709
Raymond Hettinger20397532010-09-12 02:11:45 +0000710- Issue #9825: removed __del__ from the definition of collections.OrderedDict.
711 This prevents user-created self-referencing ordered dictionaries from
712 becoming permanently uncollectable GC garbage. The downside is that
713 removing __del__ means that the internal doubly-linked list has to wait for
714 GC collection rather than freeing memory immediately when the refcnt drops
715 to zero.
716
Raymond Hettingerffd2a422010-09-10 10:47:22 +0000717- Issue #9816: random.Random.jumpahead(n) did not produce a sufficiently

722 would swallow the exception and raise a new one, making it impossible
723 to fetch the original errno, or to filter timeout errors. Now the
724 original error is re-raised.
725
Antoine Pitrouf4f61712010-09-07 16:34:47 +0000726- Issue #9758: When fcntl.ioctl() was called with mutable_flag set to True,

Daniel Stutzbach66c981b2010-08-31 20:29:39 +0000736- Issue #808164: Fixed socket.close to avoid references to globals, to

745
R. David Murray7c4bf552010-08-25 01:45:57 +0000746- Issue #1194222: email.utils.parsedate now returns RFC2822 compliant four
747 character years even if the message contains RFC822 two character years.
748
Daniel Stutzbach91287322010-08-24 21:09:30 +0000749- Issue #8750: Fixed MutableSet's methods to correctly handle

762
Antoine Pitrou3ebaed62010-08-21 19:17:25 +0000763- Issue #9617: Signals received during a low-level write operation aren't
764 ignored by the buffered IO layer anymore.
765
Benjamin Peterson52c36052010-08-21 03:03:22 +0000766- Issue #2521: Use weakrefs on for caching in the abc module, so that classes
767 are not held onto after they are deleted elsewhere.
768
Raymond Hettingera54b2da2010-08-17 19:03:06 +0000769- Issue #9626: the view methods for collections.OrderedDict() were returning
770 the unordered versions inherited from dict. Those methods are now
771 overridden to provide ordered views.
772

774 comment indicating they are generated. Manually maintained MANIFESTs
775 without this marker will not be overwritten or removed.
776
Antoine Pitroue1436d12010-08-12 15:25:51 +0000777- Issue #7467: when reading a file from a ZIP archive, its CRC is checked

779 case in Python 2.5 and earlier).
780
Antoine Pitroucb4f47c2010-08-11 13:40:17 +0000781- Issue #9550: a BufferedReader could issue an additional read when the
782 original read request had been satisfied, which could block indefinitely
783 when the underlying raw IO channel was e.g. a socket. Report and original
784 patch by Jason V. Miller.
785

1190 (2**53+1 == complex(2**53) == 2**53), breaking transivity of equality.
1191 (2) The comparison raised an OverflowError for large integers, leading

1436 started running. This also fixes the occasional freezes witnessed in
1437 test_httpservers.

Antoine Pitroufc69af12010-04-24 20:04:58 +00001439- Issue #5103: SSL handshake would ignore the socket timeout and block
1440 indefinitely if the other end didn't respond.
1441
Georg Brandlfee0f442010-05-22 21:26:21 +00001442- The do_handshake() method of SSL objects now adjusts the blocking mode of the
1443 SSL structure if necessary (as other methods already do).

Georg Brandlfee0f442010-05-22 21:26:21 +00001453- Issue #8451: Syslog module now uses basename(sys.argv[0]) instead of the
1454 string "python" as the *ident*. openlog() arguments are all optional and
1455 keywords.

Philip Jenveyaebbaeb2010-04-06 23:24:45 +00001560- Issue #7301: Add environment variable $PYTHONWARNINGS.
1561
Benjamin Peterson3a1dfa22010-04-06 21:50:00 +00001562- Issue #8329: Don't return the same lists from select.select when no fds are
1563 changed.
1564
Georg Brandlfee0f442010-05-22 21:26:21 +00001565- Issue #8259: ``1L << (2**31)`` no longer produces an 'outrageous shift error'
Mark Dickinson82791672010-04-06 16:47:55 +00001566 on 64-bit machines. The shift count for either left or right shift is
1567 permitted to be up to sys.maxsize.

Georg Brandlfee0f442010-05-22 21:26:21 +00001575- Issue #7994: Issue a PendingDeprecationWarning if object.__format__ is called
1576 with a non-empty format string. This is an effort to future-proof user
1577 code. If a derived class does not currently implement __format__ but later
1578 adds its own __format__, it would most likely break user code that had
Antoine Pitrou01a196a2011-01-02 20:05:11 +00001579 supplied a format string. This will be changed to a DeprecationWarning in
Georg Brandlfee0f442010-05-22 21:26:21 +00001580 Python 3.3 and it will be an error in Python 3.4.

Georg Brandlfee0f442010-05-22 21:26:21 +00001630- Issue #7279: Comparisons involving a Decimal signaling NaN now signal
1631 InvalidOperation instead of returning False. (Comparisons involving a quiet
1632 NaN are unchanged.) Also, Decimal quiet NaNs are now hashable; Decimal
1633 signaling NaNs remain unhashable.
Mark Dickinsone096e822010-04-02 10:17:07 +00001634
Georg Brandlfee0f442010-05-22 21:26:21 +00001635- Issue #2531: Comparison operations between floats and Decimal instances now
1636 return a result based on the numeric values of the operands; previously they
1637 returned an arbitrary result based on the relative ordering of id(float) and
1638 id(Decimal).

Georg Brandlfee0f442010-05-22 21:26:21 +00001652- Comparisons using one of <, <=, >, >= between a complex instance and a
1653 Fractions instance now raise TypeError instead of returning True/False. This
1654 makes Fraction <=> complex comparisons consistent with int <=> complex, float
1655 <=> complex, and complex <=> complex comparisons.

Georg Brandlba83f822010-03-14 09:50:54 +00002073 file position when calling `truncate()`. It would previously change the file
2074 position to the given argument, which goes against the tradition of
Antoine Pitrouf3fa0742010-01-31 22:26:04 +00002075 ftruncate() and other truncation APIs. Patch by Pascal Chambon.

2171
Georg Brandlba83f822010-03-14 09:50:54 +00002172- The ``__complex__()`` method is now looked up on the class of instances to
2173 make it consistent with other special methods.

