185 handles non-blocking readinto() returning None correctly.

188 SSLSocket.sendto() to match the corresponding socket methods. Also,
189 fix various SSLSocket methods to raise socket.error rather than an
190 unhelpful TypeError when called on an unconnected socket. Original patch
191 by Andrew Bennetts.

202 This prevents user-created self-referencing ordered dictionaries from
203 becoming permanently uncollectable GC garbage. The downside is that
204 removing __del__ means that the internal doubly-linked list has to wait for
205 GC collection rather than freeing memory immediately when the refcnt drops
206 to zero.
207
Raymond Hettingerffd2a422010-09-10 10:47:22 +0000208- Issue #9816: random.Random.jumpahead(n) did not produce a sufficiently

Raymond Hettingerffd2a422010-09-10 10:47:22 +0000210 value.
211
Antoine Pitrouc818ed42010-09-07 21:40:25 +0000212- Issue #9792: In case of connection failure, socket.create_connection()
213 would swallow the exception and raise a new one, making it impossible
214 to fetch the original errno, or to filter timeout errors. Now the
215 original error is re-raised.
216
Antoine Pitrouf4f61712010-09-07 16:34:47 +0000217- Issue #9758: When fcntl.ioctl() was called with mutable_flag set to True,
218 and the passed buffer was exactly 1024 bytes long, the buffer wouldn't
219 be updated back after the system call. Original patch by Brian Brazil.
220
Antoine Pitroudca9de92010-09-04 17:52:26 +0000221- Issue #1100562: Fix deep-copying of objects derived from the list and
222 dict types. Patch by Michele Orrù and Björn Lindqvist.
223

225 ConfigParser.write.
226
Daniel Stutzbach66c981b2010-08-31 20:29:39 +0000227- Issue #808164: Fixed socket.close to avoid references to globals, to
228 avoid issues when socket.close is called from a __del__ method.
229
Terry Reedyd2d2ae92010-11-11 23:22:19 +0000230- Issue #2986: difflib.SequenceMatcher gets a new parameter, autojunk, which

232 heuristic. Patch by Terry Reedy and Eli Bendersky
233
Senthil Kumaran7e8fd5e2010-08-26 06:20:13 +0000234- Issue #8797: urllib2 does a retry for Basic Authentication failure instead of
235 falling into recursion.
236
R. David Murray7c4bf552010-08-25 01:45:57 +0000237- Issue #1194222: email.utils.parsedate now returns RFC2822 compliant four
238 character years even if the message contains RFC822 two character years.
239
Daniel Stutzbach91287322010-08-24 21:09:30 +0000240- Issue #8750: Fixed MutableSet's methods to correctly handle
241 reflexive operations, namely x -= x and x ^= x.
242
Victor Stinnercaafd772010-09-08 10:51:01 +0000243- Issue #9129: smtpd.py is vulnerable to DoS attacks deriving from missing

253
Antoine Pitrou3ebaed62010-08-21 19:17:25 +0000254- Issue #9617: Signals received during a low-level write operation aren't
255 ignored by the buffered IO layer anymore.
256
Benjamin Peterson52c36052010-08-21 03:03:22 +0000257- Issue #2521: Use weakrefs on for caching in the abc module, so that classes
258 are not held onto after they are deleted elsewhere.
259
Raymond Hettingera54b2da2010-08-17 19:03:06 +0000260- Issue #9626: the view methods for collections.OrderedDict() were returning
261 the unordered versions inherited from dict. Those methods are now
262 overridden to provide ordered views.
263
Éric Araujo0389ae62010-08-14 03:07:46 +0000264- Issue #8688: MANIFEST files created by distutils now include a magic

Antoine Pitroue1436d12010-08-12 15:25:51 +0000268- Issue #7467: when reading a file from a ZIP archive, its CRC is checked

Antoine Pitroucb4f47c2010-08-11 13:40:17 +0000272- Issue #9550: a BufferedReader could issue an additional read when the
273 original read request had been satisfied, which could block indefinitely
274 when the underlying raw IO channel was e.g. a socket. Report and original
275 patch by Jason V. Miller.
276
Fred Drake0a1fa0e2010-08-10 13:09:54 +0000277- Issue #9551: Don't raise TypeError when setting the value to None for

279
Antoine Pitrou8cdede42010-08-10 00:04:13 +0000280- Issue #6915: Under Windows, os.listdir() didn't release the Global

663
Ezio Melottiab2eb0e2010-06-05 19:21:32 +0000664- Issue #8271: during the decoding of an invalid UTF-8 byte sequence, only the
665 start byte and the continuation byte(s) are now considered invalid, instead
666 of the number of bytes specified by the start byte.
667 E.g.: '\xf1\x80AB'.decode('utf-8', 'replace') now returns u'\ufffdAB' and
668 replaces with U+FFFD only the start byte ('\xf1') and the continuation byte
669 ('\x80') even if '\xf1' is the start byte of a 4-bytes sequence.
670 Previous versions returned a single u'\ufffd'.
671
Mark Dickinson23f0d6b2010-06-05 11:52:24 +0000672- Issue #8627: Remove bogus "Overriding __cmp__ blocks inheritance of

674 arises from the "Overriding __eq__ blocks inheritance ..." warning
675 when turned into an exception: in this case the exception simply
676 gets ignored.

Mark Dickinson4ca7c3c2010-05-30 13:18:10 +0000678- Issue #8748: Fix two issues with comparisons between complex and integer
679 objects. (1) The comparison could incorrectly return True in some cases
680 (2**53+1 == complex(2**53) == 2**53), breaking transivity of equality.
681 (2) The comparison raised an OverflowError for large integers, leading
682 to unpredictable exceptions when combining integers and complex objects
683 in sets or dicts.
684
Mark Dickinson81336372010-05-30 12:12:25 +0000685- Issue #5211: Implicit coercion for the complex type is now completely
686 removed. (Coercion for arithmetic operations was already removed in 2.7
687 alpha 4, but coercion for rich comparisons was accidentally left in.)
688
Victor Stinnerc49dfcc2010-05-25 22:30:32 +0000689- Issue #3798: Write sys.exit() message to sys.stderr to use stderr encoding

1066 with a non-empty format string. This is an effort to future-proof user
1067 code. If a derived class does not currently implement __format__ but later
1068 adds its own __format__, it would most likely break user code that had
1069 supplied a format string. This will be changed to a DeprecationWaring in
1070 Python 3.3 and it will be an error in Python 3.4.

Barry Warsawf7f2d6f2010-03-31 21:07:16 +00001130- Issue #8233: When run as a script, py_compile.py optionally takes a single
Georg Brandlfee0f442010-05-22 21:26:21 +00001131 argument `-` which tells it to read files to compile from stdin. Each line is
1132 read on demand and the named file is compiled immediately. (Original patch by
1133 Piotr Ożarowski).

Georg Brandlba83f822010-03-14 09:50:54 +00001503- Issue #7561: Operations on empty bytearrays (such as ``int(bytearray())``)
1504 could crash in many places because of the ``PyByteArray_AS_STRING()`` macro
1505 returning NULL. The macro now returns a statically allocated empty string
1506 instead.

1516 strings,
1517 (2) a crash in dtoa.c that occurred in debug builds when parsing certain long
1518 numeric strings corresponding to subnormal values,
1519 (3) a memory leak for some values large enough to cause overflow, and
1520 (4) a number of flaws that could lead to incorrectly rounded results.

Antoine Pitroud840e512010-02-04 20:20:18 +00001551- Issue #4772: Raise a ValueError when an unknown Bluetooth protocol is
Georg Brandlba83f822010-03-14 09:50:54 +00001552 specified, rather than fall through to AF_PACKET (in the ``socket`` module).
Antoine Pitroud840e512010-02-04 20:20:18 +00001553 Also, raise ValueError rather than TypeError when an unknown TIPC address
1554 type is specified. Patch by Brian Curtin.

