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.
45
Benjamin Peterson821a8ea2010-04-16 22:35:38 +000046- Issue #8417: Raise an OverflowError when an integer larger than sys.maxsize is

68- Issue #8483: asyncore.dispatcher's __getattr__ method produced confusing
69 error messages when accessing undefined class attributes because of the cheap
70 inheritance with the underlying socket object.
71 The cheap inheritance has been deprecated.
72
Tarek Ziadé38f81222010-05-05 22:15:31 +000073- Issue #4265: shutil.copyfile() was leaking file descriptors when disk fills.

82 ASCII with backslashreplace error handler if str(value) failed
83
Mark Dickinson4f96f5f2010-05-04 14:25:50 +000084- Issue #8567: Fix precedence of signals in Decimal module: when a
85 Decimal operation raises multiple signals and more than one of those
86 signals is trapped, the specification determines the order in which
87 the signals should be handled. In many cases this order wasn't
88 being followed, leading to the wrong Python exception being raised.
89
Antoine Pitrouf7fd8e42010-05-03 16:25:33 +000090- Issue #7865: The close() method of :mod:`io` objects should not swallow

119 suites, the IGNORE_EXCEPTION_DETAIL directive now also ignores the module
Nick Coghlan54677da2010-04-28 14:34:30 +0000120 location of the raised exception. Based on initial patch by Lennart
121 Regebro.
Nick Coghlandfb45df2010-04-28 14:29:06 +0000122
Antoine Pitrou4c7bcf12010-04-27 22:03:37 +0000123- Issue #8086: In :func:`ssl.DER_cert_to_PEM_cert()`, fix missing newline

Antoine Pitroua6240402010-04-25 21:40:32 +0000134- Issue #2302: Fix a race condition in SocketServer.BaseServer.shutdown,
135 where the method could block indefinitely if called just before the
136 event loop started running. This also fixes the occasional freezes
137 witnessed in test_httpservers.
138
Antoine Pitroufc69af12010-04-24 20:04:58 +0000139- Issue #5103: SSL handshake would ignore the socket timeout and block
140 indefinitely if the other end didn't respond.
141
Antoine Pitrou4d3e3722010-04-24 19:57:01 +0000142- The do_handshake() method of SSL objects now adjusts the blocking mode of

152
Sean Reifscheiderf6ce3cb2010-04-23 08:31:55 +0000153- Issue #8451: Syslog module now uses basename(sys.argv[0]) instead of
154 the string "python" as the *ident*. openlog() arguments are all optional
155 and keywords.
156
Antoine Pitroua5c4b552010-04-22 23:33:02 +0000157- Issue #8108: Fix the unwrap() method of SSL objects when the socket has
158 a non-infinite timeout. Also make that method friendlier with applications
159 wanting to continue using the socket in clear-text mode, by disabling
160 OpenSSL's internal readahead. Thanks to Darryl Miles for guidance.
161
Antoine Pitrouc715a9e2010-04-21 19:28:03 +0000162- Issue #8484: Load all ciphers and digest algorithms when initializing
163 the _ssl extension, such that verification of some SSL certificates

188 filename and date, conforming to the 'standards' they were originally
189 designed to follow. This improves compatibility with patch tools.
190
R. David Murray27ef9372010-04-12 14:26:06 +0000191- Issue #7472: Fixed typo in email.encoders module; messages using ISO-2022
192 character sets will now consistently use a Content-Transfer-Encoding of
193 7bit rather than sometimes being marked as 8bit.

229 (Optimization was unintentionally turned on in gcc --with-pydebug builds in
230 2.7 beta1 as a result of the issue #1628484 fix, combined with autoconf's
231 strange choice of default CFLAGS produced by AC_PROG_CC for gcc.)

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

Georg Brandl4fabac52010-04-14 08:53:38 +0000317 to simplify the specification of rich comparisons.
Raymond Hettingera551f312010-04-04 18:34:45 +0000318
Raymond Hettingerbb006cf2010-04-04 21:45:01 +0000319- The functools module also adds cmp_to_key() as a tool to transition
Raymond Hettingera551f312010-04-04 18:34:45 +0000320 old-style comparison functions to new-style key-functions.

Mark Dickinson7c63eee2010-04-02 22:27:36 +0000322- Issue #8294: The Fraction constructor now accepts Decimal and float
323 instances directly.
324
Mark Dickinsone096e822010-04-02 10:17:07 +0000325- Issue #7279: Comparisons involving a Decimal signaling NaN now
326 signal InvalidOperation instead of returning False. (Comparisons
Mark Dickinsonf3eeca12010-04-02 10:35:12 +0000327 involving a quiet NaN are unchanged.) Also, Decimal quiet NaNs
328 are now hashable; Decimal signaling NaNs remain unhashable.

Mark Dickinson99d80962010-04-02 08:53:22 +0000330- Issue #2531: Comparison operations between floats and Decimal
331 instances now return a result based on the numeric values of the
332 operands; previously they returned an arbitrary result based on
333 the relative ordering of id(float) and id(Decimal).
334
Barry Warsawf7f2d6f2010-03-31 21:07:16 +0000335- Issue #8233: When run as a script, py_compile.py optionally takes a single
336 argument `-` which tells it to read files to compile from stdin. Each line
337 is read on demand and the named file is compiled immediately. (Original
338 patch by Piotr Ożarowski).

Mark Dickinson9588d992010-03-27 11:14:37 +0000348- Comparisons using one of <, <=, >, >= between a complex instance and
349 a Fractions instance now raise TypeError instead of returning
350 True/False. This makes Fraction <=> complex comparisons consistent with
351 int <=> complex, float <=> complex, and complex <=> complex comparisons.

Mark Dickinson4846a8e2010-04-03 14:05:10 +0000450- Issue #8300: When passing a non-integer argument to struct.pack with any
451 integer format code, struct.pack first attempts to convert the non-integer
452 using its __index__ method. If that method is non-existent or raises
453 TypeError it goes on to try the __int__ method, as described below.
454
Georg Brandlba83f822010-03-14 09:50:54 +0000455- Issue #1530559: When passing a non-integer argument to struct.pack with *any*
456 integer format code (one of 'bBhHiIlLqQ'), struct.pack attempts to use the
457 argument's __int__ method to convert to an integer before packing. It also
458 produces a DeprecationWarning in this case. (In Python 2.6, the behaviour
459 was inconsistent: __int__ was used for some integer codes but not for others,
460 and the set of integer codes for which it was used differed between native
461 packing and standard packing.)

