788 32-bit-only installer Pythons on systems with Xcode 4 (currently
789 OS X 10.8, 10.7, and optionally 10.6).
790 * Backport 3.3.0 fixes to 2.7 branch (for release in 2.7.4)
791 * Since Xcode 4 removes ppc support, extension module builds now
792 check for ppc compiler support and by default remove ppc and
793 ppc64 archs when they are not available.
794 * Extension module builds now revert to using system installed
795 headers and libs (/usr and /System/Library) if the SDK used
796 to build the interpreter is not installed or has moved.
797 * Try to avoid building extension modules with deprecated
798 and problematic Apple llvm-gcc compiler. If original compiler
799 is not available, use clang instead by default.

Ned Deily0d0ea482012-02-10 12:59:06 +01001140- Issue #13590: On OS X 10.7 and 10.6 with Xcode 4.2, building
1141 Distutils-based packages with C extension modules may fail because
1142 Apple has removed gcc-4.2, the version used to build python.org
1143 64-bit/32-bit Pythons. If the user does not explicitly override
1144 the default C compiler by setting the CC environment variable,
1145 Distutils will now attempt to compile extension modules with clang
1146 if gcc-4.2 is required but not found. Also as a convenience, if
1147 the user does explicitly set CC, substitute its value as the default
1148 compiler in the Distutils LDSHARED configuration variable for OS X.
1149 (Note, the python.org 32-bit-only Pythons use gcc-4.0 and the 10.4u
1150 SDK, neither of which are available in Xcode 4. This change does not
1151 attempt to override settings to support their use with Xcode 4.)

Ned Deily87e82bb2011-06-28 19:52:59 -07001424- Issue #9516: On Mac OS X, change Distutils to no longer globally attempt to
1425 check or set the MACOSX_DEPLOYMENT_TARGET environment variable for the
1426 interpreter process. This could cause failures in non-Distutils subprocesses
1427 and was unreliable since tests or user programs could modify the interpreter
Ezio Melotti302ad8d2013-01-19 19:44:58 +02001428 environment after Distutils set it. Instead, have Distutils set the
Ned Deily87e82bb2011-06-28 19:52:59 -07001429 deployment target only in the environment of each build subprocess. It is
1430 still possible to globally override the default by setting
1431 MACOSX_DEPLOYMENT_TARGET before launching the interpreter; its value must be
1432 greater or equal to the default value, the value with which the interpreter
1433 was built.

Raymond Hettinger20397532010-09-12 02:11:45 +00002417- Issue #9825: removed __del__ from the definition of collections.OrderedDict.
2418 This prevents user-created self-referencing ordered dictionaries from
2419 becoming permanently uncollectable GC garbage. The downside is that
2420 removing __del__ means that the internal doubly-linked list has to wait for
2421 GC collection rather than freeing memory immediately when the refcnt drops
2422 to zero.

2430 to fetch the original errno, or to filter timeout errors. Now the
2431 original error is re-raised.

2452
R. David Murray7c4bf552010-08-25 01:45:57 +00002453- Issue #1194222: email.utils.parsedate now returns RFC2822 compliant four
2454 character years even if the message contains RFC822 two character years.
2455
Daniel Stutzbach91287322010-08-24 21:09:30 +00002456- Issue #8750: Fixed MutableSet's methods to correctly handle

2469
Antoine Pitrou3ebaed62010-08-21 19:17:25 +00002470- Issue #9617: Signals received during a low-level write operation aren't
2471 ignored by the buffered IO layer anymore.
2472
Benjamin Peterson52c36052010-08-21 03:03:22 +00002473- Issue #2521: Use weakrefs on for caching in the abc module, so that classes

2475
Raymond Hettingera54b2da2010-08-17 19:03:06 +00002476- Issue #9626: the view methods for collections.OrderedDict() were returning
2477 the unordered versions inherited from dict. Those methods are now
2478 overridden to provide ordered views.

2482 without this marker will not be overwritten or removed.
2483
Antoine Pitroue1436d12010-08-12 15:25:51 +00002484- Issue #7467: when reading a file from a ZIP archive, its CRC is checked
2485 and a BadZipfile error is raised if it doesn't match (as used to be the
2486 case in Python 2.5 and earlier).
2487
Antoine Pitroucb4f47c2010-08-11 13:40:17 +00002488- Issue #9550: a BufferedReader could issue an additional read when the
2489 original read request had been satisfied, which could block indefinitely
2490 when the underlying raw IO channel was e.g. a socket. Report and original
2491 patch by Jason V. Miller.
2492
Fred Drake0a1fa0e2010-08-10 13:09:54 +00002493- Issue #9551: Don't raise TypeError when setting the value to None for

2885 replaces with U+FFFD only the start byte ('\xf1') and the continuation byte
2886 ('\x80') even if '\xf1' is the start byte of a 4-bytes sequence.
2887 Previous versions returned a single u'\ufffd'.

2897 (2**53+1 == complex(2**53) == 2**53), breaking transivity of equality.

Georg Brandlfee0f442010-05-22 21:26:21 +00003141- Issue #2302: Fix a race condition in SocketServer.BaseServer.shutdown, where
3142 the method could block indefinitely if called just before the event loop

Antoine Pitroufc69af12010-04-24 20:04:58 +00003146- Issue #5103: SSL handshake would ignore the socket timeout and block
3147 indefinitely if the other end didn't respond.
3148
Georg Brandlfee0f442010-05-22 21:26:21 +00003149- The do_handshake() method of SSL objects now adjusts the blocking mode of the

3161 string "python" as the *ident*. openlog() arguments are all optional and
3162 keywords.

Mark Dickinsond2f3e3f2010-05-05 22:23:58 +00003242 (Optimization was unintentionally turned on in gcc --with-pydebug builds in

Philip Jenveyaebbaeb2010-04-06 23:24:45 +00003267- Issue #7301: Add environment variable $PYTHONWARNINGS.
3268
Benjamin Peterson3a1dfa22010-04-06 21:50:00 +00003269- Issue #8329: Don't return the same lists from select.select when no fds are
3270 changed.
3271
Georg Brandlfee0f442010-05-22 21:26:21 +00003272- Issue #8259: ``1L << (2**31)`` no longer produces an 'outrageous shift error'
Mark Dickinson82791672010-04-06 16:47:55 +00003273 on 64-bit machines. The shift count for either left or right shift is
3274 permitted to be up to sys.maxsize.
3275
Benjamin Peterson4ceeeb02010-04-03 22:48:51 +00003276- Ensure that tokenization of identifiers is not affected by locale.

