45
Antoine Pitroufc69af12010-04-24 20:04:58 +000046- Issue #5103: SSL handshake would ignore the socket timeout and block

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

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

132Core and Builtins
133-----------------
134
Philip Jenveyaebbaeb2010-04-06 23:24:45 +0000135- Issue #7301: Add environment variable $PYTHONWARNINGS.
136
Benjamin Peterson3a1dfa22010-04-06 21:50:00 +0000137- Issue #8329: Don't return the same lists from select.select when no fds are
138 changed.
139
Mark Dickinson82791672010-04-06 16:47:55 +0000140- Issue #8259: 1L << (2**31) no longer produces an 'outrageous shift error'
141 on 64-bit machines. The shift count for either left or right shift is
142 permitted to be up to sys.maxsize.
143
Benjamin Peterson4ceeeb02010-04-03 22:48:51 +0000144- Ensure that tokenization of identifiers is not affected by locale.

149
Eric Smithd44b2fc2010-04-02 12:30:56 +0000150- Issue #7994: Issue a PendingDeprecationWarning if object.__format__
151 is called with a non-empty format string. This is an effort to
152 future-proof user code. If a derived class does not currently
153 implement __format__ but later adds its own __format__, it would
154 most likely break user code that had supplied a format string. This
155 will be changed to a DeprecationWaring in Python 3.3 and it will be
156 an error in Python 3.4.
157
Antoine Pitroua57df2c2010-03-31 21:32:15 +0000158- Issue #8268: Old-style classes (not just instances) now support weak
159 references.

Georg Brandlba83f822010-03-14 09:50:54 +0000172 (SIGINT). If an error occurs while importing the site module, the error is
173 printed and Python exits. Initialize the GIL before importing the site
Victor Stinner66644262010-03-10 22:30:19 +0000174 module.
175

184 using the new attributes `ssl.OPENSSL_VERSION`, `ssl.OPENSSL_VERSION_INFO`
185 and `ssl.OPENSSL_VERSION_NUMBER`.
186
Benjamin Peterson76a23c12010-04-04 23:23:22 +0000187- Issue #8310: Allow dis to examine new style classes.
188
Mark Dickinson8a950712010-04-03 15:47:46 +0000189- Issue #8257: The Decimal construct now accepts a float instance
190 directly, converting that float to a Decimal of equal value:

196
Raymond Hettingera551f312010-04-04 18:34:45 +0000197- the functools module now has a total_ordering() class decorator
Georg Brandl4fabac52010-04-14 08:53:38 +0000198 to simplify the specification of rich comparisons.
Raymond Hettingera551f312010-04-04 18:34:45 +0000199
Raymond Hettingerbb006cf2010-04-04 21:45:01 +0000200- The functools module also adds cmp_to_key() as a tool to transition
Raymond Hettingera551f312010-04-04 18:34:45 +0000201 old-style comparison functions to new-style key-functions.
202
Mark Dickinson7c63eee2010-04-02 22:27:36 +0000203- Issue #8294: The Fraction constructor now accepts Decimal and float
204 instances directly.
205
Mark Dickinsone096e822010-04-02 10:17:07 +0000206- Issue #7279: Comparisons involving a Decimal signaling NaN now
207 signal InvalidOperation instead of returning False. (Comparisons
Mark Dickinsonf3eeca12010-04-02 10:35:12 +0000208 involving a quiet NaN are unchanged.) Also, Decimal quiet NaNs
209 are now hashable; Decimal signaling NaNs remain unhashable.
Mark Dickinsone096e822010-04-02 10:17:07 +0000210
Mark Dickinson99d80962010-04-02 08:53:22 +0000211- Issue #2531: Comparison operations between floats and Decimal

217 argument `-` which tells it to read files to compile from stdin. Each line
218 is read on demand and the named file is compiled immediately. (Original
219 patch by Piotr Ożarowski).
220
221- Issue #3135: Add inspect.getcallargs, which binds arguments to a function
222 like a normal call.
Benjamin Peterson7e213252010-03-30 17:58:13 +0000223
Florent Xicluna58b65662010-03-30 16:29:03 +0000224- Backwards incompatible change: Unicode codepoints line tabulation (0x0B) and
225 form feed (0x0C) are now considered linebreaks, as specified in Unicode
226 Standard Annex #14. See issue #7643.

230 a Fractions instance now raise TypeError instead of returning
231 True/False. This makes Fraction <=> complex comparisons consistent with
232 int <=> complex, float <=> complex, and complex <=> complex comparisons.
233

Georg Brandlba83f822010-03-14 09:50:54 +0000300- Issue #7143: email: ``get_payload()`` used to strip any trailing newline from
301 a base64 transfer-encoded payload *after* decoding it; it no longer does.
302 This is a behavior change, so email's minor version number is now bumped, to
303 version 4.0.2, for the 2.7 release.

Mark Dickinson4846a8e2010-04-03 14:05:10 +0000329- Issue #8300: When passing a non-integer argument to struct.pack with any
330 integer format code, struct.pack first attempts to convert the non-integer
331 using its __index__ method. If that method is non-existent or raises
332 TypeError it goes on to try the __int__ method, as described below.
333
Georg Brandlba83f822010-03-14 09:50:54 +0000334- Issue #1530559: When passing a non-integer argument to struct.pack with *any*
335 integer format code (one of 'bBhHiIlLqQ'), struct.pack attempts to use the
336 argument's __int__ method to convert to an integer before packing. It also
337 produces a DeprecationWarning in this case. (In Python 2.6, the behaviour
338 was inconsistent: __int__ was used for some integer codes but not for others,
339 and the set of integer codes for which it was used differed between native
340 packing and standard packing.)

Georg Brandlba83f822010-03-14 09:50:54 +0000545- Issue #7712: test_support gained a new ``temp_cwd`` context manager which is
546 now also used by regrtest to run all the tests in a temporary directory. The
547 original CWD is saved in ``test.test_support.SAVEDCWD``. Thanks to Florent
548 Xicluna who helped with the patch.

565 and read operations on write-only file objects. On Windows, the system C
Georg Brandlba83f822010-03-14 09:50:54 +0000566 library would return a bogus result; on Solaris, it was possible to crash the
567 interpreter. Patch by Stefan Krah.

Georg Brandlba83f822010-03-14 09:50:54 +0000580- Issue #7766: Change ``sys.getwindowsversion()`` return value to a named tuple
581 and add the additional members returned in an OSVERSIONINFOEX structure. The
582 new members are service_pack_major, service_pack_minor, suite_mask, and

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

620 XML processing instructions and comments. These raw characters are allowed
621 by the XML specification, and are necessary when outputting e.g. PHP code in

Antoine Pitroud840e512010-02-04 20:20:18 +0000630- Issue #4772: Raise a ValueError when an unknown Bluetooth protocol is
Georg Brandlba83f822010-03-14 09:50:54 +0000631 specified, rather than fall through to AF_PACKET (in the ``socket`` module).
Antoine Pitroud840e512010-02-04 20:20:18 +0000632 Also, raise ValueError rather than TypeError when an unknown TIPC address
633 type is specified. Patch by Brian Curtin.

Antoine Pitrouf3fa0742010-01-31 22:26:04 +0000637- Issue #6939: Fix file I/O objects in the `io` module to keep the original
Georg Brandlba83f822010-03-14 09:50:54 +0000638 file position when calling `truncate()`. It would previously change the file
639 position to the given argument, which goes against the tradition of
Antoine Pitrouf3fa0742010-01-31 22:26:04 +0000640 ftruncate() and other truncation APIs. Patch by Pascal Chambon.
641
Benjamin Petersone06f7112010-01-28 02:15:02 +0000642- UserDict is now a new-style class.

Georg Brandlba83f822010-03-14 09:50:54 +0000644- Issue #7610: Reworked implementation of the internal ``zipfile.ZipExtFile``
645 class used to represent files stored inside an archive. The new
646 implementation is significantly faster and can be wrapped in a
647 ``io.BufferedReader`` object for more speedups. It also solves an issue
648 where interleaved calls to ``read()`` and ``readline()`` give wrong results.
649 Patch by Nir Aides.

657 when the release file is empty.
Benjamin Petersona43f34c2010-01-25 03:31:13 +0000658
Georg Brandlba83f822010-03-14 09:50:54 +0000659- Issue #7748: Since unicode values are supported for some metadata options in
660 Distutils, the DistributionMetadata get_* methods will now return an utf-8
661 encoded string for them. This ensures that the upload and register commands
662 send the correct values to PyPI without any error.

738
Georg Brandlba83f822010-03-14 09:50:54 +0000739- The ``__complex__()`` method is now looked up on the class of instances to
740 make it consistent with other special methods.

