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 +0000331- Issue #8300: When passing a non-integer argument to struct.pack with any
332 integer format code, struct.pack first attempts to convert the non-integer
333 using its __index__ method. If that method is non-existent or raises
334 TypeError it goes on to try the __int__ method, as described below.
335
Georg Brandlba83f822010-03-14 09:50:54 +0000336- Issue #1530559: When passing a non-integer argument to struct.pack with *any*
337 integer format code (one of 'bBhHiIlLqQ'), struct.pack attempts to use the
338 argument's __int__ method to convert to an integer before packing. It also
339 produces a DeprecationWarning in this case. (In Python 2.6, the behaviour
340 was inconsistent: __int__ was used for some integer codes but not for others,
341 and the set of integer codes for which it was used differed between native
342 packing and standard packing.)

Georg Brandlba83f822010-03-14 09:50:54 +0000547- Issue #7712: test_support gained a new ``temp_cwd`` context manager which is
548 now also used by regrtest to run all the tests in a temporary directory. The
549 original CWD is saved in ``test.test_support.SAVEDCWD``. Thanks to Florent
550 Xicluna who helped with the patch.

567 and read operations on write-only file objects. On Windows, the system C
Georg Brandlba83f822010-03-14 09:50:54 +0000568 library would return a bogus result; on Solaris, it was possible to crash the
569 interpreter. Patch by Stefan Krah.

Georg Brandlba83f822010-03-14 09:50:54 +0000582- Issue #7766: Change ``sys.getwindowsversion()`` return value to a named tuple
583 and add the additional members returned in an OSVERSIONINFOEX structure. The
584 new members are service_pack_major, service_pack_minor, suite_mask, and
585 product_type.

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

622 XML processing instructions and comments. These raw characters are allowed
623 by the XML specification, and are necessary when outputting e.g. PHP code in
624 a processing instruction. Patch by Neil Muller.

Antoine Pitroud840e512010-02-04 20:20:18 +0000632- Issue #4772: Raise a ValueError when an unknown Bluetooth protocol is
Georg Brandlba83f822010-03-14 09:50:54 +0000633 specified, rather than fall through to AF_PACKET (in the ``socket`` module).
Antoine Pitroud840e512010-02-04 20:20:18 +0000634 Also, raise ValueError rather than TypeError when an unknown TIPC address
635 type is specified. Patch by Brian Curtin.

Antoine Pitrouf3fa0742010-01-31 22:26:04 +0000639- Issue #6939: Fix file I/O objects in the `io` module to keep the original
Georg Brandlba83f822010-03-14 09:50:54 +0000640 file position when calling `truncate()`. It would previously change the file
641 position to the given argument, which goes against the tradition of
Antoine Pitrouf3fa0742010-01-31 22:26:04 +0000642 ftruncate() and other truncation APIs. Patch by Pascal Chambon.
643
Benjamin Petersone06f7112010-01-28 02:15:02 +0000644- UserDict is now a new-style class.
645
Georg Brandlba83f822010-03-14 09:50:54 +0000646- Issue #7610: Reworked implementation of the internal ``zipfile.ZipExtFile``
647 class used to represent files stored inside an archive. The new
648 implementation is significantly faster and can be wrapped in a
649 ``io.BufferedReader`` object for more speedups. It also solves an issue
650 where interleaved calls to ``read()`` and ``readline()`` give wrong results.
651 Patch by Nir Aides.

659 when the release file is empty.
Benjamin Petersona43f34c2010-01-25 03:31:13 +0000660
Georg Brandlba83f822010-03-14 09:50:54 +0000661- Issue #7748: Since unicode values are supported for some metadata options in
662 Distutils, the DistributionMetadata get_* methods will now return an utf-8
663 encoded string for them. This ensures that the upload and register commands
664 send the correct values to PyPI without any error.

Georg Brandlba83f822010-03-14 09:50:54 +0000666- Issue #1670765: Prevent ``email.generator.Generator`` from re-wrapping
R. David Murrayed44dfa2010-01-16 05:15:17 +0000667 headers in multipart/signed MIME parts, which fixes one of the sources of

740
Georg Brandlba83f822010-03-14 09:50:54 +0000741- The ``__complex__()`` method is now looked up on the class of instances to
742 make it consistent with other special methods.
Benjamin Petersonecdae192010-01-04 00:43:01 +0000743
Antoine Pitrou5b7139a2010-01-02 21:12:58 +0000744- Issue #7462: Implement the stringlib fast search algorithm for the `rfind`,
745 `rindex`, `rsplit` and `rpartition` methods. Patch by Florent Xicluna.
746
Mark Dickinson1b34d252010-01-01 17:27:30 +0000747- Issue #5080: A number of functions and methods previously produced a
Georg Brandlba83f822010-03-14 09:50:54 +0000748 DeprecationWarning when passed a float argument where an integer was expected.
749 These functions and methods now raise TypeError instead. The majority of the
750 effects of this change are in the extension modules, but some core functions
751 and methods are affected: notably the 'chr', 'range' and 'xrange' builtins,
752 and many unicode/str methods.

Georg Brandlba83f822010-03-14 09:50:54 +0000765- Issue #1811: Improve accuracy and cross-platform consistency for true division
766 of integers: the result of a/b is now correctly rounded for ints a and b (at
767 least on IEEE 754 platforms), and in particular does not depend on the
768 internal representation of a long.

776
Georg Brandlba83f822010-03-14 09:50:54 +0000777 These executables now work properly with the arch(1) command: ``arch -ppc
778 python`` will start a universal binary version of python in PPC mode (unlike
779 previous releases).

Georg Brandlba83f822010-03-14 09:50:54 +0000935- Issue #7117: ``repr(x)`` for a float x returns a result based on the shortest
936 decimal string that's guaranteed to round back to x under correct rounding
937 (with round-half-to-even rounding mode). Previously it gave a string based on
938 rounding x to 17 decimal digits. repr(x) for a complex number behaves
939 similarly. On platforms where the correctly-rounded strtod and dtoa code is
940 not supported (see below), repr is unchanged.
Mark Dickinsonb678de82009-11-19 18:41:49 +0000941
Georg Brandlba83f822010-03-14 09:50:54 +0000942- Issue #7117: On almost all platforms: float-to-string and string-to-float
943 conversions within Python are now correctly rounded. Places these conversions
944 occur include: str for floats and complex numbers; the float and complex
945 constructors; old-style and new-style numeric formatting; serialization and
946 deserialization of floats and complex numbers using marshal, pickle and json;
947 parsing of float and imaginary literals in Python code; Decimal-to-float
948 conversion.
Mark Dickinsonb678de82009-11-19 18:41:49 +0000949
Georg Brandlba83f822010-03-14 09:50:54 +0000950 The conversions use a Python-adapted version of David Gay's well-known dtoa.c,
951 providing correctly-rounded strtod and dtoa C functions. This code is
952 supported on Windows, and on Unix-like platforms using gcc, icc or suncc as
953 the C compiler. There may be a small number of platforms on which correct
954 operation of this code cannot be guaranteed, so the code is not used: notably,
955 this applies to platforms where the C double format is not IEEE 754 binary64,
956 and to platforms on x86 hardware where the x87 FPU is set to 64-bit precision
957 and Python's configure script is unable to determine how to change the FPU
958 precision. On these platforms conversions use the platform strtod and dtoa,
959 as before.

Georg Brandlba83f822010-03-14 09:50:54 +0000961- Issue #7117: Backport round implementation from Python 3.x. ``round()`` now
962 uses the correctly-rounded string <-> float conversions described above (when
963 available), and so produces correctly rounded results that will display nicely
964 under the float repr. There are two related small changes: (1) round now
965 accepts any class with an ``__index__()`` method for its second argument (but
966 no longer accepts floats for the second argument), and (2) an excessively
967 large second integer argument (e.g., ``round(1.234, 10**100)``) no longer
968 raises an exception.

Georg Brandlba83f822010-03-14 09:50:54 +00001111 (1) inf and nan strings with trailing whitespace were incorrectly rejected;
1112 (2) parsing of strings representing infinities and nans was locale aware; and
1113 (3) the interpretation of fromhex('-nan') didn't match that of float('-nan').

