Mark Dickinsona8d26682010-05-04 16:18:25 +000029- Issue #1533: fix inconsistency in range function argument
30 processing: any non-float non-integer argument is now converted to
31 an integer (if possible) using its __int__ method. Previously, only
32 small arguments were treated this way; larger arguments (those whose
33 __int__ was outside the range of a C long) would produce a TypeError.
34
Nick Coghlanc5e44852010-04-28 14:51:08 +000035- Issue #8202: sys.argv[0] is now set to '-m' instead of '-c' when

43 benefit compared to the dynamic memory allocation fallback. Patch by
44 Charles-François Natali.

54 builds on MacOS X. That is, "python setup.py install --user" will install
55 into "~/Library/Python/2.7" instead of "~/.local".

66- Issue #8483: asyncore.dispatcher's __getattr__ method produced confusing
67 error messages when accessing undefined class attributes because of the cheap
68 inheritance with the underlying socket object.
69 The cheap inheritance has been deprecated.

80 ASCII with backslashreplace error handler if str(value) failed
81
Mark Dickinson4f96f5f2010-05-04 14:25:50 +000082- Issue #8567: Fix precedence of signals in Decimal module: when a
83 Decimal operation raises multiple signals and more than one of those
84 signals is trapped, the specification determines the order in which
85 the signals should be handled. In many cases this order wasn't
86 being followed, leading to the wrong Python exception being raised.
87
Antoine Pitrouf7fd8e42010-05-03 16:25:33 +000088- Issue #7865: The close() method of :mod:`io` objects should not swallow

117 suites, the IGNORE_EXCEPTION_DETAIL directive now also ignores the module
Nick Coghlan54677da2010-04-28 14:34:30 +0000118 location of the raised exception. Based on initial patch by Lennart
119 Regebro.
Nick Coghlandfb45df2010-04-28 14:29:06 +0000120
Antoine Pitrou4c7bcf12010-04-27 22:03:37 +0000121- Issue #8086: In :func:`ssl.DER_cert_to_PEM_cert()`, fix missing newline

130 and mappings.
131
Antoine Pitroua6240402010-04-25 21:40:32 +0000132- Issue #2302: Fix a race condition in SocketServer.BaseServer.shutdown,
133 where the method could block indefinitely if called just before the
134 event loop started running. This also fixes the occasional freezes
135 witnessed in test_httpservers.
136
Antoine Pitroufc69af12010-04-24 20:04:58 +0000137- Issue #5103: SSL handshake would ignore the socket timeout and block
138 indefinitely if the other end didn't respond.
139
Antoine Pitrou4d3e3722010-04-24 19:57:01 +0000140- The do_handshake() method of SSL objects now adjusts the blocking mode of
141 the SSL structure if necessary (as other methods already do).

150
Sean Reifscheiderf6ce3cb2010-04-23 08:31:55 +0000151- Issue #8451: Syslog module now uses basename(sys.argv[0]) instead of
152 the string "python" as the *ident*. openlog() arguments are all optional
153 and keywords.
154
Antoine Pitroua5c4b552010-04-22 23:33:02 +0000155- Issue #8108: Fix the unwrap() method of SSL objects when the socket has
156 a non-infinite timeout. Also make that method friendlier with applications
157 wanting to continue using the socket in clear-text mode, by disabling
158 OpenSSL's internal readahead. Thanks to Darryl Miles for guidance.
159
Antoine Pitrouc715a9e2010-04-21 19:28:03 +0000160- Issue #8484: Load all ciphers and digest algorithms when initializing
161 the _ssl extension, such that verification of some SSL certificates

186 filename and date, conforming to the 'standards' they were originally
187 designed to follow. This improves compatibility with patch tools.
188
R. David Murray27ef9372010-04-12 14:26:06 +0000189- Issue #7472: Fixed typo in email.encoders module; messages using ISO-2022
190 character sets will now consistently use a Content-Transfer-Encoding of
191 7bit rather than sometimes being marked as 8bit.

227 (Optimization was unintentionally turned on in gcc --with-pydebug builds in
228 2.7 beta1 as a result of the issue #1628484 fix, combined with autoconf's
229 strange choice of default CFLAGS produced by AC_PROG_CC for gcc.)

268 is called with a non-empty format string. This is an effort to
269 future-proof user code. If a derived class does not currently
270 implement __format__ but later adds its own __format__, it would
271 most likely break user code that had supplied a format string. This

Raymond Hettingera551f312010-04-04 18:34:45 +0000314- the functools module now has a total_ordering() class decorator
Georg Brandl4fabac52010-04-14 08:53:38 +0000315 to simplify the specification of rich comparisons.
Raymond Hettingera551f312010-04-04 18:34:45 +0000316
Raymond Hettingerbb006cf2010-04-04 21:45:01 +0000317- The functools module also adds cmp_to_key() as a tool to transition
Raymond Hettingera551f312010-04-04 18:34:45 +0000318 old-style comparison functions to new-style key-functions.

Mark Dickinson7c63eee2010-04-02 22:27:36 +0000320- Issue #8294: The Fraction constructor now accepts Decimal and float
321 instances directly.
322
Mark Dickinsone096e822010-04-02 10:17:07 +0000323- Issue #7279: Comparisons involving a Decimal signaling NaN now
324 signal InvalidOperation instead of returning False. (Comparisons
Mark Dickinsonf3eeca12010-04-02 10:35:12 +0000325 involving a quiet NaN are unchanged.) Also, Decimal quiet NaNs
326 are now hashable; Decimal signaling NaNs remain unhashable.

329 instances now return a result based on the numeric values of the
330 operands; previously they returned an arbitrary result based on
331 the relative ordering of id(float) and id(Decimal).
332
Barry Warsawf7f2d6f2010-03-31 21:07:16 +0000333- Issue #8233: When run as a script, py_compile.py optionally takes a single
334 argument `-` which tells it to read files to compile from stdin. Each line
335 is read on demand and the named file is compiled immediately. (Original
336 patch by Piotr Ożarowski).

348 True/False. This makes Fraction <=> complex comparisons consistent with
349 int <=> complex, float <=> complex, and complex <=> complex comparisons.

