Raymond Hettinger20397532010-09-12 02:11:45 +0000653- Issue #9825: removed __del__ from the definition of collections.OrderedDict.
654 This prevents user-created self-referencing ordered dictionaries from
655 becoming permanently uncollectable GC garbage. The downside is that
656 removing __del__ means that the internal doubly-linked list has to wait for
657 GC collection rather than freeing memory immediately when the refcnt drops
658 to zero.

667 original error is re-raised.
668

Daniel Stutzbach66c981b2010-08-31 20:29:39 +0000679- Issue #808164: Fixed socket.close to avoid references to globals, to

R. David Murray7c4bf552010-08-25 01:45:57 +0000689- Issue #1194222: email.utils.parsedate now returns RFC2822 compliant four
690 character years even if the message contains RFC822 two character years.
691
Daniel Stutzbach91287322010-08-24 21:09:30 +0000692- Issue #8750: Fixed MutableSet's methods to correctly handle

Ezio Melottiab2eb0e2010-06-05 19:21:32 +00001117- Issue #8271: during the decoding of an invalid UTF-8 byte sequence, only the
1118 start byte and the continuation byte(s) are now considered invalid, instead
1119 of the number of bytes specified by the start byte.
1120 E.g.: '\xf1\x80AB'.decode('utf-8', 'replace') now returns u'\ufffdAB' and
1121 replaces with U+FFFD only the start byte ('\xf1') and the continuation byte

1132 objects. (1) The comparison could incorrectly return True in some cases
1133 (2**53+1 == complex(2**53) == 2**53), breaking transivity of equality.

1432 to follow. This improves compatibility with patch tools.

Mark Dickinsond2f3e3f2010-05-05 22:23:58 +00001478 (Optimization was unintentionally turned on in gcc --with-pydebug builds in
1479 2.7 beta1 as a result of the issue #1628484 fix, combined with autoconf's
1480 strange choice of default CFLAGS produced by AC_PROG_CC for gcc.)

1500Core and Builtins
1501-----------------
1502
Philip Jenveyaebbaeb2010-04-06 23:24:45 +00001503- Issue #7301: Add environment variable $PYTHONWARNINGS.
1504
Benjamin Peterson3a1dfa22010-04-06 21:50:00 +00001505- Issue #8329: Don't return the same lists from select.select when no fds are
1506 changed.
1507
Georg Brandlfee0f442010-05-22 21:26:21 +00001508- Issue #8259: ``1L << (2**31)`` no longer produces an 'outrageous shift error'
Mark Dickinson82791672010-04-06 16:47:55 +00001509 on 64-bit machines. The shift count for either left or right shift is
1510 permitted to be up to sys.maxsize.
1511
Benjamin Peterson4ceeeb02010-04-03 22:48:51 +00001512- Ensure that tokenization of identifiers is not affected by locale.
1513
Georg Brandlfee0f442010-05-22 21:26:21 +00001514- Issue #1222585: Added LDCXXSHARED for C++ support. Patch by Arfrever.
Tarek Ziadé00002952010-04-03 08:37:59 +00001515
Benjamin Peterson1c7c11e2010-04-03 01:28:57 +00001516- Raise a TypeError when trying to delete a T_STRING_INPLACE struct member.
1517
Georg Brandlfee0f442010-05-22 21:26:21 +00001518- Issue #7994: Issue a PendingDeprecationWarning if object.__format__ is called
1519 with a non-empty format string. This is an effort to future-proof user
1520 code. If a derived class does not currently implement __format__ but later
1521 adds its own __format__, it would most likely break user code that had
Antoine Pitrou01a196a2011-01-02 20:05:11 +00001522 supplied a format string. This will be changed to a DeprecationWarning in
Georg Brandlfee0f442010-05-22 21:26:21 +00001523 Python 3.3 and it will be an error in Python 3.4.
Eric Smithd44b2fc2010-04-02 12:30:56 +00001524
Antoine Pitroua57df2c2010-03-31 21:32:15 +00001525- Issue #8268: Old-style classes (not just instances) now support weak

1537
Victor Stinner66644262010-03-10 22:30:19 +00001538- Issue #3137: Don't ignore errors at startup, especially a keyboard interrupt
Georg Brandlba83f822010-03-14 09:50:54 +00001539 (SIGINT). If an error occurs while importing the site module, the error is
1540 printed and Python exits. Initialize the GIL before importing the site

1555
Georg Brandlfee0f442010-05-22 21:26:21 +00001556- Issue #8257: The Decimal construct now accepts a float instance directly,
1557 converting that float to a Decimal of equal value:
Mark Dickinson8a950712010-04-03 15:47:46 +00001558
1559 >>> Decimal(1.1)
1560 Decimal('1.100000000000000088817841970012523233890533447265625')
1561
Raymond Hettinger34c35b22010-04-03 10:22:00 +00001562- collections.Counter() now supports a subtract() method.
1563
Georg Brandlfee0f442010-05-22 21:26:21 +00001564- The functools module now has a total_ordering() class decorator to simplify
1565 the specification of rich comparisons.
Raymond Hettingera551f312010-04-04 18:34:45 +00001566
Georg Brandlfee0f442010-05-22 21:26:21 +00001567- The functools module also adds cmp_to_key() as a tool to transition old-style
1568 comparison functions to new-style key-functions.
Raymond Hettingera551f312010-04-04 18:34:45 +00001569
Georg Brandlfee0f442010-05-22 21:26:21 +00001570- Issue #8294: The Fraction constructor now accepts Decimal and float instances
1571 directly.
Mark Dickinson7c63eee2010-04-02 22:27:36 +00001572
Georg Brandlfee0f442010-05-22 21:26:21 +00001573- Issue #7279: Comparisons involving a Decimal signaling NaN now signal
1574 InvalidOperation instead of returning False. (Comparisons involving a quiet
1575 NaN are unchanged.) Also, Decimal quiet NaNs are now hashable; Decimal
1576 signaling NaNs remain unhashable.
Mark Dickinsone096e822010-04-02 10:17:07 +00001577
Georg Brandlfee0f442010-05-22 21:26:21 +00001578- Issue #2531: Comparison operations between floats and Decimal instances now
1579 return a result based on the numeric values of the operands; previously they
1580 returned an arbitrary result based on the relative ordering of id(float) and
1581 id(Decimal).
Mark Dickinson99d80962010-04-02 08:53:22 +00001582
Barry Warsawf7f2d6f2010-03-31 21:07:16 +00001583- Issue #8233: When run as a script, py_compile.py optionally takes a single
Georg Brandlfee0f442010-05-22 21:26:21 +00001584 argument `-` which tells it to read files to compile from stdin. Each line is
1585 read on demand and the named file is compiled immediately. (Original patch by
1586 Piotr Ożarowski).