Georg Brandlba83f822010-03-14 09:50:54 +00001115- Issue #5920: For ``float.__format__()``, change the behavior with the empty
1116 presentation type (that is, not one of 'e', 'f', 'g', or 'n') to be like 'g'
1117 but with at least one decimal point and with a default precision
1118 of 12. Previously, the behavior the same but with a default precision of 6.
1119 This more closely matches ``str()``, and reduces surprises when adding
1120 alignment flags to the empty presentation type. This also affects the new
1121 complex.__format__ in the same way.
1122
1123- Issue #5890: In subclasses of 'property' the __doc__ attribute was shadowed by

1318
Georg Brandlba83f822010-03-14 09:50:54 +00001319- Issue #4233: Changed semantic of ``_fileio.FileIO``'s ``close()`` method on
1320 file objects with closefd=False. The file descriptor is still kept open but
1321 the file object behaves like a closed file. The ``FileIO`` object also got a

Benjamin Peterson399b1fe2008-10-25 02:53:28 +00001342- Using ``nonlocal`` as a variable name will now raise a Py3k SyntaxWarning

Georg Brandlba83f822010-03-14 09:50:54 +00001345- On windows, ``os.chdir()`` given unicode was not working if
1346 GetCurrentDirectoryW returned a path longer than MAX_PATH. (But It's doubtful
1347 this code path is really executed because I cannot move to such directory on
1348 win2k)

Georg Brandlba83f822010-03-14 09:50:54 +00001350- Issue #4069: When ``set.remove(element)`` is used with a set element, the
1351 element is temporarily replaced with an equivalent frozenset. But the
1352 eventual KeyError would always report the empty ``frozenset()`` as the missing
1353 key. Now it correctly refers to the initial element.

Walter Dörwalded960ac2009-05-03 22:36:33 +00001373- Issue #5108: Handle %s like %S and %R in PyUnicode_FromFormatV(): Call
1374 PyUnicode_DecodeUTF8() once, remember the result and output it in a second
1375 step. This avoids problems with counting UTF-8 bytes that ignores the effect
1376 of using the replace error handler in PyUnicode_DecodeUTF8().
1377
Walter Dörwald726ba8e2009-05-06 14:32:35 +00001378- Issue #3739: The unicode-internal encoder now reports the number of characters

1380
Georg Brandlba83f822010-03-14 09:50:54 +00001381- Issue #2422: When compiled with the ``--with-valgrind`` option, the pymalloc

1383 gives improved memory leak detection when running under Valgrind, while taking
1384 advantage of pymalloc at other times.

Antoine Pitrou4698d992009-05-31 14:20:14 +00002631- Issue #6152: New option '-j'/'--multiprocess' for regrtest allows running
2632 regression tests in parallel, shortening the total runtime.

Georg Brandlba83f822010-03-14 09:50:54 +00002634- Issue #5354: New test support function import_fresh_module() makes it easy to
2635 import both normal and optimised versions of modules. test_heapq and
2636 test_warnings have been adjusted to use it, tests for other modules with both
2637 C and Python implementations in the stdlib can be adjusted to use it over
2638 time.

Georg Brandlba83f822010-03-14 09:50:54 +00002646- regrtest no longer treats ImportError as equivalent to SkipTest. Imports that
2647 should cause a test to be skipped are now done using import_module from test
2648 support, which does the conversion.

2750
Amaury Forgeot d'Arc05e34492008-09-10 22:04:45 +00002751- Issue #3743: In a few places, PY_FORMAT_SIZE_T was incorrectly used with
2752 PyString_FromFormat or PyErr_Format to display size_t values. The macro
2753 PY_FORMAT_SIZE_T is designed to select the correct format for the OS
2754 ``printf`` function, whereas PyString_FromFormat has an independent
2755 implementation and uses "%zd" on all platforms for size_t values.
2756 This makes a difference on win64, where ``printf`` needs "%Id" to display
2757 64bit values.

Benjamin Peterson97179b02008-09-09 20:55:01 +00002759- Issue #3634: _weakref.ref(Exception).__init__() gave invalid return value on

Antoine Pitroud4ae97b2008-08-29 18:39:48 +00002774 was correctly parsed but parsing of subsequent arguments failed.
2775
Vinay Sajip35e3b032008-09-01 14:33:59 +00002776- Issue #2534: speed up isinstance() and issubclass() by 50-70%, so as to
Antoine Pitrou0668c622008-08-26 22:42:08 +00002777 match Python 2.5 speed despite the __instancecheck__ / __subclasscheck__
2778 mechanism. In the process, fix a bug where isinstance() and issubclass(),
2779 when given a tuple of classes as second argument, were looking up
2780 __instancecheck__ / __subclasscheck__ on the tuple rather than on each
2781 type object.

2925Core and Builtins
2926-----------------
2927
Guido van Rossumf8402962008-08-20 15:01:50 +00002928- Issue #1878: Remove Py_TPFLAGS_HAVE_VERSION_TAG from
2929 Py_TPFLAGS_DEFAULT when not building the core. This means 3rd party
2930 extensions do not automatically benefit from the class attribute
2931 cache; they will have to explicitly add Py_TPFLAGS_HAVE_VERSION_TAG
2932 to their tp_flags field if they care. This is a backwards
2933 compatibility feature; in 3.0, all types will use the cache by
2934 default.
2935
Benjamin Petersonf647dc12008-08-20 01:27:30 +00002936- Keyword arguments can now follow starred arguments. (``f(a, *args,
2937 keyword=23)`` is now valid syntax.)
2938
Thomas Heller0ad5ae02008-08-19 19:25:04 +00002939- ctypes function pointers that are COM methods have a boolean True
2940 value again.
2941
Martin v. Löwisf91d46a2008-08-12 14:49:50 +00002942- Issue #3139: Make buffer-interface thread-safe wrt. PyArg_ParseTuple,
2943 by denying s# to parse objects that have a releasebuffer procedure,
2944 and introducing s*.
2945
Georg Brandl1e13ea92008-08-11 09:07:59 +00002946- Issue #3537: Fix an assertion failure when an empty but presized dict
2947 object was stored in the freelist.
2948
Mark Dickinsonb6467572008-08-04 21:30:09 +00002949- Issue #1481296: Make long(float('nan')) and int(float('nan')) raise
2950 ValueError consistently across platforms.
2951
Amaury Forgeot d'Arc39fd6722008-07-31 21:28:03 +00002952- Issue #3479: On platforms where sizeof(int) is smaller than sizeof(long)
2953 (64bit Unix, for example), unichr() would truncate its argument and return
2954 u'\x00' for unichr(2**32). Now it properly raises an OverflowError.
2955
Neal Norwitze7d8be82008-07-31 17:17:14 +00002956- Apply security patches from Apple.
2957
Amaury Forgeot d'Arc246daed2008-07-31 00:42:16 +00002958- Issue #2542: Now that issubclass() may call arbitrary code, ensure that
2959 PyErr_ExceptionMatches returns 0 when an exception occurs there.
2960
Antoine Pitrou92f82162008-07-25 22:22:08 +00002961- Issue #1819: function calls with several named parameters are now on
2962 average 35% faster (as measured by pybench).
2963
Amaury Forgeot d'Arce4921fe2008-07-21 22:00:38 +00002964- Issue #2378: An unexpected UnboundLocalError or NameError could appear when
2965 the python debugger steps into a class statement: the free variables (local
2966 variables defined in an outer scope) would be deleted from the outer scope.
2967
Gregory P. Smith0470bab2008-07-22 04:46:32 +00002968- Issue #2620: Overflow checking when allocating or reallocating memory
2969 was not always being done properly in some python types and extension
2970 modules. PyMem_MALLOC, PyMem_REALLOC, PyMem_NEW and PyMem_RESIZE have
2971 all been updated to perform better checks and places in the code that
2972 would previously leak memory on the error path when such an allocation
2973 failed have been fixed.