Antoine Pitrou5b7139a2010-01-02 21:12:58 +0000742- Issue #7462: Implement the stringlib fast search algorithm for the `rfind`,
743 `rindex`, `rsplit` and `rpartition` methods. Patch by Florent Xicluna.
744
Mark Dickinson1b34d252010-01-01 17:27:30 +0000745- Issue #5080: A number of functions and methods previously produced a
Georg Brandlba83f822010-03-14 09:50:54 +0000746 DeprecationWarning when passed a float argument where an integer was expected.
747 These functions and methods now raise TypeError instead. The majority of the
748 effects of this change are in the extension modules, but some core functions
749 and methods are affected: notably the 'chr', 'range' and 'xrange' builtins,
750 and many unicode/str methods.

Georg Brandlba83f822010-03-14 09:50:54 +0000763- Issue #1811: Improve accuracy and cross-platform consistency for true division
764 of integers: the result of a/b is now correctly rounded for ints a and b (at
765 least on IEEE 754 platforms), and in particular does not depend on the
766 internal representation of a long.

774
Georg Brandlba83f822010-03-14 09:50:54 +0000775 These executables now work properly with the arch(1) command: ``arch -ppc
776 python`` will start a universal binary version of python in PPC mode (unlike
777 previous releases).

917 to 'g' for large values.
Amaury Forgeot d'Arcd7288712009-12-01 21:51:04 +0000918
Georg Brandlba83f822010-03-14 09:50:54 +0000919- Remove switch from "%f" formatting to "%g" formatting for floats larger than
920 1e50 in absolute value.
Mark Dickinson9dd5e162009-11-23 20:54:09 +0000921

931 10.6.
Ronald Oussoren315cd0c2009-11-19 16:25:21 +0000932
Georg Brandlba83f822010-03-14 09:50:54 +0000933- Issue #7117: ``repr(x)`` for a float x returns a result based on the shortest
934 decimal string that's guaranteed to round back to x under correct rounding
935 (with round-half-to-even rounding mode). Previously it gave a string based on
936 rounding x to 17 decimal digits. repr(x) for a complex number behaves
937 similarly. On platforms where the correctly-rounded strtod and dtoa code is
938 not supported (see below), repr is unchanged.
Mark Dickinsonb678de82009-11-19 18:41:49 +0000939
Georg Brandlba83f822010-03-14 09:50:54 +0000940- Issue #7117: On almost all platforms: float-to-string and string-to-float
941 conversions within Python are now correctly rounded. Places these conversions
942 occur include: str for floats and complex numbers; the float and complex
943 constructors; old-style and new-style numeric formatting; serialization and
944 deserialization of floats and complex numbers using marshal, pickle and json;
945 parsing of float and imaginary literals in Python code; Decimal-to-float
946 conversion.
Mark Dickinsonb678de82009-11-19 18:41:49 +0000947
Georg Brandlba83f822010-03-14 09:50:54 +0000948 The conversions use a Python-adapted version of David Gay's well-known dtoa.c,
949 providing correctly-rounded strtod and dtoa C functions. This code is
950 supported on Windows, and on Unix-like platforms using gcc, icc or suncc as
951 the C compiler. There may be a small number of platforms on which correct
952 operation of this code cannot be guaranteed, so the code is not used: notably,
953 this applies to platforms where the C double format is not IEEE 754 binary64,
954 and to platforms on x86 hardware where the x87 FPU is set to 64-bit precision
955 and Python's configure script is unable to determine how to change the FPU
956 precision. On these platforms conversions use the platform strtod and dtoa,
957 as before.

Georg Brandlba83f822010-03-14 09:50:54 +0000959- Issue #7117: Backport round implementation from Python 3.x. ``round()`` now
960 uses the correctly-rounded string <-> float conversions described above (when
961 available), and so produces correctly rounded results that will display nicely
962 under the float repr. There are two related small changes: (1) round now
963 accepts any class with an ``__index__()`` method for its second argument (but
964 no longer accepts floats for the second argument), and (2) an excessively
965 large second integer argument (e.g., ``round(1.234, 10**100)``) no longer
966 raises an exception.

Georg Brandlba83f822010-03-14 09:50:54 +00001113- Issue #5920: For ``float.__format__()``, change the behavior with the empty
1114 presentation type (that is, not one of 'e', 'f', 'g', or 'n') to be like 'g'
1115 but with at least one decimal point and with a default precision
1116 of 12. Previously, the behavior the same but with a default precision of 6.
1117 This more closely matches ``str()``, and reduces surprises when adding
1118 alignment flags to the empty presentation type. This also affects the new
1119 complex.__format__ in the same way.

1303 ``offsetof(PyStringObject, ob_sval) + 1`` when allocating memory for str
1304 instances. On a typical machine this saves 3 bytes of memory (on average) per

1310
Georg Brandlba83f822010-03-14 09:50:54 +00001311- Issue #3689: The list reversed iterator now supports __length_hint__ instead

1316
Georg Brandlba83f822010-03-14 09:50:54 +00001317- Issue #4233: Changed semantic of ``_fileio.FileIO``'s ``close()`` method on
1318 file objects with closefd=False. The file descriptor is still kept open but
1319 the file object behaves like a closed file. The ``FileIO`` object also got a
1320 new readonly attribute ``closefd``.

1339
Benjamin Peterson399b1fe2008-10-25 02:53:28 +00001340- Using ``nonlocal`` as a variable name will now raise a Py3k SyntaxWarning
Georg Brandl7fb00ad2008-10-25 07:00:52 +00001341 because it is a reserved word in 3.x.

Georg Brandlba83f822010-03-14 09:50:54 +00001343- On windows, ``os.chdir()`` given unicode was not working if
1344 GetCurrentDirectoryW returned a path longer than MAX_PATH. (But It's doubtful
1345 this code path is really executed because I cannot move to such directory on
1346 win2k)

Georg Brandlba83f822010-03-14 09:50:54 +00001348- Issue #4069: When ``set.remove(element)`` is used with a set element, the
1349 element is temporarily replaced with an equivalent frozenset. But the
1350 eventual KeyError would always report the empty ``frozenset()`` as the missing
1351 key. Now it correctly refers to the initial element.

1370
Walter Dörwalded960ac2009-05-03 22:36:33 +00001371- Issue #5108: Handle %s like %S and %R in PyUnicode_FromFormatV(): Call
1372 PyUnicode_DecodeUTF8() once, remember the result and output it in a second
1373 step. This avoids problems with counting UTF-8 bytes that ignores the effect
1374 of using the replace error handler in PyUnicode_DecodeUTF8().
1375
Walter Dörwald726ba8e2009-05-06 14:32:35 +00001376- Issue #3739: The unicode-internal encoder now reports the number of characters
1377 consumed like any other encoder (instead of the number of bytes).
1378
Georg Brandlba83f822010-03-14 09:50:54 +00001379- Issue #2422: When compiled with the ``--with-valgrind`` option, the pymalloc
1380 allocator will be automatically disabled when running under Valgrind. This
1381 gives improved memory leak detection when running under Valgrind, while taking
1382 advantage of pymalloc at other times.

2550 neither __int__ nor __long__, TypeError used to be raised (with a

Antoine Pitrou4698d992009-05-31 14:20:14 +00002629- Issue #6152: New option '-j'/'--multiprocess' for regrtest allows running
2630 regression tests in parallel, shortening the total runtime.

Georg Brandlba83f822010-03-14 09:50:54 +00002632- Issue #5354: New test support function import_fresh_module() makes it easy to
2633 import both normal and optimised versions of modules. test_heapq and
2634 test_warnings have been adjusted to use it, tests for other modules with both
2635 C and Python implementations in the stdlib can be adjusted to use it over
2636 time.

Georg Brandlba83f822010-03-14 09:50:54 +00002644- regrtest no longer treats ImportError as equivalent to SkipTest. Imports that
2645 should cause a test to be skipped are now done using import_module from test
2646 support, which does the conversion.

2748
Amaury Forgeot d'Arc05e34492008-09-10 22:04:45 +00002749- Issue #3743: In a few places, PY_FORMAT_SIZE_T was incorrectly used with
2750 PyString_FromFormat or PyErr_Format to display size_t values. The macro
2751 PY_FORMAT_SIZE_T is designed to select the correct format for the OS
2752 ``printf`` function, whereas PyString_FromFormat has an independent
2753 implementation and uses "%zd" on all platforms for size_t values.
2754 This makes a difference on win64, where ``printf`` needs "%Id" to display
2755 64bit values.