Georg Brandlba83f822010-03-14 09:50:54 +0000759 file position when calling `truncate()`. It would previously change the file
760 position to the given argument, which goes against the tradition of

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

857Core and Builtins
858-----------------
859
Georg Brandlba83f822010-03-14 09:50:54 +0000860- The ``__complex__()`` method is now looked up on the class of instances to
861 make it consistent with other special methods.
Benjamin Petersonecdae192010-01-04 00:43:01 +0000862
Antoine Pitrou5b7139a2010-01-02 21:12:58 +0000863- Issue #7462: Implement the stringlib fast search algorithm for the `rfind`,
864 `rindex`, `rsplit` and `rpartition` methods. Patch by Florent Xicluna.
865
Mark Dickinson1b34d252010-01-01 17:27:30 +0000866- Issue #5080: A number of functions and methods previously produced a
Georg Brandlba83f822010-03-14 09:50:54 +0000867 DeprecationWarning when passed a float argument where an integer was expected.
868 These functions and methods now raise TypeError instead. The majority of the
869 effects of this change are in the extension modules, but some core functions
870 and methods are affected: notably the 'chr', 'range' and 'xrange' builtins,
871 and many unicode/str methods.
Mark Dickinson1b34d252010-01-01 17:27:30 +0000872

Amaury Forgeot d'Arc8645a5c2009-12-29 22:03:38 +0000881- Issue #7413: Passing '\0' as the separator to datetime.datetime.isoformat()
882 used to drop the time part of the result.
883
Georg Brandlba83f822010-03-14 09:50:54 +0000884- Issue #1811: Improve accuracy and cross-platform consistency for true division
885 of integers: the result of a/b is now correctly rounded for ints a and b (at
886 least on IEEE 754 platforms), and in particular does not depend on the
887 internal representation of a long.
Mark Dickinson46572832009-12-27 14:55:57 +0000888
Georg Brandlba83f822010-03-14 09:50:54 +0000889- Issue #6108: ``unicode(exception)`` and ``str(exception)`` should return the
890 same message when only ``__str__()`` (and not ``__unicode__()``) is overridden
891 in the subclass.

Ronald Oussoren92919a62009-12-24 13:30:58 +0000894 executables on OSX.
895
Georg Brandlba83f822010-03-14 09:50:54 +0000896 These executables now work properly with the arch(1) command: ``arch -ppc
897 python`` will start a universal binary version of python in PPC mode (unlike
898 previous releases).
Ronald Oussoren92919a62009-12-24 13:30:58 +0000899
Georg Brandlba83f822010-03-14 09:50:54 +0000900- Issue #1680159: Unicode coercion during an 'in' operation no longer masks the

Georg Brandlba83f822010-03-14 09:50:54 +0000921 renaming of `cPickle` to `pickle`. The warning was annoying since there's no
922 alternative to cPickle if you care about performance. Patch by Florent

1064 constructors; old-style and new-style numeric formatting; serialization and
1065 deserialization of floats and complex numbers using marshal, pickle and json;
1066 parsing of float and imaginary literals in Python code; Decimal-to-float
1067 conversion.

Georg Brandlba83f822010-03-14 09:50:54 +00001069 The conversions use a Python-adapted version of David Gay's well-known dtoa.c,
1070 providing correctly-rounded strtod and dtoa C functions. This code is
1071 supported on Windows, and on Unix-like platforms using gcc, icc or suncc as
1072 the C compiler. There may be a small number of platforms on which correct
1073 operation of this code cannot be guaranteed, so the code is not used: notably,
1074 this applies to platforms where the C double format is not IEEE 754 binary64,
1075 and to platforms on x86 hardware where the x87 FPU is set to 64-bit precision
1076 and Python's configure script is unable to determine how to change the FPU
1077 precision. On these platforms conversions use the platform strtod and dtoa,
1078 as before.

Georg Brandlba83f822010-03-14 09:50:54 +00001080- Issue #7117: Backport round implementation from Python 3.x. ``round()`` now
1081 uses the correctly-rounded string <-> float conversions described above (when
1082 available), and so produces correctly rounded results that will display nicely
1083 under the float repr. There are two related small changes: (1) round now
1084 accepts any class with an ``__index__()`` method for its second argument (but
1085 no longer accepts floats for the second argument), and (2) an excessively
1086 large second integer argument (e.g., ``round(1.234, 10**100)``) no longer
1087 raises an exception.

1466 this code path is really executed because I cannot move to such directory on

1493 PyUnicode_DecodeUTF8() once, remember the result and output it in a second

Georg Brandlba83f822010-03-14 09:50:54 +00002664 - Packing a float now always gives a Deprecation Warning. Previously it

Georg Brandlba83f822010-03-14 09:50:54 +00002667 - If x is not an int, long or float, then packing x will always result in
2668 struct.error. Previously an x with an __int__ method could be packed by
2669 'b', 'B', 'h', 'H', 'i', 'l', '*b', '*h' ,'*i', '*l', and an x with a
2670 __long__ method could be packed by 'q', 'Q', '*q', '*Q'; for x with
2671 neither __int__ nor __long__, TypeError used to be raised (with a
2672 confusing error message) for 'I', 'L', '*B', '*H', '*I', '*L', and
2673 struct.error in other cases.

2676 argument with an __int__ method can be packed, but use of this feature

Amaury Forgeot d'Arc05e34492008-09-10 22:04:45 +00002870- Issue #3743: In a few places, PY_FORMAT_SIZE_T was incorrectly used with

2872 PY_FORMAT_SIZE_T is designed to select the correct format for the OS
2873 ``printf`` function, whereas PyString_FromFormat has an independent

2971 warnings.catch_warnings() along with some API cleanup. Expanding the tests
2972 for catch_warnings() also led to an improvement in the raising of a
2973 DeprecationWarning related to warnings.warn_explicit().

Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00003039What's New in Python 2.6 beta 3?
3040================================
3041
Barry Warsaw07a4a382008-08-21 01:15:08 +00003042*Release date: 20-Aug-2008*
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00003043
3044Core and Builtins
3045-----------------
3046
Guido van Rossumf8402962008-08-20 15:01:50 +00003047- Issue #1878: Remove Py_TPFLAGS_HAVE_VERSION_TAG from
3048 Py_TPFLAGS_DEFAULT when not building the core. This means 3rd party
3049 extensions do not automatically benefit from the class attribute
3050 cache; they will have to explicitly add Py_TPFLAGS_HAVE_VERSION_TAG
3051 to their tp_flags field if they care. This is a backwards
3052 compatibility feature; in 3.0, all types will use the cache by
3053 default.
3054
Benjamin Petersonf647dc12008-08-20 01:27:30 +00003055- Keyword arguments can now follow starred arguments. (``f(a, *args,
3056 keyword=23)`` is now valid syntax.)
3057
Thomas Heller0ad5ae02008-08-19 19:25:04 +00003058- ctypes function pointers that are COM methods have a boolean True
3059 value again.
3060
Martin v. Löwisf91d46a2008-08-12 14:49:50 +00003061- Issue #3139: Make buffer-interface thread-safe wrt. PyArg_ParseTuple,
3062 by denying s# to parse objects that have a releasebuffer procedure,
3063 and introducing s*.
3064
Georg Brandl1e13ea92008-08-11 09:07:59 +00003065- Issue #3537: Fix an assertion failure when an empty but presized dict
3066 object was stored in the freelist.
3067
Mark Dickinsonb6467572008-08-04 21:30:09 +00003068- Issue #1481296: Make long(float('nan')) and int(float('nan')) raise
3069 ValueError consistently across platforms.
3070
Amaury Forgeot d'Arc39fd6722008-07-31 21:28:03 +00003071- Issue #3479: On platforms where sizeof(int) is smaller than sizeof(long)
3072 (64bit Unix, for example), unichr() would truncate its argument and return
3073 u'\x00' for unichr(2**32). Now it properly raises an OverflowError.
3074
Neal Norwitze7d8be82008-07-31 17:17:14 +00003075- Apply security patches from Apple.
3076
Amaury Forgeot d'Arc246daed2008-07-31 00:42:16 +00003077- Issue #2542: Now that issubclass() may call arbitrary code, ensure that
3078 PyErr_ExceptionMatches returns 0 when an exception occurs there.
3079
Antoine Pitrou92f82162008-07-25 22:22:08 +00003080- Issue #1819: function calls with several named parameters are now on
3081 average 35% faster (as measured by pybench).
3082
Amaury Forgeot d'Arce4921fe2008-07-21 22:00:38 +00003083- Issue #2378: An unexpected UnboundLocalError or NameError could appear when
3084 the python debugger steps into a class statement: the free variables (local
3085 variables defined in an outer scope) would be deleted from the outer scope.
3086
Gregory P. Smith0470bab2008-07-22 04:46:32 +00003087- Issue #2620: Overflow checking when allocating or reallocating memory
3088 was not always being done properly in some python types and extension
3089 modules. PyMem_MALLOC, PyMem_REALLOC, PyMem_NEW and PyMem_RESIZE have
3090 all been updated to perform better checks and places in the code that
3091 would previously leak memory on the error path when such an allocation
3092 failed have been fixed.
3093

3095-------
3096
Hirokazu Yamamoto838c79f2008-08-20 13:14:07 +00003097- Issue #3612: Added some missing basic types in ctypes.wintypes.
3098
Benjamin Petersone977ad42008-08-20 01:42:01 +00003099- The methods ``is_in_tuple()``, ``is_vararg()``, and ``is_keywordarg()`` of
3100 symtable.Symbol have been deprecated for removal in 3.0 and the next release.
3101
Amaury Forgeot d'Arc351ffb82008-08-18 19:23:47 +00003102- Issue #2234: distutils failed for some versions of the cygwin compiler. The
3103 version reported by these tools does not necessarily follow the python
3104 version numbering scheme, so the module is less strict when parsing it.
3105
Nick Coghlanf70385a2008-08-18 12:42:46 +00003106- Issue #2235: Added Py3k warnings for types which will become unhashable
3107 under the stricter __hash__ inheritance rules in 3.0. Several types
3108 which did not meet the rules for hash invariants and were already
3109 unhashable in 3.0 have now been explicitly flagged as unhashable in
3110 2.6 as well (collections.Mapping, collections.Set, unittest.TestSuite,
3111 xml.dom.minidom.NamedNodeMap, numbers.Number, UserList.UserList)
3112
Brett Cannon88f801d2008-08-18 00:46:22 +00003113- Update __all__ for cookielib, csv, os, urllib2, and weakref to include things

3115
Brett Cannon7b96f072008-08-18 00:41:11 +00003116- Remove an unneeded import of abc.ABCMeta from 'inspect'.
3117
Brett Cannon46225e72008-08-18 00:36:52 +00003118- Remove unneeded imports of 'sys' and 'warnings' from 'io'.

