115
R. David Murray27ef9372010-04-12 14:26:06 +0000116- Issue #7472: Fixed typo in email.encoders module; messages using ISO-2022

154-----------------
155
Philip Jenveyaebbaeb2010-04-06 23:24:45 +0000156- Issue #7301: Add environment variable $PYTHONWARNINGS.
157

159 changed.
160
Mark Dickinson82791672010-04-06 16:47:55 +0000161- Issue #8259: 1L << (2**31) no longer produces an 'outrageous shift error'
162 on 64-bit machines. The shift count for either left or right shift is
163 permitted to be up to sys.maxsize.
164
Benjamin Peterson4ceeeb02010-04-03 22:48:51 +0000165- Ensure that tokenization of identifiers is not affected by locale.

172 is called with a non-empty format string. This is an effort to
173 future-proof user code. If a derived class does not currently
174 implement __format__ but later adds its own __format__, it would
175 most likely break user code that had supplied a format string. This
176 will be changed to a DeprecationWaring in Python 3.3 and it will be
177 an error in Python 3.4.
178
Antoine Pitroua57df2c2010-03-31 21:32:15 +0000179- Issue #8268: Old-style classes (not just instances) now support weak

Georg Brandlba83f822010-03-14 09:50:54 +0000193 (SIGINT). If an error occurs while importing the site module, the error is
194 printed and Python exits. Initialize the GIL before importing the site
Victor Stinner66644262010-03-10 22:30:19 +0000195 module.
196
Collin Winter001a3952010-03-18 21:54:01 +0000197- Code objects now support weak references.

Antoine Pitrouf9de5342010-04-05 21:35:07 +0000204- Issue #8321: Give access to OpenSSL version numbers from the `ssl` module,
205 using the new attributes `ssl.OPENSSL_VERSION`, `ssl.OPENSSL_VERSION_INFO`
206 and `ssl.OPENSSL_VERSION_NUMBER`.
207
Benjamin Peterson76a23c12010-04-04 23:23:22 +0000208- Issue #8310: Allow dis to examine new style classes.
209
Mark Dickinson8a950712010-04-03 15:47:46 +0000210- Issue #8257: The Decimal construct now accepts a float instance
211 directly, converting that float to a Decimal of equal value:

217
Raymond Hettingera551f312010-04-04 18:34:45 +0000218- the functools module now has a total_ordering() class decorator
Georg Brandl4fabac52010-04-14 08:53:38 +0000219 to simplify the specification of rich comparisons.
Raymond Hettingera551f312010-04-04 18:34:45 +0000220
Raymond Hettingerbb006cf2010-04-04 21:45:01 +0000221- The functools module also adds cmp_to_key() as a tool to transition
Raymond Hettingera551f312010-04-04 18:34:45 +0000222 old-style comparison functions to new-style key-functions.
223
Mark Dickinson7c63eee2010-04-02 22:27:36 +0000224- Issue #8294: The Fraction constructor now accepts Decimal and float
225 instances directly.
226
Mark Dickinsone096e822010-04-02 10:17:07 +0000227- Issue #7279: Comparisons involving a Decimal signaling NaN now
228 signal InvalidOperation instead of returning False. (Comparisons
Mark Dickinsonf3eeca12010-04-02 10:35:12 +0000229 involving a quiet NaN are unchanged.) Also, Decimal quiet NaNs
230 are now hashable; Decimal signaling NaNs remain unhashable.
Mark Dickinsone096e822010-04-02 10:17:07 +0000231
Mark Dickinson99d80962010-04-02 08:53:22 +0000232- Issue #2531: Comparison operations between floats and Decimal

Barry Warsawf7f2d6f2010-03-31 21:07:16 +0000237- Issue #8233: When run as a script, py_compile.py optionally takes a single
238 argument `-` which tells it to read files to compile from stdin. Each line
239 is read on demand and the named file is compiled immediately. (Original
240 patch by Piotr Ożarowski).
241
242- Issue #3135: Add inspect.getcallargs, which binds arguments to a function
243 like a normal call.
Benjamin Peterson7e213252010-03-30 17:58:13 +0000244
Florent Xicluna58b65662010-03-30 16:29:03 +0000245- Backwards incompatible change: Unicode codepoints line tabulation (0x0B) and
246 form feed (0x0C) are now considered linebreaks, as specified in Unicode
247 Standard Annex #14. See issue #7643.
Florent Xicluna22b24382010-03-30 08:24:06 +0000248 http://www.unicode.org/reports/tr14/
249
Mark Dickinson9588d992010-03-27 11:14:37 +0000250- Comparisons using one of <, <=, >, >= between a complex instance and
251 a Fractions instance now raise TypeError instead of returning
252 True/False. This makes Fraction <=> complex comparisons consistent with
253 int <=> complex, float <=> complex, and complex <=> complex comparisons.
254
Michael Foorde6410c52010-03-29 20:04:23 +0000255- Addition of ``WeakSet`` to the ``weakref`` module.

358 integer format code (one of 'bBhHiIlLqQ'), struct.pack attempts to use the
359 argument's __int__ method to convert to an integer before packing. It also
360 produces a DeprecationWarning in this case. (In Python 2.6, the behaviour
361 was inconsistent: __int__ was used for some integer codes but not for others,
362 and the set of integer codes for which it was used differed between native
363 packing and standard packing.)

604 and add the additional members returned in an OSVERSIONINFOEX structure. The
605 new members are service_pack_major, service_pack_minor, suite_mask, and

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

Antoine Pitrouf3fa0742010-01-31 22:26:04 +0000660- Issue #6939: Fix file I/O objects in the `io` module to keep the original
Georg Brandlba83f822010-03-14 09:50:54 +0000661 file position when calling `truncate()`. It would previously change the file
662 position to the given argument, which goes against the tradition of
Antoine Pitrouf3fa0742010-01-31 22:26:04 +0000663 ftruncate() and other truncation APIs. Patch by Pascal Chambon.
664
Benjamin Petersone06f7112010-01-28 02:15:02 +0000665- UserDict is now a new-style class.
666
Georg Brandlba83f822010-03-14 09:50:54 +0000667- Issue #7610: Reworked implementation of the internal ``zipfile.ZipExtFile``
668 class used to represent files stored inside an archive. The new
669 implementation is significantly faster and can be wrapped in a
670 ``io.BufferedReader`` object for more speedups. It also solves an issue
671 where interleaved calls to ``read()`` and ``readline()`` give wrong results.
672 Patch by Nir Aides.

680 when the release file is empty.
Benjamin Petersona43f34c2010-01-25 03:31:13 +0000681
Georg Brandlba83f822010-03-14 09:50:54 +0000682- Issue #7748: Since unicode values are supported for some metadata options in
683 Distutils, the DistributionMetadata get_* methods will now return an utf-8
684 encoded string for them. This ensures that the upload and register commands
685 send the correct values to PyPI without any error.

