125
Ned Deily87e82bb2011-06-28 19:52:59 -0700126- Issue #9516: On Mac OS X, change Distutils to no longer globally attempt to
127 check or set the MACOSX_DEPLOYMENT_TARGET environment variable for the
128 interpreter process. This could cause failures in non-Distutils subprocesses
129 and was unreliable since tests or user programs could modify the interpreter
130 environment after Distutils set it. Instead, have Distutils set the the
131 deployment target only in the environment of each build subprocess. It is
132 still possible to globally override the default by setting
133 MACOSX_DEPLOYMENT_TARGET before launching the interpreter; its value must be
134 greater or equal to the default value, the value with which the interpreter
135 was built.

141 Kitada.

144 times without error, and _ProxyFile now closes the wrapped file.
145
Victor Stinnerc74a6ba2011-06-17 14:06:27 +0200146- Issue #12133: AbstractHTTPHandler.do_open() of urllib.request closes the HTTP
147 connection if its getresponse() method fails with a socket error. Patch
148 written by Ezio Melotti.
149
Benjamin Peterson0eb4ac42011-06-11 15:53:11 -0500150- Issue #9284: Allow inspect.findsource() to find the source of doctest
151 functions.
152

162
Barry Warsawc5643282011-07-19 17:06:30 -0400163- sys.setcheckinterval() now updates the current ticker count as well as
164 updating the check interval, so if the user decreases the check interval,
165 the ticker doesn't have to wind down to zero from the old starting point
166 before the new interval takes effect. And if the user increases the
167 interval, it makes sure the new limit takes effect right away rather have an
168 early task switch before recognizing the new interval.
Raymond Hettinger19b851d2011-06-01 18:21:42 -0700169
Victor Stinner776e69b2011-06-01 01:03:00 +0200170- Issue #12085: Fix an attribute error in subprocess.Popen destructor if the

1015 by Andrew Bennetts.

1024
Raymond Hettinger20397532010-09-12 02:11:45 +00001025- Issue #9825: removed __del__ from the definition of collections.OrderedDict.
1026 This prevents user-created self-referencing ordered dictionaries from
1027 becoming permanently uncollectable GC garbage. The downside is that
1028 removing __del__ means that the internal doubly-linked list has to wait for
1029 GC collection rather than freeing memory immediately when the refcnt drops
1030 to zero.
1031
Raymond Hettingerffd2a422010-09-10 10:47:22 +00001032- Issue #9816: random.Random.jumpahead(n) did not produce a sufficiently

1035
Antoine Pitrouc818ed42010-09-07 21:40:25 +00001036- Issue #9792: In case of connection failure, socket.create_connection()
1037 would swallow the exception and raise a new one, making it impossible
1038 to fetch the original errno, or to filter timeout errors. Now the
1039 original error is re-raised.
1040
Antoine Pitrouf4f61712010-09-07 16:34:47 +00001041- Issue #9758: When fcntl.ioctl() was called with mutable_flag set to True,
1042 and the passed buffer was exactly 1024 bytes long, the buffer wouldn't
1043 be updated back after the system call. Original patch by Brian Brazil.

1050
Daniel Stutzbach66c981b2010-08-31 20:29:39 +00001051- Issue #808164: Fixed socket.close to avoid references to globals, to

1059 falling into recursion.
1060
R. David Murray7c4bf552010-08-25 01:45:57 +00001061- Issue #1194222: email.utils.parsedate now returns RFC2822 compliant four
1062 character years even if the message contains RFC822 two character years.
1063
Daniel Stutzbach91287322010-08-24 21:09:30 +00001064- Issue #8750: Fixed MutableSet's methods to correctly handle

1076 module now correctly return a set. (Patch by Eli Bendersky.)
1077
Antoine Pitrou3ebaed62010-08-21 19:17:25 +00001078- Issue #9617: Signals received during a low-level write operation aren't
1079 ignored by the buffered IO layer anymore.
1080
Benjamin Peterson52c36052010-08-21 03:03:22 +00001081- Issue #2521: Use weakrefs on for caching in the abc module, so that classes
1082 are not held onto after they are deleted elsewhere.
1083
Raymond Hettingera54b2da2010-08-17 19:03:06 +00001084- Issue #9626: the view methods for collections.OrderedDict() were returning
1085 the unordered versions inherited from dict. Those methods are now
1086 overridden to provide ordered views.
1087
Éric Araujo0389ae62010-08-14 03:07:46 +00001088- Issue #8688: MANIFEST files created by distutils now include a magic
1089 comment indicating they are generated. Manually maintained MANIFESTs
1090 without this marker will not be overwritten or removed.
1091
Antoine Pitroue1436d12010-08-12 15:25:51 +00001092- Issue #7467: when reading a file from a ZIP archive, its CRC is checked
1093 and a BadZipfile error is raised if it doesn't match (as used to be the
1094 case in Python 2.5 and earlier).
1095
Antoine Pitroucb4f47c2010-08-11 13:40:17 +00001096- Issue #9550: a BufferedReader could issue an additional read when the
1097 original read request had been satisfied, which could block indefinitely
1098 when the underlying raw IO channel was e.g. a socket. Report and original
1099 patch by Jason V. Miller.
1100
Fred Drake0a1fa0e2010-08-10 13:09:54 +00001101- Issue #9551: Don't raise TypeError when setting the value to None for

1120 This is how it is supposed to work, wget and curl do the same. Previous
1121 behavior was wrong.

1129 the option character for the added 'h/help' option if prefix_chars
1130 does not contain a '-', instead of raising an error.
1131

Georg Brandlfee0f442010-05-22 21:26:21 +00001749- Issue #2302: Fix a race condition in SocketServer.BaseServer.shutdown, where
1750 the method could block indefinitely if called just before the event loop
1751 started running. This also fixes the occasional freezes witnessed in
1752 test_httpservers.

Antoine Pitroufc69af12010-04-24 20:04:58 +00001754- Issue #5103: SSL handshake would ignore the socket timeout and block
1755 indefinitely if the other end didn't respond.
1756
Georg Brandlfee0f442010-05-22 21:26:21 +00001757- The do_handshake() method of SSL objects now adjusts the blocking mode of the

1876
Benjamin Peterson3a1dfa22010-04-06 21:50:00 +00001877- Issue #8329: Don't return the same lists from select.select when no fds are
1878 changed.
1879
Georg Brandlfee0f442010-05-22 21:26:21 +00001880- Issue #8259: ``1L << (2**31)`` no longer produces an 'outrageous shift error'

Georg Brandlfee0f442010-05-22 21:26:21 +00001890- Issue #7994: Issue a PendingDeprecationWarning if object.__format__ is called
1891 with a non-empty format string. This is an effort to future-proof user
1892 code. If a derived class does not currently implement __format__ but later
1893 adds its own __format__, it would most likely break user code that had
Antoine Pitrou01a196a2011-01-02 20:05:11 +00001894 supplied a format string. This will be changed to a DeprecationWarning in
Georg Brandlfee0f442010-05-22 21:26:21 +00001895 Python 3.3 and it will be an error in Python 3.4.

