Antoine Pitroua57df2c2010-03-31 21:32:15 +000015- Issue #8268: Old-style classes (not just instances) now support weak
16 references.
17
Victor Stinner6cbf90f2010-03-25 00:21:53 +000018- Issue #8211: Save/restore CFLAGS around AC_PROG_CC in configure.in, compiler
19 optimizations are disabled when --with-pydebug is used.
20
Victor Stinnerc7790ed2010-03-22 12:36:28 +000021- Issue #1583863: An unicode subclass can now override the __unicode__ method

Benjamin Peterson96545892010-03-21 20:21:00 +000023- Issue #6474: Make error message from passing an inadequate number of keyword
24 arguments to a function correct.
25
Benjamin Peterson0dee9c12010-03-17 20:41:42 +000026- Issue #8164: Don't allow lambda functions to have a docstring.
27
Victor Stinner66644262010-03-10 22:30:19 +000028- Issue #3137: Don't ignore errors at startup, especially a keyboard interrupt
Georg Brandlba83f822010-03-14 09:50:54 +000029 (SIGINT). If an error occurs while importing the site module, the error is
30 printed and Python exits. Initialize the GIL before importing the site
Victor Stinner66644262010-03-10 22:30:19 +000031 module.

Mark Dickinsone096e822010-04-02 10:17:07 +000038- Issue #7279: Comparisons involving a Decimal signaling NaN now
39 signal InvalidOperation instead of returning False. (Comparisons
Mark Dickinsonf3eeca12010-04-02 10:35:12 +000040 involving a quiet NaN are unchanged.) Also, Decimal quiet NaNs
41 are now hashable; Decimal signaling NaNs remain unhashable.
Mark Dickinsone096e822010-04-02 10:17:07 +000042
Mark Dickinson99d80962010-04-02 08:53:22 +000043- Issue #2531: Comparison operations between floats and Decimal
44 instances now return a result based on the numeric values of the
45 operands; previously they returned an arbitrary result based on
46 the relative ordering of id(float) and id(Decimal).
47
Barry Warsawf7f2d6f2010-03-31 21:07:16 +000048- Issue #8233: When run as a script, py_compile.py optionally takes a single
49 argument `-` which tells it to read files to compile from stdin. Each line
50 is read on demand and the named file is compiled immediately. (Original
51 patch by Piotr Ożarowski).
52
53- Issue #3135: Add inspect.getcallargs, which binds arguments to a function
54 like a normal call.
Benjamin Peterson7e213252010-03-30 17:58:13 +000055
Florent Xicluna58b65662010-03-30 16:29:03 +000056- Backwards incompatible change: Unicode codepoints line tabulation (0x0B) and
57 form feed (0x0C) are now considered linebreaks, as specified in Unicode
58 Standard Annex #14. See issue #7643.
Florent Xicluna22b24382010-03-30 08:24:06 +000059 http://www.unicode.org/reports/tr14/
60
Mark Dickinson9588d992010-03-27 11:14:37 +000061- Comparisons using one of <, <=, >, >= between a complex instance and
62 a Fractions instance now raise TypeError instead of returning
63 True/False. This makes Fraction <=> complex comparisons consistent with
64 int <=> complex, float <=> complex, and complex <=> complex comparisons.
65
Michael Foorde6410c52010-03-29 20:04:23 +000066- Addition of ``WeakSet`` to the ``weakref`` module.

71 running from the build directory (POSIX only).
72
Florent Xiclunae1f4c922010-03-22 22:45:50 +000073- Issue #7667: Fix doctest failures with non-ASCII paths.
74
Antoine Pitrou513d9ae2010-03-22 19:59:46 +000075- Issue #7512: shutil.copystat() could raise an OSError when the filesystem
76 didn't support chflags() (for example ZFS under FreeBSD). The error is
77 now silenced.
78
Florent Xicluna9e7a4c92010-03-22 16:07:38 +000079- Issue #7703: ctypes supports both buffer() and memoryview(). The former is
80 deprecated.
81
R. David Murrayc9d1a782010-03-22 15:55:09 +000082- Issue #7860: platform.uname now reports the correct 'machine' type
83 when Python is running in WOW64 mode on 64 bit Windows.
84
Vinay Sajip804899b2010-03-22 15:29:01 +000085- logging: Added getChild utility method to Logger and added isEnabledFor
86 method to LoggerAdapter.
87
Vinay Sajip31e928e2010-03-22 13:02:28 +000088- Issue #8201: logging: Handle situation of non-ASCII and Unicode
89 logger names existing at the same time, causing a Unicode error
90 when configuration code attempted to sort the existing loggers.
91
Vinay Sajip3017a7b2010-03-22 12:33:08 +000092- Issue #8200: logging: Handle errors when multiprocessing is not
93 fully loaded when logging occurs.
94
Antoine Pitroueee91cd2010-03-26 19:27:16 +000095- Issue #3890, #8222: Fix recv() and recv_into() on non-blocking SSL sockets.
96 Also, enable the SSL_MODE_AUTO_RETRY flag on SSL sockets, so that blocking
97 reads and writes are always retried by OpenSSL itself.
Antoine Pitrou448da712010-03-21 19:33:38 +000098
Florent Xiclunacf82fa62010-03-21 12:27:20 +000099- Issue #8179: Fix macpath.realpath() on a non-existing path.

111
Matthias Klose358e7ff2010-03-15 13:42:23 +0000112- Issue #7356: ctypes.util: Make parsing of ldconfig output independent of
113 the locale.
114
Georg Brandlba83f822010-03-14 09:50:54 +0000115- Issue #7774: Set sys.executable to an empty string if ``argv[0]`` has been
Victor Stinner75227342010-03-12 14:30:26 +0000116 set to an non existent program name and Python is unable to retrieve the real
Georg Brandlba83f822010-03-14 09:50:54 +0000117 program name.
Victor Stinner75227342010-03-12 14:30:26 +0000118
Vinay Sajipecfa08f2010-03-12 09:16:10 +0000119- Issue #8117: logging: Improved algorithm for computing initial rollover time
Georg Brandlba83f822010-03-14 09:50:54 +0000120 for ``TimedRotatingFileHandler`` by using the modification time of an
121 existing log file to compute the next rollover time. If the log file does
122 not exist, the current time is used as the basis for the computation.
Vinay Sajip9098ee42010-03-12 06:01:21 +0000123
Georg Brandlba83f822010-03-14 09:50:54 +0000124- Issue #6472: The ``xml.etree`` package is updated to ElementTree 1.3. The

Florent Xicluna47627d52010-03-08 15:20:28 +0000130 classes.
131
Georg Brandlba83f822010-03-14 09:50:54 +0000132- Issue #7143: email: ``get_payload()`` used to strip any trailing newline from
133 a base64 transfer-encoded payload *after* decoding it; it no longer does.
134 This is a behavior change, so email's minor version number is now bumped, to
135 version 4.0.2, for the 2.7 release.
R. David Murray4617e502010-03-08 02:04:06 +0000136

