44 witnessed in test_httpservers.
45
Antoine Pitroufc69af12010-04-24 20:04:58 +000046- Issue #5103: SSL handshake would ignore the socket timeout and block
47 indefinitely if the other end didn't respond.
48
Antoine Pitrou4d3e3722010-04-24 19:57:01 +000049- The do_handshake() method of SSL objects now adjusts the blocking mode of
50 the SSL structure if necessary (as other methods already do).

65 a non-infinite timeout. Also make that method friendlier with applications
66 wanting to continue using the socket in clear-text mode, by disabling
67 OpenSSL's internal readahead. Thanks to Darryl Miles for guidance.
68
Antoine Pitrouc715a9e2010-04-21 19:28:03 +000069- Issue #8484: Load all ciphers and digest algorithms when initializing

93
R. David Murray1a14d3d2010-04-12 16:35:19 +000094- Issue #7585: difflib context and unified diffs now place a tab between
95 filename and date, conforming to the 'standards' they were originally
96 designed to follow. This improves compatibility with patch tools.
97
R. David Murray27ef9372010-04-12 14:26:06 +000098- Issue #7472: Fixed typo in email.encoders module; messages using ISO-2022

131Core and Builtins
132-----------------
133
Philip Jenveyaebbaeb2010-04-06 23:24:45 +0000134- Issue #7301: Add environment variable $PYTHONWARNINGS.
135
Benjamin Peterson3a1dfa22010-04-06 21:50:00 +0000136- Issue #8329: Don't return the same lists from select.select when no fds are
137 changed.
138
Mark Dickinson82791672010-04-06 16:47:55 +0000139- Issue #8259: 1L << (2**31) no longer produces an 'outrageous shift error'
140 on 64-bit machines. The shift count for either left or right shift is
141 permitted to be up to sys.maxsize.
142
Benjamin Peterson4ceeeb02010-04-03 22:48:51 +0000143- Ensure that tokenization of identifiers is not affected by locale.

148
Eric Smithd44b2fc2010-04-02 12:30:56 +0000149- Issue #7994: Issue a PendingDeprecationWarning if object.__format__
150 is called with a non-empty format string. This is an effort to
151 future-proof user code. If a derived class does not currently
152 implement __format__ but later adds its own __format__, it would
153 most likely break user code that had supplied a format string. This
154 will be changed to a DeprecationWaring in Python 3.3 and it will be
155 an error in Python 3.4.
156
Antoine Pitroua57df2c2010-03-31 21:32:15 +0000157- Issue #8268: Old-style classes (not just instances) now support weak
158 references.

Georg Brandlba83f822010-03-14 09:50:54 +0000171 (SIGINT). If an error occurs while importing the site module, the error is
172 printed and Python exits. Initialize the GIL before importing the site
Victor Stinner66644262010-03-10 22:30:19 +0000173 module.

183 using the new attributes `ssl.OPENSSL_VERSION`, `ssl.OPENSSL_VERSION_INFO`
184 and `ssl.OPENSSL_VERSION_NUMBER`.
185
Benjamin Peterson76a23c12010-04-04 23:23:22 +0000186- Issue #8310: Allow dis to examine new style classes.
187
Mark Dickinson8a950712010-04-03 15:47:46 +0000188- Issue #8257: The Decimal construct now accepts a float instance
189 directly, converting that float to a Decimal of equal value:

195
Raymond Hettingera551f312010-04-04 18:34:45 +0000196- the functools module now has a total_ordering() class decorator
Georg Brandl4fabac52010-04-14 08:53:38 +0000197 to simplify the specification of rich comparisons.
Raymond Hettingera551f312010-04-04 18:34:45 +0000198
Raymond Hettingerbb006cf2010-04-04 21:45:01 +0000199- The functools module also adds cmp_to_key() as a tool to transition
Raymond Hettingera551f312010-04-04 18:34:45 +0000200 old-style comparison functions to new-style key-functions.
201
Mark Dickinson7c63eee2010-04-02 22:27:36 +0000202- Issue #8294: The Fraction constructor now accepts Decimal and float
203 instances directly.
204
Mark Dickinsone096e822010-04-02 10:17:07 +0000205- Issue #7279: Comparisons involving a Decimal signaling NaN now
206 signal InvalidOperation instead of returning False. (Comparisons
Mark Dickinsonf3eeca12010-04-02 10:35:12 +0000207 involving a quiet NaN are unchanged.) Also, Decimal quiet NaNs
208 are now hashable; Decimal signaling NaNs remain unhashable.
Mark Dickinsone096e822010-04-02 10:17:07 +0000209
Mark Dickinson99d80962010-04-02 08:53:22 +0000210- Issue #2531: Comparison operations between floats and Decimal

216 argument `-` which tells it to read files to compile from stdin. Each line
217 is read on demand and the named file is compiled immediately. (Original
218 patch by Piotr Ożarowski).
219
220- Issue #3135: Add inspect.getcallargs, which binds arguments to a function
221 like a normal call.
Benjamin Peterson7e213252010-03-30 17:58:13 +0000222
Florent Xicluna58b65662010-03-30 16:29:03 +0000223- Backwards incompatible change: Unicode codepoints line tabulation (0x0B) and
224 form feed (0x0C) are now considered linebreaks, as specified in Unicode
225 Standard Annex #14. See issue #7643.

229 a Fractions instance now raise TypeError instead of returning
230 True/False. This makes Fraction <=> complex comparisons consistent with
231 int <=> complex, float <=> complex, and complex <=> complex comparisons.
232

244 now silenced.
245
Florent Xicluna9e7a4c92010-03-22 16:07:38 +0000246- Issue #7703: ctypes supports both buffer() and memoryview(). The former is

Georg Brandlba83f822010-03-14 09:50:54 +0000299- Issue #7143: email: ``get_payload()`` used to strip any trailing newline from
300 a base64 transfer-encoded payload *after* decoding it; it no longer does.

Mark Dickinson4846a8e2010-04-03 14:05:10 +0000328- Issue #8300: When passing a non-integer argument to struct.pack with any
329 integer format code, struct.pack first attempts to convert the non-integer
330 using its __index__ method. If that method is non-existent or raises
331 TypeError it goes on to try the __int__ method, as described below.
332
Georg Brandlba83f822010-03-14 09:50:54 +0000333- Issue #1530559: When passing a non-integer argument to struct.pack with *any*
334 integer format code (one of 'bBhHiIlLqQ'), struct.pack attempts to use the
335 argument's __int__ method to convert to an integer before packing. It also
336 produces a DeprecationWarning in this case. (In Python 2.6, the behaviour
337 was inconsistent: __int__ was used for some integer codes but not for others,
338 and the set of integer codes for which it was used differed between native
339 packing and standard packing.)

Georg Brandlba83f822010-03-14 09:50:54 +0000544- Issue #7712: test_support gained a new ``temp_cwd`` context manager which is
545 now also used by regrtest to run all the tests in a temporary directory. The
546 original CWD is saved in ``test.test_support.SAVEDCWD``. Thanks to Florent
547 Xicluna who helped with the patch.

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

Antoine Pitroud840e512010-02-04 20:20:18 +0000629- Issue #4772: Raise a ValueError when an unknown Bluetooth protocol is
Georg Brandlba83f822010-03-14 09:50:54 +0000630 specified, rather than fall through to AF_PACKET (in the ``socket`` module).

Antoine Pitrouf3fa0742010-01-31 22:26:04 +0000636- Issue #6939: Fix file I/O objects in the `io` module to keep the original
Georg Brandlba83f822010-03-14 09:50:54 +0000637 file position when calling `truncate()`. It would previously change the file
638 position to the given argument, which goes against the tradition of
Antoine Pitrouf3fa0742010-01-31 22:26:04 +0000639 ftruncate() and other truncation APIs. Patch by Pascal Chambon.
640
Benjamin Petersone06f7112010-01-28 02:15:02 +0000641- UserDict is now a new-style class.

644 class used to represent files stored inside an archive. The new
645 implementation is significantly faster and can be wrapped in a
646 ``io.BufferedReader`` object for more speedups. It also solves an issue
647 where interleaved calls to ``read()`` and ``readline()`` give wrong results.
648 Patch by Nir Aides.

656 when the release file is empty.
Benjamin Petersona43f34c2010-01-25 03:31:13 +0000657
Georg Brandlba83f822010-03-14 09:50:54 +0000658- Issue #7748: Since unicode values are supported for some metadata options in
659 Distutils, the DistributionMetadata get_* methods will now return an utf-8
660 encoded string for them. This ensures that the upload and register commands
661 send the correct values to PyPI without any error.