Georg Brandlba83f822010-03-14 09:50:54 +0000687- Issue #1670765: Prevent ``email.generator.Generator`` from re-wrapping
R. David Murrayed44dfa2010-01-16 05:15:17 +0000688 headers in multipart/signed MIME parts, which fixes one of the sources of

759Core and Builtins
760-----------------
761
Georg Brandlba83f822010-03-14 09:50:54 +0000762- The ``__complex__()`` method is now looked up on the class of instances to
763 make it consistent with other special methods.
Benjamin Petersonecdae192010-01-04 00:43:01 +0000764
Antoine Pitrou5b7139a2010-01-02 21:12:58 +0000765- Issue #7462: Implement the stringlib fast search algorithm for the `rfind`,
766 `rindex`, `rsplit` and `rpartition` methods. Patch by Florent Xicluna.
767
Mark Dickinson1b34d252010-01-01 17:27:30 +0000768- Issue #5080: A number of functions and methods previously produced a
Georg Brandlba83f822010-03-14 09:50:54 +0000769 DeprecationWarning when passed a float argument where an integer was expected.
770 These functions and methods now raise TypeError instead. The majority of the
771 effects of this change are in the extension modules, but some core functions
772 and methods are affected: notably the 'chr', 'range' and 'xrange' builtins,
773 and many unicode/str methods.

Georg Brandlba83f822010-03-14 09:50:54 +0000786- Issue #1811: Improve accuracy and cross-platform consistency for true division
787 of integers: the result of a/b is now correctly rounded for ints a and b (at
788 least on IEEE 754 platforms), and in particular does not depend on the
789 internal representation of a long.

797
Georg Brandlba83f822010-03-14 09:50:54 +0000798 These executables now work properly with the arch(1) command: ``arch -ppc
799 python`` will start a universal binary version of python in PPC mode (unlike

940 to 'g' for large values.
Amaury Forgeot d'Arcd7288712009-12-01 21:51:04 +0000941
Georg Brandlba83f822010-03-14 09:50:54 +0000942- Remove switch from "%f" formatting to "%g" formatting for floats larger than
943 1e50 in absolute value.
Mark Dickinson9dd5e162009-11-23 20:54:09 +0000944

954 10.6.
Ronald Oussoren315cd0c2009-11-19 16:25:21 +0000955
Georg Brandlba83f822010-03-14 09:50:54 +0000956- Issue #7117: ``repr(x)`` for a float x returns a result based on the shortest
957 decimal string that's guaranteed to round back to x under correct rounding
958 (with round-half-to-even rounding mode). Previously it gave a string based on
959 rounding x to 17 decimal digits. repr(x) for a complex number behaves
960 similarly. On platforms where the correctly-rounded strtod and dtoa code is
961 not supported (see below), repr is unchanged.
Mark Dickinsonb678de82009-11-19 18:41:49 +0000962
Georg Brandlba83f822010-03-14 09:50:54 +0000963- Issue #7117: On almost all platforms: float-to-string and string-to-float
964 conversions within Python are now correctly rounded. Places these conversions
965 occur include: str for floats and complex numbers; the float and complex
966 constructors; old-style and new-style numeric formatting; serialization and
967 deserialization of floats and complex numbers using marshal, pickle and json;
968 parsing of float and imaginary literals in Python code; Decimal-to-float
969 conversion.
Mark Dickinsonb678de82009-11-19 18:41:49 +0000970
Georg Brandlba83f822010-03-14 09:50:54 +0000971 The conversions use a Python-adapted version of David Gay's well-known dtoa.c,
972 providing correctly-rounded strtod and dtoa C functions. This code is
973 supported on Windows, and on Unix-like platforms using gcc, icc or suncc as
974 the C compiler. There may be a small number of platforms on which correct
975 operation of this code cannot be guaranteed, so the code is not used: notably,
976 this applies to platforms where the C double format is not IEEE 754 binary64,
977 and to platforms on x86 hardware where the x87 FPU is set to 64-bit precision
978 and Python's configure script is unable to determine how to change the FPU
979 precision. On these platforms conversions use the platform strtod and dtoa,
980 as before.
Mark Dickinsonb678de82009-11-19 18:41:49 +0000981
Georg Brandlba83f822010-03-14 09:50:54 +0000982- Issue #7117: Backport round implementation from Python 3.x. ``round()`` now
983 uses the correctly-rounded string <-> float conversions described above (when
984 available), and so produces correctly rounded results that will display nicely
985 under the float repr. There are two related small changes: (1) round now
986 accepts any class with an ``__index__()`` method for its second argument (but
987 no longer accepts floats for the second argument), and (2) an excessively
988 large second integer argument (e.g., ``round(1.234, 10**100)``) no longer
989 raises an exception.

Georg Brandlba83f822010-03-14 09:50:54 +0000993- Fix several issues with ``compile()``. The input can now contain Windows and

Georg Brandlba83f822010-03-14 09:50:54 +00001136- Issue #5920: For ``float.__format__()``, change the behavior with the empty
1137 presentation type (that is, not one of 'e', 'f', 'g', or 'n') to be like 'g'
1138 but with at least one decimal point and with a default precision
1139 of 12. Previously, the behavior the same but with a default precision of 6.
1140 This more closely matches ``str()``, and reduces surprises when adding
1141 alignment flags to the empty presentation type. This also affects the new
1142 complex.__format__ in the same way.

Georg Brandlba83f822010-03-14 09:50:54 +00001282- Issue #1180193: When importing a module from a .pyc (or .pyo) file with an
1283 existing .py counterpart, override the co_filename attributes of all code

1339
Georg Brandlba83f822010-03-14 09:50:54 +00001340- Issue #4233: Changed semantic of ``_fileio.FileIO``'s ``close()`` method on
1341 file objects with closefd=False. The file descriptor is still kept open but
1342 the file object behaves like a closed file. The ``FileIO`` object also got a

Georg Brandlba83f822010-03-14 09:50:54 +00001366- On windows, ``os.chdir()`` given unicode was not working if

1368 this code path is really executed because I cannot move to such directory on
1369 win2k)

1372 element is temporarily replaced with an equivalent frozenset. But the
1373 eventual KeyError would always report the empty ``frozenset()`` as the missing

Walter Dörwalded960ac2009-05-03 22:36:33 +00001394- Issue #5108: Handle %s like %S and %R in PyUnicode_FromFormatV(): Call
1395 PyUnicode_DecodeUTF8() once, remember the result and output it in a second
1396 step. This avoids problems with counting UTF-8 bytes that ignores the effect
1397 of using the replace error handler in PyUnicode_DecodeUTF8().
1398
Walter Dörwald726ba8e2009-05-06 14:32:35 +00001399- Issue #3739: The unicode-internal encoder now reports the number of characters

Georg Brandlba83f822010-03-14 09:50:54 +00001402- Issue #2422: When compiled with the ``--with-valgrind`` option, the pymalloc

1404 gives improved memory leak detection when running under Valgrind, while taking
1405 advantage of pymalloc at other times.