Georg Brandlfee0f442010-05-22 21:26:21 +00001945- Issue #7279: Comparisons involving a Decimal signaling NaN now signal
1946 InvalidOperation instead of returning False. (Comparisons involving a quiet
1947 NaN are unchanged.) Also, Decimal quiet NaNs are now hashable; Decimal
1948 signaling NaNs remain unhashable.
Mark Dickinsone096e822010-04-02 10:17:07 +00001949
Georg Brandlfee0f442010-05-22 21:26:21 +00001950- Issue #2531: Comparison operations between floats and Decimal instances now
1951 return a result based on the numeric values of the operands; previously they
1952 returned an arbitrary result based on the relative ordering of id(float) and
1953 id(Decimal).

Georg Brandlfee0f442010-05-22 21:26:21 +00001967- Comparisons using one of <, <=, >, >= between a complex instance and a
1968 Fractions instance now raise TypeError instead of returning True/False. This
1969 makes Fraction <=> complex comparisons consistent with int <=> complex, float
1970 <=> complex, and complex <=> complex comparisons.

Georg Brandlba83f822010-03-14 09:50:54 +00002332- Issue #7561: Operations on empty bytearrays (such as ``int(bytearray())``)
2333 could crash in many places because of the ``PyByteArray_AS_STRING()`` macro
2334 returning NULL. The macro now returns a statically allocated empty string
2335 instead.

2345 strings,
2346 (2) a crash in dtoa.c that occurred in debug builds when parsing certain long
2347 numeric strings corresponding to subnormal values,
2348 (3) a memory leak for some values large enough to cause overflow, and
2349 (4) a number of flaws that could lead to incorrectly rounded results.

Antoine Pitroud840e512010-02-04 20:20:18 +00002380- Issue #4772: Raise a ValueError when an unknown Bluetooth protocol is
Georg Brandlba83f822010-03-14 09:50:54 +00002381 specified, rather than fall through to AF_PACKET (in the ``socket`` module).
Antoine Pitroud840e512010-02-04 20:20:18 +00002382 Also, raise ValueError rather than TypeError when an unknown TIPC address
2383 type is specified. Patch by Brian Curtin.

Antoine Pitrouf3fa0742010-01-31 22:26:04 +00002387- Issue #6939: Fix file I/O objects in the `io` module to keep the original
Georg Brandlba83f822010-03-14 09:50:54 +00002388 file position when calling `truncate()`. It would previously change the file
2389 position to the given argument, which goes against the tradition of
Antoine Pitrouf3fa0742010-01-31 22:26:04 +00002390 ftruncate() and other truncation APIs. Patch by Pascal Chambon.
2391

2393 class used to represent files stored inside an archive. The new
2394 implementation is significantly faster and can be wrapped in a
2395 ``io.BufferedReader`` object for more speedups. It also solves an issue
2396 where interleaved calls to ``read()`` and ``readline()`` give wrong results.

Georg Brandlba83f822010-03-14 09:50:54 +00002407- Issue #7748: Since unicode values are supported for some metadata options in
2408 Distutils, the DistributionMetadata get_* methods will now return an utf-8
2409 encoded string for them. This ensures that the upload and register commands
2410 send the correct values to PyPI without any error.

2486
Georg Brandlba83f822010-03-14 09:50:54 +00002487- The ``__complex__()`` method is now looked up on the class of instances to
2488 make it consistent with other special methods.
Benjamin Petersonecdae192010-01-04 00:43:01 +00002489
Antoine Pitrou5b7139a2010-01-02 21:12:58 +00002490- Issue #7462: Implement the stringlib fast search algorithm for the `rfind`,
2491 `rindex`, `rsplit` and `rpartition` methods. Patch by Florent Xicluna.
2492
Mark Dickinson1b34d252010-01-01 17:27:30 +00002493- Issue #5080: A number of functions and methods previously produced a
Georg Brandlba83f822010-03-14 09:50:54 +00002494 DeprecationWarning when passed a float argument where an integer was expected.
2495 These functions and methods now raise TypeError instead. The majority of the
2496 effects of this change are in the extension modules, but some core functions
2497 and methods are affected: notably the 'chr', 'range' and 'xrange' builtins,
2498 and many unicode/str methods.

2509 used to drop the time part of the result.
2510
Georg Brandlba83f822010-03-14 09:50:54 +00002511- Issue #1811: Improve accuracy and cross-platform consistency for true division
2512 of integers: the result of a/b is now correctly rounded for ints a and b (at
2513 least on IEEE 754 platforms), and in particular does not depend on the
2514 internal representation of a long.

Ronald Oussoren92919a62009-12-24 13:30:58 +00002521 executables on OSX.
2522
Georg Brandlba83f822010-03-14 09:50:54 +00002523 These executables now work properly with the arch(1) command: ``arch -ppc
2524 python`` will start a universal binary version of python in PPC mode (unlike
2525 previous releases).

Georg Brandlba83f822010-03-14 09:50:54 +00002548 renaming of `cPickle` to `pickle`. The warning was annoying since there's no

Georg Brandlba83f822010-03-14 09:50:54 +00002696 The conversions use a Python-adapted version of David Gay's well-known dtoa.c,
2697 providing correctly-rounded strtod and dtoa C functions. This code is
2698 supported on Windows, and on Unix-like platforms using gcc, icc or suncc as
2699 the C compiler. There may be a small number of platforms on which correct
2700 operation of this code cannot be guaranteed, so the code is not used: notably,
2701 this applies to platforms where the C double format is not IEEE 754 binary64,
2702 and to platforms on x86 hardware where the x87 FPU is set to 64-bit precision
2703 and Python's configure script is unable to determine how to change the FPU
2704 precision. On these platforms conversions use the platform strtod and dtoa,
2705 as before.