Georg Brandlfee0f442010-05-22 21:26:21 +00003282- Issue #7994: Issue a PendingDeprecationWarning if object.__format__ is called
3283 with a non-empty format string. This is an effort to future-proof user
3284 code. If a derived class does not currently implement __format__ but later
3285 adds its own __format__, it would most likely break user code that had
Antoine Pitrou01a196a2011-01-02 20:05:11 +00003286 supplied a format string. This will be changed to a DeprecationWarning in
Georg Brandlfee0f442010-05-22 21:26:21 +00003287 Python 3.3 and it will be an error in Python 3.4.

Georg Brandlfee0f442010-05-22 21:26:21 +00003320- Issue #8257: The Decimal construct now accepts a float instance directly,
3321 converting that float to a Decimal of equal value:
Mark Dickinson8a950712010-04-03 15:47:46 +00003322

Georg Brandlfee0f442010-05-22 21:26:21 +00003337- Issue #7279: Comparisons involving a Decimal signaling NaN now signal
3338 InvalidOperation instead of returning False. (Comparisons involving a quiet
3339 NaN are unchanged.) Also, Decimal quiet NaNs are now hashable; Decimal
3340 signaling NaNs remain unhashable.
Mark Dickinsone096e822010-04-02 10:17:07 +00003341
Georg Brandlfee0f442010-05-22 21:26:21 +00003342- Issue #2531: Comparison operations between floats and Decimal instances now
3343 return a result based on the numeric values of the operands; previously they
3344 returned an arbitrary result based on the relative ordering of id(float) and
3345 id(Decimal).

Georg Brandlfee0f442010-05-22 21:26:21 +00003359- Comparisons using one of <, <=, >, >= between a complex instance and a
3360 Fractions instance now raise TypeError instead of returning True/False. This
3361 makes Fraction <=> complex comparisons consistent with int <=> complex, float
3362 <=> complex, and complex <=> complex comparisons.

Georg Brandlba83f822010-03-14 09:50:54 +00003780 file position when calling `truncate()`. It would previously change the file
3781 position to the given argument, which goes against the tradition of
Antoine Pitrouf3fa0742010-01-31 22:26:04 +00003782 ftruncate() and other truncation APIs. Patch by Pascal Chambon.
3783

3785 class used to represent files stored inside an archive. The new
3786 implementation is significantly faster and can be wrapped in a
3787 ``io.BufferedReader`` object for more speedups. It also solves an issue
3788 where interleaved calls to ``read()`` and ``readline()`` give wrong results.

3878
Georg Brandlba83f822010-03-14 09:50:54 +00003879- The ``__complex__()`` method is now looked up on the class of instances to
3880 make it consistent with other special methods.

3884
Mark Dickinson1b34d252010-01-01 17:27:30 +00003885- Issue #5080: A number of functions and methods previously produced a
Georg Brandlba83f822010-03-14 09:50:54 +00003886 DeprecationWarning when passed a float argument where an integer was expected.
3887 These functions and methods now raise TypeError instead. The majority of the
3888 effects of this change are in the extension modules, but some core functions
3889 and methods are affected: notably the 'chr', 'range' and 'xrange' builtins,
3890 and many unicode/str methods.

3902
Georg Brandlba83f822010-03-14 09:50:54 +00003903- Issue #1811: Improve accuracy and cross-platform consistency for true division
3904 of integers: the result of a/b is now correctly rounded for ints a and b (at
3905 least on IEEE 754 platforms), and in particular does not depend on the
3906 internal representation of a long.

3914
Georg Brandlba83f822010-03-14 09:50:54 +00003915 These executables now work properly with the arch(1) command: ``arch -ppc
3916 python`` will start a universal binary version of python in PPC mode (unlike

Georg Brandlba83f822010-03-14 09:50:54 +00004080- Issue #7117: On almost all platforms: float-to-string and string-to-float
4081 conversions within Python are now correctly rounded. Places these conversions
4082 occur include: str for floats and complex numbers; the float and complex
4083 constructors; old-style and new-style numeric formatting; serialization and
4084 deserialization of floats and complex numbers using marshal, pickle and json;
4085 parsing of float and imaginary literals in Python code; Decimal-to-float
4086 conversion.
Mark Dickinsonb678de82009-11-19 18:41:49 +00004087
Georg Brandlba83f822010-03-14 09:50:54 +00004088 The conversions use a Python-adapted version of David Gay's well-known dtoa.c,
4089 providing correctly-rounded strtod and dtoa C functions. This code is
4090 supported on Windows, and on Unix-like platforms using gcc, icc or suncc as
4091 the C compiler. There may be a small number of platforms on which correct
4092 operation of this code cannot be guaranteed, so the code is not used: notably,
4093 this applies to platforms where the C double format is not IEEE 754 binary64,
4094 and to platforms on x86 hardware where the x87 FPU is set to 64-bit precision
4095 and Python's configure script is unable to determine how to change the FPU
4096 precision. On these platforms conversions use the platform strtod and dtoa,
4097 as before.

Georg Brandlba83f822010-03-14 09:50:54 +00004099- Issue #7117: Backport round implementation from Python 3.x. ``round()`` now
4100 uses the correctly-rounded string <-> float conversions described above (when
4101 available), and so produces correctly rounded results that will display nicely
4102 under the float repr. There are two related small changes: (1) round now
4103 accepts any class with an ``__index__()`` method for its second argument (but
4104 no longer accepts floats for the second argument), and (2) an excessively
4105 large second integer argument (e.g., ``round(1.234, 10**100)``) no longer
4106 raises an exception.

5688 'b', 'B', 'h', 'H', 'i', 'l', '*b', '*h' ,'*i', '*l', and an x with a
5689 __long__ method could be packed by 'q', 'Q', '*q', '*Q'; for x with
5690 neither __int__ nor __long__, TypeError used to be raised (with a
5691 confusing error message) for 'I', 'L', '*B', '*H', '*I', '*L', and
5692 struct.error in other cases.

5695 argument with an __int__ method can be packed, but use of this feature

Amaury Forgeot d'Arc05e34492008-09-10 22:04:45 +00005889- Issue #3743: In a few places, PY_FORMAT_SIZE_T was incorrectly used with
5890 PyString_FromFormat or PyErr_Format to display size_t values. The macro
5891 PY_FORMAT_SIZE_T is designed to select the correct format for the OS
5892 ``printf`` function, whereas PyString_FromFormat has an independent
5893 implementation and uses "%zd" on all platforms for size_t values.
5894 This makes a difference on win64, where ``printf`` needs "%Id" to display
5895 64bit values.