Florent Xicluna58b65662010-03-30 16:29:03 +00001591- Backwards incompatible change: Unicode codepoints line tabulation (0x0B) and
1592 form feed (0x0C) are now considered linebreaks, as specified in Unicode
Georg Brandlfee0f442010-05-22 21:26:21 +00001593 Standard Annex #14. See issue #7643. http://www.unicode.org/reports/tr14/
Florent Xicluna22b24382010-03-30 08:24:06 +00001594
Georg Brandlfee0f442010-05-22 21:26:21 +00001595- Comparisons using one of <, <=, >, >= between a complex instance and a
1596 Fractions instance now raise TypeError instead of returning True/False. This
1597 makes Fraction <=> complex comparisons consistent with int <=> complex, float
1598 <=> complex, and complex <=> complex comparisons.
Mark Dickinson9588d992010-03-27 11:14:37 +00001599

Georg Brandlfee0f442010-05-22 21:26:21 +00001654 for ``TimedRotatingFileHandler`` by using the modification time of an existing
1655 log file to compute the next rollover time. If the log file does not exist,
1656 the current time is used as the basis for the computation.
Vinay Sajip9098ee42010-03-12 06:01:21 +00001657

Mark Dickinson4846a8e2010-04-03 14:05:10 +00001697- Issue #8300: When passing a non-integer argument to struct.pack with any
1698 integer format code, struct.pack first attempts to convert the non-integer

1703 integer format code (one of 'bBhHiIlLqQ'), struct.pack attempts to use the
1704 argument's __int__ method to convert to an integer before packing. It also
Georg Brandlfee0f442010-05-22 21:26:21 +00001705 produces a DeprecationWarning in this case. (In Python 2.6, the behaviour was
1706 inconsistent: __int__ was used for some integer codes but not for others, and
1707 the set of integer codes for which it was used differed between native packing
1708 and standard packing.)

Georg Brandlba83f822010-03-14 09:50:54 +00002016 file position when calling `truncate()`. It would previously change the file
2017 position to the given argument, which goes against the tradition of
Antoine Pitrouf3fa0742010-01-31 22:26:04 +00002018 ftruncate() and other truncation APIs. Patch by Pascal Chambon.
2019

2021 class used to represent files stored inside an archive. The new
2022 implementation is significantly faster and can be wrapped in a
2023 ``io.BufferedReader`` object for more speedups. It also solves an issue
2024 where interleaved calls to ``read()`` and ``readline()`` give wrong results.

Georg Brandlba83f822010-03-14 09:50:54 +00002035- Issue #7748: Since unicode values are supported for some metadata options in
2036 Distutils, the DistributionMetadata get_* methods will now return an utf-8
2037 encoded string for them. This ensures that the upload and register commands
2038 send the correct values to PyPI without any error.

Georg Brandlba83f822010-03-14 09:50:54 +00002309- Issue #7117: ``repr(x)`` for a float x returns a result based on the shortest
2310 decimal string that's guaranteed to round back to x under correct rounding
2311 (with round-half-to-even rounding mode). Previously it gave a string based on
2312 rounding x to 17 decimal digits. repr(x) for a complex number behaves
2313 similarly. On platforms where the correctly-rounded strtod and dtoa code is
2314 not supported (see below), repr is unchanged.
Mark Dickinsonb678de82009-11-19 18:41:49 +00002315
Georg Brandlba83f822010-03-14 09:50:54 +00002316- Issue #7117: On almost all platforms: float-to-string and string-to-float
2317 conversions within Python are now correctly rounded. Places these conversions
2318 occur include: str for floats and complex numbers; the float and complex
2319 constructors; old-style and new-style numeric formatting; serialization and
2320 deserialization of floats and complex numbers using marshal, pickle and json;
2321 parsing of float and imaginary literals in Python code; Decimal-to-float
2322 conversion.
Mark Dickinsonb678de82009-11-19 18:41:49 +00002323
Georg Brandlba83f822010-03-14 09:50:54 +00002324 The conversions use a Python-adapted version of David Gay's well-known dtoa.c,
2325 providing correctly-rounded strtod and dtoa C functions. This code is
2326 supported on Windows, and on Unix-like platforms using gcc, icc or suncc as
2327 the C compiler. There may be a small number of platforms on which correct
2328 operation of this code cannot be guaranteed, so the code is not used: notably,
2329 this applies to platforms where the C double format is not IEEE 754 binary64,
2330 and to platforms on x86 hardware where the x87 FPU is set to 64-bit precision
2331 and Python's configure script is unable to determine how to change the FPU
2332 precision. On these platforms conversions use the platform strtod and dtoa,
2333 as before.

Georg Brandlba83f822010-03-14 09:50:54 +00002335- Issue #7117: Backport round implementation from Python 3.x. ``round()`` now
2336 uses the correctly-rounded string <-> float conversions described above (when
2337 available), and so produces correctly rounded results that will display nicely
2338 under the float repr. There are two related small changes: (1) round now
2339 accepts any class with an ``__index__()`` method for its second argument (but
2340 no longer accepts floats for the second argument), and (2) an excessively
2341 large second integer argument (e.g., ``round(1.234, 10**100)``) no longer
2342 raises an exception.

Georg Brandlba83f822010-03-14 09:50:54 +00002489- Issue #5920: For ``float.__format__()``, change the behavior with the empty
2490 presentation type (that is, not one of 'e', 'f', 'g', or 'n') to be like 'g'
2491 but with at least one decimal point and with a default precision
2492 of 12. Previously, the behavior the same but with a default precision of 6.
2493 This more closely matches ``str()``, and reduces surprises when adding
2494 alignment flags to the empty presentation type. This also affects the new
2495 complex.__format__ in the same way.

Georg Brandlba83f822010-03-14 09:50:54 +00002635- Issue #1180193: When importing a module from a .pyc (or .pyo) file with an
2636 existing .py counterpart, override the co_filename attributes of all code
2637 objects if the original filename is obsolete (which can happen if the file has

2692
Georg Brandlba83f822010-03-14 09:50:54 +00002693- Issue #4233: Changed semantic of ``_fileio.FileIO``'s ``close()`` method on
2694 file objects with closefd=False. The file descriptor is still kept open but
2695 the file object behaves like a closed file. The ``FileIO`` object also got a
2696 new readonly attribute ``closefd``.

2715
Benjamin Peterson399b1fe2008-10-25 02:53:28 +00002716- Using ``nonlocal`` as a variable name will now raise a Py3k SyntaxWarning

Georg Brandlba83f822010-03-14 09:50:54 +00002719- On windows, ``os.chdir()`` given unicode was not working if
2720 GetCurrentDirectoryW returned a path longer than MAX_PATH. (But It's doubtful
2721 this code path is really executed because I cannot move to such directory on
2722 win2k)

Georg Brandlba83f822010-03-14 09:50:54 +00002724- Issue #4069: When ``set.remove(element)`` is used with a set element, the
2725 element is temporarily replaced with an equivalent frozenset. But the
2726 eventual KeyError would always report the empty ``frozenset()`` as the missing
2727 key. Now it correctly refers to the initial element.