Guilherme Polo7f146ab2009-06-21 17:22:50 +00002647- Issue #5450: Moved tests involving loading tk from Lib/test/test_tcl to
2648 Lib/lib-tk/test/test_tkinter/test_loadtk. With this, these tests demonstrate
Georg Brandlba83f822010-03-14 09:50:54 +00002649 the same behaviour as test_ttkguionly (and now also test_tk) which is to skip
2650 the tests if DISPLAY is defined but can't be used.

2656 import both normal and optimised versions of modules. test_heapq and

2668 should cause a test to be skipped are now done using import_module from test
2669 support, which does the conversion.

2771
Amaury Forgeot d'Arc05e34492008-09-10 22:04:45 +00002772- Issue #3743: In a few places, PY_FORMAT_SIZE_T was incorrectly used with
2773 PyString_FromFormat or PyErr_Format to display size_t values. The macro
2774 PY_FORMAT_SIZE_T is designed to select the correct format for the OS
2775 ``printf`` function, whereas PyString_FromFormat has an independent
2776 implementation and uses "%zd" on all platforms for size_t values.
2777 This makes a difference on win64, where ``printf`` needs "%Id" to display
2778 64bit values.

Benjamin Peterson97179b02008-09-09 20:55:01 +00002780- Issue #3634: _weakref.ref(Exception).__init__() gave invalid return value on

2784 object; previously an int would be returned for small values. the __long__

Vinay Sajip35e3b032008-09-01 14:33:59 +00002794 PyArg_ParseTuple and friends, which occurred when the argument for "s*"
Antoine Pitroud4ae97b2008-08-29 18:39:48 +00002795 was correctly parsed but parsing of subsequent arguments failed.
2796
Vinay Sajip35e3b032008-09-01 14:33:59 +00002797- Issue #2534: speed up isinstance() and issubclass() by 50-70%, so as to
Antoine Pitrou0668c622008-08-26 22:42:08 +00002798 match Python 2.5 speed despite the __instancecheck__ / __subclasscheck__
2799 mechanism. In the process, fix a bug where isinstance() and issubclass(),
2800 when given a tuple of classes as second argument, were looking up
2801 __instancecheck__ / __subclasscheck__ on the tuple rather than on each
2802 type object.
2803
Neal Norwitz18aa3882008-08-24 05:04:52 +00002804- Fix crashes on memory allocation failure found with failmalloc.

Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00002941What's New in Python 2.6 beta 3?
2942================================
2943
Barry Warsaw07a4a382008-08-21 01:15:08 +00002944*Release date: 20-Aug-2008*
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00002945
2946Core and Builtins
2947-----------------
2948
Guido van Rossumf8402962008-08-20 15:01:50 +00002949- Issue #1878: Remove Py_TPFLAGS_HAVE_VERSION_TAG from
2950 Py_TPFLAGS_DEFAULT when not building the core. This means 3rd party
2951 extensions do not automatically benefit from the class attribute
2952 cache; they will have to explicitly add Py_TPFLAGS_HAVE_VERSION_TAG
2953 to their tp_flags field if they care. This is a backwards
2954 compatibility feature; in 3.0, all types will use the cache by
2955 default.
2956
Benjamin Petersonf647dc12008-08-20 01:27:30 +00002957- Keyword arguments can now follow starred arguments. (``f(a, *args,
2958 keyword=23)`` is now valid syntax.)
2959
Thomas Heller0ad5ae02008-08-19 19:25:04 +00002960- ctypes function pointers that are COM methods have a boolean True
2961 value again.
2962
Martin v. Löwisf91d46a2008-08-12 14:49:50 +00002963- Issue #3139: Make buffer-interface thread-safe wrt. PyArg_ParseTuple,
2964 by denying s# to parse objects that have a releasebuffer procedure,
2965 and introducing s*.
2966
Georg Brandl1e13ea92008-08-11 09:07:59 +00002967- Issue #3537: Fix an assertion failure when an empty but presized dict
2968 object was stored in the freelist.
2969
Mark Dickinsonb6467572008-08-04 21:30:09 +00002970- Issue #1481296: Make long(float('nan')) and int(float('nan')) raise
2971 ValueError consistently across platforms.
2972
Amaury Forgeot d'Arc39fd6722008-07-31 21:28:03 +00002973- Issue #3479: On platforms where sizeof(int) is smaller than sizeof(long)
2974 (64bit Unix, for example), unichr() would truncate its argument and return
2975 u'\x00' for unichr(2**32). Now it properly raises an OverflowError.
2976
Neal Norwitze7d8be82008-07-31 17:17:14 +00002977- Apply security patches from Apple.
2978
Amaury Forgeot d'Arc246daed2008-07-31 00:42:16 +00002979- Issue #2542: Now that issubclass() may call arbitrary code, ensure that
2980 PyErr_ExceptionMatches returns 0 when an exception occurs there.
2981
Antoine Pitrou92f82162008-07-25 22:22:08 +00002982- Issue #1819: function calls with several named parameters are now on
2983 average 35% faster (as measured by pybench).
2984
Amaury Forgeot d'Arce4921fe2008-07-21 22:00:38 +00002985- Issue #2378: An unexpected UnboundLocalError or NameError could appear when
2986 the python debugger steps into a class statement: the free variables (local
2987 variables defined in an outer scope) would be deleted from the outer scope.
2988
Gregory P. Smith0470bab2008-07-22 04:46:32 +00002989- Issue #2620: Overflow checking when allocating or reallocating memory
2990 was not always being done properly in some python types and extension
2991 modules. PyMem_MALLOC, PyMem_REALLOC, PyMem_NEW and PyMem_RESIZE have
2992 all been updated to perform better checks and places in the code that
2993 would previously leak memory on the error path when such an allocation
2994 failed have been fixed.