Antoine Pitrouf3fa0742010-01-31 22:26:04 +00001558- Issue #6939: Fix file I/O objects in the `io` module to keep the original
Georg Brandlba83f822010-03-14 09:50:54 +00001559 file position when calling `truncate()`. It would previously change the file
1560 position to the given argument, which goes against the tradition of
Antoine Pitrouf3fa0742010-01-31 22:26:04 +00001561 ftruncate() and other truncation APIs. Patch by Pascal Chambon.
1562

1564 class used to represent files stored inside an archive. The new
1565 implementation is significantly faster and can be wrapped in a
1566 ``io.BufferedReader`` object for more speedups. It also solves an issue
1567 where interleaved calls to ``read()`` and ``readline()`` give wrong results.
1568 Patch by Nir Aides.

Georg Brandlba83f822010-03-14 09:50:54 +00001578- Issue #7748: Since unicode values are supported for some metadata options in
1579 Distutils, the DistributionMetadata get_* methods will now return an utf-8
1580 encoded string for them. This ensures that the upload and register commands
1581 send the correct values to PyPI without any error.

1656-----------------
1657
Georg Brandlba83f822010-03-14 09:50:54 +00001658- The ``__complex__()`` method is now looked up on the class of instances to
1659 make it consistent with other special methods.
Benjamin Petersonecdae192010-01-04 00:43:01 +00001660
Antoine Pitrou5b7139a2010-01-02 21:12:58 +00001661- Issue #7462: Implement the stringlib fast search algorithm for the `rfind`,
1662 `rindex`, `rsplit` and `rpartition` methods. Patch by Florent Xicluna.
1663
Mark Dickinson1b34d252010-01-01 17:27:30 +00001664- Issue #5080: A number of functions and methods previously produced a
Georg Brandlba83f822010-03-14 09:50:54 +00001665 DeprecationWarning when passed a float argument where an integer was expected.
1666 These functions and methods now raise TypeError instead. The majority of the
1667 effects of this change are in the extension modules, but some core functions
1668 and methods are affected: notably the 'chr', 'range' and 'xrange' builtins,
1669 and many unicode/str methods.

1681
Georg Brandlba83f822010-03-14 09:50:54 +00001682- Issue #1811: Improve accuracy and cross-platform consistency for true division
1683 of integers: the result of a/b is now correctly rounded for ints a and b (at
1684 least on IEEE 754 platforms), and in particular does not depend on the
1685 internal representation of a long.

1693
Georg Brandlba83f822010-03-14 09:50:54 +00001694 These executables now work properly with the arch(1) command: ``arch -ppc
1695 python`` will start a universal binary version of python in PPC mode (unlike

Georg Brandlba83f822010-03-14 09:50:54 +00001852- Issue #7117: ``repr(x)`` for a float x returns a result based on the shortest
1853 decimal string that's guaranteed to round back to x under correct rounding
1854 (with round-half-to-even rounding mode). Previously it gave a string based on
1855 rounding x to 17 decimal digits. repr(x) for a complex number behaves
1856 similarly. On platforms where the correctly-rounded strtod and dtoa code is
1857 not supported (see below), repr is unchanged.

Georg Brandlba83f822010-03-14 09:50:54 +00001859- Issue #7117: On almost all platforms: float-to-string and string-to-float
1860 conversions within Python are now correctly rounded. Places these conversions
1861 occur include: str for floats and complex numbers; the float and complex
1862 constructors; old-style and new-style numeric formatting; serialization and
1863 deserialization of floats and complex numbers using marshal, pickle and json;
1864 parsing of float and imaginary literals in Python code; Decimal-to-float
1865 conversion.
Mark Dickinsonb678de82009-11-19 18:41:49 +00001866
Georg Brandlba83f822010-03-14 09:50:54 +00001867 The conversions use a Python-adapted version of David Gay's well-known dtoa.c,
1868 providing correctly-rounded strtod and dtoa C functions. This code is
1869 supported on Windows, and on Unix-like platforms using gcc, icc or suncc as
1870 the C compiler. There may be a small number of platforms on which correct
1871 operation of this code cannot be guaranteed, so the code is not used: notably,
1872 this applies to platforms where the C double format is not IEEE 754 binary64,
1873 and to platforms on x86 hardware where the x87 FPU is set to 64-bit precision
1874 and Python's configure script is unable to determine how to change the FPU
1875 precision. On these platforms conversions use the platform strtod and dtoa,
1876 as before.

Georg Brandlba83f822010-03-14 09:50:54 +00001878- Issue #7117: Backport round implementation from Python 3.x. ``round()`` now
1879 uses the correctly-rounded string <-> float conversions described above (when
1880 available), and so produces correctly rounded results that will display nicely
1881 under the float repr. There are two related small changes: (1) round now
1882 accepts any class with an ``__index__()`` method for its second argument (but
1883 no longer accepts floats for the second argument), and (2) an excessively
1884 large second integer argument (e.g., ``round(1.234, 10**100)``) no longer
1885 raises an exception.

Georg Brandlba83f822010-03-14 09:50:54 +00003450- Issue #6561: '\d' in a regex now matches only characters with Unicode category
3451 'Nd' (Number, Decimal Digit). Previously it also matched characters with
3452 category 'No'.
Mark Dickinsonfe67bd92009-07-28 20:35:03 +00003453
Georg Brandlba83f822010-03-14 09:50:54 +00003454- Issue #1523: Remove deprecated overflow wrapping for struct.pack with an
3455 integer format code ('bBhHiIlLqQ'). Packing an out-of-range integer now
3456 consistently raises struct.error.
Mark Dickinson5fd3af22009-07-07 15:08:28 +00003457
Georg Brandlba83f822010-03-14 09:50:54 +00003458- Issues #1530559, #1741130: Fix various struct.pack inconsistencies for the

3460 '<', '>'.
Mark Dickinson463dc4b2009-07-05 10:01:24 +00003461
Georg Brandlba83f822010-03-14 09:50:54 +00003462 - Packing a float now always gives a Deprecation Warning. Previously it
3463 only warned for 'I', 'L', '*B', '*H', '*I', '*L'.
Mark Dickinson463dc4b2009-07-05 10:01:24 +00003464
Georg Brandlba83f822010-03-14 09:50:54 +00003465 - If x is not an int, long or float, then packing x will always result in
3466 struct.error. Previously an x with an __int__ method could be packed by
3467 'b', 'B', 'h', 'H', 'i', 'l', '*b', '*h' ,'*i', '*l', and an x with a
3468 __long__ method could be packed by 'q', 'Q', '*q', '*Q'; for x with
3469 neither __int__ nor __long__, TypeError used to be raised (with a
3470 confusing error message) for 'I', 'L', '*B', '*H', '*I', '*L', and
3471 struct.error in other cases.
Mark Dickinson463dc4b2009-07-05 10:01:24 +00003472
Georg Brandlba83f822010-03-14 09:50:54 +00003473 Note: as of Python 2.7 beta 1, the above is out of date. In 2.7 beta 1, any
3474 argument with an __int__ method can be packed, but use of this feature
3475 triggers a DeprecationWarning.

3483 supporting objects as input no matter how it was compiled (built in
Gregory P. Smithfe32d302010-01-02 22:42:50 +00003484 implementations or external openssl library). NOTE: Undone in 2.7a2.

Georg Brandlba83f822010-03-14 09:50:54 +00003508- Issue #7431: Use TESTFN in test_linecache instead of trying to create a file
3509 in the Lib/test directory, which might be read-only for the user running the
3510 tests.
R. David Murray820b0ea2009-12-03 23:57:59 +00003511
Georg Brandlba83f822010-03-14 09:50:54 +00003512- Issue #7324: Add a sanity check to regrtest argument parsing to catch the case
3513 of an option with no handler.
R. David Murrayda826892009-11-15 00:04:32 +00003514
Georg Brandlba83f822010-03-14 09:50:54 +00003515- Issue #7312: Add a -F flag to run the selected tests in a loop until a test
3516 fails. Can be combined with -j.
R. David Murray7f7eea62009-11-14 15:18:22 +00003517
Antoine Pitrou310c9fe2009-11-11 20:55:07 +00003518- Issue #7295: Do not use a hardcoded file name in test_tarfile.

