1280 In particular, fix extension module build failures when trying to use
1281 32-bit-only installer Pythons on systems with Xcode 4 (currently
1282 OS X 10.8, 10.7, and optionally 10.6).
1283 * Backport 3.3.0 fixes to 2.7 branch (for release in 2.7.4)
1284 * Since Xcode 4 removes ppc support, extension module builds now
1285 check for ppc compiler support and by default remove ppc and
1286 ppc64 archs when they are not available.
1287 * Extension module builds now revert to using system installed
1288 headers and libs (/usr and /System/Library) if the SDK used
1289 to build the interpreter is not installed or has moved.
1290 * Try to avoid building extension modules with deprecated
1291 and problematic Apple llvm-gcc compiler. If original compiler
1292 is not available, use clang instead by default.

1724 Distutils-based packages with C extension modules may fail because
1725 Apple has removed gcc-4.2, the version used to build python.org
1726 64-bit/32-bit Pythons. If the user does not explicitly override
1727 the default C compiler by setting the CC environment variable,
1728 Distutils will now attempt to compile extension modules with clang
1729 if gcc-4.2 is required but not found. Also as a convenience, if
1730 the user does explicitly set CC, substitute its value as the default
1731 compiler in the Distutils LDSHARED configuration variable for OS X.
1732 (Note, the python.org 32-bit-only Pythons use gcc-4.0 and the 10.4u
1733 SDK, neither of which are available in Xcode 4. This change does not
1734 attempt to override settings to support their use with Xcode 4.)

Ned Deily87e82bb2011-06-28 19:52:59 -07001984- Issue #9516: On Mac OS X, change Distutils to no longer globally attempt to
1985 check or set the MACOSX_DEPLOYMENT_TARGET environment variable for the
1986 interpreter process. This could cause failures in non-Distutils subprocesses
1987 and was unreliable since tests or user programs could modify the interpreter
Ezio Melotti302ad8d2013-01-19 19:44:58 +02001988 environment after Distutils set it. Instead, have Distutils set the
Ned Deily87e82bb2011-06-28 19:52:59 -07001989 deployment target only in the environment of each build subprocess. It is
1990 still possible to globally override the default by setting
1991 MACOSX_DEPLOYMENT_TARGET before launching the interpreter; its value must be
1992 greater or equal to the default value, the value with which the interpreter
1993 was built.

2023 the ticker doesn't have to wind down to zero from the old starting point
2024 before the new interval takes effect. And if the user increases the
2025 interval, it makes sure the new limit takes effect right away rather have an
2026 early task switch before recognizing the new interval.

Raymond Hettinger20397532010-09-12 02:11:45 +00003006- Issue #9825: removed __del__ from the definition of collections.OrderedDict.
3007 This prevents user-created self-referencing ordered dictionaries from
3008 becoming permanently uncollectable GC garbage. The downside is that
3009 removing __del__ means that the internal doubly-linked list has to wait for
3010 GC collection rather than freeing memory immediately when the refcnt drops
3011 to zero.
3012
Raymond Hettingerffd2a422010-09-10 10:47:22 +00003013- Issue #9816: random.Random.jumpahead(n) did not produce a sufficiently

3016
Antoine Pitrouc818ed42010-09-07 21:40:25 +00003017- Issue #9792: In case of connection failure, socket.create_connection()
3018 would swallow the exception and raise a new one, making it impossible
3019 to fetch the original errno, or to filter timeout errors. Now the
3020 original error is re-raised.
3021
Antoine Pitrouf4f61712010-09-07 16:34:47 +00003022- Issue #9758: When fcntl.ioctl() was called with mutable_flag set to True,

3024 be updated back after the system call. Original patch by Brian Brazil.

3041
R. David Murray7c4bf552010-08-25 01:45:57 +00003042- Issue #1194222: email.utils.parsedate now returns RFC2822 compliant four
3043 character years even if the message contains RFC822 two character years.
3044
Daniel Stutzbach91287322010-08-24 21:09:30 +00003045- Issue #8750: Fixed MutableSet's methods to correctly handle

3058
Antoine Pitrou3ebaed62010-08-21 19:17:25 +00003059- Issue #9617: Signals received during a low-level write operation aren't
3060 ignored by the buffered IO layer anymore.
3061
Benjamin Peterson52c36052010-08-21 03:03:22 +00003062- Issue #2521: Use weakrefs on for caching in the abc module, so that classes

3064
Raymond Hettingera54b2da2010-08-17 19:03:06 +00003065- Issue #9626: the view methods for collections.OrderedDict() were returning

Antoine Pitroucb4f47c2010-08-11 13:40:17 +00003077- Issue #9550: a BufferedReader could issue an additional read when the
3078 original read request had been satisfied, which could block indefinitely
3079 when the underlying raw IO channel was e.g. a socket. Report and original
3080 patch by Jason V. Miller.
3081
Fred Drake0a1fa0e2010-08-10 13:09:54 +00003082- Issue #9551: Don't raise TypeError when setting the value to None for

3736 indefinitely if the other end didn't respond.
3737
Georg Brandlfee0f442010-05-22 21:26:21 +00003738- The do_handshake() method of SSL objects now adjusts the blocking mode of the

Georg Brandlfee0f442010-05-22 21:26:21 +00003749- Issue #8451: Syslog module now uses basename(sys.argv[0]) instead of the
3750 string "python" as the *ident*. openlog() arguments are all optional and
3751 keywords.

Mark Dickinsond2f3e3f2010-05-05 22:23:58 +00003831 (Optimization was unintentionally turned on in gcc --with-pydebug builds in

Philip Jenveyaebbaeb2010-04-06 23:24:45 +00003856- Issue #7301: Add environment variable $PYTHONWARNINGS.
3857
Benjamin Peterson3a1dfa22010-04-06 21:50:00 +00003858- Issue #8329: Don't return the same lists from select.select when no fds are
3859 changed.
3860
Georg Brandlfee0f442010-05-22 21:26:21 +00003861- Issue #8259: ``1L << (2**31)`` no longer produces an 'outrageous shift error'
Mark Dickinson82791672010-04-06 16:47:55 +00003862 on 64-bit machines. The shift count for either left or right shift is
3863 permitted to be up to sys.maxsize.
3864
Benjamin Peterson4ceeeb02010-04-03 22:48:51 +00003865- Ensure that tokenization of identifiers is not affected by locale.

