189 by Andrew Bennetts.
190
Raymond Hettinger74f869e2010-09-13 22:14:36 +0000191- Issue #9826: OrderedDict.__repr__ can now handle self-referential

200 This prevents user-created self-referencing ordered dictionaries from
201 becoming permanently uncollectable GC garbage. The downside is that
202 removing __del__ means that the internal doubly-linked list has to wait for
203 GC collection rather than freeing memory immediately when the refcnt drops
204 to zero.
205
Raymond Hettingerffd2a422010-09-10 10:47:22 +0000206- Issue #9816: random.Random.jumpahead(n) did not produce a sufficiently

Raymond Hettingerffd2a422010-09-10 10:47:22 +0000208 value.
209
Antoine Pitrouc818ed42010-09-07 21:40:25 +0000210- Issue #9792: In case of connection failure, socket.create_connection()
211 would swallow the exception and raise a new one, making it impossible
212 to fetch the original errno, or to filter timeout errors. Now the
213 original error is re-raised.
214
Antoine Pitrouf4f61712010-09-07 16:34:47 +0000215- Issue #9758: When fcntl.ioctl() was called with mutable_flag set to True,
216 and the passed buffer was exactly 1024 bytes long, the buffer wouldn't
217 be updated back after the system call. Original patch by Brian Brazil.
218
Antoine Pitroudca9de92010-09-04 17:52:26 +0000219- Issue #1100562: Fix deep-copying of objects derived from the list and
220 dict types. Patch by Michele Orrù and Björn Lindqvist.
221

223 ConfigParser.write.
224
Daniel Stutzbach66c981b2010-08-31 20:29:39 +0000225- Issue #808164: Fixed socket.close to avoid references to globals, to
226 avoid issues when socket.close is called from a __del__ method.
227
Terry Reedyd2d2ae92010-11-11 23:22:19 +0000228- Issue #2986: difflib.SequenceMatcher gets a new parameter, autojunk, which

230 heuristic. Patch by Terry Reedy and Eli Bendersky

233 falling into recursion.
234
R. David Murray7c4bf552010-08-25 01:45:57 +0000235- Issue #1194222: email.utils.parsedate now returns RFC2822 compliant four
236 character years even if the message contains RFC822 two character years.
237
Daniel Stutzbach91287322010-08-24 21:09:30 +0000238- Issue #8750: Fixed MutableSet's methods to correctly handle
239 reflexive operations, namely x -= x and x ^= x.
240

251
Antoine Pitrou3ebaed62010-08-21 19:17:25 +0000252- Issue #9617: Signals received during a low-level write operation aren't
253 ignored by the buffered IO layer anymore.
254
Benjamin Peterson52c36052010-08-21 03:03:22 +0000255- Issue #2521: Use weakrefs on for caching in the abc module, so that classes
256 are not held onto after they are deleted elsewhere.
257
Raymond Hettingera54b2da2010-08-17 19:03:06 +0000258- Issue #9626: the view methods for collections.OrderedDict() were returning
259 the unordered versions inherited from dict. Those methods are now
260 overridden to provide ordered views.
261
Éric Araujo0389ae62010-08-14 03:07:46 +0000262- Issue #8688: MANIFEST files created by distutils now include a magic

272 when the underlying raw IO channel was e.g. a socket. Report and original
273 patch by Jason V. Miller.
274
Fred Drake0a1fa0e2010-08-10 13:09:54 +0000275- Issue #9551: Don't raise TypeError when setting the value to None for

661
Ezio Melottiab2eb0e2010-06-05 19:21:32 +0000662- Issue #8271: during the decoding of an invalid UTF-8 byte sequence, only the
663 start byte and the continuation byte(s) are now considered invalid, instead
664 of the number of bytes specified by the start byte.
665 E.g.: '\xf1\x80AB'.decode('utf-8', 'replace') now returns u'\ufffdAB' and
666 replaces with U+FFFD only the start byte ('\xf1') and the continuation byte
667 ('\x80') even if '\xf1' is the start byte of a 4-bytes sequence.
668 Previous versions returned a single u'\ufffd'.

Mark Dickinson23f0d6b2010-06-05 11:52:24 +0000670- Issue #8627: Remove bogus "Overriding __cmp__ blocks inheritance of
Mark Dickinsone4b83e02010-06-05 12:14:43 +0000671 __hash__ in 3.x" warning. Also fix "XXX undetected error" that
672 arises from the "Overriding __eq__ blocks inheritance ..." warning
673 when turned into an exception: in this case the exception simply
674 gets ignored.

Mark Dickinson4ca7c3c2010-05-30 13:18:10 +0000676- Issue #8748: Fix two issues with comparisons between complex and integer
677 objects. (1) The comparison could incorrectly return True in some cases
678 (2**53+1 == complex(2**53) == 2**53), breaking transivity of equality.
679 (2) The comparison raised an OverflowError for large integers, leading
680 to unpredictable exceptions when combining integers and complex objects
681 in sets or dicts.
682
Mark Dickinson81336372010-05-30 12:12:25 +0000683- Issue #5211: Implicit coercion for the complex type is now completely
684 removed. (Coercion for arithmetic operations was already removed in 2.7
685 alpha 4, but coercion for rich comparisons was accidentally left in.)
686
Victor Stinnerc49dfcc2010-05-25 22:30:32 +0000687- Issue #3798: Write sys.exit() message to sys.stderr to use stderr encoding

1064 with a non-empty format string. This is an effort to future-proof user
1065 code. If a derived class does not currently implement __format__ but later
1066 adds its own __format__, it would most likely break user code that had
1067 supplied a format string. This will be changed to a DeprecationWaring in
1068 Python 3.3 and it will be an error in Python 3.4.

Georg Brandlba83f822010-03-14 09:50:54 +00001501- Issue #7561: Operations on empty bytearrays (such as ``int(bytearray())``)
1502 could crash in many places because of the ``PyByteArray_AS_STRING()`` macro
1503 returning NULL. The macro now returns a statically allocated empty string
1504 instead.

1514 strings,
1515 (2) a crash in dtoa.c that occurred in debug builds when parsing certain long
1516 numeric strings corresponding to subnormal values,
1517 (3) a memory leak for some values large enough to cause overflow, and
1518 (4) a number of flaws that could lead to incorrectly rounded results.

