200 fix various SSLSocket methods to raise socket.error rather than an
201 unhelpful TypeError when called on an unconnected socket. Original patch
202 by Andrew Bennetts.
203
Raymond Hettinger74f869e2010-09-13 22:14:36 +0000204- Issue #9826: OrderedDict.__repr__ can now handle self-referential
205 values: d['x'] = d.

213 This prevents user-created self-referencing ordered dictionaries from
214 becoming permanently uncollectable GC garbage. The downside is that
215 removing __del__ means that the internal doubly-linked list has to wait for
216 GC collection rather than freeing memory immediately when the refcnt drops
217 to zero.
218
Raymond Hettingerffd2a422010-09-10 10:47:22 +0000219- Issue #9816: random.Random.jumpahead(n) did not produce a sufficiently

Raymond Hettingerffd2a422010-09-10 10:47:22 +0000221 value.
222
Antoine Pitrouc818ed42010-09-07 21:40:25 +0000223- Issue #9792: In case of connection failure, socket.create_connection()
224 would swallow the exception and raise a new one, making it impossible
225 to fetch the original errno, or to filter timeout errors. Now the
226 original error is re-raised.
227
Antoine Pitrouf4f61712010-09-07 16:34:47 +0000228- Issue #9758: When fcntl.ioctl() was called with mutable_flag set to True,
229 and the passed buffer was exactly 1024 bytes long, the buffer wouldn't
230 be updated back after the system call. Original patch by Brian Brazil.
231
Antoine Pitroudca9de92010-09-04 17:52:26 +0000232- Issue #1100562: Fix deep-copying of objects derived from the list and
233 dict types. Patch by Michele Orrù and Björn Lindqvist.
234
Fred Drakea1e627d2010-09-03 03:55:50 +0000235- Issue #7005: Fixed output of None values for RawConfigParser.write and
236 ConfigParser.write.
237
Daniel Stutzbach66c981b2010-08-31 20:29:39 +0000238- Issue #808164: Fixed socket.close to avoid references to globals, to
239 avoid issues when socket.close is called from a __del__ method.
240
Terry Reedyd2d2ae92010-11-11 23:22:19 +0000241- Issue #2986: difflib.SequenceMatcher gets a new parameter, autojunk, which

243 heuristic. Patch by Terry Reedy and Eli Bendersky
244
Senthil Kumaran7e8fd5e2010-08-26 06:20:13 +0000245- Issue #8797: urllib2 does a retry for Basic Authentication failure instead of
246 falling into recursion.
247
R. David Murray7c4bf552010-08-25 01:45:57 +0000248- Issue #1194222: email.utils.parsedate now returns RFC2822 compliant four
249 character years even if the message contains RFC822 two character years.
250
Daniel Stutzbach91287322010-08-24 21:09:30 +0000251- Issue #8750: Fixed MutableSet's methods to correctly handle
252 reflexive operations, namely x -= x and x ^= x.
253
Victor Stinnercaafd772010-09-08 10:51:01 +0000254- Issue #9129: smtpd.py is vulnerable to DoS attacks deriving from missing

258 errors.

263 module now correctly return a set. (Patch by Eli Bendersky.)
264
Antoine Pitrou3ebaed62010-08-21 19:17:25 +0000265- Issue #9617: Signals received during a low-level write operation aren't
266 ignored by the buffered IO layer anymore.
267
Benjamin Peterson52c36052010-08-21 03:03:22 +0000268- Issue #2521: Use weakrefs on for caching in the abc module, so that classes
269 are not held onto after they are deleted elsewhere.
270
Raymond Hettingera54b2da2010-08-17 19:03:06 +0000271- Issue #9626: the view methods for collections.OrderedDict() were returning
272 the unordered versions inherited from dict. Those methods are now
273 overridden to provide ordered views.
274
Éric Araujo0389ae62010-08-14 03:07:46 +0000275- Issue #8688: MANIFEST files created by distutils now include a magic

281 case in Python 2.5 and earlier).
282
Antoine Pitroucb4f47c2010-08-11 13:40:17 +0000283- Issue #9550: a BufferedReader could issue an additional read when the
284 original read request had been satisfied, which could block indefinitely
285 when the underlying raw IO channel was e.g. a socket. Report and original
286 patch by Jason V. Miller.
287
Fred Drake0a1fa0e2010-08-10 13:09:54 +0000288- Issue #9551: Don't raise TypeError when setting the value to None for

290
Antoine Pitrou8cdede42010-08-10 00:04:13 +0000291- Issue #6915: Under Windows, os.listdir() didn't release the Global

Ezio Melottiab2eb0e2010-06-05 19:21:32 +0000675- Issue #8271: during the decoding of an invalid UTF-8 byte sequence, only the
676 start byte and the continuation byte(s) are now considered invalid, instead
677 of the number of bytes specified by the start byte.
678 E.g.: '\xf1\x80AB'.decode('utf-8', 'replace') now returns u'\ufffdAB' and
679 replaces with U+FFFD only the start byte ('\xf1') and the continuation byte
680 ('\x80') even if '\xf1' is the start byte of a 4-bytes sequence.
681 Previous versions returned a single u'\ufffd'.

Mark Dickinson4ca7c3c2010-05-30 13:18:10 +0000689- Issue #8748: Fix two issues with comparisons between complex and integer
690 objects. (1) The comparison could incorrectly return True in some cases
691 (2**53+1 == complex(2**53) == 2**53), breaking transivity of equality.
692 (2) The comparison raised an OverflowError for large integers, leading
693 to unpredictable exceptions when combining integers and complex objects
694 in sets or dicts.

1078 code. If a derived class does not currently implement __format__ but later
1079 adds its own __format__, it would most likely break user code that had
1080 supplied a format string. This will be changed to a DeprecationWaring in

1133 NaN are unchanged.) Also, Decimal quiet NaNs are now hashable; Decimal
1134 signaling NaNs remain unhashable.

Antoine Pitroud840e512010-02-04 20:20:18 +00001562- Issue #4772: Raise a ValueError when an unknown Bluetooth protocol is
Georg Brandlba83f822010-03-14 09:50:54 +00001563 specified, rather than fall through to AF_PACKET (in the ``socket`` module).
Antoine Pitroud840e512010-02-04 20:20:18 +00001564 Also, raise ValueError rather than TypeError when an unknown TIPC address

Antoine Pitrouf3fa0742010-01-31 22:26:04 +00001569- Issue #6939: Fix file I/O objects in the `io` module to keep the original
Georg Brandlba83f822010-03-14 09:50:54 +00001570 file position when calling `truncate()`. It would previously change the file
1571 position to the given argument, which goes against the tradition of
Antoine Pitrouf3fa0742010-01-31 22:26:04 +00001572 ftruncate() and other truncation APIs. Patch by Pascal Chambon.
1573

1575 class used to represent files stored inside an archive. The new
1576 implementation is significantly faster and can be wrapped in a
1577 ``io.BufferedReader`` object for more speedups. It also solves an issue
1578 where interleaved calls to ``read()`` and ``readline()`` give wrong results.

1591 encoded string for them. This ensures that the upload and register commands
1592 send the correct values to PyPI without any error.

1668
Georg Brandlba83f822010-03-14 09:50:54 +00001669- The ``__complex__()`` method is now looked up on the class of instances to
1670 make it consistent with other special methods.

Antoine Pitrou5b7139a2010-01-02 21:12:58 +00001672- Issue #7462: Implement the stringlib fast search algorithm for the `rfind`,
1673 `rindex`, `rsplit` and `rpartition` methods. Patch by Florent Xicluna.
1674
Mark Dickinson1b34d252010-01-01 17:27:30 +00001675- Issue #5080: A number of functions and methods previously produced a
Georg Brandlba83f822010-03-14 09:50:54 +00001676 DeprecationWarning when passed a float argument where an integer was expected.
1677 These functions and methods now raise TypeError instead. The majority of the
1678 effects of this change are in the extension modules, but some core functions
1679 and methods are affected: notably the 'chr', 'range' and 'xrange' builtins,
1680 and many unicode/str methods.