Georg Brandlba83f822010-03-14 09:50:54 +00002707- Issue #7117: Backport round implementation from Python 3.x. ``round()`` now
2708 uses the correctly-rounded string <-> float conversions described above (when
2709 available), and so produces correctly rounded results that will display nicely
2710 under the float repr. There are two related small changes: (1) round now
2711 accepts any class with an ``__index__()`` method for its second argument (but
2712 no longer accepts floats for the second argument), and (2) an excessively
2713 large second integer argument (e.g., ``round(1.234, 10**100)``) no longer
2714 raises an exception.

3093 this code path is really executed because I cannot move to such directory on

3120 PyUnicode_DecodeUTF8() once, remember the result and output it in a second

4284 integer format code ('bBhHiIlLqQ'). Packing an out-of-range integer now
4285 consistently raises struct.error.

Georg Brandlba83f822010-03-14 09:50:54 +00004291 - Packing a float now always gives a Deprecation Warning. Previously it
4292 only warned for 'I', 'L', '*B', '*H', '*I', '*L'.

Georg Brandlba83f822010-03-14 09:50:54 +00004294 - If x is not an int, long or float, then packing x will always result in
4295 struct.error. Previously an x with an __int__ method could be packed by
4296 'b', 'B', 'h', 'H', 'i', 'l', '*b', '*h' ,'*i', '*l', and an x with a
4297 __long__ method could be packed by 'q', 'Q', '*q', '*Q'; for x with
4298 neither __int__ nor __long__, TypeError used to be raised (with a
4299 confusing error message) for 'I', 'L', '*B', '*H', '*I', '*L', and
4300 struct.error in other cases.
Mark Dickinson463dc4b2009-07-05 10:01:24 +00004301
Georg Brandlba83f822010-03-14 09:50:54 +00004302 Note: as of Python 2.7 beta 1, the above is out of date. In 2.7 beta 1, any
4303 argument with an __int__ method can be packed, but use of this feature
4304 triggers a DeprecationWarning.

Amaury Forgeot d'Arc05e34492008-09-10 22:04:45 +00004497- Issue #3743: In a few places, PY_FORMAT_SIZE_T was incorrectly used with
4498 PyString_FromFormat or PyErr_Format to display size_t values. The macro
4499 PY_FORMAT_SIZE_T is designed to select the correct format for the OS
4500 ``printf`` function, whereas PyString_FromFormat has an independent
4501 implementation and uses "%zd" on all platforms for size_t values.
4502 This makes a difference on win64, where ``printf`` needs "%Id" to display

4509 object; previously an int would be returned for small values. the __long__
4510 method is allowed to return either an int or a long, but the behaviour of

4526 __instancecheck__ / __subclasscheck__ on the tuple rather than on each
4527 type object.

Nick Coghland2e09382008-09-11 12:11:06 +00004571- Issue #3781: Clean up the API for warnings.catch_warnings() by having it
Brett Cannon672237d2008-09-09 00:49:16 +00004572 return a list or None rather than a custom object.
4573
Benjamin Peterson6ac7d7c2008-09-06 19:28:11 +00004574- Issue #1638033: Cookie.Morsel gained the httponly attribute.

Brett Cannon1eaf0742008-09-02 01:25:16 +00004598 warnings.catch_warnings() along with some API cleanup. Expanding the tests
4599 for catch_warnings() also led to an improvement in the raising of a
4600 DeprecationWarning related to warnings.warn_explicit().
4601
Benjamin Peterson973e6c22008-09-01 23:12:58 +00004602- The deprecation warnings for the old camelCase threading API were removed.

4624
Amaury Forgeot d'Arc293924b2008-09-02 23:19:56 +00004625- Issue #2975: When compiling several extension modules with Visual Studio 2008
4626 from the same python interpreter, some environment variables would grow
4627 without limit.
4628
Benjamin Peterson37346b22008-08-23 20:27:43 +00004629- Issue #3643: Added a few more checks to _testcapi to prevent segfaults by
4630 exploitation of poor argument checking.
4631
Gerhard Häringef2276b2008-09-12 13:54:06 +00004632- sqlite3: Changed docstring of iterdump() to mark method as "Non-standard".

Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00004666What's New in Python 2.6 beta 3?
4667================================
4668
Barry Warsaw07a4a382008-08-21 01:15:08 +00004669*Release date: 20-Aug-2008*
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00004670
4671Core and Builtins
4672-----------------
4673
Guido van Rossumf8402962008-08-20 15:01:50 +00004674- Issue #1878: Remove Py_TPFLAGS_HAVE_VERSION_TAG from
4675 Py_TPFLAGS_DEFAULT when not building the core. This means 3rd party
4676 extensions do not automatically benefit from the class attribute
4677 cache; they will have to explicitly add Py_TPFLAGS_HAVE_VERSION_TAG
4678 to their tp_flags field if they care. This is a backwards
4679 compatibility feature; in 3.0, all types will use the cache by
4680 default.
4681
Benjamin Petersonf647dc12008-08-20 01:27:30 +00004682- Keyword arguments can now follow starred arguments. (``f(a, *args,
4683 keyword=23)`` is now valid syntax.)
4684
Thomas Heller0ad5ae02008-08-19 19:25:04 +00004685- ctypes function pointers that are COM methods have a boolean True
4686 value again.
4687
Martin v. Löwisf91d46a2008-08-12 14:49:50 +00004688- Issue #3139: Make buffer-interface thread-safe wrt. PyArg_ParseTuple,
4689 by denying s# to parse objects that have a releasebuffer procedure,
4690 and introducing s*.
4691
Georg Brandl1e13ea92008-08-11 09:07:59 +00004692- Issue #3537: Fix an assertion failure when an empty but presized dict
4693 object was stored in the freelist.
4694
Mark Dickinsonb6467572008-08-04 21:30:09 +00004695- Issue #1481296: Make long(float('nan')) and int(float('nan')) raise
4696 ValueError consistently across platforms.
4697
Amaury Forgeot d'Arc39fd6722008-07-31 21:28:03 +00004698- Issue #3479: On platforms where sizeof(int) is smaller than sizeof(long)
4699 (64bit Unix, for example), unichr() would truncate its argument and return
4700 u'\x00' for unichr(2**32). Now it properly raises an OverflowError.
4701
Neal Norwitze7d8be82008-07-31 17:17:14 +00004702- Apply security patches from Apple.
4703
Amaury Forgeot d'Arc246daed2008-07-31 00:42:16 +00004704- Issue #2542: Now that issubclass() may call arbitrary code, ensure that
4705 PyErr_ExceptionMatches returns 0 when an exception occurs there.
4706
Antoine Pitrou92f82162008-07-25 22:22:08 +00004707- Issue #1819: function calls with several named parameters are now on
4708 average 35% faster (as measured by pybench).
4709
Amaury Forgeot d'Arce4921fe2008-07-21 22:00:38 +00004710- Issue #2378: An unexpected UnboundLocalError or NameError could appear when
4711 the python debugger steps into a class statement: the free variables (local
4712 variables defined in an outer scope) would be deleted from the outer scope.
4713
Gregory P. Smith0470bab2008-07-22 04:46:32 +00004714- Issue #2620: Overflow checking when allocating or reallocating memory
4715 was not always being done properly in some python types and extension
4716 modules. PyMem_MALLOC, PyMem_REALLOC, PyMem_NEW and PyMem_RESIZE have
4717 all been updated to perform better checks and places in the code that
4718 would previously leak memory on the error path when such an allocation
4719 failed have been fixed.