Matthias Klosee9fbf2b2010-03-19 14:45:06 +0000143- Issue #1039, #8154: Fix os.execlp() crash with missing 2nd argument.
144
Jesus Cea6557aac2010-03-22 14:22:26 +0000145- Issue #8156: bsddb module updated to version 4.8.4.
146 http://www.jcea.es/programacion/pybsddb.htm#bsddb3-4.8.4.
147 This update drops support for Berkeley DB 4.0, and adds support for 4.8.
Matthias Klose54cc5392010-03-15 12:46:18 +0000148
Matthias Klose817acef2010-03-15 00:02:36 +0000149- Issue #8142: Update libffi to the 3.0.9 release.
150
Georg Brandlba83f822010-03-14 09:50:54 +0000151- Issue #1530559: When passing a non-integer argument to struct.pack with *any*
152 integer format code (one of 'bBhHiIlLqQ'), struct.pack attempts to use the
153 argument's __int__ method to convert to an integer before packing. It also
154 produces a DeprecationWarning in this case. (In Python 2.6, the behaviour
155 was inconsistent: __int__ was used for some integer codes but not for others,
156 and the set of integer codes for which it was used differed between native
157 packing and standard packing.)

Antoine Pitrou76c86492010-04-01 16:42:11 +0000185- Issue #8276: PyEval_CallObject() is now only available in macro form. The
186 function declaration, which was kept for backwards compatibility reasons,
187 is now removed (the macro was introduced in 1997!).
188
Larry Hastings402b73f2010-03-25 00:54:54 +0000189- Issue #7992: A replacement PyCObject API, PyCapsule, has been backported
Larry Hastings5ac006d2010-04-02 11:01:35 +0000190 from Python 3.1. All existing Python CObjects in the main distribution
191 have been converted to capsules. To address backwards-compatibility
192 concerns, PyCObject_AsVoidPtr() was changed to understand capsules.

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

Antoine Pitrouf3fa0742010-01-31 22:26:04 +0000437- Issue #6939: Fix file I/O objects in the `io` module to keep the original
Georg Brandlba83f822010-03-14 09:50:54 +0000438 file position when calling `truncate()`. It would previously change the file
439 position to the given argument, which goes against the tradition of
Antoine Pitrouf3fa0742010-01-31 22:26:04 +0000440 ftruncate() and other truncation APIs. Patch by Pascal Chambon.

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

Georg Brandlba83f822010-03-14 09:50:54 +0000459- Issue #7748: Since unicode values are supported for some metadata options in

461 encoded string for them. This ensures that the upload and register commands
462 send the correct values to PyPI without any error.

536Core and Builtins
537-----------------
538
Georg Brandlba83f822010-03-14 09:50:54 +0000539- The ``__complex__()`` method is now looked up on the class of instances to
540 make it consistent with other special methods.
Benjamin Petersonecdae192010-01-04 00:43:01 +0000541
Antoine Pitrou5b7139a2010-01-02 21:12:58 +0000542- Issue #7462: Implement the stringlib fast search algorithm for the `rfind`,
543 `rindex`, `rsplit` and `rpartition` methods. Patch by Florent Xicluna.
544
Mark Dickinson1b34d252010-01-01 17:27:30 +0000545- Issue #5080: A number of functions and methods previously produced a
Georg Brandlba83f822010-03-14 09:50:54 +0000546 DeprecationWarning when passed a float argument where an integer was expected.
547 These functions and methods now raise TypeError instead. The majority of the
548 effects of this change are in the extension modules, but some core functions
549 and methods are affected: notably the 'chr', 'range' and 'xrange' builtins,
550 and many unicode/str methods.
Mark Dickinson1b34d252010-01-01 17:27:30 +0000551

Amaury Forgeot d'Arc8645a5c2009-12-29 22:03:38 +0000560- Issue #7413: Passing '\0' as the separator to datetime.datetime.isoformat()
561 used to drop the time part of the result.
562
Georg Brandlba83f822010-03-14 09:50:54 +0000563- Issue #1811: Improve accuracy and cross-platform consistency for true division
564 of integers: the result of a/b is now correctly rounded for ints a and b (at
565 least on IEEE 754 platforms), and in particular does not depend on the
566 internal representation of a long.
Mark Dickinson46572832009-12-27 14:55:57 +0000567
Georg Brandlba83f822010-03-14 09:50:54 +0000568- Issue #6108: ``unicode(exception)`` and ``str(exception)`` should return the
569 same message when only ``__str__()`` (and not ``__unicode__()``) is overridden
570 in the subclass.
Ezio Melottif84caf42009-12-24 22:25:17 +0000571
Georg Brandlba83f822010-03-14 09:50:54 +0000572- Issue #6834: Replace the implementation for the 'python' and 'pythonw'
Ronald Oussoren92919a62009-12-24 13:30:58 +0000573 executables on OSX.
574
Georg Brandlba83f822010-03-14 09:50:54 +0000575 These executables now work properly with the arch(1) command: ``arch -ppc
576 python`` will start a universal binary version of python in PPC mode (unlike
577 previous releases).
Ronald Oussoren92919a62009-12-24 13:30:58 +0000578
Georg Brandlba83f822010-03-14 09:50:54 +0000579- Issue #1680159: Unicode coercion during an 'in' operation no longer masks the
580 underlying error when the coercion fails for the left hand operand.

Georg Brandlba83f822010-03-14 09:50:54 +0000591- Issue #6963: Added "maxtasksperchild" argument to ``multiprocessing.Pool``,
592 allowing for a maximum number of tasks within the pool to be completed by the
593 worker before that worker is terminated, and a new one created to replace it.

Georg Brandlba83f822010-03-14 09:50:54 +0000600 renaming of `cPickle` to `pickle`. The warning was annoying since there's no

Ezio Melotti569e61f2009-12-30 06:14:51 +0000621 Initial patch by Brian Curtin.
622
Georg Brandlba83f822010-03-14 09:50:54 +0000623- Distutils now correctly identifies the build architecture as "x86_64" when

Benjamin Petersonddd392c2009-12-13 19:19:07 +0000636- Issue #7349: Make methods of file objects in the io module accept None as an
637 argument where file-like objects (ie StringIO and BytesIO) accept them to mean
638 the same as passing no argument.
639
Georg Brandlba83f822010-03-14 09:50:54 +0000640- Issue #7348: ``StringIO.StringIO.readline(-1)`` now acts as if it got no

Georg Brandlba83f822010-03-14 09:50:54 +0000715- Issue #3382: 'F' formatting for float and complex now convert the result to
716 upper case. This only affects 'inf' and 'nan', since 'f' no longer converts
717 to 'g' for large values.
Amaury Forgeot d'Arcd7288712009-12-01 21:51:04 +0000718
Georg Brandlba83f822010-03-14 09:50:54 +0000719- Remove switch from "%f" formatting to "%g" formatting for floats larger than
720 1e50 in absolute value.
Mark Dickinson9dd5e162009-11-23 20:54:09 +0000721
Georg Brandlba83f822010-03-14 09:50:54 +0000722- Remove restrictions on precision when formatting floats. E.g., "%.120g" %
723 1e-100 used to raise OverflowError, but now gives the requested 120
724 significant digits instead.