2177
Mark Dickinson1b34d252010-01-01 17:27:30 +00002178- Issue #5080: A number of functions and methods previously produced a
Georg Brandlba83f822010-03-14 09:50:54 +00002179 DeprecationWarning when passed a float argument where an integer was expected.
2180 These functions and methods now raise TypeError instead. The majority of the
2181 effects of this change are in the extension modules, but some core functions
2182 and methods are affected: notably the 'chr', 'range' and 'xrange' builtins,
2183 and many unicode/str methods.

2195
Georg Brandlba83f822010-03-14 09:50:54 +00002196- Issue #1811: Improve accuracy and cross-platform consistency for true division
2197 of integers: the result of a/b is now correctly rounded for ints a and b (at
2198 least on IEEE 754 platforms), and in particular does not depend on the
2199 internal representation of a long.

2207
Georg Brandlba83f822010-03-14 09:50:54 +00002208 These executables now work properly with the arch(1) command: ``arch -ppc

Georg Brandlba83f822010-03-14 09:50:54 +00002381 The conversions use a Python-adapted version of David Gay's well-known dtoa.c,

2383 supported on Windows, and on Unix-like platforms using gcc, icc or suncc as
2384 the C compiler. There may be a small number of platforms on which correct
2385 operation of this code cannot be guaranteed, so the code is not used: notably,
2386 this applies to platforms where the C double format is not IEEE 754 binary64,
2387 and to platforms on x86 hardware where the x87 FPU is set to 64-bit precision
2388 and Python's configure script is unable to determine how to change the FPU
2389 precision. On these platforms conversions use the platform strtod and dtoa,
2390 as before.

Georg Brandlba83f822010-03-14 09:50:54 +00002392- Issue #7117: Backport round implementation from Python 3.x. ``round()`` now
2393 uses the correctly-rounded string <-> float conversions described above (when
2394 available), and so produces correctly rounded results that will display nicely
2395 under the float repr. There are two related small changes: (1) round now
2396 accepts any class with an ``__index__()`` method for its second argument (but
2397 no longer accepts floats for the second argument), and (2) an excessively
2398 large second integer argument (e.g., ``round(1.234, 10**100)``) no longer
2399 raises an exception.

Georg Brandlba83f822010-03-14 09:50:54 +00003976 - Packing a float now always gives a Deprecation Warning. Previously it
3977 only warned for 'I', 'L', '*B', '*H', '*I', '*L'.
Mark Dickinson463dc4b2009-07-05 10:01:24 +00003978
Georg Brandlba83f822010-03-14 09:50:54 +00003979 - If x is not an int, long or float, then packing x will always result in
3980 struct.error. Previously an x with an __int__ method could be packed by
3981 'b', 'B', 'h', 'H', 'i', 'l', '*b', '*h' ,'*i', '*l', and an x with a
3982 __long__ method could be packed by 'q', 'Q', '*q', '*Q'; for x with
3983 neither __int__ nor __long__, TypeError used to be raised (with a
3984 confusing error message) for 'I', 'L', '*B', '*H', '*I', '*L', and
3985 struct.error in other cases.
Mark Dickinson463dc4b2009-07-05 10:01:24 +00003986
Georg Brandlba83f822010-03-14 09:50:54 +00003987 Note: as of Python 2.7 beta 1, the above is out of date. In 2.7 beta 1, any
3988 argument with an __int__ method can be packed, but use of this feature
3989 triggers a DeprecationWarning.

Amaury Forgeot d'Arc05e34492008-09-10 22:04:45 +00004182- Issue #3743: In a few places, PY_FORMAT_SIZE_T was incorrectly used with
4183 PyString_FromFormat or PyErr_Format to display size_t values. The macro
4184 PY_FORMAT_SIZE_T is designed to select the correct format for the OS
4185 ``printf`` function, whereas PyString_FromFormat has an independent
4186 implementation and uses "%zd" on all platforms for size_t values.
4187 This makes a difference on win64, where ``printf`` needs "%Id" to display

4194 object; previously an int would be returned for small values. the __long__
4195 method is allowed to return either an int or a long, but the behaviour of

4212 type object.

Nick Coghland2e09382008-09-11 12:11:06 +00004256- Issue #3781: Clean up the API for warnings.catch_warnings() by having it
Brett Cannon672237d2008-09-09 00:49:16 +00004257 return a list or None rather than a custom object.
4258
Benjamin Peterson6ac7d7c2008-09-06 19:28:11 +00004259- Issue #1638033: Cookie.Morsel gained the httponly attribute.

Brett Cannon1eaf0742008-09-02 01:25:16 +00004283 warnings.catch_warnings() along with some API cleanup. Expanding the tests
4284 for catch_warnings() also led to an improvement in the raising of a
4285 DeprecationWarning related to warnings.warn_explicit().
4286
Benjamin Peterson973e6c22008-09-01 23:12:58 +00004287- The deprecation warnings for the old camelCase threading API were removed.

4309
Amaury Forgeot d'Arc293924b2008-09-02 23:19:56 +00004310- Issue #2975: When compiling several extension modules with Visual Studio 2008
4311 from the same python interpreter, some environment variables would grow
4312 without limit.
4313
Benjamin Peterson37346b22008-08-23 20:27:43 +00004314- Issue #3643: Added a few more checks to _testcapi to prevent segfaults by
4315 exploitation of poor argument checking.
4316
Gerhard Häringef2276b2008-09-12 13:54:06 +00004317- sqlite3: Changed docstring of iterdump() to mark method as "Non-standard".
4318
Gerhard Häring6e1afcf2008-09-12 18:58:57 +00004319- Issue #3103: Reduced globals symbols used by sqlite3 module and made sure all
4320 remaining ones have "pysqlite_" prefix.
4321
Gerhard Häringe6872eb2008-09-12 22:33:22 +00004322- Issue #3846: Release the GIL during sqlite3_prepare calls. This improves

4330 wrapper for warnings.catch_warnings() that makes it easier to check
4331 that expected warning messages are being reported.
4332

Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00004351What's New in Python 2.6 beta 3?
4352================================
4353
Barry Warsaw07a4a382008-08-21 01:15:08 +00004354*Release date: 20-Aug-2008*
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00004355
4356Core and Builtins
4357-----------------
4358
Guido van Rossumf8402962008-08-20 15:01:50 +00004359- Issue #1878: Remove Py_TPFLAGS_HAVE_VERSION_TAG from
4360 Py_TPFLAGS_DEFAULT when not building the core. This means 3rd party
4361 extensions do not automatically benefit from the class attribute
4362 cache; they will have to explicitly add Py_TPFLAGS_HAVE_VERSION_TAG
4363 to their tp_flags field if they care. This is a backwards
4364 compatibility feature; in 3.0, all types will use the cache by
4365 default.
4366
Benjamin Petersonf647dc12008-08-20 01:27:30 +00004367- Keyword arguments can now follow starred arguments. (``f(a, *args,
4368 keyword=23)`` is now valid syntax.)
4369
Thomas Heller0ad5ae02008-08-19 19:25:04 +00004370- ctypes function pointers that are COM methods have a boolean True
4371 value again.
4372
Martin v. Löwisf91d46a2008-08-12 14:49:50 +00004373- Issue #3139: Make buffer-interface thread-safe wrt. PyArg_ParseTuple,
4374 by denying s# to parse objects that have a releasebuffer procedure,
4375 and introducing s*.
4376
Georg Brandl1e13ea92008-08-11 09:07:59 +00004377- Issue #3537: Fix an assertion failure when an empty but presized dict
4378 object was stored in the freelist.
4379
Mark Dickinsonb6467572008-08-04 21:30:09 +00004380- Issue #1481296: Make long(float('nan')) and int(float('nan')) raise
4381 ValueError consistently across platforms.
4382
Amaury Forgeot d'Arc39fd6722008-07-31 21:28:03 +00004383- Issue #3479: On platforms where sizeof(int) is smaller than sizeof(long)
4384 (64bit Unix, for example), unichr() would truncate its argument and return
4385 u'\x00' for unichr(2**32). Now it properly raises an OverflowError.
4386
Neal Norwitze7d8be82008-07-31 17:17:14 +00004387- Apply security patches from Apple.
4388
Amaury Forgeot d'Arc246daed2008-07-31 00:42:16 +00004389- Issue #2542: Now that issubclass() may call arbitrary code, ensure that
4390 PyErr_ExceptionMatches returns 0 when an exception occurs there.
4391
Antoine Pitrou92f82162008-07-25 22:22:08 +00004392- Issue #1819: function calls with several named parameters are now on
4393 average 35% faster (as measured by pybench).
4394
Amaury Forgeot d'Arce4921fe2008-07-21 22:00:38 +00004395- Issue #2378: An unexpected UnboundLocalError or NameError could appear when
4396 the python debugger steps into a class statement: the free variables (local
4397 variables defined in an outer scope) would be deleted from the outer scope.
4398
Gregory P. Smith0470bab2008-07-22 04:46:32 +00004399- Issue #2620: Overflow checking when allocating or reallocating memory
4400 was not always being done properly in some python types and extension
4401 modules. PyMem_MALLOC, PyMem_REALLOC, PyMem_NEW and PyMem_RESIZE have
4402 all been updated to perform better checks and places in the code that
4403 would previously leak memory on the error path when such an allocation
4404 failed have been fixed.
4405

4407-------
4408
Hirokazu Yamamoto838c79f2008-08-20 13:14:07 +00004409- Issue #3612: Added some missing basic types in ctypes.wintypes.
4410
Benjamin Petersone977ad42008-08-20 01:42:01 +00004411- The methods ``is_in_tuple()``, ``is_vararg()``, and ``is_keywordarg()`` of
4412 symtable.Symbol have been deprecated for removal in 3.0 and the next release.
4413
Amaury Forgeot d'Arc351ffb82008-08-18 19:23:47 +00004414- Issue #2234: distutils failed for some versions of the cygwin compiler. The
4415 version reported by these tools does not necessarily follow the python
4416 version numbering scheme, so the module is less strict when parsing it.
4417
Nick Coghlanf70385a2008-08-18 12:42:46 +00004418- Issue #2235: Added Py3k warnings for types which will become unhashable
4419 under the stricter __hash__ inheritance rules in 3.0. Several types
4420 which did not meet the rules for hash invariants and were already
4421 unhashable in 3.0 have now been explicitly flagged as unhashable in
4422 2.6 as well (collections.Mapping, collections.Set, unittest.TestSuite,
4423 xml.dom.minidom.NamedNodeMap, numbers.Number, UserList.UserList)
4424
Brett Cannon88f801d2008-08-18 00:46:22 +00004425- Update __all__ for cookielib, csv, os, urllib2, and weakref to include things

Brett Cannon25c9d6a2008-08-17 22:10:11 +00004432- Remove unneeded imports of 'warnings' from shelve, filecmp, and dummy_thread.
4433
Hirokazu Yamamoto41a81eb2008-08-17 13:10:46 +00004434- Issue #3575: Incremental decoder's decode function now takes bytearray
4435 by using 's*' instead of 't#'.
4436
Mark Dickinson3e4caeb2009-02-21 20:27:01 +00004437- Issue #2222: Fixed reference leak when occurred os.rename()
Hirokazu Yamamoto7f30a682008-08-17 09:46:56 +00004438 fails unicode conversion on 2nd parameter. (windows only)
4439
Georg Brandl222e2082010-08-01 22:27:39 +00004440- Issue #2464: urllib2 now supports a malformation in the URL received
Facundo Batista94f243a2008-08-17 03:38:39 +00004441 in a redirect.
4442
Brett Cannonabe423e2008-08-16 21:47:07 +00004443- Silence the DeprecationWarning raised when importing mimetools in
Brett Cannon721b1452008-08-16 22:00:27 +00004444 BaseHTTPServer, cgi (and rfc822), httplib.
Brett Cannonabe423e2008-08-16 21:47:07 +00004445
Facundo Batistaeb90b782008-08-16 14:44:07 +00004446- Issue #2776: fixed small issue when handling an URL with double slash
4447 after a 302 response in the case of not going through a proxy.
4448
Antoine Pitroub90a8be2008-08-15 21:03:21 +00004449- Issue #2676: in the email package, content-type parsing was hanging on
4450 pathological input because of quadratic or exponential behaviour of a
4451 regular expression.
4452
Antoine Pitrou11ec65d2008-08-14 21:04:30 +00004453- Issue #3476: binary buffered reading through the new "io" library is now
4454 thread-safe.
4455
Brett Cannonbf3157b2008-08-14 05:00:03 +00004456- Silence the DeprecationWarning of rfc822 when it is imported by mimetools
4457 since mimetools itself is deprecated. Because modules are cached, all
4458 subsequent imports of rfc822 will not raise a visible DeprecationWarning.
4459
Antoine Pitrou9fcd4b32008-08-11 17:21:36 +00004460- Issue #3134: shutil referenced undefined WindowsError symbol.
4461
Robert Schuppenies14646332008-08-10 11:01:53 +00004462- Issue #1342811: Fix leak in Tkinter.Menu.delete. Commands associated to
4463 menu entries were not deleted.
4464
Brett Cannon83e81842008-08-09 23:30:55 +00004465- Copied the implementation of reduce() to _functools.reduce() to have a
4466 version that did not raise a DeprecationWarning under -3.
4467
Antoine Pitrou76b8bee2008-08-09 17:27:23 +00004468- Issue #3205: When iterating over a BZ2File fails allocating memory, raise
4469 a MemoryError rather than silently stop the iteration.
4470
Guido van Rossum59ce9012008-08-09 14:55:34 +00004471- Issue #3487: sre "bytecode" validator. Passing invalid "re-bytecode"
4472 to _sre.compile() will now be rejected. This should not affect anybody
4473 since the re.compile() function never generates invalid re-bytecode.
4474
Skip Montanaroa032bf42008-08-08 22:52:51 +00004475- Issue #3436: Make csv.DictReader's fieldnames attribute a property so that
4476 upon first access it can be automatically initialized from the csv file if
4477 it wasn't initialized during instantiation.
4478
Brett Cannon3aa2a492008-08-06 22:28:09 +00004479- Issue #2338: Create imp.reload() to help with transitioning to Python 3.0 as
4480 the reload() built-in has been removed.
4481
Brett Cannon7e30b672008-08-04 21:52:25 +00004482- Changed code in the following modules/packages to remove warnings raised
Brett Cannonc1b76e42008-08-09 23:06:16 +00004483 while running under the ``-3`` flag: aifc, asynchat, asyncore, bdb, bsddb,