737
Georg Brandlba83f822010-03-14 09:50:54 +0000738- The ``__complex__()`` method is now looked up on the class of instances to
739 make it consistent with other special methods.

Antoine Pitrou5b7139a2010-01-02 21:12:58 +0000741- Issue #7462: Implement the stringlib fast search algorithm for the `rfind`,
742 `rindex`, `rsplit` and `rpartition` methods. Patch by Florent Xicluna.
743
Mark Dickinson1b34d252010-01-01 17:27:30 +0000744- Issue #5080: A number of functions and methods previously produced a
Georg Brandlba83f822010-03-14 09:50:54 +0000745 DeprecationWarning when passed a float argument where an integer was expected.
746 These functions and methods now raise TypeError instead. The majority of the
747 effects of this change are in the extension modules, but some core functions
748 and methods are affected: notably the 'chr', 'range' and 'xrange' builtins,
749 and many unicode/str methods.

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

773
Georg Brandlba83f822010-03-14 09:50:54 +0000774 These executables now work properly with the arch(1) command: ``arch -ppc
775 python`` will start a universal binary version of python in PPC mode (unlike
776 previous releases).

Georg Brandlba83f822010-03-14 09:50:54 +0000799 renaming of `cPickle` to `pickle`. The warning was annoying since there's no

916 to 'g' for large values.
Amaury Forgeot d'Arcd7288712009-12-01 21:51:04 +0000917

919 1e50 in absolute value.
Mark Dickinson9dd5e162009-11-23 20:54:09 +0000920
Georg Brandlba83f822010-03-14 09:50:54 +0000921- Remove restrictions on precision when formatting floats. E.g., "%.120g" %

930 10.6.
Ronald Oussoren315cd0c2009-11-19 16:25:21 +0000931
Georg Brandlba83f822010-03-14 09:50:54 +0000932- Issue #7117: ``repr(x)`` for a float x returns a result based on the shortest
933 decimal string that's guaranteed to round back to x under correct rounding
934 (with round-half-to-even rounding mode). Previously it gave a string based on
935 rounding x to 17 decimal digits. repr(x) for a complex number behaves
936 similarly. On platforms where the correctly-rounded strtod and dtoa code is
937 not supported (see below), repr is unchanged.
Mark Dickinsonb678de82009-11-19 18:41:49 +0000938
Georg Brandlba83f822010-03-14 09:50:54 +0000939- Issue #7117: On almost all platforms: float-to-string and string-to-float
940 conversions within Python are now correctly rounded. Places these conversions
941 occur include: str for floats and complex numbers; the float and complex
942 constructors; old-style and new-style numeric formatting; serialization and
943 deserialization of floats and complex numbers using marshal, pickle and json;
944 parsing of float and imaginary literals in Python code; Decimal-to-float
945 conversion.
Mark Dickinsonb678de82009-11-19 18:41:49 +0000946
Georg Brandlba83f822010-03-14 09:50:54 +0000947 The conversions use a Python-adapted version of David Gay's well-known dtoa.c,
948 providing correctly-rounded strtod and dtoa C functions. This code is
949 supported on Windows, and on Unix-like platforms using gcc, icc or suncc as
950 the C compiler. There may be a small number of platforms on which correct
951 operation of this code cannot be guaranteed, so the code is not used: notably,
952 this applies to platforms where the C double format is not IEEE 754 binary64,
953 and to platforms on x86 hardware where the x87 FPU is set to 64-bit precision
954 and Python's configure script is unable to determine how to change the FPU
955 precision. On these platforms conversions use the platform strtod and dtoa,
956 as before.

Georg Brandlba83f822010-03-14 09:50:54 +0000958- Issue #7117: Backport round implementation from Python 3.x. ``round()`` now
959 uses the correctly-rounded string <-> float conversions described above (when
960 available), and so produces correctly rounded results that will display nicely
961 under the float repr. There are two related small changes: (1) round now
962 accepts any class with an ``__index__()`` method for its second argument (but
963 no longer accepts floats for the second argument), and (2) an excessively
964 large second integer argument (e.g., ``round(1.234, 10**100)``) no longer
965 raises an exception.

Georg Brandlba83f822010-03-14 09:50:54 +0000969- Fix several issues with ``compile()``. The input can now contain Windows and

Georg Brandlba83f822010-03-14 09:50:54 +00001112- Issue #5920: For ``float.__format__()``, change the behavior with the empty
1113 presentation type (that is, not one of 'e', 'f', 'g', or 'n') to be like 'g'
1114 but with at least one decimal point and with a default precision
1115 of 12. Previously, the behavior the same but with a default precision of 6.
1116 This more closely matches ``str()``, and reduces surprises when adding
1117 alignment flags to the empty presentation type. This also affects the new
1118 complex.__format__ in the same way.

1302 ``offsetof(PyStringObject, ob_sval) + 1`` when allocating memory for str
1303 instances. On a typical machine this saves 3 bytes of memory (on average) per

1309
Georg Brandlba83f822010-03-14 09:50:54 +00001310- Issue #3689: The list reversed iterator now supports __length_hint__ instead

1315
Georg Brandlba83f822010-03-14 09:50:54 +00001316- Issue #4233: Changed semantic of ``_fileio.FileIO``'s ``close()`` method on
1317 file objects with closefd=False. The file descriptor is still kept open but
1318 the file object behaves like a closed file. The ``FileIO`` object also got a
1319 new readonly attribute ``closefd``.

1338
Benjamin Peterson399b1fe2008-10-25 02:53:28 +00001339- Using ``nonlocal`` as a variable name will now raise a Py3k SyntaxWarning

Georg Brandlba83f822010-03-14 09:50:54 +00001342- On windows, ``os.chdir()`` given unicode was not working if
1343 GetCurrentDirectoryW returned a path longer than MAX_PATH. (But It's doubtful
1344 this code path is really executed because I cannot move to such directory on
1345 win2k)

Georg Brandlba83f822010-03-14 09:50:54 +00001347- Issue #4069: When ``set.remove(element)`` is used with a set element, the
1348 element is temporarily replaced with an equivalent frozenset. But the
1349 eventual KeyError would always report the empty ``frozenset()`` as the missing
1350 key. Now it correctly refers to the initial element.

1369
Walter Dörwalded960ac2009-05-03 22:36:33 +00001370- Issue #5108: Handle %s like %S and %R in PyUnicode_FromFormatV(): Call
1371 PyUnicode_DecodeUTF8() once, remember the result and output it in a second
1372 step. This avoids problems with counting UTF-8 bytes that ignores the effect
1373 of using the replace error handler in PyUnicode_DecodeUTF8().
1374
Walter Dörwald726ba8e2009-05-06 14:32:35 +00001375- Issue #3739: The unicode-internal encoder now reports the number of characters
1376 consumed like any other encoder (instead of the number of bytes).
1377
Georg Brandlba83f822010-03-14 09:50:54 +00001378- Issue #2422: When compiled with the ``--with-valgrind`` option, the pymalloc
1379 allocator will be automatically disabled when running under Valgrind. This
1380 gives improved memory leak detection when running under Valgrind, while taking
1381 advantage of pymalloc at other times.

Antoine Pitrou4698d992009-05-31 14:20:14 +00002628- Issue #6152: New option '-j'/'--multiprocess' for regrtest allows running
2629 regression tests in parallel, shortening the total runtime.

Georg Brandlba83f822010-03-14 09:50:54 +00002631- Issue #5354: New test support function import_fresh_module() makes it easy to
2632 import both normal and optimised versions of modules. test_heapq and
2633 test_warnings have been adjusted to use it, tests for other modules with both
2634 C and Python implementations in the stdlib can be adjusted to use it over
2635 time.

Georg Brandlba83f822010-03-14 09:50:54 +00002643- regrtest no longer treats ImportError as equivalent to SkipTest. Imports that
2644 should cause a test to be skipped are now done using import_module from test
2645 support, which does the conversion.

Martin v. Löwis9fa5a282008-09-11 06:53:30 +00002746- Issue #3642: Suppress warning in obmalloc when size_t is larger than uint.
2747
Amaury Forgeot d'Arc05e34492008-09-10 22:04:45 +00002748- Issue #3743: In a few places, PY_FORMAT_SIZE_T was incorrectly used with
2749 PyString_FromFormat or PyErr_Format to display size_t values. The macro
2750 PY_FORMAT_SIZE_T is designed to select the correct format for the OS
2751 ``printf`` function, whereas PyString_FromFormat has an independent
2752 implementation and uses "%zd" on all platforms for size_t values.
2753 This makes a difference on win64, where ``printf`` needs "%Id" to display
2754 64bit values.

