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.
67
Vinay Sajipb0623d62010-03-24 14:31:21 +000068- logging: Added LOG_FTP to SysLogHandler and updated documentation.
69
Florent Xicluna176cda12010-03-22 22:52:11 +000070- Issue #8205: Remove the "Modules" directory from sys.path when Python is
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.
100

105 or memoryviews.
106
Matthias Klose8b411682010-03-16 10:48:52 +0000107- Issue #4961: Inconsistent/wrong result of askyesno function in tkMessageBox

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

139
Matthias Klosee9fbf2b2010-03-19 14:45:06 +0000140- Issue #1039, #8154: Fix os.execlp() crash with missing 2nd argument.

143 http://www.jcea.es/programacion/pybsddb.htm#bsddb3-4.8.4.
144 This update drops support for Berkeley DB 4.0, and adds support for 4.8.
Matthias Klose54cc5392010-03-15 12:46:18 +0000145
Matthias Klose817acef2010-03-15 00:02:36 +0000146- Issue #8142: Update libffi to the 3.0.9 release.
147
Georg Brandlba83f822010-03-14 09:50:54 +0000148- Issue #1530559: When passing a non-integer argument to struct.pack with *any*
149 integer format code (one of 'bBhHiIlLqQ'), struct.pack attempts to use the
150 argument's __int__ method to convert to an integer before packing. It also
151 produces a DeprecationWarning in this case. (In Python 2.6, the behaviour
152 was inconsistent: __int__ was used for some integer codes but not for others,
153 and the set of integer codes for which it was used differed between native
154 packing and standard packing.)

183 function declaration, which was kept for backwards compatibility reasons,
184 is now removed (the macro was introduced in 1997!).
185
Larry Hastings402b73f2010-03-25 00:54:54 +0000186- Issue #7992: A replacement PyCObject API, PyCapsule, has been backported
Larry Hastings5ac006d2010-04-02 11:01:35 +0000187 from Python 3.1. All existing Python CObjects in the main distribution
188 have been converted to capsules. To address backwards-compatibility
189 concerns, PyCObject_AsVoidPtr() was changed to understand capsules.

Antoine Pitrouf3fa0742010-01-31 22:26:04 +0000434- Issue #6939: Fix file I/O objects in the `io` module to keep the original
Georg Brandlba83f822010-03-14 09:50:54 +0000435 file position when calling `truncate()`. It would previously change the file
436 position to the given argument, which goes against the tradition of
Antoine Pitrouf3fa0742010-01-31 22:26:04 +0000437 ftruncate() and other truncation APIs. Patch by Pascal Chambon.

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

533Core and Builtins
534-----------------
535
Georg Brandlba83f822010-03-14 09:50:54 +0000536- The ``__complex__()`` method is now looked up on the class of instances to
537 make it consistent with other special methods.
Benjamin Petersonecdae192010-01-04 00:43:01 +0000538
Antoine Pitrou5b7139a2010-01-02 21:12:58 +0000539- Issue #7462: Implement the stringlib fast search algorithm for the `rfind`,
540 `rindex`, `rsplit` and `rpartition` methods. Patch by Florent Xicluna.
541
Mark Dickinson1b34d252010-01-01 17:27:30 +0000542- Issue #5080: A number of functions and methods previously produced a
Georg Brandlba83f822010-03-14 09:50:54 +0000543 DeprecationWarning when passed a float argument where an integer was expected.
544 These functions and methods now raise TypeError instead. The majority of the
545 effects of this change are in the extension modules, but some core functions
546 and methods are affected: notably the 'chr', 'range' and 'xrange' builtins,
547 and many unicode/str methods.

558 used to drop the time part of the result.
559
Georg Brandlba83f822010-03-14 09:50:54 +0000560- Issue #1811: Improve accuracy and cross-platform consistency for true division
561 of integers: the result of a/b is now correctly rounded for ints a and b (at
562 least on IEEE 754 platforms), and in particular does not depend on the
563 internal representation of a long.
Mark Dickinson46572832009-12-27 14:55:57 +0000564
Georg Brandlba83f822010-03-14 09:50:54 +0000565- Issue #6108: ``unicode(exception)`` and ``str(exception)`` should return the
566 same message when only ``__str__()`` (and not ``__unicode__()``) is overridden
567 in the subclass.
Ezio Melottif84caf42009-12-24 22:25:17 +0000568

Ronald Oussoren92919a62009-12-24 13:30:58 +0000570 executables on OSX.
571
Georg Brandlba83f822010-03-14 09:50:54 +0000572 These executables now work properly with the arch(1) command: ``arch -ppc
573 python`` will start a universal binary version of python in PPC mode (unlike
574 previous releases).
Ronald Oussoren92919a62009-12-24 13:30:58 +0000575
Georg Brandlba83f822010-03-14 09:50:54 +0000576- Issue #1680159: Unicode coercion during an 'in' operation no longer masks the

635 the same as passing no argument.
636

Georg Brandlba83f822010-03-14 09:50:54 +0000712- Issue #3382: 'F' formatting for float and complex now convert the result to

714 to 'g' for large values.
Amaury Forgeot d'Arcd7288712009-12-01 21:51:04 +0000715
Georg Brandlba83f822010-03-14 09:50:54 +0000716- Remove switch from "%f" formatting to "%g" formatting for floats larger than
717 1e50 in absolute value.
Mark Dickinson9dd5e162009-11-23 20:54:09 +0000718
Georg Brandlba83f822010-03-14 09:50:54 +0000719- Remove restrictions on precision when formatting floats. E.g., "%.120g" %
720 1e-100 used to raise OverflowError, but now gives the requested 120
721 significant digits instead.

