1283 In particular, fix extension module build failures when trying to use
1284 32-bit-only installer Pythons on systems with Xcode 4 (currently
1285 OS X 10.8, 10.7, and optionally 10.6).
1286 * Backport 3.3.0 fixes to 2.7 branch (for release in 2.7.4)
1287 * Since Xcode 4 removes ppc support, extension module builds now
1288 check for ppc compiler support and by default remove ppc and
1289 ppc64 archs when they are not available.
1290 * Extension module builds now revert to using system installed
1291 headers and libs (/usr and /System/Library) if the SDK used
1292 to build the interpreter is not installed or has moved.
1293 * Try to avoid building extension modules with deprecated
1294 and problematic Apple llvm-gcc compiler. If original compiler
1295 is not available, use clang instead by default.

1727 Distutils-based packages with C extension modules may fail because
1728 Apple has removed gcc-4.2, the version used to build python.org
1729 64-bit/32-bit Pythons. If the user does not explicitly override
1730 the default C compiler by setting the CC environment variable,
1731 Distutils will now attempt to compile extension modules with clang
1732 if gcc-4.2 is required but not found. Also as a convenience, if
1733 the user does explicitly set CC, substitute its value as the default
1734 compiler in the Distutils LDSHARED configuration variable for OS X.
1735 (Note, the python.org 32-bit-only Pythons use gcc-4.0 and the 10.4u
1736 SDK, neither of which are available in Xcode 4. This change does not
1737 attempt to override settings to support their use with Xcode 4.)

Ned Deily87e82bb2011-06-28 19:52:59 -07001987- Issue #9516: On Mac OS X, change Distutils to no longer globally attempt to
1988 check or set the MACOSX_DEPLOYMENT_TARGET environment variable for the
1989 interpreter process. This could cause failures in non-Distutils subprocesses
1990 and was unreliable since tests or user programs could modify the interpreter
Ezio Melotti302ad8d2013-01-19 19:44:58 +02001991 environment after Distutils set it. Instead, have Distutils set the
Ned Deily87e82bb2011-06-28 19:52:59 -07001992 deployment target only in the environment of each build subprocess. It is
1993 still possible to globally override the default by setting
1994 MACOSX_DEPLOYMENT_TARGET before launching the interpreter; its value must be
1995 greater or equal to the default value, the value with which the interpreter
1996 was built.

2026 the ticker doesn't have to wind down to zero from the old starting point
2027 before the new interval takes effect. And if the user increases the
2028 interval, it makes sure the new limit takes effect right away rather have an
2029 early task switch before recognizing the new interval.

Raymond Hettinger20397532010-09-12 02:11:45 +00003009- Issue #9825: removed __del__ from the definition of collections.OrderedDict.
3010 This prevents user-created self-referencing ordered dictionaries from
3011 becoming permanently uncollectable GC garbage. The downside is that
3012 removing __del__ means that the internal doubly-linked list has to wait for
3013 GC collection rather than freeing memory immediately when the refcnt drops
3014 to zero.
3015

3022 to fetch the original errno, or to filter timeout errors. Now the
3023 original error is re-raised.

3044
R. David Murray7c4bf552010-08-25 01:45:57 +00003045- Issue #1194222: email.utils.parsedate now returns RFC2822 compliant four
3046 character years even if the message contains RFC822 two character years.
3047
Daniel Stutzbach91287322010-08-24 21:09:30 +00003048- Issue #8750: Fixed MutableSet's methods to correctly handle

3063 ignored by the buffered IO layer anymore.
3064
Benjamin Peterson52c36052010-08-21 03:03:22 +00003065- Issue #2521: Use weakrefs on for caching in the abc module, so that classes

3067
Raymond Hettingera54b2da2010-08-17 19:03:06 +00003068- Issue #9626: the view methods for collections.OrderedDict() were returning

Antoine Pitroucb4f47c2010-08-11 13:40:17 +00003080- Issue #9550: a BufferedReader could issue an additional read when the
3081 original read request had been satisfied, which could block indefinitely
3082 when the underlying raw IO channel was e.g. a socket. Report and original
3083 patch by Jason V. Miller.
3084
Fred Drake0a1fa0e2010-08-10 13:09:54 +00003085- Issue #9551: Don't raise TypeError when setting the value to None for

3739 indefinitely if the other end didn't respond.
3740
Georg Brandlfee0f442010-05-22 21:26:21 +00003741- The do_handshake() method of SSL objects now adjusts the blocking mode of the

Georg Brandlfee0f442010-05-22 21:26:21 +00003752- Issue #8451: Syslog module now uses basename(sys.argv[0]) instead of the
3753 string "python" as the *ident*. openlog() arguments are all optional and
3754 keywords.

Mark Dickinsond2f3e3f2010-05-05 22:23:58 +00003834 (Optimization was unintentionally turned on in gcc --with-pydebug builds in

3858
Philip Jenveyaebbaeb2010-04-06 23:24:45 +00003859- Issue #7301: Add environment variable $PYTHONWARNINGS.
3860
Benjamin Peterson3a1dfa22010-04-06 21:50:00 +00003861- Issue #8329: Don't return the same lists from select.select when no fds are
3862 changed.
3863
Georg Brandlfee0f442010-05-22 21:26:21 +00003864- Issue #8259: ``1L << (2**31)`` no longer produces an 'outrageous shift error'
Mark Dickinson82791672010-04-06 16:47:55 +00003865 on 64-bit machines. The shift count for either left or right shift is
3866 permitted to be up to sys.maxsize.
3867
Benjamin Peterson4ceeeb02010-04-03 22:48:51 +00003868- Ensure that tokenization of identifiers is not affected by locale.

3873
Georg Brandlfee0f442010-05-22 21:26:21 +00003874- Issue #7994: Issue a PendingDeprecationWarning if object.__format__ is called
3875 with a non-empty format string. This is an effort to future-proof user
3876 code. If a derived class does not currently implement __format__ but later
3877 adds its own __format__, it would most likely break user code that had
Antoine Pitrou01a196a2011-01-02 20:05:11 +00003878 supplied a format string. This will be changed to a DeprecationWarning in
Georg Brandlfee0f442010-05-22 21:26:21 +00003879 Python 3.3 and it will be an error in Python 3.4.

Georg Brandlfee0f442010-05-22 21:26:21 +00003912- Issue #8257: The Decimal construct now accepts a float instance directly,
3913 converting that float to a Decimal of equal value:
Mark Dickinson8a950712010-04-03 15:47:46 +00003914

3917
Raymond Hettinger34c35b22010-04-03 10:22:00 +00003918- collections.Counter() now supports a subtract() method.
3919
Georg Brandlfee0f442010-05-22 21:26:21 +00003920- The functools module now has a total_ordering() class decorator to simplify
3921 the specification of rich comparisons.