Georg Brandlfee0f442010-05-22 21:26:21 +00003871- Issue #7994: Issue a PendingDeprecationWarning if object.__format__ is called
3872 with a non-empty format string. This is an effort to future-proof user
3873 code. If a derived class does not currently implement __format__ but later
3874 adds its own __format__, it would most likely break user code that had
Antoine Pitrou01a196a2011-01-02 20:05:11 +00003875 supplied a format string. This will be changed to a DeprecationWarning in
Georg Brandlfee0f442010-05-22 21:26:21 +00003876 Python 3.3 and it will be an error in Python 3.4.

Georg Brandlfee0f442010-05-22 21:26:21 +00003909- Issue #8257: The Decimal construct now accepts a float instance directly,
3910 converting that float to a Decimal of equal value:
Mark Dickinson8a950712010-04-03 15:47:46 +00003911

Georg Brandlfee0f442010-05-22 21:26:21 +00003926- Issue #7279: Comparisons involving a Decimal signaling NaN now signal
3927 InvalidOperation instead of returning False. (Comparisons involving a quiet
3928 NaN are unchanged.) Also, Decimal quiet NaNs are now hashable; Decimal
3929 signaling NaNs remain unhashable.
Mark Dickinsone096e822010-04-02 10:17:07 +00003930
Georg Brandlfee0f442010-05-22 21:26:21 +00003931- Issue #2531: Comparison operations between floats and Decimal instances now
3932 return a result based on the numeric values of the operands; previously they
3933 returned an arbitrary result based on the relative ordering of id(float) and
3934 id(Decimal).

Georg Brandlfee0f442010-05-22 21:26:21 +00003948- Comparisons using one of <, <=, >, >= between a complex instance and a
3949 Fractions instance now raise TypeError instead of returning True/False. This
3950 makes Fraction <=> complex comparisons consistent with int <=> complex, float
3951 <=> complex, and complex <=> complex comparisons.

4314 could crash in many places because of the ``PyByteArray_AS_STRING()`` macro
4315 returning NULL. The macro now returns a statically allocated empty string

Antoine Pitroud840e512010-02-04 20:20:18 +00004361- Issue #4772: Raise a ValueError when an unknown Bluetooth protocol is
Georg Brandlba83f822010-03-14 09:50:54 +00004362 specified, rather than fall through to AF_PACKET (in the ``socket`` module).

Antoine Pitrouf3fa0742010-01-31 22:26:04 +00004368- Issue #6939: Fix file I/O objects in the `io` module to keep the original
Georg Brandlba83f822010-03-14 09:50:54 +00004369 file position when calling `truncate()`. It would previously change the file
4370 position to the given argument, which goes against the tradition of
Antoine Pitrouf3fa0742010-01-31 22:26:04 +00004371 ftruncate() and other truncation APIs. Patch by Pascal Chambon.
4372

4374 class used to represent files stored inside an archive. The new
4375 implementation is significantly faster and can be wrapped in a
4376 ``io.BufferedReader`` object for more speedups. It also solves an issue
4377 where interleaved calls to ``read()`` and ``readline()`` give wrong results.

Georg Brandlba83f822010-03-14 09:50:54 +00004388- Issue #7748: Since unicode values are supported for some metadata options in
4389 Distutils, the DistributionMetadata get_* methods will now return an utf-8
4390 encoded string for them. This ensures that the upload and register commands
4391 send the correct values to PyPI without any error.

Benjamin Peterson4f51baf2009-12-05 18:40:02 +00004460What's New in Python 2.7 alpha 2?

4466-----------------
4467
Georg Brandlba83f822010-03-14 09:50:54 +00004468- The ``__complex__()`` method is now looked up on the class of instances to
4469 make it consistent with other special methods.
Benjamin Petersonecdae192010-01-04 00:43:01 +00004470
Antoine Pitrou5b7139a2010-01-02 21:12:58 +00004471- Issue #7462: Implement the stringlib fast search algorithm for the `rfind`,
4472 `rindex`, `rsplit` and `rpartition` methods. Patch by Florent Xicluna.
4473
Mark Dickinson1b34d252010-01-01 17:27:30 +00004474- Issue #5080: A number of functions and methods previously produced a
Georg Brandlba83f822010-03-14 09:50:54 +00004475 DeprecationWarning when passed a float argument where an integer was expected.
4476 These functions and methods now raise TypeError instead. The majority of the
4477 effects of this change are in the extension modules, but some core functions
4478 and methods are affected: notably the 'chr', 'range' and 'xrange' builtins,
4479 and many unicode/str methods.

4490 used to drop the time part of the result.
4491
Georg Brandlba83f822010-03-14 09:50:54 +00004492- Issue #1811: Improve accuracy and cross-platform consistency for true division
4493 of integers: the result of a/b is now correctly rounded for ints a and b (at
4494 least on IEEE 754 platforms), and in particular does not depend on the
4495 internal representation of a long.
Mark Dickinson46572832009-12-27 14:55:57 +00004496
Georg Brandlba83f822010-03-14 09:50:54 +00004497- Issue #6108: ``unicode(exception)`` and ``str(exception)`` should return the
4498 same message when only ``__str__()`` (and not ``__unicode__()``) is overridden
4499 in the subclass.

Ronald Oussoren92919a62009-12-24 13:30:58 +00004502 executables on OSX.
4503
Georg Brandlba83f822010-03-14 09:50:54 +00004504 These executables now work properly with the arch(1) command: ``arch -ppc
4505 python`` will start a universal binary version of python in PPC mode (unlike
4506 previous releases).

Georg Brandlba83f822010-03-14 09:50:54 +00004529 renaming of `cPickle` to `pickle`. The warning was annoying since there's no

Georg Brandlba83f822010-03-14 09:50:54 +00004662- Issue #7117: ``repr(x)`` for a float x returns a result based on the shortest
4663 decimal string that's guaranteed to round back to x under correct rounding
4664 (with round-half-to-even rounding mode). Previously it gave a string based on
4665 rounding x to 17 decimal digits. repr(x) for a complex number behaves
4666 similarly. On platforms where the correctly-rounded strtod and dtoa code is
4667 not supported (see below), repr is unchanged.