Ronald Oussoren315cd0c2009-11-19 16:25:21 +0000729
Georg Brandlba83f822010-03-14 09:50:54 +0000730- Issue #7117: ``repr(x)`` for a float x returns a result based on the shortest
731 decimal string that's guaranteed to round back to x under correct rounding
732 (with round-half-to-even rounding mode). Previously it gave a string based on
733 rounding x to 17 decimal digits. repr(x) for a complex number behaves
734 similarly. On platforms where the correctly-rounded strtod and dtoa code is
735 not supported (see below), repr is unchanged.
Mark Dickinsonb678de82009-11-19 18:41:49 +0000736
Georg Brandlba83f822010-03-14 09:50:54 +0000737- Issue #7117: On almost all platforms: float-to-string and string-to-float
738 conversions within Python are now correctly rounded. Places these conversions
739 occur include: str for floats and complex numbers; the float and complex
740 constructors; old-style and new-style numeric formatting; serialization and
741 deserialization of floats and complex numbers using marshal, pickle and json;
742 parsing of float and imaginary literals in Python code; Decimal-to-float
743 conversion.
Mark Dickinsonb678de82009-11-19 18:41:49 +0000744
Georg Brandlba83f822010-03-14 09:50:54 +0000745 The conversions use a Python-adapted version of David Gay's well-known dtoa.c,
746 providing correctly-rounded strtod and dtoa C functions. This code is
747 supported on Windows, and on Unix-like platforms using gcc, icc or suncc as
748 the C compiler. There may be a small number of platforms on which correct
749 operation of this code cannot be guaranteed, so the code is not used: notably,
750 this applies to platforms where the C double format is not IEEE 754 binary64,
751 and to platforms on x86 hardware where the x87 FPU is set to 64-bit precision
752 and Python's configure script is unable to determine how to change the FPU
753 precision. On these platforms conversions use the platform strtod and dtoa,
754 as before.
Mark Dickinsonb678de82009-11-19 18:41:49 +0000755
Georg Brandlba83f822010-03-14 09:50:54 +0000756- Issue #7117: Backport round implementation from Python 3.x. ``round()`` now
757 uses the correctly-rounded string <-> float conversions described above (when
758 available), and so produces correctly rounded results that will display nicely
759 under the float repr. There are two related small changes: (1) round now

1142 this code path is really executed because I cannot move to such directory on

1169 PyUnicode_DecodeUTF8() once, remember the result and output it in a second

2545
Amaury Forgeot d'Arc05e34492008-09-10 22:04:45 +00002546- Issue #3743: In a few places, PY_FORMAT_SIZE_T was incorrectly used with
2547 PyString_FromFormat or PyErr_Format to display size_t values. The macro
2548 PY_FORMAT_SIZE_T is designed to select the correct format for the OS
2549 ``printf`` function, whereas PyString_FromFormat has an independent
2550 implementation and uses "%zd" on all platforms for size_t values.
2551 This makes a difference on win64, where ``printf`` needs "%Id" to display
2552 64bit values.

Antoine Pitrou0668c622008-08-26 22:42:08 +00002572 match Python 2.5 speed despite the __instancecheck__ / __subclasscheck__
2573 mechanism. In the process, fix a bug where isinstance() and issubclass(),
2574 when given a tuple of classes as second argument, were looking up
2575 __instancecheck__ / __subclasscheck__ on the tuple rather than on each
2576 type object.

2647 warnings.catch_warnings() along with some API cleanup. Expanding the tests
2648 for catch_warnings() also led to an improvement in the raising of a
2649 DeprecationWarning related to warnings.warn_explicit().
2650

2673
Amaury Forgeot d'Arc293924b2008-09-02 23:19:56 +00002674- Issue #2975: When compiling several extension modules with Visual Studio 2008
2675 from the same python interpreter, some environment variables would grow
2676 without limit.
2677
Benjamin Peterson37346b22008-08-23 20:27:43 +00002678- Issue #3643: Added a few more checks to _testcapi to prevent segfaults by

Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00002715What's New in Python 2.6 beta 3?
2716================================
2717
Barry Warsaw07a4a382008-08-21 01:15:08 +00002718*Release date: 20-Aug-2008*
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00002719
2720Core and Builtins
2721-----------------
2722
Guido van Rossumf8402962008-08-20 15:01:50 +00002723- Issue #1878: Remove Py_TPFLAGS_HAVE_VERSION_TAG from
2724 Py_TPFLAGS_DEFAULT when not building the core. This means 3rd party
2725 extensions do not automatically benefit from the class attribute
2726 cache; they will have to explicitly add Py_TPFLAGS_HAVE_VERSION_TAG
2727 to their tp_flags field if they care. This is a backwards
2728 compatibility feature; in 3.0, all types will use the cache by
2729 default.
2730
Benjamin Petersonf647dc12008-08-20 01:27:30 +00002731- Keyword arguments can now follow starred arguments. (``f(a, *args,
2732 keyword=23)`` is now valid syntax.)
2733
Thomas Heller0ad5ae02008-08-19 19:25:04 +00002734- ctypes function pointers that are COM methods have a boolean True
2735 value again.
2736
Martin v. Löwisf91d46a2008-08-12 14:49:50 +00002737- Issue #3139: Make buffer-interface thread-safe wrt. PyArg_ParseTuple,
2738 by denying s# to parse objects that have a releasebuffer procedure,
2739 and introducing s*.
2740
Georg Brandl1e13ea92008-08-11 09:07:59 +00002741- Issue #3537: Fix an assertion failure when an empty but presized dict
2742 object was stored in the freelist.
2743
Mark Dickinsonb6467572008-08-04 21:30:09 +00002744- Issue #1481296: Make long(float('nan')) and int(float('nan')) raise
2745 ValueError consistently across platforms.
2746
Amaury Forgeot d'Arc39fd6722008-07-31 21:28:03 +00002747- Issue #3479: On platforms where sizeof(int) is smaller than sizeof(long)
2748 (64bit Unix, for example), unichr() would truncate its argument and return
2749 u'\x00' for unichr(2**32). Now it properly raises an OverflowError.
2750
Neal Norwitze7d8be82008-07-31 17:17:14 +00002751- Apply security patches from Apple.
2752
Amaury Forgeot d'Arc246daed2008-07-31 00:42:16 +00002753- Issue #2542: Now that issubclass() may call arbitrary code, ensure that
2754 PyErr_ExceptionMatches returns 0 when an exception occurs there.
2755
Antoine Pitrou92f82162008-07-25 22:22:08 +00002756- Issue #1819: function calls with several named parameters are now on
2757 average 35% faster (as measured by pybench).
2758
Amaury Forgeot d'Arce4921fe2008-07-21 22:00:38 +00002759- Issue #2378: An unexpected UnboundLocalError or NameError could appear when
2760 the python debugger steps into a class statement: the free variables (local
2761 variables defined in an outer scope) would be deleted from the outer scope.
2762
Gregory P. Smith0470bab2008-07-22 04:46:32 +00002763- Issue #2620: Overflow checking when allocating or reallocating memory
2764 was not always being done properly in some python types and extension
2765 modules. PyMem_MALLOC, PyMem_REALLOC, PyMem_NEW and PyMem_RESIZE have
2766 all been updated to perform better checks and places in the code that
2767 would previously leak memory on the error path when such an allocation
2768 failed have been fixed.
2769

2774
Benjamin Petersone977ad42008-08-20 01:42:01 +00002775- The methods ``is_in_tuple()``, ``is_vararg()``, and ``is_keywordarg()`` of
2776 symtable.Symbol have been deprecated for removal in 3.0 and the next release.
2777
Amaury Forgeot d'Arc351ffb82008-08-18 19:23:47 +00002778- Issue #2234: distutils failed for some versions of the cygwin compiler. The
2779 version reported by these tools does not necessarily follow the python
2780 version numbering scheme, so the module is less strict when parsing it.
2781
Nick Coghlanf70385a2008-08-18 12:42:46 +00002782- Issue #2235: Added Py3k warnings for types which will become unhashable
2783 under the stricter __hash__ inheritance rules in 3.0. Several types
2784 which did not meet the rules for hash invariants and were already
2785 unhashable in 3.0 have now been explicitly flagged as unhashable in
2786 2.6 as well (collections.Mapping, collections.Set, unittest.TestSuite,
2787 xml.dom.minidom.NamedNodeMap, numbers.Number, UserList.UserList)
2788
Brett Cannon88f801d2008-08-18 00:46:22 +00002789- Update __all__ for cookielib, csv, os, urllib2, and weakref to include things