Brett Cannon25c9d6a2008-08-17 22:10:11 +00003120- Remove unneeded imports of 'warnings' from shelve, filecmp, and dummy_thread.
3121
Hirokazu Yamamoto41a81eb2008-08-17 13:10:46 +00003122- Issue #3575: Incremental decoder's decode function now takes bytearray
3123 by using 's*' instead of 't#'.
3124
Mark Dickinson3e4caeb2009-02-21 20:27:01 +00003125- Issue #2222: Fixed reference leak when occurred os.rename()
Hirokazu Yamamoto7f30a682008-08-17 09:46:56 +00003126 fails unicode conversion on 2nd parameter. (windows only)
3127
Facundo Batista94f243a2008-08-17 03:38:39 +00003128- Issue 2464. urllib2 now supports a malformation in the URL received
3129 in a redirect.
3130
Brett Cannonabe423e2008-08-16 21:47:07 +00003131- Silence the DeprecationWarning raised when importing mimetools in
Brett Cannon721b1452008-08-16 22:00:27 +00003132 BaseHTTPServer, cgi (and rfc822), httplib.
Brett Cannonabe423e2008-08-16 21:47:07 +00003133
Facundo Batistaeb90b782008-08-16 14:44:07 +00003134- Issue #2776: fixed small issue when handling an URL with double slash
3135 after a 302 response in the case of not going through a proxy.
3136
Antoine Pitroub90a8be2008-08-15 21:03:21 +00003137- Issue #2676: in the email package, content-type parsing was hanging on
3138 pathological input because of quadratic or exponential behaviour of a
3139 regular expression.
3140
Antoine Pitrou11ec65d2008-08-14 21:04:30 +00003141- Issue #3476: binary buffered reading through the new "io" library is now
3142 thread-safe.
3143
Brett Cannonbf3157b2008-08-14 05:00:03 +00003144- Silence the DeprecationWarning of rfc822 when it is imported by mimetools
3145 since mimetools itself is deprecated. Because modules are cached, all
3146 subsequent imports of rfc822 will not raise a visible DeprecationWarning.
3147
Antoine Pitrou9fcd4b32008-08-11 17:21:36 +00003148- Issue #3134: shutil referenced undefined WindowsError symbol.
3149
Robert Schuppenies14646332008-08-10 11:01:53 +00003150- Issue #1342811: Fix leak in Tkinter.Menu.delete. Commands associated to
3151 menu entries were not deleted.
3152
Brett Cannon83e81842008-08-09 23:30:55 +00003153- Copied the implementation of reduce() to _functools.reduce() to have a
3154 version that did not raise a DeprecationWarning under -3.
3155
Antoine Pitrou76b8bee2008-08-09 17:27:23 +00003156- Issue #3205: When iterating over a BZ2File fails allocating memory, raise
3157 a MemoryError rather than silently stop the iteration.
3158
Guido van Rossum59ce9012008-08-09 14:55:34 +00003159- Issue #3487: sre "bytecode" validator. Passing invalid "re-bytecode"
3160 to _sre.compile() will now be rejected. This should not affect anybody
3161 since the re.compile() function never generates invalid re-bytecode.
3162
Skip Montanaroa032bf42008-08-08 22:52:51 +00003163- Issue #3436: Make csv.DictReader's fieldnames attribute a property so that
3164 upon first access it can be automatically initialized from the csv file if
3165 it wasn't initialized during instantiation.
3166
Brett Cannon3aa2a492008-08-06 22:28:09 +00003167- Issue #2338: Create imp.reload() to help with transitioning to Python 3.0 as
3168 the reload() built-in has been removed.
3169
Brett Cannon7e30b672008-08-04 21:52:25 +00003170- Changed code in the following modules/packages to remove warnings raised
Brett Cannonc1b76e42008-08-09 23:06:16 +00003171 while running under the ``-3`` flag: aifc, asynchat, asyncore, bdb, bsddb,

Antoine Pitroude781a42008-08-09 12:43:23 +00003182 asking for a specific length. This problem only affected files opened
3183 using the new "io" module, not the built-in open() function.
Benjamin Peterson01a24322008-07-28 23:35:27 +00003184

Antoine Pitrou5fdfa3e2008-07-25 19:42:26 +00003208- Issue #3394: zipfile.writestr sets external attributes when passed a
3209 file name rather than a ZipInfo instance, so files are extracted with
3210 mode 0600 rather than 000 under Unix.
3211
Gregory P. Smitha36f8fe2008-08-04 00:13:29 +00003212- Issue #1857: subprocess.Popen.poll gained an additional _deadstate keyword
3213 argument in python 2.5, this broke code that subclassed Popen to include its

3225 interaction with the tp_hash slot (added in 2.6b2) are now documented
3226
Nick Coghlan2a0c2b12008-08-04 12:47:17 +00003227- Issue #643841: The language reference now provides more detailed
3228 coverage of the lookup process for special methods. The disclaimers
3229 regarding lack of coverage of new-style classes have also been
3230 removed, since the coverage is now fairly reasonable.

Raymond Hettingere3ae6552008-06-20 04:18:15 +00003233What's New in Python 2.6 beta 2?
3234================================
3235
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00003236*Release date: 17-Jul-2008*
3237
Raymond Hettingere3ae6552008-06-20 04:18:15 +00003238Core and Builtins
3239-----------------
3240
Georg Brandl3e483f62008-07-16 22:57:41 +00003241- Issue #3156: Fix inconsistent behavior of the bytearray type: all
3242 its methods now allow for items objects that can be converted to
3243 an integer using operator.index().
3244
Mark Dickinson64b7e502008-07-16 09:40:03 +00003245- Issue #3360: Fix incorrect parsing of '020000000000.0', which
3246 produced a ValueError instead of giving the correct float.
3247
Eric Smitha5fa5a22008-07-16 00:11:49 +00003248- Issue #3083: Add alternate (#) formatting for bin, oct, hex output
3249 for str.format(). This adds the prefix 0b, 0o, or 0x, respectively.
3250
Mark Dickinson7103aa42008-07-15 19:08:33 +00003251- Issue #3008: the float type has a new instance method 'float.hex'
3252 and a new class method 'float.fromhex' to convert floating-point
3253 numbers to and from hexadecimal strings, respectively.
3254
Nick Coghlan6d6bd442008-07-15 15:40:22 +00003255- Issue #2235: __hash__ is once again inherited by default. To allow
3256 collections.Hashable to remain meaningful in the presence of the
3257 default hash implementation (object.__hash__), it is now possible
3258 to explicit block inheritance of hash by setting __hash__=None at
3259 the Python level, or tp_hash=PyObject_HashNotImplemented at the C
3260 level.
3261
Nick Coghlanb028f502008-07-13 14:52:36 +00003262- Issue #3221: Issue a RuntimeWarning instead of raising SystemError if
3263 the parent module cannot be found while performing an absolute import.
3264 This means that an incorrectly defined __package__ attribute will
3265 now only prevent relative imports in that module rather than causing
3266 all imports from that module to fail.
3267
Nick Coghlan14ff9942008-07-08 14:21:42 +00003268- Issue #2517: Allow unicode messages in Exceptions again by correctly
3269 bypassing the instance dictionary when looking up __unicode__ on
3270 new-style classes.
3271
Amaury Forgeot d'Arcbdd941f2008-07-01 20:38:04 +00003272- Issue #3242: Fix a crash inside the print statement, if sys.stdout is
3273 set to a custom object whose write() method happens to install
3274 another file in sys.stdout.
3275
Amaury Forgeot d'Arc1f40c8a2008-06-30 22:42:40 +00003276- Issue #3088: Corrected a race condition in classes derived from
3277 threading.local: the first member set by a thread could be saved in
3278 another thread's dictionary.
3279
Mark Dickinson1ec2fcd2008-06-20 14:53:43 +00003280- Issue #3004: Minor change to slice.indices(): the start and stop
3281 arguments are now treated identically, making the behaviour easier
3282 to describe and understand. For example, slice(None, -10,
3283 1).indices(9) now returns (0, 0, 1) instead of (0, -1, 1), and
3284 slice(None, 10, -1).indices(10) returns (9, 9, -1) instead of (9,
3285 10, -1).
3286
Georg Brandl278fc502008-07-19 12:46:12 +00003287- Issue #3219: Calling a function with repeated keyword arguments,
3288 f(a=2, a=23), would not cause a syntax error. This was a regression
3289 from 2.4 caused by the switch to the new compiler.
Benjamin Peterson175e4d92008-07-01 19:34:52 +00003290
Georg Brandl278fc502008-07-19 12:46:12 +00003291- Issue #2862: Make int and float freelist management consistent with
3292 other freelists. Changes their CompactFreeList apis into
3293 ClearFreeList apis and calls them via gc.collect().