Benjamin Peterson97179b02008-09-09 20:55:01 +00002757- Issue #3634: _weakref.ref(Exception).__init__() gave invalid return value on

Antoine Pitroud4ae97b2008-08-29 18:39:48 +00002772 was correctly parsed but parsing of subsequent arguments failed.
2773
Vinay Sajip35e3b032008-09-01 14:33:59 +00002774- Issue #2534: speed up isinstance() and issubclass() by 50-70%, so as to
Antoine Pitrou0668c622008-08-26 22:42:08 +00002775 match Python 2.5 speed despite the __instancecheck__ / __subclasscheck__
2776 mechanism. In the process, fix a bug where isinstance() and issubclass(),
2777 when given a tuple of classes as second argument, were looking up
2778 __instancecheck__ / __subclasscheck__ on the tuple rather than on each
2779 type object.

2923Core and Builtins
2924-----------------
2925
Guido van Rossumf8402962008-08-20 15:01:50 +00002926- Issue #1878: Remove Py_TPFLAGS_HAVE_VERSION_TAG from
2927 Py_TPFLAGS_DEFAULT when not building the core. This means 3rd party
2928 extensions do not automatically benefit from the class attribute
2929 cache; they will have to explicitly add Py_TPFLAGS_HAVE_VERSION_TAG
2930 to their tp_flags field if they care. This is a backwards
2931 compatibility feature; in 3.0, all types will use the cache by
2932 default.
2933
Benjamin Petersonf647dc12008-08-20 01:27:30 +00002934- Keyword arguments can now follow starred arguments. (``f(a, *args,
2935 keyword=23)`` is now valid syntax.)
2936
Thomas Heller0ad5ae02008-08-19 19:25:04 +00002937- ctypes function pointers that are COM methods have a boolean True
2938 value again.
2939
Martin v. Löwisf91d46a2008-08-12 14:49:50 +00002940- Issue #3139: Make buffer-interface thread-safe wrt. PyArg_ParseTuple,
2941 by denying s# to parse objects that have a releasebuffer procedure,
2942 and introducing s*.
2943
Georg Brandl1e13ea92008-08-11 09:07:59 +00002944- Issue #3537: Fix an assertion failure when an empty but presized dict
2945 object was stored in the freelist.
2946
Mark Dickinsonb6467572008-08-04 21:30:09 +00002947- Issue #1481296: Make long(float('nan')) and int(float('nan')) raise
2948 ValueError consistently across platforms.
2949
Amaury Forgeot d'Arc39fd6722008-07-31 21:28:03 +00002950- Issue #3479: On platforms where sizeof(int) is smaller than sizeof(long)
2951 (64bit Unix, for example), unichr() would truncate its argument and return
2952 u'\x00' for unichr(2**32). Now it properly raises an OverflowError.
2953
Neal Norwitze7d8be82008-07-31 17:17:14 +00002954- Apply security patches from Apple.
2955
Amaury Forgeot d'Arc246daed2008-07-31 00:42:16 +00002956- Issue #2542: Now that issubclass() may call arbitrary code, ensure that
2957 PyErr_ExceptionMatches returns 0 when an exception occurs there.
2958
Antoine Pitrou92f82162008-07-25 22:22:08 +00002959- Issue #1819: function calls with several named parameters are now on
2960 average 35% faster (as measured by pybench).
2961
Amaury Forgeot d'Arce4921fe2008-07-21 22:00:38 +00002962- Issue #2378: An unexpected UnboundLocalError or NameError could appear when
2963 the python debugger steps into a class statement: the free variables (local
2964 variables defined in an outer scope) would be deleted from the outer scope.
2965
Gregory P. Smith0470bab2008-07-22 04:46:32 +00002966- Issue #2620: Overflow checking when allocating or reallocating memory
2967 was not always being done properly in some python types and extension
2968 modules. PyMem_MALLOC, PyMem_REALLOC, PyMem_NEW and PyMem_RESIZE have
2969 all been updated to perform better checks and places in the code that
2970 would previously leak memory on the error path when such an allocation
2971 failed have been fixed.

2974-------
2975
Hirokazu Yamamoto838c79f2008-08-20 13:14:07 +00002976- Issue #3612: Added some missing basic types in ctypes.wintypes.
2977
Benjamin Petersone977ad42008-08-20 01:42:01 +00002978- The methods ``is_in_tuple()``, ``is_vararg()``, and ``is_keywordarg()`` of
2979 symtable.Symbol have been deprecated for removal in 3.0 and the next release.
2980
Amaury Forgeot d'Arc351ffb82008-08-18 19:23:47 +00002981- Issue #2234: distutils failed for some versions of the cygwin compiler. The
2982 version reported by these tools does not necessarily follow the python
2983 version numbering scheme, so the module is less strict when parsing it.
2984
Nick Coghlanf70385a2008-08-18 12:42:46 +00002985- Issue #2235: Added Py3k warnings for types which will become unhashable
2986 under the stricter __hash__ inheritance rules in 3.0. Several types
2987 which did not meet the rules for hash invariants and were already
2988 unhashable in 3.0 have now been explicitly flagged as unhashable in
2989 2.6 as well (collections.Mapping, collections.Set, unittest.TestSuite,
2990 xml.dom.minidom.NamedNodeMap, numbers.Number, UserList.UserList)
2991
Brett Cannon88f801d2008-08-18 00:46:22 +00002992- Update __all__ for cookielib, csv, os, urllib2, and weakref to include things
2993 imported into the module but exposed as part of the module's API.
2994
Brett Cannon7b96f072008-08-18 00:41:11 +00002995- Remove an unneeded import of abc.ABCMeta from 'inspect'.
2996
Brett Cannon46225e72008-08-18 00:36:52 +00002997- Remove unneeded imports of 'sys' and 'warnings' from 'io'.
2998
Brett Cannon25c9d6a2008-08-17 22:10:11 +00002999- Remove unneeded imports of 'warnings' from shelve, filecmp, and dummy_thread.
3000
Hirokazu Yamamoto41a81eb2008-08-17 13:10:46 +00003001- Issue #3575: Incremental decoder's decode function now takes bytearray
3002 by using 's*' instead of 't#'.
3003
Mark Dickinson3e4caeb2009-02-21 20:27:01 +00003004- Issue #2222: Fixed reference leak when occurred os.rename()
Hirokazu Yamamoto7f30a682008-08-17 09:46:56 +00003005 fails unicode conversion on 2nd parameter. (windows only)
3006
Facundo Batista94f243a2008-08-17 03:38:39 +00003007- Issue 2464. urllib2 now supports a malformation in the URL received
3008 in a redirect.
3009
Brett Cannonabe423e2008-08-16 21:47:07 +00003010- Silence the DeprecationWarning raised when importing mimetools in
Brett Cannon721b1452008-08-16 22:00:27 +00003011 BaseHTTPServer, cgi (and rfc822), httplib.
Brett Cannonabe423e2008-08-16 21:47:07 +00003012
Facundo Batistaeb90b782008-08-16 14:44:07 +00003013- Issue #2776: fixed small issue when handling an URL with double slash
3014 after a 302 response in the case of not going through a proxy.
3015
Antoine Pitroub90a8be2008-08-15 21:03:21 +00003016- Issue #2676: in the email package, content-type parsing was hanging on
3017 pathological input because of quadratic or exponential behaviour of a
3018 regular expression.
3019
Antoine Pitrou11ec65d2008-08-14 21:04:30 +00003020- Issue #3476: binary buffered reading through the new "io" library is now
3021 thread-safe.
3022
Brett Cannonbf3157b2008-08-14 05:00:03 +00003023- Silence the DeprecationWarning of rfc822 when it is imported by mimetools
3024 since mimetools itself is deprecated. Because modules are cached, all
3025 subsequent imports of rfc822 will not raise a visible DeprecationWarning.
3026
Antoine Pitrou9fcd4b32008-08-11 17:21:36 +00003027- Issue #3134: shutil referenced undefined WindowsError symbol.
3028
Robert Schuppenies14646332008-08-10 11:01:53 +00003029- Issue #1342811: Fix leak in Tkinter.Menu.delete. Commands associated to
3030 menu entries were not deleted.
3031
Brett Cannon83e81842008-08-09 23:30:55 +00003032- Copied the implementation of reduce() to _functools.reduce() to have a
3033 version that did not raise a DeprecationWarning under -3.
3034
Antoine Pitrou76b8bee2008-08-09 17:27:23 +00003035- Issue #3205: When iterating over a BZ2File fails allocating memory, raise
3036 a MemoryError rather than silently stop the iteration.
3037
Guido van Rossum59ce9012008-08-09 14:55:34 +00003038- Issue #3487: sre "bytecode" validator. Passing invalid "re-bytecode"
3039 to _sre.compile() will now be rejected. This should not affect anybody
3040 since the re.compile() function never generates invalid re-bytecode.
3041
Skip Montanaroa032bf42008-08-08 22:52:51 +00003042- Issue #3436: Make csv.DictReader's fieldnames attribute a property so that
3043 upon first access it can be automatically initialized from the csv file if
3044 it wasn't initialized during instantiation.
3045
Brett Cannon3aa2a492008-08-06 22:28:09 +00003046- Issue #2338: Create imp.reload() to help with transitioning to Python 3.0 as
3047 the reload() built-in has been removed.
3048
Brett Cannon7e30b672008-08-04 21:52:25 +00003049- Changed code in the following modules/packages to remove warnings raised
Brett Cannonc1b76e42008-08-09 23:06:16 +00003050 while running under the ``-3`` flag: aifc, asynchat, asyncore, bdb, bsddb,
Brett Cannon047e4a92008-08-17 04:16:04 +00003051 ConfigParser, cookielib, csv, difflib, distutils, DocXMLRPCServer, email,
3052 filecmp, fileinput, inspect, logging, modulefinder, pdb, pickle, profile,
3053 pstats, pydoc, re, rlcompleter, SimpleXMLRPCServer, shelve, socket,
3054 subprocess, sqlite3, tarfile, Tkinter, test.test_support, textwrap,
3055 threading, tokenize, traceback, urlparse, wsgiref, xml, xmlrpclib.
Brett Cannon7e30b672008-08-04 21:52:25 +00003056
Lars Gustäbel727bd0b2008-08-02 11:26:39 +00003057- Issue #3039: Fix tarfile.TarFileCompat.writestr() which always
3058 raised an AttributeError.
3059
Benjamin Peterson01a24322008-07-28 23:35:27 +00003060- Issue #2523: Fix quadratic behaviour when read()ing a binary file without
Antoine Pitroude781a42008-08-09 12:43:23 +00003061 asking for a specific length. This problem only affected files opened
3062 using the new "io" module, not the built-in open() function.
Benjamin Peterson01a24322008-07-28 23:35:27 +00003063
Mark Dickinsonfe84cce2008-07-27 06:39:07 +00003064- Issue #3449: Update decimal module to use most recent specification
3065 (v. 1.68) and tests (v. 2.58) from IBM.
3066
Skip Montanarof9ac43f2008-07-27 00:50:41 +00003067- Issue 3437: Bug fix in robotparser parsing of Allow: lines.
3068
Raymond Hettinger8c664e82008-07-25 18:43:33 +00003069- Issue 1592: Improve error reporting when operations are attempted
3070 on a closed shelf.