Benjamin Peterson97179b02008-09-09 20:55:01 +00002756- Issue #3634: _weakref.ref(Exception).__init__() gave invalid return value on

Antoine Pitroud4ae97b2008-08-29 18:39:48 +00002771 was correctly parsed but parsing of subsequent arguments failed.
2772
Vinay Sajip35e3b032008-09-01 14:33:59 +00002773- Issue #2534: speed up isinstance() and issubclass() by 50-70%, so as to
Antoine Pitrou0668c622008-08-26 22:42:08 +00002774 match Python 2.5 speed despite the __instancecheck__ / __subclasscheck__
2775 mechanism. In the process, fix a bug where isinstance() and issubclass(),
2776 when given a tuple of classes as second argument, were looking up
2777 __instancecheck__ / __subclasscheck__ on the tuple rather than on each
2778 type object.

2922Core and Builtins
2923-----------------
2924
Guido van Rossumf8402962008-08-20 15:01:50 +00002925- Issue #1878: Remove Py_TPFLAGS_HAVE_VERSION_TAG from
2926 Py_TPFLAGS_DEFAULT when not building the core. This means 3rd party
2927 extensions do not automatically benefit from the class attribute
2928 cache; they will have to explicitly add Py_TPFLAGS_HAVE_VERSION_TAG
2929 to their tp_flags field if they care. This is a backwards
2930 compatibility feature; in 3.0, all types will use the cache by
2931 default.
2932
Benjamin Petersonf647dc12008-08-20 01:27:30 +00002933- Keyword arguments can now follow starred arguments. (``f(a, *args,
2934 keyword=23)`` is now valid syntax.)
2935
Thomas Heller0ad5ae02008-08-19 19:25:04 +00002936- ctypes function pointers that are COM methods have a boolean True
2937 value again.
2938
Martin v. Löwisf91d46a2008-08-12 14:49:50 +00002939- Issue #3139: Make buffer-interface thread-safe wrt. PyArg_ParseTuple,
2940 by denying s# to parse objects that have a releasebuffer procedure,
2941 and introducing s*.
2942
Georg Brandl1e13ea92008-08-11 09:07:59 +00002943- Issue #3537: Fix an assertion failure when an empty but presized dict
2944 object was stored in the freelist.
2945
Mark Dickinsonb6467572008-08-04 21:30:09 +00002946- Issue #1481296: Make long(float('nan')) and int(float('nan')) raise
2947 ValueError consistently across platforms.
2948
Amaury Forgeot d'Arc39fd6722008-07-31 21:28:03 +00002949- Issue #3479: On platforms where sizeof(int) is smaller than sizeof(long)
2950 (64bit Unix, for example), unichr() would truncate its argument and return
2951 u'\x00' for unichr(2**32). Now it properly raises an OverflowError.
2952
Neal Norwitze7d8be82008-07-31 17:17:14 +00002953- Apply security patches from Apple.
2954
Amaury Forgeot d'Arc246daed2008-07-31 00:42:16 +00002955- Issue #2542: Now that issubclass() may call arbitrary code, ensure that
2956 PyErr_ExceptionMatches returns 0 when an exception occurs there.
2957
Antoine Pitrou92f82162008-07-25 22:22:08 +00002958- Issue #1819: function calls with several named parameters are now on
2959 average 35% faster (as measured by pybench).
2960
Amaury Forgeot d'Arce4921fe2008-07-21 22:00:38 +00002961- Issue #2378: An unexpected UnboundLocalError or NameError could appear when
2962 the python debugger steps into a class statement: the free variables (local
2963 variables defined in an outer scope) would be deleted from the outer scope.
2964
Gregory P. Smith0470bab2008-07-22 04:46:32 +00002965- Issue #2620: Overflow checking when allocating or reallocating memory
2966 was not always being done properly in some python types and extension
2967 modules. PyMem_MALLOC, PyMem_REALLOC, PyMem_NEW and PyMem_RESIZE have
2968 all been updated to perform better checks and places in the code that
2969 would previously leak memory on the error path when such an allocation
2970 failed have been fixed.

2973-------
2974
Hirokazu Yamamoto838c79f2008-08-20 13:14:07 +00002975- Issue #3612: Added some missing basic types in ctypes.wintypes.
2976
Benjamin Petersone977ad42008-08-20 01:42:01 +00002977- The methods ``is_in_tuple()``, ``is_vararg()``, and ``is_keywordarg()`` of
2978 symtable.Symbol have been deprecated for removal in 3.0 and the next release.
2979
Amaury Forgeot d'Arc351ffb82008-08-18 19:23:47 +00002980- Issue #2234: distutils failed for some versions of the cygwin compiler. The
2981 version reported by these tools does not necessarily follow the python
2982 version numbering scheme, so the module is less strict when parsing it.
2983
Nick Coghlanf70385a2008-08-18 12:42:46 +00002984- Issue #2235: Added Py3k warnings for types which will become unhashable
2985 under the stricter __hash__ inheritance rules in 3.0. Several types
2986 which did not meet the rules for hash invariants and were already
2987 unhashable in 3.0 have now been explicitly flagged as unhashable in
2988 2.6 as well (collections.Mapping, collections.Set, unittest.TestSuite,
2989 xml.dom.minidom.NamedNodeMap, numbers.Number, UserList.UserList)
2990
Brett Cannon88f801d2008-08-18 00:46:22 +00002991- Update __all__ for cookielib, csv, os, urllib2, and weakref to include things
2992 imported into the module but exposed as part of the module's API.
2993
Brett Cannon7b96f072008-08-18 00:41:11 +00002994- Remove an unneeded import of abc.ABCMeta from 'inspect'.
2995
Brett Cannon46225e72008-08-18 00:36:52 +00002996- Remove unneeded imports of 'sys' and 'warnings' from 'io'.
2997
Brett Cannon25c9d6a2008-08-17 22:10:11 +00002998- Remove unneeded imports of 'warnings' from shelve, filecmp, and dummy_thread.
2999
Hirokazu Yamamoto41a81eb2008-08-17 13:10:46 +00003000- Issue #3575: Incremental decoder's decode function now takes bytearray
3001 by using 's*' instead of 't#'.
3002
Mark Dickinson3e4caeb2009-02-21 20:27:01 +00003003- Issue #2222: Fixed reference leak when occurred os.rename()
Hirokazu Yamamoto7f30a682008-08-17 09:46:56 +00003004 fails unicode conversion on 2nd parameter. (windows only)
3005
Facundo Batista94f243a2008-08-17 03:38:39 +00003006- Issue 2464. urllib2 now supports a malformation in the URL received
3007 in a redirect.
3008
Brett Cannonabe423e2008-08-16 21:47:07 +00003009- Silence the DeprecationWarning raised when importing mimetools in
Brett Cannon721b1452008-08-16 22:00:27 +00003010 BaseHTTPServer, cgi (and rfc822), httplib.
Brett Cannonabe423e2008-08-16 21:47:07 +00003011
Facundo Batistaeb90b782008-08-16 14:44:07 +00003012- Issue #2776: fixed small issue when handling an URL with double slash
3013 after a 302 response in the case of not going through a proxy.
3014
Antoine Pitroub90a8be2008-08-15 21:03:21 +00003015- Issue #2676: in the email package, content-type parsing was hanging on
3016 pathological input because of quadratic or exponential behaviour of a
3017 regular expression.
3018
Antoine Pitrou11ec65d2008-08-14 21:04:30 +00003019- Issue #3476: binary buffered reading through the new "io" library is now
3020 thread-safe.
3021
Brett Cannonbf3157b2008-08-14 05:00:03 +00003022- Silence the DeprecationWarning of rfc822 when it is imported by mimetools
3023 since mimetools itself is deprecated. Because modules are cached, all
3024 subsequent imports of rfc822 will not raise a visible DeprecationWarning.
3025
Antoine Pitrou9fcd4b32008-08-11 17:21:36 +00003026- Issue #3134: shutil referenced undefined WindowsError symbol.
3027
Robert Schuppenies14646332008-08-10 11:01:53 +00003028- Issue #1342811: Fix leak in Tkinter.Menu.delete. Commands associated to
3029 menu entries were not deleted.
3030
Brett Cannon83e81842008-08-09 23:30:55 +00003031- Copied the implementation of reduce() to _functools.reduce() to have a
3032 version that did not raise a DeprecationWarning under -3.
3033
Antoine Pitrou76b8bee2008-08-09 17:27:23 +00003034- Issue #3205: When iterating over a BZ2File fails allocating memory, raise
3035 a MemoryError rather than silently stop the iteration.
3036
Guido van Rossum59ce9012008-08-09 14:55:34 +00003037- Issue #3487: sre "bytecode" validator. Passing invalid "re-bytecode"
3038 to _sre.compile() will now be rejected. This should not affect anybody
3039 since the re.compile() function never generates invalid re-bytecode.
3040
Skip Montanaroa032bf42008-08-08 22:52:51 +00003041- Issue #3436: Make csv.DictReader's fieldnames attribute a property so that
3042 upon first access it can be automatically initialized from the csv file if
3043 it wasn't initialized during instantiation.
3044
Brett Cannon3aa2a492008-08-06 22:28:09 +00003045- Issue #2338: Create imp.reload() to help with transitioning to Python 3.0 as
3046 the reload() built-in has been removed.
3047
Brett Cannon7e30b672008-08-04 21:52:25 +00003048- Changed code in the following modules/packages to remove warnings raised
Brett Cannonc1b76e42008-08-09 23:06:16 +00003049 while running under the ``-3`` flag: aifc, asynchat, asyncore, bdb, bsddb,
Brett Cannon047e4a92008-08-17 04:16:04 +00003050 ConfigParser, cookielib, csv, difflib, distutils, DocXMLRPCServer, email,
3051 filecmp, fileinput, inspect, logging, modulefinder, pdb, pickle, profile,
3052 pstats, pydoc, re, rlcompleter, SimpleXMLRPCServer, shelve, socket,
3053 subprocess, sqlite3, tarfile, Tkinter, test.test_support, textwrap,
3054 threading, tokenize, traceback, urlparse, wsgiref, xml, xmlrpclib.
Brett Cannon7e30b672008-08-04 21:52:25 +00003055
Lars Gustäbel727bd0b2008-08-02 11:26:39 +00003056- Issue #3039: Fix tarfile.TarFileCompat.writestr() which always
3057 raised an AttributeError.
3058
Benjamin Peterson01a24322008-07-28 23:35:27 +00003059- Issue #2523: Fix quadratic behaviour when read()ing a binary file without
Antoine Pitroude781a42008-08-09 12:43:23 +00003060 asking for a specific length. This problem only affected files opened
3061 using the new "io" module, not the built-in open() function.
Benjamin Peterson01a24322008-07-28 23:35:27 +00003062
Mark Dickinsonfe84cce2008-07-27 06:39:07 +00003063- Issue #3449: Update decimal module to use most recent specification
3064 (v. 1.68) and tests (v. 2.58) from IBM.
3065
Skip Montanarof9ac43f2008-07-27 00:50:41 +00003066- Issue 3437: Bug fix in robotparser parsing of Allow: lines.
3067
Raymond Hettinger8c664e82008-07-25 18:43:33 +00003068- Issue 1592: Improve error reporting when operations are attempted
3069 on a closed shelf.