Antoine Pitroude781a42008-08-09 12:43:23 +00004494 asking for a specific length. This problem only affected files opened
4495 using the new "io" module, not the built-in open() function.
Benjamin Peterson01a24322008-07-28 23:35:27 +00004496

Antoine Pitrou5fdfa3e2008-07-25 19:42:26 +00004520- Issue #3394: zipfile.writestr sets external attributes when passed a
4521 file name rather than a ZipInfo instance, so files are extracted with
4522 mode 0600 rather than 000 under Unix.
4523
Gregory P. Smitha36f8fe2008-08-04 00:13:29 +00004524- Issue #1857: subprocess.Popen.poll gained an additional _deadstate keyword
4525 argument in python 2.5, this broke code that subclassed Popen to include its

4537 interaction with the tp_hash slot (added in 2.6b2) are now documented
4538
Nick Coghlan2a0c2b12008-08-04 12:47:17 +00004539- Issue #643841: The language reference now provides more detailed
4540 coverage of the lookup process for special methods. The disclaimers
4541 regarding lack of coverage of new-style classes have also been
4542 removed, since the coverage is now fairly reasonable.

Raymond Hettingere3ae6552008-06-20 04:18:15 +00004545What's New in Python 2.6 beta 2?
4546================================
4547
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00004548*Release date: 17-Jul-2008*

Raymond Hettingere3ae6552008-06-20 04:18:15 +00004550Core and Builtins
4551-----------------
4552
Georg Brandl3e483f62008-07-16 22:57:41 +00004553- Issue #3156: Fix inconsistent behavior of the bytearray type: all
4554 its methods now allow for items objects that can be converted to
4555 an integer using operator.index().
4556
Mark Dickinson64b7e502008-07-16 09:40:03 +00004557- Issue #3360: Fix incorrect parsing of '020000000000.0', which
4558 produced a ValueError instead of giving the correct float.
4559
Eric Smitha5fa5a22008-07-16 00:11:49 +00004560- Issue #3083: Add alternate (#) formatting for bin, oct, hex output
4561 for str.format(). This adds the prefix 0b, 0o, or 0x, respectively.
4562
Mark Dickinson7103aa42008-07-15 19:08:33 +00004563- Issue #3008: the float type has a new instance method 'float.hex'
4564 and a new class method 'float.fromhex' to convert floating-point
4565 numbers to and from hexadecimal strings, respectively.
4566
Nick Coghlan6d6bd442008-07-15 15:40:22 +00004567- Issue #2235: __hash__ is once again inherited by default. To allow
4568 collections.Hashable to remain meaningful in the presence of the
4569 default hash implementation (object.__hash__), it is now possible
4570 to explicit block inheritance of hash by setting __hash__=None at
4571 the Python level, or tp_hash=PyObject_HashNotImplemented at the C
4572 level.
4573
Nick Coghlanb028f502008-07-13 14:52:36 +00004574- Issue #3221: Issue a RuntimeWarning instead of raising SystemError if
4575 the parent module cannot be found while performing an absolute import.
4576 This means that an incorrectly defined __package__ attribute will
4577 now only prevent relative imports in that module rather than causing
4578 all imports from that module to fail.
4579
Nick Coghlan14ff9942008-07-08 14:21:42 +00004580- Issue #2517: Allow unicode messages in Exceptions again by correctly
4581 bypassing the instance dictionary when looking up __unicode__ on
4582 new-style classes.
4583
Amaury Forgeot d'Arcbdd941f2008-07-01 20:38:04 +00004584- Issue #3242: Fix a crash inside the print statement, if sys.stdout is
4585 set to a custom object whose write() method happens to install
4586 another file in sys.stdout.
4587
Amaury Forgeot d'Arc1f40c8a2008-06-30 22:42:40 +00004588- Issue #3088: Corrected a race condition in classes derived from
4589 threading.local: the first member set by a thread could be saved in
4590 another thread's dictionary.
4591
Mark Dickinson1ec2fcd2008-06-20 14:53:43 +00004592- Issue #3004: Minor change to slice.indices(): the start and stop
4593 arguments are now treated identically, making the behaviour easier
4594 to describe and understand. For example, slice(None, -10,
4595 1).indices(9) now returns (0, 0, 1) instead of (0, -1, 1), and
4596 slice(None, 10, -1).indices(10) returns (9, 9, -1) instead of (9,
4597 10, -1).
4598
Georg Brandl278fc502008-07-19 12:46:12 +00004599- Issue #3219: Calling a function with repeated keyword arguments,
4600 f(a=2, a=23), would not cause a syntax error. This was a regression
4601 from 2.4 caused by the switch to the new compiler.
Benjamin Peterson175e4d92008-07-01 19:34:52 +00004602
Georg Brandl278fc502008-07-19 12:46:12 +00004603- Issue #2862: Make int and float freelist management consistent with
4604 other freelists. Changes their CompactFreeList apis into
4605 ClearFreeList apis and calls them via gc.collect().