2976-------
2977
Hirokazu Yamamoto838c79f2008-08-20 13:14:07 +00002978- Issue #3612: Added some missing basic types in ctypes.wintypes.
2979
Benjamin Petersone977ad42008-08-20 01:42:01 +00002980- The methods ``is_in_tuple()``, ``is_vararg()``, and ``is_keywordarg()`` of
2981 symtable.Symbol have been deprecated for removal in 3.0 and the next release.
2982
Amaury Forgeot d'Arc351ffb82008-08-18 19:23:47 +00002983- Issue #2234: distutils failed for some versions of the cygwin compiler. The
2984 version reported by these tools does not necessarily follow the python
2985 version numbering scheme, so the module is less strict when parsing it.
2986
Nick Coghlanf70385a2008-08-18 12:42:46 +00002987- Issue #2235: Added Py3k warnings for types which will become unhashable
2988 under the stricter __hash__ inheritance rules in 3.0. Several types
2989 which did not meet the rules for hash invariants and were already
2990 unhashable in 3.0 have now been explicitly flagged as unhashable in
2991 2.6 as well (collections.Mapping, collections.Set, unittest.TestSuite,
2992 xml.dom.minidom.NamedNodeMap, numbers.Number, UserList.UserList)
2993
Brett Cannon88f801d2008-08-18 00:46:22 +00002994- Update __all__ for cookielib, csv, os, urllib2, and weakref to include things
2995 imported into the module but exposed as part of the module's API.
2996
Brett Cannon7b96f072008-08-18 00:41:11 +00002997- Remove an unneeded import of abc.ABCMeta from 'inspect'.
2998
Brett Cannon46225e72008-08-18 00:36:52 +00002999- Remove unneeded imports of 'sys' and 'warnings' from 'io'.
3000
Brett Cannon25c9d6a2008-08-17 22:10:11 +00003001- Remove unneeded imports of 'warnings' from shelve, filecmp, and dummy_thread.
3002
Hirokazu Yamamoto41a81eb2008-08-17 13:10:46 +00003003- Issue #3575: Incremental decoder's decode function now takes bytearray
3004 by using 's*' instead of 't#'.
3005
Mark Dickinson3e4caeb2009-02-21 20:27:01 +00003006- Issue #2222: Fixed reference leak when occurred os.rename()
Hirokazu Yamamoto7f30a682008-08-17 09:46:56 +00003007 fails unicode conversion on 2nd parameter. (windows only)
3008
Facundo Batista94f243a2008-08-17 03:38:39 +00003009- Issue 2464. urllib2 now supports a malformation in the URL received
3010 in a redirect.
3011
Brett Cannonabe423e2008-08-16 21:47:07 +00003012- Silence the DeprecationWarning raised when importing mimetools in
Brett Cannon721b1452008-08-16 22:00:27 +00003013 BaseHTTPServer, cgi (and rfc822), httplib.
Brett Cannonabe423e2008-08-16 21:47:07 +00003014
Facundo Batistaeb90b782008-08-16 14:44:07 +00003015- Issue #2776: fixed small issue when handling an URL with double slash
3016 after a 302 response in the case of not going through a proxy.
3017
Antoine Pitroub90a8be2008-08-15 21:03:21 +00003018- Issue #2676: in the email package, content-type parsing was hanging on
3019 pathological input because of quadratic or exponential behaviour of a
3020 regular expression.
3021
Antoine Pitrou11ec65d2008-08-14 21:04:30 +00003022- Issue #3476: binary buffered reading through the new "io" library is now
3023 thread-safe.
3024
Brett Cannonbf3157b2008-08-14 05:00:03 +00003025- Silence the DeprecationWarning of rfc822 when it is imported by mimetools
3026 since mimetools itself is deprecated. Because modules are cached, all
3027 subsequent imports of rfc822 will not raise a visible DeprecationWarning.
3028
Antoine Pitrou9fcd4b32008-08-11 17:21:36 +00003029- Issue #3134: shutil referenced undefined WindowsError symbol.
3030
Robert Schuppenies14646332008-08-10 11:01:53 +00003031- Issue #1342811: Fix leak in Tkinter.Menu.delete. Commands associated to
3032 menu entries were not deleted.
3033
Brett Cannon83e81842008-08-09 23:30:55 +00003034- Copied the implementation of reduce() to _functools.reduce() to have a
3035 version that did not raise a DeprecationWarning under -3.
3036
Antoine Pitrou76b8bee2008-08-09 17:27:23 +00003037- Issue #3205: When iterating over a BZ2File fails allocating memory, raise
3038 a MemoryError rather than silently stop the iteration.
3039
Guido van Rossum59ce9012008-08-09 14:55:34 +00003040- Issue #3487: sre "bytecode" validator. Passing invalid "re-bytecode"
3041 to _sre.compile() will now be rejected. This should not affect anybody
3042 since the re.compile() function never generates invalid re-bytecode.
3043
Skip Montanaroa032bf42008-08-08 22:52:51 +00003044- Issue #3436: Make csv.DictReader's fieldnames attribute a property so that
3045 upon first access it can be automatically initialized from the csv file if
3046 it wasn't initialized during instantiation.
3047
Brett Cannon3aa2a492008-08-06 22:28:09 +00003048- Issue #2338: Create imp.reload() to help with transitioning to Python 3.0 as
3049 the reload() built-in has been removed.
3050
Brett Cannon7e30b672008-08-04 21:52:25 +00003051- Changed code in the following modules/packages to remove warnings raised
Brett Cannonc1b76e42008-08-09 23:06:16 +00003052 while running under the ``-3`` flag: aifc, asynchat, asyncore, bdb, bsddb,
Brett Cannon047e4a92008-08-17 04:16:04 +00003053 ConfigParser, cookielib, csv, difflib, distutils, DocXMLRPCServer, email,
3054 filecmp, fileinput, inspect, logging, modulefinder, pdb, pickle, profile,
3055 pstats, pydoc, re, rlcompleter, SimpleXMLRPCServer, shelve, socket,
3056 subprocess, sqlite3, tarfile, Tkinter, test.test_support, textwrap,
3057 threading, tokenize, traceback, urlparse, wsgiref, xml, xmlrpclib.
Brett Cannon7e30b672008-08-04 21:52:25 +00003058
Lars Gustäbel727bd0b2008-08-02 11:26:39 +00003059- Issue #3039: Fix tarfile.TarFileCompat.writestr() which always
3060 raised an AttributeError.
3061
Benjamin Peterson01a24322008-07-28 23:35:27 +00003062- Issue #2523: Fix quadratic behaviour when read()ing a binary file without
Antoine Pitroude781a42008-08-09 12:43:23 +00003063 asking for a specific length. This problem only affected files opened
3064 using the new "io" module, not the built-in open() function.
Benjamin Peterson01a24322008-07-28 23:35:27 +00003065
Mark Dickinsonfe84cce2008-07-27 06:39:07 +00003066- Issue #3449: Update decimal module to use most recent specification
3067 (v. 1.68) and tests (v. 2.58) from IBM.
3068
Skip Montanarof9ac43f2008-07-27 00:50:41 +00003069- Issue 3437: Bug fix in robotparser parsing of Allow: lines.
3070
Raymond Hettinger8c664e82008-07-25 18:43:33 +00003071- Issue 1592: Improve error reporting when operations are attempted
3072 on a closed shelf.

3075
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00003076- Issue #3120: On 64-bit Windows the subprocess module was truncating handles.
3077
3078- Issue #3303: Fix a crash in locale.strcoll() when calling it with
3079 invalid arguments.
3080
3081- Issue #3302: Fix several crashes when calling locale's gettext functions
3082 with None arguments.
3083
3084- Issue #3389: Allow resolving dotted names for handlers in logging
3085 configuration files.
3086
3087- Deprecate the sunaudio module for removal in Python 3.0.
3088
Antoine Pitrou5fdfa3e2008-07-25 19:42:26 +00003089- Issue #3394: zipfile.writestr sets external attributes when passed a
3090 file name rather than a ZipInfo instance, so files are extracted with
3091 mode 0600 rather than 000 under Unix.
3092
Gregory P. Smitha36f8fe2008-08-04 00:13:29 +00003093- Issue #1857: subprocess.Popen.poll gained an additional _deadstate keyword
3094 argument in python 2.5, this broke code that subclassed Popen to include its
3095 own poll method. Fixed my moving _deadstate to an _internal_poll method.