Georg Brandlba83f822010-03-14 09:50:54 +00004669- Issue #7117: On almost all platforms: float-to-string and string-to-float
4670 conversions within Python are now correctly rounded. Places these conversions
4671 occur include: str for floats and complex numbers; the float and complex
4672 constructors; old-style and new-style numeric formatting; serialization and
4673 deserialization of floats and complex numbers using marshal, pickle and json;
4674 parsing of float and imaginary literals in Python code; Decimal-to-float
4675 conversion.
Mark Dickinsonb678de82009-11-19 18:41:49 +00004676
Georg Brandlba83f822010-03-14 09:50:54 +00004677 The conversions use a Python-adapted version of David Gay's well-known dtoa.c,
4678 providing correctly-rounded strtod and dtoa C functions. This code is
4679 supported on Windows, and on Unix-like platforms using gcc, icc or suncc as
4680 the C compiler. There may be a small number of platforms on which correct
4681 operation of this code cannot be guaranteed, so the code is not used: notably,
4682 this applies to platforms where the C double format is not IEEE 754 binary64,
4683 and to platforms on x86 hardware where the x87 FPU is set to 64-bit precision
4684 and Python's configure script is unable to determine how to change the FPU

Georg Brandlba83f822010-03-14 09:50:54 +00004688- Issue #7117: Backport round implementation from Python 3.x. ``round()`` now
4689 uses the correctly-rounded string <-> float conversions described above (when
4690 available), and so produces correctly rounded results that will display nicely
4691 under the float repr. There are two related small changes: (1) round now
4692 accepts any class with an ``__index__()`` method for its second argument (but
4693 no longer accepts floats for the second argument), and (2) an excessively
4694 large second integer argument (e.g., ``round(1.234, 10**100)``) no longer
4695 raises an exception.

Antoine Pitrouf8387af2009-03-23 18:41:45 +00004912- Issue #4688: Add a heuristic so that tuples and dicts containing only
Georg Brandlba83f822010-03-14 09:50:54 +00004913 untrackable objects are not tracked by the garbage collector. This can reduce
4914 the size of collections and therefore the garbage collection overhead on
4915 long-running programs, depending on their particular use of datatypes.

5074 this code path is really executed because I cannot move to such directory on

5101 PyUnicode_DecodeUTF8() once, remember the result and output it in a second

Georg Brandlba83f822010-03-14 09:50:54 +00006275 - Packing a float now always gives a Deprecation Warning. Previously it
6276 only warned for 'I', 'L', '*B', '*H', '*I', '*L'.

Georg Brandlba83f822010-03-14 09:50:54 +00006278 - If x is not an int, long or float, then packing x will always result in
6279 struct.error. Previously an x with an __int__ method could be packed by
6280 'b', 'B', 'h', 'H', 'i', 'l', '*b', '*h' ,'*i', '*l', and an x with a
6281 __long__ method could be packed by 'q', 'Q', '*q', '*Q'; for x with
6282 neither __int__ nor __long__, TypeError used to be raised (with a
6283 confusing error message) for 'I', 'L', '*B', '*H', '*I', '*L', and
6284 struct.error in other cases.

6287 argument with an __int__ method can be packed, but use of this feature
6288 triggers a DeprecationWarning.

Amaury Forgeot d'Arc05e34492008-09-10 22:04:45 +00006481- Issue #3743: In a few places, PY_FORMAT_SIZE_T was incorrectly used with

6483 PY_FORMAT_SIZE_T is designed to select the correct format for the OS

Brett Cannon672237d2008-09-09 00:49:16 +00006556 return a list or None rather than a custom object.
6557

Brett Cannon1eaf0742008-09-02 01:25:16 +00006582 warnings.catch_warnings() along with some API cleanup. Expanding the tests
6583 for catch_warnings() also led to an improvement in the raising of a
6584 DeprecationWarning related to warnings.warn_explicit().
6585
Benjamin Peterson973e6c22008-09-01 23:12:58 +00006586- The deprecation warnings for the old camelCase threading API were removed.

6608
Amaury Forgeot d'Arc293924b2008-09-02 23:19:56 +00006609- Issue #2975: When compiling several extension modules with Visual Studio 2008
6610 from the same python interpreter, some environment variables would grow
6611 without limit.
6612
Benjamin Peterson37346b22008-08-23 20:27:43 +00006613- Issue #3643: Added a few more checks to _testcapi to prevent segfaults by
6614 exploitation of poor argument checking.
6615

Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00006650What's New in Python 2.6 beta 3?
6651================================
6652
Barry Warsaw07a4a382008-08-21 01:15:08 +00006653*Release date: 20-Aug-2008*
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00006654
6655Core and Builtins
6656-----------------
6657
Guido van Rossumf8402962008-08-20 15:01:50 +00006658- Issue #1878: Remove Py_TPFLAGS_HAVE_VERSION_TAG from
6659 Py_TPFLAGS_DEFAULT when not building the core. This means 3rd party
6660 extensions do not automatically benefit from the class attribute
6661 cache; they will have to explicitly add Py_TPFLAGS_HAVE_VERSION_TAG
6662 to their tp_flags field if they care. This is a backwards
6663 compatibility feature; in 3.0, all types will use the cache by
6664 default.
6665
Benjamin Petersonf647dc12008-08-20 01:27:30 +00006666- Keyword arguments can now follow starred arguments. (``f(a, *args,
6667 keyword=23)`` is now valid syntax.)
6668
Thomas Heller0ad5ae02008-08-19 19:25:04 +00006669- ctypes function pointers that are COM methods have a boolean True
6670 value again.
6671
Martin v. Löwisf91d46a2008-08-12 14:49:50 +00006672- Issue #3139: Make buffer-interface thread-safe wrt. PyArg_ParseTuple,
6673 by denying s# to parse objects that have a releasebuffer procedure,
6674 and introducing s*.
6675
Georg Brandl1e13ea92008-08-11 09:07:59 +00006676- Issue #3537: Fix an assertion failure when an empty but presized dict
6677 object was stored in the freelist.
6678
Mark Dickinsonb6467572008-08-04 21:30:09 +00006679- Issue #1481296: Make long(float('nan')) and int(float('nan')) raise
6680 ValueError consistently across platforms.
6681
Amaury Forgeot d'Arc39fd6722008-07-31 21:28:03 +00006682- Issue #3479: On platforms where sizeof(int) is smaller than sizeof(long)
6683 (64bit Unix, for example), unichr() would truncate its argument and return
6684 u'\x00' for unichr(2**32). Now it properly raises an OverflowError.
6685
Neal Norwitze7d8be82008-07-31 17:17:14 +00006686- Apply security patches from Apple.
6687
Amaury Forgeot d'Arc246daed2008-07-31 00:42:16 +00006688- Issue #2542: Now that issubclass() may call arbitrary code, ensure that
6689 PyErr_ExceptionMatches returns 0 when an exception occurs there.
6690
Antoine Pitrou92f82162008-07-25 22:22:08 +00006691- Issue #1819: function calls with several named parameters are now on
6692 average 35% faster (as measured by pybench).
6693
Amaury Forgeot d'Arce4921fe2008-07-21 22:00:38 +00006694- Issue #2378: An unexpected UnboundLocalError or NameError could appear when
6695 the python debugger steps into a class statement: the free variables (local
6696 variables defined in an outer scope) would be deleted from the outer scope.
6697
Gregory P. Smith0470bab2008-07-22 04:46:32 +00006698- Issue #2620: Overflow checking when allocating or reallocating memory
6699 was not always being done properly in some python types and extension
6700 modules. PyMem_MALLOC, PyMem_REALLOC, PyMem_NEW and PyMem_RESIZE have
6701 all been updated to perform better checks and places in the code that
6702 would previously leak memory on the error path when such an allocation
6703 failed have been fixed.
6704