Thomas Heller57adf222008-08-14 19:10:48 +00004610- Issue #3554: ctypes.string_at and ctypes.wstring_at did call Python
4611 api functions without holding the GIL, which could lead to a fatal
4612 error when they failed.
4613
Martin v. Löwisaabf4042008-08-02 07:20:25 +00004614- Issue #799428: Fix Tkinter.Misc._nametowidget to unwrap Tcl command objects.

4623 ForkingPickler.register() to resolve conflict with ctypes.
4624
Vinay Sajip51e65192008-07-18 09:01:10 +00004625- Issue #3090: Fixed ARCHFLAGS parsing on OS/X
Jesse Noller13e9d582008-07-16 14:32:36 +00004626
Thomas Heller880f5292008-07-15 19:39:38 +00004627- Issue #3313: Fixed a crash when a failed dlopen() call does not set
4628 a valid dlerror() message.
4629
Thomas Heller2bad6572008-07-15 17:19:50 +00004630- Issue #3258: Fixed a crash when a ctypes POINTER type to an
4631 incomplete structure was created.

4636
Andrew M. Kuchlingcc3f2b12008-07-10 14:43:31 +00004637- Issue #3301: Bisect module behaved badly when lo was negative.
Raymond Hettinger3cd1e422008-07-10 14:03:19 +00004638
Amaury Forgeot d'Arc0f7cddc2008-07-06 21:34:39 +00004639- Issue #839496: SimpleHTTPServer used to open text files in text mode. This is
4640 both unnecessary (HTTP allows text content to be sent in several forms) and
Andrew M. Kuchlingcc3f2b12008-07-10 14:43:31 +00004641 wrong because the actual transmitted size could differ from the
Amaury Forgeot d'Arc0f7cddc2008-07-06 21:34:39 +00004642 content-length. The problem had been corrected in the 2.4 branch, but never
4643 merged into trunk.
4644
Georg Brandle78fbcc2008-07-05 10:13:36 +00004645- Issue #2663: add filtering capability to shutil.copytree().

Andrew M. Kuchlingcc3f2b12008-07-10 14:43:31 +00004656 when completed.
Facundo Batista66c52772008-07-02 16:52:55 +00004657
Nick Coghlanc060b0e2008-07-02 13:09:19 +00004658- Issue #3190: Pydoc now hides the automatic module attribute __package__ (the
4659 handling is now the same as that of other special attributes like __name__).
4660
Brett Cannon8bb8fa52008-07-02 01:57:08 +00004661- Issue #2885 (partial): The urllib.urlopen() function has been deprecated for
4662 removal in Python 3.0 in favor of urllib2.urlopen().

5115 using the 'warning's machinery in such places as the parser where
5116 use of pure Python code is not possible. Both the ``showarning()``
5117 and ``formatwarning()`` gain an optional 'line' argument which is
5118 not called by default for backwards-compatibility reasons. Setting
5119 ``warnings.showwarning()`` to an implementation that lacks support
5120 for the ``line`` argument will raise a DeprecationWarning.

Georg Brandl3ee81df2008-05-17 18:14:43 +00005183- Issue #2550: The approach used by client/server code for obtaining
5184 ports to listen on in network-oriented tests has been refined in an
5185 effort to facilitate running multiple instances of the entire
5186 regression test suite in parallel without issue.
5187 test_support.bind_port() has been fixed such that it will always
5188 return a unique port -- which wasn't always the case with the
5189 previous implementation, especially if socket options had been set
5190 that affected address reuse (i.e. SO_REUSEADDR, SO_REUSEPORT). The
5191 new implementation of bind_port() will actually raise an exception
5192 if it is passed an AF_INET/SOCK_STREAM socket with either the
5193 SO_REUSEADDR or SO_REUSEPORT socket option set. Furthermore, if
5194 available, bind_port() will set the SO_EXCLUSIVEADDRUSE option on
5195 the socket it's been passed. This currently only applies to
5196 Windows. This option prevents any other sockets from binding to the
5197 host/port we've bound to, thus removing the possibility of the
5198 'non-deterministic' behaviour, as Microsoft puts it, that occurs
5199 when a second SOCK_STREAM socket binds and accepts to a host/port
5200 that's already been bound by another socket. The optional preferred
5201 port parameter to bind_port() has been removed. Under no
5202 circumstances should tests be hard coding ports!
5203
5204 test_support.find_unused_port() has also been introduced, which will
5205 pass a temporary socket object to bind_port() in order to obtain an
5206 unused port. The temporary socket object is then closed and
5207 deleted, and the port is returned. This method should only be used
5208 for obtaining an unused port in order to pass to an external program
5209 (i.e. the -accept [port] argument to openssl's s_server mode) or as
5210 a parameter to a server-oriented class that doesn't give you direct
5211 access to the underlying socket used.
5212
5213 Finally, test_support.HOST has been introduced, which should be used
5214 for the host argument of any relevant socket calls (i.e. bind and
5215 connect).
Trent Nelsone41b0062008-04-08 23:47:30 +00005216
5217 The following tests were updated to following the new conventions:
Georg Brandl3ee81df2008-05-17 18:14:43 +00005218 test_socket, test_smtplib, test_asyncore, test_ssl, test_httplib,
Trent Nelsone41b0062008-04-08 23:47:30 +00005219 test_poplib, test_ftplib, test_telnetlib, test_socketserver,
5220 test_asynchat and test_socket_ssl.
5221
Georg Brandl3ee81df2008-05-17 18:14:43 +00005222 It is now possible for multiple instances of the regression test
5223 suite to run in parallel without issue.

Eric Smitha73fbe72008-02-23 03:09:44 +00005502- Added the future_builtins module, which contains hex() and oct().
5503 These are the PEP 3127 version of these functions, designed to be
5504 compatible with the hex() and oct() builtins from Python 3.0. They
5505 differ slightly in their output formats from the existing, unchanged
5506 Python 2.6 builtins. The expected usage of the future_builtins
5507 module is:
5508 from future_builtins import hex, oct
5509
Eric Smith7ef40bf2008-02-20 23:34:22 +00005510- Issue #1600: Modifed PyOS_ascii_formatd to use at most 2 digit
5511 exponents for exponents with absolute value < 100. Follows C99
5512 standard. This is a change on Windows, which would use 3 digits.
5513 Also, added 'n' to the formats that PyOS_ascii_formatd understands,
5514 so that any alterations it does to the resulting string will be
5515 available in stringlib/formatter.h (for float.__format__).
5516
Eric Smith5a3c1352008-02-19 13:21:56 +00005517- Implemented PEP 3101, Advanced String Formatting. This adds a new
5518 builtin format(); a format() method for str and unicode; a
5519 __format__() method to object, str, unicode, int, long, float, and
5520 datetime; the class string.Formatter; and the C API
5521 PyObject_Format().
5522
Georg Brandl3ee81df2008-05-17 18:14:43 +00005523- Fixed several potential crashes, all caused by specially crafted
5524 __del__ methods exploiting objects in temporarily inconsistent
5525 state.
Amaury Forgeot d'Arc632fad32008-02-16 20:55:24 +00005526
Vinay Sajipb7edfc42008-04-02 21:10:23 +00005527- Issue #2115: Important speedup in setting __slot__ attributes. Also
Georg Brandl3ee81df2008-05-17 18:14:43 +00005528 prevent a possible crash: an Abstract Base Class would try to access
5529 a slot on a registered virtual subclass.