5901 object; previously an int would be returned for small values. the __long__
5902 method is allowed to return either an int or a long, but the behaviour of

Antoine Pitroud4ae97b2008-08-29 18:39:48 +00005912 was correctly parsed but parsing of subsequent arguments failed.
5913
Vinay Sajip35e3b032008-09-01 14:33:59 +00005914- Issue #2534: speed up isinstance() and issubclass() by 50-70%, so as to
Antoine Pitrou0668c622008-08-26 22:42:08 +00005915 match Python 2.5 speed despite the __instancecheck__ / __subclasscheck__
5916 mechanism. In the process, fix a bug where isinstance() and issubclass(),
5917 when given a tuple of classes as second argument, were looking up
5918 __instancecheck__ / __subclasscheck__ on the tuple rather than on each
5919 type object.

Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00006058What's New in Python 2.6 beta 3?
6059================================
6060
Barry Warsaw07a4a382008-08-21 01:15:08 +00006061*Release date: 20-Aug-2008*
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00006062
6063Core and Builtins
6064-----------------
6065
Guido van Rossumf8402962008-08-20 15:01:50 +00006066- Issue #1878: Remove Py_TPFLAGS_HAVE_VERSION_TAG from
6067 Py_TPFLAGS_DEFAULT when not building the core. This means 3rd party
6068 extensions do not automatically benefit from the class attribute
6069 cache; they will have to explicitly add Py_TPFLAGS_HAVE_VERSION_TAG
6070 to their tp_flags field if they care. This is a backwards
6071 compatibility feature; in 3.0, all types will use the cache by
6072 default.
6073
Benjamin Petersonf647dc12008-08-20 01:27:30 +00006074- Keyword arguments can now follow starred arguments. (``f(a, *args,
6075 keyword=23)`` is now valid syntax.)
6076
Thomas Heller0ad5ae02008-08-19 19:25:04 +00006077- ctypes function pointers that are COM methods have a boolean True
6078 value again.
6079
Martin v. Löwisf91d46a2008-08-12 14:49:50 +00006080- Issue #3139: Make buffer-interface thread-safe wrt. PyArg_ParseTuple,
6081 by denying s# to parse objects that have a releasebuffer procedure,
6082 and introducing s*.
6083
Georg Brandl1e13ea92008-08-11 09:07:59 +00006084- Issue #3537: Fix an assertion failure when an empty but presized dict
6085 object was stored in the freelist.
6086
Mark Dickinsonb6467572008-08-04 21:30:09 +00006087- Issue #1481296: Make long(float('nan')) and int(float('nan')) raise
6088 ValueError consistently across platforms.
6089
Amaury Forgeot d'Arc39fd6722008-07-31 21:28:03 +00006090- Issue #3479: On platforms where sizeof(int) is smaller than sizeof(long)
6091 (64bit Unix, for example), unichr() would truncate its argument and return
6092 u'\x00' for unichr(2**32). Now it properly raises an OverflowError.
6093
Neal Norwitze7d8be82008-07-31 17:17:14 +00006094- Apply security patches from Apple.
6095
Amaury Forgeot d'Arc246daed2008-07-31 00:42:16 +00006096- Issue #2542: Now that issubclass() may call arbitrary code, ensure that
6097 PyErr_ExceptionMatches returns 0 when an exception occurs there.
6098
Antoine Pitrou92f82162008-07-25 22:22:08 +00006099- Issue #1819: function calls with several named parameters are now on
6100 average 35% faster (as measured by pybench).
6101
Amaury Forgeot d'Arce4921fe2008-07-21 22:00:38 +00006102- Issue #2378: An unexpected UnboundLocalError or NameError could appear when
6103 the python debugger steps into a class statement: the free variables (local
6104 variables defined in an outer scope) would be deleted from the outer scope.
6105
Gregory P. Smith0470bab2008-07-22 04:46:32 +00006106- Issue #2620: Overflow checking when allocating or reallocating memory
6107 was not always being done properly in some python types and extension
6108 modules. PyMem_MALLOC, PyMem_REALLOC, PyMem_NEW and PyMem_RESIZE have
6109 all been updated to perform better checks and places in the code that
6110 would previously leak memory on the error path when such an allocation
6111 failed have been fixed.

6114-------
6115
Hirokazu Yamamoto838c79f2008-08-20 13:14:07 +00006116- Issue #3612: Added some missing basic types in ctypes.wintypes.
6117
Benjamin Petersone977ad42008-08-20 01:42:01 +00006118- The methods ``is_in_tuple()``, ``is_vararg()``, and ``is_keywordarg()`` of
6119 symtable.Symbol have been deprecated for removal in 3.0 and the next release.
6120
Amaury Forgeot d'Arc351ffb82008-08-18 19:23:47 +00006121- Issue #2234: distutils failed for some versions of the cygwin compiler. The
6122 version reported by these tools does not necessarily follow the python
6123 version numbering scheme, so the module is less strict when parsing it.
6124
Nick Coghlanf70385a2008-08-18 12:42:46 +00006125- Issue #2235: Added Py3k warnings for types which will become unhashable
6126 under the stricter __hash__ inheritance rules in 3.0. Several types
6127 which did not meet the rules for hash invariants and were already
6128 unhashable in 3.0 have now been explicitly flagged as unhashable in
6129 2.6 as well (collections.Mapping, collections.Set, unittest.TestSuite,
6130 xml.dom.minidom.NamedNodeMap, numbers.Number, UserList.UserList)
6131
Brett Cannon88f801d2008-08-18 00:46:22 +00006132- Update __all__ for cookielib, csv, os, urllib2, and weakref to include things
6133 imported into the module but exposed as part of the module's API.
6134
Brett Cannon7b96f072008-08-18 00:41:11 +00006135- Remove an unneeded import of abc.ABCMeta from 'inspect'.
6136
Brett Cannon46225e72008-08-18 00:36:52 +00006137- Remove unneeded imports of 'sys' and 'warnings' from 'io'.