3072
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00003073- Issue #3120: On 64-bit Windows the subprocess module was truncating handles.
3074
3075- Issue #3303: Fix a crash in locale.strcoll() when calling it with
3076 invalid arguments.
3077
3078- Issue #3302: Fix several crashes when calling locale's gettext functions
3079 with None arguments.
3080
3081- Issue #3389: Allow resolving dotted names for handlers in logging
3082 configuration files.
3083
3084- Deprecate the sunaudio module for removal in Python 3.0.
3085
Antoine Pitrou5fdfa3e2008-07-25 19:42:26 +00003086- Issue #3394: zipfile.writestr sets external attributes when passed a
3087 file name rather than a ZipInfo instance, so files are extracted with
3088 mode 0600 rather than 000 under Unix.
3089
Gregory P. Smitha36f8fe2008-08-04 00:13:29 +00003090- Issue #1857: subprocess.Popen.poll gained an additional _deadstate keyword
3091 argument in python 2.5, this broke code that subclassed Popen to include its
3092 own poll method. Fixed my moving _deadstate to an _internal_poll method.

3100-------------
3101
Nick Coghlan6e8fef02008-08-18 13:14:22 +00003102- Issue #2235: the C API function PyObject_HashNotImplemented and its
3103 interaction with the tp_hash slot (added in 2.6b2) are now documented
3104
Nick Coghlan2a0c2b12008-08-04 12:47:17 +00003105- Issue #643841: The language reference now provides more detailed
3106 coverage of the lookup process for special methods. The disclaimers
3107 regarding lack of coverage of new-style classes have also been
3108 removed, since the coverage is now fairly reasonable.

3117-----------------
3118
Georg Brandl3e483f62008-07-16 22:57:41 +00003119- Issue #3156: Fix inconsistent behavior of the bytearray type: all
3120 its methods now allow for items objects that can be converted to
3121 an integer using operator.index().
3122
Mark Dickinson64b7e502008-07-16 09:40:03 +00003123- Issue #3360: Fix incorrect parsing of '020000000000.0', which
3124 produced a ValueError instead of giving the correct float.
3125
Eric Smitha5fa5a22008-07-16 00:11:49 +00003126- Issue #3083: Add alternate (#) formatting for bin, oct, hex output
3127 for str.format(). This adds the prefix 0b, 0o, or 0x, respectively.
3128
Mark Dickinson7103aa42008-07-15 19:08:33 +00003129- Issue #3008: the float type has a new instance method 'float.hex'
3130 and a new class method 'float.fromhex' to convert floating-point
3131 numbers to and from hexadecimal strings, respectively.
3132
Nick Coghlan6d6bd442008-07-15 15:40:22 +00003133- Issue #2235: __hash__ is once again inherited by default. To allow
3134 collections.Hashable to remain meaningful in the presence of the
3135 default hash implementation (object.__hash__), it is now possible
3136 to explicit block inheritance of hash by setting __hash__=None at
3137 the Python level, or tp_hash=PyObject_HashNotImplemented at the C
3138 level.
3139
Nick Coghlanb028f502008-07-13 14:52:36 +00003140- Issue #3221: Issue a RuntimeWarning instead of raising SystemError if
3141 the parent module cannot be found while performing an absolute import.
3142 This means that an incorrectly defined __package__ attribute will
3143 now only prevent relative imports in that module rather than causing
3144 all imports from that module to fail.
3145
Nick Coghlan14ff9942008-07-08 14:21:42 +00003146- Issue #2517: Allow unicode messages in Exceptions again by correctly
3147 bypassing the instance dictionary when looking up __unicode__ on
3148 new-style classes.
3149
Amaury Forgeot d'Arcbdd941f2008-07-01 20:38:04 +00003150- Issue #3242: Fix a crash inside the print statement, if sys.stdout is
3151 set to a custom object whose write() method happens to install
3152 another file in sys.stdout.
3153
Amaury Forgeot d'Arc1f40c8a2008-06-30 22:42:40 +00003154- Issue #3088: Corrected a race condition in classes derived from
3155 threading.local: the first member set by a thread could be saved in
3156 another thread's dictionary.
3157
Mark Dickinson1ec2fcd2008-06-20 14:53:43 +00003158- Issue #3004: Minor change to slice.indices(): the start and stop
3159 arguments are now treated identically, making the behaviour easier
3160 to describe and understand. For example, slice(None, -10,
3161 1).indices(9) now returns (0, 0, 1) instead of (0, -1, 1), and
3162 slice(None, 10, -1).indices(10) returns (9, 9, -1) instead of (9,
3163 10, -1).
3164
Georg Brandl278fc502008-07-19 12:46:12 +00003165- Issue #3219: Calling a function with repeated keyword arguments,
3166 f(a=2, a=23), would not cause a syntax error. This was a regression
3167 from 2.4 caused by the switch to the new compiler.
Benjamin Peterson175e4d92008-07-01 19:34:52 +00003168
Georg Brandl278fc502008-07-19 12:46:12 +00003169- Issue #2862: Make int and float freelist management consistent with
3170 other freelists. Changes their CompactFreeList apis into
3171 ClearFreeList apis and calls them via gc.collect().

3175
Thomas Heller57adf222008-08-14 19:10:48 +00003176- Issue #3554: ctypes.string_at and ctypes.wstring_at did call Python
3177 api functions without holding the GIL, which could lead to a fatal
3178 error when they failed.
3179
Martin v. Löwisaabf4042008-08-02 07:20:25 +00003180- Issue #799428: Fix Tkinter.Misc._nametowidget to unwrap Tcl command objects.