3104
Nick Coghlan6e8fef02008-08-18 13:14:22 +00003105- Issue #2235: the C API function PyObject_HashNotImplemented and its
3106 interaction with the tp_hash slot (added in 2.6b2) are now documented
3107
Nick Coghlan2a0c2b12008-08-04 12:47:17 +00003108- Issue #643841: The language reference now provides more detailed
3109 coverage of the lookup process for special methods. The disclaimers
3110 regarding lack of coverage of new-style classes have also been
3111 removed, since the coverage is now fairly reasonable.

3120-----------------
3121
Georg Brandl3e483f62008-07-16 22:57:41 +00003122- Issue #3156: Fix inconsistent behavior of the bytearray type: all
3123 its methods now allow for items objects that can be converted to
3124 an integer using operator.index().
3125
Mark Dickinson64b7e502008-07-16 09:40:03 +00003126- Issue #3360: Fix incorrect parsing of '020000000000.0', which
3127 produced a ValueError instead of giving the correct float.
3128
Eric Smitha5fa5a22008-07-16 00:11:49 +00003129- Issue #3083: Add alternate (#) formatting for bin, oct, hex output
3130 for str.format(). This adds the prefix 0b, 0o, or 0x, respectively.
3131
Mark Dickinson7103aa42008-07-15 19:08:33 +00003132- Issue #3008: the float type has a new instance method 'float.hex'
3133 and a new class method 'float.fromhex' to convert floating-point
3134 numbers to and from hexadecimal strings, respectively.
3135
Nick Coghlan6d6bd442008-07-15 15:40:22 +00003136- Issue #2235: __hash__ is once again inherited by default. To allow
3137 collections.Hashable to remain meaningful in the presence of the
3138 default hash implementation (object.__hash__), it is now possible
3139 to explicit block inheritance of hash by setting __hash__=None at
3140 the Python level, or tp_hash=PyObject_HashNotImplemented at the C
3141 level.
3142
Nick Coghlanb028f502008-07-13 14:52:36 +00003143- Issue #3221: Issue a RuntimeWarning instead of raising SystemError if
3144 the parent module cannot be found while performing an absolute import.
3145 This means that an incorrectly defined __package__ attribute will
3146 now only prevent relative imports in that module rather than causing
3147 all imports from that module to fail.
3148
Nick Coghlan14ff9942008-07-08 14:21:42 +00003149- Issue #2517: Allow unicode messages in Exceptions again by correctly
3150 bypassing the instance dictionary when looking up __unicode__ on
3151 new-style classes.
3152
Amaury Forgeot d'Arcbdd941f2008-07-01 20:38:04 +00003153- Issue #3242: Fix a crash inside the print statement, if sys.stdout is
3154 set to a custom object whose write() method happens to install
3155 another file in sys.stdout.
3156
Amaury Forgeot d'Arc1f40c8a2008-06-30 22:42:40 +00003157- Issue #3088: Corrected a race condition in classes derived from
3158 threading.local: the first member set by a thread could be saved in
3159 another thread's dictionary.
3160
Mark Dickinson1ec2fcd2008-06-20 14:53:43 +00003161- Issue #3004: Minor change to slice.indices(): the start and stop
3162 arguments are now treated identically, making the behaviour easier
3163 to describe and understand. For example, slice(None, -10,
3164 1).indices(9) now returns (0, 0, 1) instead of (0, -1, 1), and
3165 slice(None, 10, -1).indices(10) returns (9, 9, -1) instead of (9,
3166 10, -1).
3167
Georg Brandl278fc502008-07-19 12:46:12 +00003168- Issue #3219: Calling a function with repeated keyword arguments,
3169 f(a=2, a=23), would not cause a syntax error. This was a regression
3170 from 2.4 caused by the switch to the new compiler.
Benjamin Peterson175e4d92008-07-01 19:34:52 +00003171
Georg Brandl278fc502008-07-19 12:46:12 +00003172- Issue #2862: Make int and float freelist management consistent with
3173 other freelists. Changes their CompactFreeList apis into
3174 ClearFreeList apis and calls them via gc.collect().

Thomas Heller57adf222008-08-14 19:10:48 +00003179- Issue #3554: ctypes.string_at and ctypes.wstring_at did call Python
3180 api functions without holding the GIL, which could lead to a fatal
3181 error when they failed.
3182
Martin v. Löwisaabf4042008-08-02 07:20:25 +00003183- Issue #799428: Fix Tkinter.Misc._nametowidget to unwrap Tcl command objects.

Jesse Noller13e9d582008-07-16 14:32:36 +00003191- Issue #3125: Remove copy_reg in multiprocessing and replace it with
3192 ForkingPickler.register() to resolve conflict with ctypes.
3193
Vinay Sajip51e65192008-07-18 09:01:10 +00003194- Issue #3090: Fixed ARCHFLAGS parsing on OS/X

Thomas Heller880f5292008-07-15 19:39:38 +00003196- Issue #3313: Fixed a crash when a failed dlopen() call does not set
3197 a valid dlerror() message.
3198
Thomas Heller2bad6572008-07-15 17:19:50 +00003199- Issue #3258: Fixed a crash when a ctypes POINTER type to an
3200 incomplete structure was created.
3201
Brett Cannon3d0b9f02008-07-13 01:15:07 +00003202- Issue #3339: dummy_thread.acquire() should not return None.
3203
Raymond Hettingerb01713e2008-07-10 14:34:57 +00003204- Issue #3285: Fractions from_float() and from_decimal() accept Integral arguments.
3205
Andrew M. Kuchlingcc3f2b12008-07-10 14:43:31 +00003206- Issue #3301: Bisect module behaved badly when lo was negative.
Raymond Hettinger3cd1e422008-07-10 14:03:19 +00003207
Amaury Forgeot d'Arc0f7cddc2008-07-06 21:34:39 +00003208- Issue #839496: SimpleHTTPServer used to open text files in text mode. This is
3209 both unnecessary (HTTP allows text content to be sent in several forms) and
Andrew M. Kuchlingcc3f2b12008-07-10 14:43:31 +00003210 wrong because the actual transmitted size could differ from the
Amaury Forgeot d'Arc0f7cddc2008-07-06 21:34:39 +00003211 content-length. The problem had been corrected in the 2.4 branch, but never

3617
Ronald Oussoren5640ce22008-06-05 12:58:24 +00003618- On MacOS X it is now possible to install the framework in 64-bit
3619 mode or even as a 4-way universal binary (that is, PPC, i386,
Georg Brandl5cc774e2008-06-11 20:28:06 +00003620 PPC64 and x86_64 support in one binary).
Ronald Oussoren5640ce22008-06-05 12:58:24 +00003621
3622 This is controlled by the configure argument ``--with-universal-archs``:
3623
3624 - ``--with-universal-archs=all``: install 4-way universal
3625
3626 - ``--with-universal-archs=32-bit``: install 2-way universal, 32-bit (the default)
3627
3628 - ``--with-universal-archs=64-bit``: install 2-way universal, 64-bit
3629
3630 This option should be used in combination with ``--enable-universalsdk=``.
3631
3632 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 +00003682- Issue #1631171: Re-implement the 'warnings' module in C (the
3683 original Python code has been kept as backup). This will allow for
3684 using the 'warning's machinery in such places as the parser where
3685 use of pure Python code is not possible. Both the ``showarning()``
3686 and ``formatwarning()`` gain an optional 'line' argument which is
3687 not called by default for backwards-compatibility reasons. Setting
3688 ``warnings.showwarning()`` to an implementation that lacks support
3689 for the ``line`` argument will raise a DeprecationWarning.

3713
Gregory P. Smithd59fefb2008-04-22 08:11:33 +00003714- The getpass module has been improved on Unix. It now uses /dev/tty
3715 by default and uses stderr instead of stdout. A GetPassWarning is
3716 issued when input echo cannot be controlled.