Antoine Pitrouc98efe02009-11-06 22:34:35 +00003520- Issue #7270: Add some dedicated unit tests for multi-thread synchronization
3521 primitives such as Lock, RLock, Condition, Event and Semaphore.
3522
Antoine Pitrou59c44f32009-10-30 17:07:08 +00003523- Issue #7222: Make thread "reaping" more reliable so that reference
Georg Brandlba83f822010-03-14 09:50:54 +00003524 leak-chasing test runs give sensible results. The previous method of reaping
3525 threads could return successfully while some Thread objects were still
3526 referenced. This also introduces a new private function: ``thread._count()``.
Antoine Pitrou59c44f32009-10-30 17:07:08 +00003527
Georg Brandlba83f822010-03-14 09:50:54 +00003528- Issue #7151: Fixed regrtest -j so that output to stderr from a test no longer
3529 runs the risk of causing the worker thread to fail.
R. David Murray282396f2009-10-18 21:12:37 +00003530
Antoine Pitrou58d2f262009-10-10 20:52:11 +00003531- Issue #7055: test___all__ now greedily detects all modules which have an
3532 __all__ attribute, rather than using a hardcoded and incomplete list.
3533
R. David Murray14dcd432009-10-14 13:58:07 +00003534- Issue #7058: Added save/restore for things like sys.argv and cwd to
3535 runtest_inner in regrtest, with warnings if the called test modifies them,
3536 and a new section in the summary report at the end.
R. David Murrayabe3d3e2009-10-05 17:03:09 +00003537
Mark Dickinson245d9152009-10-04 18:38:39 +00003538- Issue #7042: Fix test_signal (test_itimer_virtual) failure on OS X 10.6.

3541 off the trailing 0 in the version number.
3542
Guilherme Polo7f146ab2009-06-21 17:22:50 +00003543- Issue #5450: Moved tests involving loading tk from Lib/test/test_tcl to
3544 Lib/lib-tk/test/test_tkinter/test_loadtk. With this, these tests demonstrate
Georg Brandlba83f822010-03-14 09:50:54 +00003545 the same behaviour as test_ttkguionly (and now also test_tk) which is to skip
3546 the tests if DISPLAY is defined but can't be used.
Guilherme Polo7f146ab2009-06-21 17:22:50 +00003547
Antoine Pitrou4698d992009-05-31 14:20:14 +00003548- Issue #6152: New option '-j'/'--multiprocess' for regrtest allows running
3549 regression tests in parallel, shortening the total runtime.
3550
Georg Brandlba83f822010-03-14 09:50:54 +00003551- Issue #5354: New test support function import_fresh_module() makes it easy to
3552 import both normal and optimised versions of modules. test_heapq and
3553 test_warnings have been adjusted to use it, tests for other modules with both
3554 C and Python implementations in the stdlib can be adjusted to use it over
3555 time.

3562
Georg Brandlba83f822010-03-14 09:50:54 +00003563- regrtest no longer treats ImportError as equivalent to SkipTest. Imports that
3564 should cause a test to be skipped are now done using import_module from test
3565 support, which does the conversion.
R. David Murray41448c52009-03-31 19:57:24 +00003566
Guilherme Polob1a98de2009-01-28 20:03:26 +00003567- Issue #5083: New 'gui' resource for regrtest.

Amaury Forgeot d'Arc05e34492008-09-10 22:04:45 +00003668- Issue #3743: In a few places, PY_FORMAT_SIZE_T was incorrectly used with
3669 PyString_FromFormat or PyErr_Format to display size_t values. The macro
3670 PY_FORMAT_SIZE_T is designed to select the correct format for the OS
3671 ``printf`` function, whereas PyString_FromFormat has an independent
3672 implementation and uses "%zd" on all platforms for size_t values.
3673 This makes a difference on win64, where ``printf`` needs "%Id" to display
3674 64bit values.

Benjamin Peterson97179b02008-09-09 20:55:01 +00003676- Issue #3634: _weakref.ref(Exception).__init__() gave invalid return value on

3688
Antoine Pitroud4ae97b2008-08-29 18:39:48 +00003689- Issue #3668: Fix a memory leak with the "s*" argument parser in
Vinay Sajip35e3b032008-09-01 14:33:59 +00003690 PyArg_ParseTuple and friends, which occurred when the argument for "s*"
Antoine Pitroud4ae97b2008-08-29 18:39:48 +00003691 was correctly parsed but parsing of subsequent arguments failed.
3692
Vinay Sajip35e3b032008-09-01 14:33:59 +00003693- Issue #2534: speed up isinstance() and issubclass() by 50-70%, so as to
Antoine Pitrou0668c622008-08-26 22:42:08 +00003694 match Python 2.5 speed despite the __instancecheck__ / __subclasscheck__
3695 mechanism. In the process, fix a bug where isinstance() and issubclass(),
3696 when given a tuple of classes as second argument, were looking up
3697 __instancecheck__ / __subclasscheck__ on the tuple rather than on each
3698 type object.
3699

3715 library targets in the Makefile.
3716
Gregory P. Smith980b99b2008-09-07 05:15:18 +00003717- Issue #1204: The configure script now tests for additional libraries
3718 that may be required when linking against readline. This fixes issues
3719 with x86_64 builds on some platforms (a few Linux flavors and OpenBSD).

Brett Cannon1eaf0742008-09-02 01:25:16 +00003769 warnings.catch_warnings() along with some API cleanup. Expanding the tests
3770 for catch_warnings() also led to an improvement in the raising of a
3771 DeprecationWarning related to warnings.warn_explicit().
3772

3795
Amaury Forgeot d'Arc293924b2008-09-02 23:19:56 +00003796- Issue #2975: When compiling several extension modules with Visual Studio 2008
3797 from the same python interpreter, some environment variables would grow
3798 without limit.
3799
Benjamin Peterson37346b22008-08-23 20:27:43 +00003800- Issue #3643: Added a few more checks to _testcapi to prevent segfaults by

Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00003837What's New in Python 2.6 beta 3?
3838================================
3839
Barry Warsaw07a4a382008-08-21 01:15:08 +00003840*Release date: 20-Aug-2008*
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00003841
3842Core and Builtins
3843-----------------
3844
Guido van Rossumf8402962008-08-20 15:01:50 +00003845- Issue #1878: Remove Py_TPFLAGS_HAVE_VERSION_TAG from
3846 Py_TPFLAGS_DEFAULT when not building the core. This means 3rd party
3847 extensions do not automatically benefit from the class attribute
3848 cache; they will have to explicitly add Py_TPFLAGS_HAVE_VERSION_TAG
3849 to their tp_flags field if they care. This is a backwards
3850 compatibility feature; in 3.0, all types will use the cache by
3851 default.
3852
Benjamin Petersonf647dc12008-08-20 01:27:30 +00003853- Keyword arguments can now follow starred arguments. (``f(a, *args,
3854 keyword=23)`` is now valid syntax.)
3855
Thomas Heller0ad5ae02008-08-19 19:25:04 +00003856- ctypes function pointers that are COM methods have a boolean True
3857 value again.
3858
Martin v. Löwisf91d46a2008-08-12 14:49:50 +00003859- Issue #3139: Make buffer-interface thread-safe wrt. PyArg_ParseTuple,
3860 by denying s# to parse objects that have a releasebuffer procedure,
3861 and introducing s*.
3862
Georg Brandl1e13ea92008-08-11 09:07:59 +00003863- Issue #3537: Fix an assertion failure when an empty but presized dict
3864 object was stored in the freelist.
3865
Mark Dickinsonb6467572008-08-04 21:30:09 +00003866- Issue #1481296: Make long(float('nan')) and int(float('nan')) raise
3867 ValueError consistently across platforms.
3868
Amaury Forgeot d'Arc39fd6722008-07-31 21:28:03 +00003869- Issue #3479: On platforms where sizeof(int) is smaller than sizeof(long)
3870 (64bit Unix, for example), unichr() would truncate its argument and return
3871 u'\x00' for unichr(2**32). Now it properly raises an OverflowError.
3872
Neal Norwitze7d8be82008-07-31 17:17:14 +00003873- Apply security patches from Apple.
3874
Amaury Forgeot d'Arc246daed2008-07-31 00:42:16 +00003875- Issue #2542: Now that issubclass() may call arbitrary code, ensure that
3876 PyErr_ExceptionMatches returns 0 when an exception occurs there.
3877
Antoine Pitrou92f82162008-07-25 22:22:08 +00003878- Issue #1819: function calls with several named parameters are now on
3879 average 35% faster (as measured by pybench).
3880
Amaury Forgeot d'Arce4921fe2008-07-21 22:00:38 +00003881- Issue #2378: An unexpected UnboundLocalError or NameError could appear when
3882 the python debugger steps into a class statement: the free variables (local
3883 variables defined in an outer scope) would be deleted from the outer scope.
3884
Gregory P. Smith0470bab2008-07-22 04:46:32 +00003885- Issue #2620: Overflow checking when allocating or reallocating memory
3886 was not always being done properly in some python types and extension
3887 modules. PyMem_MALLOC, PyMem_REALLOC, PyMem_NEW and PyMem_RESIZE have
3888 all been updated to perform better checks and places in the code that
3889 would previously leak memory on the error path when such an allocation
3890 failed have been fixed.