Jesse Noller13e9d582008-07-16 14:32:36 +00003188- Issue #3125: Remove copy_reg in multiprocessing and replace it with
3189 ForkingPickler.register() to resolve conflict with ctypes.
3190
Vinay Sajip51e65192008-07-18 09:01:10 +00003191- Issue #3090: Fixed ARCHFLAGS parsing on OS/X

Thomas Heller880f5292008-07-15 19:39:38 +00003193- Issue #3313: Fixed a crash when a failed dlopen() call does not set
3194 a valid dlerror() message.
3195
Thomas Heller2bad6572008-07-15 17:19:50 +00003196- Issue #3258: Fixed a crash when a ctypes POINTER type to an
3197 incomplete structure was created.
3198
Brett Cannon3d0b9f02008-07-13 01:15:07 +00003199- Issue #3339: dummy_thread.acquire() should not return None.
3200
Raymond Hettingerb01713e2008-07-10 14:34:57 +00003201- Issue #3285: Fractions from_float() and from_decimal() accept Integral arguments.
3202
Andrew M. Kuchlingcc3f2b12008-07-10 14:43:31 +00003203- Issue #3301: Bisect module behaved badly when lo was negative.
Raymond Hettinger3cd1e422008-07-10 14:03:19 +00003204
Amaury Forgeot d'Arc0f7cddc2008-07-06 21:34:39 +00003205- Issue #839496: SimpleHTTPServer used to open text files in text mode. This is
3206 both unnecessary (HTTP allows text content to be sent in several forms) and
Andrew M. Kuchlingcc3f2b12008-07-10 14:43:31 +00003207 wrong because the actual transmitted size could differ from the
Amaury Forgeot d'Arc0f7cddc2008-07-06 21:34:39 +00003208 content-length. The problem had been corrected in the 2.4 branch, but never

3616 mode or even as a 4-way universal binary (that is, PPC, i386,
Georg Brandl5cc774e2008-06-11 20:28:06 +00003617 PPC64 and x86_64 support in one binary).
Ronald Oussoren5640ce22008-06-05 12:58:24 +00003618
3619 This is controlled by the configure argument ``--with-universal-archs``:
3620
3621 - ``--with-universal-archs=all``: install 4-way universal
3622
3623 - ``--with-universal-archs=32-bit``: install 2-way universal, 32-bit (the default)
3624
3625 - ``--with-universal-archs=64-bit``: install 2-way universal, 64-bit
3626
3627 This option should be used in combination with ``--enable-universalsdk=``.
3628
3629 NOTE: 64-bit and 4-way builds are only suppported on Mac OS X 10.5 (or later).

Georg Brandl3ee81df2008-05-17 18:14:43 +00003679- Issue #1631171: Re-implement the 'warnings' module in C (the
3680 original Python code has been kept as backup). This will allow for
3681 using the 'warning's machinery in such places as the parser where
3682 use of pure Python code is not possible. Both the ``showarning()``
3683 and ``formatwarning()`` gain an optional 'line' argument which is
3684 not called by default for backwards-compatibility reasons. Setting
3685 ``warnings.showwarning()`` to an implementation that lacks support
3686 for the ``line`` argument will raise a DeprecationWarning.

Gregory P. Smithd59fefb2008-04-22 08:11:33 +00003711- The getpass module has been improved on Unix. It now uses /dev/tty
3712 by default and uses stderr instead of stdout. A GetPassWarning is
3713 issued when input echo cannot be controlled.

Georg Brandl3ee81df2008-05-17 18:14:43 +00003749- Issue #2550: The approach used by client/server code for obtaining
3750 ports to listen on in network-oriented tests has been refined in an
3751 effort to facilitate running multiple instances of the entire
3752 regression test suite in parallel without issue.
3753 test_support.bind_port() has been fixed such that it will always
3754 return a unique port -- which wasn't always the case with the
3755 previous implementation, especially if socket options had been set
3756 that affected address reuse (i.e. SO_REUSEADDR, SO_REUSEPORT). The
3757 new implementation of bind_port() will actually raise an exception
3758 if it is passed an AF_INET/SOCK_STREAM socket with either the
3759 SO_REUSEADDR or SO_REUSEPORT socket option set. Furthermore, if
3760 available, bind_port() will set the SO_EXCLUSIVEADDRUSE option on
3761 the socket it's been passed. This currently only applies to
3762 Windows. This option prevents any other sockets from binding to the
3763 host/port we've bound to, thus removing the possibility of the
3764 'non-deterministic' behaviour, as Microsoft puts it, that occurs
3765 when a second SOCK_STREAM socket binds and accepts to a host/port
3766 that's already been bound by another socket. The optional preferred
3767 port parameter to bind_port() has been removed. Under no
3768 circumstances should tests be hard coding ports!
3769
3770 test_support.find_unused_port() has also been introduced, which will
3771 pass a temporary socket object to bind_port() in order to obtain an
3772 unused port. The temporary socket object is then closed and
3773 deleted, and the port is returned. This method should only be used
3774 for obtaining an unused port in order to pass to an external program
3775 (i.e. the -accept [port] argument to openssl's s_server mode) or as
3776 a parameter to a server-oriented class that doesn't give you direct
3777 access to the underlying socket used.
3778
3779 Finally, test_support.HOST has been introduced, which should be used
3780 for the host argument of any relevant socket calls (i.e. bind and
3781 connect).

3789 suite to run in parallel without issue.