2797
Hirokazu Yamamoto41a81eb2008-08-17 13:10:46 +00002798- Issue #3575: Incremental decoder's decode function now takes bytearray
2799 by using 's*' instead of 't#'.
2800
Mark Dickinson3e4caeb2009-02-21 20:27:01 +00002801- Issue #2222: Fixed reference leak when occurred os.rename()
Hirokazu Yamamoto7f30a682008-08-17 09:46:56 +00002802 fails unicode conversion on 2nd parameter. (windows only)
2803
Facundo Batista94f243a2008-08-17 03:38:39 +00002804- Issue 2464. urllib2 now supports a malformation in the URL received
2805 in a redirect.
2806
Brett Cannonabe423e2008-08-16 21:47:07 +00002807- Silence the DeprecationWarning raised when importing mimetools in
Brett Cannon721b1452008-08-16 22:00:27 +00002808 BaseHTTPServer, cgi (and rfc822), httplib.
Brett Cannonabe423e2008-08-16 21:47:07 +00002809
Facundo Batistaeb90b782008-08-16 14:44:07 +00002810- Issue #2776: fixed small issue when handling an URL with double slash
2811 after a 302 response in the case of not going through a proxy.
2812
Antoine Pitroub90a8be2008-08-15 21:03:21 +00002813- Issue #2676: in the email package, content-type parsing was hanging on
2814 pathological input because of quadratic or exponential behaviour of a
2815 regular expression.
2816
Antoine Pitrou11ec65d2008-08-14 21:04:30 +00002817- Issue #3476: binary buffered reading through the new "io" library is now
2818 thread-safe.
2819
Brett Cannonbf3157b2008-08-14 05:00:03 +00002820- Silence the DeprecationWarning of rfc822 when it is imported by mimetools
2821 since mimetools itself is deprecated. Because modules are cached, all
2822 subsequent imports of rfc822 will not raise a visible DeprecationWarning.
2823
Antoine Pitrou9fcd4b32008-08-11 17:21:36 +00002824- Issue #3134: shutil referenced undefined WindowsError symbol.
2825
Robert Schuppenies14646332008-08-10 11:01:53 +00002826- Issue #1342811: Fix leak in Tkinter.Menu.delete. Commands associated to
2827 menu entries were not deleted.
2828
Brett Cannon83e81842008-08-09 23:30:55 +00002829- Copied the implementation of reduce() to _functools.reduce() to have a
2830 version that did not raise a DeprecationWarning under -3.
2831
Antoine Pitrou76b8bee2008-08-09 17:27:23 +00002832- Issue #3205: When iterating over a BZ2File fails allocating memory, raise
2833 a MemoryError rather than silently stop the iteration.
2834
Guido van Rossum59ce9012008-08-09 14:55:34 +00002835- Issue #3487: sre "bytecode" validator. Passing invalid "re-bytecode"
2836 to _sre.compile() will now be rejected. This should not affect anybody
2837 since the re.compile() function never generates invalid re-bytecode.
2838
Skip Montanaroa032bf42008-08-08 22:52:51 +00002839- Issue #3436: Make csv.DictReader's fieldnames attribute a property so that

Antoine Pitroude781a42008-08-09 12:43:23 +00002858 asking for a specific length. This problem only affected files opened
2859 using the new "io" module, not the built-in open() function.

2886 mode 0600 rather than 000 under Unix.
2887
Gregory P. Smitha36f8fe2008-08-04 00:13:29 +00002888- Issue #1857: subprocess.Popen.poll gained an additional _deadstate keyword

Mark Dickinson64b7e502008-07-16 09:40:03 +00002921- Issue #3360: Fix incorrect parsing of '020000000000.0', which
2922 produced a ValueError instead of giving the correct float.
2923
Eric Smitha5fa5a22008-07-16 00:11:49 +00002924- Issue #3083: Add alternate (#) formatting for bin, oct, hex output

Nick Coghlan6d6bd442008-07-15 15:40:22 +00002931- Issue #2235: __hash__ is once again inherited by default. To allow
2932 collections.Hashable to remain meaningful in the presence of the
2933 default hash implementation (object.__hash__), it is now possible
2934 to explicit block inheritance of hash by setting __hash__=None at
2935 the Python level, or tp_hash=PyObject_HashNotImplemented at the C
2936 level.
2937
Nick Coghlanb028f502008-07-13 14:52:36 +00002938- Issue #3221: Issue a RuntimeWarning instead of raising SystemError if
2939 the parent module cannot be found while performing an absolute import.
2940 This means that an incorrectly defined __package__ attribute will
2941 now only prevent relative imports in that module rather than causing
2942 all imports from that module to fail.
2943
Nick Coghlan14ff9942008-07-08 14:21:42 +00002944- Issue #2517: Allow unicode messages in Exceptions again by correctly

2955
Mark Dickinson1ec2fcd2008-06-20 14:53:43 +00002956- Issue #3004: Minor change to slice.indices(): the start and stop
2957 arguments are now treated identically, making the behaviour easier
2958 to describe and understand. For example, slice(None, -10,
2959 1).indices(9) now returns (0, 0, 1) instead of (0, -1, 1), and
2960 slice(None, 10, -1).indices(10) returns (9, 9, -1) instead of (9,
2961 10, -1).

2964 f(a=2, a=23), would not cause a syntax error. This was a regression
2965 from 2.4 caused by the switch to the new compiler.

3004 both unnecessary (HTTP allows text content to be sent in several forms) and
Andrew M. Kuchlingcc3f2b12008-07-10 14:43:31 +00003005 wrong because the actual transmitted size could differ from the

Georg Brandl5cc774e2008-06-11 20:28:06 +00003415 PPC64 and x86_64 support in one binary).
Ronald Oussoren5640ce22008-06-05 12:58:24 +00003416
3417 This is controlled by the configure argument ``--with-universal-archs``:

3420
3421 - ``--with-universal-archs=32-bit``: install 2-way universal, 32-bit (the default)
3422
3423 - ``--with-universal-archs=64-bit``: install 2-way universal, 64-bit
3424
3425 This option should be used in combination with ``--enable-universalsdk=``.