Brett Cannon25c9d6a2008-08-17 22:10:11 +00006139- Remove unneeded imports of 'warnings' from shelve, filecmp, and dummy_thread.
6140
Hirokazu Yamamoto41a81eb2008-08-17 13:10:46 +00006141- Issue #3575: Incremental decoder's decode function now takes bytearray
6142 by using 's*' instead of 't#'.
6143
Mark Dickinson3e4caeb2009-02-21 20:27:01 +00006144- Issue #2222: Fixed reference leak when occurred os.rename()
Hirokazu Yamamoto7f30a682008-08-17 09:46:56 +00006145 fails unicode conversion on 2nd parameter. (windows only)
6146
Georg Brandl222e2082010-08-01 22:27:39 +00006147- Issue #2464: urllib2 now supports a malformation in the URL received
Facundo Batista94f243a2008-08-17 03:38:39 +00006148 in a redirect.
6149
Brett Cannonabe423e2008-08-16 21:47:07 +00006150- Silence the DeprecationWarning raised when importing mimetools in
Brett Cannon721b1452008-08-16 22:00:27 +00006151 BaseHTTPServer, cgi (and rfc822), httplib.
Brett Cannonabe423e2008-08-16 21:47:07 +00006152
Facundo Batistaeb90b782008-08-16 14:44:07 +00006153- Issue #2776: fixed small issue when handling an URL with double slash
6154 after a 302 response in the case of not going through a proxy.
6155
Antoine Pitroub90a8be2008-08-15 21:03:21 +00006156- Issue #2676: in the email package, content-type parsing was hanging on
6157 pathological input because of quadratic or exponential behaviour of a
6158 regular expression.
6159
Antoine Pitrou11ec65d2008-08-14 21:04:30 +00006160- Issue #3476: binary buffered reading through the new "io" library is now
6161 thread-safe.
6162
Brett Cannonbf3157b2008-08-14 05:00:03 +00006163- Silence the DeprecationWarning of rfc822 when it is imported by mimetools
6164 since mimetools itself is deprecated. Because modules are cached, all
6165 subsequent imports of rfc822 will not raise a visible DeprecationWarning.
6166
Antoine Pitrou9fcd4b32008-08-11 17:21:36 +00006167- Issue #3134: shutil referenced undefined WindowsError symbol.
6168
Robert Schuppenies14646332008-08-10 11:01:53 +00006169- Issue #1342811: Fix leak in Tkinter.Menu.delete. Commands associated to
6170 menu entries were not deleted.
6171
Brett Cannon83e81842008-08-09 23:30:55 +00006172- Copied the implementation of reduce() to _functools.reduce() to have a
6173 version that did not raise a DeprecationWarning under -3.
6174
Antoine Pitrou76b8bee2008-08-09 17:27:23 +00006175- Issue #3205: When iterating over a BZ2File fails allocating memory, raise
6176 a MemoryError rather than silently stop the iteration.
6177
Guido van Rossum59ce9012008-08-09 14:55:34 +00006178- Issue #3487: sre "bytecode" validator. Passing invalid "re-bytecode"
6179 to _sre.compile() will now be rejected. This should not affect anybody
6180 since the re.compile() function never generates invalid re-bytecode.
6181
Skip Montanaroa032bf42008-08-08 22:52:51 +00006182- Issue #3436: Make csv.DictReader's fieldnames attribute a property so that
6183 upon first access it can be automatically initialized from the csv file if
6184 it wasn't initialized during instantiation.
6185
Brett Cannon3aa2a492008-08-06 22:28:09 +00006186- Issue #2338: Create imp.reload() to help with transitioning to Python 3.0 as
6187 the reload() built-in has been removed.
6188
Brett Cannon7e30b672008-08-04 21:52:25 +00006189- Changed code in the following modules/packages to remove warnings raised
Brett Cannonc1b76e42008-08-09 23:06:16 +00006190 while running under the ``-3`` flag: aifc, asynchat, asyncore, bdb, bsddb,

Antoine Pitroude781a42008-08-09 12:43:23 +00006201 asking for a specific length. This problem only affected files opened
6202 using the new "io" module, not the built-in open() function.
Benjamin Peterson01a24322008-07-28 23:35:27 +00006203

Raymond Hettingere3ae6552008-06-20 04:18:15 +00006252What's New in Python 2.6 beta 2?
6253================================
6254
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00006255*Release date: 17-Jul-2008*
6256
Raymond Hettingere3ae6552008-06-20 04:18:15 +00006257Core and Builtins
6258-----------------
6259
Georg Brandl3e483f62008-07-16 22:57:41 +00006260- Issue #3156: Fix inconsistent behavior of the bytearray type: all
6261 its methods now allow for items objects that can be converted to
6262 an integer using operator.index().
6263
Mark Dickinson64b7e502008-07-16 09:40:03 +00006264- Issue #3360: Fix incorrect parsing of '020000000000.0', which
6265 produced a ValueError instead of giving the correct float.
6266
Eric Smitha5fa5a22008-07-16 00:11:49 +00006267- Issue #3083: Add alternate (#) formatting for bin, oct, hex output
6268 for str.format(). This adds the prefix 0b, 0o, or 0x, respectively.
6269
Mark Dickinson7103aa42008-07-15 19:08:33 +00006270- Issue #3008: the float type has a new instance method 'float.hex'
6271 and a new class method 'float.fromhex' to convert floating-point
6272 numbers to and from hexadecimal strings, respectively.
6273
Nick Coghlan6d6bd442008-07-15 15:40:22 +00006274- Issue #2235: __hash__ is once again inherited by default. To allow
6275 collections.Hashable to remain meaningful in the presence of the
6276 default hash implementation (object.__hash__), it is now possible
6277 to explicit block inheritance of hash by setting __hash__=None at
6278 the Python level, or tp_hash=PyObject_HashNotImplemented at the C
6279 level.
6280
Nick Coghlanb028f502008-07-13 14:52:36 +00006281- Issue #3221: Issue a RuntimeWarning instead of raising SystemError if
6282 the parent module cannot be found while performing an absolute import.
6283 This means that an incorrectly defined __package__ attribute will
6284 now only prevent relative imports in that module rather than causing
6285 all imports from that module to fail.
6286
Nick Coghlan14ff9942008-07-08 14:21:42 +00006287- Issue #2517: Allow unicode messages in Exceptions again by correctly
6288 bypassing the instance dictionary when looking up __unicode__ on
6289 new-style classes.
6290
Amaury Forgeot d'Arcbdd941f2008-07-01 20:38:04 +00006291- Issue #3242: Fix a crash inside the print statement, if sys.stdout is
6292 set to a custom object whose write() method happens to install
6293 another file in sys.stdout.
6294
Amaury Forgeot d'Arc1f40c8a2008-06-30 22:42:40 +00006295- Issue #3088: Corrected a race condition in classes derived from
6296 threading.local: the first member set by a thread could be saved in
6297 another thread's dictionary.
6298
Mark Dickinson1ec2fcd2008-06-20 14:53:43 +00006299- Issue #3004: Minor change to slice.indices(): the start and stop
6300 arguments are now treated identically, making the behaviour easier
6301 to describe and understand. For example, slice(None, -10,
6302 1).indices(9) now returns (0, 0, 1) instead of (0, -1, 1), and
6303 slice(None, 10, -1).indices(10) returns (9, 9, -1) instead of (9,
6304 10, -1).
6305
Georg Brandl278fc502008-07-19 12:46:12 +00006306- Issue #3219: Calling a function with repeated keyword arguments,
6307 f(a=2, a=23), would not cause a syntax error. This was a regression
6308 from 2.4 caused by the switch to the new compiler.
Benjamin Peterson175e4d92008-07-01 19:34:52 +00006309
Georg Brandl278fc502008-07-19 12:46:12 +00006310- Issue #2862: Make int and float freelist management consistent with
6311 other freelists. Changes their CompactFreeList apis into
6312 ClearFreeList apis and calls them via gc.collect().