Georg Brandl3ee81df2008-05-17 18:14:43 +00003731- Issue #2513: distutils on Windows is now capable of cross-compiling
Mark Hammond495cf992008-04-07 01:53:39 +00003732 extension modules between 32 and 64 bit platforms. See the distutls

Georg Brandl3ee81df2008-05-17 18:14:43 +00003752- Issue #2550: The approach used by client/server code for obtaining
3753 ports to listen on in network-oriented tests has been refined in an
3754 effort to facilitate running multiple instances of the entire
3755 regression test suite in parallel without issue.
3756 test_support.bind_port() has been fixed such that it will always
3757 return a unique port -- which wasn't always the case with the
3758 previous implementation, especially if socket options had been set
3759 that affected address reuse (i.e. SO_REUSEADDR, SO_REUSEPORT). The
3760 new implementation of bind_port() will actually raise an exception
3761 if it is passed an AF_INET/SOCK_STREAM socket with either the
3762 SO_REUSEADDR or SO_REUSEPORT socket option set. Furthermore, if
3763 available, bind_port() will set the SO_EXCLUSIVEADDRUSE option on
3764 the socket it's been passed. This currently only applies to
3765 Windows. This option prevents any other sockets from binding to the
3766 host/port we've bound to, thus removing the possibility of the
3767 'non-deterministic' behaviour, as Microsoft puts it, that occurs
3768 when a second SOCK_STREAM socket binds and accepts to a host/port
3769 that's already been bound by another socket. The optional preferred
3770 port parameter to bind_port() has been removed. Under no
3771 circumstances should tests be hard coding ports!
3772
3773 test_support.find_unused_port() has also been introduced, which will
3774 pass a temporary socket object to bind_port() in order to obtain an
3775 unused port. The temporary socket object is then closed and
3776 deleted, and the port is returned. This method should only be used
3777 for obtaining an unused port in order to pass to an external program
3778 (i.e. the -accept [port] argument to openssl's s_server mode) or as
3779 a parameter to a server-oriented class that doesn't give you direct
3780 access to the underlying socket used.
3781
3782 Finally, test_support.HOST has been introduced, which should be used
3783 for the host argument of any relevant socket calls (i.e. bind and
3784 connect).

3792 suite to run in parallel without issue.

4058Core and builtins
4059-----------------
4060
Fred Drakea8ee94b2008-03-01 02:45:07 +00004061- Issue #2051: pyc and pyo files are no longer created with permission
Barry Warsaw52973612008-03-01 02:23:38 +00004062 644. The mode is now inherited from the py file.
Christian Heimes40346852008-02-23 17:52:07 +00004063
Georg Brandlad61bc82008-02-23 15:11:18 +00004064- Issue #2067: file.__exit__() now calls subclasses' close() method.
4065
4066- Patch #1759: Backport of PEP 3129 class decorators.
Christian Heimes5224d282008-02-23 15:01:05 +00004067
Vinay Sajipb7edfc42008-04-02 21:10:23 +00004068- Issue #1881: An internal parser limit has been increased. Also see
Facundo Batistafc2d0102008-02-23 12:01:13 +00004069 issue 215555 for a discussion.
4070
Eric Smitha73fbe72008-02-23 03:09:44 +00004071- Added the future_builtins module, which contains hex() and oct().
4072 These are the PEP 3127 version of these functions, designed to be
4073 compatible with the hex() and oct() builtins from Python 3.0. They
4074 differ slightly in their output formats from the existing, unchanged
4075 Python 2.6 builtins. The expected usage of the future_builtins
4076 module is:
4077 from future_builtins import hex, oct
4078
Eric Smith7ef40bf2008-02-20 23:34:22 +00004079- Issue #1600: Modifed PyOS_ascii_formatd to use at most 2 digit
4080 exponents for exponents with absolute value < 100. Follows C99
4081 standard. This is a change on Windows, which would use 3 digits.
4082 Also, added 'n' to the formats that PyOS_ascii_formatd understands,
4083 so that any alterations it does to the resulting string will be
4084 available in stringlib/formatter.h (for float.__format__).
4085
Eric Smith5a3c1352008-02-19 13:21:56 +00004086- Implemented PEP 3101, Advanced String Formatting. This adds a new
4087 builtin format(); a format() method for str and unicode; a
4088 __format__() method to object, str, unicode, int, long, float, and
4089 datetime; the class string.Formatter; and the C API
4090 PyObject_Format().
4091
Georg Brandl3ee81df2008-05-17 18:14:43 +00004092- Fixed several potential crashes, all caused by specially crafted
4093 __del__ methods exploiting objects in temporarily inconsistent
4094 state.
Amaury Forgeot d'Arc632fad32008-02-16 20:55:24 +00004095
Vinay Sajipb7edfc42008-04-02 21:10:23 +00004096- Issue #2115: Important speedup in setting __slot__ attributes. Also
Georg Brandl3ee81df2008-05-17 18:14:43 +00004097 prevent a possible crash: an Abstract Base Class would try to access
4098 a slot on a registered virtual subclass.
Amaury Forgeot d'Arc60d6c7f2008-02-15 21:22:45 +00004099
Georg Brandl3ee81df2008-05-17 18:14:43 +00004100- Fixed repr() and str() of complex numbers with infinity or nan as
4101 real or imaginary part.
Christian Heimes2f0da532008-02-15 06:57:08 +00004102
Georg Brandl3ee81df2008-05-17 18:14:43 +00004103- Clear all free lists during a gc.collect() of the highest generation
4104 in order to allow pymalloc to free more arenas. Python may give back
4105 memory to the OS earlier.
Christian Heimes3b718a72008-02-14 12:47:33 +00004106
Georg Brandl3ee81df2008-05-17 18:14:43 +00004107- Issue #2045: Fix an infinite recursion triggered when printing a
4108 subclass of collections.defaultdict, if its default_factory is set
4109 to a bound method.
Amaury Forgeot d'Arcb01aa432008-02-08 00:56:02 +00004110
Christian Heimesf75dbef2008-02-08 00:11:31 +00004111- Fixed a minor memory leak in dictobject.c. The content of the free
4112 list was not freed on interpreter shutdown.
4113
Georg Brandl21e99f42010-03-07 15:23:59 +00004114- Limit free list of method and built-in function objects to 256
Georg Brandl3ee81df2008-05-17 18:14:43 +00004115 entries each.
Christian Heimes6075a822008-02-06 12:44:34 +00004116
Georg Brandl3ee81df2008-05-17 18:14:43 +00004117- Patch #1953: Added ``sys._compact_freelists()`` and the C API
4118 functions ``PyInt_CompactFreeList`` and ``PyFloat_CompactFreeList``
Christian Heimes422051a2008-02-04 18:00:12 +00004119 to compact the internal free lists of pre-allocted ints and floats.
4120
Georg Brandl3ee81df2008-05-17 18:14:43 +00004121- Issue #1983: Fixed return type of fork(), fork1() and forkpty()
4122 calls. Python expected the return type int but the fork familie
4123 returns pi_t.
Christian Heimes951cc0f2008-01-31 23:08:23 +00004124
Georg Brandl3ee81df2008-05-17 18:14:43 +00004125- Issue #1678380: Fix a bug that identifies 0j and -0j when they
4126 appear in the same code unit.
Mark Dickinson105be772008-01-31 22:17:37 +00004127
Georg Brandl3ee81df2008-05-17 18:14:43 +00004128- Issue #2025: Add tuple.count() and tuple.index() methods to comply
4129 with the collections.Sequence API.
Raymond Hettinger5b07ebc2008-02-07 00:54:20 +00004130
Georg Brandl3ee81df2008-05-17 18:14:43 +00004131- Patch #1970 by Antoine Pitrou: Speedup unicode whitespace and
4132 linebreak detection
Christian Heimes4d4f2702008-01-30 11:32:37 +00004133
Georg Brandl3ee81df2008-05-17 18:14:43 +00004134- Added ``PyType_ClearCache()`` and ``sys._clear_type_cache`` to clear
4135 the internal lookup cache for ref leak tests.
Christian Heimes908caac2008-01-27 23:34:59 +00004136
Georg Brandl3ee81df2008-05-17 18:14:43 +00004137- Patch #1473257: generator objects gain a gi_code attribute. This is
4138 the same object as the func_code attribute of the function that
4139 produced the generator.
Georg Brandl0cdf9a32008-01-26 14:14:20 +00004140
Georg Brandl3ee81df2008-05-17 18:14:43 +00004141- Issue #1920: "while 0" statements were completely removed by the
4142 compiler, even in the presence of an "else" clause, which is
4143 supposed to be run when the condition is false. Now the compiler
4144 correctly emits bytecode for the "else" suite.
Amaury Forgeot d'Arc31eaafe2008-01-24 22:59:25 +00004145
Guido van Rossumeead05f2008-01-24 18:21:02 +00004146- A few crashers fixed: weakref_in_del.py (issue #1377858);
4147 loosing_dict_ref.py (issue #1303614, test67.py);
4148 borrowed_ref_[34].py (not in tracker).
4149
Vinay Sajipd7cf32e2008-01-24 12:43:33 +00004150- Issue #1069410: The "can't load dll" message box on Windows is
Christian Heimesb2302ba2008-01-23 17:15:06 +00004151 suppressed while an extension is loaded by calling SetErrorMode in
4152 dynload_win.c. The error is still reported properly.
4153
Georg Brandl3ee81df2008-05-17 18:14:43 +00004154- Issue #1915: Python compiles with --enable-unicode=no again. However
Christian Heimes082c9b02008-01-23 14:20:50 +00004155 several extension methods and modules do not work without unicode
4156 support.
4157
Georg Brandl26543b12008-01-21 18:36:51 +00004158- Issue #1882: when compiling code from a string, encoding cookies in the
4159 second line of code were not always recognized correctly.
4160
Georg Brandl14404b62008-01-19 19:27:05 +00004161- Issue #1679: "0x" was taken as a valid integer literal.
4162
Georg Brandl6caad7d2008-01-26 14:19:22 +00004163- Issue #1865: ``bytes`` as an alias for ``str`` and b"" as an alias "" were
Christian Heimes288e89a2008-01-18 18:24:07 +00004164 added.
4165
Christian Heimesc94e2b52008-01-14 04:13:37 +00004166- sys.float_info / PyFloat_GetInfo: The floating point information
4167 object was converted from a dict to a specialized structseq object.
4168
Georg Brandl3ee81df2008-05-17 18:14:43 +00004169- Patch #1816: Added sys.flags structseq. It exposes the status of
4170 most command line arguments and PYTHON* environment variables.
Christian Heimesf31b69f2008-01-14 03:42:48 +00004171
Georg Brandl3ee81df2008-05-17 18:14:43 +00004172- Objects/structseq.c: Implemented new structseq representation. The
4173 patch makes structseqs (e.g. the return value of os.stat) more
4174 readable.
Christian Heimes9c201962008-01-14 03:33:52 +00004175
Georg Brandl3ee81df2008-05-17 18:14:43 +00004176- Patch #1700288: added a type attribute cache that caches method
4177 accesses, resulting in speedups in heavily object-oriented code.
Amaury Forgeot d'Arce4c270c2008-01-14 00:29:41 +00004178
Neal Norwitz3fc15b82008-01-10 05:42:58 +00004179- Bug #1776: __import__() no longer accepts filenames on any platform.
4180 The first parameter to __import__() must be a valid module name.
Christian Heimes3403f152008-01-09 19:56:33 +00004181
Georg Brandlaed6c662008-01-07 17:25:53 +00004182- Patch #1668: renamed THREADDEBUG envvar to PYTHONTHREADDEBUG.
4183
Georg Brandl3ee81df2008-05-17 18:14:43 +00004184- Patch #602345: Add -B command line option, PYTHONDONTWRITEBYTECODE
4185 envvar and sys.dont_write_bytecode attribute. All these can be set
4186 to forbid Python to attempt to write compiled bytecode files.
Georg Brandl2da0fce2008-01-07 17:09:35 +00004187
Georg Brandl3ee81df2008-05-17 18:14:43 +00004188- Improve some exception messages when Windows fails to load an
4189 extension module. Now we get for example '%1 is not a valid Win32
4190 application' instead of 'error code 193'.
Amaury Forgeot d'Arce0b76952008-01-04 02:04:15 +00004191
Georg Brandl3ee81df2008-05-17 18:14:43 +00004192- Bug #1481296: Fixed long(float('nan')) != 0L.