1694 of integers: the result of a/b is now correctly rounded for ints a and b (at
1695 least on IEEE 754 platforms), and in particular does not depend on the
1696 internal representation of a long.

Georg Brandlba83f822010-03-14 09:50:54 +00001705 These executables now work properly with the arch(1) command: ``arch -ppc

Georg Brandlba83f822010-03-14 09:50:54 +00001845- Issue #3382: 'F' formatting for float and complex now convert the result to
1846 upper case. This only affects 'inf' and 'nan', since 'f' no longer converts
1847 to 'g' for large values.
Amaury Forgeot d'Arcd7288712009-12-01 21:51:04 +00001848
Georg Brandlba83f822010-03-14 09:50:54 +00001849- Remove switch from "%f" formatting to "%g" formatting for floats larger than
1850 1e50 in absolute value.
Mark Dickinson9dd5e162009-11-23 20:54:09 +00001851
Georg Brandlba83f822010-03-14 09:50:54 +00001852- Remove restrictions on precision when formatting floats. E.g., "%.120g" %
1853 1e-100 used to raise OverflowError, but now gives the requested 120
1854 significant digits instead.
Mark Dickinson18cfada2009-11-23 18:46:41 +00001855
Georg Brandlba83f822010-03-14 09:50:54 +00001856- Add Py3k warnings for parameter names in parentheses.

1861 10.6.
Ronald Oussoren315cd0c2009-11-19 16:25:21 +00001862
Georg Brandlba83f822010-03-14 09:50:54 +00001863- Issue #7117: ``repr(x)`` for a float x returns a result based on the shortest
1864 decimal string that's guaranteed to round back to x under correct rounding
1865 (with round-half-to-even rounding mode). Previously it gave a string based on
1866 rounding x to 17 decimal digits. repr(x) for a complex number behaves
1867 similarly. On platforms where the correctly-rounded strtod and dtoa code is
1868 not supported (see below), repr is unchanged.
Mark Dickinsonb678de82009-11-19 18:41:49 +00001869
Georg Brandlba83f822010-03-14 09:50:54 +00001870- Issue #7117: On almost all platforms: float-to-string and string-to-float
1871 conversions within Python are now correctly rounded. Places these conversions
1872 occur include: str for floats and complex numbers; the float and complex
1873 constructors; old-style and new-style numeric formatting; serialization and
1874 deserialization of floats and complex numbers using marshal, pickle and json;
1875 parsing of float and imaginary literals in Python code; Decimal-to-float
1876 conversion.
Mark Dickinsonb678de82009-11-19 18:41:49 +00001877
Georg Brandlba83f822010-03-14 09:50:54 +00001878 The conversions use a Python-adapted version of David Gay's well-known dtoa.c,
1879 providing correctly-rounded strtod and dtoa C functions. This code is
1880 supported on Windows, and on Unix-like platforms using gcc, icc or suncc as
1881 the C compiler. There may be a small number of platforms on which correct
1882 operation of this code cannot be guaranteed, so the code is not used: notably,
1883 this applies to platforms where the C double format is not IEEE 754 binary64,
1884 and to platforms on x86 hardware where the x87 FPU is set to 64-bit precision
1885 and Python's configure script is unable to determine how to change the FPU
1886 precision. On these platforms conversions use the platform strtod and dtoa,
1887 as before.

Georg Brandlba83f822010-03-14 09:50:54 +00001889- Issue #7117: Backport round implementation from Python 3.x. ``round()`` now
1890 uses the correctly-rounded string <-> float conversions described above (when
1891 available), and so produces correctly rounded results that will display nicely
1892 under the float repr. There are two related small changes: (1) round now
1893 accepts any class with an ``__index__()`` method for its second argument (but
1894 no longer accepts floats for the second argument), and (2) an excessively
1895 large second integer argument (e.g., ``round(1.234, 10**100)``) no longer
1896 raises an exception.

1899
Georg Brandlba83f822010-03-14 09:50:54 +00001900- Fix several issues with ``compile()``. The input can now contain Windows and

2046 of 12. Previously, the behavior the same but with a default precision of 6.
2047 This more closely matches ``str()``, and reduces surprises when adding

2275 this code path is really executed because I cannot move to such directory on

Georg Brandlba83f822010-03-14 09:50:54 +00003461- Issue #6561: '\d' in a regex now matches only characters with Unicode category
3462 'Nd' (Number, Decimal Digit). Previously it also matched characters with
3463 category 'No'.
Mark Dickinsonfe67bd92009-07-28 20:35:03 +00003464
Georg Brandlba83f822010-03-14 09:50:54 +00003465- Issue #1523: Remove deprecated overflow wrapping for struct.pack with an
3466 integer format code ('bBhHiIlLqQ'). Packing an out-of-range integer now
3467 consistently raises struct.error.
Mark Dickinson5fd3af22009-07-07 15:08:28 +00003468
Georg Brandlba83f822010-03-14 09:50:54 +00003469- Issues #1530559, #1741130: Fix various struct.pack inconsistencies for the

Mark Dickinson463dc4b2009-07-05 10:01:24 +00003472
Georg Brandlba83f822010-03-14 09:50:54 +00003473 - Packing a float now always gives a Deprecation Warning. Previously it
3474 only warned for 'I', 'L', '*B', '*H', '*I', '*L'.
Mark Dickinson463dc4b2009-07-05 10:01:24 +00003475
Georg Brandlba83f822010-03-14 09:50:54 +00003476 - If x is not an int, long or float, then packing x will always result in
3477 struct.error. Previously an x with an __int__ method could be packed by
3478 'b', 'B', 'h', 'H', 'i', 'l', '*b', '*h' ,'*i', '*l', and an x with a
3479 __long__ method could be packed by 'q', 'Q', '*q', '*Q'; for x with
3480 neither __int__ nor __long__, TypeError used to be raised (with a
3481 confusing error message) for 'I', 'L', '*B', '*H', '*I', '*L', and
3482 struct.error in other cases.
Mark Dickinson463dc4b2009-07-05 10:01:24 +00003483
Georg Brandlba83f822010-03-14 09:50:54 +00003484 Note: as of Python 2.7 beta 1, the above is out of date. In 2.7 beta 1, any
3485 argument with an __int__ method can be packed, but use of this feature
3486 triggers a DeprecationWarning.

3494 supporting objects as input no matter how it was compiled (built in
Gregory P. Smithfe32d302010-01-02 22:42:50 +00003495 implementations or external openssl library). NOTE: Undone in 2.7a2.

Georg Brandlba83f822010-03-14 09:50:54 +00003519- Issue #7431: Use TESTFN in test_linecache instead of trying to create a file
3520 in the Lib/test directory, which might be read-only for the user running the
3521 tests.
R. David Murray820b0ea2009-12-03 23:57:59 +00003522
Georg Brandlba83f822010-03-14 09:50:54 +00003523- Issue #7324: Add a sanity check to regrtest argument parsing to catch the case
3524 of an option with no handler.
R. David Murrayda826892009-11-15 00:04:32 +00003525
Georg Brandlba83f822010-03-14 09:50:54 +00003526- Issue #7312: Add a -F flag to run the selected tests in a loop until a test
3527 fails. Can be combined with -j.
R. David Murray7f7eea62009-11-14 15:18:22 +00003528
Antoine Pitrou310c9fe2009-11-11 20:55:07 +00003529- Issue #7295: Do not use a hardcoded file name in test_tarfile.