6706-------
6707
Hirokazu Yamamoto838c79f2008-08-20 13:14:07 +00006708- Issue #3612: Added some missing basic types in ctypes.wintypes.
6709
Benjamin Petersone977ad42008-08-20 01:42:01 +00006710- The methods ``is_in_tuple()``, ``is_vararg()``, and ``is_keywordarg()`` of
6711 symtable.Symbol have been deprecated for removal in 3.0 and the next release.
6712
Amaury Forgeot d'Arc351ffb82008-08-18 19:23:47 +00006713- Issue #2234: distutils failed for some versions of the cygwin compiler. The
6714 version reported by these tools does not necessarily follow the python
6715 version numbering scheme, so the module is less strict when parsing it.
6716
Nick Coghlanf70385a2008-08-18 12:42:46 +00006717- Issue #2235: Added Py3k warnings for types which will become unhashable
6718 under the stricter __hash__ inheritance rules in 3.0. Several types
6719 which did not meet the rules for hash invariants and were already
6720 unhashable in 3.0 have now been explicitly flagged as unhashable in
6721 2.6 as well (collections.Mapping, collections.Set, unittest.TestSuite,
6722 xml.dom.minidom.NamedNodeMap, numbers.Number, UserList.UserList)
6723
Brett Cannon88f801d2008-08-18 00:46:22 +00006724- Update __all__ for cookielib, csv, os, urllib2, and weakref to include things

6726
Brett Cannon7b96f072008-08-18 00:41:11 +00006727- Remove an unneeded import of abc.ABCMeta from 'inspect'.
6728
Brett Cannon46225e72008-08-18 00:36:52 +00006729- Remove unneeded imports of 'sys' and 'warnings' from 'io'.

Brett Cannon25c9d6a2008-08-17 22:10:11 +00006731- Remove unneeded imports of 'warnings' from shelve, filecmp, and dummy_thread.
6732
Hirokazu Yamamoto41a81eb2008-08-17 13:10:46 +00006733- Issue #3575: Incremental decoder's decode function now takes bytearray
6734 by using 's*' instead of 't#'.
6735
Mark Dickinson3e4caeb2009-02-21 20:27:01 +00006736- Issue #2222: Fixed reference leak when occurred os.rename()
Hirokazu Yamamoto7f30a682008-08-17 09:46:56 +00006737 fails unicode conversion on 2nd parameter. (windows only)
6738
Georg Brandl222e2082010-08-01 22:27:39 +00006739- Issue #2464: urllib2 now supports a malformation in the URL received
Facundo Batista94f243a2008-08-17 03:38:39 +00006740 in a redirect.
6741
Brett Cannonabe423e2008-08-16 21:47:07 +00006742- Silence the DeprecationWarning raised when importing mimetools in
Brett Cannon721b1452008-08-16 22:00:27 +00006743 BaseHTTPServer, cgi (and rfc822), httplib.
Brett Cannonabe423e2008-08-16 21:47:07 +00006744
Facundo Batistaeb90b782008-08-16 14:44:07 +00006745- Issue #2776: fixed small issue when handling an URL with double slash
6746 after a 302 response in the case of not going through a proxy.
6747
Antoine Pitroub90a8be2008-08-15 21:03:21 +00006748- Issue #2676: in the email package, content-type parsing was hanging on
6749 pathological input because of quadratic or exponential behaviour of a
6750 regular expression.
6751
Antoine Pitrou11ec65d2008-08-14 21:04:30 +00006752- Issue #3476: binary buffered reading through the new "io" library is now
6753 thread-safe.
6754
Brett Cannonbf3157b2008-08-14 05:00:03 +00006755- Silence the DeprecationWarning of rfc822 when it is imported by mimetools
6756 since mimetools itself is deprecated. Because modules are cached, all
6757 subsequent imports of rfc822 will not raise a visible DeprecationWarning.
6758
Antoine Pitrou9fcd4b32008-08-11 17:21:36 +00006759- Issue #3134: shutil referenced undefined WindowsError symbol.
6760
Robert Schuppenies14646332008-08-10 11:01:53 +00006761- Issue #1342811: Fix leak in Tkinter.Menu.delete. Commands associated to
6762 menu entries were not deleted.
6763
Brett Cannon83e81842008-08-09 23:30:55 +00006764- Copied the implementation of reduce() to _functools.reduce() to have a
6765 version that did not raise a DeprecationWarning under -3.
6766
Antoine Pitrou76b8bee2008-08-09 17:27:23 +00006767- Issue #3205: When iterating over a BZ2File fails allocating memory, raise
6768 a MemoryError rather than silently stop the iteration.
6769
Guido van Rossum59ce9012008-08-09 14:55:34 +00006770- Issue #3487: sre "bytecode" validator. Passing invalid "re-bytecode"
6771 to _sre.compile() will now be rejected. This should not affect anybody
6772 since the re.compile() function never generates invalid re-bytecode.
6773
Skip Montanaroa032bf42008-08-08 22:52:51 +00006774- Issue #3436: Make csv.DictReader's fieldnames attribute a property so that
6775 upon first access it can be automatically initialized from the csv file if
6776 it wasn't initialized during instantiation.
6777
Brett Cannon3aa2a492008-08-06 22:28:09 +00006778- Issue #2338: Create imp.reload() to help with transitioning to Python 3.0 as
6779 the reload() built-in has been removed.
6780
Brett Cannon7e30b672008-08-04 21:52:25 +00006781- Changed code in the following modules/packages to remove warnings raised
Brett Cannonc1b76e42008-08-09 23:06:16 +00006782 while running under the ``-3`` flag: aifc, asynchat, asyncore, bdb, bsddb,

Antoine Pitroude781a42008-08-09 12:43:23 +00006793 asking for a specific length. This problem only affected files opened
6794 using the new "io" module, not the built-in open() function.
Benjamin Peterson01a24322008-07-28 23:35:27 +00006795

6803
Georg Brandlf9efabb2008-07-23 15:16:45 +00006804- Deprecate the "ast" parser function aliases.

6818
Antoine Pitrou5fdfa3e2008-07-25 19:42:26 +00006819- Issue #3394: zipfile.writestr sets external attributes when passed a
6820 file name rather than a ZipInfo instance, so files are extracted with
6821 mode 0600 rather than 000 under Unix.
6822
Gregory P. Smitha36f8fe2008-08-04 00:13:29 +00006823- Issue #1857: subprocess.Popen.poll gained an additional _deadstate keyword
6824 argument in python 2.5, this broke code that subclassed Popen to include its
6825 own poll method. Fixed my moving _deadstate to an _internal_poll method.