3464 two handlers that derive the same default base class.

Christian Heimese74c8f22008-04-19 02:23:57 +00003466- Added kill, terminate and send_signal(sig) to subprocess.Popen.

Georg Brandl3ee81df2008-05-17 18:14:43 +00003477- Issue #1631171: Re-implement the 'warnings' module in C (the
3478 original Python code has been kept as backup). This will allow for
3479 using the 'warning's machinery in such places as the parser where
3480 use of pure Python code is not possible. Both the ``showarning()``
3481 and ``formatwarning()`` gain an optional 'line' argument which is
3482 not called by default for backwards-compatibility reasons. Setting
3483 ``warnings.showwarning()`` to an implementation that lacks support

Georg Brandl3ee81df2008-05-17 18:14:43 +00003547- Issue #2550: The approach used by client/server code for obtaining
3548 ports to listen on in network-oriented tests has been refined in an
3549 effort to facilitate running multiple instances of the entire
3550 regression test suite in parallel without issue.
3551 test_support.bind_port() has been fixed such that it will always
3552 return a unique port -- which wasn't always the case with the
3553 previous implementation, especially if socket options had been set
3554 that affected address reuse (i.e. SO_REUSEADDR, SO_REUSEPORT). The
3555 new implementation of bind_port() will actually raise an exception
3556 if it is passed an AF_INET/SOCK_STREAM socket with either the
3557 SO_REUSEADDR or SO_REUSEPORT socket option set. Furthermore, if
3558 available, bind_port() will set the SO_EXCLUSIVEADDRUSE option on
3559 the socket it's been passed. This currently only applies to
3560 Windows. This option prevents any other sockets from binding to the
3561 host/port we've bound to, thus removing the possibility of the
3562 'non-deterministic' behaviour, as Microsoft puts it, that occurs
3563 when a second SOCK_STREAM socket binds and accepts to a host/port
3564 that's already been bound by another socket. The optional preferred
3565 port parameter to bind_port() has been removed. Under no
3566 circumstances should tests be hard coding ports!
3567
3568 test_support.find_unused_port() has also been introduced, which will
3569 pass a temporary socket object to bind_port() in order to obtain an
3570 unused port. The temporary socket object is then closed and
3571 deleted, and the port is returned. This method should only be used
3572 for obtaining an unused port in order to pass to an external program
3573 (i.e. the -accept [port] argument to openssl's s_server mode) or as
3574 a parameter to a server-oriented class that doesn't give you direct
3575 access to the underlying socket used.
3576
3577 Finally, test_support.HOST has been introduced, which should be used
3578 for the host argument of any relevant socket calls (i.e. bind and
3579 connect).
Trent Nelsone41b0062008-04-08 23:47:30 +00003580
3581 The following tests were updated to following the new conventions:
Georg Brandl3ee81df2008-05-17 18:14:43 +00003582 test_socket, test_smtplib, test_asyncore, test_ssl, test_httplib,
Trent Nelsone41b0062008-04-08 23:47:30 +00003583 test_poplib, test_ftplib, test_telnetlib, test_socketserver,
3584 test_asynchat and test_socket_ssl.
3585
Georg Brandl3ee81df2008-05-17 18:14:43 +00003586 It is now possible for multiple instances of the regression test
3587 suite to run in parallel without issue.

Georg Brandl3ee81df2008-05-17 18:14:43 +00003753- Issue #1202: zlib.crc32 and zlib.adler32 no longer return different
3754 values on 32-bit vs. 64-bit python interpreters. Both were correct,
3755 but they now both return a signed integer object for consistency.