Georg Brandlfee0f442010-05-22 21:26:21 +00003929- Issue #7279: Comparisons involving a Decimal signaling NaN now signal
3930 InvalidOperation instead of returning False. (Comparisons involving a quiet
3931 NaN are unchanged.) Also, Decimal quiet NaNs are now hashable; Decimal
3932 signaling NaNs remain unhashable.
Mark Dickinsone096e822010-04-02 10:17:07 +00003933
Georg Brandlfee0f442010-05-22 21:26:21 +00003934- Issue #2531: Comparison operations between floats and Decimal instances now
3935 return a result based on the numeric values of the operands; previously they
3936 returned an arbitrary result based on the relative ordering of id(float) and
3937 id(Decimal).

Barry Warsawf7f2d6f2010-03-31 21:07:16 +00003939- Issue #8233: When run as a script, py_compile.py optionally takes a single
Georg Brandlfee0f442010-05-22 21:26:21 +00003940 argument `-` which tells it to read files to compile from stdin. Each line is
3941 read on demand and the named file is compiled immediately. (Original patch by

Georg Brandlfee0f442010-05-22 21:26:21 +00003951- Comparisons using one of <, <=, >, >= between a complex instance and a
3952 Fractions instance now raise TypeError instead of returning True/False. This
3953 makes Fraction <=> complex comparisons consistent with int <=> complex, float
3954 <=> complex, and complex <=> complex comparisons.

Georg Brandlba83f822010-03-14 09:50:54 +00004372 file position when calling `truncate()`. It would previously change the file
4373 position to the given argument, which goes against the tradition of
Antoine Pitrouf3fa0742010-01-31 22:26:04 +00004374 ftruncate() and other truncation APIs. Patch by Pascal Chambon.

4377 class used to represent files stored inside an archive. The new
4378 implementation is significantly faster and can be wrapped in a

4380 where interleaved calls to ``read()`` and ``readline()`` give wrong results.

Benjamin Peterson4f51baf2009-12-05 18:40:02 +00004463What's New in Python 2.7 alpha 2?

Georg Brandlba83f822010-03-14 09:50:54 +00004471- The ``__complex__()`` method is now looked up on the class of instances to
4472 make it consistent with other special methods.
Benjamin Petersonecdae192010-01-04 00:43:01 +00004473
Antoine Pitrou5b7139a2010-01-02 21:12:58 +00004474- Issue #7462: Implement the stringlib fast search algorithm for the `rfind`,
4475 `rindex`, `rsplit` and `rpartition` methods. Patch by Florent Xicluna.
4476
Mark Dickinson1b34d252010-01-01 17:27:30 +00004477- Issue #5080: A number of functions and methods previously produced a
Georg Brandlba83f822010-03-14 09:50:54 +00004478 DeprecationWarning when passed a float argument where an integer was expected.
4479 These functions and methods now raise TypeError instead. The majority of the
4480 effects of this change are in the extension modules, but some core functions
4481 and methods are affected: notably the 'chr', 'range' and 'xrange' builtins,
4482 and many unicode/str methods.

4493 used to drop the time part of the result.
4494
Georg Brandlba83f822010-03-14 09:50:54 +00004495- Issue #1811: Improve accuracy and cross-platform consistency for true division
4496 of integers: the result of a/b is now correctly rounded for ints a and b (at
4497 least on IEEE 754 platforms), and in particular does not depend on the
4498 internal representation of a long.
Mark Dickinson46572832009-12-27 14:55:57 +00004499
Georg Brandlba83f822010-03-14 09:50:54 +00004500- Issue #6108: ``unicode(exception)`` and ``str(exception)`` should return the
4501 same message when only ``__str__()`` (and not ``__unicode__()``) is overridden
4502 in the subclass.

Ronald Oussoren92919a62009-12-24 13:30:58 +00004505 executables on OSX.
4506
Georg Brandlba83f822010-03-14 09:50:54 +00004507 These executables now work properly with the arch(1) command: ``arch -ppc
4508 python`` will start a universal binary version of python in PPC mode (unlike
4509 previous releases).
Ronald Oussoren92919a62009-12-24 13:30:58 +00004510
Georg Brandlba83f822010-03-14 09:50:54 +00004511- Issue #1680159: Unicode coercion during an 'in' operation no longer masks the

Georg Brandlba83f822010-03-14 09:50:54 +00004532 renaming of `cPickle` to `pickle`. The warning was annoying since there's no

4570 the same as passing no argument.
4571
Georg Brandlba83f822010-03-14 09:50:54 +00004572- Issue #7348: ``StringIO.StringIO.readline(-1)`` now acts as if it got no

Georg Brandlba83f822010-03-14 09:50:54 +00004665- Issue #7117: ``repr(x)`` for a float x returns a result based on the shortest
4666 decimal string that's guaranteed to round back to x under correct rounding
4667 (with round-half-to-even rounding mode). Previously it gave a string based on
4668 rounding x to 17 decimal digits. repr(x) for a complex number behaves
4669 similarly. On platforms where the correctly-rounded strtod and dtoa code is
4670 not supported (see below), repr is unchanged.

Georg Brandlba83f822010-03-14 09:50:54 +00004672- Issue #7117: On almost all platforms: float-to-string and string-to-float
4673 conversions within Python are now correctly rounded. Places these conversions
4674 occur include: str for floats and complex numbers; the float and complex
4675 constructors; old-style and new-style numeric formatting; serialization and
4676 deserialization of floats and complex numbers using marshal, pickle and json;
4677 parsing of float and imaginary literals in Python code; Decimal-to-float
4678 conversion.
Mark Dickinsonb678de82009-11-19 18:41:49 +00004679
Georg Brandlba83f822010-03-14 09:50:54 +00004680 The conversions use a Python-adapted version of David Gay's well-known dtoa.c,
4681 providing correctly-rounded strtod and dtoa C functions. This code is
4682 supported on Windows, and on Unix-like platforms using gcc, icc or suncc as
4683 the C compiler. There may be a small number of platforms on which correct
4684 operation of this code cannot be guaranteed, so the code is not used: notably,
4685 this applies to platforms where the C double format is not IEEE 754 binary64,
4686 and to platforms on x86 hardware where the x87 FPU is set to 64-bit precision
4687 and Python's configure script is unable to determine how to change the FPU

Georg Brandlba83f822010-03-14 09:50:54 +00004691- Issue #7117: Backport round implementation from Python 3.x. ``round()`` now
4692 uses the correctly-rounded string <-> float conversions described above (when
4693 available), and so produces correctly rounded results that will display nicely
4694 under the float repr. There are two related small changes: (1) round now
4695 accepts any class with an ``__index__()`` method for its second argument (but
4696 no longer accepts floats for the second argument), and (2) an excessively
4697 large second integer argument (e.g., ``round(1.234, 10**100)``) no longer
4698 raises an exception.

