files are no longer created with permission
Barry Warsaw52973612008-03-01 02:23:38 +00005424 644. The mode is now inherited from the py file.

Eric Smitha73fbe72008-02-23 03:09:44 +00005433- Added the future_builtins module, which contains hex() and oct().
5434 These are the PEP 3127 version of these functions, designed to be
5435 compatible with the hex() and oct() builtins from Python 3.0. They
5436 differ slightly in their output formats from the existing, unchanged
5437 Python 2.6 builtins. The expected usage of the future_builtins
5438 module is:
5439 from future_builtins import hex, oct
5440
Eric Smith7ef40bf2008-02-20 23:34:22 +00005441- Issue #1600: Modifed PyOS_ascii_formatd to use at most 2 digit
5442 exponents for exponents with absolute value < 100. Follows C99
5443 standard. This is a change on Windows, which would use 3 digits.
5444 Also, added 'n' to the formats that PyOS_ascii_formatd understands,
5445 so that any alterations it does to the resulting string will be
5446 available in stringlib/formatter.h (for float.__format__).
5447
Eric Smith5a3c1352008-02-19 13:21:56 +00005448- Implemented PEP 3101, Advanced String Formatting. This adds a new
5449 builtin format(); a format() method for str and unicode; a
5450 __format__() method to object, str, unicode, int, long, float, and
5451 datetime; the class string.Formatter; and the C API
5452 PyObject_Format().
5453
Georg Brandl3ee81df2008-05-17 18:14:43 +00005454- Fixed several potential crashes, all caused by specially crafted
5455 __del__ methods exploiting objects in temporarily inconsistent
5456 state.
Amaury Forgeot d'Arc632fad32008-02-16 20:55:24 +00005457
Vinay Sajipb7edfc42008-04-02 21:10:23 +00005458- Issue #2115: Important speedup in setting __slot__ attributes. Also
Georg Brandl3ee81df2008-05-17 18:14:43 +00005459 prevent a possible crash: an Abstract Base Class would try to access
5460 a slot on a registered virtual subclass.
Amaury Forgeot d'Arc60d6c7f2008-02-15 21:22:45 +00005461

Georg Brandl3ee81df2008-05-17 18:14:43 +00005465- Clear all free lists during a gc.collect() of the highest generation
5466 in order to allow pymalloc to free more arenas. Python may give back
5467 memory to the OS earlier.
Christian Heimes3b718a72008-02-14 12:47:33 +00005468
Georg Brandl3ee81df2008-05-17 18:14:43 +00005469- Issue #2045: Fix an infinite recursion triggered when printing a
5470 subclass of collections.defaultdict, if its default_factory is set
5471 to a bound method.
Amaury Forgeot d'Arcb01aa432008-02-08 00:56:02 +00005472
Christian Heimesf75dbef2008-02-08 00:11:31 +00005473- Fixed a minor memory leak in dictobject.c. The content of the free
5474 list was not freed on interpreter shutdown.
5475
Georg Brandl21e99f42010-03-07 15:23:59 +00005476- Limit free list of method and built-in function objects to 256
Georg Brandl3ee81df2008-05-17 18:14:43 +00005477 entries each.
Christian Heimes6075a822008-02-06 12:44:34 +00005478
Georg Brandl3ee81df2008-05-17 18:14:43 +00005479- Patch #1953: Added ``sys._compact_freelists()`` and the C API
5480 functions ``PyInt_CompactFreeList`` and ``PyFloat_CompactFreeList``
Christian Heimes422051a2008-02-04 18:00:12 +00005481 to compact the internal free lists of pre-allocted ints and floats.
5482
Georg Brandl3ee81df2008-05-17 18:14:43 +00005483- Issue #1983: Fixed return type of fork(), fork1() and forkpty()
5484 calls. Python expected the return type int but the fork familie
5485 returns pi_t.
Christian Heimes951cc0f2008-01-31 23:08:23 +00005486
Georg Brandl3ee81df2008-05-17 18:14:43 +00005487- Issue #1678380: Fix a bug that identifies 0j and -0j when they
5488 appear in the same code unit.