Walter Dörwalded960ac2009-05-03 22:36:33 +00002747- Issue #5108: Handle %s like %S and %R in PyUnicode_FromFormatV(): Call
2748 PyUnicode_DecodeUTF8() once, remember the result and output it in a second
2749 step. This avoids problems with counting UTF-8 bytes that ignores the effect
2750 of using the replace error handler in PyUnicode_DecodeUTF8().
2751
Walter Dörwald726ba8e2009-05-06 14:32:35 +00002752- Issue #3739: The unicode-internal encoder now reports the number of characters

2754
Georg Brandlba83f822010-03-14 09:50:54 +00002755- Issue #2422: When compiled with the ``--with-valgrind`` option, the pymalloc
2756 allocator will be automatically disabled when running under Valgrind. This
2757 gives improved memory leak detection when running under Valgrind, while taking
2758 advantage of pymalloc at other times.

Georg Brandlba83f822010-03-14 09:50:54 +00003290- Issue #5679: The methods unittest.TestCase.addCleanup and doCleanups were
3291 added. addCleanup allows you to add cleanup functions that will be called
Michael Foord07ef4872009-05-02 22:43:34 +00003292 unconditionally (after setUp if setUp fails, otherwise after tearDown). This
3293 allows for much simpler resource allocation and deallocation during tests.

Michael Foord345b2fe2009-04-02 03:20:38 +00003308 and assertFalse messages are now useful. TestCase has a longMessage attribute.
3309 This defaults to False, but if set to True useful error messages are shown in
3310 addition to explicit messages passed to assert methods.

3982 threads could return successfully while some Thread objects were still

Georg Brandlba83f822010-03-14 09:50:54 +00004002 the same behaviour as test_ttkguionly (and now also test_tk) which is to skip
4003 the tests if DISPLAY is defined but can't be used.

4021 should cause a test to be skipped are now done using import_module from test
4022 support, which does the conversion.

4124
Amaury Forgeot d'Arc05e34492008-09-10 22:04:45 +00004125- Issue #3743: In a few places, PY_FORMAT_SIZE_T was incorrectly used with
4126 PyString_FromFormat or PyErr_Format to display size_t values. The macro
4127 PY_FORMAT_SIZE_T is designed to select the correct format for the OS
4128 ``printf`` function, whereas PyString_FromFormat has an independent
4129 implementation and uses "%zd" on all platforms for size_t values.
4130 This makes a difference on win64, where ``printf`` needs "%Id" to display
4131 64bit values.

Benjamin Peterson97179b02008-09-09 20:55:01 +00004133- Issue #3634: _weakref.ref(Exception).__init__() gave invalid return value on

4137 object; previously an int would be returned for small values. the __long__
4138 method is allowed to return either an int or a long, but the behaviour of

Antoine Pitroud4ae97b2008-08-29 18:39:48 +00004148 was correctly parsed but parsing of subsequent arguments failed.
4149
Vinay Sajip35e3b032008-09-01 14:33:59 +00004150- Issue #2534: speed up isinstance() and issubclass() by 50-70%, so as to
Antoine Pitrou0668c622008-08-26 22:42:08 +00004151 match Python 2.5 speed despite the __instancecheck__ / __subclasscheck__
4152 mechanism. In the process, fix a bug where isinstance() and issubclass(),
4153 when given a tuple of classes as second argument, were looking up
4154 __instancecheck__ / __subclasscheck__ on the tuple rather than on each
4155 type object.

Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00004294What's New in Python 2.6 beta 3?
4295================================
4296
Barry Warsaw07a4a382008-08-21 01:15:08 +00004297*Release date: 20-Aug-2008*
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00004298
4299Core and Builtins
4300-----------------
4301
Guido van Rossumf8402962008-08-20 15:01:50 +00004302- Issue #1878: Remove Py_TPFLAGS_HAVE_VERSION_TAG from
4303 Py_TPFLAGS_DEFAULT when not building the core. This means 3rd party
4304 extensions do not automatically benefit from the class attribute
4305 cache; they will have to explicitly add Py_TPFLAGS_HAVE_VERSION_TAG
4306 to their tp_flags field if they care. This is a backwards
4307 compatibility feature; in 3.0, all types will use the cache by
4308 default.
4309
Benjamin Petersonf647dc12008-08-20 01:27:30 +00004310- Keyword arguments can now follow starred arguments. (``f(a, *args,
4311 keyword=23)`` is now valid syntax.)
4312
Thomas Heller0ad5ae02008-08-19 19:25:04 +00004313- ctypes function pointers that are COM methods have a boolean True
4314 value again.
4315
Martin v. Löwisf91d46a2008-08-12 14:49:50 +00004316- Issue #3139: Make buffer-interface thread-safe wrt. PyArg_ParseTuple,
4317 by denying s# to parse objects that have a releasebuffer procedure,
4318 and introducing s*.
4319
Georg Brandl1e13ea92008-08-11 09:07:59 +00004320- Issue #3537: Fix an assertion failure when an empty but presized dict
4321 object was stored in the freelist.
4322
Mark Dickinsonb6467572008-08-04 21:30:09 +00004323- Issue #1481296: Make long(float('nan')) and int(float('nan')) raise
4324 ValueError consistently across platforms.
4325
Amaury Forgeot d'Arc39fd6722008-07-31 21:28:03 +00004326- Issue #3479: On platforms where sizeof(int) is smaller than sizeof(long)
4327 (64bit Unix, for example), unichr() would truncate its argument and return
4328 u'\x00' for unichr(2**32). Now it properly raises an OverflowError.
4329
Neal Norwitze7d8be82008-07-31 17:17:14 +00004330- Apply security patches from Apple.
4331
Amaury Forgeot d'Arc246daed2008-07-31 00:42:16 +00004332- Issue #2542: Now that issubclass() may call arbitrary code, ensure that
4333 PyErr_ExceptionMatches returns 0 when an exception occurs there.
4334
Antoine Pitrou92f82162008-07-25 22:22:08 +00004335- Issue #1819: function calls with several named parameters are now on
4336 average 35% faster (as measured by pybench).
4337
Amaury Forgeot d'Arce4921fe2008-07-21 22:00:38 +00004338- Issue #2378: An unexpected UnboundLocalError or NameError could appear when
4339 the python debugger steps into a class statement: the free variables (local
4340 variables defined in an outer scope) would be deleted from the outer scope.
4341
Gregory P. Smith0470bab2008-07-22 04:46:32 +00004342- Issue #2620: Overflow checking when allocating or reallocating memory
4343 was not always being done properly in some python types and extension
4344 modules. PyMem_MALLOC, PyMem_REALLOC, PyMem_NEW and PyMem_RESIZE have
4345 all been updated to perform better checks and places in the code that
4346 would previously leak memory on the error path when such an allocation
4347 failed have been fixed.
4348
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00004349Library
4350-------
4351
Hirokazu Yamamoto838c79f2008-08-20 13:14:07 +00004352- Issue #3612: Added some missing basic types in ctypes.wintypes.
4353
Benjamin Petersone977ad42008-08-20 01:42:01 +00004354- The methods ``is_in_tuple()``, ``is_vararg()``, and ``is_keywordarg()`` of
4355 symtable.Symbol have been deprecated for removal in 3.0 and the next release.
4356
Amaury Forgeot d'Arc351ffb82008-08-18 19:23:47 +00004357- Issue #2234: distutils failed for some versions of the cygwin compiler. The
4358 version reported by these tools does not necessarily follow the python
4359 version numbering scheme, so the module is less strict when parsing it.
4360
Nick Coghlanf70385a2008-08-18 12:42:46 +00004361- Issue #2235: Added Py3k warnings for types which will become unhashable
4362 under the stricter __hash__ inheritance rules in 3.0. Several types
4363 which did not meet the rules for hash invariants and were already
4364 unhashable in 3.0 have now been explicitly flagged as unhashable in
4365 2.6 as well (collections.Mapping, collections.Set, unittest.TestSuite,
4366 xml.dom.minidom.NamedNodeMap, numbers.Number, UserList.UserList)
4367
Brett Cannon88f801d2008-08-18 00:46:22 +00004368- Update __all__ for cookielib, csv, os, urllib2, and weakref to include things
4369 imported into the module but exposed as part of the module's API.
4370
Brett Cannon7b96f072008-08-18 00:41:11 +00004371- Remove an unneeded import of abc.ABCMeta from 'inspect'.
4372
Brett Cannon46225e72008-08-18 00:36:52 +00004373- Remove unneeded imports of 'sys' and 'warnings' from 'io'.
4374
Brett Cannon25c9d6a2008-08-17 22:10:11 +00004375- Remove unneeded imports of 'warnings' from shelve, filecmp, and dummy_thread.
4376
Hirokazu Yamamoto41a81eb2008-08-17 13:10:46 +00004377- Issue #3575: Incremental decoder's decode function now takes bytearray
4378 by using 's*' instead of 't#'.
4379
Mark Dickinson3e4caeb2009-02-21 20:27:01 +00004380- Issue #2222: Fixed reference leak when occurred os.rename()
Hirokazu Yamamoto7f30a682008-08-17 09:46:56 +00004381 fails unicode conversion on 2nd parameter. (windows only)
4382
Georg Brandl222e2082010-08-01 22:27:39 +00004383- Issue #2464: urllib2 now supports a malformation in the URL received
Facundo Batista94f243a2008-08-17 03:38:39 +00004384 in a redirect.
4385
Brett Cannonabe423e2008-08-16 21:47:07 +00004386- Silence the DeprecationWarning raised when importing mimetools in
Brett Cannon721b1452008-08-16 22:00:27 +00004387 BaseHTTPServer, cgi (and rfc822), httplib.
Brett Cannonabe423e2008-08-16 21:47:07 +00004388
Facundo Batistaeb90b782008-08-16 14:44:07 +00004389- Issue #2776: fixed small issue when handling an URL with double slash
4390 after a 302 response in the case of not going through a proxy.
4391
Antoine Pitroub90a8be2008-08-15 21:03:21 +00004392- Issue #2676: in the email package, content-type parsing was hanging on
4393 pathological input because of quadratic or exponential behaviour of a
4394 regular expression.
4395
Antoine Pitrou11ec65d2008-08-14 21:04:30 +00004396- Issue #3476: binary buffered reading through the new "io" library is now
4397 thread-safe.
4398
Brett Cannonbf3157b2008-08-14 05:00:03 +00004399- Silence the DeprecationWarning of rfc822 when it is imported by mimetools
4400 since mimetools itself is deprecated. Because modules are cached, all
4401 subsequent imports of rfc822 will not raise a visible DeprecationWarning.
4402
Antoine Pitrou9fcd4b32008-08-11 17:21:36 +00004403- Issue #3134: shutil referenced undefined WindowsError symbol.
4404
Robert Schuppenies14646332008-08-10 11:01:53 +00004405- Issue #1342811: Fix leak in Tkinter.Menu.delete. Commands associated to
4406 menu entries were not deleted.
4407
Brett Cannon83e81842008-08-09 23:30:55 +00004408- Copied the implementation of reduce() to _functools.reduce() to have a
4409 version that did not raise a DeprecationWarning under -3.
4410
Antoine Pitrou76b8bee2008-08-09 17:27:23 +00004411- Issue #3205: When iterating over a BZ2File fails allocating memory, raise
4412 a MemoryError rather than silently stop the iteration.
4413
Guido van Rossum59ce9012008-08-09 14:55:34 +00004414- Issue #3487: sre "bytecode" validator. Passing invalid "re-bytecode"
4415 to _sre.compile() will now be rejected. This should not affect anybody
4416 since the re.compile() function never generates invalid re-bytecode.
4417
Skip Montanaroa032bf42008-08-08 22:52:51 +00004418- Issue #3436: Make csv.DictReader's fieldnames attribute a property so that
4419 upon first access it can be automatically initialized from the csv file if
4420 it wasn't initialized during instantiation.
4421
Brett Cannon3aa2a492008-08-06 22:28:09 +00004422- Issue #2338: Create imp.reload() to help with transitioning to Python 3.0 as
4423 the reload() built-in has been removed.
4424
Brett Cannon7e30b672008-08-04 21:52:25 +00004425- Changed code in the following modules/packages to remove warnings raised
Brett Cannonc1b76e42008-08-09 23:06:16 +00004426 while running under the ``-3`` flag: aifc, asynchat, asyncore, bdb, bsddb,
Brett Cannon047e4a92008-08-17 04:16:04 +00004427 ConfigParser, cookielib, csv, difflib, distutils, DocXMLRPCServer, email,
4428 filecmp, fileinput, inspect, logging, modulefinder, pdb, pickle, profile,
4429 pstats, pydoc, re, rlcompleter, SimpleXMLRPCServer, shelve, socket,
4430 subprocess, sqlite3, tarfile, Tkinter, test.test_support, textwrap,
4431 threading, tokenize, traceback, urlparse, wsgiref, xml, xmlrpclib.
Brett Cannon7e30b672008-08-04 21:52:25 +00004432

4434 raised an AttributeError.
4435
Benjamin Peterson01a24322008-07-28 23:35:27 +00004436- Issue #2523: Fix quadratic behaviour when read()ing a binary file without
Antoine Pitroude781a42008-08-09 12:43:23 +00004437 asking for a specific length. This problem only affected files opened
4438 using the new "io" module, not the built-in open() function.
Benjamin Peterson01a24322008-07-28 23:35:27 +00004439
Mark Dickinsonfe84cce2008-07-27 06:39:07 +00004440- Issue #3449: Update decimal module to use most recent specification
4441 (v. 1.68) and tests (v. 2.58) from IBM.
4442
Georg Brandl222e2082010-08-01 22:27:39 +00004443- Issue #3437: Bug fix in robotparser parsing of Allow: lines.
Skip Montanarof9ac43f2008-07-27 00:50:41 +00004444

4447
Georg Brandlf9efabb2008-07-23 15:16:45 +00004448- Deprecate the "ast" parser function aliases.
4449
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00004450- Issue #3120: On 64-bit Windows the subprocess module was truncating handles.
4451
4452- Issue #3303: Fix a crash in locale.strcoll() when calling it with
4453 invalid arguments.
4454
4455- Issue #3302: Fix several crashes when calling locale's gettext functions
4456 with None arguments.
4457
4458- Issue #3389: Allow resolving dotted names for handlers in logging
4459 configuration files.
4460

4462
Antoine Pitrou5fdfa3e2008-07-25 19:42:26 +00004463- Issue #3394: zipfile.writestr sets external attributes when passed a
4464 file name rather than a ZipInfo instance, so files are extracted with
4465 mode 0600 rather than 000 under Unix.
4466
Gregory P. Smitha36f8fe2008-08-04 00:13:29 +00004467- Issue #1857: subprocess.Popen.poll gained an additional _deadstate keyword
4468 argument in python 2.5, this broke code that subclassed Popen to include its
4469 own poll method. Fixed my moving _deadstate to an _internal_poll method.