3893-------
3894
Hirokazu Yamamoto838c79f2008-08-20 13:14:07 +00003895- Issue #3612: Added some missing basic types in ctypes.wintypes.
3896
Benjamin Petersone977ad42008-08-20 01:42:01 +00003897- The methods ``is_in_tuple()``, ``is_vararg()``, and ``is_keywordarg()`` of
3898 symtable.Symbol have been deprecated for removal in 3.0 and the next release.
3899
Amaury Forgeot d'Arc351ffb82008-08-18 19:23:47 +00003900- Issue #2234: distutils failed for some versions of the cygwin compiler. The
3901 version reported by these tools does not necessarily follow the python
3902 version numbering scheme, so the module is less strict when parsing it.
3903
Nick Coghlanf70385a2008-08-18 12:42:46 +00003904- Issue #2235: Added Py3k warnings for types which will become unhashable
3905 under the stricter __hash__ inheritance rules in 3.0. Several types
3906 which did not meet the rules for hash invariants and were already
3907 unhashable in 3.0 have now been explicitly flagged as unhashable in
3908 2.6 as well (collections.Mapping, collections.Set, unittest.TestSuite,
3909 xml.dom.minidom.NamedNodeMap, numbers.Number, UserList.UserList)
3910
Brett Cannon88f801d2008-08-18 00:46:22 +00003911- Update __all__ for cookielib, csv, os, urllib2, and weakref to include things
3912 imported into the module but exposed as part of the module's API.
3913
Brett Cannon7b96f072008-08-18 00:41:11 +00003914- Remove an unneeded import of abc.ABCMeta from 'inspect'.
3915
Brett Cannon46225e72008-08-18 00:36:52 +00003916- Remove unneeded imports of 'sys' and 'warnings' from 'io'.

Brett Cannon25c9d6a2008-08-17 22:10:11 +00003918- Remove unneeded imports of 'warnings' from shelve, filecmp, and dummy_thread.
3919
Hirokazu Yamamoto41a81eb2008-08-17 13:10:46 +00003920- Issue #3575: Incremental decoder's decode function now takes bytearray
3921 by using 's*' instead of 't#'.
3922
Mark Dickinson3e4caeb2009-02-21 20:27:01 +00003923- Issue #2222: Fixed reference leak when occurred os.rename()
Hirokazu Yamamoto7f30a682008-08-17 09:46:56 +00003924 fails unicode conversion on 2nd parameter. (windows only)
3925
Georg Brandl222e2082010-08-01 22:27:39 +00003926- Issue #2464: urllib2 now supports a malformation in the URL received
Facundo Batista94f243a2008-08-17 03:38:39 +00003927 in a redirect.
3928
Brett Cannonabe423e2008-08-16 21:47:07 +00003929- Silence the DeprecationWarning raised when importing mimetools in
Brett Cannon721b1452008-08-16 22:00:27 +00003930 BaseHTTPServer, cgi (and rfc822), httplib.
Brett Cannonabe423e2008-08-16 21:47:07 +00003931
Facundo Batistaeb90b782008-08-16 14:44:07 +00003932- Issue #2776: fixed small issue when handling an URL with double slash
3933 after a 302 response in the case of not going through a proxy.
3934
Antoine Pitroub90a8be2008-08-15 21:03:21 +00003935- Issue #2676: in the email package, content-type parsing was hanging on
3936 pathological input because of quadratic or exponential behaviour of a
3937 regular expression.
3938
Antoine Pitrou11ec65d2008-08-14 21:04:30 +00003939- Issue #3476: binary buffered reading through the new "io" library is now
3940 thread-safe.
3941
Brett Cannonbf3157b2008-08-14 05:00:03 +00003942- Silence the DeprecationWarning of rfc822 when it is imported by mimetools
3943 since mimetools itself is deprecated. Because modules are cached, all
3944 subsequent imports of rfc822 will not raise a visible DeprecationWarning.
3945
Antoine Pitrou9fcd4b32008-08-11 17:21:36 +00003946- Issue #3134: shutil referenced undefined WindowsError symbol.
3947
Robert Schuppenies14646332008-08-10 11:01:53 +00003948- Issue #1342811: Fix leak in Tkinter.Menu.delete. Commands associated to
3949 menu entries were not deleted.
3950
Brett Cannon83e81842008-08-09 23:30:55 +00003951- Copied the implementation of reduce() to _functools.reduce() to have a
3952 version that did not raise a DeprecationWarning under -3.
3953
Antoine Pitrou76b8bee2008-08-09 17:27:23 +00003954- Issue #3205: When iterating over a BZ2File fails allocating memory, raise
3955 a MemoryError rather than silently stop the iteration.
3956
Guido van Rossum59ce9012008-08-09 14:55:34 +00003957- Issue #3487: sre "bytecode" validator. Passing invalid "re-bytecode"
3958 to _sre.compile() will now be rejected. This should not affect anybody
3959 since the re.compile() function never generates invalid re-bytecode.
3960
Skip Montanaroa032bf42008-08-08 22:52:51 +00003961- Issue #3436: Make csv.DictReader's fieldnames attribute a property so that
3962 upon first access it can be automatically initialized from the csv file if
3963 it wasn't initialized during instantiation.
3964
Brett Cannon3aa2a492008-08-06 22:28:09 +00003965- Issue #2338: Create imp.reload() to help with transitioning to Python 3.0 as
3966 the reload() built-in has been removed.
3967
Brett Cannon7e30b672008-08-04 21:52:25 +00003968- Changed code in the following modules/packages to remove warnings raised

Raymond Hettingere3ae6552008-06-20 04:18:15 +00004036Core and Builtins
4037-----------------
4038
Georg Brandl3e483f62008-07-16 22:57:41 +00004039- Issue #3156: Fix inconsistent behavior of the bytearray type: all
4040 its methods now allow for items objects that can be converted to
4041 an integer using operator.index().
4042
Mark Dickinson64b7e502008-07-16 09:40:03 +00004043- Issue #3360: Fix incorrect parsing of '020000000000.0', which
4044 produced a ValueError instead of giving the correct float.
4045
Eric Smitha5fa5a22008-07-16 00:11:49 +00004046- Issue #3083: Add alternate (#) formatting for bin, oct, hex output
4047 for str.format(). This adds the prefix 0b, 0o, or 0x, respectively.
4048
Mark Dickinson7103aa42008-07-15 19:08:33 +00004049- Issue #3008: the float type has a new instance method 'float.hex'
4050 and a new class method 'float.fromhex' to convert floating-point
4051 numbers to and from hexadecimal strings, respectively.
4052
Nick Coghlan6d6bd442008-07-15 15:40:22 +00004053- Issue #2235: __hash__ is once again inherited by default. To allow
4054 collections.Hashable to remain meaningful in the presence of the
4055 default hash implementation (object.__hash__), it is now possible
4056 to explicit block inheritance of hash by setting __hash__=None at
4057 the Python level, or tp_hash=PyObject_HashNotImplemented at the C
4058 level.
4059
Nick Coghlanb028f502008-07-13 14:52:36 +00004060- Issue #3221: Issue a RuntimeWarning instead of raising SystemError if
4061 the parent module cannot be found while performing an absolute import.
4062 This means that an incorrectly defined __package__ attribute will
4063 now only prevent relative imports in that module rather than causing
4064 all imports from that module to fail.
4065
Nick Coghlan14ff9942008-07-08 14:21:42 +00004066- Issue #2517: Allow unicode messages in Exceptions again by correctly

4076 another thread's dictionary.
4077
Mark Dickinson1ec2fcd2008-06-20 14:53:43 +00004078- Issue #3004: Minor change to slice.indices(): the start and stop
4079 arguments are now treated identically, making the behaviour easier
4080 to describe and understand. For example, slice(None, -10,
4081 1).indices(9) now returns (0, 0, 1) instead of (0, -1, 1), and
4082 slice(None, 10, -1).indices(10) returns (9, 9, -1) instead of (9,
4083 10, -1).
4084
Georg Brandl278fc502008-07-19 12:46:12 +00004085- Issue #3219: Calling a function with repeated keyword arguments,
4086 f(a=2, a=23), would not cause a syntax error. This was a regression
4087 from 2.4 caused by the switch to the new compiler.