Mark Dickinson4846a8e2010-04-03 14:05:10 +0000448- Issue #8300: When passing a non-integer argument to struct.pack with any
449 integer format code, struct.pack first attempts to convert the non-integer
450 using its __index__ method. If that method is non-existent or raises
451 TypeError it goes on to try the __int__ method, as described below.
452
Georg Brandlba83f822010-03-14 09:50:54 +0000453- Issue #1530559: When passing a non-integer argument to struct.pack with *any*
454 integer format code (one of 'bBhHiIlLqQ'), struct.pack attempts to use the
455 argument's __int__ method to convert to an integer before packing. It also
456 produces a DeprecationWarning in this case. (In Python 2.6, the behaviour
457 was inconsistent: __int__ was used for some integer codes but not for others,
458 and the set of integer codes for which it was used differed between native
459 packing and standard packing.)

Georg Brandlba83f822010-03-14 09:50:54 +0000757 file position when calling `truncate()`. It would previously change the file
758 position to the given argument, which goes against the tradition of
Antoine Pitrouf3fa0742010-01-31 22:26:04 +0000759 ftruncate() and other truncation APIs. Patch by Pascal Chambon.

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

855Core and Builtins
856-----------------
857
Georg Brandlba83f822010-03-14 09:50:54 +0000858- The ``__complex__()`` method is now looked up on the class of instances to
859 make it consistent with other special methods.
Benjamin Petersonecdae192010-01-04 00:43:01 +0000860
Antoine Pitrou5b7139a2010-01-02 21:12:58 +0000861- Issue #7462: Implement the stringlib fast search algorithm for the `rfind`,
862 `rindex`, `rsplit` and `rpartition` methods. Patch by Florent Xicluna.
863
Mark Dickinson1b34d252010-01-01 17:27:30 +0000864- Issue #5080: A number of functions and methods previously produced a
Georg Brandlba83f822010-03-14 09:50:54 +0000865 DeprecationWarning when passed a float argument where an integer was expected.
866 These functions and methods now raise TypeError instead. The majority of the
867 effects of this change are in the extension modules, but some core functions
868 and methods are affected: notably the 'chr', 'range' and 'xrange' builtins,
869 and many unicode/str methods.

880 used to drop the time part of the result.
881
Georg Brandlba83f822010-03-14 09:50:54 +0000882- Issue #1811: Improve accuracy and cross-platform consistency for true division
883 of integers: the result of a/b is now correctly rounded for ints a and b (at
884 least on IEEE 754 platforms), and in particular does not depend on the
885 internal representation of a long.
Mark Dickinson46572832009-12-27 14:55:57 +0000886
Georg Brandlba83f822010-03-14 09:50:54 +0000887- Issue #6108: ``unicode(exception)`` and ``str(exception)`` should return the
888 same message when only ``__str__()`` (and not ``__unicode__()``) is overridden
889 in the subclass.

Ronald Oussoren92919a62009-12-24 13:30:58 +0000892 executables on OSX.
893
Georg Brandlba83f822010-03-14 09:50:54 +0000894 These executables now work properly with the arch(1) command: ``arch -ppc
895 python`` will start a universal binary version of python in PPC mode (unlike
896 previous releases).
Ronald Oussoren92919a62009-12-24 13:30:58 +0000897
Georg Brandlba83f822010-03-14 09:50:54 +0000898- Issue #1680159: Unicode coercion during an 'in' operation no longer masks the

Georg Brandlba83f822010-03-14 09:50:54 +0000919 renaming of `cPickle` to `pickle`. The warning was annoying since there's no

957 the same as passing no argument.
958
Georg Brandlba83f822010-03-14 09:50:54 +0000959- Issue #7348: ``StringIO.StringIO.readline(-1)`` now acts as if it got no

1061 occur include: str for floats and complex numbers; the float and complex
1062 constructors; old-style and new-style numeric formatting; serialization and
1063 deserialization of floats and complex numbers using marshal, pickle and json;
1064 parsing of float and imaginary literals in Python code; Decimal-to-float
1065 conversion.
Mark Dickinsonb678de82009-11-19 18:41:49 +00001066
Georg Brandlba83f822010-03-14 09:50:54 +00001067 The conversions use a Python-adapted version of David Gay's well-known dtoa.c,
1068 providing correctly-rounded strtod and dtoa C functions. This code is
1069 supported on Windows, and on Unix-like platforms using gcc, icc or suncc as
1070 the C compiler. There may be a small number of platforms on which correct
1071 operation of this code cannot be guaranteed, so the code is not used: notably,
1072 this applies to platforms where the C double format is not IEEE 754 binary64,
1073 and to platforms on x86 hardware where the x87 FPU is set to 64-bit precision
1074 and Python's configure script is unable to determine how to change the FPU
1075 precision. On these platforms conversions use the platform strtod and dtoa,
1076 as before.

Georg Brandlba83f822010-03-14 09:50:54 +00001078- Issue #7117: Backport round implementation from Python 3.x. ``round()`` now
1079 uses the correctly-rounded string <-> float conversions described above (when
1080 available), and so produces correctly rounded results that will display nicely
1081 under the float repr. There are two related small changes: (1) round now
1082 accepts any class with an ``__index__()`` method for its second argument (but
1083 no longer accepts floats for the second argument), and (2) an excessively
1084 large second integer argument (e.g., ``round(1.234, 10**100)``) no longer
1085 raises an exception.

1464 this code path is really executed because I cannot move to such directory on
1465 win2k)

1491 PyUnicode_DecodeUTF8() once, remember the result and output it in a second

Georg Brandlba83f822010-03-14 09:50:54 +00002662 - Packing a float now always gives a Deprecation Warning. Previously it

Georg Brandlba83f822010-03-14 09:50:54 +00002665 - If x is not an int, long or float, then packing x will always result in
2666 struct.error. Previously an x with an __int__ method could be packed by
2667 'b', 'B', 'h', 'H', 'i', 'l', '*b', '*h' ,'*i', '*l', and an x with a
2668 __long__ method could be packed by 'q', 'Q', '*q', '*Q'; for x with
2669 neither __int__ nor __long__, TypeError used to be raised (with a
2670 confusing error message) for 'I', 'L', '*B', '*H', '*I', '*L', and
2671 struct.error in other cases.

2674 argument with an __int__ method can be packed, but use of this feature
2675 triggers a DeprecationWarning.

Amaury Forgeot d'Arc05e34492008-09-10 22:04:45 +00002868- Issue #3743: In a few places, PY_FORMAT_SIZE_T was incorrectly used with

2870 PY_FORMAT_SIZE_T is designed to select the correct format for the OS
2871 ``printf`` function, whereas PyString_FromFormat has an independent
2872 implementation and uses "%zd" on all platforms for size_t values.