3855
Fred Drakea8ee94b2008-03-01 02:45:07 +00003856- Issue #2051: pyc and pyo files are no longer created with permission
Barry Warsaw52973612008-03-01 02:23:38 +00003857 644. The mode is now inherited from the py file.
Christian Heimes40346852008-02-23 17:52:07 +00003858
Georg Brandlad61bc82008-02-23 15:11:18 +00003859- Issue #2067: file.__exit__() now calls subclasses' close() method.
3860
3861- Patch #1759: Backport of PEP 3129 class decorators.
Christian Heimes5224d282008-02-23 15:01:05 +00003862
Vinay Sajipb7edfc42008-04-02 21:10:23 +00003863- Issue #1881: An internal parser limit has been increased. Also see
Facundo Batistafc2d0102008-02-23 12:01:13 +00003864 issue 215555 for a discussion.
3865
Eric Smitha73fbe72008-02-23 03:09:44 +00003866- Added the future_builtins module, which contains hex() and oct().
3867 These are the PEP 3127 version of these functions, designed to be
3868 compatible with the hex() and oct() builtins from Python 3.0. They
3869 differ slightly in their output formats from the existing, unchanged
3870 Python 2.6 builtins. The expected usage of the future_builtins
3871 module is:
3872 from future_builtins import hex, oct
3873
Eric Smith7ef40bf2008-02-20 23:34:22 +00003874- Issue #1600: Modifed PyOS_ascii_formatd to use at most 2 digit
3875 exponents for exponents with absolute value < 100. Follows C99
3876 standard. This is a change on Windows, which would use 3 digits.
3877 Also, added 'n' to the formats that PyOS_ascii_formatd understands,
3878 so that any alterations it does to the resulting string will be
3879 available in stringlib/formatter.h (for float.__format__).
3880
Eric Smith5a3c1352008-02-19 13:21:56 +00003881- Implemented PEP 3101, Advanced String Formatting. This adds a new
3882 builtin format(); a format() method for str and unicode; a
3883 __format__() method to object, str, unicode, int, long, float, and
3884 datetime; the class string.Formatter; and the C API
3885 PyObject_Format().
3886
Georg Brandl3ee81df2008-05-17 18:14:43 +00003887- Fixed several potential crashes, all caused by specially crafted
3888 __del__ methods exploiting objects in temporarily inconsistent
3889 state.
Amaury Forgeot d'Arc632fad32008-02-16 20:55:24 +00003890
Vinay Sajipb7edfc42008-04-02 21:10:23 +00003891- Issue #2115: Important speedup in setting __slot__ attributes. Also
Georg Brandl3ee81df2008-05-17 18:14:43 +00003892 prevent a possible crash: an Abstract Base Class would try to access
3893 a slot on a registered virtual subclass.
Amaury Forgeot d'Arc60d6c7f2008-02-15 21:22:45 +00003894
Georg Brandl3ee81df2008-05-17 18:14:43 +00003895- Fixed repr() and str() of complex numbers with infinity or nan as
3896 real or imaginary part.
Christian Heimes2f0da532008-02-15 06:57:08 +00003897
Georg Brandl3ee81df2008-05-17 18:14:43 +00003898- Clear all free lists during a gc.collect() of the highest generation
3899 in order to allow pymalloc to free more arenas. Python may give back
3900 memory to the OS earlier.
Christian Heimes3b718a72008-02-14 12:47:33 +00003901
Georg Brandl3ee81df2008-05-17 18:14:43 +00003902- Issue #2045: Fix an infinite recursion triggered when printing a
3903 subclass of collections.defaultdict, if its default_factory is set
3904 to a bound method.
Amaury Forgeot d'Arcb01aa432008-02-08 00:56:02 +00003905
Christian Heimesf75dbef2008-02-08 00:11:31 +00003906- Fixed a minor memory leak in dictobject.c. The content of the free
3907 list was not freed on interpreter shutdown.
3908
Georg Brandl21e99f42010-03-07 15:23:59 +00003909- Limit free list of method and built-in function objects to 256
Georg Brandl3ee81df2008-05-17 18:14:43 +00003910 entries each.
Christian Heimes6075a822008-02-06 12:44:34 +00003911
Georg Brandl3ee81df2008-05-17 18:14:43 +00003912- Patch #1953: Added ``sys._compact_freelists()`` and the C API
3913 functions ``PyInt_CompactFreeList`` and ``PyFloat_CompactFreeList``
Christian Heimes422051a2008-02-04 18:00:12 +00003914 to compact the internal free lists of pre-allocted ints and floats.
3915
Georg Brandl3ee81df2008-05-17 18:14:43 +00003916- Issue #1983: Fixed return type of fork(), fork1() and forkpty()
3917 calls. Python expected the return type int but the fork familie
3918 returns pi_t.
Christian Heimes951cc0f2008-01-31 23:08:23 +00003919
Georg Brandl3ee81df2008-05-17 18:14:43 +00003920- Issue #1678380: Fix a bug that identifies 0j and -0j when they