Antoine Pitroud840e512010-02-04 20:20:18 +00001549- Issue #4772: Raise a ValueError when an unknown Bluetooth protocol is
Georg Brandlba83f822010-03-14 09:50:54 +00001550 specified, rather than fall through to AF_PACKET (in the ``socket`` module).
Antoine Pitroud840e512010-02-04 20:20:18 +00001551 Also, raise ValueError rather than TypeError when an unknown TIPC address

Georg Brandlba83f822010-03-14 09:50:54 +00001557 file position when calling `truncate()`. It would previously change the file
1558 position to the given argument, which goes against the tradition of
Antoine Pitrouf3fa0742010-01-31 22:26:04 +00001559 ftruncate() and other truncation APIs. Patch by Pascal Chambon.

1562 class used to represent files stored inside an archive. The new
1563 implementation is significantly faster and can be wrapped in a
1564 ``io.BufferedReader`` object for more speedups. It also solves an issue
1565 where interleaved calls to ``read()`` and ``readline()`` give wrong results.

Georg Brandlba83f822010-03-14 09:50:54 +00001576- Issue #7748: Since unicode values are supported for some metadata options in
1577 Distutils, the DistributionMetadata get_* methods will now return an utf-8
1578 encoded string for them. This ensures that the upload and register commands
1579 send the correct values to PyPI without any error.

1654-----------------
1655
Georg Brandlba83f822010-03-14 09:50:54 +00001656- The ``__complex__()`` method is now looked up on the class of instances to
1657 make it consistent with other special methods.

1661
Mark Dickinson1b34d252010-01-01 17:27:30 +00001662- Issue #5080: A number of functions and methods previously produced a
Georg Brandlba83f822010-03-14 09:50:54 +00001663 DeprecationWarning when passed a float argument where an integer was expected.
1664 These functions and methods now raise TypeError instead. The majority of the
1665 effects of this change are in the extension modules, but some core functions
1666 and methods are affected: notably the 'chr', 'range' and 'xrange' builtins,
1667 and many unicode/str methods.

1681 of integers: the result of a/b is now correctly rounded for ints a and b (at
1682 least on IEEE 754 platforms), and in particular does not depend on the
1683 internal representation of a long.

1691
Georg Brandlba83f822010-03-14 09:50:54 +00001692 These executables now work properly with the arch(1) command: ``arch -ppc
1693 python`` will start a universal binary version of python in PPC mode (unlike

1841 significant digits instead.

Georg Brandlba83f822010-03-14 09:50:54 +00001850- Issue #7117: ``repr(x)`` for a float x returns a result based on the shortest
1851 decimal string that's guaranteed to round back to x under correct rounding
1852 (with round-half-to-even rounding mode). Previously it gave a string based on
1853 rounding x to 17 decimal digits. repr(x) for a complex number behaves
1854 similarly. On platforms where the correctly-rounded strtod and dtoa code is
1855 not supported (see below), repr is unchanged.

Georg Brandlba83f822010-03-14 09:50:54 +00001857- Issue #7117: On almost all platforms: float-to-string and string-to-float
1858 conversions within Python are now correctly rounded. Places these conversions
1859 occur include: str for floats and complex numbers; the float and complex
1860 constructors; old-style and new-style numeric formatting; serialization and
1861 deserialization of floats and complex numbers using marshal, pickle and json;
1862 parsing of float and imaginary literals in Python code; Decimal-to-float
1863 conversion.
Mark Dickinsonb678de82009-11-19 18:41:49 +00001864
Georg Brandlba83f822010-03-14 09:50:54 +00001865 The conversions use a Python-adapted version of David Gay's well-known dtoa.c,
1866 providing correctly-rounded strtod and dtoa C functions. This code is
1867 supported on Windows, and on Unix-like platforms using gcc, icc or suncc as
1868 the C compiler. There may be a small number of platforms on which correct
1869 operation of this code cannot be guaranteed, so the code is not used: notably,
1870 this applies to platforms where the C double format is not IEEE 754 binary64,
1871 and to platforms on x86 hardware where the x87 FPU is set to 64-bit precision
1872 and Python's configure script is unable to determine how to change the FPU
1873 precision. On these platforms conversions use the platform strtod and dtoa,
1874 as before.

Georg Brandlba83f822010-03-14 09:50:54 +00001876- Issue #7117: Backport round implementation from Python 3.x. ``round()`` now
1877 uses the correctly-rounded string <-> float conversions described above (when
1878 available), and so produces correctly rounded results that will display nicely
1879 under the float repr. There are two related small changes: (1) round now
1880 accepts any class with an ``__index__()`` method for its second argument (but
1881 no longer accepts floats for the second argument), and (2) an excessively
1882 large second integer argument (e.g., ``round(1.234, 10**100)``) no longer
1883 raises an exception.

Georg Brandlba83f822010-03-14 09:50:54 +00002176- Issue #1180193: When importing a module from a .pyc (or .pyo) file with an
2177 existing .py counterpart, override the co_filename attributes of all code

2233
Georg Brandlba83f822010-03-14 09:50:54 +00002234- Issue #4233: Changed semantic of ``_fileio.FileIO``'s ``close()`` method on
2235 file objects with closefd=False. The file descriptor is still kept open but
2236 the file object behaves like a closed file. The ``FileIO`` object also got a

Georg Brandlba83f822010-03-14 09:50:54 +00002260- On windows, ``os.chdir()`` given unicode was not working if
2261 GetCurrentDirectoryW returned a path longer than MAX_PATH. (But It's doubtful
2262 this code path is really executed because I cannot move to such directory on
2263 win2k)

Walter Dörwalded960ac2009-05-03 22:36:33 +00002288- Issue #5108: Handle %s like %S and %R in PyUnicode_FromFormatV(): Call
2289 PyUnicode_DecodeUTF8() once, remember the result and output it in a second

Antoine Pitrou0668c622008-08-26 22:42:08 +00003692 match Python 2.5 speed despite the __instancecheck__ / __subclasscheck__
3693 mechanism. In the process, fix a bug where isinstance() and issubclass(),
3694 when given a tuple of classes as second argument, were looking up
3695 __instancecheck__ / __subclasscheck__ on the tuple rather than on each
3696 type object.
3697
Neal Norwitz18aa3882008-08-24 05:04:52 +00003698- Fix crashes on memory allocation failure found with failmalloc.

3707 function 'stringlib_contains_obj'.
3708
Benjamin Peterson712ee922008-08-24 18:10:20 +00003709- Added warnings on the use of ``__getslice__``, ``__setslice__``, or

Brett Cannon1eaf0742008-09-02 01:25:16 +00003767 warnings.catch_warnings() along with some API cleanup. Expanding the tests
3768 for catch_warnings() also led to an improvement in the raising of a
3769 DeprecationWarning related to warnings.warn_explicit().
3770
Benjamin Peterson973e6c22008-09-01 23:12:58 +00003771- The deprecation warnings for the old camelCase threading API were removed.

