13-----------------
14
Eric Smithd44b2fc2010-04-02 12:30:56 +000015- Issue #7994: Issue a PendingDeprecationWarning if object.__format__
16 is called with a non-empty format string. This is an effort to
17 future-proof user code. If a derived class does not currently
18 implement __format__ but later adds its own __format__, it would
19 most likely break user code that had supplied a format string. This
20 will be changed to a DeprecationWaring in Python 3.3 and it will be
21 an error in Python 3.4.
22
Antoine Pitroua57df2c2010-03-31 21:32:15 +000023- Issue #8268: Old-style classes (not just instances) now support weak
24 references.
25
Victor Stinner6cbf90f2010-03-25 00:21:53 +000026- Issue #8211: Save/restore CFLAGS around AC_PROG_CC in configure.in, compiler
27 optimizations are disabled when --with-pydebug is used.
28
Victor Stinnerc7790ed2010-03-22 12:36:28 +000029- Issue #1583863: An unicode subclass can now override the __unicode__ method
Victor Stinner95affc42010-03-22 12:24:37 +000030
Benjamin Peterson96545892010-03-21 20:21:00 +000031- Issue #6474: Make error message from passing an inadequate number of keyword
32 arguments to a function correct.
33
Benjamin Peterson0dee9c12010-03-17 20:41:42 +000034- Issue #8164: Don't allow lambda functions to have a docstring.
35
Victor Stinner66644262010-03-10 22:30:19 +000036- Issue #3137: Don't ignore errors at startup, especially a keyboard interrupt
Georg Brandlba83f822010-03-14 09:50:54 +000037 (SIGINT). If an error occurs while importing the site module, the error is
38 printed and Python exits. Initialize the GIL before importing the site
Victor Stinner66644262010-03-10 22:30:19 +000039 module.

Mark Dickinsone096e822010-04-02 10:17:07 +000046- Issue #7279: Comparisons involving a Decimal signaling NaN now
47 signal InvalidOperation instead of returning False. (Comparisons
Mark Dickinsonf3eeca12010-04-02 10:35:12 +000048 involving a quiet NaN are unchanged.) Also, Decimal quiet NaNs
49 are now hashable; Decimal signaling NaNs remain unhashable.
Mark Dickinsone096e822010-04-02 10:17:07 +000050
Mark Dickinson99d80962010-04-02 08:53:22 +000051- Issue #2531: Comparison operations between floats and Decimal
52 instances now return a result based on the numeric values of the
53 operands; previously they returned an arbitrary result based on
54 the relative ordering of id(float) and id(Decimal).
55
Barry Warsawf7f2d6f2010-03-31 21:07:16 +000056- Issue #8233: When run as a script, py_compile.py optionally takes a single
57 argument `-` which tells it to read files to compile from stdin. Each line
58 is read on demand and the named file is compiled immediately. (Original
59 patch by Piotr Ożarowski).
60
61- Issue #3135: Add inspect.getcallargs, which binds arguments to a function
62 like a normal call.
Benjamin Peterson7e213252010-03-30 17:58:13 +000063
Florent Xicluna58b65662010-03-30 16:29:03 +000064- Backwards incompatible change: Unicode codepoints line tabulation (0x0B) and
65 form feed (0x0C) are now considered linebreaks, as specified in Unicode
66 Standard Annex #14. See issue #7643.
Florent Xicluna22b24382010-03-30 08:24:06 +000067 http://www.unicode.org/reports/tr14/
68
Mark Dickinson9588d992010-03-27 11:14:37 +000069- Comparisons using one of <, <=, >, >= between a complex instance and
70 a Fractions instance now raise TypeError instead of returning
71 True/False. This makes Fraction <=> complex comparisons consistent with
72 int <=> complex, float <=> complex, and complex <=> complex comparisons.
73
Michael Foorde6410c52010-03-29 20:04:23 +000074- Addition of ``WeakSet`` to the ``weakref`` module.
75
Vinay Sajipb0623d62010-03-24 14:31:21 +000076- logging: Added LOG_FTP to SysLogHandler and updated documentation.
77
Florent Xicluna176cda12010-03-22 22:52:11 +000078- Issue #8205: Remove the "Modules" directory from sys.path when Python is
79 running from the build directory (POSIX only).
80
Florent Xiclunae1f4c922010-03-22 22:45:50 +000081- Issue #7667: Fix doctest failures with non-ASCII paths.
82
Antoine Pitrou513d9ae2010-03-22 19:59:46 +000083- Issue #7512: shutil.copystat() could raise an OSError when the filesystem
84 didn't support chflags() (for example ZFS under FreeBSD). The error is
85 now silenced.
86
Florent Xicluna9e7a4c92010-03-22 16:07:38 +000087- Issue #7703: ctypes supports both buffer() and memoryview(). The former is
88 deprecated.
89
R. David Murrayc9d1a782010-03-22 15:55:09 +000090- Issue #7860: platform.uname now reports the correct 'machine' type
91 when Python is running in WOW64 mode on 64 bit Windows.
92
Vinay Sajip804899b2010-03-22 15:29:01 +000093- logging: Added getChild utility method to Logger and added isEnabledFor
94 method to LoggerAdapter.
95
Vinay Sajip31e928e2010-03-22 13:02:28 +000096- Issue #8201: logging: Handle situation of non-ASCII and Unicode
97 logger names existing at the same time, causing a Unicode error
98 when configuration code attempted to sort the existing loggers.
99
Vinay Sajip3017a7b2010-03-22 12:33:08 +0000100- Issue #8200: logging: Handle errors when multiprocessing is not
101 fully loaded when logging occurs.
102
Antoine Pitroueee91cd2010-03-26 19:27:16 +0000103- Issue #3890, #8222: Fix recv() and recv_into() on non-blocking SSL sockets.
104 Also, enable the SSL_MODE_AUTO_RETRY flag on SSL sockets, so that blocking
105 reads and writes are always retried by OpenSSL itself.
Antoine Pitrou448da712010-03-21 19:33:38 +0000106
Florent Xiclunacf82fa62010-03-21 12:27:20 +0000107- Issue #8179: Fix macpath.realpath() on a non-existing path.
108

113 or memoryviews.
114
Matthias Klose8b411682010-03-16 10:48:52 +0000115- Issue #4961: Inconsistent/wrong result of askyesno function in tkMessageBox