Ronald Oussoren315cd0c2009-11-19 16:25:21 +0000732
Georg Brandlba83f822010-03-14 09:50:54 +0000733- Issue #7117: ``repr(x)`` for a float x returns a result based on the shortest
734 decimal string that's guaranteed to round back to x under correct rounding
735 (with round-half-to-even rounding mode). Previously it gave a string based on
736 rounding x to 17 decimal digits. repr(x) for a complex number behaves
737 similarly. On platforms where the correctly-rounded strtod and dtoa code is
738 not supported (see below), repr is unchanged.
Mark Dickinsonb678de82009-11-19 18:41:49 +0000739
Georg Brandlba83f822010-03-14 09:50:54 +0000740- Issue #7117: On almost all platforms: float-to-string and string-to-float
741 conversions within Python are now correctly rounded. Places these conversions
742 occur include: str for floats and complex numbers; the float and complex
743 constructors; old-style and new-style numeric formatting; serialization and
744 deserialization of floats and complex numbers using marshal, pickle and json;
745 parsing of float and imaginary literals in Python code; Decimal-to-float
746 conversion.
Mark Dickinsonb678de82009-11-19 18:41:49 +0000747
Georg Brandlba83f822010-03-14 09:50:54 +0000748 The conversions use a Python-adapted version of David Gay's well-known dtoa.c,
749 providing correctly-rounded strtod and dtoa C functions. This code is
750 supported on Windows, and on Unix-like platforms using gcc, icc or suncc as
751 the C compiler. There may be a small number of platforms on which correct
752 operation of this code cannot be guaranteed, so the code is not used: notably,
753 this applies to platforms where the C double format is not IEEE 754 binary64,
754 and to platforms on x86 hardware where the x87 FPU is set to 64-bit precision
755 and Python's configure script is unable to determine how to change the FPU
756 precision. On these platforms conversions use the platform strtod and dtoa,

Georg Brandlba83f822010-03-14 09:50:54 +0000759- Issue #7117: Backport round implementation from Python 3.x. ``round()`` now
760 uses the correctly-rounded string <-> float conversions described above (when
761 available), and so produces correctly rounded results that will display nicely
762 under the float repr. There are two related small changes: (1) round now
763 accepts any class with an ``__index__()`` method for its second argument (but
764 no longer accepts floats for the second argument), and (2) an excessively
765 large second integer argument (e.g., ``round(1.234, 10**100)``) no longer
766 raises an exception.

1145 this code path is really executed because I cannot move to such directory on

Amaury Forgeot d'Arc05e34492008-09-10 22:04:45 +00002549- Issue #3743: In a few places, PY_FORMAT_SIZE_T was incorrectly used with
2550 PyString_FromFormat or PyErr_Format to display size_t values. The macro
2551 PY_FORMAT_SIZE_T is designed to select the correct format for the OS
2552 ``printf`` function, whereas PyString_FromFormat has an independent
2553 implementation and uses "%zd" on all platforms for size_t values.
2554 This makes a difference on win64, where ``printf`` needs "%Id" to display
2555 64bit values.

2650 warnings.catch_warnings() along with some API cleanup. Expanding the tests
2651 for catch_warnings() also led to an improvement in the raising of a
2652 DeprecationWarning related to warnings.warn_explicit().
2653
Benjamin Peterson973e6c22008-09-01 23:12:58 +00002654- The deprecation warnings for the old camelCase threading API were removed.

2676
Amaury Forgeot d'Arc293924b2008-09-02 23:19:56 +00002677- Issue #2975: When compiling several extension modules with Visual Studio 2008
2678 from the same python interpreter, some environment variables would grow
2679 without limit.
2680
Benjamin Peterson37346b22008-08-23 20:27:43 +00002681- Issue #3643: Added a few more checks to _testcapi to prevent segfaults by

Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00002718What's New in Python 2.6 beta 3?
2719================================
2720
Barry Warsaw07a4a382008-08-21 01:15:08 +00002721*Release date: 20-Aug-2008*
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00002722
2723Core and Builtins
2724-----------------
2725
Guido van Rossumf8402962008-08-20 15:01:50 +00002726- Issue #1878: Remove Py_TPFLAGS_HAVE_VERSION_TAG from
2727 Py_TPFLAGS_DEFAULT when not building the core. This means 3rd party
2728 extensions do not automatically benefit from the class attribute
2729 cache; they will have to explicitly add Py_TPFLAGS_HAVE_VERSION_TAG
2730 to their tp_flags field if they care. This is a backwards
2731 compatibility feature; in 3.0, all types will use the cache by
2732 default.
2733
Benjamin Petersonf647dc12008-08-20 01:27:30 +00002734- Keyword arguments can now follow starred arguments. (``f(a, *args,
2735 keyword=23)`` is now valid syntax.)
2736
Thomas Heller0ad5ae02008-08-19 19:25:04 +00002737- ctypes function pointers that are COM methods have a boolean True
2738 value again.
2739
Martin v. Löwisf91d46a2008-08-12 14:49:50 +00002740- Issue #3139: Make buffer-interface thread-safe wrt. PyArg_ParseTuple,
2741 by denying s# to parse objects that have a releasebuffer procedure,
2742 and introducing s*.
2743
Georg Brandl1e13ea92008-08-11 09:07:59 +00002744- Issue #3537: Fix an assertion failure when an empty but presized dict
2745 object was stored in the freelist.
2746
Mark Dickinsonb6467572008-08-04 21:30:09 +00002747- Issue #1481296: Make long(float('nan')) and int(float('nan')) raise
2748 ValueError consistently across platforms.
2749
Amaury Forgeot d'Arc39fd6722008-07-31 21:28:03 +00002750- Issue #3479: On platforms where sizeof(int) is smaller than sizeof(long)
2751 (64bit Unix, for example), unichr() would truncate its argument and return
2752 u'\x00' for unichr(2**32). Now it properly raises an OverflowError.
2753
Neal Norwitze7d8be82008-07-31 17:17:14 +00002754- Apply security patches from Apple.
2755
Amaury Forgeot d'Arc246daed2008-07-31 00:42:16 +00002756- Issue #2542: Now that issubclass() may call arbitrary code, ensure that
2757 PyErr_ExceptionMatches returns 0 when an exception occurs there.
2758
Antoine Pitrou92f82162008-07-25 22:22:08 +00002759- Issue #1819: function calls with several named parameters are now on
2760 average 35% faster (as measured by pybench).
2761
Amaury Forgeot d'Arce4921fe2008-07-21 22:00:38 +00002762- Issue #2378: An unexpected UnboundLocalError or NameError could appear when
2763 the python debugger steps into a class statement: the free variables (local
2764 variables defined in an outer scope) would be deleted from the outer scope.
2765
Gregory P. Smith0470bab2008-07-22 04:46:32 +00002766- Issue #2620: Overflow checking when allocating or reallocating memory
2767 was not always being done properly in some python types and extension
2768 modules. PyMem_MALLOC, PyMem_REALLOC, PyMem_NEW and PyMem_RESIZE have
2769 all been updated to perform better checks and places in the code that
2770 would previously leak memory on the error path when such an allocation
2771 failed have been fixed.
2772
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00002773Library
2774-------
2775