Georg Brandl3ee81df2008-05-17 18:14:43 +00005534- Clear all free lists during a gc.collect() of the highest generation
5535 in order to allow pymalloc to free more arenas. Python may give back
5536 memory to the OS earlier.
Christian Heimes3b718a72008-02-14 12:47:33 +00005537
Georg Brandl3ee81df2008-05-17 18:14:43 +00005538- Issue #2045: Fix an infinite recursion triggered when printing a
5539 subclass of collections.defaultdict, if its default_factory is set
5540 to a bound method.
Amaury Forgeot d'Arcb01aa432008-02-08 00:56:02 +00005541
Christian Heimesf75dbef2008-02-08 00:11:31 +00005542- Fixed a minor memory leak in dictobject.c. The content of the free
5543 list was not freed on interpreter shutdown.
5544
Georg Brandl21e99f42010-03-07 15:23:59 +00005545- Limit free list of method and built-in function objects to 256

Christian Heimes6075a822008-02-06 12:44:34 +00005547
Georg Brandl3ee81df2008-05-17 18:14:43 +00005548- Patch #1953: Added ``sys._compact_freelists()`` and the C API
5549 functions ``PyInt_CompactFreeList`` and ``PyFloat_CompactFreeList``
Christian Heimes422051a2008-02-04 18:00:12 +00005550 to compact the internal free lists of pre-allocted ints and floats.
5551
Georg Brandl3ee81df2008-05-17 18:14:43 +00005552- Issue #1983: Fixed return type of fork(), fork1() and forkpty()
5553 calls. Python expected the return type int but the fork familie
5554 returns pi_t.
Christian Heimes951cc0f2008-01-31 23:08:23 +00005555

Georg Brandl3ee81df2008-05-17 18:14:43 +00005568- Patch #1473257: generator objects gain a gi_code attribute. This is
5569 the same object as the func_code attribute of the function that
5570 produced the generator.
Georg Brandl0cdf9a32008-01-26 14:14:20 +00005571
Georg Brandl3ee81df2008-05-17 18:14:43 +00005572- Issue #1920: "while 0" statements were completely removed by the
5573 compiler, even in the presence of an "else" clause, which is
5574 supposed to be run when the condition is false. Now the compiler
5575 correctly emits bytecode for the "else" suite.
Amaury Forgeot d'Arc31eaafe2008-01-24 22:59:25 +00005576
Guido van Rossumeead05f2008-01-24 18:21:02 +00005577- A few crashers fixed: weakref_in_del.py (issue #1377858);
5578 loosing_dict_ref.py (issue #1303614, test67.py);
5579 borrowed_ref_[34].py (not in tracker).

5584
Georg Brandl3ee81df2008-05-17 18:14:43 +00005585- Issue #1915: Python compiles with --enable-unicode=no again. However
Christian Heimes082c9b02008-01-23 14:20:50 +00005586 several extension methods and modules do not work without unicode
5587 support.
5588

5591
Georg Brandl14404b62008-01-19 19:27:05 +00005592- Issue #1679: "0x" was taken as a valid integer literal.
5593
Georg Brandl6caad7d2008-01-26 14:19:22 +00005594- Issue #1865: ``bytes`` as an alias for ``str`` and b"" as an alias "" were
Christian Heimes288e89a2008-01-18 18:24:07 +00005595 added.
5596
Christian Heimesc94e2b52008-01-14 04:13:37 +00005597- sys.float_info / PyFloat_GetInfo: The floating point information
5598 object was converted from a dict to a specialized structseq object.
5599
Georg Brandl3ee81df2008-05-17 18:14:43 +00005600- Patch #1816: Added sys.flags structseq. It exposes the status of
5601 most command line arguments and PYTHON* environment variables.
Christian Heimesf31b69f2008-01-14 03:42:48 +00005602
Georg Brandl3ee81df2008-05-17 18:14:43 +00005603- Objects/structseq.c: Implemented new structseq representation. The

Georg Brandl3ee81df2008-05-17 18:14:43 +00005607- Patch #1700288: added a type attribute cache that caches method
5608 accesses, resulting in speedups in heavily object-oriented code.
Amaury Forgeot d'Arce4c270c2008-01-14 00:29:41 +00005609
Neal Norwitz3fc15b82008-01-10 05:42:58 +00005610- Bug #1776: __import__() no longer accepts filenames on any platform.
5611 The first parameter to __import__() must be a valid module name.

Georg Brandlaed6c662008-01-07 17:25:53 +00005613- Patch #1668: renamed THREADDEBUG envvar to PYTHONTHREADDEBUG.
5614
Georg Brandl3ee81df2008-05-17 18:14:43 +00005615- Patch #602345: Add -B command line option, PYTHONDONTWRITEBYTECODE
5616 envvar and sys.dont_write_bytecode attribute. All these can be set
5617 to forbid Python to attempt to write compiled bytecode files.
Georg Brandl2da0fce2008-01-07 17:09:35 +00005618
Georg Brandl3ee81df2008-05-17 18:14:43 +00005619- Improve some exception messages when Windows fails to load an
5620 extension module. Now we get for example '%1 is not a valid Win32
5621 application' instead of 'error code 193'.

Christian Heimes0a8143f2007-12-18 23:22:54 +00005628- Issue #1635: Platform independent creation and representation of NaN
Georg Brandl3ee81df2008-05-17 18:14:43 +00005629 and INF. float("nan"), float("inf") and float("-inf") now work on
5630 every platform with IEEE 754 semantics.

Georg Brandl3ee81df2008-05-17 18:14:43 +00005632- Compiler now generates simpler and faster code for dictionary
5633 literals. The oparg for BUILD_MAP now indicates an estimated
5634 dictionary size. There is a new opcode, STORE_MAP, for adding
5635 entries to the dictionary.