Georg Brandl3ee81df2008-05-17 18:14:43 +00005499- Patch #1473257: generator objects gain a gi_code attribute. This is
5500 the same object as the func_code attribute of the function that
5501 produced the generator.
Georg Brandl0cdf9a32008-01-26 14:14:20 +00005502
Georg Brandl3ee81df2008-05-17 18:14:43 +00005503- Issue #1920: "while 0" statements were completely removed by the
5504 compiler, even in the presence of an "else" clause, which is
5505 supposed to be run when the condition is false. Now the compiler
5506 correctly emits bytecode for the "else" suite.
Amaury Forgeot d'Arc31eaafe2008-01-24 22:59:25 +00005507
Guido van Rossumeead05f2008-01-24 18:21:02 +00005508- A few crashers fixed: weakref_in_del.py (issue #1377858);
5509 loosing_dict_ref.py (issue #1303614, test67.py);
5510 borrowed_ref_[34].py (not in tracker).
5511
Vinay Sajipd7cf32e2008-01-24 12:43:33 +00005512- Issue #1069410: The "can't load dll" message box on Windows is
Christian Heimesb2302ba2008-01-23 17:15:06 +00005513 suppressed while an extension is loaded by calling SetErrorMode in
5514 dynload_win.c. The error is still reported properly.
5515
Georg Brandl3ee81df2008-05-17 18:14:43 +00005516- Issue #1915: Python compiles with --enable-unicode=no again. However
Christian Heimes082c9b02008-01-23 14:20:50 +00005517 several extension methods and modules do not work without unicode
5518 support.
5519
Georg Brandl26543b12008-01-21 18:36:51 +00005520- Issue #1882: when compiling code from a string, encoding cookies in the
5521 second line of code were not always recognized correctly.
5522
Georg Brandl14404b62008-01-19 19:27:05 +00005523- Issue #1679: "0x" was taken as a valid integer literal.
5524
Georg Brandl6caad7d2008-01-26 14:19:22 +00005525- Issue #1865: ``bytes`` as an alias for ``str`` and b"" as an alias "" were
Christian Heimes288e89a2008-01-18 18:24:07 +00005526 added.
5527
Christian Heimesc94e2b52008-01-14 04:13:37 +00005528- sys.float_info / PyFloat_GetInfo: The floating point information
5529 object was converted from a dict to a specialized structseq object.
5530
Georg Brandl3ee81df2008-05-17 18:14:43 +00005531- Patch #1816: Added sys.flags structseq. It exposes the status of
5532 most command line arguments and PYTHON* environment variables.
Christian Heimesf31b69f2008-01-14 03:42:48 +00005533
Georg Brandl3ee81df2008-05-17 18:14:43 +00005534- Objects/structseq.c: Implemented new structseq representation. The

Georg Brandl3ee81df2008-05-17 18:14:43 +00005560 and INF. float("nan"), float("inf") and float("-inf") now work on
5561 every platform with IEEE 754 semantics.
Christian Heimes0a8143f2007-12-18 23:22:54 +00005562
Georg Brandl3ee81df2008-05-17 18:14:43 +00005563- Compiler now generates simpler and faster code for dictionary
5564 literals. The oparg for BUILD_MAP now indicates an estimated
5565 dictionary size. There is a new opcode, STORE_MAP, for adding
5566 entries to the dictionary.

Georg Brandl3ee81df2008-05-17 18:14:43 +00005595- Patch #1739468: Directories and zipfiles containing a __main__.py
5596 file can now be directly executed by passing their name to the
5597 interpreter. The directory/zipfile is automatically inserted as the
5598 first entry in sys.path.

Georg Brandl3ee81df2008-05-17 18:14:43 +00005600- Issue #1265: Fix a problem with sys.settrace, if the tracing
5601 function uses a generator expression when at the same time the
5602 executed code is closing a paused generator.
Amaury Forgeot d'Arc0d75f092007-11-13 21:54:28 +00005603
Raymond Hettinger1760c8a2007-11-08 02:52:43 +00005604- sets and frozensets now have an isdisjoint() method.
5605