Thomas Heller57adf222008-08-14 19:10:48 +00003298- Issue #3554: ctypes.string_at and ctypes.wstring_at did call Python
3299 api functions without holding the GIL, which could lead to a fatal
3300 error when they failed.
3301
Martin v. Löwisaabf4042008-08-02 07:20:25 +00003302- Issue #799428: Fix Tkinter.Misc._nametowidget to unwrap Tcl command objects.

3311 ForkingPickler.register() to resolve conflict with ctypes.
3312
Vinay Sajip51e65192008-07-18 09:01:10 +00003313- Issue #3090: Fixed ARCHFLAGS parsing on OS/X
Jesse Noller13e9d582008-07-16 14:32:36 +00003314
Thomas Heller880f5292008-07-15 19:39:38 +00003315- Issue #3313: Fixed a crash when a failed dlopen() call does not set
3316 a valid dlerror() message.
3317
Thomas Heller2bad6572008-07-15 17:19:50 +00003318- Issue #3258: Fixed a crash when a ctypes POINTER type to an
3319 incomplete structure was created.

3324
Andrew M. Kuchlingcc3f2b12008-07-10 14:43:31 +00003325- Issue #3301: Bisect module behaved badly when lo was negative.
Raymond Hettinger3cd1e422008-07-10 14:03:19 +00003326
Amaury Forgeot d'Arc0f7cddc2008-07-06 21:34:39 +00003327- Issue #839496: SimpleHTTPServer used to open text files in text mode. This is
3328 both unnecessary (HTTP allows text content to be sent in several forms) and
Andrew M. Kuchlingcc3f2b12008-07-10 14:43:31 +00003329 wrong because the actual transmitted size could differ from the
Amaury Forgeot d'Arc0f7cddc2008-07-06 21:34:39 +00003330 content-length. The problem had been corrected in the 2.4 branch, but never
3331 merged into trunk.
3332
Georg Brandle78fbcc2008-07-05 10:13:36 +00003333- Issue #2663: add filtering capability to shutil.copytree().

Andrew M. Kuchlingcc3f2b12008-07-10 14:43:31 +00003344 when completed.
Facundo Batista66c52772008-07-02 16:52:55 +00003345
Nick Coghlanc060b0e2008-07-02 13:09:19 +00003346- Issue #3190: Pydoc now hides the automatic module attribute __package__ (the
3347 handling is now the same as that of other special attributes like __name__).
3348
Brett Cannon8bb8fa52008-07-02 01:57:08 +00003349- Issue #2885 (partial): The urllib.urlopen() function has been deprecated for
3350 removal in Python 3.0 in favor of urllib2.urlopen().

3802 original Python code has been kept as backup). This will allow for
3803 using the 'warning's machinery in such places as the parser where
3804 use of pure Python code is not possible. Both the ``showarning()``
3805 and ``formatwarning()`` gain an optional 'line' argument which is
3806 not called by default for backwards-compatibility reasons. Setting
3807 ``warnings.showwarning()`` to an implementation that lacks support
3808 for the ``line`` argument will raise a DeprecationWarning.

Georg Brandl3ee81df2008-05-17 18:14:43 +00003871- Issue #2550: The approach used by client/server code for obtaining
3872 ports to listen on in network-oriented tests has been refined in an
3873 effort to facilitate running multiple instances of the entire
3874 regression test suite in parallel without issue.
3875 test_support.bind_port() has been fixed such that it will always
3876 return a unique port -- which wasn't always the case with the
3877 previous implementation, especially if socket options had been set
3878 that affected address reuse (i.e. SO_REUSEADDR, SO_REUSEPORT). The
3879 new implementation of bind_port() will actually raise an exception
3880 if it is passed an AF_INET/SOCK_STREAM socket with either the
3881 SO_REUSEADDR or SO_REUSEPORT socket option set. Furthermore, if
3882 available, bind_port() will set the SO_EXCLUSIVEADDRUSE option on
3883 the socket it's been passed. This currently only applies to
3884 Windows. This option prevents any other sockets from binding to the
3885 host/port we've bound to, thus removing the possibility of the
3886 'non-deterministic' behaviour, as Microsoft puts it, that occurs
3887 when a second SOCK_STREAM socket binds and accepts to a host/port
3888 that's already been bound by another socket. The optional preferred
3889 port parameter to bind_port() has been removed. Under no
3890 circumstances should tests be hard coding ports!
3891
3892 test_support.find_unused_port() has also been introduced, which will
3893 pass a temporary socket object to bind_port() in order to obtain an
3894 unused port. The temporary socket object is then closed and
3895 deleted, and the port is returned. This method should only be used
3896 for obtaining an unused port in order to pass to an external program
3897 (i.e. the -accept [port] argument to openssl's s_server mode) or as
3898 a parameter to a server-oriented class that doesn't give you direct
3899 access to the underlying socket used.
3900
3901 Finally, test_support.HOST has been introduced, which should be used
3902 for the host argument of any relevant socket calls (i.e. bind and
3903 connect).
Trent Nelsone41b0062008-04-08 23:47:30 +00003904
3905 The following tests were updated to following the new conventions:
Georg Brandl3ee81df2008-05-17 18:14:43 +00003906 test_socket, test_smtplib, test_asyncore, test_ssl, test_httplib,
Trent Nelsone41b0062008-04-08 23:47:30 +00003907 test_poplib, test_ftplib, test_telnetlib, test_socketserver,
3908 test_asynchat and test_socket_ssl.
3909
Georg Brandl3ee81df2008-05-17 18:14:43 +00003910 It is now possible for multiple instances of the regression test
3911 suite to run in parallel without issue.

4178-----------------
4179
Fred Drakea8ee94b2008-03-01 02:45:07 +00004180- Issue #2051: pyc and pyo files are no longer created with permission
Barry Warsaw52973612008-03-01 02:23:38 +00004181 644. The mode is now inherited from the py file.