119
Matthias Klose358e7ff2010-03-15 13:42:23 +0000120- Issue #7356: ctypes.util: Make parsing of ldconfig output independent of
121 the locale.
122
Georg Brandlba83f822010-03-14 09:50:54 +0000123- Issue #7774: Set sys.executable to an empty string if ``argv[0]`` has been
Victor Stinner75227342010-03-12 14:30:26 +0000124 set to an non existent program name and Python is unable to retrieve the real
Georg Brandlba83f822010-03-14 09:50:54 +0000125 program name.
Victor Stinner75227342010-03-12 14:30:26 +0000126
Vinay Sajipecfa08f2010-03-12 09:16:10 +0000127- Issue #8117: logging: Improved algorithm for computing initial rollover time
Georg Brandlba83f822010-03-14 09:50:54 +0000128 for ``TimedRotatingFileHandler`` by using the modification time of an
129 existing log file to compute the next rollover time. If the log file does
130 not exist, the current time is used as the basis for the computation.
Vinay Sajip9098ee42010-03-12 06:01:21 +0000131
Georg Brandlba83f822010-03-14 09:50:54 +0000132- Issue #6472: The ``xml.etree`` package is updated to ElementTree 1.3. The

Florent Xicluna47627d52010-03-08 15:20:28 +0000138 classes.
139
Georg Brandlba83f822010-03-14 09:50:54 +0000140- Issue #7143: email: ``get_payload()`` used to strip any trailing newline from
141 a base64 transfer-encoded payload *after* decoding it; it no longer does.
142 This is a behavior change, so email's minor version number is now bumped, to
143 version 4.0.2, for the 2.7 release.
R. David Murray4617e502010-03-08 02:04:06 +0000144

155 This update drops support for Berkeley DB 4.0, and adds support for 4.8.
Matthias Klose54cc5392010-03-15 12:46:18 +0000156
Matthias Klose817acef2010-03-15 00:02:36 +0000157- Issue #8142: Update libffi to the 3.0.9 release.
158
Georg Brandlba83f822010-03-14 09:50:54 +0000159- Issue #1530559: When passing a non-integer argument to struct.pack with *any*
160 integer format code (one of 'bBhHiIlLqQ'), struct.pack attempts to use the
161 argument's __int__ method to convert to an integer before packing. It also
162 produces a DeprecationWarning in this case. (In Python 2.6, the behaviour
163 was inconsistent: __int__ was used for some integer codes but not for others,
164 and the set of integer codes for which it was used differed between native
165 packing and standard packing.)

194 function declaration, which was kept for backwards compatibility reasons,
195 is now removed (the macro was introduced in 1997!).
196
Larry Hastings402b73f2010-03-25 00:54:54 +0000197- Issue #7992: A replacement PyCObject API, PyCapsule, has been backported
Larry Hastings5ac006d2010-04-02 11:01:35 +0000198 from Python 3.1. All existing Python CObjects in the main distribution
199 have been converted to capsules. To address backwards-compatibility
200 concerns, PyCObject_AsVoidPtr() was changed to understand capsules.

Georg Brandlba83f822010-03-14 09:50:54 +0000446 file position when calling `truncate()`. It would previously change the file
447 position to the given argument, which goes against the tradition of
Antoine Pitrouf3fa0742010-01-31 22:26:04 +0000448 ftruncate() and other truncation APIs. Patch by Pascal Chambon.

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

544Core and Builtins
545-----------------
546
Georg Brandlba83f822010-03-14 09:50:54 +0000547- The ``__complex__()`` method is now looked up on the class of instances to
548 make it consistent with other special methods.
Benjamin Petersonecdae192010-01-04 00:43:01 +0000549
Antoine Pitrou5b7139a2010-01-02 21:12:58 +0000550- Issue #7462: Implement the stringlib fast search algorithm for the `rfind`,
551 `rindex`, `rsplit` and `rpartition` methods. Patch by Florent Xicluna.
552
Mark Dickinson1b34d252010-01-01 17:27:30 +0000553- Issue #5080: A number of functions and methods previously produced a
Georg Brandlba83f822010-03-14 09:50:54 +0000554 DeprecationWarning when passed a float argument where an integer was expected.
555 These functions and methods now raise TypeError instead. The majority of the
556 effects of this change are in the extension modules, but some core functions
557 and methods are affected: notably the 'chr', 'range' and 'xrange' builtins,
558 and many unicode/str methods.

Amaury Forgeot d'Arc8645a5c2009-12-29 22:03:38 +0000568- Issue #7413: Passing '\0' as the separator to datetime.datetime.isoformat()
569 used to drop the time part of the result.
570
Georg Brandlba83f822010-03-14 09:50:54 +0000571- Issue #1811: Improve accuracy and cross-platform consistency for true division
572 of integers: the result of a/b is now correctly rounded for ints a and b (at
573 least on IEEE 754 platforms), and in particular does not depend on the
574 internal representation of a long.
Mark Dickinson46572832009-12-27 14:55:57 +0000575
Georg Brandlba83f822010-03-14 09:50:54 +0000576- Issue #6108: ``unicode(exception)`` and ``str(exception)`` should return the
577 same message when only ``__str__()`` (and not ``__unicode__()``) is overridden
578 in the subclass.
Ezio Melottif84caf42009-12-24 22:25:17 +0000579

Ronald Oussoren92919a62009-12-24 13:30:58 +0000581 executables on OSX.
582
Georg Brandlba83f822010-03-14 09:50:54 +0000583 These executables now work properly with the arch(1) command: ``arch -ppc
584 python`` will start a universal binary version of python in PPC mode (unlike
585 previous releases).
Ronald Oussoren92919a62009-12-24 13:30:58 +0000586
Georg Brandlba83f822010-03-14 09:50:54 +0000587- Issue #1680159: Unicode coercion during an 'in' operation no longer masks the
588 underlying error when the coercion fails for the left hand operand.

Georg Brandlba83f822010-03-14 09:50:54 +0000599- Issue #6963: Added "maxtasksperchild" argument to ``multiprocessing.Pool``,
600 allowing for a maximum number of tasks within the pool to be completed by the
601 worker before that worker is terminated, and a new one created to replace it.