3073
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00003074- Issue #3120: On 64-bit Windows the subprocess module was truncating handles.
3075
3076- Issue #3303: Fix a crash in locale.strcoll() when calling it with
3077 invalid arguments.
3078
3079- Issue #3302: Fix several crashes when calling locale's gettext functions
3080 with None arguments.
3081
3082- Issue #3389: Allow resolving dotted names for handlers in logging
3083 configuration files.
3084
3085- Deprecate the sunaudio module for removal in Python 3.0.
3086
Antoine Pitrou5fdfa3e2008-07-25 19:42:26 +00003087- Issue #3394: zipfile.writestr sets external attributes when passed a
3088 file name rather than a ZipInfo instance, so files are extracted with
3089 mode 0600 rather than 000 under Unix.
3090
Gregory P. Smitha36f8fe2008-08-04 00:13:29 +00003091- Issue #1857: subprocess.Popen.poll gained an additional _deadstate keyword
3092 argument in python 2.5, this broke code that subclassed Popen to include its
3093 own poll method. Fixed my moving _deadstate to an _internal_poll method.

3102
Nick Coghlan6e8fef02008-08-18 13:14:22 +00003103- Issue #2235: the C API function PyObject_HashNotImplemented and its
3104 interaction with the tp_hash slot (added in 2.6b2) are now documented
3105
Nick Coghlan2a0c2b12008-08-04 12:47:17 +00003106- Issue #643841: The language reference now provides more detailed
3107 coverage of the lookup process for special methods. The disclaimers
3108 regarding lack of coverage of new-style classes have also been
3109 removed, since the coverage is now fairly reasonable.

3118-----------------
3119
Georg Brandl3e483f62008-07-16 22:57:41 +00003120- Issue #3156: Fix inconsistent behavior of the bytearray type: all
3121 its methods now allow for items objects that can be converted to
3122 an integer using operator.index().
3123
Mark Dickinson64b7e502008-07-16 09:40:03 +00003124- Issue #3360: Fix incorrect parsing of '020000000000.0', which
3125 produced a ValueError instead of giving the correct float.
3126
Eric Smitha5fa5a22008-07-16 00:11:49 +00003127- Issue #3083: Add alternate (#) formatting for bin, oct, hex output
3128 for str.format(). This adds the prefix 0b, 0o, or 0x, respectively.
3129
Mark Dickinson7103aa42008-07-15 19:08:33 +00003130- Issue #3008: the float type has a new instance method 'float.hex'
3131 and a new class method 'float.fromhex' to convert floating-point
3132 numbers to and from hexadecimal strings, respectively.
3133
Nick Coghlan6d6bd442008-07-15 15:40:22 +00003134- Issue #2235: __hash__ is once again inherited by default. To allow
3135 collections.Hashable to remain meaningful in the presence of the
3136 default hash implementation (object.__hash__), it is now possible
3137 to explicit block inheritance of hash by setting __hash__=None at
3138 the Python level, or tp_hash=PyObject_HashNotImplemented at the C
3139 level.
3140
Nick Coghlanb028f502008-07-13 14:52:36 +00003141- Issue #3221: Issue a RuntimeWarning instead of raising SystemError if
3142 the parent module cannot be found while performing an absolute import.
3143 This means that an incorrectly defined __package__ attribute will
3144 now only prevent relative imports in that module rather than causing
3145 all imports from that module to fail.
3146
Nick Coghlan14ff9942008-07-08 14:21:42 +00003147- Issue #2517: Allow unicode messages in Exceptions again by correctly
3148 bypassing the instance dictionary when looking up __unicode__ on
3149 new-style classes.
3150
Amaury Forgeot d'Arcbdd941f2008-07-01 20:38:04 +00003151- Issue #3242: Fix a crash inside the print statement, if sys.stdout is
3152 set to a custom object whose write() method happens to install
3153 another file in sys.stdout.
3154
Amaury Forgeot d'Arc1f40c8a2008-06-30 22:42:40 +00003155- Issue #3088: Corrected a race condition in classes derived from
3156 threading.local: the first member set by a thread could be saved in
3157 another thread's dictionary.
3158
Mark Dickinson1ec2fcd2008-06-20 14:53:43 +00003159- Issue #3004: Minor change to slice.indices(): the start and stop
3160 arguments are now treated identically, making the behaviour easier
3161 to describe and understand. For example, slice(None, -10,
3162 1).indices(9) now returns (0, 0, 1) instead of (0, -1, 1), and
3163 slice(None, 10, -1).indices(10) returns (9, 9, -1) instead of (9,
3164 10, -1).
3165
Georg Brandl278fc502008-07-19 12:46:12 +00003166- Issue #3219: Calling a function with repeated keyword arguments,
3167 f(a=2, a=23), would not cause a syntax error. This was a regression
3168 from 2.4 caused by the switch to the new compiler.
Benjamin Peterson175e4d92008-07-01 19:34:52 +00003169
Georg Brandl278fc502008-07-19 12:46:12 +00003170- Issue #2862: Make int and float freelist management consistent with
3171 other freelists. Changes their CompactFreeList apis into
3172 ClearFreeList apis and calls them via gc.collect().

Thomas Heller57adf222008-08-14 19:10:48 +00003177- Issue #3554: ctypes.string_at and ctypes.wstring_at did call Python
3178 api functions without holding the GIL, which could lead to a fatal
3179 error when they failed.
3180
Martin v. Löwisaabf4042008-08-02 07:20:25 +00003181- Issue #799428: Fix Tkinter.Misc._nametowidget to unwrap Tcl command objects.

Jesse Noller13e9d582008-07-16 14:32:36 +00003189- Issue #3125: Remove copy_reg in multiprocessing and replace it with
3190 ForkingPickler.register() to resolve conflict with ctypes.