Amaury Forgeot d'Arc293924b2008-09-02 23:19:56 +00003794- Issue #2975: When compiling several extension modules with Visual Studio 2008
3795 from the same python interpreter, some environment variables would grow
3796 without limit.
3797
Benjamin Peterson37346b22008-08-23 20:27:43 +00003798- Issue #3643: Added a few more checks to _testcapi to prevent segfaults by

3814 wrapper for warnings.catch_warnings() that makes it easier to check
3815 that expected warning messages are being reported.
3816

Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00003835What's New in Python 2.6 beta 3?
3836================================
3837
Barry Warsaw07a4a382008-08-21 01:15:08 +00003838*Release date: 20-Aug-2008*
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00003839
3840Core and Builtins
3841-----------------
3842
Guido van Rossumf8402962008-08-20 15:01:50 +00003843- Issue #1878: Remove Py_TPFLAGS_HAVE_VERSION_TAG from
3844 Py_TPFLAGS_DEFAULT when not building the core. This means 3rd party
3845 extensions do not automatically benefit from the class attribute
3846 cache; they will have to explicitly add Py_TPFLAGS_HAVE_VERSION_TAG
3847 to their tp_flags field if they care. This is a backwards
3848 compatibility feature; in 3.0, all types will use the cache by
3849 default.
3850
Benjamin Petersonf647dc12008-08-20 01:27:30 +00003851- Keyword arguments can now follow starred arguments. (``f(a, *args,
3852 keyword=23)`` is now valid syntax.)
3853
Thomas Heller0ad5ae02008-08-19 19:25:04 +00003854- ctypes function pointers that are COM methods have a boolean True
3855 value again.
3856
Martin v. Löwisf91d46a2008-08-12 14:49:50 +00003857- Issue #3139: Make buffer-interface thread-safe wrt. PyArg_ParseTuple,
3858 by denying s# to parse objects that have a releasebuffer procedure,
3859 and introducing s*.
3860
Georg Brandl1e13ea92008-08-11 09:07:59 +00003861- Issue #3537: Fix an assertion failure when an empty but presized dict
3862 object was stored in the freelist.
3863
Mark Dickinsonb6467572008-08-04 21:30:09 +00003864- Issue #1481296: Make long(float('nan')) and int(float('nan')) raise
3865 ValueError consistently across platforms.
3866
Amaury Forgeot d'Arc39fd6722008-07-31 21:28:03 +00003867- Issue #3479: On platforms where sizeof(int) is smaller than sizeof(long)
3868 (64bit Unix, for example), unichr() would truncate its argument and return
3869 u'\x00' for unichr(2**32). Now it properly raises an OverflowError.
3870
Neal Norwitze7d8be82008-07-31 17:17:14 +00003871- Apply security patches from Apple.
3872
Amaury Forgeot d'Arc246daed2008-07-31 00:42:16 +00003873- Issue #2542: Now that issubclass() may call arbitrary code, ensure that
3874 PyErr_ExceptionMatches returns 0 when an exception occurs there.
3875
Antoine Pitrou92f82162008-07-25 22:22:08 +00003876- Issue #1819: function calls with several named parameters are now on
3877 average 35% faster (as measured by pybench).
3878
Amaury Forgeot d'Arce4921fe2008-07-21 22:00:38 +00003879- Issue #2378: An unexpected UnboundLocalError or NameError could appear when
3880 the python debugger steps into a class statement: the free variables (local
3881 variables defined in an outer scope) would be deleted from the outer scope.
3882
Gregory P. Smith0470bab2008-07-22 04:46:32 +00003883- Issue #2620: Overflow checking when allocating or reallocating memory
3884 was not always being done properly in some python types and extension
3885 modules. PyMem_MALLOC, PyMem_REALLOC, PyMem_NEW and PyMem_RESIZE have
3886 all been updated to perform better checks and places in the code that
3887 would previously leak memory on the error path when such an allocation
3888 failed have been fixed.

3891-------
3892
Hirokazu Yamamoto838c79f2008-08-20 13:14:07 +00003893- Issue #3612: Added some missing basic types in ctypes.wintypes.
3894
Benjamin Petersone977ad42008-08-20 01:42:01 +00003895- The methods ``is_in_tuple()``, ``is_vararg()``, and ``is_keywordarg()`` of
3896 symtable.Symbol have been deprecated for removal in 3.0 and the next release.
3897
Amaury Forgeot d'Arc351ffb82008-08-18 19:23:47 +00003898- Issue #2234: distutils failed for some versions of the cygwin compiler. The
3899 version reported by these tools does not necessarily follow the python
3900 version numbering scheme, so the module is less strict when parsing it.
3901
Nick Coghlanf70385a2008-08-18 12:42:46 +00003902- Issue #2235: Added Py3k warnings for types which will become unhashable
3903 under the stricter __hash__ inheritance rules in 3.0. Several types
3904 which did not meet the rules for hash invariants and were already
3905 unhashable in 3.0 have now been explicitly flagged as unhashable in
3906 2.6 as well (collections.Mapping, collections.Set, unittest.TestSuite,
3907 xml.dom.minidom.NamedNodeMap, numbers.Number, UserList.UserList)
3908
Brett Cannon88f801d2008-08-18 00:46:22 +00003909- Update __all__ for cookielib, csv, os, urllib2, and weakref to include things
3910 imported into the module but exposed as part of the module's API.
3911
Brett Cannon7b96f072008-08-18 00:41:11 +00003912- Remove an unneeded import of abc.ABCMeta from 'inspect'.