Amaury Forgeot d'Arc0f7cddc2008-07-06 21:34:39 +00004125- Issue #839496: SimpleHTTPServer used to open text files in text mode. This is
4126 both unnecessary (HTTP allows text content to be sent in several forms) and
Andrew M. Kuchlingcc3f2b12008-07-10 14:43:31 +00004127 wrong because the actual transmitted size could differ from the
Amaury Forgeot d'Arc0f7cddc2008-07-06 21:34:39 +00004128 content-length. The problem had been corrected in the 2.4 branch, but never
4129 merged into trunk.

Nick Coghlanc060b0e2008-07-02 13:09:19 +00004144- Issue #3190: Pydoc now hides the automatic module attribute __package__ (the
4145 handling is now the same as that of other special attributes like __name__).
4146
Brett Cannon8bb8fa52008-07-02 01:57:08 +00004147- Issue #2885 (partial): The urllib.urlopen() function has been deprecated for

Ronald Oussoren5640ce22008-06-05 12:58:24 +00004535- On MacOS X it is now possible to install the framework in 64-bit
4536 mode or even as a 4-way universal binary (that is, PPC, i386,
Georg Brandl5cc774e2008-06-11 20:28:06 +00004537 PPC64 and x86_64 support in one binary).
Ronald Oussoren5640ce22008-06-05 12:58:24 +00004538
4539 This is controlled by the configure argument ``--with-universal-archs``:
4540
4541 - ``--with-universal-archs=all``: install 4-way universal
4542
4543 - ``--with-universal-archs=32-bit``: install 2-way universal, 32-bit (the default)
4544
4545 - ``--with-universal-archs=64-bit``: install 2-way universal, 64-bit
4546
4547 This option should be used in combination with ``--enable-universalsdk=``.
4548
4549 NOTE: 64-bit and 4-way builds are only suppported on Mac OS X 10.5 (or later).

4554
Georg Brandl74a1dea2008-05-28 11:21:39 +00004555- Add ``PyType_Modified()`` as a public API to clear the type cache.
4556
4557- The PyBytes functions have been renamed to PyByteArray.
Christian Heimes7a990612008-05-26 13:15:11 +00004558
4559- The PyString functions have been renamed to PyBytes. A batch of
4560 defines were added so that the linker still sees the original
4561 PyString names.

Georg Brandl3ee81df2008-05-17 18:14:43 +00004599- Issue #1631171: Re-implement the 'warnings' module in C (the
4600 original Python code has been kept as backup). This will allow for
4601 using the 'warning's machinery in such places as the parser where
4602 use of pure Python code is not possible. Both the ``showarning()``
4603 and ``formatwarning()`` gain an optional 'line' argument which is
4604 not called by default for backwards-compatibility reasons. Setting
4605 ``warnings.showwarning()`` to an implementation that lacks support
4606 for the ``line`` argument will raise a DeprecationWarning.

Gregory P. Smithd59fefb2008-04-22 08:11:33 +00004631- The getpass module has been improved on Unix. It now uses /dev/tty
4632 by default and uses stderr instead of stdout. A GetPassWarning is
4633 issued when input echo cannot be controlled.

Georg Brandl3ee81df2008-05-17 18:14:43 +00004648- Issue #2513: distutils on Windows is now capable of cross-compiling
Mark Hammond495cf992008-04-07 01:53:39 +00004649 extension modules between 32 and 64 bit platforms. See the distutls

Georg Brandl3ee81df2008-05-17 18:14:43 +00004669- Issue #2550: The approach used by client/server code for obtaining
4670 ports to listen on in network-oriented tests has been refined in an
4671 effort to facilitate running multiple instances of the entire
4672 regression test suite in parallel without issue.
4673 test_support.bind_port() has been fixed such that it will always
4674 return a unique port -- which wasn't always the case with the
4675 previous implementation, especially if socket options had been set
4676 that affected address reuse (i.e. SO_REUSEADDR, SO_REUSEPORT). The
4677 new implementation of bind_port() will actually raise an exception
4678 if it is passed an AF_INET/SOCK_STREAM socket with either the
4679 SO_REUSEADDR or SO_REUSEPORT socket option set. Furthermore, if
4680 available, bind_port() will set the SO_EXCLUSIVEADDRUSE option on
4681 the socket it's been passed. This currently only applies to
4682 Windows. This option prevents any other sockets from binding to the
4683 host/port we've bound to, thus removing the possibility of the
4684 'non-deterministic' behaviour, as Microsoft puts it, that occurs
4685 when a second SOCK_STREAM socket binds and accepts to a host/port
4686 that's already been bound by another socket. The optional preferred
4687 port parameter to bind_port() has been removed. Under no
4688 circumstances should tests be hard coding ports!
4689
4690 test_support.find_unused_port() has also been introduced, which will
4691 pass a temporary socket object to bind_port() in order to obtain an
4692 unused port. The temporary socket object is then closed and
4693 deleted, and the port is returned. This method should only be used
4694 for obtaining an unused port in order to pass to an external program
4695 (i.e. the -accept [port] argument to openssl's s_server mode) or as
4696 a parameter to a server-oriented class that doesn't give you direct
4697 access to the underlying socket used.
4698
4699 Finally, test_support.HOST has been introduced, which should be used
4700 for the host argument of any relevant socket calls (i.e. bind and
4701 connect).
Trent Nelsone41b0062008-04-08 23:47:30 +00004702
4703 The following tests were updated to following the new conventions:
Georg Brandl3ee81df2008-05-17 18:14:43 +00004704 test_socket, test_smtplib, test_asyncore, test_ssl, test_httplib,
Trent Nelsone41b0062008-04-08 23:47:30 +00004705 test_poplib, test_ftplib, test_telnetlib, test_socketserver,
4706 test_asynchat and test_socket_ssl.
4707
Georg Brandl3ee81df2008-05-17 18:14:43 +00004708 It is now possible for multiple instances of the regression test
4709 suite to run in parallel without issue.

Eric Smitha73fbe72008-02-23 03:09:44 +00004988- Added the future_builtins module, which contains hex() and oct().
4989 These are the PEP 3127 version of these functions, designed to be
4990 compatible with the hex() and oct() builtins from Python 3.0. They
4991 differ slightly in their output formats from the existing, unchanged
4992 Python 2.6 builtins. The expected usage of the future_builtins
4993 module is:
4994 from future_builtins import hex, oct
4995
Eric Smith7ef40bf2008-02-20 23:34:22 +00004996- Issue #1600: Modifed PyOS_ascii_formatd to use at most 2 digit
4997 exponents for exponents with absolute value < 100. Follows C99
4998 standard. This is a change on Windows, which would use 3 digits.
4999 Also, added 'n' to the formats that PyOS_ascii_formatd understands,
5000 so that any alterations it does to the resulting string will be
5001 available in stringlib/formatter.h (for float.__format__).
5002
Eric Smith5a3c1352008-02-19 13:21:56 +00005003- Implemented PEP 3101, Advanced String Formatting. This adds a new
5004 builtin format(); a format() method for str and unicode; a
5005 __format__() method to object, str, unicode, int, long, float, and
5006 datetime; the class string.Formatter; and the C API
5007 PyObject_Format().
5008
Georg Brandl3ee81df2008-05-17 18:14:43 +00005009- Fixed several potential crashes, all caused by specially crafted
5010 __del__ methods exploiting objects in temporarily inconsistent
5011 state.