Georg Brandl3ee81df2008-05-17 18:14:43 +00004194- Issue #1640: Added math.isinf(x), math.isnan(x) and math.copysign(x,
4195 y) functions.
Christian Heimese2ca4242008-01-03 20:23:15 +00004196
Christian Heimes0a8143f2007-12-18 23:22:54 +00004197- Issue #1635: Platform independent creation and representation of NaN
Georg Brandl3ee81df2008-05-17 18:14:43 +00004198 and INF. float("nan"), float("inf") and float("-inf") now work on
4199 every platform with IEEE 754 semantics.
Christian Heimes0a8143f2007-12-18 23:22:54 +00004200
Georg Brandl3ee81df2008-05-17 18:14:43 +00004201- Compiler now generates simpler and faster code for dictionary
4202 literals. The oparg for BUILD_MAP now indicates an estimated
4203 dictionary size. There is a new opcode, STORE_MAP, for adding
4204 entries to the dictionary.
Raymond Hettingerfd7ed402007-12-18 21:24:09 +00004205
Georg Brandl3ee81df2008-05-17 18:14:43 +00004206- Issue #1638: %zd configure test fails on Linux.

4212 is not found.
Skip Montanaro26015492007-12-08 15:33:24 +00004213
Andrew M. Kuchling395fe442007-12-05 13:27:20 +00004214- Issue #1553: An erroneous __length_hint__ can make list() raise a
Christian Heimes7cc1c6f2007-12-05 12:52:34 +00004215 SystemError.
4216
Nick Coghlanef01d822007-12-03 12:55:17 +00004217- PEP 366: Allow explicit relative imports when executing modules
4218 inside packages with the -m switch via a new module level
4219 __package__ attribute.
4220
Georg Brandl3ee81df2008-05-17 18:14:43 +00004221- Issue #1402: Fix a crash on exit, when another thread is still
4222 running, and if the deallocation of its frames somehow calls the
4223 PyGILState_Ensure() / PyGILState_Release() functions.
Amaury Forgeot d'Arcbe49a902007-11-30 20:37:22 +00004224

4234 file can now be directly executed by passing their name to the
4235 interpreter. The directory/zipfile is automatically inserted as the
4236 first entry in sys.path.
Nick Coghlan327a39b2007-11-18 11:56:28 +00004237
Georg Brandl3ee81df2008-05-17 18:14:43 +00004238- Issue #1265: Fix a problem with sys.settrace, if the tracing
4239 function uses a generator expression when at the same time the
4240 executed code is closing a paused generator.
Amaury Forgeot d'Arc0d75f092007-11-13 21:54:28 +00004241
Raymond Hettinger1760c8a2007-11-08 02:52:43 +00004242- sets and frozensets now have an isdisjoint() method.
4243
Raymond Hettinger3f8caa32007-10-24 01:28:33 +00004244- optimize the performance of builtin.sum().