4722-------
4723
Hirokazu Yamamoto838c79f2008-08-20 13:14:07 +00004724- Issue #3612: Added some missing basic types in ctypes.wintypes.
4725
Benjamin Petersone977ad42008-08-20 01:42:01 +00004726- The methods ``is_in_tuple()``, ``is_vararg()``, and ``is_keywordarg()`` of
4727 symtable.Symbol have been deprecated for removal in 3.0 and the next release.
4728
Amaury Forgeot d'Arc351ffb82008-08-18 19:23:47 +00004729- Issue #2234: distutils failed for some versions of the cygwin compiler. The
4730 version reported by these tools does not necessarily follow the python
4731 version numbering scheme, so the module is less strict when parsing it.
4732
Nick Coghlanf70385a2008-08-18 12:42:46 +00004733- Issue #2235: Added Py3k warnings for types which will become unhashable
4734 under the stricter __hash__ inheritance rules in 3.0. Several types
4735 which did not meet the rules for hash invariants and were already
4736 unhashable in 3.0 have now been explicitly flagged as unhashable in
4737 2.6 as well (collections.Mapping, collections.Set, unittest.TestSuite,
4738 xml.dom.minidom.NamedNodeMap, numbers.Number, UserList.UserList)
4739
Brett Cannon88f801d2008-08-18 00:46:22 +00004740- Update __all__ for cookielib, csv, os, urllib2, and weakref to include things

4742
Brett Cannon7b96f072008-08-18 00:41:11 +00004743- Remove an unneeded import of abc.ABCMeta from 'inspect'.
4744
Brett Cannon46225e72008-08-18 00:36:52 +00004745- Remove unneeded imports of 'sys' and 'warnings' from 'io'.

Brett Cannon25c9d6a2008-08-17 22:10:11 +00004747- Remove unneeded imports of 'warnings' from shelve, filecmp, and dummy_thread.
4748
Hirokazu Yamamoto41a81eb2008-08-17 13:10:46 +00004749- Issue #3575: Incremental decoder's decode function now takes bytearray
4750 by using 's*' instead of 't#'.
4751
Mark Dickinson3e4caeb2009-02-21 20:27:01 +00004752- Issue #2222: Fixed reference leak when occurred os.rename()
Hirokazu Yamamoto7f30a682008-08-17 09:46:56 +00004753 fails unicode conversion on 2nd parameter. (windows only)
4754
Georg Brandl222e2082010-08-01 22:27:39 +00004755- Issue #2464: urllib2 now supports a malformation in the URL received
Facundo Batista94f243a2008-08-17 03:38:39 +00004756 in a redirect.
4757
Brett Cannonabe423e2008-08-16 21:47:07 +00004758- Silence the DeprecationWarning raised when importing mimetools in
Brett Cannon721b1452008-08-16 22:00:27 +00004759 BaseHTTPServer, cgi (and rfc822), httplib.
Brett Cannonabe423e2008-08-16 21:47:07 +00004760
Facundo Batistaeb90b782008-08-16 14:44:07 +00004761- Issue #2776: fixed small issue when handling an URL with double slash
4762 after a 302 response in the case of not going through a proxy.
4763
Antoine Pitroub90a8be2008-08-15 21:03:21 +00004764- Issue #2676: in the email package, content-type parsing was hanging on
4765 pathological input because of quadratic or exponential behaviour of a
4766 regular expression.
4767
Antoine Pitrou11ec65d2008-08-14 21:04:30 +00004768- Issue #3476: binary buffered reading through the new "io" library is now
4769 thread-safe.
4770
Brett Cannonbf3157b2008-08-14 05:00:03 +00004771- Silence the DeprecationWarning of rfc822 when it is imported by mimetools
4772 since mimetools itself is deprecated. Because modules are cached, all
4773 subsequent imports of rfc822 will not raise a visible DeprecationWarning.
4774
Antoine Pitrou9fcd4b32008-08-11 17:21:36 +00004775- Issue #3134: shutil referenced undefined WindowsError symbol.
4776
Robert Schuppenies14646332008-08-10 11:01:53 +00004777- Issue #1342811: Fix leak in Tkinter.Menu.delete. Commands associated to
4778 menu entries were not deleted.
4779
Brett Cannon83e81842008-08-09 23:30:55 +00004780- Copied the implementation of reduce() to _functools.reduce() to have a
4781 version that did not raise a DeprecationWarning under -3.
4782
Antoine Pitrou76b8bee2008-08-09 17:27:23 +00004783- Issue #3205: When iterating over a BZ2File fails allocating memory, raise
4784 a MemoryError rather than silently stop the iteration.
4785
Guido van Rossum59ce9012008-08-09 14:55:34 +00004786- Issue #3487: sre "bytecode" validator. Passing invalid "re-bytecode"
4787 to _sre.compile() will now be rejected. This should not affect anybody
4788 since the re.compile() function never generates invalid re-bytecode.
4789
Skip Montanaroa032bf42008-08-08 22:52:51 +00004790- Issue #3436: Make csv.DictReader's fieldnames attribute a property so that
4791 upon first access it can be automatically initialized from the csv file if
4792 it wasn't initialized during instantiation.
4793
Brett Cannon3aa2a492008-08-06 22:28:09 +00004794- Issue #2338: Create imp.reload() to help with transitioning to Python 3.0 as
4795 the reload() built-in has been removed.
4796
Brett Cannon7e30b672008-08-04 21:52:25 +00004797- Changed code in the following modules/packages to remove warnings raised
Brett Cannonc1b76e42008-08-09 23:06:16 +00004798 while running under the ``-3`` flag: aifc, asynchat, asyncore, bdb, bsddb,

Antoine Pitroude781a42008-08-09 12:43:23 +00004809 asking for a specific length. This problem only affected files opened
4810 using the new "io" module, not the built-in open() function.
Benjamin Peterson01a24322008-07-28 23:35:27 +00004811

4836 file name rather than a ZipInfo instance, so files are extracted with
4837 mode 0600 rather than 000 under Unix.