Thomas Heller57adf222008-08-14 19:10:48 +00006317- Issue #3554: ctypes.string_at and ctypes.wstring_at did call Python
6318 api functions without holding the GIL, which could lead to a fatal
6319 error when they failed.
6320
Martin v. Löwisaabf4042008-08-02 07:20:25 +00006321- Issue #799428: Fix Tkinter.Misc._nametowidget to unwrap Tcl command objects.

6330 ForkingPickler.register() to resolve conflict with ctypes.
6331
Vinay Sajip51e65192008-07-18 09:01:10 +00006332- Issue #3090: Fixed ARCHFLAGS parsing on OS/X
Jesse Noller13e9d582008-07-16 14:32:36 +00006333
Thomas Heller880f5292008-07-15 19:39:38 +00006334- Issue #3313: Fixed a crash when a failed dlopen() call does not set

Raymond Hettinger3cd1e422008-07-10 14:03:19 +00006345
Amaury Forgeot d'Arc0f7cddc2008-07-06 21:34:39 +00006346- Issue #839496: SimpleHTTPServer used to open text files in text mode. This is
6347 both unnecessary (HTTP allows text content to be sent in several forms) and
Andrew M. Kuchlingcc3f2b12008-07-10 14:43:31 +00006348 wrong because the actual transmitted size could differ from the
Amaury Forgeot d'Arc0f7cddc2008-07-06 21:34:39 +00006349 content-length. The problem had been corrected in the 2.4 branch, but never
6350 merged into trunk.
6351
Georg Brandle78fbcc2008-07-05 10:13:36 +00006352- Issue #2663: add filtering capability to shutil.copytree().

Nick Coghlanc060b0e2008-07-02 13:09:19 +00006365- Issue #3190: Pydoc now hides the automatic module attribute __package__ (the
6366 handling is now the same as that of other special attributes like __name__).
6367
Brett Cannon8bb8fa52008-07-02 01:57:08 +00006368- Issue #2885 (partial): The urllib.urlopen() function has been deprecated for

6825 not called by default for backwards-compatibility reasons. Setting
6826 ``warnings.showwarning()`` to an implementation that lacks support

Georg Brandl3ee81df2008-05-17 18:14:43 +00006890- Issue #2550: The approach used by client/server code for obtaining
6891 ports to listen on in network-oriented tests has been refined in an
6892 effort to facilitate running multiple instances of the entire
6893 regression test suite in parallel without issue.
6894 test_support.bind_port() has been fixed such that it will always
6895 return a unique port -- which wasn't always the case with the
6896 previous implementation, especially if socket options had been set
6897 that affected address reuse (i.e. SO_REUSEADDR, SO_REUSEPORT). The
6898 new implementation of bind_port() will actually raise an exception
6899 if it is passed an AF_INET/SOCK_STREAM socket with either the
6900 SO_REUSEADDR or SO_REUSEPORT socket option set. Furthermore, if
6901 available, bind_port() will set the SO_EXCLUSIVEADDRUSE option on
6902 the socket it's been passed. This currently only applies to
6903 Windows. This option prevents any other sockets from binding to the
6904 host/port we've bound to, thus removing the possibility of the
6905 'non-deterministic' behaviour, as Microsoft puts it, that occurs
6906 when a second SOCK_STREAM socket binds and accepts to a host/port
6907 that's already been bound by another socket. The optional preferred
6908 port parameter to bind_port() has been removed. Under no
6909 circumstances should tests be hard coding ports!
6910
6911 test_support.find_unused_port() has also been introduced, which will
6912 pass a temporary socket object to bind_port() in order to obtain an
6913 unused port. The temporary socket object is then closed and
6914 deleted, and the port is returned. This method should only be used
6915 for obtaining an unused port in order to pass to an external program
6916 (i.e. the -accept [port] argument to openssl's s_server mode) or as
6917 a parameter to a server-oriented class that doesn't give you direct
6918 access to the underlying socket used.
6919
6920 Finally, test_support.HOST has been introduced, which should be used
6921 for the host argument of any relevant socket calls (i.e. bind and
6922 connect).
Trent Nelsone41b0062008-04-08 23:47:30 +00006923
6924 The following tests were updated to following the new conventions:
Georg Brandl3ee81df2008-05-17 18:14:43 +00006925 test_socket, test_smtplib, test_asyncore, test_ssl, test_httplib,

6927 test_asynchat and test_socket_ssl.
6928
Georg Brandl3ee81df2008-05-17 18:14:43 +00006929 It is now possible for multiple instances of the regression test
6930 suite to run in parallel without issue.

Eric Smitha73fbe72008-02-23 03:09:44 +00007209- Added the future_builtins module, which contains hex() and oct().
7210 These are the PEP 3127 version of these functions, designed to be
7211 compatible with the hex() and oct() builtins from Python 3.0. They
7212 differ slightly in their output formats from the existing, unchanged
7213 Python 2.6 builtins. The expected usage of the future_builtins
7214 module is:
7215 from future_builtins import hex, oct
7216
Eric Smith7ef40bf2008-02-20 23:34:22 +00007217- Issue #1600: Modifed PyOS_ascii_formatd to use at most 2 digit
7218 exponents for exponents with absolute value < 100. Follows C99
7219 standard. This is a change on Windows, which would use 3 digits.
7220 Also, added 'n' to the formats that PyOS_ascii_formatd understands,
7221 so that any alterations it does to the resulting string will be
7222 available in stringlib/formatter.h (for float.__format__).
7223
Eric Smith5a3c1352008-02-19 13:21:56 +00007224- Implemented PEP 3101, Advanced String Formatting. This adds a new
7225 builtin format(); a format() method for str and unicode; a
7226 __format__() method to object, str, unicode, int, long, float, and
7227 datetime; the class string.Formatter; and the C API
7228 PyObject_Format().
7229
Georg Brandl3ee81df2008-05-17 18:14:43 +00007230- Fixed several potential crashes, all caused by specially crafted
7231 __del__ methods exploiting objects in temporarily inconsistent
7232 state.