Antoine Pitrouc98efe02009-11-06 22:34:35 +00003531- Issue #7270: Add some dedicated unit tests for multi-thread synchronization
3532 primitives such as Lock, RLock, Condition, Event and Semaphore.
3533
Antoine Pitrou59c44f32009-10-30 17:07:08 +00003534- Issue #7222: Make thread "reaping" more reliable so that reference
Georg Brandlba83f822010-03-14 09:50:54 +00003535 leak-chasing test runs give sensible results. The previous method of reaping
3536 threads could return successfully while some Thread objects were still
3537 referenced. This also introduces a new private function: ``thread._count()``.
Antoine Pitrou59c44f32009-10-30 17:07:08 +00003538
Georg Brandlba83f822010-03-14 09:50:54 +00003539- Issue #7151: Fixed regrtest -j so that output to stderr from a test no longer
3540 runs the risk of causing the worker thread to fail.
R. David Murray282396f2009-10-18 21:12:37 +00003541
Antoine Pitrou58d2f262009-10-10 20:52:11 +00003542- Issue #7055: test___all__ now greedily detects all modules which have an
3543 __all__ attribute, rather than using a hardcoded and incomplete list.
3544
R. David Murray14dcd432009-10-14 13:58:07 +00003545- Issue #7058: Added save/restore for things like sys.argv and cwd to
3546 runtest_inner in regrtest, with warnings if the called test modifies them,
3547 and a new section in the summary report at the end.
R. David Murrayabe3d3e2009-10-05 17:03:09 +00003548
Mark Dickinson245d9152009-10-04 18:38:39 +00003549- Issue #7042: Fix test_signal (test_itimer_virtual) failure on OS X 10.6.

3552 off the trailing 0 in the version number.
3553
Guilherme Polo7f146ab2009-06-21 17:22:50 +00003554- Issue #5450: Moved tests involving loading tk from Lib/test/test_tcl to
3555 Lib/lib-tk/test/test_tkinter/test_loadtk. With this, these tests demonstrate
Georg Brandlba83f822010-03-14 09:50:54 +00003556 the same behaviour as test_ttkguionly (and now also test_tk) which is to skip
3557 the tests if DISPLAY is defined but can't be used.
Guilherme Polo7f146ab2009-06-21 17:22:50 +00003558
Antoine Pitrou4698d992009-05-31 14:20:14 +00003559- Issue #6152: New option '-j'/'--multiprocess' for regrtest allows running
3560 regression tests in parallel, shortening the total runtime.
3561
Georg Brandlba83f822010-03-14 09:50:54 +00003562- Issue #5354: New test support function import_fresh_module() makes it easy to
3563 import both normal and optimised versions of modules. test_heapq and
3564 test_warnings have been adjusted to use it, tests for other modules with both
3565 C and Python implementations in the stdlib can be adjusted to use it over
3566 time.

3573
Georg Brandlba83f822010-03-14 09:50:54 +00003574- regrtest no longer treats ImportError as equivalent to SkipTest. Imports that
3575 should cause a test to be skipped are now done using import_module from test
3576 support, which does the conversion.
R. David Murray41448c52009-03-31 19:57:24 +00003577
Guilherme Polob1a98de2009-01-28 20:03:26 +00003578- Issue #5083: New 'gui' resource for regrtest.

3678
Amaury Forgeot d'Arc05e34492008-09-10 22:04:45 +00003679- Issue #3743: In a few places, PY_FORMAT_SIZE_T was incorrectly used with
3680 PyString_FromFormat or PyErr_Format to display size_t values. The macro
3681 PY_FORMAT_SIZE_T is designed to select the correct format for the OS
3682 ``printf`` function, whereas PyString_FromFormat has an independent
3683 implementation and uses "%zd" on all platforms for size_t values.
3684 This makes a difference on win64, where ``printf`` needs "%Id" to display
3685 64bit values.

Benjamin Peterson97179b02008-09-09 20:55:01 +00003687- Issue #3634: _weakref.ref(Exception).__init__() gave invalid return value on

Antoine Pitroud4ae97b2008-08-29 18:39:48 +00003700- Issue #3668: Fix a memory leak with the "s*" argument parser in
Vinay Sajip35e3b032008-09-01 14:33:59 +00003701 PyArg_ParseTuple and friends, which occurred when the argument for "s*"
Antoine Pitroud4ae97b2008-08-29 18:39:48 +00003702 was correctly parsed but parsing of subsequent arguments failed.
3703
Vinay Sajip35e3b032008-09-01 14:33:59 +00003704- Issue #2534: speed up isinstance() and issubclass() by 50-70%, so as to
Antoine Pitrou0668c622008-08-26 22:42:08 +00003705 match Python 2.5 speed despite the __instancecheck__ / __subclasscheck__
3706 mechanism. In the process, fix a bug where isinstance() and issubclass(),
3707 when given a tuple of classes as second argument, were looking up
3708 __instancecheck__ / __subclasscheck__ on the tuple rather than on each
3709 type object.
3710
Neal Norwitz18aa3882008-08-24 05:04:52 +00003711- Fix crashes on memory allocation failure found with failmalloc.

Brett Cannon1eaf0742008-09-02 01:25:16 +00003780 warnings.catch_warnings() along with some API cleanup. Expanding the tests
3781 for catch_warnings() also led to an improvement in the raising of a
3782 DeprecationWarning related to warnings.warn_explicit().
3783
Benjamin Peterson973e6c22008-09-01 23:12:58 +00003784- The deprecation warnings for the old camelCase threading API were removed.

3806
Amaury Forgeot d'Arc293924b2008-09-02 23:19:56 +00003807- Issue #2975: When compiling several extension modules with Visual Studio 2008
3808 from the same python interpreter, some environment variables would grow
3809 without limit.
3810
Benjamin Peterson37346b22008-08-23 20:27:43 +00003811- Issue #3643: Added a few more checks to _testcapi to prevent segfaults by
3812 exploitation of poor argument checking.
3813
Gerhard Häringef2276b2008-09-12 13:54:06 +00003814- sqlite3: Changed docstring of iterdump() to mark method as "Non-standard".

Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00003848What's New in Python 2.6 beta 3?
3849================================
3850
Barry Warsaw07a4a382008-08-21 01:15:08 +00003851*Release date: 20-Aug-2008*
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00003852
3853Core and Builtins
3854-----------------
3855
Guido van Rossumf8402962008-08-20 15:01:50 +00003856- Issue #1878: Remove Py_TPFLAGS_HAVE_VERSION_TAG from
3857 Py_TPFLAGS_DEFAULT when not building the core. This means 3rd party
3858 extensions do not automatically benefit from the class attribute
3859 cache; they will have to explicitly add Py_TPFLAGS_HAVE_VERSION_TAG
3860 to their tp_flags field if they care. This is a backwards
3861 compatibility feature; in 3.0, all types will use the cache by
3862 default.
3863
Benjamin Petersonf647dc12008-08-20 01:27:30 +00003864- Keyword arguments can now follow starred arguments. (``f(a, *args,
3865 keyword=23)`` is now valid syntax.)
3866
Thomas Heller0ad5ae02008-08-19 19:25:04 +00003867- ctypes function pointers that are COM methods have a boolean True
3868 value again.
3869
Martin v. Löwisf91d46a2008-08-12 14:49:50 +00003870- Issue #3139: Make buffer-interface thread-safe wrt. PyArg_ParseTuple,
3871 by denying s# to parse objects that have a releasebuffer procedure,
3872 and introducing s*.
3873
Georg Brandl1e13ea92008-08-11 09:07:59 +00003874- Issue #3537: Fix an assertion failure when an empty but presized dict
3875 object was stored in the freelist.
3876
Mark Dickinsonb6467572008-08-04 21:30:09 +00003877- Issue #1481296: Make long(float('nan')) and int(float('nan')) raise
3878 ValueError consistently across platforms.
3879
Amaury Forgeot d'Arc39fd6722008-07-31 21:28:03 +00003880- Issue #3479: On platforms where sizeof(int) is smaller than sizeof(long)
3881 (64bit Unix, for example), unichr() would truncate its argument and return
3882 u'\x00' for unichr(2**32). Now it properly raises an OverflowError.
3883
Neal Norwitze7d8be82008-07-31 17:17:14 +00003884- Apply security patches from Apple.
3885
Amaury Forgeot d'Arc246daed2008-07-31 00:42:16 +00003886- Issue #2542: Now that issubclass() may call arbitrary code, ensure that
3887 PyErr_ExceptionMatches returns 0 when an exception occurs there.
3888
Antoine Pitrou92f82162008-07-25 22:22:08 +00003889- Issue #1819: function calls with several named parameters are now on
3890 average 35% faster (as measured by pybench).
3891
Amaury Forgeot d'Arce4921fe2008-07-21 22:00:38 +00003892- Issue #2378: An unexpected UnboundLocalError or NameError could appear when
3893 the python debugger steps into a class statement: the free variables (local
3894 variables defined in an outer scope) would be deleted from the outer scope.
3895
Gregory P. Smith0470bab2008-07-22 04:46:32 +00003896- Issue #2620: Overflow checking when allocating or reallocating memory
3897 was not always being done properly in some python types and extension
3898 modules. PyMem_MALLOC, PyMem_REALLOC, PyMem_NEW and PyMem_RESIZE have
3899 all been updated to perform better checks and places in the code that
3900 would previously leak memory on the error path when such an allocation
3901 failed have been fixed.
3902
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00003903Library
3904-------
3905
Hirokazu Yamamoto838c79f2008-08-20 13:14:07 +00003906- Issue #3612: Added some missing basic types in ctypes.wintypes.
3907
Benjamin Petersone977ad42008-08-20 01:42:01 +00003908- The methods ``is_in_tuple()``, ``is_vararg()``, and ``is_keywordarg()`` of
3909 symtable.Symbol have been deprecated for removal in 3.0 and the next release.
3910
Amaury Forgeot d'Arc351ffb82008-08-18 19:23:47 +00003911- Issue #2234: distutils failed for some versions of the cygwin compiler. The
3912 version reported by these tools does not necessarily follow the python
3913 version numbering scheme, so the module is less strict when parsing it.
3914
Nick Coghlanf70385a2008-08-18 12:42:46 +00003915- Issue #2235: Added Py3k warnings for types which will become unhashable
3916 under the stricter __hash__ inheritance rules in 3.0. Several types
3917 which did not meet the rules for hash invariants and were already
3918 unhashable in 3.0 have now been explicitly flagged as unhashable in
3919 2.6 as well (collections.Mapping, collections.Set, unittest.TestSuite,
3920 xml.dom.minidom.NamedNodeMap, numbers.Number, UserList.UserList)
3921
Brett Cannon88f801d2008-08-18 00:46:22 +00003922- Update __all__ for cookielib, csv, os, urllib2, and weakref to include things
3923 imported into the module but exposed as part of the module's API.
3924
Brett Cannon7b96f072008-08-18 00:41:11 +00003925- Remove an unneeded import of abc.ABCMeta from 'inspect'.
3926
Brett Cannon46225e72008-08-18 00:36:52 +00003927- Remove unneeded imports of 'sys' and 'warnings' from 'io'.
3928
Brett Cannon25c9d6a2008-08-17 22:10:11 +00003929- Remove unneeded imports of 'warnings' from shelve, filecmp, and dummy_thread.
3930
Hirokazu Yamamoto41a81eb2008-08-17 13:10:46 +00003931- Issue #3575: Incremental decoder's decode function now takes bytearray
3932 by using 's*' instead of 't#'.
3933
Mark Dickinson3e4caeb2009-02-21 20:27:01 +00003934- Issue #2222: Fixed reference leak when occurred os.rename()
Hirokazu Yamamoto7f30a682008-08-17 09:46:56 +00003935 fails unicode conversion on 2nd parameter. (windows only)
3936
Georg Brandl222e2082010-08-01 22:27:39 +00003937- Issue #2464: urllib2 now supports a malformation in the URL received
Facundo Batista94f243a2008-08-17 03:38:39 +00003938 in a redirect.
3939
Brett Cannonabe423e2008-08-16 21:47:07 +00003940- Silence the DeprecationWarning raised when importing mimetools in
Brett Cannon721b1452008-08-16 22:00:27 +00003941 BaseHTTPServer, cgi (and rfc822), httplib.
Brett Cannonabe423e2008-08-16 21:47:07 +00003942
Facundo Batistaeb90b782008-08-16 14:44:07 +00003943- Issue #2776: fixed small issue when handling an URL with double slash
3944 after a 302 response in the case of not going through a proxy.
3945
Antoine Pitroub90a8be2008-08-15 21:03:21 +00003946- Issue #2676: in the email package, content-type parsing was hanging on
3947 pathological input because of quadratic or exponential behaviour of a
3948 regular expression.
3949
Antoine Pitrou11ec65d2008-08-14 21:04:30 +00003950- Issue #3476: binary buffered reading through the new "io" library is now
3951 thread-safe.
3952
Brett Cannonbf3157b2008-08-14 05:00:03 +00003953- Silence the DeprecationWarning of rfc822 when it is imported by mimetools
3954 since mimetools itself is deprecated. Because modules are cached, all
3955 subsequent imports of rfc822 will not raise a visible DeprecationWarning.
3956
Antoine Pitrou9fcd4b32008-08-11 17:21:36 +00003957- Issue #3134: shutil referenced undefined WindowsError symbol.
3958
Robert Schuppenies14646332008-08-10 11:01:53 +00003959- Issue #1342811: Fix leak in Tkinter.Menu.delete. Commands associated to
3960 menu entries were not deleted.
3961
Brett Cannon83e81842008-08-09 23:30:55 +00003962- Copied the implementation of reduce() to _functools.reduce() to have a
3963 version that did not raise a DeprecationWarning under -3.
3964
Antoine Pitrou76b8bee2008-08-09 17:27:23 +00003965- Issue #3205: When iterating over a BZ2File fails allocating memory, raise
3966 a MemoryError rather than silently stop the iteration.
3967
Guido van Rossum59ce9012008-08-09 14:55:34 +00003968- Issue #3487: sre "bytecode" validator. Passing invalid "re-bytecode"
3969 to _sre.compile() will now be rejected. This should not affect anybody
3970 since the re.compile() function never generates invalid re-bytecode.
3971
Skip Montanaroa032bf42008-08-08 22:52:51 +00003972- Issue #3436: Make csv.DictReader's fieldnames attribute a property so that
3973 upon first access it can be automatically initialized from the csv file if
3974 it wasn't initialized during instantiation.
3975
Brett Cannon3aa2a492008-08-06 22:28:09 +00003976- Issue #2338: Create imp.reload() to help with transitioning to Python 3.0 as
3977 the reload() built-in has been removed.
3978
Brett Cannon7e30b672008-08-04 21:52:25 +00003979- Changed code in the following modules/packages to remove warnings raised

4048-----------------
4049
Georg Brandl3e483f62008-07-16 22:57:41 +00004050- Issue #3156: Fix inconsistent behavior of the bytearray type: all
4051 its methods now allow for items objects that can be converted to
4052 an integer using operator.index().
4053
Mark Dickinson64b7e502008-07-16 09:40:03 +00004054- Issue #3360: Fix incorrect parsing of '020000000000.0', which
4055 produced a ValueError instead of giving the correct float.
4056
Eric Smitha5fa5a22008-07-16 00:11:49 +00004057- Issue #3083: Add alternate (#) formatting for bin, oct, hex output
4058 for str.format(). This adds the prefix 0b, 0o, or 0x, respectively.
4059
Mark Dickinson7103aa42008-07-15 19:08:33 +00004060- Issue #3008: the float type has a new instance method 'float.hex'
4061 and a new class method 'float.fromhex' to convert floating-point
4062 numbers to and from hexadecimal strings, respectively.
4063
Nick Coghlan6d6bd442008-07-15 15:40:22 +00004064- Issue #2235: __hash__ is once again inherited by default. To allow
4065 collections.Hashable to remain meaningful in the presence of the
4066 default hash implementation (object.__hash__), it is now possible
4067 to explicit block inheritance of hash by setting __hash__=None at
4068 the Python level, or tp_hash=PyObject_HashNotImplemented at the C
4069 level.
4070
Nick Coghlanb028f502008-07-13 14:52:36 +00004071- Issue #3221: Issue a RuntimeWarning instead of raising SystemError if
4072 the parent module cannot be found while performing an absolute import.
4073 This means that an incorrectly defined __package__ attribute will
4074 now only prevent relative imports in that module rather than causing
4075 all imports from that module to fail.
4076
Nick Coghlan14ff9942008-07-08 14:21:42 +00004077- Issue #2517: Allow unicode messages in Exceptions again by correctly

4087 another thread's dictionary.
4088
Mark Dickinson1ec2fcd2008-06-20 14:53:43 +00004089- Issue #3004: Minor change to slice.indices(): the start and stop
4090 arguments are now treated identically, making the behaviour easier
4091 to describe and understand. For example, slice(None, -10,
4092 1).indices(9) now returns (0, 0, 1) instead of (0, -1, 1), and
4093 slice(None, 10, -1).indices(10) returns (9, 9, -1) instead of (9,
4094 10, -1).
4095
Georg Brandl278fc502008-07-19 12:46:12 +00004096- Issue #3219: Calling a function with repeated keyword arguments,
4097 f(a=2, a=23), would not cause a syntax error. This was a regression
4098 from 2.4 caused by the switch to the new compiler.