5607
Neal Norwitz44f326e2007-10-05 05:29:17 +00005608- Fix warnings found by the new version of the Coverity checker.
5609
Georg Brandl21e99f42010-03-07 15:23:59 +00005610- The enumerate() built-in function is no longer bounded to sequences
Georg Brandl3ee81df2008-05-17 18:14:43 +00005611 smaller than LONG_MAX. Formerly, it raised an OverflowError. Now,
5612 automatically shifts from ints to longs.
Raymond Hettinger8f669372007-10-03 21:18:11 +00005613
Georg Brandl3ee81df2008-05-17 18:14:43 +00005614- Issue #1686386: Tuple's tp_repr did not take into account the
5615 possibility of having a self-referential tuple, which is possible
5616 from C code. Nor did object's tp_str consider that a type's tp_str
5617 could do something that could lead to an inifinite recursion.
5618 Py_ReprEnter() and Py_EnterRecursiveCall(), respectively, fixed the
5619 issues.
Brett Cannon0b14f242007-09-30 19:45:10 +00005620
Georg Brandl3ee81df2008-05-17 18:14:43 +00005621- Issue #1164: It was possible to trigger deadlock when using the
5622 'print' statement to write to a file since the GIL was not released
5623 as needed. Now PyObject_Print() does the right thing along with
5624 various tp_print implementations of the built-in types and those in
5625 the collections module.
Brett Cannon01531592007-09-17 03:28:34 +00005626
Georg Brandl3ee81df2008-05-17 18:14:43 +00005627- Issue #1147: Exceptions were directly allowing string exceptions in
5628 their throw() method even though string exceptions no longer
5629 allowed.
Brett Cannon4c20bc42007-09-11 21:02:28 +00005630
Georg Brandl3ee81df2008-05-17 18:14:43 +00005631- Issue #1096: Prevent a segfault from getting the repr of a very
5632 deeply nested list by using the recursion counter.
Brett Cannona0c05512007-09-10 21:38:27 +00005633
Brett Cannon1e534b52007-09-07 04:18:30 +00005634- Issue #1202533: Fix infinite recursion calls triggered by calls to
Georg Brandl3ee81df2008-05-17 18:14:43 +00005635 PyObject_Call() never calling back out to Python code to trigger
5636 recursion depth updates/checks. Required the creation of a static
5637 RuntimeError instance in case normalizing an exception put the
5638 recursion check value past its limit. Fixes crashers
5639 infinite_rec_(1|2|4|5).py.
Brett Cannon1e534b52007-09-07 04:18:30 +00005640

Neal Norwitz0ac60192007-05-27 04:08:54 +00005654- Add new attribute names for function objects. All the func_* become
Georg Brandl3ee81df2008-05-17 18:14:43 +00005655 __*__ attributes. (Some already existed, e.g., __doc__ and
5656 __name__.)
Neal Norwitz0ac60192007-05-27 04:08:54 +00005657
Neal Norwitz8b2bfbc2007-05-23 06:35:32 +00005658- Add -3 option to the interpreter to warn about features that are
5659 deprecated and will be changed/removed in Python 3.0.
5660
Georg Brandl2134e752007-05-21 20:34:16 +00005661- Patch #1686487: you can now pass any mapping after '**' in function
5662 calls.
5663
Collin Winter62903052007-05-18 23:11:24 +00005664- except clauses may now be spelled either "except E, target:" or
Georg Brandl3ee81df2008-05-17 18:14:43 +00005665 "except E as target:". This is to provide forwards compatibility
5666 with Python 3.0.
Collin Winter62903052007-05-18 23:11:24 +00005667
Brett Cannon229cee22007-05-05 01:34:02 +00005668- Deprecate BaseException.message as per PEP 352.
5669
Georg Brandl3ee81df2008-05-17 18:14:43 +00005670- Issue #1303614: don't expose object's __dict__ when the dict is
Georg Brandl21e99f42010-03-07 15:23:59 +00005671 inherited from a built-in base.
Armin Rigo9790a272007-05-02 19:23:31 +00005672
Vinay Sajip8549ce32007-05-06 17:53:37 +00005673- When __slots__ are set to a unicode string, make it work the same as
Neal Norwitzcbd9ee62007-04-14 05:25:50 +00005674 setting a plain string, ie don't expand to single letter identifiers.
5675
Raymond Hettinger13936692007-04-11 18:40:58 +00005676- Request #1191699: Slices can now be pickled.
5677
Raymond Hettinger4db5fe92007-04-12 04:10:00 +00005678- Request #1193128: str.translate() now allows a None argument for
5679 translations that only remove characters without re-mapping the
5680 remaining characters.
5681
Georg Brandl5cb76c12007-03-21 09:00:39 +00005682- Patch #1682205: a TypeError while unpacking an iterable is no longer