Georg Brandl3ee81df2008-05-17 18:14:43 +00007275- Patch #1473257: generator objects gain a gi_code attribute. This is
7276 the same object as the func_code attribute of the function that
7277 produced the generator.
Georg Brandl0cdf9a32008-01-26 14:14:20 +00007278
Georg Brandl3ee81df2008-05-17 18:14:43 +00007279- Issue #1920: "while 0" statements were completely removed by the
7280 compiler, even in the presence of an "else" clause, which is
7281 supposed to be run when the condition is false. Now the compiler
7282 correctly emits bytecode for the "else" suite.

7306
Georg Brandl3ee81df2008-05-17 18:14:43 +00007307- Patch #1816: Added sys.flags structseq. It exposes the status of
7308 most command line arguments and PYTHON* environment variables.
Christian Heimesf31b69f2008-01-14 03:42:48 +00007309
Georg Brandl3ee81df2008-05-17 18:14:43 +00007310- Objects/structseq.c: Implemented new structseq representation. The
7311 patch makes structseqs (e.g. the return value of os.stat) more
7312 readable.
Christian Heimes9c201962008-01-14 03:33:52 +00007313
Georg Brandl3ee81df2008-05-17 18:14:43 +00007314- Patch #1700288: added a type attribute cache that caches method
7315 accesses, resulting in speedups in heavily object-oriented code.
Amaury Forgeot d'Arce4c270c2008-01-14 00:29:41 +00007316
Neal Norwitz3fc15b82008-01-10 05:42:58 +00007317- Bug #1776: __import__() no longer accepts filenames on any platform.
7318 The first parameter to __import__() must be a valid module name.
Christian Heimes3403f152008-01-09 19:56:33 +00007319
Georg Brandlaed6c662008-01-07 17:25:53 +00007320- Patch #1668: renamed THREADDEBUG envvar to PYTHONTHREADDEBUG.
7321
Georg Brandl3ee81df2008-05-17 18:14:43 +00007322- Patch #602345: Add -B command line option, PYTHONDONTWRITEBYTECODE
7323 envvar and sys.dont_write_bytecode attribute. All these can be set
7324 to forbid Python to attempt to write compiled bytecode files.
Georg Brandl2da0fce2008-01-07 17:09:35 +00007325
Georg Brandl3ee81df2008-05-17 18:14:43 +00007326- Improve some exception messages when Windows fails to load an
7327 extension module. Now we get for example '%1 is not a valid Win32
7328 application' instead of 'error code 193'.
Amaury Forgeot d'Arce0b76952008-01-04 02:04:15 +00007329
Georg Brandl3ee81df2008-05-17 18:14:43 +00007330- Bug #1481296: Fixed long(float('nan')) != 0L.

Georg Brandl3ee81df2008-05-17 18:14:43 +00007332- Issue #1640: Added math.isinf(x), math.isnan(x) and math.copysign(x,
7333 y) functions.
Christian Heimese2ca4242008-01-03 20:23:15 +00007334
Christian Heimes0a8143f2007-12-18 23:22:54 +00007335- Issue #1635: Platform independent creation and representation of NaN
Georg Brandl3ee81df2008-05-17 18:14:43 +00007336 and INF. float("nan"), float("inf") and float("-inf") now work on
7337 every platform with IEEE 754 semantics.
Christian Heimes0a8143f2007-12-18 23:22:54 +00007338
Georg Brandl3ee81df2008-05-17 18:14:43 +00007339- Compiler now generates simpler and faster code for dictionary
7340 literals. The oparg for BUILD_MAP now indicates an estimated
7341 dictionary size. There is a new opcode, STORE_MAP, for adding
7342 entries to the dictionary.

Andrew M. Kuchling395fe442007-12-05 13:27:20 +00007352- Issue #1553: An erroneous __length_hint__ can make list() raise a
Christian Heimes7cc1c6f2007-12-05 12:52:34 +00007353 SystemError.
7354
Nick Coghlanef01d822007-12-03 12:55:17 +00007355- PEP 366: Allow explicit relative imports when executing modules

7360 running, and if the deallocation of its frames somehow calls the
7361 PyGILState_Ensure() / PyGILState_Release() functions.
Amaury Forgeot d'Arcbe49a902007-11-30 20:37:22 +00007362

7367
Georg Brandl3ee81df2008-05-17 18:14:43 +00007368- Issue #1460: The utf-7 incremental decoder did not accept truncated
7369 input. It now correctly saves its state between chunks of data.
Amaury Forgeot d'Arcf57375a2007-11-21 01:38:26 +00007370
Georg Brandl3ee81df2008-05-17 18:14:43 +00007371- Patch #1739468: Directories and zipfiles containing a __main__.py
7372 file can now be directly executed by passing their name to the
7373 interpreter. The directory/zipfile is automatically inserted as the
7374 first entry in sys.path.
Nick Coghlan327a39b2007-11-18 11:56:28 +00007375
Georg Brandl3ee81df2008-05-17 18:14:43 +00007376- Issue #1265: Fix a problem with sys.settrace, if the tracing
7377 function uses a generator expression when at the same time the
7378 executed code is closing a paused generator.
Amaury Forgeot d'Arc0d75f092007-11-13 21:54:28 +00007379
Raymond Hettinger1760c8a2007-11-08 02:52:43 +00007380- sets and frozensets now have an isdisjoint() method.
7381
Raymond Hettinger3f8caa32007-10-24 01:28:33 +00007382- optimize the performance of builtin.sum().
7383
Neal Norwitz44f326e2007-10-05 05:29:17 +00007384- Fix warnings found by the new version of the Coverity checker.
7385
Georg Brandl21e99f42010-03-07 15:23:59 +00007386- The enumerate() built-in function is no longer bounded to sequences
Georg Brandl3ee81df2008-05-17 18:14:43 +00007387 smaller than LONG_MAX. Formerly, it raised an OverflowError. Now,
7388 automatically shifts from ints to longs.
Raymond Hettinger8f669372007-10-03 21:18:11 +00007389
Georg Brandl3ee81df2008-05-17 18:14:43 +00007390- Issue #1686386: Tuple's tp_repr did not take into account the
7391 possibility of having a self-referential tuple, which is possible
7392 from C code. Nor did object's tp_str consider that a type's tp_str
7393 could do something that could lead to an inifinite recursion.
7394 Py_ReprEnter() and Py_EnterRecursiveCall(), respectively, fixed the
7395 issues.
Brett Cannon0b14f242007-09-30 19:45:10 +00007396
Georg Brandl3ee81df2008-05-17 18:14:43 +00007397- Issue #1164: It was possible to trigger deadlock when using the
7398 'print' statement to write to a file since the GIL was not released
7399 as needed. Now PyObject_Print() does the right thing along with
7400 various tp_print implementations of the built-in types and those in
7401 the collections module.
Brett Cannon01531592007-09-17 03:28:34 +00007402
Georg Brandl3ee81df2008-05-17 18:14:43 +00007403- Issue #1147: Exceptions were directly allowing string exceptions in
7404 their throw() method even though string exceptions no longer
7405 allowed.
Brett Cannon4c20bc42007-09-11 21:02:28 +00007406
Georg Brandl3ee81df2008-05-17 18:14:43 +00007407- Issue #1096: Prevent a segfault from getting the repr of a very
7408 deeply nested list by using the recursion counter.
Brett Cannona0c05512007-09-10 21:38:27 +00007409
Brett Cannon1e534b52007-09-07 04:18:30 +00007410- Issue #1202533: Fix infinite recursion calls triggered by calls to
Georg Brandl3ee81df2008-05-17 18:14:43 +00007411 PyObject_Call() never calling back out to Python code to trigger
7412 recursion depth updates/checks. Required the creation of a static
7413 RuntimeError instance in case normalizing an exception put the
7414 recursion check value past its limit. Fixes crashers
7415 infinite_rec_(1|2|4|5).py.
Brett Cannon1e534b52007-09-07 04:18:30 +00007416
Georg Brandl3ee81df2008-05-17 18:14:43 +00007417- Patch #1031213: Decode source line in SyntaxErrors back to its