4055Core and builtins
4056-----------------
4057
Fred Drakea8ee94b2008-03-01 02:45:07 +00004058- Issue #2051: pyc and pyo files are no longer created with permission
Barry Warsaw52973612008-03-01 02:23:38 +00004059 644. The mode is now inherited from the py file.
Christian Heimes40346852008-02-23 17:52:07 +00004060
Georg Brandlad61bc82008-02-23 15:11:18 +00004061- Issue #2067: file.__exit__() now calls subclasses' close() method.
4062
4063- Patch #1759: Backport of PEP 3129 class decorators.
Christian Heimes5224d282008-02-23 15:01:05 +00004064
Vinay Sajipb7edfc42008-04-02 21:10:23 +00004065- Issue #1881: An internal parser limit has been increased. Also see
Facundo Batistafc2d0102008-02-23 12:01:13 +00004066 issue 215555 for a discussion.
4067
Eric Smitha73fbe72008-02-23 03:09:44 +00004068- Added the future_builtins module, which contains hex() and oct().
4069 These are the PEP 3127 version of these functions, designed to be
4070 compatible with the hex() and oct() builtins from Python 3.0. They
4071 differ slightly in their output formats from the existing, unchanged
4072 Python 2.6 builtins. The expected usage of the future_builtins
4073 module is:
4074 from future_builtins import hex, oct
4075
Eric Smith7ef40bf2008-02-20 23:34:22 +00004076- Issue #1600: Modifed PyOS_ascii_formatd to use at most 2 digit
4077 exponents for exponents with absolute value < 100. Follows C99
4078 standard. This is a change on Windows, which would use 3 digits.
4079 Also, added 'n' to the formats that PyOS_ascii_formatd understands,
4080 so that any alterations it does to the resulting string will be
4081 available in stringlib/formatter.h (for float.__format__).
4082
Eric Smith5a3c1352008-02-19 13:21:56 +00004083- Implemented PEP 3101, Advanced String Formatting. This adds a new
4084 builtin format(); a format() method for str and unicode; a
4085 __format__() method to object, str, unicode, int, long, float, and
4086 datetime; the class string.Formatter; and the C API
4087 PyObject_Format().
4088
Georg Brandl3ee81df2008-05-17 18:14:43 +00004089- Fixed several potential crashes, all caused by specially crafted
4090 __del__ methods exploiting objects in temporarily inconsistent
4091 state.
Amaury Forgeot d'Arc632fad32008-02-16 20:55:24 +00004092
Vinay Sajipb7edfc42008-04-02 21:10:23 +00004093- Issue #2115: Important speedup in setting __slot__ attributes. Also
Georg Brandl3ee81df2008-05-17 18:14:43 +00004094 prevent a possible crash: an Abstract Base Class would try to access
4095 a slot on a registered virtual subclass.
Amaury Forgeot d'Arc60d6c7f2008-02-15 21:22:45 +00004096
Georg Brandl3ee81df2008-05-17 18:14:43 +00004097- Fixed repr() and str() of complex numbers with infinity or nan as
4098 real or imaginary part.
Christian Heimes2f0da532008-02-15 06:57:08 +00004099
Georg Brandl3ee81df2008-05-17 18:14:43 +00004100- Clear all free lists during a gc.collect() of the highest generation
4101 in order to allow pymalloc to free more arenas. Python may give back
4102 memory to the OS earlier.
Christian Heimes3b718a72008-02-14 12:47:33 +00004103
Georg Brandl3ee81df2008-05-17 18:14:43 +00004104- Issue #2045: Fix an infinite recursion triggered when printing a
4105 subclass of collections.defaultdict, if its default_factory is set
4106 to a bound method.
Amaury Forgeot d'Arcb01aa432008-02-08 00:56:02 +00004107
Christian Heimesf75dbef2008-02-08 00:11:31 +00004108- Fixed a minor memory leak in dictobject.c. The content of the free
4109 list was not freed on interpreter shutdown.
4110
Georg Brandl21e99f42010-03-07 15:23:59 +00004111- Limit free list of method and built-in function objects to 256
Georg Brandl3ee81df2008-05-17 18:14:43 +00004112 entries each.
Christian Heimes6075a822008-02-06 12:44:34 +00004113
Georg Brandl3ee81df2008-05-17 18:14:43 +00004114- Patch #1953: Added ``sys._compact_freelists()`` and the C API
4115 functions ``PyInt_CompactFreeList`` and ``PyFloat_CompactFreeList``
Christian Heimes422051a2008-02-04 18:00:12 +00004116 to compact the internal free lists of pre-allocted ints and floats.
4117
Georg Brandl3ee81df2008-05-17 18:14:43 +00004118- Issue #1983: Fixed return type of fork(), fork1() and forkpty()
4119 calls. Python expected the return type int but the fork familie
4120 returns pi_t.
Christian Heimes951cc0f2008-01-31 23:08:23 +00004121
Georg Brandl3ee81df2008-05-17 18:14:43 +00004122- Issue #1678380: Fix a bug that identifies 0j and -0j when they
4123 appear in the same code unit.
Mark Dickinson105be772008-01-31 22:17:37 +00004124
Georg Brandl3ee81df2008-05-17 18:14:43 +00004125- Issue #2025: Add tuple.count() and tuple.index() methods to comply
4126 with the collections.Sequence API.
Raymond Hettinger5b07ebc2008-02-07 00:54:20 +00004127
Georg Brandl3ee81df2008-05-17 18:14:43 +00004128- Patch #1970 by Antoine Pitrou: Speedup unicode whitespace and
4129 linebreak detection
Christian Heimes4d4f2702008-01-30 11:32:37 +00004130
Georg Brandl3ee81df2008-05-17 18:14:43 +00004131- Added ``PyType_ClearCache()`` and ``sys._clear_type_cache`` to clear
4132 the internal lookup cache for ref leak tests.
Christian Heimes908caac2008-01-27 23:34:59 +00004133
Georg Brandl3ee81df2008-05-17 18:14:43 +00004134- Patch #1473257: generator objects gain a gi_code attribute. This is
4135 the same object as the func_code attribute of the function that
4136 produced the generator.
Georg Brandl0cdf9a32008-01-26 14:14:20 +00004137
Georg Brandl3ee81df2008-05-17 18:14:43 +00004138- Issue #1920: "while 0" statements were completely removed by the
4139 compiler, even in the presence of an "else" clause, which is
4140 supposed to be run when the condition is false. Now the compiler
4141 correctly emits bytecode for the "else" suite.
Amaury Forgeot d'Arc31eaafe2008-01-24 22:59:25 +00004142
Guido van Rossumeead05f2008-01-24 18:21:02 +00004143- A few crashers fixed: weakref_in_del.py (issue #1377858);
4144 loosing_dict_ref.py (issue #1303614, test67.py);
4145 borrowed_ref_[34].py (not in tracker).
4146
Vinay Sajipd7cf32e2008-01-24 12:43:33 +00004147- Issue #1069410: The "can't load dll" message box on Windows is
Christian Heimesb2302ba2008-01-23 17:15:06 +00004148 suppressed while an extension is loaded by calling SetErrorMode in
4149 dynload_win.c. The error is still reported properly.
4150
Georg Brandl3ee81df2008-05-17 18:14:43 +00004151- Issue #1915: Python compiles with --enable-unicode=no again. However
Christian Heimes082c9b02008-01-23 14:20:50 +00004152 several extension methods and modules do not work without unicode
4153 support.
4154
Georg Brandl26543b12008-01-21 18:36:51 +00004155- Issue #1882: when compiling code from a string, encoding cookies in the
4156 second line of code were not always recognized correctly.
4157
Georg Brandl14404b62008-01-19 19:27:05 +00004158- Issue #1679: "0x" was taken as a valid integer literal.
4159
Georg Brandl6caad7d2008-01-26 14:19:22 +00004160- Issue #1865: ``bytes`` as an alias for ``str`` and b"" as an alias "" were
Christian Heimes288e89a2008-01-18 18:24:07 +00004161 added.
4162
Christian Heimesc94e2b52008-01-14 04:13:37 +00004163- sys.float_info / PyFloat_GetInfo: The floating point information
4164 object was converted from a dict to a specialized structseq object.
4165
Georg Brandl3ee81df2008-05-17 18:14:43 +00004166- Patch #1816: Added sys.flags structseq. It exposes the status of
4167 most command line arguments and PYTHON* environment variables.
Christian Heimesf31b69f2008-01-14 03:42:48 +00004168
Georg Brandl3ee81df2008-05-17 18:14:43 +00004169- Objects/structseq.c: Implemented new structseq representation. The
4170 patch makes structseqs (e.g. the return value of os.stat) more
4171 readable.
Christian Heimes9c201962008-01-14 03:33:52 +00004172
Georg Brandl3ee81df2008-05-17 18:14:43 +00004173- Patch #1700288: added a type attribute cache that caches method
4174 accesses, resulting in speedups in heavily object-oriented code.
Amaury Forgeot d'Arce4c270c2008-01-14 00:29:41 +00004175
Neal Norwitz3fc15b82008-01-10 05:42:58 +00004176- Bug #1776: __import__() no longer accepts filenames on any platform.
4177 The first parameter to __import__() must be a valid module name.
Christian Heimes3403f152008-01-09 19:56:33 +00004178
Georg Brandlaed6c662008-01-07 17:25:53 +00004179- Patch #1668: renamed THREADDEBUG envvar to PYTHONTHREADDEBUG.
4180
Georg Brandl3ee81df2008-05-17 18:14:43 +00004181- Patch #602345: Add -B command line option, PYTHONDONTWRITEBYTECODE
4182 envvar and sys.dont_write_bytecode attribute. All these can be set
4183 to forbid Python to attempt to write compiled bytecode files.
Georg Brandl2da0fce2008-01-07 17:09:35 +00004184
Georg Brandl3ee81df2008-05-17 18:14:43 +00004185- Improve some exception messages when Windows fails to load an
4186 extension module. Now we get for example '%1 is not a valid Win32
4187 application' instead of 'error code 193'.
Amaury Forgeot d'Arce0b76952008-01-04 02:04:15 +00004188
Georg Brandl3ee81df2008-05-17 18:14:43 +00004189- Bug #1481296: Fixed long(float('nan')) != 0L.

Georg Brandl3ee81df2008-05-17 18:14:43 +00004191- Issue #1640: Added math.isinf(x), math.isnan(x) and math.copysign(x,
4192 y) functions.
Christian Heimese2ca4242008-01-03 20:23:15 +00004193
Christian Heimes0a8143f2007-12-18 23:22:54 +00004194- Issue #1635: Platform independent creation and representation of NaN
Georg Brandl3ee81df2008-05-17 18:14:43 +00004195 and INF. float("nan"), float("inf") and float("-inf") now work on
4196 every platform with IEEE 754 semantics.
Christian Heimes0a8143f2007-12-18 23:22:54 +00004197
Georg Brandl3ee81df2008-05-17 18:14:43 +00004198- Compiler now generates simpler and faster code for dictionary
4199 literals. The oparg for BUILD_MAP now indicates an estimated
4200 dictionary size. There is a new opcode, STORE_MAP, for adding
4201 entries to the dictionary.