2777
Benjamin Petersone977ad42008-08-20 01:42:01 +00002778- The methods ``is_in_tuple()``, ``is_vararg()``, and ``is_keywordarg()`` of
2779 symtable.Symbol have been deprecated for removal in 3.0 and the next release.
2780
Amaury Forgeot d'Arc351ffb82008-08-18 19:23:47 +00002781- Issue #2234: distutils failed for some versions of the cygwin compiler. The
2782 version reported by these tools does not necessarily follow the python
2783 version numbering scheme, so the module is less strict when parsing it.
2784
Nick Coghlanf70385a2008-08-18 12:42:46 +00002785- Issue #2235: Added Py3k warnings for types which will become unhashable
2786 under the stricter __hash__ inheritance rules in 3.0. Several types
2787 which did not meet the rules for hash invariants and were already
2788 unhashable in 3.0 have now been explicitly flagged as unhashable in
2789 2.6 as well (collections.Mapping, collections.Set, unittest.TestSuite,
2790 xml.dom.minidom.NamedNodeMap, numbers.Number, UserList.UserList)
2791
Brett Cannon88f801d2008-08-18 00:46:22 +00002792- Update __all__ for cookielib, csv, os, urllib2, and weakref to include things
2793 imported into the module but exposed as part of the module's API.

2800
Hirokazu Yamamoto41a81eb2008-08-17 13:10:46 +00002801- Issue #3575: Incremental decoder's decode function now takes bytearray
2802 by using 's*' instead of 't#'.
2803
Mark Dickinson3e4caeb2009-02-21 20:27:01 +00002804- Issue #2222: Fixed reference leak when occurred os.rename()
Hirokazu Yamamoto7f30a682008-08-17 09:46:56 +00002805 fails unicode conversion on 2nd parameter. (windows only)
2806
Facundo Batista94f243a2008-08-17 03:38:39 +00002807- Issue 2464. urllib2 now supports a malformation in the URL received
2808 in a redirect.
2809
Brett Cannonabe423e2008-08-16 21:47:07 +00002810- Silence the DeprecationWarning raised when importing mimetools in
Brett Cannon721b1452008-08-16 22:00:27 +00002811 BaseHTTPServer, cgi (and rfc822), httplib.
Brett Cannonabe423e2008-08-16 21:47:07 +00002812
Facundo Batistaeb90b782008-08-16 14:44:07 +00002813- Issue #2776: fixed small issue when handling an URL with double slash
2814 after a 302 response in the case of not going through a proxy.
2815
Antoine Pitroub90a8be2008-08-15 21:03:21 +00002816- Issue #2676: in the email package, content-type parsing was hanging on
2817 pathological input because of quadratic or exponential behaviour of a
2818 regular expression.
2819
Antoine Pitrou11ec65d2008-08-14 21:04:30 +00002820- Issue #3476: binary buffered reading through the new "io" library is now
2821 thread-safe.
2822
Brett Cannonbf3157b2008-08-14 05:00:03 +00002823- Silence the DeprecationWarning of rfc822 when it is imported by mimetools
2824 since mimetools itself is deprecated. Because modules are cached, all
2825 subsequent imports of rfc822 will not raise a visible DeprecationWarning.
2826
Antoine Pitrou9fcd4b32008-08-11 17:21:36 +00002827- Issue #3134: shutil referenced undefined WindowsError symbol.
2828
Robert Schuppenies14646332008-08-10 11:01:53 +00002829- Issue #1342811: Fix leak in Tkinter.Menu.delete. Commands associated to
2830 menu entries were not deleted.
2831
Brett Cannon83e81842008-08-09 23:30:55 +00002832- Copied the implementation of reduce() to _functools.reduce() to have a
2833 version that did not raise a DeprecationWarning under -3.
2834
Antoine Pitrou76b8bee2008-08-09 17:27:23 +00002835- Issue #3205: When iterating over a BZ2File fails allocating memory, raise
2836 a MemoryError rather than silently stop the iteration.
2837
Guido van Rossum59ce9012008-08-09 14:55:34 +00002838- Issue #3487: sre "bytecode" validator. Passing invalid "re-bytecode"
2839 to _sre.compile() will now be rejected. This should not affect anybody
2840 since the re.compile() function never generates invalid re-bytecode.
2841
Skip Montanaroa032bf42008-08-08 22:52:51 +00002842- Issue #3436: Make csv.DictReader's fieldnames attribute a property so that

2847 the reload() built-in has been removed.
2848
Brett Cannon7e30b672008-08-04 21:52:25 +00002849- Changed code in the following modules/packages to remove warnings raised
Brett Cannonc1b76e42008-08-09 23:06:16 +00002850 while running under the ``-3`` flag: aifc, asynchat, asyncore, bdb, bsddb,

Antoine Pitroude781a42008-08-09 12:43:23 +00002861 asking for a specific length. This problem only affected files opened
2862 using the new "io" module, not the built-in open() function.

2889 mode 0600 rather than 000 under Unix.
2890
Gregory P. Smitha36f8fe2008-08-04 00:13:29 +00002891- Issue #1857: subprocess.Popen.poll gained an additional _deadstate keyword

Eric Smitha5fa5a22008-07-16 00:11:49 +00002927- Issue #3083: Add alternate (#) formatting for bin, oct, hex output
2928 for str.format(). This adds the prefix 0b, 0o, or 0x, respectively.
2929
Mark Dickinson7103aa42008-07-15 19:08:33 +00002930- Issue #3008: the float type has a new instance method 'float.hex'
2931 and a new class method 'float.fromhex' to convert floating-point
2932 numbers to and from hexadecimal strings, respectively.
2933
Nick Coghlan6d6bd442008-07-15 15:40:22 +00002934- Issue #2235: __hash__ is once again inherited by default. To allow
2935 collections.Hashable to remain meaningful in the presence of the
2936 default hash implementation (object.__hash__), it is now possible
2937 to explicit block inheritance of hash by setting __hash__=None at
2938 the Python level, or tp_hash=PyObject_HashNotImplemented at the C
2939 level.
2940
Nick Coghlanb028f502008-07-13 14:52:36 +00002941- Issue #3221: Issue a RuntimeWarning instead of raising SystemError if
2942 the parent module cannot be found while performing an absolute import.
2943 This means that an incorrectly defined __package__ attribute will
2944 now only prevent relative imports in that module rather than causing
2945 all imports from that module to fail.
2946
Nick Coghlan14ff9942008-07-08 14:21:42 +00002947- Issue #2517: Allow unicode messages in Exceptions again by correctly

2956 threading.local: the first member set by a thread could be saved in
2957 another thread's dictionary.
2958
Mark Dickinson1ec2fcd2008-06-20 14:53:43 +00002959- Issue #3004: Minor change to slice.indices(): the start and stop
2960 arguments are now treated identically, making the behaviour easier
2961 to describe and understand. For example, slice(None, -10,
2962 1).indices(9) now returns (0, 0, 1) instead of (0, -1, 1), and
2963 slice(None, 10, -1).indices(10) returns (9, 9, -1) instead of (9,
2964 10, -1).
2965
Georg Brandl278fc502008-07-19 12:46:12 +00002966- Issue #3219: Calling a function with repeated keyword arguments,
2967 f(a=2, a=23), would not cause a syntax error. This was a regression
2968 from 2.4 caused by the switch to the new compiler.
Benjamin Peterson175e4d92008-07-01 19:34:52 +00002969
Georg Brandl278fc502008-07-19 12:46:12 +00002970- Issue #2862: Make int and float freelist management consistent with
2971 other freelists. Changes their CompactFreeList apis into
2972 ClearFreeList apis and calls them via gc.collect().