2997-------
2998
Hirokazu Yamamoto838c79f2008-08-20 13:14:07 +00002999- Issue #3612: Added some missing basic types in ctypes.wintypes.
3000
Benjamin Petersone977ad42008-08-20 01:42:01 +00003001- The methods ``is_in_tuple()``, ``is_vararg()``, and ``is_keywordarg()`` of
3002 symtable.Symbol have been deprecated for removal in 3.0 and the next release.
3003
Amaury Forgeot d'Arc351ffb82008-08-18 19:23:47 +00003004- Issue #2234: distutils failed for some versions of the cygwin compiler. The
3005 version reported by these tools does not necessarily follow the python
3006 version numbering scheme, so the module is less strict when parsing it.
3007
Nick Coghlanf70385a2008-08-18 12:42:46 +00003008- Issue #2235: Added Py3k warnings for types which will become unhashable
3009 under the stricter __hash__ inheritance rules in 3.0. Several types
3010 which did not meet the rules for hash invariants and were already
3011 unhashable in 3.0 have now been explicitly flagged as unhashable in
3012 2.6 as well (collections.Mapping, collections.Set, unittest.TestSuite,
3013 xml.dom.minidom.NamedNodeMap, numbers.Number, UserList.UserList)
3014
Brett Cannon88f801d2008-08-18 00:46:22 +00003015- Update __all__ for cookielib, csv, os, urllib2, and weakref to include things
3016 imported into the module but exposed as part of the module's API.
3017
Brett Cannon7b96f072008-08-18 00:41:11 +00003018- Remove an unneeded import of abc.ABCMeta from 'inspect'.
3019
Brett Cannon46225e72008-08-18 00:36:52 +00003020- Remove unneeded imports of 'sys' and 'warnings' from 'io'.
3021
Brett Cannon25c9d6a2008-08-17 22:10:11 +00003022- Remove unneeded imports of 'warnings' from shelve, filecmp, and dummy_thread.
3023
Hirokazu Yamamoto41a81eb2008-08-17 13:10:46 +00003024- Issue #3575: Incremental decoder's decode function now takes bytearray
3025 by using 's*' instead of 't#'.
3026
Mark Dickinson3e4caeb2009-02-21 20:27:01 +00003027- Issue #2222: Fixed reference leak when occurred os.rename()
Hirokazu Yamamoto7f30a682008-08-17 09:46:56 +00003028 fails unicode conversion on 2nd parameter. (windows only)
3029
Facundo Batista94f243a2008-08-17 03:38:39 +00003030- Issue 2464. urllib2 now supports a malformation in the URL received
3031 in a redirect.
3032
Brett Cannonabe423e2008-08-16 21:47:07 +00003033- Silence the DeprecationWarning raised when importing mimetools in
Brett Cannon721b1452008-08-16 22:00:27 +00003034 BaseHTTPServer, cgi (and rfc822), httplib.
Brett Cannonabe423e2008-08-16 21:47:07 +00003035
Facundo Batistaeb90b782008-08-16 14:44:07 +00003036- Issue #2776: fixed small issue when handling an URL with double slash
3037 after a 302 response in the case of not going through a proxy.
3038
Antoine Pitroub90a8be2008-08-15 21:03:21 +00003039- Issue #2676: in the email package, content-type parsing was hanging on
3040 pathological input because of quadratic or exponential behaviour of a
3041 regular expression.
3042
Antoine Pitrou11ec65d2008-08-14 21:04:30 +00003043- Issue #3476: binary buffered reading through the new "io" library is now
3044 thread-safe.
3045
Brett Cannonbf3157b2008-08-14 05:00:03 +00003046- Silence the DeprecationWarning of rfc822 when it is imported by mimetools
3047 since mimetools itself is deprecated. Because modules are cached, all
3048 subsequent imports of rfc822 will not raise a visible DeprecationWarning.
3049
Antoine Pitrou9fcd4b32008-08-11 17:21:36 +00003050- Issue #3134: shutil referenced undefined WindowsError symbol.
3051
Robert Schuppenies14646332008-08-10 11:01:53 +00003052- Issue #1342811: Fix leak in Tkinter.Menu.delete. Commands associated to
3053 menu entries were not deleted.
3054
Brett Cannon83e81842008-08-09 23:30:55 +00003055- Copied the implementation of reduce() to _functools.reduce() to have a
3056 version that did not raise a DeprecationWarning under -3.
3057
Antoine Pitrou76b8bee2008-08-09 17:27:23 +00003058- Issue #3205: When iterating over a BZ2File fails allocating memory, raise
3059 a MemoryError rather than silently stop the iteration.
3060
Guido van Rossum59ce9012008-08-09 14:55:34 +00003061- Issue #3487: sre "bytecode" validator. Passing invalid "re-bytecode"
3062 to _sre.compile() will now be rejected. This should not affect anybody
3063 since the re.compile() function never generates invalid re-bytecode.
3064
Skip Montanaroa032bf42008-08-08 22:52:51 +00003065- Issue #3436: Make csv.DictReader's fieldnames attribute a property so that
3066 upon first access it can be automatically initialized from the csv file if
3067 it wasn't initialized during instantiation.
3068
Brett Cannon3aa2a492008-08-06 22:28:09 +00003069- Issue #2338: Create imp.reload() to help with transitioning to Python 3.0 as
3070 the reload() built-in has been removed.
3071
Brett Cannon7e30b672008-08-04 21:52:25 +00003072- Changed code in the following modules/packages to remove warnings raised
Brett Cannonc1b76e42008-08-09 23:06:16 +00003073 while running under the ``-3`` flag: aifc, asynchat, asyncore, bdb, bsddb,

Lars Gustäbel727bd0b2008-08-02 11:26:39 +00003080- Issue #3039: Fix tarfile.TarFileCompat.writestr() which always
3081 raised an AttributeError.
3082
Benjamin Peterson01a24322008-07-28 23:35:27 +00003083- Issue #2523: Fix quadratic behaviour when read()ing a binary file without
Antoine Pitroude781a42008-08-09 12:43:23 +00003084 asking for a specific length. This problem only affected files opened
3085 using the new "io" module, not the built-in open() function.
Benjamin Peterson01a24322008-07-28 23:35:27 +00003086
Mark Dickinsonfe84cce2008-07-27 06:39:07 +00003087- Issue #3449: Update decimal module to use most recent specification
3088 (v. 1.68) and tests (v. 2.58) from IBM.
3089
Skip Montanarof9ac43f2008-07-27 00:50:41 +00003090- Issue 3437: Bug fix in robotparser parsing of Allow: lines.

3098
3099- Issue #3303: Fix a crash in locale.strcoll() when calling it with
3100 invalid arguments.
3101
3102- Issue #3302: Fix several crashes when calling locale's gettext functions
3103 with None arguments.
3104
3105- Issue #3389: Allow resolving dotted names for handlers in logging
3106 configuration files.
3107
3108- Deprecate the sunaudio module for removal in Python 3.0.
3109
Antoine Pitrou5fdfa3e2008-07-25 19:42:26 +00003110- Issue #3394: zipfile.writestr sets external attributes when passed a
3111 file name rather than a ZipInfo instance, so files are extracted with
3112 mode 0600 rather than 000 under Unix.
3113
Gregory P. Smitha36f8fe2008-08-04 00:13:29 +00003114- Issue #1857: subprocess.Popen.poll gained an additional _deadstate keyword
3115 argument in python 2.5, this broke code that subclassed Popen to include its
3116 own poll method. Fixed my moving _deadstate to an _internal_poll method.