4137 both unnecessary (HTTP allows text content to be sent in several forms) and
Andrew M. Kuchlingcc3f2b12008-07-10 14:43:31 +00004138 wrong because the actual transmitted size could differ from the
Amaury Forgeot d'Arc0f7cddc2008-07-06 21:34:39 +00004139 content-length. The problem had been corrected in the 2.4 branch, but never

Nick Coghlanc060b0e2008-07-02 13:09:19 +00004155- Issue #3190: Pydoc now hides the automatic module attribute __package__ (the

Ronald Oussoren5640ce22008-06-05 12:58:24 +00004546- On MacOS X it is now possible to install the framework in 64-bit
4547 mode or even as a 4-way universal binary (that is, PPC, i386,
Georg Brandl5cc774e2008-06-11 20:28:06 +00004548 PPC64 and x86_64 support in one binary).
Ronald Oussoren5640ce22008-06-05 12:58:24 +00004549
4550 This is controlled by the configure argument ``--with-universal-archs``:
4551
4552 - ``--with-universal-archs=all``: install 4-way universal
4553
4554 - ``--with-universal-archs=32-bit``: install 2-way universal, 32-bit (the default)
4555
4556 - ``--with-universal-archs=64-bit``: install 2-way universal, 64-bit
4557
4558 This option should be used in combination with ``--enable-universalsdk=``.
4559
4560 NOTE: 64-bit and 4-way builds are only suppported on Mac OS X 10.5 (or later).

4565
Georg Brandl74a1dea2008-05-28 11:21:39 +00004566- Add ``PyType_Modified()`` as a public API to clear the type cache.
4567
4568- The PyBytes functions have been renamed to PyByteArray.
Christian Heimes7a990612008-05-26 13:15:11 +00004569
4570- The PyString functions have been renamed to PyBytes. A batch of
4571 defines were added so that the linker still sees the original
4572 PyString names.

Georg Brandl3ee81df2008-05-17 18:14:43 +00004610- Issue #1631171: Re-implement the 'warnings' module in C (the
4611 original Python code has been kept as backup). This will allow for
4612 using the 'warning's machinery in such places as the parser where
4613 use of pure Python code is not possible. Both the ``showarning()``
4614 and ``formatwarning()`` gain an optional 'line' argument which is
4615 not called by default for backwards-compatibility reasons. Setting
4616 ``warnings.showwarning()`` to an implementation that lacks support
4617 for the ``line`` argument will raise a DeprecationWarning.

Georg Brandl3ee81df2008-05-17 18:14:43 +00004659- Issue #2513: distutils on Windows is now capable of cross-compiling
Mark Hammond495cf992008-04-07 01:53:39 +00004660 extension modules between 32 and 64 bit platforms. See the distutls

Georg Brandl3ee81df2008-05-17 18:14:43 +00004680- Issue #2550: The approach used by client/server code for obtaining
4681 ports to listen on in network-oriented tests has been refined in an
4682 effort to facilitate running multiple instances of the entire
4683 regression test suite in parallel without issue.
4684 test_support.bind_port() has been fixed such that it will always
4685 return a unique port -- which wasn't always the case with the
4686 previous implementation, especially if socket options had been set
4687 that affected address reuse (i.e. SO_REUSEADDR, SO_REUSEPORT). The
4688 new implementation of bind_port() will actually raise an exception
4689 if it is passed an AF_INET/SOCK_STREAM socket with either the
4690 SO_REUSEADDR or SO_REUSEPORT socket option set. Furthermore, if
4691 available, bind_port() will set the SO_EXCLUSIVEADDRUSE option on
4692 the socket it's been passed. This currently only applies to
4693 Windows. This option prevents any other sockets from binding to the
4694 host/port we've bound to, thus removing the possibility of the
4695 'non-deterministic' behaviour, as Microsoft puts it, that occurs
4696 when a second SOCK_STREAM socket binds and accepts to a host/port
4697 that's already been bound by another socket. The optional preferred
4698 port parameter to bind_port() has been removed. Under no
4699 circumstances should tests be hard coding ports!
4700
4701 test_support.find_unused_port() has also been introduced, which will
4702 pass a temporary socket object to bind_port() in order to obtain an
4703 unused port. The temporary socket object is then closed and
4704 deleted, and the port is returned. This method should only be used
4705 for obtaining an unused port in order to pass to an external program
4706 (i.e. the -accept [port] argument to openssl's s_server mode) or as
4707 a parameter to a server-oriented class that doesn't give you direct
4708 access to the underlying socket used.
4709
4710 Finally, test_support.HOST has been introduced, which should be used
4711 for the host argument of any relevant socket calls (i.e. bind and
4712 connect).
Trent Nelsone41b0062008-04-08 23:47:30 +00004713
4714 The following tests were updated to following the new conventions:
Georg Brandl3ee81df2008-05-17 18:14:43 +00004715 test_socket, test_smtplib, test_asyncore, test_ssl, test_httplib,
Trent Nelsone41b0062008-04-08 23:47:30 +00004716 test_poplib, test_ftplib, test_telnetlib, test_socketserver,
4717 test_asynchat and test_socket_ssl.
4718
Georg Brandl3ee81df2008-05-17 18:14:43 +00004719 It is now possible for multiple instances of the regression test
4720 suite to run in parallel without issue.

Eric Smitha73fbe72008-02-23 03:09:44 +00004999- Added the future_builtins module, which contains hex() and oct().
5000 These are the PEP 3127 version of these functions, designed to be
5001 compatible with the hex() and oct() builtins from Python 3.0. They
5002 differ slightly in their output formats from the existing, unchanged
5003 Python 2.6 builtins. The expected usage of the future_builtins
5004 module is:
5005 from future_builtins import hex, oct
5006
Eric Smith7ef40bf2008-02-20 23:34:22 +00005007- Issue #1600: Modifed PyOS_ascii_formatd to use at most 2 digit
5008 exponents for exponents with absolute value < 100. Follows C99
5009 standard. This is a change on Windows, which would use 3 digits.
5010 Also, added 'n' to the formats that PyOS_ascii_formatd understands,
5011 so that any alterations it does to the resulting string will be
5012 available in stringlib/formatter.h (for float.__format__).
5013
Eric Smith5a3c1352008-02-19 13:21:56 +00005014- Implemented PEP 3101, Advanced String Formatting. This adds a new
5015 builtin format(); a format() method for str and unicode; a
5016 __format__() method to object, str, unicode, int, long, float, and
5017 datetime; the class string.Formatter; and the C API
5018 PyObject_Format().
5019
Georg Brandl3ee81df2008-05-17 18:14:43 +00005020- Fixed several potential crashes, all caused by specially crafted
5021 __del__ methods exploiting objects in temporarily inconsistent
5022 state.