Antoine Pitrouf8387af2009-03-23 18:41:45 +00004915- Issue #4688: Add a heuristic so that tuples and dicts containing only
Georg Brandlba83f822010-03-14 09:50:54 +00004916 untrackable objects are not tracked by the garbage collector. This can reduce
4917 the size of collections and therefore the garbage collection overhead on
4918 long-running programs, depending on their particular use of datatypes.

5077 this code path is really executed because I cannot move to such directory on

5104 PyUnicode_DecodeUTF8() once, remember the result and output it in a second

Georg Brandlba83f822010-03-14 09:50:54 +00006278 - Packing a float now always gives a Deprecation Warning. Previously it
6279 only warned for 'I', 'L', '*B', '*H', '*I', '*L'.

Georg Brandlba83f822010-03-14 09:50:54 +00006281 - If x is not an int, long or float, then packing x will always result in
6282 struct.error. Previously an x with an __int__ method could be packed by
6283 'b', 'B', 'h', 'H', 'i', 'l', '*b', '*h' ,'*i', '*l', and an x with a
6284 __long__ method could be packed by 'q', 'Q', '*q', '*Q'; for x with
6285 neither __int__ nor __long__, TypeError used to be raised (with a
6286 confusing error message) for 'I', 'L', '*B', '*H', '*I', '*L', and
6287 struct.error in other cases.

6290 argument with an __int__ method can be packed, but use of this feature
6291 triggers a DeprecationWarning.

Amaury Forgeot d'Arc05e34492008-09-10 22:04:45 +00006484- Issue #3743: In a few places, PY_FORMAT_SIZE_T was incorrectly used with

6486 PY_FORMAT_SIZE_T is designed to select the correct format for the OS
6487 ``printf`` function, whereas PyString_FromFormat has an independent

Brett Cannon672237d2008-09-09 00:49:16 +00006559 return a list or None rather than a custom object.
6560

Brett Cannon1eaf0742008-09-02 01:25:16 +00006585 warnings.catch_warnings() along with some API cleanup. Expanding the tests
6586 for catch_warnings() also led to an improvement in the raising of a
6587 DeprecationWarning related to warnings.warn_explicit().
6588
Benjamin Peterson973e6c22008-09-01 23:12:58 +00006589- The deprecation warnings for the old camelCase threading API were removed.

6611
Amaury Forgeot d'Arc293924b2008-09-02 23:19:56 +00006612- Issue #2975: When compiling several extension modules with Visual Studio 2008
6613 from the same python interpreter, some environment variables would grow
6614 without limit.
6615
Benjamin Peterson37346b22008-08-23 20:27:43 +00006616- Issue #3643: Added a few more checks to _testcapi to prevent segfaults by

Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00006653What's New in Python 2.6 beta 3?
6654================================
6655
Barry Warsaw07a4a382008-08-21 01:15:08 +00006656*Release date: 20-Aug-2008*
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00006657
6658Core and Builtins
6659-----------------
6660
Guido van Rossumf8402962008-08-20 15:01:50 +00006661- Issue #1878: Remove Py_TPFLAGS_HAVE_VERSION_TAG from
6662 Py_TPFLAGS_DEFAULT when not building the core. This means 3rd party
6663 extensions do not automatically benefit from the class attribute
6664 cache; they will have to explicitly add Py_TPFLAGS_HAVE_VERSION_TAG
6665 to their tp_flags field if they care. This is a backwards
6666 compatibility feature; in 3.0, all types will use the cache by
6667 default.
6668
Benjamin Petersonf647dc12008-08-20 01:27:30 +00006669- Keyword arguments can now follow starred arguments. (``f(a, *args,
6670 keyword=23)`` is now valid syntax.)
6671
Thomas Heller0ad5ae02008-08-19 19:25:04 +00006672- ctypes function pointers that are COM methods have a boolean True
6673 value again.
6674
Martin v. Löwisf91d46a2008-08-12 14:49:50 +00006675- Issue #3139: Make buffer-interface thread-safe wrt. PyArg_ParseTuple,
6676 by denying s# to parse objects that have a releasebuffer procedure,
6677 and introducing s*.
6678
Georg Brandl1e13ea92008-08-11 09:07:59 +00006679- Issue #3537: Fix an assertion failure when an empty but presized dict
6680 object was stored in the freelist.
6681
Mark Dickinsonb6467572008-08-04 21:30:09 +00006682- Issue #1481296: Make long(float('nan')) and int(float('nan')) raise
6683 ValueError consistently across platforms.
6684
Amaury Forgeot d'Arc39fd6722008-07-31 21:28:03 +00006685- Issue #3479: On platforms where sizeof(int) is smaller than sizeof(long)
6686 (64bit Unix, for example), unichr() would truncate its argument and return
6687 u'\x00' for unichr(2**32). Now it properly raises an OverflowError.
6688
Neal Norwitze7d8be82008-07-31 17:17:14 +00006689- Apply security patches from Apple.
6690
Amaury Forgeot d'Arc246daed2008-07-31 00:42:16 +00006691- Issue #2542: Now that issubclass() may call arbitrary code, ensure that
6692 PyErr_ExceptionMatches returns 0 when an exception occurs there.
6693
Antoine Pitrou92f82162008-07-25 22:22:08 +00006694- Issue #1819: function calls with several named parameters are now on
6695 average 35% faster (as measured by pybench).
6696
Amaury Forgeot d'Arce4921fe2008-07-21 22:00:38 +00006697- Issue #2378: An unexpected UnboundLocalError or NameError could appear when
6698 the python debugger steps into a class statement: the free variables (local
6699 variables defined in an outer scope) would be deleted from the outer scope.
6700
Gregory P. Smith0470bab2008-07-22 04:46:32 +00006701- Issue #2620: Overflow checking when allocating or reallocating memory
6702 was not always being done properly in some python types and extension
6703 modules. PyMem_MALLOC, PyMem_REALLOC, PyMem_NEW and PyMem_RESIZE have
6704 all been updated to perform better checks and places in the code that
6705 would previously leak memory on the error path when such an allocation
6706 failed have been fixed.
6707