5684
Neal Norwitzaa754b72007-03-21 06:39:48 +00005685- Remove unused file Python/fmod.c.
5686
Guido van Rossum143b5642007-03-23 04:58:42 +00005687- Bug #1683368: The object.__init__() and object.__new__() methods are
5688 now stricter in rejecting excess arguments. The only time when
5689 either allows excess arguments is when it is not overridden and the
5690 other one is. For backwards compatibility, when both are
5691 overridden, it is a deprecation warning (for now; maybe a Py3k
Guido van Rossum234b1ff2007-03-23 19:39:01 +00005692 warning later). Also, type.__init__() insists on the same signature
5693 as supported by type.__new__().
Guido van Rossum143b5642007-03-23 04:58:42 +00005694
Georg Brandl3ee81df2008-05-17 18:14:43 +00005695- Patch #1675423: PyComplex_AsCComplex() now tries to convert an
5696 object to complex using its __complex__() method before falling back
5697 to the __float__() method. Therefore, the functions in the cmath
5698 module now can operate on objects that define a __complex__()
5699 method.
Georg Brandl2b869942007-03-17 16:08:45 +00005700
Georg Brandl3ee81df2008-05-17 18:14:43 +00005701- Patch #1623563: allow __class__ assignment for classes with

5709 ``object.__reduce_ex__()`` is called with an object that is faking
5710 its type.
Žiga Seilnacht20f43d32007-03-15 11:44:55 +00005711
Georg Brandl3ee81df2008-05-17 18:14:43 +00005712- Patch #1680015: Don't modify __slots__ tuple if it contains an

5716
Georg Brandl7b9c5552007-03-12 14:30:05 +00005717- Bug #1678647: write a newline after printing an exception in any
5718 case, even when converting the value to a string failed.
5719
Georg Brandl871f1bc2007-03-12 13:17:36 +00005720- The dir() function has been extended to call the __dir__() method on
Georg Brandl3ee81df2008-05-17 18:14:43 +00005721 its argument, if it exists. If not, it will work like before. This
5722 allows customizing the output of dir() in the presence of a
5723 __getattr__().

Georg Brandl3ee81df2008-05-17 18:14:43 +00005731- Patch #1491866: change the complex() constructor to allow
5732 parthensized forms. This means complex(repr(x)) now works instead of
5733 raising a ValueError.
Collin Wintere38051d2007-03-09 20:33:07 +00005734
Georg Brandlaa2321b2007-03-07 00:40:28 +00005735- Patch #703779: unset __file__ in __main__ after running a file. This
Georg Brandl3ee81df2008-05-17 18:14:43 +00005736 makes the filenames the warning module prints much more sensible
5737 when a PYTHONSTARTUP file is used.
Georg Brandlaa2321b2007-03-07 00:40:28 +00005738

Georg Brandl0fca97a2007-03-05 22:28:08 +00005750- Patch #1674228: when assigning a slice (old-style), check for the
5751 sq_ass_slice instead of the sq_slice slot.
5752
Georg Brandl3ee81df2008-05-17 18:14:43 +00005753- When printing an unraisable error, don't print exceptions. before
5754 the name. This duplicates the behavior whening normally printing
5755 exceptions.

6383 -- the failure just occurred later, with a more cumbersome
6384 exception.

Georg Brandl3ee81df2008-05-17 18:14:43 +00006665- Issue #829951: In the smtplib module, SMTP.starttls() now complies
6666 with RFC 3207 and forgets any knowledge obtained from the server not
6667 obtained from the TLS negotiation itself. Patch contributed by Bill
6668 Fenner.
Gregory P. Smith2b3ba582008-01-17 08:03:17 +00006669
Georg Brandl3ee81df2008-05-17 18:14:43 +00006670- Issue #1339: The smtplib.SMTP class has been refactored a bit such
Gregory P. Smithbde4ae42008-01-17 08:35:49 +00006671 that the SMTP.starttls() caller no longer needs to call ehlo()
6672 beforehand. SMTP.starttls() now raises an exception of the server
Georg Brandl3ee81df2008-05-17 18:14:43 +00006673 does not claim to support starttls. Adds the
6674 SMTP.ehlo_or_helo_if_needed() method. Patch contributed by Bill