5033 memory to the OS earlier.
Christian Heimes3b718a72008-02-14 12:47:33 +00005034
Georg Brandl3ee81df2008-05-17 18:14:43 +00005035- Issue #2045: Fix an infinite recursion triggered when printing a
5036 subclass of collections.defaultdict, if its default_factory is set
5037 to a bound method.
Amaury Forgeot d'Arcb01aa432008-02-08 00:56:02 +00005038
Christian Heimesf75dbef2008-02-08 00:11:31 +00005039- Fixed a minor memory leak in dictobject.c. The content of the free
5040 list was not freed on interpreter shutdown.
5041
Georg Brandl21e99f42010-03-07 15:23:59 +00005042- Limit free list of method and built-in function objects to 256

5046 functions ``PyInt_CompactFreeList`` and ``PyFloat_CompactFreeList``
Christian Heimes422051a2008-02-04 18:00:12 +00005047 to compact the internal free lists of pre-allocted ints and floats.
5048
Georg Brandl3ee81df2008-05-17 18:14:43 +00005049- Issue #1983: Fixed return type of fork(), fork1() and forkpty()
5050 calls. Python expected the return type int but the fork familie
5051 returns pi_t.

Georg Brandl3ee81df2008-05-17 18:14:43 +00005062- Added ``PyType_ClearCache()`` and ``sys._clear_type_cache`` to clear
5063 the internal lookup cache for ref leak tests.
Christian Heimes908caac2008-01-27 23:34:59 +00005064
Georg Brandl3ee81df2008-05-17 18:14:43 +00005065- Patch #1473257: generator objects gain a gi_code attribute. This is
5066 the same object as the func_code attribute of the function that
5067 produced the generator.
Georg Brandl0cdf9a32008-01-26 14:14:20 +00005068
Georg Brandl3ee81df2008-05-17 18:14:43 +00005069- Issue #1920: "while 0" statements were completely removed by the
5070 compiler, even in the presence of an "else" clause, which is
5071 supposed to be run when the condition is false. Now the compiler
5072 correctly emits bytecode for the "else" suite.
Amaury Forgeot d'Arc31eaafe2008-01-24 22:59:25 +00005073
Guido van Rossumeead05f2008-01-24 18:21:02 +00005074- A few crashers fixed: weakref_in_del.py (issue #1377858);
5075 loosing_dict_ref.py (issue #1303614, test67.py);
5076 borrowed_ref_[34].py (not in tracker).
5077
Vinay Sajipd7cf32e2008-01-24 12:43:33 +00005078- Issue #1069410: The "can't load dll" message box on Windows is
Christian Heimesb2302ba2008-01-23 17:15:06 +00005079 suppressed while an extension is loaded by calling SetErrorMode in
5080 dynload_win.c. The error is still reported properly.
5081
Georg Brandl3ee81df2008-05-17 18:14:43 +00005082- Issue #1915: Python compiles with --enable-unicode=no again. However
Christian Heimes082c9b02008-01-23 14:20:50 +00005083 several extension methods and modules do not work without unicode
5084 support.
5085
Georg Brandl26543b12008-01-21 18:36:51 +00005086- Issue #1882: when compiling code from a string, encoding cookies in the
5087 second line of code were not always recognized correctly.
5088
Georg Brandl14404b62008-01-19 19:27:05 +00005089- Issue #1679: "0x" was taken as a valid integer literal.
5090
Georg Brandl6caad7d2008-01-26 14:19:22 +00005091- Issue #1865: ``bytes`` as an alias for ``str`` and b"" as an alias "" were
Christian Heimes288e89a2008-01-18 18:24:07 +00005092 added.
5093
Christian Heimesc94e2b52008-01-14 04:13:37 +00005094- sys.float_info / PyFloat_GetInfo: The floating point information
5095 object was converted from a dict to a specialized structseq object.
5096
Georg Brandl3ee81df2008-05-17 18:14:43 +00005097- Patch #1816: Added sys.flags structseq. It exposes the status of
5098 most command line arguments and PYTHON* environment variables.
Christian Heimesf31b69f2008-01-14 03:42:48 +00005099
Georg Brandl3ee81df2008-05-17 18:14:43 +00005100- Objects/structseq.c: Implemented new structseq representation. The
5101 patch makes structseqs (e.g. the return value of os.stat) more
5102 readable.
Christian Heimes9c201962008-01-14 03:33:52 +00005103
Georg Brandl3ee81df2008-05-17 18:14:43 +00005104- Patch #1700288: added a type attribute cache that caches method
5105 accesses, resulting in speedups in heavily object-oriented code.
Amaury Forgeot d'Arce4c270c2008-01-14 00:29:41 +00005106
Neal Norwitz3fc15b82008-01-10 05:42:58 +00005107- Bug #1776: __import__() no longer accepts filenames on any platform.
5108 The first parameter to __import__() must be a valid module name.
Christian Heimes3403f152008-01-09 19:56:33 +00005109
Georg Brandlaed6c662008-01-07 17:25:53 +00005110- Patch #1668: renamed THREADDEBUG envvar to PYTHONTHREADDEBUG.
5111
Georg Brandl3ee81df2008-05-17 18:14:43 +00005112- Patch #602345: Add -B command line option, PYTHONDONTWRITEBYTECODE
5113 envvar and sys.dont_write_bytecode attribute. All these can be set
5114 to forbid Python to attempt to write compiled bytecode files.
Georg Brandl2da0fce2008-01-07 17:09:35 +00005115
Georg Brandl3ee81df2008-05-17 18:14:43 +00005116- Improve some exception messages when Windows fails to load an
5117 extension module. Now we get for example '%1 is not a valid Win32
5118 application' instead of 'error code 193'.
Amaury Forgeot d'Arce0b76952008-01-04 02:04:15 +00005119
Georg Brandl3ee81df2008-05-17 18:14:43 +00005120- Bug #1481296: Fixed long(float('nan')) != 0L.

Georg Brandl3ee81df2008-05-17 18:14:43 +00005122- Issue #1640: Added math.isinf(x), math.isnan(x) and math.copysign(x,
5123 y) functions.
Christian Heimese2ca4242008-01-03 20:23:15 +00005124
Christian Heimes0a8143f2007-12-18 23:22:54 +00005125- Issue #1635: Platform independent creation and representation of NaN
Georg Brandl3ee81df2008-05-17 18:14:43 +00005126 and INF. float("nan"), float("inf") and float("-inf") now work on
5127 every platform with IEEE 754 semantics.
Christian Heimes0a8143f2007-12-18 23:22:54 +00005128
Georg Brandl3ee81df2008-05-17 18:14:43 +00005129- Compiler now generates simpler and faster code for dictionary
5130 literals. The oparg for BUILD_MAP now indicates an estimated
5131 dictionary size. There is a new opcode, STORE_MAP, for adding
5132 entries to the dictionary.
Raymond Hettingerfd7ed402007-12-18 21:24:09 +00005133
Georg Brandl3ee81df2008-05-17 18:14:43 +00005134- Issue #1638: %zd configure test fails on Linux.
Christian Heimesdb3d6cb2007-12-16 21:39:43 +00005135
Georg Brandl3ee81df2008-05-17 18:14:43 +00005136- Issue #1620: New property decorator syntax was modifying the
5137 decorator in place instead of creating a new decorator object.
Christian Heimes90e10e72007-12-14 02:35:23 +00005138
Georg Brandl3ee81df2008-05-17 18:14:43 +00005139- Issue #1538: Avoid copying string in split/rsplit if the split char
5140 is not found.
Skip Montanaro26015492007-12-08 15:33:24 +00005141
Andrew M. Kuchling395fe442007-12-05 13:27:20 +00005142- Issue #1553: An erroneous __length_hint__ can make list() raise a
Christian Heimes7cc1c6f2007-12-05 12:52:34 +00005143 SystemError.
5144
Nick Coghlanef01d822007-12-03 12:55:17 +00005145- PEP 366: Allow explicit relative imports when executing modules
5146 inside packages with the -m switch via a new module level
5147 __package__ attribute.
5148
Georg Brandl3ee81df2008-05-17 18:14:43 +00005149- Issue #1402: Fix a crash on exit, when another thread is still
5150 running, and if the deallocation of its frames somehow calls the
5151 PyGILState_Ensure() / PyGILState_Release() functions.
Amaury Forgeot d'Arcbe49a902007-11-30 20:37:22 +00005152