Nick Coghlan6e8fef02008-08-18 13:14:22 +00003126- Issue #2235: the C API function PyObject_HashNotImplemented and its
3127 interaction with the tp_hash slot (added in 2.6b2) are now documented
3128
Nick Coghlan2a0c2b12008-08-04 12:47:17 +00003129- Issue #643841: The language reference now provides more detailed
3130 coverage of the lookup process for special methods. The disclaimers
3131 regarding lack of coverage of new-style classes have also been
3132 removed, since the coverage is now fairly reasonable.

3142
Georg Brandl3e483f62008-07-16 22:57:41 +00003143- Issue #3156: Fix inconsistent behavior of the bytearray type: all
3144 its methods now allow for items objects that can be converted to
3145 an integer using operator.index().
3146
Mark Dickinson64b7e502008-07-16 09:40:03 +00003147- Issue #3360: Fix incorrect parsing of '020000000000.0', which
3148 produced a ValueError instead of giving the correct float.
3149
Eric Smitha5fa5a22008-07-16 00:11:49 +00003150- Issue #3083: Add alternate (#) formatting for bin, oct, hex output
3151 for str.format(). This adds the prefix 0b, 0o, or 0x, respectively.
3152
Mark Dickinson7103aa42008-07-15 19:08:33 +00003153- Issue #3008: the float type has a new instance method 'float.hex'
3154 and a new class method 'float.fromhex' to convert floating-point
3155 numbers to and from hexadecimal strings, respectively.
3156
Nick Coghlan6d6bd442008-07-15 15:40:22 +00003157- Issue #2235: __hash__ is once again inherited by default. To allow
3158 collections.Hashable to remain meaningful in the presence of the
3159 default hash implementation (object.__hash__), it is now possible
3160 to explicit block inheritance of hash by setting __hash__=None at
3161 the Python level, or tp_hash=PyObject_HashNotImplemented at the C
3162 level.
3163
Nick Coghlanb028f502008-07-13 14:52:36 +00003164- Issue #3221: Issue a RuntimeWarning instead of raising SystemError if
3165 the parent module cannot be found while performing an absolute import.
3166 This means that an incorrectly defined __package__ attribute will
3167 now only prevent relative imports in that module rather than causing
3168 all imports from that module to fail.
3169
Nick Coghlan14ff9942008-07-08 14:21:42 +00003170- Issue #2517: Allow unicode messages in Exceptions again by correctly
3171 bypassing the instance dictionary when looking up __unicode__ on
3172 new-style classes.

3180 another thread's dictionary.
3181
Mark Dickinson1ec2fcd2008-06-20 14:53:43 +00003182- Issue #3004: Minor change to slice.indices(): the start and stop
3183 arguments are now treated identically, making the behaviour easier
3184 to describe and understand. For example, slice(None, -10,
3185 1).indices(9) now returns (0, 0, 1) instead of (0, -1, 1), and
3186 slice(None, 10, -1).indices(10) returns (9, 9, -1) instead of (9,
3187 10, -1).

Georg Brandl278fc502008-07-19 12:46:12 +00003189- Issue #3219: Calling a function with repeated keyword arguments,

Georg Brandl5cc774e2008-06-11 20:28:06 +00003641 PPC64 and x86_64 support in one binary).
Ronald Oussoren5640ce22008-06-05 12:58:24 +00003642
3643 This is controlled by the configure argument ``--with-universal-archs``:
3644
3645 - ``--with-universal-archs=all``: install 4-way universal
3646
3647 - ``--with-universal-archs=32-bit``: install 2-way universal, 32-bit (the default)
3648
3649 - ``--with-universal-archs=64-bit``: install 2-way universal, 64-bit
3650
3651 This option should be used in combination with ``--enable-universalsdk=``.

Georg Brandl3ee81df2008-05-17 18:14:43 +00003703- Issue #1631171: Re-implement the 'warnings' module in C (the
3704 original Python code has been kept as backup). This will allow for
3705 using the 'warning's machinery in such places as the parser where
3706 use of pure Python code is not possible. Both the ``showarning()``
3707 and ``formatwarning()`` gain an optional 'line' argument which is
3708 not called by default for backwards-compatibility reasons. Setting
3709 ``warnings.showwarning()`` to an implementation that lacks support
3710 for the ``line`` argument will raise a DeprecationWarning.

Georg Brandl3ee81df2008-05-17 18:14:43 +00003752- Issue #2513: distutils on Windows is now capable of cross-compiling
Mark Hammond495cf992008-04-07 01:53:39 +00003753 extension modules between 32 and 64 bit platforms. See the distutls

Georg Brandl3ee81df2008-05-17 18:14:43 +00003765- Issue #2385: distutils.core.run_script() makes __file__ available,
3766 so the controlled environment will more closely mirror the typical
3767 script environment. This supports setup.py scripts that refer to
3768 data files.

Georg Brandl3ee81df2008-05-17 18:14:43 +00003773- Issue #2550: The approach used by client/server code for obtaining
3774 ports to listen on in network-oriented tests has been refined in an
3775 effort to facilitate running multiple instances of the entire
3776 regression test suite in parallel without issue.
3777 test_support.bind_port() has been fixed such that it will always
3778 return a unique port -- which wasn't always the case with the
3779 previous implementation, especially if socket options had been set
3780 that affected address reuse (i.e. SO_REUSEADDR, SO_REUSEPORT). The
3781 new implementation of bind_port() will actually raise an exception
3782 if it is passed an AF_INET/SOCK_STREAM socket with either the
3783 SO_REUSEADDR or SO_REUSEPORT socket option set. Furthermore, if
3784 available, bind_port() will set the SO_EXCLUSIVEADDRUSE option on
3785 the socket it's been passed. This currently only applies to
3786 Windows. This option prevents any other sockets from binding to the
3787 host/port we've bound to, thus removing the possibility of the
3788 'non-deterministic' behaviour, as Microsoft puts it, that occurs
3789 when a second SOCK_STREAM socket binds and accepts to a host/port
3790 that's already been bound by another socket. The optional preferred
3791 port parameter to bind_port() has been removed. Under no
3792 circumstances should tests be hard coding ports!
3793
3794 test_support.find_unused_port() has also been introduced, which will
3795 pass a temporary socket object to bind_port() in order to obtain an
3796 unused port. The temporary socket object is then closed and
3797 deleted, and the port is returned. This method should only be used
3798 for obtaining an unused port in order to pass to an external program
3799 (i.e. the -accept [port] argument to openssl's s_server mode) or as
3800 a parameter to a server-oriented class that doesn't give you direct
3801 access to the underlying socket used.
3802
3803 Finally, test_support.HOST has been introduced, which should be used
3804 for the host argument of any relevant socket calls (i.e. bind and
3805 connect).
Trent Nelsone41b0062008-04-08 23:47:30 +00003806
3807 The following tests were updated to following the new conventions:
Georg Brandl3ee81df2008-05-17 18:14:43 +00003808 test_socket, test_smtplib, test_asyncore, test_ssl, test_httplib,
Trent Nelsone41b0062008-04-08 23:47:30 +00003809 test_poplib, test_ftplib, test_telnetlib, test_socketserver,
3810 test_asynchat and test_socket_ssl.
3811
Georg Brandl3ee81df2008-05-17 18:14:43 +00003812 It is now possible for multiple instances of the regression test
3813 suite to run in parallel without issue.