5022 memory to the OS earlier.
Christian Heimes3b718a72008-02-14 12:47:33 +00005023
Georg Brandl3ee81df2008-05-17 18:14:43 +00005024- Issue #2045: Fix an infinite recursion triggered when printing a
5025 subclass of collections.defaultdict, if its default_factory is set
5026 to a bound method.
Amaury Forgeot d'Arcb01aa432008-02-08 00:56:02 +00005027
Christian Heimesf75dbef2008-02-08 00:11:31 +00005028- Fixed a minor memory leak in dictobject.c. The content of the free
5029 list was not freed on interpreter shutdown.
5030
Georg Brandl21e99f42010-03-07 15:23:59 +00005031- Limit free list of method and built-in function objects to 256

5035 functions ``PyInt_CompactFreeList`` and ``PyFloat_CompactFreeList``
Christian Heimes422051a2008-02-04 18:00:12 +00005036 to compact the internal free lists of pre-allocted ints and floats.
5037
Georg Brandl3ee81df2008-05-17 18:14:43 +00005038- Issue #1983: Fixed return type of fork(), fork1() and forkpty()
5039 calls. Python expected the return type int but the fork familie
5040 returns pi_t.

Georg Brandl3ee81df2008-05-17 18:14:43 +00005051- Added ``PyType_ClearCache()`` and ``sys._clear_type_cache`` to clear
5052 the internal lookup cache for ref leak tests.
Christian Heimes908caac2008-01-27 23:34:59 +00005053
Georg Brandl3ee81df2008-05-17 18:14:43 +00005054- Patch #1473257: generator objects gain a gi_code attribute. This is
5055 the same object as the func_code attribute of the function that
5056 produced the generator.
Georg Brandl0cdf9a32008-01-26 14:14:20 +00005057
Georg Brandl3ee81df2008-05-17 18:14:43 +00005058- Issue #1920: "while 0" statements were completely removed by the
5059 compiler, even in the presence of an "else" clause, which is
5060 supposed to be run when the condition is false. Now the compiler
5061 correctly emits bytecode for the "else" suite.
Amaury Forgeot d'Arc31eaafe2008-01-24 22:59:25 +00005062
Guido van Rossumeead05f2008-01-24 18:21:02 +00005063- A few crashers fixed: weakref_in_del.py (issue #1377858);
5064 loosing_dict_ref.py (issue #1303614, test67.py);
5065 borrowed_ref_[34].py (not in tracker).
5066
Vinay Sajipd7cf32e2008-01-24 12:43:33 +00005067- Issue #1069410: The "can't load dll" message box on Windows is
Christian Heimesb2302ba2008-01-23 17:15:06 +00005068 suppressed while an extension is loaded by calling SetErrorMode in
5069 dynload_win.c. The error is still reported properly.
5070
Georg Brandl3ee81df2008-05-17 18:14:43 +00005071- Issue #1915: Python compiles with --enable-unicode=no again. However
Christian Heimes082c9b02008-01-23 14:20:50 +00005072 several extension methods and modules do not work without unicode
5073 support.
5074
Georg Brandl26543b12008-01-21 18:36:51 +00005075- Issue #1882: when compiling code from a string, encoding cookies in the
5076 second line of code were not always recognized correctly.
5077
Georg Brandl14404b62008-01-19 19:27:05 +00005078- Issue #1679: "0x" was taken as a valid integer literal.
5079
Georg Brandl6caad7d2008-01-26 14:19:22 +00005080- Issue #1865: ``bytes`` as an alias for ``str`` and b"" as an alias "" were
Christian Heimes288e89a2008-01-18 18:24:07 +00005081 added.
5082
Christian Heimesc94e2b52008-01-14 04:13:37 +00005083- sys.float_info / PyFloat_GetInfo: The floating point information
5084 object was converted from a dict to a specialized structseq object.
5085
Georg Brandl3ee81df2008-05-17 18:14:43 +00005086- Patch #1816: Added sys.flags structseq. It exposes the status of
5087 most command line arguments and PYTHON* environment variables.
Christian Heimesf31b69f2008-01-14 03:42:48 +00005088
Georg Brandl3ee81df2008-05-17 18:14:43 +00005089- Objects/structseq.c: Implemented new structseq representation. The
5090 patch makes structseqs (e.g. the return value of os.stat) more
5091 readable.
Christian Heimes9c201962008-01-14 03:33:52 +00005092
Georg Brandl3ee81df2008-05-17 18:14:43 +00005093- Patch #1700288: added a type attribute cache that caches method
5094 accesses, resulting in speedups in heavily object-oriented code.
Amaury Forgeot d'Arce4c270c2008-01-14 00:29:41 +00005095
Neal Norwitz3fc15b82008-01-10 05:42:58 +00005096- Bug #1776: __import__() no longer accepts filenames on any platform.
5097 The first parameter to __import__() must be a valid module name.
Christian Heimes3403f152008-01-09 19:56:33 +00005098
Georg Brandlaed6c662008-01-07 17:25:53 +00005099- Patch #1668: renamed THREADDEBUG envvar to PYTHONTHREADDEBUG.
5100
Georg Brandl3ee81df2008-05-17 18:14:43 +00005101- Patch #602345: Add -B command line option, PYTHONDONTWRITEBYTECODE
5102 envvar and sys.dont_write_bytecode attribute. All these can be set
5103 to forbid Python to attempt to write compiled bytecode files.
Georg Brandl2da0fce2008-01-07 17:09:35 +00005104
Georg Brandl3ee81df2008-05-17 18:14:43 +00005105- Improve some exception messages when Windows fails to load an
5106 extension module. Now we get for example '%1 is not a valid Win32
5107 application' instead of 'error code 193'.
Amaury Forgeot d'Arce0b76952008-01-04 02:04:15 +00005108
Georg Brandl3ee81df2008-05-17 18:14:43 +00005109- Bug #1481296: Fixed long(float('nan')) != 0L.

Georg Brandl3ee81df2008-05-17 18:14:43 +00005111- Issue #1640: Added math.isinf(x), math.isnan(x) and math.copysign(x,
5112 y) functions.
Christian Heimese2ca4242008-01-03 20:23:15 +00005113
Christian Heimes0a8143f2007-12-18 23:22:54 +00005114- Issue #1635: Platform independent creation and representation of NaN
Georg Brandl3ee81df2008-05-17 18:14:43 +00005115 and INF. float("nan"), float("inf") and float("-inf") now work on
5116 every platform with IEEE 754 semantics.
Christian Heimes0a8143f2007-12-18 23:22:54 +00005117
Georg Brandl3ee81df2008-05-17 18:14:43 +00005118- Compiler now generates simpler and faster code for dictionary
5119 literals. The oparg for BUILD_MAP now indicates an estimated
5120 dictionary size. There is a new opcode, STORE_MAP, for adding
5121 entries to the dictionary.
Raymond Hettingerfd7ed402007-12-18 21:24:09 +00005122
Georg Brandl3ee81df2008-05-17 18:14:43 +00005123- Issue #1638: %zd configure test fails on Linux.
Christian Heimesdb3d6cb2007-12-16 21:39:43 +00005124
Georg Brandl3ee81df2008-05-17 18:14:43 +00005125- Issue #1620: New property decorator syntax was modifying the
5126 decorator in place instead of creating a new decorator object.
Christian Heimes90e10e72007-12-14 02:35:23 +00005127
Georg Brandl3ee81df2008-05-17 18:14:43 +00005128- Issue #1538: Avoid copying string in split/rsplit if the split char
5129 is not found.
Skip Montanaro26015492007-12-08 15:33:24 +00005130
Andrew M. Kuchling395fe442007-12-05 13:27:20 +00005131- Issue #1553: An erroneous __length_hint__ can make list() raise a
Christian Heimes7cc1c6f2007-12-05 12:52:34 +00005132 SystemError.
5133
Nick Coghlanef01d822007-12-03 12:55:17 +00005134- PEP 366: Allow explicit relative imports when executing modules
5135 inside packages with the -m switch via a new module level
5136 __package__ attribute.
5137
Georg Brandl3ee81df2008-05-17 18:14:43 +00005138- Issue #1402: Fix a crash on exit, when another thread is still
5139 running, and if the deallocation of its frames somehow calls the
5140 PyGILState_Ensure() / PyGILState_Release() functions.
Amaury Forgeot d'Arcbe49a902007-11-30 20:37:22 +00005141