Thomas Heller880f5292008-07-15 19:39:38 +00003194- Issue #3313: Fixed a crash when a failed dlopen() call does not set
3195 a valid dlerror() message.
3196
Thomas Heller2bad6572008-07-15 17:19:50 +00003197- Issue #3258: Fixed a crash when a ctypes POINTER type to an
3198 incomplete structure was created.
3199
Brett Cannon3d0b9f02008-07-13 01:15:07 +00003200- Issue #3339: dummy_thread.acquire() should not return None.
3201
Raymond Hettingerb01713e2008-07-10 14:34:57 +00003202- Issue #3285: Fractions from_float() and from_decimal() accept Integral arguments.
3203
Andrew M. Kuchlingcc3f2b12008-07-10 14:43:31 +00003204- Issue #3301: Bisect module behaved badly when lo was negative.
Raymond Hettinger3cd1e422008-07-10 14:03:19 +00003205
Amaury Forgeot d'Arc0f7cddc2008-07-06 21:34:39 +00003206- Issue #839496: SimpleHTTPServer used to open text files in text mode. This is
3207 both unnecessary (HTTP allows text content to be sent in several forms) and
Andrew M. Kuchlingcc3f2b12008-07-10 14:43:31 +00003208 wrong because the actual transmitted size could differ from the
Amaury Forgeot d'Arc0f7cddc2008-07-06 21:34:39 +00003209 content-length. The problem had been corrected in the 2.4 branch, but never

3617 mode or even as a 4-way universal binary (that is, PPC, i386,
Georg Brandl5cc774e2008-06-11 20:28:06 +00003618 PPC64 and x86_64 support in one binary).
Ronald Oussoren5640ce22008-06-05 12:58:24 +00003619
3620 This is controlled by the configure argument ``--with-universal-archs``:
3621
3622 - ``--with-universal-archs=all``: install 4-way universal
3623
3624 - ``--with-universal-archs=32-bit``: install 2-way universal, 32-bit (the default)
3625
3626 - ``--with-universal-archs=64-bit``: install 2-way universal, 64-bit
3627
3628 This option should be used in combination with ``--enable-universalsdk=``.
3629
3630 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 +00003680- Issue #1631171: Re-implement the 'warnings' module in C (the
3681 original Python code has been kept as backup). This will allow for
3682 using the 'warning's machinery in such places as the parser where
3683 use of pure Python code is not possible. Both the ``showarning()``
3684 and ``formatwarning()`` gain an optional 'line' argument which is
3685 not called by default for backwards-compatibility reasons. Setting
3686 ``warnings.showwarning()`` to an implementation that lacks support
3687 for the ``line`` argument will raise a DeprecationWarning.

3711
Gregory P. Smithd59fefb2008-04-22 08:11:33 +00003712- The getpass module has been improved on Unix. It now uses /dev/tty
3713 by default and uses stderr instead of stdout. A GetPassWarning is
3714 issued when input echo cannot be controlled.

Georg Brandl3ee81df2008-05-17 18:14:43 +00003729- Issue #2513: distutils on Windows is now capable of cross-compiling
Mark Hammond495cf992008-04-07 01:53:39 +00003730 extension modules between 32 and 64 bit platforms. See the distutls

Georg Brandl3ee81df2008-05-17 18:14:43 +00003750- Issue #2550: The approach used by client/server code for obtaining
3751 ports to listen on in network-oriented tests has been refined in an
3752 effort to facilitate running multiple instances of the entire
3753 regression test suite in parallel without issue.
3754 test_support.bind_port() has been fixed such that it will always
3755 return a unique port -- which wasn't always the case with the
3756 previous implementation, especially if socket options had been set
3757 that affected address reuse (i.e. SO_REUSEADDR, SO_REUSEPORT). The
3758 new implementation of bind_port() will actually raise an exception
3759 if it is passed an AF_INET/SOCK_STREAM socket with either the
3760 SO_REUSEADDR or SO_REUSEPORT socket option set. Furthermore, if
3761 available, bind_port() will set the SO_EXCLUSIVEADDRUSE option on
3762 the socket it's been passed. This currently only applies to
3763 Windows. This option prevents any other sockets from binding to the
3764 host/port we've bound to, thus removing the possibility of the
3765 'non-deterministic' behaviour, as Microsoft puts it, that occurs
3766 when a second SOCK_STREAM socket binds and accepts to a host/port
3767 that's already been bound by another socket. The optional preferred
3768 port parameter to bind_port() has been removed. Under no
3769 circumstances should tests be hard coding ports!
3770
3771 test_support.find_unused_port() has also been introduced, which will
3772 pass a temporary socket object to bind_port() in order to obtain an
3773 unused port. The temporary socket object is then closed and
3774 deleted, and the port is returned. This method should only be used
3775 for obtaining an unused port in order to pass to an external program
3776 (i.e. the -accept [port] argument to openssl's s_server mode) or as
3777 a parameter to a server-oriented class that doesn't give you direct
3778 access to the underlying socket used.
3779
3780 Finally, test_support.HOST has been introduced, which should be used
3781 for the host argument of any relevant socket calls (i.e. bind and
3782 connect).