Fred Drakea8ee94b2008-03-01 02:45:07 +00004082- Issue #2051: pyc and pyo files are no longer created with permission
Barry Warsaw52973612008-03-01 02:23:38 +00004083 644. The mode is now inherited from the py file.

4086
4087- Patch #1759: Backport of PEP 3129 class decorators.
Christian Heimes5224d282008-02-23 15:01:05 +00004088
Vinay Sajipb7edfc42008-04-02 21:10:23 +00004089- Issue #1881: An internal parser limit has been increased. Also see
Facundo Batistafc2d0102008-02-23 12:01:13 +00004090 issue 215555 for a discussion.
4091
Eric Smitha73fbe72008-02-23 03:09:44 +00004092- Added the future_builtins module, which contains hex() and oct().
4093 These are the PEP 3127 version of these functions, designed to be
4094 compatible with the hex() and oct() builtins from Python 3.0. They
4095 differ slightly in their output formats from the existing, unchanged
4096 Python 2.6 builtins. The expected usage of the future_builtins
4097 module is:
4098 from future_builtins import hex, oct
4099
Eric Smith7ef40bf2008-02-20 23:34:22 +00004100- Issue #1600: Modifed PyOS_ascii_formatd to use at most 2 digit
4101 exponents for exponents with absolute value < 100. Follows C99
4102 standard. This is a change on Windows, which would use 3 digits.
4103 Also, added 'n' to the formats that PyOS_ascii_formatd understands,
4104 so that any alterations it does to the resulting string will be
4105 available in stringlib/formatter.h (for float.__format__).
4106
Eric Smith5a3c1352008-02-19 13:21:56 +00004107- Implemented PEP 3101, Advanced String Formatting. This adds a new
4108 builtin format(); a format() method for str and unicode; a
4109 __format__() method to object, str, unicode, int, long, float, and
4110 datetime; the class string.Formatter; and the C API
4111 PyObject_Format().
4112
Georg Brandl3ee81df2008-05-17 18:14:43 +00004113- Fixed several potential crashes, all caused by specially crafted
4114 __del__ methods exploiting objects in temporarily inconsistent
4115 state.
Amaury Forgeot d'Arc632fad32008-02-16 20:55:24 +00004116
Vinay Sajipb7edfc42008-04-02 21:10:23 +00004117- Issue #2115: Important speedup in setting __slot__ attributes. Also
Georg Brandl3ee81df2008-05-17 18:14:43 +00004118 prevent a possible crash: an Abstract Base Class would try to access
4119 a slot on a registered virtual subclass.
Amaury Forgeot d'Arc60d6c7f2008-02-15 21:22:45 +00004120

4122 real or imaginary part.
Christian Heimes2f0da532008-02-15 06:57:08 +00004123
Georg Brandl3ee81df2008-05-17 18:14:43 +00004124- Clear all free lists during a gc.collect() of the highest generation
4125 in order to allow pymalloc to free more arenas. Python may give back
4126 memory to the OS earlier.
Christian Heimes3b718a72008-02-14 12:47:33 +00004127
Georg Brandl3ee81df2008-05-17 18:14:43 +00004128- Issue #2045: Fix an infinite recursion triggered when printing a
4129 subclass of collections.defaultdict, if its default_factory is set
4130 to a bound method.
Amaury Forgeot d'Arcb01aa432008-02-08 00:56:02 +00004131
Christian Heimesf75dbef2008-02-08 00:11:31 +00004132- Fixed a minor memory leak in dictobject.c. The content of the free
4133 list was not freed on interpreter shutdown.
4134
Georg Brandl21e99f42010-03-07 15:23:59 +00004135- Limit free list of method and built-in function objects to 256
Georg Brandl3ee81df2008-05-17 18:14:43 +00004136 entries each.
Christian Heimes6075a822008-02-06 12:44:34 +00004137
Georg Brandl3ee81df2008-05-17 18:14:43 +00004138- Patch #1953: Added ``sys._compact_freelists()`` and the C API
4139 functions ``PyInt_CompactFreeList`` and ``PyFloat_CompactFreeList``
Christian Heimes422051a2008-02-04 18:00:12 +00004140 to compact the internal free lists of pre-allocted ints and floats.
4141
Georg Brandl3ee81df2008-05-17 18:14:43 +00004142- Issue #1983: Fixed return type of fork(), fork1() and forkpty()
4143 calls. Python expected the return type int but the fork familie
4144 returns pi_t.
Christian Heimes951cc0f2008-01-31 23:08:23 +00004145
Georg Brandl3ee81df2008-05-17 18:14:43 +00004146- Issue #1678380: Fix a bug that identifies 0j and -0j when they
4147 appear in the same code unit.

Georg Brandl3ee81df2008-05-17 18:14:43 +00004155- Added ``PyType_ClearCache()`` and ``sys._clear_type_cache`` to clear
4156 the internal lookup cache for ref leak tests.
Christian Heimes908caac2008-01-27 23:34:59 +00004157
Georg Brandl3ee81df2008-05-17 18:14:43 +00004158- Patch #1473257: generator objects gain a gi_code attribute. This is
4159 the same object as the func_code attribute of the function that
4160 produced the generator.
Georg Brandl0cdf9a32008-01-26 14:14:20 +00004161
Georg Brandl3ee81df2008-05-17 18:14:43 +00004162- Issue #1920: "while 0" statements were completely removed by the
4163 compiler, even in the presence of an "else" clause, which is
4164 supposed to be run when the condition is false. Now the compiler
4165 correctly emits bytecode for the "else" suite.
Amaury Forgeot d'Arc31eaafe2008-01-24 22:59:25 +00004166
Guido van Rossumeead05f2008-01-24 18:21:02 +00004167- A few crashers fixed: weakref_in_del.py (issue #1377858);
4168 loosing_dict_ref.py (issue #1303614, test67.py);
4169 borrowed_ref_[34].py (not in tracker).
4170
Vinay Sajipd7cf32e2008-01-24 12:43:33 +00004171- Issue #1069410: The "can't load dll" message box on Windows is
Christian Heimesb2302ba2008-01-23 17:15:06 +00004172 suppressed while an extension is loaded by calling SetErrorMode in
4173 dynload_win.c. The error is still reported properly.
4174
Georg Brandl3ee81df2008-05-17 18:14:43 +00004175- Issue #1915: Python compiles with --enable-unicode=no again. However
Christian Heimes082c9b02008-01-23 14:20:50 +00004176 several extension methods and modules do not work without unicode
4177 support.
4178
Georg Brandl26543b12008-01-21 18:36:51 +00004179- Issue #1882: when compiling code from a string, encoding cookies in the
4180 second line of code were not always recognized correctly.
4181
Georg Brandl14404b62008-01-19 19:27:05 +00004182- Issue #1679: "0x" was taken as a valid integer literal.
4183
Georg Brandl6caad7d2008-01-26 14:19:22 +00004184- Issue #1865: ``bytes`` as an alias for ``str`` and b"" as an alias "" were
Christian Heimes288e89a2008-01-18 18:24:07 +00004185 added.
4186
Christian Heimesc94e2b52008-01-14 04:13:37 +00004187- sys.float_info / PyFloat_GetInfo: The floating point information
4188 object was converted from a dict to a specialized structseq object.
4189
Georg Brandl3ee81df2008-05-17 18:14:43 +00004190- Patch #1816: Added sys.flags structseq. It exposes the status of
4191 most command line arguments and PYTHON* environment variables.
Christian Heimesf31b69f2008-01-14 03:42:48 +00004192
Georg Brandl3ee81df2008-05-17 18:14:43 +00004193- Objects/structseq.c: Implemented new structseq representation. The
4194 patch makes structseqs (e.g. the return value of os.stat) more
4195 readable.
Christian Heimes9c201962008-01-14 03:33:52 +00004196
Georg Brandl3ee81df2008-05-17 18:14:43 +00004197- Patch #1700288: added a type attribute cache that caches method