2978 api functions without holding the GIL, which could lead to a fatal
2979 error when they failed.
2980
Martin v. Löwisaabf4042008-08-02 07:20:25 +00002981- Issue #799428: Fix Tkinter.Misc._nametowidget to unwrap Tcl command objects.

Amaury Forgeot d'Arc0f7cddc2008-07-06 21:34:39 +00003006- Issue #839496: SimpleHTTPServer used to open text files in text mode. This is
3007 both unnecessary (HTTP allows text content to be sent in several forms) and
Andrew M. Kuchlingcc3f2b12008-07-10 14:43:31 +00003008 wrong because the actual transmitted size could differ from the
Amaury Forgeot d'Arc0f7cddc2008-07-06 21:34:39 +00003009 content-length. The problem had been corrected in the 2.4 branch, but never

3485 not called by default for backwards-compatibility reasons. Setting
3486 ``warnings.showwarning()`` to an implementation that lacks support
3487 for the ``line`` argument will raise a DeprecationWarning.

Georg Brandl3ee81df2008-05-17 18:14:43 +00003550- Issue #2550: The approach used by client/server code for obtaining
3551 ports to listen on in network-oriented tests has been refined in an
3552 effort to facilitate running multiple instances of the entire
3553 regression test suite in parallel without issue.
3554 test_support.bind_port() has been fixed such that it will always
3555 return a unique port -- which wasn't always the case with the
3556 previous implementation, especially if socket options had been set
3557 that affected address reuse (i.e. SO_REUSEADDR, SO_REUSEPORT). The
3558 new implementation of bind_port() will actually raise an exception
3559 if it is passed an AF_INET/SOCK_STREAM socket with either the
3560 SO_REUSEADDR or SO_REUSEPORT socket option set. Furthermore, if
3561 available, bind_port() will set the SO_EXCLUSIVEADDRUSE option on
3562 the socket it's been passed. This currently only applies to
3563 Windows. This option prevents any other sockets from binding to the
3564 host/port we've bound to, thus removing the possibility of the
3565 'non-deterministic' behaviour, as Microsoft puts it, that occurs
3566 when a second SOCK_STREAM socket binds and accepts to a host/port
3567 that's already been bound by another socket. The optional preferred
3568 port parameter to bind_port() has been removed. Under no
3569 circumstances should tests be hard coding ports!
3570
3571 test_support.find_unused_port() has also been introduced, which will
3572 pass a temporary socket object to bind_port() in order to obtain an
3573 unused port. The temporary socket object is then closed and
3574 deleted, and the port is returned. This method should only be used
3575 for obtaining an unused port in order to pass to an external program
3576 (i.e. the -accept [port] argument to openssl's s_server mode) or as
3577 a parameter to a server-oriented class that doesn't give you direct
3578 access to the underlying socket used.
3579
3580 Finally, test_support.HOST has been introduced, which should be used
3581 for the host argument of any relevant socket calls (i.e. bind and
3582 connect).
Trent Nelsone41b0062008-04-08 23:47:30 +00003583
3584 The following tests were updated to following the new conventions:
Georg Brandl3ee81df2008-05-17 18:14:43 +00003585 test_socket, test_smtplib, test_asyncore, test_ssl, test_httplib,
Trent Nelsone41b0062008-04-08 23:47:30 +00003586 test_poplib, test_ftplib, test_telnetlib, test_socketserver,
3587 test_asynchat and test_socket_ssl.
3588
Georg Brandl3ee81df2008-05-17 18:14:43 +00003589 It is now possible for multiple instances of the regression test
3590 suite to run in parallel without issue.

3757 values on 32-bit vs. 64-bit python interpreters. Both were correct,
3758 but they now both return a signed integer object for consistency.

Georg Brandl3ee81df2008-05-17 18:14:43 +00003774 optional: it defaults to the traceback of the exception that is
3775 currently being handled (is mandatory to be in the middle of an
3776 exception, otherwise it raises ValueError).

3793
Thomas Heller78b8f442008-03-05 14:53:39 +00003794- The bundled libffi copy is now in sync with the recently released
3795 libffi3.0.4 version, apart from some small changes to
Georg Brandl3ee81df2008-05-17 18:14:43 +00003796 Modules/_ctypes/libffi/configure.ac. On OS X, preconfigured libffi
3797 files are used. On all linux systems the --with-system-ffi