5143
Vinay Sajip2bdc48c2008-01-21 18:16:05 +00005144- Issue #1445: Fix a SystemError when accessing the ``cell_contents``
Amaury Forgeot d'Arcce7d10c2007-11-24 13:44:17 +00005145 attribute of an empty cell object.
5146
Georg Brandl3ee81df2008-05-17 18:14:43 +00005147- Issue #1460: The utf-7 incremental decoder did not accept truncated
5148 input. It now correctly saves its state between chunks of data.
Amaury Forgeot d'Arcf57375a2007-11-21 01:38:26 +00005149
Georg Brandl3ee81df2008-05-17 18:14:43 +00005150- Patch #1739468: Directories and zipfiles containing a __main__.py
5151 file can now be directly executed by passing their name to the
5152 interpreter. The directory/zipfile is automatically inserted as the
5153 first entry in sys.path.
Nick Coghlan327a39b2007-11-18 11:56:28 +00005154
Georg Brandl3ee81df2008-05-17 18:14:43 +00005155- Issue #1265: Fix a problem with sys.settrace, if the tracing
5156 function uses a generator expression when at the same time the
5157 executed code is closing a paused generator.
Amaury Forgeot d'Arc0d75f092007-11-13 21:54:28 +00005158
Raymond Hettinger1760c8a2007-11-08 02:52:43 +00005159- sets and frozensets now have an isdisjoint() method.
5160
Raymond Hettinger3f8caa32007-10-24 01:28:33 +00005161- optimize the performance of builtin.sum().
5162
Neal Norwitz44f326e2007-10-05 05:29:17 +00005163- Fix warnings found by the new version of the Coverity checker.
5164
Georg Brandl21e99f42010-03-07 15:23:59 +00005165- The enumerate() built-in function is no longer bounded to sequences
Georg Brandl3ee81df2008-05-17 18:14:43 +00005166 smaller than LONG_MAX. Formerly, it raised an OverflowError. Now,
5167 automatically shifts from ints to longs.
Raymond Hettinger8f669372007-10-03 21:18:11 +00005168
Georg Brandl3ee81df2008-05-17 18:14:43 +00005169- Issue #1686386: Tuple's tp_repr did not take into account the
5170 possibility of having a self-referential tuple, which is possible
5171 from C code. Nor did object's tp_str consider that a type's tp_str
5172 could do something that could lead to an inifinite recursion.
5173 Py_ReprEnter() and Py_EnterRecursiveCall(), respectively, fixed the
5174 issues.
Brett Cannon0b14f242007-09-30 19:45:10 +00005175
Georg Brandl3ee81df2008-05-17 18:14:43 +00005176- Issue #1164: It was possible to trigger deadlock when using the
5177 'print' statement to write to a file since the GIL was not released
5178 as needed. Now PyObject_Print() does the right thing along with
5179 various tp_print implementations of the built-in types and those in
5180 the collections module.
Brett Cannon01531592007-09-17 03:28:34 +00005181
Georg Brandl3ee81df2008-05-17 18:14:43 +00005182- Issue #1147: Exceptions were directly allowing string exceptions in
5183 their throw() method even though string exceptions no longer
5184 allowed.
Brett Cannon4c20bc42007-09-11 21:02:28 +00005185
Georg Brandl3ee81df2008-05-17 18:14:43 +00005186- Issue #1096: Prevent a segfault from getting the repr of a very
5187 deeply nested list by using the recursion counter.
Brett Cannona0c05512007-09-10 21:38:27 +00005188
Brett Cannon1e534b52007-09-07 04:18:30 +00005189- Issue #1202533: Fix infinite recursion calls triggered by calls to
Georg Brandl3ee81df2008-05-17 18:14:43 +00005190 PyObject_Call() never calling back out to Python code to trigger
5191 recursion depth updates/checks. Required the creation of a static
5192 RuntimeError instance in case normalizing an exception put the
5193 recursion check value past its limit. Fixes crashers
5194 infinite_rec_(1|2|4|5).py.
Brett Cannon1e534b52007-09-07 04:18:30 +00005195
Georg Brandl3ee81df2008-05-17 18:14:43 +00005196- Patch #1031213: Decode source line in SyntaxErrors back to its
5197 original source encoding.

Georg Brandl7c3b50d2007-07-12 08:38:00 +00005199- Patch #1673759: add a missing overflow check when formatting floats
5200 with %G.
5201
Georg Brandl3ee81df2008-05-17 18:14:43 +00005202- Prevent expandtabs() on string and unicode objects from causing a
5203 segfault when a large width is passed on 32-bit platforms.
Neal Norwitz7dbd2a32007-06-09 03:36:34 +00005204

Georg Brandl3ee81df2008-05-17 18:14:43 +00005207- Issue #1722485: remove docstrings again when running with -OO.
Georg Brandla5ea6892007-06-01 11:33:33 +00005208
Neal Norwitz0ac60192007-05-27 04:08:54 +00005209- Add new attribute names for function objects. All the func_* become
Georg Brandl3ee81df2008-05-17 18:14:43 +00005210 __*__ attributes. (Some already existed, e.g., __doc__ and
5211 __name__.)
Neal Norwitz0ac60192007-05-27 04:08:54 +00005212
Neal Norwitz8b2bfbc2007-05-23 06:35:32 +00005213- Add -3 option to the interpreter to warn about features that are
5214 deprecated and will be changed/removed in Python 3.0.
5215
Georg Brandl2134e752007-05-21 20:34:16 +00005216- Patch #1686487: you can now pass any mapping after '**' in function
5217 calls.
5218
Collin Winter62903052007-05-18 23:11:24 +00005219- except clauses may now be spelled either "except E, target:" or
Georg Brandl3ee81df2008-05-17 18:14:43 +00005220 "except E as target:". This is to provide forwards compatibility
5221 with Python 3.0.
Collin Winter62903052007-05-18 23:11:24 +00005222
Brett Cannon229cee22007-05-05 01:34:02 +00005223- Deprecate BaseException.message as per PEP 352.
5224
Georg Brandl3ee81df2008-05-17 18:14:43 +00005225- Issue #1303614: don't expose object's __dict__ when the dict is
Georg Brandl21e99f42010-03-07 15:23:59 +00005226 inherited from a built-in base.
Armin Rigo9790a272007-05-02 19:23:31 +00005227
Vinay Sajip8549ce32007-05-06 17:53:37 +00005228- When __slots__ are set to a unicode string, make it work the same as
Neal Norwitzcbd9ee62007-04-14 05:25:50 +00005229 setting a plain string, ie don't expand to single letter identifiers.
5230
Raymond Hettinger13936692007-04-11 18:40:58 +00005231- Request #1191699: Slices can now be pickled.
5232
Raymond Hettinger4db5fe92007-04-12 04:10:00 +00005233- Request #1193128: str.translate() now allows a None argument for
5234 translations that only remove characters without re-mapping the
5235 remaining characters.
5236
Georg Brandl5cb76c12007-03-21 09:00:39 +00005237- Patch #1682205: a TypeError while unpacking an iterable is no longer
5238 masked by a generic one with the message "unpack non-sequence".
5239
Neal Norwitzaa754b72007-03-21 06:39:48 +00005240- Remove unused file Python/fmod.c.
5241
Guido van Rossum143b5642007-03-23 04:58:42 +00005242- Bug #1683368: The object.__init__() and object.__new__() methods are
5243 now stricter in rejecting excess arguments. The only time when
5244 either allows excess arguments is when it is not overridden and the
5245 other one is. For backwards compatibility, when both are
5246 overridden, it is a deprecation warning (for now; maybe a Py3k
Guido van Rossum234b1ff2007-03-23 19:39:01 +00005247 warning later). Also, type.__init__() insists on the same signature
5248 as supported by type.__new__().
Guido van Rossum143b5642007-03-23 04:58:42 +00005249
Georg Brandl3ee81df2008-05-17 18:14:43 +00005250- Patch #1675423: PyComplex_AsCComplex() now tries to convert an
5251 object to complex using its __complex__() method before falling back
5252 to the __float__() method. Therefore, the functions in the cmath
5253 module now can operate on objects that define a __complex__()
5254 method.
Georg Brandl2b869942007-03-17 16:08:45 +00005255
Georg Brandl3ee81df2008-05-17 18:14:43 +00005256- Patch #1623563: allow __class__ assignment for classes with
5257 __slots__. The old and the new class are still required to have the
5258 same slot names.
Žiga Seilnacht6f2d09c2007-03-16 11:59:38 +00005259
Georg Brandl3ee81df2008-05-17 18:14:43 +00005260- Patch #1642547: Fix an error/crash when encountering syntax errors
5261 in complex if statements.