Georg Brandlba83f822010-03-14 09:50:54 +0000608 renaming of `cPickle` to `pickle`. The warning was annoying since there's no

Benjamin Petersonddd392c2009-12-13 19:19:07 +0000644- Issue #7349: Make methods of file objects in the io module accept None as an
645 argument where file-like objects (ie StringIO and BytesIO) accept them to mean
646 the same as passing no argument.
647
Georg Brandlba83f822010-03-14 09:50:54 +0000648- Issue #7348: ``StringIO.StringIO.readline(-1)`` now acts as if it got no

721 when called with invalid values.
Amaury Forgeot d'Arcd7288712009-12-01 21:51:04 +0000722
Georg Brandlba83f822010-03-14 09:50:54 +0000723- Issue #3382: 'F' formatting for float and complex now convert the result to
724 upper case. This only affects 'inf' and 'nan', since 'f' no longer converts
725 to 'g' for large values.
Amaury Forgeot d'Arcd7288712009-12-01 21:51:04 +0000726
Georg Brandlba83f822010-03-14 09:50:54 +0000727- Remove switch from "%f" formatting to "%g" formatting for floats larger than
728 1e50 in absolute value.
Mark Dickinson9dd5e162009-11-23 20:54:09 +0000729
Georg Brandlba83f822010-03-14 09:50:54 +0000730- Remove restrictions on precision when formatting floats. E.g., "%.120g" %
731 1e-100 used to raise OverflowError, but now gives the requested 120
732 significant digits instead.

739 10.6.
Ronald Oussoren315cd0c2009-11-19 16:25:21 +0000740
Georg Brandlba83f822010-03-14 09:50:54 +0000741- Issue #7117: ``repr(x)`` for a float x returns a result based on the shortest
742 decimal string that's guaranteed to round back to x under correct rounding
743 (with round-half-to-even rounding mode). Previously it gave a string based on
744 rounding x to 17 decimal digits. repr(x) for a complex number behaves
745 similarly. On platforms where the correctly-rounded strtod and dtoa code is
746 not supported (see below), repr is unchanged.
Mark Dickinsonb678de82009-11-19 18:41:49 +0000747
Georg Brandlba83f822010-03-14 09:50:54 +0000748- Issue #7117: On almost all platforms: float-to-string and string-to-float
749 conversions within Python are now correctly rounded. Places these conversions
750 occur include: str for floats and complex numbers; the float and complex
751 constructors; old-style and new-style numeric formatting; serialization and
752 deserialization of floats and complex numbers using marshal, pickle and json;
753 parsing of float and imaginary literals in Python code; Decimal-to-float
754 conversion.
Mark Dickinsonb678de82009-11-19 18:41:49 +0000755
Georg Brandlba83f822010-03-14 09:50:54 +0000756 The conversions use a Python-adapted version of David Gay's well-known dtoa.c,
757 providing correctly-rounded strtod and dtoa C functions. This code is
758 supported on Windows, and on Unix-like platforms using gcc, icc or suncc as
759 the C compiler. There may be a small number of platforms on which correct
760 operation of this code cannot be guaranteed, so the code is not used: notably,
761 this applies to platforms where the C double format is not IEEE 754 binary64,
762 and to platforms on x86 hardware where the x87 FPU is set to 64-bit precision
763 and Python's configure script is unable to determine how to change the FPU
764 precision. On these platforms conversions use the platform strtod and dtoa,
765 as before.

Georg Brandlba83f822010-03-14 09:50:54 +0000767- Issue #7117: Backport round implementation from Python 3.x. ``round()`` now
768 uses the correctly-rounded string <-> float conversions described above (when
769 available), and so produces correctly rounded results that will display nicely
770 under the float repr. There are two related small changes: (1) round now
771 accepts any class with an ``__index__()`` method for its second argument (but
772 no longer accepts floats for the second argument), and (2) an excessively
773 large second integer argument (e.g., ``round(1.234, 10**100)``) no longer
774 raises an exception.

Antoine Pitrouf8387af2009-03-23 18:41:45 +0000991- Issue #4688: Add a heuristic so that tuples and dicts containing only
Georg Brandlba83f822010-03-14 09:50:54 +0000992 untrackable objects are not tracked by the garbage collector. This can reduce
993 the size of collections and therefore the garbage collection overhead on
994 long-running programs, depending on their particular use of datatypes.

Amaury Forgeot d'Arc05e34492008-09-10 22:04:45 +00002557- Issue #3743: In a few places, PY_FORMAT_SIZE_T was incorrectly used with
2558 PyString_FromFormat or PyErr_Format to display size_t values. The macro
2559 PY_FORMAT_SIZE_T is designed to select the correct format for the OS
2560 ``printf`` function, whereas PyString_FromFormat has an independent
2561 implementation and uses "%zd" on all platforms for size_t values.
2562 This makes a difference on win64, where ``printf`` needs "%Id" to display
2563 64bit values.

2658 warnings.catch_warnings() along with some API cleanup. Expanding the tests
2659 for catch_warnings() also led to an improvement in the raising of a
2660 DeprecationWarning related to warnings.warn_explicit().

2684
Amaury Forgeot d'Arc293924b2008-09-02 23:19:56 +00002685- Issue #2975: When compiling several extension modules with Visual Studio 2008

Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00002726What's New in Python 2.6 beta 3?
2727================================
2728
Barry Warsaw07a4a382008-08-21 01:15:08 +00002729*Release date: 20-Aug-2008*
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00002730
2731Core and Builtins
2732-----------------
2733
Guido van Rossumf8402962008-08-20 15:01:50 +00002734- Issue #1878: Remove Py_TPFLAGS_HAVE_VERSION_TAG from
2735 Py_TPFLAGS_DEFAULT when not building the core. This means 3rd party
2736 extensions do not automatically benefit from the class attribute
2737 cache; they will have to explicitly add Py_TPFLAGS_HAVE_VERSION_TAG
2738 to their tp_flags field if they care. This is a backwards
2739 compatibility feature; in 3.0, all types will use the cache by
2740 default.
2741
Benjamin Petersonf647dc12008-08-20 01:27:30 +00002742- Keyword arguments can now follow starred arguments. (``f(a, *args,
2743 keyword=23)`` is now valid syntax.)
2744
Thomas Heller0ad5ae02008-08-19 19:25:04 +00002745- ctypes function pointers that are COM methods have a boolean True
2746 value again.
2747
Martin v. Löwisf91d46a2008-08-12 14:49:50 +00002748- Issue #3139: Make buffer-interface thread-safe wrt. PyArg_ParseTuple,
2749 by denying s# to parse objects that have a releasebuffer procedure,
2750 and introducing s*.
2751
Georg Brandl1e13ea92008-08-11 09:07:59 +00002752- Issue #3537: Fix an assertion failure when an empty but presized dict
2753 object was stored in the freelist.
2754
Mark Dickinsonb6467572008-08-04 21:30:09 +00002755- Issue #1481296: Make long(float('nan')) and int(float('nan')) raise
2756 ValueError consistently across platforms.
2757
Amaury Forgeot d'Arc39fd6722008-07-31 21:28:03 +00002758- Issue #3479: On platforms where sizeof(int) is smaller than sizeof(long)
2759 (64bit Unix, for example), unichr() would truncate its argument and return
2760 u'\x00' for unichr(2**32). Now it properly raises an OverflowError.
2761
Neal Norwitze7d8be82008-07-31 17:17:14 +00002762- Apply security patches from Apple.
2763
Amaury Forgeot d'Arc246daed2008-07-31 00:42:16 +00002764- Issue #2542: Now that issubclass() may call arbitrary code, ensure that
2765 PyErr_ExceptionMatches returns 0 when an exception occurs there.
2766
Antoine Pitrou92f82162008-07-25 22:22:08 +00002767- Issue #1819: function calls with several named parameters are now on
2768 average 35% faster (as measured by pybench).
2769
Amaury Forgeot d'Arce4921fe2008-07-21 22:00:38 +00002770- Issue #2378: An unexpected UnboundLocalError or NameError could appear when
2771 the python debugger steps into a class statement: the free variables (local
2772 variables defined in an outer scope) would be deleted from the outer scope.
2773
Gregory P. Smith0470bab2008-07-22 04:46:32 +00002774- Issue #2620: Overflow checking when allocating or reallocating memory
2775 was not always being done properly in some python types and extension
2776 modules. PyMem_MALLOC, PyMem_REALLOC, PyMem_NEW and PyMem_RESIZE have
2777 all been updated to perform better checks and places in the code that
2778 would previously leak memory on the error path when such an allocation
2779 failed have been fixed.
2780
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00002781Library
2782-------
2783

2785
Benjamin Petersone977ad42008-08-20 01:42:01 +00002786- The methods ``is_in_tuple()``, ``is_vararg()``, and ``is_keywordarg()`` of
2787 symtable.Symbol have been deprecated for removal in 3.0 and the next release.
2788
Amaury Forgeot d'Arc351ffb82008-08-18 19:23:47 +00002789- Issue #2234: distutils failed for some versions of the cygwin compiler. The
2790 version reported by these tools does not necessarily follow the python
2791 version numbering scheme, so the module is less strict when parsing it.
2792
Nick Coghlanf70385a2008-08-18 12:42:46 +00002793- Issue #2235: Added Py3k warnings for types which will become unhashable
2794 under the stricter __hash__ inheritance rules in 3.0. Several types
2795 which did not meet the rules for hash invariants and were already
2796 unhashable in 3.0 have now been explicitly flagged as unhashable in
2797 2.6 as well (collections.Mapping, collections.Set, unittest.TestSuite,
2798 xml.dom.minidom.NamedNodeMap, numbers.Number, UserList.UserList)
2799
Brett Cannon88f801d2008-08-18 00:46:22 +00002800- Update __all__ for cookielib, csv, os, urllib2, and weakref to include things

2804
Brett Cannon46225e72008-08-18 00:36:52 +00002805- Remove unneeded imports of 'sys' and 'warnings' from 'io'.

Brett Cannon25c9d6a2008-08-17 22:10:11 +00002807- Remove unneeded imports of 'warnings' from shelve, filecmp, and dummy_thread.
2808
Hirokazu Yamamoto41a81eb2008-08-17 13:10:46 +00002809- Issue #3575: Incremental decoder's decode function now takes bytearray
2810 by using 's*' instead of 't#'.
2811
Mark Dickinson3e4caeb2009-02-21 20:27:01 +00002812- Issue #2222: Fixed reference leak when occurred os.rename()
Hirokazu Yamamoto7f30a682008-08-17 09:46:56 +00002813 fails unicode conversion on 2nd parameter. (windows only)
2814
Facundo Batista94f243a2008-08-17 03:38:39 +00002815- Issue 2464. urllib2 now supports a malformation in the URL received
2816 in a redirect.
2817
Brett Cannonabe423e2008-08-16 21:47:07 +00002818- Silence the DeprecationWarning raised when importing mimetools in
Brett Cannon721b1452008-08-16 22:00:27 +00002819 BaseHTTPServer, cgi (and rfc822), httplib.
Brett Cannonabe423e2008-08-16 21:47:07 +00002820
Facundo Batistaeb90b782008-08-16 14:44:07 +00002821- Issue #2776: fixed small issue when handling an URL with double slash
2822 after a 302 response in the case of not going through a proxy.
2823
Antoine Pitroub90a8be2008-08-15 21:03:21 +00002824- Issue #2676: in the email package, content-type parsing was hanging on
2825 pathological input because of quadratic or exponential behaviour of a
2826 regular expression.
2827
Antoine Pitrou11ec65d2008-08-14 21:04:30 +00002828- Issue #3476: binary buffered reading through the new "io" library is now
2829 thread-safe.
2830
Brett Cannonbf3157b2008-08-14 05:00:03 +00002831- Silence the DeprecationWarning of rfc822 when it is imported by mimetools
2832 since mimetools itself is deprecated. Because modules are cached, all
2833 subsequent imports of rfc822 will not raise a visible DeprecationWarning.
2834
Antoine Pitrou9fcd4b32008-08-11 17:21:36 +00002835- Issue #3134: shutil referenced undefined WindowsError symbol.
2836
Robert Schuppenies14646332008-08-10 11:01:53 +00002837- Issue #1342811: Fix leak in Tkinter.Menu.delete. Commands associated to
2838 menu entries were not deleted.
2839
Brett Cannon83e81842008-08-09 23:30:55 +00002840- Copied the implementation of reduce() to _functools.reduce() to have a
2841 version that did not raise a DeprecationWarning under -3.
2842
Antoine Pitrou76b8bee2008-08-09 17:27:23 +00002843- Issue #3205: When iterating over a BZ2File fails allocating memory, raise
2844 a MemoryError rather than silently stop the iteration.
2845
Guido van Rossum59ce9012008-08-09 14:55:34 +00002846- Issue #3487: sre "bytecode" validator. Passing invalid "re-bytecode"
2847 to _sre.compile() will now be rejected. This should not affect anybody
2848 since the re.compile() function never generates invalid re-bytecode.
2849
Skip Montanaroa032bf42008-08-08 22:52:51 +00002850- Issue #3436: Make csv.DictReader's fieldnames attribute a property so that