Georg Brandl3ee81df2008-05-17 18:14:43 +00003929- Added ``PyType_ClearCache()`` and ``sys._clear_type_cache`` to clear
3930 the internal lookup cache for ref leak tests.
Christian Heimes908caac2008-01-27 23:34:59 +00003931
Georg Brandl3ee81df2008-05-17 18:14:43 +00003932- Patch #1473257: generator objects gain a gi_code attribute. This is
3933 the same object as the func_code attribute of the function that
3934 produced the generator.
Georg Brandl0cdf9a32008-01-26 14:14:20 +00003935
Georg Brandl3ee81df2008-05-17 18:14:43 +00003936- Issue #1920: "while 0" statements were completely removed by the
3937 compiler, even in the presence of an "else" clause, which is
3938 supposed to be run when the condition is false. Now the compiler
3939 correctly emits bytecode for the "else" suite.
Amaury Forgeot d'Arc31eaafe2008-01-24 22:59:25 +00003940
Guido van Rossumeead05f2008-01-24 18:21:02 +00003941- A few crashers fixed: weakref_in_del.py (issue #1377858);
3942 loosing_dict_ref.py (issue #1303614, test67.py);
3943 borrowed_ref_[34].py (not in tracker).
3944
Vinay Sajipd7cf32e2008-01-24 12:43:33 +00003945- Issue #1069410: The "can't load dll" message box on Windows is
Christian Heimesb2302ba2008-01-23 17:15:06 +00003946 suppressed while an extension is loaded by calling SetErrorMode in
3947 dynload_win.c. The error is still reported properly.
3948
Georg Brandl3ee81df2008-05-17 18:14:43 +00003949- Issue #1915: Python compiles with --enable-unicode=no again. However
Christian Heimes082c9b02008-01-23 14:20:50 +00003950 several extension methods and modules do not work without unicode
3951 support.
3952
Georg Brandl26543b12008-01-21 18:36:51 +00003953- Issue #1882: when compiling code from a string, encoding cookies in the
3954 second line of code were not always recognized correctly.
3955
Georg Brandl14404b62008-01-19 19:27:05 +00003956- Issue #1679: "0x" was taken as a valid integer literal.
3957
Georg Brandl6caad7d2008-01-26 14:19:22 +00003958- Issue #1865: ``bytes`` as an alias for ``str`` and b"" as an alias "" were
Christian Heimes288e89a2008-01-18 18:24:07 +00003959 added.
3960
Christian Heimesc94e2b52008-01-14 04:13:37 +00003961- sys.float_info / PyFloat_GetInfo: The floating point information
3962 object was converted from a dict to a specialized structseq object.
3963
Georg Brandl3ee81df2008-05-17 18:14:43 +00003964- Patch #1816: Added sys.flags structseq. It exposes the status of
3965 most command line arguments and PYTHON* environment variables.
Christian Heimesf31b69f2008-01-14 03:42:48 +00003966
Georg Brandl3ee81df2008-05-17 18:14:43 +00003967- Objects/structseq.c: Implemented new structseq representation. The
3968 patch makes structseqs (e.g. the return value of os.stat) more
3969 readable.
Christian Heimes9c201962008-01-14 03:33:52 +00003970
Georg Brandl3ee81df2008-05-17 18:14:43 +00003971- Patch #1700288: added a type attribute cache that caches method

Georg Brandl3ee81df2008-05-17 18:14:43 +00003983- Improve some exception messages when Windows fails to load an
3984 extension module. Now we get for example '%1 is not a valid Win32
3985 application' instead of 'error code 193'.

Georg Brandl3ee81df2008-05-17 18:14:43 +00003996- Compiler now generates simpler and faster code for dictionary
3997 literals. The oparg for BUILD_MAP now indicates an estimated
3998 dictionary size. There is a new opcode, STORE_MAP, for adding
3999 entries to the dictionary.

4042
Georg Brandl21e99f42010-03-07 15:23:59 +00004043- The enumerate() built-in function is no longer bounded to sequences
Georg Brandl3ee81df2008-05-17 18:14:43 +00004044 smaller than LONG_MAX. Formerly, it raised an OverflowError. Now,
4045 automatically shifts from ints to longs.
Raymond Hettinger8f669372007-10-03 21:18:11 +00004046
Georg Brandl3ee81df2008-05-17 18:14:43 +00004047- Issue #1686386: Tuple's tp_repr did not take into account the
4048 possibility of having a self-referential tuple, which is possible
4049 from C code. Nor did object's tp_str consider that a type's tp_str
4050 could do something that could lead to an inifinite recursion.
4051 Py_ReprEnter() and Py_EnterRecursiveCall(), respectively, fixed the
4052 issues.
Brett Cannon0b14f242007-09-30 19:45:10 +00004053
Georg Brandl3ee81df2008-05-17 18:14:43 +00004054- Issue #1164: It was possible to trigger deadlock when using the
4055 'print' statement to write to a file since the GIL was not released
4056 as needed. Now PyObject_Print() does the right thing along with
4057 various tp_print implementations of the built-in types and those in
4058 the collections module.

Brett Cannon1e534b52007-09-07 04:18:30 +00004067- Issue #1202533: Fix infinite recursion calls triggered by calls to
Georg Brandl3ee81df2008-05-17 18:14:43 +00004068 PyObject_Call() never calling back out to Python code to trigger
4069 recursion depth updates/checks. Required the creation of a static
4070 RuntimeError instance in case normalizing an exception put the
4071 recursion check value past its limit. Fixes crashers

Georg Brandl3ee81df2008-05-17 18:14:43 +00004088 __*__ attributes. (Some already existed, e.g., __doc__ and
4089 __name__.)

4095 calls.
4096
Collin Winter62903052007-05-18 23:11:24 +00004097- except clauses may now be spelled either "except E, target:" or
Georg Brandl3ee81df2008-05-17 18:14:43 +00004098 "except E as target:". This is to provide forwards compatibility
4099 with Python 3.0.