4056Core and builtins
4057-----------------
4058
Fred Drakea8ee94b2008-03-01 02:45:07 +00004059- Issue #2051: pyc and pyo files are no longer created with permission
Barry Warsaw52973612008-03-01 02:23:38 +00004060 644. The mode is now inherited from the py file.
Christian Heimes40346852008-02-23 17:52:07 +00004061
Georg Brandlad61bc82008-02-23 15:11:18 +00004062- Issue #2067: file.__exit__() now calls subclasses' close() method.
4063
4064- Patch #1759: Backport of PEP 3129 class decorators.
Christian Heimes5224d282008-02-23 15:01:05 +00004065
Vinay Sajipb7edfc42008-04-02 21:10:23 +00004066- Issue #1881: An internal parser limit has been increased. Also see
Facundo Batistafc2d0102008-02-23 12:01:13 +00004067 issue 215555 for a discussion.
4068
Eric Smitha73fbe72008-02-23 03:09:44 +00004069- Added the future_builtins module, which contains hex() and oct().
4070 These are the PEP 3127 version of these functions, designed to be
4071 compatible with the hex() and oct() builtins from Python 3.0. They
4072 differ slightly in their output formats from the existing, unchanged
4073 Python 2.6 builtins. The expected usage of the future_builtins
4074 module is:
4075 from future_builtins import hex, oct
4076
Eric Smith7ef40bf2008-02-20 23:34:22 +00004077- Issue #1600: Modifed PyOS_ascii_formatd to use at most 2 digit
4078 exponents for exponents with absolute value < 100. Follows C99
4079 standard. This is a change on Windows, which would use 3 digits.
4080 Also, added 'n' to the formats that PyOS_ascii_formatd understands,
4081 so that any alterations it does to the resulting string will be
4082 available in stringlib/formatter.h (for float.__format__).
4083
Eric Smith5a3c1352008-02-19 13:21:56 +00004084- Implemented PEP 3101, Advanced String Formatting. This adds a new
4085 builtin format(); a format() method for str and unicode; a
4086 __format__() method to object, str, unicode, int, long, float, and
4087 datetime; the class string.Formatter; and the C API
4088 PyObject_Format().
4089
Georg Brandl3ee81df2008-05-17 18:14:43 +00004090- Fixed several potential crashes, all caused by specially crafted
4091 __del__ methods exploiting objects in temporarily inconsistent
4092 state.
Amaury Forgeot d'Arc632fad32008-02-16 20:55:24 +00004093
Vinay Sajipb7edfc42008-04-02 21:10:23 +00004094- Issue #2115: Important speedup in setting __slot__ attributes. Also
Georg Brandl3ee81df2008-05-17 18:14:43 +00004095 prevent a possible crash: an Abstract Base Class would try to access
4096 a slot on a registered virtual subclass.
Amaury Forgeot d'Arc60d6c7f2008-02-15 21:22:45 +00004097
Georg Brandl3ee81df2008-05-17 18:14:43 +00004098- Fixed repr() and str() of complex numbers with infinity or nan as
4099 real or imaginary part.
Christian Heimes2f0da532008-02-15 06:57:08 +00004100
Georg Brandl3ee81df2008-05-17 18:14:43 +00004101- Clear all free lists during a gc.collect() of the highest generation
4102 in order to allow pymalloc to free more arenas. Python may give back
4103 memory to the OS earlier.
Christian Heimes3b718a72008-02-14 12:47:33 +00004104
Georg Brandl3ee81df2008-05-17 18:14:43 +00004105- Issue #2045: Fix an infinite recursion triggered when printing a
4106 subclass of collections.defaultdict, if its default_factory is set
4107 to a bound method.
Amaury Forgeot d'Arcb01aa432008-02-08 00:56:02 +00004108
Christian Heimesf75dbef2008-02-08 00:11:31 +00004109- Fixed a minor memory leak in dictobject.c. The content of the free
4110 list was not freed on interpreter shutdown.
4111
Georg Brandl21e99f42010-03-07 15:23:59 +00004112- Limit free list of method and built-in function objects to 256
Georg Brandl3ee81df2008-05-17 18:14:43 +00004113 entries each.
Christian Heimes6075a822008-02-06 12:44:34 +00004114
Georg Brandl3ee81df2008-05-17 18:14:43 +00004115- Patch #1953: Added ``sys._compact_freelists()`` and the C API
4116 functions ``PyInt_CompactFreeList`` and ``PyFloat_CompactFreeList``
Christian Heimes422051a2008-02-04 18:00:12 +00004117 to compact the internal free lists of pre-allocted ints and floats.
4118
Georg Brandl3ee81df2008-05-17 18:14:43 +00004119- Issue #1983: Fixed return type of fork(), fork1() and forkpty()
4120 calls. Python expected the return type int but the fork familie
4121 returns pi_t.
Christian Heimes951cc0f2008-01-31 23:08:23 +00004122
Georg Brandl3ee81df2008-05-17 18:14:43 +00004123- Issue #1678380: Fix a bug that identifies 0j and -0j when they
4124 appear in the same code unit.
Mark Dickinson105be772008-01-31 22:17:37 +00004125
Georg Brandl3ee81df2008-05-17 18:14:43 +00004126- Issue #2025: Add tuple.count() and tuple.index() methods to comply
4127 with the collections.Sequence API.
Raymond Hettinger5b07ebc2008-02-07 00:54:20 +00004128
Georg Brandl3ee81df2008-05-17 18:14:43 +00004129- Patch #1970 by Antoine Pitrou: Speedup unicode whitespace and
4130 linebreak detection
Christian Heimes4d4f2702008-01-30 11:32:37 +00004131
Georg Brandl3ee81df2008-05-17 18:14:43 +00004132- Added ``PyType_ClearCache()`` and ``sys._clear_type_cache`` to clear
4133 the internal lookup cache for ref leak tests.
Christian Heimes908caac2008-01-27 23:34:59 +00004134
Georg Brandl3ee81df2008-05-17 18:14:43 +00004135- Patch #1473257: generator objects gain a gi_code attribute. This is
4136 the same object as the func_code attribute of the function that
4137 produced the generator.
Georg Brandl0cdf9a32008-01-26 14:14:20 +00004138
Georg Brandl3ee81df2008-05-17 18:14:43 +00004139- Issue #1920: "while 0" statements were completely removed by the
4140 compiler, even in the presence of an "else" clause, which is
4141 supposed to be run when the condition is false. Now the compiler
4142 correctly emits bytecode for the "else" suite.
Amaury Forgeot d'Arc31eaafe2008-01-24 22:59:25 +00004143
Guido van Rossumeead05f2008-01-24 18:21:02 +00004144- A few crashers fixed: weakref_in_del.py (issue #1377858);
4145 loosing_dict_ref.py (issue #1303614, test67.py);
4146 borrowed_ref_[34].py (not in tracker).
4147
Vinay Sajipd7cf32e2008-01-24 12:43:33 +00004148- Issue #1069410: The "can't load dll" message box on Windows is
Christian Heimesb2302ba2008-01-23 17:15:06 +00004149 suppressed while an extension is loaded by calling SetErrorMode in
4150 dynload_win.c. The error is still reported properly.
4151
Georg Brandl3ee81df2008-05-17 18:14:43 +00004152- Issue #1915: Python compiles with --enable-unicode=no again. However
Christian Heimes082c9b02008-01-23 14:20:50 +00004153 several extension methods and modules do not work without unicode
4154 support.
4155
Georg Brandl26543b12008-01-21 18:36:51 +00004156- Issue #1882: when compiling code from a string, encoding cookies in the
4157 second line of code were not always recognized correctly.
4158
Georg Brandl14404b62008-01-19 19:27:05 +00004159- Issue #1679: "0x" was taken as a valid integer literal.
4160
Georg Brandl6caad7d2008-01-26 14:19:22 +00004161- Issue #1865: ``bytes`` as an alias for ``str`` and b"" as an alias "" were
Christian Heimes288e89a2008-01-18 18:24:07 +00004162 added.
4163
Christian Heimesc94e2b52008-01-14 04:13:37 +00004164- sys.float_info / PyFloat_GetInfo: The floating point information
4165 object was converted from a dict to a specialized structseq object.
4166
Georg Brandl3ee81df2008-05-17 18:14:43 +00004167- Patch #1816: Added sys.flags structseq. It exposes the status of
4168 most command line arguments and PYTHON* environment variables.
Christian Heimesf31b69f2008-01-14 03:42:48 +00004169
Georg Brandl3ee81df2008-05-17 18:14:43 +00004170- Objects/structseq.c: Implemented new structseq representation. The
4171 patch makes structseqs (e.g. the return value of os.stat) more
4172 readable.
Christian Heimes9c201962008-01-14 03:33:52 +00004173
Georg Brandl3ee81df2008-05-17 18:14:43 +00004174- Patch #1700288: added a type attribute cache that caches method
4175 accesses, resulting in speedups in heavily object-oriented code.
Amaury Forgeot d'Arce4c270c2008-01-14 00:29:41 +00004176
Neal Norwitz3fc15b82008-01-10 05:42:58 +00004177- Bug #1776: __import__() no longer accepts filenames on any platform.
4178 The first parameter to __import__() must be a valid module name.
Christian Heimes3403f152008-01-09 19:56:33 +00004179
Georg Brandlaed6c662008-01-07 17:25:53 +00004180- Patch #1668: renamed THREADDEBUG envvar to PYTHONTHREADDEBUG.
4181
Georg Brandl3ee81df2008-05-17 18:14:43 +00004182- Patch #602345: Add -B command line option, PYTHONDONTWRITEBYTECODE
4183 envvar and sys.dont_write_bytecode attribute. All these can be set
4184 to forbid Python to attempt to write compiled bytecode files.
Georg Brandl2da0fce2008-01-07 17:09:35 +00004185
Georg Brandl3ee81df2008-05-17 18:14:43 +00004186- Improve some exception messages when Windows fails to load an
4187 extension module. Now we get for example '%1 is not a valid Win32
4188 application' instead of 'error code 193'.
Amaury Forgeot d'Arce0b76952008-01-04 02:04:15 +00004189
Georg Brandl3ee81df2008-05-17 18:14:43 +00004190- Bug #1481296: Fixed long(float('nan')) != 0L.

Georg Brandl3ee81df2008-05-17 18:14:43 +00004192- Issue #1640: Added math.isinf(x), math.isnan(x) and math.copysign(x,
4193 y) functions.
Christian Heimese2ca4242008-01-03 20:23:15 +00004194
Christian Heimes0a8143f2007-12-18 23:22:54 +00004195- Issue #1635: Platform independent creation and representation of NaN
Georg Brandl3ee81df2008-05-17 18:14:43 +00004196 and INF. float("nan"), float("inf") and float("-inf") now work on
4197 every platform with IEEE 754 semantics.
Christian Heimes0a8143f2007-12-18 23:22:54 +00004198
Georg Brandl3ee81df2008-05-17 18:14:43 +00004199- Compiler now generates simpler and faster code for dictionary
4200 literals. The oparg for BUILD_MAP now indicates an estimated
4201 dictionary size. There is a new opcode, STORE_MAP, for adding
4202 entries to the dictionary.
Raymond Hettingerfd7ed402007-12-18 21:24:09 +00004203
Georg Brandl3ee81df2008-05-17 18:14:43 +00004204- Issue #1638: %zd configure test fails on Linux.

4210 is not found.
Skip Montanaro26015492007-12-08 15:33:24 +00004211
Andrew M. Kuchling395fe442007-12-05 13:27:20 +00004212- Issue #1553: An erroneous __length_hint__ can make list() raise a
Christian Heimes7cc1c6f2007-12-05 12:52:34 +00004213 SystemError.
4214
Nick Coghlanef01d822007-12-03 12:55:17 +00004215- PEP 366: Allow explicit relative imports when executing modules
4216 inside packages with the -m switch via a new module level
4217 __package__ attribute.
4218
Georg Brandl3ee81df2008-05-17 18:14:43 +00004219- Issue #1402: Fix a crash on exit, when another thread is still
4220 running, and if the deallocation of its frames somehow calls the
4221 PyGILState_Ensure() / PyGILState_Release() functions.
Amaury Forgeot d'Arcbe49a902007-11-30 20:37:22 +00004222

4232 file can now be directly executed by passing their name to the
4233 interpreter. The directory/zipfile is automatically inserted as the
4234 first entry in sys.path.
Nick Coghlan327a39b2007-11-18 11:56:28 +00004235
Georg Brandl3ee81df2008-05-17 18:14:43 +00004236- Issue #1265: Fix a problem with sys.settrace, if the tracing
4237 function uses a generator expression when at the same time the
4238 executed code is closing a paused generator.
Amaury Forgeot d'Arc0d75f092007-11-13 21:54:28 +00004239
Raymond Hettinger1760c8a2007-11-08 02:52:43 +00004240- sets and frozensets now have an isdisjoint() method.
4241
Raymond Hettinger3f8caa32007-10-24 01:28:33 +00004242- optimize the performance of builtin.sum().