7421 with %G.
7422
Georg Brandl3ee81df2008-05-17 18:14:43 +00007423- Prevent expandtabs() on string and unicode objects from causing a

Neal Norwitz0ac60192007-05-27 04:08:54 +00007430- Add new attribute names for function objects. All the func_* become
Georg Brandl3ee81df2008-05-17 18:14:43 +00007431 __*__ attributes. (Some already existed, e.g., __doc__ and
7432 __name__.)
Neal Norwitz0ac60192007-05-27 04:08:54 +00007433
Neal Norwitz8b2bfbc2007-05-23 06:35:32 +00007434- Add -3 option to the interpreter to warn about features that are
7435 deprecated and will be changed/removed in Python 3.0.
7436
Georg Brandl2134e752007-05-21 20:34:16 +00007437- Patch #1686487: you can now pass any mapping after '**' in function
7438 calls.
7439
Collin Winter62903052007-05-18 23:11:24 +00007440- except clauses may now be spelled either "except E, target:" or
Georg Brandl3ee81df2008-05-17 18:14:43 +00007441 "except E as target:". This is to provide forwards compatibility
7442 with Python 3.0.
Collin Winter62903052007-05-18 23:11:24 +00007443
Brett Cannon229cee22007-05-05 01:34:02 +00007444- Deprecate BaseException.message as per PEP 352.
7445
Georg Brandl3ee81df2008-05-17 18:14:43 +00007446- Issue #1303614: don't expose object's __dict__ when the dict is
Georg Brandl21e99f42010-03-07 15:23:59 +00007447 inherited from a built-in base.
Armin Rigo9790a272007-05-02 19:23:31 +00007448
Vinay Sajip8549ce32007-05-06 17:53:37 +00007449- When __slots__ are set to a unicode string, make it work the same as
Neal Norwitzcbd9ee62007-04-14 05:25:50 +00007450 setting a plain string, ie don't expand to single letter identifiers.
7451
Raymond Hettinger13936692007-04-11 18:40:58 +00007452- Request #1191699: Slices can now be pickled.
7453
Raymond Hettinger4db5fe92007-04-12 04:10:00 +00007454- Request #1193128: str.translate() now allows a None argument for
7455 translations that only remove characters without re-mapping the
7456 remaining characters.
7457
Georg Brandl5cb76c12007-03-21 09:00:39 +00007458- Patch #1682205: a TypeError while unpacking an iterable is no longer
7459 masked by a generic one with the message "unpack non-sequence".
7460
Neal Norwitzaa754b72007-03-21 06:39:48 +00007461- Remove unused file Python/fmod.c.
7462
Guido van Rossum143b5642007-03-23 04:58:42 +00007463- Bug #1683368: The object.__init__() and object.__new__() methods are
7464 now stricter in rejecting excess arguments. The only time when
7465 either allows excess arguments is when it is not overridden and the
7466 other one is. For backwards compatibility, when both are
7467 overridden, it is a deprecation warning (for now; maybe a Py3k
Guido van Rossum234b1ff2007-03-23 19:39:01 +00007468 warning later). Also, type.__init__() insists on the same signature
7469 as supported by type.__new__().
Guido van Rossum143b5642007-03-23 04:58:42 +00007470
Georg Brandl3ee81df2008-05-17 18:14:43 +00007471- Patch #1675423: PyComplex_AsCComplex() now tries to convert an
7472 object to complex using its __complex__() method before falling back
7473 to the __float__() method. Therefore, the functions in the cmath
7474 module now can operate on objects that define a __complex__()
7475 method.
Georg Brandl2b869942007-03-17 16:08:45 +00007476
Georg Brandl3ee81df2008-05-17 18:14:43 +00007477- Patch #1623563: allow __class__ assignment for classes with
7478 __slots__. The old and the new class are still required to have the
7479 same slot names.
Žiga Seilnacht6f2d09c2007-03-16 11:59:38 +00007480
Georg Brandl3ee81df2008-05-17 18:14:43 +00007481- Patch #1642547: Fix an error/crash when encountering syntax errors

Georg Brandl3ee81df2008-05-17 18:14:43 +00007484- Patch #1462488: Python no longer segfaults when
7485 ``object.__reduce_ex__()`` is called with an object that is faking
7486 its type.
Žiga Seilnacht20f43d32007-03-15 11:44:55 +00007487
Georg Brandl3ee81df2008-05-17 18:14:43 +00007488- Patch #1680015: Don't modify __slots__ tuple if it contains an

7492
Georg Brandl7b9c5552007-03-12 14:30:05 +00007493- Bug #1678647: write a newline after printing an exception in any
7494 case, even when converting the value to a string failed.
7495
Georg Brandl871f1bc2007-03-12 13:17:36 +00007496- The dir() function has been extended to call the __dir__() method on
Georg Brandl3ee81df2008-05-17 18:14:43 +00007497 its argument, if it exists. If not, it will work like before. This
7498 allows customizing the output of dir() in the presence of a
7499 __getattr__().