6709-------
6710
Hirokazu Yamamoto838c79f2008-08-20 13:14:07 +00006711- Issue #3612: Added some missing basic types in ctypes.wintypes.
6712
Benjamin Petersone977ad42008-08-20 01:42:01 +00006713- The methods ``is_in_tuple()``, ``is_vararg()``, and ``is_keywordarg()`` of
6714 symtable.Symbol have been deprecated for removal in 3.0 and the next release.
6715
Amaury Forgeot d'Arc351ffb82008-08-18 19:23:47 +00006716- Issue #2234: distutils failed for some versions of the cygwin compiler. The
6717 version reported by these tools does not necessarily follow the python
6718 version numbering scheme, so the module is less strict when parsing it.
6719
Nick Coghlanf70385a2008-08-18 12:42:46 +00006720- Issue #2235: Added Py3k warnings for types which will become unhashable
6721 under the stricter __hash__ inheritance rules in 3.0. Several types
6722 which did not meet the rules for hash invariants and were already
6723 unhashable in 3.0 have now been explicitly flagged as unhashable in
6724 2.6 as well (collections.Mapping, collections.Set, unittest.TestSuite,
6725 xml.dom.minidom.NamedNodeMap, numbers.Number, UserList.UserList)
6726
Brett Cannon88f801d2008-08-18 00:46:22 +00006727- Update __all__ for cookielib, csv, os, urllib2, and weakref to include things

6729
Brett Cannon7b96f072008-08-18 00:41:11 +00006730- Remove an unneeded import of abc.ABCMeta from 'inspect'.
6731
Brett Cannon46225e72008-08-18 00:36:52 +00006732- Remove unneeded imports of 'sys' and 'warnings' from 'io'.

Brett Cannon25c9d6a2008-08-17 22:10:11 +00006734- Remove unneeded imports of 'warnings' from shelve, filecmp, and dummy_thread.
6735
Hirokazu Yamamoto41a81eb2008-08-17 13:10:46 +00006736- Issue #3575: Incremental decoder's decode function now takes bytearray
6737 by using 's*' instead of 't#'.
6738
Mark Dickinson3e4caeb2009-02-21 20:27:01 +00006739- Issue #2222: Fixed reference leak when occurred os.rename()
Hirokazu Yamamoto7f30a682008-08-17 09:46:56 +00006740 fails unicode conversion on 2nd parameter. (windows only)
6741
Georg Brandl222e2082010-08-01 22:27:39 +00006742- Issue #2464: urllib2 now supports a malformation in the URL received
Facundo Batista94f243a2008-08-17 03:38:39 +00006743 in a redirect.
6744
Brett Cannonabe423e2008-08-16 21:47:07 +00006745- Silence the DeprecationWarning raised when importing mimetools in
Brett Cannon721b1452008-08-16 22:00:27 +00006746 BaseHTTPServer, cgi (and rfc822), httplib.
Brett Cannonabe423e2008-08-16 21:47:07 +00006747
Facundo Batistaeb90b782008-08-16 14:44:07 +00006748- Issue #2776: fixed small issue when handling an URL with double slash
6749 after a 302 response in the case of not going through a proxy.
6750
Antoine Pitroub90a8be2008-08-15 21:03:21 +00006751- Issue #2676: in the email package, content-type parsing was hanging on
6752 pathological input because of quadratic or exponential behaviour of a
6753 regular expression.
6754
Antoine Pitrou11ec65d2008-08-14 21:04:30 +00006755- Issue #3476: binary buffered reading through the new "io" library is now
6756 thread-safe.
6757
Brett Cannonbf3157b2008-08-14 05:00:03 +00006758- Silence the DeprecationWarning of rfc822 when it is imported by mimetools
6759 since mimetools itself is deprecated. Because modules are cached, all
6760 subsequent imports of rfc822 will not raise a visible DeprecationWarning.
6761
Antoine Pitrou9fcd4b32008-08-11 17:21:36 +00006762- Issue #3134: shutil referenced undefined WindowsError symbol.
6763
Robert Schuppenies14646332008-08-10 11:01:53 +00006764- Issue #1342811: Fix leak in Tkinter.Menu.delete. Commands associated to
6765 menu entries were not deleted.
6766
Brett Cannon83e81842008-08-09 23:30:55 +00006767- Copied the implementation of reduce() to _functools.reduce() to have a
6768 version that did not raise a DeprecationWarning under -3.
6769
Antoine Pitrou76b8bee2008-08-09 17:27:23 +00006770- Issue #3205: When iterating over a BZ2File fails allocating memory, raise
6771 a MemoryError rather than silently stop the iteration.
6772
Guido van Rossum59ce9012008-08-09 14:55:34 +00006773- Issue #3487: sre "bytecode" validator. Passing invalid "re-bytecode"
6774 to _sre.compile() will now be rejected. This should not affect anybody
6775 since the re.compile() function never generates invalid re-bytecode.
6776
Skip Montanaroa032bf42008-08-08 22:52:51 +00006777- Issue #3436: Make csv.DictReader's fieldnames attribute a property so that
6778 upon first access it can be automatically initialized from the csv file if
6779 it wasn't initialized during instantiation.
6780
Brett Cannon3aa2a492008-08-06 22:28:09 +00006781- Issue #2338: Create imp.reload() to help with transitioning to Python 3.0 as
6782 the reload() built-in has been removed.
6783
Brett Cannon7e30b672008-08-04 21:52:25 +00006784- Changed code in the following modules/packages to remove warnings raised
Brett Cannonc1b76e42008-08-09 23:06:16 +00006785 while running under the ``-3`` flag: aifc, asynchat, asyncore, bdb, bsddb,

Antoine Pitroude781a42008-08-09 12:43:23 +00006796 asking for a specific length. This problem only affected files opened
6797 using the new "io" module, not the built-in open() function.
Benjamin Peterson01a24322008-07-28 23:35:27 +00006798

6806
Georg Brandlf9efabb2008-07-23 15:16:45 +00006807- Deprecate the "ast" parser function aliases.

6821
Antoine Pitrou5fdfa3e2008-07-25 19:42:26 +00006822- Issue #3394: zipfile.writestr sets external attributes when passed a
6823 file name rather than a ZipInfo instance, so files are extracted with
6824 mode 0600 rather than 000 under Unix.
6825
Gregory P. Smitha36f8fe2008-08-04 00:13:29 +00006826- Issue #1857: subprocess.Popen.poll gained an additional _deadstate keyword
6827 argument in python 2.5, this broke code that subclassed Popen to include its
6828 own poll method. Fixed my moving _deadstate to an _internal_poll method.