3857-----------------
3858
Fred Drakea8ee94b2008-03-01 02:45:07 +00003859- Issue #2051: pyc and pyo files are no longer created with permission
Barry Warsaw52973612008-03-01 02:23:38 +00003860 644. The mode is now inherited from the py file.
Christian Heimes40346852008-02-23 17:52:07 +00003861
Georg Brandlad61bc82008-02-23 15:11:18 +00003862- Issue #2067: file.__exit__() now calls subclasses' close() method.
3863
3864- Patch #1759: Backport of PEP 3129 class decorators.
Christian Heimes5224d282008-02-23 15:01:05 +00003865
Vinay Sajipb7edfc42008-04-02 21:10:23 +00003866- Issue #1881: An internal parser limit has been increased. Also see
Facundo Batistafc2d0102008-02-23 12:01:13 +00003867 issue 215555 for a discussion.
3868
Eric Smitha73fbe72008-02-23 03:09:44 +00003869- Added the future_builtins module, which contains hex() and oct().
3870 These are the PEP 3127 version of these functions, designed to be
3871 compatible with the hex() and oct() builtins from Python 3.0. They
3872 differ slightly in their output formats from the existing, unchanged
3873 Python 2.6 builtins. The expected usage of the future_builtins
3874 module is:
3875 from future_builtins import hex, oct
3876
Eric Smith7ef40bf2008-02-20 23:34:22 +00003877- Issue #1600: Modifed PyOS_ascii_formatd to use at most 2 digit
3878 exponents for exponents with absolute value < 100. Follows C99
3879 standard. This is a change on Windows, which would use 3 digits.
3880 Also, added 'n' to the formats that PyOS_ascii_formatd understands,
3881 so that any alterations it does to the resulting string will be
3882 available in stringlib/formatter.h (for float.__format__).
3883
Eric Smith5a3c1352008-02-19 13:21:56 +00003884- Implemented PEP 3101, Advanced String Formatting. This adds a new
3885 builtin format(); a format() method for str and unicode; a
3886 __format__() method to object, str, unicode, int, long, float, and
3887 datetime; the class string.Formatter; and the C API
3888 PyObject_Format().
3889
Georg Brandl3ee81df2008-05-17 18:14:43 +00003890- Fixed several potential crashes, all caused by specially crafted
3891 __del__ methods exploiting objects in temporarily inconsistent
3892 state.
Amaury Forgeot d'Arc632fad32008-02-16 20:55:24 +00003893
Vinay Sajipb7edfc42008-04-02 21:10:23 +00003894- Issue #2115: Important speedup in setting __slot__ attributes. Also
Georg Brandl3ee81df2008-05-17 18:14:43 +00003895 prevent a possible crash: an Abstract Base Class would try to access
3896 a slot on a registered virtual subclass.
Amaury Forgeot d'Arc60d6c7f2008-02-15 21:22:45 +00003897
Georg Brandl3ee81df2008-05-17 18:14:43 +00003898- Fixed repr() and str() of complex numbers with infinity or nan as
3899 real or imaginary part.
Christian Heimes2f0da532008-02-15 06:57:08 +00003900
Georg Brandl3ee81df2008-05-17 18:14:43 +00003901- Clear all free lists during a gc.collect() of the highest generation
3902 in order to allow pymalloc to free more arenas. Python may give back
3903 memory to the OS earlier.
Christian Heimes3b718a72008-02-14 12:47:33 +00003904
Georg Brandl3ee81df2008-05-17 18:14:43 +00003905- Issue #2045: Fix an infinite recursion triggered when printing a
3906 subclass of collections.defaultdict, if its default_factory is set
3907 to a bound method.
Amaury Forgeot d'Arcb01aa432008-02-08 00:56:02 +00003908
Christian Heimesf75dbef2008-02-08 00:11:31 +00003909- Fixed a minor memory leak in dictobject.c. The content of the free
3910 list was not freed on interpreter shutdown.
3911
Georg Brandl21e99f42010-03-07 15:23:59 +00003912- Limit free list of method and built-in function objects to 256
Georg Brandl3ee81df2008-05-17 18:14:43 +00003913 entries each.
Christian Heimes6075a822008-02-06 12:44:34 +00003914
Georg Brandl3ee81df2008-05-17 18:14:43 +00003915- Patch #1953: Added ``sys._compact_freelists()`` and the C API
3916 functions ``PyInt_CompactFreeList`` and ``PyFloat_CompactFreeList``
Christian Heimes422051a2008-02-04 18:00:12 +00003917 to compact the internal free lists of pre-allocted ints and floats.
3918
Georg Brandl3ee81df2008-05-17 18:14:43 +00003919- Issue #1983: Fixed return type of fork(), fork1() and forkpty()
3920 calls. Python expected the return type int but the fork familie
3921 returns pi_t.
Christian Heimes951cc0f2008-01-31 23:08:23 +00003922
Georg Brandl3ee81df2008-05-17 18:14:43 +00003923- Issue #1678380: Fix a bug that identifies 0j and -0j when they
3924 appear in the same code unit.
Mark Dickinson105be772008-01-31 22:17:37 +00003925
Georg Brandl3ee81df2008-05-17 18:14:43 +00003926- Issue #2025: Add tuple.count() and tuple.index() methods to comply
3927 with the collections.Sequence API.
Raymond Hettinger5b07ebc2008-02-07 00:54:20 +00003928

Georg Brandl3ee81df2008-05-17 18:14:43 +00003932- Added ``PyType_ClearCache()`` and ``sys._clear_type_cache`` to clear
3933 the internal lookup cache for ref leak tests.
Christian Heimes908caac2008-01-27 23:34:59 +00003934
Georg Brandl3ee81df2008-05-17 18:14:43 +00003935- Patch #1473257: generator objects gain a gi_code attribute. This is
3936 the same object as the func_code attribute of the function that
3937 produced the generator.
Georg Brandl0cdf9a32008-01-26 14:14:20 +00003938
Georg Brandl3ee81df2008-05-17 18:14:43 +00003939- Issue #1920: "while 0" statements were completely removed by the
3940 compiler, even in the presence of an "else" clause, which is
3941 supposed to be run when the condition is false. Now the compiler
3942 correctly emits bytecode for the "else" suite.
Amaury Forgeot d'Arc31eaafe2008-01-24 22:59:25 +00003943
Guido van Rossumeead05f2008-01-24 18:21:02 +00003944- A few crashers fixed: weakref_in_del.py (issue #1377858);
3945 loosing_dict_ref.py (issue #1303614, test67.py);
3946 borrowed_ref_[34].py (not in tracker).
3947
Vinay Sajipd7cf32e2008-01-24 12:43:33 +00003948- Issue #1069410: The "can't load dll" message box on Windows is
Christian Heimesb2302ba2008-01-23 17:15:06 +00003949 suppressed while an extension is loaded by calling SetErrorMode in
3950 dynload_win.c. The error is still reported properly.
3951
Georg Brandl3ee81df2008-05-17 18:14:43 +00003952- Issue #1915: Python compiles with --enable-unicode=no again. However
Christian Heimes082c9b02008-01-23 14:20:50 +00003953 several extension methods and modules do not work without unicode
3954 support.
3955
Georg Brandl26543b12008-01-21 18:36:51 +00003956- Issue #1882: when compiling code from a string, encoding cookies in the
3957 second line of code were not always recognized correctly.
3958
Georg Brandl14404b62008-01-19 19:27:05 +00003959- Issue #1679: "0x" was taken as a valid integer literal.
3960
Georg Brandl6caad7d2008-01-26 14:19:22 +00003961- Issue #1865: ``bytes`` as an alias for ``str`` and b"" as an alias "" were
Christian Heimes288e89a2008-01-18 18:24:07 +00003962 added.
3963
Christian Heimesc94e2b52008-01-14 04:13:37 +00003964- sys.float_info / PyFloat_GetInfo: The floating point information
3965 object was converted from a dict to a specialized structseq object.
3966
Georg Brandl3ee81df2008-05-17 18:14:43 +00003967- Patch #1816: Added sys.flags structseq. It exposes the status of
3968 most command line arguments and PYTHON* environment variables.
Christian Heimesf31b69f2008-01-14 03:42:48 +00003969
Georg Brandl3ee81df2008-05-17 18:14:43 +00003970- Objects/structseq.c: Implemented new structseq representation. The
3971 patch makes structseqs (e.g. the return value of os.stat) more
3972 readable.
Christian Heimes9c201962008-01-14 03:33:52 +00003973
Georg Brandl3ee81df2008-05-17 18:14:43 +00003974- Patch #1700288: added a type attribute cache that caches method
3975 accesses, resulting in speedups in heavily object-oriented code.