2855 the reload() built-in has been removed.
2856
Brett Cannon7e30b672008-08-04 21:52:25 +00002857- Changed code in the following modules/packages to remove warnings raised
Brett Cannonc1b76e42008-08-09 23:06:16 +00002858 while running under the ``-3`` flag: aifc, asynchat, asyncore, bdb, bsddb,

Antoine Pitroude781a42008-08-09 12:43:23 +00002869 asking for a specific length. This problem only affected files opened
2870 using the new "io" module, not the built-in open() function.

Mark Dickinson64b7e502008-07-16 09:40:03 +00002932- Issue #3360: Fix incorrect parsing of '020000000000.0', which
2933 produced a ValueError instead of giving the correct float.
2934
Eric Smitha5fa5a22008-07-16 00:11:49 +00002935- Issue #3083: Add alternate (#) formatting for bin, oct, hex output
2936 for str.format(). This adds the prefix 0b, 0o, or 0x, respectively.
2937
Mark Dickinson7103aa42008-07-15 19:08:33 +00002938- Issue #3008: the float type has a new instance method 'float.hex'
2939 and a new class method 'float.fromhex' to convert floating-point
2940 numbers to and from hexadecimal strings, respectively.
2941
Nick Coghlan6d6bd442008-07-15 15:40:22 +00002942- Issue #2235: __hash__ is once again inherited by default. To allow
2943 collections.Hashable to remain meaningful in the presence of the
2944 default hash implementation (object.__hash__), it is now possible
2945 to explicit block inheritance of hash by setting __hash__=None at
2946 the Python level, or tp_hash=PyObject_HashNotImplemented at the C
2947 level.
2948
Nick Coghlanb028f502008-07-13 14:52:36 +00002949- Issue #3221: Issue a RuntimeWarning instead of raising SystemError if
2950 the parent module cannot be found while performing an absolute import.
2951 This means that an incorrectly defined __package__ attribute will
2952 now only prevent relative imports in that module rather than causing
2953 all imports from that module to fail.
2954
Nick Coghlan14ff9942008-07-08 14:21:42 +00002955- Issue #2517: Allow unicode messages in Exceptions again by correctly

2965 another thread's dictionary.
2966
Mark Dickinson1ec2fcd2008-06-20 14:53:43 +00002967- Issue #3004: Minor change to slice.indices(): the start and stop
2968 arguments are now treated identically, making the behaviour easier
2969 to describe and understand. For example, slice(None, -10,
2970 1).indices(9) now returns (0, 0, 1) instead of (0, -1, 1), and
2971 slice(None, 10, -1).indices(10) returns (9, 9, -1) instead of (9,
2972 10, -1).

Georg Brandl278fc502008-07-19 12:46:12 +00002974- Issue #3219: Calling a function with repeated keyword arguments,
2975 f(a=2, a=23), would not cause a syntax error. This was a regression
2976 from 2.4 caused by the switch to the new compiler.

3015 both unnecessary (HTTP allows text content to be sent in several forms) and

Georg Brandl3ee81df2008-05-17 18:14:43 +00003488- Issue #1631171: Re-implement the 'warnings' module in C (the
3489 original Python code has been kept as backup). This will allow for
3490 using the 'warning's machinery in such places as the parser where
3491 use of pure Python code is not possible. Both the ``showarning()``
3492 and ``formatwarning()`` gain an optional 'line' argument which is
3493 not called by default for backwards-compatibility reasons. Setting
3494 ``warnings.showwarning()`` to an implementation that lacks support
3495 for the ``line`` argument will raise a DeprecationWarning.

Georg Brandl3ee81df2008-05-17 18:14:43 +00003558- Issue #2550: The approach used by client/server code for obtaining
3559 ports to listen on in network-oriented tests has been refined in an
3560 effort to facilitate running multiple instances of the entire
3561 regression test suite in parallel without issue.
3562 test_support.bind_port() has been fixed such that it will always
3563 return a unique port -- which wasn't always the case with the
3564 previous implementation, especially if socket options had been set
3565 that affected address reuse (i.e. SO_REUSEADDR, SO_REUSEPORT). The
3566 new implementation of bind_port() will actually raise an exception
3567 if it is passed an AF_INET/SOCK_STREAM socket with either the
3568 SO_REUSEADDR or SO_REUSEPORT socket option set. Furthermore, if
3569 available, bind_port() will set the SO_EXCLUSIVEADDRUSE option on
3570 the socket it's been passed. This currently only applies to
3571 Windows. This option prevents any other sockets from binding to the
3572 host/port we've bound to, thus removing the possibility of the
3573 'non-deterministic' behaviour, as Microsoft puts it, that occurs
3574 when a second SOCK_STREAM socket binds and accepts to a host/port
3575 that's already been bound by another socket. The optional preferred
3576 port parameter to bind_port() has been removed. Under no
3577 circumstances should tests be hard coding ports!
3578
3579 test_support.find_unused_port() has also been introduced, which will
3580 pass a temporary socket object to bind_port() in order to obtain an
3581 unused port. The temporary socket object is then closed and
3582 deleted, and the port is returned. This method should only be used
3583 for obtaining an unused port in order to pass to an external program
3584 (i.e. the -accept [port] argument to openssl's s_server mode) or as
3585 a parameter to a server-oriented class that doesn't give you direct
3586 access to the underlying socket used.
3587
3588 Finally, test_support.HOST has been introduced, which should be used
3589 for the host argument of any relevant socket calls (i.e. bind and
3590 connect).
Trent Nelsone41b0062008-04-08 23:47:30 +00003591
3592 The following tests were updated to following the new conventions:
Georg Brandl3ee81df2008-05-17 18:14:43 +00003593 test_socket, test_smtplib, test_asyncore, test_ssl, test_httplib,
Trent Nelsone41b0062008-04-08 23:47:30 +00003594 test_poplib, test_ftplib, test_telnetlib, test_socketserver,
3595 test_asynchat and test_socket_ssl.
3596
Georg Brandl3ee81df2008-05-17 18:14:43 +00003597 It is now possible for multiple instances of the regression test
3598 suite to run in parallel without issue.