Gregory P. Smitha36f8fe2008-08-04 00:13:29 +00004839- Issue #1857: subprocess.Popen.poll gained an additional _deadstate keyword
4840 argument in python 2.5, this broke code that subclassed Popen to include its
4841 own poll method. Fixed my moving _deadstate to an _internal_poll method.

4853
Nick Coghlan2a0c2b12008-08-04 12:47:17 +00004854- Issue #643841: The language reference now provides more detailed
4855 coverage of the lookup process for special methods. The disclaimers
4856 regarding lack of coverage of new-style classes have also been
4857 removed, since the coverage is now fairly reasonable.

4861================================
4862
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00004863*Release date: 17-Jul-2008*
4864
Raymond Hettingere3ae6552008-06-20 04:18:15 +00004865Core and Builtins
4866-----------------
4867
Georg Brandl3e483f62008-07-16 22:57:41 +00004868- Issue #3156: Fix inconsistent behavior of the bytearray type: all
4869 its methods now allow for items objects that can be converted to
4870 an integer using operator.index().
4871
Mark Dickinson64b7e502008-07-16 09:40:03 +00004872- Issue #3360: Fix incorrect parsing of '020000000000.0', which
4873 produced a ValueError instead of giving the correct float.
4874
Eric Smitha5fa5a22008-07-16 00:11:49 +00004875- Issue #3083: Add alternate (#) formatting for bin, oct, hex output
4876 for str.format(). This adds the prefix 0b, 0o, or 0x, respectively.
4877
Mark Dickinson7103aa42008-07-15 19:08:33 +00004878- Issue #3008: the float type has a new instance method 'float.hex'
4879 and a new class method 'float.fromhex' to convert floating-point
4880 numbers to and from hexadecimal strings, respectively.
4881
Nick Coghlan6d6bd442008-07-15 15:40:22 +00004882- Issue #2235: __hash__ is once again inherited by default. To allow
4883 collections.Hashable to remain meaningful in the presence of the
4884 default hash implementation (object.__hash__), it is now possible
4885 to explicit block inheritance of hash by setting __hash__=None at
4886 the Python level, or tp_hash=PyObject_HashNotImplemented at the C
4887 level.
4888
Nick Coghlanb028f502008-07-13 14:52:36 +00004889- Issue #3221: Issue a RuntimeWarning instead of raising SystemError if
4890 the parent module cannot be found while performing an absolute import.
4891 This means that an incorrectly defined __package__ attribute will
4892 now only prevent relative imports in that module rather than causing
4893 all imports from that module to fail.
4894
Nick Coghlan14ff9942008-07-08 14:21:42 +00004895- Issue #2517: Allow unicode messages in Exceptions again by correctly
4896 bypassing the instance dictionary when looking up __unicode__ on
4897 new-style classes.

Amaury Forgeot d'Arcbdd941f2008-07-01 20:38:04 +00004899- Issue #3242: Fix a crash inside the print statement, if sys.stdout is
4900 set to a custom object whose write() method happens to install
4901 another file in sys.stdout.
4902
Amaury Forgeot d'Arc1f40c8a2008-06-30 22:42:40 +00004903- Issue #3088: Corrected a race condition in classes derived from
4904 threading.local: the first member set by a thread could be saved in
4905 another thread's dictionary.
4906
Mark Dickinson1ec2fcd2008-06-20 14:53:43 +00004907- Issue #3004: Minor change to slice.indices(): the start and stop
4908 arguments are now treated identically, making the behaviour easier
4909 to describe and understand. For example, slice(None, -10,
4910 1).indices(9) now returns (0, 0, 1) instead of (0, -1, 1), and
4911 slice(None, 10, -1).indices(10) returns (9, 9, -1) instead of (9,
4912 10, -1).
4913
Georg Brandl278fc502008-07-19 12:46:12 +00004914- Issue #3219: Calling a function with repeated keyword arguments,
4915 f(a=2, a=23), would not cause a syntax error. This was a regression
4916 from 2.4 caused by the switch to the new compiler.
Benjamin Peterson175e4d92008-07-01 19:34:52 +00004917
Georg Brandl278fc502008-07-19 12:46:12 +00004918- Issue #2862: Make int and float freelist management consistent with
4919 other freelists. Changes their CompactFreeList apis into
4920 ClearFreeList apis and calls them via gc.collect().

4926 api functions without holding the GIL, which could lead to a fatal
4927 error when they failed.
4928
Martin v. Löwisaabf4042008-08-02 07:20:25 +00004929- Issue #799428: Fix Tkinter.Misc._nametowidget to unwrap Tcl command objects.

Andrew M. Kuchlingcc3f2b12008-07-10 14:43:31 +00004952- Issue #3301: Bisect module behaved badly when lo was negative.
Raymond Hettinger3cd1e422008-07-10 14:03:19 +00004953
Amaury Forgeot d'Arc0f7cddc2008-07-06 21:34:39 +00004954- Issue #839496: SimpleHTTPServer used to open text files in text mode. This is
4955 both unnecessary (HTTP allows text content to be sent in several forms) and
Andrew M. Kuchlingcc3f2b12008-07-10 14:43:31 +00004956 wrong because the actual transmitted size could differ from the
Amaury Forgeot d'Arc0f7cddc2008-07-06 21:34:39 +00004957 content-length. The problem had been corrected in the 2.4 branch, but never
4958 merged into trunk.
4959

Nick Coghlanc060b0e2008-07-02 13:09:19 +00004973- Issue #3190: Pydoc now hides the automatic module attribute __package__ (the
4974 handling is now the same as that of other special attributes like __name__).
4975
Brett Cannon8bb8fa52008-07-02 01:57:08 +00004976- Issue #2885 (partial): The urllib.urlopen() function has been deprecated for

5429 original Python code has been kept as backup). This will allow for
5430 using the 'warning's machinery in such places as the parser where
5431 use of pure Python code is not possible. Both the ``showarning()``
5432 and ``formatwarning()`` gain an optional 'line' argument which is
5433 not called by default for backwards-compatibility reasons. Setting
5434 ``warnings.showwarning()`` to an implementation that lacks support
5435 for the ``line`` argument will raise a DeprecationWarning.