Nick Coghlan2a0c2b12008-08-04 12:47:17 +00004476Documentation
4477-------------
4478
Nick Coghlan6e8fef02008-08-18 13:14:22 +00004479- Issue #2235: the C API function PyObject_HashNotImplemented and its
4480 interaction with the tp_hash slot (added in 2.6b2) are now documented
4481
Nick Coghlan2a0c2b12008-08-04 12:47:17 +00004482- Issue #643841: The language reference now provides more detailed
4483 coverage of the lookup process for special methods. The disclaimers
4484 regarding lack of coverage of new-style classes have also been
4485 removed, since the coverage is now fairly reasonable.

Raymond Hettingere3ae6552008-06-20 04:18:15 +00004488What's New in Python 2.6 beta 2?
4489================================
4490
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00004491*Release date: 17-Jul-2008*
4492
Raymond Hettingere3ae6552008-06-20 04:18:15 +00004493Core and Builtins
4494-----------------
4495
Georg Brandl3e483f62008-07-16 22:57:41 +00004496- Issue #3156: Fix inconsistent behavior of the bytearray type: all
4497 its methods now allow for items objects that can be converted to
4498 an integer using operator.index().
4499
Mark Dickinson64b7e502008-07-16 09:40:03 +00004500- Issue #3360: Fix incorrect parsing of '020000000000.0', which
4501 produced a ValueError instead of giving the correct float.
4502
Eric Smitha5fa5a22008-07-16 00:11:49 +00004503- Issue #3083: Add alternate (#) formatting for bin, oct, hex output
4504 for str.format(). This adds the prefix 0b, 0o, or 0x, respectively.
4505
Mark Dickinson7103aa42008-07-15 19:08:33 +00004506- Issue #3008: the float type has a new instance method 'float.hex'
4507 and a new class method 'float.fromhex' to convert floating-point
4508 numbers to and from hexadecimal strings, respectively.
4509
Nick Coghlan6d6bd442008-07-15 15:40:22 +00004510- Issue #2235: __hash__ is once again inherited by default. To allow
4511 collections.Hashable to remain meaningful in the presence of the
4512 default hash implementation (object.__hash__), it is now possible
4513 to explicit block inheritance of hash by setting __hash__=None at
4514 the Python level, or tp_hash=PyObject_HashNotImplemented at the C
4515 level.
4516
Nick Coghlanb028f502008-07-13 14:52:36 +00004517- Issue #3221: Issue a RuntimeWarning instead of raising SystemError if
4518 the parent module cannot be found while performing an absolute import.
4519 This means that an incorrectly defined __package__ attribute will
4520 now only prevent relative imports in that module rather than causing
4521 all imports from that module to fail.
4522
Nick Coghlan14ff9942008-07-08 14:21:42 +00004523- Issue #2517: Allow unicode messages in Exceptions again by correctly
4524 bypassing the instance dictionary when looking up __unicode__ on
4525 new-style classes.
4526
Amaury Forgeot d'Arcbdd941f2008-07-01 20:38:04 +00004527- Issue #3242: Fix a crash inside the print statement, if sys.stdout is
4528 set to a custom object whose write() method happens to install
4529 another file in sys.stdout.
4530
Amaury Forgeot d'Arc1f40c8a2008-06-30 22:42:40 +00004531- Issue #3088: Corrected a race condition in classes derived from
4532 threading.local: the first member set by a thread could be saved in
4533 another thread's dictionary.
4534
Mark Dickinson1ec2fcd2008-06-20 14:53:43 +00004535- Issue #3004: Minor change to slice.indices(): the start and stop
4536 arguments are now treated identically, making the behaviour easier
4537 to describe and understand. For example, slice(None, -10,
4538 1).indices(9) now returns (0, 0, 1) instead of (0, -1, 1), and
4539 slice(None, 10, -1).indices(10) returns (9, 9, -1) instead of (9,
4540 10, -1).
4541
Georg Brandl278fc502008-07-19 12:46:12 +00004542- Issue #3219: Calling a function with repeated keyword arguments,

Georg Brandl3ee81df2008-05-17 18:14:43 +00005056- Issue #1631171: Re-implement the 'warnings' module in C (the
5057 original Python code has been kept as backup). This will allow for
5058 using the 'warning's machinery in such places as the parser where
5059 use of pure Python code is not possible. Both the ``showarning()``
5060 and ``formatwarning()`` gain an optional 'line' argument which is
5061 not called by default for backwards-compatibility reasons. Setting
5062 ``warnings.showwarning()`` to an implementation that lacks support
5063 for the ``line`` argument will raise a DeprecationWarning.

Georg Brandl3ee81df2008-05-17 18:14:43 +00005126- Issue #2550: The approach used by client/server code for obtaining
5127 ports to listen on in network-oriented tests has been refined in an
5128 effort to facilitate running multiple instances of the entire
5129 regression test suite in parallel without issue.
5130 test_support.bind_port() has been fixed such that it will always
5131 return a unique port -- which wasn't always the case with the
5132 previous implementation, especially if socket options had been set
5133 that affected address reuse (i.e. SO_REUSEADDR, SO_REUSEPORT). The
5134 new implementation of bind_port() will actually raise an exception
5135 if it is passed an AF_INET/SOCK_STREAM socket with either the
5136 SO_REUSEADDR or SO_REUSEPORT socket option set. Furthermore, if
5137 available, bind_port() will set the SO_EXCLUSIVEADDRUSE option on
5138 the socket it's been passed. This currently only applies to
5139 Windows. This option prevents any other sockets from binding to the
5140 host/port we've bound to, thus removing the possibility of the
5141 'non-deterministic' behaviour, as Microsoft puts it, that occurs
5142 when a second SOCK_STREAM socket binds and accepts to a host/port
5143 that's already been bound by another socket. The optional preferred
5144 port parameter to bind_port() has been removed. Under no
5145 circumstances should tests be hard coding ports!
5146
5147 test_support.find_unused_port() has also been introduced, which will
5148 pass a temporary socket object to bind_port() in order to obtain an
5149 unused port. The temporary socket object is then closed and
5150 deleted, and the port is returned. This method should only be used
5151 for obtaining an unused port in order to pass to an external program
5152 (i.e. the -accept [port] argument to openssl's s_server mode) or as
5153 a parameter to a server-oriented class that doesn't give you direct
5154 access to the underlying socket used.
5155
5156 Finally, test_support.HOST has been introduced, which should be used
5157 for the host argument of any relevant socket calls (i.e. bind and
5158 connect).
Trent Nelsone41b0062008-04-08 23:47:30 +00005159
5160 The following tests were updated to following the new conventions:
Georg Brandl3ee81df2008-05-17 18:14:43 +00005161 test_socket, test_smtplib, test_asyncore, test_ssl, test_httplib,
Trent Nelsone41b0062008-04-08 23:47:30 +00005162 test_poplib, test_ftplib, test_telnetlib, test_socketserver,
5163 test_asynchat and test_socket_ssl.
5164
Georg Brandl3ee81df2008-05-17 18:14:43 +00005165 It is now possible for multiple instances of the regression test
5166 suite to run in parallel without issue.