6755 complex, tuple, list, dict, set, and frozenset. Formerly, it would
6756 silently miscode subclasses of those types. Now, it raises a
6757 ValueError instead.
Raymond Hettinger12e94202007-11-07 01:13:09 +00006758

Georg Brandl3ee81df2008-05-17 18:14:43 +00006773 time so that opening a database previously created with the DB_DUP
6774 or DB_DUPSORT flag set will keep the proper behavior on subsequent
6775 opens. Specifically: dictionary assignment to a DB object will
6776 replace all values for a given key when the database allows
6777 duplicate values. DB users should use DB.put(k, v) when they want
6778 to store duplicates; not DB[k] = v.
Gregory P. Smithec10a4a2007-11-05 02:32:26 +00006779

6785 characters with ASCII value less than 32. Also, it correctly quotes
6786 dots only if they occur on a single line, as opposed to the previous
6787 behavior of quoting dots if they are the second character of any
6788 line.
Georg Brandl4aef7272007-03-13 22:49:43 +00006789

7111-----
7112
Georg Brandl3ee81df2008-05-17 18:14:43 +00007113- Unified naming convention for free lists and their limits. All free
7114 lists in Object/ are named ``free_list``, the counter ``numfree``
7115 and the upper limit is a macro ``PyName_MAXFREELIST`` inside an
7116 #ifndef block.
Christian Heimes5b970ad2008-02-06 13:33:44 +00007117
Georg Brandl3ee81df2008-05-17 18:14:43 +00007118- ``PySet_Add()`` can now modify a newly created frozenset. Similarly
7119 to ``PyTuple_SetItem``, it can be used to populate a brand new
7120 frozenset; but it does not steal a reference to the added item.

7132
Georg Brandl3ee81df2008-05-17 18:14:43 +00007133- Issue #1521: On 64bit platforms, using PyArgs_ParseTuple with the t#
7134 of w# format code incorrectly truncated the length to an int, even
7135 when PY_SSIZE_T_CLEAN is set. The str.decode method used to return
7136 incorrect results with huge strings.
Georg Brandl6caad7d2008-01-26 14:19:22 +00007137
Georg Brandl3ee81df2008-05-17 18:14:43 +00007138- Issue #1629: Renamed Py_Size, Py_Type and Py_Refcnt to Py_SIZE,

7156- Fix some leftovers from the conversion from int to Py_ssize_t
7157 (relevant to strings and sequences of more than 2**31 items).
7158
7159- Make _PyGILState_NoteThreadState() static, it was not used anywhere
7160 outside of pystate.c and should not be necessary.
7161
Georg Brandl3ee81df2008-05-17 18:14:43 +00007162- ``PyImport_Import`` and ``PyImport_ImportModule`` now always do
7163 absolute imports. In earlier versions they might have used relative
7164 imports under some conditions.
Christian Heimes000a0742008-01-03 22:16:32 +00007165
Georg Brandl3ee81df2008-05-17 18:14:43 +00007166- Added case insensitive comparison methods ``PyOS_stricmp(char*,
7167 char*)`` and ``PyOS_strnicmp(char*, char*, Py_ssize_t)``.
Christian Heimes000a0742008-01-03 22:16:32 +00007168
Georg Brandl3ee81df2008-05-17 18:14:43 +00007169- Bug #1542693: remove semi-colon at end of PyImport_ImportModuleEx

Georg Brandl3ee81df2008-05-17 18:14:43 +00007176- Patch #1706: Drop support for Win9x, WinME and NT4. Python now
7177 requires Windows 2000 or greater. The _WINVER and NTDDI_VERSION
7178 macros are set to Win2k for x86/32bit builds and WinXP for AMD64
7179 builds.
Christian Heimes95d64472008-02-09 19:55:22 +00007180

Georg Brandl3ee81df2008-05-17 18:14:43 +00007194- Removed the macfs module. It had been deprecated since Python 2.5.
7195 This lead to the deprecation of macostools.touched() as it relied
7196 solely on macfs and was a no-op under OS X.