3865-----------------
3866
Fred Drakea8ee94b2008-03-01 02:45:07 +00003867- Issue #2051: pyc and pyo files are no longer created with permission
Barry Warsaw52973612008-03-01 02:23:38 +00003868 644. The mode is now inherited from the py file.
Christian Heimes40346852008-02-23 17:52:07 +00003869
Georg Brandlad61bc82008-02-23 15:11:18 +00003870- Issue #2067: file.__exit__() now calls subclasses' close() method.
3871
3872- Patch #1759: Backport of PEP 3129 class decorators.
Christian Heimes5224d282008-02-23 15:01:05 +00003873
Vinay Sajipb7edfc42008-04-02 21:10:23 +00003874- Issue #1881: An internal parser limit has been increased. Also see
Facundo Batistafc2d0102008-02-23 12:01:13 +00003875 issue 215555 for a discussion.
3876
Eric Smitha73fbe72008-02-23 03:09:44 +00003877- Added the future_builtins module, which contains hex() and oct().
3878 These are the PEP 3127 version of these functions, designed to be
3879 compatible with the hex() and oct() builtins from Python 3.0. They
3880 differ slightly in their output formats from the existing, unchanged
3881 Python 2.6 builtins. The expected usage of the future_builtins
3882 module is:
3883 from future_builtins import hex, oct
3884
Eric Smith7ef40bf2008-02-20 23:34:22 +00003885- Issue #1600: Modifed PyOS_ascii_formatd to use at most 2 digit
3886 exponents for exponents with absolute value < 100. Follows C99
3887 standard. This is a change on Windows, which would use 3 digits.
3888 Also, added 'n' to the formats that PyOS_ascii_formatd understands,
3889 so that any alterations it does to the resulting string will be
3890 available in stringlib/formatter.h (for float.__format__).
3891
Eric Smith5a3c1352008-02-19 13:21:56 +00003892- Implemented PEP 3101, Advanced String Formatting. This adds a new
3893 builtin format(); a format() method for str and unicode; a
3894 __format__() method to object, str, unicode, int, long, float, and
3895 datetime; the class string.Formatter; and the C API
3896 PyObject_Format().
3897
Georg Brandl3ee81df2008-05-17 18:14:43 +00003898- Fixed several potential crashes, all caused by specially crafted
3899 __del__ methods exploiting objects in temporarily inconsistent
3900 state.
Amaury Forgeot d'Arc632fad32008-02-16 20:55:24 +00003901
Vinay Sajipb7edfc42008-04-02 21:10:23 +00003902- Issue #2115: Important speedup in setting __slot__ attributes. Also
Georg Brandl3ee81df2008-05-17 18:14:43 +00003903 prevent a possible crash: an Abstract Base Class would try to access
3904 a slot on a registered virtual subclass.
Amaury Forgeot d'Arc60d6c7f2008-02-15 21:22:45 +00003905
Georg Brandl3ee81df2008-05-17 18:14:43 +00003906- Fixed repr() and str() of complex numbers with infinity or nan as
3907 real or imaginary part.
Christian Heimes2f0da532008-02-15 06:57:08 +00003908
Georg Brandl3ee81df2008-05-17 18:14:43 +00003909- Clear all free lists during a gc.collect() of the highest generation
3910 in order to allow pymalloc to free more arenas. Python may give back
3911 memory to the OS earlier.
Christian Heimes3b718a72008-02-14 12:47:33 +00003912
Georg Brandl3ee81df2008-05-17 18:14:43 +00003913- Issue #2045: Fix an infinite recursion triggered when printing a
3914 subclass of collections.defaultdict, if its default_factory is set
3915 to a bound method.
Amaury Forgeot d'Arcb01aa432008-02-08 00:56:02 +00003916
Christian Heimesf75dbef2008-02-08 00:11:31 +00003917- Fixed a minor memory leak in dictobject.c. The content of the free
3918 list was not freed on interpreter shutdown.
3919
Georg Brandl21e99f42010-03-07 15:23:59 +00003920- Limit free list of method and built-in function objects to 256
Georg Brandl3ee81df2008-05-17 18:14:43 +00003921 entries each.
Christian Heimes6075a822008-02-06 12:44:34 +00003922
Georg Brandl3ee81df2008-05-17 18:14:43 +00003923- Patch #1953: Added ``sys._compact_freelists()`` and the C API
3924 functions ``PyInt_CompactFreeList`` and ``PyFloat_CompactFreeList``
Christian Heimes422051a2008-02-04 18:00:12 +00003925 to compact the internal free lists of pre-allocted ints and floats.
3926
Georg Brandl3ee81df2008-05-17 18:14:43 +00003927- Issue #1983: Fixed return type of fork(), fork1() and forkpty()
3928 calls. Python expected the return type int but the fork familie
3929 returns pi_t.
Christian Heimes951cc0f2008-01-31 23:08:23 +00003930
Georg Brandl3ee81df2008-05-17 18:14:43 +00003931- Issue #1678380: Fix a bug that identifies 0j and -0j when they
3932 appear in the same code unit.
Mark Dickinson105be772008-01-31 22:17:37 +00003933
Georg Brandl3ee81df2008-05-17 18:14:43 +00003934- Issue #2025: Add tuple.count() and tuple.index() methods to comply
3935 with the collections.Sequence API.
Raymond Hettinger5b07ebc2008-02-07 00:54:20 +00003936