5371 libffi3.0.4 version, apart from some small changes to
Georg Brandl3ee81df2008-05-17 18:14:43 +00005372 Modules/_ctypes/libffi/configure.ac. On OS X, preconfigured libffi
5373 files are used. On all linux systems the --with-system-ffi
5374 configure option defaults to "yes".

Fred Drakea8ee94b2008-03-01 02:45:07 +00005435- Issue #2051: pyc and pyo files are no longer created with permission
Barry Warsaw52973612008-03-01 02:23:38 +00005436 644. The mode is now inherited from the py file.

Eric Smitha73fbe72008-02-23 03:09:44 +00005445- Added the future_builtins module, which contains hex() and oct().
5446 These are the PEP 3127 version of these functions, designed to be
5447 compatible with the hex() and oct() builtins from Python 3.0. They
5448 differ slightly in their output formats from the existing, unchanged
5449 Python 2.6 builtins. The expected usage of the future_builtins
5450 module is:
5451 from future_builtins import hex, oct
5452
Eric Smith7ef40bf2008-02-20 23:34:22 +00005453- Issue #1600: Modifed PyOS_ascii_formatd to use at most 2 digit
5454 exponents for exponents with absolute value < 100. Follows C99
5455 standard. This is a change on Windows, which would use 3 digits.
5456 Also, added 'n' to the formats that PyOS_ascii_formatd understands,
5457 so that any alterations it does to the resulting string will be
5458 available in stringlib/formatter.h (for float.__format__).
5459
Eric Smith5a3c1352008-02-19 13:21:56 +00005460- Implemented PEP 3101, Advanced String Formatting. This adds a new
5461 builtin format(); a format() method for str and unicode; a
5462 __format__() method to object, str, unicode, int, long, float, and
5463 datetime; the class string.Formatter; and the C API
5464 PyObject_Format().
5465
Georg Brandl3ee81df2008-05-17 18:14:43 +00005466- Fixed several potential crashes, all caused by specially crafted
5467 __del__ methods exploiting objects in temporarily inconsistent
5468 state.
Amaury Forgeot d'Arc632fad32008-02-16 20:55:24 +00005469
Vinay Sajipb7edfc42008-04-02 21:10:23 +00005470- Issue #2115: Important speedup in setting __slot__ attributes. Also
Georg Brandl3ee81df2008-05-17 18:14:43 +00005471 prevent a possible crash: an Abstract Base Class would try to access
5472 a slot on a registered virtual subclass.
Amaury Forgeot d'Arc60d6c7f2008-02-15 21:22:45 +00005473
Georg Brandl3ee81df2008-05-17 18:14:43 +00005474- Fixed repr() and str() of complex numbers with infinity or nan as
5475 real or imaginary part.

Georg Brandl3ee81df2008-05-17 18:14:43 +00005477- Clear all free lists during a gc.collect() of the highest generation
5478 in order to allow pymalloc to free more arenas. Python may give back
5479 memory to the OS earlier.
Christian Heimes3b718a72008-02-14 12:47:33 +00005480
Georg Brandl3ee81df2008-05-17 18:14:43 +00005481- Issue #2045: Fix an infinite recursion triggered when printing a
5482 subclass of collections.defaultdict, if its default_factory is set
5483 to a bound method.
Amaury Forgeot d'Arcb01aa432008-02-08 00:56:02 +00005484
Christian Heimesf75dbef2008-02-08 00:11:31 +00005485- Fixed a minor memory leak in dictobject.c. The content of the free
5486 list was not freed on interpreter shutdown.
5487
Georg Brandl21e99f42010-03-07 15:23:59 +00005488- Limit free list of method and built-in function objects to 256
Georg Brandl3ee81df2008-05-17 18:14:43 +00005489 entries each.
Christian Heimes6075a822008-02-06 12:44:34 +00005490
Georg Brandl3ee81df2008-05-17 18:14:43 +00005491- Patch #1953: Added ``sys._compact_freelists()`` and the C API
5492 functions ``PyInt_CompactFreeList`` and ``PyFloat_CompactFreeList``
Christian Heimes422051a2008-02-04 18:00:12 +00005493 to compact the internal free lists of pre-allocted ints and floats.
5494
Georg Brandl3ee81df2008-05-17 18:14:43 +00005495- Issue #1983: Fixed return type of fork(), fork1() and forkpty()
5496 calls. Python expected the return type int but the fork familie
5497 returns pi_t.
Christian Heimes951cc0f2008-01-31 23:08:23 +00005498
Georg Brandl3ee81df2008-05-17 18:14:43 +00005499- Issue #1678380: Fix a bug that identifies 0j and -0j when they
5500 appear in the same code unit.

Georg Brandl3ee81df2008-05-17 18:14:43 +00005511- Patch #1473257: generator objects gain a gi_code attribute. This is
5512 the same object as the func_code attribute of the function that
5513 produced the generator.
Georg Brandl0cdf9a32008-01-26 14:14:20 +00005514
Georg Brandl3ee81df2008-05-17 18:14:43 +00005515- Issue #1920: "while 0" statements were completely removed by the
5516 compiler, even in the presence of an "else" clause, which is
5517 supposed to be run when the condition is false. Now the compiler
5518 correctly emits bytecode for the "else" suite.
Amaury Forgeot d'Arc31eaafe2008-01-24 22:59:25 +00005519
Guido van Rossumeead05f2008-01-24 18:21:02 +00005520- A few crashers fixed: weakref_in_del.py (issue #1377858);
5521 loosing_dict_ref.py (issue #1303614, test67.py);
5522 borrowed_ref_[34].py (not in tracker).
5523
Vinay Sajipd7cf32e2008-01-24 12:43:33 +00005524- Issue #1069410: The "can't load dll" message box on Windows is
Christian Heimesb2302ba2008-01-23 17:15:06 +00005525 suppressed while an extension is loaded by calling SetErrorMode in
5526 dynload_win.c. The error is still reported properly.
5527
Georg Brandl3ee81df2008-05-17 18:14:43 +00005528- Issue #1915: Python compiles with --enable-unicode=no again. However
Christian Heimes082c9b02008-01-23 14:20:50 +00005529 several extension methods and modules do not work without unicode
5530 support.
5531
Georg Brandl26543b12008-01-21 18:36:51 +00005532- Issue #1882: when compiling code from a string, encoding cookies in the
5533 second line of code were not always recognized correctly.
5534
Georg Brandl14404b62008-01-19 19:27:05 +00005535- Issue #1679: "0x" was taken as a valid integer literal.
5536
Georg Brandl6caad7d2008-01-26 14:19:22 +00005537- Issue #1865: ``bytes`` as an alias for ``str`` and b"" as an alias "" were
Christian Heimes288e89a2008-01-18 18:24:07 +00005538 added.
5539
Christian Heimesc94e2b52008-01-14 04:13:37 +00005540- sys.float_info / PyFloat_GetInfo: The floating point information
5541 object was converted from a dict to a specialized structseq object.
5542
Georg Brandl3ee81df2008-05-17 18:14:43 +00005543- Patch #1816: Added sys.flags structseq. It exposes the status of
5544 most command line arguments and PYTHON* environment variables.
Christian Heimesf31b69f2008-01-14 03:42:48 +00005545
Georg Brandl3ee81df2008-05-17 18:14:43 +00005546- Objects/structseq.c: Implemented new structseq representation. The
5547 patch makes structseqs (e.g. the return value of os.stat) more
5548 readable.
Christian Heimes9c201962008-01-14 03:33:52 +00005549
Georg Brandl3ee81df2008-05-17 18:14:43 +00005550- Patch #1700288: added a type attribute cache that caches method