Georg Brandl3ee81df2008-05-17 18:14:43 +00005498- Issue #2550: The approach used by client/server code for obtaining
5499 ports to listen on in network-oriented tests has been refined in an
5500 effort to facilitate running multiple instances of the entire
5501 regression test suite in parallel without issue.
5502 test_support.bind_port() has been fixed such that it will always
5503 return a unique port -- which wasn't always the case with the
5504 previous implementation, especially if socket options had been set
5505 that affected address reuse (i.e. SO_REUSEADDR, SO_REUSEPORT). The
5506 new implementation of bind_port() will actually raise an exception
5507 if it is passed an AF_INET/SOCK_STREAM socket with either the
5508 SO_REUSEADDR or SO_REUSEPORT socket option set. Furthermore, if
5509 available, bind_port() will set the SO_EXCLUSIVEADDRUSE option on
5510 the socket it's been passed. This currently only applies to
5511 Windows. This option prevents any other sockets from binding to the
5512 host/port we've bound to, thus removing the possibility of the
5513 'non-deterministic' behaviour, as Microsoft puts it, that occurs
5514 when a second SOCK_STREAM socket binds and accepts to a host/port
5515 that's already been bound by another socket. The optional preferred
5516 port parameter to bind_port() has been removed. Under no
5517 circumstances should tests be hard coding ports!
5518
5519 test_support.find_unused_port() has also been introduced, which will
5520 pass a temporary socket object to bind_port() in order to obtain an
5521 unused port. The temporary socket object is then closed and
5522 deleted, and the port is returned. This method should only be used
5523 for obtaining an unused port in order to pass to an external program
5524 (i.e. the -accept [port] argument to openssl's s_server mode) or as
5525 a parameter to a server-oriented class that doesn't give you direct
5526 access to the underlying socket used.
5527
5528 Finally, test_support.HOST has been introduced, which should be used
5529 for the host argument of any relevant socket calls (i.e. bind and
5530 connect).
Trent Nelsone41b0062008-04-08 23:47:30 +00005531
5532 The following tests were updated to following the new conventions:
Georg Brandl3ee81df2008-05-17 18:14:43 +00005533 test_socket, test_smtplib, test_asyncore, test_ssl, test_httplib,
Trent Nelsone41b0062008-04-08 23:47:30 +00005534 test_poplib, test_ftplib, test_telnetlib, test_socketserver,
5535 test_asynchat and test_socket_ssl.
5536
Georg Brandl3ee81df2008-05-17 18:14:43 +00005537 It is now possible for multiple instances of the regression test
5538 suite to run in parallel without issue.

Eric Smitha73fbe72008-02-23 03:09:44 +00005817- Added the future_builtins module, which contains hex() and oct().
5818 These are the PEP 3127 version of these functions, designed to be
5819 compatible with the hex() and oct() builtins from Python 3.0. They
5820 differ slightly in their output formats from the existing, unchanged
5821 Python 2.6 builtins. The expected usage of the future_builtins
5822 module is:
5823 from future_builtins import hex, oct
5824
Eric Smith7ef40bf2008-02-20 23:34:22 +00005825- Issue #1600: Modifed PyOS_ascii_formatd to use at most 2 digit
5826 exponents for exponents with absolute value < 100. Follows C99
5827 standard. This is a change on Windows, which would use 3 digits.
5828 Also, added 'n' to the formats that PyOS_ascii_formatd understands,
5829 so that any alterations it does to the resulting string will be
5830 available in stringlib/formatter.h (for float.__format__).
5831
Eric Smith5a3c1352008-02-19 13:21:56 +00005832- Implemented PEP 3101, Advanced String Formatting. This adds a new
5833 builtin format(); a format() method for str and unicode; a
5834 __format__() method to object, str, unicode, int, long, float, and
5835 datetime; the class string.Formatter; and the C API
5836 PyObject_Format().
5837
Georg Brandl3ee81df2008-05-17 18:14:43 +00005838- Fixed several potential crashes, all caused by specially crafted
5839 __del__ methods exploiting objects in temporarily inconsistent
5840 state.
Amaury Forgeot d'Arc632fad32008-02-16 20:55:24 +00005841
Vinay Sajipb7edfc42008-04-02 21:10:23 +00005842- Issue #2115: Important speedup in setting __slot__ attributes. Also
Georg Brandl3ee81df2008-05-17 18:14:43 +00005843 prevent a possible crash: an Abstract Base Class would try to access
5844 a slot on a registered virtual subclass.

5850 in order to allow pymalloc to free more arenas. Python may give back
5851 memory to the OS earlier.
Christian Heimes3b718a72008-02-14 12:47:33 +00005852
Georg Brandl3ee81df2008-05-17 18:14:43 +00005853- Issue #2045: Fix an infinite recursion triggered when printing a
5854 subclass of collections.defaultdict, if its default_factory is set
5855 to a bound method.
Amaury Forgeot d'Arcb01aa432008-02-08 00:56:02 +00005856
Christian Heimesf75dbef2008-02-08 00:11:31 +00005857- Fixed a minor memory leak in dictobject.c. The content of the free
5858 list was not freed on interpreter shutdown.
5859
Georg Brandl21e99f42010-03-07 15:23:59 +00005860- Limit free list of method and built-in function objects to 256

5864 functions ``PyInt_CompactFreeList`` and ``PyFloat_CompactFreeList``
Christian Heimes422051a2008-02-04 18:00:12 +00005865 to compact the internal free lists of pre-allocted ints and floats.
5866
Georg Brandl3ee81df2008-05-17 18:14:43 +00005867- Issue #1983: Fixed return type of fork(), fork1() and forkpty()
5868 calls. Python expected the return type int but the fork familie
5869 returns pi_t.
Christian Heimes951cc0f2008-01-31 23:08:23 +00005870

Georg Brandl3ee81df2008-05-17 18:14:43 +00005883- Patch #1473257: generator objects gain a gi_code attribute. This is
5884 the same object as the func_code attribute of the function that
5885 produced the generator.
Georg Brandl0cdf9a32008-01-26 14:14:20 +00005886
Georg Brandl3ee81df2008-05-17 18:14:43 +00005887- Issue #1920: "while 0" statements were completely removed by the
5888 compiler, even in the presence of an "else" clause, which is
5889 supposed to be run when the condition is false. Now the compiler
5890 correctly emits bytecode for the "else" suite.
Amaury Forgeot d'Arc31eaafe2008-01-24 22:59:25 +00005891

5899
Georg Brandl3ee81df2008-05-17 18:14:43 +00005900- Issue #1915: Python compiles with --enable-unicode=no again. However
Christian Heimes082c9b02008-01-23 14:20:50 +00005901 several extension methods and modules do not work without unicode

Georg Brandl3ee81df2008-05-17 18:14:43 +00005918- Objects/structseq.c: Implemented new structseq representation. The
5919 patch makes structseqs (e.g. the return value of os.stat) more
5920 readable.
Christian Heimes9c201962008-01-14 03:33:52 +00005921
Georg Brandl3ee81df2008-05-17 18:14:43 +00005922- Patch #1700288: added a type attribute cache that caches method
5923 accesses, resulting in speedups in heavily object-oriented code.
Amaury Forgeot d'Arce4c270c2008-01-14 00:29:41 +00005924
Neal Norwitz3fc15b82008-01-10 05:42:58 +00005925- Bug #1776: __import__() no longer accepts filenames on any platform.
5926 The first parameter to __import__() must be a valid module name.