Georg Brandl3ee81df2008-05-17 18:14:43 +00003940- Added ``PyType_ClearCache()`` and ``sys._clear_type_cache`` to clear
3941 the internal lookup cache for ref leak tests.
Christian Heimes908caac2008-01-27 23:34:59 +00003942
Georg Brandl3ee81df2008-05-17 18:14:43 +00003943- Patch #1473257: generator objects gain a gi_code attribute. This is
3944 the same object as the func_code attribute of the function that
3945 produced the generator.
Georg Brandl0cdf9a32008-01-26 14:14:20 +00003946
Georg Brandl3ee81df2008-05-17 18:14:43 +00003947- Issue #1920: "while 0" statements were completely removed by the
3948 compiler, even in the presence of an "else" clause, which is
3949 supposed to be run when the condition is false. Now the compiler
3950 correctly emits bytecode for the "else" suite.
Amaury Forgeot d'Arc31eaafe2008-01-24 22:59:25 +00003951
Guido van Rossumeead05f2008-01-24 18:21:02 +00003952- A few crashers fixed: weakref_in_del.py (issue #1377858);
3953 loosing_dict_ref.py (issue #1303614, test67.py);
3954 borrowed_ref_[34].py (not in tracker).
3955
Vinay Sajipd7cf32e2008-01-24 12:43:33 +00003956- Issue #1069410: The "can't load dll" message box on Windows is
Christian Heimesb2302ba2008-01-23 17:15:06 +00003957 suppressed while an extension is loaded by calling SetErrorMode in
3958 dynload_win.c. The error is still reported properly.
3959
Georg Brandl3ee81df2008-05-17 18:14:43 +00003960- Issue #1915: Python compiles with --enable-unicode=no again. However
Christian Heimes082c9b02008-01-23 14:20:50 +00003961 several extension methods and modules do not work without unicode
3962 support.
3963
Georg Brandl26543b12008-01-21 18:36:51 +00003964- Issue #1882: when compiling code from a string, encoding cookies in the
3965 second line of code were not always recognized correctly.
3966
Georg Brandl14404b62008-01-19 19:27:05 +00003967- Issue #1679: "0x" was taken as a valid integer literal.
3968
Georg Brandl6caad7d2008-01-26 14:19:22 +00003969- Issue #1865: ``bytes`` as an alias for ``str`` and b"" as an alias "" were
Christian Heimes288e89a2008-01-18 18:24:07 +00003970 added.
3971
Christian Heimesc94e2b52008-01-14 04:13:37 +00003972- sys.float_info / PyFloat_GetInfo: The floating point information
3973 object was converted from a dict to a specialized structseq object.
3974
Georg Brandl3ee81df2008-05-17 18:14:43 +00003975- Patch #1816: Added sys.flags structseq. It exposes the status of
3976 most command line arguments and PYTHON* environment variables.
Christian Heimesf31b69f2008-01-14 03:42:48 +00003977
Georg Brandl3ee81df2008-05-17 18:14:43 +00003978- Objects/structseq.c: Implemented new structseq representation. The
3979 patch makes structseqs (e.g. the return value of os.stat) more
3980 readable.
Christian Heimes9c201962008-01-14 03:33:52 +00003981
Georg Brandl3ee81df2008-05-17 18:14:43 +00003982- Patch #1700288: added a type attribute cache that caches method
3983 accesses, resulting in speedups in heavily object-oriented code.

3991 envvar and sys.dont_write_bytecode attribute. All these can be set
3992 to forbid Python to attempt to write compiled bytecode files.
Georg Brandl2da0fce2008-01-07 17:09:35 +00003993
Georg Brandl3ee81df2008-05-17 18:14:43 +00003994- Improve some exception messages when Windows fails to load an
3995 extension module. Now we get for example '%1 is not a valid Win32
3996 application' instead of 'error code 193'.
Amaury Forgeot d'Arce0b76952008-01-04 02:04:15 +00003997

Georg Brandl3ee81df2008-05-17 18:14:43 +00004004 and INF. float("nan"), float("inf") and float("-inf") now work on
4005 every platform with IEEE 754 semantics.

Georg Brandl3ee81df2008-05-17 18:14:43 +00004007- Compiler now generates simpler and faster code for dictionary
4008 literals. The oparg for BUILD_MAP now indicates an estimated
4009 dictionary size. There is a new opcode, STORE_MAP, for adding
4010 entries to the dictionary.

4040 file can now be directly executed by passing their name to the
4041 interpreter. The directory/zipfile is automatically inserted as the
4042 first entry in sys.path.

4053
Georg Brandl21e99f42010-03-07 15:23:59 +00004054- The enumerate() built-in function is no longer bounded to sequences
Georg Brandl3ee81df2008-05-17 18:14:43 +00004055 smaller than LONG_MAX. Formerly, it raised an OverflowError. Now,
4056 automatically shifts from ints to longs.
Raymond Hettinger8f669372007-10-03 21:18:11 +00004057
Georg Brandl3ee81df2008-05-17 18:14:43 +00004058- Issue #1686386: Tuple's tp_repr did not take into account the
4059 possibility of having a self-referential tuple, which is possible
4060 from C code. Nor did object's tp_str consider that a type's tp_str
4061 could do something that could lead to an inifinite recursion.
4062 Py_ReprEnter() and Py_EnterRecursiveCall(), respectively, fixed the
4063 issues.
Brett Cannon0b14f242007-09-30 19:45:10 +00004064
Georg Brandl3ee81df2008-05-17 18:14:43 +00004065- Issue #1164: It was possible to trigger deadlock when using the
4066 'print' statement to write to a file since the GIL was not released
4067 as needed. Now PyObject_Print() does the right thing along with
4068 various tp_print implementations of the built-in types and those in
4069 the collections module.

Brett Cannon1e534b52007-09-07 04:18:30 +00004078- Issue #1202533: Fix infinite recursion calls triggered by calls to
Georg Brandl3ee81df2008-05-17 18:14:43 +00004079 PyObject_Call() never calling back out to Python code to trigger
4080 recursion depth updates/checks. Required the creation of a static
4081 RuntimeError instance in case normalizing an exception put the
4082 recursion check value past its limit. Fixes crashers
4083 infinite_rec_(1|2|4|5).py.

Neal Norwitz0ac60192007-05-27 04:08:54 +00004098- Add new attribute names for function objects. All the func_* become
Georg Brandl3ee81df2008-05-17 18:14:43 +00004099 __*__ attributes. (Some already existed, e.g., __doc__ and
4100 __name__.)