Nick Coghlan2a0c2b12008-08-04 12:47:17 +00006841- Issue #643841: The language reference now provides more detailed
6842 coverage of the lookup process for special methods. The disclaimers
6843 regarding lack of coverage of new-style classes have also been

6849
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00006850*Release date: 17-Jul-2008*

6853-----------------
6854
Georg Brandl3e483f62008-07-16 22:57:41 +00006855- Issue #3156: Fix inconsistent behavior of the bytearray type: all
6856 its methods now allow for items objects that can be converted to
6857 an integer using operator.index().
6858
Mark Dickinson64b7e502008-07-16 09:40:03 +00006859- Issue #3360: Fix incorrect parsing of '020000000000.0', which
6860 produced a ValueError instead of giving the correct float.
6861
Eric Smitha5fa5a22008-07-16 00:11:49 +00006862- Issue #3083: Add alternate (#) formatting for bin, oct, hex output
6863 for str.format(). This adds the prefix 0b, 0o, or 0x, respectively.
6864
Mark Dickinson7103aa42008-07-15 19:08:33 +00006865- Issue #3008: the float type has a new instance method 'float.hex'
6866 and a new class method 'float.fromhex' to convert floating-point
6867 numbers to and from hexadecimal strings, respectively.
6868
Nick Coghlan6d6bd442008-07-15 15:40:22 +00006869- Issue #2235: __hash__ is once again inherited by default. To allow
6870 collections.Hashable to remain meaningful in the presence of the
6871 default hash implementation (object.__hash__), it is now possible
6872 to explicit block inheritance of hash by setting __hash__=None at
6873 the Python level, or tp_hash=PyObject_HashNotImplemented at the C
6874 level.
6875
Nick Coghlanb028f502008-07-13 14:52:36 +00006876- Issue #3221: Issue a RuntimeWarning instead of raising SystemError if
6877 the parent module cannot be found while performing an absolute import.
6878 This means that an incorrectly defined __package__ attribute will
6879 now only prevent relative imports in that module rather than causing
6880 all imports from that module to fail.
6881
Nick Coghlan14ff9942008-07-08 14:21:42 +00006882- Issue #2517: Allow unicode messages in Exceptions again by correctly
6883 bypassing the instance dictionary when looking up __unicode__ on
6884 new-style classes.

6887 set to a custom object whose write() method happens to install
6888 another file in sys.stdout.

Amaury Forgeot d'Arc1f40c8a2008-06-30 22:42:40 +00006890- Issue #3088: Corrected a race condition in classes derived from
6891 threading.local: the first member set by a thread could be saved in
6892 another thread's dictionary.
6893
Mark Dickinson1ec2fcd2008-06-20 14:53:43 +00006894- Issue #3004: Minor change to slice.indices(): the start and stop
6895 arguments are now treated identically, making the behaviour easier
6896 to describe and understand. For example, slice(None, -10,
6897 1).indices(9) now returns (0, 0, 1) instead of (0, -1, 1), and
6898 slice(None, 10, -1).indices(10) returns (9, 9, -1) instead of (9,
6899 10, -1).
6900
Georg Brandl278fc502008-07-19 12:46:12 +00006901- Issue #3219: Calling a function with repeated keyword arguments,
6902 f(a=2, a=23), would not cause a syntax error. This was a regression
6903 from 2.4 caused by the switch to the new compiler.
Benjamin Peterson175e4d92008-07-01 19:34:52 +00006904
Georg Brandl278fc502008-07-19 12:46:12 +00006905- Issue #2862: Make int and float freelist management consistent with
6906 other freelists. Changes their CompactFreeList apis into
6907 ClearFreeList apis and calls them via gc.collect().

6913 api functions without holding the GIL, which could lead to a fatal
6914 error when they failed.
6915
Martin v. Löwisaabf4042008-08-02 07:20:25 +00006916- Issue #799428: Fix Tkinter.Misc._nametowidget to unwrap Tcl command objects.

Raymond Hettinger3cd1e422008-07-10 14:03:19 +00006940
Amaury Forgeot d'Arc0f7cddc2008-07-06 21:34:39 +00006941- Issue #839496: SimpleHTTPServer used to open text files in text mode. This is
6942 both unnecessary (HTTP allows text content to be sent in several forms) and
Andrew M. Kuchlingcc3f2b12008-07-10 14:43:31 +00006943 wrong because the actual transmitted size could differ from the
Amaury Forgeot d'Arc0f7cddc2008-07-06 21:34:39 +00006944 content-length. The problem had been corrected in the 2.4 branch, but never
6945 merged into trunk.

Nick Coghlanc060b0e2008-07-02 13:09:19 +00006960- Issue #3190: Pydoc now hides the automatic module attribute __package__ (the
6961 handling is now the same as that of other special attributes like __name__).
6962
Brett Cannon8bb8fa52008-07-02 01:57:08 +00006963- Issue #2885 (partial): The urllib.urlopen() function has been deprecated for

7417 using the 'warning's machinery in such places as the parser where
7418 use of pure Python code is not possible. Both the ``showarning()``
7419 and ``formatwarning()`` gain an optional 'line' argument which is
7420 not called by default for backwards-compatibility reasons. Setting
7421 ``warnings.showwarning()`` to an implementation that lacks support
7422 for the ``line`` argument will raise a DeprecationWarning.

Georg Brandl3ee81df2008-05-17 18:14:43 +00007485- Issue #2550: The approach used by client/server code for obtaining
7486 ports to listen on in network-oriented tests has been refined in an
7487 effort to facilitate running multiple instances of the entire
7488 regression test suite in parallel without issue.
7489 test_support.bind_port() has been fixed such that it will always
7490 return a unique port -- which wasn't always the case with the
7491 previous implementation, especially if socket options had been set
7492 that affected address reuse (i.e. SO_REUSEADDR, SO_REUSEPORT). The
7493 new implementation of bind_port() will actually raise an exception
7494 if it is passed an AF_INET/SOCK_STREAM socket with either the
7495 SO_REUSEADDR or SO_REUSEPORT socket option set. Furthermore, if
7496 available, bind_port() will set the SO_EXCLUSIVEADDRUSE option on
7497 the socket it's been passed. This currently only applies to
7498 Windows. This option prevents any other sockets from binding to the
7499 host/port we've bound to, thus removing the possibility of the
7500 'non-deterministic' behaviour, as Microsoft puts it, that occurs
7501 when a second SOCK_STREAM socket binds and accepts to a host/port
7502 that's already been bound by another socket. The optional preferred
7503 port parameter to bind_port() has been removed. Under no
7504 circumstances should tests be hard coding ports!
7505
7506 test_support.find_unused_port() has also been introduced, which will
7507 pass a temporary socket object to bind_port() in order to obtain an
7508 unused port. The temporary socket object is then closed and
7509 deleted, and the port is returned. This method should only be used
7510 for obtaining an unused port in order to pass to an external program
7511 (i.e. the -accept [port] argument to openssl's s_server mode) or as
7512 a parameter to a server-oriented class that doesn't give you direct
7513 access to the underlying socket used.
7514
7515 Finally, test_support.HOST has been introduced, which should be used
7516 for the host argument of any relevant socket calls (i.e. bind and
7517 connect).
Trent Nelsone41b0062008-04-08 23:47:30 +00007518
7519 The following tests were updated to following the new conventions:
Georg Brandl3ee81df2008-05-17 18:14:43 +00007520 test_socket, test_smtplib, test_asyncore, test_ssl, test_httplib,