5647
Nick Coghlanef01d822007-12-03 12:55:17 +00005648- PEP 366: Allow explicit relative imports when executing modules

Georg Brandl3ee81df2008-05-17 18:14:43 +00005664- Patch #1739468: Directories and zipfiles containing a __main__.py
5665 file can now be directly executed by passing their name to the
5666 interpreter. The directory/zipfile is automatically inserted as the
5667 first entry in sys.path.
Nick Coghlan327a39b2007-11-18 11:56:28 +00005668
Georg Brandl3ee81df2008-05-17 18:14:43 +00005669- Issue #1265: Fix a problem with sys.settrace, if the tracing
5670 function uses a generator expression when at the same time the
5671 executed code is closing a paused generator.
Amaury Forgeot d'Arc0d75f092007-11-13 21:54:28 +00005672
Raymond Hettinger1760c8a2007-11-08 02:52:43 +00005673- sets and frozensets now have an isdisjoint() method.
5674

5678
Georg Brandl21e99f42010-03-07 15:23:59 +00005679- The enumerate() built-in function is no longer bounded to sequences
Georg Brandl3ee81df2008-05-17 18:14:43 +00005680 smaller than LONG_MAX. Formerly, it raised an OverflowError. Now,
5681 automatically shifts from ints to longs.
Raymond Hettinger8f669372007-10-03 21:18:11 +00005682
Georg Brandl3ee81df2008-05-17 18:14:43 +00005683- Issue #1686386: Tuple's tp_repr did not take into account the
5684 possibility of having a self-referential tuple, which is possible
5685 from C code. Nor did object's tp_str consider that a type's tp_str
5686 could do something that could lead to an inifinite recursion.
5687 Py_ReprEnter() and Py_EnterRecursiveCall(), respectively, fixed the
5688 issues.
Brett Cannon0b14f242007-09-30 19:45:10 +00005689
Georg Brandl3ee81df2008-05-17 18:14:43 +00005690- Issue #1164: It was possible to trigger deadlock when using the
5691 'print' statement to write to a file since the GIL was not released
5692 as needed. Now PyObject_Print() does the right thing along with
5693 various tp_print implementations of the built-in types and those in
5694 the collections module.
Brett Cannon01531592007-09-17 03:28:34 +00005695
Georg Brandl3ee81df2008-05-17 18:14:43 +00005696- Issue #1147: Exceptions were directly allowing string exceptions in
5697 their throw() method even though string exceptions no longer
5698 allowed.
Brett Cannon4c20bc42007-09-11 21:02:28 +00005699
Georg Brandl3ee81df2008-05-17 18:14:43 +00005700- Issue #1096: Prevent a segfault from getting the repr of a very
5701 deeply nested list by using the recursion counter.
Brett Cannona0c05512007-09-10 21:38:27 +00005702
Brett Cannon1e534b52007-09-07 04:18:30 +00005703- Issue #1202533: Fix infinite recursion calls triggered by calls to
Georg Brandl3ee81df2008-05-17 18:14:43 +00005704 PyObject_Call() never calling back out to Python code to trigger
5705 recursion depth updates/checks. Required the creation of a static
5706 RuntimeError instance in case normalizing an exception put the
5707 recursion check value past its limit. Fixes crashers
5708 infinite_rec_(1|2|4|5).py.
Brett Cannon1e534b52007-09-07 04:18:30 +00005709
Georg Brandl3ee81df2008-05-17 18:14:43 +00005710- Patch #1031213: Decode source line in SyntaxErrors back to its

Neal Norwitz0ac60192007-05-27 04:08:54 +00005723- Add new attribute names for function objects. All the func_* become
Georg Brandl3ee81df2008-05-17 18:14:43 +00005724 __*__ attributes. (Some already existed, e.g., __doc__ and
5725 __name__.)
Neal Norwitz0ac60192007-05-27 04:08:54 +00005726
Neal Norwitz8b2bfbc2007-05-23 06:35:32 +00005727- Add -3 option to the interpreter to warn about features that are
5728 deprecated and will be changed/removed in Python 3.0.
5729
Georg Brandl2134e752007-05-21 20:34:16 +00005730- Patch #1686487: you can now pass any mapping after '**' in function
5731 calls.
5732
Collin Winter62903052007-05-18 23:11:24 +00005733- except clauses may now be spelled either "except E, target:" or
Georg Brandl3ee81df2008-05-17 18:14:43 +00005734 "except E as target:". This is to provide forwards compatibility
5735 with Python 3.0.
Collin Winter62903052007-05-18 23:11:24 +00005736
Brett Cannon229cee22007-05-05 01:34:02 +00005737- Deprecate BaseException.message as per PEP 352.
5738
Georg Brandl3ee81df2008-05-17 18:14:43 +00005739- Issue #1303614: don't expose object's __dict__ when the dict is
Georg Brandl21e99f42010-03-07 15:23:59 +00005740 inherited from a built-in base.
Armin Rigo9790a272007-05-02 19:23:31 +00005741
Vinay Sajip8549ce32007-05-06 17:53:37 +00005742- When __slots__ are set to a unicode string, make it work the same as
Neal Norwitzcbd9ee62007-04-14 05:25:50 +00005743 setting a plain string, ie don't expand to single letter identifiers.
5744
Raymond Hettinger13936692007-04-11 18:40:58 +00005745- Request #1191699: Slices can now be pickled.
5746
Raymond Hettinger4db5fe92007-04-12 04:10:00 +00005747- Request #1193128: str.translate() now allows a None argument for
5748 translations that only remove characters without re-mapping the
5749 remaining characters.
5750
Georg Brandl5cb76c12007-03-21 09:00:39 +00005751- Patch #1682205: a TypeError while unpacking an iterable is no longer
5752 masked by a generic one with the message "unpack non-sequence".
5753
Neal Norwitzaa754b72007-03-21 06:39:48 +00005754- Remove unused file Python/fmod.c.
5755
Guido van Rossum143b5642007-03-23 04:58:42 +00005756- Bug #1683368: The object.__init__() and object.__new__() methods are
5757 now stricter in rejecting excess arguments. The only time when
5758 either allows excess arguments is when it is not overridden and the
5759 other one is. For backwards compatibility, when both are
5760 overridden, it is a deprecation warning (for now; maybe a Py3k
Guido van Rossum234b1ff2007-03-23 19:39:01 +00005761 warning later). Also, type.__init__() insists on the same signature
5762 as supported by type.__new__().
Guido van Rossum143b5642007-03-23 04:58:42 +00005763
Georg Brandl3ee81df2008-05-17 18:14:43 +00005764- Patch #1675423: PyComplex_AsCComplex() now tries to convert an
5765 object to complex using its __complex__() method before falling back
5766 to the __float__() method. Therefore, the functions in the cmath
5767 module now can operate on objects that define a __complex__()
5768 method.
Georg Brandl2b869942007-03-17 16:08:45 +00005769
Georg Brandl3ee81df2008-05-17 18:14:43 +00005770- Patch #1623563: allow __class__ assignment for classes with
5771 __slots__. The old and the new class are still required to have the
5772 same slot names.
Žiga Seilnacht6f2d09c2007-03-16 11:59:38 +00005773
Georg Brandl3ee81df2008-05-17 18:14:43 +00005774- Patch #1642547: Fix an error/crash when encountering syntax errors