Amaury Forgeot d'Arcce7d10c2007-11-24 13:44:17 +00005156 attribute of an empty cell object.
5157
Georg Brandl3ee81df2008-05-17 18:14:43 +00005158- Issue #1460: The utf-7 incremental decoder did not accept truncated
5159 input. It now correctly saves its state between chunks of data.
Amaury Forgeot d'Arcf57375a2007-11-21 01:38:26 +00005160
Georg Brandl3ee81df2008-05-17 18:14:43 +00005161- Patch #1739468: Directories and zipfiles containing a __main__.py
5162 file can now be directly executed by passing their name to the
5163 interpreter. The directory/zipfile is automatically inserted as the
5164 first entry in sys.path.
Nick Coghlan327a39b2007-11-18 11:56:28 +00005165
Georg Brandl3ee81df2008-05-17 18:14:43 +00005166- Issue #1265: Fix a problem with sys.settrace, if the tracing
5167 function uses a generator expression when at the same time the
5168 executed code is closing a paused generator.
Amaury Forgeot d'Arc0d75f092007-11-13 21:54:28 +00005169
Raymond Hettinger1760c8a2007-11-08 02:52:43 +00005170- sets and frozensets now have an isdisjoint() method.
5171
Raymond Hettinger3f8caa32007-10-24 01:28:33 +00005172- optimize the performance of builtin.sum().
5173
Neal Norwitz44f326e2007-10-05 05:29:17 +00005174- Fix warnings found by the new version of the Coverity checker.
5175
Georg Brandl21e99f42010-03-07 15:23:59 +00005176- The enumerate() built-in function is no longer bounded to sequences
Georg Brandl3ee81df2008-05-17 18:14:43 +00005177 smaller than LONG_MAX. Formerly, it raised an OverflowError. Now,
5178 automatically shifts from ints to longs.
Raymond Hettinger8f669372007-10-03 21:18:11 +00005179
Georg Brandl3ee81df2008-05-17 18:14:43 +00005180- Issue #1686386: Tuple's tp_repr did not take into account the
5181 possibility of having a self-referential tuple, which is possible
5182 from C code. Nor did object's tp_str consider that a type's tp_str
5183 could do something that could lead to an inifinite recursion.
5184 Py_ReprEnter() and Py_EnterRecursiveCall(), respectively, fixed the
5185 issues.
Brett Cannon0b14f242007-09-30 19:45:10 +00005186
Georg Brandl3ee81df2008-05-17 18:14:43 +00005187- Issue #1164: It was possible to trigger deadlock when using the
5188 'print' statement to write to a file since the GIL was not released
5189 as needed. Now PyObject_Print() does the right thing along with
5190 various tp_print implementations of the built-in types and those in
5191 the collections module.
Brett Cannon01531592007-09-17 03:28:34 +00005192
Georg Brandl3ee81df2008-05-17 18:14:43 +00005193- Issue #1147: Exceptions were directly allowing string exceptions in
5194 their throw() method even though string exceptions no longer
5195 allowed.
Brett Cannon4c20bc42007-09-11 21:02:28 +00005196
Georg Brandl3ee81df2008-05-17 18:14:43 +00005197- Issue #1096: Prevent a segfault from getting the repr of a very
5198 deeply nested list by using the recursion counter.
Brett Cannona0c05512007-09-10 21:38:27 +00005199
Brett Cannon1e534b52007-09-07 04:18:30 +00005200- Issue #1202533: Fix infinite recursion calls triggered by calls to
Georg Brandl3ee81df2008-05-17 18:14:43 +00005201 PyObject_Call() never calling back out to Python code to trigger
5202 recursion depth updates/checks. Required the creation of a static
5203 RuntimeError instance in case normalizing an exception put the
5204 recursion check value past its limit. Fixes crashers
5205 infinite_rec_(1|2|4|5).py.
Brett Cannon1e534b52007-09-07 04:18:30 +00005206
Georg Brandl3ee81df2008-05-17 18:14:43 +00005207- Patch #1031213: Decode source line in SyntaxErrors back to its
5208 original source encoding.

5211 with %G.
5212
Georg Brandl3ee81df2008-05-17 18:14:43 +00005213- Prevent expandtabs() on string and unicode objects from causing a
5214 segfault when a large width is passed on 32-bit platforms.
Neal Norwitz7dbd2a32007-06-09 03:36:34 +00005215

Georg Brandla5ea6892007-06-01 11:33:33 +00005219
Neal Norwitz0ac60192007-05-27 04:08:54 +00005220- Add new attribute names for function objects. All the func_* become
Georg Brandl3ee81df2008-05-17 18:14:43 +00005221 __*__ attributes. (Some already existed, e.g., __doc__ and
5222 __name__.)
Neal Norwitz0ac60192007-05-27 04:08:54 +00005223
Neal Norwitz8b2bfbc2007-05-23 06:35:32 +00005224- Add -3 option to the interpreter to warn about features that are
5225 deprecated and will be changed/removed in Python 3.0.
5226
Georg Brandl2134e752007-05-21 20:34:16 +00005227- Patch #1686487: you can now pass any mapping after '**' in function
5228 calls.
5229
Collin Winter62903052007-05-18 23:11:24 +00005230- except clauses may now be spelled either "except E, target:" or
Georg Brandl3ee81df2008-05-17 18:14:43 +00005231 "except E as target:". This is to provide forwards compatibility
5232 with Python 3.0.
Collin Winter62903052007-05-18 23:11:24 +00005233
Brett Cannon229cee22007-05-05 01:34:02 +00005234- Deprecate BaseException.message as per PEP 352.
5235
Georg Brandl3ee81df2008-05-17 18:14:43 +00005236- Issue #1303614: don't expose object's __dict__ when the dict is
Georg Brandl21e99f42010-03-07 15:23:59 +00005237 inherited from a built-in base.
Armin Rigo9790a272007-05-02 19:23:31 +00005238
Vinay Sajip8549ce32007-05-06 17:53:37 +00005239- When __slots__ are set to a unicode string, make it work the same as
Neal Norwitzcbd9ee62007-04-14 05:25:50 +00005240 setting a plain string, ie don't expand to single letter identifiers.
5241
Raymond Hettinger13936692007-04-11 18:40:58 +00005242- Request #1191699: Slices can now be pickled.
5243
Raymond Hettinger4db5fe92007-04-12 04:10:00 +00005244- Request #1193128: str.translate() now allows a None argument for
5245 translations that only remove characters without re-mapping the
5246 remaining characters.
5247
Georg Brandl5cb76c12007-03-21 09:00:39 +00005248- Patch #1682205: a TypeError while unpacking an iterable is no longer
5249 masked by a generic one with the message "unpack non-sequence".
5250
Neal Norwitzaa754b72007-03-21 06:39:48 +00005251- Remove unused file Python/fmod.c.
5252
Guido van Rossum143b5642007-03-23 04:58:42 +00005253- Bug #1683368: The object.__init__() and object.__new__() methods are
5254 now stricter in rejecting excess arguments. The only time when
5255 either allows excess arguments is when it is not overridden and the
5256 other one is. For backwards compatibility, when both are
5257 overridden, it is a deprecation warning (for now; maybe a Py3k
Guido van Rossum234b1ff2007-03-23 19:39:01 +00005258 warning later). Also, type.__init__() insists on the same signature
5259 as supported by type.__new__().
Guido van Rossum143b5642007-03-23 04:58:42 +00005260
Georg Brandl3ee81df2008-05-17 18:14:43 +00005261- Patch #1675423: PyComplex_AsCComplex() now tries to convert an
5262 object to complex using its __complex__() method before falling back
5263 to the __float__() method. Therefore, the functions in the cmath
5264 module now can operate on objects that define a __complex__()
5265 method.
Georg Brandl2b869942007-03-17 16:08:45 +00005266
Georg Brandl3ee81df2008-05-17 18:14:43 +00005267- Patch #1623563: allow __class__ assignment for classes with
5268 __slots__. The old and the new class are still required to have the
5269 same slot names.
Žiga Seilnacht6f2d09c2007-03-16 11:59:38 +00005270
Georg Brandl3ee81df2008-05-17 18:14:43 +00005271- Patch #1642547: Fix an error/crash when encountering syntax errors
5272 in complex if statements.