7522 test_asynchat and test_socket_ssl.
7523
Georg Brandl3ee81df2008-05-17 18:14:43 +00007524 It is now possible for multiple instances of the regression test
7525 suite to run in parallel without issue.

Eric Smitha73fbe72008-02-23 03:09:44 +00007804- Added the future_builtins module, which contains hex() and oct().
7805 These are the PEP 3127 version of these functions, designed to be
7806 compatible with the hex() and oct() builtins from Python 3.0. They
7807 differ slightly in their output formats from the existing, unchanged
7808 Python 2.6 builtins. The expected usage of the future_builtins
7809 module is:
7810 from future_builtins import hex, oct
7811
Eric Smith7ef40bf2008-02-20 23:34:22 +00007812- Issue #1600: Modifed PyOS_ascii_formatd to use at most 2 digit
7813 exponents for exponents with absolute value < 100. Follows C99
7814 standard. This is a change on Windows, which would use 3 digits.
7815 Also, added 'n' to the formats that PyOS_ascii_formatd understands,
7816 so that any alterations it does to the resulting string will be
7817 available in stringlib/formatter.h (for float.__format__).
7818
Eric Smith5a3c1352008-02-19 13:21:56 +00007819- Implemented PEP 3101, Advanced String Formatting. This adds a new
7820 builtin format(); a format() method for str and unicode; a
7821 __format__() method to object, str, unicode, int, long, float, and
7822 datetime; the class string.Formatter; and the C API
7823 PyObject_Format().
7824
Georg Brandl3ee81df2008-05-17 18:14:43 +00007825- Fixed several potential crashes, all caused by specially crafted
7826 __del__ methods exploiting objects in temporarily inconsistent
7827 state.
Amaury Forgeot d'Arc632fad32008-02-16 20:55:24 +00007828
Vinay Sajipb7edfc42008-04-02 21:10:23 +00007829- Issue #2115: Important speedup in setting __slot__ attributes. Also

7837 in order to allow pymalloc to free more arenas. Python may give back
7838 memory to the OS earlier.
Christian Heimes3b718a72008-02-14 12:47:33 +00007839
Georg Brandl3ee81df2008-05-17 18:14:43 +00007840- Issue #2045: Fix an infinite recursion triggered when printing a
7841 subclass of collections.defaultdict, if its default_factory is set
7842 to a bound method.
Amaury Forgeot d'Arcb01aa432008-02-08 00:56:02 +00007843
Christian Heimesf75dbef2008-02-08 00:11:31 +00007844- Fixed a minor memory leak in dictobject.c. The content of the free
7845 list was not freed on interpreter shutdown.
7846
Georg Brandl21e99f42010-03-07 15:23:59 +00007847- Limit free list of method and built-in function objects to 256

7851 functions ``PyInt_CompactFreeList`` and ``PyFloat_CompactFreeList``
Christian Heimes422051a2008-02-04 18:00:12 +00007852 to compact the internal free lists of pre-allocted ints and floats.
7853
Georg Brandl3ee81df2008-05-17 18:14:43 +00007854- Issue #1983: Fixed return type of fork(), fork1() and forkpty()
7855 calls. Python expected the return type int but the fork familie
7856 returns pi_t.
Christian Heimes951cc0f2008-01-31 23:08:23 +00007857

Georg Brandl3ee81df2008-05-17 18:14:43 +00007870- Patch #1473257: generator objects gain a gi_code attribute. This is
7871 the same object as the func_code attribute of the function that
7872 produced the generator.
Georg Brandl0cdf9a32008-01-26 14:14:20 +00007873
Georg Brandl3ee81df2008-05-17 18:14:43 +00007874- Issue #1920: "while 0" statements were completely removed by the
7875 compiler, even in the presence of an "else" clause, which is
7876 supposed to be run when the condition is false. Now the compiler
7877 correctly emits bytecode for the "else" suite.
Amaury Forgeot d'Arc31eaafe2008-01-24 22:59:25 +00007878

Georg Brandl3ee81df2008-05-17 18:14:43 +00007905- Objects/structseq.c: Implemented new structseq representation. The
7906 patch makes structseqs (e.g. the return value of os.stat) more
7907 readable.
Christian Heimes9c201962008-01-14 03:33:52 +00007908
Georg Brandl3ee81df2008-05-17 18:14:43 +00007909- Patch #1700288: added a type attribute cache that caches method
7910 accesses, resulting in speedups in heavily object-oriented code.
Amaury Forgeot d'Arce4c270c2008-01-14 00:29:41 +00007911
Neal Norwitz3fc15b82008-01-10 05:42:58 +00007912- Bug #1776: __import__() no longer accepts filenames on any platform.
7913 The first parameter to __import__() must be a valid module name.

Georg Brandlaed6c662008-01-07 17:25:53 +00007915- Patch #1668: renamed THREADDEBUG envvar to PYTHONTHREADDEBUG.
7916
Georg Brandl3ee81df2008-05-17 18:14:43 +00007917- Patch #602345: Add -B command line option, PYTHONDONTWRITEBYTECODE
7918 envvar and sys.dont_write_bytecode attribute. All these can be set
7919 to forbid Python to attempt to write compiled bytecode files.
Georg Brandl2da0fce2008-01-07 17:09:35 +00007920
Georg Brandl3ee81df2008-05-17 18:14:43 +00007921- Improve some exception messages when Windows fails to load an
7922 extension module. Now we get for example '%1 is not a valid Win32
7923 application' instead of 'error code 193'.
Amaury Forgeot d'Arce0b76952008-01-04 02:04:15 +00007924

Christian Heimes0a8143f2007-12-18 23:22:54 +00007930- Issue #1635: Platform independent creation and representation of NaN
Georg Brandl3ee81df2008-05-17 18:14:43 +00007931 and INF. float("nan"), float("inf") and float("-inf") now work on
7932 every platform with IEEE 754 semantics.