Nick Coghlan2a0c2b12008-08-04 12:47:17 +00006838- Issue #643841: The language reference now provides more detailed
6839 coverage of the lookup process for special methods. The disclaimers
6840 regarding lack of coverage of new-style classes have also been

Raymond Hettingere3ae6552008-06-20 04:18:15 +00006849Core and Builtins
6850-----------------
6851
Georg Brandl3e483f62008-07-16 22:57:41 +00006852- Issue #3156: Fix inconsistent behavior of the bytearray type: all
6853 its methods now allow for items objects that can be converted to
6854 an integer using operator.index().
6855
Mark Dickinson64b7e502008-07-16 09:40:03 +00006856- Issue #3360: Fix incorrect parsing of '020000000000.0', which
6857 produced a ValueError instead of giving the correct float.
6858
Eric Smitha5fa5a22008-07-16 00:11:49 +00006859- Issue #3083: Add alternate (#) formatting for bin, oct, hex output
6860 for str.format(). This adds the prefix 0b, 0o, or 0x, respectively.
6861
Mark Dickinson7103aa42008-07-15 19:08:33 +00006862- Issue #3008: the float type has a new instance method 'float.hex'
6863 and a new class method 'float.fromhex' to convert floating-point
6864 numbers to and from hexadecimal strings, respectively.
6865
Nick Coghlan6d6bd442008-07-15 15:40:22 +00006866- Issue #2235: __hash__ is once again inherited by default. To allow
6867 collections.Hashable to remain meaningful in the presence of the
6868 default hash implementation (object.__hash__), it is now possible
6869 to explicit block inheritance of hash by setting __hash__=None at
6870 the Python level, or tp_hash=PyObject_HashNotImplemented at the C
6871 level.
6872
Nick Coghlanb028f502008-07-13 14:52:36 +00006873- Issue #3221: Issue a RuntimeWarning instead of raising SystemError if
6874 the parent module cannot be found while performing an absolute import.
6875 This means that an incorrectly defined __package__ attribute will
6876 now only prevent relative imports in that module rather than causing
6877 all imports from that module to fail.
6878
Nick Coghlan14ff9942008-07-08 14:21:42 +00006879- Issue #2517: Allow unicode messages in Exceptions again by correctly
6880 bypassing the instance dictionary when looking up __unicode__ on
6881 new-style classes.

6884 set to a custom object whose write() method happens to install
6885 another file in sys.stdout.

6888 threading.local: the first member set by a thread could be saved in
6889 another thread's dictionary.
6890
Mark Dickinson1ec2fcd2008-06-20 14:53:43 +00006891- Issue #3004: Minor change to slice.indices(): the start and stop
6892 arguments are now treated identically, making the behaviour easier
6893 to describe and understand. For example, slice(None, -10,
6894 1).indices(9) now returns (0, 0, 1) instead of (0, -1, 1), and
6895 slice(None, 10, -1).indices(10) returns (9, 9, -1) instead of (9,
6896 10, -1).
6897
Georg Brandl278fc502008-07-19 12:46:12 +00006898- Issue #3219: Calling a function with repeated keyword arguments,
6899 f(a=2, a=23), would not cause a syntax error. This was a regression
6900 from 2.4 caused by the switch to the new compiler.

6910 api functions without holding the GIL, which could lead to a fatal
6911 error when they failed.
6912
Martin v. Löwisaabf4042008-08-02 07:20:25 +00006913- Issue #799428: Fix Tkinter.Misc._nametowidget to unwrap Tcl command objects.

Amaury Forgeot d'Arc0f7cddc2008-07-06 21:34:39 +00006938- Issue #839496: SimpleHTTPServer used to open text files in text mode. This is
6939 both unnecessary (HTTP allows text content to be sent in several forms) and
Andrew M. Kuchlingcc3f2b12008-07-10 14:43:31 +00006940 wrong because the actual transmitted size could differ from the
Amaury Forgeot d'Arc0f7cddc2008-07-06 21:34:39 +00006941 content-length. The problem had been corrected in the 2.4 branch, but never
6942 merged into trunk.

Nick Coghlanc060b0e2008-07-02 13:09:19 +00006957- Issue #3190: Pydoc now hides the automatic module attribute __package__ (the
6958 handling is now the same as that of other special attributes like __name__).

7414 using the 'warning's machinery in such places as the parser where
7415 use of pure Python code is not possible. Both the ``showarning()``
7416 and ``formatwarning()`` gain an optional 'line' argument which is
7417 not called by default for backwards-compatibility reasons. Setting
7418 ``warnings.showwarning()`` to an implementation that lacks support
7419 for the ``line`` argument will raise a DeprecationWarning.

Georg Brandl3ee81df2008-05-17 18:14:43 +00007482- Issue #2550: The approach used by client/server code for obtaining
7483 ports to listen on in network-oriented tests has been refined in an
7484 effort to facilitate running multiple instances of the entire
7485 regression test suite in parallel without issue.
7486 test_support.bind_port() has been fixed such that it will always
7487 return a unique port -- which wasn't always the case with the
7488 previous implementation, especially if socket options had been set
7489 that affected address reuse (i.e. SO_REUSEADDR, SO_REUSEPORT). The
7490 new implementation of bind_port() will actually raise an exception
7491 if it is passed an AF_INET/SOCK_STREAM socket with either the
7492 SO_REUSEADDR or SO_REUSEPORT socket option set. Furthermore, if
7493 available, bind_port() will set the SO_EXCLUSIVEADDRUSE option on
7494 the socket it's been passed. This currently only applies to
7495 Windows. This option prevents any other sockets from binding to the
7496 host/port we've bound to, thus removing the possibility of the
7497 'non-deterministic' behaviour, as Microsoft puts it, that occurs
7498 when a second SOCK_STREAM socket binds and accepts to a host/port
7499 that's already been bound by another socket. The optional preferred
7500 port parameter to bind_port() has been removed. Under no
7501 circumstances should tests be hard coding ports!
7502
7503 test_support.find_unused_port() has also been introduced, which will
7504 pass a temporary socket object to bind_port() in order to obtain an
7505 unused port. The temporary socket object is then closed and
7506 deleted, and the port is returned. This method should only be used
7507 for obtaining an unused port in order to pass to an external program
7508 (i.e. the -accept [port] argument to openssl's s_server mode) or as
7509 a parameter to a server-oriented class that doesn't give you direct
7510 access to the underlying socket used.
7511
7512 Finally, test_support.HOST has been introduced, which should be used
7513 for the host argument of any relevant socket calls (i.e. bind and
7514 connect).
Trent Nelsone41b0062008-04-08 23:47:30 +00007515
7516 The following tests were updated to following the new conventions:
Georg Brandl3ee81df2008-05-17 18:14:43 +00007517 test_socket, test_smtplib, test_asyncore, test_ssl, test_httplib,
Trent Nelsone41b0062008-04-08 23:47:30 +00007518 test_poplib, test_ftplib, test_telnetlib, test_socketserver,
7519 test_asynchat and test_socket_ssl.
7520
Georg Brandl3ee81df2008-05-17 18:14:43 +00007521 It is now possible for multiple instances of the regression test
7522 suite to run in parallel without issue.