Neal Norwitz44f326e2007-10-05 05:29:17 +00004244- Fix warnings found by the new version of the Coverity checker.
4245
Georg Brandl21e99f42010-03-07 15:23:59 +00004246- The enumerate() built-in function is no longer bounded to sequences
Georg Brandl3ee81df2008-05-17 18:14:43 +00004247 smaller than LONG_MAX. Formerly, it raised an OverflowError. Now,
4248 automatically shifts from ints to longs.
Raymond Hettinger8f669372007-10-03 21:18:11 +00004249
Georg Brandl3ee81df2008-05-17 18:14:43 +00004250- Issue #1686386: Tuple's tp_repr did not take into account the
4251 possibility of having a self-referential tuple, which is possible
4252 from C code. Nor did object's tp_str consider that a type's tp_str
4253 could do something that could lead to an inifinite recursion.
4254 Py_ReprEnter() and Py_EnterRecursiveCall(), respectively, fixed the
4255 issues.
Brett Cannon0b14f242007-09-30 19:45:10 +00004256
Georg Brandl3ee81df2008-05-17 18:14:43 +00004257- Issue #1164: It was possible to trigger deadlock when using the
4258 'print' statement to write to a file since the GIL was not released
4259 as needed. Now PyObject_Print() does the right thing along with
4260 various tp_print implementations of the built-in types and those in
4261 the collections module.
Brett Cannon01531592007-09-17 03:28:34 +00004262
Georg Brandl3ee81df2008-05-17 18:14:43 +00004263- Issue #1147: Exceptions were directly allowing string exceptions in
4264 their throw() method even though string exceptions no longer
4265 allowed.
Brett Cannon4c20bc42007-09-11 21:02:28 +00004266

Brett Cannon1e534b52007-09-07 04:18:30 +00004270- Issue #1202533: Fix infinite recursion calls triggered by calls to
Georg Brandl3ee81df2008-05-17 18:14:43 +00004271 PyObject_Call() never calling back out to Python code to trigger
4272 recursion depth updates/checks. Required the creation of a static
4273 RuntimeError instance in case normalizing an exception put the
4274 recursion check value past its limit. Fixes crashers
4275 infinite_rec_(1|2|4|5).py.
Brett Cannon1e534b52007-09-07 04:18:30 +00004276
Georg Brandl3ee81df2008-05-17 18:14:43 +00004277- Patch #1031213: Decode source line in SyntaxErrors back to its

4281 with %G.
4282
Georg Brandl3ee81df2008-05-17 18:14:43 +00004283- Prevent expandtabs() on string and unicode objects from causing a
4284 segfault when a large width is passed on 32-bit platforms.

Neal Norwitz0ac60192007-05-27 04:08:54 +00004290- Add new attribute names for function objects. All the func_* become
Georg Brandl3ee81df2008-05-17 18:14:43 +00004291 __*__ attributes. (Some already existed, e.g., __doc__ and
4292 __name__.)
Neal Norwitz0ac60192007-05-27 04:08:54 +00004293
Neal Norwitz8b2bfbc2007-05-23 06:35:32 +00004294- Add -3 option to the interpreter to warn about features that are
4295 deprecated and will be changed/removed in Python 3.0.
4296
Georg Brandl2134e752007-05-21 20:34:16 +00004297- Patch #1686487: you can now pass any mapping after '**' in function
4298 calls.
4299
Collin Winter62903052007-05-18 23:11:24 +00004300- except clauses may now be spelled either "except E, target:" or
Georg Brandl3ee81df2008-05-17 18:14:43 +00004301 "except E as target:". This is to provide forwards compatibility
4302 with Python 3.0.
Collin Winter62903052007-05-18 23:11:24 +00004303
Brett Cannon229cee22007-05-05 01:34:02 +00004304- Deprecate BaseException.message as per PEP 352.
4305
Georg Brandl3ee81df2008-05-17 18:14:43 +00004306- Issue #1303614: don't expose object's __dict__ when the dict is
Georg Brandl21e99f42010-03-07 15:23:59 +00004307 inherited from a built-in base.
Armin Rigo9790a272007-05-02 19:23:31 +00004308
Vinay Sajip8549ce32007-05-06 17:53:37 +00004309- When __slots__ are set to a unicode string, make it work the same as
Neal Norwitzcbd9ee62007-04-14 05:25:50 +00004310 setting a plain string, ie don't expand to single letter identifiers.
4311
Raymond Hettinger13936692007-04-11 18:40:58 +00004312- Request #1191699: Slices can now be pickled.
4313
Raymond Hettinger4db5fe92007-04-12 04:10:00 +00004314- Request #1193128: str.translate() now allows a None argument for
4315 translations that only remove characters without re-mapping the
4316 remaining characters.
4317
Georg Brandl5cb76c12007-03-21 09:00:39 +00004318- Patch #1682205: a TypeError while unpacking an iterable is no longer
4319 masked by a generic one with the message "unpack non-sequence".
4320
Neal Norwitzaa754b72007-03-21 06:39:48 +00004321- Remove unused file Python/fmod.c.
4322
Guido van Rossum143b5642007-03-23 04:58:42 +00004323- Bug #1683368: The object.__init__() and object.__new__() methods are
4324 now stricter in rejecting excess arguments. The only time when
4325 either allows excess arguments is when it is not overridden and the
4326 other one is. For backwards compatibility, when both are
4327 overridden, it is a deprecation warning (for now; maybe a Py3k
Guido van Rossum234b1ff2007-03-23 19:39:01 +00004328 warning later). Also, type.__init__() insists on the same signature
4329 as supported by type.__new__().
Guido van Rossum143b5642007-03-23 04:58:42 +00004330
Georg Brandl3ee81df2008-05-17 18:14:43 +00004331- Patch #1675423: PyComplex_AsCComplex() now tries to convert an
4332 object to complex using its __complex__() method before falling back
4333 to the __float__() method. Therefore, the functions in the cmath
4334 module now can operate on objects that define a __complex__()
4335 method.
Georg Brandl2b869942007-03-17 16:08:45 +00004336
Georg Brandl3ee81df2008-05-17 18:14:43 +00004337- Patch #1623563: allow __class__ assignment for classes with
4338 __slots__. The old and the new class are still required to have the
4339 same slot names.
Žiga Seilnacht6f2d09c2007-03-16 11:59:38 +00004340

4345 ``object.__reduce_ex__()`` is called with an object that is faking
4346 its type.
Žiga Seilnacht20f43d32007-03-15 11:44:55 +00004347
Georg Brandl3ee81df2008-05-17 18:14:43 +00004348- Patch #1680015: Don't modify __slots__ tuple if it contains an
4349 unicode name.

Georg Brandl5240d742007-03-13 20:46:32 +00004351- Patch #1444529: the builtin compile() now accepts keyword arguments.
4352
Georg Brandl7b9c5552007-03-12 14:30:05 +00004353- Bug #1678647: write a newline after printing an exception in any
4354 case, even when converting the value to a string failed.
4355
Georg Brandl871f1bc2007-03-12 13:17:36 +00004356- The dir() function has been extended to call the __dir__() method on
Georg Brandl3ee81df2008-05-17 18:14:43 +00004357 its argument, if it exists. If not, it will work like before. This
4358 allows customizing the output of dir() in the presence of a
4359 __getattr__().
Georg Brandl871f1bc2007-03-12 13:17:36 +00004360
Collin Winter276887b2007-03-12 16:11:39 +00004361- Patch #922167: Python no longer segfaults when faced with infinitely
4362 self-recursive reload() calls (as reported by bug #742342).
4363

4368 parthensized forms. This means complex(repr(x)) now works instead of
4369 raising a ValueError.
Collin Wintere38051d2007-03-09 20:33:07 +00004370
Georg Brandlaa2321b2007-03-07 00:40:28 +00004371- Patch #703779: unset __file__ in __main__ after running a file. This
Georg Brandl3ee81df2008-05-17 18:14:43 +00004372 makes the filenames the warning module prints much more sensible
4373 when a PYTHONSTARTUP file is used.
Georg Brandlaa2321b2007-03-07 00:40:28 +00004374
Georg Brandl49aafc92007-03-07 00:34:46 +00004375- Variant of patch #697613: don't exit the interpreter on a SystemExit
4376 exception if the -i command line option or PYTHONINSPECT environment
Georg Brandl3ee81df2008-05-17 18:14:43 +00004377 variable is given, but break into the interactive interpreter just
4378 like on other exceptions or normal program exit.