Neal Norwitz44f326e2007-10-05 05:29:17 +00004246- Fix warnings found by the new version of the Coverity checker.
4247
Georg Brandl21e99f42010-03-07 15:23:59 +00004248- The enumerate() built-in function is no longer bounded to sequences
Georg Brandl3ee81df2008-05-17 18:14:43 +00004249 smaller than LONG_MAX. Formerly, it raised an OverflowError. Now,
4250 automatically shifts from ints to longs.
Raymond Hettinger8f669372007-10-03 21:18:11 +00004251
Georg Brandl3ee81df2008-05-17 18:14:43 +00004252- Issue #1686386: Tuple's tp_repr did not take into account the
4253 possibility of having a self-referential tuple, which is possible
4254 from C code. Nor did object's tp_str consider that a type's tp_str
4255 could do something that could lead to an inifinite recursion.
4256 Py_ReprEnter() and Py_EnterRecursiveCall(), respectively, fixed the
4257 issues.
Brett Cannon0b14f242007-09-30 19:45:10 +00004258
Georg Brandl3ee81df2008-05-17 18:14:43 +00004259- Issue #1164: It was possible to trigger deadlock when using the
4260 'print' statement to write to a file since the GIL was not released
4261 as needed. Now PyObject_Print() does the right thing along with
4262 various tp_print implementations of the built-in types and those in
4263 the collections module.
Brett Cannon01531592007-09-17 03:28:34 +00004264
Georg Brandl3ee81df2008-05-17 18:14:43 +00004265- Issue #1147: Exceptions were directly allowing string exceptions in
4266 their throw() method even though string exceptions no longer
4267 allowed.

Brett Cannon1e534b52007-09-07 04:18:30 +00004272- Issue #1202533: Fix infinite recursion calls triggered by calls to
Georg Brandl3ee81df2008-05-17 18:14:43 +00004273 PyObject_Call() never calling back out to Python code to trigger
4274 recursion depth updates/checks. Required the creation of a static
4275 RuntimeError instance in case normalizing an exception put the
4276 recursion check value past its limit. Fixes crashers
4277 infinite_rec_(1|2|4|5).py.
Brett Cannon1e534b52007-09-07 04:18:30 +00004278
Georg Brandl3ee81df2008-05-17 18:14:43 +00004279- Patch #1031213: Decode source line in SyntaxErrors back to its

4283 with %G.
4284
Georg Brandl3ee81df2008-05-17 18:14:43 +00004285- Prevent expandtabs() on string and unicode objects from causing a
4286 segfault when a large width is passed on 32-bit platforms.

Georg Brandla5ea6892007-06-01 11:33:33 +00004291
Neal Norwitz0ac60192007-05-27 04:08:54 +00004292- Add new attribute names for function objects. All the func_* become
Georg Brandl3ee81df2008-05-17 18:14:43 +00004293 __*__ attributes. (Some already existed, e.g., __doc__ and
4294 __name__.)
Neal Norwitz0ac60192007-05-27 04:08:54 +00004295
Neal Norwitz8b2bfbc2007-05-23 06:35:32 +00004296- Add -3 option to the interpreter to warn about features that are
4297 deprecated and will be changed/removed in Python 3.0.
4298
Georg Brandl2134e752007-05-21 20:34:16 +00004299- Patch #1686487: you can now pass any mapping after '**' in function
4300 calls.
4301
Collin Winter62903052007-05-18 23:11:24 +00004302- except clauses may now be spelled either "except E, target:" or
Georg Brandl3ee81df2008-05-17 18:14:43 +00004303 "except E as target:". This is to provide forwards compatibility
4304 with Python 3.0.
Collin Winter62903052007-05-18 23:11:24 +00004305
Brett Cannon229cee22007-05-05 01:34:02 +00004306- Deprecate BaseException.message as per PEP 352.
4307
Georg Brandl3ee81df2008-05-17 18:14:43 +00004308- Issue #1303614: don't expose object's __dict__ when the dict is
Georg Brandl21e99f42010-03-07 15:23:59 +00004309 inherited from a built-in base.
Armin Rigo9790a272007-05-02 19:23:31 +00004310
Vinay Sajip8549ce32007-05-06 17:53:37 +00004311- When __slots__ are set to a unicode string, make it work the same as
Neal Norwitzcbd9ee62007-04-14 05:25:50 +00004312 setting a plain string, ie don't expand to single letter identifiers.
4313
Raymond Hettinger13936692007-04-11 18:40:58 +00004314- Request #1191699: Slices can now be pickled.
4315
Raymond Hettinger4db5fe92007-04-12 04:10:00 +00004316- Request #1193128: str.translate() now allows a None argument for
4317 translations that only remove characters without re-mapping the
4318 remaining characters.
4319
Georg Brandl5cb76c12007-03-21 09:00:39 +00004320- Patch #1682205: a TypeError while unpacking an iterable is no longer
4321 masked by a generic one with the message "unpack non-sequence".
4322
Neal Norwitzaa754b72007-03-21 06:39:48 +00004323- Remove unused file Python/fmod.c.
4324
Guido van Rossum143b5642007-03-23 04:58:42 +00004325- Bug #1683368: The object.__init__() and object.__new__() methods are
4326 now stricter in rejecting excess arguments. The only time when
4327 either allows excess arguments is when it is not overridden and the
4328 other one is. For backwards compatibility, when both are
4329 overridden, it is a deprecation warning (for now; maybe a Py3k
Guido van Rossum234b1ff2007-03-23 19:39:01 +00004330 warning later). Also, type.__init__() insists on the same signature
4331 as supported by type.__new__().
Guido van Rossum143b5642007-03-23 04:58:42 +00004332
Georg Brandl3ee81df2008-05-17 18:14:43 +00004333- Patch #1675423: PyComplex_AsCComplex() now tries to convert an
4334 object to complex using its __complex__() method before falling back
4335 to the __float__() method. Therefore, the functions in the cmath
4336 module now can operate on objects that define a __complex__()
4337 method.
Georg Brandl2b869942007-03-17 16:08:45 +00004338
Georg Brandl3ee81df2008-05-17 18:14:43 +00004339- Patch #1623563: allow __class__ assignment for classes with
4340 __slots__. The old and the new class are still required to have the
4341 same slot names.
Žiga Seilnacht6f2d09c2007-03-16 11:59:38 +00004342
Georg Brandl3ee81df2008-05-17 18:14:43 +00004343- Patch #1642547: Fix an error/crash when encountering syntax errors

4347 ``object.__reduce_ex__()`` is called with an object that is faking
4348 its type.
Žiga Seilnacht20f43d32007-03-15 11:44:55 +00004349
Georg Brandl3ee81df2008-05-17 18:14:43 +00004350- Patch #1680015: Don't modify __slots__ tuple if it contains an
4351 unicode name.

Georg Brandl5240d742007-03-13 20:46:32 +00004353- Patch #1444529: the builtin compile() now accepts keyword arguments.
4354
Georg Brandl7b9c5552007-03-12 14:30:05 +00004355- Bug #1678647: write a newline after printing an exception in any
4356 case, even when converting the value to a string failed.
4357
Georg Brandl871f1bc2007-03-12 13:17:36 +00004358- The dir() function has been extended to call the __dir__() method on
Georg Brandl3ee81df2008-05-17 18:14:43 +00004359 its argument, if it exists. If not, it will work like before. This
4360 allows customizing the output of dir() in the presence of a
4361 __getattr__().
Georg Brandl871f1bc2007-03-12 13:17:36 +00004362
Collin Winter276887b2007-03-12 16:11:39 +00004363- Patch #922167: Python no longer segfaults when faced with infinitely
4364 self-recursive reload() calls (as reported by bug #742342).
4365

4370 parthensized forms. This means complex(repr(x)) now works instead of
4371 raising a ValueError.
Collin Wintere38051d2007-03-09 20:33:07 +00004372
Georg Brandlaa2321b2007-03-07 00:40:28 +00004373- Patch #703779: unset __file__ in __main__ after running a file. This
Georg Brandl3ee81df2008-05-17 18:14:43 +00004374 makes the filenames the warning module prints much more sensible
4375 when a PYTHONSTARTUP file is used.
Georg Brandlaa2321b2007-03-07 00:40:28 +00004376
Georg Brandl49aafc92007-03-07 00:34:46 +00004377- Variant of patch #697613: don't exit the interpreter on a SystemExit
4378 exception if the -i command line option or PYTHONINSPECT environment
Georg Brandl3ee81df2008-05-17 18:14:43 +00004379 variable is given, but break into the interactive interpreter just
4380 like on other exceptions or normal program exit.