3983 envvar and sys.dont_write_bytecode attribute. All these can be set
3984 to forbid Python to attempt to write compiled bytecode files.
Georg Brandl2da0fce2008-01-07 17:09:35 +00003985
Georg Brandl3ee81df2008-05-17 18:14:43 +00003986- Improve some exception messages when Windows fails to load an
3987 extension module. Now we get for example '%1 is not a valid Win32
3988 application' instead of 'error code 193'.
Amaury Forgeot d'Arce0b76952008-01-04 02:04:15 +00003989

Georg Brandl3ee81df2008-05-17 18:14:43 +00003996 and INF. float("nan"), float("inf") and float("-inf") now work on
3997 every platform with IEEE 754 semantics.

Georg Brandl3ee81df2008-05-17 18:14:43 +00003999- Compiler now generates simpler and faster code for dictionary
4000 literals. The oparg for BUILD_MAP now indicates an estimated
4001 dictionary size. There is a new opcode, STORE_MAP, for adding
4002 entries to the dictionary.

4014
Nick Coghlanef01d822007-12-03 12:55:17 +00004015- PEP 366: Allow explicit relative imports when executing modules

Georg Brandl3ee81df2008-05-17 18:14:43 +00004031- Patch #1739468: Directories and zipfiles containing a __main__.py
4032 file can now be directly executed by passing their name to the
4033 interpreter. The directory/zipfile is automatically inserted as the
4034 first entry in sys.path.

Georg Brandl3ee81df2008-05-17 18:14:43 +00004036- Issue #1265: Fix a problem with sys.settrace, if the tracing
4037 function uses a generator expression when at the same time the
4038 executed code is closing a paused generator.
Amaury Forgeot d'Arc0d75f092007-11-13 21:54:28 +00004039
Raymond Hettinger1760c8a2007-11-08 02:52:43 +00004040- sets and frozensets now have an isdisjoint() method.

4045
Georg Brandl21e99f42010-03-07 15:23:59 +00004046- The enumerate() built-in function is no longer bounded to sequences
Georg Brandl3ee81df2008-05-17 18:14:43 +00004047 smaller than LONG_MAX. Formerly, it raised an OverflowError. Now,
4048 automatically shifts from ints to longs.
Raymond Hettinger8f669372007-10-03 21:18:11 +00004049
Georg Brandl3ee81df2008-05-17 18:14:43 +00004050- Issue #1686386: Tuple's tp_repr did not take into account the
4051 possibility of having a self-referential tuple, which is possible
4052 from C code. Nor did object's tp_str consider that a type's tp_str
4053 could do something that could lead to an inifinite recursion.
4054 Py_ReprEnter() and Py_EnterRecursiveCall(), respectively, fixed the
4055 issues.
Brett Cannon0b14f242007-09-30 19:45:10 +00004056
Georg Brandl3ee81df2008-05-17 18:14:43 +00004057- Issue #1164: It was possible to trigger deadlock when using the
4058 'print' statement to write to a file since the GIL was not released
4059 as needed. Now PyObject_Print() does the right thing along with
4060 various tp_print implementations of the built-in types and those in
4061 the collections module.
Brett Cannon01531592007-09-17 03:28:34 +00004062
Georg Brandl3ee81df2008-05-17 18:14:43 +00004063- Issue #1147: Exceptions were directly allowing string exceptions in
4064 their throw() method even though string exceptions no longer
4065 allowed.

Georg Brandl3ee81df2008-05-17 18:14:43 +00004067- Issue #1096: Prevent a segfault from getting the repr of a very
4068 deeply nested list by using the recursion counter.
Brett Cannona0c05512007-09-10 21:38:27 +00004069
Brett Cannon1e534b52007-09-07 04:18:30 +00004070- Issue #1202533: Fix infinite recursion calls triggered by calls to
Georg Brandl3ee81df2008-05-17 18:14:43 +00004071 PyObject_Call() never calling back out to Python code to trigger
4072 recursion depth updates/checks. Required the creation of a static
4073 RuntimeError instance in case normalizing an exception put the
4074 recursion check value past its limit. Fixes crashers
4075 infinite_rec_(1|2|4|5).py.
Brett Cannon1e534b52007-09-07 04:18:30 +00004076
Georg Brandl3ee81df2008-05-17 18:14:43 +00004077- Patch #1031213: Decode source line in SyntaxErrors back to its

Neal Norwitz0ac60192007-05-27 04:08:54 +00004090- Add new attribute names for function objects. All the func_* become
Georg Brandl3ee81df2008-05-17 18:14:43 +00004091 __*__ attributes. (Some already existed, e.g., __doc__ and
4092 __name__.)
Neal Norwitz0ac60192007-05-27 04:08:54 +00004093
Neal Norwitz8b2bfbc2007-05-23 06:35:32 +00004094- Add -3 option to the interpreter to warn about features that are
4095 deprecated and will be changed/removed in Python 3.0.
4096
Georg Brandl2134e752007-05-21 20:34:16 +00004097- Patch #1686487: you can now pass any mapping after '**' in function
4098 calls.
4099
Collin Winter62903052007-05-18 23:11:24 +00004100- except clauses may now be spelled either "except E, target:" or
Georg Brandl3ee81df2008-05-17 18:14:43 +00004101 "except E as target:". This is to provide forwards compatibility
4102 with Python 3.0.
Collin Winter62903052007-05-18 23:11:24 +00004103
Brett Cannon229cee22007-05-05 01:34:02 +00004104- Deprecate BaseException.message as per PEP 352.
4105
Georg Brandl3ee81df2008-05-17 18:14:43 +00004106- Issue #1303614: don't expose object's __dict__ when the dict is
Georg Brandl21e99f42010-03-07 15:23:59 +00004107 inherited from a built-in base.
Armin Rigo9790a272007-05-02 19:23:31 +00004108
Vinay Sajip8549ce32007-05-06 17:53:37 +00004109- When __slots__ are set to a unicode string, make it work the same as
Neal Norwitzcbd9ee62007-04-14 05:25:50 +00004110 setting a plain string, ie don't expand to single letter identifiers.
4111
Raymond Hettinger13936692007-04-11 18:40:58 +00004112- Request #1191699: Slices can now be pickled.
4113
Raymond Hettinger4db5fe92007-04-12 04:10:00 +00004114- Request #1193128: str.translate() now allows a None argument for
4115 translations that only remove characters without re-mapping the
4116 remaining characters.
4117
Georg Brandl5cb76c12007-03-21 09:00:39 +00004118- Patch #1682205: a TypeError while unpacking an iterable is no longer
4119 masked by a generic one with the message "unpack non-sequence".
4120
Neal Norwitzaa754b72007-03-21 06:39:48 +00004121- Remove unused file Python/fmod.c.
4122
Guido van Rossum143b5642007-03-23 04:58:42 +00004123- Bug #1683368: The object.__init__() and object.__new__() methods are
4124 now stricter in rejecting excess arguments. The only time when
4125 either allows excess arguments is when it is not overridden and the
4126 other one is. For backwards compatibility, when both are
4127 overridden, it is a deprecation warning (for now; maybe a Py3k
Guido van Rossum234b1ff2007-03-23 19:39:01 +00004128 warning later). Also, type.__init__() insists on the same signature
4129 as supported by type.__new__().
Guido van Rossum143b5642007-03-23 04:58:42 +00004130
Georg Brandl3ee81df2008-05-17 18:14:43 +00004131- Patch #1675423: PyComplex_AsCComplex() now tries to convert an
4132 object to complex using its __complex__() method before falling back
4133 to the __float__() method. Therefore, the functions in the cmath
4134 module now can operate on objects that define a __complex__()
4135 method.
Georg Brandl2b869942007-03-17 16:08:45 +00004136
Georg Brandl3ee81df2008-05-17 18:14:43 +00004137- Patch #1623563: allow __class__ assignment for classes with
4138 __slots__. The old and the new class are still required to have the
4139 same slot names.
Žiga Seilnacht6f2d09c2007-03-16 11:59:38 +00004140
Georg Brandl3ee81df2008-05-17 18:14:43 +00004141- Patch #1642547: Fix an error/crash when encountering syntax errors