Georg Brandl3ee81df2008-05-17 18:14:43 +00007934- Compiler now generates simpler and faster code for dictionary
7935 literals. The oparg for BUILD_MAP now indicates an estimated
7936 dictionary size. There is a new opcode, STORE_MAP, for adding
7937 entries to the dictionary.

Georg Brandl3ee81df2008-05-17 18:14:43 +00007966- Patch #1739468: Directories and zipfiles containing a __main__.py
7967 file can now be directly executed by passing their name to the
7968 interpreter. The directory/zipfile is automatically inserted as the
7969 first entry in sys.path.

Georg Brandl3ee81df2008-05-17 18:14:43 +00007971- Issue #1265: Fix a problem with sys.settrace, if the tracing
7972 function uses a generator expression when at the same time the
7973 executed code is closing a paused generator.
Amaury Forgeot d'Arc0d75f092007-11-13 21:54:28 +00007974
Raymond Hettinger1760c8a2007-11-08 02:52:43 +00007975- sets and frozensets now have an isdisjoint() method.
7976

7980
Georg Brandl21e99f42010-03-07 15:23:59 +00007981- The enumerate() built-in function is no longer bounded to sequences
Georg Brandl3ee81df2008-05-17 18:14:43 +00007982 smaller than LONG_MAX. Formerly, it raised an OverflowError. Now,
7983 automatically shifts from ints to longs.
Raymond Hettinger8f669372007-10-03 21:18:11 +00007984
Georg Brandl3ee81df2008-05-17 18:14:43 +00007985- Issue #1686386: Tuple's tp_repr did not take into account the
7986 possibility of having a self-referential tuple, which is possible
7987 from C code. Nor did object's tp_str consider that a type's tp_str
7988 could do something that could lead to an inifinite recursion.
7989 Py_ReprEnter() and Py_EnterRecursiveCall(), respectively, fixed the
7990 issues.
Brett Cannon0b14f242007-09-30 19:45:10 +00007991
Georg Brandl3ee81df2008-05-17 18:14:43 +00007992- Issue #1164: It was possible to trigger deadlock when using the
7993 'print' statement to write to a file since the GIL was not released
7994 as needed. Now PyObject_Print() does the right thing along with
7995 various tp_print implementations of the built-in types and those in
7996 the collections module.
Brett Cannon01531592007-09-17 03:28:34 +00007997
Georg Brandl3ee81df2008-05-17 18:14:43 +00007998- Issue #1147: Exceptions were directly allowing string exceptions in
7999 their throw() method even though string exceptions no longer
8000 allowed.

Brett Cannona0c05512007-09-10 21:38:27 +00008004
Brett Cannon1e534b52007-09-07 04:18:30 +00008005- Issue #1202533: Fix infinite recursion calls triggered by calls to
Georg Brandl3ee81df2008-05-17 18:14:43 +00008006 PyObject_Call() never calling back out to Python code to trigger
8007 recursion depth updates/checks. Required the creation of a static
8008 RuntimeError instance in case normalizing an exception put the
8009 recursion check value past its limit. Fixes crashers
8010 infinite_rec_(1|2|4|5).py.
Brett Cannon1e534b52007-09-07 04:18:30 +00008011

Neal Norwitz0ac60192007-05-27 04:08:54 +00008025- Add new attribute names for function objects. All the func_* become
Georg Brandl3ee81df2008-05-17 18:14:43 +00008026 __*__ attributes. (Some already existed, e.g., __doc__ and
8027 __name__.)
Neal Norwitz0ac60192007-05-27 04:08:54 +00008028
Neal Norwitz8b2bfbc2007-05-23 06:35:32 +00008029- Add -3 option to the interpreter to warn about features that are
8030 deprecated and will be changed/removed in Python 3.0.
8031
Georg Brandl2134e752007-05-21 20:34:16 +00008032- Patch #1686487: you can now pass any mapping after '**' in function
8033 calls.
8034
Collin Winter62903052007-05-18 23:11:24 +00008035- except clauses may now be spelled either "except E, target:" or
Georg Brandl3ee81df2008-05-17 18:14:43 +00008036 "except E as target:". This is to provide forwards compatibility
8037 with Python 3.0.
Collin Winter62903052007-05-18 23:11:24 +00008038
Brett Cannon229cee22007-05-05 01:34:02 +00008039- Deprecate BaseException.message as per PEP 352.

Vinay Sajip8549ce32007-05-06 17:53:37 +00008044- When __slots__ are set to a unicode string, make it work the same as
Neal Norwitzcbd9ee62007-04-14 05:25:50 +00008045 setting a plain string, ie don't expand to single letter identifiers.
8046
Raymond Hettinger13936692007-04-11 18:40:58 +00008047- Request #1191699: Slices can now be pickled.
8048
Raymond Hettinger4db5fe92007-04-12 04:10:00 +00008049- Request #1193128: str.translate() now allows a None argument for
8050 translations that only remove characters without re-mapping the
8051 remaining characters.
8052
Georg Brandl5cb76c12007-03-21 09:00:39 +00008053- Patch #1682205: a TypeError while unpacking an iterable is no longer

8055
Neal Norwitzaa754b72007-03-21 06:39:48 +00008056- Remove unused file Python/fmod.c.
8057
Guido van Rossum143b5642007-03-23 04:58:42 +00008058- Bug #1683368: The object.__init__() and object.__new__() methods are
8059 now stricter in rejecting excess arguments. The only time when
8060 either allows excess arguments is when it is not overridden and the
8061 other one is. For backwards compatibility, when both are
8062 overridden, it is a deprecation warning (for now; maybe a Py3k
Guido van Rossum234b1ff2007-03-23 19:39:01 +00008063 warning later). Also, type.__init__() insists on the same signature
8064 as supported by type.__new__().
Guido van Rossum143b5642007-03-23 04:58:42 +00008065
Georg Brandl3ee81df2008-05-17 18:14:43 +00008066- Patch #1675423: PyComplex_AsCComplex() now tries to convert an
8067 object to complex using its __complex__() method before falling back
8068 to the __float__() method. Therefore, the functions in the cmath
8069 module now can operate on objects that define a __complex__()
8070 method.
Georg Brandl2b869942007-03-17 16:08:45 +00008071
Georg Brandl3ee81df2008-05-17 18:14:43 +00008072- Patch #1623563: allow __class__ assignment for classes with
8073 __slots__. The old and the new class are still required to have the
8074 same slot names.
Žiga Seilnacht6f2d09c2007-03-16 11:59:38 +00008075

8087
Georg Brandl7b9c5552007-03-12 14:30:05 +00008088- Bug #1678647: write a newline after printing an exception in any
8089 case, even when converting the value to a string failed.
8090
Georg Brandl871f1bc2007-03-12 13:17:36 +00008091- The dir() function has been extended to call the __dir__() method on
Georg Brandl3ee81df2008-05-17 18:14:43 +00008092 its argument, if it exists. If not, it will work like before. This
8093 allows customizing the output of dir() in the presence of a
8094 __getattr__().