2969 warnings.catch_warnings() along with some API cleanup. Expanding the tests
2970 for catch_warnings() also led to an improvement in the raising of a
2971 DeprecationWarning related to warnings.warn_explicit().

Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00003037What's New in Python 2.6 beta 3?
3038================================
3039
Barry Warsaw07a4a382008-08-21 01:15:08 +00003040*Release date: 20-Aug-2008*
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00003041
3042Core and Builtins
3043-----------------
3044
Guido van Rossumf8402962008-08-20 15:01:50 +00003045- Issue #1878: Remove Py_TPFLAGS_HAVE_VERSION_TAG from
3046 Py_TPFLAGS_DEFAULT when not building the core. This means 3rd party
3047 extensions do not automatically benefit from the class attribute
3048 cache; they will have to explicitly add Py_TPFLAGS_HAVE_VERSION_TAG
3049 to their tp_flags field if they care. This is a backwards
3050 compatibility feature; in 3.0, all types will use the cache by
3051 default.
3052
Benjamin Petersonf647dc12008-08-20 01:27:30 +00003053- Keyword arguments can now follow starred arguments. (``f(a, *args,
3054 keyword=23)`` is now valid syntax.)
3055
Thomas Heller0ad5ae02008-08-19 19:25:04 +00003056- ctypes function pointers that are COM methods have a boolean True
3057 value again.
3058
Martin v. Löwisf91d46a2008-08-12 14:49:50 +00003059- Issue #3139: Make buffer-interface thread-safe wrt. PyArg_ParseTuple,
3060 by denying s# to parse objects that have a releasebuffer procedure,
3061 and introducing s*.
3062
Georg Brandl1e13ea92008-08-11 09:07:59 +00003063- Issue #3537: Fix an assertion failure when an empty but presized dict
3064 object was stored in the freelist.
3065
Mark Dickinsonb6467572008-08-04 21:30:09 +00003066- Issue #1481296: Make long(float('nan')) and int(float('nan')) raise
3067 ValueError consistently across platforms.
3068
Amaury Forgeot d'Arc39fd6722008-07-31 21:28:03 +00003069- Issue #3479: On platforms where sizeof(int) is smaller than sizeof(long)
3070 (64bit Unix, for example), unichr() would truncate its argument and return
3071 u'\x00' for unichr(2**32). Now it properly raises an OverflowError.
3072
Neal Norwitze7d8be82008-07-31 17:17:14 +00003073- Apply security patches from Apple.
3074
Amaury Forgeot d'Arc246daed2008-07-31 00:42:16 +00003075- Issue #2542: Now that issubclass() may call arbitrary code, ensure that
3076 PyErr_ExceptionMatches returns 0 when an exception occurs there.
3077
Antoine Pitrou92f82162008-07-25 22:22:08 +00003078- Issue #1819: function calls with several named parameters are now on
3079 average 35% faster (as measured by pybench).
3080
Amaury Forgeot d'Arce4921fe2008-07-21 22:00:38 +00003081- Issue #2378: An unexpected UnboundLocalError or NameError could appear when
3082 the python debugger steps into a class statement: the free variables (local
3083 variables defined in an outer scope) would be deleted from the outer scope.
3084
Gregory P. Smith0470bab2008-07-22 04:46:32 +00003085- Issue #2620: Overflow checking when allocating or reallocating memory
3086 was not always being done properly in some python types and extension
3087 modules. PyMem_MALLOC, PyMem_REALLOC, PyMem_NEW and PyMem_RESIZE have
3088 all been updated to perform better checks and places in the code that
3089 would previously leak memory on the error path when such an allocation
3090 failed have been fixed.
3091
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00003092Library
3093-------
3094
Hirokazu Yamamoto838c79f2008-08-20 13:14:07 +00003095- Issue #3612: Added some missing basic types in ctypes.wintypes.
3096
Benjamin Petersone977ad42008-08-20 01:42:01 +00003097- The methods ``is_in_tuple()``, ``is_vararg()``, and ``is_keywordarg()`` of
3098 symtable.Symbol have been deprecated for removal in 3.0 and the next release.
3099
Amaury Forgeot d'Arc351ffb82008-08-18 19:23:47 +00003100- Issue #2234: distutils failed for some versions of the cygwin compiler. The
3101 version reported by these tools does not necessarily follow the python
3102 version numbering scheme, so the module is less strict when parsing it.
3103
Nick Coghlanf70385a2008-08-18 12:42:46 +00003104- Issue #2235: Added Py3k warnings for types which will become unhashable
3105 under the stricter __hash__ inheritance rules in 3.0. Several types
3106 which did not meet the rules for hash invariants and were already
3107 unhashable in 3.0 have now been explicitly flagged as unhashable in
3108 2.6 as well (collections.Mapping, collections.Set, unittest.TestSuite,
3109 xml.dom.minidom.NamedNodeMap, numbers.Number, UserList.UserList)
3110
Brett Cannon88f801d2008-08-18 00:46:22 +00003111- Update __all__ for cookielib, csv, os, urllib2, and weakref to include things
3112 imported into the module but exposed as part of the module's API.
3113
Brett Cannon7b96f072008-08-18 00:41:11 +00003114- Remove an unneeded import of abc.ABCMeta from 'inspect'.
3115
Brett Cannon46225e72008-08-18 00:36:52 +00003116- Remove unneeded imports of 'sys' and 'warnings' from 'io'.