Eric Smitha73fbe72008-02-23 03:09:44 +00007801- Added the future_builtins module, which contains hex() and oct().
7802 These are the PEP 3127 version of these functions, designed to be
7803 compatible with the hex() and oct() builtins from Python 3.0. They
7804 differ slightly in their output formats from the existing, unchanged
7805 Python 2.6 builtins. The expected usage of the future_builtins
7806 module is:
7807 from future_builtins import hex, oct
7808
Eric Smith7ef40bf2008-02-20 23:34:22 +00007809- Issue #1600: Modifed PyOS_ascii_formatd to use at most 2 digit
7810 exponents for exponents with absolute value < 100. Follows C99
7811 standard. This is a change on Windows, which would use 3 digits.
7812 Also, added 'n' to the formats that PyOS_ascii_formatd understands,
7813 so that any alterations it does to the resulting string will be
7814 available in stringlib/formatter.h (for float.__format__).
7815
Eric Smith5a3c1352008-02-19 13:21:56 +00007816- Implemented PEP 3101, Advanced String Formatting. This adds a new
7817 builtin format(); a format() method for str and unicode; a
7818 __format__() method to object, str, unicode, int, long, float, and
7819 datetime; the class string.Formatter; and the C API
7820 PyObject_Format().
7821
Georg Brandl3ee81df2008-05-17 18:14:43 +00007822- Fixed several potential crashes, all caused by specially crafted
7823 __del__ methods exploiting objects in temporarily inconsistent
7824 state.
Amaury Forgeot d'Arc632fad32008-02-16 20:55:24 +00007825
Vinay Sajipb7edfc42008-04-02 21:10:23 +00007826- Issue #2115: Important speedup in setting __slot__ attributes. Also
Georg Brandl3ee81df2008-05-17 18:14:43 +00007827 prevent a possible crash: an Abstract Base Class would try to access
7828 a slot on a registered virtual subclass.

7834 in order to allow pymalloc to free more arenas. Python may give back
7835 memory to the OS earlier.
Christian Heimes3b718a72008-02-14 12:47:33 +00007836
Georg Brandl3ee81df2008-05-17 18:14:43 +00007837- Issue #2045: Fix an infinite recursion triggered when printing a
7838 subclass of collections.defaultdict, if its default_factory is set
7839 to a bound method.
Amaury Forgeot d'Arcb01aa432008-02-08 00:56:02 +00007840
Christian Heimesf75dbef2008-02-08 00:11:31 +00007841- Fixed a minor memory leak in dictobject.c. The content of the free
7842 list was not freed on interpreter shutdown.
7843
Georg Brandl21e99f42010-03-07 15:23:59 +00007844- Limit free list of method and built-in function objects to 256

7848 functions ``PyInt_CompactFreeList`` and ``PyFloat_CompactFreeList``
Christian Heimes422051a2008-02-04 18:00:12 +00007849 to compact the internal free lists of pre-allocted ints and floats.
7850
Georg Brandl3ee81df2008-05-17 18:14:43 +00007851- Issue #1983: Fixed return type of fork(), fork1() and forkpty()
7852 calls. Python expected the return type int but the fork familie
7853 returns pi_t.
Christian Heimes951cc0f2008-01-31 23:08:23 +00007854

Georg Brandl3ee81df2008-05-17 18:14:43 +00007867- Patch #1473257: generator objects gain a gi_code attribute. This is
7868 the same object as the func_code attribute of the function that
7869 produced the generator.
Georg Brandl0cdf9a32008-01-26 14:14:20 +00007870
Georg Brandl3ee81df2008-05-17 18:14:43 +00007871- Issue #1920: "while 0" statements were completely removed by the
7872 compiler, even in the presence of an "else" clause, which is
7873 supposed to be run when the condition is false. Now the compiler
7874 correctly emits bytecode for the "else" suite.
Amaury Forgeot d'Arc31eaafe2008-01-24 22:59:25 +00007875

Georg Brandl3ee81df2008-05-17 18:14:43 +00007902- Objects/structseq.c: Implemented new structseq representation. The
7903 patch makes structseqs (e.g. the return value of os.stat) more
7904 readable.
Christian Heimes9c201962008-01-14 03:33:52 +00007905
Georg Brandl3ee81df2008-05-17 18:14:43 +00007906- Patch #1700288: added a type attribute cache that caches method
7907 accesses, resulting in speedups in heavily object-oriented code.
Amaury Forgeot d'Arce4c270c2008-01-14 00:29:41 +00007908
Neal Norwitz3fc15b82008-01-10 05:42:58 +00007909- Bug #1776: __import__() no longer accepts filenames on any platform.
7910 The first parameter to __import__() must be a valid module name.

Georg Brandlaed6c662008-01-07 17:25:53 +00007912- Patch #1668: renamed THREADDEBUG envvar to PYTHONTHREADDEBUG.
7913
Georg Brandl3ee81df2008-05-17 18:14:43 +00007914- Patch #602345: Add -B command line option, PYTHONDONTWRITEBYTECODE
7915 envvar and sys.dont_write_bytecode attribute. All these can be set
7916 to forbid Python to attempt to write compiled bytecode files.
Georg Brandl2da0fce2008-01-07 17:09:35 +00007917
Georg Brandl3ee81df2008-05-17 18:14:43 +00007918- Improve some exception messages when Windows fails to load an
7919 extension module. Now we get for example '%1 is not a valid Win32
7920 application' instead of 'error code 193'.
Amaury Forgeot d'Arce0b76952008-01-04 02:04:15 +00007921

Christian Heimes0a8143f2007-12-18 23:22:54 +00007927- Issue #1635: Platform independent creation and representation of NaN
Georg Brandl3ee81df2008-05-17 18:14:43 +00007928 and INF. float("nan"), float("inf") and float("-inf") now work on
7929 every platform with IEEE 754 semantics.