Georg Brandlad61bc82008-02-23 15:11:18 +00004183- Issue #2067: file.__exit__() now calls subclasses' close() method.
4184
4185- Patch #1759: Backport of PEP 3129 class decorators.
Christian Heimes5224d282008-02-23 15:01:05 +00004186
Vinay Sajipb7edfc42008-04-02 21:10:23 +00004187- Issue #1881: An internal parser limit has been increased. Also see
Facundo Batistafc2d0102008-02-23 12:01:13 +00004188 issue 215555 for a discussion.
4189
Eric Smitha73fbe72008-02-23 03:09:44 +00004190- Added the future_builtins module, which contains hex() and oct().
4191 These are the PEP 3127 version of these functions, designed to be
4192 compatible with the hex() and oct() builtins from Python 3.0. They
4193 differ slightly in their output formats from the existing, unchanged
4194 Python 2.6 builtins. The expected usage of the future_builtins
4195 module is:
4196 from future_builtins import hex, oct
4197
Eric Smith7ef40bf2008-02-20 23:34:22 +00004198- Issue #1600: Modifed PyOS_ascii_formatd to use at most 2 digit
4199 exponents for exponents with absolute value < 100. Follows C99
4200 standard. This is a change on Windows, which would use 3 digits.
4201 Also, added 'n' to the formats that PyOS_ascii_formatd understands,
4202 so that any alterations it does to the resulting string will be
4203 available in stringlib/formatter.h (for float.__format__).
4204
Eric Smith5a3c1352008-02-19 13:21:56 +00004205- Implemented PEP 3101, Advanced String Formatting. This adds a new
4206 builtin format(); a format() method for str and unicode; a
4207 __format__() method to object, str, unicode, int, long, float, and
4208 datetime; the class string.Formatter; and the C API
4209 PyObject_Format().
4210
Georg Brandl3ee81df2008-05-17 18:14:43 +00004211- Fixed several potential crashes, all caused by specially crafted
4212 __del__ methods exploiting objects in temporarily inconsistent
4213 state.
Amaury Forgeot d'Arc632fad32008-02-16 20:55:24 +00004214
Vinay Sajipb7edfc42008-04-02 21:10:23 +00004215- Issue #2115: Important speedup in setting __slot__ attributes. Also
Georg Brandl3ee81df2008-05-17 18:14:43 +00004216 prevent a possible crash: an Abstract Base Class would try to access
4217 a slot on a registered virtual subclass.
Amaury Forgeot d'Arc60d6c7f2008-02-15 21:22:45 +00004218

Georg Brandl3ee81df2008-05-17 18:14:43 +00004222- Clear all free lists during a gc.collect() of the highest generation
4223 in order to allow pymalloc to free more arenas. Python may give back
4224 memory to the OS earlier.
Christian Heimes3b718a72008-02-14 12:47:33 +00004225
Georg Brandl3ee81df2008-05-17 18:14:43 +00004226- Issue #2045: Fix an infinite recursion triggered when printing a
4227 subclass of collections.defaultdict, if its default_factory is set
4228 to a bound method.
Amaury Forgeot d'Arcb01aa432008-02-08 00:56:02 +00004229
Christian Heimesf75dbef2008-02-08 00:11:31 +00004230- Fixed a minor memory leak in dictobject.c. The content of the free
4231 list was not freed on interpreter shutdown.
4232
Georg Brandl21e99f42010-03-07 15:23:59 +00004233- Limit free list of method and built-in function objects to 256

Christian Heimes6075a822008-02-06 12:44:34 +00004235
Georg Brandl3ee81df2008-05-17 18:14:43 +00004236- Patch #1953: Added ``sys._compact_freelists()`` and the C API
4237 functions ``PyInt_CompactFreeList`` and ``PyFloat_CompactFreeList``
Christian Heimes422051a2008-02-04 18:00:12 +00004238 to compact the internal free lists of pre-allocted ints and floats.
4239
Georg Brandl3ee81df2008-05-17 18:14:43 +00004240- Issue #1983: Fixed return type of fork(), fork1() and forkpty()
4241 calls. Python expected the return type int but the fork familie
4242 returns pi_t.
Christian Heimes951cc0f2008-01-31 23:08:23 +00004243

4254 the internal lookup cache for ref leak tests.
Christian Heimes908caac2008-01-27 23:34:59 +00004255
Georg Brandl3ee81df2008-05-17 18:14:43 +00004256- Patch #1473257: generator objects gain a gi_code attribute. This is
4257 the same object as the func_code attribute of the function that
4258 produced the generator.
Georg Brandl0cdf9a32008-01-26 14:14:20 +00004259
Georg Brandl3ee81df2008-05-17 18:14:43 +00004260- Issue #1920: "while 0" statements were completely removed by the
4261 compiler, even in the presence of an "else" clause, which is
4262 supposed to be run when the condition is false. Now the compiler
4263 correctly emits bytecode for the "else" suite.
Amaury Forgeot d'Arc31eaafe2008-01-24 22:59:25 +00004264
Guido van Rossumeead05f2008-01-24 18:21:02 +00004265- A few crashers fixed: weakref_in_del.py (issue #1377858);
4266 loosing_dict_ref.py (issue #1303614, test67.py);
4267 borrowed_ref_[34].py (not in tracker).
4268
Vinay Sajipd7cf32e2008-01-24 12:43:33 +00004269- Issue #1069410: The "can't load dll" message box on Windows is
Christian Heimesb2302ba2008-01-23 17:15:06 +00004270 suppressed while an extension is loaded by calling SetErrorMode in

4272
Georg Brandl3ee81df2008-05-17 18:14:43 +00004273- Issue #1915: Python compiles with --enable-unicode=no again. However
Christian Heimes082c9b02008-01-23 14:20:50 +00004274 several extension methods and modules do not work without unicode
4275 support.
4276
Georg Brandl26543b12008-01-21 18:36:51 +00004277- Issue #1882: when compiling code from a string, encoding cookies in the