3917
Hirokazu Yamamoto41a81eb2008-08-17 13:10:46 +00003918- Issue #3575: Incremental decoder's decode function now takes bytearray
3919 by using 's*' instead of 't#'.
3920
Mark Dickinson3e4caeb2009-02-21 20:27:01 +00003921- Issue #2222: Fixed reference leak when occurred os.rename()
Hirokazu Yamamoto7f30a682008-08-17 09:46:56 +00003922 fails unicode conversion on 2nd parameter. (windows only)
3923
Georg Brandl222e2082010-08-01 22:27:39 +00003924- Issue #2464: urllib2 now supports a malformation in the URL received
Facundo Batista94f243a2008-08-17 03:38:39 +00003925 in a redirect.
3926
Brett Cannonabe423e2008-08-16 21:47:07 +00003927- Silence the DeprecationWarning raised when importing mimetools in
Brett Cannon721b1452008-08-16 22:00:27 +00003928 BaseHTTPServer, cgi (and rfc822), httplib.
Brett Cannonabe423e2008-08-16 21:47:07 +00003929
Facundo Batistaeb90b782008-08-16 14:44:07 +00003930- Issue #2776: fixed small issue when handling an URL with double slash
3931 after a 302 response in the case of not going through a proxy.
3932
Antoine Pitroub90a8be2008-08-15 21:03:21 +00003933- Issue #2676: in the email package, content-type parsing was hanging on
3934 pathological input because of quadratic or exponential behaviour of a
3935 regular expression.
3936
Antoine Pitrou11ec65d2008-08-14 21:04:30 +00003937- Issue #3476: binary buffered reading through the new "io" library is now
3938 thread-safe.
3939
Brett Cannonbf3157b2008-08-14 05:00:03 +00003940- Silence the DeprecationWarning of rfc822 when it is imported by mimetools
3941 since mimetools itself is deprecated. Because modules are cached, all
3942 subsequent imports of rfc822 will not raise a visible DeprecationWarning.
3943
Antoine Pitrou9fcd4b32008-08-11 17:21:36 +00003944- Issue #3134: shutil referenced undefined WindowsError symbol.
3945
Robert Schuppenies14646332008-08-10 11:01:53 +00003946- Issue #1342811: Fix leak in Tkinter.Menu.delete. Commands associated to
3947 menu entries were not deleted.
3948
Brett Cannon83e81842008-08-09 23:30:55 +00003949- Copied the implementation of reduce() to _functools.reduce() to have a
3950 version that did not raise a DeprecationWarning under -3.
3951
Antoine Pitrou76b8bee2008-08-09 17:27:23 +00003952- Issue #3205: When iterating over a BZ2File fails allocating memory, raise
3953 a MemoryError rather than silently stop the iteration.
3954
Guido van Rossum59ce9012008-08-09 14:55:34 +00003955- Issue #3487: sre "bytecode" validator. Passing invalid "re-bytecode"
3956 to _sre.compile() will now be rejected. This should not affect anybody
3957 since the re.compile() function never generates invalid re-bytecode.
3958
Skip Montanaroa032bf42008-08-08 22:52:51 +00003959- Issue #3436: Make csv.DictReader's fieldnames attribute a property so that
3960 upon first access it can be automatically initialized from the csv file if
3961 it wasn't initialized during instantiation.
3962
Brett Cannon3aa2a492008-08-06 22:28:09 +00003963- Issue #2338: Create imp.reload() to help with transitioning to Python 3.0 as
3964 the reload() built-in has been removed.
3965
Brett Cannon7e30b672008-08-04 21:52:25 +00003966- Changed code in the following modules/packages to remove warnings raised
Brett Cannonc1b76e42008-08-09 23:06:16 +00003967 while running under the ``-3`` flag: aifc, asynchat, asyncore, bdb, bsddb,

4035-----------------
4036
Georg Brandl3e483f62008-07-16 22:57:41 +00004037- Issue #3156: Fix inconsistent behavior of the bytearray type: all
4038 its methods now allow for items objects that can be converted to
4039 an integer using operator.index().
4040
Mark Dickinson64b7e502008-07-16 09:40:03 +00004041- Issue #3360: Fix incorrect parsing of '020000000000.0', which
4042 produced a ValueError instead of giving the correct float.
4043
Eric Smitha5fa5a22008-07-16 00:11:49 +00004044- Issue #3083: Add alternate (#) formatting for bin, oct, hex output
4045 for str.format(). This adds the prefix 0b, 0o, or 0x, respectively.
4046
Mark Dickinson7103aa42008-07-15 19:08:33 +00004047- Issue #3008: the float type has a new instance method 'float.hex'
4048 and a new class method 'float.fromhex' to convert floating-point
4049 numbers to and from hexadecimal strings, respectively.
4050
Nick Coghlan6d6bd442008-07-15 15:40:22 +00004051- Issue #2235: __hash__ is once again inherited by default. To allow
4052 collections.Hashable to remain meaningful in the presence of the
4053 default hash implementation (object.__hash__), it is now possible
4054 to explicit block inheritance of hash by setting __hash__=None at
4055 the Python level, or tp_hash=PyObject_HashNotImplemented at the C
4056 level.
4057
Nick Coghlanb028f502008-07-13 14:52:36 +00004058- Issue #3221: Issue a RuntimeWarning instead of raising SystemError if
4059 the parent module cannot be found while performing an absolute import.
4060 This means that an incorrectly defined __package__ attribute will
4061 now only prevent relative imports in that module rather than causing
4062 all imports from that module to fail.
4063
Nick Coghlan14ff9942008-07-08 14:21:42 +00004064- Issue #2517: Allow unicode messages in Exceptions again by correctly

4074 another thread's dictionary.
4075
Mark Dickinson1ec2fcd2008-06-20 14:53:43 +00004076- Issue #3004: Minor change to slice.indices(): the start and stop
4077 arguments are now treated identically, making the behaviour easier
4078 to describe and understand. For example, slice(None, -10,
4079 1).indices(9) now returns (0, 0, 1) instead of (0, -1, 1), and
4080 slice(None, 10, -1).indices(10) returns (9, 9, -1) instead of (9,
4081 10, -1).

Georg Brandl278fc502008-07-19 12:46:12 +00004083- Issue #3219: Calling a function with repeated keyword arguments,

4124 both unnecessary (HTTP allows text content to be sent in several forms) and
Andrew M. Kuchlingcc3f2b12008-07-10 14:43:31 +00004125 wrong because the actual transmitted size could differ from the
Amaury Forgeot d'Arc0f7cddc2008-07-06 21:34:39 +00004126 content-length. The problem had been corrected in the 2.4 branch, but never

Georg Brandl74a1dea2008-05-28 11:21:39 +00004553- Add ``PyType_Modified()`` as a public API to clear the type cache.
4554
4555- The PyBytes functions have been renamed to PyByteArray.
Christian Heimes7a990612008-05-26 13:15:11 +00004556
4557- The PyString functions have been renamed to PyBytes. A batch of
4558 defines were added so that the linker still sees the original
4559 PyString names.

Georg Brandl3ee81df2008-05-17 18:14:43 +00004597- Issue #1631171: Re-implement the 'warnings' module in C (the
4598 original Python code has been kept as backup). This will allow for
4599 using the 'warning's machinery in such places as the parser where
4600 use of pure Python code is not possible. Both the ``showarning()``
4601 and ``formatwarning()`` gain an optional 'line' argument which is
4602 not called by default for backwards-compatibility reasons. Setting
4603 ``warnings.showwarning()`` to an implementation that lacks support
4604 for the ``line`` argument will raise a DeprecationWarning.