Georg Brandl3ee81df2008-05-17 18:14:43 +00007931- Compiler now generates simpler and faster code for dictionary
7932 literals. The oparg for BUILD_MAP now indicates an estimated
7933 dictionary size. There is a new opcode, STORE_MAP, for adding
7934 entries to the dictionary.

Georg Brandl3ee81df2008-05-17 18:14:43 +00007963- Patch #1739468: Directories and zipfiles containing a __main__.py
7964 file can now be directly executed by passing their name to the
7965 interpreter. The directory/zipfile is automatically inserted as the
7966 first entry in sys.path.

Georg Brandl3ee81df2008-05-17 18:14:43 +00007968- Issue #1265: Fix a problem with sys.settrace, if the tracing
7969 function uses a generator expression when at the same time the
7970 executed code is closing a paused generator.
Amaury Forgeot d'Arc0d75f092007-11-13 21:54:28 +00007971
Raymond Hettinger1760c8a2007-11-08 02:52:43 +00007972- sets and frozensets now have an isdisjoint() method.
7973

7977
Georg Brandl21e99f42010-03-07 15:23:59 +00007978- The enumerate() built-in function is no longer bounded to sequences
Georg Brandl3ee81df2008-05-17 18:14:43 +00007979 smaller than LONG_MAX. Formerly, it raised an OverflowError. Now,
7980 automatically shifts from ints to longs.
Raymond Hettinger8f669372007-10-03 21:18:11 +00007981
Georg Brandl3ee81df2008-05-17 18:14:43 +00007982- Issue #1686386: Tuple's tp_repr did not take into account the
7983 possibility of having a self-referential tuple, which is possible
7984 from C code. Nor did object's tp_str consider that a type's tp_str
7985 could do something that could lead to an inifinite recursion.
7986 Py_ReprEnter() and Py_EnterRecursiveCall(), respectively, fixed the
7987 issues.
Brett Cannon0b14f242007-09-30 19:45:10 +00007988
Georg Brandl3ee81df2008-05-17 18:14:43 +00007989- Issue #1164: It was possible to trigger deadlock when using the
7990 'print' statement to write to a file since the GIL was not released
7991 as needed. Now PyObject_Print() does the right thing along with
7992 various tp_print implementations of the built-in types and those in
7993 the collections module.
Brett Cannon01531592007-09-17 03:28:34 +00007994
Georg Brandl3ee81df2008-05-17 18:14:43 +00007995- Issue #1147: Exceptions were directly allowing string exceptions in
7996 their throw() method even though string exceptions no longer
7997 allowed.

Brett Cannona0c05512007-09-10 21:38:27 +00008001
Brett Cannon1e534b52007-09-07 04:18:30 +00008002- Issue #1202533: Fix infinite recursion calls triggered by calls to
Georg Brandl3ee81df2008-05-17 18:14:43 +00008003 PyObject_Call() never calling back out to Python code to trigger
8004 recursion depth updates/checks. Required the creation of a static
8005 RuntimeError instance in case normalizing an exception put the
8006 recursion check value past its limit. Fixes crashers
8007 infinite_rec_(1|2|4|5).py.
Brett Cannon1e534b52007-09-07 04:18:30 +00008008
Georg Brandl3ee81df2008-05-17 18:14:43 +00008009- Patch #1031213: Decode source line in SyntaxErrors back to its

Neal Norwitz0ac60192007-05-27 04:08:54 +00008022- Add new attribute names for function objects. All the func_* become
Georg Brandl3ee81df2008-05-17 18:14:43 +00008023 __*__ attributes. (Some already existed, e.g., __doc__ and
8024 __name__.)
Neal Norwitz0ac60192007-05-27 04:08:54 +00008025
Neal Norwitz8b2bfbc2007-05-23 06:35:32 +00008026- Add -3 option to the interpreter to warn about features that are
8027 deprecated and will be changed/removed in Python 3.0.
8028
Georg Brandl2134e752007-05-21 20:34:16 +00008029- Patch #1686487: you can now pass any mapping after '**' in function
8030 calls.
8031
Collin Winter62903052007-05-18 23:11:24 +00008032- except clauses may now be spelled either "except E, target:" or
Georg Brandl3ee81df2008-05-17 18:14:43 +00008033 "except E as target:". This is to provide forwards compatibility
8034 with Python 3.0.
Collin Winter62903052007-05-18 23:11:24 +00008035
Brett Cannon229cee22007-05-05 01:34:02 +00008036- Deprecate BaseException.message as per PEP 352.

Vinay Sajip8549ce32007-05-06 17:53:37 +00008041- When __slots__ are set to a unicode string, make it work the same as
Neal Norwitzcbd9ee62007-04-14 05:25:50 +00008042 setting a plain string, ie don't expand to single letter identifiers.
8043
Raymond Hettinger13936692007-04-11 18:40:58 +00008044- Request #1191699: Slices can now be pickled.
8045
Raymond Hettinger4db5fe92007-04-12 04:10:00 +00008046- Request #1193128: str.translate() now allows a None argument for
8047 translations that only remove characters without re-mapping the
8048 remaining characters.
8049
Georg Brandl5cb76c12007-03-21 09:00:39 +00008050- Patch #1682205: a TypeError while unpacking an iterable is no longer
8051 masked by a generic one with the message "unpack non-sequence".
8052
Neal Norwitzaa754b72007-03-21 06:39:48 +00008053- Remove unused file Python/fmod.c.
8054
Guido van Rossum143b5642007-03-23 04:58:42 +00008055- Bug #1683368: The object.__init__() and object.__new__() methods are
8056 now stricter in rejecting excess arguments. The only time when
8057 either allows excess arguments is when it is not overridden and the
8058 other one is. For backwards compatibility, when both are
8059 overridden, it is a deprecation warning (for now; maybe a Py3k
Guido van Rossum234b1ff2007-03-23 19:39:01 +00008060 warning later). Also, type.__init__() insists on the same signature
8061 as supported by type.__new__().
Guido van Rossum143b5642007-03-23 04:58:42 +00008062
Georg Brandl3ee81df2008-05-17 18:14:43 +00008063- Patch #1675423: PyComplex_AsCComplex() now tries to convert an
8064 object to complex using its __complex__() method before falling back
8065 to the __float__() method. Therefore, the functions in the cmath
8066 module now can operate on objects that define a __complex__()
8067 method.
Georg Brandl2b869942007-03-17 16:08:45 +00008068
Georg Brandl3ee81df2008-05-17 18:14:43 +00008069- Patch #1623563: allow __class__ assignment for classes with
8070 __slots__. The old and the new class are still required to have the
8071 same slot names.
Žiga Seilnacht6f2d09c2007-03-16 11:59:38 +00008072

8084
Georg Brandl7b9c5552007-03-12 14:30:05 +00008085- Bug #1678647: write a newline after printing an exception in any
8086 case, even when converting the value to a string failed.
8087
Georg Brandl871f1bc2007-03-12 13:17:36 +00008088- The dir() function has been extended to call the __dir__() method on
Georg Brandl3ee81df2008-05-17 18:14:43 +00008089 its argument, if it exists. If not, it will work like before. This
8090 allows customizing the output of dir() in the presence of a
8091 __getattr__().