4279
Georg Brandl14404b62008-01-19 19:27:05 +00004280- Issue #1679: "0x" was taken as a valid integer literal.
4281
Georg Brandl6caad7d2008-01-26 14:19:22 +00004282- Issue #1865: ``bytes`` as an alias for ``str`` and b"" as an alias "" were
Christian Heimes288e89a2008-01-18 18:24:07 +00004283 added.
4284
Christian Heimesc94e2b52008-01-14 04:13:37 +00004285- sys.float_info / PyFloat_GetInfo: The floating point information
4286 object was converted from a dict to a specialized structseq object.
4287
Georg Brandl3ee81df2008-05-17 18:14:43 +00004288- Patch #1816: Added sys.flags structseq. It exposes the status of
4289 most command line arguments and PYTHON* environment variables.
Christian Heimesf31b69f2008-01-14 03:42:48 +00004290
Georg Brandl3ee81df2008-05-17 18:14:43 +00004291- Objects/structseq.c: Implemented new structseq representation. The

Georg Brandl3ee81df2008-05-17 18:14:43 +00004295- Patch #1700288: added a type attribute cache that caches method
4296 accesses, resulting in speedups in heavily object-oriented code.
Amaury Forgeot d'Arce4c270c2008-01-14 00:29:41 +00004297
Neal Norwitz3fc15b82008-01-10 05:42:58 +00004298- Bug #1776: __import__() no longer accepts filenames on any platform.
4299 The first parameter to __import__() must be a valid module name.

Georg Brandlaed6c662008-01-07 17:25:53 +00004301- Patch #1668: renamed THREADDEBUG envvar to PYTHONTHREADDEBUG.
4302
Georg Brandl3ee81df2008-05-17 18:14:43 +00004303- Patch #602345: Add -B command line option, PYTHONDONTWRITEBYTECODE
4304 envvar and sys.dont_write_bytecode attribute. All these can be set
4305 to forbid Python to attempt to write compiled bytecode files.
Georg Brandl2da0fce2008-01-07 17:09:35 +00004306
Georg Brandl3ee81df2008-05-17 18:14:43 +00004307- Improve some exception messages when Windows fails to load an
4308 extension module. Now we get for example '%1 is not a valid Win32
4309 application' instead of 'error code 193'.

Christian Heimes0a8143f2007-12-18 23:22:54 +00004316- Issue #1635: Platform independent creation and representation of NaN
Georg Brandl3ee81df2008-05-17 18:14:43 +00004317 and INF. float("nan"), float("inf") and float("-inf") now work on
4318 every platform with IEEE 754 semantics.

Georg Brandl3ee81df2008-05-17 18:14:43 +00004320- Compiler now generates simpler and faster code for dictionary
4321 literals. The oparg for BUILD_MAP now indicates an estimated
4322 dictionary size. There is a new opcode, STORE_MAP, for adding
4323 entries to the dictionary.

Georg Brandl3ee81df2008-05-17 18:14:43 +00004352- Patch #1739468: Directories and zipfiles containing a __main__.py
4353 file can now be directly executed by passing their name to the
4354 interpreter. The directory/zipfile is automatically inserted as the
4355 first entry in sys.path.

Georg Brandl3ee81df2008-05-17 18:14:43 +00004357- Issue #1265: Fix a problem with sys.settrace, if the tracing
4358 function uses a generator expression when at the same time the
4359 executed code is closing a paused generator.
Amaury Forgeot d'Arc0d75f092007-11-13 21:54:28 +00004360
Raymond Hettinger1760c8a2007-11-08 02:52:43 +00004361- sets and frozensets now have an isdisjoint() method.

4366
Georg Brandl21e99f42010-03-07 15:23:59 +00004367- The enumerate() built-in function is no longer bounded to sequences
Georg Brandl3ee81df2008-05-17 18:14:43 +00004368 smaller than LONG_MAX. Formerly, it raised an OverflowError. Now,
4369 automatically shifts from ints to longs.
Raymond Hettinger8f669372007-10-03 21:18:11 +00004370
Georg Brandl3ee81df2008-05-17 18:14:43 +00004371- Issue #1686386: Tuple's tp_repr did not take into account the
4372 possibility of having a self-referential tuple, which is possible
4373 from C code. Nor did object's tp_str consider that a type's tp_str
4374 could do something that could lead to an inifinite recursion.
4375 Py_ReprEnter() and Py_EnterRecursiveCall(), respectively, fixed the
4376 issues.
Brett Cannon0b14f242007-09-30 19:45:10 +00004377
Georg Brandl3ee81df2008-05-17 18:14:43 +00004378- Issue #1164: It was possible to trigger deadlock when using the
4379 'print' statement to write to a file since the GIL was not released
4380 as needed. Now PyObject_Print() does the right thing along with
4381 various tp_print implementations of the built-in types and those in
4382 the collections module.
Brett Cannon01531592007-09-17 03:28:34 +00004383
Georg Brandl3ee81df2008-05-17 18:14:43 +00004384- Issue #1147: Exceptions were directly allowing string exceptions in

4386 allowed.

Brett Cannona0c05512007-09-10 21:38:27 +00004390
Brett Cannon1e534b52007-09-07 04:18:30 +00004391- Issue #1202533: Fix infinite recursion calls triggered by calls to
Georg Brandl3ee81df2008-05-17 18:14:43 +00004392 PyObject_Call() never calling back out to Python code to trigger
4393 recursion depth updates/checks. Required the creation of a static
4394 RuntimeError instance in case normalizing an exception put the
4395 recursion check value past its limit. Fixes crashers
4396 infinite_rec_(1|2|4|5).py.
Brett Cannon1e534b52007-09-07 04:18:30 +00004397

Neal Norwitz0ac60192007-05-27 04:08:54 +00004411- Add new attribute names for function objects. All the func_* become
Georg Brandl3ee81df2008-05-17 18:14:43 +00004412 __*__ attributes. (Some already existed, e.g., __doc__ and
4413 __name__.)
Neal Norwitz0ac60192007-05-27 04:08:54 +00004414
Neal Norwitz8b2bfbc2007-05-23 06:35:32 +00004415- Add -3 option to the interpreter to warn about features that are
4416 deprecated and will be changed/removed in Python 3.0.
4417
Georg Brandl2134e752007-05-21 20:34:16 +00004418- Patch #1686487: you can now pass any mapping after '**' in function
4419 calls.
4420
Collin Winter62903052007-05-18 23:11:24 +00004421- except clauses may now be spelled either "except E, target:" or
Georg Brandl3ee81df2008-05-17 18:14:43 +00004422 "except E as target:". This is to provide forwards compatibility
4423 with Python 3.0.