Georg Brandl3ee81df2008-05-17 18:14:43 +00005572 and INF. float("nan"), float("inf") and float("-inf") now work on
5573 every platform with IEEE 754 semantics.
Christian Heimes0a8143f2007-12-18 23:22:54 +00005574
Georg Brandl3ee81df2008-05-17 18:14:43 +00005575- Compiler now generates simpler and faster code for dictionary
5576 literals. The oparg for BUILD_MAP now indicates an estimated
5577 dictionary size. There is a new opcode, STORE_MAP, for adding
5578 entries to the dictionary.

Georg Brandl3ee81df2008-05-17 18:14:43 +00005607- Patch #1739468: Directories and zipfiles containing a __main__.py
5608 file can now be directly executed by passing their name to the
5609 interpreter. The directory/zipfile is automatically inserted as the
5610 first entry in sys.path.

Georg Brandl3ee81df2008-05-17 18:14:43 +00005612- Issue #1265: Fix a problem with sys.settrace, if the tracing
5613 function uses a generator expression when at the same time the
5614 executed code is closing a paused generator.
Amaury Forgeot d'Arc0d75f092007-11-13 21:54:28 +00005615
Raymond Hettinger1760c8a2007-11-08 02:52:43 +00005616- sets and frozensets now have an isdisjoint() method.

5621
Georg Brandl21e99f42010-03-07 15:23:59 +00005622- The enumerate() built-in function is no longer bounded to sequences
Georg Brandl3ee81df2008-05-17 18:14:43 +00005623 smaller than LONG_MAX. Formerly, it raised an OverflowError. Now,
5624 automatically shifts from ints to longs.
Raymond Hettinger8f669372007-10-03 21:18:11 +00005625
Georg Brandl3ee81df2008-05-17 18:14:43 +00005626- Issue #1686386: Tuple's tp_repr did not take into account the
5627 possibility of having a self-referential tuple, which is possible
5628 from C code. Nor did object's tp_str consider that a type's tp_str
5629 could do something that could lead to an inifinite recursion.
5630 Py_ReprEnter() and Py_EnterRecursiveCall(), respectively, fixed the
5631 issues.
Brett Cannon0b14f242007-09-30 19:45:10 +00005632
Georg Brandl3ee81df2008-05-17 18:14:43 +00005633- Issue #1164: It was possible to trigger deadlock when using the
5634 'print' statement to write to a file since the GIL was not released
5635 as needed. Now PyObject_Print() does the right thing along with
5636 various tp_print implementations of the built-in types and those in
5637 the collections module.
Brett Cannon01531592007-09-17 03:28:34 +00005638
Georg Brandl3ee81df2008-05-17 18:14:43 +00005639- Issue #1147: Exceptions were directly allowing string exceptions in

5641 allowed.

Brett Cannona0c05512007-09-10 21:38:27 +00005645
Brett Cannon1e534b52007-09-07 04:18:30 +00005646- Issue #1202533: Fix infinite recursion calls triggered by calls to
Georg Brandl3ee81df2008-05-17 18:14:43 +00005647 PyObject_Call() never calling back out to Python code to trigger
5648 recursion depth updates/checks. Required the creation of a static
5649 RuntimeError instance in case normalizing an exception put the
5650 recursion check value past its limit. Fixes crashers
5651 infinite_rec_(1|2|4|5).py.
Brett Cannon1e534b52007-09-07 04:18:30 +00005652

Neal Norwitz0ac60192007-05-27 04:08:54 +00005666- Add new attribute names for function objects. All the func_* become
Georg Brandl3ee81df2008-05-17 18:14:43 +00005667 __*__ attributes. (Some already existed, e.g., __doc__ and
5668 __name__.)
Neal Norwitz0ac60192007-05-27 04:08:54 +00005669
Neal Norwitz8b2bfbc2007-05-23 06:35:32 +00005670- Add -3 option to the interpreter to warn about features that are
5671 deprecated and will be changed/removed in Python 3.0.
5672
Georg Brandl2134e752007-05-21 20:34:16 +00005673- Patch #1686487: you can now pass any mapping after '**' in function
5674 calls.
5675
Collin Winter62903052007-05-18 23:11:24 +00005676- except clauses may now be spelled either "except E, target:" or
Georg Brandl3ee81df2008-05-17 18:14:43 +00005677 "except E as target:". This is to provide forwards compatibility
5678 with Python 3.0.
Collin Winter62903052007-05-18 23:11:24 +00005679
Brett Cannon229cee22007-05-05 01:34:02 +00005680- Deprecate BaseException.message as per PEP 352.

Vinay Sajip8549ce32007-05-06 17:53:37 +00005685- When __slots__ are set to a unicode string, make it work the same as
Neal Norwitzcbd9ee62007-04-14 05:25:50 +00005686 setting a plain string, ie don't expand to single letter identifiers.
5687
Raymond Hettinger13936692007-04-11 18:40:58 +00005688- Request #1191699: Slices can now be pickled.
5689
Raymond Hettinger4db5fe92007-04-12 04:10:00 +00005690- Request #1193128: str.translate() now allows a None argument for
5691 translations that only remove characters without re-mapping the
5692 remaining characters.
5693
Georg Brandl5cb76c12007-03-21 09:00:39 +00005694- Patch #1682205: a TypeError while unpacking an iterable is no longer

5698
Guido van Rossum143b5642007-03-23 04:58:42 +00005699- Bug #1683368: The object.__init__() and object.__new__() methods are
5700 now stricter in rejecting excess arguments. The only time when
5701 either allows excess arguments is when it is not overridden and the
5702 other one is. For backwards compatibility, when both are
5703 overridden, it is a deprecation warning (for now; maybe a Py3k
Guido van Rossum234b1ff2007-03-23 19:39:01 +00005704 warning later). Also, type.__init__() insists on the same signature
5705 as supported by type.__new__().
Guido van Rossum143b5642007-03-23 04:58:42 +00005706
Georg Brandl3ee81df2008-05-17 18:14:43 +00005707- Patch #1675423: PyComplex_AsCComplex() now tries to convert an
5708 object to complex using its __complex__() method before falling back
5709 to the __float__() method. Therefore, the functions in the cmath
5710 module now can operate on objects that define a __complex__()
5711 method.
Georg Brandl2b869942007-03-17 16:08:45 +00005712
Georg Brandl3ee81df2008-05-17 18:14:43 +00005713- Patch #1623563: allow __class__ assignment for classes with
5714 __slots__. The old and the new class are still required to have the
5715 same slot names.