8100 parthensized forms. This means complex(repr(x)) now works instead of
8101 raising a ValueError.
Collin Wintere38051d2007-03-09 20:33:07 +00008102
Georg Brandlaa2321b2007-03-07 00:40:28 +00008103- Patch #703779: unset __file__ in __main__ after running a file. This
Georg Brandl3ee81df2008-05-17 18:14:43 +00008104 makes the filenames the warning module prints much more sensible
8105 when a PYTHONSTARTUP file is used.
Georg Brandlaa2321b2007-03-07 00:40:28 +00008106

Georg Brandl0fca97a2007-03-05 22:28:08 +00008118- Patch #1674228: when assigning a slice (old-style), check for the
8119 sq_ass_slice instead of the sq_slice slot.
8120
Georg Brandl3ee81df2008-05-17 18:14:43 +00008121- When printing an unraisable error, don't print exceptions. before
8122 the name. This duplicates the behavior whening normally printing
8123 exceptions.

Facundo Batistab6a5c9d2007-03-29 18:22:35 +00008625- Added a timeout parameter to the constructor of other protocols
8626 (telnetlib, ftplib, smtplib and poplib). This is second part of the
8627 work started with create_connection() and timeout in httplib, and
8628 closes patch #723312.
8629
Vinay Sajip8549ce32007-05-06 17:53:37 +00008630- Patch #1676823: Added create_connection() to socket.py, which may be
8631 called with a timeout, and use it from httplib (whose HTTPConnection
Facundo Batista70f996b2007-05-21 17:32:32 +00008632 and HTTPSConnection now accept an optional timeout).
Facundo Batista07c78be2007-03-23 18:54:07 +00008633

8646 GNOME or KDE browser, depending on whether there is a session of one
8647 of those present. Also, it tries the Windows default browser before

8654
Georg Brandlf66b6032007-03-14 08:27:52 +00008655- Bug #767111: fix long-standing bug in urllib which caused an
Georg Brandl3ee81df2008-05-17 18:14:43 +00008656 AttributeError instead of an IOError when the server's response
8657 didn't contain a valid HTTP status line.
Georg Brandlf66b6032007-03-14 08:27:52 +00008658
Georg Brandl3ee81df2008-05-17 18:14:43 +00008659- Patch #957650: "%var%" environment variable references are now
8660 properly expanded in ntpath.expandvars(), also "~user" home

Georg Brandl3ee81df2008-05-17 18:14:43 +00008663- Patch #1429539: pdb now correctly initializes the __main__ module
8664 for the debugged script, which means that imports from __main__ work
Georg Brandlb6ae6aa2007-03-13 21:58:44 +00008665 correctly now.
8666
Georg Brandlbad6f192007-03-13 21:32:56 +00008667- The nonobvious commands.getstatus() function is now deprecated.

8673
Georg Brandl3ee81df2008-05-17 18:14:43 +00008674- Patch #1530482: add pydoc.render_doc() which returns the
8675 documentation for a thing instead of paging it to stdout, which

8684 parameter which can be set to False to prevent the default
8685 delete-on-close behavior.
Georg Brandl35ef9c12007-03-13 18:31:49 +00008686
Georg Brandl9e6b4702007-03-13 18:15:41 +00008687- Patch #1581073: add a flag to textwrap that prevents the dropping of
8688 whitespace while wrapping.
8689
Georg Brandl92a6bae2007-03-13 17:43:32 +00008690- Patch #1603688: ConfigParser.SafeConfigParser now checks values that
Georg Brandl3ee81df2008-05-17 18:14:43 +00008691 are set for invalid interpolation sequences that would lead to
8692 errors on reading back those values.
Georg Brandl92a6bae2007-03-13 17:43:32 +00008693

Georg Brandl94fe3f52007-03-13 09:32:11 +00008707- Patch #1635454: the csv.DictWriter class now includes the offending
Georg Brandl3ee81df2008-05-17 18:14:43 +00008708 field names in its exception message if you try to write a record
8709 with a dictionary containing fields not in the CSV field names list.

8735 returned string up to the first NUL character.
8736

8746
Georg Brandl3ee81df2008-05-17 18:14:43 +00008747- unittest now verifies more of its assumptions. In particular,
8748 TestCase and TestSuite subclasses (not instances) are no longer
8749 accepted in TestSuite.addTest(). This should cause no
8750 incompatibility since it never made sense with ordinary subclasses
8751 -- the failure just occurred later, with a more cumbersome
8752 exception.
Georg Brandl9caadf82007-03-08 18:37:31 +00008753

8762
Georg Brandl3ee81df2008-05-17 18:14:43 +00008763- Patch #1673619: setup.py identifies extension modules it doesn't

9107 the behavior into line with that for list.__init__().
Raymond Hettingeradf9ffd2007-12-13 00:08:37 +00009108

Georg Brandl3ee81df2008-05-17 18:14:43 +00009116- Marshal.dumps() now expects exact type matches for int, long, float,
9117 complex, tuple, list, dict, set, and frozenset. Formerly, it would
9118 silently miscode subclasses of those types. Now, it raises a
9119 ValueError instead.

Gregory P. Smithec10a4a2007-11-05 02:32:26 +00009134- pybsddb.sf.net Bug #477182: Load the database flags at database open
Georg Brandl3ee81df2008-05-17 18:14:43 +00009135 time so that opening a database previously created with the DB_DUP
9136 or DB_DUPSORT flag set will keep the proper behavior on subsequent
9137 opens. Specifically: dictionary assignment to a DB object will
9138 replace all values for a given key when the database allows
9139 duplicate values. DB users should use DB.put(k, v) when they want
9140 to store duplicates; not DB[k] = v.

9147 characters with ASCII value less than 32. Also, it correctly quotes
9148 dots only if they occur on a single line, as opposed to the previous
9149 behavior of quoting dots if they are the second character of any
9150 line.