Vinay Sajip8549ce32007-05-06 17:53:37 +00004430- When __slots__ are set to a unicode string, make it work the same as
Neal Norwitzcbd9ee62007-04-14 05:25:50 +00004431 setting a plain string, ie don't expand to single letter identifiers.
4432
Raymond Hettinger13936692007-04-11 18:40:58 +00004433- Request #1191699: Slices can now be pickled.
4434
Raymond Hettinger4db5fe92007-04-12 04:10:00 +00004435- Request #1193128: str.translate() now allows a None argument for
4436 translations that only remove characters without re-mapping the
4437 remaining characters.
4438
Georg Brandl5cb76c12007-03-21 09:00:39 +00004439- Patch #1682205: a TypeError while unpacking an iterable is no longer
4440 masked by a generic one with the message "unpack non-sequence".
4441
Neal Norwitzaa754b72007-03-21 06:39:48 +00004442- Remove unused file Python/fmod.c.
4443
Guido van Rossum143b5642007-03-23 04:58:42 +00004444- Bug #1683368: The object.__init__() and object.__new__() methods are
4445 now stricter in rejecting excess arguments. The only time when
4446 either allows excess arguments is when it is not overridden and the
4447 other one is. For backwards compatibility, when both are
4448 overridden, it is a deprecation warning (for now; maybe a Py3k
Guido van Rossum234b1ff2007-03-23 19:39:01 +00004449 warning later). Also, type.__init__() insists on the same signature
4450 as supported by type.__new__().
Guido van Rossum143b5642007-03-23 04:58:42 +00004451
Georg Brandl3ee81df2008-05-17 18:14:43 +00004452- Patch #1675423: PyComplex_AsCComplex() now tries to convert an
4453 object to complex using its __complex__() method before falling back
4454 to the __float__() method. Therefore, the functions in the cmath
4455 module now can operate on objects that define a __complex__()
4456 method.
Georg Brandl2b869942007-03-17 16:08:45 +00004457
Georg Brandl3ee81df2008-05-17 18:14:43 +00004458- Patch #1623563: allow __class__ assignment for classes with
4459 __slots__. The old and the new class are still required to have the
4460 same slot names.
Žiga Seilnacht6f2d09c2007-03-16 11:59:38 +00004461

4466 ``object.__reduce_ex__()`` is called with an object that is faking
4467 its type.

4473
Georg Brandl7b9c5552007-03-12 14:30:05 +00004474- Bug #1678647: write a newline after printing an exception in any
4475 case, even when converting the value to a string failed.
4476
Georg Brandl871f1bc2007-03-12 13:17:36 +00004477- The dir() function has been extended to call the __dir__() method on
Georg Brandl3ee81df2008-05-17 18:14:43 +00004478 its argument, if it exists. If not, it will work like before. This
4479 allows customizing the output of dir() in the presence of a
4480 __getattr__().

Collin Winter276887b2007-03-12 16:11:39 +00004482- Patch #922167: Python no longer segfaults when faced with infinitely
4483 self-recursive reload() calls (as reported by bug #742342).
4484
Georg Brandl3ee81df2008-05-17 18:14:43 +00004485- Patch #1675981: remove unreachable code from ``type.__new__()``

Georg Brandl3ee81df2008-05-17 18:14:43 +00004488- Patch #1491866: change the complex() constructor to allow
4489 parthensized forms. This means complex(repr(x)) now works instead of
4490 raising a ValueError.
Collin Wintere38051d2007-03-09 20:33:07 +00004491
Georg Brandlaa2321b2007-03-07 00:40:28 +00004492- Patch #703779: unset __file__ in __main__ after running a file. This
Georg Brandl3ee81df2008-05-17 18:14:43 +00004493 makes the filenames the warning module prints much more sensible
4494 when a PYTHONSTARTUP file is used.
Georg Brandlaa2321b2007-03-07 00:40:28 +00004495

4497 exception if the -i command line option or PYTHONINSPECT environment
Georg Brandl3ee81df2008-05-17 18:14:43 +00004498 variable is given, but break into the interactive interpreter just
4499 like on other exceptions or normal program exit.

Georg Brandl0fca97a2007-03-05 22:28:08 +00004507- Patch #1674228: when assigning a slice (old-style), check for the
4508 sq_ass_slice instead of the sq_slice slot.
4509
Georg Brandl3ee81df2008-05-17 18:14:43 +00004510- When printing an unraisable error, don't print exceptions. before
4511 the name. This duplicates the behavior whening normally printing
4512 exceptions.

Georg Brandl3ee81df2008-05-17 18:14:43 +00005045 AttributeError instead of an IOError when the server's response
5046 didn't contain a valid HTTP status line.
Georg Brandlf66b6032007-03-14 08:27:52 +00005047

5062
Georg Brandl3ee81df2008-05-17 18:14:43 +00005063- Patch #1530482: add pydoc.render_doc() which returns the

5078
Georg Brandl92a6bae2007-03-13 17:43:32 +00005079- Patch #1603688: ConfigParser.SafeConfigParser now checks values that
Georg Brandl3ee81df2008-05-17 18:14:43 +00005080 are set for invalid interpolation sequences that would lead to
5081 errors on reading back those values.

5124 returned string up to the first NUL character.

5135
Georg Brandl3ee81df2008-05-17 18:14:43 +00005136- unittest now verifies more of its assumptions. In particular,
5137 TestCase and TestSuite subclasses (not instances) are no longer
5138 accepted in TestSuite.addTest(). This should cause no
5139 incompatibility since it never made sense with ordinary subclasses
5140 -- the failure just occurred later, with a more cumbersome
5141 exception.

5512 complex, tuple, list, dict, set, and frozenset. Formerly, it would

Gregory P. Smithec10a4a2007-11-05 02:32:26 +00005529- pybsddb.sf.net Bug #477182: Load the database flags at database open
Georg Brandl3ee81df2008-05-17 18:14:43 +00005530 time so that opening a database previously created with the DB_DUP
5531 or DB_DUPSORT flag set will keep the proper behavior on subsequent
5532 opens. Specifically: dictionary assignment to a DB object will
5533 replace all values for a given key when the database allows
5534 duplicate values. DB users should use DB.put(k, v) when they want
5535 to store duplicates; not DB[k] = v.

5542 characters with ASCII value less than 32. Also, it correctly quotes
5543 dots only if they occur on a single line, as opposed to the previous
5544 behavior of quoting dots if they are the second character of any
5545 line.