4206 envvar and sys.dont_write_bytecode attribute. All these can be set
4207 to forbid Python to attempt to write compiled bytecode files.
Georg Brandl2da0fce2008-01-07 17:09:35 +00004208
Georg Brandl3ee81df2008-05-17 18:14:43 +00004209- Improve some exception messages when Windows fails to load an
4210 extension module. Now we get for example '%1 is not a valid Win32

Georg Brandl3ee81df2008-05-17 18:14:43 +00004219 and INF. float("nan"), float("inf") and float("-inf") now work on
4220 every platform with IEEE 754 semantics.
Christian Heimes0a8143f2007-12-18 23:22:54 +00004221
Georg Brandl3ee81df2008-05-17 18:14:43 +00004222- Compiler now generates simpler and faster code for dictionary
4223 literals. The oparg for BUILD_MAP now indicates an estimated
4224 dictionary size. There is a new opcode, STORE_MAP, for adding
4225 entries to the dictionary.

Georg Brandl3ee81df2008-05-17 18:14:43 +00004270 smaller than LONG_MAX. Formerly, it raised an OverflowError. Now,
4271 automatically shifts from ints to longs.
Raymond Hettinger8f669372007-10-03 21:18:11 +00004272
Georg Brandl3ee81df2008-05-17 18:14:43 +00004273- Issue #1686386: Tuple's tp_repr did not take into account the
4274 possibility of having a self-referential tuple, which is possible
4275 from C code. Nor did object's tp_str consider that a type's tp_str
4276 could do something that could lead to an inifinite recursion.
4277 Py_ReprEnter() and Py_EnterRecursiveCall(), respectively, fixed the
4278 issues.

Georg Brandl3ee81df2008-05-17 18:14:43 +00004280- Issue #1164: It was possible to trigger deadlock when using the
4281 'print' statement to write to a file since the GIL was not released
4282 as needed. Now PyObject_Print() does the right thing along with
4283 various tp_print implementations of the built-in types and those in
4284 the collections module.
Brett Cannon01531592007-09-17 03:28:34 +00004285
Georg Brandl3ee81df2008-05-17 18:14:43 +00004286- Issue #1147: Exceptions were directly allowing string exceptions in
4287 their throw() method even though string exceptions no longer
4288 allowed.
Brett Cannon4c20bc42007-09-11 21:02:28 +00004289
Georg Brandl3ee81df2008-05-17 18:14:43 +00004290- Issue #1096: Prevent a segfault from getting the repr of a very
4291 deeply nested list by using the recursion counter.
Brett Cannona0c05512007-09-10 21:38:27 +00004292
Brett Cannon1e534b52007-09-07 04:18:30 +00004293- Issue #1202533: Fix infinite recursion calls triggered by calls to
Georg Brandl3ee81df2008-05-17 18:14:43 +00004294 PyObject_Call() never calling back out to Python code to trigger
4295 recursion depth updates/checks. Required the creation of a static
4296 RuntimeError instance in case normalizing an exception put the
4297 recursion check value past its limit. Fixes crashers
4298 infinite_rec_(1|2|4|5).py.

Neal Norwitz0ac60192007-05-27 04:08:54 +00004313- Add new attribute names for function objects. All the func_* become
Georg Brandl3ee81df2008-05-17 18:14:43 +00004314 __*__ attributes. (Some already existed, e.g., __doc__ and
4315 __name__.)
Neal Norwitz0ac60192007-05-27 04:08:54 +00004316
Neal Norwitz8b2bfbc2007-05-23 06:35:32 +00004317- Add -3 option to the interpreter to warn about features that are
4318 deprecated and will be changed/removed in Python 3.0.
4319
Georg Brandl2134e752007-05-21 20:34:16 +00004320- Patch #1686487: you can now pass any mapping after '**' in function
4321 calls.
4322
Collin Winter62903052007-05-18 23:11:24 +00004323- except clauses may now be spelled either "except E, target:" or
Georg Brandl3ee81df2008-05-17 18:14:43 +00004324 "except E as target:". This is to provide forwards compatibility
4325 with Python 3.0.

Vinay Sajip8549ce32007-05-06 17:53:37 +00004332- When __slots__ are set to a unicode string, make it work the same as
Neal Norwitzcbd9ee62007-04-14 05:25:50 +00004333 setting a plain string, ie don't expand to single letter identifiers.
4334
Raymond Hettinger13936692007-04-11 18:40:58 +00004335- Request #1191699: Slices can now be pickled.
4336
Raymond Hettinger4db5fe92007-04-12 04:10:00 +00004337- Request #1193128: str.translate() now allows a None argument for
4338 translations that only remove characters without re-mapping the
4339 remaining characters.
4340
Georg Brandl5cb76c12007-03-21 09:00:39 +00004341- Patch #1682205: a TypeError while unpacking an iterable is no longer

4345
Guido van Rossum143b5642007-03-23 04:58:42 +00004346- Bug #1683368: The object.__init__() and object.__new__() methods are
4347 now stricter in rejecting excess arguments. The only time when
4348 either allows excess arguments is when it is not overridden and the
4349 other one is. For backwards compatibility, when both are
4350 overridden, it is a deprecation warning (for now; maybe a Py3k
Guido van Rossum234b1ff2007-03-23 19:39:01 +00004351 warning later). Also, type.__init__() insists on the same signature
4352 as supported by type.__new__().
Guido van Rossum143b5642007-03-23 04:58:42 +00004353
Georg Brandl3ee81df2008-05-17 18:14:43 +00004354- Patch #1675423: PyComplex_AsCComplex() now tries to convert an
4355 object to complex using its __complex__() method before falling back
4356 to the __float__() method. Therefore, the functions in the cmath
4357 module now can operate on objects that define a __complex__()
4358 method.