Brett Cannon25c9d6a2008-08-17 22:10:11 +00003118- Remove unneeded imports of 'warnings' from shelve, filecmp, and dummy_thread.
3119
Hirokazu Yamamoto41a81eb2008-08-17 13:10:46 +00003120- Issue #3575: Incremental decoder's decode function now takes bytearray
3121 by using 's*' instead of 't#'.
3122
Mark Dickinson3e4caeb2009-02-21 20:27:01 +00003123- Issue #2222: Fixed reference leak when occurred os.rename()
Hirokazu Yamamoto7f30a682008-08-17 09:46:56 +00003124 fails unicode conversion on 2nd parameter. (windows only)
3125
Facundo Batista94f243a2008-08-17 03:38:39 +00003126- Issue 2464. urllib2 now supports a malformation in the URL received
3127 in a redirect.
3128
Brett Cannonabe423e2008-08-16 21:47:07 +00003129- Silence the DeprecationWarning raised when importing mimetools in
Brett Cannon721b1452008-08-16 22:00:27 +00003130 BaseHTTPServer, cgi (and rfc822), httplib.
Brett Cannonabe423e2008-08-16 21:47:07 +00003131
Facundo Batistaeb90b782008-08-16 14:44:07 +00003132- Issue #2776: fixed small issue when handling an URL with double slash
3133 after a 302 response in the case of not going through a proxy.
3134
Antoine Pitroub90a8be2008-08-15 21:03:21 +00003135- Issue #2676: in the email package, content-type parsing was hanging on
3136 pathological input because of quadratic or exponential behaviour of a
3137 regular expression.
3138
Antoine Pitrou11ec65d2008-08-14 21:04:30 +00003139- Issue #3476: binary buffered reading through the new "io" library is now
3140 thread-safe.
3141
Brett Cannonbf3157b2008-08-14 05:00:03 +00003142- Silence the DeprecationWarning of rfc822 when it is imported by mimetools
3143 since mimetools itself is deprecated. Because modules are cached, all
3144 subsequent imports of rfc822 will not raise a visible DeprecationWarning.
3145
Antoine Pitrou9fcd4b32008-08-11 17:21:36 +00003146- Issue #3134: shutil referenced undefined WindowsError symbol.
3147
Robert Schuppenies14646332008-08-10 11:01:53 +00003148- Issue #1342811: Fix leak in Tkinter.Menu.delete. Commands associated to
3149 menu entries were not deleted.
3150
Brett Cannon83e81842008-08-09 23:30:55 +00003151- Copied the implementation of reduce() to _functools.reduce() to have a
3152 version that did not raise a DeprecationWarning under -3.
3153
Antoine Pitrou76b8bee2008-08-09 17:27:23 +00003154- Issue #3205: When iterating over a BZ2File fails allocating memory, raise
3155 a MemoryError rather than silently stop the iteration.
3156
Guido van Rossum59ce9012008-08-09 14:55:34 +00003157- Issue #3487: sre "bytecode" validator. Passing invalid "re-bytecode"
3158 to _sre.compile() will now be rejected. This should not affect anybody
3159 since the re.compile() function never generates invalid re-bytecode.
3160
Skip Montanaroa032bf42008-08-08 22:52:51 +00003161- Issue #3436: Make csv.DictReader's fieldnames attribute a property so that
3162 upon first access it can be automatically initialized from the csv file if
3163 it wasn't initialized during instantiation.
3164
Brett Cannon3aa2a492008-08-06 22:28:09 +00003165- Issue #2338: Create imp.reload() to help with transitioning to Python 3.0 as
3166 the reload() built-in has been removed.
3167
Brett Cannon7e30b672008-08-04 21:52:25 +00003168- Changed code in the following modules/packages to remove warnings raised
Brett Cannonc1b76e42008-08-09 23:06:16 +00003169 while running under the ``-3`` flag: aifc, asynchat, asyncore, bdb, bsddb,

3172 pstats, pydoc, re, rlcompleter, SimpleXMLRPCServer, shelve, socket,
3173 subprocess, sqlite3, tarfile, Tkinter, test.test_support, textwrap,
3174 threading, tokenize, traceback, urlparse, wsgiref, xml, xmlrpclib.

Antoine Pitroude781a42008-08-09 12:43:23 +00003180 asking for a specific length. This problem only affected files opened
3181 using the new "io" module, not the built-in open() function.
Benjamin Peterson01a24322008-07-28 23:35:27 +00003182

Antoine Pitrou5fdfa3e2008-07-25 19:42:26 +00003206- Issue #3394: zipfile.writestr sets external attributes when passed a
3207 file name rather than a ZipInfo instance, so files are extracted with
3208 mode 0600 rather than 000 under Unix.
3209
Gregory P. Smitha36f8fe2008-08-04 00:13:29 +00003210- Issue #1857: subprocess.Popen.poll gained an additional _deadstate keyword
3211 argument in python 2.5, this broke code that subclassed Popen to include its

3223 interaction with the tp_hash slot (added in 2.6b2) are now documented
3224
Nick Coghlan2a0c2b12008-08-04 12:47:17 +00003225- Issue #643841: The language reference now provides more detailed
3226 coverage of the lookup process for special methods. The disclaimers
3227 regarding lack of coverage of new-style classes have also been
3228 removed, since the coverage is now fairly reasonable.

Raymond Hettingere3ae6552008-06-20 04:18:15 +00003231What's New in Python 2.6 beta 2?
3232================================
3233
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00003234*Release date: 17-Jul-2008*
3235
Raymond Hettingere3ae6552008-06-20 04:18:15 +00003236Core and Builtins
3237-----------------
3238
Georg Brandl3e483f62008-07-16 22:57:41 +00003239- Issue #3156: Fix inconsistent behavior of the bytearray type: all
3240 its methods now allow for items objects that can be converted to
3241 an integer using operator.index().
3242
Mark Dickinson64b7e502008-07-16 09:40:03 +00003243- Issue #3360: Fix incorrect parsing of '020000000000.0', which
3244 produced a ValueError instead of giving the correct float.
3245
Eric Smitha5fa5a22008-07-16 00:11:49 +00003246- Issue #3083: Add alternate (#) formatting for bin, oct, hex output
3247 for str.format(). This adds the prefix 0b, 0o, or 0x, respectively.
3248
Mark Dickinson7103aa42008-07-15 19:08:33 +00003249- Issue #3008: the float type has a new instance method 'float.hex'
3250 and a new class method 'float.fromhex' to convert floating-point
3251 numbers to and from hexadecimal strings, respectively.
3252
Nick Coghlan6d6bd442008-07-15 15:40:22 +00003253- Issue #2235: __hash__ is once again inherited by default. To allow
3254 collections.Hashable to remain meaningful in the presence of the
3255 default hash implementation (object.__hash__), it is now possible
3256 to explicit block inheritance of hash by setting __hash__=None at
3257 the Python level, or tp_hash=PyObject_HashNotImplemented at the C
3258 level.
3259
Nick Coghlanb028f502008-07-13 14:52:36 +00003260- Issue #3221: Issue a RuntimeWarning instead of raising SystemError if
3261 the parent module cannot be found while performing an absolute import.
3262 This means that an incorrectly defined __package__ attribute will
3263 now only prevent relative imports in that module rather than causing
3264 all imports from that module to fail.
3265
Nick Coghlan14ff9942008-07-08 14:21:42 +00003266- Issue #2517: Allow unicode messages in Exceptions again by correctly
3267 bypassing the instance dictionary when looking up __unicode__ on
3268 new-style classes.
3269
Amaury Forgeot d'Arcbdd941f2008-07-01 20:38:04 +00003270- Issue #3242: Fix a crash inside the print statement, if sys.stdout is
3271 set to a custom object whose write() method happens to install
3272 another file in sys.stdout.
3273
Amaury Forgeot d'Arc1f40c8a2008-06-30 22:42:40 +00003274- Issue #3088: Corrected a race condition in classes derived from
3275 threading.local: the first member set by a thread could be saved in
3276 another thread's dictionary.
3277
Mark Dickinson1ec2fcd2008-06-20 14:53:43 +00003278- Issue #3004: Minor change to slice.indices(): the start and stop
3279 arguments are now treated identically, making the behaviour easier
3280 to describe and understand. For example, slice(None, -10,
3281 1).indices(9) now returns (0, 0, 1) instead of (0, -1, 1), and
3282 slice(None, 10, -1).indices(10) returns (9, 9, -1) instead of (9,
3283 10, -1).
3284
Georg Brandl278fc502008-07-19 12:46:12 +00003285- Issue #3219: Calling a function with repeated keyword arguments,
3286 f(a=2, a=23), would not cause a syntax error. This was a regression
3287 from 2.4 caused by the switch to the new compiler.
Benjamin Peterson175e4d92008-07-01 19:34:52 +00003288
Georg Brandl278fc502008-07-19 12:46:12 +00003289- Issue #2862: Make int and float freelist management consistent with
3290 other freelists. Changes their CompactFreeList apis into
3291 ClearFreeList apis and calls them via gc.collect().