5778 ``object.__reduce_ex__()`` is called with an object that is faking
5779 its type.
Žiga Seilnacht20f43d32007-03-15 11:44:55 +00005780
Georg Brandl3ee81df2008-05-17 18:14:43 +00005781- Patch #1680015: Don't modify __slots__ tuple if it contains an

5785
Georg Brandl7b9c5552007-03-12 14:30:05 +00005786- Bug #1678647: write a newline after printing an exception in any
5787 case, even when converting the value to a string failed.
5788
Georg Brandl871f1bc2007-03-12 13:17:36 +00005789- The dir() function has been extended to call the __dir__() method on
Georg Brandl3ee81df2008-05-17 18:14:43 +00005790 its argument, if it exists. If not, it will work like before. This
5791 allows customizing the output of dir() in the presence of a
5792 __getattr__().
Georg Brandl871f1bc2007-03-12 13:17:36 +00005793
Collin Winter276887b2007-03-12 16:11:39 +00005794- Patch #922167: Python no longer segfaults when faced with infinitely
5795 self-recursive reload() calls (as reported by bug #742342).
5796
Georg Brandl3ee81df2008-05-17 18:14:43 +00005797- Patch #1675981: remove unreachable code from ``type.__new__()``

Georg Brandl3ee81df2008-05-17 18:14:43 +00005800- Patch #1491866: change the complex() constructor to allow
5801 parthensized forms. This means complex(repr(x)) now works instead of
5802 raising a ValueError.
Collin Wintere38051d2007-03-09 20:33:07 +00005803
Georg Brandlaa2321b2007-03-07 00:40:28 +00005804- Patch #703779: unset __file__ in __main__ after running a file. This
Georg Brandl3ee81df2008-05-17 18:14:43 +00005805 makes the filenames the warning module prints much more sensible
5806 when a PYTHONSTARTUP file is used.
Georg Brandlaa2321b2007-03-07 00:40:28 +00005807
Georg Brandl49aafc92007-03-07 00:34:46 +00005808- Variant of patch #697613: don't exit the interpreter on a SystemExit
5809 exception if the -i command line option or PYTHONINSPECT environment
Georg Brandl3ee81df2008-05-17 18:14:43 +00005810 variable is given, but break into the interactive interpreter just
5811 like on other exceptions or normal program exit.

Georg Brandl0fca97a2007-03-05 22:28:08 +00005819- Patch #1674228: when assigning a slice (old-style), check for the
5820 sq_ass_slice instead of the sq_slice slot.
5821
Georg Brandl3ee81df2008-05-17 18:14:43 +00005822- When printing an unraisable error, don't print exceptions. before
5823 the name. This duplicates the behavior whening normally printing
5824 exceptions.

Georg Brandl3ee81df2008-05-17 18:14:43 +00006357 AttributeError instead of an IOError when the server's response
6358 didn't contain a valid HTTP status line.
Georg Brandlf66b6032007-03-14 08:27:52 +00006359

Georg Brandl3ee81df2008-05-17 18:14:43 +00006364- Patch #1429539: pdb now correctly initializes the __main__ module
6365 for the debugged script, which means that imports from __main__ work
Georg Brandlb6ae6aa2007-03-13 21:58:44 +00006366 correctly now.
6367

6374
Georg Brandl3ee81df2008-05-17 18:14:43 +00006375- Patch #1530482: add pydoc.render_doc() which returns the

6390
Georg Brandl92a6bae2007-03-13 17:43:32 +00006391- Patch #1603688: ConfigParser.SafeConfigParser now checks values that
Georg Brandl3ee81df2008-05-17 18:14:43 +00006392 are set for invalid interpolation sequences that would lead to
6393 errors on reading back those values.

6434

6436 returned string up to the first NUL character.

6447
Georg Brandl3ee81df2008-05-17 18:14:43 +00006448- unittest now verifies more of its assumptions. In particular,
6449 TestCase and TestSuite subclasses (not instances) are no longer
6450 accepted in TestSuite.addTest(). This should cause no
6451 incompatibility since it never made sense with ordinary subclasses
6452 -- the failure just occurred later, with a more cumbersome
6453 exception.
Georg Brandl9caadf82007-03-08 18:37:31 +00006454

Georg Brandl3ee81df2008-05-17 18:14:43 +00006823- Marshal.dumps() now expects exact type matches for int, long, float,
6824 complex, tuple, list, dict, set, and frozenset. Formerly, it would
6825 silently miscode subclasses of those types. Now, it raises a

Gregory P. Smithec10a4a2007-11-05 02:32:26 +00006841- pybsddb.sf.net Bug #477182: Load the database flags at database open
Georg Brandl3ee81df2008-05-17 18:14:43 +00006842 time so that opening a database previously created with the DB_DUP
6843 or DB_DUPSORT flag set will keep the proper behavior on subsequent
6844 opens. Specifically: dictionary assignment to a DB object will
6845 replace all values for a given key when the database allows
6846 duplicate values. DB users should use DB.put(k, v) when they want
6847 to store duplicates; not DB[k] = v.

6854 characters with ASCII value less than 32. Also, it correctly quotes
6855 dots only if they occur on a single line, as opposed to the previous
6856 behavior of quoting dots if they are the second character of any
6857 line.

7203 of w# format code incorrectly truncated the length to an int, even
7204 when PY_SSIZE_T_CLEAN is set. The str.decode method used to return
7205 incorrect results with huge strings.

Georg Brandl3ee81df2008-05-17 18:14:43 +00007235- Added case insensitive comparison methods ``PyOS_stricmp(char*,
7236 char*)`` and ``PyOS_strnicmp(char*, char*, Py_ssize_t)``.