4145 ``object.__reduce_ex__()`` is called with an object that is faking
4146 its type.
Žiga Seilnacht20f43d32007-03-15 11:44:55 +00004147
Georg Brandl3ee81df2008-05-17 18:14:43 +00004148- Patch #1680015: Don't modify __slots__ tuple if it contains an

4152
Georg Brandl7b9c5552007-03-12 14:30:05 +00004153- Bug #1678647: write a newline after printing an exception in any
4154 case, even when converting the value to a string failed.
4155
Georg Brandl871f1bc2007-03-12 13:17:36 +00004156- The dir() function has been extended to call the __dir__() method on
Georg Brandl3ee81df2008-05-17 18:14:43 +00004157 its argument, if it exists. If not, it will work like before. This
4158 allows customizing the output of dir() in the presence of a
4159 __getattr__().
Georg Brandl871f1bc2007-03-12 13:17:36 +00004160
Collin Winter276887b2007-03-12 16:11:39 +00004161- Patch #922167: Python no longer segfaults when faced with infinitely
4162 self-recursive reload() calls (as reported by bug #742342).
4163
Georg Brandl3ee81df2008-05-17 18:14:43 +00004164- Patch #1675981: remove unreachable code from ``type.__new__()``
4165 method.

Georg Brandl3ee81df2008-05-17 18:14:43 +00004167- Patch #1491866: change the complex() constructor to allow
4168 parthensized forms. This means complex(repr(x)) now works instead of
4169 raising a ValueError.
Collin Wintere38051d2007-03-09 20:33:07 +00004170
Georg Brandlaa2321b2007-03-07 00:40:28 +00004171- Patch #703779: unset __file__ in __main__ after running a file. This
Georg Brandl3ee81df2008-05-17 18:14:43 +00004172 makes the filenames the warning module prints much more sensible
4173 when a PYTHONSTARTUP file is used.
Georg Brandlaa2321b2007-03-07 00:40:28 +00004174

4176 exception if the -i command line option or PYTHONINSPECT environment
Georg Brandl3ee81df2008-05-17 18:14:43 +00004177 variable is given, but break into the interactive interpreter just
4178 like on other exceptions or normal program exit.

Georg Brandl098cd692007-03-06 12:17:50 +00004185
Georg Brandl0fca97a2007-03-05 22:28:08 +00004186- Patch #1674228: when assigning a slice (old-style), check for the
4187 sq_ass_slice instead of the sq_slice slot.
4188
Georg Brandl3ee81df2008-05-17 18:14:43 +00004189- When printing an unraisable error, don't print exceptions. before
4190 the name. This duplicates the behavior whening normally printing
4191 exceptions.

Guido van Rossum8bc09652008-02-21 18:18:37 +00004333- Removed uses of dict.has_key() from distutils, and uses of

Georg Brandl3ee81df2008-05-17 18:14:43 +00004742- Patch #1530482: add pydoc.render_doc() which returns the

4757
Georg Brandl92a6bae2007-03-13 17:43:32 +00004758- Patch #1603688: ConfigParser.SafeConfigParser now checks values that
Georg Brandl3ee81df2008-05-17 18:14:43 +00004759 are set for invalid interpolation sequences that would lead to
4760 errors on reading back those values.

4814
Georg Brandl3ee81df2008-05-17 18:14:43 +00004815- unittest now verifies more of its assumptions. In particular,
4816 TestCase and TestSuite subclasses (not instances) are no longer
4817 accepted in TestSuite.addTest(). This should cause no
4818 incompatibility since it never made sense with ordinary subclasses
4819 -- the failure just occurred later, with a more cumbersome
4820 exception.

Gregory P. Smithbde4ae42008-01-17 08:35:49 +00005107 that the SMTP.starttls() caller no longer needs to call ehlo()

Georg Brandl3ee81df2008-05-17 18:14:43 +00005109 does not claim to support starttls. Adds the

Gregory P. Smithec10a4a2007-11-05 02:32:26 +00005208- pybsddb.sf.net Bug #477182: Load the database flags at database open
Georg Brandl3ee81df2008-05-17 18:14:43 +00005209 time so that opening a database previously created with the DB_DUP
5210 or DB_DUPSORT flag set will keep the proper behavior on subsequent
5211 opens. Specifically: dictionary assignment to a DB object will
5212 replace all values for a given key when the database allows
5213 duplicate values. DB users should use DB.put(k, v) when they want
5214 to store duplicates; not DB[k] = v.

5223 behavior of quoting dots if they are the second character of any

Raymond Hettingerdc1d1ba2007-11-07 02:45:46 +00005493- Add a FAST_LOOPS build option that speeds-up looping by trading away
Georg Brandl3ee81df2008-05-17 18:14:43 +00005494 periodic threadstate and signal checking in tight loops. By
5495 default, this option is turned-off. It should only be enabled in
5496 debugged, performance critical applications.

Christian Heimes5b970ad2008-02-06 13:33:44 +00005553
Georg Brandl3ee81df2008-05-17 18:14:43 +00005554- ``PySet_Add()`` can now modify a newly created frozenset. Similarly
5555 to ``PyTuple_SetItem``, it can be used to populate a brand new

5568
Georg Brandl3ee81df2008-05-17 18:14:43 +00005569- Issue #1521: On 64bit platforms, using PyArgs_ParseTuple with the t#
5570 of w# format code incorrectly truncated the length to an int, even
5571 when PY_SSIZE_T_CLEAN is set. The str.decode method used to return
5572 incorrect results with huge strings.

5600 imports under some conditions.
Christian Heimes000a0742008-01-03 22:16:32 +00005601
Georg Brandl3ee81df2008-05-17 18:14:43 +00005602- Added case insensitive comparison methods ``PyOS_stricmp(char*,
5603 char*)`` and ``PyOS_strnicmp(char*, char*, Py_ssize_t)``.
Christian Heimes000a0742008-01-03 22:16:32 +00005604
Georg Brandl3ee81df2008-05-17 18:14:43 +00005605- Bug #1542693: remove semi-colon at end of PyImport_ImportModuleEx