Thomas Heller57adf222008-08-14 19:10:48 +00003296- Issue #3554: ctypes.string_at and ctypes.wstring_at did call Python
3297 api functions without holding the GIL, which could lead to a fatal
3298 error when they failed.
3299
Martin v. Löwisaabf4042008-08-02 07:20:25 +00003300- Issue #799428: Fix Tkinter.Misc._nametowidget to unwrap Tcl command objects.

3309 ForkingPickler.register() to resolve conflict with ctypes.
3310
Vinay Sajip51e65192008-07-18 09:01:10 +00003311- Issue #3090: Fixed ARCHFLAGS parsing on OS/X
Jesse Noller13e9d582008-07-16 14:32:36 +00003312
Thomas Heller880f5292008-07-15 19:39:38 +00003313- Issue #3313: Fixed a crash when a failed dlopen() call does not set
3314 a valid dlerror() message.
3315
Thomas Heller2bad6572008-07-15 17:19:50 +00003316- Issue #3258: Fixed a crash when a ctypes POINTER type to an

3322
Andrew M. Kuchlingcc3f2b12008-07-10 14:43:31 +00003323- Issue #3301: Bisect module behaved badly when lo was negative.
Raymond Hettinger3cd1e422008-07-10 14:03:19 +00003324
Amaury Forgeot d'Arc0f7cddc2008-07-06 21:34:39 +00003325- Issue #839496: SimpleHTTPServer used to open text files in text mode. This is
3326 both unnecessary (HTTP allows text content to be sent in several forms) and
Andrew M. Kuchlingcc3f2b12008-07-10 14:43:31 +00003327 wrong because the actual transmitted size could differ from the
Amaury Forgeot d'Arc0f7cddc2008-07-06 21:34:39 +00003328 content-length. The problem had been corrected in the 2.4 branch, but never
3329 merged into trunk.
3330
Georg Brandle78fbcc2008-07-05 10:13:36 +00003331- Issue #2663: add filtering capability to shutil.copytree().

Andrew M. Kuchlingcc3f2b12008-07-10 14:43:31 +00003342 when completed.
Facundo Batista66c52772008-07-02 16:52:55 +00003343
Nick Coghlanc060b0e2008-07-02 13:09:19 +00003344- Issue #3190: Pydoc now hides the automatic module attribute __package__ (the
3345 handling is now the same as that of other special attributes like __name__).
3346
Brett Cannon8bb8fa52008-07-02 01:57:08 +00003347- Issue #2885 (partial): The urllib.urlopen() function has been deprecated for
3348 removal in Python 3.0 in favor of urllib2.urlopen().

3800 original Python code has been kept as backup). This will allow for
3801 using the 'warning's machinery in such places as the parser where
3802 use of pure Python code is not possible. Both the ``showarning()``
3803 and ``formatwarning()`` gain an optional 'line' argument which is
3804 not called by default for backwards-compatibility reasons. Setting
3805 ``warnings.showwarning()`` to an implementation that lacks support
3806 for the ``line`` argument will raise a DeprecationWarning.

Georg Brandl3ee81df2008-05-17 18:14:43 +00003869- Issue #2550: The approach used by client/server code for obtaining
3870 ports to listen on in network-oriented tests has been refined in an
3871 effort to facilitate running multiple instances of the entire
3872 regression test suite in parallel without issue.
3873 test_support.bind_port() has been fixed such that it will always
3874 return a unique port -- which wasn't always the case with the
3875 previous implementation, especially if socket options had been set
3876 that affected address reuse (i.e. SO_REUSEADDR, SO_REUSEPORT). The
3877 new implementation of bind_port() will actually raise an exception
3878 if it is passed an AF_INET/SOCK_STREAM socket with either the
3879 SO_REUSEADDR or SO_REUSEPORT socket option set. Furthermore, if
3880 available, bind_port() will set the SO_EXCLUSIVEADDRUSE option on
3881 the socket it's been passed. This currently only applies to
3882 Windows. This option prevents any other sockets from binding to the
3883 host/port we've bound to, thus removing the possibility of the
3884 'non-deterministic' behaviour, as Microsoft puts it, that occurs
3885 when a second SOCK_STREAM socket binds and accepts to a host/port
3886 that's already been bound by another socket. The optional preferred
3887 port parameter to bind_port() has been removed. Under no
3888 circumstances should tests be hard coding ports!
3889
3890 test_support.find_unused_port() has also been introduced, which will
3891 pass a temporary socket object to bind_port() in order to obtain an
3892 unused port. The temporary socket object is then closed and
3893 deleted, and the port is returned. This method should only be used
3894 for obtaining an unused port in order to pass to an external program
3895 (i.e. the -accept [port] argument to openssl's s_server mode) or as
3896 a parameter to a server-oriented class that doesn't give you direct
3897 access to the underlying socket used.
3898
3899 Finally, test_support.HOST has been introduced, which should be used
3900 for the host argument of any relevant socket calls (i.e. bind and
3901 connect).
Trent Nelsone41b0062008-04-08 23:47:30 +00003902
3903 The following tests were updated to following the new conventions:
Georg Brandl3ee81df2008-05-17 18:14:43 +00003904 test_socket, test_smtplib, test_asyncore, test_ssl, test_httplib,

3906 test_asynchat and test_socket_ssl.
3907
Georg Brandl3ee81df2008-05-17 18:14:43 +00003908 It is now possible for multiple instances of the regression test
3909 suite to run in parallel without issue.