Georg Brandl3ee81df2008-05-17 18:14:43 +00004646- Issue #2513: distutils on Windows is now capable of cross-compiling
Mark Hammond495cf992008-04-07 01:53:39 +00004647 extension modules between 32 and 64 bit platforms. See the distutls

4651 threads at once without fear of crashing the Python interpreter. If
4652 file.close() is called while an object is in use by another thread
4653 an IOError exception will be raised and the file will not be closed.
4654
Thomas Hellerf7906482008-04-04 19:43:25 +00004655- The bundled libffi copy is now in sync with the recently released

4660 so the controlled environment will more closely mirror the typical
4661 script environment. This supports setup.py scripts that refer to
4662 data files.

Georg Brandl3ee81df2008-05-17 18:14:43 +00004667- Issue #2550: The approach used by client/server code for obtaining
4668 ports to listen on in network-oriented tests has been refined in an
4669 effort to facilitate running multiple instances of the entire
4670 regression test suite in parallel without issue.
4671 test_support.bind_port() has been fixed such that it will always
4672 return a unique port -- which wasn't always the case with the
4673 previous implementation, especially if socket options had been set
4674 that affected address reuse (i.e. SO_REUSEADDR, SO_REUSEPORT). The
4675 new implementation of bind_port() will actually raise an exception
4676 if it is passed an AF_INET/SOCK_STREAM socket with either the
4677 SO_REUSEADDR or SO_REUSEPORT socket option set. Furthermore, if
4678 available, bind_port() will set the SO_EXCLUSIVEADDRUSE option on
4679 the socket it's been passed. This currently only applies to
4680 Windows. This option prevents any other sockets from binding to the
4681 host/port we've bound to, thus removing the possibility of the
4682 'non-deterministic' behaviour, as Microsoft puts it, that occurs
4683 when a second SOCK_STREAM socket binds and accepts to a host/port
4684 that's already been bound by another socket. The optional preferred
4685 port parameter to bind_port() has been removed. Under no
4686 circumstances should tests be hard coding ports!
4687
4688 test_support.find_unused_port() has also been introduced, which will
4689 pass a temporary socket object to bind_port() in order to obtain an
4690 unused port. The temporary socket object is then closed and
4691 deleted, and the port is returned. This method should only be used
4692 for obtaining an unused port in order to pass to an external program
4693 (i.e. the -accept [port] argument to openssl's s_server mode) or as
4694 a parameter to a server-oriented class that doesn't give you direct
4695 access to the underlying socket used.
4696
4697 Finally, test_support.HOST has been introduced, which should be used
4698 for the host argument of any relevant socket calls (i.e. bind and
4699 connect).
Trent Nelsone41b0062008-04-08 23:47:30 +00004700
4701 The following tests were updated to following the new conventions:
Georg Brandl3ee81df2008-05-17 18:14:43 +00004702 test_socket, test_smtplib, test_asyncore, test_ssl, test_httplib,
Trent Nelsone41b0062008-04-08 23:47:30 +00004703 test_poplib, test_ftplib, test_telnetlib, test_socketserver,
4704 test_asynchat and test_socket_ssl.
4705
Georg Brandl3ee81df2008-05-17 18:14:43 +00004706 It is now possible for multiple instances of the regression test
4707 suite to run in parallel without issue.

Eric Smitha73fbe72008-02-23 03:09:44 +00004986- Added the future_builtins module, which contains hex() and oct().
4987 These are the PEP 3127 version of these functions, designed to be
4988 compatible with the hex() and oct() builtins from Python 3.0. They
4989 differ slightly in their output formats from the existing, unchanged
4990 Python 2.6 builtins. The expected usage of the future_builtins
4991 module is:
4992 from future_builtins import hex, oct
4993
Eric Smith7ef40bf2008-02-20 23:34:22 +00004994- Issue #1600: Modifed PyOS_ascii_formatd to use at most 2 digit
4995 exponents for exponents with absolute value < 100. Follows C99
4996 standard. This is a change on Windows, which would use 3 digits.
4997 Also, added 'n' to the formats that PyOS_ascii_formatd understands,
4998 so that any alterations it does to the resulting string will be
4999 available in stringlib/formatter.h (for float.__format__).
5000
Eric Smith5a3c1352008-02-19 13:21:56 +00005001- Implemented PEP 3101, Advanced String Formatting. This adds a new
5002 builtin format(); a format() method for str and unicode; a
5003 __format__() method to object, str, unicode, int, long, float, and
5004 datetime; the class string.Formatter; and the C API
5005 PyObject_Format().
5006
Georg Brandl3ee81df2008-05-17 18:14:43 +00005007- Fixed several potential crashes, all caused by specially crafted
5008 __del__ methods exploiting objects in temporarily inconsistent
5009 state.
Amaury Forgeot d'Arc632fad32008-02-16 20:55:24 +00005010
Vinay Sajipb7edfc42008-04-02 21:10:23 +00005011- Issue #2115: Important speedup in setting __slot__ attributes. Also
Georg Brandl3ee81df2008-05-17 18:14:43 +00005012 prevent a possible crash: an Abstract Base Class would try to access
5013 a slot on a registered virtual subclass.

Georg Brandl3ee81df2008-05-17 18:14:43 +00005018- Clear all free lists during a gc.collect() of the highest generation
5019 in order to allow pymalloc to free more arenas. Python may give back
5020 memory to the OS earlier.
Christian Heimes3b718a72008-02-14 12:47:33 +00005021
Georg Brandl3ee81df2008-05-17 18:14:43 +00005022- Issue #2045: Fix an infinite recursion triggered when printing a
5023 subclass of collections.defaultdict, if its default_factory is set
5024 to a bound method.
Amaury Forgeot d'Arcb01aa432008-02-08 00:56:02 +00005025
Christian Heimesf75dbef2008-02-08 00:11:31 +00005026- Fixed a minor memory leak in dictobject.c. The content of the free
5027 list was not freed on interpreter shutdown.
5028
Georg Brandl21e99f42010-03-07 15:23:59 +00005029- Limit free list of method and built-in function objects to 256

Georg Brandl3ee81df2008-05-17 18:14:43 +00005032- Patch #1953: Added ``sys._compact_freelists()`` and the C API
5033 functions ``PyInt_CompactFreeList`` and ``PyFloat_CompactFreeList``
Christian Heimes422051a2008-02-04 18:00:12 +00005034 to compact the internal free lists of pre-allocted ints and floats.
5035
Georg Brandl3ee81df2008-05-17 18:14:43 +00005036- Issue #1983: Fixed return type of fork(), fork1() and forkpty()
5037 calls. Python expected the return type int but the fork familie
5038 returns pi_t.
Christian Heimes951cc0f2008-01-31 23:08:23 +00005039

Georg Brandl3ee81df2008-05-17 18:14:43 +00005052- Patch #1473257: generator objects gain a gi_code attribute. This is
5053 the same object as the func_code attribute of the function that
5054 produced the generator.
Georg Brandl0cdf9a32008-01-26 14:14:20 +00005055
Georg Brandl3ee81df2008-05-17 18:14:43 +00005056- Issue #1920: "while 0" statements were completely removed by the
5057 compiler, even in the presence of an "else" clause, which is

5059 correctly emits bytecode for the "else" suite.