5721 ``object.__reduce_ex__()`` is called with an object that is faking
5722 its type.

5728
Georg Brandl7b9c5552007-03-12 14:30:05 +00005729- Bug #1678647: write a newline after printing an exception in any
5730 case, even when converting the value to a string failed.
5731
Georg Brandl871f1bc2007-03-12 13:17:36 +00005732- The dir() function has been extended to call the __dir__() method on
Georg Brandl3ee81df2008-05-17 18:14:43 +00005733 its argument, if it exists. If not, it will work like before. This
5734 allows customizing the output of dir() in the presence of a
5735 __getattr__().

Georg Brandl3ee81df2008-05-17 18:14:43 +00005743- Patch #1491866: change the complex() constructor to allow
5744 parthensized forms. This means complex(repr(x)) now works instead of
5745 raising a ValueError.
Collin Wintere38051d2007-03-09 20:33:07 +00005746
Georg Brandlaa2321b2007-03-07 00:40:28 +00005747- Patch #703779: unset __file__ in __main__ after running a file. This
Georg Brandl3ee81df2008-05-17 18:14:43 +00005748 makes the filenames the warning module prints much more sensible
5749 when a PYTHONSTARTUP file is used.

Georg Brandl0fca97a2007-03-05 22:28:08 +00005762- Patch #1674228: when assigning a slice (old-style), check for the
5763 sq_ass_slice instead of the sq_slice slot.
5764
Georg Brandl3ee81df2008-05-17 18:14:43 +00005765- When printing an unraisable error, don't print exceptions. before
5766 the name. This duplicates the behavior whening normally printing
5767 exceptions.

6333
Georg Brandl92a6bae2007-03-13 17:43:32 +00006334- Patch #1603688: ConfigParser.SafeConfigParser now checks values that
Georg Brandl3ee81df2008-05-17 18:14:43 +00006335 are set for invalid interpolation sequences that would lead to

6392 TestCase and TestSuite subclasses (not instances) are no longer
6393 accepted in TestSuite.addTest(). This should cause no
6394 incompatibility since it never made sense with ordinary subclasses
6395 -- the failure just occurred later, with a more cumbersome
6396 exception.

Georg Brandl3ee81df2008-05-17 18:14:43 +00006677- Issue #829951: In the smtplib module, SMTP.starttls() now complies
6678 with RFC 3207 and forgets any knowledge obtained from the server not
6679 obtained from the TLS negotiation itself. Patch contributed by Bill
6680 Fenner.
Gregory P. Smith2b3ba582008-01-17 08:03:17 +00006681
Georg Brandl3ee81df2008-05-17 18:14:43 +00006682- Issue #1339: The smtplib.SMTP class has been refactored a bit such
Gregory P. Smithbde4ae42008-01-17 08:35:49 +00006683 that the SMTP.starttls() caller no longer needs to call ehlo()
6684 beforehand. SMTP.starttls() now raises an exception of the server
Georg Brandl3ee81df2008-05-17 18:14:43 +00006685 does not claim to support starttls. Adds the
6686 SMTP.ehlo_or_helo_if_needed() method. Patch contributed by Bill

Georg Brandl3ee81df2008-05-17 18:14:43 +00006741- itertools.chain() now has an alternate constructor,

6767 complex, tuple, list, dict, set, and frozenset. Formerly, it would
6768 silently miscode subclasses of those types. Now, it raises a
6769 ValueError instead.
Raymond Hettinger12e94202007-11-07 01:13:09 +00006770

Georg Brandl3ee81df2008-05-17 18:14:43 +00006785 time so that opening a database previously created with the DB_DUP
6786 or DB_DUPSORT flag set will keep the proper behavior on subsequent
6787 opens. Specifically: dictionary assignment to a DB object will
6788 replace all values for a given key when the database allows
6789 duplicate values. DB users should use DB.put(k, v) when they want
6790 to store duplicates; not DB[k] = v.
Gregory P. Smithec10a4a2007-11-05 02:32:26 +00006791

6797 characters with ASCII value less than 32. Also, it correctly quotes
6798 dots only if they occur on a single line, as opposed to the previous
6799 behavior of quoting dots if they are the second character of any
6800 line.
Georg Brandl4aef7272007-03-13 22:49:43 +00006801

Georg Brandl3ee81df2008-05-17 18:14:43 +00007070 periodic threadstate and signal checking in tight loops. By
7071 default, this option is turned-off. It should only be enabled in
7072 debugged, performance critical applications.

Christian Heimes5b970ad2008-02-06 13:33:44 +00007129
Georg Brandl3ee81df2008-05-17 18:14:43 +00007130- ``PySet_Add()`` can now modify a newly created frozenset. Similarly
7131 to ``PyTuple_SetItem``, it can be used to populate a brand new

7144
Georg Brandl3ee81df2008-05-17 18:14:43 +00007145- Issue #1521: On 64bit platforms, using PyArgs_ParseTuple with the t#
7146 of w# format code incorrectly truncated the length to an int, even
7147 when PY_SSIZE_T_CLEAN is set. The str.decode method used to return
7148 incorrect results with huge strings.
Georg Brandl6caad7d2008-01-26 14:19:22 +00007149
Georg Brandl3ee81df2008-05-17 18:14:43 +00007150- Issue #1629: Renamed Py_Size, Py_Type and Py_Refcnt to Py_SIZE,

7172 outside of pystate.c and should not be necessary.
7173
Georg Brandl3ee81df2008-05-17 18:14:43 +00007174- ``PyImport_Import`` and ``PyImport_ImportModule`` now always do
7175 absolute imports. In earlier versions they might have used relative
7176 imports under some conditions.

Georg Brandl3ee81df2008-05-17 18:14:43 +00007178- Added case insensitive comparison methods ``PyOS_stricmp(char*,
7179 char*)`` and ``PyOS_strnicmp(char*, char*, Py_ssize_t)``.
Christian Heimes000a0742008-01-03 22:16:32 +00007180
Georg Brandl3ee81df2008-05-17 18:14:43 +00007181- Bug #1542693: remove semi-colon at end of PyImport_ImportModuleEx

7191 builds.
Christian Heimes95d64472008-02-09 19:55:22 +00007192

Georg Brandl3ee81df2008-05-17 18:14:43 +00007206- Removed the macfs module. It had been deprecated since Python 2.5.
7207 This lead to the deprecation of macostools.touched() as it relied
7208 solely on macfs and was a no-op under OS X.