Georg Brandl3ee81df2008-05-17 18:14:43 +00005263- Patch #1462488: Python no longer segfaults when
5264 ``object.__reduce_ex__()`` is called with an object that is faking
5265 its type.
Žiga Seilnacht20f43d32007-03-15 11:44:55 +00005266
Georg Brandl3ee81df2008-05-17 18:14:43 +00005267- Patch #1680015: Don't modify __slots__ tuple if it contains an
5268 unicode name.
Žiga Seilnacht71436f02007-03-14 12:24:09 +00005269
Georg Brandl5240d742007-03-13 20:46:32 +00005270- Patch #1444529: the builtin compile() now accepts keyword arguments.
5271
Georg Brandl7b9c5552007-03-12 14:30:05 +00005272- Bug #1678647: write a newline after printing an exception in any
5273 case, even when converting the value to a string failed.
5274
Georg Brandl871f1bc2007-03-12 13:17:36 +00005275- The dir() function has been extended to call the __dir__() method on
Georg Brandl3ee81df2008-05-17 18:14:43 +00005276 its argument, if it exists. If not, it will work like before. This
5277 allows customizing the output of dir() in the presence of a
5278 __getattr__().
Georg Brandl871f1bc2007-03-12 13:17:36 +00005279
Collin Winter276887b2007-03-12 16:11:39 +00005280- Patch #922167: Python no longer segfaults when faced with infinitely
5281 self-recursive reload() calls (as reported by bug #742342).
5282
Georg Brandl3ee81df2008-05-17 18:14:43 +00005283- Patch #1675981: remove unreachable code from ``type.__new__()``
5284 method.
Žiga Seilnacht89032082007-03-11 15:54:54 +00005285
Georg Brandl3ee81df2008-05-17 18:14:43 +00005286- Patch #1491866: change the complex() constructor to allow
5287 parthensized forms. This means complex(repr(x)) now works instead of
5288 raising a ValueError.

5800
Facundo Batistad918a652007-04-24 13:54:38 +00005801- As specified in RFC 2616, an HTTP response like 2xx indicates that
Georg Brandl3ee81df2008-05-17 18:14:43 +00005802 the client's request was successfully received, understood, and
5803 accepted. Now in these cases no error is raised in urllib (issue
5804 #1177) and urllib2.
Facundo Batistad918a652007-04-24 13:54:38 +00005805

Facundo Batistab6a5c9d2007-03-29 18:22:35 +00005812- Added a timeout parameter to the constructor of other protocols
5813 (telnetlib, ftplib, smtplib and poplib). This is second part of the
5814 work started with create_connection() and timeout in httplib, and
5815 closes patch #723312.
5816
Vinay Sajip8549ce32007-05-06 17:53:37 +00005817- Patch #1676823: Added create_connection() to socket.py, which may be
5818 called with a timeout, and use it from httplib (whose HTTPConnection
Facundo Batista70f996b2007-05-21 17:32:32 +00005819 and HTTPSConnection now accept an optional timeout).
Facundo Batista07c78be2007-03-23 18:54:07 +00005820
Martin v. Löwis0af33882007-03-23 13:27:15 +00005821- Bug #978833: Revert r50844, as it broke _socketobject.dup.

Georg Brandl3ee81df2008-05-17 18:14:43 +00005828- Patch #1273829: os.walk() now has a "followlinks" parameter. If set
5829 to True (which is not the default), it visits symlinks pointing to

5841
Georg Brandlf66b6032007-03-14 08:27:52 +00005842- Bug #767111: fix long-standing bug in urllib which caused an
Georg Brandl3ee81df2008-05-17 18:14:43 +00005843 AttributeError instead of an IOError when the server's response
5844 didn't contain a valid HTTP status line.
Georg Brandlf66b6032007-03-14 08:27:52 +00005845
Georg Brandl3ee81df2008-05-17 18:14:43 +00005846- Patch #957650: "%var%" environment variable references are now
5847 properly expanded in ntpath.expandvars(), also "~user" home

Georg Brandl03b90d82007-03-13 22:07:36 +00005849
Georg Brandl3ee81df2008-05-17 18:14:43 +00005850- Patch #1429539: pdb now correctly initializes the __main__ module
5851 for the debugged script, which means that imports from __main__ work
Georg Brandlb6ae6aa2007-03-13 21:58:44 +00005852 correctly now.
5853
Georg Brandlbad6f192007-03-13 21:32:56 +00005854- The nonobvious commands.getstatus() function is now deprecated.

5860
Georg Brandl3ee81df2008-05-17 18:14:43 +00005861- Patch #1530482: add pydoc.render_doc() which returns the
5862 documentation for a thing instead of paging it to stdout, which
5863 pydoc.doc() does.
Georg Brandl8441f152007-03-13 20:02:57 +00005864
Georg Brandl3ee81df2008-05-17 18:14:43 +00005865- Patch #1533909: the timeit module now accepts callables in addition

5871 parameter which can be set to False to prevent the default
5872 delete-on-close behavior.
Georg Brandl35ef9c12007-03-13 18:31:49 +00005873
Georg Brandl9e6b4702007-03-13 18:15:41 +00005874- Patch #1581073: add a flag to textwrap that prevents the dropping of
5875 whitespace while wrapping.
5876
Georg Brandl92a6bae2007-03-13 17:43:32 +00005877- Patch #1603688: ConfigParser.SafeConfigParser now checks values that
Georg Brandl3ee81df2008-05-17 18:14:43 +00005878 are set for invalid interpolation sequences that would lead to
5879 errors on reading back those values.
Georg Brandl92a6bae2007-03-13 17:43:32 +00005880

5893
Georg Brandl94fe3f52007-03-13 09:32:11 +00005894- Patch #1635454: the csv.DictWriter class now includes the offending
Georg Brandl3ee81df2008-05-17 18:14:43 +00005895 field names in its exception message if you try to write a record
5896 with a dictionary containing fields not in the CSV field names list.

Collin Winter22c42ba2007-03-10 02:51:26 +00005914

5922 returned string up to the first NUL character.
5923

5933
Georg Brandl3ee81df2008-05-17 18:14:43 +00005934- unittest now verifies more of its assumptions. In particular,
5935 TestCase and TestSuite subclasses (not instances) are no longer
5936 accepted in TestSuite.addTest(). This should cause no
5937 incompatibility since it never made sense with ordinary subclasses
5938 -- the failure just occurred later, with a more cumbersome
5939 exception.

5948 given a unicode argument and os.listdir() returns unicode filenames.
5949
Georg Brandl3ee81df2008-05-17 18:14:43 +00005950- Patch #1673619: setup.py identifies extension modules it doesn't

Georg Brandl3ee81df2008-05-17 18:14:43 +00006328 time so that opening a database previously created with the DB_DUP
6329 or DB_DUPSORT flag set will keep the proper behavior on subsequent
6330 opens. Specifically: dictionary assignment to a DB object will
6331 replace all values for a given key when the database allows
6332 duplicate values. DB users should use DB.put(k, v) when they want
6333 to store duplicates; not DB[k] = v.

6340 characters with ASCII value less than 32. Also, it correctly quotes
6341 dots only if they occur on a single line, as opposed to the previous
6342 behavior of quoting dots if they are the second character of any
6343 line.