4213
Nick Coghlanef01d822007-12-03 12:55:17 +00004214- PEP 366: Allow explicit relative imports when executing modules
4215 inside packages with the -m switch via a new module level
4216 __package__ attribute.
4217
Georg Brandl3ee81df2008-05-17 18:14:43 +00004218- Issue #1402: Fix a crash on exit, when another thread is still
4219 running, and if the deallocation of its frames somehow calls the
4220 PyGILState_Ensure() / PyGILState_Release() functions.
Amaury Forgeot d'Arcbe49a902007-11-30 20:37:22 +00004221

Georg Brandl3ee81df2008-05-17 18:14:43 +00004235- Issue #1265: Fix a problem with sys.settrace, if the tracing
4236 function uses a generator expression when at the same time the
4237 executed code is closing a paused generator.
Amaury Forgeot d'Arc0d75f092007-11-13 21:54:28 +00004238
Raymond Hettinger1760c8a2007-11-08 02:52:43 +00004239- sets and frozensets now have an isdisjoint() method.
4240
Raymond Hettinger3f8caa32007-10-24 01:28:33 +00004241- optimize the performance of builtin.sum().

Neal Norwitz44f326e2007-10-05 05:29:17 +00004243- Fix warnings found by the new version of the Coverity checker.
4244
Georg Brandl21e99f42010-03-07 15:23:59 +00004245- The enumerate() built-in function is no longer bounded to sequences
Georg Brandl3ee81df2008-05-17 18:14:43 +00004246 smaller than LONG_MAX. Formerly, it raised an OverflowError. Now,
4247 automatically shifts from ints to longs.
Raymond Hettinger8f669372007-10-03 21:18:11 +00004248
Georg Brandl3ee81df2008-05-17 18:14:43 +00004249- Issue #1686386: Tuple's tp_repr did not take into account the
4250 possibility of having a self-referential tuple, which is possible
4251 from C code. Nor did object's tp_str consider that a type's tp_str
4252 could do something that could lead to an inifinite recursion.
4253 Py_ReprEnter() and Py_EnterRecursiveCall(), respectively, fixed the
4254 issues.
Brett Cannon0b14f242007-09-30 19:45:10 +00004255
Georg Brandl3ee81df2008-05-17 18:14:43 +00004256- Issue #1164: It was possible to trigger deadlock when using the
4257 'print' statement to write to a file since the GIL was not released
4258 as needed. Now PyObject_Print() does the right thing along with
4259 various tp_print implementations of the built-in types and those in
4260 the collections module.
Brett Cannon01531592007-09-17 03:28:34 +00004261
Georg Brandl3ee81df2008-05-17 18:14:43 +00004262- Issue #1147: Exceptions were directly allowing string exceptions in

Brett Cannon1e534b52007-09-07 04:18:30 +00004269- Issue #1202533: Fix infinite recursion calls triggered by calls to
Georg Brandl3ee81df2008-05-17 18:14:43 +00004270 PyObject_Call() never calling back out to Python code to trigger
4271 recursion depth updates/checks. Required the creation of a static
4272 RuntimeError instance in case normalizing an exception put the
4273 recursion check value past its limit. Fixes crashers
4274 infinite_rec_(1|2|4|5).py.
Brett Cannon1e534b52007-09-07 04:18:30 +00004275
Georg Brandl3ee81df2008-05-17 18:14:43 +00004276- Patch #1031213: Decode source line in SyntaxErrors back to its

4280 with %G.
4281
Georg Brandl3ee81df2008-05-17 18:14:43 +00004282- Prevent expandtabs() on string and unicode objects from causing a
4283 segfault when a large width is passed on 32-bit platforms.

Neal Norwitz0ac60192007-05-27 04:08:54 +00004289- Add new attribute names for function objects. All the func_* become
Georg Brandl3ee81df2008-05-17 18:14:43 +00004290 __*__ attributes. (Some already existed, e.g., __doc__ and
4291 __name__.)
Neal Norwitz0ac60192007-05-27 04:08:54 +00004292
Neal Norwitz8b2bfbc2007-05-23 06:35:32 +00004293- Add -3 option to the interpreter to warn about features that are
4294 deprecated and will be changed/removed in Python 3.0.
4295
Georg Brandl2134e752007-05-21 20:34:16 +00004296- Patch #1686487: you can now pass any mapping after '**' in function
4297 calls.
4298
Collin Winter62903052007-05-18 23:11:24 +00004299- except clauses may now be spelled either "except E, target:" or
Georg Brandl3ee81df2008-05-17 18:14:43 +00004300 "except E as target:". This is to provide forwards compatibility
4301 with Python 3.0.
Collin Winter62903052007-05-18 23:11:24 +00004302
Brett Cannon229cee22007-05-05 01:34:02 +00004303- Deprecate BaseException.message as per PEP 352.
4304
Georg Brandl3ee81df2008-05-17 18:14:43 +00004305- Issue #1303614: don't expose object's __dict__ when the dict is
Georg Brandl21e99f42010-03-07 15:23:59 +00004306 inherited from a built-in base.
Armin Rigo9790a272007-05-02 19:23:31 +00004307
Vinay Sajip8549ce32007-05-06 17:53:37 +00004308- When __slots__ are set to a unicode string, make it work the same as
Neal Norwitzcbd9ee62007-04-14 05:25:50 +00004309 setting a plain string, ie don't expand to single letter identifiers.
4310
Raymond Hettinger13936692007-04-11 18:40:58 +00004311- Request #1191699: Slices can now be pickled.
4312
Raymond Hettinger4db5fe92007-04-12 04:10:00 +00004313- Request #1193128: str.translate() now allows a None argument for
4314 translations that only remove characters without re-mapping the
4315 remaining characters.
4316
Georg Brandl5cb76c12007-03-21 09:00:39 +00004317- Patch #1682205: a TypeError while unpacking an iterable is no longer
4318 masked by a generic one with the message "unpack non-sequence".
4319
Neal Norwitzaa754b72007-03-21 06:39:48 +00004320- Remove unused file Python/fmod.c.
4321
Guido van Rossum143b5642007-03-23 04:58:42 +00004322- Bug #1683368: The object.__init__() and object.__new__() methods are
4323 now stricter in rejecting excess arguments. The only time when
4324 either allows excess arguments is when it is not overridden and the
4325 other one is. For backwards compatibility, when both are
4326 overridden, it is a deprecation warning (for now; maybe a Py3k
Guido van Rossum234b1ff2007-03-23 19:39:01 +00004327 warning later). Also, type.__init__() insists on the same signature
4328 as supported by type.__new__().
Guido van Rossum143b5642007-03-23 04:58:42 +00004329
Georg Brandl3ee81df2008-05-17 18:14:43 +00004330- Patch #1675423: PyComplex_AsCComplex() now tries to convert an
4331 object to complex using its __complex__() method before falling back
4332 to the __float__() method. Therefore, the functions in the cmath
4333 module now can operate on objects that define a __complex__()
4334 method.
Georg Brandl2b869942007-03-17 16:08:45 +00004335
Georg Brandl3ee81df2008-05-17 18:14:43 +00004336- Patch #1623563: allow __class__ assignment for classes with
4337 __slots__. The old and the new class are still required to have the
4338 same slot names.
Žiga Seilnacht6f2d09c2007-03-16 11:59:38 +00004339
Georg Brandl3ee81df2008-05-17 18:14:43 +00004340- Patch #1642547: Fix an error/crash when encountering syntax errors

4344 ``object.__reduce_ex__()`` is called with an object that is faking
4345 its type.
Žiga Seilnacht20f43d32007-03-15 11:44:55 +00004346
Georg Brandl3ee81df2008-05-17 18:14:43 +00004347- Patch #1680015: Don't modify __slots__ tuple if it contains an
4348 unicode name.

Georg Brandl5240d742007-03-13 20:46:32 +00004350- Patch #1444529: the builtin compile() now accepts keyword arguments.
4351
Georg Brandl7b9c5552007-03-12 14:30:05 +00004352- Bug #1678647: write a newline after printing an exception in any
4353 case, even when converting the value to a string failed.
4354
Georg Brandl871f1bc2007-03-12 13:17:36 +00004355- The dir() function has been extended to call the __dir__() method on
Georg Brandl3ee81df2008-05-17 18:14:43 +00004356 its argument, if it exists. If not, it will work like before. This
4357 allows customizing the output of dir() in the presence of a
4358 __getattr__().
Georg Brandl871f1bc2007-03-12 13:17:36 +00004359
Collin Winter276887b2007-03-12 16:11:39 +00004360- Patch #922167: Python no longer segfaults when faced with infinitely
4361 self-recursive reload() calls (as reported by bug #742342).
4362

4367 parthensized forms. This means complex(repr(x)) now works instead of
4368 raising a ValueError.
Collin Wintere38051d2007-03-09 20:33:07 +00004369
Georg Brandlaa2321b2007-03-07 00:40:28 +00004370- Patch #703779: unset __file__ in __main__ after running a file. This
Georg Brandl3ee81df2008-05-17 18:14:43 +00004371 makes the filenames the warning module prints much more sensible
4372 when a PYTHONSTARTUP file is used.
Georg Brandlaa2321b2007-03-07 00:40:28 +00004373
Georg Brandl49aafc92007-03-07 00:34:46 +00004374- Variant of patch #697613: don't exit the interpreter on a SystemExit
4375 exception if the -i command line option or PYTHONINSPECT environment
Georg Brandl3ee81df2008-05-17 18:14:43 +00004376 variable is given, but break into the interactive interpreter just
4377 like on other exceptions or normal program exit.