4177
Fred Drakea8ee94b2008-03-01 02:45:07 +00004178- Issue #2051: pyc and pyo files are no longer created with permission
Barry Warsaw52973612008-03-01 02:23:38 +00004179 644. The mode is now inherited from the py file.

4182
4183- Patch #1759: Backport of PEP 3129 class decorators.
Christian Heimes5224d282008-02-23 15:01:05 +00004184
Vinay Sajipb7edfc42008-04-02 21:10:23 +00004185- Issue #1881: An internal parser limit has been increased. Also see
Facundo Batistafc2d0102008-02-23 12:01:13 +00004186 issue 215555 for a discussion.
4187
Eric Smitha73fbe72008-02-23 03:09:44 +00004188- Added the future_builtins module, which contains hex() and oct().
4189 These are the PEP 3127 version of these functions, designed to be
4190 compatible with the hex() and oct() builtins from Python 3.0. They
4191 differ slightly in their output formats from the existing, unchanged
4192 Python 2.6 builtins. The expected usage of the future_builtins
4193 module is:
4194 from future_builtins import hex, oct
4195
Eric Smith7ef40bf2008-02-20 23:34:22 +00004196- Issue #1600: Modifed PyOS_ascii_formatd to use at most 2 digit
4197 exponents for exponents with absolute value < 100. Follows C99
4198 standard. This is a change on Windows, which would use 3 digits.
4199 Also, added 'n' to the formats that PyOS_ascii_formatd understands,
4200 so that any alterations it does to the resulting string will be
4201 available in stringlib/formatter.h (for float.__format__).
4202
Eric Smith5a3c1352008-02-19 13:21:56 +00004203- Implemented PEP 3101, Advanced String Formatting. This adds a new
4204 builtin format(); a format() method for str and unicode; a
4205 __format__() method to object, str, unicode, int, long, float, and
4206 datetime; the class string.Formatter; and the C API
4207 PyObject_Format().
4208
Georg Brandl3ee81df2008-05-17 18:14:43 +00004209- Fixed several potential crashes, all caused by specially crafted
4210 __del__ methods exploiting objects in temporarily inconsistent
4211 state.
Amaury Forgeot d'Arc632fad32008-02-16 20:55:24 +00004212
Vinay Sajipb7edfc42008-04-02 21:10:23 +00004213- Issue #2115: Important speedup in setting __slot__ attributes. Also
Georg Brandl3ee81df2008-05-17 18:14:43 +00004214 prevent a possible crash: an Abstract Base Class would try to access
4215 a slot on a registered virtual subclass.

Georg Brandl3ee81df2008-05-17 18:14:43 +00004220- Clear all free lists during a gc.collect() of the highest generation
4221 in order to allow pymalloc to free more arenas. Python may give back
4222 memory to the OS earlier.
Christian Heimes3b718a72008-02-14 12:47:33 +00004223
Georg Brandl3ee81df2008-05-17 18:14:43 +00004224- Issue #2045: Fix an infinite recursion triggered when printing a
4225 subclass of collections.defaultdict, if its default_factory is set
4226 to a bound method.
Amaury Forgeot d'Arcb01aa432008-02-08 00:56:02 +00004227
Christian Heimesf75dbef2008-02-08 00:11:31 +00004228- Fixed a minor memory leak in dictobject.c. The content of the free
4229 list was not freed on interpreter shutdown.
4230
Georg Brandl21e99f42010-03-07 15:23:59 +00004231- Limit free list of method and built-in function objects to 256

Christian Heimes6075a822008-02-06 12:44:34 +00004233
Georg Brandl3ee81df2008-05-17 18:14:43 +00004234- Patch #1953: Added ``sys._compact_freelists()`` and the C API
4235 functions ``PyInt_CompactFreeList`` and ``PyFloat_CompactFreeList``
Christian Heimes422051a2008-02-04 18:00:12 +00004236 to compact the internal free lists of pre-allocted ints and floats.
4237
Georg Brandl3ee81df2008-05-17 18:14:43 +00004238- Issue #1983: Fixed return type of fork(), fork1() and forkpty()
4239 calls. Python expected the return type int but the fork familie
4240 returns pi_t.
Christian Heimes951cc0f2008-01-31 23:08:23 +00004241

4252 the internal lookup cache for ref leak tests.
Christian Heimes908caac2008-01-27 23:34:59 +00004253
Georg Brandl3ee81df2008-05-17 18:14:43 +00004254- Patch #1473257: generator objects gain a gi_code attribute. This is
4255 the same object as the func_code attribute of the function that
4256 produced the generator.
Georg Brandl0cdf9a32008-01-26 14:14:20 +00004257
Georg Brandl3ee81df2008-05-17 18:14:43 +00004258- Issue #1920: "while 0" statements were completely removed by the
4259 compiler, even in the presence of an "else" clause, which is
4260 supposed to be run when the condition is false. Now the compiler
4261 correctly emits bytecode for the "else" suite.
Amaury Forgeot d'Arc31eaafe2008-01-24 22:59:25 +00004262
Guido van Rossumeead05f2008-01-24 18:21:02 +00004263- A few crashers fixed: weakref_in_del.py (issue #1377858);
4264 loosing_dict_ref.py (issue #1303614, test67.py);
4265 borrowed_ref_[34].py (not in tracker).
4266
Vinay Sajipd7cf32e2008-01-24 12:43:33 +00004267- Issue #1069410: The "can't load dll" message box on Windows is
Christian Heimesb2302ba2008-01-23 17:15:06 +00004268 suppressed while an extension is loaded by calling SetErrorMode in