4106 calls.
4107
Collin Winter62903052007-05-18 23:11:24 +00004108- except clauses may now be spelled either "except E, target:" or
Georg Brandl3ee81df2008-05-17 18:14:43 +00004109 "except E as target:". This is to provide forwards compatibility
4110 with Python 3.0.

Vinay Sajip8549ce32007-05-06 17:53:37 +00004117- When __slots__ are set to a unicode string, make it work the same as
Neal Norwitzcbd9ee62007-04-14 05:25:50 +00004118 setting a plain string, ie don't expand to single letter identifiers.
4119
Raymond Hettinger13936692007-04-11 18:40:58 +00004120- Request #1191699: Slices can now be pickled.
4121
Raymond Hettinger4db5fe92007-04-12 04:10:00 +00004122- Request #1193128: str.translate() now allows a None argument for
4123 translations that only remove characters without re-mapping the
4124 remaining characters.
4125
Georg Brandl5cb76c12007-03-21 09:00:39 +00004126- Patch #1682205: a TypeError while unpacking an iterable is no longer

4130
Guido van Rossum143b5642007-03-23 04:58:42 +00004131- Bug #1683368: The object.__init__() and object.__new__() methods are
4132 now stricter in rejecting excess arguments. The only time when
4133 either allows excess arguments is when it is not overridden and the
4134 other one is. For backwards compatibility, when both are
4135 overridden, it is a deprecation warning (for now; maybe a Py3k
Guido van Rossum234b1ff2007-03-23 19:39:01 +00004136 warning later). Also, type.__init__() insists on the same signature
4137 as supported by type.__new__().
Guido van Rossum143b5642007-03-23 04:58:42 +00004138
Georg Brandl3ee81df2008-05-17 18:14:43 +00004139- Patch #1675423: PyComplex_AsCComplex() now tries to convert an
4140 object to complex using its __complex__() method before falling back
4141 to the __float__() method. Therefore, the functions in the cmath
4142 module now can operate on objects that define a __complex__()
4143 method.
Georg Brandl2b869942007-03-17 16:08:45 +00004144
Georg Brandl3ee81df2008-05-17 18:14:43 +00004145- Patch #1623563: allow __class__ assignment for classes with
4146 __slots__. The old and the new class are still required to have the
4147 same slot names.

4154 its type.

4160
Georg Brandl7b9c5552007-03-12 14:30:05 +00004161- Bug #1678647: write a newline after printing an exception in any
4162 case, even when converting the value to a string failed.
4163
Georg Brandl871f1bc2007-03-12 13:17:36 +00004164- The dir() function has been extended to call the __dir__() method on
Georg Brandl3ee81df2008-05-17 18:14:43 +00004165 its argument, if it exists. If not, it will work like before. This
4166 allows customizing the output of dir() in the presence of a
4167 __getattr__().

4176 parthensized forms. This means complex(repr(x)) now works instead of
4177 raising a ValueError.
Collin Wintere38051d2007-03-09 20:33:07 +00004178
Georg Brandlaa2321b2007-03-07 00:40:28 +00004179- Patch #703779: unset __file__ in __main__ after running a file. This
Georg Brandl3ee81df2008-05-17 18:14:43 +00004180 makes the filenames the warning module prints much more sensible
4181 when a PYTHONSTARTUP file is used.

Georg Brandl0fca97a2007-03-05 22:28:08 +00004194- Patch #1674228: when assigning a slice (old-style), check for the
4195 sq_ass_slice instead of the sq_slice slot.
4196
Georg Brandl3ee81df2008-05-17 18:14:43 +00004197- When printing an unraisable error, don't print exceptions. before
4198 the name. This duplicates the behavior whening normally printing
4199 exceptions.

Georg Brandl3ee81df2008-05-17 18:14:43 +00004732 AttributeError instead of an IOError when the server's response

Georg Brandl3ee81df2008-05-17 18:14:43 +00004750- Patch #1530482: add pydoc.render_doc() which returns the

4765
Georg Brandl92a6bae2007-03-13 17:43:32 +00004766- Patch #1603688: ConfigParser.SafeConfigParser now checks values that
Georg Brandl3ee81df2008-05-17 18:14:43 +00004767 are set for invalid interpolation sequences that would lead to
4768 errors on reading back those values.

4824 TestCase and TestSuite subclasses (not instances) are no longer
4825 accepted in TestSuite.addTest(). This should cause no
4826 incompatibility since it never made sense with ordinary subclasses
4827 -- the failure just occurred later, with a more cumbersome
4828 exception.

Gregory P. Smithbde4ae42008-01-17 08:35:49 +00005115 that the SMTP.starttls() caller no longer needs to call ehlo()

Georg Brandl3ee81df2008-05-17 18:14:43 +00005117 does not claim to support starttls. Adds the

Gregory P. Smithec10a4a2007-11-05 02:32:26 +00005216- pybsddb.sf.net Bug #477182: Load the database flags at database open
Georg Brandl3ee81df2008-05-17 18:14:43 +00005217 time so that opening a database previously created with the DB_DUP
5218 or DB_DUPSORT flag set will keep the proper behavior on subsequent
5219 opens. Specifically: dictionary assignment to a DB object will
5220 replace all values for a given key when the database allows
5221 duplicate values. DB users should use DB.put(k, v) when they want
5222 to store duplicates; not DB[k] = v.

Georg Brandl3ee81df2008-05-17 18:14:43 +00005502 periodic threadstate and signal checking in tight loops. By
5503 default, this option is turned-off. It should only be enabled in

Georg Brandl3ee81df2008-05-17 18:14:43 +00005562- ``PySet_Add()`` can now modify a newly created frozenset. Similarly
5563 to ``PyTuple_SetItem``, it can be used to populate a brand new

5576
Georg Brandl3ee81df2008-05-17 18:14:43 +00005577- Issue #1521: On 64bit platforms, using PyArgs_ParseTuple with the t#
5578 of w# format code incorrectly truncated the length to an int, even
5579 when PY_SSIZE_T_CLEAN is set. The str.decode method used to return
5580 incorrect results with huge strings.

Georg Brandl3ee81df2008-05-17 18:14:43 +00005610- Added case insensitive comparison methods ``PyOS_stricmp(char*,
5611 char*)`` and ``PyOS_strnicmp(char*, char*, Py_ssize_t)``.
Christian Heimes000a0742008-01-03 22:16:32 +00005612