8103 parthensized forms. This means complex(repr(x)) now works instead of
8104 raising a ValueError.
Collin Wintere38051d2007-03-09 20:33:07 +00008105
Georg Brandlaa2321b2007-03-07 00:40:28 +00008106- Patch #703779: unset __file__ in __main__ after running a file. This
Georg Brandl3ee81df2008-05-17 18:14:43 +00008107 makes the filenames the warning module prints much more sensible
8108 when a PYTHONSTARTUP file is used.

Georg Brandl0fca97a2007-03-05 22:28:08 +00008121- Patch #1674228: when assigning a slice (old-style), check for the
8122 sq_ass_slice instead of the sq_slice slot.
8123
Georg Brandl3ee81df2008-05-17 18:14:43 +00008124- When printing an unraisable error, don't print exceptions. before
8125 the name. This duplicates the behavior whening normally printing
8126 exceptions.

Facundo Batistab6a5c9d2007-03-29 18:22:35 +00008628- Added a timeout parameter to the constructor of other protocols
8629 (telnetlib, ftplib, smtplib and poplib). This is second part of the
8630 work started with create_connection() and timeout in httplib, and
8631 closes patch #723312.
8632
Vinay Sajip8549ce32007-05-06 17:53:37 +00008633- Patch #1676823: Added create_connection() to socket.py, which may be
8634 called with a timeout, and use it from httplib (whose HTTPConnection
Facundo Batista70f996b2007-05-21 17:32:32 +00008635 and HTTPSConnection now accept an optional timeout).
Facundo Batista07c78be2007-03-23 18:54:07 +00008636
Martin v. Löwis0af33882007-03-23 13:27:15 +00008637- Bug #978833: Revert r50844, as it broke _socketobject.dup.

Georg Brandl3ee81df2008-05-17 18:14:43 +00008644- Patch #1273829: os.walk() now has a "followlinks" parameter. If set
8645 to True (which is not the default), it visits symlinks pointing to

8649 GNOME or KDE browser, depending on whether there is a session of one

8657
Georg Brandlf66b6032007-03-14 08:27:52 +00008658- Bug #767111: fix long-standing bug in urllib which caused an
Georg Brandl3ee81df2008-05-17 18:14:43 +00008659 AttributeError instead of an IOError when the server's response
8660 didn't contain a valid HTTP status line.
Georg Brandlf66b6032007-03-14 08:27:52 +00008661
Georg Brandl3ee81df2008-05-17 18:14:43 +00008662- Patch #957650: "%var%" environment variable references are now
8663 properly expanded in ntpath.expandvars(), also "~user" home

Georg Brandl03b90d82007-03-13 22:07:36 +00008665
Georg Brandl3ee81df2008-05-17 18:14:43 +00008666- Patch #1429539: pdb now correctly initializes the __main__ module
8667 for the debugged script, which means that imports from __main__ work
Georg Brandlb6ae6aa2007-03-13 21:58:44 +00008668 correctly now.
8669
Georg Brandlbad6f192007-03-13 21:32:56 +00008670- The nonobvious commands.getstatus() function is now deprecated.

8676
Georg Brandl3ee81df2008-05-17 18:14:43 +00008677- Patch #1530482: add pydoc.render_doc() which returns the
8678 documentation for a thing instead of paging it to stdout, which
8679 pydoc.doc() does.

8687 parameter which can be set to False to prevent the default
8688 delete-on-close behavior.
Georg Brandl35ef9c12007-03-13 18:31:49 +00008689
Georg Brandl9e6b4702007-03-13 18:15:41 +00008690- Patch #1581073: add a flag to textwrap that prevents the dropping of
8691 whitespace while wrapping.
8692
Georg Brandl92a6bae2007-03-13 17:43:32 +00008693- Patch #1603688: ConfigParser.SafeConfigParser now checks values that
Georg Brandl3ee81df2008-05-17 18:14:43 +00008694 are set for invalid interpolation sequences that would lead to
8695 errors on reading back those values.
Georg Brandl92a6bae2007-03-13 17:43:32 +00008696

8709
Georg Brandl94fe3f52007-03-13 09:32:11 +00008710- Patch #1635454: the csv.DictWriter class now includes the offending
Georg Brandl3ee81df2008-05-17 18:14:43 +00008711 field names in its exception message if you try to write a record
8712 with a dictionary containing fields not in the CSV field names list.

8738 returned string up to the first NUL character.
8739

8749
Georg Brandl3ee81df2008-05-17 18:14:43 +00008750- unittest now verifies more of its assumptions. In particular,
8751 TestCase and TestSuite subclasses (not instances) are no longer
8752 accepted in TestSuite.addTest(). This should cause no
8753 incompatibility since it never made sense with ordinary subclasses
8754 -- the failure just occurred later, with a more cumbersome
8755 exception.

8764 given a unicode argument and os.listdir() returns unicode filenames.
8765
Georg Brandl3ee81df2008-05-17 18:14:43 +00008766- Patch #1673619: setup.py identifies extension modules it doesn't

9110 the behavior into line with that for list.__init__().

Georg Brandl3ee81df2008-05-17 18:14:43 +00009119- Marshal.dumps() now expects exact type matches for int, long, float,
9120 complex, tuple, list, dict, set, and frozenset. Formerly, it would
9121 silently miscode subclasses of those types. Now, it raises a
9122 ValueError instead.

Gregory P. Smithec10a4a2007-11-05 02:32:26 +00009137- pybsddb.sf.net Bug #477182: Load the database flags at database open
Georg Brandl3ee81df2008-05-17 18:14:43 +00009138 time so that opening a database previously created with the DB_DUP
9139 or DB_DUPSORT flag set will keep the proper behavior on subsequent
9140 opens. Specifically: dictionary assignment to a DB object will
9141 replace all values for a given key when the database allows
9142 duplicate values. DB users should use DB.put(k, v) when they want
9143 to store duplicates; not DB[k] = v.

9150 characters with ASCII value less than 32. Also, it correctly quotes
9151 dots only if they occur on a single line, as opposed to the previous
9152 behavior of quoting dots if they are the second character of any
9153 line.