Georg Brandl3ee81df2008-05-17 18:14:43 +00005274- Patch #1462488: Python no longer segfaults when
5275 ``object.__reduce_ex__()`` is called with an object that is faking
5276 its type.
Žiga Seilnacht20f43d32007-03-15 11:44:55 +00005277
Georg Brandl3ee81df2008-05-17 18:14:43 +00005278- Patch #1680015: Don't modify __slots__ tuple if it contains an
5279 unicode name.

Georg Brandl5240d742007-03-13 20:46:32 +00005281- Patch #1444529: the builtin compile() now accepts keyword arguments.
5282
Georg Brandl7b9c5552007-03-12 14:30:05 +00005283- Bug #1678647: write a newline after printing an exception in any
5284 case, even when converting the value to a string failed.
5285
Georg Brandl871f1bc2007-03-12 13:17:36 +00005286- The dir() function has been extended to call the __dir__() method on
Georg Brandl3ee81df2008-05-17 18:14:43 +00005287 its argument, if it exists. If not, it will work like before. This
5288 allows customizing the output of dir() in the presence of a
5289 __getattr__().
Georg Brandl871f1bc2007-03-12 13:17:36 +00005290
Collin Winter276887b2007-03-12 16:11:39 +00005291- Patch #922167: Python no longer segfaults when faced with infinitely
5292 self-recursive reload() calls (as reported by bug #742342).
5293
Georg Brandl3ee81df2008-05-17 18:14:43 +00005294- Patch #1675981: remove unreachable code from ``type.__new__()``
5295 method.
Žiga Seilnacht89032082007-03-11 15:54:54 +00005296
Georg Brandl3ee81df2008-05-17 18:14:43 +00005297- Patch #1491866: change the complex() constructor to allow
5298 parthensized forms. This means complex(repr(x)) now works instead of
5299 raising a ValueError.

5810 ".cpp" too.
5811
Facundo Batistad918a652007-04-24 13:54:38 +00005812- As specified in RFC 2616, an HTTP response like 2xx indicates that
Georg Brandl3ee81df2008-05-17 18:14:43 +00005813 the client's request was successfully received, understood, and
5814 accepted. Now in these cases no error is raised in urllib (issue
5815 #1177) and urllib2.
Facundo Batistad918a652007-04-24 13:54:38 +00005816

Facundo Batistab6a5c9d2007-03-29 18:22:35 +00005823- Added a timeout parameter to the constructor of other protocols
5824 (telnetlib, ftplib, smtplib and poplib). This is second part of the
5825 work started with create_connection() and timeout in httplib, and
5826 closes patch #723312.
5827
Vinay Sajip8549ce32007-05-06 17:53:37 +00005828- Patch #1676823: Added create_connection() to socket.py, which may be
5829 called with a timeout, and use it from httplib (whose HTTPConnection
Facundo Batista70f996b2007-05-21 17:32:32 +00005830 and HTTPSConnection now accept an optional timeout).
Facundo Batista07c78be2007-03-23 18:54:07 +00005831
Martin v. Löwis0af33882007-03-23 13:27:15 +00005832- Bug #978833: Revert r50844, as it broke _socketobject.dup.

Georg Brandl3ee81df2008-05-17 18:14:43 +00005839- Patch #1273829: os.walk() now has a "followlinks" parameter. If set
5840 to True (which is not the default), it visits symlinks pointing to
Georg Brandlcae9f3d2007-03-21 09:10:29 +00005841 directories.
5842

5844 GNOME or KDE browser, depending on whether there is a session of one
5845 of those present. Also, it tries the Windows default browser before
5846 trying Mozilla variants.

5852
Georg Brandlf66b6032007-03-14 08:27:52 +00005853- Bug #767111: fix long-standing bug in urllib which caused an
Georg Brandl3ee81df2008-05-17 18:14:43 +00005854 AttributeError instead of an IOError when the server's response
5855 didn't contain a valid HTTP status line.
Georg Brandlf66b6032007-03-14 08:27:52 +00005856
Georg Brandl3ee81df2008-05-17 18:14:43 +00005857- Patch #957650: "%var%" environment variable references are now
5858 properly expanded in ntpath.expandvars(), also "~user" home
5859 directory references are recognized and handled on Windows.
Georg Brandl03b90d82007-03-13 22:07:36 +00005860
Georg Brandl3ee81df2008-05-17 18:14:43 +00005861- Patch #1429539: pdb now correctly initializes the __main__ module
5862 for the debugged script, which means that imports from __main__ work
Georg Brandlb6ae6aa2007-03-13 21:58:44 +00005863 correctly now.
5864
Georg Brandlbad6f192007-03-13 21:32:56 +00005865- The nonobvious commands.getstatus() function is now deprecated.

5871
Georg Brandl3ee81df2008-05-17 18:14:43 +00005872- Patch #1530482: add pydoc.render_doc() which returns the
5873 documentation for a thing instead of paging it to stdout, which
5874 pydoc.doc() does.
Georg Brandl8441f152007-03-13 20:02:57 +00005875
Georg Brandl3ee81df2008-05-17 18:14:43 +00005876- Patch #1533909: the timeit module now accepts callables in addition

5882 parameter which can be set to False to prevent the default
5883 delete-on-close behavior.
Georg Brandl35ef9c12007-03-13 18:31:49 +00005884
Georg Brandl9e6b4702007-03-13 18:15:41 +00005885- Patch #1581073: add a flag to textwrap that prevents the dropping of
5886 whitespace while wrapping.
5887
Georg Brandl92a6bae2007-03-13 17:43:32 +00005888- Patch #1603688: ConfigParser.SafeConfigParser now checks values that
Georg Brandl3ee81df2008-05-17 18:14:43 +00005889 are set for invalid interpolation sequences that would lead to
5890 errors on reading back those values.
Georg Brandl92a6bae2007-03-13 17:43:32 +00005891

5904
Georg Brandl94fe3f52007-03-13 09:32:11 +00005905- Patch #1635454: the csv.DictWriter class now includes the offending
Georg Brandl3ee81df2008-05-17 18:14:43 +00005906 field names in its exception message if you try to write a record
5907 with a dictionary containing fields not in the CSV field names list.

Collin Winter22c42ba2007-03-10 02:51:26 +00005925
Andrew M. Kuchlinge45a77a2008-01-19 16:26:13 +00005926- Patch #742598: Add .timeout attribute to SocketServer that calls

5933 returned string up to the first NUL character.
5934

5944
Georg Brandl3ee81df2008-05-17 18:14:43 +00005945- unittest now verifies more of its assumptions. In particular,
5946 TestCase and TestSuite subclasses (not instances) are no longer
5947 accepted in TestSuite.addTest(). This should cause no
5948 incompatibility since it never made sense with ordinary subclasses
5949 -- the failure just occurred later, with a more cumbersome
5950 exception.
Georg Brandl9caadf82007-03-08 18:37:31 +00005951

5959 given a unicode argument and os.listdir() returns unicode filenames.
5960
Georg Brandl3ee81df2008-05-17 18:14:43 +00005961- Patch #1673619: setup.py identifies extension modules it doesn't

5963 build.

Georg Brandl3ee81df2008-05-17 18:14:43 +00006339 time so that opening a database previously created with the DB_DUP
6340 or DB_DUPSORT flag set will keep the proper behavior on subsequent
6341 opens. Specifically: dictionary assignment to a DB object will
6342 replace all values for a given key when the database allows
6343 duplicate values. DB users should use DB.put(k, v) when they want
6344 to store duplicates; not DB[k] = v.

6351 characters with ASCII value less than 32. Also, it correctly quotes
6352 dots only if they occur on a single line, as opposed to the previous
6353 behavior of quoting dots if they are the second character of any
6354 line.