4270
Georg Brandl3ee81df2008-05-17 18:14:43 +00004271- Issue #1915: Python compiles with --enable-unicode=no again. However
Christian Heimes082c9b02008-01-23 14:20:50 +00004272 several extension methods and modules do not work without unicode
4273 support.
4274
Georg Brandl26543b12008-01-21 18:36:51 +00004275- Issue #1882: when compiling code from a string, encoding cookies in the

4277
Georg Brandl14404b62008-01-19 19:27:05 +00004278- Issue #1679: "0x" was taken as a valid integer literal.
4279
Georg Brandl6caad7d2008-01-26 14:19:22 +00004280- Issue #1865: ``bytes`` as an alias for ``str`` and b"" as an alias "" were
Christian Heimes288e89a2008-01-18 18:24:07 +00004281 added.
4282
Christian Heimesc94e2b52008-01-14 04:13:37 +00004283- sys.float_info / PyFloat_GetInfo: The floating point information
4284 object was converted from a dict to a specialized structseq object.
4285
Georg Brandl3ee81df2008-05-17 18:14:43 +00004286- Patch #1816: Added sys.flags structseq. It exposes the status of
4287 most command line arguments and PYTHON* environment variables.
Christian Heimesf31b69f2008-01-14 03:42:48 +00004288
Georg Brandl3ee81df2008-05-17 18:14:43 +00004289- Objects/structseq.c: Implemented new structseq representation. The

Georg Brandl3ee81df2008-05-17 18:14:43 +00004293- Patch #1700288: added a type attribute cache that caches method
4294 accesses, resulting in speedups in heavily object-oriented code.

Georg Brandlaed6c662008-01-07 17:25:53 +00004299- Patch #1668: renamed THREADDEBUG envvar to PYTHONTHREADDEBUG.
4300
Georg Brandl3ee81df2008-05-17 18:14:43 +00004301- Patch #602345: Add -B command line option, PYTHONDONTWRITEBYTECODE
4302 envvar and sys.dont_write_bytecode attribute. All these can be set
4303 to forbid Python to attempt to write compiled bytecode files.
Georg Brandl2da0fce2008-01-07 17:09:35 +00004304
Georg Brandl3ee81df2008-05-17 18:14:43 +00004305- Improve some exception messages when Windows fails to load an
4306 extension module. Now we get for example '%1 is not a valid Win32
4307 application' instead of 'error code 193'.

Christian Heimes0a8143f2007-12-18 23:22:54 +00004314- Issue #1635: Platform independent creation and representation of NaN
Georg Brandl3ee81df2008-05-17 18:14:43 +00004315 and INF. float("nan"), float("inf") and float("-inf") now work on
4316 every platform with IEEE 754 semantics.

Georg Brandl3ee81df2008-05-17 18:14:43 +00004318- Compiler now generates simpler and faster code for dictionary
4319 literals. The oparg for BUILD_MAP now indicates an estimated
4320 dictionary size. There is a new opcode, STORE_MAP, for adding
4321 entries to the dictionary.

Georg Brandl3ee81df2008-05-17 18:14:43 +00004350- Patch #1739468: Directories and zipfiles containing a __main__.py
4351 file can now be directly executed by passing their name to the
4352 interpreter. The directory/zipfile is automatically inserted as the
4353 first entry in sys.path.

Georg Brandl3ee81df2008-05-17 18:14:43 +00004355- Issue #1265: Fix a problem with sys.settrace, if the tracing
4356 function uses a generator expression when at the same time the
4357 executed code is closing a paused generator.
Amaury Forgeot d'Arc0d75f092007-11-13 21:54:28 +00004358
Raymond Hettinger1760c8a2007-11-08 02:52:43 +00004359- sets and frozensets now have an isdisjoint() method.

4364
Georg Brandl21e99f42010-03-07 15:23:59 +00004365- The enumerate() built-in function is no longer bounded to sequences
Georg Brandl3ee81df2008-05-17 18:14:43 +00004366 smaller than LONG_MAX. Formerly, it raised an OverflowError. Now,
4367 automatically shifts from ints to longs.
Raymond Hettinger8f669372007-10-03 21:18:11 +00004368
Georg Brandl3ee81df2008-05-17 18:14:43 +00004369- Issue #1686386: Tuple's tp_repr did not take into account the
4370 possibility of having a self-referential tuple, which is possible
4371 from C code. Nor did object's tp_str consider that a type's tp_str
4372 could do something that could lead to an inifinite recursion.
4373 Py_ReprEnter() and Py_EnterRecursiveCall(), respectively, fixed the
4374 issues.
Brett Cannon0b14f242007-09-30 19:45:10 +00004375
Georg Brandl3ee81df2008-05-17 18:14:43 +00004376- Issue #1164: It was possible to trigger deadlock when using the
4377 'print' statement to write to a file since the GIL was not released
4378 as needed. Now PyObject_Print() does the right thing along with
4379 various tp_print implementations of the built-in types and those in
4380 the collections module.
Brett Cannon01531592007-09-17 03:28:34 +00004381
Georg Brandl3ee81df2008-05-17 18:14:43 +00004382- Issue #1147: Exceptions were directly allowing string exceptions in

Brett Cannona0c05512007-09-10 21:38:27 +00004388
Brett Cannon1e534b52007-09-07 04:18:30 +00004389- Issue #1202533: Fix infinite recursion calls triggered by calls to
Georg Brandl3ee81df2008-05-17 18:14:43 +00004390 PyObject_Call() never calling back out to Python code to trigger
4391 recursion depth updates/checks. Required the creation of a static
4392 RuntimeError instance in case normalizing an exception put the
4393 recursion check value past its limit. Fixes crashers
4394 infinite_rec_(1|2|4|5).py.
Brett Cannon1e534b52007-09-07 04:18:30 +00004395

Neal Norwitz0ac60192007-05-27 04:08:54 +00004409- Add new attribute names for function objects. All the func_* become
Georg Brandl3ee81df2008-05-17 18:14:43 +00004410 __*__ attributes. (Some already existed, e.g., __doc__ and
4411 __name__.)
Neal Norwitz0ac60192007-05-27 04:08:54 +00004412
Neal Norwitz8b2bfbc2007-05-23 06:35:32 +00004413- Add -3 option to the interpreter to warn about features that are
4414 deprecated and will be changed/removed in Python 3.0.
4415
Georg Brandl2134e752007-05-21 20:34:16 +00004416- Patch #1686487: you can now pass any mapping after '**' in function
4417 calls.
4418
Collin Winter62903052007-05-18 23:11:24 +00004419- except clauses may now be spelled either "except E, target:" or
Georg Brandl3ee81df2008-05-17 18:14:43 +00004420 "except E as target:". This is to provide forwards compatibility
4421 with Python 3.0.