4384 condition.
Georg Brandl098cd692007-03-06 12:17:50 +00004385
Georg Brandl0fca97a2007-03-05 22:28:08 +00004386- Patch #1674228: when assigning a slice (old-style), check for the
4387 sq_ass_slice instead of the sq_slice slot.
4388
Georg Brandl3ee81df2008-05-17 18:14:43 +00004389- When printing an unraisable error, don't print exceptions. before
4390 the name. This duplicates the behavior whening normally printing
4391 exceptions.
Neal Norwitz88516a62007-02-26 22:41:45 +00004392
Georg Brandl3ee81df2008-05-17 18:14:43 +00004393- Bug #1653736: Properly discard third argument to

Georg Brandl3ee81df2008-05-17 18:14:43 +00004399- Bug #1377858: Fix the segfaulting of the interpreter when an object
4400 created a weakref on itself during a __del__ call for new-style
4401 classes (classic classes still have the bug).
Brett Cannonf5bee302007-01-23 23:21:22 +00004402

5000 Python would crash instead of raising an error.
5001

5014
Georg Brandl3ee81df2008-05-17 18:14:43 +00005015- unittest now verifies more of its assumptions. In particular,
5016 TestCase and TestSuite subclasses (not instances) are no longer
5017 accepted in TestSuite.addTest(). This should cause no
5018 incompatibility since it never made sense with ordinary subclasses
5019 -- the failure just occurred later, with a more cumbersome
5020 exception.

Georg Brandl3ee81df2008-05-17 18:14:43 +00005301- Issue #829951: In the smtplib module, SMTP.starttls() now complies
5302 with RFC 3207 and forgets any knowledge obtained from the server not
5303 obtained from the TLS negotiation itself. Patch contributed by Bill
5304 Fenner.
Gregory P. Smith2b3ba582008-01-17 08:03:17 +00005305
Georg Brandl3ee81df2008-05-17 18:14:43 +00005306- Issue #1339: The smtplib.SMTP class has been refactored a bit such
Gregory P. Smithbde4ae42008-01-17 08:35:49 +00005307 that the SMTP.starttls() caller no longer needs to call ehlo()
5308 beforehand. SMTP.starttls() now raises an exception of the server
Georg Brandl3ee81df2008-05-17 18:14:43 +00005309 does not claim to support starttls. Adds the
5310 SMTP.ehlo_or_helo_if_needed() method. Patch contributed by Bill

5391 complex, tuple, list, dict, set, and frozenset. Formerly, it would
5392 silently miscode subclasses of those types. Now, it raises a
5393 ValueError instead.
Raymond Hettinger12e94202007-11-07 01:13:09 +00005394

Georg Brandl3ee81df2008-05-17 18:14:43 +00005409 time so that opening a database previously created with the DB_DUP
5410 or DB_DUPSORT flag set will keep the proper behavior on subsequent
5411 opens. Specifically: dictionary assignment to a DB object will
5412 replace all values for a given key when the database allows
5413 duplicate values. DB users should use DB.put(k, v) when they want
5414 to store duplicates; not DB[k] = v.
Gregory P. Smithec10a4a2007-11-05 02:32:26 +00005415

5421 characters with ASCII value less than 32. Also, it correctly quotes
5422 dots only if they occur on a single line, as opposed to the previous
5423 behavior of quoting dots if they are the second character of any
5424 line.
Georg Brandl4aef7272007-03-13 22:49:43 +00005425

Neal Norwitz92422fb2006-08-18 03:57:54 +00005746C API
5747-----
5748
Georg Brandl3ee81df2008-05-17 18:14:43 +00005749- Unified naming convention for free lists and their limits. All free
5750 lists in Object/ are named ``free_list``, the counter ``numfree``
5751 and the upper limit is a macro ``PyName_MAXFREELIST`` inside an
5752 #ifndef block.
Christian Heimes5b970ad2008-02-06 13:33:44 +00005753
Georg Brandl3ee81df2008-05-17 18:14:43 +00005754- ``PySet_Add()`` can now modify a newly created frozenset. Similarly
5755 to ``PyTuple_SetItem``, it can be used to populate a brand new
5756 frozenset; but it does not steal a reference to the added item.
Amaury Forgeot d'Arccab3d982008-02-03 22:51:43 +00005757
Vinay Sajipb7edfc42008-04-02 21:10:23 +00005758- Added ``PySet_Check()`` and ``PyFrozenSet_Check()`` to the set API.

Georg Brandl3ee81df2008-05-17 18:14:43 +00005760- Backport of PyUnicode_FromString(), _FromStringAndSize(), _Format
5761 and _FormatV from Python 3.0. Made PyLong_AsSsize_t and
5762 PyLong_FromSsize_t public functions.
Georg Brandl6caad7d2008-01-26 14:19:22 +00005763
5764- Patch #1720595: add T_BOOL to the range of structmember types.
5765
5766- Issue #1534: Added ``PyFloat_GetMax()``, ``PyFloat_GetMin()`` and
5767 ``PyFloat_GetInfo()`` to the float API.
5768
Georg Brandl3ee81df2008-05-17 18:14:43 +00005769- Issue #1521: On 64bit platforms, using PyArgs_ParseTuple with the t#
5770 of w# format code incorrectly truncated the length to an int, even
5771 when PY_SSIZE_T_CLEAN is set. The str.decode method used to return
5772 incorrect results with huge strings.
Georg Brandl6caad7d2008-01-26 14:19:22 +00005773
Georg Brandl3ee81df2008-05-17 18:14:43 +00005774- Issue #1629: Renamed Py_Size, Py_Type and Py_Refcnt to Py_SIZE,
5775 Py_TYPE and Py_REFCNT.

Georg Brandl3ee81df2008-05-17 18:14:43 +00005777- PEP 3123: Provide forward compatibility with Python 3.0, while
5778 keeping backwards compatibility. Add Py_Refcnt, Py_Type, Py_Size,
5779 and PyVarObject_HEAD_INIT.
Georg Brandl6caad7d2008-01-26 14:19:22 +00005780
Georg Brandl3ee81df2008-05-17 18:14:43 +00005781- Py_ssize_t fields work in structmember when HAVE_LONG_LONG is not
5782 defined.
Georg Brandl6caad7d2008-01-26 14:19:22 +00005783
5784- Patch #1733960: Allow T_LONGLONG to accept ints.
5785
5786- T_PYSSIZET can now be used in PyMemberDef lists for Py_ssize_t members.
5787
Christian Heimes000a0742008-01-03 22:16:32 +00005788- Added a new API function ``PyImport_ImportModuleNoBlock``.

5791
5792- Fix some leftovers from the conversion from int to Py_ssize_t
5793 (relevant to strings and sequences of more than 2**31 items).
5794
5795- Make _PyGILState_NoteThreadState() static, it was not used anywhere
5796 outside of pystate.c and should not be necessary.
5797
Georg Brandl3ee81df2008-05-17 18:14:43 +00005798- ``PyImport_Import`` and ``PyImport_ImportModule`` now always do
5799 absolute imports. In earlier versions they might have used relative
5800 imports under some conditions.
Christian Heimes000a0742008-01-03 22:16:32 +00005801
Georg Brandl3ee81df2008-05-17 18:14:43 +00005802- Added case insensitive comparison methods ``PyOS_stricmp(char*,
5803 char*)`` and ``PyOS_strnicmp(char*, char*, Py_ssize_t)``.
Christian Heimes000a0742008-01-03 22:16:32 +00005804
Georg Brandl3ee81df2008-05-17 18:14:43 +00005805- Bug #1542693: remove semi-colon at end of PyImport_ImportModuleEx

5811
Georg Brandl3ee81df2008-05-17 18:14:43 +00005812- Patch #1706: Drop support for Win9x, WinME and NT4. Python now
5813 requires Windows 2000 or greater. The _WINVER and NTDDI_VERSION
5814 macros are set to Win2k for x86/32bit builds and WinXP for AMD64
5815 builds.
Christian Heimes95d64472008-02-09 19:55:22 +00005816
Georg Brandl3ee81df2008-05-17 18:14:43 +00005817- Conditionalize definition of _CRT_SECURE_NO_DEPRECATE and

Georg Brandl3ee81df2008-05-17 18:14:43 +00005830- Removed the macfs module. It had been deprecated since Python 2.5.
5831 This lead to the deprecation of macostools.touched() as it relied
5832 solely on macfs and was a no-op under OS X.