5063 borrowed_ref_[34].py (not in tracker).
5064
Vinay Sajipd7cf32e2008-01-24 12:43:33 +00005065- Issue #1069410: The "can't load dll" message box on Windows is
Christian Heimesb2302ba2008-01-23 17:15:06 +00005066 suppressed while an extension is loaded by calling SetErrorMode in
5067 dynload_win.c. The error is still reported properly.
5068
Georg Brandl3ee81df2008-05-17 18:14:43 +00005069- Issue #1915: Python compiles with --enable-unicode=no again. However
Christian Heimes082c9b02008-01-23 14:20:50 +00005070 several extension methods and modules do not work without unicode
5071 support.
5072
Georg Brandl26543b12008-01-21 18:36:51 +00005073- Issue #1882: when compiling code from a string, encoding cookies in the
5074 second line of code were not always recognized correctly.
5075
Georg Brandl14404b62008-01-19 19:27:05 +00005076- Issue #1679: "0x" was taken as a valid integer literal.
5077
Georg Brandl6caad7d2008-01-26 14:19:22 +00005078- Issue #1865: ``bytes`` as an alias for ``str`` and b"" as an alias "" were
Christian Heimes288e89a2008-01-18 18:24:07 +00005079 added.
5080
Christian Heimesc94e2b52008-01-14 04:13:37 +00005081- sys.float_info / PyFloat_GetInfo: The floating point information
5082 object was converted from a dict to a specialized structseq object.
5083
Georg Brandl3ee81df2008-05-17 18:14:43 +00005084- Patch #1816: Added sys.flags structseq. It exposes the status of
5085 most command line arguments and PYTHON* environment variables.
Christian Heimesf31b69f2008-01-14 03:42:48 +00005086
Georg Brandl3ee81df2008-05-17 18:14:43 +00005087- Objects/structseq.c: Implemented new structseq representation. The
5088 patch makes structseqs (e.g. the return value of os.stat) more
5089 readable.
Christian Heimes9c201962008-01-14 03:33:52 +00005090
Georg Brandl3ee81df2008-05-17 18:14:43 +00005091- Patch #1700288: added a type attribute cache that caches method
5092 accesses, resulting in speedups in heavily object-oriented code.
Amaury Forgeot d'Arce4c270c2008-01-14 00:29:41 +00005093
Neal Norwitz3fc15b82008-01-10 05:42:58 +00005094- Bug #1776: __import__() no longer accepts filenames on any platform.
5095 The first parameter to __import__() must be a valid module name.
Christian Heimes3403f152008-01-09 19:56:33 +00005096
Georg Brandlaed6c662008-01-07 17:25:53 +00005097- Patch #1668: renamed THREADDEBUG envvar to PYTHONTHREADDEBUG.
5098
Georg Brandl3ee81df2008-05-17 18:14:43 +00005099- Patch #602345: Add -B command line option, PYTHONDONTWRITEBYTECODE
5100 envvar and sys.dont_write_bytecode attribute. All these can be set
5101 to forbid Python to attempt to write compiled bytecode files.
Georg Brandl2da0fce2008-01-07 17:09:35 +00005102
Georg Brandl3ee81df2008-05-17 18:14:43 +00005103- Improve some exception messages when Windows fails to load an
5104 extension module. Now we get for example '%1 is not a valid Win32
5105 application' instead of 'error code 193'.
Amaury Forgeot d'Arce0b76952008-01-04 02:04:15 +00005106
Georg Brandl3ee81df2008-05-17 18:14:43 +00005107- Bug #1481296: Fixed long(float('nan')) != 0L.

Georg Brandl3ee81df2008-05-17 18:14:43 +00005109- Issue #1640: Added math.isinf(x), math.isnan(x) and math.copysign(x,
5110 y) functions.
Christian Heimese2ca4242008-01-03 20:23:15 +00005111
Christian Heimes0a8143f2007-12-18 23:22:54 +00005112- Issue #1635: Platform independent creation and representation of NaN
Georg Brandl3ee81df2008-05-17 18:14:43 +00005113 and INF. float("nan"), float("inf") and float("-inf") now work on
5114 every platform with IEEE 754 semantics.
Christian Heimes0a8143f2007-12-18 23:22:54 +00005115
Georg Brandl3ee81df2008-05-17 18:14:43 +00005116- Compiler now generates simpler and faster code for dictionary
5117 literals. The oparg for BUILD_MAP now indicates an estimated
5118 dictionary size. There is a new opcode, STORE_MAP, for adding
5119 entries to the dictionary.