Collin Winter276887b2007-03-12 16:11:39 +00007501- Patch #922167: Python no longer segfaults when faced with infinitely
7502 self-recursive reload() calls (as reported by bug #742342).
7503
Georg Brandl3ee81df2008-05-17 18:14:43 +00007504- Patch #1675981: remove unreachable code from ``type.__new__()``

Georg Brandl3ee81df2008-05-17 18:14:43 +00007507- Patch #1491866: change the complex() constructor to allow
7508 parthensized forms. This means complex(repr(x)) now works instead of
7509 raising a ValueError.
Collin Wintere38051d2007-03-09 20:33:07 +00007510
Georg Brandlaa2321b2007-03-07 00:40:28 +00007511- Patch #703779: unset __file__ in __main__ after running a file. This
Georg Brandl3ee81df2008-05-17 18:14:43 +00007512 makes the filenames the warning module prints much more sensible
7513 when a PYTHONSTARTUP file is used.
Georg Brandlaa2321b2007-03-07 00:40:28 +00007514
Georg Brandl49aafc92007-03-07 00:34:46 +00007515- Variant of patch #697613: don't exit the interpreter on a SystemExit
7516 exception if the -i command line option or PYTHONINSPECT environment
Georg Brandl3ee81df2008-05-17 18:14:43 +00007517 variable is given, but break into the interactive interpreter just
7518 like on other exceptions or normal program exit.

Georg Brandl0fca97a2007-03-05 22:28:08 +00007526- Patch #1674228: when assigning a slice (old-style), check for the
7527 sq_ass_slice instead of the sq_slice slot.
7528
Georg Brandl3ee81df2008-05-17 18:14:43 +00007529- When printing an unraisable error, don't print exceptions. before
7530 the name. This duplicates the behavior whening normally printing
7531 exceptions.

Facundo Batistab6a5c9d2007-03-29 18:22:35 +00008033- Added a timeout parameter to the constructor of other protocols
8034 (telnetlib, ftplib, smtplib and poplib). This is second part of the
8035 work started with create_connection() and timeout in httplib, and
8036 closes patch #723312.
8037
Vinay Sajip8549ce32007-05-06 17:53:37 +00008038- Patch #1676823: Added create_connection() to socket.py, which may be
8039 called with a timeout, and use it from httplib (whose HTTPConnection
Facundo Batista70f996b2007-05-21 17:32:32 +00008040 and HTTPSConnection now accept an optional timeout).
Facundo Batista07c78be2007-03-23 18:54:07 +00008041
Martin v. Löwis0af33882007-03-23 13:27:15 +00008042- Bug #978833: Revert r50844, as it broke _socketobject.dup.

8062
Georg Brandlf66b6032007-03-14 08:27:52 +00008063- Bug #767111: fix long-standing bug in urllib which caused an
Georg Brandl3ee81df2008-05-17 18:14:43 +00008064 AttributeError instead of an IOError when the server's response
8065 didn't contain a valid HTTP status line.
Georg Brandlf66b6032007-03-14 08:27:52 +00008066
Georg Brandl3ee81df2008-05-17 18:14:43 +00008067- Patch #957650: "%var%" environment variable references are now
8068 properly expanded in ntpath.expandvars(), also "~user" home

Georg Brandl3ee81df2008-05-17 18:14:43 +00008071- Patch #1429539: pdb now correctly initializes the __main__ module
8072 for the debugged script, which means that imports from __main__ work
Georg Brandlb6ae6aa2007-03-13 21:58:44 +00008073 correctly now.
8074
Georg Brandlbad6f192007-03-13 21:32:56 +00008075- The nonobvious commands.getstatus() function is now deprecated.

8081
Georg Brandl3ee81df2008-05-17 18:14:43 +00008082- Patch #1530482: add pydoc.render_doc() which returns the
8083 documentation for a thing instead of paging it to stdout, which

8092 parameter which can be set to False to prevent the default
8093 delete-on-close behavior.
Georg Brandl35ef9c12007-03-13 18:31:49 +00008094
Georg Brandl9e6b4702007-03-13 18:15:41 +00008095- Patch #1581073: add a flag to textwrap that prevents the dropping of
8096 whitespace while wrapping.
8097
Georg Brandl92a6bae2007-03-13 17:43:32 +00008098- Patch #1603688: ConfigParser.SafeConfigParser now checks values that
Georg Brandl3ee81df2008-05-17 18:14:43 +00008099 are set for invalid interpolation sequences that would lead to
8100 errors on reading back those values.
Georg Brandl92a6bae2007-03-13 17:43:32 +00008101

Georg Brandl3ee81df2008-05-17 18:14:43 +00008116 field names in its exception message if you try to write a record
8117 with a dictionary containing fields not in the CSV field names list.

8141

8143 returned string up to the first NUL character.
8144

8154
Georg Brandl3ee81df2008-05-17 18:14:43 +00008155- unittest now verifies more of its assumptions. In particular,
8156 TestCase and TestSuite subclasses (not instances) are no longer
8157 accepted in TestSuite.addTest(). This should cause no
8158 incompatibility since it never made sense with ordinary subclasses
8159 -- the failure just occurred later, with a more cumbersome
8160 exception.
Georg Brandl9caadf82007-03-08 18:37:31 +00008161

8170
Georg Brandl3ee81df2008-05-17 18:14:43 +00008171- Patch #1673619: setup.py identifies extension modules it doesn't

8531 complex, tuple, list, dict, set, and frozenset. Formerly, it would

Gregory P. Smithec10a4a2007-11-05 02:32:26 +00008548- pybsddb.sf.net Bug #477182: Load the database flags at database open
Georg Brandl3ee81df2008-05-17 18:14:43 +00008549 time so that opening a database previously created with the DB_DUP
8550 or DB_DUPSORT flag set will keep the proper behavior on subsequent
8551 opens. Specifically: dictionary assignment to a DB object will
8552 replace all values for a given key when the database allows
8553 duplicate values. DB users should use DB.put(k, v) when they want
8554 to store duplicates; not DB[k] = v.

8561 characters with ASCII value less than 32. Also, it correctly quotes
8562 dots only if they occur on a single line, as opposed to the previous
8563 behavior of quoting dots if they are the second character of any
8564 line.
Georg Brandl4aef7272007-03-13 22:49:43 +00008565

Georg Brandl3ee81df2008-05-17 18:14:43 +00008942- Added case insensitive comparison methods ``PyOS_stricmp(char*,
8943 char*)`` and ``PyOS_strnicmp(char*, char*, Py_ssize_t)``.