4369 its type.

Georg Brandl7b9c5552007-03-12 14:30:05 +00004376- Bug #1678647: write a newline after printing an exception in any
4377 case, even when converting the value to a string failed.
4378
Georg Brandl871f1bc2007-03-12 13:17:36 +00004379- The dir() function has been extended to call the __dir__() method on
Georg Brandl3ee81df2008-05-17 18:14:43 +00004380 its argument, if it exists. If not, it will work like before. This
4381 allows customizing the output of dir() in the presence of a
4382 __getattr__().

4391 parthensized forms. This means complex(repr(x)) now works instead of
4392 raising a ValueError.
Collin Wintere38051d2007-03-09 20:33:07 +00004393
Georg Brandlaa2321b2007-03-07 00:40:28 +00004394- Patch #703779: unset __file__ in __main__ after running a file. This
Georg Brandl3ee81df2008-05-17 18:14:43 +00004395 makes the filenames the warning module prints much more sensible
4396 when a PYTHONSTARTUP file is used.

Georg Brandl0fca97a2007-03-05 22:28:08 +00004409- Patch #1674228: when assigning a slice (old-style), check for the
4410 sq_ass_slice instead of the sq_slice slot.
4411
Georg Brandl3ee81df2008-05-17 18:14:43 +00004412- When printing an unraisable error, don't print exceptions. before
4413 the name. This duplicates the behavior whening normally printing
4414 exceptions.

5043 exception.

Georg Brandl3ee81df2008-05-17 18:14:43 +00005324- Issue #829951: In the smtplib module, SMTP.starttls() now complies
5325 with RFC 3207 and forgets any knowledge obtained from the server not
5326 obtained from the TLS negotiation itself. Patch contributed by Bill
5327 Fenner.
Gregory P. Smith2b3ba582008-01-17 08:03:17 +00005328
Georg Brandl3ee81df2008-05-17 18:14:43 +00005329- Issue #1339: The smtplib.SMTP class has been refactored a bit such
Gregory P. Smithbde4ae42008-01-17 08:35:49 +00005330 that the SMTP.starttls() caller no longer needs to call ehlo()
5331 beforehand. SMTP.starttls() now raises an exception of the server
Georg Brandl3ee81df2008-05-17 18:14:43 +00005332 does not claim to support starttls. Adds the
5333 SMTP.ehlo_or_helo_if_needed() method. Patch contributed by Bill
5334 Fenner.

5414 complex, tuple, list, dict, set, and frozenset. Formerly, it would
5415 silently miscode subclasses of those types. Now, it raises a
5416 ValueError instead.
Raymond Hettinger12e94202007-11-07 01:13:09 +00005417

Georg Brandl3ee81df2008-05-17 18:14:43 +00005432 time so that opening a database previously created with the DB_DUP
5433 or DB_DUPSORT flag set will keep the proper behavior on subsequent
5434 opens. Specifically: dictionary assignment to a DB object will
5435 replace all values for a given key when the database allows
5436 duplicate values. DB users should use DB.put(k, v) when they want
5437 to store duplicates; not DB[k] = v.
Gregory P. Smithec10a4a2007-11-05 02:32:26 +00005438

5444 characters with ASCII value less than 32. Also, it correctly quotes
5445 dots only if they occur on a single line, as opposed to the previous
5446 behavior of quoting dots if they are the second character of any
5447 line.
Georg Brandl4aef7272007-03-13 22:49:43 +00005448

5770-----
5771
Georg Brandl3ee81df2008-05-17 18:14:43 +00005772- Unified naming convention for free lists and their limits. All free
5773 lists in Object/ are named ``free_list``, the counter ``numfree``
5774 and the upper limit is a macro ``PyName_MAXFREELIST`` inside an
5775 #ifndef block.
Christian Heimes5b970ad2008-02-06 13:33:44 +00005776
Georg Brandl3ee81df2008-05-17 18:14:43 +00005777- ``PySet_Add()`` can now modify a newly created frozenset. Similarly
5778 to ``PyTuple_SetItem``, it can be used to populate a brand new
5779 frozenset; but it does not steal a reference to the added item.

5788
5789- Issue #1534: Added ``PyFloat_GetMax()``, ``PyFloat_GetMin()`` and
5790 ``PyFloat_GetInfo()`` to the float API.
5791
Georg Brandl3ee81df2008-05-17 18:14:43 +00005792- Issue #1521: On 64bit platforms, using PyArgs_ParseTuple with the t#
5793 of w# format code incorrectly truncated the length to an int, even
5794 when PY_SSIZE_T_CLEAN is set. The str.decode method used to return
5795 incorrect results with huge strings.
Georg Brandl6caad7d2008-01-26 14:19:22 +00005796
Georg Brandl3ee81df2008-05-17 18:14:43 +00005797- Issue #1629: Renamed Py_Size, Py_Type and Py_Refcnt to Py_SIZE,

5815- Fix some leftovers from the conversion from int to Py_ssize_t
5816 (relevant to strings and sequences of more than 2**31 items).
5817
5818- Make _PyGILState_NoteThreadState() static, it was not used anywhere
5819 outside of pystate.c and should not be necessary.
5820
Georg Brandl3ee81df2008-05-17 18:14:43 +00005821- ``PyImport_Import`` and ``PyImport_ImportModule`` now always do
5822 absolute imports. In earlier versions they might have used relative
5823 imports under some conditions.
Christian Heimes000a0742008-01-03 22:16:32 +00005824
Georg Brandl3ee81df2008-05-17 18:14:43 +00005825- Added case insensitive comparison methods ``PyOS_stricmp(char*,
5826 char*)`` and ``PyOS_strnicmp(char*, char*, Py_ssize_t)``.
Christian Heimes000a0742008-01-03 22:16:32 +00005827
Georg Brandl3ee81df2008-05-17 18:14:43 +00005828- Bug #1542693: remove semi-colon at end of PyImport_ImportModuleEx

Georg Brandl3ee81df2008-05-17 18:14:43 +00005835- Patch #1706: Drop support for Win9x, WinME and NT4. Python now
5836 requires Windows 2000 or greater. The _WINVER and NTDDI_VERSION
5837 macros are set to Win2k for x86/32bit builds and WinXP for AMD64
5838 builds.
Christian Heimes95d64472008-02-09 19:55:22 +00005839

Georg Brandl3ee81df2008-05-17 18:14:43 +00005853- Removed the macfs module. It had been deprecated since Python 2.5.
5854 This lead to the deprecation of macostools.touched() as it relied
5855 solely on macfs and was a no-op under OS X.