Georg Brandl3ee81df2008-05-17 18:14:43 +00005148- Patch #1739468: Directories and zipfiles containing a __main__.py
5149 file can now be directly executed by passing their name to the
5150 interpreter. The directory/zipfile is automatically inserted as the
5151 first entry in sys.path.
Nick Coghlan327a39b2007-11-18 11:56:28 +00005152
Georg Brandl3ee81df2008-05-17 18:14:43 +00005153- Issue #1265: Fix a problem with sys.settrace, if the tracing
5154 function uses a generator expression when at the same time the
5155 executed code is closing a paused generator.
Amaury Forgeot d'Arc0d75f092007-11-13 21:54:28 +00005156
Raymond Hettinger1760c8a2007-11-08 02:52:43 +00005157- sets and frozensets now have an isdisjoint() method.
5158
Raymond Hettinger3f8caa32007-10-24 01:28:33 +00005159- optimize the performance of builtin.sum().
5160
Neal Norwitz44f326e2007-10-05 05:29:17 +00005161- Fix warnings found by the new version of the Coverity checker.
5162
Georg Brandl21e99f42010-03-07 15:23:59 +00005163- The enumerate() built-in function is no longer bounded to sequences
Georg Brandl3ee81df2008-05-17 18:14:43 +00005164 smaller than LONG_MAX. Formerly, it raised an OverflowError. Now,
5165 automatically shifts from ints to longs.
Raymond Hettinger8f669372007-10-03 21:18:11 +00005166
Georg Brandl3ee81df2008-05-17 18:14:43 +00005167- Issue #1686386: Tuple's tp_repr did not take into account the
5168 possibility of having a self-referential tuple, which is possible
5169 from C code. Nor did object's tp_str consider that a type's tp_str
5170 could do something that could lead to an inifinite recursion.
5171 Py_ReprEnter() and Py_EnterRecursiveCall(), respectively, fixed the
5172 issues.
Brett Cannon0b14f242007-09-30 19:45:10 +00005173
Georg Brandl3ee81df2008-05-17 18:14:43 +00005174- Issue #1164: It was possible to trigger deadlock when using the
5175 'print' statement to write to a file since the GIL was not released
5176 as needed. Now PyObject_Print() does the right thing along with
5177 various tp_print implementations of the built-in types and those in
5178 the collections module.
Brett Cannon01531592007-09-17 03:28:34 +00005179
Georg Brandl3ee81df2008-05-17 18:14:43 +00005180- Issue #1147: Exceptions were directly allowing string exceptions in
5181 their throw() method even though string exceptions no longer
5182 allowed.
Brett Cannon4c20bc42007-09-11 21:02:28 +00005183
Georg Brandl3ee81df2008-05-17 18:14:43 +00005184- Issue #1096: Prevent a segfault from getting the repr of a very
5185 deeply nested list by using the recursion counter.
Brett Cannona0c05512007-09-10 21:38:27 +00005186
Brett Cannon1e534b52007-09-07 04:18:30 +00005187- Issue #1202533: Fix infinite recursion calls triggered by calls to
Georg Brandl3ee81df2008-05-17 18:14:43 +00005188 PyObject_Call() never calling back out to Python code to trigger
5189 recursion depth updates/checks. Required the creation of a static
5190 RuntimeError instance in case normalizing an exception put the
5191 recursion check value past its limit. Fixes crashers
5192 infinite_rec_(1|2|4|5).py.
Brett Cannon1e534b52007-09-07 04:18:30 +00005193
Georg Brandl3ee81df2008-05-17 18:14:43 +00005194- Patch #1031213: Decode source line in SyntaxErrors back to its

Neal Norwitz0ac60192007-05-27 04:08:54 +00005207- Add new attribute names for function objects. All the func_* become
Georg Brandl3ee81df2008-05-17 18:14:43 +00005208 __*__ attributes. (Some already existed, e.g., __doc__ and
5209 __name__.)
Neal Norwitz0ac60192007-05-27 04:08:54 +00005210
Neal Norwitz8b2bfbc2007-05-23 06:35:32 +00005211- Add -3 option to the interpreter to warn about features that are
5212 deprecated and will be changed/removed in Python 3.0.
5213
Georg Brandl2134e752007-05-21 20:34:16 +00005214- Patch #1686487: you can now pass any mapping after '**' in function
5215 calls.
5216
Collin Winter62903052007-05-18 23:11:24 +00005217- except clauses may now be spelled either "except E, target:" or
Georg Brandl3ee81df2008-05-17 18:14:43 +00005218 "except E as target:". This is to provide forwards compatibility
5219 with Python 3.0.
Collin Winter62903052007-05-18 23:11:24 +00005220
Brett Cannon229cee22007-05-05 01:34:02 +00005221- Deprecate BaseException.message as per PEP 352.
5222
Georg Brandl3ee81df2008-05-17 18:14:43 +00005223- Issue #1303614: don't expose object's __dict__ when the dict is
Georg Brandl21e99f42010-03-07 15:23:59 +00005224 inherited from a built-in base.
Armin Rigo9790a272007-05-02 19:23:31 +00005225
Vinay Sajip8549ce32007-05-06 17:53:37 +00005226- When __slots__ are set to a unicode string, make it work the same as
Neal Norwitzcbd9ee62007-04-14 05:25:50 +00005227 setting a plain string, ie don't expand to single letter identifiers.
5228
Raymond Hettinger13936692007-04-11 18:40:58 +00005229- Request #1191699: Slices can now be pickled.
5230
Raymond Hettinger4db5fe92007-04-12 04:10:00 +00005231- Request #1193128: str.translate() now allows a None argument for
5232 translations that only remove characters without re-mapping the
5233 remaining characters.
5234
Georg Brandl5cb76c12007-03-21 09:00:39 +00005235- Patch #1682205: a TypeError while unpacking an iterable is no longer
5236 masked by a generic one with the message "unpack non-sequence".
5237
Neal Norwitzaa754b72007-03-21 06:39:48 +00005238- Remove unused file Python/fmod.c.
5239
Guido van Rossum143b5642007-03-23 04:58:42 +00005240- Bug #1683368: The object.__init__() and object.__new__() methods are
5241 now stricter in rejecting excess arguments. The only time when
5242 either allows excess arguments is when it is not overridden and the
5243 other one is. For backwards compatibility, when both are
5244 overridden, it is a deprecation warning (for now; maybe a Py3k
Guido van Rossum234b1ff2007-03-23 19:39:01 +00005245 warning later). Also, type.__init__() insists on the same signature
5246 as supported by type.__new__().
Guido van Rossum143b5642007-03-23 04:58:42 +00005247
Georg Brandl3ee81df2008-05-17 18:14:43 +00005248- Patch #1675423: PyComplex_AsCComplex() now tries to convert an
5249 object to complex using its __complex__() method before falling back
5250 to the __float__() method. Therefore, the functions in the cmath
5251 module now can operate on objects that define a __complex__()
5252 method.
Georg Brandl2b869942007-03-17 16:08:45 +00005253
Georg Brandl3ee81df2008-05-17 18:14:43 +00005254- Patch #1623563: allow __class__ assignment for classes with
5255 __slots__. The old and the new class are still required to have the
5256 same slot names.
Žiga Seilnacht6f2d09c2007-03-16 11:59:38 +00005257
Georg Brandl3ee81df2008-05-17 18:14:43 +00005258- Patch #1642547: Fix an error/crash when encountering syntax errors

Georg Brandl3ee81df2008-05-17 18:14:43 +00005261- Patch #1462488: Python no longer segfaults when
5262 ``object.__reduce_ex__()`` is called with an object that is faking
5263 its type.
Žiga Seilnacht20f43d32007-03-15 11:44:55 +00005264
Georg Brandl3ee81df2008-05-17 18:14:43 +00005265- Patch #1680015: Don't modify __slots__ tuple if it contains an