Georg Brandlaed6c662008-01-07 17:25:53 +00005928- Patch #1668: renamed THREADDEBUG envvar to PYTHONTHREADDEBUG.
5929
Georg Brandl3ee81df2008-05-17 18:14:43 +00005930- Patch #602345: Add -B command line option, PYTHONDONTWRITEBYTECODE
5931 envvar and sys.dont_write_bytecode attribute. All these can be set
5932 to forbid Python to attempt to write compiled bytecode files.
Georg Brandl2da0fce2008-01-07 17:09:35 +00005933
Georg Brandl3ee81df2008-05-17 18:14:43 +00005934- Improve some exception messages when Windows fails to load an
5935 extension module. Now we get for example '%1 is not a valid Win32
5936 application' instead of 'error code 193'.

Christian Heimes0a8143f2007-12-18 23:22:54 +00005943- Issue #1635: Platform independent creation and representation of NaN
Georg Brandl3ee81df2008-05-17 18:14:43 +00005944 and INF. float("nan"), float("inf") and float("-inf") now work on
5945 every platform with IEEE 754 semantics.

Georg Brandl3ee81df2008-05-17 18:14:43 +00005947- Compiler now generates simpler and faster code for dictionary
5948 literals. The oparg for BUILD_MAP now indicates an estimated
5949 dictionary size. There is a new opcode, STORE_MAP, for adding
5950 entries to the dictionary.

Georg Brandl3ee81df2008-05-17 18:14:43 +00005979- Patch #1739468: Directories and zipfiles containing a __main__.py
5980 file can now be directly executed by passing their name to the
5981 interpreter. The directory/zipfile is automatically inserted as the
5982 first entry in sys.path.

Georg Brandl3ee81df2008-05-17 18:14:43 +00005984- Issue #1265: Fix a problem with sys.settrace, if the tracing
5985 function uses a generator expression when at the same time the
5986 executed code is closing a paused generator.
Amaury Forgeot d'Arc0d75f092007-11-13 21:54:28 +00005987
Raymond Hettinger1760c8a2007-11-08 02:52:43 +00005988- sets and frozensets now have an isdisjoint() method.

5993
Georg Brandl21e99f42010-03-07 15:23:59 +00005994- The enumerate() built-in function is no longer bounded to sequences
Georg Brandl3ee81df2008-05-17 18:14:43 +00005995 smaller than LONG_MAX. Formerly, it raised an OverflowError. Now,
5996 automatically shifts from ints to longs.
Raymond Hettinger8f669372007-10-03 21:18:11 +00005997
Georg Brandl3ee81df2008-05-17 18:14:43 +00005998- Issue #1686386: Tuple's tp_repr did not take into account the
5999 possibility of having a self-referential tuple, which is possible
6000 from C code. Nor did object's tp_str consider that a type's tp_str
6001 could do something that could lead to an inifinite recursion.
6002 Py_ReprEnter() and Py_EnterRecursiveCall(), respectively, fixed the
6003 issues.
Brett Cannon0b14f242007-09-30 19:45:10 +00006004
Georg Brandl3ee81df2008-05-17 18:14:43 +00006005- Issue #1164: It was possible to trigger deadlock when using the
6006 'print' statement to write to a file since the GIL was not released
6007 as needed. Now PyObject_Print() does the right thing along with
6008 various tp_print implementations of the built-in types and those in
6009 the collections module.
Brett Cannon01531592007-09-17 03:28:34 +00006010
Georg Brandl3ee81df2008-05-17 18:14:43 +00006011- Issue #1147: Exceptions were directly allowing string exceptions in

Brett Cannona0c05512007-09-10 21:38:27 +00006017
Brett Cannon1e534b52007-09-07 04:18:30 +00006018- Issue #1202533: Fix infinite recursion calls triggered by calls to
Georg Brandl3ee81df2008-05-17 18:14:43 +00006019 PyObject_Call() never calling back out to Python code to trigger
6020 recursion depth updates/checks. Required the creation of a static
6021 RuntimeError instance in case normalizing an exception put the
6022 recursion check value past its limit. Fixes crashers
6023 infinite_rec_(1|2|4|5).py.
Brett Cannon1e534b52007-09-07 04:18:30 +00006024

Neal Norwitz0ac60192007-05-27 04:08:54 +00006038- Add new attribute names for function objects. All the func_* become
Georg Brandl3ee81df2008-05-17 18:14:43 +00006039 __*__ attributes. (Some already existed, e.g., __doc__ and
6040 __name__.)
Neal Norwitz0ac60192007-05-27 04:08:54 +00006041
Neal Norwitz8b2bfbc2007-05-23 06:35:32 +00006042- Add -3 option to the interpreter to warn about features that are
6043 deprecated and will be changed/removed in Python 3.0.
6044
Georg Brandl2134e752007-05-21 20:34:16 +00006045- Patch #1686487: you can now pass any mapping after '**' in function
6046 calls.
6047
Collin Winter62903052007-05-18 23:11:24 +00006048- except clauses may now be spelled either "except E, target:" or
Georg Brandl3ee81df2008-05-17 18:14:43 +00006049 "except E as target:". This is to provide forwards compatibility
6050 with Python 3.0.