Georg Brandl3ee81df2008-05-17 18:14:43 +00004385- Bug #1674503: close the file opened by execfile() in an error
4386 condition.
Georg Brandl098cd692007-03-06 12:17:50 +00004387
Georg Brandl0fca97a2007-03-05 22:28:08 +00004388- Patch #1674228: when assigning a slice (old-style), check for the
4389 sq_ass_slice instead of the sq_slice slot.
4390
Georg Brandl3ee81df2008-05-17 18:14:43 +00004391- When printing an unraisable error, don't print exceptions. before
4392 the name. This duplicates the behavior whening normally printing
4393 exceptions.
Neal Norwitz88516a62007-02-26 22:41:45 +00004394
Georg Brandl3ee81df2008-05-17 18:14:43 +00004395- Bug #1653736: Properly discard third argument to

Georg Brandl3ee81df2008-05-17 18:14:43 +00004401- Bug #1377858: Fix the segfaulting of the interpreter when an object
4402 created a weakref on itself during a __del__ call for new-style
4403 classes (classic classes still have the bug).
Brett Cannonf5bee302007-01-23 23:21:22 +00004404

4450
Armin Rigo7ccbca92006-10-04 12:17:45 +00004451- A number of places, including integer negation and absolute value,
4452 were fixed to not rely on undefined behaviour of the C compiler
4453 anymore.

5002 Python would crash instead of raising an error.
5003

5016
Georg Brandl3ee81df2008-05-17 18:14:43 +00005017- unittest now verifies more of its assumptions. In particular,
5018 TestCase and TestSuite subclasses (not instances) are no longer
5019 accepted in TestSuite.addTest(). This should cause no
5020 incompatibility since it never made sense with ordinary subclasses
5021 -- the failure just occurred later, with a more cumbersome
5022 exception.

5305 obtained from the TLS negotiation itself. Patch contributed by Bill
5306 Fenner.
Gregory P. Smith2b3ba582008-01-17 08:03:17 +00005307
Georg Brandl3ee81df2008-05-17 18:14:43 +00005308- Issue #1339: The smtplib.SMTP class has been refactored a bit such
Gregory P. Smithbde4ae42008-01-17 08:35:49 +00005309 that the SMTP.starttls() caller no longer needs to call ehlo()
5310 beforehand. SMTP.starttls() now raises an exception of the server
Georg Brandl3ee81df2008-05-17 18:14:43 +00005311 does not claim to support starttls. Adds the
5312 SMTP.ehlo_or_helo_if_needed() method. Patch contributed by Bill

5393 complex, tuple, list, dict, set, and frozenset. Formerly, it would
5394 silently miscode subclasses of those types. Now, it raises a

Georg Brandl3ee81df2008-05-17 18:14:43 +00005411 time so that opening a database previously created with the DB_DUP
5412 or DB_DUPSORT flag set will keep the proper behavior on subsequent
5413 opens. Specifically: dictionary assignment to a DB object will
5414 replace all values for a given key when the database allows
5415 duplicate values. DB users should use DB.put(k, v) when they want
5416 to store duplicates; not DB[k] = v.

5423 characters with ASCII value less than 32. Also, it correctly quotes
5424 dots only if they occur on a single line, as opposed to the previous
5425 behavior of quoting dots if they are the second character of any
5426 line.

5749-----
5750
Georg Brandl3ee81df2008-05-17 18:14:43 +00005751- Unified naming convention for free lists and their limits. All free
5752 lists in Object/ are named ``free_list``, the counter ``numfree``
5753 and the upper limit is a macro ``PyName_MAXFREELIST`` inside an
5754 #ifndef block.
Christian Heimes5b970ad2008-02-06 13:33:44 +00005755
Georg Brandl3ee81df2008-05-17 18:14:43 +00005756- ``PySet_Add()`` can now modify a newly created frozenset. Similarly
5757 to ``PyTuple_SetItem``, it can be used to populate a brand new
5758 frozenset; but it does not steal a reference to the added item.
Amaury Forgeot d'Arccab3d982008-02-03 22:51:43 +00005759
Vinay Sajipb7edfc42008-04-02 21:10:23 +00005760- Added ``PySet_Check()`` and ``PyFrozenSet_Check()`` to the set API.

Georg Brandl3ee81df2008-05-17 18:14:43 +00005762- Backport of PyUnicode_FromString(), _FromStringAndSize(), _Format
5763 and _FormatV from Python 3.0. Made PyLong_AsSsize_t and
5764 PyLong_FromSsize_t public functions.
Georg Brandl6caad7d2008-01-26 14:19:22 +00005765
5766- Patch #1720595: add T_BOOL to the range of structmember types.
5767
5768- Issue #1534: Added ``PyFloat_GetMax()``, ``PyFloat_GetMin()`` and
5769 ``PyFloat_GetInfo()`` to the float API.
5770
Georg Brandl3ee81df2008-05-17 18:14:43 +00005771- Issue #1521: On 64bit platforms, using PyArgs_ParseTuple with the t#
5772 of w# format code incorrectly truncated the length to an int, even
5773 when PY_SSIZE_T_CLEAN is set. The str.decode method used to return
5774 incorrect results with huge strings.
Georg Brandl6caad7d2008-01-26 14:19:22 +00005775
Georg Brandl3ee81df2008-05-17 18:14:43 +00005776- Issue #1629: Renamed Py_Size, Py_Type and Py_Refcnt to Py_SIZE,
5777 Py_TYPE and Py_REFCNT.

Georg Brandl3ee81df2008-05-17 18:14:43 +00005779- PEP 3123: Provide forward compatibility with Python 3.0, while
5780 keeping backwards compatibility. Add Py_Refcnt, Py_Type, Py_Size,
5781 and PyVarObject_HEAD_INIT.
Georg Brandl6caad7d2008-01-26 14:19:22 +00005782
Georg Brandl3ee81df2008-05-17 18:14:43 +00005783- Py_ssize_t fields work in structmember when HAVE_LONG_LONG is not
5784 defined.
Georg Brandl6caad7d2008-01-26 14:19:22 +00005785
5786- Patch #1733960: Allow T_LONGLONG to accept ints.
5787
5788- T_PYSSIZET can now be used in PyMemberDef lists for Py_ssize_t members.
5789
Christian Heimes000a0742008-01-03 22:16:32 +00005790- Added a new API function ``PyImport_ImportModuleNoBlock``.

5793
5794- Fix some leftovers from the conversion from int to Py_ssize_t
5795 (relevant to strings and sequences of more than 2**31 items).
5796
5797- Make _PyGILState_NoteThreadState() static, it was not used anywhere
5798 outside of pystate.c and should not be necessary.
5799
Georg Brandl3ee81df2008-05-17 18:14:43 +00005800- ``PyImport_Import`` and ``PyImport_ImportModule`` now always do
5801 absolute imports. In earlier versions they might have used relative
5802 imports under some conditions.
Christian Heimes000a0742008-01-03 22:16:32 +00005803
Georg Brandl3ee81df2008-05-17 18:14:43 +00005804- Added case insensitive comparison methods ``PyOS_stricmp(char*,
5805 char*)`` and ``PyOS_strnicmp(char*, char*, Py_ssize_t)``.
Christian Heimes000a0742008-01-03 22:16:32 +00005806
Georg Brandl3ee81df2008-05-17 18:14:43 +00005807- Bug #1542693: remove semi-colon at end of PyImport_ImportModuleEx

5813
Georg Brandl3ee81df2008-05-17 18:14:43 +00005814- Patch #1706: Drop support for Win9x, WinME and NT4. Python now
5815 requires Windows 2000 or greater. The _WINVER and NTDDI_VERSION
5816 macros are set to Win2k for x86/32bit builds and WinXP for AMD64
5817 builds.
Christian Heimes95d64472008-02-09 19:55:22 +00005818
Georg Brandl3ee81df2008-05-17 18:14:43 +00005819- Conditionalize definition of _CRT_SECURE_NO_DEPRECATE and

Brett Cannon791d56f2007-05-31 19:40:42 +00005830- buildtools now raises a DeprecationWarning.
5831
Georg Brandl3ee81df2008-05-17 18:14:43 +00005832- Removed the macfs module. It had been deprecated since Python 2.5.
5833 This lead to the deprecation of macostools.touched() as it relied
5834 solely on macfs and was a no-op under OS X.