Vinay Sajip8549ce32007-05-06 17:53:37 +00004106- When __slots__ are set to a unicode string, make it work the same as
Neal Norwitzcbd9ee62007-04-14 05:25:50 +00004107 setting a plain string, ie don't expand to single letter identifiers.
4108
Raymond Hettinger13936692007-04-11 18:40:58 +00004109- Request #1191699: Slices can now be pickled.
4110
Raymond Hettinger4db5fe92007-04-12 04:10:00 +00004111- Request #1193128: str.translate() now allows a None argument for

4113 remaining characters.
4114
Georg Brandl5cb76c12007-03-21 09:00:39 +00004115- Patch #1682205: a TypeError while unpacking an iterable is no longer

4119
Guido van Rossum143b5642007-03-23 04:58:42 +00004120- Bug #1683368: The object.__init__() and object.__new__() methods are
4121 now stricter in rejecting excess arguments. The only time when
4122 either allows excess arguments is when it is not overridden and the
4123 other one is. For backwards compatibility, when both are
4124 overridden, it is a deprecation warning (for now; maybe a Py3k
Guido van Rossum234b1ff2007-03-23 19:39:01 +00004125 warning later). Also, type.__init__() insists on the same signature
4126 as supported by type.__new__().
Guido van Rossum143b5642007-03-23 04:58:42 +00004127
Georg Brandl3ee81df2008-05-17 18:14:43 +00004128- Patch #1675423: PyComplex_AsCComplex() now tries to convert an
4129 object to complex using its __complex__() method before falling back
4130 to the __float__() method. Therefore, the functions in the cmath
4131 module now can operate on objects that define a __complex__()
4132 method.

4149
Georg Brandl7b9c5552007-03-12 14:30:05 +00004150- Bug #1678647: write a newline after printing an exception in any
4151 case, even when converting the value to a string failed.
4152
Georg Brandl871f1bc2007-03-12 13:17:36 +00004153- The dir() function has been extended to call the __dir__() method on
Georg Brandl3ee81df2008-05-17 18:14:43 +00004154 its argument, if it exists. If not, it will work like before. This
4155 allows customizing the output of dir() in the presence of a
4156 __getattr__().

4165 parthensized forms. This means complex(repr(x)) now works instead of
4166 raising a ValueError.
Collin Wintere38051d2007-03-09 20:33:07 +00004167
Georg Brandlaa2321b2007-03-07 00:40:28 +00004168- Patch #703779: unset __file__ in __main__ after running a file. This
Georg Brandl3ee81df2008-05-17 18:14:43 +00004169 makes the filenames the warning module prints much more sensible
4170 when a PYTHONSTARTUP file is used.

Georg Brandl0fca97a2007-03-05 22:28:08 +00004183- Patch #1674228: when assigning a slice (old-style), check for the
4184 sq_ass_slice instead of the sq_slice slot.
4185
Georg Brandl3ee81df2008-05-17 18:14:43 +00004186- When printing an unraisable error, don't print exceptions. before
4187 the name. This duplicates the behavior whening normally printing
4188 exceptions.

4269 directly to succeed.

Georg Brandl4e933132006-09-06 20:05:58 +00004271- Bug #1542051: Exceptions now correctly call PyObject_GC_UnTrack.

Guido van Rossum8bc09652008-02-21 18:18:37 +00004330- Removed uses of dict.has_key() from distutils, and uses of

Georg Brandl3ee81df2008-05-17 18:14:43 +00004739- Patch #1530482: add pydoc.render_doc() which returns the

4754
Georg Brandl92a6bae2007-03-13 17:43:32 +00004755- Patch #1603688: ConfigParser.SafeConfigParser now checks values that
Georg Brandl3ee81df2008-05-17 18:14:43 +00004756 are set for invalid interpolation sequences that would lead to
4757 errors on reading back those values.

4811

4813 TestCase and TestSuite subclasses (not instances) are no longer
4814 accepted in TestSuite.addTest(). This should cause no
4815 incompatibility since it never made sense with ordinary subclasses
4816 -- the failure just occurred later, with a more cumbersome
4817 exception.

Gregory P. Smithbde4ae42008-01-17 08:35:49 +00005104 that the SMTP.starttls() caller no longer needs to call ehlo()
5105 beforehand. SMTP.starttls() now raises an exception of the server
Georg Brandl3ee81df2008-05-17 18:14:43 +00005106 does not claim to support starttls. Adds the
5107 SMTP.ehlo_or_helo_if_needed() method. Patch contributed by Bill

Georg Brandl3ee81df2008-05-17 18:14:43 +00005206 time so that opening a database previously created with the DB_DUP
5207 or DB_DUPSORT flag set will keep the proper behavior on subsequent
5208 opens. Specifically: dictionary assignment to a DB object will

Raymond Hettingerdc1d1ba2007-11-07 02:45:46 +00005490- Add a FAST_LOOPS build option that speeds-up looping by trading away
Georg Brandl3ee81df2008-05-17 18:14:43 +00005491 periodic threadstate and signal checking in tight loops. By
5492 default, this option is turned-off. It should only be enabled in
5493 debugged, performance critical applications.

Christian Heimes5b970ad2008-02-06 13:33:44 +00005550
Georg Brandl3ee81df2008-05-17 18:14:43 +00005551- ``PySet_Add()`` can now modify a newly created frozenset. Similarly
5552 to ``PyTuple_SetItem``, it can be used to populate a brand new

5567 of w# format code incorrectly truncated the length to an int, even
5568 when PY_SSIZE_T_CLEAN is set. The str.decode method used to return
5569 incorrect results with huge strings.

Georg Brandl3ee81df2008-05-17 18:14:43 +00005599- Added case insensitive comparison methods ``PyOS_stricmp(char*,
5600 char*)`` and ``PyOS_strnicmp(char*, char*, Py_ssize_t)``.