Vinay Sajip8549ce32007-05-06 17:53:37 +00006057- When __slots__ are set to a unicode string, make it work the same as
Neal Norwitzcbd9ee62007-04-14 05:25:50 +00006058 setting a plain string, ie don't expand to single letter identifiers.
6059
Raymond Hettinger13936692007-04-11 18:40:58 +00006060- Request #1191699: Slices can now be pickled.
6061
Raymond Hettinger4db5fe92007-04-12 04:10:00 +00006062- Request #1193128: str.translate() now allows a None argument for
6063 translations that only remove characters without re-mapping the
6064 remaining characters.
6065
Georg Brandl5cb76c12007-03-21 09:00:39 +00006066- Patch #1682205: a TypeError while unpacking an iterable is no longer

6070
Guido van Rossum143b5642007-03-23 04:58:42 +00006071- Bug #1683368: The object.__init__() and object.__new__() methods are
6072 now stricter in rejecting excess arguments. The only time when
6073 either allows excess arguments is when it is not overridden and the
6074 other one is. For backwards compatibility, when both are
6075 overridden, it is a deprecation warning (for now; maybe a Py3k
Guido van Rossum234b1ff2007-03-23 19:39:01 +00006076 warning later). Also, type.__init__() insists on the same signature
6077 as supported by type.__new__().
Guido van Rossum143b5642007-03-23 04:58:42 +00006078
Georg Brandl3ee81df2008-05-17 18:14:43 +00006079- Patch #1675423: PyComplex_AsCComplex() now tries to convert an
6080 object to complex using its __complex__() method before falling back
6081 to the __float__() method. Therefore, the functions in the cmath
6082 module now can operate on objects that define a __complex__()
6083 method.

6100
Georg Brandl7b9c5552007-03-12 14:30:05 +00006101- Bug #1678647: write a newline after printing an exception in any
6102 case, even when converting the value to a string failed.
6103
Georg Brandl871f1bc2007-03-12 13:17:36 +00006104- The dir() function has been extended to call the __dir__() method on
Georg Brandl3ee81df2008-05-17 18:14:43 +00006105 its argument, if it exists. If not, it will work like before. This
6106 allows customizing the output of dir() in the presence of a
6107 __getattr__().

6116 parthensized forms. This means complex(repr(x)) now works instead of
6117 raising a ValueError.
Collin Wintere38051d2007-03-09 20:33:07 +00006118
Georg Brandlaa2321b2007-03-07 00:40:28 +00006119- Patch #703779: unset __file__ in __main__ after running a file. This
Georg Brandl3ee81df2008-05-17 18:14:43 +00006120 makes the filenames the warning module prints much more sensible
6121 when a PYTHONSTARTUP file is used.

Georg Brandl0fca97a2007-03-05 22:28:08 +00006134- Patch #1674228: when assigning a slice (old-style), check for the
6135 sq_ass_slice instead of the sq_slice slot.
6136
Georg Brandl3ee81df2008-05-17 18:14:43 +00006137- When printing an unraisable error, don't print exceptions. before

Facundo Batistab6a5c9d2007-03-29 18:22:35 +00006641- Added a timeout parameter to the constructor of other protocols
6642 (telnetlib, ftplib, smtplib and poplib). This is second part of the
6643 work started with create_connection() and timeout in httplib, and
6644 closes patch #723312.
6645
Vinay Sajip8549ce32007-05-06 17:53:37 +00006646- Patch #1676823: Added create_connection() to socket.py, which may be
6647 called with a timeout, and use it from httplib (whose HTTPConnection
Facundo Batista70f996b2007-05-21 17:32:32 +00006648 and HTTPSConnection now accept an optional timeout).
Facundo Batista07c78be2007-03-23 18:54:07 +00006649

6670
Georg Brandlf66b6032007-03-14 08:27:52 +00006671- Bug #767111: fix long-standing bug in urllib which caused an
Georg Brandl3ee81df2008-05-17 18:14:43 +00006672 AttributeError instead of an IOError when the server's response
6673 didn't contain a valid HTTP status line.
Georg Brandlf66b6032007-03-14 08:27:52 +00006674
Georg Brandl3ee81df2008-05-17 18:14:43 +00006675- Patch #957650: "%var%" environment variable references are now
6676 properly expanded in ntpath.expandvars(), also "~user" home

Georg Brandl3ee81df2008-05-17 18:14:43 +00006679- Patch #1429539: pdb now correctly initializes the __main__ module
6680 for the debugged script, which means that imports from __main__ work
Georg Brandlb6ae6aa2007-03-13 21:58:44 +00006681 correctly now.
6682
Georg Brandlbad6f192007-03-13 21:32:56 +00006683- The nonobvious commands.getstatus() function is now deprecated.

6689
Georg Brandl3ee81df2008-05-17 18:14:43 +00006690- Patch #1530482: add pydoc.render_doc() which returns the
6691 documentation for a thing instead of paging it to stdout, which

6700 parameter which can be set to False to prevent the default
6701 delete-on-close behavior.
Georg Brandl35ef9c12007-03-13 18:31:49 +00006702
Georg Brandl9e6b4702007-03-13 18:15:41 +00006703- Patch #1581073: add a flag to textwrap that prevents the dropping of
6704 whitespace while wrapping.
6705
Georg Brandl92a6bae2007-03-13 17:43:32 +00006706- Patch #1603688: ConfigParser.SafeConfigParser now checks values that
Georg Brandl3ee81df2008-05-17 18:14:43 +00006707 are set for invalid interpolation sequences that would lead to
6708 errors on reading back those values.
Georg Brandl92a6bae2007-03-13 17:43:32 +00006709

Georg Brandl3ee81df2008-05-17 18:14:43 +00006724 field names in its exception message if you try to write a record
6725 with a dictionary containing fields not in the CSV field names list.

6751 returned string up to the first NUL character.
6752

6762
Georg Brandl3ee81df2008-05-17 18:14:43 +00006763- unittest now verifies more of its assumptions. In particular,
6764 TestCase and TestSuite subclasses (not instances) are no longer
6765 accepted in TestSuite.addTest(). This should cause no
6766 incompatibility since it never made sense with ordinary subclasses
6767 -- the failure just occurred later, with a more cumbersome
6768 exception.

6777 given a unicode argument and os.listdir() returns unicode filenames.
6778
Georg Brandl3ee81df2008-05-17 18:14:43 +00006779- Patch #1673619: setup.py identifies extension modules it doesn't

Georg Brandl3ee81df2008-05-17 18:14:43 +00007157 time so that opening a database previously created with the DB_DUP
7158 or DB_DUPSORT flag set will keep the proper behavior on subsequent
7159 opens. Specifically: dictionary assignment to a DB object will
7160 replace all values for a given key when the database allows
7161 duplicate values. DB users should use DB.put(k, v) when they want
7162 to store duplicates; not DB[k] = v.

7169 characters with ASCII value less than 32. Also, it correctly quotes
7170 dots only if they occur on a single line, as opposed to the previous
7171 behavior of quoting dots if they are the second character of any
7172 line.