4383 condition.
Georg Brandl098cd692007-03-06 12:17:50 +00004384
Georg Brandl0fca97a2007-03-05 22:28:08 +00004385- Patch #1674228: when assigning a slice (old-style), check for the
4386 sq_ass_slice instead of the sq_slice slot.
4387
Georg Brandl3ee81df2008-05-17 18:14:43 +00004388- When printing an unraisable error, don't print exceptions. before
4389 the name. This duplicates the behavior whening normally printing
4390 exceptions.
Neal Norwitz88516a62007-02-26 22:41:45 +00004391
Georg Brandl3ee81df2008-05-17 18:14:43 +00004392- Bug #1653736: Properly discard third argument to

Georg Brandl3ee81df2008-05-17 18:14:43 +00004398- Bug #1377858: Fix the segfaulting of the interpreter when an object
4399 created a weakref on itself during a __del__ call for new-style
4400 classes (classic classes still have the bug).
Brett Cannonf5bee302007-01-23 23:21:22 +00004401

4999 Python would crash instead of raising an error.
5000

5013
Georg Brandl3ee81df2008-05-17 18:14:43 +00005014- unittest now verifies more of its assumptions. In particular,

5016 accepted in TestSuite.addTest(). This should cause no
5017 incompatibility since it never made sense with ordinary subclasses
5018 -- the failure just occurred later, with a more cumbersome
5019 exception.

Georg Brandl3ee81df2008-05-17 18:14:43 +00005300- Issue #829951: In the smtplib module, SMTP.starttls() now complies
5301 with RFC 3207 and forgets any knowledge obtained from the server not
5302 obtained from the TLS negotiation itself. Patch contributed by Bill
5303 Fenner.
Gregory P. Smith2b3ba582008-01-17 08:03:17 +00005304
Georg Brandl3ee81df2008-05-17 18:14:43 +00005305- Issue #1339: The smtplib.SMTP class has been refactored a bit such
Gregory P. Smithbde4ae42008-01-17 08:35:49 +00005306 that the SMTP.starttls() caller no longer needs to call ehlo()
5307 beforehand. SMTP.starttls() now raises an exception of the server
Georg Brandl3ee81df2008-05-17 18:14:43 +00005308 does not claim to support starttls. Adds the
5309 SMTP.ehlo_or_helo_if_needed() method. Patch contributed by Bill

5390 complex, tuple, list, dict, set, and frozenset. Formerly, it would
5391 silently miscode subclasses of those types. Now, it raises a

Georg Brandl3ee81df2008-05-17 18:14:43 +00005408 time so that opening a database previously created with the DB_DUP
5409 or DB_DUPSORT flag set will keep the proper behavior on subsequent
5410 opens. Specifically: dictionary assignment to a DB object will
5411 replace all values for a given key when the database allows
5412 duplicate values. DB users should use DB.put(k, v) when they want
5413 to store duplicates; not DB[k] = v.
Gregory P. Smithec10a4a2007-11-05 02:32:26 +00005414

5420 characters with ASCII value less than 32. Also, it correctly quotes
5421 dots only if they occur on a single line, as opposed to the previous
5422 behavior of quoting dots if they are the second character of any
5423 line.
Georg Brandl4aef7272007-03-13 22:49:43 +00005424

5746-----
5747
Georg Brandl3ee81df2008-05-17 18:14:43 +00005748- Unified naming convention for free lists and their limits. All free
5749 lists in Object/ are named ``free_list``, the counter ``numfree``
5750 and the upper limit is a macro ``PyName_MAXFREELIST`` inside an
5751 #ifndef block.
Christian Heimes5b970ad2008-02-06 13:33:44 +00005752
Georg Brandl3ee81df2008-05-17 18:14:43 +00005753- ``PySet_Add()`` can now modify a newly created frozenset. Similarly
5754 to ``PyTuple_SetItem``, it can be used to populate a brand new
5755 frozenset; but it does not steal a reference to the added item.
Amaury Forgeot d'Arccab3d982008-02-03 22:51:43 +00005756
Vinay Sajipb7edfc42008-04-02 21:10:23 +00005757- Added ``PySet_Check()`` and ``PyFrozenSet_Check()`` to the set API.

Georg Brandl3ee81df2008-05-17 18:14:43 +00005759- Backport of PyUnicode_FromString(), _FromStringAndSize(), _Format
5760 and _FormatV from Python 3.0. Made PyLong_AsSsize_t and
5761 PyLong_FromSsize_t public functions.
Georg Brandl6caad7d2008-01-26 14:19:22 +00005762
5763- Patch #1720595: add T_BOOL to the range of structmember types.
5764
5765- Issue #1534: Added ``PyFloat_GetMax()``, ``PyFloat_GetMin()`` and
5766 ``PyFloat_GetInfo()`` to the float API.
5767
Georg Brandl3ee81df2008-05-17 18:14:43 +00005768- Issue #1521: On 64bit platforms, using PyArgs_ParseTuple with the t#
5769 of w# format code incorrectly truncated the length to an int, even
5770 when PY_SSIZE_T_CLEAN is set. The str.decode method used to return
5771 incorrect results with huge strings.
Georg Brandl6caad7d2008-01-26 14:19:22 +00005772
Georg Brandl3ee81df2008-05-17 18:14:43 +00005773- Issue #1629: Renamed Py_Size, Py_Type and Py_Refcnt to Py_SIZE,
5774 Py_TYPE and Py_REFCNT.

Georg Brandl3ee81df2008-05-17 18:14:43 +00005776- PEP 3123: Provide forward compatibility with Python 3.0, while
5777 keeping backwards compatibility. Add Py_Refcnt, Py_Type, Py_Size,
5778 and PyVarObject_HEAD_INIT.
Georg Brandl6caad7d2008-01-26 14:19:22 +00005779
Georg Brandl3ee81df2008-05-17 18:14:43 +00005780- Py_ssize_t fields work in structmember when HAVE_LONG_LONG is not
5781 defined.
Georg Brandl6caad7d2008-01-26 14:19:22 +00005782
5783- Patch #1733960: Allow T_LONGLONG to accept ints.
5784
5785- T_PYSSIZET can now be used in PyMemberDef lists for Py_ssize_t members.
5786

5791- Fix some leftovers from the conversion from int to Py_ssize_t
5792 (relevant to strings and sequences of more than 2**31 items).
5793
5794- Make _PyGILState_NoteThreadState() static, it was not used anywhere
5795 outside of pystate.c and should not be necessary.
5796
Georg Brandl3ee81df2008-05-17 18:14:43 +00005797- ``PyImport_Import`` and ``PyImport_ImportModule`` now always do
5798 absolute imports. In earlier versions they might have used relative
5799 imports under some conditions.
Christian Heimes000a0742008-01-03 22:16:32 +00005800
Georg Brandl3ee81df2008-05-17 18:14:43 +00005801- Added case insensitive comparison methods ``PyOS_stricmp(char*,
5802 char*)`` and ``PyOS_strnicmp(char*, char*, Py_ssize_t)``.
Christian Heimes000a0742008-01-03 22:16:32 +00005803
Georg Brandl3ee81df2008-05-17 18:14:43 +00005804- Bug #1542693: remove semi-colon at end of PyImport_ImportModuleEx

Georg Brandl3ee81df2008-05-17 18:14:43 +00005811- Patch #1706: Drop support for Win9x, WinME and NT4. Python now
5812 requires Windows 2000 or greater. The _WINVER and NTDDI_VERSION
5813 macros are set to Win2k for x86/32bit builds and WinXP for AMD64
5814 builds.
Christian Heimes95d64472008-02-09 19:55:22 +00005815
Georg Brandl3ee81df2008-05-17 18:14:43 +00005816- Conditionalize definition of _CRT_SECURE_NO_DEPRECATE and

Georg Brandl3ee81df2008-05-17 18:14:43 +00005829- Removed the macfs module. It had been deprecated since Python 2.5.
5830 This lead to the deprecation of macostools.touched() as it relied
5831 solely on macfs and was a no-op under OS X.