5269
Georg Brandl7b9c5552007-03-12 14:30:05 +00005270- Bug #1678647: write a newline after printing an exception in any
5271 case, even when converting the value to a string failed.
5272
Georg Brandl871f1bc2007-03-12 13:17:36 +00005273- The dir() function has been extended to call the __dir__() method on
Georg Brandl3ee81df2008-05-17 18:14:43 +00005274 its argument, if it exists. If not, it will work like before. This
5275 allows customizing the output of dir() in the presence of a
5276 __getattr__().
Georg Brandl871f1bc2007-03-12 13:17:36 +00005277
Collin Winter276887b2007-03-12 16:11:39 +00005278- Patch #922167: Python no longer segfaults when faced with infinitely
5279 self-recursive reload() calls (as reported by bug #742342).
5280
Georg Brandl3ee81df2008-05-17 18:14:43 +00005281- Patch #1675981: remove unreachable code from ``type.__new__()``

Georg Brandl3ee81df2008-05-17 18:14:43 +00005284- Patch #1491866: change the complex() constructor to allow
5285 parthensized forms. This means complex(repr(x)) now works instead of
5286 raising a ValueError.
Collin Wintere38051d2007-03-09 20:33:07 +00005287
Georg Brandlaa2321b2007-03-07 00:40:28 +00005288- Patch #703779: unset __file__ in __main__ after running a file. This
Georg Brandl3ee81df2008-05-17 18:14:43 +00005289 makes the filenames the warning module prints much more sensible
5290 when a PYTHONSTARTUP file is used.
Georg Brandlaa2321b2007-03-07 00:40:28 +00005291
Georg Brandl49aafc92007-03-07 00:34:46 +00005292- Variant of patch #697613: don't exit the interpreter on a SystemExit
5293 exception if the -i command line option or PYTHONINSPECT environment
Georg Brandl3ee81df2008-05-17 18:14:43 +00005294 variable is given, but break into the interactive interpreter just
5295 like on other exceptions or normal program exit.

5797 ".cpp" too.
5798
Facundo Batistad918a652007-04-24 13:54:38 +00005799- As specified in RFC 2616, an HTTP response like 2xx indicates that
Georg Brandl3ee81df2008-05-17 18:14:43 +00005800 the client's request was successfully received, understood, and
5801 accepted. Now in these cases no error is raised in urllib (issue
5802 #1177) and urllib2.
Facundo Batistad918a652007-04-24 13:54:38 +00005803

Facundo Batistab6a5c9d2007-03-29 18:22:35 +00005810- Added a timeout parameter to the constructor of other protocols
5811 (telnetlib, ftplib, smtplib and poplib). This is second part of the
5812 work started with create_connection() and timeout in httplib, and
5813 closes patch #723312.
5814
Vinay Sajip8549ce32007-05-06 17:53:37 +00005815- Patch #1676823: Added create_connection() to socket.py, which may be
5816 called with a timeout, and use it from httplib (whose HTTPConnection

Facundo Batista07c78be2007-03-23 18:54:07 +00005818
Martin v. Löwis0af33882007-03-23 13:27:15 +00005819- Bug #978833: Revert r50844, as it broke _socketobject.dup.

5839
Georg Brandlf66b6032007-03-14 08:27:52 +00005840- Bug #767111: fix long-standing bug in urllib which caused an
Georg Brandl3ee81df2008-05-17 18:14:43 +00005841 AttributeError instead of an IOError when the server's response
5842 didn't contain a valid HTTP status line.
Georg Brandlf66b6032007-03-14 08:27:52 +00005843
Georg Brandl3ee81df2008-05-17 18:14:43 +00005844- Patch #957650: "%var%" environment variable references are now
5845 properly expanded in ntpath.expandvars(), also "~user" home

Georg Brandl3ee81df2008-05-17 18:14:43 +00005848- Patch #1429539: pdb now correctly initializes the __main__ module
5849 for the debugged script, which means that imports from __main__ work
Georg Brandlb6ae6aa2007-03-13 21:58:44 +00005850 correctly now.
5851
Georg Brandlbad6f192007-03-13 21:32:56 +00005852- The nonobvious commands.getstatus() function is now deprecated.

5858
Georg Brandl3ee81df2008-05-17 18:14:43 +00005859- Patch #1530482: add pydoc.render_doc() which returns the
5860 documentation for a thing instead of paging it to stdout, which
5861 pydoc.doc() does.

Georg Brandl3ee81df2008-05-17 18:14:43 +00005863- Patch #1533909: the timeit module now accepts callables in addition

5869 parameter which can be set to False to prevent the default
5870 delete-on-close behavior.

Georg Brandl9e6b4702007-03-13 18:15:41 +00005872- Patch #1581073: add a flag to textwrap that prevents the dropping of
5873 whitespace while wrapping.
5874
Georg Brandl92a6bae2007-03-13 17:43:32 +00005875- Patch #1603688: ConfigParser.SafeConfigParser now checks values that
Georg Brandl3ee81df2008-05-17 18:14:43 +00005876 are set for invalid interpolation sequences that would lead to
5877 errors on reading back those values.

5894 with a dictionary containing fields not in the CSV field names list.

Collin Winter22c42ba2007-03-10 02:51:26 +00005912

5920 returned string up to the first NUL character.
5921

5931
Georg Brandl3ee81df2008-05-17 18:14:43 +00005932- unittest now verifies more of its assumptions. In particular,
5933 TestCase and TestSuite subclasses (not instances) are no longer
5934 accepted in TestSuite.addTest(). This should cause no
5935 incompatibility since it never made sense with ordinary subclasses
5936 -- the failure just occurred later, with a more cumbersome
5937 exception.
Georg Brandl9caadf82007-03-08 18:37:31 +00005938

5946 given a unicode argument and os.listdir() returns unicode filenames.
5947
Georg Brandl3ee81df2008-05-17 18:14:43 +00005948- Patch #1673619: setup.py identifies extension modules it doesn't
5949 know how to build and those it knows how to build but that fail to
5950 build.

Georg Brandl3ee81df2008-05-17 18:14:43 +00006326 time so that opening a database previously created with the DB_DUP
6327 or DB_DUPSORT flag set will keep the proper behavior on subsequent
6328 opens. Specifically: dictionary assignment to a DB object will
6329 replace all values for a given key when the database allows
6330 duplicate values. DB users should use DB.put(k, v) when they want
6331 to store duplicates; not DB[k] = v.

6338 characters with ASCII value less than 32. Also, it correctly quotes
6339 dots only if they occur on a single line, as opposed to the previous
6340 behavior of quoting dots if they are the second character of any
6341 line.