Vinay Sajip8549ce32007-05-06 17:53:37 +00004428- When __slots__ are set to a unicode string, make it work the same as
Neal Norwitzcbd9ee62007-04-14 05:25:50 +00004429 setting a plain string, ie don't expand to single letter identifiers.
4430
Raymond Hettinger13936692007-04-11 18:40:58 +00004431- Request #1191699: Slices can now be pickled.
4432
Raymond Hettinger4db5fe92007-04-12 04:10:00 +00004433- Request #1193128: str.translate() now allows a None argument for
4434 translations that only remove characters without re-mapping the
4435 remaining characters.
4436
Georg Brandl5cb76c12007-03-21 09:00:39 +00004437- Patch #1682205: a TypeError while unpacking an iterable is no longer
4438 masked by a generic one with the message "unpack non-sequence".
4439
Neal Norwitzaa754b72007-03-21 06:39:48 +00004440- Remove unused file Python/fmod.c.
4441
Guido van Rossum143b5642007-03-23 04:58:42 +00004442- Bug #1683368: The object.__init__() and object.__new__() methods are
4443 now stricter in rejecting excess arguments. The only time when
4444 either allows excess arguments is when it is not overridden and the
4445 other one is. For backwards compatibility, when both are
4446 overridden, it is a deprecation warning (for now; maybe a Py3k
Guido van Rossum234b1ff2007-03-23 19:39:01 +00004447 warning later). Also, type.__init__() insists on the same signature
4448 as supported by type.__new__().
Guido van Rossum143b5642007-03-23 04:58:42 +00004449
Georg Brandl3ee81df2008-05-17 18:14:43 +00004450- Patch #1675423: PyComplex_AsCComplex() now tries to convert an
4451 object to complex using its __complex__() method before falling back
4452 to the __float__() method. Therefore, the functions in the cmath
4453 module now can operate on objects that define a __complex__()
4454 method.
Georg Brandl2b869942007-03-17 16:08:45 +00004455
Georg Brandl3ee81df2008-05-17 18:14:43 +00004456- Patch #1623563: allow __class__ assignment for classes with
4457 __slots__. The old and the new class are still required to have the
4458 same slot names.
Žiga Seilnacht6f2d09c2007-03-16 11:59:38 +00004459

4464 ``object.__reduce_ex__()`` is called with an object that is faking
4465 its type.

4471
Georg Brandl7b9c5552007-03-12 14:30:05 +00004472- Bug #1678647: write a newline after printing an exception in any
4473 case, even when converting the value to a string failed.
4474
Georg Brandl871f1bc2007-03-12 13:17:36 +00004475- The dir() function has been extended to call the __dir__() method on
Georg Brandl3ee81df2008-05-17 18:14:43 +00004476 its argument, if it exists. If not, it will work like before. This
4477 allows customizing the output of dir() in the presence of a
4478 __getattr__().

Collin Winter276887b2007-03-12 16:11:39 +00004480- Patch #922167: Python no longer segfaults when faced with infinitely
4481 self-recursive reload() calls (as reported by bug #742342).
4482
Georg Brandl3ee81df2008-05-17 18:14:43 +00004483- Patch #1675981: remove unreachable code from ``type.__new__()``

Georg Brandl3ee81df2008-05-17 18:14:43 +00004486- Patch #1491866: change the complex() constructor to allow
4487 parthensized forms. This means complex(repr(x)) now works instead of
4488 raising a ValueError.
Collin Wintere38051d2007-03-09 20:33:07 +00004489
Georg Brandlaa2321b2007-03-07 00:40:28 +00004490- Patch #703779: unset __file__ in __main__ after running a file. This
Georg Brandl3ee81df2008-05-17 18:14:43 +00004491 makes the filenames the warning module prints much more sensible
4492 when a PYTHONSTARTUP file is used.
Georg Brandlaa2321b2007-03-07 00:40:28 +00004493

Georg Brandl0fca97a2007-03-05 22:28:08 +00004505- Patch #1674228: when assigning a slice (old-style), check for the
4506 sq_ass_slice instead of the sq_slice slot.
4507
Georg Brandl3ee81df2008-05-17 18:14:43 +00004508- When printing an unraisable error, don't print exceptions. before
4509 the name. This duplicates the behavior whening normally printing
4510 exceptions.

Georg Brandl3ee81df2008-05-17 18:14:43 +00005043 AttributeError instead of an IOError when the server's response
5044 didn't contain a valid HTTP status line.
Georg Brandlf66b6032007-03-14 08:27:52 +00005045

5060
Georg Brandl3ee81df2008-05-17 18:14:43 +00005061- Patch #1530482: add pydoc.render_doc() which returns the

5076
Georg Brandl92a6bae2007-03-13 17:43:32 +00005077- Patch #1603688: ConfigParser.SafeConfigParser now checks values that
Georg Brandl3ee81df2008-05-17 18:14:43 +00005078 are set for invalid interpolation sequences that would lead to
5079 errors on reading back those values.

5120

5122 returned string up to the first NUL character.

5133
Georg Brandl3ee81df2008-05-17 18:14:43 +00005134- unittest now verifies more of its assumptions. In particular,
5135 TestCase and TestSuite subclasses (not instances) are no longer
5136 accepted in TestSuite.addTest(). This should cause no
5137 incompatibility since it never made sense with ordinary subclasses
5138 -- the failure just occurred later, with a more cumbersome
5139 exception.

5510 complex, tuple, list, dict, set, and frozenset. Formerly, it would

Georg Brandl3ee81df2008-05-17 18:14:43 +00005528 time so that opening a database previously created with the DB_DUP
5529 or DB_DUPSORT flag set will keep the proper behavior on subsequent
5530 opens. Specifically: dictionary assignment to a DB object will
5531 replace all values for a given key when the database allows
5532 duplicate values. DB users should use DB.put(k, v) when they want
5533 to store duplicates; not DB[k] = v.

5540 characters with ASCII value less than 32. Also, it correctly quotes
5541 dots only if they occur on a single line, as opposed to the previous
5542 behavior of quoting dots if they are the second character of any
5543 line.
